    SUMMARY **
    Environmental Law
    The panel vacated the district court’s summary judgment
    in favor of the U.S. Forest Service, and the Forest Service’s
    Decision Memo approving the proposed Tecuya Ridge
    Shaded Fuelbreak Project; and remanded to the Forest
    Service to provide adequate substantiation for its
    determination that 21-inch dbh (diameter at breast height)
    trees are generally small diameter timber within the Project
    Area.
    Tecuya Ridge is located within the Los Padres National
    Forest, and is home to densely populated forest stands that
    the Forest Service determined to be at risk of destruction by
    wildfire. The Tecuya Ridge Project authorized thinning
    1,626 acres of forest, including approximately 1,100 acres
    within a protected area called the Antimony Inventoried
    Roadless Area (“IRA”). The Roadless Area Conservation
    Rule was established in 2001 pursuant to a presidential

    directive to initiate a nationwide plan to protect inventoried
    and uninventoried roadless areas within national forests.
    Generally, timber cutting, sale or removal in areas like the
    Antimony IRA are prohibited by the Roadless Area
    Conservation Rule. The Rule provides for some exceptions.
    The panel held that the Forest Service’s conclusion that
    the Tecuya Ridge Project was consistent with the Roadless
    Area Conservation Rule was arbitrary and capricious. The
    panel held that the Forest Service’s determination that 21-
    inch dbh trees were “generally small timber” was arbitrary
    and capricious. The panel found no record evidence to
    support this determination. In addition, the Forest Service
    failed to articulate a satisfactory explanation – in the
    administrative record, in briefing, and at oral argument – for
    its determination that the 21-inch dbh trees in the Project
    area were “generally small” within the meaning of the
    Roadless Rule. Because the panel could not discern how the
    Forest Service arrived at the 21-inch dbh number, the panel
    remanded for the Forest Service to substantiate its
    conclusion that 21-inch dbh trees are “generally small”
    within the project area, consistent with the Roadless Rule.
    The panel held that the Forest Service’s determination
    that the Project will “maintain or improve” the Antimony
    Roadless Area’s characteristics was not arbitrary and
    capricious. The Forest Service met its obligations under
    Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto Ins. Co.,
    
    463 U.S. 29
    , 43 (1983), to articulate a satisfactory
    explanation for its action.
    The panel held that the Forest Service’s decision to
    “categorically exclude” the Tecuya Ridge Project from
    review in an environmental assessment or environmental
    impact statement, pursuant to the National Environmental
    4          LOS PADRES FORESTWATCH V. USFS
    Policy Act (“NEPA”), was not arbitrary and capricious.
    First, the Forest Service’s determination that Categorical
    Exclusion 6 (“CE-6”) applied to the Project was not arbitrary
    and capricious. Second, the Forest Service’s determination
    that no extraordinary circumstances prevented its
    application of CE-6 to the Project was not arbitrary and
    capricious. Consistent with 
    36 C.F.R. § 220.6
    , the Forest
    Service analyzed each resource condition – that should be
    considered in determining whether there were extraordinary
    circumstances related to the proposed action – and
    determined that the Project would have “no significant
    impact” on each. In addition, the Forest Service’s decision
    to locate the Project in the “wildland zone” instead of the
    “threat zone” was not arbitrary and capricious because the
    Forest Service substantiated its decision with evidence in the
    record.
    Judge R. Nelson dissented. He agreed with Sections I.B
    and II of the majority opinion. He wrote, however, that the
    majority wrongly held that the Forest Service’s
    determination that 21-inch dbh trees are “small diameter”
    was arbitrary or capricious under the Administrative
    Procedure Act. He would deny the petition for review.

    OPINION
    STEIN, District Judge:
    The Tecuya Ridge, part of the San Emigdio Mountain
    range, rises up from the Los Padres National Forest and
    overlooks the mountain communities of Lebec, Frazier Park,
    Lake of the Woods, Pine Mountain Club, and Pinon Pines
    Estates. The Ridge falls within the Mt. Pinos Place
    Management Area, an environment forested with old-growth
    trees, including Singleleaf pinyon-California juniper and
    Montane conifer. The area provides habitat for the
    California condor, the California spotted owl, and the
    northern goshawk and affords a scenic backdrop to the
    mountain communities nestled within it. But because the
    Tecuya Ridge is home to densely populated forest stands, 1
    the Forest Service has determined that both the forest and the
    adjacent mountain communities are at risk of destruction by
    wildfire. To address this risk, the Forest Service proposed
    the Tecuya Ridge Shaded Fuelbreak Project (the “Project”)
    in March 2018. The Project aims to create a fuelbreak, a
    “wide strip or block of land on which the native or pre-
    existing vegetation has been permanently modified so that
    fires burning into it can be more readily extinguished,” 2
    running roughly in a jagged line along the Tecuya Ridge.
    1
    A “stand” is a “contiguous group of trees sufficiently uniform in
    age class distribution, composition, and structure, and growing on a site
    of sufficiently uniform quality, to be a distinguishable unit.”

