    Appeal from the United States District Court
    for the Northern District of California
    William Alsup, District Judge, Presiding
    Argued and Submitted December 10, 2021

    Opinion by Judge W. Fletcher
    SUMMARY*
    Preemption / Federal Communications Commission
    The panel affirmed the district court’s summary judgment
    for Apple Inc., based on preemption of the state-law claims
    by federal law, in an action bought by plaintiffs, who are
    iPhone users, alleging that Apple breached state tort and
    consumer-fraud laws by misrepresenting and failing to
    disclose the amount of radiofrequency (“RF”) radiation
    emitted by iPhones.
    A regulatory scheme established by a Federal
    Communications Commission 1996 RF Order set exposure
    limits that included cell phones, and it remains largely intact
    *
    This summary constitutes no part of the opinion of the court. It has
    been prepared by court staff for the convenience of the reader.
    COHEN V. APPLE                          3
    today. Plaintiffs alleged that RF radiation emitted by iPhones
    regularly exceeded the federal exposure limit, and they
    brought eight claims against Apple under state tort and
    consumer-fraud laws. The district court held that plaintiffs’
    state-law claims were preempted by federal law.
    The panel held that the Hobbs Act did not deprive the
    district court of jurisdiction. The panel rejected Apple’s
    argument that the Hobbs Act broadly granted exclusive
    jurisdiction to courts of appeals over private suits that
    implicated the substance of agency determinations, and
    divested district courts of jurisdiction to pass on any issue
    that would require them to decide on a determination made in
    an FCC final order. Plaintiffs in this case did not challenge
    the validity of any of the FCC’s final orders, either directly or
    indirectly. The issue in this case was whether the FCC’s
    concededly valid orders had preemptive effect. A holding
    that the FCC orders do, or do not, preempt plaintiffs’ state-
    law claims had no effect on their validity.
    Turning to the merits of the appeal, the panel first
    addressed plaintiffs’ argument that the FCC promulgated its
    RF Orders under the National Environmental Policy Act
    (“NEPA”), which was a purely procedural statute with no
    preemptive force, and therefore regulations promulgated
    under NEPA did not preempt plaintiffs’ state-law causes of
    action. The panel agreed with plaintiffs that NEPA was a
    purely procedural statute and that it had no preemptive force.
    However, the panel did not agree with plaintiffs that the
    FCC’s RF Orders were promulgated under NEPA. The panel
    held that the twin Communications Acts, the
    Communications Act of 1934 and the Telecommunications
    Act of 1996, granted to the FCC broad regulatory powers
    over wireless communications devices. The 1996 Act
    4                      COHEN V. APPLE
    directed the FCC to complete rulemaking for RF radiation
    that had already been initiated under the 1934 Act. NEPA, by
    contrast, granted no affirmative regulatory powers over
    wireless communications.
    Next, plaintiffs argued that even if the FCC’s RF Orders
    were promulgated under either, or both, of the two
    Communications Acts, the savings clauses in those Acts
    preserved their state-law causes of action. Specifically, first,
    plaintiffs argued that the 1934 Act did not authorize
    preemption by regulations promulgated under the Act, and
    therefore their state-law causes of action were not preempted
    by the FCC’s Orders. The panel held that a federal statute
    need not specify its preemptive force in order for the statute
    to have such a force, and Congress did not need to expressly
    delegate preemptive authority to the FCC for its regulations
    to preempt state law. The operative question was whether the
    agency meant to preempt the state law. The intent to preempt
    need not be express. Under the doctrine of implied conflict
    preemption, the agency’s statutorily authorized regulations
    will preempt any conflicting state or local law. The panel held
    that the conflict between the FCC’s RF radiation regulations
    and plaintiffs’ state law claims posed a sufficient obstacle to
    the full accomplishment of the FCC’s objectives. The
    savings clause in § 414 of the 1934 Act did not help
    plaintiffs. The panel concluded that the FCC’s regulations
    under the 1934 Act, setting upper limits on the levels of
    permitted RF radiation, preempted state laws that imposed
    liability premised on levels of radiation below the limits set
    by the FCC.
    Second, plaintiffs argued that the preemptive scope of the
    FCC’s radiation regulations could not be determined solely
    by consulting the 1934 Act. The panel disagreed, and held
    COHEN V. APPLE                        5
    that the scope of preemption of the FCC’s RF regulations was
    controlled by the 1934 Act, and the preemption provisions of
    the 1996 Act were irrelevant. The savings clause in Section
    332(c)(7)(A) of the 1996 Act was a narrowly focused savings
    clause and had nothing to do with RF radiation emissions
    from cell phones. The general savings clause in Section 601
    of the 1996 Act by its very terms applied only to the 1996 Act
    and does not apply to the 1934 Act.

    OPINION
    W. FLETCHER, Circuit Judge:
    Cell phones emit radiofrequency (“RF”) radiation in the
    course of their ordinary operation. Pursuant to the
    Communications Act of 1934 and the Telecommunications
    Act of 1996 (“twin Communications Acts”), the Federal
    Communications Commission (“FCC”) has promulgated
    regulations establishing RF radiation standards for cell
    phones.
    Plaintiffs-appellants (“plaintiffs”) Andrew Cohen and
    other individuals are users of iPhones manufactured by
    defendant-appellee Apple Inc. Plaintiffs brought suit against
    Apple in the district court, alleging that Apple breached state
    tort and consumer-fraud laws by misrepresenting and failing
    to disclose the amount of RF radiation emitted by iPhones.
    The district court entered summary judgment for Apple,
    holding that the plaintiffs’ state-law claims are preempted by
    federal law.
    We have jurisdiction under 
    28 U.S.C. § 1291
     and affirm.
    We hold that the district court had subject matter jurisdiction
    and that plaintiffs’ claims are preempted.

    I. Background
    We begin with an overview of RF radiation, of the
    relevant statutory structure, and of FCC regulation of devices
    that emit RF radiation.
    A. RF Radiation
    Like radios and televisions, cell phones rely on
    radiofrequency electromagnetic waves, otherwise known as
    RF radiation, to receive signals. Cell phones also emit RF
    radiation to send signals. RF radiation is a subset of
    electromagnetic radiation.       There are two forms of
    electromagnetic radiation: ionizing and non-ionizing.
    Ionizing radiation can be extremely dangerous. Among other
    things, it can alter a person’s DNA. Non-ionizing radiation
    is much less dangerous and is incapable of damaging DNA.
    However, high levels of non-ionizing RF radiation can cause
    biological effects by increasing the temperature of tissues.

