Hexachlorobutadiene HCBD;
Regulation of Persistent, Bioaccumulative, and Toxic Chemicals Under TSCA Section 6h Environmental Protection Agency EPA.
ACTION: Final rule.
AGENCY:

Therefore, for the reasons stated in the preamble, 40 CFR part 751 is amended as follows:

751.403

BILLING CODE 656050P

Jkt 253001

The Environmental Protection Agency EPA is finalizing a rule under the Toxic Substances Control Act TSCA to address its obligations under TSCA for hexachlorobutadiene HCBD
CASRN 87683, which EPA has determined meets the requirements for expedited action under TSCA. This final rule prohibits all manufacturing including import, processing, and distribution in commerce of HCBD and HCBD-containing products or articles, recognizing that there is unintentional production of HCBD as a byproduct during the production of chlorinated solvents, and that results in distribution in commerce of a very limited subset of that byproduct for burning as a waste fuel. These requirements will impact the amount of HCBD that will be manufactured, processed, distributed in commerce, used or disposed, thus reducing the exposures to humans and the environment from those activities prohibited under this final rule.
DATES: This final rule is effective February 5, 2021. For purposes of judicial review and 40 CFR 23.5, this rule shall be promulgated at 1 p.m.
eastern standard time on January 21, 2021.
