EPA Intends to Promulgate Final TSCA 8(a) Rule in October 2016

According to an item in the U.S. Environmental Protection Agency’s (EPA) Fall 2015 Regulatory Agenda, EPA intends to promulgate a final Toxic Substances Control Act (TSCA) Section 8(a) rule in October 2016 concerning reporting and recordkeeping requirements for certain chemical substances when they are manufactured or processed at the nanoscale.  EPA’s April 6, 2015, proposed rule includes one-time reporting for existing nanoscale materials and one-time reporting for new discrete nanoscale materials before they are manufactured or processed.  EPA states that consistent with the President’s memorandum for Executive Agencies regarding Principles for Regulation and Oversight of Emerging Technologies, the proposed rule would facilitate assessment of risks and risk management, examination of the benefits and costs of further measures, and making future decisions based on available scientific evidence.
