40 CFR Part 192
The U.S. Environmental Protection Agency (EPA) is proposing new health and environmental protection standards under the Uranium Mill Tailings Radiation Control Act (UMTRCA) of 1978. The standards proposed in this action would be applicable to byproduct materials produced by uranium in-situ recovery (ISR) and would be implemented by the U.S. Nuclear Regulatory Commission (NRC) and NRC Agreement States. The EPA initially proposed new health and environmental protection standards for ISR facilities on January 26, 2015; however, the EPA has decided to re-propose the rule and seek additional public to comment on changes to the original proposal, including changes in the regulatory framework and approach, based on public comment and new information received from stakeholders. The first standards for uranium recovery were issued by the EPA in 1983 when conventional mining and milling were the predominant methods of uranium extraction, and were last amended in 1995. Since the early 1990s, ISR has mostly replaced conventional milling. This proposed rule would strengthen the existing regulations for uranium recovery by adopting new standards addressing groundwater hazards specific to ISR facilities. As with the original proposal, the primary focus of this proposal is groundwater protection, restoration and long-term stability. The most significant changes from the original proposal include: Removing the default 30-year long-term monitoring provision and shifting to a Resource Conservation and Recovery Act (RCRA) Subtitle C corrective action framework as a model rather than a RCRA Subtitle C landfill framework; adding specific criteria and procedures for approving termination of long-term stability monitoring; deleting gross alpha particle activity from proposed Table 1 to subpart F of 40 CFR part 192, and allowing more flexibility for the NRC or Agreement States to determine on a site-specific basis the constituents for which concentration based standards are set. The EPA has also sought to clarify how these standards under UMTRCA complement, and do not overlap with, the requirements of the Safe Drinking Water Act (SDWA). This action also proposes amendments to certain provisions of the existing rule to address a ruling of the Tenth Circuit Court of Appeals, to update a cross-reference to another environmental standard and to correct certain technical and typographical errors. The proposed rule has been informed by input from the NRC, the U.S. Department of Energy (DOE), states, tribes, industry, environmental groups and other stakeholders, and would promote public health and protect groundwater by reducing the potential for groundwater contamination after production has ceased, and in aquifers adjacent to ISR facilities during uranium recovery.
