The pit will be filled prior to drilling and will not lose mud unless downhole losses are encountered. No produced fluid will be contained within the pit. Drilling returns (water-based mud) will be sent to this pit after going through solids control equipment to remove cuttings. Drill cuttings will be disposed of at a licensed commercial landfill ( Front Range Landfill). Drilling fluids will be recycled at the Oxy Aggregate Recycle Facility (E&P Waste Management Facility ID: 456644). 403656949 24000 false false false 1343 5280 20 0 0 403750374 Please send any correspondence about this Form to DJREGULATORY@OXY.COM and MATTHEW_WELLS@OXY.COM Pit depth varies from 12.6' maximum to 6.5' minimum maintaining at least 2' of freeboard throughout.
