What is the Toxics Release Inventory?

The Toxics Release Inventory (TRI) is a database
containing detailed information  on nearly
650 chemicals and chemical categories
that over 23,000 industrial and other
facilities manage through disposal
or other releases, recycling, en-
ergy  recovery,  or  treatment
(see Figure l).The data are
collected  from  industries
including manufacturing,
metal and coal  mining,
electric  utilities,  com-
mercial hazardous waste
treatment,  and   other
industrial sectors.

Section   313  of  the
Emergency   Planning
and Community  Right
to Know Act (EPCRA)
of 1986  was enacted to
facilitate  emergency plan-
ning, to minimize the effects
of potential toxic chemical ac-
cidents, and to provide the pub-
lic with information on releases of
toxic  chemicals in  their communi-
ties. The Pollution Prevention Act (PPA)
of 1990 mandates collection of data on toxic
chemicals treated on-site, recycled, and combusted
for energy recovery. Together, these laws require facilities in
certain industries, which manufacture, process, or use toxic chemicals above specified amounts, to report an-
nually on disposal or other releases and other waste management activities related to these chemicals.

The U.S. Environmental Protection Agency (EPA) maintains this information in a national database called the
Toxics Release Inventory, which is available to the public via the Internet (www.epa.gov/tri).
                                                       'Publidy-OwnedTreatmunt Works
What are the benefits of TRI data?
The TRI provides the public with unprecedented access to information about toxic chemical releases and
other waste management activities on a local, state, regional, and national level.

TRI data help the public, government officials and industry:
 identify potential concerns and gain a better understanding of potential risks;
 identify priorities and opportunities to work with industry and government to reduce toxic chemical
  disposal or other releases and potential risks associated with them; and
 establish reduction targets and measure  progress toward reduction goals.

TRI data are widely used across EPA programs. For example, the National Partnership for Environmental
Priorities, an element of the Resource Conservation Challenge (RCC), uses TRI  data to identify facilities
that may present pollution prevention opportunities. EPA also uses TRI data in the Risk Screening Environ-
mental Indicators  (RSEI)  tool, which provides users with additional understanding of chronic human health
and potential exposures associated with TRI chemicals.You can search for other EPA programs and tools that
utilize TRI data by visiting EPA's Web site at  www.epa.gov or from EPA's publication How  are the Toxics
Release Inventory Data Used? at www.epa.gov/tri/guide_docs/2003_datausepaper.pdf.

-------
What are the limitations of the TRI  data?

Users of TRI data should be aware that TRI data reflect dis-
posal or other releases and other waste management activities for
chemicals, not whether (or to what degree) the public has been
exposed to them. Both the toxicity of a chemical and exposure
should be taken into  account when using the data.

 TRI chemicals vary  widely in toxicity, or their  potential to
  produce toxic effects. Some high-volume releases of less toxic
  chemicals may appear to be more serious than lower-volume re-
  leases of highly toxic chemicals, when just the  opposite may be
  true.
 The potential for exposure may be greater the longer the chemical
  remains unchanged in the environment. Sunlight, heat, or microorgan-
  isms may or may not decompose the chemical. Smaller releases of a per-
  sistent, highly toxic chemical may create more serious problems than larger
  releases of chemicals that are rapidly converted to less toxic forms.

For more detailed information on this subject refer to theToxics Release Inventory (TRI) and
Factors to Consider When  Using TRI Data document at www.epa.gov/tri/tridata.


What should  I know about the different types of disposal or

other releases?

The TRI Program collects data on  a number of different types of disposal or other releases, as well as on cer-
tain waste management and recycling practices. Disposal or other releases of chemicals into the environment
occur through a range of practices  that may ultimately affect the potential for human exposure to the toxic
chemicals. Facility releases may include discharges to air, water, and land. Facilities limit contamination and
human exposure by disposing of or otherwise releasing waste in certain ways. For example:

 Disposal of harmful  materials to Class  I  Underground Injection wells located  in isolated formations
  beneath the lowermost underground sources of drinking water, which limits potential for contamination;
  and
 Disposal to landfills  that  are designed  with liners, covers, leak-detection systems, and groundwater
  monitoring systems also limit the potential for human exposure to the contents of the landfill.

Most disposal or other release practices are subject to a variety of regulatory requirements designed to limit
environmental harm. Please refer to the Toxics Release Inventory (TRI) and Factors to Consider When Using TRI
Data (www.epa.gov/tri/tridata) for more information on the  differences of these data elements.


What should  I know about persistent bioaccumulative  toxic

(PBT) chemicals?

