## Abstract

This regulation amends an exemption from the requirement of a tolerance for residues of [alpha]-alkyl-[omega]- hydroxypoly(oxypropylene) and/or poly (oxyethylene) polymers where the alkyl chain contains a minimum of six carbons, and a minimum number average molecular weight (in amu) 1,100 (herein referred to as "AAAs" (alkyl alcohol alkoxylates)) to include Poly(oxy-1,2-ethanediyl), [alpha]-isooctyl-[omega]-hydroxy (CAS Reg. No. 61723-78-2) when used as an inert ingredient (surfactant, related adjuvants of surfactants) in pesticide formulations. The Spring Trading Company on behalf of Sasol Chemicals (USA) submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an amendment to an existing 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]-isooctyl-[omega]-hydroxy.
