This regulation amends the exemption from the requirement of a tolerance for residues of titanium dioxide (CAS Reg. No. 13463-67-7) when used as an inert ingredient in pesticide formulations applied to growing crops to allow for use as a carrier. SciReg. Inc., on behalf of Bayer CropScience Biologics GmbH, 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 titanium dioxide resulting from this use.
