NOTE: One barrel of oil is 42 gallons (I added the conversion to gallons in red and added emphases)

Sept. 12, Kerr-McGee Oil and Gas Onshore LP reported that on Aug. 29, a gasket on a truck failed while an oil hauler was being loaded northeast of Fort Lupton. About 1.6 barrels of oil (672 gallons) were released; none were recovered. The driver shut the pumps down and released the pressure. A bucket was placed to catch leaking oil. Contaminated soil will be excavated. Soil sample tests will determine further remediation efforts. The cause of the spill was determined to be equipment failure.

Sept. 13, Bonanza Creek Energy Operating Company LLC reported that on Sep. 3, a tank equalizing valve was shut between two oil tanks east of Evans. This prevented oil from running over to the second tank as the first filled. About 100 barrels of oil (4200 gallons) were released, and 97 recovered with a vacuum truck. The equalizer valve was opened. The tank battery will be dismantled and soil tested. The cause of the spill was determined to be human error.

Sept. 13, Kerr-McGee Oil and Gas Onshore LP reported that on Sept. 4, an operator who was draining water from the oil tank to the water tank south of Platteville left the site without closing the drain valve. The water tank overflowed, releasing about 22 barrels of oil (924 gallons), none of which were recovered. Groundwater was impacted. Some contaminated water was disposed of, and MicroBlaze was applied to what remained. A new battery will be constructed with a geosynthetic liner. The cause of the spill was determined to be human error.

Sept. 13, Kerr-McGee Oil and Gas Onshore LP reported that on Sept. 6, an operator discovered oil staining on the ground during a daily site inspection southwest of Johnstown. The poly pipe came apart on the oil dumpline. It is unknown how much oil was released, and none has been recovered. Groundwater was impacted. Impacted soil was excavated. Ten gallons of MicroBlaze was applied to the water, and groundwater monitoring wells will be installed to determine the extent of the contamination. The cause of the spill was determined to be equipment failure.

Sept. 13, Encana Oil and Gas (USA) reported that on Sept. 6, a seal failed on a discharge line. The crew nearby shut off the mud drilling flow quickly. The spill area was scraped and the remaining drilling mud was removed using a vacuum truck. No further remediation is required. The cause of the spill was determined to be equipment failure.

Sept. 17, Bill Barrett Corporation reported that on Sept. 6, a hose from a mud pit to a pumping unit failed, causing a release of about five barrels of drilling mud, all of which were recovered. Soil samples will be collected, and if they are compliant with allowable levels of contaminates, no further remediation will be required. The cause of the spill was determined to be equipment failure.

Sept. 17, Noble Energy Inc. reported that on Sept. 11, about two barrels of water (84 gallons) released from a filling frac tank during line blow down process northeast of Eaton. One barrel was recovered. The area will be excavated and soil samples collected. The cause of the spill was determined to be equipment failure.
