    Before: ROGERS and JACKSON*, Circuit Judges, and
    SILBERMAN, Senior Circuit Judge.
    Opinion for the Court by Circuit Judge ROGERS.
    ROGERS, Circuit Judge: Adelphia Gateway, LLC, applied
    to the Federal Energy Regulatory Commission for a certificate
    of public convenience and necessity to acquire an existing
    pipeline system in Pennsylvania and Delaware. It also sought
    authorization to construct two short lateral pipeline segments
    extending from the existing pipeline infrastructure it would
    acquire. One of these, the “Parkway Lateral,” would consist of
    a 0.3-mile lateral to an existing meter station that provides
    natural gas service to several transmission companies and
    power plants. Adelphia also sought approval to construct
    facilities necessary to operate the pipeline, including the
    Quakertown Compressor Station in Bucks County,
    Pennsylvania. Together, these acquisitions and improvements
    would comprise the Adelphia Gateway Project (“the Project”).
    The Commission conducted an Environmental
    Assessment analyzing the Project’s safety and its effects on air
    quality, noise, and residential lands near the pipeline. The
    Commission acknowledged that the Project “would contribute

    panel at the time the case was argued but did not participate in the
    preparation of this opinion.
    3
    to global increases in [greenhouse-gas] levels,” but did not
    calculate “the downstream [greenhouse-gas] emissions of the
    southern portion of the Project,” because “the downstream
    emissions from the remainder of the southern portion of the
    Project are not designated to a specific user, and the end use of
    the natural gas is not identified by Adelphia.” Environmental
    Assessment at 132. The Commission also declined to consider
    the upstream impacts of the Project on demand for natural gas,
    which it found to be “outside the scope of this [Environmental
    Assessment].” Id. The Commission considered and rejected
    several alternatives to the Project, and specifically to the
    location of the Quakertown Compressor Station. Id. at 183–84.
    The Environmental Assessment concluded that “if Adelphia
    constructs and operates the proposed facilities in accordance
    with its application and supplements and [the Commission’s]
    recommended mitigation measures,” the project would have
    “no significant impact” on the environment. Id. at 194.
    Petitioners filed comments with the Commission challenging
    the adequacy of the Environmental Assessment and Adelphia’s
    application for a certificate.
    The Commission issued a certificate of public convenience
    and necessity for the Project, finding that Adelphia had
    demonstrated market need for the Project. It relied largely on
    four precedent agreements Adelphia had entered for the
    majority of the Project’s capacity. It rejected commenters’
    arguments that there was insufficient demand in the region to
    support the Project, concluding that commenters had provided
    “no compelling evidence of overbuilding in the face of
    compelling evidence of need in the form of substantial
    customer support.” Certificate Order at 15. The Commission
    concluded that “the benefits that the Adelphia Gateway Project
    will provide to the market outweigh any adverse effects on
    existing shippers, other pipelines and their captive customers,
    and on landowners and surrounding communities.” Id. at 17.
    4
    One member of the Commission dissented. Requests for
    rehearing and a stay of the Certificate Order were denied, and
    the Commission reaffirmed its finding of market need, its
    balancing of adverse impacts and public benefits, and its
    environmental analysis.
    I.
    In their joint brief, petitioners challenge: (1) the
    Commission’s finding of market need for the Project under the
    Natural Gas Act; (2) the sufficiency of the Commission’s
    environmental review under the National Environmental
    Policy Act (“NEPA”); and (3) the constitutionality of the
    Commission’s purported preemption of state and local
    authorities’ ability to protect public health. The Court is
    persuaded that the Commission did not act arbitrarily and
    capriciously.
    This court reviews the Commission’s orders, “including
    those approving certificate applications, under the familiar
    arbitrary and capricious standard” of the Administrative
    Procedure Act (“APA”). Minisink Residents for Env’t Pres. &
    Safety v. FERC, 
    762 F.3d 97
    , 105–06 (D.C. Cir. 2014); see also
    
    5 U.S.C. § 706
    (2)(A). An agency’s compliance with NEPA’s
    requirements is also reviewed under the APA’s arbitrary and
    capricious standard. Sierra Club v. FERC, 
    867 F.3d 1357
    ,
    1367 (D.C. Cir. 2017) (“Sabal Trail”). Thus, with respect to
    petitioners’ challenges under both the Natural Gas Act and
    NEPA, the question is whether the Commission’s Certificate
    and Rehearing Orders were “based on a consideration of the
    relevant factors and whether there has been a clear error of
    judgment.” Minisink, 762 F.3d at 106 (quoting ExxonMobil
    Gas Mktg. Co. v. FERC, 
    297 F.3d 1071
    , 1083 (D.C. Cir.
