The National Wildlife Federation (NWF), an intervenor below, tries to appeal the entry of a consent decree concerning the cleanup of New Bedford Harbor. NWF bills the appeal as one involving critical interpretive questions anent the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), 42 U.S.C. §§ 9601-9675 (1988). There is, however, a prevenient issue; the original parties to the litigation contend that NWF lacks standing to maintain the appeal. Because NWF cannot push past this threshold, we dismiss for lack of appellate jurisdiction (without considering the substantive questions that lie beyond the doorstep).
I. BACKGROUND
The litigation that undergirds this appeal is nearly a decade old. In 1983, two governmental plaintiffs, the United States and the Commonwealth of Massachusetts, acting as natural resources trustees, brought suit for damages under CERCLA § 107, 42 U.S.C. § 9607, in the United States District Court for the District of Massachusetts. The complaint alleged that Aerovox, Inc., Belleville Industries, Inc., and four other defendants bore responsibility for the release of polychlorinated biphenyls into the Acushnet River and New Bedford Harbor, causing injury to natural resources. An amended complaint, filed in March 1984, added claims for recovery of costs to be incurred in remediating the river and harbor.
*111
The subsequent course of the litigation has been much chronicled.
1
We need not retrace the district court’s steps. For the purpose at hand, it suffices to say that, in 1987, NWF moved to intervene as a party plaintiff, premising its motion on the divergence between its views and the views of the plaintiffs as to the appropriate measure of damages for environmental harm. NWF professed concern that, due to this divergence in views, the plaintiffs might settle the pending action too cheaply. On April 27, 1989, the district court granted permissive intervention for the limited purpose of allowing NWF to brief and' argue the following issues: (1) the legal requirements applicable to any proposed consent decree; (2) the appropriate measure of natural resource damages under CERCLA; and (3) the legal requirements for cleanup under CERCLA.
In re Acushnet River & New Bedford Harbor: Proceedings re Alleged PCB Pollution,
On December 18, 1990, the plaintiffs proposed a consent decree memorializing the anticipated settlement of their claims against Aerovox and Belleville. The decree provided that the settling defendants would pay $9,450,000 in response costs and $3,150,000 as' compensation for injuries to natural resources in the harbor area. In exchange for this $12,600,000 cash settlement, the plaintiffs would covenant “not to sue or to take any other civil or administrative action” against Aerovox or Belleville.
On January 7, 1991, the federal government solicited public comment on the proposed decree, 56 Fed.Reg. 535 (1991), as required by CERCLA § 122(d)(2), 42 U.S.C. § 9622(d)(2), and 28 C.F.R. § 50.7 (1990). NWF submitted comments contending that the suggested cash-out settlement would violate CERCLA in two respects. First, NWF argued that “the proposed decree contravened [CERCLA § 122(f)] because EPA has not approved a final response action at the site.” 2 Second, NWF argued that the proposed decree ran afoul of CERCLA § 122(j) because it contemplated that the defendants would obtain covenants not to sue without any assurance that they would “take appropriate actions necessary to protect and restore the natural resources damaged by such release ... of hazardous substances.” 42 U.S.C. § 9622(j)(2)i Unimpressed by NWF’s comments, the plaintiffs pressed the district court to approve the consent decree. On July 16, 1991, the district court, ore tenus, overruled NWF’s objections and entered the decree. This appeal followed.
Because the dispositive issue in this proceeding implicates NWF’s standing to pursue its appeal, we turn immediately in that direction. NWF, an intervenor, is the lone appellant. The plaintiffs (the federal and state governments) and the settling defendants (Aerovox and Belleville) all appear as appellees, the district court having entered final judgment, Fed.R.Civ.P. 54(b), as to all claims against Aerovox and Belleville. The *112 suit remains pending in the court below against other defendants.
II. THE NECESSITY FOR STANDING
Our odyssey through the often Byzantine world of standing is greatly assisted in this instance by the Supreme Court’s opinion in
Diamond v. Charles,
NWF suggests that
Diamond
is not controlling because the original parties here— the federal and state sovereigns, on the one hand, and the settling defendants, on the other hand — remain parties to the appeal. This suggestion is a prime example of a litigant allowing hope to triumph over reason. In
Diamond,
the intervenor also argued that the party on whose side he intervened — the state — remained a party to the litigation, thus keeping the original controversy alive and allowing him to derive the benefit of the state’s standing.
Id.
at 63-64,
So here. In the district court, the plaintiffs were seeking to maximize cleanup efforts; the defendants were hoping to minimize their financial liability. This provided the “adversariness” that rendered the question of NWF’s standing academic.
See id.
at 68-69,
In point of fact, this case presents a stronger argument against continued piggybacking than the
Diamond
case. In
Diamond,
the state, while not itself appealing, had filed a letter of interest making clear that it favored the position that the appellant was endeavoring to advance.
