Pesticide Tolerances; Implementing Registration Review Decisions for Certain Pesticides. Proposed Rule

EPA is proposing several tolerance actions that the Agency previously determined were necessary or appropriate during registration review for the following pesticide active ingredients: chlorsulfuron, primisulfuron-methyl, triasulfuron, halosulfuron-methyl, sulfosulfuron, iodosulfuron-methyl-sodium, trifloxysulfuron-sodium, and mesosulfuron-methyl. The proposed tolerance actions for each pesticide active ingredient may include but are not limited to the following types of actions: revising tolerance expressions; modifying commodity definitions; updating crop groups; removing expired tolerances; revoking tolerances that are no longer needed; and harmonizing tolerances with Codex Maximum Residue Levels (MRLs).
