CCCSD has been providing recycled water for in -plant usage, irrigation customers and a range of commercial uses since 1996. In 2013, CCCSD provided approximately 638 acre -feet (AF), or 208 million gallons (MG), of recycled water to a variety of customers in Pleasant Hill, Concord and Martinez near the Interstate 680 freeway. Recycled water was used for landscape irrigation at schools, parks, golf courses, and street medians and for commercial uses such as truck washing, concrete manufacturing, dust control, and washing kennels at the local animal shelter. In addition to supplying recycled water to offsite customers, CCCSD used approximately 1,228 AF, or 400 MG, of recycled water internally at CCCSD's wastewater treatment plant in Martinez for process water and landscape irrigation. The total volume of recycled water provided by CCCSD in 2013 for offsite customer locations and internal uses was approximately 1,866 AF, or 608 MG. This annual report covers CCCSD's production and distribution of tertiary- treated recycled water over the period of January through December 2013. Figure 1 is a map showing the location of each recycled water customer. Table 1 provides a summary of recycled water usage for calendar year 2013 by reuse application category, as requested by the Regional Board. Table 2 shows the monthly usage of recycled water by customer. Figure 1 is a map showing the location of each recycled water customer. Secondary effluent is tertiary treated through sand /anthracite filtration and chlorine disinfection. Recycled water is stored in a covered seven million gallon reservoir prior to distribution to customers. Tables 3 through 14 represent the 2013 water quality characteristics. Our 2013 Recycled Water Site Inspection Reports follow these tables. All sampling and analyses were performed in accordance with Regional Water Quality Control Board (RWQCB) Order No. 96 -011. In 2013, our recycled water program complied with all applicable tertiary recycled water quality standards. However, in the preparation of this report, staff realized that two of our recycled water customer site inspections were inadvertently missed in 2013. Upon discovery, particularly since these sites are currently irrigating due to the lack of rain, staff conducted inspections of these missed sites and included those completed inspection forms in this report. Our procedures have been modified to prevent this from happening next year and these sites will be inspected again later in 2014. FUTURE EXPANSION CCCSD continues to seek opportunities and partnerships to expand recycled water use, add new customers, and obtain financial assistance to build additional recycled water facilities. CCCSD's recycled water projects have been on the forefront of the development of new and innovative uses of recycled water. The interior hot water use of recycled water for dog kennel wash -down was the first -of- its -kind in California. CCCSD's expansion into the provision of dual plumbing for interior uses for toilet and urinal flushing as well as the proposed use of recycled water for cooling towers and boiler feed water at local petroleum refineries represent some of recycled water's most advanced uses. The following describes CCCSD's work in 2013 to expand recycled water use. Concord Recycled Water Landscape Project In 2013, CCCSD made progress on the construction of the Concord Recycled Water Landscape Project, which will provide up to 190 AFY (62 MG /year) of recycled water for landscape irrigation at businesses and street medians in the Diamond /Meridian Park Boulevard area of Concord. Construction of the 2.3 miles of the mainline distribution pipeline was completed in 2013. The bid package for the customer connections for this project is in progress as of the writing of this report. The project will ultimately add up to 36 new customer connections and more than double CCCSD's recycled water connections. The customer connections phase (including installation of meters and connections to customer irrigation systems) is expected to be completed in 2014. In 2011, the project was awarded a $1,030,000 Proposition 84 Implementation Grant from the California Department of Water Resources and a $97,000 Title XVI planning grant from the US Bureau of Reclamation (USBR). CCCSD continues to seek federal legislative authorization and appropriation for an additional $1.8 million in Title XVI funding for the project. The Concord Recycled Water Landscape Project is covered by the Zone One Project Agreement with the Contra Costa Water District (CCWD) discussed below. Recycled Water Zone One Project CCCSD has an agreement with CCWD to allow CCCSD to supply up to 1,162 AFY (379 MG /year) of recycled water