    Opinion for the Court filed by BROWN, Circuit Judge.
    BROWN, Circuit Judge: On March 1, 2016, North
    Dakota filed a motion to modify an injunction governing the
    Northwest Area Water Supply Project (“NAWS” or “the
    Project”). In a minute order, the district court stated North
    Dakota did not “present either changes in law or facts
    sufficient to warrant modifying the injunction” and summarily
    denied the motion “for the reasons argued by the
    [nonmovants].” J.A. 45. North Dakota appealed, and we
    remand with directions to grant the modification. See 
    28 U.S.C. § 2106
    ; Pasadena City Bd. of Educ. v. Spangler, 
    427 U.S. 424
    , 440 (1976).
    I.
    A.
    For at least twenty years, North Dakota and the Bureau
    of Reclamation (“the Bureau”)—a unit within the Department
    of the Interior—have attempted to design and construct
    NAWS, a project designed to ameliorate North Dakota’s
    longstanding difficulties in obtaining sufficient quantities of
    high-quality drinking water. 1 See Gov’t of Manitoba v.
    1
    The Project will cost approximately $145 million to construct.
    North Dakota will provide thirty-five percent of the funding, and

    398 F. Supp. 2d 41
    , 48 (D.D.C. 2005) (stating
    development of the first Environmental Assessment began in
    June 1997). If approved, the Project would withdraw water
    from the Missouri River Basin and transport it via a 45-mile-
    long pipeline to the Hudson Bay Basin located in Northwest
    North Dakota. 
    Id. at 44
    . Thus, it would provide a new water
    source to approximately 81,000 citizens of North Dakota
    living within the Project communities. Gov’t of Manitoba v.
    Salazar, 
    691 F. Supp. 2d 37
    , 43 (D.D.C. 2010).
    The Project falls under the auspices of the National
    Environmental Policy Act (“NEPA”). 
    42 U.S.C. § 4321
    , et
    seq. NEPA imposes “a set of action-forcing procedures”
    requiring federal agencies to take a “hard look” at any
    potential environmental consequences associated with their
    “proposals and actions” and to broadly disseminate relevant
    environmental information. Dep’t of Transp. v. Pub. Citizen,
    
    541 U.S. 752
    , 756–57 (2004); Robertson v. Methow Valley
    Citizens Council, 
    490 U.S. 332
    , 350 (1989). Unfortunately
    for those living within the Project communities, the Bureau’s
    repeated failures to comply with NEPA’s requirements have
    left the Project mired in legal challenges for fourteen years
    (and counting).
    One of NEPA’s “action-forcing” procedures directs
    agencies to prepare an environmental impact statement
    (“EIS”) for “major [f]ederal actions significantly affecting the
    quality of the human environment.” 
    42 U.S.C. § 4332
    (C). To
    determine whether a project constitutes a “major federal
    action,” agencies begin by preparing an environmental
    assessment (“EA”). See 
    40 C.F.R. § 1508.9
    ; see also Nat’l
    Audubon Soc’y v. Hoffman, 
    132 F.3d 7
    , 12 (2d Cir. 1997). If
    the proposed action is not a “major federal action,” the agency
    the federal government will provide sixty-five percent. Gov’t of
    Manitoba v. Norton, 
    398 F. Supp. 2d 41
    , 54 (D.D.C. 2005).
    4
    issues a finding of no significant impact (“FONSI”), which
    “briefly present[s] the reasons why an action . . . will not have
    a significant effect on the human environment.” 
    40 C.F.R. § 1508.13
    . If it is a major federal action, the agency prepares
    the EIS, which must discuss the action’s general impact, its
    unavoidable adverse impacts, its alternatives, the relationship
    between short-term environmental use and the “maintenance
    and enhancement of long-term productivity,” and “any
    irreversible or irretrievable commitments of resources” should
    the proposal be implemented. 
    42 U.S.C. § 4332
    (C); see also
    