Id.
at 61,
Nor does the clause in the intervention order purporting to grant NWF the right to appeal have any significance on the threshold issue with which we must grapple. Standing is a constitutional precondition to the jurisdiction of a federal court and may not be conferred by judicial fiat upon a party who does not meet the requirements of Article III.
See Diamond,
We have said enough. This case is a Diamond in the rough. Consonant with the Court’s teachings, we rule that an association which has intervened in the trial court and which seeks to prosecute an appeal notwithstanding that the parties on whose side it intervened have eschewed further appeals, must independently pass the test of Article III standing. Applying this precept, NWF can no longer piggyback on the plaintiffs’ interests in this litigation, but must satisfy the requirements for standing if it is to maintain the instant appeal.
III. THE REQUIREMENTS FOR STANDING
Standing poses the potential for a domino effect. If a party lacks standing to bring a matter before the court, the court lacks jurisdiction to decide the merits of the underlying case.
See FW/PBS v. City of Dallas,
The constitutional limitations on standing derive from the requirement that federal courts can act only upon a justiciable case or controversy. U.S. Const. art. III. To satisfy the constitutional imperative, “[a] plaintiff must allege personal injury fairly traceable to the defendant’s allegedly unlawful conduct and likely to be redressed by the requested relief.”
Allen,
In addition to its constitutional dimensions, the doctrine of standing also embraces prudential concerns regarding the proper exercise of federal jurisdiction. To this end, the Court has required “that a plaintiffs complaint fall within the zone of interests protected by the law invoked.”
Allen,
IV. THE METHODOLOGY OF REVIEW
Before shining the light of these teachings on the case at hand, we pause to discuss questions of methodology.
The burden of adducing facts necessary to support standing rests squarely with the party seeking to avail itself of federal jurisdiction. The Court has stated the proposition unequivocally: “It is the responsibility of the complainant clearly to allege facts demonstrating that he is a proper party to invoke judicial resolution of the dispute and the exercise of the court’s remedial powers.”
Warth,
In this instance, the intervenor’s standing was immaterial in the lower court. Once NWF' filed a notice of appeal, however, its standing (or lack thereof) took on critical importance. The appellees promptly moved to dismiss the appeal under 1st Cir.R. 27.1 (which empowers the court of appeals to dismiss an appeal for either lack of jurisdiction or lack of a substantial question). It is necessary, therefore, that we explicate the method and mode of our consideration of such a motion.
In addressing the appellees’ motions to dismiss, we steer by the Court’s beacon. “For purposes of ruling on a motion to dismiss for want of standing, both the trial and reviewing courts must accept as true all material allegations of the complaint, and must construe the complaint in favor of the complaining party.”
Warth,
*115
This formulation does not mean, however, that a court must (or should) accept every allegation made by the complainant, no matter how conclusory or generalized. In connection with run-of-the-mine motions brought under Rule 12(b)(6), a reviewing court is obliged neither to “credit bald assertions, periphrastic circumlocutions, unsubstantiated conclusions, or outright vituperation,”
Correa-Martinez v. Arrillaga-Belendez,
Although the legal standard for reviewing a motion under Rule 12(b)(6) remains constant, the degree of specificity with which the operative facts must be stated in the pleadings varies depending on the case’s context. Thus, there are various classes of cases in which we have required a heightened degree of specificity to withstand a motion to dismiss.
See Garita Hotel Ltd. Partnership v. Ponce Fed. Bank,
This case, too, is elevated above the mine-run. Because standing is fundamental to the ability to maintain a suit, and because the Court has saddled the complainant with the burden of clearly alleging facts sufficient to ground standing, we are of the opinion that, where standing is at issue, heightened specificity is obligatory at the pleading stage. The resultant burden cannot be satisfied by purely conclusory allegations or by a Micawberish reading of a party’s generalized averments. To the contrary, the proponent’s pleadings “must be something more than an ingenious academic exercise in the conceivable.”
SCRAP,
It is with this rubric in mind that we inquire into NWF’s standing to maintain this appeal. 7
V. NWF’S STANDING TO APPEAL
On appeal, NWF identifies two distinct injuries which, it says, are sufficient to sustain standing. First, quoting from its motion to intervene, it alleges that its members “have been and continue to be harmed by the threats and damage to the environment and to natural resources caused by PCBs and other toxics and hazardous substances released into the New Bedford Harbor area.” Second, it alleges harm to its members and other citizens attributable to the government’s failure to comply with certain procedural requirements imposed by CERCLA. We consider these claims separately, after recounting some basic principles.
A. General Principles of Associational Standing.
It is well settled that, under certain circumstances, an unincorporated association may premise standing upon injuries suffered by some or all of its members.
See UAW v. Brock,
In the matter before us, affinity and personal participation are not of particular concern. There is no question that the interests which NWF seeks to safeguard are “germane to the organization’s purpose.”
