Toxics Release (TRI) is a EPA database which contains information on listed toxic chemical releases and other waste
management activities to be reported annually by companies who meet minimum quantity thresholds. This TRI was established by the Emergency Planning and
Community Right-to-Know Act of 1986 (EPCRA) and expanded by the Pollution Prevention Act of 1990.
