Laws and Executive Orders

The Toxics Release Inventory (TRI) was established in 1986 by the Emergency Planning and Community Right-to-Know Act (EPCRA). In 1990, Congress passed the Pollution Prevention Act (PPA), which required that facilities report additional data on waste management and source reduction activities under TRI. The TRI-specific sections of these two laws are Section 313 of EPCRA and Section 6607 of PPA.

The Code of Federal Regulations (CFR) is the codification of rules published in the Federal Register by the executive departments and agencies of the Federal Government. It is divided into 50 titles that represent broad areas subject to Federal regulation, with environmental regulations contained mainly in title 40. TRI regulations can be found at 40 CFR Part 372 .

An Executive Order (EO) in 1993 required federal facilities to comply with Section 313 of EPCRA regardless of their primary North American Industry Classification System (NAICS) code. Two additional EOs reinforced this requirement.

Rulemakings

The TRI Program is modified over time through rulemakings. You can browse TRI rulemakings or learn more about the rulemaking process at EPA.

Current Regulatory Development Activities

The TRI Program is involved in several regulatory development activities:

  • Updating the TRI NAICS Codes - EPA has published proposed and direct final rules for updating the TRI NAICS Codes using the revised OMB 2012 NAICS. The 2012 TRI NAICS codes will be effective for Reporting Year 2013, for reports due to the Agency on or before July 1, 2014. If no adverse comments are received, the proposal is withdrawn and the direct final rule will go into effect 90 days from the date of publication. Comments on the proposed rule will be accepted until August 18, 2013.
  • Addition of a Nonylphenol Category - EPA has published a proposed rule to add a nonylphenol category to the to the TRI list of reportable chemicals. Nonylphenol is highly toxic to aquatic organisms and has been found in ambient waters. Comments on the proposed rule will be accepted until August 19, 2013.
  • Addition of ortho-Nitrotoluene - EPA has finalized a rule to add ortho-nitrotoluene to the list of chemicals subject to the list of TRI reportable chemicals. o-Nitrotoluene has been classified as "reasonably anticipated to be a human carcinogen" by the National Toxicology Program (NTP).
  • Potential TRI Sectors Expansion - EPA is considering whether to broaden the scope of industry sectors covered by EPCRA § 313 (the Toxics Release Inventory Program) to include the following industry sectors: Steam Generation from Coal and/or Oil, Petroleum Bulk Storage, Iron Ore Mining, Phosphate Mining, Large Dry Cleaning and Solid Waste Combustors and Incinerators.
  • Requiring Electronic Reporting Under Section 313 of EPCRA - EPA has finalized a rule to require the electronic reporting of non-confidential TRI data using the Web-based TRI-MEweb reporting application.
  • Modification of Toxics Release Inventory Reporting Requirements Primarily Associated with Metal MiningAfter careful consideration of the full regulatory agenda, current priorities, and resources, EPA has withdrawn from Office of Management and Budget review a draft notice of proposed rulemaking regarding reporting requirements for the metal mining industry under the TRI Program. Individual metal mining facilities continue to remain responsible for complying with their statutory TRI reporting obligations under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA).    
  • Articles Exemption Clarification Proposed Rule - In August of 2009, EPA proposed a rule to clarify the TRI articles exemption. EPA has since withdrawn the proposal and is considering publishing a supplemental proposed rule in order to respond to comments received.

Information Collection Requests (ICRs)

An ICR is a set of documents that describe reporting, record keeping, survey or other information collection requirements imposed on the public by EPA. The ICR provides an overview of the collection and estimates the cost and time for the public to respond. The public may view an ICR and submit comments on it at any time. TRI ICRs are resubmitted for approval by the Office of Management and Budget (OMB) every 2-3 years.
