    At issue in this case is whether the Bureau of Land Management (BLM) is
    required to conduct an environmental analysis under the National Environmental
    Policy Act (NEPA), 
    42 U.S.C. § 4321
    , et seq., when it re-opens an area that it had
    temporarily closed to off-highway vehicles (OHVs) pursuant to its authority under
    
    43 C.F.R. § 8341.2
    (a). In 2006, the BLM closed a portion of the Factory Butte area in
    Utah to OHVs due to their adverse effects on the endangered Wright fishhook cactus.
    The BLM lifted that closure order in 2019 and re-opened the area to OHV use, but
    did not perform any kind of environmental analysis under NEPA before doing so.
    The Plaintiffs filed suit pursuant to 
    28 U.S.C. § 1331
    , alleging violations of NEPA
    and the Administrative Procedure Act (APA), 
    5 U.S.C. § 500
    , et seq. The Plaintiffs
    challenged the BLM’s decision to re-open, arguing that a NEPA analysis was
    required. The district court disagreed and dismissed their complaint for failure to
    state a claim upon which relief can be granted. The Plaintiffs now appeal, and
    exercising jurisdiction pursuant to 
    28 U.S.C. § 1291
    , we affirm.

    I
    A. Statutory and Regulatory Background
    The BLM manages public lands under the Federal Land Policy and Management
    Act (FLPMA), 
    43 U.S.C. § 1701
    , et seq. FLPMA directs the BLM to manage public
    lands “under principles of multiple use and sustained yield.” 
    Id.
     § 1732(a). “‘Multiple use
    management’ is a deceptively simple term that describes the enormously complicated
    task of striking a balance among the many competing uses to which land can be put . . . .”
    Utah Shared Access All. v. Carpenter, 
    463 F.3d 1125
    , 1128 (10th Cir. 2006)
    (quoting Norton v. S. Utah Wilderness All., 
    542 U.S. 55
    , 58 (2004)). To assist in the
    management of public lands, the BLM prepares comprehensive resource management
    plans (RMPs). 
    43 U.S.C. § 1712
    (a). As is relevant to this case, RMPs designate public
    lands as “either open, limited, or closed to off-road vehicles.” 
    43 C.F.R. § 8342.1
    .
    When developing an RMP, an important step for the BLM is the completion of an
    environmental analysis under NEPA. “NEPA requires all agencies that propose a ‘major
    federal action’ that significantly affects the quality of the environment to prepare an
    environmental impact statement (‘EIS’) that describes the environmental impact of the
    action[,] unavoidable adverse environmental effects[,] [and] alternatives to the action,”
    among other things. Carpenter, 
    463 F.3d at 1131
     (quotations omitted); 
    42 U.S.C. § 4332
    (2)(C). A “major [f]ederal action” is one “with effects that may be major and
    which are potentially subject to [f]ederal control and responsibility.” 
    40 C.F.R. § 1508.18
    3
    (2019). 1 The development of an RMP is a “major federal action,” and as such, the BLM
    is required to prepare an environmental analysis on the matter. 
    43 C.F.R. § 1601.0
    –6;
    State of Utah v. Babbitt, 
    137 F.3d 1193
    , 1214 (10th Cir. 1998). Amendments to an RMP
    likewise require environmental analysis under NEPA. 
    43 C.F.R. § 1610.5
    –5; Carpenter,
    
    463 F.3d at 1131
    . “If the impact of the major federal action on the environment is
    uncertain, the agency must prepare an environmental assessment (‘EA’) to determine
    whether the impact will be significant such that an EIS is required.” Carpenter, 
    463 F.3d at 1131
    . Once an RMP is finalized and approved, FLPMA directs the BLM to “manage
    the public lands . . . in accordance with the [RMP].” 
    43 U.S.C. § 1732
    (a).
    But this directive is not FLPMA’s only mandate. FLPMA also requires the BLM
    to “take any action necessary to prevent unnecessary or undue degradation of the lands.”
    
    Id.
     § 1732(b). Accordingly, in 1979 the BLM, following executive orders issued by
    Presidents Nixon and Carter regarding damage to public lands caused by OHVs,
    promulgated a regulation governing temporary closure of public lands to OHV use
    separate from the RMP process. That regulation reads in pertinent part:
    [W]here the authorized officer determines that off-road vehicles are causing
    or will cause considerable adverse effects upon soil, vegetation, wildlife,
    wildlife habitat, cultural resources, historical resources, threatened or
    endangered species, wilderness suitability, other authorized uses, or other
    resources, the authorized officer shall immediately close the areas affected
    1
    This version of the regulation was in effect in 2019 when the BLM lifted the
    temporary closure order that is at issue in this case. Accordingly, it is the relevant
    definition of “major federal action” for this case, since the recently promulgated
    regulation defining “major federal action,” which took effect September 14, 2020,
    does not operate retroactively. See Bowen v. Georgetown Univ. Hosp., 
    488 U.S. 204
    ,
    208 (1988); De Niz Robles v. Lynch, 
    803 F.3d 1165
    , 1172 (10th Cir. 2015).
    4
    to the type(s) of vehicle causing the adverse effect until the adverse effects
    are eliminated and measures implemented to prevent recurrence.
    