    id.
     § 4332(E) (“[A]ll agencies of the Federal Government
    shall . . . study, develop, and describe appropriate alternatives
    to recommended courses of action in any proposal which
    involves unresolved conflicts concerning alternative uses of
    available resources.”).
    After issuing an EIS, the agency must also issue a record
    of decision (“ROD”), which is a “concise public record” that
    describes the agency’s decision, “[i]dentif[ies] all alternatives
    considered by the agency,” and states “whether all practicable
    means to avoid or minimize environmental harm from the
    alternative selected have been adopted.” 
    40 C.F.R. § 1505.2
    .
    An agency must publish notice in the Federal Register that it
    has filed a final EIS (“FEIS”) with the Environmental
    Protection Agency, and it cannot approve the ROD until thirty
    days have passed from the date of that notice. 
    40 C.F.R. § 1506.10
    (b)(2); 
    23 C.F.R. § 771.127
    (a). The issuance of a
    ROD constitutes final agency action.
    B.
    In 2001, the Bureau issued an EA and FONSI for NAWS.
    Construction began in 2002, but, six months later, the
    Province of Manitoba challenged the sufficiency of the EA
    and FONSI on the grounds that they did not adequately
    5
    grapple with potential ecological problems caused by
    transferring treatment-resistant biota into the Hudson Bay
    Basin. Gov’t of Manitoba v. Norton, 
    398 F. Supp. 2d 41
    , 44–
    45, 49 (D.D.C. 2005). According to the 2001 EA, water
    would be withdrawn from the Missouri River, “partially
    disinfected and pre-treated,” travel via buried pipeline across
    the continental divide into the Hudson Bay Basin, and then
    receive final treatment. 
    Id. at 46
    . Project water “would drain
    into the Souris River, which flows into Manitoba.” 
    Id.
     at 47–
    48. Manitoba claimed the Project would not adequately treat
    the water, resulting in the transfer of non-native biota into the
    Hudson Bay Basin. This could “eliminate indigenous species,
    cause reduced growth and survival rates in indigenous
    species, and change the trophic structure of fish
    communities.” 
    Id. at 45
    . North Dakota intervened as a
    Defendant. In February 2005, on cross-motions for summary
    judgment, the district court agreed with Manitoba, remanding
    the case to the Bureau for further NEPA work on this point.
    
