An employee left a valve open which caused uncontrolled venting from the well to over pressurize a 300 bbl produced water tank. The entire release was contained within lined SPCC containment. No fluids escaped the containment. 100 % of the volume released was recovered. 334706 400731131 true 2014-11-13T00:00:00-07:00 39.470107 -107.943220 FEE 0 0 0 true <_x0032_7_approved>false S false 0 0 >=100 0 0 true false false true false 0 2014-11-13T13:04:45.5-07:00 400737992 400737992 FORM 19 SUBMITTED 400737992.pdf 400737992 400738013 AERIAL PHOTOGRAPH AP 21-20-695 Form 19 Map 11-19-14.pdf 1328486 400737992 1 SPILL 2014-11-13T00:00:00-07:00 COGCC Stan Spencer

Vale silt loam - Silt to silty clay loam 70 2 2815 4222 3030 A production employee left a dump line valve open on one of the separators which resulted in uncontrolled venting of gas from one of the wells into the line. This over pressurized one of the 300 barrel produced water tanks and caused it to overflow. The produced water from the tank migrated out into the steel lined SPCC containment structure. When the release was discovered, production personnel shut the open dump line valve. Vac trucks were dispatched to the location to vacuum off the free standing fluids from the lined SPCC containment structure. The entire release was contained within the lined SPCC containment structure. No fluids migrated out of the containment structure. The lined SPCC containment structure performed as it was designed and captured all of the fluids from the release allowing for 100 percent recovery. 0 0 0 0 300 300 0 0 0 0 false false 0 0 false false false false false false false false true true false true 68 51 6 400737992 1 2014-11-21T00:00:00-07:00 true false false false A production employee left a dump line valve open on one of the separators which resulted in uncontrolled venting of gas from one of the wells into the line.
