Meeting or Teleconference Held |
A two day Federal Facilities Agreement (FFA) and Stakeholders meeting was held on December 13 & 14, 2016. The main focus of the meeting was to develop a site discovery and site intake process that would satisfy requirements of the Fort Wainwright FFA, RCRA Permit, and two party agreements. The Army, EPA and DEC committed to a flowchart of the preliminary source evaluation process. Timelines were established for scoping a land use control implementation plan (LUCIP) and developing a contracting schedule for Fort Wainwright contaminated site investigations and remedial actions. Seven sites were proposed for inclusion into the FFA (three party agreement) by the Army and the RPMs documented the assignment of the regulatory path for these sites using a newly developed and agreed to signature form. |

DEC approved the 2016 Sampling Report Two-Party Site Former Building 3564, Fort Wainwright, Alaska. Five of seven monitoring wells sampled contained DRO above the ADEC cleanup level during the sampling event. Three wells exceeded ADEC cleanup levels for RRO. However, based on a plume stability evaluation using MAROS software, the Army demonstrated that the mass of the DRO plume has not migrated significantly from the source area. |

DEC approved the 2017 Sampling Report, Two-Party Site, Former Building 3564 (dated April 2018). The document describes 2017 groundwater monitoring activities at the Former Building 3564 site on Fort Wainwright, Alaska. Seven monitoring wells were sampled for diesel range organics (DRO), residual range organics (RRO), iron, manganese and sulfate. DRO and RRO remain above the DEC cleanup levels in five of the seven monitoring wells. Monitored natural attenuation (MNA) parameters indicate biodegradation is occurring at this site. In addition to the 2017 groundwater monitoring at the Former Building 3564 site, an institutional control (IC) inspection was completed. All monitoring wells inspected were found to be in satisfactory condition. Annual groundwater monitoring and IC inspections are recommended to continue in 2018. |

Document, Report, or Work plan Review - other |
DEC approved the 2018 groundwater monitoring activities and an institutional control (IC) inspection at the Former Building 3564 site on Fort Wainwright, Alaska. The following contaminants of concern (COCs) were detected above DEC cleanup levels; diesel range organics (DRO) at six out of nine wells and residual range organics (RRO) at one well. It is stated that DRO concentrations in most wells increased from 2017 to 2018 due to elevated groundwater levels, although over the long term most wells show “no trend” or “stable” concentrations. The overall trend for the DRO contaminant mass has been “increasing” since 2014. Monitored natural attenuation (MNA) parameters indicate biodegradation is occurring at this site. No compliance issues were noted during the IC inspection, although it was recommended that the damaged well AP-7187 be converted to a flush mount so that it will not be damaged further by vehicles. DEC concurs with this recommendation. The wells are recommended to be sampled once during the fall of 2019.

DEC received and reviewed the Draft Doyon Utilities Sampling and Analysis Plan (SAP) Addendum for P2046 Building 3563 Rehab Well, Pump and Motor. The SAP Addendum details removal and replacement of the existing generator and appurtenances at Building 3563. Soils excavated will be screened and sampled for gasoline and diesel range organics (GRO, DRO), volatile organic compounds (VOCs), and Resource Conservation and Recovery Act (RCRA) metals. Lead will also be analyzed with Toxicity Characteristic Leaching Procedure (TCLP) sampling methods. Soil sample results will be compared to the most stringent of either the human health or migration to groundwater cleanup levels found in 18 Alaska Administrative Code (AAC) 75.341(c) Tables B1 and B2. VOCs will also be compared to the Environmental Protection Agency (EPA) 2019 Resident Soil Regional Screening Levels (RSLs). |

Bulk action entry for Fort Wainwright Two-Party monitoring sites - on this date, DEC received and approved the final 2022 Two-Party Sites Annual Monitoring Report. Following the recommendations from the 2021 report, sampling and analysis of gasoline range organics (GRO) was discontinued at the Former Building 3564 site in 2023. However, after review of the 2022 results, GRO should continue to be analyzed further and will be included in the 2024 sampling program. Plume stability analysis for Former Building 3654 indicate increasing trends of contaminant mass. The Army will evaluate the 2023 monitoring data as well as the historical investigation and remedial activities at the site to determine if a soil removal action should be considered in the future to reduce the contaminant mass migrating to the groundwater.
A minimum of five temporary well points and two additional wells be installed at the Former Building 2250 site to further delineate the extent of the groundwater contamination. Additionally, DEC is anticipating the 2022 IDW technical memorandum with DRMO Yard Building 5010 purge water PFAS results in fall of 2023. |

DEC submitted comments on the Draft 2024 Two-Party Work Plan which details proposed site activities, data review, and reporting tasks for work to be conducted at Two-Party sites on Fort Wainwright, Alaska (FWA). The Two-Party sites planned for investigation are Neely Road, Defense Reutilization Marketing Office (DRMO) 2/Building 5010, Former Building 2250 and Former Building 3564. In addition to groundwater sampling activities, institutional control inspections will be conducted.
Notable changes from previous years’ work plans based on regulatory feedback and Army initiative include sampling wastewater for per- and polyfluoroalkyl substances (PFAS) to support site-wide PFAS Remedial Investigation (RI) work, and the addition of sampling two permanent monitoring wells at the Former Building 2250 site to delineate the petroleum contaminant plume present. |

DEC supplied comments to the Draft 2023 Monitoring Report for Two-Party Sites. The report presents analytical results and long-term monitoring optimization (LTMO) analysis of groundwater sampling performed at four Two-Party source areas on Fort Wainwright, Alaska (FWA) during the 2023 field season. The four sites investigated are the Defense Reutilization Marketing Office (DRMO) Yard (DRMO2/Building 5010), Former Building 3570 Post Exchange (PX) Gas Station (Neely Road), Former Building 2250 and Former Building 3564. Data collected from this sampling effort were compared to historical data to evaluate trends in contaminant attenuation over time. |