    2002)). The agency’s decision must “contain ‘sufficient
    discussion of the relevant issues and opposing viewpoints,’”

    To the extent petitioners challenge the Commission’s
    factual findings, this court reviews those findings to ensure
    they are supported by substantial evidence in the record.

     (quoting Colo. Interstate

    standard “requires more than a scintilla, but can be satisfied by
    something less than a preponderance of the evidence,” 
    id.
    (quoting Minisink, 762 F.3d at 108).
    A.
    NEPA provides that “[a]ny proposed ‘major Federal
    action[] significantly affecting the quality of the human
    environment’ triggers in an agency the obligation to prepare an
    Environmental Impact Statement . . . discussing in detail the
    environmental impact of the proposed action, alternatives to
    the action, and other considerations.” Myersville, 783 F.3d at
    1322 (second alteration in original) (quoting 
    42 U.S.C. § 4332
    (C)).     “An agency may preliminarily prepare an
    Environmental Assessment . . . to determine whether the more
    rigorous [Environmental Impact Statement] is required.” 
    Id.
    An environmental impact statement “is unnecessary if an
    agency makes a ‘finding of no significant impact’” on the
    human environment, which “discharges the agency’s NEPA
    documentation obligations.” 
    Id.
    Petitioners contend that both the Commission’s
    environmental impact analysis and its analysis of alternatives
    6
    to the Project were deficient, resulting in an erroneous finding
    of no significant impact. Petitioners maintain that the
    Commission failed to consider (1) upstream effects of
    increased demand for natural gas; (2) downstream effects of
    increased natural gas consumption, specifically the resulting
    greenhouse gas emissions from such consumption; (3) the
    effects on climate change resulting from downstream
    greenhouse-gas emissions; (4) the cumulative impact of the
    Project together with another pipeline project; and (5) the
    environmental effects of the Quakertown Compressor Station
    as compared to alternatives. By circumscribing its analysis in
    these ways, petitioners maintain, the Commission erroneously
    reached a finding of no significant impact rather than
    proceeding to conduct a full environmental impact statement.
    i.   Upstream impacts
    Petitioners contend that the Commission failed to consider
    the possible upstream effects of the Project, particularly
    drilling new natural gas wells to meet the pipeline’s increased
    capacity. The Commission was required to consider these
    upstream impacts only if they were reasonably foreseeable. 
    40 C.F.R. § 1508.1
    (g).        Petitioners point to no evidence
    undermining the Commission’s reasoned conclusion that such
    impacts were not reasonably foreseeable.
    The Commission initially deemed upstream effects on
    drilling to be “outside the scope” of the environmental
    assessment stage of project review.               Environmental
    Assessment at 132. In its Certificate Order, the Commission
    clarified that “the environmental impacts of upstream natural
    gas production are not an indirect effect of the project” because
    “the Adelphia Gateway Project will receive gas from other
    interstate pipelines and there is no evidence that” general
    information about drilling in the region “would help predict the
    7
    number and location of any additional wells that would be
    drilled as a result of any production demand associated with the
    project.” Certificate Order at 99.
    As in Birckhead v. FERC, 
    925 F.3d 510
     (D.C. Cir. 2019),
    petitioners here “have identified no record evidence that would
    help the Commission predict the number and location of any
    additional wells that would be drilled as a result of production
    demand created by the Project.” Id. at 517. Nor do petitioners
    point to any evidence that shippers “would not extract and
    produce [the] gas” even if the Project did not go forward. Id.
