U <br /> REMEDIAL ACTION PLAN ADDENDUM#1 ! <br /> USA PETROLEUM STATION#65 <br /> FEBRUARY, 1996 <br /> A list of tasks required to implement this RAA and the associated costs for each task are <br /> summarized in the following section f <br /> 4 <br /> System Design $ 2,300.00 <br /> Permitting $ 1,450A0 <br /> Trenching and Repaving $ 3,750.00 <br /> Construction Management $ 2,100.00 <br /> Materials $ 4,150.00 <br /> SVE System Rental (2 months) $ 6,000.00 <br /> System Startup $ 1,880.00 <br /> System Maintenance $ 1,360.00 <br /> The estimated cost for this RAA is approximately $23,000.00. Please note that this cost is in <br /> addition to the quarterly groundwater monitoring costs at the site. <br /> OPTION III Excavation With Off-Site Disposal/Treatment <br /> Based on the previous investigations, it is estimated that the hydrocarbon impacted soil extends to <br /> a depth of up to 50-feet bgs. Due to the location of the hydrocarbon impacted soil zone, <br /> excavation activities would require removal of the USTs,product piping and aboveground <br /> structures. The major physical obstructions associated with this option,combined with the <br /> excessive cost and loss of daily retail operations makes this RAA economically unattractive. <br /> r <br /> The cost of implementing this RAA is summarized below: <br /> Demolition of Service Station $ 21,000.00 <br /> Removal of Asphalt and Concrete Surface $ 2,500.00 h <br /> Excavation of Impacted Soil (Assume 40' X 40'X 50') $ 65,000.00 <br /> Import Fill and Compaction Testing $ 120,000.00 <br /> t <br /> Resurface Area with 4-inch Asphalt $ 18,000.00 <br /> 3 <br />
