I ~ EXECUTIVE SUMMARY <br />Seneca Coal Company (SCC) has prepared the accompanying information to <br />continue surface mining and reclamation operations at the Seneca II <br />Mine for the years 2002 through 2007. <br />The Seneca II Mine is operating currently under an existing permit, C- <br />80-005, which was issued by the Colorado Division of Minerals and <br />Geology (CDMG). The original permit was issued in 1981. Subsequent <br />renewals were approved in February 1987, February 1992, February 1997 <br />and February aooa; tha existing permit term extends until February <br />2007. <br /> She Seneca II Mine is located in Rou tt County, Colorado, approximately <br /> six miles southeast of the town of Hayden (see Figure 1-1). During its <br /> operational life, the mine produced approximately 1.5 million tons of <br /> bituminous coal annually. Production at the Seneca II Mine ceased in <br /> 1999, when all strippable coal reserves had been removed. Since the <br /> cessation of mining operations at Seneca II, SCC has continued <br /> production at the Seneca II-W and Yoast mine areas (see Figure 1-1). <br /> A11 of the coal from the Seneca II Mine, as well as the Seneca II-W and <br /> Yoast mines, is hauled by truck to the Hayden Station Power Plant. The <br /> power plant, owned by Xcel Energy, PacificCOrp and Salt River <br /> Agricultural improvement and Power District has one 168 megawatt (net) <br /> unit and one 250 megawatt (net) unit. Xcel Energy is the operating <br /> partner of the Hayden Station Power Plant. <br />The Seneca Mine, previous to 1968, operated north of Highway 40 and was <br />known at that time as Seneca I. Mining in the area that became the <br />Seneca II operations started in 1968. Since 1999, the Seneca IZ mine <br />has been completing mine disturbance reclamation in anticipation o£ <br />bond release. <br />The general type of mining utilized at Seneca II was the area surface <br />mining method. Some auger mining occurred during the late 1980s and <br />early 1990s. The typical mining sequence (Post 1979) began with the <br />removal of all suitable topsoil in a mining block prior to mining <br />disturbance. These soils were either stockpiled for future use or <br />TR-37 1-1 Revised 04/05 <br />
