The Natural Resources Defense Council and other plaintiffs sued the Nuclear Regulatory Commission (NRC) and the New Mexico Environmental Improvement Agency (NMEIA). They sought declaratory and injunctive relief preventing the agencies from issuing uranium-mill operating licenses in New Mexico without first preparing environmental impact statements under the National Environmental Policy Act (NEPA).
New Mexico operated under an agreement authorized by § 274(b) of the Atomic Energy Act, through which the NRC allowed NMEIA to license certain nuclear activities. The plaintiffs alleged that the delegation to the state could not eliminate NEPA's environmental-impact-statement requirement and, alternatively, that a licensing program without such statements conflicted with the Atomic Energy Act.
On the day the complaint was filed, NMEIA issued United Nuclear Corporation a license to operate a uranium mill. United Nuclear's unopposed motion to intervene was granted. Kerr-McGee Nuclear Corporation, which operated a New Mexico uranium mill and had a renewal application pending, and the American Mining Congress, representing industry members, also moved to intervene. The district court denied both intervention as of right and permissive intervention, concluding that United Nuclear adequately represented their interests and that additional parties would make the case unwieldy. It permitted them to submit amicus briefs instead. Kerr-McGee and the American Mining Congress appealed.
Issue #1
Whether Kerr-McGee and the American Mining Congress claimed a sufficiently protectable interest in the litigation to support intervention as of right under Rule 24(a)(2).
Holding
Yes. Their interests in present and future uranium-mill licenses were sufficiently direct and substantial.
Reasoning
Rule 24(a)(2) does not demand that an applicant have a strictly direct interest in the precise license immediately challenged. The relevant inquiry connects the claimed interest with the practical consequences that the litigation may have for the applicant's ability to protect it. Supreme Court authority likewise permits intervention where an interest, though not identical to the property or transaction formally at issue, will be impaired by the outcome.
The requested relief could require environmental impact statements before New Mexico issues any uranium-mill license or could suspend or terminate the NRC-New Mexico agreement. Kerr-McGee, a major holder of uranium properties in New Mexico with a mill operating under a state license and a renewal pending, therefore faced substantial practical consequences. The American Mining Congress's members faced comparable consequences for their licensing interests.
These concrete business and licensing interests differed sharply from the generalized public interest found inadequate in Allard v. Frizzell. A procedural change requiring environmental review before state licensing would create significant complications for Kerr-McGee and the mining industry, even if the court did not assume that federal rather than state licensing would produce substantively better treatment.
Issue #2
Whether disposition of the action could, as a practical matter, impair or impede the applicants' ability to protect their interests.
Holding
Yes. A ruling for the plaintiffs could practically impair the applicants' future licensing interests, even if it would not formally bind them under res judicata.
Reasoning
Rule 24(a)(2) expressly asks whether impairment may occur 'as a practical matter,' so the inquiry is not confined to whether a judgment would have formal res judicata effect against an absent applicant. Significant practical legal effects, including the force of precedent, may satisfy the rule.
Because this was a case of first impression and the environmental-review question would recur in substantially similar form whenever New Mexico licensed a uranium mill, an adverse ruling would carry substantial stare decisis weight. The theoretical possibility of relitigating the issue in later cases did not meaningfully protect the applicants, since a contrary result in materially identical future litigation would be unlikely.
The presence of the NRC and NMEIA as defendants could make the ruling even more consequential than ordinary precedent. If they were ordered to alter their licensing practices or their agreement, applicants seeking future licenses would directly experience the resulting change.
Issue #3
Whether United Nuclear adequately represented the interests of Kerr-McGee and the American Mining Congress, defeating intervention as of right.
Holding
No. The applicants met their minimal burden of showing that United Nuclear's representation may be inadequate.
Reasoning
Under Trbovich v. United Mine Workers and the Tenth Circuit's decision in National Farm Lines v. ICC, the applicant bears only a minimal burden: it need show only that existing representation may be inadequate. When interests are similar but not identical, intervention ordinarily should be allowed unless it is clear that the existing party will adequately represent the absent party.
United Nuclear's position differed materially from the applicants' positions because it had already received the particular license challenged in the complaint. It might have litigation interests different from companies seeking renewals or future licenses; for example, it possessed a laches defense unavailable to Kerr-McGee and the other industry interests. Although the court viewed a compromise favoring United Nuclear's already-issued license as a remote possibility, the possibility of divergent interests was enough under the minimal-burden standard.
The American Mining Congress represented numerous companies with varied licensing interests, and Kerr-McGee could add its own perspective to the defense. Their participation also had value because they would be bound by the result. The district court's concern about delay and unwieldiness did not justify denying intervention to these two applicants, particularly because the court could manage the proceedings and the Mining Congress's presence reduced any need to add more industry parties.
