    SUMMARY*
    Mining Law / Preemption
    Affirming the district court’s summary judgment in favor
    of defendants, the panel held that mining restrictions set forth
    in Oregon Senate Bill 3 are not preempted by federal law.
    To protect threatened fish populations, Senate Bill 3
    prohibits the use of motorized mining equipment in rivers and
    streams containing essential salmon habitat. The restrictions
    apply throughout the state, including on rivers and streams
    located on federal lands. Plaintiffs have mining claims on
    federal land in Oregon.
    Assuming without deciding that federal law preempts the
    extension of state land use plans onto unpatented mining
    claims on federal land, the panel held that Senate Bill 3 is not
    preempted because it constitutes an environmental regulation,
    not a state land use planning law. In addition, Senate Bill 3
    does not stand as an obstacle to the accomplishment of the
    full purposes and objectives of Congress. The panel
    concluded that reasonable state environmental restrictions
    such as those found in Senate Bill 3 are consistent with, rather
    than at odds with, the purposes of federal mining and land use
    laws. The panel held that Senate Bill 3 therefore is neither
    field preempted nor conflict preempted.
    Dissenting, Judge N.R. Smith wrote that the National
    Forest Management Act and the Federal Land Policy and

    Management Act occupy the field of land use planning
    regulation on federal lands. He wrote that because the
    permanent ban on motorized mining in Oregon Senate Bill 3
    does not identify the environmental standard to be achieved
    but instead restricts a particular use of federal land, it must be
    deemed a land use regulation preempted by federal law.

    OPINION
    FISHER, Circuit Judge:
    To protect threatened fish populations, Oregon prohibits
    the use of motorized mining equipment in rivers and streams
    containing essential salmon habitat. The restrictions, adopted
    into law as Senate Bill 3, apply throughout the state,
    including on rivers and streams located on federal lands. The
    district court concluded the restrictions are not preempted by
    federal law, and we agree. Assuming without deciding that
    federal law preempts the extension of state land use plans
    onto unpatented mining claims on federal lands, Senate Bill 3
    is not preempted, because it constitutes an environmental
    regulation, not a state land use planning law. Senate Bill 3,
    moreover, does not stand as an obstacle to the
    accomplishment of the full purposes and objectives of
    Congress. As the United States points out in its amicus brief
    opposing the plaintiffs’ preemption challenge, reasonable
    environmental restrictions such as those found in Senate
    Bill 3 are consistent with, rather than at odds with, the
    purposes of federal mining and land use laws. See Cal.
    Coastal Comm’n v. Granite Rock Co., 
    480 U.S. 572
    , 588–89
    (1987) (rejecting the proposition that federal law preempts
    the application of reasonable state environmental regulations
    to the operation of unpatented mining claims on federal
    lands).
    BACKGROUND
    The Oregon legislature adopted Senate Bill 838 in 2013.
    The Bill’s legislative findings recognize both the state’s rich
    tradition of small scale prospecting and mining and its
    BOHMKER V. STATE OF OREGON                  7
    environmental interest in protecting water quality and fish
    habitat. The findings state:
    (1) Prospecting, small scale mining and
    recreational mining are part of the unique
    heritage of the State of Oregon.
    (2) Prospecting, small scale mining and
    recreational mining provide economic
    benefits to the State of Oregon and local
    communities and support tourism, small
    businesses and recreational opportunities, all
    of which are economic drivers in Oregon’s
    rural communities.
    (3) Exploration of potential mine sites is
    necessary to discover the minerals that
    underlie the surface and inherently involves
    natural resource disturbance.
    (4) Mining that uses motorized equipment in
    the beds and banks of the rivers of Oregon can
    pose significant risks to Oregon’s natural
    resources, including fish and other wildlife,
    riparian areas, water quality, the investments
    of this state in habitat enhancement and areas
    of cultural significance to Indian tribes.
    (5) Between 2007 and 2013, mining that uses
    motorized equipment in the beds and banks of
    the rivers of Oregon increased significantly,
    raising concerns about the cumulative
    environmental impacts.
    8            BOHMKER V. STATE OF OREGON
    (6) The regulatory system related to mining
    that uses motorized equipment in the beds and
    banks of the rivers of Oregon should be
    efficient and structured to best protect
    environmental values.
    2013 Or. Laws ch. 783, § 1.
    Consistent with these findings, the law imposed a five-
    year moratorium, beginning in 2016, on motorized mining
    techniques in areas designated as essential fish habit:
    A moratorium is imposed until January 2,
    2021, on mining that uses any form of
    motorized equipment for the purpose of
    extracting gold, silver or any other precious
    metal from placer deposits of the beds or
    banks of the waters of this state, as defined in
    ORS 196.800, or from other placer deposits,
    that results in the removal or disturbance of
    streamside vegetation in a manner that may
    impact water quality. The moratorium applies
    up to the line of ordinary high water, as
    defined in ORS 274.005, and 100 yards
    upland perpendicular to the line of ordinary
    high water that is located above the lowest
    extent of the spawning habitat in any river and
    tributary thereof in this state containing
    essential indigenous anadromous salmonid
    habitat, as defined in ORS 196.810, or
    naturally reproducing populations of bull
    trout, except in areas that do not support
    populations of anadromous salmonids or
    natural reproducing populations of bull trout
    BOHMKER V. STATE OF OREGON                          9
    due to a naturally occurring or lawfully placed
    physical barrier to fish passage.
    Id. § 2(1). “‘Essential indigenous anadromous salmonid
    habitat’ means the habitat that is necessary to prevent the
    depletion of indigenous anadromous salmonid species during
    their life history stages of spawning and rearing.” 
    Or. Rev. Stat. § 196.810
    (1)(g)(B).
    The plaintiffs filed this action in October 2015, three
    months before the moratorium was to take effect. The
    12 plaintiffs have mining claims on federal lands in Oregon
    and use a form of motorized mining known as suction dredge
    mining to search for and extract gold deposits from rivers and
    streams.1 The plaintiffs alleged that many of their mining
    claims were located in “essential indigenous anadromous
    salmonid habitat” and that the moratorium on motorized
    mining imposed by Senate Bill 838 would prevent them from
    mining these claims. They argued that Senate Bill 838 was
    preempted by federal law because it “interfere[d] with the
    federal purpose of fostering and encouraging mineral
    development on federal property, and st[ood] as an obstacle
    1
    Suction dredging is
    a technique used by miners to remove matter from the
    bottom of waterways, extract minerals, and return the
    residue to the water. A high-powered suction hose
    vacuums loose material from the bottom of a
    streambed. Heavier matter, including gold, is separated
    at the surface by passage through a floating sluice box,
    and the excess water, sand, and gravel is discharged
    back into the waterway.

    377 P.3d 818
    , 820 (Cal. 2016).
    10            BOHMKER V. STATE OF OREGON
    to the accomplishment and execution of the purposes and
    objectives of Congress.” Compl. ¶ 49. The plaintiffs sought
    an injunction restraining the state from enforcing Senate Bill
    838 and a declaration that the Bill was preempted by federal
    law. Compl. 14.
    The district court granted the state’s motion for summary
    judgment, ruling that, because Senate Bill 838 was a
    reasonable environmental regulation, it was not preempted.
    After the court entered judgment in favor of the state, the
    plaintiffs timely appealed.
    After briefing in this court was completed, the Oregon
    legislature adopted Senate Bill 3. Senate Bill 3 repealed the
    moratorium imposed by Senate Bill 838 and imposed a
    permanent restriction on the use of motorized mining
    equipment in waters designated as essential indigenous
    anadromous salmonid habitat. It states:
    In order to protect indigenous anadromous
    salmonids and habitat essential to the
    recovery and conservation of Pacific lamprey,
    motorized in-stream placer mining may not be
    permitted to occur up to the line of ordinary
    high water in any river in this state containing
    essential indigenous anadromous salmonid
    habitat, from the lowest extent of essential
    indigenous anadromous salmonid habitat to
    the highest extent of essential indigenous
    anadromous salmonid habitat.
    2017 Or. Laws ch. 300, § 4(2). Although the restrictions
    imposed by Senate Bill 3 differ in some respects from those
    in Senate Bill 838, both laws prohibit motorized mining in
    BOHMKER V. STATE OF OREGON                            11
    rivers and streams designated as essential salmon habitat.2
    The parties therefore agree that the adoption of Senate Bill 3
    does not moot this appeal. See Ne. Fla. Chapter of the
    Associated Gen. Contractors of Am. v. City of Jacksonville,
    Fla., 
    508 U.S. 656
    , 662 & n.3 (1993) (holding that the repeal
    of a challenged ordinance and its replacement with a different
    ordinance did not render the plaintiff’s claims moot where the
    ordinance had not been “sufficiently altered so as to present
    a substantially different controversy from the one the District
    Court originally decided” and the two ordinances
    “disadvantage[d] [the plaintiff] in the same fundamental
    way”). The parties also agree that we should treat this appeal
    as a challenge to Senate Bill 3. We now proceed to do so.
    JURISDICTION AND STANDARD OF REVIEW
    We have jurisdiction under 
    28 U.S.C. § 1291
    . Because at
    least some of the plaintiffs have standing to pursue this
    appeal, we need not address the standing of additional
    plaintiffs. See Nat’l Ass’n of Optometrists & Opticians
    LensCrafters, Inc. v. Brown, 
    567 F.3d 521
    , 523 (9th Cir.
    2009) (“As a general rule, in an injunctive case this court
    need not address standing of each plaintiff if it concludes that
    one plaintiff has standing.”).3 Our review is de novo. See
    2
    Unlike Senate Bill 838, for example, Senate Bill 3 does not prohibit
    motorized mining in bull trout habitat. In addition, although the
    moratorium imposed by Senate Bill 838 extended to mining in areas up to
    100 yards from waterways, the restrictions on motorized mining in Senate
    Bill 3 apply only within rivers and streams themselves.
    3
    We therefore need not address whether plaintiffs Galice Mining
    District, Millennium Diggers and Willamette Valley Miners have
    established standing, either in their own right or on behalf of their
    members. See Associated Gen. Contractors of Am., San Diego Chapter,
    12              BOHMKER V. STATE OF OREGON
    Lopez-Valenzuela v. Arpaio, 
    770 F.3d 772
    , 777 (9th Cir.
    2014) (en banc) (grant or denial of summary judgment); Ting
    v. AT&T, 
    319 F.3d 1126
    , 1135 (9th Cir. 2003) (federal
    preemption).
    DISCUSSION
    A. Background Legal Principles
    1. Federal Laws Governing Mining on Federal Lands
    We begin with an overview of the federal laws respecting
    mining on federal lands. We consider only those laws the
    parties have identified as relevant to the preemption issues
    presented in this appeal.
    “Historically, the Federal mining law has been designed
    to encourage individual prospecting, exploration, and
    development of the public domain.” H.R. Rep. No. 84-730
    (1955), as reprinted in 1955 U.S.C.C.A.N. 2474, 2476.
    “Under these laws, prospectors may go out on the public
    domain not otherwise withdrawn, locate a mining claim,
    search out its mineral wealth and, if discovery of mineral is
    made, can then obtain a patent.” 
    Id.
    The Mining Act of 1872, 
    17 Stat. 91
    , for example,
    provides that:
    Inc. v. Cal. Dep’t of Transp., 
    713 F.3d 1187
    , 1194 (9th Cir. 2013)
    (explaining that, to establish associational standing, a plaintiff must
    provide specific allegations showing that at least one identified member
    has suffered or would suffer harm).
    BOHMKER V. STATE OF OREGON                   13
    Except as otherwise provided, all valuable
    mineral deposits in lands belonging to the
    United States, both surveyed and unsurveyed,
    shall be free and open to exploration and
    purchase, and the lands in which they are
    found to occupation and purchase, by citizens
    of the United States and those who have
    declared their intention to become such, under
    regulations prescribed by law, and according
    to the local customs or rules of miners in the
    several mining districts, so far as the same are
    applicable and not inconsistent with the laws
    of the United States.
    
    30 U.S.C. § 22
     (emphasis added). Under this Act,
    prospectors could acquire unpatented mining claims by
    discovering valuable mineral resources on federal lands,
    marking the location of their claims and recording their
    claims in accordance with state law:
    Rights to mineral lands, owned by the United
    States, are initiated by prospecting, that is,
    searching for minerals thereon, and, upon the
    discovery of mineral, by locating the lands
    upon which such discovery has been made, or
    lands which the prospector believes to be
    valuable for minerals. A location is made by
    staking the corners of the claim, posting a
    notice of location thereon, and complying
    with the State laws regarding the recording of
    the location in the county recorder’s office,
    discovery work, etc.
    H.R. Rep. No. 84-730, 1955 U.S.C.C.A.N. at 2477.
    14            BOHMKER V. STATE OF OREGON
    Once the prospector staked out a claim, “the locator,
    without further requirement under Federal law, as of that
    moment, acquire[d] the immediate right to exclusive
    possession, control, and use of the land within the corners of
    his location stakes.” 
    Id. at 2478
    . As the Mining Act
    explains:
    The locators of all mining locations made on
    any mineral vein, lode, or ledge, situated on
    the public domain, their heirs and assigns,
    where no adverse claim existed on the 10th
    day of May 1872 so long as they comply with
    the laws of the United States, and with State,
    territorial, and local regulations not in conflict
    with the laws of the United States governing
    their possessory title, shall have the exclusive
    right of possession and enjoyment of all the
    surface included within the lines of their
    locations, and of all veins, lodes, and ledges
    throughout their entire depth . . . .
    