    ic-compatibility-division/radio-frequency-safety/faq/rf-safety
    [https://perma.cc/DD6C-3SGM] (last visited July 18, 2022).
    For example, RF radiation is used to heat food in microwave
    ovens. 
    Id.
     Cell phones emit non-ionizing RF radiation, but
    not at high enough levels to cause thermal effects. 
    Id.
    The effects of non-thermal RF radiation on human health
    are controverted. 
    Id.
     While some studies have described
    adverse biological effects resulting from exposure to low
    levels of RF radiation at levels emitted by cell phones, many
    of these effects could not be replicated in later studies. 
    Id.
    Current FCC regulations for cell phones set RF radiation
    8                     COHEN V. APPLE
    limits far below the level at which adverse biological effects
    in laboratory animals have been observed.
    B. Statutory Background
    Congress created the FCC through the Communications
    Act of 1934 (“1934 Act”), Pub. L. No. 73-416, 
    48 Stat. 1064
    (codified as amended at 
    47 U.S.C. § 151
     et seq.). The 1934
    Act, as amended, instructed the FCC “to make available . . .
    a rapid, efficient, Nation-wide, and world-wide wire and
    radio communication service with adequate facilities at
    reasonable charges,” for three purposes: (1) national defense,
    (2) “promoting safety of life and property through the use of
    wire and radio communications,” and (3) “securing a more
    effective execution of this policy by centralizing authority”
    previously granted to multiple agencies and “granting
    additional authority with respect to interstate and foreign
    commerce in wire and radio communication.” 
    47 U.S.C. § 151
    . The 1934 Act, as amended, declared it a national
    policy “to encourage the provision of new technologies and
    services to the public.” 
    Id.
     § 157(a).
    The 1934 Act “endowed the [FCC] with comprehensive
    powers to promote and realize the vast potentialities of
    radio.” Nat’l Broad. Co. v. United States, 
    319 U.S. 190
    , 217
    (1943). The Act, as amended, authorized the FCC to “[m]ake
    such rules and regulations and prescribe such restrictions and
    conditions, not inconsistent with law, as may be necessary to
    carry out the [statutory] provisions.” 
    47 U.S.C. § 303
    (r); see
    also 
    id.
     § 154(i) (“The Commission may perform any and all
    acts, make such rules and regulations, and issue such orders,
    not inconsistent with this chapter, as may be necessary in the
    execution of its functions.”). The 1934 Act also authorized
    the FCC, “as public convenience, interest, or necessity
    COHEN V. APPLE                          9
    requires,” to “[r]egulate the kind of [radio] apparatus to be
    used with respect to its external effects and the purity and
    sharpness of the emissions from each station and from the
    apparatus therein.” Id. § 303(e).
    The 1934 Act contains a general savings clause. It
    provides: “Nothing in this chapter contained shall in any way
    abridge or alter the remedies now existing at common law or
    by statute, but the provisions of this chapter are in addition to
    such remedies.” Id. § 414.
    In 1996, Congress passed the Telecommunications Act
    (“1996 Act”). Telecommunications Act of 1996, Pub. L. No.
    104-104, 
    110 Stat. 56
    . When the 1996 Act was passed, the
    FCC had initiated but had not completed a rulemaking
    proceeding concerning RF radiation. The 1996 Act directed
    the FCC to “complete action . . . to prescribe and make
    effective rules regarding the environmental effects of radio
    frequency emissions” within 180 days after the enactment of
    the Act. 
    Id.
     § 704(b), 110 Stat. at 152.
    The 1996 Act limits the FCC’s authority where its
    regulations would conflict with state and local land-use
    regulations. A specific savings clause provides, “[N]othing
    in this chapter shall limit or affect the authority of a State or
    local government or instrumentality thereof over decisions
    regarding the placement, construction, and modification of
    personal wireless service facilities.”              
    47 U.S.C. § 332
    (c)(7)(A). The Conference Report of the 1996 Act
    describes § 332(c)(7) as “prevent[ing FCC] preemption of
    local and State land use decisions and preserv[ing] the
    authority of State and local governments over zoning and
    land use matters.” H.R. Rep. No. 104-458, at 207–08 (1996)
    (Conf. Rep.). That is, the limitation placed on the FCC’s
    10                     COHEN V. APPLE
    preemptive powers by § 332(c)(7) “relate[s] to local land use
    regulations and [is] not intended to limit or affect the
    Commission’s general aut hori t y over radi o
    telecommunications, including the authority to regulate the
    construction, modification and operation of radio facilities.”
    Id. at 209.
    The 1996 Act also contains a general savings clause. It
    provides: “This Act and the amendments made by this Act
    shall not be construed to modify, impair, or supersede
    Federal, State, or local law unless expressly so provided in
    such Act or amendments.” 1996 Act § 601(c)(1), 110 Stat. at
    143. The savings clause is not codified in the United States
    Code, but is included as part of the notes to 
    47 U.S.C. § 152
    .
    The Hobbs Act governs judicial review of FCC final
    orders. Under the Hobbs Act, federal courts of appeals
    (except the Federal Circuit) have “exclusive jurisdiction to
    enjoin, set aside, suspend (in whole or in part), or to
    determine the validity of,” inter alia, “all final orders of the
    Federal Communications Commission made reviewable by
    [
    47 U.S.C. § 402
    (a)].” 
    28 U.S.C. § 2342
    ; see also 
    47 U.S.C. § 402
    (a) (providing judicial review of the FCC’s orders and
    decisions, including “[a]ny proceeding to enjoin, set aside,
    annul, or suspend any order of the [FCC]”).
    FCC regulatory actions are subject to the National
    Environmental Policy Act (“NEPA”). For “[f]ederal actions
    significantly affecting the quality of the human environment,”
    NEPA requires federal agencies to include “a detailed
    statement” regarding the “environmental impact of the
    proposed action.” 
    42 U.S.C. § 4332
    (2)(C)(i). NEPA “does
    not mandate particular results” but “imposes only procedural
    requirements on federal agencies with a particular focus on
    COHEN V. APPLE                          11
    requiring agencies to undertake analyses of the environmental
    impact of their proposals and actions.” Dep’t of Transp. v.
    Pub. Citizen, 
    541 U.S. 752
    , 756–57 (2004) (first quoting
    Robertson v. Methow Valley Citizens Council, 
    490 U.S. 332
    ,
    350 (1989); and then citing 
    id.
     at 349–50). Because the
    licensing of equipment that emits RF radiation may
    significantly affect the environment, NEPA obligates the FCC
    in such cases to consider the environmental impact of its
    proposed actions with respect to licensing.
    C. FCC Regulation of Devices that Emit RF Radiation
    In 1979, the FCC issued a notice of inquiry (“1979 Notice
    of Inquiry”) to gather information relevant to “its regulatory
    responsibility to promote communications by radio in light of
    the increased concern about the biological effects of radio
    frequency radiation.” In re Responsibility of the Federal
    Communications Commission to Consider Biological Effects
    of Radio Frequency Radiation When Authorizing the Use of
    Radio Frequency Devices, 
    72 F.C.C.2d 482
    , 482, ¶ 1 (June
    15, 1979).
    The 1979 Notice of Inquiry was based on the FCC’s
    responsibilities under two statutes. First, the 1934 Act directs
    the FCC “to promote the use of radio communications service
    . . . as the public convenience, interest, or necessity requires,”
    and imposes on the FCC the “statutory obligation to make
    available, so far as possible a rapid efficient communication
    service at reasonable charges and to prevent interference
    between stations.” 
    Id.
     at 487–88, 489, ¶¶ 12, 16 (internal
    ellipses and quotation marks omitted). The FCC noted that,
    in fulfilling its statutory mandate under the 1934 Act, “[a]
    balance must be achieved between serving the public interest
    by fulfilling its needs for communications services and
    12                    COHEN V. APPLE
    adequately protecting the populace against potentially adverse
    biological effects that may be attributable to excessive RF
    radiation.” 
    Id. at 489, ¶ 17
    . Second, the FCC was required to
    comply with NEPA.            The FCC noted its “explicit
    responsibilities under NEPA.” 
    Id. at 488, ¶ 13
    .
    In 1982, pursuant to its 1979 Notice of Inquiry, the FCC
    issued a notice of proposed rulemaking (“1982 NPRM”)
    regarding the biological effects of RF radiation. In re
    Responsibility of the Federal Communications Commission
    to Consider Biological Effects of Radiofrequency Radiation
    When Authorizing the Use of Radiofrequency Devices,
    
