17. The Exhibit F Reclamation Plan Map depicts the proposed post -mining topography within the permit <br />boundary. The Division believes the northwest and southeast portions of the depicted post -mining topography <br />do not connect to existing topography properly. Please update this map to show the current topography that <br />will remain unchanged which lies outside of the permit boundary and adjust any post -mining topography, as <br />necessary. <br />See the revised topography map attached. <br />18. On the Exhibit F Reclamation Plan Map, the Operator states that "Slope to be furrowed approx. every 50' to <br />toe for erosion control"; please further explain this within the Exhibit E Reclamation Plan. <br />See the attached sheet with revised language for reclamation. <br />19. The Operator states the gravel operation will be dry, not intercepting groundwater. Please note the mining <br />operation must stay a minimum of two (2) feet above the groundwater elevation to be considered a "dry" <br />operation. <br />We recognize that mining must stay a minimum of two (2) feet above groundwater elevation. <br />20. In accordance with Rule 6.4.10(1)(a), please provide quantitative estimates of cover and height for the <br />vegetation described in Exhibit J of the application. <br />Vegetative ground cover on areas that are undisturbed is estimated to be 6040%. Heights range from <br />2" up to a foot high, depending on species. <br />21. As proposed, the Operator requests to have the site's reclamation cost estimate only to be calculated for Tract <br />1, the original 110c permit boundary. Please note that the Division observed approximately 5.89 acres had <br />been disturbed outside of this boundary during the October 6, 2014 inspection. All current disturbances will <br />need to be bonded for. Please propose to be approved for all the tracts currently affected, or revise the current <br />shapetsize of Tract 1 to encompass (at a minimum) the current disturbance; if the later is chosen, the Mining <br />Plan, Mine Plan Map, and Reclamation costs will need to updated and resubmitted. <br />The size and shape of Tract 1 has been revised to encompass the originally identified disturbance <br />outside the original boundaries. See attached revisions to the Mining Plan and Mine Plan Map. The <br />originally submitted cost estimate for the application covered the entire 32 acres.
