EXHIBIT 0-1 - WATER INFORMATION NARRATIVE (CONTINUED) • Surface Water System The proposed mining operation is located between the east bank of the South Platte River immediately upstream of the headgate to the Fulton Ditch. Portions of the property lies within the 100 year floodplain of the South Platte River. The area consists of irrigated and non-irrigated farmland. Irrigation water has been provided by alluvial wells on the property. These wells will be abandoned as a result of mining. The Bull Seep traverses the eastern portion of the property. This ditch drains surface water and spring water from the terraces to the east . The ditch empties into the Fulton Ditch approximately one mile northeast of the property. The drainage water from the property will be routed to sediment ponds created by the mining. No adverse impact to the surface water system is expected. Ground Water System A search of the State Engineer' s records was made to locate wells within one mile of the site . A map showing well locations is • included on EXHIBIT G-3 , WELL LOCATION MAP after this narrative . A tabulation of wells is included as Table G-1 at the end of this narrative. The wells in the area are used primarily for irrigation and domestic purposes . There are domestic wells within one mile of the site . The wells • withdraw water from the alluvium or the Denver Basin aquifers . The area is underlain by shales and sandstones of the Arapahoe aquifer. Mining operations are not expected to affect the underlying bedrock aquifer . Water level declines are not expected to occur as a result of mining. • Management of Runoff All of the runoff from stormwater will be channelled to remain within the mining area, and there is expected to be no affect on offsite property. A Stormwater Discharge Permit will be obtained prior to beginning of the operation. • • •
