## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid, butyl ester, polymer with ethyl 2-propenoate and N-(hydroxymethyl)-2-propenamide (CAS Reg. No. 33438-19-6) when used as an inert ingredient in a pesticide chemical formulation. Rohm and Haas Chemicals LLC, 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 2-propenoic acid, butyl ester, polymer with ethyl 2- propenoate and N-(hydroxymethyl)-2-propenamide on food or feed commodities.
