EXHIBIT D -Reclamation Plan <br />(a) Timing, procedures, criteria and materials for overburden replacement. <br />As stated above in Exhibit C - (c), Overburden is minimal and is sufficient quality to be used in <br />base course and fll material. Fractured/weathered sandstone blocks and un-graded talus/colluvial <br />material will be mined and hauled unless used onsite for the access ramp or storm-water berms. <br />There will be no stockpiles of waste rock or overburden. Any topsoil/usable surface material or <br />usable crusher fines will be stockpiled for reclamation. If topsoil stockpiles are [o be left for more <br />than 1 growing season, they will be seeded with the recommended seed mix provided by the <br />DRM&S for the M-1994-022 permit. (DMG 5-12-94 -Pre-Operation Inspection Report, attached) <br />Mr. Charles Peacock (and the SCD Supervisors) with the Colorado First SCD -NRCS in Craig, <br />Colorado, have been contacted as to comments and reclamation recommendations. A copy of the <br />DRM&S reclamation recommendations made for the previous operator was sent for SCD <br />approval. The SCD recommendation is to continue to use the DMG's 5-12-94 recommendation. <br />Find copies of the communication with the SCD in Exhibit J -mailing notices. <br />(b) The maximum gradient of reclaimed slopes. <br />The maximum gradient of reclaimed slopes will be 2:1. These slopes will be located on the along <br />the western and northern pit perimeters as shown on the Exhibit E -Reclamation Plan Map, <br />And will have an average slope length of 30 to 35 feet. These slopes are expected to grade into <br />possible high angle to near vertical un-weathered outcrop similarto the current reclaimed existing <br />site topographic profile only slightly expanded [o the west and north of the ].34 "previously mined <br />and reclaimed area" shown on the maps and photographs. Possible total length of stabilized un- <br />weathered high angle slopes to sheer face high-wall along [he (western and) mostly north sides of <br />an ultimate 3 acre disturbed area would be approximately 500 feet in total length. The residual <br />high-wall would be located generally along the "east-west" 20 year limit line shown on [he Exhibit <br />E Map. <br />(c) Specific measures to be taken to re-vegetate the site. <br />1. Stockpiled surface material, topsoil and usable other crusher fines will be replaced over the <br />final grade surface on the lower grade slopes and flatter operations area. Steep higher angle <br />slopes and rock faces will be mined at this time to un-weathered rock and scaled and <br />stabilized similar to the current site topographic profile. <br />2. Any surface material/topsoil stockpiles will be seeded if left longer than one growing season. <br />The methods of reclamation wilt be as per the attached pre-mine application <br />recommendation supplied by the DRM&S for the M-1994-022 permit. (The SI2-94 Pre- <br />Operation Inspection Report): 2-ton straw mulch/acre and weed control will be as <br />necessary. Seedbeds will be firm and clean tilled as possible with the limited rocky <br />surface material available at the site. Final slopes in unconsolidated material graded to <br />no steeper than 2:1. Steeper slopes in competent bedrock may be steeper but should <br />blend-in with the natural terrain and must be stable. All level areas and graded slopes <br />to be seeded and vegetated. <br />3. Species recommended or reclamation are: (Rate should be doubled for broadcast seeding) <br />Bluebunch Wheatgrass 5.0 PLS per acre <br />Western wheatgrass 2.9 PLS per acre <br />Crested Wheatgrass 2.0 PLS per acre <br />Indian Ricegrass 1.0 PLS per acre <br />A total of 32.7 PLS will be required for possible 3.0 acres of reclamation. <br />
