The spill was located outside of secondary containment. All produced water remained on EOG Resources' location. The leak was isolated immediately upon discovery to prevent further spills. The root cause of the spill is under investigation. A vac truck was used to recover all standing fluids. The soils in the affected area were generally frozen, helping prevent the produced water from penetrating deep into the soils. 400943935 true 2015-11-27T00:00:00-07:00 40.955647 -104.361733 N/A FEE 0 0 0 false <_x0032_7_approved>false S false Simba 1-06SWD Wellhead and Facility 0 0 >=5 and <100 0 0 true false true false false 0 2015-11-27T16:59:34.157-07:00 400948523 400948523 FORM 19 SUBMITTED 400948523.pdf 400948523 400948538 AERIAL PHOTOGRAPH Simba1-06SWD_Aerial1.pdf 158462 400948523 400948539 AERIAL PHOTOGRAPH Simba1-06SWD_Aerial2.pdf 130774 400948523 400948540 AERIAL PHOTOGRAPH Simba1-06SWD_Aerial3.pdf 124779 400948523 400948596 SITE MAP Simba1-06SWD_Diagram.pdf 29469 400948523 1 2015-12-07T00:00:00-07:00 0 0 true false false false false false false The spill extent was determined visually.

The ground on location was frozen at the time of the spill, which kept the spill from penetrating deep into the soils. Soil samples will be collected during the week of 12/7/15 to determine the extent of contamination. Samples will be analyzed for BTEX, TPH, DRO, GRO, EC, pH, and SAR. Depth to groundwater is greater than 60 feet. 0 0 0 0 200 170 0 0 0 0 false false 0 0 false false false false false false true false true true true true 200 100 2 400948523 1 2015-12-07T00:00:00-07:00 true false false false The root cause of the spill was determined to be human error.
