    LOUISIANA ENVIRONMENTAL ACTION NETWORK,
    Plaintiff–Appellant
    v.
    CITY OF BATON ROUGE; PARISH OF EAST BATON ROUGE,
    Defendants–Appellees
    Appeal from the United States District Court
    for the Middle District of Louisiana
    Before KING, BENAVIDES, and DENNIS, Circuit Judges.
    PER CURIAM:
    Plaintiff–Appellant Louisiana Environmental Action Network filed this
    citizen suit against Defendants–Appellees the City of Baton Rouge and the
    Parish of East Baton Rouge, alleging violations of the Clean Water Act. The
    Defendants filed a Rule 12(b)(6) motion to dismiss, asserting that the citizen suit
    was barred under the “diligent prosecution” provision of the Act. 33 U.S.C.
    § 1365(b)(1)(B). The district court granted the motion to dismiss, but on the
    ground that the 2002 consent decree mooted Plaintiff’s claims. On appeal,
    Plaintiff contends that the district court erred in granting the Defendants’
    motion to dismiss. For the following reasons, we REVERSE the district court’s
    judgment and REMAND for further proceedings consistent with this opinion.

    I. BACKGROUND
    A. Overview of the Clean Water Act
    The Clean Water Act (“CWA” or “Act”), 33 U.S.C. § 1251 et seq., was
    enacted “to restore and maintain the chemical, physical, and biological integrity
    of the Nation’s waters.” 33 U.S.C. § 1251(a). The Act prohibits “the discharge
    of any pollutant” into navigable waters except as authorized by specified sections
    of the Act. 33 U.S.C. § 1311(a). One of these specified sections establishes the
    National Pollutant Discharge Elimination System (“NPDES”). 33 U.S.C. § 1342.
    Pursuant to this section, the Administrator of the Environmental Protection
    Agency (“EPA”) or an authorized State can issue NPDES permits, which allow
    the discharge of pollutants according to certain conditions. 
    Id. “NPDES permits
    impose limitations on the discharge of pollutants, and establish related
    monitoring and reporting requirements, in order to improve the cleanliness and
    safety of the Nation’s waters. Noncompliance with a permit constitutes a
    violation of the Act.” Friends of the Earth, Inc. v. Laidlaw Envtl. Servs. (TOC),
    Inc., 
    528 U.S. 167
    , 174 (2000) (citation omitted).
    The holder of a state NPDES permit is subject to both federal and state
    enforcement action for failure to comply with the limitations imposed in the
    permit. 33 U.S.C. §§ 1319, 1342. Furthermore, the Act contains a citizen suit
    provision, which authorizes any citizen to file a civil action to enforce an effluent
    standard in an NPDES permit, subject to certain limitations.                    33 U.S.C.
    § 1365(a), (b).1       Subsection (a) of the citizen suit provision, entitled
    “Authorization; jurisdiction,” provides that, “[e]xcept as provided in
    subsection (b) of this section . . . , any citizen may commence a civil action on his
    own behalf . . . against any person . . . who is alleged to be in violation of . . . an
    effluent standard or limitation under this chapter.” § 1365(a)(1).
    1
    The Act defines “citizen” as “a person or persons having an interest which is or may
    be adversely affected.” 33 U.S.C. § 1365(g).
    2
    Case: 11-30549    Document: 00511824872       Page: 3   Date Filed: 04/17/2012
    No. 11-30549
    However, pursuant to subsection (b) of the CWA’s citizen suit provision,
    entitled “Notice,” citizen suits are subject to two limitations. § 1365(b). First,
    sixty days before commencing a citizen suit, the citizen must give notice of the
    alleged violation to the EPA, the alleged violator, and the State in which the
    alleged violation occurs. § 1365(b)(1)(A). The Supreme Court has stated that
    “the purpose of notice to the alleged violator is to give it an opportunity to bring
    itself into complete compliance with the Act and thus . . . render unnecessary a
    citizen suit.” Gwaltney of Smithfield, Ltd. v. Chesapeake Bay Found., Inc., 
    484 U.S. 49
    , 60 (1987). Furthermore, “[t]he requirement that notice be given to the
    responsible officials highlights their primary role in enforcing the Act compared
    to the supplementary position of the citizen.” Hamker v. Diamond Shamrock
    Chem. Co., 
    756 F.2d 392
    , 396 (5th Cir. 1985).
    Second, the Act bars a citizen suit if the EPA or State “has commenced and
    is diligently prosecuting a civil or criminal action in a court of the United States,
    or a State to require compliance with the standard, limitation, or order.” 33
    U.S.C. § 1365(b)(1)(B).       “The bar on citizen suits when governmental
    enforcement action is under way suggests that the citizen suit is meant to
    supplement rather than to supplant governmental action.” 
    Gwaltney, 484 U.S. at 60
    (emphasis added). The Supreme Court noted that the “legislative history
    of the Act reinforces this view of the role of the citizen suit.” 
    Id. The Senate
    Report stated that the “Committee intends the great volume of enforcement
    actions [to] be brought by the State,” and that citizens are allowed to bring suit
    only “if the Federal, State, and local agencies fail to exercise their enforcement
    responsibility.” 
    Id. (alteration in
    original) (quoting S. REP. No. 92-414, p. 64
    (1971)). Thus, the citizens’ role in enforcing the Act is “interstitial” and should
    not be “intrusive.” 
    Id. at 61;
    see also Envtl. Conservation Org. v. City of Dallas,
    
    529 F.3d 519

    component of the CWA’s enforcement scheme, as it ‘permit[s] citizens to abate

    pollution when the government cannot or will not command compliance.’”)

