    OPINION
    _________________
    KAREN NELSON MOORE, Circuit Judge. Three environmental organizations brought this
    suit under the Clean Air Act’s citizen-suit provisions, alleging that the Tennessee Valley Authority
    (“TVA”) shirked its duty to obtain appropriate pollution limitations at a power plant it operates in
    Clinton, Tennessee. The district court granted summary judgment to TVA, concluding that the
    statute of limitations had run on the plaintiffs’ claim for statutory penalties and that the concurrent-
    remedy rule barred their claim for injunctive relief. We conclude that the district court’s ruling on
    the statute of limitations was in error, REVERSE its grant of summary judgment, and REMAND
    this case for further proceedings consistent with this opinion.
    I. BACKGROUND
    A. Regulatory Framework
    The primary purpose of the Clean Air Act (“CAA”) is “to protect and enhance the quality
    of the Nation’s air resources so as to promote the public health and welfare and the productive
    capacity of its population.” 
    42 U.S.C. § 7401
    (b)(1). To achieve these goals, Congress instructed
    the United States Environmental Protection Agency (“EPA”) to develop limits on the maximum
    concentrations of various pollutants allowable in different areas of the country, known as National
    Ambient Air Quality Standards (“NAAQS”). 
    Id.
     § 7409. To enforce these limits, the CAA employs
    a system of cooperative federalism, requiring states to create plans “provid[ing] for implementation,
    maintenance, and enhancement” of the NAAQS. Id. § 7410(a)(1). Such a plan, called a “state
    implementation plan” (“SIP”), must:
    ! include enforceable emissions limitations and control measures, as well as
    compliance schedules, id. § 7410(a)(2)(A);
    ! provide for monitoring and analysis of air quality, id. § 7410(a)(2)(B);
    ! include an enforcement program, id. § 7410(a)(2)(C);
    ! regulate the construction and modification of sources of pollution, id.;
    ! prohibit emissions that will harm other states’ efforts toward reducing air
    pollution, id. § 7410(a)(2)(D)(i);
    ! assure proper funding, staffing, and legal authority to carry out the SIP, id.
    § 7410(a)(2)(E); and
    ! require polluters to monitor the output of pollution and report the results to the
    state, id. § 7410(a)(2)(F).
    After several years under this regulatory regime, Congress recognized that merely setting
    ceilings on emissions did not discourage existing polluters from increasing their pollution levels up
    to these limits, or encourage new polluters to minimize their emissions. To fix this defect, Congress
    amended the CAA in 1977 to include the “New Source Review” program. United States v. Duke
    Energy Corp., 
    278 F. Supp. 2d 619
    , 628 (M.D.N.C. 2003), aff’d, 
    411 F.3d 539
     (4th Cir. 2005), cert.
    granted sub nom. Envtl. Def. v. Duke Energy Corp., 
    126 S. Ct. 2019
     (2006). New Source Review
    featured “provisions for the protection of areas with relatively clean air [known as] Prevention of
    Significant Deterioration,” or “PSD.” Duke Energy, 
    278 F. Supp. 2d at 628
    .
    No. 05-6329               Nat’l Parks Conservation Assoc. et al. v. TVA                                       Page 3
    Under PSD, each SIP must “contain emission limitations and such other measures as may
    be necessary . . . to prevent significant deterioration of air quality”1 by new sources of pollution or
    old sources that have undergone modifications. 
    42 U.S.C. § 7471
    . Because a key purpose of PSD
    is “to assure that any decision to permit increased air pollution . . . is made only after careful
    evaluation of all the consequences of such a decision,” 
    id.
     § 7470(5), polluters “are required to limit
    emissions to a ‘baseline rate’ and [to] obtain a permit before constructing or modifying facilities.”
    Duke Energy, 278 F. Supp. at 628 (emphasis in original). These permits are often referred to as
    “PSD permits,” and they must both “set[] forth emission limitations for such facility,” 
    42 U.S.C. § 7475
    (a)(1), and require that any proposed facility must be “subject to the best available control2
    technology for each pollutant . . . emitted from, or which results from” the facility, 
    id.