    In April 2019, Los Padres Forest Supervisor Kevin Elliot
    published a Decision Memo approving the Project.
    Appellants Los Padres ForestWatch, Center for Biological
    Diversity, and Earth Island Institute filed a complaint
    challenging this decision on two grounds: that the Forest
    Service’s approval of the project violates the National
    Environmental Policy Act of 1969 (“NEPA”), and that the
    Project authorizes logging large diameter trees in violation
    of the Roadless Area Conservation Rule. The parties filed
    cross-motions for summary judgment. The district court
    granted Appellee’s motion for summary judgment and
    denied Appellants’ motion for summary judgment.
    Appellants filed a timely notice of appeal on August 20,
    2020.
    Because the Forest Service has failed to explain how its
    decision to approve the Project complies with the
    requirements of the Roadless Area Conservation Rule, the
    Court vacates the district court’s decision and the Forest
    Service’s Decision Memo approving the Project and
    remands this case to the Forest Service to substantiate its
    conclusions.
    BACKGROUND
    Since 1998, fifteen wildfires have burned through the
    Tecuya Ridge. The Forest Service believes that the risk of
    wildfire in that area remains high because the Tecuya Ridge
    consists of densely packed forest stands. Overcrowded
    stands are vulnerable to severe wildfire because they are full
    of tightly packed forest fuels—combustible forest
    materials—like shrubs, brush, and tree branches. 3 “Surface”

    Structure on Wildfire Behavior and the Severity of Its Effects 1 (2003).

    fuels lie on the forest floor, while “ladder” fuels allow
    wildfire to climb from the forest floor to the tree canopies. 4
    The Forest Service has determined that surface and ladder
    fuel loads, dense tree crown cover, continued periods of
    drought, and the presence of trees ravaged by insects and
    disease in the Tecuya Ridge pose a risk of a wildfire with the
    potential to destroy an entire forest stand.
    Accordingly, the Forest Service proposed the Tecuya
    Ridge Shaded Fuelbreak Project in March 2018. The Project
    Decision Memo explains that the Project aims to create a
    fuelbreak to “provide safe and effective locations from
    which to perform fire suppression operations,” to “slow the
    spread of wildland fire,” to “reduce the potential for the loss
    of life, property, and natural resources,” and to “increase the
    forest’s resilience to insects and diseases.”
    To accomplish these goals, the Project authorizes
    thinning 1,626 acres of forest, including approximately
    1,100 acres within a protected area called the Antimony
    Inventoried Roadless Area (“IRA”).          “Thinning,” as
    explained in the Project Decision Memo, means that
    commercially viable trees will be cut down and
    mechanically harvested for commercial sale. Smaller trees
    and shrubs would either be treated by mastication—which
    means using equipment to grind, chip, or break apart brush
    and small trees into small pieces, leaving a “mulch” made
    from wood chips on the forest floor 5—hand-thinning, or

    scattered or piled by hand on the forest floor and burned.
    The vast majority of the trees targeted for treatment will be
    commercially logged and sold.
    On March 13, 2018, the Forest Service issued a Project
    Proposal for the Tecuya Ridge Shaded Fuelbreak Project and
    a letter soliciting public comment on the proposal. Between
    April 2018 and April 2019, Appellants and other interested
    parties submitted comments to the Forest Service, raising
    concerns, among others, that the Project violated 1) NEPA
    by authorizing the sale of commercial wood products
    pursuant to a categorical exclusion, and 2) the Roadless Area
    Conservation Rule by authorizing commercial logging in the
    Antimony IRA.
    In April 2019, Los Padres Forest Supervisor Kevin Elliot
    published a Decision Memo approving the Project. The
    Decision Memo explained that the Forest Service had
    considered the public’s concern regarding “impacts to
    wildlife, the Antimony IRA, and the commercial sale of
    timber and other wood products” but had determined that the
    Project would not “imperil species of concern.”
    Appellants filed a complaint challenging the Forest
    Service’s decision to approve the Project on the grounds that
    the decision violated the Roadless Area Conservation Rule
    and NEPA. The district court granted Appellee’s motion for
    summary judgment and denied Appellants’ motion for
    summary judgment on August 20, 2020. This appeal
    followed. 6

    I. The Forest Service’s Conclusion that the Tecuya
    Ridge Project Is Consistent with the Roadless Area
    Conservation Rule Is Arbitrary and Capricious.
    The Roadless Area Conservation Rule was established in
    2001 7 pursuant to a presidential directive to “initiate a
    associational standing—the right to bring a suit on behalf of their
    members—because their “members would have standing to sue in their
    own right, the interests at stake are germane to the organization’s
    purpose, and neither the claim asserted nor the relief requested requires

    The 2001 Roadless Rule has a somewhat complex history. The
    rule was enjoined before it went into effect, and the Forest Service
    promulgated an alternative rule, see Special Areas; State Petitions for

    70 Fed. Reg. 25,654

    Idaho v. Veneman, 
    313 F.3d 1094
    , 1105 (9th Cir. 2002). In
    promulgating the rule, the Forest Service identified
    58.5 million acres of “inventoried roadless areas,” including
    the Antimony IRA. See 
    id.
    An “Inventoried Roadless Area” (“IRA”) is an area that
    “provide[s] large, relatively undisturbed landscapes that are
    important to biological diversity and the long-term survival
    of many at risk species.” Special Areas; Roadless Area

    , 3,245 (Jan. 12, 2001); see
    also 
    36 C.F.R. § 294.11
    . The Antimony IRA, forested with
    pinyon pine, other conifers, and sagebrush, spans nearly
    40,513 acres across the San Emigdio Mountain range.
    Twenty-four miles long and three miles wide, it lies both
    north of and adjacent to the San Andreas Rift Zone. The
    ridge tops of Antimony provide expansive views of the
    southern San Joaquin Valley. The Antimony IRA also
    provides habitat for California condors, which, according to
    the Final Supplemental Environmental Impact Statement for
    the Southern California National Forests Land Management
    Plan Amendment, use the area “extensively for travel and
    roosting as they soar on uplifted winds along the southern
    boundary of the San Joaquin Valley.”
    The Project authorizes thinning, including commercial
    thinning, of approximately 1,100 acres of forest within the
    Antimony IRA. Generally, timber cutting, sale, or removal

    alternative rule, and reinstating the original 2001 rule, in 2009. See
    California ex rel. Lockyer v. U.S. Dep’t of Agric., 
    575 F. 3d 999

    in areas like the Antimony IRA are prohibited by the
    Roadless Area Conservation Rule because those activities
    “have the greatest likelihood of altering and fragmenting
    landscapes, resulting in immediate, long-term loss of
    roadless area values and characteristics.” Special Areas;

