OPINION

We must decide whether a challenge to potential approval of a surface mining permit is ripe for judicial review.

I

Montana Environmental Information Center and Sierra Club (collectively, “MEIC”) sued Tracy Stone-Manning, the Director of the Montana Department of Environmental Quality, in her official capacity. MEIC claims that Stone-Manning will violate duties imposed by the Surface Mining Control and Reclamation Act (“SMCRA”), 30 U.S.C. §§ 1201-1328 , by approving a pending application for Area B of the Rosebud Mine. Invoking the statute’s citizen-suit provision, 30 U.S.C. § 1270 (a)(2), MEIC asked for declaratory and injunctive relief.

A

SMCRA establishes a “cooperative federalism” regime for mining regulation. See Hodel v. Va. Surface Mining & Reclamation Ass’n, 452 U.S. 264, 289 , 101 S.Ct. 2352 , 69 L.Ed.2d 1 (1981). Under SMCRA, Congress “offer[s] States the choice of regulating ... according to federal standards or having state law preempted by federal regulation.” New York v. United States, 505 U.S. 144, 167 , 112 S.Ct. 2408 , 120 L.Ed.2d 120 (1992) (citing Hodel, 452 U.S. at 288 , 101 S.Ct. 2352 ); see also 30 U.S.C. § 1253 .

Montana adopted a regulatory program for non-federal lands, see Mont.Code Ann. §§ 82-4-201 to -254, with the approval of federal authorities, 30 C.F.R. § 926.10 . Montana also “enter[ed] into a cooperative agreement with [the federal government] to provide for State regulation of surface coal mining and reclamation operations on Federal lands within the State.” 30 U.S.C. § 1273 (c); accord 30 C.F.R. § 926.30 .

B

MEIC argued that SMCRA requires Stone-Manning to withhold approval of any permit application until she finds that a cumulative hydrologic impact assessment (“CHIA”) “has been made by the regulatory authority and the proposed operation [“of all anticipated mining in the area”] has been designed to prevent material damage to hydrologic balance outside permit area.” See 30 U.S.C. § 1260 (b)(3). According to MEIC, this CHIA duty “effectively impose[s]” on Stone-Manning three subsidiary duties to: (1) “formulate and apply meaningful, objective material damage criteria that define the conditions that would constitute ‘material damage to the hydro-logic balance’ outside the proposed permit area,” (2) “include among the material damage criteria so formulated and applied each Montana water quality standard applicable to each surface or groundwater resource that the proposed mine may affect,” and (3) “rationally and reasonably find, before approving any application for a new or significantly revised mining permit, that the proposed surface coal mining operation has been designed to prevent material damage to the hydrologic balance outside the proposed permit area.”

MEIC alleged that Stone-Manning and her predecessors “have engaged in a pattern and practice of approving applications for permits to conduct surface coal mining and reclamation operations without” complying with the subsidiary duties. This pattern purportedly shows that Stone-Manning will not follow SMCRA when considering Application 184, the pending application for a permit revision for Area B of the Rosebud Mine. MEIC asked for relief in the form of a declaratory judgment and “[a]n order compelling [Stone-Manning] to comply with” the subsidiary duties.

C

In the district court, Stone-Manning moved for dismissal under Federal Rules of Civil Procedure 12(b)(1) and 12(b)(6). Intervenors moved for judgment on the pleadings under Federal Rule of Civil Procedure 12(c). The district court granted both motions, relying on four independently sufficient reasons, including lack of ripe ness. MEIC timely appealed.

II

MEIC argues on appeal that the district court erred in ruling that its claims are not ripe. It invokes the firm prediction rule that originated in Justice O’Connor’s concurrence in Reno v. Catholic Social Services, 509 U.S. 43, 67 , 113 S.Ct. 2485 , 125 L.Ed.2d 38 (1993) (O’Connor, J., concurring in the judgment). Intervenors contend that MEIC lacks standing to pursue an unripe claim. We first analyze the constitutional limitations on federal jurisdiction and then assess the impact of the firm prediction rule.

A

1

Article III of the Constitution limits the jurisdiction of federal courts to “cases” and “controversies.” U.S. Const, art. Ill, § 2. To enforce this constitutional limitation, the Supreme Court has articulated numerous doctrines that restrict the types of disputes that federal courts will entertain, including standing and ripeness.

Constitutional standing has three components:

Friends of the Earth, Inc. v. Laidlaw Envt’l Srvs. (TOC), Inc., 528 U.S. 167, 180-81 , 120 S.Ct. 693 , 145 L.Ed.2d 610 (2000) (citing Lujan v. Defenders of Wildlife, 504 U.S. 555, 560-61 , 112 S.Ct. 2130 , 119 L.Ed.2d 351 (1992), and Hunt v. Wash. State Apple Adver. Comm’n, 432 U.S. 333, 343 , 97 S.Ct. 2434 , 53 L.Ed.2d 383 (1977)).

