The California Water Management Planning Act of 1983 (Act), as amended, requires urban water suppliers to develop an UWMP every five years in the years ending in zero and five. Under normal circumstances, all 2010 UWMPs would have been due for submittal to the Department of Water Resources (DWR) ,by December 31, 2010; however, Senate Bill (SB) 7-7 (or SBX7-7) provided an additional six months to retail urban water supply agencies to allow them to conduct additional required water conservation analyses. Thus, the City's 2010 UWMR must now be adopted by July 1, 2011 and submitted to DWR on or before August,1, 2011. In addressing urban water management issues,,,the legislature made a number of significant declarations including: • The waters of the state are a limited and renewable resource subject to ever increasing demands; • Conservation and efficient use of urban water supplies are of statewide concern; • Successful implementation of plans is,�best accomplished at the local level; • Conservation I and effic'ient use of water shall be actively pursued to protect both the people of the state and their water resources; j • Conservation and efficient use of urban water supplies shall be a guiding criterion in.public decisions; and • Urban water suppliers shall be required to develop water management plans to achieve conservation and efficient use. The City of Huntington Beach (City) 2010 UWMP has been prepared in compliance with the requirements of the Act, as amended to 20101 (Appendix A), and includes the following: • Service Area Facilities • Water Sources and Supplies • Water Quality Information California Water Code, Division 6, Part 2.6; §10610, et. seq. Established by Assembly Bill 797 (1983). I 1B -349- Item 16. - 19 City o Huntington Beach Section 1 2010 Urban Water Allanagement Plan • Water Reliability Planning • Water Use Provisions • Water Demand Management Measures * Water Shortage Contingency Plan * Water Recycling 1.2 UWIVIP UPDATE PREPARATION The City's 2010 UWMP revises the 2005 UWMP prepared by Psomas for Huntington Beach and incorporates changes enacted by legislation including SB 1087 (2005), AB 1376 (2007), AB 1465 (2010), and SBX7-7 (2010). A brief summary of each of these legislative changes, as well as other related legislative'changes, follows: • SB 1087 (2005) — Requires urban retail,water suppliers to include single family and multiple family projections for lower income and affordable households in oj their UWMPs. This legislation is intended to assist the water agencies in complying with the requirements of Government Code Section 65589.7, which requires water suppliers to grant a priority for provision of service to housing units affordable to lower income households. • AB 1376 (2007) — Requires each urban water supplier to notify the Planning Department of any City or County within which the supplier provides water with at least 60 days prior notice that the supplier will be reviewing the plan and considering amendments or changes to it. • AB 1465 (2010) — Clarifies that urban water suppliers that are members of the California Urban Water Conservation 'Council (CUWCC) and comply with the provisions of the "Memorandum of Understanding Regarding Urban Water Conservation in California"2 dated December 10, 2008, as it may-be amended (MOU), may submit their annual reports required under the CUWCC MOU as evidence of compliance without the need for any additional documentation in their UWMPs. • SBX7-7'(2Qj_0) — Requires urban retail water suppliers to include the following information in their 2010 UWMPs with respect to a targeted 20 percent water conservation reduction by 2020: (1) baseline daily per capita use; (2) urban water use target; (3) interim water use target; and (4) compliance daily per capita water use, including technical bases and supporting data for those determinations. • SBX7-7 (2010) — Extends the deadline for submittal of urban retail water suppliers 2010 UWMPs until July 1, 2011, to provide sufficient time to prepare 2 The Memorandum of Understanding Regarding Urban Water Conservation in California (MOU) was adopted in September 1991 by a large number of water suppliers, public advocacy organizations and other interested groups and most recently amended on December 10, 2008. The MOU created the California Urban Water Conservation Council and established 16 Best Management Practices (BMPs) for urban water conservation,recently refined to 14 BMPs. Item 16. - 20 11 f 3 -3_51'0- City of Huntington Beach 2010 Utban Water&4anagement Plan Section I ............. ........ the additional required water conservation analyses described in the previous bullet. Other legislation, which does not directly impact UWMPs, but affects eligibility for grants and loans, includes: • AB 1420 (2007) — This legislation contains several provisions relating to urban water management plans,including: • Conditions eligibility for State grant and loan funding to an urban water supplier awarded or administered by DWR, the State Water Resources Control Board, or California Bay-Delta Authority or its successor agency on the following factors: (1) the implementation of Water demand management measures, including the extent of compliance with conservation measures described in the previously referenced "Memorandum' of Understanding Regarding Urban Water Conservation in California." • Requires DWR, in consultation with the State Water Resources Control Board and the California Bay-Delta Authority or its successor agency, to develop eligibility requirements to implement the foregoing grant and loan conditions. • Requires DWR, in consultation with the CUWCC, to convene a technical panel no later than January 1, 2009 to provide information and recommendations to the Department and the Legislature on new demand management measures, technologies,and approaches. The panel and DWR must report to the legislature on their findings no later than January 1, 2010 and each five years thereafter. © SBX3-27 (2009) — Exempts projects funded by the American Recovery and Reinvestment Act of 2009.(ARRA) from the conditions placed on state funding for water management to urban water suppliers regarding implementation of water conservation measures that were implemented under AB 1420. * SBX7-7 — Repeals the existing grant funding conditions of AB 1420 on July 1, 2016 if they are not extended or altered prior to this date. After July 1, 2016, urban water retail water suppliers are required to be in compliance with the 20 percent by 2020 water use reduction goals to be eligible for state water management grants or loans. The UWMP also incorporates water use efficiency efforts the City has implemented or is considering implementing pursuant to the previously referenced Memorandum of Understanding Regarding Urban Water Conservation in California (MOU). The City of Huntington Beach became signatory and adopted the MOU on December 19, 2000. The sections in this Plan correspond to the outline of the Act, specifically Article 2, Contents of Plans, Sections 10631, 10632, and 10633. The sequence used for the required information, however, differs slightly in order to present information in a manner reflecting the unique characteristics of the City's water utility. 1113 -351- Item 16. - 21 City of HcrrItingtot7 Beach Section :° 2010 Urban Water Management tt Plant To assist Department of Water Resources staff in reviewing this UWMP, a copy of the DWR's suggested checklist entitled Urban Water Management Plan Checklist, Organized by Subjed is provided in Appendix B.

This UWMP details the specifics as they relate to the City of Huntington Beach Public Works Department and its service area and will refer to MWDOC, Metropolitan, OCWD and OCSD throughout. Appendix D lists the numerous references used benefiting the development of this Plan. The UWMP is intended to serve as a general, flexible, and open-ended document that periodically can be updated to reflect changes in the Orange County water supply trends, and conservation and water use efficiency policies. This Plan, along with the City's Water Master Plan and other City planning documents, will be used by City staff to guide the City's water use and management efforts through the year 2015, when the UWMP is required to be updated. 1.3 HUNTINGTON BEACH WATER SERVICE AREA Location The City of Huntington Beach is located 35,miles southeast of Los Angeles and 90 miles northwest of San Diego along the Southern California coast of Orange County as shown in Figure 1-1. The City's water service area is° 27.3 square miles of which 0.2 square miles is the City of Sunset Beach. The City is-generally flat, with elevations ranging from a low of about 5 feet below., to 120 feet above sea level. Huntington Beach is predominately residential, although 60,000 people,are currently employed by over 10,000 businesses in the City.4 The City has also has 71 parks and public facilities5, and 8 '/2 miles of beaches. The City also supplies water to Sunset Beach, which is approximately 68 acres of unincorporated land located off Pacific Coast Highway near Huntington Harbor. Climate Characteristics The City of Huntington Beach is located in an area known as the South Coast Air Basin (SCAB). The SCAB climate is characterized by what is known as Southern California's Mediterranean' climate: a semi-arid environment with mild winters, warm summers and moderate rainfall. The climate for the City is consistent with coastal Southern California. The general region lies in the semi-permanent high-pressure zone of the eastern Pacific. As a result, the climate is mild, tempered by cool sea breezes. The usually mild climatological pattern is interrupted infrequently by periods of extremely hot weather, winter storms, or Santa Ana winds. 4 Per City website,bttp:/hvti .ei.h€€F�tintc��-beacb.ca.t€si'busi€�css; 'Per City website,http:/Av w.ci.h;€ntin_>tc>n-lic acb.ca.Us;Residericsr�nrks facilities/ii rlcs;1-6 Item 16. - 24 1113 -354- City of Huntington Beach 2010 Urban Water Management Plan Section I -- - .......... ................... .................... ............................--...................... .................................... ............. .................--....................The average annual temperature varies throughout the Basin, averaging 62 degrees Fahrenheit at the coast where the city is located.

It is an indication of how much water crops; lawn, garden, and trees need for healthy growth and productivity. For ET to take place, the following conditions have to be met. First, water has to be present at the surface. Second, there must be some form of energy to convert the liquid water into a water vapor. Third, there must be a mechanism to transport the water vapor away from the evaporating surface. Precipitation and irrigation are the two primary sources of water that plants use. Plant leaves and soil surfaces temporarily retain some part of the water applied to the soil. This part is readily available, for evaporation. The remaining part infiltrates into the soil. Plants-extract the infiltrated water through their roots and transport it up to their leaves for photosynthesis, a process by which plants produce glucose (sugar). Many factors affect ET including: • Weather parameters such as solar radiation, air temperature, relative humidity and wind speed; • Soil factors such as soil texture, structure, density and chemistry; and • Plant factors such as plant type, root depth, foliar density, height and stage of growth. 6 Data obtained from Western Regional Climate Center(WRCC),Desert Research Institute, Reno,Nevada (h :!i`w �v.�rrcc.dri.edu-eri-bin'cii, tAlt�.pl?cafi175 ); WRCC program administered by the National Oceanic and Atmospheric Administration (NOAA); data extracted from monitoring Station 046175 at Newport Beach Harbor(closest WRCC station to I-tuntington Beach)covering the period January I, 1921 through August 31,2010. Item 16. - 26 1113 -356- City of Htintington Beach 2010 Urban Water-Management Plan Section I ................. ------- ....................._.._._..........-- - Although ET can be measured using such devices as lysimeters, estimating ET using analytical and empirical equations is a common practice because measurement methods are expensive and time consuming. Most ET equations were developed by correlating measured ET to measured weather parameters that directly or indirectly affect ET. Since there are so many factors affecting ET, it is extremely difficult to formulate an equation that can produce estimates of ET under different sets of conditions. Therefore, the idea of a reference crop evapotranspiration was developed by researchers. Reference ET is the ET rate of a reference crop expressed in inches or millimeters. Reference crops are either grass or alfalfa surfaces whose biophysi6I characteristics have been studied extensively. ET from a standardized grass surface is commonly denoted as ETo whereas ET from a standardized alfalfa surface is denoted as ETr. The American Society of Civil Engineers (ASCE) recommends the use of ETos and ETrs, respectively, where "s" stands for standardized surface conditions. The' logic behind the o, evapotranspiration idea is to set up weather stations on standardized-,reference surfaces for which most of the biophysical properties used in ET equations are known. ET from such surfaces can then be estimated using these kno'wn parameters and measured weather parameters. Then a crop factor, commonly known as the "crop coefficient" of"Kc" is used to calculate the actual evapotranspiration (ETc),,fQr a specific crop in the same microclimate as the weather station site. - The California Irrigation Management Information System,,(CIMIS), Department of Water Resources, Office of Water Efficiency is,using well-watered actively growing closely clipped grass that,is,completely shading the soil.I as a reference crop at most of its over 130 weather stations. Therefore, reference evapotranspiration is mostly referred to as ETo on the CIMIS website, although there are a few notable exceptions with ETr. There are many theoretical and empirical equations around the world to estimate ETo. The choice of any one method depends-on the accuracy of the equation under a given condition and tbeavailabilify'of the required data. For reference surfaces with known biophysical properties, .the main factors affecting ETo include solar radiation, relative humidity/vapor pressure, air temperature and wind speed. Therefore ETo can be estimated "quite accurately using a model (a series of mathematical equations). The monthly average ETo data shown in Table 1.3-2 has been extracted.from the CIMIS Irvine station (#75), which is the closest station to Huntington Beach (located on the grounds of a University of California field station at an elevation of 410 feet). This station was activated on October 7, 1987.7 For additional information,refer to the CIMIS website at: -i 7 5&src- info .............-- ....... ........... 1-9 1113 -357- Item 16. - 27 City of Huntington Beach Section 1 2010 Urban Water Management Plan Table 1.3-2 Average Evapotranspiration (ETo) Rates for Huntington Beach Area Jan Feb Mar Apr May Jun Jul Aug Sep, Oct; ,Nov 'Dec.,",; Total ETo 218 2.49 3.67 4.71 5.18 5.87 6.29 6.17 4.57 3.66 2.59 2.25 49.63 (inches) Demographics The population of the City's water service area is currently estimated at 204,831, and is growing slowly, as there is very little remaining vacant land. The City provides water to over 52,300 service connections. The Huntington Beach water service area is predominantly residential with over 90 percent of water service connections serving single-family and multi-family residences. The average population per household reflected :below, is for the City of Huntington Beach which makes up almost the entire water service area (excludes Sunset Beach with a population of approximately 1,300,). The population per household for the City was estimated at 2.59 by the Center for Demographic Research (CDR) at California State University Fullerton in 2010. Utilizing CDR's 2010 Orange County Projections; adjusting to include the City's approved plans for the Downtown Area Specific Plan and the Beach Edinger Corridor Specific Plan, and adding the Sunset Beach population, generates a 7.3 percent increase in population over the next 25 years in the City's water service area.

It is a charter city, administered by a council/administrator government. From 1936 to 1964, the water system serving Huntington Beach was owned and operated by the Southern California Water Company. In 1964, the City purchased the private system and the City's Water Division was established as a Division of the Public Works Department. In 2003, the Public Works Sewer Section was incorporated into the Water Division to form the Utilities Division. The City is the principal water retailer within the City boundaries including the Sunset Beach area. The Public Works Department is responsible for operating and maintaining wells, reservoirs, imported water connections, distribution pipelines, fire hydrants, water meters and related infrastructure, and for meter reading and billing. The Public Works Department also conducts comprehensive water quality testing and monitoring programs and develops long range operational and engineering plans designed to prepare for future needs and contingencies. The West Orange County Water Board is a joint.p6wers agreement between the cities of Huntington Beach, Garden,Grove, Westminster and Seall-'Beach for the ownership and operation of two large capacity imported water transmission lines (OC-9 and OC-35). The Public Works Department performs operation and maintenance of the lines. The City of Huntington Beach is 56.1 percent owner and acts as General Manager/Engineer. The Public Works Department establishes an annual operation budget managed through the Water Fund. Water Fund revenues are received from monthly water use and connection fees billed to water customers. By ordinance, revenues and expenditures for the Water Fund must balance, and the annual Water Fund budget is developed consistent with this premise. The annual budget includes programs for Engineering, Administration, Water Quality, Water Production., Water Maintenance, Water Meters, and Water Billing. Personnel, operating and capital outlay/ equipment replacement costs are determined for each program. In addition, a capital projects budget is designed to address primarily 9) replacements and upgrades of various water facilities and pipelines. In 1995, the City Council adopted a Water Master Plan (WMP) and an accompanying Financial Plan. To fund improvements recommended in the WMP, a surcharge was established for water customers in December 1995. In addition, a capital facilities charge was instituted on all new residential development. Revenues from these charges are placed into the WMP Fund and used for capital improvements administered through the Public Works Department. The City updated its 1995 WMP in 2005 and is currently developing a 2011 WMP Update, which will address water needs for the current and future growth of the City. 11B -359- Item 16. - 29 City of Huntington Beach Section 1 2010 Urban Pater Management ent Plan Service Area The Public Works Department supplies customers throughout the City of Huntington Beach, including the Sunset Beach area (which is undergoing the process of being annexed). Figure 1-2 shows the City limits and service areas, as well as the location of key water supply facilities, as described below. Water System Facilities Groundwater is pumped from 10 active wells located throughout, the City. The age, depth, design flow and'production data for the active wells, wells not in use, and abandoned wells are summarized in Section 2. MWDOC wholesales imported water to the City from Metropolitan., Metropolitan treats water supplied to the City at the Robert B. Diemer Filtration Plant in northern Orange County and the Joseph Jensen Filtration Plant in Granada Hills. The City's water distribution system is connected to Metropolitan transmission mains at OC-9, OC-35 and OC-44 located respectively along the northeast, northwest, and southeast sides of the City. The Public Works Department also operates four storage and distribution reservoirs with a combined capacity of 55 million gallons. The storage system is supported with four booster stations located at the reservoir sites. The booster pumps have a total capacity of 58,690 gallons per minute, which is adequate to keep the, system pressurized under peak flow conditions. �.._ 1-12 Item 16. - 30 1113 -360- City of Huntington Beach 2010 Urban Water Management Plan Section 1 ........... ................. ..........................--11.............-................... ............................... ................. ...................... .......................... ..--......................

The agencies which work in concert to provide these services are the Metropolitan Water District of Southern California (Metropolitan), the Municipal Water District of Orange County (MWDOC)and the Orange County Water District(OCWD). Metropolitan Water District of Southern California (Metropolitan) Metropolitan was formed in the late 1920's. At that time, Orange County was mostly an agriculturally based economy with the cities of Santa Ana,Anahei M' ,4,,and Fullerton as the primary centers of urban development. Although other cities and residential communities existed at that time, it was these three cities that joined ten others located in Southern California, to form Metropolitan in 1928. Collectively, these charter members recognized the limited water supplies available within the region, and realized that continued prosperity and economic development of Southern California depended upon the acquisition and careful management of an adequate supplemental water supply. This foresight made the continued development of Southern California and Orange County possible. Metropolitan imports water from northern California via the State Water Project (SWP) and from the Colorado River Aqueduct (CRA) to supply water to most of southern California. As a wholesaler, Metropolitan has no retail customers, and distributes treated and untreated water directly to its 26 member agencies. One such member agency is MWDOC. Metropolitan's service area is depicted in Figure 2-1.9 9 Service area map extracted from Metropolitan's website at: litto:"V,7"v V—.mll�� -)-J 1113 -363- Item 16. - 33 City of Huntington ton Beach section 21 2010 Urban Water Mana ernent Plan Figure 2-1 Metropolitan n Water District Service Area '� J�F y&ys' � 4 lA',�1 _ „^e"5yg 3✓ 8 P y.

The communities surrounding the Lower Santa Ana Groundwater Basin realized that the local underground supply might not be sufficient to mPPt fi,ture demUndol of*he area. MWDOC was formed for the purpose of contracting with Metropolitan to acquire supplemental import water supplies from northern California and the Colorado River for use within the Orange County area. MWDOC is Metropolitan's second largest wholesale member agency. MWDOC represents 28 member agencies, including 14 special districts and 14 city water departments. MWDOC provides imported water to all of Orange County except for the cities of Anaheim, Fullerton and Santa Ana. It is through MWDOC that the City of Huntington Beach purchases imported water from Metropolitan.

As part of its original formation, OCWD was established by a special act (Act), of the State of California Legislature. This legislation is found in the State of California Statutes, Water — Uncodified Acts, Act 5683, as amended." The basin is managed by OCWD under the Act, which functions as a statutorily-imposed physical solution. Section 77 of the Act states that, `nothing in this act contained shall be so construed as to affect or impair the vested right of any person, association or corporation to the use of water.12 According to the Act, the City has the right to construct and operate groundwater-producing facilities in.the basin. The Act also empowers OCWD to impose replenishment assessments and basin equity assessments on production and to require registration of water-producing facilities and the filing of certain reports; however, OCWD is expressly prohibited from limiting extraction unless a producer agrees.13 The basin is managed by OCWD for the benefit of municipal, agricultural and private groundwater producers. OCWD has 19 major producers extracting water from the Orange County groundwater basin (basin) serving a population of approximately 2.3 million.14 Carefully managed by OCWD in collaboration with the other water and wastewater agencies, the growing population can be assured of a secure water supply from the groundwater source. Processes such as groundwater recharge of the Santa Ana River, recycling of wastewater, conservation and water use efficiency, and creative water purchases have aided in replenishing the groundwater basin to desired levels to meet required demands. OCWD's service area is depicted'in Figure 2-3.15 West Orange County Water Board(WOCWB) As discussed earlier, the WOCWB is a Joint Powers Agency between four participating agencies. The members include the City of Huntington Beach, the City of Garden Grove, the City of Westminster, and the City of Seal Beach. The board consists of five members, With the City of Huntington Bcacr, having two seats. The board meets quarterly and manages surface water deliveries from Metropolitan (through MWDOC) to the agencies._ The board oversees the maintenance of two feeder pipelines that connect to the treated surface water supply. The pipelines have a capacity of 21 CFS and 45 CFS. Each of the member agencies has paid for the capacity of the feeder pipelines and directly pays MWDOC for the use of water.

These percentages are..established through OCWD's all'owable Basin Pumping Percentage (BPP). The BPP is typically set by OCWD on an annual basis. However, OCWD does have the option of revising the BPP as needed. Actual percentages vary somewhat on an annual basis depending on the extent in-lieu delivery. programs are implemented and groundwater levels (e.g., in 2003/04, the City's water supply was 66 percent imported water and 34 percent groundwater. Current and projected water supplies from imported water and groundwater are shown in Table 2.2-1 and described in subsequent sections. 2-5) 11B -367- Item 16. - 37 Cily of Huntington Beach Section 2 2010 Urban Water Management P/an Table 2.2-1 City of Huntington Beach Current and Planned Water Supplies in AFY (Normal Water Year) O� 5, 2"7' U 20 pp Y1,1911 rc MWDOC - Import 11,197 21,370 25,180 29,230 33,270 31,810 30,420 Groundwater Production 18,271 20,070 20,220 20,480 20,970 21,280 21,490 Total Water Supply 29,468 41,440 45,400 49,710 54,240 53,090 51,910 [1]Actual 2010 supply used, refer to Appendix E.

Because 2010 was a Metropolitan Water Allocation Year and not a Normal Water Year, there was no surplus. Imported Water In 2010 approximately 38 percent of the City's,water supply came from imported water wholesaled by MWDOC through Metropolitan. Imported water is delivered from northern California via the State Water Project and--from the Colorado River, and is treated at the Robert B. Diemer and Joseph Jensen Filtration Plants before the water is delivered to the City. The City maintains three imported water connections to the Metropolitan system. The characteristics of these connections are shown in Table 2.2-2. OC-9 is located at the intersection of Dale and Katella Streets in the City of Stanton, and enters the City at the intersection of Newland and Edinger Streets. OC-35 is located at the same intersection and enters Huntington,Beach at the intersection of Springdale and Glenwood Streets. OC- 9 and OC-35 are under,the jurisdiction of the West Orange County Water Board. OC-44 is located at the East Orange County Feeder #2, and flow is delivered to the City's service area through a 24- to 42-inch transmission main Jointly owned by the City and Mesa Consolidated Water District. A secondary metering station, also Jointly owned, is located on Adams Avenue at the Santa Ana River.