    30 U.S.C. § 26
     (emphasis added). To protect this right to
    exclusive possession, a locator annually must perform $100
    worth of labor or carry out improvements worth $100 in
    value. See 
    id.
     § 28.
    The locator of an unpatented mining claim either “may
    remove the minerals from the land without first proceeding to
    patent,” H.R. Rep. No. 84-730, 1955 U.S.C.C.A.N. at 2478,
    or may obtain a patent by, inter alia, filing an application
    under oath, showing that $500 worth of labor has been
    expended or improvements made with respect to the claim
    and making a payment to the proper officer of $5 per acre,
    see 
    30 U.S.C. § 29
    . Although “[a]n ‘unpatented’ claim is a
    BOHMKER V. STATE OF OREGON                    15
    possessory interest in a particular area solely for the purpose
    of mining,” the owner of a patented claim “gets a fee simple
    interest from the United States.” Clouser v. Espy, 
    42 F.3d 1522
    , 1525 n.2 (9th Cir. 1994). The mining claims at issue in
    this case are unpatented.
    By 1955, Congress had become increasingly aware of
    “abuses under the general mining laws by those persons who
    locate[d] mining claims on public lands for purposes other
    than that of legitimate mining activity.” H.R. Rep. No. 84-
    730, 1955 U.S.C.C.A.N. at 2478. Sham claims, for example,
    “could be used for selling timber from national forests, or
    obtaining free residential or agricultural land.” United States
    v. Shumway, 
    199 F.3d 1093
    , 1101 (9th Cir. 1999) (citing
    United States v. Curtis Nev. Mines, Inc., 
    611 F.2d 1277
    , 1282
    (9th Cir. 1980)). Congress was also concerned that according
    the holders of unpatented mining claims exclusive surface
    rights prevented the “efficient management and
    administration of the surface resources of the public lands.”
    H.R. Rep. No. 84-730, 1955 U.S.C.C.A.N. at 2474. Mining
    locations made under existing law, for example,
    frequently block[ed] access: to water needed
    in grazing use of the national forests or other
    public lands; to valuable recreational areas; to
    agents of the Federal Government desiring to
    reach adjacent lands for purposes of managing
    wild-game habitat or improving fishing
    streams so as to thwart the public harvest and
    proper management of fish and game
    resources on the public lands generally, both
    on the located lands and on adjacent lands.
    
    Id.
     at 2478–79.
    16            BOHMKER V. STATE OF OREGON
    To address these concerns, Congress adopted the Surface
    Resources and Multiple Use Act of 1955, Pub. L. No. 84-167,
    
    69 Stat. 367
     (1955). This law prohibits the location of any
    mining claim for purposes other than mining, see 
    30 U.S.C. § 612
    (a), and reserves in the United States – rather than
    granting to locators – the right to manage the surface
    resources of unpatented mining claims located after 1955,
    subject to the important proviso that “any use of the surface
    of any such mining claim by the United States, its permittees
    or licensees, shall be such as not to endanger or materially
    interfere with prospecting, mining or processing operations or
    uses reasonably incident thereto,” 
    id.
     § 612(b). The law
    states:
    Rights under any mining claim hereafter
    located under the mining laws of the United
    States shall be subject, prior to issuance of
    patent therefor, to the right of the United
    States to manage and dispose of the vegetative
    surface resources thereof and to manage other
    surface resources thereof (except mineral
    deposits subject to location under the mining
    laws of the United States). Any such mining
    claim shall also be subject, prior to issuance
    of patent therefor, to the right of the United
    States, its permittees, and licensees, to use so
    much of the surface thereof as may be
    necessary for such purposes or for access to
    adjacent land: Provided, however, That any
    use of the surface of any such mining claim by
    the United States, its permittees or licensees,
    shall be such as not to endanger or materially
    interfere with prospecting, mining or
    processing operations or uses reasonably
    BOHMKER V. STATE OF OREGON                   17
    incident thereto: Provided further, That if at
    any time the locator requires more timber for
    his mining operations than is available to him
    from the claim after disposition of timber
    therefrom by the United States, subsequent to
    the location of the claim, he shall be entitled,
    free of charge, to be supplied with timber for
    such requirements from the nearest timber
    administered by the disposing agency which
    is ready for harvesting under the rules and
    regulations of that agency and which is
    substantially equivalent in kind and quantity
    to the timber estimated by the disposing
    agency to have been disposed of from the
    claim: Provided further, That nothing in this
    subchapter and sections 601 and 603 of this
    title shall be construed as affecting or
    intended to affect or in any way interfere with
    or modify the laws of the States which lie
    wholly or in part westward of the ninety-

    control, appropriation, use, and distribution
    of ground or surface waters within any

    Id. § 612(b) (emphasis added). The legislation sought to
    “encourage mining activity on . . . public lands compatible
    with utilization, management, and conservation of surface
    resources such as water, soil, grass, timber, parks,
    monuments, recreation areas, fish, wildlife, and waterfowl.”

    18            BOHMKER V. STATE OF OREGON
    In 1970, Congress adopted the Mining and Minerals
    Policy Act of 1970, Pub. L. No. 91-631, 
    84 Stat. 1876
     (1970).
    This law declares it the policy of the United States to foster
    the development of an “economically sound and stable
    domestic mining” industry, but subject to “environmental
    needs,” 30 U.S.C. § 21a, making clear that “Congress did not,
    and does not, intend mining to be pursued at all costs,”
    Rinehart, 377 P.3d at 825. It states:
    The Congress declares that it is the continuing
    policy of the Federal Government in the
    national interest to foster and encourage
    private enterprise in (1) the development of
    economically sound and stable domestic
    mining, minerals, metal and mineral
    reclamation industries, (2) the orderly and
    economic development of domestic mineral
    resources, reserves, and reclamation of metals
    and minerals to help assure satisfaction of
    industrial, security and environmental needs,
    (3) mining, mineral, and metallurgical
    research, including the use and recycling of
    scrap to promote the wise and efficient use of
    our natural and reclaimable mineral resources,
    and (4) the study and development of methods
    for the disposal, control, and reclamation of
    mineral waste products, and the reclamation
    of mined land, so as to lessen any adverse
    impact of mineral extraction and processing
    upon the physical environment that may result
    from mining or mineral activities.

    2. Federal Laws Governing National Forests
    The Organic Administration Act, 
    30 Stat. 11
    , 35–36
    (1897), provides that nothing in 
    16 U.S.C. §§ 473
    –82 and 551
    “shall . . . prohibit any person from entering upon . . . national
    forests for all proper and lawful purposes, including that of
    prospecting, locating, and developing the mineral resources
    thereof.” 
    16 U.S.C. § 478
    . It also provides, however, that
    “[s]uch persons must comply with the rules and regulations
    covering such national forests.” 
    Id.
     The Organic Act,
    moreover, requires the Secretary of Agriculture to “make
    provisions for the protection against destruction by fire and
    depredations upon the public forests and national forests,”
    and it authorizes the Secretary to “make such rules and
    regulations” regarding “occupancy and use” as may be
    necessary “to preserve the forests thereon from destruction.”
    
    Id.
     § 551.
    Under this rulemaking authority, the U.S. Forest Service
    has promulgated rules regulating mining on national forest
    lands. These regulations require mining operators to comply
    with applicable federal and state air quality standards, water
    quality standards and standards for the disposal and treatment
    of solid wastes. See 
    36 C.F.R. § 228.8
    (a)–(c).
    4
    In 1977, Congress adopted the Surface Mining Control and
    Reclamation Act of 1977, Pub. L. No. 95-87, 
    91 Stat. 445
     (1977). In
    relevant part, this law allows the governor of a state to ask the Secretary
    of the Interior to designate lands as unsuitable for mining on the ground
    that “mining operations would have an adverse impact on lands used
    primarily for residential or related purposes.” 
    30 U.S.C. § 1281
    (a)–(b).
    The plaintiffs do not suggest this provision presented an option for Oregon
    here.
    20             BOHMKER V. STATE OF OREGON
    The Multiple-Use and Sustained-Yield Act of 1960, Pub.
    L. No. 86-517, 
    74 Stat. 215
     (1960), directs the Secretary of
    Agriculture “to develop and administer the renewable surface
    resources of the national forests for multiple use and
    sustained yield.” 
    16 U.S.C. § 529
    . After declaring it “the
    policy of the Congress that the national forests are established
    and shall be administered for outdoor recreation, range,
    timber, watershed, and wildlife and fish purposes,” the Act
    states that “[n]othing herein shall be construed as affecting
    the jurisdiction or responsibilities of the several States with
    respect to wildlife and fish on the national forests.” 
    Id.
     § 528.
    It further states that “[n]othing herein shall be construed so as
    to affect the use or administration of the mineral resources of
    national forest lands or to affect the use or administration of
    Federal lands not within national forests.” Id.
    The National Forest Management Act of 1976 (NFMA),
    Pub. L. No. 94-588, 
    90 Stat. 2949
     (1976), requires the
    Secretary of Agriculture to “develop . . . land and resource
    management plans for units of the National Forest System,
    coordinated with the land and resource management planning
    processes of State and local governments and other Federal
    agencies.” 
    16 U.S.C. § 1604
    (a). In developing such plans,
    the Secretary shall assure that they “provide for multiple use
    and sustained yield of the products and services obtained
    therefrom in accordance with the Multiple-Use Sustained-
    Yield Act of 1960.” 
    Id.
     § 1604(e)(1).
    In addition, federal lands, including those falling outside
    national forests, are governed by the Federal Land Policy and
    Management Act of 1976 (FLPMA), Pub. L. No. 94-579, 
    90 Stat. 2743
     (1976). FLPMA requires the Secretary of the
    Interior to develop land use plans for public lands, see
    
    43 U.S.C. § 1712
    (a), and to “manage the public lands under
    BOHMKER V. STATE OF OREGON                     21
    principles of multiple use and sustained yield,” 
    id.
     § 1732(a).
    FLPMA directs that, “[i]n managing the public lands the
    Secretary shall, by regulation or otherwise, take any action
    necessary to prevent unnecessary or undue degradation of the
    lands.” Id. § 1732(b). This “unnecessary or undue
    degradation” mandate applies not only to land use generally
    but also to the regulation of mining operations in particular.
    See id. (providing that nothing in FLPMA, other than the
    provision establishing the “unnecessary or undue
    degradation” standard, “shall in any way amend the Mining
    Law of 1872 or impair the rights of any locators or claims
    under that Act, including, but not limited to, rights of ingress
    and egress”). FLPMA further provides that “nothing in this
    Act shall be construed as . . . enlarging or diminishing the
    responsibility and authority of the States for management of
    fish and resident wildlife.” Id.
    Under FLPMA, the Bureau of Land Management (BLM)
    has issued regulations requiring mining operators to “comply
    with applicable Federal and state” air quality standards, water
    quality standards and standards for the disposal and treatment
    of solid wastes. 
    43 C.F.R. § 3809.420
    (b)(4)–(6). Another
    BLM regulation requires mining operators to comply with
    state environmental regulations that do not conflict with
    federal law: “If State laws or regulations conflict with this
    subpart regarding operations on public lands, you must follow
    the requirements of this subpart. However, there is no
    conflict if the State law or regulation requires a higher
    standard of protection for public lands than this subpart.” 
    Id.
    § 3809.3.

