I 02-101 Nov 18 Lucas(Water Quality Element) 11/7/2002 2:04 PM REQUEST FOR ACTION MEETING DATE: November 18, 2002 DEPARTMENT ID NUMBER: PW 02-101 Analysis: In March 2000, State Proposition 13 was approved to support safe drinking water quality, flood protection and water reliability projects throughout the State. Under this program, four million dollars was appropriated to the City of Huntington Beach to support projects that will address non-point sources of pollution. In December 2001, the City Council approved a contract with Camp, Dresser & McKee (CDM) to develop a CURMP, including a Water Quality Element and a Drainage Element. Development of the plan was funded under the Proposition 13 grant and includes the use of GIS (Geographic Information System) and GPS (Global Positioning System). Once complete, the CURMP will improve the City's ability to manage and track the quantity and quality of both non-storm water and stormwater discharges in the City's drainage system. The first component of the Plan, the Water Quality Element Framework, is complete and was forwarded to the City Council under separate cover. The framework will be further developed to incorporate drainage and flood study elements, monitoring and sampling data and refinement of related ordinances and standards for the CURMP. Water Quality Element The Water Quality Element will provide the basis for a comprehensive program for improving water quality through a combination of methods to reduce the volume of urban runoff and pollutants emanating from private and public property. Implementing the element will strengthen the City's efforts to meet or exceed the requirements of the City's National Pollutant Discharge Elimination System (NPDES) Municipal Stormwater Permit. The Water Quality Element is designed to provide a close look at the City and identify areas of concern based on waterway-related infrastructure and on-going monitoring. The element will help evaluate and characterize pollutants found in dry weather urban runoff through a monitoring program. Once the pollutants are identified, remedial actions and projects will be evaluated and prioritized. Drainage Element Developing a revised Drainage Element alongside the Water Quality Element provides an opportunity to efficiently integrate the quality and quantity recommendations. The Drainage Element will develop a detailed inventory of existing stormwater drainage infrastructure, compute the hydraulic capacities, document deficiencies and recommend system improvements. Recommended system improvements can address both a quality and quantity concern. For example, if it is found that a storage capacity deficit exists in an area also found to have high bacteria levels, a detention basin can be designed to include a natural cleansing feature. Citywide Urban Runoff Management Plan The CURMP will include a more detailed Water Quality Element that will further identify opportunities for integrated solutions with the Drainage Element. Collectively, these elements will provide the City with a comprehensive CURMP to enhance current efforts to 02-101 Nov 18 Lucas(Water Quality Element).doc -3- 11/7/2002 5:08 PM REQUEST FOR ACTION MEETING DATE: November 18, 2002 DEPARTMENT ID NUMBER:PW 02-101 reduce polluted urban runoff in coastal waters and reduce flooding conditions within the City. Focus Group The 2002 Water Quality Element was developed through the cooperative efforts of City staff led by the Public Works Department, CDM and a Focus Group that consisted of representatives from the City Council, community and business leaders, and environmental interest groups. The Focus Group provides an opportunity to develop a balanced program, solicit diversified input and develop a consensus of support to ensure that the City's plans are accepted and successfully implemented. The first Focus Group meeting was held on February 20, 2002, with five subsequent, full-team meetings and four subsequent sub-committee meetings. The Focus Group members include: City Council Water Quality Sub-Committee Debbie Cook, Mayor Ralph Bauer Shirley Dettloff City Staff David Webb, City Engineer Mary Beth Broeren, Principal Planner Geraldine Lucas, Environmental Engineer Community Representatives Garry Brown, Orange County Coastkeeper Richard Harlow, Chamber of Commerce Victor Leipzig, Orange Coast Watch George Mason, Public Works Commission The 2002 Water Quality Element Framework will be used as the guidance document to direct the actions of staff into next year. To maintain the aggressive schedule outlined in this report, staff expects that, with the exception of council members Dettloff and Bauer, the Focus Group membership will remain intact for further development of the Plan components, and that the Mayor will appoint two new council members to the Water Quality council Sub-committee next year. Council members Dettloff and Bauer will be invited to continue participating on the Focus Group as community members. Attachment(s): City Clerk's . - Number No. Description 1.

O �} • Section 1 Plan Overview 1.1 Plan Development and Objectives The City of Huntington Beach,California owns,operates, and maintains a storm drainage system for the purpose of conveying storm runoff so as to reduce or eliminate flooding under peak storm flow conditions.The storm drainage system begins with the streets and roads, and includes inlets,storm drains,open channels, pump stations, detention basins,and other appurtenances. While the primary purpose of the storm drain system is to reduce or eliminate flood hazards,the system carries both dry and wet weather urban runoff and the pollutants associated with runoff from urban land use and activities. Over the past few years,the general public and the City Council and staff have become much more aware of environmental concerns and the importance of receiving water quality and the potential impacts from urban runoff within the City of Huntington Beach. Because clean water is essential to support human and aquatic life,and recreation and tourism are major elements of the fabric and economy of the City, impairments to the local coastal waters have a major detrimental impact on the City. At the same time,regulatory requirements are increasingly focusing on non- point source pollution impacts from a wide variety of pollutants, particularly in urban runoff from developed areas discharged from municipal storm drainage systems and industrial and construction sites. Recognizing the importance of managing both the quantity and quality of runoff conveyed by the storm drain system,the City of Huntington Beach is undertaking an integrated City-wide Urban Runoff Management Plan(CURMP). This initial document provides a framework for the Water Quality Element of the CURMP. The Water Quality Element provides a basis for implementing a comprehensive program for improving water quality through a combination of methods to reduce the level of urban runoff and pollutants emanating from private as well as public property and thus enhancing the quality of water discharged from the municipal storm drain system within the City. Implementation of the Water Quality Element will continue to strengthen efforts by the City to meet or exceed the requirements of the City's municipal stormwater permit and the related Orange County Drainage Area Management Plan(DAMP),anticipate other future regulatory requirements,and address water quality and other related environmental goals of the City and its residents,businesses,staff and City Council. The CURMP will include this Water Quality Element and a Drainage Element to take advantage of information developed under both efforts and identify integrated solutions that address both water quality and flood hazard protection goals. Figure 1-1 illustrates how the CURMP is comprised of the Water Quality Element and Drainage Element. cm 1-1 P110690-Munbngton BeacM34680-WOMP-MPD\7PR0JD0D\6 Task6\Master Plan\Sections\Section 1.dX Section 1 City of Huntington Beach 2002 Water Quality Element Drainage Element F City-Wide Urban Runoff Management Plan k City of Huntington Beach Water Quality Element it Figure 1-1 City-Wide Urban Runoff Management Plan Cm 1-2 P110690-Hen6nglon 6eaW34680-WOMP-MPDV PROJDOO\6.Task6\Master Plan\Smbons\Se lion 1.dm Section 1 City of Huntington Beach 2002 Water Quality Element Figure 1-2 illustrates how the Water Quality Element provides the basis for implementing a comprehensive program described in this document.

The Focus Group members included: City Council Debbie Cook, Mayor Ralph Bauer Shirley Dettloff Ci Staff Mary Beth Broeren,Principal Planner Geraldine Lucas,Environmental Engineer David Webb,City Engineer Cm 1-3 P\10690-Huntington Beach\34680-WOMP-MPD\7PROJDOC\6.Task6\M3ster Plan\Swfions\Sec6on 1 Aoc Section 1 City of Huntington Beach 2002 Water Quality Element Community Members Garry Brown,Orange County Coastkeeper Richard Harlow,Chamber of Commerce and Development Community Victor Leipzig,Orange Coast Watch George Mason,Public Works Commission and Southeast Huntington Beach Neighborhood Association Through the efforts of the Focus Group and Study Team, the following objectives were developed for the Water Quality Element. The Water Quality Element will guide the City's urban runoff program to improve the quality of local coastal waters, harbours, lakes and other urban waterways in order to: ■ Protect public health and safety; ■ Protect and enhance the beneficial uses such as recreation, aesthetics, economics, and habitat value of the local aquatic systems; ■ Reduce pollutants and urban runoff flows; ■ Comply with state and federal regulations; ■ Increase public awareness and education, ■ Integrate water quality and drainage planning activities; ■ Efficiently use resources within the City,and ■ Achieve improved regional approaches. The framework Water Quality Element described in this document was formulated to address these objectives. While the CURMP provides a basis for managing the runoff generated from within the City of Huntington Beach,it is also important to recognize that full protection and enhancement of the water bodies requires a comprehensive regional effort on the part of numerous other public entities, private interests, and regulatory agencies. Urban runoff in the major urban waterways and coastal waters in Huntington Beach originates from many other upstream jurisdictions. Furthermore,pollutant discharges and receiving water impacts can result from sources other than urban runoff. Therefore,adoption and implementation of a CURMP provides the City with a basis for proactive participation in regional solutions.

Therefore,the Water Quality Element establishes a Program Framework that includes a broad combination of approaches to reduce the level of urban runoff and pollutants and enhance the quality of water discharged from the municipal storm drain system within the City. These approaches have been organized in three distinct major program components: ■ City-Wide Source Control Programs ■ Program for New Development/Significant Redevelopment ■ Watershed Planning Area-based Programs and Projects A brief summary of each of these three components are illustrated below in Figure 1-3 including a summary of the key elements,the participants or affected parties, and the types of"tools' needed to implement the elements.

Pollutant sources can originate from virtually all existing land uses and activities within the City and these programs generally are applicable city-wide. In some cases, as noted in Section 1.2.3,source control programs may include focused or customized elements applicable to certain planning areas. Many of the source control programs are existing core elements of the City's National Pollutant Discharge Elimination System (NPDES) stormwater permit compliance program and are already being effectively implemented. These source control programs will be included in the complete Water Quality Element. Program areas include: ■ Legal Authority/ Enforcement ■ Public Agency Activities including: — Litter Control — Solid Waste Collection/Recycling — Drainage Facility Maintenance — Catch Basin Stenciling — Street Sweeping — Household Hazardous Waste Collection(coordinate with County program) — Emergency Spill Response — Fertilizer and Pesticide Management — Fixed Facility Inspections ■ Public Education/Outreach ■ Construction Site Water Quality Inspections ■ Industrial/Commercial Water Quality Facilities Inspections ■ Illegal Discharge and Illicit Connection Elimination ■ Sewer System Operation and Maintenance Cm 1-6 PA10690-Huntington Beacht34680-WOMP-MPDVPROJD006.TasMMaster PlankSections\Section 1.dw Section 1 City of Huntington Beach 2002 Water Quality Element The combination of these source control programs requires actions and/or are effectively implemented by almost every segment of the City including residents, tourists,businesses,contractors and staff from many different City Departments. Implementation"tools" for conducting source control programs include staff time, equipment,operation and maintenance budget,ordinance adoptions and enforcement,and education and training. 1.2.2 Program for New Development/Redevelopment New development and redevelopment of property and changes of land use within the City present unique challenges and opportunities relative to urban runoff quality management. Development or redevelopment of a property typically creates or adds impervious surface area,which results in increased runoff and increased pollutant load. Development also creates an opportunity to incorporate design features into a project based on current stormwater management principles to fully mitigate the increased runoff and water quality impact of development of that property. This can be done at relatively low incremental cost compared to potentially much higher costs to construct or retrofit facilities to mange runoff from existing developed areas. Furthermore,management of new development/redevelopment is another core element of the City's NPDES compliance program. The component applies to both private development projects and equivalent City capital improvement projects. Implementation of this program component is primarily the responsibility of property owners/developers and the City staff that oversee the planning and construction permit programs, as well as City Departments that undertake major new capital projects. Successful execution of the program requires tools that include general plan policies and CEQA review guidelines, development standards, permit requirements and enforcement,and incremental project cost additions borne by developers or City capital programs. In addition,certain stormwater measures that would be constructed with new projects will have long-term operation and maintenance requirements. 1.2.3 Watershed Planning Area-Based Programs and Projects This category includes structural measures or localized source control programs that are targeted in one particular drainage area that will reduce runoff and/or provide enhanced water quality benefits beyond what can be achieved through implementation of the typical City-wide measures implemented to meet NPDES permit requirements. Many of these are"opportunistic" projects that take advantage of available land or natural features, potentially serve dual benefits,or have already been identified and are under study as possible programs. cm 1-7 P110690-Huntington Be M34680-W OMP-MPD\7PROJDOC\6.Task6\Master P1aMSections\Sm6on 1.dm Section 1 City of Huntington Beach 2002 Water Quality Element City staff will generally implement watershed programs and projects, although some may be more appropriately implemented as a regional program jointly with the County of Orange and/or other upstream cities. Specific projects or programs will typically require capital and/or operation and maintenance funding with potential for grant and loan funding,City staff time for implementation, and significant land for construction that would be either City- owned land or be acquired from private ownership. 1.2.4 Monitoring and Feedback The Water Quality Element includes a plan to provide monitoring and feedback that can be used to periodically review and update this plan. Monitoring can take a number of forms from actual field water quality monitoring to gathering and assessing program performance data so as to verify planning assumptions with actual observations. 1.2.5 Document Contents This Water Quality Element includes the following sections: ■ Section 1 provides an overview of the Water Quality Element framework. ■ Section 2 presents a brief background summary of urban runoff characteristics,the existing drainage system and watershed setting,runoff quantity and quality, and the water quality regulatory framework. ■ Section 3 contains a detailed description of all potential elements of the plan. ■ Section 4 provides recommendations with respect to program and project priorities. ■ Section 5 presents a schedule for implementation of the Water Quality Element, discussion on potential funding sources,policy and ordinance development,and a plan for monitoring and feedback on plan implementation. Cm 1-8 P110690-Huntington Beach\34680-WOMP-MPD\7PROJD006.Task6\Master Plan\Se(ions\Section 1.dx Section 2 � o 0 v Section 2 Background As urban runoff(both dry and wet weather) discharges into the urban waterways, lakes,bays,and the ocean,it can be a source of contamination. Prior to the development and adoption of this Water Quality Element,the City of Huntington Beach has already taken many proactive steps for controlling runoff quality. Examples of such steps include: ■ Initiating an interim dry weather runoff diversion program in both the Santa Ana River and Talbert/Huntington Beach channel areas to minimize any impact of dry weather runoff on coastal water quality. ■ Requiring source and treatment control BMPs to be incorporated in new development and redevelopment projects. ■ Implementing a number of source control measures and public education programs that meet or exceed requirements of the NPDES stormwater permit. ■ Seeking and receiving grant funding for water quality control programs including conducting this CURMP,installing treatment systems at a number of storm drain outfalls,and drainage system maintenance and cleaning. Extensive studies have indicated that sources such as leaking sewers are not a contributor to recent high bacterial counts in coastal waters. Additional studies conducted by the City and others are continuing to identify sources and work toward the specific objective of minimizing posting and closure of coastal waters. The Citywide Urban Runoff Management Plan(CURMP)will provide a broad framework for managing the quantity and quality of all urban runoff that reaches receiving waters from the land surfaces and through the storm drain system within the City. This Water Quality Element framework document initially focuses primarily on managing runoff quality. As drainage studies are completed,the CURMP will address water quality flood hazard and potential common solutions that can address both water quality and quantity concerns. 2.1 Urban Runoff Overview The term urban runoff as used in this Plan is defined as all flows in the storm drain system under both dry and wet weather conditions. In this context, the drainage system includes yard drains, swales,streets,curbs and gutters,storm drain inlets and catch basins,underground pipes, pump stations,open channels,lakes, detention basins,storm drain outfalls, and other designated water quality features such as vegetated swales,ravines,vegetated filter areas and wetlands. For management purposes,urban runoff has been divided into three categories summarized as follows: Cm 2-1 PA10690-Huntington Beach\34680-W OMP-MPD\7PROJDOC\6.Task6\Master PIWSecfions\Section 2.dx Section 2 City of Huntington Beach 2002 Water Quality Element ■ Dry weather urban runoff occurs throughout the year when there is no precipitation-generated runoff. Typical sources include landscape irrigation runoff; driveway and sidewalk washing; groundwater seepage;fire flow;potable water line operations and maintenance discharges;and permitted or illegal non- storm water discharges. Dry weather runoff is principally a water quality concern. It can be a significant source of bacteria and other constituents that can be introduced through day-to-day urban activities as well as illicit discharges, dumping,or spills. Flow quantities can represent a substantial year-round volume of water discharged with associated pollutants. Furthermore,dry weather runoff quantity is an important factor that influences the ability to implement control measures such as diversion to the sanitary sewer,treatment and discharge,or reuse. Dry weather flow quantities are estimated from monitoring data and cannot be predicted using normal hydrologic projections. Drainage system capacity and condition are typically not a concern for conveying dry weather flows. ■ Small storm runoff is typically the source of a high percentage of both overall wet weather runoff volume and pollutant loads on an average annual basis. Typical design storm events used as targets for water quality management strategies are typically less than the volume generated from a one-year frequency storm event, or 10% of the peak flow rate of a 50-year peak storm event. Water quality design storms are not those that produce significant flooding potential or cause drainage system capacity deficiencies. However, planning and design of any water quality measures or Best Management Practices (BMPs) should effectively target the removal of pollutants during the more frequent small storm events as well as safely convey the peak flows. ■ Large storm peak runoff is of greatest concern for drainage system capacity analysis. It is not typically considered in water quality management except where natural or unlined channels have the potential for erosion under peak flows or increasing flows resulting from development;or where flood flows can cause the release of pollutants into the drainage system such as from surcharging sanitary sewer facilities. 2.2 Existing Drainage System The City of Huntington Beach is located adjacent to the Pacific Ocean within a heavily urbanized region of Orange County,California. Bordering cities include Seal Beach, Westminster,Fountain Valley,and Costa Mesa. Storm water discharges from the urbanized areas in Orange County consist mainly of surface runoff from residential, commercial,and industrial developments. In addition,there are storm water discharges from agricultural land uses,including farming and animal operations. Discharges from various areas within the City drain directly or indirectly into urban streams,city lakes,bays,wetlands,estuaries,and the Pacific Ocean.

The drainage area within the Lower Santa Ana River Basin and Orange County contains approximately 2.8 million residents,occupying an area of approximately 786 square miles (including unincorporated areas and the limits of 33 cities,25 of which are within the RWQCB's jurisdiction). The City resides within the following three regional watersheds as designated by the Orange County Public Facilities and Resource Department Watershed and Coastal Resources Division and shown in Figure 2-1: ■ Lower Santa Ana River Watershed ■ Talbert/Greenville Banning Channel Watershed ■ Westminster Watershed ] , S ' Stanto r Anaheim Lo lamto r s � r - _ Garden rove Seal Wesiminster , �� Santa - `1 Ana t� Huntington , ' Fountain ••� Beach Valley Legend Costa — City Boundary Mesa Regional Watershed Boundary C C: Westminster j D: TalbertlGreenville Banning Channel E: Lower Santa Ana River I� Figure 2-1 Regional Watershed Map Cm 2-3 P:\10690-Hunfing\on Beach\34680-W DMP-MPD\7PROJDOC\6.Task6\Master Poan\Sections\Section 2.do Section 2 City of Huntington Beach 2002 Water Quality Element A small portion(slightly over one square mile) of the City drains directly to the Santa Ana River. The river begins approximately 75 miles away in the San Bernardino Mountains before crossing Orange County then ultimately emptying into the Pacific Ocean adjacent to the City as shown in Figure 2-2. By contrast,the overall Santa Ana River watershed collects surface flows from approximately 1,675 square miles and can therefore have substantial influence on the local coastal waters. The Orange County portion of the Santa Ana River watershed includes portions of other cities such as Anaheim, Brea,Orange,Placentia,Santa Ana,Villa Park,and Yorba Linda. Santa Ana, Rer .r W ateshe V c {a Huntington Beach Figure 2-2 Santa Ana River Watershed The Talbert/Greenville Banning Channel Watershed covers 21.4 square miles and straddles the mouth of the Santa Ana River. Two main tributaries drain this watershed. On the western side,the Talbert Channel and Huntington Beach Channel drain through the Talbert Marsh prior to emptying into the Pacific Ocean.

