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>false S false Unknown 0 Unknown 0 0 false false false true false 0 2014-07-17T08:10:03.657-06:00 400649221 400649221 FORM 19 SUBMITTED 400649221.pdf 400649221 400649573 FORM 19 SUBMITTED Form 19 Submittal.pdf 37628 400649221 400649679 TOPOGRAPHIC MAP Warren 29-9L & 29-16L Figure 1.pdf 1508241 400649221 400649905 ANALYTICAL RESULTS Analytical Results - Table and Laboratory Results.pdf 315231 400649221 400649906 SITE MAP Figure 2 - Warren 29-9L & 29-16L Soil Sample Locations.pdf 121097 400649221 1 SPILL 2014-07-17T00:00:00-06:00 County Roy Rudisill

Excavation activities were conducted between July 15 and 16, 2014. Approximately 290 cubic yards of impacted soil was removed and transported to Buffalo Ridge Landfill in Keenesburg, Colorado for disposal. The lateral extent of the excavation was determined in the field through the use of a photoionization detector (PID) to measure volatile organic compound (VOC) concentrations, and through the collection and analysis of soil samples as described in the Initial Form 19. The excavation was subsequently backfilled and re-contoured to match pre-existing conditions; impacted soil was left in place to be addressed by future in-situ remediation.
