~~\ <br />David Berry - 4 - April 7, 1998 <br />tYPDES discharge point, and for use in the mine. Include details regarding pump <br />locations, pumping rates and pump drrratior7. Provide as rncrch detail as <br />possrb/e. <br />Bear - A four inch diameter pipe extended from the surface well to the sump so <br />water could be pumped into the mine. A four inch diameter line distributed <br />water from the sump to the mining section. A four inch diameter pipe was <br />installed from the 3rd west seal to the sump. A four inch diameter line was <br />installed from the surface well to the NPDES discharge point at the river. <br />By changing valves located at the surface well and the underground sump, water <br />could be distributed in a number of directions as follows: <br />1. Pump from surface well to underground sump. <br />2. Pump from underground sump to mining sections and dust control sprays. <br />3. Pump from underground sump to NPDES discharge point. <br />4. Gravity flow from 3rd west seal to sump. <br />5. Gravity flow from 3rd west seal to NPDES discharge point. <br />Bear does not believe any water flowed to down gradient locations in the mine <br />beyond any collection point. <br />6.
