Problems/Comments
Two 5,000 gallon gas USTs were removed from the site in 1998, but the associated piping was left in place. During the tanks removal in 1998, the excavations were backfilled with decommissioned building debris. On August 3, 2007, a site characterization, as well as removal of debris and piping was performed. The area of the former USTs was partially excavated to a depth of 4 feet bgs in efforts to remove debris. Confirmation soil samples from the depths of the excavation indicate the presence of contaminates, but below ADEC cleanup levels. The piping, which was located at 1 foot bgs, was removed. Confirmation soil samples collected from underneath the piping, at 1.5 feet bgs, indicate benzene contamination up to 0.0322 mg/kg. Groundwater was not encountered during all the excavation activities. An old abandoned drinking water well remains 100 to 200ft upgradient of the former USTS. Excavated piping remains on the concrete pad at site as of 5/21/09. This site also had a reportedly (separate) spill event in 1985 in which approximately 10,000 gallons of gas may have spilt due to broken fuel lines, but there is no evidence the spill actually occurred. Therefore this spill event, which is tracked under the file name Lake Louise Junction Cafe, Hazard ID 678, file # 2237.38.001, is non-qualifying.

| 5/21/2009 | Site Visit | ADEC performed a site inspection on this date. The piping removed during the 2007 assessment was observed on the concrete pad. A shovel sheen test was performed at a down gradient surface water area, west of the former USTs. No signs of contamination were evident. The abandoned disconnected drinking water well was located approximately 100-200 ft. north east of the former USTs. | Grant Lidren |
| 6/10/2009 | Cleanup Complete Determination Issued | The Alaska Department of Environmental Conservation (ADEC), Contaminated Sites Program, has completed a review of the environmental records associated with the Former Lake Louise Convenience Store. Based on the information provided to date, the ADEC has determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment, and the site will be closed. | Grant Lidren |
