                               I. INTRODUCTION

      Caddo Nation of Oklahoma (“Caddo Nation”) brought suit against Wichita

and Affiliated Tribes (“Wichita Tribe”), asserting Wichita Tribe violated the

National Environmental Policy Act (“NEPA”) and the National Historic

Preservation Act (“NHPA”) during the process of planning to build a Tribal

History Center funded by the Department of Housing and Urban Development

(“HUD”). See Caddo Nation of Okla. v. Wichita & Affiliated Tribes, 

, 1173-74 (10th Cir. 2017). 1 Caddo Nation appealed to this court after the

district court denied a temporary restraining order preventing continuing

construction of the History Center. 

This court held it lacked

jurisdiction because construction of the History Center was completed during the

pendency of the appeal. 

“[T]he relief Caddo Nation requested

from the district court—a temporary restraining order enjoining construction—

[was] now moot.” 

We recognized, however, the possibility Caddo

Nation might have viable NEPA and NHPA claims “regarding the operation of the

Center or other activities on the site.” 

Thus, we remanded for further



      1
         The factual, legal, and procedural background of the dispute between
Caddo Nation and Wichita Tribe over the History Center project is set out at
length in this court’s prior opinion. Caddo Nation of Okla. v. Wichita &
Affiliated Tribes, 

, 1173-76 (10th Cir. 2017). Thus, for the most
part, it is not necessary to restate the background in resolving the instant appeal.
proceedings and specifically noted “Caddo Nation may seek to amend its

complaint or file a new motion for a preliminary injunction on the History

Center’s use pending the outcome of its [NEPA] and [NHPA] claims.” 

filed an amended complaint. Wichita Tribe responded by

filing a motion to dismiss. Wichita Tribe argued all claims set out in the amended

complaint were barred by tribal sovereign immunity and, in any event, Caddo

Nation’s NEPA and NHPA claims were mooted by the completion of the History

Center. The district court concluded all claims set out in the amended complaint,

with the exception of the NEPA and NHPA claims, were barred by tribal

sovereign immunity. 2 As to the NEPA and NHPA claims, the district court

concluded Wichita Tribe agreed to comply with those statutory provisions, and

thereby waived its sovereign immunity, when it accepted money from HUD for

the History Center project. See 42 U.S.C. § 5304(g); 24 C.F.R. §§ 58.2, 58.4,

58.5; see also Caddo 

(noting that by accepting HUD

funds, Wichita Tribes agreed to comply with NEPA and NHPA). Nevertheless,




      2
        Caddo Nation has not challenged the district court’s ruling in this regard.
Accordingly, the only claims from the amended complaint at issue on appeal are
Caddo Nation’s NEPA and NHPA claims. This court has made clear that the
dispute between Caddo Nation, Wichita Tribe, and Delaware Nation over
ownership and/or control of the parcel upon which the History Center was built is
not relevant to Caddo Nation’s NEPA and NHPA claims. Caddo 

n.2. Accordingly, Caddo Nation’s Motion to Take Judicial Notice and
File Supplemental Appendix, which relates solely to that question, is DENIED.

                                        -3-
the district court ruled that Caddo Nation’s NEPA and NHPA claims were mooted

by the completion of the History Center.

      On appeal, Caddo Nation asserts the district court erred in concluding its

NEPA and NHPA claims are moot. Wichita Tribe contests that assertion and, as

an alternate basis for affirming the district court’s order of dismissal, contends the

claims are barred by tribal sovereign immunity. The district court correctly ruled

that Caddo Nation’s NEPA and NHPA claims are not barred by sovereign

immunity. 3 The district court was also correct in concluding that most aspects of


      3
        Wichita Tribe raises various other matters in its response brief in an effort
to offer alternative rationales for affirming the district court’s dismissal of the
amended complaint. None of these matters is worthy of an extended analysis.
The assertion Caddo Nation’s NEPA and NHPA claims are not properly brought
under the Administrative Procedure Act (“APA”) clearly lacks merit. “[A]
plaintiff seeking judicial review pursuant to the APA must (i) identify some final
agency action and (ii) demonstrate that its claims fall within the zone of interests
protected by the statute forming the basis of its claims.” Catron Cty. Bd. of
Comm’rs v. U.S. Fish & Wildlife Serv., 

