    Appeal from the United States District Court
    for the Western District of Texas
    _________________________________________________________________
    Before JOLLY, SMITH, and EMILIO M. GARZA, Circuit Judges.
    E. GRADY JOLLY, Circuit Judge:
    Before this court is the joint decision of two government
    agencies not to conduct a full-scale environmental impact study of
    the environmental effects of a proposal to use a pre-existing
    pipeline to transport gasoline and other petroleum products across
    the state of Texas. The government agencies did perform an initial
    environmental assessment but declined to engage in any further
    studies after concluding that the environmental impact of the
    proposed use of the pipeline would not be significant.                        The
    petitioners consist of a variety of Texas cities and governmental
    entities strongly opposed to the proposed use of this particular
    pipeline.   They urged the district court -- and they now urge this
    court -- to order the government agencies to proceed with a full-
    fledged environmental impact study, contending that the agencies’
    finding of no significant environmental impact was arbitrary and
    capricious and contrary to law.                The district court upheld the
    conclusion of the government agencies.             We affirm.
    I.    Background
    A.   Statutory Background
    This   case        arises     under   the    network   of     the   National
    Environmental Policy Act of 1969 (“NEPA”), 
    42 U.S.C. §§ 4321
    -4370d,
    “a statute drafted to ensure that federal agencies ‘carefully
    consider detailed information concerning significant environmental
    impacts,’   and    at    the     same   time   ‘guarantee   that   the   relevant
    2
    information will be made available to the larger audience that may
    also play a role in both the decisionmaking process and the
    implementation of that decision.’”         Sabine River Authority v. U.S.
    Dept. of Interior, 
    951 F.2d 669
    , 676 (5th Cir. 1993) (quoting
    Robertson v. Methow Valley Citizens Council, 
    490 U.S. 332
     (1989)).
    In essence, the NEPA framework requires federal agencies to prepare
    a detailed Environmental Impact Statement (“EIS”) for all “major
    federal actions significantly [affecting] the quality of the human
    environment.”    
    42 U.S.C. § 4332
    (C).
    The threshold determination of whether the effect of the
    proposed action is sufficiently "significant" to necessitate the
    production of an EIS is made by the preparation of an Environmental
    Assessment (“EA”).    Sabine River, 951 F.2d at 677.           The EA is a
    "concise" document that "briefly" discusses the relevant issues and
    either reaches a conclusion that preparation of an EIS is necessary
    or concludes with a "Finding of No Significant Impact" ("FONSI").
    Id.      An EA is conducted to “provide sufficient evidence and
    analysis for determining whether to prepare an [EIS].” 
    40 C.F.R. § 1508.9
    (a)(1).    “The EA is a rough-cut, low-budget environmental
    impact    statement   designed   to       show   whether   a   full-fledged
    environmental impact statement -- which is very costly and time-
    consuming to prepare and has been the kiss of death to many a
    federal project -- is necessary.”          Sabine River, 951 F.2d at 677
    (internal quotations and citations removed).           Thus, the ultimate
    purpose of the EA is to lead to one of two findings:           “either that
    3
    the project requires the preparation of an EIS to detail its
    environmental impact, or that the project will have no significant
    impact . . . necessitating no further study of the environmental
    consequences which would ordinarily be explored through an EIS.”
    Id.     If the former is found, then the agency must proceed with a
    full blown EIS; if the latter is found, the agency issues a FONSI
    and has no further obligations under NEPA.         Id.
    Notably, the NEPA statutory framework provides no substantive
    guarantees; it prescribes adherence to a particular process, not
    the production of a particular result.        Robertson, 
    490 U.S. at 350
    .
