111 <br /> M-2001-001 Line Camp Pit Amendment#2 (Expansion) <br /> moisture content and assuming recirculation of water if washing material.This is less than 0.1 acre- <br /> feet water per acre per year(equal to 1.2 inches precipitation). <br /> 11. Water source (6.3.3.(h)): Obtain water from irrigation water rights owned by the landowner <br /> (through existing and additional dry up of irrigated pasture in the permit area)2 and from <br /> precipitation on the permit area.The water will be obtained from the ponds or Home Ditch. <br /> 12. Groundwater (6.3.3.(i)): Excavate into the alluvial aquifer of the Dolores River. Well draw-down for <br /> nearest wells (to south and southeast of current permit area) done for 2001 and 2012 applications: <br /> please refer to those applications. No known wells within 1,000 feet of expanded excavations. <br /> 13. Compliance with water law(6.3.3.(j)): Comply as discussed in items 11 and 12 above, <br /> 14. Refuse/acid/toxic materials(6.3.3.(k)): No refuse, acid-producing, or hazardous <br /> chemicals/substances are expected to be exposed during mining operations.All fuel, lubricant, <br /> coolant, and similar materials used by equipment on the Pit shall be stored with secondary <br /> containment, and in accordance with a site spill prevention and response plan. <br /> 15. Waste (6.3.3.(k)): Dispose of solid waste generated on-site at a permitted facility.This includes any <br /> petroleum-contaminated soil from releases or leaks.This site may accept clean fill (earth, crushed <br /> Portland cement concrete, cured asphaltic cement concrete,and rock)to process for aggregates <br /> and/or use for beneficial fill to achieve final grade.This site may accept logging debris (wood waste) <br /> to use as mulch/soil amendment in reclamation. <br /> 16. Hydrologic balance (6.3.3.(I)): Based on review of the terrain, water rights, irrigation, wells, and <br /> related information,the Pit is expected to have very minor impacts on the water balance in the <br /> immediate area or downstream on the Dolores River.See previous applications. <br /> 17. Prevention of off-site damage (6.3.3.(I)):The terrain, combined with the shallow nature of the <br /> proposed mining, and setbacks from adjacent private property to north and south,there is no <br /> significant potential for off-site damage to infrastructure, buildings and other structures, or users of <br /> those features. Impact of excavations and berms on stability of SH-145 was reviewed and reported <br /> in Attachment 1 to Exhibit S of the 2001 application and is still valid. No impact on roadway stability <br /> has been observed in 21 years of mining(2003-present). <br /> 18. Stability of terrain (6.3.3.(I)):As with item 17 above, slopes of 2H:1V or flatter are not expected to <br /> create problems with stability of the land within or outside the permit area.Although closer than <br /> current guidelines allow, the bank between the southeast corner(Pond#5) and the riverbed shows <br /> no indications of failure in the past ten years while Pond #5 has been excavated. Materials left in <br /> place meet or exceed requirements for"soil-rap" in current DRMS guidelines.All expansion <br /> excavation is more than 350 feet from OHWM of Dolores River. <br /> 19. Processing on-site (6.4.4.(m)): Process materials (crushing, screening, and possibly washing) on-site <br /> using portable plants located and operating intermittently on-site, with no permanent structures. <br /> Use no chemicals. Permit plants in accordance with Colorado air quality and other regulations. With <br /> County approval, and need by CDOT or other agencies, the site may host a hot-mix asphalt facility <br /> or ready-mixed concrete plant. In such a case, separate applications for such temporary use will be <br /> submitted, along with formal notification of DRMS. <br /> 20. Primary products (6.3.3.(n)): Produce aggregates (sand and gravel) borrow material (earth), and soil <br /> for use as construction materials. <br /> 21. Secondary products (6.3.3.(n)): no secondary products, unless earth and soil are considered such. <br /> 2 This will continue to follow the court-approved substitute water supply plan. <br /> 5182-22-001 WASTELINE, INC..
