    Concurring opinion filed by Circuit Judge KAVANAUGH.
    GARLAND, Chief Judge: The Utility Air Regulatory Group
    and the State of Texas challenge 2009 and 2012 final rules
    issued by the Environmental Protection Agency (EPA) under the
    Clean Air Act. The rules revised the new source performance
    standards for steam generating units. Several of the petitioners’
    challenges are not properly before us because they were first
    raised in petitions for reconsideration that remain pending before
    the agency. We reject the petitioners’ remaining challenges and
    deny the petitions for review.

    I
    The Clean Air Act directs the EPA Administrator to publish
    and periodically revise a list of categories of stationary sources,
    which are large, fixed sources of air pollution. 42 U.S.C.
    § 7411(a)(3), (b)(1)(A). The Administrator must include a
    category of sources in this list “if in his judgment it causes, or
    contributes significantly to, air pollution which may reasonably
    be anticipated to endanger public health or welfare.” 
    Id. § 7411(b)(1)(A).
    Once a source category is listed, the
    Administrator must establish new source performance standards
    for that category. 
    Id. § 7411(b)(1)(B).1
    Fossil-fuel-fired steam generating units are boilers that
    produce electricity. In so doing, they emit particulate matter
    into the atmosphere. Because EPA determined that those
    emissions “may contribute significantly to air pollution which
    causes or contributes to the endangerment of public health or
    welfare,” List of Categories of Stationary Sources, 36 Fed. Reg.
    5931, 5931 (Mar. 31, 1971), it promulgated new source
    performance standards for those units. The regulations are
    divided into four subparts within 40 C.F.R. Part 60 -- Subparts
    1
    A “new source” is “any stationary source, the construction or
    modification of which is commenced after the publication of
    regulations . . . prescribing a standard of performance under this
    section which will be applicable to such source.” 42 U.S.C.
    § 7411(a)(2). A “standard of performance” is “a standard for
    emissions of air pollutants which reflects the degree of emission
    limitation achievable through the application of the best system of
    emission reduction which (taking into account the cost of achieving
    such reduction and any nonair quality health and environmental
    impact and energy requirements) the Administrator determines has
    been adequately demonstrated.” 
    Id. § 7411(a)(1).
                                      4
    D, Da, Db, and Dc -- each of which concerns a specific group of
    sources.2
    To ensure that steam generating units comply with emission
    limits, EPA requires that they measure the particulate matter in
    their emissions.      When EPA initially promulgated the
    regulations, the only way to measure such emissions was to
    perform a manual test. See Standards of Performance for New
    Stationary Sources, 36 Fed. Reg. 24,876, 24,888-90 (Dec. 23,
    1971). To provide an alternative (and less expensive) way to
    assess compliance, EPA later added opacity standards to its
    boiler rules. See Standards of Performance for New Stationary
    Sources: Additions and Miscellaneous Amendments, 39 Fed.
    Reg. 9308, 9308-09 (Mar. 8, 1974). Opacity is not a pollutant
    but rather can serve as a proxy for pollutants: It measures the
    degree to which stack emissions block the transmission of light.
    Opacity can be measured by (among other things) visual
    inspection by a trained observer or by a continuous opacity
    monitoring system (COMS). A COMS requires the installation
    of equipment in the steam generating unit’s stack. This
    2
    Subpart D covers fossil-fuel-fired electric utility steam
    generating units (EGUs) of greater than 73 megawatts (MW) heat
    input capacity, on which construction, modification, or reconstruction
    commenced after August 17, 1971 and on or before September 18,
    1978. See 40 C.F.R. § 60.40(a). Subpart Da covers EGUs of greater
    than 73 MW heat input capacity on which construction, modification,
    or reconstruction began after September 18, 1978. See 
    id. § 60.40Da(a).
    Subpart Db covers industrial-commercial-institutional
    steam generating units with a heat input capacity of greater than 29
    MW on which construction, modification, or reconstruction began
    after June 19, 1984. See 
    id. § 60.40b(a).
