## Abstract

This regulation amends the exemption from the requirement of a tolerance for residues of tetrahydrofurfuryl alcohol (THFA) (CAS Reg. No. 97-99-4) when used as an inert ingredient in pesticide formulations to add one herbicide application prior to the preboot stage on buckwheat, oats, rye, sorghum, triticale, rice and wild rice; extend use on canola to the early bolting stage; extend use on soybeans prior to the bloom growth stage; and allow use in herbicides with two applications to field corn and popcorn prior to 36 inches tall (V8 stage). Toxcel, LLC, on behalf of Penn A Kem, LLC, 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 tetrahydrofurfuryl alcohol.
