    83 Fed. Reg. 12,753
     (Mar. 23, 2018)
    ON PETITION FOR REHEARING
    Before Haynes, Graves, and Duncan, Circuit Judges.
    Stuart Kyle Duncan, Circuit Judge:
    The petition for rehearing is DENIED. We withdraw our prior
    opinion, reported at 
    960 F.3d 236
    , and substitute the following:
    We consider EPA’s administration of the Title V permitting program
    under the Clean Air Act (the “Act”), 
    42 U.S.C. § 7401
     et seq. Added to the
    Case: 18-60384      Document: 00515525547         Page: 2     Date Filed: 08/13/2020
    No. 18-60384
    Act in 1990, Title V is designed to consolidate in a single operating permit all
    substantive requirements a pollution source must comply with, including
    preconstruction permits previously issued under Title I of the Act. In this
    case, ExxonMobil sought a revised Title V permit concerning an expansion
    of a plant in Baytown, Texas. Petitioners Environmental Integrity Project and
    Sierra Club asked EPA to object on the grounds that, in their view, the
    underlying Title I preconstruction permit allowing the expansion was invalid.
    EPA rejected Petitioners’ arguments and declined to object. In so doing, EPA
    explained it has recently returned to its original view of Title V, under which
    the Title V permitting process is not the appropriate vehicle for re-examining
    the substantive validity of underlying Title I preconstruction permits.
    Petitioners ask us to review EPA’s decision. Concluding EPA’s
    interpretation of the Title V program is independently persuasive and
    therefore entitled to the mild form of deference recognized by Skidmore v.
    Swift & Co., 
    323 U.S. 134
     (1944), we deny the petition.
    I.
    A.
    The Act “establishes a comprehensive program for controlling and
    improving the nation’s air quality through state and federal regulation.”
    BCCA Appeal Grp. v. EPA, 
    355 F.3d 817
    , 821–22 (5th Cir. 2003). It does so
    through “[a]n experiment in cooperative federalism” that divides
    responsibilities between EPA and the states. Luminant Generation Co. v. EPA,
    
    675 F.3d 917
    , 921 (5th Cir. 2012) (quoting Michigan v. EPA, 
    268 F.3d 1075
    ,
    1083 (D.C. Cir. 2001)). EPA “formulat[es] national ambient air quality
    standards,” Util. Air Regulatory Grp. v. EPA, 
    573 U.S. 302
    , 308 (2014),
    whereas the states bear the “primary responsibility” for implementing those
    standards, id.; accord Michigan, 
    268 F.3d at 1083
     (EPA’s “overarching role is
    in setting standards, not in implementation”).
    This case involves permits issued under Title I’s New Source Review
    (“NSR”) program, which Congress added to the Act in 1977. See New York
    2
    Case: 18-60384      Document: 00515525547         Page: 3    Date Filed: 08/13/2020
    No. 18-60384
    v. EPA, 
    413 F.3d 3
     (D.C. Cir. 2015). The NSR program requires operators to
    obtain a preconstruction permit before building a new facility or modifying
    an old one. These permits are issued by the states, through mechanisms
    called state implementation plans (“SIPs”). Once a state has designed its
    SIP, the state must submit it to EPA. See generally 
    42 U.S.C. § 7410
    . EPA
    must review the SIP to ensure its compliance with Title I and provide notice
    and an opportunity to comment regarding the SIP. 
    Id.
     § 7410(a)(2). Only if
    the SIP complies with the Act must EPA approve it. Id. § 7410(k)(3)). States
    periodically revise their SIPs to keep up with EPA’s new substantive
    regulations. As with their original SIPs, states have to submit revisions to
    EPA, which again subjects them to notice and comment and then approves
    them unless they “interfere” with attainment of Title I standards. Id.
    § 7410(l).
    Title I contains provisions that apply to all SIPs. Under these
    provisions, before breaking ground on a new facility, an operator applies to
    the state for a new-source permit. The state must provide notice and an
    opportunity to comment before it approves individual preconstruction
    permits. See 
    40 C.F.R. § 51.161
    (a). The substantive requirements for
    preconstruction permits differ markedly depending on whether the new
    source is deemed “major” or “minor.” A source is major if it has “the
    potential to emit 100 tons per year of any air pollutant.” Util. Air Regulatory
    Grp., 573 U.S. at 310 (citing 
    42 U.S.C. §§ 7661
    (2)(B), 7602(j) (cleaned up)).
    The Act specifies “in considerable detail” the requirements states must
    meet to grant preconstruction permits to major sources. Luminant Generation
    Co., 675 F.3d at 922 (citing 
    42 U.S.C. §§ 7470
    –7503). In contrast, the Act’s
    requirements for minor new-source review are “sparse,” allowing for
    “wide[]” variation “from State to State.” 
    Id.
     (citing inter alia 
    40 C.F.R. §§ 51.160
    –64).
    Ordinarily, states must evaluate and permit every new source and
    every new expansion of an existing source. But in 2002, EPA promulgated a
    3
    Case: 18-60384         Document: 00515525547               Page: 4       Date Filed: 08/13/2020
    No. 18-60384
    rule that allows existing sources to expand without undergoing new-source
    review. New York, 413 F.3d at 36. Under the rule, an operator can obtain a
    ten-year Plantwide Applicability Limitation (“PAL”) permit. Id. (citation
    omitted). The whole facility can avoid major new-source review for
    alterations if, as altered, the whole facility’s emissions do not exceed levels
    specified in the PAL permit. Id. Here, again, states’ PAL programs must be
    approved by EPA, following notice and comment. See generally 
    42 U.S.C. § 7410
    .
    In 1990, Congress added Title V to the Act. Title V’s purpose is to
    provide each source a single permit that contains and consolidates all the
    information it needs to comply with the Act. 1 Accordingly, “Title V does not
    generally impose new substantive air quality control requirements.” Sierra
    Club v. Johnson, 
    541 F.3d 1257
    , 1260 (11th Cir. 2008) (citations omitted;
    cleaned up). Instead, it provides for individual operating permits that
    “contain monitoring, record keeping, reporting, and other conditions” in
    one place. 
    Id.
     (citations omitted). “In a sense,” then, a Title V permit “is a
    source-specific bible for Clean Air Act compliance.” Virginia v. Browner, 80
    1
    See, e.g., U.S. Sugar Corp. v. EPA, 
    830 F.3d 579
    , 597 (D.C. Cir. 2016) (“Title V
    does no more than consolidate existing . . . requirements into a single document . . . without
    imposing any new substantive requirements.” (quoting Sierra Club v. Leavitt, 
    368 F.3d 1300
    , 1302 (11th Cir. 2004)) (cleaned up)); 
    id.
     (Title V’s legislative history “indicates that
    permits’ purpose is “so that the public might better determine the requirements to which
    the source is subject, and whether the source is meeting those requirements” (citation
    omitted; cleaned up)); Sierra Club v. Johnson, 
    541 F.3d 1257
    , 1260 (11th Cir. 2008) (“The
    intent of Title V is to consolidate into a single document (the operating permit) all of the
    clean air requirements applicable to a particular source of air pollution.” (citation
    omitted)); 
    id.
     (describing the Title V amendments as adding “clarity and transparency . . .
    to the regulatory process” and noting that “Title V does not generally impose new
    substantive air quality control requirements”(citations omitted)); Leavitt, 
    368 F.3d at 1302
    (“Title V imposes no new requirements on sources. Rather, it consolidates existing air
    pollution requirements into a single document, the Title V permit, to facilitate compliance
    monitoring.”); see also United States v. EME Homer City Generation, L.P., 
    727 F.3d 274
    , 280
    (3d Cir. 2013) (“Title V ‘does not generally impose new substantive air quality control
    requirements[]’ . . . .” (quoting Johnson, 
    541 F.3d at 1261
    )).

