ACKNOWLEDGMENTS Central Contra Costa Sanitary District's Pollution Prevention Program is a testament of every employee and Board member's commitment to the mission of protecting the environment. The following groups deserve special recognition for their contributions to this report: • Environmental and Regulatory Compliance Division • Communication Services and Intergovernmental Relations Central San 2019 Pollution Prevention Annual Report Page 1 April 16, 2020 Regular Board Meeting Agenda Packet- Page 19 of 208 Page 5 of 27 II. EXECUTIVE SUMMARY A. Central Contra Costa Sanitary District's Wastewater Treatment Facilities The Central Contra Costa Sanitary District (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 494,300 residents and more than 3,000 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. Each year, Central San sends approximately 600 million gallons of treated effluent 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 (P2) 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, 1St, and 2nd grade students o Water Wizards for 3rd 41" and 5t" grade students o Sewer Science for high school students o Delta Discovery Voyage for 5t" grade students • The Household Hazardous Waste Collection Program (HHWCP) provides a solution for proper disposal of hazardous household products and chemicals. • Communication Services staff provide regular outreach and educational materials to the public and Central San employees about how to keep toxics out of sewers and storm drains, tips for "going green", and other information to encourage less 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 2019 Pollution Prevention Annual Report Page 2 April 16, 2020 Regular Board Meeting Agenda Packet- Page 20 of 208 Page 6 of 27 • 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) • 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) 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 2019 Pollutants of Concern Central San's pollutants of concern for 2019 comprised three groups of pollutants, described below. 1. Priority Pollutants Pollutants with effluent limits in Central San's 2017 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 2019 were: • Mercury • PCBs • Dioxins • Ammonia • Cyanide • FOG • Copper • Flushable and Non-Dispersible Products • Acrylonitrile • Selenium Central San 2019 Pollution Prevention Annual Report Page 3 April 16, 2020 Regular Board Meeting Agenda Packet- Page 21 of 208 Page 7 of 27 2. Watch List Pollutants Central San's Watch List pollutants appeared in previous NPDES Permits but did not have effluent limits in the 2017 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's watch list pollutant for 2019 was: • Bis (2-ethylhexyl) phthalate 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 2019: • Pesticides • Pharmaceuticals and • Flame retardants personal-care products • Nanoparticles • Microplastics • Nonylphenol Ethoxylates • Air toxics Central San 2019 Pollution Prevention Annual Report Page 4 April 16, 2020 Regular Board Meeting Agenda Packet- Page 22 of 208 Page 8 of 27 D. Central San's 2019 Summary of P2 Activities The following table provides the results of the activities that Central San committed to complete in the 2019 P2 Plan. Table 1.

Central San's 2020 P2 Plan Central San's 2020 P2 Plan reflects continued efforts to mitigate pollutants of concern. For many pollutants, there are no reasonable methods to assess the effectiveness of Central San's P2 efforts. In these cases, success is measured by the number of events conducted, the number of flyers distributed, the number of participants using the HHWCP, etc. Table 2 on the following pages outlines Central San's P2 Plan for 2020.
