In order to meet the requirements for medium and high priority facilities,the owners/operators must select,install and maintain appropriate BMPs on site. Since the selection of the appropriate BMPs is a site-specific process,the types and numbers of additional BMPs will vary for each facility. 1. Prevent algae problems with regular cleaning,consistent adequate chlorine levels,and well- maintained water filtration and circulation systems. • Do not use copper-based algaecides. • Control algae with chlorine or other alternatives,such as sodium bromide. 2. Manage pH and water hardness to minimize corrosion of copper pipes. 3. Discharge pool and fountain water properly.Consider hiring a professional pool-draining service to collect all pool water for off-site disposal. If this is not feasible,adhere to the following: • When draining pools or fountains never discharge water to a street or storm drain,discharge to the sanitary sewer if permitted to do so. • If draining a pool to the sanitary sewer,prevent backflow by maintaining an"air gap"between the discharge line and the sewer line(do not seal the connection between the hose and sewer line). Be sure to call the local sewer authority for guidance on flow rate restrictions, backflow prevention,and handling special cleaning waste(such as acid wash). Keep discharge flows to the low levels. Higher flow rates may be prohibited by local ordinance. EPA"Preliminary Data Summary of Urban Stormwater Best Management Practices" IC16 Pool and Fountain Cleaning 1 • If water is dechlroinated with a neutralizing chemical or by allowing chlorine to dissipate for a few days(do not use the facility during this time),the water may be recycled/reused by -- draining it gradually onto a landscaped area. Water must be tested prior to discharge to ensure that chlorine is not present. • Provide drip pans or buckets beneath drain pipe connections to catch leaks. This will be especially pertinent if pool or spa water that has not been dechlorinated is pumped through piping to a discharge location. 4. Properly clean and/or dispose of filters. • Never clean a filter in the street or near a storm drain. • Rinse cartridge filters onto a dirt area,and work filter residue into soil. • Backwash diatomaceous earth filters onto dirt. Dispose of spent diatomaceous earth in the garbage. Diatomaceous earth cannot be discharged to surface waters,storm drainage systems,septic systems,or on the ground. • If there is not a suitable dirt area,discharge filter backwash or rinsewater to the sanitary sewer if permitted to do so by the local sewering agency. Training 1. Train employees on these BMPs,storm water discharge prohibitions,and wastewater discharge requirements. 2. Train employees on proper spill containment and cleanup. • Establish training that provides employees with the proper tools and knowledge to immediately begin cleaning up a spill. • Ensure that employees are familiar with the site's spill control plan and/or proper spill cleanup procedures. • BMP IC17 discusses Spill Prevention and Control in detail. 3. Train maintenance personnel on the proper techniques for testing chlorine levels and applying neutralizing chemicals. 4. Establish a regular training schedule,train all new employees,and conduct annual refresher training. 5. Use a training log or similar method to document training. Stencil storm drains Storm drain system signs act as highly visible source controls that are typically stenciled directly adjacent to storm drain inlets.

In order to meet the requirements for medium and high priority facilities,the owners/operators must select,install and maintain appropriate BMPs on site. Since the selection of the appropriate BMPs is a site-specific process,the types and numbers of additional BMPs will vary for each facility. Spill Prevention 1. Develop procedures to prevent/mitigate spills to storm drain systems. Standardize reporting procedures,containment,storage,and disposal activities,documentation,and follow-up procedures. 2. Post"No Dumping"signs with a phone number for reporting illegal dumping and disposal. 3. Conduct routine cleaning,inspections,and maintenance • Sweep and clean storage areas consistently at a designated frequency(e.g.weekly,monthly). DO NOT hose down areas to storm drains. • Place drip pans or absorbent materials beneath all mounted taps,and at all potential drip and spill locations during filling and unloading of tanks. Reuse,recycle,or properly dispose of any collected liquids or soiled absorbent materials. • Check tanks(and any containment sumps)frequently for leaks and spills. Replace tanks that are leaking,corroded,or otherwise deteriorating with tanks in good condition. Collect all spilled liquids and properly dispose of them. EPA"Preliminary Data Summary of Urban Stormwater Best Management Practices" IC 17 Spill Prevention and Control I • Check for external corrosion of material containers,structural failures,spills and overfills due to operator error,failure of piping system,etc. • Inspect tank foundations,connections,coatings,and tank walls and piping system. -- 4. Properly store and handle chemical materials. • Designate a secure material storage area that is paved with Portland cement concrete,free of cracks and gaps,and impervious in order to contain leaks and spills. • Do not store chemicals,drums,or bagged materials directly on the ground. Place these items in secondary containers. • Keep chemicals in their original containers,if feasible. • Keep containers well labeled according to their contents(e.g.,solvent,gasoline). • Label hazardous substances regarding the potential hazard(corrosive,radioactive,flammable, explosive,poisonous). • Prominently display required labels on transported hazardous and toxic materials(per U S DOT regulations). 5. Utilize secondary containment systems for liquid materials. • Surround storage tanks with a berm or other secondary containment system. • Slope the area inside the berm to a drain. • Drain liquids to the sanitary sewer if available. DO NOT discharge wash waterto sanitary sewer until contacting the local sewer authority to find out if pretreatment is required • Pass accumulated stormwater in petroleum storage areas through an oil/water separator. • Use catch basin filtration inserts. 6. Protect materials stored outside from stormwater runon. Construct a berm around the perimeter of the material storage area to prevent the runon of uncontaminated stormwater from adjacent areas as well as runoff of stormwater from the material. 7. Secure drums stored in an area where unauthorized persons may gain access to prevent accidental spillage,pilferage,or any unauthorized use. Spill Control and Cleanup Activities 8. Identify key spill response personnel. 9. Adopt the Orange County Hazardous Materials Area Plano ran equivalent plan,which includes a set of planned responses to hazardous materials emergencies. The plan should include: • Description of the facility,owner and address,activities and chemicals present • Facility map • Notification and evacuation procedures • Cleanup instructions • Identification of responsible departments 10. Clean up leaks and spills immediately. • Place a stockpile of spill cleanup materials where they will be readily accessible(e.g.near storage and maintenance areas). • Utilize dry cleaning methods to clean up spills to minimize the use of water. Use a rag for small spills,a damp mop for general cleanup,and absorbent material for larger spills. If the spilled material is hazardous,then used cleanup materials are also hazardous and must be sent to a certified laundry(rags)or disposed of as hazardous waste. Physical methods for the cleanup of dry chemicals include the use brooms,shovels,sweepers,or plows. • Never hose down or bury dry material spills. Sweep up the material and dispose of properly. • Clean up chemical materials with absorbents,gels,and foams. Use adsorbent materials on small spills rather than hosing down the spill. Remove the adsorbent materials promptly and dispose of properly. • For larger spills,a private spill cleanup company or Hazmat team may be necessary. IC17 Spill Prevention and Control 2 11. Reporting 1. Report spills that pose an immediate threat to human health or the environment to local agencies,such as the fire department,and the Regional Water Quality Control Board. 2. Establish a system for tracldng incidents. The'system should be designed to identify the following: • Types and quantities(in some cases)of wastes • Patterns in time of occurrence(time of day/night,month,or year) • Mode of dumping(abandoned containers,"midnight dumping"from moving vehicles,direct dumping of materials,accidents/spills) • Responsible parties 3. Federal regulations require that any oil spill into a water body or onto an adjoining shoreline be reported to the National Response Center(NRC)at 800-424-8802(24 hour). Training 1. Educate employees about spill prevention and cleanup. • Establish training that provides employees with the proper tools and knowledge to immediately begin cleaning up a spill. • Educate employees on aboveground storage tank requirements. • Train all employees upon hiring and conduct annual refresher training. 2. Train employees responsible for aboveground storage tanks and liquid transfers on the Spill Prevention Control and Countermeasure Plan.

