Lorettcito Canyon Deep Mine <br />Notice of Intent to Conduct Coal Exploration <br />Part II-Item 4 <br />The five sites proposed for exploration are located within the Lorencilo Canyon permit <br />azea south of Colorado State Highway 12, in'fowmship 34S and Range 66W. <br />The area is accessed by existing ranch roads and roads to numerous gas wells. A limited <br />number of new access roads are proposed for the project 'fhc existing and proposed <br />roads are shown on the map that accompanies this document. <br />The physiography of the area consists of moderate to steeply sloping canyons with <br />moderate to steeply sloping ridge lines. Interh~ittent or ephemeral str'eauts traverse the <br />area draining either southwest to northeast or west to east across the proposed project <br />area. The canyons are tributary to the Purgatoire River. Elevations range from <br />approximately 6900 to 7700 feet above mean sea level. <br />The stratigraphy in the area consists of the Raton Formation wtderlain by the Vermejo <br />Formations and the Trinidad Sandstone. All exploration operations will target the <br />minable coal seams present in the Raton Formation. <br />Vegetation in the area consists primarily of pinion pine, ponderosa pint and rocky <br />mountain juniper. The grasses and underbrush consist of Gambels oak, western wheal <br />grass, fringed sage, milkvetch, blue grama, and numerous other Iorbs and shrubs. <br />Part II-Item 5 <br />The method utilized for exploration is drilliug by rotary-air methods. Core drilling will <br />also be performed. Hole diameters will generally be 6 inches during chilling and 4 7/8 <br />inches while coring. Air is the preferred drilling medium, but if necessary, water may be <br />utilized. If water is utilized, the drill site will be stripped of topsoil and a water collection <br />pit excavated. Upon completion, the pit will be backfilled, topsoil respread, and the area <br />seeded. All chemicals will be biodegradable so as not to affect the surrounding area or <br />any groundwater which may be encountered. All drilliug will be performed utilizing a <br />truck mounted Gardener-Denver 1500 (or similar) type drill rig. <br />Access will be provided by the numerous roads that traverse the area. Existing roads will <br />be upgraded as necessary to accommodate the deployntcnt of the drill rig. Upgrades will <br />include rut removal and grading to facilitate drainage. Topsoil removal and culvert <br />installation are not anticipated. New roads will be limited to short spurs off from existing <br />roads to access drill sites. Spur roads constructed as part of this project will be reclaimed <br />upon completion of drilling. These roads will be constructed on grade to limit disturbance <br />and avoid cut and fill construction. If additional disturbance is required, topsoil will lust <br />be recovered and stockpiled. Where ever possible, drilling will be conducted along the <br />side of roadways thus minimizing disturbance. Site locations have been selected such <br />that no drill pads will need to be constructed. <br />
