2019 POLLUTION PREVENTION ANNUAL REPORT
I. 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

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

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

E. 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.
