Problems/Comments

This site has historically been used for airline services including passenger and cargo operations, fuel storage, vehicle maintenance, and airplane fueling. The terminal was constructed in 1978 then destroyed by fire in 2005. The site consisted of a passenger and cargo terminal, restaurant, a metal shop building, a fuel aboveground storage tank farm (AST), two fuel cabinets, a 55-gallon drum fuel dispensing station, and an unpaved parking area and a gravel ramp. The primary area of concern is the AST farm located on the northwest quadrant of Lot 4. This historic 80 by 100 foot unlined bermed fuel storage tank farm area consisted of the following: one 20,000 gallon aviation gasoline AST; one 20,000 gallon Jet A AST; and one 200,000 gallon Jet A AST with associated piping and dispensers. The ASTs and associated piping were removed between 1997 and 2002. Currently, the site consists of an asphalt apron, the new Frontier Air Hangar and the historic metal shop building.

1/8/2010	Meeting or Teleconference Held	Teleconference with DEC staff Pam Clemens and Bill O’Connell; DOT staff Penny Adler, Colette Foster, Jennifer Kuentzel, and Sam Myers; and Brandon Carlson from Delta Leasing representing Frontier Flying Service. We discussed the proposed construction of a 140’ by 90’ hangar on Lots 4 and 5 of Block 100 at the Barrow Airport. Frontier Flying Services would like to complete the construction of the hangar in the summer of 2010. It will be used for storage of a large helicopter and other equipment. Delta Leasing had proposed using thermal tubes or a thermo-siphon system, a liner under 1 foot of foam and interlocking slabs on grade with pier blocks as a foundation. We discussed the need of a sampling plan for a minimum of five test pits, the use of a hydrocarbon resistant liner, and a contaminated soils handling plan; all to be approved by ADEC prior to beginning this project.	Pam Clemens
4/14/2010	Document, Report, or Work plan Review - other	Reviewed work plan for additional characterization during site development at Lot 5. Up to six soil samples will be collected to delineate the extent of contamination on this lot after site grading and before development. Soil that is excavated at the site during development activities will be incorporated into the runway expansion project by ADOT at the Barrow Airport. ADOT has also indicated that Lot 4 will be paved (see action dated 8/17/07) as part of site development activities.	Bill O'Connell
7/9/2010	Document, Report, or Work plan Review - other	Reviewed the electronic copy of the ChemTrack Sampling report prepared for Delta Leasing titled: Hangar Excavation Analytical Sampling Report; at the Wiley Post / Will Rogers Memorial Airport Barrow, Alaska for the Markair - Barrow site.

4/8/2015	Institutional Control Update	Provided approval to Ravn Project (current lessee) for installation of a helicopter pad and a birdhouse. The helicopter pad will require a small area of the cap to be removed and replaced. They do not believe they should have to dig in the soil under the cap at all. I requested that photos of the area of the cap that had to be replaced be provided when the project is complete. I've set the reminder system to check with Ravn Project at the end of this summer if we have not heard from them yet.	Evonne Reese
2/2/2016	Institutional Control Compliance Review	IC compliance review conducted as part of the communications with Ravn Alaska regarding construction work on this property. The work is completed and the asphalt cap was not disturbed. The internal reminder system has been set for five years from now to verify the land use conditions.	Evonne Reese
8/18/2016	Institutional Control Update	ADOT reported on their spring 2013 investigation of Ahkovak St, in Barrow, Alaska. One of their test holes (TH13-611) encountered some soil with a strong diesel smell. The contamination appears to be historic from the Cleanup Complete - Institutional Controls site known as MarkAir - Barrow. The Utility & Right-of-Way Guidance document was provided to ADOT to use on their road project in this area. The project will occur in the next couple of years. During that time, contaminated soil associated with the MarkAir - Barrow site will need to be handled and/or transported appropriately. Characterizing the soil prior to construction may be an option. ADOT will continue working with ADEC throughout this project.	IC Unit
5/19/2017	Institutional Control Compliance Review	IC compliance review conducted. Closure/IC Details updated.	Kristin Thompson
11/9/2017	Institutional Control Periodic Reporting	Received the 5-year land status report with confirmation that there have been no changes to the land use or ownership at this site. A letter was issued documenting receipt of the report and re-documenting the ICs for future reviews.	Kristin Thompson
11/16/2022	Institutional Control Compliance Review	Received the 5-year land status report with confirmation that there have been no changes to the land use or ownership at this site.

