__ <br />page c <br />Jim Herron <br />During my completeness review, I have preliminarily identified a number <br />of significant adequacy concerns: <br />Rule 2.05.3(3)(c) ~ 4.03 - Roads (Stability Aspects) <br />The proposed steep cross slope haul and light use road system contains <br />a number of significant cut slopes and fill embankments. These slopes and <br />fills will require appropriate stability analyses. Cross-sectioning should <br />be prepared for the critical cut, fill and composite sections. <br />Rule 2.05.3(6) - Overburden Handling <br />The applicant should provide supporting data for the 15.3 swell factor <br />presented within the application, which the applicant discerned at the nearby <br />Seneca II mine and believes to be representative of the Seneca II-West mine. <br />The applicant should analyze the bulking of the entire range of overburden <br />sections to be encountered, in addition to the average section analyzed within <br />the application as originally submitted. <br />Rule 2.05.3(6)(a) & 4.08 - Blasting <br />The applicant should clearly state whether or not any potentially affected <br />structures exist within 0.5 miles of the permit boundaries. If such structures <br />exist, they should be clearly identified on an appropriate map. <br />Rule 2.05.4(2)(c) & 4.14 - Reclamation Plan - Backfillino & Gradin <br />If the box cut spoil is proven to be acceptable (not necessary to <br />achieve approximate original contour within the mined area), the applicant <br />will have to demonstrate that the proposed placement of the material will <br />be stable, in compliance with Rule 4.14.2(1)(b). In addition, the applicant <br />will have to demonstrate that the critical road cut slopes and fill embankments <br />can be backfilled in conformance with the same stability requirements. <br />Further, the cross-sections presented <br />Topography Map do not appear to agree with <br />overburden bulking. Significant additional <br />support the proposed Postmining Topography. <br />within EXHIBIT 12 and the Postmining <br />the projection of general negative <br />detail will be required to <br />cc: Brian Munson <br />
