• Introduction <br />Bowie Resources Limited acquired the Orchard Valley Mine from the Cyprus Orchard Valley Coal Corporation <br />in December 1994. Bowie Resources Limited was acquired by Bowie Resources, LLC in December 2003. <br />The underground coal mine (renamed the Bowie No. 1 Mine) is approximately two miles north of Paonia, <br />Colorado. The Bowie No. 1 East Mine has not operated since it was sealed in June 1986, following a mine <br />fire. The areal extent of the East Mine workings was 1,156 acres at that time. During July 1993, rehabilitation <br />efforts at the 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 the mine <br />remaining sealed and inactive. <br />The existing coal processing support facilities at the East mine were reactivated during 1993. The West mine <br />was opened in January 1987. The areal extent of the West mine at the end of 2009 remains unchanged and <br />is approximately 764 acres. The combined acreage of the East and West mines is approximately 1,920 acres. <br />The coal mined from both the East and West mine is in the "B" seam of the Mesaverde Coal Member. <br />Hydrologic monitoring began at the mine in 1983. This report presents monitoring results from the 2009 <br />monitoring season. <br />The Bowie No. 1 Mine has been idle for more than 10 complete monitoring seasons. Several monitoring <br />points are no longer available for monitoring due to a mechanical collapse of drill holes. Bowie No. 1 received <br />permission through a revision to the permit document (TR-34) to eliminate these holes from the monitoring <br />schedule. <br />The following 2009 Annual Hydrology Report narrative is divided into ten parts. Discussion is presented by <br />each monitoring category identified in Table 1 - Summary of Hydrologic Monitoring Stations - Required <br />Monitoring for Annual Hydrology Report. <br />• Table 1 (immediately following this narrative) defines the monitoring points bytype and sample frequency, field <br />parameter sampling schedule and laboratory parameter sampling schedule. Several monitoring points have <br />been removed from the surveillance schedule and are noted on this table as such. This table also lists the <br />NPDES monitoring points. Discharge monitoring reports, submitted to the DBMS quarterly, are incorporated <br />into this report by reference. <br />Table 2 contains a listing of the laboratory parameters for surface and ground water to be tested in <br />accordance with the mining permit application. Laboratory analyses are performed by ACZ Laboratories, Inc., <br />2773 Downhill Drive, Steamboat Springs, CO 80487 or by Enviro-Chem Analytical, Inc., 685 West Gunnison <br />Ave., Suite 108, Grand Junction, CO 81501. <br />Table 3 contains local precipitation data for the year. <br />Table 4 contains a listing of all monitoring points that have been undermined by the Bowie No. 1 Mine, the <br />date of mining, and the panel or section that undermined them. <br />Table 5 contains a listing of all monitoring points that are potentially impacted by the angle of draw of the <br />underground workings of the Bowie No. 1 Mine. Since the mine is currently idle, no prediction of potential <br />monitoring point impacts is presented. <br />Table 6 contains a listing of all actively monitored points, with descriptions of their locations and a reference to <br />the Monitoring Point Figure that contains this year's monitoring data. <br />Ponds were sampled for water quality when discharging or inflows/outflows were occurring. Ponds in the <br />permit area are typically spring-fed or seep-fed and exhibit diffuse non-concentrated areas of inflow. Often the <br />• pond outlets present the only point of concentrated flow at which flow measurements and field parameters can
