• can be achieved. Along with the environmental benefits of this cleanup, new employment opportunities and <br />increased business within the local economy will develop. <br />6.3.3(1)(a) <br />The proposed mining operation is scheduled to commence, pending permit issuance, November 1, 2009 and <br />terminate November 1, 2034. Operations may be conducted 24 hours/day. Depending on the success of the project <br />and status of Phase II operations as discussed above, the permit may be amended to extend the termination date. <br />6.3.3(l)(b) <br />Due to the nature of poor topsoil conditions at this site (0-2", previously described in Exhibit B) it is impractical to <br />salvage it for future reclamation uses. Within the Tailings impoundment area, a great deal of the pre-existing <br />surface is covered with abandoned mine waste rock. Once this material is removed for processing, it will be re- <br />impounded in the same place and reclamation will proceed as outlined in Exhibit D. There will be an intermediate <br />stockpile area on the north end of the Tailings Impoundment to stage the biosolids/woodchip blend that will be used <br />for phased reclamation of the same. See Exhibit A & E for location and Exhibit D for reclamation measures. <br />6.3.3(1)(c) <br />There is approximately 8,000 tons of abandoned mine waste rock located within the affected area of the Tailings <br />impoundment (see Exhibit A & E). This material is in three loosely defined areas and the depth of waste rock in <br />these "piles" varies from several feet to twenty feet at the center of the stockpile. The waste rock will be removed in <br />phases, commencing at the most downgradient location (next the leachate collection barrier) and progressing uphill. <br />The processed tailings will be re-impounded in the same order. There is no overburden to be removed or stockpiled <br />as a result of the proposed operation. <br />6.3.3(1)(d) <br />There is no "traditional" deposit being mined as part of this operation. Abandoned mine waste rock that was <br />• historically placed at the surface is being processed for trace precious metal content and removal of heavy metal <br />(acid forming) contaminants. A description of this is found above in 6.3.3(1)(c). A track-type excavator may be <br />employed to navigate the steep terrain to consolidate material to be more easily removed with a rubber-tired front- <br />end loader. The front-end loader and/or a dump truck will be employed to transport the material to the Mobile Mill <br />site. <br />6.3.3(1)(e) <br />There are several significant components of this operation that are locatable in Exhibit A & E. A description of each <br />follows, separated by the specific affected area. <br />Mobile Mill Site <br />Crusher Feed Pile - This is the location of a multiple day's stockpile of feedstock for the mobile crushing plant. A <br />maximum of 200 tons of material can be contained in this area for any period of time. The surface of this area is <br />concrete paved to prevent any acidic run-off and potential seepage. Additionally, the surface slopes 1/4" -1' towards <br />the rear where a 8" wide x 24" high concrete wall provides a berm to contain any run-off or sedimentation. A 10 <br />year/ 24-hour storm event (2.6" as reported by NOAA Atlas 2, Vol. III) on this pile is capable of being contained <br />here. <br />Dump trucks and/or front-end loaders deposit material here during the day. A front-end loader then will pick-up this <br />material and feed it into the Crusher Feed Bin as needed. <br />Crusher Feed Bin - This elevated, tapered bottom, steel bin is approximately 12' x 12' square and has a height of 9'. <br />The bin can hold 7 tons of material. The bin is portable, mounted on skids. A grizzley with bars spaced 8" on <br />center covers the top where the loader feeds material. At the end of the day's crusher operations, the bin is emptied. <br />The bin has a live bottom transfer conveyor to move material to the Crushing Plant Trailer. <br />Crushing Plant Trailer - This mobile crushing plant is assembled on an open trailer measuring 8' wide x 44' long. <br />The trailer is registered with the State of CO DMV as "Special Mobile Machinery". The machinery on this trailer <br />• consists o£ Crusher Feed Conveyor, Jaw Crusher Grizzley, Jaw Crusher, Roll Crusher Feed Conveyor, Roll <br />2