    43 C.F.R. § 8341.2
    (a).
    Section 8341.2(a) “creates a separate duty to close [public lands] without regard to
    the [land use] designation process.” Carpenter, 
    463 F.3d at 1130
    . Therefore, even if an
    RMP designates an area as open to OHV use, the BLM “shall immediately close” that
    area if it determines that OHV use is “causing or will cause considerable adverse effects.”
    
    43 C.F.R. § 8341.2
    (a). We have held that such temporary closure orders under
    § 8341.2(a) are not amendments to an RMP’s land use designations that require
    environmental analysis under NEPA. Carpenter, 
    463 F.3d at
    1135–37. 2 However, we
    have not previously addressed the question presented here: whether the BLM’s decision
    to lift a temporary closure order and return an area to its open designation requires an
    environmental analysis under NEPA.
    B. Factual Background
    The Factory Butte area, located on federal public lands in Wayne County, Utah, is
    home to the Wright fishhook cactus. The Wright fishhook cactus has been listed as an
    endangered plant species under the Endangered Species Act since 1979. The Factory
    2
    Our holding in Carpenter was based exclusively on our conclusion that a
    temporary closure order under § 8341.2(a) was not an amendment to an RMP. We did
    not address whether “the issuance of a closure order pursuant to 
    43 C.F.R. § 8341.2
    (a) constitutes either a ‘proposal’ or a ‘major Federal action’” under NEPA
    because the Plaintiffs did not clearly raise those arguments. Carpenter, 
    463 F.3d at
    1136 n.4 (10th Cir. 2006). At any rate, the Plaintiffs here do not take issue with
    Carpenter’s result: that a temporary closure order does not require environmental
    analysis.
    5
    Butte area is not only where the Wright fishhook cactus is located, but the area is also
    host to many visitors using cross-country OHVs like motorcycles, all-terrain vehicles,
    and four-wheel drive trucks.
    In 1982, the BLM approved the Henry Mountains Management Framework Plan 3
    for roughly 1.9 million acres of land, including the Factory Butte area. Despite OHV use
    in the area causing “unsightly scars” such that “undue and unnecessary degradation” may
    have been occurring, the 1982 Management Framework Plan designated the Factory
    Butte area as open for cross-country OHV use. Aplt. App. at 22–23.
    In 2006, a BLM survey of cacti species in the area indicated that OHV use was
    negatively impacting threatened and endangered species of cacti, specifically the Wright
    fishhook cactus. Based on this information, the BLM’s authorized officer “determined
    that OHV use in the area is causing or will cause adverse effects to threatened and
    endangered plant species.” Notice of Off-Highway Vehicle (OHV) Travel Restriction for
    Factory Butte Area, UT, 
    71 Fed. Reg. 55009
     (Sept. 20, 2006). The BLM accordingly
    invoked its authority under 
    43 C.F.R. § 8341.2
    (a) and closed 142,023 acres of the Factory
    Butte area to cross-country OHV use. Id.; Aplt. App. at 25. The closure order was to
    remain in effect until the conditions threatening the cacti species were sufficiently
    addressed or until the BLM’s Richfield Field Office completed its new RMP. The
    closure did not affect 2,600 acres within the Factory Butte area known as Swing Arm
    City.
    Before FLPMA and during the transition period after FLPMA’s passage,
    3
    RMPs were known as Management Framework Plans. See 
    43 C.F.R. § 1610.8
    .
    6
    In 2008, the BLM’s Richfield Field Office released a Proposed RMP and a Final
    Environmental Impact Statement (Final EIS). The Proposed RMP designated three
    cross-country OHV “play areas,” where cross-country OHV travel would be allowed:
    5,800 acres around Factory Butte, 4 2,600 acres in Swing Arm City, and 100 acres in
    Caineville Cove Inn. Notwithstanding this designation, the Proposed RMP explained that
    the 2006 temporary closure order of the Factory Butte and Caineville Cove Inn areas
    would remain in effect until the BLM signed a Record of Decision approving the RMP
    because OHVs around Factory Butte were still “causing . . . adverse effects on
    [threatened and endangered] plant species in the area.” Aplt. App. at 27. The Final and
    Approved 2008 RMP continued to designate the Factory Butte area as open to OHV use,
    but it did not lift the temporary closure order. Rather, consistent with § 8341.2(a), the
    closure order was to remain in effect until the BLM ensured that “infrastructure [was] in
    place and a monitoring program enacted to protect threatened and endangered cacti” and
    the temporary closure order was “formally rescinded by the authorized officer.” Id. at 82.
    Starting in 2009, the BLM conducted annual monitoring of the Wright fishhook
    cactus within the closed Factory Butte area. In 2010, the U.S. Fish and Wildlife Service
    4
    The Final and Approved 2008 RMP is unclear on the exact area around
    Factory Butte that is designated open. In some places, the RMP says the area
    encompasses 5,800 acres, Aplt. App. at 85, 86; in others, the RMP says 5,300 acres.
    Id. at 102, 103. The 2019 BLM press release announcing the lifting of the temporary
    closure order indicated that the area around Factory Butte was only 5,300 acres
    (resulting in a 5,400-acre re-opening when combined with the 100 acres in Caineville
    Cove Inn). It is therefore unclear whether 500 acres around Factory Butte remain
    designated open but temporarily closed or whether there was a technical oversight in
