    LEGG, Chief District Judge:
    In this case we address whether medical evidence offered for
    the sole purpose of disproving liability constitutes “documentary
    evidence” under     § 725.456(b)(1) of the regulations implementing
    the Black Lung Benefits Act.      Relying on the plain language and
    history of that regulation, we conclude that it does. Accordingly,
    we affirm the order of the Benefits Review Board naming petitioner
    Marfork Coal Co. as the responsible operator liable for the payment
    of benefits to respondent Roger L. Weis.         We also affirm the
    Board’s conclusion that Weis’s benefits are payable as of April 1,
    1996.
    I.
    A.
    Coal miners are prone to develop pneumoconiosis, commonly
    known as black lung disease.      The Black Lung Benefits Act (“the
    Act”), 30 U.S.C. § 901 et. seq., provides benefits to coal miners
    who have been totally disabled by pneumoconiosis, and to the
    surviving dependents of miners who die of the disease.
    The Act places liability for the payment of benefits upon the
    “responsible” coal operator.1     Under the regulations implementing
    the Act, the “responsible operator” is usually the coal company

    , 473 (4th Cir.
    2002).

    that most recently employed the miner for at least one year.
    There are a number of grounds, however, upon which the most recent
    employer can avoid liability.          For example, the operator may prove
    that it did not cause, contribute to, or aggravate the miner’s
    pneumoconiosis.3        The operator may establish that it lacks the
    means to pay, in which case the Black Lung Disability Trust Fund
    will pay.4    The operator may also prove that the miner was already
    totally disabled by pneumoconiosis before he was hired.5
    The     Department   of   Labor      (“DOL”)     is     responsible    for   the
    administrative     adjudication      of       black   lung    cases.       Generally
    speaking, the litigation involves three stages.                   A miner or his
    survivor first files a claim with a “district director” from the
    DOL’s    Office    of     Workers’     Compensation           Programs.       After
    investigating the claim, the district director determines whether
    the claimant is eligible for benefits, and, if so, which operator
    is presumptively responsible.6            Any party may appeal the district
    director’s decision to the Office of Administrative Law Judges
    (“OALJ”).7     Thereafter, appeals are to the DOL’s Benefits Review

    Board (“the Board”), and then to the Court of Appeals for the
    circuit in which the miner’s “injury” occurred.8
    In 2000, the DOL revamped its rules to streamline the handling
    of black lung cases.            One thrust of the new rules is to make
    conclusive a district director’s determination of the “responsible
    operator”       liable   for    payments.             If   the       district    director’s
    determination is overturned on appeal, the case is not remanded to
    correct the error.          Instead, benefits are paid by the Black Lung
    Disability Trust Fund (“the Fund”).                   This is the case even if the
    actual responsible operator can be identified.9
    To protect the Fund from unwarranted liability, the rules
    require     the   parties      to   present      to    the   district       director    all
    documentary evidence concerning which operator is liable.10                          Absent
    exceptional circumstances, new documentary evidence pertaining to
    liability may not be thereafter introduced into the record.11                          With
    this background in mind, we turn to the facts.

    Marfork Coal Co. (“Marfork”), which employed him from November 1,
    1994 to August 1, 2006.12
    On July 9, 2002, Weis filed a claim for black lung benefits
    with a DOL district director located in Charleston, West Virginia.
    On August 23, 2002, the district director notified Marfork of
    Weis’s claim and identified Marfork as a potentially liable coal
    operator.13    20 C.F.R. § 725.407.       The regulations required Marfork
    to file a response in which it either accepted or contested that
    identification.       
    Id. § 725.408(a)(1). On
    September 4, 2002,
    Marfork contested liability.14
    The district director ordered a complete pulmonary evaluation
    of Weis.     
    Id. §§ 725.405(b); 725.406(b).
         On September 24, 2002,
    Dr. Manu Patel diagnosed Weis with complicated pneumoconiosis, a
    rare and serious form of black lung disease.15
    12
    Weis retired on August 1, 2006.

    See 20 C.F.R. §§ 725.408; 725.494.

