This regulation establishes an exemption from the requirement of a tolerance for residues of nicotinamide (CAS Reg. No. 98-92-0) when used as an inert ingredient (corrosion inhibitor) on growing crops only and limited to 5.0% in a pesticide formulation. Dow AgroSciences LLC 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 nicotinamide.
