Please sefer to attachmern A. <br />Mining operations are as indicated in attachment B. The crusher and processing <br />operation remains in this area on top of deposits yet to be mined. <br />Temputary wetlands continue to flourish in the southeast portion of the property as <br />shown. Expansion of these wetlands has occurred to the west Portiotrs of these wetlands <br />may remain permanent dependent upon post mining water levels. <br />Backfilling has occurred on the north, east, and south sides of the previous mined area. <br />Prior to backfilting, a trench was excavated into shale and backfilled with clay type <br />overbwden. Subsequent backfil! has been placed in compacted layers to create a barrier <br />to prevent water fmm infiltrating into the pit in order to reduce the efrect, if any, on <br />adjoining water table. It has reduced ow necessary pumping considerably. These sloped <br />areas have been topsoiled and reseeded. <br />2(101 and futwe mining will continue west of Phase lA. Based on market conditions and <br />remaining material yet to be cleaned up when the processing operation is moved into this <br />area; area disturbed will be approximately five acres. <br />Sincerely, <br />'^'- <br />Dan Kehn <br />Encloswes <br />6550 So.
