    SUMMARY*
    Environmental Law
    The panel reversed the district court’s summary judgment
    entered in favor of federal defendants in an action challenging
    the government’s environmental impact statements analyzing
    the environmental effects of proposed leases for oil and gas
    development in the Chukchi Sea off the northwest coast of
    Alaska.
    The panel held that the Final Environmental Impact
    Statement and Supplemental Environmental Impact
    Statement prepared by the federal defendants properly took
    account of incomplete or unavailable information. The panel
    held, however, that the reliance in the Final Environmental
    Impact Statement on a one billion barrel estimate of total
    economically recoverable oil was arbitrary and capricious.
    The panel remanded for further proceedings.
    Judge Rawlinson concurred in part and dissented in part.
    Judge Rawlinson agreed with most of the majority opinion,
    but she did not agree that the federal Bureau of Ocean Energy
    Management, Regulation and Enforcement acted arbitrarily
    in selecting one billion barrels of oil as the benchmark for
    analyzing the environmental affects of the proposed leases.

    OPINION
    W. FLETCHER, Circuit Judge:
    The Bureau of Ocean Energy Management (“BOEM”)1 of
    the Department of the Interior has sought to lease “excellent
    prospects” for oil and gas development in the Chukchi Sea off
    the northwest coast of Alaska. The parcels available for lease
    are cumulatively known as Lease Sale 193. Pursuant to the
    National Environmental Policy Act (“NEPA”), BOEM
    prepared a Final Environmental Impact Statement (“FEIS”)
    analyzing the environmental effects of the proposed leases.
    1
    Earlier incarnations of the agency have been the Minerals Management
    Service and the Bureau of Ocean Energy Management, Regulation and
    Enforcement. For simplicity, we refer to the agency, including its earlier
    incarnations, as BOEM.
    NATIVE VILLAGE OF POINT HOPE V. JEWELL               5
    BOEM based its environmental analysis on the assumption
    that if oil development actually occurs, one billion barrels of
    oil will be economically recoverable.
    Plaintiffs argued in the district court that BOEM abused
    its discretion by failing to account for essential missing
    information in the FEIS. Plaintiffs also argued that BOEM’s
    estimate of one billion barrels is arbitrary and capricious.
    They contended that the potential economically recoverable
    oil from the lease sale is far higher than one billion barrels,
    and that BOEM had not given an adequate explanation for
    using its lower estimate. The district court initially rejected
    the FEIS for failing to account for the missing information.
    After remand, BOEM prepared a Supplemental EIS (“SEIS”)
    addressing the missing information. Based on the FEIS and
    SEIS, the district court granted summary judgment to
    defendants.
    We largely agree with the district court that the agency
    did not abuse its discretion in its analysis of the missing
    information. However, we agree with plaintiffs that the
    agency’s estimate of one billion barrels was chosen
    arbitrarily, and that this arbitrary decision meant that the
    agency based its decision on inadequate information about the
    amount of oil to be produced pursuant to the lease sale.
    I. Background
    The Chukchi Sea is a southern arm of the Arctic Ocean
    between Alaska and Russia. The Sea contains a wide variety
    of animals, including bowhead whales, polar bears, pacific
    walrus, seals, fish, and birds. Some of these animals provide
    subsistence for native Inupiat communities along the Alaskan
    coast. Some of the animals are listed under the Endangered
    6       NATIVE VILLAGE OF POINT HOPE V. JEWELL
    Species Act (“ESA”) as endangered or threatened. Five
    exploratory wells were drilled in the Sea between 1989 and
    1991. They had “positive shows” but did not lead to
    commercial production.
    The Outer Continental Shelf Lands Act (“OCSLA”)
    prescribes four steps the federal government must take in
    order to pursue offshore oil and gas development: “‘(1)
    formulation of a five year leasing plan by the Department of
    the Interior; (2) lease sales; (3) exploration by the lessees;
    [and] (4) development and production.’” Edwardsen v. U.S.
    Dep’t of the Interior, 
    268 F.3d 781
    , 784 (9th Cir. 2001)
    (quoting Sec’y of the Interior v. California, 
    464 U.S. 312
    , 337
    (1984)). At the “lease sale” stage, the Secretary of the
    Interior selects the parcels that will be offered for lease,
    accepts bids from parties, and collects funds from parties with
    winning bids. The Department of the Interior must review
    and approve specific exploration and development plans
    before winning bidders can “proceed with full exploration,
    development, or production” of oil or gas. Sec’y of the
    Interior, 
    464 U.S. at 339
    . However, successful bidders have
    the right to undertake “ancillary activities” in the field such
    as geological and geophysical surveys and studies that
    “model potential oil and hazardous substance spills.” 
    30 C.F.R. § 550.207
    .
    A. NEPA
    NEPA “protect[s] the environment by requiring that
    federal agencies carefully weigh environmental
    considerations and consider potential alternatives to the
    proposed action before the government launches any major
    federal action.” Barnes v. U.S. Dep’t of Transp., 
    655 F.3d 1124
    , 1131 (9th Cir. 2011) (internal quotation marks
    NATIVE VILLAGE OF POINT HOPE V. JEWELL              7
    omitted). “‘NEPA imposes procedural requirements designed
    to force agencies to take a “hard look” at environmental
    consequences’” of major federal action. 
    Id.
     (quoting Earth
    Island Inst. v. U.S. Forest Serv., 
    351 F.3d 1291
    , 1300 (9th
    Cir. 2003)). The statute requires federal agencies to
    “consider every significant aspect of the environmental
    impact of a proposed action” and to “inform the public that
    [they] ha[ve] indeed considered environmental concerns in
    [their] decisionmaking process.” Balt. Gas & Elec. Co. v.
    Natural Res. Def. Council, Inc., 
    462 U.S. 87
    , 97 (1983)
    (internal quotation marks omitted).
    NEPA requires that federal agencies prepare an EIS for
    any “major Federal actions significantly affecting the quality
    of the human environment.” 
    42 U.S.C. § 4332
    (2)(C). An
    agency must consider:
    (i) the environmental impact of the proposed
    action,
    (ii) any adverse environmental effects which
    cannot be avoided should the proposal be
    implemented,
    (iii) alternatives to the proposed action,
    (iv) the relationship between local short-term
    uses of man’s environment and the
    maintenance and enhancement of long-term
    productivity, and
    (v) any irreversible and irretrievable
    commitments of resources which would be
    8       NATIVE VILLAGE OF POINT HOPE V. JEWELL
    involved in the proposed action should it be
    implemented.
    
