This final rule announces the revocation of exemptions from the requirement of tolerances for residues found in 40 CFR 180.1032 for formaldehyde or a mixture of methylene bispropionate and oxy(bismethylene) bispropionate in or on the grains of barley, corn, oats, sorghum, and wheat and the forages of alfalfa, Bermuda grass, bluegrass, brome grass, clover, cowpea hay, fescue, lespedeza, lupines, orchard grass, peanut hay, peavine hay, rye grass, soybean hay, sudan grass, timothy, and vetch from postharvest application use as a fungicide to treat animal feeds. This action is being taken because there are no registered uses for formaldehyde on these commodities. The regulatory actions in this notice 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 and exemptions in existence on August 2, 1996, by August 1999, or about 3,200 tolerances and exemptions. This document revokes 22 exemptions, which will be counted among reassessments made toward the August 1999 review deadline of FFDCA section 408(q), as amended by the Food Quality Protection Act (FQPA) of 1996.