    In support of its position, Marfork had ninety days in which
    to submit evidence concerning its employment of Weis and its status
    as a potentially liable operator. 
    Id. § 725.408(a)(2). Marfork
    did not submit any evidence.
    15
    Coal worker’s pneumoconiosis is customarily classified as
    either “simple” or “complicated.”    Simple pneumoconiosis seldom
    results in significant respiratory impairment.         Complicated
    pneumoconiosis, which is far more serious, involves progressive
    massive fibrosis as a reaction to inhaled coal dust. Complicated
    pneumoconiosis usually causes significant lung impairment and
    breathing difficulties. It may induce death or contribute to death
    by other causes. See Usery v. Turner Elkhorn Mining Co., 
    428 U.S. 1
    , 7 (1976) (footnotes omitted); N. Leroy Lapp, A Lawyer’s Medical
    Guide to Black Lung Litigation,

    . Rev. 721, 729-781
    6
    On January 28, 2003, the district director issued a “Schedule
    for the Submission of Additional Evidence” (“the Schedule”).                
    Id. § 725.410(a). The
    Schedule laid out the district director’s
    preliminary conclusion that Weis was entitled to benefits because
    of his disease.16      It gave Marfork thirty days to accept or contest
    that finding.       J.A. 51.    It also gave the parties sixty days to
    submit additional medical evidence concerning Weis’s entitlement.
    Under      the   regulations,   the    parties    could    submit   entitlement
    evidence either to the district director or thereafter to an ALJ if
    a formal hearing was requested.           J.A. 52.
    In the Schedule, the district director also preliminarily
    designated Marfork as the responsible operator.              J.A. 51.    It gave
    Marfork thirty days to accept or contest this finding.17                J.A. 52.
    It also gave Marfork sixty days in which to submit any “documentary
    evidence relevant to liability.” 
    Id. Such evidence was
    to include
    any   evidence     “relevant    to    whether    another   potentially   liable
    operator should have been designated the responsible operator.”
    J.A. 53.         The Schedule cautioned that “[a]bsent a showing of
    extraordinary circumstances, no documentary evidence relevant to
    (1981).
    16
    A miner with complicated pneumoconiosis is conclusively
    presumed to be totally disabled. 20 C.F.R. §§ 718.203(b); 718.304.
    17
    An operator that fails to respond to the Schedule is deemed
    to have accepted its designation and to have waived its right to
    contest liability in any future proceedings. J.A. 52.
    7
    liability, or testimony of a witness not identified at this stage
    of the proceedings, may be admitted into the record once a case is
    referred to the [OALJ].”      
    Id. On February 11,
      2003,    Marfork    submitted      a     DOL   Operator
    Response form to the district director in which it accepted its
    designation as the responsible operator.             J.A. 65.     It contested,
    however, that Weis was entitled to benefits.            
    Id. Marfork did not
    submit evidence of any kind to the district director.
    Weis, however, did submit additional entitlement evidence to
    the district director.      He proffered two x-ray interpretations by
    Dr. John Parker, who compared x-rays of Weis’s lungs from 1971,
    1974, 1980, 1996, 1999, 2000, and 2003. Parker diagnosed Weis with
    “progressive   massive     fibrosis,”      another    name    for    complicated
    pneumoconiosis.18    Parker noted that the disease had “progressed”
    between 1996 and 2003.      J.A. 14.
    On July 7, 2003, the district director issued a proposed order
    awarding Weis benefits and holding Marfork liable.                Marfork timely
    requested a formal hearing before an ALJ.             On September 18, 2003
    the case was referred to the OALJ.19
    18
    See Lisa Lee Mines v. Director, OWCP, 
    86 F.3d 1358
    , 1359-60
    (4th Cir. 1996) (en banc).
    19
    The district director prepared a list of contested issues for
    the hearing. J.A. 111-113. The issues focused on entitlement.
    “Responsible operator” is not marked as a contested issue.
    8
    In preparation for a hearing before the ALJ, Marfork had Weis
    examined by Dr. Robert Crisalli.            The examination suggested that
    Weis was indeed suffering from complicated pneumoconiosis.                J.A.
    J.A. 354; 364. This revelation prompted Marfork to start “scouring
    hospital admissions, [as well as] State claims, to find out if
    there were any earlier x-rays, which is standard procedure in our
    [Marfork’s attorneys’] office.”             
    Id. As part of
    this search,
    Marfork, in August 2004, discovered a 1992 x-ray of Weis’s lungs
    indicating that Weis was then suffering from the disease, a full
    two years before Marfork hired him.               This medical evidence was
    significant.        If Weis had developed complicated pneumoconiosis
    before Marfork hired him, another operator would be solely liable
    for Weis’s benefits.20
    On October 19, 2004, the ALJ held a hearing.           In addition to
    Weis    and     Marfork,   the   Director    of   the   Office   of   Workers’
    Compensation Programs (the “OWCP Director”) was a party.21 The OWCP
    Director, who acts as trustee for the Black Lung Benefits Fund, is
    responsible for conserving its assets.22                Marfork offered into
    20
    See, e.g., Truitt v. North American Coal Co., 2 BLR 1-199
    (1979), aff’d sub. nom. Director, OWCP v. North American Coal Co.,
    
