(1) Samples will be collected as for the long-term monitoring program at the Airstrip, Powerhouse, and Bulk Fuel Tank Farm sites. As needed, any unusable monitoring wells will be replaced. Samples will include active zone groundwater samples at all three sites, surface water samples from Imikpuk Lake adjacent to the Powerhouse and Airstrip Sites, and surface water and sediment samples in the North Salt Lagoon adjacent to the Bulk Fuel Tank Farm site. (2) Samples will be collected to fill data gaps in site characterization at the Antenna Field Site (which encompasses the area known as the Old Waste Disposal Site) for DRO, GRO, RRO, VOCs, and SVOCs along the shoreline of the Middle Salt Lagoon; for petroleum and to evaluate for possible presence of a buried transformer at the abandoned communications station Quonset hut; for GRO, DRO, RRO in high anomaly areas indicating high concentrations of buried waste; and a surface debris survey will be conducted to identify and map surface debris that may post a physical hazard to people using the site. (3) Confirmation samples will be collected from land-farmed soil at the Bulk Fuel Tank Farm to fill data gaps that resulted from insufficient confirmation sampling at the conclusion of soil treatment operations.

3/2/2007	Document, Report, or Work plan Review - other	Reviewed and sent approval letter for draft 2006 Annual Monitoring Report for the NARL Airstrip, Powerhouse, and Bulk Fuel Tank Farm Sites. This monitoring report describes visual site inspections, well installations and reinstallations, sampling activities, and presents the results of active zone ground water, surface water sampling conducted during July and September, 2005, for the Airstrip, Powerhouse, and Bulk Fuel Tank Farm Sites, and sediment sampling in the North Salt Lagoon adjacent to the Bulk Fuel Tank Farm Site during September, 2005. This is the fourth year of monitoring following soil cleanup activities at the Airstrip site and the third year for the Powerhouse and Bulk Fuel Tank Farm sites. This report shows that at this point in time, contaminant concentrations at most of the wells at each of the sites do not show clear trends. A few wells show decreasing or probably decreasing levels of one or more petroleum constituent. Data analysis shows an increasing trend in concentrations of diesel range organics in one well at the Airstrip site. No exceedance of drinking water standards was detected in Imikpuk Lake samples.

5/6/2008	CERCLA ROD Periodic Review	Reviewed and sent comments on First Five Year Review – Airstrip (Site 5), Powerhouse (Site 12), and Bulk Fuel Tank Farm (Site 13). This report reviews information on past cleanup actions and long-term monitoring at the Barrow Naval Arctic Research Laboratory (NARL) Airstrip, Powerhouse, and Bulk Fuel Tank Farm sites, evaluates the effectiveness of the past cleanup actions, and makes recommendations for the future. The report concludes that overall the actions implemented at these three sites remain protective of human health and the environment. The report recommends continuing a monitoring program similar to the past five years, but makes a few specific recommendations for modifications to the monitoring program. The report recommends an engineering inspection of the cap at the Airstrip south depression. The report makes several recommendations for the Bulk Fuel Tank Farm site, including adding lead as a contaminant of concern, assessing the feasibility of removing additional soil from the south bank area and the historical sampling location “90,” and collecting additional samples to evaluate the land farm soil. The report also recommends meeting with the Ukpeagvik Iñupiat Corporation (UIC) and the Bureau of Land Management (BLM) to resolve concerns regarding the Powerhouse site.

5/15/2008	Document, Report, or Work plan Review - other	Approval letter sent for final 2007 Annual Monitoring Report, NARL Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm. This report presents sampling results for 2007 monitoring of active zone water, surface water, and sediment at the Barrow Naval Arctic Research Laboratory (NARL) Airstrip, Powerhouse, and Bulk Fuel Tank Farms sites, conducted in July and September of 2007. Field activities were cut short during the September sampling event when the field personnel conducting sampling at the Bulk Fuel Tank Farm were accosted by an individual with a gun and instructed to leave. ADEC was informed of the situation when it occurred, and concurred with the Navy decision to withdraw the sampling crew from the field. As a result of the incident, some of the monitoring samples scheduled for September were not collected, and the confirmation samples at the Bulk Fuel Tank Farm former landfarm location also were not collected. However, since these sites will have ongoing monitoring, future data will be available for evaluating trends and assuring protection of human health and the environment. ADEC sent review comments on the draft report on March 4, 2008. Letters for draft and final reports were sent to Grady May, USN remedial project manager.	Tamar Stephens

