Susan Burgmaier -5- September 16, 2013 consistent for all of the sections. Please revise the label for the green line to read, "Permitted Top of Pile (TR -76)" so that it is clear no changes are being proposed to this section with TR- 81. BOW2: The green line was revised to show the permitted TR -76 configuration. See Figure 1. Where necessary, colors of lines in other sections were revised for consistency. 20. DRMS: On Volume IX Figure 1 Section F -P; please revise the label for the purple line to read, "Permitted Cut Slope (TR -76)" so that it is clear this slope is not being revised with TR- 81. BOW2: The cut slope will change with this revision. TR -76 approved a 2H:1V cut slope based on the topography we had when that revision was submitted and approved (aerial topography from 2012). Part of this revision incorporates an on- the - ground survey and the contours, both design and existing ground were updated to reflect the minor changes based on the differences between the two surveys. The geotechnical analysis incorporates the 1.5H:1V cut slope in the analysis performed on July 29, 2013. 21. DRMS: In the Legend for Volume IX Figure 1, there is a solid black circle symbol referring to Lambert sample locations. The circle does not appear on the map, and is no longer needed. Please delete the sample location symbol from the legend. Please add a symbol for the piezometers. BOW2: The legend has been updated on Figure 1. 22. Page 2.05 -32 has been revised to incorporate a change in haul road width for the haul road to gob pile #3. Please feel free to contact me if you have any questions. Sincerely, Tamme Bishop, P.E.
