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.

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.