    ).
    B. Statement of Facts and Proceedings
    The City of Baton Rouge (the “City”) and the Parish of East Baton Rouge
    (the “Parish”) own and operate three wastewater treatment facilities: the North,
    Central, and South Wastewater Treatment Plants. These facilities discharge
    treated sanitary wastewater into the Mississippi River. Pursuant to the Act, the
    Louisiana Department of Environmental Quality (“LDEQ”) administers a permit
    program, called the Louisiana Pollutant Discharge Elimination System
    (“LPDES”). 33 U.S.C. § 1342(b). The LDEQ issued three NPDES permits to the
    City and Parish for the discharges from the three plants. A standard condition
    in the permits, commonly known as the Eighty-Five Percent Rule, requires that
    the permit holder reduce the amount of Biochemical Oxygen Demand (“BOD”)
    and Total Suspended Solids (“TSS”) such that the thirty-day average amount
    of BOD and TSS in the wastewater discharged from the plant is at least eighty-
    five percent less than the amount of BOD and TSS in the sewage entering the
    plant. See 40 C.F.R. § 133.102.
    In March 1988, the United States filed a complaint against the City and
    the State of Louisiana alleging violations of the CWA at the North, Central, and
    South Wastewater Treatment Plants. United States v. City of Baton Rouge, et
    al., No. 3:88-cv-00191 (M.D. La.). In December 1988, the district court entered
    a consent decree to resolve those claims and to require full compliance with the
    CWA by December 31, 1996. In 1997, the district court approved a modification
    to the consent decree that provided additional time for the City to complete
    construction at the North Plant and increased stipulated penalties for violations
    of effluent limitations at that facility.
    On November 13, 2001, the United States and the State of Louisiana filed
    an enforcement action against the City and Parish, alleging that the same three
    4
    Case: 11-30549    Document: 00511824872      Page: 5    Date Filed: 04/17/2012
    No. 11-30549
    wastewater facilities violated their NPDES permits and the Act. United States
    v. City of Baton Rouge, et al., No. 3:01-cv-00978 (M.D. La.). The same day, the
    United States and the State of Louisiana lodged a proposed consent decree in the
    district court. In January 2002, the United States published notice of the
    proposed consent decree and solicited public comments in the Federal Register.
    See 67 Fed. Reg. 2669 (2002). After receiving no comments, the United States
    and the State of Louisiana filed a motion to enter the consent decree.
    On March 15, 2002, the district court entered the consent decree (the
    “2002 consent decree”), which superseded and terminated the 1988 consent
    decree. One of the objectives of the 2002 consent decree is for the City and
    Parish to “achieve and maintain compliance with [their] NPDES permits and the
    CWA.” 2002 consent decree ¶ 11(A). In order to achieve this objective, the 2002
    consent decree requires that the City and Parish implement extensive, physical
    remedial measures according to “applicable schedules.”               
    Id. ¶ 11(B).
    Additionally, the 2002 consent decree provides for “stipulated penalties” for
    certain violations of the 2002 consent decree and of the NPDES permits.
    