    ]. Third, the
    harvest must maintain or improve one or more of the

    The Forest Service concluded that the Project complies
    with the Roadless Rule because it seeks to reduce the risk of
    uncharacteristic wildfire effects, a purpose specifically
    identified in 
    36 C.F.R. § 294.13

    , and removes generally smaller trees
    with a diameter of less than 21 inches at breast height
    (“dbh”) within the Antimony IRA. Appellants, however,
    argue that the Forest Service has failed to substantiate its
    assertion that trees measuring 21-inches dbh are “generally
    small diameter timber” or explain how the Project will
    maintain or improve one of the “roadless area
    characteristics” listed in 
    36 C.F.R. § 294.11
    .
    The Court disagrees with Appellants on the latter
    contention and finds that the Forest Service has adequately
    explained its determination that the Project will maintain or
    improve one of the roadless area characteristics listed in
    
    36 C.F.R. § 294.11
    . For instance, the fourth characteristic
    covers the “[h]abitat for threatened, endangered, proposed,
    candidate, and sensitive species” and the Forest Service’s
    Decision Memo finds that “[t]he project would benefit
    California condors by treating fuels to help prevent large,
    LOS PADRES FORESTWATCH V. USFS                   15
    high intensity stand replacement wildland fire that could
    eliminate roosting habitat over a larger area.”
    But because the Forest Service has indeed failed to
    explain its determination that 21-inch dbh trees are
    “generally small diameter timber” within the meaning of the
    Roadless Rule, its decision to approve the Project was
    arbitrary and capricious.
    A. The Forest Service’s Determination that 21-inch
    dbh Trees Are “Generally Small Diameter
    Timber” Is Arbitrary and Capricious.
    “The intent of the [Roadless Area Conservation Rule] is
    to limit the cutting, sale, or removal of timber to those areas
    that have become overgrown with smaller diameter trees.”
    Special Areas; Roadless Area Conservation, 66 Fed. Reg.
    at 3,257. In promulgating the Rule, the Forest Service
    specifically chose not to define “what constitutes ‘generally
    small diameter timber’” because “[s]uch determinations are
    best made through project specific or land and resource
    management plan NEPA analyses,” as guided by certain
    ecological considerations. Id.
    Risk of fire is one of these considerations. The Forest
    Service noted that “areas that have become overgrown with
    shrubs and smaller diameter trees creating a fuel profile that
    acts as a ‘fire ladder’ to the crowns of the dominant overstory
    trees may benefit ecologically from thinning treatments that
    cut and remove such vegetation.” Id. The notice of adoption
    of the final version of the Rule specifically explains that
    “[t]hinning of small diameter trees, for example, that became
    established as the result of missed fire return intervals due to
    fire suppression and the condition of which greatly increases
    the likelihood of uncharacteristic wildfire effects,” is
    permissible under the Rule. Id.
    16         LOS PADRES FORESTWATCH V. USFS
    The Project permits mechanical thinning of trees less
    than 21-inches dbh inside the Antimony IRA to prevent
    uncharacteristic wildfire effects.    The Forest Service
    contends that trees less than 21-inches dbh are “generally
    small diameter timber” consistent with 
    36 C.F.R. § 294.13
    .
    But the Court finds no evidence in the record to support the
    Forest Service’s determination.

