Infurna Jr. November 19, 1999 <br /> Senior REHS (revised January H, 2000) <br /> Leaking Underground Fuel Storage Tank Program <br /> San Joaquin County Public Health <br /> Environmental Health Division (PHS-EHD) <br /> 304 East Weber Ave., Third Floor <br /> Stockton, CA. 95202 <br /> (209) 468-3454 <br /> RE: Gasoline dispensing system removal and upgrade at Former Regal Station, located at 6425 <br /> Pacific Avenue, Stockton, California 95207. <br /> Dear Mr. Infurna: <br /> INTRODUCTION <br /> Lincoln Village Properties has taken ownership of the three existing upgraded underground storage <br /> tanks (USTs). Lincoln Village Properties intends to lease the site to Prestige Oil who will operate <br /> the site as a gasoline service station. Prestige Oil is going to remove and upgrade the existing UST <br /> dispensing system (product delivery piping and dispenser areas). Wickland (Western Geo- <br /> Engineers) will obtain the required documentation soil samples from beneath the removed piping <br /> (one sample per 20 liner feet) and from beneath each dispenser. Confirmation soil sample borings <br /> near the UST area, ongoing groundwater monitoring and vapor extraction monitoring indicated that <br /> the soils beneath this site have been remediatcd (contamination has been removed) and that no <br /> further actions are necessary. If gasoline contaminated soils are revealed during the piping removal <br /> and sampling, these areas will be over-excavated until field screening (photo-ionizing detector with <br /> a 10.2 ev bulb) indicates that the majority of contaminated soils have been removed (less than 50 <br /> ppmv PID from headspace of ziplock baggy). A maximum of 400 cubic yards of soil would be <br /> removed during the over-excavation, see Figure I — Site map with potential areas of excavating <br /> after product line removal. <br /> Wickland Properties had permitted the removal of the 3-10,000 gallon underground storage tanks <br /> and associated piping. Lincoln Village now plans to take ownership of the 3 USTs and will <br /> upgrade the dispensing system. Wickland will conduct the above mentioned confirmation <br /> sampling and the possible over-excavation. The empty tanks and associated piping, installed in <br /> January 1989, are doublewall fiberglasses had contained/dispensed unleaded regular and unleaded <br /> premium gasoline. EXXON removed the dispensers and all fluids from the piping and the UST's <br /> when they vacated the property in July 1998. <br /> I R-603 piping upgrade 1-2000 <br />
