    Before: ROGERS and RAO, Circuit Judges, and SENTELLE,
    Senior Circuit Judge.
    Opinion for the Court filed by Circuit Judge RAO.*
    RAO, Circuit Judge: This case concerns whether the
    Federal Energy Regulatory Commission (“FERC” or “the
    Commission”) properly granted NEXUS Gas Transmission,
    LLC (“Nexus”) a certificate of public convenience and
    necessity to construct and operate a natural gas pipeline from
    Ohio to Michigan. After FERC granted Nexus the certificate,
    the City of Oberlin (“City”) petitioned for review claiming,
    among other things, that FERC did not adequately justify its
    reliance on agreements to transport gas ultimately bound for
    export to Canada as evidence of need for the pipeline. See City
    of Oberlin v. FERC (“Oberlin I”), 
    937 F.3d 599
    , 606 (D.C. Cir.
    2019). We agreed that FERC had not explained why
    considering these agreements was lawful and remanded
    without vacatur for FERC to justify its decision. See 
    id.
     at 606–
    07, 611.
    On remand, FERC explained its decision. FERC also
    clarified that it would have granted the certificate even without
    considering the export agreements. The City again petitions for
    review, contending that FERC’s explanations were arbitrary
    *

    the opinion only to the extent that it expresses the alternative
    explanation set forth in Section IV.
    3
    and capricious or contrary to law and that its decision violates
    the Takings Clause. We disagree. FERC’s justification for
    considering the agreements to transport gas bound for export is
    well reasoned and comports with both the Natural Gas Act and
    the Takings Clause. FERC’s alternative explanation that it
    would have granted Nexus a certificate even without
    considering the export agreements also passes muster. We deny
    the petition.
    I.
    A.
    The Natural Gas Act authorizes FERC “to regulate the
    transportation and sale of natural gas in interstate commerce.”
    Oberlin I, 937 F.3d at 602. Section 7, the provision directly at
    issue in this case, governs the construction and operation of
    facilities used to transport or sell gas interstate. See 15 U.S.C.
    § 717f. Section 7 requires natural gas companies to receive a
    certificate from FERC before constructing or operating such a
    facility. Id. § 717f(c)(1)(A). Applications for a certificate are
    granted or denied according to the standard laid out in Section
    7(e). Id. § 717f(c)(1)(B). FERC grants a certificate only if the
    proposed facility “is or will be required by the present or future
    public convenience and necessity.” Id. § 717f(e). Determining
    whether the proposed facility is or will be in the public
    convenience and necessity “requires the Commission to
    evaluate all factors bearing on the public interest.” Atl. Refining
    Co. v. Pub. Serv. Comm’n of N.Y., 
    360 U.S. 378
    , 391 (1959).
    Once a natural gas company has been issued a certificate, it can
    exercise eminent domain as needed to secure property for
    completing the project. 15 U.S.C. § 717f(h).
    FERC has issued a policy statement outlining how it
    determines whether a proposed pipeline is or will be in the
    public convenience and necessity. See Certification of New
    4
    Interstate Nat. Gas Pipeline Facilities (“Certificate Policy
    Statement”), 
    88 FERC ¶ 61,227
     (Sept. 15, 1999), clarified, 
    90 FERC ¶ 61,128
     (Feb. 9, 2000), further clarified, 
    92 FERC ¶ 61,094
     (July 28, 2000). First, FERC determines “whether the
    project can proceed without subsidies from [the company’s]
    existing customers.” Certificate Policy Statement, 88 FERC at
    61,745. If that threshold has been met, FERC balances adverse
    effects that cannot be eliminated against the public benefits of
    the project, an exercise that “is essentially an economic test.”
    
    Id.
     “Adverse effects may include increased rates for preexisting
    customers, degradation in service, unfair competition, or
    negative impact on the environment or landowners’ property,”
    and “[p]ublic benefits may include ‘meeting unserved demand,
    eliminating bottlenecks, access to new supplies, lower costs to
    consumers, providing new interconnects that improve the
    interstate grid, providing competitive alternatives, increasing
    electric reliability, or advancing clean air objectives.’”