    For example, in support of their assertion that upstream
    increases in natural gas drilling were reasonably foreseeable,
    petitioners cite a table showing “[a]ctive, proposed, and
    reported natural gas wells in Pennsylvania.” Appendix 1,
    PennEast Well Drilling Impacts. But petitioners do not explain
    how that location data supports an inference that more wells
    will be needed to support increased demand spurred by the
    Project. And as in Birckhead, petitioners “nowhere claim that
    the Commission’s failure to seek out additional information
    [regarding upstream effects] constitutes a violation of its
    obligations under NEPA.” 925 F.3d at 518. Birckhead governs
    the analysis and forecloses petitioners’ contention that the
    Commission did not adequately consider upstream effects of
    the Project.
    ii.   Downstream impacts
    Greenhouse gas emissions are reasonably foreseeable
    effects of a pipeline project when the project is known to
    transport natural gas to particular power plants. Sabal Trail,
    867 F.3d at 1371–74; accord Birckhead, 925 F.3d at 518.
    Nonetheless, there will inevitably be some limits on the
    foreseeability of emissions, and the court has rejected the
    notion that downstream emissions are always reasonably
    8
    foreseeable effects of a pipeline project. Birckhead, 925 F.3d
    at 518–19. The court “defer[s] to the informed discretion” of
    the Commission, especially “[w]here an issue requires a high
    level of technical expertise.” Del. Riverkeeper, 753 F.3d at
    1313.
    The Commission analyzed the downstream emissions
    impacts of much of the natural gas subscribed in Adelphia’s
    four existing precedent agreements. It determined that any
    other downstream greenhouse gas emissions resulting from the
    Project — including emissions associated with a precedent
    agreement to deliver gas on the Zone South system for further
    transportation on the interstate grid — were not reasonably
    foreseeable because the Commission was unable to identify the
    end users of that natural gas. The Commission’s reasoning was
    sound. It explained that natural gas would be delivered for
    further transportation on the interstate grid to an unknown
    destination and for an unknown end use. It therefore declined
    to estimate emissions associated with those volumes of gas.
    Petitioners maintain that because the vast majority of natural
    gas is ultimately combusted for use as a fuel source, the
    Commission should have used the entire volume of gas to be
    transported on the Project as a basis for estimating emissions
    — a so-called full-burn analysis. That objection is foreclosed
    by Birckhead, which rejected the contention that “emissions
    from downstream gas combustion are, as a categorical matter,
    always a reasonably foreseeable indirect effect of a pipeline
    project.” 925 F.3d at 519. Petitioners also suggest that, even
    if a full-burn analysis was not required, the Commission should
    have assumed that “a certain percentage” of natural gas
    transported on the Project “will be combusted based on
    industry statistics.” Reply Br. 10. That still assumes, contrary
    to Birckhead, that emissions from downstream combustion are
    categorically reasonably foreseeable and that industry averages
    can be applied in any and every case. Further, petitioners make
    9
    no attempt to “identify [a] method . . . that the Commission
    could have used,” EarthReports, Inc. v. FERC, 
    828 F.3d 949
    ,
    956 (D.C. Cir. 2016), to calculate that “certain percentage”
    based on “industry statistics,” Reply Br. 10.
    Petitioners argue that if the information available to the
    Commission was too generalized to permit an estimate of
    emissions, the Commission should have gathered that
    information from Project stakeholders. See Birckhead, 925
    F.3d at 519–20. The Commission did ask Adelphia about the
    destination and end use of the Zone South capacity subscribed
    in the fourth precedent agreement. Adelphia informed the
    Commission that the gas would be delivered for further
    transportation on the interstate grid for an unknown end use.
    Certificate Order at 102 & n.550. Petitioners maintain that this
    exchange did not discharge the Commission’s obligation to “at
    least attempt to obtain the information necessary to fulfill [the
    Commission’s] statutory responsibilities.” Birckhead, 925
    F.3d at 520. Petitioners maintain the Commission should have
    taken the extra step of asking the shipper about the destination
    and end use of the gas. See Pet’rs’ Br. 30–31. But petitioners
    did not raise this argument on rehearing before the
    Commission, instead arguing that the Commission had
    sufficiently specific information to analyze the full extent of
    downstream impacts. Petitioners’ one offhand, unsupported
    comment that the Commission “should have asked for more
    specifics . . . if the information was too general” did not put the
    Commission on notice of the position petitioners now take
    before this court. Pet. for Reh’g at 108. Because this claim
    was not adequately raised before the Commission, the court
    lacks jurisdiction to consider it. See Food & Water Watch v.
