9/13/2007 Update or Other Action Staff reviewed and approved a proposal for an area-wide groundwater investigation at the Kotzebue Airport. Shannon and Wilson will review the CS file for Markair and LUST files for AK air, Northwest Aviation, Crowley (Lot 1, Block 4), and ADOT&PF to determine data gaps. A work plan will then be put together to fill those data gaps to the extent possible with the funding restraints. A new hard file was created to track the area-wide activities (410.38.021). Database entries will be entered under Markair until further information is acquired. Ann Farris
9/27/2007 Update or Other Action Staff contacted property owners and leasees at the Kotzebue Airport to request permission to do sampling as part of the airport area-wide investigation. Shannon and Wilson expects drilling to begin on October 22, 2007, assuming access is granted. Ann Farris
10/19/2007 Update or Other Action Access was not given as DOT could not provide adequate utility locates and had concerns about drilling on the taxiway. Also northwest aviation was unresponsive. The project is being reevaluated. A site visit will be planned for the spring to determine acceptable drilling locations. Also the scope of work will be revisited. Ann Farris
2/21/2008 Update or Other Action Staff met with Shannon and Wilson to discuss the planned site visit and direction of the project. This fiscal year we will focus on teh site visit and the work plan. Any drilling activities will be postponed until next fiscal year. Ann Farris

12/30/2010 Update or Other Action This site has been split. Lot A - Markair Former Terminal Building is currently a DOT facility tracked under ADOT&PF Maintenance Station- Kotzebue Airport (File 410.26.009) Markair Lot C-D (former Cargo Building) is tracked under this site name. Tamara Cardona-Marek
6/17/2016 Update or Other Action Reviewed file to determine site status. Laura Jacobs
3/17/2017 Update or Other Action DEC received call from consultant acting on behalf of lessees, Marcia and Mark Fairbanks, doing business as FBX. Consultant was working on a Phase I assessment for the Fairbanks couple who are now operating a parcel business out of the Former MarkAir Cargo Building. Laura Jacobs
4/7/2017 Meeting or Teleconference Held DEC met with Penny Adler, Sam Myers, and Mike McCarroll at DOT to discuss contamination associated with the Kotzebue Airport. During the meeting, DEC discussed what is known about petroleum-contaminated water and migration to the Kotzebue Sound and the Lagoon. DEC is no longer investigating the contamination through state funding, and will be working with lease lot RPs to identify the sources of contamination and attempt to cleanup contamination through source removal. Lease agreements, lease lot histories, and deterrents to investigations were discussed. It was revealed by DOT&PF Airport Environmental staff that there was an unreported 5-gallon spill of diesel 6/11/2008 at this site. The contaminated soils were dug up and placed on a liner, with no other information given. Airport Leasing staff shared database of lease and contracts for the Kotzebue Airport, in which the FBX business also, for a time, dispensed aviation fuels and lubricants. Laura Jacobs
8/30/2017 Update or Other Action DEC drafted a letter to all contaminated site lessees and managers at the Kotzebue Airport to explain the unique challenges at the airport and DEC's planned approach to address these issues for all sites. Laura Jacobs
