INi%HKXTION Bowie Resources Limited acquired the Orchard Valley Mine from Cyprus Orohard 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 June, 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 cot~leted and the mine workings of the East and Whst mines were connected. Only the first approximately fifteen crosscuts of the East mine were reopened with the rest 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 approximately 591 acres. The combined acreage of the East and West mine workings at the close of 1994 was • approximately 1747 acres. The coal mined from both the East and West mines is the "D" seam of the Mesaverde Coal Mcanber. Hydrologic tronitoring was begun at the mines in 1983. This report presents ironitoring results from the 1994 monitoring season. The 1994 Annual Hydrology Report narrative following is divided into twelve parts. Discussion is presented in accordance with each ~ronitoring category identified in Table 1. Summary of Hvdrologic Monitoring Stations -Required Monitoring for Annual Hvdrology Report. Table 1 imr[ediately follows the narrative in this report and precedes the 1994 data summaries provided for each station. The individual station data sumrtreries are also ordered in accordance with Table 1. Maps depicting the locations of all hydrologic ironitoring 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 sampled for water quality only when discharge or outflow was occurring. Ponds in the permit area typically are spring-fed or seep-f~ and exhibit diffuse non-concentrated areas of inflaa. In many instances, the pond outlets present the only point of concentrated flow at which flora measurements and field parameters can be obtained. Where possible, quality measurements are obtained at the pond inlet. Stagnant water in ponds was not 1
