6/29/2004	Update or Other Action	Received HartCrowser report "Soil Removal Report; Stevens Village Old School Site." 1,500 cubic yards of soil and three ASTs were removed. Two soil stockpile cells were constructed to contain diesel and gasoline contaminated soils. Soil analytical samples from the limits of excavation showe DRO levels up to 25,300 mg/kg 6 feet bgs. Underneath the Former Maintenance Room benzene was detected above ADEC cleanup levels (0.138 mg/kg). Added to the database in 2007 to reflect administrative file.	Shannon Oelkers
2/6/2007	Exposure Tracking Model Ranking	Ranked site using ETM model.	Shannon Oelkers
2/14/2007	Update or Other Action	Confirmed with City of Stevens Village that clinic has not been built. Funding is secured, but village has not passed their RUBA assessment. No building on site. Pikul reports that building plans for clinic included refridgerated piers and no skirting. Indoor air unlikely to be affected by vapor intrusion.	Shannon Oelkers
2/19/2007	Update or Other Action	DEC met with the term contractor awarded the RFP for additional site work to discuss tasks, and determined that soil sample collection from the soil stock pile generated in 2004 is not warranted. The soil was placed adjacent to the landfill for the purposed beneficial reuse as landfill cover. Excavation samples will be used to consider an average soil concentration in the stockpiled soil. In-door air vapor intrusion modeling will not be conducted based on the lack of volatile contaminants at the site and understanding that any structure erected will be built on pilings (refrigerated) to protect against damage during flooding of the Yukon River and structure subsidence due to permafrost thawing. It was further determined that no monitoring wells should be installed due to the sites position in the floodplain of the Yukon River, the relative shallow depth to groundwater, existence of permafrost at 5 to 8 feet below the ground surface and the propensity for any permanent wells to be damaged during seasonal freezing and thawing. A “snap-shot” groundwater investigation is proposed by DEC and costs will be submitted from the term contractor for both groundwater sample collection using mirco-rig technology and manual hand hammer techniques. Because the highest likelihood to encounter free subsurface interstitial water is following the longest thawing period, August 2007 was selected for implementation of the release investigation. A CSM will be completed during this phase of site work	David Pikul
7/3/2007	Site Characterization Workplan Approved	Reviewed Stevens Village Old School Workplan from SLR. Suggested minor changes to the stockpile sampling plan and to the contents of the final report. Site work is scheduled for early August 2007.	Shannon Oelkers
7/27/2007	Update or Other Action	Site transferred from Oelkers to Frechione.	Shannon Oelkers
11/23/2007	Site Characterization Report Approved	SLR assessed groundwater conditions and the soil stockpile in August 2007. Groundwater was not encountered on site (above permafrost level) but four temporary well points sampled ground -surface water interface along Yukon River. No contamination above cleanup levels was detected in water samples. The soil stockpile (approximately 1400 cubic yards) located at the community landfill was sampled. The 10 samples detected elevated levels of contamination above migration to groundwater levels (7 of 10 samples) and inhalation levels (2 of 10 samples).	Jim Frechione
2/6/2008	Conditional Closure Approved	DEC recognized that the tanks and contaminated soil were removed from the site. there was residual soil contamination remaining on site because it could not be excavated without compromising the road or because permafrost prevented further removal. No further action is required and the site was closed subject to the owner / operator of the property coordinate with DEC for any future soil excavation. Also - the soil that was transported off site to the landfill is stored there until treatment or disposal options are approved	Jim Frechione
2/6/2008	Institutional Control Record Established	the closure document is subject to: 1. The owner/operator of this site shall not excavate or transport soil off site without prior notification to ADEC. In the event soil excavation is proposed, ADEC shall be contacted to determine if a qualified environmental contractor may be required to provide environmental oversight in accordance with 18 AAC 75 regulations. 2. A Notice of Environmental Contamination will be posted on the ADEC database to identify issues and/or conditions associated with the residual contamination remaining on site. This notice should also be attached to any conveyance deed or document when (or if) the property is conveyed to another party.	Jim Frechione
1/6/2010	Institutional Control Record Removed	At the request of the project manager, Tamara Cardona-Marek, the institutional controls are removed from this site. The site conditions meet the updated closure policy.	Evonne Reese
5/4/2011	Site Reopened	This site is reopened and will briefly be considered Active until the Cleanup Complete - ICs can be re-applied as the status. In 2010 the ICs were removed in error and should have remained attached to the site.	Evonne Reese
5/4/2011	Cleanup Complete Determination Issued	This in an adminstrative action that is being used to correct an error that was made in 2010 when ICs were removed.	Evonne Reese
5/4/2011	Institutional Control Compliance Review	IC review conducted, staff changed to IC unit, and reminder system initialized.	Evonne Reese
2/8/2012	Update or Other Action	During the cleanup efforts at this site, contaminated soil was taken to and stored at the village dump. Due to pending efforts to close the dump and develop a new permitted landfill for Stevens Village at a different loction, DEC determined that further remediation of these soils may be necessary. Using CIP funding, DEC has contracted with Shannon & Wilson to sample the soil stockpile in the summer of 2012 to determine the remaining concentrations present in the soil. The stockpile was entered as a source area, and work assocaited with the stockpile will be tracked under the school site.	Janice Wiegers
7/30/2012	Document, Report, or Work plan Review - other	Received sampling report for soil stockpiles totaling 1500cy near the Steven's Village Landfill. Samples collected from the stockpiles were analyzed for GRO, DRO, RRO, BTEX, and PAHs. Contamination in stockpiles exceeded the migration to groundwater cleanup levels for DRO but were below all other cleanup levels. The stockpiles appear overgrown with foliage in the report photos. (MHooper 2018.05.30)	Willett Boger
7/24/2013	Update or Other Action	Contacted Tutka (on site contractor) and WH Pacific (contractor for USDA landfill project)to determine the final disposition of the old landfill closure and cover material used. During closure of the old landfill the contaminated soils had been proposed for use as cover material, however this did not occur and the stockpiles remain in their original location near the old dump. (edited MHooper 2018.05.30)	Willett Boger
10/7/2013	Update or Other Action	Site symbol visually adjusted using ArcGIS and documents from the file. 66.006281, -149.095345. 10/7/13; MLB.	Michelle Barnes
9/2/2016	Institutional Control Compliance Review	Staff changed from Will Boger to IC Unit. IC compliance review conducted. Scheduled to send a reminder letter in the near future.	Kristin Thompson
5/30/2018	Update or Other Action	Reviewed file and spoke with solid waste staff. The stockpile is still in the same location it has been since 2004 next to the old landfill location. The contaminated soils tested at above migration to groundwater for DRO in 2012. The stockpiles are overgrown with foliage and are on top of a liner that is in questionable condition.	Michael Hooper
2/17/2021	Institutional Control Compliance Review	IC compliance review. Contact with the current landowner is done every five years so is scheduled for May 2022.	Evonne Reese
3/18/2024	Institutional Control Update	DNR-SAIL added as affiliate (Office of Primary Responsibility). For DNR LAS information: ADL# 420163	Jennifer McGrath