The East Garden Grove-Wintersburg Channel drains past the Bolsa Chica Wetlands and then into Huntington Harbour. Topography within the City ranges from just below sea level to almost over 100 feet mean sea level with surface water flows ultimately discharging to the Pacific Ocean. The most prominent topographical features within the City are the Huntington and Bolsa Chica Mesas. The Bolsa Chica Mesa is located near the coast at the western end of the City,north of the Wintersburg Channel and south and east of Huntington Harbour. The maximum elevation of the Bolsa Chica Mesa is approximately 65 feet mean sea level. Elevations on the Huntington Mesa exceed 100 feet mean sea level. The regions surrounding the mesas within the City have surface elevations ranging from below sea level to over 25 feet mean sea level. Drainage from within the City is conveyed through streets,curbs,and gutters to a City storm drain system consisting of underground pipes,pump stations,and open channels as well as several Orange County channels. For water quality planning purposes, drainage areas within the City have been consolidated into planning areas as shown in Figure 2-3. The planning area names are based on the water body or other surface features to which they discharge. The planning watersheds as they are defined for this Water Quality Elements and their drainage areas are presented in Table 2-1. An overview of each planning area is presented below: ■ Santa Ana River Planning Area-Approximately 1.2 square miles of Huntington Beach drains to the River. Surface flows observed in the Santa Ana River are intermittent or are the result of storm water runoff immediately following a precipitation event or dry weather discharges. Most base flow in the river is captured for recharge well upstream of the City. Two storm water pump stations collect surface flows from within the City and discharge the water to the River. Currently,all dry weather flow within this area is diverted at the pump stations to the sanitary sewer system. Predominant land use in this planning area is single family residential with some multi-family residential and commercial areas as well. cm 2-5 R00690-HunBngton Beach\34680-WOMP-MPD\7PROJD006.Task6\Master Plan\Sections\Section 2Aoc Section 2 City of Huntington Beach 2002 Water Quality Element Table 2-1 City of Huntington Beach Water Quality Planning Areas Approximate Water Quality Drainage Area Planning Areas Miles s Dischar a Point Regional Watershed Santa Ana River 1.2 Santa Ana River Santa Ana River Talbert Channel 7.3 Talbert Marsh Lower Santa Ana River Coastal 1.2 Huntington City Beach Bolsa Chica Wetlands 1.5 Bolsa Chica Wetlands Westminster Slater Channel 3.9 Huntington Harbour Westminster Wintersburg Channel 5.3 Huntington Harbour Westminster Harbour 3.0 Huntington Harbour Westminster Bolsa Chica Channel 2.5 Mouth of Harbour,Anaheim Westminster Total 25.9 Bay ■ Talbert Channel Planning Area-The Talbert Marsh is a wetland roughly paralleling the inland side of Pacific Cost Highway. The marsh receives surface flows from the Huntington Beach Channel and the Talbert Channel. Flow from the adjacent city of Fountain Valley contributes to Talbert Channel through the Fountain Valley Channel,which is a tributary to the Talbert z Channel. This watershed contains eight pump storm water stations (7 City-operated/1 LA County-operated) that collects the runoff and conveys it into the two channels. Currently, all dry weather flow collected at the seven City pump stations is diverted to the sanitary sewer system. The predominant land uses in this planning area are single-family residential, commercial business,and multi-family residential. ■ Coastal Planning Area-This planning area is entirely within the City and does not contain any City or county channels. The area consists of i Y" several smaller storm drains that discharge onto _ t" the beach with wet weather runoff flowing to the Pacific Ocean. Predominant land use in this planning area is multi-family residential and r commercial businesses.

The area consists of local storm drains from the Seacliff area and one pump station that discharges through a natural channel __ -_ and a fresh water pond system to the Bolsa Chica Wetlands. Land use in this planning area is predominantly newer single family residential developments with some older single and multi- family residential areas. ■ Slater Channel Planning Area- This planning area lies wholly within the City and does not receive flow from other jurisdictions. A large portion of surface runoff within this planning watershed flows through Talbert and . . - Huntington Talbert Lakes or to Sully-Miller Lake. Huntington Lake and Sully-Miller Lake typically hold water throughout the year while Talbert Lake generally does not. This Central Park lake system is an integral part of the City's drainage infrastructure acting as retention. The lakes are also significant from a water quality standpoint as Talbert and Huntington Lakes act as terminal lakes (no surface water exit) under small to moderate storm events and Sully-Miller Lake has no discharge except through groundwater recharge. During moderate to large storm events,stormwater discharges from Huntington Lake into Slater Channel. At the Slater pump station, the discharges are then pumped into Wintersburg Channel. The predominant land uses within this planning area include a mixture of single and multi-family residential, parks,commercial, and industrial areas. cap 2-7 PA10690-Huntington Beach\34680-W OMP-MPD\7PROJDOC\6.Task6\Master Plan\Sections\Section 2.00c City of Huntington Beach ` OTT OF HSHSI=ff" Planning Areas and Drainage Facilities PLWW VAX=„AR11@" ANAHEIM BARBER CITY CHANNEL BOLSA CHICA CHANNEL f WESTMINSTER CHANNEL a cur NOT TO SCALE ES TER � ANAHEIM BAY I I EAST GARDEN CHANNEL ROVE CHANNEL 1 ' � OCEAN VIEW CHANNEL \ B L rioa i� I WIN ERSBUf� FOUNTAIN VALLEY CHANNEL tJ' TALBERT SANTA ANA _ CHANNEL RIVE Y �r • L I T 1 If i L iJ CK J.

East Garden Grove �= Channel collects upstream flow from the cities of Westminster, Jill Santa Ana,Garden Grove, Orange,and Anaheim. The Ocean View Channel collects upstream flow from the city of Fountain Valley. Within the City itself,these channels join to form the Wintersburg Channel. Further downstream,Slater Channel enters into Wintersburg Channel. The Wintersburg Channel then discharges into the Outer Bolsa Bay and then into Huntington Harbour,Anaheim Bay and the Pacific Ocean. Surface waters in the Outer Bolsa Bay,Huntington Harbour and Anaheim Bays are all under tidal influence. The predominant land uses for this planning area are a mixture of single and multi-family residential,commercial,and industrial areas. ■ Huntington Harbour Planning Area- The Huntington Harbour planning area includes surface flows discharged from within the City via a network of smaller storm drains within the areas immediately adjacent to the Harbour and from a relatively small area to its east. Predominant land use areas within this planning area include single and multi- family residential and commercial areas. Huntington Harbour also receives substantial flows from both the Wintersburg Channel and Bolsa Chica Channel. ■ Bolsa Chica Channel Planning Area- Surface flows from the northwestern portion of the City discharge to the Anaheim Barber City Channel, the Bolsa Chica Channel and the Westminster Channel. These channels define the western boundary of the City and receive flow from upstream cities. The Anaheim Barber City Channel receives surface flows from the cities of CM 2-9 PA10690-Huntington Beacha4680-WOMP-MPM7PR0JD0C\6.Task6\Master Plan\Sections\Seceon 2.do Section 2 City of Huntington Beach 2002 Water Quality Element Westminster,Garden Grove,Stanton,and Anaheim and joins the Bolsa Chica Channel at Bolsa Chica Road between Bolsa Avenue and Westminster Boulevard. The Bolsa Chica Channel receives surface flows from the Seal Beach Naval Weapons Station,Westminster,Seal Beach,Garden Grove,the Armed Forces Reserve Center(Los Alamitos),Cypress,and Stanton. These combined surface flows then eventually discharge at the mouth of Huntington Harbour and to Anaheim Bay. The predominant land uses in this planning area are industrial and single family residential areas. 2.3 Runoff Quantity and Quality For runoff management planning, it is important to develop estimates of runoff quantities that need to be managed and understand the water quality of dry and wet weather runoff. Detailed estimates of runoff peak flows and volumes and pollutant load projections are being developed under the Drainage Element of the CURMP. Preliminary estimates of overall runoff volumes were derived for this Water Quality Element framework document,and general characterization of runoff quality was derived from regional water monitoring programs and a dry weather sampling program conducted during the development of this plan. 2.3.1 Runoff Quantity For the CURMP,estimates of average annual runoff volumes for both dry and wet weather runoff were developed based on monitoring data from dry weather urban runoff and average hydrology and runoff calculations for wet weather runoff. Detailed estimates of wet weather runoff peak flows for use in evaluating drainage system needs and preliminary sizing of conveyance system improvements and major water quality projects will result from the analyses conducted under the Drainage Element. To help understand and illustrate the relative quantity of annual runoff within the City, Figure 2-4 Estimated Average Annual Flows,compares the estimated annual runoff volumes (acre-feet)within the City from both wet and dry weather runoff. Using a combination of dry weather monitoring data collected from several channel sites during the development of the Water Quality Element, previous analysis by the City of dry weather pump station operating data,and data compiled from other similar jurisdictions,an average dry weather flow factor of approximately 150 gallons per day (gpd) per acre was established for planning purposes. Using this factor the annual dry weather runoff from the roughly 26 square miles of drainage area within the City is approximately 2,800 acre-feet. Based on an 11-inch average annual rainfall and typical runoff coefficients for a mixed,relatively urbanized watershed, total long term average annual wet weather runoff from the same City drainage areas is estimated to be approximately 8,000 acre- feet. This value,however,is highly variable from year to year, depending upon seasonal rainfall patterns.

Based upon historical rainfall data in Orange County and assuming a 500-acre drainage area for comparative purposes, peak instantaneous wet weather flows can be calculated for a 2-year storm,10-year,and 50-year storm. Figure 2-5 shows that there are orders of magnitude differences in flow magnitudes between wet weather and dry weather runoff. Despite the large differences in peak flow rates,dry weather runoff is still a significant concern because it is present all year long and therefore still contributes a substantial amount of total annual volume to the drainage system and receiving waters.

Based on dry weather flow monitoring and watershed areas,it is estimated that the runoff from Huntington Beach represents about 35-40% of all flow discharged to the receiving waters through these watersheds (excluding the Santa Ana River). 2.3.2 Runoff Quality There are pollutants of concern in both wet and dry weather runoff. Information on the anticipated quality of runoff from Huntington Beach and the upstream contributing areas to the local storm drain channels comes from several sources including: ■ Recent dry weather sampling from 37 locations within the City including major channels, pump stations,significant storm drain discharge points to the channels, outfall points at the beach and wetlands, and permanent lakes (Huntington and Sully-Miller). ■ Dry and wet weather sampling at three Orange County PFRD sampling stations located inside or just upstream of the City ■ Prior sampling conducted by the City at pump stations in the Talbert/Huntington Beach Channel area Cm 2-12 PA10690-Huntington Beach\34680-WOMP-MPD\7PR0JD0C\6Task6\Mas1er Plan\Se Uons\Se hon 2doc Section 2 City of Huntington Beach 2002 Water Quality Element ■ Prior bacteriological sampling by UCI in the Talbert/Huntington Beach Channel area ■ Regional stormwater monitoring data gathered by stormwater agencies throughout Southern California Principal dry weather pollutants of concern include: ■ Bacteria indicators. Indicator bacteria are found in all samples and are considered indicators of the possible presence of human pathogens. Densities vary widely, but are frequently found in dry weather runoff at levels greater than allowable for body contact. While the local storm drain system and channels are not designated as receiving waters with beneficial uses (except for the Santa Ana River), dry weather runoff can reach the various coastal waters where water quality objectives apply. ■ Pesticides and petroleum hydrocarbons. These compounds can potentially be found in dry weather runoff as a result of normal use and/or illegal dumping and discharge;however, dry weather sampling within the City found no detectable pesticide presence and minimal petroleum hydrocarbons. ■ Metals. Metals can potentially be found in dry weather runoff but typically at levels much lower than in wet weather runoff. This is observed in sampling with most metals either not detected or detected below levels of concern in most samples. Arsenic,cadmium,lead and nickel were below California Ocean Plan 6-month median water quality objective(most stringent standard)for almost all samples. Copper and zinc were found above the 6-month objective more than half the time, but below daily maximum in almost all samples. ■ Nutrients. Nitrogen and phosphorus are present in dry weather runoff but in generally lower levels. There are no Ocean Plan water quality objectives for nutrients, although inland lakes could be affected by excess nutrient loading. Total nitrogen is well below the nitrate-nitrogen standard for drinking water if groundwater recharge of dry weather runoff were to be considered. Wet weather runoff typically contains pollutants of concern similarly found in dry weather runoff and also contains other pollutants not typically found in dry weather runoff. However, the concentrations levels are typically higher than levels found in dry weather flows because the larger wet weather flows dislodge or carry pollutants over different surfaces that lower dry weather flows are not able to transport. These pollutants of concern include: ■ Bacterial indicators. The bacterial densities are typically 1 to 2 orders of magnitude greater than in dry weather runoff.

Significant loads of trash, debris, and coarse solids can be found in wet weather urban runoff. Vegetation can be a substantial component of coarse solids. ■ Suspended solids. This includes coarser to very fine sediments resulting from soil erosion and many other natural and human-activity based sources of sediment. ■ Metals. Concentrations of certain metals frequently detected in urban runoff(e.g. Copper, Lead and Zinc)can be five to ten times greater in wet weather runoff than dry weather runoff. ■ Nutrients. Nitrogen and phosphorus concentrations can be 2 to 3 times higher in wet weather runoff compared to dry weather runoff. ■ Hydrocarbons/oil and grease. Elevated levels of oil and grease and petroleum hydrocarbons can be found in wet weather runoff,particularly from streets,roads, and other paved surfaces. 2.4 Regulatory Framework Under the Clean Water Act(CWA), the state of California was originally required to develop comprehensive drainage basin plans, as a prerequisite to receiving federal funding for the construction of municipal wastewater treatment plants. Within California,the State Water Resources Control Board (SWRCB) and its nine Regional Water Quality Control Boards (RWQCBs) are responsible for the protection of California's waters. The SWRCB sets policy statewide and the RWQCB implements the federal and state laws and regulations. The Santa Ana Regional Water Quality Control Board (SARWQCB) developed the Water Quality Control Plan(Basin Plan) for the Santa Ana Region in 1975,with subsequent updates in 1983 and 1995 and periodic amendments. The Basin Plan guides conservation and enhancement of water resources and establishes beneficial uses of inland surface waters, tidal prisms,harbours,and groundwater basins within the Santa Ana Region. The beneficial uses designated in the Basin Plan for the City's relevant receiving waters are summarized in Table 2-2 Cm 2-14 P-\10690-Huntington Beach\34680-W OMP-MPD\7PROJD006.Task6\Master Plan\Sections\Section 2.00c Section 2 City of Huntington Beach 2002 Water Quality Element Table 2-2 Beneficial Uses of Project Drainages BENEFICIAL USE Ocean Waters MUN AGR IND PROC GAR NAV POW REC1 REC2 COMM WARM LWRM COLD BIOL WILD RARE SPWN MAR SHELL EST Near shore Zone—San Gabriel River to Poppy Street in Corona Del Mar + X X X X X X X X X X Offshore Zone—Waters Between Near shore Zone and Limit of State Waters + X X X X X X X X X Bays,Estuaries and Tidal Prisms Anaheim Bay—Outer Bay + X X X X X X X I X Anaheim Bay—Seal Beach National Wildlife Refuge + I X1 X X X X X X X Sunset Bay—Huntington Harbour + X X X X X X X X Bolsa Bay + X X X X X X X X X Boise Chica Ecological Reserve + X X X X X X X X Tidal Prism of Santa Ana River(to within 1000'of Victoria Street)and Newport + X X X X X X Slough Tidal Prisms of Flood Control Channels Discharging to Coastal or Bay Waters 3 + X X X X X Inland Surface Streams Lower Santa Ana River Basin—Santa Ana River,Reach 1—Tidal Prism to 17th + X2 X Street in Santa Ana Notes: MUN=Municipal and Domestic:AGR=Agncultural Supply:IND=Industrial Service Supply:PROC=Industrial Process Supply GWR=Groundwater Recharge;NAV=Navigation;POW=Hydropower Generation;REC7=Water Contact Recreation;REC2=Non-contact Water Recreation;COMM=Commercial and Sport Fishing;WARM=Warm Freshwater Habitat;LWRM=Limited Warm Freshwater Habitat:COLD=Cold Freshwater Habitat;BIOL=Preservation of Biological Habitats of Special Significance;WILD=Wildlife Habitat;RARE=Rare.

The Basin Plan also contains an Implementation Plan that is intended to achieve the overall objectives of the Basin Plan. Two primary implementation mechanisms that affect management of urban runoff from Huntington Beach include the NPDES permit system for stormwater and the Total Maximum Daily Load process. In accordance with the CWA, an NPDES permit is required for certain municipal separate storm sewer discharges to surface waters. The City of Huntington Beach is within the region covered originally by Order No.R8-2002-0010(NPDES Permit No. CAS618030) issued by the SARWQCB on January 18,2002. The County of Orange is the principal Permittee,with Orange County Flood Control District(OCFCD) and 25 incorporated cities (Anaheim, Brea,Buena Park,Costa Mesa, Cypress,Fountain Valley,Fullerton,Garden Grove,Huntington Beach,Irvine, Laguna Woods,La Habra,La Palma,Lake Forest,Los Alamitos, Newport Beach,Orange, Placentia,Santa Ana,Seal Beach,Stanton,Tustin,Villa Park,Westminster,and Yorba Linda) within Orange County as co-Permittees. Under the permit,Permittees are required to continue implementation of the Drainage Area Management Plan(DAMP). The DAMP is the principal policy and guidance document for the countywide NPDES storm water program. The objective of the DAMP is to fulfill the commitment of the Permittees in presenting a plan satisfying the NPDES permit requirements and evaluating the impacts of urban stormwater quality on the beneficial uses. The DAMP contains requirements in seven general categories: ■ Public Agency Activities ■ Public Education ■ New Development/Significant Redevelopment ■ Construction ■ Industrial Discharger Identification ■ Detection/Elimination of Illegal Discharges and Illicit Connections ■ Water Quality Monitoring In July 1999, the SWRCB issued a new Statewide NPDES General Permit for storm water discharges associated with construction activities (General Construction Permit),in accordance with federal storm water regulations,which superseded the first General Permit issued in 1992. Developers planning construction activities as well as any city construction project disturbing an area greater than five acres are cm 2-16 PM0690-Huntington BeaW34680-WOMP-MPD\7PROJDOC\6.Task6\Master PWMSmfions\Section 2 dm Section 2 City of Huntington Beach 2002 Water Quality Element required to file a Notice of Intent(NOI) to discharge under the Construction Activity Permit. After a NOI has been submitted, the discharger is authorized by the SWRCB to discharge storm water under the terms and conditions of the General Permit in effect at the time of application. The major provisions of the General Permit are listed below. ■ Eliminate or reduce non-storm water discharges to storm sewer systems and other waters of the nation; ■ Develop and implement a Storm Water Pollution Prevention Plan(SWPPP);and ■ Perform inspections of storm water pollution prevention measures (control practices). By March of 2003,the Permit will be revised to reflect the Phase II stormwater regulations and the construction permit threshold will be reduced to one acre of disturbance. The City of Huntington Beach has been implementing local programs in accordance with the DAMP and the Municipal Permit since the issuance of the first DAMP in 1993. The City also has programs to ensure that developers agree to comply with the General Construction Permit. The City is currently reviewing and will be modifying programs to meet the updated requirements contained in the 2002 Permit. The Water Quality Element incorporates the programs required under the Permit. The relationship between federal,state,and local regulatory agencies and permits, and the City's implementation of its stormwater program is illustrated in Figure 2-6.