    Id. at 66
    .
    After the remand, Manitoba asked the district court to
    grant a permanent injunction governing all NAWS-related
    activities. Otherwise, it argued North Dakota would “plunge
    ahead” with construction so as to “create a fait accompli, limit
    the ‘freedom of choice’ essential to sound decision-making
    under NEPA[,] and risk irreversible environmental
    consequences.” J.A. 53. Though the court noted the
    importance of “preserv[ing] for the agency the widest
    freedom of choice when it reconsiders its action after coming
    into compliance with NEPA,” J.A. 53, it weighed that interest
    against “the avoidance of unnecessary delay in the delivery of
    a reliable source of high quality water to approximately
    81,000 people,” J.A. 54. The court also noted “the public
    interest is best preserved by ensuring attention to
    environmentally sensitive decision-making through the least-
    6
    intrusive means necessary.” J.A. 55. Thus, rather than
    granting a full injunction, it permitted North Dakota to move
    forward with construction that would not impact the
    “opportunity for sound decision-making under NEPA.” J.A.
    55. Additionally, “[b]efore any other NAWS construction
    may proceed, the government must return to the Court to
    demonstrate why the proposed additional construction would
    not influence or alter the agency’s ability to choose between
    water treatment options.” J.A. 55 (emphasis added).
    The Bureau completed its next NEPA analysis in January
    2009. This time, the Bureau prepared an EIS rather than a
    FONSI, but it still identified the Missouri River as the Project
    source. However, its second attempt fared no better when
    subjected to judicial review.
    Manitoba claimed the EIS still did not adequately address
    the transfer of treatment-resistant bacteria. Missouri filed a
    separate challenge, alleging the EIS did not properly account
    for cumulative effects of water withdrawal from the Missouri
    River. See Complaint, Missouri ex rel. Koster v. U.S. Dep’t
    of Interior, Bureau of Reclamation, No. 1:09-cv-00373
    (D.D.C. Feb. 24, 2009), ECF No. 1. The cases were
    consolidated in 2009 and, together, Manitoba and Missouri
    moved for summary judgment. They argued the Bureau had
    not taken a hard look at (1) reasonable alternatives to the
    Project, (2) “the cumulative impacts of the Project on
    Missouri River water levels,” and (3) the consequences of
    bacteria transfer. Gov’t of Manitoba v. Salazar, 
    691 F. Supp. 2d 37
    , 45 (D.D.C. 2010). On March 5, 2010, the court again
    remanded to the Bureau for further consideration of the
    second and third issues. 
    Id. at 51
    . The court chastised the
    Bureau for “wast[ing] years by cutting corners and looking
    for short cuts,” 
    id.,
     as well as its “breathtaking” misreading of
    the court’s 2005 opinion, 
    id. at 50
    .
    7
    After the second remand, the Bureau engaged in a third,
    full-blown NEPA analysis that not only considered the two
    remanded issues, but also “reexamin[ed] and updat[ed] all
    prior NEPA analyses” associated with the Project. J.A. 719.
    The Bureau issued the final supplemental EIS (“FSEIS”) in
    April 2015, and the ROD followed in August. The documents
    again identified the Missouri River as the selected Project
    alternative, with supplemental water taken from the Minot
    and Sundre aquifers, both of which are located in North
    Dakota. The FSEIS also included provisions for a water-
    treatment plant in North Dakota that, among other things,
    would inactivate treatment-resistant bacteria before the water
    transferred to the Hudson Bay Basin.
    In January 2016, Missouri and Manitoba challenged the
    FSEIS once again. Summary judgment motions are currently
    pending before the district court.
    C.
    On March 1, 2016, North Dakota filed a motion to
    modify the 2005 injunction, seeking permission to begin
    “paper design” of the proposed water-treatment plant. On
    June 14, 2016, the district court issued the following minute
    order (“Order”) denying North Dakota’s request:
    North Dakota asks this Court to further modify
    an injunction first issued in 2005 “to permit it
    only to undertake design work for the biota
    water treatment plant (‘Biota WTP’) to be
    located in Max, North Dakota,” once a federal
    [FEIS] has been reviewed and approved.
    North Dakota assumes its own victory
    defending the FEIS. Since that briefing has
    just begun, the Court intimates no view on the
    matter but sees nothing in the Motion to
    8
    present either changes in law or facts sufficient
    to warrant modifying the injunction again now.
    This motion is denied for the reasons argued
    by the Province of Manitoba and the State of
    Missouri.
    J.A. 45.
    On appeal, 2 North Dakota now asks for a remand with
    instructions to grant its requested modification. We have
    jurisdiction under 
    28 U.S.C. § 1292
    (a)(1).
    II.
    A.
    Under Federal Rule of Civil Procedure 60(b)(5), courts
    may afford relief from an injunction, including modification,
    where prospective application of the order is “no longer
    equitable.” The party seeking modification “bears the burden
    of establishing that a significant change in circumstances
    warrants [its] revision.” Rufo v. Inmates of Suffolk Cty. Jail,
    
    502 U.S. 367
    , 383 (1992); Horne v. Flores, 
    557 U.S. 433
    , 447
    (2009). “A party . . . may meet [this] initial burden by
    showing . . . a significant change either in factual conditions
    or in law.” Rufo, 
    502 U.S. at 384
    . In particular, modification
    is appropriate “when enforcement . . . without modification
    would be detrimental to the public interest.” Id.; Horne, 
    557 U.S. at 453
     (noting the Rule 60(b)(5) inquiry “asks only
    whether a significant change either in factual conditions or in
    law renders continued enforcement of the judgment
    detrimental to the public interest”). If a movant meets this
    burden, the Court has even opined “a court abuses its
    discretion when it refuses to modify an injunction . . . in light
    2
    The federal defendants are not participating in this appeal.
    9
    of such changes.” Horne, 
    557 U.S. at 447
    ; Agostini v. Felton,
    
