On December 7, 2016, the U.S. Environmental Protection Agency (EPA) announced it would be issuing a rule proposing to prohibit the manufacture, processing, and distribution in commerce of trichloroethylene (TCE) for certain uses under Section 6 of the Toxic Substances Control Act (TSCA), due to its determination that there are significant health risks associated with TCE use in aerosol degreasing and for spot cleaning in dry cleaning facilities. The proposed action is significant for several reasons, including that it represents the first use in a very long time of TSCA Section 6 as well as the first Section 6 control action taken under new TSCA. Specifically, EPA is proposing to prohibit the use of TCE in “aerosol degreasing and for use in spot cleaning in dry cleaning facilities; to prohibit commercial use of TCE for aerosol degreasing and for spot cleaning in dry cleaning facilities; to require manufacturers, processors, and distributors, except for retailers of TCE for any use, to provide downstream notification of these prohibitions throughout the supply chain; and to require limited recordkeeping.” We look forward to a close reading of the proposed rule and to evaluating the arguments, the policy points, and the evidence provided by EPA to satisfy the various legal requirements, including those under Section 6(c) and Section 26.
EPA’s online Fact Sheet on TCE lists questions and answers as related to the proposed rule. In response to Question 3, What are the potential risks of TCE to people?, EPA states that its 2014 risk assessment found TCE to be “carcinogenic to people through all routes of exposure, which include inhalation, dermal (skin), and ingestion.” The pre-publication of the proposed rule is available on EPA’s website. Once it has been published in the Federal Register, comments must be submitted within 60 days of publication.
