INTRODUCTION
This summary report of the Household Hazardous Waste (HHW) Program for fiscal year
(FY) 2023-24 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 2023-24, 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
annually. 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 26t" year of service in October
2023. The HHW Program serves all of central Contra Costa County, comprising 200,435
households with a population of approximately 518,835. Program participation for FY 2023-
24 was 15.8 percent (32,304 residential customers) across the service area, which is up from
14.9 percent in FY 2022-23. 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 0.39 percent in FY
2023-24 from 199,653 to 200,435. For perspective, the arithmetic mean of HHW participation
(count and percentage of total) and total households in the HHW service area for the previous
10 fiscal years was 32,513 customers, 16.61 percent participation, and 195,484 total
households, respectively.2
The HHW Collection Facility was open to the public and operational for 295 days during FY
2023-24. 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 June and December were the
inflection points of this cycle, again, with 3,059 and 1,639 customers served, respectively.
The reuse room was open during all operating days and was used by approximately 15,000
customers. Figure RP-1 shows monthly HHW program participation.
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 most customers dropping off waste at the end of the work week.
Throughout this report, FY 2018-19 figures are shown in charts to compare pre-COVID and post-
COVID years to help describe where participation, waste volumes, and other performance
indicators were prior to the pandemic.
2 A 10-year standard deviation of 2,364 customers, 1.31 percent HHW participation, and 2,960 total households was
calculated as well.

Figure RP-3 presents a comparison of the average number of participants 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 2023-24 showed an increase
to 109 participants per day from 102 participants per day in FY2022-23, but the previous 10-
10

year average was 114 participants per day with a standard deviation of seven. Although not
large gains, participation is headed back in an upward trend. A straw poll of several local
HHW programs also indicates a slight increase in participation over last year.

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 699 participants and collected 20,299 pounds of waste (not including
electronic waste) at a cost of $154,416 in FY 2023-24.
San Ramon's decrease in DTD participation follows a two-year trend; however, overall
participation in Central San's facility and DTD combined remained the same as last year. See
Figure RP-3 (Page 8) and Table SR-1 (page 11).

WASTE VOLUMES
In FY 2023-24, the HHW program collected 1,892,680 pounds of waste from residents and
small businesses. Of that total, 1,630,036 pounds of hazardous waste were recycled or
disposed of, while 262,644 pounds of reusable products were given to the public in FY 2023-
24. Compared to FY 2022-23, reusable products increased by about three percent, while the
total waste volumes collected also increased by three percent. However, compared to the
mean of the past 10 years of "Pounds of Waste per Participant" figures (63.8 pounds, including
the anomalies seen in fiscal years 2020-21 and 2021-22), FY 2023-24 would be 7.5 percent
lower than the mean.
As the trend shows in Figure WC-1, the amount of waste per participant is slowly decreasing.
It is primarily assumed that because most customers are repeat customers, they are simply
generating less waste or using the HHW facility more often.

On average, each customer processed by the HHW program during FY 2023-24 delivered 59
pounds of waste for disposal or reuse. This includes the 32,304 residents, 195 small business
appointments, and 55 retail partners that used the HHW collection facility during the fiscal year.
This represents a seven percent decrease from the previous fiscal year and approximately one
standard deviation from the 10-year average.'
3 A 10-Year mean and Standard Deviation were calculated to be 63.8 and 4.51 pounds respectively.

The wastes were either reused or transported from the HHW collection facility for recycling,
fuel blending, incineration, treatment, or landfill. Data specific to waste management activities
are presented on pages 14 and 15.
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. This report is included as Appendix I.
Figure WC-2 presents the quantity of wastes transported off -site each month for disposal. FY
2023-24 showed a three percent increase compared to FY 2022-23. 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.

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. There was only a fluctuation of one percent for flammables, poisons,
automotive products, and latex paint. For perspective, the one percent increase in latex paint
this year is equivalent to roughly 11 more gallons received per operating day for FY 2023-24.