The purpose of the TMDL program is for states to identify streams,lakes, and coastal waters that do not meet certain water quality standards and are not expected to meet standards solely through technology-based controls of point source Cm 2-17 P:110690-H-Ungm 6eacn134680-WQMP-MPDVPR0JD0C16.7ask61MaSW PIan1SWV0ns1Sw2ion 2.do Section 2 City of Huntington Beach 2002 Water Quality Element discharges. For such watersheds,a TMDL for the constitue_Zt(s)for which the water body is impaired must be determined. The TMDL is a calculation of ti-ie:7?axirs-m amount of a pollutant that a waterhody can receive and still achieve the target-eater quality objective. All sources of the constitaent(s) must be identified and loads quantified. Load reductions are determined and then allocated among the sources. Finally,an implementation plan is prepared to achieve the load reductions. The purpose of the TMDL program is not to replace existing water po'l.ution control programs,but to provide a framework for evaluating pollution control efforts and allow for coordination between federal, state and local efforts to meet water quality standards. Anaheim Bay and Huntington Harbour are the water bodies listed on the 1998 California 303(d) list. The TMDL priority schedule for these receiving water bodies is summarized in Table 2-3. The State Water Resources Control Board has proposed an updated 303(d)List and TMDL Priority Schedule for 2002 and is expected to adopt a new list late this year. The proposed listings affecting Huntington Beach are generally similar,but include the new listing of Huntington Beach State Park for High Coliform Count and an increase in affected area for Anaheim Bay and Huntington Harbour. cm 2-18 P 110690-Hun6ngton Beach\34680-W OMP-MPDV PROJDOC\6 Task6\Master Plan\Sections\Section 2Aoc Section 2 City of Huntington Beach 2002 Water Quality Element Table 2-3 1998 California 303(d)and TMDL Priority Schedule Water Body 3 O d l0 = N to B O O TMDL rn rn 'd c c r c c m Pollutants/ Completion Date c i = m Stressor Source Priority (Fiscal Year) P High Coliform Count Unknown High 2010/11 Urban Runoff/Storm X Metals Sewers; Unknown Medium 2010/11 Non-point Source X Metals Urban Runoff/Storm Medium 2010/11 Sewers/Boat Yards X Pathogens Urban Runoff/Storm Medium 2010/11 Sewers Urban Runoff/Storm Sewers;Atmospheric Deposition; P(,) Trash Recreational and Low N/A Tourism activities (non-boating); Boat Discharges/Vessel Waste X X Pesticides Unknown Non-point Medium 2010/11 Source X=Listed on the 1998 California 303(d)List and TMDL Priority Schedule P=Proposed listing by the SURCB for 2002 California 303(d)List and TMDL Priority Schedule (1)=all Orange County beachesefestuaries c 2-19 PA10690-Huntington Beach W80-WOMP-MPDI7PR0JD006.Task6Waster PWXSmc onslSedion 2.eoc Section 3 r ' � W A', O W a m x a + - i Section 3 Plan Components The Water Quality Element of the CURMP for the City of Huntington Beach consists of both program elements and specific projects that can be implemented to meet the established water quality objectives. Through the course of development of the Water Quality Element including Focus Group input,a wide range of potentially viable programs and projects were identified to be included in the Water Quality Element for possible implementation. As noted in Section 1, the plan elements are contained in three major categories: ■ City-Wide Source Control Programs ■ Program for New Development/Redevelopment ■ Water Quality Planning Area Programs and Projects A description of the key elements under City-Wide Source Control Programs is discussed in Section 3.1. Key elements for the New Development and Redevelopment Program are discussed in Section 3.2. Descriptions of all identified water quality planning area programs and projects are provided in Section 3.3. 3.1 City Wide Source Control Programs This category includes a wide variety of activities and programs whose primary purpose is to prevent the introduction of pollutants to the storm drain system or receiving waters through control at the source. Pollutant sources can originate from virtually all land uses and activities within the City,and these programs generally are applicable Citywide. In some cases,source control programs may include focused or customized emphasis in certain planning areas. Most of the source control programs are existing core elements of the City's NPDES compliance program and are already being implemented to some degree. Additional commitments to meet new Permit requirements and/or the objectives of this plan are noted. Table 3-1 summarizes the major elements of the source control programs. The table denotes whether the City currently implements each listed element and briefly summarizes potential future program measures. Under this heading,two columns are listed. The first column summarizes future measures that maintain or expand the City's program to meet all applicable requirements of the 2002 NPDES stormwater Permit and these items are noted as "mandatory." Additional future program measures were also identified during the development of the Water Quality Element. These potential measures would enhance the program beyond the prescribed Permit requirements and are noted as"discretionary" measures. A brief description of each element follows: cm 3-1 P:N0890.Huntington BeaehU4080-WOMP-MPDV PROJDO06.Task6VAaster PlanZec0on 3 upaate.ax Section 3 City of Huntington Beach 2002 Water Quality Element Table 3-1 Summary of Source Control Program Elements Existing Program Element Program Future Program Measures Actions To Meet NPDES Potential Additional Permit Requirements Enhancement (Mandatory) (Discretionary) Legal Authority/Enforcement Yes Update ordinances as necessary Illegal Discharges/Illicit Yes Continue existing Connections Elimination enforcement program Develop construction site Construction Site Water Quality inventory,construction site Inspections Yes inspection prioritization, train inspectors, increase inspections Develop facility inventory Focus on restaurant database,facility inspection inspections,coordinate with Industrial/Commercial Water No prioritization,develop proposed County Health Quality Facilities Inspections inspection database,train Department Program,or inspectors,conduct create local City program; inspections require grease trap retrofits Support and continue Conduct local public participating with other outreach effort focused on Public Education/Outreach Yes Orange County Permittees; restaurants,schools, Conduct municipal staff Harbour area residents/live training aboards Update City procedures, Increase cleaning and activities,and training to maintenance:channels and Public Agency Activities Yes comply with Model pump station forebays; Maintenance Programs Increase street and parking under development lot sweeping;conduct street/alley sweeping 3.1.1 Legal Authority/Enforcement In order to implement programs within the City to reduce pollutants from entering receiving waters,the City has established adequate legal authority to regulate the discharge of pollutants to the municipal separate storm sewer system. Regulatory requirements promulgated by the U.S.EPA in 1990,require municipal NPDES Permit applicants,such as the City,to demonstrate having the following adequate legal authority to: ■ Control the contribution of pollutants to the municipal storm drain system by stormwater discharges associated with industrial activities ■ Prohibit illicit discharges to the municipal storm drain system ■ Prohibit spills,dumping or disposal of materials other than stormwater cm 3-2 PA10890-Hunftton BeachW680-WOMP-MPDVPR0JD0M6.Task8Wlaster Plan%SecUm 3 upoate.Coc Section 3 City of Huntington Beach 2002 Water Quality Element ■ Control through interagency agreements among the Permittees,the contribution of pollutants from one municipality into the common combined flood control and stormwater conveyance system managed by the Orange County Flood Control District. ■ Require compliance with conditions in ordinances ■ Carry out all inspections,surveillance and monitoring procedures necessary to determine compliance and noncompliance with permit conditions,and effectively prohibit illicit discharges to the municipal storm drain system The City adopted the Water Quality Ordinance and corresponding Enforcement Consistency Guide in fiscal year 1997-98. This Ordinance was developed through the coordinated efforts of the other Orange County Permittees in order to provide a more uniform countywide approach. In addition,the City has identified authorized inspectors responsible for enforcing the Ordinance. The City,in coordination with the other co-Permittees,will continue,as required,to update this ordinance to maintain adequate legal authority to implement current and future program measures. The City is currently updating the Ordinance to provide increased enforcement coverage for activities within Huntington Harbour. 3.1.2 Illegal Discharge and Illicit Connection Elimination Illegal discharges and illicit connections are potential sources of contamination entering the City's stormwater drainage system. The City's existing illegal discharge and illicit connection elimination program consists of the following: ■ Industrial facility inspections The City Fire Department currently conducts industrial facility inspections to determine if hazardous material storage practices are in compliance with standards. As discussed in Section 3.1.5,the City is now required to train inspectors and inventory and prioritize industrial facilities specifically to document water quality concerns. ■ Drainage facility inspection and documentation Under the municipal drainage facility maintenance program,as discussed in Section 3.1.6,the City field personnel document any illegal discharges or illicit connections to the storm drainage system in addition to performing drainage maintenance activities. ■ County-wide reconnaissance monitoring CM 3-3 P:\1088g-MunBngton BeaehW 884WOMP-MPD\7PR0ID0Vfi.Task6Wlasler Plen\Section 3 update.0oo Section 3 City of Huntington Beach 2002 Water Quality Element The City as a co-Permittee participates in this program in which any identified water quality problem is further determined whether to be from an illicit connection or illegal discharge through a series of source identification studies. ■ Spill reporting and response A 24-hour reporting telephone hotline and email address is published in all public education materials produced and distributed by the City. ■ Investigations/Enforcement The City designates Authorized Inspectors within the City s Public Works and City Fire Department to investigate any reported water pollution incidents. For more serious incidents,investigations are coordinated through the Orange County Hazardous Materials Strike Force. Enforcement activities may be handled on an administrative basis or through criminal enforcement. The city will continue to implement the above activities. 3.1.3 Construction Site Water Quality Inspections The Citys existing construction inspection program ensures that construction sites are complying with City-issued grading and building permit requirements. Under the new NPDES Permit requirements established in 2002,the City is required to perform the following: ■ Train construction site inspectors (public works and building) ■ Educate developers and contractors ■ Inventory all construction sites based on City-issued building and grading permits ■ Prioritize construction sites into"high,medium,and low" categories based on potential threats to water quality ■ Establish inspection criteria for high,medium,and low categories ■ Establish a construction site database maintaining inspection information ■ Conduct inspections at sites during the wet weather and dry weather seasons The City is in the process of updating the construction inspection program and will continue to comply with these required commitments. cm 3-4 P:Np88o-HunBnpton Beach\74880.WOMP-MPD%7PR0JD000.Task6W Wer Plan%SecBon 3 update.doc Section 3 City of Huntington Beach 2002 Water Quality Element 3.1.4 Industrial/Commercial Water Quality Facilities Inspections The City currently does not have a formal program of identification and outreach to industrial/commercial facilities with particular focus on water quality related issues. The City's Fire Department does perform annual inspections of facilities specifically for hazardous materials storage. A more complete program will be required to meet the new permit. Under the new Permit, the City will be required to perform the following: , ■ Inventory and develop database of industrial facilities based on filed business permits ■ Inventory and develop database of commercial facilities within specific business categories such as automobile repair stations,mobile washing operations,pool maintenance operations,landscapers,painting,etc. ■ Prioritize and inspect industrial and commercial facilities based on high,medium, or low threat to water quality ■ Conduct inspections to ensure compliance with ordinances and NPDES Permit requirements ■ Provide BMP guidance for the industrial/commercial facility inspectors to distribute The City is in the process of developing an industrial and commercial inspection program to comply with required commitments. This represents a major new program as there are over 18,000 business licenses in the City. The program will require additional staff. Alternatively,an expansion of the existing inspection program conducted by the Fire Department related to hazardous materials could be explored. Orange County PFRD is also developing a restaurant inspection program that will use staff from the County Health Department to add water quality-related issues to their existing restaurant inspection program in all jurisdictions. The intent of the program will be to provide inspection information to the cities,with enforcement,if necessary carried out at by the cities. The City can elect to participate in this program. Potential Additional Enhancement Because of the number of restaurant and food service establishments in the City,and in particular in the downtown and harbor areas,reducing water quality impacts from restaurant operations is a high priority for the City. The City will evaluate the inspection program developed by the County and determine whether to rely on the County program or supplement the program with additional inspections and enforcement. cm 3-5 PA10890-Huntington Beac W880-WDMP-MP0VPR0AD0C18.Tssk8VAa9er Ptan%Sectlon 3 update.doe Section 3 City of Huntington Beach 2002 Water Quality Element Newer restaurants have been constructed with grease traps. Many older facilities were constructed before grease traps were required by code. The City will investigate the feasibility of a program to require grease trap retrofits including consideration of technical,legal and financial issues. 3.1.5 Public Education/Outreach The City,consistent with Permit requirements,participates in educational and public information activities with other Permittees to present a consistent message on storm water pollution prevention. The goal is to inform the public and municipal staff about the origins and causes of storm water pollution and to promote behavioral changes that will help control pollutants at the source. The City conducts public education outreach to its community through a variety of means such as: ■ Public service announcements (PSAs)through television and radio ■ Community newsletters(monthly) ■ Recycling brochures (placed at Civic Center and main library and local real estate business offices) ■ Utility bill inserts(quarterly) ■ City-sponsored events with litter/debris cleanup and recycling emphasis ■ 24-hour water pollution reporting hotline ■ Tours of the Materials Recovery Facility for schools grades 3-6 ■ City website postings of educational materials The City also supports and continues to participate with the County and other Permittees on a Public Education Committee in the development of public education and outreach materials for countywide distribution to focus on public education and business activities with potentially polluting businesses. The business education element of the program consists of the distribution of BMP guidance for business activities such as mobile detailing,pool maintenance,restaurant cleaning operations, and automotive service centers. Potential Additional Enhancement The City will consider implementing targeted local public information and outreach efforts in the following areas: ■ Restaurant operations cm 3-6 PA10990-Hun ftton Beech%34880-WQMP-MPDVPR0JD0CX6.Tesk6Waster PWXSecOon 3 updete.doc Section 3 City of Huntington Beach 2002 Water Quality Element ■ Litter control in the Coastal and Harbour areas ■ Landscape and concrete construction contractors ■ School outreach programs 3.1.6 Public Agency Activities The City conducts routine preventive maintenance activities that are considered effective BMPs for pollutant control. The NPDES Permit requires documentation of these municipal activities conducted by the City. Thus,the City annually reports its public agency activities as part of its submittal to the SARWQCB. The Permittees are currently developing a program for Model Maintenance Procedures for Public Agency Activities and will continue to update its procedures, activities,and staff training to comply with this developing Model Program. The City's public agency activities that have water quality impacts include the following areas: ■ Litter Control Litter debris control is an important element in the overall effort to reduce pollutant discharges from entering the storm drain system. The City's current litter control efforts include the following: — Litter ordinance — Clean-up programs — Special/bulky item pickups — Pick-up of illegally discarded large items — Litter pick-up at sidewalks,dead-end streets,etc. — Provision of public trash receptacles The City will continue implementing these litter control efforts. Additional focused public education efforts with respect to litter control are contained in Section 3.1.5. Furthermore,as part of the current Permit,Orange County PFRD will be evaluating debris and litter control measure effectiveness on a countywide basis on behalf of the permittee. Based on the findings and recommendations of that study the City will review and update its litter control program.

The City educates the public in its efforts to emphasize recycling through its recycling kiosks located in the Civic Center and the main public library. Several City-sponsored functions emphasizing the recycling message also take place throughout the year. In addition,informational messages on proper solid waste disposal and recycling are conveyed through utility bill inserts,public service announcements (PSAs) on television and radio, community newsletters,and brochures. ■ Drainage Facility Maintenance The City maintains drainage facility inspection and maintenance procedures. The activities include maintaining inspection log sheets for documenting the total volume of material and percentages of each type of material removed from its municipal facilities. These facilities include pipes,channels,and catch basins. Specific inspection requirements are: - Inspect 80% of storm drain inlets and catch basins within City jurisdiction at least annually with 100% cumulative completion bi-annually. The Permittees are currently developing the criteria for cleaning these structures under the Model Maintenance Procedures program. - Evaluate the need for additional drainage facility diversions for dry weather flows and report annually The City will continue to perform these facility and infrastructure maintenance activities to meet the permit requirements. Potential additional Enhancement The City will evaluate a program to increase the frequency of cleaning pump station wet wells and the maintenance of existing City-owned storm drain channels. ■ Catch Basin Stenciling The City has an existing catch basin stenciling program as a part of its NPDES Permit. The label is comprised of the phrase"No Dumping-Drains to Ocean" and is stenciled on either the top of the curb or the curb face adjacent to the inlet. Each year,the City is required to report the total number of catch basins re- stenciled. The City will continue to conduct these stenciling activities to help reduce the amount of pollutants discarded directly into catch basins. cony 3-8 PA10990-Huntington BeachW0804VOMP-MPD\7PROJDOC18.Task6Wastw PlanZeclion 3 update.doc Section 3 City of Huntington Beach 2002 Water Quality Element ■ Street Sweeping The City maintains an existing street sweeping program in residential, commercial,and industrial areas. The sweeping program maintains a record of the frequency of sweeping and the weight of debris sweep on a fiscal basis. In order to increase the effectiveness of the sweeping program,parking restrictions on roadways are also utilized to further contribute to water quality improvements. Sweeping equipment is also selected based upon pollutant removal effectiveness and maintained to manufacturer's specifications. Potential Additional Enhancement Increased sweeping in areas such as parking lots and heavily traveled streets and alleys are potential opportunities for the City to focus sweeping efforts in preventing solid wastes and debris from entering the storm drain system. The City will evaluate the feasibility of expanding the sweeping/cleaning program to include these additional areas. ■ Household Hazardous Waste Collection The Orange County Integrated Waste Management Department(IWMD) administers a household hazardous waste collection program located at four sites. These sites are located in the cities of Anaheim,Huntington Beach,San Juan Capistrano,and Irvine. The collection effort also involves a Community Awareness Program that includes public presentations to schools,civic organizations,and private industry. The City implements a used oil recycling program. Containers are provided at no cost to residents for collecting used oil. The City reports to the SARWQCB in the Annual Progress Report the quantity of oil and number of oil filters collected. ■ Emergency Spill Response The City,as a co-Permittee,has enacted the authority to control releases to the storm drain system through a common Water Quality Ordinance. The City maintains a hazardous material plan outlining planned responses to hazardous materials emergencies. The plan addresses issues related to chain-of-command, other public agency participation,and the allocation of authority. The City designates an Authorized Inspector and annually reports to the SARWQCB of any sources,types, and quantity of discharge incidents. ■ Fertilizer and Pesticide Management The City implements the"Management Guidelines for Use of Fertilizers and Pesticides" as developed by the Permittees. cm 3-9 P110990-Huntlnpton BeaChN3I9e0-WOMP-MPDt7PR0JD0CXB.Task6VAaster Plan%Secdon 3 update.Aoc Section 3 City of Huntington Beach 2002 Water Quality Element The City annually reports its management and application practices for fertilizers and pesticides to include types and quantities applied. Integrated pesticide management techniques implemented are also reported. The City will continue to implement the guidelines for the management of fertilizers and pesticides and participate in any training discussing the revision of such guidelines. ■ Fixed Facility Inspections The City,under its Permit reporting requirements,will continue fixed facility annual inspections at its nine fixed facilities. At each facility,an environmental performance report documents any problems identified and corrective actions to be implemented. These sites include the following: - Beach Maintenance Yard - City Civic Center - City Corporation Yard - Gothard Fire Station#1 - Lake Fire Station - Park Tree and Landscape Yard - Police Heliport - Warner Fire Station#7 - Water Operations Yard ■ Sewer System Operation and Maintenance The City will continue to operate and maintain the sewer collection system so as to prevent overflows or leaks that could result in discharges to the storm drain system. 3.2 Program for New Development/Redevelopment New development and redevelopment of property and changes of land use within the City present unique challenges and opportunities relative to urban runoff quality management. Development or redevelopment of a property typically adds new impervious surface area that results in increased runoff and increased pollutant load. Development also creates an opportunity to incorporate design features into a project based on current stormwater management principles to fully mitigate the water quality impact of development of that property. This can be done at relatively low incremental cost compared to potentially much higher costs to construct or retrofit cm 3-10 P:%10890-Huntington Beaeh1.W80-WQMP-MPD%7PR0ID0C1A.Task6VAaster PlanZection 3 updete.doc Section 3 City of Huntington Beach 2002 Water Quality Element facilities to manage runoff quality from existing developed areas. Furthermore, management of new development/redevelopment is another core element of the City's NPDES compliance program. The component applies to both private development projects and equivalent City Capital Improvement Projects. Implementation of this program component is primarily the responsibility of property owners/developers,the City staff that oversee the planning review and approval and construction permit programs,and City Departments that undertake major new capital projects.Major program elements are briefly summarized in Table 3-2 using the same criteria as in Table 34. 3.2.1 General Plan Policies The current General Plan has limited reference to water quality goals and objectives which are currently contained in several different sections in the General Plan but not consolidated in one element. Within the Coastal Zone,the LCP does include a Water Quality Section. The General Plan requires updates to include a specific Water Quality or Water Resources Element which would include a discussion on the relationship between Water Quality and other General Plan elements such as Land Use,Urban Design,Public Facilities and Public Services,Utilities,Environmental Resources/Conservation and Coastal.

Furthermore,in compliance with the current DAMP,the City requires all new development and significant redevelopment projects to prepare a project-specific Water Quality Management Plan to identify permanent cm 3-11 P:N08a0-Nun0 glon 8each%M80-WCAAP-WDVPROMOVS.TaskOVAaster flen'Sedbn 3 update.doe Section 3 City of Huntington Beach 2002 Water Quality Element or post-construction BMPs that will be incorporated into the project's design, construction and operation. The 2002 Permit requires the County and the Co- permittee to expand and update these requirements,as well as review and update CEQA review procedures and development review processes. Orange County PFRD is preparing Model Program guidance documents to assist Cities with updating their programs. The following program elements address these requirements: ■ Revise CEQA compliance guidelines and update standard conditions of approval to coordinate with updated new development/redevelopment requirements (see next item). ■ Update process and requirements for review of new development/redevelopment Water Quality Management Plans in accordance with DAMP updates (Model Programs). ■ Establish a threshold for project size for when projects are subject to review;e.g. "small" projects that might not be subject to entitlement or discretionary reviews could be conditioned with routine design standards and review with grading/building plan submittal;larger projects would have"conceptual WQMP" reviewed during planning review,with final WQMP based on final project design in accordance with Permit and DAMP Model Program requirements. ■ Establish methodology for allowing projects to participate in regional/watershed based projects in lieu of on-site treatment controls where applicable (adopted City Water Quality Element can be basis for identifying programs). Potential Additional Enhancement The permit requirements and the DAMP model program provide guidance for WQMP standards including the quantity of runoff to be treated from new development but do not prescribe specific processes or water quality performance standards for treatment BMPs. The City will consider developing minimum treatment standards for BMPs for new development/redevelopment projects. 3.2.3 Development Standards and Requirements The City maintains planning and design standards and standard details that govern the design of projects. Standards provide for consistency with desired policies among projects and reduce the need for project-specific conditions of approval. Certain standards influence the quantity or quality of runoff from a project and design details standardize practices for common site design issues features that may also have an influence on water quality features. Examples of such design standards include: ■ Minimum landscape and pervious surface requirements cm 3-12 PAID890-Munen0ton BeaehW080-WOMP•MPDgPR0JD0CN8.Tesk8Vdester Plan%Secdon 3 update.doc Section 3 City of Huntington Beach 2002 Water Quality Element ■ Open space requirements ■ Hardscape allowance in lieu of landscape requirement ■ Commercial design standards for planter/landscaping ■ Drainage facility design standards and details Once the City's development review process and local WQMP requirements have been updated as discussed under Section 3.2.2,some of the existing standards may need to be reviewed and updated. Potential Additional Enhancement As a follow-up to updating the design review process and local WQMP requirements, a review of design standards and details will be undertaken to determine if any standards should be revised or standard design details added or modified. Alternatively,certain design standards could remain as currently adopted,with incentives incorporated in the project WQMP review and approval process such as reduced treatment requirements or reduction in drainage fees for an individual development that exceeds a standard(e.g.greater than minimum pervious surface area). 3.2.4 Specific Major Development/Redevelopment Opportunities Key properties with substantial land area that may be subject to future (near or long term) development or redevelopment should be considered as opportunities for incorporating water quality features that have additional benefits beyond just addressing project-specific impacts. These are identified by water quality planning area under Drainage Area-based Controls. 3.3 Water Quality Planning Area-based Controls This category includes structural measures or source control programs that are targeted in one particular drainage area that will provide enhanced water quality benefits beyond what could be achieved through implementation of the routine measures implemented to meet NPDES permit requirements. All of these measures can be considered discretionary. Many of these are"opportunistic' projects that take advantage of available land or natural features,potentially serve dual benefits,or have already been identified and are either under study or have been identified for possible grant funding. These potential opportunities are summarized below for each of the areas that have been identified for water quality planning purposes. General locations of the identified projects and programs are shown in Figure 3-1 where applicable. An additional city- wide concept is to evaluate the use of Edison Easements in the City for opportunities as water quality features. cm 3-13 PAI0890-Mun ington BeachW9806WQMP-MPD%7PR0JD0C%6.T83k6Waster Nen%SeWon 3 update.doe City of Huntington Beach CITY OF HUNIINGTON BEACH Water Quality Planning Area - Based Programs and Projects ��° �M FConsider CHICA CHANNEL ANAHEIM BARBER ING AREA CITY CHANNEL treatment system on NWS property.