    626 F.2d 1137
    (3d Cir. 1980).
    21
    Weis and the OWCP Director are the two respondents in              this
    proceeding.   The OWCP Director, who administers the Black               Lung
    Benefits Program, 20 C.F.R. § 701.202(f) (2007), entered the             case
    when Marfork notified him that it contested liability. J.A.              159.
    22
    See, e.g., Truitt, 2 BLR 1-202.
    9
    evidence reports from three doctors who opined, based on the x-ray,
    that Weis was disabled before he came to work for Marfork.23       The
    reports were admitted without objection.
    In light of the new evidence, the ALJ called for post-hearing
    briefs. In his brief, the OWCP Director contended that the medical
    reports should be excluded.    Under 20 C.F.R. § 725.456(b)(1), he
    argued, Marfork was required to have presented all evidence bearing
    on liability to the district director.    Accordingly, Marfork could
    introduce   the   evidence   now   only   by   showing   extraordinary
    circumstances.    Because the x-ray was waiting to be found, no such
    circumstances existed.
    The ALJ agreed.   In a written opinion dated June 27, 2005, he
    excluded Marfork’s evidence, awarded benefits to Weis,24 and held
    Marfork liable.    He further concluded that Marfork had failed to
    develop its exculpatory evidence in a timely fashion.25
    23
    Drs. Wiot, Meyer, and Hippensteel all read the x-ray for the
    company.   All three concluded that the x-ray was positive for
    complicated pneumoconiosis.
    24
    The ALJ determined that Weis’s benefits are payable as of
    April 1996, the date that admissible x-ray evidence showed that
    Weis first suffered from complicated pneumoconiosis.      
    Id. § 725.503(b). 25
          The ALJ made two additional findings that we must briefly
    address. The ALJ found that Marfork could not contest its status
    as a potentially liable operator because it had failed to submit
    evidence within ninety days of receiving notice of Weis’s claim.
    J.A. 230; see 20 C.F.R. § 725.408(b)(1). The ALJ also found that
    Marfork had waived its right to contest its liability under 20
    C.F.R. § 725.412(a)(2) because it had accepted its designation as
    responsible operator before the district director. J.A. 230. The
    10
    On August 19, 2005, Marfork appealed to the Board.               On June
    30, 2006, the Board affirmed in a split decision.               The majority
    held that medical records are included in the term “documentary
    evidence” referenced in § 725.456(b)(1). J.A. 395. The Board also
    affirmed   the   ALJ’s   finding   that    Marfork    had   failed   to   prove
    “extraordinary circumstances.”       J.A. 397.
    Marfork timely filed the instant petition for review. We have
    jurisdiction under 33 U.S.C. § 921(c). For the reasons stated
    below, we deny Marfork’s petition and affirm the decision of the
    Board.
    II.
    On a petition for review of an order of the Board, we
    independently review the record.          Daniels Co., Inc., v. Mitchell,
    
