• Introduction <br />Bowie Resources Limited acquired the Orchard Valley Mine from the Cyprus Orchard Valley Coa] Corporation in <br />December ] 994. The underground coal mine (renamed the Bowie No. ]Mine) is approximately two miles north of <br />Paonia, Colorado. The Bowie No. 1 East Mine has not operated since it was sealed in June 1986, following a mine Fire. <br />The areal extent of the East Mine workings was ],156 acres at that time. During July 1993, rehabilitation efforts at the <br />portal area of the East mine were completed and fhe mine workings of the East and West mines were connected. Only <br />the first fifteen crosscuts of the East mine were reopened with the rest of the mine remaining sealed and inactive. <br />The existing coal processing support facilities at [he Eas[ mine were reactivated during 1993. The West mine was <br />opened in January 1987. The areal extent of [he West mine a[ the end of2002 remains unchanged and is approximately <br />764 acres. The combined acreage of the East and West mines is approximately 1,920 acres. The coal mined from both <br />the Eas[ and West mine is in the "D" seam ofthe Mesaverde Coal Member. Hydrologic monitoring began at the mine <br />in 1983. This report presents monitoring results from the 2002 monitoring season. <br />The Bowie No. 1 Mine has now been idled for 5 complete monitoring seasons. Several monitoring points are no longer <br />available for monitoring due to a mechanical collapse of drill holes. $owie No. 1 received permission through a <br />revision to the permit document (TR-34) to eliminate these holes from the monitoring schedule. <br />The following 2002 Annual Hydrology Report narrative is divided into ten parts. Discussion is presented by each <br />monitoring category identified in Table 1 -Summary of Hydrologic Monitoring Stations -Required Monitoring for <br />Annual Hydrology Report. <br />Table 1 (immediately following this nanrative) defines the monitoring points by type and sample frequency, field <br />parameter sampling schedule and laboratory parameter sampling schedule. Several monitoring points have been <br />removed from the surveillance schedule and are noted on this table as such. This table also shows small area <br />exemptions and NPDES monitoring points. <br />Table 2 contains a listing of the laboratory parameters for surface and ground water to be tested in accordance with the <br />mining perrni[ application. Laboratory analysis is performed by ACZ Laboratories, Inc., 2773 Downhill Drive, <br />Steamboat Springs, CO 80487. <br />Table 3 contains a listing of the field parameters and their application to the Springs, Streams, Ponds and Wells within <br />the permit boundary. Flow readings for springs and small streams are reported in gallons per minute. Stream and River <br />flows are reported in cubic feet per second. <br />Table 4 contains a listing of all actively monitored points, with descriptions of their locations and a reference to the <br />Monitoring Point Table that contains this yeaz's monitoring data. Charts (including historic data) are found in a separate <br />section of this document, immediately following the monitoring point tables. <br />Table 5 contains local precipitation data for 2005. <br />Table 6 contains a listing of dischazges from all monitoring points that exhibited flows during the 2002 monitoring <br />season, presented by quarter. <br />Table 7 contains a listing of all monitoring points that have been undermined by the Bowie No, 1 Mine, the date of <br />mining, and the panel or section that undermined them. <br />Table 8 contains a listing of all monitoring points that are potentially impacted by the angle of draw of the underground <br />workings ofthe Bowie No. 1 Mine. Since the mine is currently idle, no prediction ofpotential monitoring point impacts <br />is presented. <br />Table 9 contains a listing of Monitoring Point Tables included with this report <br />. Table 10 contains a listing of Monitoring Point charts included with this report <br />
