Ground control review underway at WIPP following rock fall

The DOE says a ground control review has started at WIPP following a rock fall.

Crews found salt rock debris last week during routine monitoring and inspections of the Panel 4 entrance underground.

Panel 4 closed six years ago. It has seven rooms filled with waste.

The area went under restricted access this March. However, engineers two weeks ago found a bulge in a temporary closure that more strictly prohibited access.

Work continues to determine other areas underground that may need to close because of ground control concerns.