    3. Overview of Applicable Federal Laws
    The foregoing laws, in the aggregate, reflect Congress’
    intent to foster a productive mining industry but also its intent
    to protect the environment. These laws declare many federal
    lands “free and open” to exploration, 
    30 U.S.C. § 22
    ,
    preclude the United States from using the surface area of
    certain mining claims in a manner that would “endanger or
    materially interfere” with the underlying mining claims, 
    id.
    § 612(b), declare it to be the policy of the United States to
    foster “the development of economically sound and stable
    domestic mining . . . industries,” id. § 21a, and preserve a role
    for prospecting and mining in national forests, see 
    16 U.S.C. §§ 478
    , 528. At the same time, these laws require miners to
    comply with state laws, see 
    30 U.S.C. § 22
    , including state
    environmental laws, see, e.g., 
    36 C.F.R. § 228.8
    ; 
    43 C.F.R. §§ 3809.3
    , 3809.420(b), declare it the policy of the United
    States to assure that mining satisfies the nation’s
    “environmental needs,” 30 U.S.C. § 21a, require the
    Secretary of Agriculture to protect national forests from
    “depredations” and “destruction,” 
    16 U.S.C. § 551
    , require
    the Secretary of the Interior to protect public lands from
    “unnecessary or undue degradation,” 
    43 U.S.C. § 1732
    (b),
    and recognize the states’ broad authority to manage fish and
    wildlife, see 
    16 U.S.C. § 528
    ; 
    43 U.S.C. § 1732
    (b). In light
    of these provisions, it is common ground among the parties
    that the holders of unpatented mining claims do not have an
    “unfettered” right to explore and mine federal lands,
    unencumbered by federal and state environmental regulation.
    Nor does anyone argue that states’ environmental regulatory
    authority in this area is unbounded. Congress plainly
    intended to draw a line between these two extremes.
    BOHMKER V. STATE OF OREGON                     23
    4. The Granite Rock Decision
    The Supreme Court addressed this line drawing in
    California Coastal Commission v. Granite Rock Co.,
    
    480 U.S. 572
     (1987). After the Granite Rock Company
    secured unpatented mining claims on national forest land and
    the Forest Service approved the company’s plan of operations
    for the removal of limestone, the California Coastal
    Commission instructed the company to apply for a permit
    under the California Coastal Act, which prohibits any
    development, including mining, in the state’s coastal zone
    without a permit. See 
    id.
     at 575–76. The company sued to
    enjoin the enforcement of the permit requirement, arguing
    federal preemption. See 
    id. at 577
    .
    The Supreme Court rejected the company’s claims. The
    Court began by observing that
    [S]tate law can be pre-empted in either of two
    general ways. If Congress evidences an intent
    to occupy a given field, any state law falling
    within that field is pre-empted. If Congress
    has not entirely displaced state regulation over
    the matter in question, state law is still pre-
    empted to the extent it actually conflicts with
    federal law, that is, when it is impossible to
    comply with both state and federal law, or
    where the state law stands as an obstacle to
    the accomplishment of the full purposes and
    objectives of Congress.
    
    Id. at 581
     (alteration in original) (citations omitted) (quoting
    Silkwood v. Kerr-McGee Corp., 
    464 U.S. 238
    , 248 (1984)).
    24            BOHMKER V. STATE OF OREGON
    The Court next summarily rejected the proposition that
    the Mining Act of 1872 demonstrates an intent to preempt
    any state environmental regulation on federal lands. As the
    Court explained, “Granite Rock concedes that the Mining Act
    of 1872, as originally passed, expressed no legislative intent
    on the as yet rarely contemplated subject of environmental
    regulation.” Id. at 582.
    Next, the Court rejected Granite Rock’s argument that
    “the Federal Government’s environmental regulation of
    unpatented mining claims in national forests demonstrates an
    intent to pre-empt any state regulation.” Id. at 581–82. The
    Court concluded that
    the Forest Service regulations that Granite
    Rock alleges pre-empt any state permit
    requirement not only are devoid of any
    expression of intent to pre-empt state law, but
    rather appear to assume that those submitting
    plans of operations will comply with state
    laws. . . . It is impossible to divine from these
    regulations, which expressly contemplate
    coincident compliance with state law as well
    as with federal law, an intention to pre-empt
    all state regulation of unpatented mining
    claims in national forests.
    Id. at 583–84 (emphasis added) (citing 
    36 C.F.R. §§ 228.5
    (b),
    228.8(a)–(c), (h)). The Court added that “[n]either Granite
    Rock nor the United States contends that these Forest Service
    regulations are inconsistent with their authorizing statutes.”
    
    Id. at 584
    .
    BOHMKER V. STATE OF OREGON                     25
    The Court then turned to Granite Rock’s argument that
    “federal land management statutes demonstrate a legislative
    intent to limit States to a purely advisory role in federal land
    management decisions, and that the Coastal Commission
    permit requirement is therefore pre-empted as an
    impermissible state land use regulation.” 
    Id.
     The Court
    assumed arguendo that “the combination of the NFMA and
    the FLPMA pre-empts the extension of state land use plans
    onto unpatented mining claims in national forest lands.” 
    Id. at 585
    . But even under this assumption, the Court held that
    only “state land use plans” would be preempted, not state
    “environmental regulation.” 
    Id.
     at 585–86.
    The Court did not define the terms “land use planning”
    and “environmental regulation,” but it offered some guidance
    as to the distinction between the two:
    The line between environmental
    regulation and land use planning will not
    always be bright; for example, one may
    hypothesize a state environmental regulation
    so severe that a particular land use would
    become commercially impracticable.
    However, the core activity described by each
    phrase is undoubtedly different. Land use
    planning in essence chooses particular uses
    for the land; environmental regulation, at its
    core, does not mandate particular uses of the
    land but requires only that, however the land
    is used, damage to the environment is kept
    within prescribed limits. Congress has
    26             BOHMKER V. STATE OF OREGON
    indicated its understanding of land use
    planning and environmental regulation as
    distinct activities.
    
    Id. at 587
    .
    The Court suggested that a state’s decision to “prohibit”
    or “ban” mining would constitute land use planning, and
    hence would be preempted. See 
    id.
     at 586–87. It further
    intimated that a law would be preempted if, although couched
    as environmental regulation, its “true purpose” was to
    prohibit mining. 
    Id. at 588
    . At bottom, however, the Court
    made clear that “reasonable state environmental regulation is
    not pre-empted.” 
    Id. at 589
    ; see also 
    id. at 593
    .
    B. The Plaintiffs’ Arguments
    The plaintiffs argue: (1) Senate Bill 3 is field preempted
    because it constitutes state “land use planning” under Granite
    Rock; (2) Senate Bill 3 is conflict preempted because it is
    “prohibitory, not regulatory, in its fundamental character,”
    S.D. Mining Ass’n v. Lawrence County, 
    155 F.3d 1005
    , 1011
    (8th Cir. 1998); (3) Senate Bill 3 is conflict preempted
    because it does not constitute “reasonable state environmental
    regulation”; and (4) genuine issues of material fact preclude
    the entry of summary judgment in favor of the state. We
    address these arguments in turn.
    1. Field Preemption: The Plaintiffs’ Argument That
    Senate Bill 3 Constitutes State Land Use Planning
    Granite Rock assumed without deciding that “the
    combination of the NFMA and the FLPMA pre-empts the
    extension of state land use plans onto unpatented mining
    BOHMKER V. STATE OF OREGON                           27
    claims in national forest lands.” 
    480 U.S. at 585
    . We make
    the same assumption here.5 But like the Supreme Court in
    Granite Rock, we reject the plaintiffs’ preemption claim.
    Senate Bill 3 is an environmental regulation rather than a land
    use planning law. It does not choose or mandate land uses,
    has an express environmental purpose of protecting sensitive
    fish habitat, is not part of Oregon’s land use system and is
    carefully and reasonably tailored to achieve its environmental
    purpose without unduly interfering with mining operations.
    Senate Bill 3 is precisely the kind of reasonable state
    environmental regulation that the Supreme Court recognized
    in Granite Rock properly supplements rather than displaces
    federal land use planning decisions. To be sure, by restricting
    motorized suction dredge mining in rivers and streams
    designated as essential habitat for threatened salmonids,
    Senate Bill 3 will adversely impact the ability of some miners
    to extract gold deposits from their mining claims. But these
    impacts are the unavoidable consequences of a federal
    scheme that seeks to foster both the development of valuable
    mineral resources and proper stewardship and protection of
    the nation’s natural resources.
    The plaintiffs do not argue that Senate Bill 3 becomes a
    land use law under Granite Rock simply because it may
    render some of their mining claims commercially
    5
    We view the application of this assumption, as do the parties, as a
    question of field preemption rather than conflict preemption. But, even if
    we were to view it as a question of conflict preemption, we would find no
    conflict, because Senate Bill 3 is not a land use law.
    28               BOHMKER V. STATE OF OREGON
    impracticable.6 We agree with the United States that the
    preemption inquiry does not turn on profitability:
    To be sure, there will be miners (including
    some Plaintiffs) who cannot profitably extract
    certain minerals from their mining claims
    without the use of motorized equipment in the
    water. But . . . specific limitations on specific
    mining methods or activities have long been
    part of the business of mining. A State law
    cannot be deemed preempted solely on the
    basis that the cost of mining in compliance
    with the law makes a particular miner unable
    to profit from a particular mining claim.
    Brief of the United States as Amicus Curiae 26–27. Because
    “[v]irtually all forms of . . . regulation of mining claims – for
    instance, limiting the permissible methods of mining and
    prospecting in order to reduce incidental environmental
    damage – will result in increased operating costs,” Clouser,
    6
    The dissent contends the plaintiffs have made a commercial
    impracticability argument. Dissent 68. We have, however, carefully
    reviewed their opening and reply briefs on appeal, and no such argument
    exists there. The plaintiffs argue Senate Bill 3 is preempted because it
    prohibits mining, not because it renders their claims unprofitable. As the
    plaintiffs make clear, “[t]his appeal is not about profitability, but about
    prohibition.” Reply Br. 41. The plaintiffs have therefore waived the
    argument. See Indep. Towers of Wash. v. Washington, 
    350 F.3d 925
    , 929
    (9th Cir. 2003) (“[W]e will not consider any claims that were not actually
    argued in appellant’s opening brief.”); Smith v. Marsh, 
    194 F.3d 1045
    ,
    1052 (9th Cir. 1999) (“[A]rguments not raised by a party in its opening
    brief are deemed waived.”); Greenwood v. Fed. Aviation Admin., 
    28 F.3d 971
    , 977 (9th Cir. 1994) (“We will not manufacture arguments for an
    appellant . . . .”). This rule applies with particular force where, as here,
    the plaintiffs have expressly disclaimed the argument in question.
    BOHMKER V. STATE OF OREGON                     29
    
    42 F.3d at 1530
    , virtually every environmental regulation will
    render at least some mining claims commercially
    impracticable, and virtually every environmental regulation
    would therefore be preempted under a commercial
    impracticability test, a proposition that is impossible to
    reconcile with Granite Rock’s central holding that
    “reasonable state environmental regulation is not pre-
    empted,” Granite Rock, 
    480 U.S. at 589
     (emphasis added).
    A commercial impracticability theory, moreover, would
    require the preemption analysis to turn on each miner’s
    individual financial circumstances: the law would be
    preempted as to some miners but not as to others. Indeed, a
    commercial impracticability test would give the greatest
    protection to the least profitable mining operations, and it
    would handcuff regulators from restricting even the most
    environmentally destructive mining methods. So long as a
    particularly destructive method of mining – such as blasting
    – presented the only commercially practicable means of
    extracting minerals, regulators would be barred from
    restricting that practice. We do not read Granite Rock as
    supporting that result. As the California Supreme Court has
    explained, federal law does not show that Congress “viewed
    mining as the highest and best use of federal land wherever
    minerals were found.” Rinehart, 377 P.3d at 830.
    Rather, the plaintiffs contend that Senate Bill 3 constitutes
    a state land use planning law because it “prohibits” a
    particular “use” of the land (motorized mining methods) in
    particular “zones” (rivers and streams designated as essential
    salmonid habitat). The plaintiffs base this argument on
    language in Granite Rock explaining that
    the core activity described by [environmental
    regulation and land use planning] is
    30               BOHMKER V. STATE OF OREGON
    undoubtedly different. Land use planning in
    essence chooses particular uses for the land;
    environmental regulation, at its core, does not
    mandate particular uses of the land but
    requires only that, however the land is used,
    damage to the environment is kept within
    prescribed limits.
    
    480 U.S. at 587
    . The plaintiffs argue Senate Bill 3 is state
    land use planning under this language because (1) it chooses
    particular uses of the land and (2) does not prescribe limits on
    environmental damage by, for example, promulgating a
    pollution standard.
    We disagree. First, Senate Bill 3 does not “choose[]” or
    “mandate particular uses of the land.” 
    Id.
     It simply restricts
    one method of mining.7
    7
    Like the permit requirement in Granite Rock, moreover, Senate
    Bill 3 is not a “ban” or “prohibition” on mining. See 
    480 U.S. at
    586–87.
    Senate Bill 3 does not prohibit the plaintiffs’ mining operations. Many of
    the plaintiffs engage in upland mining, mine in rivers and streams that are
    not designated as essential habitat or use non-motorized mining methods
    such as gold panning. Plaintiff Larry Coon, for example, did not testify
    that all of his mining claims are located in essential salmon habitat, and he
    contends only that the legislation will significantly limit his mining
    operations, not eliminate them. Coon decl. ¶¶ 2, 5. Only half of plaintiff
    Millennium Diggers’ mining claims are located within essential salmon
    habitat. Darnell decl. ¶ 4. Some of its members, moreover, “utilize non-
    motorized techniques, such as gold panning.” Id. ¶ 3. Plaintiff Jason
    Gill’s mining operations occur between 50 and 300 feet from a creek. Gill
    decl. ¶¶ 3–4. These operations would not be affected by Senate Bill 3,
    which applies solely to in-stream mining. The deposits associated with
    plaintiff Joel Grothe’s claim fall not only within the creek bottom but also
    within 100 yards of the creek. Grothe decl. ¶ 7. Only some of plaintiff
    Willamette Valley Miners’ mining claims are located in essential salmon
    habitat. Hunter decl. ¶ 9. Its members’ mining, moreover, includes “non-
    BOHMKER V. STATE OF OREGON                             31
    Second, Senate Bill 3 does not constitute land use
    planning simply because it prohibits a particular mining
    method rather than “prescrib[ing] limits” on environmental
    damage by adopting a pollution standard. Granite Rock does
    not hold that only standards, not restrictions on activities, are
    permissible environmental regulation. On the contrary,
    Granite Rock says only that “environmental regulation, at its
    core, does not mandate particular uses of the land but requires
    only that, however the land is used, damage to the
    environment is kept within prescribed limits.” 
    480 U.S. at 587
     (emphasis added).8 It does not purport to define the
    entire universe of environmental regulation as consisting
    solely of limit-prescribing standards. That formalistic
    approach ignores the practical reality that environmental
    regulation may take several forms, and it would make no
    sense, given that regulations imposing pollution standards can
    motorized techniques, such as gold panning.” Id. ¶ 8. Plaintiff Michael
    Lovett testified that Senate Bill 3 would significantly limit his mining
    operations, but not that it would eliminate them. Lovett decl. ¶ 4. We
    take seriously the plaintiffs’ contentions that Senate Bill 3 will seriously
    impact their mining operations with respect to at least some of their
    mining claims. But the plaintiffs’ own declarations make clear that Senate
    Bill 3 is not a ban on mining.

