This regulation establishes an exemption from the requirement of a tolerance for residues of sodium alkyl naphthalenesulfonate, herein referred to in this document as SANS, when used as an inert ingredient at a maximum of 30% by weight in pesticide formulations for pre-harvest and post-harvest uses, as well as, for application to animals. The Joint Inerts Task Force (JITF), Cluster Support Team Number 10, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of SANS.