    the RMP and only 5,300 acres were ever designated as open.
    7
    issued a biological opinion predicting that the most likely impacts caused by opening the
    Factory Butte area would be indirect impacts from OHVs: increased airborne dust and
    particulates, changes in pollinator-plant interactions, and increased illegal OHV use
    leading to habitat fragmentation and degradation. The BLM continued its monitoring of
    the Wright fishhook cactus through 2018.
    In April 2019, the BLM submitted a memorandum to the U.S. Fish and Wildlife
    Service stating that the BLM had complied with the requirements of the 2010 biological
    opinion and additional conservation measures. The BLM sought the concurrence of the
    U.S. Fish and Wildlife Service in this assessment. The BLM further expressed its intent
    to move forward with rescinding the 2006 temporary closure order and opening the
    Factory Butte area to cross-country OHV use. The BLM then sent a follow-up
    memorandum requesting changes to the 2010 biological opinion and associated
    monitoring plan. Specifically, the BLM requested “new thresholds for OHV disturbance
    within [the] Wright fishhook cactus habitat,” changes to the “the point at which [the]
    BLM [wa]s required to reinitiate consultation with the [U.S.] Fish and Wildlife Service
    based on impacts to the endangered cactus,” and “modifications to [the BLM’s] Wright
    fishhook cactus monitoring obligations.” Id. at 28–29. Although the record is unclear on
    whether these proposed changes increased or decreased the level of protection of the
    Wright fishhook cactus, we can infer that the proposed changes corresponded with the
    minimum level of protection necessary to avoid jeopardizing the Wright fishhook cactus.
    On May 20, 2019, the U.S. Fish and Wildlife Service accepted the proposed changes and
    8
    concluded that opening the Factory Butte area to cross-country OHV use was not likely
    to jeopardize the Wright fishhook cactus.
    Two days later, the BLM issued a press release announcing that it was lifting the
    2006 temporary closure order and opening the play areas in “Factory Butte (5,300 acres)
    and Caineville Cove (100 acres)” to cross-country OHV use. Press Release, Bureau of
    Land Mgmt., Richfield Field Off., After 10 Years of Extensive Monitoring BLM Opens
    5,400 Acres to OHV Recreation (May 22, 2019), available at https://www.blm.gov/press-
    release/blm-opens-5400-acres-ohv. The BLM subsequently produced a three-page
    “Memo to File” documenting its decision. As is relevant here, the BLM did not conduct
    an environmental analysis under NEPA or provide the opportunity for public comment
    before lifting its closure order.
    II
    The Plaintiffs—Natural Resources Defense Council, Southern Utah Wilderness
    Alliance, and The Wilderness Society—filed a complaint in the United States District
    Court for the District of Utah for declaratory and injunctive relief against Defendant
    Joelle McCarthy, in her official capacity as the manager of the BLM Richfield Field
    Office, the BLM, and the U.S. Department of Interior (collectively, “the BLM”). The
    State of Utah later intervened as a Defendant. The Plaintiffs alleged that the BLM
    violated NEPA and the APA by failing to analyze the environmental consequences of its
    action to lift the temporary closure order and open the Factory Butte area to cross-country
    OHV use. The Plaintiffs requested that the court set aside the BLM’s decision to lift the
    9
    Factory Butte closure order and re-impose the closure order until the agency complied
    with NEPA.
    The BLM filed a motion to dismiss under Rule 12(b)(6) for failure to state a claim
    upon which relief can be granted. The BLM argued that the lifting of the temporary
    closure order and re-opening of the Factory Butte area to OHV use was a
    non-discretionary act required by law, and therefore NEPA does not apply.
    The district court agreed and granted the BLM’s motion to dismiss. Specifically,
    the district court reasoned that because the BLM’s decision to impose a temporary
    closure order under 
    43 C.F.R. § 8341.2
    (a) is non-discretionary under our decision in
    Carpenter, and therefore exempt from NEPA analysis, the decision to lift the temporary
    closure order “is also a nondiscretionary action of the BLM which is exempt from . . .
    NEPA.” Aplt. App. at 112. Pointing to the plain text of the regulation, the district court
    explained:
    Under § 8341.2(a), the BLM has authority to determine that OHV’s “are
    causing or will cause considerable adverse effects.” The BLM also has
    authority to determine that “the adverse effects have been eliminated and
    measures implemented to prevent recurrence.” But in both instances, once
    these determinations are made, the regulation mandates the BLM’s action.
    Id. (citations omitted).
    The district court further explained that its reading of the regulation complied with
    the overall public land management scheme under FLPMA. The district court noted that
    “[§] 8341.2(a) creates a separate duty to close [public lands] without regard” to an RMP’s
    designation of those lands as open to OHV use. Id. (quoting Carpenter, 
    463 F.3d at 1130
    ). Indeed, the district court reasoned, our decision in Carpenter exempting
    10
    temporary closure orders from NEPA analysis allows the BLM to quickly close an area
    under § 8341.2(a) and comply with FLPMA’s mandate to “take any action necessary to
    prevent unnecessary or undue degradation of the lands.” Id. at 113 (quoting Carpenter,
    
