MID-CONTINENT RESOURCES <br /> P.O.Box 1298 <br /> Glenwood Springs, CO 81602 <br /> August 19, 1993 <br /> Michael Claffey <br /> U.S. Army Corps of Engineers <br /> 402 Rood Ave. <br /> Room 142 <br /> Grand Junction, CO 81501 <br /> Dear Mr. Claffey: <br /> Mid-Continent Resources, as part of reclamation work which is on-going at our mine <br /> site, would like to perform work, as described below, which I believe is allowed under <br /> Nationwide Permit#26, so that no further permitting is required. I would appreciate a <br /> confirmation as to whether this is correct. <br /> As we discussed at your site visit on August 11, in connection with reclamation at our <br /> Mine #5, we would like to route a small section of Coal Creek back to its former <br /> channel. At some time in recent years the stream changed course and is now flowing <br /> into the toe of an embankment which forms the outer-most edge of a yard area which <br /> had been used in connection with the mine operations. The stream is eating into the <br /> toe of the embankment, which could over time undermine its stability. Further, we <br /> cannot place topsoil on this embankment at present for fear of accidentally dropping <br /> the soil into the creek. <br /> The stream had been blocked from its former channel by rock debris, which we propose <br /> to use to plug the current channel, thus re-directing the stream. We estimate the <br /> amount of rock material to be about 10 cu. yds. <br /> When the stream has been re-directed to its former channel (i.e. away from the toe of <br /> the embankment) additional rock will be placed at the base of the embankment. We <br /> will obtain this rock material from sources outside the normal high water of the stream. <br /> I'also anticipate placement of rock material to fill in the channel from which the stream <br /> has been re-directed to ensure it does not in future return to the toe of the <br /> embankment. <br /> There is a small flow of water (estimated at less than 10 gpm) which comes from a <br /> spring above the yard area which presently flows into the channel from which we are <br /> seeking to re-direct the stream. It appears that this flow previously entered Coal Creek <br />
