Deep Cut LLC - 22 West Pit Page 4 Adequacy response 01 Permit # M-2017-032 mention. Because there is no overburden or topsoil on the old Plant Site area there is none to save from this area. Map Exhibit F-1- Reclamation Plan Map (Option 2) shows how the plant site area would be reclaimed if no mining takes place on the pre-law dirt pile area. Note that the slopes into the lake are left as gravel and will be graded and sloped only. In the reclamation plan and in my response to item 15 of your adequacy letter I outline a second option for the Reclamation Plan which takes into account not mining the pre-law dirt pile area. In the initial plan, I outlined resoiling the slope around the lake in the old Plant Site area, but because there is none available now, they will not be resoiled. The soil or a usable growth medium is only available from the pre-law dirt pile in the northeast portion and this area will not be redisturbed during mining and reclamation, on the old Plant Site area. g. Please indicate on Exhibit C1 —Mining Plan Map any proposed setbacks for the operation, including from the ditch to the north, and from proposed permit boundaries. I have added a note to Exhibit C-1 — Mining Plan Maps listing the setbacks as 25 feet from the permit line as discussed on page 10 paragraph 5. 1 also added 2 lines to the map showing the top of slope JOS) line and the vertical mining setback line as shown on the cross section in the upper right-hand corner of the map. The south bank of the Aurora overflow ditch is a minimum of 80 feet north of the permit line, the Toe of Slope JOS) line is 25 feet south of the permit line and the vertical digline is 50 feet from the permit boundary. So at a minimum the distance from the mining limit to the ditch bank will be 105 feet. h. For any proposed affected land boundary corners that exist or will exist inside of a pond, please provide coordinates of latitude and longitude, and describe how the boundary corners will be delineated in the field. Only one corner will be located in the pond. Valco, Inc. had to do this during the partial release of the area south of this line from M-1977-560 to stay in compliance with the Division of Water Resources regulations governing pre/post lake surface area. The lake area south of the line was determined to be pre-1981 lake surface and the water area north of the line is post-1981. Ideally we would have drawn a single line from the east shore to the west shore and not had a midpoint. A line has been added to Maps Exhibit C-1 and C-2 that connects the permit corners located on the east and west banks and a dimension line showing the distance from this line to the corner is included. The coordinates for the 3 corners that make up this line were also added to the maps. The only way to physically mark this corner is to place some type of floating marker at that point. A surface marker is not practical and would be dangerous for the skiers and boaters using the lake. The operator has no plans to return to mining that part of the permit area in the future so therefore it is unlikely that the mine operations will disturb area south of a line drawn from the permit corner on the east bank where the permit line enters the lake and the permit corner on the west bank. This line is shown on both Mining Plan Maps (C-1 & C-2) for reference. Any disturbance south of this line, associated with mining or permit reclamation could potentially be considered a permit violation.
