Section 11-8-2.3-27-2735 - Disposal of Excess Spoil(a) Each application shall contain descriptions, including appropriate maps and cross-sections, of the proposed disposal site and design of the spoil disposal structures according to §§ 5359-5365. These plans shall describe the geotechnical investigation, design, construction, operation, maintenance and removal, if appropriate, of the site and structures.(b) Each application shall contain the results of a geotechnical investigation of the proposed disposal site, including the following:(1) the character of bedrock and any adverse geologic conditions in the disposal area;(2) a survey identifying all springs, seepage, and ground-water flow observed or anticipated during wet periods in the area of the disposal site;(3) a survey of the potential effects of subsidence of the subsurface strata due to past and future mining operations;(4) a technical description of the rock materials to be utilized in the construction of those disposal structures containing rock chimney cores or underlain by a rock drainage blanket; and(5) a stability analysis including, but not limited to, strength parameters, pore parameters, pore pressures and long-term seepage conditions. These data shall be accompanied by a description of all engineering design assumptions and calculations and the alternatives considered in selecting the specific design specifications and methods.(c) If, under § 5359(d), rock-toe buttresses or key-way cuts are required, the application shall include the following:(1) the number, location and depth of borings or test pits which shall be determined with respect to the size of the spoil disposal structure and subsurface conditions; and(2) engineering specifications utilized to design the rock-toe buttress or key-way cuts which shall be determined in accordance with § 2735(b)(5).11 Miss. Code. R. § 8-2.3-27-2735
