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.

DOE recently completed remediation of an additional 29 acres of non-pile contaminated soils on the northwest portion of the Moab site in preparation for constructing materials handling infrastructure necessary to relocate the uranium mill tailings to the Crescent Junction, Utah, disposal site.

Above-normal snowfall in the Rocky Mountains during the 2007 to 2008 winter resulted in abnormally high runoff and, therefore, flow rate in the Colorado River. Because the Moab site is bounded on the east by about 3,500 feet of riverbank and the site is transected by Moab Wash, protection of the site from flood damage is essential. DOE took preventive measures against flooding of the Moab site; however, the river did not rise to a level that caused any flooding during the 2008 runoff.