    FERC, 
    28 F.4th 277
    , 286 (D.C. Cir. 2022); Birckhead, 925 F.3d
    at 520.
    10
    Petitioners also maintain that, at a minimum, the
    Commission should have calculated the emissions associated
    with the Parkway Lateral, a new 0.3-mile segment of pipeline
    that would connect the existing pipeline with other existing
    natural gas facilities and infrastructure. Consistent with
    Birckhead, 925 F.3d at 520, the Commission sought further
    information from Adelphia about the Parkway Lateral, see
    DPC Data Request from Commission to Adelphia (July 12,
    2018); Adelphia’s Response to DPC Data Request (July 27,
    2018), and learned that the Parkway Lateral “may serve
    Calpine Corporation’s power plants,” but that “no contract or
    precedent agreement exists to ascribe any particular capacity to
    this potential end user,” Environmental Assessment at 132
    n.39. Contrary to petitioners’ suggestion, this case is unlike
    either Sabal Trail, 867 F.3d at 1364, 1371–72, or Food &
    Water Watch, 28 F.4th at 288, as in both cases, precedent
    agreements provided data as to how much gas would be
    transported and thus offered a basis for the Commission to
    estimate emissions. Here, in the absence of any data regarding
    the “amount of capacity that would serve a power plant,” the
    Commission concluded it could not “reasonably quantify or
    foresee the [greenhouse-gas] emission impacts” associated
    with the Parkway Lateral. Reh’g Order at 58. Given the
    deference owed to the Commission’s technical judgments, the
    court cannot conclude this was unreasonable.               Del.
    Riverkeeper, 753 F.3d at 1313.
    iii.   Climate change impacts
    Under 15 U.S.C. § 717r, courts may not consider an
    “objection to the order of the Commission . . . unless such
    objection shall have been urged before the Commission in the
    application for rehearing.” Id. § 717r(b). A challenger’s
    rehearing application must “set forth specifically the ground or
    grounds upon which such application is based.” Id. § 717r(a).
    11
    To satisfy this standard, a party must raise an issue in a petition
    for rehearing with “sufficient clarity regarding the grounds on
    which it urged reconsideration,” Belco Petrol. Corp. v. FERC,
    
    589 F.2d 680
    , 683 (D.C. Cir. 1978), to “alert the Commission
    to particular and possibly remediable problems,” R.I.
    Consumers’ Council v. Fed. Power Comm’n, 
    504 F.2d 203
    ,
    213 (D.C. Cir. 1974).
    The Commission concluded that there was “no
    scientifically-accepted methodology available to correlate
    specific amounts of [greenhouse-gas] emissions to discrete
    changes in” the human environment, Environmental
    Assessment at 172, and rejected the Social Cost of Carbon
    methodology for assessing climate change impacts, Reh’g
    Order at 41–42. The Social Cost of Carbon is a tool that
    quantifies in monetary terms the climate change impact
    resulting from greenhouse-gas emissions. This court has
    upheld similar explanations as sufficient to justify the
    Commission’s refusal to use the Social Cost of Carbon tool.
    See EarthReports, 828 F.3d at 956.
    Petitioners maintain that a Social Cost of Carbon analysis
    was required pursuant to 
    40 C.F.R. § 1502.21
    (c)(4), which
    provides that when “information relevant to reasonably
    foreseeable significant adverse impacts cannot be obtained
    because . . . the means to obtain it are not known,” “the agency
    shall include within the environmental impact statement . . .
    [t]he agency’s evaluation of such impacts based upon
    theoretical approaches or research methods generally accepted
    in the scientific community.” 
    Id.
     Petitioners contend that the
    Social Cost of Carbon tool is one such generally accepted
    methodology. See Pet’rs’ 28(j) Letter at 1–2 (Aug. 19, 2021)
    (citing Vecinos para el Bienestar de la Comunidad Costera v.
    FERC, 
    6 F.4th 1321
     (D.C. Cir. 2021)).
    12
    But they did not argue before the Commission that section
    1502.21(c) required the use of the Social Cost of Carbon tool.
