Toxic Release Inventory

If your business deals with or creates toxic chemicals, it needs to comply with the laws and regulations set by the U.S. Environmental Protection Agency (EPA).

The Toxics Release Inventory (TRI) is a publicly available EPA database that contains information on toxic chemical releases and other waste management activities reported annually by certain covered industry groups and federal facilities. This inventory was established under the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA) and expanded by the Pollution Prevention Act of 1990.

The resources below can help you gain a more thorough understanding of the requirements concerning toxic chemical releases and your business' role in compliance.

Who Must Comply

  • Release Reporting Requirements

How to Comply

EPCRA Section 313 requires facilities to submit reports to both the EPA and their state. Reports must be submitted by July 1 of each year. Separate copies of the report should be sent to the EPA and the state. Facilities that reside in states that participate in the TRI State Data Exchange and file with the EPA electronically will automatically have their submissions sent to the state. The reporting software will inform facilities if their state is participating in this program.