for landscape irrigation and light commercial uses in the Zone One Project area, which consists of portions of Martinez, Pleasant Hill and Concord near the Interstate 680 freeway. CCCSD constructed and operates approximately 11 miles of recycled water distribution pipelines in these areas and provides recycled water service to 35 sites. During 2013, CCCSD focused its efforts on expanding the use of recycled water by advancing and implementing the following dual - plumbing applications: 1. CCCSD Headquarters Office Building (HOB) — As part a seismic improvements project, and after successful completion of a cross - connection test, the toilets and urinals on all 2 four floors of CCCSD's HOB were connected to recycled water. A total of 14 toilets and 6 urinals will use an estimated 500,000 gallons of recycled water per year. 2. Diablo Valley College (DVC) Commons — DVC completed construction of one of its two new classroom and faculty buildings of approximately 86,000 square feet that will use recycled water for toilet /urinal flushing and landscape irrigation of interior courtyards. In 2012, CCCSD obtained California Department of Public Health (CDPH) approval for the project. DVC completed construction of the first building in 2013 and upon successful completion of a cross - connection test in December 2013 is now using recycled water. The second building is expected to be completed in 2014. A total of 35 toilets and 9 urinals will use recycled water for flushing with an estimated annual recycled water use of 1,000,000 gallons per year. The use of recycled water is one of the sustainable design features that will enable the new buildings to achieve a Leadership in Energy and Environmental Design (LEED) Gold Certification when completed. 3. Pleasant Oaks Park Remodel — In 2013, Pleasant Hill Recreation and Park District, an existing CCCSD recycled water landscape irrigation customer since 2004, began a major renovation of their Pleasant Oaks Park, including renovation of their Recreation Building to include dual plumbing for toilet and urinal flushing with recycled water. In June 2013, CCCSD received CDPH approval for this new use. As of the writing of this report, construction is drawing to a close and a cross connection test is anticipated for February 2014. CCCSD is continuing efforts to identify and connect additional cost - effective recycled water customers in the Zone One project area, particularly those located near existing recycled water pipelines. Contra Costa County Refinery Recycled Water Project CCCSD continued efforts to develop a refinery recycled water project that would provide up to 22,500 AFY (20 MG /day) of recycled water to the Shell Martinez Refinery and the Tesoro Refinery for use as cooling tower makeup water and as boiler feedwater. The refineries are currently supplied by CCWD with untreated Delta water via the Contra Costa Canal, which is predominantly supplied by the USBR's Central Valley Project (CVP). The refinery project is particularly attractive because it represents a large year -round demand for recycled water and it could potentially make use of existing recycled water conveyance and storage facilities already in place from CCCSD's treatment plant to each refinery. The planning -level cost estimate for the refinery project could be up to $100 million, depending on whether the full -scale project is implemented. As a result, CCCSD needs financial assistance and /or project partners to make the project cost - effective. In this regard, CCCSD is actively pursuing federal grant funding through the federal Water Resources Development Act (WRDA) and the Title XVI Program and continues to look for possible sources of state funding. In 2011, CCCSD was awarded an $180,000 Title XVI planning grant from the USBR to fund 50% of the costs to prepare a feasibility study and environmental documentation for the proposed project. The USBR requires the project sponsor to prepare a feasibility study to 3 4 demonstrate that the proposed project is a viable, well thought-out and long-term source of wa ter that justifies the expenditure of federal funds for construction of the proposed facilities. In order to complete the feasibility study , a water supply yield study was completed by RMC Water and Environment in association with MBK Engineers in May 2013, in partnership with CCWD. The yield study determined that due to the limitations in the capacity available in the operation of the CVP, the true yield of the refinery project is just about half of what would be delivered (for either the 5 or 20 MGD-sized projects). As depicted in the following graphic, the water freed up from a 20 MGD (22 thousand acre-feet (TAF)) refinery recycled