6.3.4 EXHIBIT D -Reclamation Plan <br /> (1) Describe Reclamation Plan <br /> (a) Replace Overburden <br /> The Quarry has overburden/subsoil depth estimated to be 0 inches deep. Limestone from <br /> the Brown quarry will be mined using a series of cuts measuring approximately 15 feet <br /> wide and 400 feet long cuts. Waste limestone will remain in the pits.No overburden will <br /> be replaced. <br /> Limestone swells about 1.6 times from bank to loose. It is estimated the swelled waste <br /> sandstone will equal the volume of the dimensional limestone removed from the quarry. <br /> Therefore,the final contours will nearly equal the original contours. <br /> The culvert in the channel below the quarry will be removed and the drainage channel will <br /> be restored to its predisturbance configuration. The pit access road will be regraded to <br /> original adjacent contours. <br /> The rock check dam will be graded to create a smooth channel. <br /> The Yard will be graded to approximate original contour. Temporary structures will be <br /> removed. Fencing will remain in place until reclamation success is achieved. <br /> (b) Maximum Gradient of Reclaimed Slopes <br /> The maximum gradient of the reclaimed slope at the Quarry is 2H:1V. The natural existing <br /> slope of the Quarry is also 2H:1V. The reclaimed slopes at the yard and road will be flatter <br /> than 1H:5V. <br /> The post mining land use of the reclaimed quarry, road and yard will be for recreation and <br /> wildlife habitat. Recreational use of the area consists primarily of sightseeing, hiking, <br /> mountain biking,off road vehicle use, camping and hunting. Most of the area is <br /> characterized by steep and extremely rugged cliffs which are not conductive to recreational <br /> uses. There is no fishing in the general area. <br /> (c) Site Re-vegetation <br /> (i) Approximately 6 inches of topsoil will be salvaged and stockpiled from the <br /> Quarry, new road and the Yard. The topsoil salvaged should be of adequate <br /> quality to be a good plant growth medium. The rock check dam is <br /> constructed in a channel that is mostly covered with volcanic cinders so <br /> there is no topsoil or vegetation present in this area. <br /> (ii) Site preparation will include regrading to approximate original contour, <br /> spreading topsoil to an adequate depth. Re-vegetation will be performed in <br />
