Opinion for the Court filed by Circuit Judge RANDOLPH.
Thе Bull Mountain Power Company sought permission from a state agency to construct a coal-fired, electric generating plant in Roundup, Montana, in the vicinity of Yellowstone National Park and a federal wilderness area. The state agency issued a permit after reсeiving a letter from an official of the Department of the Interior stating that the power plant would not *3 adversely affect visibility in Yellowstone Park or the wilderness area. The National Parks Conservation Association and other environmental conservation organizatiоns (“National Parks”) sued in district court, claiming that the Interior Department violated the Clean Air Act, 42-U.S.C. §§ 7401-7671q. The district court dismissed the suit on the ground that plaintiffs lacked standing. We reverse.
I.
The proposed Roundup Plant lies between Yellowstone National Park and the UL Bend Wilderness Area. Its proximity tо protected federal lands triggered the Prevention of Significant Deterioration provisions of the Clean Air Act. Under these provisions, which were designed “to preserve, protect, and enhance the air quality in national parks [and] national wilderness areas,” 42 U.S.C. § 7470(2), (3), EPA must forward proposals for the construction of “major emitting facilities” to the “Federal Land Manager” and to the “Federal official” responsible for the areas potentially affected. 42 U.S.C. § 7475(d)(1), (2)(A). The National Park Service manages Yellowstone. The U.S. Fish and Wildlife Service is responsible for the UL Bend Wilderness Area. They, are the Federal Land Managers in this case. The federal official with oversight over both bodies is the Secretary of the Interi- or.
The Clean Air Act does not give these federal officials authority to issue or reject permit applications. But it charges them with “an affirmative responsibility to protect the air quality” in the protected areas, and requires them to “consider ... whether a proposed major emitting facility will have an adverse impact.” § 7475(d)(2)(B). The federal officials fulfill these responsibilities by transmitting to the stаte authority their findings regarding the potential air-quality ramifications of the proposed project. No permit shall issue if “the Federal Land Manager ■ demonstrates to the satisfaction of the State that the emissions from such facility will have an adverse impact on the air quality-related values (including visibility) of such lands.” § 7475(d) (2) (C) (ii). Although the state permitting authority thus retains final decision-making authority,- a federal impact report is not purely advisory. If the state authority chooses to disregard an adverse impact determination, it must — in accordance with federal requirements for state implementation plans — explain its decision in writing and publish the explanation. 40 C.F.R. § 51.307(a)(3); Mont. Admin. R. 17.8.1109(3).
The facts of this case are as follows. On January 14, 2002, the Bull Mountain Power Company applied to the Montana Department of -Environmental Quality (“DEQ”) for a permit for the Roundup Plаnt. On August 12, the DEQ published a draft permit for public comment, having furnished the National Park Service and U.S. Fish and Wildlife Service notice of the pending application. On December 18, following statistical and modeling analysis, the two Federal Land Managers sent a letter and a report formаlly notifying the Montana DEQ that the proposed Roundup Plant would “cause perceptible visibility impairment at” -Yellowstone and UL Bend.
Two days later, Bull Mountain Power voiced its objection to officials at the Interior Department. The company later submitted written comments, arguing that the original federal analysis was flawed because it failed to take into account weather conditions at Yellowstone. (The comments did not mention UL Bend.) In response, the Department’s Air Resources Division conducted further analysis. This only served to reaffirm the original adverse impact conclusion. On January 7, 2003, Air *4 Resources prepared a letter reiterating the initial determination that the Roundup Plant would adversely affect air quality at Yellowstone and UL Bend. On January 10, Assistant Secretary Manson rejected the proposed staff letter and prepared a new letter, withdrawing the December 18 finding of adverse impact. Despite objections from Air Resources staff, and officials of the National Park Service and the Fish and Wildlife Service, the Assistant Secretary sent the withdrawal letter, which represented the final federal action in the matter. On January 31, relying on Interi- or’s reversal of positions, the Montana DEQ approved the Roundup Plant permit application.
National Parks brought suits challenging the permit in Montana state court and in federal district court. In the federal action it claimed that Assistant Secretary Manson violated the Administrative Procedure Act when he withdrew the initial report without adequately discharging his procedural obligation to “consider” the potential adverse impact on air quality in Yellowstone and UL Bend. 42 U.S.C. § 7475(d)(2)(B). In the state litigation, the Montana Suрreme Court ruled in favor of National Parks, vacated the Montana DEQ’s issuance of the Roundup Plant permit and ordered the DEQ to revisit its conclusions.

