    Opinion for the Court filed by Circuit Judge KATSAS.
    KATSAS, Circuit Judge: The Department of the Interior
    sells offshore leases to oil and gas companies for development.
    This case concerns the adequacy of an environmental impact
    statement prepared in connection with two lease sales held in
    2018. We hold that Interior adequately considered the option
    of not leasing, reasonably refused to consider potential future
    regulatory changes, and unreasonably refused to consider
    possible deficiencies in environmental enforcement. Given the
    one shortcoming we have identified, we remand without
    vacatur.
    I
    A
    The Outer Continental Shelf Lands Act (OCSLA) sets
    forth a procedural framework for oil and gas development in
    the Outer Continental Shelf, an area “between the outer
    seaward reaches of a state’s jurisdiction and that of the United
    States.” Ctr. for Biological Diversity v. U.S. Dep’t of the
    Interior, 
    563 F.3d 466
    , 472 (D.C. Cir. 2009). In enacting the
    OCSLA, Congress declared that the Shelf “should be made
    available for expeditious and orderly development, subject to
    environmental safeguards.” 
    43 U.S.C. § 1332
    (3).
    *
    Circuit Judge, now Justice, Jackson was a member of the panel
    at the time the case was argued but did not participate in the opinion.
    3
    The OCSLA establishes a four-stage process for
    development. First, Interior evaluates national energy needs to
    formulate a five-year plan of proposed lease sales. 
    43 U.S.C. § 1344
    (a). Next, Interior sells the leases to the highest
    responsible qualified bidders. 
    Id.
     § 1337(a)(1). But a lease
    does not confer “an immediate or absolute right to explore for,
    develop, or produce oil or gas on the OCS; those activities
    require separate, subsequent federal authorization.” Sec’y of
    the Interior v. California, 
    464 U.S. 312
    , 317 (1984). That
    comes at the third and fourth stages, when Interior reviews
    lessees’ plans for exploration and then for development and
    production. 
    43 U.S.C. §§ 1340
    , 1351. During this process,
    Interior must prepare environmental impact statements (EISs)
    as necessary. See 
    id.
     § 1344(b)(3).
    B
    The National Environmental Policy Act governs the
    preparation of EISs.          NEPA establishes procedural
    requirements to ensure that the government gives “appropriate
    consideration” to environmental impacts before undertaking
    major actions. 
    42 U.S.C. § 4332
    (2)(B)–(C). It requires the
    government to “take a ‘hard look’ at the reasonably foreseeable
    impacts of a proposed major federal action.” Indian River
    Cnty. v. U.S. Dep’t of Transp., 
    945 F.3d 515
    , 533 (D.C. Cir.
    2019) (cleaned up). NEPA also tasks the Council on
    Environmental Quality with promulgating implementing
    regulations. 
    42 U.S.C. § 4332
    (2)(B); Dep’t of Transp. v. Pub.
    Citizen, 
    541 U.S. 752
    , 757 (2004). The statute requires that
    EISs consider “alternatives to the proposed action,” 
    42 U.S.C. § 4332
    (2)(C)(iii), and a CEQ regulation clarifies that one such
    alternative must be the possibility of taking no action, 
    40 C.F.R. § 1502.14
    (c).
    4
    An agency can “meet its NEPA obligations in steps.” W.
    Org. of Res. Councils v. Zinke, 
    892 F.3d 1234
    , 1237 (D.C. Cir.
    2018). When “tiering” its EISs, the agency first publishes a
    programmatic EIS to assess “the broad environmental
    consequences attendant upon a wide-ranging federal program.”
    
    Id.
     (cleaned up). It later issues “narrower EISs analyzing the
    incremental impacts of each specific action taken as part of a
    program.” 
    Id. at 1238
    . Supplements are required when the
    agency “makes substantial changes” to its program or “[t]here
    are significant new circumstances or information … bearing on
    the proposed action or its impacts.” 
    40 C.F.R. § 1502.9
    (d)(1).
    C
    This appeal concerns Lease Sales 250 and 251, which were
    among the 11 that Interior proposed in its five-year plan
    covering mid-2017 to mid-2022. Interior held the sales in
    2018. They involve more than 150 million acres in the Gulf of
    Mexico.
    Before the sales, Interior prepared three EISs. First, it
    issued a programmatic EIS addressing the environmental
    impacts of the five-year plan. Second, it issued a narrower
    “multisale” EIS addressing the impacts of leasing in the Gulf.
