On October 16, 2018, the Environmental Protection Agency (EPA) issued a proposed rule that would establish Significant New Use Rules (SNURs) under the Toxic Substances Control Act (TSCA) for 13 chemical substances for which premanufacture notices (PMNs) have been approved during the two years since the statute was amended. A total of 6 SNURs were proposed for these 13 substances. Unlike other recent SNURs enacted after TSCA was amended, the 13 chemical substances are not also subject to consent orders. Indeed, all previously proposed and final SNURs for PMNs under amended TSCA were for substances for which EPA had previously negotiated orders under TSCA Section 5(e).
The proposed SNURs would require that persons who intend to manufacture (including import) or process any of the 13 chemical substances for an activity that is designated as a significant new use submit a “Significant New Use Notice” to EPA at least 90 days before commencing that activity. And, consistent with the SNUR regulations at 40 CFR § 721.25, the proposed rule states that persons may not commence the manufacture or processing for the significant new use until EPA has conducted a review of the notice and decided on the notice, and the person has taken any actions as are required as a result of that determination. Comments on the proposed SNURs are due November 15, 2018.
