I will be submitting revised permit pages to reflect most of your suggestions, but I <br />question one aspect of it. The rules on signs and markers (provided below) do not require that <br />perimeter markers be retained and maintained until after phase 3 bond release — that's only required <br />for mine I.D. signs (see highlight below). To keep markers maintained for 10 years on the upper side <br />of a backfilled, re- graded and revegetated road or bench cut on the side of a mountain (like all of the <br />West Elk Mine site), for instance, is very impractical and serves no purpose in ensuring that <br />equipment operators know "where they can and can't disturb ground" (per Ms Belka below.) As is <br />stated in Rule 4.02.4 the markers would be kept in place until the activities pertaining to the surface <br />operations or facilities (e.g. vent fan, stockpiling, etc.) cease — i.e. during the operation of those <br />facilities, but not after reclamation. As such, I am hesitant to commit to post - reclamation maintenance <br />of markers in our DRMS permit. <br />Thanks, <br />Kathy <br />"4.02.2 Mine and Permit Identification Signs. <br />(1) Identification signs shall be displayed at each entrance to the permit area <br />from public roads. <br />(2) Signs shall show the name, address, and telephone number of the <br />person who conducts the surface coal mining operations and the <br />identification number of the current hermit authorizing mining activities. <br />
