    Concurring opinion by Senior Circuit Judge RANDOLPH.
    WILKINS, Circuit Judge: This case again presents the
    seemingly labyrinthine question of whether an agency action
    is final for the purposes of judicial review. The agency action
    before us is a document titled “Guidance on Significant
    Impact Levels for Ozone and Fine Particles in the Prevention
    of Significant Deterioration Permitting Program” (the “SILs
    Guidance”) published on April 17, 2018 by the U.S.
    Environmental Protection Agency (“EPA”), authored by Peter
    Tsirigotis, Director of EPA’s Office of Air Quality Planning
    and Standards.
    3
    Petitioner Sierra Club contends that we can and should
    review the SILs Guidance because it is final agency action
    and prudentially ripe. Respondent EPA counters that this
    Court lacks jurisdiction over the SILs Guidance because it is
    not final agency action, and alternatively, that we should not
    review it because it is not prudentially ripe. Although both
    parties advance arguments on the merits of EPA’s
    interpretation of 
    42 U.S.C. § 7475
    (a)(3) in the SILs Guidance,
    for the reasons detailed herein, we do not reach those issues.
    We hold that the SILs Guidance is not final agency action
    subject to review by this Court under the Clean Air Act
    (“CAA”) as it does not determine rights or obligations and
    does not effectuate direct or appreciable legal consequences
    as understood by the finality inquiry. See 
    42 U.S.C. § 7607
    (b)(1). As such, we dismiss the petition for lack of
    subject-matter jurisdiction under the CAA. We express no
    opinion as to ripeness or the merits.
    I.
    We turn first to the CAA provisions and EPA regulations
    that govern the SILs Guidance.
    Congress enacted the Clean Air Amendments of the CAA
    in 1970 as “a comprehensive national program that made the
    States and the Federal Government partners in the struggle
    against air pollution.” Gen. Motors Corp. v. United States,
    
    496 U.S. 530
    , 532 (1990). The amendments require EPA to
    promulgate national ambient air quality standards
    (“NAAQS”) that limit the concentration of certain pollutants
    allowable in the ambient air people breathe. See 
    42 U.S.C. § 7409
    (a)(1). For each pollutant, primary and secondary
    standards must be set at levels “requisite to protect the public
    health” and “the public welfare,” respectively. 
    Id.
     § 7409(b).
    Each state develops its own state implementation plan (“SIP”)
    4
    containing emission limits and other control measures to
    enforce the NAAQS within the state. Id. §§ 7407(a),
    7410(a)(1)-(2).
    In 1977, Congress amended the CAA to create the
    Prevention of Significant Deterioration (“PSD”) program.
    See 
    42 U.S.C. § 7470-79
    . The PSD program requires major
    emitting facilities 1 to obtain a permit “setting forth emission
    limitations” for a facility prior to construction. 
    42 U.S.C. § 7475
    (a)(1); see Ala. Power Co. v. Costle, 
    636 F.2d 323
    , 378
    (D.C. Cir. 1979). The program requires any applicant for a
    PSD permit to demonstrate that new emissions from the
    proposed project “will not cause, or contribute to, air
    pollution in excess of any (A) maximum allowable increase or
    maximum allowable concentration for any pollutant in any
    area to which this part applies more than one time per year,
    [or] (B) national ambient air quality standard in any air
    quality control region[.]” 
    42 U.S.C. § 7475
    (a)(3). The
    “maximum allowable increase” of an air pollutant is a
    marginal level of increase above the defined baseline
    concentration and is known as the “increment.” 
    75 Fed. Reg. 64,864
    , 64,868 (Oct. 20, 2010).
    Although the permitting process is primarily
    implemented at the state level, with states issuing
    preconstruction permits in accordance with their SIPs and
    federal minimum standards, see 
    42 U.S.C. § 7410
    (a)(1)-(2),
    (l), section 7475(e)(3) authorizes EPA to promulgate
    regulations regarding the ambient air quality analysis required
    under the permit application review. 
    Id.
     § 7475(e)(3)(D).
    1
    A “major emitting facility” is defined as any stationary source that
    emits or has the potential to emit 100 or 250 tons per year
    (depending on the type of source) of any air pollutant. 
    42 U.S.C. § 7479
    (l); see also 
    id.
     § 7479(2)(C) (governing modifications).
    5
    Pursuant to this power, in 1987 EPA promulgated a regulation
    outlining a set of values for states to use in determining what
    level of emissions does “cause or contribute to” a violation
    under section 7475(a)(3). See 
    40 C.F.R. § 51.165
    (b)(2); 
    52 Fed. Reg. 24,672
    , 24,713 (July 1, 1987). The air quality
    concentration values specified in the regulation have become
    known as “significant impact levels,” or SILs, when used as
    part of an air quality demonstration in a permit application.