, 1434 (10th Cir. 1996)
(quotation omitted). Wichita Tribe has never contested that the Finding of No
Significant Impact (“FONSI”) in its Environmental Assessment (“EA”) satisfies
the requirement of final agency action. Furthermore, given that the instant
dispute centers around the possibility the construction site is a burial ground for
members of the Caddo Nation, Caddo 

, the claims “fall
within the zone of interests protected by” NHPA and NEPA. In any event, this
court has already recognized that, at the very least, Caddo Nation’s NEPA claim
was brought under the APA. 

n.4. To the extent Wichita Tribe is
asserting Caddo Nation did not exhaust its administrative remedies, such an
argument is not adequately briefed. Wichita Tribe vaguely asserts Caddo Nation
“could have filed timely administrative appeals of the Wichita Tribe’s and HUD’s
decisions regarding the Project.” Appellees’ Br. at 39. As the Supreme Court has
made clear, however, administrative exhaustion is entirely dependent on statutory
and regulatory requirements. Darby v. Cisneros, 

, 153-54 (1993).
                                                                         (continued...)

                                          -4-
Caddo Nation’s NEPA and NHPA claims are moot. Those claims are moot as

they relate to the 4000 square foot museum, the traditional grass house, and the

grass arbor. There is no indication in the record, however, that the ceremonial

dance grounds, a portion of the History Center project specifically included in

Wichita Tribe’s EA, has been completed. Thus, on the current record, Caddo

Nation’s NEPA and NHPA claims are not moot as to that narrow aspect of the

History Center project. Accordingly, exercising jurisdiction pursuant to 28

U.S.C. § 1291, this court affirms in part, reverses in part, and remands to the

district court for further proceeding consistent with this opinion.

                                  II. ANALYSIS

      Because a ruling in its favor on the matter would fully resolve the appeal,

this court first takes up Wichita Tribe’s assertion that Caddo Nation’s APA-based

NEPA and NHPA claims are barred by tribal sovereign immunity. See Miner

Elec., Inc. v. Muscogee (Creek) Nation, 

, 1009 (10th Cir. 2007)

(holding that tribal sovereign immunity implicates subject matter jurisdiction).



      3
        (...continued)
Absent any indication of what actions Caddo Nation failed to undertake that are
required by statute or regulation, there is nothing to indicate Caddo Nation’s
NEPA and NHPA claims are unexhausted. See 

remaining matters
set out in Wichita Tribe’s appellate brief can only reasonably be construed as
relevant if this court should conclude the amended complaint does not state APA-
based NEPA and NHPA claims. Having concluded the amended complaint does
state such claims, and also having noted that such claims are the only ones that
remain pending on appeal, 

n.2, the remaining contentions are irrelevant.

                                         -5-
The district court correctly rejected this proposition. The History Center project

was funded using a HUD grant. As part of the process of granting such funding,

HUD can “delegate any of [its] functions, powers, and duties . . . as [it] may deem

desirable.” 42 U.S.C. § 3535(d). “[I]n lieu of the environmental protection

procedures otherwise applicable, [HUD] may under regulations provide for the

release of funds for particular projects to recipients of assistance . . . who assume

all of the responsibilities for environmental review, decisionmaking, and action

pursuant to [NEPA], and such other provisions of law as the regulations” may

specify. 42 U.S.C. § 5304(g)(1). The relevant regulations require that a grantee

like Wichita Tribe comply with both NEPA and NHPA. 24 C.F.R. §§ 58.1, 58.4,

58.5, 1003.605. Consistent with this scheme, HUD delegated its obligations

under NEPA and NHPA to Wichita Tribe and Wichita Tribe certified compliance

with both. 4


       4
           Indeed, the EA certifies as follows:

       The [Wichita Tribe] certifies to HUD that Terri Parton, in her
       capacity as President consents to accept the jurisdiction of the
       Federal Courts if an action is brought to enforce responsibilities in
       relation to the environmental review process and that these
       responsibilities have been satisfied. HUD approval of the
       certification satisfies its responsibilities under NEPA and related
       laws and authorities and allows [Wichita Tribe] to use program
       funds.