    And Subpart Dc covers
    industrial-commercial-institutional steam generating units with a heat
    input capacity of between 2.9 and 29 MW, on which construction,
    modification, or reconstruction began after June 9, 1989. See 
    id. § 60.40c(a).
                                   5
    equipment shines a light beam through stack gases and records
    the resulting opacity readings at fixed intervals.
    A newer form of monitoring technology is a continuous
    emissions monitoring system (CEMS). A CEMS, like a COMS,
    requires the installation of monitoring equipment in the unit’s
    stack. But a CEMS measures pollutants directly, rather than by
    measuring opacity as a proxy. Both a CEMS and a COMS
    measure only filterable particulate matter -- which is emitted
    from the stack as a solid. They do not measure condensable
    particulate matter -- which is emitted as a gas, but turns liquid
    or solid upon exiting the stack. Visual inspection, by contrast,
    can measure both. Historically, however, only filterable
    particulate matter has been subject to emission limitations.
    In 2006 and 2007, EPA gave facilities the option of
    installing particulate matter CEMS as “an alternative method to
    demonstrate continuous compliance and as an alternative to
    opacity . . . monitoring requirements.”           Standards of
    Performance [for Subparts Da, Db, and Dc Units], 71 Fed. Reg.
    9866, 9867-68 (Feb. 27, 2006); see Standards of Performance
    [for Subparts D, Da, Db, and Dc Units], 72 Fed. Reg. 32,710,
    32,719 (June 13, 2007). The agency said that, because
    particulate matter CEMS “measure the pollutant of primary
    interest they provide adequate assurance of [particulate matter]
    control device performance, and continuous opacity monitoring
    is an unnecessary burden to affected sources using” CEMS.
    Standards of Performance [for Subparts D, Da, Db, and Dc
    Units]; Reconsideration and Amendments, 72 Fed. Reg. 6320,
    6322 (proposed Feb. 9, 2007). EPA did not, however, eliminate
    the opacity standards themselves; it merely said that facilities
    using CEMS were no longer required to install and operate
    COMS. See Standards of Performance [for Subparts D, Da, Db,
    and Dc Units], 73 Fed. Reg. 33,642, 33,644 (proposed June 12,
    2008) [hereinafter 2008 Proposal].
    6
    In 2008, EPA published a notice of proposed rulemaking,
    seeking comment on the possible elimination of opacity
    standards altogether for facilities using CEMS. See 
    id. at 33,646.
    The agency said that elimination of such standards at
    those units might be appropriate, “[s]ince opacity data has been
    used as a surrogate for [particulate matter] emissions and since
    [particulate matter] CEMS give a more direct continuous
    measurement of the primary pollutant of interest causing
    opacity.” 
    Id. (footnote omitted).
    EPA noted, however, that
    opacity is useful not only as a proxy for pollutants, but also “as
    an indicator of control device operation and proper
    maintenance.” 
    Id. at 33,646
    n.1.
    The 2009 final rule exempted all units using particulate
    matter CEMS from all opacity standards and monitoring
    requirements, but conditioned the exemption on their
    compliance with an emission standard for filterable particulate
    matter of 0.03 pounds per million British thermal units
    (lb/MMBtu) or less, rather than any otherwise applicable, higher
    limits. See Standards of Performance [for Subparts D, Da, Db,
    and Dc Units], 74 Fed. Reg. 5072, 5073-74 (Jan. 28, 2009)
    [hereinafter 2009 Rule]. For Subpart D units, for example, the
    higher limit was 0.10 lb/MMBtu. See 40 C.F.R. § 60.42.3
    If a unit that was using a particulate matter CEMS did not
    comply with the lower limit, the 2009 rule required it “to either
    use a COMS or perform periodic visual inspections to comply
    with the opacity standard.” 
    Id. at 5074.
    The frequency of such
    inspections depended on the results of the most recent
    inspection. See 
    id. In addition,
    the rule required all facilities to
    3
    By the time of the 2009 Rule, Subpart Da units were already
    required to comply with the 0.03 lb/MMBtu limit, see 40 C.F.R.
