INTRODUCTION
This summary report of the Household Hazardous Waste (HHW) Program for fiscal year
(FY) 2022/23 presents the program participation levels, an analysis of the hazardous waste
delivered to the facility, and the costs associated with the program. The program's high level
of participation and the amount of hazardous waste collected and properly managed each
year demonstrate the benefits to both public health and the environment.
Background
In 1995, it was recognized and resolved by all central Contra Costa County cities', the
Central Contra Costa Solid Waste Authority, Central Contra Costa Sanitary District (Central
San), and co-sponsor Mt. View Sanitary District (MVSD) that mobile HHW collection
events were not efficient or convenient, and that a permanent HHW Collection Facility
(HHWCF) was needed. In 1997, Central San opened the first permanent HHW Facility in
Contra Costa County with its service agreement partners MVSD and the cities of Clayton,
Concord, and San Ramon.
Pollution Prevention
Central San's core function is to operate a municipal wastewater collection system and a
53.8-million-gallons-per-day-rated treatment plant (plant). The wastewater collection system
covers 145 square miles and includes approximately 1,500 miles of sewer pipes. In
FY 2022/23, the plant treated nearly 12 billion gallons of wastewater.
MVSD's plant serves an estimated population of 21,900, with approximately 270 businesses
in its 4.7 square mile service area, which is served by 73 miles of sewer collection system.
MVSD reclaims approximately 450 million gallons of water for 21 acres of wetland habitat
every year. Both Central San's and MVSD's plants are designed to treat and prevent
biological waste from entering our waterways. However, chemicals must be removed prior
to entering the plant to keep the biological treatment train healthy. This is how HHW
collection benefits Central San and MVSD. Pollution prevention at the source ensures that
our plant operates at peak efficiency and eliminates chemical wastes from flowing through
treatment processes designed specifically for human waste.

RESIDENTIAL PARTICIPATION
The HHW Collection Program celebrated the completion of its 25t" year of service in October
2022. The HHW Program serves all central Contra Costa County, comprising 199,653
households with a population of approximately 523,000. Program participation for FY 2022/23
was 14.9 percent (30,074 residential customers) across the service area, which is down from
16.8 percent in FY 2021/22. The 11 percent decrease in participation rate is assumed to be
partly due to a longer and wetter than average winter. Also, participation has not returned
fully to pre-pandemic levels since peaking at 18.4 percent in FY 2018/19, then falling to 14.0
percent due to the three-month closure in 2020, during the beginning of the pandemic.
Total occupied households within the service area modestly increased by 0.5 percent in
FY2022/23 from 198,619 to 199,653. For perspective, the arithmetic mean of HHW
participation (count and percentage of total) and total households in the HHW service area
for the previous ten fiscal years was 32,320 customers, 16.66 percent participation, and
193,420 total households, respectively.2
The HHW Collection Facility was open to the public and operational for 295 days during
FY2022/23. Seasonal participation patterns returned to their historical norms, with our highest
participation occurring in the summer, then tapering off into fall and winter and steadily
increasing from the new year into the spring. The months of July and December were the
inflection points of this cycle, again, with 3,222 and 1,349 customers served, respectively.
The reuse room was open during all operating days and was used by approximately 14,000
customers. Figure RP-1 shows monthly HHW Program participation.
2 A ten-year standard deviation of 2,696 customers, 1.33 percent HHW participation, and 2,780 total households was
calculated as well.

Figure RP-2 presents the average residential participation for each day of operation, Monday
through Saturday. Participation throughout the week continued to resemble previous
averages, with the bulk of customers dropping off waste at the end of the work week. Also
shown in RP-2 are the results for fiscal years 2018/19 and 2022/23, which represent the last
pre-pandemic (baseline) year and the current year.