    783 F.3d 1301
    , 1309 (D.C. Cir. 2015) (quoting Certificate Policy
    Statement, 88 FERC at 61,748). A common method for
    applicants to demonstrate a public benefit is by showing
    demand for the project with precedent agreements, long-term
    contracts with shippers who would use the pipeline to transport
    natural gas. See Env’t Def. Fund v. FERC, 
    2 F.4th 953
    , 962
    (D.C. Cir. 2021) (citing Certificate Policy Statement, 88 FERC
    at 61,748–49), cert. denied, 
    142 S. Ct. 1668
     (2022).
    Section 7 applies only to “natural gas companies,” defined
    as persons “engaged in the transportation [or sale] of natural
    gas in interstate commerce,” which is in turn defined as
    “commerce between any point in a State and any point outside
    thereof … but only insofar as such commerce takes place
    within the United States.” 15 U.S.C. § 717a(6)–(7). By
    defining interstate commerce to exclude foreign commerce, the
    Natural Gas Act excludes companies that import and export
    5
    gas, but otherwise operate entirely intrastate, from the
    definition of “natural gas company.” See Border Pipe Line Co.
    v. Fed. Power Comm’n, 
    171 F.2d 149
    , 151 (D.C. Cir. 1948).
    Import/export facilities are instead governed by Section 3 of
    the Natural Gas Act, 15 U.S.C. § 717b.1 Section 3, unlike
    Section 7, does not authorize the use of eminent domain to
    construct approved facilities.
    In addition to governing facilities used to import or export
    natural gas, Section 3 governs the imports and exports. All
    persons must get the Secretary of Energy’s approval before
    importing or exporting any natural gas.2 15 U.S.C. § 717b(a).
    1
    Most import/export facilities meet the statutory definition of
    liquefied natural gas (“LNG”) terminals and are thus directly
    governed by Section 3. See 15 U.S.C. §§ 717a(11) (defining LNG
    terminal), 717b(e) (requiring FERC’s approval for the construction
    of LNG terminals). Gas can also be traded across the American-
    Mexican and American-Canadian borders with a pipeline, obviating
    the need for an LNG terminal. Such border-crossing pipelines are not
    mentioned in the Natural Gas Act. Nevertheless, a series of
    Executive Orders and FERC regulations have made border-crossing
    pipelines subject to the same standards as LNG terminals. See Exec.
    Order No. 10,485, 
    18 Fed. Reg. 5,397
     (Sept. 9, 1953) (asserting that
    “executive permission” is required to construct facilities at the border
    used to export and import natural gas in order to ensure “the proper
    conduct of the foreign relations of the United States”); 
    18 C.F.R. §§ 153.5
    (b), 153.15(b) (requiring any person applying for either
    authorization to construct an LNG terminal or authorization to
    construct a border-crossing pipeline to apply for the other
    authorization as well).
    2
    The Secretary of Energy has delegated jurisdiction over the
    construction of border-crossing facilities to FERC and has separately
    delegated the authority to approve imports and exports to the
    Assistant Secretary of Energy for Fossil Energy. Sierra Club v.
    FERC, 
    827 F.3d 59
    , 63 (D.C. Cir. 2016).
    6
    Congress has provided that the import or export of gas to or
    from “a nation with which there is in effect a free trade
    agreement requiring national treatment for trade in natural
    gas[] shall be deemed to be consistent with the public interest.”
    
    Id.
     § 717b(c). Because the Secretary “shall issue” an order
    authorizing the proposed exportation or importation unless it
    finds it “will not be consistent with the public interest,” the
    Secretary must authorize the import or export of gas to a nation
    with which the United States has a free trade agreement. Id.
    § 717b(a).
    B.