    Their rehearing request referred to the regulation once in a
    footnote, and only in the context of the version of the argument
    petitioners then relied on — that the Commission was wrong
    to reject the Social Cost of Carbon tool on grounds of scientific
    merit. Reh’g Request at 125. That passing reference was not
    enough to “alert the Commission” to the position petitioners
    now take. R.I. Consumers’ Council, 
    504 F.2d at 213
    . On its
    face, 
    40 C.F.R. § 1502.21
    (c) applies only to “environmental
    impact statements,” as opposed to environmental assessments.
    Petitioners never advanced an explanation why the
    Commission was required to use this tool in the less demanding
    environmental assessment context. Because petitioners failed
    to “set forth specifically [this] ground” before the Commission,
    15 U.S.C. § 717r, the court lacks jurisdiction to consider this
    contention, see Food & Water Watch, 28 F.4th at 287, 290.
    iv.   PennEast Pipeline
    “An agency impermissibly ‘segments’ NEPA review
    when it divides connected, cumulative, or similar federal
    actions into separate projects and thereby fails to address the
    true scope and impact of the activities that should be under
    consideration.” Del. Riverkeeper, 753 F.3d at 1313. Whether
    actions should be considered as connected turns on “whether
    one project will serve a significant purpose even if a second
    related project is not built.” City of Bos. Delegation v. FERC,
    
    897 F.3d 241
    , 252 (D.C. Cir. 2018) (quoting Coal. on Sensible
    Transp., Inc. v. Dole, 
    826 F.2d 60
    , 69 (D.C. Cir. 1987)).
    Petitioners acknowledge that the PennEast Pipeline
    Project is now defunct; the Commission vacated the certificates
    it had issued authorizing that project; and this court granted the
    Commission’s motions to dismiss pending actions related to
    13
    that project. Petitioners thus recognize that, in the event of a
    remand to the Commission, “it is no longer necessary for [the
    Commission] to consider PennEast in its NEPA analysis.”
    Pet’rs’ 28(j) Letter at 2 (Mar. 17, 2022).
    The dissolution of the PennEast Pipeline Project has
    rendered harmless any error in the Commission’s failure to
    consider the two projects as connected actions. The “rule of
    prejudicial error,” 
    5 U.S.C. § 706
    , applies “in the NEPA
    context where the proposing agency engaged in significant
    environmental analysis before reaching a decision but failed to
    comply precisely with NEPA procedures.” Nevada, 457 F.3d
    at 90. Even assuming the Commission was required to
    consider the Project and the PennEast Pipeline as connected
    actions, the Commission’s environmental review did not
    prejudice petitioners because the abandonment of the PennEast
    project eliminated the possibility that the projects could have a
    cumulative environmental impact.
    v.   Quakertown Compressor Station and
    Alternatives
    Petitioners finally contend that the Commission did not
    adequately consider the environmental effects of construction
    of the Quakertown Compressor Station as compared to
    alternative options. Petitioners offer a laundry list of purported
    deficiencies in the Commission’s analysis, but the Commission
    took a “hard look” at each point raised by petitioners,
    discharging its obligations under NEPA. Minisink, 762 F.3d at
    111.
    Several of petitioners’ concerns regarding the Quakertown
    Compressor Station revolve around the size of the Quakertown
    site, particularly as compared to other possible sites for the
    compressor station.       The Commission addressed these
    concerns in a reasoned manner. It explained that, while there
    14
    may have been larger possible sites, there was no hard-and-fast
    rule regarding the minimum acceptable site size for a
    compressor station, and that the purported requirements
    petitioners pointed to in agency guidance documents merely
    noted the typical acreage for a compressor station, not the
    minimum required acreage. Certificate Order at 52. The
    Commission also reasoned that any size advantage, including
    increased isolation distances to nearby structures, of alternative
    sites was outweighed by other concerns, including the need for
    “additional compression, resulting in increased air emissions.”
    Reh’g Order at 21–22. Even if the compressor station were
    relocated to one of the alternative sites, the Commission
    pointed out, an above-ground facility would still be needed at
    the Quakertown site. Id.; Environmental Assessment at 184.
    The Commission did not misstate the sizes of the alternative
    sites; it observed that the Salford alternative site offered 2.3
    “[c]onstruction acres,” not 2.3 total acres. Environmental
    Assessment at 184.
