    DUNCAN, Circuit Judge:
    The    National    Labor     Relations      Board      (the    “NLRB”        or   the
    “Board”),    after    notice    and   comment,     promulgated            a    rule    that
    would require employers subject to the National Labor Relations
    Act (the “NLRA” or the “Act”), 
    29 U.S.C. §§ 151-169
    , to post an
    official Board notice informing employees of their rights under
    the Act.      Any employer failing to post the notice would be
    subject to: (1) a finding that it committed an unfair labor
    practice; (2) a tolling of statutes of limitation for charges of
    any other unfair labor practices; and (3) a finding of anti-
    union   animus   that   would     weigh   against      it    in     any       proceedings
    before the Board.           Notification of Employee Rights Under the
    National    Labor    Relations    Act,    
    76 Fed. Reg. 54,006
           (Aug.    30,
    2011) (codified at 29 C.F.R. pt. 104).
    The Chamber of Commerce of the United States and the South
    Carolina    Chamber     of     Commerce   (collectively,            “the        Chamber”)
    sought final review of the rule.               The district court determined
    that in promulgating the notice-posting rule, the Board exceeded
    its authority, in violation of the Administrative Procedure Act
    (the “APA”).        Looking to the plain language of the NLRA, its
    structure, its legislative history, and the notice provisions in
    other   statutes,     the    court    concluded       that    the    Act        does   not
    provide the Board with the power to enact such a rule.                                  The
    court therefore granted summary judgment to the Chamber.
    4
    We    agree   with   the   district        court    that    the    rulemaking
    function provided for in the NLRA, by its express terms, only
    empowers the Board to carry out its statutorily defined reactive
    roles in addressing unfair labor practice charges and conducting
    representation     elections    upon    request.         Indeed,    there   is   no
    function or responsibility of the Board not predicated upon the
    filing of an unfair labor practice charge or a representation
    petition.    We further note that Congress, despite having enacted
    and amended the NLRA at the same time it was enabling sister
    agencies to promulgate notice requirements, never granted the
    Board the statutory authority to do so.                 We therefore hold that
    the Board exceeded its authority in promulgating the challenged
    rule, and affirm.
    I.
    After discussing the structure and purpose of the NLRA, we
    describe the background of the challenged rule.                 We then briefly
    recount the procedural history of this case.
    A.
    1.
    The    NLRA    governs      relations        between       private     sector
    employers, labor unions, and employees.                  Congress enacted the
    NLRA--originally    referred     to    as   the   “Wagner       Act,”   after    its
    sponsor, Senator Robert F. Wagner--in 1935.                Pub. L. No. 74-198,
    5
    
    49 Stat. 449
     (1935).           The Act has since been amended three
    times, most recently in 1974.               See Labor Management Relations
    Act   (“Taft-Hartley      Act”),    Pub.     L.   No.     80-101,       
    61 Stat. 136
    (1947); Labor Management Reporting and Disclosure Act (“Landrum-
    Griffin Act”), Pub. L. No. 86-257, 
    73 Stat. 519
     (1959); Health
    Care Amendments, Pub. L. No. 93-360, 
    88 Stat. 395
     (1974).
    The first section of the Act lays out the national labor
    policy, which the Board is intended to promote “by encouraging
    the   practice   and      procedure    of    collective        bargaining        and   by
    protecting     the     exercise     by      workers       of     full        freedom   of
    association,         self-organization,             and          designation           of
    representatives      of    their    own     choosing,      for    the        purpose   of
    negotiating    the   terms    and     conditions      of    their       employment     or
    other mutual aid or protection.”                 
    29 U.S.C. § 151
    .              Section 2
    provides definitions, and Sections 3, 4, and 5 establish the
    Board and lay out its structure. 1
    1
    Although the structure of the Board is not at issue in
    this case, it bears noting that the Secretary of Labor at the
    time of the NLRA’s passage expressed concern that while the NLRB
    was to be “judicial in character,” the “disconcerting tasks of
    administration” might make it “subject to distraction from
    specific cases by the temptation to strengthen its prestige
    through educational and administrative activities.”    H.R. Rep.
    No. 74-969 (1935), reprinted in 2 NLRB, Legislative History of
    the National Labor Relations Act, 1935, at 2919 (1949) (“NLRA
    Leg. Hist.”).
    6
    Section 6--the focus of this case--confers rulemaking power
    on the Board, providing it with the “authority from time to time
    to make, amend, and rescind, in the manner prescribed by [the
    APA], such rules and regulations as may be necessary to carry
    out the provisions of [the NLRA].”                 
    Id.
     § 156.      Section 7 lists
    employees’ core labor rights, including the rights to organize,
    join    unions,      bargain     collectively      through      representatives         of
    their    choosing,         and     engage    in    concerted       activities          for
    collective bargaining or mutual aid and protection.                            Section 8
    lays    out   five    specific     unfair    labor    practices      (“ULPs”).          Of
    particular significance to this case, Section 8(a)(1) makes it a
    ULP “to interfere with, restrain, or coerce employees in the
    exercise      of   the    rights     guaranteed    in     [Section      7].”      Id.    §
    158(a)(1).         Section 8(c) provides that the expression of views
    in any form “shall not constitute or be evidence of [a ULP] . .
    ., if such expression contains no threat of reprisal or force or
    promise of benefit.”           Id. § 158(c).
