This regulation establishes an amendment to the exemptions from the requirement of a tolerance for residues of dimethyl silicone polymer with silica; silane, dichloromethyl-, reaction product with silica; and hexamethyldisilizane, reaction product with silica; when used as inert ingredients on growing crops, when applied to raw agricultural commodities after harvest, or to animals. Cabot Corporation submitted a petition 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.
