Estimated 10 bbls of produced water leaked out of the tank into the dirt SPCC containment, saturated through a portion of the berm, and migrated 10’ to the southwest of the SPCC containment. Though the spill reached a rill on the edge of the pad, it did not leave the footprint of the pad surface, so was contained on location. 324122 400815902 true 2015-03-26T00:00:00-06:00 39.501040 -107.882523 FEE 0 0 0 false <_x0032_7_approved>false S false 0 0 >=5 and <100 0 0 true false false true false 0 2015-03-26T15:39:32.657-06:00 400818952 400818952 FORM 19 SUBMITTED 400818952.pdf 400818952 400818966 AERIAL PHOTOGRAPH RMV 137-27 Form19_Map.pdf 655022 400818952 1 SPILL 2015-03-26T00:00:00-06:00 COGCC Stan Spencer

This allowed produced water to flow out into the earthen SPCC containment structure. When the release was discovered, production personnel halted the transfer of fluids to the compromised tank. The tank was then drained of any remaining fluids and removed from service. The area impacted by the release was field screened for hydrocarbon content. Field screening results indicated residual contaminant levels below the COGCC Table 910-1 standard of 500 ppm TPH in soil. Confirmation sample was collected and submitted to an accredited laboratory for analysis. Further remedial action, if warranted, will be based on the laboratory results. WPX would like to ask for COGCC's permission to analyze the confirmation samples for an abbreviated list of Table 910-1 analytes. The samples would be analyzed for TPH, BTEX, PAHs, and inorganics. The samples would not be analyzed for metals. 0 0 0 0 10 2 0 0 0 0 4737 false false 0 0 false false false false false false false false false true false false 46 21 6 400818952 1 2015-04-02T00:00:00-06:00 false true false false The produced water tank developed a small hole near the bottom of the tank due to corrosion of the metal. This allowed produced water to flow out into the earthen SPCC containment structure. The earthen SPCC containment is being replaced with a steel SPCC containment structure with an impervious plastic liner. In addition, the replacement tank is internally coated with poly liner. All new tanks are inspected prior to placing them into the containment structures to check for possible paint chips, faulty welds, or other factors which could lead to early corrosion of the metal. The SPCC inspectors will also conduct more detailed inspections of all tanks in the field to check for possible corrosion. false false false Thread was being aborted.