4/15/2009	Document, Report, or Work plan Review - other	Reviewed and sent comments on a short report titled “Optimization Review – Sites 5, 12, and 13 at Naval Arctic Research Laboratory, Barrow Alaska” (February 2, 2009). DEC received this report on March 17, 2009. This report evaluates the long-term monitoring programs for three sites at the Barrow Naval Arctic Research Laboratory (NARL): Powerhouse Site, Airstrip Site, and the Bulk Fuel Tank Farm Site. It identifies three broad issues related to frequency of sampling, monitoring wells and monitoring parameters, and natural attenuation and makes several recommendations for reducing or eliminating specific elements of the monitoring program and using the cost savings to do additional investigation to support better management of contaminant plumes or to do residual source removal. (1) The report recommends reducing the sampling frequency to one time each year instead of two times and states that a single August or September sampling event would provide a fair representation of the groundwater. DEC concurred that at present one annual sampling event would provide adequate monitoring information on these sites. Once the monitoring results indicate that a site is at or near the target cleanup levels, the sampling frequency may need to be restored to twice a year to confirm that seasonal variations in contaminant concentrations do not exceed cleanup levels. (2) The report recommends eliminating specific sampling locations from the active zone groundwater monitoring program. At the Airstrip site, WP-21 has been monitored to provide background parameters; the report concludes that it may have served its purpose in providing a benchmark for evaluating trends at the site. At the Bulk Fuel Tank Farm, the report concludes that four monitoring wells could be dropped from the program: WP-07 is too far cross-gradient from signs of currently elevated contaminants of concern; and WP-04, WP-05 and WP-06 are sited to detect plume movement toward the melt water pond, but the groundwater gradient shows that groundwater moves the opposite direction. DEC concurred. (3) The report recommends consideration of doing additional source investigation for residual sources of petroleum contamination containing free-phase petroleum, using a drill rig equipped with a membrane interface probe. DEC concurred. (4) The Optimization Review Report recommends a more focused investigation into monitored natural attenuation to provide information that might support more active plume control or source management activities. DEC concurred. Letter was sent to Grady May, USN remedial project manager.	Tamar Stephens

6/5/2013	Site Visit	DEC Staff conducted a Site visit to observe current conditions at the site.	Dennis Shepard
6/17/2014	Site Visit	DEC staff attended the Barrow Remediation Advisory Board Meeting in Barrow Alaska on June 19, 2014. The Naval Arctic Reserch Laboratory (NARL) contaminated sites were discussed and recent sampling and reporting was described in detail by the Navy RPM. A major issue for the NARL sites is the continued exceedance of contaminants above decision document specified cleanup levels and migration of contamination to surface water shoreline compliance wells. DEC staff completed site visits to NARL facility sites on June 17 and 18. The NARL facility Bulk Fuel Tank Farm Site (BFTF) was inspected to investigate community reports that a strong fuel odor is present at the during spring breakup. DEC staff confirmed a strong fuel odor is associated with the gravel pad at the BFTF. DEC staff also observed the City of Barrow Boat Launch project which is adjacent to the BFTF. The dredging of sediments for the Boat Launch breakwater had already occurred. A strong fuel odor was associated with the Dredged material. DEC staff contacted the Contractor UIC Constuction/Umiaq and asked that the soil be placed on a DEC approved liner, that a sampling analysis Work plan be submitted and appropriate analytical confirmation sampling be conducted prior to moving the material.

