II. What Action is the Agency Taking?

EPA is providing an opportunity for public comment on a petition received from the World Wildlife Fund (WWF) that asks the Agency to suspend the registration of Rozol Prairie Dog Bait (EPA Reg. No. 7173-286) and cancel certain application sites for the product. This product is currently registered for use to control black-tailed prairie dogs and its active ingredient is the anticoagulant rodenticide chlorophacinone.

The primary basis for the petition is the potential effect of this product on non-target species, including certain predators and scavengers of the black-tailed prairie dog. Specifically, the petition contends that the poisoning risks to non-target species from the use of this product are unjustified, given the availability of alternative products to control black-tailed prairie dogs. Petitioners request EPA to require the completion of an Avian Reproduction Study before further product use to control black-tailed prairie dogs is permitted. The petition also asks EPA to initiate formal consultation, under section 7 of the Endangered Species Act, with the U.S. Fish and Wildlife Service (FWS) regarding the registration of this product. Third, it requests that EPA develop a memorandum of understanding with FWS to show how EPA will promote the conservation of birds protected under the Migratory Bird Treaty Act. Petitioners ask that EPA suspend the use of Rozol Prairie Dog Bait while these activities are ongoing and also request that the application of the product be prohibited in those counties where black-footed ferrets are present.

As additional background, EPA is providing a recent letters from FWS and other interested parties expressing similar concerns about the potential impact of Rozol Prairie Dog Bait on non-target wildlife protected under the Endangered Species Act and the Migratory Bird Treaty Act (available in the public docket accompanying this notice at EPA-HQ-OPP-2009-0684).

EPA regulates non-food use pesticides, such as Rozol Prairie Dog Bait, under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Under FIFRA, EPA registers a pesticide if it determines that the use of the pesticide will not cause “unreasonable adverse effects” to human health or the environment. This standard involves risk-benefit balancing when risks exist above EPA's level of concern. Both registration decision under section 3 of FIFRA and cancellation decisions under section 6 of FIFRA depend on the outcome of adverse effects determinations. If this adverse effects standard is not satisfied, EPA may not register the pesticide and existing pesticides are subject to cancelation. See FIFRA sections 3(c)(5) and 6(b).

If EPA issues a notice of intent to cancel a pesticide registration and further determines that a suspension of the registration prior to the completion of the ensuing cancellation proceedings is necessary to prevent an imminent hazard, EPA may take steps to suspend the registration during the pendency of cancellation proceedings, as described in section 6(c) of FIFRA. FIFRA defines an “imminent hazard” as a situation in which the continued use of a pesticide, during the time required for a cancellation hearing, would likely cause unreasonable adverse effects or will involve an unreasonable hazard to the survival of a species listed as threatened or endangered pursuant to the Endangered Species Act.

WWF's petition requests both suspension of the registration for Rozol Prairie Dog Bait and cancellation of certain application sites for the product. EPA therefore anticipates that its response to the petition will address its risk-benefit analysis for this pesticide. EPA conducted such an analysis at the time it registered Rozol Prairie Dog Bait under section 3 of FIFRA. For this notice, EPA has compiled a list of topics relevant to EPA's risk-benefit balancing decision for Rozol Prairie Dog Bait (available in the public docket accompanying this topic at EPA-HQ-OPP-2009-0684). EPA is providing an opportunity for public comment and the submission of additional information pertinent to these topics (if any is available), as such information would further assist the Agency in responding to the petition.
