Excavation of impacted material commenced on July 15, 2014, and approximately 240 cubic yards of impacted material was removed and transported to Buffalo Ridge Landfill in Keenesburg, Colorado for disposal. Soil samples were collected from the sidewalls and the base of the excavation area at 10 feet and 19 feet below ground surface (bgs), respectively. Soil samples were submitted to eAnalytics Laboratory for the analysis of BTEX and TPH. Analytical results returned on July 16, 2014 indicate constituent concentrations in the soil sample collected from the base (B01) of the excavation are in exceedance of applicable COGCC Table 910-1 standards. Additional excavation will not be completed due to unstable soils. Consequently, this release is reportable as impacted soil will be left in place for subsequent in situ remediation. 329576 400646026 true 2014-07-16T00:00:00-06:00 40.189838 -104.904904 FEE 0 0 0 false <_x0032_7_approved>true S false Unknown 0 Unknown 0 0 false false false true false 0 2014-07-17T08:10:03.657-06:00 400948972 400948972 FORM 19 SUBMITTED 400948972.pdf 400948972 400948984 OTHER Warren 29-9L Form 27, 12-07-15.PDF 4635887 400948972 1 SPILL 2014-07-17T00:00:00-06:00 County Roy Rudisill