    89 F.C.C.2d 214
     (Feb. 18, 1982). The 1982 NPRM proposed
    expanding the definition of “major actions” that would
    subject RF radiation-emitting devices to FCC licensing
    requirements. 
    Id. at 215, ¶ 2
    . The FCC identified the “legal
    basis” for its 1982 NPRM as follows:
    The action proposed is based on the
    obligations imposed on the [FCC] by the
    National Environmental Policy Act of 1969
    and is in furtherance of §§ 4(i) and 303(r) of
    the Communications Act of 1934, as
    amended, which permits the [FCC] to make
    rules and regulations not inconsistent with
    other existing laws, as may be necessary in
    the execution of its functions, with the
    additional view of securing the public welfare.
    Id. pt. VI(3), at 255 (citation omitted). The 1982 NPRM
    acknowledged that NEPA required the FCC “to consider
    whether the equipment and operations it authorizes will
    ‘significantly affect the quality of the human environment.’”
    Id. at 251, ¶ 183 (quoting 
    42 U.S.C. § 4332
    (2)(c)).
    COHEN V. APPLE                       13
    In 1985, the FCC issued an order (“1985 RF Order”)
    amending its “rules implementing” NEPA.                 In re
    Responsibility of the Federal Communications Commission
    to Consider Biological Effects of Radiofrequency Radiation
    When Authorizing the Use of Radiofrequency Devices, 
    100 F.C.C.2d 543
    , 543, ¶ 1 (Mar. 14, 1985). The 1985 RF Order
    adopted the 1982 Radio Frequency Protection Guides drafted
    by the American National Standards Institute (“ANSI”). Id.;
    see 
    id. at 547, ¶ 9
    . In adopting the ANSI guidelines as a
    standard, the FCC noted: “Although we have neither the
    expertise nor the jurisdiction to develop our own radiation
    exposure guidelines, we believe . . . that the [FCC] does have
    the expertise and authority to recognize technically sound
    standards promulgated by reputable and competent
    organizations such as ANSI.” 
    Id. at 551, ¶ 25
     (emphasis in
    the original).
    The 1985 RF Order used the ANSI standard as a
    “triggering mechanism for environmental assessment.” 
    Id. at 560, ¶ 51
    . Only applications for FCC authorization of
    radio and broadcast facilities not in compliance with the
    ANSI standard would require a thorough environmental-
    impact analysis, including the submission of a narrative
    environmental statement. 
    Id.
     at 560–61, ¶¶ 51–54. The 1985
    RF Order excluded from its requirements any “relatively low-
    powered communications systems” such as mobile devices,
    which had a low likelihood of causing exposure exceeding
    the ANSI standard. In re Responsibility of the Federal
    Communications Commission to Consider Biological Effects
    of Radiofrequency Radiation When Authorizing the Use of
    Radiofrequency Devices, 2 FCC Rcd. 2064, 2065, ¶¶ 14–15
    (Apr. 9, 1987); see 1985 RF Order, 100 F.C.C.2d at 561, ¶ 54.
    The ANSI standard, which the FCC adopted through its 1985
    RF Order, explicitly excluded “low power devices such as
    14                    COHEN V. APPLE
    hand-held, mobile, and marine radio transceivers” on the
    ground that while “[t]hese devices may emit localized fields
    exceeding the protection guides, [they] will result in a
    significantly lower rate of energy absorption than allowed for
    the whole body average.” ANSI, American National
    Standard Safety Levels with Respect to Human Exposure to
    Radio Frequency Electromagnetic Fields, 300 kHz to
    100 GHz 10 (1982).
    The FCC identified the “legal basis” for its 1985 RF
    Order as follows:
    This action is based on the obligations
    imposed on the [FCC] by NEPA, and is in
    furtherance of §§ 4(i), 4(j), and 303(r) of the
    Communications Act of 1934, as amended.
    These provisions permit the [FCC] to make
    rules and regulations not inconsistent with
    other existing laws, “as may be necessary in
    the execution of its functions,” and “to carry
    out the provisions of” the Communications
    Act.
    1985 RF Order, 100 F.C.C.2d at 565 (citations omitted) (first
    quoting 
    47 U.S.C. § 154
    (i); and then quoting 
    47 U.S.C. § 303
    (r)). The FCC identified two objectives in its 1985 RF
    Order: (1) “to clarify its policy with regard to potential
    hazards from RF radiation emitted by transmitting facilities
    that [it] license[s] or authorize[s];” and (2) “to comply with
    our legal obligations under NEPA.” 
    Id. at 564
    .
    In 1992, ANSI updated its guidelines, narrowing the
    scope of the exclusion of low-powered devices. In 1993, the
    FCC issued a notice of proposed rulemaking (“1993 NPRM”)
    COHEN V. APPLE                        15
    to adopt ANSI’s updated 1992 guidelines, noting that the
    narrower exclusion for low-powered devices was more
    protective than the broader exclusion in ANSI’s 1982
    guidelines.      In re Guidelines for Evaluating the
    Environmental Effects of Radiofrequency Radiation, 8 FCC
    Rcd. 2,849, 2,849, 2,851, ¶¶ 1, 14 (Apr. 8, 1993). The FCC
    identified the “legal basis” for its 1993 NPRM as follows:
    This action is a result of the [FCC’s] legal
    obligations under the NEPA to provide the
    means by which to evaluate [FCC] actions
    with respect to environmental significance,
    and it is in furtherance of Sections 4(i), 4(j),
    and 303(r) of the Communications Act of
    1934, as amended.
    
