Problems/Comments

The Evergreen Road Spill is also known as Base Realignment Closure (BRAC) 73 and is located along a former petroleum, oil, lubricant (POL) distribution pipeline, near Evergreen Road on the north side of the installation. In 1982, approximately 44,000 gallons of diesel fuel spilled from a pipeline. Since the initial removal of an unknown amount of impacted soil in 1982, no further excavations have been done at the site. In 1983 the pipeline was shut down and removed; the spill area is currently undeveloped. An initial environmental investigation was performed in 1997, and gasoline range organics (GRO), diesel range organics (DRO), residual range organics (RRO), benzene, toluene, ethylbenzene, xylenes (BTEX) and semi-volatile-organic compounds (SVOCs) were detected in the soil. In 1999 two monitoring wells (73-MW-A and 73-MW-B) were installed downgradient and upgradient. Monitoring wells 73-MW-A and 73-MW-B are currently sampled for BTEX, GRO and DRO. Since 2002, there have been no analytical detections above the project action levels. Groundwater monitoring at this site is expected to continue. The corresponding U.S. Army HQAES site number is; 02341.1046.

10/1/2004	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. 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
