Other types of diversions will also be needed at Trapper Mine. For example, <br />• diversions will be constructed on reclaimed areas or undisturbed areas to direct <br />runoff preventing rill or sheet erosion. These structures Witt be constructed in <br />accordance with the generic design criteria outlined in Appendix Q, Section XVII, <br />and discussed in Section 3.6.3.6. <br />• <br />Control of surface runoff along roads is presented in Appendix P. The measures <br />discussed in this section and the culverts which were previously presented are <br />used to manage runoff from the mine areas. <br />Diversion ditches will be inspected annually following spring runoff and upgraded <br />or maintained as needed. <br />4-182 <br />REVISED FEB 13 '87 <br />
