Assignment and Application of the ``Unique Identifier' Under TSCA Section 14 (Draft)
Feb. 9, 2018
Recent amendments to TSCA) require EPA to develop a system 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 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 previously requested comment on approaches for assigning and applying unique identifiers, and has developed an additional approach on which it now requests comment. EPA will accept written comments and materials submitted to the docket on or before 12 March 2018.
