This final rule revokes specific tolerances for the herbicides glyphosate and linuron, and the insecticides fenbutatin oxide (hexakis (2-methyl-2-phenylpropyl)distannoxane) and mevinphos (methyl 3- [(dimethoxyphosphinyl)oxy]butenoate, alpha and beta isomers). EPA is revoking these tolerances because the Agency has canceled the food uses associated with them. All registrations for mevinphos were canceled in 1994. These revocations were proposed in the Federal Register, as given in the regulatory text. The regulatory actions in this document are part of the Agency's reregistration program under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and the tolerance reassessment requirements of the Federal Food, Drug, and Cosmetic Act (FFDCA). By law, EPA is required to reassess 33% of the tolerances in existence on August 2, 1996, by August 1999, or about 3,200 tolerances. This document revokes 58 tolerances and/or exemptions. Since 3 tolerances were previously reassessed, 55 of the 58 revocations are counted here as reassessments made toward the August, 1999 review deadline of FFDCA section 408(q), as amended by the Food Quality Protection Act (FQPA) of 1996.