    479 F.3d 321
    , 329 (4th Cir. 2007) (citations omitted).               We review
    the Board’s conclusions of law de novo.         
    Id. We determine whether
    substantial evidence exists to support the ALJ’s findings of fact.
    Consolidation Coal Co. v. Williams, 
    453 F.3d 609
    , 614 (4th Cir.
    2006).26
    Board did not rely on either ground as support for its decision,
    however. Accordingly, neither finding is presently before us. See
    Grigg v. Director, OWCP, 
    28 F.3d 416
    , 418 (4th Cir. 1994) (“We
    confine our review to the grounds upon which the Board based its
    decision.”).
    26
    Substantial evidence is “‘more than a mere scintilla.’”
    Consolidation Coal Co. v. Williams, 
    453 F.3d 609
    , 614 (4th Cir.
    2006) (citations omitted).   Specifically, it is “such relevant
    11
    III.
    This case involves the interpretation of § 725.456(b)(1),
    which governs the admissibility of “documentary evidence pertaining
    to the liability of a potentially liable operator and/or the
    identification of a responsible operator.” Unless submitted to the
    district     director,   such   documentary   evidence   “shall   not    be
    admitted...in the absence of extraordinary circumstances.”              
    Id. The full text
    of the section is as follows:
    Documentary evidence pertaining to the liability of a
    potentially liable operator and/or the identification of
    a responsible operator which was not submitted to the
    district director shall not be admitted into the hearing
    record in the absence of extraordinary circumstances.
    Id.27
    Medical evidence concerning entitlement to benefits is treated
    differently.     
    Id. § 725.456(b)(2). Entitlement
    evidence may be
    offered at either the district director or the ALJ stage.         
    Id. The controversy in
    the instant case arose because the medical opinions
    concerning the 1992 x-ray are pertinent both to Weis’s entitlement
    to benefits and to Marfork’s liability.
    Marfork would read into § 725.456(b)(1) an implied exception
    for medical evidence that pertains to liability.           According to
    evidence as a reasonable mind might accept as adequate to support
    a conclusion.” 
    Id. at 615 (internal
    quotation marks and citations
    omitted).
    27
    Neither the regulations nor the regulatory history found in
    the Federal Register define the term “documentary evidence.”
    12
    Marfork, the regulation would now read, “documentary evidence
    pertaining to...liability, except for medical evidence.”        The OWCP
    Director disagrees, maintaining that the regulation is not only
    clear, but that the DOL intended it to apply to all evidence,
    medical or otherwise, that bears upon liability.
    We agree with the Director.        His interpretation conforms to
    the plain meaning of the regulation, which is unqualified.28          His
    interpretation is also supported by the regulatory history.
    The DOL revised the Act’s regulations in 2000.          One of the
    Department’s   objectives   was   to    simplify   and   streamline   the
    processing of claims at the district director level.        65 Fed. Reg.
    79990.
    An initial draft of the regulations would have required both
    liability and entitlement evidence to be presented to the district
    director.29    
    Id. at 79989. The
    Department observed that this
    28
    Because the black lung regulations are administered by the
    OWCP Director, his interpretation is entitled to “substantial
    deference ‘unless it is plainly erroneous or inconsistent with the
    regulation.’” Mullins Coal Co. v. Director, OWCP, 
    484 U.S. 135
    ,
    159 (1987) (citing Bowles v. Seminole Rock & Sand Co., 
    325 U.S. 410
    , 414 (1945)); see Doss v. Director, OWCP, 
    53 F.3d 654
    , 658 (4th
    Cir. 1995) (citing and applying Mullins). This rule of deference
    applies to an interpretation contained in a brief, including the
    brief that the OWCP Director filed in the instant case. See, e.g.,
    Auer v. Robbins, 
    519 U.S. 452
    , 461-62 (1997). As our discussion
    above makes clear, we find the OWCP Director’s interpretation to be
    neither plainly erroneous nor inconsistent with the regulation.
    29
    The draft regulation would have defined documentary evidence
    as “evidence relevant to operator liability as well as all medical
    evidence relevant to a claimant’s eligibility[.]”

    proposal would end the then-current practice of delaying the
    development of evidence on both issues until the OALJ stage.                      
    Id. Eventually, the DOL
       decided    not    to   require      all   medical
    eligibility evidence to be submitted to the district director. 
    Id. at 79990. The
    DOL did, however, implement its proposal with
    respect to liability evidence.           This decision is clearly stated in
    the Federal Register: “Any such evidence that was not submitted to
    the district director could be submitted to the ALJ only upon a
    showing of extraordinary circumstances.”                
    Id. As the Federal
    Register explains, serious disputes about the
    identity of the responsible operator arise in fewer than ten
    percent of all claims.             
    Id. at 79989; 79991;
    79999-80000.              When
    such disputes do arise, however, the DOL expressly intended to
    resolve them at the district director stage.                   
    Id. The district director
       is   required      to   select     one    and   only   one    responsible
    operator, and he is “permitted to refer a case to the [OALJ] with
    only one designated responsible operator as a party to the claim.”
    
