EXHIBIT G <br /> WATER INFORMATION <br /> The proposed operation will have temporary impacts on both surface and groundwater in the <br /> local area. The mining and reclamation plan is designed to minimize the extent of these impacts. <br /> The operator has proposed adequate mitigation to address these impacts. <br /> Surface Water <br /> The mining operation is adjacent to the Boxelder Ditch as shown on Exhibit C. The operator <br /> owns four shares of this ditch. The proposed mining plan will relocate a 2,450 foot long reach of <br /> the ditch around the east side of the property. The relocation will allow for efficient extraction of <br /> gravel and will be done to maintain hydraulic conveyance of the ditch at historic levels. <br /> Additional benefits to the ditch would be derived from a reduction of seepage losses in this <br /> reach. The proposed plan will require the approval of the Ditch Company. Final engineering <br /> plans and a letter of approval will be provided to DMG once they are received. <br /> I <br /> The property is located in the floodplain of the Poudre River. The proposed mining operation <br /> will use best management practices during mining to minimize any potential impacts on the <br /> floodplain. This will be documented in a floodplain use permit that is issued by Larimer County <br /> as a part of their review. The reclamation plan proposes the construction of at grade lined <br /> reservoir storage. This use will have no adverse impact on the floodplain and will potentially <br /> offer some temporary storage during floods that would reduce downstream impacts. <br /> Appendix G-1 contains data obtained from the State Engineers office for all known water rights <br /> and well permits located in the area. All well permits and decreed wells are numbered and <br /> correspond to the locations of wells shown on Figure G-1. The locations for the wells are based <br /> on the State Engineers information and are not based on actual field locations. <br /> The project lies in the valley fill deposit of the Cache La Poudre River. This is an alluvial <br /> aquifer that is unconfined and consists of the sand and gravel that is being mined. The limits of <br /> the aquifer correspond roughly to the limits of the floodplain. The depth of the aquifer ranges <br /> from approximately 10' to 20' depending on the conformation of the underlying bedrock. It is <br /> estimated that bedrock lies between 15' to 25' below the proposed mining site. <br /> The underlying bedrock is the Pierre Shale Formation, which is a claystone—siltstone formation <br /> that is several hundred feet thick. This formation is almost totally impermeable. There are no <br /> known intrusions into the formation on this property. The upper three feet is weathered and has <br /> some minor fracturing. The unweathered shale is competent as a seepage barrier. The Pierre <br /> Shale can be inconsistent in quality for reservoir lining and is usually mixed with clay <br /> overburdens in the construction of a lined reservoir. There are some reservoirs that do not use <br /> any shale and rely totally on the clay overburden in the area for a liner material. This can work <br /> effectively if the material has sufficient fines. The Wellington Downs property that lies <br />
