Jason Musick <br />C- 1996 -038 / TR -98 PAR - Geotechnical <br />11- Mar -2015 <br />Page 3 of 3 <br />2. Section E -E' is graphed eastward only to the intercept of coal mine waste with the natural <br />ground. Please extend the cross section eastward to reflect the natural topography for a <br />distance beyond the limits of the gob. <br />3. Section E -E' depicts the East Diversion Ditch as being constructed on top of the Gob surface. <br />This practice does not conform to Rules 4.09.2(7) and 4.10.3(2), which require that all surface <br />drainage from the area above the coal mine waste bank be diverted. Please revise the design <br />for Gob Pile #2 to comply with this requirement. <br />This concludes my preliminary adequacy review of TR -98. Please contact me with any questions you <br />may have. <br />Cc: Dan Hernandez, DRMS <br />
