    FLOYD, Circuit Judge:
    In this case, we consider the bounds of a federal court’s authority under the Clean
    Air Act (CAA) to correct an alleged failure by the U.S. Environmental Protection Agency
    (EPA) to perform a non-discretionary, CAA-based act or duty.              See 42 U.S.C.
    § 7604(a)(2). The precise issue before us is whether this authority extends to review of
    the EPA’s management of its continuous duty to evaluate the potential employment
    impact of CAA administration and enforcement. See 42 U.S.C. § 7621(a). We hold that
    it does not.
    I.
    In 1977, after extensive public debate about the effects of the CAA’s
    environmental rules on employment, Congress enacted Section 321 of the CAA as a
    mechanism for reviewing those effects. See H.R. Rep. No. 95-294, at 316–18 (1977),
    reprinted in 1977 U.S.C.C.A.N. 1077, 1395–97.
    At issue in this case is Section 321(a) of the CAA, 42 U.S.C. § 7621(a), which
    directs the EPA to continuously evaluate the potential employment impact of CAA
    administration and enforcement. Section 321(a) provides:
    The [EPA] Administrator shall conduct continuing evaluations of potential
    loss or shifts of employment which may result from the administration or
    enforcement of the provision of this chapter and applicable implementation
    plans, including where appropriate, investigating threatened plant closures
    or reductions in employment allegedly resulting from such administration
    or enforcement.
    42 U.S.C. § 7621(a).
    5
    In 2014, Murray Energy Corporation and related companies (collectively,
    “Murray”) filed the instant suit against the EPA Administrator, alleging a failure to
    comply with Section 321(a). Murray filed its suit under Section 304(a)(2) of the CAA,
    42 U.S.C. § 7604(a)(2), which in pertinent part provides: “[A]ny person may commence
    a civil action on his own behalf . . . against the [EPA] Administrator where there is
    alleged a failure of the Administrator to perform any act or duty under [the CAA] which
    is not discretionary with the Administrator.”     Murray’s suit requested an injunction
    (1) ordering the EPA to conduct Section 321(a) evaluations; and (2) prohibiting the EPA
    from engaging in certain regulatory activities until it had conducted such evaluations.
    At the outset of the litigation, the EPA moved to dismiss Murray’s suit on
    jurisdictional grounds. The EPA first argued that its Section 321(a) duty was not a non-
    discretionary duty cognizable under Section 304(a)(2). In a subsequent filing, the EPA
    added that Murray lacked standing to challenge the EPA’s alleged non-compliance with
    Section 321(a). The district court rejected both of the EPA’s jurisdictional arguments,
    and declined to dismiss Murray’s suit at the pleading stage.
    Subsequently, the EPA moved for summary judgment and simultaneously
    proffered fifty-three documents to prove the agency’s compliance with Section 321(a).
    The EPA’s documents—which the agency conceded had not been prepared explicitly for
    the purpose of Section 321(a) compliance—included regulatory impact analyses,
    economic impact analyses, white papers, and other reports. The EPA asked the district
    court to grant summary judgment in its favor on the basis of its proffer or, in the
    6
    alternative, that the court grant summary judgment in Murray’s favor if it were to
    conclude that the agency’s proffer was insufficient.
    Murray moved to hold in abeyance the EPA’s motion for summary judgment
    pending the completion of discovery. The district court granted Murray’s motion, and
    discovery continued. 1
    At the close of discovery, the EPA filed a renewed motion for summary judgment.
    The EPA reiterated its position that Murray’s suit was not judicially cognizable and that,
    even if it was, Murray lacked standing to bring its suit. Finally, the EPA renewed its
    request for an up-or-down merits ruling that its proffer demonstrated compliance with
    Section 321(a). In light of the continuous nature of the EPA’s duty under Section 321(a),
    the EPA’s proffer at the renewed summary judgment stage increased from fifty-three to
    sixty-four relevant documents.
    On October 17, 2016, the district court issued an opinion and order granting
    summary judgment in Murray’s favor. Murray Energy Corp. v. McCarthy, No. 5:14-cv-
    39, 
    2016 WL 6083946
    (N.D.W. Va. Oct. 17, 2016) (“Summary Judgment Opinion”).
