APPLICATION FOR TECHNICAL REVISION - 2 RECEIVED HALL GRAVEL PIT JAN 08 M-1983-142 Diririon at Miwrah rp ~Y- Mesa County This application is submitted to the Division of Minerals and Geology and the Mined Land Reclamation Board to modify the approved plan for [iris site and prepare for the development of the BLM Pi[ # 1 (M-2001-100). BLM Pi[ #1 adjoins [he Hall Pi[ and is located to the south. 1. United Companies proposes that the access road that has been developed for the Hall Gravel Pit and Ford Gravel Pit be used for access and product haulage for the BLM Pit #1. This access road/haul road has been paved and remains in good condition. The existing truck scale will remain in service for the BLM Pit #1 as well. 2. United Companies proposes that a portion of the Hall Pit be used as a gravel processing and gravel product storage area during the initial operation of the BLM Pit # 1. The part of the Hall Pit area that has been affected by gravel mining in the past consists of approximately 4 acres. This area is presently being used [o store gravel and a stockpile of reclaimed asphalt paving material that is awaiting recycling. Most of the area that is proposed for processing and storage of gravel and storage of soil materials for the BLM Pit #1 is idle at this time. The space available at the Hall Pit appears to be adequate for the proposed processing and storage uses, 4 acres. The use of the Hall Pit area will help United Companies during mining of the first 2 or 3 Blocks of the BLM Pi[ #1 Pit. United Companies owns [he Hall Pit site. 3. United Companies proposes that the 30 foot wide buffer zone at the south side of the Hall Pit be eliminated. The third problem that is addressed by this technical revision concerns a feature that was included in the original Mining Plan for this property. Thirty foot wide buffer zones were to be left hetween the Permit Boundary and all excavated areas. The Ford Pit was permitted and developed after the Hall Pit and is located adjacent to the Hall Pit east boundary. The Hall Pit's 30 foot buffer zone at the Hall/Ford boundary was eliminated from the approved Mining Plan as a part of Technical Revision-l. Eliminating the 30 foot buffer zone at the south boundary of the Hall Pit, will allow United Companies to mine all of the gravel that is present at the Hall Pit boundary with the new BLM Pit # 1. This will fully use the gravel resource at the boundary area and produce a flat floor for both pits. A flat pit floor will be an operational benefit during the mining of the BLM Pit #1 and following mining. After mining and processing activities are completed at the Hall, Ford and BLM Pit #1, a common floor
