EPA's regulations in 40 CFR part 192 establishes standards for the protection of public health, safety, and the environment from radiological and nonradiological hazards associated with uranium ore processing and disposal of resulting waste materials. These cross-media standards, which apply to pollutant emissions and site restoration, must be adopted by the Nuclear Regulatory Commission, their Agreement States, and the Department of Energy. We propose to review the standards in the existing rule and to revise the regulations, taking into particular account the significant changes in uranium industry extraction technologies and their potential impacts to groundwater. In addition, new facilities being proposed in states from Virginia to Alaska add to the importance of this effort.
