The suspected produced water gathering pipeline was isolated to stop the spill of produced water. Excavation was started on March 31st, to determine the exact source of the release. Based on the spill footprint and known depth of the pipeline, it appears that the release will be greater than 100 barrels outside of secondary containment. An emergency berm was constructed on the edge of the ROW to capture any produced water before leaving the ROW. Oxy found no evidence of down-gradient surface water impacts in the drainage west of the spill based on an investigation conducted on March 31, 2015. 400818078 true 2015-03-30T00:00:00-06:00 39.534316 -108.232625 OTHER (SPECIFY) Oxy Private 0 0 0 false <_x0032_7_approved>false S false Rangeland 0 0 >=100 0 0 true false false false true 0 2015-03-31T11:40:32.673-06:00 400821757 400821757 FORM 19 SUBMITTED 400821757.pdf 400821757 400822164 AERIAL PHOTOGRAPH Pipeline ROW spill_3.30.15_aerial.pdf 453122 400821757 400822165 TOPOGRAPHIC MAP Pipeline ROW spill_3.30.15_topo.pdf 621515 400821757 1 SPILL 2015-03-31T00:00:00-06:00 COGCC Stan Spencer

Once the extent of contamination has been determined, Oxy will collect soil samples of the impacted material to determine the feasibility of on-site treatment or if the material will all be taken off-site for disposal. 0 0 0 0 106 0 0 0 0 0 2170 false false 0 0 false false false false false false true false false true true false 71 20 400821757 1 2015-04-09T00:00:00-06:00 false true false false The spill location was hydro-excavated to determine the point of pipeline failure. The spill was due to threading failure immediately behind the flange on the fiberglass pipeline.
