Exhibit S - Geotechnical Stability <br />(4) At sites where blasting is part of the proposed mining or reclamation plan, the <br />Applicant shall demonstrate through appropriate blasting, vibration, geotechnical, <br />and structural engineering analyses, that off-site areas will not be adversely <br />affected by blasting. <br />To assure the stability of any significant, valuable, and permanent man-made structures <br />that may exist within 200 feet of planned extraction activity, a complete stability <br />analysis was performed by CGRS, Ft. Collins, Colorado, follows. The report is based <br />upon samples collected from the adjacent Durham Operation, located to the immediate <br />east of the Western Sugar permit boundary, and are consistent with materials <br />encountered at both locations. The report verifies that the maximum planned <br />extraction slopes of 1.25H:1V will not pose a hazard to such structures. To the extent <br />practical, operations will remain 125.0± feet or greater from residential structures, not <br />otherwise owned or controlled by the operator. Concurrent grading and reclamation of <br />completed areas of extraction will reduce extracted slopes to a minimum of 2H: IV to <br />3H:1V, or flatter, over a majority of the extraction area, in conformance with Rule <br />3.1.5(7). <br />Varra Companies, Inc.