    Case: 18-60384          Document: 00515525547       Page: 5   Date Filed: 08/13/2020
    No. 18-
    60384 F.3d 869
    , 873 (4th Cir. 1996). Like Title I, Title V is administered mostly by
    the states. La. Dep’t of Envtl. Quality v. EPA [LDEQ], 
    730 F.3d 446
    , 447 (5th
    Cir. 2013) (citations omitted). Accordingly, as with Title I, states develop
    their own Title V permitting programs and submit them to EPA for approval.
    
    Id.
     (citing 42 U.S.C. § 7661a(d)). A Title V permit usually contains all of the
    source’s Title I preconstruction permits. Title V permits sometimes contain
    other state-approved preconstruction permits, issued pursuant to state-
    specific standards. Any such state permits must be designated as “state-
    only” or as not “federally enforceable” in the Title V operating permit. See
    
    40 C.F.R. § 70.6
    (b)(2).
    Once a state approves a Title V permit, it submits the permit to EPA
    for review. 42 U.S.C. § 7661d(a)(1). If the permit does not comply with Title
    V, EPA must object to it within forty-five days. Id. § 7661d(b)(1). If EPA does
    not object, “any person may petition” within sixty days of the end of the
    objection period for EPA to object. Id. § 7661d(b)(2). EPA then has sixty
    more days to decide whether to grant the petition. EPA must object to the
    permit “if the petitioner demonstrates to [EPA] that the permit is not in
    compliance with [Title V], including the requirements of the applicable
    implementation plan.” Id. A denial of a petition constitutes a final agency
    action subject to judicial review. Id. Title V permits must be renewed every
    five years. Id. § 7661a(b)(5). Each renewal carries with it the petition process
    described above.
    Title V requires each permit to include four kinds of contents:
    (1) “enforceable emission limitations and standards,” (2) a compliance
    schedule, (3) a monitoring and recordkeeping requirement, and (4) “such
    other conditions as are necessary to assure compliance with applicable
    requirements of this chapter, including the requirements of the applicable
    implementation plan.” Id. § 7661c(a). 2 The Act does not define “applicable
    2
    The provision reads in whole:
    5
    Case: 18-60384       Document: 00515525547              Page: 6      Date Filed: 08/13/2020
    No. 18-60384
    requirements,” but EPA has defined the term in implementing regulations to
    mean
    all of the following as they apply to emissions units in a [Title
    V] source . . . :
    (1) Any standard or other requirement provided for in the
    applicable implementation plan approved or promulgated by
    EPA through rulemaking under title I of the Act that
    implements the relevant requirements of the Act, including
    any revisions to that plan . . . ; [and]
    (2) Any term or condition of any preconstruction permits
    issued pursuant to regulations approved or promulgated
    through rulemaking under title I . . . .
    