    Id. ¶¶ 66-83.
    With regard to effluent discharges, the 2002 consent decree
    provides for less stringent effluent limitations—a seventy-five percent reduction
    of BOD and TSS—until the City and Parish reach full completion of the remedial
    program. 
    Id. ¶ 39.
    The 2002 consent decree states that the City and Parish
    shall not be subject to penalties for failure to comply with the eighty-five percent
    reduction set out in the NPDES permits, provided that the plants comply with
    the seventy-five percent reduction set out in the 2002 consent decree. 
    Id. In 2006,
    as required by the 2002 consent decree, the City and Parish
    submitted a Second Remedial Measures Action Plan (the “Second RMAP”),
    wherein the City and Parish proposed to complete all construction and achieve
    fully operational status of its wastewater facilities by January 1, 2015. In 2007,
    the EPA and the LDEQ approved the Second RMAP. In November 2008, the
    5
    Case: 11-30549    Document: 00511824872     Page: 6   Date Filed: 04/17/2012
    No. 11-30549
    United States and the State of Louisiana lodged a proposed modification to the
    2002 consent decree, which would allow for various changes to the Second RMAP
    but would not alter the January 2015 compliance deadline. The United States
    published a notice of the proposed modification in the Federal Register and
    solicited public comments. See 73 Fed. Reg. 67882 (2008). In April 2009, the
    district court approved the modification of the 2002 consent decree.
    The Louisiana Environmental Action Network (“LEAN”) is a non-profit
    community organization incorporated and operating under the laws of
    Louisiana. LEAN describes itself as “an umbrella organization for several
    environmental and citizen groups in Louisiana . . . . LEAN has more than 1,700
    individual members, some of whom reside, own property, work, and recreate in
    areas near and downstream of [the City and Parish’s] plants . . . . LEAN’s
    purpose is to preserve and protect Louisiana’s land, air, water, and other natural
    resources.” LEAN’s members “complain[ed] that untreated wastewater and raw
    sewerage are being discharged onto their properties,” and LEAN became
    concerned about “sanitary sewer overflows occurring in association with the
    [three] plants.”    Also, LEAN analyzed the City and Parish’s Discharge
    Monitoring Reports, which indicated that there are ongoing violations at the
    three plants of the Eighty-Five Percent Rule and of the 2002 consent decree’s
    seventy-five percent reduction requirement.
    On November 24, 2009, LEAN sent a Notice of Violation to the City and
    Parish, the EPA, and the LDEQ pursuant to the Act. 33 U.S.C. § 1365(b)(1)(A).
    LEAN sent a revised notice to the same entities on December 21, 2009. In the
    revised notice, LEAN alleged that the North, Central, and South Wastewater
    Treatment Plants are in violation of the CWA for failing to meet the effluent
    standards set out in the NPDES permits. Additionally, LEAN alleged that “the
    plants have failed to even meet the relaxed effluent limitations set forth in the
    [2002] consent decree.”
    6
    Case: 11-30549   Document: 00511824872      Page: 7   Date Filed: 04/17/2012
    No. 11-30549
    After providing sixty-days’ notice, LEAN filed this citizen suit against the
    City and Parish (collectively, the “Defendants”) in the United States District
    Court for the Middle District of Louisiana on March 22, 2010. In its amended
    complaint, LEAN alleged that it had met its notice obligations, stating that
    “[n]either EPA nor LDEQ has commenced or is diligently prosecuting a civil or
    criminal action in court to redress the violations specified in the Notice and
    Revised Notice.” LEAN asserted two causes of action against the Defendants.
    First, LEAN alleged that the three wastewater treatment plants violate both the
    eight-five percent reduction requirement in the three NPDES permits and the
    seventy-five percent reduction requirement in the 2002 consent decree. Second,
    LEAN alleged that the Defendants are in violation of their permits by failing to
    “properly operate and maintain all facilities and systems of treatment and
    control . . . which are installed or used by the permittee to achieve compliance.”
    LEAN sought a declaration that the Defendants are in violation of the CWA and
    the three permits; an injunction compelling the Defendants’ compliance with the
    permits; an award of civil penalties payable to the U.S. Treasury; attorney’s fees
    and litigation expenses; and any other relief the court deems appropriate.
    On June 3, 2010, the Defendants filed a motion to dismiss LEAN’s suit
    pursuant to Federal Rule of Civil Procedure 12(b)(6). The Defendants argued
    that LEAN’s citizen suit was barred under the “diligent prosecution” provision
    of the CWA. 33 U.S.C. § 1365(b)(1)(B). The Defendants stated that they are still
    subject to the 2002 consent decree, which allows the Defendants to come into
    compliance with the CWA by January 1, 2015. The Defendants contended that
    both of LEAN’s claims “pertain to violations that require compliance with the
    same standards” that are the subject of the 2002 consent decree.             The
    Defendants argued that, given the EPA’s ongoing enforcement of the 2002
    consent decree, LEAN’s citizen suit is precluded by the Act and should be
    7
    Case: 11-30549   Document: 00511824872       Page: 8   Date Filed: 04/17/2012
    No. 11-30549
    dismissed. The Defendants asserted that “allowing LEAN to maintain this
    citizen suit undermines the [CWA’s] enforcement scheme.”
    In its opposition to the Defendants’ motion to dismiss, LEAN responded
    that the “mere existence of an 8-yr old consent decree—in an administratively
    closed case—does not establish diligent prosecution.” LEAN argued that the
    Defendants cannot immunize themselves from liability for violations of the CWA
    by relying on the 2002 consent decree. After the Defendants filed a reply to
    LEAN’s opposition and LEAN filed a sur-reply, the district court held oral
    argument on the Defendants’ motion to dismiss on March 16, 2011.
    The district court granted the Defendants’ Rule 12(b)(6) motion to dismiss.
