There is <br />potential for continued erosion and incision of the channel and continued filling with eroded coal and shale fines into a <br />downstream pond, thus decreasing the ponds depth and capacity as a storm water retention facility. The site was brought <br />to the attention of DRMS's AML program that has since planned to repair the site. <br />A temporary road will need to be built to access the damaged channel. A portion of the access road, the pond and a small <br />portion of the damaged channel exist within the PSCM permit area. AML has agreed that all disturbed areas within the <br />existing permit boundary will be restored, including seeding with the approved seed mix as specified in the mining permit. <br />The AML group will also monitor the site following construction activities to ensure slope stability, revegetation success, <br />and to control noxious weeds in following years until the site is fully reclaimed. <br />If you have any questions or need additional information please contact me via email at scowman(a)peabodyenerty.com <br />or by phone at (970) 276 -7003. <br />B.
