Problems/Comments

School Tank farm has history of diesel spills, leaking pipes and overfills appear to be typical causes. Many of these spills are due to poor housekeeping and handling practices. Also waste oil spill and broken batteries evidenced. A majority of the contamination at the school tank farm was caused by a small hole in Tank 5 and minor spills and leaks from the fuel lines. Other impacts were identified in and around the School Generator Bldg and the day tank and used oil storage area. DRO and GRO contamination. Approximately 600 cubic yards of estimated impacted soil. This was to be addressed by TAPL Program. West in Arctic National Wildlife Refuge, along East Fork of the Chandalar River. (FY93) (rpltr9) The spill that occurred at the school garage building was transferred from PERP. (Spill #95309921901, 500 gallons of diesel spill on 8/7/95.) A Targeted Brownfield Assessment (TBA) of the Arctic Village School was completed in 2005 and provided to DEC in 2006. The site visit for the TBA occurred in 2004. A separate brownfield file, no. 740.57.001, was set up to track on this work and it contains a copy of the TBA report.

6/5/2006 Brownfield Confirmed DEC's Contaminated Sites Program office in Fairbanks received a copy of the Targeted Brownfield Assessment (TBA) for the Arctic Village School on this date. The date of the report is May 2005. Field activities for this project were done in conjunction with work by NORTECH Environmental, which was performing a predemolition building survey and site inspection for hazardous materials. Areas considered for investigation were based on information provided in the Native Village of Venetie Tribal Government's proposal for the TBA and a work plan developed by the Yukon Flats School District through NORTECH. Results of subsurface soil sampling indicated widespread DRO and GRO contamination, with the highest concentrations located between the elementary school and preschool (3,240 mg/kg to 22,200 mg/kg), the area surrounding the former generator building (613 mg/kg to 29,500 mg/kg), and around the active tank farm (480 mg/kg to 17,400 mg/kg). Lead contamination in soil was also noted, and was attributed to lead-based paint flaking off the elementary school building and the propane storage building. [see file 700.57.001] Sonja Benson
7/3/2006 Update or Other Action ADEC received the Nortech Arctic Village School Demolition and Site Remediation Plan.

The excavation will be backfilled with a minimum of 2 feet of clean silty soil in order to promote permafrost freeze back. Once the project is awarded to a contractor, they will submit a work plan to the Department for approval for the treatment and disposal of the contaminated soil. Deborah Williams

As part of the landfill closure, an interim 12-inch cover will be added to the landfill prior to landfarm construction. Once landfarming is complete, the remediated soil and clean material from the surrounding berms will be used for the final landfill cover material. For permanaent closure, the landfill must have a 36 inch cover, graded to promote proper drainage, and revegetated.
