## II. Background

EPA has granted emergency exemptions to the following State and Federal agencies. The emergency exemptions may take the following form: Crisis, public health, quarantine, or specific.

Under FIFRA section 18, EPA can authorize the use of a pesticide when emergency conditions exist. Authorizations (commonly called emergency exemptions) are granted to State and Federal agencies and are of four types:

1. A “specific exemption” authorizes use of a pesticide against specific pests on a limited acreage in a particular State. Most emergency exemptions are specific exemptions.

2. “Quarantine” and “public health” exemptions are emergency exemptions issued for quarantine or public health purposes. These are rarely requested.

3. A “crisis exemption” is initiated by a State or Federal agency (and is confirmed by EPA) when there is insufficient time to request and obtain EPA permission for use of a pesticide in an emergency.

EPA may deny an emergency exemption: If the State or Federal agency cannot demonstrate that an emergency exists, if the use poses unacceptable risks to the environment, or if EPA cannot reach a conclusion that the proposed pesticide use is likely to result in “a reasonable certainty of no harm” to human health, including exposure of residues of the pesticide to infants and children.

                    If the emergency use of the pesticide on a food or feed commodity would result in pesticide chemical residues, EPA establishes a time-limited tolerance                           ( print page 52949)                        meeting the “reasonable certainty of no harm standard” of the Federal Food, Drug, and Cosmetic Act (FFDCA).                

                    In this document: EPA identifies the State or Federal agency granted the exemption, the type of exemption, the pesticide authorized and the pests, the crop or use for which authorized, number of acres (if applicable), and the duration of the exemption. EPA also gives the                     **Federal Register**                     citation for the time-limited tolerance, if any.

*Specific Exemption:*                     EPA authorized the use of hop beta acids in beehives to control varroa mite; March 8, 2011 to December 31, 2011. Since this request proposed the use of a new chemical, which has not been registered by EPA, a notice of receipt published in the                     **Federal Register**                     on November 17, 2010 (75 FR 70236) with the public comment period closing on December 2, 2010. This request was also granted to CA, CO, GA, HI, ID, IA, LA, MD, MN, MS, NE, ND, OR, TX, WA, WV, WY because the varroa mite is a highly destructive pest and is having a catastrophic effect on honey bee populations. The parasitic mite is considered the primary pest of honeybees and its control is necessary for successful beekeeping. Further, currently available registered products no longer successfully control varroa mites because repeated use has contributed to widespread development of mite resistance.                     *Contact:*                     Stacey Groce.

                    EPA authorized the use of spirotetramat on onion, dry bulb to control thrips; March 8, 2011 to September 30, 2011.                     *Contact:*                     Keri Grinstead.                

                    EPA authorized the use of kasugamycin on apple to control fire blight; April 6, 2011 to April 1, 2012. Since the applicant proposed the use of a new chemical which has not been registered by the EPA, a Notice of Receipt was published in the                     **Federal Register**                     on March 2, 2011 (76 FR 11454). The rationale for emergency approval of this use is that kasugamycin is needed to control streptomycin-resistant strains of                     *Erwinia amylovora,*                     the causal pathogen of fire blight, due to the lack of available alternatives and effective control practices. Without the use of kasugamycin and if weather conditions are present which favor a fire blight disease epidemic, it is likely that Michigan apple growers could suffer 50% yield losses.                     *Contact:*                     Keri Grinstead.

                    EPA authorized the use of sprirotetramat on onion, dry bulb, to control thrips; July 12, 2010 to September 15, 2010. Since this request proposed the use of a chemical whose registration had been canceled, a Notice of Receipt was published in the                     **Federal Register**                     on July 30, 2010 (75 FR 44946). The rationale for emergency approval of this use is that onion thrips are sucking insects which both directly damage the crop and also vector the plant disease Iris Yellow Spot Virus. The use of spirotetramat is necessary to ensure thrips control in areas experiencing thrips resistance to available alternatives and, in particular, where 6-8 seasonal applications of alternative pesticides are required to achieve adequate control.                     *Contact:*                     Keri Grinstead.

                    EPA authorized the use of fipronil on turnip and rutabaga to control cabbage maggot. Since this request proposed a use which is IR4-supported, has been requested in 5 or more previous years, and a petition for tolerance has not been submitted to the Agency, a Notice of Receipt was published in the                     **Federal Register**                     on April 6, 2011 (76 FR 19093). The rationale for emergency approval of this use is that no pesticides or practices are currently available for use in turnip and rutabaga, to provide adequate control of cabbage maggots. If not controlled, this insect pest is expected to cause significant yield and economic losses due to their damaging effects from feeding on the turnip and rutabaga roots.

                    EPA authorized the use of dinotefuran on rice to control rice stink bug (Oebalus pugnax); April 5, 2011, to October 30, 2011. Since this request proposed a use which has been requested in 3 or more previous years, and a petition for tolerance has not yet been submitted to the Agency a notice of receipt published in the                     **Federal Register**                     on March 2, 2011 (76 FR 11453) with the public comment period closing on March 17, 2011. This request was granted because the Applicant demonstrated that rice stink bug resistance is occurring in several areas. In addition, the current weather conditions are contributing to urgent and non-routine pest problems. Rice growers would likely incur a significant economic loss without use of dinotefuran.                     *Contact:*                     Libby Pemberton.

                    EPA authorized the use of diflubenzuron in alfalfa for control of various grasshopper and cricket species. Since this request proposed a use which is IR4-supported, has been requested in 5 or more previous years, and a petition for tolerance has not been submitted to the Agency, a Notice of Receipt was published in the                     **Federal Register**                     on April 6, 2011 (76 FR 19092). The rationale for emergency approval of this use is that higher than normal populations of these insect pests were anticipated based upon early surveys, and available control practices and pesticides would not provide adequate control under the extreme outbreak conditions. Additionally, other pesticides available posed higher risk to beneficial and pollinator insects. Adequate control of the outbreak was needed to avert significant economic losses from the damaging feeding activities of these species.