    1
    At one point during discovery, the district court refused to preclude a noticed
    deposition of the EPA Administrator that was designed to address an alleged conflict
    between the EPA’s litigation position that it had complied with Section 321(a) and prior
    concessions by the EPA to Congress that it had not been conducting evaluations for the
    purpose of Section 321(a) compliance. This Court, however, ultimately granted a writ of
    mandamus precluding the noticed deposition. In re McCarthy, 636 F. App’x 142 (4th
    Cir. 2015). We explained that the claim that the EPA had not prepared documents with
    the intent of Section 321(a) compliance was not in conflict with the claim that the agency
    had nonetheless prepared documents with the effect of Section 321(a) compliance, as
    nothing in Section 321(a) conditions compliance on intent. 
    Id. at 143–44.
    7
    The court first held that Section 321(a) creates a non-discretionary duty that gives rise to
    Section 304(a)(2) jurisdiction. The court then held that Murray possessed standing to
    seek redress for alleged procedural, economic, and informational injuries.
    Finally, the court ruled in Murray’s favor on the merits. The court read Section
    321(a) as obligating the EPA to assess the actual, site-specific employment effects of
    CAA implementation. The court concluded that the EPA’s proffered documents did not
    satisfy this requirement. In light of this conclusion, the court ordered the EPA to file a
    “plan and schedule for compliance with [Section] 321(a) both generally and in the
    specific area of the effects of its regulations on the coal industry.” 
    Id. at *28.
    On October 31, 2016, the EPA submitted a response to the Summary Judgment
    Opinion.       The EPA’s response opened with a set of objections to the court’s
    jurisdictional, merits, and preliminary remedial rulings. Nonetheless, the EPA’s response
    ultimately set forth a proposed plan and schedule to supplement its performance of
    Section 321(a) evaluations. The EPA’s proposal drew sharp criticism from Murray.
    On December 14, 2016—before the district court had resolved the issue of an
    appropriate remedy—Mon Valley Clean Air Coalition and related non-governmental
    organizations (collectively, “Mon Valley”) filed a motion for leave to intervene in
    support of the EPA. Specifically, Mon Valley claimed to have an interest in the EPA’s
    regulatory activities under the CAA, and sought intervention under Federal Rule of Civil
    Procedure 24 to prevent Section 321(a) from being used to stay or impede certain CAA
    regulations.
    8
    On January 11, 2017, the district court issued an opinion and order outlining the
    appropriate remedy. Murray Energy Corp. v. McCarthy, No. 5:14-cv-39, 
    2017 WL 150511
    (N.D.W. Va. Jan. 11, 2017) (“Remedial Opinion”). In its opinion, the court
    rejected the EPA’s proposed plan and schedule, and opted to craft its own remedy. The
    court’s remedy was an extensive injunction ordering the EPA to conduct an evaluation
    identifying, inter alia, facilities that are at risk of closure or reductions in employment
    because of the EPA’s coal-related regulatory activities under the CAA, the past
    employment ramifications of those activities, and the impact of CAA-related employment
    losses and shifts on families and communities. 
    Id. at *11.
    The court stopped short, however, of granting Murray complete relief.
    Specifically, the court denied Murray’s request for an injunction staying the effective
    date of certain pending CAA regulations and limiting the EPA’s authority to propose or
    finalize new CAA regulations pending the agency’s compliance with Section 321(a).
    The court reasoned that it lacked the authority to grant such relief in light of Section
    321(d), 42 U.S.C. § 7621(d), which in pertinent part provides: “Nothing in [Section 321]
    shall be construed to require or authorize the [EPA] Administrator . . . to modify or
    withdraw any requirement imposed or proposed to be imposed under this chapter.” 
    Id. (quoting 42
    U.S.C. § 7621(d)).
    On January 17, 2017, the district court issued an order denying as moot Mon
    Valley’s motion to intervene, explaining that the court in its Remedial Opinion had
    already denied the relief that Mon Valley opposed. Murray Energy Corp. v. McCarthy,
    No. 5:14-cv-39 (N.D.W. Va. Jan. 17, 2017), J.A. 288–89 (“Intervention Order”). The
    9
    court’s order also administratively closed the case, but noted that the court would
    continue to supervise the implementation and enforcement of its injunction against the
    EPA.
