EPA issues interim final rule extending certain compliance dates under the TSCA trichloroethylene (TCE) risk management rule

EPA issued an interim final rule under TSCA section 6 risk management for trichloroethylene (TCE) that extends certain compliance dates. The update affects specific TCE prohibitions (including a use as a processing aid in nuclear fuel manufacturing) and extends a prohibition related to disposal of TCE to wastewater, and also adjusts the downstream notification timeline (e.g., allowing a set period after publication of the final rule for notification changes). Compliance teams using or disposing of TCE in these affected scenarios should reassess internal phase-out plans, wastewater/disposal controls, supplier/customer notifications, and any related contract and SDS/labeling workflows to align with the extended timelines and any interim final rule conditions.
