Nanoscale Materials Stewardship Program

See Chapter 2, TSCA s Scope for a discussion of the status of nonmaterial under TSCA. 

In January 2009 EPA issued an interim assessment of the NMSP. It called the basic phase of the program a success, although it did not receive enough information to determine the molecular identity of many of the nanoscale materials that were the subject of the submissions. The EPA noted that it received 123 submissions on 58 different chemicals. Because there is no inventory of nanoscale materials EPA devoted considerable effort to estimating how many commercial nanomaterials are currently made in order to determine if there was a gap between the number of commercial nanomaterials and the number of commercial nanomaterials that were the subject of NMSP reporting. It estimated that NMSP participants reported on only approximately one-third of the chemicals from which commercially available nanomaterials are made, and only approximately one-tenth of the commercially available nanomaterials, which may be composed of multiple chemicals.

EPA Nanoscale Materials Stewardship Program. EPA has implemented a voluntary Nanoscale Materials Stewardship Program (NMSP) under the Toxic Substances Control Act (TSCA), which is intended to "complement and support its efforts on new and existing nanoscale materials.EPA indicates that, based on the outcomes of an extensive review process, the general components of the Stewardship Program could include ...
