## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of 1-propanesulfonic acid, 2-methyl-2-[(1- oxo-2-propen-1-y1)amino]-, homopolymer, sodium salt (CAS Reg. No. 55141-01-0), and 1-propanesulfonic acid, 2-methyl-2-[(1-oxo-2-propen-1- y1)amino]-, sodium salt (1:1), homopolymer (CAS Reg. No. 35641-59-9); when used as inert ingredients in a pesticide chemical formulation. BASF Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), 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-propen-1-y1)amino]-, homopolymer, sodium salt) and 1-propanesulfonic acid, 2-methyl-2[(1oxo-2propen-1-y1)amino]- , sodium salt (1:1), homopolymer on food or feed commodities.
