has disappeared. Monitoring indicates that little surface flow has been lost due to <br />subsidence in the Rapid Creek Basin. <br />3. Twenty-five springs have been located in the Rapid Creek Basin. All of these springs are <br />outside the subsidence angle of draw. None of the springs overlie present or planned <br />underground mine workings. Mining will not affect the natural springs. <br />4. There aze seven reservoirs in the Rapid Creek Basin, all outside the boundaries of the <br />permit azea. The Bureau of Land Management has stated, and the Division agrees, that six <br />will not be affected by coal mining in the azea. Cabin Reservoir, which is located outside <br />of the permit area, adjacent to the southeast comer of the South Portals mine plan azea, <br />could possibly be impacted by subsidence if future mining were to occur within the <br />immediately adjacent portions of the permit azea. However, coal extraction operations <br />were suspended in the South Portals mine area in January, 1997, and operations did not <br />resume. Subsequently, the operator filed notice ofpermanent cessation of operations, and <br />the South Portals were sealed. Mine workings aze separated by over a mile from the <br />reservoir, and no further mining is currently proposed. Consequently, there will be no <br />impact to Cabin Reservoir. <br />In the unlikely event that mining operations should resume, the perrnittee has committed on <br />page 20-10 of the permit application to modify the subsidence control and mitigation plan <br />as necessary, prior to resumption of operations within the South Portals mine azea. <br />5. Consumptive use of water at the Roadside Mine consists of domestic water used at the <br />surface facilities and preparation plant, mine water used at the preparation plant, applied to <br />underground roadways, and adsorbed to the coal and refuse, and water from the Highline <br />Canal used for dust suppression on surface roads. <br />Quantities of water consumed at the mine aze reported annually in the Annual Hydrologic <br />Report. Quantities consumed during active operations in water yeaz 1992 were as follows: <br />Gallons Used Location Used <br />Domestic Water 1,397,000 Surface Facilities <br />2,150,000 PrepazationPlant <br />Mine Water 3,350,000 Mining <br />3,150,000 PrepazationPlant <br />750,000 Underground Roads <br />Highline Canal 1,170,000 Surface Roads <br />The operator has shown appropriate documentation of right for water consumption. <br />Domestic water is supplied by Palisade Domestic Water. <br />Since cessation of mine and wash plant operations in 1999, water consumption has <br />declined dramatically, and is now limited to surface dust suppression associated with <br />reclamation operations (or loadout operations if the loadout is re-activated). <br />31 <br />
