    SUMMARY **
    Federal Aviation Administration / Environmental Law
    The panel filed (1) an order amending the opinion
    initially filed on November 18, 2021, and amended on
    October 11, 2022; and (2) an amended opinion denying a
    petition for review challenging the Federal Aviation
    Administration (“FAA”)’s Record of Decision, which found
    no significant environmental impact stemming from the
    construction and operation of an Amazon air cargo facility
    at the San Bernardino International Airport (the “Project”).
    To comply with their duties under the National
    Environmental Policy Act (NEPA), the FAA issued an
    Environmental Assessment (EA) that evaluated the
    environmental effects of the Project. In evaluating the
    environmental consequences of the Project, the FAA
    generally utilized two “study areas” – the General Study

    4           CENTER FOR COMMUNITY ACTION V. FAA
    Area and the Detailed Study Area. Petitioners are the Center
    for Community Action and Environmental Justice and others
    (collectively “CCA”), and the State of California.
    In attacking the parameters of the study areas, the CCA
    asserted that the FAA did not conform its study areas to the
    FAA’s Order 1050.1F Desk Reference. The panel held that
    the FAA’s nonadherence to the Desk Reference could not
    alone serve as the basis for holding that the FAA did not take
    a “hard look” at the environmental consequences of the
    Project. Instead, the CCA must show that the FAA’s
    nonadherence to the Desk Reference had some sort of EA
    significance aside from simply failing to follow certain Desk
    Reference instructions. The panel held that the CCA had not
    done so here.
    CCA next asserted that the FAA failed in its obligation
    to sufficiently consider the cumulative impacts of the
    Project. CCA first argued that the FAA only considered
    past, present, and reasonably foreseeable projects within the
    General Study Area and should have expanded its
    assessment to include an additional 80-plus projects. The
    panel held that the record showed that the FAA specifically
    accounted for the traffic generated by these 80-plus projects
    for purposes identifying cumulative traffic volumes. The
    fact that CCA could not identify any potential cumulative
    impacts that the FAA failed to consider suggested that there
    were none. The CCA did not show that the FAA’s
    cumulative impact analysis on air quality would have been
    potentially different if it considered the 80-plus
    projects. Thus, the CCA did not carry its burden to show
    why the FAA was required to consider the 80-plus projects
    in conducting the cumulative impacts analysis on air
    pollution. CCA additionally argued that the EA did not
    disclose specific, quantifiable data about the cumulative
    CENTER FOR COMMUNITY ACTION V. FAA               5
    effects of related projects, and it did not explain why
    objective data about the projects could not be provided. The
    panel held that CCA’s belief that the FAA must provide
    quantifiable data was based on a misreading of this court’s
    precedent. The panel concluded that the CCA and the state’s
    conclusory criticisms of the EA’s failure to conduct a more
    robust cumulative air impact analysis amounted to
    disagreements with the results, not procedures. The panel
    found no reason to conclude that the FAA conducted a
    deficient cumulative impact analysis.
    California chiefly argued that the FAA needed to create
    an environmental impact statement (EIS) because a
    California Environmental Impact Report prepared under the
    California Environmental Quality Act (CEQA) found that
    the proposed Project could result in significant impacts on
    air quality, greenhouse gas, and noise. First, California
    argued the FAA should have refuted the CEQA findings
    regarding air quality impacts. The thresholds discussed in
    the CEQA analysis that California pointed to are those
    established by the South Coast Air Quality Management
    District (SCAQMD). The panel held by the SCAQMD’s
    own assessment, the Project will comply with federal and
    state air quality standards. Second, California argued that
    the FAA should have refuted the CEQA findings regarding
    greenhouse gas impacts. The panel held that California did
    not refute the EA’s rationale for why it found no significant
    impact of the Project’s greenhouse gas emissions on the
    environment, and did not articulate what environmental
    impact may result from the Project’s emissions standards
    exceeding the SCAQMD threshold. The panel also rejected
    California’s noise concerns. The panel concluded that
    California failed to raise a substantial question as to whether
    6           CENTER FOR COMMUNITY ACTION V. FAA
    the Project may have a significant effect on the environment
    so as to require the creation of an EIS.
    Petitioners alleged certain errors related to the FAA’s
    calculations regarding truck trip emissions generated by the
    Project. First, the panel held that there was no authority to
    support petitioners’ assertion that the EA had to use the same
    number of truck trips that the CEQA analysis used, or that
    the FAA was required to explain the difference. The panel
    held further that petitioners failed to show arbitrariness or
    capriciousness in the EA’s truck trip calculation
    method. Second, petitioners provided no reason to believe
    that the EA did not correctly analyze total truck trips
    emissions. Finally, the panel rejected petitioners’ argument
    that the record contained an inconsistency concerning the
    number of daily truck trips calculated by the FAA.
    Finally, petitioners asserted that the FAA failed to
    consider the Project’s ability to meet California state air
    quality and federal ozone standards. First, the CCA argued
    that the EA failed to assess whether the Project met the air
    quality standards set by the California Clean Air Act. The
    panel held that CCA failed to articulate a potential violation
    of the Act stemming from the Project. More importantly, the
    EA did discuss California air quality law. Second, CCA
    provided no reason to believe that the Project threatened a
    violation of the federal ozone standards. Finally, the panel
    rejected petitioners’ argument that the EA failed to assess
    whether the Project met California’s greenhouse gas
    emissions standards.
    Judge Rawlinson dissented. She wrote that the case
    reeked of environmental racism, defined as “the creation,
    construction, and enforcement of environmental laws that
    have a disproportionate and disparate impact upon a
    CENTER FOR COMMUNITY ACTION V. FAA             7
    particular race.” San Bernardino County, California, is one
    of the most polluted corridors in the United States, and the
    site of the Project was populated overwhelmingly by people
    of color. Judge Rawlinson agreed with the petitioners that
    the difference between the State of California’s conclusion
    of significant environmental impacts of the Project under
    CEQA and the FAA’s conclusion of no significant impact
    could be explained by the FAA’s failure to take the requisite
    “hard look” at the Project as required by NEPA. Judge
    Rawlinson wrote that the EA was deficient in numerous
    ways, and this EA would not prevail if the Project were
    located near the home of the multibillionaire owner of
    Amazon.

    OPINION
    SILER, Circuit Judge:
    Petitioners Center for Community Action and
    Environmental Justice, Sierra Club, Teamsters Local 1932,
    Shana Saters, and Martha Romero (collectively, CCA) and
    the State of California (collectively, Petitioners) ask us to
    review Respondent Federal Aviation Administration’s
    (FAA) Record of Decision, which found no significant
    environmental impact stemming from the construction and
    operation of an air cargo facility (Project) at the San
    Bernardino International Airport (Airport). To comply with
    their duties under the National Environmental Policy Act
    (NEPA), the FAA issued an Environmental Assessment
    (EA) that evaluated the environmental effects of the Project.
    In an effort to prevent execution of the Project, Petitioners
    allege error in the EA and the FAA’s finding of no
    significant environmental impact. Because Petitioners have
    not established the findings in the EA to be arbitrary and
    capricious, we deny the petition.
    I. Background
    The Airport is a public airport located in San Bernardino
    County, California. The Airport is currently under the
    control of Respondent/Intervenor San Bernardino
    International Airport Authority (SBIAA), a joint powers
    authority consisting of San Bernardino County and some
    surrounding cities, including San Bernardino.
    Hillwood Enterprises, L.P. (Hillwood), an affiliate of
    private developer Respondent/Intervenor Eastgate Bldg 1,
    LLC (Eastgate), has served as the Master Developer of the
    non-aviation portions of the Airport. Eastgate, Hillwood,
    10          CENTER FOR COMMUNITY ACTION V. FAA
    and the SBIAA possess an “Exclusive Right to Negotiate
    Agreement” providing for extensive due diligence and
    entitlement work on the Project. The Project is to develop
    the Eastgate Air Cargo Facility, which includes the
    development and operation of a 658,000-square-foot sort,
    distribution, and office building that would be operated by
    third-party air carriers transporting cargo to and from the
    Airport.
    Because the SBIAA has received federal funding for
    previous Airport projects, the Project’s proponents sought
    the FAA’s approval to comply with 
    49 U.S.C. § 47107
    (a)(16) of the Airport and Airway Improvement Act.
    Among other requirements, the Act requires the SBIAA to
    “maintain a current layout plan of the airport” with any
    revisions subject to the FAA’s review.         
    49 U.S.C. § 47107
    (a)(16)(B)-(D).
    The FAA’s review of the Project under its own statutory
    scheme triggers its duties under NEPA, 
    42 U.S.C. §§ 4321
    –
    4370m. In part, NEPA provides that “all agencies of the
    Federal Government shall . . . include in every
    recommendation or report on . . . major Federal actions
    significantly affecting the quality of the human environment,
    a detailed statement by the responsible official on . . . the
    environmental impact of the proposed action[.]” 
    Id.
     §
    4332(2)(C)(i).
    After reviewing the Project’s potential environmental
    impacts, the FAA issued a Record of Decision, which
    included its Final EA and Finding of No Significant Impact.
    CENTER FOR COMMUNITY ACTION V. FAA                     11
    See 
    40 C.F.R. § 1508.9
    (a) (2019) 1 (“Environmental
    assessment[] [m]eans a concise public document for which
    a Federal agency is responsible that serves to[] [b]riefly
    provide sufficient evidence and analysis for determining
    whether to prepare an environmental impact statement or a
    finding of no significant impact[ and] [a]id an agency’s
    compliance with [NEPA] when no environmental impact
    statement is necessary[.]”); 
    40 C.F.R. § 1508.13
     (2019)
    (“Finding of no significant impact means a document by a
    Federal agency briefly presenting the reasons why an action,
    not otherwise excluded . . . , will not have a significant effect
    on the human environment and for which an environmental
    impact statement therefore will not be prepared. It shall
    include the environmental assessment or a summary of it and
    shall note any other environmental documents related to
    it[.]”); 
    40 C.F.R. § 1501.3
    (a) (“An [environmental]
    assessment is not necessary if the agency has decided to
    prepare an environmental impact statement.”). Here, the
    Petitioners challenge the FAA’s finding of no significant
    impact.
    The parties agree that the FAA’s Record of Decision
    constitutes “an order issued by” the FAA under “part B
    [which encompasses 
    49 U.S.C. § 47107
    (a)(16)]” through
    which Petitioners “may apply for review . . . in the court of
    appeals of the United States for the circuit in which the
    person resides or has its principal place of business.” 49
    1
    The pertinent NEPA regulations were amended in February 2020, after
    the rendering of the EA and Finding of No Significant Impact at issue in
    this case. So, the pre-amended regulations apply here, see 
    40 C.F.R. § 1506.13
    , although no party has suggested that the difference in substance
    between the pre-amended and amended versions affects the outcome of
    this case.

