Exhibit Page 17 <br />Prevention of unauthorized release of pollutants to surface water (3.1.5(10)) <br />The Applicant will handle mined material to be disposed of on-site in a way to prevent unauthorized release of <br />pollutants to surface water, and comply with this requirement. <br />Prevention of unauthorized release of pollutants to groundwater (3.1.5(11)) <br />The Applicant will handle material mined, handled, or disposed of on-site in a way to prevent unauthorized <br />release of pollutants to groundwater, and comply with this requirement. <br />General water hydrology and water quality (3.1.6(1)) <br />Hydrology and water quality issues are addressed at length in Exhibit G. The Applicant will comply with <br />applicable water and water rights laws and regulations, and water quality laws and regulations. No dredge or fill <br />in waters of Colorado or the United States is proposed, and no temporary or large siltation structures will he <br />placed except as required by permits, and will be removed in accordance with those permits. <br />Earth dams (3.1.8.(2)) <br />All post-reclamation ponds are incised. The reclaimed land service elevation will vary from 7230 down to 7213.5 <br />(above water level in the ponds), sloping from preexisting elevations at the permit boundary to areas (above <br />water level in the ponds) of up to twelve feet below the original ground level. The average unsubmerged ground <br />surface will be about four feet below the preexisting ground level. As material is available, a portion of <br />Stockpiles S3 and S4 [Figure D-3] (may be left as a permanent bens (with a reduced height and slope (not to <br />exceed 3H:1 ~ based on material available) on the south and southeast edges of the permit area as part of the <br />landscaping around the ponds. These stockpiles will have gaps to the original ground level to allow for water <br />flow in the floodplain and to prevent any potential for these to serve as embankments for water impoundment. <br />Erosion control (3.1.8.(3)) <br />All surfaces will be stabilized and protected to control erosion. Stockpiles of soil and excess fines will be seeded <br />(temporary seed mix) to stabilize the stockpiles against wind and water erosion. Stockpiles will also be <br />protected as necessary against erosion and traffic, and weed invasion. Because of the steep slope (1:1) as <br />proposed, polymers or other soil treatments will be applied to control erosion and improve conditions for <br />establishment of temporary grass cover. (See Exhibit J for seeding data, Exhibit D for stockpile information.) <br />Groundwater (3.1.7.) <br />The Applicant shall comply with all applicable statewide and classified standards, based on existing and <br />reasonably potential future uses, and with new standards which may be applicable in the future. (See Exhibit <br />G.) Based on information from other operations in the area with similar conditions, the operation is designed to <br />have no reasonable potential to adversely impact groundwater quality or quantity, or cause any further lowering <br />of quality. The Applicant will comply with any conditions as established by permits. <br />Wildlife safety and protection (3.1.8.(1)) <br />Wildlife issues are addressed at length in Exhibit H. A buffer zone will exist between the pit and major features <br />such as the highway (70 feet), river (200 feet), Line Camp (200 feet), and tree-line and fence to the south (400 <br />feet). This buffer zone will provide space for wildlife to migrate around the pit both up and down-river and across <br />the valley. Steeply-sloped berms will assist in detering wildlife and livestock from nearing the top of highwalls, <br />and temporary fencing will be used to reduce potential for livestock and wildlife to graze on areas under <br />reclamation or to enter through gaps in the berms. <br />Wildlife habitat management and creation (3.1.8.(2)) <br />In accordance with the wishes of the landowner, and based on planned post-reclamation use, no actions <br />specifically to create or improve wildlife habitat in the permit area shall be undertaken. <br />Topsoil (3.1.9.) <br />Approximately 24 inches of soil will be removed prior to extraction and stockpiled for protection (See discussion <br />in Exhibit D). Any woody vegetation will be removed. Due to the nature of the soil and the need to screen out <br />oversized rocks (cobbles), most of the material will be screened (either at the time of stockpiling or during <br />reclamation), with the undersized materials only treated and preserved as topsoil. (Refer to Exhibit 1 for detailed <br />information on topsoil.) Relocation of stockpiled topsoil will be minimized. First priority for topsoil placement will <br />be on those slopes which are above water level, at a depth of at least 12 inches; excess soil will be used for <br />Four States Aggregates, LLC 15 MAR 2001 <br />Application for Permit: Line Camp Pit M-2001-001 FSA-LCP-D2-001 <br />
