Bureau of Land Management Appendices Royal Gorge Field Office DOI-BLM-CO-FO20-2020-0036 EA -6- Exhibit D - Reclamation Plan (continued) 2. Specify the maximum gradient of reclaimed slopes (horizontal vertical). We recommend 3:1 or gentler for purposes of stability and revegetation establishment. If you propose steeper slopes you should include a justification that supports the proposed post-mining land use and demonstrates compliance with the applicable performance standards of Rule 6. 3. Specify the thickness of topsoil to be replaced. We recommend using at least 12 inches of topsoil material to enhance root penetration and hasten revegetation. 4. Specify when the site will be seeded - late fall or early spring. Note how the seedbed will be prepared to eliminate compacted conditions (e.g., plowed, chiseled, disced). Note whether fertilizer will be utilized. and if it will, then note the type of fertilizer, application rate and how it will be incorporated into the soil. S. Specify the grass, forb, shrub and tree species to be planted and the applicable quantities. Specify the quantity of each grass and forb species as pounds of pure live seed per acre and the number of each species of shrubs and trees per acre. 6. Specify the application method for grass and forb seeding. If the seed is to be broadcast, the application rate should be twice the rate required for seed drilling, and the seed should be raked or harrowed after application. 7. Specify the kind of mulch to be used and rate of application. 8. Specify any ponds, streams, roads and buildings that will-remain after reclamation, These features must be shown on the Exhibit E - Map. If ponds are part of the reclamation plan, the slopes can not be steeper than 2:1, except from 5 feet above to 10 feet below the expected waterline where slopes can not be steeper than 3:1. Where wildlife habitat is the proposed future land use, shore lines should be irregularly shaped to promote a diverse - wildlife habitat. 9. Specify the reclamation treatment of any waste rock dumps, tailing impoundments, underground mine openings. buildings and other features specified in your mine plan but not previously addressed in the reclamation plan narrative. This should describe the measures taken to minimize disturbance to the hydrologic balance. prevent off-site effects, and provide for a stable configuration consistent with the proposed future land use. 10. The maximum amount of financial warranty for a Limited Impact Operation is S5000.00.* If you wish to commit to a $5,000.00 financial warranty, then you do not need to provide an estimate of reclamation costs. if you want to post a nancial warranty in a lesser amount, then you must provide an estimate of the actual costs to reclaim the site based on what it wouid'cost an independent contractor to complete reclamation including unit costs for the following activities as appropriate to the operation: backfilling, grading, topsoil application, seeding, mulching. fertilization, and labor. * The Board will assess a financial warranty not to exceed $15,000.00 for aqy mining operation which uses cyanide compounds in a leaching process.
