Toxics Release Inventory (TRI) Program

TRI Threshold Screening Tool

Note: The tool provides reporting requirements for reporting year 2017.

The Toxics Release Inventory (TRI) Threshold Screening Tool uses a step-by-step questionnaire to help facilities determine if they meet or exceed established facility, employee, and chemical thresholds and as such, may be required by Section 313 of the Emergency Planning and Community Right to Know Act (EPCRA) to report to the TRI Program.

This tool is only intended to help facilities determine if they are required to submit annual TRI data; it does not help facilities fill out TRI reporting forms. We suggest printing out the threshold screening report at the end of the tool's third section for your reference.

  • TRI/NEW EPA has recently upgraded the Threshold Screening Tool to help you determine if your facility is required to submit a TRI reporting form. We would appreciate your feedback on the tool and how we can improve it. Within the tool, please click the "Provide Feedback” button at the top center of the screen. Start using the TRI Threshold Screening Tool

TRI Reporting Requirements

Your facility is required to report to the TRI Program if it meets ALL of these three threshold criteria:

Please note that Executive Order 13423 extends these reporting requirements to federal facilities, regardless of their SIC or NAICS code.

Before Using the Tool

You'll need some information before you begin:

  • Your facility's NAICS code(s) and your facility type (e.g., federal, GOCO (Government-owned, contractor-operated), or neither).
  • The number of employees at your facility, the total hours worked per week and the total weeks worked during the reporting year.
  • The individual EPCRA Section 313 chemicals and/or members of chemical categories that were manufactured, processed, or otherwise used at your facility and the corresponding quantities for each type of chemical activity (i.e., manufactured, processed, or otherwise used).