     § 7475(a)(4).
    Additionally, PSD permits require the owner or operator of the plant to agree to ongoing monitoring
    “to determine the effect which emissions from any such facility may have, or is [sic] having, on air
    quality” in affected areas. Id. § 7475(a)(7).
    Tennessee’s SIP provides for separate permits for construction and operation of sources of
    air pollution, compare TENN. COMP. R. & REGS. § 1200-3-9-.01 with id. § 1200-3-9-.02, but
    prohibits the issuance of an operating permit until all requirements of the construction permit are
    met, id. § 1200-3-9-.01(1)(e). Tennessee’s construction-permit regulations prohibit the
    commencement of “modification of an air contaminant source . . . without [the operator’s] first
    having applied for and received . . . a construction permit for the construction or modification of
    such air contaminant source.” Id. § 1200-3-9-.01(1)(a). In turn, any construction or modification
    must comply with the emissions limitations expressed in “the approved construction permit
    application,” and also with “all provisions of the regulations of [the Tennessee SIP], any applicable
    measures of the control strategy, and all provisions of the Tennessee Air Quality Act.” Id. § 1200-3-
    9-.01(1)(d). Plants must also operate in accordance with the limits expressed in construction permits
    because, as the deputy director of the Tennessee Air Pollution Control Division explained in
    deposition, the limitations included in construction permits are carried into operating permits, which
    contain no independent emissions limitations themselves. Joint Appendix (“J.A.”) at 625-26, 632
    (Styke Depo. at 90-93, 119).
    The construction permitting requirements of Tennessee’s SIP also provide:
    In the case where a source or modification was constructed without first obtaining
    a construction permit, a construction permit may be issued to the source or
    modification to establish as conditions of the permit, the necessary emission limits
    and requirements to assure that these regulatory requirements are met. The
    appropriate enforcement action shall be pursued to insure that ambient air quality
    standards and other regulatory requirements will be met.
    TENN. COMP. R. & REGS. § 1200-3-9-.01(1)(e). This provision places upon polluters an ongoing
    duty to ensure that they obtain the appropriate emissions limitations in their construction permits,
    even if they failed to do so before construction. These limitations include Best Available Control
    Technology (“BACT”), id. § 1200-3-9-.01(4)(j), and other limitations flowing from the SIP’s PSD
    provisions, see id. § 1200-3-9-.01(4).
    1
    The PSD program applies only to regions that the EPA classifies as being in “attainment” of NAAQS or as
    “unclassifiable.” 
    42 U.S.C. § 7471
    . More stringent requirements apply to areas designated as being in “nonattainment”
    of NAAQS under 
    42 U.S.C. § 7407
    (d)(1)(A)(iii).
    2
    Best available control technology, commonly referred to as “BACT,” is not actually technology; instead, it
    is “an emission limitation based on the maximum degree of reduction” possible, taking into account a number of factors.
    
    42 U.S.C. § 7479
    (3).
    No. 05-6329           Nat’l Parks Conservation Assoc. et al. v. TVA                           Page 4
    The Tennessee SIP’s PSD program, however, does not apply to all modifications of
    emissions sources. Instead, the PSD regulations — a subset of the generally applicable construction
    regulations described above — apply only to new construction and to “major modifications” that
    would produce “a significant net emissions increase” of a pollutant. 
    Id.
     § 1200-3-9-.01(4)(a)(1)-(2).
    Similar to the general construction regulations, the PSD program employs a permitting process that
    forbids any owner or operator to commence construction without the necessary approvals or to
    “construct[] or operate[] a source or modification” inconsistently with the applicable PSD permit.
    Id. § 1200-3-9-.01(4)(a)(3). And like the general construction regulations, the emissions limitations
    established in a PSD permit determine the emissions limitations in an operating permit. As the
    Tennessee Air Pollution Control Division’s deputy director put it, “The PSD permit establishes an
    initial limit which would be carried over to a separate operating permit and subsequent operating
    permits until such time that a recision [of the PSD permit] occurred.” J.A. at 635 (Styke Depo. at
    131). Further, Tennessee’s PSD program requires that subject sources “shall apply best available
    control technology” and “shall meet each applicable emissions limitation under . . . the State
    Implementation Plan.” TENN. COMP. R. & REGS. § 1200-3-9-.01(4)(j).
