On June 5, 2015, the U.S. Environmental Protection Agency (EPA) promulgated through a direct final rule significant new use rules (SNUR) for 22 chemical substances that were the subject of premanufacture notices (PMN), including graphene nanoplatelets having a predominant thickness of 1-10 layers with lateral dimension predominantly less than 2 microns (PMN Number P-14-763). This

On May 8, 2015, the U.S. Environmental Protection Agency (EPA) promulgated through a direct final rule significant new use rules (SNUR) for 25 chemical substances that were the subject of premanufacture notices (PMN).  The SNURs require persons who intend to manufacture (including import) or process any of these 25 chemical substances for an activity that

On February 2, 2015, the U.S. Environmental Protection Agency (EPA) promulgated through a direct final rule significant new use rules (SNURs) for 27 chemical substances that were the subject of premanufacture notices (PMNs).  The substances include polymer of terephthalic acid and ethyl benzene with multi-walled carbon nanotube (generic) (PMN Number P-13-573), which is subject to

According to a Federal Register notice scheduled for publication on December 23, 2014, the U.S. Environmental Protection Agency (EPA) is withdrawing several direct final significant new use rules (SNUR) promulgated on October 27, 2014, including one for functionalized carbon nanotubes (generic) (PMN No. P-13-793). EPA states that it received notice of intent to submit adverse

The U.S. Environmental Protection Agency (EPA) is scheduled to announce in the January 8, 2013, Federal Register the availability of its 2012 Regulatory Agenda. EPA’s Regulatory Agenda includes the following notice concerning nanoscale materials:
