INTRODUCTION
This summary report of the Household Hazardous Waste (HHW) Program for fiscal year (FY)
2021/22 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 2021/22, 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 wastes 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 plants
are operating at peak efficiency and eliminates chemical wastes from flowing through
treatment processes that are designed specifically for human waste.

RESIDENTIAL PARTICIPATION
The HHW Collection Program is completing its 25th year of operation. The HHW Program
serves all central Contra Costa County, which is comprised of 198,619 households with a
population of approximately 517,600. Program participation has increased steadily from the
7.8 percent of households served during the opening year in FY 1997/98 to as much as 18.4
percent in FY 2018/19. In FY 2019/20, that figure fell to 14.0 percent due to the three-month
closure from March 16 to June 15, 2020, during the COVID-19 pandemic. Participation
rebounded in FY 2020/21 to 17.9 percent while having record participation in September and
October. FY 2021/22 showed a decrease in HHW participation of 5.6 percent (35,348 to
33,376 customers) and an increase in total occupied households within the service area of
1.6 percent (195,540 to 198,619 households)when compared to the previous fiscal year. 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 31,856
customer, 16.52 percent participation, and 192,445 total households, respectively.2
The HHW Collection Facility was open to the public and operational for 293 days during
FY2021/22, with only one unscheduled shutdown (3.5 days) due to COVID-19 in May 2022.
Seasonal participation patterns appear to have resumed, 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, with 3,446 and 1,641 customers served, respectively. The reuse room was open during
all operating days and was used by approximately 14,000 customers. Figure RP-1 shows
HHW program participation monthly.
2 A ten-year standard deviation of 2,652 customers, 1.32 percent HHW participation, and 2,318 total households was
calculated as well.

Figure RP-2 presents the average residential participation for each day of operation, Monday
through Saturday. Average cars per workday decreased from the prior fiscal year, which had
record numbers coming out of the pandemic-caused facility closure but appears to be
returning to previous averages, with the bulk of customers dropping off waste at the end of
the work week, as shown in Figure RP-2.

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 2021/22 showed a slight
decrease to 114 cars per day from 124 cars per day in FY 2020/21, but the previous ten-
year average (including FY 2019/20) was 110 cars per day with a standard deviation of 9.

includes a-waste pickups.
3 Hazardous wastes from outside of the service area were accepted and processed for one of two reasons: 1)
employees from Central San and MVSD who live outside of the service area are also eligible for HHW program
participation, or 2) household hazardous waste generated outside the service area that is deemed unsafe for
further transport is accepted and processed as a safe and responsible business practice.

SAN RAMON DOOR-TO-DOOR COLLECTION PROGRAM
Since 2011, when the City of San Ramon elected to sponsor its own Door-to-Door (DTD)
HHW collection program, we have tracked their usage with the HHW facility's 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's DTD program
was on hiatus during the pandemic, and data for FY 2018/19 was not provided to the District;
therefore FY 2017/18 was used as a comparison in Table SR-1.
San Ramon reported their DTD program served 1,089 participants and collected a total of
62,023 pounds of waste (6,980 pounds were electronic waste) at the cost of $186,551 in FY
2021/22. Since Central San's program does not accept e-waste, it was subtracted in Table
SR-1 below; however, all participants are assumed to have had both e-waste and HHW
picked up. The costs will also remain, as those are fixed costs for each resident.

WASTE VOLUMES
In FY 2021/22, the HHW program collected 2,187,767 pounds of waste from residents and
small businesses. Of that total, 1,942,652 pounds of hazardous waste was recycled or
disposed of, while 244,978 pounds of reusable products were given away to the public in FY
2021/22. Compared to FY 2020/21, this is a 28 percent decrease in weight processed by the
HHW facility. However, if the previous two fiscal years are excluded and considered
anomalous, then FY 2021/22 would be a 5.6 percent increase compared to operations in the
pre-pandemic era. (See Table WC-1).

On average, each customer processed by the HHW program during FY 2021/22 delivered 65
pounds of waste for disposal or reuse. This includes the 33,376 residents, 209 small
businesses, and 73 retail partners that used the HHW collection facility during the fiscal year.
This is a 14 percent decrease from FY 2020-21 (76 pounds/vehicle) and a near-even break
with the running 10-year average of 65.4 pounds.3
The wastes were transported from the HHW collection facility for reuse, recycling, fuel
blending, incineration, treatment, or landfill. Data specific to waste management activities is
presented on pages 10 through 14.

