All auger-holes will <br />be backfilled on completion of drilling and sampling with cuttings and leveled. It should be noted that all minor <br />surface disturbance associated with the site geotechnical investigations falls within the footprint of the proposed <br />18LT Shaft Pad, and will be re-disturbed by subsequent pad construction activities. <br />This submittal includes revised PAP text, exhibits; and maps, addressing the location, nature, configuration, and <br />associated reclamation of areas affected by the proposed 18LT Shaft Pad geotechnical investigations. New and <br />revised PAP materials are identified by the attached Summary of Revisions/Additions. We would like to proceed <br />with this work as soon as possible, and therefore, appreciate your consideration and cooperation in facilitating <br />timely review and approval of this revision application. After you have opportunity to review the accompanying <br />information, please feel free to contact me with any questions or to discuss submittal materials or related matters. <br />Best regards, <br />Twentymile Coal Company <br />Jerry M.
