Pumping operations were immediately shut down. Approximately one barrel of produced water released from the broken line and soaked into the ground. Soil samples were collected from within the spill area and submitted for laboratory analysis. 400913402 true 2015-10-07T00:00:00-06:00 39.488500 -108.121700 FEE Withheld for Privacy Reasons 0 0 0 false <_x0032_7_approved>false S false 0 0 >=1 and <5 0 0 false false false false true 0 2015-10-07T15:45:26.75-06:00 400918468 400918468 FORM 19 SUBMITTED 400918468.pdf 400918468 400919747 TOPOGRAPHIC MAP Topographic Map.pdf 1020094 400918468 1 SPILL 2015-10-07T00:00:00-06:00 Surface Owner Surface Owner

From that point, Caerus was conveying this water to a pipeline riser owned by WPX southeast of their GR 14-28 pad location (COGCC Location ID 335152). This riser connects to a 12" steel pipeline that was being used to deliver water to our H2-797 pad location (COGCC Location ID 439917) for completions operations. In order to convey this water to the H2-797 pad, pumps were being utilized. During startup on the morning of 10/7/2015, the pump operator made an operational error causing the pressure within the above-mentioned 12" pipeline to increase to 3,800 pounds per square inch, which was the burst pressure for that type of pipe. As a result, the pipe split. 0 0 0 0 1 0 0 0 0 0 false false 0 0 false false false false false false false false true true false true 65 15 3 Thread was being aborted.
