This regulation establishes an exemption from the requirement of a tolerance for residues of the Pseudomonas chlororaphis Strain 63- 28 in or on all food commodities. Agrium US, Inc. 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 exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of Pseudomonas chlororaphis Strain 63-28.
