Problems/Comments

Building 100, also known as Base Realignment and Closure (BRAC) Site 92 is located along the southern edge of the Allen Army Airfield (AAAF). The building was constructed with a floor drain plumbed into a septic tank in 1948 and was originally used for aircraft maintenance. Discovery of this site occurred during a 1992 assessment at which time an unlined drum storage area for 55-gallon drums of generated liquid wastes from airplane maintenance was found. Multiple removal actions and site investigations have occurred since 1992. In 2010, one monitoring well (MW-25) was installed to monitor for contamination that could have leached into the underground aquifer from BRAC Site 92. In 2016, there was a project action level (PAL) exceedance of diesel range organics (DRO). This was the first detectable result since 2010. Groundwater monitoring is expected to continue at this site. The corresponding U.S. Army HQAES site number is: 02341.1015. BRAC Site 92 is near BRAC Site 134 (DEC File Number: 141.26.014, Hazard ID: 2667) which is a steam plant near Building 101 that supported Building 100.

10/1/2004	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.	Emily Youcha
11/26/2004	Update or Other Action	In 1997 test pits were excavated and PAH were detected, benzo(a)pyrene concentrations exceeded ADEC Method Two cleanup levels (21 mg/kg). In 2002, a surface sample collected at or very near BRAC parcel 92 contained DRO at 3,100 mg/kg and a variety of PAH compounds above ADEC Method Two cleanup levels. The site status is considered "unresolved" between ADEC and SMDC. Further investigation into the migration to ground water pathway is needed. Administrative Controls have been established for this site.	Emily Youcha

5/23/2007	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.	Zachary Richter
7/2/2007	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 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.	Tana Robert

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.

Approved the Final 2014 Groundwater Monitoring and Data Analysis Report documenting the 2014 post-wide groundwater monitoring activities at Fort Greely. Analytical results from four monitoring wells at the BRAC 94 site were above cleanup levels for diesel range organics, gasoline range organics, and/or benzene. Results from one monitoring well at the South Tank Farm site were above the cleanup level for ethylene dibromide. All other results were either non-detect or below the cleanup level, including all supply well results.

DEC approved the Final 2016 Groundwater Monitoring and Data Analysis Report, Fort Greely, Alaska (November 2017). The report provides a summary of the 2016 field activities, site background, analytical results and recommendations for future sampling events at Fort Greely, Alaska (FGA). During the 2016 sampling event, 39 wells were sampled at nine site locations. Of those 39 wells sampled, seven wells contained one or more exceedances of the project action limits for diesel range organics (DRO), ethylene dibromide (EDB), benzene and 1,2,4-trimethylbenzene. The FGA monitoring wells will continue to be sampled.

The document summarizes site cleanup history for the Building 100 Drum Storage Area (FGLY-015). The U.S. Army is recommending the site be closed with institutional controls (ICs). DEC disagrees the site is ready closure based on the site information showing undelineated soil exceedances to the northeast and southwest, and only one groundwater well (MW-25) present at the site. A comment letter was sent requesting the U.S. Army address the data gaps before the site can be closed.
