This regulation establishes an exemption from the requirement of a tolerance for residues of poly(oxy-1,2-ethanediyl), [alpha]-hydro- [omega]-hydroxy-, polymer with 1, 1'-methylene-bis-[4- isocyanatocyclohexane]; when used as an inert ingredient in a pesticide chemical formulation under 40 CFR 180.960. UDL Laboratories, 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 poly(oxy-1,2-ethanediyl), [alpha]- hydro-[omega]-hydroxy-, polymer with 1, 1'-methylene-bis-[4- isocyanatocyclohexane] on food or feed commodities.
