    III. CONCLUSION
    EDWARDS, Senior Circuit Judge: This is a weighty case,
    involving numerous claims concerning environmental hazards
    at three sites on Navajo land near Tuba City, Arizona. The
    locations in dispute are (1) the Tuba City Uranium Processing
    Mill Site (“Mill”), which was the site of a Cold War mining
    operation that left behind a radioactive byproduct known as
    mill tailings; (2) the Tuba City Open Dump (“Dump”), a
    federal waste facility located on both Hopi and Navajo land
    that was operated by the United States Bureau of Indian
    Affairs (“BIA”) until 1997; and (3) the Highway 160 Dump
    Site (“Highway 160 Site”), which is situated near the Mill and
    has also been used as a dump.
    4
    The action giving rise to this appeal was initiated in 2007
    by Appellant El Paso Natural Gas Company (“El Paso”), the
    successor-in-interest to the corporation that mined uranium at
    the Mill. El Paso filed a complaint in District Court against
    the United States and various federal agencies and officials
    raising claims under two statutes: the Uranium Mill Tailings
    Radiation Control Act of 1978 (“Mill Tailings Act”), 
    42 U.S.C. §§ 7901-7942
    , and the Solid Waste Disposal Act,
    which is commonly referred to as the Resource Conservation
    and Recovery Act of 1976 (“RCRA”), 
    42 U.S.C. §§ 6901
    -
    6992k. Appellant Navajo Nation (“Tribe” or “Nation”)
    intervened and asserted parallel claims under the Mill Tailings
    Act and RCRA, as well as additional claims against the
    Government.
    In 2009, the District Court dismissed El Paso’s Mill
    Tailings Act claim without discovery and certified its ruling
    for interlocutory appeal. El Paso Natural Gas Co. v. United
    States (El Paso I), 
    605 F. Supp. 2d 224
     (D.D.C. 2009). This
    court affirmed the judgment of the District Court. El Paso
    Natural Gas Co. v. United States (El Paso II), 
    632 F.3d 1272
    (D.C. Cir. 2011).
    The District Court then dismissed the balance of
    Appellants’ claims in two memorandum opinions. The trial
    court first dismissed all of the Tribe’s claims, except those
    arising under RCRA. El Paso Natural Gas Co. v. United
    States (El Paso III), 
    774 F. Supp. 2d 40
     (D.D.C. 2011). The
    trial court next dismissed all of Appellants’ RCRA claims
    relating to the Dump for want of jurisdiction due to an
    administrative settlement between the BIA and the United
    States Environmental Protection Agency (“EPA”) that was
    formalized three years after the start of litigation. The District
    Court also dismissed the RCRA claims relating to the
    Highway 160 Site as moot. El Paso Natural Gas Co. v.
    5
    United States (El Paso IV), 
    847 F. Supp. 2d 111
     (D.D.C.
    2012). An order accompanying the decision denied a motion
    for discovery and dismissed the RCRA claims regarding the
    Dump and the Highway 160 Site with prejudice. These
    consolidated appeals followed.
    Given the number of statutes, claims, and locations at
    issue, we have summarized below the issues on appeal and
    our holdings with respect to each question before the court.
    SUMMARY
    RCRA Claims Relating to the Dump. The District Court
    dismissed these claims after EPA and the BIA entered into
    administrative settlement in 2010 under § 104 of the
    Comprehensive Environmental Response, Compensation, and
    Liability Act of 1980 (“CERCLA”), 
    42 U.S.C. §§ 9601-9675
    .
    The District Court held that this agreement triggered the
    jurisdictional bar in CERCLA § 113(h), which forecloses
    courts from hearing “challenges to removal or remedial action
    selected under [CERCLA § 104].” El Paso IV, 847 F. Supp.
    2d at 116-23 (citing 
    42 U.S.C. § 9613
    (h)). Challenging this
    ruling on four fronts, Appellants argue (1) that the
    Government lacked CERCLA § 104 authority because the
    waste at the Dump was naturally occurring; (2) that the
    Administrative Settlement cannot trigger § 113(h) because the
    settlement lacks an objective indicator of when, if ever,
    remediation will occur; (3) that their RCRA claims cannot be
    “challenges” under § 113(h) because they were filed before
    the CERCLA response action; and (4) that their claims are
    also not “challenges” because the enforcement of 40 C.F.R.
    Part 258 landfill regulations will neither delay nor affect the
    CERCLA response action. In light of Appellants’ own
    pleadings and the clear, if troubling, sweep of § 113(h), we
    6
    are obliged to affirm the dismissal of the RCRA claims
    related to the Dump.
    The District Court’s Dismissal of Appellants’ RCRA
    Claims as to the Dump “With Prejudice.” Appellants argue
    that, even if their RCRA claims must be dismissed pursuant to
    CERCLA § 113(h), the dismissal should have been without
    prejudice. We agree. We therefore reverse the dismissal “with
    prejudice” of Appellants’ RCRA claims that relate to the
    Dump and remand with instructions to the District Court to
    enter judgment against Appellants “without prejudice.”
    RCRA Claims Relating to the Highway 160 Site. The
    District Court dismissed the Tribe’s RCRA claim as moot
    because Congress authorized and appropriated funds for a
    cleanup at the site in 2009, and because the Tribe assumed
    responsibility for the cleanup and agreed to a release of
    liability. El Paso IV, 847 F. Supp. 2d at 123-24. It then
    concluded that El Paso did not have standing to pursue a
    RCRA claim independent of the Tribe. Id. at 124. Appellants
    argue that the scope of the waiver is much narrower than the
    District Court thought and does not reach groundwater
    remediation, which could be the relief obtained under RCRA.
    We agree with the Tribe that its RCRA claims at the Highway
    160 Site are not moot. We therefore vacate the District
    Court’s dismissal of Appellants’ RCRA claims as to the
    Highway 160 Site and remand the case so that these claims
    can be considered on the merits. Because we conclude that the
    Tribe’s RCRA claims at the Highway 160 Site are not moot,
    we need not consider whether El Paso has standing.
    The Government’s Contingent RCRA Counterclaim.
    The Government filed a counterclaim against El Paso under
    RCRA. The District Court dismissed the counterclaim without
    prejudice. El Paso argues that the dismissal should have been
    7
    with prejudice. We disagree and affirm the judgment of the
    District Court.
    The Tribe’s Mill Tailings Act Claims. The Tribe brought
    two claims under the Mill Tailings Act and its associated EPA
    regulations. See 
    42 U.S.C. §§ 7901-7942
    ; 40 C.F.R. Part 192.
    The District Court granted the Government’s Rule 12(b)(1)
    motion to dismiss because it thought the Mill Tailings Act
    precludes judicial review of claims that fall within the scope
    of the mandatory waiver in § 7915(a)(1). El Paso III, 
    774 F. Supp. 2d at 52
    . This conclusion was incorrect because the
    Mill Tailings Act does not preclude review of all claims under
    the Administrative Procedure Act (“APA”). We nevertheless
    affirm the dismissal on other grounds. The terms of the
    waiver executed by the Tribe effectively foreclose its Third
    Claim for Relief. And the Tribe’s Fourth Claim for Relief
    fails to state a cause of action under the APA.
    The Tribe’s Remaining Statutory Claims. The Tribe also
    sued under the American Indian Agricultural Resource
    Management Act (“Indian Agricultural Act”), 
    25 U.S.C. §§ 3701-3746
    , and the Indian Lands Open Dump Cleanup Act
    of 1994 (“Indian Dump Cleanup Act”), 
    25 U.S.C. §§ 3901
    -
    3908. We analyze these claims together because they present
    the same questions on appeal: namely, whether the statutes
    create private rights of action, and, if not, whether the Nation
    has adequately alleged an APA claim based on the
    Government’s failure to act. With respect to the Indian
    Agricultural Act, the Tribe conceded in its reply brief that the
    Act contains no private right to sue; we also find that the
    Tribe failed to plead a claim that is cognizable under the
    APA. We reach the same conclusions with respect to the
    Nation’s claim under the Indian Dump Cleanup Act. The
    statute creates agency obligations, but it does not focus on the
    rights of protected parties. Therefore, no right of action can be
    8
    implied in the Act. And the Tribe’s claim raises no viable
    action under the APA because it does not allege that the
    Government failed to act with respect to some discrete duty
    that was legally required.
    The Tribe’s Breach of Trust Claim. The Tribe cites
    several statutes in support of its claim that the Government
    breached fiduciary duties owed to the Nation. In particular,
    the Tribe relies on 25 U.S.C. § 640d-9(a), which provides that
    designated lands “shall be held in trust by the United States
    exclusively for the Navajo Tribe and as part of the Navajo
    Reservation.” The Tribe argues that this statute, in tandem
    with the Government’s actual control of the trust corpus (i.e.,
    the land at the Mill, Dump, and Highway 160 Site), creates a
    trust relationship and a concomitant cause of action for breach
    of trust. We disagree. Indeed, the Supreme Court, in a
    decision not cited by the parties, rejected the very argument
    now pressed by the Tribe. We also conclude that the Tribe’s
    argument is contrary to the principles articulated by the
    Supreme Court in Indian Tucker Act cases. Moreover, we are
    unconvinced by the Tribe’s remaining argument that other
    statutes – including many of the ones that form the basis for
    its other claims – establish a viable action here for breach of
    trust. Therefore, we hold that none of the cited statutes creates
    a cause of action for breach of trust.
    I.   BACKGROUND
    The three locations that are the subject of this suit are
    located on or near the border between the Hopi and Navajo
    reservations, near Tuba City, Arizona.
    9
    A. The Mill
    From 1956 to 1966, Rare Metals Corporation, the
    predecessor-in-interest to Appellant El Paso, mined
    approximately 800,000 tons of uranium at the Mill under a
    contract pursuant to a federal government nuclear weapons
    program. Uranium mining produces a sandy, radioactive
    byproduct called “tailings.” Until the 1970s, there was little
    recognition that tailings were hazardous. They were often left
    at mining sites, thus creating a serious threat to public health.
    In 1978, Congress sought to address the tailings problem
    by enacting the Mill Tailings Act. 
    42 U.S.C. § 7901
    (b)(2).
    The Act provides for a program to assess and remediate
    inactive mills sites. It establishes the United States
    Department of Energy (“DOE”) as the administering agency
    and requires it to designate inactive uranium mill sites for
    remediation “at or near” twenty locations enumerated in
    § 7912(a), including Tuba City, Arizona. Consistent with
    these provisions, the Mill was designated as a “processing
    site” to be remediated. The Act further directs EPA to
    promulgate standards to govern the cleanups at the designated
    tailings sites, id. § 7918, which EPA did a few years later, see
    40 C.F.R. Part 192.
    In 1985, before any remedial action at the Mill began, the
    DOE entered into a cooperative agreement with the Navajo
    and Hopi Tribes, on whose land the Mill sits. A cooperative
    agreement is a compulsory component of the Mill Tailings
    Act, which directs that the “Secretary shall, to the greatest
    extent practicable, enter into such agreements.” 
    42 U.S.C. § 7915
    (a). The Act requires that cooperative agreements
    contain liability waivers, 
    id.
     § 7915(a)(1), pursuant to which
    the Navajo and Hopi Tribes consented in 1985 to release the
    United States of “any liability or claim . . . arising out of the
    10
    performance of any remedial action on such millsite, vicinity
    property or depository site.” Coop. Agreement Between the
    United States Dep’t of Energy, the Navajo Tribe of Indians &
    the Hopi Tribe of Indians (“Coop. Agreement”) at 17-18,
    reprinted in Joint Appendix (“J.A.”) 214-15.
    A remedial action plan was then formulated. See App’x B
    to Coop. Agreement, reprinted in J.A. 237-70. The plan,
    which was agreed to by the Navajo and Hopi, included a
    stabilization-in-place strategy, whereby 1.4 million cubic
    yards of tailings were collected in a pile and then covered in a
    disposal cell onsite. The cover of the cell comprised a “radon
    barrier” consisting of compacted sand, topped by a layer of
    bedding, and then a layer of rock (riprap, to be precise)
    designed to protect the radon barrier from erosion. Id. at 43,
    reprinted in J.A. 262. The surface cleanup began in 1988 and
    was completed by 1990. A disposal cell spanning fifty acres
    now stands on the site. In addition, since 2002 DOE has
    actively treated contaminated groundwater by pumping it
    from the aquifer, treating it, and then returning it to the
    aquifer.
    The Tribe now alleges that this remediation is ineffective.
    According to its allegations, the disposal cell allows rain
    water to flow directly through the aggregated tailings. This is
    so because the tailings cover, which consists of sand and
    small rocks, is permeable. And because the tailings sit atop a
    thin geologic layer, the contaminated rainwater drains through
    the tailings straight into the Navajo aquifer, a source of
    drinking water for nearby residents. There is a suggestion in
    the record that covers like the one purporting to shield the
    tailings at the Mill are “100 to 1000 times” more permeable
    than design targets. The Tribe contends that, in light of this
    situation, the Mill does not meet the regulatory requirement
    that it be effective for at least 200 years.
    11
    B. The Highway 160 Site
    The Highway 160 Site (so-called because it abuts the
    eponymous highway) lies just to the north of the Mill. The
    site comprises sixteen acres of Navajo land. Given its
    proximity to the Mill, it is probably unsurprising that the
    Highway 160 Site is also contaminated by radioactive debris.
    The Navajo Nation Environmental Protection Agency
    (“Navajo EPA”) discovered the contamination in 2003.
    Follow-up surveys and investigations in 2006 and 2007 linked
    the onsite radioactive waste to the Mill and revealed that the
    site had debris buried below ground. All told, there were
    sixteen distinct areas of disturbance in need of soil
    remediation. In addition, there were drums and containers of
    solid and hazardous wastes that had been left on the ground.