    See SILs Guidance at 9.
    In 2010, EPA attempted to codify these uses of SILs for
    certain harmful air pollutants, including fine particulate matter
    (“PM2.5”), by amending paragraph (k)(2) of its regulations at
    
    40 C.F.R. §§ 51.166
     and 52.21 and by incorporating PM2.5
    values into its preexisting table of significance values at 
    40 C.F.R. § 51.165
    (b)(2). See 75 Fed. Reg. at 64,864, 64,886,
    64,902. However, after a petition for review was filed, EPA
    asked this Court to vacate and remand the (k)(2) paragraphs
    of both regulations so EPA could address flaws it had
    recognized during the course of litigation. See Sierra Club v.
    EPA, 
    705 F.3d 458
    , 463-64 (D.C. Cir. 2013). In 2013 the
    Court vacated the (k)(2) paragraphs, stating that, on remand,
    “the EPA [might] promulgate regulations that do not include
    SILs or do include SILs that do not allow the construction or
    modification of a source to evade the requirement of the Act
    as do the SILs in the current rule.” 
    Id. at 464
    .
    Following the remand, EPA began developing a new rule
    to address the flaws identified in the 2010 rulemaking, and on
    August 1, 2016, posted online and sought informal public
    comment on a new draft of guidance on the use of SILs. On
    April 17, 2018, EPA issued the SILs Guidance at issue in this
    case with revisions made in response to the public comments.
    The SILs Guidance expressed EPA’s view that permitting
    authorities have the discretion to find sources applying for
    6
    permits and that have individually small impacts exempt from
    the demonstration required by section 7475(a)(3). SILs
    Guidance at 17. Based on statistical analyses and technical
    approaches, the Guidance outlined what the agency believes
    are individually small impacts by identifying recommended,
    non-binding SIL values for the PM2.5 and ozone NAAQS,
    and for the PM2.5 increments. 
    Id. at 15-17
    . The SILs
    Guidance then explained that if a proposed source’s projected
    maximum impact is below the corresponding SIL value, that
    “generally may be considered to be a sufficient demonstration
    that the proposed source will not cause or contribute to a
    violation of the NAAQS.” 
    Id. at 17
    . Permitting authorities
    may use the nationally applicable SILs established in the SILs
    Guidance, but also “have discretion to develop their own SIL
    values” using EPA’s methodology as a model and provided
    the values are properly supported in the record for each
    permitting action or decision in which they are used. 
    Id. at 3
    .
    Essentially, rather than requiring every PSD applicant to
    conduct a full cumulative impact analysis, if a preliminary
    analysis shows “a proposed source’s maximum impact will be
    below the corresponding SIL value,” EPA is open to a finding
    by the state permitting authority that such an impact “will not
    cause or contribute to a violation of the applicable NAAQS or
    PSD increment.” 
    Id. at 17
    . Furthermore, in what EPA refers
    to as a “culpability analysis,” if a cumulative impact analysis
    is done anyway and “predicts a NAAQS violation,” a source
    whose contribution to the violation is less than the SIL for a
    given pollutant may be considered “not culpable for” the
    violation under the Guidance. 
    Id. at 18
    . Permitting
    authorities retain the ability to require additional information,
    and have discretion to find that even if a proposed source’s
    impact is below the relevant SIL value, there has not been a
    sufficient demonstration that the “proposed source will not
    cause or contribute to a violation.” 
    Id.
     The SILs Guidance
    7
    also requires that “[t]he case-by-case use of SIL values should
    be justified in the record for each permit,” and that the record
    for any permitting decision using a SIL recommended in the
    Guidance should fully incorporate the information contained
    in the Guidance, including the technical and legal documents
    used in the permitting process. 
    Id. at 19
    .
    In the SILs Guidance, EPA described the document as
    the first of a two-step approach, explaining it hoped to “first
    obtain experience with the application of these values in the
    permitting program before establishing a generally applicable
    rule.” 
    Id. at 2
    . EPA explained that after seeing how
    “permitting authorities use their discretion to apply and justify
    the application of the SIL values identified” in the Guidance,
    the agency would “assess, refine and, as appropriate, codify
    SIL values and specific applications of those values in a
    future, potentially binding rulemaking.” 
    Id. at 3
    .
    II.
