There were no indications that the dump lines, water tank, or fittings were leaking, and the volume of the release is unknown. The tanks and associated lines were cleaned in preparation for decommissioning. A groundwater sample was collected and analyzed for benzene, toluene, ethylbenzene, and xylenes (BTEX). Laboratory analytical results, received on August 26, 2014, indicated benzene concentrations above the COGCC Table 910-1 standards, making this release reportable. Groundwater analytical results are presented on the attached table and laboratory analytical report. 328075 400676395 false 2014-08-26T00:00:00-06:00 40.231925 -104.764351 FEE 1 0 0 false <_x0032_7_approved>true S false 0 >=1 and <5 >=1 and <5 0 0 false false false true false 0 2014-08-29T11:34:34.627-06:00 400971277 400971277 FORM 19 SUBMITTED 400971277.pdf 400971277 400971297 OTHER UPRC 63N66W15SENW (15-6K & 3K) - Form 27_011416.pdf 4943636 400971277 1 SPILL 2014-08-26T00:00:00-06:00 County Roy Rudisill