    In 2007, in view of the dumping at the site, El Paso brought
    its RCRA citizen claim, as did the Nation in 2010 in its
    intervenor complaint.
    Meanwhile, in 2009, the discoveries at the Highway 160
    Site led Congress to authorize and fund a cleanup. Congress
    included in the Energy and Water Development and Related
    Agencies Appropriations Act of 2009, Pub. L. No. 111-8,
    Div. C, 
    123 Stat. 524
    , 601-30, a $5 million appropriation to
    the DOE to perform “remedial actions . . . at real property in
    the vicinity of the [Mill].” 123 Stat. at 617-18; see also 
    42 U.S.C. § 7922
    . The language of the appropriation makes clear
    that Congress intended the remediation to be done under the
    framework of the Mill Tailings Act.
    In 2010 and 2011, the Tribe and the DOE adopted two
    amendments to a prior cooperative agreement (different than
    the one governing at the Mill). Amendment 021, reprinted in
    12
    J.A. 325-29; Amendment 026, reprinted in J.A. 420-35. Most
    of the $5 million in appropriated funds was given to the
    Navajo EPA to remediate the Highway 160 Site. And in
    Amendment 026, the Nation agreed to the following waiver:
    Pursuant to 42 U.S.C. 7915, as this amendment involves
    remedial action, the Navajo Nation (A) releases the
    United States of any liability or claim thereof by such
    tribe or person concerning such remedial action, and (B)
    holds the United States harmless against any claim
    arising out of the performance of any such remedial
    action.
    Amendment 026 at 2, reprinted in J.A. 421.
    The remediation selected was to excavate the
    contaminated material and transport it offsite. This work had
    commenced in July 2011, although the Navajo EPA was
    unsure whether the funding would be sufficient to complete
    the task and had not determined if the groundwater
    underneath the site was contaminated. See Decl. of Cassandra
    Bloedel ¶¶ 3-5, reprinted J.A. 436-37.
    In 2011, the Government moved to dismiss as moot the
    Nation’s RCRA based on the congressional appropriation, the
    liability waiver, and the then-ongoing remedial work. The
    motion also asserted that El Paso lacked standing to bring a
    RCRA claim on its own at the site. The District Court agreed
    and dismissed the claims. El Paso IV, 847 F. Supp. 2d at 123-
    24.
    C. The Dump
    The allegations concerning the Dump paint a disturbing
    picture of the Government’s inaction in the face of clear
    13
    violations of environmental regulations – a picture that only
    gains texture and detail from a review of the record.
    The Dump is a thirty-acre landfill to the southwest of the
    Mill. It sits mostly on Hopi land, although two acres belong to
    the Navajo Tribe. It is a federal facility and was operated by
    the BIA for approximately fifty years without a RCRA
    permit. Before the BIA ceased operations at the Dump in
    1997, trenches were excavated and filled with trash, and then
    were periodically covered with soil. The site comprises two
    cells where waste was disposed: the “old cell” is a ten-acre
    plot that received waste until about 1980, and the “new cell”
    is a separate twenty acres that received waste thereafter.
    During its operation, the Dump received all manner of
    waste. Locals left their ordinary household trash. The
    Government disposed of hazardous waste at the site,
    including medical wastes deposited by the Department of
    Health and Human Services and the Indian Health Service.
    And beginning in 1968, the United States discarded residual
    radioactive materials and waste from the Mill into the Dump.
    Unsurprisingly, the Dump site is seriously contaminated.
    Testing has revealed that the shallow groundwater in the area
    contains various constituents – including arsenic, selenium,
    and uranium, to name just a few – that do not meet federal
    drinking water standards. And wells installed in 2007 to
    monitor the contamination plume beneath the Dump have
    confirmed contaminant levels above federally allowable
    levels.
    There is a history of governmental inaction at the Dump.
    In 1993, prompted by bad conditions such as daily fires at the
    Dump, local residents served the BIA with a notice of intent
    to sue for open dumping in violation of RCRA and its landfill
    14
    regulations in 40 C.F.R. Part 258. The BIA attempted to close
    the Dump before the October 9, 1997 regulatory deadline
    under Part 258, but failed to do so. This was in part due to the
    discovery of ground water contamination, which meant that
    the dump no longer qualified for closure as a small exempt
    landfill under 
    40 C.F.R. § 258.1
    (f) and was instead subject to
    more stringent requirements for closure. In February 2000,
    EPA issued a notice of potential landfill closure violation but
    never brought an enforcement action. Meanwhile, the BIA has
    repeatedly promised to close the Dump but has gotten only as
    far as conducting preliminary studies – to date, thirty-two of
    them.
    In September 2010 – three years after El Paso initiated
    this lawsuit – the BIA and EPA entered into an
    Administrative Settlement Agreement and Order on Consent
    for Remedial Investigation/Feasibility Study (“Administrative
    Settlement”), reprinted in J.A. 333-88. EPA invoked its
    authority under CERCLA § 104, delegated from the
    President, “to act, consistent with the national contingency
    plan, to remove or arrange for the removal of” a hazardous
    substance, pollutant, or contaminant that has been released (or
    threatens to be released) into the environment. 
    42 U.S.C. § 9604
    (a)(1). The settlement incorporates into its terms a
    more detailed plan of action, entitled the Remedial
    Investigation and Feasibility Study Work Plan (“Workplan”).
    See Workplan, reprinted in part in J.A. 391-419, available in
    full as attachment to Pls.’ Mem. in Opp’n to Mot. to Dismiss,
    El Paso v. United States (No. 1:07-cv-00905-RJL), ECF No.
    73-6.
    Under the terms of the Administrative Settlement, the
    BIA agreed to conduct with EPA oversight a remedial
    investigation and feasibility study. The purpose of the study is
    to “determine the nature and extent of contamination and any
    15
    threat to the public health, welfare, or the environment,” and
    “to identify and evaluate remedial alternatives to prevent,
    mitigate or otherwise respond to or remedy any release or
    threatened release of hazardous substances, pollutants, or
    contaminants at or from the Site.” Admin. Settlement ¶ 9,
    reprinted in J.A. 337-38.
    Soon after the settlement was executed, the Government
    defendants filed a Rule 12(b)(1) motion to dismiss. The
    motion asserted that, under CERCLA § 113(h), the Settlement
    Agreement divested the District Court of jurisdiction to hear
    Appellants’ RCRA claims related to the Dump.
    II. ANALYSIS
    We review de novo the District Court’s dismissal of
    claims for want of subject matter jurisdiction under Rule
    12(b)(1) or for failure to state a claim under Rule 12(b)(6).
    Kim v. United States, 
    632 F.3d 713
    , 715 (D.C. Cir. 2011).
    With respect to each claim, we first consider the Rule
    12(b)(1) grounds for dismissal, if any, as subject matter
    jurisdiction presents a threshold question.

    v. Citizens for a Better Env’t,

    , 94-95 (1998)).
    A. RCRA Claims as to the Dump
    Congress enacted RCRA in response to the “rising tide in
    scrap, discarded, and waste materials.” Am. Mining Cong. v.
    EPA, 
    824 F.2d 1177
    , 1179 (D.C. Cir. 1987) (internal
    quotations omitted). “Primary in RCRA, Congress
    empowered the EPA to regulate solid and hazardous waste.”
    Am. Petroleum Inst. v. EPA, 
    683 F.3d 382
    , 384 (D.C. Cir.
    2012). Citizen suits may be brought against any person,
    including the United States and any other governmental
    instrumentality or agency alleged to be in violation of RCRA.

    42 U.S.C. § 6972
    (a); see also, e.g., Backcountry Against
    Dumps v. EPA, 
    100 F.3d 147
     (D.C. Cir. 1996).
    Appellants each brought RCRA citizen-suit claims
    against the United States and federal agencies relating to the
    Dump and the Highway 160 Site. El Paso Compl. ¶¶ 94-101,
    reprinted in J.A. 76-78; Navajo Compl. ¶¶ 103-12, reprinted
    in J.A. 114-17; see also 
    42 U.S.C. § 6972
    (a). The District
    Court dismissed the RCRA claims with respect to the Dump
    because, it concluded, CERCLA § 113(h) divested it of
    jurisdiction.
    CERCLA provides for the prompt and efficient cleanup
    of hazardous substances. See United States v. City & Cnty. of
    Denver, 
    100 F.3d 1509
    , 1511 (10th Cir. 1996). EPA has
    authority under CERCLA to “command government agencies
    and private parties to clean up hazardous waste sites by or at
    the expense of the parties responsible for the contamination.”
    Gen. Elec. Co. v. EPA, 
    360 F.3d 188
    , 189 (D.C. Cir. 2004)
    (internal quotation marks omitted). In particular, CERCLA
    § 104 “authorizes EPA, whenever any hazardous substance is
    released or is threatened to be released into the environment,
    to undertake two types of response actions: (1) to remove or
    arrange for the removal of the hazardous substance; and (2) to
    provide for remedial actions relating to the release or
    ‘substantial threat of release’ of the substance.” Id. (quoting
    
    42 U.S.C. § 9604
    ). CERCLA’s definition of “hazardous
    substance” draws on RCRA’s standards. 
    42 U.S.C. § 9601
    (14)(C); see also Meghrig v. KFC W., Inc., 
    516 U.S. 479
    , 485 (1996).
    CERCLA § 113(h) insulates EPA removal and remedial
    actions taken pursuant to CERCLA § 104 from judicial
    review. Section 113(h) states in pertinent part that:
    17
    No Federal court shall have jurisdiction under Federal
    law . . . to review any challenges to removal or remedial
    action selected under section 9604 of this title . . . in any
    action except one of the following [exceptions] . . . .
    
    42 U.S.C. § 9613
    (h) (emphasis added). The statute then
    enumerates five exceptions, none of which apply here. As this
    court has previously stated, § 113(h) “effectuates a blunt
    withdrawal of federal jurisdiction.” Oil, Chem. & Atomic
    Workers Int’l Union v. Richardson, 
    214 F.3d 1379
    , 1382
    (D.C. Cir. 2000) (internal quotation marks omitted). And
    indeed it does, so long as its predicates are met.
    The District Court determined that the September 2010
    Administrative Settlement entered into between EPA and the
    BIA provided for “removal” actions under CERCLA § 104.
    El Paso IV, 847 F. Supp. 2d at 117. And the District Court
    reasoned that, because Appellants sought an injunction
    ordering cleanup activities, the RCRA claims were barred as
    “challenges” to the removal actions for which CERLCA
    § 113(h) deprives courts of jurisdiction. Id. at 117-18.
    Appellants do not contest that EPA and BIA’s activities
    at the Dump constitute “removal” actions, nor could they in
    view of the statutory definition of the term. The definition of
    “removal” broadly includes “actions as may be necessary to
    monitor, assess, and evaluate the release or threat of release of
    hazardous substances.” 
    42 U.S.C. § 9601
    (23). The definition
    also encompasses “action taken under section 9604(b) of this
    title,” 
    id.,
     and this incorporated subsection includes studies
    and investigations that EPA “may deem necessary or
    appropriate” whenever EPA is authorized to act under
    CERCLA 104(a) or whenever EPA “has reason to believe
    that a release has occurred or is about to occur,” 
    id.
     § 9604(b).
    Moreover “removal” also includes related “enforcement
    18
    activities.” Id. § 9601(25). Thus, the remedial investigation
    and feasibility study that is a part of the Administrative
    Settlement falls within the compass of a “removal action”
    because the agencies have committed to investigate the
    “nature and extent of contamination” from hazardous
    substances at the Dump. Admin. Settlement ¶¶ 1, 9; accord,
    e.g., Razore v. Tulalip Tribes of Wash., 
    66 F.3d 236
    , 238-39
    (9th Cir. 1995) (concluding that performing such a study is a
    “removal action”).
    Notwithstanding the foregoing, Appellants contend that
    § 113(h) should not bar their RCRA claims in this case. First,
    Appellants argue the Government has failed to establish that it
    acted within the scope of its CERCLA § 104 authority, which
    cannot be invoked to clean up substances that are naturally
    occurring. Second, Appellants contend the Administrative
    Settlement and incorporated Workplan cannot serve as the
    predicate for the application of § 113(h) because the
    settlement lacks an objective indicator of when remediation
    will occur. Third, Appellants argue that claims that predate
    the Government’s invocation of CERCLA, like their own,
    cannot be “challenges” to CERCLA response actions within
    the meaning of § 113(h). And fourth, the RCRA claims are
    also not “challenges,” in Appellants’ view, because enforcing
    the requirements in Part 258 will not delay or interfere with
    the CERCLA response action. Br. for Appellant El Paso
    Natural Gas Co. (“El Paso Br.”) at 21-55; see also Br. for
    Appellant Navajo Nation (“Navajo Br.”) at 54 n.12 (joining
    El Paso’s arguments).
    1.   CERCLA § 104 Authority
    EPA’s authority under CERCLA § 104 is limited by
    subsection (a)(3), which provides in relevant part that the
    “President [and EPA, by delegation,] shall not provide for a
    19
    removal or remedial action under this section in response to a
    release or threat of release . . . of a naturally occurring
    substance in its unaltered form, or altered solely through
    naturally occurring processes or phenomena, from a location
    where it is naturally found.” 
    42 U.S.C. § 9604
    (a)(3)(A).
