I CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD CENTRAL VALLEY REGION MONITORING AND REPORTING PROGRAM NO . R5-2008-0149-017 FOR IN -SITU GROUNDWATER REMEDIATION AT SITES WITH VOLATILE ORGANIC COMPOUNDS , NITROGEN COMPOUNDS , PERCHLORATE , PESTICIDES , SEMI -VOLATILE COMPOUNDS AND/OR PETROLEUM HYDROCARBONS FOR KING ISLAND RESORT/WESTREC PROPERTIES / PS MARINAS 5 11530 WEST EIGHT MILE ROAD , STOCKTON SAN JOAQUIN COUNTY This Monitoring and Reporting Program ( MRP) describes requirements for monitoring an ozone injection system . This MRP is issued pursuant to Water Code Section 13267 , and has been prepared based on Attachment C , a part of General Order R5-2008-0149 . No changes to this MRP shall be implemented (except sample location/frequency) unless and until a revised MRP is issued by the Executive Officer of the Central Valley Water Quality Control Board (Board ). As appropriate, Board staff shall approve specific sample station locations prior to implementation of sampling activities . PROJECT 1 . Parties Submitting a Notice of Intent under General Order R5-2008-0149: Westrec Properties / PS Marinas 5 (hereafter referred to as the " Discharger") . 2 . Project Location : The project is a boat marina on Honker Cut at Disappointment Slough near the city of Stockton , San Joaquin County, Township/Range/Section 2N , 5E , S5 , Mount Diablo Base & Meridian . The assessor parcel number is 071 - 190-06 . 3 . Project Description : Marina fueling operations at the King Island Resort have caused pollution of soil and groundwater by petroleum constituents . The primary constituents are total petroleum hydrocarbons as gasoline (TPHg ), TPH as diesel (TPHd ), benzene, toluene, ethylbenzene , and xylenes (BTEX) , methyl tert-butyl ether (MtBE ), and tertiary butyl alcohol (TBA) . The petroleum impacts were found after an investigation at the site in 1989 . Removal of underground storage tanks ( UST) occurred between 1991 and 1999 . From 1989 to present, a number of soil and groundwater investigations have been completed . A past remedial measure consisted of soil over-excavation . Although the previous remedial efforts were moderately successful , it has been determined that additional remedial efforts are required to more expeditiously and cost-effectively clean up the impacts to groundwater. The Discharger proposes to conduct a limited pilot study, to be followed by full implementation depending upon the success of the pilot study, for remediating the existing petroleum impacts using in-situ chemical oxidation . The Discharger proposes to inject
