EXHIBIT G—Water Information I. The proposed operation is not expected to directly affect the surface and ground water resources in and around the proposed permit area. The proposed permit area has no stock ponds, streams, ditches or reservoirs, which receive drainage and/or runoff from storm events. 2. According to the Colorado Division of Water Quality, Groundwater Information Desk, the recorded groundwater elevations in the vicinity of the proposed permit area is at 76 feet BGL in a 100 foot deep well located in the NW 1/4, NW I/4 of Section 26,(water level at approximately 7844 AMSL, well located 2250 feet NW of proposed permit area) and at 120 feet BGL in a 140 foot deep well located in the NE IM,NE 1/4 of Section 27. These upgrade groundwater levelsielevations would indicate that mining operations to an approximate elevation of 7855 feet AMSL would not encounter groundwater and the pit v,ill be a dry pit operation with no effect on water rights, drainage, or the hydrology of the area. The proposed permit area has no stock ponds, streams,ditches or reservoirs, which receive drainage and/or runoff from storm events. 3. Contract crushing operators will supply their own water needs from their own offsite sources. Owner/applicant's project water requirements would be for dust suppression on ramps and haul road areas during loading and hauling activities. An estimated maximum daily volume of 1000 to 3000 gallons would be required for dust control during these activities. If loading and hauling operations take place for I80 days per year then an estimated 360,000 gallons of offsite water may be required. It is likely that the actual number of days requiring water for dust suppression during hauling operations will be less than 180 days. 4. There are no sources of water for project requirements available within the proposed pennit area. The applicant/owner has sufficient water rights in other parts of the San Luis Valley and will supply water via tanker truck from offsite sources. 5. A National Pollutant Discharge Elimination System (NPDES)permit from the Water Quality Control Division at the Colorado Department of Health is not necessary for this permit application, however, a General Permit Application for Stormwater Discharges Associated with Sand and Gravel Production Operations(Permit No. COG-501207)has been applied for.