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 in Appendix I.
Figure WC-2 presents the quantity of wastes transported off-site each month for disposal. FY
2021/22 did not show the same record-breaking waste volumes seen in FY 2020/21;
however, it is worth noting that 8 of the 12 months showed disposal weights above the 5-year
average. In the past four years shown in Figure WC-2, FY 2021/22 and FY 2018/19 are the
two most recent full years where the reuse room was open and operational, which is partly
the reason for decreased disposal volumes during those two periods and the increased
volumes in the intermediate years. Note: March-June 2020 disposal numbers were below
the average due to the three-month COVID-19 shelter-in-place order.

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 2021/22, the HHW program collected
an estimated 58 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 be a threat to our
bay, 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
either 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 average cost per pound variation is caused by the amount of packaging (jars, 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 154,000 pounds of unwanted or
expired medications have been collected and properly disposed of by incineration. In FY
2021/22, approximately 5,400 pounds were collected at the cost of$19,750. 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 the Contra Costa County Safe Disposal Ordinance (CCCSDO). As of the
printing of this report, there are more than 40 CCSDDO and Central San sites in the HHW
service area. By the end of FY 2021/22, only seven of the original 13 Central San collection
locations remained part of our program, as three sites converted to CCCSDO during the year.
The following sites were converted to CCCSDO as of the listed dates:
San Ramon - November 2019 Orinda - July 2021
Clayton - June 2021 Pleasant Hill - December 2021
Concord - June 2021 Moraga - April 2022

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) and 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 closed for approximately 15 months during the COVID-19 pandemic and
reopened in the last two weeks of FY 2020/21. By being open all of FY 2021/22, we were
able to give away 11.2 percent (244,978 lbs.) of the total amount of waste collected by the
HHW program. The reuse program saved approximately $98,000 in disposal costs.
Recycled
The types of waste recycled at off-site facilities include 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 FY2021/22, a total of 415,994 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
quantities of waste diverted from landfill.

SMALL BUSINESS PROGRAM
An important 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), formerly "Conditionally Exempt Small Quantity Generator"
(CESQG). In August 2021, AB698 was signed into law, and as a result, the State regulations
unified with Federal regulations renaming "CESQG" to "VSQG." This Small Business
Program remains a cost-effective and convenient hazardous waste disposal option for small
generators of hazardous waste. 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 yearly, as does the revenue collected. See Appendix III for the current CESQG
(VSQG) 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. Itis publicized
in each issue of the Central San Pipeline newsletter, which is 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 6.1 percent of the total residential participants during FY 2021/22 were first-
time customers, and the remaining 93.9 percent were repeat customers.

REVENUE AND EXPENSES
The HHW program expenses for FY 2021/22 of$2,976,567 decreased by almost 12 percent
compared to FY 2020/21. This was primarily due to the recovery of pandemic-related surges
in participation and waste volumes and reopening of the Reuse Room. The results were a 6
percent decrease in the number of customers served, a 13 percent decrease in the average
amount of waste per vehicle served, and a fully operational Reuse Room program (which
supplemented a 28 percent reduction of waste shipped for treatment or disposal during the
year). For perspective, expenses in FY 2021/22 were only 6 percent higher when compared
to pre-pandemic FY 2018-19.
The effects of the pandemic continue to linger in the hazardous waste management market,
as shutdowns, backlogs, and labor issues plague incinerators, fuel blenders, and other end-
of-disposal processes. In August 2021, US EPA issued a notice explaining the nationwide
problem and warned that 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, saying that the backlog remains in effect.
The backlog caused our hazardous waste contractor to be unable to manage our wastes that
require fuel recovery or destructive incineration. This required staff to quickly shift to a
secondary contractor who was able to properly manage our waste on a continuous basis.
This short-term contract was very important in keeping wastes properly flowing through the
HHW facility. Rates for the new contractor's services were at or below our previous contract
pricing.
The supply chain has also been affected by the labor market as containers, and other
packaging materials were difficult to find in needed quantities. Also, a long-term supplier was
purchased by a competitor, which reduced the number of local outlets, limiting options.
The operating cost per car decreased from $95 per car in FY 2020/21 to $88 per car in FY
2021/22. This number remains higher than normal when compared to pre-pandemic
FY2018/19, at $78 per car. Costs for future years are expected to remain high and will likely
increase even as constraints from the pandemic decrease and supply chains stabilize.
Figure RE-1 shows the operating cost per car(participant) since the inception of the program.

Amortization of Capital Expenditures
Amortization of Capital Expenditures is derived from the capital costs to build the collection
facility and all capital improvements amortized over 30 years. No capital expenditures were
added to the facility in FY 2021/22. Table RE-2 shows the amortization schedule of all capital
expenditures since the completion of the HHW facility in 1997.
