CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> MONITORING AND REPORTING PROGRAM NO. R5-2008-0149-010 <br /> FOR <br /> IN-SITU GROUNDWATER REMEDIATION AT SITES WITH VOLATILE ORGANIC <br /> COMPOUNDS, NITROGEN COMPOUNDS, PERCHLORATE, PESTICIDES, <br /> SEMI-VOLATILE COMPOUNDS AND/OR PETROLEUM HYDROCARBONS <br /> FOR <br /> PARKINSON'S HAMMER 1-5 ARCO <br /> 3250 WEST HAMMER LANE, STOCKTON <br /> SAN JOAQUIN COUNTY <br /> This Monitoring and Reporting Program (MRP) describes requirements for monitoring a <br /> groundwater extraction and/or treatment system. This MRP is issued pursuant to Water Code <br /> Section 13267, and has been prepared based on Attachment C, a part of General Order <br /> R5-2008-0149. <br /> No changes to this MRP shall be implemented unless and until a revised MRP is issued by the <br /> Executive Officer of the Central Valley Water Quality Control Board (Board). As appropriate, <br /> Board staff shall approve specific sample station locations prior to implementation of sampling <br /> activities. <br /> PROJECT <br /> 1. Parties Submitting a Notice of Intent under General Order R5-2008-0149: <br /> Mr. Wesley Parkinson (herein referred to as "the Discharger"). <br /> 2. Project Location: The project is a service station/convenience store in the city of Stockton, <br /> San Joaquin County, Township/Range/Section 2N, 6E, S18, MDB&M. The assessor parcel <br /> number is 082-400-09. <br /> 3. Project Description: Vehicle fueling operations at the Parkinson's Hammer 1-5 have <br /> caused pollution of soil and groundwater by petroleum constituents. The primary <br /> constituents are total petroleum hydrocarbons as gasoline (TPHg), benzene, toluene, <br /> ethylbenzene, and xylenes (BTEX), and methyl tert-butyl ether (MtBE). The petroleum <br /> impacts were found during product piping and dispenser upgrades at the site in January <br /> 2000. From 2000 to 2006, a number of soil and groundwater investigations were <br /> completed. Limited remedial measures have been conducted in the past that include soil <br /> over-excavation and dual-phase extraction pilot testing. Although the previous remedial <br /> efforts were moderately successful, it has been determined that additional remedial efforts <br /> are required to more expeditiously and cost-effectively clean up the residual impacts to <br /> groundwater beneath the site. <br /> The Discharger proposes to conduct a limited in-situ chemical oxidation injection pilot study <br /> (using ozone [03] and hydrogen peroxide [H2O21) to be followed by full-scale <br />