    521 U.S. 203
    , 215 (1997); see also Valero Terrestrial Corp. v.
    Paige, 
    211 F.3d 112
    , 122 (4th Cir. 2011) (noting modification
    “is required where there has been a significant change either
    in factual conditions or in law” (emphasis added)). At the
    very least, “the court should consider whether the proposed
    modification is suitably tailored to the changed
    circumstance.” Rufo, 
    502 U.S. at 383
    .
    In the context of institutional reform litigation, where, as
    here, injunctions typically remain in place for many years,
    this Court and the Supreme Court have also recognized the
    need to employ a “flexible” approach to modification
    requests. See 
    id. at 380
     (noting that, “[b]ecause such decrees
    often remain in place for extended periods of time, the
    likelihood of significant changes occurring during the life of
    the decree is increased”); Horne, 
    557 U.S. at 453
     (same);
    Petties ex rel. Martin v. District of Columbia, 
    662 F.3d 564
    ,
    568–69 (D.C. Cir. 2011) (same). 3 “[T]he public interest is a
    3
    The district court has followed this guidance, as it has revisited
    and considered modifications to the injunction on five previous
    occasions. Most recently, in 2013—i.e., after the 2010 remand and
    before the 2015 FSEIS—the court undertook a sua sponte review of
    the injunction. The parties had submitted a joint status report in
    October 2012, which had provided information about the Bureau’s
    plans to engage in additional pipeline construction in 2013. The
    court held it would not permit Project work that could influence the
    Bureau’s choices about how to address treatment-resistant bacteria,
    as well as the “fundamental question of the water source for
    NAWS.” Gov’t of Manitoba v. Salazar, 
    926 F. Supp. 2d 189
    , 192–
    93 (D.D.C. 2013) (noting that, because of the consolidation with
    Missouri’s separate challenge, “the question of the source of the
    water is now part of the focus as well”). The court also stated its
    opinion reflected an “identical” purpose to its 2005 decision: “to
    fashion a more tailored remedy that permits the [P]roject to move
    10
    particularly significant reason for applying a flexible
    modification standard” where, as here, the injunction
    “reach[es] beyond the parties involved directly in the suit.”
    Rufo, 
    502 U.S. at 381
    ; Petties, 
    662 F.3d at 569
    . Finally,
    courts should keep in mind how long-term injunctions can
    impact a State’s ability “to make basic decisions” for itself
    and its citizens. See Horne, 
    557 U.S. at
    447 n.3 (describing
    this as one of the “features and risks” of long-term
    institutional reform litigation).
    B.
    We review a district court’s denial of a 60(b)(5) motion
    for abuse of discretion. Pigford v. Johanns, 
    416 F.3d 12
    , 20
    (D.C. Cir. 2005). Mere brevity does not provide sufficient
    grounds to find an abuse of discretion has occurred. See, e.g.,
    
