## Abstract

This regulation establishes an exemption from the requirement of a tolerance under 40 CFR 180.920 for residues of 1,2-ethanediamine, N,N,N ',N '-tetramethyl-, polymer with 1,1'-oxybis[2-chloroethane] (CAS Reg. No. 31075-24-8) when used as an inert ingredient in pesticide formulations applied to cotton or wheat crops only. Buckman Laboratories International, Inc 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 1,2- ethanediamine, N,N,N ',N '-tetramethyl-, polymer with 1,1'-oxybis[2- chloroethane].
