Bowie Resources Limited Bowie No. 1 Mine 1998 Annual Hydrology Report _ _. Introduction Bowie Resources Limited acquired the Orchazd Valley Mine from the Cyprus Orchazd Valley Coal Corporation in December 1994. The underground coal mine (renamed the Bowie No. 1 Mine) is approximately two miles north of Paonia, Colorado. The Bowie No. 1 East Mine has not operated since it was sealed in June 1986, following a mine fire. The azeal extent of the East Mine workings was 1,156 acres at that time. During July 1993, rehabilitation efforts at the portal area ofthe East mine were completed and the mine workings of the East and West mines were connected. Only the first fifteen crosscuts of the East mine were reopened with the rest of the mine remaining sealed and inactive. The existing coal processing support ficilities at the East mine were reactivated during 1993. The West mine was opened in January 1987. The azeal extent of the West mine at the end of 1998 is approximately 764 acres. The combined acreage of the East and West mines is approximately 1,920 acres. The coal mined from both the East and West mine is in the "D" seam of the Mesaverde Coal Member. Hydrologic monitoring began at the mine in 1983. This report presents monitoring resuhs from the 1998 monitoring season. The following 1998 Annual Hydrology Report narrative is divided into ten parts. Discussion is presented by each monitoring category identified in Table 1 - Suntntary of Hydrologic Monitoring Stations -Required Monitoring for Annual Hydrology Report. . Table 1 (immediately following this narrative) defines the monitoring points by type and sample frequency, field parameter sampling schedule and laboratory pazam~eter sampling schedule. Several monitoring points have been removed from the surveillance schedule and aze noted on this table as such. This table also shows small area exemptions and NPDES monitoring points. Table 2 contains a listing of the laboratory parameters for surface and ground water to be tested in accordance with the mining permit application. Laboratory analysis is performed by ACZ Laboratories, Inc., 2773 Downhill Drive, Steamboat Springs, CO 80487. Table 3 contains a listing of the field parameters and their application to the Springs, Streams, Ponds and Wells within the permit boundary. Flow readings for springs and small streams are reported in gallons per minute. Stream and River flows aze reported in cubic feet per second. Table 4 contains a listing of all monitoring points, with descriptions of their locations and a reference to the Monitoring Point Table that contains this yeaz's monitoring data. Charts (including historic data) aze found immediately adjacent to their respective monitoring point table. Table 5 contains local precipitation data for 1998. This data is obtained from the intemet at www.crh.noaa.gov/gjt. Table 6 contains a listing of all monitoring points that have been undermined by the Bowie No. ~t
