Section 166.25 - Agency review(a)General. The Agency will review all requests as expeditiously as possible, making every attempt to respond to requests prior to the time when the proposed use is needed. The Agency will review the application and other available data necessary to make a determination with respect to all of the following: (1) Whether an emergency condition exists or will exist;(2) The Agency's ability and intention to establish a time-limited tolerance(s) or exemption(s) from the requirement of a tolerance for any pesticide residues resulting from the authorized use, identifying the level of permissible residues in or on food or feed resulting from the proposed use;(3) The anticipated benefits to be derived from the proposed use; and(4) The potential risks to human health, endangered or threatened species, beneficial organisms, and the environment from the proposed use.(b)Criteria for approval. The Administrator may authorize a specific, public health, or quarantine exemption, based on the information available to the Agency, after: (1) He determines that: (i) An emergency condition exists;(ii) The use of the pesticide under the exemption will not cause unreasonable adverse effects on the environment;(iii) Registration of the pesticide use for which the exemption is requested has not been suspended under section 6(c) of the Act or cancelled following a notice under section 6(b) of the Act, unless the use is authorized in accordance with the provisions of §§ 164.130 through 164.133 of this chapter;(2) Giving due consideration to: (i) Whether the pesticide is reasonably likely to be used in compliance with the requirements imposed by the Agency under the exemption; and(ii) The progress which has been made toward registration of the proposed use, if a repeated specific or public health exemption is sought. It shall be presumed that if a complete application for registration of a use, which has been under a specific or public health exemption for any 3 previous years, or any 5 previous years if the use is supported for registration by the IR-4 program, has not been submitted, reasonable progress towards registration has not been made.51 FR 1902, Jan. 15, 1986, as amended at 71 FR 4511 , Jan. 27, 2006
