This regulation establishes an exemption from the requirement of a tolerance for residues of poly[oxy(methyl-1,2-ethanediyl)], [alpha]-[(9Z)-1-oxo-9-octadecen-1-yl]-[omega]-[[(9Z)-1-oxo-9-octadecen- 1yl]oxy]- (CAS Reg. No. 26571-49-3) when used as an inert ingredient in a pesticide chemical formulation. BYK USA 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(methyl-1,2-ethanediyl)], [alpha]-[(9Z)-1-oxo-9- octadecen-1-yl]-[omega]-[[(9Z)-1-oxo-9-octadecen-1yl]oxy]- on food or feed commodities.