    463 F.3d at 1136
    ); see also 
    43 U.S.C. § 1732
    (b). In the district court’s view, likewise
    exempting the BLM’s re-opening of an area from NEPA analysis allows the RMP’s
    designation of that area to resume promptly, complying with FLPMA’s countervailing
    mandate to “manage the public lands . . . in accordance with the [RMP].” 
    Id.
     (quoting
    
    43 U.S.C. § 1732
    (a)). The district court thus concluded that the entire temporary closure
    process under § 8341.2(a)—both closing and opening—is a non-discretionary process
    that exists separately from the RMP and is therefore exempt from NEPA analysis. See id.
    at 114.
    The district court dismissed the Plaintiffs’ complaint with prejudice and the
    Plaintiffs timely appealed.
    III
    We review the district court’s grant of a Rule 12(b)(6) motion de novo. Barnett v.
    Hall, Estill, Hardwick, Gable, Golden & Nelson, P.C., 
    956 F.3d 1228
    , 1234 (10th Cir.
    2020). Although at this stage “we must accept all the well-pleaded allegations of the
    complaint as true and must construe them in the light most favorable to the plaintiff,”
    Thomas v. Kaven, 
    765 F.3d 1183
    , 1190 (10th Cir. 2014), the sufficiency of the Plaintiffs’
    factual allegations is not at issue in this case. This appeal presents a question of
    regulatory construction, which we review de novo. Bd. of Educ. of Gallup-McKinley
    Cnty. Schs. v. Native Am. Disability Law Ctr., Inc., 
    959 F.3d 1011
    , 1013 (10th Cir. 2020).
    11
    The related question of whether NEPA applies to the BLM’s lifting of a temporary
    closure order is also subject to de novo review. Citizens Against Rails-to-Trails v. Surface
    Transp. Bd., 
    267 F.3d 1144
    , 1150–51 (D.C. Cir. 2001) (“Because NEPA’s mandate is
    addressed to all federal agencies, the [agency]’s determination that NEPA is inapplicable
    . . . is not entitled to the deference that courts must accord to an agency’s interpretation of
    its governing statute.”).
    We note the Plaintiffs in this case did not challenge the 2008 RMP’s designation
    of the Factory Butte area as open to OHV use. Nor do they challenge at this juncture the
    merits of the BLM’s decision to lift the temporary closure order, i.e., whether adequate
    measures were in place to protect threatened and endangered cacti. The Plaintiffs argue
    only that the BLM was required to perform environmental analysis under NEPA before
    lifting the temporary closure order of the Factory Butte area.
    Environmental analysis under NEPA is subject to a “rule of reason,” such that it is
    only required when it would provide information that influences an agency’s
    decision-making process involving a “major federal action.” Dep’t of Transp. v. Pub.
    Citizen, 
    541 U.S. 752
    , 767 (2004); see also Sierra Club v. Hodel, 
    848 F.2d 1068
    , 1089
    (10th Cir. 1988) (explaining that “the distinguishing feature” of a “major federal action”
    is an agency’s “ability to influence or control the outcome in material respects”),
    overruled on other grounds by Vill. of Los Ranchos De Albuquerque v. Marsh, 
    956 F.2d 970
     (10th Cir. 1992) (en banc). Accordingly, NEPA applies only where an agency action
    is discretionary. But where an agency action is non-discretionary and mandated by law,
    environmental analysis “would serve no purpose,” and NEPA does not apply. Pub.
    12
    Citizen, 
    541 U.S. at 767
     (quotations omitted); accord Sac & Fox Nation of Mo. v. Norton,
    
