This regulation establishes an exemption from the requirement of a tolerance for residues of the biochemical, rhamnolipid biosurfactant, on all food commodities when applied/used as a fungicide. Jeneil Biosurfactant 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 rhamnolipid biosurfactant.