    U.S.C. § 46110(a); see Barnes v. Fed. Aviation Admin., 
    865 F.3d 1266
    , 1268–70 (9th Cir. 2017).
    II. Discussion
    A. General Standards of Review
    “NEPA requires that a federal agency consider every
    significant aspect of the environmental impact of a proposed
    action . . . [and] inform the public that it has indeed
    considered environmental concerns in its decisionmaking
    process.” Earth Island Inst. v. United States Forest Serv.,
    
    351 F.3d 1291
    , 1300 (9th Cir. 2003) (simplified). To
    accomplish this, NEPA “imposes procedural requirements
    designed to force agencies to take a ‘hard look’ at
    environmental consequences.”         
    Id.
     (simplified).     As
    mentioned, the FAA here decided to issue an EA and a
    Finding of No Significant Impact. Although an EA “need
    not conform to all the requirements of an EIS [i.e.,
    Environmental Impact Statement], it must be sufficient to
    establish the reasonableness of the decision not to prepare an
    EIS.” Cal. Trout v. F.E.R.C., 
    572 F.3d 1003
    , 1016 (9th Cir.
    2009) (simplified). “In reviewing an agency’s finding that a
    project has no significant effects, courts must determine
    whether the agency has met NEPA’s hard look requirement,
    ‘based [its decision] on a consideration of the relevant
    factors, and provided a convincing statement of reasons to
    explain why a project’s impacts are insignificant.’” Bark v.
    United States Forest Serv., 
    958 F.3d 865
    , 869 (9th Cir. 2020)
    (simplified).
    “The statement of reasons is crucial to determining
    whether the agency took a ‘hard look’ at the potential
    environmental impact of a project.” Blue Mountains
    Biodiversity Project v. Blackwood, 
    161 F.3d 1208
    , 1212 (9th
    Cir. 1998) (simplified). “An EIS must be prepared if
    CENTER FOR COMMUNITY ACTION V. FAA               13
    substantial questions are raised as to whether a project . . .
    may cause significant degradation of some human
    environmental factor.” 
    Id.
     (simplified). “Thus, to prevail on
    a claim that the [agency] violated its statutory duty to prepare
    an EIS, a plaintiff need not show that significant effects will
    in fact occur.” 
    Id.
     (simplified). “It is enough for the plaintiff
    to raise substantial questions whether a project may have a
    significant effect’ on the environment.” 
    Id.
     (simplified).
    “Judicial review of agency decisions under [NEPA] is
    governed by the Administrative Procedure Act, which
    specifies that an agency action may only be overturned when
    it is ‘arbitrary, capricious, an abuse of discretion, or
    otherwise not in accordance with law.’” Earth Island, 
    351 F.3d at 1300
     (simplified). “An agency action is arbitrary and
    capricious if the agency has: relied on factors which
    Congress has not intended it to consider, entirely failed to
    consider an important aspect of the problem, offered an
    explanation for its decision 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.” Bark, 958 F.3d at 869 (simplified). “An
    agency’s factual determinations must be supported by
    substantial evidence.” Id. (simplified).
    As the “party challenging the administrative decision,”
    Petitioners “bear[] the burden of persuasion” here. See J.W.
    ex rel., J.E.W. v. Fresno Unified Sch. Dist., 
    626 F.3d 431
    ,
    438 (9th Cir. 2010). We have upheld an agency decision
    when there was no evidence “which compelled a different
    conclusion” or “any evidence that [the agency] considered
    impermissible factors.” George v. Bay Area Rapid Transit,
    
    577 F.3d 1005
    , 1011 (9th Cir. 2009) (citing City of Olmsted
    Falls, Ohio v. FAA, 
    292 F.3d 261
    , 271 (D.C. Cir. 2002)). As
    the D.C. Circuit has stated, “even assuming the [agency]
    14          CENTER FOR COMMUNITY ACTION V. FAA
    made missteps[,] the burden is on petitioners to demonstrate
    that the [agency’s] ultimate conclusions are unreasonable.”
    City of Olmsted Falls, 
    292 F.3d at 271
    ; see also San Luis
    Obispo Mothers for Peace v. U.S. Nuclear Regulatory
    Comm’n, 
    789 F.2d 26
    , 37 (D.C. Cir. 1986) (“[T]he party
    challenging an agency’s action as arbitrary and capricious
    bears the burden of proof.” (citing Nat’l Ass’n of Regul. Util.
    Comm’rs v. FCC, 
    746 F.2d 1492
    , 1502 (D.C. Cir. 1984))).
    B. Study Areas
    In evaluating the environmental consequences of the
    project, the FAA generally utilized two “study areas”—the
    General Study Area and the Detailed Study Area. The
    General Study Area “is defined as the area where both direct
    and indirect impacts may result from the development of the
    Proposed Project.” The Detailed Study Area, on the other
    hand, “is generally defined as the areas where direct physical
    impacts may result from the Proposed Project[.]” The
    General Study Area’s “purpose . . . is to establish the study
    area for the quantification of impacts to resource categories
    that involve issues that are regional in scope and scale,
    including noise, land use, socioeconomic impacts, and
    Section 4(f) and 6(f) resources.” The Detailed Study Area’s
    purpose, meanwhile, “is to establish the study area for
    environmental considerations that deal with specific and
    direct physical construction or operational issues that
    directly affect natural resources such as water resources, air
    quality, and hazardous materials.” The CCA’s general
    argument here is that the FAA’s defined geographical
    boundaries encompassing the study areas did not
    CENTER FOR COMMUNITY ACTION V. FAA                      15
    appropriately capture the true environmental impacts of the
    project. 2
    In attacking the parameters of the study areas, the CCA
    repeatedly asserts that the FAA did not conform its study
    areas to the FAA’s Order 1050.1F Desk Reference. Most, if
    not all, of the CCA’s improper study areas arguments are
    derived by evaluating the conformity of the findings in the
    EA to the guidance provided by the Desk Reference. But the
    CCA’s arguments in this regard are unavailing because the
    CCA does not dispute the fact that the Desk Reference does
    not serve as binding guidance upon the FAA: “This Desk
    Reference may be cited only as a reference for the guidance
    it contains, and may not be cited as the source of
    requirements under laws, regulations, Executive Orders,
    DOT or FAA directives, or other authorities.” FAA 1050.1F
    Desk Reference, Introduction (July 2015). 3
    We “review an agency’s alleged noncompliance with an
    agency pronouncement only if that pronouncement actually
    has the force and effect of law.” W. Radio Servs. Co., Inc. v.
    2
    As an initial matter, although the FAA argues that most of the CCA’s
    arguments are not preserved for the CCA’s failure to exhaust them, it
    appears the CCA sufficiently exhausted the arguments they present here.
    See Lands Council v. McNair, 
    629 F.3d 1070
    , 1076 (9th Cir. 2010) (“[A]
    claimant need not raise an issue using precise legal formulations, as long
    as enough clarity is provided that the decision maker understands the
    issue raised. Accordingly, alerting the agency in general terms will be
    enough if the agency has been given ‘a chance to bring its expertise to
    bear to resolve [the] claim.’” (citation omitted)).
    3
    The applicable Desk Reference at the time of the FAA’s EA was the
    July 2015 version, not the February 2020 version the CCA relies upon.
    In any event, no party has suggested that the difference in substance
    between the pre-amended and amended versions affects the outcome of
    this case.

