    Everyone agrees that Hydro Resources, Inc. (“HRI”) must obtain a Safe
    Drinking W ater Act (“SDW A” or “the Act”) permit to mine its property. The
    only question is: from whom? The Environmental Protection Agency (“EPA” or
    the “Agency”), which administers the Act, has chosen to delegate its permitting
    authority in the State of New M exico to the New M exico Environment
    Department (“NM ED”), but with one exception: EPA has not delegated its
    authority to issue permits for mining activities on “Indian lands.” Thinking its
    land hardly qualified as “Indian land” — HRI owns its property in fee, it pays
    county real estate taxes, the land is uninhabited, and it is not inside any Indian
    reservation or otherwise set aside and superintended for Indian use — the
    company proceeded to apply for, and obtain, a permit from NM ED. Initially, EPA
    professed no quarrel with this, and it has never questioned NM ED’s
    -3-
    administration of the Act. But eventually a dispute broke out over the status of
    HRI’s land and, after years of regulatory wrangling, EPA issued a “final land
    status determination” expressing its judgment that HRI’s land qualifies as “Indian
    land.” As a result, EPA ruled, HRI must seek and obtain its SDW A permit from it
    rather than NM ED.
    How did EPA reach this conclusion? By regulation, EPA chose to define
    the term “Indian lands” — the only lands for which it did not cede primary
    permitting authority to NM ED — to be synonymous with “Indian country,” as that
    term is defined by 
    18 U.S.C. § 1151
    . Section 1151, in turn, provides primary
    federal criminal jurisdiction over certain territories: “Indian reservation[s],”
    “dependent Indian communities,” and “Indian allotments.” So it is that, for EPA
    to exercise primary permitting authority in this case, the Agency had to argue that
    the federal government, rather than the State of New M exico, possesses primary
    criminal jurisdiction over HRI’s private property. In this case, EPA took the
    position that HRI’s land is Indian country and subject to federal jurisdiction
    because it is part of a “dependent Indian communit[y]” under § 1151(b).
    But whatever HRI’s land is, it can’t be that. In Alaska v. Native Village of
    Venetie Tribal Government, 
    522 U.S. 520
     (1998), the Supreme Court identified
    two “requirements” of all “dependent Indian communities” under § 1151(b).
    First, “the land in question” must be an “Indian community” in the sense that it
    -4-
    has been explicitly “set aside” by Congress (or the Executive, acting under
    delegated authority) “for the use of the Indians as Indian land.” Id. at 527, 531.
    Second, “the land in question” must be “dependent” in the sense that it is “under
    federal superintendence.” Id. at 527. HRI’s land — the land in question in
    EPA’s final land status determination — is neither of these things.
    Despite this, EPA argued before a panel of this court that we should cast
    our gaze beyond the particular land in question. In the Agency’s view, because
    some sufficiently significant (though unspecified) percentage of neighboring
    lands — what EPA calls “the community of reference” — is Indian country,
    HRI’s land must be considered Indian country, too. In defense of its view, EPA
    pointed to certain of this circuit’s cases, most pre-Venetie, suggesting the
    approach it took. Deeming itself bound by the same authority, a panel of this
    court upheld EPA’s classification of HRI’s land as Indian country. Hydro Res.,
    Inc. v. U.S. EPA, 
    562 F.3d 1249
     (10th Cir. 2009) (“HRI II”).
    HRI responded to all this with a petition for en banc review. The company
    argued that the “community of reference” approach advanced by EPA and certain
    of this circuit’s cases is inconsistent with Venetie. HRI submitted, too, that our
    cases are in conflict with each other — while some follow EPA’s approach, others
    after Venetie have abjured the “community of reference” test, as have decisions in
    -5-
    our sister circuits. Seeking to sort all this out, we granted HRI’s request for en
    banc review.
    Having now heard the case anew, we find ourselves compelled to vacate
    EPA’s final land status determination. EPA’s interpretation cannot be reconciled
    with the Supreme Court’s explanation of § 1151(b)’s plain meaning. Venetie
    explicitly rejected a Ninth Circuit test composed of the very factors used in the
    “community of reference” test employed by EPA and certain of our pre-Venetie
    cases. Neither is the amorphous “community of reference” test compatible with
    the history and structure of the statute we are charged to interpret, or with the
    Supreme Court’s longstanding direction that criminal statutes should be
    interpreted clearly and precisely to afford fair warning of their reach.
    None of this is to say that EPA must tether its SDW A permitting authority
    to a statute defining the scope of the federal government’s criminal jurisdiction
    over Indian lands. Had EPA chosen to define its authority under the SDW A in a
    different way, the result in this case might have been different. But we decide the
    cases as they come to us. And in this case, heeding the Supreme Court’s
    commands in Venetie requires us to grant HRI’s petition for review and vacate the
    Agency’s final land status determination.

    The history of this dispute is long and tangled. Even so, some appreciation
    of its twists and turns is essential. W e begin by examining briefly the history of
    the land in question (Section I.A), the regulatory scheme governing that land and
    the parties before us (Section I.B), the parties’ first lawsuit before this court
    (Section I.C), its subsequent remand to EPA (Section I.D), and the current appeal
    (Section I.E), all before we turn to address our jurisdiction and standard of review
    (Section II) and, at last, the merits of this appeal (Section III).
    A
    The land at issue in this case lies in what is commonly known as the
    “checkerboard” region of northwestern New M exico. See generally Pittsburg &
    M idway Coal M in. Co. v. Yazzie, 
    909 F.2d 1387
    , 1389-92 (10th Cir. 1990). This
    region abuts the southern and eastern boundaries of the Navajo Reservation
    originally created by an 1868 treaty between the United States and the Navajos.
    
    Id. at 1389
    . And a checkerboard it is, marked by alternating parcels of land
    owned by the state, the federal government, the Navajo Nation, individual
    Navajos, and private persons and entities. See 
    id.
     at 1423 app. A (map section
    marked “J”); Appendix. 1
    1
    The Appendix reproduces a map of the Church Rock Chapter and its
    boundaries. The map was prepared as part of the Church Rock Chapter’s Land
    Use Plan and included in the record before the Agency. See R. 16b; R. 40 at B-
    39.
    -7-
    The checkerboard seems to have had its start with the railroad. In the late
    nineteenth century, the federal government granted certain lands in the region to
    railroad companies in an effort to induce construction. “These grants typically
    consisted of alternating one-mile-square parcels on each side of the planned line
    for the railroad tracks . . . .” HRI II, 
    562 F.3d at
    1254 n.3. From this, a
    checkerboard was born, aided and abetted by the fact that other tracts of land in
    this area, though still formally held in the public domain, were occupied by
    Navajos, while still others were being rapidly snapped up by white and M exican
    settlers. Yazzie, 
    909 F.2d at 1390
    .
    And this was just the start of the complications. As Judge Anderson
    explained in his thorough history of the area, by the turn of the twentieth century
    federal officials became concerned that the new settlers were “appropriating the
    limited water holes for themselves.” 
    Id. at 1390
    . So, in an effort to protect the
    Navajo population, President Theodore Roosevelt signed two executive orders,
    E.O. 709 and E.O. 744, in 1907 and 1908, respectively. The combined effect of
    these orders was to add much of the land in this area to the Navajo Reservation.
    
    Id. at 1391
    . At the same time, the President’s orders expressly preserved
    preexisting private property rights, including the railroad land grants. Thus, “the
    extension to the Reservation” further complicated the variegated character of the
    area. 
    Id.
     at 1391 n.6.
    -8-
    Still more checkerboarding followed. It seems the government did not
    intend the area to become a permanent addition to the Reservation. See 
    id.
    Instead, the plan apparently was to allow Indians 2 then living in the area a brief
    period to claim and “receive 160-acre allotments in severalty without interference
    from whites and M exican stockmen.” 
    Id. at 1390
    . After that, any unallotted land
    was to revert from reservation status back to the public domain. See 
    id.
     And this
    is exactly what transpired in 1911 by virtue of another executive order, this one
    issued by President Taft. 
    Id. at 1392
    . Since then, land in this area has changed
    hands many times in still more complicating ways. In 1928, for example,
    Congress appropriated funds for the purchase of some privately held former
    railroad tracts in order that they might be held by the federal government for the
    benefit of the Navajo. HRI II, 
    562 F.3d at
    1254 n.3. M eanwhile, other parcels
    now belong to the New M exico state government or remain in the hands of non-
    Indians.
    HRI’s land falls into this final category. In 1970, the federal government
    sold 160 acres in the southeast quadrant of “Section 8,” Township 16N, Range
    2
    W e recognize that “most tribal members do not refer to themselves as
    generic ‘Indians’ or ‘Native Americans,’ but rather as constituents of particular
    groups, such as Hopi or Cheyenne” or Navajo. Cohen’s Handbook of Federal
    Indian Law, § 3.01 at 134 n.1 (Nell Jessup Newton et al. eds., 3d ed. 2005). W e
    use the general term “Indian” throughout this opinion in light of its use in the
    relevant statutory language and precedents.
    -9-
    16W , to the United Nuclear Corporation. See Appendix. In turn, United Nuclear
    later sold the land to HRI. There are no inhabitants on HRI’s land. Except for
    the brief period from 1907-11, it has not been set aside by Congress for Indians or
    placed under federal superintendence for their benefit. The remaining three
    quadrants of Section 8 land not owned by HRI are still owned in fee by the United
    States. R. 15c App. XI at para. 3. Other adjacent sections include parcels held in
    trust for the Navajo by the United States (Sections 9 and 17) and land owned by
    the State of New M exico (Section 16). See Appendix.
    Section 8 lies within M cKinley County, New M exico. The county seat
    resides in the city of Gallup, “approximately 11 miles southwest of the Section 8
    land.” HRI II, 
    562 F.3d at 1254
    . The state and county exercise jurisdiction over
    private lands throughout the checkerboard area. So, for example, the State of
    New M exico maintains the only road access to Section 8, State Highway 566,
    while M cKinley County shares responsibility with the federal government for
    other roads in the vicinity. HRI II, 
    562 F.3d at 1254
    . The County provides
    essential public services to private lands like HRI’s, including fire, police, and
    emergency services. 
    Id.
     The Gallup/M cKinley County public school system
    offers public education and school transportation for those in the area. 
    Id.
     And
    HRI pays annual property taxes on its land to M cKinley County. 
    Id.

    Section 8 also falls within the boundaries of the Navajo Church Rock
    Chapter. The Chapter is a political and social unit of the Navajo Nation, with its
    boundaries and membership determined by the Tribe. See 
    id. at 1255
    . 3 The
    current boundaries as drawn by the Tribe include tracts owned in fee by the
    United States, privately held lands, and Navajo Nation lands. 
    Id.
     At the same
    time, the Chapter’s boundaries exclude at least one parcel of state land, Red Rock
    State Park, thus creating a sort of “doughnut hole” in the middle of the Chapter.
    See Appendix. W hile most of the land in the Chapter lies north of Interstate 40,
    the Chapter does include a narrow traverse across the Interstate and a small tract
    on the highway’s south side. See 
    id.
    3
    The EPA’s final land status determination states that the “Church Rock
    Chapter was first established in 1927 by the United States as a subdivision of the
    Navajo Nation government, to facilitate local Navajo self-government and to
    foster improved communications between Navajos and federal agencies.” R. 44 at
    8. HRI disputes this conclusion. First, HRI argues that the 1927 date makes no
    sense, because it was a year before the government began repurchasing for Indian
    use much of the land that now comprises the Chapter. Second, HRI argues that
    the record contains no support for the assertion that the federal government
    established the Church Rock Chapter. Upon review of the source cited by EPA, it
    appears HRI may have the better of the argument. W hile the source suggests that
    the federal government played some undefined role in helping to establish Navajo
    chapters beginning in 1927, it does not mention the Church Rock Chapter, let
    alone indicate that the federal government established it. See Robert Young,
    Navajo Yearbook 191 (1958). The record, at least as briefly adduced by the
    parties in this litigation, thus suggests that the Navajo Nation, not the federal
    government, established the Chapter.
    -11-
    The political and social center of the Church Rock Chapter is the Chapter
    House, located in the village of Church Rock, six miles east of Gallup and about
    six miles south of Section 8. See 
    id.
     M uch of the membership of the Chapter
    lives in close proximity to the Chapter House, and Chapter members typically
    visit the Chapter House at least once a month for meetings and social activities
    and services. R. 40 at B-29. At the same time, nearly half of the Chapter’s
    members are employed in Gallup and so travel there frequently, compared to just
    2% who are employed within the Chapter’s boundaries. R. 40 at B-24. The
    Chapter recognizes that private lands within its boundaries are subject to state
    jurisdiction and control, R. 40 at C-16, and the Chapter provides no infrastructure
    or services to HRI’s portion of Section 8, R. 6 at 2. Indeed, a significant portion
    of the territory within the Chapter, including Section 8, consists of “rugged
    mountain ranges, canyons, and highlands” that, according to the Chapter, are “not
    suitable for community or industrial development.” R. 40 at B-40.
    B
    After purchasing its Section 8 land, HRI sought to mine it for uranium. In
    preparation, the company obtained various regulatory permits. Because HRI’s
    proposed mining operations contemplated the use of an underground injection
    system to extract the ore, SDW A regulations required the company to obtain
    -12-
    approval of an underground injection control (“UIC”) plan aimed at mitigating the
    risk of contamination to potential drinking water sources. 4
    W hile EPA is responsible for administering the SDW A, Congress
    anticipated that the states would, at least sometimes, serve as the primary entities
    responsible for reviewing and granting or denying UIC permits. In the SDW A,
    Congress told EPA it could “either approve, disapprove, or approve in part and
    disapprove in part, [each] State’s” application to become the primary UIC
    permitting authority.   42 U.S.C. § 300h-1(b)(2). The Act then went on to direct
    EPA to promulgate certain standards that the state UIC regulatory programs
    would have to meet to achieve this distinction. See 42 U.S.C. § 300h; 
    40 C.F.R. § 144.1
    (e). Exercising these statutory authorities granted to it, EPA some time
    ago set standards for state UIC programs and approved NM ED’s application to
    serve as the primary UIC permitting authority in the State of New M exico, except
    4
    “Underground injection . . . means the subsurface emplacement of fluids
    by well injection . . . .” 42 U.S.C. § 300h(d)(1)(A). Basically, HRI seeks to
    pump water into the ground and circulate that water in order to pull uranium to
    the surface where it can be easily collected. This method is apparently less
    onerous than manually excavating the rock from underground and removing the
    uranium later. R. 15c App. II at 1, 3-4 (“Instead of manually excavating the rock
    from underground as in conventional mining and placing it in large piles on the
    surface, water wells are used, very much like those for a home. Oxygen is added
    to the native ground water from the ore body, and that water is continuously
    circulated until most of the uranium is recovered.”).
    -13-
    with respect to underground injection wells “on Indian lands.” 
    40 C.F.R. §§ 147.1600-147.1601
    .
    It is here the real regulatory complications begin. How do we know when
    underground injection wells lie on “Indian lands”? By regulation, EPA has
    chosen to define the phrase “Indian lands,” when it appears in SDW A regulations,
    to mean “Indian country,” as that term is defined by 
    18 U.S.C. § 1151
    . See 
    40 C.F.R. § 144.3
    . Adopted in 1948, § 1151 is part of the criminal code and
    circumscribes where the federal government or a tribe, rather than a state, may
    exercise primary criminal jurisdiction. At the same time, the statute has been
    used often, as EPA has chosen to use it here, to define the scope of federal
    authority over civil and regulatory matters. See Venetie, 
    522 U.S. at 527
    ; Cohen’s
    Handbook of Federal Indian Law § 3.04[1] (Nell Jessup Newton et al. eds., 3d ed.
    2005) (hereinafter “Cohen (2005)”). 5
    Section 1151 defines “Indian country” as encompassing three categories of
    land:
    5
    W hile statutory criminal jurisdiction has been confined to “Indian
    country” as defined in § 1151, it has been said that Congress enjoys “plenary
    power over Indian affairs,” Venetie, 
    522 U.S. at
    531 n.6, by virtue of Article I,
    Section 8, Clause 3 of the Constitution, which ascribes to Congress exclusive
    authority over “Commerce . . . with the Indian Tribes.” W hether and how far
    Congress’s constitutional authority to authorize federal “Indian country”
    jurisdiction might proceed beyond the limits of § 1151 is not before us in this
    case.
    -14-
    (a) all land within the limits of any Indian reservation under the
    jurisdiction of the United States Government, notwithstanding the
    issuance of any patent, and, including rights-of-way running through
    the reservation,
    (b) all dependent Indian communities within the borders of the
    United States whether within the original or subsequently acquired
    territory thereof, and whether within or without the limits of a state,
    and
    (c) all Indian allotments, the Indian titles to which have not been
    extinguished, including rights-of-way running through the same.
    
    18 U.S.C. § 1151
    .
    Having thus defined the scope of “Indian lands” under its SDW A
    regulations, EPA still faced the question: W ho, if not the state, should enjoy
    primary authority to regulate wells on those lands? The SDW A entrusts primary
    UIC permitting authority to EPA but allows the Agency to delegate that authority
    to tribes, much as it does to states, at least with respect to permit applications
    “within the area of the Tribal Government’s jurisdiction.” 42 U.S.C. § 300j-
    11(b)(1)(B); see also 42 U.S.C. § 300h-1(e). And by regulation, EPA has
    indicated that a “Tribal Government’s jurisdiction” for these purposes may not
    extend beyond “Indian country,” as that term is (once again) defined in § 1151.
    See, e.g., Navajo Nation; Underground Injection Control (UIC) Program; Primacy
    Approval, 
    73 Fed. Reg. 65,556
    -01, at 65,558-65,560 (Nov. 4, 2008) (“EPA
    recognizes that 18 U.S.C. 1151 . . . generally defines the limit of the area over
    which a Tribe may demonstrate authority.”).
    -15-
    In 1994, EPA chose to exercise this authority to delegate primary UIC
    permitting authority to the Navajo Nation for lands within the Navajo
    Reservation, as well as for certain other Navajo allotments and Navajo fee lands.
    HRI, Inc. v. EPA, 
    198 F.3d 1224
    , 1232 (10th Cir. 2000) (“HRI I”). At the same
    time, however, EPA declined to approve the Tribe’s application to assume
    primary UIC permitting authority over all privately held fee lands in the
    checkerboard region where Section 8 resides.