    The facts of the City’s dispute with Nexus are fully
    recounted in our earlier decision. See Oberlin I, 937 F.3d at
    603. Nexus filed an application for a certificate of public
    convenience and necessity so that it could build and operate a
    natural gas pipeline from Ohio to Michigan, along with four
    compressor stations along the pipeline’s route. Nexus also
    sought permission to lease capacity from existing pipelines in
    the Appalachian Basin—where much of the transported gas
    would be sourced—and from existing pipelines in Michigan to
    connect the Nexus Project to the Dawn Hub, where gas is
    traded across the American-Canadian border. Nexus secured
    eight precedent agreements accounting for 59% of the
    pipeline’s total capacity. Two of those precedent agreements,
    accounting for 17% of the pipeline’s total capacity, were with
    Canadian companies that serve customers in Canada.
    FERC granted Nexus the certificate, finding that the
    benefits of the project outweighed any adverse effects. See
    Nexus Gas Transmission, LLC, 
    160 FERC ¶ 61,022
     (Aug. 25,
    2017) [Certificate Order]. On the benefits side, FERC credited
    all of the precedent agreements, including those for the export
    of gas to Canada, as evidence of market demand and found that
    7
    without the Nexus Project, existing pipelines had insufficient
    capacity to provide the service contemplated by the Nexus
    Project. 
    Id.
     PP 40–41. FERC found that Nexus had mitigated
    adverse effects by incorporating route variations and that “there
    [was] no evidence that downsizing the project to accommodate
    only the currently-subscribed level of service would result in
    any significant reductions in the project’s impacts on
    landowners and communities.” 
    Id.
     P 37. Specifically, FERC
    analyzed the alternative of a smaller pipeline sized to transport
    the amount of gas contemplated by domestic and export
    precedent agreements and concluded that doing so would only
    very slightly reduce the amount of land the project required. 
    Id.
    PP 43–45. FERC recognized that constructing a larger than
    necessary pipeline would minimize the need for future
    construction that would adversely affect landowners and the
    environment, and decided that this benefit outweighed the
    slightly mitigated impacts of a smaller pipeline. 
    Id.
     P 46. FERC
    concluded that “[b]ased on the benefits the project will provide
    and the minimal adverse impacts on existing shippers, other
    pipelines and their captive customers, and landowners and
    surrounding communities, … the public convenience and
    necessity requires approval of” the Nexus Project. 
    Id.
     P 51.
    On application for rehearing, the City argued that demand
    to use the pipeline to transport gas bound for export could not
    be considered in determining the public convenience and
    necessity under Section 7. Nexus Gas Transmission, LLC, 
    164 FERC ¶ 61,054
     at P 43 (July 25, 2018) [Rehearing Order].
    FERC, in something of a non sequitur, responded by pointing
    out that because much of the gas was bound for domestic
    consumption, the pipeline had to be analyzed under Section 7.
    
    Id.
     P 45.
    The City petitioned for review, raising various objections
    to FERC’s decision under the Administrative Procedure Act
    8
    (“APA”). We rejected most of its arguments. See Oberlin I, 937
    F.3d at 605–11. We agreed, however, that “the Commission
    never explained why it is lawful to credit demand for export
    capacity in issuing a Section 7 certificate to an interstate
    pipeline.” Id. at 606. And although the certificate could
    theoretically have been granted even without crediting the
    export precedent agreements as evidence of a public benefit,
    we could not affirm on that basis because FERC had not
    decided that it would do so. Id. at 607 n.3. We therefore
    “remand[ed] to the Commission for further explanation of
    why—under the Act, the Takings Clause, and the precedent of
    this Court and the Supreme Court—it is lawful to credit
    precedent agreements with foreign shippers serving foreign
    customers toward a finding that an interstate pipeline is
    required by the public convenience and necessity under Section
    7 of the Act.” Id. at 607–08. We did not vacate FERC’s order
    because we found “it plausible that the Commission will be
    able to supply the explanations required, and vacatur of the
    Commission’s orders would be quite disruptive, as the Nexus
    pipeline is currently operational.” Id. at 611.