    The    core,      specified    functions      of   the    NLRB     are    (1)    to
    conduct representation elections, and (2) to prevent and resolve
    ULPs.     Section 9 of the NLRA provides for the first of these,
    authorizing the filing of representation petitions, in which a
    petitioner alleges that a substantial number of employees wish
    to be represented by a union for collective bargaining.                            Under
    that    section,      the    Board     has   the     authority       to   investigate
    7
    questions of representation, hold secret-ballot elections, and
    certify the results thereof.             Section 10 provides the Board with
    the authority to investigate, prevent, and remedy ULPs.                             All
    proceedings under Sections 9 and 10 “originate with the filing
    of   charges   or    petitions      by    employees,       labor   unions,    private
    employers,     and     other     private      parties.”            NLRB,     2011    FY
    Performance     and     Accountability            Report     12,     available      at
    http://www.nlrb.gov/sites/default/files/documents/189/nlrb_2011_
    par_508.pdf (last visited May 31, 2013); see also Notification
    of Employee Rights Under the National Labor Relations Act, 76
    Fed. Reg. at 54,010 (“In both instances, the initiating document
    is filed by a private party.”).              Thus, “[a]lthough the Board is
    specifically empowered to ‘prevent’ unfair labor practices, ‘the
    Board may not act until an unfair labor practice charge is filed
    alleging a violation of the Act.’                  In addition, certification
    ‘procedures     are     set    in        motion    with      the    filing     of    a
    representation       petition.’”          Notification       of    Employee    Rights
    Under the National Labor Relations Act, 76 Fed. Reg. at 54,010
    (quoting 2 The Developing Labor Law 2662, 2683 (John E. Higgins,
    Jr. ed., 5th ed. 2006)) (alterations omitted). 2
    2
    As we discuss in comparing the NLRA to other federal                     labor
    legislation, the NLRB’s reactive mandate stands in                              stark
    contrast to the proactive roles of other labor agencies                          that
    have promulgated notice-posting requirements.     While the                      NLRA
    only provides for processes that may be initiated by                            third
    (Continued)
    8
    The   final       provision      relevant        to    this   case,     Section      11,
    gives the Board investigatory powers “necessary and proper for
    the exercise of the powers vested in [the Board]” by Sections 9
    and 10, including the right to issue subpoenas.                          29 U.S.C § 161.
    Because of the reactive nature of the Board’s functions under
    Sections     9    and     10,    Section       11   provides     it     with    no   “roving
    investigatory powers.”                 Notification of Employee Rights Under
    the National Labor Relations Act, 76 Fed. Reg. at 54,010; see
    also H.R. Rep. No. 74-969 (1935), reprinted in 2 NLRA Leg. Hist.
    at 2932.
    2.
    The       Board     promulgated          the      challenged          rule,    titled
    “Notification        of    Employee        Rights       Under    the     National       Labor
    Relations Act,” on August 30, 2011, after a notice and comment
    period.      Notification          of    Employee       Rights       Under    the    National
    Labor   Relations         Act,    76    Fed.    Reg.     at    54,006.         The   rule    is
    composed of three subparts.                    Subpart A, which is at issue in
    this appeal, provides that “[a]ll employers subject to the NLRA
    must post notices to employees, in conspicuous places, informing
    them    of   their        NLRA     rights,          together     with        Board   contact
    parties, the authorizing legislation of these sister agencies
    speaks to investigatory and enforcement functions that the
    agencies may themselves initiate. See infra Part II.B.4.
    9
    information      and    information      concerning      basic    enforcement
    procedures.”      
    29 C.F.R. § 104.202
    (a).          The text of the notice
    explains to employees:
    The [NLRA] guarantees the right of employees to
    organize    and  bargain    collectively   with   their
    employers, and to engage in other protected concerted
    activity or to refrain from engaging in any of the
    above activity.    Employees covered by the NLRA are
    protected from certain types of employer and union
    misconduct. This Notice gives you general information
    about your rights, and about the obligations of
    employers and unions under the NLRA.       Contact the
    [NLRB], the Federal agency that investigates and
    resolves complaints under the NLRA, using the contact
    information supplied below, if you have any questions
    about   specific  rights   that   may  apply   in  your
    particular workplace.
    
    Id.
     at Pt. 104, Subpt. A, App. (footnote omitted).                 It goes on
    to list employees’ rights under the Act and provide information
    as to how to “contact the NLRB promptly to protect your rights.”
    
    Id.
    Subpart B makes failure to post the employee notice a ULP
    under Section 8(a)(1) of the NLRA.            
    Id.
     § 104.210.     If, after an
    adjudication, the Board finds that an employer has failed to
    post the required notice, the Board will order the employer to
    cease    and   desist   the   unlawful   conduct   and   post    the   required
    notice, along with a remedial notice.              Id. § 104.213.        If an
    employee files a ULP charge complaining that an employer has
    failed to post a notice, the Board may excuse the employee from
    the usual six-month statute of limitations for any other ULP
    10
    charges.      Id. § 104.214(a).        Finally, the rule allows the Board
    to “consider a knowing and willful refusal to comply with the
    requirement to post the employee notice as evidence of unlawful
    motive” in other proceedings before it.                Id. § 104.214(b). 3
    The Board’s principal rationale for introducing the notice-
    posting rule was that “American workers are largely ignorant of
    their rights under the NLRA, and this ignorance stands as an
    obstacle to the effective exercise of such rights.”                         Proposed
    Rules      Governing    Notification     of        Employee     Rights    Under     the
    National Labor Relations Act, 
    75 Fed. Reg. 80,410
    , 80,411 (Dec.
    22, 2010) (codified at 29 C.F.R. pt. 104).                    The Board pointed to
    the changing nature of the American workforce as part of the
    cause of this knowledge gap--in particular, the Board noted that
    “[t]he overwhelming majority of private sector employees are not
    represented     by     unions,   and   thus    lack    an     important   source    of
    information about NLRA rights”; “[i]mmigrants, who comprise an
    increasing proportion of the nation’s work force, are unlikely
    to    be   familiar    with   their    workplace      rights,       including     their
    rights under the NLRA”; and “high school students, many of whom
    are about to enter the labor force, are uninformed about labor
    law    and   labor     relations.”      
    Id.
             The     Board   explained      that
    3
    Subpart C of the rule contains ancillary provisions not
    relevant to this appeal.
    11
    employees’ lack of awareness of their rights stems in part from
    the absence of any requirement that they be informed of those
    rights.    The Board noted that “[t]he NLRA is almost unique among
    major Federal labor laws in not including an express statutory
    provision requiring employers routinely to post notices at their
    workplaces informing employees of their statutory rights.”                 
    Id.
     4
    The challenged rule is unusual in several respects.                    The
    Board has only rarely engaged in rulemaking during its seventy-
    seven year history.         And it has never promulgated a notice-
    posting rule of any kind. 5
    In the public comment period that followed the promulgation
    of   the   rule,   the   Board   received   over    7,000   submissions,     the
    majority     of    which   opposed    the    rule     or    aspects   of     it.
