WASTE DISCHARGE REQUIREMENTS ORDER R5-2013-0028 -38- DELICATO VINEYARDS, INC. DELICATO FAMILY VINEYARDS SAN JOAQUIN COUNTY Compliance with these limitations shall be determined annually based on an approved intrawell statistical analysis that uses methods prescribed in Title 27, Section 20415(e)(8). This limitation requires intrawell analysis (comparing the well to historic data collected at the well rather than an upgradient well). H. Provisions: 1. The following reports shall be submitted pursuant to CWC section 13267 and shall be prepared as described in Provision HA: a. By 1 May 2013, the Discharger shall submit a Wastewater Pond Design and Pond Liner Construction Quality Assurance (CQA) Plan, and an Unlined Wastewater Pond Closure Plan. The pond design report shall specify the final design of the new wastewater storage ponds and liner systems, including complete pond geometry, liner materials, liner thickness, seaming methods, and details of anchorage and typical penetrations. The CQA workplan shall describe the specific construction quality assurance procedures and test methods that the Discharger proposes to ensure and verify that the liner subgrade preparation, installation and seaming will comply with the specifications; the entire liner is tested following installation to verify that all seams and liner penetrations are leak-free at the time of acceptance; and the entire liner is inspected for visible material defects and construction damage such as holes or tears prior to acceptance. The Unlined Wastewater Pond Closure Plan shall describe the proposed plan to close the existing two-acre unlined wastewater ponds and convert the area for supplemental irrigation water storage. The closure plan shall describe the specific means that will be implemented to prevent percolation of residual waste constituents in the soil underlying the former wastewater ponds, including proposed procedures to remove sludge and waste- containing sediments, provide verification of waste removal, plans for disposal of those materials, and plans for placement of clean fill or other lining material to reduce the percolation rate beneath the former pond(s). b. By 1 July 2013, the Discharger shall submit a Groundwater Monitoring Well Installation Workplan that describes plans to install an appropriate number of monitoring wells beneath the expanded LAAs to verify compliance with the Groundwater Limitations. The workplan shall be prepared in accordance with, and include the items listed in, the first section of Attachment D: "Requirements for Monitoring Well Installation Workplans and Monitoring Well Installation Reports", which is attached hereto and made part of this Order by reference. The groundwater monitoring wells shall be designed to yield samples representative of the uppermost portion of the first aquifer underlying the LAAs.
