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.