    NEPA “is a procedural statute that demands that the decision to go
    forward with a federal project which significantly affects the
    environment be an environmentally conscious one.”           Sabine River,
    951 F.2d at 676.    The statute “does not command the agency to favor
    an environmentally preferable course of action, only that it make
    its decision to proceed with the action after taking a ‘hard look
    at environmental consequences.’”         Id. (quoting Robertson, 
    490 U.S. at 350
    ).      Indeed, “NEPA does not prohibit the undertaking of
    federal projects patently destructive of the environment; it simply
    mandates that the agency gather, study, and disseminate information
    concerning the projects' environmental consequences.”          
    Id.
       Thus,
    while    “[o]ther   statutes   may   impose   substantive   environmental
    obligations on federal agencies, . . . NEPA merely prohibits
    uninformed -- rather than unwise -- agency action."          
    Id.
    4
    B. Factual and Procedural History
    This case concerns a pipeline that runs across the state of
    Texas between Houston and El Paso.               Along its way, the pipeline
    passes through the City of Austin and across several rivers,
    streams and wetlands.      In addition, it lies atop several aquifers
    and aquifer recharge zones.        Exxon Pipeline Company originally
    constructed the pipeline between 1949 and 1950 and used it to
    transport crude oil until 1995.        In 1997, Exxon sold the pipeline
    to   Longhorn   Partners   Pipeline,       L.P.    (“Longhorn”),   a   Delaware
    limited liability    partnership       headquartered      in   Dallas,   Texas.
    Longhorn purchased the pipeline intending to use it to transport
    gasoline and other petroleum products from Gulf Coast refineries to
    El Paso and then, perhaps, on to other states.             The pipeline will
    eventually move approximately 225,000 barrels of gasoline per day
    across its lines.
    On April 22, 1998, Mariane Collins, the Barton Springs-Edwards
    Aquifer   Conservation     District,       and    David   Robertson    filed   a
    challenge to the proposed pipeline under NEPA.1             In their original
    complaint, the plaintiffs sought injunctive relief, claiming that
    1
    The Collins plaintiffs all claim to be potentially affected
    by the proposed use of the pipeline. Marian Collins is a rancher
    in Kimble County, Texas and claims she is totally dependent on
    water drawn from the Edwards-Trinity Plateau Aquifer which is
    allegedly threatened by this pipeline. David Robertson lives in
    Hayes County and claims to rely on well-water drawn from this same
    aquifer. The Barton Springs-Edwards Aquifer Conservation District
    is a political subdivision charged with the protection of the
    Barton Springs segment of the Edwards Aquifer.
    5
    NEPA obligated the federal government to perform a full-fledged
    review of the environmental impact of the proposed use of the
    Longhorn Pipeline.        The suit was brought against Longhorn, the
    United States, the United States Department of Transportation
    (“DOT”),    the   Department     of    the    Army,   and   the   Environmental
    Protection Agency (“EPA”).       Shortly thereafter, the City of Austin
    was allowed to intervene as the pipeline itself runs through the
    city.
    After some initial negotiations, Longhorn and the government
    defendants entered into a settlement stipulation with the Collins
    plaintiffs   and    the   City   of    Austin    (collectively     referred   to
    hereafter as “the Collins plaintiffs”). Under this settlement, the
    EPA and the DOT (hereafter referred to as the “Lead Agencies”)
    agreed to prepare an EA of the pipeline.              The parties agreed that
    this EA would culminate in a FONSI or a notice of intent to prepare
    an   EIS.    Upon   acceptance    of    the    settlement    stipulation,     the
    district court issued an Agreed Order enjoining Longhorn from
    placing petroleum products in the pipeline until thirty days after
    the EA had been completed.       The Agreed Order also specified that if
    the Lead Agencies issued a FONSI, the Collins plaintiffs could
    apply to the court to extend the injunction on the basis that the
    FONSI was arbitrary and capricious or otherwise in violation of the
    law under the Administrative Procedures Act (“APA”), 
    5 U.S.C. § 706
    .