Integrating and incorporating appropriate landscape planning methodologies into the project design is the most effective action that can be done to minimize surface and groundwater contamination from stormwater. Approach Landscape planning should couple consideration of land suitability for urban uses with consideration of community goals and projected growth. Project plan designs should conserve natural areas to the extent possible,maximize natural water storage and infiltration opportunities,and protect slopes and channels. Suitable Applications Appropriate applications include residential,commercial and industrial areas planned for development or redevelopment. Design Considerations Design requirements for site design and landscapes planning should conform to applicable standards and specifications of agencies with jurisdiction and be consistent with applicable :- General Plan and Local Area Plan policies. a a January 2003 California Stormwater BMP Handbook i of 4 New Development and Redevelopment www.cabmphandbooks.com SD-10 Site Design & Landscape Planning Desianina New Installations -- Begin the development of a plan for the landscape unit with attention to the following general principles: ■ Formulate the plan on the basis of clearly_articulated community goals. Carefully identify conflicts and choices between retaining and protecting desired resources and community growth. ■ Map and assess land suitability for urban uses. Include the following landscape features in the assessment: wooded land, open unwooded land, steep slopes,erosion-prone soils, foundation suitability, soil suitability for waste disposal, aquifers, aquifer recharge areas, wetlands,floodplains, surface waters, agricultural lands,and various categories of urban land use. When appropriate,the assessment can highlight outstanding local or regional resources that the community determines should be protected(e.g.,a scenic area, recreational area,threatened species habitat,farmland,fish run). Mapping and assessment should recognize not only these resources but also additional areas needed for their sustenance. Proj ect plan designs should conserve natural areas to the extent possible, maximize natural water storage and infiltration opportunities, and protect slopes and channels. Conserve Natural Areas during Landscape Planning If applicable,the following items are required and must be implemented in the site layout during the subdivision design and approval process,consistent with applicable General Plan and Local Area Plan policies: ® Cluster development on least-sensitive portions of a site while leaving the remaining land in a natural undisturbed condition. ® Limit clearing and grading of native vegetation at a site to the minimum amount needed to build lots, allow access, and provide fire protection. ■ Maximize trees and other vegetation at each site by planting additional vegetation, clustering tree areas, and promoting the use of native and/or drought tolerant plants. ® Promote natural vegetation by using parking lot islands and other landscaped areas. ® Preserve riparian areas and wetlands. Maximize Natural Water Storage and Infiltration Opportunities Within the Landscape unit ■ Promote the conservation of forest cover. Building on land that is already deforested affects basin hydrology to a lesser extent than converting forested land. Loss of forest cover reduces interception storage, detention in the organic forest floor layer, and water losses by evapotranspiration,resulting in large peak runoff increases and either their negative effects or the expense of countering them with structural solutions. ® Maintain natural storage reservoirs and drainage corridors,including depressions, areas of permeable soils, swales, and intermittent streams. Develop and implement policies and 2 of 4 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Site Design & Landscape Planning s®®1 regulations to discourage the clearing,filling,and channelization of these features. Utilize them in drainage networks in preference to pipes,culverts, and engineered ditches. ■ Evaluating infiltration opportunities by referring to the stormwater management manual for the jurisdiction and pay particular attention to the selection criteria for avoiding groundwater contamination,poor soils, and hydrogeological conditions that cause these facilities to fail. If necessary,locate developments with large amounts of impervious surfaces or a potential to produce relatively contaminated runoff away from groundwater recharge areas. Protection of Slopes and Channels during Landscape Design ■ Convey runoff safely from the tops of slopes. ® Avoid disturbing steep or unstable slopes. ■ Avoid disturbing natural channels. ® Stabilize disturbed slopes as quickly as possible. ■ Vegetate slopes with native or drought tolerant vegetation. ■ Control and treat flows in landscaping and/or other controls prior to reaching existing natural drainage systems. ® Stabilize temporary and permanent channel crossings as quickly as possible,and ensure that increases in run-off velocity and frequency caused by the proj ect do not erode the channel. ■ Install energy dissipaters, such as riprap,at the outlets of new storm drains,culverts, conduits,or channels that enter unlined channels in accordance with applicable specifications to minimize erosion. Energy dissipaters shall be installed in such a way as to minimize impacts to receiving waters. ® Line on-site conveyance channels where appropriate,to reduce erosion caused by increased flow velocity due to increases in tributary impervious area. The first choice for linings should be grass or some other vegetative surface, since these materials not only reduce runoff velocities,but also provide water quality benefits from filtration and infiltration. If velocities in the channel are high enough to erode grass or other vegetative linings,riprap, concrete, soil cement, or geo-grid stabilization are other alternatives. ® Consider other design principles that are comparable and equally effective. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans(SUSMP,WQMP,etc.) define"redevelopment"in terms of amounts of additional impervious area,increases in gross floor area and/or exterior construction,and land disturbing activities with structural or impervious surfaces. The definition of"redevelopment' must be consulted to determine whether or not the requirements for new development apply to areas intended for redevelopment. If the definition applies,the steps outlined under"designing new installations" above should be followed. January 2003 California Stormwater BMP Handbook 3 of 4 New Development and Redevelopment www.cabmphandbooks.com SD-10 site Design & Landscape Planning Redevelopment may present significant opportunity to add features which had not previously been implemented. Examples include incorporation of depressions, areas of permeable soils, and swales in newly redeveloped areas. While some site constraints may exist due to the status of already existing infrastructure, opportunities should not be missed to maximize infiltration, slow runoff,reduce impervious areas,disconnect directly connected impervious areas.

Posting notices regarding discharge prohibitions at storm drain inlets can prevent waste dumping. Storm drain signs and stencils are highly visible source controls that are typically placed directly adjacent to storm drain inlets. Approach The stencil or affixed sign contains a brief statement that prohibits dumping of improper materials into the urban runoff conveyance system. Storm drain messages have become a popular method of alerting the public about the effects of and the prohibitions against waste disposal. Suitable Applications Stencils and signs alert the public to the destination of pollutants discharged to the storm drain. Signs are appropriate in residential, commercial, and industrial areas,as well as any other area where contributions or dumping to storm drains is likely. Design Considerations Storm drain message markers or placards are recommended at all storm drain inlets within the boundary of a development project. The marker should be placed in clear sight facing toward anyone approaching the inlet from either side. All storm drain inlet locations should be identified on the development site map. Designing New Installations The following methods should be considered for inclusion in the proj ect design and show on proj ect plans: ® Provide stenciling or labeling of all storm drain inlets and catch basins,constructed or modified,within the proj ect area with prohibitive language. Examples include"NO DUMPING LSL1:pit*i a�t?33tw'L1 t"s'rt.: January 2003 California Stormwater BMP Handbook 1 of 2 New Development and Redevelopment www.cabmphandbooks.com S®-13 Storm ®rain Signage —DRAINS TO OCEAN' and/or other graphical icons to discourage illegal dumping. -- ® Post signs with prohibitive language and/or graphical icons,which prohibit illegal dumping at public access points along channels and creeks within the project area. Note-Some local agencies have approved specific signage and/or storm drain message placards for use. Consult local agency stormwater staff to determine specific requirements for placard types and methods of application. Redeveloping Existing Installations Various jurisdictional stormwater management and mitigation plans(SUSMP,WQMP, etc.) define"redevelopment'in terms of amounts of additional impervious area,increases in gross floor area and/or exterior construction, and land disturbing activities with structural or impervious surfaces. If the project meets the definition of"redevelopment",then the requirements stated under" designing new installations"above should be included in all project design plans. Additional Information Maintenance Considerations ® Legibility of markers and signs should be maintained. If required by the agency with jurisdiction over the project,the owner/operator or homeowner's association should enter into a maintenance agreement with the agency or record a deed restriction upon the property title to maintain the legibility of placards or signs. Placement ® Signage on top of curbs tends to weather and fade. ® Signage on face of curbs tends to be worn by contact with vehicle tires and sweeper brooms. Supplemental Information Examples ■ Most MS4 programs have storm drain signage programs. Some MS4 programs will provide stencils, or arrange for volunteers to stencil storm drains as part of their outreach program.

Designing New Installations Areas for washing/steam cleaning should incorporate one of the following features: ® Be self-contained and/or covered with a roof or overhang ® Be equipped with a clarifier or other pretreatment facility o Have a proper connection to a sanitary sewer January 2003 California Stormwater BMP Handbook 1 of 2 New Development and Redevelopment www.cabmphandbooks.com S®-33 Vehicle Washing Areas e Include other features which are comparable and equally effective -- CAR WASH AREAS-Some jurisdictions' stormwater managementplans include vehicle- cleaning area source control design requirements for community car wash racks in complexes with a large number of dwelling units. In these cases,wash water from the areas may be directed to the sanitary sewer,to an engineered infiltration system, or to an equally effective alternative. Pre-treatment may also be required. Depending on the jurisdiction,developers may be directed to divert surface water runoff away from the exposed area around the wash pad(parking lot,storage areas), and wash pad itself to alternatives other than the sanitary sewer. Roofing maybe required for exposed wash pads. It is generally advisable to cover areas used for regular washing of vehicles,trucks, or equipment,surround them with a perimeter berm, and clearly mark them as a designated washing area. Sumps or drain lines can be installed to collect wash water,which may be treated for reuse or recycling,or for discharge to the sanitary sewer. Jurisdictions may require some form of pretreatment, such as a trap,for these areas.

