MONITORING AND REPORTING PROGRAM NO. R5-2014-0815 - 3 - NESTLE USA, INC. - RIPON SAN JOAQUIN COUNTY (11) City of Ripon municipal supply wells, 17 private domestic drinking water supply wells, one (1) private irrigation well, one (1) school drinking-water supply well, two (2) school irrigation wells, four (4) Diamond Pet Food industrial supply wells, and one (1) California Department of Transportation irrigation well. The Monitoring Program for these wells and any wells installed subsequent to the issuance of this Order shall comply with the schedule below. The well locations are presented on attached Figure 1. 11.This Monitoring and Reporting Program (MRP) is issued by the Central Valley Water Board, pursuant to California Water Code (CWC) section 13267 and is necessary to delineate the groundwater volatile organic compound (VOC) plume, to determine whether remediation efforts are effective, to monitor effluent quality, and to provide early detection of VOCs in private and municipal supply wells. 12.Existing data and information about the Site show the presence of various VOCs, including TCE, cis-1,2-dichloroethene (cis-1,2-DCE), trans-1,2-dichloroethene (trans-1,2-DCE), vinyl chloride (VC), methylene chloride, chloroform, and bromoform, emanating from the property and resulting from the Discharger's past decaffeination operations. The Discharger is responsible for the discharge because the Discharger owned and operated the decaffeinated instant coffee manufacturing plant that discharged TCE to soil and groundwater at the Site, and to the City of Ripon industrial sewer system. 13.The Discharger shall not implement any changes to this MRP unless and until a revised MRP is issued by the Executive Officer. This MRP replaces the requirements listed in MRP No. R5-2010-0810, which is hereby rescinded. 14.Prior to construction of any new groundwater monitoring or extraction wells, and prior to destruction of any groundwater monitoring or extraction wells, the Discharger shall submit plans and specifications to the Central Valley Water Board for review and approval. Once installed, all new wells shall be added to the monitoring program and shall be sampled and analyzed according to the schedule below. LEGAL PROVISIONS 15.CWC section 13267 states, in part: (b)(1) In conducting an investigation, the regional board may require that any person who has discharged, discharges, or is suspected of having discharged or, discharging, or who proposes to discharge waste within its region . . . shall furnish, under penalty of perjury, technical or monitoring program reports which the regional board requires. The burden, including costs, of these reports shall bear a reasonable relationship to the need for the report and the benefits to be obtained from the reports. In requiring those reports, the regional board shall provide the person with a written explanation with regard to the need for the reports, and shall identify the evidence that supports requiring that person to provide the reports.