    B. Relevant Factual Background
    TVA, a corporation created by statute with a board of directors appointed by the President,
    
    16 U.S.C. §§ 831
    -831a, owns and operates the Bull Run power plant in Clinton, Tennessee. In
    1988, TVA performed a “major overhaul” of the boiler used to produce electricity, in which it
    replaced approximately 58,000 feet of tubing inside the boiler. Joint Appendix (“J.A.”) at 644-45.
    This quantity amounts to about 26.5% of the total tubing inside the boiler. TVA admits that it never
    applied for, or obtained, a PSD permit under the Tennessee SIP’s PSD regulations, and does not
    indicate whether it applied for any other permit before the project.
    Following an investigation, in November 1999, the EPA issued an administrative compliance
    order (“ACO”) concluding that the boiler overhaul at Bull Run constituted a modification of the
    plant, and therefore triggered the PSD provisions of the Tennessee SIP. TVA v. Whitman, 
    336 F.3d 1236
    , 1244 (11th Cir. 2003), cert. denied, 
    541 U.S. 1030
     (2004). The ACO further required TVA
    to obtain all required permits and enter into a compliance agreement with the EPA. 
    Id.
    After extensive negotiations between TVA and the EPA and various amendments of the
    ACO, the EPA “decided to ‘reconsider’ the ACO by ‘adjudicating’ the issue of whether TVA had
    violated the CAA” before the EPA’s Environmental Appeals Board (“EAB”), which substantially
    “affirmed” the ACO. 
    Id. at 1245-46
    . The EPA chose to pursue the matter in front of the EAB rather
    than file an enforcement action because it believed that TVA could not be sued in federal court. 
    Id. at 1239
    . TVA petitioned for review of the EAB’s decision in the Eleventh Circuit, which ultimately
    concluded that critical aspects of the ACO procedure violated due process. 
    Id. at 1256-60
    . For this
    reason, the court further concluded that ACOs lack legal consequence and cannot constitute final
    agency action. Accordingly, the court held that it lacked jurisdiction over the dispute, and that the
    EPA must prove violations of the CAA in an enforcement action brought in U.S. district court rather
    than through its ACO procedure. 
    Id. at 1260
    . Apparently still clinging to its belief that it could not
    sue TVA in federal court, the EPA has not pursued such an action.
    On February 13, 2001, Plaintiffs National Parks Conservation Association (“National Parks”)
    and Sierra Club filed their original complaint. They amended the complaint to add Our Children’s
    Earth Foundation (“OCE”) as a plaintiff in November 2004. The essence of their complaint is that
    TVA violated the CAA and the Tennessee SIP by failing to obtain a PSD permit before it modified
    the Bull Run plant in 1988, and by continuing to operate the plant without such a permit, without
    having performed the required air-quality analysis, and without applying BACT. The result of these
    violations, according to the plaintiffs, is that TVA has evaded the appropriate emissions limitations
    No. 05-6329               Nat’l Parks Conservation Assoc. et al. v. TVA                                         Page 5
    of sulfur dioxide (SO2) and nitrogen oxides (NOx). To rectify these alleged wrongdoings, they seek
    declaratory relief, an injunction, and civil penalties to be paid to the EPA.
    C. Procedural History
    After National Parks and Sierra Club established organizational standing, the district court
    stayed all proceedings in April 2002 pending resolution of related litigation in the Eleventh Circuit.
    See TVA v. United States Envtl. Prot. Agency, 
    278 F.3d 1184
     (11th Cir. 2002), op. withdrawn in
    part, Whitman, 
    336 F.3d 1236
    . The district court lifted the stay in July 2004, and the following
    month, TVA moved for summary judgment on its statute of limitations defense. Before ruling on
    TVA’s motion, the district court granted the plaintiffs leave to file an amended complaint, which
    they did in November 2004.
