Opinion for the Court filed by Circuit Judge SENTELLE.
The City of Olmsted Falls, Ohio, petitions this Court for review of the Federal Aviation Administration’s (“FAA”) approval of the Record of Decision for a runway improvement project at Cleveland Hopkins International Airport. See Notice of Approval of the Record of Decision for Proposed Development at the Cleveland Hopkins International Airport, Cleveland, Ohio, 65 Fed. Reg. 70374-75 (Nov. 22, 2000). The runway improvement project includes the relocation of one existing runway, the shift and extension of the other parallel runway, and other attendant projects. Olmsted Falls contends that the FAA’s approval was arbitrary and capricious, in violation of: Clean Air Act Section 176(c), 42 U.S.C. § 7506(c); the National Environmental Policy Act, 42 U.S.C. § 4321, et seq. (“NEPA”); and Section 4(f) of the Department of Transportation Act, 49 U.S.C. § 303(c) (“DOT Act”). Olmsted Falls also argues that a supplemental environmental impact statement is required under NEPA. Because the FAA’s approval of the Record of Decision was neither *266 arbitrary nor capricious, and because no further documentation is required under NEPA, we deny the petition for review.
I. Background
Cleveland Hopkins International Airport (“CLE” or “the airport”) is owned by the City of Cleveland, Ohio, and operated by Cleveland’s Department of Port Control. CLE is a major hub for Continental Airlines and as such serves as an important mid-country hub for the National Airspace System as defined by the FAA. The airport is currently served by three active runways: the two parallel runways, which run northeastysouthwest, are separated by only 441 feet, and a third crosswind runway is primarily used by turboprop craft. Due to the extremely narrow separation between the two parallel runways, CLE currently uses one exclusively for arrivals and the other exclusively for departures, reducing capacity and increasing airfield complexity. Studies conducted by the Cleveland Department of Port Control and the FAA indicated that the current runway configuration at CLE is inadequate and modernization is required to alleviate safety risks and to meet future regional and national air travel needs. These studies indicated that by 2003 the existing airport runway system would operate at levels of delay in excess of 12 minutes per aircraft during peak periods.
In 1999, the Cleveland Department of Port Control began preparing a Master Plan Update, a study used to develop and evaluate facilities recommendations consistent with the airport’s character and activity levels. Specifically, the Department of Port Control sought to develop solutions for CLE that would enhance safety, improve efficiency, and lessen the environmental impacts of the airport. After evaluating various airfield and air traffic alternatives, the Department of Port Control issued its Airport Layout Plan. The Airport Layout Plan proposed updating both runways to ensure they meet current FAA design standards and to generally enhance safety, while providing for anticipated demand. The Plan recommended relocating and replacing one of the parallel runways 1241 feet away from the other. The remaining original runway would be shifted 960 feet southwest and extended 2250 feet. This would create greater spacing between the two runways and thus accommodate two parallel taxiways between the runways.
While the Master Plan Update was being prepared by the Department of Port Control, the FAA began the public phase of the environmental review process in May 1998. In October 1999, the FAA issued the draft environmental impact statement (“EIS”) for the implementation of the Master Plan Update and the Airport Layout Plan projects. These projects were the preferred alternative in the draft EIS, and were the subject of written comments by the City of Olmsted Falls (“the City” or “Olmsted Falls”). Following public comment, the FAA released the final EIS in June 2000, and issued the Record of Decision on November 8, 2000. The Record of Decision contains the rationale for all required findings and provides approval for certain projects included in the Department of Port Control’s Airport Layout Plan.
Olmsted Falls filed this petition for review of the Record of Decision on December 29, 2000, pursuant to 49 U.S.C. § 46110(a). Subsequently this Court denied Olmsted Falls’ motion to stay and motion to expedite.
II. Analysis
A. Standing
Before reaching the merits of Olmsted Falls’ petition, we must determine
*267
whether the City has standing before this Court. To satisfy the constitutional requirement of standing, a plaintiff or petitioner must, at an “irreducible, constitutional minimum ... demonstrate that it has suffered a concrete and particularized injury that is: (1) actual or imminent, (2) caused by or fairly traceable to, an act that the litigant challenges in the instant litiga- - tion, and (3) redressable by the court.”
