Lynn L. Bergeson, “EPA Proposes New Use Rules:  Proposal could limit the use of 14 nanoscale substances,” Chemical Processing, January 2012.

The US Environmental Protection Agency (EPA) proposed on December 28, 2011, significant new use rules (SNURs) for 17 chemical substances that were the subject of premanufacture notices (PMN), including seven substances with the term carbon nanotube (CNT) and seven substances with the term fullerene in their respective names. These 14 substances are subject to consent orders under Section 5(e) of the Toxic Substances Control Act (TSCA). This column provides background on, and the implications of, these proposed SNURs.