    6
    In    accordance        with   the   settlement   stipulation,      the    Lead
    Agencies prepared an EA.            On October 28, 1999, the Lead Agencies
    issued the draft EA and a preliminary FONSI for public review and
    comment (in accordance with 
    40 C.F.R. § 1506.6
    ).                   The preliminary
    FOSNI was a so-called “mitigated FONSI” which means that its
    issuance was predicated on Longhorn’s engaging or agreeing to
    engage    in    certain      mitigation    measures.       These    measures    were
    designed to       address     the   potentially     significant      environmental
    impacts of the pipeline and reduce the risks of them occurring to
    a level where they were deemed insignificant by the Lead Agencies.
    The Lead Agencies then held public hearings on the draft EA and the
    preliminary FONSI in Austin, Houston, Fredricksburg, Bastrop and El
    Paso and distributed hundreds of copies of the EA and FONSI in
    counties       along   the    pipeline.        Following   these    hearings,    the
    submission of several thousand written comments on them, and after
    further deliberation, on November 3, 2000, the EPA and DOT issued
    a FONSI along with the final EA.
    On February 5, 2001, the District Court granted the Collins
    plaintiffs leave to amend their initial complaints.                      In their
    amended complaint, the Collins plaintiffs contended that (1) the
    Lead Agencies’ decision to issue a FONSI instead of preparing an
    EIS was contrary to NEPA and was arbitrary and capricious in
    violation of the APA, and (2) the Lead Agencies and Longhorn
    breached the settlement agreement.               In response, Longhorn and the
    7
    Lead Agencies claimed that the decision to issue a FONSI was not
    arbitrary and capricious and that they had complied with the
    settlement agreement.    All parties filed summary judgment motions
    on June 10, 2002.
    On July 19, 2002, the district court granted summary judgment
    in favor of Longhorn and the Lead Agencies.   It found that the Lead
    Agencies’ decision to issue a FONSI and not prepare an EIS was not
    arbitrary and capricious nor was it in any other way unlawful or in
    violation of NEPA.    Specifically, it found that the Lead Agencies
    had taken the requisite “hard look” at the environmental impact of
    the Longhorn Pipeline and had reasonably determined that the impact
    would not be significant.   In addition, it found that Longhorn had
    not breached the settlement agreement.
    On August 20, 2002, the Collins plaintiffs filed a timely
    notice of appeal to this Court.       In this appeal, the Collins
    plaintiffs take issue with the district court’s finding that the
    Lead Agencies’ decision to issue a FONSI and not to prepare an EIS
    was not arbitrary and capricious or otherwise in violation of the
    law.   They urge this Court to reverse this finding, remanding with
    instructions that the district court remand the proceeding to the
    Lead Agencies for preparation of an EIS, or alternatively, for
    8
    reconsideration         of    the     FONSI       in    response       to    a    judicial
    determination that it was issued in violation of NEPA.2
    II.    Standard of Review
    Because NEPA dictates no particular substantive result, an
    agency     decision     not    to    conduct      an    EIS    based    on   a   FONSI    is
    reviewable only on procedural grounds.                      A party objecting to such
    a decision brings such a challenge under the APA, 
    5 U.S.C. § 706
    (2)(A).      Such parties face a high bar to success, however, as
    NEPA-related         decisions      are   accorded      a     considerable       degree   of
    deference.      The Supreme Court has held that in reviewing agency
    decisions involving alleged NEPA violations, courts are to uphold
    the     agency’s      decision       unless       the    decision       is   “arbitrary,
    capricious, an abuse of discretion, or otherwise not in accordance
    with law.”      Marsh v. Oregon National Res. Council, 
    490 U.S. 360
    ,
    375 n.21 (1989)(quoting 
    5 U.S.C. § 706
    (2)(A)).                       Under this “highly
    deferential” standard, a reviewing court has the “least latitude in
    finding grounds for reversal” of an agency decision and “may not
    substitute its judgment for that of the agency.”                       Sabine River, 951
    F.2d at 678 (internal quotations and citations omitted).                             Thus,
    with respect to this case, our deferential role as a reviewing
    court is limited to ensuring that the Lead Agencies took a “hard
    look”     at   the    environmental       consequences;         we     cannot    interject
    2
    The Collins plaintiffs do not appeal the district court’s
    grant of summary judgment on their claim that Longhorn breached its
    settlement agreement. Thus, the sole issue before us on appeal is
    the validity of the Lead Agencies’ decision not to conduct an EIS.
