The existing access road may be altered during the reclamation of the shop and office areas, but this <br />is not currently planned. An access road will remain after reclamation to facilitate site access for <br />monitoring. The Atlas waste pile access road will remain as well. <br />19. Mine Water - Post Mine Plan <br />The mine water will be moved from the current mine pond to a permanent perforated pipe buried in <br />the waste rock, as part of the mine plan. This pipe will be left in place following reclamation. It <br />should easily be stable since the water will travel through the porous waste rock. The slope stability <br />of this design is discussed in Exhibit U. <br />20. Post - Reclamation Site Drainage <br />The entire site will drain to Sneffels Creek, as it has done historically. Diversion structures uphill of <br />the disturbed areas will be left in place permanently to reduce any erosion on the topsoiled areas. <br />These diversions have been designed for an event over 100 years in frequency. These diversion <br />structures may fill naturally over time, but by that point the vegetation on disturbed areas will be <br />well established. Debris that may enter the top of the piles after the ditches have filled will naturally <br />occur anyway and should not affect the piles in any way. As is seen in the final slope cross sections <br />of Map C -6, the top of the piles are mildly sloped and future long term debris will fill over the top <br />of the piles and will revegetate naturally, just as it does over thousands of years in the undisturbed <br />areas. Collection ditches installed during mining will be reclaimed once vegetation has established <br />on the areas of the Revenue that have been topsoiled and seeded. The sediment ponds will remain <br />in place until the collection ditches are reclaimed <br />The potential effect of future debris flows on the post -mine reclaimed site is discussed in Exhibit T. <br />21. Weed Control <br />Appropriate measures will be employed to minimize the occurrence and spread of noxious weed <br />species. The Weed Control Plan for the site will include: <br />1) A weed survey will be made of the permit area each spring in April or May. <br />Revenue Mine August 2012 E -8 <br />
