6.4.4 Exhibit D - Mining Plan <br />6. Maximum excavation depth and average slope for pit wall information has <br />been added to the revised Exhibit D under Mining Methods. <br />7. Stockpile stabilization will be preformed by revegetation (hydroseeding). <br />Revegetation specifications have been added to the Earthmoving section <br />of Exhibit D. <br />8. Fuel will be stored onsite in the processing and batch plant areas.. <br />Weiland Inc. has prepared a SPCC Plan per EPA specifications, and,the <br />plan will be kept onsite. A letter from CEC is being sent (unser a separate <br />mailing) to the Division affirmatively stating that the plan. has been <br />implemented. <br />9. Proposed overburden stockpile locations are shown on Exhibit C-2 and <br />overburden stockpiles are described in Exhibit D. Stockpiles will not be <br />placed around the entire permit boundary. It should be noted that <br />overburden stockpiles will only be necessary for initial excavations of <br />mining Phases (and Phase II cell 3) whereas subsequent overburden <br />excavation materials will be directly backfilled. <br />10. Floodwater will be pumped back to the river, should it enter the pit. <br />11. Exhibit C-1 has been updated'to include groundwater observation well <br />information. <br />12. Shale stockpile will not be present in significant quantities. Shale will, be <br />.placed directly onto pit slopes. <br />6.4.5 Exhibit E - Reclamation Plan <br />13. The average depth of'shale is 17-18ft below ground surface and the <br />maximum depth is 25=26ft below ground surface. <br />14. There will be no berm constructed around the perimeter of the pit. <br />15: The visual berm or screening berm along the northeast corner of the pit <br />will be removed as shown in Exhibit F. <br />16. Exhibit F has been updated to include topsoil on the top 6 ft of the clay <br />liner except for the eastern shoreline where gravel slope protection. is <br />specified. <br />17. Exhibit E has been updated to include slope protection based on wave <br />action analysis (see Exhibit E Attachment A). Prevailing winds are west to <br />east, therefore slope protection is only specified along the. eastern <br />shoreline. <br />18. The final storage volume is the main reservoir is 470 acre-ft. The final <br />storage volume for the smaller reservoir is 6 acre-ft.
