ASPHALT SPECIALTIES CO. Exhibit E -Reclamation Plan Reclamation of the mined land of the amendment azea will be the same as for the current permit area, that of a sealed water-storage reservoir. RECLAMATION PLAN Overview The post-mining land use for the Speer Mining Resource will be for a sealed water- storage reservoir, with fringing wetland areas producing beneficial wildlife habitat. The area to be amended onto the.cunently approved permit azea will simply be added onto the overall size of the reservoir, increasing the surface azea by approximately 11 acres. The overall reclamation plan, incorporating the amendment area, is described below. Reclamation Process Land disturbance on the amendment azea will begin with removal and stockpiling of overburden (topsoil) with a scraper prior to mining. Total disturbed azeas (the affected area) can be seen on Exhibit C-2, the amended Mine Plan Map and Exhibit F, the amended Reclamation Plan Map. The total additional azea of disturbance on the amended area will be approximately. 1A.5 acres, of which approximately 11.5 will be mined. An additional 11 surface acres will be reclaimed as water storage with approximately 3.5 acres being reclaimed with regraded and revegetated shorelines and upland areas near the South Platte River on the west side of the amendment azea. Topsoil will be utilized for future surface reclamation as plant-growth medium and as a component of backfill for mined pit-slopes. Topsoil stockpile berms will be strategically located over the amendment azea to facilitate easy access for reclamation. Temporary revegetation of stockpiles will occur and be maintained until the topsoil is reused in the reclamation process. Reclamation, as backfill, will be concurrent with mining once the near-vertical pit slopes of the outer mining limits aze established down to the shale bed, and there is room to accomplish this process. Backfilling of the pit slopes will utilize excess overburden salvaged during mining and weathered shale bedrock excavated from the base of the sand and gravel deposit to create a clay liner for the reservoir. The reclaimed shorelines for the reservoir ponds will slope at 3:1, beginning inwazd until the slope is ] 0 ft. below the maximum capacity for the designed reservoir water level, at which point a 2:1 grade will complete the slope to the reservoir/pit floor. The Reclamation Plan Map shows both a typical final configuration of the reservoir shorelines and cross-sections through the mined pit-slopes showing how the slopes will be backfilled to final grade. ASCI will incorporate additional backfill to create a more naturally appeazing undulating shoreline at the reclaimed site. The Reclamation Plan Map shows the typical undulating shorelines that will be created by final reclamation of the mining site. Topsoil will be spread evenly over all exposed, disturbed areas for plant- Speer Mining Rtsoura 14 October 7, 2002 Asphalt Specialties Company, Inc. DMG Permit Amendment No. 2
