    Appeal from the United States District Court
    for the Western District of Texas
    Before KING, JONES, and DENNIS, Circuit Judges.
    KING, Circuit Judge:
    The United States Fish and Wildlife Service listed the Golden-Cheeked
    Warbler as an endangered species in 1990. Approximately twenty-six years
    later, the Service denied a petition asking it to delist the Warbler. The General
    Land Office of the State of Texas claims that both of these decisions are invalid,
    but its challenge to the Service’s decision to list the Warbler is untimely. We
    agree with the General Land Office, however, that the Service applied the
    Case: 19-50178     Document: 00515272659    Page: 2   Date Filed: 01/15/2020
    No. 19-50178
    incorrect standard when reviewing the delisting petition. Consequently, we
    conclude that the Service’s decision denying the delisting petition was
    arbitrary and capricious, vacate that decision, and remand to the Service for
    further proceedings.
    I.
    The General Land Office identifies three issues associated with the
    Service’s decision to list the Warbler and its decision to deny the delisting
    petition. First, the General Land Office contends that the Service violated the
    Endangered Species Act (ESA), Pub. L. No. 93-205, 87 Stat. 884 (1973) when
    it listed the Warbler as endangered, because the Service never designated the
    Warbler’s critical habitat. Second, the General Land Office argues that both of
    the Service’s decisions concerning the Warbler violated the National
    Environmental Policy Act (NEPA), Pub. L. No. 91-190, 83 Stat. 852 (1970).
    Third, the General Land Office asserts that the Service violated the ESA and
    its implementing regulations when reviewing the delisting petition. Because
    of the central role the ESA and NEPA play in the General Land Office’s claims,
    we begin by describing how those statutes operate.
    A. The Endangered Species Act
    The ESA affords certain protections to endangered and threatened
    species. 16 U.S.C. §§ 1533, 1536, 1538, 1539. An endangered species is defined
    as “any species which is in danger of extinction throughout all or a significant
    portion of its range,” 
    id. § 1532(6),
    while a threatened species is “any species
    which is likely to become an endangered species within the foreseeable future,”
    
    id. § 1532(20).
    The ESA lists five biological factors that can cause a species to
    be endangered or threatened:
    (A) the present or threatened destruction, modification, or
    curtailment of its habitat or range;
    (B) overutilization for commercial, recreational, scientific, or
    educational purposes;
    2
    Case: 19-50178     Document: 00515272659       Page: 3   Date Filed: 01/15/2020
    No. 19-50178
    (C) disease or predation;
    (D) the inadequacy of existing regulatory mechanisms; or
    (E) other natural or manmade factors affecting its continued
    existence.
    16 U.S.C. § 1533(a)(1). Whether a species is endangered or threatened is
    determined “solely on the basis of the best scientific and commercial data
    available . . . after conducting a review of the status of the species and after
    taking into account” existing conservation efforts. 
    Id. § 1533(b)(1)(A).
    Similarly, determinations regarding the critical habitat of a species must be
    determined “on the basis of the best scientific data available and after taking
    into consideration the economic impact, the impact on national security, and
    any other relevant impact, of specifying any particular area as a critical
    habitat.” 
    Id. § 1533(b)(2);
    see also 
    id. § 1532(5)(A)
    (defining critical habitat).
    Determinations regarding whether a species is endangered or
    threatened are made through a modified form of notice-and-comment
    rulemaking. 16 U.S.C. § 1533(b)(4). As relevant to this case, upon publication
    of a final determination that a species is endangered or threatened, its critical
    habitat should, “to the maximum extent prudent and determinable,” be
    designated “concurrently with” that publication. 
    Id. § 1533(a)(3)(A).
    Even if the
    critical habitat of an endangered or threatened species is not designated
    concurrently, it must be designated, “to the maximum extent prudent,” within
    two years of publication of the proposed rule classifying the species. 
    Id. § 1533(b)(6)(C)(ii).