    . It was and is
    undisputed that these lands do not qualify as part of any Indian reservation within
    the meaning of § 1151(a), or as Indian allotments within the meaning of
    § 1151(c). Though the Tribe sought to persuade EPA that the lands nonetheless
    qualify as “Indian country” because, given social and political affinities in the
    area, they are part of a larger “dependent Indian community” within the meaning
    of § 1151(b), EPA rejected this claim. The Agency explained its view that the
    Tribe had “not demonstrated that it has jurisdiction” over the lands in question, R.
    13b at 239 (emphasis in original), adding that, “[b]efore it could determine if a
    parcel of land is part of a dependent Indian community (and therefore is Indian
    country), EPA would need more information about that particular parcel of land.”
    Id. at 238. The Agency thus left open at least the hypothetical possibility that
    there could be “Indian lands” within the checkerboard area over which it, rather
    than the Navajo Nation, might retain primary UIC regulatory authority — at least
    -16-
    until such time as the Tribe could come forward with evidence showing that the
    “particular parcel of land” in question qualified as Indian country under
    § 1151(b).
    C
    It is perhaps unsurprising that such a complex land ownership scheme,
    overlaid by such a complex regulatory scheme, might beget equally complex
    litigation. And so it did when HRI tried to ascertain which regulatory authority
    held the UIC permit it needed. HRI knew that the Tribe didn’t have permitting
    authority over its land, at least not yet. The remaining choices HRI thus
    confronted were EPA or NM ED. Not conceiving of its land as part of a
    “dependent Indian community” within the meaning of § 1151(b), and absent any
    EPA decision holding otherwise, HRI requested a UIC permit from NM ED. For
    their part, New M exico state authorities agreed that HRI’s land wasn’t Indian
    land, reviewed HRI’s UIC application, and in 1989, approved it.
    As part of the permitting process, NM ED sought from EPA a mandatory
    “aquifer exemption” for HRI’s mining activities, because those activities
    contemplated the introduction of contaminants into an aquifer. Generally
    speaking, the SDW A prohibits contamination of underground aquifers. See 42
    U.S.C. § 300h(b). But because certain aquifers “will never be used as sources of
    drinking water, . . . EPA [has] adopted criteria for exempting [them] from SDW A
    -17-
    requirements.” HRI I, 
    198 F.3d at 1233
    . In due course, EPA approved NM ED’s
    requested exemption because, in EPA’s judgment, the aquifer under HRI’s land
    “does not currently serve as a source of drinking water” and “cannot now and will
    not in the future serve as a source of drinking water.” 
    40 C.F.R. § 146.4
     (a) &
    (b); see also HRI I, 
    198 F.3d at 1234
    ; R. 15c App. II at 2 (noting that, even before
    any mining activity, “water quality at the Section 8 site is mineralized with
    naturally-occurring uranium, and uranium decay products . . . exceeding U.S. EPA
    drinking water [standards].”).
    About this time, however, a jurisdictional dispute arose regarding HRI’s
    planned mining operations on Section 8 and on nearby Section 17. The dispute
    proved protracted as state, federal, and tribal authorities wrangled over whether
    HRI’s UIC operations should be regulated by NM ED or EPA. See HRI I, 
    198 F.3d at 1234-35
    . At some point during this back-and-forth, the Navajo Nation
    presented what EPA considered to be “substantial arguments to support its claim
    that Section 8 is within Indian country.” 
    Id. at 1235
     (quoting EPA opinion letter
    of July 14, 1997). Based on these assertions, EPA deemed Section 8’s Indian-
    land status to be “in dispute.” 
    Id.
    Eventually, in the late 1990s, HRI and NM ED sought review of EPA’s
    assessment in this court. HRI argued that its Section 8 land wasn’t a “dependent
    Indian community” within the meaning of § 1151(b), and so primary UIC
    -18-
    permitting authority rested with NM ED, not EPA or the Tribe. 6 For its part, EPA
    asked the court to remand the matter because it still hadn’t reached a final
    decision on the question of Section 8’s status as Indian country. See HRI I, 
    198 F.3d at
    1236 n.6 (quoting EPA Brief). EPA explained its delay by pointing to the
    Supreme Court’s then-recent decision in Venetie, which indicated that to qualify
    as Indian country under § 1151(b) “the land in question” must be set aside for
    Indians and federally superintended. Venetie, 
    522 U.S. at 531
    . In arriving at this
    holding, EPA noted, the Supreme Court expressly rejected a “more textured”
    balancing test adopted by the Ninth Circuit, a test the Ninth Circuit consciously
    modeled on preexisting Tenth Circuit jurisprudence. See State of Alaska ex rel.
    Yukon Flats Sch. Dist. v. Native Vill. of Venetie Tribal Gov’t, 
    101 F.3d 1286
    ,
    1291-93 (9th Cir. 1996) (quoting Pittsburg & M idway Coal M ining Co. v.
    Watchman, 
    52 F.3d 1531
    , 1545 (10th Cir. 1995)). EPA defended its remand
    request by stressing that it hadn’t yet had an adequate chance to “develop a record
    6
    HRI also sought review of EPA’s assertion of jurisdiction over its mining
    activities on Section 17. See HRI I, 
    198 F.3d at 1243-44
    . Unlike its Section 8
    land, HRI owns only the mineral rights for Section 17, while the federal
    government holds the Section 17 land in trust for the Navajos. The panel in HRI I
    held that Section 17 was Indian country under § 1151(a) and thus HRI’s mining of
    that land was subject to EPA’s regulatory jurisdiction. Id. at 1249-54. HRI did
    not seek review of that issue with the en banc court or file a petition for certiorari
    with the Supreme Court. Consequently, all that remains in dispute is HRI’s
    Section 8 land.

    below with the Venetie standard in mind.” HRI I, 
    198 F.3d at
    1236 n.6 (quoting
    EPA Brief at 47).
    Shortly before Venetie, this court in 1995 developed a two-step, multi-
    variable balancing test for identifying “dependent Indian communities” under
    § 1151(b), sometimes called the “Watchman test.” At its “first step,” the test
    required the identification of an “appropriate community of reference.”
    Watchman, 
    52 F.3d at 1543-44
    . W hen identifying an appropriate “community of
    reference,” we said, a court had to consider three factors: (1) “the geographical
    definition of the area proposed as a community,” United States v. Adair, 
    111 F.3d 770
    , 774 (10th Cir. 1997); (2) “the status of the area in question as a community,”
    Watchman, 
    52 F.3d at 1543
    ; and (3) “the community of reference within the
    context of the surrounding area,” 
    id. at 1544
    . W ithin the second factor, the
    Watchman test called on us to inquire whether there is “an element of
    cohesiveness . . . that can be manifested either by economic pursuits in the area,
    common interests, or needs of the inhabitants as supplied by that locality,” and
    consider whether the proposed community qualifies as “a mini-society consisting
    of personal residences and an infrastructure potentially including religious and
    cultural institutions, schools, emergency services, public utilities, groceries,
    shops, restaurants, and the other needs, necessities, and wants of modern life.”
    
    Id. at 1544
    . And within the third factor, we considered which public entity or
    -20-
    entities “provide infrastructure, government, essential services, and employment”
    for the community. Adair, 
    111 F.3d at 775
    .
    All of this, however, was just the beginning. Having identified a
    “community of reference,” our test then sought, at the “second step,” to determine
    whether that community qualified as a dependent Indian community. And this,
    we said, required the balancing of still more factors: “(1) whether the United
    States has retained title to the lands which it permits the Indians to occupy and
    authority to enact regulations and protective laws respecting this territory; (2) the
    nature of the area in question, the relationship of the inhabitants in the area to
    Indian tribes and to the federal government, and the established practice of
    government agencies toward the area; (3) whether there is an element of
    cohesiveness manifested either by economic pursuits in the area, common
    interests, or needs of the inhabitants as supplied by that locality; and (4) whether
    such lands have been set apart for the use, occupancy and protection of dependent
    Indian peoples.” Watchman, 
    52 F.3d at 1545
     (internal quotation marks and
    alterations omitted). Only the first and fourth of these elements, however, added
    entirely new concepts to the mix; the second and third elements overlapped in
    significant measure with elements of the antecedent “community of reference”
    analysis. Even so, Watchman instructed the use of these elements at both steps in
    -21-
    the analysis and held that, if both steps were satisfied, all land inside the
    “community of reference” qualified as “Indian country.” See 
    id.
    In HRI I, a panel of this court acknowledged that Venetie altered this legal
    landscape and that EPA had not yet had a chance to issue a final determination
    about the status of HRI’s land in light of it. Accordingly, the panel held that
    EPA’s analysis of HRI’s Section 8 land wasn’t yet ripe for review and remanded
    the matter to the Agency for a final determination of the legal status of HRI’s
    land. HRI I, 
    198 F.3d at 1237, 1254
    . After reaching this holding, however, the
    panel proceeded “[i]n dicta,” State v. Frank, 
    52 P.3d 404
    , 408 (N.M . 2002), to
    consider Venetie’s possible impact on this circuit’s Watchman test. On the one
    hand, the panel acknowledged that “Venetie may require some modification” to
    our test. 
    198 F.3d at 1248
    ; see also 
    id. at 1254
    . But, on the other hand, the panel
    also suggested that “nothing in Venetie speaks to the propriety of the first element
    of that test — determination of the proper community of reference.” 
    Id. at 1248
    .
    D
    W ith that for guidance, EPA on remand proceeded to invite comments from
    interested parties. Ultimately, the Agency received comments from the State of
    New M exico, M cKinley County, various corporations, and more than one hundred
    Navajo allottees arguing that HRI’s Section 8 land should not be considered part
    of a dependent Indian community. At the same time, the Agency received
    -22-
    comments from the Navajo Nation, the Navajo Church Rock Chapter, and many
    others arguing that the land should be considered Indian country. In addition to
    all this, EPA consulted the Interior Department’s Solicitor’s Office and the
    Navajo Nation.
    At the end of its review, the Agency acknowledged that “[s]everal
    commenters have suggested that the community-of-reference analysis is no longer
    intact.” EPA Land Status Determination, R. 44 at 4. Yet, seeming to take its cue
    from HRI I’s intimation that Venetie had not spoken “directly” to Watchman’s
    threshold community of reference test, EPA concluded that the test survived
    Venetie — at least in the Tenth Circuit, if not elsewhere. 
    Id.
     At the same time,
    the Agency decided that Venetie modified Watchman’s second step, replacing its
    four-part test with a two-part test focused on how much of the “community of
    reference” is set aside for Indians and federally superintended. If some
    sufficiently high, though unspecified, percentage of the “community of reference”
    met these requirements, EPA would treat all land within the community of
    reference as Indian country under § 1151(b). Id. at 11-12.
    Turning to apply its understanding of § 1151(b) to the facts of this case,
    EPA concluded that the Navajo Church Rock Chapter was “the appropriate
    community of reference” at Watchman’s first step because the Chapter functions
    as a “mini-society.” Id. at 8-9. EPA did not, however, pause to consider whether
    -23-
    the appropriate community of reference might be M cKinley County, and it
    considered Gallup as a candidate only briefly in a footnote. Id. at 10 n.64.
    Neither did EPA consider whether Section 8 might be part of no community at all;
    rather, its analysis seemed to presuppose that every piece of land is part of some
    community of reference.
    After having identified what it considered to be the appropriate community
    of reference, EPA then applied Venetie’s set-aside and federal superintendence
    requirements to that community. W hile HRI’s Section 8 land itself was
    indisputably neither set aside for Indian use nor federally superintended, EPA
    reasoned that all of Church Rock Chapter is Indian country because a sufficiently
    high percentage of the land within its boundaries are set aside for Indian use and
    federally superintended. So it is that, by this series of steps, EPA determined that
    Section 8 “is within the dependent Indian community of the Church Rock Chapter
    and, thus, is Indian country.” Id. at 13. And so it is that EPA required HRI to
    file a new UIC permit application with the federal government.
    E
    Again HRI petitioned this court for review. The company argued, much as
    it had in HRI I, that Venetie abrogated the Watchman test on which EPA relied in
    justifying and conducting its threshold “community of reference” inquiry. In
    -24-
    HRI’s view, Venetie said that § 1151(b) requires a court to ask only whether “the
    land in question” is set aside for Indian use and federally superintended, no more.
    The panel, considering itself constrained by HRI I’s suggestion that
    Watchman’s community of reference test survived Venetie, rejected HRI’s
    argument and upheld the agency’s final land status determination. HRI II, 
    562 F.3d at 1261
    . Judge Frizzell, sitting by designation, dissented in part. He
    questioned whether Section 8 is fairly included within the Church Rock
    community of reference, given that it is uninhabited and isolated land that the
    Chapter has deemed “incapable of sustaining a community.” HRI II, 
    562 F.3d at 1269
     (Frizzell, J., concurring in part and dissenting in part). Judge Frizzell also
    questioned the community of reference test, noting that “[a]s long as a Chapter as
    a whole satisfies whatever percentage of federal set-aside and supervision a
    federal court deems necessary, tribal law may itself define the boundaries of
    Indian country outside” reservations. 
    Id. at 1270-71
    . Through this application
    “of our community of reference test,” Judge Frizzell emphasized, “we take an
    unprecedented step. Never before has non-Indian fee land outside the exterior
    boundaries of a reservation or Pueblo been held to be a dependent Indian
    community.” 
    Id. at 1270
    .
    After the panel issued its decision, HRI petitioned for rehearing en banc,
    asking us to tackle the one issue the panel thought it could not — whether
    -25-
    Watchman’s community of reference test remains an appropriate part of § 1151(b)
    analysis after Venetie. In support of its petition, the company suggested HRI I
    had opened a split of authority within this circuit: while HRI I suggested that the
    community of reference survived Venetie, in United States v. Roberts, 
    185 F.3d 1125
     (10th Cir. 1999), a previous panel of this court had analyzed a § 1151(b)
    claim without reference to Watchman’s community of reference analysis, asking
    only Venetie’s two questions. See also Frank, 52 P.3d at 408 (noting the same
    tension in this circuit’s post-Venetie case law). Though reluctant to protract even
    further this already aged dispute, in light of the arguably inconsistent guidance
    offered by different panels of this court we granted HRI’s petition for en banc
    review. 7
    II
    7
    Pending before the court are several motions seeking leave to file amicus
    briefs. Because the movants possess an adequate interest and present arguments
    that are useful to this court, we grant the motions of the Pueblos of Santa Clara,
    Sandia, Isleta, and Zia and the United Nuclear Corporation. W e deny the motion
    of the American Indian Law Professors for leave to file an amicus brief only
    because granting the motion would cause one or more members of this court to
    recuse themselves from the matter. See 16AA Charles Alan W right et al., Federal
    Practice and Procedure § 3975, at 318-19 (4th ed. 2008) (“Some circuits will
    restrict amicus filings in order to avoid disqualifying a member . . . of the en banc
    court . . . .”). The states of Colorado, Kansas, New M exico, Utah, and W yoming
    also filed an amicus brief, which Federal Rule of Appellate Procedure 29(a)
    allows them to do without requesting the leave of this court.
    -26-
    Before we can address the merits of this dispute, we must first attend to
    antecedent questions about our subject matter jurisdiction (Section II.A) and
    standard of review (Section II.B).
    A
    Federal courts do not wield plenary jurisdiction over every slight or suit.
    Instead, our authority is restricted in ways small and large by constitutional and
    statutory design. Because of this, the task of ensuring ourselves of our own
    subject matter jurisdiction “is not a mere nicety of legal metaphysics,” but
    essential to the rule of law in “a free society . . . . The courts, no less than the
    political branches of government, must respect the limits of their authority.” U.S.
    Catholic Conference v. Abortion Rights M obilization, Inc., 
    487 U.S. 72
    , 77
    (1988); see also In re C & M Properties, L.L.C., 
    563 F.3d 1156
    , 1161 (10th Cir.
    2009).
    Before the panel, EPA challenged HRI’s standing under Article III of the
    Constitution, arguing that its final land status determination imposed no
    constitutionally cognizable injury on HRI. After all, EPA said, that determination
    “merely implicates which regulator (NM ED or EPA) will enforce UIC
    regulations,” and does nothing to alter the substantive SDW A threshold HRI or
    anyone else must clear in order to obtain a UIC permit. HRI II, 
    562 F.3d at 1258
    (emphasis in original). In support of its argument, EPA emphasized New
    -27-
    M exico’s representation that its state UIC permitting process “is more stringent in
    some respects than the Federal program,” and the absence of any evidence that
    EPA’s process or permit would involve “more onerous terms than NM ED[’s].”
    EPA’s M erits Brief at 19-20, HRI II, 
    562 F.3d 1249
     (10th Cir. 2009) (No. 07-
    9506).
    Under Article III, federal courts have jurisdiction only to decide “Cases”
    and “Controversies.” U.S. Const. art. III, § 2. One “essential and unchanging
    part of the case-or-controversy requirement” is the concept that the plaintiff must
    have “standing,” which in turn requires the presence of “three elements.” Lujan
    v. Defenders of Wildlife, 
    504 U.S. 555
    , 560 (1992). A party has standing to
    pursue a claim in federal court only if: (1) it “suffered an ‘injury in fact’ — an
    invasion of a legally protected interest which is (a) concrete and particularized,
    and (b) actual or imminent, not conjectural or hypothetical”; (2) that injury is
    “fairly traceable to the challenged action of the defendant” rather than some third
    party not before the court; and (3) that injury is likely to be “redressed by a
    favorable decision.” 
    Id. at 560-61
     (internal quotation marks, alterations, and
    citations omitted).
    -28-
    Before us, EPA has disputed only the first element — injury in fact. 8 The
    Agency’s challenge, however, cannot succeed. Even if, as EPA would apparently
    have us assume, its UIC permitting process is no stricter than New M exico’s, the
    panel opinion in this case correctly explained that “the outlay of funds necessary
    to secure” a second UIC permit from EPA, on top of the one HRI has already
    secured from NM ED, amply qualifies as a concrete and particularized, actual and
    imminent injury. HRI II, 
    562 F.3d at 1259
    . As we have previously explained,
    “the out-of-pocket cost to a business of obeying a new rule of government[,] . . .
    whether or not [there may be] pecuniary loss” associated with the new rule,
    suffices to establish an “injury in fact.” Nat’l Collegiate Athletic Ass’n v.
    Califano, 
    622 F.2d 1382
    , 1386 (10th Cir. 1980). EPA’s final land status
    determination requires HRI to undergo the UIC permit process for a second time
    — this time with the federal authorities — before it can mine its property. There
    is nothing hypothetical or conjectural about that, or about the fact that such a “re-
    do” would impose on HRI some additional administrative costs. M aybe those
    costs wouldn’t break HRI’s bank, but that’s hardly required to constitute a
    8
    EPA hasn’t challenged the remaining elements of constitutional standing
    for good reason. HRI’s claimed injury — having to incur the expenses associated
    with a second UIC application — is directly traceable to EPA’s final land status
    determination. And that injury is fully redressable by a favorable decision of this
    court vacating EPA’s decision as incompatible with the law.
    -29-
    constitutionally cognizable injury. See 
    id. at 1389
     (“Certainly the cost of obeying
    the regulations constitutes injury.”). 9
    B
    Assured of HRI’s constitutional standing to bring this appeal, before
    reaching the merits it remains to ask whether and to what degree we are
    statutorily empowered to review EPA’s decision.
    The SDW A authorizes us to review “final actions” taken by EPA in its
    administration of the statute. 42 U.S.C. § 300j-7(a)(2). The parties before us
    agree that EPA’s final land status determination qualifies as such a final action,
    and we can see no basis on which we might disagree. But though the SDW A
    grants us the power to review EPA’s action in this case, it does not tell us what
    standard of review we should use in doing so. W hen the legislation at hand
    doesn’t supply a standard of review for us to apply, the Administrative Procedure
    Act (“APA”) provides the default, filling the gap and telling us, among other
    things, that we “shall . . . hold unlawful and set aside agency action, findings, and
    9
    HRI notes this court’s previous suggestion that “[c]ompulsion by
    unwanted and unlawful government edict is injury per se.” Califano, 
    622 F.2d 1389
    ; see also 13A Charles Alan W right et al., Federal Practice and Procedure
    § 3531.4, at 249 (3d ed. 2008) (“[I]njury sufficient to support standing may be
    found in subjection to unwanted procedures.”). The panel did not reach or rest its
    standing holding on this ground, however, and neither must we, given that EPA’s
    rulings will indisputably impose some out-of-pocket costs on HRI.

    conclusions, found to be arbitrary and capricious, an abuse of direction, or
    otherwise not in accordance with law.” 
    5 U.S.C. § 706
    (2)(A).
    It is this last phrase — “otherwise not in accordance with law” — most
    directly at issue here. See FCC v. NextWave Pers. Commc’ns Inc., 
    537 U.S. 293
    ,
    300 (2003) (“The Administrative Procedure Act requires federal courts to set
    aside agency action that is ‘not in accordance with law’ — which means, of
    course, any law, and not merely those laws that the agency itself is charged with
    administering.” (citation omitted)). EPA’s final land status determination
    represents the Agency’s interpretation of its earlier regulations affording NM ED
    primary authority to regulate UIC wells in New M exico “except on Indian lands,”
    
    40 C.F.R. §§ 147.1600-147.1601
    , and then defining “Indian lands” to mean
    “Indian country” as that term is used in 
    18 U.S.C. § 1151
    , 
    id.
     § 144.3. It is by
    dint of these regulatory choices that, in the end, EPA faced the purely legal task
    of interpreting § 1151 in its final land status determination. And it is by dint of
    this that we must ask whether EPA’s interpretation of § 1151 is or is not in
    accordance with the statute.
    Of course, courts afford considerable deference to agencies interpreting
    ambiguities in statutes that Congress has delegated to their care, see Chevron,
    U.S.A., Inc. v. Natural Res. Def. Council, Inc.,

    590 F.3d 849
    , 850-51 (10th Cir. 2009). Courts do not, however, afford the same deference
    to an agency’s interpretation of a statute lying outside the compass of its
    particular expertise and special charge to administer. See M etro. Stevedore Co. v.
    Rambo, 
    521 U.S. 121
    , 137 n.9 (1997) (no deference given to agency interpretation
    of statute, in part, because the agency was not “charged with administering” it);
    Adams Fruit Co. v. Barrett, 
    494 U.S. 638
    , 649 (1990) (“A precondition to
    deference under Chevron is a congressional delegation of administrative
    authority.”); see also Crandon v. United States, 
    494 U.S. 152
    , 174 (1990) (Scalia,
    J., concurring in the judgment) (“The law in question, a criminal statute, is not
    administered by any agency but by the courts.”).
    Section 1151 quite clearly does not fall within EPA’s particular expertise or
    charge to administer. It is not a statute specially involving environmental
    regulation, but one all and only about the geographic parameters of federal and
    tribal criminal prosecutorial authority. Even so, we need not decide whether
    EPA’s interpretation of the statute is entitled to deference because, throughout the
    proceedings before the panel and now the en banc court, EPA itself hasn’t
    claimed any entitlement to deference. In these circumstances, when the agency
    -32-
    doesn’t ask for deference to its statutory interpretation, “we need not resolve the
    . . . issues regarding deference which would be lurking in other circumstances,”
    Estate of Cowart v. Nicklos Drilling Co., 
    505 U.S. 469
    , 477 (1992), and so may
    proceed to review EPA’s interpretation of § 1151(b), as the Agency would have
    us and the panel did, de novo. 1 0
    10
    Though claiming no entitlement to deference for its legal interpretation
    of § 1151(b), EPA does seek deference for its factual findings in applying its
    interpretation of the statute to this case. See 
    5 U.S.C. § 706
    (2)(E) (establishing
    “substantial evidence” review); Allentown M ack Sales & Serv., Inc. v. NLRB, 
    522 U.S. 359
    , 366 (1998). As will be apparent in the analysis that follows, however,
    only purely legal questions, not factual ones, are in dispute before us.
    The principal dissent agrees that EPA is not entitled to Chevron deference,
    but argues that the Agency deserves Skidmore deference. Principal Dissent at 5
    n.2. Of course, an agency’s interpretation of a statute merits deference under
    Skidmore only in “proportion[] to its ‘power to persuade.’” United States v. M ead
    Corp., 
    533 U.S. 218
    , 235 (2001) (quoting Skidmore v. Swift & Co., 
    323 U.S. 134
    ,
    140 (1944)); see also 
    id. at 250
     (Scalia, J., dissenting) (Skidmore deference is a
    “statement of the obvious: A judge should take into account the well-considered
    views of expert observers.”). W hether or not Skidmore compels us to do so, we
    certainly seek in this opinion to take into account EPA’s considered views. But
    we decline to decide the question whether we are obliged by Skidmore to afford
    even this modicum of deference, for a few reasons. First, EPA has not sought
    Skidmore deference, and when a party chooses not to pursue a legal theory
    potentially available to it, we generally take the view that it is “inappropriate” to
    pursue that theory in our opinions. United States v. Int’l Bus. M ach. Corp., 
    517 U.S. 843
    , 855 (1996); see also Estate of Cowart, 
    505 U.S. at 476-77

