Sealing and Managing Drill Holes <br />All former CEC drill holes completed as part of the 1978 test drilling exploration <br />program, and located within the Permit Area have been changed to ground water <br />monitoring sites, have been mined through, or have been permanently plugged. <br />All ground water monitoring wells currently used in the CEC site ground water <br />monitoring program, at site closure, will be sealed by placing a cement grout plug from <br />the bottom of each well to within 10 feet of the final ground surface. <br />• <br /> <br />t t ac to/oo <br />