water project would result in 21 TAF/year in reduced CCWD CVP diversions, 11 TAF/year in increased delta outflow , 2.6 TAF/year of additional upstream storage for future use, 10 T AF/year in increased exports and a slight reduction (0.7 TAF/year) in CCWD transfer water used. The results of the study were reviewed by the U SBR and since the project appears to be viable, CCCSD continued its contract with RMC Water and Environment to prepare a Title XVI feasibility study. Completion of the feasibility study is anticipated by mid-2014. Development of Recycled Water Projects on CCCSD Buffer Properties CCCSD has been exploring options for recycled water projects on vacant buffer land owned by CCCSD near its waste water treatment facilities in Martinez. These options include using recy cled water for growing agricultural products. Several nearby properties already have recycled water supply pipelines on or adjacent to them, which reduces implementation costs . CCCSD is continuing to evaluate a proposal from a local community organization to develop and operate a demonstration farm/garden on a 33-acre CCCSD owned parcel adjacent to the 5 treatment plant. This innovative proposal includes areas to grow food crops to donate fresh produce to school lunch programs and the Food Bank, as well as community gardening plots. The project would also be used to demonstrate the science and benefits of recycled water and sustainable gardening and farming practices (e.g., avoiding the use of pesticides and other toxic products). T he proposed farm project could potentially serve as a model for other wastewater agencies that have available land near their treatment facilities and would like to increase water recycling. Concord Naval Weapons Station Redevelopment The planned redevelopment of the Concord Naval Weapons Station property provides an excellent opportunity to expand recycled water use. In 2009, the City of Concord selected a preferred development plan (Clustered Villages concept) consisting of a mixture of commercial, residential, institutional, and recreational land uses interspersed between parks and open space. This mixture of land uses w ill create opportunities to use recycled water, not only for landscape irrigation but also for non-potable uses such as toilet flushing and cooling towers in commercial buildings. Recycled water demand for the new development is estimated to be approximately 2,800 AFY (900 MG/year) at build-out. In 2012, CCCSD completed a Recycled Water Facilities Plan for the Naval Weapons Station redevelopment that evaluated alternatives and costs for new recycled water infrastructure needed to meet the anticipated demand . The redevelopment of the property and construction of supporting recycled water infrastructure is not expected to begin for five to ten years because of additional planning work that must be completed by the City of Concord and the Navy before property ownership can be transferred from the Navy to the City of Concord and/or a developer. Diablo Country Club Satellite Recycled Water Project In 2012, CCCSD entered into a Memorandum of Agreement with the Diablo Country Club and EBMUD (the water purveyor) to evaluate construction of a satellite recycled water treatment plant to supply irrigation water to the Club’s 18 -hole golf course located near Danville . CCCSD would provide wastewater from its sewerage collection system and receive solids returned from the satellite plant. The Diablo Country Club has proposed to finance the ca pital and operati ng costs of the satellite plant and own and operate the facilities. A Satellite Recycled Water Treatment Plant Feasibility Study was completed in 2012 by the Country Club with assistance from CCCSD and EBMUD. The study found that the best use of resources to meet long term sustainable water supply needs for the golf course was to utilize a blend of recycled water, ground water, and potable water for irrigation. Further investigations into the regulatory, environmental and design requirements continued in 2013. In 2014, CCCSD anticipates receiving a project application from the County Club for CCCSD to be the lead agency for the CEQA process for the project. TRUCK FILL HYDRANT PROGRAM During the last drought in 2009, CCWD recalled its potable hydrant meters to conserve water, and contractors were no longer able to obtain water from potable water hydrants for construction activities and other needs. To help address this problem , CCCSD initiated a truck fill hydrant program in 2009 to provide recycled water to contractors, companies, and 6 public agencies for dust control, compaction, irrigation and other non-potable uses. CCCSD installed a purple recycled water hydrant in Concord