A dispute is ripe in the constitutional sense if it “present[s] concrete legal issues, presented in actual cases, not abstractions.” Colwell v. HHS, 558 F.3d 1112, 1123 (9th Cir.2009) (internal quotation marks omitted). In the context of a declaratory judgment suit, the inquiry “depends upon ‘whether the facts alleged, under all the circumstances, show that there is a substantial controversy, between parties having adverse legal interests, of sufficient immediacy and reality to warrant the issuance of a declaratory judgment.’ ” United States v. Braren, 338 F.3d 971, 975 (9th Cir.2003) (quoting Md. Cas. Co. v. Pac. Coal & Oil Co., 312 U.S. 270, 273 , 61 S.Ct. 510 , 85 L.Ed. 826 (1941)).

Ripeness and standing are closely related because they “originate from the same Article III limitation.” Susan B. Anthony List v. Driehaus, — U.S. —, 134 S.Ct. 2334 , 2341 n. 5, 189 L.Ed.2d 246 (2014) (internal quotation marks omitted) (“[T]he Article III standing and ripeness issues in this case boil down to the same question.” (internal quotation marks omitted)); id. at 2345-46 (citing Ohio Civil Rights Comm’n v. Dayton Christian Sch., Inc., 477 U.S. 619 , 625-26 n. 1, 106 S.Ct. 2718 , 91 L.Ed.2d 512 (1986), a ripeness case, as part of a discussion of standing). As a result, we have previously recognized that “in many cases, ripeness coincides squarely with standing’s injury in fact prong.” Thomas v. Anchorage Equal Rights Comm’n, 220 F.3d 1134 , 1138 (9th Cir.2000) (en banc) (“The constitutional component of the ripeness inquiry is often treated under the rubric of standing.... Indeed, because the focus of our ripeness inquiry is primarily temporal in scope, ripeness can be characterized as standing on a timeline”).

2

Regardless of whether we use the verbal formulations developed for standing or the ones developed for ripeness, our analysis is materially unchanged.

a

MEIC asserts that its members will be harmed by mining activity that will occur because Stone-Manning will fail to comply with her CHIA duty. MEIC does not challenge the approval of past applications; it challenges only the anticipated approval of Application 184, which is currently pending. Because the alleged injury has not yet occurred, MEIC is not suing over an “actual” injury. We therefore must determine whether MEIC’s alleged injury is “imminent.”

An injury is imminent “if the threatened injury is ‘certainly impending,’ or there is a “ ‘substantial risk” that the harm will occur.’ ” SBA List, 134 S.Ct. at 2341 (quoting Clapper v. Amnesty Int’l USA, — U.S. —, 133 S.Ct. 1138, 1147 , 1150 n. 5, 185 L.Ed.2d 264 (2013)). MEIC emphasizes that it alleged a pattern or practice of Stone-Manning granting applications without doing proper CHIAs. Assuming arguendo that those allegations establish that Stone-Manning will not do a proper CHIA for Application 184, they do not establish a substantial risk that Stone-Manning will grant the application at all. MEIC’s complaint is devoid of allegations about the likelihood of Stone-Manning approving Application 184.

Such omission is of crucial importance. MEIC argues that its members will be injured by mining operations that have not been subjected to a proper CHIA. But that mining will occur only if Stone-Manning grants the application. MEIC’s complaint did not allege a “substantial risk” of harm because it did not allege a “substantial risk” that Stone-Manning will approve the application.

Even if we assume that MEIC can bring this suit on behalf of its members, see Laidlaw, 528 U.S. at 181 , 120 S.Ct. 693 , its members do not have standing. They have not suffered an “actual or imminent” injury in fact. Id. at 180 , 120 S.Ct. 693 .

b

Analyzing the sufficiency of MEIC’s complaint under the constitutional ripeness standard yields the same answer for the same reasons. See Nat’l Org. for Marriage, Inc. v. Walsh, 714 F.3d 682 , 688-89 & n. 6 (2d Cir.2013) (considering ripeness and standing together because “[constitutional ripeness ... is really just about” the injury-in-fact requirement). Because MEIC does not allege a substantial risk that Stone-Manning will grant the application, we cannot characterize this dispute as “a substantial controversy ... of sufficient immediacy and reality to warrant the issuance of a declaratory judgment.” Braren, 338 F.3d at 975 . This dispute is more an “abstraction[ ]” than an “actual case” because the supposed injury has not materialized and may never materialize. Colwell, 558 F.3d at 1123 ; see also Alcoa, Inc. v. Bonneville Power Admin., 698 F.3d 774, 793 (9th Cir.2012) (“We have dismissed claims that are based solely on harms stemming from events that have not yet occurred, and may never occur, because the plaintiffs raising such claims have not suffered an injury that is concrete and particularized enough to survive the standing/ripeness inquiry.” (internal quotation marks omitted)).

B

To counter the argument that its claims are not ripe, MEIC invokes the firm prediction rule. If the case is ripe under the firm prediction rule, MEIC argues, then it must also have standing to bring the case.

