## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of potassium carbonate in or on all food commodities when used as a biochemical fungicide in accordance with label directions and good agricultural practices. Biofungitek, S.L. submitted a petition, pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance for the biochemical pesticide potassium carbonate. This regulation eliminates the need to establish a maximum permissible level for residues of potassium carbonate under FFDCA when used in accordance with this exemption.