near the Interstate 680/Highway 4 interchange and provided portable hydrant meters to contractors and others who could no longer obtain water from potable water hydrants. Over the last several years the demand for recycled water from CCCSD’s truck fill program has been limited due to more normal rainfall conditions and an easing of prior drought restrictions by local water agencies. In 2013, CCCSD had no recycled water hydrant sales. However, CCCSD will continue to make its truck fi ll program available to the community as needed to respond to future drought situations. OPERATIONS AND MAINTENANCE UPDATE CCWD field crews have performed maintenance and repair work on CCCSD’s recycled water distribution system under contract since 2004. CCWD ’s cross-connection control specialists also assist CCCSD with cross-connection inspections for new recycled water sites and testing and recertification of existing sites where piping modifications have been made. In 2013, CCCSD Maintenance Crew Leader Hamid Tehrani obtained certification as a cross connection control specialist and is now qualified to certify CCCSD’s cross connection tests. In 2013, CCCSD Planning staff, in collaboration with Plant Operations staff, continued investigating optimization options to improve our filter plant performance including updating our coagulant control systems and evaluating the potential effectiveness of cleaning our existing filter media. CUSTOMER TRAINING CCCSD has an ongoing customer training program to educate recycled water customers about the precautions and appropriate uses of recycled water and train new Recycled Water Site Supervisors . During annual site inspections, CCCSD provides refresher training to customer staff where needed and verifies that each customer has up to date training m aterials, including CCCSD ’s brochures and guidance documents on the proper use of recycled water. In 2013, CCCSD began updating its customer training program for dual plumbing systems to reflect recent updates to the plumbing code related to recycled water u se in interior applications, such as toilet and urinal flushing. This update will be completed and incorporated into all customer guides in 2014. REGIONAL ALLIANCES TO DEVELOP RECYCLED WATER PROJECTS Western Recycled Water Coalition (Formerly Bay Area Recycled Water Coalition) Since 2009, CCCSD has been a member of the Bay Area Recycled Water Coalition, which is a partnership of 14 agencies committed to developing recycled water as a resource for municipal, industrial, commercial and agricultural uses across the San Francisco Bay Area. In 2013, the Coalition expanded to include agencies outside of the Bay Area, so the name was adjusted accordingly to reflect that. The Western Recycled Water Coalition continues a successful regional approach to pursing recycled water funding and was instrumental in helping CCCSD to secure the Title XVI planning grants for the Concord Recycled Water Landscape Project and the Refinery Project. As part of CCCSD’s support of the Coa lition in 7 2013, CCCSD’s Graphic Artist designed a new 6-page Coalition brochure to educate congressional leaders about potential recycled water projects and to attract new members. Bay Area Integrated Regional Water Planning In 2013 , CCCSD collaborat ed with other Bay Area agencies to update the Bay Area Integrated Regional Water Management Plan (IRWMP), which was originally prepared in 2006. The IRWMP is a nine-county effort to coordinate and improve water supply reliability, protect water quality, manage flood protection, maintain public health standards, protect habitat and watershed resources, and enhance the overall health of the bay. Projects listed in the IRWMP are eligible to apply for state grant money, such as Proposition 84 funding, which is providing grant funding for the Concord Recycled Water Landscape Project. CCCSD recycled water projects that are currently being implemented or may be initiated within the next three to five years have been listed in the latest IRWMP update including the Recycled Water Zone One Project; Concord Recycled Water Landscape Project and Contra Costa County Refinery Recycled Water Project. SALT AND NUTRIENT MANAGEMENT PLAN COMPLIANCE On February 3, 2009, the California State Water Resources Control (SWRCB) adopted a Statewide Recycled Water Policy establishing uniform requirements for the use of recycled water. Among other provisions, the Policy requires regions overlying groundwater basins in the State where recycled water use is occurring and planned for the future to develop a salt and nutrient management plan by May 2014. The SWRCB has indicated it plans to develop a streamlined reporting process by which groundwater basins