Box 68 <br />Craig, CO 81626 <br />(970) 824-0173 <br />SUBJECT: FINAL EMPIRE SEALING OF F-SEAM WORKINGS AT #5 <br />PORTAL <br />The F-Seam workings at the Mine Portals near the Main Office and Warehouse(Shop <br />were permanently sealed according to the approved MSHA Ventilation Plan Addendum <br />dated July 24, 1997. The permanent seals are approximately 300 feet from the portals so <br />they could be built in a competent location. After the seals were constructed, rock and <br />dirt was pushed into the portals and then continued outside to form an angle of repose of <br />the material to prevent any unauthorized access. <br />Additional permanent seals were also constructed inside the SA Portals at the <br />Multipurpose Building area that completed the separation of the F-Seam Workings from <br />the E-Seam workings, except for the immediate access area. <br />The E-Seam workings, along with the remaining access area of the F-Seam at the #SA <br />Portal, were permanently sealed in the year of 2003. This was done in accordance with a <br />MSHA Ventilation Plan Addendum Dated October 24, 2002. <br />~' <br />R.