    Citing this provision, Appellants argue that “the factual record
    shows that any hazardous substances at the [Dump] most
    likely are naturally occurring, making CERCLA
    inapplicable.” El Paso Br. at 29; see also 
    id. at 25-26
     (quoting
    snippets from the Workplan that, in the aggregate, stand for
    little more than the straightforward proposition that some
    substances at the Dump are naturally occurring). Appellants
    further contend that, insofar as a material jurisdictional fact is
    in dispute – i.e., whether the substances are “naturally
    occurring” – they are entitled to limited jurisdictional
    discovery. 
    Id.
     at 30 & n.5 (citing Phoenix Consulting, Inc. v.
    Republic of Angola, 
    216 F.3d 36
     (D.C. Cir. 2000)).
    The chief impediments to Appellants’ arguments are their
    own pleadings. El Paso’s complaint repeatedly alleges that
    non-naturally occurring hazardous substances were released at
    the Dump. E.g., El Paso Compl. ¶¶ 13, 17, 19-22, 79-87,
    92-94, 105, 108, reprinted in J.A. 88-116. El Paso would have
    us ignore its own allegations, but factual allegations in
    operative pleadings are judicial admissions of fact. See
    Official Comm. of Unsecured Creditors of Color Tile, Inc. v.
    Coopers & Lybrand, LLP, 
    322 F.3d 147
    , 167 (2d Cir. 2003)
    (“[T]he allegations in the [operative complaint] are judicial
    admissions by which [the pleader] was bound throughout the
    course of the proceeding.” (internal quotation marks and
    alterations omitted)); Schott Motorcycle Supply, Inc. v. Am.
    Honda Motor Co., Inc., 
    976 F.2d 58
    , 61 (1st Cir. 1992) (“A
    party’s assertion of fact in a pleading is a judicial admission
    by which it normally is bound throughout the course of the
    proceeding.” (internal quotation marks omitted)). The same
    20
    goes for the Tribe, see, e.g., Navajo Compl. ¶ 20, reprinted in
    J.A. 146-47, which has also forfeited this argument by stating
    in its brief that it “understands that non-naturally occurring
    contaminants are present in the . . . Dump,” Navajo Br. at 54
    n.12.
    It is of course true that El Paso was entitled to plead in
    the alternative and, to the extent it did so, to not be bound in
    one claim by an allegation pled only as to its alternative
    claim. See FED. R. CIV. P. 8(d)(2); Schott Motorcycle Supply,
    
    976 F.2d at
    61-62 (citing 5 WRIGHT & MILLER, FEDERAL
    PRACTICE AND PROCEDURE § 1282). But that is not what
    happened. El Paso incorporated all of the allegations cited
    above in its RCRA claim. El Paso Compl. ¶ 103, reprinted in
    J.A. 114. And certain allegations were plainly made in view
    of the RCRA claim. Id. ¶ 13, reprinted in J.A. 88-89 (alleging
    that RCRA was violated due to the Government’s storage and
    disposal of, inter alia, “medical waste”).
    Appellants’ allegations foreclose their arguing that the
    substances at the Dump are only “naturally occurring.” For
    the purposes of this proceeding, their pleadings operate as a
    judicial admission that man-made hazardous waste exists at
    the Dump, a fact that is fatal to their argument under
    CERCLA § 104(a)(3). In light of Appellants’ admissions,
    limited jurisdictional discovery was not required. And we do
    not consider El Paso’s argument, raised for the first time in its
    reply brief, that EPA lacked § 104 authority in light of the
    definition of “release” in CERCLA § 101(22), which excludes
    any “release of source, byproduct, or special nuclear material
    from any processing site designated under” the Mill Tailings
    Act. El Paso Reply at 10-11 (quoting 
    42 U.S.C. § 9601
    (22)).
    We have no occasion to address, and we certainly do not
    endorse, the Government’s argument that a suit questioning
    21
    EPA’s authority to invoke CERCLA is itself a “challenge”
    barred by CERCLA § 113(h). Br. for the Fed. Defs. (“Gov’t
    Br.”) at 38-39. The absolutism of the Government’s position
    is striking. At oral argument, in response to a hypothetical,
    counsel for the Government stated that the § 113(h) bar would
    apply even if EPA said that it was invoking § 104 as to a site
    that it knew to be contaminated with substances that were
    exclusively naturally occurring. Later avenues for challenge
    exist, counsel suggested, such as in a defense to a cost-
    recovery action or by bringing a CERCLA citizen suit once
    the response action is completed. When this position is
    coupled with the Government’s additional claim that EPA is
    not constrained by any time limits on when it must finish
    ongoing CERCLA actions, the scope of § 113(h) is stretched
    well beyond what Congress contemplated when the statutory
    bar was enacted.
    In Frey v. EPA, 
    403 F.3d 828
     (7th Cir. 2005), the
    Seventh Circuit raised similar concerns about the
    Government’s construction of § 113(h):
    [W]hat if EPA decides to study the contamination for an
    indeterminate period of time without taking any remedial
    action? Counsel had no response when asked whether the
    statute precludes review if EPA claims that it will take
    action, after further study, at some point before the sun
    becomes a red giant and melts the earth. We then asked
    counsel whether a reviewing court could . . . compel
    agency action unlawfully withheld or unreasonably
    delayed, if EPA dragged its feet for decades. Counsel
    informed us that a court could not act under these
    circumstances because CERCLA’s rules governing
    judicial review override the APA. . . . We can only
    conclude from this exchange that EPA considers itself
    protected from review under CERCLA § 113(h) as long
    22
    as it has any notion that it might, some day, take further
    unspecified action with respect to a particular site.
    Id. at 834.
    The Government’s position is dubious, to say the least: If
    EPA’s ipse dixit is enough to trigger § 113(h), and if EPA can
    also do nothing for as long as it pleases, then CERCLA
    § 113(h) becomes a license for EPA to do as it will for as long
    as it would like, all the while free of judicial review. And
    where federal facilities are involved, this carte blanche has the
    potential to be used by the Government to avoid liability. We
    doubt this is what Congress intended in CERCLA § 113(h). In
    this case, however, having found that Appellants are in fact
    challenging CERCLA action, it is enough for this court to join
    the Seventh Circuit in highlighting the problem as one that is
    ripe for congressional consideration.
    2.   Frey’s “Objective Indicator” Limitation
    Relying on Frey, Appellants next argue that § 113(h)
    prohibits suits only when the Government provides an
    “objective indicator that allows for external evaluation, with
    reasonable target . . . completion dates, of the required work
    for the site.” El Paso Br. at 31 (quoting Frey, 
    403 F.3d at 835
    ). This line of argument is perplexing, both because the
    issue raised in Frey is not the same issue that we face in this
    case and because the limitation it announces would not apply
    to the facts before us.
    Frey addresses the question whether a CERCLA citizen
    suit under 
    42 U.S.C. § 9659
     may proceed under CERCLA
    § 113(h)(4), which is one of the five enumerated exceptions to
    the subsection’s general ban on challenges to CERCLA
    actions. 
    403 F.3d at 829
    . That case concerned a “remedial
    23
    action,” not a “removal,” a distinction that matters under
    § 113(h)(4). Id. at 835-36. EPA had concluded one phase of
    its remedial action (excavating polychlorinated biphenyls);
    however, the agency had not “selected” a remedy for the next
    phase, which concerned groundwater or sediment
    contamination. Id. at 833. The court rejected EPA’s argument
    that § 113(h) barred CERCLA citizen suits indefinitely while
    EPA considered its next remedial action. Id. at 834. Unlike in
    Frey, there is no doubt that in this case the actions taken
    pursuant to the Administrative Settlement, including the
    incorporated Workplan, constitute a “removal” that has been
    “selected” under § 113(h). In any case, it would be impossible
    to apply § 113(h)(4), which Frey relied upon for this
    distinction, because Appellants did not bring a CERCLA
    citizen suit. Appellants’ argument thus amounts to a non
    sequitur.
    The Frey argument also fails on its own terms as the
    Administrative Settlement in this case would pass the
    “objective indicator” test articulated in Frey. In Frey, EPA’s
    CERCLA efforts had come to a standstill, although the
    agency continued to claim that it would – someday – take
    remedial action. EPA then attempted to use § 113(h)(4),
    which blocks citizen suits while “a remedial action is to be
    undertaken at the site,” as a fig leaf to cover its indefinite
    delay. This situation is not before us; under the terms of the
    Administrative Settlement, the BIA is required to conduct the
    remedial investigation and feasibility study under a specific
    schedule. Admin. Settlement ¶¶ 11(t), 31, reprinted in J.A.
    343, 349-50. The incorporated Workplan schedule provides
    specific deadlines for the subtasks involved in finishing the
    study. Table 5, Conceptual Project Timeline (attached to
    Workplan), reprinted in J.A. 417. To be sure, these deadlines
    can be modified, see Admin. Settlement ¶ 33, and it appears
    that some have been modified. But this possibility does not
    24
    render the Administrative Settlement devoid of objective
    indicators for completion. Indeed, the agreement has
    benchmarks that would enable a court to determine if the
    agencies were unduly delaying their removal action and
    distorting § 113(h) into an “open-ended prohibition on a
    citizen suit.” Frey, 
    403 F.3d at 834
    .
    3.   Temporal Limitation to “Challenges”
    Section 113(h) applies only to “challenges to removal or
    remedial action,” 
    42 U.S.C. § 9613
    (h) (emphasis added), and
    Appellants offer two arguments why their RCRA claims are
    not “challenges.” The first is a temporal argument: Appellants
    contend that the term “challenges” encompasses only suits
    filed after the initiation of a CERCLA response action. (We
    consider the second argument in Section II.A.4, infra.) They
    reason that the jurisdictional bar in § 113(h) does not apply
    here because their RCRA claims predate the initiation of the
    CERCLA removal action. El Paso Br. at 35. In support,
    Appellants invoke the purported plain meaning of the statute,
    congressional intent, and the canon that statutory provisions
    should, if possible, be construed in harmony. Id. at 36-46. We
    are unconvinced.
    The meaning of § 113(h), though not plain, supports the
    Government’s position that the § 113(h) bar applies to
    Appellants’ RCRA claims at the Dump. The operative text
    states that “[n]o Federal court shall have jurisdiction . . . to
    review any challenges to removal or remedial action selected
    under section 9604 . . . in any action except one of the
    following” five exceptions. 
    42 U.S.C. § 9613
    (h) (emphasis
    added). Appellants assert that “[o]ne cannot issue a challenge
    against something that does not exist,” and, thus, by
    construing “Appellants’ RCRA claims as a challenge to
    EPA’s later-initiated response action, the [District Court]
    25
    disregarded the ordinary meaning of a ‘challenge.’” El Paso
    Br. at 36. The statute, however, refers to “any challenges,”
    which favors a broad reading of the term to include challenges
    that were so when filed and later-developing challenges. In
    other words, so long as Appellants’ RCRA claims are live,
    they are meant to challenge governmental action (or inaction)
    that is contrary to RCRA, which includes such action taken
    (or forgone) after Appellants’ claims were first advanced to
    initiate this law suit.
    We find no basis in the legislative history to doubt our
    construction of the text. Appellants cite a House Report that
    states that the “purpose of this provision is to ensure that there
    will be no delays associated with a legal challenge of the
    particular removal or remedial action selected under section
    104.” H.R. REP. NO. 99-253, pt. 5, at 25-26 (1985). But this
    reference suffers from the same basic ambiguity as the
    statutory text, i.e., whether a challenge must be intended as
    such from the start or whether a claim can become a challenge
    to a later-filed CERCLA removal or remedial action. If
    anything, this report underscores the importance to Congress
    of minimizing litigation-related delays to CERCLA cleanups,
    and Appellants have offered no persuasive reason why
    Congress would want to treat differently the two types of
    litigation-related delays (i.e., delay caused by preexisting
    claims and delay caused by claims filed after CERCLA
    response actions). Delay is delay, and both the natural reading
    of § 113(h) and the apparent purpose of the subsection
    support our construing “challenges” without regard to the
    strict chronology of when a particular claim is filed.
    Nor are we convinced by Appellants’ assertion that the
    District Court’s interpretation of § 113(h) failed to harmonize
    § 113(h) with RCRA. Our task is to determine what Congress
    intended when it enacted § 113(h), and we cannot, under the
    26
    guise of harmonizing statutes, ignore convincing indicia of
    congressional intent. Congress drafted § 113(h) just two years
    after enacting the RCRA citizen suit provision, and yet it did
    not except RCRA from the sweep of § 113(h). See River Vill.
    W. LLC v. Peoples Gas Light & Coke Co., 
    618 F. Supp. 2d 847
    , 852-53 (N.D. Ill. 2008). And it is clear that Congress
    knew how to preserve RCRA rights when it so desired. See 
    42 U.S.C. § 9620
    (i) (“Nothing in this section shall affect or
    impair the obligation of [the Government] to comply with any
    requirement of [RCRA].” (emphasis added)). But it did not.
    And like many other circuits, we are satisfied that Congress
    did not intend to afford RCRA citizen suits special protection
    from the preemptive sweep of § 113(h). See, e.g., Cannon v.
    Gates, 
    538 F.3d 1328
    , 1332-36 (10th Cir. 2008); OSI, Inc. v.
    United States, 
    525 F.3d 1294
    , 1297-99 (11th Cir. 2008);
    APWU v. Potter, 
    343 F.3d 619
    , 624 (2d Cir. 2003); Clinton
    Cnty. Comm’rs v. EPA, 
    116 F.3d 1018
    , 1026-28 (3d Cir.
    1997); McClellan Ecological Seepage Situation v. Perry, 
    47 F.3d 325
    , 328-30 (9th Cir. 1995); Ark. Peace Ctr. v. Ark.
    Dep’t of Pollution Control & Ecology, 
    999 F.2d 1212
    , 1217-
    18 (8th Cir. 1993).
