CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br />CENTRAL VALLEY REGION <br />MONITORING AND REPORTING PROGRAM NO. 5-01-841 <br />FOR <br />WOOLSEY OIL COMPANY <br />BULK FUEL PLANT <br />SAN JOAQUIN COUNTY <br />The Woolsey Oil Company bulk fuel plant (site) is at 930 Victor Road in Lodi. There are five 12,000 - <br />gallon aboveground storage tanks (AGTs) containing diesel fuel, one 1,000 -gallon AGT containing <br />kerosene, and one 275 -gallon AGT containing solvents. Historic petroleum hydrocarbon releases have <br />contaminated soil and groundwater at the site with petroleum hydrocarbons and associated fuel <br />constituents, including benzene and methyl tertiary butyl ether (MTBE). Free product is consistently <br />present in well MW -8. Woolsey began groundwater monitoring in 1995, which continues on a quarterly <br />and semi-annual basis. <br />This Monitoring and Reporting Program (MRP) is issued pursuant to Section 13267 of the California <br />Water Code and is designed to delineate groundwater contaminant plumes and determine whether <br />remediation efforts are effective. The Discharger shall not implement any changes to this MRP unless and <br />until a revised MRP is issued by the Executive Officer. <br />Prior to construction of any new groundwater monitoring or extraction wells, the Discharger shall submit <br />plans and specifications to the Board for review and approval. Once installed, all new wells shall be <br />added to the monitoring program and shall be sampled and analyzed according to the table below. <br />GROUNDWATER MONITORING <br />As shown on Figure 1, there are currently 9 monitoring wells onsite and offsite. Woolsey abandoned <br />MW -1 in January 2001, so it is not included in the MRP. All wells shall be monitored for depth to <br />groundwater and the presence of free product on a quarterly basis. The groundwater monitoring program <br />for wells MW -2 through MW -10 and any wells installed subsequent to issuance of this MRP, shall <br />include the list below. Monitoring wells with free product or visible sheen shall be monitored for free <br />product thickness and depth to groundwater only. Sample collection and analysis shall follow standard <br />EPA protocol. <br />
