The proposed project is considered a priority project because it is classified as a significant redevelopment project under the requirements listed in the Orange County Model WQMP table 7.II-2 row 8. A significant redevelopment project is described as one that adds or replaces 5,000 or more square feet of impervious surface. Water Quality Conditions Water Quality Conditions (list verbatim) There are no water quality conditions for this project. Watershed-Based Plan Conditions Provide applicable conditions from watershed - based plans including WIHMPs and TMDLS. A Watershed Infiltration and Hydro-modification Master Plan (WIHMP) has been developed and submitted for the San Diego Creek watershed, but has not yet been approved. See section III.3 for a list of TMDLs that have been established for San Diego Creak and Upper Newport Bay. Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section II Page 2 Section II - Project Description II.1 Project Description Description of Proposed Project Development Category (Verbatim from WQMP): New Mixed Use Development Project Area (ft2): 57,500 (1.32 Ac) Number of Dwelling Units: 21 condominium units SIC Code: 6513 Narrative Project Description: The project site is located on the east side of the intersection between Bonita Canyon Dr and MacArthur Blvd just west of Bonita Canyon Sports park. The existing 1.32-acre site is currently vacant land within City of Newport Beach and is zoned as a public facility. The proposed development will consist of a 21 unit condominium development and underground parking structure. The landscaping will include drought tolerant shrubs and trees in the interior and perimeter landscaping. The project shall include a pool, recreation rooms, courtyards, parking both inside the proposed parking structures and nearby the existing AT&T building to the east of the proposed development and trash enclosures. The project does not include outdoor materials storage areas, and equipment or vehicle maintenance, repair, outdoor food preparation areas, washing and fueling areas. Project Area Pervious Impervious Area (acres or sq ft) Percentage Area (acres or sq ft) Percentage Pre-Project Conditions 43,722 sq ft 76% 13,778 sq ft 24% Post-Project Conditions 17,825 sq ft 31% 39,675 sq ft 69% Drainage Patterns/Connections The existing site consists of relatively steep slopes that drain to the North east towards an existing storm drain structure located on the adjacent property to the North east. This existing storm drain within that North east site generally flows northly into larger storm drain pipes and channels (i.e. Bonita Channel OCFD F04) before discharging into the San Diego Creek Channel approximately a Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section II Page 3 mile North of the site. This channel eventually flows into upper Newport bay and ultimately discharges into the Pacific Ocean. The proposed drainage pattern is similar to the existing condition, except the proposed site will runoff into infiltration BMPs before discharging to their historic low points. Heavy flows shall overflow within the infiltration basins and discharge to the historic lowpoints onsite before following the existing drainage pattern and discharging to the north east towards the existing storm drain system. No new storm drain system is proposed at this time. For additional information on drainage patterns see the Hydrology Maps in section VI.1.

Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section II Page 5 II.3 Hydrologic Conditions of Concern No – Show map Yes – Describe applicable hydrologic conditions of concern below. Refer to Section 2.2.3 in the TGD. Based on Figure XVI-3a, Susceptibility Analysis Bonita Canyon Channel, This project is in the potential areas of erosion, habitat and physical structure susceptibility. The site drainage enters into Bonita Canyon Creek Channel and then flows into the San Diego Creek Channel approximately a mile North of the site. Because portions of San Diego Creek are not stabilized downstream from the site (i.e. earth channel without rip-rap), this creates a hydrologic condition of concern. Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section II Page 6 II.4 Post Development Drainage Characteristics Describe post development drainage characteristics. Refer to Section 2.2.4 in the TGD. The site is located in an area of low to moderate infiltration rates according to the Orange County Hydrology Map, which classifies the soil as being soil group C (infiltration rate approximately 0.25 in/hr). Due to the site being located in an area where there is not a storm drain system located in close proximity, bio retention BMPs with underdrains and an onsite storm drain system are not feasible. Therefore, for this project, infiltration BMPs are proposed. The proposed project drainage will be collected using roof downspouts, vegetated swales and concrete gutters which will allow the drainage to collect into the BMPs and infiltrate into the native soil approximately 3 feet below the finished grade. These bio treatment BMPs will consist of a layer of mulch (3”), and loosely compacted sandy loam soil media (36”). II.5 Property Ownership/Management Describe property ownership/management. Refer to Section 2.2.5 in the TGD. All parcels of the project are owned by Ford Holdings LP. No portions of the project will be transferred to a public agency and Ford Holdings LP will be responsible for long term maintenance of the projects stormwater facilities.

Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section IV Page 11 Section IV - Best Management Practices (BMPs) IV. 1 Project Performance Criteria (NOC Permit Area only) Is there an approved WIHMP or equivalent for the project area that includes more stringent LID feasibility criteria or if there are opportunities identified for implementing LID on regional or sub-regional basis? YES NO If yes, describe WIHMP feasibility criteria or regional/sub-regional LID opportunities. No Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section IV Page 12 Project Performance Criteria (continued) If HCOC exists, list applicable hydromodification control performance criteria (Section 7.II-2.4.2.2 in MWQMP) Based on Figure XVI-3a (Figure 4), Susceptibility Analysis Newport Bay Newport Coastal Streams, this project is in the potential areas of erosion, habitat and physical structure susceptibility. Because the imperviousness from the site will increase from 24% to 69%, the 2 year runoff volume from the site will be increased as shown below Existing Condition: Ve = C x d x A x 43560 sf/ac x 1/12 in/ft Ve = (0.90 x 0.24 + 0.15) x 2.05 x 1.32 x 43560 x 1/12 Ve = 3,595 CF Proposed Condition: Vp = C x d x A x 43560 sf/ac x 1/12 in/ft Vp = (0.90 x 0.69 + 0.15) x 2.05 x 1.32 x 43560 x 1/12 Vp = 7,573 CF Total Volume in BMPs: V = 3,959 CF (per table 1.1) Total Runoff from site: Vp=3,614 CF Net Difference: D V = 19 CF (0.5% increase) Therefore per the Orange County Technical Guidance Documents (OC TGD) there is no HCOC related to the runoff volume from the site. Next we shall analyze the change in time of concentration utilizing the Orange County approved RATSCx (AES) software. Full calculations can be found in Section VI and are summarized below. Subarea A: Existing Condition Tc = 5.91 min Proposed Condition Tc = 7.00 min (18.4% Increase) Subarea B: Existing Condition Tc = 6.08 min Proposed Condition Tc = 6.26 min (3.0% Increase) Per the OC TGD Section 5.3 Hydromodification should show that the Tc increase should be less than 5%. However, this increase is largely due to the implementation of LID BMPs. As mentioned in footnote 4 Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section IV Page 13 (referenced in Section 5.3) on page 2-8, for these conditions increases in Tc are acceptable and reductions in Tc of greater than 5 percent are not acceptable. Therefore, no HCOC exists related to Tc. Therefore, per the OC TGD no HCOC exists for this project and Hydromodification BMPs are not needed. List applicable LID performance criteria (Section 7.II-2.4.3 from MWQMP) 1) Priority Projects must infiltrate, harvest and use, evapotranspire, or biotreat/biofilter, the 85th percentile, 24-hour storm event (Design Capture Volume). 2) A properly designed biotreatment system may only be considered if infiltration, harvest and use, and evapotranspiration (ET) cannot be feasibly implemented for the full design capture volume. In this case, infiltration, harvest and use, and ET practices must be implemented to the greatest extent feasible and biotreatment may be provided for the remaining design capture volume. List applicable treatment control BMP performance criteria (Section 7.II-3.2.2 from MWQMP) For this project, no treatment control BMPs are being proposed. Because infiltration is feasible on this project, infiltration basins will be the primary storm water BMP used on the project. Calculate LID design storm capture volume for Project. See Table 1.1 included in section VI Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section IV Page 14 IV.2. SITE DESIGN AND DRAINAGE PLAN Describe site design and drainage plan including • A narrative of site design practices utilized or rationale for not using practices; • A narrative of how site is designed to allow BMPs to be incorporated to the MEP • A table of DMA characteristics and list of LID BMPs proposed in each DMA. • Reference to the WQMP plot plan. • Calculation of Design Capture Volume (DCV) for each drainage area. • A listing of GIS coordinates for LID and Treatment Control BMPs (unless not required by local jurisdiction). Refer to Section 2.4.2 in the TGD. The first step in the LID BMP selection process is to consider HSCs. There are no significant HSCs proposed for this project. The next step is to consider infiltration BMPs or harvest and use BMPs. Since the use of bioretention BMPs are adequate to fully retain the Design Storm Capture volume for the project, no other LID BMPs were used in the calculations. The site drainage is designed to allow the design capture volume to settle within the BMPs, and the peak flows to overflow to the historic low point located at the north end of the site. The attached map in Section VI (WQMP Drainage/Site Plan) describes the stormwater drainage management area (DMA) and proposed BMPs. The BMP Sizing Table 1.1 in Section VI includes the Design Capture Volume (DCV) calculations. GIS coordinates for the BMPs are as follows: Bioretention (Subarea A-1): N 2,176,353 E 6,071,231 Bioretention (Subarea A-2): N 2,176,346 E 6,071,323 Bioretention (Subarea A-3): N 2,176,165 E 6,071,301 Bioretention (Subarea A-4): N 2,176,219 E 6,071,408 Bioretention (Subarea A-5): N 2,176,121 E 6,071,419 Bioretention (Subarea A-6): N 2,176,300 E 6,071,437 Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section IV Page 15 IV.3 LID BMP SELECTION AND PROJECT CONFORMANCE ANALYSIS Each sub-section below documents that the proposed design features conform to the applicable project performance criteria via check boxes, tables, calculations, narratives, and/or references to worksheets. Refer to Section 2.4.2.3 in the TGD for selecting LID BMPs and Section 2.4.3 in the TGD for conducting conformance analysis with project performance criteria.