    id. at 18
    . Likewise, Federal Rule of Civil Procedure
    52(a)(3)—which applies to rulings on Rule 60(b) motions—
    does not require written findings and conclusions. See also
    FED. R. CIV. P. 52(a) advisory committee’s note to 1946
    amendment (noting “the judge need only make brief, definite,
    pertinent findings and conclusions upon the contested matters;
    there is no necessity for over-elaboration of detail or
    particularization of facts”).
    Even so, in this circumstance, we conclude the district
    court did abuse its discretion. Its Order denied North
    Dakota’s motion for the “reasons argued” by the nonmovants.
    J.A. 45. This explanation can only be interpreted as a
    wholesale adoption of the nonmovants’ arguments, which
    contain a number of dubious factual claims. For instance,
    Manitoba argued that, “[a]fter more than fifteen years[,] the
    Bureau has still not produced an environmental analysis that
    forward . . . while preserving the opportunity for sound decision-
    making under NEPA.” Id. at 192.
    11
    passes NEPA muster,” J.A. 137, but this is the very question
    at issue in the summary judgment motions currently pending
    before the court. See also J.A. 142 n.10 (attacking the
    sufficiency of the FSEIS on the merits). Additionally, as will
    be discussed further below, the quantity of water within the
    Project community became a central issue in the modification
    request. But Manitoba sought to demonstrate water quantity
    had not diminished by presenting data from aquifers that
    North Dakota argued were not part of NAWS. Compare J.A.
    145 (Manitoba’s water-quantity data from the Little Muddy
    aquifer), with J.A. 1200–10 (list of Project aquifers from the
    FSEIS, which does not include Little Muddy), and Gov’t of
    Manitoba v. Norton, No. 1:02-cv-02057 (Apr. 25, 2016), ECF
    No. 233-2 ¶ 3 (declaration of NAWS Project Manager stating
    “[t]he Little Muddy aquifer is not located in an area expected
    to be served by NAWS”); compare J.A. 146 (Manitoba’s
    water-quantity data from New Rockford aquifer), with Gov’t
    of Manitoba, No. 1:02-cv-0205, ECF No. 233-2 ¶ 3
    (declaration of NAWS Project Manager stating “[t]he New
    Rockford aquifer is heavily appropriated and incapable of
    providing useful water supplies in the project area”). The
    Order does not explain why, despite this factual dispute, the
    court found Manitoba’s presentation of data not only relevant,
    but also more persuasive. 4 Without a more nuanced and
    detailed explanation, the district court’s acceptance of the
    nonmovants’ arguments in toto constitutes an abuse of
    discretion. We therefore turn next to determining whether
    North Dakota met its burden under Rule 60(b)(5).
    4
    The district court also does not explain why it believes paper
    design work constitutes “construction” under the terms of the
    original injunction. See J.A. 55.
    12
    III.
    A.
    At the outset, we note North Dakota significantly
    handicapped its own motion by erroneously asking the district
    court to apply the four factors set out in Winter v. Natural
    Resources Defense Council, 
    555 U.S. 7
    , 20 (2008), 5 as
    opposed to the standards under Rule 60(b)(5). This forced
    Manitoba and Missouri to respond not only by rebutting
    North Dakota’s Winter arguments, but also by anticipating
    and defending against North Dakota’s assertions as though
    they had been presented through the proper framework. The
    error also undisputedly impacted the district court’s ability to
    evaluate the parties’ competing claims. Analyzing North
    Dakota’s request thus necessitates fleshing out its arguments
    in some detail.
    Despite its legal error, North Dakota’s opening and reply
    briefs before the district court identified three changed
    circumstances that the state claimed justified a modification.
    First, water quality and quantity concerns had become more
    acute and “continued to deteriorate.” J.A. 86–87 (listing
    examples of deterioration). Second, the Bureau’s completed
    FSEIS and ROD eliminated any concern that the modification
    5
    These factors include (1) the likelihood of success on the merits;
    (2) whether plaintiffs are likely to suffer irreparable harm in the
    absence of injunctive relief; (3) whether the balance of the equities
    tips in the plaintiffs’ favor; and (4) whether the injunction is in the
    public interest). 
    555 U.S. at 20
    .
    13
    would compromise the NEPA decisionmaking process. 6
    Third, “[d]ue to the state’s biennial budget cycle, if funding
    requests for this design work [were] not submitted by
    [Summer of 2016], funding may not become available until
    mid-2019.” 7 J.A. 82; see also J.A. 165 (noting, in its reply
    brief to the district court, that “if the injunction is not
    modified before budget submissions in July, the available
    funds will likely remain unspent, leading to further budget
    reductions in 2017–19”).
    In support of its motion, North Dakota attached a
    declaration submitted by Timothy Freije—NAWS’s Project
    Manager—stating the paper design work would take
    approximately twenty months to complete, and physical
    construction would require an additional two years. Thus, at a
    minimum, the plant would take four years to construct. Freije
    also stated the plant’s paper design was the most time-
    consuming Project component. North Dakota also attached a
    copy of a Memorandum of Understanding (“the MOU”) it had
    entered into with the Bureau, wherein North Dakota agreed to
    fund the paper design work at its own expense “until the
    NAWS injunction is lifted or the litigation is otherwise
    resolved.” J.A. 106. It did not, however, attach any concrete
    data demonstrating decreased water quantity or quality.
    6
    Though not presented as a stand-alone argument until its reply
    brief, North Dakota discussed the FSEIS and ROD sufficiently in
    its opening brief to avoid waiver. For instance, it argued “the
    requested design work cannot create an undue influence on [the
    Bureau’s] NEPA review, which is complete.” J.A. 93. Elsewhere,
    it noted “[t]his requested relief presents zero risk of environmental
    harm to any party and will in no way influence the [NEPA] process
    that was completed with [the Bureau’s] issuance in 2015 of a
    [FSEIS] and ROD.” J.A. 81.
    7

