flows will constructed as part of phase 2 of mining. This ditch is located at the north <br />edge of phase 2 and is to be constructed at the commencement of phase 2 <br />operations. The drainage letter and supporting calculations provided to Weld <br />County are attached to this exhibit for reference. The stockpiles will be protected <br />from wind and water erosion with temporary seed cover if the piles are left in place <br />for more than 180 days or one growing season. The seed mix will be the dryland <br />pasture mix. See EXHIBIT E - Reclamation Plan 2(d) for the dryland pasture seed <br />mix and quantities. This temporary seeding for the stockpiles will be applied by <br />hydroseeding. After hydroseeding, fiber mulch will be applied by hydromulching <br />at a rate of one ton per acre. <br />(d) The overall maximum area of disturbance proposed is 17.5 acres. Approximately 3 <br />acres will be utilized for the access road, stockpile areas, and sediment ponds. The <br />remaining 14.5 acres of the 17.5 acres will be used for active mining. The <br />approximate dimensions of the active 14.5 acre mining block will be 1200 feet by <br />525 feet. The overall pit boundary and active mining phase boundary will be <br />clearly delineated at all times during operation. <br />(e) The amount of fill mined per year will depend on the economy and local demand <br />for these resources. It is not intended for the borrow pit to be an intermittent <br />operation; however, there may be periods of inactivity due to lack of demand for fill <br />in this area. The following is the anticipated timetable for the mining operation: <br />2010-2015 Mining & Reclamation of phase 1 <br />2015-2020 Mining & Reclamation of phase 2 <br />(f) According to the Custom Soil Resource Report for the Konig Borrow Pit from the <br />USDA Natural Resources Conservation Service, there is Ascalon fine sandy loam <br />and Avar fine sandy loam in this area. The maximum depth of the fill to be <br />excavated is 10 feet. <br />(g) The primary commodities to be mined are sandy loam fill dirt. The intended use is <br />for oil and gas facilities and associated roads, battery areas and drilling operations. <br />(h) There are no expected incidental products to be mined/extracted by the proposed <br />operation. <br />(i) Explosives will not be used in conjunction with the mining or reclamation.
