Problems/Comments

In March 2007 approximately 2,080 gallons of JP-8 jet fuel were released from an aboveground water draw-off tank and discharged inside the containment dike located at Tank 5 (Building 3241). Tank 5 is part of the hydrant fueling system. The spill was re-reported on August 25, 2010 during a construction project inside of the containment area. Contamination has been identified under the liner in the secondary containment area and appears to have reached groundwater. In August 2010 an additional spill report was received when contaminated soil was encountered during repairs to pipe supports at the tanker row fuel tank area.
