This regulation establishes an exemption from the requirement of a tolerance for residues of salicylaldehyde (2-hydroxybenzaldehyde, CAS Reg. No. 90-02-8) when used as an inert ingredient (penetration aid) in pesticide formulations applied to growing crops and raw agricultural commodities under 40 CFR 180.910 at a concentration not to exceed 14% by weight of the pesticide formulation. Ag-Chem Consulting LLC, on behalf of Omex Agrifluids submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of salicylaldehyde.
