## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of styrene-ethylene-propylene block copolymer (CAS Reg. No. 108388-87-0) when used as an inert ingredient in a pesticide formulation. AgroFresh 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 styrene-ethylene-propylene block copolymer on food or feed commodities.
