Toxics Release Inventory (TRI) Program

Addition of Facilities in Certain Industry Sectors

On this page:

Rule Summary

In May 1997, EPA added seven industry groups to the list of facilities subject to the reporting requirements of Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA) and Section 6607 of the Pollution Prevention Act of 1990 (PPA):

  • Metal mining
  • Coal mining
  • Electric utilities
  • Commercial hazardous waste treatment
  • Chemicals and allied products-wholesale
  • Petroleum bulk terminals and plants-wholesale
  • Solvent recovery services

The addition of these sectors allowed the Toxics Release Inventory Program to more completely account for the use, management, and disposition of toxic chemicals in the United States. TRI provides the public, government, and the regulated community with information to improve decision making, measurement of pollution, and the understanding of the environmental and health consequences of toxic chemical releases and other waste management activities.

Rule History

EPA first announced its intention to consider the expansion of the Toxics Release Inventory Program to include facilities in additional industry groups at a public meeting held on May 29, 1992. 

Prior to the proposed rule, EPA designed and executed a screening process intended to identify those industry groups potentially most relevant to the purposes of EPCRA Section 313.
