City of Ramsey <br /> Proposal QTB050246 <br /> January 19, 2017 <br /> Page 3 <br /> polynuclear aromatic hydrocarbons (PAHs) —5 samples; Benzene, Ethylbenzene,Toluene, Xylenes <br /> (BETX)—7 samples; gasoline range organics (GRO)—7 samples; and total Resource Conservation <br /> and Recovery Act (RCRA) metals - 5 samples. <br /> • Analyze 5 groundwater samples from the temporary wells for DRO and VOCs. <br /> • Analyze 3 soil gas samples from the temporary soil vapor probes for VOCs. <br /> • Prepare a Phase II ESA report summarizing the investigation results and providing <br /> recommendations for any additional investigation or response actions that may be required to <br /> address identified contamination during the planned future road and infrastructure improvements. <br /> Utility clearance and drilling services will be provided by licensed subcontract drilling firm. <br /> Laboratory analytical services will also be subcontracted. <br /> Task 2: UST Removal and Associated Demolition <br /> Braun Intertec will subcontract a licensed tank removal contractor to: remove and dispose of the <br /> concrete surfacing over the tanks; excavate and evacuate the USTs of all fluids and/or sludge (up to <br /> 500 gallons included in the stated price. Additional liquids will be disposed of at $2.00 per gallon <br /> and solids for$5.00 per gallon); evacuate and cap product lines; remove and dispose of the USTs; and <br /> import and place compactable backfill in the resulting excavations. All required notifications will be <br /> made and permits obtained prior to removal of the UST. All required access to mobilize, store, and <br /> utilize equipment at the Site will be provided by the property owner. <br /> This task does not include removal of the canopy, bollards, or restoration of the ground surface with <br /> asphalt or concrete. <br /> Task 3: UST Removal Monitoring and Sampling <br /> Braun Intertec will perform the following services during the removal of the UST system: <br /> • Conduct daily site visits to supervise and document the tank removal activities. <br /> • Conduct environmental monitoring and UST removal sampling after the tanks are removed from the <br /> ground. Exposed soil will be observed for the presence of visual and olfactory indications of <br /> contamination, and will be field screened using a photoionization detector(PID) equipped with a <br /> 10.6-eV lamp to monitor soil for the presence of organic vapors. The UST removal sampling will be <br /> conducted in accordance with Minnesota Pollution Control Agency(MPCA) Guidance document 3-01. <br /> • Collect one soil sample from below each end of each tank (8 samples). <br /> BRAUN <br /> I NTE RTEC <br />
