In accordance with the COGCC Rule 910.b.(3)E. one grab sample was analyzed for inorganics to establish background soil conditions. As the attached lab reports indicate, all constituents of concern listed in the COGCC Table 910-1 tested below the cleanup requirements or below the background concentrations with the exception of the inorganics. Therefore, in accordance with COGCC guideline Q32 regarding inorganics, the excavation was backfilled with clean soil. Based on these results, WPX respectfully requests closure of this incident. 400725542 400725542 FORM 19 SUBMITTED 400725542.pdf 400725542 400725550 ANALYTICAL RESULTS RMV 84-34 Spill closure request attachment.pdf 2195624 400725542 1 SPILL 2014-07-23T00:00:00-06:00 COGCC Stan Spencer