    4
    As the Board observed, a number of other federal labor
    statutes contain explicit employee notice provisions.        See
    Railway Labor Act (“RLA”), 
    45 U.S.C. § 152
    , Fifth, Eighth; Title
    VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e-10(a);
    Age Discrimination in Employment Act, 
    29 U.S.C. § 627
    ;
    Occupational Health and Safety Act, 
    29 U.S.C. § 657
    (c); Employee
    Polygraph Protection Act, 
    29 U.S.C. § 2003
    ; Americans with
    Disabilities Act, 
    42 U.S.C. § 12115
    ; Family and Medical Leave
    Act, 
    29 U.S.C. § 2619
    (a); Uniformed Service Employment &
    Reemployment Rights Act, 
    38 U.S.C. § 4334
    (a).
    5
    The Board has, on a case-by-case basis, required
    individual employers found to have committed ULPs to post
    remedial Board-supplied notices informing employees of their
    rights under the Act.   See, e.g., Smithfield Packing Co.,

    B.
    On September 19, 2011, before the rule went into effect,
    the Chamber filed a complaint in the District Court for the
    District of South Carolina for injunctive relief against the
    NLRB, its Members, and its General Counsel.                 The parties filed
    cross motions for summary judgment on November 9, 2011, and the
    district court granted summary judgment to the Chamber on April
    13, 2012.   This appeal followed.
    Concurrently,         the    National     Association      of    Manufacturers
    filed a suit against the NLRB in the District Court for the
    District of Columbia.           See Nat’l Ass’n of Mfrs. v. NLRB,

    Additionally, Member Brian Hayes dissented from the
    Board’s Notice of Proposed Rulemaking, arguing that “[t]he Board
    lacks the statutory authority to promulgate or enforce” the
    rule.  Proposed Rules Governing Notification of Employee Rights
    Under the National Labor Relations Act, 75 Fed. Reg. at 80,415.
    Specifically, Member Hayes determined that Section 6 was not
    sufficient authority for imposing such a requirement: “[t]o the
    contrary, Section 10 of the Act indicates to me that the Board
    clearly lacks the authority to order affirmative notice-posting
    action in the absence of an unfair labor practice charge filed
    by an outside party.”    Id.  Member Hayes ultimately dissented
    from the promulgation of the final rule as well.    Notification

    Supp. 2d 34 (D.D.C. 2012).      That court granted summary judgment
    to the NLRB.      The National Association of Manufacturers appealed
    to   the   D.C.   Circuit,   which    reversed   the   district   court’s
    decision, holding that the notice-posting rule violates Section
    8(c) of the NLRA, which prohibits the NLRB from finding employer
    speech that is not coercive to be a ULP or evidence of a ULP.

    (D.C. Cir. May 7, 2013). 7           Judge Henderson, joined by Judge
    Brown, wrote a concurrence, opining that the Board also lacked
    authority under Section 6 to issue the rule.

     (Henderson,
    J., concurring).
    II.
    A.
    Preliminary to our consideration of the challenged rule are
    threshold inquiries as to the appropriate mode of analysis.            We
    first address the Board’s proposition that the notice-posting
    rule should be analyzed under the deferential standard set forth
    in Mourning v. Family Publications Service, Inc., 
    411 U.S. 356
    7
    Although the Chamber made a similar argument below, the
    parties did not address this issue in their briefs or during
    oral argument before this court. Because we determine that the
    Board had no authority to issue the rule, we do not reach the
    question of whether it was also precluded from doing so by
    Section 8(c).
    14
    (1973).         Next, we choose between two competing lenses through
    which to analyze the issue of the Board’s authority, determining
    if,   as    the       Board   contends,      the      relevant      question      is    whether
    Congress intended to withhold authority to issue the challenged
    rule from the Board, or if, as the Chamber argues, the relevant
    question is whether Congress intended to grant that authority.
    1.
    We start with the Board’s argument that the challenged rule
    is properly analyzed under Mourning.                             Mourning instructs that
    rules issued pursuant to broad rulemaking grants such as Section
    6   are    to     be    upheld   if    they     are        “reasonably      related     to     the
    purposes         of    the    enabling       legislation.”              
    411 U.S. at 369
    (citations and internal quotation marks omitted).                                     The Board
    reasons that Mourning provides the appropriate framework because
    while      the    familiar       two-step       mode        of    analysis      laid    out    by
    Chevron,        U.S.A.,       Inc.   v.   Natural          Resources       Defense     Council,
    Inc., 
    467 U.S. 837
     (1984), applies to an agency’s construction
    of a statute, “Mourning’s aim is to analyze substantive rules
    that carry out an agency’s enabling act, but do not necessarily
    interpret specific statutory language.”                          Appellant’s Br. at 5.
    We    find       this    distinction          untenable.            Mourning,     a     pre-
    Chevron     case,       requires      that      a    court       “defer    to   the    informed
    experience and judgment of the agency to whom Congress delegated
    appropriate           authority.”         
    411 U.S. at 372
         (emphasis     added).
    15
    Thus, Mourning applies only after a court has determined that
    Congress    has   indeed      delegated    interpretative       powers     to   that
    agency.      See AFL-CIO v. Chao, 
    409 F.3d 377
    , 384 (D.C. Cir.
    2005); see also City of Arlington v. FCC, --- S. Ct. ----, 
    2013 WL 2149789
    , at *8-9 (May 20, 2013) (holding that the Chevron
    framework    applies      to    an     agency’s     statutory     interpretation
    concerning the scope of its own authority).
    2.
    Notwithstanding the facial inapplicability of Mourning, the
    Board contends that it should be considered to have the power to
    promulgate    the      rule   unless    Congress     expressly    withheld      that
    authority.