    The EPA noted timely appeals of the Summary Judgment Opinion, the Remedial
    Opinion, and the Intervention Order. On appeal, the EPA challenges the district court’s
    adverse jurisdictional, merits, and remedial rulings. 2 In addition, Mon Valley noted a
    timely appeal of the Intervention Order. On appeal, Mon Valley challenges the district
    court’s denial of the organization’s motion to intervene. We consolidated the EPA’s set
    of appeals and Mon Valley’s appeal, and we examine each in turn.
    II.
    We begin by reviewing the district court’s conclusion that Section 304(a)(2)
    authorizes Murray’s Section 321(a)-based suit against the EPA. Because this conclusion
    implicates the subject matter jurisdiction of the federal courts, we review it de novo.
    Lontz v. Tharp, 
    413 F.3d 435
    , 439 (4th Cir. 2005). We hold that the district court erred in
    concluding that it could adjudicate Murray’s suit pursuant to Section 304(a)(2).
    Section 304(a)(2) authorizes suit to correct “a failure of the [EPA] Administrator
    to perform any act or duty under [the CAA] which is not discretionary with the
    Administrator.”    42 U.S.C. § 7604(a)(2).        We have construed Section 304(a)(2)
    “narrowly” by confining its scope to the enforcement of legally required acts or duties of
    2
    Neither the EPA nor Murray contests the district court’s decision to partially
    deny Murray injunctive relief.
    10
    a specific and discrete nature that precludes broad agency discretion. Monongahela
    Power Co. v. Reilly, 
    980 F.2d 272
    , 276 n.3 (4th Cir. 1992) (citing, inter alia, Envtl. Def.
    Fund v. Thomas, 
    870 F.2d 892
    , 899 (2d Cir. 1989); Mountain States Legal Found. v.
    Costle, 
    630 F.2d 754
    , 766 (10th Cir. 1980); Kennecott Copper Corp. v. Costle, 
    572 F.2d 1349
    , 1355 (9th Cir. 1978)).
    Our narrow construction reduces the risk of judicial disruption of complex agency
    processes—a vice that Congress appeared intent on avoiding by writing a non-
    discretionary requirement into the statute. See 
    Kennecott, 572 F.2d at 1353
    (explaining
    that Section 304(a)(2)’s “legislative history reveals that Congress recognized the potential
    for disruption of the administrative process inherent in a broad grant of jurisdiction,” and
    inserted the non-discretionary requirement into the statute in order to minimize such
    disruption (citing S. Comm. on Public Works, 93d Cong., 2d Sess., A Legislative History
    of the Clean Air Amendments of 1970, Serial No. 93-18, Vol. 1 at 278 (1970))); accord
    Nat. Res. Def. Council, Inc. v. Thomas, 
    885 F.2d 1067
    , 1073 (2d Cir. 1989).
    Moreover, our narrow construction gives Section 304(a)(2) a scope similar to that
    of both the traditional mechanism for judicial review of agency operations, the writ of
    mandamus, and the modern mechanism for judicial review of many types of agency
    inaction, Section 706(1) of the Administrative Procedure Act (APA), 5 U.S.C. § 706(1).
    See Norton v. S. Utah Wilderness All., 
    542 U.S. 55
    , 63–64 (2004) (describing mandamus
    relief as “normally limited to enforcement of a specific, unequivocal command, the
    ordering of a precise, definite act about which an official had no discretion whatever,”
    and further explaining that “a claim under § 706(1) can proceed only where a plaintiff
    11
    asserts that an agency failed to take a discrete agency action that it is required to take”)
    (internal quotation marks, citations, and alterations omitted).
    With this understanding in mind, we turn to the question of whether Section
    304(a)(2) authorizes suits to enforce the duty outlined in Section 321(a). As described
    above, Section 321(a) provides that the EPA “shall conduct continuing evaluations of
    potential loss or shifts of employment which may result from the administration or
    enforcement of the provision of [the CAA] and applicable implementation plans,
    including where appropriate, investigating threatened plant closures or reductions in
    employment allegedly resulting from such administration or enforcement.” 42 U.S.C.
    § 7621(a). This statutory language, in our view, does not impose on the EPA a specific
    and discrete duty amenable to Section 304(a)(2) review.