See 42 U.S.C. §§ 5304(g)(3)(D), 5306(a) (providing together that when a grantee
tribe assumes the pertinent regulatory responsibilities, it must “specify that the
                                                                        (continued...)

                                            -6-
      The APA generally waives the Federal Government’s immunity from a suit

“seeking relief other than money damages and stating a claim that an agency or an

officer or employee thereof acted or failed to act in an official capacity or under

color of legal authority.” 5 U.S.C. § 702. By specifically accepting and assuming

HUD’s rights, duties, and obligations to act in conformity with NEPA and NHPA,

Wichita Tribe waived its sovereign immunity for just the type of APA-based suit


      4
        (...continued)
certifying officer (i) consents to assume the status of a responsible Federal
official under [NEPA or NHPA] . . . and (ii) is authorized and consents on behalf
of the recipient of assistance . . . to accept the jurisdiction of the Federal courts
for the purpose of enforcement of his responsibilities as such an official”).
Wichita Tribe asserts, as a general matter, it is only the Executive Committee, not
the President, that can waive Wichita Tribe’s sovereign immunity. Appellees’ Br.
at 41-42. It specifically recognizes, however, that the waiver in the EA is
effective, even though only signed by the President, to the same extent as a
waiver by the federal government. 

(“As with the federal government,
however, [the waiver of sovereign immunity in the EA] would be effective—if at
all—only if Caddo had complied with the requirements of the APA. Because
Caddo failed to comply with the APA, the argument is meritless.”). As noted
above, however, Caddo Nation brought properly exhausted APA claims in its
amended 

n.3, and those APA claims are the only ones that
remain alive in this 

n.2. Thus, by its own admission, Wichita Tribe’s
argument as to sovereign immunity fails. In any event, the record before this
court does not support the assertion that only the Executive Committee has the
power to waive sovereign immunity. The Wichita Governing Resolution reserves
to the Executive Committee the “power . . . to transact business and otherwise
speak or act on behalf of the Tribes,” but later grants to the President the power
of “general supervision . . . of the Executive Committee” and state the President
“shall perform all duties appertaining to the office.” Based on this language, we
conclude the document does not preclude the President from waiving sovereign
immunity in the manner set out in the EA. Cf. Sanderlin v. Seminole Tribe of
Florida, 

, 1287 (11th Cir. 2001) (holding no waiver by officer when
tribal charter reserved sovereign immunity waiver “pursuant to a resolution duly
enacted by the Tribal Council”).

                                         -7-
at issue in this case. In arguing for a contrary result, Wichita Tribe does not cite

to any relevant precedent. Instead, it merely identifies cases indicating a wavier

of tribal sovereign immunity must be clear and unequivocal. See, e.g., Okla. Tax

Comm’n v. Citizen Band Potawatomi Indian Tribe of Okla., 

, 509

(1991). The statutory and regulatory scheme set out above, however, could not be

more clear: HUD can condition the provision of a grant to an Indian tribe on the

tribe’s acceptance of HUD’s obligation to comply with NEPA and NHPA, an

obligation enforceable via the APA. 5 U.S.C. § 702; 42 U.S.C. §§ 5304(g),

5306(a). Because HUD did so condition the grant to Wichita Tribe, and because

Wichita Tribe affirmatively waived its sovereign immunity in the certification

included in the EA, this court has subject matter jurisdiction over Caddo Nation’s

APA-based NEPA and NHPA claims against Wichita Nation.

      The district court concluded the case was moot because Wichita Tribe had

completed construction of the History Center. This conclusion is only partially

correct. The EA describes the project as constituting four parts: a 4000 square

foot building, a grass house, a grass arbor, and a ceremonial dance ground. The

record definitively demonstrates that the building, grass house, and grass arbor

are complete. 5 In its brief on appeal, Wichita Tribe asserts the “dance ground

aspect was abandoned after the FONSI was published.” Appellees’ Br. at 25-26

n.15. There is nothing in the record, however, to confirm this assertion. Absent

such evidence, this court cannot affirm the dismissal of the NEPA and NHPA

claims on the basis that construction of the History Center project has been

completed.