    625 F.3d 1092
    , 1121 (9th Cir. 2010)).
    The Forest Service has failed to articulate a satisfactory
    explanation—in the administrative record, in briefing, and at
    oral argument—for its determination that the 21-inch dbh
    trees that inhabit the Project area are “generally small”
    within the meaning of the Roadless Rule. Problematically,
    LOS PADRES FORESTWATCH V. USFS                  17
    the Forest Service fails to provide evidence of the average or
    median dbh of the trees within the Tecuya Ridge Project area
    at all. It is impossible to tell, from the record, which size
    classes of trees inhabit the Project area and whether 21-inch
    dbh trees can properly be considered “small” within those
    classes. Instead, the Decision Memo approving the Project
    merely contains a bare assertion—with no supporting
    analysis—that the 21-inch dbh trees are “smaller trees”
    consistent with the Roadless Area Conservation Rule.
    The Briefing Paper accompanying the Decision Memo,
    which references the Los Padres Land Management Plan,
    also fails to provide clarity. The Los Padres Land
    Management Plan defines large-diameter trees as those of
    over 24-inches dbh. The Forest Service appears to argue that
    any tree with a dbh of less than 24 inches can be considered
    a “generally small diameter tree.” But the Court cannot
    determine why, in the Forest Service’s view, the difference
    between a “generally small” tree and a “large-diameter tree”
    is merely three inches dbh because the Forest Service has
    failed to provide any information that would help the Court
    to do so. Indeed, the Land Management Plan’s declaration
    that 24-inch dbh trees are large-diameter trees leads the
    Court to conclude that a 21-inch dbh tree is, at best, a
    medium-sized tree, not a “generally small” tree as
    contemplated by the Roadless Rule.
    Other evidence available in the record tends to confirm
    that trees of up to 21-inches dbh are not “generally small.”
    In an Environmental Assessment for another nearby project,
    the Frazier Mountain Project, the Forest Service noted that
    “larger diameter” trees were those with a dbh greater than
    ten inches. Although the Forest Service contends that the
    Frazier Mountain Project Environmental Assessment is
    irrelevant here because that project thinned timber stands
    18         LOS PADRES FORESTWATCH V. USFS
    primarily overstocked with different tree species—Jeffrey
    pine—the Court is not convinced. Jeffrey pine, a type of
    coniferous tree, is a component of mixed-conifer forests and
    a type of tree found within the Tecuya Project area. Because
    the Frazier Project area is located in close proximity with the
    Tecuya Ridge Project area and likely contains a similar stand
    composition, the Forest Service has failed to justify its
    determination that “larger diameter” trees in the Frazier
    Project area have a dbh greater than ten inches while “small
    diameter” trees in the Tecuya Ridge Project area have a dbh
    of up to 21 inches.
    Even assuming that the stand composition in the Frazier
    Mountain Project area differs substantially from the stand
    composition in the Tecuya Ridge Project area, the Forest
    Service has failed to provide any data comparing the average
    dbh of trees within the Frazier Mountain Project area with
    the average dbh of trees in the Tecuya Ridge Project area to
    support its conclusion that “small” trees in the Tecuya Ridge
    are much larger than even the “large” trees on Frazier
    Mountain. If the Forest Service had shown that trees on
    Frazier Mountain have a generally smaller dbh on average
    than the mixed conifer and pinyon-juniper trees on the
    Tecuya Ridge, the Court might have deferred to its
    determination that trees of up to 21 dbh in mixed conifer and
    pinyon-juniper dominated stands in the Project area are
    properly considered “small.” But the Forest Service did not
    attempt to articulate this explanation or, indeed, provide any
    information at all on the average dbh of the trees located
    within the Tecuya Project area.
    In attempting to support its determination that the Project
    Decision Memo complies with the Roadless Rule, the Forest
    Service notes that the Roadless Rule’s definition of generally
    small timber is “flexible” and allows Forest Service experts
    LOS PADRES FORESTWATCH V. USFS                   19
    to determine what timber is “generally small” based on
    project-specific goals and ecological considerations. It
    argues that 21-inch dbh trees must be removed within the
    Project area to “meet the desired conditions of the proposed
    [Project] to a 90 percent effective level,” and urges the Court
    defer to its “technical expertise.” But although the Forest
    Service may indeed apply its technical expertise to
    determine which “generally small” trees pose an
    uncharacteristically high risk of fire spread and intensity, see
    Special Areas; Roadless Area Conservation, 66 Fed. Reg. at
    3,257, the Forest Service provides no evidence that it has
    actually performed the technical analysis necessary to
    identify them.
    For instance, the Decision Memo for the Project states
    that the Forest Service conducted “stand exams” in the
    project area, “coupled with walk-throughs by Forest
    professionals and data from other sources,” which “confirm
    that existing stand density and structure put the area at risk
    from insects and disease, as well as from wildfire.” But this
    proclamation pertains solely to the Forest Service’s rationale
    for the Project—it does not substantiate the Forest Service’s
    determination that 21-inch dbh trees are “generally small” or
    why 21-inch dbh trees, specifically, are creating the risk of
    wildfire the Project seeks to ameliorate. In fact, the Forest
    Service has never explained what a “stand exam” or “walk-
    through” entails, and how the data gleaned from those
    activities helped it to determine that the Project complies
    with the Roadless Rule. By failing to explain why 21-inch
    dbh trees are the type of “generally small trees” the Roadless
    Rule permits the Forest Service to harvest, the Forest Service
    has failed to show that it has complied with the intent of the
    Roadless Rule to “limit the cutting, sale, or removal of
    timber to those areas that have become overgrown with
    20         LOS PADRES FORESTWATCH V. USFS
    smaller diameter trees.” Special Areas; Roadless Area
    Conservation, 66 Fed. Reg. at 3,257.
    To be clear, the Court does not require the Forest Service
    to undertake any particular method of providing a reasoned
    explanation for its choice to designate trees of up to 21-
    inches dbh as “generally small.” The United States Supreme
    Court has continually affirmed that “agencies should be free
    to fashion their own rules of procedure.” Vermont Yankee
    Nuclear Power Corp. v. Nat. Res. Def. Council, Inc.,
    
    435 U.S. 519
    , 544 (1978). “[A] reviewing court may not,
    after determining that additional evidence is requisite for
    adequate review, proceed by dictating to the agency the
    methods, procedures, and time dimension of the needed
    inquiry.” Fed. Power Comm’n v. Transcon. Gas Pipe Line
    Corp., 
    423 U.S. 326
    , 333 (1976). But where “the decision
    of the agency ‘is not sustainable on the administrative record

    remanded . . . for further consideration.”

     (quoting

    The Forest Service’s determination that the Project is
    consistent with the Roadless Area Conservation Rule is not
    sustainable on the current administrative record. The Court
    cannot discern how the Forest Service arrived at the 21-inch
    dbh number. The Court thus remands this case to the Forest
    Service to substantiate its conclusion that 21-inch dbh trees
    are “generally small” within the project area, consistent with
    the Roadless Rule. See Blue Mountains Biodiversity Project
    v. Blackwood, 
    161 F.3d 1208
    , 1214 (9th Cir. 1998) (finding

    B. The Forest Service’s Determination that the
    Project Will “Maintain or Improve” the
    Antimony Roadless Area’s Characteristics Is Not
    Arbitrary and Capricious.
    Appellants further allege that the Forest Service violated
    
    36 C.F.R. § 294.13
     of the Roadless Rule by failing to
    provide “any explanation at all” to establish that the logging
    of 21-inch dbh trees will “maintain or improve one or more
    of the roadless area characteristics as defined in § 294.11.”
    But in this case, the Forest Service has met its obligations
    under State Farm to “articulate a satisfactory explanation for
    its action including ‘a rational connection between the facts
    found and the choice made.’” State Farm Mut. Auto. Ins.
    Co., 
    463 U.S. at 43
     (quoting Burlington Truck Lines,
    
