Toxics Release Inventory
EPCRA Section 313: Toxics Release Inventory (TRI)
The Toxics Release Inventory (TRI) is Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA). This law requires regulated facilities and federal installations to submit reports annually to both DEQ and the EPA describing chemical releases and waste management activities for over 600 toxic chemicals.
If a facility meets all three of the following criteria, they must report annually to the TRI Program by July 1:
- If a facility engages in manufacturing, electric power generation, commercial hazardous waste disposal, solvent recovery, or serves as bulk petroleum terminals. For a complete list of TRI-covered NAICS codes, click here.
- The facility has the equivalent of at least 10 full-time employees
- Processes, manufactures, or uses at least one TRI-listed chemical at or above the reporting threshold.
Beginning in the 2014 reporting year, EPA no longer accepts paper submissions. If your facility must report to the TRI Program and you need guidance on electronic reporting, click here for additional assistance.
