wetland areas have been enlarged to reflect the fact that seasonally flooded depressions and not ponds will be constructed as a part of the final reclamation plan at this location. ~(~~ 14. On the Reclamation Plan Map #4 the south pit has a bottom elevation of 6630'. This elevation appears to be the same elevation noted on the pre-mining map in the same location. How is this possible if the area is to be mined of gravel ranging from 13' to 48' thick? As noted above, it is difFcult to read the contour intervals and elevation due to the map size. Please clarify this discrepancy. Response: The elevation of 6630' mentioned as occurring as the bottom elevation of the south pit is an error on the map, which was prepared showing the potential final elevations following the cessation of mining operations. For some unexplained reason, when we turned off the premining contour lines in AutoCAD, the elevational intervals remained. We had not observed this mistake and all of the premining elevations have been corrected on Map # 4, Tellier Gravel Pit -Reclamation Plan Map. The DMG is incorrect in suggesting that the thickness of the gravel ranges from 13 to 48 feet and averages 19.9 feet in thickness. Their statement comes from item 4. Thickness of Gravel to be Mined which states "the depth of gravel ranges from approximately 13 feet to upwards of 48 feet, and averages 19.9 in thickness." Due to confidentially reasons, the measurements for gravel thickness are not presented in this Permit Application and only generalized terms are used. The only place 48 feet is used in this Permit Application is to describe the "depth of gravel" and the average thickness of gravel is 19.9 feet. As a result of excavating approximately 20 feet of gravel, the elevations associated with the final reclamation should be dropped an equivalent amount. When we prepared our final reclamation contour map we assumed that across the entire mine site elevations would be approximately 20 feet lower than the preexisting elevations. This is why the term approximate original contour is used in mined land reclamation. In this vein, when the elevations found on Map # 2, Tellier Gravel Pit -Premining Conditions Map are compared with the proposed elevations found on Map # 4, Tellier Gravel Pit -Reclamation Plan Map, it can be observed that the elevations in the proposed mine pit area when reclaimed will be approximately 20 feet lower in elevation. Examination of the elevations shown on Map # 4, Tellier Gravel Pit -Reclamation Plan Map with the premining elevations found on Map 2, Tellier Gravel Pit -Premining Conditions Map shows that the existing elevation in the center of the Phase II pit near the middle of the 2010 year mining block averages 6622 feet in elevation. While the elevation off Map # 4, Tellier Gravel Pit -Reclamation Plan Map shows the elevation after mining to be approximately 6606 feet. 10
