proposed rule. amitraz atrazine ethephon ferbam lindane propachlor and simazine proposed tolerance actions by means of this rule and on the basis of available data the agency proposes the following changes to existing federal regulations for the pesticide ethephon due to a lack of registered uses epa is proposing to revoke the tolerances for residues of ethephon in or on cranberry and fig and barley pearled barley. because active registrations with use for ethephon on pumpkins prohibit harvesting for human or animal consumption and limit use to seed production only the agency has determined that the tolerance on pumpkin is no longer needed. therefore epa is proposing to revoke the tolerance on pumpkin. epa is proposing that tolerances on the fat and meat of cattle goats hogs horses and shee be decreased from 0.1 to 0.02 ppm tolerances on meat byproducts of cattle goats horses and shee should be separated into meat byproducts except kidney and kidney and the tolerances on meat byproducts except kidney should be increased from 0.1 to 0.2 ppm and tolerances on kidney should be increased from 0.1 to 1.0 ppm and the tolerance on milk should be decreased from 0.1 to 0.01 ppm. in addition epa is proposing to decrease tolerances on cattle fat cattle meat goat fat goat meat hog fat hog meat horse fat horse meat sheep fat and sheep meat to 0.02 ppm. further epa is proposing to change some commodity terminology by revising the terminology cattle meat byproducts goat meat byproducts hog meat byproducts horse meat byproducts and sheep meat byproducts to read cattle meat byproducts except kidney cattle kidney goat meat byproducts except kidney goat kidney hog meat byproducts except kidney hog kidney horse meat byproducts except kidney horse kidney and sheep meat byproducts except kidney and sheep kidney respectively. epa is also proposing to increase tolerances on cattle meat byproducts except kidney2 goat meat byproducts except kidney hog meat byproducts except kidney horse meat byproducts except kidney and sheep meat byproducts except kidney to 0.2 ppm and to increase tolerances on cattle kidney goat kidney hog kidney horse kidney and sheep kidney to 1.0 ppm and decrease the tolerance on milk to 0.01 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. the agency is proposing to increase the tolerance on coffee bean green and on cotton undelinted seed to 0.5 ppm and 6.0 ppm respectively. the agency is proposing to establish a tolerance for residues of ethephon on apple juice at 10.0 ppm. the agency is proposing to establish a tolerance on cotton gin byproducts at 180.0 ppm. the agency is proposing to establish a tolerance on wheat germ at 5.0 ppm. epa is proposing to establish tolerances on egg at 0.002 ppm poultry fat at 0.02 ppm poultry meat at 0.01 ppm poultry meat byproducts except liver at 0.01 ppm and poultry liver at 0.05 ppm.
