The fallowing year ;Johnson further descn"bed the <br />geology of the Mimiesota Creek area in USBM Technical Paper 721. More recently, in <br />1989, C. R Dunnrd compiled a coal resourtires map of the legion (USGS Map C-115). 1n <br />1998 the Colorado Geological Survey published, "Availability of Coal Resources in <br />Colo~xado: Somerset Quadrangle, West-Cenhal Coronado (CGS Resouroe Series 3~". <br />The general sttarigrrphy of the area consists of members of the Mesa Verde Formation of <br />the Upper Cretaceous System underlying the Wasatch Foanation of Tertiaoty Age. The <br />Borten Member of ttre Mesa Verde fo~on crops out lowest in the area with the <br />overlying Ohio Crete member exposed along many of the steeper slopes. Above the <br />Mesa Verde, rocks of the Wasatch Fozmation are exposed. The Upper and Lpw-er Coal <br />Members of the Mesa Verde Fonnatian are the major coal-bearing units in the area. The <br />A (King), B (Somerset), and C (Bear) coal beds of the Lower Coal Member and the D <br />(Oliver), E (Hawks Nest), and the F-Seam coal beds of the Upper Coal Member have all <br />peen mined within the North Fork Valley. <br />G~eral dip in area of the methane drainage pmject drilling is 3 fA 4 degrees to the <br />northeast Shatigraplric displacements and faults are lviown to occia in West Elk Mine. <br />Known geologic data does not indicate that these faults are locatable on the surface. <br />WATER RESOURCES <br />The town of Paonia is situated about 10 miles west of the area and receives an average of <br />approximately 15 inches of precipitation anmrally. Crivea drat precipitaiion increases as <br />elevation increases, the anneal preeipitaiion at the proposed well sites would be expected <br />fp be somewhat higher than that received at Paonia. Aa estimated 75% of the annual <br />precipitation occurs during Late winter and early spring„ mostly as snawfaIl. Tune, July, <br />and August ate oRen the driest months. <br />Drainage from the well pad for the proposed project primarily enters as unnamed <br />tributary of Deep Creek that is tnbutary W Raven Creek and is tributary to the North Fork <br />of the Gunnison River. No riparian, wetland or stream habitat will be affected by drilling <br />activities. <br />The alternate sediment controls used for these drill pads will consist of a slash, silt fence <br />or straw wattles placed vn the out slopes of the pad. The demonstrations that the <br />altema6ve sediment control measures meet the limitations of Rule 4.052 and 4.05.5 ate <br />remained in the attached SEDCAD results that were run for 1.0 acre typical pad site. <br />these calculations are in TR-101 and other previously submitted docimnenis. <br />
