<br />GENERAL NOTES
<br />1. Total Project Area. 37.6 Acres
<br />2. Tote, Mined Land Area: 32.5 Acres
<br />3. Mining for Bond and gravel will be accomplished by a progressive,
<br />open pit mining method. At overburden in front of the active sand and
<br />gravel mining area is removed, It wih be placed in the backfkl area
<br />behind the sand and gravel highwall area The backfGl area will also
<br />require Inert, import III material AT NO TIME SHALL THE EXCAVATION
<br />PIT AREA (See Typicd Section Depicted Below) EXCEED 3 ACRES IN
<br />TOTAL AREA. The 3 acre restriction has been placed on the excavation
<br />pit area to limit the amount of cite ill required for reclamation work to
<br />75.000 cubic yards.
<br />4. The top two to six inches of topsoil material sha!I be stripped from
<br />mining area, stockpile areas, processing areas, and site haul road, NOT
<br />TO EXCEED 15 ACRES IN SIZE AT ANY ONE TIME The topsoil shall be
<br />stockpiled in buffer aeas adjacent to mining operations and used for
<br />site reclanr►ation Topsor stockpiles in place for one year or more shall
<br />be seeded using the reclamation teed mix.
<br />5. Reclamation topsoi placement, mulching, seeding a"Id fertilizing may
<br />be delayed unit an amo not exceeding 10 acres In size at any one time,
<br />is available to work. See Reclamation plans for additional details
<br />6. Mining for the surd and gravel will require the use of pumps to
<br />remove groundwater tan the excavation pit area. The dewatering
<br />operations will progress along with the mt•ting operations as they move
<br />through the site Grwndwater wi!1 be pumped and discharged into
<br />settlement pond(s) prior to discharge off of the project site and Into the
<br />Canning Factory Drair ditch. Two discharge points along the north
<br />boundary of the project, have been approved by the State of Colorado
<br />The discharge will be monitored prior to release, In accordance with the
<br />permit requi-ements
<br />7. A 5' Landscape strip, Installed per the City of Grand Junction
<br />Requirements, shall be provided along the entire length of the project
<br />along G Road and the north 600' of 23 Road.
<br />8 The entire project site shall be fenced. A 6• chainlink fence with
<br />screening fabric shall be used in all areas which an 23 Road and G
<br />Road, and all residential uses. A high tension wire fence shall be used
<br />in al; other areas.
<br />9 All precipitation runoff shall be collected and retained in a new
<br />retention pond constructed along the west edge of the project All
<br />disturbed areas within the project shall be graded such that drainage will
<br />be collected within this retention pond or the excavation pit area
<br />10. Haul roads depicted on this drawing may be adjusted or relocated
<br />as necessary to promote safe mining and access practices Haul roads
<br />shall be covered with clean grovel as required to control dust Haul
<br />roads, stockpiles, and other disturbed areas sho'I be kept damp, covered,
<br />or chemically treated with magnesium chloride, as required, to control
<br />dust.
<br />11 Access to and t•om the mining operations shall be from 23 Road
<br />only
<br />12. Mining for sand and gravel shall not extend past the buffer limits
<br />established on the project drawings, unless otherwise noted. In no case
<br />shall the rock cxrushtr" located within 500 feet on a residential
<br />dwelling
<br />13 All sand and gravel highwall mining (le — the sand and grovel
<br />highwall) that is located within 100' of the North. South and West Permit
<br />Boundary shall be cu! at a maximum 3:1 slope. This restriction has
<br />been placed to minimize the risk of slope failure large enough to cause
<br />damage to offelte structures The 100' buffer length was established
<br />assuming a maximum mining depth of 32'
<br />14 Mining for sand and gravel material Is anticipated to require 10
<br />years to mine, and another 2 years to deplete material stockpiles and
<br />complete site reclamation work