    Id.
     An agency must take into account all “reasonably
    foreseeable significant adverse effects” of the proposed action
    in its analysis of environmental effects. 
    40 C.F.R. § 1502.22
    ;
    see also 
    id.
     § 1508.7. NEPA also requires an agency to
    analyze missing and incomplete information. As we explain
    in greater detail below, an agency must either obtain
    information that is “essential to a reasoned choice among
    alternatives” or explain why such information was too costly
    or difficult to obtain. Id. § 1502.22.
    An agency is required to comply with NEPA at various
    stages of the oil and gas development process. An agency is
    not required at the lease sale stage to analyze potential
    environmental effects on a site-specific level of detail. N.
    Alaska Envtl. Ctr. v. Kempthorne, 
    457 F.3d 969
    , 975–76 (9th
    Cir. 2006). To some degree, lease sale analyses may be based
    on information that is uncertain or missing at the time of the
    sale when that information can be obtained at a “later stage[]
    of the exploration process.” Tribal Vill. of Akutan v. Hodel,
    
    869 F.2d 1185
    , 1192 (9th Cir. 1988). At the same time, the
    agency cannot shirk its responsibility to “consider[] all
    foreseeable direct and indirect impacts” of the proposed
    action in its EIS. N. Alaska Envtl. Ctr., 457 F.3d at 975
    (internal quotation marks omitted). The agency also must
    “discuss[] . . . adverse impacts” without “improperly
    minimiz[ing] negative side effects.” Id.
    B. Lease Sale 193
    After completing a five-year leasing plan for the Chukchi
    Sea, BOEM decided to offer a large portion of the Sea for oil
    NATIVE VILLAGE OF POINT HOPE V. JEWELL                 9
    and gas leasing. The FEIS analyzed four alternatives for the
    lease sale: (1) a 34-million acre proposed lease option
    covering 6,156 blocks of the Chukchi Sea; (2) a no-lease
    option; (3) a proposed lease option excluding 1,765 blocks
    extending along a corridor about 60 miles from the Alaskan
    coast; and (4) a proposed lease option excluding 795 blocks
    extending along a corridor between 25 and 50 miles from the
    Alaskan coast.
    The National Marine Fisheries Service recommended that
    the Secretary of the Interior select the third alternative, under
    which development would be farther from the coast, based on
    its conclusion that numerous endangered and threatened
    species living close to shore would be adversely affected by
    oil development. The Secretary of the Interior accepted
    BOEM’s recommendation and selected the fourth alternative,
    under which development would be closer to the coast.
    The lease sale occurred on February 6, 2008. The federal
    government collected over $2.6 billion from the winning
    bidders. At the time of the lease sale, there were no active
    leases in the Sea.
    C. Procedural History
    Plaintiffs filed suit, alleging seven deficiencies in the
    FEIS:
    1. [The FEIS] does not adequately analyze
    and present the impacts of Lease Sale 193 on
    the environment and human communities;
    2. [It] fails to include essential missing
    information about the Chukchi Sea and the
    10      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    potential impacts of the lease sale, or explain
    why excluding this information is justified;
    3. [It] fails to adequately analyze the impact
    of the lease sale in the context of a warming
    climate;
    4. [It] understates the potential impacts of oil
    and gas development pursuant to the leases by
    analyzing a limited development scenario;
    5. [It] understates the risks of an oil spill;
    6. [It] fails to fully analyze the cumulative
    impacts to threatened eiders of the lease sale
    and other oil and gas development in
    threatened eiders’ Arctic habitat; and
    7. [It] provides a misleading analysis of the
    effects of seismic surveying.
    The parties cross-moved for summary judgment.
    The district court agreed with defendants that much of the
    FEIS complied with NEPA, including the FEIS’s assumption
    that there would be one billion barrels of economically
    recoverable oil. However, the court concluded that the
    FEIS’s analysis was flawed in three respects: it “failed to
    analyze the environmental impact of natural gas development,
    despite industry interest and specific lease incentives for such
    development”; it “failed to determine whether missing
    information identified by the agency was relevant or essential
    under 40 C.F.R § 1502.22”; and it “failed to determine
    whether the cost of obtaining the missing information was
    NATIVE VILLAGE OF POINT HOPE V. JEWELL              11
    exorbitant, or the means of doing so unknown.” The district
    court granted in part plaintiffs’ motion for summary
    judgment, issued a limited injunction, and remanded to
    BOEM for further proceedings.
    After remand from the district court, BOEM prepared an
    SEIS. The SEIS analyzed the consequences of natural gas
    exploration and production. In the aftermath of the
    Deepwater Horizon oil spill in the Gulf Coast, it also
    analyzed the environmental impacts of a very large oil spill.
    Finally, BOEM prepared an appendix analyzing “whether the
    information gaps that were identified in the Sale 193 FEIS
    were relevant and necessary to evaluate reasonably
    foreseeable significant adverse effects.” Based on the FEIS,
    now supplemented by the SEIS, the Secretary of Interior
    again chose the fourth alternative for oil and gas leasing.
    Based on the FEIS and SEIS, the district court granted
    BOEM’s motion for summary judgment. The court found
    that “BOEM has identified missing or incomplete information
    and has adequately evaluated it in a manner that is clearly
    sufficient at this stage of the development process to satisfy
    the requirements of 
    40 C.F.R. § 1502.22
    .” The court gave
    “considerable deference . . . to BOEM’s expertise.” Plaintiffs
    timely appealed.
    II. Standard of Review
    Our review of an EIS is governed by the Administrative
    Procedure Act (“APA”). “Under the APA, we may set aside
    an agency decision if it is ‘arbitrary, capricious, an abuse of
    discretion, or otherwise not in accordance with law.’” Native
    Ecosystems Council v. U.S. Forest Serv., 
    428 F.3d 1233
    , 1238
    (9th Cir. 2005) (quoting 
    5 U.S.C. § 706
    (2)(A)). “Review
    12      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    under the arbitrary and capricious standard is narrow, and we
    do not substitute our judgment for that of the agency.” Lands
    Council v. McNair (Lands Council II), 
    537 F.3d 981
    , 987 (9th
    Cir. 2008) (en banc) (alterations and internal quotation marks
    omitted). However, an agency’s decision can be set aside if:
    the agency relied on factors Congress did not
    intend it to consider, entirely failed to
    consider an important aspect of the problem,
    or offered an explanation that runs counter to
    the evidence before the agency or is so
    implausible that it could not be ascribed to a
    difference in view or the product of agency
    expertise.
    