    The Chamber, on the other hand, contends that we should
    invalidate the notice-posting rule unless we find that Congress
    intended to delegate to the Board the power to issue it.                         The
    Chamber’s view finds support in our precedent.                  Specifically, in
    determining the appropriate framework under which to analyze the
    Food and Drug Administration’s (“FDA’s”) power to promulgate a
    challenged     regulation,       we    deemed      the   question     of   whether
    Congress intended to grant authority the appropriate one.                        See
    Brown & Williamson Tobacco Corp. v. FDA, 
    153 F.3d 155
    , 161 (4th
    Cir. 1998) (“The district court framed the issue as ‘whether
    Congress has evidenced its clear intent to withhold from FDA
    jurisdiction      to     regulate      tobacco     products      as   customarily
    16
    marketed.’          However,   we    are     of       opinion     that     the       issue    is
    correctly framed as whether Congress intended to delegate such
    jurisdiction to the FDA.”), aff’d, 
    529 U.S. 120
     (2000).                                    Other
    courts have followed the same approach.                           See, e.g., Am. Bar
    Ass’n v. FTC, 
    430 F.3d 457
    , 468 (D.C. Cir. 2005) (“Plainly, if
    we were ‘to presume a delegation of power’ from the absence of
    ‘an   express   withholding         of    such    power,        agencies       would       enjoy
    virtually limitless hegemony . . . .’” (quoting Ry. Labor Execs.
    Ass’n    v.   Nat’l    Mediation     Bd.,       
    29 F.3d 655
    ,     671    (D.C.       Cir.
    1994))); Sierra Club v. EPA, 
    311 F.3d 853
    , 861 (7th Cir. 2002)
    (“Courts ‘will not presume a delegation of power based solely on
    the   fact    that    there    is   not    an     express         withholding         of    such
    power.’” (quoting Am. Petroleum Inst. v. EPA, 
    52 F.3d, 1113
    ,
    1120 (D.C. Cir. 1995))).
    In support of its contention to the contrary, the Board
    cites American Hospital Association v. NLRB (“AHA”), 
    499 U.S. 606
     (1991).     In AHA, the Supreme Court addressed a challenge to
    a   rule   defining     collective        bargaining          units    for      acute       care
    hospitals.      The plaintiffs there argued that because Section
    9(b) of the NLRA requires the Board to make bargaining unit
    determinations        “in   each    case,”       the    Board      could       not    use    its
    general rulemaking power under Section 6 to define bargaining
    units.        The     Court    determined         that        because      Section          9(a)
    authorizes     the    Board    to   decide       whether      a    designated         unit    is
    17
    appropriate for the purposes of collective bargaining, it could
    promulgate      a    rule    proactively         defining     collective        bargaining
    units   in    acute        care   hospitals,       rather     than    determining        the
    composition      of       such    units    through     case-by-case         adjudication.
    The Court noted that “[a]s a matter of statutory drafting, if
    Congress had intended to curtail in a particular area the broad
    rulemaking authority granted in § 6, we would have expected it
    to do so in language expressly describing an exception from that
    section   or    at     least      referring       specifically       to   the    section.”
    AHA, 
    499 U.S. at 613
    .
    The language in AHA that provides the basis for the Board’s
    argument, arising as it does in the context of a bargaining unit
    determination         as    to    which    the    Board   has    been       legislatively
    granted authority, is inapplicable to the challenged rule.                                At
    issue   in     AHA    was    whether       Section     9(b)    limited       the    Board’s
    general      authority--granted             by     Section      6--to       enact      rules
    necessary to carry out Section 9.                      Here, on the other hand,
    there is simply no authority to be limited: as we emphasize
    again, there is no general grant of power to the NLRB outside
    the     roles        of     addressing           ULP   charges        and       conducting
    representation elections.                 Indeed, the fact that none of the
    Act’s   provisions          contain       language     specifically         limiting    the
    Board’s authority to enact a notice-posting requirement reflects
    18
    the absence of statutory authority for actions outside those
    defined responsibilities as a threshold matter.
    Moreover, in AHA, the Supreme Court was careful to limit
    its determination that authority existed for the promulgation of
    “the rule at issue in this case unless limited by some other
    provision in the Act.”          
    499 U.S. at 610
     (emphasis added).                   This
    narrow   statement     must     be    read    in    its   context;     it   does    not
    support the proposition that the NLRB may enact any rule it
    wishes   unless     some   provision      of    the    Act    expressly     withholds
    authority for it to do so, when no general authority has been
    given by Congress in the first instance.                     Thus, in our analysis
    here, we focus on the question of whether Congress intended to
    grant the NLRB the authority to issue the challenged rule--and
    not whether Congress intended to withhold that power.
    B.
    Having   determined       the    appropriate        framework,   we     consider
    the notice-posting rule under Chevron.                 We ask “whether Congress
    has directly spoken to the precise question at issue.                          If the
    intent of Congress is clear, that is the end of the matter; for
    the   court,   as   well   as    the    agency,       must    give   effect    to    the
    unambiguously expressed intent of Congress.”                     
    467 U.S. at
    842-
    43.   Only “if the statute is silent or ambiguous with respect to
    the specific issue” are we to proceed to Chevron’s second step,
    19
    asking “whether the agency’s answer is based on a permissible
    construction of the statute.”             
    Id. at 843
    .
    Under Chevron’s first step, we must use the “traditional
    tools   of     statutory     construction”            to   ascertain       congressional
    intent.      
    467 U.S. at
    842 n.9.            We thus look to the text of the
    statute, along with “the overall statutory scheme, legislative
    history, the history of evolving congressional regulation in the
    area, and . . . other relevant statutes.”                         Brown & Williamson,
    153 F.3d at 162 (citations and quotation marks omitted).                          We are
    only to employ the deference of step two when the “devices of
    judicial     construction      have    been      tried      and    found   to   yield   no
    clear sense of congressional intent.”                      Gen. Dynamics Land Sys.,
    Inc. v. Cline, 
    540 U.S. 581
    , 600 (2004).                           Because we do not
    presume a delegation of power simply from the absence of an
    express    withholding       of    power,    we       do   not    find   that   Chevron’s
    second step is implicated “any time a statute does not expressly
    negate the existence of a claimed administrative power.”                                Am.
    Bar   Ass’n,    
    430 F.3d at 468
         (citation       and    internal     quotation
    marks omitted).
    1.
