This work will not only improve the practical use of these areas, but will help to <br />eliminate poor drainage which may exist in these areas which may contribute to instabilities on the <br />mine site. In addition, the ditch along the south edge of the employee parking lot (D1-2) and the <br />ditch south of the office/bathhouse building (D1-1) will be regraded, if necessary, and lined with <br />asphalt or shotcrete. Both ditches are a gentle grade so that water is slow flowing to pond MB-1 <br />and may also be contributing to instabilities. <br />Greystone Development, Inc. has completed a SedCAD run with lining in these ditches (see <br />attached). This model shows that the lined ditches can be a shallower configuration than the <br />existing unlined ditches, although the minimum configurations, as if unlined, will be constructed. <br />Several other ditches on the mine site will also be lined. After the SedCAD runs are completed <br />and minor revisions approved for the remaining ditches, the appropriate tables in the text and in <br />Exhibit 66 will be revised and provided to the Division. Again, the same minimum configuration <br />as if unlined (shown in the current tables) will be constructed. <br />Please don't hesitate to contact me should you have questions. <br />Sincerely, <br />a j~4TXJL-~/U ~{'V ~ ~vYi"' <br />Kathleen G.