    Id.
     (internal quotation marks omitted). Such actions would be
    “clear error[s] of judgment that would render [the agency’s]
    action arbitrary and capricious.” 
    Id. at 993
     (internal quotation
    marks omitted).
    We “may affirm a summary judgment only if, viewing the
    evidence in the light most favorable to the party against
    whom it is granted, we find no genuine issue of material fact,
    and we find that the prevailing party is clearly entitled to
    judgment as a matter of law.” California v. Watt, 
    683 F.2d 1253
    , 1258 (9th Cir. 1982), rev’d on other grounds sub nom.
    Sec’y of the Interior v. California, 
    464 U.S. 312
     (1984).
    III. Discussion
    On appeal, plaintiffs argue that BOEM abused its
    discretion in two respects. First, they argue that “essential”
    information is missing from the FEIS and SEIS, in violation
    of 
    40 C.F.R. § 1502.22
    . Second, they argue that the FEIS and
    NATIVE VILLAGE OF POINT HOPE V. JEWELL              13
    SEIS underestimate the adverse environmental impact of the
    lease sale because they use an unrealistically low estimate of
    the economically recoverable oil. We disagree with
    plaintiffs’ first argument, but agree with their second
    argument.
    A. Essential Information
    An agency’s obligation with respect to incomplete or
    unavailable information is spelled out in 
    40 C.F.R. § 1502.22
    .
    The agency “shall always make clear that . . . information is
    lacking.” 
    Id.
     If the missing information is “relevant to
    reasonably foreseeable significant adverse impacts” and is
    “essential to a reasoned choice among alternatives and the
    overall costs of obtaining it are not exorbitant,” the agency
    must include that information in the EIS. 
    Id.
     § 1502.22(a).
    If the missing information “cannot be obtained because the
    overall costs of obtaining it are exorbitant or the means to
    obtain it are not known,” the agency must include the
    following in the EIS: (1) a statement that such information is
    “incomplete or unavailable”; (2) a statement of the “relevance
    of the incomplete or unavailable information to evaluating
    reasonably foreseeable significant adverse impacts on the
    human environment”; (3) a “summary of existing credible
    scientific evidence . . . relevant to evaluating the reasonably
    foreseeable adverse impacts”; and (4) the agency’s
    “evaluation of such impacts based upon theoretical
    approaches or research methods generally accepted in the
    scientific community.” Id. § 1502.22(b). Section 1502.22(b)
    clarifies that reasonably foreseeable effects “include[]
    impacts which have catastrophic consequences, even if their
    probability of occurrence is low.”
    14      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    Much of the information missing from the EIS concerns
    animal populations potentially affected by oil exploration and
    production under the leases. The missing information
    concerns such things as population levels of various species
    of animals in the Chukchi Sea, including endangered or
    threatened animals; the locations of various animal
    populations during the year; the feeding and breeding habits
    of various animal populations; and the vulnerability of
    various animal populations to drilling and other exploration
    and production-related activities.
    With respect to the potential environmental harm from a
    large oil spill, BOEM concluded that the missing information
    was not essential to a reasoned choice among the alternatives.
    It wrote in the SEIS, “[I]n the unlikely event of a large oil
    spill, it is well-understood that environmental impacts could
    be severe. The severity of potential impacts would be nearly
    identical under any action alternative; therefore, very specific
    types of information relevant to species, particular life history
    traits, or behavior do not help substantially in distinguishing
    among alternatives.” With respect to other activities or
    events with potential adverse impacts on the animal
    populations in the Chukchi Sea, BOEM concluded that
    sufficient protections would be provided by the requirements
    of other environmental statutes, such as the Clean Air Act, the
    Marine Mammal Protection Act (“MMPA”), and the ESA,
    and by the requirement under NEPA to provide site-specific
    analyses at later stages of development.
    Based on these conclusions, BOEM stated in the SEIS
    that it did not consider any of the incomplete or unavailable
    information at issue to be “essential to a reasoned choice
    among alternatives” at this stage of the development process.
    
    40 C.F.R. § 1502.22
    (a). BOEM therefore did not determine
    NATIVE VILLAGE OF POINT HOPE V. JEWELL              15
    whether the information was unobtainable “because the
    overall costs of obtaining it are exorbitant or the means to
    obtain it are not known.” 
    Id.
     § 1502.22(b). Nor did BOEM
    go through the steps required by § 1502.22(b) if it had found
    “essential” information to be unobtainable. Instead, BOEM
    specifically relied in the SEIS on what it characterized as its
    “understanding that certain items of presently missing or
    incomplete information will be known (and utilized to avoid
    or minimize adverse impacts) at a later stage of OCS Lands
    Act environmental review.” BOEM promised in the SEIS
    that it “would thoroughly review specific development &
    production plans at Step 4 [‘development and production’],
    if and when a project proponent actually submits a plan.
    Thus, while certain information may, in fact, be essential at
    a later stage of OCS Lands Act [review], such information
    may not be essential to a reasoned choice among alternatives
    at this lease sale stage.”
    In Village of False Pass v. Clark, 
    733 F.2d 605
     (9th Cir.
    1984), we reviewed an EIS of an oil and gas lease sale under
    OCSLA. The plaintiff had argued that the commitment made
    by the government when entering into leases under OCSLA
    is so substantial that a fully exhaustive environmental
    analysis under NEPA had to be performed at the lease sale
    stage. We disagreed, writing:
    NEPA may require an environmental impact
    statement at each stage: leasing, exploration,
    and production and development.
    Furthermore, each stage remains separate.
    The completion of one stage does not entitle
    a lessee to begin the next.
    16      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    
    Id. at 614
    . We wrote to the same effect in Northern Alaska
    Environmental Center:
    [P]rojects [for the development of oil and gas
    natural resources] generally entail separate
    stages of leasing, exploration and
    development. At the earliest stage, the leasing
    stage we have before us, there is no way of
    knowing what plans for development, if any,
    may eventually materialize.
    457 F.3d at 977.
    A lease sale under OCSLA is analogous to a
    “programmatic” plan. The required level of analysis in an
    EIS is different for programmatic and site-specific plans. We
    wrote in Friends of Yosemite Valley v. Norton, 
    348 F.3d 789
    (9th Cir. 2003):
    An agency’s planning and management
    decisions may occur at two distinct
    administrative levels:
    (1) the “programmatic level” at which
    the [agency] develops alternative
    management scenarios responsive to
    public concerns, analyzes the costs,
    benefits and consequences of each
    alternative in an [EIS], and adopts an
    amendable [management] plan to guide
    management of multiple use resources;
    and (2) the implementation stage during
    which individual site specific projects,
    NATIVE VILLAGE OF POINT HOPE V. JEWELL           17
    consistent with the [management] plan,
    are proposed and assessed.

