This regulation establishes an exemption from the requirement of a tolerance for residues of the microbial active ingredient Beauveria bassiana HF23 (B. bassiana HF23) on all food and feed commodities when applied/used to treat chicken manure which will eventually be processed and used as fertilizer on agricultural crops. Jabb of the Carolinas 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 B. bassiana HF23.
