    WILKINSON, Circuit Judge:
    Power Fuels, LLC, petitions for review of a final order of
    the    Federal     Mine    Safety    and        Health      Review    Commission.        Power
    Fuels operates a facility that receives, blends, stores, and
    delivers     coal    to    meet     the    specifications             of    a    power   plant
    located across the road. The Department of Labor’s Mine Safety
    and   Health     Administration       (“MSHA”)             asserted   jurisdiction          over
    the facility under the Federal Mine Safety and Health Act of
    1977 (“Mine Act”).
    The Mine Act covers operators of a “coal or other mine,”
    including facilities engaged in the “work of preparing coal.” 30
    U.S.C. § 802(h)(1)(C), (i). Power Fuels challenged the Secretary
    of Labor’s assignment of jurisdiction to MSHA, rather than to
    the nonspecialized Occupational Safety and Health Administration
    (“OSHA”). We hold that the Secretary permissibly concluded that
    a facility that blends coal for a nearby power plant was subject
    to    the   Mine    Act.   Because        the       Mine    Act   covers        this   kind   of
    activity,      MSHA’s      assertion       of        jurisdiction          was    proper.     We
    therefore deny the petition for review.
    I.
    The parties do not dispute the facts underlying this case.
    In any event, we will sustain the Commission’s factual findings
    3
    so long as they are “supported by substantial evidence on the
    record considered as a whole.” 30 U.S.C. § 816(a)(1).
    A.
    Power Fuels owns and operates a coal-blending terminal in
    Wise    County,     Virginia.     At    this      site,    Power     Fuels    receives,
    tests,     weighs,     samples,      mixes,       blends,     stores,    loads,     and
    transports coal for its customer, Virginia Electric and Power
    Company,    doing    business      as       Dominion   Virginia      Power.    Dominion
    runs   a   power    plant,   the     Virginia       City    Hybrid    Energy   Center,
    which produces electricity from coal and biomass. Power Fuels’
    blending terminal and Dominion’s plant are situated on adjoining
    properties.
    Power   Fuels    works   as      a    contractor      for   Dominion    under   a
    formal agreement. The products provided by Power Fuels include
    coal and coal refuse, or “gob.” Power Fuels mixes an estimated
    average of eight thousand tons of coal per day for Dominion at
    the    blending    terminal,    and         the   facility    stores    an    eight-day
    supply of fuel for Dominion’s use. Dominion owns all the coal
    that Power Fuels prepares. Approximately eighty percent of the
    fuel consumed at Dominion’s plant passes through Power Fuels’
    blending terminal, while the remaining twenty percent comes to
    the plant from other locations.
    4
    Power     Fuels    blends      the     coal       according         to     the     precise
    specifications provided daily by Dominion to ensure a proper
    reaction at the power plant. After the coal arrives, Power Fuels
    samples it and moves the material into separate piles, and it
    then   uses      equipment       at   the     facility          to    blend     the      coal    as
    directed by Dominion. Dominion’s orders specify, for example,
    the number of buckets of each material to be used in the desired
    blend, as well as moisture, ash, sulfur, and BTU content. Under
    the      companies’        agreement,          Power            Fuels       may         recommend
    modifications of Dominion’s order, but it must blend the coal as
    instructed unless Dominion decides to change the specifications
    for that day. Power Fuels then tests the product. Based on the
    test results, Dominion may alter the order, in which case Power
    Fuels blends and tests the pile again until it meets Dominion’s
    needs. The facility does not extract, crush, size, screen, or
    wash coal during this process. Finally, trucks transport the
    finished products across the road, from the blending terminal to
    Dominion’s power plant.
    B.
    Dominion’s        plant    and    Power          Fuels’       terminal      both    began
    operations in 2011. The following year, an inspector from MSHA
    noticed    trucks     delivering        coal       to    the     Power     Fuels      site.     The
    agency     was    unaware        at     the    time        of        any   coal-preparation
    5
    facilities       operating     there.     An       investigator      from    MSHA     then
    visited the site and observed that Power Fuels was blending,
    storing, and loading coal for the power plant across the road.