    In its order (the “Order”), the court first discussed the Defendants’ argument
    that the “diligent prosecution” provision of the Act bars LEAN’s citizen suit. 33
    U.S.C. § 1365(b)(1)(B). The court discussed Supreme Court and circuit court
    caselaw regarding the citizen suit provision of the CWA and the “diligent
    prosecution” bar. The court stated that “[t]he Act strips courts of subject matter
    jurisdiction over citizen suits once the EPA has timely commenced judicial or
    administrative enforcement actions.”        However, the court did not rule on
    whether LEAN’s suit is barred under § 1365(b)(1)(B).
    Instead, the district court analyzed whether LEAN’s claims were rendered
    moot by the 2002 consent decree.         The court relied on our decision in
    Environmental Conservation Organization v. City of Dallas, 
    529 F.3d 519
    (5th
    Cir. 2008), explaining that we held that “a consent decree properly entered into
    by the EPA and the City of Dallas to address alleged violations of the Clean
    Water Act mooted a pre-existing citizen suit filed subsequently for the same
    purposes.” The court recognized that the City of Dallas case was “not exactly
    analogous”—as the City of Dallas citizen suit was filed prior to the entry of the
    consent decree whereas, in the present case, LEAN’s citizen suit was filed after
    the entry of the 2002 consent decree. Despite this difference, the court applied
    8
    Case: 11-30549   Document: 00511824872      Page: 9   Date Filed: 04/17/2012
    No. 11-30549
    the mootness standard enunciated in City of Dallas, which is that “the party
    denying mootness must show that there is a realistic prospect that the alleged
    violations will continue despite the [existence of the consent decree.]”
    The court noted that the Defendants stated in their pleadings and at oral
    argument that “they are in full compliance with the 2002 consent decree, and are
    on schedule to complete massive updates and improvements to the three
    wastewater treatment plants by January, 2015 (in accordance with the 2002
    consent decree).” The court held that the Defendants’ compliance with the 2002
    consent decree addresses LEAN’s grievances, thereby rendering LEAN’s claims
    moot. The court stated that “[p]rior to the January 2015 compliance deadline set
    by the 2002 consent decree, no remedy is available to [LEAN] absent a finding
    of non-compliance by the Court having proper jurisdiction to enforce the decree.”
    The court explained that if LEAN “is correct in its assertion that Defendants are
    not complying with the 2002 consent decree, the Court encourages [LEAN] to
    take up the matter . . . with the EPA, as the EPA has the power to enforce the
    consent decree.” LEAN timely appealed the district court’s judgment.
    II. DISCUSSION
    A. The District Court Erred in Dismissing LEAN’s Action as Moot
    Although the district court granted the Defendants’ Rule 12(b)(6) motion
    to dismiss for failure to state a claim, the court reasoned that LEAN’s action
    must be dismissed based on mootness. In the Order, the court explained that
    LEAN’s claims were rendered moot by the Defendants’ ongoing compliance with
    the 2002 consent decree. Thus, the district court’s dismissal of LEAN’s action
    was based on a lack of federal jurisdiction. See City of 
    Dallas, 529 F.3d at 524
    (stating that a mootness argument raises a question of federal jurisdiction). We
    have stated that “we are not bound by the label the district court puts on its
    action where underlying facts indicate that a different action was in fact
    intended.” Williamson v. Tucker, 
    645 F.2d 404
    , 412 (5th Cir. 1981) (citation
    9
    Case: 11-30549       Document: 00511824872         Page: 10     Date Filed: 04/17/2012
    No. 11-30549
    omitted). Therefore, based on the district court’s reasoning, we construe its
    dismissal of LEAN’s suit as a dismissal for lack of jurisdiction, not for failure to
    state a claim. See 
    id. “We review
    questions of federal jurisdiction de novo, including arguments
    that a case or controversy has become moot.” City of 
    Dallas, 529 F.3d at 524
    (citation omitted). “Mootness is the doctrine of standing in a time frame. The
    requisite personal interest that must exist at the commencement of litigation
    (standing) must continue throughout its existence (mootness).” 
    Id. at 524-25
    (citations and internal quotation marks omitted). “If a case has been rendered
    moot, a federal court has no constitutional authority to resolve the issues that
    it presents.” 
    Id. at 525
    (citation omitted).
    In City of Dallas, we held that, where the entry of a consent decree
    occurred after the filing of a CWA citizen suit, the citizen suit is rendered moot
    unless the citizen-suit plaintiff “proves that there is a realistic prospect that the
    violations alleged in its complaint will continue notwithstanding the consent
    decree.” 
    Id. at 528
    (citations omitted). In the present case, the district court
    applied the City of Dallas mootness standard to LEAN’s action, despite the fact
    that LEAN’s citizen suit was filed years after the entry of the 2002 consent
    decree. In applying the standard, the court found that LEAN could not meet the
    “reasonable prospect” test because the Defendants had asserted that they are in
    compliance with the conditions of the 2002 consent decree. Thus, the district
    court held that the 2002 consent decree rendered LEAN’s citizen suit moot.
    We hold that the district court erred in applying the City of Dallas
    mootness standard to the present case.2 In City of Dallas, we “recognized that
    2
    Environment America (“EA”), “a federation of [twenty-nine] non-profit, non-partisan,
    state-based environmental advocacy organizations with a longstanding interest in the vigorous
    and effective enforcement of the Clean Water Act,” filed an amicus curiae brief in support of
    LEAN. EA asserts that the district court should not have conducted a mootness analysis,
    because the 2002 consent decree was entered prior to the filing of LEAN’s suit.
    10
    Case: 11-30549     Document: 00511824872     Page: 11   Date Filed: 04/17/2012
    No. 11-30549
    developments subsequent to the filing of a citizen suit may moot the citizen’s
    