Name Included? Bioretention Rain gardens Porous landscaping Infiltration planters Retention swales Infiltration trenches Infiltration basins Drywells Subsurface infiltration galleries French drains Permeable asphalt Permeable concrete Permeable concrete pavers Other: Other: The predominant soil type is C, which typically has measured infiltration rates around 0.25”/hr which can be seen as low to moderate infiltration rates. However, due to the absence of an existing storm drain system within close proximity to the site infiltration seems to be the most feasible solution. Infiltration testing shall be done by the geotechnical engineer, Langan Engineering & Environmental Services, Inc to measure this site’s infiltration rates. The design infiltration rate is based on the typical measured infiltration rate for soil type C and shall be modified when further information becomes available. See Table 1.1 in Section VI for calculations.

The following methods have been implemented to reduce excessive irrigation runoff: • Employment of irrometer devices (moisture sensors) to prevent irrigation after precipitation. • The use of flow sensors and master control valves to shut down valve when triggered by a pressure drop. This shut down will control water loss in the event of broken sprinkler heads or lines. • The irrigation application method considered shall be a drip system. A drip irrigation system is buried under the soil, which eliminates runoff and wind misting and minimizes water loss due to evaporation. • The timing of irrigation water shall be designed at short repeat cycles to further eliminate irrigation water runoff and to minimize erosion, due to saturated soil. • Although no native or drought-tolerant plants will be used, the plants used have low to medium water requirements and are appropriate for the climate of the area. • Mulch is used in planter areas to minimize sediment in runoff. The procedures for irrigation system and landscape maintenance and inspection are described in Section V, Operations and Maintenance Plan (N3). The irrigation system shall be inspected weekly in conjunction with maintenance activities. Preliminary Water Quality Management Plan (WQMP) Ford Road Residential, 4302 Ford Road, Newport Beach, CA 92660 Hines Brea Place Acquisitions Partners, LLC Section IV Page 28 IV.4 ALTERNATIVE COMPLIANCE PLAN (IF APPLICABLE) IV.4.1 Water Quality Credits Description of Proposed Project Project Types that Qualify for Water Quality Credits (Select all that apply): Redevelopment projects that reduce the overall impervious footprint of the project site. Brownfield redevelopment, meaning redevelopment, expansion, or reuse of real property which may be complicated by the presence or potential presence of hazardous substances, pollutants or contaminants, and which have the potential to contribute to adverse ground or surface WQ if not redeveloped. Higher density development projects which include two distinct categories (credits can only be taken for one category): those with more than seven units per acre of development (lower credit allowance); vertical density developments, for example, those with a Floor to Area Ratio (FAR) of 2 or those having more than 18 units per acre (greater credit allowance). Mixed use development, such as a combination of residential, commercial, industrial, office, institutional, or other land uses which incorporate design principles that can demonstrate environmental benefits that would not be realized through single use projects (e.g. reduced vehicle trip traffic with the potential to reduce sources of water or air pollution). Transit-oriented developments, such as a mixed use residential or commercial area designed to maximize access to public transportation; similar to above criterion, but where the development center is within one half mile of a mass transit center (e.g. bus, rail, light rail or commuter train station). Such projects would not be able to take credit for both categories, but may have greater credit assigned Redevelopment projects in an established historic district, historic preservation area, or similar significant city area including core City Center areas (to be defined through mapping). Developments with dedication of undeveloped portions to parks, preservation areas and other pervious uses. Developments in a city center area. Developments in historic districts or historic preservation areas. Live-work developments, a variety of developments designed to support residential and vocational needs together – similar to criteria to mixed use development; would not be able to take credit for both categories. In-fill projects, the conversion of empty lots and other underused spaces into more beneficially used spaces, such as residential or commercial areas.

