EXHIBIT E <br />RECLAMATION PLAN <br />Existing Conditions and Vegetation <br />As stated in the Construction Materials Regular (112) Operation Reclamation Permit Application Form, <br />Sprague Stone Quarry is designated as "Rangeland" land use. Common native vegetation at the quarry <br />consists of big and little bluestem, blue grama and side -oats grama grasses with mountain mahogany <br />and ponderosa pine. <br />Existing vegetation will remain as is and will not be disturbed until the requirement for clearing and <br />grubbing to open up new work areas (as described in the mine phasing and timetable portion of Exhibit <br />D — Mining Plan Narrative. Present conditions consist of primarily two (2) open cut areas; a north pit <br />which has a disturbed area of 2.09 acres and a south pit having a disturbed area of 2.10 acres. In <br />addition, there is 11.34 acres of disturbed area being used for storage of mined material. The total <br />disturbed area for active mining and storage is 15.53 acres. Adding the total disturbed area with the <br />reclamation areas (1.33 acres) that have been started, there is an overall disturbance area of 16.86 <br />acres. <br />As noted, the combined total disturbed (active mining, mined material storage, reclamation) acreage is <br />currently 16.9 acres. The mining operator will install tee posts with white pvc pipe over the top as <br />physical markers at each corner of the active mining area boundaries to prevent disturbance to the <br />areas outside the active phases. The working decks of the active mining phases are comprised of 20 <br />percent overburden. The estimated volume of overburden generated in the three active working decks <br />is 2,796 cubic yards. In addition to the 20 percent of overburden, there will be an average 2 foot layer of <br />waste material across the active decks that will need to be replaced. The volume of waste rock from the <br />three active working decks is 1,520 cubic yards. The push distance for the overburden that will be stored <br />on the working decks will be approximately 30 feet. However, the future total will be limited by <br />agreement on a yearly basis between the State of Colorado Division of Reclamation, Mining and Safety <br />and the Operator of the mine. This limitation will be set according to the area of disturbance that has <br />been bonded by the operator of the mine. A Phasing Map for Future Permitting and Reclamation is <br />provided as Exhibit F.2 and shall be utilized as necessary. The Exhibit F.2 will be the basis for future <br />additional active mining, mined material storage and reclamation combined with required bonding. <br />Areas per the phasing plan shall be bonded entirely by area when work encroaches into the said area. <br />Clearing and grubbing to open up new working areas will not exceed a combined total of one (1) acre <br />per annum. Annual reclamation works will commensurate with the acreage of new working areas <br />opened up the previous year to the best of the operator's ability. For example, if 0.5 acres were <br />disturbed to extend the work areas in 2014, then 0.5 acres would be reclaimed in the year 2015. <br />R:\2000\2089.00 Sprague Quarry\D0CUMENTS\PERMITS\2015 Mining Permit\For Permit Package Submittal\Exhibits\Exhibit E - Reclamation <br />Plan.docx <br />
