CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD CENTRAL VALLEY REGION MONITORING AND REPORTING PROGRAM NO. R5-2007-0831 CALIFORNIA WATER CODE SECTION 13267 FOR KINDER MORGAN ENERGY PARTNERS, L.P. HOLT PETROLEUM RELEASE SITE 3851 SOUTH WHISKEY SLOUGH ROAD, HOLT SAN JOAQUIN COUNTY Kinder Morgan Energy Partners, L.P. (KMEP), hereafter Discharger, operates an underground petroleum pipeline that generally runs from the San Francisco Bay Area to Reno, Nevada. In February 1986, KMEP discovered that a section of its 10-inch diameter pipeline passing near Holt was breached during a flood and leaking its contents. The resulting groundwater pollution and cleanup site is at 3851 South Whiskey Slough Road west of Holt and southeast of Trapper Slough (Site). The soil and groundwater, which is about one to 12 feet below ground surface (bgs), are polluted with a variety of constituents found in petroleum fuel products. This pollution impaired the beneficial use of this water resource. KMEP previously operated a groundwater extraction and treatment system and soil vapor extraction treatment system at the Site and is now conducted monitored natural attenuation. 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 about the site show the presence of various chemicals, including benzene, ethylbenzene, toluene, xylenes, and gasoline and diesel range total petroleum hydrocarbons, emanating from the property resulting from the Discharger's operation. 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. R5-2004-0803, which was issued on 29 January 2004. 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 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. GROUNDWATER MONITORING As shown on Figure 1, there are 19 groundwater monitoring wells, designated M-1, M-2, M-3, M-8, M-10, N-7, N-8, N-15, N-16, N-17, N-18, N-19, N-20, 0-1, RW-1, N-21, N-22, N-23, and N-24, Deep wells N-21 through N-23 are scheduled for destruction. The groundwater monitoring program for the 16 monitoring wells (all except three deep wells) and any wells installed subsequent to the issuance of this MRP, shall follow the schedule below. Monitoring wells with free phase petroleum product or visible sheen shall be monitored, at a minimum, for product thickness and depth to water. Sample collection and analysis shall follow standard EPA protocol.