    In assessing the validity of the notice-posting rule, we
    begin by examining the plain language of the NLRA.                               See CSX
    Transp., Inc. v. Ala. Dep’t of Revenue, 
    131 S. Ct. 1101
    , 1107
    (2011).      Thus, we look to the text of Section 6 of the Act,
    20
    which    grants     the      Board     authority             to    issue          rules       that    are
    “necessary to carry out” the provisions of the Act.                                        
    29 U.S.C. § 156
    .
    We, like the Chamber, read the language in Section 6 as
    requiring that some section of the Act provide the explicit or
    implicit    authority         to    issue        a    rule.        Because             the    Board    is
    nowhere charged with informing employees of their rights under
    the NLRA, we find no indication in the plain language of the Act
    that    Congress       intended       to    grant       the       Board       the      authority       to
    promulgate such a requirement.
    The Board contests this reading of the statute, arguing
    that the word “necessary” is inherently ambiguous, bringing us
    directly to Chevron’s step two.                        In support of this argument,
    the Board relies, in part, on language from Mourning explaining
    that    “[w]here       the    empowering             provision      of        a    statute       states
    simply     that    the       agency        may       ‘make    .    .      .       such       rules    and
    regulations as may be necessary to carry out the provisions of
    this    Act,’”    we    are    to     sustain         the     validity            of   a     regulation
    promulgated thereunder “so long as it is ‘reasonably related to
    the purposes of the enabling legislation.’”                                       
    411 U.S. at 369
    (citations       omitted).          However,           as     we    have          explained,         this
    guidance is relevant only once we have determined that a statute
    is ambiguous.          That is, we are only to defer to an agency’s
    interpretation of what is “necessary” once we have progressed to
    21
    Chevron’s second step.         Mourning’s exhortation that we “defer to
    the   informed    experience       and   judgment      of   the    agency      to   whom
    Congress   delegated        appropriate    authority,”         
    id. at 372
    ,    thus
    cannot    be    read   as    requiring     us    to    defer      to   the    agency’s
    interpretation as we conduct our initial analysis of the Act.
    Moreover, even if the term “necessary,” standing on its
    own, may be deemed ambiguous, we need not automatically defer to
    the Board’s interpretation.              “‘Mere ambiguity in a statute is
    not evidence of congressional delegation of authority.’”                             Am.
    Bar Ass’n, 
    430 F.3d at 469
     (quoting                   Michigan v. EPA, 
    268 F.3d 1075
    , 1082 (D.C. Cir. 2001)).             Rather, “[t]he ambiguity must be
    such as to make it appear that Congress either explicitly or
    implicitly delegated authority to cure that ambiguity.”                              
    Id.
    “Even when Congress has stated that the agency may do what is
    ‘necessary,’ whatever ambiguity may exist cannot render nugatory
    restrictions that Congress has imposed.”                    AFL-CIO, 
    409 F.3d at 384
     (citation omitted).            Thus, as the district court correctly
    observed, “[t]he Board may not disregard restrictions Congress
    has imposed on its authority in other sections of the governing
    statute    by    relying      on    Section      6    in    isolation        to     these
    substantive provisions.”            Chamber of Commerce v. NLRB, 
    856 F. 22
    Supp. 2d 778, 790 (D.S.C. 2012). 8               As we discuss in greater
    detail below, the substantive provisions of the Act make clear
    that the Board is a reactive entity, and thus do not imply that
    Congress   intended    to   allow     proactive   rulemaking   of   the   sort
    challenged     here   through   the    general    rulemaking   provision   of
    Section 6. 9
    2.
    Continuing with our analysis of the rule under Chevron’s
    first step, we next consider the structure of the NLRA.                    “In
    8
    The Ninth Circuit drew the same conclusion in striking
    down an NLRB regulation prohibiting Board employees from
    producing files in response to subpoenas, reasoning that
    although Section 6 authorizes the Board to “adopt rules and
    regulations to carry out its functions in a manner consistent
    with the fulfillment of the purposes of the Act,” the statute
    “does   not  authorize   the  Board   to promulgate  rules  and
    regulations which have the effect of enlarging its authority
    beyond the scope intended by Congress.”     Gen. Eng’g, Inc. v.
    NLRB, 
    341 F.2d 367
    , 374 (9th Cir. 1965).
    9
    The Board points out that in AHA the Supreme Court
    approved the Board’s promulgation of a rule defining certain
    bargaining units proactively--rather than in response to the
    filing of a representation petition--as an acceptable use of the
    power delegated to the Board under Section 6.       However, the
    determination of bargaining units is one of the roles Congress
    expressly intended the Board to play. See 
    29 U.S.C. § 159
    . In
    contrast, the NLRA--unlike many other labor statutes--is silent
    as to any role for its administering agency in enacting notice-
    posting requirements or any affirmative duty for employers to
    post notices.     Moreover, as the district court noted, the
    bargaining units rule at issue in AHA “defined how the Board
    would handle issues after the Board’s adjudicative authority was
    triggered.” Chamber of Commerce, 856 F. Supp. 2d at 791. Here,
    the Board attempts something distinct and novel: the proactive
    imposition of a duty upon employers that does not flow from any
    of the provisions of the Act.
    23
    determining     whether     Congress     has       specifically       addressed     the
    question at issue, a reviewing court should not confine itself
    to examining a particular statutory provision in isolation.                          The
    meaning--or    ambiguity--of        certain        words   or   phrases      may   only
    become     evident   when     placed    in    context.”         FDA     v.   Brown    &
    Williamson Tobacco Corp., 
    529 U.S. 133
    , 132 (2000).                          Thus, in
    addition to the language of Section 6 itself, we must look to
    “the specific context in which that language is used, and the
    broader context of the statute as a whole.”                      McLean v. United
    States, 
    566 F.3d 391
    , 396 (4th Cir. 2009) (quoting                      Robinson v.
    Shell Oil Co., 
    519 U.S. 337
    , 341 (1997)).                   An examination of the
    rest of the Act reveals no provision that a notice-posting rule
    is “necessary” to carry out.
    The    Board    points    to   a   number       of    sections    in    the   Act,
    arguing that the rule is necessary to carry them out.                               The
    Chamber responds that no provision in the Act requires employers
    who have not committed labor violations to be subject to a duty
    to post employee notices.           We agree.        The NLRB serves expressly
    reactive      roles:      conducting         representation       elections          and
    resolving ULP charges.         As an examination of the Act as a whole
    makes evident, none of its sections imply that Congress intended
    to grant the Board authority to issue the notice-posting rule
    sua sponte.