    Third, it issued a supplemental EIS specific to the two lease
    sales at issue.
    After the sales, three environmental groups asserted that
    the supplemental EIS did not comply with NEPA. They sued
    Interior and the Bureau of Ocean Energy Management
    (BOEM), the component agency within Interior that had
    prepared the EISs. They argued that BOEM failed to assess a
    true “no action” alternative because it had assumed that energy
    development would occur sooner or later, even if Lease Sales
    250 or 251 did not. They also argued that BOEM had
    unreasonably assumed two rules for protecting the
    5
    environment would remain in effect, despite the possibility of
    future modifications. Finally, they argued that BOEM had
    unreasonably assumed all such rules would be effectively
    enforced, despite a report suggesting otherwise. The American
    Petroleum Institute and Chevron U.S.A. Inc. intervened in
    support of Interior.
    The district court granted summary judgment to Interior.
    In upholding BOEM’s “no action” analysis, it found the Bureau
    had reasonably assumed that development was inevitable. Gulf
    Restoration Network v. Bernhardt, 
    456 F. Supp. 3d 81
    , 97–99
    (D.D.C. 2020). The court concluded that BOEM did not need
    to consider whether the existing rules would change. 
    Id. at 100
    .
    And it accepted BOEM’s assumption that Interior would
    adequately enforce its rules. 
    Id.
     at 100–02. The environmental
    groups now appeal.
    II
    Courts review agency compliance with NEPA through the
    Administrative Procedure Act. Sierra Club v. FERC, 
    867 F.3d 1357
    , 1367 (D.C. Cir. 2017). The district court thus sat as an
    appellate tribunal, reviewing BOEM’s decision under the
    familiar APA standards. Am. Bioscience, Inc. v. Thompson,
    
    269 F.3d 1077
    , 1083 (D.C. Cir. 2001). We, in turn, apply the
    same standards. Rempfer v. Sharfstein, 
    583 F.3d 860
    , 864–65
    (D.C. Cir. 2009).
    Under the APA, we ask whether agency action is
    “arbitrary, capricious, an abuse of discretion, or otherwise not
    in accordance with law.” 
    5 U.S.C. § 706
    (2)(A). This review
    is “highly deferential” to the agency. Defs. of Wildlife v.
    Jewell, 
    815 F.3d 1
    , 9 (D.C. Cir. 2016) (cleaned up). In
    particular, we “give deference to agency judgments as to how
    best to prepare an EIS,” Indian River Cnty., 945 F.3d at 533, so
    long as the EIS “contains sufficient discussion of the relevant
    6
    issues and opposing viewpoints” and “the agency’s decision is
    fully-informed and well-considered,” Nevada v. Dep’t of
    Energy, 
    457 F.3d 78
    , 93 (D.C. Cir. 2006) (cleaned up).
    III
    We first consider whether BOEM adequately considered a
    “no action” alternative in the supplemental EIS.
    A
    In preparing an EIS, an agency must evaluate the
    “reasonable alternatives to a contemplated action.” Food &
    Water Watch v. FERC, 
    28 F.4th 277
    , 282 (D.C. Cir. 2022)
    (cleaned up). These alternatives must include the possibility of
    taking no action. 
    40 C.F.R. § 1502.14
    (c).
    In the supplemental EIS, BOEM assessed environmental
    impacts on the assumption that future lease sales would occur
    in the Gulf even if one such sale were cancelled. Given that
    assumption, the Bureau concluded the cancellation of one
    proposed lease sale “would not significantly change the
    environmental impacts” of development in the Shelf. J.A. 904.
    This analysis was not arbitrary. Interior has a statutory
    obligation to make the Shelf available for development to meet
    national energy needs. 
    43 U.S.C. §§ 1332
    (3), 1334(a).
    Moreover, record evidence showed that the Gulf compares
    favorably to other parts of the Shelf in terms of development
    opportunities, infrastructure readiness, and industry interest.
    Thus, Interior’s five-year plan proposed that all but one of its
    lease sales would take place in the Gulf. So BOEM reasonably
    concluded that the cancellation of a single lease sale would
    only postpone development in the region.
