## Abstract

EPA is amending 40 CFR 180.560 to add a reference to the active ingredient pyroxsulam to the tolerance for the inert ingredient cloquintocet-mexyl (acetic acid [(5-chloro-8-quinolinyl) oxy]-, 1- methylhexyl ester; CAS Reg. No. 99607-70-2) and its acid metabolite (5- chloro-8-quinolinoxyacetic acid). EPA is also revising existing tolerance levels for cloquintocet-mexyl in or on wheat, forage and wheat, hay, and is removing the specification of a 1:4 ratio inert ingredient safener to active ingredient from the tolerance expression. Dow AgroSciences, LLC and Syngenta Crop Protection requested the tolerance amendments for the inert ingredient safener cloquintocet- mexyl under the Federal Food, Drug, and Cosmetic Act (FFDCA).
