Update or Other Action |
ADEC reviewed the 2000 Draft Remedial Investigation/Feasibility Study Work Plan. The ADEC commented that the proposed work addresses only the site that the USACE determined were FUDS program eligible. Additional information was requested to determine whether the proposed work is sufficient to address hazardous substances, pollutants, and contaminants resulting from past military activities in and around Yakutat. Due to the time schedules for the contracts and proposed work, these determinations were agreed to be addressed at a later time. AOC M3 was included in the work plan for investigation, but was listed as the Air Increase Group No. 1 Post Powerhouse. The Air Increase Group No. 1 50 Kilowatt Powerhouse was not included in the investigation. |

Update or Other Action |
A draft remedial investigation/feasibility study was reviewed. Recommendations were included for a more thorough investigation of the extent of contamination. Based on the information provided, the Feasibility Study is premature. ADEC recommended that the USACE not incur further expense to finalize the document until further site characterization was done. Work should occur to identify the data gaps and resolve them before any additional actions are taken. |

Site Characterization Report Approved |
ADEC approved the 2010 Supplemental Remedial Investigation Report. The Air Corps Increase Group No. 1 50 Kilowatt Powerhouse (AOC M3) investigated was not at the same location as the Post Powerhouse listed in historical documents. Additional reconnaissance of the vicinity was recommended to determine the presence of additional buildings listed in historical drawings. Six surface soil samples, two subsurface soil samples, and three groundwater samples were collected and analyzed for GRO, DRO, RRO, RCRA metals, PCBs, VOCs, and SVOCs. Benzo(a)pyrene was detected above the ADEC in one surface soil sample collected adjacent to the strip drain of the powerhouse. A concrete saddle with two vertical pipes was present to the east of the powerhouse. |

Site Characterization Workplan Approved |
The ADEC Contaminated Site Program approved the 2014 Supplemental Remedial Investigation Work Plan. Additional historical documents were included in the work plan that indicate several powerhouses in the vicinity of AOC M3. The objectives of the investigation at the Air Increase Group No. 1 50 Kilowatt Powerhouse (AOC M3) were to 1) determine the vertical and horizontal extent of the PAH contamination in soil; 2) using a visual inspection determine if the source of the PAH contamination is likely to be from FUDS activities; 3) determine whether POL-contaminated soil is present in association with the concrete saddle, and if so determine that nature and extent of the contamination. |