          The ESA directs the Secretary of the Interior to publish and maintain
    lists of all endangered and all threatened species. 16 U.S.C. § 1533(c)(1). These
    lists “shall . . . specify with respect to each such species over what portion of its
    range it is endangered or threatened, and specify any critical habitat within
    such range.” 
    Id. The ESA
    calls for, “at least once every five years, a review of
    3
    Case: 19-50178       Document: 00515272659         Page: 4    Date Filed: 01/15/2020
    No. 19-50178
    all species included in a list which is published pursuant to [the ESA] and
    which is in effect at the time of such review.” 
    Id. § 1533(c)(2)(A).
    Following this
    review, the ESA requires a determination of whether any species should be
    removed from the lists or moved from one list to the other. 
    Id. § 1533(c)(2)(B).
    Such a determination is made “in accordance” with the provisions governing
    an initial decision to list a species. 
    Id. § 1533(c)(2).
           Any interested party can petition to add or remove a species from these
    lists. 16 U.S.C. § 1533(b)(3). Within ninety days of receiving such a petition,
    there should, “[t]o the maximum extent practicable,” be a finding “as to
    whether the petition presents substantial scientific or commercial information
    indicating that the petitioned action may be warranted.” 
    Id. § 1533(b)(3)(A).
    If
    this ninety-day finding is negative, then it is subject to judicial review. 
    Id. § 1533(b)(3)(C)(ii).
    If the ninety-day finding is positive, then the status of the
    species must be reviewed. 16 U.S.C. § 1533(b)(3)(B). This review, called a
    twelve-month review, is followed by a finding regarding whether the petitioned
    action is warranted, which must be made within twelve months of the
    petition’s receipt. 
    Id. The ESA
    does not provide details regarding what
    constitutes substantial information, the amount of information required for a
    positive ninety-day finding, but implementing regulations fill that void.
    Specifically, when the Service denied the petition to delist the Warbler, then-
    applicable regulations 1 defined substantial information as “that amount of
    information that would lead a reasonable person to believe that the measure
    proposed in the petition may be warranted.” 50 C.F.R. § 424.14(b)(1) (2014).
    1 After the Service denied the delisting petition, the regulations implementing the
    ESA petition process changed significantly. Substantial scientific or commercial information
    is now defined as “credible scientific or commercial information in support of the petition’s
    claims such that a reasonable person conducting an impartial scientific review would
    conclude that the action proposed in the petition may be warranted.” 50 C.F.R.
    § 424.14(h)(1)(i).

    B. The National Environmental Policy Act
    Congress passed NEPA “to promote human welfare by alerting
    governmental actors to the effect of their proposed actions on the physical
    environment.” Metropolitan Edison Co. v. People Against Nuclear Energy, 
    460 U.S. 766
    , 772 (1983). Under NEPA, federal agencies must include an
    environmental impact statement in every “recommendation or report on . . .
    major Federal actions significantly affecting the quality of the human
    environment.” 42 U.S.C. § 4332(C); accord City of Dallas v. Hall, 
    562 F.3d 712
    ,
    717 (5th Cir. 2009). An environmental impact statement is “a detailed
    statement by the responsible official” regarding, among other things, the
    “environmental    impact    of   the   proposed   action”   and    “any   adverse
    environmental effects which cannot be avoided should the proposal be
    implemented.” 42 U.S.C. § 4332(C).