    Section 307(b)(1) of the Clean Air Act, titled
    “Administrative proceedings and judicial review,” provides,
    in relevant part:
    A petition for review of action of the
    Administrator in promulgating [certain
    enumerated nationally applicable actions], or
    any other nationally applicable regulations
    promulgated, or final action taken, by the
    Administrator under this chapter may be filed
    only in the United States Court of Appeals for
    the District of Columbia.
    
    42 U.S.C. § 7607
    (b)(1).
    8
    As the Supreme Court made clear in Harrison v. PPG
    Industries, Inc., section 307(b)(1) is a “conferral of
    jurisdiction upon the courts of appeals[.]” 
    446 U.S. 578
    , 593
    (1980). It is also a venue provision that evinces Congress’
    clear intent that “‘any nationally applicable regulations
    promulgated by the Administrator under the [CAA can] be
    reviewed only in the U.S. Court of Appeals for the District of
    Columbia.’” 
    Id. at 590
     (quoting H.R. Rep. No. 95–294, pp.
    323-324 (1977), which explains that the Committee agreed
    with certain venue proposals of the Administrative
    Conference of the United States also to this effect.); see also
    
    41 Fed. Reg. 56,767
    , 57,768 (Dec. 30, 1976) (stating the
    Administrative Conference’s view that “all such national
    standards” under the CAA shall be reviewed “in the Court of
    Appeals for the District of Columbia Circuit”). However, this
    Court emphasized in Dalton Trucking v. EPA that “under
    section 307(b)(1), subject matter jurisdiction and venue are
    not coterminous.” 
    808 F.3d 875
    , 879 (D.C. Cir. 2015). That
    is, just because an agency action may have national
    applicability does not mean it is final such that it can be
    reviewed immediately by this Court – and vice versa.
    Before explaining why the SILs Guidance is not final
    agency action, we pause to reiterate the proper test for
    finality.
    In United States Army Corps of Engineers v. Hawkes Co.,
    
    136 S. Ct. 1807
     (2016), the Supreme Court affirmed that the
    familiar two-prong test laid out in Bennett v. Spear, 
    520 U.S. 154
     (1997), “remains finality’s touchstone.” See also Cal.
    Cmtys. Against Toxics, 934 F.3d at 635 (citations omitted).
    Under this test, first, the action must “mark the consummation
    of the agency’s decisionmaking process . . . . And second, the
    action must be one by which rights or obligations have been
    determined, or from which legal consequences will flow.”
    9
    Bennett, 
    520 U.S. at 177-78
     (citations and internal quotation
    marks omitted). Each prong of Bennett “must be satisfied
    independently for agency action to be final[.]” Soundboard
    Ass’n, v. FTC, 
    888 F.3d 1261
    , 1267 (D.C. Cir 2018).
    Additionally, “when assessing the nature of an agency action,
    . . . courts should resist the temptation to define the action by
    comparing it to superficially similar actions in the caselaw.
    Rather, courts should take as their NorthStar the unique
    constellation of statutes and regulations that govern the action
    at issue.” Cal. Cmtys. Against Toxics, 934 F.3d at 631.
    Addressing prong one, Petitioner argues the agency’s
    “intention to consider subsequently amending in the Federal
    Register the decisions it already definitively made in the SILs
    Guidance does not render those decisions non-final[.]” Reply
    Br. at 5 (citing Nat’l Envtl. Dev. Ass’n’s Clean Air Project v.
    EPA, 
    752 F.3d 999
    , 1006 (D.C. Cir. 2014)). They point out
    the agency “took comments, made revisions, and produced a
    definitive interpretation of the statute,” arguing those actions
    marked the consummation of EPA’s decisionmaking. 
    Id.
    (citing Whitman v. Am. Trucking Ass’ns, 
    531 U.S. 457
    , 478-
    79 (2001)).
    Respondent argues the SILs Guidance is not the
    consummation of the agency’s process, pointing to the
    document’s disclaimer that it is “neither a final determination
    nor a binding regulation.” SILs Guidance at 19. EPA argues
    the Guidance explicitly states that its issuance is only phase
    one of a two-step process the agency will be undertaking in
    response to the Court’s partial vacatur and remand of the 2010
    rule. Id. at 2. Finally, EPA points to its Fall 2018 regulatory
    agenda, which states that the Guidance was published as a
    first step and that “[b]ased on the information gathered from
    the implementation of [the SILs Guidance] by the permitting
    10
    authorities, EPA will complete a rulemaking action, as
    appropriate.” J.A. 874.