    Serv., 
    192 F.3d 922
    , 923, [n.2] (9th Cir.
    1999). An EIS for a programmatic plan . . .
    must provide ‘sufficient detail to foster
    informed decision-making,’ but ‘site-specific
    impacts need not be fully evaluated until a
    critical decision has been made to act on site

    Regardless of whether a programmatic or site-specific
    plan is at issue, NEPA requires that an EIS analyze
    environmental consequences of a proposed plan as soon as it
    is “reasonably possible” to do so. We wrote in Kern v. U.S.
    Bureau of Land Management, 
    284 F.3d 1062
     (9th Cir. 2002),
    with respect to a programmatic plan:
    Once an agency has an obligation to
    prepare an EIS, the scope of its analysis of
    environmental consequences in that EIS must
    be appropriate to the action in question.
    NEPA is not designed to postpone analysis of
    an environmental consequence to the last
    possible moment. Rather, it is designed to
    require such analysis as soon as it can
    reasonably be done. If it is reasonably
    possible to analyze the environmental
    consequences in an EIS for [a Resource
    18       NATIVE VILLAGE OF POINT HOPE V. JEWELL
    Management Plan], the agency is required to
    perform that analysis.

    133 S. Ct. 2843
     (2013). This is not
    to say that an agency must provide the most extensive
    environmental analysis possible at the earliest possible
    moment, for an agency has some flexibility in deciding the
    level of analysis to be performed at a particular stage. We
    will defer to the agency’s judgment about the appropriate
    level of analysis so long as the EIS provides as much
    environmental analysis as is reasonably possible under the
    circumstances, thereby “provid[ing] sufficient detail to foster
    informed decision-making” at the stage in question. Friends
    of Yosemite Valley, 348 F.3d at 800 (internal quotation marks
    omitted).
    In the case before us, we conclude that BOEM has
    reasonably concluded that the missing information from the
    FEIS and SEIS is not “essential” to informed decisionmaking
    at the lease sale stage. We agree with BOEM that compliance
    with statutes such as the MMPA and the ESA will provide
    protection for animals covered by those statutes. The MMPA
    generally prohibits the “take” of marine mammals. 
    16 U.S.C. § 1371
    (a). A “take” encompasses any act of “torment” or
    “annoyance” that “has the potential to injure . . . or . . . disturb
    a marine mammal or marine mammal stock in the wild by
    causing disruption of natural behavioral patterns, including,
    but not limited to, migration, surfacing, nursing, breeding,
    feeding, or sheltering.”

     § 1362(13), (18)(A)(i)–(ii).
    Unlawful “takes” trigger civil and criminal penalties. Id.
    § 1375(a)(1), (b). Further, under the ESA § 7(a)(2),
    
