DOE restricts access to the radiological control area of the site where the mill tailings and the highest concentrations of soil contamination exist. This area is fenced and signs are posted in accordance with the requirements of Title 10 Code of Federal Regulations Part 835 and relevant DOE guidelines. Staff are on site 7 days per week and perform security, maintenance activities, erosion control measures, storm water prevention activities, and health and safety oversight of the field activities.

A vinyl-covered maintenance facility and the metal structure where lids will be applied and removed from the tailings containers were installed in the northwest portion of the Moab site beginning in July. Two bridge cranes are planned to be installed inside the lidding structure in January 2009.

A portion of Moab Wash was realigned away from the tailings pile and widened to increase the flow capacity. The Moab Wash realignment, which was completed in December 2008, is designed to reduce the risk of tailings entering the wash as it moves toward the Colorado River during high intensity storm events. As the existing wash was realigned, contaminated areas under it were remediated.