    Id. at 2,854, ¶ 31
    (C) (citations omitted).
    After issuance of the 1993 NPRM and while the FCC’s
    rulemaking was pending, Congress enacted the
    Telecommunication Act of 1996. The 1996 Act directed the
    FCC to “complete action . . . to prescribe and make effective
    rules regarding the environmental effects of radio frequency
    emissions” within 180 days after the effective date of the Act.
    1996 Act § 704(b), 110 Stat. at 152.
    In 1996, the FCC issued an order (“1996 RF Order”)
    adopting new RF radiation standards applicable to low-
    powered portable devices, including cell phones. In re
    Guidelines for Evaluating the Environmental Effects of
    Radiofrequency Radiation, 11 FCC Rcd. 15,123 (Aug. 1,
    1996). The 1996 RF Order noted that ANSI had adopted
    updated RF radiation guidelines in 1992, and that the updated
    ANSI standard was “more restrictive in the amount of
    16                     COHEN V. APPLE
    environmental RF exposure permitted.” Id. at 15,126, ¶ 8.
    The more protective 1992 ANSI standard provided two tiers
    of exposure criteria: (1) controlled environments, in which
    those exposed to RF radiation are aware of their potential for
    exposure (for example, as a condition of their employment),
    and (2) uncontrolled environments, in which exposed
    individuals have no knowledge or expectation that their RF
    radiation exposure may exceed permitted levels. Id.
    at 15,126, ¶ 8, 15,136, ¶ 35. The updated standard mandated
    a specific absorption rate (“SAR”) limit of 0.4 W/kg as
    averaged over the whole body and 8 W/kg for peak localized
    exposure (i.e., for a specific area of the body) for cell phones
    in controlled environments. Id. at 15,140, ¶ 46. It mandated
    an SAR limit of 0.08 W/kg for whole-body average exposure
    and 1.6 W/kg for peak localized exposure for cell phones in
    uncontrolled environments. Id.
    The 1996 RF Order adopted the distinction drawn by the
    1992 ANSI guidelines between controlled/uncontrolled
    environments. Id. at 15,139, ¶ 42. It also adopted the ANSI
    guidelines’ requirements for low-power devices whose
    radiating structure is in direct contact with or within
    20 centimeters of the human body under conditions of normal
    use (e.g., cell phones). Id. at 15,146–47, ¶¶ 62–63. Because
    most low-power, portable devices were intended for use by
    consumers rather than solely in the workplace, the FCC
    mandated a 1.6 W/kg maximum RF exposure for cell phones,
    and routine SAR evaluation “either by laboratory
    measurement techniques or by computational modeling, prior
    to equipment authorization or use.” Id. at 15,147, ¶ 65.
    The FCC’s 1996 RF Order satisfied FCC’s obligations
    under § 704(b) of the 1996 Act, which directed the FCC to
    “prescribe and make effective rules regarding the
    COHEN V. APPLE                         17
    environmental effects of radio frequency emissions” within
    180 days. 1996 Act § 704(b), 110 Stat. at 152. The FCC
    noted that the updated RF radiation guidelines “will protect
    the public and workers from exposure to potentially harmful
    RF fields.” 1996 RF Order, 11 FCC Rcd. at 15,124, ¶ 1. The
    FCC also noted that the guidelines “will be of benefit both to
    the public and to the telecommunications industry [because
    t]hey will provide assurance that recent scientific knowledge
    is taken into account regarding future decisions on approval
    of FCC-authorized facilities and equipment.” Id. at 15,184,
    ¶ 169. The FCC identified provisions of the 1934 Act, as
    amended, as its statutory authority to issue the 1996 RF
    Order. Id. at 15,185, ¶ 171.
    The regulatory scheme established by the FCC’s 1996 RF
    Order remains largely intact today. Under 
    47 C.F.R. § 2.1093
    (d)(1), “[a]pplications for equipment authorization of
    portable RF sources subject to routine environmental
    evaluation must contain a statement confirming compliance
    with the limits specified in § 1.1310 . . . .” In turn, 
    47 C.F.R. § 1.1310
    (c) provides: “The SAR limits for general
    population/uncontrolled exposure are 0.08 W/kg, as averaged
    over the whole body, and a peak spatial-average SAR of
    1.6 W/kg, averaged over any 1 gram of tissue.” If the FCC
    determines that a device, such as the iPhone, complies with
    its RF radiation guidelines (tested at maximum power and
    under more extreme conditions than normal use) and other
    technical standards, the agency issues a certification
    authorizing sale of the device. 
    47 C.F.R. § 2.907
    . If the
    device “would cause human exposure to levels of RF
    radiation in excess of the limits in § 1.1310,” the applicant for
    equipment authorization must prepare an environmental
    assessment. Id. § 1.1307(b)(1)(i)(C). The proposed device
    can still be approved for sale if the FCC determines that it
    18                    COHEN V. APPLE
    will not have a significant impact on the human environment.
    Id. § 1.1308(d). In practice, however, the FCC sees the RF
    radiation limits as a “de facto compliance requirement.”
    1996 RF Order, 11 FCC Rcd. at 15226. According to an
    amicus brief filed by the United States before the Supreme
    Court in 2011, cell phone manufacturers “have never
    attempted to obtain approval to sell non-compliant phones by
    submitting an [environmental assessment]” since the
    promulgation of the FCC’s RF radiation rules. Brief for the
    United States as Amicus Curiae at 19–20, Farina v. Nokia,

    at *19–20.
    In 2013, the FCC issued a notice of inquiry (“2013 Notice
    of Inquiry”) soliciting public comments about whether the
    1996 RF exposure limits should be reassessed. In re
    Reassessment of Federal Communications Commission
    Radiofrequency Exposure Limits and Policies, 28 FCC Rcd.
    3,498, 3,498, ¶ 1 (Mar. 29, 2013). The 2013 Notice of
    Inquiry affirmed the FCC’s previous view that it must strike
    a balance between public safety and the public’s access to
    new telecommunications services. The FCC explained:
    The [FCC] has a responsibility to provide a
    proper balance between the need to protect the
    public and workers from exposure to
    potentially harmful RF electromagnetic fields
    and the requirement that industry be allowed
    to provide telecommunications services to the
    public in the most efficient and practical
    manner possible. The intent of our exposure
    limits is to provide a cap that both protects the
    public based on scientific consensus and
    allows for efficient and practical
    COHEN V. APPLE                      19
    implementation of wireless services. The
    present [FCC] exposure limit is a “bright-line
    rule.” That is, so long as exposure levels are
    below a specified limit value, there is no
    requirement to further reduce exposure. The
    limit is readily justified when it is based on
    known adverse health effects having a
    well-defined threshold, and the limit includes
    prudent additional safety factors (e.g., setting
    the limit significantly below the threshold
    where known adverse health effects may
    begin to occur). Our current RF exposure
    guidelines are an example of such regulation,
    including a significant “safety” factor,
    whereby the exposure limits are set at a level
    on the order of 50 times below the level at
    which adverse biological effects have been
    observed in laboratory animals as a result of
    tissue heating resulting from RF exposure.

    In 2019, the FCC issued an order and resolution of notice
    of inquiry (“2019 RF Order”) that left intact its 1996 RF
    radiation guidelines, including for cell phones. In re
    Proposed Changes in the Commission’s Rules Regarding
    Human Exposure to Radiofrequency Electromagnetic Fields,
    34 FCC Rcd. 11,687, 11,688, ¶ 2 (Dec. 4, 2019); id at 11,696,
    ¶ 14. In Environmental Health Trust v. FCC, 
    9 F.4th 893
    (D.C. Cir. 2021), the D.C. Circuit granted in part a petition
    challenging the 2019 RF Order and remanded to the FCC for
    further proceedings. The D.C. Circuit held that the FCC
    “failed to provide a reasoned explanation for its
    20                     COHEN V. APPLE
    determination that its guidelines adequately protect against
    the harmful effects of exposure to radiofrequency radiation
    unrelated to cancer.”

