Problems/Comments
The AST farm is located behind the former high school, which is now the Kokarmiut Corp. Building, approximately 700 feet from the Kuskokwim River. There is a 2-foot-high gravel dike and liner around the AST farm. Vegetation is growing inside the dike. The facility is not fenced or gated. The tank farm consists of seven vertical, welded steel, single wall, BIA-style tanks with removable tops. The individual ASTs vary in capacity from 5,000 to 9,750 gallons, with a total tank farm capacity of 54,000 gallons. The ASTs are supported on 12-by-12-inch timbers with 2-by-14-inch planking. The timbers and planking supporting the ASTs rest upon a sandbag substrate. Stained and darkened soil and sandbags were noted throughout the berm area. One soil sample was collected at 12 inches bgs, adjacent to the gasoline fuel dispensing pump on the west side of the AST farm. GRO concentration was 9,100 mg/kg and DRO concentration was 4,300 mg/kg. file number has been changed from 2402.42.001 to 2402.38.001
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 1/3/2001 | Document, Report, or Work plan Review - other | On this date, ADEC received Akiak AST Tank Farm Site Reconnaissance, dated December 2000, submitted by Eco. & Envi, Inc. | Grant Lidren |
| 4/16/2003 | Site Added to Database | GRO and DRO contamination. | Deborah Williams |
| 4/16/2003 | Site Ranked Using the AHRM | Preliminary ranking. | Deborah Williams |
| 3/2/2004 | Update or Other Action | Site inventoried through TAPL funded site recon. With loss of TAPL funding to Alaska Energy Authority, future assessment and remediation cannot be funded. Looking for additional funding sources, possibly CIP. | Mike Jaynes |
| 11/29/2006 | Update or Other Action | Staff transferred from Pikul to Jaynes. | Aggie Blandford |
| 9/28/2009 | Site Visit | An initial site visit, performed by SLR, was completed on September 28 & 29 2009 before site work scheduled for the week of October 26, 2009. Two tanks are currently in use supplying the nearby teacher housing. The only known drinking water well was located 500 feet away from the tank farm. Eight tanks were discovered at the site (5 upright and 3 toppled over) inside an unlocked, fenced, lined area. Sheen was noted at three locations inside the containment area. | Grant Lidren |
| 10/13/2009 | Document, Report, or Work plan Review - other | ADEC approved the Akiak Combined TF Site Characterization Work Plan Akiak Alaska submitted by SLR. Site work is scheduled for the week of October 26, 2009. | Grant Lidren |
| 2/19/2010 | Document, Report, or Work plan Review - other | ADEC reviewed Old High School Tank Farm Site Characterization Report, dated February 8, 2010, submitted by SLR. Eighteen soil samples were collected from 15 soil borings and one test pit located around the tank farm. Test pits were not advanced north, east, or west of the tank farm due to obstructions. Soil samples from boring 10 and 13, located south of the tank farm, collected at a depth of 0.5 to 5.0 ft. bgs, contained GRO up to 3,870 mg/kg, DRO up to 2,690 mg/kg, benzene up to 0.501 mg/kg, toluene up to 12.5 mg/kg, ethylbenzene up to 8.5 mg/kg, total xylenes up to 156.4 mg/kg and PAHs 1-methylnapthalene and 1-methylnapthalene up to 12.3 mg/kg and 18.3 mg/kg respectfully. An estimated 69 cubic yards of petroleum impacted soil is located at this location. The rest of the soil borings contained detectable levels of contaminants, but below cleanup levels (note: the PQLs for some of the VOC samples were elevated due to matrix interference, therefore these samples could be over cleanup levels). Groundwater was not encountered at 12 ft. bgs, consequently drive point wells were not installed. The closest drinking water well is located 500 ft away from the tank farm. | Grant Lidren |
| 5/10/2013 | Site Visit | The Solid Waste Program performed a site visit during the week of May 6th. Brand new fence installed around the tanks with the gate locked – no access for the public. Some of the tanks have fallen over. Lots of vegetation growing on berm with ice inside it. Since the land has been given to the City by the school district, the City just realized they are responsible for these tanks. They are trying to figure out what to do about them. | Grant Lidren |
| 5/27/2015 | Update or Other Action | Transfer from Anchorage to Fairbanks 5/27/15 | Susan Carberry |
| 4/26/2016 | Update or Other Action | Site assigned to Joy Whitsel for identification of PRPs, evaluation of cleanup progress, and follow up. | Fred Vreeman |
| 6/28/2019 | Update or Other Action | Letter provided to BIA providing a list of 31 sites where BIA is a PRP and requesting a meeting to discuss long-term planning for cleanup at these sites. | Gretchen Caudill |
| 4/25/2025 | Site Characterization Workplan Approved | DEC has reviewed and approved the "Site Characterization Work Plan" for the Akiak Elementary School Former Tank Farm and the Akiak High School Former Tank Farm sites. This work plan details the continuation of site investigation activities planned for the 2025 field season. Soil borings will be advanced to delineated contamination detected during the 2009 site investigation and to characterize the horizontal and vertical extents of contamination. Paint chip samples will be collected from both tank farms to evaluate if lead or PCB based paints were used. | Kelly Walker |