    16 U.S.C. § 1536
    (a)(2), BOEM must consult with the
    NATIVE VILLAGE OF POINT HOPE V. JEWELL              19
    National Marine Fisheries Service and the U.S. Fish and
    Wildlife Service to “insure that any action authorized, funded,
    or carried out by such agency . . . is not likely to jeopardize
    the continued existence of any endangered species or
    threatened species.” If an action is likely to jeopardize a
    species, the acting agency must determine whether any
    “reasonable and prudent alternatives” exist that will avoid
    jeopardizing that species. 
    16 U.S.C. § 1536
    (b)(3)(A). We
    recognize that BOEM has already consulted with these
    agencies at the lease sale stage. It may well have to consult
    with them again at the development and production stage
    when specific plans have been proposed and site-specific
    activities are contemplated. (We note that it may also have to
    consult again at the lease sale stage, once it has performed a
    proper analysis of the estimated overall oil production.)
    Because these statutes provide additional protections for
    animals in the Chukchi Sea, they support BOEM’s conclusion
    that missing information about these animals was not
    “essential” at this stage.
    We also agree with BOEM that further environmental
    analysis will be appropriate at a later stage. In BOEM’s
    words, “certain items of presently missing or incomplete
    information will be known (and utilized to avoid or minimize
    adverse impacts) at a later stage of OCS Lands Act
    environmental review.” That is, “when a project proponent
    actually submits a plan,” BOEM will be required under
    NEPA to perform a plan- or site-specific environmental
    analysis of that proposed plan. At that stage, missing or
    incomplete information that has not been “essential to a
    reasoned choice among alternatives” at the lease sale stage
    may later become essential.        If there is “essential”
    information at the plan- or site-specific development and
    production stage, BOEM will be required to perform the
    20      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    analysis under § 1502.22(b) that it has not performed in the
    FEIS and SEIS now before us.
    Of course, we recognize that our discussion and decision
    in the next Section regarding BOEM’s one billion barrel
    estimate may have some effects upon the remainder of the
    FEIS. But we will not at this time speculate about the extent
    of those effects, if any. The Defendants are in the best
    position to analyze those effects, if any, and have the duty to
    analyze them in the first instance.
    B. One Billion Barrel Estimate
    Plaintiffs contend that BOEM chose an arbitrary number
    for the total barrels of economically recoverable oil from
    Lease Sale 193. The FEIS estimated the amount of
    recoverable oil by estimating production from the “first
    offshore oil field” that would be developed within the area of
    the leases. BOEM did not make any estimate of recoverable
    oil from additional fields that might be developed. The FEIS
    specified that the “recoverable oil resources from this field
    are assumed to be 1 billion barrels (Bbbl).” The FEIS then
    used the one billion barrel estimate as the basis for its
    environmental analysis.
    We must determine whether BOEM has articulated a
    rational basis for its decision to use the one billion barrel
    estimate. Mora-Meraz v. Thomas, 
    601 F.3d 933
    , 939 (9th
    Cir. 2010). We must reverse a decision as arbitrary and
    capricious if
    the agency relied on factors Congress did not
    intend it to consider, entirely failed to
    consider an important aspect of the problem,
    NATIVE VILLAGE OF POINT HOPE V. JEWELL               21
    or offered an explanation that runs counter to
    the evidence before the agency or is so
    implausible that it could not be ascribed to a
    difference in view or the product of agency
    expertise.
    Lands Council II, 
    537 F.3d at 987
     (internal quotation marks
    omitted). For the reasons that follow, we conclude that
    BOEM’s one billion barrel estimate is arbitrary and
    capricious.
    1. The Selection of One Billion Barrels
    BOEM first announced it was developing an EIS in
    preparation for Lease Sale 193 in July 2005. According to
    internal BOEM emails, BOEM analyst Jim Craig was
    assigned to provide “resource estimates and a scenario”
    which other BOEM scientists would use to analyze
    environmental effects. Craig emailed his supervisor, Deborah
    Cranswick, stating that he believed that “[t]he reasonably
    foreseeable scenario” should include “oil production from the
    first field only, not the full economic potential.” Craig’s
    reason for focusing on the first field production was practical;
    he would have to wait for about two months to have
    information that would allow him to develop a scenario for
    the entire area covered by the lease sale. Craig stated in his
    email, “You realize that we won’t have the 2005 resource
    assessment numbers until Sept, so we must base the scenario
    on the ‘first development’ not the total economic potential.”
    Craig also indicated that this emphasis on the first oil field
    was a “departure from previous work.”
    Craig asked Cranswick whether the scenario should
    employ a single estimate of oil production from that first
    22      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    field, or whether it should employ a range. Cranswick
    responded by email that she preferred a range. Craig then
    suggested, in a July 29 email, a range from 500 million
    barrels to 1.5 billion barrels. Craig emphasized in his email
    that the scenario should assume “equal probability for any
    volume within the range” so that one billion barrels “does not
    become the de facto most-likely” outcome. Craig’s draft
    scenario also noted, with respect to recoverable oil in the
    Chukchi Sea, that “[o]ur current petroleum assessment
    indicates that recoverable oil resources could range from 3.6
    to 11.8 billion barrels.”
    There is a gap in the email chain in our record, so we do
    not know Cranswick’s next response to Craig. But we do
    know that in a subsequent email from Craig to Cranswick on
    August 2, Craig proposed a single one billion barrel estimate
    as an alternative to using a range that was “too broad”:
    Attached is a table with E&D data. If this
    represents too broad of a range, then I think
    we should fall back to a single volume (1.0
    Bbbl) for the EIS analysis with a
    corresponding set of single E&D numbers.
    It’s hard to have it both ways (very narrow
    range) when these figures are entirely
    speculative.
    There are two clear options:
    1) 500-1500 MMbbl, as a uniform
    distribution (every point in range is
    equally likely). This will require a low and
    high case analysis.
    NATIVE VILLAGE OF POINT HOPE V. JEWELL            23
    2) 1.0 Bbbl as a single point estimate with
    no confidence interval. This will require
    a mostly likely case analysis only.
    Although it would be nice to propose a
    recoverable oil volume of 932 MMbbl +/- 134
    MMbbl in a 90% confidence interval, we
    don’t have any data to support it.
    Pick (1) or (2), but not (1) and (2).
    On August 3, Cranswick emailed Craig a data chart reflecting
    Craig’s second option. It contained only a single one billion
    barrel estimate.
    On that same day, Craig emailed to Cranswick a draft
    scenario relying on the one billion barrel estimate of oil
    production. This draft explained:
    The scenario assumed for environmental
    analysis involves the discovery, development,
    and production of the first oil field in the
    Chukchi sale area. Ultimately recoverable oil
    resources from this field are assumed to be 1
    billion barrels (Bbbl). Smaller oil volumes are
    not likely to be economic to produce and
    single pools containing larger volumes are
    increasingly rare. If oil prices drop below
    $30.00 per barrel (they are above $50.00
    when this scenario was written), exploration
    in the Chukchi OCS is expected to be minimal
    and oil discoveries may not be developed.
    24      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    The draft also pointed out that “the mean recoverable oil
    resource [in the Chukchi Sea] is 12 Bbbl with a 5%
    probability of 29 Bbbl.” Craig also prepared a chart for
    Cranswick comparing the numbers Craig had selected for the
    Lease Sale 193 EIS to an EIS prepared for the Chukchi Sea
    and Hope Sea Basin for the 2002–2007 Five Year Oil and
    Gas Leasing Program. That previous EIS had estimated a
    range for economical oil production from 0.96 billion barrels
    to 2.42 billion barrels.
    On August 10, Cranswick circulated the Lease Sale 193
    EIS scenario to other BOEM scientists who would be
    working on the EIS. The scenario contained the one billion
    barrel estimate. Cranswick explained in an email that
    [t]he scenario is based on a one mid-range
    economic resource number (note - this is not
    necessarily the most likely. A lower volume is
    more likely to occur but less likely to be
    developed from an economic standpoint; a
    higher volume is less likely to occur but more
    likely to be developed).
    Several BOEM employees expressed concern with the
    agency’s proposed scenario. For example, one NEPA analyst
    employed by BOEM, Dee Williams, wrote, “I don’t
    understand why [the agency] doesn’t use their sophisticated
    assessment indices to impose a more definitive likely
    scenario. Clearly, it is impossible to predict ‘with certainty’,
    but the narrative needs to inspire greater public confidence by
    explaining the parameters of reasonable expectations.”
    Williams further stated:
    NATIVE VILLAGE OF POINT HOPE V. JEWELL                 25
    If it becomes economical to build one
    platform to produce an estimated 1 billion
    barrels, and there is between 12 and 29 billion
    barrels that are recoverable, why is the
    scenario not compelled to imagine more than
    one platform (i.e. is a single platform always
    the initial scenario, in which case maybe we
    should just explain that)?
    Cranswick responded that “the initial scenario is one platform
    because we can’t have only a partial platform if that is all that
    the resource estimate support[s].” At the same time,
    Cranswick suggested that smaller oil developments would be
    associated with the first oil platform. “Once the first platform
    goes in, it is likely that additional satellite subsea completions
    would be developed before another host platform would be
    considered.”
    Once the draft EIS was completed, BOEM sought
    comments from other agencies and from the public.
    Numerous outside commentators expressed concern about the
    scenario BOEM had developed.         For example, the
    Environmental Protection Agency wrote that
    the hypothetical development scenario that is
    used in the document add[s] additional layers
    of uncertainty regarding the probabilities of
    exploration, production and development
    activities and the risks associated with those
    activities. . . . EPA is concerned that, overall,
    the depth and diversity of uncertainties
    presented in the document resulted in the lack
    of adequate support for many of the
    document’s conclusions.
    26      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    The Division of Migratory Bird Management at the U.S. Fish
    and Wildlife Service (“FWS”) similarly challenged the one
    billion barrel estimate as inaccurate:
    The basic assumptions used in the analysis of
    effects are flawed with regards to the size of
    development scenarios. The [Draft EIS
    (“DEIS”)] states that the current petroleum
    assessment indicates a mean recoverable oil
    resource of 12 billion barrels; yet all
    environmental analyses reported in the DEIS
    are based on a development of 1 billion
    barrels, thereby significantly underestimating
    likely scenarios.
    The Division recommended that BOEM not proceed with the
    lease sale until problems with the EIS were corrected. Public
    commentators similarly pointed to flaws in employing a one
    billion barrel production estimate, including that such an
    estimate was “based on a price of oil at half the current
    market value,” that the estimate “severely understates the true
    cumulative impacts” of oil production, and that it was
    “nowhere . . . justified with scientific analysis.” Despite these
    criticisms, BOEM continued to rely on its one billion barrel
    estimate. The one billion barrel estimate was the basis for the
    entire FEIS, including its analysis of the risk of a large oil
    spill. For example, BOEM instructed the FWS to rely on that
    estimate in that agency’s analysis of whether the lease sale
    would jeopardize listed threatened species such as the
    spectacled and Steller’s eiders. Had FWS made a jeopardy
    finding, BOEM either would not have been able to proceed
    with the Lease Sale under the ESA or would have had to
    obtain an exemption from the “no jeopardy” rule.

