• 11Y120.AAA:S1lAV Bowie Resources r•;ro;ted acquired the Orchard Valley Mine from Cyprus Orchard Valley Coal Corporation in December 1994. The underground coal mine (renamed the Bowie No. 1 Mine) is located approximately two miles north of Paonia, Colorado. The Bowie No. 1 East Mine has not operated since it was sealed in Jure, 1986, following a mine fire. At that time the areal extent of the East mine workings was 1156 acres. During July 1993, rehabilitation efforts at the portal area of the East mine were conq~leted and the mine workings of the East and West mines were connected. Only the first approximately fifteen crosscuts of the East mine were reopened with the lest of the mine remaining sealed and inactive. The existing coal processing and support facilities at the East mine were reactivated during 1993 and are currently being utilized. The support facility at the West mine remains and is utilized for supplies and light maintenance activity, however, coal is now transported from the mine through the East portals. The West mine was opened in January, 1987. The areal extent of the West Mine at the end of 1994 was appznxi.n~ately 644 acres. The combined acreage of the East and West mine workings at the close of 1995 was • app*rYi+~tely 1800 acres. The coal mined from both the East and West mines is the "D" seam of the Mesaverde Coal t~5enber. Hydrologic monitoring was begun at the mines in 1983. This report presents monitoring results from the 1995 monitoring season. The 1995 Annual Hydrology Report narrative following is divided into eleven parts. Discussion is presented in accordance with each mronitoring category identified in Table 1. Summary of Hvdrologic Monitoring Stations -Required Monitoring for Annual Hvdrrology Resort. Table 1 immediately follows the narrative in this report and preeecles the 1995 data summaries provided for each station. The individual station data summaries are also ordered in accordance with Table 1. Maps depicting the locations of all hydrologic monitoring stations are appended to this report. Water quality monitoring includes field parameters (Table 2), water quality parameters (Table 3) and NPDES parameters (Table 4). Ponds were sanded for water quality only when discharge or outflow was occurring. Ponds in the permit area typically are spring-fed or seep-fed and exhibit diffuse non~oncentrated areas of inflow. In many instances, the . pond outlets present the only point of concentrated flow at which flora measuranents and field parameters can be obtained. where possible, quality measurarents are obtained at the pond inlet. Stagnant water in ponds was not 1
