On March 25, 2015, the U.S. Environmental Protection Agency (EPA) issued a prepublication version of a Toxic Substances Control Act (TSCA) Section 8(a) proposed rule concerning reporting and recordkeeping requirements for certain chemical substances when manufactured (including imported) or processed at the nanoscale. EPA proposes to require persons that manufacture or process these chemical substances to report electronically to EPA certain information, including the specific chemical identity, production volume, methods of manufacture and processing, exposure and release information, and existing data concerning environmental and health effects. EPA also proposes to require any persons who intend to manufacture or process chemical substances as discrete nanoscale materials after the effective date of the final rule to notify EPA of the same information at least 135 days before the intended date of commencement of manufacture or processing. Comments will be due 90 days after the proposed rule is published in the Federal Register. EPA has posted a fact sheet on its website. EPA states that it anticipates holding a public meeting during the comment period, and it will announce the time and place of the meeting on its web page. More information is available in Bergeson & Campbell, P.C.’s March 25, 2015, memorandum.
