**PESTICIDE PETITIONS PUBLISHED IN THE FEDERAL REGISTER EPA Registration Division contact:**  **[ Mark Dow (703) 305**  **- 5533**  **] Stepan Company**  **[I N**  **- 10837**  **]** EPA has received a pesticide petition **( IN**  **- 10837**  **)** from **Stepan Company ,**  **22 West Frontage Road, Northfield Illinois 60093**  proposing, pursuant to section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(d), to amend 40 CFR part 180. 2. to amend an exemption from the requirement of a tolerance for Alpha - [2,4,6- Tris[1 - (phenyl)ethyl]

phenyl] - Omega - hydroxy poly(oxyethylene) poly(oxypropylene) copolymer, the poly(oxypropylene) content averages 2 - 8 moles, the poly(oxyethylene) content averages 16- 30moles, average molecular weight (in am u) , 1,500 (CAS# 70880 - 56- 7) , when used as a pesticide inert ingredient as a surfactant in pesticide formulations under 40 CFR 180.960 in or on all raw agricultural commodities. The petitioner requests the poly(ox yethyl ene) content range is increased to inc lude 16 - 60 moles and the average molecular weight be established as a range to include 1,500 - 4,000 amu. The petitioner believes no anal ytical method is needed because this information is generally not required when all criteria for pol ymer exemption under 40 CFR 723.250 are met. In addition, Stepan Company

is petitioning for an exemption from the requirement of a tolerance without any

numerical limitations. Alpha - [2,4,6- Tris[1 - (phenyl)ethyl] phenyl ] - Omega - hydroxy poly(oxyethylene) poly(oxypropylene) copolymer, the poly(oxypropylene) content averages 2 - 8 moles, the poly(oxyethylene) content averages 16 - 60 moles, average molecular weight (in amu), 1,500- 4000 (CAS# 70880 - 56- 7 ) (substance) meets the definition of a low - risk poly mer under 40 CFR 723.250: 1. Substance is a p oly

mer molecule as defined by 40 CFR 723.250(b). That is, it contains a sequence of at least 3 monomer units which are covalentl y bound to at least one other monomer unit or other reactant. 2. Substance’s number average molecular weight is greater than 1 ,000 and less than 10,000 daltons. Substance contains less than 10% oligomeric material below MW 500 and less than 25% oligomeric material below MW 1,000 and substance does not contain any reactive functional groups. 3. Substance is not a cationic poly mer and is not anticipated to become a cationic poly mer in a natural aquatic environment. 4. Substance only

contains the elements carbon, hydrogen, and oxygen; therefore, it meets the criteria for elemental composition. 5. Substance does not contain as an integral part of its composition, except as impurities, any

element other than those listed in 40 CFR 723.250(d)(2)(ii). 6. Substance is not designed or reasonabl y anticipated to substantially degrade,2

decompose, or depoly

merize under normal use condition s. 7. Substance is not manufactured or imported from monomers and/or other reactants that are not already included on the TSCA Chemical Substance Inventory or manufactured under an applicable TSCA section 5 exemption. 8 . Substance is not a water- absorbin g pol ym er with a number average molecular weight above 10,000 daltons. 9. Substance contains no reactive functional groups that fail to meet the low - risk poly mer exemption criteria under 40 CFR 723.250(e). A. Residue Chemistry - **Not Applicable** 1.