    Petitioners raise safety concerns regarding the
    Quakertown site. But their objections — that the Commission
    neglected to “consider land use laws” and improperly permitted
    Adelphia to “rely upon local emergency personnel in the event
    of an incident,” Pet’rs’ Br. 40 — are undeveloped and
    unsupported. The court is unable to discern any basis for
    rejecting the Commission’s safety analysis, which considered
    applicable federal safety standards, the distance from the
    compressor station to existing structures and residences, and
    the mitigation measures to which Adelphia had committed.
    Likewise, the Commission considered and addressed concerns
    about noise pollution and air quality impacts.
    Petitioners’ apprehension regarding the construction of an
    industrial facility near “historic homes” and “prime farmlands
    and wetlands,” Pet’rs’ Br. 41, is understandable. But the
    15
    court’s role “is simply to ensure that the agency has adequately
    considered and disclosed the environmental impact of its
    actions and that its decision is not arbitrary or capricious.”
    Balt. Gas & Elec. Co. v. Nat. Res. Def. Council, 
    462 U.S. 87
    ,
    97–98 (1983). The Commission gave reasoned responses to
    petitioners’ objections that adequately justified its decision not
    to prepare an Environmental Impact Statement.                  See
    Myersville, 783 F.3d at 1322.
    The court’s “role in reviewing an agency’s decision not to
    prepare an [Environmental Impact Statement] is a ‘limited’
    one, ‘designed primarily to ensure that no arguably significant
    consequences have been ignored.’” Myersville, 783 F.3d at
    1322 (quoting TOMAC v. Norton, 
    433 F.3d 852
    , 860 (D.C. Cir.
    2006)). The Environmental Assessment thoroughly considered
    the environmental impacts of the Project and reasonably
    concluded that the Project, which consists mainly of the
    transfer of ownership of existing pipeline, was not likely to
    have a significant impact on the environment. The record
    demonstrates that the Commission was justified in its decision
    to proceed by Environmental Assessment.
    B.
    Petitioners also contend that the Commission’s
    determination of market need for the Project was flawed. Prior
    to filing its application, Adelphia held an open season in
    November and December 2017 to solicit potential interest in
    the pipeline’s service. As a result, Adelphia entered into four
    long-term precedent agreements with natural gas shippers.
    “Precedent agreements are long-term contracts in which gas
    shippers agree to buy the proposed pipeline’s transportation
    services.” Allegheny Def. Project v. FERC, 
    964 F.3d 1
    , 19
    (D.C. Cir. 2020) (en banc). These agreements accounted for
    approximately 76% of the Project’s total natural gas
    16
    transportation capacity. Some of the precedent agreements
    called for the gas subscribed to be delivered to a known end
    user; others called for the gas to be transported to
    interconnections with other interstate pipelines for further
    transportation on the interstate grid.
    Precedent agreements are important, and sometimes
    sufficient, evidence of market need for a pipeline project. See
    Minisink, 762 F.3d at 111 n.10; City of Oberlin v. FERC, 
    937 F.3d 599
    , 605–06 (D.C. Cir. 2019). Petitioners nevertheless
    maintain that the Commission’s determination of public need
    was flawed because the Commission unreasonably relied
    exclusively on Adelphia’s precedent agreements and ignored
    competing evidence demonstrating there was no market need
    for the project. In an August 19, 2021 letter, petitioners
    contend that this court’s decision in Environmental Defense
    Fund v. FERC, 
    2 F.4th 953
     (D.C. Cir. 2021) (“Spire STL”)
    undermines the Commission’s reliance on precedent
    agreements here. In a March 17, 2022 letter, petitioners argue
    that the Commission’s Updated Policy Statement on
    Certification of New Interstate Natural Gas Facilities, 
    178 FERC ¶ 61,107
     (2022) (“Updated Certificate Policy
    Statement”) demonstrates the inadequacy of the Commission’s
    reliance on precedent agreements as evidence of market need.
    Finally, petitioners suggest that the Commission’s market need
    determination failed to account for adverse environmental
    effects.
