TR-07 MINING PLAN 4. When a new oil or gas well or other facility, including any oil and gas pipeline, is established within the permit area it is important to remove from the permit the land affected by that facility, provided that land will not be used in the future by the mine operator. To accomplish this removal a prior technical revision provided a process to legally remove that land from the permit and any obligation by the operator. It is customary for oil and gas lessees to inquire as to whether a new facility will affect the mining operation and it is customary to not establish such facilities on land that is being reclaimed until such time as the land is reclaimed and released. No additional discussion. 5. Upland Mining- Due to changes in the lease, all future mining will occur in an upland area that is quite uniform. As there will be no lowland mining, the "Upland" distinction is no longer needed. See page 8. 6. Fuel Storage Requirements - APPLIES TO ALL LOCATIONS: Temporary and more permanent fuel storage areas must be properly located and protected. See page 9. 7. Topsoil removal will occur to the full depth of the topsoil, plus any overburden that may be considered useful and suitable for a plant growth medium. Topsoil stockpiling will occur at appropriate locations on land adjacent to the anticipated mining area. No additional discussion. 8. Topsoil stockpiling will occur on land adjacent to the anticipated mining area. These stockpiles will be located where erosion off of the piles will not result in excessive sedimentation into adjacent drainageways. The stockpiles should be located where a need to relocate the stockpile is minimized and where replacement of the soil on backfilled land is comparatively easy. See page 10. 9. Topsoil stockpiles will be sloped and prepared for protective seeding. The side slopes will not be steeper than 2:1. See page 11. 10. For stockpiles that are in place into a growing season, the stockpile will be monitored to watch for the growth of noxious weeds. If noxious weeds appear in the stockpile, appropriate action will be taken to eradicate the noxious weeds. Appropriate action may be the use of herbicides or physical removal of the plants. Normal"tumbleweed" development (Kochia or Salsola) need not be controlled unless the growth is so dense that it endangers the success of protection species that have been planted. See page 11. 11. Protective seeding of stockpiles,when needed, will utilize the seed mixture shown in the "Stockpile Seed Mixture" section of this Mining Plan. All topsoil stockpiles will be placed such that erosion of the stockpile does not discharge sediment into nearby drainages. See page 13 for seed mix.
