2.05.6 -MITIGATION OF THE IMPACTS OF MINING OPERATIONS
<br />AIR POLLUTION CONTROL -PLAN
<br />An Air Pollution Control Permit has been listed in section 2.03.10 and is
<br />included as Appendix 2 (2) .
<br />FISH AND WILDLIFE PLAN
<br />Fish and Wildlife information is located in section 2.04.11 and also in
<br />Appendix 6. A raptor protection plan is on file with the Colorado Division of
<br />Reclamation, Mining 8v Safety. Section 2.05.4 details plants species to be included
<br />for replanting during reclamation procedures.
<br />PROTECTION OF HYDROLOGICAL BALANCE
<br />Information required by 2.05.6(3) concerning protection of hydrological
<br />balance is addressed in a report by Don May, P.E.,-which is included in Appendix
<br />11. See also Map King I-007 and Map King I-004.
<br />PERMANENT CHANNEL DESIGN
<br />In addition to the above mentioned report by Don May, P.E., a seed mix has
<br />been determined which will provide a suitable cover for the designed channel
<br />bottoms and sides. Composition and seeding rates of the seed mix are presented in
<br />Table 1. The desirable qualities of this vegetation include characteristics of high
<br />water tolerance, ability to withstand periodic inundation, sod-forming ability and
<br />deep=rooting characteristics. Soils were evaluated, and, during the period of
<br />vegetation establishment, should be able to resist erosion unless an event larger
<br />than the 10 year, 24 hour peak flow occurs. Any reseeding and channel
<br />maintenance- necessary during the period of vegetation establishment is recognized.
<br />The low cost and low maintenance benefits of the grassed waterway should result in
<br />a functional and desirable permanent channel configuration. The runoff
<br />calculations used in determining peak flow for the channel design are provided in
<br />Appendix 11 by Don R. May, P.E.
<br />National King Coal, LLC will monitor the structure during the vegetation
<br />phase and evaluate the need for any additional stabilization to ensure compliance
<br />with all applicable regulations.