    4.   When a Claim Qualifies as a “Challenge”
    Appellants also suggest that their claims are not
    “challenges” under § 113(h) because requiring the BIA to
    comply with RCRA’s Part 258 landfill regulations at the
    Dump will not delay or affect any CERCLA cleanup at the
    site. El Paso Br. at 47. In other words, Appellants aim to
    answer this important question: Under what circumstances
    does a claim qualify as a “challenge” under § 113(h)?
    Other circuits that have addressed this question have
    applied a “broad standard for what constitutes a challenge.”
    Cannon, 
    538 F.3d at 1336
    . These courts have found that
    27
    lawsuits qualify as “challenges” under § 113(h) when they
    would create “the kind of interference with the cleanup plan
    that Congress sought to avoid or delay by the enactment of
    Section 113(h).” McClellan, 
    47 F.3d at 330
    ; see also, e.g.,
    Cannon, 
    538 F.3d at 1335
     (“[A] suit challenges a removal
    action if it interferes with the implementation of a CERCLA
    remedy because the relief requested will impact the removal
    action selected.” (emphasis added) (alteration, internal
    quotation marks, and citation omitted)); Broward Gardens
    Tenants Ass’n v. EPA, 
    311 F.3d 1066
    , 1072 (11th Cir. 2002)
    (“To determine whether a suit interferes with, and thus
    challenges, a cleanup, courts look to see if the relief requested
    will impact the remedial action selected.” (emphasis added)).
    We believe the approach taken by these circuits is
    consistent with the operative language and purpose of
    § 113(h). We therefore hold that a claim is a § 113(h)
    “challenge” if it will interfere with a “removal” or a “remedial
    action.” In some situations, the nature and degree of
    interference are sufficiently direct and clear that it will be
    obvious that the suit is a “challenge” barred by § 113(h). See,
    e.g., Boarhead Corp. v. Erickson, 
    923 F.2d 1011
    , 1012 (3d
    Cir. 1991) (concluding that § 113(h) barred jurisdiction over a
    request to stay a CERCLA cleanup until EPA conducted a
    review of the site as required under the National Historic
    Preservation Act). In other situations, it may be necessary to
    assess the nexus between the nature of the suit and the
    CERCLA cleanup: the more closely related, the clearer it will
    be that the suit is a “challenge.” See McClellan, 
    47 F.3d at 330
    . As the Ninth Circuit explained,
    every action that increases the cost of a cleanup or diverts
    resources or personnel from it does not thereby become a
    “challenge” to the cleanup. The enforcement of minimum
    wage requirements, for example, might increase the cost
    28
    of a cleanup and even divert personnel from cleanup
    duties without becoming a challenge to the cleanup. [The
    plaintiff’s RCRA] lawsuit, however, is far more directly
    related to the goals of the cleanup itself than is the
    hypothetical minimum wage action. [The plaintiff], for
    all practical purposes, seeks to improve on the CERCLA
    cleanup as embodied in the [agreement].
    
    Id.
     (emphasis added); see also Gen. Elec., 
    360 F.3d at 194
    (concluding that pre-enforcement judicial review of a facial
    constitutional challenge to CERCLA was permissible under
    § 113(h), notwithstanding the concern that the challenge, if
    successful, “would have the effect of hindering or delaying
    EPA’s cleanup of hazardous waste sites” (emphasis added)).
    Under this framework, there can be little doubt that
    Appellants’ RCRA claims are “challenges.” This conclusion
    is evident from Appellants’ pleadings. See El Paso Compl.
    ¶ H, reprinted in J.A. 118 (seeking “a permanent injunction
    ordering that Defendants perform cleanup activities”); Navajo
    Compl. ¶¶ I.3, I.6, reprinted in J.A. 174 (seeking an
    injunction requiring Defendant to “perform clean-up
    activities” and to “provide financial and technical assistance
    to the Navajo Nation to carry out the activities necessary to
    effect clean closure” of the Dump). The requested relief in
    this case goes beyond interfering with an ongoing CERCLA
    removal action. The injunction that Appellants seek would
    require specific cleanup activities that would threaten to
    obviate the very point of the remedial investigation and
    feasibility study. As noted above, the point of the study is to
    analyze the extent of contamination and to evaluate different
    remedial alternatives so that the Government will be able to
    choose the “remedial action” that is “appropriate under the
    circumstances presented” and that will “assure[] protection of
    human health and the environment.” 
    42 U.S.C. § 9621
    (d); see
    29
    also 
    id.
     § 9601(23) (A “removal” includes “actions as may be
    necessary to monitor, assess, and evaluate the release or threat
    of release of hazardous substances.”).
    Nor does our conclusion change if we assume that
    Appellants’ RCRA claims are limited to enforcing “the
    ground water monitoring, interim measures, corrective action
    and other requirements of Part 258.” El Paso Br. at 47. These
    regulations require groundwater sampling, analysis, and, if
    contaminants are detected above allowable standards, an
    assessment and implementation of a “corrective action” – all
    on a specified timetable. 
    40 C.F.R. §§ 258.53
    (e), 258.53(i)
    258.54(c), 258.55(g), 258.57(a)-(b). Claims based on these
    regulations invariably would interfere with the remedial
    investigation and feasibility study and, thus, the CERCLA
    removal. The relief requested by Appellants would alter how
    EPA monitors and assesses the extent of contamination, see
    
    42 U.S.C. § 9601
    (23), and, more importantly, would threaten
    to preempt EPA’s ability to choose the best remedial action
    among a panoply of remedial alternatives that have been
    analyzed in a completed remedial investigation and feasibility
    study according to criteria articulated in CERCLA, not Part
    258. Compare 
    40 C.F.R. § 300.430
    (e)(9)(iii) (listing nine
    criteria for analyzing remedial alternatives as part of the
    feasibility study), with 
    40 C.F.R. § 258.57
    (b) (listing factors
    for selecting corrective remedies under RCRA’s Part 258).
    That the RCRA claims are “directly related to the goals
    of the cleanup itself” bolsters our conclusion that they are
    “challenges” under § 113(h). McClellan, 
    47 F.3d at 330
    . One
    of the four express purposes of the Administrative Settlement
    is to “ensure compliance with the groundwater monitoring
    requirements of 40 C.F.R. Part 258.” Admin. Settlement
    ¶ 9(d), reprinted in J.A. 338. It is true that CERCLA § 121(d)
    directs compliance with RCRA standards only with respect to
    30
    the “remedial action” selected (not as to a “removal”
    selected), 
    42 U.S.C. § 9621
    (d)(2)(A); however, the Workplan
    structures the remedial investigation and feasibility study in
    light of EPA’s eventual obligation under the statute. See
    Workplan at 36 (“Section 121(d) of CERCLA requires
    attainment of federal, state and Tribal [requirements].”);
    Table 2, “Applicable or Relevant and Appropriate
    Requirements” (attached to Workplan) at 5 (listing 
    40 C.F.R. § 258.58
     as an applicable requirement and summarizing the
    requirement as follows: “Municipal landfill groundwater
    monitoring, provides substantive requirements for
    groundwater detection monitoring, assessment monitoring,
    remedy selection and implementation of corrective actions”).
    In other words, because the remedial action must comply with
    RCRA, it is reasonable to assume that EPA must conduct its
    remedial investigation and feasibility study to evaluate
    remediation which will comply with these obligations. The
    remedial investigation and feasibility study is thus guided,
    albeit indirectly, by the very regulations that Appellants seek
    to enforce judicially.
    Appellants cite United States v. Colorado, 
    990 F.2d 1565
    (10th Cir. 1993), for the proposition that bringing a RCRA
    enforcement claim does not constitute a “challenge” under
    § 113(h). However, Colorado is readily distinguishable
    because that case involved a state’s attempt to enforce its
    hazardous waste requirements. Id. at 1576 (citing 
    42 U.S.C. § 9614
    (a), providing that “[n]othing in [CERCLA] shall be
    construed or interpreted as preempting any State from
    imposing any additional liability or requirements with respect
    to the release of hazardous substances within such State”); see
    also Ark. Peace Ctr., 
    999 F.2d at 1217
     (noting that in
    Colorado “the court relied on 
    42 U.S.C. § 9614
    (a)” which is
    not implicated here).
    31
    5.   The District Court’s Dismissal With Prejudice
    Finally, Appellants argue that, even if their RCRA claims
    must be dismissed pursuant to CERCLA § 113(h), the
    dismissal should have been without prejudice. We agree.
    Although § 113(h) effects a withdrawal of jurisdiction
    whenever its predicates are met, the statutory provision –
    covering only the “Timing of review” – does not permanently
    withdraw jurisdiction over otherwise viable RCRA claims and
    claims arising under one of the exceptions to § 113(h).
    The Government acknowledges that after a remedial
    investigation and feasibility study is completed, “EPA could
    determine that no further remediation work is necessary.”
    Gov’t Br. at 47. We can find nothing in the statute that
    obviously bars a renewed RCRA claim after a removal or
    remedial action has concluded. The Government simply
    states, in conclusory terms, that RCRA claims arising after a
    removal or remedial action has concluded should be barred by
    CERCLA § 113(h) as impermissible “challenges” to the
    removal or remedial actions. This seems contrary to the
    statute because once a removal or remedial action has
    concluded there would be no “removal” or “remedial action”
    contemplated by the Government that a renewed suit would
    “challenge.” 
    42 U.S.C. § 9613
    (h).
    If the Government were to choose not to pursue remedial
    action, Appellants concededly might elect to bring a claim
    under CERCLA’s citizen suit provision. 
    42 U.S.C. § 9613
    (h)(4) (exempting CERCLA citizen suits from the
    subsection’s jurisdictional bar), § 9621(d)(2) (requiring
    CERCLA remedial action to meet RCRA standards that are
    “legally applicable”), § 9659(a)(2) (authorizing citizen suits if
    EPA fails to perform a non-discretionary duty); see also
    Gov’t Br. at 35-36. That a cause of action under CERCLA’s
    32
    citizen suit provision may be available, however, does not
    mean that this cause of action must be the exclusive vehicle
    for seeking additional remedial action at the Dump.
    In any event, we need not decide whether renewed
    RCRA claims may be brought after a removal or remedial
    action has concluded. As we have explained, the Appellants’
    position on this point is far from untenable, but this is a
    difficult issue that admits of no easy answer. Therefore, we
    agree that Appellants’ current RCRA claims should be
    dismissed without prejudice because any question regarding
    the applicability of CERCLA § 113(h) to renewed RCRA
    claims is unripe for review at this time. We leave resolution of
    this question for another day. The District Court’s dismissal
    with prejudice is therefore reversed.
    B. RCRA Claims as to the Highway 160 Site
    The RCRA claims at the Highway 160 Site remain for
    our consideration. The District Court ruled that the Nation’s
    RCRA claim was mooted by the congressional appropriation
    for site remediation and by the Tribe’s agreeing to the liability
    release in Amendment 026. El Paso IV, 847 F. Supp. 2d at
    123-24. This was error. The congressional appropriation and
    the agreements between the Nation and the DOE are
    insufficient to moot the Nation’s RCRA claim.
    The mootness limitation is constitutional:
    Because the exercise of judicial power under Article III
    depends upon the existence of a case or controversy, a
    federal court may not render advisory opinions or decide
    questions that do not affect the rights of parties properly
    before it. See North Carolina v. Rice, 
    404 U.S. 244
    , 246
    (1971) (per curiam). A court’s judgment must resolve “a
    33
    real and substantial controversy admitting of specific
    relief through a decree of a conclusive character, as
    distinguished from an opinion advising what the law
    would be upon a hypothetical state of facts.” 
    Id.
     This
    means that an actual controversy must exist at all stages
    of judicial review, not merely when the complaint is
    filed. See Roe v. Wade, 
    410 U.S. 113
    , 125 (1973).
    EDWARDS, ELLIOTT & LEVY, FEDERAL STANDARDS OF
    REVIEW 134 (2d ed. 2013). And a court must “refrain from
    deciding [a case that was live when filed] if ‘events have so
    transpired that the decision will neither presently affect the
    parties’ rights nor have a more-than-speculative chance of
    affecting them in the future.’” Clarke v. United States, 
    915 F.2d 699
    , 701 (D.C. Cir. 1990) (en banc) (quoting
    Transwestern Pipeline Co. v. FERC, 
    897 F.2d 570
    , 575 (D.C.
    Cir. 1990)).
    The congressional appropriation for site remediation
    certainly did not render the Tribe’s claim moot. The
    appropriation merely offers some support for relief efforts,
    but it does not guarantee remedial results, nor by its terms
    does it bar the Tribe’s present action. Likewise, the Tribe’s
    execution of the liability release in Amendment 026 did not
    moot its current claim as to the Highway 160 Site. The release
    in Amendment 026 does not sweep nearly so broadly as the
    District Court thought.
    The District Court relied on clause (A) of the waiver but
    omitted key phrasing. In relevant part, the waiver states:
    “Pursuant to 42 U.S.C. 7915, as this amendment involves
    remedial action, the Navajo Nation (A) releases the United
    States of any liability or claim thereof by such tribe or person
    concerning such remedial action . . . .” Amendment 026 at 2,
    reprinted in J.A. 421 (emphasis added). The first clause refers
    34
    to the Mill Tailings Act, and the phrasing of the second clause
    establishes a link between “remedial action” and the Act. This
    language makes clear that the Tribe and DOE contemplated in
    this release a specific type of remedial action, namely that
    taken under the authority of the Mill Tailings Act.
    Simply put: the agreement does not contemplate a release
    of liability “concerning any remedial action,” it only releases
    liability “concerning such remedial action.” And the Tribe’s
    RCRA claim is not one “concerning such remedial action.”
