Note: In order to directly compare 1999, 2000 and 2001 releases, FBI and lead/lead compound chemical reported releases are
illustrated separately in the charts above.
The 2001 Public Data Release
EPA has just made public the 2001 data on toxic
chemicals that were released to California's air, water
and land. This information comes from the Toxics
Release Inventory (TRI), a federal community right-to-
know program. In California, 1619 facilities reported a
total of 60.7 million pounds of toxic chemical releases*.
It is important to note that release should not be
directly equated with risk. To evaluate risk, release
data must be combined with information about
chemical toxicity, site-specific conditions, and
exposure. In addition, these data do not indicate
whether a facility is violating environmental laws.
Many of the substances reported through this program
are subject to state and federal regulations designed to
protect human health and the environment.
Industries
* Release is defined as the amount of a toxic chemical released on-site (to air, water, underground injection, landfills and
other land disposal), and the amount transferred off-site for disposal. Year to year data comparisons do not reflect changes
in reporting requirements.

-------
California Toxics Release Inventory Fact Sheet
Manufacturing industries have been reporting their
releases since 1987, and federal facilities started
reporting in 1994. In 1998, an additional seven
industry sectors began reporting their toxic chemical
releases for the first time. These sectors are metal and
coal mining, electricity generation, commercial
hazardous waste treatment, solvent recovery, petroleum
bulk terminals, and wholesale chemical distributors.
Releases
California's total reported on- and off-site releases
decreased 22% when compared to 2000 data. Leading
the trend was a decrease of 6.3 million pounds in
reported on-site land disposal, an 18% change. This is
due primarily to a decrease in waste from toxic cleanup
projects disposed at the Chemical Waste Management
Inc. facility in Kettleman City.
Also contributing to the state trend was a reported
decrease in transfers off-site for disposal, down 45%
from the previous year. This was due in large part to
decreased waste handling at DK Environmental in
Vernon.
Reported releases to water and air also decreased from
2000 levels, by 19% and 16% respectively. Much of the
decrease in releases to water was due to reduced
discharges at the Samoa Pulp Mill in Humboldt County
and the Chevron Refinery in El Segundo. Underground
injection releases reported have increased by 15%.
Table of PBT Releases in California
June 2003
Much of this increase is attributable to three refineries
in Bakersfield (San Joaquin Refining Co., Equilon
Enterprises L.L.C., and Equilon Bakersfield Refinery
Areas 1 & 2).
Persistent. Bioaccumulative. and Toxic Chemicals
In the year 2000, TRI was expanded to include
additional persistent, bioaccumulative and toxic
(PBT) chemicals, and required reporting for these
chemicals at lower thresholds, ranging from 0.1 grams
to 100 pounds. PBT pollutants are toxic chemicals
that persist in the environment and bioaccumulate in
food chains, thus posing risks to human health and
ecosystems.
In California,7.4 million pounds of total on- and off-
site releases of PBT chemicals were reported.
Below is a table of the PBT releases in California
ranked by total on- and off-site releases. The data is
in pounds for all chemicals except dioxin, which is
given in grams.
New Data - Lead and Lead Compounds
For the year 2001, lead and lead compounds were
reported as persistent, bioaccumulative and toxic
(PBT) chemicals for the first time. While lead and
lead compounds have been on the list of reportable
chemicals since 1987, for the year 2001 the reporting
threshold was drastically lowered (to 100 pounds
manufactured, processed, or otherwise used), and this
change has resulted in more comprehensive release
information for these compounds.

California Toxics Release Inventory Fact Sheet
Nearly 7.3 million pounds of total on- and off-site
releases of lead and lead compounds were reported
in California. Many of the top releasing facilities
are in the refuse systems/sanitary services
industry, mining industry, or are federal
facilities. Much of the lead reported released to
land (approximately 5.8 million pounds) was by
Chemical Waste Management Inc., in Kettleman
City.
Mercury and Mercury Compounds
Much of the mercury and mercury compounds
reported was released to land (approximately 34,000
pounds) by mining facilities. Hazardous waste
management facilities reported a significant amount
(greater than 16,000 pounds) disposed on-site or
transferred off-site for disposal. The largest share of
air emissions, over 4,800 pounds, came from the
Portland cement manufacturing sector. Petroleum
refineries reported nearly 700 pounds of mercury
and mercury compounds to the air.
Polvchlorinated biphenvls (PCBs) and
Polvcvclic Aromatic Compounds (PACs)
Most of the reported PCBs were disposed of in an
on-site hazardous waste landfill at Chemical Waste
Management Inc. in Kettleman City (approximately
16,000 pounds). Hazardous waste treatment
facilities reported releasing the most PACs, over
28,000 pounds.
Dioxin
For dioxin and dioxin-like compounds, much of the
reported releases are attributable to the secondary
smelting and refining of nonferrous.
