# Nanoscale Materials Stewardship Program

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more. EPA's voluntary Nanoscale Materials Stewardship Program (NMSP) ended in December 2009. The Agency released its Interim Report on the NMSP (PDF) (38 pp, 872K) in January 2009 and will issue a final report in 2010. Although the NMSP provided EPA with useful information regarding a limited number of nanoscale materials in commerce, a significant number of the environmental health and safety data gaps remain. To address these gaps and prevent potential risks that may be posed by nanoscale materials, EPA is taking a number of regulatory actions under the Toxic Substances Control Act. 

### Background In October 2006, EPA launched a collaborative public process to design and develop this stewardship program. On July 12, 2007, EPA announced the availability for public comment of: Concept paper (PDF) (21 pp, 165K) that outlined the Agency's initial thinking on the design and development of the NMSP; NMSP Information Collection Request (PDF) (25 pp, 101K); TSCA Inventory Status of Nanoscale Substances

– General Approach (2007) (PDF) (7 pp, 39K) that described EPA's initial thinking regarding whether a nanoscale material is a "new" or "existing" chemical substance under TSCA. EPA held a public meeting (PDF) (35 pp, 119K) on August 2, 2007, to obtain additional input on the NMSP and related documents. EPA finalized the design and format of the NMSP based on written public comments, comments received at the public meeting, and scientific peer consultations on risk management practices (PDF) (75 pp, 464K) in October 2006, and on material characterization (PDF) (83 pp, 601K) in September 2007. On January 28, 2008, EPA announced the final NMSP and invited interested parties to participate in the program. The NMSP had two parts: 1. Basic Program for reporting available information on engineered nanoscale materials that were manufactured, imported, processed or used; and 2. In-depth Program to voluntarily develop data, including testing, over a longer time frame. More Information Read about Control of Nanoscale Materials under the Toxic Substances Control Act.