    On December 9, 2004, the parties jointly moved the district court to decide TVA’s statute
    of limitations defense before ruling on its sovereign immunity defense. The district court granted
    this motion.
    After a hearing on TVA’s motion for summary judgment, the district court granted the
    motion and dismissed the plaintiffs’ complaint with prejudice. In its opinion, the district court
    concluded (1) that the plaintiffs did not establish a continuing violation of the CAA and the
    Tennessee SIP, (2) that the plaintiffs’ cause of action accrued in 1988, and (3) because the statute
    of limitations on the plaintiffs’ claim for civil penalties had run, the concurrent-remedy rule barred
    the plaintiffs’ claim for injunctive relief. The plaintiffs moved for reconsideration under Federal
    Rule of Civil Procedure 59(e) and for leave to amend under Rule 15. On July 22, 2005, the district
    court denied both motions. The plaintiffs now appeal.
    II. STANDARD OF REVIEW
    We review de novo a district court’s order granting summary judgment. DiCarlo v. Potter,
    
    358 F.3d 408
    , 414 (6th Cir. 2004). We will affirm a grant of summary judgment “if the pleadings,
    depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any,
    show that there is no genuine issue as to any material fact and that the moving party is entitled to
    a judgment as a matter of law.” Fed. R. Civ. P. 56(c). In reviewing the district court’s decision to
    grant summary judgment, we must view all evidence in the light most favorable to the nonmoving
    party. Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 
    475 U.S. 574
    , 587 (1986).
    III. ANALYSIS
    A. Statute of Limitations
    A five-year statute of limitations applies to any action “for the enforcement of any civil fine,
    penalty, or forfeiture.” 
    28 U.S.C. §3
     2462. The CAA provides for civil penalties of $25,000 per day
    per violation, 
    42 U.S.C. § 7413
    (b), and the plaintiffs’ first amended complaint seeks such penalties.
    The plaintiffs now argue that notwithstanding their request for civil penalties, this is not a case “for
    the enforcement of” such penalties because TVA is immune from liability for civil penalties.
    3
    Section 7413(b) explicitly authorizes only the EPA Administrator “to assess and recover a civil penalty” for
    a violation of “any requirement or prohibition of an applicable implementation plan or permit.” However, the citizen-suit
    provision authorizes “any person” to pursue a CAA action, and authorizes the district court “to apply any appropriate
    civil penalties.” 
    42 U.S.C. § 7604
    (a).
    The EPA raised the penalties to $27,500 per day for violations committed between January 30, 1997, and
    March 15, 2004, and to $32,500 per day for violations committed thereafter. 
    40 C.F.R. §§ 19.2
    , 19.4.
    No. 05-6329               Nat’l Parks Conservation Assoc. et al. v. TVA                           Page 6
    We recently concluded that “under any circumstances in which the State (or the United
    States) declines to raise sovereign immunity as a threshold defense, . . . the federal courts have
    discretion to address the sovereign-immunity defense and the merits in whichever order they prefer.”
    Nair v. Oakland County Cmty. Mental Health Auth., 
    443 F.3d 469
    , 477 (6th Cir. 2006). Here, TVA
    did not raise sovereign immunity “as a threshold defense,” e.g., by way of motion to dismiss.
    Instead, it (and, for that matter, the plaintiffs) requested that the district court reserve a decision on
    TVA’s immunity until after the court addressed TVA’s statute of limitations defense. The district
    court did so, and because it concluded that the plaintiffs’ claims were time-barred, never reached
    the immunity issue, which therefore is not presently before us. Under Nair, the district court’s
    reserving adjudication of TVA’s immunity defense was within its discretion. Accordingly, the
    plaintiffs’ request for civil penalties remains part of the operative complaint, and their suit is one
    “for the enforcement of” civil penalties. We hold that § 2462’s five-year statute of limitations
    applies.