    Regulations promulgated by the Council on Environmental Quality
    instruct agencies on how to determine whether an environmental impact
    statement is necessary for a particular proposed action, i.e., whether the
    proposed action has a significant impact on the human environment. Coliseum
    Square Ass’n v. Jackson, 
    465 F.3d 215
    , 224 (5th Cir. 2006). Under those
    regulations, agencies generally perform an environmental assessment, a
    “rough cut, low-budget environmental impact statement,” to determine
    whether a full-blown environmental impact statement is necessary. City of
    
    Dallas, 562 F.2d at 717
    ; accord 40 C.F.R. § 1508.9(a)(1). If, as a result of an
    environmental assessment, an agency concludes that an environmental impact
    statement is not necessary, the agency issues a finding of no significant impact,
    “indicating that no further study of environmental impacts is warranted. City
    of 
    Dallas, 562 F.3d at 718
    . In essence, agencies usually prepare environmental
    assessments to determine whether proposed actions will have any significant
    5
    Case: 19-50178       Document: 00515272659          Page: 6     Date Filed: 01/15/2020
    No. 19-50178
    environmental effects, in which case agencies prepare environmental impact
    statements to determine what those effects will be.
    Before September 21, 1983, the Service prepared environmental
    assessments for its decisions regarding whether to list or delist species. See
    Preparation of Environmental Assessments for Listing Actions Under the
    Endangered Species Act, 48 Fed. Reg. 49,244, 49,244 (Oct. 25, 1983). As of that
    date, however, the Service ceased preparing environmental assessments for
    such decisions. 
    Id. The Service
    did so because it “accepted [the Council on
    Environmental Quality’s] judgment that . . . listing actions are exempt from
    NEPA review ‘as a matter of law.’” 
    Id. 2 II.
           The Golden-Cheeked Warbler is a songbird with distinctive yellow
    coloring that breeds exclusively in certain parts of Texas, although it travels
    to other countries in the winter. Final Rule to List the Golden-cheeked Warbler
    as Endangered, 55 Fed. Reg. 53,153, 53,154 (Dec. 27, 1990). The Warbler’s
    breeding range “coincides closely with the range of Juniperus ashei (Ashe
    juniper),” perhaps because the Warbler “depends on Ashe juniper for nesting
    materials and substrate, and singing perches.” 
    Id. While the
    Warbler nests in
    some oak trees as well as in Ashe junipers, “[e]ven nests in other tree species
    contain long strips of Ashe juniper bark.” 
    Id. Ashe junipers
    “begin sloughing
    bark near the base at about 20 years, and at the crown by 40 years,” so the
    2  The Service gave three additional reasons for its decision to cease preparing
    environmental assessments: (i) none of the approximately 130 environmental assessments
    prepared by the Service in connection with listing decisions resulted in an environmental
    impact statement; (ii) the Sixth Circuit had ruled, in Pacific Legal Foundation v. Andrus, 
    657 F.2d 829
    (1981), that “as a matter of law an Environmental Impact Statement is not required”
    for listing decisions and that “preparing EIS’s on listing actions does not further the goals of
    NEPA or ESA”; and (iii) 1982 amendments to the ESA “require[e] listing decisions under the
    Endangered Species Act to be based solely upon biological grounds and not upon
    consideration of economic or socioeconomic factors.” 48 Fed. Reg. at 49,244-45.

    No. 19-50178
    “presence of mature Ashe junipers is a major requirement for habitat of golden-
    cheeked warblers.” 
    Id. A. The
    Initial Decision to List the Warbler
    In 1990, the Service responded to a petition filed by a private citizen by
    publishing an emergency rule listing the Warbler as endangered for 240 days.
    Emergency Rule to List the Golden-cheeked Warbler as Endangered, 55 Fed.
    Reg. 18,844, 18,844 (May 4, 1990). The Service gave “on-going and imminent
    habitat destruction” in and around Austin, Texas as the justification for its
    emergency rule. 
    Id. The Service
    reasoned that “[a] relatively small loss of
    habitat can contribute to fragmentation of a large area,” which “reduces the
    productivity of the remaining habitat because of increased nest parasitism,
    and increased predation of eggs, young, and adults.” 
    Id. Alongside the
    emergency rule, the Service proposed a rule listing the
    Warbler as endangered on an indefinite basis. Proposed Rule to List the
    Golden-cheeked Warbler as Endangered, 55 Fed. Reg. 18,846, 18,846 (May 4,
    1990). The proposed rule analyzed each of the five factors specified by the ESA
    for making determinations regarding whether a species is endangered or
    threatened, but that analysis focused on the destruction of the Warbler’s
    habitat and the fragmentation of that habitat. 
