The site was previously excavated to support a nearby pipeline installation and will be filled with drill cuttings for final disposal. It is anticipated that cuttings will be imported from up to six surrounding multi-well pads and be in service no longer than two years. At the end of service, the cuttings will be capped with three feet of topsoil, bringing the area back to the original surrounding grade. Oxy met with COGCC staff on Dec. 21, 2010, regarding this proposal and was directed to prepare a Form 2A and a Materials Management Plan for the proposed disposal area. The CDOW pre-consultation meeting took place on March 18, 2010. Reference area photographs are pending the 2011 growing season. 400134101 400134101 FORM 2A SUBMITTED 400134101.pdf 400134101 400134144 NRCS MAP UNIT DESC img-216142311-0001.pdf 39071 400134101 400134148 WELL LOCATION PLAT img-216142320-0001.pdf 51425 400134101 400134157 CONST.