    9
    ourselves within the area of discretion of the agencies as to the
    ultimate choice of the action to be taken.         Kleppe v. Sierra Club,
    
    427 U.S. 390
    , 410 n. 21 (1976).           In doing so, we evaluate the
    record de novo.     We undertake the same task as the district court,
    reviewing the materials submitted there and determining whether the
    agency's conclusions were arbitrary and capricious or contrary to
    law.    Sabine River, 951 F.2d at 679.
    III.   Discussion
    Before examining the Collins plaintiffs’ arguments in detail,
    we should first note how exceedingly thorough and comprehensive the
    instant environmental assessment prepared by the Lead Agencies
    appears to be.     The law only requires that an EA be a “rough-cut,”
    “low-budget,” preliminary look at the environmental impact of a
    proposed project.       Sabine River, 951 F.2d at 677.             This EA,
    however, is anything but rough-cut or low-budget.            One and a half
    years in the making, it consists of four lengthy volumes numbering
    over 2,400 pages.     It incorporates not only the analysis of agency
    personnel but also studies from independent experts in pipeline
    operations and safety, endangered species, hydrology, geology, lake
    and    stream   modeling,   chemistry,    risk   analysis,   and   emergency
    response planning and implementation.            It also incorporates the
    Lead Agencies’ review of over 6,000 written comments and numerous
    oral comments from six separate public meetings held throughout
    potentially affected areas in the state of Texas. Its issuance was
    predicated on Longhorn’s agreeing to employ and maintain a variety
    10
    of mitigation measures designed to lower the degree of identified
    risk of impact to acceptable levels.             Indeed, in many ways, this EA
    is more akin to a full-blown EIS; it is unclear exactly what more
    the Lead Agencies could have done to evaluate the significance of
    this pipeline’s impact.
    We should also note that we find nothing objectionable about
    the fact that the issuance of the FONSI was predicated on Longhorn
    agreeing to certain mitigation measures.                     This Court has never
    explicitly upheld the issuance of a so-called “mitigated FONSI.”
    This situation occurs when an agency or an involved third party
    agrees to employ certain mitigation measures that will lower the
    otherwise significant impacts of an activity on the environment to
    a level of insignificance.            In this way, a FONSI could be issued
    for an activity that otherwise would require the preparation of a
    full-blown EIS. Other circuits have endorsed such a practice. For
    example, in Cabinet Mountains Wilderness v. Peterson, 
    685 F.2d 678
    (D.C. Cir. 1982), the District of Columbia Circuit Court of Appeals
    held    that   “if,     however,      a     proposal    is    modified    prior   to
    implementation     by    adding       specific       mitigation    measures   which
    completely     compensate      for    any    possible     adverse    environmental
    impacts    stemming     from    the       original     proposal,    the   statutory
    threshold of significant environmental effects is not crossed and
    an EIS is not required.”         Other circuits have concurred with this
    result.    See, e.g., C.A.R.E. Now, Inc. v. FAA, 
    844 F.2d 1569
     (11th
    Cir. 1988); Greenpeace Action v. Franklin, 
    14 F.3d 1324
     (9th Cir.
    11
    1992); Roanoke River Basin Ass’n v. Hudson, 
    940 F.2d 58
     (4th Cir.