Although this program has been temporarily placed on hold due Item 16. - 38 1 1B -368- City of Huntington Beach 20 10 Urban Water Management Plan Section 2 primarily to statewide water shortage issues, the program may be re-instituted when water supplies become more plentiful. OCWD, MWDOC, and Metropolitan have developed a successful and efficient In-lieu Program to increase storage in the groundwater basin and anticipate working together on future programs. One such future program is the proposed Surplus Water Program. The Surplus Water Program will allow the City to take direct Metropolitan deliveries into the City's distribution system in lieu of producing water from the Orange County groundwater basin. This In-lieu Program indirectly replenisbes,,tbe basin by avoiding pumping. In the In-lieu Program, OCWD requests the City,to"limit pumping to defined volumes from specified wells. The City then takes replacement ,water through its import connections, which is purchased by OCWD from Metropolitan, (through MWDOQ. OCWD purchases the water at a reduced rate, and then bills the City the amount it would have had to pay for energy and the Replenishment Assessment (RA) if it had produced the water from its wells. The deferred local production results in water being left in local storage for future use. Reservoirs The City maintains four potable water,storage reservoirs (Overmyer, Peck, Springdale, and Edwards Hill) with a total capacity'of 55million gallons:The City's supply sources fill these reservoirs when demands are low and pumps draw,water from the reservoirs and pressurize it into the City's water system durin'g`demandp6iiods. Groundwater Orange County Groundwater Basin The Orange County Groundwater Basin (Basin) underlies the north half of Orange County beneath broad lowlands. The Basin covers an area of approximately 350 square miles, bordered by the Coyote and Chino Hills to the north, the Santa Ana Mountains to the northeast, the Pacific Ocean to the southwest, and terminates at the Orange County line to the northwest, where its aquifer systems continue into the Central. Basin of Los Angeles County. The aquifers comprising the Basin extend over 2,000 feet deep and form a complex series of interconnected sand and gravel deposits. Groundwater supply currently meets approximately 62 percent of the water supply demand for all of Orange County that overlies the Basin. This amount can be adjusted as needed based on Basin hydrologic conditions,but is typically set on an annual basis. During the water year July 2008 to June 2009, total Basin production for all agencies was 324,147 AF compared with an overall demand of 456,913 AF. A total of 28,425 AF of supplemental water was used for groundwater replenishment and seawater barrier maintenance to prevent seawater intrusion from occurring in areas of the Basin adjacent 2-7 I 1B -369- Item 16. - 39 City of Huntington Beach Section 2 2010 Urban Water Management Plan to the ocean in Huntington Beach, Costa Mesa and Fountain Valley.16 The Basin generally operates as a reservoir in which the net amount of water stored is increased in wet years to allow for managed overdrafts in dry years. The Basin is recharged primarily from local rainfall (greater in wet years), base flow from the Santa Ana River (much of which is actually recycled wastewater from treatment plants in Riverside and San Bernardino Counties), imported water percolated into the Basin, and highly treated recycled wastewater directly recharged via spreading basins into the Basin. The production capability of the Basin is being increased as a result of a variety of specific management initiatives including increased wastewater reclamation. The Basin is not adjudicated and based on the Department of Water Resources' official departmental bulletins, California's Groundwater Bulletin j IS Updated 2003 and Bulletin 160, the California Water Plan Update 2009, the Basin is not specifically identified as a basin in an overdraft condition. However, the California Water Plan Update does state that groundwater overdraft is a challenge for the South Coast Hydrologic Region", which includes the Basin. The Basin is considere&in an overdraft condition by OCWD, however the groundwater levels and amount of"overdraft,fluctuate over time. OCWD continually monitors groundwater level trends and has collected data since 1962. OCWD's Groundwater Management Plan summarizes the accumulated overdraft and water level elevations within the basin. ,. Based on OCWD's July 2009 Groundwater 'Management Plan Update, the target accumulated overdraft is 100,000 AF'8. An overdraft condition reduces localized high groundwater levels and increases the ability to recharge storm events from the Santa Ana River. OCWD estimates that ithe,,Basin can safely be operated on a short-term emergency basis with a maximum accumulated overdraft of approximately 500,000 AF. The accumulated overdraft on June.30, 2009 was 'estimated to be 347,000 AF.19 With an accumulated overdraft of 200;000 AF, the basin is considered 99.7 percent full; with an overdraft of 400,000 AF it is considered 99.4 percent full with a full basin containing 66 MAF"of groundwater in storage.20 In an effort to eliminate long-term overdraft conditions, OCWD developed a comprehensive computer-based groundwater flow model to study and better understand the basin's reaction.to pumnina and recharge- OCWD has also implemented a monitoring program to track dynamic conditions including groundwater production, storage, 16 Orange County Water District,2008-09 Engineer's Report available on OCWD's website at: http://www.ocwd.com.`Publications---'tewsletters/ca-4 3.aspx,Executive Summary,page 1 17 The California Water Plan Update 2009 is available on DWR's website at: 11t�_"tiff wi,i .watea2lan.water.ca.,zov/docslcwpu2009:0310fitiaUv3 southcoast cwp 009.E;references to groundwater challenges can be found in the Volume 3 Regional Update for the South Coast Region s Orange County Water District,Groundwater Management Plan,July 2009 Update available on OCWD's website at: http:%www.ocwd.cons'Publications---Newsletters,%ca-43.aspx,page 6-11;an electronic copy of this document will also be provided on CD to DWR(Appendix H) y Orange County Water District,2008-09 Engineer's Report available on OCWD's website at: hap: www.ocwd.coni:'Ptiblicatik)iis---Newslettei-s/c,1-43.q��lix,page 4 '`0 Orange County Water District,Groundwater Management Plan,July 2009 Update available on OCWD's website at:http:!�vtiviv.oc�vd.comi'Publications---Newsletters:'ca-43.asm,page 6-9 2-8 Item 16. - 40 1113 -3 7 0- City of Huntington Beach 2010 Urban Water&4anagement Plan Section 2 elevations, seawater intrusion, and quality. Components of this monitoring program include the request for the City and other groundwater producers to provide their groundwater production to OCWD on a monthly basis, yearly measurement of groundwater levels, water quality monitoring, and prevention of sea water intrusion. Basin Management Strategies Since its formation in 1933, OCWD has invested in seawater intrusion control (injection barriers), recharge facilities, wastewater recycling, laboratories and basin monitoring to effectively manage the basin. Some of these programs include: Groundwater Replenishment System — As of January 2008' OCWD began recharging recycled water from the Groundwater Replenishment System (GWRS). The GWRS, the largest water purification project of its kind in the world, can currently produce up to 72,000 AFY of recycled water, and has increased Orange County's water independence by providing a locally controlled, ontrolled, drought-proof supply of safe, high-quality water. The Environmental Impact Report (EIR) has been completed and design is underway for a GWRS Expansion Project to increase production to' 'over 101,000 AFY. Other processes such as recycling of wastewater, conservation and water use efficiency programs, and creative water purchases have aided in replenishing the basin to desired levels to meet required demands. Recharge Facilities — OCWD currently owns and operates approximately 1,000 acres of recharge spreading facilities located in cities of Anaheim and Orange, adjacent to the Santa Ana River (SAR) and Santiago Creek. OCWD has built a recharge system that provides the majority of groundwater supplied, by the District. The 17 major recharge facilities in the Anaheim/Orange area are grouped into four major components: the Main River System, the Off-River System, the'Deep Basin System, and the Burris Pit/Santiago System. Each system,has a series of percolation spreading basins, either shallow or deep, whose sidewalls and bottoms allow for percolation into the underlying aquifer. Seawater Intrusion Barriers — OCWD's Talbert Seawater Intrusion Barrier is composed of a series of injection wells that span the 2.5-mile-wide Talbert Gap between the Newport and Huntington mesas. The Talbert Barrier wells can inject approximately 42 million gallons per day.(mgd) of water into four aquifer zones. Injecting water through ni I z:1 the wells forms a hydraulic barrier to seawater that would otherwise migrate inland toward areas of groundwater production. The Alamitos Seawater Intrusion Barrier is composed of a series of injection wells that span the Los Angeles/Orange County line in the Seal Beach-Long Beach area. It is operated by the Los Angeles County Department of Public Works (LACDPW) in cooperation with OCWD and the Water Replenishment District (WRD). The source of this water is a blend of purified wastewater from WRD and potable supplies from Metropolitan. Also, the Alamitos Seawater Intrusion Barrier includes four extraction 1113 -371- Item 16. - 41 City of Huntington Beach Section 2 2010 Urban Water Managen7 nt Plan wells located seaward of the injection barrier to create a pumping trough to remove the degraded brackish groundwater. Groundwater Monitoring — OCWD has one of the most sophisticated groundwater monitoring programs in the country. The District runs more than 350,000 analyses of water from more than 650 wells every year. OCWD performs nearly 50 percent more water quality tests than it is required to do in order to ensure the highest water quality possible. In 2004, OCWD completed a 10-year, $10 million Santa Ana River Water Quality and Health Effects Study, which demonstrated the safety of SAR water as a source for recharging the groundwater basin. A panel of nationally recognized experts provided an independent review of the study and validated its positive results. OCWD Long-Term Facilities Plan (LTFP) OCWD prepared a draft LTFP in 2009 to evaluate potential basin and water quality enhancement projects that may be implemented in a 20-year horizon or planning period. The LTFP was proposed to do the following: • Evaluate projects to cost effectively increase the amount of sustainable basin production and protect water quality • Develop an implementation program"f6r.the recommended projects • Establish the basin's future maximum (target) annual production amount and correspondingly,how much new recharge capacity would be required • Estimate impacts to potential future Replenishment Assessment (RA) rates and long-term Basin Plan Percentages (BPP) which will be discussed in following sections • Evaluate potential annexations Due to difficulties related to the annexation of new lands, annexation was removed from the draft'LTFP and subsequent EIR and the revised LTFP have been adopted by the OCWD Board as a planning document. The LTFP utilizes , information recently developed in OCWD's Groundwater Management Plan and,Recharge Development Study. The LTFP includes a master list of developed and proposed projects. The various projects are grouped into five categories: (1) recharge facilities, (2) water source facilities, (3) basin management facilities, (4) water quality management facilities, and (5) operational improvements facilities. Each project is evaluated using criteria such as technical feasibility, cost, institutional support, functional feasibility, and environmental compliance. The LTFP includes an implementation plan for the 28 recommended projects over the 20 year planning period. Item 16. - 42 11B -3?2- City of Huntington Beach 2010 Urban Water Management flan Section 2 OCWD Groundwater Management Plan As previously referenced, OCWD adopted an update to its 2004 Groundwater Management Plan (GWMP) in July 2009. The GWMP 2009 Update provides information on District operations, lists projects completed since publication of the 2004 report, and discusses plans for future projects and operations. Over fifteen major projects completed between 2004 and 2008 have improved District operations, increased groundwater recharge capacity, and improved water quality.21 The GWMP complies with SB 1938, passed in 2002, which includes a list of items to be,included in a GWMP. The GWMP's objectives include (1) protecting and enhancing;groundwater quality, (2) cost-effectively protecting and increasing the basin's sustainable yield, and (3) increasing the efficiency of OCWD's operations.22 Various programs,policies, goals, and projects are defined in the GWMP to assist OCWD staff in meeting these objectives. The potential projects described in the GWMP are discussed'in further detail in the LTFP. The GWMP describes the following: • Background and purpose of the GWMP • Hydrogeology of the basin • Range of activities and management programs, including groundwater monitoring, groundwater quality management, production management, recharge water supply, and improvement projects • Historical and future,water demands and integrated demand/supply management strategies " • Financial management programs • Recommendations for continued proactive basin management Basin Production Percentage-,, As stated',"F the Basin is unadjudieated. All pumpers within the Basin are permitted to pump from the Basin, but OCWD is charged with managing the groundwater basin. OCWD manages the Basin largely through the Basin Production Percentage (BPP) that it establishes each water year. The BPP is set based on groundwater conditions, availability of imported-water supplies, Santa Ana River runoff, and Basin management objectives. In essence, the BPP represents a set percentage identifying the amount of groundwater all pumpers in the Basin can pump without paying a high "pumping tax" or Basin Equity Assessment to OCWD (described below). Thus, for example, if OCWD establishes a BPP of 65%, all pumpers within the Basin, including the City, can supply 65% of their water needs from groundwater supplies at a cost significantly less than the cost of imported water. The 21 Orange County Water District,Groundwater Management Plan Update,July 9,2009. 72 Ibid. 2-11 1113 -373- Item 16. - 43 City of HL11-dington Beach Section 2 2010 Urban Water Management Plan .............. ................_................- BPP is a major factor for the City in determining the cost of groundwater production. Groundwater production equal to or less than the BPP pays a replenishment assessment (RA). Funds collected by OCWD through RA payments made by all producers in the basin are used to fund groundwater replenishment and recharge programs aimed at ensuring the long-term viability and stability of the Basin. If groundwater production greater than the BPP occurs, a Basin Equity Assessment (BEA) is assessed against the producer of that amount of groundwater produced in excess of the BPP. The BEA is an additional fee(i.e., a higher"pumping,tax") paid on each acre foot of water pumped above the BPP, making the total cost of that water to the City equal to the cost of Tier 2 imported water from Metropolitan. Thus, the BPP creates pricing incentives to ensure that groundwater producers pump within the framework established by the BPP. Like funds collected by OCWD through the RA, funds collected by OCWD through the BEA are also used to fund groundwater replenishment, and recharge, and recycling programs aimed at ensuring the long-term viability and stability of the Basin. The programs funded by the RA and the BEA include all,o'f the groundwater 'replenishment, recharge, and recycling programs discussed herein. Such flexibility in producing over the BPP guarantees the City and other water,utilities in Orange'County the ability to provide water to their customers during periods 6fv' a'rying water availability. Since the BPP was originally established, in 1962, it'has,varied from 62 to 89 percent. The average BPP over ifs:.42-year history is'71.1 percent. Based on discussions with OCWD staff and background analysis provided by OCWD dated September 2010, the current sustainable BPP was determined to be-62 percent, which is also where it was set for the 2010-11 year. Long-term projections of,the BPP range from 62 to 65 percent plus or minus 5 percent based on a Myriad of factors. When Metropolitan has an abundance of water, they may choose to activate their In-Lieu Program, where imported water is purchased in-lieu of pumping groundwater. This is a special program supported,by OCWD, MWDOC and Metropolitan, which allows some agencies to pump above the BPP without penalty of the BEA. Due to recent water shortages, this program was not utilized since 2006-07, but is being reinstated in the Spring of 2011 due to the 'wet water year. 2-12 Item 16. - 44 1113 -374- C-,ily of Huntington Beach 2010 Urban Water&,lanagement Plan Section 2 ............. ............. City Wells Within the City, groundwater for potable use is produced from ten operating wells that vary in depth from 306 feet to 996 feet, with production varying from 350 gallons per minute (gpm) to 3,400 gpm, with a total estimated system capacity of approximately 25,050 gpm as shown in Table 2.2-3. All wells are located within the City of Huntington Beach accessing the Orange County Groundwater Basin (precise locations not divulged for security purposes).

This mandate is governed by the Environmental Protection Agency (EPA) and the California Department of Public Health (CDPH) to inform customers of their drinking water quality. In accordance with the Safe Drinking Water Act, the City monitors a number of regulated and unregulated compounds in its water supply. The results from this testing were included in the,City's 2010 Annual Water Quality Report23, a copy of which was mailed to all residents of Huntington Beach. As noted in that report, the�City of Huntington Beach Public Works Department vigilantly safe-guards its water supply and, as in years past, the water delivered to City residents meets the standards required by the state and federal regulatory agencies. As mentioned earlier, the City's sources of water currently include imported water supplies and groundwater. 3.1.1 Imported Water The City receives imported water through MWDOC from Metropolitan, which receives raw water from northern California through the, SWP and the Colorado River Aqueduct. Metropolitan water is treated in accordance with potable standards at filtration plants located in Southern California. The City receives its treated imported water from the Robert B. Diemer Filtration Plant located in Yorba Linda and the Joseph Jensen Filtration Plant located in Gran'ada Hills. ' Metropolitan Water District tests and treats its water for microbial, organic, inorganic, and radioactive contaminants as well as pesticides and herbicides. Protection of Metropolitan's water system continues.to be a top priority. In coordination with its 26 member agencies, Metropolitan added new security measures in 2001 and continues to upgrade and refine procedures. Changes have included an increase in the number of water quality tests conducted each year (more than 300,000 tests are conducted for over 200 possible compounds) as,well as contingency plans that coordinate with the Homeland Security Office.24 Metropolitan also. has o.,,e of the most advanced laboratories in the country where water, quality staff performs tests, , review results, prepare collect data r v— , qual-I e reports, and research other treatment technologies. Although not required to do so, Metropolitan monitors and samples substances that are not regulated but have captured scientific and/or public interest. Metropolitan has tested for chemicals such as perchlorate, methyl tertiary butyl ether(MTBE), and chromium VI among others.