PlankSection 3 update.doc / Section 4 1 O . — O z u� Section 4 Program Priorities Section three identifies a comprehensive set of elements to be included in a long-range Water Quality Management Program for the City of Huntington Beach. Many of the elements will require additional planning, study and substantial additional funding of capital or operating costs that are not currently budgeted. Therefore,a method of prioritizing program elements has been established for this Water Quality Element to provide direction for resource commitment and scheduling of implementation steps described in Section 5 while still keeping all viable discretionary elements in the Plan. In general, program elements fall into several broad categories including: ■ Existing program elements o Modifications to, or expansion of existing programs,and new programs required to meet current permit requirements ("mandatory elements") ■ Additional program enhancements and new projects to meet City goals and objectives ("discretionary elements") Existing programs and projects with committed funding do not need to be prioritized. For all other elements,priorities need to be established. 4.1 Priority Criteria and Categories Additional efforts that are required to meet permit requirements (mandatory elements) are considered the first priority. All other elements are currently considered discretionary and establishing priorities is beneficial. Two primary criteria that generally encompass the Water Quality Element objectives were used to both establish priority categories and to place discretionary program elements within these categories. These two criteria are: ■ AbiIity to achieve water quality goals.The decision to commit resources and funding to discretionary program elements should be weighted in favor of projects that make the greatest contribution toward reducing pollutants which affect the beneficial uses that are of highest local and regulatory concern. The criterion takes into account both the importance of the pollutants that the program element or project will effectively address and the relative magnitude of the contribution. ■ Probability of implementation. This criterion allows a qualitative comparison between program elements of the probability and ease of implementation and takes into account several of the Water Quality Element objectives. For example,a program element or project would have a high probability of implementation if it requires minimal new funding or land acquisition,is based on proven technology, cm 4-1 P M690-Hundnglon Beacht34680-WOMP-MPDVPROJD006.Task6tMaster PIWSections\Section 4.dm Section 4 City of Huntington Beach 2002 Water Quality Element has minimal permitting or other environmental requirement concerns,and provides multiple benefits that help gain support or possible supplemental funding. Conversely,projects that require substantial new capital or operational_ funds,have significant permitting issues,require new lard,or invol ve complex cooperation and fund sharing among multiple agencies or public-private partnerships may take significantly more time and resources to implement. Table 4-1 provides examples of applying the factors. Table 4-1 Factors Used for Priority of Implementation Criterion Probability of Implementation Higher Lower New Capital Costs No new capital costs High capital cost required No budgeted funds Additional O&M Costs No additional O&M costs High O&M costs required No budgeted funds Multiple benefits Water quality benefits Multi-Purpose Benefits Additional opportunities only for funding sources Regional vs. Local Benefits Multi-agency or other city City of Huntington Beach partners only Environmental Assessment and Non-complex Permitting Complex permitting Permitting Requirements requirements requirements Multi- Permitting involvement Because many of the program elements have only been developed at a conceptual level at the time this Water Quality Element was adopted,a detailed ranking or comparison is not possible or appropriate. Rather,three broad categories were established to allow an initial placement of the discretionary program elements into one of three categories. The categories include: ■ Priority 1-Program elements that are effective at addressing the highest priority water quality concerns and have a high probability of implementation ■ Priority 2-Program elements that are effective at addressing the highest priority water quality concerns but have lower probability of implementation;and program elements that have a high probability of implementation but address lower priority water quality concerns ■ Priority 3-Program elements that address lower priority water quality concerns and have a lower probability of implementation Over time,as more detailed information becomes available,the priority categories can be revised and program elements can be shifted.

Because the nature of runoff and receiving water conditions and the approach to management is substantially different between dry and wet weather conditions, the priorities were further segregated into dry weather and wet weather runoff conditions. The priorities used are as follows: High Priority Goals Dry Weather Runoff: ■ Reduce dry weather closures/postings of coastal waters adjacent to beaches and bacterial exceedance in the Harbour area by: reducing sources of bacteria, reducing or eliminating dry weather runoff discharges through diversions, infiltration or beneficial reuse,or disinfecting dry weather discharges. ■ Reduce other potentially toxic or harmful constituents in dry weather runoff including pesticides (e.g. from illegal dumping,spills,etc.). Wet Weather Runoff: ■ Minimize or eliminate trash/debris/coarse solids from discharges to beach and Harbour area. Intermediate Priority Goals Wet weather Runoff: ■ Reduce wet weather closures/postings of coastal waters adjacent to beaches by reducing sources of bacteria,or storing and recharging or treating wet weather discharges. ■ Reduce constituents of concern(suspended solids,nutrients,etc.) to inland water features,especially Huntington Lake. ■ Reduce loadings of metals in wet weather discharges to the Harbour area. Long-Term Goals Dry and Wet Weather Runoff: ■ Reduce overall loadings/concentrations of other pollutants in stormwater runoff 4.3 Prioritization of Program Elements Using the approach described above,all of the discretionary program elements and projects have been listed in the Tables 4-2 through 4-4 and initial priorities assigned.

Funding sources for Fiscal Year 2002-2003 include the General Fund (approximately 49%),sanitation fees (approximately 22%), and state grant funding(approximately 29%). To fund both new capital projects and increased operation and maintenance costs associated with both mandatory and discretionary program elements,additional sources of funding in addition to General Funds will be investigated and secured. Potential sources include: ■ State and Federal Grants and loans including: - Congressionally-directed Federal Grants - State legislative bills - Proposition 40 funding - Proposition 13 funding - Cal-fed funding - State revolving loan fund - Coastal Non-Point Source Control Program - Wetlands Recovery Projects Program - Proposition 50(if passed) ■ Funding from Adopt-A-Storm Drain Program ■ Potential Stormwater Utility Fee ■ Cost sharing arrangements with other agencies for regional/joint projects ■ City General Fund 5.4 Policy and Ordinance Development As noted in Section 3,implementation of some of the program elements depends upon adoption of new or revised City policies, standards, and ordinances. Table 5-3 summarizes key items to be reviewed and revised as necessary to support plan implementation and preliminary target dates for action.

A conceptual framework for monitoring is described below. Further details will be developed. The framework includes four principal components: ■ Plan implementation assessment ■ NPDES required monitoring and reporting ■ BMP effectiveness evaluations ■ Water quality monitoring Each of the components is briefly summarized below. 5.5.1 Water Quality Element Implementation Assessment On an annual basis,the Water Quality Element elements will be reviewed, progress summarized and the elements and priorities updated. It is anticipated that Priority 1 elements will be reviewed at a greater level of detail to identify progress made in the past year and flag any major outstanding implementation issues (e.g. funding, permits,ordinance adoption,etc.). Elements can be added or deleted, and priorities revised. The assessment should be completed after the City's NPDES annual report is completed each year(see Section 5.4.2). cm 5-7 P910690-Hunfinglon BeaW34680-WQMP-MPD\7PR0JD006.Task61,Ma6cer Plan\SWions\Se lion 5 dm Section 5 City of Huntington Beach 2002 Water Quality Element 5.5.2 NPDES Required Monitoring and Reporting Compliance with the NPDES permit and DAMP requirements requires the City to compile, summarize, and report information and progress in each of the major program areas. Orange County PFRD is in the process of updating the reporting requirements under each of the programs to comply with the new permit requirements. The 2003 Annual Report should reflect all of the new requirements. This report will provide more detailed information regarding the mandatory program elements and should be a supporting document to the Water Quality Element Implementation Assessment. 5.5.3 BMP Effectiveness Monitoring More focused evaluations of how effective individual program elements or BMPs are performing can be conducted,particularly for new programs or projects with substantial capital and/or annual expenditure investments. Many of the programmatic elements can be evaluated using the information compiled for the annual reporting discussed in Section 5.4.2. However, representative performance information on structural BMPs will also be desirable. These will be identified and implemented on a case-by-case basis and should be factored into project funding for new projects or programs. Effectiveness evaluations can include: ■ Water quality monitoring of city-owned treatment BMPs ■ Water quality monitoring of developer-installed BMPs 5.5.4 Water Quality Monitoring Regional water quality monitoring under the permit will continue to be conducted by Orange County PFRD with all of the permittees contributing to the cost of the program. This program provides regional data that is of interest to the City and can be used for general background comparisons. However,very limited local data is generated from the regional program and the three monitoring stations in the vicinity of Huntington Beach primarily sample upstream of most of the City. Therefore,some supplemental ongoing sampling by the City may be desirable. However,water quality monitoring can be very costly,particularly given the multiple watershed and drainage facilities and the very different characteristics of wet weather and dry weather flows and the ability to sample each. A limited on-going dry weather monitoring program is recommended based on utilizing knowledge gained from the sampling conducted during the development of the Water Quality Element.The program will be designed to expand upon baseline data and to develop trend analyses after more of the Priority 1 projects that focus on dry weather water quality are implemented. No local wet weather monitoring is recommended initially,other than the possibility of monitoring BMP performance as discussed under Section 5.4.3. cm 5-8 P110690-Hun6ngton BeacM34680-WOMP-MPD\7PR0JD006.Task6`,Mas1er Plan\Sec ions\Section 5 doc Section 5 City of Huntington Beach 2002 Water Quality Element 5.6 Responsibilities The City Council holds the overall responsibility for adopting the Water Quality Element and overseeing the implementation of the program elements but implementation of the program requires active involvement by most City Departments,as shown in Figure 5-1. While program responsibilities are distributed throughout the City organization,the Public Works Department has two key responsibilities: ■ Maintain, review,and update Water Quality Element and report annually to City Council and coordinate implementation of the Water Quality Element with other City Departments ■ Coordinate compliance and reporting activities under the NPDES permit and DAMP,and coordinate activities with other City Departments The City Council Water Quality Subcommittee will provide detailed liaison between the Council and City Administration and staff on the water quality program. The Public Works Commission will provide review and advice on annual Water Quality Element updates.

(These uses of water serve to promote the tangible and intangible economic,social,and environmental goals. "Beneficial Uses' of the waters of the State that may be protected against include,but are not limited to,domestic, municipal,agricultural and industrial supply;power generation;recreation;aesthetic enjoyment;navigation;and preservation and enhancement of fish,wildlife,and other aquatic resources or preserves).Existing beneficial uses are uses that were attained in the surface or ground water on or after November 28,1975;and potential beneficial uses are uses that would probably develop in future years through the implementation of various control measures. "Beneficial Uses" are equivalent to "Designated Uses" under federal law. [California Water Code Section 13050(f)]. cm A-1 Ph10800-Huidin0ton BeaW.W80-WOMP-MM7PROMOM.TeskOWaster PlsnVlosserydrefl updeted.doa Appendix A Glossary _ Best Management Practices-Best Management Practices(BMPs)are defined in 40 CFR 122.2 as schedules of activities,prohibitions of practices,maintenance procedures,and other management practices to prevent or reduce the pollution of waters of the United States.BMPs also include treatment requirements,operating procedures and practices to control plant site runoff,spillage or leaks,sludge or waste disposal,or drainage from raw material storage.In the case of municipal storm water permits,BMPs are typically used in place of numeric effluent limits. Clean Water Act Section 402(p) - [33 USC 1342(p)] is the federal statute requiring municipal and industrial dischargers to obtain NPDES permits for their discharges of storm water. Clean Water Act Section 303(d)Water Body-is an impaired water body in which water quality does not meet applicable water quality standards and/or is not expected to meet water quality standards,even after the application of technology based pollution controls required by the CWA.The discharge of urban runoff to these water bodies by the Co-permittees is significant because these discharges can cause or contribute to violations of applicable water quality standards. Contamination-As defined in the Porter-Cologne Water Quality Control Act, contamination is "an impairment of the quality of waters of the state by waste to a degree which creates a hazard to the public health through poisoning or through the spread of disease.'Contamination includes any equivalent effect resulting from the disposal of waste whether or not waters of the state are affected." Erosion-When land is diminished or warn away due to wind,water,or glacial ice. Often the eroded debris (silt or sediment) becomes a pollutant via storm water runoff. Erosion occurs naturally but can be intensified by land clearing activities such as farming, development,road building,and timber harvesting. Grading-The cutting and/or filling of the land surface to a desired slope or elevation. Illicit Discharge-Any discharge to a municipal separate storm sewer that is not composed entirely of storm water except discharges pursuant to a NPDES permit (other than the NPDES permit for discharges form the municipal separate storm sewer) and discharges resulting from fire fighting activities. MEP-MEP is the acronym for Maximum Extent Practicable. MEP is the technology- based standard established by Congress in CWA section 402(p)(3)(B)(iii) that municipal dischargers of storm water (MS4s) must meet.Technology-based standards establish the level of pollutant reductions that dischargers must achieve,typically by treatment or by a combination of treatment and best management practices (BMPs). MEP generally emphasizes pollution prevention and source control BMPs primarily (as the first line of defense) in combination with treatment methods serving as a backup (additional line of defense). MEP considers economics and is generally,but not necessarily,less stringent than BAT.A definition for MEP is not provided either in cm A-2 PA10690-Huntington Beach,. We0-WQMP-MPD\7PR0JD0C\6.Task6\Mas1er PlanVlossarydreft updated.doc Appendix A Glossary _ the statute or in the regulations.Instead the definition of MEP is dynamic and will be defined by the following process over time: municipalities propose their definition of MEP by way of their Urban Runoff Management Plan.Their total collective and individual activities conducted pursuant to the Urban Runoff Management Plan becomes their proposal for MEP. Municipal Storm Water Conveyance System- (See Municipal Separate Storm Sewer System or MS4). Municipal Separate Storm Sewer System(MS4) -MS4 is an acronym for Municipal Separate Storm Sewer System. A Municipal Separate Storm Sewer System is a conveyance or system of conveyances (including roads with drainage systems, municipal streets,catch basins,curbs, gutters,ditches,natural drainage features or channels,modified natural channels,man-made channels,or storm drains): (i) Owned or operated by a State,city town,borough,county,parish, district,association,or other public body (created by or pursuant to State law)having jurisdiction over disposal of sewage,industrial wastes, storm water,or other wastes,including special districts under State law such as a sewer district,flood control district or drainage district,or similar entity,or an Indian tribe or an authorized Indian tribal organization,or designated and approved management agency under section 208 of the CWA that discharges to waters of the United States; (ii) Designated or used for collecting of conveying storm water; (iii) Which is not a combined sewer; (iv) Which is not part of the Publicly Owned Treatment Works (POTW) as defined at 40 CFR 122.2. Historic and current development make use of natural drainage patterns and features as conveyances for urban runoff.Urban streams used in this manner are part of the municipalities MS4 regardless of whether they are natural,man-made, or partially modified features. In these cases,the urban stream is both an MS4 and receiving water. National Pollution Discharge Elimination System (NPDES) -These permits pertain to the discharge of waste to surface waters only. All State and Federal NPDES permits are also WDRs. Non Point Source (NPS)-Non point source refers to diffuse,widespread sources of pollution.These sources may be large or small,but are generally numerous throughout a watershed. Non Point Sources include but are not limited to urban, agricultural,or industrial areas,roads,highways,construction sites,communities served by septic systems,recreational boating activities,timber harvesting,mining, livestock grazing,as well as physical changes to stream channels,and habitat degradation. NPS pollution can occur year round any time rainfall,snowmelt, irrigation,or any other source of water runs over land or through the ground,picks up pollutants from these numerous,diffuse sources and deposits them into rivers, lakes, and coastal waters or introduces them into ground water. Non-Storm Water-Non-storm water consists of all discharges to and from a storm water conveyance system that do not originate from precipitation events (i.e.,all VMS■ A-3 PA1 D890-Huntington BeachVW80-WO1V1P-MPD%7PR0JD0V8.Task6Waster Plantiossarydrafl updated.doc Appendix A Glossary discharges from a conveyance system other than storm water). Non-StOTM water includes illicit discharges,non-prohibited discharges,and NPDES permitted discharges. An illicit discharge is defined at 40 CFR 122.26(b) (2) as any discharge to a municipal storm water conveyance system that is not composed entirely of storm water except discharges pursuant to a separate NPDES permit and discharges resulting from emergency fire fighting activities. Numeric effluent limitations-The typical method by which effluent limits are prescribed for pollutants in waste discharge requirements implementing the federal NPDES regulations. When numeric effluent limits are met at the"end-of-pipe", the effluent discharge generally will not cause water quality standards to be exceeded in the receiving waters (i.e.,water quality standards will also be met). Pollution-As defined in the Porter-Cologne Water Quality Control Act,pollution is "the alteration of the quality of the waters of the State by waste,to a degree that unreasonably affects the either of the following:A)The waters for beneficial uses;or B) Facilities that serve these beneficial uses." Pollution may include contamination. Pollutant-A pollutant is broadly defined as any agent that may cause or contribute to the degradation of water quality such that a condition of pollution or contamination is created or aggravated. Pollution Prevention-Pollution prevention is defined as practices and processes that reduce or eliminate the generation of pollutants,in contrast to source control, treatment,or disposal. Post-Construction BMPs-A subset of BMPs including structural and non-structural controls which detain,retain,filter,or educate to prevent the release of pollutants to surface waters during the final functional life of development. Sediment-Soil,sand,and minerals washed from land into water. Sediment resulting from anthropogenic sources (i.e.human induced land disturbance activities) is considered a pollutant. This Order regulates only the discharges of sediment from anthropogenic sources and does not regulate naturally occurring sources of sediment. Sediment can destroy fish-nesting areas,clog animal habitats,and cloud waters so that sunlight does not reach aquatic plants. Storm Water-"Storm water" is defined as urban runoff and snowmelt runoff consisting only of those discharges which originate from precipitation events. Storm water is that portion of precipitation that flows across a surface to the storm drain system or receiving waters. Examples of this phenomenon include: the water that flows off a building's roof when it rains (runoff from an impervious surface);the water that flows into streams when snow on the ground begins to melt(runoff from a semi-pervious surface);and the water that flows from a vegetated surface when rainfall is in excess of the rate at which it can infiltrate into the underlying soil(runoff from a pervious surface).When all factors are equal,runoff increases as the perviousness of a surface decreases. During precipitation events in urban areas,rain cm A-4 PA10890-Huntington Beaeh%34880-WOMP-MP0VPR0JD0CVB.Task6\Master Plan\glossarydrafl updated.doc Appendix A Glossary water picks up and transports pollutants through storm water conveyance systems, and ultimately to waters of the United States. Toxicity-Adverse responses of organisms to chemicals or physical agents ranging from mortality to physiological responses such as impaired reproduction or growth anomalies. The water quality objectives for toxicity provided in the Water Quality Control Plan,Santa Ana Region 8, (Basin Plan),state in part..."All waters shall be free of toxic substances in concentrations that are toxic to,or that produce detrimental physiological responses in human,plant,animal,or aquatic hfe....The survival of aquatic life in surface waters subjected to a waste discharge or other controllable water quality factors,shall not be less than that for the same water body in areas unaffected by the waste discharge'....Urban runoff discharges from MS4s are considered toxic when(1) the toxic effect observed in an acute toxicity test exceeds zero Toxic Units Acute (Tua=O);or(2) the toxic effect observed in a chronic toxicity test exceeds one Toxic Unit Chronic (Tuc=1). Urban runoff discharges from MS4s often contain pollutants that cause toxicity. Total Maximum Daily Load (TMDL)-The TMDL is the maximum amount of a pollutant that can be discharged into a water body from all sources (point and non- point) and still maintain water quality standards. Under Clean Water Act section 303(d),TMDLs must be developed for all water bodies that do not meet water quality standards after application of technology-based controls. Urban Runoff-Urban runoff is defined as all flows in a storm water conveyance system and consists of the following components: (1) storm water (wet weather flows) and (2)non-storm water illicit discharges (dry weather flows). Water Quality Objective-Numerical or narrative limits on constituents or characteristics of water designated to protect designated beneficial uses of the water. [California Water Code Section 13050(h)].California s water quality objectives are established by the State and Regional Water Boards in the Water Quality Control Plans.As stated in the Porter-Cologne Requirements for discharge (CWC 13263): "(Waste discharge)requirements shall implement any relevant water quality control plans that have been adopted,and shall take into consideration the beneficial uses to be protected,the water objectives reasonably required for that purpose,other waste discharges,the need to prevent nuisance,and the provisions of Section 13241." Numeric or narrative limits for pollutants or characteristics of water designed to protect the beneficial uses of the water. In other words,a water quality objective is the maximum concentration of a pollutant that can exist in a receiving water and still generally ensure that the beneficial uses of the receiving water remain protected (i.e., not impaired).Since water quality objectives are designed specifically to protect the beneficial uses,when the objectives are violated the beneficial uses are,by definition, no longer protected and become impaired.This is a fundamental concept under the Porter Cologne Act. Equally fundamental is Porter Cologne's definition of pollution. A condition of pollution exists when the water quality needed to support designated beneficial uses has become unreasonably affected or impaired;in other words,when cm A-5 PA10690-Huntington BeachVW80-VJCMP-WDVPROM00S.TeskIlWaster PlenVlossarydrafl updated.Coc Appendix A Glossary the water quality objectives have been violated. These underlying definitions (regarding beneficial use protection) are the reason why all waste discharge requirements implementing the federal NPDES regulations require compliance with water quality objectives. (Water quality objectives are also called water quality criteria in the Clean Water Act.). Water Quality Standards-are defined as the beneficial uses (e.g.,swimming,fishing, municipal drinking water supply,etc.,) of water and the water quality objectives necessary to protect those uses. Waters of the State-Any water,surface or underground,including saline waters within the boundaries of the State [California Water Code Section 13050 (e)]. The definition of the Waters of the State is broader than that for the Waters of the United States in that all water in the State is considered to be a Waters of the State regardless of circumstances or condition. Waters of the United States-Waters of the United States can be broadly defined as navigable surface waters and all tributary surface waters to navigable surface waters. Groundwater is not considered to be a Waters of the United States. As defined in the 40 CFR 122.2,the Waters of the U.S. are defined as: "(a) All waters, which are currently used,were used in the past,or may be susceptible to use in interstate or foreign commerce,including all waters which are subject to the ebb and flow of the tide;(b)All interstate waters,including interstate"wetlands;" (c) All other waters such as intrastate lakes,rivers,streams (including intermittent streams), mudflats,sandflats,"wetlands," sloughs,prairie potholes,wet meadows,playa lakes, or natural ponds the use,degradation or destruction of which would affect or could affect interstate or foreign commerce including any such waters: (1) Which are or could be used by interstate or foreign travelers for recreational or other purposes; (2) From which fish or shellfish are or could be taken and sold in interstate or foreign commerce;or (3) Which are used or could be used for industrial purposes by industries in interstate commerce; (d) All impoundments of waters otherwise defined as waters of the United States under this definition: (e)Tributaries of waters identified in paragraphs (a) through (d) of this definition; (f) The territorial seas;and(g) "Wetlands" adjacent to waters (other than waters that are themselves wetlands) identified in paragraphs (a) through(f) of this definition.Waters of the United States do not include prior converted cropland.Notwithstanding the determination of an area's status as prior converted cropland by any other federal agency,for the purposes of the Clean Water Act,the final authority regarding Clean Water Act jurisdiction remains with the EPA." Watershed-That geographical area which drains to a specified point on a water course,usually a confluence of streams or rivers (also known as drainage area, catchment,or river basin).

