Start Preamble


Environmental Protection Agency (EPA).




This notice announces EPA's intention to modify certain risk mitigation measures that were imposed as a result of the 2006 Reregistration Eligibility Decision (RED) for the pesticide permethrin. EPA conducted this reassessment of the permethrin RED in response to public comments received. In response to the commentors and continuing efforts to mitigate risk, the Agency has made several modifications to the permethrin RED label requirements including: Clarification of application rates to mushroom houses; revised droplet sizes for wide area mosquito abatement products; and mandatory label statements for canine spot-on products, pre-construction termiticide applications, and spray drift language for agricultural products. Additionally, the Agency has revised the data requirements and added a statement to Section IV of the RED to address concerns regarding the residential use of outdoor pesticide misting systems.

II. Background

What Action is the Agency Taking?

Under section 4 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is reevaluating existing pesticides to ensure that they meet current scientific and regulatory standards. In 2006, EPA issued a RED for permethrin under section 4(g)(2)(A) of FIFRA. In response to a notice of availability published in the Federal Register on June 28, 2006 (71 FR 36788) (FRL-8074-5), the Agency received substantive comments from the technical registrant and other commentors. The Agency's response to these comments is available for viewing in the public docket. The amended permethrin RED reflects changes resulting from these comments as well as subsequent efforts by the Agency to mitigate overall risk.

III. What Does this Amendment Do?

The amended permethrin RED reflects revisions resulting from Agency consideration of public comments to the RED and efforts to develop standardized label language for certain applications. The label table incorporated into the permethrin RED amendment includes modifications which provide mandatory label language for canine spot-on Start Printed Page 10434products, pre-construction termiticide applications, and spray drift language for agricultural products; clarification of application rates to mushroom houses; and revised droplet sizes for wide area mosquito abatement products.

In addition, to address concerns regarding the residential use of outdoor pesticide misting systems, the following statement has been added to the permethrin RED: “The Agency has developed an Outdoor Residential Misting System web-based fact sheet page designed to help consumers decide if these systems are appropriate for their home, understand safety precautions about using outdoor misting systems, find related information on Integrated Pest Management, and understand the role of the US EPA and state agencies in regulating misters.”

Also, the permethrin RED has been amended to reflect the Agency's determination that efficacy data is required for the following product groups which claim to target public health pests: Outdoor residential misting systems, permethrin impregnated clothing products, and permethrin products used on domestic animals. The generic data call-in requirements have also been revised to exclude the following confirmatory studies which the Agency has determined are not required: Whole sediment acute toxicity for freshwater and estuarine/marine invertebrates, directions for use, and enforcement analytical method for animals.