Additionally, Metropolitan's 2010 Regional Urban Water Management Plan indicates each of their major sources of water (the SWP and the CRA) has specific water quality problems. However, that Plan also notes "Metropolitan has not identified any water quality risk that cannot be mitigated. ,26 The major water quality concerns Metropolitan identified in its 2010 Regional Urban Water Management Plan include the following: (1) salinity; (2) perchlorate; (3) total organic carbon and bromide (disinfection byproduct precursors); (4) nutrients (as it relates to algal productivity); (5) arsenic; (6) uranium; (7) 'chromium VI; (8) N- nitrosodimethylamine (NDMA); and (9) pharmaceuticals and personal care products (PPCPs). Each of these constituents of concern, as well as one additional decreasing concern (MTBE)is addressed in further detail below. Salinity Water from the CRA has the highest level of salinity of all Metropolitan sources of supply, averaging 630 milligram per liter(mg/L) since 1976.27 Several actions have been taken at the state and federal level to control Colorado River salinity including (1) the International Boundary and Water Commission approval of Minute No. 242, Permanent and Definitive Solution to the International-,Problem of the Salinity of the Colorado River in 1973; (2) the U.S. President's approval of the Colorado River Basin Salinity Control Act in 1974 and (3) the formation of the Colorado River Basin Salinity Control Forum. In 1975, water quality standards and a plan for controlling salinity were approved by the EPA. In contrast, water from the SWP is significantly lower in TDS, averaging 250 mg/L over the long term in water supplied through the East Branch and 325 mg/L in water supplied through the West Branch. Because of the lower salinity, Metropolitan blends SWP water with Colorado River water to reduce the salinity in the water delivered to its customers. Metropolitan's board has adopted a salinity objective of 500 mg/L for blended imported water as defined in Metropolitan's Salinity Management Action Plan. Metropolitan estimates that the objective can be met in seven out of ten years. In the other three years, hydrologic conditions would result in increased salinity and reduced volume of SWP supplies. Perchlorate in the Colorado River Perchlorate, a contaminant of concern which can be found in rocket propellant and some types of munitions and fireworks, is believed to inhibit the thyroid's ability to process iodide and produce hormones required for normal growth and development. Perchlorate 25 MWD's October 2010 Integrated Water Resources Update can be viewed on their website at }its_%j_ti�5 .��� dh_'c.co y,'n���°cEI 2c ' a es tiorirtvater/irt)/II I"€ilORCI,nf-t.17df. 26 Per Metropolitan's 2010 Regional Urban Water Management Plan, page 4-1 which can be viewed on their website athtth %zvz�rl�.��i-dh<o.co��imwdh2o%pa��es;��o€aativatei:'RIG�MP.�RCO�` IP _'.01f).pdf 2' Ibid.,page 4-3 3-2 Item 16. s 48 IIB -378- City of Huntington Beach 20 10 Urban Water Management Plan Section 3 ............ ................ ............. ................ I has been detected at low::Ievels in the Colorado River water supply. It also has the ability to quickly dissolve and become mobile in groundwater. Perchlorate is difficult to remove from water supplies with conventional water treatment. Successful treatment technologies include naDofiltration, reverse osmosis, biological treatment, and fluidized bed bioreactor treatment. Metropolitan continues to monitor perchlorate contamination of the Colorado River. Perchlorate levels in the Colorado River have been declining in recent years, following,installation of remedial treatment systems at industrial point source locations in the Las Vegas area beginning in 1998. These efforts have reduced perchlorate levels entering the Colorado River from Las Vegas by up to 90 percent since 1998. As a result of the aforementioned aggressive clean-up efforts, perchlorate levels in Colorado River water at, Lake Havasu have decreased significantly in recent years from their peak of 9 micrograms per liter (µg/L) in May 1998. Since 2002, levels have remained less than 6 [tg/L and have typically been less than 2 [ig/L since June 2006. For comparison purposes, th'e California Department of Public Health (CDPH), on October 18, 2007, established a primary drinking water standard forperchlorate with a Maximum Contaminant Level (MCL) of 6 [tg/L. There is currently no federal drinking water standard for perchlorate, but the USEPA is in the process of making its final regulatory determination for this contaminanes In addition to the Lake Havasu site, Metropolitan also routinely monitors perchlorate at 34 locations within its system. Monitoring, data from these locations reflect non- detectable levels (below 2,,,pg/L). Metropolitan has not detected perchlorate in the SWP since monitoring began in 1997. Total Organic Carbon and Bromide (Disinfection BY-Product Precursors) SWP water supplies,contain levels of total-6rganic carbon and bromide that are a concern to Metropolitan's objective of maintaining safe drinking water supplies. When water is disinfected at treatment'p lants, certain chemical reactions can occur with these impurities that can form Disinfection Byproducts (DBP). DBPs include trihalometbanes (THMs) and haloacetic Acids (HAAs). THMs and HAAs have been found to cause cancer in laboratory animals. Inherent in any through-Delta water movement is the high organic and bromide loading imposed on the water from agricultural runoff and salt water intrusion. This poses,significant treatment challenges to the receiving end users, like Metropolitan, when if comes to avoiding problems with DBPs and the formation of THMs. With this in mind, it is imperative that the quality of SWP water delivered to Metropolitan be maintained at the highest levels possible. Water agencies such as Metropolitan began complying with new regulations to protect against the risks associated with DBP exposure in January 2002. This USEPA rule, known as the Stage I Disinfectants and Disinfection Byproducts (D/DBP) Rule, required water systems to comply with new MCLs by using appropriate treatment techniques to 28 Ibid.,page 4-8 1113 -379- Item 16. - 49 City of Hurdington Beach Section 3 2010 Urban Water Management Plan improve control of DBPs. The USEPA then promulgated the Stage 2 D/DBP Rule in January 2006, which makes regulatory compliance more challenging, because it is now determined on a locational basis, rather than on a distribution system-wide basis. To ensure the implementation of cost-effective solutions, source water quality improvements must be combined with appropriate water treatment technologies. In addressing this requirement, Metropolitan looked first at each of its five treatment plants. Two of those (Mills and Jensen) receive SWP water exclusively, while the other three (Skinner, Weymouth and Diemer) receive a blend of SWP and Colorado River water. In 2003, 2005, and 2010, Metropolitan completed upgrades to its Mills, Jensen and Skinner water treatment plants, respectively, to utilize ozone as its primary disinfectant. This ozonation process avoids the production of certain regulated disinfection byproducts that would otherwise form in the chlorine treatment of SWR water: The non-ozone plants utilizing blended water have met federal guidelines for these ,byproducts through managing the blend of SWP and Colorado River water. To maintain the byproducts at a level consistent with federal law, Metropolitan limits the percentage of SWP water used in each plant. Metropolitan's Board has also adopted plans to install ozonation at its other two blend plants (Weymouth and Diemer) in the coming years. Nutrients Increased nutrient loading (phosphorous and. 'nitrogen compounds) can lead to the formation of algal and aquatic weed growth, noxious taste and odor compounds, algal toxins and an increase in,quagga and zebra mussels and other invasive biological species. The formation or accumulation of these undesired elements has negative ramifications upon the efficiency of the water treatment and conveyance processes and inevitably leads to consumer complaints. Metropolitan has therefore taken action to minimize nutrient loading in both its SWP and CRA delivery sources as described in the following paragraphs.,. Wastewater discharges, agricultural drainage and nutrient-rich soils in the California Delta all contribute to the high levels of nutrient loading entering SWP facilities. Metropolitan and other local water agencies have therefore been working with Delta area wastewater agencies in an effort to minimize these nutrient loadings. Metropolitan also has a con-iprebensive program to monitor acid manage allg"aL growth in As source water reservoirs. In some cases, these monitoring efforts, coupled with consumer taste and odor complaints, have resulted in the need to temporarily bypass some of these reservoirs, which can have a short-term impact on available water supplies. Nutrient levels in the Colorado River are much lower than in the SWP, which allows Metropolitan to blend CRA water with SWP and thereby greatly reduce overall nutrient levels in the water supplied to its member agencies. Nevertheless, nutrient loading in the CRA system is still a concern given projected growth patterns in the Las Vegas area. For this reason, Metropolitan continues to work with entities along the Colorado River to promote good wastewater management practices, which lead to reduced phosphorous and nutrient loadings. Item 16. - 50 1 i B _38 - City of Huntington Beach 2010 Urban Water Mal7agement Plan Section 3 ..........As a result of the aforementioned monitoring and management programs, Metropolitan believes there should be no impact on future availability of water supplies due to high nutrient loadings. Arsenic in Surface Waters Arsenic, which has been linked to certain cancers and skin conditions, is a naturally occurring element found in rocks, soil, water, and air. Arsenic from these sources can enter the water supply through the natural erosion of rocks, as well as the dissolution of ores and minerals. Arsenic can also be found in wood preservatives, alloying agents, certain agricultural applications, semi-conductors, paints, dyes, and soaps. Agriculture and industrial discharges from these sources can contribute'to, elevated levels of arsenic in drinking water supplies. The MCL for arsenic in domestic water supplies was lowered to 10 gg/L (from 50 µg/L), with an effective date of January 2006 in the federal regulations, and an effective date of November 2008 in California's regulations Tor-,,,-both groundwater and usurface water supplies. Metropolitan water supplies have historically,had low levels of arsenic and have therefore not required treatment to comply with'this standard. However, some of Metropolitan's water supplies are supplemented by groundwater storage programs,which in some cases have arsenic concentrations near the MCL.' In general, these groundwater storage projects are used to supplement,s ' lies,only during low SWP allocation years. r0i upp In some instances, Metropolitan has restricted the use of such groundwater programs, thereby limiting the introduction of arsenic into the SWP. Metropolitan has also worked with one of its groundwater banking partners in constructing a pilot arsenic treatment facility to reduce arsenic enic concentrations in this;supply source. In April 2004, based on reported lung and urinary bladder cancer risk data, California's Office of Environmental Health Hazard-Assessment (OEHHA) set a public health goal (PHG) forarsenic-of 0.004 [tg/L. Monitoring results reported on CDPH's website for the period 2002-2005 showed arsenic is�ubiquitous in drinking water sources, reflecting its natural occurrence. Those results also show many sources have arsenic levels above the 10 [tg/L MCL (e.g., Southern California drinking water sources containing arsenic ov concentration ,,s' ' er 10 u /L include San Bernardino (64 sources), Los Angeles (48 9 sources), Riverside(26 sources), Orange(4 sources),and San Diego (5 sources))_29 In all cases, arsenic levels detected in Metropolitan's SWP and CRA source waters and water treatment plant effluent have been below the 10 [tg/L MCL. Nevertheless,the state detection level for purposes of reporting arsenic is 2 [tg/L. Between 2001 and 2008, arsenic levels in Metropolitan's water treatment plant effluents ranged from not detected (< 2 gg/L) to 2.9 Vg/L. For Metropolitan's source waters, levels in Colorado River water ranged from not detected to 3.5 [tg/L, while levels in SWP water ranged from not detected to 4.0 [tg/L. 29 Per CDPF1 website:http: ijov/certlic/d rink int-)w !Pa�-,cs,Arscnie.aspx-note the numbers reported on this site can change as the site is updated. 3-5 1IB -381- Item 16. - 51 City of Huntington Beach Section 3 2010 Urban Water Management Plan Uranium Uranium is a contaminant of concern in the water from the Colorado River. A 16-million ton pile of uranium mine tailings is located approximately 750 feet from the river at Moab, Utah. Rainfall seeps through this pile and contaminates the local groundwater which flows to the river. Additionally, due to the proximity of the pile to the river, there is a potential for the tailings to enter the river as the result of a catastrophic flood event or other natural disaster. Previous investigations have shown uranium concentrations within the pile near the Moab site, at levels significantly above the California MCL "of 20 picocuries per liter (pCi/L). Metropolitan has been monitoring for uranium in the'Colorado River Aqueduct and at its treatment plants since 1986 and at Lake Powell since 1998. Uranium levels measured at Metropolitan's intake have ranged from l .to 6 pCi/L, which are well below the California MCL. Conventional drinking "-water treatment, as employed at Metropolitan's water treatment plants, can remove low levels of uranium; however these processes would not be protective if a catastrophic event washed large volumes of tailings into the Colorado River. The U.S. Department of Energy (DOE) is responsible for remediating the site near Moab, which includes removal and offsite disposal of the tailings and onsite groundwater remediation. Metropolitan continues to track'progress of the remediation efforts, provide the necessary legislative support for rapid cleanup,,and 'work with Congressional representatives to support increased annual appropriations for this effort. Site remedial actions conducted since 1999,have focused on removing contaminated water from the pile and from underlying groundwater. Through 2009, over 2,700 pounds of uranium has been removed from contaminated groundwater. DOE issued its Final Environmental impact Statement in July 2005, which recommended permanent offsite disposal by rail to a disposal cell at Crescent Junction, Utah, located approximately 30 miles northwest of the Moab site. Such rail shipments began in April 2009, with over 1 million tons of mill tailings shipped to the Crescent Junction disposal cell through"March 2010. DOE anticipates shipment of an additional two million tons of tailings by September 2011 with complete removal by 2025. Another uranium-related issue, which could negatively impact CRA water supplies, began rccciving attention in 2008 as a result of renewed worldwide interest in nuclear energy and the associated increase in uranium mining claims filed throughout the western United States. Of particular interest to Metropolitan were thousands of mining claims filed near Grand Canyon National Park and the Colorado River watershed. Metropolitan has since sent letters to the U.S. Secretary of Interior to highlight source water protection and consumer confidence concerns related to uranium exploration and mining activities near the Colorado River, and advocate for close federal oversight over these activities. In 2009, Secretary of Interior Ken Salazar announced a two-year hold on new mining claims on one million acres adjacent to the Grand Canyon to allow necessary scientific studies and environmental analyses to be conducted. In 2009, H.R. 644, the Grand Canyon 3-6 Item 16. - 52 1113 -382- City of Huntington Beach 2010 Urban Water Management Plan Section 3 Watersheds Protection Act was introduced and if enacted, would permanently withdraw areas around the Grand Canyon from new mining activities. Chromium V1 Like arsenic, chromium is a naturally occurring element found in rocks, soil, plants, and animals. Chromium III is typically the form found in soils and is an essential nutrient that helps the body use sugar, protein,and fat. Chromium VI is used in a number of industrial applications including electroplating, stainless steel production, leather tanning, textile manufacturing, dyes and pigments, wood preservation and as an anti-corrosion agent. Chromium occurs naturally in deep aquifers and can also enter drinking water through industrial discharges. In drinking water, chromium VI is very stable and soluble,whereas chromium III is not very soluble. Chromium VI is the more toxic' form and is known to cause lung cancer in humans when inhaled, but the human health effects from ingestion are still a subject of conjecture. There are no current drinking water standards for chromium VI. Total, chromium (including chromium III and chromium VI) is regulated in California with an MCL of 50 gg/L. On August 20, 2009, the OEHHA released a draft PHG of 0.06 Vg/L for chromium VI in drinking water. The PHG is a health-protective, non-regulatory level that will be used by CDPH in its development of an MCL. CDPH will set the eventual MCL as close to the PHG as technically and economic-ally feasible. Metropolitan monitors chromium levels in their source and treated waters and has found all samples to be below-the State's I [tg/L detection level for purposes of reporting, with the exception of the influent to the Mills Water Treatment Plant. Metropolitan's 2010 Regional Urban Water Management Plan reports the following findings with respect to chromium VI levels found in their source and treated waters: Colorado River chromium VI levels over the past 10 years were mostly not detected (<0.03 [tg/L)but when detected, ranged from 0.03 —0.08 µg/L. • SWP chromium VI levels over the past 10 years ranged from 0.03 —0.8 Vg/L. • Treated.water chromium VI levels over the past 10 years ranged from,0.03 — 0.7 µg& The slight -increase in chromium VI levels in treated water (as compared with Colorado River water) is caused from the oxidation (chlorination and ozonation) of natural background chromium (total) to chromium VI. • Chromium VI in Metropolitan's groundwater pump-in storage programs in the Central Valley has ranged from non-detect (< 0.03 pg/L) to 9.1 µg/L with the average for the different programs ranging from 1.4 to 5.0 [tg/L. • Chromium VI has been detected in a groundwater aquifer on the site of a Pacific Gas and Electric (PG&E) gas compressor station located along the Colorado River near Topock, Arizona. However, monitoring results along the river, both 3-7 11B -383- Item 16. - 53 City of Huntington .Such Section 3 2010 Urban Water Mat7agernent Plan upstream and downstream of the Topock site, have ranged from non-detect(<0.03 Rg/L)to 0.06 µg/L. N-nitrosodimethylamine (NDMA) N-nitrosodimethylamine (NDMA) is part of a family of organic chemicals called nitrosamines. NDMA is a byproduct of the disinfection of some natural waters with chlorarnines, which are used at MWD treatment plants as a secondary disinfectant. Both the USEPA and CDPH consider NDMA to be a probable human carcinogen. While CDPH has not yet established an MCL for NDMA, they did establish a 0.01 [tg/L notification level in 1998. OEHHA also set a PHG for NDMA,of 0.003 [tg/L in 2006 and recommended that concentrations greater than 0.01 pg/L be included in a utility's annual Consumer Confidence Report. Metropolitan has monitored its source waters (at -treatment plant influents) and treated waters on a quarterly basis since 1999. Test results for NDMA in Metropolitan's system have ranged from non-detect (< 0.002 [tg/L)to"O.014 [tg/L. Metropolitan is engaged in several projects, which will lead to a better understanding of the watershed sources and occurrence of NDMA precursors in their source waters. That information can then be used to develop treatment strategies aimed at minimizing NDMA formation in drinking water treatment plants and distribution,systems. To date, special studies conducted by Metropolitan have shown the use of"advanced oxidation processes can be effective in removing NDMA. Other treatment processes such as biological, membrane, and carbon adsorption,may also be effective,but have not yet been studied. Pharmaceuticals and Personal Care Products Pharmaceuticals,and personal care products (PPCPs) are a growing concern to the water industry. Numerous studies have reported the occurrence of these emerging contaminants in treated wastewater and surface water, as well as in some finished drinking water in the United States and other countries. The sources of PPCPs in the aquatic environment can include treated wastewater, industrial discharges, agricultural run-off, and leaching from municipal landfills. There is no current evidence of human health risks frog long-term exfo-sure 1-0 the 'tow cone-ent-ations (low ng/L; parts per trillion) r of PCPs found in some drinking water. There are also no current regulatory requirements for PPCPs in drinking water. In 2007, Metropolitan implemented a monitoring program to measure the occurrence of PPCPs and other organic wastewater contaminants in its treatment plant effluents and at selected source water locations within the Colorado River and SWP watersheds. Some PPCPs were detected at very low ng/L levels, which is consistent with reports from other utilities. Metropolitan will continue to refine their analytical methods, which will lead to a better understanding of these occurrence issues and their impact on drinking water sources in California. Item 16. - 54 1113 -384- City of Huntington Beach 2010 Urban Water Management Plan Section 3 ........................................................__.......I——___............... . ......... ........... _ As noted in Huntington Beach's 2010 Annual Water Quality Report, the City has installed a Pharmaceutical Drug Disposal box in the lobby of the Huntington Beach Police Department. The Pharmaceutical Disposal Program was implemented so citizens can properly dispose of old prescription medications, and not put them in the trash or flush them down the toilet. Methyl Tertiary Butyl,Ether(MTBE) —A Decreasing Concern Although no longer a major concern, Methyl tertiary-butyl ether (MTBE) is still somewhat of a concern. MTBE was the primary oxygenate in virtually all the gasoline used in California, prior to discovering it contaminated groundwater supplies and had also been found in surface water supplies. Following that discovery, MTBE was banned in California as of December 31, 2003 and was subsequently replaced by ethanol which is now the primary oxygenate in use. CDPH has adopted a primary MCL of 13 [tg/L for MTBE based on carcinogenicity studies in animals.' MTBE has a California secondary MCL of 5 [tg/L,which was established based on taste and odor concerns'.,, MTBE was introduced into surface water bodies from the,motor exhausts of recreational watercraft. With that in mind, Metropolitan has taken steps at Diamond Valley Lake and Lake Skinner, to reduce the potential"for MTBE contamination. In 2003, Metropolitan's Board banned the use of MTBE fuel in,these reservoirs and authorized implementation of a monitoring program to detect the presence of MTBE in the lakes. In recent years, MTBE monitoring test results in source waters have remained at non-detectable levels (below 3 [tg/L). MTBE still presents ,a significant problem, to local groundwater basins. Leaking underground storage tanks and previous poor f6el handling practices at local gas stations may continue to provide`A'large S'ource,of MTBE. MTBE, which is very soluble in water and has low,affinity for so'll,particle,s,,move's quickly into the groundwater. Some local groundwater produceis,within,:MWD service area have been forced to abandon some wells,due to MTBE contamination., Unfortunately, MTBE is also resistant to chemical and microbial degradation',in water, thereby making treatment more difficult than that employed to remove other gasoline components. However, a combination of an advanced oxidation process (typically ozone and hydrogen peroxide) followed by granular activated carbon has been found to be effective in reducing the levels,of these contaminants. Although some groundwater supplies remain contaminated with this highly soluble chemical, contamination of Metropolitan's surface water supplies are no longer a problem. Improved underground storage tank requirements and monitoring procedures, as well as the phase-out of MTBE as a fuel additive, has decreased the likelihood of MTBE groundwater problems in the future. 3-9 I IB -385- Item 16. - 55 City of Huntington Beach Section 3 2010 Urban Water Mal7agement Plan Imported Water Quality Programs Metropolitan supports and is involved in many programs that address water quality concerns related to both the SWP and Colorado River supplies. Some of the programs and activities include: • Source Water Protection—Protecting the source of water supplies is of paramount importance to providing safe and reliable drinking water. CDPH requires large utilities delivering surface water to complete a Watershed Sanitary Survey every five years in accordance with California's Surface Water,,Treatment Rule, Title 22 of the California Code of Regulations. The purpose of this survey is to identify possible sources of drinking water contamination, evaluate source and treated water quality, and recommend watershed management activities to protect and improve source water quality. The most recent sanitary surveys for Metropolitan's water sources were completed in 2005 and 200630. The next Sanitary Surveys for the watersheds of the Colorado River and the SWP will report bri water quality issues and monitoring data through 261b. Metropolitan has an active source water protection program and continues to advocate on behalf of numerous SWP and Colorado River water quality protection issues. • Support of SWP Water Quality Programs — Metropolitan continues to support DWR policies and programs aimed at maintaining or'improving the quality of SWP water delivered to Metropolitan. Some,examples of this support include: o Support of the DWR policy to govern the 'quality of non-project water conveyed by the California Aqueduct. o Support of,the expansion of DWR's Municipal Water Quality Investigations Program beyond its Bay-Delta core water quality monitoring and studies to include enhanced water quality,monitoring and forecasting of the Delta and SWP. These programs are designed to provide early warning of water quality changes that will affect treatment plant operations both in the short-term (hours to weeks) and seasonally. • Water Quality Exchanges — Metropolitan has implemented selective withdrawals from the Arvin-Edison storage program and exchanges with the Kern Water Bank to improve water quality. Although these programs were initially designed to provide dry-year supply reliability, they can also be used to store SWP water during periods of good water quality and then allow for their withdrawal during times of lesser water quality, thus providing better overall water quality through dilution of SWP water deliveries. • Water Supply Security — In 2001, Metropolitan added new security measures to protect its water supply storage and conveyance facilities and continues to upgrade and refine those procedures. Changes have included an increase in the 30 Sanitary Surveys include Metropolitan's Colorado River Watershed Sanitary Survey, 2005 Update and State Water Project Contractors Authority California State Water Project Watershed Sanitary Survey, 2006 Update. Item 16. - 56 1113 -86- City of Huntington Beach 2010 Urban Water Management Plan Section 3 ............................ -------------- ............................ number of water quality tests conducted each year (Metropolitan now conducts over 300,000 analytical tests on samples collected within their service area and source waters), as well as contingency plans that coordinate with the Homeland Security Office's�multicolored tiered risk alert system. 3.1.2 Groundwater OCWD manages the City's groundwater basin and conducts a comprehensive water quality monitoring program. In 2008, OCWD collected nearly 14,000 groundwater samples from almost 700 wells. The water quality data collected ftom these wells is used to monitor the impacts of basin extraction, determine the eff6ctiveness of the seawater intrusion barriers, assess the impacts of historic and current land uses, and serve as a sentinel or early warning of emerging contaminants of concern. 31 OCWD's water quality monitoring programs are broadly classified into three categories; (1) compliance with permits and drinking water regulations; (2) OCWD Board approved projects for research and other purposes; and (3) basin management. OCWD's extensive 0j groundwater quality management program allows the agency ency to address current issues and develop strategies to anticipated and resolve future issues. OCWD's July 2009 Groundwater Management Plan Update has,a section devoted solely to groundwater quality management. The groundwater quality issues facing OCWD and the City and the programs implemented to addre,ss those=,issues are summarized in the following sections, which have been extracted from the July 2009 Groundwater Management Plan Update. Area's of specific,concern include: (1) Salinity; (2) Nitrates; (3) Volatile Organic Contaminants; (4) MTBE; (5) NDMA; (6) 1,4-Dioxane; (7) Perchlorate; (8)Emerging,Contaminants; and(9) Colored Groundwater. Salinity High concentrations I of, salts can contaminate groundwater supplies, constrain implementation of water recycling projects, and cause other negative economic impacts such as the need for increased water treatment by residential, industrial and commercial -sers. Sources of salinity in water used to recharge the groundwater basin include Santa Ana River water, imported water, shallow groundwater within Orange County, seawater migrating into the' basin, precipitation, and legacy contamination from historical agricultural operations. Water treatment plants, also referred to as desalters, have been built in Riverside and San Bernardino Counties to reduce salinity levels in water supplies. Within Orange County, desalters in Tustin and Irvine are reducing salinity levels in the groundwater basin. The GWR System provides a dependable supply of low salinity water that is expected to reduce the basin salt imbalance by approximately 47,000 tons/year. 31 Orange County Water District, Groundwater Management Plan,July 2009 Update available at: 3- 11B -387- Item 16. - 57 City of Huntington Beach Section 3 2010 Urban Water Management Plan Nitrates Nitrates are one of the most common and widespread contaminants in groundwater supplies. Elevated levels of nitrates in soil and water supplies originate from fertilizer use, animal feedlots and wastewater disposal systems. OCWD conducts an extensive program to protect the basin from nitrate contamination, including operating 450 acres of wetlands in the Prado Basin to naturally remove nitrate before the water enters the District's recharge facilities. The early agricultural practices with OCWD contributed to the high concentrations of nitrates in the shallow groundwater. Although nitrates are present throughout the basin, only a small number of areas exceed the MCL. Ninety-eight percent of the drinking water wells pumping from the Orange County groundwater basin meet the nitrate drinking water standard. The two percent that do not meet the nitrate standard are treated to reduce nitrate levels prior to the water being served to customers. Volatile Organic Compounds (VOC) VOCs in groundwater come from a number of sources. From the late 1950s through early 1980s, VOCs were used for industrial degreasing in metals and electronics manufacturing. Other common sources include paint thinners and dry cleaning solvents. VOC contamination is found in several locations in the basin. In 1985, a contamination site was discovered beneath the former El Toro MCAS. Monitoring wells at the El Toro site installed by the U.S. Navy and OCWD delineated a one-mile wide by three-mile long VOC plume, comprised primarily of trichloroethylene (TCE). Beneath the former Air Station, VOC contamination was primarily found in the shallow groundwater up to 150 feet below the ground surface. Off-base, to the west, the VOC plume is in deeper aquifers from 200 to 600 feet deep. Another VOC contamination site was found in portions of the shallow aquifer in the northern portion of the Orange County in the cities of Fullerton and Anaheim. Although not directly used for drinking water supplies, groundwater in the shallow aquifer eventually flows into the deeper principal aquifer, which is used for potable water supplies. To date, two city of Fullerton production wells have been removed from service and destroyed due to VOC contamination in that area. Currently, there are no production wells in that area that extract water from the shallow aquifer. Elevated concentrations of perchloroethylene (PCE), TCE, and perchlorate were detected in IRWD's Well No. 3, located in Santa Ana. OCWD is currently working with the Regional Board and the California Department of Toxic Substances Control to require aggressive cleanup actions at nearby sites that are potential sources of the contamination. No City of Huntington Beach wells have been impacted by VOC contaminants. Item 16. - 58 1111 -s118- City of Huntington Beach, 20 10 Urban Water Managem ent Plan Section 3 .......... ............ Methyl Tertiary-Butyl Ether(MTBE) During the 1980s, gasoline hydrocarbons of greatest risk to drinking water were benzene, toluene, ethylbenzene, and xylenes, collectively known as BTEX chemicals. Although leaking underground fuel tanks were identified throughout the basin, these chemicals typically were degraded by naturally-occurring microbes that allowed clean up by natural attenuation or passive bioremediation. As mentioned in previous sections of this Plan, MTBE, a more recent additive to gasoline aimed at reducing air pollution contributed to the widespread contamination of some groundwater supplies' MTBE is a serious threat to groundwater quality because it sorbs weakly to soil and does not readily biodegrade. The greatest source of contamination comes from releases from underground fuel tanks. Drinking water wells in the basin are tested annually for VOC analytes including MTBE. i OCWD continues to work with local water agencies such as the City-, to monitor for MTBE and other fuel-related contaminants to identify areas that may have potential underground storage tank problems and releases resulting in groundwater contamination. 9 N-nitrosodimethylamine (NDMA) OCWD monitors NDMA levels in the groundwater basin. As previously noted, the California Notification Level for NDMA is-. 0.01 pg/L. OCWD has found the concentration of NDMA in the Santa Ana River" at Imperial Highway to be typically less than 0.002 [tg/L. At,,OCWD's GWR System treatment facility in Fountain Valley, NDMA concentrations are maintained below,California's Notification Level through a combination of source, control measures, reverse osmosis treatment, and advanced oxidation treatment using ultraviolet,light and hydrogen peroxide. 1,4-Dioxane A suspected human carcinogen, fA-dioxane, is used as a solvent in various industrial processes such as the manufacture of adhesive products and membranes and may occur in consumer products such as detergents, cosmetics,pharmaceuticals, and food products. In 2002, OCWD detected elevated levels of 1,4-dioxane in nine production wells,exceeding the California Action Level. These wells were temporarily shutdown with a 'loss of')4 mgd of water supply. Further investigation traced the contaminant to one industrial discharger that was discharging 1,4-dioxane into wastewater collected by OCSD. This discharge was affecting water that was treated by Water Factory-21 and injected into the Talbert Seawater Barrier. When the discharger voluntarily ceased discharge of 1,4- dioxane, concentrations declined. Additional monitoring data showed low concentrations, the CDPH determined that the water was not a significant risk to health, and the wells were returned to service. 3-13 1113 -389- Item 16. - 59 City of Huntington Beach Section 3 20 10 Urban Water Management Plan .............----------.......... Perchlorate Perchlorate has been detected at wells distributed over a large area of the groundwater basin. Based on data from 217 active production wells collected from 2006 through 2009 and a perchlorate detection limit of 2.5 micrograms per liter, only seventeen percent of the wells had detectable concentrations of perchlorate. For those wells with detectable amounts of perchlorate, 89 percent had perchlorate concentrations below the California primary drinking water standard of 6 micrograms per liter. Four of the 217 active production wells had perchlorate concentrations greater than 6 micrograms per liter. It is important to note that water delivered for municipal purposes'meets the primary drinking water standard. Groundwater from production wells that have perchlorate concentrations over the primary drinking water standard is treated to reduce the perchlorate concentration below the primary drinking water standard prior to delivery for municipal usage. Sources of perchlorate in the groundwater basin may include: • Fertilizer application; • Water imported from the Colorado River (through the use of Colorado River water for groundwater recharge, Irrigation, or wafer supplies that impact the groundwater basin through onsite,wastewater disposal systems); • Discharges from industrial or military sites that used, disposed of, or stored perchlorate; and • Naturally occurring perchlorate(e.g.,perchlorate in rainfall). OCWD's ongoing monitoring program continues to assess the distribution of perchlorate in the groundwater basin and the change in concentration over time. OCWD will also continue to work with its groundwater producers in alleviating perchlorate concerns. Emerging Contaminants Pharmaceuticals, personal care products, and endocrine disruptors are considered emerging environmental contaminants. "There are water quality concerns associated with these emerging contaminants because of their wide spread use among the population and their impact on human health because of exposure to low doses over long periods of time. OCWD is aware of these contaminants and is working with DPH to track and report their concentrations in the groundwater. OCWD advocates the following general principles as water suppliers and regulators develop programs to protect public health and the environment from adverse effects of these emerging contaminants: • Monitoring should focus on constituents that pose the greatest risk; 3-14 Item 16. - 60 1113 -390- City of Huntington Beach 2010 Urban Water Management Plan Section 3 • Constituents that are prevalent, persistent in the environment, and may occur in unsafe concentrations should be prioritized-, • Analytical methods to detect these constituents should be approved by the state or federal government; • Studies to evaluate the potential risk to human health and the environment should be funded by the state or federal government; and • The state and federal government should encourage programs to educate the public on waste minimization and proper disposal of unused,pharmaceuticals. OCWD is committed to (1) track new compounds of concern; (2) research chemical occurrence and treatment; (3) communicate closely with. CDPH on prioritizing investigation and guidance; (4) coordinate with OCSD,, upper watershed wastewater dischargers, and regulatory agencies to identify sources and reduce contaminant releases; and (5) keep groundwater producing agencies such as Huntington Beach-well informed on emerging issues. Colored Groundwater Colored water is found in deep aquifers (600-2000 feet) over a broad region of Orange County. Natural organic material from ancient redwood- forests,and peat bogs gives the water an amber tint and a sulfur odor. Although colored water is of very high quality, negative aesthetic qualities, its color and odor, require treatment before use as drinking water. The total amount of colored groundwater is es'timated to be over one million acre feet, perhaps as much as several million acre feet. Economic constraints pose challenges to developing colored, water supplies as the water needs to be treated to remove the color and odor. Costs depend on the water quality (color and other parameters) and the type and extent of required treatment. An additional factor that must' be considered is the impact of water levels in the clear zone compared to water levels in the deeper aquifers with colored water. Monitoring wells reveal a correlation of clear/colored zone water level fluctuations, indicating a fairly strong hydrologic-connection between the two ZODeS in some areas of the basin- Three facilities currently treat colored groundwatc.- in Orange County. Mesa Consolidated Water District (MCWD) has operated an ozone oxidation treatment facility since 1985 at its Well No. 4 site. In 2001, MCWD opened its Colored Water Treatment Facility (CWTF) using ozone treatment to produce 4,000 gallons per minute. The third facility is the Deep Aquifer Treatment System (DATS), a treatment facility using nano- filtration membranes operated by IRWD since 2002. This facility purifies 7.4 mgd of colored water. I I B -391- Item 16. - 61 City of Huntin lon Beach Section 3 2010 Urban Water 111, nagem nt Plan The City's Well No. 8 falls within one of the County's colored water zones. As a result, this well has been out of production for several years. However, the City is currently pursuing a project to use Well No. 8 colored water and urban water runoff water for irrigation of various parks along Goldenwest Street. Groundwater Quality Protection Policy In recognition of the serious threat posed by groundwater contamination, OCWD adopted the Groundwater Quality Protection Policy in May 1987. The objectives of the policy are to: • Maintain groundwater quality suitable for all existing and potential beneficial uses; • Prevent degradation of groundwater quality; • Assist regulatory agencies in identifying the sources of contamination to assure cleanup by the responsible parties; • Maintain or increase the basin's usable storage capacity; and • Inform the general public, regulatory agencies and Producers of the condition of the groundwater basin and of water quality problems as they are discovered. The following eight specific programs were established to achieve these objectives: 1. Water quality monitoring of surface and groundwater; 2. Identification, interim containment, and cleanup of contamination; 3. Coordinated operation;with regulatory agencies; 4. Control of toxic,residuals; 5. Hazardous waste management planning; 6. Dissemination of technical information; 7. Public disclosure; and 8. Groundwater protection evaluation. A key component of the policy describes circumstances under which OCWD will undertake contamination cleanup activities at District expense. This becomes necessary when contamination poses a significant threat and the party responsible for the contamination cannot be identified, is unable to clean up the contamination, or is unwilling to clean up the contamination. When appropriate to protect water quality in the basin, OCWD can also provide financial incentives for Producers to pump and treat groundwater that does not meet drinking water quality standards. 3-16 Item 16. - 62 1113 -392- City of Huntington Beach 2010 Urban Water Management Plan Section 3 ............. ................. ------- ...............__........ .........-------- Groundwater Quality Improvement Projects In addition to the Groundwater Quality Protection Policy, OCWD has also undertaken a number of specific projects aimed at improving water quality in the basin. Information on these projects has been extracted from OCWD's July 2009 Groundwater Management Plan Update and MWD6c's 2010 RUWMP and is presented below. I. North Basin Groundwater Protection Project (NBGPP) — The NBGPP protects drinking water supplies and the beneficial use of groundwater. This project consists of five wells, which have been constructed to specifically remove and contain contaminated groundwater in the shallow aquifer. Additional extraction wells may be needed. OCWD will also construct pipelines to bring the contaminated groundwater to a centralized treatment plant where the contaminants will be removed. The purified water will then be re-injected back into the shallow aquifer. OCWD has initiated legal action against the parties responsible for contamination to seek cost recovery so that the public does not have to pay for this project. 2. South Basin Groundwater Protection Project (SBGPP) — The SBGPP is similar in nature to the NBGPP,but protects drinking water supplies in the south part of the Orange County groundwater basin. OCWD"constructed six tri-nested monitoring wells to investigate the extent,of VOC-contaminated groundwater in the Shallow Aquifer. Delineation of the contaminated groundwater will likely involve more than one phase of investigation." If "hot spots" or contaminated plumes are `identified, the SBGPP may include comprehensive remediation systems to contain and remove the contamination similar to the NBGPP or localized interim remedial measures. 3. MTBE, Remediation — In 2003, OCWD filed suit against numerous oil and petroleum-related companies that produce, refine, distribute, market, and sell MTBE and other oxygenates. The suit seeks funding from these responsible parties to pay for the investigation, monitoring, and removal of oxygenates from the basin. Treatment technologies used to remove MTBE from groundwater include,granular activated carbon (GAC) or advanced oxidation. Depending upon site-specific requirements, a treatment train of two or more technologies in series may be appropriate. 4. Irvine Desalfer—The Irvine Desalter was built in response to the 1985 discovery of VOCs beneath the former El Toro MCAS and the central area of Irvine. The plume of improperly disposed cleaning solvents migrated off base and threatened the main basin. IRWD and OCWD cooperated in building production wells, pipelines, and two treatment plants, both of which are now owned and managed by IRWD. One plant removes VOCs by airstripping and vapor-phase carbon adsorption with the treated water used for irrigation and recycled water purposes. A second plant treats groundwater outside the plume to remove excess nitrate and TDS concentrations using RO membranes for drinking water purposes. Combined production of the Irvine Desalter wells is approximately 8,000 AFY. 3-117 11B -393- Item 16. - 63 City of Hurdington Beach Section 3 2010 Urban W-�,iter Management Plan ............. . -- 5. Tustin Desalters — Tustin's Main Street Treatment Plant has operated since 1989 to reduce nitrate levels from the groundwater produced by Tustin's Main Street Wells Nos. 3 and 4. The untreated groundwater can undergo either RO or ion exchange treatment. The RO membranes and ion exchange unit operate in a parallel treatment train. Approximately I mgd is bypassed and blended with the treatment plant product water to produce up to 2 mgd or 2,000 AFY. During fiscal year 2007-08, 55,700 pounds of nitrate were removed at this treatment plant. The Tustin Seventeenth Street Desalter began operation in 1996 to reduce high nitrate and TDS concentrations from the groundwater pumped by Tustin's Seventeenth Street Wells Nos. 2 and 4 and Tustin's Newport well. The desalter utilizes two RO membrane trains to treat the groundwater. The treatment capacity of each RO train is I mgd. Approximately I mgd is bypassed and blended with the RO product water to produce up to 3 mgd or approximately 3,000 AFY. During fiscal year 2007-08, 154,800 pounds of nitrate were removed at this treatment facility. 6. Garden Grove Nitrate Removal — The,Garden Grove Nitrate Removal Project was a blending project utilizing two wells to'meet the MCL for nitrate. Garden Grove Well No. 28, containing high nitrate concentrations, was blended with water from Well No. 23. The<blending project operated from 1990 to 2005, when it was shut down. The City of Garden Grove is currently retrofitting Well 28 with a variable frequency drive and intends to reinstate the blending operation in 2012. 7. River View Golf'Course — VOC cqntaminatiop' ,,;originating from an upgradient source, was discovered in a well owned by River View Golf Course, located in the City of Santa Ana. The well was used for drinking water but was converted into a supply for golf course irrigation due to the contamination. Continued operation of the'well helps to remove VOC contamination from the basin. 8. Colored Water Treatment Mesa Consolidated Water District had been operating an ozone oxidation treatment plant to remove the color from groundwater pumped from Well No. 6 and Well No. 11. Due to an increase in color and bromide in the source water, Mesa has embarked on a project to replace the ozone and biological filtration treatment with nanofiltration membrane treatment and increase the capacity from 5.8 MGD to 8.6 MGD. Design and construction.of this replacement and expansion project began in September 2009 and is anticipated to be completed in April Of 2012. IRWD's Deep Aquifer Treatment System (DATS) removes color from deep aquifer groundwater. A total of 8 mgd of colored groundwater is pumped from two wells (IRWD C8 and C9) to the DATS plant. Nanofiltration (NF) membranes remove color and organics. Three NF trains each produce 2.44 mgd at a recovery rate of 92 percent. The high quality NF product water is degasified, disinfected, and pumped into the Dyer Road Wellfield pipeline for potable use resulting in 7.4 mgd added to the drinking water system. The highly colored NF concentrate is sent to disposal by OCSD. 3-1 tS Item 16. - 64 1113 -394- City of Huntinglon Beach 2010 Urban Water Management Flan Section 3 The colored water treatment projects operated by MCWD and IRWD provide benefit beyond the production of water supply. The aquifers with colored water are generally deeper than the primary clear water production zones, and upward vertical migration of the colored water into the clear water aquifers has been observed. Upward migration can impair water quality in the clear water zones. A large groundwater level difference between the colored water aquifer and clear water aquifers exacerbates this situation. By pumping from the colored water aquifer, the MCWD and IRWD projects reduce the groundwater level in the colored water aquifer, thus reducing the vertical migration of colored water into the clear water aquifers. x 3.2 WATER QUALITY EFFECT ON WATER MANAGEMENT STRATEGIES AND SUPPLY RELIABILITY The previous section summarized the general water quality issues:of Metropolitan's imported water and OCWD's groundwater supplies. The same water quality concerns apply to the City's water. Similar to Metropolitan and OCWD, the City-prepared an assessment of the City's drinking water in DecernberM2002. The groundwater sources were found to be most vulnerable to possible contamination from dry cleaners, electrical/electronic manufacturing, gas, stations, known contaminant plumes, metal plating/finishing/fabricating, military installations, and plastics/synthetic producers.32 The City continues to monitor its groundwater wells for the first indication of problems as part of their water management strategy. The City has not experienced":any significant,water quality problems in recent years and does not anticipate any significant changes in its available water supply due to water quality issues in the future due in large part to the mitigation actions undertaken by Metropolitan and OCWD as described earlier.."', x ''City of Huntington Beach,2009 Water Quality Report. 1113 -395- Item 16. - 65 City of Huntington Beach Section 3 2010 urban Water Management Plan This page intentionally left blank. 3-20 Item 16. - 66 11B -96- City of Huntington Beach 2010 Urban Water Management Plan Section 4 ..............I--...., -................... 4 WATER RELIABILITY PLANNING 4.1 RELIABILITY OF WATER SUPPLIES This section provides a description of the efforts of Metropolitan, MWDOC, OCWD and the City of Huntington Beach in securing an adequate and reliable regional water supply. This section also includes further discussion of these agencies and their roles in water supply reliability, and the near and long-term efforts they are involved with to ensure future reliability of water supplies to the City and the region as a whole. The Southern California region faces a challenge in satisfying,demands and securing firm water supplies. Increased environmental regulations and the competition for water from outside the region have resulted in reduced suppliesxof imported water. Continued population and economic growth generally leads to increased regional water demands, which results in larger demands on local supplies. Reliability is a measure of a water system's expected' success in managing naging water shortages. Good reliability planning requires accurate answersto the following questions: 1. What are the expected frequency,Uand severity of shortages? 2. How will additional water management,measures likely affect the frequency and severity of shortages? 3. How will available contingency measures reduce the impact of shortages when they occur? The reliability of the City's water supply is currently dependent on the reliability of both the groundwater managed by,:QCWD and the imported water supplies managed by Metropolitan and,, delivered by the Municipal Water District of Orange County (MWDOC). Despite the ongoing regional water supply challenges, the goals and statutory"mission of these lagencies, are'to identify and develop projects to meet regional water demands. State funding has been made available, through California voters' approval, to increase reliability of state water supplies. In March 2000, California voters approved Proposition 13, which authorized the State to issue $1.97 billion of its general obligation bonds for water projects. Additional lly, California voters approved Proposition 50 in November 2002 and Proposition 84 in November 2006, which authorized the issuance by the State of $3.4 billion and $5.4 billion, respectively, of general obligation bonds for water projects. Types of water rojects eligible for funding under Propositions 13, 50, and 84 include water conservation groundwater storage, water treatment, water quality, water security and Colorado River water management projects. 41 1113 -397- Item 16. - 67 City of Huntington Beach Section 4 2010 Urban Water Management Plata 4.1.1 Regional Agencies and Water Reliability Metropolitan Water District of Southern California (Metropolitan) Metropolitan was formed in the late 1920's with the primary goal of providing reliable water supplies to meet the water needs of its service area at the lowest possible cost. Collectively, charter members recognized the limited water supplies available within the region, and realized that continued prosperity and economic development of Southern California depended upon the acquisition and careful management of an adequate supplemental water supply. This foresight made the continued development of Southern California possible. Metropolitan acquires water from Northern California via the State Water Project (SWP) and from the Colorado River via the Colorado River Aqueduct (CRA)4o supply water to most of Southern California. As a wholesaler, Metropolitan has no retail customers, and distributes treated and untreated water directly.to its 26 member agencies. One such member agency is the Municipal Water District'of Orange County, of which the City of Huntington Beach is a member agency. Through a series of Integrated Resources Plans initiated in 1996 and most recently updated in 2010, Metropolitan has worked, toward identifying and developing water supplies to provide 100 percent reliability. Due to competing,needs and uses for all of the water sources and regional water operational. issues, Metropolitan undertook a number of planning processes: the Integrated Resources Planning (IRP) Process, the Water Surplus and Drought Management (WSDM) Plan, the Strategic Planning Process, the Report on Metropolitan Water Supplies: A Blueprint for Water Reliability, and most recently, the October 2010 IRP update and the.November 2010 Regional Urban Water Management Plan. Combined, these documents provide a framework and guidelines for optimum future water planning. The reliability and operational issues related to Metropolitan's various sources of supply are discussed in detail by major source in the subsequent subsections of this Urban Water -Management Plan. Metropolitan provides imported water supplies to the City through the City's Metropolitan member agency, MWDOC. Metropolitan is the wholesale water agency that serves„supplemental imported water from northern California through the State Water Project(SWP) and the Colorado River to 26 member agencies located in portions of Los Angeles, Orange, Riverside, San Bernardino, San Diego, and Ventura Counties, of which MWDOC is one. The construction of the SWP was authorized by the State Legislature in 1951. Eight years later, the Legislature passed the Burns-Porter Act, which provided a mechanism for bonds to be issued to pay for the construction of certain portions of the SWP facilities. The California Department of Water Resources (DWR) has entered into contracts with water districts and regional agencies (SWP Contractors) specifying the amount of SWP water to be delivered to each SWP Contractor. Each SWP Contractor was provided with a contract amount and capacity rights to the SWP aqueduct and storage system in return Item 16. - 68 1113 -98- City of Huntington Beech 2010 Urban Water Management Plan Section 4 for payments intended to cover operation and maintenance, bondholder obligations, and repayment of moneys loaned from the California Water Fund. DWR water supply contracts contemplate SWP eventual delivery of 4.2 million AFY to 29 SWP Contractors. Although the SWP is not fully constructed and cannot yet deliver the full 4.2 million AFY in all years, the SWP has fully met SWP Contractors' water needs twelve out of the 17 years following the end of a six year drought in 1992. The dry years include 1994, 2001, and 2007 through 2009. Of SWP water deliveries, about 70 percent is delivered to SWP urban contractors and about 30 percent is delivered to SWP agricultural contractors. Kern County Water Agency and Metropolitan are the largest Contractors with DWR for SWP water.33 From a statewide perspective, the maximum capacity of the overall SWP,transportation system is generally limited by the capacity of the system pumps. The capacity of the California Aqueduct is 10,300 cubic feet per second (cfs} at its northern end, and 4,480 cfs below the Edmonston pumping plant (1,000 cfs equates to approximately 82.6 acre- feet per hour, 1,983 acre-feet per day and 724;000 AFY). If these transportation rates were maintained for a full year, they would result in the,transport of approximately 7.2 million acre-feet near the Delta and 3.2 million acre-feet to users, in Southern California 34 Demand can have a significant effect upon the reliability of a water system. For example, if the demand occurs only three months in the summer, a water system with a sufficient annual supply but insufficient water storage may not be able to reliably meet the demand. If, however, the same amount of demand is distributed over the year, the system could more easily meet the demand because the need for water storage is reduced. Because the City of Huntington Beach overlies the Orange County Groundwater Basin and can utilize the Basin to smooth out seasonal peaks, its imported water reliability is enhanced. Metropolitan's SWP imported water is stored at Castaic Lake on the western side of their service area and at Silverwood Lake near San Bernardino. Metropolitan water imported from the Colorado River via the CRA is stored at Diamond Valley Lake and Lake Mathews in Riverside County. Metropolitan member agencies receive imported-water at various delivery points along their system, and pay for it at tiered and/or uniform rates established by the Board, depending on the class of service. Metropolitan has recently increased its ability to supply water, particularly in dry years, through implementation of storage and transfer programs. Metropolitan's 26 member agencies deliver to their customers a combination of groundwater, local surface water, recycled water and imported water purchased from Metropolitan. For some member agencies, Metropolitan supplies all the water used within their service area, while others obtain varying amounts of water from Metropolitan 33 See,generally DWR Bulletin No. 132-06 and latter supplements to Bulletin No. 13;report available at this link:http: ,AAA v.water.ca. ov_'ss aolbulletim.cim . ,4 DWR, Bulletin No. 132-05,December 2006;report available at this link: e._Neater.ca-L,wv;'swpa(,,"1)ullenn.cfm 4-3 11B -399- Item 16. - 69 City of Huntington Beach Section 4 2010 Urban Water Management Plan .......... to supplement local supplies. Metropolitan has provided between 45 and 60 percent of the municipal, industrial and agricultural water used in its service area.'5 Historical water demands in the Metropolitan service area increased from 3.14 million acre feet (MAF) in 1980 to 3.93 MAF in 1990. Total retail water demand is projected to grow from its current 4.03 MAF in 2010 to a projected 4.27 MAF in 2035.36 For the Orange County service area, according to Metropolitan, demands are projected to increase approximately 2.1 percent between 2010 and 2035.37 Table 4.1-1 shows the historic and projected total retail water demands for Metropolitan's Orange County service area. The water demand forecasts account for water savings resulting from plumbing codes, price effects, and actual and projected implementation of water conservation Best Management Practices as mandated by Senate Bill x7-7.38 Table 4.1-1 Total Retail Water Demand in Metropolitan's Service Area for Orange County (includes Municipal and Industrial, and Agriculture in AF) al "J_,. x 'Interpolated P cte( 202( J11201 0-: ',!, 20 202��'��"'[` 2035 0 0 5 'S 7v 577,000 660,000 629,000 624,000 -651,000 634,000 635,000 1 637,000 637,000 Source: November 2010 Regional Urban Water Management Plan for the Metropolitan Water District of Southern California,Table A.1-5 Colorado River Aqueduct(CRA) The Colorado River was -Metropolitan's original source of water after the agency's establishment in 1928. Metropolitan'bas a legal entitlement to receive water from the Colorado River under-a permanent service contract with the U.S. Secretary of the Interior. Water from'the Colorado River or its tributaries is also available to other users in California, as well as to users in the states of Arizona, Colorado, Nevada, New Mexico, Utah, and Wyoming (the "Colorado River Basin States"), resulting in both competition and the need for cooperation among these holders of Colorado River entitlements. In addition,°undcr a 1944 treaty, NIexlco has an allotm, cni of 1.5 million acre-feet of Colorado River water annually, except in the event of extraordinary drought or serious accident to the delivery system in the United States, when the water allotted to Mexico can be curtailed. Mexico can also schedule delivery of an additional 200,000 acre-feet of Colorado River water per year if water is available in excess of the requirements in the United States and the 1.5 million acre-feet allotted to Mexico. 35 Metropolitan Water District of Southern California,Urban Water Management Plan,November 2010, page 1-6;Plan can be accessed at this link: 31 Ibid.,Table A.1-5 37 Ibid.,Table A.1-5 31 Ibid.,Table A.1-5 41 Item 16. - 70 1113 -400- City of Mintington Beach 2010 Urban Water Management Man Section 4 The Colorado River Aqueduct, which is owned and operated by Metropolitan, transports water from the Colorado River approximately 242 miles to its terminus at Lake Mathews in Riverside County. After deducting for conveyance losses and considering maintenance requirements, up to 1.2 million acre-feet of water a year may be conveyed through the CRA to Metropolitan's member agencies, subject to availability of Colorado River water for delivery to Metropolitan as described below. California is apportioned the use of 4.4 million acre-feet of water from,the Colorado River each year plus one-half of any surplus that may be available for use collectively in Arizona, California and Nevada. In addition, California has historically been allowed to use Colorado River water apportioned to, but not used by, Arizona and Nevada when such supplies have been requested for use in California. Under the 1931 priority system that has formed the basis for the distribution of Colorado River water made available to California, Metropolitan holds the fourth priority right to 550,000, acre-feet per year. This is the last priority within California's basic apportionment of 4.4 million acre-feet. In addition, Metropolitan holds the fifth priority right -to 662,000 acre-feet-of water, which is in excess of California's basic apportionment. Until 2002, Metropolitan had been able to take full advantage of its fifth priority right as a result of the availability of surplus water and apportioned-but unused water. However, Arizona and Nevada increased their use ofr water from the,Colorado River, leaving no unused apportionment available for California"since the late T990s. In addition, a severe drought in the Colorado River Basin has reduced,storage in system reservoirs,resulting in no surplus water being available since 2062. Prior to,2002, Metropolitan could divert over 1.2 million acre-feet in any year, but since that time, Metropolitan's deliveries of Colorado River water varied from a low of 535,000 acre-feet in 2006 to a projected high of 1,150,000 acre-feet in_201039 Metropolitan has .taken steps, to augment,its share of Colorado River water through agreements with other agencies that have rights to use such water. Under a 1988 water conservation agreement(the "1988.Conservation Agreement") between Metropolitan and the Imperial,Irrigation District (IID), IID has constructed and is operating a number of conservation"projects that are currently conserving 105,000 acre-feet of water per year. In 2007, the conserved water augmented the amount of water available to Metropolitan by 85,000 acre-feet and; by prior agreement, to the Coachella Valley Water District (CVWD)by 20.,000"acre-feet.40 In 1992, Metropolitan entered into an agreement with the Central Arizona Water Conservation District (CAWCD) to demonstrate the feasibility of CAWCD storing Colorado River water in central Arizona for the benefit of an entity outside of the State of Arizona. Pursuant to this agreement, CAWCD created 80,909 acre-feet of long-term storage credits that may be recovered by CAWCD for Metropolitan. Metropolitan, the Arizona Water Banking Authority, and CAWCD executed an amended agreement for 39 Ibid.,Table A.2-1 411 Ibid, Page A.3-4 4-5 1113 -401- Item 16. - 71 City of Huntington Beach Section 4 2010 Urban !!{later Management Plan recovery of these storage credits in December 2007. In 2007, 16,804 acre-feet were recovered. Metropolitan requested 25,000 acre-feet be recovered in 2008, and expects to request the balance of the storage credits over the next several years. Water recovered by CAWCD under the terms of the 1992 agreement allows CAWCD to reduce its use of Colorado River water, resulting in Arizona having an unused apportionment. The Secretary of the Interior is making this unused apportionment available to Metropolitan under its Colorado River water delivery contract. In April 2008, Metropolitan's Board authorized the expenditure of$28.7 million to join the CAWCD and the Southern Nevada Water Authority (SNWA) in funding the construction of a new 8,000 acre-foot off-stream regulating reservoir near Drop 2 of the All-American Canal in Imperial County. The Drop 2 Reservoir,is expected to save up to 70,000 acre-feet of water per year by capturing and storing water'that would otherwise be lost. In return for its funding, Metropolitan received 100,000 acre'feet of water that is stored in Lake Mead until recovered, with annual delivery of up to'34,000 acre-feet of water through 2010 and up to 25,000 acre-feet between 2011 and 2036. Besides the additional water supply, the new reservoir will add to the flexibility of Colorado River operations. Metropolitan and the Palo Verde Irrigation District (PVID) signed the program agreement for a Land Management, Crop Rotation and Water Supply Program in August 2004. This program provides up to 118,000 acre"-feet of water available to Metropolitan in certain years. The term of the program is '35 years., Fallowing of approximately 20,000 acres of land began on January 1,�2005. In 2005, 2006, 2007, 2008 and 2009 approximately 108,700, 105,500, 72,300, 94,300 and 102,200 acre-feet, respectively, of water were saved through these programs.41 With Arizona's and Nevada's increasing use of their respective apportionments and the uncertainty of continued Colorado River surpluses, in 1997 the Colorado River Board of California, in consultation with Metropolitan, IID, PVID, CVWD, the Los Angeles Department of Water and Power and the San Diego County Water Authority (SDCWA), embarked on the development of a plan for reducing California's use of Colorado River water to its basic apportionment of 4.4 million acre-feet when use of that basic allotment is necessary (California Plan). In 1999, IID, CVWD, Metropolitan and the State of California agreed to a set of Key Terms aimed at managing California's Colorado River supply. These Key Terms were incorporated into the Colorado River Board's May 2000 California Plan that proposed to optimize the use of the available Colorado River supply through water conservation, transfers from higher priority agricultural users to Metropolitan's service area and storage programs. To implement these plans, a number of agreements have been executed. One such agreement, the Quantification Settlement Agreement (QSA), is a landmark agreement signed by the four California Colorado River water use agencies and the U.S. Secretary of the Interior, which will guide reasonable and fair use of the Colorado River by 41 Ibid.page A.3-7 4-6 Item 16. - 72 11B -402- City of Huntington Beach 2010 Urban Water Management Plan Section 4 --------------- ........... California through the year 2037. The QSA was authorized in October 2003 and defined Colorado River water deliveries to the four California agencies as well as facilitated transfers from agricultural agencies to urban users. The QSA is a critical component of California's Colorado River Water Use Plan. State Water Project(SWP) The SWP is owned and operated by the California Department of Water Resources. The reliability of the SWP impacts Metropolitan's member agencies' ability to plan for future growth and supply. On an annual basis, each of the 29 SWP_contractors, including Metropolitan, request an amount of SWP water based on their.anticipated yearly demand. In most cases, Metropolitan's requested supply is equivalent to its full Table A Amount,42 currently at 1,911,500 AFY, and in certain wetter years 'additional supply may be made available. The full Table A amount is defined as the maximum amount of imported water to be delivered and is specified in the contract between the DWR and the contractor. After receiving the requests, DWR assesses the amount of water supply available based on precipitation, snow pack on northern California watersheds, volume of water in storage, projected carry over storage, and Sacramento,-San Joaquin Bay Delta regulatory requirements. Due to the uncertainty in water supply, contractors are not typically guaranteed their full Table A Amount,,but instead, are,allocated a percentage of that amount based on the available supply. Table 4-1-2 lists the historical SWP deliveries to Metropolitan and the delivery's percentage compared to the full Table A amount. Once the percentage is set early in the water year, the agency, can count on that amount of supply or more in the coming year. The percentage is typically set conservatively and is then held or adjusted upwards later in the year based on a reassessment of precipitation and snow pack. Litigation filed by several"environmental interest groups (NRDC v. Kempthome (Case No. 05CV0I'207-OWW-GSA);,Pacific Coast Federation of Fishermen's Associations v. Gutierrez(Case No. 06CV002451-OWW)) has alleged that certain biological opinions and incidental take permits,granted byxstate and federal agencies for water permits in the Sacramento-San Joaquin Bay Delta inadequately analyzed impacts on species listed as endangered under the Federal Endangered Species Act (ESA). In 2007, Federal District Judge Wanger issued a decision, finding the United States Fish and Wildlife Service's biological opinion, for Delta smelt to be invalid. Judge Wanger issued an Interim Remedial Order and Findings of Fact and Conclusions of Law requiring that the SWP and Central Valley Project (CVP) operate according to certain specified criteria until a 42 Two types of deliveries are assumed for the SWP contractors: Table A and Article 21. Table A Amount is the contractual amount of allocated SWP supply, set by percentage amount annually by DWR; it is scheduled and uninterruptible. Article 21 water refers to the SWP contract provision defining this supply as water that may be made available by DWR when excess flows area available in the Delta(i.e., Delta outflow requirements have been met, SWP storage south of the Delta is full, and conveyance capacity is available beyond that being used for SWP operations and delivery of allocated and scheduled Table A supplies). Article 21 water is made available on an unscheduled and interruptible basis and is typically available only in average to wet years,generally only for a limited time in the later winter. 4-7 11 B -40")- Item 16. - 73 City of Huntington Beach Section 28YU Urban N/aterManagementF9an '_� - -_- ___ new biological opinion for the Delta smelt was issued by the United States Fish and Wildlife Service.

