PUBLIC NOTICE Proposed No Further Action Determination Wilbur Ellis - Lodi 11701 West Woodbridge Road, Lodi, San Joaquin County California The Central Valley Regional Water Quality Control Board (Central Valley Environmental Water Board) invites public comment on a request for No Further Action by Protection Agency Wilbur Ellis at 11701 West Woodbridge Road Lodi (Site) shown on the Yana Garcia attached figure. Secretary of the Public Comment Period: 15 May 2024 through 15 June 2024 Environment CASE SUMMARY: Wilbur Ellis stored various agricultural solutions on an orchard owned separately at 11701 West Woodbridge Road in Lodi (Site). In March 2021 , a storage tank containing fertilizer solution, UAN-32, ruptured and released 6,000 gallons into surrounding soil and two surface water embankments. Water Boards The release caused elevated levels of ammonia and nitrogen in soil and State Water Resources one surface water drainage trench. Control Board In April and July 2021 , Wilbur Ellis conducted cleanup action at the Site. E. Joaquin Esquivel, Wilbur Ellis excavated 25,800 square feet of affected soil to a 4-foot depth, Chair collected confirmation soil samples, and analyzed for ammonia as nitrogen and nitrate as nitrogen. Two surface water samples were collected from the Regional Water Quality affected surface water drainage trench and analyzed for ammonia as Control Board, nitrogen. Central Valley Region Wilbur Ellis has sufficiently removed impacted soils and the footprint of Mark Bradford, Chair originally affected soils are below cleanup objectives for the Site of 100 milligrams per kilogram (mg/kg) of nitrate and ammonia as nitrogen. One surface water sample in the drainage trench contained 49 milligrams per liter (mg/L) of nitrate exceeding the maximum contaminant level (MCL) Contact: of 10 mg/L for nitrate in drinking water. The surface water drainage trench is Isabella Hagopian intended for excess water from crops augmented by fertilizer and therefore (916) 464-4776 will likely remain elevated for constituents known to be contained in Regional Water Quality fertilizers like nitrogen and ammonia. In addition, two heavy rainfall winters Control Board, have occurred since the last sample was collected, and exceeding Central Valley Region concentrations of ammonia as nitrogen in the surface water drainage trench are unlikely to remain. H la. Isabelagopian@ sate la. s.ca.gov On 1 November 2021 , Wilbur Ellis submitted the Cleanup Action Report (Closure Request) that includes a request for regulatory closure of the Site (No Further Action). Central Valley Water Board staff reviewed the Closure Request and based on the soil and surface water concentrations believe there is merit to the request.