This memo lays out the plans for mitigating lead contamination exceeding wildlife cleanup levels in the surface soil (up to 2 feet below ground surface). For DUs 3 through 4, 11, 13, 14, 15, and 16 (lead exceeds 2002 ROD cleanup level), contaminated soil will be placed 2 feet bgs and below without requiring samples to be analyzed for TCLP lead. Approximately 100 CY of DU11 has been excavated to access contaminated soil in DU12, it is proposed that this soil also be placed below 2 feet bgs. The portion of DU11 that has not been excavated will be left in place and this soil is present between 0 and 1.5 feet bgs.	Kevin Fraley
8/19/2021	Document, Report, or Work plan Review - other	Completed review of the 2020 Annual Monitoring Report, Long-Term Monitoring, Operations, and Maintenance at the Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm. This report detailed the long-term monitoring activities conducted during the 2020 field season. This work was conducted to assess whether geochemical indicators in the active zone water are indicative of hydrocarbon biodegradation, to evaluate contaminant levels in sediments at the BFTF site, and to evaluate progress toward achieving active zone water cleanup levels (CULs) through trend analysis and comparison with CULs. Geochemical parameters indicate that natural attenuation is occurring at varying degrees across the sites but no established degradation rates have been determined at this time. Contaminant concentrations in Imikpuk Lake surface water samples obtained from the Powerhouse and Airstrip sites reaming below CULs. One shoreline monitoring well at the Powerhouse site shows an increasing trend for DRO. Results for active zone water at the Airstrip site exceeded DRO CULs at three shoreline wells. Currently, it is unclear when the active zone water at the Airstrip site will achieve CULs via natural attenuation. At the Powerhouse site, with the exception of one well, monitoring wells had at least one contaminant above CUL. At the BFTF site, the number of monitoring wells with CUL exceedances were four. Both DRO and lead were detected in the North Salt Lagoon sediments.	Kelly Walker

This work plan is for the active zone water, surface water, and soil sampling to be conducted during the 2021 field season. Active zone water and surface water samples will be collected at the Airstrip and Powerhouse sites to evaluate current contaminant levels and to determine the status of natural attenuation of contaminants through collection of geochemical indicators. Active zone water and sediment will be collected at the BFTF to evaluate contaminant levels.	Kelly Walker
8/19/2021	Document, Report, or Work plan Review - other	Review completed for the Former Barrow Bulk Fuel Tank Farm (Site 13) Remedial Action Report for the BFTF site. This report detailed the 2019 field activities conducted at the BFTF site. Seven landfarm cells were constructed to treat soils from four main areas of contamination at the BFTF. Approximately 4,550 cubic yards of soils were treated from the Gravel Pad Area, South Bank Area and the Turnaround Area. Partial excavation took place at the Turnaround Area due to proximity to wetlands and higher than expected water levels. The Historical Location "90" was not able to be excavated due to proximity to wetlands and high-water levels. Two analytical samples were collected at this location. DEC suggested NAVFAC revisit the use of Method One Cleanup Levels for this site as they may be overly stringent and not practical for remediation at this location.	Kelly Walker
8/19/2021	Document, Report, or Work plan Review - other	Review completed of the Remedial Action Work Plan for the former Bulk Fuel Tank Farm. This work plan details the remedial action activities planned at the BFTF site during the 2021 field season. Work is to include construction of a landfarming cell to treat the contaminated soils from Stockpile 5B, left over from the 2019 remedial action. Additionally, Stockpile DU17 will be transported to the Oxbow Landfill at Prudhoe Bay for disposal. Sampling activities will be conducted at Historical Location "90" and the Turnaround Area to delineate the contaminated soils still present at those locations. Soil sampling will take place in December 2021 while active zone water layer is frozen. Work plan approved July 2021.	Kelly Walker

This work plan describes the following sampling activities planned for summer of 2006 at the Barrow Naval Arctic Research Laboratory (NARL). (1) Samples will be collected as for the long-term monitoring program at the Airstrip, Powerhouse, and Bulk Fuel Tank Farm sites. As needed, any unusable monitoring wells will be replaced. Samples will include active zone groundwater samples at all three sites, surface water samples from Imikpuk Lake adjacent to the Powerhouse and Airstrip Sites, and surface water and sediment samples in the North Salt Lagoon adjacent to the Bulk Fuel Tank Farm site. (2) Samples will be collected to fill data gaps in site characterization at the Antenna Field Site (which encompasses the area known as the Old Waste Disposal Site) for DRO, GRO, RRO, VOCs, and SVOCs along the shoreline of the Middle Salt Lagoon; for petroleum and to evaluate for possible presence of a buried transformer at the abandoned communications station Quonset hut; for GRO, DRO, RRO in high anomaly areas indicating high concentrations of buried waste; and a surface debris survey will be conducted to identify and map surface debris that may post a physical hazard to people using the site. (3) Confirmation samples will be collected from land-farmed soil at the Bulk Fuel Tank Farm to fill data gaps that resulted from insufficient confirmation sampling at the conclusion of soil treatment operations.