    40 C.F.R. § 70.2
    .
    EPA has twice changed its interpretation of Title V and § 70.2.
    Immediately following Title V’s passage, EPA expressed the view that a Title
    V permit should incorporate the source’s Title I preconstruction permit
    limits “without further review.” In the Matter of PacifiCorp Energy, Hunter
    Power Plant, Order on Petition No. VIII-2016-4 [Hunter Order], at 11 (Oct. 16,
    2017) (quoting Proposed Operating Permit Program, 
    56 Fed. Reg. 21,712
    ,
    21,738–39 (May 10, 1991)). Accordingly, a source’s Title I permit
    “define[d]” the “applicable requirements” that must appear in a Title V
    operating permit pursuant to § 7661c(a) and § 70.2. Id. at 10 (quoting
    Operating Permit Program, 
    57 Fed. Reg. 32,250
    , 32,259 (July 21, 1992)). This
    reflected EPA’s view that “the intent of title V is not to second-guess the
    Each permit issued under this subchapter shall include enforceable
    emission limitations and standards, a schedule of compliance, a
    requirement that the permittee submit to the permitting authority, no less
    often than every 6 months, the results of any required monitoring, and
    such other conditions as are necessary to assure compliance with
    applicable requirements of this chapter, including the requirements of the
    applicable implementation plan.
    
    Id.

    Case: 18-60384      Document: 00515525547            Page: 7   Date Filed: 08/13/2020
    No. 18-60384
    results of any State’s NSR program.” 
    Id.
     (quoting Proposed Operating Permit
    Program, 56 Fed. Reg. at 21,739) (cleaned up); see also Operating Permit
    Program, 57 Fed. Reg. at 32,259 (“As stated in the May 10, 1991 proposal,”
    the intent of certain changes to proposed program “is not to second-guess
    the results of any State NSR determination.”).
    A few years later, EPA began drifting from this view, interpreting
    § 70.2(1) more broadly to allow the agency to “examine the propriety of prior
    construction permitting decisions.” Hunter Order at 11. In 1997, for instance,
    the agency construed § 70.2(1) to require that a source seeking a Title V
    permit must have received the correct kind of new-source permit. Id. at 11–
    12 (citing In the Matter of Shintech, Inc., Order on Petition, Permit Nos. 2466-
    VO, 2467-VO, 2468-VO (Sept. 10, 1997)). And in 1999, an EPA official issued
    a letter to state permitting authorities asserting that the term “applicable
    requirements”     includes    the     requirement    to   obtain   the   correct
    preconstruction permits, which must comply with “the Act, EPA
    regulations, and SIP’s [sic].” Id. at 12 (citation omitted). On this view, EPA
    may use Title V review to object to an “improper preconstruction
    determination.” Id. (citation omitted; cleaned up).
    In more recent matters, EPA has gone as far as reviewing state
    agencies’ permitting decisions for reasonableness and arbitrariness. Id. at 12–
    13 (citing In the Matter of American Electric Power, John W. Turk Plant, Order
    on Petition No. VI-2008-01 (Dec. 15, 2009); In the Matter of Cash Creek
    Generation, Order on Petition Nos. IV-2008-1 & IV-2008-2 (Dec. 15, 2009); In
    the Matter of Cash Creek Generation, Order on Petition No. IV-2010-4 (June 22,
    2012)). And at least twice, EPA has considered whether sources permitted as
    minor sources should have been subject to major new-source review. Id. at 13
    (citing In the Matter of CEMEX, Inc.—Lyons Cement Plant, Order on Petition
    VIII-2008-01 (April 20, 2009); In the Matter of Wisc. Power and Light—
    Columbia Generating Stations, Order on Petition No. V-2008-1 (Oct. 8, 2009)).

    No. 18-60384
    In 2017, however, EPA returned to its original view of Title V. In
    denying a petition to object to a Title V permit for a Utah power plant, EPA
    announced that it now construes § 70.2 such that the requirements described
    by subsection (1) are merely those contained in the facility’s existing Title I
    permit. Hunter Order at 10. Accordingly, in Title V review, neither EPA nor
    state permitting authorities must determine whether the source received the
    right kind of preconstruction permit. It is enough that the Title V permit
    reflects the result of the state preconstruction permitting decision. The result
    of that process, whether it be a major or minor permit or no permit at all,
    “define[s]” the source’s requirements “for purposes of title V permitting.”
    Id. (quoting 
    57 Fed. Reg. 32,250
    , 32,259 (July 21, 1992)). 3
    B.
    In 2005, the Texas Commission on Environmental Quality
    (“TCEQ”) issued a PAL permit for ExxonMobil’s Baytown Olefins Plant
    (the “Plant”). This particular permit is called PAL6. It includes the Plant’s
    plantwide applicability limits, such that any expansion within those limits will
    not trigger major new-source review. PAL6 was incorporated into the Plant’s
    Title V permit in 2006. See In the Matter of ExxonMobil Corp., Baytown Olefins
    Plant, Order on Petition No. VI-2016-12, at 7 (Mar. 1, 2018). 4
    In 2012, ExxonMobil applied for a Title I preconstruction permit to
    build a new ethylene production facility (the “Facility”) at the Plant. PAL6
    allowed the Facility to circumvent “major” new-source permitting
    3
    The Tenth Circuit recently decided an appeal directly from the Hunter Order. See
    Sierra Club v. EPA, 
    964 F.3d 882
     (10th Cir. 2020). It held the Hunter Order contradicts
    § 70.2’s definition of “applicable requirements,” which, according to the court,
    “unambigiously refers to all requirements in a [SIP], . . . including . . . requirements for
    major NSR.” Id. at 891. The Hunter Order’s reasoning is discussed at greater length below.
    4
    EPA has approved Texas’s Title I SIP, 
    40 C.F.R. § 52.2270
    , its PAL program,
    Final Rule, Revisions to the NSR State Implementation Plan, Texas, 
    77 Fed. Reg. 65,119
     (Oct.
    25, 2012), and its Title V permitting program, Clean Air Act Full Approval of Operating
    Permits Program; State of Texas, 
    66 Fed. Reg. 63,318