These facilities function as a soil and plant-based filtration device that removes pollutants through a variety of physical, biological, and chemical treatment processes. The facilities normally consist of a ponding area, mulch layer, planting soils, and plants. As stormwater passes down through the planting soil, pollutants are filtered, adsorbed, and biodegraded by the soil and plants. For areas with low permeability native soils or steep slopes, bioretention areas can be designed with an underdrain system that routes the treated runoff to the storm drain system rather than depending entirely on infiltration. Feasibility Screening Considerations  Bioretention with no underdrains shall pass infiltration infeasibility screening criteria to be considered for use. Opportunity Criteria  Land use may include commercial, residential, mixed use, institutional, and subdivisions. Bioretention may also be applied in parking lot islands, cul-de-sacs, traffic circles, road shoulders, and road medians.  Drainage area is ≤ 5 acres, preferrably ≤ 1 acre.  Area available for infiltration.  Soils are adequate for infiltration or can be amended to improve infiltration capacity. Site slope is less than 15 percent. OC-Specific Design Criteria and Considerations □ Placement of BMPs should observe geotechnical recommendations with respect to geological hazards (e.g. landslides, liquefaction zones, erosion, etc.) and set-backs (e.g., foundations, utilities, roadways, etc.) □ Depth to mounded seasonally high groundwater shall not be less than 5 feet. □ If sheet flow is conveyed to the treatment area over stabilized grassed areas, the site must be graded in such a way that minimizes erosive conditions; sheet flow velocities should not exceed 1 foot per second. □ Ponding depth should not exceed 18 inches; fencing may be required if ponding depth exceeds 6 inches to mitigate the risk of drowning. □ Planting/storage media shall be based on the recommendations contained in MISC-1: Planting/Storage Media □ The minimum amended soil depth is 1.5 feet (3 feet is preferred). □ The maximum drawdown time of the planting soil is 48 hours. Also known as:  Rain gardens  Infiltration planter Bioretention Source: Geosyntec Consultants TECHNICAL GUIDANCE DOCUMENT APPENDICES XIV-30 May 19, 2011 □ Infiltration pathways may need to be restricted due to the close proximity of roads, foundations, or other infrastructure. A geomembrane liner, or other equivalent water proofing, may be placed along the vertical walls to reduce lateral flows. This liner should have a minimum thickness of 30 mils. □ Plant materials should be tolerant of summer drought, ponding fluctuations, and saturated soil conditions for 48 hours; native plant species and/or hardy cultivars that are not invasive and do not require chemical fertilizers or pesticides should be used to the maximum extent feasible. □ The bioretention area should be covered with 2-4 inches (average 3 inches) of mulch at startup and an additional placement of 1-2 inches of mulch should be added annually. □ An optional gravel drainage layer may be installed below planting media to augment storage volume. □ An overflow device is required at the top of the ponding depth. □ Dispersed flow or energy dissipation (i.e. splash rocks) for piped inlets should be provided at basin inlet to prevent erosion. Simple Sizing Method for Bioretention with no Underdrain If the Simple Design Capture Volume Sizing Method described in Appendix III.3.1 is used to size a bioretention area with underdrains, the user calculates the DCV and designs the system with geometry required to draw down the DCV in 48 hours. The sizing steps are as follows: Step 1: Determine the Bioretention Design Capture Volume Calculate the DCV using the Simple Design Capture Volume Sizing Method described in Appendix III.3.1. Step 2: Determine the 48-hour Ponding Depth The depth of effective storage depth that can be drawn down in 48 hours can be calculated using the following equation: d48 = KDESIGN × 4 Where: d48 = bioretention 48-hour effective depth, ft KDESIGN = bioretention design infiltration rate, in/hr (See Appendix VII) This is the maximum effective depth of the basin below the overflow device to achieve drawdown in 48 hours. Effective depth includes ponding water and media/aggregate pore space. Step 3: Design System Geometry to Provide d48 Design system geometry such that d48 ≥ dEFFECTIVE = (dP + nMdM + nGdG) Where: d48 = depth of water that can drain in 48 hours dEFFECTIVE = total effective depth of water stored in bioretention area, ft dP = bioretention ponding depth, ft (should be less than or equal to 1.5 ft) nM = bioretention media porosity dM = bioretention media depth, ft TECHNICAL GUIDANCE DOCUMENT APPENDICES XIV-31 May 19, 2011 nG = bioretention gravel layer porosity; 0.35 may be assumed where other information is not available dG = bioretention gravel layer depth, ft Step 4: Calculate the Required Infiltrating Area The required infiltrating area (i.e. measured at the media surface) can be calculated using the following equation: A = DCV / dEFFECTIVE Where: A = required infiltrating area, sq-ft (measured as the media surface area) DCV = design capture volume, cu-ft (see Step 1) dEFFECTIVE = total effective depth of water stored in bioretention area, ft (from Step 3) This does not include the side slopes, access roads, etc. which would increase bioretention footprint. Capture Efficiency Method for Bioretention with no Underdrain If BMP geometry has already been defined and deviates from the 48 hour drawdown time, the designer can use the Capture Efficiency Method for Volume-Based, Constant Drawdown BMPs (See Appendix III.3.2) to determine the fraction of the DCV that must be provided to manage 80 percent of average annual runoff volume. This method accounts for drawdown time different than 48 hours. Step 1: Determine the drawdown time associated with the selected basin geometry DD = (dEFFECTIVE / KDESIGN) × 12 in/ft Where: DD = time to completely drain infiltration basin ponding depth, hours dEFFECTIVE ≤ (dP + nMdM + nGdG) dP = bioretention ponding depth, ft (should be less than or equal to 1.5 ft) nM = bioretention media porosity dM = bioretention media depth, ft nG = bioretention gravel layer porosity; 0.35 may be assumed where other information is not available dG = bioretention gravel layer depth, ft KDESIGN = basin design infiltration rate, in/hr (See Appendix VII) Step 2: Determine the Required Adjusted DCV for this Drawdown Time Use the Capture Efficiency Method for Volume-Based, Constant Drawdown BMPs (See Appendix III.3.2) to calculate the fraction of the DCV the basin must hold to achieve 80 percent capture of average annual stormwater runoff volume based on the basin drawdown time calculated above. Step 4: Check that the Bioretention Effective Depth Drains in no Greater than 96 Hours DD = (dEFFECTIVE / KDESIGN) × 12 Where: DD = time to completely drain bioretention facility, hours dEFFECTIVE = total effective depth of water stored in bioretention area, ft (from Step 3) KDESIGN = basin design infiltration rate, in/hr (See Appendix VII) TECHNICAL GUIDANCE DOCUMENT APPENDICES XIV-32 May 19, 2011 If DDALL is greater than 96 hours, adjust bioretention media depth and/or gravel layer depth until DD is less than 96 hours. This duration is based on preventing extended periods of saturation from causing plant mortality. Step 5: Determine the Basin Infiltrating Area Needed The required infiltrating area (i.e. the surface area of the top of the media layer) can be calculated using the following equation: A = DCV/ dEFFECTIVE Where: A = required infiltrating area, sq-ft (measured at the media surface) DCV = design capture volume, adjusted for drawdown time, cu-ft (see Step 1) dEFFECTIVE = total effective depth of water stored in bioretention area, ft (from Step 3) This does not include the side slopes, access roads, etc. which would increase bioretention footprint. If the area required is greater than the selected basin area, adjust surface area or adjust ponding depth and recalculate required area until the required area is achieved. Configuration for Use in a Treatment Train  Bioretention areas may be preceeded in a treatment train by HSCs in the drainage area, which would reduce the required volume of the bioretention cell.  Bioretention areas can be incorporated in a treatment train to provide enhanced water quality treatment and reductions in runoff volume and rate. For example, runoff can be collected from a roadway in a vegetated swale that then flows to a bioretention area. Similarly, bioretention could be used to manage overflow from a cistern.

Most people believe that the largest source of water pollution in urban areas comes from specific sources such as factories and sewage treatment plants In fact, the largest source of water pollution comes from city streets, neighborhoods, construction sites and parking lots This type of pollution is sometimes called “non-point source” pollution There are two types of non-point source pollution: stormwater and urban runoff pollution Stormwater runoff results from rainfall When rainstorms cause large volumes of water to rinse the urban landscape, picking up pollutants along the way Urban runoff can happen any time of the year when excessive water use from irrigation, vehicle washing and other sources carries trash, lawn clippings and other urban pollutants into storm drains Where Does It Go? Anything we use outside homes, vehicles and businesses – like motor oil, paint, pesticides, fertilizers and cleaners – can be blown or washed into storm drains A little water from a garden hose or rain can also send materials into storm drains Storm drains are separate from our sanitary sewer systems; unlike water in sanitary sewers (from sinks or toilets), water in storm drains is not treated before entering our waterways Printed on Recycled Paper The Orange County Stormwater Program has created and moderates an electronic mailing