This regulation establishes an exemption from the requirement of a tolerance for residues of cis -3-hexen-1-ol also known as leaf alcohol or 3-hexen-1-ol, (3Z)- (CAS Reg. No. 928-96-1) when used as an inert ingredient - an odorant or alerting agent in certain pesticide formulations. Syngenta Crop Protection, 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 cis -3-hexen-1-ol.
