Three pot holes were advanced within the pit and soil samples were collected at various depth intervals. Analytical results indicate benzene, TPH (GRO/DRO), SAR and pH concentrations/levels in soils exceed COGCC Table 910-1 concentration levels. Additional investigation ongoing. 288688 400623894 false 2014-06-10T00:00:00-06:00 39.378790 -108.056400 OTHER (SPECIFY) Noble Energy 0 0 0 false <_x0032_7_approved>false S false 0 0 Unknown 0 0 true false false true false 0 2014-06-10T09:51:43.827-06:00 400624920 400624920 FORM 19 SUBMITTED 400624920.pdf 400624920 1 2014-06-11T00:00:00-06:00 0 0 true false false false false false false The extent of impact will be deliniated through excavation activites at the facility. Impacted soil will be field screened until confirmation soil samples can be collected from the sidewalls and floor of the excavation demonstrating concentrations comply with Table 910-1 concentration levels or are within background levels. Noble will use any soil excavated from the pit with elevated levels of EC, pH or SAR as backfill material on an existing oil and gas location at a depth of 3 feet below ground surface. Based on the data provided in the Initial Spill/Release Report, Noble requests relief from Table 910-1 to analyze confirmation soil samples for a reduced analysis of BTEX and TPH (GRO/DRO). Potts-Ildefonso complex, 12 to 25 percent slopes 295 7 738 2106 754 Noble proposes treating the impacted soil on site via exsitu chemical oxidation. The excavated soil will be placed in a soil shredder that loosens and sprays impacted soil with hydrogen peroxide to reduce concentrations to below Table 910-1 levels. The treated soil will be utilized as backfill for the excavation once confirmation soil samples demonstrate concentrations are within Table 910-1 levels for BTEX and TPH (GRO/DRO). A twenty-point composite sample will be submitted for analysis from every 500 cubic yards of soil removed and treated. 0 0 0 0 0 0 0 0 2199 false false 0 0 false false true false false false false false true true false false Thread was being aborted.
