This regulation establishes an exemption from the requirement of a tolerance for residues of the Choline Chloride (Acetyl Choline) in or on all food commodities when applied/used pre-harvest and used in accordance with label directions and good agricultural practices. CP Bio, Inc., 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 Choline Chloride.