    The only argument the CCA makes to support its
    assertion that the Desk Reference is relevant is that the FAA
    itself pointed to the Desk Reference as a reference in
    analyzing the environmental consequences of the Project.
    Yet without more, these references are insufficient to “bind”
    the FAA here. See W. Radio, 79 F.3d at 902. References to
    the Desk Reference “cannot bind” the FAA “to a Manual or
    Handbook that is neither promulgated pursuant to
    congressional procedure nor contemplated in a statute.” Id.
    And “[m]ere incorporation does not convert a procedural
    guideline into a substantive regulation.” Id. We therefore
    cannot review the CCA’s allegations that the EA’s study
    areas are deficient per the Desk Reference.
    The FAA’s nonadherence to the Desk Reference cannot
    alone serve as the basis for holding that the FAA did not take
    a “hard look” at the environmental consequences of the
    Project. Instead, the CCA must show that the FAA’s
    nonadherence to the Desk Reference has some sort of EA
    CENTER FOR COMMUNITY ACTION V. FAA             17
    significance aside from simply failing to follow certain Desk
    Reference instructions. But the CCA has not done so here.
    The CCA first argues that the General Study Area is
    deficient because the FAA failed to create individualized
    study areas for individual impact categories (i.e.,
    individualized study areas for the Project’s effects on air
    quality, noise, water, etc.). The CCA, however, has
    conceded that “[t]he EA may rely on one sufficiently large
    study area to address all . . . impacts.” And the CCA does
    not explain why the circumstances of the Project dictated
    different study areas based on different environmental
    impacts, apart from summarily concluding that it did. On
    the other hand, the FAA justified the parameters of its
    General Study Area, in part, as being based on the region
    around the Airport affected by noise, the region considered
    to be Airport property, and the region north of the Airport
    through which vehicle traffic was expected to flow to and
    from the project site. Without an explanation as to why a
    more individualized study area per environmental impact
    was needed, the CCA raises no substantial questions as to
    whether the Project may cause significant degradation of
    some environmental factor, and there is no reason to believe
    that the FAA’s use of the General Study Area as a general
    baseline to evaluate multiple environmental impacts was an
    abrogation of its responsibility of taking a hard look at the
    environmental consequences of the Project. See J.W., 
    626 F.3d at 438
    ; George, 
    577 F.3d at 1011
    .
    Next, the CCA generally attacks the EA’s consideration
    of the impact of the Project on air quality. The CCA argues
    that the General Study Area does not appropriately
    encompass the effect of vehicle traffic on air quality because
    “the FAA’s air quality analysis only captures air quality
    impacts to an area that is less than five miles wide and four
    18          CENTER FOR COMMUNITY ACTION V. FAA
    miles long, even though many air quality impacts occur
    outside the General Study Area.”
    These assertions, however, are belied by the fact that the
    FAA did evaluate air quality impacts outside of the General
    Study Area and provided a detailed explanation of its
    methodology in that regard. There is no indication from the
    EA that the FAA limited its consideration of air quality
    impacts within the geographical parameters of the General
    Study Area only. For example, throughout the EA, the FAA
    continuously evaluates the impact of vehicular emissions
    and the Project in general on the air quality within the South
    Coast Air Basin. The Basin encompasses a geographical
    area greater than the General Study Area and is overseen by
    the South Coast Air Quality Management District
    (SCAQMD) under the direction of the California Air
    Resources Board to ensure air pollutant levels adhere to state
    and federal standards. In ascertaining the impact of
    vehicular emissions on air quality, the FAA considered the
    “[a]verage truck trip length for delivery trucks,” and the
    average 64.25-mile length truck trip, goes far beyond the
    “five-by-four mile General Study Area[.]” Moreover:
    The air quality analysis for this EA includes
    direct and indirect emissions inventories, as
    well as air dispersion modeling for landside
    sources (area, energy, and mobile) and
    airside sources (aircraft operations and GSE).
    Mass emissions inventories were prepared
    for both construction and operations of the
    Proposed Project and No Action Alternative.
    The criteria pollutant emission inventories
    developed as part of this EA used standard
    industry software/models and federal, state,
    CENTER FOR COMMUNITY ACTION V. FAA             19
    and locally approved methodologies.
    Emissions of regulated pollutants were
    calculated to determine if the impacts to air
    quality from the Proposed Project would
    potentially be significant under the federal
    Clean Air Act of 1970, as amended. For
    those Proposed Project pollutant emissions
    that exceeded mass emissions thresholds,
    dispersion-modeling       analyses      were
    performed to determine if the Proposed
    Project would contribute to an exceedance of
    a [National Ambient Air Quality Standard].
    So contrary to what the CCA suggests, the FAA did go
    beyond the General Study Area in ascertaining the true scope
    of both the Project’s emissions and the impact of those
    emissions.
    The CCA also argues that the General Study Area does
    not appropriately encompass the socioeconomic impacts of
    the Project. Specifically, the CCA argues that “the General
    Study Area is significantly smaller than the local population
    centers for the Cities of San Bernardino, Highland,
    Redlands, and unincorporated San Bernardino County, even
    though Eastgate is located in or borders each of these areas.”
    Yet, as is the case with most of their study area arguments,
    the CCA fails to articulate exactly why the FAA needed to
    expand the General Study Area to include more of the local
    population centers than it already did. Simply summarily
    asserting that the FAA should have expanded its General
    Study Area to include more people based on the guidance
    offered in the nonbinding Desk Reference is insufficient to
    render the FAA’s chosen socioeconomic General Study
    20          CENTER FOR COMMUNITY ACTION V. FAA
    Area arbitrary when it was based, in part, on expected noise
    and vehicle traffic considerations.
    The CCA’s next argument is that the EA deficiently
    examines whether “the proposed action or alternative(s)
    creates impacts that are incompatible with existing and/or
    future planned uses in the study area.” The only specific
    argument the CCA makes here, however, is that the General
    Study Area “is not big enough to be able to evaluate whether
    the Project navigates truck trips through residential
    neighborhoods . . . [so] it is . . . far too small to determine
    whether the Project will lead to any incompatible land uses
    from truck traffic.” But the parameters of the General Study
    Area were based, in part, on “the neighborhoods north of the
    Airport through which employee vehicle and truck traffic is
    expected to flow to and from the Proposed Project site[.]”
    The CCA has not pointed to anything suggesting that traffic
    stemming from the Project is expected to flow to residential
    neighborhoods outside of those parameters. Without more,
    the CCA’s argument here is meritless.
    Finally, the CCA attacks the legitimacy of the Detailed
    Study Area examined by the FAA. More specifically, the
    CCA argues that the FAA failed to comply with the Desk
    Reference’s instruction that the FAA must consider the
    “existing contaminated sites at the proposed project site or
    in the immediate vicinity of a project site” and include “local
    disposal capacity for solid and hazardous wastes generated
    from the proposed action or alternative(s).” But with respect
    to the two hazardous material sites the FAA allegedly failed
    to properly evaluate, the CCA has not explained why those
    sites fall within the “proposed project site or in the
    immediate vicinity of a project site” when they fall “more
    than 1.5 miles and 0.75 miles, respectively, from the
    [Project] Site.” Distance is relative, and what may seem
    CENTER FOR COMMUNITY ACTION V. FAA             21
    sufficiently close for consideration to a non-expert may not
    in fact be so. Without an explanation of why that is the case
    here, we cannot conclude that the FAA acted arbitrarily in
    purportedly omitting those two sites from the Detailed Study
    Area.
    Additionally, although the CCA harps on the exclusion
    of certain sites from the Detailed Study Area where “past
    waste management [and] disposal practices” may have
    contaminated the surrounding soil and groundwater, the
    CCA ignores the FAA’s consideration of the remediation
    and monitoring efforts at these sites in determining that they
    do not present any notable risks. This remediation and
    monitoring effort also applies to the two hazardous materials
    sites, mentioned above, that the CCA highlights.
    Lastly on this point, the CCA asserts that “the FAA does
    not explain how and why on an active Superfund site this
    tiny section encompasses the entire geographic area that may
    be directly or indirectly impacted by hazardous materials
    from this Project” and “fails to account for the common
    sense reality that wind and trucks carrying materials also
    transport dust containing hazardous materials outside the
    Detailed Study Area and throughout the Project site and
    beyond.” But the CCA fails to point to any evidence to
    support its assertion that the Detailed Study Area failed to
    encompass the true scope of the impact of hazardous
    materials. Cf. Bark, 958 F.3d at 870–71.
    In sum, the CCA has not carried its burden of showing
    missteps on the part of the FAA. Without the CCA meeting
    this burden, we cannot conclude that a substantial question
    has been raised as to whether the Project may have a
    significant effect on the environment, or that the FAA skirted
    22          CENTER FOR COMMUNITY ACTION V. FAA
    its duty of taking a “hard look” at the environmental
    consequences of the Project.
    C. Cumulative Impacts
    The CCA next asserts that the FAA failed to sufficiently
    consider the cumulative impacts of the Project. This court
    has discussed NEPA’s requirement of a cumulative impacts
    analysis as follows:
    NEPA always requires that an environmental
    analysis for a single project consider the
    cumulative impacts of that project together
    with “past, present and reasonably
    foreseeable future actions.” Cumulative
    impact “is the impact on the environment
    which results from the incremental impact of
    the action when added to other past, present,
    or reasonably foreseeable future actions.” . . .
    [R]egulations specifically admonish agencies
    that cumulative impacts “can result from
    individually     minor     but    collectively
    significant actions taking place over a period
    of time.”
    We have recognized that even EAs, the less
    comprehensive of the two environmental
    reports envisioned by NEPA, must in some
    circumstances include an analysis of the
    cumulative impacts of a project. . . . An EA
    may be deficient if it fails to include a
    cumulative impact analysis or to tier to an
    EIS [i.e., Environmental Impact Statement]
    that reflects such an analysis.
    CENTER FOR COMMUNITY ACTION V. FAA            23
    Native Ecosystems Council v. Dombeck, 
    304 F.3d 886
    , 895–
    96 (9th Cir. 2002) (citations omitted) (emphasis removed).
    This court in Bark expounded on the requisite cumulative
    impact analysis:
    [I]n considering cumulative impact, an
    agency must provide some quantified or
    detailed information; . . . [g]eneral statements
    about possible effects and some risk do not
    constitute a hard look absent a justification
    regarding why more definitive information
    could not be provided. This cumulative
    analysis ‘must be more than perfunctory; it
    must provide a useful analysis of the
    cumulative impacts of past, present, and
    future projects.      We have held that
    cumulative impact analyses were insufficient
    when they discusse[d] only the direct effects
    of the project at issue on [a small area] and
    merely contemplated other projects but had
    no quantified assessment of their combined
    impacts.
    958 F.3d at 872 (simplified).
    Absent a cumulative impact approach, agencies could
    avoid required, comprehensive environmental review by
    undertaking many small actions, each of which has an
    insignificant impact but which together have a substantial
    impact; the process would be subject to “the tyranny of small
    decisions.” Kern v. U.S. Bureau of Land Mgmt., 
    284 F.3d 1062
    , 1078 (9th Cir 2002). The “rationale for evaluating
    cumulative impacts together is to prevent an agency from
    ‘dividing a project into multiple actions’ to avoid a more
    24           CENTER FOR COMMUNITY ACTION V. FAA
    thorough consideration of the impacts of the entire project.”
    Tinian Women Ass’n v. U.S. Dep’t of the Navy, 
    976 F.3d 832
    ,
    838 (9th Cir. 2020) (quoting Native Ecosystems Council, 
    304 F.3d at 894
    ). Cumulative impacts that result from
    individually minor but collectively significant actions are the
    crux of what the regulations implementing NEPA seek to
    avoid. High Sierra Hikers Ass’n v. Blackwell, 
    390 F.3d 630
    ,
    645–46 (9th Cir. 2004) (citing 
    40 C.F.R. § 1508.7
    ).
    For cumulative impact analysis to be adequate, “an
    agency must provide some quantified or detailed
    information.” Bark, 958 F.3d at 872. While the agency is
    required to take a “hard look” at the cumulative impacts of a
    project, that requirement is about whether the agency
    adequately explained the potential effects and risks, not
    whether a petitioner disagrees with those explanations. See
    id. (“General statements about possible effects and some risk
    do not constitute a hard look absent a justification regarding
    why more definitive information could not be provided.”
    (simplified)). So a cumulative impact analysis is insufficient
    if it discusses only “the direct effects of the project at issue
    on [a small area]” or “merely contemplate[] other projects
    but had no quantified assessment of their combined
    impacts.” Id. (simplified).
    Petitioners alleging a failure to adequately consider
    cumulative impacts “do[] not face an ‘onerous’ burden” and
    they ‘need not show what cumulative impacts would
    occur.’” Tinian Women Ass’n, 976 F.3d at 838 (quoting Te-
    Moak Tribe of W. Shoshone of Nev. v. U.S. Dep’t of Interior,
    
    608 F.3d 592
    , 605 (9th Cir. 2010)). Instead, petitioners
    “need[] to show ‘only the potential for cumulative impact.’”
    