    requirements, and so ExxonMobil applied for and ultimately received a
    “minor” new-source permit. Environmental Integrity Project, Sierra Club,
    and Air Alliance Houston 5 filed comments and requested a contested case
    hearing before the Texas State Office of Administrative Hearings. They
    challenged the Facility’s preconstruction permit, arguing the Facility should
    have required a major new-source permit. This is because, in their view,
    PAL6 contravenes federal PAL rules, such that it cannot validly shield the
    Facility from major new-source permitting. After a hearing, two
    administrative law judges from Texas’s Office of Administrative Hearings
    ruled against the groups. TCEQ then issued a minor new-source permit for
    the Facility.
    ExxonMobil applied to TCEQ to modify the Plant’s Title V permit to
    incorporate the minor new-source permit. Petitioners again filed comments,
    reiterating their argument that PAL6 was invalid. Despite their comments,
    TCEQ submitted the revised Title V permit to EPA for review. EPA did not
    object. Accordingly, TCEQ issued the permit. Petitioners could have, see 42
    U.S.C. § 7661a(b)(6), but did not appeal TCEQ’s decision to a Texas state
    court. Instead, in August 2016, the groups petitioned EPA to object to the
    Title V permit.
    EPA denied the petition. Relying on the Hunter Order, the agency
    explained that
    [w]here the EPA has approved a state’s Title I permitting
    program, duly issued preconstruction permits will establish the
    ‘applicable requirements,’ and the terms and conditions of
    those permits should be incorporated into a source’s Title V
    permit without further review.
    5
    Air Alliance Houston is not a party to this appeal.

    No. 18-60384
    Because “any such challenges should be raised through the appropriate Title
    I permitting procedures or enforcement authorities,” EPA would not object
    to the Title V permit.
    Petitioners timely sought our review.
    II.
    We will overturn EPA’s denial of the petition only if it was “arbitrary,
    capricious, an abuse of discretion, or otherwise not in accordance with law.”
    
    5 U.S.C. § 706
    (2)(A); accord Alaska Dep’t of Envtl. Conservation v. EPA, 
    540 U.S. 461
    , 496–97 (2004). “The scope of review under the ‘arbitrary and
    capricious’ standard is narrow.” Motor Vehicle Mfrs. Ass’n v. State Farm Mut.
    Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983). An agency action will be overturned
    only if it is contrary to statute or “if the agency has relied on factors which
    Congress has not intended it to consider, entirely failed to consider an
    important aspect of the problem, offered an explanation for its decision that
    runs counter to the evidence before the agency, or is so implausible that it
    could not be ascribed to a difference in view or the product of agency
    expertise.” 
    Id.
    Petitioners must “demonstrate[] . . . that the permit is not in
    compliance with the requirements of” Title V. 42 U.S.C. § 7661d(b)(2).
    Only that showing triggers EPA’s duty to object to the permit. LDEQ, 730
    F.3d at 447.
    III.
    This dispute centers on an agency’s interpretation of a statutory
    scheme that Congress has charged it with administering. In such a dispute,
    we ordinarily decide first whether and to what degree to defer to the agency’s
    interpretation. See, e.g., Texas v. EPA, 
    829 F.3d 405
    , 425 (5th Cir. 2016)
    (determining what level of deference to accord to “EPA’s interpretation of
    the Clean Air Act”). EPA claims the Hunter Order, which undergirds its
    action here, is entitled to Chevron deference. See generally Chevron, U.S.A.,

    Inc. v. Nat. Res. Def. Council, Inc., 
    467 U.S. 837
     (1984). Under Chevron, we
    defer to an agency’s interpretation when it reasonably resolves a genuine
    statutory ambiguity. United States v. Mead Corp., 
    533 U.S. 218
    , 229 (2001)
    (citing Chevron, 
    467 U.S. at
    842–45). EPA argues that the term “applicable
    requirements” in § 7661c(a) 6 is ambiguous because it compels neither
    Petitioners’ construction (that “applicable requirements” includes all the
    Act’s requirements, regardless of the contents of any preconstruction
    permit) nor EPA’s construction (that Title V does not require EPA to revisit
    preconstruction permitting decisions). EPA’s resolution of this ambiguity is
    reasonable, the agency claims, because it is “better as a matter of policy and
    better comports with the statutory structure and the principal purpose of the
    Title V program.” In turn, Petitioners respond that there is no ambiguity for
    EPA to resolve. They argue that the term “applicable requirement” is not
    ambiguous but instead is simply “broad and sweeping,” encompassing all the
    Act’s requirements as applied to a particular source, not just the
    requirements that happen to be contained in a Title I new-source permit.
    We need not decide whether the Hunter Order is entitled to Chevron
    deference because, independent of Chevron, we find its reasoning persuasive
    as a construction of the relevant provisions of Title V. We therefore accord
    the Hunter Order the deference “its persuasiveness warrants.” Union
    6
    Although EPA’s brief claims in passing that the agency “reasonably interpreted
    the statute and regulation,” the agency develops no argument as to the latter, relying only
    on Chevron deference. We note that the Hunter Order itself and EPA’s order in this matter
    both claim to interpret not § 7661c(a) but instead § 70.2. And in defending the Hunter
    Order in the Tenth Circuit, EPA invoked not only Chevron but Auer deference, under
    which courts “defer[] to agencies’ reasonable readings of genuinely ambiguous
    regulations.” Kisor v. Wilkie, 
    139 S. Ct. 2400
    , 2408 (2019) (citing Auer v. Robbins, 
    519 U.S. 452
     (1997), and Bowles v. Seminole Rock & Sand Co., 
    325 U.S. 410
     (1945)) (emphasis added);
    see Resp’t EPA’s Br. 42–44, Sierra Club v. EPA, No. 18-9507 (10th Cir. Nov. 7, 2019).
    Accordingly, the Tenth Circuit’s opinion in Sierra Club addressed the Hunter Order’s
    compliance with the definition of “applicable requirements” in § 70.2. 964 F.3d at 891.
    EPA does not invoke Auer here, and we express no view on whether Auer deference applies
    to the Hunter Order.

