This regulation establishes an exemption from the requirement of a tolerance for residues of 2-Propenoic acid, polymer with [alpha]- [4-(ethenyloxy) butyl]-[omega]-hydroxypoly (oxy-1,2-ethanediyl), sodium salt; (CAS Reg. No. 250591-84-5); when used as an inert ingredient in a pesticide chemical formulation. BASF Corporation 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 2-Propenoic acid, polymer with [alpha]-[4-(ethenyloxy) butyl]-[omega]-hydroxypoly (oxy-1,2-ethanediyl), sodium salt on food or feed commodities.
