## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of dimethyl ether or methane, oxybis- as an inert ingredient (propellant) in pesticide formulations applied to growing crops or to raw agricultural commodities (RAC) after harvest. The DuPont Company, DuPont Fluoroproducts submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of dimethyl ether.