Figure RP-3 presents a comparison of the average number of cars per operating day since
the HHW Facility opened. This data serves as a tool for planning staffing levels through the
different seasons and promoting the facility's services. FY 2022/23 showed a decrease to
102 cars per day from 114 cars per day in FY 2021/22, but the previous ten-year average
was 113 cars per day with a standard deviation of 8.
According to Cal Recycle, HHW Programs in California saw a 14 percent decrease in
permanent HHW Facility participation when compared to last year. Considering the
numerous impacts on our lives over the last three years, there are several ways to
speculate why participation has not rebounded back to pre-pandemic levels and if we
should even expect them to return to that level.
• People are out and about, not thinking about cleaning the garage.
• Weather— record rain events kept most people indoors for the winter and spring.
• The economy — customers may have calculated to stretch their household products
longer and save them for a little longer because of the inflated cost of replacement.
• It's too expensive to start home improvement projects. Building material prices and
loans to pay for them are too high.
• The "California Exodus," which should bring additional participation because most
people do not take household chemicals with them, has not noticeably affected
participation. In fact, the number of occupied households in the HHW service area
increased by one-half percent.

SAN RAMON DOOR-TO-DOOR COLLECTION PROGRAM
Since 2011, when the City of San Ramon elected to sponsor their own Door-to-Door (DTD)
HHW collection program, we have tracked their usage with the HHW Facility to show overall
participation and proper waste management within the Central San service area. Table SR-
1 below describes the participation, waste volumes, and cost that San Ramon reported,
compared to the HHW facility's usage figures for San Ramon. San Ramon reported their DTD
program served 747 participants and collected a total of 26,929 pounds of waste (not
including electronic waste) at a cost of $156,991.52 in FY 2022/23.
San Ramon's decrease in DTD participation follows a similar trend to that of Central San's
HHW Program and others in California have experienced in FY 2022/23. See Figure RP-3
(Page 8) and Table SR-1 below.

WASTE VOLUMES
In FY 2022/23, the HHW Program collected 1,838,347 pounds of waste from residents and
small businesses. Of that total, 1,583,854 pounds3 of hazardous waste were recycled or
disposed of, while 254,493 pounds of reusable products were given to the public in FY
2022/23. Compared to FY 2021/22, the amount of reusable products increased by about 4
percent, while total waste volumes collected decreased by 18 percent. However, if fiscal years
2020/21 and 2021/22 are excluded and considered anomalous, FY 2022/23 would only be a
13 percent decrease compared to operations in pre-pandemic FY 2018/19. (See Table WC-1
for a breakdown by city).

On average, each customer processed by the HHW Program during FY 2022/23 delivered 61
pounds of waste for disposal or reuse. This includes the 30,074 residents, 191 small business
appointments, and 62 retail partners that used the HHW Collection Facility during the fiscal
year. This represents a 6 percent decrease from the previous fiscal year and approximately
one standard deviation from the 10-year average.4
The wastes were either reused or transported from the HHW Collection Facility for recycling,
3 An arithmetic mean and standard deviation were calculated for the previous 5 years and found to be 1,959,154
Pounds and 412,141 Pounds, respectively.
4 A 10-Year mean and Standard Deviation were calculated to be 65.2 and 4.06 pounds respectively.

fuel blending, incineration, treatment, or landfill. Data specific to waste management activities
are presented on pages 13 through 16.
The California Department of Resources Recycling and Recovery (CalRecycle) requires a
Form 303 report each fiscal year (July through June) summarizing the quantity and types of
hazardous waste processed and a breakdown of the waste management method for each type
of hazardous waste collected, it is included as Appendix I.
Figure WC-2 presents the quantity of wastes transported off-site each month for disposal. FY
2022/23 showed an 18 percent decrease compared to FY 2021/22, with all but two months
reporting waste volumes less than the previous year. Comparison to preceding years yields
inconclusive inferences as the Reuse Room was shut down for a majority of FY 2019/20 and
FY 2020/21, which led to increased waste disposal for the facility. Again, this may simply be a
rebounding effect in the wake of the COVID-19 orders being rescinded and the public returning
to a previously "normal" way of life. A plateau of waste volumes and vehicles served in
succeeding years may infer a new "normal" for the facility's customer base. An inflection point
and increase in the same values may show a return to pre-pandemic trends. Additional
datasets from succeeding years are needed for an answer with certainty to be reached.

Figure WC-3 presents a breakdown of hazardous wastes processed by type of waste. The
transportation classifications on the shipping documents were used as the primary means for
segregation into waste types, except for "Automotive Products," which was used to represent

the facility's Motor Oil, Oil Filter, Antifreeze, and Lead Acid Battery waste streams. Compared
to the previous fiscal year, there were no significant changes to the proportional weight for any
specific category. Flammables, Corrosives/Oxidizers, and Other waste streams remained
constant year over year. Poisons, Fluorescent Lamps + Batteries, and Automotive Products
saw increases between 1-2%, while Aerosols and Latex Paint decreased 1% and 4%
respectively. For perspective, the 4% decrease in Latex Paint this year is equivalent to -10
fewer gallons received per operating day for FY 2022/23.