Reviewed and sent approval letter for draft 2006 Annual Monitoring Report for the NARL Airstrip, Powerhouse, and Bulk Fuel Tank Farm Sites. This monitoring report describes visual site inspections, well installations and reinstallations, sampling activities, and presents the results of active zone ground water, surface water sampling conducted during July and September, 2005, for the Airstrip, Powerhouse, and Bulk Fuel Tank Farm Sites, and sediment sampling in the North Salt Lagoon adjacent to the Bulk Fuel Tank Farm Site during September, 2005. This is the fourth year of monitoring following soil cleanup activities at the Airstrip site and the third year for the Powerhouse and Bulk Fuel Tank Farm sites. This report shows that at this point in time, contaminant concentrations at most of the wells at each of the sites do not show clear trends. A few wells show decreasing or probably decreasing levels of one or more petroleum constituent. Data analysis shows an increasing trend in concentrations of diesel range organics in one well at the Airstrip site. No exceedance of drinking water standards was detected in Imikpuk Lake samples.

Reviewed and sent comments on First Five Year Review – Airstrip (Site 5), Powerhouse (Site 12), and Bulk Fuel Tank Farm (Site 13). This report reviews information on past cleanup actions and long-term monitoring at the Barrow Naval Arctic Research Laboratory (NARL) Airstrip, Powerhouse, and Bulk Fuel Tank Farm sites, evaluates the effectiveness of the past cleanup actions, and makes recommendations for the future. The report concludes that overall the actions implemented at these three sites remain protective of human health and the environment. The report recommends continuing a monitoring program similar to the past five years, but makes a few specific recommendations for modifications to the monitoring program. The report recommends an engineering inspection of the cap at the Airstrip south depression. The report makes several recommendations for the Bulk Fuel Tank Farm site, including adding lead as a contaminant of concern, assessing the feasibility of removing additional soil from the south bank area and the historical sampling location “90,” and collecting additional samples to evaluate the land farm soil. The report also recommends meeting with the Ukpeagvik Iñupiat Corporation (UIC) and the Bureau of Land Management (BLM) to resolve concerns regarding the Powerhouse site.

Document, Report, or Work plan Review - other

Approval letter sent for final 2007 Annual Monitoring Report, NARL Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm. This report presents sampling results for 2007 monitoring of active zone water, surface water, and sediment at the Barrow Naval Arctic Research Laboratory (NARL) Airstrip, Powerhouse, and Bulk Fuel Tank Farms sites, conducted in July and September of 2007. Field activities were cut short during the September sampling event when the field personnel conducting sampling at the Bulk Fuel Tank Farm were accosted by an individual with a gun and instructed to leave. ADEC was informed of the situation when it occurred, and concurred with the Navy decision to withdraw the sampling crew from the field. As a result of the incident, some of the monitoring samples scheduled for September were not collected, and the confirmation samples at the Bulk Fuel Tank Farm former landfarm location also were not collected. However, since these sites will have ongoing monitoring, future data will be available for evaluating trends and assuring protection of human health and the environment. ADEC sent review comments on the draft report on March 4, 2008. Letters for draft and final reports were sent to Grady May, USN remedial project manager.

Document, Report, or Work plan Review - other

Reviewed and sent comments on a short report titled “Optimization Review – Sites 5, 12, and 13 at Naval Arctic Research Laboratory, Barrow Alaska” (February 2, 2009). DEC received this report on March 17, 2009. This report evaluates the long-term monitoring programs for three sites at the Barrow Naval Arctic Research Laboratory (NARL): Powerhouse Site, Airstrip Site, and the Bulk Fuel Tank Farm Site. It identifies three broad issues related to frequency of sampling, monitoring wells and monitoring parameters, and natural attenuation and makes several recommendations for reducing or eliminating specific elements of the monitoring program and using the cost savings to do additional investigation to support better management of contaminant plumes or to do residual source removal. (1) The report recommends reducing the sampling frequency to one time each year instead of two times and states that a single August or September sampling event would provide a fair representation of the groundwater. DEC concurred that at present one annual sampling event would provide adequate monitoring information on these sites. Once the monitoring results indicate that a site is at or near the target cleanup levels, the sampling frequency may need to be restored to twice a year to confirm that seasonal variations in contaminant concentrations do not exceed cleanup levels. (2) The report recommends eliminating specific sampling locations from the active zone groundwater monitoring program. At the Airstrip site, WP-21 has been monitored to provide background parameters; the report concludes that it may have served its purpose in providing a benchmark for evaluating trends at the site. At the Bulk Fuel Tank Farm, the report concludes that four monitoring wells could be dropped from the program: WP-07 is too far cross-gradient from signs of currently elevated contaminants of concern; and WP-04, WP-05 and WP-06 are sited to detect plume movement toward the melt water pond, but the groundwater gradient shows that groundwater moves the opposite direction. DEC concurred. (3) The report recommends consideration of doing additional source investigation for residual sources of petroleum contamination containing free-phase petroleum, using a drill rig equipped with a membrane interface probe. DEC concurred. (4) The Optimization Review Report recommends a more focused investigation into monitored natural attenuation to provide information that might support more active plume control or source management activities. DEC concurred. Letter was sent to Grady May, USN remedial project manager.