Limitations ® As some of the manufactured filter systems function at higher flow rates and/or have larger media than found in flatbed filters,the former may not provide the same level of performance as standard sand filters. However,the level of treatment may still be satisfactory. • As with all filtration systems,use in catchments that have significant areas of non-stabilized soils can lead to premature clogging. J:Caiffornia Stormwater luafity Association January 2003 California Stormwater BMP Handbook 1 of 3 New Development and Redevelopment www.cabmphandbooks.com MP-40 Media Filter Design and Sizing Guidelines -- There are currently three manufacturers of stormwater filter systems. Filter System A:This system is similar in appearance to a slow-rate sand filter. However,the media is cellulose material treated to enhance its ability to remove hydrocarbons and other organic compounds. The media depth is 12 inches(30 cm). It operates at a very high rate, 20 gpm/ft2 at peak flows. Normal operating rates are much lower assuming that the stormwater covers the entire bed at flows less than the peak rate. The system uses vortex separation for pretreatment. As the media is intended to remove sediments(with attached pollutants)and organic compounds,it would not be expected to remove dissolved pollutants such as nutrients and metals unless they are complexed with the organic compounds that are removed. Filter System B: It uses a simple vertical filter consisting of 3 inch diameter, 30 inch high slotted plastic pipe wrapped with fabric. The standard fabric has nominal openings of 10 microns. The stormwater flows into the vertical filter pipes and out through an underdrain system. Several units are placed vertically at i foot intervals to give the desired capacity. Pretreatment is typically a dry extended detention basin,with a detention time of about 3o hours. Stormwater is retained in the basin by a bladder that is automatically inflated when rainfall begins. This action starts a timer which opens the bladder 3o hours later. The filter bay has an emptying time of 12 to 24 hours,or about 1 to 2 gpm/ft2 of filter area. This provides a total elapsed time of 42 to 54 hours. Given that the media is fabric,the system does not remove dissolved pollutants. It does remove pollutants attached to the sediment that is removed. Filter System C:The system use vertical cartridges in which stormwater enters radially to a center well within the filter unit,flowing downward to an underdrain system. Flow is controlled by a passive float valve system,which prevents water from passing through the cartridge until the water level in the vault rises to the top of the cartridge. Full use of the entire filter surface area and the volume of the cartridge is assured by a passive siphon mechanism as the water surface recedes below the top of the cartridge. A balance between hydrostatic forces assures a more or less equal flow potential across the vertical face of the filter surface. Hence,the filter surface receives suspended solids evenly. Absent the float valve and siphon systems,the amount of water treated over time per unit area in a vertical filter is not constant,decreasing with the filter height;furthermore,a filter would clog unevenly. Restriction of the flow using orifices ensures consistent hydraulic conductivity of the cartridge as a whole by allowing the orifice, rather than the media,whose hydraulic conductivity decreases over time,to control flow. The manufacturer offers several media used singly or in combination(dual-or multi-media). Total media thickness is about 7 inches. Some media, such as fabric and perlite,remove only suspended solids(with attached pollutants). Media that also remove dissolved include compost, zeolite,and iron-infused polymer. Pretreatment occurs in an upstream unit and/or the vault within which the cartridges are located. Water quality volume or flow rate(depending on the particular product)is determined by local governments or sized so that 85%of the annual runoff volume is treated. Construction/Inspection Considerations ® Inspect one or more times as necessary during the first wet season of operation to be certain that it is draining properly. 2 of 3 California Stormwater BMP Handbook January 2003 New Development and Redevelopment www.cabmphandbooks.com Media Filter MP-40 Performance The mechanisms of pollutant removal are essentially the same as with public domain filters(TC -40)if of a similar design. Whether removal of dissolved pollutants occurs depends on the media. Perlite and fabric do not remove dissolved pollutants,whereas for examples,zeolites, compost,activated carbon,and peat have this capability. As most manufactured filter systems function at higher flow rates and have larger media than found in flatbed filters,they may not provide the same level of performance as standard sand filters. However,the level of treatment may still be satisfactory. Siting Criteria There are no unique siting criteria. Additional Design Guidelines Follow guidelines provided by the manufacturer. Maintenance ■ Maintenance activities and frequencies are specific to each product. Annual maintenance is typical. ■ Manufactured filters,like standard filters(TC-40),require more frequent maintenance than most standard treatment systems like wet ponds and constructed wetlands,typically annually for most sites. ■ Pretreatment systems that may precede the filter unit should be maintained at a frequency specified for the particular process. Cost Manufacturers provide costs for the units including delivery. Installation costs are generally on the order of 50 to 1OO %of the manufacturer's costs. Cost Considerations ■ Filters are generally more expensive to maintain than swales,ponds, and basins. ■ The modularity of the manufactured systems allows the design engineer to closely match the capacity of the facility to the design storm, more so than with most other manufactured products.

The Ocean Begins at Your Front Door REQUEST FOR CITY COUNCIL ACTION MEETING DATE: 11/5/2007 DEPARTMENT ID NUMBER: PW 07-064 Analysis: On May 5, 2004, the Planning Commission approved Environmental Impact Report No. 02-001, Tentative Tract Map No. 16338, Conditional Use Permit No. 2002-020, Special Permit No. 2002-004, and Coastal Development Permit No. 2002-012 for the development of a 191,000 square foot mixed-use project with retail, office, restaurant, cultural, and entertainment uses, a 400 room, eight story hotel, spa and health club above two levels of subterranean parking. On June 7, 2004, the City Council approved the project on appeal. Since then, the hotel has been redesigned and reduced to approximately 165 rooms. On October 16, 2006, the City Council/Redevelopment Agency approved an Owner Participation Agreement (OPA) with Makar Properties, LLC. As part of the OPA, Makar agreed that they would develop, design, install and construct the Regional Treatment System. As required by the Conditions of Approval for Conditional Use Permit No. 2002-020, Special Permit No. 2002-004, and Coastal Development Permit No. 2002-012, the Water Quality Management Plan is being submitted for City Council approval which includes the installation of the Regional Treatment System. The WQMP being submitted for approval is for the Retail and Phase I of the Residential project. Prior to issuance of the Precise Grading Permits for each of the subsequent phases, the WQMP will need to be amended to reflect additional information for each of the phases. Public Works Commission Action: Not required. Strategic Plan Goal: Provide quality public services with the highest professional standards to meet community expectations and needs, assuring that the city is sufficiently staffed and equipped overall. Environmental Status: The action to approve the WQMP is exempt from the requirements of the California Environmental Quality Act pursuant to Section 16268(a). Attachmeq s): • ber No. D ptiw 1.

The City of Huntington Beach will be responsible for maintenance of all offsite public streets and public storm drains including the Smart Sponge vault located on First Street and be partially funded by the owner via establishment of a "Urban Runoff Treatment Trust Fund for the First Street watershed storm flows (per Condition of Approval 5b). Fully developed, impermeable surfaces will cover approximately 80% of the project area (22.2 acres). Permeable surfaces will cover approximately 20% of the project area (5.6 acres). These areas are shown in green in Section 6, Exhibit A. Daily generation of homeowner related trash and retail commercial shops are anticipated. On a weekly basis, such trash will be collected by each tenant (business/homeowner) and disposed of in designated trash enclosures located throughout the project site to be removed by the local, private waste management company for proper disposal to a central trash disposal facility offsite. All restaurants and shops located within the commercial area and providing food services will be required to route sewer drains from food preparation areas through a grease interceptor prior to entering the public sewer system. An indoor grease storage unit will also be provided. All food within the hotel portion of the site will be prepared in a below grade kitchen. Pollutants of Concern The potential stormwater or urban runoff pollutants reasonably expected to be associated with this project are: 1. Sediment. Driveways, parking areas, roads and roof-tops are expected to be common sources of sediment due to wear. 2. Organic Compounds. These compounds can be expected to be derived from automotive fluids, pesticides, and fertilizers. 3. Nutrients. Nutrients, including nitrogen, phosphorous, and other compounds can be anticipated to be generated by or founding organic litter, fertilizers, food waste, sewage and sediment.

