This regulation establishes an exemption from the requirement of a tolerance for residues of the Bacillus cereus strain BPO1 on raw and processed food when applied/used as a foliar applied biological plant growth regulator intended to promote root mass growth, earlier fruit initiation, increased fruit retention, and increased nutrient utilization. Micro Flow Company 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 Bacillus cereus strain BPO1.
