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. 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. The Arctic Village School Standby Gen. site (Hazard ID 4021) is associated with a spill reported on March 28, 2003 after the generator building burned down. The generator building is located within the Arctic Village School site and the cleanup is being tracked with this site.

6/18/2021	Update or Other Action	ADEC staff met with site consultant to discuss the site closure pathway, focusing on details for sampling the landfarm. A multi-incremental sampling method was discussed to collect samples from across the landfarm on a grid at up to four depths between 0 and 24 inches to provide a statistically representative mean concentration of diesel range organics remaining in the landfarm.	Shawn Tisdell
9/7/2021	Site Characterization Workplan Approved	Incremental Sampling Methodology(ISM)workplan approved. Sampling is scheduled towards the end of September, 2021. The main objective for the sampling event will be to collect landfarm soil samples using an incremental sampling methodology (ISM) and analyze the samples for DRO. This sampling method was chosen as it provides reliable and defensible sampling data that is representative of DRO in the landfarm. DRO is the primary contaminant of concern remaining at this site. Ten additional discrete samples will also be collected to allow comparisons of DRO concentrations to past sampling events. Synthetic precipitate leaching procedure sampling (SPLP) will be conducted on a couple of samples to gain information on leachate potential from the landfarm soil and will help plan for a more comprehensive SPLP closure sampling event.	Shawn Tisdell
8/16/2022	Document, Report, or Work plan Review - other	Received 2021 Annual Landfarm Operations Report, dated April 21, 2022. Headspace field screening samples were collected from 134 locations, with results ranging from 0.2ppm to 638 ppm with higher concentrations in the lower part of the landfarm. The average PID results are significantly lower than previous years, with 90% of the results below 100 ppm. Discrete lab samples were collected from 10 locations that had the highest screening results. Diesel range organics ranged from 240 mg/kg to 12,200 mg/kg, which is lower than observed previously. Incremental sampling methodology (ISM) was also conducted and indicates that the true mean concentration of DRO remaining in the soil is below the project cleanup level established for the school of 4,000 mg/kg DRO and is no more than 2160 mg/kg with a 95% confidence. The consultant recommends preparation of a landfarm closure sampling workplan to address remaining data gaps with the goal of completing closure in 2023.	Shawn Tisdell
8/22/2022	Document, Report, or Work plan Review - other	ADEC received the Landfarm Closure Sampling Plan dated August 8, 2022. This sampling plan includes Incremental Sampling method testing of the interim cap placed over the landfill prior to placement of the landfarmed soil. Surface water sampling of the nearest pond located 520 feet downslope of the landfill, and documentation of results.	Shawn Tisdell
10/21/2022	Update or Other Action	DEC received an email from the consultant indicating that multi-incremental sampling was conducted this fall on the 12-inch interim cover layer beneath the landfarmed soil on the eastern half of the landfarm. This half of the landfarm has historically reported higher concentrations of contamination than the western half of the landfarm. Samples were also collected for leaching studies as requested by the DEC Solid Waste program. The site was bladed for closure in understanding that no further work will be required if the data supports that conclusion. A 2022 Landfarm Operating Report will be prepared after the lab results are released.	Shawn Tisdell

Nortech Inc. completed a "Pre-Demolition and Site Corrective Action Schematic Design and Cost Estimate" report. During this study, lead was evaluated with an XRF in 22 soil samples collected from the drip line around the elementary school and the propane storage building. Lead was found up to 1,329.6 mg/kg with the XRF, but Nortech indicated the lead was not hazardous based on averaged results. DRO in soil was found at concentrations up to 12,000 mg/kg in an area extending from the new bulk fuel storage west to the elementary school and north to an area beneath the water storage building and south to the barrel storage area. The report discusses an approach to demolish and dispose of hazardous and non-hazardous waste during building demolition activates, excavated and thermally remediate contaminated soils, and cap any remaining soil contamination.

Brownfields Award

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]

ADEC received the Nortech Arctic Village School Demolition and Site Remediation Plan. According to the plan, the action cleanup level for DRO in the top two feet of soil is 200 mg/kg and for soil greater than 2 feet below ground surface 4,000 mg/kg. 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.