The City of Huntington Beach,California owns,operates,and maintains a storm drainage system for the purpose of conveying storm runoff so as to reduce or eliminate flooding under peak storm flow conditions.The storm drainage system begins with the streets and roads,and includes inlets,storm drains,open channels, pump stations,detention basins,and other appurtenances. While the primary purpose of the storm drain system is to reduce or eliminate flood hazards,the system carries both dry and wet weather urban runoff and the pollutants associated with runoff from urban land use and activities. Over the past few years,the general public and the City Council and staff have become much more aware of environmental concerns and the importance of receiving water quality and the potential impacts from urban runoff within the City of Huntington Beach. Because clean water is essential to support human and aquatic life,and recreation and tourism are major elements of the fabric and economy of the City,impairments to the local coastal waters have a major detrimental impact on the City. At the same time,regulatory requirements are increasingly focusing on non- point source pollution impacts from a wide variety of pollutants,particularly in urban. runoff from developed areas discharged from municipal storm drainage systems.and industrial and construction sites.' Recognizing the importance of managing both the quantity and quality of runoff conveyed by the storm drain system,the City of Huntington Beach is undertaking an integrated City-wide Urban Runoff Management Plan(CURMP). This initial document provides a framework for the Water Quality Element of the CURMP. The Water Quality Element provides a basis for implementing a comprehensive program for improving water quality through a combination of methods to reduce the level of urban runoff and pollutants emanating from private as well as public property and thus enhancing the quality of water discharged from the municipal storm drain system within the City. Implementation of the Water Quality Element will continue to strengthen efforts by the City to meet or exceed the requirements of the City's municipal stormwater permit and the related Orange County Drainage Area Management Plan(DAMP),anticipate other future regulatory requirements,and address water quality and other related environmental goals of the City and its residents,businesses,staff and City Council. The CURMP will include this Water Quality Element and a Drainage Element to take advantage of information developed under both efforts and identify integrated solutions that address both water quality and flood hazard protection goals. Figure 1-1 illustrates how the CURMP is comprised of the Water Quality Element and Drainage Element. cm 1-1 P110690•Hundngton Beach\34680•WOMP-MPD\7PROJD=6.Task6Wastu PIanlSWAOns\Section 1 Aat - _N Section 1 City of Huntington Beach 2002 Water Quality Element Drainage �-..

The Focus Group members included: City Council Debbie Cook,Mayor Ralph Bauer Shirley Dettloff City Staff Mary Beth Broeren,Principal Planner Geraldine Lucas,Environmental Engineer David Webb,City Engineer Cm 1-3 P:110690-Hunlinglon Beach1W80-W OMP-MPDI7PROJ0006.Task6wasler PlantSecdonslSedon 1.Coc Section 1 City of Huntington Beach 2002 Water Quality Element. r t Community Members Garry Brown,Orange County Coastkeeper Richard Harlow,.Chamber of Commerce and Development Community Victor Leipzig,Orange Coast Watch George Mason,Public Works Commission acid Southeast Huntington Beach Neighborhood Association Through the efforts of the Focus Group and Study Team,the following objectives were developed for the Water Quality Element. The Water Quality Element will guide the City's urban runoff program to improve the quality of local coastal waters, harbours, lakes and other urban waterways in order to: ■ Protect public health and safety; ■ Protect and enhance the beneficial uses such as recreation, aesthetics,economics,and habitat value of the local aquatic systems; ■ Reduce pollutants and urban runoff flows; ■ Comply with state and federal regulations; - ■ Increase public awareness and education; -" ■ Integrate water quality and drainage planning activities; ■ Efficiently use resources within the City;and ■ Achieve improved regional approaches. The framework Water Quality Element described in this document was formulated to address these objectives. While the CURMP provides a basis for managing the runoff generated from within the City of Huntington Beach,it is also important to recognize that full protection and enhancement of the water bodies requires a comprehensive regional effort on the part of numerous other public entities,private interests,and regulatory.agencies. Urban runoff in the major urban waterways and coastal waters in Huntington Beach originates from many other upstream jurisdictions. Furthermore,pollutant discharges and receiving water impacts can result from sources other than urban runoff. Therefore,adoption and implementation of a CURMP provides the City with a basis for proactive participation in regional solutions. cm 1-4 PAI D690-Hunbngtan BeS0114680-WOMP-MP0N7PR0JD0CaTeak6Wastei Plan%SedlonalSedlon t.0oe - Section 1 City of Huntington Beach 2002 Water Quality Element. i� 1.2 Plan Framework Unlike traditional water or wastewater utility services that are designed and operated to manage well-defined source waters through a single infrastructure system,urban ,runoff and the pollutants associated with the runoff originate from widely dispersed and highly varied sources,and wet weather runoff is extremely variable and episodic. Therefore,the Water Quality Element establishes a Program Framework that includes a broad combination of approaches to reduce the level of urban runoff and pollutants and enhance the quality of water discharged from the municipal storm drain system within the City. These approaches have been organized in three distinct major program components: ■ City-Wide Source Control Programs ■ Program for New Development/Significant Redevelopment ■ Watershed Planning Area-based Programs and Projects A brief summary of each of these three components are illustrated below in Figure 1-3 including a summary of the key elements,the participants or affected parties,and the types of"tools"needed to implement the elements.

Pollutant sources can originate from virtually all existing land uses and activities within the City and these programs generally are applicable city-wide. In some cases,as noted in Section 1.2.3,source control programs may include focused or customized elements applicable to certain planning areas. Many of the source control programs are existing core elements of the City's National Pollutant Discharge Elimination System (NPDES)stormWater permit compliance program and are already being effectively implemented. These source control programs will be included in the complete Water Quality Element. Program areas include: ■ Legal Authority/Enforcement ■ Public Agency Activities including: — Litter Control — Solid Waste Collection/Recycling = Drainage Facility Maintenance — Catch Basin Stenciling — Street Sweeping — Household Hazardous Waste Collection(coordinate with County program) — Emergency Spill Response — Fertilizer and Pesticide Management — Fixed Facility Inspections ■ Public Education/Outreach ■ Construction Site Water Quality Inspections ■ Industrial/Commercial Water Quality Facilities Inspections ■ Illegal Discharge and Illicit Connection Elimination ■ Sewer System Operation and Maintenance cm 1-6 PA10690-Hunengton BaWM34684W0MP•WDUPROJ0006.TaskMaster Plan%Sec5crd Section 1.0x Section 1 City of Huntington Beach 2002 Water Quality Element. The combination of these source control programs requires actions and/or are effectively implemented by almost every segment of the City including residents, tourists,businesses,contractors and staff,from many different City Departments.. . Implementation"tools"for conducting source control programs include staff time, equipment,operation and maintenance budget,ordinance adoptions and enforcement,and education and training. 1.2.2 Program for New Development/Redevelopment New development and redevelopment of property and changes of land use within the City present unique challenges and opportunities relative to urban runoff quality management. Development or redevelopment of a property typically creates or adds impervious surface area,which results in increased runoff and increased pollutant load. Development also creates an opportunity to incorporate design features into a project based on current stormwater management principles to fully mitigate the increased runoff and water quality impact of development of that property. This can be done at relatively low incremental cost compared to potentially much higher costs to construct or retrofit facilities to mange runoff from existing developed areas. Furthermore,management of new development/redevelopment is another core element of the City's NPDES compliance program. The component applies to both private development projects and equivalent City capital.improvement projects. . ( _ Implementation of this program component is primarily the responsibility of property owners/developers and the City staff that oversee the planning and construction permit programs,as well as City Departments that undertake major new capital projects. Successful execution of the program requires tools that include general plan policies and CEQA review guidelines,development standards,permit requirements and enforcement,and incremental.project cost additions borne by developers or City capital programs. In addition,certain stormwater measures that would be constructed with new projects will have long-term operation and maintenance requirements. 1.2.3 Watershed Planning Area-Based Programs and Projects This category includes structural measures or-localized source control programs that are targeted in one particular drainage area that will reduce runoff and/or provide enhanced water quality benefits beyond what can be achieved through . implementation of the typical City-wide measures implemented to meet NPDES permit requirements. Many of these are"opportunistic"projects that take advantage of available land or natural features,potentially serve dual benefits,or have already been identified and are under study as possible programs. cm 1-7 P.110690-Huntington B6ach%U680•WOMP-MPOt7PROJ0OC�6.Task6,Masta PIan1SodonslSedon Um Section 1 City of Huntington Beach 2002 Water Quality Element. City staff will generally implement watershed programs and projects;although some may be more appropriately implemented as a regional program jointly with the County of Orange and/or other upstream cities. Specific projects or programs will typically,require capital and/or operation and maintenance funding with potential for grant and loan funding,City staff time for implementation,and significant land for construction that would be either City- owned land or be acquired from private ownership. 1.2.4 Monitoring and Feedback The Water Quality Element includes a plan to provide monitoring and feedback that can be used to periodically review and update this plan. Monitoring can take a number of forms from actual field water quality monitoring to gathering and assessing program performance data so as to verify planning assumptions with actual observations. 1.2.5 Document Contents This Water Quality Element includes the following sections: ■ Section 1 provides an overview of the Water Quality Element framework. ■ Section 2 presents a brief background summary of urban runoff characteristics,the. existing drainage system and watershed setting,runoff quantity and quality,and the water quality regulatory framework. ■ Section 3 contains a detailed description of all potential elements of the plan. ■ Section 4 provides recommendations with respect to program and project priorities. ■ Section 5 presents a schedule for implementation of the Water Quality Element, discussion on potential funding sources,policy and ordinance development,and a plan for monitoring and feedback on plan implementation.

Examples of such steps include: ■ Initiating an interim dry weather runoff diversion program in both the Santa Ana River and Talbert/Huntington Beach channel areas to minimize any impact of dry weather runoff on coastal water quality. ■ Requiring source and treatment control BMPs to be incorporated in new development and redevelopment projects. ■ Implementing a number of source control measures and public education programs that meet or exceed requirements of the NPDES stormwater permit. ■ Seeking and receiving grant funding for water quality control programs including conducting this CURMP,installing treatment systems at a number of storm drain outfalls,and drainage system maintenance,and cleaning. Extensive studies have indicated that sources.such as leaking sewers are not a contributor to recent high bacterial counts in coastal waters. Additional studies conducted by the City and others are continuing to identify sources and work toward the specific objective of minimizing posting and closure of coastal waters. The Citywide Urban Runoff Management Plan(CURMP)will provide a broad framework for managing the quantity and quality of all urban runoff that reaches receiving waters from the land surfaces and through the storm drain system within the City. This Water Quality Element framework document initially focuses primarily on managing runoff quality. As drainage studies are completed,the CURMP will address water quality flood hazard and potential common solutions that can address both water quality and quantity concerns. 2.1 Urban Runoff Overview The term urban runoff as used in this Plan is defined as all flows in the storm drain system under both dry and wet weather conditions. In this context,the drainage system includes yard drains,swales,streets,curbs and gutters,storm drain inlets and catch basins,underground pipes,pump stations,open channels,lakes,detention basins,storm drain outfalls,and other designated water quality features such as vegetated swales,ravines,vegetated filter areas and wetlands. For management purposes,urban runoff has been divided into three categories summarized as follows: cm 2-1 RAI0690-Hunbngton Sexh134680-WOMP-MPDVPR0JD0U6.TasWA"er PL='Sedord Sechon 2.doc Section 2 City of Huntington Beach. 2002 Water Quality Element. ■ Dry weather urban runoff occurs throughout the year when there is no precipitation-generated runoff. Typical sources include landscape irrigation runoff;driveway and sidewalk washing;groundwater seepage;fire flow;potable water line operations and maintenance discharges;and permitted.or illegal non- storm water discharges. Dry weather runoff is principally a water quality concern.It can be a significant source of bacteria and other constituents that can be introduced through day-to-day urban activities as well as illicit discharges, dumping,or spills. Flow quantities can represent a substantial year-round volume of water discharged with associated pollutants. Furthermore,dry weather runoff quantity is an important factor that influences the ability to implement control measures such as diversion to the sanitary sewer,treatment and discharge,or reuse. Dry weather flow quantities are estimated from monitoring data and cannot be predicted using normal hydrologic projections. Drainage system capacity and condition are typically not a concern for conveying dry weather flows. ■ Small storm runoff is typically the source of a high percentage of both overall wet weather runoff volume and pollutant loads on an average annual basis. Typical design storm events used as targets for water quality management strategies are typically less than the volume generated from a one-year frequency storm event, or 10% of.the.peak flow rate of a 50-year peak storm event. Water quality design . storms are not those that produce significant flooding potential'or cause drainage system capacity deficiencies. However,planning and design of any water quality measures or Best Management Practices(BMPs) should effectively target the removal of pollutants during the more frequent small storm events as well as safely convey the peak flows. o Large storm peak runoff is of greatest concern for drainage system capacity analysis. It is not typically considered in water quality management except where natural or unlined channels have the potential for erosion under peak flows or . increasing flows resulting from development;or where flood flows can cause the release of pollutants into the drainage system such as from surcharging sanitary sewer facilities. 2.2 Existing.Drainage System The City of Huntington Beach is located adjacent to the Pacific Ocean within a heavily urbanized region of Orange County,California. Bordering cities include Seal Beach, Westminster,Fountain Valley,and Costa Mesa. Storm water discharges from the urbanized areas in Orange County consist mainly of surface runoff from residential, commercial,and industrial developments. In addition,there are storm water discharges from agricultural land uses,including farming and animal operations. Discharges from various areas within the City drain directly or indirectly into urban streams,city lakes,bays,wetlands,estuaries,and the Pacific Ocean.

From a water quality planning context,the northern portion of the county and the entire city of Huntington Beach reside within what is broadly referred to as the Lower Santa Ana River Basin under the Water Quality Control Plan(Basin Plan) adopted by the California Regional Water.Quality Control Board,Santa Ana-Region(RWQCB). The drainage area within the Lower Santa Ana River Basin and Orange County contains approximately 2.8 million residents,occupying an area of approximately 786 square miles (including unincorporated areas and the limits of 33 cities,25 of which are within the RWQCB's jurisdiction). The City resides within the following three regional Nvatersheds as designated by the Orange County Public Facilities and Resource Department Watershed and Coastal Resources Division and shown in Figure 2-1: ■ Lower Santa Ana River Watershed ■ Talbert/Greenville Banning Channel Watershed ■ Westminster Watershed Stanto Anaheim 4 ..

A small portion(slightly over one square mile) of the City drains directly to the Santa Ana River. The river begins approximately 75 miles away in the San Bernardino Mountains before crossing Orange County then ultimately emptying into the Pacific Ocean adjacent to the City as shown in Figure 22.. By contrast,the overall Santa Ana River watershed collects surface flows from approximately 1,675 square miles and can therefore have substantial influence on the local coastal waters. The Orange County portion of the Santa Ana River watershed includes portions of other cities such as Anaheim,Brea,Orange,Placentia,Santa Ana,Villa Park,and Yorba Linda. t'�¢ y n�t�allna River_ r r�, YYareBh t C E ` as • _ },.

The East Garden Grove-Wintersburg Channel drains past the Bolsa Chica Wetlands and then into Huntington Harbour.. Topography within the City ranges from just below sea level to almost-over 100 feet mean sea level with surface water flows ultimately discharging to the Pacific Ocean. The most prominent topographical features within the City are the Huntington and Bolsa Chica Mesas. The Bolsa Chica Mesa is located near the coast at the western end of the City,north of the Wintersburg Channel and south and east of Huntington Harbour. The maximum elevation of the Bolsa Chica Mesa is approximately 65 feet mean sea level. Elevations on the Huntington Mesa exceed 100 feet mean sea level. The regions surrounding the mesas within the City have surface elevations ranging from below sea level to over 25 feet mean sea level. Drainage from within the City is conveyed through streets,curbs,and gutters to a City storm drain system consisting of underground pipes,pump stations,and open channels as well as several Orange County channels. For water quality planning purposes,drainage areas within the City have been consolidated into planning areas as shown in Figure 2 3. The planning area names are based on the water body or other surface features to which they discharge. The planning watersheds as they are defined for this Water Quality Elements and their drainage areas are presented in Table 2-1. An overview of each planning area is presented below: ■ Santa Ana River Planning Area-Approximately 1.2 square miles of Huntington Beach drains to the River. Surface flows observed in the Santa Ana River are intermittent or are the result of storm water runoff immediately following a precipitation event or dry weather discharges. Most base flow in the river is captured for recharge well upstream of the City. Two storm water pump stations collect surface flows from within the City and discharge the water to the River. Currently,all dry weather flow within this area is diverted at the pump stations to the sanitary sewer system. Predominant land use in this planning area is single family residential with some multi-family residential and commercial areas as well. cm 2-5 • PA10690-Hwtnglon 8eachVW80-W0MP•MPD77PR0JD0Q6.Task61Mas1d PlanlSeCtionslSecdon 2.0oc Section 2 City of Huntington Beach 2002 Water Quality Element Table 2-1 City of Huntington Beach Water Quality Planning Areas Approximate Water Quality Drainage Area Planning Areas Miles 2 Discharge Point Regional Watershed Santa Ana River 1.2 Santa Ana River Santa Ana River Talbert Channel 7.3 Talbert Marsh Lower Santa Ana River Coastal 1.2 Huntington City Beach Bolsa Chica Wetlands 1.5 Bolsa Chica Wetlands Westminster Slater Channel 3.9 Huntington Harbour Westminster Wintersburg Channel 5.3 Huntington Harbour Westminster Harbour 3.0 Huntington Harbour Westminster Mouth of Harbour,Anaheim Bolsa Chica Channel 2.5 Bay Westminster Total 25.9 ■ Talbert Channel Planning Area-The Talbert s Marsh is a wetland roughly paralleling the inland side of Pacific Cost Highway. The x marsh receives surface flows from the Huntington Beach Channel and the Talbert Channel. Flow from the adjacent city of. �L Fountain Valley contributes to Talbert ~ Channel through the Fountain Valley Y .J Channel,which is a tributary to the Talbert ` Channel. This watershed contains eight pump storm water stations(7 City-operated/1 LA County-operated) that collects the runoff and conveys it into the two channels. Currently,all dry weather flow collected at the seven City pump stations is diverted to the sanitary sewer system. The predominant land uses in this planning area are single-family residential, commercial business,and multi-family residential. ■ Coastal Planning Area-This planning area is entirely.within the City and does not contain any City or county channels.

