Tristyrylphenol Ethoxylates; Exemption From the Requirement of a Tolerance

This regulation establishes an exemption from the requirement of a tolerance for residues of poly (oxy-1,2-ethanediyl), [alpha]- [tris(1-phenylethyl)phenyl]-[omega]-hydroxy-, (CAS Reg. No. 99734-09- 5), here in referred to as tristyrylphenol ethoxylate, when used as an inert ingredient post-harvest as a surfactant under 40 CFR 180.910 with a maximum of 15 percent by weight in pesticide formulations. Ag-Chem Consulting, on behalf of LG Life Science, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting the establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of tristyrylphenol ethoxylate.