DEC approved waiver of the post-closure requirements in 18 AAC 60.396 for the old Arctic Village landfill, which will be used as the location of the Arctic Village School landfarm. 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. Post-closure monitoring will be required for 5 years following approval by the DEC Contaminated Sites Program for landfarm closure. The post-closure monitoring is expected to be completed by the native Village of Venetie Tribal Government.

SERRC submitted Dump Site Interim Closure Report prepared by Nortech and dated March 30, 2018. The dump site is located 2.8 miles west of Arctic Village and covered approximately 4 acres. An 8.5 acre lot surrounding the dump site is being leased by the Yukon Flats School District for landfarming petroleum contaminated soil from the Arctic Village School soil excavation conducted in 2017. To prepare the site for landfarming, the contractors consolidated the solid waste and graded the area to eliminate steep slopes. An interim cover of 12 inches of clean gravel was spread over the site to close out the dump site, and petroleum contaminated material was spread 24 inches deep over the gravel. The village has agreed to maintaining the 5-year post closure care for the landfill by following monitoring requirements of 18 AAC 60.396.

ADEC staff met with site consultant to discuss the site closure pathway, focusing on details for sampling the landfarm. A multi-incremental sampling method was discussed to collect samples from across the landfarm on a grid at up to four depths between 0 and 24 inches to provide a statistically representative mean concentration of diesel range organics remaining in the landfarm.

Shawn Tisdell

9/7/2021

Site Characterization Workplan Approved

Incremental Sampling Methodology(ISM)workplan approved. Sampling is scheduled towards the end of September, 2021. The main objective for the sampling event will be to collect landfarm soil samples using an incremental sampling methodology (ISM) and analyze the samples for DRO. This sampling method was chosen as it provides reliable and defensible sampling data that is representative of DRO in the landfarm. DRO is the primary contaminant of concern remaining at this site. Ten additional discrete samples will also be collected to allow comparisons of DRO concentrations to past sampling events. Synthetic precipitate leaching procedure sampling (SPLP) will be conducted on a couple of samples to gain information on leachate potential from the landfarm soil and will help plan for a more comprehensive SPLP closure sampling event.

Document, Report, or Work plan Review - other

Received 2021 Annual Landfarm Operations Report, dated April 21, 2022. Headspace field screening samples were collected from 134 locations, with results ranging from 0.2ppm to 638 ppm with higher concentrations in the lower part of the landfarm. The average PID results are significantly lower than previous years, with 90% of the results below 100 ppm. Discrete lab samples were collected from 10 locations that had the highest screening results. Diesel range organics ranged from 240 mg/kg to 12,200 mg/kg, which is lower than observed previously. Incremental sampling methodology (ISM) was also conducted and indicates that the true mean concentration of DRO remaining in the soil is below the project cleanup level established for the school of 4,000 mg/kg DRO and is no more than 2160 mg/kg with a 95% confidence. The consultant recommends preparation of a landfarm closure sampling workplan to address remaining data gaps with the goal of completing closure in 2023.

Shawn Tisdell

8/22/2022

Document, Report, or Work plan Review - other

ADEC received the Landfarm Closure Sampling Plan dated August 8, 2022. This sampling plan includes Incremental Sampling method testing of the interim cap placed over the landfill prior to placement of the landfarmed soil. Surface water sampling of the nearest pond located 520 feet downslope of the landfill, and documentation of results.

Shawn Tisdell

10/21/2022

Update or Other Action

DEC received an email from the consultant indicating that multi-incremental sampling was conducted this fall on the 12-inch interim cover layer beneath the landfarmed soil on the eastern half of the landfarm. This half of the landfarm has historically reported higher concentrations of contamination than the western half of the landfarm. Samples were also collected for leaching studies as requested by the DEC Solid Waste program. The site was bladed for closure in understanding that no further work will be required if the data supports that conclusion. A 2022 Landfarm Operating Report will be prepared after the lab results are released.
