CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> MONITORING AND REPORTING PROGRAM NO. 5-01-815 <br /> FOR <br /> EQUILON ENTERPRISES LLC <br /> STOCKTON BULK FUEL PLAN <br /> STOCKTON, SAN JOAQUIN COUNTY <br /> The Equilon Bulk Fuel Terminal is at 3515 Navy Drive on the northeastern portion of Rough and <br /> Ready Island in Stockton(site). Facility operations,which began in 1940, have resulted in <br /> petroleum hydrocarbon pollution of soil and groundwater beneath the facility. Groundwater is <br /> first encountered at about 10 feet below ground surface. Local groundwater flow is generally to <br /> the west-southwest. <br /> This Monitoring and Reporting Program(MRP) is issued pursuant to Section 13267 of the <br /> California Water Code and is designed to delineate groundwater pollutant plumes beneath the <br /> site and determine whether remediation efforts are effective. Equilon Enterprises,LLC (hereafter <br /> Discharger) shall not implement any changes to this MRP unless and until a revised MRP is <br /> issued by the Executive Officer. This MRP replaces the requirements listed in MRP No. 94-801, <br /> which was issued on 10 February 1994. <br /> Prior to construction of any new groundwater monitoring or extraction wells,the Discharger shall <br /> submit plans and specifications to the Board for review and approval. Once installed, all new <br /> wells shall be added to the monitoring program and shall be sampled and analyzed according to <br /> the schedule below. <br /> GROUNDWATER MONITORING <br /> Figure 1 shows there are 31 groundwater monitoring wells at the facility. Except for DW-2, all <br /> the monitoring wells are screened in the shallow groundwater zone. Monitoring wells with free <br /> phase petroleum product or visible sheen shall be monitored for product thickness and depth to <br /> groundwater only. Tables 1 and 2 show the constituents of concern (COCs) and the sampling <br /> frequencies for the 31 monitoring wells. Any wells installed subsequent to the issuance of this <br /> MRP shall be monitored quarterly. Sample collection and analysis shall follow standard EPA <br /> protocol. <br />
