<br />Memo to Dave Berry <br />Bowie No. 2 Second Additional Geotech Study <br />page 4 <br />clays might vary with moisture. The analyses appear to reflect anticipated site <br />conditions. <br />As I previously observed, two of the road cut situations analyzed by MAXIM <br />using their more conservative (weaker) 2,000 psf soil cohesion value, result it <br />static slope safety factors of 1.4. I find that these proposed operational cut <br />slope configurations are acceptable, based on MAXIM's demonstration that they <br />will remain stable, and will not present an inappropriate risk to the <br />environment or to health and safety. My conclusion, however, assumes <br />that BRL will comply with MAXIM's extensive recommendations for <br />mitigation of potential slope instability. <br />MAXIM concludes the second paragraph of the report by stating; <br />"Recommendations are provided for the mitigation of potential ground water <br />seeps or other instabilities that are either exposed or develop in portal road cut <br />slopes." In the first paragraph on page four of the report, MAXIM states; "...the <br />strength values used in these analyses are generally at the low end of the range <br />of values determined by the laboratory testing and would indicate that the <br />results are conservative. However, these results assume relatively dry <br />conditions and some precautions will be necessary if ground water is <br />encountered in cuts." The section of the report titled "Construction <br />Recommendations" commences with the statement; "The recommendations <br />presented in our previous studies regarding the construction of cut slopes <br />should be followed." <br />J. E. Stover & Associates has submitted a new Volume VII to the Bowie No. 2 <br />permit application. Volume VII contains the various Geotechnical Studies <br />prepared and submitted to date in response to our original and supplemental <br />adequacy comments. Section 1 of Volume VII contains an Introduction, prepared <br />by J. E. Stover and Associates. This introduction briefly summarizes the <br />various geotechnical studies, including a rendition of the geotechnical design, <br />construction control, mitigation techniques, and monitoring recommendations <br />presented within each of the reports. However, J. E. Stover and Associates' <br />summary statement appears to selectively commit BRL to implementing only a <br />
