proposed rule acephate chlorpyrifos fenbutatin-oxide hexakis metolachlor mcpa pyrethrins and triallate proposed tolerance actions by means of this proposed rule epa proposes transferring tolerances for the combined residues free and bound of the herbicide metolachlor in or on barley grain at 0.1 barley straw at 0.5 ppm buckwheat grain at 0.1 ppm millet fodder at 0.5 ppm millet forage at 0.5 ppm millet grain at 0.1 ppm oat forage 0.5 ppm oat grain at 0.1 ppm oat straw at 0.5 ppm rice grain at 0.1 ppm rice straw at 0.5 ppm rye forage 0.5 ppm rye grain at 0.1 ppm rye straw at 0.5 ppm wheat forage at 0.5 ppm wheat grain at 0.1 ppm and wheat straw at 0.5 ppm decreasing and revising nongrass animal feed forage fodder straw and hay grou 18 from 3.0 to animal feed nongrass grou 18 at 1.0 ppm revising millet fodder to millet straw. epa proposes increasing the tolerances for the combined metolachlor residues of concern in on cattle fat goat fat horse fat and sheep fat from 0.02 to 0.04 ppm cattle liver goat liver horse liver and sheep liver from 0.05 to 0.10 ppm cattle meat goat meat horse meat and sheep meat from 0.02 to 0.04 ppm cattle meat byproducts except kidney and liver goat meat byproducts except kidney and liver horse meat byproducts except kidney and liver and sheep meat byproducts except kidney and liver from 0.02 to 0.04 ppm egg poultry fat poultry meat and poultry meat byproducts except liver from 0.02 to 0.04 ppm revoking poultry liver at 0.05 ppm and revising poultry meat byproducts except liver to poultry meat byproducts. the agency determined that the increased tolerances are safe i.e. there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue. epa proposes revoking the tolerances for the combined residues of metolachlor in on cabbage at 1.0 ppm celery at 0.1 ppm fruit stone grou 12 at 0.1 ppm bell pepper at 0.1 ppm milo fodder 0.5 ppm milo forage at 0.5 ppm milo grain at 0.1 ppm peanut forage at 30 ppm and rice forage at 0.5 ppm. epa proposes decreasing the tolerances for the combined residues of metolachlor in on corn fodder from 8.0 to 6.0 ppm corn forage from 8.0 to 6.0 ppm peanut from 0.5 to 0.20 ppm and peanut hay from 30 to 20.0 ppm and sorghum forage from 2.0 to 1.0 ppm soybean forage from 8.0 to 5.0 ppm increasing sorghum fodder from 2.0 to 4.0 ppm and revising corn fodder to corn field stover and corn sweet stover corn forage to corn field forage and corn sweet forage corn grain to corn field grain sorghum forage to sorghum grain forage sorghum fodder to sorghum grain stover sorghum grain to sorghum grain grain and soybean to soybean seed. epa proposes decreasing and separating the tolerances for the combined metolachlor residues of concern from soybean forage and hay at 8.0 ppm to soybean forage at 5.0 ppm and soybean hay at 8.0 ppm. epa proposes revising the tolerances for the combined metolachlor residues of concern in on seed and pod vegetables except soybean at 0.3 ppm to vegetable legume edible podded subgrou 6a at 0.5 ppm pea and bean succulent shelled subgrou 6b at 0.3 ppm and pea and bean dried shelled subgrou 6c except soybean at 0.10 ppm. epa proposes establishing tolerances for the combined metolachlor residues of concern in on cotton gin byproducts at 4.0 ppm and peanut meal at 0.40 ppm. epa is revising commodity terminology to current agency practice. therefore epa proposes revising the tolerance from nongrass animal feed forage fodder straw hay grou 18 to animal feed nongrass grou 18 and revising the tolerance from vegetable fruiting grou 8 except tabasco pepper to vegetable fruiting grou 8 except nonbell pepper and onion dry bulb to onion bulb.
