Lynn L. Bergeson, “EPA Promulgates SNUR For Functionalized Multi-Walled Carbon Nanotubes,” Nanotechnology Now, May 22, 2013.

On May 9, 2013, the U.S. Environmental Protection Agency (EPA) promulgated a significant new use rule (SNUR) for premanufacture notice (PMN) substance P-12-44, which is identified as “functionalized multi-walled carbon nanotubes.” According to the Federal Register notice, “[t]he PMN states that the generic (non-confidential) use of the substance is as an additive for rubber and batteries.” EPA states that it determined that “use of the substance other than as described in the PMN; manufacturing, processing, or use in a powder form; or any use of the substance resulting in surface water releases may cause serious health effects or significant adverse environmental effects.”
