Toxics Release Inventory (TRI) Program

Electronic Reporting of Toxics Release Inventory Data - Final Rule

EPA has published a final rule requiring facilities to report all non-trade secret Toxics Release Inventory (TRI) data to EPA using the TRI-MEweb online reporting application.

This rule also requires facilities to electronically submit any revisions or withdrawals of previously-submitted TRI reporting forms. Facilities may revise or withdraw TRI forms going back to reporting year (RY) 1991, but not for years prior to this.

Why has EPA published this final rule?

Widespread use of TRI-MEweb improves the quality and accuracy of TRI data and allows EPA to get the data to the public faster. The majority of TRI facilities already submit their TRI forms electronically using TRI-MEweb.

How many facilities are expected to be affected by this rule and when does it take effect?

This rule applies to all facilities required to report to the TRI Program. This rule is effective January 21, 2014. Once the rule becomes effective, facilities submitting non-trade-secret TRI reporting forms for the 2013 TRI reporting year (forms due on July 1, 2014) or prior reporting years must report electronically.

How will the submission of trade secret information be impacted?

The few facilities that submit trade secret TRI information will continue to submit their trade secret reporting forms and substantiation forms in hard copy, as well as any revisions or withdrawals of previously-submitted trade secret information.
