Site investigated under BRAC. DRO was detected in soil above migration to groundwater cleanup level (21,000 mg/kg). Army is expected to propose Method II cleanup levels without migration to groundwater pathway. |

Institutional Control Record Established |
In the October 2004 Draft Decision Document Fact Sheets, administrative controls (ACs)were estblished in order to minimize risk to human health and the environment. The site is included in the post’s Geographic Information System (GIS), a tool used in the Dig Permit process for notifying contractors, workers, and base personnel of the potential for contamination to exist at this site. The Dig Permit process is used to prevent installation of water production well(s) through the contaminated area, and prevent removal of contaminated material from the site to off-base locations or to environmentally sensitive areas. If future land disturbance activities at the site encounter contamination, the contaminated material encountered will be properly remediated or disposed of in accordance with applicable regulations. The site will be included in 5-year reviews to periodically verify compliance with the ACs. |

Update or Other Action |
ADEC reviewed a report titled "Comprehensive evaluation of groundwater monitoring program Fort Greely, Alaska". The report discussed the existing monitoring network at Fort Greely and the parameters evaluated in ground-water sampling events. ADEC recommended additional investigation into infiltration and vertical hydraulic gradients. ADEC also recommended additional monitoring wells in the Old Post area and more ground-water monitoring at certain specific sites. |

Update or Other Action |
Staff reviewed a sampling workplan for BRAC 48, which is the fenced waste accumulation area next to building 626. However, a report titled "Chemical Data Report, Building 626, Fenced Storage Yard, Spring 1995" indicates sampling already occured for petroleum, VOCs, and metals. Six borings were completed to 4.5 feet and 3 samples were collected from each boring. Contamination exists mainly in the surface soil. The maximum detected petroleum concentration was 25,000 ppm and all other analytes were well below the cleanup levels or non-detect. It was thought that the petroleum is a lubricating or other heavy oil. Staff recommended removal and treatment of the petroleum contaminated soil, rather than additional sampling. |

Interim Removal Action Approved |
Staff approved a plan to remove petroleum contatminated soil from BRAC 48 (not BRAC 130). Staff requested that they collect confirmation samples at excavation pit at Building 626 Waste Accumulation Area in accordance with 18 AAC 75 or 18 AAC 78 excavation sampling regulations. In order to achieve a full closure, concentrations must be below Method Two soil cleanup levels. Contamination will be placed in the Petroleum, Oil, and Lubricants stockpile at the landfill. Soil information such as quantity, concentration, origination, etc. should be recorded. The stockpiled soil must be stored in accordance with 18 AAC 75 and 18 AAC 78 regulations. When the method of treatment for BRAC 48 Waste Accumulation Area petroleum-contaminated soil is determined, please submit a treatment plan to the Contaminated Sites Program for approval. The site still may have contamination associated with the UST (BRAC 130). May want to separate this site (BRAC 48) out from BRAC 130 if they can obtain closure w/ BRAC 48. |

Update or Other Action |
The Alaska Department of Environmental Conservation (ADEC) received the Groundwater Monitoring and Data Analysis Work Plan Fort Greely, Alaska on April 27, 2007. This work plan abides by the 2005 Final Work Plan with modifications to the wells and analytical parameters to be monitored particularly the addition of polycyclic aromatic hydrocarbon analysis at monitoring wells MW-12, MW-13, and MW-14. Additionally, the pump type used in sampling the monitoring wells will be changed by replacing the Grundfos Ready Flow pump with a QED Sample Pro 1.75 inch bladder pump and QED MP10 controller, or equivalent. All other sampling methodology will remain the same as the 2005 Final Plan. The final modification to the 2007 Work Plan is the addition of Volatile Organic Analysis/1,2-dibromoethane monitoring at drinking water wells ECP2 and ISFAC at the missile field. An updated list of wells to be monitored, and the parameter for analysis from each well, for upcoming sampling events has been provided to replace Table 5 of the 2005 Final Work Plan. ADEC has completed its review of this document and has found that the Groundwater Monitoring and Data Analysis Work Plan Fort Greely, Alaska for 2007 adequately meets the requirements set forth in 18AAC75.355, and with the addition of the previously agreed upon amendment, this work plan is approved.

The Alaska Department of Environmental Conservation (ADEC) has completed its assessment of the environmental laboratory data and quality assurance requirements as set forth in ADEC Technical Memorandum 06-002 for the Groundwater Monitoring 2006 Analytical Data Report Fort Greely, Alaska, February 2007. The report adequately addresses the requirements set forth by ADEC for both laboratory data packages and Quality Assurance (QA) Summaries, therefore the report is approved. |

Received 2006 Remedial Investigation for Fort Greely. Excavations began at the 1995 test boring locations. An approximate 6 foot by 3 foot rectangular pit 4 foot deep was excavated. Six confirmation grab samples were collected after excavation at four feet bgs. The grab samples were analyzed for DRO, GRO and BTEX. All the sample results met ADEC cleanup levels. A total of 28 cubic yards of contaminated soil was transported to the POL yard for proper disposal. |

Document, Report, or Work plan Review - other |
ADEC staff reviewed the document titled Draft 2008 Groundwater Monitoring and Data Analysis Report, Fort Greely, Alaska, dated March 2009. The Fort Greely groundwater monitoring program consists of monitoring wells that were installed during investigation activities on FGA from 1997 to the present. DEC approved a comprehensive groundwater monitoring approach in the 2005 Work Plan. Yearly modifications to the 2005 workplan are incorporated as needed to address environmental program objectives. Monitoring well locations and sampling frequency have been chosen to provide site specific monitoring where necessary, and comprehensive coverage for the old post and main cantonment areas of Fort Greely. Currently, a total of 30 wells are included in the groundwater monitoring program: 11 of these are sampled during the spring and fall on even numbered years, two drinking water wells are sampled quarterly, and 17 monitoring wells are sampled semi–annually. This report summarizes the 2008 groundwater monitoring efforts. A letter detailing staff comments has been provided to the Army. |

Final Cleanup Report Reviewed |
ADEC provided comments for the Environmental Summary Report: FGLY-099 MISC UST/AST Sites, Draft (dated September 27, 2022) to the U.S. Army. The report summarized thirteen sites the Army is recommending for site closure. Four of the thirteen sites (Bldg 320, Bldg 340, POL Storage Area and the Old Power Generation Building) ADEC does not concur with the site closure recommendation at this time. ADEC recommended the four sites needing additional site characterization be removed from the Environmental Summary Report. |

DEC provided responses to comments for the Environmental Summary Report: FGLY-099 MISC UST/AST Sites, Draft (dated September 27, 2022) to the U.S. Army. Thirteen sites were evaluated for closure with this summary report. Four sites requested for closure do not meet the closure criteria. Additional site characterization work is needed before the four sites can be closed. |