    deference that accords “weight” to an agency’s judgment depending on “the
    thoroughness evident in [the agency’s] consideration, the validity of its
    reasoning, its consistency with earlier and later pronouncements, and all
    those factors which give it power to persuade, if lacking power to control.”

    assuming arguendo that only Skidmore deference applies, under that standard
    we find persuasive EPA’s position that Title V does not require revisiting the
    validity of underlying Title I preconstruction permits as part of the Title V
    permitting process. 7

    Applying Skidmore, we ask whether EPA’s interpretation of Title V in
    the Hunter Order is persuasive. Specifically, we inquire into the

    The Hunter Order is framed largely as an interpretation of 
    40 C.F.R. § 70.2
    ,
    which in turn implements § 7661c(a). See Hunter Order at 9–10 (describing definitions of
    “applicable requirements” in §§ 70.2(1) and (2)). Nonetheless, we will analyze the Hunter
    Order as a construction of Title V and the Act as a whole. This accords with EPA’s
    treatment of the Hunter Order in this litigation, see supra n.6.

    Case: 18-60384      Document: 00515525547         Page: 13     Date Filed: 08/13/2020

    persuasiveness of EPA’s current view that the Title V permitting process
    does not require substantive reevaluation of the underlying Title I
    preconstruction permits applicable to a pollution source. As we read it, the
    Hunter Order defends the agency’s interpretation based principally on Title
    V’s text, Title V’s structure and purpose, and the structure of the Act as a
    whole. Having examined these reasons and found them persuasive, we
    conclude that EPA’s current approach to Title V merits Skidmore deference.
    A.
    We first consider EPA’s treatment of Title V’s text. The Hunter
    Order argues that Petitioners’ argument is fatally undermined principally not
    by what Title V includes but by what it omits: an explicit requirement that
    EPA review the “substantive adequacy” of underlying preconstruction
    permits during the Title V process. Hunter Order at 14 (citation omitted).
    The Order reasons that Title V contains no requirement that its
    “consolidation process . . . involve a review of the substantive adequacy” of
    preconstruction requirements, an undertaking that “would entail much more
    than taking steps to consolidate existing air pollution requirements.” Id.
    (quoting U.S. Sugar Corp., 830 F.3d at 597) (cleaned up). Nowhere, avers the
    agency, does Title V permitting require the state permitting authority or EPA
    to double-check whether preconstruction permits “properly derived” from
    the preconstruction rules. Nor does Title V require these requirements to
    “be re-checked every time the [Title V] permit is renewed.” Id.
    We find persuasive EPA’s position that Title V lacks a specific textual
    mandate requiring the agency to revisit the Title I adequacy of
    preconstruction permits. Our own review of Title V confirms that it contains
    no such explicit requirement, nor any language guiding the agency on how to
    perform a review of that nature. “The principle that a matter not covered is
    not covered is so obvious that it seems absurd to recite it.” Yates v. Collier,
    
    868 F.3d 354
    , 369 (5th Cir. 2017) (citation omitted). A number of cases have
    identified the casus omissus pro omisso habendus est canon, under which a
    13
    Case: 18-60384      Document: 00515525547          Page: 14     Date Filed: 08/13/2020
    No. 18-60384
    statute should not be read to include matter it does not include. See, e.g.,
    Lamie v. U.S. Tr., 
    540 U.S. 526
    , 538 (2004) (rejecting construction that
    “would have us read an absent word into the statute” because it “would
    result not in a construction of the statute, but, in effect, an enlargement of it
    by the court” (citing Iselin v. United States, 
    270 U.S. 245
    , 251 (1926))
    (cleaned up)). Here, Title V does not tell EPA to reconsider new-source
    review in the course of Title V permitting. We reject Petitioners’ position
    because “[t]here is a basic difference between filling a gap left by Congress’
    silence and rewriting rules that Congress has affirmatively and specifically
    enacted.” In re Miller, 
    570 F.3d 633
    , 638–39 (5th Cir. 2009) (quoting Lamie,
    
