State authority to regulate radiation below level of regulatory concern of Nuclear Regulatory Commission

No provision of this chapter, or of the Low-Level Radioactive Waste Policy Act [42 U.S.C. 2021b et seq.], may be construed to prohibit or otherwise restrict the authority of any State to regulate, on the basis of radiological hazard, the disposal or off-site incineration of low-level radioactive waste, if the Nuclear Regulatory Commission, after October 24, 1992, exempts such waste from regulation. This section may not be construed to imply preemption of existing State authority. Except as expressly provided in subsection (a), this section may not be construed to confer on any State any additional authority to regulate activities licensed by the Nuclear Regulatory Commission. The term “low-level radioactive waste” means radioactive material classified by the Nuclear Regulatory Commission as low-level radioactive waste on October 24, 1992. The term “off-site incineration” means any incineration of radioactive materials at a facility that is located off the site where such materials were generated. The term “State” means each of the several States, the District of Columbia, and any commonwealth, territory, or possession of the United States.
