0 0 Exhibit G - Water Information The operation is expected to have minimal impact on both surface and groundwater systems beyond what historically exists at the site. The operations will create a rangeland/ recreation area and possibly residential sites upon final reclamation. As noted in Exhibit D, the site has been mined intermittenly since about the 1940's; the depth of the workings have been relatively shallow. The elevation of the water table fluctuates seasonally. According to the previous landowner, the elevation of the water generally reaches its lowest point during the months of February, March, April and May, and to its maximum rise-- to approximately ± four feet below the ground surface -- during the summer months. The maximum rise in the elevation of the groundwater appears to follow spring runoff and the irrigation of surrounding pasture lands. It is planned that the pit will be mined primarily during the months of March through September, with some year round work and that the pit will be wet mined when possible. Depending on the maximum depth to be ultimately mined ( anticipated to be about t 12 feet ) water may be encountered. If water is encountered, the proper permits will be applied for and plans provided for the final useage of the water. An irrigation ditch was shown to cross the eastern portion of the original mining area of the gravel pit. As shown before, the ditch is no longer within the permitted area. There are some probable wetlands located near the gravel pit operations. These areas have been reviewed by the Army Corps of Engineers and it was determined that the areas were non-jurisdictional due to the fact that mining will remain out of the areas in question by a distance of at least 50'. A copy of their letter is attached. Hearing on Permit No. M-1987-038 Bayfield Pit No. 1
