sufficiently smooth following land leveling. For flood irrigated areas, furrows 4 to 6 <br />inches deep will be created on 30 -inch centers. Fertilizer will be applied by tractor <br />using a broadcast spreader at the rate specified by the laboratory analysis. Fertilizer <br />will be applied in the Spring of the same year that the initial fertility testing is done. <br />Ongoing fertility testing after initial seeding is described in Section 2.05.4(2)(e), <br />subsection 4.6. <br />For non -prime farmland areas that will be reclaimed to Dryland Pasture post- mining <br />land use, where the topography is suitable for irrigation to be applied in the future, the <br />following preparations will be applied: Graded Bench 1 surface spoil will be ripped to <br />a depth of 2 feet to reduce compaction. Ripping will be accomplished by a bulldozer <br />fitted with ripping teeth, or other suitable equipment. The single lift of topsoil will be <br />ripped or deep disked to the full depth of the lift, following replacement. The surface <br />of the topsoil will be land leveled and rock - picked. Soil fertility testing will be <br />conducted within three months following topsoil placement. Samples will be analyzed <br />by a laboratory, which will provide fertilizer recommendations to promote growth of <br />the grass / forb seed mix. Prior to final seedbed preparation, soil conditioning and <br />weed control tillage will be carried out through disking. Harrowing will be conducted <br />prior to seeding if the surface is not sufficiently smooth following land leveling. <br />Fertilizer will be applied prior to seeding. Phosphorus fertilizer will be applied in the <br />Spring of the same year that the initial fertility testing is done, and will be tilled into <br />the soil prior to seeding. Nitrogen fertilizer swill be surface applied one time, if <br />warranted based on initial testing, in the fall following the first full growing season. <br />For Dryland Pasture areas reclaimed to slopes steeper than 15 %, the single lift topsoil <br />will be ripped full -depth using a motor grader with rippers. The grader will operate <br />along the contour, creating roughened surfaces to trap moisture and prevent erosion of <br />the soil. <br />V. Sealing of Drilled Holes and Underground Openings <br />The Division will require that each hole, well or other underground opening be capped, <br />sealed, backfilled, or otherwise properly managed (4.07.3). <br />VI. Use of Explosives <br />A. The applicant has proposed to conduct blasting less than 1,000 feet from a school, <br />church, hospital, or nursing facility, or less than 500 feet from disposal wells, <br />petroleum or gas storage facilities, municipal water - storage facilities, <br />fluid - transmission pipelines, gas or oil collection lines, or water or sewage lines. The <br />Division proposes to approve these lesser distances based upon pre - blasting surveys, <br />seismic investigations, and other appropriate investigations (4.08.4(7)). <br />B. The Division is proposing to approve the use of seismograph recorders to aide in the <br />design of blasts to determine maximum weight of explosives per delay. The design is <br />based upon cumulative seismograph records of each blast. The designs ensure that <br />47 <br />
