The Division requests that the operator commit to providing the Division with.a post- <br />mining stream channel survey for each of the three (3) sections to be mined prior io <br />approval of final bond release. Please respond. <br />A post-channel survey for each of the three sections will be provided prior to <br />request for final release of the pit. <br />3. "1'he Division requests that the applicant provide a revised channel dintcnsion cross- <br />sc;e;tion, for each of the three (3) sections to he mined, which shows the dimensions of the <br />beam width nr `:tietback distance" for adjacent lluodplain areas to be excavated to up to <br />15 feet below ground surface. The applicant should also specify the slope dimensions to <br />be maintained during mining of the surrounding, adjacent lands. {The Division <br />recommends adoption of a minimum beret width (ur selhack distance) of lU Icet tram the <br />edge of each stream band and excavation at no steeper than a 1:1 slope). Please respond. <br />Revised channel dimension cross-sections for the three areas arc attached. Actual <br />depth in intermittent drainage depends upon the availability of material. Berm <br />widths will be no less than 10 feet in width, 'I'hc bank on the intermittent drainage <br />side will be no steeper than 1:1. <br />4. The Division requests that the following criteria he followed in re-establishing <br />reclaimed stream bands of Sandy C.rcck: slopes less than ur equal to five (5) feet in height <br />will be rc-established at a 1:1 slope, slopes gyroater than five (5) five feet in height will be <br />ere-established at a 2:1 slope. <br />'1'hc criteria suggested by the Division will be employed as the drainage channel is <br />re-established. <br />5. 'The 1ivision recommends that the applicant/operator leave, where feasible, existing <br />mature coltonwovd trees and/or other large, native woody vegetation. <br />We will attempt to leave large, mature trees whenever possible during excavation. <br />(1.4.12 F.XHBiT G - Recaamation C.'osts <br />G.