    To counter North Dakota’s water quantity argument,
    Manitoba presented daily water level data from the years
    2000 to 2016 for the Sundre, Little Muddy, and New
    Rockford aquifers. Each graph depicts significant variety in
    water levels, but all three show a general trend downward
    until about 2009, followed by a general upward trajectory that
    peaks between 2012 and 2014. See J.A. 144–46. Water
    levels in the Sundre and Little Muddy aquifers currently sit
    above where they rested in 2005.
    North Dakota rebutted the relevance of this data by
    noting the Little Muddy aquifer lies outside the Project area.
    It also provided a second declaration from Freije, which stated
    the New Rockford aquifer “is already heavily appropriated
    . . . and is therefore incapable of serving as a useful municipal
    water supply.” J.A. 163. Additionally, in its reply brief to the
    district court, North Dakota described the upward trend in
    water levels as temporary, noting the state experienced
    significant flooding during 2011. It presented hydrograph
    data demonstrating water levels had subsequently dropped
    and argued 2011’s anomaly could not be used to predict water
    levels going forward. 8
    Regarding water quality, North Dakota referenced
    (without supporting data) increased levels of arsenic, total
    8
    These hydrographs were for the Minot and Sundre aquifers. The
    Minot hydrograph indicates water levels rose in 2011 from
    approximately 1500 feet above NAVD88 to 1520 feet. By 2016,
    that level had dropped to 1507 feet. J.A. 173. At the Sundre
    aquifer, water levels rose in 2011 from approximately 1485 feet
    above NAVD88 to approximately 1510 feet. In 2016, that level
    hovered around 1508 feet. J.A. 174. At oral argument, counsel
    stated “two thirds” of the water gained through flooding had
    already been lost at the Minot aquifer. See Oral Arg. Recording
    3:47–4:11.

    dissolved solids (“TDS”), sodium, iron, and manganese in its
    opening brief to the district court. In response, Manitoba
    presented water-quality tables from Minot, one of the areas
    served by the Project, spanning the years 2011 to 2014.
    These tables reflect that sodium and TDS levels remained
    constant throughout this timeframe, and a 2002 Minot water-
    quality report attached to North Dakota’s reply brief also
    recorded the same levels for these minerals. J.A. 134–35,
    176.
    However, comparing the 2002 and 2013 water-quality
    reports indicates arsenic levels have risen from 1.23 parts per
    billion in 2002 to 3.41 parts per billion in 2013. 9 Though still
    falling within the Safe Drinking Water Act’s safe drinking
    water standards, see 42 U.S.C. § 300f, et seq., the reports
    nevertheless demonstrate an almost threefold increase in
    arsenic during the course of the injunction’s lifespan.
    B.
    We conclude North Dakota presented two changed
    circumstances sufficient to justify granting its narrow
    modification.
    First, issuance of the FSEIS and ROD constitutes a
    “significant change . . . in factual conditions” that “renders
    continued enforcement of the judgment detrimental to the
    public interest.” Horne, 
    557 U.S. at 453
    . In its initial
    injunction decision, the court justified the tailored injunction
    by emphasizing the need to protect the integrity of the NEPA
    decisionmaking process. However, it did not consider this
    interest in isolation; instead, it weighed that interest against
    the need to “avoid[] . . . unnecessary delay in the delivery of a

    16
    reliable source of high quality water to approximately 81,000
    people.” J.A. 54; see also Gov’t of Manitoba v. Salazar, 
    926 F. Supp. 2d 189
    , 192 (D.D.C. 2013) (noting, in its 2013
    injunction review, that its analysis reflected an “identical”
    purpose to its 2005 decision). The completion of the FSEIS
    and ROD marks the “consummation” of the Bureau’s
    decisionmaking process regarding the Project’s primary water
    source. See Bennett v. Spear, 
    520 U.S. 154
    , 177–78 (1997).
    Appellees’ legal challenge does nothing to undermine the
    finality of the decision; for the moment, at least, the Bureau
    has come to the end of the NEPA road.
    Given this changed circumstance, we next ask whether
    North Dakota’s requested modification was suitably tailored.
    The issuance of the FSEIS and ROD significantly
    eliminated—at least temporarily—the court’s concerns about
    North Dakota’s ability to exert influence over the Bureau’s
    NEPA decisions. 10 This risk is further mitigated by North
    Dakota’s agreement to incur all costs associated with the
    proposed paper design work until the injunction is lifted “or
    the litigation is otherwise resolved.” J.A. 106. See Petties,
    
