• • WATER RESOURCES <br />Exhibit G <br />Water Resources <br />This operation, being a bottomland gravel pit, will affect groundwater and to a very limited extent <br />surface water. Exhibit C-1 shows the location of the Lester-Attebury ditch that flows next to and just <br />outside the western edge of the permit boundary. This ditch will not be affected. Nor would it be affected as <br />the applicant as well as the landowner are the owners of the water in this ditch. <br />The aquifers in the area includes only the groundwater that flows through the gravels. The only <br />ocher known aquifer is in the Dakota Formation approximately 500 feet below the surface. No effect on <br />that aquifer will occur. <br />The mining plan provides details on dewatering operations. Those operations mill be conducted <br />under a NPDES permit. <br />Project water needs will be fully addressed in the Substitute Supply Plan co be filed with the Division <br />of Water Resources. That plan will address consumptive uses in processing the gravel, dust control, and <br />evaporative losses from exposed ground water. The plan also contains information on other matters <br />necessary for compliance with Senate Bill 120. <br />The only well in the area is adjacent to the farmhouse just outside of the permit boundary. This well <br />is a hand dug well about 17 to 20 feet deep. Because of the recharge system in operation at the Great Blue <br />Heron Pic site and the fact that all mining of this site will be downgradient from the well, there should be <br />little or no negative impact on the well. Besides that, the landowner for this operation owns the well. Please <br />refer to Exhibit S (Valuable Man-Made Structures) for further information on this issue. <br />Project water requirements for reclamation will be essentially none. Irrigation of the revegetation is <br />not anticipated, and even if done would need to be addressed in the Substitute Supply Plan and/or <br />Augmentation Plan. Other features of water resources deriving from reclamation will be addressed in the <br />adjudication process to be implemented after completion of the mining and reclamation, especially the <br />implementation of a recharge system similar to that in operation at the Great Blue Heron site. <br />Grisenti Farms Gravel Pit Original Application Exhibit G Page G-1 <br />