    Id.
     (quoting Te-Moak Tribe, 
    608 F.3d at 605
    ).
    CENTER FOR COMMUNITY ACTION V. FAA              25
    The CCA first argues that the FAA only considered past,
    present, and reasonably foreseeable projects within the
    General Study Area and should have expanded its
    assessment to include an additional 80-plus projects. But the
    only potential cumulative environmental impact resulting
    from these projects that the CCA asserts the FAA failed to
    consider is the fact that “these 80[-plus] projects taken
    together will result in a massive 168,493 average daily trips
    in the first year of project operations.” However, the record
    shows that the FAA specifically “account[ed] for the traffic
    generated by these 80-plus projects” for “purposes of
    identifying cumulative traffic volumes.”
    Seemingly conceding this point, the CCA pivots to its
    argument that the FAA should have considered the 80-plus
    projects’ effects on unidentified “other impact areas.” But
    the CCA fails to identify what “other” potential cumulative
    impacts that the FAA failed to consider with the 80-plus
    projects. Indeed, in other cases where we have ordered an
    agency to reconsider its cumulative impacts analysis, we
    have relied on the petitioner to raise the potential cumulative
    impact affected. See Bark, 958 F.3d at 872–73 (“The
    [agency]’s failure to engage with the other projects identified
    by Appellants leaves open the possibility that several small
    forest management actions will together result in a loss of
    suitable owl habitat. . . . [W]e have no basis in the record to
    assess whether the [agency] has taken the necessary steps to
    consider this possibility.” (emphasis added)); Klamath-
    Siskiyou, 387 F.3d at 996–97 (holding that a cumulative
    impact analysis was inadequate where the EA did not
    address “the potential for a combined effect from the
    combined runoffs” from two separate minerals or the effect
    of the loss of the spotted owl’s habitat on the region that the
    petitioner identified); Kern, 284 F.3d at 1066–67, 1078
    26          CENTER FOR COMMUNITY ACTION V. FAA
    (holding that a cumulative impact analysis was insufficient
    where the revised EA did not “analyz[e] the impact of
    reasonably foreseeable future timber sales within the
    District” that the petitioner identified).
    While the petitioners in the aforementioned cases
    identified potential cumulative impacts that the agency did
    not address, the CCA here summarily concludes that the
    FAA needed to conduct a better cumulative impacts
    analysis. The fact that the CCA cannot identify any potential
    cumulative impacts that the FAA failed to consider suggests
    that there are none. While the burden on petitioners to
    identify potential cumulative impacts is not “onerous,”
    Tinian Women Ass’n, 976 F.3d at 838, the CCA still “bears
    the burden of persuasion,” J.W. ex rel., J.E.W. v. Fresno
    Unified Sch. Dist., 
    626 F.3d 431
    , 438 (9th Cir. 2010). And
    merely stating that the FAA needed to consider the 80-plus
    projects’ effect on unidentified “other impact areas” does not
    carry the CCA’s burden.
    To the extent that the CCA implicitly suggests that the
    FAA should have considered the 80-plus other projects’
    cumulative impact on air emissions, it failed to provide
    support for that view. It is undisputed that the FAA
    considered 20-plus projects in analyzing the cumulative
    impacts of the Project on air quality. And so long as the
    agency provides a sufficient explanation, we generally
    “defer to an agency’s determination of the scope of its
    cumulative effects review.” Neighbors of Cuddy Mountain
    v. Alexander, 
    303 F.3d 1059
    , 1071 (9th Cir. 2002). The only
    evidence that CCA points to is a California Environmental
    Quality Act (CEQA) report that found air pollutant
    emissions associated with the Project would result in
    “cumulatively considerable significant impact” with respect
    to construction activity and operational activity. But the
    CENTER FOR COMMUNITY ACTION V. FAA            27
    CEQA report does not expressly attribute its cumulative
    impact findings to the 80-plus projects identified by the CCA
    in reaching its conclusion. Nor does the CCA contend that
    the CEQA report found a cumulative impact on air quality
    only because it considered the 80-plus projects. Moreover,
    the FAA specifically considered the cumulative air impact
    of construction and operation of the Project. The FAA
    provided,
    [W]ith respect to NOx and VOC emissions,
    because the emissions are directly accounted
    for in the SIP [State Implementation Plan]
    emissions budget, the Propose[d] Project
    would conform to the SIP that allows for
    attainment of the ozone NAAQS. The
    estimated annual CO emissions for 2024
    operations was found to exceed the de
    minimis thresholds. However, the 2012
    AQMP does not provide conformity budgets
    for CO emissions. Therefore, air dispersion
    modeling was conducted to determine if the
    Proposed Project impacts would result in an
    exceedance of the 1- and 8-hour CO
    NAAQS. The air dispersion modeling found
    that the operation of the Proposed Project
    would result in ground level concentrations
    that do not exceed the relevant NAAQS.
    Additionally, emissions of SOx, PM, and Pb
    are below de minimis levels. Emissions
    associated with construction and operation of
    the Proposed Project would not cumulatively
    cause an exceedance of the NAAQS or
    contribute to an increase in frequency or
    severity of an existing NAAQS violation.
    28           CENTER FOR COMMUNITY ACTION V. FAA
    The CCA has not argued that the difference between the
    CEQA’s and the FAA’s analysis was caused by the 80-plus
    projects that the CCA claims FAA needed to analyze. In
    other words, the CCA has not shown that the FAA’s
    cumulative impact analysis on air quality would have been
    potentially different if it considered the 80-plus projects. See
    Te-Moak Tribe, 
    608 F.3d at 605
     (petitioners “must show . . .
    the potential for cumulative impact.” (emphasis added)).
    Thus, the CCA hasn’t carried its burden to show why the
    FAA was required to consider the 80-plus projects in
    conducting the cumulative impacts analysis on air pollution.
    The CCA also argues that “the EA does not disclose
    specific, quantifiable data about the cumulative effects of
    related projects, and it does not explain why objective data
    about the projects could not be provided.” First, the CCA’s
    belief that the FAA must provide quantifiable data is based
    on a misreading of our precedent. While the CCA suggests
    that Klamath-Siskiyou requires “an EA . . . [to] provide an
    ‘objective quantification of the impacts,’ or at the very least
    an explanation for ‘why objective data cannot be
    provided[,]’” what “[a] proper consideration of the
    cumulative impacts of a project requires [is] some quantified
    or detailed information[.]” Klamath-Siskiyou, 387 F.3d at
    993 (simplified). So despite what the CCA argues,
    quantified data in a cumulative effects analysis is not a per
    se requirement.
    And in that vein, the FAA did provide “detailed
    information” about cumulative impacts here. The only
    specific deficiency with this information that the CCA
    alleges is the EA’s cumulative air quality impact discussion.
    The CCA insists that the FAA did not sufficiently support its
    conclusion that “cumulative emissions are not expected to
    contribute to any potential significant air quality impacts”
    CENTER FOR COMMUNITY ACTION V. FAA             29
    because the EA makes no “references to combined PM or
    NOx emissions from the 26 projects” falling within the
    General Study Area. Again though, the CCA points to
    nothing to support its assertion that the FAA needed to
    evaluate cumulative air quality impact in this way. More
    importantly, the CCA offers no evidence to substantiate its
    suggestion that the FAA’s rationale for its cumulative effects
    conclusions, which does include a discussion of PM and
    NOx emissions, is deficient. See Bark, 958 F.3d at 872.
    Thus, the CCA and the state’s conclusory criticisms of
    the EA’s failure to conduct a more robust cumulative air
    impact analysis amount to disagreements with the results,
    not procedures. We find no reason to find that the FAA
    conducted a deficient cumulative impact analysis.
    D. California’s Arguments for the Preparation of an
    EIS
    California agrees with the CCA that the FAA should
    have prepared an EIS.
    California chiefly asserts that the FAA needed to create
    an EIS because a California Environmental Impact Report
    (EIR) prepared under CEQA found that “[t]he proposed
    Project could result in significant impacts [on] . . . Air
    Quality, Greenhouse Gas, and Noise[.]” Because CEQA
    review “closely approximat[es]” review under NEPA,
    California argues, “NEPA requires the FAA to meaningfully
    address the substantial questions raised by the prior CEQA
    analysis that concluded the Project would cause significant
    and unavoidable environmental impacts.”
    California does not go so far as to argue that an EA under
    NEPA must reach the same conclusion as the CEQA
    analysis. California’s argument does assume, however, that
    30           CENTER FOR COMMUNITY ACTION V. FAA
    if a CEQA analysis finds significant environmental effects
    stemming from a project, a NEPA analysis must explain
    away this significance. But “[d]efendants [a]re not required
    to rely on the conclusion in the CEQA EIR because CEQA
    and NEPA are different statutes with different
    requirements.” Save Strawberry Canyon v. United States
    Dept. of Energy, 
    830 F. Supp. 2d 737
    , 749 (N.D. Cal. 2011).
    Indeed, “California courts have recognized that CEQA
    obligations may exceed those imposed by NEPA.” City of
    South Pasadena v. Goldschmidt, 
    637 F.2d 677
    , 680 n.4 (9th
    Cir. 1981) (citation omitted). So instead of simply relying
    on the conclusions in the CEQA report, California must
    identify specific findings in that report that it believes raise
    substantial questions about environmental impact. But
    California identifies only a few such findings, and none of
    them raise substantial questions as to whether the Project
    may have a significant effect on the environment.
    First, California argues the FAA should have refuted the
    CEQA findings regarding air quality impacts. According to
    California, the “Final EIR found that the construction of the
    Project would result in nitrogen oxides and PM emissions
    that exceed applicable local regional air quality thresholds
    based on additional mitigation, and that even after
    implementing recommended mitigation measures, the
    Project’s emissions from operations would exceed regional
    thresholds of significance for VOC, nitrogen oxides, carbon
    monoxide, and PM.” Furthermore, in the State’s view, the
    Final EIR found that “[n]o feasible mitigation measures have
    been identified that would reduce these emissions to levels
    that are less than significant.” The thresholds discussed in
    the CEQA analysis that California points to are those
    established by the SCAQMD.              The “SCAQMD is
    responsible for ensuring that federal and state air quality
    CENTER FOR COMMUNITY ACTION V. FAA              31
    standards are met within the Basin.” To that end, the
    SCAQMD “has adopted a series of Air Quality Management
    Plans (AQMPs) to meet the state and federal ambient air
    quality standards.”
    Noted within the EA is the fact that the SBIAA “initiated
    a formal request to the SCAQMD to determine if the mass
    emissions generated from the operation of the Proposed
    Project are within the General Conformity Budgets
    identified in the 2012 AQMP.”               Importantly, the
    SCAQMD’s response to the request states, “[i]n summary,
    based on our evaluation the proposed project will conform
    to the AQMP (i.e. project emissions are within AQMP
    budgets) and is not expected to result in any new or
    additional violations of the NAAQS or impede the projected
    attainment of the standards.” So by the SCAQMD’s own
    assessment, the Project will comply with federal and state air
    quality standards.
    Second, California argues that the FAA should have
    refuted the CEQA findings regarding greenhouse gas
    impacts. California claims that “the Final EIR determined
    that emissions from Project operations would exceed local
    air district thresholds, and that no feasible mitigation
    measures could reduce greenhouse gas emissions to levels
    that are less than significant.” According to the State, the
    Final EIR concluded that the “Project operations would
    create a significant cumulative impact to global climate
    change.” The CEQA analysis’s conclusion here appears to
    be based solely on the fact that greenhouse gas emissions are
    projected to exceed SCAQMD regional thresholds. But
    even if there was such a threat, California does not articulate
    why the presence of this one intensity factor requires the
    preparation of an EIS. See Wild Wilderness, 871 F.3d at 727
    (“One of these factors may demonstrate intensity sufficiently
    32          CENTER FOR COMMUNITY ACTION V. FAA
    on its own, although the presence of one factor does not
    necessarily do so.”); see also Native Ecosystems Council v.
    United States Forest Serv., 
    428 F.3d 1233
    , 1240 (9th Cir.
    2005) (“[I]t does not follow that the presence of some
    negative effects necessarily rises to the level of
    demonstrating a significant effect on the environment.”).
    Just as important, California does not refute the EA’s
    following rationale for why it found no significant impact of
    the Project’s greenhouse-gas emissions on the environment:
    The[ Project’s operational] levels of
    [greenhouse gas (GHG)] emissions increases
    would comprise less than 1 percent of both
    the U.S.-based GHG emissions and global
    GHG emissions (IPCC, 2014).
    . . . As noted by CEQ, “climate change is a
    particularly complex challenge given its
    global nature and inherent interrelationships
    among its sources, causation, mechanisms of
    action and impacts . . . .” Given the enormity
    of GHG emissions worldwide, the
    contributions of one project, such as that of
    the Proposed Project, are negligible. CEQ
    has also noted, “it is not currently useful for
    the NEPA analysis to attempt to link specific
    climatological changes, or the environmental
    impacts thereof, to the particular project or
    emissions, as such direct linkage is difficult
    to isolate and to understand.”
    . . . As previously stated, given the enormity
    of GHG emissions worldwide . . . , the
    CENTER FOR COMMUNITY ACTION V. FAA              33
    contributions of one project, such as the
    Proposed Project would comprise of less than
    1 percent of both the U.S.-based GHG
    emissions and global emissions (IPCC, 2014)
    . . . . The emissions generated from
    construction of the Proposed Project in 2019
    would be 0.0009 percent of the 2017
    California GHG inventory and even less for
    the duration of the 2020 construction.
    This rationale is not refuted by the CEQA analysis’s cursory
    assumption that a SCAQMD emissions threshold violation
    would even cause a significant environmental impact.
    California does not articulate what environmental impact
    may result from the Project’s emissions exceeding the
    SCAQMD threshold.
    Finally, California cites the noise findings issued in the
    CEQA analysis. The CEQA analysis found that “off-site
    transportation noise level increases at adjacent noise-
    sensitive residential homes are considered significant and
    unavoidable, but all other noise impacts are less than
    significant or can be mitigated to a level of less than
    significant.” So the only noise concern stemming from the
    CEQA analysis is that connected with off-site transportation
    at adjacent noise-sensitive residential homes. But the EA
    notes that the SBIAA plans on expanding its territory and
    acquiring adjacent properties to the airport as a noise
    mitigation measure.
    In sum, California fails to raise a substantial question as
    to whether the Project may have a significant effect on the
    environment so as to require the creation of an EIS. Cf. Am.
    Wild Horse Campaign v. Bernhardt, 
    963 F.3d 1001
    , 1008
    (9th Cir. 2020) (“NEPA regulations do not anticipate the
    34          CENTER FOR COMMUNITY ACTION V. FAA
    need for an EIS anytime there is some uncertainty, but only
    if the effects of the project are highly uncertain.”
    (simplified)).
    E. Truck Trips
    Next, Petitioners allege certain errors related to the
    FAA’s calculations regarding truck trips emissions
    generated by the Project.
    First, Petitioners argue that the EA fails to explain why
    its calculation for total truck trips is lower than the amount
    stated in the CEQA analysis. But Petitioners do not point to
    any authority to support their assertion that the EA had to
    use the same number of truck trips that the CEQA analysis
    used, or that the FAA was required to explain away this
    difference.
    More importantly, Petitioners fail to show arbitrariness
    or capriciousness in the EA’s truck trip calculation method.
    As the EA explains:
    The number of truck trips was determined by
    dividing the total number of packages
    arriving at the Project Site daily by the
    average package size and then dividing that
    by the number of packages that can fit into
    each truck (approximately 1,500 packages
    per truck). The Proposed Project would
    develop a package sorting facility, with truck
    trips limited to moving air cargo shipments to
    and from distribution centers. The Proposed
    Project would not result in truck trips to
    deliver packages from the Airport directly to
    homes in the community. In 2019, the
    Proposed Project would generate . . . 192
    CENTER FOR COMMUNITY ACTION V. FAA              35
    round trip truck trips. In 2024, the total
    average daily trips generated by the Proposed
    Project would be . . . 500 round trip truck
    trips.
    In contrast to the total amount of truck trips in 2019 and 2024
    that the EA calculated, the CEQA analysis determined that
    the respective 2019 and 2024 truck trip count would be 248
    and 652. California does not assert error in the FAA’s peak
    packages volume calculations, calculated to be 824,000 and
    2,145,000 in 2019 and 2024 respectively, which served as
    the basis for the FAA’s total truck trips calculation. In
    contrast, the CEQA analysis’s package volume calculations
    came out to be “1,030,877 per day during the peak season”
    for 2019 and “2,238,443 per day during peak season” for
    2024. It appears the CEQA analysis’s only basis for its truck
    trip numbers is the “data provided by the tenant[,]” so it is
    unclear how the CEQA analysis arrived at those numbers.
    But, if the CEQA analysis’s truck trip numbers were
    calculated in a similar way as the FAA’s, the slight
    difference in package volume could explain the slight
    difference in truck trip numbers and additionally lend
    credence to the FAA’s methodology for arriving at such a
    number, which, despite Petitioners’ contention, is clearly
    laid out as shown in the record.
    Petitioners do not argue that the EA’s methodology was
    improper or that the data the FAA relied on was erroneous.
    Petitioners argue only that the EA should have explained the
    differences in numbers reached by the CEQA analysis and
    the EA. But if Petitioners cannot even point to the CEQA
    analysis’s rationale for coming to its conclusion—seemingly
    because no explanation for that conclusion exists—it is
    unreasonable to insist that the FAA can.
    36          CENTER FOR COMMUNITY ACTION V. FAA
    Additionally, the FAA’s posited explanation for the
    difference in truck trips amounts as being a product of the
    CEQA analysis’s reliance on outdated data is not
    appropriately termed an impermissible post-hoc
    rationalization. “The rule barring consideration of post hoc
    agency rationalizations operates where an agency has
    provided a particular justification for a determination at the
    time the determination is made, but provides a different
    justification for that same determination when it is later
    reviewed by another body.” Independence Min. Co. v.
    Babbit, 
    105 F.3d 502
    , 511 (9th Cir. 1997) (citations omitted).
    In pointing out the differences in data used between the
    CEQA analysis and the EA, the FAA is not trying to justify
    anything it did; rather, the FAA is simply pointing out that
    the differences in data points could explain the different
    truck trip totals the agencies calculated.
    In sum, Petitioners do not raise a substantial question
    about whether the Project will have a significant
    environmental effect simply by pointing out the difference
    in the number of truck trips calculated as between the EA
    and CEQA analysis.
    Second, Petitioners argue that the EA considered only
    one-way trips, not roundtrips, in calculating truck trip
    emissions. Specifically, Petitioners assert that, because the
    “EA estimated emissions using CalEEMod, a program that
    estimates vehicle emissions based solely on one-way trips
    together with their one-way travel distances[,]”the FAA
    should have doubled the numbers it obtained when running
    the CalEEMod analysis in order to obtain correct emissions
    calculations. But, as the FAA states, “[u]pon completion of
    the CalEEMod modeling, further analysis was completed to
    calculate the total round trip truck traffic emissions that
    would be generated by the operation of the Proposed
    CENTER FOR COMMUNITY ACTION V. FAA           37
    Project.” Although the FAA does not appear to specifically
    articulate what further analysis was conducted, Petitioners
    do not refute the FAA’s following representations:
    Agency consultation included coordination
    with agencies and local jurisdictions such as
    the U.S. Environmental Protection Agency
    (U.S. EPA), South Coast Air Quality
    Management        District      (SCAQMD),
    California Air Resources Board (CARB), and
    the Southern California Association of
    Governments (SCAG) to review the Air
    Quality Protocol and modeling methodology.
    Modeling outputs (which included truck
    traffic data discussed by the commenter)
    from CalEEMod were thoroughly reviewed
    by the SCAQMD staff to ensure that all
    emissions (mobile, area, energy, etc.)
    generated by the Proposed Project were
    correctly calculated and those emissions
    generated would conform to the most recent
    Air Quality Management Plan (AQMP).
    Pet’rs ER 0414 (Pet’rs ER Vol. 2). Petitioners do not refute
    the FAA’s contention that the SCAQMD “thoroughly
    reviewed” and “correctly calculated” the FAA’s truck trips
    emissions analysis. As such, Petitioners provide no reason
    to believe that the EA did not correctly analyze total truck
    trips emissions.
    Finally, Petitioners argue that the record contains an
    inconsistency concerning the number of daily truck trips
    calculated by the FAA. Specifically, Petitioners point out
    that the FAA itself sometimes refers to the Project as
    38           CENTER FOR COMMUNITY ACTION V. FAA
    generating “3,823 daily truck trips” but uses a 192 daily
    truck trips figure to calculate air quality impact. Although
    Petitioners seem to suggest that the FAA impermissibly
    reduced the 3,823 figure to the 192 figure in calculating
    environmental impacts generally, the only portion of the EA
    that the FAA points to for the use of the 192 figure is the air
    quality impact calculation.
    Petitioners cite no portion of the EA that contains the
    3,823 figure but rather cite to portions of the FAA’s
    responses to public comments regarding the EA. This figure
    appears to come from the CEQA analysis, and was generated
    there to determine traffic volumes, pursuant to the City of
    San Bernardino’s requirement that truck trips be converted
    to “Passenger Car Equivalents” in determining traffic
    volumes. Under the City’s requirement, for every truck that
    possesses four or more axles, for example, one truck trip is
    equivalent to three passenger car trips and must be calculated
    as such.
    Petitioners, however, fail to articulate why the 3,823
    figure or the City’s conversion requirement is relevant for
    any environmental impact other than traffic volume.
    Petitioner’s argument that the FAA needed to explain why it
    relied on a 192 daily truck trips figure in determining air
    quality impact as opposed to the 3,823 figure assumes that
    the 3,823 figure is significant as it relates to air quality. But
    Petitioners fail to articulate what exactly that significance is.
    Moreover, Petitioners improvidently assume that the
    language “daily truck trips” after the two numbers designates
    both figures as describing the same calculation or statistic.
    Although the FAA could have been clearer about the
    differences between the 192 and 3,823 figures, it was
    Petitioners who assumed the two figures described the same
    calculation or statistic, and a review of where those figures
    CENTER FOR COMMUNITY ACTION V. FAA              39
    came from reveals their differing significances. Cf. Motor
    Vehicle Mfrs. Ass’n of U.S., Inc. v. State Farm Mut. Auto.
    Ins. Co., 
    463 U.S. 29
    , 43 (1983) (“We may not supply a
    reasoned basis for the agency’s action that the agency itself
    has not given. We will, however, uphold a decision of less
    than ideal clarity if the agency’s path may reasonably be
    discerned.” (citations and quotation marks omitted)). The
    FAA does not need to explain away the significance of a
    figure that Petitioners erroneously assume without
    explanation possesses certain significance or applies to
    environmental impacts apart from traffic volume.
    In sum, Petitioners fail to raise any legitimate concerns
    about the EA’s truck trips emissions calculations.
    F. California and Federal Environmental Standards
    Petitioners finally assert that the FAA failed to consider
    the Project’s ability to meet California state air quality and
    federal ozone standards. Petitioners’ arguments here invoke
    
