October 15 , 2015 EPA Registration Division contact: Tony Kish (703) 308 - 9443 5F8414 Valent USA Corporation Summary of Petition EPA has received a pesticide petition (Insert Petition Number) from Valent U.S.A. Corporation, 1600 Riviera Avenue, Suite 200, Walnut Creek, CA 94596, 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 180.627, b y revising a tolerance for residues of the fungicide chemical fluopicolide, 2,6 - dichloro -N - [3 - chloro - 5 - (trifluoromethyl ) - 2 - pyridylmethyl] - benzamide , as an indicator of combined residues of fluopicolide and its metabolite 2,6 - dichlorobenzamide (BAM), in or on the raw agricultural commodity vegetables, tuberous and corm (subgroup 1C) to 0. 1 0 ppm and potato processed waste to 0.25 ppm, potato flakes at 0.15ppm, and potato chips 0.1ppm resulting from the proposed use as a fungicide. EPA has determined that the petition contains data or information regarding the elements set forth in section 408(d)(2) of the FFDCA; however, EPA has not fully

evaluated the sufficiency of the submitted data at this time or whether the data supports granting of the petition. Addition al data may be needed before EPA rules on the petition. A. Residue Chemistry 1. Plant metabolism . The metabolism of fluopicolide in crop plants has been reported previously

and is adequately

understood for the purpose of granting the proposed tolerances. 2. Analytical method. Practical anal ytical methods for detecting and measuring levels of fluopicolide and its metabolites have been developed, validated, and submitted for all appropriate plant and animal matrices.Page **2** of **4**

3. Magnitude of residues . Sufficient technical information which adequately supports the proposed tolerances in crop group1 C have been submitted to the Agency . B. Toxicological Profile The toxicological profile and toxicological endpoints for fluopicolide and BAM supporting this petition for tolerances was published in the Federal Register on January 3 0, 2008 (Volume 73, Number 20) and May 2 8, 2008 (Volume 73 Number 103) and April 20, 2011 (Volume 76, Number 76). An immunotoxicity s tudy h as been submitted to the Agency and is currentl y in review. . The toxicology database for fluopicolide is complete. C. Aggregate Exposure Valent USA Corporation has conducted an evaluation to estimate the potential chronic dietary exposure of the U.S. population and various subgroups to the revised residues of fluopicolide in potatoes. Because fluopicolide is not acutel y toxic and not carcinogenic, no acute or cancer exposure assessment was performed. Dietary Exposure Evaluation Model - Food Commodity Intake Database (DEEM - FCID) version 2.16 was used to conduct a fluopicolide dietary assessment using highly

conservative, tolerance based assumptions at 1.0 ppm. 1. Dietary exposure. i. Food. Dietary

exposure (food) assessments were conducted to evaluate the potential risk due to chronic dietary exposure of the U.S. population and various subgroups to tolerance level residues of fluopic olide and/or its metabolites from currently registered crops and from the incremental increase from the proposed revised potato tolerance. Default processing factors and 100% crop treated were assumed. ii. Drinking water. Since fluopicolide application rates do not change from the previous assessment conducted b y the Agency (U.S. Environmental Protection Agency (EPA). 2010. “Fluopicolide and its Metabolite, 2,6 - Dichlorobenzamide (BAM).

Assessment to Support New Section 3 Use s on Brassica Le af y Greens Subgroup 5B, Potatoes, Sugar Beets, Carrots and to Allow Rotation to Wheat. PC Codes 027412 (fluopicolide), 027402 (BAM), 027401 (dichlobenil). DP Barcode 384431. D.Davis (HED). Office of Pesticide Programs, Washington, DC. November 30), no new assessment was conducted. 2. Non - dietary exposure . The proposed revised tolerance will not result in any additional non - dietary

exposure. 3. Aggregate Exposure Assessment. The risk assessment includes residues from previously

approved crop tolerances and the revised potato tolerances at 1.0 ppm. An acute risk assessment was not conducted because there was no acute toxicology endpoint identified. For the chronic risk assessment scenarios, the endpoint utilized was 20 mg/kg/day based on the rabbit developmental toxicity study . No additional FQPA factor was used (1X). For the dietary

(food) chronic 99.9 th percentile exposure pathway at 1.0 ppm fluopicolide equivalents, children ages 1 - 2 were the highest exposed group with an estimated exposure of 14 % of the cPAD.Page **4** of **4**

Drinking water would remain unchanged. Based on this incremental risk assessment, the exp osure for all routes and all population subgroups do not exceed EPA’s level of concern (<100%cPAD). D. Cumulative Effects Section 408(b)(2)(D)(v) requires that, when considering whether to establish, modify , or revoke a tolerance, the Agency c onsider “available information” concerning the cumulative effects of a particular pesticide’s residues and “other substances that have a common mechanism of toxicity”. E PA does not have, at this time, available data to determine whether fluopicolide has a common me chanism of toxicity w ith other substances or how to include this pesticide in a cumulative risk assessment. For the purposes of this tolerance action, EPA has not assumed that fluopicolide has a common mechanism of toxicity with other substances. E. Safe ty Determination 1. U.S. population . Valent USA concludes that there is a reasonable certainty that no harm will result to the U.S. population (or any s ub - populations) by

including the incremental additional exposure resulting from the proposed uses of fluopicolide. 2. Infants and children . Valent USA concludes that there is a reasonable certainty that no harm will result to the U.S. population (or any s ub - populations) by

including the incremental additional exposure resulting from the proposed uses o f fluopicolide.