    The dissenting opinion characterizes us as treating this language as
    “non-binding dicta (Dissent 58 n.2),” but that is not the case. In addition,
    the dissent’s theory that a distinction between regulations dictating “uses”
    and regulations dictating “standards” would provide a “clear line between
    land use planning and environmental regulation” (Dissent 58) eludes us.
    Would a regulation limiting the size of suction dredge hoses prohibit a
    “use” (of larger hoses) or prescribe a “standard” (on the size of the hose
    and, consequently, the volume of material to be dredged)? Would a
    regulation limiting the size of the vehicles miners could use to reach their
    claims prohibit a “use” (of heavy vehicles) or prescribe a “standard” (on
    the weight of vehicles and the resulting damage to the surface of the
    forest)?
    32                BOHMKER V. STATE OF OREGON
    impact mining operations every bit or even more than
    regulations restricting particular mining methods. The
    plaintiffs concede, for example, that “Oregon’s water quality
    standard for turbidity” constitutes a permissible, non-
    preempted “environmental regulation” under Granite Rock.
    A stringent turbidity standard, however, might have a greater
    adverse impact on the plaintiffs’ mining operations than
    Senate Bill 3’s targeted restrictions on motorized mining.
    Senate Bill 3 also is not part of Oregon’s extensive and
    distinct land use system.         That system requires the
    development of comprehensive plans by local governments,
    implemented through zoning, and reviewed by the Oregon
    Land Conservation and Development Commission. Those
    decisions, in turn, are reviewed by a State Land Use Board of
    Appeals, which has developed significant land use case law.
    See generally 
    Or. Rev. Stat. §§ 197.005
    –197.860,
    215.010–215.990. Senate Bill 3 stands apart from that
    regime.
    The plaintiffs’ argument, moreover, overlooks Senate
    Bill 3’s obvious and important environmental purpose.9 The
    Oregon legislature adopted Senate Bill 3’s restrictions on
    motorized mining “[i]n order to protect indigenous
    anadromous salmonids and habitat essential to the recovery
    9
    Although the plaintiffs contend Oregon’s purpose in adopting Senate
    Bill 3 is irrelevant to the preemption analysis, our case law is to the
    contrary. See Puente Ariz. v. Arpaio, 
    821 F.3d 1098
    , 1106 n.8 (9th Cir.
    2016) (rejecting the proposition “that the state’s purpose in passing a
    statute is not relevant to our preemption analysis, as both this court and the
    Supreme Court have analyzed purpose in preemption cases”). In Granite
    Rock, moreover, the Supreme Court expressly considered whether the
    state’s “true purpose in enforcing a permit requirement [was] to prohibit
    [the plaintiff’s] mining entirely.” Granite Rock, 
    480 U.S. at 588
    .
    BOHMKER V. STATE OF OREGON                    33
    and conservation of Pacific lamprey.” 2017 Or. Laws ch.
    300, § 4(2). “‘Essential indigenous anadromous salmonid
    habitat’ means the habitat that is necessary to prevent the
    depletion of indigenous anadromous salmonid species during
    their life history stages of spawning and rearing.” 
    Or. Rev. Stat. § 196.810
    (1)(g)(B).         “‘Indigenous anadromous
    salmonid’ means chum, sockeye, Chinook and Coho salmon,
    and steelhead and cutthroat trout, that are members of the
    family Salmonidae and are listed as sensitive, threatened or
    endangered by a state or federal authority.”             
    Id.
    § 196.810(1)(g)(C).
    Similarly, in Senate Bill 838, the legislature found that
    “[m]ining that uses motorized equipment in the beds and
    banks of the rivers of Oregon can pose significant risks to
    Oregon’s natural resources, including fish and other wildlife,
    riparian areas, water quality, the investments of this state in
    habitat enhancement and areas of cultural significance to
    Indian tribes.” 2013 Or. Laws ch. 783, § 1(4). The
    legislature found that, “[b]etween 2007 and 2013, mining that
    uses motorized equipment in the beds and banks of the rivers
    of Oregon increased significantly, raising concerns about the
    cumulative environmental impacts.” Id. § 1(5). It found that
    “[t]he regulatory system related to mining that uses motorized
    equipment in the beds and banks of the rivers of Oregon
    should be efficient and structured to best protect
    environmental values.” Id. § 1(6).
    The plaintiffs’ attempts to cast doubt on Senate Bill 3’s
    environmental purpose are unconvincing. They contend that
    Senate Bill 3’s restrictions were not “required to advance any
    bona fide environmental interest of the State of Oregon” and
    instead were “primarily motivated by objections from other
    34            BOHMKER V. STATE OF OREGON
    users of the waterways.” Their evidence, however, fails to
    substantiate these broad claims.
    They rely, first, on two Oregon statutes, but neither one
    undermines the Oregon legislature’s determination that
    restrictions on motorized mining are necessary to protect fish
    habitat. The first of these statutes, former 
    Or. Rev. Stat. § 517.123
    (3), adopted in 1999, simply found that
    “prospecting, small scale mining and recreational mining . . .
    [c]an be conducted in a manner that is not harmful and may
    be beneficial to fish habitat and fish propagation.” 1999 Or.
    Laws ch. 354, § 2(3). There is, of course, no inconsistency
    between the general finding that small scale mining can be
    conducted in a non-harmful manner and Senate Bill 3’s
    conclusion that it was necessary, “[i]n order to protect
    indigenous anadromous salmonids and habitat essential to the
    recovery and conservation of Pacific lamprey,” to restrict one
    particular type of small scale mining – “motorized in-stream
    placer mining” – in certain environmentally sensitive areas.
    2017 Or. Laws ch. 300, § 4(2). In any event, the Oregon
    legislature repealed the 1999 finding in 2013, noting a
    “significant[]” increase in motorized mining between 2007
    and 2013 that “pose[d] significant risks to Oregon’s natural
    resources, including fish and other wildlife.” 2013 Or. Laws
    ch. 783, §§ 1(4)–(5), 10. The 1999 finding, therefore, does
    nothing to undermine Senate Bill 3’s avowed and self-evident
    environmental purpose.
    The second statute upon which the plaintiffs rely, 
    Or. Rev. Stat. § 517.005
    , says only that
    Technological advances in the mining
    industry, coupled with reclamation efforts,
    have greatly reduced the environmental
    BOHMKER V. STATE OF OREGON                    35
    impacts of mining operations. The size and
    scope of modern operations is such that the
    operations do not cause interference with
    other natural resource uses, particularly in an
    area as vast as eastern Oregon.
    
    Or. Rev. Stat. § 517.005
    (4). Because this provision pertains
    to mining generally, and not to the particular environmental
    concerns addressed by Senate Bill 3, it too does nothing
    to undermine the validity of Senate Bill 3’s stated
    environmental purpose.
    Beyond these two statutes, the plaintiffs’ evidence
    regarding Senate Bill 3’s purpose consists solely of a single
    statement in the record by plaintiff Michael Hunter. Hunter
    testified that, “[i]n [the Willamette Valley Miners’]
    experience, the State of Oregon regulates in utter disregard to
    the National interest in mineral development, instead seeking
    to placate other user groups who resent, and desire to
    eliminate the presence of miners on public lands.” Hunter
    decl. ¶ 12. Even granting this statement may reflect Hunter’s
    sincere personal opinion, it is wholly lacking in the specific
    factual support that would be needed to create a genuine issue
    of material fact as to Senate Bill 3’s purpose. See FTC v.
    Publ’g Clearing House, Inc., 
    104 F.3d 1168
    , 1171 (9th Cir.
    1997) (as amended) (“A conclusory, self-serving affidavit,
    lacking detailed facts and any supporting evidence, is
    insufficient to create a genuine issue of material fact.”).
    In sum, because Senate Bill 3 has a clear environmental
    purpose, is tailored to that purpose, and does not prohibit
    mining, choose land uses or fall within Oregon’s distinct land
    use planning system, we hold that it is an environmental
    regulation rather than a state land use planning law. Thus,
    36            BOHMKER V. STATE OF OREGON
    even assuming for purposes of our analysis that federal law
    preempts the extension of state land use plans on federal
    lands, Senate Bill 3 is not preempted.
    Our dissenting colleague takes the view that any state
    environmental regulation – whether in the form of a “use”
    restriction or a “standard” – constitutes a “de facto land use
    regulation preempted by federal law” whenever it renders
    regulated mining claims commercially impracticable. Dissent
    70–71. Where a conflict exists between regulated mining
    claims and a need to protect the environment, the mining
    claims must always take precedence.
    The dissent assures us that a commercial practicability
    test would not undermine environmental protection because
    it would affect only state regulation, not federal regulation.
    Dissent 69 (“Even if federal law preempts Oregon’s attempt
    to apply Senate Bill 3 to federal lands, the miners must still
    comply with all environmental laws and standards imposed
    expressly by federal statutes and regulations.”). But this is
    not how environmental protection on federal lands is
    achieved. As Granite Rock recognizes, the federal scheme
    relies on the states to provide environmental regulation of
    mining claims on federal lands. Because federal law
    “expressly contemplate[s] coincident compliance with state
    as well as with federal law,” Granite Rock, 
    480 U.S. at 584
    ,
    “reasonable state environmental regulation is not pre-
    empted,” 
    id. at 589
    . That is why the U.S. Departments of
    Agriculture and the Interior, which are the federal agencies
    charged with management and environmental protection of
    the federal lands impacted by Senate Bill 3, have joined this
    case on the side of Oregon, urging us to uphold Senate Bill 3
    against the plaintiffs’ preemption challenge.
    BOHMKER V. STATE OF OREGON                    37
    Under the dissent’s commercial impracticability test, even
    a patently destructive method of mining would be permitted
    as long as it represented the only commercially viable means
    of extracting minerals from the ground, irrespective of the
    havoc it would wreak on wildlife and habitat. This is the
    mining “at all costs” approach that the plaintiffs expressly
    disclaim. Reply Br. 29. We can find no support for that
    approach in federal mining law or case law. On the contrary,
    federal mining law, see, e.g., 30 U.S.C. § 21a, the Supreme
    Court and the United States as amicus curiae all agree that
    mining must be pursued consistent with environmental needs,
    not irrespective of environmental cost. That is why
    “reasonable state environmental regulation is not pre-
    empted.” Granite Rock, 
    480 U.S. at 589
    . We respectfully
    decline the dissent’s suggestion to hold that reasonable state
    environmental regulation is preempted merely because it
    renders regulated mining claims unprofitable. That approach
    cannot be reconciled with the balance Congress has sought to
    achieve.
    2. Conflict Preemption: The Plaintiffs’ Argument That
    Senate Bill 3 Is Preempted Because It Is
    “Prohibitory” Rather Than “Regulatory”
    We next consider the plaintiffs’ contention that Senate
    Bill 3 is conflict preempted because it is “prohibitory” rather
    than “regulatory” in its fundamental character. There is, of
    course, some overlap between this argument and the field
    preemption argument we have just addressed. In both
    instances, the plaintiffs contend Senate Bill 3 is preempted
    because it prohibits a particular mining method rather than
    merely subjecting that mining method to an environmental
    standard. Despite these similarities, however, we treat the
    two arguments as distinct. The plaintiffs’ field preemption
    38            BOHMKER V. STATE OF OREGON
    argument is based on Granite Rock’s distinction between land
    use planning on the one hand and environmental regulation
    on the other. By contrast, their current argument – finding a
    distinction between “prohibitory” and “regulatory” state
    environmental regulation and deeming the former conflict
    preempted – is largely based on South Dakota Mining
    Association v. Lawrence County, 
    155 F.3d 1005
     (8th Cir.
    1998).
    In South Dakota Mining, county voters approved an
    ordinance that amended the county’s zoning laws to prohibit
    the issuance of new or amended permits for surface metal
    mining in the 40,000-acre Spearfish Canyon Area, 90 percent
    of which fell within a national forest. See 
    id.
     at 1006–07.
    The plaintiffs argued the ordinance was preempted because
    it stood as an obstacle to the accomplishment of the full
    purposes and objectives of Congress embodied in the Mining
    Act of 1872. See 
    id. at 1009
    .
    “To determine the purposes and objectives that are
    embodied in the Mining Act,” the Eighth Circuit considered
    the language of the Mining and Minerals Policy Act of 1970,
    30 U.S.C. § 21a, and the Mining Act itself, 
    30 U.S.C. § 22
    .
    As noted, § 21a states:
    The Congress declares that it is the continuing
    policy of the Federal Government in the
    national interest to foster and encourage
    private enterprise in (1) the development of
    economically sound and stable domestic
    mining, minerals, metal and mineral
    reclamation industries, (2) the orderly and
    economic development of domestic mineral
    resources, reserves, and reclamation of metals
    BOHMKER V. STATE OF OREGON                   39
    and minerals to help assure satisfaction of
    industrial, security and environmental needs,
    (3) mining, mineral, and metallurgical
    research, including the use and recycling of
    scrap to promote the wise and efficient use of
    our natural and reclaimable mineral resources,
    and (4) the study and development of methods
    for the disposal, control, and reclamation of
    mineral waste products, and the reclamation
    of mined land, so as to lessen any adverse
    impact of mineral extraction and processing
    upon the physical environment that may result
    from mining or mineral activities.
    30 U.S.C. § 21a. The Mining Act, in turn, states:
    Except as otherwise provided, all valuable
    mineral deposits in lands belonging to the
    United States, both surveyed and unsurveyed,
    shall be free and open to exploration and
    purchase, and the lands in which they are
    found to occupation and purchase, by citizens
    of the United States and those who have
    declared their intention to become such, under
    regulations prescribed by law, and according
    to the local customs or rules of miners in the
    several mining districts, so far as the same are
    applicable and not inconsistent with the laws
    of the United States.
    Id. § 22. In light of these statutes, the Eighth Circuit
    concluded the Mining Act embodies several congressional
    purposes, including
    40            BOHMKER V. STATE OF OREGON
    the encouragement of exploration for and
    mining of valuable minerals located on
    federal lands, providing federal regulation of
    mining to protect the physical environment
    while allowing the efficient and economical
    extraction and use of minerals, and allowing
    state and local regulation of mining so long as
    such regulation is consistent with federal
    mining law.
    South Dakota Mining, 
    155 F.3d at 1010
    .
    The Eighth Circuit next considered whether the
    challenged ordinance stood as an obstacle to these purposes
    and objectives. At the outset, the court observed that,
    because surface metal mining was the only practical way to
    “actually mine the valuable mineral deposits located on
    federal land in the area,” the ordinance was “a de facto ban on
    mining in the area.” 
    Id. at 1011
    . The court then held that, as
    a de facto ban on mining, the ordinance was preempted:
    The ordinance’s de facto ban on mining
    on federal land acts as a clear obstacle to the
    accomplishment of the Congressional
    purposes and objectives embodied in the
    Mining Act. Congress has encouraged
    exploration and mining of valuable mineral
    deposits located on federal land and has
    granted certain rights to those who discover
    such minerals. Federal law also encourages
    the economical extraction and use of these
    minerals. The Lawrence County ordinance
    completely frustrates the accomplishment of
    these federally encouraged activities. A local
    BOHMKER V. STATE OF OREGON                   41
    government cannot prohibit a lawful use of
    the sovereign’s land that the superior
    sovereign itself permits and encourages. To
    do so offends both the Property Clause and
    the Supremacy Clause of the federal
    Constitution. The ordinance is prohibitory,
    not regulatory, in its fundamental character.
    The district court correctly ruled that the
    ordinance was preempted.
    
