Reporting for TRI Facilities

TRI Reporting Deadline
 

Each year, certain industrial facilities submit Toxics Release Inventory (TRI) data to EPA. The data are due by July 1 and cover waste management activities that occurred during the previous calendar year. EPA makes these data publicly available.

Is Your Facility Required to Report to the TRI Program?

Reporting Help
  • Reporting hotlines and TRI Coordinators can help answer regulatory and reporting questions.
  • The Introduction to TRI for Industry slide presentation can answer basic TRI questions.
  • A facility is required to report if it meets chemical activity thresholds and
    • is either in a covered industry sector and exceeds the employee threshold, or
    • is specifically required to report based a determination by the Administrator under EPCRA 313(b)(2).

  • The TRI Threshold Screening Tool can help you determine if your facility is required to report.

How is TRI Reporting Related to Tier II Reporting?

TRI reporting is required under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA). Tier II reporting is required under Section 312 of EPCRA. TRI reporting requirements are separate and distinct from Tier II reporting requirements. Submitting TRI reporting forms does not fulfill a facility's Tier II reporting requirements, or vice versa. For more about what EPCRA requires, see the EPCRA factsheet or quick guide.

Overview of the TRI Reporting Process

The image below summarizes the TRI reporting process. For more detailed information about each step, refer to the TRI Reporting Forms and Instructions.

TRI Reporting Steps

Reporting Changes for RY 2021

  • All natural gas processing facilities that receive and refine natural gas are now subject to TRI reporting requirements, per a final rule published in November 2021.
  • The National Defense Authorization Act for Fiscal Year 2020 became effective on January 1, 2020. For reporting year 2021, four additional PFAS have been added per the requirements of the NDAA. These are: 
    • silver(I) perfluorooctanoate (335-93-3),
    • perfluorooctyl iodide (507-63-1), 
    • potassium perfluorooctanoate (2395-00-8), and
    • 2-Propenoic acid, 2-methyl-, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-heneicosafluorododecyl ester, polymer with 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl 2-methyl-2-propenoate, methyl 2-methyl-2-propenoate, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,14-pentacosafluorotetradecyl 2-methyl-2-propenoate and 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl 2-methyl-2-propenoate (65104-45-2).
  • Twenty-nine contract sterilization facilities must estimate their quantities of ethylene oxide manufactured, processed, and otherwise used (and for some facilities, ethylene glycol as well) to determine whether TRI reporting is required, following a determination by the EPA Administrator to extend TRI reporting requirements to these particular facilities under EPCRA section 313(b)(2).
  • EPA revised the source reduction activity codes to improve clarity and better reflect industrial activity. There are now 24 activity (S) codes corresponding to five categories.

TRI Training and Guidance Materials

GuideME

Information accessible via GuideME includes reporting instructions, the TRI chemical list, chemical- and industry-specific guidance, policy directives, training materials, questions and answers, and more.

Emissions Factors Guidance

EPA publishes emissions factors that apply to multiple chemicals and processes. Facilities that are subject to TRI reporting requirements may find these emission factors useful for estimating reportable quantities of TRI chemicals.
