Institutional Control Record Established |
ICE In the October 2004 Draft Decision Document Fact Sheets, administrative controls (ACs)were established 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. |

Meeting or Teleconference Held |
Staff met with Fort Greely and the EPA to discuss the Enhanced Use Lease program. This site is located in an area that will be leased out to developers. A medical clinic and hotel will be constructed in this area for public use. Fort Greely will maintain administrative control of the site and will restrict development within the boundary of this site. A potential exists for development of parking lot or golf course on some portion of the site, but will be reviewed at on a case-by-case basis and instrusive development will be restricted. |

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.

Update or Other Action |
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. |

ADEC staff participated in the Restoration Advisory Board meeting for Fort Greely in Delta Junction. During the meeting, Glen Shonkwiler with the United States Army Space and Missile Defense Command presented the fieldwork that was completed during the 2008 field season at Fort Greely. The 2008 fieldwork included remediating the soil in the biocell at the South Tank Farm (STF); conducting further delineation of the subsurface soils at the STF; installing four groundwater monitoring wells in the Old Post area and downgradient of the STF; completing the investigation at the MOGAS fuel line in the Old Post area; conducting additional survey of the Jarvis Creek Munitions Burial site; and conducting additional investigation of the Building 675 vault. He also presented the work that was planned to be completed during 2009. |

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. |

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. |
