FIIPP\ -(4 <br /> CROSSFIRE AGGREGRATE EXHIBIT E <br /> SERVICES.LLC <br /> Compliance with Reclamation Standards <br /> Please refer to maps in Exhibit F: Reclamation Plan Map. Most mining faces will be a vertical slope with <br /> soil stripped approximately 10 feet to the rear of the face. Excess fines may also be stored in stockpiles <br /> on the final floor of the pit until placed in final reclamation areas for backfill. All backfill will be placed as <br /> engineered fill and compacted to approximately 75 Proctor density or better as determined by a <br /> geotechnical engineer. <br /> Exterior perimeter faces of pits will be mined at a taper, backfilled,or left sufficiently distant from the <br /> permit boundary or buffer zone boundary, cut and fill to a 1V:2H slope or flatter or,where adjacent <br /> natural slopes are steeper than 1V:2H,to match adjacent slopes. There are some areas which will be <br /> left at a permanent slope of 1V:1H or vertical based on rock conditions as evaluated by an engineer at <br /> the time of mining and stabilized as necessary. Widths and heights will vary from area to area based on <br /> total depth of mining accomplished. All final slopes of 1V:2H or flatter will be covered with stockpiled <br /> top soil and re-vegetated to control erosion and prevent damage. <br /> Grading will be done so that erosion and sediment is controlled on affected lands and so that there is no <br /> damage to areas outside the mining area. Where highwalls of 1V:1H or steeper are left,temporary and <br /> permanent storm water management and erosion control features will be used on the uphill side as part <br /> of stabilization and reclamation. All slopes greater than 1V:2H will be located at least 50 feet from all <br /> exterior property boundaries to prevent property damage due to slope failure and to prevent potential <br /> slides or other damage on affected lands or outside the permit boundary. No mining disturbance or <br /> reclamation is planned within delineated floodplains. No surface discharge is planned. If surface <br /> discharge of water is necessary, detention basins, outfall armoring, and other techniques will be <br /> employed to prevent discharge of sediment. <br /> Some areas, such as those involved in the improvement of the access road,will be reclaimed <br /> immediately upon completion of work, however,for most of the affected area,the time between initial <br /> disturbance and final reclamation will be approximately two years based on the size of each phase and <br /> market fluctuations. The time to meet reclamation standards will vary. Backfilling,grading, and <br /> placement of soil should be accomplished within one year of completion of extraction of construction <br /> materials with seeding to follow as soon as possible based on the season and weather conditions. <br /> Refuse and Toxic Materials <br /> There is no reason to believe that toxic or toxic producing materials will be found or brought on-site, <br /> therefore, no special action is necessary to prevent leaching, protect the drainage system,or prevent <br /> unauthorized release of pollutants to surface water or groundwater beyond that necessary for erosion <br /> control and control of spills and leaks from vehicles and equipment. Fine grade material will be almost <br /> immediately moved to final locations for final reclamation. Normal municipal solid waste generated <br /> during operations will be hauled off-site for disposal and will not be buried or burned on-site. There <br /> may be some use of various wastes including wood waste, sawdust, bark and similar materials for <br /> reclamation to provide mulches,sediment control, and other purposes.
