Exhibit D — Reclamation Plan (a) Timing, procedure, criteria and material for overburden replacement As stated above in Exhibit C — (c) overbu, den iz. minimal and is sutticient quality to be used in Base course and till material. Fractured/weathered basalt block., and un -graded talus/colluvial material will Be mined and hauled unless used onsite Tor the access ramp or storm -water berms. There will be no stockpiles oT waste rocR or overburden. Any topsoils/usable surface material or usable crusher fines will be stockpiled Tor reclamation. If topsoil stockpiles are to be left for more than 1 growing season, they will be seeded with the recommended seed mix provided By tRe DRM&S for the ivi-.iyy4-022 permit. (DMG 5-12-94 Pre -Operation Inspection Report, attached) Mr. Charles Peacock (and the QED bapervisors) with the Colorado First SCD- NRCD in Craig, Colorado, have Been contacted as to commentz and recommendations. A copy of the DRM&S Reclamation recommendations made Tor the previous operator Wa> >ent for SCD approval. The SCD recommendation is to continue to use the DMG's 5-12-94 recommenclatimiz. Find copies of the communication with SCD in Exhibit J- Mailing Notices Reclamation will commence when the tloor of the pit is level with County Road 1 on the KL4 acre site. Overburden i., minimal so it will Be spread with a trackhoe, loader or dozer. It it is to be hauled it will Be loaded ;nto track. since overburden is minimal it will Be spread at an even minimal depth. The .62 acre site will be reclaimed when it will not be needed as a storage site. (B) The maximum gradient of reclaiFFed slopes. The maximum gradient of reclaimed dope., will Be 2:1. These slopes will Be located along the western and northern pit perimeters as shown on the Exhibit E — Reclamation Plan Map, and will have an average slope length of 30 to 40 teet. These slopes are expected to grade into possible high angle to near vertical un- weathered outcrop similar to the current reclaimed ediing site topographic profile only slightly expanded to the west and north oT the 1.34 -previously min ped and reclaimed area" shown on the map and photographs. PossiBle total length of stabilized un -weathered high angle slopes to sheer tate high wall along the (western and) mostly north side oT an ultimate 6 acre disturbed area would be approximately 500 teet in length. The residual high wall would be located generally along the "ea.,t-west" 20 year limit line shown on the Exhibit E Map i he verTical walls will not be seeded. The 2:1 slopes with fines and rocR will be hydro Seeded according to the specification. i he 2:1 slopes in non -consolidated material will have a Feign percent of rock with very little tines. The rock had jagged and pointed edges which tit together and stabilize the 2:1 slope. i he 8.14 acres to be mined is not fenced a, id i3 not protected for rangeland in the tuture. The proposed slope configuration for the .62 acre stockpile area is the slope that is present now as will not mine the area just store material. (c) Specific measures to be taRen to re -vegetate the site. 1. Stockpiled surfface material is minimal zo it will Be spread even. Fines and useaBle other crusher Tines will Be replaced over the Tinal grade surface on the lower grade slopes and tlatter operations area. Steep Higher angle slopes and rocR face will Be mined at ihiz time to un -weathered rock and scaled and stabilized similar to the current site topographic profile. The .62 acre storage area will have very little, 2-3", of top soil removed. i he rock and other materials will Be Bladed with a blade and removed. The numBer of acres in the lower grade will Be 2 acres and the flatter operation area will Be 2 acres.
