Created digital version of Figure 3.1-7 with the 2007 as-built reclaimed <br />contours. <br />2. Figure 3.1-7A will be deleted from the permit. <br />3. Created digital version of Figure 3.1-6 with the 2007 as-built reclaimed <br />contours. <br />4. Figure 3.1-6A will be deleted from the permit. <br />5. Created digital version of Figure 3.1-5 with the 2007 as-built reclaimed <br />contours. <br />6. Created a new Figure 3.1-8A which shows cross sections with the as- <br />built, reclaimed contours for the reclaimed ground surface and used the <br />'original ground' topography surveyed in 2002. <br />7. Created a Figure 3.1-9A which shows cross }sections with the as-built, <br />reclaimed contours for the reclaimed ground surface and used the 'original <br />ground' topography surveyed in 2002. <br />8. Updated Table 3.9-3 to reflect the minimum 3' bottom width of portal <br />channel H. Channel H was also constructed with 15" riprap, per SedCad <br />riprap sizing requirement. The riprap sizing was updated on Table 3.9-3 <br />and the Master List ditch Summary table. Table 3.9-3 was also updated <br />with the as-built ditch design parameters for the rest of the portal area <br />ditches (A-H).
