TRI Threshold Screening Tool

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 Reporting Requirements

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

• The facility is included in a TRI-covered North American Industry Classification System (NAICS) code; and
• The facility has 10 or more full-time employee equivalents (i.e., a total of 20,000 hours or greater; see 40 CFR 372.3); and
• The facility manufactures (defined to include importing), processes or otherwise uses any EPCRA Section 313 chemical in quantities greater than the established threshold during a calendar year.

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).