Land use in this planning area is predominantly newer single family residential developments with some older single and multi- family residential areas. ■ Slater Channel Planning Area- :_ This planning area lies wholly within the City and does not receiver flow from other jurisdictions. A aka large portion of surface runoff within this planning watershed flows through Talbert and = Huntington Talbert Lakes or to 2' Sully-Miller Lake. Huntington Lake and Sully-Miller Lake _ - typically hold water throughout the year while Talbert Lake generally does not. This Central Park lake system is an integral part of the City's drainage infrastructure acting as retention. The lakes are also significant from a water quality standpoint as Talbert and Huntington Lakes act as terminal lakes (no surface water exit)under small to moderate storm events and Sully-Miller Lake has no discharge except through groundwater recharge. During moderate to large storm events,stormwater discharges from Huntington Lake into Slater Channel. At the Slater pump station,the discharges are then pumped into Wintersburg Channel. The predominant land uses within this planning area include a mixture of single and multi-family residential,parks,commercial, and industrial areas. cap 2-7 P110690-Hundngton BeachU4660-WOMP-MP0I7PROJDOCl6.TaskbVMsslef PlanlSedonslSedon 2.Ooc City of Huntington Beach mT W HNTICM W" Planning Areas and.Drainage Facilities ANAHEIM BARBER CTTY CHANNEL BOLSA CH CA CHANNEL a WESTMINSTER a �/ CHANNEL NOT TO SCALE ANAHEIM BAY s -.

The Ocean View Channel collects upstream flow from the city of Fountain Valley. Within the City itself,these channels join to form the Wintersburg Channel. Further downstream,Slater Channel enters into Wintersburg Channel. The Wintersburg Channel then discharges into the Outer Bolsa Bay and then into Huntington Harbour,Anaheim Bay and the Pacific Ocean. Surface waters in the Outer Bolsa Bay,Huntington Harbour and Anaheim Bays are all under tidal influence.

These channels define the western boundary of the City and receive flow from upstream cities. The Anaheim Barber City Channel receives surface flows from the cities of cm 2-9 P.110690_Hunurgton Beach%34880-WOMP-MPDI7PR0JD006.T8Sk@Maete<PtanlSedon41Sec6an 2.Ooc Section 2 City of Huntington Beach 2002 Water Quality Element. Westminster,Garden Grove,Stanton,and Anaheim and joins the-Bolsa Chica Channel at Bolsa Chica Road between Bolsa Avenue and Westminster Boulevard. The Bolsa.Chica Channel receives surface flows from the Seal Beach Naval Weapons Station,Westminster,Seal.Beach;Garden Grove,the Armed Forces Reserve Center(Los Alamitos),Cypress,and Stanton: These combined surface flows then eventually discharge at the mouth of Huntington Harbour and to Anaheim Bay. The predominant land uses in this planning area are industrial and single family residential areas. 2.3 Runoff Quantity and Quality For runoff management planning,it is important to develop estimates of runoff quantities that need to be managed and understand the water quality of dry and wet weather runoff. Detailed estimates of runoff peak flows and volumes and pollutant load projections are being developed under the Drainage Element of the CURMP. Preliminary estimates of overall runoff volumes were derived for this Water Quality Element framework document,and general characterization of runoff quality was derived from regional water monitoring programs and a dry weather sampling program conducted during the development of this plan_ . 2.3.1 Runoff Quantity For.the CURMP,estimates of average annual runoff volumes for both dry and wet `. weather runoff were developed based on monitoring data from dry weather urban runoff and average hydrology and runoff calculations for wet weather runoff. Detailed estimates of wet weather runoff peak flows for use in evaluating drainage system needs and preliminary sizing of conveyance system improvements and major water quality projects will result from the analyses conducted under the Drainage Element. To help understand and illustrate the relative quantity of annual runoff within the City, Figure 2-4 Estimated Average Annual Flows,compares the estimated annual runoff volumes(acre-feet)within the City from both wet and dry weather runoff. Using a combination of dry weather monitoring data collected from several channel sites during the development of the Water Quality Element,previous analysis by the City of dry weather pump station operating data,and data compiled from other similar jurisdictions,an average dry weather flow factor of approximately 150 gallons per day(gpd)per acre was established for planning purposes. Using this factor the annual dry weather runoff from the roughly 26 square miles of drainage area within the City is approximately 2,800 acre-feet. Based on an 11-inch average annual rainfall and typical runoff coefficients for a mixed,relatively urbanized watershed,total long term average annual wet weather runoff from the same City drainage areas is estimated to be approximately 8,000 acre- feet. This value,however,is highly variable from year to year,depending upon seasonal rainfall patterns.

Based upon historical rainfall data in Orange County and assuming a 500-acre drainage area for comparative purposes,peak instantaneous wet weather flows can be calculated for a 2-year storm,10-year,and 50-year storm. Figure 2-5 shows that there are orders of magnitude differences in flow magnitudes between wet weather and dry weather runoff. Despite the large differences in peak flow rates,dry weather runoff is still a significant concern because it is present all year long and therefore still contributes a substantial amount of total annual volume to the drainage system and receiving waters.

Based on dry weather flow monitoring and watershed areas,it is estimated that the runoff from Huntington Beach represents about 35-40%of all flow discharged to the receiving waters through these watersheds (excluding the Santa Ana River). 2.3.2 Runoff Quality There are pollutants of concern in both wet and dry weather runoff. Information on the anticipated quality of runoff from Huntington Beach and the upstream contributing areas to the local storm drain channels comes from several sources including: ■ Recent dry weather sampling from 37 locations within the City including major channels,pump stations,significant storm drain discharge points to the channels, outfall points at the beach and wetlands,and permanent lakes (Huntington and Sully-Miller). ■ Dry and wet weather sampling at three Orange County PFRD sampling stations located inside or just upstream of the City ■ Prior sampling conducted by the City at pump stations in the Talbert/Huntington Beach Channel area CM 2-12 P.110690-Munfington Beao%34660-WOMP-MPDI7PROJDC06.Task6lMaster Planlbecaona\Secbon 2doe Section 2 City of Huntington Beach 2002 Water Quality Element ■ Prior bacteriological sampling by UCI in the Talbert/Huntington Beach Channel area ■ Regional stormwater monitoring data gathered by stormwater agencies throughout Southern California Principal dry weather pollutants of concern include: ■ Bacteria indicators. Indicator bacteria are found in all samples and are considered indicators of the possible presence of human pathogens. Densities vary widely, but are frequently found in dry weather runoff at levels greater than allowable for body contact. While the local storm drain system and channels are not designated as receiving waters with beneficial uses(except for the Santa Ana River),dry weather runoff can reach the various coastal waters where water quality objectives apply. ■ Pesticides and petroleum hydrocarbons. These compounds can potentially be found in dry weather runoff as a result of normal use and/or illegal dumping and discharge;however,dry weather sampling within the City found no detectable pesticide presence and minimal petroleum hydrocarbons. ■ Metals. Metals can potentially.be found in dry weather runoff but typically.at t levels much lower than in wet weather runoff. This is observed in sampling with most metals either not detected or detected below levels of concern inmost samples. Arsenic,cadmium,lead and nickel were below California Ocean Plan 6-month median water quality objective(most stringent standard)for almost all samples. Copper and zinc were found above the 6-month objective more than half the time, but below daily maximum in almost all samples. ■ Nutrients.Nitrogen and phosphorus are present in dry weather runoff but in generally lower levels. There are no Ocean Plan water quality objectives for nutrients,although inland lakes could be affected by excess nutrient loading. Total nitrogen is well below the nitrate-nitrogen standard for drinking water if groundwater recharge of dry weather runoff were to be considered. Wet weather runoff typically contains pollutants of concern similarly found in dry weather runoff and also contains other pollutants not typically found in dry weather runoff. However,the concentrations levels are typically higher than levels found in dry weather flows because the larger wet weather flows dislodge or carry pollutants over different surfaces that lower dry weather flows are not able to transport These pollutants of concern include: ■ Bacterial indicators. The bacterial densities are typically 1 to 2 orders of magnitude greater than in dry weather runoff.

Significant loads of trash,debris,and coarse solids can be found in wet weather urban runoff. Vegetation can be a substantial component of coarse solids. ■ Suspended solids This includes coarser to very fine sediments resulting from soil erosion and many other natural and human-activity based sources of sediment. ■ Metals. Concentrations of certain metals frequently detected in urban runoff(e.g. Copper,Lead and Zinc)can be five to ten times greater in wet weather runoff than dry weather runoff. ■ Nutrients. Nitrogen and phosphorus concentrations can be 2 to 3 times higher in wet weather runoff compared to dry weather runoff. ■ Hydrocarbons/oil and grease. Elevated levels of oil and grease and petroleum hydrocarbons can be found in wet weather runoff,particularly from streets,roads, and other paved surfaces. 2.4 Regulatory Framework Under the Clean Water Act(CWA),the state of California was originally required to develop comprehensive drainage basin plans,as a prerequisite to receiving federal — funding for the construction of municipal wastewater treatment plants. Within California,the State Water Resources Control Board(SWRCB)and its nine Regional Water Quality Control Boards (RWQCBs)are responsible for the protection of Califoniia s waters. The SWRCB sets policy statewide and the RWQCB implements the federal and state laws and regulations. The Santa Ana Regional Water Quality Control Board (SARWQCB) developed the Water Quality Control Plan(Basin Plan)for the Santa Ana Region in 1975,with subsequent updates in 1983 and 1995 and periodic amendments. The Basin Plan guides conservation and enhancement of water resources and establishes beneficial uses of inland surface waters,tidal prisms,harbours,and groundwater basins within the Santa Ana Region. The beneficial uses designated in.the Basin Plan for the City's relevant receiving waters are summarized in Table 2-2 C 2-14 P110690-Huntington Beach%-W80-WOMP-MPD%7PROJDOC%8.Ts*6%taster PlwXSedonslSecdon 20oc I Section 2 City of Huntington Beach - 2002 Water Oualify Element Table 2-2 Beneficial Uses of Project Drainages BENEFICIAL USE Ocean Waters MUN AGR IND PROC GWR NAV POW RECI REC2 COMM WARM LWRM COLD BIOL WILD RARE SPWN MAR SHELL EST Near shore Zone-San Gabriel River to Poppy Street In Corona Del Mar + X X-.

The Basin Plan contains both numerical and narrative water quality objectives that are intended to allow beneficial uses to be protected. The Basin Plan also contains an Implementation Plan that is intended to achieve the overall objectives of the Basin Plan. Two primary implementation mechanisms that affect management of urban runoff from Huntington Beach include the NPDES permit system for stormwater and the Total Maximum Daily Load process. In accordance with the CWA,an NPDES permit is required for certain municipal separate storm sewer discharges to surface waters. The City of Huntington Beach is within the region covered originally by Order No.R8-2002-0010(NPDES Permit No. CAS618030)issued by the SARWQCB on January 18,2002. The County of Orange is the principal Permittee,with Orange County Flood Control District(OCFCD)and 25 incorporated cities(Anaheim,Brea,Buena Park,Costa Mesa, Cypress,Fountain Valley,Fullerton,Garden Grove,Huntington Beach,Irvine,Laguna Woods,La Habra,La Palma,Lake Forest,Los Alamitos,Newport Beach,Orange, Placentia,Santa Ana,Seal Beach,Stanton,Tustin,Villa Park,Westminster,and Yorba Linda)within Orange County as co-Permittees. Under the permit,Permittees are required to continue implementation of the Drainage Area Management Plan(DAMP). The DAMP is the principal policy and guidance document for the countywide-NPDES storm water program. The objective' of the DAMP is to fulfill the commitment of the Permittees in presenting a plan satisfying the NPDES permit requirements and evaluating the impacts of urban stormwater quality on the beneficial uses. The DAMP contains requirements in seven general categories: ■ Public Agency Activities ■ Public Education ■ New Development/Significant Redevelopment ■ Construction :■ Industrial Discharger Identification_ ■ Detection/Elimination of Illegal Discharges and Illicit Connections ■ Water Quality Monitoring In July 1999,the SWRCB issued a new Statewide NPDES General Permit for storm water discharges associated with construction activities(General Construction Permit),in accordance with federal storm water regulations,which superseded the first General Permit issued in 1992. Developers planning construction activities as well as any city construction project disturbing an area greater than five acres are cm 2-16 P110690•Huntington 8eaohkU680-WOMP-MPD%7PROJDOC16.Task6VAastw P[wtSetEonslSCdOn 2.doe Section 2 City of Huntington Beach 2002 Water Quality Element required to file a Notice of Intent(NOI)to discharge under the Construction Activity Permit. After a NOI has been submitted,the discharger is authorized by the SWRCB to discharge storm water under the terms and conditions of the General Permit in effect at the time of application. The major provisions of the General Permit arelisted below: ■ Eliminate or reduce non-storm water discharges to storm sewer systems and other waters of the nation; ■ Develop and implement a Storm Water Pollution Prevention Plan(SWPPP);and ■ Perform inspections of storm water pollution prevention measures(control practices). By March of 2003,the Permit will be revised to reflect the Phase II stormwater regulations and the construction permit threshold will be reduced to one acre of disturbance. The City of Huntington Beach has been implementing local programs in accordance with the DAMP and the Municipal Permit since the issuance of the first DAMP in 1993. The City also has programs to ensure that developers agree to comply with the General Construction Permit. The City is.currently reviewing and will be modifying - programs to meet the updated requirements contained in the 2002 Permit. The Water Quality Element incorporates the programs required under the Permit. The relationship between federal,state,and local regulatory agencies and permits, and the City's implementation of its stormwater program is illustrated in Figure 2-6.

The purpose of the TMDL program is for states to identify streams,lakes, and coastal waters that do not meet certain water quality standards and are not expected to meet standards solely through technology-based controls of point source Cm 2-17 PAOSSO-Huntington BeacMW. 6O-WQMP-MPOt7PRo.looO6.Task6&taSW PlantSedontl3ectian 2.Eac Section 2 City of Huntington Beach 2002 Water Quality Element discharges. For such watersheds,a TMDL for the constituent(s)for which the water body is impaired must be determined. The TMDL is.a calculation of the maximurn amount of a poll utant trat a waterbody can receive and still achieve the target water quality objective: All sources of the constituent(s)must be identified and loads quantified. Load reductions are determined and then allocated among the sources. Finally,an implementation plan is prepared to achieve the load reductions. The purpose of the TMDL program is not to replace existing water po'-lution control programs,but to provide a framework for evaluating pollution control efforts and allow foi-coordination between federal,state and local efforts to meet water quality standards. Anaheim Bay and Huntington Harbour are the water bodies listed on the 1998 California 303(d)list. The TMDL priority schedule for these receiving water bodies is summarized in Table 2-3. The State Water Resources Control Board has proposed an updated 303(d)List and TMDL Priority Schedule for 2002 and is expected to adopt a new list late this year. The proposed listings affecting Huntington Beach are generally similar,but include the new listing of Huntington Beach State Park for High Coliform Count and an increase in affected area for Anaheim Bay and Huntington Harbour. . 2-18 P110690.MunBngton BeactiW680-WOMP•MPD7PROJOOGI6.Task6Masta PlanlSecdonslSecbcn 2.doc Section 2 City of Huntington Beach 2002 Water Quality Element Table 2-3 1998 California 303(d).and TMDL Priority Schedule Water Body 0 m .c0 E d c c c TMDL c c M Pollutants/ Completion Date Stressor Source Priority (Fiscal Year) P High Coliform Count Unknown High 2010/11 Urban Runoff/Storm X Metals Sewers;Unknown Medium 2010/11 Non-point Source X Metals Urban Runoff/Storm Medium 2010111 Sewers/Boat Yards Urban Runoff/Storm X Pathogens Sewers Medium 2010/11 Urban Runoff/Storm Sewers;Atmospheric Deposition; Plil Trash Recreational and Low N/A Tourism activities (non-boating); Boat DischargeslVessel Waste Unknown Non-point X X Pesticides Source Medium 2010/11 X=Listed on the 1998 California 303(d)List and TMDL Priority Schedule P=Proposed listing by the SURCB for 2002 California 303(d)List and TMDL Priority Schedule (1)=all Orange County beachesefestuaries c 2-19 P110690-Hun5ngton BeaUnWoo-WOMP-MPDt7PR0JD0QB.Taak6Wa3ter Plan\SedwiskSaUon 2.doc Section 3 (1) v f4� KtY3,l i� i ��r � 1fk+1{+� 7•�F ,�,F� j A (\/��� � . /,�/Y�``p�, �'Iy `�l�y i r fa ++�•' jc ..

Through the course of development of the Water Quality Element including Focus Group input,a wide range of potentially viable programs and projects were identified to be included in the Water Quality Element for possible implementation. As noted in Section 1,the plan elements are contained in three major categories: ■ City-Wide Source Control Programs ■ Program for New Development/Redevelopment ■ Water Quality Planning Area Programs and Projects A description of the key elements under City-Wide Source Control Programs is discussed in Section 3.1. Key elements for the New Development and Redevelopment Program are discussed in Section 3.2. Descriptions of all identified water quality planning area programs and projects are provided in Section 3.3. 3.1 City: Vide Source Control Programs This category includes a wide variety of activities and programs whose primary purpose is to prevent the introduction of pollutants to the storm drain system or receiving waters through control at the source. Pollutant sources can originate from virtually all land uses and activities within the City,and these programs generally are applicable Citywide: In some cases,source control programs may include focused or customized emphasis in certain planning areas. Most of the source control programs are existing core elements.of the City's NPDES compliance program and are already being implemented to some degree. Additional commitments to meet new Permit requirements and/or the objectives of this plan are noted. Table 3-1 summarizes the major elements of the source control programs. The table denotes whether the City currently implements each listed element and briefly summarizes potential future program measures. Under this heading,two columns are listed. The first column summarizes future measures that maintain or expand the City's program to meet all applicable requirements of the 2002 NPDES stormwater Permit and these items are noted as"mandatory." Additional future program measures were also identified during the development of the Water Quality Element. These potential measures would enhance the program beyond the prescribed Permit requirements and are noted as"discretionary' measures. A brief description of each element follows: cm 3-1 P:ND880.HunUnplon BeachW884WOMP-MPDVPROJOOCC6.Ta3k6VAAMer FUnVSeW-3 updale.d- Section 3 City of Huntington Beach 2002 Water Quality Element Table 3-1 Summary of Source Control Program Elements Existing Program Element Program Future Program Measures Actions To Meet NPDES Potential Additional Permit Requirements Enhancement (Mandatory) (Discretionary) Legal Authority I Enforcement Yes Update ordinances as necessary Illegal Discharges I Illicit Yes Continue existing Connections Elimination enforcement program Develop construction site Construction Site Water Quality inventory,construction site Yes inspection prioritization, Inspections train inspectors,increase inspections Develop facility inventory Focus on restaurant database,facility inspection inspections,coordinate with Industrial/Commercial Water No prioritization,develop proposed County Health Quality Facilities Inspections inspection database,train Department Program,or inspectors,conduct create local City program; inspections require grease trap retrofits Support and continue Conduct local public participating with other outreach effort focused on 1.