    1991); Audubon Soc’y of Cent. Arkansas v. Dailey, 
    977 F.2d 428
     (8th
    Cir. 1992).      While we have never explicitly upheld the use of a
    mitigated FONSI, we have implicitly endorsed their use in Sierra
    Club v. Espy, 
    38 F.3d 792
    , 803 (5th Cir. 1994) (holding that EAs
    satisfied NEPA where they considered appropriate alternatives,
    including mitigation measures), and Louisiana v. Lee, 
    758 F.2d 1081
    , 1083 (5th Cir. 1985) (holding that it was proper to consider
    restrictions placed on dredging permits in reviewing the agency’s
    decision not to file an EIS and citing Cabinet Mountains, 
    685 F.2d at 682
    ).      Accordingly, we find no basis for objecting to the
    mitigated nature of FONSI issued here.        This is particularly true
    given the fact that the original settlement agreement between the
    parties specifically endorsed the use of a mitigated FONSI.
    Despite its comprehensive nature, the Collins plaintiffs take
    issue with the conducted EA and issued FONSI on three basic
    grounds. First, they contend that the Lead Agencies’ assessment of
    the environmental impact of the pipeline was conducted in bad faith
    – that a political decision to issue a FONSI had been                  made
    beforehand and the entire process was specifically tailored to
    produce this result.      Second, they assert that the Lead Agencies
    did not follow the guidelines set out by relevant NEPA regulations;
    specifically, they argue that the Lead Agencies failed to consider
    and   evaluate    all   the   requisite   factors   stipulated   by   these
    regulations.      Finally, the Collins plaintiffs assert that even
    12
    assuming a sufficiently comprehensive “hard look” was taken, the
    Lead Agencies’ findings were arbitrary and capricious since a clear
    and rational examination of the record indicates that the Longhorn
    Pipeline would have a significant effect on the environment.                              The
    Collins plaintiffs        made    all    three       of   these    arguments        to    the
    district court, which rejected them.                 We do so as well.
    As     to   their    first       contention,         the    Collins      plaintiffs
    essentially      assert   that    the    EA    prepared         here   was    a    sham    --
    contrived reports specifically tailored to rationalize a result
    that had already been predetermined. They assert that the decision
    to not prepare an EIS was a political decision made in advance by
    the Council on Environmental Quality (“CEQ”) -- an executive branch
    political    organization        --    and    forced      on     the   Lead       Agencies.
    Consequently, they argue that there was never any good faith
    attempt to       take   the   required       “hard    look”      at    any   potentially
    significant environmental effects the proposed action would have.
    Instead, the EA that ultimately issued was a foregone conclusion,
    whatever may have been the actual level of the significance of the
    pipeline’s impacts.
    We find no merit to this argument.                   Although it is true that
    agencies are expected to engage in good faith fact-finding, when
    their findings are challenged as arbitrary and capricious, the
    agencies’ actions are judged in accordance with their stated
    reasons.    See, e.g., In re: Comptroller of the Currency, 
    156 F.3d 1279
     (D.C. Cir. 1998).        Thus, the “actual subjective motivation of
    13
    agency decisionmakers is immaterial as a matter of law -- unless
    there is a showing of bad faith or improper behavior.” 
    Id.
     at 1279-
    80.    There is no evidence here that the Lead Agencies acted
    improperly or in bad faith.      The assessment they prepared was
    noteworthy for its exhaustive and extensive nature.       Even more
    detrimental to the Collins plaintiffs’ argument is that there is no
    evidence of a causal link between the Lead Agencies’ decision to
    issue a FONSI and the alleged political machinations; the record
    suggests that the CEQ’s involvement did not come until after the
    Lead Agencies had made the initial decision not to prepare an EIS.
    Accordingly, there is no reason to overturn the Lead Agencies’
    decision on these grounds.
    As to the second contention, the Collins plaintiffs accurately
    note that in taking a “hard look” at whether a proposed activity’s
    impact will be significant, the relevant regulations instruct the
    Lead Agencies to consider both the “context” and the “intensity” of
    the impacts. 
