intermittent in nature. Where surface cracking was observed, within a year the crack was <br />refilled with sediment from the creek channel. Minor ponding has also been observed to <br />have taken place in the subsided areas. This ponding was for a relatively short period and <br />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 are seven reservoirs in the Rapid Creek Basin, all outside the boundaries of the <br />permit area. The Bureau of Land Management has stated, and the Division agrees, that six <br />will not be affected by coal mining in the area. Cabin Reservoir, which is located outside <br />of the permit area, adjacent to the southeast corner of the South Portals mine plan area, <br />could possibly be impacted by subsidence if future mining were to occur within the <br />immediately adjacent portions of the permit area. 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 of permanent cessation of operations, and <br />the South Portals were sealed. Mine workings are 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 permittee 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 area. <br />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 are reported annually in the Annual Hydrologic <br />Report. Quantities consumed during active operations in water year 1992 were as follows: <br />Gallons Used <br />Domestic Water 1,397,000 <br />2,150,000 <br />Mine Water 3,350,000 <br />3,150,000 <br />750,000 <br />Highline Canal 1,170,000 <br />Location Used <br />Surface Facilities <br />Preparation Plant <br />Mining <br />Preparation Plant <br />Underground Roads <br />Surface Roads <br />The operator has shown appropriate documentation of right for water consumption. <br />Domestic water is supplied by Palisade Domestic Water. <br />Permit Revision No. 4 28 February 3, 2009
