-B- In Bolton Draw, the most affected watershed, the calculated effects would severely overestimate probable effects. Areas of existing disturbance have already been reclaimed, or soon will be reclaimed. By the time anticipated future mining in this watershed is conducted, reclamation of existing disturbances will be complete, and the sediment control facilities will most likely have been removed. Surface Nater, Tipple Area No effects on the quantity of surface flow have been identified. Runoff from the permit area flows to a sediment pond before being released to the irrigation ditch at the north boundary of the property. Monitoring of pond effluent has not identified any of the water quality effects described for the minesite. During the original pennittin9 process, the effect of blowing coal dust on the surrounding wetlands was identified as a water quality concern. This concern resulted in the issuance of a stipulation to the original permit (See section V of this Document). The pe-mittee submitted the appropriate Information which alleviates this concern. The probable hydrologic consequences of mining to the local surface water regime are identified to be: 1. Degradation of water quality. The predominant ionic balance of water discharging from the affected area will likely be sodium-sulfate rather than the calcium-bicarbonate type water documented during baseline investigatldns; 2. Short-tend salt loading in the surrounding ephemeral drainages. This Impact will be a seasonal concern, as the salt loading potential 1s inversely proportional to streao discharge; 3. Temporary reductions of the quantity of rater flowing through the ephemeral drainages due to sediment ponds impounding natural hors. Ground Mater. Mine Site The Kerr Coal operation extracts the Sudduth Coal seas on the restern liob of the asymetrical Johnny Moore Syncline. The general area is faulted, and streams have incised themselves into these fault zones. The Sudduth Coal sub-crops under the strewn valleys. Three aquifers have been identified in the Kerr Coal permit application: alluvium associated with the ephemeral streams; upland terrace deposits; and the Sudduth Coal sego. The alluvial deposits associated rith the streams are located 1n narror bands parallel to the stream channel. These deposits consist of lenticular-sand, gravel and clay. The probable hydrologic consequence of mining near these alluvial bodies is a change 1n the chemical composition of the unconfined water in these deposits. The water type 1n the alluvium x111 mirror that of