POLLUTION PREVENTION EFFORTS
Central San's Pollution Prevention (P2) program has evolved over the years to become an
important component of our mission, which specifically includes P2 and reflects the growing
importance of P2 for regulatory compliance. Central San is required to monitor and prevent
certain pollutants from entering the influent wastewater. The HHW program helps prevent
waste from reaching the sewer and tracks the amount diverted from the system.
Mercury Collection Program
The HHW Program facilitates Central San's promotion of proper mercury disposal by
accepting all types of mercury, including elemental mercury, mercury-containing devices (e.g.,
fluorescent bulbs, batteries, mercury switches, and mercury thermometers), and mercury-
containing compounds (paints and pesticides containing mercury).
Since the beginning of the mercury thermometer exchange program in 1999, more than 7,200
mercury thermometers have been collected and exchanged for non-mercury types. Table PP-
1 describes the types of mercury-containing wastes tracked by HHW staff. This system closely
estimates the quantities of mercury contained in fluorescent lamps, thermometers,
thermostats, switches, and button-cell batteries. In FY 2022/23, the HHW Program collected
an estimated 47 pounds of elemental mercury contained in these types of wastes.

Pharmaceutical Collection Program
Another way the HHW Program contributes to Central San's P2 program is by collecting
unwanted or expired pharmaceuticals from residents. Pharmaceuticals can threaten our bays,
rivers, and creeks as some of the compounds they contain cannot be entirely treated or
removed by wastewater treatment plants. Pharmaceuticals can enter the sewer system by
excretion from the body or customers dumping them down the drain. Since we cannot prevent
unmetabolized medications from entering the treatment plant, we established a collection and
disposal program for unwanted pharmaceuticals.
Table PP-3 describes the amount of pharmaceuticals collected by each site and the cost of
collection and disposal during the year.

*The variation in the average cost per pound is caused by the amount of packaging Oars,paper,cardboard,etc.)included
in the collection bins. Bags for consolidating pills are offered at most collection sites but are not often used.The fullness
of the container when it is picked up also affects the cost/lb.
Since the pharmaceutical program began in 2009, over 165,000 pounds of unwanted or
expired medications have been collected and properly disposed of by incineration. In FY
2022/23, approximately 5,660 pounds were collected at the cost of$21,200. There has been
a consistent decline in the amount of medications collected by our pharmaceutical program
primarily because of the increased number of collection locations in the HHW service area
associated with Med-Project, the state-required manufacturer-sponsored pharmaceutical
collection program. There are more than 40 Med-Project collection sites, including the six
remaining Central San sites in the HHW service area.

WASTES DIVERTED FROM SEWER AND LANDFILL DISPOSAL
The California Integrated Waste Management Act of 1989 (AB 939) requires the diversion of
HHW from the municipal solid waste stream. AB 939 establishes a waste management
hierarchy to minimize the amount of HHW sent to landfills through reduction, reuse, recycling,
treatment, or incineration (fuel blending or destructive incineration). It diverts a minimum of
50 percent of solid waste from being landfilled. The emphasis is on reduction, reuse, and
recycling whenever possible.
As a water quality agency, diverting hazardous waste from the sewers and storm drains is
equally important. Although Central San's HHW Program is not required to comply with AB
939, Central San's waste management strategy mirrors AB 939 by prioritizing reduction,
reuse, recycling, and fuel blending, in that order, to the greatest extent feasible. All of which
divert these wastes from being landfilled. The HHW Program's progress toward sewer and
landfill diversion for FY 2021/22 is outlined below.
Reused
The reuse room was open each operating day in FY 2022/23. During this time, 13.8%
(254,493 lbs.) of the waste received was diverted to the reuse program and returned to the
public because it was still a viable/usable product. As a result, the reuse program saved
approximately $105,000 in disposal costs. This savings is an approximate 4% increase, by
weight, from the previous fiscal year.
Recycled
The waste recycled at off-site facilities includes latex paint, used motor oil/filters, antifreeze,
car batteries, propane cylinders, fluorescent lamps, lead (scrap metal), mercury, household
batteries, printer cartridges, and even home-generated cooking oil. Many of these recyclable
waste streams are rebated or free for recycling.
Fuel Blended (Waste Derived Fuel)
In FY2022/23, a total of 347,281 pounds of oil-based paint and fuels (gasoline, paint thinners,
etc.)was blended with other flammable hazardous wastes and used as a fuel source to make
Portland cement. While fuel blending is lower in the waste management hierarchy than
recycling, it is still a beneficial use that avoids using fossil fuels and prevents destructive
incineration, treatment, or Class I landfill disposal. Table WD-1 shows the waste streams and