Site Visit

DEC staff attended the Barrow Remediation Advisory Board Meeting in Barrow Alaska on June 19, 2014. The Naval Arctic Reserch Laboratory (NARL) contaminated sites were discussed and recent sampling and reporting was described in detail by the Navy RPM. A major issue for the NARL sites is the continued exceedance of contaminants above decision document specified cleanup levels and migration of contamination to surface water shoreline compliance wells. DEC staff completed site visits to NARL facility sites on June 17 and 18. The NARL facility Bulk Fuel Tank Farm Site (BFTF) was inspected to investigate community reports that a strong fuel odor is present at the during spring breakup. DEC staff confirmed a strong fuel odor is associated with the gravel pad at the BFTF. DEC staff also observed the City of Barrow Boat Launch project which is adjacent to the BFTF. The dredging of sediments for the Boat Launch breakwater had already occurred. A strong fuel odor was associated with the Dredged material. DEC staff contacted the Contractor UIC Constuction/Umiaq and asked that the soil be placed on a DEC approved liner, that a sampling analysis Work plan be submitted and appropriate analytical confirmation sampling be conducted prior to moving the material.

This memo lays out the plans for mitigating lead contamination exceeding wildlife cleanup levels in the surface soil (up to 2 feet below ground surface). For DUs 3 through 4, 11, 13, 14, 15, and 16 (lead exceeds 2002 ROD cleanup level), contaminated soil will be placed 2 feet bgs and below without requiring samples to be analyzed for TCLP lead. Approximately 100 CY of DU11 has been excavated to access contaminated soil in DU12, it is proposed that this soil also be placed below 2 feet bgs. The portion of DU11 that has not been excavated will be left in place and this soil is present between 0 and 1.5 feet bgs.

Document, Report, or Work plan Review - other

Completed review of the 2020 Annual Monitoring Report, Long-Term Monitoring, Operations, and Maintenance at the Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm. This report detailed the long-term monitoring activities conducted during the 2020 field season. This work was conducted to assess whether geochemical indicators in the active zone water are indicative of hydrocarbon biodegradation, to evaluate contaminant levels in sediments at the BFTF site, and to evaluate progress toward achieving active zone water cleanup levels (CULs) through trend analysis and comparison with CULs. Geochemical parameters indicate that natural attenuation is occurring at varying degrees across the sites but no established degradation rates have been determined at this time. Contaminant concentrations in Imikpuk Lake surface water samples obtained from the Powerhouse and Airstrip sites reaming below CULs. One shoreline monitoring well at the Powerhouse site shows an increasing trend for DRO. Results for active zone water at the Airstrip site exceeded DRO CULs at three shoreline wells. Currently, it is unclear when the active zone water at the Airstrip site will achieve CULs via natural attenuation. At the Powerhouse site, with the exception of one well, monitoring wells had at least one contaminant above CUL. At the BFTF site, the number of monitoring wells with CUL exceedances were four. Both DRO and lead were detected in the North Salt Lagoon sediments.

Seven landfarm cells were constructed to treat soils from four main areas of contamination at the BFTF. Approximately 4,550 cubic yards of soils were treated from the Gravel Pad Area, South Bank Area and the Turnaround Area. Partial excavation took place at the Turnaround Area due to proximity to wetlands and higher than expected water levels. The Historical Location "90" was not able to be excavated due to proximity to wetlands and high-water levels. Two analytical samples were collected at this location. DEC suggested NAVFAC revisit the use of Method One Cleanup Levels for this site as they may be overly stringent and not practical for remediation at this location.