    Following a review by MSHA and the Department of Labor’s Office
    of the Solicitor, the Secretary determined that the blending
    terminal was subject to MSHA’s jurisdiction.
    Once      MSHA     asserted        jurisdiction,         the     agency        began
    performing       inspections      of     the       facility.   In    April    2013,     an
    inspector issued three citations to Power Fuels for violations
    of   MSHA    standards    involving        the      trucks’    braking      systems    and
    warning     devices.     See   30      C.F.R.      §   77.410(c),    77.1605(b).       The
    agency assessed a civil penalty of one hundred dollars for each
    citation.       MSHA   later    imposed        additional      citations      on    Power
    Fuels,    but    the   contests     of    those        citations    have    been    stayed
    pending the outcome of this appeal.
    Power Fuels contested the three initial citations on the
    ground that it was not the operator of a mine for the purposes
    of the Mine Act, and that MSHA consequently lacked jurisdiction.
    In November 2013, an administrative law judge for the Federal
    Mine Safety and Health Review Commission held an evidentiary
    hearing. In a March 2014 decision, the ALJ concluded that Power
    Fuels was engaged in the “work of preparing the coal” under the
    Mine Act. 30 U.S.C. § 802(h)(1)(C), (i). The ALJ took particular
    note of the fact that “the testing, blending, and re-blending as
    6
    necessary, are directly accomplished in order to [e]nsure and
    maintain     the    consistent        quality          of    the    coal     pursuant       to
    Dominion’s        quality       specifications.”             J.A.      333.        The     ALJ
    accordingly       ruled     that     MSHA’s       jurisdictional            assertion       was
    proper,     and     he     affirmed        the        citations       and     accompanying
    penalties.
    Power Fuels filed a petition for discretionary review with
    the Commission. The Commission declined to grant review, and
    consequently the ALJ’s decision became the final order of the
    Commission. See 30 U.S.C. § 823(d)(1). Power Fuels now petitions
    for review in this court. See 
    id. § 816(a).
    II.
    A.
    The Mine Act specifically protects the safety and health of
    individuals       who    work   in   a     “coal      or    other     mine.”    30       U.S.C.
    § 802(h)(1)(C); see 
    id. § 801.
    But even before MSHA asserted
    jurisdiction under the Mine Act, Power Fuels’ blending terminal
    was   not    beyond       the      reach    of        federal      safety      and       health
    regulations.       The    Occupational       Safety         and    Health    Act     of   1970
    (“OSH Act”) provides a statutory baseline for “assur[ing] so far
    as possible every working man and woman in the Nation safe and
    healthful    working      conditions.”           29   U.S.C.       § 651(b).    This       far-
    reaching    enactment       mandates       workplaces         “free    from     recognized
    7
    hazards.”        
    Id. § 654(a)(1).
            Where       Congress        has     enacted      an
    industry-specific          statute      conferring          authority          over    working
    conditions       on    another   agency,       however,       the    OSH       Act    does    not
    apply.      29   U.S.C.     § 653(b)(1).           The     Mine   Act,      which      governs
    occupational safety and health at “[e]ach coal or other mine,”
    is such a statute. 30 U.S.C. § 803.
    In    practice,         then,     the       regulatory        dynamic          involves
    displacement: MSHA may “exercise[] its statutory authority under
    the Mine Act in such a way as to preempt OSHA’s regulatory
    jurisdiction under the OSH Act.” United Energy Servs., Inc. v.
    Fed. Mine Safety & Health Admin., 
    35 F.3d 971
    , 977 (4th Cir.
    1994). The OSH Act is “comprehensive,” Martin v. Occupational
    Safety & Health Review Comm’n, 
    499 U.S. 144
    , 147 (1991), but it
    also    affords        space   for     specialized         regulatory          schemes.       The
    Secretary of Labor administers both the Mine Act and the OSH Act
    and determines initially whether a workplace falls under the
    jurisdiction       of    MSHA,   rather      than        OSHA.    See,    e.g.,       Sec’y    of
    Labor v. Nat’l Cement Co. of Cal., 
    494 F.3d 1066
    , 1073 (D.C.
    Cir. 2007).
