<br />Additionally, there appear to be some discrepancies regarding channel lining <br />requirements for the upper road reclaimed Channels "C" through "H". On page <br />3-8 of Section 3.3.2 there is reference to lining channel segments that are not <br />formed in rock outcrop with riprap. Page 3-15 of Section 3.3.4 describes <br />installation of riprap keys at channel inlets and outlets, but does not specify riprap <br />lining along the length of the channels. Table 3.9-3 desigis specify that all <br />channels will be lined with "LANDLOCK 450" or equivalent. Map Figure 3.1-7 <br />indicates a riprap lining 0.5 feet thick for Channel "G", and a riprap lining 1.0 feet <br />thick for Channel "H". This detail is lacking on the map figures that depict cross- <br />sections for Channels "C" through "F". <br />Please review these materials and revise as appropriate to clarify the <br />applicable design specifications and ensure consistency among text, tables, <br />and figures. <br />9. Please take note of the commitment on page 3-12 to stake the highwall crest <br />reduction disturbance boundary, and to contact BLM prior to initiation of <br />earthwork to allow for inspection and verbal approval from BLM. Please <br />contact DRMS at the same time, so that we may arrange for a joint <br />inspection. <br />