    Id. at 79990. It
    is important that the district director make the right
    decision.      In the event that the operator he              designates is later
    adjudicated not liable, the Fund will pay any benefit award.                      
    Id. There is no
    remand.          
    Id. The Federal Register
    devotes considerable space to explaining
    that   under     the   2000    changes   the     district     director’s       initial
    14
    determination is unassailable even if wrong.                
    Id. “The Department intends
    that once a claim is referred to the [OALJ], the Department
    shall not be able to impose liability for that claim on any
    operator other than the one formally designated by the district
    director,     whether   through     remand    by    the    [ALJ]    or   through    a
    modification of a finally awarded claim.”                 
    Id. For these reasons,
    the DOL obliged operators to develop
    liability evidence at the district director stage, the earliest
    stage of claims processing.             
    Id. at 79999-80000. Operators
    must
    “submit evidence regarding their [own] potential liability for the
    claim.”    
    Id. at 79999. Moreover,
    they must develop and submit “any
    evidence     relevant   to   the    liability      of   another     party.”       
    Id. (emphasis added). This
    arms the district director with sufficient
    information to determine accurately which operator is liable,
    before the case is referred to the OALJ and before all other
    operators are dismissed from the case.              
    Id. at 80000. Given
    this regulatory history, it is implausible to suppose
    that the DOL crafted a system that deprives district directors of
    critical documentary evidence on the issue of liability.                   Disputes
    over   the   identification        of   the   responsible       operator    may    be
    infrequent.     Nonetheless, as the facts of this case demonstrate,
    such disputes do arise and medical evidence can be dispositive.
    Under Marfork’s interpretation, an operator would not be required
    to investigate the medical issues pertinent to liability until
    15
    after the liability Rubicon had been crossed.            The DOL clearly did
    not intend such a result.
    Marfork contends that the Director’s interpretation would
    impose an unreasonable burden on mine owners.             Because liability
    and entitlement evidence can be intertwined, Marfork argues, mine
    operators would be required to develop and present both types of
    evidence to the district director in every case.                    Under the
    Schedule, the operator is allowed only sixty days to present
    liability evidence to the district director. Marfork contends that
    this time period is insufficient because black lung cases can often
    be medically complex.
    This argument is unpersuasive.          In the DOL’s experience, the
    identity of the responsible operator is infrequently in dispute.
    Thus, the operator would be required to present medical evidence to
    the district director in only in a small number of cases.
    As to the time pressure, the sixty day time limit can be
    extended for good cause shown.         20 C.F.R. § 725.423.         Nothing in
    the   record    suggests   that    district   directors    would    deny   mine
    operators      ample   time   to   develop    relevant    medical     evidence
    pertaining to liability.
    IV.
    16
    Marfork next argues that the ALJ committed error by finding
    that    Marfork   had   not   shown   extraordinary     circumstances.   We
    disagree.
    The ALJ carefully analyzed this issue.             As he determined,
    Marfork was on notice that Weis may have developed complicated
    pneumoconiosis     before     1994,   when   he   was   hired.   Complicated
    pneumoconiosis is a progressive disease that develops over time.
    When Marfork hired Weis in 1994, he had been working in coal mines
    for other operators for decades.         When Weis applied for black lung
    benefits, his application, which was sent to Marfork, stated that
    he had previously received state workers’ compensation benefits for
    black lung disease on three occasions.30
    At the district director stage, Weis produced evidence that he
    had been diagnosed with complicated pneumoconiosis.31              Based on
    these and other facts, the ALJ found that Marfork had failed to
    30
    On his application, Weis disclosed that West Virginia had
    awarded him state benefits in 1992, 2000, and 2002. J.A. 2.
    31
    The Schedule contained Dr. Patel’s diagnosis of complicated
    pneumoconiosis. Pursuant to the Schedule, Weis submitted the x-ray
    readings by Drs. Parker and Proto. Dr. Parker’s report explicitly
    stated that his examination of the x-rays dated 1971, 1974, 1980,
    1996, 1999, 2000, and 2003 revealed “advanced dust related disease
    - progressive massive fibrosis,” which was seen in 1996, 1999,
    2000, 2003, and which “has progressed [from] 1996 [to] 2003.” J.A.
    14.
    17
    develop evidence clearly suggesting that another operator might be
    liable.   On appeal, the Board agreed.32
    We find nothing in the record to disturb the ALJ’s conclusion.
    Marfork did not begin investigating the case until the ALJ stage.
    When Dr. Crisalli all but confirmed the diagnosis of complicated
    pneumoconiosis, Marfork belatedly sprang into action, scouring
    hospitals for medical records and ultimately tracking down the