    The regulatory systems administered by MSHA and OSHA share
    many     similarities,         but     the     differences          --     in    scope        and
    enforcement -- may hold significant implications for an employer
    and its employees. For example, although OSHA has established
    extensive        workplace       standards           for     toxic         and        hazardous
    8
    substances,   see    29   C.F.R.   pt.       1910,    subpts.    H,     Z,    MSHA’s
    regulations are specifically tailored to the dangers that arise
    from handling coal, such as exposure to coal dust and other
    airborne contaminants, see 30 C.F.R. pt. 71. The Mine Act also
    provides the Secretary with an array of enforcement mechanisms,
    such as inspections, investigations, recordkeeping, citations,
    and orders, that are particularized to the industry’s hazards.
    See 30 U.S.C. §§ 813, 814. The Secretary may need to draw on
    “historical familiarity and policymaking expertise” to determine
    which agency’s framework is appropriate for a given workplace.
    
    Martin, 499 U.S. at 153
    .
    B.
    With the Mine Act, Congress fashioned a law that is not
    only tailored to a specific industry, but also comprehensive in
    its coverage. The force of the statute is evident even from
    Congress’s    preliminary     declarations.               30   U.S.C.        § 801(c)
    (identifying “an urgent need to provide more effective means and
    measures for improving the working conditions and practices in
    the Nation’s coal or other mines in order to prevent death and
    serious   physical   harm,   and   in       order    to    prevent    occupational
    diseases originating in such mines”). Congress also expressed
    particular solicitude for the individuals who are continually
    exposed to the hazards of mining. 
    Id. § 801(a)
    (announcing that
    9
    “the first priority and concern of all in the coal or other
    mining   industry   must   be   the   health   and   safety   of   its   most
    precious resource -- the miner”). And Congress indicated that,
    even as new mandatory standards were developed, 
    id. § 801(g)(1)-
    (2), operators would need to work with their employees to keep
    these workplaces safe, 
    id. § 801(e)
    (stating that “the operators
    of such mines with the assistance of the miners have the primary
    responsibility to prevent the existence of such conditions and
    practices in such mines”).
    The Mine Act is also a broadly written statute. “Each coal
    or other mine” is subject to the coverage of the Mine Act, 
    id. § 803,
    and that term carries an expansive statutory meaning, see
    
    id. § 802(h)(1).
    As relevant to this case, the Mine Act provides
    that the term “coal or other mine” encompasses:
    lands, excavations, underground passageways, shafts,
    slopes, tunnels and workings, structures, facilities,
    equipment,   machines,   tools,   or   other    property
    including impoundments, retention dams, and tailings
    ponds, on the surface or underground, used in, or to
    be used in, or resulting from, the work of extracting
    such minerals from their natural deposits in nonliquid
    form, or if in liquid form, with workers underground,
    or used in, or to be used in, the milling of such
    minerals, or the work of preparing coal or other
    minerals,   and   includes  custom   coal    preparation
    facilities.
    
    Id. § 802(h)(1)(C)
    (emphasis added). The definition of the “work
    of preparing the coal,” in turn, includes a lengthy list of
    activities, as well as a flexible final phrase: “the breaking,
    10
    crushing,        sizing,     cleaning,           washing,      drying,    mixing,     storing,
    and loading of bituminous coal, lignite, or anthracite, and such
    other work of preparing such coal as is usually done by the
    operator of the coal mine.” 
    Id. § 802(i).
    As the statutory text makes clear, the coverage of the Mine
    Act   is    not     limited       to   extractive            activities      only.    The    Act,
    crucially,         extends    to       a    variety       of    activities      involved       in
    preparing          coal.     The        statute’s            jurisdictional          reach     is
    deliberately        broad,     and         the    concomitant         definitions      are    not
    rigid.      As     the     Senate          Committee         Report    stated,       “what    is
    considered to be a mine and to be regulated under this Act”
    ought to “be given the broadest possibl[e] interpretation,” and
    any “doubts” about jurisdiction ought to “be resolved in favor
    of inclusion of a facility within the coverage of the Act.”
