Our observations and analytical results are summarized in this letter. <br /> Two USTs were removed on October 21,2004 from the site. The USTs were located on the west <br /> side of the home located at 2625 North Shore Drive in Minnetonka,Minnesota. The USTs were <br /> 300 gallons in capacity and reportedly contained heating oil. The USTs were removed by Dean's <br /> Tank,Inc. (Tank Contractor Certification Number 475). The tanks upon removal had no holes and <br /> appeared to be in good condition. The bacicfill material around the former tank and the native soil <br /> observed in the excavation was sand. <br /> During the tank removal,a small amount of product spilled out of the tanks. The impacted soil was <br /> excavated and hauled off site by Dean's Tank. Soil samples were collected from the impacted soil for <br /> disposal purposes. After the impacted soil was removed from the site,a confirmation soil sample was <br /> collected from the bottom of the excavation <br /> Soil from the excavation was screened by a Braun Intertec field technician using a 10.2 eV <br /> photoionization detector(PID)and organic vapor headspace techniques. Samples for headspace <br /> screening were collected from each of the excavation walls and from the excavation bottoms. No <br /> organic vapors were detected by headspace analysis,after the impacted soil had been removed from <br /> the excavation. <br /> The soil sample collected from the bottom of the excavation beneath the tank was submitted for <br /> chemical analysis of volatile organic compounds(VOCs),diesel-range organics(DRO)and gasoline- <br /> range organics(GRO). No VOCs,DRO or GRO were detected in the soil sample collected. Ttie <br /> complete laboratory analytical report is attached. <br /> Under Minnesota Pollution Control Agency(MPCA)guidelines,no further action is required with <br /> regard to this tank excavation. One copy of this letter should be filed with the legal papers for the <br /> properiy and the owner of the former tank should keep one copy on file. The owner of the former tank <br /> can use this letter as documentation that no environmental impact was encountered during removal. <br /> In performing its services,Braun Intertec uses that degree of care and skill ordinarily exercised under <br /> similar circumstances by reputable members of its profession practicing in the same locality.