Metals Potential sources of trace metals (copper, lead, cadmium, chromium, nickel and zinc) include motor vehicles, re-roofing and hardscape/construction materials, and chemicals. 5. Bacteria and viruses. Anticipated sources include animal excrement (found in areas where pets are often walked), sanitary sewer overflow, restaurant service (food disposal), outdoor dining area, and trash container handling areas. 6. Oil and Grease. Potential sources of oil and grease include motor vehicles. 7. Oxygen-Demanding Substances. Potential sources include biodegradable organic materials and various household chemicals, which deplete dissolved oxygen levels in water courses. 8. Pesticides. Sources of pesticides include household bug-spray, weed killers and other household sources. 9. Trash and Debris. These sources include common litter, biodegradable organic matter such as leaves, grass cuttings and food wastes from landscaped areas. The Standard Industrial Classification (SIC) Code for the hotel area is 7011. The SIC Code for the commercial/retail center includes, but is not limited to, the following: office buildings (6512), restaurants (5812), night clubs (5813), parking stations and garages (7521) and valet services (7212). This project is classified as a Priority Project, Categories 1, 2, 4 and 8 per the Countywide Orange County Storm Water Program. Therefore, treatment control BMPs are required to remove pollutants typically associated with urban runoff. MAKALLON ATLANTA HUNTINGTON BEACH,LLC Section II (f\c\wgmp\2198-22 D02-1k.doc) September 17,2007 Page 9 Water Quality Management Plan(WQMP) "PACIFIC CITY"—TENTATIVE TRACT MAP NO.16338 CONDITIONAL USE PERMIT NO.02-20;SPECIAL PERMIT NO.02-04 COASTAL DEVELOPMENT PERMIT NO.02-12 HUNTINGTON BEACH,CALIFORNIA Section III Site Description Pacific City is located in the City of Huntington Beach, at the intersection of First Street and Pacific Coast Highway (PCH). The project location is shown on the vicinity map, Exhibit B. The total project onsite area is approximately 27.8 acres (31.5 gross acres). The site is located within the Huntington Beach Oil Field operated by Chevron and several abandoned oil wells exist within the site. Although operation has ceased for many years, the former oil drilling activities at the site have resulted in alterations to the previous landform. The site is currently vacant. The commercial portion of the site is designated CV-F7-sp (Commercial Visitor — Max. 3.0 Floor Area Ration — Specific Plan Overlay) and General Plan Subarea 4C (PCH/Lake Street), and the residential portion of the site is RH-30-sp (High Density Residential - Max. 30 du/ac— Specific Plan Overlay) and General Plan Subarea 4I (Atlanta-First Street). The site resides within the northern/northwestern portion of the Peninsular Ranges Geomorphic Province of Southern California. This province is characterized by northwest-southeast trending faults, folds, and mountain ranges. During the tie from the Pliocene period to the Pleistocene period, activities on the Newport-Inglewood Fault combined with regional tectonic effects, climatic forces, and changes in sea level, have resulted in the formation of the underlying basement materials and structure that underlay and support the project site. The forces that have created the geomorphology of the project site and vicinity are still active today. Generally, the majority of the site is underlain by terrace and engineered fill, which are, in turn, underlain by terrace deposits. The northerly and easterly portions of the project site are underlain by consolidated terrace deposits, which consist of several characteristics. Deposit colors range from reddish-brown to brown and yellowish to grayish. These deposits are generally over-consolidated and are formed by inter-layered lenses of silty to clayey sands and clayey silt and silty clay, with some interbeds of gravel and cobbles. Soils on the project site are generally slightly moist to moist and dense to very dense. The southerly to southwest portion of the project site is underlain by a wedge of softer, less consolidated sediments that include alluvial and lagoonal deposits. Within the site, these materials are characterized by zones of brown to gray sandy clay to sandy silt and clayey sands to clayey silt with zones of silty and poorly graded sands. In addition, artificial fills are found in several areas of the site. These fills generally consist of silty sands, sandy silts, and silty clays. Engineered fills, consisting generally of silty sands to clayey sands, were found within the bottom of or near an area referred to as the "borrow pit" in the northwestern two-thirds of the project site. The borrow pit is the area from where approximately 200,000 cubic yards of materials were exported in 1999 for use a fill for the Hyatt Regency Resort project. The bottom of this pit was backfilled in August 2000 with approximately two feet of soil. Pre-construction, the proposed site is approximately 1% impervious and approximately 99% pervious. Post-construction, the proposed site will consist of approximately 80% impervious surface and 20% pervious surface. The project resides in the coastal zone and within the jurisdiction of the Santa Ana Region Water Quality Control Board (SARWQCB). The site is located in the Santa Ana River Basin, within the Talbert Watershed. The Talbert Valley Watershed District (TVWD) has an overall area of 7,855-acres and is comprised of multiple tributary areas that contribute urban run-off along existing drainage channels. Two main tributaries drain this MAKALLON ATLANTA HUNTINGTON BEACH,LLC Section III (t\c\wgmp\2198-22 D02-Ik.doc) September 17,2007 Page 10 Water Quality Management Plan(WQMP) "PACIFIC CITY"—TENTATIVE TRACT MAP NO.16338 CONDITIONAL USE PERMIT NO.02-20;SPECIAL PERMIT NO.02-04 COASTAL DEVELOPMENT PERMIT NO.02-12 HUNTINGTON BEACH,CALIFORNIA watershed: on the western side, the Talbert and Huntington Beach Channels drain through the Talbert Marsh prior to emptying into the Pacific Ocean. On the eastern side, the Greenville-Banning Channel empties into the Santa Ana River. The project site is located within the western side of the watershed. The site is generally lower in elevation than the surrounding properties and drains to the southeast to existing storm drain facilities that discharge directly onto the beach. Existing Drainage All onsite flows are currently directed via a graded ditch and as sheet flow to an inlet located at the southeastern end of the site. The discharge is conveyed to the existing 42-inch reinforced concrete pipe in Pacific View Avenue, through the Atlanta Stormwater Pump Station (ASWPS), and eventually into the Huntington Beach Channel (HB Channel D01). The site discharges approximately 67.0 cfs in a 100-year storm to the storm drain at Pacific Avenue. See Section 6, Exhibit C. Pre-Development Conditions Storm Event. On Site Area Y� � .. CAS 25 48.6 100 67.0 Proposed Drainage In the developed condition, the project area is proposed to be divided into two separate drainage areas with separate storm drain systems (See Section 6, Exhibit D). The intent will be to reduce runoff directed to the ASWPS. The"Predevelopment"drainage area of 34.6 acres, currently tributary to the ASWPS, will be reduced to 7.7 acres (Drainage Area"A'�. The result will be a reduction in 100-year storm flow of 67.0 CFS to 21.8 CFS to the ASWPS. The storm flows from drainage Area "B"will be diverted away from the ASWPS to the City's FSSDS. The estimated 100-year storm flows from Drainage Area "B"is approximately 85.2 CFS however, the addition of an underground detention basin will limit these flows to 20 CFS, as directed by the City Public Works Department. The proposed project storm drain system will improve the storm flow protection for the ASWPS drainage area. A summary of the proposed on-site discharges in the 25 and 100-year events is shown in the following table: Post-Development Conditions Storm lEvent Drain ge Aria"A" 13rainage ear 7 ?Acres 2fr �res CIFS HS � 25 16.7 66.1 100 21.8 85.2 MAKALLON ATLANTA HUNTINGTON BEACH,LLC Section III (f\c\wgmp\2198-22 D02-Ik.doc) September 17,2007 Page 11 Water Quality Management Plan(WQMP) "PACIFIC CITY"—TENTATIVE TRACT MAP NO.16338 CONDITIONAL USE PERMIT NO.02-20;SPECIAL PERMIT NO.02-04 COASTAL DEVELOPMENT PERMIT NO.02-12 HUNTINGTON BEACH,CALIFORNIA Storm Flows Drainage 'A" The existing storm drain system in Pacific View Avenue (pipe size is 42" RCP) was assigned a future allowable discharge of 34.4 CFS for a 25-year event. The discharge was limited here in order to reduce the volume conveyed to the Atlanta Pump Station.' In the post-developed condition, a maximum of approximately 21.8 CFS will be permitted to be discharged into the existing 42" RCP in Pacific View Avenue because it cannot flow to First Street without pumping. Therefore, the Project drainage area "A"has been sized appropriately to this discharge limit for estimates a discharge of 21.8 CFS for the 100-year event. The expected discharge to the ASWPS is well below the previously designed allowable discharge of 34.4 CFS. Storm Runoff from Drainage Area "A" will discharge to Talbert Channel and then to the Pacific Ocean at the southern limits of Huntington State Beach. Exhibits D and E refer. Drainage "B" In the developed condition, Area "B", currently being conveyed to the existing storm drain system in Pacific View Avenue, will no longer be discharged to the Atlanta Storm Water Pump Station. This area, in a 25-year storm, will generate approximately 66.1 CFS to First Street without flood routing. Flood routing through an underground detention basin is proposed in order to limit the discharge to 20 CFS, as required by the City of Huntington Beach First Street Storm Drain design. A volume of approximately 0.88 acre-feet is required for this attenuation. Exhibit D and E refer. A tabular representation of pipe flow storm pre and post-development discharges is summarized below: Summary of Pipe Flow Discharges Dfscharges'taF area % 3 % Area`I " r r FSf d - ASWPS (pre-development) total 67.0 in 100- ear event in both areas ASWPS (post-development) 21.8 0 First Street (pre-development) 0 0 First Street(post-development) 0 20 CFS max. for all storm events Existing on-site storm flows from both areas (approximately 67.0 CFS for the 100-year event) currently discharge to the existing 42" storm drain system in Pacific View Avenue. In the developed condition, only the northerly, easterly and southerly perimeter area shown as Drainage Area "A", shown in blue hatch region on Exhibit D. Approximately 21.8 CFS for the 100-year event will discharge to the existing 42" pipe located in Pacific View Avenue. On the same exhibit, Drainage Area "B" (shown as solid yellow) is proposed to limit its maximum discharge to 20 CFS in the 25-year storm event to the City storm drain in First Street. This results in a net reduction of 45.2 CFS or about 67% of the flow to ASWPS.