    This brings us to FERC’s decision under review. On
    remand, FERC elaborated on its reasoning for considering the
    export precedent agreements in its decision to grant the
    certificate. FERC explained that even though some of the gas
    was bound for export, the facility was still a “pipeline
    transporting gas in interstate commerce.” Nexus Gas
    Transmission, LLC, 
    172 FERC ¶ 61,199
     at P 16 (Sept. 3, 2020)
    [Remand Order]. This distinguished the Nexus Project from
    the pipeline at issue in Border Pipe Line Co., 
    171 F.2d at 151
    ,
    where the facility transporting gas bound for export was
    entirely within one state. The Nexus Project met the interstate
    commerce criteria, which did not evaporate simply because
    FERC factored in the export precedent agreements. FERC
    therefore concluded that the Nexus Project was properly
    9
    analyzed as a Section 7 facility, rather than as an export facility
    under Section 3. Remand Order P 16.
    FERC next explained why it credited the export precedent
    agreements as evidence of the Nexus Project’s benefit in its
    Section 7 analysis. FERC emphasized that in deciding whether
    to grant a certificate under Section 7, it “must consider ‘all
    factors bearing on the public interest,’” 
    id.
     P 11 (quoting Atl.
    Refining Co., 
    360 U.S. at 391
    ), and that courts have already
    approved FERC’s crediting precedent agreements as evidence
    of a benefit, 
    id.
     PP 8, 11 (citing Oberlin I, 937 F.3d at 605).
    FERC gave three reasons why export precedent agreements
    had “probative value” when assessing the public convenience
    and necessity. Id. P 11. First, FERC reasoned that Congress has
    determined that exports to free trade nations like Canada are
    beneficial because Section 3 of the Natural Gas Act states that
    such exports are per se consistent with the public interest. Id.
    PP 12–14. Second, FERC described a series of domestic
    benefits that precedent agreements demonstrate will result
    from the pipeline, regardless of where the gas is ultimately
    going to be consumed. Id. PP 17–18. Third, FERC explained
    that the particular export precedent agreements at issue
    demonstrated need for additional capacity to transport gas to
    the Dawn Hub, and that having sufficient capacity to transport
    gas to the Dawn Hub served domestic interests. Id. PP 19–20.
    Finally, FERC decided that considering the export precedent
    agreements did not render granting the certificate violative of
    Takings Clause. Id. PP 22–23. The City again petitioned for
    review.
    II.
    We must set aside FERC’s order “if it is arbitrary and
    capricious or otherwise contrary to law.” Oberlin I, 937 F.3d at
    605. We remanded for FERC to explain why it was lawful to
    10
    credit precedent agreements to transport gas bound for export
    as a benefit under Section 7. Its explanation is rational and
    comports with the Natural Gas Act.
    The City proffers two reasons why FERC’s crediting of
    export precedent agreements was unlawful. First, the City
    maintains that FERC can only consider exports when
    authorizing export facilities under Section 3, and thus could not
    approve the Nexus Project under Section 7 while considering
    the export precedent agreements. Second, the City asserts that
    FERC’s justifications for crediting the export precedent
    agreements were arbitrary and capricious. Neither objection is
    convincing.
    A.
    The City argues that FERC’s decision was contrary to law
    because gas bound for export is not in interstate commerce, and
    thus cannot be considered when deciding whether to grant a
    Section 7 certificate. Instead, if exports are to be considered,
    the City suggests, the project must be analyzed as an export
    facility under Section 3.
    The question concerns the scope of FERC’s authority
    under Section 7. Section 7 authorizes FERC to grant a
    certificate to a “natural-gas company,” 15 U.S.C.