    D. Factual and Procedural Background
    Plaintiffs-appellants Andrew Cohen and other individuals
    are iPhone users. Defendant-appellee Apple, Inc., is a
    California corporation. Apple designs, manufactures, and
    sells consumer electronic products, including the iPhone.
    In August 2019, the Chicago Tribune reported results of
    its independent investigation of RF radiation levels of popular
    cell phones sold in the United States. Sam Roe, We Tested
    Popular Cellphones for Radiofrequency Radiation. Now the
    FCC Is Investigating., Chi. Tribune, Aug. 21, 2019,
    https://www.chicagotribune.com/investigations/ct-cell-phone-
    radiation-testing-20190821-72qgu4nzlfda5kyuhteiieh4da-
    story.html. According to the report, RF radiation exposure
    from Apple’s iPhone 7 “measured over the legal safety limit
    and more than double” what Apple found from its own
    testing. 
    Id.
    Two days after publication of the Tribune’s report,
    plaintiffs filed a putative class action in the district court
    seeking to represent all iPhone users in the United States.
    Within a few weeks, a nearly identical complaint was filed in
    the district court on behalf of different named plaintiffs. The
    district court consolidated the two actions, and plaintiffs filed
    a consolidated amended class action complaint.
    The complaint alleged that RF radiation emitted by
    iPhones regularly exceeded the federal exposure limit. The
    complaint relied heavily on the Tribune’s testing of the RF
    COHEN V. APPLE                        21
    radiation emitted by iPhones, citing the Tribune’s report of
    data showing that RF radiation exposure to iPhone 7 models
    averaged 2.59 W/kg and 3.225 W/kg in two tests, both of
    which exceeded the federal exposure limit of 1.6 W/kg.
    Plaintiffs’ counsel also conducted their own testing, using the
    same lab the Tribune had used. They tested additional iPhone
    models, and they tested at a zero-millimeter distance to
    replicate use of the iPhone against the skin. According to
    their testing, RF radiation emitted by iPhone 7 models
    reached 3.6 W/kg at a 5-millimeter separation distance.
    Based on data obtained from this testing, the complaint
    alleged that Apple engaged in “deceptive and misleading”
    marketing by advertising iPhones as safe when used against
    the body (for example, by advertising the iPhone as “the
    Internet in your pocket” or showing people holding iPhones
    in their bare hands in commercials).
    The Tribune’s story prompted the FCC to conduct further
    testing of iPhones. In December 2019, the FCC published the
    results of its own testing. The FCC’s further testing
    measured RF radiation exposure from iPhones as well within
    the safety limits. The testing revealed no evidence of
    violation of the FCC’s technical standards.
    Plaintiffs’ complaint alleged eight claims against Apple
    under state tort and consumer-fraud laws: (1) Apple
    intentionally misrepresented the safety of iPhones despite
    knowing that their RF radiation exceeded federal limits;
    (2) Apple failed to exercise reasonable care in not warning
    plaintiffs about unsafe RF radiation emitted by iPhones;
    (3) Apple violated California’s Unfair Competition Law by
    failing to disclose that iPhones emitted RF radiation at unsafe
    levels or levels exceeding the federal limit; (4) Apple violated
    California’s Consumers Legal Remedies Act by failing to
    22                     COHEN V. APPLE
    disclose that iPhones emitted RF radiation at unsafe levels or
    levels exceeding the federal limit; (5) Apple violated
    California’s false advertising law by failing to disclose that
    iPhones emitted RF radiation at unsafe levels or levels
    exceeding the federal limit; (6) Apple violated various states’
    consumer protection acts due to its dissemination of
    deceptive and misleading advertising materials; (7) Apple
    was unjustly enriched because plaintiffs did not receive
    products as marketed by Apple; and (8) Apple breached its
    implied warranty that iPhones were safe for ordinary use.
    The complaint sought class certification, a finding of liability
    against Apple, the establishment of a medical monitoring
    fund under claims (1) and (2), money damages, appropriate
    injunctive relief, and attorney’s fees.
    On January 2, 2020, Apple moved to dismiss plaintiffs’
    complaint. Apple argued, inter alia, that plaintiffs lacked
    Article III standing and, assuming standing, that federal law
    preempted plaintiffs’ claims. Following a hearing, the district
    court found that Apple had presented matters outside of the
    pleadings. The district court converted Apple’s motion to
    dismiss into a motion for summary judgment.
    The district court invited the FCC to participate as amicus
    curiae. The FCC filed a statement of interest on April 13,
    2020, in which it made three main arguments. First, the FCC
    argued that “[t]o the extent that plaintiffs’ claims effectively
    challenge the adequacy or reasonableness of FCC testing
    procedures for assessing compliance with RF limits, the
    [district court] lacks jurisdiction” under 
    28 U.S.C. § 2342
    (1).
    Second, the FCC argued that “plaintiffs’ claims are
    preempted to the extent they suggest that RF emissions from
    cell phones certified by the FCC for sale in the United States
    are unsafe.” The FCC argued that the FCC’s regulations
    COHEN V. APPLE                        23
    reflected congressional expectation that “the FCC . . . use its
    expert judgment to balance different policy objectives,”
    including “between ‘adequate safeguards of the public health’
    and ‘speed[y] deployment of competitive wireless
    telecommunications services.’” The FCC contended that
    litigation such as plaintiffs’ “is especially disruptive to the
    FCC’s certification program because plaintiffs seek relief
    based on third-party testing that may have inaccurately
    measured the RF emissions of Apple’s iPhones.” Third, the
    FCC argued that the district court had no jurisdiction over
    plaintiffs’ state-law claims that Apple failed to disclose that
    iPhones emitted RF radiation at unsafe levels or levels
    exceeding the FCC’s RF limits. Even if the district court had
    jurisdiction, the FCC argued, federal law preempted those
    claims.
    In its statement of interest, the FCC asserted that Apple’s
    iPhone (including the iPhone 7, the iPhone X, and the iPhone
    XS) complied with federal RF radiation guidelines. The FCC
    stated that it had tested each iPhone model for the specific
    bands of operations investigated by the Chicago Tribune, and
    had found that the tested phones produced maximum
    measured exposure of 0.946 W/kg for the iPhone 7, 0.799
    W/kg for the iPhone X, and 1.35 W/kg for the iPhone
    XS—all well under the FCC’s permitted maximum of
    1.6 W/kg.
    In October 2020, the district court entered summary
    judgment for Apple. The district court held that the FCC
    promulgated substantive RF radiation regulations under the
    1934 Act rather than under NEPA. The district court found
    that the 1996 Act’s general savings clause, 
    47 U.S.C. § 253
    ,
    and § 601(c) of the 1996 Act did not change the normal
    operation of conflict-preemption analysis or limit the FCC’s
    24                     COHEN V. APPLE
    statutory authority to regulate RF radiation. The district court
    concluded that the FCC’s regulation of RF radiation, as part
    of its equipment-authorization regime, preempted plaintiffs’
    claims. In reaching this conclusion, the district court relied
    on Farina v. Nokia, Inc., 
    625 F.3d 97
    , 133–34 (3d Cir. 2010),
    in which the Third Circuit held that the FCC’s regulations
    preempted similar claims under state law.
    Plaintiffs timely appealed. On appeal, they concede that
    RF radiation emissions from Apple’s iPhone are at levels
    below the maximum permitted by FCC regulations. Their
    primary arguments on appeal are that (1) neither the 1934
    Act, 1996 Act, nor NEPA gives the FCC authority to preempt
    state law concerning cell-phone radiofrequency radiation, and
    (2) the FCC’s RF radiation regulations do not preempt
    state-law causes of action that are premised on maximum
    levels of RF radiation below the maximum level set by the
    FCC.
    II. Standard of Review
    We review a district court’s grant of summary judgment
    de novo. See Zetwick v. County of Yolo, 
    850 F.3d 436
    , 440
    (9th Cir. 2017). “Summary judgment is appropriate when,
    viewing the evidence in the light most favorable to the
    nonmoving party, there is no genuine dispute as to any
    material fact.” 
    Id.
     (citation omitted).
    III. Analysis
    A. Subject Matter Jurisdiction Under the Hobbs Act
    Under the Hobbs Act, federal courts of appeals (except
    the Federal Circuit) have “exclusive jurisdiction to enjoin, set
    COHEN V. APPLE                          25
    aside, suspend (in whole or in part), or to determine the
    validity of . . . all final orders of the [FCC] made reviewable
    by [
    47 U.S.C. § 402
    (a)].” 
    28 U.S.C. § 2342
    (1); see also
    
    47 U.S.C. § 402
    (a) (providing judicial review of FCC’s
    orders and decisions, including “[a]ny proceeding to enjoin,
    set aside, annul, or suspend any order of the [FCC]”). In
    addition to direct challenges to agency orders, the Hobbs Act
    grants exclusive jurisdiction to courts of appeals over suits
    against private parties that would require the court to enjoin,
    set aside, suspend, or determine the validity of a final FCC
    order. Wilson v. A.H. Belo Corp., 
    87 F.3d 393
    , 399–400 (9th
    Cir. 1996); see also Pub. Watchdogs v. S. Cal. Edison Co.,
    
