Bowie Resources Limited <br />Bowie No. 1 Mine <br />e 1999 Annual Hydrology Report <br />Introduction <br />Bowie Resources Limited acqurred the Orchard Valley Mine from the Cyprus Orchazd Valley <br />Coal Corporation in December 1994. The underground coal mine (renamed the Bowie No. 1 <br />Mine) is approximately two miles north of Paonia, Colorado. The Bowie No. 1 East Mine has <br />not operated since it was sealed in June 1986, following a mine fire. The areal extent of the <br />East Mine workings was ],156 acres at that time. During Ju]y 1993, rehabilitation efforts at the <br />portal area of the East mine were completed and the mine workings of the East and West mines <br />were connected. Only the first fifteen crosscuts of the East mine were reopened with the rest of <br />the mine remaining sealed and inactive. The existing coal processing support facilities at the <br />East mine were reactivated during 1993. The West mine was opened in January 1987. The <br />areal extent of the West mine at the end of 1999 remains unchanged and is approximately 764 <br />acres. The combined acreage of the East and West mines is approximately 1,920 acres. The <br />coal mined from both the East and West mine is in the "D" seam of the Mesaverde Coal <br />Member. Hydrologic monitoring began at the mine in 1983. This report presents monitoring <br />results from the 1999 monitoring season. <br />The Bowie No. 1 Ivfine has now been idled for 2 complete monitoring seasons. Several <br />monitoring points are no longer available for monitoring due to a mechanical collapse of drill <br />holes. Bowie No. 1 has submitted a revision to the permit document to eliminate these holes <br />from the monitoring schedule. <br />The following 1999 Annual Hydrology Report narrative is divided into ten parts. Discussion is <br />presented by each monitoring category identified in Table 1 -Summary of Hydrologic <br />Monitoring Stations -Required Monitoring for Annual Hydrology Report. <br />Table 1 (immediately following this narrative) defines the monitoring points by type and sample <br />frequency, field parameter sampling schedule and laboratory parameter sampling schedule. <br />Several monitoring points have been removed from the surveillance schedule and aze noted on <br />this table as such. This table also shows small area exemptions and NPDES monitoring points. <br />Table 2 contains a listing of the laboratory parameters for surface and ground water to be tested <br />in accordance with the mining permit application. Laboratory analysis is performed by ACZ <br />Laboratories, Inc., 2773 Downhill Drive, Steamboat Springs, CO 80487. <br />Table 3 contains a listing of the field parameters and their application to the Springs, Streams, <br />Ponds and Wells within the permit boundary. Flow readings for springs and small streams are <br />reported in gallons per minute. Stream and River flows are reported in cubic feet per second. <br />Table 4 contains a listing of all actively monitored points, with descriptions of their locations <br />and a reference to the Monitoring Point Table that contains this year's monitoring data. Charts <br />(including historic data) are found in a separate section of this document, immediately following <br />the monitoring point tables. <br />Page 7 <br />
