  • National Defense Authorization Act (NDAA) for Fiscal Year 2020: In 2019, the NDAA for Fiscal Year 2020 was enacted, 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.  
  • 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.

Recent/Ongoing Rulemakings

The TRI Program is modified over time through rulemakings. The most recent are listed below. Note that all rules published in the Federal Register by the TRI Program are also found in the Code of Federal Regulations. TRI regulations can be found at 40 CFR Part 372.

  • Implementing Statutory Addition of Certain Per- and Polyfluoroalkyl Substances (Finalized in June 2020): Pursuant to the National Defense Authorization Act for Fiscal Year 2020 (NDAA), EPA published a final rule that added 172 per- and polyfluoroalkyl substances (PFAS) to the list of toxic chemicals subject to TRI reporting.  
  • Corrections to TRI Reporting Requirements (Finalized in May 2020): EPA has finalized a rule to correct certain existing TRI regulatory language. These corrections will provide greater clarity for facilities and other stakeholders.
  • Advance Notice of Proposed Rulemaking (ANPRM): Adding Certain PFAS to the TRI List (November 2019): EPA is announcing the opening of a 60-day public comment period to inform a potential rulemaking to add certain per- and polyfluoroalkyl substances (PFAS) to the list of chemicals companies are required to report on for the TRI.
  • Addition of NPEs Category (Finalized in June 2018): EPA  finalized a rule that adds a category of 13 specific nonylphenol ethoxylates (NPEs) to the list of chemicals subject to TRI reporting. NPEs are nonionic surfactants used in adhesives, wetting agents, emulsifiers, stabilizers, dispersants, defoamers, cleaners, paints, and coatings.

Petition(s)

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:

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.

Current TRI ICR Renewal (Proposed on 3/12/20)

In compliance with the Paperwork Reduction Act (PRA), EPA published in the Federal Register its plan to submit an ICR to OMB that would consolidate two ICRs (2070-0212 and 2025-009) and renew 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.
