To facilitate preparation of the reclamation cost estimate, please provide a table that lists all <br />structures, including their dimensions and materials. Also, include any significant regrade <br />volumes for the haul roads. <br />8. Please resolve the apparent discrepancy between Drawing C-15 (which shows sediment pipes next <br />to the refuse pile) and Section 3.2 and the SEDCAD runs (which mention ditches for sediment <br />control next to the refuse pile). <br />9. In Section 4.5 of Exhibit 82, please change the reference to Rule 4.10.1(3) to Rule 4.10.4(3). <br />10.

Please add RPE East to paragraph number 9 on page 2.05-47 of the permit application. <br />14.