    (a)(2).
    NATIVE VILLAGE OF POINT HOPE V. JEWELL               27
    2. Arbitrary and Capricious
    Plaintiffs contend that the one billion barrel estimate was
    chosen arbitrarily, and that BOEM did not provide an
    adequate explanation for its selection. We agree for three
    reasons.
    First, BOEM has not justified its choice of the lowest
    possible amount of oil that was economical to produce as the
    basis for its analysis. The draft EIS scenario stated that the
    agency chose to focus on a one billion barrel estimate in part
    because any volume lower than one billion barrels would not
    be economical to produce. At the same time, BOEM was
    well aware that if any oil was produced from Lease Sale 193,
    the economically recoverable oil was very likely to exceed
    one billion barrels. In an August 18, 2005, email
    commenting on the in-progress draft EIS, Jim Craig wrote,
    “We assume 1 billion bbl for the first field, but there is
    another 11 Bbbl that is economic at $70.” Craig attached a
    table to a December 2005 email, listing “Estimates for
    Speculative Oil and Gas Reserves,” specifying a range
    between 1.0 and 6.1 billion barrels for the “Chukchi Shelf.”
    Finally, in a May 2006 email Craig wrote, “The ‘1-billion
    barrel, first field’ assumption is subjective (‘for purposes of
    analysis’) and represents only a fraction of the full economic
    resource potential in the Chukchi (which was recently
    published).”
    The mean estimate of economical oil production, at the
    center of the distribution curve, is by definition a more likely
    occurrence than is the lowest estimate of viable oil
    production. Previous EISes in the Chukchi Sea had used the
    mean estimate of oil production as the basis for their
    analyses, and those EISes had also included low and high
    28      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    estimates. For example, BOEM previously leased portions of
    the Chukchi Sea in now-expired Lease Sale 109. The parcels
    leased in Lease Sale 109 overlap substantially with the
    parcels leased in Lease Sale 193. Documents prepared in
    advance of Lease Sale 109 stated that “[t]he mean resource
    estimate . . . is 2.68 billion barrels of oil with a 20 percent
    chance of a discovery of commercially recoverable oil.” In
    estimating the effects of oil spills from Lease Sale 109,
    BOEM “assume[d] the full development of the resource
    estimate of 2.68 billion barrels.” In contrast, while estimates
    in the record about the economically recoverable amount of
    oil from Lease Sale 193 vary, nowhere is the mean amount of
    economical production calculated to be less than 2.37 billion
    barrels. But the FEIS for Lease Sale 193 uses one billion
    rather than 2.37 billion barrels as the basis for its analysis of
    environmental consequences.
    BOEM’s primary explanation for using its low-end
    estimate for oil production is that this scenario overestimates
    the likely amount of production. BOEM emphasizes that
    because of the remoteness of the area and the risk of
    economic failure, any oil production activity is an unlikely
    result of the lease sale. More specifically, BOEM estimates
    that there is a less than 10 percent likelihood that oil
    development in the region will occur. Defendants argue that
    since the most likely foreseeable outcome is no oil
    development at all, one billion barrels of oil production is
    actually a generous estimate.
    This analysis is flawed. The assumption that there is a 10
    percent chance of commercial oil development is itself
    without a rational basis in the record. Jim Craig first
    developed the estimate “off the top of [his] head” in an email
    exchange. That calculation contradicts estimates used earlier
    NATIVE VILLAGE OF POINT HOPE V. JEWELL                 29
    in the EIS, as well as estimates used in past EISes for the
    Chukchi Sea. Further, BOEM conflates the likelihood of oil
    and gas production with the likelihood of environmental
    effects if such production occurs. Based on its responsibility
    to “‘consider[] all foreseeable direct and indirect impacts’” of
    the proposed action, N. Alaska Envtl. Ctr., 457 F.3d at 975
    (citation omitted), BOEM concluded that oil production was
    “reasonably foreseeable.” There is a substantial basis for this
    in the record because, as noted by BOEM, “the area has high
    oil resource potential and there is existing transportation
    infrastructure to move oil from northern Alaska to distant
    markets.” Once BOEM made the determination that
    production is reasonably foreseeable, it was required to
    consider the full cumulative impact of that production. See
    