    240 F.3d 1250
    , 1262–63 (10th Cir. 2001) (collecting cases holding that “NEPA
    compliance is unnecessary where the agency action at issue involves little or no
    discretion on the part of the agency” and concluding that NEPA analysis was not required
    in the case at hand and indeed “would have been pointless” because the federal agency
    had no discretion and was mandated by statute to take a certain action). As discussed
    above, our decision in Carpenter held that the decision to temporarily close public lands
    under 
    43 C.F.R. § 8341.2
    (a) is non-discretionary. Carpenter, 
    463 F.3d at 1130
     (“[S]uch
    closures are nondiscretionary: the BLM ‘shall immediately close the areas affected to the
    type(s) of vehicle causing the adverse effect until the adverse effects are eliminated and
    measures implemented to prevent recurrence.’” (quoting 
    43 C.F.R. § 8341.2
    (a))
    (emphasis omitted). As a result, a temporary closure order is exempt from NEPA. See
    Sac & Fox Nation of Mo., 
    240 F.3d at
    1262–63.
    The issue in this case thus boils down to whether the BLM’s decision to lift a
    temporary closure order under 
    43 C.F.R. § 8341.2
    (a) is likewise a non-discretionary
    action, such that environmental analysis under NEPA is not required. Invoking the text of
    the regulation and its alleged protective purpose in the larger statutory scheme, the
    Plaintiffs argue (1) the BLM retains discretion to lift the temporary closure order even
    after it determines the “adverse effects are eliminated and measures implemented to
    prevent recurrence,” and (2) the BLM’s determination that “the adverse effects are
    eliminated and measures implemented to prevent recurrence” is also itself discretionary.
    In either case, the Plaintiffs contend, environmental analysis under NEPA is required. In
    13
    contrast, the BLM says the regulation is symmetrical. The BLM argues NEPA analysis is
    not required at any point because the agency has no discretion to temporarily close an
    area, and no discretion to keep the closure order in place once the requisite determination
    has been made. Additionally, the determination that “the adverse effects are eliminated
    and measures implemented to prevent recurrence” is not an open-ended act of discretion;
    rather, just like the initial determination that OHVs are “causing or will cause adverse
    effects” in the first place, it is a judgment triggering mandatory action under the
    regulation. We believe the BLM presents the better reading of the regulation and
    conclude that the lifting of the temporary closure order is non-discretionary. As a result,
    the BLM is not required under NEPA to conduct further environmental analysis before
    lifting a temporary closure order where the relevant RMP designates the area as open to
    OHV use.
    A. The Lifting of the Temporary Closure Order is Non-Discretionary
    When interpreting regulations, “we begin our analysis by examining the plain
    language of the text of the regulation, giving the words their ordinary meaning.” Bd. of
    Educ. of Gallup-McKinley Cnty. Schs., 959 F.3d at 1013. “If the meaning of the text is
    clear, our endeavor is at an end, and we must enforce the regulation in accordance with
    its plain meaning.” Id.
    The relevant part of the temporary closure regulation reads:
    [W]here the authorized officer determines that off-road vehicles are causing
    or will cause considerable adverse effects . . . the authorized officer shall
    immediately close the areas affected to the type(s) of vehicle causing the
    adverse effect until the adverse effects are eliminated and measures
    implemented to prevent recurrence.
    14
    
    43 C.F.R. § 8341.2
    (a).
    The Plaintiffs say the mandatory “shall” applies only to the closure order and that
    there is no countervailing mandate to re-open closed lands to OHV use, since the re-
    opening clause is introduced by the word “until.” In their view, the word “‘until’ signals
    the conditions that must be satisfied prior to lifting a travel closure, not an event upon
    which a closure lifts automatically.” Aplt. Br. at 18. But this goes against an ordinary
    reading of the regulation, specifically of the word “until.” “Until” can be “used as a
    function word to indicate continuance (as of an action or condition) to a specified time,”
    or as a conjunction meaning “up to the time that.” Merriam-Webster Dictionary,
    https://www.merriam-webster.com/dictionary/until (last visited March 24, 2021). In
    either sense, the plain meaning of “until” is that the activity or situation that precedes the
    word ends at the specified time that follows. The examples used by the Plaintiffs’ cited
    dictionary bear this out: if a person “stayed until morning,” that means they left in the
    morning, not that they could leave in the morning. 
    Id.
     Likewise, if “play continued until it
    got dark,” then play stopped at dark; it did not continue into the night. 
    Id.
     Applying that
    understanding here, § 8341.2(a) requires the BLM to lift a temporary closure order once
    it finds that “the adverse effects are eliminated and measures implemented to prevent
    recurrence.” The regulation plainly does not allow the BLM to maintain the temporary
    closure order after it has made the requisite finding.
    15
    B. The Determination Triggering the Lifting of the Temporary Closure Order is
    Also Non-Discretionary
    The Plaintiffs alternatively argue that the BLM’s determination that “the
    adverse effects are eliminated and measures implemented to prevent recurrence,”
    