    371 U.S. at 168
    ).
    The Forest Service avers that the Project will maintain or
    improve habitat conditions for threatened, endangered,
    proposed, candidate, and sensitive species, a roadless area
    characteristic defined by 
    36 C.F.R. § 294.11
    . That assertion
    is substantiated in the Decision Memo for the Project, which
    includes the Forest Service’s determination that “in some
    situations, cutting or removal of small diameter timber [in
    the Project area] may be needed for recovery or conservation
    of threatened, endangered, proposed or sensitive species to
    improve stand structure or reduce encroachment into
    meadows or other natural openings.” For instance, the
    California condor, an endangered species, frequently flies
    over the Project area and may use the Project area to roost or
    nest. The Forest Service concluded that the Project “would
    benefit California condors by treating fuels to help prevent
    large, high intensity stand replacement wildland fire that
    could eliminate roosting habitat over a larger area” and
    might “improve condor foraging habitat by creating a more
    22         LOS PADRES FORESTWATCH V. USFS
    open area that facilitates finding and catching prey by birds
    like condors that are dependent upon sight for locating
    food.”
    The Project area also contains two sensitive botanical
    species, Hall’s Woolly Sunflower and Flaxleaf Monardella.
    In its Botany Report for the Project, the Forest Service
    concluded that the Project would maintain or improve
    habitat suitability for both of these species because the
    Project will reduce the “risk of mortality from moderate to
    high intensity wildfires.” In addition, it concluded that
    reducing stand density may provide indirect beneficial
    impacts for these species because the Project will create or
    maintain open areas which may provide additional suitable
    habitat. On this record, the Forest Service’s determination
    that the Project will maintain or improve at least one of the
    Antimony Roadless Area’s characteristics was not arbitrary
    and capricious.
    II. The Forest Service’s Decision to “Categorically
    Exclude” the Tecuya Ridge Project from Review in
    an EA or EIS Was Not Arbitrary and Capricious.
    Appellants further contend that the Forest Service’s
    decision to approve the Project violated NEPA. First,
    Appellants argue that the Forest Service improperly
    authorized the Project pursuant to a Categorical Exclusion.
    Second, Appellants argue that the Forest Service’s decision
    to categorically exclude the Tecuya Ridge Project from
    Review in an EA or EIS was arbitrary and capricious
    because the Forest Service failed to analyze fuelbreak
    efficacy as an “extraordinary circumstance” that would
    prevent it from applying a Categorical Exclusion to the
    Project.

    A. The Forest Service’s Determination that CE-6
    Applies to the Project Is Not Arbitrary and
    Capricious.
    NEPA, 
    42 U.S.C. § 4321
     et seq., “declares a broad
    national commitment to protecting and promoting
    environmental quality.” Robertson v. Methow Valley
    Citizens Council, 
    490 U.S. 332
    , 348 (1989). It mandates
    federal agencies to prepare an environmental impact
    statement (“EIS”) for proposed “[f]ederal actions
    significantly affecting the quality of the human
    environment.” 
    42 U.S.C. § 4332
    (C). This statutory
    requirement ensures that federal agencies thoroughly
    consider “detailed information concerning significant
    environmental impacts” before approving certain actions
    and that they make this information “available to [a] larger
    audience that may also play a role in both the
    decisionmaking process and the implementation of that
    decision.” Robertson, 
    490 U.S. at 349
    .
    To effectuate these requirements, Congress established a
    Council on Environmental Quality (CEQ), which
    promulgates “binding regulations implementing the
    procedural provisions of NEPA.” 
    Id. at 354
    ; 
    42 U.S.C. § 4344
    (4). CEQ regulations allow an agency to first prepare
    an environmental assessment (“EA”) for a proposed project
    to determine whether the environmental impact of the
    project is “significant enough to warrant preparation of an
    EIS.” Blackwood, 
    161 F.3d at
    1212 (citing 
    40 C.F.R. § 1508.9
    ).
    But an agency may avoid preparing either an EA or an
    EIS altogether by determining that a proposed action fits
    within certain “categorical exclusions.” 
    40 C.F.R. § 1508.4
    .
    A “Categorical Exclusion” (“CE”) is an action which a
    federal agency has found “do[es] not individually or
    24          LOS PADRES FORESTWATCH V. USFS
    cumulatively have a significant effect on the human
    environment.” 
    Id.
     Normally, proposed actions that fit
    within a categorical exclusion do not require an agency to
    prepare either an environmental impact statement or an
    environmental assessment. 
    Id.
    In approving the Tecuya Ridge Project, the Forest
    Service determined that Categorical Exclusion 6 (CE-6)
    applied and exempted the Project from review in an EA or
    EIS. CE-6 applies to “[t]imber stand and/or wildlife habitat
    improvement activities that do not include the use of
    herbicides or do not require more than 1 mile of low standard
    road construction,” which may include activities such as:
    i.   Girdling trees to create snags;
    ii.   Thinning or brush control to improve
    growth or to reduce fire hazard including
    the opening of an existing road to a dense
    timber stand;
    iii.   Prescribed burning to control understory
    hardwoods in stands of southern pine;
    and
    iv.    Prescribed burning to reduce natural fuel
    build-up and improve plant vigor.
    
    36 C.F.R. § 220.6
    (e)(6).
    Appellants challenge this action, contending that CE-6
    does not apply to the Tecuya Ridge Project because CE-6
    permits only precommercial thinning and the Project
    authorizes commercial thinning.        The Forest Service
    believes that CE-6 applies to the Tecuya Ridge project
    because the Project does not include the use of herbicides or
    LOS PADRES FORESTWATCH V. USFS                  25
    require road construction and because thinning is a timber
    stand improvement activity. The Forest Service interprets
    CE-6 to allow it to commercially thin trees, as long as the
    commercial thinning is used to accomplish forest
    improvement activities.
    We do not decide this question here. In the related case
    Mountain Communities for Fire Safety, Los Padres
    ForestWatch, and Earth Island Institute v. Kevin Elliott and
    the United States Forest Service, No. 20-55660 (9th Cir.
    Feb. 4, 2022), this Court agreed with the Forest Service’s
    reading of CE-6. Therefore, the sole remaining question
    before the Court is whether the Forest Service’s decision to
    apply CE-6 to the Project was arbitrary and capricious
    because it failed to analyze fuelbreak efficacy as a potential
    “extraordinary circumstance” that would prevent application
    of any CE to the Project.
    B. The Forest Service’s Determination that No
    Extraordinary Circumstances Prevent its
    Application of CE-6 to the Project Is Not
    Arbitrary and Capricious.
    Even if a proposed project fits within a CE category, the
    Forest Service cannot opt out of further analysis and
    documentation in an EA or EIS unless “there are no
    extraordinary circumstances related to the proposed action.”
    
