Problems/Comments

ADEC inspection on 7/22/1994 noted the following old Bureau of Indian Affairs (BIA) tank farm in poor shape. Free product pooled around tank farm. Many fittings actively leaking. Area is lined and diked, but integrity of liner unknown. Vertical extent of contamination unknown. Water well is 370 feet away. Strong fumes around school. Perhaps 800 square feet of impacted surface area noted. Village concerned about contamination problem. City contact is Sally Simmon at 968-2241. ADEC will ask Yukon/Koyukuk School District (YKSD) to perform site assessment. School district representative was supposed to repair loose fittings. The Allakaket Traditional Council applied to DEC for a DEC Brownfield Assessment (DBA) during the 2008 DBA request period. A brownfield file number was assigned to track work done under the brownfield program, 800.57.003. DEC is coordinating with the Environmental Protection Agency (EPA), which will conduct a Targeted Brownfield Assessment of other sites in the community, including the former diesel tank farm, gasoline tank farm, Alaska Power and Telephone Company (AP&T) generator building, and the pipeline that connects these various facilities.

Action Information

Action Date Action Description DEC Staff
8/2/1994 Site Added to Database Allakaket School. File # 800.38.001 by Thomas. Ben Thomas
9/11/1994 Interim Removal Action Approved Mehrdad reported 400 gallons of fuel removed from ditch next to the school tank farm contaminated dike and another 35 gallons from the ditch. Mehrdad Nadem
8/16/1996 Site Ranked Using the AHRM Ranked by Shannon and Wilson. NOTES: GW and SW Exposures and Surface Water Usages unknown. Communication with the village council may provide information for assigning a value for SW Usage. According to Stan Read of ADEC, a new tank farm area is being constructed and the former tank farm area was pretty well cleaned up prior to flood. A site visit should be conducted and sampling performed to determine the current status of the site. S&W
1/27/2004 Update or Other Action CIP Funding allocated for site. Site information being reviewed for RFP to assess old and new tank farm sites. Old tank farm (located 300' away from school) inundated by 1994 flood and new tank farm was constructed in 1996 next to school. Old tank farm capacity was approximately 34K gallons, new tank farm capacity is approximately 10K. Mike Jaynes
2/9/2004 Update or Other Action CIP RFP Forwarded on for approval. Mike Jaynes
2/12/2004 Meeting or Teleconference Held Pre-Proposal teleconference with prospective bidder. Discussed: TOC Sampling - 8 TOC samples from the area near the tank farms in uncontaminated soil. Collect the TOC samples from soil profile zones similar to the corresponding contaminated areas at the tank farms. With tank farms only 300 feet apart, soil profiles to be similar enough that can collect one batch of samples rather than two sets at each tank farm. PAH Sampling - we only need to document PAHs at the 3 highest areas of contamination at each site to get a baseline on worst case PAH levels. GRO+BTEX - take one to two samples to document each tank farm, then add samples as field screening warrants (PID gets high hits, etc.). Metals - instead of the RCRA8 specified in the RFP, collect one or two lead samples, as that's the metal of concern with fuel. Use professional judgement to modify these samples as warranted by field conditions. Mike Jaynes
2/24/2004 Update or Other Action Negotiated and accepted bid forwarded on for Notice to Proceed approval. Mike Jaynes
4/27/2004 Update or Other Action Project management assigned to Dave Pikul to work under the CIP Program. Mike Jaynes

10/7/2008 Brownfield Confirmed Notice to Proceed was issued on this date for DEC brownfield site assessment project at the Allakaket School. Area of focus is the former tank farm pad, located north of the school building. Other areas of concern will also be investigated at former generator building, current contained fuel storage tank area, and washeteria. Assessment intended to support Yukon Koyukuk School District efforts to install new drinking-water well on site as well as community's interest in constructing a new playground on the school property. Sonja Benson
12/17/2008 Meeting or Teleconference Held A stakeholder scoping and planning meeting was held to discuss plans for the upcoming DEC Brownfield Assessment at the Allakaket School. Participating on the call were the Allakaket School principal, tribal administrator, a tribal council member, and the tribal environmental coordinator, as well as representatives from DEC's Reuse and Redevelopment Program, the Alaska Department of Education and Early Development, and the DEC and EPA contractors working on the joint Allakaket assessment projects. The intent of hte meeting was to share background information and community concerns and to identify contractor logistical support and equipment availability in Allakaket. Sonja Benson
4/20/2009 Site Characterization Workplan Approved Comments sent to consultant on this date for minor revisions to the work plan. Sonja Benson
5/6/2009 Meeting or Teleconference Held A meeting to discuss the Allakaket School DEC Brownfield Assessment project, the school district's plans to install a new drinking-water well near the school, and two other school-related projects was held on this date at DEC offices in Fairbanks. Participants included representatives of the Yukon Koyukuk School District (YKSD) and DEC's Contaminated Sites (Reuse and Redevelopment) and Drinking Water Programs. Notes from the meeting were shared with the Alaska Department of Education and Early Development. Sonja Benson
6/17/2009 Site Visit Contractor field crew conducted site assessment June 17-19 in conjunction with assessment project at Allakaket airport. Using local equipment and labor, they excavated 20 test pits at four areas of concern around the school property, including the former YKSD tank farm, an area north of the former washeteria building, the current YKSD tank farm enclosure, and an area north of the former generator building. The soil in the test pits was made up of sandy gravel, sand, silty sand, sandy silt, and silt. Groundwater was not encountered in any of the test pits. Soil from the test pits was screened on-site. Samples were selected from the test pits on the basis of screening results for laboratory analysis of diesel-range organics (DRO), residual-range organics (RRO), gasoline-range organics (GRO), and benzene, toluene, ethylbenzene, and xylenes (BTEX). Excavating the test pits was more time consuming than anticipated, and complete characterization of the site was not accomplished. Petroleum hydrocarbon impacts were identified at the former YKSD tank farm containment and the area north of the former washeteria building. No impacts were noted around the current YKSD tank farm or the former generator building. Sonja Benson
12/21/2009 Report or Workplan Review - Other Site characterization report received from DEC term contractor, will be made final pending review and comment by DEC. Sonja Benson
3/19/2010 Site Characterization Report Approved Site characterization identified DRO contamination in soil above DEC migration-to-groundwater cleanup levels at the school's former tank farm pad and at the former washeteria building. In BTEX analysis some detection limits were above MTG cleanup levels so it is undetermined whether BTEX may exceed MTG levels. PAH compounds identified at both locations were 1- and 2-Methylnaphthalene. Characterization was not completed at all areas of concern because of time constraints and unanticipated underground utilities. Remaining assessment is intended to coincide with recommended remedial action and confirmation sampling. Sonja Benson

3/11/2011 Report or Workplan Review - Other DEC received the final Allakaket Targeted Brownfields Assessment Report dated February 5, 2011. During the assessment soil samples were collected from areas all over the village. One of the discretionary samples (DS-02)collected during the site visit was collected from the Former YKSD Tank Farm area. The soil sample was analyzed for GRO, DRO, RRO and BTEX and all the samples results were below DEC cleanup levels. Deborah Williams
8/5/2015 Update or Other Action Briefing from former PM. Site transferred to Whitsel for evaluation of BIA as PRP, other PRP identification and follow up. Fred Vreeman
7/27/2017 Update or Other Action Discussed with Tanana Chiefs Conference Brownfield Technician the next steps availability to the community to move toward cleanup. The 2010 Brownfield assessment is still valid and should be used as a guide in developing remediation priorities Joy Whitsel