    Id. at 18,847.
    Specifically, the
    Service found that “[f]ragmentation in urban counties has limited the number
    of suitable size habitat patches to between 16-46 percent of the total vegetation
    structurally suitable for warbler use, and in rural areas the values range from
    11-44 percent.” 
    Id. at 18,847-48.
    In the proposed rule, the Service did not
    designate any critical habitat areas because the Service concluded that such
    areas were “not presently determinable.” 
    Id. at 18,848.
    The Service did,
    however, state its intention to “seek additional agency and public input on
    critical habitat, along with information on the biological status of, and threats
    to, the golden-cheeked warbler” during the comment period and “to use this
    7
    Case: 19-50178     Document: 00515272659     Page: 8   Date Filed: 01/15/2020
    No. 19-50178
    and other information in formulating a decision on critical habitat
    designation.” 
    Id. After receiving
    public comment on the proposed rule, the Service issued
    a final rule listing the Warbler as an endangered species. Final Rule to List
    the Golden-cheeked Warbler as Endangered, 55 Fed. Reg. at 53,153. The final
    rule did not designate critical habitat, because the Service said that “[t]he
    minimum patch size requirements of the golden-cheeked warbler are not
    known at this time.” 
    Id. at 53,159.
    The Service was “presently funding a study
    to determine minimum patch size requirements for this species,” and the
    Service acknowledged that it needed to make a critical-habitat designation by
    May 4, 1992. 
    Id. No such
    designation was ever made.
    B. The Five-Year Review
    Under the ESA, the Service was required to review the Warbler’s status
    at least once every five years, but the first such review was not completed until
    August 26, 2014. Austin Ecological Servs. Field Office, U.S. Fish & Wildlife
    Serv., Golden-Cheeked Warbler (Setophaga Chrysoparia) 5-Year Review:
    Summary     and     Evaluation   2   (2014),   https://www.fws.gov/southwest/es
    /Documents/R2ES/Golden-cheekedWarbler_5YrReview_2014.pdf. That review
    found that the Warbler “is threatened by ongoing and imminent habitat loss”
    and noted that a “recent habitat analysis concluded that there had been an
    estimated 29 percent loss of existing breeding season habitat between 1999-
    2001 and 2010-2011.” 
    Id. at 8.
    According to the five-year review, “[t]he loss of
    habitat through activities such as residential development often results in the
    fragmentation of larger contiguous patches of habitat and increased isolation
    of habitat patches,” which has “been shown to influence habitat quality for
    woodland songbirds” in various ways. 
    Id. at 9.
    Additionally, the five-year
    review identified several other ongoing threats to the Warbler: (i) “reduced oak
    recruitment due to herbivory from native and non-native animals” and “death
    8
    Case: 19-50178      Document: 00515272659      Page: 9    Date Filed: 01/15/2020
    No. 19-50178
    of mature oaks from oak wilt,” id.; (ii) “ongoing destruction and fragmentation
    of pine-oak forests throughout the [Warbler’s] migration and wintering
    habitat,” id.; (iii) increased predation caused by habitat fragmentation, 
    id. at 11;
    (iv) increased risk of catastrophic wildfire’s in the Warbler’s habitat, 
    id. at 13;
    and (v) “accelerating climate change,” which “will likely exacerbate existing
    threats and could result in future threats,” 
    id. at 14.
    Synthesizing this
    information, the five-year review concluded that, “[g]iven the ongoing, wide-
    spread destruction of its habitat, [the Warbler] continues to be in danger of
    extinction throughout its range.” 
    Id. at 15.