    Id.
     (emphasis added).
    The plaintiffs discern from South Dakota Mining, and
    from federal statutes governing mining, a general principle
    that state environmental regulations are preempted,
    categorically, whenever they are “prohibitory” rather than
    “regulatory” in their “fundamental character.” “Even
    prohibitions on the use of particular mining methods,” they
    say, “create an obstacle to the full accomplishment of
    Congressional purposes.” We disagree.
    Like the United States, “[w]e would agree that were a
    state to completely prohibit all mining activity on federal
    lands, federal mining law would preempt the ban.” Brief of
    the United States as Amicus Curiae 21. We cannot agree
    with the plaintiffs, however, that conflict preemption in this
    area turns on whether a state environmental regulation could
    be viewed as “prohibitory” or “regulatory” in its
    “fundamental character.” For one thing, as the government
    explains, the distinction likely would be unworkable:
    It is unclear how this Court would determine
    whether [Senate Bill 3] is “prohibitory . . . in
    its fundamental character.” South Dakota
    42               BOHMKER V. STATE OF OREGON
    Mining, 
    155 F.3d at 1005
    . Certainly it
    prohibits some very specific types of mining
    activity in very specific places . . . , but in the
    process of identifying where its prohibitions
    apply it seems “regulatory” in nature. In a
    sense, [Senate Bill 3] is both regulatory and
    prohibitory, but whether that makes it
    preempted is a question to be answered by
    long-established preemption law. Regardless
    of whether a state regulatory prohibition is
    considered “prohibitory” or “regulatory,” it is
    permissible so long as it does not pose an
    obstacle to Congressional purposes or make
    compliance with federal law physically
    impossible.
    Id. at 22.10
    We are not persuaded, moreover, that federal statutes
    governing mining evince a congressional purpose to preempt,
    categorically, state environmental regulations that are
    “prohibitory” in their “fundamental character.”11 The Mining
    Act of 1872, upon which the plaintiffs heavily rely, states
    10
    We have drawn a distinction between “regulatory” and
    “prohibitory” laws in other contexts, but those analyses are not helpful
    here. E.g., United States v. Dotson, 
    615 F.3d 1162
    , 1168 (9th Cir. 2010)
    (Assimilative Crimes Act).
    11
    This conclusion is a consistent with a leading treatise on mining
    law. See 5 American Law of Mining § 174.04[2][c] (2d ed. 2018) (noting
    that “state law requirements prohibiting a federally authorized activity on
    federal land are less likely to be upheld,” but “the Granite Rock decision
    indicates that state law requirements that can be harmonized with federal
    regulations may be enforceable”).
    BOHMKER V. STATE OF OREGON                              43
    only that “all valuable mineral deposits in lands belonging to
    the United States. . . shall be free and open to exploration and
    purchase.” 
    30 U.S.C. § 22
    . The plaintiffs contend that this
    statute’s “free and open” language “create[s] a Congressional
    mining objective inconsistent with state-law based
    prohibitions of mining activity.” But the Mining Act
    expressly incorporates state regulation of mining activity,
    stating that exploration authorized by the statute must occur
    “under regulations prescribed by law.” Id.12 Nothing in the
    12
    Although the phrase “under regulations prescribed by law” applies
    to state as well as federal law – a conclusion that follows from § 22’s later
    reference to “laws of the United States,” see Corley v. United States,
    
    556 U.S. 303
    , 315 (2009) – the plaintiffs suggest it incorporates only state
    property law, not state environmental law, pointing out that a separate
    provision of the Mining Act incorporates state law only with respect to
    possessory title. See 
    30 U.S.C. § 26
     (granting rights of possession and
    enjoyment to locators who “comply with the laws of the United States,
    and with State, territorial, and local regulations not in conflict with the
    laws of the United States governing their possessory title” (emphasis
    added)). But there is nothing surprising in the fact that § 26, a provision
    addressing possessory title, refers only to state laws respecting title. This
    tells us nothing about the scope of the state law incorporated by § 22,
    which deals with the much broader subject of making federal lands free
    and open to exploration. Indeed, that § 26 expressly limits the
    incorporation of state law to laws respecting “possessory title,” and § 22
    does not, supports the conclusion that the scope of state laws incorporated
    by § 22 is not limited to those respecting title. See Russello v. United
    States, 
    464 U.S. 16
    , 23 (1983) (“[W]here Congress includes particular
    language in one section of a statute but omits it in another section of the
    same Act, it is generally presumed that Congress acts intentionally and
    purposely in the disparate inclusion or exclusion.” (alteration in original)
    (quoting United States v. Wong Kim Bo, 
    472 F.2d 720
    , 722 (5th Cir.
    1972))); see also Rinehart, 377 P.3d at 824 (explaining that § 22’s
    “express acknowledgement[] of the application of state and local law to
    federal mining claims suggest[s] an apparent willingness on the part of
    Congress to let federal and state regulation broadly coexist”).
    44               BOHMKER V. STATE OF OREGON
    Mining Act suggests a categorical distinction between
    “prohibitory” and “regulatory” state laws.
    We likewise find no support for the plaintiffs’ position in
    the Surface Resources and Multiple Use Act of 1955. This
    law gives the United States the right to manage surface
    resources on unpatented mining claims, subject to the
    important proviso that “any use of the surface of any such
    mining claim by the United States, its permittees or licensees,
    shall be such as not to endanger or materially interfere with
    prospecting, mining or processing operations or uses
    reasonably incident thereto.” 
    30 U.S.C. § 612
    (b) (emphasis
    added). As with the Mining Act of 1872, nothing in this law
    suggests Congress intended to draw a distinction between
    “prohibitory” and “regulatory” measures.           We have,
    moreover, already held that this law permits environmental
    regulations, such as Senate Bill 3, that prohibit the use of
    particular mining methods. See United States v. Richardson,
    
    599 F.2d 290
    , 291, 295 (9th Cir. 1979) (holding the Forest
    Service could, without running afoul of § 612(b), require the
    locators of unpatented mining claims on national forest lands
    to use nondestructive methods of prospecting, where the
    The plaintiffs’ reliance on 
    30 U.S.C. § 28
     is similarly unpersuasive.
    That provision requires locators to perform annual work on their
    unpatented claims to maintain their exclusive rights. See 
    30 U.S.C. § 28
    .
    Nothing in Senate Bill 3 precludes miners from performing work on or
    making improvements to their claims, and to the extent miners elect not
    to perform work because state environmental regulation makes working
    or improving their claims unprofitable, that scenario is as likely to arise
    from a “regulatory” measure as it is from a “prohibitory” one.
    BOHMKER V. STATE OF OREGON                           45
    locators’ utilization of blasting and bulldozing was
    destructive to the surface resources).13
    The plaintiffs’ argument similarly finds no support in the
    Mining and Minerals Policy Act of 1970. Under this law:
    The Congress declares that it is the continuing
    policy of the Federal Government in the
    national interest to foster and encourage
    private enterprise in (1) the development of
    economically sound and stable domestic
    mining, minerals, metal and mineral
    reclamation industries, (2) the orderly and
    economic development of domestic mineral
    resources, reserves, and reclamation of metals
    and minerals to help assure satisfaction of
    industrial, security and environmental needs,
    (3) mining, mineral, and metallurgical
    research, including the use and recycling of
    scrap to promote the wise and efficient use of
    our natural and reclaimable mineral resources,
    13
    We also find nothing in the 1955 law to suggest Congress intended
    to limit state environmental regulation. On its face, § 612(b) imposes
    limits on only the federal government, not states, and it expressly
    preserves state water quality controls:
    [N]othing in this subchapter . . . shall be construed as
    affecting or intended to affect or in any way interfere
    with or modify the laws of the States which lie wholly
    or in part westward of the ninety-eighth meridian
    relating to the ownership, control, appropriation, use,
    and distribution of ground or surface waters within any
    unpatented mining claim.
    