    The parties also disagree whether the SILs Guidance has
    “direct and appreciable legal consequences” as required under
    prong two of Bennett. See 
    520 U.S. at 178
    . Petitioner argues
    the Guidance has “immediate consequences” as it allows
    sources to receive permits “even where it is demonstrated
    they will cause, or contribute to, a violation of the NAAQS or
    increments – so long as their impact is below a SIL.” Pet’r’s
    Br. at 2, 4. They also argue the SILs Guidance resolves the
    “purely legal” question of whether permitting authorities are
    authorized to exempt small air quality impacts under 
    42 U.S.C. § 7475
    (a)(3) and expresses EPA’s definitive position
    on this question of statutory interpretation. 
    Id. at 3
     (internal
    citations and quotations omitted)). They assert the SILs
    Guidance has an “immediate and significant” effect on how
    permitting authorities interpret the PSD permitting
    requirements and will “burden Sierra Club members with
    additional pollution exposure.” 
    Id.
     (citing CSI Aviation
    Servs., Inc. v. U.S. Dep’t of Transp., 
    637 F.3d 408
    , 412 (D.C.
    Cir. 2011)). Finally, Petitioners point to statements by one of
    their standing declarants asserting that permitting authorities
    have begun relying on the proposed and final SILs Guidance.
    
    Id.
     (citing Declaration of Mary Anne Hitt at ¶ 22).
    EPA counters that the SILs Guidance is not final agency
    action as it “does not create a new and binding legal regime.”
    EPA Br. at 29. They argue the SILs Guidance does not
    represent a departure from a prior legal approach as “SILs
    have been used for decades, consistent with EPA regulations.”
    Id. at 23. And that even if the SILs Guidance does break new
    ground, the finality of a legal interpretation does not turn
    solely on whether it is “new” but whether permitting
    authorities are “required to adopt or implement the
    11
    interpretation.” Id. at 28. Second, they argue “the Guidance
    is not binding in any particular permit application review, has
    no legal effect, and does not substitute for or reduce”
    individual permitting authorities’ discretion. Id. at 24. They
    argue the document merely provides technical and legal
    advice and that authorities retain “discretion to use other
    values that may be justified separately,” including values
    lower than those EPA recommends; or they may elect not to
    use SILs at all. Id. at 30 (quoting SILs Guidance at 19-20).
    In response to the Petitioner’s specific examples in the Hitt
    Declaration, EPA responds that “Petitioner does not show that
    the Guidance is written or has been applied in a binding
    manner,” id. at 27, and the fact that some permitting
    authorities may have chosen to use the Guidance does not
    establish that it is legally binding overall, id. at 32. Finally,
    they argue the SILs Guidance does not authorize a
    determination that any specific proposed source will not cause
    or contribute to a violation because the legal requirements of
    the CAA and other EPA regulations, including the
    “demonstration” requirement of 
    42 U.S.C. § 7475
    (a)(3),
    remain wholly unchanged. 
    Id. at 27
    .
    Whether an agency action has “direct and appreciable
    legal consequences” under the second prong of Bennett is a
    “‘pragmatic’” inquiry. Hawkes, 
    136 S. Ct. at 1815
     (quoting
    Abbott Labs. v. Gardner, 
    387 U.S. 136
    , 149 (1967)). And as
    we recently emphasized, courts should “make prong-two
    determinations based on the concrete consequences an agency
    action has or does not have as a result of the specific statutes
    and regulations that govern it.” Cal. Cmtys. Against Toxics,
    934 F.3d at 637. When deciding whether guidance statements
    meet prong two, this Court has considered factors including:
    (1) “the actual legal effect (or lack thereof) of the agency
    action in question on regulated entities”; (2) “the agency’s
    characterization of the guidance”; and (3) “whether the
    12
    agency has applied the guidance as if it were binding on
    regulated parties.” National Mining Ass’n v. McCarthy, 
    758 F.3d 243
    , 253 (D.C. Cir. 2014).
    In Hawkes, the Court held, in part, that the agency
    determination at issue had direct and appreciable legal
    consequences (or actual legal effect) because if petitioners
    failed to heed the determination they did so at the risk of
    significant criminal and civil penalties under the statutory
    regime. 
    136 S. Ct. at 1815
    . Hawkes relied on a long line of
    cases illustrating a pragmatic approach to finality by focusing
    on how agency pronouncements actually affect regulated
    entities. 
    Id.
     (citing Sackett v. EPA, 
    566 U.S. 120
    , 126 (2012)
    (holding that the agency action at issue satisfied Bennett
    prong two because it exposed petitioners to double penalties
    in a future enforcement proceeding and limited their ability to
    obtain a certain type of permit); Abbott Labs., 
    387 U.S. at 152
    (holding that the action at issue had a “sufficiently direct and
    immediate” impact on petitioners, such that judicial review
    was appropriate, because noncompliance risked “serious
    criminal and civil penalties”); Frozen Food Express v. United
    States, 
    351 U.S. 40
    , 44 (1956) (same)).
