This regulation establishes an exemption from the requirement of a tolerance for residues of the (Z)-7,8-epoxy-2-methyloctadecane on all food and feed crops when used to treat trees, shrubs, and pastures resulting in unintentional spray and drift from application as well as unintentional spray and drift to non-target vegetation including non-food, food, and feed crops. Aberdeen Road Company d/b/a Hercon Environmental 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 (Z)-7,8-epoxy-2-methyloctadecane. This active ingredient (AI) is also known as Disparlure.