    S. Rep. No. 95-181, at 14 (1977), reprinted in 1977 U.S.C.C.A.N.
    3401,      3414.     In    sum,    Congress            concluded      that    the    workplace
    hazards associated with mining coal or other minerals required
    safety      and     health        measures         specifically          tailored      to     the
    industry.        Congress     thus         produced      a     comprehensive        statute    to
    ensure that the people who face such dangers -- even workers
    involved     not     in    extraction            but    in     preparation     --     would    be
    protected.
    11
    III.
    Power    Fuels    contends        that       MSHA’s   jurisdiction          under   the
    Mine    Act    does     not      reach    the       company’s      blending        terminal.
    According to Power Fuels, the facility simply blends and stores
    coal as directed by a utility, and it does not undertake the
    type of work usually performed by the operator of a coal mine.
    But the Mine Act plainly says that a covered coal mine may
    engage in the “work of preparing coal,” 30 U.S.C. § 802(h)(1)(C)
    -- such as “mixing,” “storing,” and “loading” coal, as well as
    other comparable activities, 
    id. § 802(i).
    The Act even states
    that    coal      mines       may       include          “custom      coal     preparation
    facilities.” 
    Id. § 802(h)(1)(C)
    . Whether this question is viewed
    through   the    prism      of    the    kind       of   facility     that    Power      Fuels
    operates or the kind of work that Power Fuels performs, it is
    clear that Power Fuels falls within the coverage of the Mine
    Act.
    A.
    Power Fuels’ blending terminal is the type of facility that
    is   subject    to    the     Mine      Act.    The      Mine   Act      enables    MSHA   to
    regulate “[e]ach coal or other mine,” “each operator of such
    mine,” and “every miner in such mine.” 30 U.S.C. § 803; see 
    id. § 802(d),
         (g),   (h).    The    statutory           meaning    of    “coal     or   other
    mine”   expressly       embraces        facilities        engaged     in     the   “work   of
    12
    preparing coal.” 
    Id. § 802(h)(1)(C)
    . The coal mines covered by
    the    Act     also       specifically         include      “custom       coal   preparation
    facilities.”          
    Id. Power Fuels’
          blending       terminal     is   such    a
    facility.
    At     the    blending      terminal,         Power       Fuels    receives,    tests,
    weighs, samples, mixes, blends, stores, loads, and transports
    coal to meet the specifications of its customer, Dominion. With
    some eight thousand tons of coal mixed each day and eight days
    of    fuel    stored        onsite,     this    is    not    a    small    operation.     Coal
    preparation logically involves an anticipated use -- preparation
    for something else. See also Bureau of Mines, U.S. Dep’t of the
    Interior, A Dictionary of Mining, Mineral, and Related Terms 226
    (Paul W. Thrush ed., 1968) (defining “coal preparation” as a
    “collective term for physical and mechanical processes applied
    to    coal     to     make    it    suitable         for    a    particular      use”).   The
    anticipated use here is consumption at Dominion’s power plant
    across       the    road.     As   Power      Fuels    itself       explains,     Dominion’s
    plant “employs state-of-the-art systems,” and the composition of
    each coal blend produced by Power Fuels “has to meet precise
    specifications to react properly in the furnace burn chamber.”
    Petitioner’s          Br.     at   3,    5.     Even       though    Dominion     sets       the
    specifications, it is the Power Fuels facility that prepares the
    coal     for        the      finely      calibrated,             continually      customized
    13
    consumption process at Dominion’s plant. In letter and spirit,
    the Mine Act extends to facilities of this kind.
    B.
    It is further evident that the type of work performed by
    Power Fuels comes within the purview of the Mine Act. The Act’s
    definition     of    “coal    or    other      mine”    refers       to   the    “work    of
    preparing coal.” 30 U.S.C. § 802(h)(1)(C). Under the statute,
    the   “work    of    preparing         the    coal”    may   involve       an    array    of
    enumerated     actions       --    “breaking,      crushing,     sizing,         cleaning,
    washing,      drying,    mixing,          storing,     and    loading”          coal.    
    Id. § 802(i).
         The   string       of    statutory       verbs    is       indicative      of
    Congress’s      intent       to     regulate       a    comprehensive           range     of
    activities related to coal preparation. More pointedly, several
    of those verbs describe precisely what Power Fuels is doing.