    40 C.F.R. § 1508.7
    . Put differently, BOEM might well be
    right that the most likely outcome is that there will be no oil
    development in the Chukchi Sea. But that fact should have
    made no difference to BOEM’s analysis of the reasonably
    foreseeable environmental effects of oil development, if such
    development does occur.
    Second, the FEIS did not take into account variation in oil
    prices in arriving at the estimate that one billion barrels of oil
    are economically recoverable. An assumption of stable prices
    ignores the fact that the amount of economically recoverable
    oil varies substantially depending on oil prices. This may be
    seen, for example, in a 2006 report of the Minerals
    Management Service (a prior incarnation of BOEM), which
    estimated economically recoverable oil from the Chukchi
    Shelf at different prices. At $30 per barrel, the mean estimate
    was 0 barrels; at $46 per barrel, the mean estimate was 2.37
    billion barrels; at $60 per barrel, the mean estimate was 8.38
    billion barrels; at $80 dollars per barrel, the mean estimate
    was 12 billion barrels.
    30      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    Third, BOEM has not provided an adequate explanation
    for its decision to base its EIS only on the amount of oil
    expected to be produced from the first field in the leased area
    of the Chukchi Sea. It is unclear from the record how BOEM
    initially estimated that the first field would produce one
    billion barrels of oil. Jim Craig himself suggested that his
    calculations regarding that first development were “entirely
    speculative.” But even assuming that one billion barrels is an
    accurate estimate of the amount of oil to be produced from
    the first field, it is unclear why BOEM assumed that only one
    oil field would be developed in the lease area. The FEIS
    itself acknowledges that “[w]hen the first project overcomes
    the cost, logistical, and regulatory hurdles, more projects are
    . . . likely to follow.”
    The FEIS explains that it is unlikely that “all
    economically viable resources will be developed” in the Sea
    due to the difficulties in operating in a frontier area of oil
    production. But the FEIS does not explain why production
    would be expected to stop if the first oil field is developed.
    The primary explanation for that assumption suggested by the
    record is that data to analyze “the full economic potential” of
    the lease sale would not be available until about two months
    after Jim Craig initially proposed an estimate based on the
    first field. Previous evaluations of Chukchi Sea oil
    development had assumed that multiple oil fields would
    develop once commercial development was viable. In a
    technology assessment of Chukchi Sea petroleum
    development performed in 1983 for BOEM, the Bureau of
    Land Management had used a 1.5 billion barrel estimate to
    measure prospects in “the central Chukchi shelf.” That
    assessment assumed that two oil fields would be developed:
    one of one billion barrels and one of 0.5 billion barrels. On
    the record before us, it remains unclear why BOEM chose to
    NATIVE VILLAGE OF POINT HOPE V. JEWELL                31
    analyze the lowest amount of oil that could be produced in
    the Chukchi Sea from the smallest number of oil fields that
    could be developed.
    Defendants contend that any error resulting from using
    the one billion barrel estimate can be corrected through site-
    specific EISes later in the development process. We disagree.
    An agency is required to analyze the environmental effects in
    an EIS as soon as it is “reasonably possible” to do so. Kern,
    
    284 F.3d at 1072
    . An appropriate time to estimate the total
    oil production from the lease sale is the time of the lease sale
    itself. Under NEPA, BOEM is required to take into account
    the full environmental effects of its actions when deciding
    whether and in what manner to pursue the lease sale.
    
    42 U.S.C. § 4332
    (2)(C). A later project or site-specific
    environmental analysis is an inadequate substitute for an
    estimate of total production from the lease sale as a whole.
    It is only at the lease sale stage that the agency can adequately
    consider cumulative effects of the lease sale on the
    environment, including the overall risk of oil spills and the
    effects of the sale on climate change. It is also only at the
    lease sale stage that the agency can take into account the
    effects of oil production in deciding which parcels to offer for
    lease.
    We also disagree with defendants that our decisions in
    Akutan, 869 F.2d at 1191–92, False Pass, 
    733 F.2d at 617
    ,
    and Watt, 
    683 F.2d at
    1267–68, compel a contrary result. In
    False Pass, plaintiffs challenged the agency for failing to
    consider the worst case scenario for oil development.
    773 F.2d at 614. In the circumstances presented there, we
    held that there was a rational explanation for not considering
    the worst case at the lease sale stage. Here, in contrast, the
    BOEM considered only the best case scenario for
    32      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    environmental harm, assuming oil development. A best case
    scenario “skew[s]” the data toward fewer environmental
    impacts, and thus impedes a “full and fair discussion of the
    potential effects of the project.” Native Ecosystems Council

    Unlike in Akutan, BOEM’s estimate did not merely
    inform an assessment of the likelihood of an oil spill.
    869 F.2d at 1192. Among other things, its estimate informed
    an assessment of seismic effects, habitat effects, oil
    production, and the cumulative effects of the sale on global
    warming.      BOEM’s estimate also informed FWS’s
    determination that Lease Sale 193 would not jeopardize listed
    species. The record suggests that FWS was close to finding,
    even under the one billion barrel assumption, that the lease
    sale would jeopardize the spectacled and Steller’s eiders.
    Had BOEM not selected the least amount of oil necessary for
    production, FWS may well have concluded that the listed
    species were in jeopardy. See 
    16 U.S.C. § 1536
    (a)(2).
    Finally, the degree of error in the estimation of total oil
    production is greater here than in our earlier cases. In Watt,
    the agency was ready to publish its EIS when newly available
    figures suggested that oil reserves were “roughly twice those
    originally estimated.” 
    683 F.2d at 1267
    . We held in Watt
    that the agency had acted reasonably when it decided not to
    supplement its EIS with last-minute analysis of the risk of an
    oil spill based on the new figures. 
    Id.
     at 1267–68. In the case
    before us, BOEM was fully aware from the very beginning
    that if one billion barrels could be economically produced,
    many more barrels could also be economically produced.
    Indeed, at current oil prices, it would be economical to
    NATIVE VILLAGE OF POINT HOPE V. JEWELL             33
    recover twelve times the one billion barrel estimate used by
    BOEM. This is a far more dramatic difference than in Watt.
    We do not criticize BOEM’s decision to estimate the total
    amount of economically recoverable oil from the lease sale.
    Given the uncertainties involved in the Chukchi Sea, BOEM
    had no choice but to make an estimate. But having decided
    that oil production was reasonably foreseeable, NEPA
    required BOEM to base its analysis on the full range of likely
    production if oil production were to occur. It did not do so
    here.
    Conclusion
    We conclude that the FEIS and SEIS properly took
    account of incomplete or unavailable information. However,
    we conclude that reliance in the FEIS on a one billion barrel
    estimate of total economically recoverable oil was arbitrary
    and capricious.
    We REVERSE and REMAND to the district court for
    further proceedings consistent with this opinion.
    RAWLINSON, Circuit Judge, concurring in part and
    dissenting in part:
    I agree with most of the majority opinion, including that
    the missing information from the final environmental impact
    statement (FEIS) and the Supplemental Environmental
    Impact Statement (SEIS) is not essential to informed
    decisionmaking at the lease sale stage, and that further
    environmental analysis will be more appropriate at a later
    34      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    stage. However, I do not agree that the Bureau of Ocean
    Energy Management, Regulation and Enforcement (BOEM)
    acted arbitrarily in selecting one billion barrels of oil as the
    benchmark for analyzing the environmental effects of the
    proposed leases.
    I begin with a reminder that our review of the agency’s
    analysis of technical data is extremely limited. See Lands
    Council v. McNair,

    the National Environmental Policy Act (NEPA) “does not
    mandate particular results.” Dep’t of Transp. v. Pub. Citizen,