    24
    First,     Section         1,       which     lays        out      the     purpose       and
    aspirations       of    the     NLRA,       does     not     provide        the    Board     with
    authority to act.           The Board argues that because Section 1 sets
    forth   the     Act’s     policy       in    broad        terms,    it     is     “specifically
    designed to permit the Board to spell out [its] applications.”
    Appellant’s Br. at 39.                However, any argument that the statute’s
    statement of purpose can provide the agency with the authority
    to promulgate any regulation in furtherance of that purpose is
    unavailing.         The    NLRB       is    “‘bound,       not     only    by     the   ultimate
    purposes Congress has selected, but by the means it has deemed
    appropriate,        and        prescribed,          for      the       pursuit       of     those
    purposes.’”        Colo. River Indian Tribes v. Nat’l Indian Gaming
    Comm’n,     
    466 F.3d 134
    ,    139        (D.C.     Cir.       2006)    (quoting        MCI
    Telecomms. Corp. v. AT&T, 
    512 U.S. 218
    , 231 n.4 (1994)).
    Similarly, Section 7, which lists rights protected under
    the Act, does not provide the Board with specific authority to
    act.      Indeed,       language       in    the    Board’s        own    brief     belies      its
    argument.         The     Board       contends      that     the       challenged        rule    is
    necessary to “carry out the core rights set forth by Section 7.”
    Appellant’s       Br.     at     11     (internal          quotation       marks        omitted).
    However, while these rights exist thanks to the NLRA and are to
    be protected in the manner set forth by the NLRA’s provisions,
    significantly,         rights     are       not    functions       or     provisions       to    be
    “carried out.”           See Nat’l Ass’n of Mfrs., 
    2013 WL 1876234
    , at
    25
    *15 (Henderson, J., concurring) (“Neither [Section 1 nor Section
    7] contains any particularized ‘provision’ that the Board can
    ‘carry out’ by regulation or otherwise.”).
    Nor     does    Section       8,    which    defines         ULPs    under    the     Act,
    provide     the    Board    with    the    power       to    require      the    posting     of
    notices.      The Board notes that its authority under Section 6
    extends     to    defining       what     constitutes         a     ULP    under     Section
    8(a)(1), and argues that Section 8 thus gives it authority to
    promulgate the notice-posting rule, which makes it a ULP to fail
    to post the employee notice.                   Specifically, from its power to
    interpret what constitutes “interfere[nce] with, restrain[t], or
    coerc[ion of] employees in the exercise of the rights guaranteed
    in [Section 7],” 
    29 U.S.C. § 158
    (a)(1), the Board attempts to
    extract the authority to create a new ULP based on the failure
    to   post    notices       educating      employees          about       their    Section    7
    rights.           While     we     recognize          that     the       Board     has      the
    responsibility        to    “adapt       the     Act    to    changing          patterns    of
    industrial life,” NLRB v. J. Weingarten, Inc., 
    420 U.S. 251
    , 266
    (1975), and that Congress did not “undertake the impossible task
    of specifying in precise and unmistakable language each incident
    which   would       constitute      an    unfair       labor       practice,”       Republic
    Aviation Corp. v. NLRB, 
    324 U.S. 793
    , 798 (1945), we cannot
    accept an interpretation of the Act that would allow the NLRB to
    26
    bootstrap       Section        8(a)(1)    into     authority      to     enact       the
    unprecedented rule at issue here.
    Finally, and of most significance, the notice-posting rule
    is not “necessary to carry out” Sections 9 and 10, which set
    forth the Board’s responsibilities for conducting representation
    elections and adjudicating ULP charges.                   As we have discussed,
    Sections 9 and 10 lay out reactive roles for the Board; the
    processes they provide for are not set in motion until a party
    files a representation petition or a ULP charge.                          The Board
    contends that the Act presupposes knowledge of NLRA rights and
    their enforcement mechanisms, and that “employee knowledge of
    NLRA rights and how to enforce them within statutory timeframes
    is   crucial     to    effectuate        Congress’s      national      labor   policy
    through the processes established by Sections 8, 9, and 10.”
    Appellant’s      Br.   at      12.    Essentially,       the   Board    argues      that
    because the enforcement functions provided for by Sections 9 and
    10   are   reactive,      it    was   necessary     to   proactively     create     the
    challenged rule in order for employees to undertake their role
    in instigating those processes.               With this reasoning, the Board
    attempts to derive from provisions governing the functions and
    operation of the agency the authority to do something entirely
    distinct from those functions, with the rationale that doing so
    would    make   them   more      effective.        However,    regardless      of   how
    laudable the NLRB’s goal of educating workers may be, “there is
    27
    nothing in the text of the NLRA to suggest the burden of filling
    the ‘knowledge gap’ should fall on the employer’s shoulders.”
    Nat’l Ass’n of Mfrs., 
    2013 WL 1876234
    , at *16 (Henderson, J.,
    concurring).   Put simply, we cannot accept the Board’s circular
    argument; the Board may not justify an expansion of its role to
    include proactive regulation of employers’ conduct by noting its
    reactive role under the Act. 10
    10
    The Board also cites Section 11 of the Act in support of
    its argument that had Congress intended to limit the Board’s
    authority to promulgate the notice-posting regulation, it would
    have expressed that limitation somewhere in the statute.        The
    Board   contrasts   Section    6,  which   contains   no  words  of
    limitation, with Section 11, which details the Board’s subpoena
    power but explicitly limits that authority to “hearings and
    investigations . . . necessary and proper for the exercise of
    the powers vested in [the Board] by sections [9] and [10].” 
    29 U.S.C. § 161
    . This language in Section 11 demonstrates, argues
    the Board, that “when Congress wants to limit the Board’s power
    by reference to Sections 9 and 10, it does so explicitly.”
    Appellant’s Br. at 30.        We find this comparison unavailing
    because it is based on the incorrect premise that the Board
    should be considered to have the power to issue the challenged
    rule   unless   Congress    expressly   withheld   that  authority.
