## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of poly(oxy-1,2-ethanediyl), [alpha]-(3- carboxy-1-oxosulfopropyl)-[omega]-hydroxy-, alkyl (C<INF>10</INF>- C<INF>16</INF>) ethers, disodium salts with a polyoxyethylene (POE) content averaging 5-15 moles, specifically CAS Reg. Nos. 68815-56-5, 68954-91-6, 1013906-64-3, and 1024612-24-5, when used as inert ingredients (surfactants) in pesticide formulations applied to crops at a concentration not to exceed 10% by weight under 40 CFR 180.910. Keller and Heckman LLP on behalf of Cytec Industries, Inc., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting the establishment of exemptions from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of these poly(oxy-1,2-ethanediyl), [alpha]-(3-carboxy-1-oxosulfopropyl)-[omega]-hydroxy-, alkyl (C<INF>10</INF>-C<INF>16</INF>) ethers, disodium salts.