    43 C.F.R. § 8341.2
    (a), is itself a discretionary act requiring NEPA analysis. Although
    this presents a closer question than the Plaintiffs’ first argument, we are ultimately
    unpersuaded due to instructive Supreme Court precedent, out of circuit authority, and
    our own decision in Carpenter.
    In National Association of Home Builders v. Defenders of Wildlife, 
    551 U.S. 644
    , 650–51 (2007), the Supreme Court interpreted a provision of the Clean Water
    Act providing that the EPA “shall” approve a transfer of its pollution discharge
    permitting authority to state officials if the state met nine specified criteria. 5 The
    To transfer permitting authority under the statute, the EPA had to determine
    5
    whether a state had the ability:
    (1) to issue fixed-term permits that apply and ensure compliance with
    the CWA’s substantive requirements and which are revocable for
    cause; (2) to inspect, monitor, and enter facilities and to require
    reports to the extent required by the CWA; (3) to provide for public
    notice and public hearings; (4) to ensure that the EPA receives
    notice of each permit application; (5) to ensure that any other State
    whose waters may be affected by the issuance of a permit may
    submit written recommendations and that written reasons be
    provided if such recommendations are not accepted; (6) to ensure
    that no permit is issued if the Army Corps of Engineers concludes
    that it would substantially impair the anchoring and navigation of
    navigable waters; (7) to abate violations of permits or the permit
    program, including through civil and criminal penalties; (8) to
    ensure that any permit for a discharge from a publicly owned
    treatment works includes conditions requiring the identification of
    the type and volume of certain pollutants; and (9) to ensure that any
    16
    specific issue was whether the Endangered Species Act’s (ESA) requirement that
    federal agencies consult with environmental agencies before taking any action that
    may jeopardize an endangered or threatened species—which, importantly, has been
    interpreted similarly to the environmental analysis requirement under NEPA, see 
    id.
    at 667–68—added a tenth criteria before the EPA could transfer permitting authority
    to a state. 
    Id. at 662
    . Concluding that the later-enacted ESA did not amend or repeal
    by implication the Clean Water Act, the Supreme Court held that consultation under
    the ESA was not required. The Court reasoned that the provision of the Clean Water
    Act “does not just set forth minimum requirements for the transfer of permitting
    authority; it affirmatively mandates that the transfer ‘shall’ be approved if the
    specified criteria are met.” 
    Id. at 663
     (emphasis omitted). The Court then rejected the
    argument “that the EPA’s decision to authorize a transfer is not entirely mechanical
    [and] that it involves some exercise of judgment as to whether a State has met the
    criteria set forth in [the statute].” 
    Id. at 671
    . The Court acknowledged that “the EPA
    may exercise some judgment in determining whether” a state had met the listed
    statutory criteria, but concluded that “the statute clearly does not grant [the EPA] the
    discretion to add another entirely separate prerequisite to that list.” 
    Id.
     Therefore,
    consultation under the ESA was not required.

    with certain of the CWA’s substantive provisions.

    33 U.S.C. § 1342
    (b)(1)–(9)).
    17
    The Sixth Circuit recently expanded on this seemingly metaphysical
    distinction between judgment and discretion in National Wildlife Federation v.
    Secretary of the United States Department of Transportation, 
    960 F.3d 872
     (6th Cir.
    2020). In that case, the Sixth Circuit explained that “[t]he clearest case of ‘discretion’
    is when an agency doesn’t have to act—for instance, if a statute says ‘may’ rather
    than ‘must’ or ‘shall.’” 
    Id. at 876
    . The Sixth Circuit further explained that “even
    mandatory actions . . . [may] be ‘discretionary’ under the Endangered Species Act
    (and related statutes) when the statutory criteria are so open-ended that they leave the
    agency significant flexibility on when or how to act.” 
    Id.
     (emphasis in original). But
    “this does not mean that any amount of open-endedness makes a decision
    ‘discretionary.’” 
    Id.
     at 876–77 (emphasis omitted). An “agency action need not be
    ‘entirely mechanical’ for the agency to still be exercising only ‘judgment,’ not
    ‘discretion.’” 
    Id. at 876
     (quoting Home Builders, 
    551 U.S. at 671
    ). Thus, under the
    Sixth Circuit’s view of the Supreme Court’s decision in Home Builders, if an “agency
    is required by [law]” to take a certain action once specified “triggering events have
    occurred,” the action is not discretionary, even though the agency may exercise some
    judgment in determining whether the “triggering events have occurred.” 
    Id.
    (quotations omitted). Put simply, “[d]iscretion and judgment are not the same thing.”
    Id. at 874. Only discretionary acts require consultation under the ESA or analysis
    under NEPA. Id. at 875, 879. Acts of judgment do not.
    Applying that distinction to a different provision of the Clean Water Act than
    the one at issue in Home Builders, the divided panel in National Wildlife Federation
    18
    held that the reasoning of Home Builders controlled. Once the relevant agency
    determined, in its judgment, that an operator of an oil pipeline demonstrated that it
    met six enumerated statutory criteria to address the risk of a potential oil spill, the
    agency was required to approve the oil pipeline’s response plan under the Clean
    Water Act. Id. at 877. 6 The agency was therefore not required to consult with other
    agencies under ESA or conduct environmental analysis under NEPA before
    approving these plans. Id. at 879, 880. The dissent concluded otherwise, believing
    that certain statutory criteria referring to a pipeline operator’s ability to remove
    discharge to the “maximum extent practicable” amounted to “an amorphous, moving
    6
    The plans had to satisfy the following criteria in the judgment of the
    agency:
    (i) be consistent with the requirements of the National Contingency Plan
    and Area Contingency Plans;
    (ii) identify the qualified individual having full authority to implement
    removal actions, and require immediate communications between that
    individual and the appropriate Federal official and the persons providing
    personnel and equipment pursuant to clause (iii);
    (iii) identify, and ensure by contract or other means approved by the
    President the availability of, private personnel and equipment necessary
    to remove to the maximum extent practicable a worst case discharge
    (including a discharge resulting from fire or explosion), and to mitigate
    or prevent a substantial threat of such a discharge;
    (iv) describe the training, equipment testing, periodic unannounced
    drills, and response actions of persons on the vessel or at the facility, to
    be carried out under the plan to ensure the safety of the vessel or facility
    and to mitigate or prevent the discharge, or the substantial threat of a
    discharge;
    (v) be updated periodically; and
    (vi) be resubmitted for approval of each significant change.

