This regulation establishes an exemption from the requirement of a tolerance for residues of titanium dioxide (CAS Reg. No. 13463-67- 7) when used as an inert ingredient (Ultraviolet-stabilizer) (UV), at no more than 5% in pesticide formulations containing the active ingredient napropamide, used in or on growing crops. United Phosphorus, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an amendment to an existing requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of titanium dioxide.
