Opinion for the Court filed by Circuit Judge GARLAND.
Petitioners challenge a decision by the Nuclear Regulatory Commission to grant a license permitting the construction and operation of a spent nuclear fuel storage facility in Utah, on land belonging to the Skull Valley Band of Goshute Indians. After the Commission approved the license, the Interior Department’s Bureau of Land Management and Bureau of Indian Affairs denied applications for rights-of-way and a lease, respectively. Because it is speculative whether the project will ever be able to proceed, we find the petitioners’ challenge unripe and direct that the case be held in abeyance. 1
I
In 1997, Private Fuel Storage, L.L.C. (PFS), a consortium of eight nuclear utilities, applied to the Nuclear Regulatory Commission (NRC) for a license to build and operate an Independent Spent Fuel Storage Installation (ISFSI). The proposed ISFSI would store spent nuclear fuel in steel and concrete casks on land in Utah belonging to the Skull Valley Band of Goshute Indians. The facility would be built on an 820-acre site, about 3.5 miles from the Band’s village, pursuant to a lease between the Band and PFS. While most ISFSIs are located at the reactors where the spent nuclear fuel is generated, PFS’s proposed ISFSI would be the first large, away from point-of-generation repository to be licensed by the NRC.
In addition to applying to the NRC for a license, PFS sought two other regulatory approvals. First, it applied to the Bureau of Indian Affairs (BIA) for approval of the Skull Valley Band’s lease of the 820-acre site to PFS. Second, it applied to the Bureau of Land Management (BLM) for a right-of-way to transport the spent nuclear fuel from the main Union Pacific rail line to the ISFSI. PFS proposed two right-of-way options. Its preferred option was to *423 build a new, 32-mile rail spur from the main line that would run along the base of the Cedar Mountains to the ISFSI. PFS’s alternative option was to build an intermo-dal transfer facility, at which spent nuclear fuel would be transferred from railcars to heavy-haul vehicles and then transported to the ISFSI via Skull Valley Road, a two-lane public road.
On September 9, 2005, following a lengthy administrative proceeding in which the petitioners participated, the NRC issued a memorandum and order authorizing its staff to issue a license to PFS to build and operate the ISFSI. On February 21, 2006, after denying Utah’s motion to reopen the record, NRC granted the license. The license, which is specific to the site designated in the proposed lease, permits PFS to store up to 40,000 metric tons of spent nuclear fuel at the facility. Its term is twenty years, with an option to renew for another twenty.
Petitioner Ohngo Gaudadeh Devia (OGD)—an association consisting primarily of members of the Skull Valley Band opposed to construction of a nuclear waste facility on the reservation—timely petitioned for review of the NRC’s decision in this court. So, too, did the State of Utah. PFS and the Skull Valley Band intervened on the side of the NRC.
Subsequent to the filing of the petitions for review, the BLM and the BIA denied the applications that PFS had filed with each agency. The BLM disapproved both of PFS’s requested rights-of-way: the preferred rail route, and the alternative inter-modal transfer facility route. The Bureau rejected the rail line request on the ground that the National Defense Authorization Act for Fiscal Year 2006, Pub.L. No. 109-163, 119 Stat. 3136 (2006), which had been signed into law after publication of the project’s final environmental impact statement, “clearly required” denial. BLM, Record of Decision at 10 (Sept. 7, 2006). Section 384 of the Act designated certain lands, including those described in PFS’s right-of-way application, as wilderness and added them to the National Wilderness Preservation System.
See
National Defense Authorization Act § 384,
For its part, the BIA rejected the Skull Valley Band’s lease of reservation land to PFS for the construction and operation of the ISFSI. Although the local BIA superintendent had conditionally approved the lease in May 1997, the Bureau declared itself unconstrained by the superintendent’s conditional approval. The Bureau based its disapproval on a variety of concerns, including the adequacy of the environmental impact analysis, the relationship of the use of leased lands to neighboring lands, the lack of specialized resources with which to monitor the tenant’s activities and enforce the lease, and the inability to ascertain when spent nuclear fuel might leave the land. See BIA, Record of Decision at 18-29 (Sept. 7, 2006).
The parties advised us of these post-petition developments in their briefs on the merits. We requested supplemental briefing regarding the impact of these developments on justiciability, and we now conclude that the petitions are not ripe for review and should be held in abeyance.