    case.” 529 F.3d at 526
    (emphasis added) (citation omitted). We stated that, “[a]s
    a general rule, any set of circumstances that eliminates actual controversy after
    the commencement of a lawsuit renders that action moot.” 
    Id. at 527
    (emphasis
    added) (citation and internal quotation marks omitted). In City of Dallas, the
    plaintiff filed its citizen suit prior to the entry of a consent decree between the
    defendant and the United States and the State of Texas. Thus, it was proper for
    the court to examine whether the subsequent development of the consent decree
    mooted the plaintiff’s properly-filed citizen suit.
    In the instant case, however, LEAN filed its citizen suit approximately
    eight years after the entry of the 2002 consent decree between the Defendants
    and the United States and the State of Louisiana. Neither party argues that any
    circumstances subsequent to the filing of LEAN’s lawsuit have rendered LEAN’s
    citizen suit moot. Thus, the district court erred in examining whether the 2002
    consent decree, and the ongoing enforcement of its conditions, mooted LEAN’s
    citizen suit. See 13B WRIGHT & MILLER, FEDERAL PRACTICE          AND   PROCEDURE
    § 3533 (3d ed.) (“Mootness doctrine encompasses the circumstances that destroy
    the justiciability of a suit previously suitable for determination.”) (emphasis
    added). Therefore, the district court improperly dismissed LEAN’s citizen suit
    based on mootness.
    B. The “Diligent Prosecution” Bar
    Having determined that the dismissal of LEAN’s action was not warranted
    on mootness grounds, we now turn to the alternate ground not resolved by the
    district court—whether LEAN’s citizen suit is precluded under the CWA’s
    “diligent prosecution” provision. 33 U.S.C. § 1365(b)(1)(B).
    On appeal, the Defendants assert that “[t]he diligent prosecution bar to
    this citizen suit is the controlling and deciding issue” and that we “may affirm
    the district court ruling on that issue alone.” The Defendants contend that the
    11
    Case: 11-30549     Document: 00511824872       Page: 12    Date Filed: 04/17/2012
    No. 11-30549
    “diligent prosecution” bar is jurisdictional and therefore strips the district court
    of subject matter jurisdiction to hear the case. LEAN, however, contends that
    the “diligent prosecution” bar is not jurisdictional. Therefore, LEAN asserts that
    the bar does not preclude its citizen suit, because the district court was obligated
    to give it “an opportunity to prove its well-pled allegations that there is no
    diligent prosecution.”
    We must decide an issue of first impression in this circuit—whether the
    CWA’s “diligent prosecution” bar is jurisdictional. This issue has important
    practical implications for the court and parties in this case. If the provision is
    not jurisdictional, then LEAN is protected by the safeguards of Federal Rule of
    Civil Procedure 12(b)(6)—the district court is required to accept all well-pleaded
    facts in LEAN’s complaint as true and view the facts in the light most favorable
    to LEAN. See Lone Star Fund V (U.S.), L.P. v. Barclays Bank PLC, 
    594 F.3d 383
    , 387 (5th Cir. 2010) (“The ultimate question in a Rule 12(b)(6) motion is
    whether the complaint states a valid claim when all well-pleaded facts are
    assumed true and are viewed in the light most favorable to the plaintiff.”)
    (citation omitted). However, if the provision is jurisdictional, and thus goes to
    the district court’s subject matter jurisdiction, then the district court is not
    obligated to accept the assertions in LEAN’s complaint as true. Instead, the
    district court is empowered “to make factual findings which are decisive of
    jurisdiction,” because “[j]urisdictional issues are for the court . . . to decide.”
    
