• Adjacent Water Rights The SEO only lists 2 alluvial aquifer wells within 600 feet of the pit limit. Appendix G-1 is a copy of a print-out of permitted and/or decreed water wells in the vicinity of the Timnath property. Figure G-1 is a well location map with the permitted and/or decreed water wells within 600 feet of the dig limit. As required by the SEO, waiver agreements will be acquired from well owners within 600 feet of the pit. Once dewatering in the area has started, groundwater levels in the immediate vicinity are expected to drop. If water levels are dropping in adjacent wells, due to the dewatering of the Timnath Pit, such that well owners may be injured, Connell will begin to implement one or more the following measures. 1) Modify existing wells to operate under lower groundwater conditions. This would include re-drilling existing wells to deeper depths or lowering the pumps. All work would be done at Connell's expense with the exception of replacing equipment that was non-functional prior to mining. 2) If existing wells cannot be repaired, then Connell will drill a new well for the owner to replace the damaged well. The new well will produce water of the same quantity and quality. If the well has not been put to beneficial use prior to mining, Connell should have no responsibility to provide mitigation. Water Quality The proposed mining operation will not adversely impact water quality to either groundwater or surface water. The Colorado Department of Public Health will regulate all discharges from the site through an NPDES permit. The terms and conditions of the permit are anticipated to be those normally used in the Nationwide Permit system. A copy of the discharge permit will be supplied to DMG when it is issued. The proposed mining operation and aggregate plant do not use any chemicals or flocculent in the process. There is no reason for water quality monitoring to be required for the groundwater in the area. The proposed monitoring program for water table levels is adequate to protect the groundwater resources in the area. Wetlands A wetlands delineation was prepared for the applicant by Cedar Creek Associates, Inc. of Fort Collins. The delineation has been submitted to the Corps of Engineers and has subsequently been accepted. The mining operation avoids the majority of wetlands on the property. If a permit is required by the Corps of Engineers for the proposed operation, an application will be made. A copy of the permit will be given to the DMG once it has been issued.
