Public Data Release

Questions, Answers and Facts

What is the Toxics Release Inventory (TRI)
Program?

Congress passed the Emergency Planning and
Community Right-to-Know Act (EPCRA) in 1986.
Section 313 of EPCRA, called the Toxics Release
Inventory (TRI), mandates that certain businesses
submit annual reports detailing the release and
management of toxic chemicals.

Based on the premise that people have a right to know
about toxic chemicals in their community, these
emission reports are compiled into a computerized
database and then made available to the public. This
database, easily available over the Internet, can be
used to provide information on emissions from a
particular facility, in a particular community, or of a
particular chemical. In many cases this information
has stimulated reductions in emissions, both through
focusing facility managers' attention on waste and its
reduction, and through increased involvement by the
public. Since the program's inception, reported
releases, as adjusted for changes in the reporting
requirements, have decreased by about 45%.

New Information-the 1998 Data

The reporting requirements-originally restricted to the
manufacturing sector— were recently expanded to
seven new industry sectors. The 1998 data includes,
for the first time, toxic chemical release information
from the metal and coal mining industry, electricity
generating facilities, commercial hazardous waste
treatment facilities, solvent recovery services,
petroleum bulk terminals, and wholesale chemical
distributors. This is exciting and important new
information from nearly 2000 newly reporting
facilities, documenting 4.93 billion pounds of toxic
chemical releases.

Some Facts About the 7 New Industry Sectors

Metal Mining

In terms of total pounds of chemicals released on-
and off-site, the metal mining industry is the most
important new industry, with national releases totaling
3.51 billion pounds. Many mines extract, move, store,
process, and dispose of large amounts of waste rock
and ore-materials which often contains low
concentrations of naturally occurring metals. The
vast majority of this material is placed in surface
impoundments or on the land, and the metals are
reported as on-site releases to land. This previously
buried material is exposed to potential leaching by
rain, snow, and acid mine drainage, and must be
carefully managed and monitored to prevent any
surface water or groundwater contamination. There
are also air releases from ore processing and metal
refining operations.

Electricity Generating Facilities
In terms of total pounds of chemicals released on-
and off-site, the electricity generating industry is the
second most important new industry. In 1998 the
sector released 1.12 billion pounds of chemicals
nationwide, a fairly large number when you consider
that all of the original industries combined released
2.4 billion pounds of chemicals in 1998. From coal-
fired plants, typical releases are of metals contained
in the coal ash generated during coal combustion.
Large quantities of this ash may be disposed of in on-
or off-site landfills, or returned to coal mines for
disposal. Other releases reported include
hydrochloric acid, hydrogen fluoride and
formaldehyde; these chemicals are formed during
combustion. In Region 8, air releases of acids and
the disposal of coal ash to on- and off-site landfills
made up the majority of this sector's releases.

Coal Mining

Nationally, this industry reported 13.3 million pounds of
releases; of that, 11.5 million pounds were released to
land in the form of coal ash. Coal ash contains low
concentrations of metals and metal compounds.

Commercial Hazardous Waste Treatment
These are the facilities that treat, store, and dispose
hazardous waste (they are known by the acronym
TSD). The reporting requirements apply only to those
TSD facilities regulated by subtitle C of RCRA, which
is the most stringent level of regulation. For analytic
purposes, this industry's releases were combined with
those from solvent recyclers, and nationally, releases
totaled 281.8 million pounds. As this industry's
purpose of business is to treat wastes and dispose of
them into on-site landfills, that is where almost all of
the reported releases went. Most facilities also
reported air emissions.

Solvent Recovery Services
This industry collects, recycles, and redistributes
solvents used in many industrial applications. As many
of the facilities are co-located with Commercial
Hazardous Waste Treatment facilities, their releases
were aggregated and analyzed in conjunction with
each other.

Petroleum Bulk Terminals
These establishments are primarily engaged in the
wholesale distribution of petroleum products. As an
industry, they reported 4.7 million pounds of releases in
1998, and most of that, 4.3 million pounds, went to the
air. Chemicals releases most frequently reported were
for typical constituents of gasoline: benzene, toluene,
ethyl benzene, xylene, and in California, methyl tert-
butyl ether.

Wholesale Chemical Distributors
In the course of distributing chemicals, many
wholesalers repackage and sometimes reformulate
their products. Nationally, this industry reported
releases of 1.6 million pounds, with the vast majority of
releases going to the air.

A Note on TRI and Releases:

When compiling information for sector analyses, EPA
aggregates all the on-site releases (air, water, and
land disposal), and the amounts transferred off-site
for disposal to form a number called 'total release.'
When comparing data from year to year, the data is
often normalized to account for changes in the list of
reportable chemicals.

It is important to note that release should not be
directly equated with risk. The TRI is meant to
provide a starting point; emission reports from a
facility should be used in conjunction with other
information like chemical toxicity, site-specific
conditions, and exposure potential.
