EPA Invites Public Comment on Design of Nanotechnology Stewardship Program


In its continuing efforts to better understand the potential risks and benefits of nanotechnology, EPA is inviting the public to comment on the agency’s proposed approach to developing a Nanoscale Materials Stewardship Program (NMSP). EPA’s approach will increase the scientific understanding and ensure appropriate oversight of nanoscale industrial chemicals to facilitate the responsible development of this growing technology.

The effort will call on manufacturers of engineered nanoscale chemical materials to develop and report key information needed on these materials to help ensure the safe manufacture and use of the products of nanotechnology. This program will complement and support EPA’s new and existing chemical programs under Toxic Substances Control Act (TSCA).

The NMSP proposes to cover, but is not limited to, existing chemical nanoscale materials manufactured or imported for commercial purposes as defined by TSCA. The NMSP will also help to provide a firmer, scientific foundation for regulatory decisions by encouraging the development of key scientific information and use of a basic set of risk management practices in developing and commercializing nanoscale materials. EPA is seeking comment on a concept paper for the NMSP and the Information Collection Request (ICR) for the program.

EPA is also seeking comment on a document outlining its current approach for determining whether a nanoscale material is a “new” or “existing” chemical substance under TSCA. Manufacturers and importers of nanoscale materials that meet the definition of “chemical substances” under TSCA are subject to different requirements and reporting depending on whether they are considered “new” or “existing” chemicals.