    Power Fuels avers that it does not crush, size, screen, or wash
    coal.   But,    as    Power       Fuels      acknowledges,      it    does      engage    in
    several of the covered functions: the terminal mixes, stores,
    and loads coal.
    Beyond the enumerated activities, the “work of preparing
    the coal” also encompasses “such other work of preparing such
    coal as is usually done by the operator of the coal mine.” 
    Id. Power Fuels
    argues that this phrase serves to limit the listed
    14
    verbs to work “of the type” usually performed by mine operators.
    We do not read the phrase so restrictively.
    We think this phrase is one of inclusion, not exclusion. It
    broadens the range of activities covered rather than limiting
    them. Indeed, the statute tells us that the “work of preparing
    the coal” includes the enumerated verbs “and” also this “other
    work.” 
    Id. (emphasis added).
    Under the grammatical “rule of the
    last antecedent,” the qualifying words (here, “as is usually
    done by the operator of the coal mine”) ordinarily modify only
    the term that they immediately follow (here, “such other work of
    preparing such coal”). See, e.g., Barnhart v. Thomas, 
    540 U.S. 20
    , 26-28 (2003); see also 2A Norman J. Singer & J.D. Shambie
    Singer, Sutherland Statutes and Statutory Construction § 47:33
    (7th ed. 2014). Moreover, the phrase “as is usually done by the
    operator of the coal mine,” 30 U.S.C. § 802(i) (emphasis added),
    refers     to   the     particular    coal     mine       in   question,       not
    a paradigmatic coal-mine operator, as Power Fuels suggests.
    Our interpretation accords not only with the grammatically
    sound    meaning   of   this   provision,    but   also    with   the   mode    of
    analysis mandated by precedent. This court has explained that
    the Mine Act “sets forth a functional analysis, not one turning
    on the identity of the consumer.” United Energy Servs., Inc. v.
    Fed. Mine Safety & Health Admin., 
    35 F.3d 971
    , 975 (4th Cir.
    1994). We have emphasized that “the proper focus of our analysis
    15
    is on the safety of mining operations,” and indeed it is highly
    significant if a company’s “employees are subject to the same
    risks as any other employee engaged in the ‘work of preparing
    coal.’” 
    Id. The inquiry
    turns on how the facility uses the coal
    and whether the employees are exposed to the safety and health
    hazards associated with coal-preparation activities. The text of
    the statute, which defines “coal or other mine” and the “work of
    preparing the coal,” provides basic tools for this functional
    test.    30     U.S.C.    §    802(h)(1)(C),         (i).          Power       Fuels’    blending
    terminal       performs       the    “work    of     preparing            coal”    --     indeed,
    massive       quantities of         coal    each    day       --    and    thereby       subjects
    workers to the risks contemplated in the Mine Act.
    Power    Fuels    contends         that    this   interpretation                admits    no
    limitation. That is incorrect. The limitations are expressed in
    the statute itself. The Mine Act covers those sites used for the
    “work    of     preparing      coal,”      including      “custom          coal    preparation
    facilities,”        like        that       operated           by     Power        Fuels.         
    Id. § 802(h)(1)(C)
    . Covered sites may be engaged, inter alia, in the
    “mixing,”       “storing,”      and    “loading”         of    coal       as    well     as   “such
    other work of preparing such coal as is usually done” by this
    entity. 
    Id. § 802(i).
    Such activities are the reason the Power
    Fuels    facility        is   in     business.      In    fact,       the       statute       seems
    written with coal-preparation sites like Power Fuels’ in mind.
    But the Mine Act does not encompass all companies that burn or
    16
    consume      coal,    and   we    do    not      suggest     that    it      does.    The
    jurisdictional        inquiry     is      more     particularized.        MSHA’s      own
    enforcement guidance indicates that the agency “will not inspect
    facilities where coal is prepared solely to facilitate loading
    and not to meet specifications or to render the coal for any
    particular     use.”    Mine     Safety    &     Health    Admin.,   U.S.     Dep’t   of
    Labor, 1 Program Policy Manual § 3-4, at 2 (rev. ed. June 12,
    2014). In other words, MSHA’s jurisdiction does not extend to
    every facility where coal may in some way be involved. The scope
    of the Act may still exceed what Power Fuels might wish, but
    that of course is a matter of policy entrusted to Congress, not
    the courts.
