DRMS INTERNAL MEMORANDUM <br />DATE: May 6, 2008 <br />To: Marcia Talvitie <br />FROM: Dan Mathews <br />RE: Bowie No. 1 Mine (Permit No. C-1981-038) <br /> TR-48 (Reclamation Plan Revisions <br /> Initial Adequacy Response <br />Marcia, pursuant to your request, I have reviewed the above referenced TR-48 initial <br />adequacy review response, dated April 30, 2008, submitted by Jim Stover of J.E. Stover <br />& Associates, Inc. Items 1 through 11 of our initial adequacy letter were from my March <br />14, 2008 review memo to Joe Dudash. <br />Based on my review of the cover letter responses and associated page amendments, I <br />believe the submittal has adequately addressed all of the items with the exception of Item <br />#6 and Item #11. 1 have the following comments regarding these two items: <br />6. Narrative associated with this item in our original letter described the need for a <br />comprehensive listing of average topsoil replacement thickness for each logical <br />reclamation parcel. This was because the narrative regarding topsoil replacement <br />was scattered through various sections, different areas were apparently subject to <br />differing replacement depths, and there was a general lack of clarity. Our specific <br />request for revised information was probably not worded as clearly as it could <br />have been. The operator's response provided specific information related to areas <br />which have not yet been topsoiled, but will be topsoiled in the upcoming <br />reclamation project. The need for a comprehensive listing of soil replacement <br />thicknesses applicable to the various reclaimed areas throughout the mine site is <br />still warranted. A table keyed to a map or maps would probably be the most <br />concise way to present this information. <br />Please provide a comprehensive listing of the applicable average topsoil <br />replacement thickness for each logical reclamation parcel that has been or is <br />to be topsoiled.