The latest 2009 State Water Project Delivery Reliability Report (2009 Report)is the most current of these reports dated August 2010. The 2009 Report shows a continuing erosion of the ability of the SWP to deliver water. For current conditions, the dominant factor for these reductions is the restrictive operational requirements contained in the federal biological opinions. For future conditions,it is these requirements and the forecasted effects of climate change. Deliveries estimated for the 2009 Report are reduced by the operational restrictions of the biological opinions issued by the U.S. Fish and Wildlife;'Serviee in December 2008 and the National Marine Fisheries Service in June 2009 governing the SWP and CVP operations. To illustrate the effect of these operational restrictions, the median value estimated for the primary component of SWP Table A deliveries for Current,Conditions in the 2005 Report is 3,170 thousand acre feet (TAF); in the 2007 Report is,2,980 TAF; and in the 2009 Report is 2,680 TAF; for a reduction of.almost 500 TAF. For the 2009 studies, the changes in run-off patterns and amounts are:included along with a potential rise in sea level. Sea level rise has the potential to require more water to be released to repel salinity from entering the Delta in,order to meet water quality objectives established for the Delta. The effect of the operational restrictions in addition to the incorporation of potential climate change impacts amounts to an estimated reduction of 970 TAF when the median value for annual:SWP deliveries for Future Conditions in the 2005 Report (3,750 TAF) is compared to,the updated value in the 2009 Report (2,600 TAF). DWR has altered operations of°the SWP to accommodate species of fish listed under the Federal and California Endangered Species Acts (ESAs). These changes in project operations have influenced.the manner:in"Which water,is diverted from the Bay-Delta and SWP deliveries to,"the southern part,of the State. Restrictions on Bay-Delta pumping beginning in 2008'under the Interim Remedial Order in NRDC v. Kempthorne have resulted in reduced„deliveries of SWP water to Metropolitan. Based on DWR estimates of SWP deliveries under the Interim Remedial Order, and assuming an equal division'of curtailments between the SWP and CVP,' Metropolitan has met _firm demands in calendar _years 2008, 2009 and 2010. However, Metropolitan has been withdrawing:supplies from surface and groundwater storage to meet current demands. Anticipating that storage could be significantly reduced by the end of 2010, Metropolitan and its member agencies are calling for voluntary water conservation to lower demands and reduce drawdown from water storage. In fact on April 14, 2009, Metropolitan adopted a Level 2 Allocation, which equates to a 10 percent reduction in 44 Assuming an equal division of curtailments between the SWP and the CVP is conservative and may have the effect of overstating'the amount of SWP curtailment. As an example, in January 2009, the U.S. Bureau of Reclamation, which operates the CVP, provided notice to agricultural customers that it intended to not provide any water deliveries to agricultural customers in 2009. Thus,in the short term it appears as though agricultural users which receive water through the CVP may suffer deeper water cuts as compared to water purveyors which receive water from the SWP. 11B -405- Item 16. - 75 City of Huntington Beach Section 4 2010 Urban Water Maf7agernent Plan regional water supplies. Based on similar water supply conditions, this same level of allocation was adopted on April 13, 2010 for this current fiscal year by Metropolitan. If necessary, mandatory water allocations could be imposed in the future to cause further reductions in water use and reduce drawdown from water storage reserves. Metropolitan's member agencies and retail water suppliers in Metropolitan's service area also have the ability to implement water conservation and allocation programs, and many of the retail suppliers in Metropolitan's service area have initiated conservation measures. To create a systemic solution to the issues facing the Delta (which have existed since the 1970's), Governor Schwarzenegger created the Delta Vision process, which is aimed at identifying long-term solutions to the conflicts in, the Bay-Delta, including natural resource, infrastructure, land use and governance issues. The Delta Vision Blue Ribbon Task Force presented findings and recommendations fora sustainable Delta as a healthy ecosystem and water supply source on January 17,,2008.' In addition,,state and federal resource agencies and various environmental and water user entities are currently engaged in the development of the Bay-Delta Conservation Plan, which, is aimed at addressing ecosystem needs and securing long-term operating permits for the SWP. The Bay-Delta Conservation Plan process is scheduled for completion during the third quarter of 2009, with acquisition of appropriate permits and,,completion of the associated environmental impact statement/impq'ct report. Recently, statewide officials have expressed support for the construction` of the peripheral canal, which would alleviate some of the delta species considerations by transferringriver water south before it reaches the Bay Delta. The issues, such as the'recent,dbcllne of some fish species in the Delta and surrounding regions and certain operational actions in the, Delta, may impact Metropolitan's water supply from the Delta. SWP operational requirements may be further modified through the consultation process for new'bio' logical opinions for listed species under the Federal ESA or from"the California Department of Fish and Game's actions regarding the California ESA. Decisions in current;or future litigation, listings of additional species (such as the longfin smelt), or new"regulatory requirements could adversely affect SWP operations"in the future by requiring additional export reductions, releases of additional water from storage, or other operational changes impacting water supply operations. Water Transfer"and Exchange Programs California's agricultural activities consume approximately 34 million acre-feet of water annually, which is 80 percent of the total water used for agricultural and urban uses and 40 percent of the water used for all consumptive uses. Voluntary water transfers and exchanges can make a portion of this agricultural water supply available to support the State's urban areas. Such existing and potential water transfers and exchanges are an important element for improving the water supply reliability within Metropolitan's service area and accomplishing the reliability goal set by Metropolitan's Board of Directors. Metropolitan is currently pursuing voluntary water transfer and exchange programs with state, federal, public and private water districts and individuals.

The specific amount of water Metropolitan can store in and subsequently expect to receive from the programs depends upon hydrologic conditions, any regulatory requirements restricting Metropolitan's ability to export water for storage, and the demands placed on the Semitropic Program by other 'program participants. During the recent dry year of 2008, the storage program delivered 125 TAF to Metropolitan. During wet years, Metropolitan has" the discretion to use the program to store, portions of its SWP entitlement water that are in, excess of the amounts needed to meet Metropolitan's service area demand. In Semitropic, the water is delivered to district farmers who use the water in'-lieu of pumping groundwater. During dry years, the districts return Metropolitan7s previously stored water to.Metropolitan by direct groundwater pump-in return and the exchange of State Water Project entitlement water. ' Arvin-Edison Storage Program: Metropolitan amended the groundwater storage program with Arvin-Edison Water Storage District in 2008 to include the South Canal Improvement Project. The project increases the reliability of Arvin-Edison returning higher water quality to the California Aqueduct. The program storage capacity is 350 TAF. . The specific amount of water Metropolitan', can expect to store in and subsequently receive from the programs depends upon hydrologic conditions and any regulatory requirements restricting Metropolitan's ability to export water for storage:" The storage program is estimated to deliver 75 TAF. During wet years, Metropolitan,has the discretion to use the program to store portions of its,SWP Table A supplies which are in excess of the amounts Deeded to meet Metropolitan's service area demand. The water can be either directly recharged into the groundwater basin or delivered to district farmers who use the water in-lieu of pumping groundwater. During dry years, the district returns Metropolitan's previously stored water to Metropolitan by direct groundwater pumping in return or by exchange of surface water supplies. • San Bernardino. !'alley MWD Storage Program: The San Bernardino"Valley- MWD Storage program allows for the purchase of a portion of San Bernardino Valley Municipal Water District's State Water Project supply. The program includes a minimum purchase provision of 20 TAF and the option of purchasing additional supplies when available. This program can deliver between 20 TAF and 70 TAF in dry years, depending on hydrologic conditions. The expected delivery for a single dry year similar to 1977 is 70 TAF. The agreement with San Bernardino Valley MWD also allows Metropolitan to store up. to 50 TAF of transfer water for use in dry years. Kern-Delta Water District Storage Program: This groundwater storage program has 250 TAF of storage capacity. When fully developed, it will be capable of 4-11 1113 -407- Item 16. - 77 City of Huntington BeaGh Section 4 2010 Urban Water Management Plan providing 50 TAF of dry-year supply. The water can be either directly recharged into the groundwater basin or delivered to district farmers who use the water in- lieu of pumping groundwater. During dry years, the district returns Metropolitan's previously stored water to Metropolitan by direct groundwater pumping in return or by exchange of surface water supplies. • Mojave Storage Program: Currently operated as a demonstration program, the program will store SWP supply delivered in wet years for subsequent withdrawal during dry years. When fully developed, the program is expected to have a dry- year yield of 35 TAF depending on hydrologic conditions., Central Valley Transfer Programs: Metropolitan expects to secure Central Valley water transfer supplies via spot markets and option contracts to meet its service area demands when necessary. Hydrologic and market conditions, and regulatory measures governing Delta pumping plant operations will determine the amount of water transfer activity occurring in any year. Transfer market"activity in 2003, 2005, 2008, and 2009 provide examples,of how Metropolitan has secured water transfer supplies as a resource to fill anticipated supply shortfalls needed to meet Metropolitan's service area demands. • In 2003, Metropolitan secured options to purchase approximately 145 TAF of water from willing sellers, in the Sacramento 'Valley during the irrigation season. These options protected against potential shortages of up to 650 TAF within Metropolitan's service'area that might have arisen from a decrease in Colorado River supply or as a result of-dnier than expected hydrologic conditions.., Using these options, Metropolitan purchased approximately 125 TAF of water for delivery to the California Aqueduct. • In 2005, Metropolitan, . in partnership with seven other State Water Contractors, secured options to,purchase approximately 130 TAF of water from willing sellers in the Sacramento Valley, of which Metropolitan's share was 113 TAF. Metropolitan also had the right to assume the options of the other State Water Contractors if they chose not to purchase the transfer water. Due to improved hydrologic conditions, Metropolitan and the other State Water Contractors did not exercise these options. • hi 2608, Metropolitan in partnership with seven other State ' Water Contractors, secured approximately 40 TAF of water from willing sellers in the Sacramento Valley, of which Metropolitan's share was approximately 27 TAF. • In 2009, Metropolitan in partnership with eight other buyers and 21 sellers participated in a statewide Drought Water Bank, which secured approximately 74 TAF, of which Metropolitan's share was approximately 37 TAF. Metropolitan's recent water transfer activities have demonstrated its ability to develop and negotiate water transfer agreements either working directly with the agricultural districts who are selling the water or through a statewide Drought Water Bank. Because of the complexity of cross-Delta transfers and the need to Item 16. - 78 11 B -408- City of Huntington Beach 2010 Cuban rater Management Plan Section 4 optimize the use of both CVP and SWP facilities, DWR and USBR are critical players in the water transfer process, especially when shortage conditions increase the general level of demand for transfers and amplify ecosystem and water quality issues associated with through-Delta conveyance of water. Therefore, Metropolitan views state and federal cooperation to facilitate voluntary, market- based exchanges and sales of water as a critical component of its overall water transfer strategy. In addition to the previously mentioned programs, Metropolitan also manages or participates in the following existing SWP programs located outside of its service area: • Sacramento Valley Water Management Agreement- (Phase 8 Settlement): Metropolitan is a signatory to the Sacramento Valley Water Management Agreement (Phase 8 Settlement) that includes work.plans to develop and manage water resources to meet Sacramento Valley in-basin needs, environmental needs under the SWRCB's Water Quality Control Plan, and export supply needs for both water demands and water quality. The agreement specifies about 60 water supply and system improvement projects by 16 different entities in the Sacramento Valley. • Monterey Amendment: Metropolitan was a signatory to the 1994 Monterey Amendment to resolve disputes between the urban ''and agricultural SWP contractors over how contract supplies are to be allocated in times of shortage by amending certain provisions of the long-term water supply contracts with DWR. The Monterey Amendment altered the water allocation procedures such that both shortages and surpluses would be shared in the same manner for all contractors, eliminating the prior "agriculture first" shortage provision. In turn, the agricultural contractors agreed, to permanently transfer 130,000 AF to urban contract6rssand permanently retire 45,000 AF of their contracted supply. • SWP Terminal Storage: Metropolitan has contractual rights to 65,000 AF of flexible storage at'Lake Perris(East Branch terminal reservoir) and 153,940 AF of flexible storage at Castaic Lake (West Branch terminal reservoir). This storage provides Metropolitan with additional options for managing SWP deliveries to maximize yield from the project. • Yuba Dry-year Water Purchase Program: In December 2007, Metropolitan entered into an agreement with DWR providing for Metropolitan's participation in the Yuba Dry Year Water Purchase Program between Yuba County Water Agency and DWR through 2025. • Desert Water Agency/Coachella Valley Water District (DWCV) SWP Table A Transfer: Under the transfer agreement, Metropolitan transferred 100,000 AF of its SWP Table A amount to DWCV effective January 1, 2005. DWCV pays all SWP charges for this water, including capital costs associated with capacity in the SWP to transport this water to Perris Reservoir as well as the associated variable costs. The amount of water actually delivered in any given year depends on that year's SWP allocation. Water is delivered through the existing exchange 111.3 -409- Item 16. - 79 City of Huntington Beach Section 4 2010 Urban Water h4anagement Plan ------------- - agreements between Metropolitan and DWCV. While Metropolitan transferred 100,000 AF of its Table A amount, it retained other rights, including interruptible water service, its full carryover amounts in San Luis Reservoir, its full use of flexible storage in Castaic and Perris Reservoirs, and any rate-management credits associated with the 100,000 AF. In addition, Metropolitan is able to recall the SWP transfer water in years in which Metropolitan determines it needs the water to meet its water management goals. The main benefit of the agreement is to reduce Metropolitan's SWP fixed costs in wetter years when there are more than sufficient supplies to meet Metropolitan's water management goals, while at the same time preserving its dry-year SWP supply. • DWCV Advance Delivery Program: Under this program, Metropolitan delivers Colorado River water to DWCV in advance of the exchange for their SWP Contract Table A allocations. By delivering enough water in advance to cover Metropolitan's exchange obligations, Metropolitan is able to receive DWCV's available SWP supplies in years in which Metropolitan's supplies are insufficient without having to deliver an equivalent,amount of Colorado River water. • DWCV Other SWP Deliveries: Since 2008, Metropolitan has provided DWCV's written consent to take delivery from the SWP facilities non-SWP supplies separately acquired by each agency. These deliveries include water acquired from the Yuba Dry Year Water Purchase`Program and the 2009 Drought Water Bank. Supply Management Strategies On the regional level, Metropolitan has taken a number of actions to secure a reliable water source for'its member agencies. Metropolitan recently adopted a water supply allocation plan for dealing with potential shortages that takes into consideration the impact on retail customers and the°economy, changes and losses in local supplies, the investment in and development of local resources, and conservation achievements.as Additional actions taken by Metropolitan during the first half of 2008 include the adoption of a $1.9 billion spending plan, increased rates and charges,46 and the funding of a new reservoir to benefit Colorado River supply capabilities.47 Metropolitan's approved budget for 2010/11 included rate increases-of 7.5 percent with another 7.5 percent increase planned for 2011/12 to maintain this spending for the improvement of water conveyance Eacilities, water transfers, and providing financial assistance to member agency's local conservation, recycling, and groundwater clean-up efforts 48 45 Metropolitan Water District Press Release dated February 12,2008. 46 Metropolitan Water District Board Meeting,March 11,2008,and Press Release of same date,regarding spending plan and adoption of rates and charges. 47 Metropolitan Water District Board Meeting,April 8,2008,and Press Release of same date,regarding new reservoir. 48 Metropolitan Water District, Annual Budget,which can be accessed at this link: h 4-114 Item 16. - 80 1113 -410- City of Huntington Beach 2010 Urban Water Management Plan Section 4 ... ........___- Metropolitan also supports a number of resource management actions and measures, which promote consistency in the available water supply during dry years. These actions and measures, segregated below by category, include: Conservation * Providing incentives to facilitate the installation of water conserving devices. Metropolitan is also looking at refining their current incentive program to include more options, streamlined administrative processes, and more standardization across programs to increase participation. Total incentive payments for FY 2006/07 were $15.4 million and for FY 2007/08 were $18.1 million, which created 8,300 AF and 7,400 AF of new conserved water savings, respectively, bringing the total to 120,000 AF of conserved annual water-savings,.since 1991. * Promoting water savings through legislative,measures. © Pursuing specific implementation strategies outlined in' Metropolitan's Conservation Strategy Plan,jointly developed with its member agencies. Local Resources(LRP) • Providing incentives of up to $250 per acre-foot to"expand water-recycling and groundwater recovery programs. Eighty-six participating water recycling and groundwater recovery projects are expected to collectively produce about 363,000 AFY once fully implemented. Since inception of the LRP in 1982, Metropolitan has provided more"Ahan $244 million for the production of about 1.3 MAF of recycled water and recovered groundwater. • Encouraging development of seawater' desalination by promoting improved regional facilitation and ,funding. Additional information on desalination is included latefin this section. • Updating policies, to allow for an open process to accept and view project applications on a continuous basis, with a goal of development of an additional 174,000 acre-feet per,year of local water resources. In-Basin Groundwater Storage • Promoting dry-year conjunctive use programs with member and-tetaill agencies, which provide more than 415,000 AF of additional storage within Metropolitan's service area with a contractual yield of more than 115,000 AF during dry conditions. Metropolitan has allocated $52.4 million to these programs to date. Metropolitan also has about 63,000 AF in local supplemental storage through agreements with-several member agencies. In-Basin Surface Water Storage - • Providing storage in Metropolitan's Diamond Valley, Lake Mathews and Lake Skinner Reservoirs. 4-15 Item 16. - 81 City of Huntington Beach Section 4 2010 Urban Water Vanagement Plan ............. ------- 0 Providing flexible storage in DWR's Castaic Lake and Lake Perris Reservoirs. Municipal Water District of Orange County(MWDOC) MWDOC represents its members at a regional, state and federal level, and advocates for the development and protection of imported water supplies and planning along with coordinating the water needs for its service area. MWDOC's water management goals and objectives include working together with Orange County water agencies, including the City, to focus on solutions and priorities for improving Orange County's future water supply reliability. MWDOC's engineering and planning staffs also represent'its member agencies' interests in such water planning efforts as Metropolitan's IR-P and Watei,Surplus and Drought Management (WSDM) Plan, the focus on Orange Co'urity"s water'future effort, and the Orange County Water Plan. Through these efforts,-the goal is to improve,water planning in Orange County to ensure a high degree of reliability and quality in future water supplies. Efforts of MWDOC to maintain a reliable water supply include a commitment to the intensive and cost-effective development of Orange',= County's Water resources. Development of local water supplie's will lessen Orange County's dependence on imported water. Therefore, in order to maintain a more reliable water supply, a number of projects including storage, recycling, conjunctive use with groundwater basins, ocean desalination and new groundwater development will contribute to enhanced water reliability. Programs and projects directly managed by MWDOC include exchanges and transfers, 01 participation with the "Best Management Practices (BMPs) as well as extensive conservation and education'al'.'program's available to its member agencies. These programs and projects support further water reliability for its member agencies and throughout Orange County.49 Orange County Water District (OCWD) As previously n6ted, OCWD was ronmed by a special act of the California legislature in 1933 to manage, replenish, regulate, and protect the groundwater supplies underlying central Orange County. To accomplish these goals, the District's enabling act empowers it to (1) provide for the conjunctive use of groundwater and surface water; (2) store water in underground basins or reservoirs; (3) regulate and control the storage of water and the use of storage space in the groundwater basin; (4) purchase and import water into the District; (5) transport, reclaim, purify, treat, inject, extract, or otherwise manage and control water for the beneficial use of persons or property within the district; and (6) improve and protect the quality of groundwater supplies within the Distri Ct.50 49 MWDOC. Regional Urban Water Management Plan.2010. 50 OCWD Groundwater Management Plan Update,July 2009 4-16 Item 16. - 82 1113 -41 2_ City of Huntington Beach 2010 Urban Water Management Plan Section 4 .......... ................ ................... The Orange County groundwater basin meets approximately 60 to 70 percent of the water supply demand within the District's boundaries shown in Figure 2.1-3. Nineteen major producers, including cities, water districts, and private water companies, pump water from the basin and retail it to the public. Since its founding, the District has grown in size by about 40 percent to its current 229,000 acres. Concurrent with this geographic growth, there has also, been a rapid growth in population. OCWD has met these challenges through innovative and creative solutions, which have yielded increased available groundwater supplies while protecting the long-term sustainability of the basin. Groundwater pumping from the basin has grown from approximately 150,000 acre-feet per year (AFY) in the mid-1950s to over 300,000 in recent years. One of the District's primary efforts has been the control of seawater intrusion into the groundwater basin, especially in two areas: the Alamitos Gap and the Talbert Gap. OCWD began addressing the Alamitos Gap intrusion by entering a partnership in 1965 with the Los Angeles County Flood Control District to operate injection wells in the Alamitos Gap. Operation of the injection wells forms a hydraulic barrier to seawater intrusion. To address seawater intrusion in the Talbert Gap, OCWD constructed Water Factory 21, a plant that treated secondary-treated water from the Orange County Sanitation District (OCSD) to produce purified water for injection. Water Factory 21, operated for approximately 30 years until it was taken off-line in 2004. It was replaced by an advanced water treatment system, the Groundwater Replenishment System (GWRS). The GWRS, the largest water purification project of its kind, began operating in 2008 to provide water for the Talbert Injection Barrier as well as to supply water to recharge/percolation basins in the-City of Anaheim. OCWD Long Term Facilities Plan OCWD's 'June 2009 Long Term Facilities Plan (LTFP) evaluated potential projects for implementation over a 20-year planning horizon. The LTFP's goal is to enhance basin and water quality management activities through achievement of the following three management objectives: (1) Cost effectively protect and increase the basin's sustainable yield; (2) Protect and- enhance groundwater quality; and (3) Increase operational efficiency. The LTFP identifies 19 priority projects grouped into the six categories as noted below:51 • Water Supply Facilities 1. GWRS Initial Expansion 2.