    By contrast, Power Fuels’ suggested approach may herald a
    return to the era before the Mine Act was enacted in 1977. One
    predecessor statute, the Federal Coal Mine Safety Act, ch. 877,
    66   Stat.    692    (1952),     covered    a    much     narrower   range     of    coal
    operations. Under this 1952 statute, a “mine” was used only for
    the “work of extracting . . . coal” and the “work of processing
    the coal so extracted” by the mine operator. § 201(a)(7), 66
    Stat. at 692 (emphasis added). The “work of processing the coal”
    was restricted to that “usually done by the operator,” and it
    specifically excluded processing activities “usually done by a
    consumer      or     others.”     
    Id. Seventeen years
        later,     Congress
    broadened the statutory coverage in the Federal Coal Mine Health
    17
    and Safety Act of 1969, Pub. L. No. 91-173, 83 Stat. 742. The
    1969 legislation defined a “coal mine” as involved in the “work
    of extracting . . . coal” and the “work of preparing the coal so
    extracted,” and the term’s meaning expressly included “custom
    coal    preparation    facilities.”       § 3(h),    83    Stat.   at   744.     The
    revised law spoke of “preparing” rather than “processing” coal,
    and it eliminated the language from the 1952 statute that had
    excluded coal processing usually done by a consumer or other
    actors. § 3(h), (i), 83 Stat. at 744. Finally, in 1977, Congress
    passed the Mine Act, integrating safety and health protections
    for    miners   of   coal   and   other      minerals     into   one   statute    --
    covering such workers whether they are engaged in extraction,
    milling, or preparation. 30 U.S.C. § 802(h)(1)(C). The present
    Mine    Act   provision,    notably,      no   longer     references    coal     “so
    extracted”: it simply uses the now-familiar term, the “work of
    preparing coal.” Id.; see 
    id. § 802(i).
    The    1977   Mine   Act   has   driven      the    functional    analysis
    employed by this court. We decline the invitation to interpret
    the Mine Act in a way that returns extraction, or other outmoded
    distinctions, to the center of the analysis. Such an approach
    might have been appropriate under the legislative framework that
    prevailed a half century ago. It is not today.

    The parties disagree over the degree of deference we owe to
    the Secretary of Labor’s interpretation. The basic question is
    whether we should defer to the Secretary’s interpretation so
    long as it is reasonable, Chevron U.S.A. Inc. v. Natural Res.
    Def. Council, Inc., 
    467 U.S. 837
    , 842-44 (1984), or whether his
    interpretation is entitled to respect only to the extent of its
    “power to persuade,” Skidmore v. Swift & Co., 
    323 U.S. 134
    , 140
    (1944). But we need not explore that issue. Congress’s intent in
    the Mine Act is plain, and “[i]f the intent of Congress is
    clear, that is the end of the matter.” 
    Chevron, 467 U.S. at 842
    ;
    see    also   
    id. at 843
       n.9.    In     any   event,    the     Secretary’s
    interpretation here warrants respect. See Sec’y of Labor ex rel.
    Wamsley v. Mut. Mining, Inc., 
    80 F.3d 110
    , 114-15 & n.3 (4th
    Cir.   1996).   The      Secretary,     after    all,   is     the    administrator
    charged with overseeing the borderline between the background
    regulations of OSHA and the specialized regulations of MSHA. We
    have been instructed not to “waste [our] time in the mental
    acrobatics needed to decide whether an agency’s interpretation
    of     a      statutory         provision        is     ‘jurisdictional’         or
    ‘nonjurisdictional.’” City of Arlington v. FCC, 
    133 S. Ct. 1863
    ,
    1870 (2013). Instead we are asked to decide, “simply, whether
    the    statutory      text   forecloses         the   agency’s       assertion   of
    authority, or not.” 
    Id. at 1871.
    In this instance, it does not.