Exhibit E refers. Dry Weather Flows Dry weather flows from Drainage "B" will be conveyed west towards First Street. Prior to being diverted into the City's storm drain system the flows will be treated by a Stormfilter water quality treatment unit. The flows are then conveyed to the First Street Storm Drain and during the dry season (April 151h _ October 15th) diverted into the Orange County Sanitation District's 54" Sewer Line along Pacific Coast Highway. Dry weather flows in Drainage "A" will be conveyed through a Stormfilter unit prior to discharging east to the ASWPS. These flows are then conveyed to the sanitary sewer system. The Dry Weather Urban Runoff Discharge Permit and Operational Agreement have been included as Appendix C. First Flush First flush flows from Drainage "B" will be conveyed west towards First Street, into proposed Stormfilter and Smart Sponge Vaults prior to entering the First Street Storm Drain System. First flush flows from Drainage"A"will be conveyed east into a proposed Stormfilter and then conveyed to the ASWPS. Parking Structure Drainage The underground parking area will not be allowed to drain to the storm drain system. Any non- stormwater nuisance flows will be treated by an oil/water separator to remove vehicle related pollutants and pollutants characteristic of parking areas prior to discharging to the sanitary sewer. Pumps will be used to remove runoff from the underground parking area and directed into the sanitary sewer. 303(d) Water Bodies This project is located within the jurisdiction of the Santa Ana Regional Water Quality Control Board and within the Talbert/Greenville Banning Channel Watershed (County of Orange Watershed D) and ultimately discharges to the Pacific Ocean at Huntington Beach. The 2006 CWA 303(d) list indicates that Huntington State Beach Park is impaired for Enterococcus from Unknown Sources for 50 yards around the Magnolia drain. (The project site is approximately 1.7 miles to the northwest of the Magnolia drain). Huntington State Beach Park is also impaired for PCBs (Polychlorinated biphenyls), also from Unknown Sources. Huntington State Beach Park Total Maximum Daily Load (TMDL) standards for Enterococcus and PCBs are proposed to be completed in 2019. The site does not contain nor impact any `environmentally sensitive areas"as defined by the 2003 Orange County Drainage Area Management Plan (DAMP) and the Water Quality Control Plan for the Santa Ana Basin (Basin Plan).z Hydrologic Conditions of Concern Hydrologic Conditions of Concern for any development such as the proposed project may include potential water quality degradation; increased runoff volume and velocity; reduced infiltration; increased flow frequency, duration and peaks; and faster time to reach peak flow resulting from development. As a result of the project's development (i.e., the upstream development), it has been determined by the preliminary project hydrology and water quality analysis prepared by Hunsaker & Associates Irvine, Inc. (H&A) that neither a significant potential for erosive conditions nor alteration of habitat of the downstream streams and channels would occur to the ASWPS and Huntington Beach Channel. Z Based on information obtained from the project's Environmental Impact Report. MAKALLON ATLANTA HUNTINGTON BEACH,LLC Section III (f\c\wgmp\2198-22 D02-Ik.doc) September 17,2007 Page 13 Water Quality Management Plan(WQMP) "PACIFIC CITY"—TENTATIVE TRACT MAP NO.16338 CONDITIONAL USE PERMIT NO.02-20;SPECIAL PERMIT NO.02-04 COASTAL DEVELOPMENT PERMIT NO.02-12 HUNTINGTON BEACH,CALIFORNIA However, project does increase the amount of runoff to FSSDS. This existing drainage line serves the Downtown area and conveys runoff across PCH to the Pacific Ocean, where runoff discharges at South Beach via an open ditch. The downtown drainage area, consisting of 26.1 acres west of the project site, is approximately bounded by Orange Avenue/Atlanta Avenue to the north, First (Lake) Street to the east, PCH to the south, and Third Street to the west. The City of Huntington Beach has constructed a new (Alabama Street storm drain) system in First Street to provide improved flood control protection. The new system will provide flood control protection to the Alabama Street drainage area, located north of the project. Although some concern exists with the potential for beach sand erosion, this is partially mitigated in the developed condition through the use of the underground storage basin to reduce peak flows. This will be located northeast of the intersection of First Street and Pacific View Avenue. See section 6, Exhibit A for location. In H&A discussions with Orange County staff (who drafted the language for the latest Countywide Model WQMP jointly with representatives from all Orange County Cities), it has been determined that the "downstream channel" (referenced in Item No. 1 of Section 7.II-3.2.4 of the Model WQMP) refers to the direct discharge point of the subject project. The intent of said section of the Model WQMP is to identify projects that have direct discharges to fully natural or partially improved channels. The proposed project does not have direct discharges to fully natural or partially improved channels. Rather, the proposed project will discharge to existing, fully improved Huntington Beach Channel and FSSDS. Based on the information above and our consultation with the County of Orange, it is our opinion that Items 2 — 4 of Section 7.II-3.2.4 of the Model WQMP, which relate to preparation of a drainage report, field reconnaissance and computations for critical hydrologic conditions for the "downstream channel," do not apply to this project.

This section describes how each of these BMPs were developed and will be implemented for the proposed project. For those routine BMPs that are not applicable to this project, an explanation is included as to why that is the case. All BMPs indicated in this WQMP will be maintained in good and effective condition. Structural BMPs evaluated for this WQMP included: StormFilter° and Abtech Smart Sponge Plus Vaults° By means of recorded community CC&R's, the MRA and MCA shall establish requirements for (a) ownership/maintenance of and/or maintenance easements for community common areas in the project and (b) implementation of community pollution prevention on BMPs, including community awareness programs. This WQMP identifies Best Management Practices (BMPs) that will be used onsite to control predictable pollutant runoff, and identifies, at a minimum, the measures specified in the Countywide Water Quality Management Plan (WQMP) and NPDES Drainage Area Management Plan (DAMP), the assignment of long- term maintenance responsibilities, and the locations(s) of all structural BMPs. Routine Source Control BMPs are required to be incorporated in all new development and redevelopment projects unless not applicable. In the tables provided, all BMPs to be incorporated in the project are indicated. For those designated as not applicable, a brief reason why is stated. All source control BMPs listed for specific land use/type of project in the following Countywide Water Quality Management Plan tables have been discussed and considered for utilization to the extent that they are appropriate for the site and project. IVA Site Design BMPs The following table shows site design BMPs that are included in this project. A brief description of each BMP also follows: Table IV.1.

Park area larger than required. 1 Detention and retention areas incorporated into landscape design provide areas for retaining and detaining stormwater flows,resulting in lower runoff rates and reductions in volume due to limited infiltration and evaporation. Such Site Design BMPs may reduce the size of Treatment Control BMPs. 2 The"C Factor"is a representation of the ability of a surface to produce runoff.Surfaces that produce higher volumes of runoff are represented by higher C Factors. By incorporating more pervious,lower C Factor surfaces into a development,lower volumes of runoff will be produced. Lower volumes and rates of runoff translate directly to lowering treatment requirements. Directly connected impervious areas (DCIAs) will be reduced throughout the project in a variety of ways. Roof drainage, sidewalks and driveways will be directed to landscaped areas where feasible. Other landscaped areas, commercial planters, the pedestrian corridor, park areas, and open space are used to break up areas of imperviousness. Multi-story residential condominium units have been incorporated into the project design, increasing overall living space but reducing unit footprint and thus reducing impervious space. Project is reducing peak runoff through the use of the underground storage basin (located northeast of the intersection of First Street and Pacific View Avenue) to partially mitigate downstream erosion. Although no`natural" areas exist onsite, open space, parks and a pedestrian corridor are being provided that will serve to reduce impervious areas and thus reduce the project's C-Factor. IV.2 Source Control BMPs All source control BMPs listed for specific land use/type of project in the following Countywide Water Quality Management Plan tables have been discussed and considered for utilization to the extent that they are appropriate for the site and project.

Media Filter Media Filter(StormFilter) Filtration will be achieved through the use of a series of StormFilters in conjunction with a retention/detention system designed in-line with the storm drain system. The purpose of the retention/detention system is to detain the required amount of storm water to limit the discharge of Drainage Area B to 20 cfs. See Section 6, Exhibit D for a depiction of Drainage Area B. The StormFilter is a premier filtration system widely recognized as a versatile BMP for removing a variety MAKALLON ATLANTA HUNTINGTON BEACH,LLC Section IV (f\c\wgmp\2198-22 D02-Ik.doc) September 17,2007 Page 23 Water Quality Management Plan(WQMP) "PACIFIC CITY"—TENTATIVE TRACT MAP NO.16338 CONDITIONAL USE PERMIT NO.02-20;SPECIAL PERMIT NO.02-04 COASTAL DEVELOPMENT PERMIT NO.02-12 HUNTINGTON BEACH,CALIFORNIA of pollutants. The StormFilter cartridges are filled with an array of media, selected to treat specific pollutant loadings at each site. These site-specific media options give the StormFilter the ability to remove high levels of storm water pollutants such as sediments, oil and grease, soluble heavy metals, organics and soluble nutrients. The StormFilter is unique in its ability to meet current and future pollution challenges. No other system offers this degree of excellence and versatility. It is important to note the Contech's pollutant treatment claims are supported by independent third party testing and evaluation. For further details, refer to Section 6, Exhibit F or see http://www.contech-cpi.com/stormwater/13. The StormFilter units consists of multiple filter cartridges housed in a buried concrete vault that is installed offline from the storm drain system. Pollutant removal is primarily accomplished by percolating accumulated storm water through the filter cartridges. A typical unit consists of an inlet bay where floatables, oils, and surface scum are trapped; a filter bay for the cartridges; and an outlet bay. Water from the inlet bay ponds in the filter cartridge bay and infiltrates the filter media, after which the treated water moves into the outlet bay and into the storm drainage system. The unit's filter cartridges will be installed with an even mix of ZPG media (ie., Zeolite, Perlite and GAC) to treat the pollutants anticipated by this project's intended land use. Abtech Smart Sponge° Plus Vaults Two vaults lined with Abtech Ultra Urban Smart Sponge baffles will be used as a part of a treatment train to target the project's pollutants of concern. Smart Sponge Plus features a proprietary antimicrobial agent chemically and permanently bound to the Smart Sponge surface that targets Enterococcus, Fecal Coliform and Escherichia Coli. The Smart Sponge Vaults will be inspected at minimum, annually and should be serviced as needed to remove sediment and debris, according to expected debris accumulation. The sediment and debris can be quickly vacuumed out of the modules through the opening of the drain with conventional maintenance equipment. Smart Sponge° technology transforms liquid hydrocarbons into a stable solid. The handling and disposal of this solid waste is less expensive and less problematic than that of other plastic and organic solvents. which will leach and leak hydrocarbons back into the environment. Spent Smart Sponge material generated from the AbTech laboratories have been classified as a solid waste and are acceptable at Subtitle D Landfills. Design Criteria All onsite treatment systems are flow-based systems, and therefore, are sized by estimating the peak water quality flow rate associated with the design storm determined in accordance with the Drainage Area Management Plan. This concept proposes separate systems to treat the off-site area and the on-site area.