    40 C.F.R. § 1508.27
    (b)(10)’s instruction that evaluating
    whether a project will have a “significant” environmental
    impact “requires consideration[] of . . . [w]hether the action
    threatens a violation of Federal, State, or local law or
    requirements imposed for the protection of the
    environment.”
    First, the CCA argues that the EA failed to assess
    whether the Project meets the air quality standards set by the
    California Clean Air Act (CCAA). The CCA’s contention
    in this regard is unavailing, however, because the CCA fails
    to identify even one potential CCAA violation stemming
    from the Project. This failure to specifically articulate a
    potential violation is what distinguishes this case from Sierra
    Club v. United States Forest Serv., 
    843 F.2d 1190
     (9th Cir.
    1988). In that case, the petitioner identified a specific
    40          CENTER FOR COMMUNITY ACTION V. FAA
    California water quality standard that one of its expert
    witnesses believed would be violated, and the expert witness
    explained how that violation would occur. 
    Id. at 1195, n.3
    .
    The only semblance of an attempt to articulate such a
    violation comes from the CCA’s citation in its reply brief to
    the CEQA analysis, which concluded that “[e]xceedances of
    applicable SCAQMD regional thresholds are considered
    significant and unavoidable[,]” and that “[t]he Project has
    the potential to result in or cause . . . CAAQS violations[.]”
    But, as previously discussed, the CEQA analysis’s
    conclusion in this regard is unavailing because of the
    SCAQMD’s letter refuting that contention in noting that the
    Project “will conform to the AQMP[.]”
    More importantly, the EA did discuss California air
    quality law. As explained in the EA, “[t]he [CCAA],
    administered by [the California Air Resources Board],
    requires all air districts in the state to achieve and maintain
    the California Ambient Air Quality Standards (CAAQS)[.]
    California law does not require that CAAQS be met by
    specified dates as is the case with NAAQS. Rather, it
    requires incremental progress toward attainment.” The
    implication here is that the FAA perceives no violation of
    the CCAA because the Project will be able to meet the
    incremental progress it needs for attainment. The CCA does
    not refute this contention. There is therefore no reason to
    believe that a CCAA violation is likely to occur and no
    reason to believe that the EA failed to consider whether the
    Project threatens a violation of the CCAA.
    Second, the CCA argues that the EA failed to assess
    whether the Project meets federal ozone standards. In 1979,
    the EPA adopted a national air quality standard, colloquially
    known as the “1-hour ozone standard,” limiting maximum
    1-hour average concentrations of ozone to 0.12 parts per
    CENTER FOR COMMUNITY ACTION V. FAA            41
    million. See 
    44 Fed. Reg. 8,202
     (Feb. 8, 1979) (codified at
    
