Description: The Environmental Protection Agency
(EPA or Agency) is taking interim final action on the Regulation of
Trichloroethylene (TCE) under the Toxic Substances Control
Act (TSCA) to revise certain compliance
deadlines finalized in 2024. Specifically, EPA is amending the prohibition
compliance date for the use of TCE as a processing aid in the manufacture of
nuclear fuel, with corresponding changes to the compliance dates for the
manufacturing, processing and distribution in commerce of TCE to support such
use, to a prohibition on 15 September 2028. EPA is also amending the
prohibition compliance date for the disposal of TCE to wastewater by processors
of TCE and processors and industrial and commercial users of TCE as a
processing aid, to begin on 18 December 2026. EPA is also amending the
compliance deadline for downstream notification, and the text required to be
present in Safety Data Sheets, to accurately reflect the new prohibition
compliance deadline for TCE used as a processing aid in the manufacture of
nuclear fuel. EPA is amending this compliance deadline to allow for 90 days
after the publication of the final rule for manufacturers, processors, and
distributors in commerce of TCE to make such a change. These revisions are
necessary to address new information presented to EPA about inadvertent
oversights in the original rulemaking and serious concerns that the facilities
at issue will be unable to comply with the relevant requirements by the
existing deadlines. EPA is requesting comments on all aspects of this interim
final rule and will consider all comments received in determining whether
amendments to this rule are appropriate after the conclusion of the comment
period.
This interim final rule is effective on 15 September 2025.
Comments must be received on or before 17 October 2025.
