Bureau of Land Management Appendices <br /> Royal Gorge Field Office DOI-BLM-CO-F020-2020-0036 EA <br /> Exhibit C - Mining Plan (continued) <br /> 11, Specify whether the deposit/ore will be processed on-site. Processing <br /> Includes crushing, screening, washing, concrete or asphalt mixing, or <br /> milling. If the deposit/ore will be processed, then describe the nature of <br /> the process, facilities and chemicals utilized. The description should <br /> describe the measures to be taken to minimize disturbance to the hydrologic <br /> balance, prevent off-site damage, and provide for a stable configuration of <br /> the reclaimed area consistent with the proposed future land use. The process <br /> area and any'structures must be described on Exhibit E - Map. <br /> Note: If tailings ponds, heaps or vats are part of the milling process, the <br /> mine plan description should address the following: <br /> Plant Facilities. Describe the chemical types and quantities to be <br /> utilized, chemical storage and spill,containment.' Plant operation <br /> details should include tank capacities, operating•solution volumes, <br /> sump/pump back systems, curbing, etc. <br /> Tailings and Heaps." Describe:the chemical'constituents of the tailings <br /> or leached ore, the chemistry'of any leachate, anticipated impacts to <br /> ground or surface waters'and design details such as liners, diversions or <br /> chemical treatment facilities to be used to control these impacts. <br /> Drainage Control, Describe the measures used to divert upland drainage <br /> away from the site both during and after operation. This should include <br /> design details demonstrating the capacity of ditches and impoundment <br /> structures to contain operating solutions.and the volume of water <br /> generated by a significant rainfall event. <br /> Maps and Plans. Design drawings should describe specific design details <br /> for tailings ponds and embankments, heap or vat configurations, ponds and <br /> ditches, ore and tail transport systems, etc. <br /> EXHIBIT D - Reclamation Plan <br /> The purpose of the reclamation plan is to describe the timing, procedures, <br /> criteria and materials that will be used to reclaim the affected land to the <br /> proposed future land use. This plan must be correlated to Exhibit E - Map. <br /> o The description of the reclamation plan must be adequate to satisfy the <br /> requirements of Rule 3 and demonstrate compliance with Rule b. The local <br /> representative of the Soil Conservation Service can provide you with <br /> recommendations for on-site reclamation. At a minimum, you should include the <br /> following information: <br /> 1. Specify the thickness of overburden to be replaced and when the overburden <br /> will be replaced in relation to ongoing extraction. We recommend that you <br /> consider backfilling and establishing the final reclaimed grade on previously <br /> mined areas at least once per year. If you backfill and reduce slopes as soon <br /> as practicable, then you will generally be increasing the efficiency of the <br /> operation by minimizing the handling of overburden, hastening reclamation and <br /> release of the financial warranty back to you. <br /> A-28 <br />