    B. Continuing Violation
    Because § 2462 applies, for their suit to be timely, the plaintiffs must identify a wrongful act
    that took place within five years of their filing this suit. TVA argues, and the district court
    concluded, that the CAA and SIP prohibit only construction without a permit. The only construction
    here at issue (TVA’s replacing tubing in the Bull Run plant’s boiler) took place in 1988,4 so
    according to TVA, the statute of limitations for any violation premised upon that construction ran
    in 1993. The plaintiffs counter that TVA’s subsequent and continuing failures (1) to apply BACT
    and (2) to obtain a construction permit containing emissions limitations under the Tennessee SIP’s
    PSD provisions are actionable. We agree.
    Both parties, as well as the district court, framed this dispute as one regarding whether the
    plaintiffs have alleged a “continuing violation” of the CAA. Under the continuing-violation
    doctrine, the court can consider as timely all relevant violations “including those that would
    otherwise be time[-]barred.” Sharpe v. Cureton, 
    319 F.3d 259
    , 267 (6th Cir.) (internal quotation
    marks omitted), cert. denied, 
    540 U.S. 876
     (2003). See also Gandy v. Sullivan County, 
    24 F.3d 861
    ,
    864 (6th Cir. 1994) (“The doctrine . . . may allow a court to impose liability on [a defendant] for acts
    committed outside the limitations period.”).
    We previously have said that “[c]ourts have been extremely reluctant to apply this doctrine
    outside the context of Title VII.” LRL Props. v. Portage Metro Hous. Auth., 
    55 F.3d 1097
    , 1105 n.3
    (6th Cir. 1995). Since then, we nonetheless have applied the continuing-violation doctrine to claims
    for deprivations of civil rights. See, e.g., Tolbert v. Ohio Dep’t of Transp., 
    172 F.3d 934
     (6th Cir.
    1999) (applying continuing-violation theory in action brought under 
    42 U.S.C. § 1983
     alleging
    racially discriminatory allocation of highway sound barriers); Kuhnle Bros., Inc. v. County of
    Geauga, 
    103 F.3d 516
     (6th Cir. 1997) (considering continuing-violation doctrine in case involving
    takings claim and due process claims for deprivations of liberty and property). No opinion has
    articulated a principled reason why the continuing-violation doctrine should be limited to claims for
    deprivations of civil rights and employment discrimination, and other courts have considered the
    continuing-violation doctrine in environmental disputes. See, e.g., United States v. Duke Energy
    Corp., 
    278 F. Supp. 2d 619
     (M.D.N.C. 2003) (concluding violations of the North and South Carolina
    SIPs’ PSD provisions are continuing violations); New York v. Niagara Mohawk Power Corp., 
    263 F. Supp. 2d 650
    , 660-63 (W.D.N.Y. 2003) (concluding violations of federal PSD regulations are not
    continuing violations); United States v. Westvaco Corp., 
    144 F. Supp. 2d 439
    , 442-44 (D. Md. 2001)
    (concluding violations of Maryland PSD regulations are not continuing violations).
    4
    Under 
    42 U.S.C. § 7479
    (2)(C), “construction” includes modification.
    No. 05-6329               Nat’l Parks Conservation Assoc. et al. v. TVA                                          Page 7
    We need not decide whether the continuing-violation doctrine applies in environmental suits,
    as we conclude this case presents a series of discrete violations rather than a single violation that
    may or may not be “continuing” in nature. Courts have long distinguished continuing violations,
    which toll the applicable statutes of limitations, from repetitive discrete violations, which constitute
    independently actionable individual causes of action. For instance, in Gandy, we noted that each
    check based on a discriminatory method of calculating pay constitutes a separate violation of the
    Equal Pay Act, and we concluded that the plaintiff was entitled to a recovery based on any such
    checks received within the limitations period. 
    24 F.3d at 863-64
    . We further recognized, “Although
    [the cause of action is] ‘continuing in nature,’ invocation of the continuing violations doctrine is not
    necessary since plaintiffs . . . are not attempting to file an otherwise untimely action and are not
    attempting collection of damages for conduct outside the limitations period.” 
    Id. at 864
    .