    Among other things, the Tribe seeks to enforce RCRA
    regulations that require the implementation of a “ground
    water monitoring” program. Navajo Compl. ¶ 76, reprinted in
    J.A. 162-63. Ground water remediation “concerns such
    remedial action” only insofar as it would take place at the
    same location, albeit on different strata. As the Tribe
    explained, the remedial action selected at the Highway 160
    Site “only concerns soil,” Navajo Br. at 58, which the
    Government does not dispute in its brief. Indeed, it would
    make no sense to say that the remediation covered
    groundwater, as it was unclear at the time whether the
    groundwater beneath the site was contaminated. See Bloedel
    Decl. ¶ 5.
    The bottom line is that the Tribe still has an injury caused
    by the Government that can be remediated by requiring
    compliance with RCRA’s groundwater compliance
    regulations. And no events have transpired to moot its claim.
    The District Court’s additional rationale concerning the
    broad purpose of the cooperative agreement is unconvincing.
    It credited the “broad statement of purpose” in Amendment
    026 “to complete remediation of the Highway 160 Site.” El
    Paso IV, 847 F. Supp. 2d at 123. But this quote is but an
    isolated statement from a document which otherwise makes
    35
    clear that the remedial action would entail excavating the
    contaminated materials from the soil, and not some all-
    encompassing remedial action. See Attach. A to Amendment
    026 at 5, reprinted in J.A. 429. More fundamentally, under
    the District Court’s reading, the phrase “concerning such
    remedial action” means the same thing as “concerning the
    Highway 160 Site” or “concerning any remedial action ever.”
    This is not what the waiver says.
    Even if the disputed waiver were ambiguous on the
    question whether it covers the Tribe’s RCRA groundwater
    claims – which it is not – we would resolve the ambiguity in
    the Tribe’s favor. See Ramah Navajo Chapter v. Salazar, 
    644 F.3d 1054
    , 1062 (10th Cir. 2011), aff’d, 
    132 S. Ct. 2181
    (2012) (agreements dealing with Indian affairs have been
    construed liberally in favor of establishing Indian rights).
    Because we conclude that the Tribe’s RCRA claims at
    the Highway 160 Site are not moot, we need not consider
    whether El Paso has standing. Mountain States Legal Found.
    v. Glickman, 
    92 F.3d 1228
    , 1232 (D.C. Cir. 1996) (“For each
    claim, if constitutional and prudential standing can be shown
    for at least one plaintiff, we need not consider the standing of
    the other plaintiffs to raise that claim.”). We therefore reverse
    the District Court’s dismissal of Appellants’ RCRA claims as
    to the Highway 160 Site and remand the case so that these
    claims can be considered on the merits.
    C. The Government’s Contingent RCRA Counterclaim
    The Government filed a counterclaim against El Paso
    under RCRA pursuant to the citizen endangerment provision,
    
    42 U.S.C. § 6972
    (a)(1)(B). Am. Countercl., reprinted in J.A.
    176. Before the District Court, the Government characterized
    its claim as “a protective reciprocal counterclaim,” and
    36
    explained that the claim “ensures that there is a vehicle for the
    Court to equitably apportion cleanup responsibility for the
    properties among responsible parties, including [El Paso],
    should [El Paso] succeed on its RCRA claims.” United States’
    Mem. in Opp’n to Mot. to Dismiss Am. Countercl. at 2, 14-
    15, El Paso v. United States (No. 1:07-cv-00905-RJL), ECF
    No. 59.
    El Paso moved to dismiss the counterclaim, and the
    District Court denied the motion in a minute order. Later,
    however, in light of the dismissal of Appellants’ RCRA
    claims, the District Court dismissed the Government’s
    counterclaim without prejudice. El Paso argues that the
    Government’s counterclaim should have been dismissed with
    prejudice. Even though El Paso prevailed on the
    counterclaim, it is within its rights to “appeal a dismissal
    without prejudice on the grounds that it wants one with
    prejudice.” See Sea-Land Serv., Inc. v. DOT, 
    137 F.3d 640
    ,
    647 n.4 (D.C. Cir. 1998) (citation omitted). El Paso provides
    two grounds why the dismissal should have been with
    prejudice. First, it contends that the Government is not
    authorized to bring a RCRA “citizen suit” under 
    42 U.S.C. § 6972
    (a)(1)(B). El Paso Br. at 57-61. Second, El Paso argues
    that the claim is inadequately pled. 
    Id. at 61-62
    .
    We start with the language of the statute. Subsection
    (a)(1) of the citizen suit provision states:
    Except as provided in subsection (b) or (c) of this section,
    any person may commence a civil action on his own
    behalf . . . (B) against any person, including the United
    States and any other governmental instrumentality or
    agency . . . who has contributed or who is contributing to
    the past or present handling, storage, treatment,
    transportation, or disposal of any solid or hazardous
    37
    waste which may present an imminent and substantial
    endangerment to health or the environment.
    
    42 U.S.C. § 6972
    (a)(1) (emphasis added). RCRA defines
    “person” to include not just individuals but also, inter alia,
    “each department, agency, and instrumentality of the United
    States.” 
    Id.
     § 6903(15). The question for us is whether the
    Government is a “person” who “may commence a civil
    action.” Or, more precisely, whether the federal defendants –
    who, until now, we have referred to as, collectively, the
    “Government” – are “persons” entitled to bring suit.
    The plain import of the operative text of § 6972(a)(1)(B)
    and § 6903(15) settles the issue. The express definition of
    “person” includes the counterclaimants. And subsection
    (a)(1)(B) only confirms this application: the “including”
    clause in § 6972(a)(1)(B) indicates that “person” as used in
    the subsection encompasses the United States. Id.
    § 6972(a)(1)(B) (“against any person, including the United
    States and any other governmental instrumentality or agency”
    (emphasis added)). We read the first use of “person” in pari
    materia with the second mention of the term, which includes
    governmental agencies.
    El Paso’s arguments are unavailing in the face of this
    clear statutory command. It contends that allowing
    governmental entities to bring citizen suits runs contrary to
    the statutory scheme that separately authorizes EPA to bring
    suits on behalf of the United States. 
    42 U.S.C. § 6973
    (a). This
    is a fair point, but EPA is not a counterclaimant and nothing
    in § 6973 expressly limits alternative action taken under the
    citizen suit provision. Permitting federal agencies to sue under
    § 6972(a)(1)(B) will not undermine EPA’s primary
    enforcement authority because a citizen suit, including one
    brought by a federal agency, cannot proceed until 90 days
    38
    after EPA is given notice of the endangerment. Id.
    § 6972(b)(2)(A); see also id. § 6972(d) (giving EPA right to
    intervene).
    El Paso also cites legislative history to suggest that the
    amendment in 1992 that added federal agencies to RCRA’s
    definition of “person” was for a limited purpose: to make
    clear that RCRA waived sovereign immunity for citizen suits
    against federal facilities. El Paso Br. at 60 (citing H.R. REP.
    NO. 102-111, at 5-6 (1991)). The inference El Paso would
    have us draw is that the amendment is therefore not intended
    for other purposes, such as allowing federal agencies to bring
    RCRA citizen suits. But the evidence is mixed or, if anything,
    more supportive of the Government’s interpretation. See S.
    REP. NO. 102-67, at 5 (1991) (“[T]he bill amends the
    definition of person in section 1004(15) of the Solid Waste
    Disposal Act [i.e., RCRA] so that all of the provisions of that
    Act apply in the same manner and to the same extent to both
    Federal and non-Federal persons.”). With the statute as clear
    as it is, El Paso’s arguments on appeal are insufficient for us
    to forgo giving effect to the plain import of the provision. The
    counterclaim was valid under RCRA.
    We are also unconvinced by El Paso’s second argument,
    that the counterclaim is “legally deficient because it contains
    only conditional allegations that do not actually allege an
    endangerment.” El Paso Br. at 61. El Paso observes that the
    counterclaim alleges that “[t]o the extent that either [El Paso]
    or the Navajo Nation establishes, as alleged in their
    complaints, that solid or hazardous waste [at one of the
    relevant sites] may present an imminent and substantial
    endangerment to health or the environment, then [El Paso] is
    liable under [RCRA] section 7002(a)(1)(B), 42 U.S.C.
    6972(a)(1)(B).” Id. (quoting Am. Countercl. ¶ 24). In El
    Paso’s view, this is insufficient under Rule 8(a)(2) because
    39
    the counterclaim does not show that the Government is
    entitled to relief.
    If El Paso conceded that its own RCRA claim was not
    plausible, then perhaps it would have a point. But it does not.
    Its argument is therefore meritless. Counterclaims made
    contingent on the outcome of the principal action are
    permissible. See Springs v. First Nat’l Bank of Cut Bank, 
    835 F.2d 1293
    , 1296 (9th Cir. 1988) (“[A] counterclaim is not
    barred because recovery will depend on the outcome of the
    main action.”); see also WRIGHT & MILLER, FED. PRACTICE &
    PROCEDURE § 1411 (“A counterclaim will not be denied
    treatment as a compulsory counterclaim solely because
    recovery on it depends on the outcome of the main action,
    however. This approach seems sound when the counterclaim
    is based on pre-action events and only the right to relief
    depends upon the outcome of the main action.”).
    We therefore affirm the District Court’s dismissal of the
    Government’s counterclaim without prejudice.
    D. Mill Tailings Act
    Only claims brought by the Nation remain. Of these, we
    turn next to the two claims that allege violations at the Mill of
    the Mill Tailings Act and related regulations. 
    42 U.S.C. §§ 7901-7942
    ; 40 C.F.R. Part 192. The Third Claim for Relief
    contends that the DOE failed to comply with EPA regulations
    requiring the Mill’s remediation to “meet certain design
    criteria and environmental standards,” including the
    requirement that the remediation be designed to “be effective
    . . . for at least 200 years.” Navajo Compl. ¶¶ 90-93 (citing 
    40 C.F.R. § 192.02
    (a)). And the Fourth Claim for Relief alleges
    that the DOE “failed to complete remedial action at the Mill
    before September 30, 1998,” which is the deadline for such
    40
    action under the statute. 
    Id.
     ¶¶ 96-98 (citing 
    42 U.S.C. § 7912
    (a)(1)); see also 
    42 U.S.C. § 7922
    (a)(1). It further
    alleges that DOE failed to “take appropriate action to restore
    groundwater at and near the Mill.” Navajo Compl. ¶ 98.
    The Government argues that these claims are barred for
    want of subject matter jurisdiction because the Mill Tailings
    Act precludes judicial review. Gov’t Br. at 71-75.
    Alternatively, the Government says the Tribe has failed to
    state a claim for relief. 
    Id.
     at 73 n.7, 76-77. The District Court
    agreed that it lacked jurisdiction. El Paso III, 
    774 F. Supp. 2d at 45-47
    . For the reasons that follow, we conclude that the
    District Court had jurisdiction but that dismissal was
    nevertheless appropriate because the two counts fail to state
    viable claims for relief. See EEOC v. St. Francis Xavier
    Parochial Sch., 
    117 F.3d 621
    , 624 (D.C. Cir. 1997)
    (“Although the district court erroneously dismissed the action
    pursuant to Rule 12(b)(1), we could nonetheless affirm the
    dismissal if dismissal were otherwise proper based on failure
    to state a claim under Federal Rule of Civil Procedure
    12(b)(6).”).
    We can make quick work of the Government’s
    suggestion that the District Court lacked jurisdiction. The
    Tribe does not argue that the Mill Tailings Act affords a
    private right of action; rather, it stakes its claim on a cause of
    action under the APA. See 
    5 U.S.C. § 702
    . Furthermore, as
    the Supreme Court has made clear, a plaintiff’s claim under
    the APA is not barred by another statute if the other statute
    does not cover the type of grievance the plaintiff seeks to
    assert under the APA. Match-E-Be-Nash-She-Wish Band of
    Pottawatomi v. Patchak, 
    132 S. Ct. 2199
    , 2205 & n.3 (2012).
    The APA expressly does not afford a cause of action “to
    the extent that . . . statutes preclude judicial review.” 5 U.S.C.
    41
    § 701(a)(1). And the Government contends that the Mill
    Tailings Act “precludes judicial review.” We disagree. We
    can find nothing in the Mill Tailings Act that precludes the
    Tribe’s APA claims here. When considering whether a statute
    bars judicial review, “[w]e begin with the strong presumption
    that Congress intends judicial review of administrative
    action.” Bowen v. Mich. Acad. of Family Physicians, 
    476 U.S. 667
    , 670 (1986). Overcoming this presumption is no easy
    task; indeed, “where substantial doubt about the congressional
    intent exists, the general presumption favoring judicial review
    of administrative action is controlling.” 
    Id.
     at 672 n.3.
    The Government argues that the Mill Tailing Act
    impliedly precluded the District Court from entertaining the
    Tribe’s APA claims because § 7915(a)(1) states that, if the
    Secretary of Energy enters into a cooperative agreement with
    a tribe, the tribe “shall execute a waiver (A) releasing the
    United States of any liability or claim thereof by such tribe or
    person concerning such remedial action and (B) holding the
    United States harmless against any claim arising out of the
    performance of any such remedial action.” 
    42 U.S.C. § 7915
    (a)(1) (emphasis added); Gov’t Br. at 72. This
    argument makes little sense because there is nothing in
    § 7915(a)(1) to indicate that it bars all APA claims. Section
    7915(a)(1) does not by its terms preclude anything; rather, it
    says that, upon entering into a remedial action agreement
    under the Mill Tailing Act, the Tribe must sign a waiver
    agreement that might serve to limit or bar future suits. Section
    7915(a)(1) does not categorically bar all claims under the
    APA, nor does it address the scope of permissible actions
    under the APA. The scope of any waiver that the Tribe signs
    will be relevant in determining whether it may pursue an
    action under the APA, but that is a different matter entirely.
