## Abstract

This regulation amends an exemption from the requirement of a tolerance for residues of [alpha]-([rho]-Nonylphenyl)poly(oxypropylene) block polymer with poly(oxyethylene); when used as an inert ingredient in a pesticide chemical formulation. Stephan Company 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 [alpha]- ([rho]-Nonylphenyl)poly(oxypropylene) block polymer with poly(oxyethylene) on food or feed commodities.
