Virginia Uranium, Inc. v. Warren
587 U.S. 761
SCOTUS2019Background
- Virginia enacted a long-standing ban on conventional uranium mining on private land after discovery of a large Coles Hill deposit; Virginia Uranium seeks to mine that deposit.
- The Atomic Energy Act (AEA) authorizes the Nuclear Regulatory Commission (NRC) to regulate milling, possession, transfer, enrichment, and disposal of uranium and tailings, but the statute specifies NRC authority applies only "after [uranium's] removal from its place of deposit in nature."
- The AEA contains no express preemption clause addressing state mining laws on private land and includes provisions (§2021) allowing NRC-State agreements to devolve some regulatory authority for radiation safety; §2021(k) states nothing in that section limits state authority to regulate activities for non-radiation purposes.
- Virginia Uranium sued, claiming the AEA (field or conflict preemption) displaces Virginia’s mining ban because the ban was motivated by concern about radiological hazards of milling and tailings and effectively regulates an area reserved to the NRC.
- The district court and Fourth Circuit rejected preemption; the Supreme Court affirmed, holding the AEA does not preempt Virginia’s ban and that §2021(k) does not authorize a broad inquiry into state legislative purpose for activities outside NRC jurisdiction.
Issues
| Issue | Plaintiff's Argument (Virginia Uranium) | Defendant's Argument (Virginia/Commonwealth) | Held |
|---|---|---|---|
| Whether the AEA expressly or impliedly preempts state regulation of conventional uranium mining on private land (field preemption) | AEA and its structure reserve nuclear-safety regulation to the NRC, so state bans of mining for radiation-safety reasons are preempted | AEA expressly limits NRC jurisdiction to post-removal activities; Congress left mining on private land to States | The AEA does not preempt state mining bans; Congress left mining regulation on private land to States |
| Whether §2021(k) authorizes courts to invalidate state laws enacted for radiological purposes even when they govern activities not addressed by the NRC | §2021(k) should be read to displace any state law enacted to protect against radiation hazards, enabling purpose-based preemption of the Virginia ban | §2021(k) clarifies that §2021 does not limit States’ authority to regulate activities for non-radiation purposes and is not a broad preemption clause | §2021(k) is not a broad preemption command; it does not authorize searching inquiries into purpose for activities outside NRC jurisdiction |
| Whether precedent (e.g., Pacific Gas) requires inquiry into legislative purpose and compels preemption here | Pacific Gas’s purpose inquiry implies state laws motivated by radiation-safety concerns are preempted even if they regulate an activity outside NRC’s field | Pacific Gas is confined to activity closely tied to NRC-regulated fields (e.g., plant construction); its inquiry is not a license to probe all state motives for laws outside NRC jurisdiction | Pacific Gas does not compel purpose-based preemption here; courts should not extend motive inquiry to state laws governing activities outside the AEA’s regulatory reach |
| Whether Virginia’s ban creates an obstacle to Congress’s objectives (conflict preemption) | The ban thwarts Congress’s balance between promoting nuclear power and protecting safety and could meaningfully impede development of the nuclear fuel cycle | The AEA contains no text showing Congress intended to displace state control of private-land mining; federal law provides other means (federal land, purchase, eminent domain) if federal action is required | The ban does not present an unavoidable conflict with federal objectives; obstacle preemption not shown |