    40 C.F.R. § 50.9
    ). Recognizing that further public health
    protection was needed, the EPA also adopted an “8-hour
    ozone standard” that similarly limits average concentrations
    of ozone. See 
    62 Fed. Reg. 38,856
     (July 18, 1997). The EPA
    has updated its 8-hour ozone standard twice, once in 2008,
    see 
    73 Fed. Reg. 16,436
     (Mar. 27, 2008), and once in 2015,
    see 
    80 Fed. Reg. 65,292
     (Oct. 26, 2015).
    The CCA argues that the EA fails to address the Project’s
    compliance with the 2008 and 2015 federal 8-hour ozone
    standard. The EA, however, states as follows:
    [O]perational emissions in 2019 would
    exceed the applicable de minimis thresholds
    for VOC and NOx resulting in a potential
    exceedance of the ozone and NO2 NAAQS.
    Thus, a [General Conformity Determination]
    is required for the Proposed Project’s
    emissions      of    non-attainment    and
    maintenance pollutants. The SCAQMD has
    confirmed the emissions of VOCs and NOx
    resulting from the Proposed Project are
    within the 2012 AQMP General Conformity
    Budget. The SCAQMD confirmation, in the
    form of a letter dated April 30, 2019, is
    provided in Attachment 2 of Appendix B.
    The letter stated that the proposed Project
    will conform to the AQMP (i.e., project
    emissions are within AQMP budgets) and is
    not expected to result in any new or
    additional violations of the NAAQS or
    impede the projected attainment of the
    standards.     The confirmation that the
    42          CENTER FOR COMMUNITY ACTION V. FAA
    estimated emissions are within the 2012
    AQMP General Conformity Budget
    demonstrates the Proposed Project will not
    jeopardize the timely attainment of the ozone
    NAAQS.
    The CCA recognizes that the letter relied upon by the EA
    “establishes the Project’s attainment of the 1997 ozone
    standard,” but it believes that the letter does not recognize
    such attainment of the 2008 and 2015 standards. Located
    within the letter, however, is a link to the “latest approved
    AQMP [which] is currently the Final 2012 AQMP[.]”
    Following the link reveals the Final 2012 AQMP, and
    Appendix IV(B): Proposed 8-hour Ozone Measures to the
    plan, which establishes how the Basin will attain the 2008 8-
    hour ozone standard. See 
    73 Fed. Reg. 16,436
     (Mar. 27,
    2008) (noting that EPA “for O3[ is] setting an AQI value of
    100 equal to 0.075 ppm, 8-hour average”); Appendix IV(B):
    Proposed 8-hour Ozone Measures Draft at Introduction and
    n.1 (setting out path to attain “75 ppb NAAQS” standard
    which the Draft notes was “adopted in 2008[ and] has been
    established by the U.S. EPA”). So, contrary to what the
    CCA asserts, the 2012 Final AQMP did “set[] a path to
    attainment of the [2008] federal ozone standard,” and the
    SCAQMD letter, relied upon by the EA, therefore
    establishes the Project’s attainment of the 2008 federal
    ozone standards by confirming the Project’s compliance
    with the 2012 AQMP.
    As for the 2015 federal ozone standard, the letter also
    addresses how the Project can meet that standard. The CCA
    itself recognizes that federal ozone standards can be met by
    ensuring that project emissions fall within the SCAQMD’s
    emissions “budget”:
    CENTER FOR COMMUNITY ACTION V. FAA            43
    [W]hen it became apparent that [the
    project’s] impacts on air quality would
    exceed de minimis thresholds for [federal
    ozone standards], the Airport looked for a
    loophole. On April 4, 2019, the Airport
    Authority requested that the Air District stash
    these emissions under its general conformity
    emissions budget for the 2012 Air Quality
    Management Plan. The Air District agreed. .
    . . [I]n order to accommodate this request, the
    Air District had to allocate almost half of its
    statewide emissions budget for the next five
    years to cover emissions from this specific
    project . . . .
    As the CCA recognizes, the SCAQMD can ensure emissions
    conform to federal ozone standards by allocating a certain
    amount of its “emissions budget” to a project. The
    SCAQMD letter recognizes this, as well:
    [I]n order to incorporate the projected aircraft
    operations in the next AQMP, South Coast
    AQMD staff recommends that detailed
    aircraft activity and emissions data for the
    San Bernardino International Airport be
    submitted to South Coast AQMD by the end
    of 2019. This way, these emissions can be
    appropriately included in the next AQMP
    emissions inventory and not rely on the
    general conformity budgets, which are in
    high demand and have a limited availability.
    Because the CCA does not demonstrate a risk of a violation
    of federal ozone standards and rather argues only that the EA
    44           CENTER FOR COMMUNITY ACTION V. FAA
    needed to determine whether a risk existed, the CCA does
    not refute the fact that the Project could be allocated a greater
    portion of the emissions budget, as the CCA admits
    happened before. In sum, the CCA provides no reason to
    believe that the Project threatens a violation of the federal
    ozone standards. Cf. Am. Wild Horse Campaign, 963 F.3d
    at 1009.
    Finally, Petitioners argue that the EA failed to assess
    whether the Project meets California’s greenhouse gas
    emission standards. Petitioners, however, only cite to
    California statutory pronouncements that statewide
    greenhouse gas emissions must be reduced to certain levels
    by certain time periods. Those statutes charge the California
    Air Resources Board with determining exactly how to
    accomplish that task. See 
    Cal. Health & Safety Code §§ 38501
    , 38550, 38561, 38566. In its brief, California points
    to the CEQA analysis’s finding of a significant
    environmental impact resulting from the Project’s
    greenhouse gas emissions. In conflict with Petitioners’
    assertion, however, the CEQA analysis itself finds that “[t]he
    Project would not conflict with any applicable plan, policy,
    or regulation of an agency adopted for the purpose of
    reducing the emissions of greenhouse gases.” The CEQA
    analysis goes on to state:
    [The California Air Resources Board]’s
    Scoping Plan identifies strategies to reduce
    California’s greenhouse gas emissions in
    support of AB32 which requires the State to
    reduce its GHG emissions to 1990 levels by
    2020. Many of the strategies identified in the
    Scoping Plan are not applicable at the project
    level, such as long-term technological
    CENTER FOR COMMUNITY ACTION V. FAA           45
    improvements to reduce emissions from
    vehicles. Some measures are applicable and
    supported by the project, such as energy
    efficiency. Finally, while some measures are
    not directly applicable, the Project would not
    conflict with their implementation.
    . . . As summarized, the project will not
    conflict with any of the provisions of the
    Scoping Plan and in fact supports seven of the
    action categories through energy efficiency,
    water     conservation,     recycling,    and
    landscaping.
    . . . Executive Order[] S-3-05 . . . [is an]
    order[] from the State’s Executive Branch for
    the purpose of reducing GHG emissions. The
    goal of Executive Order S-3-05 is to reduce
    GHG emissions to 1990 levels by 2020 [and]
    was codified by the Legislature as the 2006
    Global Warming Solutions Act (AB 32). The
    Project, as analyzed above, is consistent with
    AB 32. Therefore, the Project does not
    conflict with this component of Executive
    Order S-3-05. . . .
    As shown above, the Project would not
    conflict with any of the 2017 Scoping Plan
    elements as any regulations adopted would
    apply directly or indirectly to the Project.
    The CEQA analysis therefore recognizes that the Project will
    not risk a violation of the California sources of law that
    Petitioners argue the EA needed to consider. While the
    46          CENTER FOR COMMUNITY ACTION V. FAA
    CEQA analysis’s discussion of the Project’s compliance
    with state standards does not necessarily absolve the FAA of
    the duty to include such a discussion in the EA, it does
    suggest that there is no risk of such a violation. And
    although the CEQA analysis found that the emissions from
    the Project’s operational activities would exceed the
    SCAQMD threshold even with mitigation measures, as
    discussed earlier, Petitioners do not refute the EA’s other
    rationale for finding no significant environmental impact
    stemming from the Project’s greenhouse gas emissions. See
    Wild Wilderness, 871 F.3d at 727 (“One of these factors may
    demonstrate intensity sufficiently on its own, although the
    presence of one factor does not necessarily do so.” (citation
    omitted)).
    Because Petitioners have failed to proffer any specific
    articulation of how the Project will violate California and
    federal law, there is no reason to believe that the EA is
    deficient for purportedly failing to explicitly discuss the
    Project’s adherence to California and federal environmental
    law. See Sierra Club, 
    843 F.2d at 1195
     (ordering the
    preparation of an EIS, in part, because Petitioner articulated
    a specific way of how the “harvesting of the nine timber sales
    may violate California’s water quality standards”).
    III. Conclusion
    Petitioners have failed to establish that the FAA acted
    arbitrarily or capriciously in this case, so their Petition is
    DENIED.

    By making this statement, I in no way intend to cast any aspersions on
    my esteemed colleagues in the majority for not addressing this issue. I
    readily acknowledge that the primary focus of the parties was on the
    technical violations of the Environmental Assessment. However, I
    hasten to add that this observation was not plucked out of thin air. The
    State of California, both in its comments to the draft Environmental
    Assessment and in its brief to this court, pointed out the designation of
    the San Bernardino area as an environmental justice community
    populated primarily by people of color and already saturated with
    pollution. In response, the Environmental Assessment, under the
    Caption of “Socioeconomics [and] Environmental Justice,” without
    addressing the State’s expressed concerns, rendered the cursory
    conclusion that the Amazon Project “would not result in any significant
    socioeconomic impacts [or] environmental justice impacts.” This
    cursory conclusion did not come anywhere close to taking the “hard
    look” required by the National Environmental Policy Act (NEPA). Am.

    Environmental racism is real. As recently as 2018, a
    group of scientists for the federal Environmental Protection
    Agency (EPA) published a scholarly study of environmental
    racism. See Ihab Mikati BS, Adam F. Benson, MSPH,
    Thomas J. Luben, PhD, MSPH, Jason D. Sacks, MPH, and
    Jennifer Richmond-Bryant, PhD, Disparities in Distribution
    of Particulate Matter Emission Sources by Race and Poverty
    Status, Am. J. of Public Health (Envtl. Justice), Vol. 108, No.
    4 (2018). In explaining the basis for their study, the scholars
    acknowledged initially the existence of “[p]revious literature
    [showing] that non-Whites and below-poverty individuals
    are more likely to reside near” highly polluted sites. 
    Id. at 480
    . The scientists measured exposure to air pollution in
    view of the “human health impacts of residential proximity
    to facilities emitting air pollutants.”

     The scientists
    focused on the specific air pollutant of “particulate matter
    (PM), a mixture of solid and liquid particles suspended in the
    air.”

     They explained that exposure to PM 2.5 “has been
    [especially] associated with a number of health effects,
    including respiratory and cardiovascular diseases as well as
    premature mortality.” 2 
    Id.
    The EPA scientists examined facility emissions data and
    demographic data to reach their conclusion that “non-Whites
    . . . face a disproportionate burden from PM-emitting
    facilities. Blacks in particular are likely to live in high-
    emission areas . . .

