This regulation amends the existing exemption from the requirement of a tolerance for residues of the biochemicals classified as lepidopteran pheromones, which are naturally occurring compounds, or identical or substantially similar synthetic compounds to include use as a "post-harvest treatment" on all stored food commodities. Bedoukian Research, 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 biochemicals classified as lepidopteran pheromones.
