proposed rule. captan 2 4-d dodine dcpa endothall fomesafen propyzamide ethofumesate permethrin dimethipin and fenarimol proposed tolerance actions by means of this rule the agency proposes the following changes to existing federal regulations currently tolerances for residues of 2 4-d in or on plant raw agricultural commodities fish and potable water are currently expressed in terms of 2 4-d 2 4-dichlorophenoxyacetic acid . the residues are regulated depending on the use pattern the form of the 2 4-d formulation applied e.g. acid salts timing of treatment preharvest or postharvest and some commodities are covered by two or more tolerances e.g. citrus . epa is proposing to subsume the lower tolerances in the higher existing tolerances delete use-pattern related language e.g. timing and formulation and revise current tolerances for residues of the herbicide plant regulator and fungicide 2 4-d 2 4- dichlorophenoxyacetic acid both free and conjugated determined as the acid. epa is proposing to increase and revise tolerances for the combined 2 4-d residues of concern in or on barley grain from 0.5 to 2.0 ppm millet grain from 0.5 to 2.0 ppm oat grain from 0.5 to 2.0 ppm rye grain from 0.5 to 2.0 ppm wheat grain from 0.5 to 2.0 ppm millet straw from 20 to 25 ppm millet forage from 20 to 25 ppm oat forage from 20 to 25 ppm rye forage 20 to 25 ppm wheat forage from 20 to 25 ppm rice grain from 0.1 to 0.5 ppm corn stover from 20 to 50 ppm ho from 0.05 to 0.2 ppm potato from 0.2 to 0.4 ppm and strawberry from 0.05 to 0.1 ppm and revise corn stover to corn field stover corn pop stover and corn sweet stover and revise ho to hop dried cones. 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 is proposing to decrease and revise tolerances for the combined 2 4-d residues of concern in or on corn forage from 20 to corn field forage and corn sweet forage at 6.0 corn fresh sweet kernel plus cob with husks removed at 0.5 to corn sweet kernel plus cob with husks removed at 0.05 ppm corn grain at 0.5 to corn field grain at 0.05 ppm and corn pop grain at 0.05 ppm fish 1.0 to 0.10 ppm fruit citrus at 5 ppm to fruit citrus grou 10 at 3.0 ppm fruit pome at 0.1 and apple pear and quince at 5 ppm to fruit pome grou 11 at 0.1 ppm apricot at 5 ppm and fruit stone at 0.2 ppm to fruit stone grou 12 at 0.1 ppm pistachio at 0.05 ppm grape from 0.5 to 0.1 ppm grass pasture and grass rangeland from 1 000 ppm to grass forage at 360 ppm rice straw from 20 to 10 ppm sorghum forage from 20 to sorghum grain forage at 0.2 ppm sorghum grain from 0.5 to sorghum grain grain at 0.2 ppm sorghum grain stover from 20 to 0.2 ppm sugarcane cane from 2 ppm to 0.05 ppm and sugarcane molasses from 5 to 0.2 ppm. epa proposes revising the tolerances for the combined 2 4-d residues of concern in or on blueberry at 0.1 ppm cranberry at 0.5 ppm raspberry at 0.1 ppm and small fruit at 0.1 n to berry grou 14 at 0.2 ppm. 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 is proposing to establish the tolerances for the combined 2 4-d residues of concern in or on almond hulls at 0.1 ppm barley bran at 4.0 ppm barley straw at 50 ppm grain aspirated fractions at 40 ppm oat straw at 50 ppm rice hulls at 2.0 ppm rye bran at 4.0 ppm rye straw at 50 ppm soybean hay at 2.0 ppm soybean forage at 0.02 ppm soybean seed at 0.02 ppm wheat bran at 4.0 ppm and wheat straw at 50 ppm.
