EPA Seeks Comment on Draft Guidance for Nanoscale Materials Reporting Rule

The U.S. Environmental Protection Agency (EPA) published a Federal Register notice on May 16, 2017, announcing the availability of and requesting public comment on a draft guidance document entitled “Guidance on EPA’s Section 8(a) Information Gathering Rule on Nanomaterials in Commerce.”  82 Fed. Reg. 22452.  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 Toxic Substances Control Act (TSCA) Section 8(a) rule.  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.  More information regarding the final rule is available in our January 12, 2017, memorandum, “EPA Promulgates Final TSCA Reporting and Recordkeeping Rule for Nanoscale Materials.”  EPA states that it will accept comments regarding the draft guidance, but not regarding the rule itself, “which has already been finalized.”  Comments are due June 15, 2017.

The 14-page draft guidance, in the form of questions and answers, addresses questions within the following categories:  what chemicals are reportable; who is required to report; information that is to be reported; when is reporting required; general questions; and confidentiality.  While the publication of draft guidance within four months of promulgation of the final rule is an achievement, the draft guidance does not significantly expand upon that which is already known, or make the rule clearer or easier with which to comply.  Companies subject to the reporting requirements of the final rule can expect to continue to struggle in sorting out what discrete forms are required to be reported.  More information regarding the draft guidance is available in our May 16, 2017, memorandum, “EPA Seeks Comment on Draft Guidance for Nanoscale Materials Reporting Rule.”
