## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of diethylene glycol mono butyl ether (CAS Reg. No. 112-34-5) when used as a pesticide inert ingredient as a solvent, stabilizer and/or antifreeze within pesticide formulations/ products without limitation under 40 CFR 180.920. Huntsman, Dow AgroSciences L.L.C., Nufarm Americas Inc., BASF, Stepan Company, Loveland Products Inc., and Rhodia Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of diethylene glycol mono butyl ether.
