Total Project Area: 37.6 Acres 2. Total Mined Land Area: 32.5 Acres 3. Mining for sond and gravel will be accomplished by a progressive, open pit mining method. As overburden in front of the active sand and gravel mining area is removed, it will be placed in the backfill area behind the sand and grovel highwall area. The backfill area will also require inert, import fill material. AT NO TIME SHALL THE EXCAVATION PIT AREA (See Typical Section Depicted Below) EXCEED � 6 ACRES IN 4. The top two to six inches of topsoil material shall be stripped from mining area, stockpile areas, processing areas, and site houl roads. The topsoil shall be stockpiled in buffer areas adjacent to mining operations and used for site reclamation. Topsoil stockpiles in place for one year or more shall be seeded using the reclamation seed mix. 5. Reclamation topsoil placement, mulching, seeding and fertilizing may be delayed unit all sond and grovel has been mined from the permit area. See Reclamation plans for additional details. 6. Mining for the sond and gravel will require the use of pumps to remove groundwater from the excavation pit area. The dewatering operations will progress along with the mining operations as they move through the site. Groundwater will be pumped and discharged into settlement pond(s) prior to discharge off of the project site and into the Canning Factory Drain ditch. Two discharge points along the north boundary of the project, have been approved by the State of Colorado. The discharge will be monitored prior to release, in accordance with the permit requirements. 7. A 5' Landscape strip, installed per the City of Grand Junction Requirements, shall be provided along the entire length of the project along G Road and the north 600' of 23 Road. 8. The entire project site shall be fenced. A 6' chainlink fence with screening fabric shall be used in all areas which front 23 Road and G Road, and all residential uses. A high tension wire fence shall be used in all other areas. 9. All precipitation runoff shall be collected and retained in a new retention pond constructed along the west edge of the project. All disturbed areas within the project shall be graded such that drainage will be collected within this retention pond or the excavation pit area. 10. Haul roads depicted on this drawing may be adjusted or relocated as necessary to promote safe mining and access practices. Haul roads shall be covered with clean grovel as required to control dust. Houl roads, stockpiles, and other disturbed areas shall be kept damp, covered, or chemically treated with magnesium chloride, as required, to control dust. 11. Access to and from the mining operations shall be from 23 Road only. 12. Mining for sand and gravel shall not extend post the buffer limits established on the project drawings, unless otherwise noted. In no case shall the rock crusher be located within 500 feet on a residential dwelling. 13. All sand and grovel highwall mining (i.e. - the sand and gravel highwall) that is located within 100' of the North, South and West Permit Boundary shall be cut at a maximum 3:1 slope. This restriction has been placed to minimize the risk of slope failure large enough to cause damage to offsite structures. The 100' buffer length was established assuming a maximum mining depth of 32'. 14. Mining for sand and gravel material is anticipated to require 10 years to mine, and another 2 years to deplete material stockpiles and complete site reclamation work. slopes - - V �BOak 011ed k Cornpocted Remove E.blina Overburden D iAI Malerld At Replace W/ Pit Run Send - 'O't1-'b'- 8'l�t' -'-- 7 -Water Table and Govel. r� ?
