<br />INTRODUCTION <br />The 2007 Annual Hydrology Report for the Bear Coal Company, Inc., Bear No. 3 <br />Mine is hereby submitted in accordance with the rules and regulations of the Division of <br />Reclamation, Mining & Safety. <br />The Bear No. 3 Mine is owned and operated by Bear Coal Company, Inc. The <br />mine is located along the North Fork of the Gunnison River approximately one quarter <br />mile east of Somerset, Colorado, along Colorado State Highway 133. <br />The Bear No. 3 Mine ceased all coal production on November 13, 1996 and the <br />portals were sealed in January 1997. During 1997 reclamation of the mine site was <br />initiated. The stacking tube, reclaim tunnel and truck loadout bin were dismantled and <br />removed from the site. The mine portals and mine access road were backfilled and <br />seeded. The two warehouses, shop, substation and ventilation fan were dismantled <br />and removed from the site. <br />On November 17, 1997 the DMG was notified of a slide located immediately <br />west of the reclaimed Bear No. 3 Mine portals. The slide became active on Saturday, <br />November 15~'. Debris from the slide flowed onto the old coal stockpile pad (west of <br />the reclaimed stacking tube) and into the North Fork of the Gunnison River south of the <br />mine access bridge. Shortly after the slide occurred, water started flowing from the east <br />side of the slide scarp. <br />A treatment pond was constructed during May and June 2001 in accordance the <br />plan presented on Drawing 11-4 (rev. 9/23/99). The spring water is piped into the pond, <br />passively treated and then discharged into the North Fork of the Gunnison River. <br />• <br />-1- <br />
