Box 2707 <br />Durango, CO 81302 <br />Dear Vic: <br />Pht~nelFar. (303)346-5196 <br />1~-i41ai1: tevvicki7l5asrhl.rom <br />RECEIVED <br />JUNG 3 2002 <br />Diuisian ei Minerals and Geology <br />I have met with Harry Ranney of the DMG and we have laid out the steps that need to <br />take place at the Carbon Junction Mine to avoid major regulatory problems with <br />reclamation. This letter outlines the steps that are needed: <br />1) Revise the Ewing Mesa gravel pit to absorb those areas of the coal mine that will <br />soon be released. These areas are a) the multi-use area, b) sediment pond #1, c) topsoil <br />stockpiles #3, #4 and #7, d) the south pit area. This revision will be considered a <br />permit amendment and will be treated similar to a new permit. The Ewing Mesa #2 110 <br />permit will also be absorbed into the main Ewing Mesa gravel permit for this <br />amendment. <br />2) Revise the Carbon Junction Mine Permit [o do the following: <br />- Add a very small area at the south boundary of the permit for the new Carbon <br />Junction channel to meet the existing drainage. <br />- Provide a new reclamation plan which shows revised post-mining topography and <br />cross-sections, <br />- Show updated hydrologic controls for the north pit, <br />- Design a permanent channel diversion for Carbon Junction drainage to the north part <br />of the permit area. This will create much more usable land for development in the heart <br />of the coal mine permit. <br />- Design a main culvert crossing for Carbon Junction drainage under the main access <br />road. <br />- Show that the following areas are to be released into the gravel pit: a) the multi-use <br />area, b) sediment pond #1, c) topsoil stockpiles #3, #4 and #7, d) the south pit area. <br />This is a significant advantage to the coal permit since the bond and future liability <br />will be greatly reduced. <br />3) Conduct a bond release request for those areas absorbed into the gravel pit. The <br />exact amount of this release is unknown at this time but it will be substantial. <br />
