Reg. 22978.  EPA is required to do so per TSCA Section 5(g) after its review of TSCA Section 5(a) notices when it makes a finding that a new chemical substance or significant new...

The U.S. Environmental Protection Agency (EPA) recently announced, in two separate notices, that it is initiating a process to revise (1) certain requirements in the Agricultural Worker Protection Standard (WPS) (82 Fed. Reg. 60576 (Dec. 21. 2017)); and (2) to revise the minimum age requirements in the Certification of Pesticide Applicators (C&T) rule.  82 Fed. Reg. 60195 (Dec. 19. 2017). For the WPS rulemaking, the provisions at issue were identified as part of the...

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...

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...

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...

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...