    Almost twenty-five years ago, academics recognized the
    problem of environmental racism. See Environmental

    regulatory model for environmental justice . . . to stop the
    trend of allowing people of color to bear the brunt of living
    with” environmental pollution). Various studies confirmed
    that “[m]inority communities are bearing a greater
    proportion of the effects of past and current industrial
    pollution.” Id. at 318. This disproportion is no coincidence,
    despite efforts to characterize it as such. See id. at 320.
    Notably, “neglect of minority communities under
    environmental law occurs whether or not the communities
    are poor.” Id. at 335.
    One of the more heartbreaking instances of
    environmental racism was documented recently by the
    United Nations. Environmental racism in Louisiana’s
    ‘Cancer Alley’ must end, say UN human rights experts
    (March 2, 2021). https://news.un.org/en/story/2021/03/108
    6172. The UN branded this proliferation of pollution
    sources “environmental racism,” and noted that the pollution
    “subjected the mostly African American residents . . . to
    cancer, respiratory diseases and other health problems,”
    similar to those evidenced in heavily polluted San
    Bernardino County. Id. “According to data from the
    Environmental Protection Agency’s National Air Toxic
    Assessment map, the cancer risks in predominantly African
    American Districts . . . could be at 104 and 105 cases per
    million, while those threats in predominantly white districts
    50            CENTER FOR COMMUNITY ACTION V. FAA
    range from 60 to 75 per million. Id. Stated differently, the
    cancer risk for African Americans is almost twice that of
    white Americans, all because of unchecked pollution. Sadly,
    the experts concluded that “federal environmental
    regulations have failed to protect people residing in ‘Cancer
    Alley.’”
    Despite the designation of the South Coast Air Basin by
    the EPA as an “extreme” non-attainment area for ozone and
    “serious” non-attainment for PM2.5, 3 a finding one year
    earlier by the San Bernardino International Airport
    Authority that the project would have significant and
    unavoidable environmental impacts, and the release of one
    ton of additional air pollution a day into the already overly-
    polluted air of San Bernardino County, the Federal Aviation
    Administration (FAA) concluded that the project would
    have no significant impact on the environment. This
    conclusion would be laughable if the consequences were not
    so deadly to the population of San Bernardino County.
    Because of its conclusion of no significant impact, the FAA
    did not prepare an Environmental Impact Statement (EIS)
    assessing the effect of the project on the already-polluted
    San Bernardino community. I must dissent.
    With the definition of environmental racism firmly in
    mind, I turn to the summary of this case. The project at issue
    is a massive package distribution center for Amazon located
    at the San Bernardino International Airport (Airport). 4

    Although the FAA designated this project as the “Eastgate Air Cargo
    Facility,” I call it what it really is—the Amazon Project.
    CENTER FOR COMMUNITY ACTION V. FAA                  51
    of organizations and the State of California (collectively
    Petitioners). Petitioners specifically challenge the Finding
    of No Significant Impact (Impact) from the FAA.
    Petitioners maintain that the FAA violated the National
    Environmental Policy Act (NEPA) by not preparing an EIS
    analyzing the environmental effects of the Amazon Project
    on the surrounding San Bernardino community.
    Background
    The Amazon Project is an air cargo facility intended to
    “support large-scale air cargo operations with on-airport
    package sorting capabilities.” It will occupy 101.5 acres of
    the Airport, located on the former Norton Air Force Base.
    Notably, upon its closure Norton Air Force Base was
    designated a superfund site due to past hazardous waste
    management and onsite disposal practices. 5 Even before
    approval of the Amazon Project, the Airport already
    conducted activities involving the use of hazardous
    materials, including fueling of aircraft and vehicles, and the
    use of oils, antifreeze, paints, sealants, foam, and liquid-
    extinguishing compounds.
    The Amazon Project will add to this mix of pollutants
    taxiways and a parking apron for fourteen aircraft; a 658,500
    square-foot building for offices, package sorting, and
    distribution; two 25,000 square-foot maintenance buildings;
    and roughly 2,000 parking spaces. According to the FAA’s
    Environmental Assessment, the Amazon Project will

    The Federal Superfund Program was established by the EPA pursuant
    to the Comprehensive Environmental Response, Compensation, and
    Liability Act of 1980. The program developed a list of sites
    contaminated with hazardous substances, pollutants, or contaminants.
    As noted, Norton Air Force Base was added to the Superfund Program
    due to widespread contamination at that location.
    52          CENTER FOR COMMUNITY ACTION V. FAA
    generate 24 daily take-offs and landings at the airport, 192
    daily roundtrip truck trips, and 3,486 daily passenger-car
    trips in its first year of operation. By the year 2024, daily
    take-offs and landings will increase to 26, daily roundtrip
    truck trips to 500, and daily passenger-car trips to 7,516.
    One year before the FAA issued its finding of no
    significant impact, the State of California evaluated the
    environmental impact of the Amazon Project under the
    California Environmental Quality Act (CEQA), the state
    corollary to NEPA. The State of California’s final
    Environmental Impact Report concluded that operation of
    the Amazon Project would result in “significant impacts” on
    air quality, greenhouse gases, and noise.
    It is difficult to square the State of California’s
    conclusion of significant impacts with the FAA’s conclusion
    of no significant impact. Petitioners contend that the
    difference can be explained by the failure of the FAA to take
    the requisite “hard look” at the Amazon Project as required
    by NEPA. I agree with the Petitioners.
    Discussion
    When reviewing the FAA’s decision not to prepare an
    EIS, we are tasked with determining whether the agency
    took a “hard look” at the environmental effects of the
    proposed project. Am. Wild Horse Campaign v. Bernhardt,
    
    963 F.3d 1001
    , 1007 (9th Cir. 2020). The FAA was also
    required to “provide[] a convincing statement of reasons to
    explain why a project’s impacts are insignificant.” 
    Id.
    (citation omitted). On this record, I am not convinced that
    the FAA has done so. In my view, Petitioners “rais[ed]
    substantial questions whether a project may have a
    significant effect,” thereby requiring preparation of an EIS.

    , 1136 (9th
    Cir. 2011) (citation omitted).
    1. The General Study Area
    Petitioners contend that the General Study Area for the
    Amazon Project was defined too narrowly to capture the
    totality of the impacts on air quality, vehicle traffic,
    socioeconomic issues, and other land uses. The FAA
    counters that the General Study Area was drawn
    appropriately. Both parties anchor their arguments to the
    FAA’s 1050.1F Desk Reference. 6
    The FAA specifically maintains that the General Study
    Area was drawn in compliance with Appendix B of its Desk
    Reference and that, in any event, the Desk Reference is not
    binding. However, the FAA’s reliance on Appendix B does
    not support its decision to define the General Study Area to
    include only:
    roughly the region around the Airport within
    the 2024 Proposed Project community noise
    equivalent level (CNEL) 65 decibels (dB)
    and higher aircraft noise contours, the Airport
    property, and the neighborhoods north of the
    Airport through which employee vehicle and
    truck traffic is expected to flow to and from
    the Proposed Project site (roughly between
    Tippecanoe Avenue, Highway 210, and
    Victoria Avenue).
    6
    The FAA’s waiver argument is not well-taken. Petitioners sufficiently
    addressed the “arbitrarily narrow General Study Area” in its comments
    to the draft Environmental Assessment.
    54          CENTER FOR COMMUNITY ACTION V. FAA
    This study area “includes parts of the cities of San
    Bernardino, Highland, and Redlands, as well as areas of
    unincorporated San Bernardino County.” The total distance
    is approximately 11 square miles.
    According to the Environmental Assessment, the
    General Study Area is meant “to assess direct and indirect
    impacts of the Proposed Project,” which echoed the
    definitions in the Council on Environmental Quality (CEQ)
    regulations implementing the version of NEPA then in
    effect. See 
    40 C.F.R. § 1508.8
    (a)-(b) (2019) (defining
    “effects” as “[d]irect” and “[i]ndirect”).
    The FAA asserts that the General Study Area is large
    enough to evaluate the effects on all environmental impact
    categories because it was drawn in accordance with
    Appendix B of FAA Order 1050.1F. But Appendix B
    provides that “[t]he compatibility of existing and planned
    land uses with proposed aviation actions is usually
    determined in relation to the level of aircraft noise.”
    (emphasis added). Appendix B does not support a
    conclusion that a study area linked solely to the level of
    aircraft noise is adequate to analyze every environmental
    impact. In fact, the desk reference reflects the opposite
    approach: “The study area varies based on the impact
    category being analyzed.”
    According to the Desk Reference, “[t]he study area for
    air quality should be defined as the entire geographic area
    that could be either directly or indirectly affected by the
    proposed project.” Indeed, the Desk Reference notes that a
    project “can lead to air pollutant emissions that may occur at
    some distance from a project site, such as exhaust from
    project-generated vehicle traffic on the surrounding road
    network,” so “the study area for a project’s air quality
    CENTER FOR COMMUNITY ACTION V. FAA            55
    analysis could encompass many square miles and/or
    multiple air basins.”
    The Amazon Project is not simply an aviation activity
    that will increase aircraft noise, but a massive distribution
    hub that will also produce significant mobile emissions,
    particularly from trucks. According to the Environmental
    Assessment, the Amazon Project may generate one-way
    trips by heavy trucks that will extend well beyond the
    General Study Area: from 26.9 miles (to Cajon Pass) to
    80.47 miles (to Los Angeles/Long Beach), with the average
    trip being 64.25 miles. Thus, the effects of the Amazon
    Project extend well beyond the 11-mile General Study Area.
    The FAA glosses over its deficient designation of the
    General Study Area by stating that it “considered the
    potential air quality impacts of vehicle traffic flowing
    between the Project and locations outside the boundary of
    the General Study Area.”           But the section of the
    Environmental Assessment that the FAA references simply
    mentions those trips. Tellingly, the FAA does not point to
    any analysis regarding those trips. Indeed, the FAA took the
    position in its brief that the 11-square-mile General Study
    Area is large enough to address all environmental impacts,
    and the Environmental Assessment echoes that view.
    The Environmental Assessment is similarly deficient in
    its analysis of socioeconomic impacts. The Desk Reference
    instructs that “[f]or socioeconomics, the study area may be
    larger than the study area for other impact categories and
    should consider the impacts of the alternatives on the
    following broad indicators: economic activity, employment,
    income, population, housing, public services, and social
    conditions.” “The baseline conditions should include the
    size of local population centers, the distance from a project
    56          CENTER FOR COMMUNITY ACTION V. FAA
    site to these areas, and the nature of the local economics.”
    
