DEC received a draft Quality Assurance Project Plan, Remedial Investigation (RI) for PFAS at Various Sites, Eielson AFB, Alaska. The purpose of the RI is to characterize the nature and extent of 24 PFAS compounds, specifically perfluorooctane sulfonate (PFOS),perfluorooctanoic acid (PFOA), and Perfluorobutane sulfonic acid (PFBS) through the application of adaptive high-resolution site characterization and the development of a flux-based conceptual site model.The outcome of the RI will be (1) flux-based ranking of sources and mapping of migration pathway(s), and (2) delineation of soil, groundwater, sediment, and surface water impacts. |

Document, Report, or Work plan Review - other |
DEC approved the Final 2025 Environmental Restoration Program Atlas, Eielson Air Force Base, AK, November 2025 on this date. The goal of the document is to present the Land Use Controls for the source areas at Eielson Air Force Base. The figures in the Atlas provide the Decision Document (DD) Controls, Base Administrative Controls, and ICs for each site, along with present groundwater plumes, restricted soil excavation areas, and contaminants of concern at the sites. The Restoration Atlas is required per the Institutional Control/Land Use Controls (IC/LUC) Settlement Agreement signed April 15, 2013. The Atlas was issued for the first time in 2017 and is updated annually. |

DEC reviewed and provided response to one remaining open comment for the Draft Final 2025 Institutional Controls/Land Use Controls Annual Report, Eielson Air Force Base, Alaska, May 2026. The goal of this report is to review the individual institutional controls (ICs) established by the Record of Decision (ROD) documents for Installation Restoration Program (IRP) source areas with enforceable ICs and other contaminated sites currently with land use controls (LUCs) in effect. DEC appreciates the hard work that went into this document, and the issues that were addressed during inspections when possible. DEC may provide additional recommendations during the meeting. DEC requested further discussion and a presentation regarding the Air Force’s general recommendation to, “Remove fencing/signage requirement from LUCIP.”, for sites FT009, DP028, DP029, SS035, SS036, SS037, SS063, SS064, FT092. The presentation was given at the July 2026 Eielson Air Force Base (EAFB) RPM meeting to the DEC and EPA Remedial Project Managers. Both DEC and EPA requested more information regarding the specifics for each site, and to have the Air Force present the information again at a future EAFB RPM meeting. DEC is requesting that due to further discussion needed, the Recommended Due Date for the general recommendation made by the Air Force (that is referenced above) is extended to December 2027, and that this general recommendation is carried over to the 2026 IC/LUC report. If the comment is accepted than the next step will be to approve the final version of the report. |