    Rather, Section 321(a)—when read as a whole—imposes on the EPA a broad,
    open-ended statutory mandate. To begin, Section 321(a) calls for evaluations of the
    potential employment impact of regulatory and enforcement activities—a duty which
    demands the exercise of agency judgment. See Webster’s Third New Int’l Dictionary 786
    (1976) (defining “evaluate” as “to examine and judge concerning the worth, quality,
    significance, amount, degree, or condition of”).         Moreover, the relevant class of
    regulatory and enforcement activities is extensive—it is the entire set of actions
    administering and enforcing the CAA.         Finally, and perhaps most importantly, the
    required evaluations are not confined to a discrete time period, but instead are to be
    conducted on a continuing basis. Cf. Lujan v. Nat’l Wildlife Fed’n, 
    497 U.S. 871
    , 890
    (1990) (refusing to treat a certain set of “continuing (and thus constantly changing)
    12
    operations of the [Bureau of Land Management]” as an “agency action” reviewable under
    the APA).
    The open-ended nature of Section 321(a)’s command is further confirmed by what
    the statute does not say. Section 321(a) calls for evaluations without, for the most part,
    specifying guidelines and procedures relevant to those evaluations. 3         Furthermore,
    Section 321(a) establishes no start-dates, deadlines, or any other time-related instructions
    to guide the EPA’s continuous evaluation efforts.
    The EPA is thus left with considerable discretion in managing its Section 321(a)
    duty. The agency gets to decide how to collect a broad set of employment impact data,
    how to judge and examine this extensive data, and how to manage these tasks on an
    ongoing basis. A court is ill-equipped to supervise this continuous, complex process. Cf.
    Vill. of Bald Head Island v. U.S. Army Corps of Eng’rs, 
    714 F.3d 186
    , 194 (4th Cir.
    2013) (explaining, in an APA case, that “the obvious inability for a court to function in
    such a day-to-day managerial role over agency operations” justifies “limit[ing] judicial
    review to discrete agency action” (citing 
    Norton, 542 U.S. at 62
    –64)).
    3
    The only detail of the evaluation duty that Section 321(a) provides is that the
    duty includes “investigating threatened plant closures or reductions in employment
    allegedly resulting from [CAA] administration or enforcement.” 42 U.S.C. § 7621(a).
    However, Section 321(a) explicitly notes that these investigations need only be conducted
    “where appropriate,” 
    id., and thereby
    renders them a matter of agency discretion
    unreviewable under Section 304(a)(2). See Guilford Cty. Cmty. Action Program, Inc. v.
    Wilson, 
    348 F. Supp. 2d 548
    , 556 (M.D.N.C. 2004) (holding that a statute providing that
    a state “shall” offer training and assistance “if appropriate” leaves the state with
    “discretion in providing training and assistance”); cf. Michigan v. EPA, 
    135 S. Ct. 2699
    ,
    2707 (2015) (explaining that “‘appropriate’ is the classic broad and all-encompassing
    term”—one that “leaves agencies with flexibility”) (internal quotation marks omitted).
    13
    On a final note, we add that Section 321(a)’s poor fit for judicial review is
    underscored when the statute is viewed alongside other CAA provisions that offer
    discrete directives accompanied by specific guidance on matters of content, procedure,
    and timing. For example, the very next provision, Section 321(b), 42 U.S.C. § 7621(b),
    directs the EPA to investigate an employee’s claim that an actual or proposed CAA
    requirement adversely affected his or her employment, and establishes a framework for
    related public hearings, reports, and findings of fact. Meanwhile, Section 317, 42 U.S.C.
    § 7617, directs the EPA to prepare economic impact assessments for enumerated agency
    actions, and outlines deadlines, procedural details, and specific factors for analysis.
    Section 321(a) fails to offer such clear instructions that could serve as a solid basis for
    judicial review.
    Accordingly, we hold that Section 304(a)(2) does not authorize the instant suit by
    Murray against the EPA, and that the district court thus lacked jurisdiction over the suit. 4
    Consequently, we vacate the district court’s judgments insofar as they impact the EPA,
    and remand this matter to the district court with instructions that it dismiss Murray’s suit
    for want of jurisdiction. See Steel Co v. Citizens for a Better Env’t, 
    523 U.S. 83
    , 94, 101
    4
    Murray briefly suggests that—setting aside Section 304(a)(2) of the CAA—
    jurisdiction may be conferred to the district court in this case by the APA, see 5 U.S.C.
