CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD CENTRAL VALLEY REGION MONITORING AND REPORTING PROGRAM NO. R5-2008-XXXX CALIFORNIA WATER CODE SECTION 13267 FOR SPRECKELS SUGAR COMPANY, INC. FORMER HOLLY SUGAR FACILITY HOLLY DRIVE, TRACY D SAN JOAQUIN COUNTY Spreckels Sugar Company, Inc. (Spreckels) owns a sugar beet processing facility on Holly Drive in Tracy. Holly Sugar previously operated the facility, but in 2000, Spreckels purchased Holly Sugar. Spreckels is hereafter referred to as Discharger. In November 1990, about 500 to 800 gallons of No. 6 fuel oil spilled from a 420,000-gallon aboveground storage tank (AGT) in the northeast corner of the facility. The groundwater is about eight feet below ground surface and contains up to 2,000 micrograms per liter (pg/L) of total petroleum hydrocarbons (TPH) as fuel oil. This pollution impaired the beneficial use of this water resource. Spreckels emptied the tank in 1997 and no longer operates it. In 2005, the Discharger installed three groundwater monitoring wells and has sampled them sporadically. This Monitoring and Reporting Program (MRP) is issued pursuant to Section 13267 of the California Water Code and is necessary to delineate groundwater pollutant plumes and determine whether remediation efforts are effective. Existing data and information n about the Site show the presence of various chemicals, including TPH, emanating from the property under the control of the Discharger. The Discharger shall not implement any changes to this MRP unless and until a revised MRP is issued by the Executive Officer. 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 Regional Water Board for review and approval. r Once installed, all new wells shall be added to the monitoring program and shall be 11� sampled and analyzed according to the schedule below. GROUNDWATER MONITORING As shown on Figure 1, there are three monitoring wells at the Site (MW-FO-1 through MW-FO-3). The groundwater monitoring program for the 3 monitoring wells and any wells installed subsequent to the issuance of this MRP, shall follow the schedule below. T Monitoring wells with free phase petroleum product or visible sheen shall be monitored, I at a minimum, for product thickness and depth to water. Sample collection and analysis shall follow standard EPA protocol.
