proposed rule benfluralin carbaryl diazinon dicrotophos fluometuron formetanate hydrochloride glyphosate metolachlor napropamide norflurazon pyrazon and tau-fluvalinate proposed tolerance actions this notification announces a proposed rule that existing epa tolerances for residues of glyphosate hydrochloride in or on the following commodity ies be established at or changed to the following values in parts per million ppm or be eliminated as indicated below the agency proposed changes in tolerances for glyphosate in the federal register notice published on 7 june 2006 71 fr 32899 frl-8062-7 which include harmonization with some codex tolerances. the agency received public comment from monsanto company generally agreeing with the proposed tolerance changes for glyphosate. however monsanto alerted the agency of more recent changes to glyphosate mrls finalized by the codex alimentarius commission in july of 2006. monsanto provided a detailed list of suggested changes to the us tolerances established on glyphosate to achieve better alignment with the newly established codex mrls. in response to this comment the agency agreed to consider monsantos recommendations for harmonization with codex in a future proposal. the agency has now determined that the following commodities can be harmonized with codex mrls cereal grain cro grou 15 cotton seed corn maize rapeseed canola seed and liver and kidney commodities of cattle goats hogs horses and sheep. the current tolerance for residues of glyphosate in or on grain cereal grou 15 is 0.1 parts per million ppm but excludes the major cro grains barley field corn grain sorghum oat and wheat and covers the minor cro grains buckwheat millet popcorn rice rye sweet corn teosinte triticale and wild rice. individual tolerances currently exist for barley grain 20 ppm corn field grain 1.0 ppm sorghum grain grain 15 ppm oat grain 20 ppm and wheat grain 5.0 ppm . epa proposes to amend tolerances for glyphosate in on grain cereal grou 15 except barley field corn sorghum oat and wheat to grain cereal grou 15 except field corn popcorn rice sweet corn and rice wild and increase the tolerance to 30 ppm and to revoke the individual tolerances for barley grain at 20 ppm oat grain at 20 ppm sorghum grain grain at 15 ppm wheat grain at 5 ppm wheat middlings at 20 ppm wheat shorts at 20 ppm and wheat bran at 20 ppm and establish individual tolerances for corn sweet grain at 0.1 ppm corn pop grain at 0.1 ppm rice grain at 0.1 ppm rice wild at 0.1 ppm and increase the tolerance for corn field grain from 1 ppm to 5 ppm. epa proposes increasing the tolerances for the glyphosate residues of concern in on cotton undelinted seed from 35 ppm to 40 ppm rapeseed seed from 10 ppm to 20 ppm canola seed from 10 ppm to 20 ppm and revoking rapeseed meal at 15 ppm and canola meal at 15 ppm. epa proposes revoking tolerances residues of glyphosate in or on cattle kidney at 4.0 ppm cattle liver at 0.5 ppm goat kidney at 4.0 ppm goat liver at 0.5 ppm horse kidney at 4.0 ppm horse liver at 0.5 ppm sheep kidney at 4.0 ppm sheep liver at 0.5 ppm hog kidney at 4.0 ppm and hog liver at 0.5 ppm and establish tolerances for cattle meat byproducts at 5 ppm goat meat byproducts at 5 ppm horse meat byproducts at 5 ppm sheep meat byproducts at 5 ppm and hog meat byproducts at 5 ppm. epa proposes to correct errors by revoking the incorrect tolerances for sunflower seed at 0.1 ppm safflower seed at 0.1 ppm and vegetable legume grou 6 except soybean at 5.0 ppm and correcting the terminology for sunflower to sunflower seed at 85 ppm and safflower to safflower seed at 85 ppm.
