环保署拟延长三氯乙烯规则部分合规期限：化工加工等用途宽限至2027年底 意见征集至11月13日
华盛顿——美国环境保护署（EPA）本周在《联邦公报》发布拟议规则，拟延长其三氯乙烯（TCE）风险管理规则的部分合规期限。三氯乙烯是一种工业溶剂，EPA 于2024年12月发布针对该物质的风险管理规则，此后曾以临时最终规则延长过其他合规日期。
据美国工业卫生协会（AIHA）10月15日的摘要，新拟议规则将化工加工企业把 TCE 用作反应物或中间体、加工助剂及相关处置的禁令合规日期延至2027年12月31日；下游告知义务的修订日期同步调整。另一处延期涉及制冷剂 HFC-134a 生产中把 TCE 用作中间体的淘汰步骤，期限由2027年6月7日延至2027年12月31日。
EPA 表示，拟议延期是为应对特定化工加工商与制冷剂制造商在合规日期上面临的实际困难。该拟议规则各方面的公众意见征集截至11月13日。

EPA Proposes Extending Some Trichloroethylene Rule Deadlines to End of 2027; Comments Due November 13
WASHINGTON — The U.S. Environmental Protection Agency (EPA) has published a proposed rule in the Federal Register that would extend some compliance dates in its risk-management rule for the industrial solvent trichloroethylene (TCE). EPA issued the TCE risk-management rule in December 2024 and previously extended other deadlines through a 2025 interim final rule.
According to the American Industrial Hygiene Association's (AIHA) October 15 summary, chemical processors would have until December 31, 2027, to comply with prohibitions on processing TCE as a reactant or intermediate, using it as a processing aid, and disposing of it from those uses, with the downstream-notification deadline aligned to the new date. A second extension would move a step in phasing out TCE as an intermediate in producing the refrigerant HFC-134a from June 7 to December 31, 2027.
EPA says the proposed extensions address ongoing compliance difficulties for certain chemical processors and refrigerant manufacturers. Public comments on all aspects of the proposed rule are due by November 13.
