Revocation of Guidelines for Making Corrections to the TSCA Inventory

EPA is phasing out its July 1980 process for requesting corrections to the Toxic Substances Control Act (TSCA) Inventory. Starting on April 26, 2022, companies may need to submit a premanufacture notice (PMN) or exemption notice in order to request a change to the specific chemical identity of a substance listed on the Inventory.

EPA will be discontinuing processing Inventory corrections, withdrawing its 1980 Inventory Correction guidelines, and phasing out the accompanying procedures by which companies that reported an incorrectly identified chemical on an original Inventory reporting form may request a correction of that Inventory listing.

The phase-out period for correction requests ends on April 26, 2022. During the phase-out period EPA will continue to accept correction requests that are complete and meet the correction guidelines published in 1980. Correction requests that are incomplete or that are ineligible according to the guidelines will be rejected by EPA.

If after April 26, 2022, a company discovers for any reason a change in the specific chemical identity of a chemical substance reported on an original Inventory reporting form, a PMN or exemption notice may need to be filed if the chemical substance is not already listed on the TSCA Inventory.

This action does not impact EPA’s authority for initiating, at its discretion, corrections to the Inventory should the agency determine on its own that, for example, a chemical substance listed on the Inventory has been unintentionally misidentified. In this situation will EPA, at its discretion, request and accept documentation from a company to support an Inventory correction in lieu of requiring a PMN or exemption notice. This action also does not impact EPA’s regular maintenance of the Inventory that can include nomenclature updates and correcting minor errors to listings.

Read the federal register notice for this action.
