TRI Chemicals
The current TRI toxic chemical list contains 582 individually listed
chemicals and 30 chemical categories (including 3 delimited categories
containing 58 chemicals). If the members of the three delimited categories
are counted as separate chemicals then the total number of chemicals and
chemical categories is 667 (i.e., 582 + 27 + 58). This page contains links
to information on TRI chemical lists, tri
pbt chemicals, list changes, toxicity,
regulatory program information, fact sheets, and
chemical specific guidance
documents.
Note: Three chemicals on the current list (methyl mercaptan,
hydrogen sulfide, and 2,2-dibromo-3-nitrilopropionamide) are under administrative
stays and are not currently reportable.

TRI Chemical List
Changes (1987- 2001)
- TRI Chemical List Changes (PDF, 26KB)
EPA has made chemical list changes through the chemical petitions process
and EPA-initiated review, therefore, the TRI list of reportable toxic
chemicals can vary from year to year. The chemicals reportable in a
given year are listed by the date of the reporting year. For information
about the toxic effects of some of the TRI chemicals, see Toxicity Information,
and for lists of regulations that cover some TRI chemicals, see Regulatory
Program information.
Regulatory Program Information
- TITLE III List
of Lists (PDF, 586KB)
This is a consolidated list of chemicals subject to reporting requirements
under Title III of the Superfund Amendments and Reauthorization Act
of 1986 (SARA) with references to their reporting status under Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA or Superfund),
The Resource Conservation and Recovery Act (RCRA), and Sections 302
and 313 of The Emergency Planning & Community Right-To-Know Act (EPCRA).
- Regulatory Matrix of TRI Chemicals in other
Federal Programs (PDF, 183KB)
A matrix has been developed for each TRI chemical indicating whether
it is regulated under other selected environmental laws.
Toxicity Information
- Hazard Information on Toxic Chemicals Added
to EPCRA Section 313 Under Chemical Expansion.
This page provides summary hazard information on the 286 chemicals that
were added to the Toxics Release Inventory in 1994. EPA has developed
information summaries on 40
selected TRI chemicals to describe how you might be exposed to these
chemicals, how exposure to them might affect you and the environment,
what happens to them in the environment, who regulates them, and whom
to contact for additional information.
- TRI
Chemical Fact Sheets
Chemical fact sheets for many of the TRI chemicals are available from
the collection of New Jersey’s Right to Know Hazardous Substance
Fact Sheets.
- TRI Chemicals Classified as OSHA Carcinogens
This is a list of TRI chemicals that are classified as carcinogens under
the requirements of the Occupation Safety and Health Administration
(OSHA) and, the basis of the classifications. OSHA carcinogens have
a 0.1% de minimis concentration limit instead of 1%. Amounts of TRI
chemicals present below the de minimis concentration limit in mixtures
do not have to be included in threshold determinations or release and
other waste management calculations.
- ATSDR TOXFAQS
These are a series of summaries developed by the Agency for Toxic Substances
and Disease Registry (ATSDR) that contain frequently asked questions
about the health effect for 60 hazardous substances. About 50 of these
chemicals are also TRI chemicals.