Regulatory requirements promulgated by the U.S.EPA in 1990,require municipal NPDES Permit applicants,such as the City,to demonstrate having the following adequate legal authority to: ■ Control the contribution of pollutants to the municipal storm drain system by stormwater discharges associated with industrial activities ■ Prohibit illicit discharges to the municipal storm drain system ■ Prohibit spills,dumping or disposal of materials other than stormwater cm 3-2 P:1108a0•HunMpton BeachWOWWOMP-MPDVPRQIDOC9.TasMVAaster Plan%SacUon 3 tV-re.eoa Section 3 City of Huntington Beach 2002 Water Quality Element ■ Control through interagency agreements among the Pern ttees,the contribution of pollutants from one municipality into the common combined flood control and stormwater conveyance system managed by the Orange County Flood Control District.. ■ Require compliance with conditions in ordinances ■ Carry out all inspections,surveillance and monitoring procedures necessary to determine compliance and noncompliance with permit conditions,and effectively prohibit illicit discharges to the municipal storm drain system The City adopted the Water Quality Ordinance and corresponding Enforcement Consistency Guide in fiscal year 1997-98. This Ordinance was developed through the coordinated efforts of the other Orange County Permittees in order to provide-a more uniform countywide approach. In addition,the City has identified authorized inspectors responsible for enforcing the Ordinance. The City,in coordination with the other co-Permittees,will continue,as required,to update this ordinance to maintain adequate legal authority to implement current and future program measures. The City is currently updating the Ordinance to provide increased enforcement coverage for activities within Huntington Harbour. 3.1.2 Illegal Discharge and Illicit Connection Elimination Illegal discharges and illicit connections are potential sources of contamination entering the City's stormwater drainage system. The City's existing illegal discharge and illicit connection elimination program consists of the following: ■ Industrial facility inspections The City Fire Department currently conducts industrial facility inspections to determine if hazardous material storage practices are in compliance with standards. As discussed in Section 3.1.5,the City is now required to train inspectors and inventory and prioritize industrial facilities specifically to document water quality concerns. ■ Drainage facility inspection and documentation Under the municipal drainage facility maintenance program,as discussed in Section 3.1.6,the City field personnel document any illegal discharges or illicit connections to the storm drainage system in addition to performing drainage maintenance activities. ■ County-wide reconnaissance monitoring CM 3-3 P:U0800-WundrQlan Baaeh13080.WOMP•MP 7PROJDOON.TaskSVAesterPWflSeedon 3 Wdate.doc Section 3 City of Huntington Beach 2002 Water Quality Element The City as a co-Permittee participates in this program in which any identified water quality problem is further determined whether to be from an illicit connection or illegal discharge through a series of source identification studies. 01 Spill reporting and response A 24-hour reporting telephone hotline and email address is published in all public . education materials produced and distributed by the City. ■ Investigations/Enforcement The City designates Authorized Inspectors within the City's Public Works and City Fire Department to investigate any reported water pollution incidents. For more serious incidents,investigations are coordinated through the Orange County Hazardous Materials Strike Force. Enforcement activities may be handled on an administrative basis or through criminal enforcement. The city will continue to implement the above activities. 3.1.3 Construction Site Water Quality Inspections The City's existing construction inspection program ensures that construction sites are - complying with City-issued grading and building permit requirements. Under the new NPDES Permit requirements established in 2002,the City is required to perform . the following: ■ Train construction site inspectors(public works and building) ■ Educate developers and contractors ■ Inventory all construction sites based on City-issued building and grading permits ■ Prioritize construction sites into"high,medium,and low"categories based on potential threats to water quality ■ .Establish inspection criteria for high,medium,and low categories ■ Establish a construction site database maintaining inspection information ■ Conduct inspections at sites during the wet weather and dry weather seasons The City is in the process of updating the construction inspection program and will continue to comply with these required commitments. cm 3-4 PA10890-Hunftton BeachW8804WOMP-MPD%7PRGJDOCNS.Ta"Wasttr Ptan%-e On 3 Vdate.doc Section 3 City of Huntington Beach 2002 Water Quality Element 3.1.4 Industrial/Commercial Water Quality Facilities Inspections The City currently does not have a formal program of identification and outreach to industrial/commercial facilities with particular focus on water quality related issues. The City's Fire Department does perform annual inspections.of facilities specifically .. . for hazardous materials storage. A more complete program will be required to meet the new permit. Under the new Permit,the City will be required to perform the following: ■ Inventory and develop database of industrial facilities based on filed business permits ■ Inventory and develop database of commercial facilities within specific business categories such as automobile repair stations,mobile washing operations,pool maintenance operations,landscapers,painting,etc. ■ Prioritize and inspect industrial and commercial facilities based on high,medium, or low threat to water quality ■ Conduct inspections to ensure compliance with ordinances and NPDES Permit requirements ■ Provide BIVT guidance for the industrial/commercial facility inspectors to distribute The City is in the process of developing an industrial and commercial inspection program to comply with required commitments. This represents a major new program as there are over 18,000 business licenses in the City. The program will require additional staff. Alternatively,an expansion of the existing inspection program conducted by the Fire Department related to hazardous materials could be explored. Orange County PFRD is also developing a restaurant inspection program that will use staff from the County Health Department to add water quality-related issues to their existing restaurant inspection program in all.jurisdictions. .The intent of the program will be to provide inspection information to the cities,with enforcement,if necessary carried out at by the cities. The City can elect to participate in this program. Potential Additional Enhancement Because of the number of restaurant and food service establishments in the City,and in particular in the downtown and harbor areas,reducing water quality impacts from restaurant operations is a high priority for the City. The City will evaluate the inspection program developed by the County and determine whether to rely on the County program or supplement the program with additional inspections and enforcement.

Many older facilities were constructed before grease traps were required by code. The City will investigate the feasibility of a program to require grease trap retrofits including consideration of technical,legal and financial issues: 3.1.5 Public Education/Outreach The City,consistent with Permit requirements,participates in educational and public information activities with other Permittees to present a consistent message on storm water pollution prevention. The goal is to inform the public and municipal staff about the origins and causes of storm water pollution and to promote behavioral changes that will help control pollutants at the source. The City conducts public education outreach to its community through a variety of means such as: a Public service announcements (PSAs)through television and radio ■ Community newsletters(monthly) e Recycling brochures (placed at Civic Center and main library and local real estate business offices) • Utility bill inserts(quarterly) ■ City-sponsored events with litter/debris cleanup and recycling emphasis ■ 24-hour water pollution reporting hotline ■ Tours of the Materials Recovery Facility for schools grades 3-6 ■ City website postings of educational materials The City also supports and continues to participate with the County and other Permittees on a Public Education Committee in the development of public education and outreach materials for countywide distribution to focus on public education and .. business activities with potentially polluting businesses. .The business education . element of the program consists of the distribution of BMP guidance for business activities such as mobile detailing,pool maintenance,restaurant cleaning operations, and automotive service centers. Potential Additional Enhancement The City will consider implementing targeted local public information and outreach efforts in the following areas: ■ Restaurant operations cm s-s P.%10690•H.,O ton BeaNW"O-WQW-Mp-pROMOC`B.TaskoWarix Ran%Saetbn 3 updata.doe _A Section 3 City of Huntington Beach 2002 Water Quality Element ■ Litter control in the Coastal and Harbour areas ■ Landscape and concrete construction contractors ■ School outreach programs 3.1.6 Public Agency Activities The City conducts routine preventive maintenance activities that are considered effective BMPs for pollutant control. The NPDES Permit requires documentation of these municipal activities conducted by the City. Thus,the City annually reports its public agency activities as part of its submittal to the SARWQCB. The Permittees are currently developing a program for Model Maintenance Procedures for Public Agency Activities and will continue to update its procedures, activities,and staff training to comply with this developing Model Program The City's public agency activities that have water quality impacts include the following areas: ■ Litter Control Litter debris control is an important element in the overall effort to reduce pollutant discharges from.entering the storm.dram system. The City's current litter control efforts include the following: — Litter ordinance — Clean-up programs — Special/bulky item pickups — Pick-up of illegally discarded large items — Litter pick-up at sidewalks,dead-end streets,etc. - Provision of public trash receptacles The City will continue implementing these litter control efforts. Additional focused public education efforts with respect to litter control are contained in Section 3.1.5. Furthermore,as part of the current Permit,Orange County PFRD will be evaluating debris and litter control measure effectiveness on a countywide basis on behalf of the permittee. Based on the findings and recommendations of that study the City will review and update its litter control program. cm 3-7 PAI0580•Hundngton SearhW9E0-WOMP•MPDVPR0JD0Vfi.T43k6Waater KWNSetdon 3 update.doe Section 3 City of Huntington Beach 2002 Water Quality Element ■ Solid Waste Collection/Recycling The City has existing solid waste collection programs for public,residential, commercial,and industrial areas. The City educates the publicin its efforts to emphasize recycling through its recycling kiosks located in the Civic Center and the main public library. Several City-sponsored functions emphasizing the recycling message also take place throughout the year. In addition,informational messages on proper solid waste disposal and recycling are conveyed through utility bill inserts,public service announcements(PSAs)on television and radio, community newsletters,and brochures. ■ Drainage Facility Maintenance The City maintains drainage facility inspection and maintenance procedures. The activities include maintaining inspection log sheets for documenting the total volume of material and percentages of each type of material removed from its municipal facilities. These facilities include pipes,channels,and catch basins. Specific inspection requirements are: - Inspect 80% of storm drain inlets and catch basins within City jurisdiction at least annually with.100%cumulative completion bi-annually. The Permittees are currently developing the criteria for cleaning these structures under the Model Maintenance Procedures program: Evaluate the need for additional drainage facility diversions for dry weather flows and report annually The City will continue to perform these facility and infrastructure maintenance activities to meet the permit requirements. Potential additional Enhancement The City will evaluate a program to increase the frequency of cleaning pump station wet wells and the maintenance of existing City-owned storm drain channels. ■ Catch Basin Stenciling The City has an existing catch basin stenciling program as a part of its NPDES Permit. The label is comprised of the phrase"No Dumping-Drains to Ocean" and is stenciled on either the top of the curb or the curb face adjacent to the inlet. Each year,the City is required to report the total number of catch basins re- stenciled. The City will continue to conduct these stenciling activities to help reduce the amount of pollutants discarded directly into catch basins. cm 3-8 P:110590.HungVon BeachWBEaWOMP-MPDVMOJDOCCS.TaakBV."er Plan%SecBon 3 updaledoc Section 3 City of Huntington Beach 2002 Water Quality Element ■ Street Sweeping The City maintains an existing street sweeping program in residential, commercial,and industrial areas. The sweeping program maintains a record of the frequency of sweeping and the weight of debris sweep on a fiscal basis. In order.to increase the effectiveness of the sweeping program,parking restrictions on roadways are also utilized to further contribute to water quality improvements. Sweeping equipment is also selected based upon pollutant removal effectiveness and maintained to manufacturer's specifications. Potential Additional Enhancement Increased sweeping in areas such as parking lots and heavily traveled streets and alleys are potential opportunities for the City to focus sweeping efforts in preventing solid wastes and debris from entering the storm drain system. The City will evaluate the feasibility of expanding the sweeping/cleaning program to include these additional areas. ■ Household Hazardous Waste Collection The Orange County Integrated Waste Management Department(IWMD) administers a household hazardous waste collection program located at four sites.. These sites are located in the cities of Anaheim,Huntington Beach,San Juan Capistrano,and Irvine. The collection effort also involves a Community Awareness Program that includes public presentations to schools,civic organizations,and private industry. The City implements a used oil recycling program. Containers are provided at no cost to residents for collecting used oil. The City reports to the SARWQCB in the Annual Progress Report the quantity of oil and number of oil filters collected. ■ Emergency Spill Response The City,as a co-Permittee,has enacted the authority to control releases to the storm drain system through a common Water Quality Ordinance. The City maintains a hazardous material plan outlining planned responses to hazardous materials emergencies. The plan addresses issues related to chain-of-command; other public agency participation,and the allocation of authority. The City designates an Authorized Inspector and annually reports to the SARWQCB of any sources,types,and quantity of discharge incidents. ■ Fertilizer and Pesticide Management The City implements the"Management Guidelines for Use of Fertilizers and Pesticides"as developed by the Permittees. Cm 3-9 Pt\70690•Hw*lgtonBeschZ4W0-WQW•MPoVPRojoM)B-Smk6WWOrRen%Sedbn3updeteAoe t Section 3 City of Huntington Beach 2002 Water Quality Element The City annually reports its management and application practices for fertilizers and pesticides to include types and quantities applied. Integrated pesticide management techniques implemented are also reported. The City will continue to implement the guidelines for the management of fertilizers and pesticides and participate in any training discussing the revision of such guidelines. ■ Fixed Facility Inspections The City,under its Permit reporting requirements,will continue fixed facility annual inspections at its nine fixed facilities. At each facility,an environmental performance report documents any problems identified and corrective actions to be implemented. These sites include the following- - Beach Maintenance Yard - City Civic Center - City Corporation Yard - Gothard Fire Station#1 - Lake Fire Station - Park Tree and Landscape Yard Police Heliport Warner Fire Station#7 Water Operations Yard ■ Sewer System Operation and Maintenance The City will continue to operate and maintain the sewer collection system so as to prevent overflows or leaks that could result in discharges to the storm drain system. 3.2 Program for New DevelopmenWedevelopment New development and redevelopment of property and changes of land use within the City present unique challenges and opportunities relative to urban runoff quality management. Development or redevelopment of a property typically adds new impervious surface area that results in increased runoff and increased pollutant load. Development also creates an opportunity to incorporate design features into a project based on current stormwater management principles to fully mitigate the water quality impact of development of that property. This can be done at relatively low incremental cost compared to potentially much higher costs to construct or retrofit cm 3-10 P.%10890.H%3n%V0n Beach,9U 80-WOUP-MPWPROJOOL"A.TaskOWBeNPlan%sadlon 3 epdate.doo -_tt Section 3 City of Huntington Beach 2002 Water Quality Element facilities to manage runoff quality from existing developed areas.-Furthermore, management of new development/redevelopment is another core element of the City's NPDES compliance program. The component applies to both private development projects and equivalent City Capital Improvement Projects. - Implementation of this program component is primarily the responsibility of property owners/developers,the City staff that oversee the planning review and approval and construction permit programs,and City Departments that undertake major new capital projects.Major program elements are briefly summarized in Table 3-2 using the same criteria as in Table 3-1. 3.2.1 General Plan Policies The current General Plan has limited reference to water quality goals and objectives which are currently contained in several different sections in the General Plan but not consolidated in one element. Within the Coastal Zone,the LCP does include a Water Quality Section. The General Plan requires updates to include a specific Water Quality or Water Resources Element which would include a discussion on the relationship between Water Quality and other General Plan elements such as Land Use,Urban Design,Public Facilities and Public Services,Utilities,Environmental Resources/Conservation and Coastal.

Furthermore,in compliance with the current DAMP,the City requires all new development and significant redevelopment projects i to prepare a project-specific Water Quality Management Plan to identify permanent cm 3-11 P170690-Hun%Von 9ead1W680-WQMP-MPOVMOJOOC`6.T83k6Wa5tef PlanNSaWon 3 update.doe Section 3 City of Huntington Beach 2002 Water Quality Element t: or post-construction BMPs that will be incorporated into the project's design, construction and operation. The 2002 Permit requires the County and the Co- permittee to expand and update these requirements,as well as review and update CEQA review procedures and development review processes. Orange County'PFRD is preparing Model Program guidance.documents to assist Cities with updating their. programs. The following program elements address these requirements: ■ Revise CEQA compliance guidelines and update standard conditions of approval to coordinate with updated new development/redevelopment requirements (see next item). ■ Update process and requirements for review of new development/redevelopment Water Quality Management Plans in accordance with DAMP updates (Model Programs). ■ Establish a threshold for project size for when projects are subject to review;e.g. "small" projects that might not be subject to entitlement or discretionary reviews could be conditioned with routine design standards and review with grading/building plan submittal;larger projects would have."conceptual WQMPr'xeviewed during planning review,with final WQMP based.on final` (. project design in accordance with Permit and DAMP Model Program requirements. ■ Establish methodology for allowing projects to participate in regional/watershed based projects in lieu of on-site treatment controls where applicable(adopted City Water Quality Element can be basis for identifying programs). Potential Additional Enhancement The permit requirements and the DAMP model program provide guidance for WQMP standards including the quantity of runoff to be treated from new development but do not prescribe specific processes or water quality performance standards for treatment BMPs. The City will consider developing minimum treatment standards for BMPs for new development/redevelopment projects. 3.2.3 Development Standards and.Requirements The City maintains planning and design standards and standard details that govern the design of projects. Standards provide for consistency with desired policies among projects and reduce the need for project-specific conditions of approval. Certain standards influence the quantity or quality of runoff from a project and design details standardize practices for common site design issues features that may also have an influence on water quality features. Examples of such design standards include: ■ Minimum landscape and pervious surface requirements cm 3-12 P:110890•Hunlinglon BeaMWBeo-VVQW•LVDVMOJDOC'e-Te3kg%l"er Plan\Sedbn 9 update.doe Section 3 City of Huntington Beach 2002 Water Quality Element ■ Open space requirements ■ Hardscape allowance in lieu of landscape requirement ■ Commercial design standards for planter/landscaping ■ Drainage facility design standards and details Once the City's development review process and local WQMP requirements have been updated as discussed under Section 3.2.2,some of the existing standards may need to be reviewed and updated. Potential Additional Enhancement As a follow-up to updating the design review process and local WQMP requirements, a review of design standards and details will be undertaken to determine if any standards should be revised or standard design details added or modified. Alternatively,certain design standards could remain as currently adopted,with incentives incorporated in the project WQMP review and approval process such as reduced treatment requirements or reduction in drainage fees for an individual development that exceeds a standard(e.g.greater than minimum pervious surface area). 1124Specific M.".or Develo men edevelo ment Opportunities Key properties with substantial land area that may be subject to future (near or long term) development or redevelopment should be considered as opportunities for incorporating water quality features that have additional benefits beyond just addressing project-specific impacts. These are identified by water quality planning area under Drainage Area-based Controls. 3.3 Water Quality Planning Area-based Controls This category includes structural measures or source control programs that are targeted in one particular drainage area that will provide enhanced water quality benefits beyond what could be achieved through implementation of the routine measures implemented to meet NPDES permit requirements. All of these measures can be considered discretionary. Many of these are"opportunistic"projects that take advantage of available land or natural features,potentially serve dual benefits,or have already been identified and are either under study or have been identified for possible grant funding. These potential opportunities are summarized below for each of the areas that have been identified for water quality planning purposes. General locations of the identified projects and programs are shown in Figure 3-1 where applicable. An additional city- wide concept is to evaluate the use of Edison Easements in the City for opportunities as water quality features. cm 3-13 PA10690•Hurftgton BeachW dd6WOMP•MPDM ROJDOCW.TaskSWasler Plan%SacUon 3 updale.doe City of Huntington Beach Cff W 1fUNIWM SERH Water Quality Planning Area-Based Programs and Projects VORKS� . .

Section 4 Program Priorities Section three identifies.a comprehensiveset.of elements to be included in a long-range Water Quality Management Program for the City of Huntington Beach: Many of the elements will require additional planning,study and substantial additional funding of capital or operating costs that are not currently budgeted. Therefore,a method of prioritizing program elements has been established for this Water Quality Element to provide direction for resource commitment and scheduling of implementation steps described in Section 5 while still keeping all viable discretionary elements in the Plan. In general,program elements fall into several broad categories including: ■ Existing program elements ■ Modifications to,or expansion of existing programs,and new programs required to meet current permit requirements ("mandatory elements") ■ Additional program enhancements and new projects to meet City goals and objectives("discretionary elements") Existing programs and projects with committed funding do not need to be prioritized. . ( For all other elements,priorities need to be established. 4.1 Priority Criteria and Categories Additional efforts that are required to meet permit requirements(mandatory elements)are considered the first priority. All other elements are currently considered discretionary and establishing priorities is beneficial. Two primary criteria that generally encompass the Water Quality Element objectives were used to both establish priority categories and to place discretionary program elements within these categories. These two criteria are: ■ Ability to achieve water quality goals.The decision to commit resources and funding to discretionary program elements should be weighted in favor of projects that make the greatest contribution toward reducing pollutants which affect the beneficial uses that are of highest local and regulatory concern. The criterion takes into account both the importance of the pollutants that the program element or project will effectively address and the relative magnitude of the contribution. ■ Probability of implementation. This criterion allows a qualitative comparison between program elements of the probability and ease of implementation and takes into account several of the Water Quality Element objectives. For example,a program element or project would have a high probability of implementation if it requires minimal new funding or land acquisition,is based on proven technology, c 4-1 PA10690•Hun7n9ton Beach\34880-WOV2-h1PD%7PROJDO06.T8sk6\Maatet PIanlSedon3%SecBon 4-doe Section 4 City of Huntington Beach 2002 Water Quality Element has minimal permitting or other environmental requirement concerns,and provides multiple benefits that help gain support or possible supplemental funding. Conversely,projects that require substantial new capital or operational funds,have significant permitting issues,require new land,or involve complex cooperation and fund sharing among multiple agencies or public-private partnerships may take significantly more time and resources to implement. Table 4-1 provides examples of applying the factors. Table 4-1 Factors Used for Priority of Implerentation Criterion Probability of Implementation Higher Lower New Capital Costs No new capital costs High capital cost required No budgeted funds Additional O&M Costs No additional O&M costs High O&M costs required No budgeted funds Multiple benefits Water quality benefits Multi-Purpose Benefits Additional opportunities only for funding sources Regional vs.Local Benefits Multi-agency or other city City of Huntington Beach partners only Environmental Assessment and Non-complex Permitting Complex permitting. Permitting Requirements requirements requirements Multi- Permitting involvement Because many of the program elements have only been developed at a conceptual level at the time this Water Quality Element was adopted,a detailed ranking or comparison is not possible or appropriate. Rather,three broad categories were established to allow an initial placement of the discretionary program elements into one of three categories. The categories include: ■ Priority 1-Program elements that are effective at addressing the highest priority water quality concerns and have a high probability of implementation ■ Priority 2-Program elements that are effective at addressing the highest priority water quality concerns but have lower probability of implementation;and program elements that have a high probability of implementation but address lower priority water quality concerns ■ Priority 3-Program elements that address lower priority water quality concerns and have a lower probability of implementation Over time,as more detailed information becomes available,the priority categories can be revised and program elements can be shifted.

