proposed rule. chloroneb cypermethrin methidathion nitrapyrin oxyfluorfen pirimiphos-methyl sulfosate tebuthiuron thiabendazole thidiazuron and tribuphos proposed tolerance actions by this rule epa proposes to change regulations concerning thiabendazole as follows currently thiabendazole tolerances are established and expressed for residues of the fungicide thiabendazole 2- 4thiazolyl benzimidazole in or on plant commodities. however epa has determined that for the purpose of tolerance regulation that its metabolite benzimidazole free and conjugated should be included as a residue of concern in or on plant commodities. therefore epa is proposing to revise the tolerance expression as follows due to redundancy in pre-existing regulation epa is proposing to revoke the tolerance for thiabendazole residues of concern in or on banana pulp postharvest. due to lack of use epa is proposing to revoke the tolerances for thiabendazole residues of concern in or on squash hubbard rice hulls rice rough and rice straw. due to relevant risk assessment epa is proposing to revoke tolerances for thiabendazole on potato processing waste pre- post-h and wheat milled fractions except flour citrus dried pulp postharvest poultry poultry meat byproducts poultry meat and egg cattle fat goat fat hog fat horse fat and sheep fat goat meat hog meat horse meat and sheep meat. based on relevant data epa is proposing to decrease the tolerance in 40 cfr 180.242 a 2 on milk to 0.1 ppm on apple postharvest and pear postharvest and combine them into a grou tolerance for fruit pome grou 11 postharvest at 5.0 ppm and to increase tolerances for thiabendazole on cattle meat byproducts goat meat byproducts horse meat byproducts on hog meat byproducts to 0.3 ppm and sheep meat byproducts to 0.4 ppm on sweet potato post-h to sweet potato intended only for use as seed to 0.05 ppm. the agency determined that the increased tolerance is 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 a tolerance on apple wet pomace at 12.0 ppm. further the agency determined that a tolerance on citrus oil should be established at 15.0 ppm. in addition epa is proposing to revise commodity terminology to conform to current agency practice as follows fruit citrus postharvest to fruit citrus grou 10 postharvest. currently there is an active registration for thiabendazole use on sugar beets. the registrant does not intend to support the sugar beet tolerances. consequently epa will not take action to revoke the sugar beet tolerances at this time but will follow-u with the registrant on amending the registration in order to delete the sugar beet use and address the tolerances in a future publication in the federal register.