OCSD manages wastewater collection and treatment for approximately 479 square miles in central and northwest Orange County, which includes 21 cities, 3 special districts, and 2.5 million residents.52 OCSD utilizes the following two facilities: Reclamation Plant No. I in Fountain Valley and Treatment Plant No. 2 in Huntington Beach to treat a combined daily average of 230 million gallons of wastewater. Effluent from Reclamation Plant No. I is either routed to the ocean disposal system or is sent to OCWD for advanced treatment and recycling. 52 OCSD website,httP.

GWRS takes highly treated wastewater that would have previously been discharged into the Pacific Ocean and purifies it using a three-step advanced treatment process consisting of microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide. The process produces high- quality water that exceeds all state and federal drinking water standards.53 As noted on OCWD's website, the GWRS plant has been operational since January 2008. This state-of-the-art water purification project can produce up to 72,000 AFY of high- quality water, which can meet the needs of nearly 600,000 residents in north and central Orange County. Plant expansion to 101,000 AF, enough to serve an additional 250,000 residents, is currently under design. Regional Water Quality Control Board— Region'8 Background The State Water Resources Control Board (SWRCB) and the nine Regional Water Quality Control Boards (Regional Boards) are responsible,Ifor the protection and, where possible, the enhancement of the quality of California's waters. The SWRCB sets statewide policy, and together with Regional Boards, implements state and federal laws and regulations. Each of the nine Regional Boards adopts a Water Quality Control Plan or Basin Plan, which recognizes and reflects regional "differences in existing water quality, the beneficial uses of,the region's ground and surface waters, and local water quality conditions and problems' 4 In 1975, the Santa Ana Regional Water Quality Control Board (RWQCB) adopted the original Water".Quality Control,Plan (Basin Plan) for the Santa Ana River Basin. That plan was,updated in,1995, to address issues that had evolved over time due to increasing populations and changing water demands in the region. The scope of the document covers tSe Santa Ana River Basin, which includes the upper and lower Santa Ana River watersheds including northwestern Orange County. The Basin Plan was updated again in 2008 to include all amendments adopted since the 1995 update. The 2008 update also included related formatting change,but did not include any other substantive changes.51 In 2006, a triennial review of the Basin Plan was performed. In December 2006, at a public hearing, the RWQCB adopted Resolution No. R8-2006-0085, approving the Triennial Review Priority List and Work Plan. The Final 2006 Basin Plan Triennial Review Priority List consists of 36 Basin Plan issues, and reflects consideration of 53 Per OCWD's website, 54 Per the Santa Ana Region Basin Plan, litti):_uk,-ww.swreb.ca.�L,oi,;,rtiN,,qcl)8i!water issues/I pr grarns.."basin plan./does,chaptei-I.Pff 55 Per Santa Ana RWQCB website, hiti): :www.swreb.c i.f-)ovirwqc-b8.!'Water iSSLICS!programs:'basin plan/does/basin plan notes febrUar-y' 2 008 Update.pd 11 B -415- Item 16. - 85 City of Huntington Beach Section 4 2010 Urban Water Management Plan comments from stakeholders, USEPA, and staff. Staff conducted two stakeholder meetings, held on June 6, 2006 and September 13, 2006, to solicit public comments and recommendations for changes to the priority list. The list identifies issues, their proposed priority, and estimates of the resources necessary to address them.56 The Basin Plan is more than just a collection of water quality goals and policies, descriptions of conditions, and discussions of solutions. It is also the basis for the RWQCB's regulatory programs. The Basin Plan establishes water quality standards for all the ground and surface waters of the region. The RWQCB also regulates water discharges to minimize and control their effects on the quality of the region's ground and surface water. Permits are issued under a number of programs,and authorities. Water quality problems in the region are listed in the Basin Plan, along with the causes, where they are known. For water bodies with quality below the levels necessary to allow all the beneficial uses of the water to be met, plans for improving water quality are included. Legal basis and authority for the RWQCB reflects, incorporates, and implements applicable portions of a number of national and,statewide watergquality plans and policies, including the California Water Code (Porter-Cologne Water Quality Control Act) and the Clean Water Act. Key Regional Issues Water quality degradation due to high"concentrations of nitrogen and total dissolved solids (TDS) is the most ,significant regional water quality problem in the Santa Ana River Watershed (Watershed)'. _Historically,- the Santa Ana River likely flowed during most of the year, recharging deep alluvial groundwater basins in the inland valley and the coastal plain. However, irrigation projects eventually led to the diversion of all surface flow in the river, and the quantity of groundwater recharge diminished greatly. Water quality concerns_ in the Watershed focus on elevated concentrations of TDS and total inorganic nitrogen(TIN). " F On January 22, 2004, the Santa Ana Regional Water Quality Control Board adopted Resolution No. R8-2004-0001 to amend the Santa Ana River Basin Plan. The Amendment included revised boundaries for groundwater subbasins, now termed "groundwater management zones", revised total dissolved solids (TDS) and nitrate- nitrogen objectives for those zones, revised TDS and nitrogen wasteload allocations for- discharges of recycled water to the Santa Ana River and its tributaries, and revised reach designations for certain surface waterbodies.57 A Task Force was formed in 1995 to provide oversight, supervision, and approval of a study to evaluate the impact of TIN and TDS on water resources in the Watershed. The study is coordinated by the Santa Ana Watershed Project Authority (SAWPA), a joint 56 Further information on the triennial review can be found on the Santa Ana RWQCB website at: http ii��-��lvs�t rcb.ca.�ov:ttirochrih ater issues�roa rams:basin 7laavbasin plan review.shmal "Additional information on this Amendment can be obtained on the Santa Ana RWQCB website at: htt -St_vw.sis_rch,_�.,t31_rj_c,cl�hiti_tat_�r is4lie x,jprt ijiLi i s;b<asin pl_aii/Jocs%h;�a t�lsr5tz�ii` ldc _t 9it�al.t�dt Item 16. - 86 1113 -416- City of Huntington Beach 201 Urban Water Management Plan Section 4 .................................. .................................. ........... ............. powers agency of which OCWD and OCSD are member agencies, and Is investigating questions related to TINS and TDS management in the Watershed, including groundwater subbasin water quality objectives, subbasin boundaries, and regulatory approaches to wastewater reclamation and recharge.58 Water Resources and Water Quality Management Numerous water resource management studies and projects, focused on water quality and/or water supply, are in progress in the Region under the auspices of a variety of parties. Some of these activities bear directly on the implementation of the Basin Plan, while others may lead-to future Basin Plan amendments 'to incorporate appropriate changes, such as revised regulatory strategies for various dischargers. These investigations and the implementation of appropriate physical solutions are an essential and integral part of the effort to restore and maintain water quality'in the Region. 4.2 REGIONAL DEMAND AND SUPPLIES COMPARISON Metropolitan Water District Supplies and Demands As previously noted, the City of Huntington Beach obtains its imported water from MWDOC, its Metropolitan member agency. As a part of its Integrated Water Resources , , Plan Implementation Report process (IRP)59 I And more recently in its November 2010 Regional Urban Water Management Plan (RUWMP),,Metropolitan chose the year 1977 as the single driest year since 1922, and theyears 1990-1992 as the driest multiple (3) years over that same period. These years were selected because they represent the timing of the least amount-of available water resources from the SWP, a major source of Metropolitan's supply. Concurrently with the preparation of its 2010 RUWMP, Metropolitan also prepared a 2010 IRP Update, which was adopted by the Metropolitan Board of Directors on October 12, 2010. Based on Metropolitan's 2010 RUWMP and 2010 IRP, Tables 4.2-1 and 4.2-2 herein summarize Metropolitan's current imported supply availability and demand projections for average year;,,single, dry year, and multiple dry years .over the 20-year period beginiiing in 21015 and ending in 2035. The Supply projections include current programs and programs under development as well as in-region storage and programs. Reference is made to Metropolitan's 2010 RUWMP for a description of these programs under development, but they include only programs Metropolitan is confident can be implemented and do not include other more speculative regional programs. Even if all the programs under development are removed, there are surpluses in all years and 58 Santa Ana Regional Water Quality Control Board.Watershed Management Initiative.Revised May 2004. `9 Metropolitan develops Integrated Water Resources Plans (IRPs), which lay out how Metropolitan will secure and provide water to its customer base. These IRPs utilize hydrological and other data provided by DWR and are updated periodically through IRP Report Updates to reflect changing conditions. 421 1113 -417- Item 16. - 87 City of Hunlington Beach Section 4 2010 Urban Water Management Plata scenarios listed below. Demands are firm demands on Metropolitan and also include Metropolitan's commitments for IID-SDCWA transfers and canal lining. Table 4.2-1, summarizing single dry year demand data shows surpluses in all years ranging from a low of 148.3 percent (projected supply during a single dry year as a percent of single dry year demand) in 2015 to a high of 182.3 percent in 2020.

