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
8/19/2021 Document, Report, or Work plan Review - other Review completed for the 2021 Tier II Sampling and Analysis Plan Addendum, Long-Term Monitoring, Operations, and Maintenance at the Airstrip, Powerhouse, and Former BFTF sites. 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 Tier I Sampling and Analysis Plan 2021 Diesel Range Organics Fractionation and Per- and Polyfluoroalkyl Substances Sampling for the Airstrip and Powerhouse sites. The objectives of this sampling effort are to: -Determine if PFAS are present in the soil at or near Imikpuk Lake at the Airstrip and Powerhouse sites, and if present, use this information to inform costing estimates for offsite disposal requirements for the future petroleum removal action -Determine if PFAS are present in the active zone water near Imikpuk Lake at the Powerhouse sites, and if present, evaluate whether there is a potentially unacceptable risk to human health -Determine if DRO aliphatic concentrations in the inland wells at the Airstrip and Powerhouse sites exceed the Airstrip and Powerhouse cleanup level This work plan was approved on 8/19/2021. 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

12/5/2022 Document, Report, or Work plan Review - other Bulk action entry - on this date, ADEC approved the Final 2021 Data Summary Report, Diesel Range Organic Fractionation and Per and Polyfluoroalkyl substances sampling at the Airstrip and Powerhouse Sites, Narl, Utqiagvik, dated August, 2022. ADEC agreed with the recommendation for sampling of PFAS at the Powerhouse site. Additional pre and post silica gel data is required to assess the DRO aliphatic concentrations in inland wells at the Airstrip and Powerhouse sites. Site-specific active zone groundwater cleanup levels, as established in the two sites respective Decision Documents, may need to be re-evaluated during the 2023 Five Year Review. Cascade Galasso-Irish
12/5/2022 Document, Report, or Work plan Review - other ADEC approved the Final 2021 Annual Monitoring Report, Long-Term Monitoring, Operations, and Maintenance at the Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm, Former Naval Arctic Research Laboratory, Utqiagvik, Alaska. Cleanup levels for active zone water have not yet been achieves and LTM activities will continue. Cleanup levels may need to be reviewed during the 4th Five Year Review. Additionally, ADEC approved discontinuation of sediment analysis for GRO at the BFTF, and biennial monitoring of GRO in surface water at the Powerhouse site. Cascade Galasso-Irish
8/9/2023 Document, Report, or Work plan Review - other On this date, DEC reviewed and approved the Tier II Sampling and Analysis Plan, Long-Term Monitoring, Operations, and Maintenance at the Airstrip, Powerhouse, and Former Bulk Fuel Tank Farm Sites, Former NARL, Utqiagvik, AK Dated July 2023. This work plan describes the proposed work planned for 2023 at the Airstrip (Site 5), Powerhouse (Site 12) and Former Bulk Fuel Tank Farm (BFTF, Site 13) sites. Activities to be conducted during the 2022 LTM effort include collecting surface water samples at Imikpuk Lake, collecting sediment samples at the former BFTF, determining active zone water depths and collecting active zone water samples at all three sites. The purpose of the long term monitoring (LTM) activities is to ensure the environmental monitoring outlined in the approved Decision Documents for the former the NARL sites is implemented appropriately and remains protective of human health and the environment. The NARL 4h FYR has not yet been finalized. Cascade Galasso-Irish
