2/23/2016 State.co.us Executive Branch Mail - Fwd: MSB slump <br />1313 Sherman Street, Room 215, Denver, CO 80203 <br />leigh.simmons@state.co.us I http://mining.state.co.us/ <br />On Mon, Feb 22, 2016 at 9:28 AM, Welt, Kathy <KWelt@archcoal.com> wrote: <br />FYI - With the heavy snowpack and warm temperatures this past week, there's been a lot of runoff causing <br />the snow and the ground beneath to become very saturated. As a result, the heavy snow shifting downhill on <br />the outslope of the material storage bench (MSB) over the weekend apparently pulled the drain pipe apart <br />causing additional flows to saturate the soils there. A slump resulted, similar to the slump that occurred <br />further to the west a few years ago. The pipe has been repaired and we'll keep an eye on the snow-covered <br />slump. When ground conditions dry, we'll complete repairs of the area. <br />Cathy Weft, <br />Environmental Engineer III <br />Mountain Coal Company, LLC <br />West Elk Mine <br />P.O.