    We have continued to affirm this approach, most recently
    in Valero Energy Corporation v. EPA, 
    927 F.3d 532
     (D.C.
    Cir. 2019) and California Communities, 934 F.3d at 637. In
    Valero, we held, in part, that after analyzing the letter in
    question under the relevant statutory regime (1) the guidance
    imposed no obligations, prohibitions, or restrictions; (2) it put
    no party to the choice between costly compliance and the risk
    of a penalty of any sort; (3) EPA acknowledged at oral
    argument that the guidance had no independent legal
    authority; and (4) the relevant statute provided regulated
    parties a mechanism by which to challenge any EPA action
    13
    that was premised on the statutory interpretation that the
    guidance advanced. 927 F.3d at 536-39.
    In California Communities, we found, in part, that the
    memo at issue was not final where (1) neither EPA nor
    regulated sources could rely on it as independently
    authoritative in any proceeding; (2) state permitting
    authorities faced no penalty or liability of any sort in ignoring
    it; and (3) state permitting authorities and regulatory
    beneficiaries had clear avenues by which to challenge a
    permitting decision adopting the reasoning of the memo. 934
    F.3d at 638.
    Assessing the SILs Guidance under Hawkes and in
    accordance with Valero and California Communities, we find
    it is not final agency action. Given the specific nature of the
    statutory regime, the SILs Guidance imposes no obligations,
    prohibitions or restrictions on regulated entities, does not
    subject them to new penalties or enforcement risks, preserves
    the discretion of permitting authorities, requires any
    permitting decision relying on the Guidance be supported
    with a robust record, and does not prevent challenges to
    individual permitting decisions. The SILs Guidance is not
    sufficient to support a permitting decision – simply quoting
    the SILs Guidance is not enough to justify a permitting
    decision without more evidence in the record, including
    technical and legal documents. See SILs Guidance at 19. It is
    also not necessary for a permitting decision – permitting
    authorities are free to completely ignore it. See id. at 19-20.
    As such, we find the SILs Guidance does not result in “direct
    and appreciable legal consequences” as required under prong
    two of Bennett. See 
    520 U.S. at 178
    .
    Paramount in this decision is the amount of discretion
    permitting authorities retain after publication of the SILs
    14
    Guidance. In Catawba County, this Court found an agency
    memo nonfinal where it did not “impose binding duties on
    states or the agency. . . . [but] merely clarifie[d] the states’
    duties under the [CAA] and explain[ed] the process EPA
    suggests,” noting those views were open to revision. 
    571 F.3d 20
    , 33-34 (D.C. Cir. 2009). Similarly, the SILs
    Guidance imposes no obligations, prohibitions, or restrictions,
    and “compels action by neither the recipient nor the agency.”
    Holistic Candlers & Consumers Ass’n v. FDA, 
    664 F.3d 940
    ,
    944 (D.C. Cir. 2012); see also Valero, 927 F.3d at 536.
    During this initial information-gathering phase, permitting
    authorities can choose to reference the values outlined in the
    SILs Guidance, to develop and justify their own SILs, or even
    to ignore the Guidance entirely. See SILs Guidance at 19-21.
    The SILs Guidance explicitly preserves state discretion
    regarding what degree of modeling or analysis may be
    necessary for each petition and does not require states to
    review their programs or take any proactive action in
    response. See SILs Guidance at 3. The states have not been
    given “marching orders” and are not expected to “fall in line,”
    see Appalachian Power Co., 
    208 F.3d 1015
    , 1023 (D.C. Cir.
    2000) (finding guidance final where it required state
    permitting authorities to search for deficiencies in existing
    programs and to take action if any were found, 
    id. at 1022
    ),
    but retain discretion to utilize the SILs Guidance or maintain
    the status quo in their individual permitting programs.
    Petitioner also points to a line of cases which incorporate
    the analysis of Ciba-Geigy, 
    801 F.2d 430
     (D.C. Cir. 1986), a
    ripeness case which this Court has described as
    “complementary” to Bennett. Reckitt Benckiser, Inc. v.
