The proposed locations include: 1) A temporary measure to shift discharge to exisiting <br />approved 1MN Replacement Thickener Underflow Borehole. 2) As a backup plan, a previously <br />approved basin adjacent to Area 1 Pit be re-excavated. 3) As a longer-term solution, installing a <br />thickener underflow borehole and connecting pipeline from the exisiting thickener underflow <br />pipeline. The applicant is proposing additional surface disturbance outside of the area currently <br />approved for disturbance. <br /> <br />The underground coal mining operation is on land located approximately 23 miles Southwest of <br />Steamboat Springs, Colorado. The permit area is further described as follows: <br />