    The majority opinion takes issue with the agency’s
    selection of one billion barrels of oil as the benchmark
    amount for assessing potential environmental effects of the
    oil leases. However, our review is at its most deferential
    when we consider a predictive estimate such as BOEM’s
    estimate of the amount of oil recovery that should be included
    in the environmental effects analysis. See Lands Council,
    
    537 F.3d at 993
     (“[W]e are to conduct a particularly
    NATIVE VILLAGE OF POINT HOPE V. JEWELL               35

    areas that are within the agency’s field of discretion and
    expertise . . .) (citations and internal quotation marks
    omitted). Our task is only to ensure that the agency has not:
    relied on factors which Congress has not
    intended it to consider, entirely failed to
    consider an aspect of the problem, offered an
    explanation for its decision that runs counter
    to the evidence before the agency, or an
    explanation that is so implausible that it could
    not be ascribed to a difference in view or the
    product of agency expertise.
    
    Id.
     (citations, alteration, and internal quotation marks
    omitted).
    The majority does not intimate that BOEM relied on
    factors Congress did not intend it to consider, or that BOEM
    entirely failed to consider an aspect of the problem. The
    majority opinion also cannot be fairly read to describe
    BOEM’s benchmark choice as so implausible that it could not
    be ascribed to a difference in view or the product of agency
    expertise. In fact, the majority opinion discusses the different
    views and agency expertise brought to bear on this issue. See
    Majority Opinion, pp. 21–26 (discussing the differing views
    from within and without the agency). So it appears that the
    basis for the majority’s ruling is that BOEM’s benchmark
    estimate runs counter to the evidence before the agency. But
    it doesn’t.
    The potential size of commercially extractable oil
    deposits in the Chukchi Sea is a quintessential example of a
    predictive judgment uniquely within BOEM’s area of
    36      NATIVE VILLAGE OF POINT HOPE V. JEWELL
    expertise. Indeed, we have previously recognized that
    “[p]rior to exploration, it is difficult to make so much as an
    educated guess as to the volume of oil likely to be produced
    . . . Without this information, an oil spill risk analysis can
    never be more than speculative, regardless of what
    methodology is used. . . .” Tribal Village of Akutan v. Hodel,
    
    869 F.2d 1185
    , 1192 (9th Cir. 1989), as amended.
    It is beyond dispute that the Chukchi Sea contains oil
    deposits well in excess of one billion barrels. But that is not
    the point. The point is whether the selection of one billion
    barrels as the benchmark was the product of agency expertise.
    See Lands Council, 
    537 F.3d at 993
    . After considering the
    available evidence, BOEM concluded that substantial
    obstacles to oil development in the region made it unlikely
    that future production would “ever reach the full economic
    potential” in the Chukchi Sea. Five explorations had already
    tested some of the largest prospective sites without
    discovering a “commercial-size” oil source. With these
    circumstances in mind, BOEM ultimately selected one billion
    barrels as the benchmark estimate because lower oil volumes
    were not likely to be economically feasible. Rather than
    relying on general resource assessments as was done
    previously, BOEM opted for the more “realistic” benchmark
    tied to the discovery/development of the initial commercially
    viable offshore oil field. BOEM explained that the unique,
    remote, and previously unexplored nature of the Chukchi
    region required analysis of the “statistically most-likely
    development activity associated with a reasonable range of
    resources . . . given the uncertainties of geology, engineering,
    and economics that exist now” and the “streamlined”
    environmental impact statement (EIS) undertaken at the
    leasing stage of the process. See Akutan, 
    869 F.2d at
    1192
    NATIVE VILLAGE OF POINT HOPE V. JEWELL               37
    (“We are the least troubled by what may seem to be
    incomplete or speculative data at the lease sale stage. . . .”).
    The majority is of the view that BOEM’s “analysis is
    flawed.” Majority Opinion, p. 28. But we do not sit as a
    panel of super scientists to dissect the agency’s analysis.
    Rather, we only review the process for reasonable
    thoroughness. See Edwardsen, 
    268 F.3d at 784
     (establishing
    the role of the reviewing court to determine whether the
    agency’s environmental impact statement “contains a
    reasonably thorough discussion”). Not only was BOEM’s
    discussion of the selected benchmark “reasonably thorough,”
    
    id.,
     its selection of the benchmark was within the range of
    alternatives contained in the record. As the majority opinion
    acknowledges, a previous EIS had estimated a range of
    economical oil production from 0.96 billion barrels to 2.42
    billion barrels. See Majority Opinion, p. 24. One billion
    barrels is certainly within that range. The same is true for the
    “range between 1.0 and 6.1 billion barrels” referenced at page
    27 of the Majority Opinion.
    I readily acknowledge that there was disagreement in the
    scientific community concerning the selected benchmark.
    But disagreement does not render the chosen estimate
    irrational. Rather, it typifies the “difference in view” that we
    have established as a safe harbor against successful attack
    under NEPA. See Lands Council, 
    537 F.3d at 993
    . There is
    no such thing as a perfect estimate and BOEM was not
    required to adopt a different benchmark in the face of its
    critics. See Environmental Defense Center, Inc. v. EPA,
    
    344 F.3d 832
    , 872 (9th Cir. 2003) (“We defer to an agency
    decision not to invest the resources necessary to conduct the
    perfect study . . .”). BOEM explained its reasons for
    selecting its benchmark estimate, and we are uniquely
    38       NATIVE VILLAGE OF POINT HOPE V. JEWELL
    unqualified to second-guess that selection. As the D.C.
    Circuit recognized in City of L.A. v. Dep’t of Transp.,
    
    165 F.3d 972
    , 977 (D.C. Cir. 1999): “[That some or many
    [experts] would disapprove of [BOEM’s] approach does not
    answer the question presented to us. In reviewing [BOEM’s
    EIS], we do not sit as a panel of referees on a professional
    [scientific] journal, but as a panel of generalist judges obliged
    to defer to a reasonable judgment by an agency acting
    pursuant to congressionally delegated authority. . . .”)
    (citations omitted).
    Because of the deference due the agency, and because
    BOEM’s chosen benchmark was reasonably selected and
    adequately explained, our work here is done. We should
    afford BOEM’s EIS the deference due and affirm the district
    court’s order of dismissal.
    I respectfully dissent.