    30 U.S.C. § 612
    (b).
    46            BOHMKER V. STATE OF OREGON
    and (4) the study and development of methods
    for the disposal, control, and reclamation of
    mineral waste products, and the reclamation
    of mined land, so as to lessen any adverse
    impact of mineral extraction and processing
    upon the physical environment that may result
    from mining or mineral activities.
    30 U.S.C. § 21a (emphasis added).
    The plaintiffs read this statutory language to suggest that
    Congress intended to meet the nation’s environmental needs
    solely through the process of reclamation, not through
    regulation of mining itself. This reading, however, lacks any
    basis in the statutory text or in case law. The plaintiffs
    alternatively look to the statute’s reference to “lessen[ing]”
    adverse environmental impacts. They contend “[l]essening
    impact is a regulatory action,” distinct from prohibiting
    mining activities. We again disagree. The statute’s reference
    to lessening impacts relates solely to reclamation. In any
    event, regulators can lessen impacts through either
    “prohibitory” or “regulatory” action. E.g., Richardson,
    
    599 F.2d at 295
    .
    The plaintiffs’ reliance on the Surface Mining Control and
    Reclamation Act of 1977 is equally flawed. This law allows
    a state to ask the Secretary of the Interior to declare
    residential areas unsuitable for mining. See 
    30 U.S.C. § 1281
    . The plaintiffs contend that “Congress’ provision of
    this and other federal processes for resolving state/federal
    conflict over mining on federal land is utterly inconsistent
    with any Congressional intent to allow states to simply
    prohibit the mining themselves.” We agree, of course, that
    states cannot simply prohibit mining on federal lands. But
    BOHMKER V. STATE OF OREGON                             47
    nothing in § 1281 suggests Congress intended to preempt
    environmental regulations prohibiting particular mining
    methods in specified, environmentally sensitive areas.
    The plaintiffs’ reliance on federal land management
    statutes suffers from similar problems. The Supreme Court
    has examined these statutes and concluded that Congress did
    not intend by these laws to preempt reasonable state
    environmental regulation. See Granite Rock, 
    480 U.S. at
    582–93. Nothing in these statutes, moreover, suggests a
    distinction between “prohibitory” and “regulatory” state
    environmental regulation.
    In sum, the plaintiffs’ proposed distinction between
    regulations that are “prohibitory” or “regulatory” in their
    “fundamental character” is neither workable nor grounded in
    the federal statutes upon which the plaintiffs rely. We find in
    these statutes no indication that Congress intended to preempt
    state environmental regulation merely because it might be
    viewed as “prohibitory.” We therefore reject the plaintiffs’
    contention that Senate Bill 3 stands as an obstacle to the
    accomplishment of the full purposes and objectives of
    Congress merely because it “prohibits” a particular method of
    mining in the portions of rivers and streams containing
    essential habitat for threatened and endangered salmonids.14
    14
    This conclusion is consistent with the California Supreme Court’s
    recent decision in Rinehart, 
    377 P.3d 818
    , cert. denied sub nom. Rinehart
    v. California, 
    138 S. Ct. 635
     (2018). In rejecting a conflict preemption
    challenge to a California law prohibiting suction dredge mining in order
    to protect endangered coho salmon habitats, Rinehart concluded that
    “[t]he federal statutory scheme does not prevent states from restricting the
    use of particular mining techniques based on their assessment of the
    collateral consequences for other resources.” 
    Id. at 829
    .
    48              BOHMKER V. STATE OF OREGON
    This conclusion does not place us at odds with South
    Dakota Mining. Although the Eighth Circuit drew a
    distinction between “prohibitory” and “regulatory” measures,
    it did so in the context of a county ordinance amounting to a
    “de facto ban on mining” that applied broadly and
    indiscriminately to federal lands within the county. 
    155 F.3d at 1011
    . The ordinance at issue effectively prohibited
    mining, covered 40,000 acres, targeted federal lands
    (90 percent of the land affected by the ban was in a national
    forest), lacked any environmental purpose and was part of the
    county’s zoning law. Senate Bill 3, by contrast, is not part of
    Oregon’s zoning law, is not a de facto ban on mining, has an
    express environmental purpose, does not single out federal
    land and carefully targets only designated essential salmonid
    habitat. Whereas the ordinance in South Dakota Mining was
    an attempt by county voters to overrule federal land use
    decisions, Senate Bill 3 complements those decisions by
    playing the traditional role served by state environmental
    regulation. See, e.g., 
    36 C.F.R. § 228.8
    (a)–(c); 
    43 C.F.R. §§ 3809.3
    , 3809.420(b)(4)–(6). Were Senate Bill 3 an
    encroachment on federal land use decisions, we would expect
    the United States to say so. The United States, however,
    takes the position that Senate Bill 3 “is not preempted by
    federal law.” Brief of the United States as Amicus Curiae

    Elliott v. Oregon International Mining Co., 
    654 P.2d 663
     (Or.
    Ct. App. 1982), does not require a different conclusion. Each
    case predates the Supreme Court’s holding in Granite Rock
    that reasonable state environmental regulation is not
    preempted by federal law. See Granite Rock, 
    480 U.S. at 589
    ; Rinehart, 377 P.3d at 829. Similar to South Dakota
    Mining, moreover, most of these cases involved improper
    attempts by local governments to displace, rather than
    supplement, federal land use decisions. See Ventura County,
    
    601 F.2d at
    1084–85 (precluding the county from applying
    “land use planning controls” “in an attempt to substitute its
    judgment for that of Congress”); Brubaker, 652 P.2d at 1059
    (“This is not denial of a permit because of failure to comply
    with reasonable regulations supplementing the federal mining
    laws, but reflects simply a policy judgment as to the
    appropriate use of the land.”); Elliott, 
    654 P.2d at 665, 668
    (barring the application of county zoning laws prohibiting
    mining because they did “not simply supplement federal
    mining law”). In addition, Ventura County involved the
    Mineral Lands Leasing Act of 1920, not the laws at issue
    here, and, in contrast to the case before us, the drilling
    operations at issue in Ventura County were subject to
    “detailed [federal] supervision” and an “extensive federal
    scheme reflecting concern for the local environment.”
    
    601 F.2d at 1084
    .
    3. Conflict Preemption: The Plaintiffs’ Argument That
    Senate Bill 3 Does Not Constitute Reasonable
    Environmental Regulation
    We have consistently held that Congress intended to
    permit reasonable environmental regulation of mining claims
    50            BOHMKER V. STATE OF OREGON
    on federal lands. In United States v. Weiss, 
    642 F.2d 296
     (9th
    Cir. 1981), for example, after considering the purposes
    underlying the Mining Act of 1872 and the Organic Act of
    1897, including 
    16 U.S.C. §§ 475
    , 478 and 551, we
    concluded:
    The Secretary of Agriculture has been given
    the responsibility and the power to maintain
    and protect our national forests and the lands
    therein. While prospecting, locating, and
    developing of mineral resources in the
    national forests may not be prohibited nor so
    unreasonably circumscribed as to amount to a
    prohibition, the Secretary may adopt
    reasonable rules and regulations which do not
    impermissibly encroach upon the right to the
    use and enjoyment of placer claims for mining
    purposes.
    
    642 F.2d at 299
    . In United States v. Shumway, 
    199 F.3d 1093
    (9th Cir. 1999), where we considered not only the Mining Act
    and the Organic Act but also the “endanger or materially
    interfere” standard embodied in 
    30 U.S.C. § 612
    (b), we once
    again held that “the Forest Service may regulate use of
    National Forest lands by holders of unpatented mining claims
    . . . to the extent that the regulations are ‘reasonable’ and do
    not impermissibly encroach on legitimate uses incident to
    mining and mill site claims.” 
    199 F.3d at 1107
    .
    Congress, moreover, clearly intended reasonable state
    environmental regulation to govern mining on federal lands.
    In Granite Rock, the Supreme Court held that “reasonable
    state environmental regulation is not pre-empted.” 
    480 U.S. at 589
    ; see also 
    id. at 593
    . The plaintiffs do not dispute that
    BOHMKER V. STATE OF OREGON                     51
    a reasonableness standard applies here, but they argue that
    Senate Bill 3 is preempted because it constitutes an
    unreasonable environmental regulation.
    The plaintiffs’ arguments regarding unreasonableness
    echo those we have already considered. They contend Senate
    Bill 3 is an unreasonable regulation because it prohibits a
    particular method of mining in designated habitat, rather than
    subjecting that mining to a “prescribed limit” or pollution
    standard, and because it allegedly was “enacted for reasons
    expressly beyond protection of the environment.” We have
    already addressed these arguments. The preemption analysis
    does not turn on a formalistic distinction between
    “prohibitory” and “regulatory” measures, and the plaintiffs’
    evidence does not create a genuine dispute as to Senate
    Bill 3’s important environmental purpose. We recognize that
    unreasonable, excessive or pretextual state environmental
    regulation that unnecessarily interferes with development of
    mineral resources on federal land may stand as an obstacle to
    the accomplishment of the full purposes and objectives of
    Congress. We agree with the United States, however, that in
    this case that line has not been crossed. As the government
    explains, “[a] state law such as [Senate Bill 3] that is clearly
    intended to protect the natural environment by prohibiting the
    use of particular mining methods or equipment in carefully[]
    designated locations is not so at odds with Congress’s
    purposes that it is preempted by federal law.” Brief of the
    United States as Amicus Curiae 2–3.
    4. The Plaintiffs’ Argument That Genuine Issues of
    Material Fact Preclude Summary Judgment
    The plaintiffs argue that genuine issues of material fact
    preclude summary judgment in favor of the state. For
    52               BOHMKER V. STATE OF OREGON
    purposes of our de novo review of the summary judgment
    record, however, we have viewed the evidence in the light
    most favorable to the plaintiffs, and we have assumed –
    solely for purposes of determining whether Oregon is entitled
    to judgment as a matter of law – that Senate Bill 3 will have
    a significant adverse impact on the mining operations of the
    plaintiffs, making it effectively impossible for at least some
    of them to recover the valuable mineral deposits present on
    their claims. The only material dispute is whether, assuming
    these facts, Senate Bill 3 is preempted. Because that issue is
    one of law, summary judgment is appropriate. See Inland
    Empire Chapter of Associated Gen. Contractors of Am. v.
    Dear, 
    77 F.3d 296
    , 299 (9th Cir. 1996) (holding a “finding of
    no preemption is a legal question”).16
    CONCLUSION
    The district court properly rejected the plaintiffs’
    preemption claims. We hold that Senate Bill 3 is not
    preempted by federal law. The judgment of the district court
    is therefore affirmed.
    AFFIRMED.

    Contrary to the dissent, we do not today question the validity of as-
    applied preemption challenges. Dissent 66 & n.7.
    BOHMKER V. STATE OF OREGON                              53
    N.R. SMITH, Circuit Judge, dissenting:
    The National Forest Management Act of 1976 (NFMA),
    Pub. L. No. 94-588, 
    90 Stat. 2949
     (1976), and the Federal
    Land Policy and Management Act of 1976 (FLPMA), Pub. L.
    No. 94-579, 
    90 Stat. 2743
     (1976), occupy the field of land use
    planning regulation on federal lands. Because the permanent
    ban on motorized mining in Oregon Senate Bill 3 does not
    identify an environmental standard to be achieved but instead
    restricts a particular use of federal land, it must be deemed a
    land use regulation preempted by federal law. See Cal.
    Coastal Comm’n v. Granite Rock Co., 
    480 U.S. 572
    , 586–88
    (1987). Therefore, I must dissent.
    I.
    Although technically an open question, there is little
    dispute that Congress has occupied the field of land use
    planning on federal lands through its enactment of NFMA
    and FLPMA.1 See 
    id. at 585
     (“For purposes of this discussion
    and without deciding this issue, we may assume that the
    combination of the NFMA and the FLPMA pre-empts the
    extension of state land use plans onto unpatented mining
    claims in national forest lands.”); 
    id.
     at 612–13 (Scalia, J.,
    dissenting) (“The Court is willing to assume that California
    lacks such authority on account of [NFMA] and [FLPMA]. I
    believe that assumption is correct.”).
    Field preemption arises when “federal law so thoroughly
    occupies a legislative field as to make reasonable the
    1
    The majority (like the court in Granite Rock) assumes this point
    without deciding it. I address the merits of the issue because it is necessary
    to my determination that federal law preempts Senate Bill 3.
    54             BOHMKER V. STATE OF OREGON
    inference that Congress left no room for the States to
    supplement it.” Nat’l Fed’n of the Blind v. United Airlines
    Inc., 
    813 F.3d 718
    , 733 (9th Cir. 2016) (internal quotation
    marks omitted) (quoting Cipollone v. Liggett Grp., Inc.,
    
    505 U.S. 504
    , 516 (1992)). “The essential field preemption
    inquiry is whether the density and detail of federal regulation
    merits the inference that any state regulation within the same
    field will necessarily interfere with the federal regulatory
    scheme.” Id. at 734. To make this determination, our cases
    require first “delineat[ing] the pertinent regulatory field.” Id.
    We have “emphasized the importance of delineating the
    pertinent area of regulation with specificity before proceeding
    with the field preemption inquiry.” Id. Here the pertinent field
    involves any land use regulation of federal lands.
    The next step in our analysis requires us to “survey the
    scope of the federal regulation within th[is] field.” Id. Here,
    the relevant statutes are NFMA and FLPMA. Taken together,
    these statutes establish a comprehensive regulatory regime for
    land use planning on federal lands, including the role of states
    in the planning process. First, NFMA vests the authority to
    enact federal land use plans with respect to forest service
    lands in the Secretary of Agriculture, and FLPMA vests the
    authority to enact federal land use plans with respect to all
    other federal land in the Secretary of the Interior. 
    16 U.S.C. § 1604
    (a) (“[T]he Secretary [of Agriculture] shall develop,
    maintain, and, as appropriate, revise land and resource
    management plans for units of the National Forest System
    . . . .”); 
    43 U.S.C. § 1712
    (a) (“The Secretary [of the Interior]
    shall, with public involvement and consistent with the terms
    and conditions of this Act, develop, maintain, and, when
    appropriate, revise land use plans which provide by tracts or
    areas for the use of the public lands. Land use plans shall be
    developed for the public lands regardless of whether such
    BOHMKER V. STATE OF OREGON                   55
    lands previously have been classified, withdrawn, set aside,
    or otherwise designated for one or more uses.”).
    Second, NFMA and FLPMA expressly designate the level
    of state participation contemplated by federal law. See
    
    16 U.S.C. § 1604
    (a); 
    43 U.S.C. § 1712
    (c)(9). NFMA requires
    “coordin[ation] with the land and resource management
    planning processes of State and local governments and other
    Federal agencies.” 
    16 U.S.C. § 1604
    (a). FLPMA requires
    similar coordination with states, but the requirement is
    limited “to the extent consistent with the laws governing the
    administration of public lands.” 
    43 U.S.C. § 1712
    (c)(9).
    Moreover, FLPMA directs that the Secretary of the Interior
    shall, to the extent he finds practical, keep
    apprised of State, local, and tribal land use
    plans; assure that consideration is given to
    those State, local, and tribal plans that are
    germane in the development of land use plans
    for public lands; assist in resolving, to the
    extent practical, inconsistencies between
    Federal and non-Federal Government plans,
    and shall provide for meaningful public
    involvement of State and local government
    officials, both elected and appointed, in the
    development of land use programs, land use
    regulations, and land use decisions for public
    lands, including early public notice of
    proposed decisions which may have a
    significant impact on non-Federal lands.
    