    target.” 
    Id.
     at 881–82 (Merritt, J., dissenting). In the dissent’s reading, the decision
    of whether that requirement had been met “involve[d] expertise, discretion, and
    judgment.” 
    Id. at 882
     (“The agency does not simply check the box for a ‘triggering
    event’ like the agency in Home Builders.”); Alaska Wilderness League v. Jewell,
    
    811 F.3d 1111
    , 1116 (9th Cir. 2015) (Gould, J., dissenting from denial of rehearing
    en banc) (reaching the same conclusion).
    Relying upon the above analysis from Home Builders and National Wildlife
    Federation, we conclude the BLM’s determination of whether “the adverse effects
    are eliminated and measures implemented to prevent recurrence” more closely
    resembles judgment than it does discretion. Accordingly, when that determination is
    made, the BLM need not conduct environmental analysis before lifting a temporary
    closure order. As the Sixth Circuit noted, the Supreme Court’s decision in “Home
    Builders makes clear that agency action need not be ‘entirely mechanical’ for the
    agency to still be exercising only ‘judgment,’ not ‘discretion.’” Nat’l Wildlife Fed’n,
    960 F.3d at 876 (quoting Home Builders, 
    551 U.S. at 671
    ).
    The Plaintiffs nevertheless contend that Home Builders and National Wildlife
    Federation are distinguishable because, in their view, those cases merely involved an
    evaluative judgment of whether another party had satisfied enumerated statutory
    criteria. This case is different, the Plaintiffs urge, because the “BLM’s role is not
    simply evaluative: the agency must itself formulate and implement protective
    measures before lifting a closure,” Aplt. Reply Br. at 8, which are discretionary acts
    that “form an inseparable part of the agency’s ultimate decision.” Id. at 15. But even
    20
    accepting that the BLM must itself formulate and implement protective measures,
    that does not make the subsequent decision to lift a temporary closure order
    discretionary.
    Indeed, we believe the examples of discretion relied upon by the Plaintiffs are
    quite different from the situation here. This is not a case where the criteria “are so
    open-ended that they leave the agency significant flexibility on when or how to act.”
    Nat’l Wildlife Fed’n, 960 F.3d at 876 (emphasis in original). Section 8341.2(a) does
    not charge the BLM “with developing . . . criteria” for when or how to lift a
    temporary closure order. Fla. Key Deer v. Paulison, 
    522 F.3d 1133
    , 1142 (11th Cir.
    2008) (concluding that consultation under ESA was required because the statutory
    scheme where FEMA managed its own flood insurance program “b[ore] little
    resemblance to the scheme in [Home Builders], where no discretion was found”);
    Stand Up for Cal. v. U.S. Dep’t of the Interior, 
    959 F.3d 1154
    , 1164 (9th Cir. 2020)
    (holding that the Department of the Interior retained discretion for NEPA purposes
    when formulating criteria to allow tribal gaming). Nor does the regulation instruct the
    BLM to consider criteria as vague and wide-ranging as “the public convenience and
    necessity.” Sierra Club v. Fed. Energy Regulatory Comm’n, 
    867 F.3d 1357
    , 1373
    (D.C. Cir. 2017) (concluding agency was required to prepare EIS when evaluating
    applications to construct and operate interstate pipelines). The BLM does not have
    “discretion to impose terms and conditions” on its decision to lift a temporary closure
    order. RESTORE: The North Woods v. U.S. Dep’t of Agric., 
    968 F. Supp. 168
    , 175
    (D. Vt. 1997) (holding that NEPA applied to a land exchange because the Forest
    21
    Service possessed “discretion to impose terms and conditions on the transaction and
    to approve or disapprove the transaction based on the acceptability of the lands to be
    acquired”). And as discussed above, this is plainly not a case where the agency was
    “authorized, but not required, to make” a certain decision, and therefore possessed
    total discretion to act. Friends of Columbia Gorge, Inc. v. U.S. Forest Serv., 
    546 F. Supp. 2d 1088
    , 1102 (D. Or. 2008) (holding that NEPA analysis was required).
    Unlike the situations described, an environmental analysis here would not
    influence whether the BLM lifts a temporary closure order. Section 8341.2(a)
    mandates lifting a temporary closure order when the BLM, in its judgment, makes the
    requisite finding that “the adverse effects are eliminated and measures implemented
    to prevent recurrence.” An environmental analysis under NEPA is not required where
    an agency action is mandated by law, and the environmental analysis “would serve
    no purpose.” Pub. Citizen, 
    541 U.S. at 767
     (quotations omitted). The relevant EIS
    was prepared in creating the 2008 RMP. The BLM’s mandatory decision to lift the
