Site Visit |
On August 23-24, DEC performed a site visit at all the Cold Bay Fort Randall FUDS sites: Beach Seeps/DDA, UST 1 (former E-West Runway) and Milepost 4 (MP4) and Milepost 5 (MP5) areas. In addition to the site visits, DEC also attended a public meeting to discuss results from previous work and go over upcoming work. |

DEC has approved the Final Phase I Remedial Investigation (RI) Report Milepost Four (MP4) Frosty Road Fuel Storage Area and Milepost Five (MP5) Frosty Road Encampment Area Formerly Used Defense Sites (F10AK084505 and F10AK084506) Cold Bay, Alaska, dated October 2017. A total of 690 features of interest were identified between the MP4 and MP5 areas in 2015 (345 features identified at MP4 and 345 features identified at MP5). During the Phase I RI fieldwork in 2016 at MP4, 36 of these 345 features were sampled. Eight of the 36 sampled features were above the remediation investigation screening level (RISL) for volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PAHs) and metals (arsenic, chromium, lead and vanadium). During the Phase I RI fieldwork in 2016 at MP5, 62 of the 345 features were sampled. Twenty-one of the 62 sampled features were above the RISL for diesel range organics (DRO), residual range organics (RRO), VOCs, PAHs, metals and polychlorinated biphenyls (PCBs). Out of the 690 features, 122 of them were tent sites, and only 25 of the tent sites were sampled. Sample results for DRO and RRO were detected below the most stringent of the Method Two cleanup levels. The background evaluation study described in this final report is expected to be applicable to most of the sites around the Cold Bay MP4 and MP5 areas, however some sites in these areas may have geological or hydrological conditions which vary substantially from those of the background sample locations. Thus, application and use of the background values tabulated in this final report will be evaluated on a site by site basis. The next step for this site is a Phase II RI to occur 2018-2020. |

ADEC approved the "FUDS 2019 Revised Cold Bay Operations and Maintenance Work Plan Addendum, Fort Randall, Cold Bay, Alaska". This revised work plan addendum (WPA) details general operations and maintenance (O&M) of onsite remediation systems, biannual and annual sampling, and general reporting for the Drum Disposal Area (DDA)/Beach Seep Area (BSA) and Underground Storage Tank (UST) 1 (formerly the East-West Runway [EWR] site) project sites at the Fort Randall Formerly Used Defense Site (FUDS) (Property No. F10AK0845-02) in Cold Bay, Alaska (Figure 1-1). This revised 2019 WPA supplements the 2018 WPA (U.S. Army Corps of Engineers [USACE] 2018c). |

ADEC approved the "2018 Cold Bay Annual Report, Fort Randall, Cold Bay, Alaska". This report summarizes 2018 operations and maintenance (O&M) for the Cold Bay highvacuum
extraction (HVE) and bioventing treatment systems, HVE system upgrades, and the annual groundwater monitoring results at the former Fort Randall site in Cold Bay, Alaska. The
performance period of January through December 2018 was Year 20 of O&M for the HVE system and Year 11 of O&M for the bioventing treatment system. |

DEC received a Findings and Determination of Eligibility (FDE) for the Cold Bay-Fort Randall (F10AK0845) Formerly Used Defense Site (FUDS) on February 1, 2023. The document was reviewed, and DEC concurs with the findings described in the FDE. |

Offsite Soil or Groundwater Disposal Approved |
DEC approved a request to transport five, 55-gallon drums of investigative-derived waste from the designated conex at Milepost 5 in Cold Bay, Alaska to the Chemical Waste Management of the Northwest in Arlington, Oregon. The media is a mix of soil and spent granular activated carbon (GAC). DEC requested a copy of the lab report along with the signed and completed transport request form be sent with the investigative-derived waste. |

DEC provided comments for the "Draft Phase IV Remedial Investigation and Baseline Risk Assessment, MP4 Frosty Road Fuel Storage Area and MP5 Frosty Road Encampment Area FUDS Work Plan, Cold Bay, Alaska, (dated May 2025)" to the U.S. Army Corp of Engineers. The work plan proposes an approach and procedures for addressing data gaps at the MP4 and MP5 sites, as well as proposes a baseline risk assessment for the two sites. |
