EXHIBIT E RECLAMATION PLAN Existing Conditions and Vegetation As stated in the Construction Materials Regular(112)Operation Reclamation Permit Application Form, Arkin's Park Stone Quarry is designated as "Rangeland" land use. Common native vegetation at the quarry consists of big and little bluestem, blue grama and side-oats grama grasses with mountain mahogany and ponderosa pine. Existing vegetation will remain as is and will not be disturbed until the requirement for clearing and grubbing to open up new work areas. Present conditions consist of primarily five (5) open cut areas that are actively mined and are labeled A-E in Exhibit C.1; Pit "A" is approximately 2.86 acres of disturbed area, Pit "B" is approximately 2.82 acres of disturbed area, Pit"C" is approximately 4.42 acres of disturbed area, Pit "D" is approximately 3.72 acres of disturbed area and Pit "E" is approximately 3.62 acres of disturbed area. In addition, there is 35.0 acres of disturbed area being used for storage of mined material and 3.0 acres of disturbed area used as topsoil storage.The total disturbed area for active mining, mining operations and storage is 55.4 acres. The mining operator will install tee posts with white pvc pipe over the top as physical markers at each corner of the active mining area boundaries to prevent further disturbance to the areas outside the permit boundary.The working decks of the active mining pits are comprised of 20 percent overburden. The estimated volume of overburden generated in the five active working decks is 8,388 cubic yards. In addition to the 20 percent of overburden, there will be an average 2 foot layer of waste material across the active decks that will need to be replaced. The volume of waste rock from the five active working decks is 4,560 cubic yards.The push distance for the overburden that will be stored above the working decks will be approximately 30 feet. However, the future total will be limited by agreement on a yearly basis between the State of Colorado Division of Reclamation, Mining and Safety and the Operator of the mine.This limitation will be set according to the area of disturbance that has been bonded by the operator of the mine. Clearing and grubbing to open up new working areas is not expected to exceed a combined total of one (1) acre per annum. Annual reclamation works will begin with the acreage of new working areas opened up the previous year to the best of the Operator's ability. For example, if 0.5 acres were disturbed to extend the work areas in 2015, then 0.5 acres would be reclaimed in the year 2016. Vegetation Restoration Mulch Application: Topsoil shall be removed and segregated from other spoil. Areas of topsoil replacement will be approximately 4" to 6" in depth. Topsoil will be stored in a designated area near the upper side of the R:\2100\2186.00 Arkins Park Permit\DOCUMENTS\AMENDED PERMIT\Exhibit E-Reclamation Plan.docx
