## Abstract

This regulation establishes tolerances for combined residues of quizalofop-p ethyl ester [ethyl (R)-(2-[4-((6-chloroquinoxalin-2- yl)oxy)phenoxyl] propanoate), and its acid metabolite quizalofop-p [(R)-(2-[4-((6-chloroquinoxalin-2-yl)oxy)phenoxyl]propionate) and the S enantiomers of the ester and the acid, all expressed as quizalofop-p ethyl ester in or on canola seed, canola meal, peppermint tops and spearmint tops. DuPont Agricultural Products requested the tolerances for canola and the Interregional Research Project Number 4 (IR-4) requested the tolerances for peppermint and spearmint. These tolerances were requested under the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996 (Pub. L. 104-170).
