• Introduction <br />Bowie Resources Limited acquired the Orchard Valley Mine from the Cyprus Orchazd Valley Coal Corporation in <br />December 1994. Bowie Resources Limited was acquired by Bowie Resources, LLC in December 2003. The <br />underground coal mine (renamed the Bowie No. 1 Mine) is approximately two miles north of Paonia, Colorado. The <br />Bowie No. 1 East Mine has not operated since it was sealed in June 1986, following a mine fire. The areal extent of the <br />East Mine workings was 1,156 acres at that time. During July 1493, rehabilitation efforts at the portal area of the East <br />mine were completed and the mine workings of the East and West mines were connected. Only the first fifteen crosscuts <br />of the East mine were reopened with the rest of the mine remaining sealed and inactive. <br />The existing coal processing support facilities at the East mine were reactivated during 1993. The West mine was opened <br />in January 1982 The areal extent of the West mine at the end of 2004 remains unchanged and is approximately 764 <br />acres. The combined acreage of the East and West mines is approximately 1,920 acres. The coal mined from both the <br />East and West mine is in the "D" seam of the Mesaverde Coal Member. Hydrologic monitoring began at the mine in <br />1983. This report presents monitoring results from the 2004 monitoring season. <br />The Bowie No. 1 Mine has been idle for more than 5 complete monitoring seasons. Several monitoring points aze no <br />longer available for monitoring due to a mechanical collapse of drill holes. Bowie No. 1 received pemrission through a <br />revision to the permit document (TR-34) to eliminate these holes from the monitoring schedule. <br />The following 2004 Annual Hydrology Report narrative is divided into [en 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 I (immediately following this narrative) defines the monitoring points by type and sample frequency, field <br />parameter sampling schedule and ]aboratoryparametersnmpling schedule. Several monitoring points have been removed <br />from the surveillance schedule and aze noted on this table as such. This table also lists the NPDES monitoring points. <br />Discharge monitoring reports, submitted to the DMG quarterly, are incorporated into this report by reference. <br />Table 2 contains a listing of the laboratory parameters for surface and ground water to be tested in accordance with the <br />mining pemrit application. Laboratory analyses are perfomred by ACZ Laboratories, Inc., 2773 Downhill Drive, <br />Steamboat Springs, CO 80487. <br />Table 3 contains local precipitation data for 2004 <br />Table 4 contains a listing of all monitoring points that have been undermined by the Bowie No. 1 Mine, the date of <br />nrining, and the panel or section that undemrined them. <br />Table 5 contains a listing of all monitoring points that aze potentially impacted by the angle of draw of the underground <br />workings of the Bowie No. 1 Mine. Since the mine is cuaently idle, no prediction ofpotential monitoring point impacts <br />is presented. <br />Table 6 contains a listing of all actively monitored points, with descriptions of their locations and a reference to the <br />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 permit azea aze <br />typically spring-fed orseep-fed and exhibit diffuse non-concentrated areas of inflow. Often the pond outlets present the <br />only point of concentrated flow at which flow measurements and field parameters can be obtained. Where possible, <br />quality measurements aze obtained at the pond inlet. Stagnant water in ponds was not sampled since water quality results <br />would show the effects of evaporation and stock use and could not be used to evaluate potential mine affects. <br />This report includes data collected specifically [o meet requirements of the Division of Minerals and Geology (DMG). <br />At the request of the DMG, minimum, maximum and average baseline data is now presented on each monitoring point <br />
