Approximately 1 barrel of oil surfaced above the flowline approximately 360 feet west of the wellhead. Excavation and cleanup activities are ongoing at the site. Confirmation soil samples will be collected from the excavation and submitted for laboratory analysis of TPH, BTEX, pH, EC, and SAR (if applicable). The analytical results and excavation details will be provided in a supplemental report.

401057389 1 2016-06-13T00:00:00-06:00 0 0 true false false false false false 6 false On March 26, 2016, four sidewall soil samples (N01@4’, E01@4’, S01@4’, and W01@4’) and one base soil sample (B01@6’) were collected from the excavation and submitted for laboratory analysis of TPH, BTEX, pH, and EC. Laboratory analytical results indicated that TPH, BTEX, pH, and EC levels were in compliance with COGCC Table 910-1 allowable levels at the extent of the excavation. Approximately 50 cubic yards of impacted soil were excavated and transported to the Buffalo Ridge Landfill in Keenesburg, Colorado, for disposal. The general site layout, release location, excavation dimensions, and soil sample locations are depicted on the Excavation Site Map provided as Figure 2. The soil sample analytical results are summarized in Table 1 and the laboratory analytical report is attached. Poorly graded fine-grained sand (SP) 20 25 520 770 750 3100 700 No further action is required. Laboratory analytical results for the confirmation soil samples indicate that TPH, BTEX, pH, and EC levels are in compliance with COGCC Table 910-1 allowable levels at the extent of the excavation. Based on the confirmation soil sample analytical results, Kerr-McGee is requesting an NFA status for this site. 1 1 1 1 1 1 0 0 0 0 3100 false false 0 0 false false false false false false false false false false false false 16 15 A total of approximately 1 barrel of oil, condensate, and produced water were released. 401057389 1 2016-06-13T00:00:00-06:00 false true false false During routine operations at the Kerr 29C-12HZ well, a flowline failure was discovered.