    7
    BOEM also reasonably concluded that such a cancellation
    would not materially change overall environmental impacts. It
    explained that these impacts turn on the aggregate amount of
    leasing in the long run. A typical lease runs for 50 years, and
    BOEM projected impacts over a 70-year timeframe. At this
    scale, any single sale would make “only a small …
    contribution” to overall activity in the Shelf. J.A. 550. And a
    one- or two-year delay in development would have little effect
    on overall environmental impacts.
    B
    The environmental groups argue that BOEM failed to
    consider a true “no action” alternative because it assumed
    future lease sales would occur. They also argue that it was
    arbitrary for BOEM to predict that the postponement of a lease
    sale would not significantly affect the environment. We reject
    both arguments.
    1
    The environmental groups argue that a true “no action”
    alternative would involve the cancellation of all future planned
    leases. We agree that BOEM needed to consider that
    alternative, but we think it did. In the programmatic EIS,
    BOEM considered the effect of allowing no new leasing in the
    Gulf and even in the entire Shelf. And in the supplemental EIS,
    it incorporated that analysis by reference.
    BOEM permissibly divided its analysis across the EISs.
    Through tiering, an agency may first assess “broad
    environmental consequences” in a programmatic EIS and later
    supplement that analysis with “narrower EISs analyzing the
    incremental impacts” of specific actions. W. Org. of Res.
    Councils, 892 F.3d at 1237–38 (cleaned up). “The subsequent
    analysis need only summarize, and incorporate by reference,
    8
    the environmental issues discussed in the programmatic EIS.”
    Nevada, 457 F.3d at 91.
    The environmental groups object that such tiering would
    effectively “bind the agency to hold the lease sales as proposed
    in the five-year plan.” Reply Br. at 4. But BOEM remained
    free to reconsider its plan. It simply had no obligation to do so
    where, as here, no new information had emerged since the
    earlier EIS. 
    40 C.F.R. § 1502.9
    (d)(1)(ii).
    2
    BOEM reasonably concluded that the cancellation of a
    single lease sale would have only limited environmental
    effects. The environmental groups assert that delaying
    development might have significant effects if key variables—
    such as supply, demand, or available drilling technology—
    change over time. The Bureau acknowledged that possibility,
    but it made “educated assumptions about an uncertain future”
    and then engaged in the “reasonable forecasting” that “NEPA
    analysis necessarily involves.” Sierra Club, 867 F.3d at 1374
    (cleaned up). Specifically, BOEM estimated future production
    levels based on historical data and current industry trends. It
    predicted impacts by analyzing a range of factors and
    estimating their “frequency, duration, and geographic extent.”
    J.A. 947. And it explained the scale at which it was considering
    the impacts. Because BOEM disclosed its assumptions and
    gave reasonable analysis, its conclusion passes muster.
    IV
    We next consider whether BOEM acted arbitrarily by
    failing to consider potential changes to two environmental rules
    designed to reduce the risk of oil and gas spills.
    9
    A
    The Bureau of Safety and Environmental Enforcement
    (BSEE), another component agency within Interior, makes and
    enforces rules to reduce risks from drilling. In 2016, it adopted
    two rules at issue here. The Production Safety Rule addressed
    certain systems and devices required to ensure safe production
    of oil and gas. See 
    81 Fed. Reg. 61,834
     (Sept. 7, 2016). The
    Well Control Rule added new requirements for equipment used
    to safeguard against oil and gas blowouts. See 
    81 Fed. Reg. 25,888
     (Apr. 29, 2016).          After BOEM completed its
    supplemental EIS, BSEE revised these rules to eliminate
    “unnecessary regulatory burdens.” See 
    83 Fed. Reg. 49,216
    (Sept. 28, 2018); 
    84 Fed. Reg. 21,908
     (May 15, 2019).
    BOEM invoked the 2016 rules as it undertook its NEPA
    analysis. It concluded that they would help minimize the risk
    of future oil and gas spills. But BOEM did not consider
    whether the rules might be changed, or what impact any
    changes might have on environmental safety.          BOEM
    acknowledged the possibility of changes only in response to
    comments to the supplemental EIS. Later, after proposed
    changes began to take shape, BOEM discussed them when it
    finalized Lease Sale 251. At that point, BOEM concluded that
    the changes would not increase environmental risks because
    they left key protections intact.
    The environmental groups argue that BOEM should have
    discussed in its supplemental EIS the possibility that the 2016
    rules would be changed.
    B
    We conclude that BOEM permissibly declined to consider
    the potential rule changes, which were too inchoate to require
    discussion in the supplemental EIS.
