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 is designated in the SNUR as a significant new use to notify EPA at least 90 days before commencing that...

EPA Promulgates SNUR for Polymer of Terephthalic Acid and Ethyl Benzene with Multi-Walled Carbon Nanotube (Generic)
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 a Toxic Substances Control Act (TSCA) Section 5(e) consent order. The consent order requires the following...
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 comments on the direct final SNURs. EPA intends to publish proposed SNURs for the chemical substances in the notice....
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: Nanoscale Materials; Chemical Substances When Manufactured, Imported, or Processed as Nanoscale Materials; Reporting and Recordkeeping Requirements; Significant New Use Rule: EPA is developing a proposal to establish reporting...
On October 5, 2012, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) for potassium titanium oxide, which was previously the subject of a consent order under Section 5(e) of the Toxic Substances Control Act (TSCA). EPA states that, based on test data on the premanufacture notice (PMN) substance and structure activity relationship analysis of test data on analogous respirable, poorly soluble particulates (subcategory titanium dioxide), EPA...

EPA Promulgates SNUR for Infused Carbon Nanostructures
On April 4, 2012, the U.S. Environmental Protection Agency (EPA) promulgated, through a direct final rule, significant new use rules (SNUR) for 17 chemical substances that were the subject of premanufacture notices (PMN). This includes a SNUR for “infused carbon nanostructures (generic).” According to EPA, the PMN states that the generic (non-confidential) use of the substance is as an additive to provide conductive properties to reinforcements used in composites. EPA states that, based...

EPA Publishes Proposed SNURs for CNTs
The U.S. Environmental Protection Agency (EPA) published on December 28, 2011, proposed significant new use rules (SNUR) for 17 chemical substances that were the subject of premanufacture notices (PMN). Of particular interest, seven of the PMN substances’ reported chemical names include the term “carbon nanotube” (CNT) or “CNT.” EPA states that because of a lack of established nomenclature for CNTs, the Toxic Substances Control Act (TSCA) Inventory names for CNTs are...
The U.S. Environmental Protection Agency’s (EPA) July 7, 2011, Regulatory Agenda includes several notices concerning nanoscale materials:...
On May 6, 2011, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified generically as multi-walled carbon nanotubes (MWCNT), which was the subject of premanufacture notice (PMN) P-08-199. Under the final SNUR, persons intending to manufacture, import, or process MWCNT for a use that is designated as a significant new use by the final rule must...