    Williamson, 645 F.2d at 413
    (citations omitted). With this understanding of the
    important practical consequences in mind, we turn to recent Supreme Court
    cases that provide guidance on determining whether a provision is jurisdictional.
    The Supreme Court “has endeavored in recent years to ‘bring some
    discipline’ to the use of the term ‘jurisdictional.’” Gonzalez v. Thaler, 
    132 S. Ct. 641

    Ct. 584 (2009); Arbaugh v. Y & H Corp., 
    546 U.S. 500
    (2006); Kontrick v. Ryan,
    
    540 U.S. 443
    (2004). The Court has stated 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 . . . should not be given the jurisdictional brand.” Henderson, 131 S.
    Ct. at 1202-03 (citations omitted). “Among the types of rules that should not be
    described as jurisdictional are . . . ‘claim-processing rules,’” which are “rules that
    seek to promote the orderly progress of litigation by requiring that the parties
    take certain procedural steps at certain specified times.” 
    Id. at 1203
    (citations
    omitted); see also 
    Kontrick, 540 U.S. at 455
    (“Clarity would be facilitated if courts
    and litigants used the label ‘jurisdictional’ not for claim-processing rules, but
    only for prescriptions delineating the classes of cases (subject-matter
    jurisdiction) and the persons (personal jurisdiction) falling within a court’s
    adjudicatory authority.”).
    The Court has acknowledged that “the distinction between jurisdictional
    conditions and claim-processing rules can be confusing in practice.” Reed
    Elsevier, 
    Inc., 130 S. Ct. at 1234
    . Many courts have “mischaracterized claim-
    processing rules or elements of a cause of action as jurisdictional limitations,
    particularly when that characterization was not central to the case, and thus did
    not require close analysis.” 
    Id. at 1234-44
    (citations omitted). The Court’s cases
    “evince a marked desire to curtail such ‘drive-by jurisdictional rulings,’ which too
    easily can miss the ‘critical difference[s]’ between true jurisdictional conditions
    and nonjurisdictional limitations on causes of action.” 
    Id. at 1244
    (alteration in
    original) (citations omitted). Such “‘drive-by jurisdictional rulings’ . . . should be

    accorded ‘no precedential effect’ on the question whether the federal court had
    authority to adjudicate the claim.” 
    Arbaugh, 546 U.S. at 511
    (citation omitted).3
    The Supreme Court has emphasized that courts should not attach the
    “jurisdictional” label lightly, because of the important practical—and sometimes
    “drastic”—consequences that may flow from the label. See 
    Henderson, 131 S. Ct. at 1202
    (“Th[e] question [of whether a provision is “jurisdictional”] is not merely
    semantic but one of considerable practical importance for judges and litigants.”);
    see also 
    Gonzalez, 132 S. Ct. at 648
    (“Courts . . . should not lightly attach those
    ‘drastic’ consequences to limits Congress has enacted.”).                  The Court has
    explained that “[b]randing a rule as going to a court’s subject-matter jurisdiction
    alters the normal operation of our adversarial system.” 
    Henderson, 131 S. Ct. at 1202
    . For instance, “[w]hen a requirement goes to subject-matter jurisdiction,
    courts are obligated to consider sua sponte issues that the parties have
    disclaimed or have not presented.” 
    Gonzalez, 132 S. Ct. at 648
    (citation
    omitted). Additionally, “[o]bjections to subject-matter jurisdiction . . . may be
    raised at any time,” such as after trial, which can result in the waste of “many
    months of work on the part of attorneys and the court.” 
    Henderson, 131 S. Ct. at 1202
    . Furthermore, “if subject-matter jurisdiction turns on contested facts,

    With regard to the CWA’s “diligent prosecution” provision, several courts have stated
    in passing that the provision is jurisdictional. See, e.g., Chesapeake Bay Found. v. Am.
    Recovery Co., 
    769 F.2d 207
    , 208 (4th Cir. 1985) (noting that the “diligent prosecution” bar is
    “an exception to the jurisdiction granted in subsection (a) of § 1365”); Friends of Milwaukee’s
    Rivers v. Milwaukee Metro. Sewerage Dist., 
    556 F.3d 603
    , 606 (7th Cir. 2009) (stating that the
    CWA “strips the courts of subject matter jurisdiction over citizens’ suits where the State [or
    EPA] has timely commenced judicial or administrative enforcement actions” under
    § 1365(b)(1)(B)). These statements are aptly classified as “drive-by jurisdictional rulings”
    because the courts did not attempt to distinguish “between true jurisdictional conditions and
    nonjurisdictional limitations on causes of action.” Reed Elsevier, 
    Inc., 130 S. Ct. at 1244
    (citations and internal quotation marks omitted). Therefore, these statements are afforded
    “no precedential effect” on whether the “diligent prosecution” bar is jurisdictional. 
    Arbaugh, 546 U.S. at 511
    (citation and internal quotation marks omitted).

    the trial judge may be authorized to review the evidence and resolve the dispute
    on her own.” 
    Arbaugh, 546 U.S. at 514
    (citations omitted).
    Given the important differences between jurisdictional provisions and
    claim-processing rules, the Supreme Court has provided guidance to the lower
    courts on the proper analysis to use to determine if a statutory provision is
    jurisdictional. In Arbaugh v. Y & H Corp., 
    546 U.S. 500
    (2006), the Court
    enunciated the following “readily administrable bright line” rule: A provision is
    jurisdictional “[i]f the Legislature clearly states that a threshold limitation on a
    statute’s scope shall count as jurisdictional.” 
    Id. at 515-16
    (emphasis added).
    However, “when Congress does not rank a statutory limitation on coverage as
    jurisdictional, courts should treat the restriction as nonjurisdictional in
    character.” 
    Id. at 516.
    Additionally, in Reed Elsevier, Inc. v. Muchnick, 130 S.
    Ct. 1237 (2010), the Court elaborated that “context, including [the Supreme]
    Court’s interpretation of similar provisions in many years past, is relevant to
    whether a statute ranks a requirement as jurisdictional.” 
    Id. at 1248.
    The
    Court stated that “the jurisdictional analysis must focus on the ‘legal character’
    of the requirement, which [is] discerned by looking to the condition’s text,
    context, and relevant historical treatment.” 
    Id. at 1246
    (citations omitted).
    Ultimately, the question is whether Congress mandated that the particular
    provision be “jurisdictional.” See 
    Henderson, 131 S. Ct. at 1203
    . The Court’s
    clear statement approach “is suited to capture Congress’ likely intent and also
    provides helpful guidance for courts and litigants.” 
    Id. (citation omitted).
          Applying these principles to the present case, we conclude that Congress
    has not clearly mandated that the CWA’s “diligent prosecution” provision is
    jurisdictional. We first analyze the text of this particular provision to determine
    whether the provision “was meant to carry jurisdictional consequences.”
    