    Id.
     (emphasis added). As Justice Scalia noted in Granite
    Rock, agreeing (in his dissent) with the majority’s assumption
    of preemption, these “requirements would be superfluous,
    56            BOHMKER V. STATE OF OREGON
    and the limitation upon federal accommodation meaningless,
    if the States were meant to have independent land use
    authority over federal lands.” 
    480 U.S. at 613
     (Scalia, J.,
    dissenting).
    Thus, the combination of NFMA and FLPMA occupy the
    field of land use regulation on federal lands. Accordingly,
    federal law preempts the extension of any state land use
    planning regulation or ordinance onto federal lands. Arizona
    v. United States, 
    567 U.S. 387
    , 401 (2012) (“Where Congress
    occupies an entire field . . . even complementary state
    regulation is impermissible. Field preemption reflects a
    congressional decision to foreclose any state regulation in the
    area, even if it is parallel to federal standards.”).
    II.
    Assuming that NFMA and FLPMA occupied the field of
    federal land use regulation, Granite Rock identified the legal
    framework for determining whether state environmental
    regulation impermissibly enters the congressionally occupied
    field of federal land use planning. First, the Court identified
    the dividing line between environmental regulation and land
    use planning. “Land use planning in essence chooses
    particular uses for the land; environmental regulation, at its
    core, does not mandate particular uses of the land but requires
    only that, however the land is used, damage to the
    environment is kept within prescribed limits.” Granite Rock,
    
    480 U.S. at 587
    . The Court also made clear that the inquiry
    requires examination not simply of the text of the law, but of
    its practical effect. “The line between environmental
    regulation and land use planning will not always be bright;
    for example, one may hypothesize a state environmental
    BOHMKER V. STATE OF OREGON                     57
    regulation so severe that a particular land use would become
    commercially impracticable.” 
    Id.
    The plaintiff miners and mining organizations
    (collectively “the miners”) challenge Senate Bill 3 on both
    grounds. They assert that Senate Bill 3 impermissibly
    (A) identifies a particular use of the land that is prohibited
    without reference to an identifiable environmental standard
    and (B) renders mining within the identified zones
    impracticable. Both arguments have merit.
    A.
    Granite Rock instructs that “environmental regulation, at
    its core, . . . requires only that, however the land is used,
    damage to the environment is kept within prescribed limits.”
    
    Id.
     (emphasis added) By contrast land use regulation
    identifies or restricts “particular uses” of land. 
    Id.
    A brief review of the text of Senate Bill 3 reveals its true
    character as a land use regulation. The operative language
    reads “motorized in-stream placer mining may not be
    permitted to occur up to the line of ordinary high water in any
    river in this state containing essential indigenous anadromous
    salmonid habitat, from the lowest extent of essential
    indigenous anadromous salmonid habitat to the highest extent
    of essential indigenous anadromous salmonid habitat.”
    2017 Or. Laws ch. 300, § 4(2). The operative language
    identifies particular tracts of land and prohibits a particular
    use of these lands. The operative language does not identify
    a “prescribed limit[]” on “damage to the environment” that
    must be avoided “however the land is used.” Granite Rock,
    
    480 U.S. at 587
    . Accordingly, federal law preempts Senate
    58               BOHMKER V. STATE OF OREGON
    Bill 3 as an improper attempt to extend a state land use
    regulation onto federal land.
    The majority disagrees for four reasons: (1) Senate Bill 3
    permits non-motorized mining, (2) it is not located in the land
    use section of the Oregon state code, (3) it has an
    environmental purpose, and (4) it is reasonably tailored to
    accomplish the environmental purpose without unduly
    interfering with mining operations. The majority’s arguments
    lack merit for the reasons set forth below.
    1.
    The majority first asserts (without any citation or
    authority) that, because Senate Bill 3 restricts only one type
    of mining, it is not a land use planning regulation. The
    majority’s analysis not only conflicts with Supreme Court
    precedent in Granite Rock, but it also erases any clear line
    between land use planning and environmental regulation.
    The majority criticizes the Granite Rock principle that
    environmental regulation “at its core” “prescribe[s] limits” on
    “damage to the environment” (“however the land is used”).
    Granite Rock, 
    480 U.S. at 587

    The majority goes so far as to assert that the Granite Rock standard
    is somehow non-binding dicta. See Maj. at 31 (“Granite Rock does not
    hold that only standards, not restrictions on activities, are permissible
    environmental regulation.”). Granite Rock fully analyzed the distinction
    between environmental regulation and land use planning, and the
    framework it announced was necessary to its holding. 
    480 U.S. at
    585–89.
    Because the court assumed that land use planning regulation was
    preempted, it was necessary to decide whether California’s permitting
    system was a land use planning regulation or an environmental regulation.
    
    Id. at 586
    . The Court applied the Granite Rock framework and determined
    BOHMKER V. STATE OF OREGON                              59
    distinction is “formalistic” and “make[s] no sense.” Maj. at
    31. Yet, a line must be drawn, because “Congress has
    indicated its understanding of land use planning and
    environmental regulation as distinct activities.” Granite Rock,
    
    480 U.S. at 587
    .
    Far from being nonsense, the formalism of the Granite
    Rock line makes it clear and easy to apply in deciding facial
    challenges to state environmental laws.3 Moreover, the
    majority offers no alternative standard for drawing a line
    between environmental regulation (not ordinarily preempted)
    and land use regulation (always preempted). Without a
    standard, the majority has no basis to reject the miners’
    challenge.
    that California’s permit system was a means of identifying environmental
    standards to be applied to the mining operation, not an attempt to regulate
    particular uses of the land at issue. See 
    id. at 586
     (“While the [California
    law] gives land use as well as environmental regulatory authority to the
    Coastal Commission, the state statute also gives the Coastal Commission
    the ability to limit the requirements it will place on the permit. . . . Since
    the state statute does not detail exactly what state standards will and will
    not apply in connection with various federal activities, the statute must be
    understood to allow the Coastal Commission to limit the regulations it will
    impose in those circumstances.” (emphasis added)). This is plainly
    sufficient to bind our decision here. Cf. Cetacean Cmty. v. Bush, 
    386 F.3d 1169
    , 1173 (9th Cir. 2004) (“[W]here a panel confronts an issue germane
    to the eventual resolution of the case, and resolves it after reasoned
    consideration in a published opinion, that ruling becomes the law of the
    circuit, regardless of whether doing so is necessary in some strict logical
    sense.” (citation omitted)).
    3
    The suction hose size and vehicle weight hypotheticals raised by the
    majority are not difficult cases under the clear line drawn in Granite Rock.
    Neither regulation identifies an environmental standard to be achieved.
    60               BOHMKER V. STATE OF OREGON
    Specifically, the majority’s suggestion that the law is
    permissible because it regulates only one means of mining
    begs the question of the appropriate level of generality at
    which a law must prohibit a particular use to be deemed a
    land use planning regulation. Does land use planning involve
    only broad categories of uses, for example commercial versus
    noncommercial uses? Or can land use planning also include
    dividing tracts for commercial fishing from those for
    commercial mining? Would a law prohibiting the use of any
    mining tools (motorized or not) within identified zones
    amount to environmental regulation or land use planning?
    What if the law also required miners to tie one hand behind
    their backs? The majority’s bare assertion that prohibiting a
    type of mining does not amount to regulating “particular uses
    for the land” fails to articulate a meaningful standard and flies
    in the face of framework set forth in Granite Rock. 
    480 U.S. at 587
    .4
    The premise of the majority’s insistence that the Granite
    Rock line is nonsense also lacks merit. See Maj. at 31. In
    4
    The majority notes that many of the miners are still able to mine
    other portions of their claims or are still permitted to mine by hand in the
    zones covered by the law. I know of no authority for the proposition that
    a law ceases to be a land use plan simply because it governs only a subset
    of land, and not all land. Indeed, most land use plans divide land into
    different zones prescribing a different set of permissible uses for each
    zone. Accordingly, the fact that some miners have in-stream as well as
    out-of-stream operations (or operations inside and outside of essential
    salmonid habitat) matters not at all in our determination of whether Senate
    Bill 3 is a land use regulation. Likewise, the fact that the law permits
    mining by hand does not mean its prohibition on motorized mining is not
    a land use ordinance. Land use plans regulate particular uses all the time.
    For example, a land use plan might specify that within a residential
    neighborhood in-home businesses are permitted, but office buildings are
    not.
    BOHMKER V. STATE OF OREGON                    61
    addition to being clear, the line drawn in Granite Rock serves
    important functions. For example, standards identify an
    environmental end to be achieved and offer a means of
    measuring the degree to which a particular use conflicts with
    an environmental objective. They are also facially neutral
    towards varying uses of the land. The majority is right that
    environmental regulations certainly can impact mining
    practicability. But the Supreme Court made clear that this
    impact matters only in the exceptional circumstance where an
    environmental standard is “so severe” as to render any mining
    within an identified zone “commercially impracticable.” See
    Granite Rock, 
    480 U.S. at 587
    . The possibility of a narrow
    exception, does not eliminate the value of the general rule. I
    address this narrow exception in greater detail in Part II.B.
    The Supreme Court meaningfully considered the difficult
    issue of how to discern land use regulations from
    environmental ones. The majority errs in failing to follow its
    instruction. Applying the Granite Rock framework here,
    Senate Bill 3 is a land use regulation that is preempted as
    applied to federal lands.
    2.
    The majority next asserts that Senate Bill 3 is not a land
    use regulation, because it is codified outside the sections of
    the Oregon Code governing land use planning. However, I
    know of no canon of construction (and the majority cites
    none) that suggests that a law’s placement within the code
    can override the substantive import of its text. Further, there
    are other Oregon land use statutes outside the code sections
    the majority identifies. See, e.g., 
    Or. Rev. Stat. § 390.250
    (authorizing land use planning “to promote the public scenic,
    park and recreational use of lands along Bear Creek”); Or.
    62               BOHMKER V. STATE OF OREGON
    Rev. Stat.§ 390.308 (authorizing land use planning to
    complete the “Oregon Coast Trail”); 
    Or. Rev. Stat. § 390.112
    (“The State Parks and Recreation Department shall propose
    to the State Parks and Recreation Commission additional
    criteria for the acquisition and development of new historic
    sites, parks and recreation areas.”).
    3.
    The majority next asserts that Senate Bill 3 is an
    environmental regulation because of its “obvious and
    important environmental purpose.” Maj. at 32. To be sure,
    the prefatory language in Senate Bill 3 identifies an
    environmental purpose “to protect indigenous anadromous
    salmonids and habitat essential to the recovery and
    conservation of Pacific lamprey.” 2017 Or. Laws ch. 300,
    § 4(2).5 But many land use plans have environmental
    5
    The majority also cites legislative findings that “[m]ining that uses
    motorized equipment in the beds and banks of the rivers of Oregon can
    pose significant risks to Oregon’s natural resources, including fish and
    other wildlife, riparian areas, water quality, the investments of this state
    in habitat enhancement and areas of cultural significance to Indian tribes.”
    2013 Or. Laws ch. 783, § 1(4). Maj. at 33. Yet there is little substance to
    this finding. The legislature identified only the possibility of
    environmental harm because it used the language “can pose significant
    risks.” Id. (emphasis added). Almost anything “can pose significant risks”
    to the environment. Nothing in these findings suggests that any form of
    motorized mining necessarily causes an adverse effect on wildlife
    resources. Like the prefatory language in Senate Bill 3, this language does
    not purport to identify an environmental standard to be achieved. The
    same is true for the majority’s other citations to Oregon law. See Maj. at
    32.
    BOHMKER V. STATE OF OREGON                           63
    purposes as well.6 Systems of national parks, state parks, and
    designated wilderness areas are prime examples of land use
    planning aimed at accomplishing obvious and important
    environmental purposes.
    Here, the means of accomplishing the environmental
    purpose undisputedly prohibit a particular use of the land,
    without reference to an environmental standard to be
    achieved. Unlike the permit system in Granite Rock, this law
    does not involve a flexible regime that “must be understood
    to allow [Oregon] to limit the regulations it will impose” in
    a manner consistent with allowing permissible federal mining
    to continue. See Granite Rock, 
    480 U.S. at 586
    .
    In contrast to Senate Bill 3, the federal regulations
    governing mining on public lands cited by the majority are
    good examples of standards based environmental regulation.
    Maj. at 22. Each identifies environmental standards to be
    achieved, rather than particular uses to be prohibited. See,
    e.g., 
    36 C.F.R. § 228.8
     (identifying federal and state air,
    water, and solid waste standards that must be complied with
    and requiring operators to “take all practicable measures to
    maintain and protect fisheries and wildlife habitat which may
    be affected by the operations” (emphasis added)); 
    43 C.F.R. § 3809.3
     (requiring operators to follow “a higher standard”
    under state law if one has been enacted (emphasis added));
    