    § 717f(c)(1)(A), which is defined as “a person engaged in the
    transportation of natural gas in interstate commerce, or the sale
    in interstate commerce of such gas for resale,” id. § 717a(6)
    (emphases added). The Act defines “interstate commerce” in a
    way that excludes foreign commerce. See id. § 717a(7). Thus,
    if a pipeline were engaged in foreign, but not interstate,
    commerce, the applicant would not be a “natural-gas
    company,” and therefore the pipeline would be outside FERC’s
    11
    Section 7 authority. See Border Pipe Line Co., 
    171 F.2d at
    150–
    52.
    We agree with FERC’s decision to treat the Nexus Project
    as a Section 7 pipeline, as opposed to a Section 3 export
    facility, even though some of the gas transported in it will
    ultimately be exported. Nexus is indisputably using its
    proposed pipeline to transport gas in interstate commerce.
    Nexus’s application included six precedent agreements to
    transport gas from Pennsylvania and Ohio for sale across state
    lines. See Certificate Order P 9. It is therefore a “natural-gas
    company,” and FERC was therefore correct to analyze its
    application under Section 7 even though some of the gas is
    bound for export.
    FERC’s inclusion of the export precedent agreements in
    its Section 7 analysis did not change that. Nothing in Section 7
    prohibits considering export precedent agreements in the
    public convenience and necessity analysis. Section 7(e) directs
    FERC to grant a certificate to construct a new pipeline
    whenever the pipeline “is or will be required by the present or
    future public convenience and necessity.” 15 U.S.C. § 717f(e).
    And as the Supreme Court has explained, this broad language
    “requires the Commission to evaluate all factors bearing on the
    public interest.” Atl. Refining Co., 
    360 U.S. at 391
    .
    The City asserts that the gas bound for export is not in
    interstate commerce, rendering FERC’s decision to consider
    the export precedent agreements contrary to law. But in the
    Nexus Project the gas bound for export is commingled with the
    gas bound for domestic, interstate use, and “gas commingled
    with other gas indisputably flowing in interstate commerce
    12
    becomes itself interstate gas.” Okla. Nat. Gas Co. v. FERC, 
    28 F.3d 1281
    , 1285 (D.C. Cir. 1994).
    FERC properly considered Nexus’ pipeline under Section
    7 because the gas transported in the Nexus pipeline is
    indisputably in interstate commerce.3 Moreover, FERC could
    lawfully consider the export precedent agreements because an
    assessment of the public convenience and necessity requires a
    consideration of all the factors that might bear on the public
    interest.
    B.
    The City also argues that FERC failed to reasonably justify
    its decision to credit the export precedent agreements as
    evidence of public convenience and necessity. We hold that
    FERC’s consideration of export precedent agreements as part
    of its Section 7 analysis was not only lawful, but also
    adequately justified.
    First, FERC relied on the congressional determination that
    natural gas exports to countries with which the United States
    has a free trade agreement are beneficial to the public. Remand
    Order PP 12–14. Under Section 3(c) of the Natural Gas Act,
    exports to nations with which the United States has a free trade
    agreement for natural gas “shall be deemed to be consistent
    with the public interest.” 15 U.S.C. § 717b(c). The precedent
    agreements Nexus secured were to transport gas bound for
    Canada, a nation with which the United States has a free trade
    agreement for natural gas. Remand Order P 14. Exports to
    Canada are therefore “in the public interest” under Section 3.
    3
    We need not, and do not, decide whether it is within FERC’s
    Section 7 authority to grant a certificate for a pipeline that crosses
    state lines but exclusively transports gas ultimately bound for export.
    13
    FERC reasoned that, in light of this policy, it was “appropriate
    to credit contracts for transportation of gas” bound for Canada
    as evidence of need in its Section 7 analysis. Id. In fact, FERC
    decided that refusing to credit such precedent agreements
    would “thwart[]” “Congress’ directive and intent, as expressed
    in [S]ection 3.” Id. P 15. We would be hard pressed to conclude
    that FERC’s reliance on a clear statutory directive was
    unjustified.
