This final rule governs the establishment of time-limited tolerances and exemptions for residues of a pesticide chemical resulting from its emergency use as authorized under section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The purpose of this rule is to set into place a process that will ensure timely decisions on any tolerance related issue in response to a request for an emergency use of a pesticide chemical to be used in or on food or feed. Under this rule, EPA will implement the provisions of the Federal Food, Drug, and Cosmetic Act (FFDCA) related to FIFRA section 18 time-limited tolerances by evaluating each petition on a case-by-case basis to determine if adequate reliable data are available to make the required safety finding mandated under FFDCA section 408. This rule pertains only to regulatory changes resulting from the 1996 enactment of the Food Quality Protection Act (FQPA) which amended FFDCA.
