reclamation needs by itself. Excess topsoil and sand will be used to augment the overburden in achieving the final grading shown in the reclamation map in Exhibit F. Overburden, topsoil, and sand will be used to backfill mining slopes to their final reclaimed state. Topsoil will be replaced on all disturbances outside of the ponds and on the pond slopes. It will not be replaced on the pond floor. Topsoil will be replaced in an average two-foot layer to restore the existing soil conditions. Details pertaining to reclamation can be found in Exhibit E and the maps in Exhibit F. 5. Site Access and Internal Road Improvements The Ewing Gravel Pit will be accessed from an existing gravel road in the south that connects to Fort Lupton and County Road 14 '/2. This road will require improvements such as widening, grading, and paving to support the gravel operation. Improvements to this road will be completed prior to the start of the mining operation. As the site has plans to be annexed into Fort Lupton, this road will facilitate access for the city after the mine has been reclaimed. There is a secondary property access to the site at the northeast of the property connecting to U.S. Highway 85. This access will not be used for regular mining traffic. The remainder of the site will be accessed internally. The ditch separating the upper and lower terraces has an existing crossing which is currently 15 feet wide. BURNCO plans to widen this crossing to facilitate access from the lower mining areas to the processing area. The crossing will be widened to 30 feet, and a box culvert will be inserted below to maintain flow through the ditch. Details of the crossing improvements are shown on Map C-2. This will be completed prior to the start of mining. The location and details of these items are all shown on Map C-2 in Exhibit C. Ewing Gravel Pit August 2023 D'4 Lewicki&Associates