    36 C.F.R. § 220.6
    (a). An “extraordinary circumstance” is a
    circumstance “in which a normally excluded action may
    have a significant environmental effect.” 
    40 C.F.R. § 1508.4
    . 
    36 C.F.R. § 220.6
    (b) provides that:
    (1) Resource conditions that should be
    considered in determining whether
    extraordinary circumstances related to a
    proposed action warrant further analysis
    26         LOS PADRES FORESTWATCH V. USFS
    and documentation in an EA or an EIS
    are:
    (i)     Federally listed threatened or
    endangered species or designated
    critical habitat, species proposed
    for Federal listing or proposed
    critical habitat, or Forest Service
    sensitive species;
    (ii)    Flood plains, wetlands,         or
    municipal watersheds;
    (iii)   Congressionally designated areas,
    such as wilderness, wilderness

    areas;
    (iv)    Inventoried roadless area       or

    and
    (vii)   Archaeological sites, or historic
    properties or areas.
    
    36 C.F.R. § 220.6
    (b).
    In addition to these resource conditions, Appellants
    contend that the Forest Service should have analyzed the
    Project’s impacts to public safety as an additional
    LOS PADRES FORESTWATCH V. USFS                   27
    “extraordinary circumstance.” Specifically, Appellants
    contend that the Project’s potential impact to public safety is
    an “extraordinary circumstance” that prevents the Forest
    Service from authorizing the Project pursuant to a CE
    because the Forest Service selected a project location that
    will not reduce the risk of wildfire to the Mt. Pinos
    Communities and is not consistent with the Mt. Pinos
    Community Wildfire Protection Plan.
    That plan, developed in 2006 by the Mt. Pinos
    Communities Fire Safe Council, which includes
    representatives from the U.S. Forest Service, identifies three
    zones that comprise the wildland urban interface. The area
    where man-made structures are located, like homes, is called
    the “Defense Zone.” The “Threat Zone” is a one-quarter
    mile buffer around the Defense Zone that “needs specific
    and intense management and treatments” to “reduce the
    spread and intensity of fire developing or moving” towards
    the Defense Zone. The “Wildland Zone” is the area beyond
    the “Threat Zone.” Approximately ninety-three percent of
    the Proposed Project lies in the Wildland Zone, while the
    remaining seven percent of the Project is located in the
    Threat Zone.
    Appellants contend that the Forest Service’s decision to
    construct a fuelbreak in the Wildland Zone, instead of in the
    Threat Zone, is arbitrary and capricious. They note that the
    original, 2006 version of the Community Wildfire Protection
    Plan did not include any projects located within the Wildland
    Zone, although the Plan was updated to add the Tecuya
    Ridge Fuel Break Project, as well as other projects located
    in the Wildland Zone, in 2009.
    28           LOS PADRES FORESTWATCH V. USFS
    Appellants also point to the results of a scientific study 8
    showing that “constructing fuel breaks in remote,
    backcountry locations will do little to save homes during a
    wildfire because most firefighters will be needed to protect
    the wildland-urban interface, and fires will not be stopped by
    those fuel breaks that are located farther away.” That study
    concluded that “[f]irefighter access to fuel breaks was the
    most influential factor in fuel treatment outcome” for the Los
    Padres Forest.
    The Forest Service, however, was not required to
    examine impacts to public safety or fuelbreak location
    efficacy in analyzing whether extraordinary circumstances
    prevented the use of CE-6 for the Project. Consistent with
    
    36 C.F.R. § 220.6
    , the Forest Service analyzed each resource
    condition and determined that the Project would have “no
    significant impact” on each. Although the list of resource
    conditions located at 
    36 C.F.R. § 220.6
    (b) is not intended to
    be exhaustive, NEPA merely permits, rather than requires,
    the Forest Service to consider additional factors during its
    extraordinary circumstances review. See, e.g., NEPA
    Procedures, 
    73 Fed. Reg. 43,084
    , 43,091 (July 24, 2008)
    (“The list of resource conditions is intended as a starting
    place and does not preclude consideration of other factors or
    conditions by the responsible official with the potential for
    significant environmental effects.”). Courts have therefore
    rejected the contention that the Forest Service is required to
    analyze additional factors on top of the specified resource
    conditions in determining whether extraordinary
    circumstances prevent the application of a CE. See All. for
    the Wild Rockies, 979 F. Supp. at 1127 (finding that the Fish