    540 U.S. at 538
    ) (cleaned up).
    EPA contrasts Title V’s silence on this front with more stringent
    oversight authority provided in Title I, arguing that this “supports reading
    the title V provision to supply a more limited oversight role for the EPA with
    regard to state implementation of preconstruction permitting programs.”
    Hunter Order at 14. The agency explains that Title I is better geared for “in-
    depth oversight of case-specific” state permitting decisions “such as through
    the state appeal process or an order or action under section[] 113 or section
    167.” 
    Id.
     And, the agency urges, the absence of such schemes in Title V
    shows Congress did not intend to recapitulate the Title I process in Title V.
    See, e.g., 
    id.
     at 13 n.26 (explaining that “an interpretation of title V that
    excludes revisiting preconstruction decisions does not fundamentally alter or
    limit the EPA’s authority under title I of the Act”). We find this reasoning
    persuasive. Cf. Advocate Health Care Network v. Stapleton, 
    137 S. Ct. 1652
    ,
    1658–59 (2017) (Congress’s “drafting decision” not to include statutory
    language from a comparable statute “indicates that Congress did not in fact
    want” to do so (citing Lozano v. Montoya Alvarez, 
    134 S. Ct. 1224
    , 1235
    (2014))).
    Petitioners’ disagreement with the agency’s view boils down to their
    argument that the term “applicable requirements” in § 7661c(a) requires
    14
    Case: 18-60384      Document: 00515525547          Page: 15     Date Filed: 08/13/2020
    No. 18-60384
    EPA to review preconstruction permitting decisions. According to
    Petitioners, that term encompasses all the Act’s requirements as applied to a
    particular source, and not simply the requirements that happen to be
    contained in a Title I new-source permit. Contrary to EPA’s view, Petitioners
    argue the term “applicable requirements” is not ambiguous but is simply
    “broad and sweeping.” See Consumer Elecs. Ass’n v. FCC, 
    347 F.3d 291
    , 298
    (D.C. Cir. 2003) (“[T]he Supreme Court has consistently instructed that
    statutes written in broad, sweeping language should be given broad, sweeping
    application.” (citing New York v. FERC, 
    535 U.S. 1
    , 22 (2002))). The agency
    counters that Title V’s requirement that a permit “assure compliance with
    applicable requirements” is “general” and “broad” and so does not “clearly
    or specifically” require revisiting preconstruction permitting decisions.
    Hunter Order at 15. The general term, says EPA, does not send a “clear
    indication” that Congress intended Title V to “alter the [agency’s] balance
    of oversight” over state permitting processes. In other words, the agency
    advances the familiar argument that Congress does not “hide elephants in
    mouseholes” by “alter[ing] the fundamental details of a regulatory scheme
    in vague terms or ancillary provisions.” 
    Id.
     (quoting Whitman v. Am. Trucking
    Ass’ns, 
    531 U.S. 457
    , 468 (2001)).
    We conclude EPA has the better reading of § 7661c(a). While
    “applicable requirements” may be a “broad and sweeping” phrase in the
    abstract, its context here narrows its scope. The provision reads in whole:
    Each permit issued under this subchapter shall include
    enforceable emission limitations and standards, a schedule of
    compliance, a requirement that the permittee submit to the
    permitting authority, no less often than every 6 months, the
    results of any required monitoring, and such other conditions as
    are necessary to assure compliance with applicable requirements of
    this chapter, including the requirements of the applicable
    implementation plan.
    15
    Case: 18-60384      Document: 00515525547         Page: 16     Date Filed: 08/13/2020
    No. 18-60384
    42 U.S.C. § 7661c(a) (emphasis added). Read in context, the “applicable
    requirements” clause is residual to the three listed contents: “enforceable
    emission limitations and standards,” a compliance schedule, and a periodic
    monitoring report. Residual clauses are often phrased broadly; wrenched out
    of context, they might appear to encompass far more than the preceding
    terms. That is why courts construe residual terms in light of those preceding
    terms. See, e.g., United States v. Buluc, 
    930 F.3d 383
    , 388–89 (5th Cir. 2019)
    (discussing eiusdem generis canon under which “when a general term follows
    a specific one, the general terms should be understood as a reference to
    subjects akin to the one with the specific enumeration” (quoting Ali v. Fed.
    Bureau of Prisons, 
    552 U.S. 214
    , 223 (2008)) (cleaned up)). Here, Petitioners
    read the residual clause—“other conditions as are necessary to assure
    compliance with applicable requirements”—to leap far beyond the
    enumerated contents. They would effectively rewrite the clause to read: “a
    de novo reconsideration of the source’s preconstruction permitting.” Surely,
    Congress would not have hidden that regulatory elephant in this residual
    mousehole.
    B.
    We next consider EPA’s contention that its revised interpretation of
    Title V permitting “is better aligned with the structure and purpose of [T]itle
    V itself.” Id. at 14. The Hunter Order notes that Title V was not intended to
    “add new substantive requirements” to the Act. Id. (citations omitted).
    Instead, Title V’s goal was to “streamline.” Id. at 16 (quoting 42 U.S.C.
    § 7661a(b)(6)). EPA expressed this view before enacting 40 C.F.R. part 70,
    observing that “the intent of [T]itle V is not to second-guess the results of
    any State’s NSR program.” Id. at 11; see also Proposed Operating Permit
    Program, 56 Fed. Reg. at 21,738–39 (May 10, 1991); accord Operating Permit
    Program, 57 Fed. Reg. at 32,259 (“As stated in the May 10, 1991 proposal,”
    the intent of certain changes to proposed program “is not to second-guess
    the results of any State NSR determination.”). EPA proffers this statement
    16
    Case: 18-60384       Document: 00515525547            Page: 17      Date Filed: 08/13/2020
    No. 18-60384
    as “the best indication” of the agency’s intention “when it issued” part 70.
    Hunter Order at 13. According to EPA, “[m]uch as an agency’s
    contemporaneous interpretation of a statute through a regulation is given
    great weight[,] an agency’s contemporaneous interpretation of its own
    regulations in the preamble for those regulations should carry similar
    weight.” Id. at 14. 8
    We find persuasive EPA’s view that, because Title V was not intended
    to “add new substantive requirements” to the Act, it should not be
    interpreted as Petitioners urge. Id. at 14 (citations omitted). By all accounts,
    Title V’s purpose was to simplify and streamline sources’ compliance with
    the Act’s substantive requirements. Rather than subject sources to new
    substantive requirements—or new methods of reviewing old requirements—
    “[t]he intent of Title V [was] to consolidate into a single document (the
    operating permit) all of the clean air requirements applicable to a particular
    source of air pollution.” Johnson, 
    541 F.3d at 1260
     (citation omitted); see also,
    e.g., U.S. Sugar Corp., 830 F.3d at 597 (“Title V does no more than
    consolidate existing . . . requirements into a single document . . . without
    imposing any new substantive requirements.” (citation omitted; cleaned
    up)); Leavitt, 
    368 F.3d at 1302
     (“Title V imposes no new requirements on
    sources. Rather, it consolidates existing air pollution requirements into a
    single document, the Title V permit, to facilitate compliance monitoring.”).
    The Title V permitting process was meant to add “clarity and
    transparency . . . to the regulatory process to help citizens, regulators, and
    polluters themselves understand which clean air requirements apply to a
    particular source of air pollution.” Johnson, 
    541 F.3d at 1260
    . This goal, as
    EPA argues, is at cross-purposes with using the Title V process to reevaluate
    preconstruction permits.
    8
    But see Sierra Club, 964 F.3d at 893–95 & n.10 (holding that language from the
    preambles to the proposed and actual operating programs contradicts § 70.2’s text).
    17
    Case: 18-60384      Document: 00515525547          Page: 18     Date Filed: 08/13/2020
    No. 18-60384
    We also agree with EPA that the language in part 70’s preamble is
    probative of Title V’s purpose as a whole. See, e.g., Good Samaritan Hosp. v.
    Shalala, 
    508 U.S. 402
    , 414 (1993) (finding agency’s construction of newly
    enacted law “particular[ly] relevan[t]” (citation omitted)). This is because
    one sensibly expects EPA to have had a better grasp of Congress’s intent for
    Title V shortly after its enactment. See, e.g., Udall v. Tallman, 
    380 U.S. 1
    , 16
    (1965) (according “[p]articular[] . . . respect . . . when the administrative
    practice at stake involves a contemporaneous construction of a statute by the
    men charged with the responsibility of setting its machinery in motion; of
    making the parts work efficiently and smoothly while they are yet untried and
    new” (citation omitted; cleaned up)). Mere months after Title V’s
    enactment, EPA stated that Title V permits are to “incorporate” the
    standards contained in Title I preconstruction permits without further
    review.” Proposed Operating Permit Program, 56 Fed. Reg. at 21,738–39
    (emphasis added). If that were not enough, EPA stated flatly that “[t]he
    intent of [T]itle V is not to second-guess the results of any State NSR
    program.” Id. at 21,739.
    We recognize that EPA has reverted to its original interpretation of
    § 70.2, reflecting its changing views of Title V. We take the agency’s change
    of position into account in determining whether to defer to its position. See
    Dhuka, 716 F.3d at 154 (whether to defer under Skidmore depends in part on
    agency’s “consistency with earlier and later pronouncements”). But even
    when “the agency has embraced a variety of approaches,” we may still defer
    to its present position, “especially” when the current view “closely fits the
    design of the statute as a whole.” Shalala, 
    508 U.S. at
    417–18 (citation
    omitted; cleaned up); see also 
    id. at 417
     (“The [agency] is not estopped from
    changing a view [it] believes to have been grounded upon a mistaken legal
    interpretation.” (citation omitted)).
    Finally, we are persuaded that Petitioners’ capacious view of Title V
    review is at odds with the “abbreviated” timeline Congress gave EPA.
    18
    Case: 18-60384         Document: 00515525547             Page: 19       Date Filed: 08/13/2020
    No. 18-60384
    Hunter Order at 16. EPA has forty-five days to conduct an independent
    review of a Title V permit. 42 U.S.C. § 7661d(b). If anyone petitions EPA, it
    has sixty more days to decide whether to object to a petition. Id. We agree
    that these timelines are “inconsistent with an in-depth and searching review
    of every” permitting decision regarding a given source. Hunter Order at 16. 9
    We also observe that the fact that Title V permits must be renewed every five
    years, see 42 U.S.C. § 7661a(b)(5), tends to support the agency’s view that
    Title V was not intended to serve as a vehicle for re-examining the underlying
    substance of preconstruction permits. Subjecting a source’s preconstruction
    permit to periodic new scrutiny, without any changes to the source’s
    pollution output, would be inconsistent with Title V’s goal of giving sources
    more security in their ability to comply with the Act. See id. § 7661a(b)(6).
    C.
    Beyond the structure of Title V, EPA also persuasively grounds its
    interpretation in the structure of the Act as a whole. According to EPA, when
    Congress added preconstruction permitting requirements to Title I in 1977,
    it “understood that the adequacy of state preconstruction permitting
    decisions would be subject to review in state administrative and judicial
    forums.” Hunter Order at 13. It gave EPA oversight authority over
    preconstruction permitting only in specific ways, to do specific things. For
    example, Congress delineated the processes EPA must go through to approve
    SIPs. Id. at 14–15 (citing § 7410(a)(2)(C)). When it enacted Title V thirteen
    9
    Making a similar point, EPA points out that the Act requires states to issue Title
    V permits through
    streamlined[] and reasonable procedures for expeditiously determining when
    applications are complete, for processing such applications, for public
    notice, including offering an opportunity for public comment and a
    hearing, and for expeditious review of permit actions, including
    applications, renewals, or revisions.
    42 U.S.C. § 7661a(b)(6) (emphasis added).

