CDPS for the alternative locations will be provided to the OMLR prior to the <br />dewatering of Tract C at those locations, should that be necessary. <br />2. The Applicant has stated two discharge points may be used to dewater Tract <br />C. Please clarify the location of the discharge points and revise the Mining <br />Plan Map as needed. In addition, please describe the dewatering set -up in <br />detail. <br />The locations were shown on the existing maps in the orange triangles, and <br />labeled 009 and DPC, respectively. Point 009 is the existing approved location, <br />and point DPC is an alternative point. An additional alternative point (DPC -3) is <br />shown on the revised extraction plan map, included with this submittal. <br />3. The Applicant has stated groundwater will be discharged into the pond <br />immediately north of Tract C. Please provide the following information: <br />a. Describe the source of water in the pond. <br />b. Describe approximate total volume of the pond. <br />c. Describe the inflow /outflow structures of the pond. <br />d. Provide a brief explanation of how the ponds has historically been used to <br />manage water flows through the area. <br />e. What permits, if any, does the Army Corps of Engineers require for <br />discharging water to the wetlands north of Tract C? <br />f. Will groundwater undergo settling in temporary basins prior to being <br />discharged into the pond? If so, please describe how the temporary <br />basins will be constructed and provide their location on the Mining Plan <br />Map. <br />a. What we suspect is an old SCS Conservation Farm Pond north of Tract C <br />receives tailwaters and irrigation tail waters from the Last Chance Ditch. <br />Irrigation and return irrigation from the former crop lands within Tract C <br />flowed directly into the farm pond, where water levels were managed by a <br />mechanical gate installed in the western end of the pond, releasing waters <br />into an established draw that is presently vegetated with wetland species. <br />b. The pond is estimated to be approximately 0.95± acres in size in its <br />current wetted state with a potential depth of approximately 4.0± feet <br />mean depth and at approximately 1.45± acres of surface exposed water. <br />When full the pond would hold approximately 252,648cu.ft. of water x <br />7.48ga1 /cu.ft. water = 1,889,807.0 gallons of water when full. <br />Varra Companies, Inc. - M- 2009 -006 <br />July 2011 Technical Revision 2 <br />Kurtz Resource Recovery & Land Development Project Correspondence of 3 August 2011 <br />
