- What it's about
This case asked whether Virginia could ban uranium mining on private land within the state, or whether federal nuclear law left that issue exclusively to the federal government. The Supreme Court held that the Atomic Energy Act did not preempt Virginia’s mining ban.
Question presented
Does the AEA preempt a state law that on its face regulates an activity within its jurisdiction (here uranium mining), but has the purpose and effect of regulating the radiological safety hazards of activities entrusted to the NRC (here, the milling of uranium and the management of the resulting tailings)?
