This regulation amends the existing tolerance exemption for residues of Complex Polymeric Polyhydroxy Acids (CPPA) in or on all food commodities as a plant growth regulator to add use as a nematicide in pesticide formulations. FBSciences, Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA) requesting this amendment. This regulation adds use as a nematicide to the existing tolerance exemption of CPPA under FFDCA.
