10/3/2005 Site Characterization Report Approved Staff sent an approval letter on the ROST/LIF investigation. The report describes an investigation to identify and delineate potential fuel contamination at the Northway Alaska Communication System (ACS) Formerly Used Defense Site located in Northway Junction. The data acquisition method utilized was the Rapid Optical Screening Tool and its laser-induced fluorescence (LIF) probe. Forty LIF probe pushes were completed at the site to delineate the vertical and horizontal extent of petroleum contamination at the ACS site. Completion of the LIF pushes identified the extent of the petroleum contamination near the power plant and on the eastern portion of the site, between the former pipeline and the road. Diesel range organics were identified close to the bedrock interface near the power plant and up to 19 feet below ground surface downhill from the former pipeline. This information will be used along with previously obtained soil data and the groundwater monitoring wells that are being installed this fall to prepare a feasibility study for the ACS site. The report fairly presents the information obtained from the investigation and meets the requirements of 18 AAC 75.355, Site Characterization and is approved. Debra Caillouet
10/5/2005 Site Characterization Workplan Approved staff sent an approval letter regarding the groundwater investigation work plan Debra Caillouet
2/8/2006 Update or Other Action Five new monitoring wells were placed through competent bedrock to characterize further the groundwater contamination at the Northway ACS. The results of groundwater sampling completed in October 2005 show diesel range organics (DRO) present in three of the new wells above 18 AAC 75.345 Table C Groundwater Cleanup Levels and residual range organics (RRO) above Table C levels in two of the wells. Benzene, toluene, ethylbenzene, and xylenes (BTEX) and polycyclic aromatic hydrocarbons (PAHs) were not detected above cleanup levels in the groundwater. The soil in each well boring was screened and the highest samples analyzed by a laboratory for DRO, RRO, BTEX and PAHs. The soil in one boring was above 18 AAC 75.341 Method 2 cleanup levels for DRO from 7 feet below ground surface (bgs) to 17 feet bgs. This boring was in the same area the Rapid Optical Screening Test/Laser Induced Florescence sampling in August 2005 identified soil contamination remaining. The other four borings did not contain contaminants above Method 2 levels. The discussion of the groundwater contamination states that the location of the groundwater contaminant plume and groundwater flow direction suggests that there may be multiple sources of contamination. DEC recommends that this be expanded to include the possibility that fractures in the bedrock may have transported contamination in directions not predicted by groundwater flow. The report recommends additional monitoring wells be placed to define the complete extent of groundwater contamination on the west and southwest sides of the site. A well is also recommended east of the site but the report acknowledges that due to the steep gradient this may not be possible. DEC concurs with this recommendation. The recommendation for the treatability study for the soil is to evaluate bioventing with and without augmentation. DEC concurs. The report indicates that the remedial alternatives that were proposed for the groundwater treatability study have been impacted negatively by the findings of this investigation and states that further evaluation will be presented in the Treatability Study Work Plan. DEC suggests that natural attenuation of the groundwater after source removal be included in the treatability study. Debra Caillouet
2/16/2006 Meeting or Teleconference Held Staff met with the Corps and their contractor to discuss the results of groundwater sampling at the Northway ACS and the plans for a treatability study this summer for both the soil and groundwater. A biovent study with and without supplemental nutrients will be done for the soil. It was decided that not enough information was known about the groundwater to make a treatability study practical and that sampling to determine the rate of natural attenuation would be the best use of resources. Potentially two additional downgradient wells will be installed to determine a clean point for the groundwater that is impacted by diesel range organics. The Corps is preparing a closure decision document for the CON/HTRW project . Debra Caillouet
2/28/2006 Update or Other Action The Draft Final Chemical Data Report, Northway Staging Field and Alaska Communication System, Summer 2005 was reviewed and a comment letter sent to the Corps. Debra Caillouet
5/3/2006 Update or Other Action A draft work plan for the Northway ACS Treatability Study was reviewed and comments sent to the U.S. Army Corps of Engineers. The treatability study will evaluate bioventing, with and without amendments, as a remedy for DRO contaminated soil located from the surface to 30 feet below ground surface. Additional monitoring wells will be installed through bedrock to determine the groundwater flow and size of the DRO plume that is associated with the DRO contaminated soil. Natural attenuation parameters will be analyzed to determine if it is occurring and the rate. Debra Caillouet
5/3/2006 Update or Other Action A draft work plan for additional site characterization and support of the bioventing feasibility study using the U.S. Army Corps of Engineers ROST at the Northway ACS was reviewed. The plan describes use of the ROST to determine relative contaminant levels before and after the treatability study to support laboratory analysis of soil samples. Debra Caillouet

5/29/2007 Update or Other Action The Final 2006 Soil Treatability Study Report, Northway Alaska Communication System Formerly Used Defense Site, Northway Junction, May 2007was reviewed and approved. The report documents the installation of a bioventing system to treat petroleum contaminated soils in-situ at the Northway Alaska Communication System (ACS) and the installation of a second system to treat soils from an excavation in the area of the former used oil sump in a stockpile. Radius of influence testing and respiration testing were performed for the in-situ system. The report recommends the addition of nitrogen and moisture to enhance the rate of bioremediation for the in-situ soil. Baseline samples were analyzed from the soil stockpile to document the beginning conditions. The ex-situ system will be started in 2007 along with the in-situ system. An amended work plan for the 2007 operations at the ACS is planned. The report also presents the results of the confirmation sampling from the excavation at the former used oil sump area. Five of eight confirmation samples exceeded the Method 2 cleanup level of 250 mg/kg diesel range organics. Three of these samples were obtained at the bedrock interface and two of the samples were obtained where the excavation was halted to prevent undermining the existing building. The contaminated soil was removed to the extent practicable until the existing building is removed from the site. The highest concentration detected next to the building was 4720 mg/kg DRO. Debra Caillouet
8/17/2007 Update or Other Action Staff reviewed and approved the final 2007 Treatability Study work plan Debra Caillouet

