Problems/Comments

Four underground storage tanks (USTs) on site. Tank #1, a 10,000-gallon aviation gasoline; Tank #2, a 4,000-gallon jet A, last use-diesel; Tank #3, a 1,000-gallon unleaded gasoline taken out of service and an unregulated 1,000-gallon heating oil tank which has been out of service for 20 years. A Site Assessment submitted by Shannon & Wilson May 27, 1994 indicates soil contamination near the dispenser island, and near the 1,000-gallon gasoline tank. The highest contamination was reported near the 1,000-gallon gasoline tank, 1,200 parts per million (ppm) GRPH and 38 ppm benzene. In 2006 the gasoline tank was removed and 10 cubic yards of contaminated soil were excavated and thermally treated. However a Phase II investigation indicates that soil and groundwater contamination has not been adequately delineated

2/24/2003	Update or Other Action	Reviewed file briefly due to information request concerning Lot 1 of Block 101. This lot appears to be a recent subdivision of Lot14A, Block 100. A 1994 site assessment indicated soil and possible groundwater contamination. The file indicates that a cleanup grant was applied for but not received. An ADEC letter required additional information on the status of a 1000 gallon tank that was to be removed and a release investigation for the observed contamination. No additional correspondence is available in the file.	Janice Wiegers
12/21/2005	Update or Other Action	Received call from Dave Guinn (IPP) regarding the 1,000 gallon gasoline tank. His files indicate it was never upgraded and he is working with Arctic Air the current leasee to have it removed. An out of service 1,000 gallon heating oil tank is located adjacent to the gasoline tank and should be removed at the same time.	Kim DeRuyter
5/8/2006	Update or Other Action	Proj Mgr request name change from FRONTIER FLYING SERVICE TO FIA - AIR ARCTIC (NORTHERN KOYUKUK) to reflect new lesee. Northern Air Tour Company is also run out of the Air Arctic facility.	Wendy Uzzell
5/8/2006	Site Visit	Accompanied Erik Sirs, EPA Region 10 UST inspector, Dave Guinn and Cheryl Paige (UST Program) on a site inspection to determine locations and status of tanks.

The UST Program is requiring removal of Tank #3, a 1,000 gallon gasoline tank on the SE corner of the property near the overhead power lines and the municipal sewer main. This tank is 34 years old, and out of compliance. Tanks #1 and #2 have been upgraded, and are monitored by a leak detection system. Two tanks were removed from service in the 1980’s. An unregulated 1,000 gallon heating oil tank and a 275 gallon day tank are still in service, and are easily located on the site map. The facility sits between University Ave and the East Ramp Tarmac, south of the FAA tower. The site is paved, city water is available, however, the file indicates a water well is in use at the facility.	Kim DeRuyter
2/20/2007	Update or Other Action	ADEC received the August 2006 Phase II site assessment report for the Air Arctic site. A 1,000-gallon gasoline tank was removed and approximately 10 cubic yards of contaminated soil was excavated and thermally remediated. The excavation was limited due to the proximity of the utility lines. Five confirmation soil samples were collected from the excavation from approximately 6.5 feet bgs. The contaminant levels ranged from 86.7 mg/Kg to 6,800 mg/Kg GRO. The benzene levels ranged from 0.0204 mg/Kg to 27.3 mg/Kg benzene. The depth to groundwater was 12 to 15' bgs.