    § 60.42Da (2007), as were certain, newer Subparts Db and Dc units,
    see 
    id. §§ 60.43b(h)(1),
    60.43c(e)(1) (2007).
    7
    measure and report emissions of condensable particulate matter.
    See 
    id. at 5073.
    UARG filed a petition for reconsideration of the 2009 rule.
    Among other things, it asked EPA to reconsider its decision to
    limit the exemption from the opacity standard and monitoring
    requirements to units complying with the 0.03 lb/MMBtu
    emission standard. EPA granted the petition for reconsideration.
    At the same time, it published notice of a new proposed rule. In
    most respects, the proposal tracked the 2009 final rule. It
    contained only two differences relevant here: First, EPA
    proposed a total (that is, filterable plus condensable) particulate
    matter emission limit for certain Subpart Da units on which
    construction, reconstruction, or modification commenced after
    May 3, 2011. Second, EPA proposed to add an affirmative
    defense to civil penalties for exceedances of emission limits that
    are caused by malfunctions. See Standards of Performance [for
    Subparts D, Da, Db, and Dc Units], 76 Fed. Reg. 24,976,
    25,061, 25,064, 25,071 (proposed May 3, 2011) [hereinafter
    2011 Proposal].
    Thereafter, UARG submitted a new round of comments. It
    argued that EPA should exempt all Subpart D units using CEMS
    from the opacity standard and monitoring requirements because
    CEMS are sufficiently accurate to ensure compliance with
    emission standards. The Texas Commission on Environmental
    Quality also submitted comments urging EPA to revise its rules
    to allow steam generating units to use state-law affirmative
    defenses in lieu of the federal affirmative defense the agency
    had proposed.
    On February 16, 2012, EPA issued another final rule.
    Standards of Performance [for Subparts D, Da, Db, and Dc
    Units], 77 Fed Reg. 9304 (Feb. 16, 2012) [hereinafter 2012
    Rule]. The 2012 rule did not expand the exemption from the
    8
    opacity standard or monitoring requirements. 
    Id. at 9424.
    Although it reduced the frequency of periodic visual opacity
    inspections for Subpart Da facilities not using COMS, see 
    id. at 9457,
    it did not do so for Subparts D, Db, and Dc facilities, see
    
    id. at 9448,
    9460, 9463. The 2012 rule also required certain
    Subpart Da units -- those on which construction, reconstruction,
    or modification commenced after May 3, 2011 -- to test for
    condensable particulate matter. See 
    id. at 9458.
    Finally, the rule
    did not allow the use of state-law affirmative defenses. 
    Id. at 9433.
    Thereafter, UARG and the State of Texas filed petitions for
    agency reconsideration as well as for judicial review. EPA has
    not yet acted on the petitions for reconsideration. The petitions
    for judicial review are now before us.
    II
    We begin with two issues regarding the scope of our
    review: the law that determines which of the petitioners’
    challenges are properly before us, and the standards for
    reviewing those challenges that are.
    A
    This court’s general view is that “a pending petition for
    [agency] rehearing . . . render[s] the underlying agency action
    nonfinal (and hence unreviewable) with respect to the filing
    party.” United Transp. Union v. ICC, 
    871 F.2d 1114
    , 1116
    (D.C. Cir. 1989); see, e.g., Clifton Power Corp. v. FERC, 
    294 F.3d 108
    , 110-12 (D.C. Cir. 2002). In the 1990 Amendments to
    the Clean Air Act, however, Congress made clear that this does
    not apply to challenges to rules promulgated under the Act. A
    provision of 42 U.S.C. § 7607(b)(1) states: “The filing of a
    petition for reconsideration by the Administrator of any
    9
    otherwise final rule or action shall not affect the finality of such
    rule or action for purposes of judicial review . . . .” 42 U.S.C.