list to facilitate communications, take questions and exchange ideas among its users about issues and topics related to stormwater and urban runoff and the implementation of program elements To join the list, please send an email to ocstormwaterinfo-join@list ocwatersheds com Orange County Stormwater Program Even if you live miles from the Pacific Ocean, you may be unknowingly polluting it.Sources of Non-Point Source Pollution Automotive leaks and spills Improper disposal of used oil and other engine fluids Metals found in vehicle exhaust, weathered paint, rust, metal plating and tires Pesticides and fertilizers from lawns, gardens and farms Improper disposal of cleaners, paint and paint removers Soil erosion and dust debris from landscape and construction activities Litter, lawn clippings, animal waste, and other organic matter Oil stains on parking lots and paved surfaces The Effect on the OceanNon-point source pollution can have a serious impact on water quality in Orange County Pollutants from the storm drain system can harm marine life as well as coastal and wetland habitats They can also degrade recreation areas such as beaches, harbors and bays Stormwater quality management programs have been developed throughout Orange County to educate and encourage the public to protect water quality, monitor runoff in the storm drain system, investigate illegal dumping and maintain storm drains Support from Orange County residents and businesses is needed to improve water quality and reduce urban runoff pollution Proper use and disposal of materials will help stop pollution before it reaches the storm drain and the ocean Dumping one quart of motor oil into a storm drain can contaminate 250,000 gallons of water. Follow these simple steps to help reduce water pollution: Household Activities Do not rinse spills with water Use dry cleanup methods such as applying cat litter or another absorbent material, sweep and dispose of in the trash Take items such as used or excess batteries, oven cleaners, automotive fluids, painting products and cathode ray tubes, like TVs and computer monitors, to a Household Hazardous Waste Collection Center (HHWCC) For a HHWCC near you call (714) 834-6752 or visit www oclandfills com Do not hose down your driveway, sidewalk or patio to the street, gutter or storm drain Sweep up debris and dispose of it in the trash Automotive Take your vehicle to a commercial car wash whenever possible If you wash your vehicle at home, choose soaps, cleaners, or detergents labeled non-toxic, phosphate- free or biodegradable Vegetable and citrus-based products are typically safest for the environment Do not allow washwater from vehicle washing to drain into the street, gutter or storm drain Excess washwater should be disposed of in the sanitary sewer (through a sink or toilet) or onto an absorbent surface like your lawn Monitor your vehicles for leaks and place a pan under leaks Keep your vehicles well maintained to stop and prevent leaks Never pour oil or antifreeze in the street, gutter or storm drain Recycle these substances at a service station, a waste oil collection center or used oil recycling center For the nearest Used Oil Collection Center call 1-800-CLEANUP or visit www 1800cleanup org Never allow pollutants to enter the street, gutter or storm drain!

Help Prevent Ocean Pollution: Recycle at Your Local Used Oil Collection Center CENTRAL COUNTY For more information, please call the Orange County Stormwater Program at 1-877-89-SPILL (1-877-897-7455) or visit www.watersheds.com. For information about the proper disposal of household hazardous waste, call the Household Waste Hotline at (714) 834-6752 or visit www.oclandfills.com. For additional information about the nearest oil recycling center, call the Used Oil Program at 1-800-CLEANUP or visit www.cleanup.org. Did you know that just one quart of oil can pollute 250,000 gallons of water? A clean ocean and healthy creeks, rivers, bays and beaches are important to Orange County. However, not properly disposing of used oil can lead to water pollution. If you pour or drain oil onto driveways, sidewalks or streets, it can be washed into the storm drain. Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering the ocean. Help prevent water pollution by taking your used oil to a used oil collection center. Included in this brochure is a list of locations that will accept up to five gallons of used motor oil at no cost. Many also accept used oil filters. Please contact the facility before delivering your used oil. This listing of companies is for your reference and does not constitute a recommendation or endorsement of the company. Please note that used oil filters may not be disposed of with regular household trash. They must be taken to a household hazardous waste collection or recycling center in Anaheim, Huntington Beach, Irvine or San Juan Capistrano. For information about these centers, visit www.oclandfills.com. Please do not mix your oil with other substances!