Hunt,
B. Environmental Harm.
NWF stated in its motion to intervene that it has “79,.000 members and supporters in Massachusetts.” NWF further claimed that its members “use and enjoy, through fishing, swimming, recreational and other uses, the environment and natural resources in the New Bedford Harbor [area],” and that its “members have been and will continue to be harmed by the releases that are the subject of [the] litiga
*117
tion.” NWF has not particularized these conclusory averments in any way. To the contrary, in a manner hauntingly reminiscent of the unsuccessful attempt of another environmental interest group to establish standing in an earlier case,
see Sierra Club v. Morton,
To be sure, unlike the plaintiff in
Morton,
NWF does make a general allegation of actual injury to members. NWF asserts that this generalized allegation of individual harm is sufficient to withstand appellees’ motions to dismiss. We disagree. The averment has no substance: the members are unidentified; their places of abode are not stated; the extent and frequency of any individual use of the affected resources is left open to surmise. In short, the asserted injury is not anchored in any relevant particulars. The intervenor’s papers do not contain an averment, much less a particularized showing, of the type of “concrete injury” that we have said is needed to confer standing in an environmental suit.
CLF/NE,
NWF urges that
SCRAP,
The contrast between SCRAP and the case before us could scarcely be more stark. In SCRAP, unlike here, the association consisted of a discrete number of identified individuals. In SCRAP, unlike here, there was a geographic nexus; all the association’s members resided in' a single, defined metropolitan area, directly affected by the challenged action. 9 In SCRAP, unlike here, economic damage to individual members was manifest. In SCRAP, unlike here, the claimed environmental injury was tied to the particular pursuits of particular persons. We believe these distinctions are of decretory significance. Even under SCRAP’S rather relaxed regime, we cannot find standing in the instant case.
We note, moreover, that the Court has lately limited
SCRAP
to its particular facts, observing that SCRAP’s “expansive expression of what would suffice for [5 U.S.C.] § 702 review ... has never since
*118
been emulated by this Court.”
Lujan,
For these reasons we find NWF’s allegations of environmental injury to be insufficiently specific to sustain a claim of associational standing.
C. Procedural Harm.
The second part of NWF’s quest for standing involves a claim that NWF’s members were deprived of their full right to comment on the consent decree because the plaintiffs failed to comply with certain provisions of CERCLA. NWF argues that, since the consent decree caps the defendants’ payments, it effectively determines the extent and scope of the “plan for remedial action,” thereby nullifying the public’s statutorily guaranteed “opportunity for submission of written and oral comments” prior to “adoption” of such a plan. 42 U.S.C. § 9617(a). As an adjunct to this theme, NWF also argues that by failing to promulgate a final cleanup plan before soliciting public comment on the proposed consent decree, the federal government has undermined the public’s statutory right to provide meaningful comment on the decree prior to “its entry by the court as a final judgment.” 42 U.S.C. § 9622(d)(2)(B).
These somewhat convoluted contentions amount to an overall claim of procedural harm. The claim comprises more cry than wool. While harm resulting from an agency’s refusal to follow statutorily required procedures may in some instances constitute an actual injury sufficient to confer Article III standing,
see Defenders of Wildlife v. Lujan,
1. Previously Addressable Harm. In the first place, NWF appears to have waited too long to premise standing on a theory of procedural harm. Contrary to appellant’s bald-faced assertions before us, its motion to intervene alleged only a claim of environmental harm. The closest it came to an allegation of procedural harm was to say in its motion that:
There also exists, as already has been demonstrated in the proposed decree, the potential for the parties to “bargain away” the interests of NWF and its members, which is to assure that the remedy agreed to is appropriate, protective of NWF and its members, and in compliance with CERCLA.
We do not think that this general statement can be construed to assert a claim of procedural harm to NWF’s members bottomed upon the denial of their right fully and effectively to comment under 42 U.S.C. §§ 9617(a), 9622(d)(2)(B). Rather, the quoted sentence, read in context, is an amplification of one of NWF’s substantive arguments — nothing more. 10
By the same token, NWF’s conduct of the litigation focused exclusively on its claims of environmental harm. Its complaint in intervention sought relief only against the corporate defendants. Its response to the plaintiffs’ motion for entry of the consent decree neither mentioned nor alleged abridgement of members’ rights to comment. At the “decree confirmation” *119 hearing held in the district court, NWF’s counsel made only substantive arguments, eschewing any reference to the incidence of a procedural injury. Because NWF failed in any way to raise the issue of procedural' harm in the court below, notwithstanding that court’s capability to redress such harm (if any existed), NWF cannot now be allowed to predicate appellate standing on that foundation.
2. Absence of Actual Injury. Even if appellant’s claim of procedural harm were properly before us, it would not salvage the day.
