## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of the polymers dimethyl silicone polymer with silica; silane, dichloromethyl-, reaction product with silica; and hexamethyldisilizane, reaction product with silica when used as inert ingredients in growing crops, when applied to raw agricultural commodities after harvest, or to animals. Cabot Corporation submitted petitions to EPA under the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996 requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of dimethyl silicone polymer with silica; silane, dichloromethyl-, reaction product with silica; and hexamethyldisilizane, reaction product with silica.