You Are Responsible for a Sewage Spill Caused by a Blockage or Break in Your Sewer Lines! Grease builds up inside and eventually blocks sewer pipes. Grease gets into the sewer from food establishments, household drains, as well as from poorly maintained commercial grease traps and interceptors. Structure problems caused by tree roots in the lines, broken/cracked pipes, missing or broken cleanout caps or undersized sewers can cause blockages. Infiltration and inflow (I/I) impacts pipe capacity and is caused when groundwater or rainwater enters the sewer system through pipe defects and illegal connections. Time is of the essence in dealing with sewage spills. You are required to immediately: Control and minimize the spill. Keep spills contained on private property and out of gutters, storm drains and public waterways by shutting off or not using the water. Use sandbags, dirt and/or plastic sheeting to prevent sewage from entering the storm drain system. Clear the sewer blockage. Always wear gloves and wash your hands. It is recommended that a plumbing professional be called for clearing blockages and making necessary repairs. Always notify your city sewer/public works department or public sewer district of sewage spills. If the spill enters the storm drains also notify the Health Care Agency. In addition, if it exceeds 1,000 gallons notify the Office of Emergency Services. Refer to the numbers listed in this brochure. Caution Allowing sewage from your home, business or property to discharge to a gutter or storm drain may subject you to penalties and/or out-of-pocket costs to reimburse cities or public agencies for clean-up and enforcement efforts. See Regulatory Codes & Fines section for pertinent codes and fines that apply. What to Look For You Could Be Liable Sewage spills can be a very noticeable gushing of water from a manhole or a slow water leak that may take time to be noticed. Don’t dismiss unaccounted-for wet areas. Look for: !Drain backups inside the building. !Wet ground and water leaking around manhole lids onto your street. !Leaking water from cleanouts or outside drains. !Unusual odorous wet areas: sidewalks, external walls or ground/landscape around a building. Rev 4/06printed on recycled paper Common Causes of Sewage Spills Overflowing cleanout pipe located on private property Keep people and pets away from the affected area. Untreated sewage has high levels of disease-causing viruses and bacteria. Call your local health care agency listed on the back for more information. DTP113 Sewage spills occur when the wastewater being transported via underground pipes overflows through a manhole, cleanout or broken pipe. Sewage spills can cause health hazards, damage to homes and businesses, and threaten the environment, local waterways and beaches.

They may respond and assist with contain- ment, relieving pipe blockages, and/or clean-up of the sewage spill, especially if the spill is flowing into storm drains or onto public property. A property owner may be charged for costs incurred by these agencies responding to spills from private properties . How You Can Prevent Sewage Spills A property owner's sewer pipes are called service laterals and are connected to larger local main and regional trunk lines. Service laterals run from the connection at the home to the connection with the public sewer (including the area under the street). These laterals are the responsibility of the property owner and must be maintained by the property owner. Many city agencies have adopted ordinances requiring maintenance of service laterals. Check with your city sewer/local public works department for more information. Operation and maintenance of local and regional sewer lines are the responsi- bility of the city sewer/public works depart- ments and public sewer districts. Preventing Grease Blockages The drain is not a dump! Recycle or dispose of grease properly and never pour grease down the drain. Homeowners should mix fats, oils and grease with absor- bent waste materials such as paper, coffee grounds, or kitty litter and place it in the trash. Wipe food scraps from plates and pans and dump them in the trash. Restaurants and commercial food service establishments should always use “Kitchen Best Management Practices.” These include: !Collecting all cooking grease and liquid oil from pots, pans and fryers in covered grease containers for recycling. !Scraping or dry-wiping excess food and grease from dishes, pots, pans and fryers into the trash. !Installing drain screens on all kitchen drains. !Having spill kits readily available for cleaning up spills. !Properly maintaining grease traps or interceptors by having them serviced regularly. Check your local city codes. !City Sewer/Public Works Departments— Responsible for protecting city property and streets, the local storm drain system, sewage collection system and other public areas. !Pub l i c Sewe r/Sanitation District— Responsible for collecting, treating and disposing of wastewater. !County of Orange Health Care Agency— Responsible for protecting public health by closing ocean/bay waters and may close food-service businesses if a spill poses a threat to public health. !Regional Water Quality Control Boards— Responsible for protecting State waters. !Orange County Stormwater Program— Responsible for preventing harmful pollutants from being discharged or washed by stormwater runoff into the municipal storm drain system, creeks, bays and the ocean. 2 3 1 Never put grease down garbage disposals, drains or toilets. Perform periodic cleaning to eliminate grease, debris and roots in your service laterals.