On this date, ADEC received the Bioremediation activities Former Mark Air Facility submitted by S & W, dated October 2003. Field activities included: removing the two 20,000-gallon ASTs and associated pipelines; advancing two soil borings in the NW and NE quadrants of the containment area; and excavating 930 cubic yards of soil from the ground -amending with nutrients and enzymes -and returning to the excavations. Groundwater was generally encountered 3 to 4 feet bgs with frozen ground at 4 feet bgs. Petroleum odors were noted in all the excavations and the borings. Soil samples collected from the two borings at a depth of 2 feet bgs did not detect contaminants above cleanup levels. Soil samples collected under the former pipeline at 3 feet bgs contained GRO up to 562 mg/kg, DRO up to 3,080 mg/kg, and benzene up to 0.243 mg/kg. The soil excavations and eventual landfarming occurred at two areas: the Former Avgas Dispenser and the AST containment area (note: soil was not excavated at the former Jet-A fuel dispenser island to prevent damaging the sidewalk and apron). At the Former Avgas Dispenser area a 30 ft* 40ft * 3ft bgs area was excavated with an additional 10 ft *10ft * 2ft bgs at the historic D12 hotspot. Three soil confirmation samples collected contained GRO up to 1,990 mg/kg, DRO up to 1,360 mg/kg, benzene up to 15.7 mg/kg, toluene up to 208 mg/kg, ethylbenzene up to 25.4 and xylenes up to 104 mg/kg. At the AST containment area, a 50 ft *54ft* 4ft bgs area was excavated. Groundwater in the southern portion of the excavation contained a yellowish color. Nine confirmation soil samples collected contained GRO up to 1,690 mg/kg, DRO up to 26,400 mg/kg, benzene up to 3.16 mg/kg, toluene up to 316 mg/kg, ethylbenzene up to 40.5, and xylenes up to 104 mg/kg.

Teleconference with DEC staff Pam Clemens and Bill O’Connell; DOT staff Penny Adler, Colette Foster, Jennifer Kuentzel, and Sam Myers; and Brandon Carlson from Delta Leasing representing Frontier Flying Service. We discussed the proposed construction of a 140’ by 90’ hangar on Lots 4 and 5 of Block 100 at the Barrow Airport. Frontier Flying Services would like to complete the construction of the hangar in the summer of 2010. It will be used for storage of a large helicopter and other equipment. Delta Leasing had proposed using thermal tubes or a thermo-siphon system, a liner under 1 foot of foam and interlocking slabs on grade with pier blocks as a foundation. We discussed the need of a sampling plan for a minimum of five test pits, the use of a hydrocarbon resistant liner, and a contaminated soils handling plan; all to be approved by ADEC prior to beginning this project.

Institutional Control Update

ADOT reported on their spring 2013 investigation of Ahkovak St, in Barrow, Alaska. One of their test holes (TH13-611) encountered some soil with a strong diesel smell. The contamination appears to be historic from the Cleanup Complete - Institutional Controls site known as MarkAir - Barrow. The Utility & Right-of-Way Guidance document was provided to ADOT to use on their road project in this area. The project will occur in the next couple of years. During that time, contaminated soil associated with the MarkAir - Barrow site will need to be handled and/or transported appropriately. Characterizing the soil prior to construction may be an option. ADOT will continue working with ADEC throughout this project.
