years where the 300,000 to 600,000 tons per year production rate is less. The following <br /> table shows the approximate time frame to finish each phase of mining: <br /> Mine Phase and Acreage Time Frame to Complete and <br /> Reclaim Phase <br /> Phase 1 — 6.92 acres 2 years and 7 months <br /> Phase 2 — 6.81 acres 2 years and 7 months <br /> Phase 3— 8.21 acres 3years and 3 months <br /> Phase 4— 9.90 acres 3 years and 10 months <br /> Phase 5 — 16.71 acres 4 years and 8 months <br /> Phase 6— 11.69 acres 3 years and 3 months <br /> Phase 7— 14.71 acres 4 years and 1 months <br /> The assumed maximum production rate is 300,000 to 600,000 tons for processed <br /> material leaving the mine each year. An average production rate of 300,000 tons per <br /> year was used to calculate the reclamation time table. The size and area of reclamation <br /> varies for each phase but generally consists of the outside mining slope being reclaimed <br /> at a 3H:1V slope with the addition of overburden, topsoil, and revegetation. For more <br /> information on sequencing and size of the reclamation activities refer to Exhibit L <br /> financial warranty calculations. <br /> Reclamation Plan and Alternate Reclamation Plan <br /> The reclamation plan attached in Exhibit F depicts the reclaimed reservoir(s) with an <br /> existing oil/gas well in the center of the reservoir with setbacks recommended per the <br /> existing slope stability study, for the area that was originally permitted, that will be <br /> implemented if an agreement with the oil/gas companies cannot be reached to re-locate <br /> the existing well. All the additional areas in the amendment will not be mined within 200 <br /> feet until an agreement with the oil/gas companies, property owner(s), or utility owner(s) <br /> can be executed or a slope stability analysis can be performed if an agreement cannot <br /> be reached. An alternate reclamation plan has also been included depicting the <br /> reservoir for the original permit without the existing oil/gas well remaining in place. The <br /> alternate plan has been submitted in the event that the surface use agreement with the <br /> oil/gas company will be finalized and the existing well could be re-located/abandoned as <br /> a part of the proposed surface use agreement. <br /> mi Derr Pit Project <br /> �T&T Consulting, Inc.