    § 7607(b)(1). The Senate Report accompanying the Clean Air
    Act Amendments confirms that the purpose of that provision
    was to “overrule,” in the context of the Clean Air Act, the
    holding in West Penn Power Co. v. EPA, 
    860 F.2d 581
    , 583 (3d
    Cir. 1988), that a pending petition for reconsideration deprives
    an agency action of finality. S. REP. NO. 101-228, at 3755
    (1989). West Penn was one of the cases upon which this court
    relied in adopting our general view. See United Transp. 
    Union, 871 F.2d at 1117-18
    .
    Nonetheless, even under the Clean Air Act, a party may not
    raise for judicial review objections to a rule that it raised for the
    first time in a petition for agency reconsideration -- at least until
    that petition is resolved. The Act states:
    Only an objection to a rule or procedure which was
    raised with reasonable specificity during the period for
    public comment . . . may be raised during judicial
    review. If the person raising an objection can
    demonstrate to the Administrator that it was
    impracticable to raise such objection within such time
    or if the grounds for such objection arose after the
    period for public comment . . . and if such objection is
    of central relevance to the outcome of the rule, the
    Administrator shall convene a proceeding for
    reconsideration of the rule . . . . If the Administrator
    refuses to convene such a proceeding, such person may
    seek review of such refusal in the United States court
    of appeals for the appropriate circuit . . . .
    42 U.S.C. § 7607(d)(7)(B).
    10
    The first sentence of this subsection flatly states that “[o]nly
    an objection to a rule or procedure which was raised . . . during
    the period for public comment . . . may be raised during judicial
    review.” Standing alone, the sentence indicates that an
    objection raised for the first time in a petition for
    reconsideration may not be raised in court, because such an
    objection was, by definition, not raised “during the period for
    public comment.”
    The second and third sentences create a limited exception
    to the bar imposed by the first. As the second sentence states, if
    it was impracticable to raise a particular objection during the
    comment period or the grounds for the objection arose after that
    period, and if the objection is of central relevance to the
    outcome of the rule, “the Administrator shall convene a
    proceeding for reconsideration of the rule.” Presumably, a party
    can seek judicial review of the outcome of such a
    reconsideration proceeding. But that sentence (together with the
    one that precedes it) would be pointless if a court could hear an
    objection raised for the first time in a petition for
    reconsideration before the proceeding was completed.
    The third sentence indicates what a petitioner may do “if the
    Administrator refuses to convene” a reconsideration proceeding.
    In that circumstance, a petitioner “may seek review of such
    refusal in the United States court of appeals.” And one thing the
    court may then do, if the predicates for reconsideration set out
    in the second sentence are satisfied, is vacate the refusal and
    direct the Administrator to convene a reconsideration
    proceeding. Likewise, when that proceeding is completed, the
    court presumably can hear a petition for review of the outcome.
    But once again, that sentence (together with the two that precede
    it) would be pointless if a court could hear a new objection
    before those procedural steps were completed.
    11
    In sum, although the filing of a petition for reconsideration
    does not render a Clean Air Act rule nonfinal for purposes of
    judicial review, the only objections that may immediately be
    raised upon judicial review are those that were raised during the
    public comment period. Objections raised for the first time in
    a petition for reconsideration must await EPA’s action on that
    petition. See Oklahoma v. EPA, 
    723 F.3d 1201
    , 1214-15 (10th
    Cir. 2013); see generally Appalachian Power Co. v. EPA, 
    249 F.3d 1032
    , 1055, 1065 (D.C. Cir. 2001); North Dakota v. EPA,
    
    730 F.3d 750
    , 770-71 (8th Cir. 2013).
    At oral argument, UARG maintained that, even if it cannot
    obtain judicial review of substantive challenges raised for the
    first time in a still-pending petition for reconsideration, it can
    obtain judicial review of procedural challenges raised for the
    first time in such a petition. But the language of the Clean Air
    Act forecloses that argument. See 42 U.S.C. § 7607(d)(7)(B)
    (“Only an objection to a rule or procedure which was raised
    with reasonable specificity during the period for public
    comment . . . may be raised during judicial review.” (emphasis
    added)); see also Appalachian Power 
    Co., 249 F.3d at 1055
    ;
    
    Oklahoma, 723 F.3d at 1214-15
    . Accordingly, because EPA has
    not yet resolved the petitioners’ petitions for reconsideration, the
    only objections that are properly before us are those the
    petitioners made during the public comment periods.
