Problems/Comments

This is the location of the former AVEC tank farm, which was moved to its new location near the airport in 1997. A vertical BIA style tank is currently situated at this site. The drain plugs at the base of this tank were removed and the tank was empty. The soil sample collected from the site contained 26,200 mg/kg DRO, however this result is considered biased high due to out-of-range surrogate recovery. A diesel odor was detected when test holes were made for sample collection in the northern area of the tank farm. The tanks were apparently located in an unlined containment basin constructed of a 2-3 foot high gravel dike topped with sandbags.

10/15/2007 Report or Workplan Review - Other Former AVEC Power Plant Anvik, Alaska Phase 1 Environmental Site Assessment dated October 2007, submitted by BGES and received by ADEC 9/08/2008. According to interviews in the report as well as from information on site ownership and use from the Anvik Brownfield Response Program, the property has had numerous releases of fuel oil from the tanks as well as from the pipeline that was used to fill the tanks. It is reported that a spill of 20,000 gallons of diesel occurred in 1991, from a tank that tipped during a flooding event. In addition, the rubber joints in the pipeline that was used to fuel the power plant and deliver fuel to other tanks in the village had numerous seeps and leaks. One instance indicates 200 gallons a year would leak out of the pipeline between AVEC, the old school and the City's tank farm. Leaks would also occur every time the barge refueled AVEC. One of the areas of the pipeline leaks was reportedly dealt with by installing a 55 gallon drum underneath the pipeline to catch dripping fuel. It was also reported that solvents and diesel fuel was used for cleaning activities on the property. Reportedly the solvents and fuels were allowed to flow through the drain to a 55 gallon drum, which was allowed to overfill numerous times. Transformers were also stored on the property. VOCs and PCBs presence needs further evaluation. Grant Lidren

8/31/2009 Report or Workplan Review - Other Reviewed QAPP submitted by Yukon River Intertribal Watershed Council on behalf of the Village of Anvik. This Brownfield-funded project will be investigating the presence of PCBs at the site and delineating the nature and extent of petroelum impacts. Bill O'Connell
12/14/2009 Report or Workplan Review - Other Reviewed the 2009 Phase II ESA at the AVEC former Tank Farm conducted by Yukon River Intertribal Watershed Council (YRITWC) under their Brownfield Program. PCBs were removed from the list of COCs by YRITWC based on documentation provided by AVEC showing that PCB-containing transformers were not used a the site. THirty six locations were field screened and 14 soil samples were collected from hand-augered boreholes that were advanced to a maximum depth of 8.5 feet bgs. Six soil samples contained DRO above the Method Two MTG cleanup level of 250 mg/kg ranging from 290 mg/kg to 81,000 mg/kg. GRO and BTEX were not analyzed. Contamination is suspected to be present, but was not delineated, at the property to the west Bill O'Connell
