EXECUTIVE SUMMARY A. Central San's Wastewater Treatment Facilities Central San owns and operates a municipal wastewater collection system and a secondary wastewater treatment plant rated for 53.8 million gallons per day. Central San collects, treats, recycles, and discharges wastewater from nearly 500,000 residents and more than 15,000 businesses within 10 cities and four unincorporated communities in central Contra Costa County. The collection area covers 145 square miles and includes over 1,500 miles of sewer pipelines. Central San's treatment plant consists of screening, pre-aeration, grit removal, primary sedimentation, anaerobic selection, biologically activated sludge secondary treatment, secondary clarification, and ultraviolet disinfection. Central San sends approximately 600 million gallons of treated effluent each year to a dual-media tertiary treatment plant to produce recycled water. The treatment plant uses about 400 million gallons of recycled water, with the balance of 200 million gallons of recycled water sent to a portion of Central San's service area primarily for landscape irrigation. The remaining treated effluent discharges via a deep-water outfall to Suisun Bay. B. Central San's Pollution Prevention Program Central San has conducted several award-winning P2 programs in its service area and beyond. P2 activities are often multifunctional programs requiring coordination among several operating units at Central San, which, when taken together, contribute to an effective P2 Program. Central San's P2 activities include the following: • Education Outreach o Pipe Protectors for kindergarten through 5t" grade students o Go With the Flow for kindergarten through 5t"-grade students o Delta Discovery Voyage for 5t" grade students o Next Gen Sewer Science for high school students • The Household Hazardous Waste Collection Program (HHWCP) provides a solution for the proper disposal of hazardous household chemical products and hazardous wastes produced by small businesses. • Communication Services staff provide regular outreach and educational materials to the public and Central San employees about how to keep toxins out of sewers and storm drains, tips for "going green," and other information to encourage fewer toxic choices and purchases. • Environmental Compliance staff perform wastewater inspections, stormwater inspections, and P2 audits at businesses and industries in Central San's service area. • Laboratory staff sample and analyze constituents to identify and monitor pollutants of concern and evaluate the effectiveness of P2 efforts. Central San 2023 Pollution Prevention Annual Report Page 4 April 25, 2024 Special Board Meeting Agenda Packet- Page 43 of 110 Page 13 of 33 • Central San staff provide representation, leadership, project management, and technical support on local, regional, statewide, and national committees to collaborate on P2 campaigns, projects, and issues. Central San works with the following agencies and organizations to take advantage of local, regional, statewide, and national efforts for reducing wastewater pollution and protecting water quality: • Bay Area Clean Water Agencies (BACWA) • Bay Area Pollution Prevention Group (BAPPG) • California Association of Sanitation Agencies (CASA) • California Water Environment Association (CWEA) • Central Contra Costa Solid Waste Authority • Contra Costa Clean Water Program (CCCWP) • Contra Costa County Hazardous Materials Commission • Contra Costa Environmental Health • Contra Costa Green Business Program (CCGBP) • National Association of Clean Water Agencies (NACWA) • North American Hazardous Materials Management Association (NAHMMA) Central San participates in BAPPG, a subcommittee of BACWA, to coordinate P2 activities and reduce toxic pollutants discharged into the San Francisco Bay and local waterways. The efforts of BAPPG are summarized in BAPPG's annual report. C. Central San's 2023 Pollutants of Concern Central San's pollutants of concern for 2023 comprised three groups of pollutants as described below. 1. Priority Pollutants Pollutants with effluent limits in Central San's 2022 National Pollutant Discharge Elimination System (NPDES) Permit or in the San Francisco Bay Mercury and Polychlorinated Biphenyls (PCBs) Watershed Permit are classified as priority pollutants. Fats, oils, grease (FOG), and flushable products are also classified as priority pollutants because of their significant contribution to sanitary sewer overflows. Although Central San does not have a selenium effluent limit in the current NPDES permit, a Total Maximum Daily Load (TMDL) has been established for selenium in the North San Francisco Bay. Central San's Priority Pollutants for 2023 were: Central San 2023 Pollution Prevention Annual Report Page 5 April 25, 2024 Special Board Meeting Agenda Packet- Page 44 of 110 Page 14 of 33 • Mercury • PCBs • Dioxins • Ammonia • Cyanide • FOG • Copper • Flushable and Non-Dispersible Products • Acrylonitrile • Selenium 2. Watch List Pollutants Central San's Watch List pollutants appeared in previous NPDES Permits but did not have effluent limits in the 2022 NPDES Permit. Pollutants are removed from the watch list if they have not had effluent limits in Central San's NPDES Permit for two permit cycles. Central San did not have any watch list pollutants for 2023. 3. Pollutants of Emerging Concern This category includes chemicals and products emerging as pollutants of concern to water quality. It also includes pollutants for which TMDLs are being developed. The following were Central San's pollutants of emerging concern for 2023: • Pesticides • Nonylphenol Ethoxylates • Per- and Polyfluoroalkyl • Pharmaceuticals and Substances (PFAS) personal-care products • Nanoparticles Microplastics Central San 2023 Pollution Prevention Annual Report Page 6 April 25, 2024 Special Board Meeting Agenda Packet- Page 45 of 110 Page 15 of 33 D. Central San's 2023 Summary of P2 Activities The following table provides the results of the activities that Central San committed to completing in the 2023 P2 Plan. Table 1.