    W ith this much resolved, we finally reach the merits. The dispute here is a
    purely legal one: Does the Watchman community of reference test remain viable
    following the Supreme Court’s decision in Venetie? EPA argues it does; HRI
    says it does not.
    EPA reads § 1151(b)’s three operative words, “dependent Indian
    communities,” to require a two-step, multi-factor balancing test. First, and
    following Watchman, EPA says we must identify an appropriate “community of
    reference” by weighing three factors in balance: (1) the geographic definition of
    the proposed community; (2) the status of the area in question as a community;
    and (3) the community in the context of the surrounding area. W ithin the second
    of those factors, and again following Watchman, EPA says we must inquire
    10
    (...continued)
    recognition of our dependence on the adversarial process to test the issues for our
    decision and from concern for the affected parties to whom we traditionally
    extend notice and an opportunity to be heard on issues that affect them. Second,
    Skidmore deference traditionally has been justified, at least in part, on an
    assumption that the agency in question has “specialized experience and broader
    investigations and information available to” it than do judges. M ead, 
    533 U.S. at 234
     (internal quotation marks omitted). EPA has claimed, however, no
    comparative experience or expertise over us in rendering a legal interpretation of
    a criminal statute that Congress has never charged the Agency to administer and
    which we have long experience applying. Third, the principal dissent offers no
    indication what impact Skidmore deference makes to its analysis. If it makes no
    difference, then deciding the question is just an exercise in dicta. But if it does
    make a difference, then presumably the dissent would agree with us that, at least
    if viewed de novo, EPA’s final land status determination is contrary to law.
    -34-
    whether there is “cohesiveness that can be manifested either by economic pursuits
    in the area, common interests, or needs of the inhabitants as supplied by that
    locality,” and consider “whether the community is more than an economic pursuit,
    and whether it qualifies as a mini-society consisting of personal residences and an
    infrastructure potentially including religious and cultural institutions, schools,
    emergency services, public utilities, groceries, shops, restaurants, and the other
    needs, necessities, and wants of modern life.” Land Status Determination at 5
    (internal alterations and quotation marks omitted). And within the third factor,
    EPA says, we must also ask “which government or governments provide the
    infrastructure and essential services for the community.” Id. at 6. In EPA’s view,
    none of the analysis to this point is affected by Venetie.
    Having balanced all these competing considerations to identify some
    “community of reference,” EPA moves to the second Watchman step, which it
    does view as modified by Venetie. Before Venetie, the Watchman test sought to
    determine whether a community of reference qualified as a dependent Indian
    community by considering four factors: (1) whether and to what degree the
    United States has retained title to the lands in the community, (2) the nature of the
    area and the relationship of the inhabitants in the area to Indian tribes and to the
    federal government, (3) whether there is “an element of cohesiveness . . .
    manifested either by economic pursuits in the area, common interests, or needs of
    -35-
    the inhabitants as supplied by that locality”; and (4) “whether such lands have
    been set apart for the use, occupancy and protection of dependent Indian
    peoples.” Watchman, 
    52 F.3d at 1545
    . EPA suggests that, after Venetie, the
    second and third of these factors are no longer operative, and that the first and
    fourth essentially track Venetie’s set-aside and federal superintendence
    requirements. Accordingly, EPA submits, if some sufficiently high (though
    unspecified) percentage of the community of reference is set aside for Indians and
    federally superintended, then all the land inside that community should be treated
    as Indian country regardless whether any particular tract is set aside and
    superintended. W eighing all the foregoing considerations, EPA argues that HRI’s
    Section 8 land, though itself neither set aside nor superintended for Indians, is
    Indian country nonetheless because it lies within the Church Rock Chapter
    community of reference and, by the Agency’s calculation, enough of that land is
    set aside and superintended for Indians.
    For its part, HRI submits that Venetie leaves no room for EPA’s reading of
    § 1151(b). After Venetie, HRI urges, the appropriate § 1151(b) test asks only two
    straightforward questions: (1) Has Congress explicitly set aside the land in
    question for Indian use? (2) Does the federal government superintend the land in
    question? Unless the answer to both questions is “yes,” the land in question is
    not within a dependent Indian community. HRI stresses that Venetie expressly
    -36-
    rejected the Ninth Circuit’s § 1151(b) test, a test that was consciously patterned
    on this court’s pre-Venetie jurisprudence and employed the same factors found in
    the Watchman community of reference test. In addition, HRI submits that the
    fact-intensive and multi-factored community of reference balancing test leaves the
    scope of federal criminal jurisdiction impermissibly uncertain and unpredictable,
    contravening the Supreme Court’s direction in Venetie and its repeated
    admonitions elsewhere that criminal statutes merit more concrete and precise
    constructions.
    W e are constrained to agree with HRI. W e hold that Watchman’s
    community of reference test did not survive Venetie and that dependent Indian
    communities under § 1151(b) consist only of lands explicitly set aside for Indian
    use by Congress (or its designee) and federally superintended. W e reach this
    result in light of Venetie’s exposition of the statute’s plain meaning (Section
    III.A), the statute’s history (Section III.B), and the statute’s structure (Section
    III.C), and in doing so we bring the law of this circuit in line with the recent
    decisions of our sister circuits (Section III.D).
    A
    In Venetie, the Supreme Court explained that “dependent Indian
    communities” under § 1151(b) embrace “a limited category of Indian lands that
    are neither reservations nor allotments” encompassed by § 1151(a) and (c),
    -37-
    respectively. 522 U.S. at 527. The Court then identified two necessary
    “requirements” for lands falling into § 1151(b)’s “dependent Indian communities”
    category, explaining that, much like reservations or allotments, “first, they must
    have been set aside by the Federal Government for the use of the Indians as
    Indian land; second, they must be under federal superintendence.” Id.
    W hat does it mean for the federal government to set aside land for Indian
    use and to superintend it? The Court noted that the set-aside requirement means
    that there must be “some explicit action by Congress (or the Executive, acting
    under delegated authority) . . . to create or to recognize” the “land in question” as
    part of a federally recognized and dependent Indian community. 522 U.S. at 531
    n.6. Through an Act of Congress or some equally explicit executive action, then,
    the federal government must identify the land as “set apart for the use of the
    Indians as such.” Id. at 529 (internal quotation marks omitted) (emphasis in
    original). So, for example, land simply conveyed by Congress to individual
    Indians or tribes that they are then “free to use . . . for non-Indian purposes” or
    sell as they wish does not qualify. Id. at 533. W hile groups of Indians may very
    well live on such lands in socially and politically discrete communities, they do
    not live in “Indian country” because the land in question has not been explicitly
    set aside by Congress for use as a “dependent Indian community.” The
    superintendence requirement means that the federal government currently must be
    -38-
    “actively controll[ing] the lands in question, effectively acting as a guardian for
    the Indians.” Id. This requirement, too, necessarily excludes lands that the
    government has conveyed without restriction to Indians or others because such
    lands do not implicate any sense of “guardian[ship],” “wardship[,] or trusteeship.”
    Id. (internal quotation marks omitted).
    The set-aside and superintendence requirements, the Court explained,
    derive from the statute’s plain language — “dependent Indian communities.” The
    set-aside requirement “ensures that the land in question is occupied by an ‘Indian
    community.’” Id. at 531. That is, the boundaries of the Indian community are
    demarcated by and delimited to those lands that are explicitly set aside by
    legislation or executive action for Indian use. The federal superintendence
    requirement “guarantees that the Indian community is sufficiently ‘dependent’ on
    the Federal Government that the Federal Government and the Indians involved,
    rather than the States, are to exercise primary jurisdiction over the land in
    question.” Id.
    In our case, it is undisputed that HRI’s Section 8 land hasn’t been explicitly
    set aside by Congress (or the Executive) for Indian use since the brief period
    when it was appended to the Navajo Reservation nearly a century ago. See supra
    Section I.A. It is likewise undisputed that the land isn’t under federal
    superintendence, and hasn’t been since the government sold it in 1970. See id.
    -39-
    M cKinley County and the State of New M exico provide all essential public
    services to HRI’s Section 8 land, including roads, law enforcement, and
    emergency and school services. The Navajo Church Rock Chapter recognizes that
    private lands within its boundaries, like HRI’s, are subject to state jurisdiction
    and control. And state authorities have long assessed tax on HRI’s property.
    Under Venetie’s interpretation of § 1151(b), it would seem unavoidable that the
    land in question is not Indian country.
    Of course, EPA seeks to avoid just this conclusion by expanding the focus
    from HRI’s particular tract to a wider “community of reference.” According to
    the Agency, only after ascertaining some appropriate community of reference, by
    balancing various social, political, and geographic factors, should one then turn to
    the questions prescribed by the Supreme Court in Venetie, asking whether some
    significant percentage of the community of reference is set aside for Indian use
    and federally superintended.
    This misreads Venetie. The Supreme Court did not direct its set-aside and
    superintendence inquiries toward some abstract “community of reference.”
    Instead, the Court told us (repeatedly) to ask whether the “land in question” is
    explicitly set aside for Indian use and federally superintended. See, e.g., Venetie,
    
    522 U.S. at 530, 531, 533
    . Before us, the only land in question in EPA’s
    challenged final land status determination is HRI’s segment of Section 8. And so
    -40-
    it is only that land that is subject to, and the focus of, Venetie’s set-aside and
    superintendence requirements.
    Tellingly, EPA adopted just this approach to § 1151(b) before HRI I, when
    it considered the Navajo Nation’s request for SDW A authority over private lands
    in the checkerboard area. See supra Section I.B. EPA rejected the Navajo
    Nation’s request, explaining that “[b]efore it could determine if a parcel of land is
    part of a dependent Indian community (and therefore is Indian country), the
    Agency would need more information about that particular parcel of land.” R.
    13b at 238. EPA itself, then, once focused its § 1151(b) analysis on the
    “particular parcel of land” in question. And it seemingly came to eschew this
    approach in favor of the community of reference test only after the panel in HRI I
    suggested in dicta that it should. 1 1
    Of course, EPA now tells us that focusing narrowly on the status of the
    “land in question” fails to give full vent to the statutory term “communities.” The
    Agency stresses that § 1151(b) speaks of “dependent Indian communities,” not
    parcels of land. And the Agency submits that, while Venetie defined the statutory
    11
    It is notable, too, that post-Venetie another arm of the government has
    taken the position, in a criminal matter before this court, that the proper focus is
    on the particular piece of land in question, explaining that “[f]ederal jurisdiction
    is absent over crimes which occur on land which has transferred from Indian
    ownership to non-Indian ownership.” Brief of the United States at 7, United
    States v. Arrieta, 
    436 F.3d 1246
     (10th Cir. 2006) (Nos. 04-2350, 05-2010).
    -41-
    terms “dependent” and “Indian,” it did not consider “community,” the final
    statutory term. The dissents offer this same critique. See, e.g., Principal Dissent
    at 18; Separate Dissent at 2.
    This, too, is in error. The Venetie Court did address the term “community,”
    and did so in light of the statutory terms modifying it. The Court expressly held
    that “dependent Indian communities” are composed of those lands Congress (or
    the Executive, by delegation) has explicitly set aside and superintended for Indian
    use. As the Court clearly explained, “[t]he federal set-aside requirement ensures
    that the land in question is occupied by an ‘Indian community.’” Venetie, 522
    U.S. at 531 (emphasis added). And the federal superintendence requirement, the
    Court emphasized, “guarantees that the Indian community is,” in turn,
    “sufficiently ‘dependent’ on the Federal Government that” it should be subject
    primarily to federal, not state, jurisdiction. Id. (emphasis added).
    In adopting the approach it did, moreover, the Court rejected the idea that
    the boundaries of a federally dependent Indian community should be determined
    by a sort of judicially administered census study of the nature of “the Indian tribe
    inhabiting” the area. Id. at 530 n.5. The right question, the Court held, is instead
    whether Congress has taken some action to designate and maintain the land in
    question for Indian use. It is Congress’s action alone that demarcates the
    boundaries of a dependent Indian community. Id.; see also United States v.
    -42-
    M cGowan, 
    302 U.S. 535
    , 538 (1938) (“Congress alone has the right to determine
    the manner in which this country’s guardianship over the Indians shall be carried
    out.”); cf. Rosebud Sioux Tribe v. Kneip, 
    430 U.S. 584
    , 586 (1977) (“In
    determining whether . . . Reservation boundaries were subsequently diminished[,]
    . . . [t]he underlying premise is that congressional intent will control.”).
    In this way, the Court explained, the federal set-aside and superintendence
    requirements respect and give meaning to an important feature of our
    constitutional order — namely, “the fact that because Congress has plenary power
    over Indian affairs, see U.S. Const. art. I, § 8, cl. 3, some explicit action by
    Congress (or the Executive, acting under delegated authority) must be taken to
    create or to recognize Indian country.” Venetie, 
    522 U.S. at
    531 n.6. W hile
    social or political communities of Indians can exist anywhere in our country, and
    surely do in a great many places outside Indian country, federally “dependent
    Indian communities” exist only where and when Congress has said so.
    Simply put, Venetie held that Congress — not the courts, not the states, not
    the Indian tribes — gets to say what land is Indian country subject to federal
    jurisdiction. It is long settled that Congress does so by declaring land to be part
    of a reservation, or by authorizing its distribution as Indian allotments. And so it
    is the case that Congress must take some equally “explicit action . . . to create or
    to recognize” dependent Indian communities. 
    Id.
     W hen seeking to identify a
    -43-
    § 1151(b) “dependent Indian community,” we must ask whether Congress has
    explicitly set aside the “land in question” for Indian use and put it under federal
    superintendence. If Congress hasn’t declared the land set aside for the
    establishment of a federally dependent Indian community, we are powerless to do
    so ourselves. 1 2
    Applying these principles in Venetie, the Supreme Court held that none of
    the 1.8 million acres of land granted by Congress in fee to the Neets’aii Gwich’in
    Indians in Alaska constituted a § 1151(b) “dependent Indian community.” Id. at
    523-24. It was undisputed that these lands were home to what EPA (and the
    dissents) would consider to be distinct Indian “communities of reference.” After
    all, robust and well-defined Indian villages occupied the land. See Venetie, 
    101 F.3d at 1300
    . Despite such social, political, and geographic affinities, the
    Supreme Court held that a § 1151(b) “dependent Indian community” didn’t exist
    12
    The principal dissent errs when it suggests that under our reading of
    Venetie “title alone is determinative of whether a parcel of land is ‘Indian
    country’ under § 1151(b).” Principal Dissent at 11. The test we adopt at
    Venetie’s direction focuses on set-aside and superintendence, not title. W hile the
    results of the principal dissent’s imagined title test would surely sometimes
    coincide with Venetie’s set-aside and superintendence test, the two are distinct. It
    is, after all, possible that Congress might set aside and guarantee federal
    superintendence for privately titled land, much as it holds certain privately titled
    lands within reservations to be Indian country. See infra Section III.B (discussing
    a 2005 law treating privately titled land within pueblos as Indian country). W hat
    the constitutional limits may be to Congress’s authority to declare land titled to
    non-Indians to be part of Indian country is not before us. See supra note 5.
    -44-
    on any portion whatsoever of the 1.8 million acres of tribal lands because none of
    that land was congressionally set aside or superintended for Indian use. And that
    was because, when it passed the Alaska Native Claims Settlement Act
    (“ANCSA”), Congress deliberately revoked all existing Indian reservations in
    Alaska “set aside by legislation or by Executive or Secretarial Order for Native
    use” and granted tribal corporations fee title to those lands. Venetie, 
    522 U.S. at 532
     (quoting 
    43 U.S.C. § 1618
    (a)). In taking this step, Congress contemplated
    that the tribes could sell any or all of the lands to non-Indians, and could make
    use of them as they wished for any purpose, Indian or non-Indian, without federal
    approval. “In no clearer fashion,” the Supreme Court explained, “could Congress
    have departed from its traditional practice of setting aside Indian lands.” 
    Id.
    W here there is no congressionally approved set-aside for Indian use, and no
    federal superintendence, the Court underscored, there can be no dependent Indian
    community for purposes of § 1151(b). 1 3
    13
    The principal dissent emphasizes that Venetie considered the status of
    the Tribe’s 1.8 million acres of ANCSA land, though the dispute originally arose
    when the Tribe claimed taxing authority over a small strip of land on which the
    State of Alaska planned to build a school. Apparently the principal dissent
    believes this suggests that the Court implicitly thought of all 1.8 million acres of
    ANCSA land as the appropriate “community of reference”; that is, the Court
    really used a community of reference analysis, it just forgot or failed to say so.
    See Principal Dissent at 18-19. Nothing of the kind took place. Before the Ninth
    Circuit, the Tribe categorically claimed “inherent authority to tax activities
    occurring” anywhere “within its [ANCSA] territory.” Venetie, 
    101 F.3d at 1290
    .
    (continued...)
    -45-
    The Watchman community of reference test is inconsistent with this
    direction. Instead of asking whether Congress (or the Executive, through
    delegated authority) has taken some explicit action to set aside the land in
    question and whether the federal government superintends that land, it first
    conducts a threshold inquiry involving multiple competing factors that have no
    basis in Venetie or the text or history of § 1151(b). 1 4 Only after conducting this
    inquiry does the community of reference test turn to Venetie’s prescribed set-aside
    and superintendence questions. And even then the community of reference test
    asks only about the degree and extent to which some other, larger area is set aside
    13
    (...continued)
    The Ninth Circuit agreed, holding that the Tribe enjoyed such taxing authority
    throughout the ANCSA territory. By dint of that holding, all 1.8 million acres
    were in dispute when the case came before the Supreme Court. The Court did not
    explicitly, implicitly, or otherwise hold that the whole 1.8 million acres, or any
    portion of it, qualified as an appropriate community of reference. Instead, the
    Court did what it instructed other courts facing § 1151(b) cases to do: it simply
    and straightforwardly analyzed whether the land in question in the litigation at
    hand — all 1.8 million acres of the Tribe’s ANCSA land — was set aside or
    superintended. And it held that none of that land met those requirements.
    14
    Indeed, for EPA’s understanding of § 1151(b) to be correct, the statute
    would have to read very differently than it does, perhaps something like this:
    “All land must be part of some community of reference that is sufficiently
    cohesive economically and socially to be a mini-society. If the land in question is
    part of a community of reference that contains a sufficiently high percentage of
    Indian people and lands set aside for Indians and federally superintended, it is
    Indian country.” W hat the statute actually says, of course, is that Indian country
    includes dependent Indian communities — that is, land that has been federally set
    aside for use by an “Indian community” that remains “dependent” on the federal
    government through its superintendence. See Venetie, 
    522 U.S. at 530-31
    .
    -46-
    and superintended. In this way, EPA’s test effectively “reduc[es] the federal set-
    aside and superintendence requirements to mere considerations” — something
    Venetie expressly warned us against. 522 U.S. at 531 n.7.
    In this same way, the community of reference test also disregards and
    regularly overrides Congress’s plenary authority in charting the extent of Indian
    country. Applying the test here, EPA held HRI’s land to be Indian country even
    though Congress has not explicitly set aside the land for Indian use and the most
    recent federal action with respect to this land was an executive order in 1911
    removing it from Indian country. See supra Section I.A. It seems to us that, just
    as in Venetie, there could be “no clearer fashion” in which the federal government
    could have extinguished the Indian country status of HRI’s land. Venetie, 
    522 U.S. at 532
    .
    By disregarding Congress’s authority, the community of reference test
    contemplates the possibility that even land never set aside by Congress for
    Indians can become Indian country simply because of its proximity to other lands
    that are federally set aside and superintended. This is so despite the fact that
    neither EPA nor the principal dissent has pointed us to a single case in the history
    of the Supreme Court or this court reaching such a result. Consider what happens
    when a tribe unilaterally redefines its borders to take in just a bit more land (like,
    say, the state park at the center of the Church Rock Chapter, or strips of private
    -47-
    land currently outside but along the edges of the Chapter). See Appendix.
    Assuming the social and political characteristics of this expanded community of
    reference remain more or less constant, land that once wasn’t Indian country
    becomes Indian country by tribal preference or judicial decree rather than
    congressional action.
    Neither does the community of reference test’s disregard for Congress’s
    authority work only to expand Indian communities. It can operate just as well the
    other way around — and would surely do so increasingly as time wears on and
    non-Indian communities encroach on Indian lands. W hat would happen, for
    example, if Gallup grows and dilutes adjacent Indian populations, so that the
    Chapter might no longer be said to constitute its own independent “mini-society,”
    but only part of a greater Gallup “community of reference”? Presuming that this
    new greater Gallup community of reference wouldn’t include a sufficient
    percentage of set-aside and superintended land, no land within its limits would
    constitute “Indian country” under § 1151(b). Under EPA’s approach, land
    expressly set aside for Indian use and superintended by the federal government
    could and would lose its status as Indian country whenever social and political
    boundaries shift — and all this would happen even in the face of express and
    -48-
    contrary congressional direction.1 5 Venetie ties the jurisdictional determination to
    the proper hitch: the will of Congress. The same cannot be said of the
    community of reference test. 1 6
    Any remaining question about the vitality of Watchman’s community of
    reference test is answered by the fact that it would require us to revive the same
    15
    This result, virtually inevitable under the community of reference test,
    sits uneasily with the Supreme Court’s direction that the diminishment of
    reservations under § 1151(a), like additions to them, is Congress’s prerogative
    alone. See, e.g., Solem v. Bartlett, 
    465 U.S. 463
    , 470 (1984) (“The first and
    governing principle is that only Congress can divest a reservation of its land and
    diminish its boundaries.”); 
    id. at 471-72
     (treating history of land after enactment
    of a statute allegedly effecting reservation diminishment as “relevant” only to
    “decipher Congress’ intention,” as an “additional clue as to what Congress
    expected would happen”); Rosebud Sioux Tribe, 
    430 U.S. at
    588 n.4 (“The focus
    of our inquiry [in reservation diminishment cases] is congressional intent.”);
    Yazzie, 
    909 F.2d at 1393
     (“Congress must clearly evince the intent to reduce
    [reservation] boundaries.”).
    16
    The dissents offer no response to this except to suggest that Venetie
    permits us to ask about the “degree” or “extent” of federally set aside and
    superintended land in the proximate area, relying on footnote 7 of the Court’s
    opinion. Principal Dissent at 20 (quoting Cohen (2005) § 3.04[2][c][iii], at 194).
    But rather than support the dissent’s view, the cited footnote does just the
    opposite. The footnote was expressly aimed at rejecting the Ninth Circuit’s use
    of the factors that form the basis of the community of reference test, calling them
    “extremely far removed” from the statute’s language, history, and mandate.
    Venetie, 522 U.S. at 531 n.7. The Court indicated that the Ninth Circuit’s
    examination of the “degree” or “extent” of set-aside and superintended land in the
    general area were “more relevant” inquiries, but the Court did not endorse this
    aspect of the Ninth Circuit’s approach either. Id. Instead, in formulating its own
    test the Court repeatedly held that dependent Indian communities constitute only
    those lands explicitly set aside by Congress for Indians and superintended by the
    government for their benefit. See, e.g., id. at 527 (stating that the land “must
    have been set aside” and “must be under federal superintendence” (emphasis
    added)).
    -49-
    factors the Supreme Court rejected in Venetie. Before the case reached the
    Supreme Court, the Ninth Circuit looked to this circuit’s then-governing
    precedent for guidance in determining whether the land in question before it
    constituted Indian country under § 1151(b). In fact, the Ninth Circuit applied a
    six-factor test that it called “virtually identical” to the second step of our
    Watchman analysis. Venetie, 
    101 F.3d at 1294
    ; see 
    id. at 1291-92
    . The Supreme
    Court, of course, proceeded to reject this “textured” balancing test. Venetie, 
    522 U.S. at
    531 n.7. In particular, the Court criticized reliance on three factors —
    “the nature of the area,” “the relationship of the area inhabitants to Indian tribes
    and the federal government,” and “the degree of cohesiveness of the area
    inhabitants” — as “extremely far removed from” the more concrete set-aside and
    superintendence requirements. 
    Id.
    As we have noted previously, many of the same factors appear in both steps
    of the Watchman analysis. See supra Section I.C. And the three specific factors
    the Supreme Court held impermissible in Venetie are among these reappearing
    factors. Put more pointedly, the factors Venetie expressly rejected are found not
    just in Watchman’s second step; they also form the backbone of Watchman’s first
    step: defining the community of reference. For example, considering the “status
    of the area in question,” as EPA did in its community of reference analysis, Land
    Status Determination at 5, is no different from looking at the “nature of the area,”
    -50-
    a consideration the Supreme Court rejected in Venetie. 522 U.S. at 531 n.7.
    Searching for “the existence of an element of cohesiveness,” as EPA did, Land
    Status Determination at 5, is indistinguishable from seeking to discern “the
    degree of cohesiveness of the area inhabitants,” which the Supreme Court held
    impermissible. Venetie, 
    522 U.S. at
    531 n.7. And focusing “on which
    government or governments provide the infrastructure and essential services for
    the community,” as EPA would have us do, Land Status Determination at 6,
    necessarily requires consideration of “the relationship of the area inhabitants to
    Indian tribes and the federal government,” again something Venetie ruled out-of-
    bounds. 522 U.S. at 531 n.7. In EPA’s application of Watchman’s community of
    reference test, then, the three factors Venetie discredited reemerge, like a phoenix,
    from their own demise. And in some ways, the community of reference test
    favored by EPA is even more problematic than the Ninth Circuit’s approach. At
    least in the Ninth Circuit’s test the three factors rejected by the Supreme Court
    were balanced in fair competition against the set-aside and superintendence
    requirements. In EPA’s application of Watchman’s community of reference test,
    the rejected factors actually receive a promotion to an outcome-determinative
    threshold inquiry. The Agency offers us no credible explanation how we might
    -51-
    lawfully revive, and then elevate, the very same factors the Supreme Court has
    expressly rejected. 1 7
    B
    The Venetie Court didn’t create its § 1151(b) test out of whole cloth, but
    consciously grounded its test in the language and history of the statute. On the
    latter score, the Court noted that subsection (b)’s use of the phrase “dependent
    Indian communities” was designed to codify language from the Supreme Court’s
    decisions in United States v. Sandoval, 
    231 U.S. 28
     (1913), and United States v.
    M cGowan, 
    302 U.S. 535
     (1938). See Venetie, 
    522 U.S. at 528-31
    ; see also
    
