The failure shutdown the water injection pumps in the injection building. As the injection pumps were not active, the water tank was overfilled with fresh well water and spilled into secondary containment. The release is estimated at 700 bbl inside containment. The release is mainly freshwater. However, the tank does have residual produced water from operational maintenance of the facility. Emergency personnel responded to the release and shut-in the water well to stop the source. Vacuum trucks drained the water pooled in containment and hauled the water to the BCEOC land treatment facility. Electrical repairs have been made and the battery was returned to production. Environmental personnel will oversee the assessment and clean-up. Once the containment is fully drained, soil samples will be collected to ensure the soil is compliant with COGCC Table 910-1 standards. 400914169 true 2015-10-07T00:00:00-06:00 40.779882 -106.233506 FEDERAL 0 0 0 false <_x0032_7_approved>false I false 0 0 0 0 0 true false false false true >=100 2015-10-08T14:15:56.36-06:00 The release was mostly fresh well-water that overflowed a tank with produced water inside. 400914169 400914352 TOPOGRAPHIC MAP Figure 1.pdf 180430 400914169 1 SPILL 2015-10-08T00:00:00-06:00 COGCC Kris Neidel