    C. The Delisting Petition
    On June 29, 2015, a petition to delist the Warbler was filed by a group of
    petitioners that did not include the General Land Office. Petition to Remove
    the Golden-Cheeked Warbler from the List of Endangered Species at 2, 7-8
    (2015), available at https://ecos.fws.gov/docs/petitions/90100/578.pdf. This
    petition argued that delisting was warranted, because the Warbler population
    and the Warbler breeding habitat were larger than the Service believed when
    it initially listed the Warbler. 
    Id. at 13-14;
    see also 
    id. at 15
    (“The best available
    scientific data today shows that habitat is at least five times larger and the
    warbler population is an order of magnitude larger than estimated in 1990.”).
    Additionally, the delisting petition highlighted a 2015 survey, conducted by the
    Institute of Renewable Natural Resources at Texas A&M, which “summarized
    the extensive research and analysis that has been performed since 1990 and
    concluded that the warbler’s listing status should be re-examined.” 
    Id. at 14.
    D. The Negative Ninety-Day Finding
    After reviewing the delisting petition, the Service found that it “does not
    provide substantial scientific or commercial information indicating that the
    petitioned action may be warranted.” 90-Day Findings on Two Petitions, 81
    Fed. Reg. 35,698, 35,700 (June 3, 2016). Accordingly, the Service did not
    9
    Case: 19-50178   Document: 00515272659      Page: 10   Date Filed: 01/15/2020
    No. 19-50178
    initiate a twelve-month review and denied the delisting petition. 
    Id. The Service
    explained its reasoning at greater length in a sixteen-page
    supplemental document that was mentioned, but not included, in the Federal
    Register. Austin Ecological Servs. Field Office, U.S. Fish & Wildlife Serv., 90-
    Day Finding on a Petition to Remove the Golden-Cheeked Warbler from the List
    of Endangered and Threatened Wildlife (2016) [hereinafter Negative Ninety-
    Day   Finding],   https://www.regulations.gov/document?D=FWS-R2-ES-2016
    -0062-0003. That document contains a concise summary of the Service’s
    reasoning:
    A 5-year review for the golden-cheeked warbler was completed on
    August 26, 2014, in which we recommended that the current
    classification as endangered should not change. The petition does
    not present substantial information not previously addressed in
    the 2014 5-year review for this species and does not offer any
    substantial information indicating that the petitioned action to
    delist the species may be warranted. We acknowledge that the
    known potential range is more extensive than when the golden-
    cheeked warbler was originally listed. However, threats of habitat
    loss and habitat fragmentation are ongoing and expected to impact
    the continued existence of the warbler in the foreseeable future.
    This and other pertinent information was evaluated in the 2014 5-
    year review.
    
    Id. at 10.
    E. The District Court Proceedings
    Following the Service’s decision to deny the delisting petition, the
    General Land Office filed suit against the Service in the United States District
    Court for the Western District of Texas challenging the Warbler’s continued
    listing as an endangered species. The General Land Office argued that the
    Service violated the ESA by listing the Warbler as an endangered species
    without designating the Warbler’s critical habitat. It also argued that the
    Service violated NEPA and its implementing regulations by failing to prepare
    an environmental assessment or an environmental impact statement in
    10
    Case: 19-50178     Document: 00515272659     Page: 11   Date Filed: 01/15/2020
    No. 19-50178
    connection with the Warbler’s initial listing or the decision to deny the
    delisting petition. Additionally, the General Land Office maintained that the
    Service’s negative ninety-day finding—and, hence, the decision to deny the
    delisting petition—was arbitrary and capricious because the Service applied
    the incorrect legal standard.
    The district court dismissed, on statute-of-limitations grounds, the
    General Land Office’s ESA and NEPA claims to the extent that those claims
    challenged the Service’s initial decision to list the Warbler as an endangered
    species. The district court also dismissed the entirety of the General Land
    Office’s NEPA claim under Rule 12(b)(6) of the Federal Rules of Civil
    Procedure, reasoning that the Service’s initial decision to list the Warbler and
    its denial of the delisting petition were not subject to NEPA. Finally, the
    district court granted the Service’s motion for summary judgment on the
    General Land Office’s only remaining claim, that the Service’s negative ninety-
    day finding and the resulting denial of the delisting petition were arbitrary
    and capricious. The General Land Office filed a timely notice of appeal.
