The monitoring well is to be used to determine if there is any significant disruptions of groundwater flows to the seep ditch. These features have been installed by the operator and there are no reports of adverse impacts at this time. The Division encourages the operator to continue with the hydrologic mo nicoring program and to keep the Division appraised of any results which may indicate a concern or significant impact on the water features in the immediate and surrounding area. 7. Mr. Krattenmaker indicated that Asphalt Paving Company has an interest in mining through the Lupton Bottoms ditch which occurs between the Phase 1 and Phase 2 areas. The current mining and reclamation plan does not allow for this feature to be "mined through.^ Therefore, such action will first require that the mining and reclamation plan be revised. It is likely that such action will require an amendment to the permit as this appears to constitute a significant change to the mining and reclamation plan. Mr. Krattenmaker indicated that Asphalt Paving Company is currently working out the details with the ditch company of how the normal ditch flows will be maintained in the event the ditch is removed via mining. The Division encourages the operator to consult with the local office of the U.S. Army Corps of Engineers to determine if specific wetlands and/or dredgelfill permits may be necessary. The Division is also willing to discuss with the operator how such a revision to the mine and reclamation plan can best be processed, ie: technical revision or permit amendment. 8. The reclamation cost for current and maximum expected disturbances was reevaluated. The Division has calculated a total cost of $95,000. (See attached reclamation cost). The $95,000 cost is based on a maximum overburden stockpile of 14,517 cubic yards that will be replaced over 3 stripped acres and a maximum of 2,500 linear feet of unfinished shoreline that will need to be graded from a 2:1 to a 3:1 slope. If additional overburden is needed to be backfilled and graded or if more than 2,500 linear feet of shoreline are left in an unfinished condition, then the reclamation cost will need to be readjusted. Since the operator has posted a financial warranty of 563,300, the financial warranty is not adequate to Complete the reclamation plan. Accordingly, the Division requests that the operator submit either a replacement warranty of $95,000 or a supplemental warranty of 31,700 within 60 days. As an alternative, the operator may revise the terms of the mining and reclamation plan via a technical revision and perform additional reclamation tasks to reduce the outstanding liability to $63,300 or less.
