## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of FD&C Blue No. 1 (CAS Reg. No. 3844-45-9) when used as an inert ingredient (dye) in pesticides formulation applied to growing crops (seed treatment). Exponent on behalf of Sensient Colors, LLC 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 FD&C Blue No. 1.