    III.
    The General Land Office raises three issues on appeal: (i) whether its
    claims challenging the Service’s initial decision to list the Warbler are time
    barred; (ii) whether the Service’s listing decisions must comply with NEPA’s
    procedural requirements; and (iii) whether the Service applied the correct legal
    standard when issuing the negative ninety-day finding and denying the
    delisting petition. We address each issue in turn.
    A.
    The General Land Office’s claims challenging the Service’s initial
    decision to list the Warbler are time barred. With certain exceptions that are
    not relevant here, “every civil action commenced against the United States
    shall be barred unless the complaint is filed within six years after the right of
    11

    action first accrues.” 28 U.S.C. § 2401(a). The standard rule is that a cause of
    action accrues when a plaintiff is first able to file suit and obtain relief. Doe v.
    United States, 
    853 F.3d 792
    , 801 (5th Cir. 2017) (citing Wallace v. Kato, 
    549 U.S. 384
    , 388 (2007)). This timing requirement is jurisdictional, because it is a
    condition of the United States’ waiver of sovereign immunity. United States v.
    Kubrick, 
    444 U.S. 111
    , 117-18 (1979). “Whether the Government is entitled to
    sovereign immunity from suit presents a question of law that we review de
    novo.” 
    Doe, 853 F.3d at 797
    .
    According to the General Land Office, the ESA required the Service to
    designate the Warbler’s critical habitat within two years of publishing the
    proposed rule listing the Warbler as endangered, i.e., by May 4, 1992, but the
    Service did not do so. It follows that the General Land Office’s ESA claim
    accrued, at the latest, more than two decades before the General Land Office
    filed suit. Consequently, § 2401(a) bars this claim. Ctr. for Biological Diversity
    v. Hamilton, 
    453 F.3d 1331
    , 1335-36 (11th Cir. 2006) (concluding that failure
    to identify critical habitat is not a continuing violation).
    Similarly, NEPA and its implementing regulations impose procedural
    requirements that must, if applicable, be satisfied before an agency becomes
    irreversibly committed to taking a particular action. See Sierra Club v.
    Peterson, 
    717 F.2d 1409
    , 1414 (D.C. Cir. 1983) (“NEPA requires an agency to
    evaluate the environmental effects of its action at the point of commitment.”). 3
    If the Service violated NEPA, that violation was complete—and the General
    3  If it were otherwise, NEPA would not “ensure[] that the agency, in reaching its
    decision, will have available, and will carefully consider, detailed information concerning
    significant environmental impacts” of a proposed action or “guarantee[] that the relevant
    information will be made available to [a] larger audience that may also play a role in both
    the decisionmaking process and the implementation of that decision.” Dep’t of Transp. v.
    Public Citizen, 
    541 U.S. 752
    , 768 (2004) (quoting Robertson v. Methow Valley Citizens
    Council, 
    490 U.S. 332
    , 349 (1989)).

    No. 19-50178
    Land Office’s claim accrued—no later than December 27, 1990, when the
    Service’s decision to list the Warbler became final. See Davis Mountains Trans-
    Pecos Heritage Ass’n v. Fed. Aviation Admin., 116 F. App’x 3, 17 (5th Cir. 2004)
    (concluding that a NEPA claim accrued when an agency “failed to do something
    required by NEPA”). Consequently, to the extent that the General Land
    Office’s NEPA claim challenges the Service’s initial decision to list the Warbler,
    that claim is barred by § 2401(a).