    Henderson, 131 S. Ct. at 1204
    . Section 1365(b)(1)(B) provides:
    15
    Case: 11-30549    Document: 00511824872       Page: 16   Date Filed: 04/17/2012
    No. 11-30549
    (b) Notice
    No action may be commenced–
    (1) under subsection (a)(1) of this section–
    (B) if the Administrator or State has commenced and is
    diligently prosecuting a civil or criminal action in a
    court of the United States, or a State to require
    compliance with the standard, limitation, or order, but
    in any such action in a court of the United States any
    citizen may intervene as a matter of right.
    The language of § 1365(b)(1)(B) does not “clearly state[]” that the “diligent
    prosecution” bar is jurisdictional. 
    Arbaugh, 546 U.S. at 515
    . This provision
    “does not speak in jurisdictional terms or refer in any way to the jurisdiction of
    the district courts.” Zipes v. Trans World Airlines, Inc., 
    455 U.S. 385
    , 394 (1982).
    Although it is true that § 1365(b)(1)(B) is phrased in mandatory language, the
    Supreme Court has “rejected the notion that ‘all mandatory prescriptions,
    however emphatic, are . . . properly typed jurisdictional.’” 
    Henderson, 131 S. Ct. at 1205
    (alteration in original) (citation omitted).       Thus, the language of
    § 1365(b)(1)(B) does not provide a clear indication that Congress intended the
    provision to be jurisdictional.
    The placement of the “diligent prosecution” provision within the CWA also
    does not indicate that Congress “wanted [the] provision to be treated as having
    jurisdictional attributes.” 
    Id. at 1205.
    Congress placed § 1365(b)(1)(B) in the
    “Notice” section of the CWA citizen suit provision. See 
    id. (“[T]he title
    of a
    statute or section can aid in resolving an ambiguity in the legislation’s text.”)
    (alteration in original) (citation and internal quotation marks omitted). The
    “Notice” section also includes the requirement that a citizen provide notice of the
    alleged violation to the alleged violator, the State, and the EPA sixty-days prior
    to filing a citizen suit. See 33 U.S.C. § 1365(b)(1)(A). The sixty-day notice
    provision is a typical “claim-processing rule.” See 
    Henderson, 131 S. Ct. at 1203
    ;
    
    Zipes, 455 U.S. at 398

    timely file a discrimination charge with the EEOC before filing an action in

    Case: 11-30549       Document: 00511824872           Page: 17      Date Filed: 04/17/2012
    No. 11-30549
    federal court is nonjurisdictional). The placement of the “diligent prosecution”
    bar in the “Notice” section, alongside a typical claim-processing rule, suggests
    that Congress intended the “diligent prosecution” bar to be a claim-processing
    rule. See 
    Henderson, 131 S. Ct. at 1205
    (finding that the placement of a
    provision in a subchapter entitled “Procedure” indicated that “Congress regarded
    the 120-day limit as a claim-processing rule”).
    Furthermore, the “diligent prosecution” provision is “located in a provision
    ‘separate’ from those granting federal courts subject-matter jurisdiction
    over . . . [the] claims.” Reed Elsevier, 
    Inc., 130 S. Ct. at 1245-46
    (citation
    omitted). The district courts have subject matter jurisdiction over CWA citizen
    suits pursuant to the general federal question jurisdiction statute, 28 U.S.C.
    § 1331,4 and the CWA’s jurisdictional provision, 33 U.S.C. § 1365(a).5 Neither
    of these provisions specifies any threshold requirement for subject matter
    jurisdiction, let alone ties its jurisdictional grant to the issue of diligent
    prosecution. See 
    Arbaugh, 546 U.S. at 515
    (“But neither § 1331, nor Title VII’s
    jurisdictional provision, 42 U.S.C. § 2000e–5(f)(3) . . . specifies any threshold
    ingredient akin to 28 U.S.C. § 1332’s monetary floor.”); see also Reed Elsevier,
    