    California National Forests, Forest Ecology and Mgmt., Feb. 2011,

    and Wildlife Service did not need to analyze certain factors
    set out under a different regulation related to bull trout
    habitat in determining “no extraordinary circumstances”
    prohibited its application of CE-6 to a proposed project).
    Regardless, the Forest Service’s decision to locate the
    Tecuya Ridge Project in the “Wildland Zone” instead of the
    “Threat Zone” was not arbitrary and capricious. The Los
    Padres National Forest Strategic Community Fuelbreak
    Improvement Project Fire/Fuels Report states that while
    most existing fuelbreaks are in “high hazard chaparral
    areas,” a few fuelbreaks, like the one contemplated here, “are
    in coniferous forest and serve to limit fire spread from or
    towards communities or timber stands in poor condition.”
    The Cuddy Valley/Tecuya Stand Improvement Projects
    Fire/Fuels Report also notes that “[t]o reduce the threat of
    spotting distance from firebrands (spotting potential), fuels
    would need to be reduced both near and at some distance
    from the WUI [Wildland Urban Interface].” (emphasis
    added). The Decision Memo for the Project further explains
    that the Forest Service chose the project location to
    strategically “connect to past and future treatment areas on
    both public and adjacent private lands.” It was therefore
    reasonable for the Forest Service to conclude that the Project
    location will “provide a buffer between developed areas and
    wildlands,” one of the goals of the Mt. Pinos Community
    Wildfire Protection Plan.
    Nor is there evidence that the proposed fuelbreak will be
    constructed in a “remote backcountry location” that will fail
    to facilitate firefighter access. The Tecuya Ridge fuelbreak
    will be located around communities within the wildland-
    urban intermix, including Pine Mountain Club, Pinon Pines
    Estates, Lake of the Woods, and Frazier Park. Sixty-six
    percent of the Project overlaps with the Antimony IRA,
    30         LOS PADRES FORESTWATCH V. USFS
    which is linearly shaped and adjacent to major roadways.
    There are 3.9 miles of Forest system road, 1.1 miles of
    county roads, and approximately 1.5 miles of Forest
    permitted roads in the Antimony IRA. Firefighters may
    access the Antimony IRA via developed roads and trails.
    Thus, the fuelbreak location does not appear to be too remote
    for firefighters to approach in the case of wildfire.
    Whether the location of the fuelbreak proposed for the
    Tecuya Ridge Project will serve to protect the Mt. Pinos
    Communities from wildfire is “a classic example of a factual
    dispute the resolution of which implicates substantial agency
    expertise.” Marsh v. Or. Nat. Res. Council, 
    490 U.S. 360
    ,

    decision to place the Tecuya Ridge Project within the
    Wildland Zone with evidence in the record, its decision was
    not arbitrary and capricious. The Court declines to substitute
    Appellants’ judgment for that of the agency on this point.

    CONCLUSION
    Because the Forest Service’s determination that the
    Tecuya Ridge Shaded Fuelbreak Project complies with the
    Roadless Area Conservation Rule is arbitrary and capricious,
    we VACATE the district court’s order granting summary
    judgment to Appellees and the Forest Service’s Decision
    Memo approving the Tecuya Ridge Shaded Fuelbreak
    Project and REMAND this case to the Forest Service to
    provide adequate substantiation for its determination that 21-
    inch dbh trees are “generally small diameter timber” within
    the Project Area.
    LOS PADRES FORESTWATCH V. USFS                   31
    R. NELSON, Circuit Judge, dissenting:
    I agree with Sections I.B and II of the majority opinion.
    As the majority recognizes, the Forest Service “has
    adequately explained its determination that the Project will
    maintain or improve one of the roadless area
    characteristics.” Maj. Op. 14. The majority wrongly holds,
    however, that the Forest Service’s determination that 21-
    inch dbh trees are “small diameter” was arbitrary or
    capricious under the Administrative Procedure Act. I
    therefore respectfully dissent as I would deny the petition for
    review.
    Under the Roadless Rule, the Forest Service can only
    approve the commercial thinning of “generally small
    diameter timber.”        Special Areas; Roadless Area
    Conservation, 
    66 Fed. Reg. 3244
    , 3273 (Jan. 12, 2001)
    (previously codified at 
    36 C.F.R. § 294.13
    ). The majority
    assumes that this requires the Forest Service to explain in
    detail why 21 inches dbh is small diameter. But such a
    detailed explanation is not required. As long as the Forest
    Service considers the factors laid out in the relevant federal
    regulations, the agency need not provide a separate
    exhaustive explanation of what trees are generally small
    diameter.
    As the majority acknowledges, the regulations do not
    define what constitutes “generally small diameter timber.”
    Maj. Op. 16. A single definition for “small diameter timber”
    makes no sense; such determinations must be project-
    specific and guided by local ecological considerations in
    which the Forest Service has expertise. 66 Fed. Reg.
    at 3257. The regulations require only that the Forest Service
    use its expertise to determine which trees are small diameter
    depending on “the great variation in stand characteristics
    between vegetation types in different areas,” “the
    32          LOS PADRES FORESTWATCH V. USFS
    characteristics and interrelationships of plant and animal
    communities associated with the site and the overall
    landscape,” and how the “cutting or removal” of trees will
    “affect the potential for future development of the stand.” Id.
    The Forest Service adequately complied with this
    administrative directive.
    Over the course of preparing the Tecuya Ridge Project
    Proposal, the Forest Service thoroughly analyzed local
    plant-animal relationships and the future development of the
    tree stands in the Project, including how removal “would
    mimic the role and legacies of natural disturbance regimes.”
    See 66 Fed. Reg. at 3257. It completed a botany report, a
    fire fuels report, two decision memoranda, and a briefing
    paper that specifically analyzed whether the Project
    complied with CE-6 and the Roadless Rule. Silvicultural
    specialists surveyed and conducted exams and walk-
    throughs in the Project area. The Forest Service identified
    forest stands that were overstocked due to their size and
    density, subject to insect attack due to resource competition,
    and at imminent risk of creating a “fire ladder” fuel profile.
    It determined that forest stands over 120 square feet per acre
    needed to be thinned to at least 80 feet per acre. It calculated
    the size of trees that should be retained for California
    condors and northern goshawks. And it decided that—to
    meet the stated goals that the majority accepts, Maj.
    Op. 15—only smaller diameter trees up to 21 inches dbh
    should be cut for safety or operability reasons, especially
    early seral species including Jeffrey and pinyon pine.
    After this comprehensive ecological analysis, the Forest
    Service concluded that trees under 21 inches dbh “needed to
    be thinned to meet the desired conditions of the proposed
    action to a 90 percent effective[ness] level.” As the majority
    notes, “[e]ven when an agency explains its decision with
    LOS PADRES FORESTWATCH V. USFS                       33
    ‘less than ideal clarity,’ a reviewing court will not upset the
    decision on that account ‘if the agency’s path may
    reasonably be discerned.’”          Alaska Dep’t of Env’t
    Conservation v. EPA, 
    540 U.S. 461
    , 497 (2004) (quoting
    Bowman Transp., Inc. v. Ark.–Best Freight Sys., Inc.,
    