    40 C.F.R. § 1508.27
    . According to these regulations,
    consideration of context means that “the significance of an action
    must be analyzed in several contexts such as society as a whole
    (human, national), the affected region, the affected interests, and
    the locality.” 
    40 C.F.R. § 1508.27
    (a).     Intensity is defined as
    “the severity of impact.” 
    40 C.F.R. § 1508
    (b). The regulation then
    goes on to provide ten areas agencies should consider in evaluating
    14
    “intensity.”   See id.3    The Collins plaintiffs contend that while
    the Lead Agencies’ EA report accurately lists all ten factors as
    being components of their assessment, their failure to specifically
    address each   of   them   separately     and   directly    in    this   report
    requires reversal.        We do not think, however, that the Lead
    Agencies’   decision   should   be   overturned     on     such   formalistic
    grounds.    Notably, the factors listed in the regulation do not
    3
    The ten listed factors are:
    (1) Impacts that may be both beneficial and adverse. A significant
    effect may exist even if the Federal agency believes that on
    balance the effect will be beneficial.
    (2) The degree to which the proposed action affects public health
    or safety.
    (3) Unique characteristics of the geographic area such as proximity
    to historic or cultural resources, park lands, prime farmlands,
    wetlands, wild and scenic rivers, or ecologically critical areas.
    (4) The degree to which the effects on the quality of the human
    environment are likely to be highly controversial.
    (5) The degree to which the possible effects on the human
    environment are highly uncertain or involve unique or unknown risks.
    (6) The degree to which the action may establish a precedent for
    future actions with significant effects or represents a decision in
    principle about a future consideration.
    (7) Whether the action is related to other actions with
    individually insignificant but cumulatively significant impacts.
    Significance exists if it is reasonable to anticipate a
    cumulatively significant impact on the environment. Significance
    cannot be avoided by terming an action temporary or by breaking it
    down into small component parts.
    (8) The degree to which the action may adversely affect districts,
    sites, highways, structures, or objects listed in or eligible for
    listing in the National Register of Historic Places or may cause
    loss or destruction of significant scientific, cultural, or
    historical resources.
    (9) The degree to which the action may adversely affect an
    endangered or threatened species or its habitat that has been
    determined to be critical under the Endangered Species Act of 1973.
    (10) Whether the action threatens a violation of Federal, State, or
    local law or requirements imposed for the protection of the
    environment.
    15
    appear to be categorical rules that determine by themselves whether
    an impact is significant.              Instead, they are simply a list of
    relevant factors that should be considered in gauging whether an
    impact is “intense” and, therefore, significant. As such, all that
    would have to be shown is that all the factors were in some way
    addressed and evaluated; whether this was done in factor-by-factor
    fashion is irrelevant.          We think that the record clearly indicates
    that   each   of   these       factors   received     adequate    attention     and
    evaluation    in        the    Lead   Agencies’     decision-making       process.
    Accordingly, we find no merit to this argument.
    The Collins plaintiffs finally assert that, even assuming a
    comprehensive “hard look” was taken, the conclusion that the impact
    of the Longhorn Pipeline was not significant was still arbitrary
    and capricious since the Lead Agencies’ conclusion was both grossly
    unsupported by the facts found and premised on bad science and/or
    inaccurate    information.             They   argue    that      any    reasonable
    consideration      of    the   ten    requisite   factors   would      have   led a
    rational decision-maker to conclude that the environmental impact
    of the Longhorn Pipeline would be significant.                According to them,
    the EA report, the FONSI, and its underlying studies and findings
    are “unduly optimistic,” “confusing,” “unreasonable” and “defy
    common sense.”      To substantiate these allegations, they offer the
    detailed testimony of five expert witnesses retained by them.