    Inc., 130 S. Ct. at 1246
    (“[N]either § 1331, . . . nor § 1338(a), which is specific to
    copyright claims, conditions its jurisdictional grant on whether copyright holders
    have registered their works before suing for infringement.”).                      Instead, the
    “diligent prosecution” bar is located in a separate provision of the CWA that does
    not pertain or refer to jurisdiction. See 
    Arbaugh, 546 U.S. at 515
    -16 (holding

    Section 1331 provides that “[t]he district courts shall have original jurisdiction of all
    civil actions arising under the Constitution, laws, or treaties of the United States.” 28 U.S.C.
    § 1331.
    5
    The CWA’s jurisdiction-conferring provision, located in the final paragraph of
    subsection (a), states that “[t]he district courts shall have jurisdiction, without regard to the
    amount in controversy or the citizenship of the parties, to enforce such an effluent standard
    or limitation . . . .” 33 U.S.C. § 1365(a).

    that Title VII’s employee-numerosity requirement is nonjurisdictional because
    it is located in a provision separate from those granting courts subject matter
    jurisdiction and the provision does not speak in jurisdictional terms); see also
    Reed Elsevier, 
    Inc., 130 S. Ct. at 1245-46
    (holding that the Copyright Act’s
    registration requirement is not jurisdictional primarily because it is located in
    a provision separate from those granting the courts subject matter jurisdiction
    and the provision does not “clearly state[]” that the requirement is
    jurisdictional). Thus, § 1365(b)(1)(B)’s location in a provision separate from the
    jurisdiction-granting provisions indicates that Congress did not intend the
    provision to be jurisdictional.
    The “historical treatment” factor also does not indicate that the provision
    ranks as jurisdictional. Reed Elsevier, 
    Inc., 130 S. Ct. at 1246
    . No Supreme
    Court cases have determined that the “diligent prosecution” provision of the
    CWA, or any similar provision in other environmental statutes, is jurisdictional.
    “There is thus no ‘long line of [Supreme] Court[] decisions left undisturbed by
    Congress’ on which to rely.” 
    Gonzalez, 132 S. Ct. at 648
    n.3 (citation omitted);
    see 
    Henderson, 131 S. Ct. at 1203
    (“When a long line of [Supreme] Court[]
    decisions left undisturbed by Congress has treated a similar requirement as
    jurisdictional, we will presume that Congress intended to follow that course.”)
    (citations and internal quotation marks omitted).
    Based on the foregoing analysis, we conclude that Congress has not
    provided a clear statement that the “diligent prosecution” bar is jurisdictional.
    Absent such a clear statement from Congress, we hold that the “diligent
    prosecution” bar is a nonjurisdictional limitation on citizen suits. See 
    Arbaugh, 546 U.S. at 516
    (“[W]hen Congress does not rank a statutory limitation on
    coverage as jurisdictional, courts should treat the restriction as nonjurisdictional
    in character.”).

    No. 11-30549
    Our conclusion that the CWA’s “diligent prosecution” provision is
    nonjurisdictional is buttressed by the Seventh Circuit’s recent decision in Adkins
    v. VIM Recycling, Inc., 
    644 F.3d 483
    (7th Cir. 2011). There, the court held that
    the “diligent prosecution” provision of the Resource Conservation and Recovery
    Act (“RCRA”)—which is virtually identical to the “diligent prosecution” provision
    of the CWA6—is not jurisdictional. 
    Id. at 492.
    Applying the guiding principles
    of the recent Supreme Court cases, the Seventh Circuit concluded that, because
    “RCRA’s limits on citizen suits appear in separate provisions that do not ‘speak
    in jurisdictional terms,’” the RCRA “diligent prosecution” bar is a
    nonjurisdictional claim-processing rule. 
    Id. (citations omitted).
          Having determined that the CWA’s “diligent prosecution” bar is not
    jurisdictional, the question still remains whether the “diligent prosecution”
    provision precludes LEAN’s action in the present case. The Defendants assert
    that the EPA’s continued enforcement of the 2002 consent decree constitutes
    diligent prosecution. Indeed, the Defendants point to the extensive remedial
    measures they are undertaking, as required by the 2002 consent decree, which
    are projected to cost the Defendants over $1 billion. The Defendants contend
    that LEAN’s “lawsuit stands as an impediment” to their efforts to achieve
    compliance with the CWA.          However, LEAN asserts that the EPA is not
    diligently prosecuting the 2002 consent decree, noting the plants’ ongoing, non-
    compliant discharges and the EPA’s failure to impose stipulated penalties for
    these violations. LEAN argues that the issue of “diligent prosecution” is a fact-
    intensive question that can only be answered after the proper development of a
    record. We take no position on these arguments. We think it wise for the
    district court to determine in the first instance whether LEAN’s suit is precluded

    493 U.S. 20
    , 23 (1989) (noting that the notice
    provisions of the RCRA and the CWA, like those of many other environmental statutes, were
    “modeled upon § 304 of the Clean Air Amendments of 1970”).

    For the foregoing reasons, we REVERSE the judgment of the district court
    and REMAND for further proceedings consistent with this opinion.