Because.the nature of runoff and receiving.water conditions and the approach to management is substantially different between dry and wet weather conditions,the priorities were further segregated into dry weather and wet weather runoff conditions. The priorities used are as follows: High Priority Goals Dry Weather Runoff: ■ Reduce dry weather closures/postings of coastal waters adjacent to beaches and bacterial exceedance in the Harbour area by:reducing sources of bacteria, reducing or eliminating dry weather runoff discharges through diversions, infiltration or beneficial reuse,or disinfecting dry weather discharges. ■ Reduce other potentially toxic or harmful constituents in dry weather runoff including pesticides(e.g.from illegal dumping,spills,etc.). Wet Weather Runoff: ■` Minimize or eliminate.trash/debris/coarse solids from discharges to beach and l . Harbour area. Intermediate Priority Goals Wet weather Runoff: ■ Reduce wet weather closures/postings of coastal waters adjacent to beaches by reducing sources of bacteria,or storing and recharging or treating wet weather discharges. ■ Reduce constituents of concern(suspended solids,nutrients,etc.)to inland water features,especially Huntington Lake. ■ Reduce loadings of metals in wet weather discharges to the Harbour_area. Long-Term Goals Dry and Wet Weather Runoff: ■ Reduce overall loadings/concentrations of other pollutants in stormwater runoff 4.3 Prioritization of Program Elements Using the approach described above,all of the discretionary program elements and projects have been listed in the Tables 4-2 through 4-4 and initial priorities assigned. 4-3 P110690-Huntington BeachlS4660-WOMP-MP017PROJD0Q6.Tesk6U. 9er PIWISecdon"ecBan 440C Section 4 City of Huntington Doach 2002 Water Quality Element Table 42 Program Element.Priorities City Wide Source Control Programs Achievement of Water Quality Goals Program Element Relative Probability of Priority Goals addressed Implementation Category Effectiveness Enhanced Restaurant Inspections Dry weather bacteria;dry weather flow;other dry Moderate High-may require 1 weather pollutants additional staff Dry weather bacteria;dry weather flow and; Low—unless Restaurant Grease Trap Retrofits Moderate incentives 2 pollutants provided New Local Education Programs Dry weather other pollutants;wet weather trash Moderate High 1 and other pollutants 1-Planning Moderate— Areas Draining Increased Pump Station Wet Well Cleaning Wet weather other pollutants and metals Moderate-High increased O&M to Harbour cost 2—Other areas Moderate— Increased channel Maintenance Trash and Debris,other wet weather pollutants Moderate increased O&M 2 cost 4-4 P110690-HwWngton B83ch%34600-WOMP-MPO7PROJDOCI&Task6tMaster PlaMSec6ons1Sedw 4.Coe - -- Section 4 City of Huntington Beach 2002 Water Quality Element Table 4.3 Program Element Priorities Program for New Development/Redevelopment Achievement of Water Quality Goals Program Element Relative Probability of Priority Goals addressed Implementation .

Funding sources for Fiscal Year 2002-2003 include the'Genera.1 Fund(approximately.49%o),sanitation fees (approximately 22%),and state grant funding(approximately 29%). To fund both new capital projects and increased operation and maintenance costs associated with both mandatory and discretionary program elements,additional sources of funding in addition to General Funds will be investigated and secured. Potential sources include: ■ State and Federal Grants and loans including:e - Congressionally-directed Federal Grants - State legislative bills - Proposition 40 funding - Proposition 13 funding - Cal-fed funding ( = .

AA conceptual framework for monitoring is described below. Further details will be developed. The framework includes four - principal components: ■ Plan implementation assessment ■ NPDES required monitoring and reporting ■ BMP effectiveness evaluations ■ Water quality monitoring Each of the components is briefly summarized below. 5.5.1 Water Quality.Element Implementation Assessment On an annual basis,the Water Quality Element elements will be reviewed,progress summarized and the elements and priorities updated. It is anticipated that Priority 1 elements will be reviewed at a greater level of detail to identify progress made in the past year and flag any major outstanding implementation issues(e.g.funding, permits,ordinance adoption,etc.). Elements can be added or deleted,and priorities revised. The assessment should be completed after the City's NPDES annual report is completed each year(see Section 5.4.2). cm 5-7 PM 0690-Huntnoon BeachkW80-WOMP-MPDVPR0JD0Q6.TaskM1asler PianvSecfioniASacSon 5.doc Section 5 City of Huntington Beach 2002 Water Quality Element 5.5.2 NPDES Required Monitoring and Reporting Compliance with the NPDES permit and DAMP requirements requires the City to compile,summarize,and report information and progress in.each of the major program areas. Orange County PFRD is in the process of updating the reporting requirements under each of the programs to comply with the new permit requirements. The 2003 Annual Report should reflect all of the new requirements. This report will provide more detailed information regarding the mandatory program elements and should be a supporting document to the Water Quality Element Implementation Assessment. 5.5.3 BMP Effectiveness Monitoring More focused evaluations of how effective individual program elements or BMPs are performing can be conducted,particularly for new programs or projects with substantial capital and/or annual expenditure investments. Many of the programmatic elements can be evaluated using the information compiled for the annual reporting discussed in Section 5.4.2. However,representative performance information on structural BMPs will also be desirable. These will be identified and implemented on a case-by-case basis and should be factored into project funding for new projects or programs. Effectiveness evaluations can include: Water quality_monitoring of city-owned treatment BMPs . ■ Water quality monitoring of developer-installed BMPs 5.5.4 Water Quality Monitoring Regional water quality monitoring under the permit will continue to be conducted by Orange County PFRD with all of the permittees contributing to the cost of the program. This program provides regional data that is of interest to the City and can be used for general background comparisons. However,very limited local data is generated from the regional program and the three monitoring stations in the vicinity of Huntington Beach primarily sample upstream of most of the City. Therefore,some supplemental ongoing sampling by the City may be desirable. However,water quality monitoring can be very costly,particularly given the multiple watershed and drainage facilities and the very different characteristics of wet weather and dry. weather.flows and the ability to sample each. A limited on-going dry weather monitoring program is recommended based on utilizing knowledge gained from the sampling conducted during the development of the Water Quality Element.The program will be designed to expand upon baseline data and to develop trend analyses after more of the Priority 1 projects that focus on dry weather water quality are implemented. No local wet weather monitoring is recommended initially,other than the possibility of monitoring BMP performance as discussed under Section 5.4.3. 5-8 PA10690-Huntington 8each194680-WOMP-MP017PR0J0W6.Task5A1astw PWASedonYSeGon 5 dac Section 5 City of Huntington Beach 2002 Water Quality Element 5.6 Responsibilities The City Council holds the overall responsibility for adopting the Water Quality Element and overseeing the implementation of the.program elements but implementation of the program requires active involvement by most City Departments,as shown in Figure 5-1. While program responsibilities are distributed throughout the City organization,the Public Works Department has two key responsibilities: ■ Maintain,review,and update Water Quality Element and report annually to City Council and coordinate implementation of the Water Quality Element with other City Departments ■ Coordinate compliance and reporting activities under the NPDES permit and DAMP,and coordinate activities with other City Departments The City Council Water Quality Subcommittee will provide detailed liaison between the Council and City Administration and staff on the water quality program. The Public Works Commission will provide review and advice on annual Water Quality Element updates.

Clean Water Act Section 402(p) - [33 USC 1342(p)] is the federal statute requiring municipal and industrial dischargers to obtain NPDES permits for their discharges of storm water. Clean Water Act Section 303(d)Water Body-is an impaired water body in which water quality does not meet applicable water quality standards and/or is not expected to meet water quality standards,even after the application of technology based pollution controls required by the CWA.The discharge of urban runoff to these water bodies by the Co-permittees is significant because these discharges can cause or contribute to violations of applicable water quality standards. Contamination-As defined in the Porter-Cologne Water Quality Control Act, contamination is"an impairment of the quality of waters of the state by waste to a degree which creates a hazard to the public.health through poisoning or through the. . spread of disease 'Contamination'includes any equivalent effect resulting from the disposal of waste whether or not waters of the state are affected." Erosion-When land is diminished or warn away due to wind,water,or glacial ice. Often the eroded debris (silt or sediment)becomes a pollutant via storm water runoff. Erosion occurs naturally but can be intensified by land clearing activities such as farming,development,road building,and timber harvesting. Grading-The cutting and/or filling of the land surface to a desired slope or elevation. Illicit Discharge-Any discharge to a municipal separate storm sewer that is not composed entirely of storm water except discharges pursuant to.a NPDES permit (other than the NPDES permit for_discharges form the municipal separate storm sewer) and discharges resulting from fire fighting activities. MEP-MEP is the acronym for Maximum Extent Practicable.MEP is the technology- based standard established by Congress in CWA section 402(p)(3)(B)(iii)that municipal dischargers of storm water(MS4s)must meet.Technology-based standards establish the level of pollutant reductions that dischargers must achieve,typically by treatment or by a combination of treatment and best management practices (BMPs). MEP generally emphasizes pollution prevention and source control BMPs primarily (as the first line of defense)in combination with treatment methods serving as a backup (additional line of defense).MEP considers economics and is generally,but not necessarily,less stringent than BAT.A definition for MEP is not provided either in cc A-2 R.M0690•Huntington BeaMZOSOVMMP.MP0%7PR0JMC%.T8skW&det PtR09Wsseryd'aA updatOdAm Appendix A Glossary the statute or in the regulations.Instead the definition of MEP is dynamic and will be defined by the following process over time:municipalities propose'their definition of MEP by way of their Urban Runoff Management Plan.Their total collective and individual activities conducted pursuant to the Urban Runoff Management Plan becomes their proposal for MEP. Municipal Storm Water Conveyance System-(See Municipal Separate Storm Sewer System or MS4). Municipal Separate Storm Sewer System(MS4)-MS4 is an acronym for Municipal Separate Storm Sewer System A Municipal Separate Storm Sewer System is a conveyance or system of conveyances(including roads with drainage systems, municipal streets,catch basins,curbs,gutters,ditches,natural drainage features or channels,modified natural channels,man-made channels,or storm drains): (i)Owned or operated by a State,city town,borough,county,parish,district,association,or other public body (created by or pursuant to State law)having jurisdiction over disposal of sewage,industrial wastes,storm water,or other wastes,including special districts under State law such as a sewer district,flood control district or drainage district,or similar entity,or an Indian tribe or an authorized Indian tribal organization,or designated and approved management agency under section 208 of the CWA that discharges to waters of the United States; (ii)Designated or used for collecting of conveying storm water;(iii)Which is not a combined sewer; (iv) Which is not part of the Publicly Owned Treatment Works.(POTW)as defined at 40 CFR 122.2. Historic and current development make use of natural drainage patterns and features as conveyances for urban runoff.Urban streams used in this manner are part of the municipalities MS4 regardless of whether they are natural,man-made,or partially modified features.In these cases,the urban stream is both an MS4 and receiving water. National Pollution Discharge Elimination System,(NPDES)-These permits pertain to the discharge of waste to surface waters only.All State and Federal NPDES permits are also WDRs. Non Point Source (NPS)-Non point source refers to diffuse,widespread sources of pollution.These sources may be large or small,but are generally numerous throughout a watershed.Non Point Sources include but are not limited to urban, agricultural,or industrial areas,roads,highways,construction sites,communities served by septic systems,recreational boating activities,timber harvesting,mining, livestock grazing,as well as physical changes to stream channels,and habitat degradation.NPS pollution can occur year round any time rainfall,snowmelt, irrigation,or any other source of water runs over land or through the ground,picks up pollutants from these numerous,diffuse sources and deposits them into rivers, lakes, and coastal waters or introduces them into ground water. Non-Storm Water-Non-storm water consists of all discharges to and from a storm water conveyance system that do not originate from precipitation events (i.e.,all am A-3 PA10690-FlunOnpton 5each%W80.WQW-MPDpPROJDOCWTaskGWaster PleMplossarydmft updated.dx Appendix A Glossary discharges from a conveyance system other than storm water). Non-storm water includes illicit discharges,non-prohibited discharges,and NPDES permitted discharges. An illicit discharge is defined at 40 CFR 122.26(b) (2) as any discharge to a municipal storm water conveyance system.that is not composed entirely of storm water except discharges pursuant to a separate NPDES permit and discharges resulting from emergency fire fighting activities. Numeric effluent limitations-The typical method by which effluent limits are prescribed for pollutants in waste discharge requirements implementing the federal NPDES regulations.When numeric effluent limits are met at the"end-of-pipe",the effluent discharge generally will not cause water quality standards to be exceeded in the receiving waters (i.e.,water quality standards will also be met). Pollution-As defined in the Porter-Cologne Water Quality Control Act,pollution is "the alteration of the quality of the waters of the State by waste,to a degree that unreasonably affects the either of the following:A)The waters for beneficial uses;or B) Facilities that serve these beneficial uses." Pollution may include contamination. Pollutant-A pollutant is broadly defined as any agent that may cause or contribute to the degradation of water quality such that a condition of pollution or contamination is created or aggravated. Pollution Prevention-Pollution prevention is defined as practices and processes that reduce or eliminate the generation of pollutants,in contrast to source control, treatment,or disposal. Post-Construction BMPs-A subset of BMPs including structural and non-structural controls which detain,retain,filter,or educate to prevent the release of pollutants to surface waters during the final functional life of development. Sediment-Soil,sand,and minerals washed from land into water.Sediment resulting from anthropogenic sources(i.e.human induced land disturbance activities)is considered a pollutant. This Order regulates only the discharges of sediment from anthropogenic sources and does not regulate naturally occurring sources of sediment. Sediment can destroy fish-nesting areas,clog animal habitats,and cloud waters so that sunlight does not reach aquatic plants. Storm Water-"Storm water" is defined as urban runoff and snowmelt runoff consisting only of those discharges which originate from precipitation events.Storm water is that portion of precipitation that flows across a surface to the storm drain. system or receiving waters.Examples of this phenomenon include:the water that flows off a building's roof when it rains(runoff from an impervious surface);the water that flows into streams when snow on the ground begins to melt(runoff from a semi-pervious surface);and the water that flows from a vegetated surface when rainfall is in excess of the rate at which it can infiltrate into the underlying soil(runoff from a pervious surface).When all factors are equal,runoff increases as the perviousness of a surface decreases.During precipitation events in urban areas,rain CM A-4 PA10090.HunOnglon Beach%34WO-VA]MP.MP0VPR0JD0VB.Task9VAester Planiglassarydraft Wfted.doo Appendix A Glossary water picks up and transports pollutants through storm water conveyance systems, and ultimately to waters of the United States. Toxicity-Adverse responses of organisms to chemicals or physical agents ranging from mortality to physiological responses such as impaired reproduction or growth anomalies. The water quality objectives for toxicity provided in the Water Quality Control Plan,Santa Ana Region 8,(Basin Plan),state in part..."All waters shall be free of toxic substances in concentrations that are toxic to,or that produce detrimental physiological responses in human,plant,animal,or aquatic life....The survival of aquatic life in surface waters subjected to a waste discharge or other controllable water quality factors,shall not be less than that for the same water body in areas unaffected by the waste discharge"....Urban runoff discharges from MS4s are considered toxic when(1) the toxic effect observed in an acute toxicity test exceeds zero Toxic Units Acute (Tua=0);or(2)the toxic effect observed in a chronic toxicity test exceeds one Toxic Unit Chronic(Tuc=1).Urban runoff discharges from MS4s often contain pollutants that cause toxicity. Total Maximum Daily Load(TMDL)-The TMDL is the maximum amount of a pollutant that can be discharged into a water body from all sources (point and non- point) and still maintain water quality standards.Under Clean Water Act section 303(d),TMDLs must be developed for all water bodies that do not meet water quality standards after application of technology-based controls. Urban Runoff-Urban runoff is defined as all flows in a storm water conveyance system and consists of the following components: (1) storm water(wet weather flows) and (2)non-storm water illicit discharges(dry weather flows). Water Quality Objective-Numerical or narrative limits on constituents or characteristics of water designated to protect designated beneficial uses of the water. [California Water Code Section 13050(h)].California s water quality objectives are established by the State and Regional Water Boards in the Water Quality Control Plans.As stated in the Porter-Cologne Requirements for discharge (CWC 13263): "(Waste discharge) requirements shall implement any relevant water quality control plans that have been adopted,and shall take into consideration the beneficial uses to be protected,the.water objectives reasonably required for that purpose,other waste discharges,the need to prevent nuisance,and the provisions of Section 13241." Numeric or narrative limits for pollutants or characteristics of water designed to protect the beneficial uses of the water.In other words,a water quality objective is the maximum concentration of a pollutant that can exist in a receiving water and still generally ensure that the beneficial uses of the receiving water remain protected (i.e., not impaired).Since water quality objectives are designed specifically to protect the beneficial uses,when the objectives are violated the beneficial uses are,by definition, no longer protected and become impaired.This is a fundamental concept under the Porter Cologne Act.Equally fundamental is Porter Cologne's definition of pollution. A condition of pollution exists when the water quality needed to support designated beneficial uses has become unreasonably affected or impaired;in other words,when cm A-5 P:10890.Hun&oon 9eechW88o-VYQMP•MPO\7PROJDOCIB.TeskG\Masler Planblosserydmft updded.doe Appendix A Glossary the water quality objectives have been violated.These underlying definitions (regarding beneficial use protection)are the reason why all waste discharge requirements implementing the federal NPDES regulations require compliance with water quality objectives. (Water quality objectives are also called water quality criteria in the Clean_Water Act.). Water Quality Standards-are defined as the beneficial uses (e.g.,swimming,fishing, municipal drinking water supply,etc.,)of water and the water quality objectives necessary to protect those uses. Waters of the State-Any water,surface or underground,including saline waters within the boundaries of the State [California Water Code Section 13050 (e)].The definition of the Waters of the State is broader than that for the Waters of the United States in that all water in the State is considered to be a Waters of the State regardless of circumstances or condition. Waters of the United States-Waters of the United States can be broadly defined as navigable surface waters and all tributary surface waters to navigable surface waters. Groundwater is not considered to be a Waters of the United States. As defined in the 40 CFR 122.2,the Waters of the U.S. are defined as: "(a) All waters, which are currently used,were used in the past,or maybe susceptible to use in interstate or foreign commerce,including all waters.which are subject to the ebb and flow of the tide;.(b)All interstate waters,including interstate"wetlands;"(c)All other waters such as intrastate lakes,rivers,streams (including intermittent streams), mudflats,sandflats,"wetlands;' sloughs,prairie potholes,wet meadows,playa lakes, or natural ponds the use,degradation or destruction of which would affect or could affect interstate or foreign commerce including any such waters: (1) Which are or could be used by interstate or foreign travelers for recreational or other purposes; (2) From which fish or shellfish are or could be taken and sold in interstate or foreign commerce;or(3)Which are used or could be used for industrial purposes by industries in interstate commerce; (d)All impoundments of waters otherwise defined as waters of the United States under this definition: (e)Tributaries of waters identified in paragraphs (a)through(d) of this definition,(f)The territorial seas;and(g) "Wetlands" adjacent to waters (other than waters that are themselves wetlands) identified in paragraphs(a)through(f)of this definition.Waters of the United States do not include prior converted cropland.Notwithstanding the determination of-an area's status as prior converted cropland by any other federal agency,for the purposes of the Clean Water Act,the final authority regarding Clean Water Act jurisdiction remains with the EPA." Watershed-That geographical area which drains to a specified point on a water course,usually a confluence of streams or rivers (also known as drainage area, catchment,or river basin). CM .
