## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of tris (2-ethylhexyl) phosphate (TEHP, CAS Reg. No. 78-42-2) when used as an inert ingredient in pesticide formulations with the active ingredients pinoxaden, clodinafop- propargyl, and tralkoxydium, with no more than two applications per season when applied to wheat and barley up to the pre-boot stage (prior to formation of edible grain). Syngenta Crop Protection, LLC 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 TEHP.
