EPA is revoking specific tolerances, in follow-up to canceled uses or where a commodity is no longer a significant feed item, for butylate, clethodim, dichlorvos, dicofol, isopropyl carbanilate, methanearsonic acid, methomyl, naled, primisulfuron-methyl, tralomethrin, and ziram, and the tolerance exemption for pine oil. However, EPA will not revoke the dicofol tolerances on tea and tolerance exemptions for rotenone, derris, or cube roots at this time. Also, EPA is making minor revisions to the tolerance expressions for dicofol, methanearsonic acid, methomyl, and tralomethrin, revising the nomenclature of specific tolerances for butylate, methomyl, and tralomethrin, and removing expired tolerances for certain pesticide active ingredients, in accordance with current EPA practice. In addition, EPA is reinstating popcorn tolerances for metolachlor to remedy an inadvertent omission and cover existing registrations.
