On Map 20C Sheet 2, Pre - Mining and Post - Mining Cross Sections, Section H -H' <br />transects the location of the temporary spoil pile. Please depict the outline of the <br />Temporary Spoil Pile on this cross section. <br />2. On Map 29C Temporary Spoil Pile Design, please incorporate the estimated phased <br />construction of the pile, by year, in the Plan and Section views, and show the Little <br />Collom Sump on Section A-A' and the Plan View. <br />3. On Maps 29B, 41B and 46, disturbance due to construction and operation of the Little <br />Collom Sump is not shown. Please revise these maps to include the Sump area. <br />4.