Area "A" will be an in-series system consisting of a 6'W x 121 pre-cast (10 cartridges) and an 8'W x 161 pre-cast (26 cartridges). These will handle the low-flow and first flush treatment requirement for this drainage. The Storm Water Quality Design Flow (SQDF) calculated for Area "B" is 3.99 cfs (C = 0.73, I = 0.2 in/hr; A = 27.35 acres). The StormFilter sizing for Area "B" will accommodate this flow rate. Area "B" will be serviced by a single unit 16.5'W x 44.251 cast-in-place (114 cartridges). This unit will handle the first flush only. Both of the on-site areas will have first flush and dry weather flows treated by the above systems. The first flush and dry weather flows will be treated and then discharged to the city storm drain system. Up to 1.2 cfs would be treated then returned to the storm drain system in Pacific View. The large drainage area would include the treatment of up to 3.8 cfs then returned to the storm drain in First Street. Nuisance/non-stormwater flows from the underground parking structure will not be allowed to drain into the storm drain system, but rather, will be treated with an oil/water separator to remove vehicle related pollutants and pollutants characteristic of parking areas prior to discharging to the sanitary sewer. Sump pumps will be used to remove runoff from the underground parking area. Treatment of Anticipated Pollutants StormFilter The selected BMPs are anticipated to provide treatment for the majority of the project's pollutants of concern. Impacts from pesticides, nutrients and bacteria/viruses will also be minimized using routine non-structural and structural BMPs, such as common area efficient irrigation, landscape/pesticide use management, fertilizer management and daily clean up of pet wastes and food wastes. �+Iecl a=Fii rNlP 4Q 011ltt+tM1$yof Concern " p StormFNter� Sediment High Organic Compounds J Medium Nutrients Medium MAKALLON ATLANTA HUNTINGTON BEACH,LLC Section IV (f\c\wgmp\2198-22 D02-Ik.doc) September 17,2007 Page 25 Water Quality Management Plan(WQMP) "PACIFIC CITY"—TENTATIVE TRACT MAP NO.16338 CONDITIONAL USE PERMIT NO.02-20;SPECIAL PERMIT NO.02-04 COASTAL DEVELOPMENT PERMIT NO.02-12 HUNTINGTON BEACH,CALIFORNIA bf �e �I� rMP.4® Pollutan Ott I1Cn 7 SonFiltef° Metals Low/Medium* Bacteria and Viruses Low* Oil and Grease High Oxygen Demanding Low* Substances Pesticides Low* Trash and Debris High * Pollutants not in bound forms.

AbTech has developed and patented a process to chemically bond the agent to the Smart Sponge substrate. There is no leaching or depletion of the agent as it destroys microbes on contact, avoiding any downstream toxicity issues. The antimicrobial portion of the agent interacts electromagnetically (polarization) with the microbes, rupturing the cell wall and inactivating the microbe. It neither introduces chemicals into the treated water nor produces toxic metabolites. The agent has been proven effective in applications against such microorganisms as: Aspergillus Niger, Trychophyton, Mentagrophytes, Penicillium Pinophilum, Chaetomium Globosum, Trichoderma Virens, Candida Albicans, Salmonella, Klebsiella Pneumoniae, Listeria Monocytogenes, Fecal Coliforms, Aureobadisium Pullulans, Enterococcus, Staphylococcus Aureus, Escherichia Coli, and Pseudomonas Aeruginosa The Smart Sponge Plus antimicrobial capability also performs as a fungi static, odor and mildew control, thus eliminating these problems in storm sewer systems. According to "Flow Qualifications for AbTech Stormwater Anti-microbial Treatment Unit" : For the media configuration submitted to treat the Downtown Huntington Beach storm quality flows, the Smart Sponge IV can effectively treat for bacteria at a flow rate of 0.475 cfs per linear foot. Applying that rate to 25 linear feet of media yields 0.475 cfs/ft x 25 ft = 11.88cfs < 11.76cfs. Stormfflter/Smart Sponge Plus Treatment Train As previously noted, the Area "B" Storm Water Quality Design Flow (SQDF) is 3.99cfs. The StormFilter/Smart Sponge Plus Treatment train will serve as an effective means to remove the pollutants of concern generated by the project's land use. The StormFilter system will remove the trash, debris, sediment, nutrients metals and larger particulates. This pretreated drainage then flows through the Smart Sponge Plus vaults and are treated for a wide range of bacteria as previously discussed. All new Smart Sponge Plus (SSP) systems will have a bypass system to direct dry weather nuisance flows to the sanitary sewer. SSPs will only be activated and utilized for 1" flush storms. Redirection for the onsite system will be controlled by telemetry. This system will be controlled by the City but maintained by the HOA.

The overflow operates when the media and collects in the center tube of the inflow rate is greater than the treatment cartridge, where the float in the cartridge is capacity of the filter cartridges. in a closed (downward) position. Water continues to pass through the filter media and into the cartridge's center tube. The air in the cartridge is displaced by the water and purged from beneath the filter hood through the one-way check valve located in the cap. Once the center tube is filled with water (approximately 18 inches deep), there is enough buoyant force on the float to open the float valve and allow the treated water in the center tube to flow into the under-drain manifold. This causes the check valve to close, initiating a siphon that draws polluted water throughout the full surface area and volume of the filter.

During the past six years,AbTech has dedicated itself to the stormwater market, developing solutions to address pollutants and bacterial contaminants in stormwater runoff. All AbTech products are based on patented polymer technologies branded Smart Sponge®. This technology is the only non-toxic,fully recyclable filtration system that destroys bacteria and absorbs hydrocarbons on contact. Regulations Why Treat Stormwater? Contaminated stormwater runoff, known as 'non-point source pollution', is a major source of contamination for lakes, streams, rivers, estuaries, coastal waters and even groundwater. Federal EPA considers this source of contamination so onerous that the federal Clean Water Act (CWA), National Pollutant Discharge Elimination System (NPDES) stormwater phase I and II permit structure, requires permitees to treat their stormwater before discharge and issues permits with specific effluent discharge requirements. Permittees include: • All municipalities and their MS4 (Municipal Separate Storm Sewer System) o Phase 1 > 100,000 population o Phase II > 10,000 population • Many industries f • Construction development and redevelopment NP These permits require every responsible party/permittee (municipality, industry or construction site)to treat all stormwater originating on their property and remove pollution , to the `maximum extent practicable' (MEP)to meet the discharge standards of their permit. Of equal significance is the implementation of CWA section 303d, "Total Maximum Daily Load" (TMDL). This requires the management of entire watersheds and pays considerable attention to stormwater runoff contamination adversely impacting the water quality of all receiving waters. Of R worker Fnserti'�a" atch baSmAnserttorair, particular note are the many watersheds that have to address and grease$r,`ash;debris and 3ertimrtt removal groin storm water,as it ell the TMDLs for bacteria contamination.

(See Picture 1 posted on URL http: cf ub.epa.gav f npdes jstormwater�menuo#burps jpost 7.c#m) Smart Sponge® AbTech's Smart Sponge is a proprietary combination of synthetic polymers with a unique molecular structure that are chemically selective to hydrocarbons. Smart Sponge fully encapsulates recovered oil (see Section 2), preventing absorbed oil from leaching. It is also capable of removing low levels of oil from water (see Figure 2, Hydrocarbon Removal Efficiency of Ultra-Urbane Filter (UUF) with Smart Sponge, averaging 84%, see Millsaps Report Section 3),thereby successfully removing sheen.

Through its proprietary process,AbTech creates a unique porous structure (see Picture 3)that allows selective removal of hydrocarbons while treating large amounts of storm runoff (see Table 4, runoff treatment efficiency using UUF, showing over 90% efficiency at 600 gpm,see also Hydroqual Report,section 3). .. `�tz71�i1lrExsi t fiicklic" ,C c »Fa' t i11) P 6(0 Y !f I� Picture 3-Smart Sponge magnified 1,000X to Table 4 show porosity Smart Sponge Key Features • Hydrophobic • Non-Leaching / Encapsulates • Oleophilic hydrocarbons • Chemically Selective • Highly Porous During the past four years, AbTech has developed a new technology combining the traditional Smart Sponge features with an antimicrobial agent creating a new media called Smart Sponge Plus. Smart Sponge Plus The antimicrobial agent (Organosilone quaternary amine) (See Figure 5) used in the Smart Sponge Plus has been proven effective for over 20 years in many other antimicrobial applications in different markets. AbTech has developed and patented a process to chemically bond the agent (see Section 4) to the Smart Sponge substrate. There is no leaching or E, , depletion of the agent as it destroys microbes on contact, avoiding any downstream toxicity issues. s t.`� . � w't toss 1ITMN. The antimicrobial portion of the agent interacts electromagnetically (polarization) with the microbes, rupturing the cell wall and inactivating the microbe. It neither introduces chemicals into the treated water nor produces toxic metabolites. The agent has been proven effective in Figure 5 applications against such microorganisms as: • Aspergillus Niger • Trychophyton • Candida Albicans • Aureobadisium Pullulans Mentagrophytes • Salmonella • Enterococcus • Penicillium Pinophilum • Klebsiella Pneumoniae • Staphylococcus Aureus • Chaetomium Globosum • Listeria Monocytogenes . Escherichia Coli • Trichoderma Virens • Fecal Coliforms • Pseudomonas Aeruginosa The Smart Sponge Plus antimicrobial capability also performs as a fungi static,odor and mildew control, thus eliminating these problems in storm sewer systems. Field Results Extensive field tests (see Table 6, City of Norwalk,see also Section 5;Table 7, City of Long Beach,see also Section 5; see Table 8, City of Norwalk,see also Crossman Report,Section 5) on the Smart Sponge Plus have shown that it consistently reduces bacteria levels in stormwater by up to 99%. The use of Smart Sponge Plus would allow municipalities to meet federal EPA and state regulatory standards for indicator bacteria concentrations in effluent. At unusually high bacteria concentrations (106+),Smart Sponge Plus, when combined with other Smart Sponge Plus applications or other aggressive Best Management practices (BMPs),should facilitate municipalities meeting their stormwater permit discharge water quality requirements. mo Source: City of Norwalk R Nal Location: Norwalk, CT Feb. 2006 Location: Long Beach, Source.

