• • <br />EXHIBIT - C Mining Plan <br />This operation, although dormant at this time, was started as a <br />safety project in 1993. This is reflected in the contours of the <br />mining exhibit. The native topsoil was removed to a depth of <br />approximately 6 inches from the area to be mined and stockpiled at <br />the west edge of the site in a long windrow and then stabilized. <br />As new areas are opened we will continue this process. As per the <br />contours the general thickness of the material to be mined has a <br />maximum depth of approximately 25 feet. <br />This fill dirt extraction operation is expected to have a minimal <br />impact on the surface water system and negligible impact on the <br />ground water system. The extraction site is located on a ridge <br />that is one of the highest points in the area that has a natural <br />runoff to the east and north. All runoff water will be retained <br />inside the extraction site until the complete reclamation and <br />revegetation of the site is complete. To the north several east- <br />west gullies intercept any water that would enter upslope from the <br />site due to snow or rain conditions. Therefore any water entering <br />the site will be collected due to the shape and size of the pit <br />proper. All water will be handled per the storm water runoff map. <br />No NPDES is required for this site. <br />This operation is a pit run extraction site immediately adjacent to <br />a county road, therefore no haul road is necessary. With the <br />exception of the stockpiled topsoil all material to the finished <br />contours will be removed. No water will be used for this site and <br />no ground water will be encountered. No chemicals, fuels or <br />equipment will be stored on site. 1,, <br />b <br />Our intended action for the extraction of the material is as <br />follows: 1) a bulldozer will strip the topsoil to a windrow <br />stockpile on the west edge of the site. 2) frontend loaders will <br />fill trucks with the available material removing the dirt to the <br />finish contours. 3) per the map found in exhibit E the area of <br />extraction will leave slopes of approximately 4 to 1. At the end <br />of the extraction phase the disturbed area will be smoothed and the <br />topsoil redistributed in an even layer across the site. 4) all <br />disturbed areas will be reseeded with a mixture of seeds as <br />recommended by the Double E1 soil conservation service.
