C-2008-086 <br />PAR - MLT <br />27-Jan-2009 <br />Page 4 of 5 <br />17. Page 2.05-53 of the text (1St paragraph) states that, "As each 50 foot lift is <br />complete it will be plated with 44.3 inches of subsoil..." This description seems <br />to be at odds with coal mine waste construction details contained elsewhere in the <br />permit. Please review the text here, and revise or explain in greater detail. <br />Volume II - Mans <br />Map 15 Series <br />18. Legend <br />a. Symbol for Light Use Road does not match map <br />b. Please add the symbol for Access Road <br />c. Please add the symbol for Conveyor <br />19. Map 15-6 - Contour line on top of pile incorrectly labeled 5600; should be 5580. <br />Map 19 Series <br />20. Map 19-1 Section C-C appears to be facing northward, rather than southward as <br />indicated by the arrows in plan view. Please reverse the section, or change the <br />orientation of the arrows. <br />21. Map 19-2 Section H-H does not give cut slope H:V for the rail spur. Please add <br />this slope (if Section H-H is perpendicular to the rail spur). <br />Map 21 Series <br />22. In Maps 21-A, 21-C, 21-E, 21-F and 21-H Plan View - arrows for cross sections <br />point the wrong direction. Please reverse the section, or change the orientation <br />of the arrows. <br />Volume III - Exhibits <br />Exhibit 8 - Engineering Geological Evaluation (Vector Enzineering - 13-Nov-2006) <br />23. Recommendation No. 1) states, "Site-specific engineering designs and rockfall <br />mitigation measures will be necessary to ensure the safety of both infrastructure <br />and personnel in mapped rockfall areas. Slope stability studies and, where <br />appropriate, rockfall stability analyses should be completed for structures <br />proposed in the rockfall hazard area." No rockfall stability analyses and <br />mitigation measures have yet been incorporated into the Permit Application <br />Package. Please address these items, or provide a justification as to why they <br />should not be required.