    E.P.A., 
    613 F.3d 1131
    , 1137 (D.C. Cir. 2010). These cases
    focus on whether the agency action at issue (usually a
    preenforcement letter threatening action if the regulated entity
    does not change a certain behavior) has a practical effect on
    15
    regulated parties, even if the action itself has no formal legal
    force. See, e.g., CSI Aviation Servs., Inc., 
    637 F.3d at 412
    (concluding the agency action was final because it “imposed
    an immediate and significant practical burden” by forcing the
    company to choose between conforming to the agency’s
    demand or facing civil and criminal penalties); Nat’l Ass’n of
    Home Builders v. Norton, 
    415 F.3d 8
    , 15 (D.C. Cir. 2005)
    (“Finality resulting from the practical effect of an ostensibly
    non-binding agency proclamation is a concept we have
    recognized in the past.”); Clean Air Council v. Pruitt, 
    862 F.3d 1
    , 4, 7 (D.C. Cir. 2017) (finding a stay of portions of a
    rule final agency action because it relieved regulated parties
    of any obligation to comply with monitoring requirements,
    eliminating the threat of civil penalties, citizens’ suits, fines,
    and imprisonment for noncompliance). However, the SILs
    Guidance is nonfinal even if we look to this line of cases and
    considerations as it does not subject regulated entities to the
    same level of practical consequences present in Ciba-Geigy or
    CSI Aviation. See also Valero, 927 F.3d at 537 (“We need
    not explore the potential tension between those lines of
    decisions because the EPA document is nonfinal even if we
    take into account its practical consequences.”).
    As in Valero, EPA is not using the SILs Guidance to
    “flex[] its regulatory muscle” or to present regulated entities
    with the “painful choice between costly compliance and the
    risk of prosecution at an uncertain point in the future[.]” CSI
    Aviation Servs., 
    637 F.3d at 412-13
    . Nor does the SILs
    Guidance “impose obligations by chicanery – disclaiming
    legal force and effect but nonetheless ‘read[ing] like a
    ukase.’” Valero, 927 F.3d at 537 (quoting Appalachian
    Power, 
    208 F.3d at 1023
    ). The SILs Guidance by itself does
    not expose any regulated entity to the possibility of an
    enforcement action or to enhanced fines or penalties. See
    Sackett, 
    566 U.S. at 126
    ; see also National Mining Ass’n, 758
    16
    F.3d at 252 (holding that a guidance statement was not final
    action, in part, because “[a]s a matter of law, state permitting
    authorities . . . may ignore EPA’s . . . Guidance without facing
    any legal consequences[]”). The document merely provides
    guidance that permitting authorities may use on a “case-by-
    case” basis. SILs Guidance at 19. As such, we find it does
    not beget the same practical consequences as the targeted pre-
    enforcement letters in CSI Aviation and Ciba-Geigy and is not
    final agency action under prong two of Bennett.
    Since a finding that the second prong of Bennett is
    lacking is enough to render an agency action non-final, we
    need not reach Petitioner’s arguments under the first prong.
    See Soundboard, 888 F.3d at 1267; see also Sw. Airlines Co.
    v. U.S. Dep’t of Transp., 
    832 F.3d 270
    , 275 (D.C. Cir. 2016).
    The         petition       is       hereby        dismissed.
    WILKINS, Circuit Judge, concurring: In order to prevent
    a patchwork of regional interpretations of nationally
    applicable agency actions, section 307(b)(1) of the CAA
    Amendments of 1977 vested exclusive jurisdiction in the
    Court of Appeals for the District of Columbia Circuit to
    review all final EPA actions of nationwide consequence,
    whether such action is pursuant to specifically enumerated
    provisions of the CAA, or pursuant to “any other nationally
    applicable regulations promulgated, or final action taken, by
    the Administrator under [the Act].” Harrison v. PPG Indus.,
    Inc., 
    446 U.S. 578
    , 590 (1980) (quoting 
    42 U.S.C. § 7607
    (b)(1) and citing H.R. 6161, 95th Cong., 1st Sess.
    (1977)) (alteration in original). As we stated long ago, “[o]ur
    jurisdiction extends to ‘any . . . nationally applicable . . . final
    action taken by’ the EPA ‘Administrator.’” Appalachian
    Power Co., 
    208 F.3d 1015
    , 1020 n.10 (D.C. Cir. 2000)
    (quoting 
    42 U.S.C. § 7607
    (b)(1)) (emphasis added)
    (alterations in original); see also Cal. Cmtys. Against Toxics v.
    EPA, 
    934 F.3d 627
    , 634 (D.C. Cir. 2019) (stating section
    307(b)(1) “confers jurisdiction . . . in this court for, inter alia,
    final action of the Administrator that is ‘nationally
    applicable.’” (quoting 
    42 U.S.C. § 7607
    (b)(1))); Alon Ref.
    Krotz Springs, Inc. v. EPA, 
    936 F.3d 628
    , 642 (D.C. Cir.