    18 U.S.C. § 1151
     History; Ancillary Laws and Directive Notes (“Definition is
    based on latest construction of the term by the United States Supreme Court in
    U.S. v. M cGowan following U.S. v. Sandoval.” (citations omitted)). For that
    reason, Venetie examined and relied on these earlier decisions to give content and
    meaning to subsection (b), recognizing that when a legal concept like this “is
    17
    Neither do the dissents. Instead, the principal dissent proposes a new
    community of reference test different from the one this court used in Watchman
    or EPA used in its final land status determination. The principal dissent would
    still apparently uphold EPA’s determination, though, rather than remand the case
    for reconsideration under its newly formulated version of the community of
    reference test. And it would do so even though its proposed test arguably might
    require additional fact finding by the Agency. Perhaps this is because, while the
    details are slightly changed, the essence of the test is not. Like the Watchman test
    EPA employed, the principal dissent’s modified test would still have us look
    generally (and impermissibly) to the “coherence” of the area and its inhabitants
    and their social and political affinities. See Principal Dissent at 26-30.

    obviously transplanted from another legal source, whether the common law or
    other legislation, it brings the old soil with it.” Felix Frankfurter, Some
    Reflections on the Reading of Statutes, 
    47 Colum. L. Rev. 527
    , 537 (1947).
    An examination of these precedents, the soil in which § 1151(b) was
    germinated, confirms the implausibility of a community of reference test.
    Sandoval dealt with Congress’s constitutional authority to include pueblos within
    “Indian country.” The defendant in that case was prosecuted for bringing alcohol
    into the Santa Clara Pueblo. He was charged under a federal statute that “ma[de]
    it a punishable offense to introduce intoxicating liquor into the Indian country,”
    and another statute specifically providing that all of the Santa Clara Pueblo
    constituted “Indian country.” Sandoval, 
    231 U.S. at 36-37
    . Faced with these
    statutes, the Supreme Court was asked to decide whether Congress had the power
    to deem the pueblos part of Indian country. The Court answered in the
    affirmative, reasoning that the Indian Commerce Clause of the Constitution and
    “an unbroken current of judicial decisions have attributed to the United States . . .
    the power and the duty of exercising a fostering care and protection over all
    dependent Indian communities within its borders.” 
    Id. at 46
     (emphasis added).
    W hile not a formal Indian reservation or allotment that might fall into today’s
    § 1151(a) and (c) categories, the Court noted that Congress had “recognized the
    Pueblos’ titles to their ancestral lands by statute,” executive orders had “reserved
    -53-
    additional lands ‘for the [Pueblos’] use and occupancy,’” and “Congress had
    enacted legislation . . . ‘in the exercise of the Government’s guardianship over
    th[e] [Indian] tribes and their affairs’ . . . including federal restrictions on the
    land’s alienation.” Venetie, 522 U.S. at 528 (quoting Sandoval, 
    231 U.S. at 39, 48
    ) (emphasis added). In this way, the Court held, Congress had taken deliberate
    and independent actions to set aside the land in question and guarantee its federal
    superintendence, thereby rendering it a federally dependent Indian community.
    M cGowan is to the same effect. The case arose when the United States
    sought the forfeiture of two automobiles used to introduce alcohol into the Reno
    Indian Colony, which consisted of a single tract of land bought and owned by the
    federal government as a “permanent settlement” for “needy Indians scattered over
    the State of Nevada.” M cGowan, 
    302 U.S. at 537
    . The question presented to the
    Court was whether the Colony constituted “Indian country” under the same
    criminal statute at issue in Sandoval. The Court concluded that the Colony, while
    neither a reservation nor an allotment, constituted a “dependent Indian
    communit[y],” 
    id. at 538
    , because all of its land had been “validly set apart for
    the use of the Indians” and remained “under the superintendence of the
    government,” 
    id. at 539
    . As Venetie explained, the M cGowan Court stressed that
    “like Indian reservations generally, the colony had been ‘validly set apart’”
    because the “Federal Government had created the colony by purchasing the land
    -54-
    with ‘funds appropriated by Congress,’” and it was federally superintended
    because “the Federal Government held the colony’s land in trust for the benefit of
    the Indians residing there.” Venetie, 
    522 U.S. at 529
     (quoting M cGowan, 
    302 U.S. at 537, 539
    ). 1 8
    Nothing in Sandoval or M cGowan suggests that the metes and bounds of
    “dependent Indian communities” should be determined by a court’s perceptions
    about local social, political, or geographic affinities. Rather, in both cases, the
    Supreme Court identified “dependent Indian communities” based on congressional
    intent, as expressed in independent statutory declarations. Both decisions
    emphasized that “the questions whether, to what extent, and for what time
    [Indians] shall be recognized and dealt with as dependent tribes requiring the
    guardianship and protection of the United States are to be determined by
    Congress, and not by the courts.” Sandoval, 
    231 U.S. at 46
     (emphasis added); see
    also M cGowan, 
    302 U.S. at
    538 & n.9 (citing Sandoval, 
    231 U.S. at 46
    ). And
    18
    The fact that Sandoval and M cGowan rested on an outdated sense of
    cultural superiority, viewing the Indian communities at issue as dependent and in
    need of paternalistic guidance by the federal government, may be further reason
    to tread carefully before haphazardly expanding the subsection (b) class of
    “dependent Indian community” lands without express congressional direction.
    See, e.g., James E. Lobsenz, “Dependent Indian Communities”: A Search for a
    Twentieth Century Definition, 
    24 Ariz. L. Rev. 1
    , 2 (1982) (“The
    ‘quasi-sovereign’ or ‘dependent’ status of the Indian tribe is inextricably linked to
    past concepts of the Indian as an uncivilized savage who was to be gradually
    elevated to the level of a civilized human being.”).
    -55-
    both explained Congress must express its intent to make land a “dependent Indian
    community” by explicitly setting aside the land for Indian use and authorizing the
    federal government to superintend the land for that purpose. Cf. Felix S. Cohen’s
    Handbook of Federal Indian Law, Ch. 1, § 3 at 7 (Robert L. Bennett & Frederick
    M . Hart eds., 1971) (reprinting original 1942 edition) (hereinafter “Cohen
    (1942)”) (summarizing Sandoval as explaining “that the term Indian country as
    applied to the Pueblos means any lands occupied by ‘distinctly Indian
    communities’ recognized and treated by the Government as ‘dependent
    communities’ entitled to its protection”).
    Venetie, thus, is nothing new under the sun. It simply reaffirms what the
    Supreme Court has always held to be the case: the dependent Indian community
    inquiry centers on whether Congress (or the Executive, by delegation) has taken
    some explicit action to set aside the land in question for Indian use and whether
    the land remains federally superintended. As always, we do well to follow the
    Supreme Court’s guidance — most especially when that guidance has received the
    blessing of Congress through codification. Yet, EPA (like the dissents) makes no
    attempt to grapple with any of § 1151(b)’s considerable history and would instead
    have us view it in a vacuum, extirpated from the soil in which it grew.
    Though not dispositive to our analysis, it also merits noting that the historic
    meaning of the statute recently received further congressional confirmation.
    -56-
    Seeking to salve a dispute over the status of privately held lands within New
    M exico pueblos, Congress passed the Indian Pueblo Land Act Amendments of
    2005, Pub. L. No. 109-133, 
    119 Stat. 2573
    , codified at 
    25 U.S.C. § 331
     Note.
    The law provides for federal and tribal criminal jurisdiction over offenses
    committed involving Indians “anywhere within the exterior boundaries of any
    grant from a prior sovereign, as confirmed by Congress or the Court of Private
    Land Claims[, an Article I court established by Congress,] to a Pueblo Indian
    tribe of New M exico.” 
    Id.
     If the community of reference test is correct, this law
    is surplusage, a waste of everyone’s time and effort in writing, passing, and
    signing. Under the community of reference test, if and when a pueblo qualifies as
    an “appropriate community” (and surely that would be most of the time),
    everything in it, including privately held lands, is automatically subject to federal
    or tribal jurisdiction under § 1151(b). No additional law was or is or will ever be
    needed. The fact that Congress thought otherwise is one more (not
    inconsiderable) piece of evidence against the community of reference test — as is
    Congress’s continued focus on boundaries “confirmed by Congress” or its
    designee, rather than on boundaries set by litigation over the latest social
    statistics.
    C
    -57-
    The structure of § 1151 further confirms our understanding. The notion
    that some explicit, congressionally approved action is required to create “Indian
    country” is hardly foreign to the statute’s design. Subsection (a) classifies
    reservations as Indian country, and reservations are traditionally created by and
    delineated according to boundaries Congress has set or sanctioned.
    Subsection (c) recognizes allotments as Indian country, and allotments, too, are a
    product of congressional action, either directly or through delegation. Subsection
    (b) serves as something of a catch-all provision, encompassing “a limited category
    of Indian lands that are neither reservations nor allotments” but that are still
    explicitly set aside for Indians by congressional mandate and superintended by the
    federal government. Venetie, 
    522 U.S. at 527
    . In all three of § 1151’s
    subsections, then, the creation of Indian country hinges on some explicit action by
    Congress (or the Executive, acting under delegated authority). W ithout some
    textual indication to think otherwise, it would be anomalous to think that
    subsection (b) alone was designed to permit the judiciary to commission or
    decommission Indian country by means of an atextual, multi-factor balancing test.
    EPA attempts to overcome this by arguing that § 1151 as a whole is imbued
    with an “anti-checkerboard” purpose. The Agency worries that looking to the
    congressionally approved status of each parcel of land will result in a patchwork,
    with some lands falling under federal jurisdiction while neighboring ones are
    -58-
    subject to state jurisdiction. In support of this argument, EPA cites Seymour v.
    Superintendent of Washington State Penitentiary, 
    368 U.S. 351
    , 358 (1962), and
    the 2005 edition of Cohen’s Handbook of Federal Indian Law. See also Principal
    Dissent at 10-11; Separate Dissent at 4. But this argument overstates the statutory
    case against checkerboarding. In Seymour, the Court simply observed the
    obvious: subsection (a), by its express terms, includes within the definition of
    Indian country all lands within the congressionally prescribed boundaries of a
    reservation, including private fee lands. The 2005 edition of Cohen’s Handbook
    adds nothing new to the mix, citing only Seymour. M eanwhile, the 1982 edition
    of the Handbook on which the principal dissent relies expressly acknowledges
    that § 1151 “does not eliminate all forms of ‘checkerboarding.’” See Felix S.
    Cohen’s Handbook of Federal Indian Law, Ch. 1, § D3c, at 39 & n.105 (Rennard
    Strickland et al. eds. 1982) (hereinafter “Cohen (1982)”).
    By indicating in subsection (a) that all lands within reservations are Indian
    country, Congress undoubtedly did something to mitigate the potential for
    checkerboard jurisdiction, as EPA observes. But Congress did not pursue this
    goal single-mindedly throughout § 1151 at the expense of all other purposes.
    Indeed, as this court has previously explained, “Congress has authorized
    checkerboard jurisdiction under its definition of Indian country in 
    18 U.S.C. § 1151
    . Although subsection 1151(a) clarifies that checkerboard titles within an
    -59-
    existing reservation do not affect the status of an Indian reservation as
    reservation, subsections 1151(b) and (c) allow checkerboard jurisdiction outside
    reservation boundaries.” Yazzie, 
    909 F.2d at 1421-22
     (emphasis omitted). In this
    respect, then, § 1151 is just one more example of the fact that “[n]o legislation
    pursues its purposes at all costs” without consideration of competing goals and
    concerns. Pension Benefit Guar. Corp. v. LTV Corp., 
    496 U.S. 633
    , 646 (1990)
    (quoting Rodriguez v. United States, 
    480 U.S. 522
    , 525-26 (1987) (per curiam));
    see also John F. M anning, Textualism and the Equity of the Statute, 
    101 Colum. L. Rev. 1
    , 18 (2001) (“Because statutory details may reflect only what competing
    groups could agree upon, legislation cannot be expected to pursue its purposes to
    their logical ends; accordingly, departing from a precise statutory text may do no
    more than disturb a carefully wrought legislative compromise.”). 1 9
    19
    The dissents say we should “listen” to the Cohen Handbook’s purported
    condemnation of checkerboarding. Separate Dissent at 4; see also Principal
    Dissent at 9-10, 20-21. Of course, we have and do listen to anyone who offers
    some valuable insight. But the various versions of the Handbook have hardly
    been as clear on this point as the dissents suggest. The 1982 edition
    acknowledged, as we did in Yazzie, that § 1151 “does not eliminate all forms of
    ‘checkerboarding.’” Cohen (1982) Ch. 1, § D3c, at 39 n.105. The original
    edition of the Handbook — the only one authored by Professor Cohen’s hand —
    was precise in reading Sandoval and M cGowan, the progenitors of the term
    “dependent Indian communities,” as including within Indian country only lands
    “which have been validly set apart for the use and occupancy of Indians.” Cohen
    (1942) Ch. 1, § 3, at 8. And the language from the 2005 edition on which the
    dissents rely appears in a single sentence, citing and discussing only a § 1151(a)
    case. Surely, a stray sentence in one edition of a treatise — a sentence that cites

