## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of poly(oxy-1,2-ethanediyl), [alpha]- isotridecyl-[omega]-methoxy (CAS Reg. No. 345642-79-7) when used as an inert ingredient (surfactant) at a maximum concentration of 10% in pesticide formulations under 40 CFR 180.920 on growing crops only. Bayer CropScience submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of poly(oxy-1,2-ethanediyl), [alpha]-isotridecyl-[omega]- methoxy.