    2019). In contrast, the CAA Amendments confined the
    jurisdiction of the regional courts of appeals to review of local
    or regional actions, whether such action is pursuant to
    specifically enumerated provisions of the CAA, or pursuant to
    “any other final action of the Administrator under [the CAA]
    which is locally or regionally applicable.” 
    42 U.S.C. § 7607
    (b)(1)); see also H.R. Rep. No. 95–294, at 323-24
    (1977).
    There is no question here that the SILs Guidance is
    “nationally applicable,” 
    id.
     § 7607(b)(1), as the Guidance was
    2
    distributed for use nationwide, and it states “EPA believes
    that the application of these SILs in the manner described
    below would be sufficient in most situations for a permitting
    authority to conclude that a proposed source will not cause or
    contribute to a violation of . . . PSD increments,” SILs
    Guidance at 3 (emphasis added). Furthermore, even though
    its use is optional, the SILs Guidance was expressly
    developed “to promote national consistency.” Id. at 13; see
    also id. at 15 (“Having a national SIL value promotes
    consistency in implementation and prevents possible
    confusion or arbitrary choices that may arise with highly
    localized SIL values . . . .”).
    The Sierra Club contends that the SILs Guidance
    violates the CAA because it “allow[s] construction of a
    proposed source if the source shows its individual air
    pollution impact is less than a SIL, without looking at whether
    a NAAQS or increment violation will actually occur or
    worsen.” Pet’r’s Opening Br. at 20. We cannot reach that
    argument today, because the SILs Guidance presents a
    curious form of agency action – nationally applicable
    guidance that is not final agency action at the time of
    publication but that may be relied upon later to justify a
    permitting decision, which is final agency action. But when
    that future permitting decision is made, the question naturally
    will arise – which court has jurisdiction to review it? The
    answer of course depends upon the precise circumstances of
    the permit and the challenge, but I write separately to point
    out that if such review involves resolving a substantive
    challenge to the validity of the SILs Guidance similar to the
    one Sierra Club presses here, then review must occur in this
    Court.
    The EPA is certainly free to make nationally
    applicable policy, such as the SILs Guidance, via adjudication
    3
    of individual permits rather than in one fell swoop via a
    rulemaking proceeding. While agencies usually promulgate
    policies through binding guidance or regulations, it is long
    settled that an agency may also choose to enact interpretations
    of law or make administrative policy through adjudication.
    See SEC v. Chenery Corp. (Chenery II), 
    332 U.S. 194
    , 201-03
    (1947); see also Hoopa Valley Tribe v. FERC, 
    629 F.3d 209
    ,
    212 (D.C. Cir. 2010) (upholding agency policy adopted in an
    adjudication); NetworkIP, LLC v. FCC, 
    548 F.3d 116
    , 123
    (D.C. Cir. 2008) (stating an agency may make “policy choices
    through adjudication” and give the decision retroactive
    effect). “Most norms that emerge from a rulemaking are
    equally capable of emerging (legitimately) from an
    adjudication, and accordingly agencies have very broad
    discretion whether to proceed by way of adjudication or
    rulemaking.” Qwest Servs. Corp. v. FCC, 
    509 F.3d 531
    , 536
    (D.C. Cir. 2007) (internal quotation marks and citations
    omitted).
    Although administrative law in the adjudicative context
    softens the formalism of strict stare decisis, an agency’s
    adjudicative body engaged in policymaking must still adhere
    to its precedent in deciding cases. See Hatch v. FERC, 
    654 F.2d 825
    , 834-35 (D.C. Cir. 1981). Presumptively bound by
    precedent, an agency may, within the realm of its statutory
    authority, change the established law and apply newly created
    rules “in the course of an adjudication, so long as the agency
    acts pursuant to delegated authority, adopts a permissible
    construction of the statute, and adopts a rule that is not
    arbitrary and capricious.” Consolidated Edison Co. of New
    York, Inc. v. FERC, 
    315 F.3d 316
    , 323 (2003); see Hatch, 
    654 F.2d at 835-37
    ; see also NAACP v. FCC, 
    682 F.2d 993
    , 998
    (D.C. Cir. 1982). While eschewing a doctrine of binding
    precedent, administrative law retains a balanced requirement
    of consistency dictating that, in general, like circumstances
    4
    should be treated alike. See NLRB v. Wyman-Gordon Co.,
    
    394 U.S. 759
    , 770-71 (Black, J., concurring) (“If the agency
    decision reached under the adjudicatory power becomes a
    precedent, it guides future conduct in much the same way as
    though it were a new rule promulgated under the rule-making
    power.”). Thus, an agency may not “depart from a prior
    policy sub silentio or simply disregard rules that are still on
    the books,” but it may change policy if such change is
    permitted by statute and the agency articulates “good reasons”
    for doing so. FCC. v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 515 (2009).