1

The firm prediction rule originated in Justice O’Connor’s concurring opinion in Catholic Social Services . In that case, plaintiffs challenged regulations governing an “alien legalization program.” CSS, 509 U.S. at 45 , 113 S.Ct. 2485 . In the context of this “benefit-conferring rule,” Justice O’Connor explained:

CSS, 509 U.S. at 69 , 113 S.Ct. 2485 (O’Connor, J., concurring in the judgment) (first alteration in original).

Although the Supreme Court did not adopt Justice O’Connor’s standard, we did in Freedom to Travel Campaign v. Newcomb, 82 F.3d 1431, 1436 (9th Cir.1996) (applying the firm prediction rule to a challenge to regulations governing permission to travel to Cuba). See also Immigrant Assistance Project of L.A. Cnty. Fed’n of Labor (AFL-CIO) v. INS, 306 F.3d 842 , 861-62 (9th Cir.2002) (applying the firm prediction rule to a challenge to INS policies and practices governing illegal immigrants’ applications for legalization).

2

Without deciding whether the firm prediction rule applies under the present circumstances, its standards are not met in this case. We can no more make a firm prediction that Stone-Manning will grant the application than we can conclude that there is a substantial risk of her doing so.

Our precedent has not determined exactly how likely an event must be for a court to make a firm prediction that it will occur. Nonetheless, two considerations provide some guidance. First, Justice O’Connor, the creator of the test, equated being able to make a firm prediction that an event would occur with that event being “inevitable.” CSS, 509 U.S. at 69 , 113 S.Ct. 2485 (O’Connor, J., concurring in the judgment) (“If it is ‘inevitable’ that the challenged rule will ‘operat[e]’ to the plaintiffs disadvantage — if the court can make a firm prediction that the plaintiff will apply for the benefit, and that the agency will deny the application by virtue of the rule.... ” (quoting Reg’l Rail Reorganization Act Cases, 419 U.S. 102, 143 , 95 S.Ct. 335 , 42 L.Ed.2d 320 (1974))).

Second, our previous cases have made firm predictions when the plaintiffs injury was nearly certain. In Freedom to Travel Campaign , for example, the challenged regulation permitted educational travel to Cuba only if the proposed travel plans included at least one of two defined activities. 82 F.3d at 1436 . Because the plaintiffs “educational travel plans includefd] neither activity and would be therefore summarily rejected[J its claims [were] ripe under [the firm prediction rule].” Id. Similarly, in Immigrant Assistance Project, we described the possibility that the government would deny plaintiffs’ applications on any ground other than the challenged rule as “remote.” 306 F.3d at 862.

We cannot make a firm prediction about whether or not Stone-Manning will grant the application. MEIC has failed to allege that Stone-Manning’s approval is inevitable or even particularly likely. Indeed, it includes no allegations at all about the likelihood of Stone-Manning approving Application 184.

Ill

For the foregoing reasons, the district court correctly dismissed the case for lack of subject-matter jurisdiction.

AFFIRMED.

. The district court granted a motion to intervene filed by the Crow Tribe of Indians, Great Northern Properties Limited Partnership, Natural Resource Partners L.P., Spring Creek Coal LLC, Western Energy Company, West-moreland Resources, Inc., and International Union of Operating Engineers, Local 400. . Because oral argument has already occurred, we deny MEIC’s motion to expedite oral argument as moot. . We are concerned here with the constitutional aspects of standing and ripeness. We need not analyze prudential standing or prudential ripeness. See Susan B. Anthony List v. Driehaus, - U.S. -, 134 S.Ct. 2334, 2347 , 189 L.Ed.2d 246 (2014) (refusing to "resolve the continuing vitality of the prudential ripeness doctrine”). . MEIC alleges that the Department of Environmental Quality approved Applications 161, 164, 166, 170, 172, 174, 175, 178, 180, and 182, but does not allege anything about the other applications numbered between 161 and 182. We do not know whether the unmentioned applications were approved or even whether they were similar to the mentioned ones. The most that we can infer, then, is that the department approved at least ten of the twenty-two applications in that range. Such frequency, about 45 percent, does not suffice to show a substantial risk that Stone-Manning will approve Application 184. . Because the issue of ripeness is dispositive, we do not address the district court’s alternative bases for dismissal. . MEIC has not argued on appeal, and did not argue below, that it should be permitted to amend its complaint to add allegations that might affect our ripeness analysis. See Rivera v. Peri & Sons Farms, Inc., 735 F.3d 892, 901 (9th Cir.2013) (ruling that arguments not presented in the opening brief are waived); Reyn’s Pasta Bella, LLC v. Visa USA, Inc., 442 F.3d 741 , 749 (9th Cir.2006) (refusing to order the district court to allow amendment to a pleading when the party did not request leave to amend below). Instead, it limited its argument to asking that we reverse and remand for proceedings on the merits of its claims. We cannot do so.