    The General Land Office attempts to render its claims timely by framing
    them as ongoing failures to act and then invoking the continuing violation
    doctrine, but that attempt is unavailing. The continuing violation doctrine does
    not apply to claims based on discrete actions, 
    Doe, 853 F.3d at 802
    , or to
    “failures to act” that are properly characterized “as discrete events, not as
    ongoing, durational conditions.” Texas v. United States, 
    891 F.3d 553
    , 564 (5th
    Cir. 2018). Further, if “an agency is compelled by law to act within a certain
    time period” but fails to do so, that failure qualifies as a “discrete agency
    action.” Norton v. S. Utah Wilderness All., 
    542 U.S. 55
    , 65-66 (2004). As we
    have already described, the General Land Office’s claims challenging the
    Service’s initial decision to list the Warbler are based on alleged failures to
    take actions required by the ESA and NEPA before statutory deadlines.
    B.
    While we lack jurisdiction over the General Land Office’s untimely
    challenge to the Service’s decision to list the Warbler, we can consider the
    merits of the General Land Office’s NEPA claim to the extent that this claim
    challenges the Service’s 2016 decision to deny the delisting petition. The
    district court’s decision dismissing that claim under Rule 12(b)(6) is subject to
    de novo review. Ctr. for Biological Diversity, Inc. v. BP Am. Prod. Co., 
    704 F.3d 413
    , 421 (5th Cir. 2013). Because NEPA’s procedural requirements do not
    13
    Case: 19-50178      Document: 00515272659      Page: 14   Date Filed: 01/15/2020
    No. 19-50178
    apply to the Service’s listing decisions, we conclude that the district court’s
    decision was correct.
    NEPA does not require agencies to prepare an environmental impact
    statement if the agency’s discretion is constrained by law such that it could not
    consider the information that would be contained in such a statement as part
    of its decisionmaking process. Dep’t of Transp. v. Public Citizen, 
    541 U.S. 752
    ,
    769-70 (2004). This result flows from the fact that “inherent in NEPA and its
    implementing regulations is a ‘rule of reason,’ which ensures that agencies
    determine whether and to what extent to prepare an EIS based on the
    usefulness of any new potential information to the decisionmaking process.”
    
    Id. at 767.
    “It would not . . . satisfy NEPA’s ‘rule of reason’ to require an agency
    to prepare a full EIS due to the environmental impact of an action it could not
    refuse to perform.” 
    Id. at 769;
    see also 
    id. at 767
    (“Where the preparation of an
    EIS would serve ‘no purpose’ in light of NEPA’s regulatory scheme as a whole,
    no rule of reason worth that title would require an agency to prepare an EIS.”)
    The ESA prohibits the Service from considering the information that
    would be contained in an environmental impact statement when deciding
    whether to list or delist a species as endangered or threatened. The ESA
    carefully details the five biological factors that can render a species endangered
    or threatened, 16 U.S.C. § 1533(a)(1), and it requires decisions about whether
    a species is or is not endangered or threatened to be made “solely on the basis
    of the best scientific and commercial data available,” 
    id. § 1533(b)(1)(A).
    As the
    Sixth Circuit put it decades ago:
    [T]he statutory mandate of ESA prevents the [Service] from
    considering the environmental impact when listing a species as
    endangered or threatened. . . . The impact statement cannot insure
    the agency made an informed decision and considered
    environmental factors where the agency has no authority to
    consider environmental factors. As far as the determination to list
    14
    Case: 19-50178     Document: 00515272659     Page: 15    Date Filed: 01/15/2020
    No. 19-50178
    a species is concerned, preparing an impact statement is a waste
    of time.
    Pac. Legal Found. v. Andrus, 
    657 F.2d 829
    , 836 (6th Cir. 1981). Since the
    Service does not need to prepare environmental impact statements for its
    listing decisions, environmental assessments—which help agencies figure out
    whether they need to prepare environmental impact statements—are likewise
    unnecessary. Consequently, the Service did not violate NEPA or its
    implementing regulations when it declined to delist the Warbler, and the
    district court correctly granted the Service’s motion to dismiss.
    C.