    43 C.F.R. § 3809.420
    (b) (identifying federal and state air,
    water, and solid waste standards that must be complied with
    6
    As the majority notes, purpose is certainly relevant to our
    preemption analysis. See Maj. at 32 n.9. But nothing in our cases suggests
    that a genuine purpose can innoculate a law that substantively intrudes on
    a field preempted by Congress. The majority’s emphasis on purpose
    proves too little.
    64            BOHMKER V. STATE OF OREGON
    and requiring operators to “take such action as may be needed
    to prevent adverse impacts to threatened or endangered
    species, and their habitat which may be affected by
    operations” (emphasis added)).
    Simply, the environmental purpose behind Senate Bill 3
    does not identify an environmental standard. Indeed, nothing
    in the law’s text (or the record in this case) indicates that
    motorized mining—in any form or at any scale—necessarily
    causes harm to indigenous anadromous salmonids or Pacific
    lamprey. On its face, Senate Bill 3 would prohibit a
    motorized mining operation irrespective of the miner’s
    compliance with all state and federal environmental
    standards, including the federal Endangered Species Act,
    National Environmental Policy Act, and Clean Water Act.
    This remains true, even if federal (or state) environmental
    review determines that the net effect of a motorized-mining
    operation is positive for anadromous salmonids and Pacific
    lamprey. Senate Bill 3 simply mandates that—irrespective of
    the actual environmental impact—motorized mining is a
    prohibited use of land in the identified zones. Congress has
    preempted this type of intrusion into the field of federal land
    use planning.
    4.
    Lastly, the majority persistently makes the bare assertion
    that federal law does not preempt Senate Bill 3, because it is
    “tailored to” its environmental purpose. See Maj. at 27
    (asserting (without elaboration) that the law is “tailored to
    achieve its environmental purpose without unduly interfering
    with mining operations”); Maj. at 35 (concluding that Senate
    Bill 3 “is tailored” to its environmental purpose). The
    majority cites no legal authority (and I am aware of none) for
    BOHMKER V. STATE OF OREGON                      65
    the proposition that federal preemption analysis includes an
    assessment of the fit between the substance of a state law and
    its stated purpose.
    Further, the majority fails to explain how it reaches its
    reasonably tailored conclusion. As to the merits of the
    majority’s conclusion that the law is reasonably tailored, I
    have my doubts. First, the parties have not argued the issue
    one way or the other.
    Second, the tailoring issue necessarily turns on facts that
    are disputed or not in evidence, including the extent to which
    motorized mining negatively impacts fish habitat and whether
    there are some means of motorized mining that would not
    adversely impact fish habitat. A tailoring analysis would
    involve actually assessing the degree to which a law advances
    its stated purpose (i.e. the state’s interest). Cf., e.g., Italian
    Colors Rest. v. Becerra, 
    878 F.3d 1165
    , 1178 (9th Cir. 2018)
    (discussing narrow tailoring as an analysis focused on the
    degree of fit between ends and means). Yet, the majority
    appears to use the laws’ stated purpose as the premise for its
    reasonable tailoring conclusion. Good intentions are never
    enough to establish that a law is properly tailored. Cf. 
    id.
    (striking down a commercial speech restriction because there
    were alternatives that “would restrict less speech and would
    more directly advance California’s asserted interest in
    preventing consumer deception”).
    It remains unclear to me how a tailoring analysis aids us
    in deciding the preemption question. But to the extent the
    inquiry is relevant, the obvious and less restrictive regulation
    here would be to simply require that mining activity in
    essential habitat areas be conducted in a manner that does not
    adversely affect fish habitat—thus prohibiting non-motorized
    66               BOHMKER V. STATE OF OREGON
    mining adverse to fish populations and permitting motorized
    mining that can be conducted consistent with requirement to
    preserve essential habitat.
    B.
    Federal law not only preempts Senate Bill 3 on its face,
    but the miners also identified disputed issues of material fact
    precluding summary judgment on their Granite Rock as-
    applied preemption challenge. Contrary to the majority’s
    suggestion, Maj. at 50, the law recognizes as-applied
    preemption challenges that turn on the effect in operation of
    the allegedly preempted state law. Gade v. Nat’l Solid Wastes
    Mgmt. Ass’n, 
    505 U.S. 88
    , 105 (1992) (“Although ‘part of the
    pre-empted field is defined by reference to the purpose of the
    state law in question, . . . another part of the field is defined
    by the state law’s actual effect.’” (alterations in original)
    (quoting English v. Gen. Elec. Co., 
    496 U.S. 72
    , 84 (1990)));
    
    id.
     (“In assessing the impact of a state law on the federal
    scheme, we have refused to rely solely on the legislature’s
    professed purpose and have looked as well to the effects of
    the law.”).7
    7
    Many other cases recognize as-applied preemption challenges. See,
    e.g., Gobeille v. Liberty Mut. Ins. Co., 
    136 S. Ct. 936
    , 943–45 (2016)
    (identifying factual issues like the “‘acute, albeit indirect, economic
    effects’ of [a] state law” as one mechanism for showing a state law is
    preempted by ERISA (citation omitted)); Adrian & Blissfield R.R. Co. v.
    Vill. of Blissfield, 
    550 F.3d 533
    , 540 (6th Cir. 2008) (identifying
    circumstances for proving a law is “preempted as applied” and

    for consideration of the as-applied preemption challenge), with Puente

    2016 WL 6873294
    , at
    BOHMKER V. STATE OF OREGON                           67
    Granite Rock expressly recognized this possibility in the
    context of state environmental regulation versus land use
    planning. 
    480 U.S. at 587
    . As the court noted, “[t]he line
    between environmental regulation and land use planning will
    not always be bright; for example, one may hypothesize a
    state environmental regulation so severe that a particular land
    use would become commercially impracticable.” 
    Id.
     The
    Court went on to endorse “reasonable state environmental
    regulation” as not preempted by federal law. 
    Id. at 589
    .
    Whether dicta or holding, these statements by the Supreme
    Court reach the correct conclusion. Because Congress has
    occupied the field of land use planning, federal law preempts
    any environmental regulation that (when applied to federal
    land) has the effect of prohibiting (for all practical purposes)
    a particular land use in the regulated zone. To hold otherwise
    would allow an end-run around federal preemption.
    Here, the miners contend that mining without motors is (if
    not impossible) entirely impracticable within the in-stream
    zones governed by Senate Bill 3. Thus, they argue the law has
    the effect of prohibiting mining within the regulated area. At
    oral argument, the State essentially conceded this fact. United
    States Court of Appeals for the Ninth Circuit, 16-35262

    25:00 (acknowledging that Senate Bill 3 effectively prohibits
    mining in the in-stream areas governed by the law). Thus, the
    miners argue that entry of summary judgment is
    inappropriate.

    analysis and concluding that the law was field preempted as applied to a
    narrow set of prohibited conduct).
    68                BOHMKER V. STATE OF OREGON
    The majority suggests that the miners waived this
    challenge because they “do not argue that Senate Bill 3 is
    preempted simply because it may render some of their mining
    claims commercially impracticable.” Maj. at 27–28. Come
    on. That cannot be the basis for our decision. The record
    amply establishes that the miners have consistently raised
    both a facial and as-applied challenge to Senate Bill 3 before
    the district court and on appeal. Excerpts of R. at 102, 106-
    07, 118, 121, 124, 130, 135, 143, 150 (identifying declaration
    testimony by the miners regarding the impact of the law on
    practicability of mining in the zones governed by Senate
    Bill 3 that was provided to the district court in opposition to

    the practicability of mining is an alternative basis for the
    court to conclude under Granite Rock that federal law
    preempts Senate Bill 3).8
    8
    The majority doubles down on its erroneous conclusion that the
    miners have waived an as-applied challenge to Senate Bill 3. In support
    of its conclusion, the majority cites a single line in the miners’ reply
    stating that “[t]his appeal is not about profitability, but about prohibition.”
    Maj. at 28 n.6 (citing Reply Br. at 41). Nothing in the quoted language
    BOHMKER V. STATE OF OREGON                           69
    The majority next rejects the merits of an as-applied
    theory of preemption, asserting that considerations of
    commercial practicability would endanger every
    environmental regulation. Not so.
    We are presented with a narrow but important issue of
    preemption. Even if federal law preempts Oregon’s attempt
    to apply Senate Bill 3 to federal lands, the miners must still
    comply with all environmental laws and standards imposed
    expressly by federal statutes and regulations. The Granite
    Rock practicability exception does not apply to federal
    regulation. Cf., e.g., Clouser v. Espy, 
    42 F.3d 1522
    , 1530 (9th
    Cir. 1994) (affirming forest service access regulation that
    diminished value of mining claims). Moreover, Oregon
    remains free to coordinate its land use plans with the relevant
    federal agencies in seeking an outright federal prohibition on
    mining within essential habitat on federal lands. Oregon may
    also amend its statute to incorporate an environmental
    standard to require mining activity in essential habitat be
    conducted in a manner that avoids damage to fish habitat. In
    short, a win for the miners is not likely to lead to
    environmental disaster as the majority portends.
    Second, commercial practicability is a judicially
    manageable standard. “[V]irtually every environmental
    regulation” is not at risk. See Maj. at 28–29. Contrary to the
    forecloses the argument that Senate Bill 3 effectively functions as a
    prohibition in the regulated zones. Waiver requires an “intentional
    relinquishment of a known right.” E.g., Oelbermann v. Toyo Kisen
    Kabushiki Kaisha, 
    3 F.2d 5
    , 5 (9th Cir. 1925) (citation omitted). The
    miners have consistently argued that Senate Bill 3 makes it effectively
    impossible to remove minerals from their claims. In concluding that the
    issue is waived, the majority simply ignores the substantial briefing and
    argument cited above.
    70            BOHMKER V. STATE OF OREGON
    majority’s assertion, nothing in Granite Rock suggests a case-
    by-case, miner-by-miner assessment of commercial
    practicability. Rather, Granite Rock suggests an approach
    focused on the overall effect of the state regulation on mining
    practicability. See Granite Rock, 
    480 U.S. at
    586–89.
    The exception applies only where the regulation’s effect
    is “so severe” that it renders mining on the regulated lands
    “commercially impracticable” as a general matter. The
    finances or circumstances of individual miners are not
    relevant to the analysis. A court simply examines the effect
    of the regulation on the scope of commercial mining
    operations that could permissibly be employed in the absence
    of the regulation. Where a state environmental regulation
    eliminates all previously permissible means of commercial
    mining on federal land, it runs afoul of the Granite Rock
    exception. If viable means of commercial mining remain
    available in most (if not all) tracts of land governed by the
    regulation, it falls within the general rule that “reasonable
    state environmental regulation is not pre-empted . . . .” 
    Id. at 589
    .
    Here, the miners identified sufficient factual support for
    the proposition that Senate Bill 3 renders mining
    commercially impracticable within the areas regulated by the
    statute. I cannot agree with the majority’s assertion that
    Senate Bill 3 is not a de facto ban on mining because it allows
    non-motorized mining (i.e. panning for gold by hand). This
    would be similar to saying to a man that he is not prohibited
    from building a house on his property, he is only prohibited
    from using any power tools, trucks, or other motorized
    equipment in doing so. In an imaginary world, it is certainly
    still possible that over the course of his life he could dig the
    foundation, mix the concrete, haul the lumber, and construct
    BOHMKER V. STATE OF OREGON                     71
    a house eventually. Nonetheless, such a law would render the
    man’s right to build a house a nullity. If the miners proved
    impracticability on remand, I would conclude that the Oregon
    law is a de facto land use regulation preempted by federal
    law.
    III.
    In short, there are two alternative grounds to reverse the
    district court. First, the miners are entitled to summary
    judgment because federal law preempts Oregon’s
    impermissible attempt to regulate particular uses of federal
    land under Senate Bill 3. Alternatively, I would recognize the
    as-applied theory for establishing preemption outlined in
    Granite Rock. Federal law preempts environmental regulation
    that is so severe that it operates as a de facto land use plan by
    rendering a particular use of the regulated land utterly
    impracticable. The miners put on sufficient evidence to
    establish at least a genuine issue for trial on this theory.
    Accordingly, I respectfully dissent from the majority’s
    decision to affirm summary judgment in favor of the State of
    Oregon.