    42
    Furthermore, Congress did explicitly bar review as to
    some DOE action under the Mill Tailings Act, 
    42 U.S.C. § 7912
    (d). This implies that it did not intend judicial review to
    be foreclosed as to other DOE actions, like those challenged
    here. The Government’s arguments have not removed the
    “substantial doubt” that Congress meant to foreclose judicial
    review in these circumstances. Bowen, 
    476 U.S. at
    672 n.3.
    As a result, the presumption of reviewability controls, and the
    District Court had jurisdiction.
    Nonetheless, we agree with the Government that the two
    counts must be dismissed under Rule 12(b)(6). See St. Francis
    Xavier, 
    117 F.3d at 624
    . To begin with, the particular terms of
    the waiver in the cooperative agreement here control the
    disposition of the Third Claim for Relief. See Coop.
    Agreement at 17-18, reprinted in J.A. 214-15. The waiver
    releases the United States of “any liability or claim . . . arising
    out of the performance of any remedial action.” 
    Id.
     (emphasis
    added). In the Third Claim for Relief, the Tribe asserts that
    the Government failed to meet certain design criteria and
    environmental standards. These are clearly matters arising out
    of the “performance” of the “remedial action,” which is
    covered by the waiver. See id. at 4, reprinted in J.A. 200
    (defining “remedial action” as “the assessment, design,
    construction, renovation, reclamation, decommissioning, and
    decontamination activities of DOE” (emphasis added)).
    In the Fourth Claim for Relief, the Tribe alleges that the
    DOE “failed to complete remedial action at the Mill before
    September 30, 1998.” Navajo Compl. ¶ 98. This alleged
    failure to act does not arise out of “performance” under the
    waiver, so it is not directly covered by the waiver. The claim
    is nonetheless flawed because it does not assert any discrete
    duties which the DOE failed to take and which it was obliged
    to take with respect to remedial action. Norton v. S. Utah
    43
    Wilderness Alliance (SUWA), 
    542 U.S. 55
    , 64 (2004) (“[A]
    claim under § 706(1) [of the APA] can proceed only where a
    plaintiff asserts that an agency failed to take a discrete agency
    action that it is required to take.”). A plaintiff may not rely on
    § 706(1) of the APA to advance “broad programmatic
    attack[s].” Id.; see also Section II.E, infra (amplifying the
    holding in SUWA).
    In sum, we conclude that the Mill Tailings Act does not
    preclude judicial review of the Tribe’s claims. But we affirm
    on alternative grounds. The terms of the waiver executed by
    the Tribe plainly bars the Third Claim for Relief. And the
    Fourth Claim for Relief fails to state a claim since it alleges
    no discrete duty to act incumbent on the DOE.
    E. The Indian Dump Cleanup Act and the Indian
    Agricultural Act
    The Tribe pursued two other statutory claims. Its Second
    Claim for Relief alleges that § 3712(b) of the Indian
    Agricultural Act imposes a duty on the Secretary of the
    Interior to comply with tribal law, and that the Secretary has
    violated this duty by violating various incorporated tribal
    laws. Navajo Compl. ¶¶ 84-88, reprinted in J.A. 165-66. And
    its Ninth Claim for Relief alleges that the Indian Health
    Service “failed and refused to consult with the Navajo
    Nation” and thereby violated duties imposed by § 3904 of the
    Indian Dump Cleanup Act. Id. ¶ 120, reprinted in J.A. 170.
    Although this claim mentions only the Dump, id. ¶ 118, we
    assume that, broadly construed, it reaches the Highway 160
    Site as well.
    We evaluate both claims inasmuch as they apply to sites
    other than the Dump (where CERCLA § 113(h) has divested
    the court of jurisdiction). And like the District Court, we
    44
    consider the claims together as they raise issues that fit neatly
    in the same analytical framework. For both, the real dispute is
    whether the Tribe has a viable cause of action, which, in turn,
    depends on two issues: (1) whether the particular statute
    affords an implied private right of action, and, if not, (2)
    whether the Tribe has alleged “final agency action” sufficient
    to invoke APA review.
    1.   Private Right of Action
    After contending before the District Court and in its
    opening brief here that the Indian Agricultural Act creates a
    private right of action, the Tribe concedes in its reply that it
    does not. Navajo Reply at 9 n.5 (acknowledging that the
    statutory language preserving sovereign immunity “is
    inconsistent with a private right of action and the Nation no
    longer asserts that [the Indian Agricultural Act] creates one”);
    see also 
    25 U.S.C. § 3712
    (d).
    The Tribe argues instead that Congress created a right of
    action in the Indian Dump Cleanup Act. If so, it is implied.
    See 
    25 U.S.C. §§ 3901-3908
     (containing no express right of
    action). The guiding principle with respect to implied rights of
    action is legislative intent; the “judicial task is to interpret the
    statute Congress has passed to determine whether it displays
    an intent to create not just a private right but also a private
    remedy.” Alexander v. Sandoval, 
    532 U.S. 275
    , 286 (2001).
    To determine whether Congress intended to afford a private
    remedy against the Government, we look to Cort v. Ash, 
    422 U.S. 66
    , 78 (1975), and “the long line of cases stemming”
    from that decision. Tax Analysts v. Comm’r, 
    214 F.3d 179
    ,
    185 (D.C. Cir. 2000); see also Sandoval, 
    532 U.S. at 287
    (reaffirming the vitality of Cort, 
    422 U.S. 66
    ).
    45
    The Supreme Court in Cort specified four factors to
    determine whether Congress intended to provide an implied
    private right of action:
    (1) whether the plaintiff is one of the class for whose
    benefit the statute was enacted; (2) whether some
    indication exists of legislative intent, explicit or implicit,
    either to create or to deny a private remedy; (3) whether
    implying a private right of action is consistent with the
    underlying purposes of the legislative scheme; and (4)
    whether the cause of action is one traditionally relegated
    to state law, such that it would be inappropriate for the
    court to infer a cause of action based solely on federal
    law.
    Tax Analysts, 
    214 F.3d at
    185-86 (citing Cort, 
    422 U.S. at 78
    ). Applying this test, we conclude that no private right of
    action can be inferred.
    First, private remedies follow private rights, and we
    agree with the District Court that the Act “focuses on the
    regulating agency’s obligations, and not on the rights of the
    protected party.” El Paso III, 
    774 F. Supp. 2d at
    49 (citing
    Sandoval, 
    532 U.S. at 289
    ). We see nothing to indicate that
    the statute implicitly confers a right of action. See Godwin v.
    Sec’y of HUD, 
    356 F.3d 310
    , 312 (D.C. Cir. 2004). As the
    Godwin court explained,
    “In fact, it is difficult to understand why a court would
    ever hold that Congress, in enacting a statute that creates
    federal obligations, has implicitly created a private right
    of action against the federal government, [as] there is
    hardly ever any need for Congress to do so” given that
    agency action can normally be reviewed by a district
    court pursuant to its federal question jurisdiction.
    46
    
    Id.
     (quoting NAACP v. Sec’y of HUD, 
    817 F.2d 149
    , 152 (1st
    Cir. 1987) (Breyer, J.) (emphasis omitted)).
    We hold below that the Tribe has no viable action under
    the APA in this case, but that does not change our analysis
    here. Indeed, if anything, the absence of an APA claim here
    “only reinforces our view that the [statute] creates no implied
    right of action, for it would be quite odd to hold that Congress
    implicitly created a cause of action despite another statute’s
    preclusion of such an action. Given Congress’s presumed
    awareness of the APA’s provisions, we believe – in
    accordance with the holdings of other circuits – that Congress
    would make explicit any intent to create a cause of action in
    these circumstances.” Id. at 312 (citations omitted).
    In the absence of clear indicia of intent to the contrary,
    we hold that the Indian Dump Cleanup Act does not provide
    an implied right to sue.
    2.   APA
    There being no private right of action in either statute, the
    viability of the Tribe’s Second and Ninth Claims for Relief
    turns on whether the Tribe has adequately pled its claims
    under the APA. Both claims allege failures to act. See 
    5 U.S.C. § 706
    (1) (“The reviewing court shall . . . compel
    agency action unlawfully withheld or unreasonably delayed”).
    Such failures to act “are sometimes remediable under the
    APA, but not always.” SUWA, 
    542 U.S. at 61
    . Drawing on the
    “agency action” language in sections 702, 704 and 706(1) of
    the APA, the Supreme Court made clear that to bring a
    “failure to act” claim under § 706(1) of the APA, a plaintiff
    must sufficiently allege “that an agency failed to take a
    47
    discrete agency action that it is required to take.” SUWA, 
    542 U.S. at 64
    ; see also Montanans for Multiple Use v.
    Barbouletos, 
    568 F.3d 225
    , 227 (D.C. Cir. 2009). With these
    two requirements in hand – that the allegedly withheld action
    be (1) “legally required” and (2) “discrete” – we turn to the
    Tribe’s claims and allegations.
    First, with respect to the Indian Agricultural Act claim,
    the Tribe argues that § 3712(a)-(b) imposes on the Secretary
    of the Interior a legal obligation to take discrete agency
    action. This provision states:
    (a) Tribal recognition– The Secretary shall conduct all
    land management activities on Indian agricultural land
    . . . in accordance with all tribal laws and ordinances,
    except in specific instances where such compliance
    would be contrary to the trust responsibility of the United
    States.
    (b) Tribal laws– Unless otherwise prohibited by Federal
    law, the Secretary shall comply with tribal laws and
    ordinances pertaining to Indian agricultural lands,
    including laws regulating the environment and historic or
    cultural preservation, and laws or ordinances adopted by
    the tribal government to regulate land use or other
    activities under tribal jurisdiction. The Secretary shall—
    ...
    (3) upon the request of an Indian tribe, require
    appropriate Federal officials to appear in tribal
    forums.
    
    25 U.S.C. § 3712
    (a)-(b). The Nation argues it has stated a
    viable APA claim because it “alleged that the Secretary was
    not complying with the permitting requirements of the Navajo
    Clean Water Act and was violating the Navajo Nation Civil
    48
    Trespass Act by failing to remove hazardous wastes from the
    Open Dump and the Highway 160 Dump Site.” Navajo Br. at
    28; see also Navajo Compl. ¶¶ 85-88.
    We think these allegations are insufficient to state a claim
    for relief. The chief problem with the Tribe’s argument is that
    the language above does not appear to endow the agency with
    a duty to act; rather, it requires that when the agency does act,
    its action must comport with tribal law. The portion of
    § 3712(b) cited by the Tribe (“the Secretary shall comply with
    tribal laws”) contains only a general follow-the-law directive.
    Cf. 
    25 U.S.C. § 3712
    (b)(3) (which does set forth discrete
    agency action). This sort of provision flunks SUWA’s
    discreteness test. As the District Court put it, the “statute
    simply requires that when the agency acts, it act in
    compliance with tribal law. It does not impose an affirmative
    duty to act for the purpose of preventing violations of tribal
    law.” El Paso III, 
    774 F. Supp. 2d at 50
    . Meanwhile,
    subsection (a) applies only when the Interior Secretary
    conducts “land management activities,” § 3712(a), but the
    Nation has not alleged that the Interior Secretary’s failures to
    act came in the context of such activities.
    Furthermore, insofar as the claim is premised on the
    Navajo Nation Civil Trespass Act and the Government’s
    failure to remove waste from the Dump or Highway 160 Site,
    we lack jurisdiction to hear it. Seeking an injunction to
    remove the hazardous waste from the Dump would plainly
    constitute a “challenge” under CERCLA § 113(h). And such a
    request would be moot as to the Highway 160 Site because,
    unlike with the Tribe’s RCRA claim, the remedial project that
    was implemented there is the very thing that the Tribe says is
    required under tribal law – removing the waste. See Navajo
    Br. at 28. Nor can we comprehend the Tribe’s passing
    reference to the BIA’s discharge of pollutants from the Mill.
    49
    Id. at 45-46. The complaint suggests that the DOE – and not
    the Interior Department – is in charge of the Mill and the
    remedial project there. See Navajo Compl. ¶¶ 23, 25,
    reprinted in J.A. 147-48. And the DOE is free of the duties
    imposed on the Department of Interior under the Indian
    Agricultural Act. 
    25 U.S.C. §§ 3703
    (15) (defining
    “Secretary” as the Secretary of the Interior), 3712(a)-(b)
    (imposing requirements on the “Secretary”).
    Second, an APA claim premised on the Indian Dump
    Cleanup Act also fails. In particular, the Tribe relies on 
    25 U.S.C. § 3904
    . This provision directs the Indian Health
    Service to “provide financial and technical assistance to the
    Indian tribal government . . . to carry out the activities
    necessary to (1) close such dumps; and (2) provide for
    postclosure maintenance of such dumps.” 
    25 U.S.C. § 3904
    (b). The Nation argues that the Indian Health Service’s
    failure “to provide the mandated financial and technical
    assistance” is cognizable under the APA. Navajo Br. at 32.
    This claim falters because the purportedly mandatory
    duty is contingent on a series of predicate acts in subsection
    (a). That is, the duty to provide assistance in subsection (b)
    can only be invoked “[u]pon completion of the activities
    required to be performed pursuant to subsection (a).” 
    25 U.S.C. § 3904
    (b). There is no indication that the outlined
    activities were in fact completed. The District Court so held,
    El Paso III, 
    774 F. Supp. 2d at 50-51
    , and the Tribe did not
    challenge this conclusion in its brief. What is more, the
    assistance required in subsection (b) is made conditional on
    the “priorities developed by the Director.” 