    -60-
    In truth, Congress has authorized some degree of checkerboard jurisdiction
    in all three § 1151 categories of Indian country. As EPA stresses, subsection (a)
    evinces the strongest effort to minimize checkerboarding by declaring all lands
    within Indian reservations, including private fee lands, to be Indian country. But
    even this rule has its exceptions. So, for example, in the Indian liquor laws,
    Congress has excluded from Indian country any private “fee-patented lands in
    non-Indian communities,” even if they are located within reservations. 
    18 U.S.C. §§ 1154
    (c), 1156; see also United States v. M azurie, 
    419 U.S. 544
     (1975). 2 0
    19
    (...continued)
    no § 1151(b) case for support, that was authored many decades after the passage
    of the statute, and that is seemingly at odds with previous editions — cannot be
    the alpha and omega of this court’s inquiry into statutory meaning.
    20
    The dissents read M azurie to suggest that the Supreme Court has
    adopted an approach similar to the community of reference test for evaluating
    cases under 
    18 U.S.C. § 1154
    (c)’s “non-Indian communities” exception. See
    Principal Dissent at 13-14; Separate Dissent at 2-3. But M azurie deals with an
    entirely different statutory provision removing from “Indian country” certain
    lands within the boundaries of a reservation — land that Congress has otherwise
    directed should be treated as “Indian country” under § 1151(a). Although the
    terms “non-Indian communities” and “dependent Indian communities” both
    concern communities, they deal with markedly different types of communities.
    And so the analysis to determine the bounds for each unsurprisingly differs. As
    Venetie explains, § 1151(b) requires a showing that Congress has designated the
    land as an Indian community (set-aside) and that the community is federally
    dependent (federal superintendence), while § 1154(c) non-Indian communities
    plainly require neither of these characteristics. Thus, although M azurie tells us
    something about how to identify non-Indian communities under § 1154(c), it tells
    us nothing about how to identify dependent Indian communities under § 1151(b).
    The Supreme Court itself noted just this point. See M azurie, 
    419 U.S. at
    553 n.10
    (“W e note that the § 1154(c) exception is available for fee-patented lands which
    (continued...)
    -61-
    Checkerboarding is also an unavoidable byproduct of subsection (c), as
    Yazzie and Cohen’s Handbook note. See Yazzie, 
    909 F.2d at 1421-22
    ; Cohen
    (1982) Ch. 1, § D3c, at 39 n.105 (“[A]n irregular arrangement of Indian country
    can exist through the inclusion of off-reservation allotments in its definition.”).
    By definition, allotments outside reservations are stray plots, pieces of land,
    parcels. Set aside and superintended for Indians, they are Indian country even
    while neighboring territory is not. The “checkerboard region” of New M exico
    bears witness to all this, with Indian allotments lying cheek by jowl with lands
    owned by private persons or the state or the federal government. See Appendix.
    To be sure, Congress sought to mitigate, to a degree, the checkerboarding created
    by the allotment system by extending federal jurisdiction over “all Indian
    allotments, the Indian titles to which have not been extinguished, including
    rights-of-way running through the same.” 
    18 U.S.C. § 1151
    (c) (emphasis added).
    But this hardly eliminates the checkerboard jurisdiction that allotments inevitably
    create. Indeed, nothing we might do today will ameliorate the checkerboard
    nature of the area in which HRI’s land lies. The allotment system of subsection
    20
    (...continued)
    are in non-Indian communities, rather than for those which are not in Indian
    communities. This fact renders irrelevant the inability of prosecution witnesses to
    specify precise boundaries of the Fort W ashakie Indian community.”).
    -62-
    (c) bears the lion’s share of blame for the area’s jurisdictional patchwork, and no
    interpretation of subsection (b) will change that unavoidable fact.
    W hile no interpretation of § 1151(b) can eliminate the area’s
    checkerboarded character, Venetie’s set-aside and superintendence requirements
    at least ensure that the boundaries of dependent Indian communities will be
    precisely and predictably defined. Under the community of reference approach
    favored by EPA, these boundaries would be defined in a more convoluted and less
    predictable manner. And even after a “community of reference” is defined, its
    boundaries would likely be irregular, jigsawed, and themselves often hard to
    discern, as the boundaries of many communities are.
    One glance at a map of the Church Rock Chapter confirms as much. See
    Appendix. The Chapter includes within its boundaries a narrow jog across
    Interstate 40 and a small chunk of land south of the highway. And there it
    includes a long strip of private fee lands along the Chapter’s southeastern
    boundary, yet (without explanation) not other immediately adjacent private fee
    lands. At the same time, in the center of the Chapter lies Red Rock State Park,
    which the Chapter excludes from its boundaries, creating a sort of doughnut hole
    (and raising the perplexing question: to what — noncontiguous — “community of
    reference” might the park belong?). If that weren’t enough, and seemingly at
    odds with the exclusion of this particular piece of state-owned property, the
    -63-
    Chapter purports (again without explanation) to include other state-owned lands
    within its boundaries. Far from curing a checkerboard problem, the upshot of the
    community of reference test is to invite an odd sort of parquetry all its own. 2 1
    W orse still, the community of reference test creates multiple, unpredictable,
    and shifting checkerboards — and does so in the context of a criminal statute, in
    tension with the “basic principle” of due process “that a criminal statute must
    give fair warning of the conduct that it makes a crime.” Bouie v. City of
    Columbia, 
    378 U.S. 347
    , 350 (1964); cf. Flores-Figueroa v. United States, 
    129 S. Ct. 1886
    , 1895 (2009) (Scalia, J., concurring in part and concurring in the
    judgment) (calling expansions of criminal liability based on factors outside the
    statute’s text “not unlike the practice of Caligula, who reportedly wrote his laws
    in a very small character, and hung them up upon high pillars, the more
    effectually to ensnare the people” (internal quotation marks omitted)).
    The Supreme Court has repeatedly warned us against the “judicial
    expansion of narrow and precise statutory language” in the criminal context
    21
    EPA and the principal dissent fail to explain how the Red Rock
    doughnut hole might permissibly be excluded from their community of reference,
    while “a vacant lot in the middle of a developed neighborhood” must be part of
    the surrounding community. Principal Dissent at 9-10. It seems the only possible
    explanation they might offer is that the Navajo Nation has chosen to exclude the
    Red Rock State Park from the Church Rock Chapter boundaries. And this
    highlights one way the community of reference can go wrong, by impermissibly
    delegating to a tribe Congress’s authority to define “Indian country.” See
    Venetie, 
    522 U.S. at
    531 n.6.
    -64-
    because “a deprivation of the right of fair warning can result not only from vague
    statutory language but also from an unforeseeable and retroactive judicial
    expansion” of statutes. Bouie, 
    378 U.S. at 352
    .2 2 This is a principle we cannot
    help but bear in mind even here, in a civil case. It remains, after all, a criminal
    statute we are expounding. And this is no mere “technical[ity]” or “hypothetical.”
    Principal Dissent at 7; Separate Dissent at 4. Though EPA has chosen, for now at
    least, to link its SDW A permitting authority to the scope of a criminal statute, it
    may not have to live with this regulatory decision forever. Our interpretation of
    the statute, meanwhile, will apply to all criminal cases arising under § 1151(b)
    and cannot so easily be discarded. 2 3

    right court to decide those claims.”

     As a result, such tests “produce appeals

    -65-
    Venetie supplies a test that is consistent with the statute’s meaning, history,
    and structure; and asking whether a piece of land has been explicitly set aside for
    Indian use and is federally superintended is a reasonably precise and clear task.
    The community of reference test, by contrast, is anything but these things.
    Consider the couple who pops a bottle of champagne to celebrate their vacation
    on private land in New M exico that is neither set aside nor superintended for
    Indians. Say it turns out that the land beneath their picnic blanket is within the
    political boundaries a Navajo Chapter has asserted for itself. Has the couple just
    committed a federal offense by introducing alcohol into a dependent Indian
    community? See 
    18 U.S.C. §§ 1154
    , 1156. Under EPA’s approach, no one could
    be sure until a court has conducted a multi-factor community of reference test and
    tallied up the set-aside and superintendence percentages. Under that test, the
    legality of one’s actions would thus become a post hoc guessing game. W hich
    nearby community might the court pick as its community of reference? Is the
    community’s population cohesive enough? Are there enough businesses in town
    to make it a true “mini-society”? W hat percentage of the land within the
    community’s boundaries is federally set aside and superintended? Is that
    23
    (...continued)
    results and settlements will reflect a claim’s legal and factual merits.” 
    Id.
    -66-
    percentage enough to make it a dependent Indian community? One wrong guess,
    and the pop of a champagne cork makes our couple federal offenders.
    The case before us illustrates just how hard all that guessing can be. EPA
    determined that the appropriate community of reference in this case was the
    Church Rock Chapter, despite evidence that most of the Chapter’s residents work
    in Gallup; most services and infrastructure are provided by the city, county, or
    state; the entire area around Section 8 is uninhabited and, in the Chapter’s words,
    “not suitable for community . . . development”; and EPA itself has concluded that
    no community is ever likely to use the aquifer under HRI’s land as a source of
    drinking water. On a record like this, it seems one might just as easily have
    determined that the “appropriate” community of reference was larger than the
    Chapter, perhaps embracing Gallup or all of M cKinley County. Or, perhaps just
    as plausible, an area smaller than the Chapter, comprising only those outlying
    “rugged mountain ranges, canyons, and highlands” that the Chapter has indicated
    aren’t suitable for development. See HRI II, 
    562 F.3d at 1269
     (Frizzell, J.,
    dissenting). Or perhaps one might have even concluded that HRI’s land just isn’t
    part of any community at all. The whole exercise takes on the feel of Goldilocks,
    searching for an “appropriate” community of reference that feels “just right.”
    And that’s just the start of things. Having defined a community of
    reference, it still remains under the approach urged by EPA and the dissents to
    -67-
    ask whether a sufficient degree or percentage of the land in that community is set
    aside and federally superintended. But the requisite degree or percentage, of
    course, is specified nowhere in the text of the statute, our pre-Venetie precedent,
    EPA’s land status determination, or the dissenting opinions. It must be, then, that
    this is a sort of I-know-it-when-I-see-it test. Cf. Jacobellis v. Ohio, 
    378 U.S. 184
    ,
    197 (1964) (Stewart, J. concurring). EPA and the principal dissent tell us that
    78% set-aside and 92% federal superintendence is sufficient. Land Status
    Determination at 11-12; Principal Dissent at 32-33. But one can’t help to
    wonder: W ould 70% set-aside and 90% superintendence cut it? And what
    happens when those percentages fall a bit farther still? Or if the numbers are
    reversed? Such extra-statutory guesswork is hardly the stuff on which criminal
    determinations should turn. 2 4
    Neither would the scope of “appropriate communities of reference” remain
    stable under EPA’s approach. W ith such nebulous criteria to employ, different
    courts would surely reach different conclusions about whether the same parcel of
    land falls within one community of reference or another — and thus reach
    competing holdings about which sovereign enjoys primary criminal law authority.
    24
    EPA can’t even be sure of the percentages on which it relies. As the
    principal dissent acknowledges, the Agency’s figures “do not add up exactly to
    100% .” Principal Dissent at 2 n.1. W e are told not to worry, though, because the
    various percentages in the record are “within 2.4 % ” of each other, 
    id.,
     and this
    margin of error is — we are left to presume — no big deal.
    -68-
    W orse still, and as we have already noted, even the same court may take a
    different view about a community of reference’s boundaries at different times —
    shrinking or expanding those boundaries depending on social or political changes
    in the area. See supra Section III.A. So just because a piece of land was (or
    wasn’t) Indian country at the time of the last judicial decision, that’s no guarantee
    the result would be the same next time. No one could be sure.
    The dissents’ approach would complicate things further still by introducing
    the possibility of special purpose communities of reference. Given the
    “environmental context” in which this case arises, the principal dissent would
    have us consider presumed “common hydrolog[ical]” links between HRI’s land
    and other parts of the Chapter. Principal Dissent at 14-15, 27. But one would
    think that, in non-environmental cases, courts would not be obliged to look at the
    hydrological “context” when trying to determine the appropriate community of
    reference. W ho, after all, would fault the parties and court for failing to consider
    hydrological details in, say, a more conventional § 1151(b) case involving a
    conspiracy to commit various burglaries? Presumably, under the dissents’
    approach, a court would instead focus on whatever the relevant “context” of the
    case at hand may be. So, to take the burglary case, a court would presumably take
    account of the “burglary context” in which the case arises. If strong links are
    found to exist between the housing markets in Church Rock and Gallup, the court
    -69-
    might then conclude that the “appropriate” community of reference in that
    “context” encompasses both. The appropriate community of reference in an
    environmental case thus could be different than the appropriate community of
    reference in a burglary case, and both might be different than the right community
    of reference in still other kinds of cases. So it is that the same piece of land could
    be both Indian country and not Indian country even in the same court at the same
    time — depending, that is, on the “context” of the case. 2 5
    In this way, the community of reference test invites not just a checkerboard,
    but a virtually three-dimensional checkerboard, a sort of ever-shifting
    jurisdictional Rubik’s cube, “jettisoning relative predictability for the open-ended
    rough-and-tumble of factors” that assures “complex argument[s] in [the] trial
    court and . . . virtually inevitable appeal[s].” Jerome B. Grubart, Inc. v. Great
    Lakes Dredge & Dock Co., 
    513 U.S. 527
    , 547 (1995). And precisely because of
    25
    The dissents’ approach rests on the factual premise that Section 8 shares
    a common “hydrology [with] the entire Church Rock Chapter,” such that “any
    pollution into the aquifers” under Section 8 “would likely affect much of the
    Chapter population.” Principal Dissent at 27-28. EPA, however, disputes this
    premise, having concluded that any aquifer affected by HRI’s operations on
    Section 8 “cannot now and will not in the future serve as a source of drinking
    water.” See supra Section I.C. And the dissents cite no record authority to
    support their competing claim. W hile this court is no less sensitive than the
    dissents to the potential contamination of drinking water, we can claim no
    expertise on the hydrology of M cKinley County and have no idea whether EPA’s
    scientific assessment (unchallenged by the parties before us), or the dissents’, is
    correct. W e can be certain, however, that the plain language of § 1151(b) doesn’t
    require us to become hydrological experts to apply the law.
    -70-
    the test’s complexity, this dispute has dragged on, year after year, decade after
    decade, through regulatory proceedings, an appeal, a remand, and an appeal yet
    again. Since NM ED granted HRI a UIC permit in 1989, the lawyers have fought,
    the parties have lobbied, and an agency and the courts have stewed over the
    mushy ingredients in the community of reference soup, all in an effort to get the
    recipe “just right.” So it is that this dispute has nearly reached the age of
    majority waiting to be served the perfected answer.
    Despite all this, the principal dissent levels the remarkable accusation that
    our decision today “introduc[es] confusion” into an area of law “settled for
    decades” and “overturn[s] decades of our precedent.” Principal Dissent at 2; see
    also id. at 31. But not only is the atextual community of reference test the source
    of confusion in this area of law, it is hardly as old or as venerated as the dissents
    would have it. In fact, the community of reference test is younger than this
    dispute; it’s been around for only fifteen of the sixty-two years since Congress
    -71-
    enacted § 1151(b).2 6 And in that time, the test has always been a work in
    progress, anything but “settled.”
    In the first place, the test has been applied only a few times since its
    genesis, and sporadically at that. After Watchman created the test in 1995, we
    applied it in a published opinion only once before Venetie came along in 1998.
    See Adair, 
    111 F.3d at 774-75
    .2 7 W hen the Supreme Court speaks, it (of course)
    supercedes our prior case law. And in 1999, in the first § 1151(b) case following
    Venetie, we did not use the community of reference test, but straightforwardly
    applied Venetie’s two requirements. See Roberts, 
    185 F.3d at 1133
    . In a second
    post-Venetie case that followed several years later, we appeared to split the
    difference, saying “[w]e examine the entire Indian community,” but conducting no
    community of reference analysis and holding only that “lands within the exterior
    boundaries of a Pueblo land grant, to which the Pueblo hold title, are Indian
    26
    The principal dissent pegs the test’s age at twenty, citing the Yazzie
    decision from 1990. But that’s mistaken. Yazzie adopted a holding under
    § 1151(a), not § 1151(b), and thus said nothing about a community of reference
    test. The principal dissent’s citation to Yazzie points to that decision’s appendix,
    where this court merely reproduced (without endorsement) the district court
    opinion discussing § 1151(b) in a consolidated case. That’s why, five years later
    in Watchman, this court called the community of reference question “a question of
    first impression.” 
    52 F.3d at 1543
    .
    27
    In an unpublished decision also preceding Venetie, a panel of this court
    acknowledged the existence of the community of reference test but declined to
    apply it because it “was not addressed by the parties or the district court.” Eaves
    v. Champion, 1997 W L 291186, at *2 n.4 (10th Cir. 1997) (unpublished).

    country.” United States v. Arrieta, 
    436 F.3d 1246
    , 1250-51 (10th Cir. 2006)
    (emphasis added). Thus, the only Tenth Circuit case clearly to employ the
    community of reference test after Venetie is this case, which created an intra-
    circuit split with Roberts, a fact that led us to grant en banc review.
    In the second place, in each of the (few) cases we’ve applied the test, we’ve
    changed it. Literally. W hen creating the test in Watchman, we identified “two
    organizing principles” — “the status of the area in question as a community” and
    “the context of the surrounding area.” 
    52 F.3d at 1543-44
    . Two years later, in
    Adair, we added another factor concerned with “the geographical definition of the
    area proposed as a community.” 
    111 F.3d at 774
    . And in this case the principal
    dissent would have us reconfigure the factors in its balancing test yet again. See
    supra note 17. In its view, the test should now ask “whether the land . . .
    possesses a reasonable degree of coherence” and “whether the uses to which the
    land is put and the people inhabiting the land possess a reasonable degree of
    coherence.” Principal Dissent at 26.
    Truth be told, then, the confusion in this area of law has been sown by the
    community of reference test. Its lack of any basis in the statute’s text, history, or
    structure, its multifarious and incommensurable competing factors, the
    unpredictable results it yields, and its constant judicial reworking — all of this
    has left the law and litigants confused. Rather than adding to the confusion, our
    -73-
    decision today eschews yet more tinkering in favor of the simple and predictable
    test the Supreme Court has told us to use. 2 8
    D
    Though it does not control our outcome, it’s worth noting that our decision
    today brings the law of this circuit into harmony with the law developed in our
    sister circuits after Venetie. In Blunk v. Arizona Department of Transportation,
    
    177 F.3d 879
     (9th Cir. 1999), the Ninth Circuit acknowledged that “Venetie
    control[led] [its] decision,” and then concluded that the Navajo fee land in
    question before it was not Indian country under § 1151(b) because the land was
    28
    The separate dissent’s suggestion that our decision disregards the
    “effects of a mining operation that may greatly impact the surrounding lands,” is
    likewise unwarranted. Separate Dissent at 5. No one questions that mining
    operations can pose “grave consequences.” Id. It is this court’s hope, no less
    than the hope of the dissents, that the appropriate agencies will do their assigned
    jobs in protecting the environment. See, e.g., M orris v. U.S. Nuclear Regulatory
    Comm’n, 
    598 F.3d 677
     (10th Cir. 2010) (upholding Nuclear Regulatory
    Commission licensing of HRI’s uranium mining plans on Section 8). But we are
    judges, not environmental regulators. As such, “[o]ur charge,” and all this court
    has sought or may properly seek to do, “is to give effect to the law Congress
    enacted.” Lewis v. City of Chicago, 560 U.S. __, Slip Op. at 11 (2010).
    The separate dissent is likewise mistaken when it suggests that today’s
    decision means that HRI’s activities will no longer be “subject to federal
    environmental regulations.” Separate Dissent at 1, 6. As we have explained, the
    SDW A, a federal statute, provides the regulatory framework for all UIC permits
    nationwide. EPA regulations govern when those permits may be issued. Thus,
    although EPA may have delegated to NM ED authority to issue permits in New
    M exico, NM ED may issue its permits only in compliance with federal law
    (SDW A) and federal (EPA) regulations. Indeed, EPA suggested that no case or
    controversy exists before us precisely because of this. See supra Section II.A.
    -74-
    neither set aside nor superintended by the federal government. Id. at 883-84. In
    reaching its conclusion, the Ninth Circuit rejected the notion, lying at the heart of
    EPA’s position here, that the land in question might be considered Indian country
    “because of its proximity or importance to the Navajo Reservation.” Id. at 884.
    The court conducted no community of reference analysis and considered no
    factors other than Venetie’s two requirements. Id. at 883-84.
    In Yankton Sioux Tribe v. Podhradsky, 
    577 F.3d 951
     (8th Cir. 2009), the
    Eighth Circuit conducted a similarly straightforward application of Venetie.
    Considering whether scattered trust lands qualified as Indian country under
    § 1151(b), the Eighth Circuit concluded that all of these lands “easily meet
    [Venetie’s] definition.” Id. at 971. At no point did the court seek to place these
    various parcels within a larger community of reference, nor did it analyze the
    particular parcels at issue in light of any factors other than the two Venetie
    prescribes. See id. Had the Eighth Circuit applied the community of reference
    test urged by EPA, the result in Yankton might have been quite different —
    perhaps the non-Indian lands interspersed among the scattered trust lands might
    have become “Indian country,” or perhaps, if the non-Indian land had
    -75-
    predominated the community, the scattered trust lands might have ceased to be
    “Indian country” under § 1151(b). 2 9
    A state court within our jurisdiction has also rejected this circuit’s
    community of reference jurisprudence in favor of Venetie’s two-part analysis. In
    State v. Frank, 
    52 P.3d 404
     (N.M . 2002), the Supreme Court of New M exico held
    that the § 1151(b) inquiry must focus solely on the land in question, not on some
    broader community of reference. Id. at 409 (“In light of the clear guidelines in
    the Venetie opinion, we decline to incorporate a community of reference inquiry
    into our case law.”). Indeed, the court acknowledged, as we have today, that “the
    six-factor test that was rejected by the Supreme Court in Venetie used essentially
    the same factors as those in” this court’s community of reference test. Id.; see
    also id. (“The Venetie two-prong test redirects our attention . . . away from the
    29
    For this reason, EPA and the principal dissent are wrong when they
    suggest that Blunk and Yankton shouldn’t be read to reject the use of a threshold
    community of reference test because they didn’t consider it. See Principal Dissent
    at 21-24. The fact is that each court put every parcel of land at issue through the
    Venetie two-part test and required that each, not some “percentage” or “degree,”
    satisfy those requirements. In Blunk, none of the Navajo fee land met Venetie’s
    requirements, while in Yankton, all of the miscellaneous trust lands met the two
    requirements. If the community of reference test were an essential threshold
    inquiry, as EPA and the principal dissent argue, it’s unclear how these courts
    could have conducted a proper § 1151(b) analysis without it.