    The Environmental Appeals Board (“EAB”) is the
    agency body that could establish EPA policy with respect to
    the SILs Guidance. Established by regulation in 1992, the
    EAB creates a body of precedent upon which it, hearing
    officers, EPA, and the regulated community rely. See 
    78 Fed. Reg. 5281
    , 5284 (Jan. 25, 2013) (“Practitioners before the
    [EAB] in permit appeals currently are guided by Board
    precedent, standing orders of the Board, and the Board’s
    Practice Manual.”); see also Stanley Abramson, et. al., 1 L. OF
    ENVTL. PROT. § 9:106 (2019). Pursuant to that mission, the
    EAB is tasked with, inter alia, discretionary review of
    individual PSD permitting decisions.          See 
    40 C.F.R. § 124.19
    (a). In the over 40 states that implement the PSD
    program in accordance with their approved SIPs, applicable
    EPA regulations require notice, a comment period, and a
    public hearing on applications for new sources of air
    pollution. 
    Id.
     §§ 124.10-.12. Upon final approval of an
    application by a state permitting authority, participants in the
    comment process may petition the EPA Administrator for
    administrative review through the EAB. Id. § 124.19(a).
    EAB decisions are final agency actions published in the
    Federal Register, id. § 124.19(l); therefore review of EAB
    decisions on “locally or regionally applicable” permit appeals
    5
    are heard by the appropriate regional court of appeals, 
    42 U.S.C. § 7607
    (b)(1), while review of “nationally applicable”
    permit appeals must be heard in this Court, 
    id.
     Because the
    regulations allow a petitioner to challenge “any condition of
    any [specified] permit decision,” 
    40 CFR § 124.19
    (a), which
    the EAB has construed “to include . . . the permit decision in
    its entirety, whether based on alleged substantive or
    procedural defects,” 78 Fed. Reg. at 5284, the EAB could
    potentially rule upon a substantive challenge to the SILs
    Guidance similar to the one asserted here by the Sierra Club.
    Should an EAB decision pass on such a substantive
    challenge to the SILs Guidance, review must be held in this
    Court, since the SILs Guidance is by its nature nationally
    applicable, EAB decisions are precedent for future parties and
    regulated entities, and the EAB decision would be, at a
    minimum, persuasive authority for every future permit
    issuance in the nation. See Appalachian Power, 
    208 F.3d at
    1021 n.10 (“Our jurisdiction extends to ‘any . . . nationally
    applicable . . . final action taken by’ the EPA.” (quoting 
    42 U.S.C. § 7607
    (b)(1)) (alterations in original). As the Supreme
    Court made clear in Harrison, Congress intended for
    nationally applicable final agency action under the CAA to be
    heard here, 
    446 U.S. at 590
    , and it would not make sense to
    have various state courts or regional courts of appeals issue
    potentially inconsistent rulings on substantive challenges to
    the national SILs Guidance or review of permitting decisions
    based upon the Guidance.
    And adjudication by the EAB is not the only forum in
    which EPA might take nationally applicable final action with
    respect to the SILs Guidance.         For instance, EPA’s
    Administrator “may determine that [an] otherwise locally or
    regionally applicable action has nationwide scope or effect
    and publish his finding,” requiring review in this Court.
    6
    Sierra Club v. EPA, 
    926 F.3d 844
    , 849 (D.C. Cir. 2019)
    (citing 
    42 U.S.C. § 7607
    (b)(1)). Additionally, although the
    majority of PSD permitting decisions are made by the
    relevant state authorities, in localities without PSD programs
    in their state implementation plans, EPA itself manages the
    PSD program and issues preconstruction permits. See
    generally 
    40 C.F.R. § 52.21
    ; Puerto Rican Cement Co. v.
    EPA, 
    889 F.2d 292
    , 294 (1st Cir. 1989) (reviewing a PSD
    preconstruction permit issued by EPA directly). Whatever the
    administrative context, the pathway appears the same –
    should EPA, in the course of issuing an individual permitting
    decision, an appeal to the EAB, or through another method,
    take final agency action approving of, passing on, or
    otherwise ruling on the substance of the SILs Guidance in a
    nationally applicable manner, review should be had in this
    Court under section 307(b)(1), just as Congress commanded.
    RANDOLPH, Senior Circuit Judge, concurring: I concur in the
    majority opinion. As to Judge Wilkins’ separate concurring
    opinion, I see no reason to decide what we would decide if
    only the case before us were a different case.