    The City objects that FERC’s analysis was tantamount to
    deciding that a finding of “public interest” under Section 3 was
    interchangeable with a finding of “public convenience and
    necessity” under Section 7, in contravention of both Oberlin I
    and the Natural Gas Act’s granting of eminent domain powers
    under Section 7, but not Section 3. FERC was clear, however,
    that a finding that exporting gas was “not inconsistent with the
    public interest” under Section 3 was not “dispositive of the
    question whether a pipeline proposed to transport that gas … is
    required by the public convenience and necessity” under
    Section 7. Id. Far from conflating the two standards, this means
    that an application could be denied a Section 7 certificate
    despite having export precedent agreements if the overall
    benefits of the proposed pipeline failed to outweigh the overall
    costs. FERC explained that its reliance on Section 3 only
    justified giving “precedent agreements for the transportation of
    gas destined for export the same weight … it gives to other
    precedent agreements.” Id. The export precedent agreements
    are simply one input into the assessment of present and future
    public convenience and necessity.
    Second, FERC explained that myriad domestic benefits
    stem from increasing transportation services for gas shippers
    regardless of where the gas is ultimately consumed. Id. P 17.
    Specifically, FERC explained that Nexus’s proposed pipeline
    would add “additional capacity to transport gas out of the
    14
    Appalachian Basin,” and that the precedent agreements were
    evidence of need for the capacity provided by Nexus’s pipeline.
    Id. P 18. FERC also found that agreements to transport gas on
    Nexus’s pipeline would support the “production and sale of
    domestic gas,” which “contributes to the growth of the
    economy and supports domestic jobs” irrespective of whether
    the gas ended up here or in Canada. Id. The fact that “a portion
    of the gas is [bound] for export” does not diminish the benefits
    that flow from the construction of the pipeline. Town of
    Weymouth v. FERC, 
    2018 WL 6921213
    , at *1 (D.C. Cir. Dec.
    27, 2018). FERC’s explanation of how the export precedent
    agreements evidenced domestic benefits demonstrates “a
    rational connection between the facts found and the choice
    made.” United Airlines, Inc. v. FERC, 
    827 F.3d 122
    , 127 (D.C.
    Cir. 2016) (cleaned up).
    Third and finally, FERC decided that these particular
    precedent agreements with Canadian shippers could be
    considered as evidence that the Nexus Project was needed
    because the agreements were to ship gas to the Dawn Hub.
    Remand Order PP 19–20. Located in Ontario, the Dawn Hub
    “serves as a liquid trading point where supplies move freely to
    and from the United States and Canada.” 
    Id.
     P 19. FERC
    explained that U.S. gas transported to the Dawn Hub increased
    the availability of gas that might be transported through Canada
    and imported back into New York and New England,
    demonstrating future domestic benefits of expanding pipeline
    capacity. 
    Id.
     Because the export precedent agreements
    demonstrated that additional capacity to transport gas to the
    Dawn Hub was needed, they were probative of the Nexus
    Project’s overall benefits.
    The City objects that this reason is arbitrary and capricious
    because the precedent agreements at issue were with foreign
    shippers who would deliver the gas for consumption in Canada,
    15
    not New York and New England. But FERC may consider the
    future public convenience and necessity when granting a
    certificate. See 15 U.S.C. § 717f(e) (allowing FERC to grant a
    certificate when the facility “is or will be required by the
    present or future public convenience and necessity”) (emphasis
    added). In any event, FERC explained that having adequate
    capacity to ship gas to the Dawn Hub had domestic benefits,
    and that the export precedent agreements were evidence of the
    public demand for additional capacity to transport gas from the
    Appalachian Basin to the Dawn Hub. This is an “adequate
    explanation of the agency’s decision.” Oberlin I, 937 F.3d at
    605 (cleaned up).
    We hold that FERC reasonably explained why it
    considered Nexus’ export precedent agreements in granting a
    certificate of public convenience and necessity under Section
    7.
    III.
