Problems/Comments

This petroleum-contaminated site was identified while the SM-1A pipeline was being excavated during the BRAC program in 1997. During the pipeline removal, POL odor was observed by the excavation crew. The crew extended their excavation in this area to a depth of four feet bgs and removed the impacted material. One confirmation sample collected from the base of the excavation contained 2,600 mg/Kg DRO and was non-detect for GRO, RRO, BTEX and SVOCs. In 1998, three test pits were excavated to investigate the surface and subsurface soils at the location where petroleum odors were observed in the 1997 pipeline removal. Soil samples from two discrete depths within each test pit were submitted for laboratory analyses of DRO, RRO, GRO, BTEX and PAHs. All the samples met ADEC cleanup levels.

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.	Deborah Williams
2/3/2009	Meeting or Teleconference Held	Contaminated Sites (CS) staff met with Glen Shonkwiler, US Army Space and Missile Defense Command/US Army Forces Strategic Command (SMDC/ARSTRAT), February 3. A draft decision document titled “Record of Decision for Nine Installation Restoration Program Sites Fort Greely, Alaska” (ROD) was discussed. CS staff communicated recommendations addressing changes proposed by SMDC on two of the nine sites. These changes differed from the “Proposed Plan” that was released to the public in June, 2008. Comments are being prepared and briefing documents updated to address the Draft ROD. Mr. Shonkwiler also discussed several sites that were evaluated and sampled in 2008 that may be included in another decision document this year. Future planning for remediation work at some sites was also discussed.	Tana Robert
4/3/2009	Update or Other Action	The Draft Record of Decision Nine Installation Restoration Program Sites Fort Greely, AK (December 2008) document review comments letter has been submitted to the Army contact, Glen Shonwiler. The nine sites include two sections of the nuclear reactor wastewater pipeline (BRAC sites 90 & 132), a petroleum spill site along the wastewater pipeline (Station 21 + 25), three old unpermitted landfills(BRAC sites 31, 32 & 88), USTs at a former laundry facility (BRAC site 103), a waste drum storage area (BRAC site 48), and an active refuse burn pit (BRAC site 89).

10/21/2009	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.	Tana Robert
