COOLEY RESERVOII2 AND FULTON WILDER+E AREA PIT (Revised 07/09/99) EXHIBIT S -PERMANENT MAN-MADE STRUCTURES The purpose of this Exhibit is to specifically identify permanent man-made structures either off-site or on-site within the permit azea that are within 200' of any proposed mining. The following man- made structures are: Public Service Company of Colorado (PSCo.) -Transmission Towers A major transmission power line crosses the middle of both sides of the property between Parcels A and B on the east side of the river and between Parcels D-2 and D-3 on the west side of the river. In total there are 8 tower structures. The Slope Stability Analysis determined that a setback of 50'is adequate to ensure that these structures would not be impacted by mining. However, as the closest tower structures in Public Service's right-of- way boundary is 50'± and the minimum setback from any property line to excavation is 35', the nearest any excavation should come to any tower structure is 85'±, but no mining will occur within 200' of the PSCo. towers without an agreement to do so from PSCo. that is acceptable to the DMG. or acceptance by DMG of a revised Slope Stability Analysis proposing a lesser setback than 200'. /tem #7 - Sorenson's comment Fulton Ditch Company -Fulton Ditch, Spring Creek Seep Ditch, Headgate, Other Structures The Fulton Ditch is Parcels A's and B's east boundary. The Slope Stability Analysis determined that a setback of 50'is adequate to ensure that this structure would not be impacted by mining, but per comments from the DMG, the mining setback will be 65' from the inside top of the high bank of the Ditch. /tem #7 - Sorenson's comment The Spring Seep Ditch on Parcel A is located on the northeast side of a small internal access road within the property. Per the Slope Stability Analysis no mining would be allowed within 50' of this Ditch, but because of the location of this internal access road, the nearest any excavation should come to the Spring Creek Ditch on Parcel A is actually 75'+. The Spring Creek Ditch also abuts Parcel C-], but no mining is proposed on Parcel C-l. The headgate and other structures of the Fulton Ditch Company are within 200' of the permit boundaries, but no mining or disturbance is proposed within 200' of these structures.