    25 U.S.C. § 3904
    (c). Because there is a predicate to imposing the duty to
    provide assistance, and because the Director of the Indian
    Health Service has discretion in doling out assistance, the
    Nation has not pled any “legally required” duty to act. SUWA,
    50
    
    542 U.S. at 63
    . As such, the dismissal of the Ninth Claim for
    Relief – like that of the Second Claim for Relief – was
    appropriate.
    F. Breach of Trust
    The final matter at issue in this case is the Tribe’s breach-
    of-trust claim. With respect to all three sites, the Tribe alleged
    in its Tenth Claim for Relief that the Government breached
    various duties owed to it under federal common law, assorted
    statutes, and the 1850 Treaty between the Tribe and the
    United States. Navajo Compl. ¶¶ 121-26, reprinted in J.A.
    171. The District Court dismissed the claim based in part on
    its conclusion that the sources of law relied upon by the Tribe
    did not create a cause of action. El Paso III, 
    774 F. Supp. 2d at 52-53
    . We hold, for the reasons discussed below, that the
    Tribe has failed to state a claim for relief because the Tribe
    has not identified a substantive source of law establishing
    specific fiduciary duties, a failure which is fatal to its trust
    claim regardless of whether we read the claim as brought
    under the APA or under a cause of action implied by the
    nature of the fiduciary relationship itself.
    It helps to take a step back. Because the Government is a
    defendant here, the Tribe faces three threshold requirements
    to stating a viable claim for relief at the pleading stage: it
    must establish federal subject matter jurisdiction, a waiver of
    sovereign immunity, and a cause of action. See Floyd v.
    District of Columbia, 
    129 F.3d 152
    , 155 (D.C. Cir. 1997). The
    first of these is simple because the Tribe’s claim turns on
    questions of federal law and, as such, the District Court
    properly enjoyed “arising under” jurisdiction pursuant to 
    28 U.S.C. § 1331
    . Nor is sovereign immunity in dispute. The
    Government has not argued that its immunity precludes the
    trust claim, Gov’t Br. at 78-87, which comes as no surprise
    51
    since the second sentence of § 702 of the APA waives
    sovereign immunity not just for APA claims but also, more
    broadly, for claims “seeking relief other than money
    damages.” 
    5 U.S.C. § 702
    ; see also Chamber of Commerce of
    the U.S. v. Reich, 
    74 F.3d 1322
    , 1328 (D.C. Cir. 1996) (“The
    APA’s waiver of sovereign immunity applies to any suit
    whether under the APA or not.”). The only threshold issue in
    dispute, then, is the third requirement: whether the Tribe has
    identified a viable cause of action and alleged facts sufficient
    to state a plausible claim under that cause of action.
    The Tribe appears to argue that its claim can be
    maintained either (1) under the APA or (2) under a cause of
    action inferred from the fiduciary responsibilities undertaken
    by the Government. See Navajo Br. at 48, 49 n.9. On either
    conception of the claim our inquiry is largely the same
    because, under controlling precedent, a cause of action will be
    inferred from a fiduciary relationship only where a plaintiff
    can identify specific trust duties in a statute, regulation, or
    treaty. And this analysis overlaps with the APA’s requirement
    that a plaintiff allege “that an agency failed to take a discrete
    agency action that it is required to take.” SUWA, 
    542 U.S. at 64
    .
    Before addressing the Tribe’s specific arguments on
    appeal, we turn to the Supreme Court’s case law concerning
    Indian trust claims, and then to the law of the circuit, to
    ascertain the principles that govern.
    1.   Governing Principles
    The existence of a general trust relationship between the
    Government and Indian tribes is long established. See, e.g.,
    Seminole Nation v. United States, 
    316 U.S. 286
    , 296 (1942);
    Cherokee Nation v. Georgia, 
    30 U.S. 1
    , 17 (1831). But this
    52
    general trust relationship alone does not afford an Indian tribe
    with a cause of action against the Government, as the Nation
    acknowledges. Navajo Br. at 53. Something more is needed.
    In decisions addressing Indian trust claims arising in the
    context of the Indian Tucker Act, 
    28 U.S.C. § 1505
    , the
    Supreme Court has inferred causes of action for money
    damages where statutes and regulations establish a
    conventional fiduciary relationship with the Government as
    trustee. We start with these decisions to see when statutes and
    regulations establish a conventional trust relationship and, as
    a result, imply a cause of action for breach of trust. Next, we
    turn to our own Indian trust law precedent, which confirms
    that we apply these same principles to trust claims brought
    under the APA.
    a.   Trust Claims under the Indian Tucker Act
    The Supreme Court, in two pairs of cases, delineated
    what an Indian tribe must establish to bring a breach-of-trust
    claim for money damages against the Government under the
    Indian Tucker Act, 
    28 U.S.C. § 1505
    . See United States v.
    Navajo Nation (Navajo I), 
    537 U.S. 488
     (2003); United States
    v. White Mountain Apache Tribe, 
    537 U.S. 465
     (2003);
    United States v. Mitchell (Mitchell II), 
    463 U.S. 206
     (1983);
    United States v. Mitchell (Mitchell I), 
    445 U.S. 535
     (1980).
    Mitchell I and Mitchell II were decided in the same case,
    which was brought by members of the Quinault Tribe alleging
    that the Government mismanaged timber resources and
    thereby breached its duty as trustee. The posture of Mitchell I
    presented the question whether the Indian General Allotment
    Act of 1887 (“Allotment Act”), also known as the Dawes Act,
    authorized an award of money damages against the United
    States for its mismanagement of forests on land allotted under
    53
    the statute. 
    445 U.S. at 536
    . Section 5 of the Allotment Act
    provided that “the United States does and will hold the land
    thus allotted . . . in trust for the sole use and benefit of the
    Indian to whom such allotment shall have been made.” 
    Id. at 541
     (quoting Allotment Act). But the Supreme Court
    concluded that this language created only a “limited trust
    relationship” that did not impose a judicially enforceable trust
    duty. 
    Id. at 542
    . Rather than enacting particular governmental
    duties, the Court read the Allotment Act as entrusting the
    management of the land to the allottees themselves. 
    Id. at 543
    .
    And the Court was persuaded that the “in trust” language was
    not intended to impose fiduciary duties on the United States,
    but to protect allottees from state taxation. 
    Id. at 544
    .
    Although it rejected the trust claim predicated on the
    Allotment Act, the Court nevertheless allowed that other
    statutes could succeed where the Allotment Act failed. 
    Id.
     at
    546 & n.7.
    Mitchell II considered these other statutes and held that
    they imposed enforceable fiduciary duties, i.e., that they
    created a cause of action for breach of trust. The Court
    distinguished Mitchell I, stating that “[i]n contrast to the bare
    trust created by the General Allotment Act, the statutes and
    regulations [here] clearly give the Federal Government full
    responsibility to manage Indian resources and land for the
    benefit of the Indians. They thereby establish a fiduciary
    relationship and define the contours of the United States’
    fiduciary responsibilities.” 
    463 U.S. at 224
    . The statutes at
    issue established “comprehensive” federal responsibilities to
    manage the harvesting of Indian timber and instructed that
    sales of Indian timber should be “based upon the Secretary’s
    consideration of ‘the needs and best interests of the Indian
    owner and his heirs.’” 
    Id. at 222, 224
     (quoting 
    25 U.S.C. § 406
    (a)).
    54
    Together, Mitchell I and Mitchell II make clear that
    neither the general trust relationship between the federal
    government and Indian Tribes nor the mere invocation of trust
    language in a statute (as in the Allotment Act) is sufficient to
    create a cause of action for breach of trust. As the Court later
    explained, “[a]lthough the undisputed existence of a general
    trust relationship between the United States and the Indian
    people can reinforce the conclusion that the relevant statute or
    regulation imposes fiduciary duties, that relationship alone is
    insufficient to support jurisdiction under the Indian Tucker
    Act. Instead, the analysis must train on specific rights-creating
    or duty-imposing statutory or regulatory prescriptions.”
    Navajo I, 537 U.S. at 506 (emphasis added) (alteration,
    internal quotation marks, and citation omitted).
    In Navajo I and White Mountain – decided the same day
    – a divided Supreme Court further fleshed out these trust
    principles. In Navajo I, the Tribe asserted that the Secretary of
    the Interior committed a breach of trust by approving a sub-
    standard royalty rate in a coal lease on a tract of Indian land.
    537 U.S. at 493. The Tribe argued that the Indian Mineral
    Leasing Act of 1938 assigned to the Secretary a fiduciary
    obligation to maximize returns from coal leases on Indian
    land whenever he exercised his statutory responsibility to
    approve mining leases. Id. at 496. The Court disagreed,
    notwithstanding that it was aware of the fact that the “Tribe’s
    reservation lands . . . are held for it in trust by the United
    States.” Id. at 495. Like the Allotment Act in Mitchell I, the
    Indian Mineral Leasing Act and associated regulations did not
    “assign to the Secretary managerial control over coal leasing.”
    Id. at 508. In fact, the statute and regulations did not “even
    establish the ‘limited trust relationship’” embodied under the
    Allotment Act. Id. (quoting Mitchell I, 
    445 U.S. at 542
    ).
    55
    White Mountain, in contrast, allowed a trust claim to
    proceed. There the Tribe predicated its breach-of-trust claim
    on the “1960 Act,” a paragraph-long statute that declared that
    a 400-acre parcel of land, which had been used as a military
    post and then as a school, was to be “held by the United States
    in trust for the White Mountain Apache Tribe, subject to the
    right of the Secretary of the Interior to use any part of the land
    and improvements for administrative or school purposes for
    as long as they are needed for [that] purpose.” 537 U.S. at 469
    (quoting Pub. L. No. 86-392, 
    74 Stat. 8
     (1960)). The Secretary
    exercised his statutory right of use but allegedly failed to
    maintain the property, and the Tribe sued. The Court allowed
    the claim to proceed. Unlike the Allotment Act in Mitchell I,
    the 1960 Act, if sparsely worded, nevertheless went “beyond
    a bare trust” by investing the United States with
    “discretionary authority to make direct use of portions of the
    trust corpus.” 
    Id. at 474-75
    . Acknowledging that “the 1960
    Act does not, like the statutes cited in [Mitchell II], expressly
    subject the Government to duties of management and
    conservation,” the Court reasoned that “the fact that the
    property occupied by the United States is expressly subject to
    a trust supports a fair inference” of an obligation to preserve
    the trust property. 
    Id. at 475
    .
    Important to the Court’s conclusion in White Mountain
    that the 1960 Act created a cause of action for money
    damages was the fact that the Act afforded the Secretary with
    a right of use and occupancy. Justices Ginsburg and Breyer,
    who joined the majority opinions in both Navajo I and White
    Mountain and who were the deciding votes in both cases,
    authored a concurrence in the latter explaining how the two
    opinions were “not inconsistent.” 
    Id. at 479
     (Ginsburg, J.,
    concurring). In the White Mountain concurrence, Justice
    Ginsburg explained that the “threshold set by the Mitchell
    cases is met” because the 1960 Act “expressly and without
    56
    qualification employs a term of art (‘trust’) commonly
    understood to entail certain fiduciary obligations . . . and
    ‘invest[s] the United States with discretionary authority to
    make direct use of portions of the trust corpus.’” 
    Id. at 480
    (emphasis added) (quoting 537 U.S. at 475); see also id.
    (“The dispositive question . . . is whether the 1960 measure,
    in placing property in trust and simultaneously providing for
    the Government-trustee’s use and occupancy, is fairly
    interpreted to mandate compensation for the harm caused by
    maladministration of the property.” (emphasis added)).
    Collectively, Mitchell I, Mitchell II, White Mountain, and
    Navajo I make clear that, while a cause of action for money
    damages under the Indian Tucker Act can be inferred as a
    concomitant to a specific fiduciary duty owed by the
    Government, a Tribe must first “identify a substantive source
    of law that establishes” that specific fiduciary duty. Navajo I,
    537 U.S. at 506 (emphasis added). This “analysis must train
    on specific rights-creating or duty-imposing statutory or
    regulatory prescriptions.” Id. A statute’s invocation of trust
    terminology is not itself dispositive, since the statute may
    create either a judicially enforceable trust as in White
    Mountain or a “bare trust,” not judicially enforceable, as in
    Mitchell I. What separates a “bare trust” from a bona fide one
    is a matter of statutory interpretation, and the real question is
    whether the particular statute or regulation establishes rights
    and duties that characterize a conventional fiduciary
    relationship.
    These principles control here, even though the claim is
    for equitable relief (not money damages) and even though
    sovereign immunity is waived under § 702 of the APA (and
    not the Indian Tucker Act). A bit of explanation is called for
    since this conclusion is not inevitable. We therefore turn to
    the law of the circuit.
    57
    b. Circuit Precedent
    The Indian Tucker Act confers jurisdiction to the Court
    of Federal Claims and waives sovereign immunity only for a
    limited subset of claims, namely those “arising under the
    Constitution, laws or treaties of the United States, or
    Executive orders of the President, or . . . [claims] which
    otherwise would be cognizable in the Court of Federal Claims
    if the claimant were not an Indian tribe.” 
    28 U.S.C. § 1505
    .
    Because of this limited language, facets of the Supreme
    Court’s Indian Tucker Act jurisprudence may be unique to the
    Indian Tucker Act and, accordingly, not binding on Indian
    trust claims brought outside the Act. See COHEN’S HANDBOOK
    OF FEDERAL INDIAN LAW § 5.05[3][c].