    Moreover, we note that in Section 11, the NLRA creates a
    specific power, to which it attached specific limits.           The
    authority delegated under Section 6 is unquestionably broader,
    but as we have explained, the fact that Congress did not attach
    explicit limits to it does not make it limitless. Furthermore,
    detailing limits similar to those in Section 11 could have
    constrained the Board in ways not intended by Congress.         See
    Appellees’ Br. at 20 n.4 (“[I]t would not have made sense for
    Congress to limit the Board’s rulemaking authority only to
    Section 9 and 10 of the Act because that would have prevented
    the Board, for example, from promulgating rules defining any
    ambiguous provisions in Section 8.”).
    28
    Contrary to the Board’s assertions, our analysis of the
    Act’s structure comports with the Supreme Court’s holding in
    AHA.        At   issue   in   AHA   was   whether   the   Board   could   define
    employee bargaining units proactively and universally, outside
    the context of case-by-case adjudication.                 In that case, even
    the challengers of the rule conceded that the Board could make
    such a determination through adjudication.                 AHA, 
    499 U.S. at 612
    .    Here, in contrast, the question is not whether the notice-
    posting requirement could be established through rulemaking as
    opposed to adjudication, but whether the Board has the authority
    to require universal, preemptive notice-posting at all. 11                   The
    Board’s contention that AHA established that the NLRB has the
    authority to undertake proactive measures such as the challenged
    regulation thus reads the Court’s opinion too broadly. 12
    11
    We do not take issue with the Board’s practice of
    requiring individual employers to post notices on a case-by-case
    basis in response to ULP adjudications. See supra note 5.
    12
    The Board cites a number of cases in which it has
    articulated rules of general applicability through adjudication
    in arguing that it could have developed the challenged rule
    through case-by-case adjudication.   See, e.g., St. Francis Med.
    Ctr., 
    347 N.L.R.B. 368
    , 369 (2006); Tech. Serv. Solutions, 
    324 N.L.R.B. 298
    , 301 (1997); Champagne Color, Inc., 
    234 N.L.R.B. 82
    , 82 (1978).     However, those cases were all adjudications
    resulting from ULPs and based on rights explicitly granted by
    the NLRA. Here, the Board seeks to create a duty and a ULP from
    whole cloth, based not on the rights enumerated in the NLRA,
    which it does not specifically assert employers are infringing,
    but on employees’ need--nowhere mentioned in the NLRA--to be
    made aware of their rights under the Act.
    29
    3.
    We    also      find        the     history         of     the     NLRA       instructive,
    particularly         vis-a-vis            congressional                treatment       of    sister
    agencies with statutory authorization to require the posting of
    notices.          We     find        that     the        Act’s          history       provides    no
    countervailing evidence of an intent to bestow the Board with
    the power to enact the challenged regulation.
    Reports on early versions of the NLRA indicate that the
    Board was designed to serve a reactive role, with its “quasi-
    judicial       power”    being        “restricted           to    [the     enumerated]       unfair
    labor        practices        and     to     cases          in     which        the    choice     of
    representatives          is    doubtful.”              S.       Rep.     No.    73-1184     (1934),
    reprinted in 1 NLRA Leg. Hist. at 1100.                                There is no indication
    in the Act’s legislative history of an intent to allow the Board
    to    impose      duties        upon        employers            proactively;          indeed,    if
    anything, it appears to have been the intent of Congress that
    the Board not be empowered to play such a role.                                    Cf. H.R. Rep.
    No.   74-969      (1935),       reprinted         in        2    NLRA    Leg.     Hist.     at   2932
    (noting that Section 11 does not grant the Board the powers of a
    “roving commission”).
    Of       particular           significance,               Congress        considered       and
    rejected a different notice provision in the NLRA that would
    have required any employer that was a party to a contract that
    conflicted       with     the        NLRA    to        notify      its     employees        of    the
    30
    violation and indicate that the contract would be abrogated.                     S.

    1934), reprinted in 1 NLRA Leg. Hist. at 14; H.R. 8434 73rd
    Cong. § 304(b) (as introduced in House Mar. 1, 1934), reprinted
    in 1 NLRA Leg. Hist. at 1140. 13             In the spring of 1934, as the
    bill was being considered, the Senate Committee on Education and
    Labor expressed “unanimous” agreement for removing the section
    containing that notice provision, 1 NLRA Leg. Hist. at 394-95,
    and       on   May   26,   1934,   a    substitute      bill--with    the     notice
    provision removed--was reported favorably to the Senate.                         S.
    2926, 73rd Cong. § 304(b) (as introduced in Senate on May 26,
    1934), reprinted in 1 NLRA Leg. Hist. 1070-98.                    Although this
    notice provision would have spoken to a different issue than the
    one at hand, the fact that Congress considered the possibility
    of    a    notice    requirement       indicates   at    the   very   least    that
    13
    Along with the proposed requirement that employers notify
    employees of contracts that violated the NLRA, the initial
    versions of the Act made it a ULP to fail to provide that
    notice. S. 2926, 73rd Cong. § 5(5) (as introduced in Senate on
    Feb. 28, 1934), reprinted in 1 NLRA Leg. Hist., at 3; H.R. 8434
    73rd Cong. § 5(5) (as introduced in House Mar. 1, 1934),
    reprinted in 1 NLRA Leg. Hist. at 1130. The fact that the early
    versions of the Act contained a specific, notice-related ULP
    further weakens the Board’s attempt, addressed above, to
    bootstrap authority for the challenged rule from its authority
    to define what constitutes a ULP under Section 8(a)(1).      Had
    Congress intended to require the posting of notices, or make the
    failure to do so be punishable as a ULP, it could have made that
    intent clear in its legislation.
    31
    Congress was aware of the option of authorizing such action and
    chose not to.