    Additionally, in Knight v. Columbus, 
    19 F.3d 579
     (11th Cir.), cert. denied, 
    513 U.S. 929
    (1994), the Eleventh Circuit noted, “The term ‘continuing violation’ suggests that the original
    violation . . . is somehow the source of the [plaintiffs’] present ability to recover.” 
    Id. at 582
    . The
    Knight court continued, “The term ‘continuing violation’ also implies that there is but one incessant
    violation and that the plaintiffs should be able to recover for the entire duration of the violation,
    without regard to the fact that it began outside the statute of limitations.” 
    Id.
     There, the plaintiffs
    sought recovery under the Fair Labor Standards Act (“FLSA”) for the city’s failure to pay them for
    overtime they worked. The city argued that their claims were time-barred because the decision to
    classify the employees as exempt from the FLSA’s overtime provisions occurred outside the
    limitations period. Noting that the conduct prohibited by the FLSA is failing to pay overtime, the
    court concluded that each paycheck that did not compensate the plaintiffs for overtime constituted
    a new violation. Accordingly, the court recognized that the plaintiffs did not assert a single
    “continuing violation,” but instead sought recovery for “a series of repeated violations of an
    identical nature” in which “each violation gives rise to a new cause of action,” 
    id.,
     and held that the
    plaintiffs were entitled to recover for each such violation that occurred within the limitations period.
    Similarly, in the context of Title VII discrimination charges filed with the EEOC, the
    Supreme Court has instructed that “[e]ach discrete discriminatory act starts a new clock for filing
    charges alleging that act.” Nat’l R.R. Passenger Corp. v. Morgan, 
    536 U.S. 101
    , 113 (2002).
    Accordingly, the Court held that a plaintiff may recover for all discrete acts of discrimination that
    occur within the limitations period. 
    Id. at 105, 114
    . See Sharpe, 
    319 F.3d at 267-68
     (applying
    Morgan to claims under 
    42 U.S.C. § 1983
    ).
    Notably, in each of these cases, the court’s analysis began with a careful examination of the
    specific conduct prohibited by the statute at issue.5 In Gandy, it was paying female employees
    unequally for equal work; in Knight, the prohibited conduct was failing to pay time-and-a-half for
    overtime hours worked; and in Morgan, it was discrete acts or occurrences of discrimination, such
    as suspension or termination. We follow these examples, and turn now to the precise conduct
    prohibited by the CAA.
    C. Actionable Conduct
    The CAA’s citizen-suit provision authorizes the plaintiffs to sue anyone “who is alleged to
    have violated (if there is evidence that the alleged violation has been repeated) or to be in violation
    of (A) an emission standard or limitation under this chapter.” 
    42 U.S.C. § 7604
    (a)(1). An “emission
    standard or limitation under this chapter” includes “any . . . standard, limitation, or schedule
    established under any permit issued . . . under any applicable State implementation plan approved
    5
    The same is true for cases analyzed as potential continuing violations under Tolbert v. Ohio Department of
    Transportation, 
    172 F.3d 934
    , 941 (6th Cir. 1999), because the first prong of the test articulated in Tolbert requires the
    court to identify the “wrongful conduct” alleged in the complaint.
    No. 05-6329           Nat’l Parks Conservation Assoc. et al. v. TVA                            Page 8
    by the [EPA] Administrator, any permit term or condition, and any requirement to obtain a permit
    as a condition of operations.” 
    Id.
     § 7604(f)(4) (emphasis added). So defined, the provisions of the
    particular state’s SIP determine what conduct is actionable under the CAA. For the plaintiffs’
    claims to be timely, then, they must identify (1) a standard or limitation that TVA violated or (2) any
    required permit that it failed to obtain, within five years of bringing this suit.
    1. Failure to Apply BACT
    The district court never determined whether the 1988 project at Bull Run constitutes a “major
    modification,” as is required for the PSD regulations to apply to the project. See TENN. COMP. R.
    & REGS. 1200-3-9-.01(4)(c). Accordingly, that issue is not before us. Because on summary
    judgment we are required to view all evidence in the light most favorable to the opponents of the
    motion, here the plaintiffs, we assume without deciding that the project constitutes a major
    modification and that the PSD requirements of Tennessee’s SIP apply.
