TRI Laws and Regulatory Activities

Laws and Executive Orders

  • 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 .

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 .

  • Addition of 1-Bromopropane (Proposed in April 2015): EPA published a proposed rule to add 1-bromopropane to the list of chemicals subject to TRI reporting. The National Toxicology Program classifies 1-brompropane as "reasonably anticipated to be a human carcinogen."
  • Addition of a Nonylphenol Category (Finalized in September 2014): EPA published a final rule to add a nonylphenol category to the list of chemicals subject to TRI reporting. Nonylphenol is highly toxic to aquatic organisms and has been found in ambient waters.
  • Addition of ortho-Nitrotoluene (Finalized in November 2013): EPA finalized a rule to add ortho-nitrotoluene to the list of chemicals subject to TRI reporting. The National Toxicology Program classifies o-Nitrotoluene as "reasonably anticipated to be a human carcinogen."
  • Potential TRI Sectors Expansion (Pre-proposal): EPA is considering whether to broaden the scope of industry sectors subject to TRI reporting to include the following: Steam Generation from Coal and/or Oil, Petroleum Bulk Storage, Iron Ore Mining, Phosphate Mining, Large Dry Cleaning Facilities and Solid Waste Combustors and Incinerators.

Past Rulemakings

TRI rulemakings are grouped below based on whether they are related to chemicals, industry sectors or other changes in TRI reporting requirements. Links to rules published before 2009 go directly to the relevant text in the Federal Register.

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.