    B
    We may vacate a final rule promulgated under the Clean
    Air Act if it is “arbitrary, capricious, an abuse of discretion, or
    otherwise not in accordance with law.”                 42 U.S.C.
    § 7607(d)(9)(A). To determine whether a rule is arbitrary or
    capricious, we apply the same standard of review that we apply
    under the Administrative Procedure Act (APA), 5 U.S.C.
    § 706(2)(A). See Allied Local & Reg’l Mfrs. Caucus v. EPA,
    12
    
    215 F.3d 61
    , 68 (D.C. Cir. 2000). “[W]e must affirm the EPA’s
    rules if the agency has considered the relevant factors and
    articulated a rational connection between the facts found and the
    choice made.” 
    Id. (internal quotation
    marks omitted).
    As under the APA, we may also vacate a rule under the
    Clean Air Act if it was promulgated “without observance of
    procedure required by law.” 42 U.S.C. § 7607(d)(9)(D); see 5
    U.S.C. § 706(2)(D). But the Clean Air Act tacks on three
    additional conditions. To vacate a Clean Air Act rule on the
    ground that the agency failed to observe a procedural
    requirement, we must also find that “(i) such failure to observe
    such procedure is arbitrary or capricious, (ii) the requirement of
    paragraph (7)(B) has been met, and (iii) the condition of the last
    sentence of paragraph (8) is met.” 42 U.S.C. § 7607(d)(9)(D).
    The second condition is a reference to the requirement of
    § 7607(d)(7)(B), which we discussed in Part II.A above. The
    third condition provides that “the court may invalidate the rule
    only if the errors were so serious and related to matters of such
    central relevance to the rule that there is a substantial likelihood
    that the rule would have been significantly changed if such
    errors had not been made.” 
    Id. § 7607(d)(8).
    III
    The petitioners raise several challenges that are not properly
    before us. They object to the following: the 2012 rule’s
    condensable particulate matter testing requirement for Subpart
    Da units; the rule’s establishment of a different frequency for
    periodic visual opacity inspections under Subparts D, Db, and
    Dc than under Subpart Da; and the agency’s suggestion that it
    would permit the use of state-law affirmative defenses in the
    context of the mercury and air toxics (MATS) emission
    standards for coal- and oil-fired electric utility steam generating
    units (EGUs), issued pursuant to 42 U.S.C. § 7412, while not
    13
    allowing such defenses in the context of new source
    performance standards under § 7411. It is undisputed the
    petitioners did not make these objections during the public
    comment period. Although they did raise them in their petitions
    for reconsideration, those petitions remain pending before the
    agency. Accordingly, for the reasons discussed in Part II.A,
    these challenges are not properly before us.4
    The following subsections address the objections that the
    petitioners did raise during the comment period.
    A
    UARG challenges the requirement -- included in the 2009
    rule and reaffirmed in the 2012 rule -- that Subparts D, Db, and
    Dc boilers emitting more than 0.03 lb/MMBtu of particulate
    matter remain subject to the opacity standard and must install
    COMS or perform periodic visual opacity inspections, even if
    they use particulate matter CEMS.
    4
    It is true that our cases have said EPA retains a “duty to examine
    key assumptions as part of its affirmative burden of promulgating and
    explaining a non-arbitrary, non-capricious rule and therefore . . . must
    justify [such an] assumption even if no one objects to it during the
    comment period.” Okla. Dep’t of Envtl. Quality v. EPA, 
    740 F.3d 185
    , 192 (D.C. Cir. 2014) (alteration in original) (internal quotation
    marks omitted); see, e.g., Ne. Md. Waste Disposal Auth. v. EPA, 
    358 F.3d 936
    , 948 (D.C. Cir. 2004). But unlike the petitioners in the cited
    cases, the petitioners here did not merely fail to object to assumptions
    (whether “key” or not) underlying the requirements and distinctions
    they now challenge in court; rather, they did not object to those
    requirements or distinctions at all. Although the petitioners may have
    had good reason for not raising those objections during the
    rulemaking, judicial review must nonetheless await EPA’s action on
    their petitions for reconsideration. 
