Problems/Comments
The St. Mary's Airport (KLM) was transferred from the Bureau of Land Management (BLM) to the State of Alaska Department of Transportation in 1978. That year, Delta Development (the lessee) requested permission for space to relocate a 10,000-gallon Aviation Gasoline (AvGas) tanks and permission to sell AvGas to the public. The aircraft hangar was constructed in 1980. The site was then leased to Hermans' Aviation, which was purchased by MarkAir Express around 1990. Throughout the history of the site, the lessees had a reputation for poor housekeeping on the lot, revealed in correspondence with DOT. The size of the lot and naming conventions also changed throughout time. The lessee had an auto body shop on the property that was added on in the 1980s. In 1992, MarkAir filed for Chapter 11 bankruptcy, but MarkAir continued to operate at the site. In July 1993, an approximately 1,000-gallon diesel fuel release occurred in the area on the north and eastern sides of the building on Lot 5C. The release likely occurred from the overfilling of an aboveground storage tank (AST). Other sources of contamination may have included spillage from leaking drums located on the site or spillage from a tanker truck. A diesel-powered generator, space heaters, piping, aircraft, and heavy equipment were also stored on-site. In response to the release, approximately 50 cubic yards of soil were excavated and stored on a polymeric liner. A Phase II Environmental Site Assessment (ESA) performed in 1996 revealed DRO above maximum allowable cleanup (MAC) levels in the soil. Groundwater was not investigated at this time.

Impacted soil is present around the center of the east side of the building from the ASTs. Surface soil samples contained up to 1,060 mg/kg DRO. There is an estimated 22 cubic yards of contaminated soil on the site. A non-potable drinking water well, located on the east side of the property, extends to a depth of 220 ft. (#2) Lt 2, Blk 100(Fuel Dispenser) underground fuel lines to the Jet Fuel Dispenser. Impacted soil is present around the Jet Fuel dispenser.

(#3) Lt 2A, Blk 300(Jet Fuel ASTs) 10,000 gal. and a 5,000 gal. AST. Impacted soil is present within and outside bermed area. Surface soil samples contained up to 292 mg/kg DRO and 0.463 mg/kg benzene. There is an estimated 26 cubic yards of contaminated soil on the site. (#4) Lot 5C, Block 100(ADOT Airport Lease Lot Building) 1,000 gallon Diesel AST. The AST is a likely source of contamination with up to 17,000 mg/kg DRO in the surface soil.
