EPA Regulatory Agenda Includes Item on Nanoscale Materials Stewardship Program

Lynn L. Bergeson

According to a notice in the U.S. Environmental Protection Agency’s (EPA) November 24, 2008, Regulatory Agenda, EPA intends to publish an interim evaluation in March 2009 of the Nanoscale Materials Stewardship Program (NMSP), and a final evaluation of the NMSP, including next steps, in April 2010. The NMSP is a voluntary program that EPA established to assemble existing data and information from manufacturers and processors of certain nanoscale materials. The notice states that, under the Toxic Substances Control Act (TSCA), EPA has the authority to require the development of data necessary for risk assessment when statutory findings concerning (1) production volume and exposure/entry into the environment or (2) potential hazard can be made, and to prevent and eliminate unreasonable risk of injury to human health and the environment.