    984 F.3d 744
    , 765 (9th Cir. 2020) (Nuclear Regulatory
    Commission order).
    Apple argues that the Hobbs Act broadly grants exclusive
    jurisdiction to courts of appeals over private suits that
    implicate the substance of agency determinations. Citing two
    of our cases, Apple argues that “the Hobbs Act divests district
    courts of jurisdiction to pass on any issue that would require
    them to decide whether they ‘agreed’ or ‘disagreed’ with a
    determination made in an FCC final order,” and that the
    district court therefore did not have jurisdiction over this
    case.
    We disagree. Neither case cited by Apple goes so far. In
    Wilson, 
    87 F.3d at 395
    , plaintiffs brought suit in district court
    against California television stations to recover payments for
    campaign advertisements that allegedly exceeded limits
    imposed by § 315(b) of the 1934 Act. The FCC had issued a
    declaratory ruling asserting its exclusive authority to
    adjudicate and enforce all claims under § 315(b). Id. We
    held that the Hobbs Act barred jurisdiction because the
    plaintiffs, in effect, had asked the district court to set aside or
    26                     COHEN V. APPLE
    determine the validity of the FCC’s declaratory ruling. Id. at
    400. Similarly, in Public Watchdogs, 984 F.3d at 765, the
    plaintiff brought state-law claims against utility companies,
    alleging mishandling of nuclear waste, and arguing that the
    Nuclear Regulatory Commission (“NRC”) had improperly
    granted a licensing amendment. We held that the Hobbs Act
    barred the plaintiff’s “veiled challenge” to the NRC license
    grant in the district court. Id. In both cases, plaintiffs’
    lawsuits in effect would have required the district court to set
    aside or determine the validity of an agency final order.
    By contrast, plaintiffs in this case do not challenge the
    validity of any of the FCC’s final orders, either directly or
    indirectly. The issue in this case is whether the FCC’s
    concededly valid orders have preemptive effect. A holding
    that the FCC orders do, or do not, preempt plaintiffs’ state-
    law claims has no effect on their validity.
    We therefore hold that the Hobbs Act does not deprive the
    district court of jurisdiction, and we reach the merits of the
    appeal.
    B. Preemption
    Plaintiffs argue on two grounds that their state-law claims
    are not preempted. First, they argue that the FCC
    promulgated its RF Orders under NEPA. They argue that
    because NEPA is a purely procedural statute with no
    preemptive force, regulations promulgated under NEPA do
    not preempt their state-law causes of action. Second, they
    argue that even if the FCC’s RF Orders were promulgated
    COHEN V. APPLE                        27
    under either, or both, of the twin Communications Acts, the
    savings clauses in those Acts preserve their state-law causes
    of action.
    We disagree with both grounds.
    1. NEPA
    We agree with plaintiffs that NEPA is a purely procedural
    statute and that it has no preemptive force. However, we do
    not agree with plaintiffs that the FCC’s RF Orders were
    promulgated under NEPA.
    The twin Communications Acts grant to the FCC broad
    regulatory powers over wireless communication devices. The
    1934 Act authorizes the FCC to: (1) “Regulate the kind of
    apparatus to be used with respect to its external effects and
    the purity and sharpness of the emissions,” 
    47 U.S.C. § 303
    (e); (2) “Make such rules and regulations and prescribe
    such restrictions and conditions, not inconsistent with law, as
    may be necessary to carry out the provisions of [the
    Communications Acts],” 
    id.
     § 303(r); and (3) “[P]erform any
    and all acts, make such rules and regulations, and issue such
    orders, not inconsistent with this chapter, as may be necessary
    in the execution of its functions,” id. § 154(i).
    The 1996 Act directed the FCC to complete rulemaking
    for RF radiation that had already been initiated under the
    1934 Act. Section 704(b) of the 1996 Act provides: “Within
    180 days after the enactment of this Act, the [FCC] shall
    complete action in ET Docket 93-62 to prescribe and make
    effective rules regarding the environmental effects of radio
    frequency emissions.” 1996 Act § 704(b), 110 Stat. at 152.
    Section 704(b) does not itself grant rulemaking authority.
    28                     COHEN V. APPLE
    Rather, it requires the FCC to complete its preexisting
    rulemaking proceeding initiated in the 1993 NPRM under the
    authority of the 1934 Act. See Farina, 
    625 F.3d at
    128 &
    n.28.
    The FCC has been consistent in stating that its authority
    to regulate RF radiation-emitting communication devices
    comes from the 1934 Act. The FCC wrote in the 1982
    NPRM that led to its 1985 RF Order, “The action proposed
    is . . . in furtherance of §§ 4(i) and 303(r) of the
    Communications Act of 1934 . . . , which permits the [FCC]
    to make rules and regulations . . . as may be necessary in the
    execution of its functions.” 1982 NPRM, 89 F.C.C.2d at 255.
    It wrote in connection with the 1985 RF Order itself, “This
    action is . . . in furtherance of §§ 4(i), 4(j), and 303(r) of the
    Communications Act of 1934[.]” 1985 RF Order, 100
    F.C.C.2d at 565. It wrote in the 1993 NPRM that led to its
    1996 RF Order, “This action is . . . in furtherance of Sections
    4(i), 4(j), and 303(r) of the Communications Act of 1934[.]”
    1993 NPRM, 8 FCC Rcd. at 2854. It wrote in its 2019 RF
    Order, “The [FCC’s] authority to adopt and enforce RF
    exposure limits pursuant to the Communications Act . . . is
    well established.” 2019 RF Order, 34 FCC Rcd. at 11,689
    n.5.
    NEPA, by contrast, grants no affirmative regulatory
    powers over wireless communications. It is a procedural
    statute designed to ensure that federal actions, including
    regulatory actions, are reviewed for their environmental
    consequences. See 
    42 U.S.C. § 4332
    . The FCC’s 1985, 1996
    and 2019 RF Orders were not authorized by NEPA. Rather,
    they were constrained by NEPA. Several of the FCC’s
    statements reflect this understanding of NEPA. For example,
    the FCC wrote in its 1985 RF Order, “This action is based on
    COHEN V. APPLE                         29
    the obligations imposed on the [FCC] by NEPA[.]” 1985 RF
    Order, 100 F.C.C.2d at 565. It wrote in its 1996 RF Order
    that it issued the order “to fulfill [its] responsibilities under
    NEPA.” 1996 RF Order, 11 FCC Rcd. at 15,183. It wrote in
    its 2019 RF Order, “The Commission’s authority to adopt and
    enforce RF exposure limits . . . consistent with NEPA is well
    established.” 2019 RF Order, 34 FCC Rcd. at 11,689 n.5.
    We therefore reject plaintiffs’ argument that the FCC’s
    RF Orders were promulgated under NEPA.
    2. The Twin Communications Acts
    Alternatively, plaintiffs argue that neither the 1934 Act
    nor the 1996 Act preempts their state-law claims. They make
    essentially two arguments. First, they argue that the 1934 Act
    does not provide authority to the FCC to promulgate
    regulations that preempt their state-law claims. Second, they
    argue that reading the 1934 and 1996 Acts together “makes
    clear that Congress did not authorize the FCC’s regulations
    to displace state law here.” We take each argument in turn.
    a. Authority under the 1934 Act
    Plaintiffs argue that the 1934 Act does not authorize
    preemption by regulations promulgated under the Act, and
    that its state-law causes of action are not preempted by the
    FCC’s orders. We disagree.
    “The Supremacy Clause provides the constitutional
    foundation for federal authority to preempt state law.”
    Beaver v. Tarsadia Hotels, 
    816 F.3d 1170
    , 1178 (9th Cir.
    2016) (citing U.S. Const. art. VI, cl. 2; Kurns v. R.R. Friction
    Prods. Corp., 
    565 U.S. 625
    , 630 (2012)). “Preemption of
    30                    COHEN V. APPLE
    state law, by operation of the Supremacy Clause, can occur in
    one of several ways: express, field, or conflict preemption.”
    