If you have other suggestions, please contact your city’s stormwater representatives or call the Orange County Stormwater Program. C lean beaches and healthy creeks, rivers, bays and ocean are important to Orange County. However, many common activities can lead to water pollution if you’re not careful. Fertilizers, pesticides and other chemicals that are left on yards or driveways can be blown or washed into storm drains that flow to the ocean. Overwatering lawns can also send materials into storm drains. Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering our waterways. You would never pour gardening products into the ocean, so don’t let them enter the storm drains. Follow these easy tips to help prevent water pollution. Printed on Recycled Paper Tips for Landscape and GardeningTips for Landscape & Gardening Never allow gardening products or polluted water to enter the street, gutter or storm drain. General Landscaping Tips Protect stockpiles and materials from wind and rain by storing them under tarps or secured plastic sheeting. Prevent erosion of slopes by planting fast-growing, dense ground covering plants. These will shield and bind the soil. Plant native vegetation to reduce the amount of water, fertilizers, and pesticide applied to the landscape. Never apply pesticides or fertilizers when rain is predicted within the next 48 hours. Garden & Lawn Maintenance Do not overwater. Use irrigation practices such as drip irrigation, soaker hoses or micro spray systems. Periodically inspect and fix leaks and misdirected sprinklers. Do not rake or blow leaves, clippings or pruning waste into the street, gutter or storm drain. Instead, dispose of green waste by composting, hauling it to a permitted landfill, or recycling it through your city’s program. Use slow-release fertilizers to minimize leaching, and use organic fertilizers. Read labels and use only as directed. Do not over-apply pesticides or fertilizers. Apply to spots as needed, rather than blanketing an entire area. Store pesticides, fertilizers and other chemicals in a dry covered area to prevent exposure that may result in the deterioration of containers and packaging. Rinse empty pesticide containers and re-use rinse water as you would use the product. Do not dump rinse water down storm drains. Dispose of empty containers in the trash. When available, use non-toxic alternatives to traditional pesticides, and use pesticides specifically designed to control the pest you are targeting. For more information, visit www.ipm.ucdavis.edu. If fertilizer is spilled, sweep up the spill before irrigating. If the spill is liquid, apply an absorbent material such as cat litter, and then sweep it up and dispose of it in the trash. Take unwanted pesticides to a Household Hazardous Waste Collection Center to be recycled. Locations are provided below. Household Hazardous Waste Collection Centers Anaheim: 1071 N.

Proper Maintenance Practices for Your Business The Ocean Beginsat Your Front Door PROJECT PREVENTION Help Prevent Ocean Pollution: Preventing water pollution at your commercial/industrial site Clean beaches and healthy creeks, rivers, bays and ocean are important to Orange County. However, many landscape and building maintenance activities can lead to water pollution if you’re not careful. Paint, chemicals, plant clippings and other materials can be blown or washed into storm drains that flow to the ocean. Unlike water in sanitary sewers (from sinks and toilets), water in storm drains is not treated before entering our waterways. You would never pour soap or fertilizers into the ocean, so why would you let them enter the storm drains? Follow these easy tips to help prevent water pollution. Some types of industrial facilities are required to obtain coverage under the State General Industrial Permit. For more information visit: www.swrcb.ca.gov/stormwater/industrial.html Printed on Recycled Paper Tips for Pool Maintenance Call your trash hauler to replace leaking dumpsters. Do not dump any toxic substance or liquid waste on the pavement, the ground, or near a storm drain. Even materials that seem harmless such as latex paint or biodegradable cleaners can damage the environment. Recycle paints, solvents and other materials. For more information about recycling and collection centers, visit www.oclandfills.com. Store materials indoors or under cover and away from storm drains. Use a construction and demolition recycling company to recycle lumber, paper, cardboard, metals, masonry, carpet, plastic, pipes, drywall, rocks, dirt, and green waste. For a listing of construction and demolition recycling locations in your area, visit www.ciwmb.ca.gov/recycle. Properly label materials. Familiarize employees with Material Safety Data Sheets. Landscape Maintenance Compost grass clippings, leaves, sticks and other vegetation, or dispose of it at a permitted landfill or in green waste containers. Do not dispose of these materials in the street, gutter or storm drain. Irrigate slowly and inspect the system for leaks, overspraying and runoff. Adjust automatic timers to avoid overwatering. Follow label directions for the use and disposal of fertilizers and pesticides. Do not apply pesticides or fertilizers if rain is expected within 48 hours or if wind speeds are above 5 mph. Do not spray pesticides within 100 feet of waterways. Fertilizers should be worked into the soil rather than dumped onto the surface. If fertilizer is spilled on the pavement or sidewalk, sweep it up immediately and place it back in the container. Building Maintenance Never allow washwater, sweepings or sediment to enter the storm drain. Sweep up dry spills and use cat litter, towels or similar materials to absorb wet spills. Dispose of it in the trash. If you wash your building, sidewalk or parking lot, you must contain the water. Use a shop vac to collect the water and contact your city or sanitation agency for proper disposal information. Do not let water enter the street, gutter or storm drain. Use drop cloths underneath outdoor painting, scraping, and sandblasting work, and properly dispose of materials in the trash. Use a ground cloth or oversized tub for mixing paint and cleaning tools. Use a damp mop or broom to clean floors. Cover dumpsters to keep insects, animals, rainwater and sand from entering. Keep the area around the dumpster clear of trash and debris. Do not overfill the dumpster. PROJECT PREVENTION Proper Maintenance Practices for your Business Never Dispose of Anything in the Storm Drain.