    419 U.S. 281
    , 286 (1974)). Here, the record allows us to
    reasonably discern the Forest Service’s “path” in
    considering the regulatory requirements. See 
    id.
     That is
    enough to survive our deferential review for arbitrary or
    capricious agency action. See Nat’l Family Farm Coal. v.
    EPA, 
    966 F.3d 893
    , 923 (9th Cir. 2020) (agency decision is
    arbitrary or capricious “only if the agency relied on factors
    Congress did not intend it to consider, . . . or is so
    implausible that it could not be ascribed to a difference in
    view or the product of agency expertise” (citation omitted)).
    The majority reaches the opposite conclusion by
    improperly comparing the Tecuya Ridge Project here to the
    Frazier Mountain Project, which it says “likely contains a
    similar stand composition.” Maj. Op. 18. One of three
    alternatives presented in that Project deemed trees large
    diameter at 10 inches dbh. True, the Tecuya Ridge Project
    and the Frazier Mountain Project are located nearby in the
    same national forest. But the Los Padres National Forest
    spans approximately 1.75 million acres, ranges in elevation
    by over 8,000 feet, and consists of two separate land
    divisions. 1 As the Forest Service explains, the two projects
    contain different compositions of tree species. Nothing in
    the record undermines that finding. Judges are hardly

    equipped, as the majority does, to second-guess the agency’s
    evaluation of a forest stand’s composition. 2 Especially when
    the regulations require that the Forest Service’s analysis be
    done on a project-by-project basis, the agency need not
    explain why small diameter may vary between projects. We
    cannot rely on the Frazier Mountain Project to provide a
    workable definition of small diameter trees for the Tecuya
    Ridge Project. 66 Fed. Reg. at 3257 (determinations best
    made through “project specific . . . analyses”).
    We likewise cannot assume, as the majority does, that
    because the Los Padres Land Management Plan describes
    large diameter trees as greater than 24 inches dbh, trees up
    to 21 inches dbh are “at best, . . . medium sized.” Maj.
    Op. 17. The Plan’s reference to 24 inches dbh as large
    diameter only refers to “shade intolerant conifer species.”
    According to the record, shade-intolerant conifers include
    ponderosa pine, which are not listed as within the Project.
    Nothing in the record suggests that the trees in the Project
    are shade intolerant. Further, if large diameter trees, sixteen
    years ago when the Plan was adopted, were “old growth”
    trees, then today those old growth trees would be even larger.
    Even if we could rely on the Plan’s reference, small diameter
    trees today would be smaller than or even up to 24 inches
    dbh. The federal regulations do not suggest that the Forest
    Service is bound by past data. Instead, they direct the Forest
    Service to consider the “potential for future development of
    the stand.” 66 Fed. Reg. at 3257. In reality, all trees can be
    2
    For instance, the majority states that the Tecuya Ridge Project is
    filled with “Singleleaf pinyon-California juniper” trees. Maj. Op. 6. But
    “singleleaf pinyon” and “California juniper” are two different tree
    species, and “Single-leaf pinyon-California juniper” in the Los Padres
    Land Management Plan describes a woodland including trees of those
    two species.
    LOS PADRES FORESTWATCH V. USFS                   35
    small or large diameter—as long as the record shows, as it
    does here, that the Forest Service adequately considered the
    regulatory factors.
    Finally, the majority ignores basic rules of
    administrative law. The majority correctly notes that we
    cannot “require the Forest Service to undertake any
    particular method of providing a reasoned explanation for its
    choice.” Maj. Op. 20. But then it ignores that principle and
    finds that the Forest Service failed to provide “the average
    or median dbh of the trees.” Id. at 16–17. Neither the
    Roadless Rule nor the related regulations require such an
    analysis. To the contrary, the regulations list very different
    considerations—namely, local “vegetation types in different
    areas” and the “future development of the stand”—which
    seems to exclude the average or mean dbh as a basis for
    determining small diameter. 66 Fed. Reg. at 3257. Indeed,
    the majority’s requirement to analyze the average or mean
    dbh would be particularly detrimental to old growth forest
    stands because it would allow thinning of larger trees
    without consideration of the regulatory factors. Regardless,
    the court may not “impose upon the agency its own notion
    of which procedures are best.” Vt. Yankee Nuclear Power
    Corp. v. Nat. Res. Def. Council, 
    435 U.S. 519
    , 549 (1978)
    (internal quotation marks omitted).
    The right question is not “what trees objectively fall into
    the category of small diameter trees?”—it is “did the Forest
    Service perform project-specific analyses to support its
    conclusion that less-than-21-inch dbh trees should be
    thinned under project-specific circumstances?” The Forest
    Service did not seek to establish a one-size-fits-all rule that
    21 inches dbh was small diameter in all projects. Instead, it
    determined that the Tecuya Ridge Project included
    mechanically thinning trees that were less than 21 inches dbh
    36           LOS PADRES FORESTWATCH V. USFS
    and that the portion of the Project encompassing the
    Antimony IRA complies with the Roadless Rule. 3 The
    Forest Service explicitly stated that “[t]his diameter would
    be needed to be thinned to meet the desired conditions.”
    This conclusion was neither arbitrary nor capricious under
    the discretion granted to the Forest Service by federal
    regulations. I therefore respectfully dissent.
    3
    About 48 percent of the total 40,153 acres of the Antimony IRA,
    which overlaps with the Project, is pinyon woodlands, sagebrush, and
    other conifers. Tree thinning would occur on only 1,075 acres of the
    Antimony IRA, or less than 3 percent of the IRA.