    We find no merit to this contention.                 The fact that the
    Collins plaintiffs or their experts take great issue with the
    16
    factual findings and ultimate conclusions of the Lead Agencies does
    not   render   those   findings   and   conclusions   “arbitrary   and
    capricious.”   As we noted earlier, government agencies -- and not
    the federal courts -- are the entities NEPA entrusts with weighing
    evidence and reaching factual conclusions:
    Where conflicting evidence is before the
    agency, the agency and not the reviewing court
    has the discretion to accept or reject from
    the several sources of evidence. The agency
    may even rely on the opinions of its own
    experts, so long as the experts are qualified
    and express a reasonable opinion.
    Sabine River, 951 F.2d at 678.
    Indeed, even if we were convinced that the Collins plaintiffs’
    experts were more persuasive than those relied upon by the Lead
    Agencies, we would still be compelled to uphold the Lead Agencies’
    finding so long as their experts were qualified and their opinions
    reasonable.    Id.; Marsh, 
    490 U.S. at 378
     (“[w]hen specialists
    express conflicting views, an agency must have the discretion to
    rely on the reasonable opinions of its own qualified experts, even
    if, as an original matter, a court might find contrary views more
    persuasive.”).
    There is no evidence here that the Lead Agencies’ experts are
    unqualified, nor do their opinions seem unreasonable to us.        The
    Collins plaintiffs’ experts point to a number of specific flaws
    they claim exist in the Lead Agencies’ fact-finding or conclusions.
    These include allegations that the Lead Agencies should have
    conducted more comprehensive studies than they chose to do, that
    17
    they utilized inaccurate and misleading statistical methodology in
    analyzing the risks of pipeline leakage, that they ignored or
    finessed the implications of key findings by the Lead Agencies’ own
    experts in many instances, and that they inappropriately deferred
    to   Longhorn   for   data    and   then      relied   uncritically    upon   it.
    Unsurprisingly, the Lead Agencies and Longhorn take issue with each
    of these assertions, answering each point-by-point in their briefs.
    After analyzing this back-and-forth between the parties, it seems
    clear that whatever the merits of the Collins plaintiffs’ arguments
    that the Lead Agencies’ decision-making process was less than
    perfect, it was not unreasonable. Instead, the dispute between the
    Collins plaintiffs and the defendants here is best classified as a
    classic battle of the experts, with each party asserting that their
    analysis is more reasonable than the other’s.                Under the highly
    deferential     standard     afforded    to    agencies   pursuant     to   NEPA,
    however, it is not the job of the federal courts to intervene in
    this fight.4     The agencies have made their decision.               It was not
    4
    The Collins plaintiffs advance the argument that even if the
    environmental impact of the Longhorn Pipeline is not clearly
    significant, it is at least a close call and, as they claim, close
    calls are supposed to lead to an EIS. For this proposition of law,
    they rely on National Audubon Soc’y v. Hoffman, 
    132 F.3d 7
    , 13 (2d
    Cir. 1997)(“[w]hen the determination that a significant impact will
    or will not result from the proposed action is a close call, an EIS
    should be prepared.”). This Court, however, has never announced
    such a rule. Indeed, it would be difficult to do so, given the
    seeming conflict between such a rule and the highly deferential
    “arbitrary and capricious” standard set out in Sabine River.

    arbitrary and capricious.   We are thus obliged to defer to their
    expert judgment.5
    IV.   Conclusion
    As we noted earlier, NEPA does not guarantee any substantive
    results; all it ensures is that a particular process will be
    5
    We should note that our deference to the Lead Agencies fact-
    finding and conclusions includes deference to their judgment as to
    whether any particular environmental impact of the proposed
    pipeline rises to the level of significance.           The Collins
    plaintiffs argue that under the NEPA framework, the determination
    of whether an impact is significant must be objective, factual and
    quantitative in nature and should not involve any subjective,
    qualitative “judgment calls.” They argue that the final EA issued
    here is inappropriately “larded” with such judgement calls,
    particularly on the subject of how much risk constitutes
    significant risk; it should therefore be overturned. The problem
    with this contention is that, as a practical matter, a
    determination of significance cannot be a completely objective
    inquiry because the meaning of the term “significance” for purposes
    of the NEPA statute is not clear on its face. Vieux Carre Property
    Owners, Residents and Assoc’s., Inc. v. Pierce, 
    719 F.2d 1272
    , 1279
    (5th Cir. 1983)(“There is no hard and fast definition of
    ‘significant’ effect.”). As such, determining whether significance
    exists inherently involves some sort of a subjective judgment call.
