Temporary sediment and drainage control structures including diversion and collection ditches and sediment <br />ponds will be reclaimed at some point in the future, following demonstration that vegetation cover is sufficient <br />to ensure that sedimentation from reclaimed areas does not exceed that from adjacent undisturbed areas. <br />Sections of the Coal Canyon permanent channel diversion near Pond 6, and the Coal Gulch drainage in the <br />vicinity of Pond 11 will be re-aligned and modified in conjunction with removal of the ponds. Also, several <br />permanent ephemeral drainage channels will be constructed across the North Portal facility reclaimed area in <br />association with removal of the temporary upland diversion and Sediment Pond 13. <br />17 <br />
