Recent amendments to the Toxic Substances Control Act (TSCA) require EPA to assign a “unique identifier” whenever it approves a Confidential Business Information (CBI) claim for the specific chemical identity of a chemical substance, to apply this unique identifier to other information or submissions concerning the same substance, and to ensure that any nonconfidential information received by the Agency identifies the chemical substance using the unique identifier while the specific chemical identity of the chemical substance is protected from disclosure.
EPA is holding a public meeting and requesting comment on approaches for assigning and applying unique identifiers for chemical substances reported in a Confidential Business Information claim. The meeting will be held on May 24, 2017, from 1:00 p.m. to 4:00 p.m. (EDT) in Washington, D.C., and is also available by remote access. Registration is available online and requested by May 22, 2017. Thereafter, written comments and materials will be accepted if submitted to the docket on or before July 7, 2017. Further information is available at the original Federal Register notice, 82 Fed. Reg. 21386.
