CF&I Steel Corporation Dolomite Quarry Permit M-77-376 Revised Reclamation Plan and Timetable January 20, 1987 Reclamation of the Dolomite Quarry will be in conformance with the current plan as to the methods and overall reclamation design. Future active mining will now be limited to the current quarry floor. Reclamation of all inactive areas will begin as soon as possible a~cordin to the re~5gd time_t~ble_bgto~i. ~Reclamaiion o~ ac ive~ill be performed when mining ceases. As areas become depleted, they will be reclaimed. Reclamation of all currently inactive areas was started during 1987. Earthwork for the reclamation of the inactive areas will be completed during 1988 and all areas will be seeded during the first planting season thereafter. Monitoring and maintenance of these areas will continue until fully released by the Division. All reclamation will conform to the previously approved plan with respect to slope stabilities, seed bed preparation, soil amendments, and seeding mixtures and rates. Fines material from the active operation will be u~ as a topsoil substitute w er~neecTed. -Configuration and final contours of the inactive areas will be changed to reflect the conditions as they exist today rather than i:hose previously anticipated in the earlier reclamation plan. ~Below.is a detailed plan and schedule for reclamation of the inactive areas. Spring 1988 1) Complete slope reduction and establish drainage in Echo Canyon. 2) Evaluate success of grading and revegetation done during 1987 and repair or regrade those areas where erosion is evident and establish drainage channels where necessary. Summer 1988 1) Demolition of structures which would not enhance the post mining land use (grazing) and prepare these areas for revegetation. 2) Reduce berms along roads in inactive areas and prepare them for revegetation. Stabilize outslopes of all roads within the permit area. 3) Pry ewe benches above active quarry for revegetation. Fall 1988 Seed bed preparation, fertilization and seeding of all graded areas including Echo Lanyon, quarry benches, old quarry, shop area, inactive roads and active road outslopes. 1989 & Following Reclamation of any inactive areas not previously reclaimed. At the end of this year all inactive areas will be reclaimed, monitoring and maintenance of all areas will continue until the inactive areas are fully released by the Division.