    Id.
    Petitioners point out, and the FAA does not dispute, that
    “the General Study Area is significantly smaller than the
    local population centers for the Cities of San Bernardino,
    Highland, Redlands, and unincorporated San Bernardino
    County, even though [the Amazon Project] is located in or
    borders each of these areas.” Indeed, the FAA confirms that
    it only assessed socioeconomic impacts for “areas located
    within the aircraft noise contours” and “neighborhoods north
    of the Airport through which employee vehicle and truck
    traffic is expected to flow to and from the Project site.” But
    economic activity, employment, and other broad
    socioeconomic factors do not travel only as far as noise and
    trucks traffic.
    In sum, the General Study Area does not encompass all
    of the Amazon Project’s potential direct and indirect effects
    on air quality and socioeconomic conditions. Consequently,
    the FAA failed to take the requisite “hard look” at these
    consequences of the project. Am. Wild Horse Campaign,
    963 F.3d at 1007.
    2. Cumulative Impacts Analysis
    In addition to the FAA’s failure to designate a
    sufficiently extensive General Study Area, the Petitioners
    submit that the FAA’s cumulative impacts analysis was also
    deficient because it ignored more than 80 projects located
    immediately outside the study areas, and the Environmental
    Assessment failed to “disclose specific, quantifiable data
    about the cumulative effects of related projects,” “explain
    why objective data about the projects could not be
    provided,” or “discuss the combined effects of these
    projects.”
    CENTER FOR COMMUNITY ACTION V. FAA              57
    The FAA responds that (1) it considered the 80 projects
    outside the General Study Area, albeit only for cumulative
    traffic impact and not for overall cumulative impacts; (2) it
    was only required to include within the cumulative impacts
    analysis 26 projects located within the General Study Area,
    which it did; and (3) the cumulative impacts analysis may
    consist of detailed information rather than quantified data, as
    provided in a chart describing the 26 projects within the
    General Study Area, along with an explanation of the
    cumulative impact of these projects.
    “Cumulative impact is the impact on the environment
    which results from the incremental impact of the action
    when added to other past, present, and reasonably
    foreseeable future actions . . .” 
    40 C.F.R. § 1508.7
     (2019).
    “[A]n agency must provide some quantified or detailed
    information” regarding cumulative impacts. Bark v. United
    States Forest Serv., 
    958 F.3d 865
    , 872 (9th Cir. 2020)
    (internal quotation marks omitted). “General statements
    about possible effects and some risk do not constitute a hard
    look absent a justification regarding why more definitive
    information could not be provided.” 
    Id.
     (citation, alteration,
    and internal quotation marks omitted). Moreover, the
    analysis “must be more than perfunctory; it must provide a
    useful analysis of the cumulative impacts of past, present and
    future projects.” 
    Id.
     (citation omitted).
    Preliminarily, given my conclusion that the General
    Study Area is not large enough to adequately analyze the
    Amazon Project’s effects on air quality and socioeconomics,
    it necessarily follows that the cumulative effects analysis is
    similarly flawed.
    The FAA’s cumulative effects analysis is also
    inadequate for three other reasons. First, the FAA does not
    58          CENTER FOR COMMUNITY ACTION V. FAA
    explain why it analyzed the delineated 80 projects for traffic
    effects only, and no rationale was provided for limiting the
    analysis. If the projects would affect traffic, they would
    logically also affect air quality, and likely other
    environmental areas.
    Second, the Environmental Assessment includes a table
    of only 26 past, present, and future projects with minimal
    information: a description of the project, the address, the
    timeframe/status, and potential resources affected. This
    Court has rejected similar tables that contain little to no
    information. See Bark, 958 F.3d at 872 (criticizing table that
    “gave no information about any of the projects listed” but
    “merely named them”); see also Klamath-Siskiyou
    Wildlands Ctr. v. BLM, 
    387 F.3d 989
    , 994 (9th Cir. 2004)
    (same, for table that did not provide “objective
    quantification of the impacts” and “informed only that a
    particular environmental factor will be ‘unchanged,’
    ‘improved,’ or ‘degraded’ and whether that change will be
    ‘minor’ or ‘major’”). Giving basic information about other
    projects may be a good start toward analyzing their
    collective effect on the environment, but it is not enough.
    See Klamath-Siskiyou, 387 F.3d at 995.
    Third, explanation of the cumulative effects in the
    Environmental Assessment is similarly inadequate. For
    instance, the Environmental Assessment states that
    “cumulative projects have a moderate to low potential to
    result in permanent, significant cumulative air quality
    impacts,” without any quantification of the emissions from
    these projects, individually or collectively. The same holds
    true for the analysis of roadway noise. The Environmental
    Assessment states that “to noticeably increase noise (i.e., an
    increase of 3 dB), vehicle traffic volume would need to
    double,” and “[c]onsidering the nature of the cumulative
    CENTER FOR COMMUNITY ACTION V. FAA              59
    projects, a doubling of traffic volumes would not be
    expected and cumulative impacts associated with roadway
    noise would not be anticipated.” But the Environmental
    Assessment does not expand upon that conclusion. Nor does
    it quantify anticipated traffic or generated noise levels.
    The FAA concedes that it did not quantify its
    conclusions, but argues that its detailed explanations are
    sufficient. However, that argument runs afoul of our
    decision in Klamath-Siskiyou, 387 F.3d at 994 (rejecting
    cumulative effects conclusion that contained “no quantified
    assessment of [the projects’] combined environmental
    impacts” and a table that did not inform “what data the
    conclusion was based on, or why objective data cannot be
    provided”). In sum, the FAA offers “the kind of conclusory
    statements, based on vague and uncertain analysis, that are
    insufficient to satisfy NEPA’s requirements.” Bark, 958
    F.3d at 872 (internal quotation marks omitted).
    3. Number of Daily Truck Trips
    Petitioners point out that the FAA reduced estimated
    daily truck trips in the Environmental Assessment by 95%
    without explanation.        Although the Environmental
    Assessment states that the Amazon Project will generate 192
    daily truck trips in 2019, a NEPA Data Spreadsheet
    incorporated into the Environmental Assessment and one of
    the FAA’s responses to comments reference a much higher
    number: 3,823 daily truck trips.
    The State of California raises a similar argument based
    on California’s Environmental Impact Report for the
    Amazon Project, reflecting 248 daily truck trips the first year
    and 652 daily truck trips at full operation. California also
    notes that the Environmental Assessment models only half
    of mobile emissions because the modeling program used by
    60            CENTER FOR COMMUNITY ACTION V. FAA
    the FAA only counts one-way trips. These miscalculations
    underestimated potential emissions, thereby failing to
    account for the project’s true intensity and context.
    The FAA counters that its methodology is reasonable.
    While acknowledging that California’s report estimated
    more truck trips, the FAA notes that the California report
    “predated the final Environmental Assessment by more than
    a year,” 7 and that estimates of how many packages the
    Amazon Project would process daily decreased from that
    time. The FAA then speculates that “the decrease in package
    volumes may explain the decrease in truck trips between the
    [California] Report and the Environmental Assessment,”
    even though the record does not reflect that California’s
    calculation was predicated on package volumes.
    The FAA disputes California’s statement that the
    Environmental Assessment only modeled emissions for one-
    way truck trips.         The FAA emphasizes that the
    Environmental Assessment continuously states that all truck
    trips are “round trips.” The FAA also relies on its response
    to comments that “[u]pon completion of the [modeling
    program], further analysis was completed to calculate the
    total round trip truck traffic emissions that would be
    generated by the operation of the Proposed Project.”
    However, the FAA does not identify this “further analysis.”
    Regarding the reference to “3,823 daily truck trips,” the
    FAA first argues that the figure concerns traffic analysis
    7
    Although the California environmental report was finalized on October
    1, 2018, the trip calculations are based on a Traffic Impact Analysis
    performed on July 2, 2018. The calculations for the NEPA analysis were
    done on January 15, 2019. So the time between the calculations is not
    “more than a year,” but approximately six months.
    CENTER FOR COMMUNITY ACTION V. FAA              61
    only and that its “assessment of traffic impacts is not an issue
    in this case.” The FAA then contends that the figure’s
    inclusion in an Environmental Assessment appendix and a
    spreadsheet were “minor” and “inconsequential” errors. The
    FAA reasons that it converted truck trips to “passenger car
    equivalents (PCE),” but acknowledges that it also “stated
    incorrect numbers that were larger than the PCE conversion
    would yield” and also “inadvertently omitted the PCE
    abbreviation and said ‘daily truck trips.’” So rather than
    referencing 3,823 daily truck trips, the documents should
    have referenced 1,738 PCE. However, the record does not
    support this explanation. The FAA stated in its responses to
    comments that, according to the traffic analysis, the Amazon
    Project would generate “3,826 daily passenger car trips” and
    “also include approximately 3,823 daily truck trips.” “Truck
    trips were converted to PCE using the City’s conversion
    rates of 2.0 for 2-axle trucks, 2.5 for 3-axle trucks and 3.0
    for 4+ axle trucks,” resulting in “8,007 daily PCE trips,”
    which is roughly 2.09 times 3,823. A PCE of 8,007 would
    be consistent with 3,823 daily trips by mostly 2-axle trucks
    and a few 3-axle trucks. In short, the 3,823 figure cannot be
    dismissed as a typo.
    In sum, the FAA did not give the requisite “hard look”
    to potential truck emissions because it arbitrarily used two
    different truck-trip figures and did not provide the “further
    analysis” of roundtrip emissions. Importantly, the FAA
    concedes that “none of FAA’s air emissions calculations
    [were] based on the traffic figures.” This failure to link air
    emissions calculations to traffic figures reflects a “fail[ure]
    to consider an important aspect” of the Amazon Project, a
    violation of NEPA. Motor Vehicle Mfrs. Assn. of U.S. v.

    No logical reason exists to divorce traffic figures from
    emission calculations. Emissions are generated from mobile
    sources, like trucks. If the FAA did not account for most
    mobile sources when it calculated emissions, it failed to
    provide “a convincing statement of reasons to explain [the
    Amazon Project’s] impacts are insignificant.” Am. Wild
    Horse, 963 F.3d at 1007. The FAA’s post hoc explanations
    do not satisfy its obligations under NEPA. 8 See Dep’t of
    Homeland Sec. v. Regents of the Univ. of California, 
    140 S. Ct. 1891
    , 1909 (2020) (“An agency must defend its actions
    based on the reasons it gave when it acted. . . .”).
    Conclusion
    The FAA’s conclusion that the emissions-spewing
    Amazon Project will have no significant environmental
    impact on the already overly-polluted San Bernardino
    Valley does not pass muster under NEPA.               The
    Environmental Assessment does not come close to taking the
    requisite “hard look” at the environmental consequences of
    this massive project.       Let me count the ways the
    Environmental Assessment is deficient:
    1.      Failing To Define The General Study Area In
    A Sufficiently Broad Manner So As To
    Capture The Totality Of The Environmental
    Impact.

    A persuasive argument was also made regarding the FAA’s failure to
    address air quality standards. However, in view of the significant
    deficiencies already discussed, I will not delve further into that issue.

    2.      Failing To Include More Than 80 Projects
    Located Immediately Outside The Study
    Areas In The Cumulative Impacts Analysis.
    3.      Patently Undercounting The Number Of
    Daily Truck Trips In Calculating Potential
    Truck Omissions.
    4.      Ignoring The Analysis Conducted By The
    State of California Concluding That The
    Amazon Project Would Result In
    “Significant      And        Unavoidable”
    Environmental Impacts To The Already
    Over-Polluted San Bernardino Valley.
    5.      Ignoring The Designation Of The San
    Bernardino Valley By The EPA As An
    “Extreme” Non-Attainment Area For
    Particulate Matter.
    Does anyone doubt that this Environmental Analysis
    would not see the light of day if this project were sited
    anywhere near the wealthy enclave where the
    multibillionaire owner of Amazon resides? Certainly not.
    The same standard should apply to the residents of San
    Bernardino Valley, who have already borne for many years
    the heavy cost of pollution resulting in a quantifiable
    detriment to their health. But such is the nature of
    environmental racism. See Environmental Racism, 6 Tul.

    Residents of the San Bernardino Valley are not
    disposable. Their lives matter. A recent article in the
    Washington Post is a startling reminder of the pall pollution
    has cast over the planet. According to a scientist from the
    64           CENTER FOR COMMUNITY ACTION V. FAA
    Grantham Institute for Climate Change and the
    Environment, “[i]t is likely that nearly everyone in the world
    now experiences changes in extreme weather as a result of
    human greenhouse gas emissions.” Annabelle Timsit and
    Sarah Kaplan, At least 85 percent of the world’s population
    has been affected by human-induced climate change, new
    study shows, The Washington Post, October 11, 2021.
    Closer to home, over the summer “hundreds of people in the
    Pacific Northwest died after unprecedented heat baked the
    unusually temperate region.” Id.; see also Doyle Rice, Over
    4 of 10 Americans breathe polluted air report says. And
    people of color are 61% more likely to be affected, USA
    Today, April 21, 2021 (citing a report from the American
    Lung Association). Our children and grandchildren are
    looking to us to stem this tide of pollution that is contributing
    to increasingly disastrous climate change. See Climate
    Change, https://world101.cfr.org/global-era-issues/climate-
    change (last visited Oct. 20, 2021). This emissions-spewing
    facility that disproportionately impacts communities of color
    and was not properly vetted is a good place to start.
    We must do better, and I must dissent.
