Institutional Control Record Established |
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. If Fort Greely is transferred to another agency or party, formal ICs will be implemented at the site due to cumulative risk under the residentiall exposure scenario exceed ADEC threshold. The ICs will provide notification of restrictions for industrial/commercial exposure and will take the form of deed restrictions or similarly stringent site requirements under official post land documentation. The purpose of the IC will be to maintain industrial/commercial usage of the site and prevent future developement of the site for residential purposes. The site is currently fenced with a secured gate allowing access only by authorized personnel. |

Update or Other Action |
Lead and dioxin/furan remain as contaminants of potential concern. Background sampling and evaluation of metals was conducted in 1999 and the elevated detections of arsenic, cadmium, and chromium from the 1997 sampling were resolved as background. |

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. |

Site Characterization Workplan Approved |
Previous work from 1997-1999 detected lead, dioxins and furans at depths less than 7 ft below ground surface. In 2005, the investigation will focus on an area where soil data was previously collected in a surface depression. Samples will be analyzed for pesticides, PCBs, dioxins/furans, and lead. Two borings will be drilled in a depression area on the east side and will be advanced to 10 ft. One boring will be drilled on the east side. Samples will be collected at 5 and 7 ft below ground surface. |

Update or Other Action |
ADEC provided comments to the Draft 2006 RI for Fort Greely. According to the 2006 RI, 26 shallow (6' bgs) borings were installed to delineate the lateral and vertical extent of soil contamination. Twenty-five primary samples from varying depths at 21 locations were analyzed for dioxins/furans and lead. Three borings exceeded risk-based soil cleanup levels for dioxins/furans (as 2,3,7,8 TCDD) for residential land use in Alaska. Five borings contained total lead concentrations in excess of ADEC Method Two cleanup levels for residential use. The consultant recommends excavating the area where the lead levels exceed industrial cleanup levels. The area is estimated to a depth of six feet (approx. 30 CY). The consultant recommends that the remaining area be capped with asphalt and left in place as remediation. (An area of approximately 70 feet by 75 feet will have three feet of fill with a soild cap of asphalt. |

Document, Report, or Work plan Review - other |
ADEC acknowledged receipt of the 2nd Five-Year Review Report for the 2009 Record of Decision Installation Restoration Sites, Fort Greely, Alaska (Undated) to the U.S. Army. The document is the second Five-Year Review (FYR) for five Installation Restoration Program (IRP) sites located on Fort Greely, Alaska (FGA). The document was finalized without resolving comments from ADEC. Three sites (Former Landfills 4 and 5, Fuel Spill at Nuclear Reactor Wastewater Pipeline Station 21 + 25 and the Refuse Burn Pit) ADEC does not concur with the protectiveness determinations. The FYR did not account for potential human and ecological risks from emerging contaminants (such as PFAS). The FYR also did not address concern for sites needing notices of activity and use limitations (NAULs) placed on sites where contamination remains. |