    more nebulous issue of community cohesiveness.” (internal quotation marks
    omitted)). 3 0
    IV
    Ultimately, Venetie compels us to abandon the community of reference test.
    Under the proper test we adopt today, only two questions are relevant in assessing
    30
    The New M exico Supreme Court took a somewhat different approach
    when dealing with private land within pueblo boundaries. See State v. Romero,
    
    142 P.3d 887
    , 895 (N.M . 2006). In Romero, the court held that private land
    within the original land grant of the Taos pueblo is Indian country and therefore
    beyond the state’s criminal jurisdiction. The Romero court distinguished its case
    from Frank on the grounds that pueblos have long been recognized as Indian
    country. See 
    id. at 892
    . Although the court appeared to treat the pueblo as a
    dependent Indian community under § 1151(b), much of its analysis focused on
    comparing pueblos to reservations under § 1151(a). See, e.g., id. at 894 (“W e
    determine that a pueblo satisfying § 1151(b) is sufficiently similar to a reservation
    in § 1151(a) to merit identical treatment for the purposes of criminal
    jurisdiction.”). Along these lines, the court declined to conduct a community of
    reference analysis, and instead analyzed the pueblo as it would a reservation. It is
    not entirely clear how to reconcile Frank and Romero, and to the extent that the
    two cases conflict, we agree with Frank. Land not explicitly set aside and
    superintended is not Indian country under § 1151(b). Neither is it clear whether
    or what remaining force Romero bears today, given that Congress has now spoken
    directly to the criminal jurisdictional status of privately titled lands within pueblo
    boundaries in New M exico. See Indian Pueblo Land Act Amendments of 2005,
    Pub. L. No. 109-133, 
    119 Stat. 2573
    , codified at 
    25 U.S.C. § 331
     Note; see also
    supra Section III.B. Romero was obliged to analyze the land in question under
    § 1151 alone rather than in light of Congress’s new statute because the statute
    didn’t apply retroactively to the case. See Romero, 142 P.3d at n.1; see also
    Robert L. Lucero, Jr., State v. Romero: The Legacy of Pueblo Land Grants and
    the Contours of Jurisdiction in Indian Country, 37 N.M . L. Rev. 671, n.6 (2007)
    (explaining the history and structure of the Act’s jurisdictional grant). And
    considering that Romero explicitly declined to overrule Frank, there can be little
    question that Frank remains governing law in New M exico. See Romero, 142
    P.3d at 892.

    claims of jurisdiction under § 1151(b): (1) Has Congress (or the Executive,
    acting pursuant to delegated authority) taken some action explicitly setting aside
    the land in question for Indian use? (2) Is the land in question superintended by
    the federal government? Because the parties agree that the land in question in
    EPA’s final land status determination — HRI’s segment of Section 8 — is neither
    explicitly set aside for Indian use nor federally superintended, it follows that, as a
    matter of law, the land does not qualify as Indian country under § 1151(b). And
    from this it follows that EPA’s final land status determination holding otherwise
    must be vacated as inconsistent with the statute. W hile the outcome may have
    been different under this circuit’s Watchman test, Venetie is now the law and
    neither we nor EPA may ignore it.
    It may be that Venetie complicates to some degree EPA’s efforts to regulate
    activities affecting underground water sources, which of course don’t follow neat
    land survey lines. But that is because the Agency has chosen, in an exercise of its
    considerable discretion under the SDW A, to limit its primary regulatory authority
    over water quality to those Indian lands encompassed by § 1151, a criminal
    jurisdictional statute. W hile § 1151 does its job of assigning prosecutorial
    authority over particular tracts of land tolerably well, it is perhaps unsurprising
    that it may prove less satisfactory when it comes to allocating regulatory authority
    -78-
    over aquifers running beneath those lands. Crimes, after all, usually occur on
    land, not in aquifers.
    Someday, EPA may seek to avoid these difficulties by unhitching its UIC
    permitting authority from § 1151. W e do not purport to pass on the propriety or
    wisdom of such a move. For now, we concern ourselves only with EPA’s current
    choice to confine its authority in New M exico to what § 1151 deems Indian
    country. And on that score, we cannot help but conclude that EPA’s final land
    status determination under review is inconsistent with the statute’s terms as a
    matter of law and cannot stand.
    The panel opinion is vacated, the petition for review is granted, and the
    EPA’s final land determination is vacated.

    E B EL , Circuit Judge, joined by B R ISC O E , Chief Judge, H EN R Y , LU C E R O ,
    and M U R PH Y , Circuit Judges, dissenting.
    In Alaska v. Native Village of Venetie Tribal Government, 
    522 U.S. 520
    (1998), the Supreme Court rejected the Ninth Circuit’s multi-factor test for
    determining whether a given area of land constitutes a dependent Indian
    community. Instead, the Court held that a two-part test should be applied to
    determine whether the “land in question” is a dependent Indian community: first,
    by considering whether the land was “set aside by the Federal Government for the
    use of the Indians as Indian land,” and second, assessing whether the land is
    “under federal superintendence.” 
    Id. at 527
    .
    W hile this test is straight-forward enough, the Supreme Court did not
    address a separate, antecedent question: to what area of land should this two-part
    test be applied? In other words, how do we determine the “land in question”?
    Over the last twenty years in this circuit, we have held that a “community-of-
    reference” test must be employed to determine the appropriate community, before
    determining whether that community is both “dependent” and “Indian.” See, e.g.,
    Hydro Res., Inc. v. EPA (“HRI II”), 
    562 F.3d 1249
    , 1261 (10th Cir. 2009); Hydro
    Res., Inc. v. EPA (“HRI I”), 
    198 F.3d 1224
    , 1248 (10th Cir. 2000); United States
    v. Adair, 
    111 F.3d 770
    , 774 (10th Cir. 1997); Pittsburg & M idway Coal M ining
    Co. v. W atchman, 
    52 F.3d 1531
    , 1543 (10th Cir. 1995), abrogated in part by
    Venetie, 
    522 U.S. 520
    ; Pittsburg & M idway Coal M ining Co. v. Yazzie, 
    909 F.2d 1387
    , 1431 (10th Cir. 1990).
    Today, the majority holds that, even though the Court in Venetie did not so
    much as consider the appropriate way to determine the relevant community— and,
    to the extent it did consider the question, it looked at the broader community
    rather than a narrow tract of land— Venetie nevertheless abrogated our
    community-of-reference test. By overturning decades of our precedent, the
    majority introduces confusion into an area of law that had been largely settled,
    and does so based on a case that did not even consider the issue. I respectfully
    dissent.
    I.      B ackground
    The Church Rock Chapter of the Navajo Nation was formally certified as a
    local governmental unit by the Navajo Nation Council in 1955, although residents
    built a Chapter House for local governance purposes in 1946. The Chapter, which
    is located just east of the town of Gallup, New M exico, consists of over 57,000
    acres. The federal government holds approximately 52% of this land in trust for
    the Navajo nation, and holds an additional 26% in trust in the form of allotments
    to individual Indians. The Bureau of Land M anagement (“BLM ”) owns an
    additional 10% of the land, which is subject to grazing leases granted to Navajos.
    -2-
    In addition, the state of New M exico owns about 4% the remaining land, and
    private interests own approximately 6% . 1
    In 1970, United Nuclear Corporation (“UNC”) purchased 160 acres of land
    in the Church Rock Chapter, in the southeast corner of Section 8, Township 16N,
    Range 16W (“Section 8”), from the United States. HRI II, 
    562 F.3d at 1254
    .
    Hydro Resources, Inc. (“HRI”), a non-Indian mining corporation, later purchased
    the land, as well as UNC’s patents for uranium-mining claims on that land, with
    the intent to operate a mine. 
    Id.
     HRI thus owns this land in fee simple. The
    remaining three-fourths of Section 8 are owned by the United States in fee simple.
    Section 8 is surrounded on two sides by land owned by the United States in fee,
    and on two sides by land owned by the United States and held in trust for the
    Navajo.
    No one lives on the Section 8 land, though the three-fourths of Section 8
    not owned by HRI are subject to grazing permits issued by the United States
    Bureau of Indian Affairs (“BIA”). Located approximately six miles northeast of
    the Chapter House, the infrastructure on HRI’s Section 8 land is primarily
    provided by the State of New M exico and M cKinley County. The state maintains
    1
    These figures do not add up exactly to 100% , and the record reflects some
    confusion as to the precise acreages of land owned by these different entities.
    Nonetheless, the various estimates provided in the record are all relatively close
    to one another, within 2.4% . I have cited the estimates used by EPA in its
    Determination, and neither party challenges the substantive accuracy of these
    numbers.
    -3-
    the only access road to Section 8, State Highway 566, and HRI pays annual
    property taxes on the land to M cKinley County. If HRI ever begins operating a
    mine on the property, the Public Service Company of New M exico will provide it
    electricity, and the New M exico State W ater Engineer has already approved HRI’s
    request for water rights.
    In addition to the land in the Chapter being overwhelmingly owned by or
    for Navajos, the demography of the Chapter also shows an overwhelming Navajo
    presence. According to the 2000 census, approximately 98% of the Chapter’s
    2,802 residents are Navajo, and most of the rest are married to a Navajo. The
    residents primarily speak Navajo. M any residents of the Chapter raise livestock
    on Chapter lands— sometimes supplementing their income by producing
    traditional wares such as jewelry, stone and wood carvings, and by sewing and
    weaving— although some work in the nearby town of Gallup, which is located
    outside the boundaries of the Chapter.
    The Chapter House, approximately three miles east of Gallup, acts as the
    social and political center for the Church Rock Chapter. Eighty-eight percent of
    Church Rock residents go to the Chapter House at least once a month. The
    Chapter House includes a Head Start center, elementary school, churches, and
    other buildings that provide for many of the residents’ educational, spiritual, and
    health needs. The Navajo Nation “provides housing, electricity, drinking water,
    wastewater treatment, sewer services, and utilities,” as well as police protection
    -4-
    to residents of the Chapter, and the Chapter itself provides “scholarships, home
    repair and purchase assistance, and meals for seniors.” (R. doc. 44 at 21.) The
    federal government also provides some services in the Chapter, including road
    maintenance, grazing management and permitting, social and health services, and
    conservation services. W hile the state of New M exico and the county maintain
    the main roads, most schools, and provide fire and EM S services, the
    Superintendent of the Eastern Navajo Agency of the BIA confirmed that the BIA
    considers the Church Rock Chapter to be a “distinct communit[y] of Navajo
    Indians who depend primarily on federal and tribal governmental services and
    protection.” (R. doc. 13b at 132.)
    II.      D iscussion
    As discussed more fully in the majority opinion, HRI now seeks a
    determination that EPA incorrectly decided that HRI’s Section 8 land is part of a
    dependent Indian community and thus subject to EPA’s jurisdiction for Safe
    Drinking W ater Act (“SDW A”) purposes rather than the jurisdiction of the New
    M exico Environmental Department (“NM ED”). HRI argues that EPA improperly
    considered the entire Church Rock Chapter in concluding that Section 8 was
    within a dependent Indian community, and that HRI’s Section 8 land, by itself,
    does not constitute a dependent Indian community for purposes of § 1151(b).
    EPA and the Navajo Nation maintain that EPA correctly determined that HRI’s
    -5-
    Section 8 land is within a dependent Indian community and thus is Indian country
    under § 1151(b). 2

    The question presented by this appeal requires the court to determine the
    meaning of the phrase “dependent Indian communit[y]” as used in 
    18 U.S.C. § 1151

    , 1245 (10th Cir. 2009). Title 18, United States Code, Section 1151

    I agree with the majority that EPA’s Determination is not entitled to deference
    under Chevron, U.S.A., Inc. v. Nat’l Res. Def. Council Inc., 
    467 U.S. 837
     (1984).
    I would, however, afford the Determination deference under Skidmore v. Swift &
    Co., 
    323 U.S. 134
     (1944). Skidmore deference is a lesser form of deference in
    which “the weight to be given the agency’s practice in particular circumstances
    depends upon ‘the thoroughness evident in its consideration, the validity of its
    reasoning, its consistency with earlier and later pronouncements, and all those
    factors which give it power to persuade.’” M cGraw v. Barnhart, 
    450 F.3d 493
    ,
    501 (10th Cir. 2006) (quoting Skidmore, 
    323 U.S. at 140
    ). Based on these
    factors, I would defer to EPA’s Determination to a degree “proportional to its
    ‘power to persuade.’” United States v. M ead Corp., 
    533 U.S. 218
    , 235 (2001)
    (quoting Skidmore, 
    323 U.S. at 140
    ).
    The majority states that it is “inappropriate” to consider whether the EPA’s
    Determination warrants Skidmore deference because EPA has not asked for such
    deference. However, “[a] party’s concession on the standard of review does not
    bind the court, as ‘such a determination remains for the court to make for itself.’”

    provides:
    the term “Indian country,” as used in this chapter, means (a) all land
    within the limits of any Indian reservation under the jurisdiction of
    the United States Government, notwithstanding the issuance of any
    patent, and, including rights-of-way running through the reservation,
    (b) all dependent Indian communities within the borders of the
    United States whether within the original or subsequently acquired
    territory thereof, and whether within or without the limits of a state,
    and (c) all Indian allotments, the Indian titles to which have not been
    extinguished, including rights-of-way running through the same.
    
    18 U.S.C. § 1151
     (emphasis added). W hile technically a criminal statute, § 1151
    applies in civil contexts as well. See Venetie, 
    522 U.S. at
    527 (citing DeCoteau
    v. Dist. County Court for Tenth Judicial Dist., 
    420 U.S. 425
    , 427 n.2 (1975)); see
    also Enlow v. M oore, 
    134 F.3d 993
    , 995 n.2 (10th Cir. 1998) (“
    18 U.S.C. § 1151
     .
    . . defines ‘Indian country’ for civil as well as criminal jurisdiction.”).
    It is a well-settled principle of statutory construction that “we are to give
    meaning to every word of a statute where possible.” Smith v. M idland Brake,
    Inc., 
    180 F.3d 1154
    , 1165 (10th Cir. 1999) (en banc) (citing Ratzlaf v. United
    States, 
    510 U.S. 135
    , 140 (1994)). Therefore, I begin from the uncontroversial
    premise that “dependent Indian communities” in subpart (b) must have some
    meaning that is independent from the meanings of “Indian country” provided in
    subparts (a) and (c) of the statute. Subpart (a) includes as “Indian country” “all
    land within the limits of any Indian reservation under the jurisdiction of the
    United States Government.” 
    18 U.S.C. § 1151
    (a). Subpart (c) applies “Indian
    country” to “Indian allotments,” which refers to “land owned by individual
    -7-
    Indians and either held in trust by the United States or subject to a statutory
    restriction on alienation.” Felix S. Cohen, Handbook of Federal Indian Law
    § 3.04[2][c][iv], at 195 (2005 ed.) (hereinafter “Cohen”); see also United States v.
    Ramsey 
    271 U.S. 467
    , 470 (1926). Thus, a “dependent Indian community” must
    refer to something other than reservation lands and allotted lands. Venetie, 
    522 U.S. at 527
     (concluding that the phrase “dependent Indian communities . . . refers
    to a limited category of Indian lands that are neither reservations nor allotments”);
    see also Okla. Tax Comm’n v. Sac & Fox Nation, 
    508 U.S. 114
    , 123 (1993)
    (“Congress has defined Indian country broadly to include formal and informal
    reservations, dependent Indian communities, and Indian allotments . . . .”).
    The use of the word “community” in the statute implies the existence of
    some setting within which the property in question is to be evaluated. Other areas
    of the law that draw upon the notion of a community show that community means
    context. For example, the obscenity standard developed by the Supreme Court in
    the First Amendment arena requires the trier of fact to apply “contemporary
    community standards,” a contextual inquiry that may produce different outcomes
    depending upon the community in which the test is applied. M iller v. California,
    
    413 U.S. 15
    , 32 (1973) (“It is neither realistic nor constitutionally sound to read
    the First Amendment as requiring that the people of M aine or M ississippi accept
    public depiction of conduct found tolerable in Las Vegas, or New York City.”).
    Similarly, when considering whether a governmental action violates the
    -8-
    Establishment Clause of the First Amendment, courts consider whether a
    reasonable observer, “aware of the history and context of the community and
    forum in which the religious display appears,” would consider the action as
    endorsing religion. M cCreary County, Ky. v. ACLU, 
    545 U.S. 844
    , 866 (2005)
    (quoting Capitol Square Review & Advisory Bd. v. Pinette, 
    515 U.S. 753
    , 780
    (1995) (O’Connor, J., concurring in part and concurring in judgment)). Zoning
    regulations are also intended to “facilitate the orderly development of
    communities by confining particular uses to defined areas,” so city planners must
    look at the context of the area in deciding what sorts of uses to allow in the
    community. 83 Am. Jur. 2d Zoning & Planning § 2 (2009). Throughout the law,
    then, the term “community” is used to place the object of judicial scrutiny in an
    appropriate context.
    The structure of § 1151 further demonstrates that community requires a
    contextual analysis rather than the parcel-by-parcel analysis favored by HRI.
    Subsections (a) and (c) of § 1151 both refer to land: § 1151(a) references “all
    land within the limits of any Indian reservation,” and § 1151(c) applies to “all
    Indian allotments,” which are by definition specific tracts of land. See Cohen
    § 3.04[2][c][iv], at 195. Subsection (b), by contrast, does not refer directly to
    land, but instead uses the broader concept of “community.” The ordinary use of
    the term “community” makes it clear that the term necessitates a broader
    approach. Someone looking at a vacant lot in the middle of a developed
    -9-
    neighborhood would not say that the vacant lot is not part of the community that
    surrounds the lot on all sides. Similarly, a parcel of 160 acres completely
    surrounded by a community of 57,000 acres should not fail to be part of that
    community simply because of the ownership status of that parcel.
    The purpose of § 1151 provides additional guidance for the proper
    interpretation of the term “community” in § 1151(b). “[A] central purpose of the
    1948 codification was to avoid checkerboard jurisdiction.” Cohen §
    3.04[2][c][iii], at 194 n.429 (citing Seymour v. Superintendent of W ash. State
    Penitentiary, 
    368 U.S. 351
    , 358 (1962)). Section 1151 was originally passed as a
    criminal statute, and, in passing the statute, Congress sought to foreclose a
    situation in which “law enforcement officers operating in [a checkerboard] area
    [would] find it necessary to search tract books in order to determine whether
    criminal jurisdiction over each particular offense . . . is in the State or Federal
    Government.” Seymour, 
    368 U.S. at 358
    . W hile the Supreme Court in Seymour
    was referring to § 1151(a), which explicitly provides that Indian country applies
    to reservations “notwithstanding the issuance of any patent, and, including rights-
    of-way running through the reservation,” I think the Court meant what it said
    when it stated that “[s]uch an impractical pattern of checkerboard jurisdiction was
    avoided by the plain language of § 1151.” Id.
    Felix Cohen agreed that it is “the full statute [that] was intended to reduce
    earlier difficulties which had arisen from the ‘checkerboarding’ of land ownership
    -10-
    and rights-of-way. Thus, patented parcels of land and rights-of-way within
    dependent Indian communities should also be within Indian country.” Felix S.
    Cohen, Handbook of Federal Indian Law, Ch. 1 § D3c, at 39 (1982 ed.)
    (hereinafter “Cohen (1982)”) (emphasis added). Accordingly, the purpose of
    Congress’s codification of § 1151— to smooth out much of the checkerboard
    jurisdiction that complicated enforcement of criminal law— shows that a
    “community” approach, rather than an isolated parcel-by-parcel approach, should
    be used to determine whether land is Indian country under § 1151(b).
    The majority’s conclusion that title alone is determinative of whether a
    parcel of land is "Indian country" under § 1151(b) would completely eviscerate
    this congressional purpose. 3 The problem of checkerboard jurisdiction is caused
    by an interspersing of Indian-owned and non-Indian-owned lands in a relatively
    3
    The majority claims that its inquiry is solely into whether the specific parcel of
    land at issue is both set aside for Indian use and federally superintended, and thus
    does not focus on title at all. M aj. op. at 42 n.12. However, it is difficult to
    imagine a situation in which a piece of property owned in fee by a private
    individual, examined in isolation from the community in which the parcel of land
    is located, could meet these two criteria. In fact, HRI conceded at oral argument
    that, under its reading of § 1151(b), the inquiry is solely into who owns the land
    in fee. (Oral Argument Recording at 15:55 to 16:10.) In support of its dubious
    claim that title is not determinative under its § 1151(b) test, the majority cites to a
    note accompanying 
    25 U.S.C. § 331
    , which explicitly extends federal and tribal
    criminal jurisdiction to certain acts committed “anywhere within the external
    boundaries of a pueblo.” But this citation to a note accompanying 
    25 U.S.C. § 331
     is simply irrelevant to determining the proper construction of a phrase in 
    18 U.S.C. § 1151
    (b). However the majority chooses to frame it, a determination that
    land is privately held in fee will necessarily foreclose the possibility that the land
    is part of a dependent Indian community.