    In addition to its statutory arguments, the City maintains
    that FERC’s crediting export precedent agreements as a benefit
    runs afoul of the Takings Clause because a pipeline shipping
    gas for export “does not serve a public use.” In its order on
    remand, FERC decided there was no constitutional concern as
    long as its Section 7 determination was properly made. Remand
    Order P 23. We review that constitutional decision de novo.
    See Nat’l Oilseed Processors Ass’n v. Occupational Safety &
    Health Admin., 
    769 F.3d 1173
    , 1179 (D.C. Cir. 2014).
    Under the Takings Clause, for the exercise of eminent
    domain to be legitimate, the property must be seized for “public
    use.” U.S. CONST. amend. V. The Supreme Court has held that
    property taken for a “public purpose” qualifies. Kelo v. City of
    New London, 
    545 U.S. 469
    , 480 (2005). And courts must look
    to the legislature’s judgment about whether a taking is for a
    16
    public purpose. 
    Id.
     “[S]o long as the taking is rationally related
    to a conceivable public purpose,” it is constitutional. Nat’l R.R.
    Passenger Corp. v. Bos. & Me. Corp., 
    503 U.S. 407
    , 422
    (1992) (cleaned up).
    Congress determined that natural gas pipelines that are
    duly certified as being in the public convenience and necessity
    serve a public purpose. See 15 U.S.C. § 717f(h) (granting
    certificate-holding natural gas companies the federal eminent
    domain power). We have already held that judgment is rational.
    See Midcoast Interstate Transmission, Inc. v. FERC, 
    198 F.3d 960
    , 973 (D.C. Cir. 2000) (explaining that, since FERC
    lawfully declared that a pipeline would “serve the public
    convenience and necessity,” it “served a public purpose”). So
    long as FERC’s crediting of export agreements is consistent
    with the Natural Gas Act, it furthers a public purpose consistent
    with the Takings Clause. Cf. 
    id.
     (holding that because it was
    “not improper for FERC to consider the desirability of
    competition” under the Natural Gas Act, the consideration of
    that factor did not violate the Takings Clause).
    In Oberlin I, we found FERC’s Takings Clause
    explanation wanting because it “beg[ged] the unanswered
    question of whether … it is lawful for the Commission to credit
    precedent agreements for export toward a finding that a
    pipeline is required by the public convenience and necessity.”
    937 F.3d at 607. Having now answered that question in the
    affirmative, we hold FERC’s decision does not violate the
    Takings Clause.
    The City recycles its statutory argument that, by
    considering export precedent agreements as a benefit, FERC
    substituted a Section 3 “public interest” finding for a Section 7
    “public convenience and necessity” finding, and that since
    Section 3 does not authorize the use of eminent domain, that
    17
    conflation violated the Takings Clause. But as already
    explained, FERC considered the export precedent agreements
    as one of the many factors in determining the public
    convenience and necessity, and thus did not conflate Sections
    3 and 7. Its decision to grant Nexus the certificate under Section
    7 was proper. The City also asserts that, by arguing that a
    finding of public convenience and necessity under Section 7
    satisfies the Takings Clause per se, FERC is putting itself
    beyond the reach of the Fifth Amendment. But that is not so.
    Rather, Congress has allowed FERC to determine when a
    pipeline meets the public convenience and necessity standard,
    and that determination is subject to judicial review.
    IV.
    We also uphold FERC’s alternative explanation that the
    Nexus Project was in the public convenience and necessity
    even discounting the precedent agreements with Canadian
    companies.4 Remand Order PP 24–28. The domestic precedent
    agreements evidenced a need for 42% of the Nexus Project’s
    capacity, and FERC found that existing pipelines did not have
    enough capacity to ship that amount of gas. Id. P 27. FERC
    explained that, in light of the other benefits of the Nexus
    Project and the small adverse impacts of the project, the need
    demonstrated by the 42% subscription rate was enough to
    justify the pipeline. Id.