The area must depend on imported water supplies since natural precipitation is limited and the City cannot pump enough to fully meet its needs. Climatological data in California has been recorded since the year 1858. During the twentieth century, California has experienced three periods of severe drought: 1928-34, 1976-77 and 1987-91. The year 1977 is considered to be the driest year of record in the Four Rivers Basin by DWR. These rivers flow into the San Francisco Bay Delta and are the main source of water for the SWP. Southern California and, in particular, Orange, sustained few adverse impacts from the 1976-77 drought, but the 1987-91 and the 2008- 2010 droughts created considerably more concern for Southern California and Orange County. As a result, the City is vulnerable to water shortages due to its climatic environment and seasonally hot summer months. Response to a future drought should follow the water use efficiency mandates of the Metropolitan Water Surplus and Drought Management (WSDM) Plan, along with implementation of the appropriate stage of the City's Phased Water Conservation Plan. These programs are more specifically discussed in Section 8. 4.4 PLANNED WATER SUPPLY PROJECTS AND PROGRAMS TO MEET PROJECTED WATER USE 4.4.1 City of Huntington Beach Projects The City continually reviews practices that will provide its customers with adequate and reliable supplies. Trained staff continues to ensure the water quality is safe and the water supply will meet present and future needs in an environmentally and economically responsible manner. The City consistently coordinates its long-term water shortage planning with MWDOC and OCWD as described in other sections of this Plan. The City projects water demand will remain relatively constant over the next 25 years due to minimal growth combined with water conservation efforts. Any new projects will be irnpilemepted to better manage the Orange County Groundwater Basin resource and to replace or upgrade inefficient wells, rather than to support population growth and new development. Projects included in the City Capital five-year Capital Improvement program will improve the City's water supply reliability and enhance water operations. Those projects include the following: ® Distribution System Improvements — Various improvements to increase system redundancy and reliability. ® Water Main Replacements — Water main replacements at various locations throughout the City. These new pipelines will replace older deteriorated lines, thereby improving system reliability. 1113 -421- Item 16. - 91 City of Nur iflgtora .Beach ,Section 4 2010 Urban Water Management Plan • Well No. 8 — Well No. 8 has been out of service for several years because it produced sub-potable water. This well will be converted to an irrigation well, which will reduce domestic water demand from large turf areas and landscaping. • Well Nos. 3, 6, and 9 — A granular activated carbon filter will be installed at this well to reduce odor problems and increase long-term reliability of the well. • Well No. 10 Rehabilitation— This well was damaged by a local fire in September 2009. The well will be rehabilitated to improve system reliability. • Well No. 12 — On going studies regarding mitigation efforts to reduce chloride levels. • Peck Booster Station — This station will be converted to dual power/drive to increase reliability and flexibility of operations. • Edwards Hill Booster Station — This station has undergone major electrical rehabilitation to ensure station performance and reliability. • Water System Reliability Studies — Modeling work will be performed to suggest ways to increase system reliability, fire flow capacity and operational flexibility. • Water Master Plan — The City's Water Master Plan will be updated with an eye toward improving overall system reliability. , • Talbert Lake Diversion Project — To divert urban runoff to Central Park for natural treatment and water reuse. 4.4.2 Regional Agency Projects Since the City purchases imported water from the SWP and the Colorado River from Metropolitan,"via MWDOC,, the projects implemented by Metropolitan to secure their water supplies have a direct effect on Huntington Beach. In addition, OCWD's planned projects and groundwater and recycled water programs also benefit the City. Metropolitan Water District of Southern California (Metropolitan) Metropolitan_ is u7nplenienting water supply aitemative strategies for the region and on behalf of their member agencies to ensure available water in the future. Some of the strategies identified in Metropolitan's 2010 UWMP and referenced in previous sections of this Plan include: • Conservation • Water recycling and groundwater recovery • Storage and groundwater management programs within the Southern California region • Storage programs related to the SWP and the Colorado River Item 16. - 92 1113 .422- City of Huntington Beach 2010 Urban Water Management Plan Section 4 ............... ........ Other water supply management programs outside of the region These programs and strategies are discussed in further detail below. Conservation Target Metropolitan's conservation policies and practices are shaped by its Integrated Resource Plan and the California Urban Water Conservation Council (CUWCC) Memorandum of Understanding Regarding Water Conservation in California. Recycled Water, Groundwater Recovery, and Desalination Target Metropolitan supports the use of alternative water supplie's such as recycled water and degraded groundwater when there is a regional benefit to offset imported water supplies. Currently, about 335 TAF per year of recycled Water is permitted for use within Metropolitan's service area. Recycled uses include irrigation, commercial and industrial, seawater intrusion barriers, and groundwater,"recharge' applications. 'Metropolitan estimates that an additional 458 TAF per year of,new`recycled water usage can be developed by 2035 with a total potential recycled water usage of 1.0 MAF by 2050. Most of the current recycled usage is, for irrigation, groundwater replenishment and seawater barriers, with smaller amounts4sed in industrial applications. , Metropolitan recognizes the importance of member agencies developing local supplies and has implemented several programs to provide financial assistance. Metropolitan's incentive programs includ& • Competitive LRP:,Supports the development of cost-effective water recycling and groundwater recovery pr6.ie,cts that reduce demands for imported supplies. • Seawater Desalination Program (SDP): Supports the development of seawater desalination within Metr"Tolitan's service area. Additional information on the SDP program is included later in this section. Regional broundwater,Conjunctive Use Target Other programs within Metropolitan; which are aimed at maximizing water--supplies include storage and groundwater management pro-grams. The Integrated Resource Plan Update identified the need for dry-year storage within surface water reservoirs and the need for groundwater storage. In 2002, Diamond Valley Lake reached its full storage capacity of 800,000 AF. Approximately 400,000 AF of this total is dedicated for dry- year storage. Metropolitan has also developed a number of local programs to increase storage in the groundwater basins. The programs include: • North Las Posas: In 1995, Metropolitan and Calleguas Municipal Water District developed facilities for groundwater storage and extraction from the North Las Posas Basin. Metropolitan has the right to store up to 210,000 AF of water in this 4-27 1113 -423- Item 16. - 93 City of Huntington Beach Section 4 2010 Urban Water Management Plan ............ ............. basin. It is expected the North Las Posas program will yield 47,000 AF of groundwater from the basin each year. • Proposition 13 Projects: In 2000, DWR selected Metropolitan to receive financial funding to help fund the Southern California Water Supply Reliability Projects Program. The program coordinates eight conjunctive use projects with a total storage capacity of 195 TAF and a dry-year yield of 65 TAF per year. • Raymond Basin: In January 2000, Metropolitan entered into agreements with the City of Pasadena and Foothill Municipal Water District to implement a groundwater storage program anticipated to yield 22 TAF per year by 2010. • Other Programs: Metropolitan intends to expand the'conjunctive use programs to add another 80 TAF to groundwater storage. Other basins in the area are being evaluated for possible conjunctive use projects. State Water Project Target The-major actions Metropolitan is completing to improve SWP reliability include the following previously referenced programs: • Sacramento Valley Water Management Agreement(Phase 8 Settlement) • Monterey Amendment • SWP Terminal Storage • Yuba Dry-year,Water Purchase Program • DWCV SWP Table A Tra nsfer • DWCV Advance'Y' elivery'Pirogram • DWCV Othe'-SWP Deliveries Colorado River Aqueduct'(CRA) Target Metropolitan also receives' imported water from the CRA. Metropolitan, Imperial III) and Coachella Valley' Water District (CVWD) executed the Quantification Settlement Agreement (QSA) in October 2003. The QSA established the baseline water use for each agency and facilitated the transfer of agricultural water to urban uses. A number of programs have been identified to assist Metropolitan meet their target goal of 1.2 MAF per year from the CRA. The following information on these programs has been extracted from the Metropolitan's 2010 Regional UWMP: • Imperial Irrigation District/Metropolitan Water District Conservation Program: Under a 1988 agreement, Metropolitan has funded water efficiency improvements within IID's service area in return for the right to divert the water conserved by those investments. Under this program, III) implemented a number of structural and nonstructural measures, including the lining of existing earthen canals with concrete, constructing local reservoirs and spill interceptor canals, installing non- 4-28 Item 16. - 94 11 B -424- City of Huntington Beach 2010 Urban Water Manalgement Plan Section 4 ................. ___ ............. leak gates, and automating the distribution system. Other implemented programs include the delivery of water to farmers on a 12-hour rather than a 24-hour basis and improvements in on-farm water management through the installation of tailwater pumpback systems, and drip irrigation systems. Through this program, Metropolitan obtained an additional 105 TAF per year, on average upon completion of program implementation. Execution of the QSA and amendments to the 1988 and 1989 agreements resulted in changes in the availability of water under the program, extending the term to 2078 if the term of the QSA extends through 2077 and guaranteeing Metropolitan at least 85 TAF per year. The remainder of the conserved water is available to CVWD. — Palo Verde Land Management, Crop Rotation, and°Water Supply Program: In May 2004, Metropolitan's Board authorized a 35-year, land management, crop rotation, and water supply program with PVID. Under the program, participating farmers in PVID are paid to reduce their water'use by not irrigating a portion of their land. A maximum of 29 percent of the lands within the Palo Verde Valley can be fallowed in any given year. Under the terms of the QSA, Water savings within the PVID service area are made available to Metropolitan. This program p up to 133 TAF of water available t I provides 1 o Metropolitan in certain years, and a minimum of 33 TAF per year. As previously noted, in 2005, 2006, 2007, 2008, and 2009 approximately 108.7, ,105.0, 72.3, 94.3,,and., 102.2 TAF of water, respectively, were saved and made available to Metropolitan. In March 2009, Metropolitan and PVID entered into a one-y I ear supplemental fallowing program within PVID that provides for the fallowing of additional acreage, with savings j0 pr ected to be as much as 62 TAF. Of that total,24.1 TAF of water was saved in 2009,with the balance to be made available in 2010. • Southern Nevada Water Authority and Metropolitan Storage and Interstate Release Agreement: Southern Nevada Water Authority (SNWA) has undertaken extraordinary water conservation measures to maintain its consumptive use within Nevada's basic apportionment of 300 TAF. The success of the conservation program has resulted in unused basic apportionment for Nevada. As SNWA expressed interest in'storing a portion of the water with Metropolitan, the agencies along with the United States and the Colorado River Commission of Nevada entered into a storage and interstate release agreement in October 2004. Under the agreeme'rit, additional Colorado River water supplies are made available to ,Metropolitan when there is space available in the CRA to receive the water: Metropolitan has received 70 TAF through 2009. SNWA may call on Metropolitan to reduce its Colorado River water order to return this water no earlier than 2019,, unless Metropolitan agrees otherwise. • Lower Colorado Water Supply Project: In March 2007, Metropolitan, the City of Needles, and the USBR executed a Lower Colorado Water Supply Project contract. Under the contract, Metropolitan receives, on an annual basis, Lower Colorado Water Supply Project water unused by Needles and other entities with no rights or insufficient rights to use of Colorado River water in California, the beneficiaries of the project. A portion of the payments made by Metropolitan to 4-29 11B -425- Item 16. - 95 City of Huntington Beach Section 4 2010 Urban Water Managen�ent Plan .................. ................. Needles are placed in a trust fund for potentially acquiring a new water supply for Needles and other users of the Project should the groundwater pumped from the project's wells become too saline for use. In 2009, Metropolitan received 2.3 TAF from this project. Lake Mead Storage Program: In May 2006, Metropolitan and the USBR executed an agreement for a demonstration program that allowed the agency to leave conserved water in Lake Mead that would otherwise have been used in 2006 and 2007. USBR would normally make unused water available to other Colorado River water users, so the program included a provision, that water left in Lake Mead must be conserved through extraordinary conservation measures and not simply be water that was not needed by Metropolitan'in the year it was stored. This extraordinary conservation was accomplished through savings realized under the Palo Verde Land Management, Crop Rotation, and Water Supply Program. Through the two-year demonstration program, Metropolitan created 44.8 TAF of "Intentionally Created Surplus" (ICS) water. In'December 2007, Metropolitan entered into agreements to set forth the rules under which ICS water,is,developed, and stored in and delivered from Lake Mead. Tbe&aniount of water stored in Lake Mead, created through extraordinary conservation, that is available for delivery in a subsequent year is reduced by a one-time deduction of five percent, resulting in additional system water in storage in the lake, and an annual evaporation loss, beginning in the year following the year"the water is stored. Metropolitan created 55.8 TAF of ICS water through the Verde Land Management, Crop Rotation, and Water,Supply Program in 2009. As of January 1, 2010.,Metropolitan had a total of 79.8 TAF of Extraordinary Conservation ICS water in Lake Mead. The December 2007 federal guidelines concerning the operation of the Colorado River system reservoirs provided the ability for agencies to create "System Efficiency ICS" through the development and funding of system efficiency projects that save water that would otherwise be lost from the Colorado River., 'To that end, in 2008 the Central Arizona Water Conservation District (CAWCD), SNWA, and Metropolitan contributed funds for the construction of the Drop 2 Reservoir by the USBR. The purpose of the Drop 2 Reservoir is to increase the capacity to regulate deliveries of Colorado River water at imperial Dam reducing the amount of excess flow downstream of 6e dam by approximately 70 TAF annually. In return for its $28.7 million contribution toward construction, 100 TAF of water that remains stored in Lake Mead was assigned to Metropolitan as System Efficiency ICS. As of January 1, 2010, Metropolitan had 66 TAF of System Efficiency ICS water in Lake Mead. In 2009, Metropolitan entered into an agreement with the United States, SNWA, the Colorado River Commission of Nevada, and CAWCD to have USBR conduct a one-year pilot operation of the Yuma Desalting Plant at one-third capacity. The pilot operation began in May 2010 and is providing data for future decision making regarding long-term operation of the Plant and developing a near-term Item 16. - 96 1113 -426- City of Huntington Beach 2010 urban Water Management Plan Section 4 water supply. Metropolitan's contribution toward plant operating costs is expected to secure 23.2 TAF of System Efficiency ICS by 2011. • Hayfield Groundwater Storage Program: The Hayfield Groundwater Storage Program will allow CRA water to be stored in the Hayfield Groundwater Basin in east Riverside County (about 50 miles east of Palm Springs) for future withdrawal and delivery to the CRA. In June 2000, the Metropolitan Board approved the implementation of the Hayfield program and authorized storage of 800 TAF of CRA supplies when available. As of 2003, there were over 70 TAF in storage. At that time, construction of facilities for extracting the stored water began, but it was then deferred because drought conditions in the°.Colorado River watershed resulted in a lack of surplus supplies for storage. A prototype well was completed in August 2009. Hydrogeologic investigations indicate that conversion of the prototype well into a production well could extract as much as 5 TAF per year of previously stored water. When water supplies become more plentiful, Metropolitan may pursue this program and develop,storage capacity of about 400 TAF. CVP/SWP Storage and Transfers Target Metropolitan has focused on voluntary short and long-term transfer and storage programs with CVP and other SWP contractors. These previously referenced programs include: • Semitropic Storage Program • Arvin-Edison Storage Program • San Bernardino Valley Metropolitan Storage Program • Kern-Delta Water District Storage Program • Mojave Storage Program • Central Valley Transfer Programs Metropolitan'`s 2010 Regional UWMP indicates these programs can supply 402,000 AFY, 306,000'AFY and 274,000 AFY in average, single dry and multiple dry years, respectively in the year 2030.60 60 MWD's 2010 Regional UWMP,Section 7 4-31 11B -427- Item 16. - 97 City of Huntington Beach Section 4 20 10 Urban Water Managernent Plan Municipal Water District of Orange County(MWDOC) Projects Sufficient water storage, transfer and exchange, supply, and recycling programs will help to ensure adequate water supplies in the future and in time of drought. The need for local supplies and storage intensifies with Southern California's and the Orange County region's dependence on imported water to serve water demands. One of the most effective forms of storage in a highly dry and arid climate is conjunctive use wherein water is stored under ground during wet periods and pumped out during dry or drought periods. Although MWDOC is not responsible for carrying out specific supply development projects in the region, the MWDOC 2010 Regional Urban Water Management Plan discusses a number of water supply opportunities in Orange County. Additional details on each of these projects or programs can be found in Section 7 of MWDOC's RUWMP. Orange County Groundwater Conjunctive Use Program As discussed above, the Orange County Groundwater'Conjunctive Use Program was selected by Metropolitan in June 2003, funded by-Troposition 13, to construct groundwater conjunctive use projects ,that would store imported water in wet years for use in dry years. This is a 25-year project between'MWDOC, OCWD, and Metropolitan to store up to 60,000 AF of imported water in the Orange County groundwater basin for this purpose, extracting up to 20,000 AF of water during dry periods from 7-10 strategically sited wells. Although the City was not selected to participate in this program, the additional wells would reduce the region's dependence on imported water during dry periods and would provide greater reliability. Transfer and Exchange Opportunities • Mesa Consolidated Water District: Mesa plans to expand their Colored Water treatment Facility. With this expansion, Mesa is exploring opportunities that may develop into potential transfer or exchange opportunities. These would include the sale,of excess pumped water from the expansion to neighboring agencies. • IRWD Strand Ranch Water Banking Program: Irvine Ranch Water District (IRWD) -has completed negotiations with Metropolitan and MWDOC and prepared an agreement that will accommodate the recharge, storage and recovery of SWP water at the IRWD Strand Ranch Integrated Banking Project and delivery by exchange of this water to the IRWD service area. The project involved 50,000 AF of storage capacity located in Kern County. Water Supply Projects and Programs • Baker Water Treatment Plant: The Baker Pipeline Regional Water Treatment Plant is a 25 MGD proposed regional project that will be constructed at the —---- Item 16. - 98 11 B -428- City of Huntington Beach 2010 Urban Water Management Plan Section 4 existing IRWD Baker Filtration Plant site in the City of Lake Forest. The plant will treat untreated water from the Santiago Lateral and Irvine Lake delivered through the Baker Pipeline. The project will provide supply reliability to south Orange County by increasing local treatment capability from multiple water sources. The project is scheduled to begin construction in 2012 and come on line in 2013, providing 28,000 AFY or additional treated water to:south County agencies. • North Orange County Recycled Water Feasibility Study:, MWDOC, along with the City of La Habra, conducted a study to determine the feasibility of a recycled water system in North Orange County. The potential customers would include La Habra, Buena Park and Fullerton and the project 'would include a 2 MGD treatment plant located in the City of La Habra. Next steps will be a detailed investigation and pursuit of project funding as well as pursuing-additional users. • YLWD Recycled Water Study: Yorba Linda Water District (YLWD) is completing a Water Recycling Facilities Planning Study which will investigate,construction of a 5 MGD water recycling facility. r_ : . • IRWD Interconnection Project: This project became operational in 2009 and involved construction of a permanent interconnection .and pumping facilities between the IRWD potable water system and the Joint Regional Transmission Main and the Aufdenkamp Transmission Main that conveys water into South Orange County. .The project has the ability to transfer up to 30 cfs of supplies during emergency situations. • SMWD Upper Chiquita: reservoir Project: Santa Margarita Water District (SMWD) is constructing the Upper Chiquita Reservoir with a capacity of 244 MG, near Oso Parkwaya and the 241'Toll Road. The project will supply water to South Orange-County agencies during planned and unplanned service outages and emergencies. Construction is well underway and expected to be completed in summer 2011. • SCWD'Aliso Creek Streamflow Recovefy Facilities Project: South Coast Water District (SCWD).has conducted a preliminary investigation of a project of intercept arid` treat a portion of the urban _ninoff flows in Aliso-Creek to, supplement their potable water supply. The project would supply up to 2 MGD of product water to their potable water system or for blending with;recycled water supply. • San Juan Capistrano Recycled Water: The City of San Juan Capistrano is currently working with its neighboring agencies, SMWD and MNWD, to make arrangements to use recycled water, when available. • ETWD Recycled Water Distribution Capacity Expansion: El Toro Water District (ETWD) is currently in the planning stage of a significant expansion to its 4-33 11B - 29- Item 16. - 99 City of Huntington Beach Section 4 2016 Urban Water Management Plan recycled water distribution capacity. The proposed project would construct a new recycled water distribution system supplied by recycled water from Moulton Niguel Water District (MNWD) and IRWD. The proposed project is expected to be in service by 2015 and would increase ETWD's recycled water supply by as much as 750 AFY. Brackish Water Desalination • Mesa Colored Water Treatment Facility Expansion and Garden Grove Nitrate Blending Project: These two projects were described previously under in Section 3 under Orange County Groundwater Basin Groundwater Quality Protection Projects. • SCWD Capistrano Beach Groundwater Recovery Facility" -Expansion: SCWD plans to expand their current 1 MGD Groundwater Recovery Facility to reach the goal of 2,000 AFY. The expansion is anticipated to begin in 2012 and be completed by 2014. • San Juan Desalter Groundwater Recovery Plant Expansion: The current plant has been impacted by Methyl,Tert-Butyl Ether (MTBE), reducing production to about 2 MGD since 2008. The installation of a Granular Activated Carbon Filter is expected to allow the full 5.1 MGD`by winter of 2011 and is expected to increase capacity to 7 MGD in the future when additional wells are brought on line. Ocean Desalination , • Huntington Beach Seawater Desalination Project: Poseidon Resources LLC, a private company, is developing the Huntington Beach Seawater Desalination Project to be located adjacent to the AES Power Plant in the City of Huntington Beach along Pacific Coast,Highway and Newland Street. The proposed project would produce up to 50 MGD (56,000 AFY) of drinking water and will distribute water to coastal and south Orange County to provide approximately 8% of Orange County's water supply needs. The project supplies would be distributed to participating agencies through a combination of (1) direct deliveries through facilities including the East Orange County Feeder #2, the City of Huntington Beach's distribution system, and the West Orange Coonty water Board Feeder#2, and (2) water supply exchanges with agencies with no direct connection to facilities associated with the Project. • South Orange Coastal Ocean Desalination Project: MWDOC is proposing a desalination project in joint participation with the Laguna Beach County Water District, MNWD, City of San Clemente, City of San Juan Capistrano, SCWD, and Metropolitan. The proposed project is located adjacent to the San Juan Creek in Dana Point and will provide 15 MGD (16,000 AFY) of drinking water, which is up to 25%of the needs of the participating retailer agencies. Item 16. - 100 1113 -430- City of Huntington Beach 201 Urban Water Management Plan Section 4 • Camp Pendleton Seawater Desalination Project: San Diego County Water Authority is studying a desalination project to be located at the southwest comer of Camp Pendleton Marine Corps Base adjacent to the Santa Margarita River. The initial project would be a 50 or 100 MGD plant with expansions in 50 MGD increments up to a maximum of 150 MGD making this the largest proposed desalination plant in the United States. The project is currently in:the feasibility study. MWDOC and south Orange County agencies are maintaining a potential interest in the project, but at this time they are only pursuing limited fact finding and monitoring of the project. Orange County Water District(OCWD) Projects OCWD is dedicated to maintaining a reliable supply of water for,its groundwater users. As noted in Section 4.1 of this Plan, OCWD' LTFP,has proposed implementation of 19 projects over the next twenty years, all aimed at increasing the basin's sustainable yield, 0j 9 I " I protecting and enhancing groundwater quality and increasing operational efficiency. Additionally, as noted in Section 3.1 of this Plan, OCWD has also implemented or jointly sponsored several water quality improvement projects;" including the North Basin Groundwater Protection Project, South Basin Groundwater Protection Project, the Irvine Desalter, the Tustin Desalters, the Garden Grove Nitrate"Removal Project, the River View Golf Course Well Conversion, the�5-mgd Mesa Consolidated Water District Ozone Oxidation Treatment Plant, and the IRWD's Deep Aquifer Treatment System(DATS). In addition to the aforementioned projects, OCWD has also propo sed or began implementation on the folfowirig twelve projects, all of which are aimed at expanding recharge operations:61 I. Desilting Improvement Program —Removal of sediment from Santa Ana River water'will increase infiltration"rates. A feasibility study identified proposed treatment systems for pilot testing. 2. Mid-Basin Injection — This,project would inject high quality GWRS water into the-Principal aquifer in the central portions of the Basin, where most of the pumping occurs, thereby reducing low groundwater levels due to pumping. 3. Santiago Creek.Enhanced Recharge— Two improvements to Santiago Creek in the City of Orange are being considered-to enhance recharge;capacity. One project consists of cutting a water conveyance channel through a, concrete-lined creek channel to deliver a flow of water downstream of Hart Park. The second project will look at the feasibility of constructing three small new recharge basins adjacent to Santiago Creek. 4. Subsurface Recharge — This project would involve construct'ing subsurface horizontal infiltration recharge galleries beneath parks or school:athletic fields. These infiltration galleries would allow percolation of GWRS water, treated MWD water or filtered Santa Ana River recharge water into the basin. 6 1 As referenced in Section 4.5 of the July 2009 OCWD Groundwater Management Plan Update 4-35 11B 43)1- Item 16. - 101 City of Huntington Beach Section 4 2010 Urban Water Management Plan .......... ----------........... ...........................1---...........---- 5. Recharge Basin Rehabilitation — Periodic mechanical cleaning of the basins removed clogging sediments, thereby increasing recharging capabilities. 6. Burris and Lincoln Basins Reconfiguration —Proposed modifications to Burris and Lincoln Basins will improve recharge capability. 7. Five Coves and Lincoln Basins Bypass Pipeline — Piping modifications to the Upper Five Coves, Lower Five Coves, Lincoln, and Burris basins would allow water transfers between the four basins and would eliminate the need to take Burris Basin out of service while cleaning of the other four-basins. 8. Santiago Basins Pump Station — Reconstructing an inefficient pump station for the basins will increase recharge capacity and allow for more flexible and efficient operations. 9. Placentia and Raymond Basins Improvements.— Planned improvements to Placentia and Raymond Basins will increase-recharging cat`a'bilities in these basins. 10. Santiago Basins Intertie — Constructing 'a,,,connection between the Bond and Blue Diamond Basins would allow greater flexibility in managing recharge water. 11. Olive Basin Pump Station — Planned improvements to Olive Basin including installation of a pump station and drain pipe will 'allow the basin to be drained, cleaned and quickly restored to service.-, 12. Prado-Recharge Facilities Model This proposed mathematical model of Prado storage, Santa Ana River flow, and each recharge facility would simulate how the recharge system operates in conjunction with Prado storage and the river. The model would-allow evaluation of changes in recharge that would occur if the District were to construct improvements'io existing facilities, build new recharge facilities;or achieve'incre'aged 1levels of storage at Prado Dam. Orange County Sanitation Districts (OCSD) As mentioned earlier, OCSD supplies treated wastewater to OCWD for further treatment. OCWD relies on recycled water from OCSD's treatment facilities to protect the Basin through seawater intrusion,barriers and landscape irrigation. OCSD in conjunction with OCWD have implemented the GWR-) placed into operation in 2008. The GWRS project helps to maintain and improve the reliability of the region's water supply. Further discussion on water recycling is included in Section 9 of this Plan. 4.5 EXCHANGE OR TRANSFER OPPORTUNITIES The City has not entered into any agreements for the transfer or exchange of water other than through MWDOC. However, Metropolitan is exploring options that would benefit the region. These exchanges were discussed earlier under proposed projects for the region. 4-36 Item 16. - 102 1113 -432- City of Huntington Beach 2010 Urban Water Management Plan Section 4 ............... -.1--. - .... ............ 4.6 DESALINATED WATER OPPORTUNITIES Seawater desalination represents a significant opportunity to diversify the region's water resource mix with a new, locally controlled, reliable potable supply. Like conservation, recycling, urban water runoff, and other new local supplies, seawater desalination will increase regional supply reliability by offsetting existing and future demands for imported water. Regional Desalination Projects Supported by Metropolitan As noted in its 2010 Regional UWMP, Metropolitan continues to'pursue a target for seawater desalination of 150,000 AFY by 2025, and several local and retail water agencies have identified seawater desalination as an important component of their water supply portfolio in their Urban Water Management Plans. The implementation of large-scale seawater desalination plants in California offers many opportunities and challenges. In the past decade, advances in energy efficiency and membrane technology have reduced the cost of seawater d6salination relative to the costs for imported water supplies and other supply alternatives. Challenges to seawater desalination include high capital and operation costs, pre-treatment design, addressing environmental issues, system integration; and navigating an uncertain permitting process. Metropolitan's member agencies are actively,, pursuing research into alternative intake and outfall technologies, process designs, and treatment-`alternatives,: which could minimize some of the environmental issues and lower unit costs. Metropolitan has encouraged the development of seawater desalination projects since it created the Seawater Desalinatio'n Program (SDP) in 2001. Metropolitan currently has four ongoing SDP agreements in,place,with a fifth one on hold. These five SDP projects, as well as three'additional potential desalination projects within Metropolitan's service area, are summarized in Table 4.16. Of the projects listed in 'Table 4.6, the Carlsbad Seawater Desalination, project is the farthest along, having obtained all the necessary local, State and Federal pen-nits required to begin construction. However, some legal challenges to these permits surfaced in 2010. Metropolitan promotes- tht� development of local sewval&r desallinatiOn pirojects by providing regional facilitation, supporting member agency projects during permit hearings and other proceedings, coordinating responses to potential legislation and regulations, and working with the member agencies to resolve related issues such as greenhouse gas emission standards and seawater intake regulations, which could impact seawater desalination projects. Metropolitan has also formed a special Board Committee to seek additional ways to promote potential projects and explore opportunities for developing regional seawater desalination supplies. 4-37 11B -433- Item 16. - 103 City of Huntington Beach Section 4 20 10 Urban Water Management Plan ............. ........... ...........

Chapter 6(a) of Proposition,50 allocated the sum of$50 million for grants for brackish water and ocean water desalination pr"iccts. This grant program, administered by DWR, aimed to assist local public agencies in the development of new local water supplies through the construction of brackish water and ocean water desalination projects. The program also aimed to help advance water desalination technology and its use by means of feasibility studies, research and development, and pilot and demonstration projects. Two rounds of funding were conducted (2004 and 2006) under this grant program, which resulted in the investment of about $50 million to support 48 desalination projects. These projects included seven construction projects, 14 research and development projects, 15 pilot plants and demonstration projects, and 12 feasibility studies. 62 DWR's desalination website can be accessed at this link: .......... 4-38 Item 16. - 104 1 It3 -434- City or Huntington Beach 20 10 Urban Water Management Plan Section 4 ........... The California Legislature also approved Assembly Bill 2717, which asked DWR to convene the California Water Desalination Task Force to investigate potential opportunities and impediments for using seawater and brackish water desalination, and to examine what role, if any, the State should play in furthering the use of desalination technology. A primary finding of the Task Force was that economically and environmentally acceptable desalination should be considered as part of a balanced water portfolio to help meet California's existing and future water supply and environmental needs. The Task Force arrived at 41 key findings and made 29 major recommendations relating to seawater and brackish water desalination.63 63 A complete listing of the Task Force Report's findings and recommendations is available at this website: 3q 1113 -135- Item 16. - 105 City ofHuntington Beach Section 4 2010 Urban Water Management Plan This page intentionally left blank 4-40 Item 16. - 106 11 f3 -43 - City of Huntington Beach 2010 Urban Water Management Plan Section 5 ........................... ---------- ------------ 5 WATER SUPPLY BASELINES AND TARGETS AND WATER SUPPLY RELIABILITY COMAPARISON TABLES 5.1 WATER BASELINES AND TARGETS To comply with the SBx7-7 water conservation legislation, water suppliers must first establish a baseline water usage, which is then used to set targets for 2015 and 2020. The SBx7-7 legislation stipulates that targets must be established by using one of four allowable methods briefly defined as follows: • Method 1: Per capita daily use equals eighty percent of the water supplier's baseline per capita usage; • Method 2: Per capita daily use is set based on performance standards applied to indoor residential use; landscape area water use, and commercial,,,industrial and institutional use; • Method 3: Per capita daily use is set at-,95 percent of the applicable cable State hydrologic region target based on DWR's April 30, 2011 draft 10x2020 Water Conservation Plan (Huntington Beach is in the'So'uth Coast Region-4); and • Method 4: Per capita daily use,is set based on standards consistenti with CUWCC BMPs Detailed information on th'e,calculation of Huntington"-Beach's baseline water usage and 2015 and 2020 per capita water conservation targets can be found in Appendix E, a Technical Memorandum dated March 29, 201.1, entitled "20x2O2O Baseline Calculation & Water Use Target Method Selection. As noted in Appendix E, the City s per capita usage baseline average, minimum baseline average and S]B70' water conservation targets for 2015 and 2020 have been established as follows: el • Baseline Average (based on 10-year data from 1996-2005)= 159.1gpcd • Minimum Baseline Average (based on 5-year data from 2004-2008) = 144.6 gpcd • 2015 Water Conservation Target= 148.4 gpcd • 2020 Water Conservation Target= 137.4 gpcd 5.2 WATER SUPPLY RELIABILITY COMPARISON TABLES Tables 5.2-1 through 5.2-7 compare the City's anticipated available water supply with expected demands for normal, single dry and multiple dry years beginning in 2010 and extending through 2035. As shown on Table 5.2-1 for Normal Water Years, which includes growth projected per Appendix E, following the Total Demand row, the per capita consumption for 2020 is Q-1 1 i B -437- Item 16. - 107 City of Huntington ,Beach Section 5 2010 Urban Water Management Plan 137.5 gpcd, which is only slightly off the target; and the 2015 projection is 139.6 gpcd, which is below (in compliance with) the target. Demands were developed using land use projections and then divided by the population projections from the Draft 2010 OCP. These per capita figures in Table 5.2-1 are conservative as they do not include any credit for the City's share of indirect recycled water use for the GWRS, which was over 1,000 acre-feet in 2010. Even if the GWRS indirect recycled water credit does not increase and remains at around 1,000 AFY, the 2020 per capita figure for the City would be reduced from 137.5 to 133.4 gpcd, which is 4 gpcd below the target. The City will, however, continue to pursue water conservation efforts on their own and along with MWDOC.

The City of Huntington'Beach's fair share for affordable housing units under the 2008- 2014 Regional Housing Needs Assessment (RHNA) requirements is as shown in Table 5.3-1.66 Table 5.3-1 City of Huntington Beach Share of Regional Housing Needs 2008-2014 RHNA f"Ir 0_1 ' X gr Income Grow p' Number of tinits-, Very Low 454 22 % Low 369 17% Moderate 414 20 % High 855 41 % TOTAL 2,092 100.0% As shown in Table �5.3-1, the very low and low income dwelling units total to 823 (454+369) by 2014, which are the lower income housing units subject to the new Water Code requirements described in the first paragraph of this section. According to the City's 2010 Housing Element, Status Report approved at the City Council meeting of May 16, 2011, a total of 51 very'low and 35 low income units were completed toward the above goals by the end of the calendar year 2010. That leaves a remaining need for 737 very low and low income units (823-86). Using the highest per residential dwelling unit (DU) demand factor for new developments (169 gal/DU from Appendix E for the Downtown Area) times the 737 dwelling units, these low income units would generate a GeMland of 1214,553 gpd or 140 AFY by 2014. There is more than enough increase shown in the M&I (and specifically residential) water demand increases to accommodate this increase in low income housing shown in the City's projections between 2010 and 2015. 64 All California Law Codes can be accessed at this website: Section 10631.1 of the California Water Code is available at this website: ht w%v�N it) ot Lgim-q1, 0001-11000&06-iQ630-10614 k 65 Section 500.795 of the Health and Safety Code is available at this website: -5 1000&filel_5005O_IM06 66 City of Huntington Beach 2008-2014 Housing Element. 5_9 1113 -445- Item 16. - 115 City of Huntington Beach Section 5 2010 Urban Water Management Flan 5.4 WATER USE REDUCTION PLAN As demonstrated from the historical water usage data presented in Appendix E, the City has realized substantial reductions in per capita water usage in recent years. In fact, the City has met its 2015 water conservation target for each of the past six years (2005-2010) and has met its 2020 target for the past two years (2009 and 2010). Even ignoring the past two drought years (2009 and 2010) and assuming the three year non-drought period preceding that (2006-2008) was more representative (when baseline per capita usage was 140 gpcd), it appears that achieving the 2015 and 2020 water conservation per capita demands of 148.4 and 137.4 are well within reason. The demand projections shown in Table 5.2-1 and the text in Section 5.2 indicate that both the interim 2015 goal and the 2020 goal will be met. The City plans to meet or exceed its SBx7-7 water conservation targets, through a variety of means including: • Receiving additional indirect credits for recycled water use through the planned expansion of the joint OCWD/OCSD GWRS project; • Encouraging residents and businesses in the City to conserve water; • Educating the public through a-variety of programs on the need for continued water conservation; • Continuing to operate and maintain the water distribution system with an eye toward reducing water losses by repairing or eliminating any leaks that may develop as soon as practical; • Encouraging or requiring new developments to install water conservation fixtures and landscape with low water use plant materials (xeriscape); • Utilization of captured urban runoff and colored water from Well No. 8 for irrigation of parks and landscaping along Goldenwest Street. 10 Item 16. - 116 1113 -44 - City of Huntington Beach 2010 Urban Water Management Plan Section 6 ............_............... ........... .......... 6 WATER USE PROVISIONS 6.1 PAST, CURRENT AND PROJECTED WATER USE AMONG' SECTORS Since 1990, new connections have been added at a rate of approximately one percent per year, but that rate declined in recent years due to economic conditions.:, Due to new plumbing efficiency standards, landscape guidelines, and other water use efficiency programs, water demand is projected to increase at a declining rate of!less than one percent per year in future years.

However, this quantity of water is estimated and taken into consideration when calculating unaccounted-for water. 6-1 1 1B -447- Item 16. - 117 City of Huntington each Section 6 20 10 Urban Klbter Manager gent P/an ............. .......... • Water used by the Fire Department to fight fires. This water is also not metered. • Customer meter inaccuracies. Meters have an inherent accuracy for a specified flow range. However, flow above or below this range is usually registered at a lower rate. Meters become less accurate with time due to wear. Unaccounted-for water was 9.9 percent in 1995/96, but according to the City's 2005 Water Master Plan, averaged 6.4% during the nine year period from 1996/97 to 2004/05. During the five year period from 2005/06 through 2009/10, unaccounted-for water has averaged 5.3 percent. Thus, over the past 14 years, unaccounted-for water has averaged 6.0 percent. The decrease in unaccounted-for water sine 1995/96 can be partially attributed to a leak detection survey conducted for the City in 1996/97. A total of 498 miles of pipeline was surveyed, with a water loss of approximately 67,000 gpd quantified from 17 identified leaks. The annual water loss from these leaks was quantified as approximately 24.4 million gallons. The City repaired all of the leaks identified in the survey and the City has since implemented an on-going leak investigation and repair 6 Program as a measure to keep water losses to a minimum while facilitating cost savings. 6.2 WATER SERVICE CONNECTIONS BY SECTOR Table 6.2-1 shows the current and projected number of water service customers by sector from 2005 through 2035.

The City was officially voted in as a member of the CUWCC at the September 21, 2000 plenary session of CUWCC. MWDOC implements many of the urban water conservation BMPs on behalf of its member agencies, including the City of Huntington Beach. MWDOC's 2010 Regional Urban Water Management Plan should be referred to for a deia'iled discussion of each regional BMP program. 7.2 DETERMINATION OF DMM IMPLEMENTATION As Signatory to the MOU, the City has committed to a good faith effort in implementing the 14 cost-effective BMPs. "Implementation" means achieving and maintaining the staffing, funding, and in general, the priority levels necessary to achieve the level of activity called for in each BMP's definition, and to satisfy the commitment by the signatories to use good faith efforts to:optimize savings fiom implementing BMPs as described in the MOU. A BMP as defined'in the MOU is a"practice for which sufficient data are available from existing water conservation practices to indicate that significant conservation or conservation related benefits can be achieved; that the practice is technically and economically reasonable and not environmentally or socially unacceptable; and that the practice is not otherwise unreasonable for most water agencies to carry out." These 14 BMPs include technologies and methodologies that have been sufficiently documented in multiple demonstration,projects that result in more efficient water use and conservation. Many of the BMPs are implemented by the City in coordination with MWDOC and their regional conservation programs. Specifically, the 14 BMPs include: 1. Water survey programs for single-family residential and multifamily residential customers 2. Residential plumbing retrofit 3. System water audits, leak detection, and repair 4. Metering with commodity rates for all new connections and retrofit of existing connections 5. Large landscape conservation programs and incentives 6. High-efficiency washing machine rebate programs 7. Public information programs I 1B -449- Item 16. - 119 City of HLIOtingtOn Beach Section 7 2010 Urban Water Mat7agernent Plan 8.