    One provision of the PSD regulations states, “A major modification shall apply best
    available control technology for any pollutant for which it would result in a significant net emissions
    increase at the source.” Id. § 1200-3-9-.01(4)(j)(3) (emphasis added). This provision, by its own
    terms, creates an ongoing obligation to apply BACT, regardless of what terms a preconstruction
    permit may or may not contain. Even if TVA had obtained a construction permit that did not require
    BACT, such an approval “shall not relieve any owner or operator of the responsibility to comply
    fully with applicable provisions under [the Tennessee SIP] and any other requirements under local,
    State, or Federal law.” Id. § 1200-3-9-.01(4)(a)(5). Because the SIP requires that modified sources
    apply BACT, TVA may not rely on any preconstruction approval to justify its post-construction
    failure to comply with this provision (again, assuming that the Bull Run overhaul was a “major
    modification”).
    Under § 1200-3-9-.01(4)(j), failing to apply BACT is actionable, and this cause of action
    manifests itself anew each day a plant operates without BACT limits on emissions. The violations
    that plaintiffs allege thus occurred both inside and outside the limitations period. We hold that
    insofar as the plaintiffs seek assessment of penalties for violations occurring prior to February 13,
    1996, their actions are time-barred. Insofar as they seek penalties for later violations, their claims
    are timely.
    2. Failure To Obtain Appropriate Construction Permit After Construction
    The plaintiffs also show that TVA violated its ongoing requirement to obtain the appropriate
    construction permit after completing construction. Tennessee’s SIP forbids “the construction . . .
    or the modification of an air contaminant source” unless the owner or operator first “applie[s] for
    and receive[s] from the Technical Secretary a construction permit for the construction or
    modification of such air contaminant source.” TENN. COMP. R. & REGS. § 1200-3-9-.01(1)(a). This
    provision appears to support TVA’s position — i.e., that the SIP prohibits only construction without
    a permit.
    However, under the Tennessee SIP, the obligation to obtain an appropriate permit is ongoing,
    and applies even to those sources that did not obtain the appropriate permits before construction:
    “In the case where a source or modification was constructed without first obtaining a construction
    permit, a construction permit may be issued to the source or modification to establish as conditions
    of the permit, the necessary emissions limits and requirements to assure that these regulatory
    requirements are met.” Id. § 1200-3-9-.01(1)(e). In other words, while § 1200-3-9-.01(1)(a)
    contains the Tennessee SIP’s preconstruction permitting requirement, § 1200-3-9-.01(1)(e)
    establishes that the duty to obtain a construction permit containing the proper emissions limits is
    ongoing, even post-construction.
    No. 05-6329              Nat’l Parks Conservation Assoc. et al. v. TVA                                     Page 9
    Despite § 1200-3-9-.01(1)(e)’s seemingly permissive language (“may be issued”), the
    provision’s following sentence reveals that obtaining a permit guaranteeing “that ambient air quality
    standards and other regulatory requirements will be met” is mandatory, as it requires that “[t]he
    appropriate enforcement action shall be pursued.” Id. (emphasis added). The PSD provisions of
    Tennessee’s SIP, id. § 1200-3-9-.01(4), are among these “other regulatory requirements.”
    TVA admits that it never received a permit containing emissions limitations under the
    Tennessee SIP’s PSD provisions. Consequently, TVA has been, and remains, in violation of § 1200-
    3-9-.01(1)(e)’s requirement that it obtain a permit containing “the necessary    emission limits and
    requirements to ensure that [the SIP’s] regulatory requirements are met.”6 Like the alleged failure
    to apply BACT, this alleged violation manifests itself each day the plan operates. Accordingly, we
    hold that the violations predating February 13, 1996 are time-barred, while the remaining violations
    are not.
    D. Concurrent-Remedy Rule
    Because we conclude that the plaintiffs’ claims for civil penalties are timely under 
    28 U.S.C. § 2462
     insofar as they relate to violations occurring within five years of February 13, 2001, we need
    not address the district court’s application of the concurrent-remedy rule.