    10
    1
    At the outset, we reject two threshold arguments raised by
    the intervenors. They contend that the environmental groups’
    criticism of the supplemental EIS amounts to a collateral attack
    on BSEE’s decision to amend the rules, which is not cognizable
    under NEPA. City of Olmsted Falls v. FAA, 
    292 F.3d 261
    , 273
    (D.C. Cir. 2002). But the groups do not challenge BSEE’s
    regulatory amendments, only BOEM’s failure to account for
    them. Because their theory “would have no effect on the
    validity” of BSEE action, they did not mount a collateral attack.
    Snoqualmie Valley Pres. Alliance v. U.S. Army Corps of
    Eng’rs, 
    683 F.3d 1155
    , 1160 (9th Cir. 2012).
    The intervenors also argue that this dispute is unripe
    because the BSEE rules have no bite until after the leasing
    stage. But we have held that a NEPA challenge is ripe once
    leases have been issued, which is when Interior’s decision “will
    result in irreversible and irretrievable commitments of
    resources to an action that will affect the environment.” Ctr.
    for Biological Diversity, 
    563 F.3d at 480
     (cleaned up). Because
    Interior has reached this point of inevitability, “it is irrelevant
    to the existence of a justiciable controversy that there will be a
    time delay before the [rules] come into effect.” Reg’l Rail
    Reorganization Act Cases, 
    419 U.S. 102
    , 143 (1974).
    2
    The district court said BOEM did not need to consider
    potential rule changes that, by definition, lacked the force of
    law. Gulf Restoration Network, 456 F. Supp. 3d at 100. We
    rest on a narrower rationale: An agency need not consider
    regulatory developments that are so inchoate as to be “not
    meaningfully possible” to analyze. Del. Riverkeeper Network
    v. FERC, 
    753 F.3d 1304
    , 1310 (D.C. Cir. 2014) (cleaned up).
    11
    In this case, BOEM finalized its supplemental EIS on
    December 5, 2017. See 
    82 Fed. Reg. 59,644
    , 59,645 (Dec. 15,
    2017). Nothing in the record suggests that it had any specific
    information about the possible rule changes at that time.
    BSEE’s earliest relevant action did not take place until
    December 6, when it completed its own draft environmental
    assessments. J.A. 1028–29. Although BSEE completed those
    assessments before BOEM published a notice of its
    supplemental EIS in the Federal Register, the relevant question
    is what BOEM knew “at the time the EIS was being prepared.”
    Habitat Educ. Ctr. v. U.S. Forest Serv., 
    609 F.3d 897
    , 898 (7th
    Cir. 2010). Nothing before us establishes that the draft
    assessments were available to BOEM before December 6—or,
    for that matter, at any point before they were published in
    connection with BSEE’s proposed regulatory changes. See 
    82 Fed. Reg. 61,703
    , 61,717 (Dec. 29, 2017); 
    83 Fed. Reg. 22,128
    ,
    22,147 (May 11, 2018).
    As of December 5, BOEM appears to have known only
    that rule changes might be forthcoming. Earlier in 2017, the
    President had ordered agencies to modify any regulations that
    burdened energy development unnecessarily, and the Secretary
    of the Interior had directed BSEE to review the Well Control
    Rule accordingly. 
    82 Fed. Reg. 16,093
     (Mar. 31, 2017); J.A.
    1079. But a general awareness that change might come is
    hardly the same as knowing its likelihood or contours. And
    NEPA does not require an agency to work through every
    “remote and speculative possibilit[y].” NRDC, Inc. v. Morton,
    
    458 F.2d 827
    , 837–838 (D.C. Cir. 1972). So BOEM
    permissibly declined to consider in its supplemental EIS the
    potential for rule changes.
    Because the environmental groups contest only what
    BOEM should have considered in its supplemental EIS, we
    need not address whether post-EIS developments, such as
    12
    publication of the proposed changes, constitute the kind of
    “significant new circumstances or information” that might
    warrant an additional EIS. 
    40 C.F.R. § 1502.9
    (d)(1)(ii). But
    we note that, before holding Lease Sale 251, BOEM explained
    its view that the proposed amendments would not undermine
    environmental safety because they left “critical safety
    provisions intact.” J.A. 1073.
    V
    We last consider whether BOEM acted arbitrarily by
    failing to address a report about deficiencies in BSEE’s
    enforcement of existing safety and environmental regulations.