Water waste prohibition 14. Residential ultra-low-flush toilet replacement programs As signatory to the MOU, the City is responsible for completing and submitting BMP Activity Reports to the CUWCC every two years for each year prior. The City's BMP Activity Report is a comprehensive document that shows implementation of each BMP and provides a determination of implementation from the City's 2000 UWMP. The City has maintained complete compliance with all the BMPs to date. As noted in Section 1.2 of this UWMP, AB 1465 (2010), clarifies that urban water suppliers that are members of the CUWCC and comply with the provisions of the "Memorandum of Understanding Regarding Urban Water Conservation in California" dated December 10, 2008, as it may be amended (MOU), may submit their annual reports required under the CUWCC MOU as evidence' of compliance without the need for any additional documentation in their UWMPs. With that in mind, the City of Huntington Beach's Activity Reports for reporting years 2006-2007 and 2008-2009 are included in Appendix F as evidence of BMP compliance. These reports indicate the City is on track for meeting BMP coverage in its-service area according to the MOU. 7-2 Item 16. - 120 11 B -4_5'O City of Huntington Beach 201 Urban Water Management Plan Section 8 -_............... 8 WATER SHORTAGE CONTINGENCY PLAN 8.1 INTRODUCTION California's extensive system of water supply infrastructure, its reservoirs, groundwater basins, and inter-regional conveyance facilities, mitigates the effect of short-term dry periods. Defining when a drought begins is a function of drought impacts to water users. Drought is a gradual phenomenon. Although droughts are sometimes characterized as emergencies, they differ from typical emergency events. Droughts occur slowly, over a multiyear period. Drought impacts increase with the length of a drought, as carry-over supplies in reservoirs are depleted and water levels in groundwater basins decline. To meet short-term water demand deficiencies, and, short' or long-term drought requirements, the City of Huntington Beach will implement its own Water shortage policy based upon Chapter 14.18 of the City's Municipal Water Code. In addition, the City's Water Efficient Landscape Requirements, included in Chapter 14.52' ofAhe City's Municipal Code, sets forth standards for landscape irrigation during drought and non- drought times, and acknowledges the constant need..to establish long-term water efficiency. Chapter 14.16 of the Municipal Code also establishes overall Water Use Regulations, including regulations for water meters. Provisions of the City's Municipal Code will be implemented in congruence with,the policy of Metropolitan, MWDOC and OCWD's water shortage/drought activities. '�MWDOC's policy will be based on Metropolitan's adopted Water Surplus and Drought Management Plan (WSDM Plan) as well as their Water Supply Allocation Plan as revised in'' June 2009. The WSDM Plan is designed to guide management of regional water supplies to achieve reliability goals for Southern California. The Water Supply Allocation Plan is designed to provide a framework for administering an allocation should a water shortage be declared. 8.2 STAGES OF ACTION City of'Huntington Beach Water Shortage Response In the event of a water shortage, the City's Director of Public Works and the City Administrator, or their designated representative, are authorized and directed by City Council to implement provisions of the Water Management Program. All actions taken will be confirmed at the earliest practicable time by the City Council. The Director of Public Works determines the extent of conservation or water use efficiency required through the implementation and/or termination of particular conservation stages for the City to prudently plan for and supply water to its customers. The City Council directs the City Administrator to order the appropriate stage of water conservation. However, in the case of local emergencies, the City Administrator has the authority to order the implementation of the appropriate stage of water conservation subject to ratification by the City Council within seven days thereafter. 11B -451- Item 16. - 121 City of Huntington Beach Section 8 20 10 Urban Water Management Plan As defined in Chapter 14.18 (included in Appendix G) of the City's Municipal Water Code, a water shortage is declared based on one or more of the following conditions: ® A general water supply shortage due to increased demand or limited supplies; • A major failure of the supply, storage and distribution facilities of the Metropolitan Water District of Southern California or of the City occurs; and/or ® A local or regional disaster, which limits the water supply. The City's Water Management Program includes three levels,or stages of water shortage actions, which take effect upon declaration. The Water Management Program, defined in Chapter 14.18 of the Huntington Beach Municipal Code, includes mandatory conservation phase implementation. The Director of Public Works,shall determine the extent of the conservation required through implementation and/or termination of particular conservation stages to allow the City to plan for and supply water to its customers, including consumption reduction up to 50%. As a MWDOC member agency, the City will follow the stages of action set forth by Metropolitan, as detailed below, which accomplish and ensure 100% reliability. The Water Management Program includes various permanent water conservation requirements including limits on watering hours and duration,e prohibition of excessive water runoff, prohibitions on hard surface 'Wash down, obligations to fix leaks, prohibition of non-re-circulating fountains and water features, prohibition of serving water in restaurants unless expressly requested, and other requirements. As specified above, the Program includes three levels of water shortage. In addition to the permanent conservation requirements, a Level I Water Supply Shortage includes limits on watering to three days a week (two per week from November through March) and a specific time allotment of 72 hours to repair leaks or breaks. A Level 2 Shortage decreases the watering days to two per week ('1, per week from November through March) and reduces the time allotted to fix leaks to 48 hours, plus limits on filling ornamental lakes or ponds, limits on vehicle washing, and limits on pool filling or re-filling. A Level 3 Shortage prohibits irrigation with potable water with certain exceptions, reduces the allotment of time to repair leaks to 24 hours, prohibits new water connections with certain exceptions, puts 'limits on issuance ofnexv building pen-nits, si-I-spends consideration of annexations to the water service area, and -allows the City to discontinue service to consumers who willfully violate these provisions. Rationing Stages and Reduction Goals To meet short-term water demand deficiencies and short- or long-term drought requirements, Huntington Beach will implement its own water shortage policy in accordance with the City's Water Management Program consistent with the policy of MWDOC, which is anticipated to be based on Metropolitan's WSDM Plan. The WSDM Plan defines the expected sequence of resource management actions Metropolitan will take during surpluses and shortages of water to minimize the probability of severe 8-2 Item 16. - 122 11 B -4 5'2- City of Huntington Beach 2010 Urban Water h4an agement Plan Section 8 .......................................... shortages that require curtailment of full-service demands. Mandatory allocations are avoided to the extent practicable, however, in the event of an extreme shortage, an allocation plan will be adopted in accordance with the principles of the WSDM Plan and Metropolitan's Water Supply Allocation Plan, as was implemented in 2010 and 2011, until recently rescinded by Metropolitan. Metropolitan Water Surplus and Drought Management Plan (WSDM) In 1999, Metropolitan in conjunction with its member agencies developed the WSDM Plan.68 This plan addresses both surplus and shortage contingencies, The WSDM Plan will guide management of regional water supplies to achieve the reliability goals of Southern California's IRP. The IRP sought to meet long-term supply and reliability goals for future water supply planning. The WSDM Plan's guiding principle is to minimize adverse impacts of water shortage and ensure regional reliability. From this guiding principle come the following supporting principles: • Encourage efficient water use and economical localresource programs; • Coordinate operations with member agencies to make as much surplus water as possible available for use in dry years; • Pursue innovative transfers and banking programs to secure more imported water for use in dry years; and • Increase public awareness about water supply issues. The WSDM Plan guides the operations of water resources (local resources, Colorado River, State Water Project, and regional storage) to ensure regional reliability. it OJ I identifies the expected sequence of resource management actions Metropolitan will take during surpluses and shortages of water to minimize the probability of severe shortages that require curtailment of full-service demands. Mandatory allocations are avoided to the extent practicable; however, in the event of an extreme shortage Metropolitan's Water Supply Allocation Plan will be implemented. The WSDM Plan distinguishes beiween Surpluses, Shortages, Severe Shortages, and Extreme,Shortages. Within the WSDM Plan, these terms have specific. meaning relating to Metropolitan's capability to deliver water to the City as described below: • Surplus: Metropolitan can meet full-service and interruptible program demands, and it can deliver water to local and regional storage. • Shortage: Metropolitan can meet full-service demands and partially meet or fully meet interruptible demands, using stored water or water transfers as necessary. 6" A copy of Metropolitan's WSDM Plan can be found in Appendix A.4 to the agencies November 2010 RUWMP at: httL,:i"lw\vv,,.n-,�%,-cih2o.coiii,ii-n�vdli2q, .,i_,es,,vo w 'I J 10-pdf 1113 -453- Item 16. - 123 City of Huntington Beach Section 8 2010 Urban Water Mona e nent Plan • Severe Shortage: Metropolitan can meet full-service demands only by using stored water, transfers, and possibly calling for extraordinary conservation. In a Severe Shortage, Metropolitan may have to curtail Interim Agricultural Water Program (IAWP)deliveries in accordance with IAWP. • Extreme Shortage: Metropolitan must allocate available supply to full-service customers. The WSDM Plan also defines five surplus management stages and seven shortage management stages to guide resource management activities. Each year, Metropolitan will consider the level of supplies available and the existing levels of water in storage to determine the appropriate management stage for that year. Each stage is associated with specific resource management actions designed to: 1) avoid an Extreme Shortage to the maximum extent possible; and 2) minimize adverse impacts to retail customers should an "Extreme Shortage" occur. The current sequencing outlined in the WSDM Plan reflects anticipated responses based on detailed modeling of Metropolitan's existing and expected resource mix. This sequencing may change as the resource mix evolves. WSDM Plan Shortage Actions by Shortage Stage When Metropolitan must make net withdrawals from storage, it is considered to be in a shortage condition. However, under most of these stages, it is still able to meet all end- use demands for water. The following summaries describe water management actions to be taken under each of the seven shortage stages. • Shortage Stage 1 — Metropolitan may make withdrawals from Diamond Valley Lake. • Shortage Stage 2-Metropolitan will continue Shortage Stage 1 actions and may draw from out-of-region groundwater storage. • 'Shortage Stage 3—Metropolitan will continue Shortage Stage 2 actions and may curtail or temporarily suspend deliveries to Long Term Seasonal and Replenishment Programs in accordance with their discounted rates. • Shortage Stage 4—Metropolitan will continue Shortage Stage 3 actions and may draw from conjunctive use groundwater storage (such as the North Las Posas program)and the SWP terminai reservoirs. • Shortage Stage 5 — Metropolitan will continue Shortage Stage 4 actions. Metropolitan's Board of Directors may call for extraordinary conservation through a coordinated outreach effort and may curtail Interim Agricultural Water Program deliveries in accordance with their discounted rates. In the event of a call for extraordinary conservation, Metropolitan's Drought Program Officer will coordinate public information activities with member agencies and monitor the effectiveness of ongoing conservation programs. The Drought Program Officer will implement monthly reporting on conservation program activities and progress and will provide quarterly estimates of conservation water savings. Item 16. - 124 11B _ _54- City of Huntington Beach 010 Urban Water Management Plan Section 8 .... ...... ............----------------- ------ ......................_.......__.__ -1--l- • Shortage Stage 6—Metropolitan will continue Shortage Stage 5 actions and may exercise any and all water supply option contracts and/or buy water on the open market either for consumptive use or for delivery to regional storage facilities for use during the shortage. • Shortage Stage 7 — Metropolitan will discontinue deliveries to regional storage facilities, except on a regulatory or seasonal basis, continue extraordinary conservation efforts, and implement its Water Supply Allocation Plan. The overriding goal of the WSDM Plan is to never reach Shortage Stage 7, an Extreme Shortage. Reliability Modeling of the WSDM Plan Using a technique known as "sequentially indexed Monte Carlo simulation," Metropolitan undertook an extensive analysis of system reservoirs, forecasted demands, and probable hydrologic conditions to estimate the likelihood of reaching each Shortage Stage through 2010. The results of this analysis demonstrated the benefits of coordinated management of regional supply and storage resources. Expected occurrence of a Severe Shortage is four percent or less in most years and never exceeded six percent; equating to an expected shortage occurring once every 17 to 25 years. An Extreme Shortage was avoided in every simulation run. Metropolitan's Water Supply Allocation Plan69 Metropolitan adopted its Water Supply Allocation Plan (WSAP) following critically dry conditions affected all of Metropolitan's main supply sources in 2007. Those dry conditions coupled with a ruling in the Federal Courts in August 2007 providing protective measures for the 'Delta smelt in the Sacramento-San Joaquin River Delta, brought uncertainty about future pumping operations from the State Water Project. Metropolitan worked jointly with the member agency managers and staff to develop a Water Supply Allocation Plan (Plan)to address such needs. The plan that was eventually adopted includes specific formulas for calculating member agency supply allocations and the key implementation elements needed for administering an allocation should a shortage be declared. The adopted allocation formulas seek to balance the impacts of a shortage at the retail level while maintaining equity on the wholesale level, and takes into account growth, local investments, changes in supply conditions and the beneficial impacts of non-potable recycled water use and the implementation of conservation savings programs. The adopted formulas are calculated in three steps: (1) base period calculations; (2) allocation year calculations, and (3) supply allocation calculations. These steps are described in further detail below. 69 Information presented in this section has been extracted from Metropolitan's Water Supply Allocation Plan, June 2009, a copy of which can be found in Appendix A.4 to the agencies November 2010 RUWMP at: http:.',,"w,,,,-w,iiiwdii2o.ct)iii,"niwdh2o.," 1113 -455- Item 16. - 125 City of Huntington Beach Section 8 2010 Urban Water Management ana£gement Flan • Step 1: Base Period Calculations: The first step in calculating a water supply allocation is to estimate water supply and demand using a historical base period with established water supply and delivery data. The base period for each of the different categories of demand and supply is calculated using data from the three most recent non-shortage years (base period), which for the current allocation were 2004-2006. The calculations take into account various factors including local supplies, wholesale supplies, retail supplies, demands, in-lieu deliveries, agricultural deliveries, conservation achieved and conservation rate structures. • Step 2: Allocation Year Calculations: The next step ,in calculating the water supply allocation is estimating water needs in the allocation year. This is done by adjusting the base period estimates of retail demand for population or economic growth and changes in local supplies. A number of factors are taken into consideration in this step including: .(1) allocation year retail demands; (2) allocation year local supplies; and(3)allocation year wholesale demands. • Step 3: Supply Allocation Calculations: The final step is calculating the water supply allocation for each member agency based- on the allocation year water needs identified in Step 2. Again, several elements are considered at this stage including: (1) regional shortage levels; (2) regional shortage percentages; (3) extraordinary increased production adjustments; (4) wholesale minimum allocations; (5)maximum retail impact adjustments; (6) interim agricultural water program reductions; (7) conservation demand hardening credits; (8) municipal and industrial allocations; and (9)total allocation The Allocation Plan takes effect when a regional shortage is declared by Metropolitan's Board of Directors. The allocation period covers twelve consecutive months, from July of a given year through the following June (this period was selected to minimize the impacts of varying SWP allocations and to provide member agencies with sufficient time to implement their outreach strategies and rate modifications). The Allocation Plan also allows for an appeals process to address any changes or corrections to an agency's'allocation. Appeals can be made to request adjustments for(1) erroneous historical data used in base period calculations; (2) unforeseen loss or gain in local supply; (3) extraordinary increases in local supply; (4) population growth rates; and (5) reviewing calculation of base period, allocation.year and supply allocation figures for consistency with the standards outlined in the Allocation Plan. The Allocation Plan also allows for enforcement through a penalty rate structure. Penalty rates and charges will only be assessed to the extent that an agency's total annual usage exceeds its total annual allocation. Any funds collected will be applied towards investments in conservation and local resources development within the service area of the member agency by which the penalties are incurred. No billing or assessment of penalty rates will take place until the end of the twelve-month allocation period.

Health and Safety Requirements The primary goal of the City's water system is to preserve the health and safety of its personnel and the public. Meeting this goal is a continuous function of the system - before, during and after a disaster or water shortage. Fire suppression capabilities will continue to be maintained during any water shortage contingency stage. Some water needs are more immediate than others. The following list of public health needs and the allowable time without potable water is a guideline and will depend on the magnitude of the water shortage: • Hospitals-continuous need • Emergency shelters-immediate need • Kidney dialysis-24 hours • Drinking water-72 hours • Personal hygiene,waste disposal-72 hours Based on commonly accepted estimates of interior residential water use in the United States, Table 8.2-1 indicates per capita health and safety water requirements. During the initial stage of a shortage, customers May adjust either interior and/or outdoor water use to meet the voluntary water reduction goal.

Priority by Use Conditions prevailing in the City of Huntington Beach area require that available water resources be put to maximum beneficial use to the extent possible. The waste, unreasonable use, or unreasonable method of use, of water should be prevented and water conservation and water use efficiency should be encouraged with a view toward maximizing reasonable and beneficial use thereof in the interests of the people of the City and for the public welfare. Preservation of health and safety will be a top priority for the City. 8.3 ESTIMATE OF MINIMUM SUPPLY FOR NEXT THREE YEARS Based on their 2010 RUWMP, Metropolitan projects 100 percent reliability for full- service demands through the year 2035. Additionally, through a variety of groundwater reliability programs conducted by OCWD and participated in by the City, local supplies are projected to be maintained at demand levels. The City anticipates the ability to meet water demand through the next three years based on the driest historic three-years as shown in Table 8.3-1. The multiple dry year demand for year 2013 from Table 5.2-3 is only 36,250 AFY and supply is estimated at well over 38,000 AFY as shown below.

Both sources of water are vitally important to the City. MWDOC and OCWD are implementing water supply alternative strategies for the region and on behalf of its member agencies to insure available water in the future and during shortages. Supplemental water supplies are discussed in Section 4, Water Reliability Planning. Supplies discussed include regionally beneficial programs, including management of water system pressures and peak demands, water exchanges or transfers, conjunctive use programs, recycled water projects and desalination. These options include programs for expanded local supplies. Additional actions to manage limited supplies would include ------------------ 8-8 Item 16. - 128 1113 -458- City or Huntington Beach 2010 Urban Water Management Plan Section 8 ......................... ........ both operational and demand management measures, encompassing alternative rate structures, distribution of water use efficiency devices, and enhanced school education and public information. The MWDOC 2010 RUWMP and Metropolitan RUWMP further discusses programs by MWDOC, OCWD and Metropolitan for the benefit of the region and their member agencies, including the City of Huntington Beach. 8.4 CATASTROPHIC SUPPLY INTERRUPTION PLAN Water Shortage Emergency Response A water shortage emergency could be the result of a catastrophic event such as result of drought, failures of transmission facilities, a regional power outage, earthquake, flooding, supply contamination from chemical spills, or other adverse conditions. The City maintains and exercises a comprehensive Emergency Management Program for such emergencies including Water Shortage Emergency Response. The Utilities,Division of the Public Works Department is responsible for water operations and maintenance as well as implementation of the City's Emergency Management Plan. The plan describes the organizational and operational policies-and procedures required to meet the needs of sufficient water for firefighting operations and safe drinking water and provides a system for organizing and prioritizing water repairs. It also cites authorities and specifies the public and private organizations responsible for providing water service. The Public Works Department will operate under normal operating procedures until a situation is beyond its control. This includes implementation of any allocation plan passed through by MWDOC for,Metropolitan, and water shortage contingency plans of OCWD. If the situation is beyond the Utilities Division's control, the Division Operations Center (DOC) may be activated to better manage the situation. If the situation warrants, the City Emergency Operations Center (EOC) may be activated at which time a water representative will be sent to the EOC to coordinate water emergency response with all other City department's emergency response. The representative sent to the EOC is caned the Water Tactical 01fificer. In the event the EOC is activated, the City management Policy Group will set priorities. When the EOC is activated, the DOC will take its direction from the EOC. An EOC Action Plan will be developed in the EOC that will carry out the policies dictated by the Policy Group. The DOC will use the EOC Action Plan in determining its course of action. Coordination between the DOC and the EOC will be accomplished by the Utilities Manager (located in the DOC) and the Water Tactical Officer(located in the EOC)under the direction of the Public Works Chief(located in the EOC). I 1B -459- Item 16. - 129 City of Hurdincn'on Beach Section 8 2010 Urban Water Manageanent Plan If the situation is beyond the City's control, additional assistance will be sought through coordination with the Water Emergency Response Organization of Orange County. Water Emergency Response Organization of Orange County(WEROC) The City of Huntington Beach Public Works Department actively participates in the Water Emergency Response Organization of Orange County (WEROC). WEROC performs coordination of information and mutual-aid requests among water agencies, and conducts disaster training exercises for the Orange County water community and with Metropolitan. In 1983, the Orange County water community developed a,Water Supply Emergency Preparedness Plan to respond effectively to disasters impacting the regional water distribution system. This plan was jointly funded by three regional water agencies: Coastal Municipal Water District, MWDOC, and OCWD, with the support and guidance from the Orange County Water Association (OCWA). The collective efforts of these agencies resulted in the formation of the countywide WEROC, which is unique in its ability to provide a single point of contact for water,representation in Orange County during a disaster. The MWDOC 2010 Regional Urban Water Management Plan presents further details of WEROC. Additional emergency services available to the City of Huntington Beach in the State of California include the Master Mutual Aid 'Agreement, California Water Agencies Response Network (WARN) and Plan Bulldozer. The Master Mutual Aid Agreement includes all public agencies that have signed the agreement and is planned out of the California Office of Emergency Services. WARN includes all public agencies that have signed the related agreement to provide mutual aid. It is managed by a State Steering Committee. Plan Bulldozer provides,mutual aid for construction equipment to any public agency for the initial time of disaster when danger to life and property exists. 8.5 PROHIBITIONS,"PENALTIES, AND CONSUMPTION REDUCTION METHODS As part of the City's Water-Management Program, water use regulations are set forth in Chapter 114.16 of the City's Municipal Code, as included in Appendix G. Some of the regulations included,apply to fires (fire hydrants), waste (improper fixtures), meters (use and location), violations, drawing into steam boilers, water sales outside of city, and cross-connections protection. Refer to Appendix G for the complete ordinance. Any violation of the City's Water Management Program, including waste of water and excessive use, is a misdemeanor. In addition to any other remedies the City may have for enforcement, service of water would be discontinued or appropriately limited to any customer who willfully uses water in violation of any provision of the ordinance. 8_1 0 Item 16. - 130 1113 -460- City of Huntington Beach 2010 Urban Water Management Plan Section 8 ------------ The City of Huntington Beach will follow the allocation plan guidelines of MWDOC who will follow the lead of Metropolitan once an extreme shortage is declared. This allocation plan will be enforced by Metropolitan as set forth in their Water Supply Allocation Plan (WSAP). MWDOC adopted a WSAP in January 2009, to allocate supplies at the retail level. The MWDOC WSAP uses a similar method and approach, when reasonable, to that of Metropolitan's WSAP. However, the MWDOC WSAP remains flexible to use an alternative approach when Metropolitan's method produces a significant unintended result for the MWDOC member agencies. Details of MWDOC's WSAP can be found in Section 5 or their 2010 RUWMP. The MWDOC WSAP follows the guidelines of Metropolitan's WSAP, as required to enforce consumption reductions up to a 50% reduction in water supply. The City would correspondingly implement the levels of its Water Management Program in concert with,,Metropolitan and MWDOC and impose surcharges or penalties in accordance with;its "ordinance on excessive use of water. 8.6 REVENUE AND EXPENDITURE IMPACTS AND MEASURES TO OVERCOME THOSE IMPACTS The City receives water revenue from a commodity charge,,,a fixed customer charge and 'the a capital surcharge. The rates have been designed to recover,I full cost of water service in the commodity charge. Therefore,',the &osi- of purchasing water and producing groundwater would decrease as the usage or sale bf water,ldecreases. Should an extreme shortage be declared and a large reduction in water sales "occurs for an extended period of z time, the Public Works' Department would re-examine its water rate structure and monitor projected expenditures. In the'event of a 501% reduction in water supply, the City will take action in congruence with, MWDOC to ensure adequate consumption reduction methods. In September 2003, MWDOC partnered with the Orange County Business Council and prepared a report, "Determining, the Value of Water Supply Reliability in Orange County, California." The study provides,insights into how to value water supply reliability by providing projected estimates of the economic impacts of different water shortages that could result in `Orange County. The study does not assess the likelihood of different disruptions to water supply, but instead estimates the economic impacts of the resulting water shortages if aparticular supply interruption occurs. Two types of shortages-were examined in the study—short-term emergency disruptions and multiple-year droughts. A range of scenarios was examined for both situations. Those scenarios were: • Emergency Disruptions: Water supply reductions of 20%,40%, 60% and 80% for 10, 20, 30, and 60 days. • Drought: Water supply reductions of 5% and 20% for one,two, and three years. The estimated economic impacts are separated into business impacts and residential impacts. Residential users are often required to reduce their water usage more than business customers during water shortages to help preserve the economic base of the 1113 -461- Item 16. - 131 City of Huntington Beach Section 8 2010 Urban Slater Management Plan area. In addition to residential and business impacts, this report also included an estimate of the value of landscape losses that would be expected during droughts, and a discussion of the impact of emergency outages on damages from firestorms due to a lack of water supply for firefighting. The study produced dollar estimates of economic impacts of given water shortages to both the business and residential sectors of three regions within Orange County. The water shortage scenarios analyzed included both short-term emergency disruptions (10 to 60 days in duration) and multiple-year drought situations (1 to 3 years). The three regions of the County analyzed were defined based on the availability of local supplies and the potential risk of supply reliability impacts. The results revealed that business impacts are larger than residential impacts. For short- term, emergency disruptions, the difference between business impacts and residential impacts varied depending on the magnitude and length of a shortage. For an 80% water loss in South Orange County for 60 days, business impacts are approximately five times as large as residential impacts. For a 20% water,loss in the_Basin, business impacts are approximately ten times as large as resident impacts: At low levels of water disruption, resident impacts more closely approximate business impacts. For example, the residential impacts from a 20% water loss for 10 days in South Orange County are about 75%of the business impacts from the same,disruption. For all of Orange County during an emergency outage that causes a 20% water supply shortfall and lasts from 401 to 60 days, the economic"impacts range from $0.4 to $3 billion. Employment losses were estimated at;,3,000 to 23,000 over the 10 to 60 days. For all of Orange County'during a drought that results in a 5% shortage to the Basin area and 20% shortage outside the,basin area for a I to 3 .year period, the economic impacts range from $15 to $43 billion. Employment losses were estimated at 75,000 to 225,000 over the one to three-year period., If shortages were to occur:,, • South Orange County would experience approximately 12% of the business and employment impacts, but 25% of the residential and landscape losses. South Orange County has.a higher dependence on imported water supplies and hence is more vulnerable to supply outages. • The Orange County Basin would experience 84% of the business impacts and 71% of the residential and landscape losses, but has a significant supply of water available from the groundwater basin and hence is somewhat insulated from imported water supply emergency disruptions. • Brea/La Habra area would experience about 3%of all impacts. Drought scenarios generally cause a higher level of impact than do emergency outages and exceed all but the worst-case emergency disruptions. The exception is a 60-day, 60% reduction in water supplies to the Basin business sector, which would exceed the impact 8-12 Item 16. - 132 1113 -462- City of Hunfinglon Beach 20 10 Urban Water Management Plan Section 8 ------------ ..................... of a year-long 5% drought in the Basin. (20% reduction in imported supply assuming a 70% BPP.) In most scenarios, about half of the business losses are in the manufacturing and service sectors. Employment losses are highest in services and retail throughout the County. The study provides extensive insight into the City's water reliability and water shortage contingency plan for planning for the future. The study also demonstrates the extensive importance to the City's water reliability and water shortage contingency plan for planning for the future. If such impacts occur in the residential and business community, the municipal community will be impacted correspondingly. Economic impacts to the community create economic impacts to the City revenue from water sales, among other City revenue sources. The City must and will continue to be, diligent in maintaining appropriate water rates and rate structure, and making reasonable adjustments as justified; maintaining sufficient water reserve funds; and managing expenses accordingly. 8.7 WATER SHORTAGE CONTINGENCY ORDINANCE In 1991, the City of Huntington Beach adopted by ordinance a comprehensive Water Management Program based upon the need to conserve water supplies and to avoid or minimize the effects of future shortage. A copy of the City's Water Management Program Ordinance, Chapter 14.18 of the,City Municipal Code, is included as Appendix G. Chapter 14.16 of the Municipal Code also establishes overall Water Use Regulations, including regulations for water meters. In addition, the City's Water Efficient Landscaping Ordinance, Chapter 14.52 of the City's Municipal Code is also included in Appendix G. 8.8 MECHANISMS TO DETERMINE REDUCTIONS IN WATER USE Under normal conditions, potable water production figures are recorded daily. Weekly and monthly reports are prepared and monitored. This data will be used to measure the effectiveness of any water shortage contingency stage that may be implemented. As stages of water shortage are declared by Metropolitan and MWDOC, the City of Huntington Beach will follow implementation of those stages and continue to monitor water demand levels. It is not until Shortage Stage 5 that Metropolitan may call for extraordinary conservation. During this stage, Metropolitan's Drought Program Officer will coordinate public information activities with MWDOC and monitor the effectiveness of ongoing conservation programs. Monthly reporting on estimated conservation water savings will be provided. The City will participate in monthly member agency manager meetings with both MWDOC and OCWD to monitor and discuss monthly water allocation charts. This will enable the City to be aware of import water use on a timely basis as a result of specific actions taken responding to the City's Water Shortage Contingency Plan. I I B 463- Item 16. - 133 City of Huntington Beach Section 8 2010 Urban Water Management Plan .................. During Metropolitan's fiscal year 2009-10 and 2010-11 a Level 2 WSAP has been in effect, which in essence called for reduction levels of 15 percent in water use by its member agencies. Metropolitan's fiscal year commences July I and ends June 30. These allocations were passed on by MWDOC and during fiscal year 2009-10 the City reduced its demand by 6.9% from FY 08-09 and based on the first half of fiscal year 2010-11 is on track for an additional 5% reduction from 2009-10. Therefore, the City has responded favorably to these allocation requirements indicating that they are effective in making water supplies last during extended drought periods. 88-14 Item 16. - 134 11 B -464- City of Huntington Beach 2010 Urban Water Management Plan Section 9 ...................... .......... 9 WATER RECYCLING/URBAN RUNOFF 9.1 RECYCLED WATER IN SOUTHERN CALIFORNIA The Southern California region, from Ventura to San Diego, discharges over I billion gallons (1.1 million AFY) of treated wastewater to the ocean each day. These discharges represent a potentially reliable and drought-proof water source, which if treated appropriately and utilized for irrigation and other purposes, could greatly reduce the region's and the City's reliance on imported water. As technological improvements continue to reduce treatment costs, and as public perception and acceptance continue to improve, numerous reuse opportunities may surface in the coming years. Recycled water is already a critical component of the California water picture and should continue to be so in future years because it is not subject to drought induced cutbacks. 9.2 COORDINATION OF RECYCLED WATER IN THE CITY SERVICE AREA Currently, the City does not utilize or serve directly applied recycled water to any of its customers or for municipal purposes. However, the City does receive a partial credit for recycled water produced by the Joint OCWD/OCSD Groundwater Replenishment System (GWRS) from wastewater generated within the City of Huntington Beach. As previously noted, the City produces a majority of its water supply from the Orange County Groundwater Basin (Basin). In addition to the GWRS recycled water credit, OCWD also utilizes recycled water generated from Orange County Sanitation District's (OCSD) treatment -,facilities to protect the Basin through the operation of seawater intrusion barriers and groundwater recharge basins. The City, therefore, indirectly benefits from this regional use of recycled water. The regional projects are discussed later in this section. 9.3 COLORED WATER (WELL NO. 8) While not technically a recycled water project, the City is investigating the possibility of utilizing Well No. 8 water, which was removed from service as a potable water supply due to water quality issues, as a source of irrigation water. This project is currently in the City's FY 2010/11 Capital Improvement -Program (CIP), including modification of the wellhead and installation of various improvements to enable it to be used for irrigation of multiple City-owned parks, including Central Park along Goldenwest Street. This is not technically a new source of supply since it will count towards the City's BPP as far as OCWD is concerned. However, as the utilization of Well No. 8 is increased, the poorer water quality water should be replaced with higher quality groundwater resulting in improved water quality in this area of the Basin. This additional source also increases the reliability of the City's supply. 1113 -465- Item 16. - 135 City of Ncentington Beach .Section 9 20 10 Urban Water Management Flan 9.4 URBAN RUNOFF (TALBERT LAKE DIVERSION PROJECT) The capture of urban runoff and reuse is another source of water supply currently being investigated by the City to provide added supply reliability. The Talbert Lake Diversion Project is a Santa Ana Regional Water Quality Control Board-approved Supplemental Environmental Project (SEP) involving the construction of a natural treatment system in the northeastern corner of Central Park in Huntington Beach, on the eastern side of Goldenwest Street. The proposed project would divert up to 3 million gallons per day (mgd) of dry weather flows from the East Garden Grove Wintersburg Channel (EGGWC) into a newly constructed treatment wetlands system for water quality improvement purposes. Project components include the construction of a diversion structure such as a rubber dam within the EGGWC to divert dry weather flows either into an existing water line in Goldenwest Street, or the existing storm drain system within Gothard Street, for transport to the newly constructed treatment wetlands within Central-Park. This water would then be pumped out of the lake maintaining it at the appropriate_water level and utilized to irrigate parks and landscaping along Goldenwest Street. The Talbert Lake Diversion Project is currently in the City's FY 2010/11 Capital Improvement Program (CIP). Design of project is essentially complete at this point, and the City is in the process of procuring funding for construction of this project. The project would provide a variety of benefits to the environment and public at large, including protection of the beneficial uses of coastal`waters; creation and enhancement of environmental habitats; educational awareness; potential groundwater recharge; potential seawater barrier enhancements; enhanced recreational experiences; and an additional year-round irrigation supply helping preserve'the City's potable water supply. 9.5 WASTEWATER COLLECTION AND TREATMENT IN THE CITY SERVICE AREA Wastewater from the City's water service area is collected and treated by OCSD. The City operates and maintains the localized sewer collection pipelines that feed into OCSD's trunk sewer system. The City of Huntington Beach sewer system includes approximately 385 miles of sewer lines, 10,000 manholes and 28 lift stations. OCSD operates the third largest.wastewater system on the west coast, consisting of dearly 600 miles of trunk sewers and 200 miles of subtrunk sewers, two regional treatment plants, and an ocean disposal system. The OCSD sewerage system collects wastewater through an extensive system of gravity flow sewers, pump stations, and pressurized sewers (force mains). The sewer system consists of 12 trunk sewer systems ranging in size from 12 to 96 inches in diameter. Orange County Sanitation Districts (OCSD) Treatment Plants As previously noted, OCSD's Reclamation Plant No. I is located in the City of Fountain Valley about 4 miles northeast of the ocean, adjacent to the Santa Ana River. The plant provides advanced primary and secondary treatment and supplies secondary treatment j y Item 16. - 136 1113 --466_ City of Huntington Beact? 20 10 Urban Water Management Plan Section 9 ----------------- ........... ........... water to OCWD which further treats and distributes the water for various uses, including irrigation, groundwater recharge, and operation of coastal seawater barrier system. The treatment process at Reclamation Plant No. I includes secondary treatment through an activated sludge system. This plant receives raw wastewater from six major sewer pipes, often called "interceptors" or "trunk lines." The secondary effluent is either blended with the advanced primary effluent and routed to the ocean disposal system, or is sent to the OCWD facilities for advanced treatment and recycling at the GWRS Treatment Plant. The solid materials removed in the treatment systems are processed in large tanks to facilitate, natural decomposition. Half of the material is converted to methane, which is burned as fuel in the energy recovery system, and the remaining solids are used as a soil amendment or fertilizer for agricultural crops. OCSD's Treatment Plant No. 2 is located in the City of Huntington Beach adjacent to the Santa Ana River and about 1,500 feet from the ocean. This plant providesa mix of advanced primary and secondary treatment. The plant receives raw wastewater through five major sewers. The treatment process is similar to Plant No. 1. Approximately 33 percent of the influent receives secondary treatment through an activated sludge system, and all of the effluent is discharged to the ocean disposal,system. The portion of OCSD's treated wastewater that is not recycled or used for seawater intrusion protection is discharged through a 120-inch outfall at a depth of approximately 200 feet below sea level and nearly five miles offshore from the Santa Ana River. Its high tide hydraulic capacity is 480 mgd. A 18-inch standby outfall, stretching approximately one mile from shore, is used for emergency purposes. Current capacity for Reclamation Plant No. I is,218 million gallons per day (mgd) of wastewater, with an average daily flow of 120 mgd. Current capacity for Plant No. 2 is 168 mgd of wastewater, with an average flow of 144 mgd.70 The City provides significant amount of.,wastewater to OCSD's plants. The quantities of wastewater generated are generally"proportional to the population and the water use in the service area. Wastewater flows generated within the City of Huntington Beach are currently estimated at between 24,600 and:26,000 AFY by OCSD.7 1 However, due to the economy and water conservation, these figures are believed to be over estimated. Wastewater flows are generally proportional to water usage, which means that as per capita water usage declines over past usage figures, wastewater flows will also decline somewhat, but with some minimal increase due to population increases as referenced in Section I of this UWMP. 70 MWDOC 2010 Regional Urban Water Management Plan. 71 Calculated by using unit flow coefficient for 2010 extracted from Tables 3.1 and 3.5 in the OCSD Collection System Model and Strategic Plan Update,April 2006,prepared by MWH;report is available on OCSD website at: ............ 1113 -467- Item 16. - 137 City of Huntington Beach Section 9 2010 Urban Water Managernent Plan .......... 9.6 REGIONAL RECYCLED WATER Since Huntington Beach depends on groundwater for at least 62 percent of its total water supply, the City supports the efforts of the regional water management agencies to utilize recycled water in Orange County. Recycled water is used to protect the Orange County Groundwater Basin through recharge and prevention of saltwater intrusion. Recycled water in Orange County is also used to irrigate crops, golf courses, parks, schools, business landscapes, residential lawns, as well as for some industrial uses thus offsetting potable water demands. In the 2007-08 water year, almost 36,000 AFY of recycled water was applied by water retailers in the County.72This amount does not include recycled water of up to 72,000 AFY which is currently being produced by GWRS. The regional projects planned or currently used to provide recycled water are discussed in the following sections. Green Acres Project(GAP) OCSD produces recycled water year round for OCWD's Green Acres Project (GAP), providing recycled water for industrial customers and landscape irrigation in the cities of Santa Ana, Fountain Valley, Costa Mesa, and Newport Beach. The GAP has the capacity to treat and distribute up to 7.5 mgd of recycled water. At one time, GAP served a single customer(the County of Orange) within the City of Huntington Beach, but that service is no longer active and there are no plans to serve the City in the near future. Water Factory 21 As previously noted, Water Factory 21 was taken off-line in 2004 due to the pending construction of the GWRS Plant. Water Factory 21 had been used by OCWD for almost 30 years prior to that time to produce recycled water for injection into the groundwater basin to protect,against seawater intrusion.,, Water Factory 21 purified approximately 4 mgd of recycled water and deep well water. This blended water supplied a hydraulic barrier,system that consisted of a series of injection wells, located approximately four miles inland, to produce a, fresh water mound within the groundwater aquifer to block further inland intrusion of seawater. OCVMIOCSD Groundwater Replenishment System (GWRS) Groundwater basin recharge is the single largest use of recycled water in Orange County. As previously noted, the GWRS project was placed into operation in 2008 to help address that need. GWRS is a water supply project designed to ultimately reuse approximately 130,000 AFY of advanced treated wastewater. The GWRS Plant currently produces up to 72,000 AFY. Plant expansion, providing the ability to produce 101,000 AFY is currently under design. 72 Per the Center for Demographic Research,Cal State Fullerton,March 2009 Profile entitled Water Use in Orange County,available here:hy-- "-%N 14n],pdt 9-4 Item 16. - 138 1113 -468- City of Huntington Beach 2010 Urban Water Management Plan Section 9 -—--------- The GWRS project provides a new source of reliable, high quality, low salinity water to replenish the Basin and expand the existing seawater intrusion barrier. The GWRS supplements existing water supplies, and provides a new, cost-effective and reliable source of water to recharge the Basin, protect the Basin from further degradation due to seawater intrusion, and augment the supply of recycled water for irrigation and industrial use. The GWRS is comprised of three major components: (1) Advanced Water Purification Facilities (AWPF) and pumping stations; (2) a major pipeline connecting the treatment facilities to existing recharge basins; and (3) expansion of an existing seawater intrusion barrier. The GWRS takes secondary, treated municipal wastewater from the OCSD Treatment Plant No. I in Fountain Valley and further_cleans,this water to levels that exceed current drinking water standards. A portion of the treated"product water is then pumped upstream via a,major conveyance pipeline generally paralleling the Santa Ana River to the OCWD spreading basins where it is allowed to percolate into the Orange County Groundwater Basin. The treated water is also be injected into the ground to create an expanded seawater intrusion barrier. 9.7 POTENTIAL USES OF RECYCLED WATER, While the City recognizes the potential uses of recycled water in its community, such as landscape irrigation, parks, industrial and other uses, the OCWD does not have the recycled water infrastructure at this time to support pport th& direct use of recycled water in Huntington Beach. Initial development in Huntington Beach generally began in the 1950s and the community is essentially built-out at this time. Various analyses to determine the cost-effectiveness of constructing recycled water infrastructure have been conducted over the years,but none have been show to be beneficial. That being the case, the City has instead opted to support, encourage and contribute to the continued developm&ht of recycled water and potential uses throughout the region through such projects as GWRS. 9.8 PROJECTED AND POTENTIAL USES OF RECYCLED WATER The Cltv's 2000 UWMP -01 p� Jected that 'by 2005 recycled water from OCWD's Green Acres Project would be available to the City of Huntington Beach for irrigation use. The infrastructure required to implement that use has not yet been constructed and it is not anticipated that such infrastructure will be in place in the near future. Therefore, the City does not project any recycled water use for subsequent years, and currently does not utilize or serve directly applied recycled water to any of its customers or for municipal uses. 9.9 ENCOURAGING RECYCLED WATER USE Studies of water recycling opportunities within southern California provide a context for promoting the development of water recycling plans. It is recognized that broad public acceptance of recycled' water requires continued education and public involvement. I I B -469- Item 16. - 139 City off untington Beach Section 9 2010 Urban Water Management Plan However, planning for most of the recycled water available is being directed toward replenishment of the Basin and improvements in groundwater quality. As a user of groundwater, the City supports the efforts of OCWD and OCSD to utilize recycled water as a primary resource for groundwater recharge in Orange County. Public Education The City continues to participate in MWDOC's public education and school education programs, which include extensive learning programs on water recycling. MWDOC's water use efficiency public information programs are a partnership with agencies throughout the county. MWDOC staff reaches out to area residents including those in the City, through a variety of public information programs. These programs include information on present and future water supplies, demands for a suitable quantity and quality of water, including recycled water, and the importance of implementing water efficient techniques and behaviors. Through MWDOC, water education- programs have reached ihousands of students with grade-specific programs that include inf6rmation on recycled water. Between October 2009 and April 2010, school education presentations were made at 19 public and private schools in Huntington Beach. These programs were attended by over 7,300 students. Programs scheduled at City schools during,the 2010-11 academic year, will reach out to an additional 8,000 students.73 1 Financial Incentives The implementation of recycled water projects involves a substantial upfront capital investment for planning,studies, environmental impact reports, engineering design and construction before there is any,recycled water to market. For some water agencies, these capital costs exceed the short-term expense of purchasing additional imported water supplies from Metropolitan. The establishment of new supplemental funding sources through federal, state and regional programs now provide significant financial incentives for local agencies to develop and make use of recycled water. Potential sources of funding include federal, state and loco':_ finding opportunities_ These, -.6inding sources include the USBf'\, California Proposition I") Water Bond, and Metropolitan's Local Resources Program. These funding opportunities may be sought by the City or possibly more appropriately by regional agencies. The City will continue to support seeking funding for regional water recycling projects and programs. 9.10 OPTIMIZING RECYCLED WATER USE In Orange County, the majority of recycled water is used for recharging the Basin, irrigating golf courses, parks, schools, business and communal landscaping. However, future recycled water use can increase by requiring dual piping in new developments, 73 Information on MWDOC's school education program including specific data on schools within Huntington beach can be accessed at: Item 16. - 140 1113 -470- City of Huntington Beach 2010 Urban Water Management Plan Section 9 ....... ........ retrofitting existing landscaped areas and constructing recycled water pumping stations and transmission mains to reach areas far from the treatment plants. Gains in implementing some of these projects have been made throughout the county; however, the additional costs, large energy requirements and required infrastructure, make such projects very expensive to pursue. To optimize the use of recycled water, cost/benefit analysis must be conducted for each potential project. Once again, this brings discussion about the technical and economic feasibility of a recycled water project, which in turn, requires a relative comparison to alternative water supply'options. For the City, analysis has shown capital costs exceed the short-term expense of purchasing additional imported water supplies from Metropolitan. Except for some possible future limited irrigation expansion, it is not anticipated that direct reuse projects will be pursued by the City. The City will continue to conduct cost/benefit analysis when feasible for recycled water projects, and seek creative solutions and a balance to recycled water use, in coordination with OCWD, Metropolitan and other cooperative agencies.