    First, petitioners’ contention that competing evidence of a
    lack of demand rebutted the existing precedent agreements is
    misplaced. The court has observed that the Commission is not
    ordinarily required “to assess a project’s benefits by looking
    beyond the market need reflected by the applicant’s existing
    contracts with shippers.” Minisink, 762 F.3d at 111 n.10; see
    Myersville, 783 F.3d at 1311; City of Oberlin, 937 F.3d at 605–
    17
    06. And in any event, the Commission addressed the evidence
    petitioners point to as demonstrating sufficient existing
    pipeline capacity, reasonably concluding that concrete
    obligations to purchase natural gas (as demonstrated by the
    precedent agreements) were better evidence of market need
    than the more speculative reports regarding overbuilding and
    future demand relied on by petitioners.
    Spire STL does not cast doubt on that analysis. There, the
    court held that the Commission’s finding of market need was
    arbitrary and capricious in part because “the application was
    supported by only a single precedent agreement” with a shipper
    who “was a corporate affiliate of the applicant who was
    proposing to build the new pipeline.” 2 F.4th at 973. That one
    precedent agreement with an affiliated shipper was
    questionable evidence of market need, the court held, because
    that agreement was reached after the pipeline builder held an
    open season that produced no precedent agreements, id., and
    because petitioners had “identified plausible evidence of self-
    dealing,” id. at 975. Here, by contrast, Adelphia held an open
    season that produced precedent agreements with four different
    shippers for the large majority of the pipeline’s capacity. And
    crucially, most of the Project consists of existing pipeline that
    is merely changing ownership; in that context, the Commission
    could reasonably conclude that precedent agreements were
    especially good evidence of demand for the pipeline’s capacity.
    Nor does the Updated Certificate Policy Statement call
    into question the Commission’s reliance on precedent
    agreements here. Instead, it simply observes that, whereas the
    Commission has sometimes relied “almost exclusively on
    precedent agreements to establish project need” in the past,
    going forward, the Commission will look to other evidence of
    project need as well. 
    178 FERC ¶ 61,107
    , P 54 (2022). The
    Commission made clear that it would not apply the Updated
    18
    Certificate Policy Statement “to pending applications or
    applications filed before the Commission issues any final
    guidance in these dockets,” Order on Draft Policy Statements,
    
    178 FERC ¶ 61,197
    , P 2 (2022). The court has explained that
    an agency’s adoption of a new policy does not render decisions
    reached under an earlier policy arbitrary and capricious.
    Brooklyn Union Gas Co. v. FERC, 
    409 F.3d 404
    , 406 (D.C.
    Cir. 2005).
    Petitioners also contend that the Commission’s balancing
    of “public benefits against the potential adverse consequences”
    of the Project was deficient. Certification of New Interstate
    Natural Gas Pipeline Facilities, 
    88 FERC 61,227
    , 61,745
    (Sept. 15, 1999); see Reply Br. 5–7. In petitioners’ view, the
    Commission cannot have adequately balanced the potential
    “negative impact on the environment or landowners’ property,”
    Myersville, 783 F.3d at 1309, because the Commission
    conducted a “deficient NEPA analysis,” Pet’rs’ Br. 75.
    Because the court concludes that the Commission’s NEPA
    analysis was adequate, this contention necessarily fails as well;
    the Commission’s balancing of public benefits and adverse
    consequences       reasonably     accounted      for   potential
    environmental impacts.
    C.
    Finally, petitioners contend that under the U.S.
    Constitution’s Fifth, Ninth, and Tenth Amendments, the
    Commission interpreted the Natural Gas Act in a manner that
    “unconstitutionally preempt[ed] legitimate state and local
    action that is necessary and appropriate to protect public health,
    safety and welfare.” Pet’rs’ Br. 78. This constitutional claim
    is forfeited. Petitioners are “required to exhaust” even
    “constitutional claims” before the agency, Springsteen-Abbott
    v. SEC, 
    989 F.3d 4
    , 8 (D.C. Cir. 2021), even if the agency does
    19
    not have “the authority to rule on them in the first instance
    during the agency proceedings,” Jarkesy v. SEC, 
    803 F.3d 9
    ,
    19 (D.C. Cir. 2015). Because petitioners did not raise any such
    constitutional argument in requesting rehearing before the
    Commission, see 15 U.S.C. § 717r, the court cannot consider it
    here.
    For the reasons discussed, the petitions for review are
    denied.