*424 II
The Supreme Court has noted that “[rjipeness is a justiciability doctrine” that is “ ‘drawn both from Article III limitations on judicial power and from prudential reasons for refusing to exercise jurisdiction.’ ”
National Park Hospitality Ass’n v. Dep’t of the Interior,
“In testing whether the facts of a particular case meet th[e] standard of ripeness, we have often applied a two-part analysis, evaluating ‘[1] the fit ness of the issues for judicial decision and [2] the hardship to the parties of withholding court consideration.’ ”
National Treasury Employees Union v. United States,
A
“Among other things, the fitness of an issue for judicial decision depends on whether it is ‘purely legal, whether consideration of the issue would benefit from a more concrete setting, and whether the agency’s action is sufficiently final.’ ”
Atlantic States Legal Found., Inc. v. EPA
Even though the legal issues may be clear, a case may still not be fit for review: [T]he question of fitness does not pivot solely on whether a court is capable of resolving a claim intelligently, but also involves an assessment of whether it is appropriate for the court to undertake the task. Federal courts cannot—and should not—spend their scarce *425 resources on what amounts to shadow boxing. Thus, if a plaintiffs claim, though predominantly legal in character, depends on future events that may never come to pass, or that may not occur in the form forecasted, then the claim is unripe.
McInnis-Misenor,
Resolution of the petitioners’ challenge to the licensing of the storage facility at issue here has all the earmarks of a decision that “we may never need to” make.
National Treasury Employees Union,
The intervenors also insist that “reversal of [the BLM] decision is not required for the project to go forward.” Intervenors’ Supp. Reply Br. 3 n. 5. “That decision,” they argue, “only concerned two transportation options, and ... NRC regulations governing the transportation of spent nuclear fuel would not preclude PFS from accomplishing an intermodal transfer at locations for which no Bureau of Land Management ... approval would be required.” Id. Even if that is true, PFS has not proposed any such option, nor even described one in its briefs. The BLM rejected the only options that PFS did propose, both of which require BLM approval. In the absence of an actual proposal from PFS for an alternative intermo-dal transfer location, it is impossible to know whether or what kind of administrative approval would be required. Such a speculative possibility cannot render the instant petitions ripe for adjudication.
In any event, even if PFS were to find a way to accomplish an intermodal transfer that does not require BLM approval, the BIA’s disapproval of the lease would still block construction and operation of the facility. The license granted by the NRC
*426
is site-specific, authorizing storage only at the location designated in the proposed lease and rejected by the BIA.
See
License for Independent Storage of Spent Nuclear Fuel ¶ 10 (J.A. 1992). Indeed, even the intervenors concede that PFS cannot construct or operate the facility without BIA approval—or judicial reversal of its disapproval. Intervenors’ Supp. Br. 7. The chances of either result, at least at this point, are simply unknown. Put another way, we “find it too speculative whether” the validity of the NRC license is a problem that “will ever need solving.”
Texas,
In sum, the institutional interests in deferring review here are high. Those include avoiding, until the impact on the parties is more certain, the expenditure of judicial resources on a complex, fact-intensive case with a joint appendix of over 4000 pages. But they also include avoiding the issuance of what could effectively become an advisory opinion: if the BIA’s decision is upheld on review (or review is not sought), any opinion regarding the validity of the NRC’s site-specific license could well be moot.
Neither petitioners Utah and OGD, nor respondent NRC, disputes that we have discretion to defer review as a prudential matter. Nor do they object to our holding the case in abeyance'—as compared to dismissing the petitions—pending PFS’s securing the administrative approval (by judicial reversal of disapproval or otherwise) required for it to construct and operate the storage facility. That is what we did under analogous circumstances in
Town of Stratford v. FAA,
Like the FAA’s airport plan, progress on PFS’s spent fuel storage facility awaits uncertain approvals from other agencies, including the agency (BIA) that effectively controls the relevant property. Indeed, this case presents a stronger warrant for abeyance, as those agencies have already denied the necessary approvals.
*427 B
In deciding whether to find this case prudentially unripe and to hold it in abeyance, we must also consider “ ‘the hardship to the parties of withholding court consideration.’ ”
National Treasury Employees Union,
In any event, we find the intervenors’ claim of hardship insubstantial. They are “ ‘not required to engage in, or to refrain from, any conduct’ ” during the time the case is held in abeyance.
Atlantic States Legal Found., Inc.,
Moreover, the gravamen of the interve-nors’ argument “appears to be that mere uncertainty as to the validity of a legal rulfing] constitutes a hardship for purposes of the ripeness analysis.”
National Park Hospitality Ass’n,
“In order to outweigh institutional interests in the deferral of review, the hardship to those affected by the agency’s action must be immediate and significant.”
Action Alliance of Senior Citizens of Greater Philadelphia v. Heckler,
Ill
For the foregoing reasons, we find the petitions for review unripe, and will hold this case in abeyance in accordance with the terms set forth in the accompanying order.
So ordered.
