TRI Threshold Screening Tool

Threshold Screening Tool updated on January 17, 2012 with 16 new RY 2011 chemicals

The TRI Threshold Screening Tool uses a step-by-step questionnaire to assist facilities in determining whether they meet and/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 whether they are required to report TRI data. It doesn't help to fill out TRI reporting forms that facilities may be required to submit through the TRI-MEweb reporting application or on paper through regular mail. For this reason, we suggest that you print out the Threshold Screening Report at the end of the third threshold section for your reference.

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

  • The facility is included in a TRI-covered North American Industry Classification System (NAICS) code (see the TRI NAICS code webpage or Table I of the RY 2010 Reporting Forms and Instructions for a complete list); 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 in the course of a calendar year.

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

Before you begin using the Threshold Screening Tool, gather this information:

  • 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 EPCRA Section 313 chemicals and/or 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).

The TRI Threshold Determinations Tutorial (10 min ) is a narrated Powerpoint presentation that walks users through the TRI reporting thresholds. This information complements the Threshold Screening Tool.