    See supra
    Part II.A; infra note 7.
    14
    1. UARG contends that continuing to subject boilers
    emitting more than 0.03 lb/MMBtu of particulate matter to an
    opacity standard and opacity monitoring requirements, while
    exempting boilers emitting that amount or less, was arbitrary
    and capricious. We disagree. In its 2009 rule, EPA explained
    that sources emitting 0.03 lb/MMBtu or less of particulate
    matter “will operate with little or no visible emissions,” and thus
    “an opacity standard is no longer necessary for these sources.”
    2009 Rule, 74 Fed. Reg. at 5073. “At this emission rate,” the
    agency said, the existence of any “visible emissions may
    indicate that the [particulate matter] control device is not
    operating properly.” 
    Id. at 5074.
    Hence, for a source that is
    meeting this emission standard, no opacity standard is needed
    because any visible opacity will indicate improper operation.
    By contrast, units emitting more than 0.03 lb/MMBtu of
    particulate matter “may have some visible emissions” even if
    their particulate matter control devices are operating properly.
    
    Id. Since particulate
    matter “CEMS readings cannot be verified
    as readily as other CEMS, and since recalibration requires
    [particulate matter] performance tests, baseline opacity readings
    can be a valuable secondary check on control device
    performance and [particulate matter] emissions.”               
    Id. Accordingly, the
    agency reasonably concluded that a unit
    emitting more than 0.03 lb/MMBtu should remain “subject to an
    opacity limit” and “use a COMS or perform periodic visual
    inspections to comply with the opacity standard” to verify that
    the pollution control and monitoring systems are operating
    properly. Id.5

    The petitioners maintain that, in the 2012 rule, EPA renounced
    this rationale for subjecting boilers emitting more than 0.03 lb/MMBtu
    of particulate matter to an opacity standard. We disagree. The agency
    did add another explanation in its response to comments, but nothing
    in that response suggests that it renounced its earlier rationale. See
    15
    UARG also contends that EPA was unreasonable, not just
    in retaining an opacity standard for units emitting more than
    0.03 lb/MMBtu of particulate matter, but also in requiring them
    to use a COMS or perform periodic visual opacity inspections.
    But as just explained, the purpose of retaining the opacity
    standard for such a unit is to provide a real-time check to ensure
    that its particulate matter control device is functioning properly.
    See 2009 Rule, 74 Fed. Reg. at 5073-74; 2008 Proposal, 73 Fed.
    Reg. at 33,646 n.1. Using a COMS or performing periodic
    visual opacity inspections provides that check. See 
    id. Because EPA
    has articulated a reasonable explanation for requiring
    opacity monitoring, petitioner’s challenge to this requirement
    fails.
    We also reject UARG’s related contention that EPA’s
    action was arbitrary and capricious because it failed to address
    “the impacts of the periodic visible emissions testing on the
    Subpart D units it had proposed to exempt from the standard, but
    did not exempt in the final rule.” Pet’rs’ Br. 35. Whether or not
    a failure to consider the burden imposed on those units would
    have been arbitrary and capricious, the contention fails because
    EPA did consider the burden imposed by its visual opacity
    inspection requirement. See 2009 Rule, 74 Fed. Reg. at 5074;
    see also 2008 Proposal, 73 Fed. Reg. at 33,643 (noting that the
    proposal, which included visual opacity inspection requirements,
    “would not significantly change our original projections for the
    rule’s compliance costs, . . . burden on industry, or the number
    of affected facilities”); 
    id. at 33,645
    (noting that “the use of a
    digital camera system” to comply with the opacity monitoring
    requirements “would also reduce compliance costs”); 2012 Rule,
    EPA, Response to Public Comments on Rule Amendments Proposed
    May 3, 2011 (73 FR 33642) [hereinafter 2011 Response to
    Comments] at 13-14 (Dec. 2011) (J.A. 211-12).