    A
    BOEM repeatedly factored BSEE’s work into its analysis.
    In the programmatic EIS, it “assume[d] that BSEE would
    implement requirements for safe operations and environmental
    protection,” and it promised to “reconsider[] any related
    environmental impacts” if that assumption proved unfounded.
    J.A. 282. In the multisale EIS, it outlined BSEE’s duties and
    regulations. And in response to comments to the supplemental
    EIS, it credited what it described as BSEE’s “rigorous
    inspection program” and “rigorous enforcement programs.”
    J.A. 1021–22.
    But BOEM did not consider whether BSEE’s work was in
    fact rigorous, despite some evidence that it was not. After each
    EIS, commenters asked BOEM to address a Government
    Accountability Office report that criticized BSEE. The report
    faulted BSEE for maintaining “outdated policies and
    procedures” and failing to develop “criteria to guide how it uses
    enforcement tools.” J.A. 434, 438. It further found that this
    lack of criteria “causes BSEE to act inconsistently,” creates
    uncertainty about BSEE’s “oversight approach and
    13
    expectations,” and risks “undermining [agency] effectiveness.”
    J.A. 434, 438. After a commenter raised the report in response
    to the programmatic EIS, BOEM promised to address the
    asserted deficiencies at the leasing stage. J.A. 373. But it later
    reneged, telling commenters that the issues were outside the
    scope of the EISs at that stage. J.A. 736, 1023–24.
    B
    1
    We agree with the environmental groups that BOEM’s
    failure to address the report was arbitrary. To engage in
    reasoned decisionmaking, an agency must respond to
    “objections that on their face seem legitimate.” PPL
    Wallingford Energy LLC v. FERC, 
    419 F.3d 1194
    , 1198 (D.C.
    Cir. 2005) (cleaned up). Here, BOEM itself had repeatedly
    acknowledged the importance of BSEE enforcement to its
    analysis of environmental risks. And the GAO report, while
    hardly conclusive on this point, raised seemingly legitimate
    concerns about enforcement effectiveness.
    Of course, an agency may assume effective enforcement
    in the ordinary case. See United States v. Armstrong, 
    517 U.S. 456
    , 464 (1996) (discussing presumption of regularity). But it
    may not reach a conclusion that “runs counter to the evidence.”
    Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins. Co.,
    
    463 U.S. 29
    , 43 (1983). So, more is required when credible
    evidence seems to undercut the assumption. Here, BOEM
    sidestepped the GAO report and offered only unelaborated
    statements that BSEE’s enforcement was “rigorous.” In the
    circumstances here, that was not good enough.
    Likewise, because BOEM promised to consider the GAO
    report at the leasing stage, it should have explained its later
    decision not to do so. BOEM was of course free to change its
    14
    views, but it should have acknowledged and explained the
    change. See FCC v. Fox TV Stations, Inc., 
    556 U.S. 502
    , 515–
    16 (2009). Instead, BOEM merely brushed aside the report as
    beyond the scope of the supplemental EIS. This unexplained
    about-face was also arbitrary.
    2
    The district court discounted the GAO report because it did
    not suggest a complete lack of enforcement. Gulf Restoration
    Network, 456 F. Supp. 3d at 101. On that basis, the court
    sought to distinguish Friends of Back Bay v. U.S. Army Corps
    of Engineers, 
    681 F.3d 581
     (4th Cir. 2012), which held it
    arbitrary for the Corps to conclude that wetlands would be
    protected by a rule that was “entirely unenforced,” 
    id.
     at 588–
    89. But while Friends of Back Bay may be factually
    distinguishable, its reasoning applies here. The Fourth Circuit
    asked whether the agency had any “reasonable basis” to
    conclude that the rule “was being adequately enforced.” 
    Id. at 589
     (emphasis added). As noted above, the agency here relied
    on an assumption of effective enforcement, but it declined to
    address evidence undercutting the assumption.
    Interior further argues that BOEM did not need to address
    the report until after the leasing stage because BSEE
    enforcement does not begin until after leases are sold. But
    having invoked BSEE enforcement to argue that environmental
    concerns would be manageable, BOEM could not
    simultaneously “brush off comments” about lax enforcement
    “as beyond its purview.” Del. Dep’t of Nat. Res. & Env’t
    Control v. EPA, 
    785 F.3d 1
    , 18 (D.C. Cir. 2015). Moreover,
    we doubt that consideration of BSEE’s effectiveness can wait
    so long. Only at the early OCSLA stages does the agency
    “look[] ahead and assimilate[] broad issues relevant to the
    program” overall. Found. on Econ. Trends v. Heckler, 756
    
    15 F.2d 143
    , 159 (D.C. Cir. 1985) (cleaned up). After leases have
    issued, later EISs are “site-specific” and address “more
    particularized considerations.” 