Metals x Bacteria x Oil&Grease Organics&Toxicants Pesticides Oxygen Demanding Provided below are specific procedures associated with each of the minimum BMPs along with procedures for additional BMPs that should be considered if this activity takes place at a facility located near a sensitive waterbody. In order to meet the requirements for medium and high priority facilities,the owners/operators must select,install and maintain appropriate BMPs on site. Since the selection of the appropriate BMPs is a site-specific process,the types and numbers of additional BMPs will vary for each facility. 1. Properly collect and dispose of water when pressure washing buildings,rooftops,and other large objects. • If pressure washing where the surrounding area is paved,use a water collection device that enables collection of wash water and associated solids. Use a sump pump,wet vacuum or similarly effective device to collect the runoff and loose materials. Dispose of the collected runoff and solids properly. • If pressure washing on a landscaped area(with or without soap),runoff must be dispersed as sheet flow as much as possible,rather than as a concentrated stream. The wash runoff must remain on the landscaping and not drain to pavement. 2. Properly prepare work area before conducting building maintenance. • Use ground or drop cloths underneath outdoor painting,scraping,and sandblasting work,and properly dispose of collected material daily. • Use a ground cloth or oversized tub for activities such as paint mixing and tool cleaning. 3. Properly clean and dispose of equipment and wastes used and generated during building maintenance. I EPA"Preliminary Data Summary of Urban Stormwater Best Management Practices" I0 Building Maintenance 1 • Clean paint brushes and tools covered with water-based paints in sinks connected to sanitary sewers or in portable containers that can be dumped into a sanitary sewer drain. Brushes and -- tools covered with non-water-based paints,finishes,or other materials must be cleaned in a manner that enables collection of used solvents(e.g.,paint thinner,turpentine,etc.)for recycling or proper disposal. • Properly dispose of wash water,sweepings,and sediments. • Properly store equipment,chemicals,and wastes. • Do not dump any toxic substance or liquid waste on the pavement,the ground,or toward a storm drain. OPTIONAL: • Recycle residual paints,solvents,lumber,and other materials to the maximum extent practicable 4. Employ soil erosion and stabilization techniques when exposing large areas of soil. • Confine excavated materials to pervious surfaces away from storm drain inlets,sidewalks, pavement,and ditches. Material must be covered if rain is expected. • Use chemical stabilization or geosynthetics to stabilize bare ground surfaces. 5. Store toxic material undercover when not in use and during precipitation events. 6. Properly dispose of fluids from air conditioning,cooling tower,and condensate drains. 7. Regularly inspect air emission control equipment underAQMD permit. 8. Switch to non-toxic chemicals for maintenance when possible. • If cleaning agents are used,select biodegradable products whenever feasible • Consider using a waterless and non-toxic chemical cleaning method forgraffiti removal(e.g. gels or spray compounds). 9. Use chemicals that can be recycled. • Buy recycled products to the maximum extent practicable Training 1. Train employees on these BMPs,storm water discharge prohibitions,and wastewater discharge requirements. 2. Train employees on proper spill containment and cleanup. • Establish training that provides employees with the proper tools and knowledge to immediately begin cleaning up a spill. • Ensure that employees are familiar with the site's spill control plan and/or proper spill cleanup procedures. • BMP IC17 discusses Spill Prevention and Control in detail. 3. Establish a regular training schedule,train all new employees,and conduct annual refresher training. 4. Use a training log or similar method to document training.

Sediment x Nutrients x Floatable Materials x Metals Bacteria x Oil&Grease Organics&Toxicants Pesticides x Oxygen Demanding x Provided below are specific procedures associated with each of the minimum BMPs along with procedures for additional BMPs that should be considered if this activity takes place at a facility located near a sensitive waterbody. In order to meet the requirements for medium and high priority facilities,the owners/operators must select,install and maintain appropriate BMPs on site. Since the selection of the appropriate BMPs is a site- specific process,the types and numbers of additional BMPs will vary for each facility. 1. Take steps to reduce landscape maintenance requirements. • Where feasible,retain and/or plant native vegetation with features that are determined to be beneficial. Native vegetation usually requires less maintenance than planting new vegetation. • When planting or replanting consider using low water use flowers,trees,shrubs,and groundcovers. • Consider alternative landscaping techniques such as naturescaping and xeriscaping. 2. Properly store and dispose of gardening wastes. • Dispose of grass clippings,leaves,sticks,or other collected vegetation as garbage at a permitted landfill or by composting. • Do not dispose of gardening wastes in streets,waterways,or storm drainage systems. • Place temporarily stockpiled material away from watercourses and storm drain inlets,and berm and/orcover. 3. Use mulch or other erosion control measures on exposed soils. 1 EPA"Preliminary Data Summary of Urban Stormwater Best Managem ent Practices" IC7 Landscape Maintenance l 4. Properly manage irrigation and runoff. • Irrigate slowly or pulse irrigate so the infiltration rate of the soil is not exceeded. -- • Inspect irrigation system regularly for leaks and to ensure that excessive runoff is not occurring. • If re-claimed water is used for irrigation,ensure that there is no runoff from the landscaped area(s). • If bailing of muddy water is required(e.g.when repairing a water line leak),do not put it in the storm drain;pour over landscaped areas, • Use automatic timers to minimize runoff. • Use popup sprinkler heads in areas with a lot of activity or where pipes may be broken. Consider the use of mechanisms that reduce water flow to broken sprinkler heads. 5. Properly store and dispose of chemicals. • Implement storage requirements for pesticide products with guidance from the local fire department and/or County Agricultural Commissioner. • Provide secondary containment for chemical storage. • Dispose of empty containers according to the instructions on the container label. • Triple rinse containers and use rinse water as product. 6. Properly manage pesticide and herbicide use. • Follow all federal,state,and local laws and regulations governing the use,storage,and disposal of pesticides and herbicides and training of applicators and pest control advisors. • Follow manufacturers'recommendations and label directions. • Use pesticides only if there is an actual pest problem(not on a regular preventative schedule). When applicable use less toxic pesticides that will do the job. Avoid use of copper-based pesticides if possible. Use the minimum amount of chemicals needed for the job. • Do not apply pesticides if rain is expected or if wind speeds are above 5 mph. • Do not mix or prepare pesticides for application near storm drains. Prepare the minimum amount of pesticide needed for the job and use the lowest rate that will effectively control the targeted pest. • Whenever possible,use mechanical methods of vegetation removal rather than applying herbicides. Use hand weeding where practical. • Do not apply any chemicals directly to surface waters,unless the application is approved and permitted by the state. Do not spray pesticides within 100 feet of open waters. • Employ techniques to minimize off-target application(e.g.spray drift)of pesticides,including consideration of alternative application techniques. • When conducting mechanical or manual weed control,avoid loosening the soil,which could lead to erosion. • Purchase only the amount of pesticide that you can reasonably use in a given time period. • Careful soil mixing and layering techniques using a topsoil mix or composted organic material can be used as an effective measure to reduce herbicide use and watering. 7. Properly manage fertilizer use. • Follow all federal,state,and local laws and regulations governing the use,storage,and disposal of fertilizers. • Follow manufacturers'recommendations and label directions. • Employ techniques to minimize off-target application(e.g.spray drift)of fertilizer,including consideration of alternative application techniques. Calibrate fertilizer distributors to avoid excessive application. • Periodically test soils for determining proper fertilizer use. • Fertilizers should be worked into the soil rather than dumped or broadcast onto the surface. • Sweep pavement and sidewalk if fertilizer is spilled on these surfaces before applying irrigation water. • Use slow release fertilizers whenever possible to minimize leaching IC?Landscape Maintenance 2 8. Incorporate the following integrated pest management techniques where appropriate: • Mulching can be used to prevent weeds where turf is absent. • Remove insects by hand and place in soapy water or vegetable oil. Alternatively,remove insects with water or vacuum them off the plants. • Use species-specific traps(e.g.pheromone-based traps or colored sticky cards). • Sprinkle the ground surface with abrasive diatomaceous earth to prevent infestations by soft-bodied insects and slugs. Slugs also can be trapped in small cups filled with beer that are set in the ground so the slugs can get in easily. • In cases where microscopic parasites,such as bacteria and fungi,are causing damage to plants, the affected plant material can be removed and disposed of(pruning equipment should be disinfected with bleach to prevent spreading the disease organism). • Small mammals and birds can be excluded using fences,netting,and tree trunk guards. • Promote beneficial organisms,such as bats,birds,green lacewings,ladybugs,praying mantis, ground beetles,parasitic nematodes,trichogramma wasps,seedhead weevils,and spiders that prey on detrimental pest species. Training 1. Train employees on these BMPs,storm water discharge prohibitions,and wastewater discharge requirements. 2. Educate and train employees on the use of pesticides and pesticide application techniques. Only employees properly trained to use pesticides can apply them. 3. Train and encourage employees to use integrated pest management techniques. 4. Train employees on proper spill containment and cleanup. • Establish training that provides employees with the proper tools and knowledge to immediately begin cleaning up a spill. • Ensure that employees are familiar with the site's spill control plan and/or proper spill cleanup procedures. • BMP IC17 discusses Spill Prevention and Control in detail. 5. Establish a regular training schedule,train all new employees,and conduct annual refresher training. 6. Use a training log or similar method to document training.