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 7,700
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, button -cell batteries, and elemental mercury. In FY 2023-24, the HHW
program collected nearly 32 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, nearly 168,000 pounds of unwanted or
expired medications have been collected and properly disposed of by incineration. In FY 2023-
24, approximately 1,929 pounds were collected at the cost of $6,250. There has been a
consistent decline in the quantity 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 44 Med-Project collection sites, including the four
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 Iandfilled. The emphasis is on reduction, reuse, and
recycling whenever possible.
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 these management methods
divert wastes from being Iandfilled. The HHW program's progress toward sewer and landfill
diversion for FY 2023-24 is outlined below.
Reused
The reuse room was open each operating day in FY 2023-24. During this time, 13.9 percent
(262,644 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 $121,000 in disposal costs.
Recycled
The waste recycled at off -site facilities includes latex paint, used motor oil/filters, antifreeze,
car batteries, propane cylinders, fluorescent lamps, LED lamps, lead (scrap metal), mercury,
household batteries, printer cartridges, Freon, mercury thermostats, fire extinguishers, and
even home -generated cooking oil. Many of these recyclable waste streams are free, or we
receive rebates for recycling.
Fuel Blended (Waste Derived Fuel)
In FY 2023-24, 338,714 pounds of oil -based paint and fuels (gasoline, paint thinners, etc.)
were 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 landfills.

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 Program disposal rates.
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 yearly, 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 3.3
percent of the total residential participants during FY 2023-24 were first-time customers, and
the remaining 96.7 percent were repeat customers.
23
December 5, 2024 Regular Board Meeting Agenda Packet - Page 230 of 274
Page 26 of 52
REVENUE AND EXPENSES
The HHW program expenses for FY 2023-24 were $3,342,731, or 4.6 percent more than last
year. The increase is primarily due to labor costs (District and contract) increasing by 10.8
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. Although
it appears the backlog has been reduced enough to return costs to levels before August 2021,
they have not. It appears that the current elevated costs are now the new standard.
Beginning in FY 2022-23, we are focusing on the cost per household rather than the cost per
participant, as the cost per household represents what Central San customers pay as part of
their sewer service charge. For the first 24 years of operation, we reported the cost per
participant 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 participant that is not charged to our customers and
a cost our customers would not likely pay to use the service if required. It will remain in the
report for historical purposes only.
For FY 2023-24, the cost per household was $16.68. This means that $16.68 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 296 days. This cost per
household is slightly more than last year's $16.00 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.
Revenue, Savings, and No Cost Waste Management
Revenue for the HHW Collection Facility included payments from other jurisdictions under service
agreements (MVSD, City of Concord, City of Clayton, and City of San Ramon) and charges to
24
December 5, 2024 Regular Board Meeting Agenda Packet - Page 231 of 274
Page 27 of 52
small businesses under the Small Business Program. Also, staff is diligent in seeking low-cost or
no -cost management or revenue -generating alternatives while keeping safe and proper disposal
in mind. Many of the wastes collected by the HHW facility have market value or require
manufacturers to manage and pay the cost of their recycling, also known as Extended Producer
Responsibility (EPR). Table RE-1 describes the revenue -generating or no -cost waste streams
that were collected in FY 2023-24 and the savings or rebates provided to Central San.

divided by the number of pounds disposed ($0.39/lb. for '23-24), multiplied by the number of pounds of PaintCare waste
recycled and other reusable products. This is a conservative estimate and does not include labor or other factors.
** Sale of collected materials or no -cost recycling — Savings/rebate equals "Sale of collected materials and small
business revenue" minus PaintCare reuse rebate and Small Business Program revenue. Pounds collected is total of
car batteries, cooking oil, rechargeable batteries, Li -ion batteries, printer cartridges, lead, mercury thermostats, and
freon. The savings shown includes the cost to dispose (at $0.39/lb.) and any rebates provided.