    § 702 et seq., or by the mandamus statute, see 28 U.S.C. § 1361. Assuming arguendo
    that the APA or the mandamus statute could ever authorize judicial review of the EPA’s
    compliance with the CAA, we conclude that those provisions do not do so in this case.
    As explained above, those provisions only empower a court to respond to an agency’s
    failure to act in the face of a clear-cut duty, see 
    Norton, 542 U.S. at 63
    –64; they do not
    empower a court to supervise an agency’s compliance with a broad statutory mandate of
    the sort contained in Section 321(a), see 
    id. at 66–67.
    14
    (1998) (“Without jurisdiction the court cannot proceed at all in any cause. Jurisdiction is
    power to declare the law, and when it ceases to exist, the only function remaining to the
    court is that of announcing the fact and dismissing the cause.” (quoting Ex parte
    McCardle, 74 U.S. (7 Wall.) 506, 514 (1868))). In light of this disposition, we decline to
    address the EPA’s challenges to the district court’s standing, merits, and remedial
    rulings. 5
    III.
    We next turn to Mon Valley’s appeal of the district court’s denial of its motion to
    intervene. We conclude that this appeal is moot, and must therefore be dismissed.
    “A case becomes moot, and thus deprives federal courts of subject matter
    jurisdiction, ‘when the issues presented are no longer ‘live’ or the parties lack a legally
    cognizable interest in the outcome.’” Pashby v. Delia, 
    709 F.3d 307
    , 316 (4th Cir. 2013)
    (quoting Simmons v. United Mortg. & Loan Inv. LLC, 
    634 F.3d 754
    , 763 (4th Cir. 2011)).
    We have recently described the circumstances in which an appeal of a denial of a motion
    to intervene is not rendered moot by the dismissal of the underlying action: “[W]e can
    provide an effective remedy on appeal and therefore have jurisdiction” only “[1] when
    5
    We note one additional point. In its appellate briefing, Murray claims that the
    EPA’s alleged dereliction of its Section 321(a) duty constitutes “agency action
    unreasonably delayed” that is actionable under Section 304(a) of the CAA, 42 U.S.C.
    § 7604(a). We decline to consider this claim because Murray failed to plead it in its
    complaint. See S. Walk at Broadlands Homeowners Ass’n, Inc. v. OpenBand at
    Broadlands, LLC, 
    713 F.3d 175
    , 184 (4th Cir. 2013) (“It is well-established that parties
    cannot amend their complaint through briefing.”).

    the motion to intervene is made while the controversy is live and [2] the subsequent
    disposition of the case does not provide the relief sought by the would-be intervenors”
    and does not preclude us from granting said relief. CVLR Performance Horses, Inc. v.
    Wynne, 
    792 F.3d 469
    , 475 (4th Cir. 2015).
    Assuming arguendo that Mon Valley has satisfied the first condition for
    jurisdiction, its appeal nonetheless falters on the second condition. Mon Valley sought to
    intervene in this case to help the EPA resist Murray’s request for an injunction restricting
    the EPA’s regulatory authority under the CAA pending the agency’s compliance with
    Section 321(a). However, our holding that the EPA’s compliance with Section 321(a) is
    not judicially reviewable under Murray’s jurisdictional theories—plus our resulting
    remand for dismissal of Murray’s suit—forecloses the possibility that the district court
    could issue the above-described injunction.       Our disposition of this case therefore
    provides Mon Valley all of the relief it was seeking through intervention, and leaves us
    with no basis to entertain the organization’s appeal of the denial of its motion to
    intervene. As such, that appeal must be dismissed as moot. 6

    For the first time on appeal, Mon Valley argues that it has an interest in
    influencing the content of the evaluations that the district court ordered the EPA to
    conduct. Even if we assume that this belated argument is properly before us, it still does
    not alter our conclusion that Mon Valley’s appeal is moot. Because we are vacating the
    district court’s orders against the EPA and remanding for dismissal of Murray’s suit,
    there are no longer any valid court-ordered evaluations that we can authorize Mon Valley
    to participate in. In other words, our disposition of this case precludes us from granting
    Mon Valley the remedy that it seeks.

    IV.
    For the foregoing reasons, we vacate the district court’s judgments insofar as they
    impact the EPA, and remand with instructions to have Murray’s suit dismissed for want
    of jurisdiction. We also dismiss as moot Mon Valley’s appeal of the denial of its motion
    to intervene.
