## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of ethylene oxide adducts of 2,4,7,9- tetramethyl-5-decynediol, the ethylene oxide content averages 3.5, 10, or 30 moles, herein referred to in this document as ethoxylated acetylenic diols, when used as inert ingredients in pesticide formulations for pre-harvest and post-harvest uses under 40 CFR 180.910, as well as for application to animals under 40 CFR 180.930. The Joint Inerts Task Force (JITF), Cluster Support Team Number 19, 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 the ethoxylated acetylenic diols.