    Moreover,      at   the   same   time       as    it    excluded      a     notice
    provision from the NLRA, Congress amended another labor statute,
    the RLA, to include two notice provisions.                   Pub. L. No. 73-442,
    
    48 Stat. 1185
     (1934) (codified as amended at 
    45 U.S.C. § 151
     et
    seq.).      First, Congress amended the RLA to require employers
    subject to that Act to notify employees that, if any contract
    requiring employees to join a union or not join a union had been
    enforced, such contract was no longer binding.                       S. 3266, 73d
    Cong. § 2, Fifth (as introduced Mar. 28, 1934), reprinted in 1
    The Railway Labor Act of 1926: A Legislative History at 742
    (Michael H. Campbell & Edward C. Brewer III eds. 1988) (“RLA
    Leg. Hist.”); H.R. 9861, 73d Cong. § 2, Fifth (as introduced
    Jun. 4, 1934), reprinted in 1 RLA Leg. Hist. at 894.                               This
    provision     was   very   similar    to        the    abrogation      and      notice
    provision included in the original NLRA House and Senate bills.
    A   second    provision    included      in      the    amended      RLA       required
    employers to inform their employees by printed notice of the
    dispute-resolution provisions of the RLA.                   S. 3266, 73d Cong. §
    2, Eighth (as introduced Mar. 28, 1934), reprinted in 1 RLA Leg.
    Hist. at 743-44; H.R. 9861, 73d Cong. § 2, Eighth (as introduced
    Jun. 4, 1934), reprinted in 1 RLA Leg. Hist. at 895-96.                           These
    notice   requirements--which      were     signed      into    law   on    June     21,
    32
    1934--support the proposition that when Congress intends for the
    posting of notices to be required, it provides as much in its
    legislation.
    4.
    Finally,      we     consider          “‘the        history          of        evolving
    congressional regulation in the area.’”                       Brown & Williamson, 153
    F.3d at 162 (quoting Dunn v. Commodity Futures Trading Comm’n,
    
    519 U.S. 465
    ,   475    (1997)).          A        comparison      of   the       NLRA   to
    subsequent labor legislation provides additional evidence that
    Congress did not intend to grant the Board the authority to
    issue a notice-posting requirement.
    In addition to the notice-posting requirement in the RLA,
    Congress has included notice-posting requirements in a number of
    other federal labor laws.           Several labor statutes passed during
    the span of years between 1935 and 1974, during which the NLRA
    was amended three times, provide for the posting of notices.
    See Title VII of the Civil Rights Act of 1964, 42 U.S.C. §
    2000e-10(a); Age Discrimination in Employment Act, 
    29 U.S.C. § 627
    ;   Occupational       Safety    &    Health         Act,   
    29 U.S.C. § 657
    (c).
    Since that time, a number of other labor statutes have been
    passed that have required the posting of notices.                            See Employee
    Polygraph     Protection     Act,       
    29 U.S.C. § 2003
    ;    Americans         with
    Disabilities Act, 
    42 U.S.C. § 12115
    ; Family and Medical Leave
    Act, 
    29 U.S.C. § 2619
    (a).           Even more tellingly, on at least one
    33
    occasion, Congress has amended a labor law to impose a notice-
    posting requirement.               See Veterans’ Benefits Improvement Act of
    2004,       Pub.    L.    No.     108-454,        §    203,     
    118 Stat. 3606
        (2004)
    (codified as amended at 
    38 U.S.C. § 4334
    ).
    The contrast between the roles the NLRA sets forth for the
    NLRB and those that other federal labor statutes prescribe for
    those of its sister agencies with notice-posting authority is of
    particular significance.                As we have discussed, the Board’s core
    functions are reactive ones.                  In contrast, other agencies that
    have     promulgated            notice-posting          requirements         have     proactive
    mandates.           For        instance,    the        EEOC,       which   is    granted       the
    authority to require the posting of notices, 
    29 U.S.C. § 627
    ; 42
    U.S.C.      §   2000e-10(a);         
    42 U.S.C. § 12115
    ,   has      the   power     to
    proactively             file      charges     and           undertake         investigations,
    regardless         of    whether    a     party       files    a    charge,     42    U.S.C.    §§
    2000e-5(b), 2000e-8(a).                 The same is true of the Occupational
    Safety & Health Administration, see 
    29 U.S.C. §§ 657
    , 659, as
    well as the Department of Labor (“DOL”) more generally, see,
    e.g., 
    29 U.S.C. §§ 211
    (a), 216(c), 217, 2005, 2616, 2617. 14

    The Board compares the challenged rule to a DOL notice-
    posting requirement, which it enacted under the Fair Labor
    Standards Act (“FLSA”), despite that statute’s silence as to
    notice-posting.   The Board points us to no authority analyzing
    whether that statute grants the DOL authority to enact a notice-
    posting requirement, and we do not address that issue here. We
    do note that requiring universal employer notice-posting is more
    (Continued)
    34
    Congress’s       continued     exclusion      of   a   notice-posting
    requirement from the NLRA, concomitant with its granting of such
    authority     to     other   agencies,     can     fairly   be    considered
    deliberate.        See Brown & Williamson, 
    529 U.S. at 133
     (2000)
    (“[T]he meaning of one statute may be affected by other Acts,
    particularly    where    Congress   has   spoken   subsequently    and   more
    specifically to the topic at hand.”).            Had Congress intended to
    grant the NLRB the power to require the posting of employee
    rights notices, it could have amended the NLRA to do so.
    congruous with the DOL’s proactive roles in enforcing the FLSA
    than it is with the NLRB’s reactive roles. Unlike the NLRB, the
    DOL has the ability under the FLSA to proactively conduct
    investigations and file enforcement actions.       
    29 U.S.C. §§ 211
    (a), 216(c), 217; see DOL, Enforcement Under the Fair Labor
    Standards   Act,   http://www.dol.gov/elaws/esa/flsa/screen74.asp
    (last visited May 31, 2013).       Furthermore, in enacting its
    notice-posting rule, the DOL was acting pursuant to an enabling
    statute distinct in relevant respects from the NLRA.           In
    particular, the FLSA included a recordkeeping requirement, 
    29 U.S.C. § 211
    (c), and the DOL promulgated its notice-posting
    regulation under its authority to enforce that provision, see 
    29 C.F.R. § 516.4
    .

    For the foregoing reasons, 15 the judgment of the district
    court is
    AFFIRMED.

    Having determined under Chevron’s first step that the
    NLRA unambiguously does not grant authority to the NLRB to
    promulgate the challenged rule, our analysis ends, and we do not
    proceed to Chevron’s second step.