Starting in 2000, EPA established more  stringent reporting thresholds for persistent bioaccumulative toxic
(PBT) chemicals originally on, or added to, the TRI chemical list. PBT chemicals are of particular concern
not only because they are toxic but also because they remain in the environment for long periods of time, are
not readily destroyed, and build up or accumulate in body tissue. The TRI PBT chemicals include dioxin and
dioxin-like compounds, lead and lead compounds, mercury and mercury compounds, polycyclic aromatic
compounds (PACs), polychlorinated biphenyls (PCBs), and certain pesticides, among other chemicals.

For more detailed information about the Agency's multimedia  strategy for priority PBT chemicals, visit

                         What do TRI data show for
                         reporting year (RY) 2003?
                        For RY 2003, 23,811 facilities, including federal facilities,
                       reported to EPA's TRI Program. They reported 4.44 billion
                      pounds  of on-site and  off-site disposal or other releases of
                    the almost 650 toxic chemicals, as shown in Table 1. Over 88
                  percent of the total was disposed of or otherwise released on-site;
               almost 12 percent was sent  off-site for disposal or other releases, as
          shown in Figure 2.
Persistant bioaccumulative toxic (PBT) chemicals accounted for 464.8 million pounds
or 10% of reported on- and off-site disposal or other releases in RY 2003. Of that total,
lead and lead compounds accounted for 93% or 432.0 million pounds. Total disposal
or other releases for mercury and mercury compounds were 7.4 million pounds and,
for dioxin and dioxin-like compounds, they were 269,050 grams. PCBs accounted
for 5% or 22 million pounds of the  total  disposal or other releases of PBT chemicals
in 2003.
All federal facilities, whether operated by  federal agencies or contractors (e.g. military
bases), are directed to report to EPA'sTRI Program.  For RY 2003, a total of 295 fed-
eral facilities submitted 977  forms and reported 78.1 million pounds of total on-site
and off-site disposal or other releases.

How did the TRI  data change over time?
From RY 2002 to RY 2003, total disposal or other releases on- and off-site decreased
by 305.9 million pounds  or 6%. On-site disposal or other releases decreased by 7%,
while off-site disposal  or other releases increased by less than  1%. Total production-
related waste managed decreased by 1.5%  over the same period. While the total num-
ber of facilities reporting decreased by 4% (888 facilities) from 2002, there was also a
3% decrease in the average  quantity disposed or otherwise released on- and off-site
per facility.
The metal mining and primary metals sectors accounted for 29% of total disposal or
other releases in 2003. If combined reporting by these two sectors is excluded, total
disposal or other releases and total production-related waste managed decreased by less
than 1% nationally.
Disposal or other releases of PBT chemicals increased by 11% in 2003. Disposal or
other releases for lead and lead compounds increased 7% from 2002 to 2003. Without
metal mining, disposal  or other releases of lead and lead compounds decreased by 3%.
Total  disposal or other releases of mercury and mercury compounds increased
by 41% (13% after accounting for a facility  data error) from 2002 to 2003,
although air emissions of mercury and its compounds decreased by 1%. Total
disposal or  other releases  of dioxin  and dioxin-like compounds increased
by 129,433 grams from 2002 to  2003. Excluding one facility that  reported
an increase  of 134,269 grams, total disposal or other releases of dioxin and
dioxin-like compounds decreased by 4%. Disposal or other releases of PCBs
increased by 20.4 million pounds from 2002 to 2003.
Federal facilities showed an overall decrease in disposal or other releases of 7.4 million
pounds or 9% from 2002 to 2003. Total production-related waste managed  at federal
facilities decreased by 5.5 million pounds  or 3%.
Starting in 1998, additional industries were required to report, including electric utili-
ties, metal and coal mines, commercial hazardous waste treatment facilities and solvent
recovery facilities, chemical wholesale distributors, and petroleum terminals and bulk
stations. From 1998 to 2003, all TRI  facilities, including those from the sectors added
in 1998, have reported a 42% reduction in disposal or other releases, as shown in
Figure 3.
Manufacturing facilities have been required to report to EPA's TRI Program
since  1987. From 1988 to 2003,  manufacturing facilities decreased their on-
and off-site disposal or other releases by 59%, as shown in Figure 4.

 includes:

   a summary of key findings which provides a detailed look at the 2003 data;
   a TRI Data in Context section which provides trend information and additional ways to view and interpret
   TRI data; and
   additional tables and charts which provide a look at the top chemicals, industries, and facilities for 2003.
