Rain 0 0 Lease Operator noticed bubbles emanating from a rain water puddle on location after servicing a tank vapor line. Initial investigation revealed gas was escaping from a 1inch line that is used periodically to pressure up a vapor line that runs from the tanks to the ECB to blow trapped fluid back into tank knock out pot. Gas pressure for this procedure is less than 40 pounds. Once Lease Operator relieved the trapped pressure on the 1 inch line the gas release stopped. Excavation of line revealed a corroded fitting on the line was allowing gas and fluid to be released when the line was pressured up. Staining was noted in the soil and the determination was made to remove the suspected contaminated soil. Based upon volumn of the soil removed (approiximately 15 yards) on 5/21/15 determination was made that release was more likely more than 1 BBL. 424135 400844391 false 2015-05-21T00:00:00-06:00 40.551930 -104.257710 FEE 0 0 0 true <_x0032_7_approved>false S false E&P Production Facility 0 >=1 and <5 0 0 0 false true false true false 0 2015-05-27T06:48:01.937-06:00 400852416 400852416 FORM 19 SUBMITTED 400852416.pdf 400852416 400852437 SITE MAP Figures - Siefken 11-30H.pdf 2025446 400852416 400852438 DISPOSAL MANIFEST Waste Manifest.pdf 420205 400852416 400852439 ANALYTICAL RESULTS Analytical Report - Siefken 11-30H.rpt.pdf 848283 400852416 400852474 ANALYTICAL RESULTS Table - Siefken 11-30H.pdf 49469 400852416 1 SPILL 2015-05-21T00:00:00-06:00 COGCC Rick Allison
