Toxics Release Inventory (TRI) Program
You will need Adobe Reader to view the Portable Document Format (PDF) files.
The current TRI toxic chemical list contains 593 individually-listed chemicals and 30 chemical categories (including three categories containing 62 specifically-listed chemicals). If the members of the three delimited categories are counted as separate chemicals, the TRI Program covers 682 chemicals and chemical categories (i.e., 593 + 27 + 62).
Note: methyl mercaptan and 2,2-dibromo-3-nitrilopropionamide are under administrative stays and are not currently reportable.
Recent Changes to the TRI Chemical List
- EPA Reinstates TRI Reporting Requirements for Hydrogen Sulfide
- EPA Finalizes Rule to Add 16 Chemicals to TRI Chemical List
EPA reinstated the TRI reporting requirements for hydrogen sulfide as part of Administrator Lisa P. Jackson's ongoing efforts to provide the public with helpful information on chemicals they may encounter in their daily lives. This action will be effective for the 2012 TRI reporting year, with the first 2012 TRI reports due from facilities by July 1, 2013.
EPA finalized a rule to add 16 chemicals reasonably anticipated to be human carcinogens to the TRI list of reportable chemicals. This action is part of the EPA's ongoing efforts to examine the scope of TRI chemical coverage and provide communities with more complete information on toxic chemical releases. It is the largest chemical expansion of the program in over a decade and is effective for the 2011 TRI reporting year.
TRI Chemical List Changes (1987 - 2012)
EPA makes changes to the TRI chemical list through EPA-initiated review and through the chemical petitions process. As a result, the TRI list of reportable toxic chemicals can vary from year to year. TRI Chemical List Changes (PDF) ( 12pp, 133KB) lists all of the additions and deletions to the TRI chemical list and indicates the first or last reporting year for those chemicals.
Persistent Bioaccumulative Toxic (PBT) Chemicals
PBT chemicals have lower reporting thresholds than other TRI chemicals. PBTs are of particular concern not only because they are toxic, but because they remain in the environment for long periods of time, are not readily destroyed and build up or accumulate in body tissue.

TRI Chemicals and Other EPA Regulatory Programs
- TITLE III List of Lists (PDF) (98 pp, 4.69MB)
- Regulatory Matrix of TRI Chemicals in other Federal Programs (PDF) (9 pp., 179KB)
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 the 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).
A matrix has been developed for each TRI chemical indicating whether it is regulated under other selected environmental laws.

- TRI Chemicals Classified as OSHA Carcinogens
TRI's searchable database system contains hazard information for TRI chemicals. Among other features, users can search for toxicity information on TRI chemicals from multiple information sources and identify TRI chemicals associated with a critical adverse human health effect of interest.
ToxFAQs is a series of printable fact sheets that answer the most frequently asked questions about exposure to nearly 200 toxic chemicals and the effects of exposure on human health. Many of these chemicals are also TRI chemicals.
The New Jersey's Department of Health's library of fact sheets includes information on over 1600 hazardous substances, over half of which have been translated into Spanish. Many of these fact sheets cover TRI chemicals.
Summary hazard information on the 286 chemicals that were added to the Toxics Release Inventory in 1994.
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.
