This rule revokes tolerances for pesticide residues in or on livestock feed commodities that have been deleted from the list of significant livestock feed commodities in Table I of Pesticide Assessment Guideline 860.1000. In implementing the Federal Food, Drug, and Cosmetic Act (FFDCA), EPA does not require data on or set individual tolerance levels for minor, non-significant livestock animal commodities. As explained in this document, EPA considers residues in minor, non-significant livestock feed commodities to be covered by the tolerances for the pesticide on the principal commodities of a crop. DATES: This final rule becomes effective January 16, 1998. Written objections and requests for hearing must be received by February 17, 1998.