    No. 18-60384
    years later, Congress granted EPA no such authority. Id. at 15. Congress gave
    no “clear indication” that it intended to “alter the balance of oversight” EPA
    has over state permitting processes. Section 7661c(a)’s requirement that a
    Title V permit “assure compliance with applicable requirements” is
    “general” and “broad” and does not “clearly or specifically” require the
    revisiting of preconstruction permitting decisions. Id. Once again, the
    “elephants in mouseholes” canon supports this reading. Id. (quoting
    Whitman, 
    531 U.S. at 468
    ).
    We find persuasive the agency’s view that the Act’s overall structure
    supports its interpretation of Title V. We have frequently noted the Act’s
    “experiment in cooperative federalism.” Luminant Generation Co., 675 F.3d
    at 921 (quoting Michigan, 
    268 F.3d at 1083
    ); see also Texas, 829 F.3d at 411
    (same). Applied to NSR, this principle of federalism means it is the states,
    not EPA, that issue preconstruction permits for new sources. See generally 
    42 U.S.C. § 7410
    . And it is the states, not EPA, that issue Title V permits. 
    Id.
    § 7661a(d); see also LDEQ, 730 F.3d at 447 (Title V is administered mostly
    by the states (citations omitted)). While EPA retains near-plenary authority
    to approve or recall SIPs it finds inconsistent with the Act, 
    42 U.S.C. § 7410
    (k), the Hunter Order is correct that the agency’s authority over
    improperly issued preconstruction permits generally stops there. See
    generally Hunter Order at 14–16 (describing EPA’s authority to review
    preconstruction permits). While § 7661c(a) requires permits to contain
    conditions necessary to “assure compliance with applicable requirements,”
    we agree with EPA that this requirement is too “general” and “broad” to
    upset the Act’s balance of power between EPA and the states. Id. We thus
    agree that when it enacted Title V, Congress gave no “clear indication” that
    it intended to “alter the balance of oversight” EPA has over state permitting
    processes. Hunter Order at 15. As discussed above, Petitioners’ contrary view
    puts too much weight on § 7661c(a)’s residual clause.