There is nothing talismanic about the phrase “procedural harm.” A party claiming under that rúbric is not relieved from compliance with the actual injury requirement for standing.
See, e.g., Munoz-Mendoza,
In this instance, NWF wholly failed to show, or even supportably to allege, that any member suffered a cognizable injury stemming from the supposedly inadequate opportunity to comment. A mere inability to comment effectively or fully, in and of itself, does not establish an actual injury.
11
Here, the actual injury, if there is any, can only stem from the potential for an inadequate cleanup of the New Bedford Harbor area rather than from an alleged impairment of the citizenry’s right to comment. It follows ineluctably that, in order for standing to arise out of procedural harm, NWF must show that its members have suffered, or are imminently in danger of, some distinct and palpable injury flowing from the possibility of an inadequate cleanup.
Cf., e.g., Defenders of Wildlife,
In short, appellant cannot make an end run around the requirement of actual injury. NWF bore a burden, to the extent its standing was dependent on a claim of procedural harm, to limn with fair specificity some concrete nexus between its members and the harbor .area. Without such a nexus, any procedural harm its members suf
*120
fered was common to all members of the public and, therefore, did not rise to the level of stating an individualized claim of harm.
See Warth,
VI. CONCLUSION
To recapitulate, NWF premised its intervention into this remedial action on the divergence between its views and the views of the named plaintiffs concerning the appropriate measure of damages. NWF knew from the start that the district court action might well end in the entry of a decree with which NWF — and NWF alone — disagreed.
12
NWF was on notice that, under the clear mandate of
Diamond v. Charles,
We need go no further. Because NWF has failed, despite ample opportunity, to place in the record specific facts sufficient to support standing, its appeal must be dismissed.
The appeal is dismissed for want of appellate jurisdiction. Costs to appel-lees.
Notes
. The district court has written no less than eight published opinions on various aspects of the litigation.
See In re Acushnet River & New Bedford Harbor: Proceedings Re Alleged PCB Pollution,
. The statute provides that the federal government may grant covenants not to sue to CERC-LA defendants
... if each of the following conditions is met: (A) The covenant not to sue is in the public interest.
(B) The covenant not to sue would expedite response action consistent with the National Contingency Plan....
(C) The [covenantee] is in full compliance with a consent decree under [CERCLA] section 9606 ... (including a consent decree entered into in accordance with this section) for response to the release or threatened release concerned.
(D) The response action has been approved by the [Administrator of the EPA, as the President’s designee].
42 U.S.C. § 9622(f)(1).
. The Court expressly left open the question of whether a party seeking to intervene in the district court must satisfy Article Ill's standing requirements.
Diamond,
. Thomas Wolfe, Look Homeward, Angel, foreword (1929).
. One exception to this general rule is that associations may assert the claims of their members, provided that the members have suffered some distinct and palpable injury. We discuss this exception in greater detail infra.
. Because the pending motions seek dismissal on the basis of the pleadings, they are highly
*115
analogous to motions brought under Fed. R.Civ.P. 12(b). Courts have often treated motions to dismiss for want of standing as motions to dismiss for failure to state a claim, thus bringing them under the rubric of Rule 12(b)(6).
See, e.g., Rental Housing Assoc. of Greater Lynn v. Hills,
. We categorically reject the idea that appellees waived the right to question NWF's standing by not moving for summary judgment in the district court. Standing implicates a court’s ability, consistent with the requirements of Article III, to hear a case. Thus, a defect in standing cannot be waived; it must be raised, either by the parties or by the court, whenever it becomes apparent.
See FW/PBS,
. The Administrative Procedure Act takes a very permissive view of standing, see 5 U.S.C. § 702 (1988), imposing no additional requirements beyond those inherent in Article III.
. To be sure, in moving to intervene, NWF alleged that it had 79,000 "members and supporters” in Massachusetts. But, it did not name even one of them. It did not attempt to distinguish between members and non-members. It did not restrict its claims of harm to its local members. It did not mention whether any members lived in close proximity to the harbor area. When one contrasts a state the size of Massachusetts with the confined geographic area of New Bedford Harbor, it is apparent that residing in Massachusetts, without more, furnishes an inadequate basis for a claim of particularized injury.
. Indeed, we doubt whether this type of procedural harm is consistent with, or falls within, the scope of the permitted intervention — which was limited, at NWF’s own suggestion, to legal issues concerning the measure of damages, the requirements for cleanup, and the requirements for entering a consent decree.
See Acushnet,
. We assume, for argument's sake, but without deciding, that appellant could show some curtailment in this respect. We note, however, that appellant was afforded, and vociferously exercised, a right to comment both administratively (before the federal government moved for entry of the consent decree) and judicially (when the district court held a hearing to consider placing its imprimatur on the decree).
. NWF, it must be recalled, took pains to seek and obtain a right of appeal from the district court.
