Laws and Executive Orders

  • Emergency Planning and Community Right-to-Know Act (EPCRA): In 1986, Congress passed EPCRA, Section 313 of which created the Toxics Release Inventory (TRI).
    • Get a short guide to EPCRA or a one-page factsheet
    • Read the full text of EPCRA
    • Learn more about EPCRA
  • Pollution Prevention Act (PPA): In 1990, Congress passed the PPA, Section 6607 of which required that facilities report additional data on waste management and source reduction activities to TRI.

    • Read the full text of the PPA
    • Learn more about TRI's pollution prevention data
  • ​National Defense Authorization Act (NDAA) for Fiscal Year 2020: In 2019, Congress passed the NDAA for Fiscal Year 2020, Section 7321 of which added certain per- and polyfluoroalkyl substances (PFAS) to the list of chemicals covered by TRI and provided a framework for listing additional PFAS.
    • Read a summary of Section 7321 of the NDAA for Fiscal Year 2020
  • Code of Federal Regulations (CFR): The 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.
  • Executive Orders: An executive order is signed by the President and has the force of law. In 1993, President Clinton signed an EO requiring federal facilities to comply with Section 313 of EPCRA regardless of their primary North American Industry Classification System (NAICS) code. Subsequent EOs have not changed this requirement.
    • Federal Compliance With Right-To-Know Laws and Pollution Prevention Requirements (PDF): EO 12856: August 3, 1993(6 pp, 12 K)

Current Petitions

Any person may petition EPA to add a chemical to or remove a chemical from the TRI list. Additionally, under the Administrative Procedure Act (APA), federal agencies must give interested persons the right to petition for the issuance, amendment, or repeal of a rule, which allows interested persons to solicit changes to the reporting requirements for TRI. 5 U.S.C. § 553(e).

Current petitions being considered by the TRI Program:

  • Petition from the Toxics Use Reduction Institute (TURI) to Add 25 Chemicals to the TRI List

Information Collection Requests

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.

Current TRI ICR Renewal (Submitted on 7/31/20)

In compliance with the Paperwork Reduction Act (PRA), EPA has submitted an ICR to OMB for review and approval. This ICR consolidates two ICRs (2070-0212 and 2025-009) and renews TRI reporting forms for a three-year period.

Prior TRI ICR Renewals

TRI ICRs are resubmitted for approval by the Office of Management and Budget (OMB) every 2-3 years.