    small geographic area. Because the checkerboard problem is caused by title,
    Congress would not have sought to remedy the problem by relying exclusively on
    title to determine whether land is Indian country. Furthermore, if Congress had
    intended title to be determinative, it easily could have said so in § 1151. Instead,
    two of the three subsections of the statute (§ 1151(a) and (c)) clearly indicate that
    title is not determinative, and the third subsection (§ 1151(b)) uses a word,
    "communities," that, as discussed above, is inconsistent with a focus solely on
    title. In fact, the only time Congress alludes to title at all in the statute is to state
    that title is not determinative of land's Indian country status. See 
    18 U.S.C. § 1151
    (a) (defining Indian country to include "all land within the limits of any
    Indian reservation . . . notwithstanding the issuance of any patent, and, including
    rights-of-way running through the reservation"); 
    id.
     § 1151(c) (including rights-
    of-way running through Indian allotments as Indian country). W hile the Supreme
    Court has held that privately-owned land can constitute Indian country under §
    1151, see Solem v. Bartlett, 
    465 U.S. 463
    , 468 (1984) (applying § 1151(a) to
    hold that "Indian country . . . include[s] lands held in fee by non-Indians"), today,
    this court becomes the first federal appellate court to hold that land is not Indian
    country solely because of who owns title. The language of the statute simply does
    not compel such a drastic result.
    This interpretation of the word “communities” in § 1151(b) is consistent
    with the meaning the Supreme Court gave to that word in a related Indian statute.
    -12-
    Section 1154, which prohibits the introduction of spirituous beverages into Indian
    country, starts with the same definition of “Indian country” found in 
    18 U.S.C. § 1151
    , but then specifically restricts that term, for the purposes of § 1154, by
    excluding “fee-patented lands in non-Indian communities or rights-of-way
    through Indian reservations” from Indian country status. 
    18 U.S.C. § 1154
    (c)
    (emphasis added).4 The obvious inference to be drawn from this exclusion is that
    the status of a particular parcel of land as “fee-patented” is not determinative of
    its status as “Indian country” under § 1151, or else there would have been no need
    to specifically exclude such lands from the “Indian country” definition in § 1154.
    In interpreting § 1154, the Supreme Court also confirmed this interpretation
    of the word “communities.” In United States v. M azurie, the defendants were
    charged under 
    18 U.S.C. § 1154
     with introducing spirituous beverages into Indian
    country. 
    419 U.S. 544
    , 545 (1975). 5 The defendants in M azurie operated a bar
    within the boundaries of the W ind River Reservation in central W yoming, but
    “substantial tracts of non-Indian-held land are scattered within the reservation’s
    boundaries,” and the bar itself was located on privately-owned fee land within the
    reservation. 
    Id. at 546-47
    . The Court agreed that the unincorporated town and
    4
    Section 1156, prohibiting the unlawful possession of intoxicating liquors in
    Indian country, also contains this definition of “Indian country.” 
    18 U.S.C. § 1156
    .
    5
    In Venetie, the Supreme Court did not criticize, or even refer to, M azurie, and
    so the approach adopted by the Court in M azurie remains valid.
    -13-
    surrounding areas were an “Indian community” within the meaning of 
    18 U.S.C. § 1154
    (c), based principally on the fact that over 80% of the families in the area
    were Indian, and 223 out of the 243 students enrolled in the nearby school were
    Indian. 
    Id. at 550-52
    . The Court thus gave meaning to the word “communities”
    in the statute by looking at the surrounding area of land in which the bar was
    located, rather than simply looking at the plot of land itself. This further
    demonstrates that the word “communities,” as used in the Indian statutes, requires
    an approach that places the specific parcel of land at issue in the context of the
    surrounding area. 6
    Finally, it should be remembered that this case arises specifically in an
    6
    Sections 1151, 1154, and 1156 were all enacted together in 1948 as part of the
    Indian M ajor Crimes Act, and the “non-Indian communities” language was added
    to sections 1154 and 1156 the following year. Indian M ajor Crimes Act, ch. 645,
    
    62 Stat. 757
    -59 (1948); Act of M ay 24, 1949, ch. 139, 
    63 Stat. 94
    . This statutory
    history supports interpreting these statutes together. See W atchman, 
    52 F.3d at
    1544 n.13 (“The courts have looked to non-Indian community cases and
    dependent Indian community cases when addressing either issue.”).
    As mentioned above, the majority cites to a statute enacted in 2005 that
    unambiguously provides for federal and tribal criminal jurisdiction in certain
    instances within the exterior boundaries of a pueblo as proof that § 1151(b) did
    not already extend jurisdiction to such lands. M aj. op. at 54 (citing 
    25 U.S.C. § 331
     Note). To the extent a statute passed in 2005 has any significance to this
    court’s interpretation of a statute passed in 1948, however, it shows only that
    Congress wanted to unambiguously extend federal and tribal jurisdiction within
    pueblos rather than rely on the contested interpretation of § 1151(b).
    Accordingly, I consider the code provisions passed contemporaneously with §
    1151 and that courts have consistently interpreted as interrelated with § 1151, see
    W atchman 
    52 F.3d at
    1544 n.13, to be more instructive to the meaning of § 1151
    than a bill passed five years ago and codified in a different title of the United
    States Code.
    -14-
    environmental context. This case is before the court as a review of a
    determination made by the EPA pursuant to the SDW A that the portion of Section
    8 at issue is a dependant Indian community and that “EPA is therefore the
    appropriate agency to consider underground injection control permit applications
    under the [SDW A] for that land.” (R. doc. 44 at 1.) In the natural resources
    context, the notion of community assumes heightened importance. Aquifers
    generally are not found underneath just one specific isolated parcel of land, but
    rather extend under surrounding lands as well, and indeed the aquifer underneath
    HRI’s Section 8 land runs underneath much of the Chapter. The externalities
    produced by a mining operation— including pollution, traffic, and the aesthetic
    harms created by having a large mining operation nearby— also affect the
    surrounding community. Indeed, the SDW A recognizes that water is a communal
    good that is affected by those around it and focuses much of its protection on
    “community water system[s].” 42 U.S.C. § 300f(15). Given the potential for
    diffuse harm posed by a mining operation, then, encouraging the checkerboard
    jurisdiction that Congress sought to avoid in enacting § 1151 makes even less
    sense in the SDW A context than it does in the criminal context in which the
    statute was originally enacted.
    For these reasons, the word “communities” in § 1151(b) requires
    consideration of the land in context, and not in isolation on a parcel-by-parcel
    basis. See Cohen § 3.04[2][c][iii], at 194 (stating that a parcel-by-parcel
    -15-
    approach “reads the word ‘communities’ out of the statute and increases the
    possibility of checkerboard jurisdiction”).
    B . V enetie
    The majority concludes that the Supreme Court’s decision in Venetie
    forecloses a community-of-reference analysis. I disagree.
    A brief discussion of the factual background of Venetie elucidates what the
    Court did and did not decide in that case. In Venetie, the Native Village of
    Venetie Tribal Government sought to tax a private contractor and the State of
    Alaska, who were joint venturers in the construction of a public school on a
    specific parcel of land in the village of Venetie. 522 U.S. at 523. Venetie and
    another neighboring village had been part of a reservation established in 1943 for
    the Neets’aii Gwich’in Indians. Id. at 523. In 1971, however, Congress enacted
    the Alaska Native Claims Settlement Act (ANCSA), which “revoked the various
    reserves set aside . . . for Native use” and extinguished all native claims to Alaska
    land.7 Id. at 524 (citing 
    43 U.S.C. §§ 1603
    , 1618(a)) (quotations omitted). As
    compensation, Congress authorized the transfer of $962.5 million and 44 million
    acres of Alaska land to state-chartered private business corporations. 
    Id.
     Under
    7
    There was one exception to the revocation of the reserves, see 
    43 U.S.C. § 1618
    (a), but that exception was not relevant to the issue in Venetie.
    -16-
    the ANCSA, the shareholders of these corporations had to be Alaska Natives. 
    Id.
    The land issued to these corporations was transferred in fee simple, with no
    restrictions on subsequent transfers of the land. 
    Id.
     Two such corporations were
    formed for the Neets’aii Gwich’in, and the federal government, pursuant to the
    ANCSA, conveyed fee simple title to the land previously constituting the Venetie
    Reservation to those corporations as tenants in common. 
    Id.
    The Court of Appeals for the Ninth Circuit applied a six-factor balancing
    test to determine whether the former-reservation lands constituted a dependent
    Indian community, and thus was subject to taxation by the tribe for work
    performed in the community by non-Indian members. State of Alaska ex rel.
    Yukon Flats Sch. Dist. v. Native Village of Venetie Tribal Gov’t, 
    101 F.3d 1286
    ,
    1294 (9th Cir. 1996). After applying this test, the Ninth Circuit concluded that
    the lands were both set aside and superintended by the federal government, and
    that the land was therefore Indian country under 
    18 U.S.C. § 1151
    (b). 
    Id. at 1302
    .
    The Supreme Court reversed. Rejecting the multi-factor balancing test
    employed by the Ninth Circuit to determine whether the land was set aside and
    superintended as a dependent Indian community, the Court held that § 1151(b)
    “refers to a limited category of Indian lands that are neither reservations nor
    allotments, and that satisfy two requirements— first, they must have been set aside
    by the Federal Government for the use of the Indians as Indian land; second, they
    must be under federal superintendence.” Venetie, 522 U.S. at 527.
    -17-
    Applying this test, the Court concluded that neither requirement was met.
    As to the set-aside requirement, the ANCSA explicitly “revoked all existing
    reservations in Alaska ‘set aside by legislation or by Executive or Secretarial
    Order for Native use,’” and so the land was not currently set aside for Native use.
    Id. at 532 (quoting 
    43 U.S.C. § 1618
    (a)). The land also did not meet the federal
    superintendence requirement, as the ANCSA was intended to forestall a “lengthy
    wardship or trusteeship,” 
    43 U.S.C. § 1601
    (b), and thus ended any
    superintendence of the lands. Venetie, 
    522 U.S. at 533
    . Accordingly, the Tribe’s
    lands did not constitute a dependent Indian community, and hence did not
    constitute Indian country, within the meaning of 
    18 U.S.C. § 1151
    (b).
    Section 1151(b) uses three criteria to define Indian country: (1) it must be
    dependent; (2) it must be Indian; and (3) it must be a community. Venetie
    provides the criteria for determining whether an area of land satisfies (1) and (2):
    (1) the land is “dependent” if it is under federal superintendence, and (2) the land
    is “Indian” if it has “been set aside by the Federal Government for the use of the
    Indians as Indian land.” Venetie, 522 U.S. at 527. Yet the Venetie Court did not
    address the third criteria: determining whether the land in question is a
    community. The set-aside and superintendence requirements address only the
    dependent and Indian character of the “land in question.”
    The “community” requirement determines what area of land constitutes “the
    land in question.” That question was not addressed specifically in Venetie other
    -18-
    than to accept, without discussion, that it was the entire land formerly constituting
    the Neets’aii Gwich’in reservation before it was extinguished. In the present
    case, the majority views HRI’s quarter of Section 8 as the “land in question.”
    One would therefore expect, if it were following the majority’s analysis, that the
    Venetie Court would have narrowly considered whether just the land on which the
    school was to be built was a dependent Indian community. But the Court
    decidedly did not do so. Instead, the Court in Venetie looked at all of the land
    that previously composed the Venetie Reservation— not just the site of the
    proposed school— to determine whether that land constituted a dependent Indian
    community. Venetie, 
    522 U.S. at 523
     (“In this case, we must decide whether
    approximately 1.8 million acres of land in northern Alaska, owned in fee simple
    by the Native Village of Venetie Tribal Government pursuant to the [ANCSA], is
    ‘Indian country.’”) (emphasis added); see also 
    id. at 532
     (“The Tribe’s ANCSA
    lands do not satisfy either of these requirements.”). Therefore, based solely on
    the words “land in question,” which are employed to refer to a broad area of land
    encompassing the narrow strip of land directly in dispute in Venetie, the majority
    overturns a long history of Tenth Circuit authority that requires a separate
    determination of the appropriate community.
    I agree with the majority that Venetie abrogated the multi-factor test for
    determining whether a given community is a dependent Indian community. See
    HRI II, 
    562 F.3d at 1262
     (“Venetie . . . altered the second step of the W atchman
    -19-
    inquiry.” (citing HRI I, 
    198 F.3d at 1248
    )). However, Venetie simply did not
    discuss the first step of the W atchman analysis, namely, how the appropriate
    community is to be defined. At best, Venetie endorsed the application of its two-
    part requirement of set-aside and superintendence to a broader community of
    reference than just the isolated parcel where the dispute is situated. At worst,
    Venetie simply does not address the issue of whether a community of reference
    should first be determined. However, the one thing that cannot be concluded
    from Venetie is that it abrogated the Tenth Circuit’s long-standing community-of-
    reference test to determine the relevant community to which the set-aside and
    superintendence factors are then applied in order to determine whether the
    community is a dependent Indian community.
    C . O ther interpretations of V enetie
    Today’s decision brings this circuit into conflict with the leading treatise in
    the field. According to Professor Cohen’s treatise, the interpretation of § 1151(b)
    that focuses solely on the narrow parcel under inquiry “reads the word
    ‘communities’ out of the statute and increases the possibility of checkerboard
    jurisdiction.” Cohen 3.04[2][c][iii], at 194. Furthermore,
    [t]he Court’s decision in Venetie explicitly approved factors that
    appear to allow consideration of an entire community, so that fee
    lands might be considered part of a dependent Indian community:
    “[T]he degree of federal ownership of and control over the area, and
    the extent to which the area was set aside for the use, occupancy, and
    protection of dependent Indian peoples.”
    -20-
    Id. (quoting Venetie, 
    522 U.S. at
    531 n.7) (emphasis added). Cohen thus adopts
    the more natural reading of “dependent Indian communities” and concludes, as
    would I, that “patented parcels of land and rights-of-way may also be within
    Indian country if they are within a dependent Indian community.” Id. at 195.
    The majority cites two cases from our sister circuits that it claims support
    its position. Upon closer review, however, these opinions do not address the
    community-of-reference question with which we are presented here. First, in
    Blunk v. Arizona Department of Transportation, 
    177 F.3d 879
     (9th Cir. 1999), the
    Navajo Nation purchased land (the “Navajo Fee Land”), ten miles from the
    Navajo reservation, from a private owner, and leased a portion of that land to a
    non-Indian who erected billboards on the land. 
    Id. at 880
    . W hen the state
    required the lessee to obtain a permit for his billboards, the lessee filed suit in
    federal court seeking a declaratory judgment that state regulation of the billboards
    was preempted by federal law and Navajo sovereignty. 
    Id. at 881
    . In considering
    whether the Navajo Fee Land was “Indian country” so that preemption may
    preclude the state’s regulation of the land, the Ninth Circuit concluded that
    “Venetie controls our decision.” 
    Id. at 883
    . “The Navajo Fee Land is neither
    within the Navajo reservation nor is it an Indian allotment. The Navajo Fee Land
    is not a dependent Indian community because the land was purchased in fee by the
    Navajo Nation rather than set aside by the Federal Government.” 
    Id. at 883-84
    .
    Additionally, the federal government did not “exercise any . . . level of
    -21-
    superintendence over the Navajo Fee Land.” 
    Id. at 884
    .
    Blunk, however, did not consider the threshold question presented here:
    namely, whether § 1151(b) requires that the court determine the appropriate
    community of reference before applying the Venetie requirements. To the extent
    Blunk is relevant to this case, it supports our conclusion, for the Blunk court did
    not consider whether the narrow billboard leasehold— what HRI would label the
    “land in question”— was a dependent Indian community by itself, but rather
    whether the entire Navajo Fee Land, of which Blunk had only leased a portion,
    constituted such a community. See Blunk, 
    177 F.3d at 883
     (“The Navajo Fee
    Land is not a dependent Indian community . . . .”). The most that could be
    gleaned from Blunk is that the Ninth Circuit did not consider whether a threshold
    requirement to determine a “community of reference” survived Venetie. At worst
    (from HRI’s perspective), Blunk is contrary to its position here in the present
    appeal.
    In addition, the facts of our case bear little resemblance to those in Blunk.
    W hereas 78% of the Church Rock Chapter is owned by the federal government in
    trust for either the Navajo Nation or individual Navajos, the tribe purchased the
    land in Blunk and owned title to it. In fact, Blunk is consistent with Tenth Circuit
    precedent. In a pre-Venetie case, this court concluded, as the Ninth Circuit did in
    Blunk, that land purchased and owned by a tribe in fee simple outside the
    reservation and not otherwise a part of a dependent Indian community was not
    -22-
    Indian country merely by virtue of its tribal ownership, because the land was
    neither set-aside nor superintended by the federal government. Buzzard v. Okla.
    Tax Comm’n, 
    992 F.2d 1073
    , 1076 (10th Cir. 1993). Blunk therefore should not
    inform this court’s analysis of a community of land that is predominantly owned
    by the federal government rather than the tribe.
    In the second case cited by the majority, the Eighth Circuit held that 174.57
    acres of land acquired by the United States in trust on behalf of the tribe was a
    dependent Indian community because it met both the set-aside and
    superintendence requirements. Yankton Sioux Tribe v. Podhradsky, 
    577 F.3d at 970-71
    . It does not appear that the parties in that case contested that the entire
    acreage at issue constituted the appropriate community of reference, and so the
    case provides no guidance on whether such an inquiry is precluded by Venetie.
    This case is also inapt because, in this circuit, “‘lands held in trust by the United
    States for the Tribes are Indian Country within the meaning of § 1151(a)’” as
    informal reservations, and thus need not be analyzed under § 1151(b) at all. HRI
    I, 
    198 F.3d at 1254
     (quoting Cheyenne-Arapaho Tribes v. Okla., 
    618 F.2d 665
    ,
    668 (10th Cir. 1980)). The majority therefore has not cited to a single court of
    appeals case after Venetie that rejects a community-of-reference approach to
    determining the existence of a dependent Indian community.
    The majority states that it is “unclear how these courts could have
    conducted a proper § 1151(b) analysis without” the community of reference test if
    -23-
    that is an essential threshold test. M aj. op. at 73 n.29. But neither case presented
    a situation where such a threshold test was required, and thus the holdings of
    those cases necessarily say nothing about the propriety of such a test. I cannot
    agree with the inference drawn by the majority that, by omitting any mention of a
    community-of-reference test, those courts must have precluded the application of
    such a test.
    The majority also cites to a decision by the New M exico Supreme Court
    which does directly address the community-of-reference test and concludes that
    the test does not apply. See State v. Frank, 
    52 P.3d 404
    , 409 (N.M . 2002) (“In
    light of the clear guidelines in the Venetie opinion, we decline to incorporate a
    community of reference inquiry into our case law.”). However, that court may
    have misinterpreted our community-of-reference test as comprising some of the
    balancing factors disapproved by Venetie rather than simply as an effort to
    determine the appropriate community of reference in §1151(b) to which to apply
    the Venetie test. See id. at 409. Further, the court in Frank did not directly
    address the arguments advanced here, including the statutory interpretation and
    policy arguments, and that Venetie addressed a factual situation that did not
    involve consideration of the appropriate community of reference.
    In addition, four years later, the New M exico Supreme Court appeared to
    qualify Frank’s holding by recognizing that “the fee land within a § 1151(b)
    dependent Indian community is Indian country just like the fee land within a §
    -24-
    1151(a) reservation.” State v. Romero, 
    142 P.3d 887
    , 895 (N.M . 2006).
    Admittedly, the land at issue in Romero was within a pueblo. Nevertheless, the
    court endorsed a larger community approach to determining whether privately-
    owned fee land within the pueblo is a dependent Indian community, and it
    rejected the argument “that we should look only to the parcels of private fee land,
    rather than the whole pueblo.” 
    Id. at 892
    . The court further noted that
    “[c]onsidering the pueblo as a whole is also consistent with congressional intent
    in enacting § 1151 because it discourages checkerboarding,” id., which, of course,
    is one of the primary arguments for retaining the community-of-reference analysis
    in § 1151(b) as introduced in W atchman. Thus, the New M exico Supreme Court
    treated all of the land within the pueblo, including privately-held land, as the
    “land in question” for purposes of applying the Venetie factors. Id. Accordingly,
    the New M exico Supreme Court recognizes that land within a dependent Indian
    community can be Indian country under § 1151 even though the specific parcel of
    land at issue is privately-owned in fee by non-Indians.
    This New M exico case law is therefore not particularly illuminating, both
    because “we [are not] bound by a state court’s interpretation of federal law,”
    W ilder v. Turner, 
    490 F.3d 810
    , 814 (10th Cir. 2007), and because, in light of
    Romero, it is not clear that the holding of Frank is still valid even in New M exico
    courts.
    D.     A pplication to Section 8
    -25-
    1.     C om m unity of reference
    Therefore, I conclude that a court considering whether a piece of land
    constitutes a dependent Indian community under 
    18 U.S.C. § 1151
    (b) should
    engage in a two-step process. First, when the area proposed as a community is
    disputed, the court must determine the appropriate community of reference.
    Second, the court must apply the two Venetie factors to that community to
    determine whether that community is dependent and Indian. The community will
    thus constitute a dependent Indian community only if it was set aside for the use
    of the Indians and is under the superintendence of the federal government.
    Venetie, 
    522 U.S. at 531-32
    .
    Determining the appropriate community of reference requires three steps.
    First, the court (or agency) must determine whether the proposed community has
    reasonably ascertainable boundaries. See Adair, 
    111 F.3d 770
    , 774 (10th Cir.
    1997); see also Cohen (1982), Ch. 1 § D3c, at 39 (“[T]he statute intended to
    include only Indian communities with reasonably defined boundaries . . . .”).
    Next, the court must determine whether the land within those boundaries
    possesses a reasonable degree of coherence such that the land is logically treated
    as a community. Finally, the court should look at whether the uses to which the
    land is put and the people inhabiting the land possess a reasonable degree of
    coherence. If the area of land has reasonably ascertainable boundaries and the
    land possesses a reasonable degree of cohesiveness, then it is an appropriate
    -26-
    community for the purpose of determining whether it is a dependent Indian
    community under 
    18 U.S.C. § 1151
    .
    As articulated above, community, as used in § 1151(b), implies context.
    W hile Venetie did not address how to determine the appropriate community of
    reference, it did make clear that the status of the land within the alleged
    community plays an important role in determining whether the land is part of a
    dependent Indian community. See Venetie, 
    522 U.S. at
    530 n.5. Therefore, I
    initially consider the extent to which the land itself shares common features.
    First, the hydrology of the Section 8 land is directly tied into the hydrology
    of the entire Church Rock Chapter. Three separate aquifers— the W estwater
    Canyon Aquifer, the Cow Springs Aquifer, and the Dakota Sandstone
    Aquifer— all run directly underneath the Section 8 land and throughout the
    Chapter. As of 1998, fourteen wells from the W estwater Canyon Aquifer— from
    which the Chapter residents predominately draw their drinking water— were
    within twenty miles of Section 8. The water from those wells meets primary
    SDW A standards, and the Branch M anager of the W ater M anagement Branch of
    the Navajo Nation Department of W ater Resources characterized the W estwater
    Canyon water as “outstanding.” (R. doc. 13b at 252.) This common hydrology
    throughout the Chapter makes it difficult for any activities that affect the
    groundwater carried out on Section 8 land to be limited to that parcel. (R. doc. 40
    at B-3 (“W estwater Canyon . . . has some of the area’s groundwater and most of
    -27-
    its uranium deposits.”).) Rather, any pollution into the aquifers would likely
    affect much of the Chapter population.
    In addition, the land throughout the Church Rock Chapter is connected
    based on its history and usage. Cf. Venetie, 522 U.S. at 523-24 (discussing
    history of the Neets’aii Gwich’in lands). The land in the Church Rock Chapter is
    predominately devoted to livestock grazing; in fact, the portion of HRI-owned
    land within Section 8 is surrounded on all four sides by grazing land used by
    members of the Chapter. Grazing exists on Section 8 land, pursuant to BIA-
    issued grazing permits, in a manner that is integrated with the surrounding areas
    of the Chapter. For instance, Grazing Permit Number 7 contiguously covers over
    half of Section 8, all of Section 9, and half of Section 16, as well as a portion of
    Section 17; Grazing Permit Number 8 also covers part of Section 8, and extends
    south into Section 17. This demonstrates that Section 8’s land is in no way
    distinct from the lands surrounding it and it is fully integrated in the land’s
    history of supporting a livestock-based economy. From the standpoint of the
    characteristics of the land, then, Section 8 is part of the community of land in the
    Church Rock Chapter.
    Although Venetie emphasized the importance of considering the land, it did
    not foreclose consideration of other factors for purposes of determining the
    community of reference. Indeed, while the word “community” can refer to the
    area in which a well-defined group of people lives, the word also refers to the
    -28-
    group of people themselves. See W ebster’s Third New International Dictionary
    460 (1986) (defining community as “a body of individuals organized into a unit or
    manifesting [usually] with awareness some unifying trait”). Consideration of the
    people who live within the Church Rock Chapter further shows that the Chapter is
    properly considered a single community. Based on the 2000 census, 97.7% of the
    2,802 residents of the Chapter are Indian, and most of the remaining sixty-five
    residents are married to Navajos. A majority of the residents speak Navajo. In
    addition to a common heritage, residents of Church Rock remain closely tied to
    the Chapter. 88% of the residents of Church Rock go to the Chapter House at
    least monthly, further underscoring the sense of community throughout the
    Chapter. Finally, through the Chapter House, the residents receive a variety of
    services, including a Head Start program, community health care, housing
    assistance, work programs, utility line extensions, and a food distribution center.
    Therefore, on the basis of these various indicators, I would conclude that
    the Church Rock Chapter, rather than Section 8 itself, is the appropriate
    community of reference. This analysis gives effect to the intent of Congress
    embodied in § 1151 to avoid checkerboard jurisdiction. See Seymour, 
    368 U.S. at 358
     (stating that Congress intended to avoid “an impractical pattern of
    checkerboard jurisdiction . . . by the plain language of § 1151”). “[T]he full
    statute was intended to reduce earlier difficulties which had arisen from the
    ‘checkerboarding’ of land ownership and rights-of-way.” Cohen (1982), Ch. 1 §
    -29-
    D3c, at 39. Consideration of whether a community qua community, rather than an
    individual tract of land, is Indian country gives meaning to the word
    “communities” in the statute, and limits the undesirable outcome where
    jurisdiction changes every mile.
    The unfortunate consequences of the majority’s opinion are made especially
    clear by the facts of this case. HRI seeks to operate a mine on portions of Section
    8 and the adjoining Section 17. As Section 17 is trust land, however, it is
    unquestionably Indian country under 
    18 U.S.C. § 1151
    (a) and subject to EPA’s
    jurisdiction for SDW A purposes. Now, under the majority’s opinion, passing the
    invisible boundary between Section 17 and 8 transfers jurisdiction from EPA to
    NM ED, despite the continuous mining operation and the shared aquifer between
    the two parcels (as well as the rest of the Chapter). Section 1151 sought to avoid
    such a jurisdiction-by-tractbook approach in the realm of criminal jurisdiction,
    and the EPA reasonably adopted the same standard to apply for purposes of
    SDW A jurisdiction.
    The majority’s extended discussion of the difficulties that would arise in
    administering a community-of-reference test overlooks one simple fact:
    community-of-reference has been the law in this circuit for the last twenty years.
    Outside of some conclusory and unsupported assertions offered by the states in
    their amicus brief, the parties have not called to our attention any significant
    problems that this test has caused. To the contrary, it is the majority that is
    -30-
    casting off into uncharted waters, and while the community-of-reference test has
    caused no significant difficulties of which I am aware, the real-world implications
    of the majority’s new approach are, quite frankly, unknown. Indeed, the
    relatively few cases seen by this court over the last two decades concerning
    confusion over the appropriate community of reference is strong circumstantial
    evidence that the test in fact works well.
    2.     T he V enetie factors
    Having established Church Rock Chapter as the appropriate community of
    reference, I would then apply Venetie’s set-aside and superintendence
    requirements to determine if the Chapter constitutes a dependent Indian
    community. Upon examination, both requirements are easily met.
    In order for a community to satisfy the set-aside requirement, “the Federal
    Government must take some action setting apart the land for the use of the
    Indians ‘as such.’” Venetie, 
    522 U.S. at
    530 n.5.; 
    id.
     at 531 n.6 (“The federal set-
    aside requirement also reflects the fact that . . . some explicit action by Congress
    (or the Executive . . . ) must be taken to create or to recognize Indian country.”).
    Here, the government purchased several parcels in the area from the Santa Fe
    Pacific Railroad Company in the late 1920s. See HRI II, 
    562 F.3d at
    1254 n.3.
    The government placed much of that land in trust for the Navajos and allotted the
    rest to individual Navajos. 
    Id. at 1252
    . The government has set aside 78% of the
    land in the Chapter for the use of Indians either as trust land either for the tribe or
    -31-
    for individuals in the form of allotments, and BLM owns an additional 10% of the
    land, for which grazing permits are granted to Navajos. Considering the Chapter
    as the community, then, the Chapter has been set aside by the federal government
    for the use of the Navajo.
    The Chapter also satisfies the federal superintendence requirement.
    “Superintendency over the land requires the active involvement of the federal
    government.” Buzzard, 
    992 F.2d at 1076
    ; see also Venetie, 
    522 U.S. at 533
    (noting that, in past cases that found federal superintendence, “the Federal
    Government actively controlled the lands in question, effectively acting as a
    guardian for the Indians”). In M cGowan, for example, the Court found
    superintendence where the federal government “retains title to the lands which it
    permits the Indians to occupy” and where the federal government “has authority
    to enact regulations and protective laws respecting this territory.” 
    302 U.S. at 539
    ; see also United States v. Roberts, 
    185 F.3d 1125
    , 1132-33 (10th Cir. 1999);
    Buzzard, 
    992 F.2d at 1076
    .
    In the form of tribal trust land, allotments, or land owned by BLM , the
    federal government retains title to 92% of the land in the Chapter, and as title
    owner certainly retains superintendence over the land. In addition, EPA found
    that DOI supervises natural resources in the Chapter, and BIA supervises land
    use, issues grazing permits, “protect[s] Navajo Nation trust lands, natural
    resources, and water rights, and administer[s] various trust benefits on behalf” of
    -32-
    the Chapter. (R. doc. 44 at 12.) Thus, not only does the federal government
    possess “authority to enact regulations and protective laws” in the Chapter, it
    frequently acts on that authority. M cGowan, 
    302 U.S. at 539
    . Indeed, as the
    Navajo Nation noted, “[t]here is no significant difference in the way the United
    States interacts with the Church Rock Chapter [and] the way it interacts with
    Chapters located in the Navajo Reservation proper,” and reservations are under
    federal superintendence. (R. doc. 13a at 13.) The Chapter therefore is under
    federal superintendence.
    III.         C onclusion
    In my view, the Church Rock Chapter is the appropriate community of
    reference. As the Chapter satisfies both of the criteria identified in Venetie, I
    would conclude that HRI’s Section 8 land is within a dependent Indian
    community and affirm the panel’s decision.
    The lengthy opinions generated by this case and the division within this
    court as to the proper interpretation of 
    18 U.S.C. § 1151
    (b) attest to the confusion
    surrounding this area of the law. This confusion is unfortunate, and the
    consequences are likely to be enormous, reintroducing checkerboard jurisdiction
    into the southwest on a grand scale and disrupting a field of law that had been
    settled for decades. In overturning our community-of-reference test, the majority
    today reaches a result not compelled by either Supreme Court or Tenth Circuit
    -33-
    precedent. Before all is said and done, this confusion and the serious
    consequences generated by today’s opinion may ultimately require resolution by
    the Supreme Court.