with limited use of the groundwater resources or those basins which are not likely to have adverse impacts from r ecycled water irrigation (such as those within CCCSD’s service area) can prepare simplified salt and nutrient management plans . Due to the very limited extent that groundwater is used a s a potable water supply in CCCSD’s servic e area, it appears that the basins underlying CC CSD’s recycled water current and planned service areas would likely qualify for the streamlined reporting process. The specific reporting requirements are currently being developed by the SWRCB. In the meantime, as part of the Bay Area IRWMP update process, templates are being developed that will allow Bay Area agencies to prepare their salt and nutrient management plans in an efficient and streamlined manner. These templates should be available in 2014 and will be used by CCCSD as a basis to develop a site specific plan for CCCSD’s limited use groundwater basins . LIMITS TO EXPANSION OF RECYCLED WATER CCCSD’s Board of Directors has consistently expressed an interest in maximizing recycled water opportunities. However, there are many institutional and financial impediments that are outside the control of CCCSD. On the institutional side, CCCSD must work with the potable water purveyors in our service area and either wholesale recycled water to them or obtain their permission to purvey recycled water. Some Northern California potable water purveyors assert they have significant sunk costs in existing facilities, and contend the California duplication of services law allows them to recoup stranded costs if recycled water is made available . Although recycled water producers may dispute the applicability of this law, the issue can add another institutional barrier and significant additional costs to recycled water 8 projects . In addition, even when institutional issues are overcome, the cost to construct new recycled water treatment and conveyance facilities can be high. For example, recycled water projects often require construction of pipelines through congested urban areas or require additional treatment facilities to increase capacity. When all of these costs are added together, the unit cost of recycled water can exceed the cost of other available, but less- sustainable, water supplies. Although recycled water projects may have substantial additional quantifiable benefits versus conventional alternatives, additional sources of funding are needed to make recycled water projects more competitive with other alternatives a vailable to local water purveyors. The limited availability of state and federal funding for recycled water projects in the past has restricted the growth of CCCSD’s recycled water program. Despite these challenges, CCCSD is increasing recycled water use in the Bay Area by developing new recycled water projects where economically and financially viable. !( !( !(!(!( !( !( !( !( !( !( !( !( !( !( !(!( !( !( !(!( !(!(!( !( !( !( !( !( !( !( !( !( !( " Martinez Reservoir Walnut Creek Contra Costa Mallard Reservoir CCCSD HEADQUARTERS §¨¦680 ¬«242 ¬«4 §¨¦680 Pac h e c o Blvd Mor e l l o Ta y l o r Blvd M o n u m e n t Bl v d W i l l o w P a s s R d Oak Grove Rd Contra Costa Blvd Ar n o l d B l v d Ave C h i l p a n c i n g o P k y Blum Rd I m h o f f D r Co n c o r d A v e Gr e g o r y Ln REW CLEARWELL MARTINEZ WA T E R SERVIC E AR E A CCWD EBMUD ¬«4 MALTBY PUMP STATION COUNTY QUARRY CC TOPSOIL COUNTY CORP.

COMMITTEE FROM: MELODY LABELLA, PROVISIONAL ASSOCIATE ENGINEER 9%iX SUBJECT: DRAFT 2014 POLLUTION PREVENTION PLAN Attached, please find the draft 2014 Pollution Prevention (132) Plan for your review. Staff prepares this Plan as an element of our annual P2 Report, which is due to the Regional Board on February 28th each year. Staff has organized our P2 Plan into four sections, as follows: 1. Priority Pollutants are pollutants that have effluent limits in CCCSD's 2013 National Pollutant Discharge Elimination System ( NPDES) Permit or in the Bay Area Watershed Permit. Fats, oils and grease (FOG) and flushable products are included, because of their tendency to contribute to sanitary sewer overflows. 2. Watch List Pollutants are pollutants that appeared in CCCSD's previous NPDES Permit(s), but do not have limits in CCCSD's 2013 NPDES Permit. Pollutants are dropped off CCCSD's Watch List if they have not had effluent limits in our NPDES Permit for two permit cycles. 3. Pollutants of Emerging Concern are pollutants that are emerging as a potential water quality concern and include pollutants that have Total Maximum Daily Loads (TMDLs) in development. 4. Continuous P2 Efforts are actions that CCCSD commits to that reduce multiple pollutants of all kinds.