Florida Audubon Soc’y v. Bentsen,
94 . F.3d 658, 663 (D.C.Cir.1996) (en banc) (internal quotation marks and citations omitted);
see Lujan v. Defenders of Wildlife,
In response, the City first contends that it has the necessary “geographic nexus” required to bring an action under “an environmental statute,” in that it is located two miles to the southwest of CLE. However, geographic proximity does not, in and of itself, confer standing on any entity under NEPA or any other statute. Rather, it is the concrete and particularized injury which has occurred or is imminent
due to
geographic proximity to the action challenged that gives rise to Article III standing.
See, e.g., Lujan,
The City further claims that it may represent its citizens, much as a private association could represent its members’ interests. According to the City, “it may properly be inferred that its citizens will use the water from the same watershed into which Abram Creek flows and will breathe the air containing the increased construction and aircraft emissions from the Project undispersed by any significant distance from its points of emission.” The City’s analogy of its representation of its citizens to a private organization’s representation of its members misconceives the very concept of associational standing. “An association only has standing to bring suit on behalf of its
members
when its
members
would otherwise have standing to sue in their own right, the interests it seeks to protect are germane to the organization’s purpose, and neither the claim asserted nor the relief requested requires the participation
*268
of individual members in the lawsuit.”
Fund Democracy, LLC v. SEC,
We need not, however, decide that question. In this Circuit we have found standing for a city suing an arm of the federal government when a harm
to the city itself
has been alleged.
E.g. City of Lafayette, La. v. SEC,
B. FAA Approval of the Record of Decision
Olmsted Falls raises four principal objections to the FAA’s approval of the Record of Decision for the runway improvement projects at CLE. First, the City contends that the FAA has violated the conformity provisions of the Clean Air Act, Section 176(c), 42 U.S.C. § 7506(c), by omitting analysis of nitrogen oxides (NOx) from at least 21 undisclosed construction projects and improperly determining that emissions from the CLE improvement Plan will not exceed the 100 tons NOx per year de minimis threshold established by the Environmental Protection Agency (“EPA”). See 40 C.F.R. § 93.153. Second, arguing that the FAA failed to consider adequately the water quality impacts of the CLE improvement Plan, Olmsted Falls challenges the FAA’s failure to disclose (alleged) non-compliance with the Clean Water Act as a violation of NEPA. Third, *269 the City insists that the alleged degrada-. tion of Abram Creek, caused by a adverting of a portion of the creek to build the relocated runway, constitutes a “use” of parkland requiring “full analysis” under Section 4(f) of the Department of Transportation Act, 49 U.S.C. § 308(c). Finally, Olmsted Falls believes that these alleged errors require a remand for the FAA to perform a supplemental EIS pursuant to NEPA.
These challenges are reviewed under the Administrative Procedure Act’s' (“APA”) arbitrary and capricious standard. This standard is applied to review compliance with NEPA and to determine the adequacy of an EIS,
see Marsh v. Oregon Natural Resources Council,
Notwithstanding the City’s assertion to the contrary, the FAA’s conformity analysis under 42 U.S.C. § 7506(c) is evaluated under the arbitrary and capricious standard set forth in the APA.
See, e.g., Conservation Law Foundation, Inc. v. Busey,
Finally, where the FAA is forecasting capacity and “predicting demand at an airport, the agency’s conclusion is due ‘more deference.’ ”
City of Los Angeles v. FAA,
1. Clean Air Act
Petitioner argues that the FAA failed to adequately disclose and analyze various air quality impacts of the proposed CLE project, in violation of the Clean Air Act. First, it suggests that there are 21 construction-related projects which the FAA omitted from the air quality analysis in the EIS and Record of Decision, including the NOx emissions arising from 6880 days of unreported construction equipment operation. According to Olmsted Falls, these omissions show an additional 5.76 tons of NOx per year could be generated in 2001, 7.57 tons per year possibly in 2002, and 4.84 tons per year potentially in 2003, which would exceed the de minimis threshold of 100 tons NOx per year, and thus violate the Clean Air Act’s conformity provisions. 40 C.F.R. § 93.153; 42 U.S.C. § 7506(c). Because even a small use of various pieces of construction equipment could breach the de minimis threshold, the petitioner contends “there remains an open question as to whether Project emissions will exceed the 100 ton per year NOx de minimis threshold in at least 2001-2003.”