    Although we appreciate this possibility, we nevertheless
    apply the lessons articulated in the Mitchell cases. We do so
    for two reasons: because this been our approach in past cases
    and, as important, because the Tribe has not marshaled an
    argument that we should reconsider our approach. We
    amplify both points below.
    First, we have consistently relied on principles
    announced in Indian Tucker Act cases in trust cases not
    arising under the Act. We stated in North Slope Borough v.
    Andrus, 
    642 F.2d 589
     (D.C. Cir. 1980), that a “trust
    responsibility can only arise from a statute, treaty, or
    executive order; in this respect we are governed by [Mitchell
    I] holding that the United States bore no fiduciary
    responsibility to Native Americans under a statute which
    contained no specific provision in the terms of the statute.” 
    Id. at 611
     (internal quotation marks and footnote omitted);
    accord Shoshone-Bannock Tribes v. Reno, 
    56 F.3d 1476
    ,
    1482 (D.C. Cir. 1995) (“[T]he government’s fiduciary
    58
    responsibilities necessarily depend on the substantive laws
    creating those obligations.” (citing the Mitchell cases)).
    Our decision in Cobell VI, upon which the Tribe relies, is
    not to the contrary. Cobell v. Norton (Cobell VI), 
    240 F.3d 1081
     (D.C. Cir. 2001). It is true that there we quoted Mitchell
    II to say that a “‘fiduciary relationship necessarily arises when
    the Government assumes such elaborate control over forests
    and property belonging to Indians. All of the necessary
    elements of a common-law trust are present: a trustee (the
    United States), a beneficiary (the Indian allottees), and a trust
    corpus (Indian timber, lands, and funds).’” 
    Id. at 1098
    (quoting 
    463 U.S. at 225
    ). However, we said this not to
    suggest that an actionable fiduciary relationship arises merely
    by operation of federal common law. Rather, we explained
    that the common law informs the interpretation of statutes that
    establish the elements of a common-law trust without
    employing the terms of art. The Mitchell II rule, we said,
    “operates as a presumption,” such that “‘where the Federal
    Government takes on or has control or supervision over tribal
    monies or properties, the fiduciary relationship normally
    exists with respect to such monies or properties (unless
    Congress has provided otherwise) even though nothing is said
    expressly in the authorizing or underlying statute (or other
    fundamental document) about a trust fund, or a trust or
    fiduciary connection.’” 
    Id.
     (emphasis added) (quoting 
    463 U.S. at 225
    ). We then reiterated that a fiduciary relationship
    depends on substantive laws, stating that “the government’s
    obligations are rooted in and outlined by the relevant statutes
    and treaties.” Id. at 1099.
    Second, the Tribe has not argued that the principles
    enunciated by the Supreme Court in the Indian Tucker Act
    cases do not control here. To be sure, it drops hints of
    disagreement in its brief – a footnote stating parenthetically
    59
    that some courts “fail to distinguish between” claims for
    money damages and those for equitable relief, Navajo Br. at
    53 n.10, and a clause referring to the “even more rigorous
    jurisdictional requirements of the . . . Indian Tucker Act.”
    Navajo Reply at 12; see also Navajo Br. at 16. But the Tribe
    never propounds a viable theory to contest the applicability of
    the established law of the circuit. Therefore, we are
    constrained to apply the standards articulated in the Indian
    Tucker Act cases to the trust claim before us.
    2.   The Tribe’s Arguments
    The Tribe argues that various statutes establish an
    enforceable fiduciary duty. We disagree.
    a.   25 U.S.C. § 640d-9(a)
    The Tribe’s primary contention on appeal is that, because
    the land in question is subject to an “express trust” under 25
    U.S.C. § 640d-9(a), the Government uses the land subject to
    an enforceable fiduciary duty to manage and preserve the trust
    res, i.e., the occupied tribal land. See Navajo Br. at 50 (citing
    White Mountain, 
    537 U.S. at 475
    ). The Tribe’s position
    reduces to a simple formula: an express trust plus actual
    governmental control equals enforceable trust duties.
    This argument has surface-level appeal based on a loose
    congruence between the claims in White Mountain and here.
    Both involve allegations of governmental control over Indian
    property designated by statute as some sort of trust. And both
    statutes say precious little. Section 640d-9(a) provides that
    certain designated lands “shall be held in trust by the United
    States exclusively for the Navajo Tribe and as a part of the
    Navajo Reservation.” 25 U.S.C. § 640d-9(a) (emphasis
    added). Meanwhile, the statute in White Mountain stated that
    60
    “all right, title, and interest of the United States in and to the
    lands, together with the improvements thereon, included in
    the former Fort Apache Military Reservation . . . are hereby
    declared to be held by the United States in trust for the White
    Mountain Apache Tribe, subject to the right of the Secretary
    of the Interior to use any part of the land and improvements
    for administrative or school purposes for as long as they are
    needed for that purpose.” 74 Stat. at 8 (emphasis added).
    But § 640d-9(a) differs in a crucial respect from the 1960
    Act in White Mountain: It does not afford the government the
    right to use the land in question. This difference, far from
    inconsequential, leads to the conclusion that § 640d-9(a) is a
    “bare trust” in the realm of Mitchell I, i.e., one that does not
    afford the Tribe with a cause of action. As noted above, the
    Supreme Court relied on the Government’s express right of
    use in concluding that the 1960 Act created an enforceable
    cause of action for breach of trust. See White Mountain, 
    537 U.S. at 475
    ; 
    id. at 480
     (Ginsburg, J., concurring). This makes
    sense: It is natural to infer that Congress intended that a
    correlative duty to maintain trust property would attach to an
    expressly provided right of use (if invoked). Unlike the 1960
    Act, § 640d-9(a) offers no hook to find a correlative duty of
    management; the statute includes only the phrase “shall be
    held in trust.” This is not enough, even if paired with
    allegations of governmental control at the Mill, the Dump,
    and the Highway 160 Site, because nothing in the pleadings
    or record suggest that the Government took control of the
    premises pursuant to § 640d-9(a).
    Unable to infer specific fiduciary duties from
    § 640d-9(a), we conclude that the section does not create a
    cause of action for the Tribe. In reaching this conclusion, we
    do not, of course, suggest that an express right of
    governmental use is always necessary to find that a statute
    61
    affords a cause of action for breach of trust. However,
    governmental use may be relevant when a statutory reference
    to “trust” does not itself indicate whether Congress intended
    to establish specific fiduciary duties or a “bare trust” instead.
    Our conclusion in this case is mandated by the Supreme
    Court’s decision in United States v. Navajo Nation (Navajo
    II), 
    556 U.S. 287
     (2009), which was not brought to our
    attention by the parties. On remand after Navajo I rejected a
    trust claim predicated on the Indian Mineral Leasing Act, the
    Federal Circuit relied on 25 U.S.C. § 640d-9(a) combined
    with allegations of control – the very argument pressed here –
    to conclude that the Tribe’s claim was viable after all. Navajo
    Nation v. United States, 
    501 F.3d 1327
    , 1340-41 (Fed. Cir.
    2007). The Federal Circuit reasoned that where “the
    government exercises actual control within its authority,
    neither Congress nor the agency needs to codify such actual
    control for a fiduciary trust relationship that is enforceable by
    money damages to arise.” 
    Id.
     at 1343 (citing White Mountain,
    
    537 U.S. at 475
    ).
    The Supreme Court reversed. Although the Supreme
    Court did not specifically address 25 U.S.C. § 640d-9(a) in
    Navajo II, it rejected the Federal Circuit’s reasoning
    wholesale: “None of the sources of law cited by the Federal
    Circuit and relied upon by the Tribe provides any more sound
    a basis for its breach-of-trust lawsuit against the Federal
    Government than those we analyzed in Navajo I. This case is
    at an end. The judgment of the Court of Appeals is reversed,
    and the case is remanded with instructions to affirm the Court
    of Federal Claims’ dismissal of the Tribe’s complaint.”
    Navajo II, 
    556 U.S. at 302
    .
    Simply put, Navajo II forecloses the Tribe’s arguments
    that § 640d-9(a) plus the Government’s control establishes an
    62
    actionable fiduciary relationship. The Court also makes clear
    that it reached its conclusion without regard to considerations
    unique to money damages. See id. (“Because the Tribe cannot
    identify a specific, applicable, trust-creating statute or
    regulation that the Government violated, we do not reach the
    question whether the trust duty was money mandating.”). As
    the Court explained:
    If a plaintiff identifies such a [rights-creating or duty-
    imposing statutory or regulatory] prescription, and if that
    prescription bears the hallmarks of a “conventional
    fiduciary relationship,” White Mountain, 537 U.S. at 473,
    then trust principles (including any such principles
    premised on “control”) could play a role in “inferring that
    the trust obligation [is] enforceable by damages” . . . . But
    that must be the second step of the analysis, not (as the
    Federal Circuit made it) the starting point.
    Id. at 301.
    b. The Indian Dump Cleanup Act, the Indian
    Agricultural Act, and the Mill Tailings Act
    The Tribe next argues that the Indian Agricultural Act,
    the Indian Dump Cleanup Act, and the Mill Tailings Act also
    impose enforceable trust duties. Navajo Br. at 50. We need
    not tarry long over these claims.
    The Mill Tailings Act does not purport to establish a
    conventional fiduciary relationship with an attendant cause of
    action for breach of trust. To begin with, as we observed in El
    Paso II, the Mill Tailings Act’s “statement of purpose reveals
    that Congress passed the statute to protect public health in
    general rather than tribal health in particular.” 632 F.3d at
    1278 (emphasis added); see also 
    42 U.S.C. § 7901
    (b) (a
    63
    purpose is to “minimize or eliminate radiation health hazards
    to the public” (emphasis added)). Furthermore, unlike the
    statutory language in Mitchell II, which plainly created a
    conventional fiduciary relationship, see 
    463 U.S. at 224
    (observing how a section of a 1910 act mandated that timber
    sales be based on “the needs and best interests” of the Indian
    owners), the language in the Mill Tailings Act manifests no
    similar “hallmarks of a conventional fiduciary relationship,”
    Navajo II, 
    556 U.S. at 301
     (internal quotation marks omitted).
    To the contrary, Congress took pains to insulate the
    Government from liability concerning the remediation, see 
    42 U.S.C. § 7915
    (a)(1), and from judicial review with respect to
    the Secretary of Energy’s designation of sites, see 
    id.
    § 7912(d). The legislative history reinforces our conclusion
    because it suggests that Congress did not intend to alter any
    trust duties, one way or the other. See H.R. REP. NO. 95-1480,
    pt. 2, at 39 (1978) (“The committee does not intend by this act
    to affect the responsibilities of the Secretary of the Interior as
    trustee for any Indian Tribe.”).
    Nor does the Indian Agricultural Act impose
    independently enforceable trust duties. Although the Act
    mentions the Government’s “trust responsibility” in stating its
    findings and purposes, 
    25 U.S.C. §§ 3701
    , 3702, Congress
    was quite clear that “[n]othing in this chapter shall be
    construed to diminish or expand the trust responsibility of the
    United States toward Indian trust lands or natural resources,
    or any legal obligation or remedy resulting therefrom,” 
    id.
    § 3742 (emphasis added). To construe the Act as
    independently creating an enforceable trust responsibility
    would contravene the plain intent of Congress.
    Any trust claim founded on the Indian Dump Cleanup
    Act fares no better. Granted, this statute, like the previous
    one, states in its findings that “the United States holds most
    64
    Indian lands in trust for the benefit of Indian tribes and Indian
    individuals.” 
    25 U.S.C. § 3901
    (a)(5). But the statute does not
    vest in the Government – either expressly as in Mitchell II or
    by implication as in White Mountain – any responsibility for
    management or control of Indian property. To the contrary,
    the statute imposes a duty upon the Director of the Indian
    Health Service to assist tribal governments as they “carry out
    the activities necessary” to close open dumps. 
    Id.
     § 3904(b).
    Because the statute contemplates management and control in
    the hands of tribal governments, the Indian Dump Cleanup
    Act falls comfortably within the ambit of Mitchell I.
    To summarize: none of the cited sources of law – 25
    U.S.C. § 640d-9(a), the Indian Agricultural Act, the Indian
    Dump Cleanup Act, and the Mill Tailings Act – create a
    conventional fiduciary relationship that is enforceable as a
    breach of trust either under the APA or as a separate cause of
    action implied from the nature of the trust relationship as
    provided by the Mitchell doctrine. We therefore have no
    occasion to determine the contours of the fiduciary duties
    owed by the Government. See Navajo Br. at 52 (arguing that
    the cited statutes “establish the contours of trust duties to be
    complemented with principles of general trust law”).
    c.   Other Statutes
    Finally, the Tribe argues that federal agencies, as a
    component of their fiduciary responsibilities, have a minimum
    duty to comply with generally applicable laws if their actions
    affect trust property. Navajo Br. at 52-54. This argument has
    no traction. The Tribe does not contend that, under the
    Mitchell doctrine, these generally applicable statutes afford it
    a cause of action for breach of trust, and for good reason. The
    generally applicable statutes – e.g., RCRA and the Clean
    Water Act – do not establish a conventional fiduciary
    65
    relationship. Therefore, the Tribe’s last argument is without
    merit.
    III. CONCLUSION
    For the reasons stated above, we affirm the judgment of
    the District Court on all but two points. First, we reverse the
    dismissal “with prejudice” of Appellants’ RCRA claims that
    relate to the Dump. We hereby remand with instructions to
    the District Court to enter judgment against Appellants
    “without prejudice.” Second, we vacate the District Court’s
    dismissal of Appellants’ RCRA claims as to the Highway 160
    Site and remand the case so that these claims can be
    considered on the merits.
    So ordered.
