**EPA REGISTRATION DIVISION COMPANY NOTICE OF FILING FOR PESTICIDE PETITIONS PUBLISHED IN THE FEDERAL REGISTER**  **EPA Registration Division contact: Kerry Leifer 703**  **- 308**  **- 8811**  **TEMPLATE: Trinseo LLC**  **[ IN**  **- 10907**  **]** EPA has received a pesticide petition ( IN

- 10907 ) from Trinseo LLC , c/o Keller and Heckman LLP, 1001 G Street, NW, Suite 500 West, Washington, DC 20001 requesting, 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 to establish an exemption from the requirement of a tolerance for **butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate with an average molecular weight of greater than 10,000 daltons (CAS**  **Reg. No. 36089 -**  **06 -**  **2) under 40 CFR §**  **180.960 in or on raw agricultural commodities**  **when used as a pesticide inert ingredient in pesticide formulations without limitation. EPA has determined that the petition contains data or information regarding the element**  **s set forth in section 408 (d)(2) of FDDCA; however, EPA has not fully evaluated the sufficiency**  **of the submitted data at this time or whether the data supports granting of the petition.**  **Additional data may be needed before EPA rules on the petition.** A. Residue Chemistry **1.** Plant metabolism. **NA -**  **Remove. No specific plant metabolism data is available, nor is it required for the establishment of a tolerance exemption.**  **2. Analytical method.**  **NA -** **Remove. An analytical method is not required for enforcement p**  **urposes since the Agency is establishing an exemption from the requirement of**  **a tolerance without any numerical limitation. 3.**  **Magnitude of residues. NA** **- Remove. Information regarding the nature and**  **magnitude of chemical residues resulting from the use o f**  **this inert ingredient is not required for the establishment of a tolerance exemption.**  **B. Toxicological Profile** 1. **Butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate is a polymer as defined by 40 CFR 723.250(b).**  2. **Butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate will not become cationic in an aquatic environment.** 3. **Butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydr oxyethyl 2**  **- propenoate is composed of hydrogen, oxygen, and carbon: therefore, it**  **meets the criteria of elemental composition.**2

4. **Butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate 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).** 5. **Butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate is not designed nor reasonab ly expected to degrade,**  **decompose, or depolymerize under normal conditions of manufacture, use and disposal.** 6. **Butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate is composed of molecules that are liste d on the TSCA**  **Inventory or manufactured under an applicable TSCA section 5 exemption.** 7. **Butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate is not a water absorbing polymer and cannot absorb its own weig**  **ht in water.** 8. **Butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate does not contain any perfluoroalkyl moieties consisting of a CF**  **3 -**  **or longer chain length as specified in 40 CFR 723.250(d)(6).** 9. **Butanedi oic acid, 2**  **- methylene** **- , polymer with 1,3**  **- butadiene, ethenylbenzene and 2**  **- hydroxyethyl 2**  **- propenoate consists of a number average molecular weight of greater**  **than 10,000 daltons. 1.**  **Acute toxicity. NA** **- Remove**  **2. Genotoxicty.**  **NA -**  **Remove 3.**  **Reproductive a nd developmental toxicity.**  **NA -**  **Remove 4.**  **Subchronic toxicity. NA** **- Remove**  **5. Chronic toxicity.**  **NA -**  **Remove 6.**  **Animal metabolism. NA** **- Remove**  **7. Metabolite toxicology**  **. NA** **- Remove**  **8. Endocrine disruption**  **. NA** **- Remove**  **C. Aggregate Exposure 1.**  **Dietary expos ure.**  **The physical -**  **chemical characteristics of butanedioic acid, 2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene and 2 -**  **hydroxyethyl 2 -**  **propenoate leads to the conclusion that there is a reasonably certainty of no harm from exposure to the**  **polymer fr om food or drinking water nor from an aggregate exposure.**  **i. Food.**  **NA -**  **Remove ii.**  **Drinking water. NA** **- Remove**  **2. Non**  **- dietary exposure**  **. The physical** **- chemical characteristics of butanedioic acid,**  **2 -**  **methylene -**  **, polymer with 1,3 -**  **butadiene, ethenylbenzene a nd 2**  **- hydroxyethyl 2**  **- propenoate lead to the conclusion that there is a reasonable certainty of no harm from**  **exposure to the polymer from non -**  **dietary means.**3

**D. Cumulative Effects At this time there is no information to indicate that any toxic effects pro**  **duced by butanedioic acid, 2**  **- methylene** **- , polymer with 1,3**  **- butadiene, ethenylbenzene and 2**  **- hydroxyethyl 2**  **- propenoate would by cumulative with any other chemical. Given the**  **compound’s categorization as a low risk polymer, and its proposed use in pesticide fo**  **rmulations, there is no expectation of increased risk due to cumulative exposure. E. Safety Determination**  **1. U.S. population.**  **Based on the polymer’s physical -**  **chemical properties, and that it meets or exceeds the polymer exemption criteria at 40 CFR 723.**  **250 for low -**  **risk polymers, adverse effects are not expected.**  **2. Infants and children**  **. Based on the polymer’s physical**  **- chemical properties, and**  **that it meets or exceeds the polymer exemption criteria at 40 CFR 723.250 for low -**  **risk polymers, adverse effect**  **s are not expected. F. International Tolerances**  **The Codex Alimentarius Commission (Codex) has not established a MRL for butanedioic acid, 2**  **- methylene** **- , polymer with 1,3**  **- butadiene, ethenylbenzene and 2**  **- hydroxyethyl 2**  **- propenoate and there are no maximum re**  **sidue limits established for butanedioic acid, 2**  **- methylene** **- , polymer with 1,3**  **- butadiene, ethenylbenzene and 2**  **- hydroxyethyl 2**  **- propenoate in or on crops or commodities of which the petitioner is aware.**