      Caddo Nation asserts that even those aspects of the History Center project

that are complete present a live controversy. This argument is unconvincing. It is

certainly true that the mere completion of portions of the History Center project

does not necessary render Caddo Nation’s APA-based NEPA and NHPA claims

moot. It is for that very reason Caddo Nation remanded the matter to allow for

the filing of an amended complaint focused on “the operation of the Center or

other activities on the 

. The problem, however, is that

Caddo Nation has not identified any aspect of the operation of the completed

portions of the History Center project that implicates the interests advanced in

NEPA and NHPA.

      Caddo Nation relies on Airport Neighbors Alliance, Inc. v. United States,

(10th Cir. 1996), to support its contention this court could still award

relief. This reliance is misplaced. Airport Neighbors is a NEPA case in which


      5
        (...continued)
(10th Cir. 2000) (“We note . . . that the court is permitted to take judicial notice
of its own files and records . . . .”), abrogated on other grounds by McGregor v.
Gibson, 

(10th Cir. 2001).

                                         -9-
this court found relief might be available to address environmental issues caused

by use of a new airport runway. 

8-29. Caddo Nation did not identify in

its amended complaint any environmental issues relating to the operation of the

History Center. Airport Neighbors makes clear that claims related to construction

are moot once construction is complete:

      [A]lthough the fact that the upgrade of Runway 3–21 has been
      completed renders moot any claim relating to the construction of the
      runway, we still may consider whether Respondents complied with
      NEPA by adequately addressing the environmental impacts resulting
      from the enhanced use of the runway.

9. In its amended complaint, Caddo Nation sought a declaration that

Wichita Tribe violated NEPA and its implementing regulations and NHPA, yet

alleged no environmental (or other) concerns that would result from continued

operations at the History Center. That being the case, Caddo Nation’s APA-based

NEPA and NHPA claims are moot to the extent construction is complete. Caddo

(“‘Ordinarily, a NEPA claim no longer presents a

live controversy when the proposed action has been completed and when no

effective relief is available.’” (quoting Airport 

)). 6


      6
        To the extent Caddo Nation asserts this court can grant it a sufficient
remedy by directing the parties to discuss demolishing those portions of the
History Center project that have been completed, this court concurs with the
district court:

      such a suggestion does not constitute a “remedy” or “other relief”
      within the meaning of the mootness inquiry. If directing the parties
                                                                     (continued...)

                                         -10-
Because Caddo Nation has not sought to enjoin operations at the History Center

or any other specific, tangible activity, there is no live case or controversy as to

those portions of the History Center project that are complete. 7

                                III. CONCLUSION

      For those reasons set out above, all aspects of Caddo Nation’s APA-based

NEPA and NHPA claims are moot, with the singular exception of the aspect of

the claims relating to the ceremonial dance grounds. Accordingly, the district

court is AFFIRMED IN PART, REVERSED IN PART, and this matter is

REMANDED to the district court for further proceeding consistent with this




      6
       (...continued)
      to a controversy to “discuss it” is “other relief,” then no dispute
      would ever be moot because a court would always have that option
      available. That is plainly inconsistent with the existence and nature
      of the mootness doctrine.

District Ct. Order of July 9, 2018, at 6-7. Instead, as Caddo Nation and Airport
Neighbors make clear, NEPA and NHPA claims directed to the construction
aspects of a project are moot when the project is completed.
      7
        This court rejects Caddo Nation’s assertion that its NEPA and NHPA
claims are not moot because it has adduced credible evidence Wichita Tribe plans
to engage in further development in areas adjacent to the History Center. First,
Caddo Nation has never identified any final agency action other than the FONSI
set out in the EA. As noted above, the EA is specifically limited to the History
Center project. Second, Wichita Tribe’s obligation to comply with NEPA and
NHPA, and its concomitant waiver of sovereign immunity, is directly tied to its
receipt of a HUD grant to build the History Center. Caddo Nation has not
identified any basis to conclude any such contemplated development falls within
the ambit of the instant APA-based claims.

argument, Wichita Nation’s Motion for Summary Disposition is DENIED as

moot.
