The volume of the release is unknown. The impacts were determined to be reportable based on the volume of hydrocarbon impacted soils removed from the location. The impacted soils were removed from the site and hauled to the licensed Kerr-McGee Land Treatment Facility for processing. A topographic Site Location Map showing the general location of the release is attached as Figure 1. 328886 400913284 false 2015-10-07T00:00:00-06:00 40.173799 -104.797669 FEE 0 0 0 false <_x0032_7_approved>false S false >=5 and <100 0 0 0 0 false false false true false 0 2015-10-07T14:51:14.233-06:00 400917204 Submitted on behalf of Erik Mickelson. 400917204 400917204 FORM 19 SUBMITTED 400917204.pdf 400917204 400918975 TOPOGRAPHIC MAP Bluffs_White_W62N66W_5NWNE_Fig1_area_20151007.pdf 556835 400917204 400919408 ANALYTICAL RESULTS Table 1.pdf 19037 400917204 1 SPILL 2015-10-07T00:00:00-06:00 Weld County Roy Rudisill

The excavation was progressively expanded both laterally and vertically to reach the extent of impacts, as indicated by laboratory analytical results. Soil sample (SS) locations SS-1 through -16, -18, -21B, and -22 through -25 were below COGCC Table 910-1 allowable concentrations. Soil sample locations SS-17, -19, -20, and -21 exceeded Table 910-1 allowable concentrations, but were within the interior of the excavation. Laboratory analytical results from soil samples collected from the excavation sidewalls and base were below Table 910-1 allowable concentrations. The regional site location is provided as Figure 1. Laboratory analytical results are included in the attached Table 1. Site geology includes sandy clay. 262 4 1800 1270 315 1300 550 Following further excavation activities, the dumpline that had leaked, thus causing the historical release, was decomissioned. Soil samples collected from the base and perimeter sidewalls of the excavation were below COGCC Table 910-1 allowable concentrations of contaminants of concern.
