• ~' /~ • <br />(f) Dimensions of any significant disturbance to the land surface. <br />I . Mining will start on the west end of the pit and move downstream, as well as into Currie Creek. <br />This plan will be continued until stream flow moves more sand into the original pit opening. <br />Excavation may then move back to that area. <br />2. There will be no mine benches, highwalls, impoundments or waste rock disposal azeas. The low <br />streambanks will be backsloped on both sides of the stream at 3H:1 V. <br />3. Stockpiles will be small - 5,000 T or less -and will only remain in place until they can be hauled. <br />(g) Dimension of any existing or proposed roads that will be used for the mining operation. <br />Lincoln County has a haul road east of County Road 109 leading to their pit and this continues as <br />a ranch road used by the owner. The road is approximately 20' - 25' in width for this low volume <br />operation. <br />(h) Water to be used in conjunction with the operation and source. <br />This will be a dry pit operation with no water requirements. <br />(i) Groundwater to be encountered and/or surface water intercepted. <br />This operation will limit mining on the stream floor from 4' - 5' in depth and will not intrude into <br />any groundwater. <br />(j) Compliance with applicable Colorado Water Laws and regulations governing injury to <br />existing water rights. <br />See (h) and (i) above. There will be no water rights to be affected. However, a Corps of Engineers <br />404 Permit will be acquired as other operations in the area have done. The applicant feels that <br />eliminates any need for a Stormwater Discharge Permit from the Colorado Water quality Control <br />Division. <br />(k) Refuse and acid-forming or toxic materials handled or exposed. <br />No refuse, acid-forming or toxic materials will be involved in this operation. It will be strictly a dry <br />pit operation with no chemicals required or no refuse generated. Sand and gravel are generally <br />considered to be chemically inert. <br />C-2 <br />
