## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of 1-propanesulfonic acid, 2-methyl-2-[(1- oxo-2-propenyl)amino]-, monosodium salt, polymer with ethenol and ethenyl acetate (CAS Reg. No. 107568-12-7) when used as an inert ingredient in a pesticide chemical formulation. Keller and Heckman, LLP submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA) requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of 1-propanesulfonic acid, 2-methyl-2-[(1-oxo-2- propenyl)amino]-, monosodium salt, polymer with ethenol and ethenyl acetate.