SMALL BUSINESS PROGRAM
An essential component of the HHW Program is the collection of hazardous wastes from
small businesses. These businesses must meet the regulatory standards as a "Very Small
Quantity Generator" (VSQG). This Small Business Program remains a cost-effective and
convenient disposal option for small hazardous waste generators. Program statistics are in
tables SB-1 and SB-2.
Revenue collected from small businesses is for hazardous waste disposal or recycling only
and includes an administration fee of $20 per appointment. Small business participation
fluctuates from year to year, as does the revenue collected. See Appendix III for the current
Small Business disposal charges.
Small Business Program outreach includes ongoing advertising in local chamber of
commerce publications, Central San's Pipeline newsletter, MVSD's Mt. View Monitor
newsletter, and business trade fairs. Central San's Environmental Compliance Inspectors
and Contra Costa County Hazmat Program Inspectors also share the opportunity while
completing their fieldwork and onsite audits of the operations of eligible businesses.

PUBLIC EDUCATION AND OUTREACH
HHW Program participation has grown steadily since the first year of operation. It is
publicized in each Central San Pipeline newsletter issue, mailed twice a year to more than
156,000 Central San residential and business customers. Additionally, MVSD, the Central
Contra Costa Solid Waste Authority, and cities and organizations in the service area have
used social media and newsletters to provide public education and promotion of the HHW
Program and its associated Pharmaceutical Disposal Program. With this promotional
strategy, about 3.6 23
November 16, 2023 Regular Board Meeting Agenda Packet- Page 117 of 175
Page 26 of 51
percent of the total residential participants during FY 2022/23 were first-time customers, and
the remaining 96.4 percent were repeat customers.
REVENUE AND EXPENSES
The HHW Program expenses for FY 2022/23 were $3,194,983, or 7.3 percent more than
last year. The increase is primarily due to District labor costs increasing by 6.6 percent and
our waste services contract, which increased the incremental costs for waste disposal,
contract labor, and related supplies by more than 30 percent. Contract labor costs rose
considerably when prevailing wages were found to be required for non-"trade" positions
performing work for most water-related special districts.
Waste disposal costs have remained high since August 2021, when US EPA issued a notice
explaining a nationwide backlog and warned the hazardous waste disposal market was under
stress and was not expected to recover until the summer of 2022. US EPA extended that
warning in May 2022 and again in July 2023, saying the backlog remains in effect. There is
no timeframe for when the backlog will be cleared; however, we have started to see some
signs that the lingering issues have started to ease.
Beginning this year, we are focusing on the cost per household rather than the cost per car,
as the cost per household represents what Central San customers pay as part of their sewer
service charge. For the past 25 years, we've reported the cost per car as the gauge to value
our customers' expenses, but it only represents what it would cost if each HHW customer
had to pay at the time of service. It is unreasonable to continue to report a cost of $80-100
per car that is not actually charged to our customers. It will remain in the report for historical
purposes only.
For FY 2022/23, the cost per household was $16.00. This means that $16.00 of each
annual sewer service charge allowed residents unlimited access to the HHW Facility, Reuse
Room, Pharmaceutical Collection Program, and the residential Recycled Water Fill Station.
All were open and available seven hours a day, six days per week, and for 295 days. This
cost per household is slightly more than FY 2021/22's $14.99 per household due to the cost
increases mentioned previously. Although not included in the cost of the HHW Program, the
Residential Recycled Water Fill Station is conveniently positioned at the HHW Facility, and
its operation and staff are overseen by HHW staff.
