cALiF6R#A REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> REVISED <br /> MONITORING AND REPORTING PROGRAM NO. 94-806 <br /> FOR D <br /> KINDER MORGAN ENERGY PARTNERS <br /> HOLT PETROLEUM RELEASE SITE <br /> SAN JOAQUIN COUNTY <br /> Kinder Morgan Energy Partners (formerly known as Santa Fe Pacific Pipeline Partners), hereinafter R <br /> referred to as Discharger, operates a underground petroleum pipeline that generally runs from the San 1 <br /> Francisco Bay area to Reno, Nevada. In February 1986, KMEP dispovered that a section of pipeline <br /> passing near Holt was breached and leaking its.contents. This spill site iq along Cook Road west of Holt <br /> and southeast of Trapper Slough just before it joins Whiskey Slough. The groundwater, which is about <br /> one to 12 feet below ground surface (bgs), and soil in this area are contaminated with a variety of <br /> constituents found in petroleum products including benzene and gasoline range total petroleum A <br /> hydrocarbons (TPH). <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 <br /> and until a revised MRP is issued by the Executive Officer. This MRP replaces the groundwater F <br /> monitoring requirements listed in the original MRP No. 94-806 dated 29 June 1994. <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 schedule below. T <br /> GROUNDWATER MONITORING <br /> As shown on Figure 1, there are currently 15 monitoring wells M-1, 2, 3, 8, 9 and 10, N-6, 7, 8, 15, 16, <br /> 17, 18 and 19, and 0-1. The groundwater monitoring program for these wells and any wells installed <br /> subsequent to issuance of this MRP, shall follow the schedule below. The volume and rate of extracted <br /> groundwater also shall be provided in quarterly monitoring reports. Sample collection and analysis shall <br /> follow standard EPA protocol. <br /> Analytical Maximum Sampling <br /> Constituent Method Detection Limit' Frequency <br /> Depth to water — --- Quarterly <br /> Benzene 8020 or 8260 0.5 µg/1 Quarterly <br /> Toluene 8020 or 8260 0.5 µg/1 Quarterly <br /> Ethylbenzene 8020 or 8260 0.5 µg/1 Quarterly <br /> Xylene 8020 or 8260 0.5 4g/1 Quarterly <br /> TPH-gasoline 8015M 50 µg/1 Quarterly <br /> TPH-diesel 8015M 50 µg/1 Quarterly <br /> Methyl t-butyl ether 8260 0.5 µg/1 Quarterly <br />