    temporary closure order does not trigger the need for a new EIS.
    Additionally, our reading of the regulation is guided by how we have
    interpreted the BLM’s determination to close an area to OHV use in the first place.
    Carpenter held, and the parties do not dispute, that a temporary closure is
    non-discretionary and NEPA analysis is not required even though the BLM must first
    determine that OHV use is “causing or will cause considerable adverse effects.”
    Carpenter, 
    463 F.3d at 1130
    . We conclude the determination to re-open—that “the
    adverse effects are eliminated and measures implemented to prevent recurrence”—
    22
    should be treated the same way. In other words, if the determination triggering the
    closure order is not discretionary, then neither is the determination triggering the
    re-opening. We therefore disagree with the Plaintiffs’ asymmetrical reading that
    § 8341.2(a) operates as a one-way ratchet where the BLM “exercise[s] judgment
    when implementing a closure order, [but] exercises discretion when lifting one.”
    Aplt. Reply Br. at 16 (emphases omitted).
    As further support, our reading of the regulation makes sense within the larger
    statutory and regulatory scheme. Section 8341.2(a) serves as a mechanism to
    temporarily close public lands. The closure is exempt from NEPA analysis to allow
    the agency to act quickly and “timely comply with its statutory mandate [under
    FLPMA] to ‘take any action necessary to prevent unnecessary or undue degradation
    of the lands.’” Carpenter, 
    463 F.3d at 1136
     (quoting 
    43 U.S.C. § 1732
    (b)). Likewise
    exempting the re-opening from NEPA analysis enables the BLM to timely comply
    with its countervailing statutory mandate under FLPMA to “manage the public lands
    . . . in accordance with the [RMP],” 
    43 U.S.C. § 1732
    (a), which, in this case,
    designated the Factory Butte area as open to cross-country OHV use.
    In contrast, the Plaintiffs’ interpretation of the regulatory scheme is untenable.
    In their view, the BLM’s statutory duty to “prevent unnecessary or undue degradation
    of the lands,” 
    id.
     § 1732(b), trumps all. Under their theory, the closure order is
    appropriately exempt from NEPA analysis to take urgent action to protect
    endangered species, but “there is no symmetrical urgency to reintroduce OHV use to
    a closed area,” making an exemption from NEPA analysis for that decision
    23
    inappropriate. Aplt. Br. at 29. But we believe reading § 8341.2(a) this way transforms
    it into an all-consuming provision that would allow the BLM to maintain a temporary
    closure order indefinitely, even after the agency makes the requisite determination
    triggering a re-opening and despite an area’s open designation under the relevant
    RMP. We have already rejected this position as contravening the text and structure of
    the regulation. But it also cuts against the apparent purpose of § 8341.2(a) as a
    mechanism for temporary closure orders. And it subordinates the RMP, which serves
    as the backdrop for the entire land management scheme under FLPMA. We believe
    our reading of the regulation, which accommodates both temporary closure orders
    and an RMP’s open designation, harmonizes FLPMA’s multiple mandates and
    “strik[es] a balance among the many competing uses to which land can be put . . . .”
    Carpenter, 
    463 F.3d at 1128
    .
    Finally, the factual circumstances highlighted by the Plaintiffs to argue that the
    BLM believed it had discretion are largely irrelevant to this purely legal question.
    That the 2008 RMP contemplated keeping the closure order in place until certain
    conditions were met merely comports with the requirements of § 8341.2(a). That the
    2008 RMP also indicated the BLM may choose to revise the Factory Butte area’s
    open designation in the future did not prevent the agency from lifting the closure
    order in 2019, nor did it constrain the agency in maintaining the open designation.
    And that the BLM consulted with the U.S. Fish and Wildlife Service on whether it
    had met the requirements of the Service’s 2010 biological opinion (presumably in
    24
    accordance with the ESA) does not mean that the BLM was required to conduct
    environmental analysis under NEPA as a matter of law.
    In short, the regulation’s text and place in the overall land management
    scheme, our decision in Carpenter, as well as instructive Supreme Court precedent
    and out of circuit guidance dictate the result here: where the relevant RMP designates
    an area as open to OHV use, lifting a temporary closure order of that area under
    
    43 C.F.R. § 8341.2
    (a) is non-discretionary and does not require NEPA analysis.
    IV
    For those reasons, we AFFIRM the district court’s dismissal of the Plaintiffs’
    complaint.
