EPA Promulgates SNUR for Functionalized Carbon Nanotubes (Generic)

On October 27, 2014, the U.S. Environmental Protection Agency (EPA) promulgated significant new use rules (SNUR) for 52 chemical substances, including “functionalized carbon nanotubes (generic).” According to the Federal Register notice, the premanufacture notice (PMN) states that the substance will be used as a thin film for electronic device applications. The notice states that, as described in the PMN, EPA “does not expect significant occupational exposures due to the use of impervious gloves, where there is potential for dermal exposure, and because the PMN is used in liquid form and is not spray applied.” In addition, EPA does not expect environmental releases during the use identified in the PMN submission. EPA states that it has determined, however, “that any use of the substance without the use of impervious gloves, where there is a potential for dermal exposure; manufacturing the PMN substance for use other than as a thin film for electronic device applications; manufacturing, processing, or using the PMN substance in a form other than a liquid; use of the PMN substance involving an application method that generates a mist, vapor, or aerosol; or any release of the PMN substance into surface waters may cause serious health effects or significant adverse environmental effects.” The rule is effective on December 26, 2014. Written adverse or critical comments, or notice of intent to submit adverse or critical comments, must be received by November 26, 2014.