    662 F.3d at 571
     (noting the significant change in factual
    conditions inquiry should include whether the risks that led to
    injunctive relief have been “ameliorated, if not eliminated, as
    a result of changed circumstances”). On the other side of the
    scale, beneficiaries of NAWS necessarily face, at minimum, a
    four-year-long delay before North Dakota can finish
    10
    In its sur-reply to the district court, Manitoba suggested that, “[i]f
    the Bureau’s actions were a sufficient basis for modifying the
    Court’s injunction, that would also have been true at various prior
    points in this litigation as well.” J.A. 189. This is not entirely true.
    Only one of the five previous modifications occurred while a
    completed FEIS was in place. That request occurred in February
    2010, and it was granted because it was unopposed. See Appellees
    Br. 8.

    construction of the plant. With these two considerations in
    mind, we conclude North Dakota’s requested modification
    poses no current harm to the NEPA process, but it will
    forward the goal of protecting the Project’s population from
    unnecessary delay. See Nat. Res. Def. Council, Inc. v. U.S.
    Nuclear Regulatory Comm’n, 
    606 F.2d 1261
    , 1272–73 (D.C.
    Cir. 1979) (declining injunction over project construction
    despite NEPA violations after considering “the social and
    economic costs of delay” and “[t]he public interest to be
    served in the continued construction”); Alaska v. Andrus, 
    580 F.2d 465
    , 485 (D.C. Cir. 1978), vacated in part on other
    grounds sub nom., W. Oil & Gas Ass’n v. Alaska, 
    439 U.S. 922
    . Since North Dakota will fund the design work, and
    because the design work does not even involve physical
    “construction”—the term used in the original injunction—we
    conclude the modification is “suitably tailored to the changed
    circumstance.” Rufo, 
    502 U.S. at 383
    .
    In sum, the modification meets both the public interest
    and tailoring prongs of the Rule 60(b)(5) inquiry, and it
    therefore should be granted. 11
    Second, the increase in arsenic levels over the course of
    the injunction’s lifespan also constitutes a significant changed
    circumstance warranting revision of the injunction. Rufo, 
    502 U.S. at 383
    . Exposure to arsenic in drinking water has been
    linked with cancer of the skin, liver, kidney, bladder, and
    11
    Should the district court find for Manitoba and Missouri on
    summary judgment, it can ameliorate any concern that North
    Dakota’s independent expenditures will influence the ongoing
    NEPA process by specifically ordering the Bureau to disregard
    those costs.

    lung. 12 Though Minot’s water levels still fall within safe
    drinking water standards, this toxin has nearly tripled during
    the course of the injunction. Further, the community must
    wait at least four years before any treatment plant can be built,
    during which time arsenic levels may continue to rise. Given
    the narrow scope of North Dakota’s proposed design work,
    we conclude the modification serves the public interest
    because it allows the State to attempt to reduce the duration of
    these exposure risks while causing no current harm to the
    NEPA process. See Rufo, 
    502 U.S. at 381
     (noting “the public
    interest is a particularly significant reason for applying a
    flexible modification standard” where the injunction
    “reach[es] beyond the parties involved directly in the suit”);
    Petties, 
    662 F.3d at 569
    ; see also Horne, 
    557 U.S. at
    447 n.3
    (describing the potential for courts to “substantially restrict[]
    the ability of [a] State . . . to make basic decisions” as one of
    the “features and risks” of long-term injunctions). Thus, here,
    too, the modification is suitably tailored to the changed
    circumstance, and the modification should be granted.
    IV.
    We conclude North Dakota met its burden of presenting
    two significant changed circumstances that warranted
    modifying the 2005 injunction.           It also requested a
    modification suitably tailored to those circumstances. We
    therefore remand to the district court with instructions to grant
    the motion.
    In so holding, we recognize our review has benefitted
    significantly from the rectification of North Dakota’s legal
    error, as well as a more cogent presentation of its arguments.

    We are also mindful that Rule 52(a) seeks “to lighten the
    burden on the trial court” by alleviating the need for lengthy
    written opinions and extensive factual findings in the majority
    of circumstances.       See FED. R. CIV. P. 52 advisory
    committee’s note to 1983 amendment. Nevertheless, the
    district court abused its discretion by summarily accepting the
    nonmovants’ arguments. Furthermore, the relief North
    Dakota seeks is exceedingly narrow, and—at its own
    expense—it will use the modification to address an imminent
    public health crisis faced by its citizens. We find it
    appropriate under these circumstances to grant its request.
    So ordered.