    16
    77 Fed. Reg. at 9425 (analyzing the power industry’s
    compliance costs).
    2. UARG further contends that, in promulgating the 2009
    rule, EPA violated the Clean Air Act’s rulemaking provisions.
    According to UARG, in 2008 “EPA proposed one rule (the full
    opacity exemption) based on its longstanding positions . . . , and
    then adopted a very different rule without any notice of its new
    rationale or positions.” Pet’rs’ Br. 31. But even assuming that
    EPA did stumble procedurally during the rulemaking for the
    2009 rule, it made up for any procedural error during the
    rulemaking for the 2012 rule. There is no dispute that, during
    the latter, EPA offered all interested parties an opportunity to
    comment on both the opacity standard and the opacity
    monitoring requirements.         Because thereafter EPA re-
    promulgated the same standard and requirements, UARG’s
    procedural objection to the allegedly inadequate notice and
    opportunity to comment is moot. See NRDC v. U.S. Nuclear
    Regulatory Comm’n, 
    680 F.2d 810
    , 813-14 (D.C. Cir. 1982); see
    also Fund for Animals, Inc. v. Hogan, 
    428 F.3d 1059
    , 1063-64
    (D.C. Cir. 2005). So, too, is its contention that EPA failed to
    respond to comments on the 2008 proposal. See NRDC v. U.S.
    Nuclear Regulatory 
    Comm’n, 680 F.2d at 813-14
    .6
    6
    UARG also argues that EPA violated the Paperwork Reduction
    Act by failing to submit to the Office of Management and Budget an
    information collection request to support its condensable particulate
    matter testing requirement. See 44 U.S.C. § 3507(a). But even if that
    were true, a violation of the Paperwork Reduction Act does not afford
    an independent cause of action; it merely serves as a defense to an
    enforcement action. See 
    id. § 3512;
    Dithiocarbamate Task Force v.
    EPA, 
    98 F.3d 1394
    , 1405 (D.C. Cir. 1996); see also, e.g., Sutton v.
    Providence St. Joseph Med. Ctr., 
    192 F.3d 826
    , 844 (9th Cir. 1999).
    No such action is before us.

    B
    Texas’ petition for review challenges EPA’s refusal to
    allow state-law affirmative defenses against the enforcement of
    new source performance standards.
    As noted earlier, see supra Part I, EPA’s 2011 notice
    proposed adding an affirmative defense to civil penalties when
    a facility exceeds emission limits as a result of a malfunction.
    See 2011 Proposal, 76 Fed. Reg. at 25,064. EPA proposed that
    the defense be available only “where the event that causes an
    exceedance of the emission limit” is “sudden, infrequent, not
    reasonably preventable and not caused by poor maintenance and
    or careless operation.” 
    Id. In its
    comments during the
    rulemaking, Texas asked EPA to consider allowing states to use
    their own state-law affirmative defenses in lieu of the federal
    defense that EPA proposed. Specifically, Texas wanted to use
    the affirmative defense provisions in its State Implementation
    Plan (SIP), which EPA had previously approved under a
    different Clean Air Act provision, 42 U.S.C. § 7410. The 2012
    final rule permitted the federal defense only.
    Texas maintains that EPA did not explain why it declined
    to approve Texas’ use of a state-specific affirmative defense for
    the new source performance standards under 42 U.S.C. § 7411,
    when it had approved such a defense in its SIP under § 7410.
    But EPA did explain: Unlike some other Clean Air Act
    standards, new source performance standards are not
    incorporated into SIPs as state-promulgated regulations. Rather,
    they are federal standards to which SIP affirmative defense
    provisions are inapplicable. See 2011 Response to Comments
    at 26 (J.A. 215).
    Texas protests that this explanation is arbitrary and
    capricious because EPA suggested, in responding to comments
    18
    in a different rulemaking, that it would permit state-specific
    affirmative defenses with respect to different emission standards
    -- the mercury and air toxics (MATS) emission standards for
    coal- and oil-fired EGUs, issued pursuant to 42 U.S.C. § 7412.
