Susan Burgmaier 09- Jan-2014 <br />C -1996 -083 TR -85 PAR- GeotechnicaI Page 3 of 3 <br />5. For Volume IX, the Table of Contents should be updated to show the revised page <br />numbering and the addition of a new Buckhorn Geotech analysis. <br />6. At the top of revised page 13 (Volume IX), a paragraph break has been removed for the <br />sentence that begins, "Coal mine waste materials... ". If this deletion was unintentional, <br />please restore the break. <br />7. The first full paragraph on revised page 13 references "Buckhorn Geotech <br />recommendations ". In light of the number of Buckhorn studies that have been <br />incorporated to date, please consider identifying the specific study that established the <br />3h:Iv slopes (we believe it is the study dated 22- Sep -2008 and approved under TR -56). <br />8. A new page 14a has been added to Volume IX, which shows the approximate footprint of <br />the proposed Drying Area. Please add the date of the base photo (25- Sep -2013) to the <br />title block. <br />9. The last paragraph of revised Page 19 (Volume IX) refers to eight working piezometers <br />as being shown on Figure 1. Figure 1 does not appear to have been updated to show the <br />locations of VWP -08, -09, and -10. Also, as discussed in Item lb), above, only five <br />V WPs are currently in working order. Please update this paragraph and Figure 1 to <br />reflect the current status of VWPs at CMWDA42, together with any changes that may be <br />proposed by Buckhorn in response to lb). <br />This concludes my geotechnical adequacy review of the TR -85 application. Please contact me <br />with any questions you may have. <br />Cc: Sandy Brown, DRMS <br />
