This regulation establishes an exemption from the requirement of a tolerance for residues of propylene glycol monomethyl ether (PGME; CAS No. 107-98-2) when used as an inert ingredient under 40 CFR 180.910 as a solvent in pesticide formulations which include pre-and post- harvest use on crops. Syngenta Crop Protection 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 PGME.
