TSCA’s 20 High-Priority Substances - Requirements for Manufacturers/importers to Self-Identify
Mar 24, 2020
On January 27, 2020, the U.S. EPA published a Federal Register notice identifying the preliminary list of manufacturers (including importers) of the 20 high-priority substances for which the fees will be charged. During the comment period, currently scheduled to end March 27, 2020, all manufacturers (and importers) of any of the 20 high-priority substances are required to self-identify, whether or not they were included on EPA’s initial list. This is also an opportunity for manufacturers (and importers) to certify they were improperly included on the list. The EPA announced publicly that they are likely going to extend the comment period through May 27, 2020, although this has not yet become finalized.
