Site Report: ADOT&PF SREB - Buckland AST

Site Name: ADOT&PF SREB - Buckland AST
Address: Buckland Airport, Buckland, AK 99727
File Number: 520.38.007
Hazard ID: 25361
Status: Active
Staff: Erin Gleason, 9072697556
Latitude: 65.980467
Longitude: -161.138128
Horizontal Datum:WGS84

We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


The facility consists of one, unfenced, 2,700-gallon aboveground storage tank (AST) that was installed on a gravel pad north of the Snow Removal Equipment Building (SREB) in 1997. The tank is a double-walled, horizontal, skid-mounted, welded steel, dike tank. A total of two soil samples were collected. One soil sample, collected to the west of the AST, at 1 foot below ground surface (bgs), contained 1,380 milligrams per kilogram (mg/kg) diesel range organics (DRO). The second soil sample, collected on the North side of the AST, at 1 foot bgs, contained 1,960 mg/kg DRO. Gasoline Range Organics (GRO), ethylbenzene, and xylenes were also detected below cleanup levels. PID screening indicates the areas of greatest contamination are North and West of the AST. Contamination is probably the result of spills during routine refilling and dispensing into vehicles. See also Hazard ID 4039 (file number 520.38.001) for additional source areas at this site. The second source area (520.38.001) covers historic contamination WITHIN the SREB. During summer 2018, local contacts reported that the contamination was from children playing on the fuel lines like a jungle gym, until the fuel lines broke, releasing fuel onto the ground adjacent to the building.

Action Information

Action Date Action Description DEC Staff
9/26/2001 Update or Other Action Shannon & Wilson conducted a site reconnaissance on 26 Sep 2001 as part of a Denali Commission assessment. The AST is a double-walled, horizontal, skid-mounted, welded steel, dike tank that appeared to be in good condition. The facility operator (Mr. Ernie Thomas) was unaware of any releases or problems associated with the AST. No surface stains were evident, and no active leaks were observed. However, PID field screening measurements ranged from <1 to 150 ppm around the tank. Soil on the west side of the AST contained up to 1,380 mg/KG DRO, 46.5 mg/Kg GRO, <0.0175 mg/Kg benzene, <0.0699 mg/Kg toluene, 0.124 mg/Kg ethylbenzene, and 0.277 mg.Kg total xylenes at 1' BGS. Soil north of the AST contained 1,960 mg/Kg DRO, 107 mg/Kg GRO, <0.0186 mg/Kg benzene, <0.0745 mg/Kg toluene, 0.408 mg/Kg ethylbenzene, and 0.661 mg/Kg total xylenes. Contamination is likely a result of overfilling or spills during filling or vehicle fueling. Richard Bernhardt
1/25/2008 Update or Other Action Provided copy of Shannon & Wilson AST Recon Assessment report to Mayor Ticket of Buckland who was in our offices to meet with VSW regarding a capital improvement project in Buckland. Keather McLoone
1/25/2008 Site Added to Database A new site has been added to the database (Date adjusted from 2/25/2009 for report/query consistency. (Reese)) Mitzi Read
3/3/2008 Update or Other Action Met with Jon Menough of VSW program regarding upcoming work in Buckland. He confirmed that the water intake for the village is currently upstream from the village and that "Plan A" has it again going in upstream although an alternative plan would place it in a downstream location and he is now informed of the potential concerns regarding such a placement. The construction project will have DEC and construction oversight staff in the village very often over ~ next 3 years. Keather McLoone
2/25/2009 Exposure Tracking Model Ranking Initial ranking with ETM completed for source area id: 78717 name: 2,700-gallon AST Mitzi Read
1/14/2010 Update or Other Action Reconfirmed with Debra Addie on 1/14/2010 about location of water intake location as the drinking water program maps/tools have it an incorrect location downgradient. Keather McLoone
3/13/2012 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 78717 2,700-gallon AST. Keather McLoone
1/7/2013 Meeting or Teleconference Held Spoke with ADOT&PF (Sam Myers) to promote additional characterization and potentially even remediation at this site in 2013. Mr. Myers is receptive, so we'll work together over the coming months to formalize a plan. Richard Bernhardt
1/8/2013 Update or Other Action Spoke with Clarence Thomas (Public Water Administrator) at the Buckland City Office (494-2121) and learned that Buckland get its water from the Buckland River, and their public water intake is located at 655829.3N 1610732.1W (Coords obtained from Google Earth during discussion with Mr. Thomas). This intake is upstream from all known or suspected contaminated sites in Buckland. Richard Bernhardt
1/9/2013 Meeting or Teleconference Held Spoke with Mr. Sam Myers (ADOT&PF) again to discuss the type of information that ADEC will need in order to progress toward site closure. Three surface soil samples surrounding the AST, and subsurface soil samples (as needed based on field screening) should allow characterization, but a groundwater sample may become necessary, if there are indications of subsurface soil contamination at depth and if the pad is saturated. Additional characterization may or may not become necessary based on results of initial sampling event. Richard Bernhardt

6/5/2018 Meeting or Teleconference Held Meeting with ADEC, ADOT construction, ADOT environmental, ADOT Statewide environmental, and Nortech to discuss work plan revisions and site management. Erin Gleason
6/13/2018 Update or Other Action Received revised work plan from ADOT Erin Gleason
7/6/2018 Site Characterization Workplan Approved Received final revised report from ADOT. Work plan is now approved. Erin Gleason
8/28/2018 Update or Other Action ADEC has approved the transport and disposal of 60 cubic yards of contaminated soil to the Buckland landfill pending acceptance by the ADEC solid waste program and the landfill operator. Erin Gleason
11/20/2018 Site Characterization Report Approved Received characterization report from ADOT on 10/3/2018, that includes work conducted in summer 2019. ADEC has reviewed the report and it is now approved. 60 cubic yards of petroleum contaminated soil was excavated from the north side of the SREB and disposed of in the Buckland landfill. Field screening measurements and analytical samples were collected from the sidewalls and base of the excavation. Samples were below ADEC cleanup levels for all contaminants of concern (COC). A stain was observed on the west side of the SREB beneath the skid mounted AST fill line and appeared to extend ~2 feet deep and underneath the tank. The portion of the stain that was not under the tank was removed with hand tools. A single PID reading was taken from the stain area and measured 15,000 ppm. Nine post holes were dug around the north side of the SREB as part of a security fence installation. All post holes were field screened with a PID. An analytical soil samples was collected at the post hole with the highest field screening. PH7 had a DRO concentration of 423 mg/kg, which exceeds migration to groundwater cleanup levels.
