The US EPA Announces Latest Version of TSCA Inventory Includes Unique Identifier Information
On September 19, 2019, the U.S. Environmental Protection Agency (EPA) announced that it posted the first public Toxic Substances Control Act (TSCA) Inventory to include unique identifier (UID) information. The purpose of UIDs is to enable the public to connect specific chemical identities previously listed on the confidential portion of the TSCA Inventory with other relevant information in the Agency’s holdings.
EPA recently added two new fields to the public Toxic Substances Control Act (TSCA) Inventory: UI (for the unique identifier or UID) and EX (indicating the expiration date of the confidential business information (CBI) claim). A UID is a numerical identifier assigned to a chemical substance when EPA approves a CBI claim for specific chemical identity. When EPA approves such a claim, it assigns a UID to that chemical identity; applies the UID to other information or submissions concerning the same substance; and ensures that any non-confidential information received by EPA identifies the chemical substance using the UID while the specific chemical identity of the chemical substance is protected from disclosure. Then, if ever a CBI claim is denied or withdrawn, the unique identifier will remain associated to the now non-CBI entry in the TSCA inventory connecting the specific chemical identity to the information on the chemical substance.
