`the road on the west side of the ridge will be shown on the revised ap resulting Ifrom physical survey of the site. TIMETABLES In order to accurately calculate the reclamation bond it is essential to define an exact maximum area that will be affected at any given time. The ffected land will include reclaimed lands that have not been fully released frorn reclamation liability, all active mining areas, and all roads, cutting areas, stora,g areas, etc., essential to the operation of the mine. Once it is determined how lar e of an area this will be, the entire affected area shall not exceed this size limitati n unless the permit is revised and the reclamation bond is increased to compe sate for this increase, or an area equal to the expansion has been fully released o any further reclamation liability. We respectively request the Division set financial warranty for 5 acres, or approximately 50% of the total area designated for extraction. At th time of the physical survey, a revised map will be submitted to the Division a d the exact nature and extent of responsibility for each area, and adjustments to t e total area will be submitted by Technical Revision. The revisions should no require an Amendment since they will not change the intcndcd reclamation pla or manner or method of mining. This is in tact the purpose of the GRID ystem, and subsequent adjustments should be allowable as a function of the req uired DMG Annual Report, and not via the Technical Revision process. The i itial change should occur through Technical Revision since substantial discussion f the nature and character of the existing disturbance will be discussed relative o finalizing the initial considerations for financial warranty. Since the grid system of identification will be implemented as a re ult of this conversion, all currently affected areas should be identified by both t e AL, ML, PL, or UL parcel along with the appropriate grid sector (i.e.: PL-8 ( uadrant B- 5)). This will aid in the transition to the grid system. The old areas of disturbance as defined, will have their actual acreage confirmed by physical survey and placement of survey established GRIDS, whit will vary from the original submittal, but once established by survey, will not c ange. All new disturbance will then be referenced to its GRID, and may includ reference to the older areas where determining financial warranty liability.
