Mining reclamation is expected to be completed as proposed in the design plan within the five <br />year timeframe required in Rule 3.1.3. The anticipated schedule indicates slope liner completion <br />and pit backfill within approximately 20 months. <br />5.5.2 Public Use <br />Design of the reclaimed reservoir slope liners is anticipated for public recreational use of the <br />lined reservoirs. The crest of the slope liners is designed to slope approximately 2% into the <br />reservoirs. <br />It is anticipated Phase 5 will be backfilled to accommodate a new housing development. This <br />development is expected to offer real estate for purchase or rent. <br />5.5.3 Reclamation Measures — Material Handling <br />Approximate final site grading at the Three Bells Mine is anticipated to occur according to the <br />following: <br />3:1 (H:V) — Reclaimed, lined reservoir slopes <br />2% — Lined reservoir crest <br />0 -5% — Typical reclaimed land slope <br />All site grading will comply with CO SEO requirements for stable slope reclamation. Maximum <br />reclaimed slope will be 3:1 (H: V). Reclamation grading measures will comply with all local and <br />state erosion prevention measures. Local areas will be stabilized for erosion control as needed. <br />Areas to be backfilled (parts of Phase 4, Phase 5, Ditullio Property) will be compacted to <br />adequate compaction for stability. <br />There has been no refuse, acid - forming, or toxic producing material mined at Three Bells; no <br />production of these materials is anticipated during the remainder of the mining process. <br />Drill holes and auger holes will be filled with non - combustible materials, as outlined in Rule <br />3.1.5(6). Three Bells Mine is a surface gravel pit and quarry. The mine has no adits or shafts that <br />require closing. <br />Reclamation is not anticipated to include plans for agricultural or horticultural use. <br />MMM does not plan to use offsite structural fill as backfill material. <br />All mined material to be disposed of onsite will be disposed in manner to prevent contamination <br />of the drainage system. <br />No pollutants will be released to groundwater during reclamation. Any incidental chemical or <br />fuel spills will be contained and remediated in an expedient and appropriate manner. <br />