7/31/2008 Update or Other Action Staff reviewed the Draft Northway ACS Feasibility Study Report, Northway Alaska Communication System, Northway Junction. Alaska. The FS evaluates three alternatives for treating the soil and three alternatives for treating the groundwater at the site. Soil sampling has shown a maximum of 9700 mg/kg diesel range organics which is below the ingestion cleanup level of 10,250 mg/kg and the inhalation level of 12,500 mg/kg. It is above the migration to groundwater cleanup level of 250 mg/kg. Groundwater has been found to be contaminated with DRO at one drinking water well, along with several monitoring wells installed at the ACS. The soil treatment alternatives evaluated were excavation to bedrock and off-site treatment, excavation to 10 feet below ground surface and off-site treatment, and institutional controls (ICs) to prevent exposure to the contamination. DEC can support any of these alternatives. The groundwater treatment alternatives evaluated were to provide an alternative water supply for the home effected by the contaminated groundwater well and ICs provide a point of use treatment system for the home affected by the contaminated groundwater well and ICs, or ICs with monitored natural attenuation. DEC supports providing an alternative water supply for the home and institutional controls to prevent exposure to the contaminated groundwater along with monitored natural attenuation.

5/21/2019 Document, Report, or Work plan Review - other 2018 Groundwater Monitoring Report reviewed and comment letter submitted. Five monitoring wells and one drinking water well were evaluated, measured and sampled over 21-22 September 2018. Diesel range organics (DRO) were the only petroleum, oil, lubricant contaminant that was sampled that had concentrations above cleanup levels, in three wells. Manganese exceeded cleanup levels in two wells, presumed to be attributed to bioremediation. Three wells besides the five sampled could not be used due to presence of free product, dewatering, and heat trace malfunction, respectively. Continued monitoring is recommended on the three-year cycle. DEC provided the following general comments on the field effort and reporting: 1. Inoperable monitoring wells/heat trace should be repaired or replaced, as determined appropriate prior to the next sampling event. Because 2005-05C and 2006-01 could not be sampled, a trend analysis was unable to be completed in 2018. Thus, the objectives of the groundwater monitoring program were not fully met. Trend analysis will be needed for the next, and subsequent, monitoring events to properly characterize the progress of the remedy of monitoring and natural attenuation. 3. Given the extent of uncontrolled use by site visitors evident in the photolog, it seems that institutional control signage may be appropriate at this site to prevent excavation and warn of exposure to contaminated soil.

5/23/2019 Document, Report, or Work plan Review - other DEC reviewed and provided comments on the Draft 2018 Northway ACS site Periodic Review Kevin Fraley
12/30/2019 Document, Report, or Work plan Review - other DEC approved the 2018 Final Groundwater Sampling Report, Northway Alaska Communication System, dated November 2019. Five monitoring wells and one drinking water well were evaluated, measured and sampled over 21-22 September 2018. Diesel range organics were the only petroleum, oil, lubricant contaminant that was sampled that had concentrations above cleanup levels, in three wells. Manganese exceeded cleanup levels in two wells, presumed to be attributed to bioremediation. Three wells besides the five sampled could not be used due to presence of free product, dewatering, and heat trace malfunction, respectively. Continued monitoring is recommended on the three-year cycle. Kevin Fraley
3/4/2020 Document, Report, or Work plan Review - other DEC approved the 2018 Final Periodic Review, Northway Alaska Communication System, Formerly Used Defense Site Project Number F10AK017703, Northway, Alaska, dated January 2020. As part of the 2018 periodic review, a site inspection was conducted, the conceptual site model was evaluated, and protectiveness of the remedy was assessed. The site inspection indicated that trespass and land use change may be occurring, as evidenced by the presence of unknown drilling equipment, a recent excavation near the contaminated area, disturbance of surface soil by ATV use, and dumping and burning of debris. The new water supply well has been installed and the former water supply wells have been decommissioned. The conceptual site model evaluation indicated that the contaminants of concern, exposure pathways, and potential receptors were largely unchanged since the Decision Document was issued. The assessment of the protectiveness of the remedy stated that the remedy is functioning and is protective of human health and the environment. However, DEC is concerned about the land use change, excavation, and trespass that appears to have occurred at the site. DEC also notes that a deed notice documenting the contamination at the site and setting requirements for management of the contamination, required as part of the remedy, has not yet been implemented, despite more than five years having passed since the issuance of the Decision Document. Uniform Environmental Covenants Act (UECA) covenants must be filed for the site as soon as possible in order for the remedy to be fully implemented and for protectiveness to be assured. In correspondence with the U.S. Army Corps of Engineers (USACE), it was stated that the process to file UECA covenants for this site has been initiated. Thus, DEC approves this report, but USACE must submit a plan of action and deadline for filing the covenants. DEC has requested that USACE provide this plan and deadline within 30 days of this approval. Kevin Fraley
