## Abstract

This regulation amends an existing exemption from the requirement of a tolerance for residues of sodium thiosulfate on raw agricultural commodities when used in pesticide formulations as an inert ingredient on raw agricultural commodities after harvest. Eden Bioscience Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting an unlimited exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of sodium thiosulfate.
