The United States Department of the Interior, Bureau of Land Management (BLM), Uncompahgre Field Office, has received a proposed Master Development Plan (MDP) for natural gas exploration and development from SG Interests I, Ltd. (SGI) for the Bull Mountain Unit. The Bull Mountain Unit MDP describes the exploration and development of up to 146 natural gas wells, 4 water disposal wells, and associated infrastructure on federal and private mineral leases. An MDP provides information common to multiple planned wells, including drilling plans, Surface Use Plans of Operations, and plans for future production. MDPs are typically prepared for a planned cluster of wells and associated facilities near, or for multiple in-fill wells scattered throughout, an oil and gas unit or field. They have information on associated facilities, such as roads, pipelines, utility corridors, and compressor stations.
