Oil, condensate, and produced water released from the well head and misted onto the ground surface, two isolated gravel quarry ponds, and a wetland fringe area along a dry drainage. The volume of the release is still being investigated. Excavation and cleanup activities are ongoing at the site. Confirmation soil samples will be collected from the excavation and will be submitted for laboratory analysis of TPH, BTEX, pH, EC, and SAR (if applicable). Surface water samples will be collected from the two ponds for laboratory analysis of BTEX. The analytical results and excavation details will be provided in a supplemental report.

Laboratory analytical results for the confirmation soil samples indicated that TPH, BTEX, pH, and EC levels are in compliance with COGCC Table 910-1 allowable levels at the extent of the spray release affected areas. In addition, laboratory analytical results for the surface water samples indicated BTEX concentrations were less than the laboratory reporting limit in all the surface water samples collected. Based on the confirmation soil and surface water sample analytical results, Kerr-McGee is requesting an NFA status for this site. 40 10 10 0 0 0 0 false false 0 0 true true true false false false false false false false false true 750 250 A total of 60 barrels of oil, condensate, and produced water were released. 4 400992200 1 2016-03-08T00:00:00-07:00 true false false false A release occurred at the Gee 15C-25HZ wellhead due to improper placement of equipment during workover rig operations. Approximately 60 barrels of oil, condensate, and produced water released from the wellhead and misted over an area that included two connected gravel quarry ponds. The affected equipment will be upgraded and a new process will be implemented to prevent improper equipment placement. 510 true false false 0 0 Thread was being aborted.
