This is not a live stream, it is a gully that could possibly catch <br />water. The affected area recieves at most during the year 11"-15" <br />of percipation. There is no over burden on the gypsum which covers <br />the entire area. Gypsum retains about (16) sixteen times its weight <br />inmoisture. Therefore there is little or no run-off from the affected <br />area. This so call stream ends up in a low area next to State Highway <br />115, which is dry 99;8 of the time. <br />EXHIBIT C MINING FLAN <br />[~f~ 1. The life of the permit (10) ten years. <br />ak <br />;~~Jq~ 2. It. is impossible to seperate the very small amount of topsoil from the <br />~f de-composed ¢ypsum. That is why all the screening and fines will be <br />stock piled as indicated on mining map. Then at the time reclamation <br />begins a percentage of the de-composed gypsum will be mixed with top- <br />~fJ soil (see exhibit D par C). <br />~~~ 3. There is no soil or rock above the gypsum deposit. The gypsum is right <br />on tjte surface. <br />~~~;~ 4. <br />0 <br />~' S <br />~.D~. <br />~~~" <br />The gypsum is in layers, ~perp::~ll~.i+edt~~ a trench-ape mining prrsay. <br />The layer type configuration of the gypsum lends itself to clean mining <br />with out disturbing the entire affected area at one time. <br />The extraction will take place to the permit boundries. <br />The previously disturbed ax•ea consist of dozer marks or. approx. z <br />acre or less, which was done 20+ ,years ago and have since drown over <br />with weeds. <br />
