-z- <br />MCR has repaired the gully on the face of the crusher <br />fines stockpile by filling it with similar material. The <br />crusher fines stockpiles have a high degree of natural <br />cohesion, and so long as running water is directed away <br />from them they are stable, Thus MCR does not propose any <br />further stabilization, other than positive drainage of <br />water away from the stockpiles and seeding the outslope <br />as noted below. <br />The crusher fines stockpile consists of limestone mixed <br />with small amounts of clay, and is of identical <br />composition to the bedrock, alluvium and colluvium found <br />in the area. These same materials are the progenitors of <br />the minimal soils in the area as well. Limestone <br />outcrops and limestone debris form the "streambeds'~ in <br />the permit and immediately adjacent areas fall of which <br />are high-gradient ephemeral drainages). Therefore MCR <br />feels that the fines materials deposited in the drainage <br />below the stockpile have not impacted the hydrologic <br />balance or the quality of surface water, and there <br />appears to be no need to remove these materials from the <br />drainage. Since the fines are essentially natural <br />materials, the i~se of tracked equipment that would be <br />required t.o remove them from the drainage would cause <br />considerable unnecessary surface disturbance. Final)>•, <br />at the southwest edge of the mineral lease (see Map C-1, <br />Mining Plan, in M-82-121), this drainage intersects a <br />public road (Transfer Trail Road, White River National <br />Forest Road 602 and a Glenwood Springs city road), and <br />for a distance of approximate O.i5 miles, to the <br />intersection of the Transfer Trail Road and Traver Trail <br />(paved access road to the Oasis Creek subdivision) this <br />road is in the "streambed" of the subject drainage. This <br />road, which is the primary Glenwood Springs area access <br />road to the Flat Tops and a very popular hunting and <br />4WD/ATV touring road, and which predates the limestone <br />quarrying operations, is surfaced with the same material <br />as that washed out from the crusher fines stockpile, and <br />has been since at least 1974. Thus further transport of <br />the washout material from the quarry downstream, should <br />it occur, would have no noticeable affect. <br />MCR does propose to place hay-bale check-dams across the <br />drainage to its intersection with the Transfer Trail Road <br />at approximately 200-ft intervals, to slow potential <br />