    Id.
     (cleaned up). As with the
    issue of environmental mitigation more generally, BSEE’s
    effectiveness is not merely site-specific, and so now was the
    time to address it.
    Before this court, Interior argues that the GAO report does
    not raise significant concerns about BSEE enforcement. It
    makes at least a plausible argument on that score. But given
    everything we have discussed above, BOEM should have
    explained its position in an EIS. We cannot affirm based on a
    post hoc litigation rationalization pressed by agency counsel.
    SEC v. Chenery Corp., 
    318 U.S. 80
    , 87–88 (1943).
    VI
    Because BOEM arbitrarily declined to consider the GAO
    report, we must reverse in part the grant of summary judgment
    and remand the case for further agency consideration of that
    issue. But we decline to vacate the supplemental EIS, the
    records of decision announcing Lease Sales 250 and 251, or the
    leases issued through those sales.
    Although vacatur is the typical remedy for an APA
    violation, it is not inevitable. “The decision whether to vacate
    depends on the seriousness of the order’s deficiencies (and thus
    the extent of doubt whether the agency chose correctly) and the
    disruptive consequences of an interim change that may itself be
    changed.” Allied-Signal, Inc. v. U.S. NRC, 
    988 F.2d 146
    , 150–
    51 (D.C. Cir. 1993). Oglala Sioux Tribe v. U.S. Nuclear
    Regulatory Commission, 
    896 F.3d 520
     (D.C. Cir. 2018), is
    instructive on the appropriateness of remand without vacatur in
    the NEPA context. There, we recognized the “seriousness” of
    the “deficiencies” in the EIS under review. 
    Id. at 538
    . But we
    declined to vacate either the EIS or an associated mining
    16
    license because we had “not been given any reason to expect
    that the agency [would] be unable to correct those deficiencies”
    on remand, and we were concerned about the disruptive effects
    of vacating the license in the interim. 
    Id.
     In addition, we
    concluded that the challenger would “not suffer harm—
    irreparable or otherwise” from leaving the license in effect at
    least for awhile longer. See 
    id.
    The same considerations are present here. Whatever the
    seriousness of BOEM’s error, its attorneys make a colorable
    case that the GAO report ultimately should not change the
    bottom line. While we cannot affirm on that basis, we can say
    that the environmental groups have given us no reason to doubt
    that BOEM itself can make the same case on remand.
    Moreover, vacatur would be highly disruptive for the lessees.
    They have paid millions of dollars to obtain their leases and
    have acted for some four years in reliance on them—including
    by investing substantial additional sums and by executing
    contracts with third parties. Moreover, any redo of the lease
    sales “would be tainted by prior publication of [the] lessees’
    proprietary valuation of the leases” following the original sales.
    Intervenors’ Br. at 33. Conversely, the environmental groups
    have identified no harm that flows from leaving the sales in
    place for now, when exploration and development cannot occur
    absent further regulatory approvals from Interior.
    We also decline to grant an intermediate remedy between
    vacatur and remand without vacatur. The environmental
    groups propose that we at least enjoin activity under Lease
    Sales 250 and 251. We have occasionally ordered this kind of
    partial relief in NEPA cases. See, e.g., Pub. Emps. for Env’t
    Responsibility v. Hopper, 
    827 F.3d 1077
    , 1084 (D.C. Cir. 2016)
    (declining to vacate a lease or regulatory approvals but
    vacating an EIS and imposing conditions on the lessee’s
    activity). But we see no reason to grant such relief here. The
    17
    deficiency in the supplemental EIS seems correctable, and even
    partial relief would be disruptive, as the lessees risk forfeiting
    their leases if they cannot timely meet certain obligations.
    VII
    We reverse the summary judgment in part and remand the
    case to the district court with instructions to remand it to the
    agency for further consideration of the GAO report. In so
    doing, we decline to vacate any of the administrative orders
    under review. We affirm the summary judgment in all other
    respects.
    So ordered.
