On June 1, 2017, in concert with industry partners, SEMI will host an information-sharing webcast concerning the new regulatory requirements for nanoscale materials under the Toxic Substances Control Act (TSCA). Jim Alwood, Program Manager in the U.S. Environmental Protection Agency’s (EPA) Chemical Control Division, will provide a summary and answer questions about the new TSCA Section 8(a) record-keeping and reporting requirements for nanoscale materials. The final rule requires one-time reporting for existing discrete forms of certain nanoscale materials, and a standing one-time reporting requirement for new discrete forms of certain nanoscale materials. Manufacturers, processors, and end-users of substances, chemicals, formulations, and mixtures considered to be nanoscale materials by EPA, are affected by the enacted regulation. As reported in our May 17, 2017, blog item, EPA is currently seeking comment on a draft guidance document entitled “Guidance on EPA’s Section 8(a) Information Gathering Rule on Nanomaterials in Commerce.” The promised guidance provides answers to questions EPA has received from manufacturers (includes importers) and processors of certain chemical substances when they are manufactured or processed at the nanoscale as described in the January 12, 2017, final rule. The industry partners for the SEMI webcast include the NanoBusiness Commercialization Association.
