<br />The Unnamed Alluvium soil is deep, nearly level and poorly <br />to moderately well drained. The soil is found on level bottom- <br />lands adjacent to the stream channel of the North Fork of Bolton <br />Draw in a depositional area below upland drainages. Runoff is <br />slow. <br />The Tiagos series are deep, nearly level to moderately slop- <br />ing soils found on upland drainageways. They are wll drained <br />soils. <br />The Morset series are deep, nearly level to level soils <br />found on old high terraces. They are well drained soils with <br />medium runoff. <br />The Fleutsch series are deep, nearly level to moderately <br />sloping soils found on old alluvial fans. The soil is wll <br />drained and runoff is medium. <br />Wyoming Fuels proposes to remove vegetation and then strip <br />topsoil for either stockpiling or immediate re-use as conditions <br />allow (pages 43 and 44, Vol. 1 of the permit application). Top- <br />soil will be segregated from overburden and spoils. The appli- <br />cant proposes to remove and replace topsoil in the summer and <br />fall months. Topsoil should be moved and worked only when the <br />physical and chemical properties of the soil can be protected. <br />Therefore, the following stipulation is proposed: <br />Topsoil will be moved and worked only when soil moisture is <br />well below field capacity. <br />The applicant has not provided an adequate schedule showing the <br />asmount and area of topsoil to be stripped ahead of, and replaced <br />behind, mining. Table II of Addendum II can be used to make <br />rough approximation, but it is not sufficient to check yearly <br />topsoil availability and movement. Ideally, the size of the area <br />from which topsoil is removed at any time should be limited, so <br />in order to evaluate this, the following stipulation is proposed: <br />-91- <br />