    Hydro Resources, Inc. v. United States Environmental Protection Agency,
    No. 07-9506
    H E N R Y , Circuit Judge, joined by B R ISC O E, Chief Judge, L U C E R O , Circuit
    Judge, dissenting.
    In this case, we must determine who regulates ground water injections
    containing radioactive substances on a tract of land surrounded by an Indian
    community. The majority holds that because the individual tract at issue was
    neither (a) “‘set aside’ by Congress (or the Executive, acting under delegated
    authority ‘for the use of the Indians as Indian land[;]’” nor (b) “‘dependent’ in the
    sense that it is ‘under federal superintendence,’” it is not part of a dependent
    Indian community under 
    18 U.S.C. § 1151
    (b). M aj. op. at 4-5 (quoting Alaska v.
    Native Vill. of Venetie Tribal Gov’t, 
    522 U.S. 520
    , 527, 531 (1998)).      Judge
    Ebel’s well-crafted and well-reasoned dissent, which I join, applies the well-
    established community-of-reference standard, concludes that the Church Rock
    Chapter is the appropriate community of reference, and holds that the land at
    issue is within that dependent Indian community. As a result, in the dissent’s
    view, the land at issue is subject to federal environmental regulations.
    I write separately to underscore the major concerns that I have with the
    majority opinion–which I fear undoes decades of settled Indian law based upon
    sound principles. First, in my view, it is the majority, not the dissent, that fails to
    tie “the jurisdictional determination to the proper hitch: the will of Congress.”
    M aj. op. at 46-47. Second, the Supreme Court’s decision in United States v.
    M azurie, 
    419 U.S. 544
    , 551 (1975), which remains good law after Venetie,
    supports the community-of-reference approach. Third, Venetie itself, the Supreme
    Court case on which the majority grounds its rejection of the community-of-
    reference inquiry, did not involve non-Indian fee land surrounded by an Indian
    community and thus does not resolve the question before us. Fourth, I am not
    convinced that principles regarding the construction of criminal statutes should be
    applied here. Finally, and perhaps most importantly, the majority’s approach
    conflicts with one of the central purposes of the statute at issue–to avoid
    checkerboard jurisdiction.
    In 
    18 U.S.C. § 1151
    (b), Congress used the word “communities.” A
    community is “a social group of any size whose members reside in a specific
    locality, share government, and have a common cultural and historic heritage.”
    Webster’s New Universal Unabridged Dictionary, at 298 (1989); see also Dissent
    at 8 (observing that the term “community” “implies the existence of some setting
    within which the property in question is to be evaluated”). Accordingly, in
    conducting a community-of-reference analysis that extends beyond the status of a
    particular parcel of land, it is the dissent and the panel opinion that are more
    firmly rooted in the words used by Congress.
    As Judge Ebel also observes, the community-of-reference standard is
    supported by the Supreme Court’s decision in M azurie, 
    419 U.S. at 551
    . There,
    in rejecting the contention that a non-Indian tract was part of “a non-Indian
    -2-
    community” under 
    18 U.S.C. § 1154
    (b) (emphasis added), the Court considered
    the area within the W ind River Reservation that surrounded that tract. 1 See 
    id.
    (discussing evidence regarding “the 20-square-mile area roughly centered on [the
    non-Indian tract]”). The majority seeks to distinguish M azurie on the grounds
    that “[a]lthough the terms ‘non-Indian communities’ and ‘dependent Indian
    communities’ both concern ‘communities,’ they deal with markedly different
    types of communities.” M aj op. at 59 n.20. I find that distinction unsatisfying.
    Surely, when Congress uses the same term in two related statutes, and when the
    widely accepted use of that term suggests context, see Dissent at 8-9, we ought to
    apply the same definition unless there are particularly persuasive reasons not to
    do so. Here, I see no such reasons.
    In particular, Venetie does not require us to abandon our established
    community-of- reference test with regard to the Section 8 land here at issue.
    Venetie did not involve land owned by a non-Indian mining corporation in fee
    simple located in the midst of trust land and allotments that constitute “Indian
    country” under the other subsections of § 1151. Thus, the Supreme Court’s
    1
    That statute prohibits the introduction of “any malt, spirituous, or vinous
    liquor, including beer, ale, and wine, or any ardent or intoxicating liquor of any
    kind whatsoever into the Indian country.” 
    18 U.S.C. § 1154
    (b). It further
    provides that “[t]he term ‘Indian country’ as used in this section does not include
    fee-patented lands in non-Indian communities or rights-of-way through Indian
    reservations, and this section does not apply to such lands or rights-of-way in the
    absence of a treaty or statute extending the Indian liquor laws thereto.” 
    18 U.S.C. § 1154
    (c).
    -3-
    decision does not tell us which particular lands we must consider in determining
    whether the set-aside and superintendence requirements have been met.
    Additionally, I am not persuaded by the majority’s view that our
    interpretation of the statute “will apply to all criminal cases arising under §
    1151(b).” M aj. op. at 63. The EPA adopted § 1151’s definition of “Indian
    country” in the course of administering the Safe Drinking W ater Act. M oreover,
    as Judge Ebel reasons, the concept of community should be afforded heightened
    importance in the natural resources context. See Dissent at 15. It is that context
    that we consider here. I would leave the implications of our holding for
    hypothetical criminal prosecutions, if any, for actual cases in which prosecutions
    are brought regarding conduct in dependent Indian communities.
    Further, I must take exception to the majority’s view that because some
    degree of checkerboard jurisdiction is inevitable in the application of § 1151, we
    may veer away from that fundamental concern in applying the concept of a
    dependent Indian community to the facts of this case. Leading Indian law
    scholars have told us that “a central purpose of the 1948 codification [of § 1151]
    was to avoid checkerboard jurisdiction.” See Felix S. Cohen, Handbook of
    Federal Indian Law § 3.04[2][c][iv], at 194 n.429 (2005 ed.) (citing Seymour v.
    Superintendent of Wash. State Penitentiary, 
    368 U.S. 351
    , 358 (1962)). I think
    we ought to listen to them, particularly when a non-Indian land owner proposes a
    mining operation that affects the surrounding community. In that circumstance, it
    -4-
    makes good sense to treat Section 8 as part of that community and to require the
    mining operation to comply with federal law.
    I take little comfort in the majority’s observation that, in the EPA’s
    judgment, the aquifer under HRI’s land “‘does not currently serve as a source of
    drinking water’” and “‘cannot now and will not in the future serve as a source of
    drinking water.’” M aj. op. at 17 (quoting 
    40 C.F.R. § 146.4
    (a) & (b)). Even if
    that is true in this case, there are other effects of a mining operation that may
    greatly impact the surrounding lands. See Dissent at 15 (noting that “[t]he
    externalities produced by a mining operation— including pollution, traffic, and the
    aesthetic harms created by having a large mining operation nearby— also affect
    the surrounding community”).
    M oreover, as one scholar has noted, previous mining operations in the area
    at issue have had grave consequences: “[t]he tailings from uranium mines have
    contaminated air, groundwater, streams and soil on the Navajo reservation. The
    wind blew dust from the tailings piles into Navajo homes and water sources.
    Holding ponds on the reservation associated with the uranium mines were not
    well-maintained. In 1979, a mud dam near Church Rock, New M exico[,] failed,
    spilling over 1,100 tons of uranium tailings, and an estimated 100 million gallons
    of radioactive wastewater into the Rio Puerco River. This is the largest nuclear
    spill in U.S. history, and it caused extensive damage to the Navajo people, their
    lands, water resources and the livestock that drank the contaminated water.” See
    -5-
    Rebecca Tsosie, “Climate Change, Sustainability, and Globalization: Charting the
    Future of Indigenous Environmental Self-Determination,” 4 Envtl. & Energy L. &
    Pol’y J. 188, 220 (2009).
    As I understand it, under the rule announced by the majority, a uranium
    mine located on non-Indian land but surrounded by land that constitutes a
    dependent Indian community would not be subject to federal regulation. I fail to
    see how such a rule comports with the applicable statute, the case law, or the
    federal government’s “distinctive obligation of trust . . . in its dealings with these
    dependent and sometimes exploited people.” M orton v. Ruiz, 
    415 U.S. 199
    , 236
    (1974) (internal quotation marks omitted).
    The proper standard for identifying a dependent Indian community under 
    18 U.S.C. § 1151
    (b) is a matter of utmost importance to Indian tribes, the states, and
    the federal government. I would affirm the EPA’s determination and the panel’s
    ruling, and I must dissent from the majority’s contrary conclusion. Additionally,
    in light of the disagreement among my colleagues, the continuing uncertainty in
    other courts about the proper application of Venetie in checkerboard areas like
    those at issue here, and the serious consequences of abandoning our well-
    established community-of-reference approach, I agree with Judge Ebel that a
    resolution of this issue by the United States Supreme Court is warranted.
