## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of starch, oxidized, polymers with Bu acrylate, tert-Bu acrylate and styrene, minimum number average molecular weight (in amu) 10,000, (CAS Reg. No. 204142-80-3) when used as an inert ingredient in a pesticide chemical formulation under 40 CFR 180.960. Kemira Chemicals, Inc., 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 starch, oxidized, polymers with Bu acrylate, tert-Bu acrylate and styrene, on food or feed commodities.