    Id.
     (citing Kurns, 
    565 U.S. at
    630–31). Absent express
    congressional preemption, federal law preempts state law
    “when the scope of a [federal] statute indicates that Congress
    intended federal law to occupy a field exclusively,” Kurns,
    
    565 U.S. at 630
     (alteration in original) (quoting Freightliner
    Corp. v. Myrick, 
    514 U.S. 280
    , 287 (1995)), or where “the
    state law ‘stands as an obstacle to the accomplishment and
    execution of the full purposes and objectives of Congress,’”
    Beaver, 816 F.3d at 1179 (quoting Crosby v. Nat’l Foreign
    Trade Council, 
    530 U.S. 363
    , 372–73 (2000)). Our
    “preemption analysis is driven by the presumption that ‘the
    historic police powers of the States were not to be superseded
    by the Federal Act unless that was the clear and manifest
    purpose of Congress.’” 
    Id.
     (quoting Wyeth v. Levine,
    
    555 U.S. 555
    , 565 (2009)).
    A federal statute need not specify its preemptive force in
    order for the statute to have such force. The Supreme Court
    has stated, plainly and repeatedly: “A pre-emptive
    regulation’s force does not depend on express congressional
    authorization to displace state law[.]” Fid. Fed. Sav. & Loan
    Ass’n v. de la Cuesta, 
    458 U.S. 141
    , 154 (1982); see also City
    of New York v. FCC, 
    486 U.S. 57
    , 64 (1988). While plaintiffs
    protest that “Apple dusts off two decades-old cases” (both de
    la Cuesta and City of New York were decided in the 1980s),
    the Supreme Court has never overruled either case, and they
    remain good law. We have cited them as providing the
    standard governing agency preemption. See MetroPCS Cal.,
    LLC v. Picker, 
    970 F.3d 1106
    , 1117 (9th Cir. 2020);
    Barrientos v. 1801–1825 Morton LLC, 
    583 F.3d 1197
    , 1208
    (9th Cir. 2009) (specifically citing de la Cuesta, 
    458 U.S. at 154
    , for the proposition that “[a] pre-emptive regulation’s
    COHEN V. APPLE                       31
    force does not depend on express congressional authorization
    to displace state law”). We therefore conclude that Congress
    need not expressly delegate preemptive authority to the FCC
    for its regulations to preempt state law.
    “Along with Congress, ‘a federal agency acting within the
    scope of its congressionally delegated authority may pre-empt
    state regulation.’” Barrientos, 
    583 F.3d at 1208
     (quoting City
    of New York, 
    486 U.S. at
    63–64). First, for a regulation to
    have preemptive force, it must fall “within the scope of the
    [federal agency’s] delegated authority,” 
    id.
     at 
    583 F.3d at 1208
     (alteration in original) (quoting de la Cuesta,
    
    458 U.S. at 154
    ), or, in other words, it must be “statutorily
    authorized,” City of New York, 
    486 U.S. at 64
    . Second, the
    agency must have “meant to pre-empt” state law. MetroPCS,
    970 F.3d at 1117 (quoting Barrientos, 
    583 F.3d at 1208
    ).
    “Where, as here, we consider whether a federal agency has
    preempted state regulation, we do not focus on Congress’s
    ‘intent to supersede state law’ but instead ask ‘whether [the
    federal agency] meant to pre-empt [the state law].’” 
    Id.
    (quoting Barrientos, 
    583 F.3d at 1208
    ).
    Importantly, the intent to pre-empt need not be express.
    Geier v. Am. Honda Motor Co., 
    529 U.S. 861
    , 884–85 (2000).
    Under the doctrine of implied conflict preemption, “[t]he
    statutorily authorized regulations of an agency will pre-empt
    any state or local law that conflicts with such regulations or
    frustrates the purposes thereof.” City of New York, 
    486 U.S. at 63
    . In other words, it must be either “impossible to comply
    with both state and federal requirements,” or the state law
    must stand “as an obstacle to the accomplishment and
    execution of the full purposes and objectives of [the federal
    agency].” MetroPCS, 970 F.3d at 1118. State law may pose
    such an obstacle when it disturbs a balance the federal
    32                     COHEN V. APPLE
    regulation has struck between “conflicting policies that were
    committed to the agency’s care by the statute.” Barrientos,
    
    583 F.3d at 1208
     (alteration in original) (quoting City of New
    York, 
    486 U.S. at 64
    ). The balance struck by the federal
    agency should not be disturbed “unless it appears from the
    statute or its legislative history that [the balance] is not one
    that Congress would have sanctioned.” City of New York,
    
    486 U.S. at 64
     (quoting United States v. Shimer, 
    367 U.S. 374
    , 383 (1961)).
    As an initial matter, the plaintiffs argue that because
    matters of health and safety, such as the biological effects of
    cell phone RF radiation, fall within states’ historic police
    powers, the presumption against preemption applies in this
    case. We assume, without deciding, that the presumption
    applies. Nevertheless, the presumption is overcome because
    the conflict between the FCC’s RF radiation regulations and
    plaintiffs’ state law claims poses a sufficient obstacle to the
    full accomplishment of the FCC’s objectives. See Crosby v.
    Nat’l Foreign Trade Council, 
    530 U.S. 363
    , 374 n.8 (2000).
    As discussed above, the FCC’s RF radiation regulations
    were promulgated pursuant to §§ 4(i), 4(j) and 303(r) of the
    1934 Act. The regulations thus fall within the scope of the
    agency’s delegated authority under the 1934 Act. The 1934
    Act grants broad authority to the FCC to promulgate
    regulations that strike a balance among overlapping and
    potentially conflicting policies. These policies include the
    promotion of “a rapid, efficient, [n]ation-wide, and world-
    wide . . . communication service,” the promotion of “safety
    of life and property through the use of wire and radio
    communications,” “national defense,” and the encouragement
    of “provision of new technologies and services to the public.”
    