Since the selection of the appropriate BMPs is a site-specific process,the types and numbers of additional BMPs will vary for each facility. I. Conduct regular cleaning. • Sweeping or vacuuming the parking facility is encouraged over other methods. • Sweep all parking lots at least once before the onset of the wet season. • Establish frequency of sweeping based on usage and field observations of waste accumulation. 2. Properly collect and dispose of wash water. • Block the storm drain or contain runoff. • Wash water should be collected and pumped to the sanitary sewer or discharged to a pervious surface,do not allow wash water to enter storm drains. DO NOT discharge wash water to sanitary sewer until contacting the local sewer authority to find out if pretreatment is required. • Dispose of parking lot sweeping debris and dirt at a landfill. 3. Consider use of source treatment BMPs to treat runoff. • Allow sheet runoff to flow into biofilters(vegetated strip and Swale)and/or infiltration devices. • Utilize sand filters or oleophilic collectors for oily waste in low quantities. 4. Keep the parking and storage areas clean and orderly. I EPA"Preliminary Data Summary of Urban Stormwater Best Management Practices" IC15 Parking Storage Area Maintenance 1 • Clean out and cover litter receptacles frequently to prevent spillage. • Remove debris in a timely fashion. -- OPTIONAL: • Post"No Littering"signs. 5. When cleaning heavy oily deposits: • If possible,clean oily spots with absorbent materials. • Do not allow discharges to the storm drain. • Appropriately dispose of spilled materials and absorbents. 6. When conducting surface repair work: • Pre-heat,transfer or load hot bituminous material away from storm drain inlets. • Conduct surface repair work during dry weather to prevent contamination from contacting stormwater runoff. • Cover and seal nearby storm drain inlets(with waterproof material or mesh)and manholes before applying seal coat,slurry seal,etc. Leave covers in place until job is complete and clean any debris for proper disposal. • To avoid runoff,use only as much water as necessary for dust control. • Use drip pans or absorbent material to catch drips from paving equipment that is not in use. Dispose of collected material and absorbents properly. 7. Conduct inspections on a regular basis. • Designate personnel to conduct inspections of the parking facilities and stormwater conveyance systems associated with them. • Inspect cleaning equipment/sweepers for leaks on a regular basis. 8. Keep accurate maintenance logs to evaluate materials removed/stored and improvements made. 9. Arrange rooftop drains to prevent drainage directly onto paved surfaces. Training 1. Train employees on these BMPs,storm water discharge prohibitions,and wastewater discharge requirements. 2. Train employees on proper spill containment and cleanup. • Establish training that provides employees with the proper tools and knowledge to immediately begin cleaning up a spill. • Ensure that employees are familiar with the site's spill control plan and/or proper spill cleanup procedures. • BMP IC17 discusses Spill Prevention and Control in detail. 3. Provide regulartraining to field employees and/or contractors regarding cleaning of paved areas and proper operation of equipment. 4. Establish a regular training schedule,train all new employees,and conduct annual refresher training. 5. Use a training log or similar method to document training.

Ten Ways that You Will Save the Most Ten ways that will save the most: ... ...... ... .......... ... . ..... ........... ......... .... ....... .... ............ Water your lawn only when it needs it. Step on your grass. If it springs back, A when you lift your foot, it doesn't need water. So set your sprinklers for more days �# in between watering. Saves 750-1,500 gallons per month. Better yet, especially in times of drought, water with a hose. 2. Fix leaky faucets and plumbing joints. Saves 20 gallons per day for every leak r stopped. 3. Don't run the hose while washing your car. Use a bucket of water and a quick hose rinse at the end. Saves 150 gallons each time. For a two-car family that's up 6 to 1,200 gallons a month. 4. Install water-saving shower heads or flow restrictors. Saves 500 to 800 gallons per month. 5. Run only full loads in the washing machine and dishwasher. Saves 300 to 800 gallons per month. 6. Shorten your showers. Even a one or two minute reduction can save up to 700 gallons per month. 7. Use a broom instead of a hose to clean driveways and sidewalks. Saves 150 gallons or more each time. At once a week, that's more than 600 gallons a month. 8. Don't use your toilet as an ashtray or wastebasket. Saves 400 to 600 gallons per month. 9. Capture tap water. While you wait for hot water to come down the pipes, catch the flow in a watering can to use later on house plants or your garden. Saves 200 to 300 gallons per month. 10. Don't water the sidewalks, driveway or gutter. Adjust your sprinklers so that water lands on your lawn or garden where it belongs-- and only there. Saves 500 gallons per month. 1 dMI �43rY6 Y W i' 6 4 In the bathroom: 1. Put a plastic bottle or a plastic bag weighted with pebbles and filled with water in your toilet tank. Displacing water in this manner allows you to use less water with each flush. Saves 5 to 10 gallons a day. That's up to 300 gallons a month, even more for large families. Better yet, for even greater savings, replace your water-guzzling five to seven gallon a flush toilet with a three and a half gallon, low flush, or one and a half gallon, ultra-low flush model. 2. If you're taking a shower, don't waste cold water while waiting for hot water to reach the shower head. Catch that water in a container to use on your outside plants or to flush your toilet. Saves 200 to 300 gallons a month. 3. Check toilet for leaks. Put dye tablets or food coloring into the tank. If color appears in the bowl without flushing, there's a leak that should be repaired. Saves 400 gallons a month. 4. Turn off the water while brushing your teeth. Saves three gallons each day. 5. Turn off the water while shaving. Fill the bottom of the sink with a few inches of water to rinse your razor. Saves three gallons each day. 2 In the kitchen and laundry: 1. If you wash dishes by hand--and that's the best way--don't leave the water running for rinsing. If you have two sinks, fill one with rinse water. If you only have one sink, use a spray device or short blasts instead of letting the water run. Saves 200 to 500 gallons a month. 2. When washing dishes by hand, use the least amount of detergent possible. This minimizes rinse water needed. Saves 50 to 150 gallons a month. 3. Keep a bottle of drinking water in the refrigerator. This beats the wasteful habit of running tap water to cool it for drinking. Saves 200 to 300 gallons a month. 4. Don't defrost frozen foods with running water. Either plan ahead by placing frozen items in the refrigerator overnight or defrost them in the microwave. Saves 50 to 150 gallons a month. °!5. Don't let the faucet run while you clean vegetables. Rinse them in a filled sink or pan. Saves 150 to 250 gallons a month. 6. Use the garbage disposal less and the garbage more (even better--compost!). Saves 50 to 150 gallons a month. 3 Outside: 1. Put a layer of mulch around trees and plants. Chunks of bark, peat moss or gravel slows down evaporation. Saves 750 to 1,500 gallons a month. 2. If you have a pool, use a pool cover to cut down on evaporation. It will also keep your pool cleaner and reduce the need to add chemicals. Saves 1,000 gallons a month. 3. Water during the cool parts of the day. Early morning is better than dusk since it helps prevent the growth of fungus. Saves 300 gallons. 4. Don't water the lawn on windy days. There's too much evaporation. Can waste up to 300 gallons in one watering. 5. Cut down watering on cool and overcast days and don't water in the rain. Adjust or deactivate automatic sprinklers. Can save up to 300 gallons each time. 6. Set lawn mower blades one notch higher. Longer grass means less evaporation. Saves 500 to 1,500 gallons each month. 7. Have an evaporative air conditioner? Direct the water drain line to a flower bed, tree base, or lawn. 8. Drive your car onto a lawn to wash it. Rinse water can help water the grass. 9. Tell your children not to play with the garden hose. Saves 10 gallons a minute. 10. If you allow your children to play in the sprinklers, make sure it's only when you're watering the yard--if it's not too cool at that time of day. 11. Xeriscape--replace your lawn and high-water-using trees and plants with less thirsty ones. But do this only in wet years. Even drought resistant plantings take extra water to get them going. That'll save 750 to 1,500 gallons a month. 12. When taking your car to a car wash--a good idea for saving water--be sure it's one of the many that recycles its wash water. 13. Dispose of hazardous materials properly! One quart of oil can contaminate 250,000 gallons of water, effectively eliminating that much water from our water supply. Contact your city or county for proper waste disposal options. 4 While Shopping Water is an essential ingredient in most manufacturing operations. Especially for those 1 billion of us in the high-consumption class, cutting down on our purchases of material things--from clothes and shoes to paper and appliances--conserves and protects water supplies as effectively as installing a low-flush toilet does. As with so many natural resources, as long as prices in the marketplace fail to reflect full social and ecological costs, voluntary changes in consumption patterns will play an important role in the quest for sustainability. • A kilogram (2.21bs) of hamburger or steak produced by a typical California beef cattle operation, for instance, uses some 20,500 liters (5,400 gal.) of water. • We rarely think about water when we see an automobile, for example, but producing a typical U.S. car requires more than 50 times its weight in water! • Producing 1 serving (4.3 oz.) of tomatoes requires 8 gallons of water. • Producing 1 serving (4.6 oz.) of oranges requires 14 gallons of water. • Producing 1 serving (2 oz.) of pasta requires 36 gallons of water. • Producing 1 serving (8 fl. oz.) of milk requires 48 gallons of water. • Producing 1 serving (8 oz.) of chicken requires 330 gallons of water. 5 3.
