## Abstract

This regulation establishes an exemption from the requirement of a tolerance for residues of N,N,N',N",-tetrakis-(2-hydroxypropyl) ethylenediamine (NTHE) when used as an inert ingredient for pre-harvest uses under 40 CFR 180.920 at a maximum of 20% by weight in pesticide formulations. The Joint Inerts Task Force (JITF), Cluster Support Team Number 15 (CST 15), submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of NTHE.