    47 U.S.C. §§ 151
    , 157(a). The FCC’s RF radiation
    COHEN V. APPLE                        33
    regulations, as applied to cell phones, were intended to strike
    such a balance.
    In its 1979 Notice of Inquiry, the FCC noted that, in
    fulfilling its statutory mandate under the 1934 Act, “[a]
    balance must be achieved between serving the public interest
    by fulfilling its needs for communications services and
    adequately protecting the populace against potentially adverse
    biological effects that may be attributable to excessive RF
    radiation.” 1979 Notice of Inquiry, 72 F.C.C.2d at 489, ¶ 17.
    The 2013 Notice of Inquiry affirmed the FCC’s previous
    view that it must strike a balance between public safety and
    the public’s access to new telecommunications services. See
    2013 Notice of Inquiry, 28 FCC Rcd. at 3,582, ¶ 236.
    Plaintiffs’ state-law claims would disrupt the balance
    struck by the FCC. In an analogous case, the Third Circuit
    has explained:
    The reason why state law conflicts with
    federal law in these balancing situations is
    plain. When Congress charges an agency
    with balancing competing objectives, it
    intends the agency to use its reasoned
    judgment to weigh the relevant considerations
    and determine how best to prioritize between
    these objectives. Allowing state law to
    impose a different standard permits a re-
    balancing of those considerations. A state-
    law standard that is more protective of one
    34                     COHEN V. APPLE
    objective may result in a standard that is less
    protective of others.
    Farina, 
    625 F.3d at 123
    . The same reasoning applies in this
    case. The FCC’s adoption of specific RF radiation limits for
    cell phones is the result of the agency’s striking a balance
    between the conflicting policies of public safety and the
    public’s access to telecommunications technologies.
    The savings clause in § 414 of the 1934 Act does not help
    plaintiffs. We quoted it above. For the convenience of the
    reader, here it is again: “Nothing in this chapter contained
    shall in any way abridge or alter the remedies now existing at
    common law or by statute, but the provisions of this chapter
    are in addition to such remedies.” 
    47 U.S.C. § 414
    .
    On appeal, plaintiffs do not press the allegations in their
    complaint that Apple’s iPhones emit RF radiation at levels
    above the maximum permitted by FCC regulations. For
    purposes of appeal, they concede that Apple’s iPhones
    comply with the FCC’s RF radiation regulations. They write,
    “On appeal, [plaintiffs] pursue only their claims that Apple
    devices are unsafe ‘in spite of’ compliance with federal
    standards and that Apple fails to disclose their dangers.”
    Plaintiffs’ concession that Apple’s iPhone complies with
    emission levels prescribed by the FCC is fatal to their appeal.
    If plaintiffs were to press the allegations in the complaint
    that Apple’s iPhones exceeded the maximum RF radiation
    levels permitted by the FCC, and were to argue that the state-
    law remedies they seek were premised on Apple’s violations
    of the FCC’s RF radiation standards, this would be a different
    appeal, and the savings clause might have some force. Cf.
    Stengel v. Medtronic Inc., 
    704 F.3d 1224
    , 1233 (9th Cir.
    COHEN V. APPLE                        35
    2013) (en banc). However, this is not their argument.
    Plaintiffs’ argument on appeal is that state-law causes of
    action premised on RF radiation emission standards more
    protective than those prescribed by the FCC are not
    preempted.
    In Geier v. American Honda Motor Co., 
    529 U.S. 861
    (2000), the Supreme Court wrote that it “has repeatedly
    ‘decline[d] to give broad effect to saving clauses where doing
    so would upset the careful regulatory scheme established by
    federal law.’” 
    Id. at 870
     (quoting United States v. Locke,
    
    529 U.S. 89
    , 106–107 (2000)). Consistently with Geier, we
    have held that § 414, the savings clause of the 1934 Act,
    preserves only those rights not inconsistent with the statutory
    requirements. Telesaurus VPC, LLC v. Power, 
    623 F.3d 998
    ,
    1010 (9th Cir. 2010). Section 414 cannot be read expansively
    to “abrogate the very federal regulation of mobile telephone
    providers that the [1934 Act] intended to create.” 
    Id. at 1011
    (quoting Bastien v. AT&T Wireless Servs., Inc., 
    205 F.3d 983
    ,
    987 (7th Cir. 2000)). “Said otherwise, we infer that Congress
    did not intend the saving provisions in a federal law to be
    interpreted in a way that causes the federal law ‘to defeat its
    own objectives,’” including those implemented by federal
    regulations. In re Volkswagen “Clean Diesel” Mktg., Sales
    Pracs., & Prods. Liab. Litig., 
    959 F.3d 1201
    , 1214 (9th Cir.
    2020) (quoting Geier, 
    529 U.S. at 872
    ).
    In American Telephone & Telegraph Co. v. Central Office
    Telephone, Inc., 
    524 U.S. 214
     (1998), the Supreme Court
    refused to construe § 414 as saving state-law tort and breach
    of contract claims from preemption under the 1934 Act’s
    filed rate doctrine. The Court wrote:
    36                    COHEN V. APPLE
    A claim for services that . . . directly conflict
    with the tariff—the basis for both the tort and
    contract claims here—cannot be “saved”
    under § 414. “Th[e saving] clause . . . cannot
    in reason be construed as continuing in
    [customers] a common law right, the
    continued existence of which would be
    absolutely inconsistent with the provisions of
    the act. In other words, the act cannot be held
    to destroy itself.”
    Id. at 227–28 (alteration and omission in original) (quoting
    Tex. & Pac. Ry. Co. v. Abilene Cotton Oil Co., 
    204 U.S. 426
    ,
    446 (1907)).
    So too here. The 1934 Act authorizes the FCC to balance
    the overlapping and potentially competing factors in setting
    safe and uniform limits for RF radiation from cell phones.
    Allowing state tort law to prescribe lower levels of RF
    radiation than the levels prescribed by the FCC would
    interfere with the nationwide uniformity of regulation that is
    the aim of the Act, and would render the FCC’s statutorily
    mandated balancing essentially meaningless. If state law
    were allowed to prescribe such levels, it would “stand[] as an
    obstacle to the accomplishment and execution of the full
    purposes and objectives of Congress.” Beaver, 816 F.3d
    at 1179 (quoting Crosby, 
    530 U.S. at
    372–73).
    We therefore hold that the FCC’s regulations under the
    1934 Act, setting upper limits on the levels of permitted RF
    radiation, preempt state laws that impose liability premised
    on levels of radiation below the limits set by the FCC.
    COHEN V. APPLE                       37
    b. Reading the 1934 and 1996 Acts Together
    Plaintiffs argue that the preemptive scope of the FCC’s
    RF radiation regulations cannot be determined solely by
    consulting the 1934 Act. They argue that the 1934 and 1996
    Acts must be read together. They write in their brief that it
    was in the 1996 Act “that Congress carefully delineated the
    limited scope of the FCC’s preemptive authority.” We
    disagree. We hold that the scope of preemption of the FCC’s
    RF radiation regulations is controlled by the 1934 Act, and
    that the preemption provisions of the 1996 Act are irrelevant.
    As discussed in detail above, the FCC’s RF radiation
    regulations were promulgated under §§ 4(i), 4(j), and 303(r)
    of the 1934 Act. The 1996 Act directed the FCC to complete
    within 180 days a pending rulemaking proceeding with
    respect to RF radiation for cell phones. 1996 Act § 704(b),
    110 Stat. at 152. But the 1996 Act did not provide the
    underlying authority for adopting the RF radiation
    regulations. It merely directed the FCC to complete quickly
    the pending rulemaking proceeding under the 1934 Act.
    As also discussed above, there are two preemption
    provisions in the 1996 Act. First, there is a narrowly focused
    savings clause. Section 332(c)(7)(A) of the 1996 Act
    provides, “[N]othing in this chapter shall limit or affect the
    authority of a State or local government or instrumentality
    thereof over decisions regarding the placement, construction,
    and modification of personal wireless service facilities.”
    
    47 U.S.C. § 332
    (c)(7)(A). This provision protects the
    placement, construction, and modification of state and local
    “facilities,” such as cell phone towers, from preemption under
    the 1996 Act. It has nothing to do with RF radiation
    emissions from cell phones.
    38                    COHEN V. APPLE
    Second, there is a general savings clause. Section 601 of
    the 1996 Act provides: “This Act and the amendments made
    by this Act shall not be construed to modify, impair, or
    supersede Federal, State, or local law unless expressly so
    provided in such Act or amendments.” 1996 Act § 601(c)(1),
    110 Stat. at 143 (emphasis added). By its plain terms, this
    provision applies only to “this Act”—that is, to the 1996 Act.
    It does not apply to the 1934 Act.
    Because § 332(c)(7)(A) applies only to “facilities,” and
    § 601(c)(1) applies only to the 1996 Act, the preemption
    provisions of the 1996 Act do not affect the preemptive scope
    of the FCC’s RF radiation regulations under the 1934 Act.
    Conclusion
    We hold that the Hobbs Act does not deprive the district
    court of jurisdiction in this case. We hold, further, that the
    FCC’s regulations of the RF radiation of cell phones,
    promulgated under the 1934 Act, preempt plaintiffs’ state-law
    claims as they are presented to us on appeal.
    AFFIRMED.
