## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of N-(n-octyl)-2-pyrrolidone (CAS Reg. No. 2687-94-7) when used as an inert ingredient (solvent) in formulations of pyraflufen-ethyl herbicide at a maximum concentration of 20% weight. Wagner Regulatory Associates on behalf of Nichino America, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of N-(n-octyl)-2- pyrrolidone.
