<br />• <br />• <br />2.05.6 page 1 <br />AIR POLLUTION CONTROL PLAN <br />An Air Pollution Control Permit has been listed in section 2.03.10 and is included in Appendix <br />2. <br />FISH AND WILDLIFE PLAN <br />Fish and Wildlife information is located in section 2.04.11 and also in Appendix 6. A raptor <br />protection plan is on file with the Colorado Division of Minerals and Geology. Section 2.05.4 details <br />plants species to be included for replanting during reclamation procedures. <br />PROTECTION OF HYDROLOGICAL BALANCE <br />Information required by 2.05.6(3) concerning protection of hydrological balance is addressed in <br />a report by Don May, P.E., which is included in Appendix 8. See also Map C-4, Map C-7 and Map C- <br />9. <br />PERMANENT CHANNEL DESIGN <br />In addition to the above mentioned report by Don May, P.E., a seed mix has been determined <br />which will provide a suitable cover for the designed channel bottoms and. sides. Composition and <br />seeding rates of the seed mix are presented in Table I. The desirable qualities of this vegetation <br />include characteristics of high water tolerance, ability to withstand periodic inundation, sod-forming <br />ability and deep-rooting characteristics. Soils were evaluated, and,. during the period of vegetation <br />establishment, should be able to resist erosion unless an event larger than the ]0 year, 24 hour peak <br />flow occurs. Any reseeding and channel maintenance necessary during the period of vegetation <br />establishment is recognized. The low cost and low maintenance benefits of the grassed waterway <br />should result in a functional and desirable permanent channel configuration. The runoff calculations <br />used in determining peak flow for the channel design are provided in Appendix 8 by Don R. May, P.E.. <br />National King Coal, LLC will monitor the sttucture during the vegetation phase and evaluate <br />the need for any additional stabilization to ensure compliance with all applicable regulations. <br /> Table 1.