    Specifically, FERC found that the Nexus Project was
    needed to alleviate a bottleneck in the capacity to transport gas
    4
    The City suggests that FERC’s justifying the certificate on this
    ground was outside the scope of Oberlin I’s mandate. But “once
    FERC reacquired jurisdiction, it had the discretion to reconsider the
    whole of its original decision.” Se. Mich. Gas Co. v. FERC, 
    133 F.3d 34
    , 38 (D.C. Cir. 1998).
    18
    from the Appalachian Basin and to increase supply to
    Midwestern markets. 
    Id.
     P 25. FERC also explained that
    building a pipeline with excess capacity would enhance the
    pipeline grid for the future. 
    Id.
     On the costs side of the ledger,
    FERC decided that the adverse impacts of the Nexus project
    were small because Nexus was able to acquire 93% of the land
    it needed without resorting to eminent domain. 
    Id.
     P 26. Taking
    all that into account, FERC decided that the Nexus Project was
    in the public convenience and necessity even excluding the
    export precedent agreements. As part of that decision, FERC
    considered but rejected the alternative of approving a pipeline
    sized to transport 42% of the Nexus Project’s capacity—the
    amount required by the domestic precedent agreements. 
    Id.
    P 28 n.73. FERC explained that its initial analysis of a pipeline
    59% of the size of the Nexus Project remained instructive. The
    benefit of avoiding future pipeline construction, and the
    resulting cost and environmental impacts, continued to
    outweigh the small reduction in the burden on landowners that
    a smaller pipeline would yield. 
    Id.
    We find FERC’s independent and alternative reasons for
    approving the pipeline without considering the export
    precedent agreements to be reasonable. There is no floor on the
    subscription rate needed for FERC to find a pipeline is or will
    be in the public convenience and necessity. See Oberlin I, 937
    F.3d at 605 (rejecting the City’s argument that that a 59%
    subscription rate was too low to justify the Certificate). Instead,
    FERC engages in a “flexible inquiry,” considering “a wide
    variety of evidence to determine the public benefits of the
    project.” Id. FERC concluded that existing pipelines could not
    transport the amount of gas required by the domestic precedent
    agreements; that finding, in combination with FERC’s
    reasonable balancing of the Nexus Project’s other benefits and
    adverse impacts, satisfies the APA.
    19
    The City launches a few objections at FERC’s analysis,
    but none render the decision arbitrary and capricious. First, the
    City contends that FERC did not identify which pipelines
    FERC considered in determining that existing pipelines did not
    have enough capacity to transport the gas the Nexus Pipeline
    would move. But FERC identified the pipelines on remand in
    precisely the same manner it did in its initial order—by looking
    at “other pipeline compan[ies’] electronic bulletin boards.”
    Compare Remand Order P 27, with Certificate Order P 40
    n.29. Even assuming that is insufficient, the City did not
    challenge this aspect of FERC’s order in Oberlin I and
    therefore cannot do so now. Nw. Ind. Tel. Co. v. FCC, 
    872 F.2d 465
    , 470 (D.C. Cir. 1989) (“It is elementary that where an
    argument could have been raised on an initial appeal, it is
    inappropriate to consider that argument on a second appeal
    following remand.”).
    Second, the City complains FERC did not analyze a
    hypothetical pipeline specifically sized to transport 42% of the
    Nexus Project’s capacity. But given that FERC had analyzed a
    pipeline sized to transport 59% of the Nexus Project’s capacity,
    there was no need for FERC to start its analysis anew. FERC
    had already found that shrinking the project would barely
    reduce the amount of land that the project would require, and
    that excess capacity could reduce the costs and disruption from
    constructing additional pipelines in the future. Certificate
    Order PP 42–45. FERC’s determination that this reasoning
    applied to a pipeline sized for 42% of the Nexus Project’s
    capacity was reasonable.5
    5
    The City’s other complaints about FERC’s reasoning are
    insubstantial and we reject them without further discussion.
    20
    ***
    Because FERC’s explanation on remand from this court
    was reasonable and because its decision comported with the
    Natural Gas Act and the Takings Clause, we deny the City’s
    petition.
    So ordered.
