# Cypermethrin; Response to Comments and Amendment to Reregistration Eligibility Decision; Notice of Availability
**AGENCY:**
Environmental Protection Agency (EPA).
**ACTION:**
Notice.
**SUMMARY:**
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 cypermethrin. EPA conducted this reassessment of the cypermethrin RED in response to public comments directed towards product labeling, risk mitigation, and the upcoming registration review process for pyrethroids, pyrethrins, and synergist chemicals. In response to the commenters and continuing efforts to mitigate risk, the Agency has made several modifications to the cypermethrin RED label requirements for pre-construction termiticide applications, spray drift language for agricultural products, and ventilation for total release foggers.

**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 cypermethrin under section 4(g)(2)(A) of FIFRA and the Agency received substantive comments. The Agency's response to these comments is available for viewing in the public docket. The amended cypermethrin 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 cypermethrin 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 cypermethrin RED amendment includes modifications which provide mandatory label language for pre-construction termiticide applications, spray drift language for agricultural products, and ventilation requirements for total release foggers.
