Long <br /> Division Director <br />RE: Powderhorm Coal Company <br />2001 Aomual Subsidence Report <br />Roadside North amd South Portals Mime (C-1981-041) <br />Dear Mr. Stover: <br />The Division has received and reviewed the referenced report, dated October 3l, 2001.The report contains <br />photographs, narrative, and a mine map, which document completion of the required two pedestrian <br />surveys during 2001, and survey data which documents the two required surveys of subsidence monuments <br />during the year. The report fulfills the annual subsidence reporting requvement of the Powderhom permit. <br />Mining operations ceased in December, 1999, with no projected future mining. As such, the permit <br />requvement that subsidence pedestrian survey be conducted "over the next year's mining projections and <br />over the past two years of actual mining" and the requrement that survey of Jerry Creek and Coal Creek <br />subsidence monuments be conducted "...for two years subsequent to undermining" have been completed. <br />Therefore, the requirement for subsidence monitoring at Roadside Mine is suspended, unless miming <br />operations should resume, or unless the Division otherwise determines for good cause, that monitoring <br />should be resumed. <br />Please contact me if you have any questions. <br />Sincerely, <br />(,.u.( ~2.,~ <br />Dan T.
