Potassium Titanium Oxide SNUR Bans Manufacture of Particle Size Less Than 100 nm

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 Opens Registration Review Docket for Nanosilver

On July 6, 2012, the U.S. Environmental Protection Agency (EPA) announced the establishment of a registration review docket for nanosilver. EPA states that registration review is its “periodic review of pesticide registrations to ensure that each pesticide continues to satisfy the statutory standard for registration, that is, the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment.” Registration review dockets...

EPA OIG Concludes EPA Needs to Manage Nanomaterials More Effectively

On December 30, 2011, the U.S. Environmental Protection Agency (EPA) Office of Inspector General (OIG) released a report entitled EPA Needs to Manage Nanomaterial Risks More Effectively. According to OIG, the purpose of its review was to determine how effectively EPA is managing the human health and environmental risks of nanomaterials. OIG states that it found “that EPA does not currently have sufficient information or processes to effectively manage the human health and...

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 Conditionally Registers Pesticide Product Containing Nanosilver As a New Active Ingredient

The U.S. Environmental Protection Agency (EPA) announced on December 1, 2011, that it is conditionally registering a pesticide product containing nanosilver as a new active ingredient. HeiQ AGS-20 is a silver-based antimicrobial pesticide product approved for use as a preservative for textiles.  The final registration is not yet in the docket.  We believe, but cannot confirm, the final registration is largely similar to the draft proposed registration issued last year. As...

NANO Act Promotes Development and Responsible Stewardship of Nanotechnology

Representative Mike Honda (D-CA) re-introduced on August 1, 2011, the Nanotechnology Advancement and New Opportunities Act (NANO Act), which seeks to promote the development and responsible stewardship of nanotechnology in the U.S. According to Rep. Honda, the legislation is designed to maintain the U.S.’s leadership role in nanotechnology research by promoting the development and commercialization of the results. At the same time, the NANO Act addresses concerns raised about the potential...

Comment Deadline Approaches for EPA’s Policy on Nanoscale Materials in Pesticide Products

Comments on the U.S. Environmental Protection Agency’s (EPA) proposed policy on nanoscale materials in pesticide products are due August 17, 2011. EPA offers two approaches for obtaining the information EPA believes it needs concerning nanoscale materials in pesticide products. Under the first approach, EPA would use Section 6(a)(2) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to obtain information regarding what nanoscale material is present in a registered pesticide...

EPA Proposes Policy on Nanoscale Materials in Pesticide Products

The U.S. Enviromental Protection Agency (EPA) published in the June 17, 2011, Federal Register a notice describing several possible approaches for obtaining certain additional information on the composition of pesticide products. EPA focuses particularly on information about what nanoscale materials are present in registered pesticide products, and defines “nanoscale material” as “an active or inert ingredient and any component parts thereof intentionally produced to have at least one...