Second, petitioner also contends that the FAA acted arbitrarily and capriciously in determining the baseline for emissions if the CLE redevelopment is not pursued. In essence, Olmsted Falls claims that the FAA overestimated the “natural” growth that would occur without improvements and failed to substantiate its claim that the existing airfield capacity could accommodate this supposed “natural” growth. Because the CLE redevelopment could attract additional air traffic, it is the City’s position that the FAA underestimated the increase in NOx emissions due to the increased capacity arising from the redevelopment project.
Finally, Olmsted Falls asserts that the de minimis exception does not apply to “airport expansions” because in promulgating its final rule implementing the Clean Air Act’s conformity provisions, the EPA stated that “[ljarger projects, such as an airport expansion ... would require a conformity review under all of these de minimis levels.” Determining Conformity of General Federal Actions to State or Federal Implementation Plans, 58 Fed. Reg. 63214, 63228 (Nov. 30, 1993) (emphasis added). As a consequence, it is Olmsted Falls’ position that we must remand and require the FAA to perform a full conformity analysis and supplemental EIS.
In response, the FAA contends that it “complied with CAA requirements, conformed to relevant regulations, and followed FAA’s own guidance documents,” in analyzing construction emissions and “reasonably determined that emissions for the
*271
project, including construction emissions for the project, will not at any time during the construction or implementation of the project, meet or exceed the thresholds established” in the Clean Air Act, and were, therefore,
de minimis.
According to the FAA, the record provides no basis on which to second guess the combined expertise of the FAA and the agencies which reviewed its determinations (the EPA, Ohio EPA, and the Metropolitan Planning Organization). Further, it is the FAA’s position that petitioner has waived this Clean Air Act claim by failing to challenge the FAA’s methodology during the administrative proceedings and never previously arguing that the construction emissions analysis failed to account for these alleged 21 construction projects.
See
49 U.S.C. § 46110(d);
Northwest Airlines, Inc. v. DOT,
In determining whether Olmsted Falls is barred from using these 21 projects to challenge the FAA’s conformity analysis, we must consider whether the FAA had adequately disclosed the 21 projects. It appears that it did. Both the draft EIS and the final EIS disclose all of the projects approved in the Record of Decision, though not all of the activities approved include construction activity. The FAA grouped all of the projects into four major construction activities and estimated NOx emissions from each activity. Both the draft EIS and the final. EIS identified various “independent utility projects” and explained that these projects were “not dependent or interdependent upon the approval of the federal actions” which were the subject of the EIS and would be “completed regardless of the approval and progress of the airport development proposed” in the EIS. Thus these projects were “included within the Baseline (No-Action/No-Build) Alternative as well as within each development alternative.” Yet, at no point after the draft EIS or the final EIS did Olmsted Falls raise claims before the FAA involving these 21 construction projects. Moreover, Olmsted Falls could have requested data and calculations supporting the FAA’s conformity determination under 40 C.F.R. § 93.156, but failed to do so until one day before the Record of Decision was signed. We agree with the FAA that Olmsted Falls, by not challenging the alleged non-inclusion of these 21 projects before the FAA, waived this claim under the Clean Air Act.
Even were we to find that these 21 projects were not adequately disclosed by the FAA, we would conclude that Olmsted Falls has failed to carry its burden of proof of showing that this nondisclosure undermined the FAA’s determination. “ ‘[T]he party challenging an agency’s action as arbitrary and capricious bears the burden of proof.’ ”
Lomak Petroleum, Inc. v. FERC,
Nor is the FAA’s determination of the baseline for natural growth at CLE, and thus the baseline for NOx emissions, arbitrary and capricious. The FAA determined that the airport can accommodate the predicted demand for 2006, based on its current airfield configuration and without the proposed improvements. While there may be delays, FAA defines capacity without reference to delay goals. Here the improvements are to move an
existing
runway, not the addition of a runway, and thus in the FAA’s judgment they will not induce demand. According to the FAA, its forecasts show that “the demand for air travel at CLE is independent of the proposed improvements at the Airport.” In other words, “if you don’t build it, they will come anyway.”
City of Los Angeles v. FAA,
As for the applicability of the
de minimis
exception, we find nothing in the EPA’s rule implementing conformity provisions that prohibits the FAA from applying such an exception. 40 C.F.R. § 93.153. The EPA’s language is merely illustrative, simply acknowledging that “[l]arger projects” would generally exceed the
de min-imis
limitations, and airport expansions
tend to be
larger projects.
