## Abstract

This regulation revises the exemption from the requirement of a tolerance for residues of butene, homopolymer when used as an inert ingredient in a pesticide chemical formulation. Miller Chemical and Fertilizer Corporatation 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 a revision of an exemption (which has already been established) from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of butene, homopolymer.