In order to satisfy Article Ill’s standing requirements, plaintiffs must demonstratе injury-in-fact (concrete and particularized, actual or imminent), caused by the defendant and capable of being redressed by a court order.
Friends of the Earth v. Laidlaw,
A.
National Parks’ complaint alleged that its members regularly use and enjoy Yellowstone and UL Bend. It claims to have suffered a “procedural injury” from the Assistant Secretary’s failure to cоnduct a reasoned determination regarding the proposed plant’s impact on air quality in these areas. Interior does not deny that National Parks has alleged an injury, but it takes issue with the proper characterization of that injury, arguing that National Parks’ claim is simply a chаllenge to the substance of Interior’s action. Regardless whether the alleged injury is procedural or direct, it satisfies the first aspect of the standing test. As an organization dedicated to the conservation of, and whose members make use of, public lands, National Parks suffers а cognizable injury from environmental damage to those lands.
See Sierra Club v. Morton,
The procedural-substantive distinction may still seem to be important because “ ‘[procedural rights are special’: The person who has been accorded a procedural right to protect his concrete interests сan assert that right without meeting all the normal standards for redressability and immedicacy.”
Lujan,
In this case the ultimate source of injury is two steps -remоved from the alleged procedural defect. There is the intra-fed-eral link between the Assistant Secretary’s alleged failure to consider air quality impact and his decision to withdraw the adverse impact letter, and there is the federal-state link between withdrawal of the imрact report and the Montana DEQ’s decision to approve the Roundup Plant permit. The relaxation of procedural standing requirements would excuse National Parks from having to prove the causal relationship regarding the Interior Department’s action, but its burden rеgarding the action of the Montana authorities would not change.
See Ctr. for Law & Educ. v. Dep’t of Educ.,
If the claim is that Interior’s withdrawal of its adverse impact letter was arbitrary and capricious, then.we need only concern ourselves with the connection between the federal action and the outcome of the permitting process in Montаna. On the other hand, if the claim should be viewed as a procedural injury, we need not inquire into whether the procedural defect influenced the final action of the Interior Department. Either option leaves us in essentially the same place. Regardless whether National Parks’.injury is procedural or substantive in nature, the question of standing must turn on the strength of the link between Interior’s action and the ultimate permitting decision of the Montana DEQ.

To satisfy the causation requirement of Article III standing, National Parks had to show a causal link between Interior’s withdrawаl of its adverse impact letter and the Montana DEQ’s decision to

issue the power plant permit.
See Nat’l Wrestling Coaches,
The Montana DEQ has disсretionary authority to conduct an independent evaluation when it receives a federal adverse impact report. Moot. Admin. R. 17.8.1109. But in this case it did not do so. Interior’s withdrawal of its impact letter was virtually dispositive of the state permitting decision. Moot. Dep’t Of Envtl. Quality, Permitting
&
Compliance Div., Record Of Decision For Roundup Power ProjeCt, Jan. 31, 2003,
reprinted in
App. 48-49 (“[T]he federal land managers have withdrawn their finding of adverse visibility impact on nearby mandatory federal Class I areas, so DEQ has not determined that an adverse impact on visibility may result from the proposed action.”). In addition, federal regulations and the Montana air quality regulations are intertwined such that the challenged federal action “alters the legal regime to which the [local] agency action is subject.”
Bennett v. Spear,
The existence of this formal legal relationship undermines Interior’s suggested analogy to
Simon v. Eastern Kentucky Welfare Rights Organization,
C.
As to redressability, although a federal district court ruling in favor of National Parks would not directly determine whether the Roundup Plant will get its permit, the effect of such a ruling would not be far removed. The permitting decision remains open and pending before the Montana DEQ. The Montana Supremе
*7
Court has ordered DEQ to revisit its con-elusions regarding the Roundup Plant permit and to determine anew whether “Bull Mountain established that emissions from its proposed project will not cause or contribute to adverse impact on visibility in the Class I areas at issue.”
Mont. Envtl. Info. Ctr.,
We therefore reverse the judgment of the district court dismissing the action for the lack of standing and remand the case for further proceedings.
So ordered.
