McAtee Construction Company Page 4 <br /> Bank Armoring Plan <br /> more than 300 feet of bank area where armoring needs to be <br /> placed. So a minimum, 710 cubic yards will be stockpiled on the <br /> mine for use in armoring. <br /> The stockpile of armoring material will be placed parallel to the <br /> water flow so it will not interfere with flows in the flood plain <br /> if flooding occurs . It will be within the setback between the <br /> permit boundary and the mine highwall so it is close to the area <br /> where it will be placed. The toe of the armoring will be a <br /> minimum of 3 feet below the average ground water elevation, have <br /> a 3h to lv slope and will be 2 feet or more thick. The armoring <br /> will be installed on 300 foot sections until completed. This will <br /> leave an armored face along the top of the bank and the slope <br /> into the reservoir that is =36 feet wide. <br /> Supplied supporting documents <br /> 2 - Firmett Maps showing the flood plane area and elevations at mine (2016) <br /> Figure G-1 - Bank Protection Plan cross sections <br /> Safety factor calculation page <br /> Revised - July 19, 2022 <br />