    Although EPA’s brief offers the agency’s explanation for the
    difference (based on differences between the state-delegation
    aspects of the new source performance and MATS rules, see
    EPA Br. 30-32), we do not address that explanation. As we
    noted above, supra Part III (introduction), Texas did not bring
    this alleged inconsistency to EPA’s attention until its petition for
    reconsideration. As a consequence, it may not raise this
    objection for judicial review until that petition is resolved. 
    See supra
    Part II.A.7
    IV
    For the foregoing reasons, the petitions for review are
    Denied.
    7
    It does appear that Texas had good reason for not raising the
    point during the rulemaking: EPA’s response regarding the MATS
    comments was not published until the public comment period for the
    new source performance standards rule had closed. See EPA’s
    Responses to Public Comments on EPA’s National Emission
    Standards for Hazardous Air Pollutants from Coal- and Oil-Fired
    EGUs (Dec. 2011) (J.A. 167); 2011 Proposal, 76 Fed. Reg. at 24,976
    (“Comments must be received on or before July 5, 2011.”). But as we
    explained in Part II.A, although this may qualify Texas for the limited
    exception to the statutory bar against raising objections not raised
    during a rulemaking, see 42 U.S.C. § 7607(d)(7)(B), the State must
    nonetheless wait to raise its objection until EPA acts on its petition for
    reconsideration. See 
    Oklahoma, 723 F.3d at 1214-15
    ; Appalachian
    
    Power, 249 F.3d at 1065
    .
    KAVANAUGH, Circuit Judge, concurring: I join the Court’s
    opinion. I note simply that the Section 7607 exhaustion/finality
    rule we describe today likely should not be considered
    jurisdictional under the Supreme Court’s recent cases that have
    tightened the definition of when a rule is considered
    jurisdictional. See generally Sebelius v. Auburn Regional
    Medical Center, 
    133 S. Ct. 817
    , 824 (2013) (“To ward off
    profligate use of the term jurisdiction, we have adopted a readily
    administrable bright line for determining whether to classify a
    statutory limitation as jurisdictional. We inquire whether
    Congress has clearly stated that the rule is jurisdictional; absent
    such a clear statement, we have cautioned, courts should treat
    the restriction as nonjurisdictional in character.”) (citations,
    internal quotation marks, and alteration omitted); Gonzalez v.
    Thaler, 
    132 S. Ct. 641
    , 648 (2012) (“Recognizing our less than
    meticulous use of the term in the past, we have pressed a stricter
    distinction between truly jurisdictional rules, which govern a
    court’s adjudicatory authority, and nonjurisdictional claim-
    processing rules, which do not.”) (internal quotation marks
    omitted); Henderson ex rel. Henderson v. Shinseki, 
    131 S. Ct. 1197
    , 1202-03 (2011) (“We have urged that a rule should not be
    referred to as jurisdictional unless it governs a court’s
    adjudicatory capacity, that is, its subject-matter or personal
    jurisdiction. Other rules, even if important and mandatory, we
    have said, should not be given the jurisdictional brand.”)
    (citations omitted).
    To be sure, at least one case of ours has referred to the
    Section 7607 rule as jurisdictional. See National Association of
    Clean Water Agencies v. EPA, 
    734 F.3d 1115
    , 1158 (D.C. Cir.
    2013). But our statement in that case was based on a prior case
    that pre-dated some of the Supreme Court’s more recent
    pronouncements on the jurisdiction label. Of course, the
    question of whether such a rule is jurisdictional matters only in
    those cases where the agency has waived or forfeited reliance on
    2
    the rule, which is to say not often. Although we do not need to
    address the question in this case, in an appropriate case where it
    makes a difference, we may want to ensure that our case law on
    the jurisdictional status of this particular exhaustion/finality rule
    has kept pace with the Supreme Court’s case law on when a rule
    should be considered jurisdictional.
