III. 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 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 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 5th grade students
o Go With the Flow for kindergarten through 5th grade students
o Delta Discovery Voyage for 5th grade students
o 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 2022 Pollution Prevention Annual Report Page 3
March 16, 2023 Regular Board Meeting Agenda Packet- Page 45 of 82
Page 7 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)
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 2022 Pollutants of Concern
Central San's pollutants of concern for 2022 comprised three groups of pollutants
as described below.
1. Priority Pollutants
Pollutants with effluent limits in Central San's 2017 and 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 2022 were:
Central San 2022 Pollution Prevention Annual Report Page 4
March 16, 2023 Regular Board Meeting Agenda Packet- Page 46 of 82
Page 8 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 2017/2022 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's watch list pollutant
for 2022 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 2022:
• Pesticides • Nonylphenol Ethoxylates
• Per- and Polyfluoroalkyl • Pharmaceuticals and
Substances (PFAS) personal-care products
• Nanoparticles Microplastics

Central San's 2023 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
