<br />GENERAL NOTES

<br />2. Total Mined Land Area: 30.25 Acres
<br />Lcres es Northern Pond
<br />cres Southern Pond
<br />Permit Area: 34.34 Acres Mining Area es New Paved Access
<br />es Outlet Pipe InstallationJ
<br />es Buffer Area (Existing
<br />4. The top two to six inches of topsoil material sholl be stripped from
<br />mining area, stockpile areas, processing areas, and site haul roads. The
<br />topsoil shall be stockpiled in buffer areas adjacent to mining operations
<br />and used for site reclamation. Topsoil stockpiles in place for one year
<br />or more shall be seeded using the reclamation seed mix.
<br />5. Reclamation topsoil placement, mulching, seeding and fertilizing shall
<br />be performed as sand and gravel is mined from the permit area. See
<br />Reclamation plans for additional details.
<br />6. Mining for the sand and gravel will require the use of pumps to
<br />remove groundwater from the excavation pit` area. The dewatering
<br />operations will progress along with the mining operations as they move
<br />through the site. Groundwater will be pumped and discharged into
<br />settlement pond(s) prior to discharge off of the project site and into
<br />the 33 Road Drain ditch located along the project's west property line.
<br />The discharge points will be approved by the State of Colorado. The
<br />appnovaed discharge will be monitored prior to release, in accordance
<br />with State permit requirements.
<br />7. (Haul roods 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 shall be kept damp, covered,
<br />or chemically treated with magnesium chloride, as required, to control
<br />dust.
<br />8. Access to and from the mining operations shall be from the
<br />approved N01 access at 32 112 Road only.
<br />9. 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 crusher be located within 500 feet on a residential
<br />dwelling.
<br />10. All sand and gravel highwall mining located within 100' of the
<br />Permit Boundary shall be cut at a maximum 3:1 slope. This restriction
<br />has been placed to minimize the risk of slope failure.
<br />11. Mining for sand and gravel material is anticipated to require a
<br />total of 5 years to mine, deplete material stockpiles, and complete site
<br />reclamation work.
