GAO Report States That EPA Faces Challenges in Regulating Risk of Nanomaterials

According to a report released on June 25, 2010, by the U.S. Government Accountability Office (GAO), the U.S. Environmental Protection Agency (EPA) faces challenges in effectively regulating nanomaterials that may be released in air, water, and waste because EPA lacks the technology to monitor and characterize these materials, or the statutes include volume-based regulatory thresholds that may be too high for effectively regulating the production and disposal of nanomaterials. In...

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 Withdraws Final SNURs for CNTs

Today’s Federal Register includes a notice from the U.S. Environmental Protection Agency (EPA) withdrawing the June 24, 2009, final significant new use rules (SNUR) for multi- and single-walled carbon nanotubes (CNT). EPA states that it published the final SNURs using direct final rulemaking procedures. Because EPA received a notice of intent to submit adverse comments on the rules, it is withdrawing the SNURs for CNTs. The Federal Register notice does not identify the...

EPA Clarifies Final CNT SNURs

On July 28, 2009, the U.S. Environmental Protection Agency (EPA) clarified its June 24, 2009, final Significant New Use Rules (SNUR) for multi- and single-walled carbon nanotubes (CNT).  According to EPA, upon review of the final rule, stakeholders asked whether the SNURs applied to all types of CNTs.  EPA responded: This is not the case.  These SNURs only apply to the specific carbon nanotubes that were the subject of the premanufacture notices (PMN)...
