Page 11 <br /> 6.4.19 EXHIBITS - Permanent Man-made Structures <br /> Where the affected lands are within two hundred (200) feet of any significant, valuable and <br /> permanent man-made structure, the applicant shall: <br /> (a) provide a notarized agreement between the applicant and the person(s) <br /> having an interest in the structure, that the applicant is to provide compensation <br /> for any damage to the structure; or <br /> (b) where such an agreement cannot be reached, the applicant shall provide <br /> an appropriate engineering evaluation that demonstrates that such structure shall <br /> not be damaged by activities occurring at the mining operation; or <br /> (c) where such structure is a utility, the Applicant may supply a notarized <br /> letter, on utility letterhead, from the owner(s) of the utility that the mining and <br /> reclamation activities, as proposed, will have "no negative effect" on their utility. <br /> 6.5 GEOTECHNICAL STABILITY EXHIBIT <br /> (1) On a site-specific basis, an Applicant shall be required to provide a geotechnical <br /> evaluation of all geologic hazards that have the potential to affect any proposed <br /> impoundment, slope, embankment, highwall, or waste pile within the affected area. <br /> A geologic hazard is one of several types of adverse geologic conditions capable of <br /> causing damage or loss of property and life. The Applicant may also be required to <br /> provide a geotechnical evaluation of all geologic hazards, within or in the vicinity of <br /> the affected lands, which may be de-stabilized or exacerbated by mining or <br /> reclamation activities. <br /> (2) On a site-specific basis, an Applicant shall be required to provide engineering <br /> stability analyses for proposed final reclaimed slopes, highwalls, waste piles and <br /> embankments. An Applicant may also be required to provide engineering stability <br /> analyses for certain slopes configuration as they will occur during operations, <br /> including, but not limited to embankments. Information for slope stability analyses <br /> may include, but would not be limited to, slope angles and configurations, <br /> compaction and density, physical characteristics of earthen materials, pore pressure <br /> information, slope height, post-placement use of site, and information on structures <br /> or facilities that could be adversely affected by slope failure. <br /> (3) Where there is the potential for off-site impacts due to failure of any geologic <br /> structure or constructed earthen facility, which may be caused by mining or <br /> reclamation activities, the Applicant shall demonstrate through appropriate <br /> geotechnical and stability analyses that off-site areas will be protected with <br /> appropriate factors of safety incorporated into the <br /> VARRA COMPANIES, INC.
