Toxics Release Inventory (TRI)

The Toxics Release Inventory (TRI) is Section 313 of the federal Emergency Planning and Community Right-to-Know Act. This law requires covered 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. Covered facilities engage in manufacturing, coal-fired electric power generation, commercial hazardous waste disposal, solvent recovery or serve as bulk petroleum terminals. Facilities in these categories must have the equivalent of at least 10 full time employees and process, manufacture or use at least one listed toxic chemicals. The reports are compiled into a database and the information is available to the public. Additionally DEQ prepares a TRI Summary Report that is available on-line or by contacting Jami Murphy, 405-702-1011, Jami Murphy.