    Save Our Ten Acres v. Kreger, 
    472 F.2d 463
    , 467 n.7 (5th Cir. 1973)
    (significance is “in large part a judgment based on the
    circumstances of the proposed action.”).        This must include
    judgment calls about how much risk equals significant risk, i.e.,
    judgment calls about “acceptable risk.” This observation has been
    made by the Second Circuit in City of New York v. U.S. Dep’t of
    Transp., 
    715 F.2d 732
     (2d Cir. 1983). There, the court explicitly
    held that agencies have “latitude in determining whether the risk
    is sufficient to require the preparation of an EIS.” 
    Id.
     at 746
    n.14. This holding is sound because the “concept of overall risk
    incorporates the significance of possible adverse consequences
    discounted by the improbability of their occurrence.” 
    Id. at 738
    .
    That is not to say that any such judgment calls must be rubber-
    stamped by a reviewing court; they are still subject to the
    arbitrary and capricious standard of review. However, we do say
    that the simple fact that a judgment call was made is not enough to
    render the determination of significance (or non-significance)
    invalid under NEPA.
    19
    followed.        Herein lies the problem for the Collins plaintiffs.
    They really don’t want more process.            Indeed, considering the
    extensive and comprehensive nature of the EA conducted here, it is
    unclear exactly what more process would involve.6 What they really
    desire is a substantive result:         convinced that it poses a great
    threat to the health and safety of its citizens and the environment
    in general, the Collins plaintiffs want this pipeline project
    killed.     Unfortunately for their case, and whatever of the merits
    of that position, this outcome cannot be secured in this federal
    court proceeding.       The Lead Agencies here have complied with the
    NEPA statute and its accompanying regulations in every way.            They
    have       conducted an exhaustive assessment of the environmental
    effects     of   this   proposed   pipeline   and,   after   consideration,
    6
    The Lead Agencies and Longhorn have argued that requiring the
    preparation of an EIS here would be a waste of time and resources,
    given the fact that the EA prepared here contains all the
    functional elements of an EIS. We find this argument persuasive.
    In Vieux Carre Property Owners, Residents and Assoc’s., Inc. v.
    Pierce, 
    719 F.2d 1272
    , 1282 (5th Cir. 1983), this court upheld the
    decision of an agency not to conduct an EIS where the “objectives
    reflected in the [f]inal [EA] and the procedures followed in its
    preparation were extremely thorough and resulted in a document much
    akin to a detailed environmental impact statement.” But see State
    of Louisiana v. Lee, 
    758 F.2d 1081
     (5th Cir. 1985) (holding that an
    EA prepared by an agency in that case was not the functional
    equivalent of an EIS). Like the EA in Vieux Carre, the EA here has
    all the hallmarks of an EIS:      there were public hearings and
    costly, extensive, and comprehensive environmental studies which
    produced reams of material data and resulted in 2,400 pages of
    analysis. Accordingly, it is unclear whether the time and expense
    required to prepare an EIS after an EA will result in any
    incremental benefits. Forcing the Lead Agencies to prepare an EIS
    would likely be unnecessarily duplicative and a waste of resources.
    20
    concluded that those effects were not significant.      Whether we
    agree or disagree with that conclusion, we cannot call it arbitrary
    and capricious.   Accordingly, we have no ability to disturb it.
    Therefore, the district court’s grant of summary judgment in favor
    of the defendants is AFFIRMED in all respects.
    AFFIRMED
