Note: On- and off-site releases is defined as the amount of toxic
chemical releases on-site (to air, water, underground injection,
landfills and other land disposal), and the amount transferred
off-site for disposal. Chart a shows lead releases (in pounds) for
the top industries, excluding hazardous waste refuse systems.
Releases from hazardous waste refuse systems are shown in
millions of pounds in chart b. Charts a and b show combined
totals for the entire region, AZ, CA, HI, NV, and the Pacific

lead releases (in pounds).

The 2001 Data for Lead
EPA has just made public the 2001 data on toxic
chemicals that were released* to the air, water and land
within the Pacific Southwest region. This information
comes from the Toxics Release Inventory (TRI), a
federal community right-to-know program.
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.
For the year 2001, lead and lead compounds were
reported as persistent, bioaccumulative and toxic
(PBT) chemicals for the first time. While 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.
*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.

A Note on Risk
It is important to note that releases 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 the case of lead, the TRI data does not
indicate whether a facility is violating environmental
laws. The majority of the major industrial sources of
lead and are subject to strict controls.
Industries
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. These sectors are metal and coal mining,
electricity generation, commercial hazardous waste
treatment, solvent recovery, petroleum bulk terminals,
and wholesale chemical distributors.
Releases
In a state-by-state comparison California, Arizona,
Nevada and Hawaii ranked 1, 32, 43, and 23 ,
respectively for total on- and off-site releases of lead.

Reporting Industry Sectors-the 2001 Data
A review of the TRI data suggests that among the TRI-
regulated industry sectors, hazardous waste refuse
systems is the largest contributor of lead releases in the
Region. This industry sector accounts for 91% of the
Region 9 total. Federal facilities and nonferrous
foundries are also large contributors.

Hazardous Waste Refuse Systems
This industry includes hazardous waste treatment and
disposal and material recovery facilities.
Four hazardous waste treatment facilities reported
disposing 5.8 million pounds of lead into on-site
landfills.
Federal Facilities
Many federal facilities meet the reporting
requirements of the Toxic Release Inventory. The
majority of facilities that reported lead releases are
U.S. Army, Navy, Marines, and Air Force facilities.
Of these, most are firing ranges and weapons testing
facilities. In Region 9, twenty-one federal facilities
reported over 184 thousand pounds of on- and off-site
lead releases, with the U.S. Army Schofield Barracks
Range accounting for over 58 thousand pounds
released on-site.
Nonferrous Foundries
This industry is made up of establishments primarily
engaged in manufacturing nonferrous metal castings
(including alloys), except die-castings and other
castings of aluminum or copper. Lead may be a trace
constituent in scrap metal and alloys, which is used in
steelmaking, in electro metallurgical products, and at
iron or steel foundries,. Of the six facilities that
reported in Region 9, P. Kay Metal Supply reported

almost all of the 129 thousand pounds of on- and off-
site lead releases.
Electricity Generating Facilities
In this industry, lead can be formed as unwanted
byproducts during the combustion process. Only
facilities that combust coal or oil to generate electricity
for distribution in commerce are required to report to
the Toxics Release Inventory. In Region 9, three
electricity generating facilities reported 78 thousand
pounds of on- and off-site lead releases, most of which
were released to land.
