Site Characterization Report Approved |
Geophysical survey in the EWR area revealed a single remaining UST. The UST appears to be sound and is not leaking. Test pitting and soil sampling around the UST revealed it ha no impacted adjacent soils. Soil sampling in the valve pits along the pipeline revealed elevated levels of fuel contamination. Although largely intact, investigation of the pipeline revealed that it had previous been properly decommissioned; there, it was abandoned in place. Three minor locations with the EWR are contaminated above regualtory limits. Evaluation of remedial alternatives at the three locations and the remoinin UST should be performed under the FS. |

Cold Bay Fort Randall HTRW Operations and Maintenance, 2014 Annual Report, Revision 0, March 2015
The report presents the results of annual groundwater sampling events at the East West Runway (EWR) and the Beach Seep Area. The results showed that free product and groundwater contamination by petroleum products is still present in both areas. ADEC suggests that the report for next year include a statistical analysis of the groundwater contaminant concentrations at the EWR and a determination if the contamination has reached a steady or declining trend. |

Update or Other Action |
2014 Operations and Maintenance Report. In 2014, exceedances were found in wells MW02, MW06, MW07, and MW08. Lead exceedances were measured in all of these wells. DRO exceeded the cleanup level in MW02 and MW07. GRO exceeded the cleanup level in MW02, MW06, and MW08. Free product was present in wells MW03 and MW05.
Recommendations include:
• Continued annual groundwater sampling
• Biannual measurements of free product and water levels
• Removal of free product using absorbent filter socks in wells and periodic hand-bailing
In addition, the groundwater COC list should be re-evaluated for future groundwater monitoring at the EWR site because DRO exceeded the cleanup level at two wells.
Note that the groundwater plume does not extend to the school |

Document, Report, or Work plan Review - other |
The Alaska Department of Environmental Conservation (DEC) approved the Declaration of Project Closure Decision and No Department of Defense Action Indicated Report, Formerly Used Defense Site CON/HTRW Project, Fort Randall Drum Burial Area (F10AK0845-03), Cold Bay, Alaska. These documents described the site history, the selected remedy and implementation, and remaining contamination in soil and groundwater. Following removal activities, diesel range organics were left in place in the soil at 15 feet below ground surface in the north trench above the migration to groundwater cleanup level, but below the human health ingestion and inhalation cleanup levels. Monitoring wells were installed in the four cardinal directions around the drum trenches to determine if groundwater had been impacted, and the contaminants of concern were not detected above cleanup levels in any of the wells. The four wells were decommissioned in 2015.
DEC concurred that this document meets the requirements of 18 AAC 75.380 – Final Reporting Requirements and Site Closure. Therefore, the Declaration of Project Closure Decision and No Department of Defense Action Indicated Report, Formerly Used Defense Site CON/HTRW Project, Fort Randall Drum Burial Area (F10AK0845-03), Cold Bay, Alaska, is approved as a site closure document.
The contaminated sites program database file number 2538.38.019, Hazard ID 2863 – “Cold Bay Fort Randall-E-West Runway”, source area ID 79884 – “Fort Randall Drum Burial Area”, will be updated to indicate this source area has a “Cleanup Complete” with no ICs determination. File number 2538.38.019, Hazard ID 2863, will remain open until all source areas in the “Cold Bay Fort Randall-E-West Runway” site are closed. |

Site Visit |
On August 23-24, DEC performed a site visit at all the Cold Bay Fort Randall FUDS sites: Beach Seeps Area (BSA)/Drum Disposal Area (DDA), UST 1 (formerly referred to as E-West Runway) and Milepost 4 (MP4) and Milepost 5 (MP5) areas. While visiting the High-Vapor Extraction (HVE) system in the BSA/DDA, DEC was notified that the HVE system had been experiencing mechanical problems and had been offline since June 2017. The HVE system was restored on August 22, 2017 but went offline again on August 23, 2017. At the time of the site visit, the contractor was working to restore the HVE system. In addition to the site visits, DEC also attended a public meeting to discuss results from previous years work and go over upcoming work. |

DEC has approved the 'Final 2016 Cold Bay Annual Report' dated August 2017, for Cold Bay Fort Randall Beach Seeps and E-West Runway sites. The final report describes the 2016 operations and maintenance (O&M) for the high-vacuum extraction (HVE) and bioventing treatment systems. The operational readiness of the HVE system dropped between 2015 and 2016, primarily due to the failure of both vacuum pumps and excessive turnaround time for repairs. It was recommended the HVE system should operate under a pulsing strategy since a 4-month forced system shutdown was effective at removing higher quantities of product. The 2016 bioventing activities (soil-gas monitoring), indicated lower levels of microbial activity were occurring across the extent of the drum disposal area (DDA) in comparison to previous years. Monitoring well results show diesel range organics (DRO) above cleanup levels across the DDA/Beach Seeps area. Stain along the beach continues to be visible. The final document also includes monitoring well results from the E-West Runway site (UST 1). DRO, gasoline range organics (GRO) and lead remain above cleanup levels. |

DEC provided a conditional approval on a work plan letter by the US Army Corp of Engineers that described upcoming fieldwork at the Beach Seeps/Drum Disposal Areas (BSA/DDA) and the UST 1 sites (formerly East-West Runway). Upcoming field activities are; groundwater sampling at all sites, measuring free product and water levels from the UST 1 monitoring wells, conduct soil gas monitoring from the soil gas probe locations and observe the beach seep stain. Upon completion of the annual sampling, broken components on the high-vapor extraction (HVE) system will be repaired and replaced so the system can be restored and remediation of the groundwater can continue. |

The document describes 2017 operations and maintenance (O&M) at the Cold Bay high-vacuum extraction (HVE) and bioventing treatment systems and annual groundwater monitoring at the Drum Disposal Area (DDA)/Beach Seeps Area (BSA) and the Underground Storage Tank (UST) 1 site (formerly referred to as East-West Runway (EWR). Nine of the 27 monitoring wells at the DDA/BSA contained free product. Only two wells at the EWR site contained free product. DDA/BSA results indicate diesel range organics (DRO), residual range organics (RRO), benzene and total aromatic hydrocarbons (TAqH) remain above their respective cleanup levels. UST 1 results indicate DRO, gasoline range organics (GRO), ethylbenzene and lead to remain above their respective cleanup levels. |
