Problems/Comments

The Robin Road Fuel Spill, also known as Base Realignment Closure (BRAC) Site 30, is located in an undeveloped area within a power line right-of-way approximately 0.25 miles west of Robin Road. In December 1982, an aboveground pipeline ruptured and between 52,000 and 133,000 gallons of diesel fuel spilled. Soil investigation results indicated that at the time of the spill, the fuel migrated downward until it reached a less permeable, silt-rich soil layer, which caused the contamination to spread laterally. Soil borings drilled in 1997, 1998 and 2010 have delineated the boundaries of the surface and subsurface contamination. The majority of the contamination was found to be between 0-10 feet (ft) below ground surface (bgs) and 30-60 ft bgs with the vertical extent of the contamination down to 70 ft bgs. Since 1982 numerous removal actions have occurred, and the groundwater has been monitored since 1984. Since 2002, analytical results for gasoline range organics (GRO), diesel range organics (DRO) and benzene, toluene, ethylbenzene, xylenes (BTEX) have been detected, but below the project action limits (PALs). Groundwater monitoring at this site is expected to continue. The corresponding U.S. Army HQAES site number is: 02341.1045.

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. Groundwater monitoring will be conducted at a reduced scope of sampling that will be determined and agreed to between ADEC, EPA, and SMDC.	Emily Youcha