This part shall be known and may be cited as the"Urban Water Management Planning Act." 10610.2. (a)The Legislature finds and declares all of the following: (1)The waters of the state are a limited and renewable resource subject to ever-increasing demands. (2)The conservation and efficient use of urban water supplies are of statewide concern; however,the planning for that use and the implementation of those plans can best be accomplished at the local level. (3)A long-term, reliable supply of water is essential to protect the productivity of California's businesses and economic climate. (4)As part of its long-range planning activities, every urban water supplier should make every effort to ensure the appropriate level of reliability in its water service sufficient to meet the needs of its various categories of customers during normal, dry, and multiple dry water years. (5)Public health issues have been raised over a number of contaminants that have been identified in certain local and imported water supplies. (6) implementing effective water management strategies, including groundwater storage projects and recycled water projects, may require specific water quaiity and salinity targets for meeting groundwater basins water quality objectives and promoting beneficial use of recycled water. (7)Water quality regulations are becoming an increasingly important factor in water agencies'selection of raw water sources, treatment alternatives, and modifications to existing treatment facilities. (8)Changes in drinking water quality standards may also impact the usefulness of water supplies and may ultimately impact supply reliability. (9)The quality of source supplies can have a significant impact California Urban Water Management Planning Act Page 1 2010 1 l -4`/5- Item 16. - 145 on water management strategies and supply reliability. (b)This part is intended to provide assistance to water agencies in carrying out their long-term resource planning responsibilities to ensure adequate water supplies to meet existing and future demands for water. 10610.4. The Legislature finds and declares that it is the policy of the state as follows: (a)The management of urban water demands and efficient use of water shall be actively pursued to protect both the people of the state and their water resources. (b)The management of urban water demands and efficient use of urban water supplies shall be a guiding criterion in public decisions. (c)Urban water suppliers shall be required to develop water management plans to actively pursue the efficient use of available supplies. WATER CODE SECTION 10611-10617 10611.

California Urban Water Management Planning Act Page 15 2010 t IB -489- Item 16. e 159 Senate Bill No.7 CHAPTER 4 An act to amend and repeal Section 10631.5 of, to add Part 2.55 (commencing with Section 10608) to Division 6 of, and to repeal and add Part 2.8(commencing with Section 10800)of Division 6 of,the Water Code, relating to water. [Approved by Governor November 10,2009.Filed with Secretary of State November 10,2009.] LEGISLATIVE COUNSEL'S DIGEST SB 7,Steinberg.Water conservation. (1) Existing law requires the Department of Water Resources to convene an independent technical panel to provide information to the department and the Legislature on new demand management measures, technologies, and approaches. "Demand management measures" means those water conservation measures,programs,and incentives that prevent the waste of water and promote the reasonable and efficient use and reuse of available supplies. This bill would require the state to achieve a 20%reduction in urban per capita water use in California by December 31, 2020. The state would be required to make incremental progress towards this goal by reducing per capita water use by at least 10%on or before December 31,2015.The bill would require each urban retail water supplier to develop urban water use targets and an interim urban water use target,in accordance with specified requirements. The bill would require agricultural water suppliers to implement efficient water management practices. The bill would require the department,in consultation with other state agencies,to develop a single standardized water use reporting form. The bill, with certain exceptions, would provide that urban retail water suppliers, on and after July 1,2016, and agricultural water suppliers,on and after July 1,2013,are not eligible for state water grants or loans unless they comply with the water conservation requirements established by the bill.The bill would repeal,on July 1,2016, an existing requirement that conditions eligibility for certain water management grants or loans to an urban water supplier on the implementation of certain water demand management measures. (2) Existing law,until January 1, 1993,and thereafter only as specified, requires certain agricultural water suppliers to prepare and adopt water management plans. This bill would revise existing law relating to agricultural water management planning to require agricultural water suppliers to prepare and adopt agricultural water management plans with specified components on or before December 31,2012,and update those plans on or before December 93 Item 16. - 160 11B -490- Ch.4 —2— 31, 2015, and on or before December 31 every 5 years thereafter. An agricultural water supplier that becomes an agricultural water supplier after December 31,2012,would be required to prepare and adopt an agricultural water management plan within one year after becoming an agricultural water supplier.The agricultural water supplier would be required to notify each city or county within which the supplier provides water supplies with regard to the preparation or review of the plan. The bill would require the agricultural water supplier to submit copies of the plan to the department and other specified entities.The bill'would provide that an agricultural water supplier is not eligible for state water grants or loans unless the supplier complies with the water management planning requirements established by the bill. (3)The bill would take effect only if SB 1 and SB 6 of the 2009-10 7th Extraordinary Session of the Legislature are enacted and become effective. The people of the State of California do enact as follows: SECTION 1. Part 2.55 (commencing with Section 10608)is added to Division 6 of the Water Code,to read: PART 2.55. SUSTAINABLE WATER USE AND DEMAND REDUCTION CHAPTER 1. GENERAL DECLARATIONS AND POLICY 10608. The Legislature finds and declares all of the following: (a) Water is a public resource that the California Constitution protects against waste and unreasonable use. (b) Growing population, climate change, and the need to protect and grow California's economy while protecting and restoring our fish and wildlife habitats make it essential that the state manage its water resources as efficiently as possible. (c) Diverse regional water supply portfolios will increase water supply reliability and reduce dependence on the Delta. (d) Reduced water use through conservation provides significant energy and environmental benefits, and can help protect water quality, improve streamflows,and reduce greenhouse gas emissions. (e) The success of state and local water conservation programs to increase efficiency of water use is best determined on the basis of measurable outcomes related to water use or efficiency. (f) Improvements in technology and management practices offer the potential for increasing water efficiency in California over time,providing an essential water management tool to meet the need for water for urban, agricultural,and environmental uses. (g) The Governor has called for a 20 percent per capita reduction in urban water use statewide by 2020. 93 1113 -43 1- Item 16. - 161 —3— Ch.4 (h) The factors used to formulate water use efficiency targets can vary significantly from location to location based on factors including weather, patterns of urban and suburban development, and past efforts to enhance water use efficiency. (i) Per capita water use is a valid measure of a water provider's efforts to reduce urban water use within its service area.However,per capita water use is less useful for measuring relative water use efficiency between different water providers.Differences in weather,historical patterns of urban and suburban development, and density of housing in a particular location need to be considered when assessing per capita water use as a measure of efficiency. 10608.4. It is the intent of the Legislature,by the enactment of this part, to do all of the following: (a) Require all water suppliers to increase the efficiency of use of this essential resource. (b) Establish a framework to meet the state targets for urban water conservation identified in this part and called for by the Governor. (c) Measure increased efficiency of urban water use on a per capita basis. (d) Establish a method or methods for urban retail water suppliers to determine targets for achieving increased water use efficiency by the year 2020,in accordance with the Governor's goal of a 20-percent reduction. (e) Establish consistent water use efficiency planning and implementation standards for urban water suppliers and agricultural water suppliers. (f) Promote urban water conservation standards that are consistent with the California Urban Water Conservation Council's adopted best management practices and the requirements for demand management in Section 10631. (g) Establish standards that recognize and provide credit to water suppliers that made substantial capital investments in urban water conservation since the drought of the early 1990s. (h) Recognize and account for the investment of urban retail water suppliers in providing recycled water for beneficial uses. (i) Require implementation of specified efficient water management practices for agricultural water suppliers. 0) Support the economic productivity of California's agricultural, commercial,and industrial sectors. (k) Advance regional water resources management. 10608.8. (a) (1) Water use efficiency measures adopted and implemented pursuant to this part or Part 2.8 (commencing with Section 10800)are water conservation measures subject to the protections provided under Section 1011. (2) Because an urban agency is not required to meet its urban water use target until 2020 pursuant to subdivision(b)of Section 10608.24,an urban retail water supplier's failure to meet those targets shall not establish a violation of law for purposes of any state administrativc or judicial proceeding prior to January 1, 2021. Nothing in this paragraph 'limits the use of data reported to the department or the board in litigation or an 93 Item 16. - 162 1113 .4 Ch.4 —4— administrative proceeding. This paragraph shall become inoperative on January 1,2021. (3) To the extent feasible,the department and the board shall provide for the use of water conservation reports required under this part to meet the requirements of Section 1011 for water conservation reporting. (b) This part does not limit or otherwise affect the application of Chapter 3.5(commencing with Section 11340),Chapter 4(commencing with Section 11370), Chapter 4.5 (commencing with Section 11400), and Chapter 5 (commencing with Section 11500)of Part 1 of Division 3 of Title 2 of the Government Code. (c) This part does not require a reduction in the total water used in the agricultural or urban sectors,because other factors,including,but not limited to,changes in agricultural economics or population growth may have greater effects on water use.This part does not limit the economic productivity of California's agricultural,commercial,or industrial sectors. (d) The requirements of this part do not apply to an agricultural water supplier that is a party to the Quantification Settlement Agreement, as defined in subdivision (a) of Section 1 of Chapter 617 of the Statutes of 2002, during the period within which the Quantification Settlement Agreement remains in effect. After the expiration of the Quantification Settlement Agreement,to the extent conservation water projects implemented as part of the Quantification Settlement Agreement remain in effect, the conserved water created as part of those projects shall be credited against the obligations of the agricultural water supplier pursuant to this part.

A water supplier who met at least 10 percent of its 2008 measured retail water demand through recycled water may use a 15-year baseline period; otherwise a supplier must use a 10-year baseline. The City of Huntington Beach met 0.6 percent of its total' 2008 water demand through recycled water (indirect reuse through GWRS credit) and, as a result,must use a 10-year baseline. Table 1 shows the water from the City's own sources, imported, recycled and agricultural water use within the City water service area as well as the gross water use for purposes of determining the per capita consumption., The table also includes population of the water service area and per capita water use from fiscal years (FY) 1996 through FY 2010. Population data used herein is from the Center for Demographic Research at California State University Fullerton as obtained from the Municipal Water District of Orange County (MWDOC) and includes the entire water service area (City of Huntington Beach plus Sunset Beach). Since water use has been trending downward recently even with increasing population, per capita use has been dropping. The most advantageous period for the City to use is the one generating the highest per capita use, making subsequent conservation easier to achieve. Therefore, the 10-year period from FY 1996 thru FY 2005 was determined to be the most advantageous and was used to calculate a baseline per capita -<,:ater us,: average of 1592, GPCD as shown in Table 1. i i13 -5 39- Item 16. - 209 Ken Dills Page 2 of 4 March 29,2011 2HUN01 1401 Table I City of Huntington Beach Base Daily Per Capita Use .sWatea' ......

A water supplier must set a 2020 water use target and a 2015 interim target using one of the following four methods as defined further in Section 10608.20 of Senate Bill No. 7 (SB7x7): • Method 1: Eighty percent of the water supplier's baseline per capita water use • Method 2: Per capita daily water use estimated using the sum of performance standards applied to indoor residential use; landscape area water use; and commercial, industrial, and institutional uses • Method 3: Ninety-five percent of the applicable state hydrologic region target as stated in the State's April 30, 2009, draft 20x2020 Water Conservations Plan • Method 4: A BMP Option based on standards that are consistent with the California Urban Water Conservation Council's (CUWCC)best management practices (BMPs). PSOMAS 2 Item 16. - 210 1113 -540- Ken Dills Page 3 of 4 March 29,2011 2HUN011401 Calculation of Minimum Targets If the average base daily per capita water use is greater than 100 GPCD for a defined 5-year baseline period, the legislation's minimum water use reduction requirement must also be met as set in Section 10608.22 of Senate Bill No. 7 SB7x7. Per SB7x7, the minimum water use reduction baseline period must end no earlier than December 31, 2007 and no later than December 31, 2010 and the minimum reduction shall be no less than 5 percent of this 5-year base daily per capita water use. A minimum water use reduction baseline period between FY 2004 through 2008 was selected to calculate the most advantageous 5-year minimum water use reduction target. As shown in Table 1, the minimum baseline water use averages 144.6 GPCD. The minimum per capita water use target for 2020 must therefore be 137.4 GPCD(95%of 144.6). Calculation of Targets Using Methods 1 —4 Method 1: Using a baseline per capita average of 159.3 GPCD (shown in Table 1) the City of Huntington Beach 2020 target would be 127.4 GPCD (80% of 159.3). Since the target water use for Method 1 is less than the one found using the legislation's minimum requirement criteria (137.4), no further adjustments to this water use target would be required, if this method is selected. Method 2: The City of Huntington Beach does not currently maintain records of lot size, irrigated landscaped area for each parcel, reference evapotranspiration for each parcel, etc. to split its residential, commercial, industrial, or institutional uses into inside and outside (landscape irrigation)uses. The use of Method 2 to calculate conservation targets is therefore not feasible. Method 3: The City of Huntington Beach falls within the South Coast Hydrologic Region (Hydrologic Region 4). According to the State's April 30, 2009 draft 20x2020 Water Conservation Plan, the 2020 Target for Hydrologic Region 4 is 149 GPCD. Using Method 3, the City of Huntington Beach's 2020 water use target would be 141.6 GPCD (95%of 149). Since the target water use generated by Method 3 is greater the one found using the minimum requirement, the water target level needs to be reduced to the minimum target of 137.4 GPCD for 2020, if this method is selected. Method 4: DWR recently released this method and a calculator for agencies wishing to use this BMP-based method. A default indoor residential water savings of 15 GPCD was assumed and the City of Huntington Beach's 2005 Urban Water Management Plan was referenced to obtain the Commercial, Industrial and Institutional (CII) water use consumption (6,019 AF). Using the midpoint of the baseline period (year 2000) and DWR's "SBX7-7 Provisional Method 4 Target Calculator'resulted in a 2020 water use target of 128.3 GPCD. PSOMAS 3 11B -541- Item 16. - 211 Ken Dills Page 4 of 4 March 29,2011 2HUN011401 Conclusion The discussion and calculations above are summarized in Table 2. Table 2 City of Huntington Beach Water Use Target Summary(GPCD) LetEao 2p2U 1 127.4 2 Not Applicable 3 137.4 4 128.3 As shown in Table 2, Method 3 results in the most favorable water use target level for the City of Huntington Beach, with the minimum 5-year water use reduction governing. The 2015 interim target would then be 148.4 GPCD (mid-point between baseline of 159.3 and 2020 target of 137.4). It should be noted that the City has met this 2020 target the past two years and the 2015 target the last six years. However, FY 2010 was a water allocation year and 2009 was well publicized to water customers in Southern California as a drought condition. Therefore, demands for these two years should not be considered normal. if gross water use returns to the average of the three years prior to the past two (FY 2006-2008) of 28.7 million gallons per day (32,121 AFY), which could be assumed to be a normal year demand, using the current water service area population of 204,831, the per capita use calculates to 140.0 gallons. Therefore, there would still be some additional conservation, new direct recycled water use, or expanded GWRS use needed to reach the 2020 target, assuming existing population and normal year demands. 4 Item 16. - 212 1113 -542- City of Huntington Beach Water Demand Projections "'o, 2010 _90 2 203 ',,6 0,30�K,,L OCP.DEVELOPMENT(excl uding,B;- V NOWIntown SPs) . .......

(3854-2/10) (8) For calculation of the MAWA, the ET Adjustment Factor(ETAF) for Special Landscape Areas shall be set at 1.0. For calculation of the EAWU,the ETAF for Special Landscape Areas shall be calculated as the SLA Plant Factor divided by the SLA Irrigation Efficiency Factor. (3854-2/10) (9) Irrigation Efficiency shall be calculated using the worksheet and equation presented in Appendix B. (3854-2/10) (d) The Maximum Applied Water Allowance. (3183-2/93,3854-2/10) (1) A project's Maximum Applied Water Allowance shall be calculated using the following formula: (3183-2/93,3854-2/10) MAWA = (ETo) (0.7) (LA) (0.62)where: MAWA= Maximum Applied Water Allowance (gallons per year) ETo= Reference Evapotranspiration(inches per year) (43 inches per year in Huntington Beach) 0.7 = ET adjustment factor LA= Landscaped Area(square feet) 0.62 = Conversion factor(to gallons per square foot) (3183-2/93,3854-2/10) (2) An example for calculations of the Maximum Applied Water Allowance is: (3183-2/93,3854-2/10) Project Landscaped area of 50,000 sq. ft. in Huntington Site: Beach. MAWA= (ETo) (0.7) (LA) (0.62) (43-inches)(0.7) (50,000 sq.,ft.) (0.62) (3183-2193,3854-2/10) Maximum Applied Water Allowance (for this example)= 1,333,000 gallons per year(or 1,758 hundred-cubic-feet per year: 1,333,000 divided by 748 = 1758.6). (3183-2193,3854-2/10) (3) It is conceivable that landscaped areas in public and private projects, including but not limited to, parks, playgrounds, sports fields, golf courses, cemeteries, or school yards where turf provides a playing surface or serves other recreational or approved passive purposes may require water in addition to the Maximum Applied Water Allowance. (Those Special Landscape Areas shall have had the MAWA calculated utilizing an ET Adjustment Factor of 1.0). If this is the case, a statement shall be included with the landscape design plan, designating areas to be used for such purposes and specifying any needed amount of additional water Huntington Beach Municipal Code Chapter 14.52 Page 14 of 36 2/18/10 IIB -629- Item 16. - 299 above the Maximum Applied Water Allowance.
