Groundwater was encountered during excavation activities at approximately 4 feet below ground surface (bgs). A groundwater sample (GW01) was collected and submitted to Origins Laboratory in Denver, Colorado for analysis of benzene, toluene, ethylbenzene, and total xylenes (BTEX). Analytical results returned on October 2, 2014 indicated that benzene concentrations in the groundwater sample were above applicable COGCC Table 910-1 standards, causing this release to be reportable. The original Initial Spill Report was submitted on October 3, 2014; however, due to an error in the API number, the form was withdrawn and resubmitted on October 10, 2014, per Bob Chesson and Chris Canfield. 400706236 true 2014-10-02T00:00:00-06:00 40.184659 -104.815363 FEE 1 0 0 false <_x0032_7_approved>true S false 0 Unknown Unknown 0 0 false true true false false 0 2014-10-10T14:42:07.413-06:00 400934169 400934169 FORM 19 SUBMITTED 400934169.pdf 400934169 400934179 OTHER UPRR 42 PA X1 F27 110615.pdf 5461406 400934169 1 SPILL 2014-10-02T00:00:00-06:00 County Tom Parko