    IV. CONCLUSION
    For the foregoing reasons, we conclude that the plaintiffs’ claims for civil penalties are
    timely insofar as they relate to violations that occurred within five years of the date they filed their
    initial complaint. Accordingly, we REVERSE the district court’s decision to the contrary, and
    REMAND for further proceedings consistent with this opinion.

    This, of course, assumes that the Bull Run project was a major modification to which the PSD regulations
    apply. On remand, the district court may determine whether the project constituted a major modification under TENN.
    COMP. R. & REGS. § 1200-3-9-.01(4)(b)(2), including whether the project “result[ed] in a significant net emissions
    increase of any pollutant subject to regulation.”

    ________________
    DISSENT
    ________________
    ALICE M. BATCHELDER, Circuit Judge. I respectfully dissent because I do not agree that
    this case involves a “series of discrete violations.” I believe this case involves, at most, a single
    violation that occurred in 1988, and therefore, its statute of limitations expired five years later. I
    would affirm the district court.
    Under Tennessee law, the TVA was required to obtain two separate permits: a construction
    permit, see 
    Tenn. Comp. R. & Regs. 1200
    -3-9.01; and an operating permit, see 
    id.
     at .02. The TVA
    has an operating permit and no one in the present case has alleged any violation of it. The claim
    here is that because the TVA failed to obtain a construction permit prior to its plant modification in
    1988 (or any time since), it is emitting pollutants above the allowable BACT levels. Based on my
    reading of the law, I would hold that, even if this claim is true, this condition constitutes a series of
    discrete harms and not a series of discrete violations.
    By way of example, suppose I contracted with a carpenter to repair the roof of my home.
    If he failed to do so, then he would have breached the contract – a single violation. Under this
    scenario, I suffer a new harm every time it rains, i.e., every time water comes into my living room
    through the faulty roof. The carpenter does not, however, breach the contract anew every time it
    rains; that is, the carpenter does not commit a new and discrete violation. I believe the same
    reasoning applies to the present case, and this reasoning is consistent with Tolbert v. Ohio
    Department of Transportation, 
    172 F.3d 934
    , 940 (6th Cir. 1999) (distinguishing “continuing ill
    effects” from “continuing unlawful acts”). To complete the present example: if a violation (rather
    than merely a new harm) occurs each time it rains, then the corollary is that it must rain in order for
    a violation to occur, and under such a theory, I would not be able to sue the carpenter for breaching
    the contract to repair my roof until after I had suffered through at least one rain storm. In truth,
    however, I could sue the carpenter as soon as I became aware of his breach of the contract; I need
    not wait for it to rain, and if I were to wait, I would likely be held accountable for such a delay.
    Returning to the present case, let us assume, arguendo, that the TVA was in fact required
    to obtain a construction permit before beginning its modification of the Bull Run plant in 1988. By
    failing to do so, it committed a violation. Under this scenario, the plaintiffs may have suffered a new
    harm every time thereafter that the plant was in operation (i.e., emitting pollutants above the BACT
    levels), but just as with the carpenter, the TVA did not violate the construction permit requirement
    anew every time the plant was operating. That is, the TVA did not commit a new and discrete
    violation of the construction permit requirement every time it operated the plant, particularly if the
    TVA was in compliance with its operating permit. To complete this reasoning; if a violation (rather
    than merely a harm) occurs each time the plant operates, then the corollary is that the plant must
    operate in order for a violation to occur, and under such a theory, there would be no violation for
    failing to obtain a construction permit until after the TVA had operated the plant at least one time.
    While that is an apt description of an operating permit, it is an inapt description of a construction
    permit.
    Because I find this “discrete violations” approach unsupported by law or reason, I must
    respectfully dissent. This seems to me to be the plaintiffs’ strained attempt to circumvent their
    failure to act within the statute of limitations. If they have a claim that the TVA is violating its
    operating permit by emitting pollutants in excess of BACT levels, then they should file that claim.
    The present claim, however, expired in 1993. I would affirm.
