The two pipes will pass through the EPDM liner with a bentonite seal and after the seal, there will <br />be no perforations in the pipe. These pipes will deliver the mine water to the mine water pond, which is <br />located within 200 feet to the west of the leach field, as shown on Map G -10. <br />The Geotextile product data sheet is shown below: <br />3 <br />