    For similar reasons, we are persuaded by the agency’s contrasting
    Title V against Title I’s more detailed procedures for “in-depth oversight of
    case-specific” permitting decisions. Id. at 14. Such permitting decisions
    follow state appeals or enforcement actions authorized by other provisions of
    the Act, including citizen suits under Title III. Id. Those mechanisms are
    better structured to provide agency and citizen oversight of preconstruction
    permitting. Id. Petitioners’ contrary view would make Title V a vehicle for
    the public to (again) challenge preconstruction permits. But Title V contains
    none of the procedures that would guide those challenges, as Titles I and III
    do. Id.
    Finally, according to the Order, EPA’s position also “respects the
    finality” of the preconstruction permitting decision. Id. at 18. The agency
    reasoned that it would be “inefficient” to allow review via the Title V
    permitting process even after the preconstruction permits had been subject
    to “public notice and comment and an opportunity for judicial review.” Id.
    at 17. And those avenues provide “more time for development and
    consideration of the potential issues.” Id. at 17–18. We are persuaded that
    EPA’s construction of Title V “respects the finality” of state
    preconstruction permitting decisions, which is consistent with the Act’s
    “cooperative federalism.” Luminant Generation Co., 675 F.3d at 921.
    Petitioners’ contrary view of Title V would allow a federal agency to upset
    states’ permitting decisions with no clear mandate from Congress to do so. 10

    We emphasize that nothing in this opinion prevents Petitioners from
    continuing to challenge the Facility’s compliance with the Act in other

    Because we hold that EPA need not reconsider the validity of Title I
    preconstruction permits under Title V, we do not reach EPA’s alternative argument that
    Petitioners have failed to demonstrate PAL6 and the Facility’s Title I permit are
    substantively invalid.

    contexts. As the agency’s order in this case explained, “a decision by the EPA
    not to object to a title V permit that includes the terms and conditions of a
    title I permit does not indicate that the EPA has concluded that those terms
    and conditions comply with the applicable SIP or the [Act].” For instance,
    the agency observed that “ExxonMobil has submitted a request to renew
    PAL6,” giving “the public the opportunity to participate in [a] future PAL
    permit proceeding, including the opportunity to comment on any relevant
    outstanding concerns with PAL6.” And, of course, Petitioners remain free
    within the Act’s bounds to enforce its substantive provisions should the
    Facility violate them. See generally 
    42 U.S.C. § 7604
     (authorizing citizen suits
    to enforce violations).
    All we address here is EPA’s view that Title V permitting is not the
    appropriate vehicle for reexamining the substantive validity of underlying
    Title I preconstruction permits. We conclude that the agency’s
    interpretation is persuasive and therefore entitled at least to Skidmore
    deference.
    The petition is DENIED.
