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 Extends Comment Period for Proposed SNURs
The U.S. Environmental Protection Agency (EPA) has announced that, in response to public comments, it will provide the public more time to comment on the 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 “the comment period is being...

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...

EPA Issues Final SNURs for Carbon Nanotubes
On September 17, 2010, the U.S. Environmental Protection Agency (EPA) issued final significant new use rules (SNUR) for two chemical substances that were the subject of premanufacture notices (PMN). The two chemical substances are identified generically as multi-walled carbon nanotubes (MWCNT) (PMN P08177) and single-walled carbon nanotubes (SWCNT) (PMN P08328). Persons who intend to manufacture, import, or process either of these substances for a use that is designated as a...

EPA Proposes SNURs for Carbon Nanotubes
On November 6, 2009, the U.S. Environmental Protection Agency (EPA) proposed significant new use rules (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for two chemical substances that were the subject of premanufacture notices (PMN). EPA identified the substances generically as multi-walled carbon nanotubes and single-walled carbon nanotubes. According to the notice, these substances are subject to TSCA Section 5(e) consent orders issued by EPA. The consent orders...

EPA Announces Receipt of CNT PMNs
In a January 5, 2009, Federal Register notice, the U.S. Environmental Protection Agency (EPA) announces receipt of several premanufacture notices (PMN) concerning multi-walled carbon nanotubes (CNT). Under Section 5 of the Toxic Substances Control Act (TSCA), EPA requires any person who intends to manufacture (defined by statute to include import) a new chemical (i.e., a chemical not on the TSCA Inventory) to notify EPA and comply with the statutory provisions pertaining to the...
