(Nova) at the above referenced site in order to confirm tank removal observations. <br /> A Nova representative was on—site March 15, 1992 to collect a soil sample from the base of the <br /> excavation at tt�e residence of Mrs. Oskie in Orono, Minnesota. A 3,000 gallon fuel oil tank had <br /> t�een removed by Mr. Ron Graves. The tank was observed to be in very good condition. No <br /> �vidence of a petroleum release was observed. <br /> A soil sample was collected from the base of the excavation and screened for the presence of <br /> organic vapors using a photoionization detector(PID) and the jar headspace test method. Organic --� <br /> vapors were not detected with the PID. <br /> One soil sample was submitted to Minnesota Valley Testing Laboratories on March 17, 1992 for <br /> analysis of benzene, ethyl benzene, toluene, xylenes (BETX), and total petroleum hydrocazbons <br /> (TP� as fuel oil in accordance with Minnesota Pollution Control Agency (MPCA) guidelines. <br /> L.aboratory results indicate petroleum hydrocarbon constituents were not detected above the <br /> method detection limits. A copy of the laboratory report is attached. <br /> Based on �ield observations and laboratory results, a petroleum release did not occur from the <br /> fuel oil tank removed from the Oskie residence in Orono, Minnesota. <br />
