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 include information intended to assist the public in understanding the types of information and issues that EPA may consider during the course of registration reviews. According to the preliminary work plan, EPA has information that there are silver-based pesticide products that were registered without the registrant disclosing to EPA the presence or characteristics of the nanosilver in their products. EPA sent a letter in August 2009 to each registrant with silver-based products requesting a statement as to whether their products contained any amount of silver in any form having a dimension that measures between 1 and approximately 100 nanometers. Four registrants responded that their products, which were registered using data for conventional silver, contain nanosilver. In the preliminary work plan, EPA states it is identifying several other products, registered using data for silver chloride, as potentially containing nanosilver. The registration review for nanosilver includes these products, as well as the two HeiQ nanosilver products conditionally registered in December 2011. According to the preliminary work plan, EPA believes that additional data are needed to determine whether the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) standard for maintaining these registrations is met “due to nanosilver’s unique physical and chemical properties, and thus nanosilver’s potentially different health and safety properties as compared to silver.”

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 environmental risks of nanomaterials.” According to OIG, although EPA has the statutory authority to regulate nanomaterials, it “currently lacks the environmental and human health exposure and toxicological data to do so effectively.” EPA proposed a policy, under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), that would identify new pesticides being registered with nanoscale materials.  After “minimal industry participation” in EPA’s Nanoscale Materials Stewardship Program (NMSP), a voluntary data collection program, EPA has chosen to propose mandatory reporting rules for nanomaterials under FIFRA, and is developing proposed rules under the Toxic Substances Control Act (TSCA).

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 members of the nano community know well, this is very good news and demonstrates that EPA is prepared to make regulatory decisions involving nanotechnology, even where, as here, they are likely to inspire controversy.

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 product and its potential effects on humans or the environment. EPA states that it would “prefer” to use this approach, despite industry’s concern over the use of the “adverse effects” reporting provision to obtain information. Under the second approach, EPA would use a data call-in (DCI) under FIFRA Section 3(c)(2)(B). EPA also proposes to apply an initial presumption that active and inert ingredients that are the nanoscale versions of non-nanoscale active and inert ingredients already present in registered pesticide products are potentially different from those conventionally sized counterparts. Registrants could rebut this initial presumption on a case-by-case basis.

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 …

The U.S. Environmental Protection Agency (EPA) released on June 9, 2011, a pre-publication copy of a forthcoming Federal Register 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 …

On December 15, 2010, the U.S. Environmental Protection Agency (EPA) announced that it fined Kinetic Solutions Inc., doing business as Rabbit Air, $82,400 for allegedly selling unregistered and misbranded pesticides and making unproven claims about their effectiveness. According to EPA, Kinetic Solutions Inc. made illegal public health claims for its air purifier branded “Nano Silver Pre …

NanoBusiness Alliance included Lynn L. Bergeson in its recent interview series. The interview covers a wide range of issues related to nanotech environmental, health and safety, including such “hot” topics as establishing a nano nomenclature that is uniform, thoughtful, and useful for regulatory purposes; the U.S. Environmental Protection Agency’s (EPA) three Toxic Substances Control Act (TSCA) …

The State Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Research and Evaluation Group (SFIREG) Pesticide Operations and Management (POM) Committee held a meeting on September 20, 2010. During the meeting, Jennifer McLain, Associate Director of the Antimicrobials Division, U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs (OPP), provided an update on EPA’s regulation of pesticides …

According to the Office of Management and Budget (OMB) website, on July 30, 2010, OMB received from the U.S. Environmental Protection Agency (EPA) a notice concerning “Pesticide Products Containing Nanoscale Materials.” No additional information regarding the notice is available on OMB’s website. During the April 29, 2010, meeting of EPA’s Pesticide Program Dialogue Committee (PPDC), William Jordan, …