2. NEPA
The City contends that the FAA “failed to disclose that the [airport redevelopment] Project would not meet State or Federal water quality standards even though it knew that to be the case,” claiming that the evidence before the FAA “conclusively demonstrates that' water quality would be permanently and adversely affected by the development of the Project.” According to Olmsted Falls these assertions are not a collateral attack on the decisions of state environmental authorities allowing the redevelopment of the airport to go forward, but merely demonstrate that by failing to disclose this (alleged) non-compliance with the Clean Water Act, the FAA has failed to comply with NEPA. The City then explains that a Clean Water Act Section 401 permit, 33 U.S.C § 1341, was not obtained from the local authorities, rather they only granted a waiver, which Olmsted Falls contends they have no power to do under state law. According to the City, although federal law gives the Army Corps of Engineers the power to accept a waiver, 33 C.F.R. 325.2(b)(ii); 40 C.F.R. 121.16(a), it is only “where State law allows such a waiver” and “such power does not exist under Ohio law.” See Ohio Rev.Code § 6111.03P; Ohio AdmimCode § 3745-32-07. The absence of a valid section 401 permit or waiver is alleged to undermine the section 404 permit issued by the Corps of Engineers. 33 U.S.C. § 1344.
Respondents contend that this is essentially a collateral attack on the state environmental Director’s decision to grant a waiver: “To the extent Olmsted disagrees with OEPA’s decision, arguments attacking this decision have no place here.” We agree. Although the petitioner may disagree with the substantive decisions made by the various agencies involved in an EIS, neither NEPA nor any other statute confers jurisdiction on this Court to hear such challenges as part of this proceeding.
See
42 U.S.C. § 4332; 49 U.S.C. § 46110. When reviewing an environmental impact statement, it does not matter whether we agree with the agency’s conclusions. Rather, the EIS acts as a
procedural
safeguard.
See, e.g., City of Los Angeles,
3. Department of Transportation Act Section 4(f)
Petitioner contends that the FAA inadequately analyzed alternatives under Section 4(f) of the Department of Transportation Act, 49 U.S.C. § 303(c), because if it had “it would have ascertained that the anticipated degradation of Abram Creek indeed constitutes a use of parkland and public waters that warrants the full analysis mandated by § 4(f).” “The ‘use’
*274
of parklands within the meaning of section 4(f) includes not only actual, physical takings of such lands but also significant adverse indirect impacts as well.”
Allison v. DOT,
We are, of course, barred by statute from considering this argument if, as the FAA argues, petitioner failed to articulate it before the agency. 49 U.S.C. § 46110(d) (“court may consider an objection to an order of the ... Administrator only if the objection was made in the proceeding conducted by the ... Administrator or if there was a reasonable ground for not making the objection in the proceeding”);
see also Northwest Airlines,
4. Supplemental EIS
Petitioner contends that the claims it makes demonstrate that there are “significant new circumstances or information relevant to environmental concerns” that require a supplemental EIS. 40 C.F.R. § 1502.9(c)(1)(h). The undisclosed construction projects allegedly provide a basis for a supplemental EIS, as does the status of the water quality analyses. The City argues that these “new circumstances” are especially significant where, as here, they go directly to non-compliance with the purpose and substantive requirements of the Clean Air Act and the Clean Water Act.
As respondents point out, much of what Olmsted Falls dubs “new” is not. It was all known to the FAA prior to the issuance of the Record of Decision. A supplemental EIS is only required where new information “provides a
seriously
different picture of the environmental landscape.”
E.g. Wisconsin v. Weinberger,
III. Conclusion
Reading its filings before this Court generously, we hold that the City of Olmsted Falls alleged sufficient harm to itself as a city to have standing. Reaching the merits, we reject each of the petitioner’s claims. The FAA’s determination that NOx emissions from the CLE airport redevelopment would be de minimis was not arbitrary and capricious. Olmsted Falls’ NEPA claim is in essence a collateral at *275 tack on the underlying substance of the local environmental authorities’ determinations. As the FAA was entitled to rely on these determinations, the City’s NEPA claim is without merit. The City’s claim under the DOT Act is barred because it had not been raised previously. Given our findings, the FAA’s decision not to undertake a supplemental EIS was not arbitrary and capricious. The petition for review is ‘ denied.