    Although the Service’s decision to deny the delisting petition did not
    violate NEPA, that decision was arbitrary and capricious. We review the
    district court’s contrary conclusion de novo. Sabine River Auth. v. U.S. Dep’t of
    Interior, 
    951 F.2d 669
    , 679 (5th Cir. 1992). An agency decision is “arbitrary,
    capricious, an abuse of discretion, or otherwise not in accordance with law,” 5
    U.S.C. § 706(2)(A), if the agency applies an incorrect legal standard, see Koon
    v. United States, 
    518 U.S. 81
    , 100 (1996) (“A district court by definition abuses
    its discretion when it makes an error of law.”); see also Caring Hearts Personal
    Home Servs., Inc. v. Burwell, 
    824 F.3d 968
    , 977 (10th Cir. 2016) (Gorsuch, J.)
    (“[A]n agency decision that loses track of its own controlling regulations and
    applies the wrong rules in order to penalize private citizens can never stand.”);
    Humane Soc’y of the U.S. v. Pritzker, 
    75 F. Supp. 3d 1
    , 11 (D.D.C. 2014)
    (“NMFS acted arbitrarily and capriciously in applying an inappropriately-
    stringent evidentiary requirement at the 90-day stage.”).
    The Service was required to respond to the delisting petition by
    conducting a twelve-month review if the petition contained “substantial
    scientific or commercial information indicating that the petitioned action may
    be warranted.” 16 U.S.C. § 1533(b)(3)(A). Then-applicable regulations specified
    15
    Case: 19-50178    Document: 00515272659       Page: 16   Date Filed: 01/15/2020
    No. 19-50178
    that this standard required “that amount of information that would lead a
    reasonable person to believe that the measure proposed in the petition may be
    warranted.” 50 C.F.R. § 424.14(b)(1) (2014).
    The Service recited this standard, but a careful examination of its
    analysis shows that the Service applied an inappropriately heightened one.
    Specifically, to proceed to the twelve-month review stage, the Service required
    the delisting petition to contain information that the Service had not
    considered in its five-year review that was sufficient to refute that review’s
    conclusions. See Negative Ninety-Day 
    Finding, supra, at 2
    (“Much of this
    argument is based on Mathewson et al. (2012, p. 1,123) . . . . The Mathewson
    et al. (2012) study was considered by the Service and discussed in our most
    recent 5-year review for the warbler . . . .”); 
    id. at 3
    (“This and other pertinent
    information was evaluated in the 2014 5-year review where we recommended
    that the species remain listed as in danger of extinction throughout its range
    (Service 2014, p. 15).”); 
    id. at 5
    (“Information provided in the petition is refuted
    by the 2014 5-year review, in which we conclude . . . .”); 
    id. at 6
    (“The petition
    does not provide any new information indicating that predation is no longer a
    threat to the warbler.” (emphasis added)); 
    id. at 9
    (“There are additional
    threats that we evaluated and identified in the 2014 5-year review . . . . The
    petition did not present any information to address these threats.”); 
    id. at 10
    (“This and other pertinent information was evaluated in the 2014 5-year
    review.”); 
    id. (“No new
    information is presented that would suggest that the
    species was originally listed due to an error in information.” (emphasis added)).
    The Service thus based its decision to deny the delisting petition on an
    incorrect legal standard. Consequently, we conclude that the Service’s decision
    was arbitrary and capricious. We therefore vacate that decision and remand
    for the Service to evaluate the delisting petition under the correct legal
    standard. See Sw. Elec. Power Co. v. EPA, 
    920 F.3d 999
    , 1022 (5th Cir. 2019)
    16
    Case: 19-50178   Document: 00515272659     Page: 17   Date Filed: 01/15/2020
    No. 19-50178
    (vacating the portion of an agency rule found to be arbitrary and capricious
    and remanding to the agency for reconsideration).
    IV
    For the foregoing reasons, we AFFIRM the district court in part,
    REVERSE the district court in part, VACATE the Service’s decision denying
    the delisting petition, and REMAND to the Service for further proceedings.