    crucial 1992 x-ray.     J.A. 354; 364.   Extraordinary circumstances
    might exist if the x-ray were hidden or could not have been located
    at the district director stage.   Such is not the case here.   The x-
    ray was waiting to the found.     Accordingly, we affirm the ALJ’s
    finding that Marfork failed to show extraordinary circumstances.
    V.
    Marfork makes two additional arguments, each of which we need
    address only briefly.
    32
    In affirming the ALJ’s decision, the Board correctly noted
    that Marfork never provided any explanation to the ALJ why it had
    failed to develop its evidence at the district director stage.
    J.A. 397.
    18
    A.
    In the Act, Congress stated its intent to impose liability
    only on the responsible operator.33 Based on the 1992 x-ray, it now
    appears     that    Weis    contracted    complicated        pneumoconiosis    while
    employed by another mine operator.34                 In light of this discovery,
    Marfork contends that holding it liable would violate the intent of
    Congress.
    This argument fails because it relies on evidence that was
    properly     excluded      from   the    record.       The    department     has   the
    authority to write regulations governing the orderly litigation of
    black lung cases.          Those regulations presume that the operator who
    last employed the miner for more than a year is responsible.35
    Operators     are    provided     a   fair     chance,      however,   to   introduce
    exculpatory evidence into the record.                 Marfork missed its chance.
    Because     the    medical    evaluations       of    the    1992   x-ray   were   not
    presented to the district director, the evidence Marfork relies
    upon is outside the record.              For purposes of this litigation it
    does not exist. Based on the properly admitted administrative
    33
    Marfork cites § 932 of the Act, which provides that coal mine
    operators are responsible for paying benefits to miners whose death
    or total disability due to black lung disease arose out of
    employment in the operator’s mine.
    34
    Marfork avers that Weis’s employer in 1992, Maben Energy
    Corporation, went bankrupt, and that this is a case where the Fund
    should be liable for benefits. See 20 C.F.R. § 725.495(a)(4).
    35
    20 C.F.R. § 725.495.
    19
    record, Marfork is the responsible operator and the intent of the
    Act has not been violated.
    B.
    Marfork next faults the ALJ for failing to admit the 1992
    medical evidence for the purpose of establishing the date of onset
    of   Weis’s      complicated   pneumoconiosis.        In   order     to   properly
    compensate Weis for his injuries, Marfork contends, a remand is
    necessary to consider the newly discovered evidence. Because the
    ALJ would necessarily consider the 1992 evidence to establish date
    of onset, Marfork asserts that it would be irrational to ignore the
    same evidence for the purpose of imposing liability.
    Weis’s entitlement to benefits, however, is an issue for Weis
    - not Marfork - to raise. Indeed, Weis has attempted to challenge
    the ALJ’s date of onset determination before this Court.36 He is
    precluded from doing so, however, by the doctrine of administrative
    waiver. Although named as a respondent when Marfork appealed the
    ALJ’s        liability   determination    to   the   Board,   Weis    failed   to
    challenge the ALJ’s subsidiary conclusion establishing month of
    onset. Weis filed no brief and declined to appear at oral argument
    before the Board. J.A. 335; 386.              Accordingly, he has waived his
    36
    See Resp’t’s Br. at 2. (“The [Board] erred only in confirming
    the ALJ’s determination that the onset of permanent disability in
    this case was April 1, 1996.”)
    20
    entitlement argument for consideration by this Court.37 See Beth
    Energy Mines v. Cunningham, 104 F. Appx. 881 (4th Cir. 2004)
    (Employer waived statute of limitations objection by failing to
    present it to Board); Armco, Inc. v. Martin, 
    277 F.3d 468
    , 476
    (Declining,    on   grounds    of    administrative   waiver,   to   address
    arguments not presented to Board).
    VI.
    We conclude that the Board correctly determined that medical
    evidence    offered     only    to     disprove    liability    constitutes
    “documentary evidence” within the meaning of § 725.456(b)(1). We
    also conclude that the Board properly affirmed the exclusion of
    Marfork’s     medical   evidence      from   the   administrative    record.
    Accordingly, we affirm the Board’s decision and deny Marfork’s
    petition for review.
    AFFIRMED
    37
    In addition, Weis’s attempt to appeal to this Court is barred
    by the regulations governing proceedings before the Board. Once
    Marfork appealed the ALJ’s liability determination, Weis, as a
    prevailing party, was required to file a cross-appeal in order to
    alter or amend the result of the proceedings before the ALJ. See 20
    C.F.R. § 802.201(a)(2); King v. Tennessee Consolidated Coal Co., 6
    BLR 1-87 (Ben.Rev.Bd. 1983)(Cross-appeal required where “prevailing
    party” seeks to alter judgment below); accord Malcomb v. Island
    Creek Coal Co., 
    15 F.3d 364
    , 369 (Argument made without cross-
    appeal must support ALJ’s decision, but not necessarily his
    reasoning). Although Weis’s entitlement argument would have
    precisely this effect, he declined file a cross-appeal to the
    Board. Having failed to comply with the Board’s regulations, Weis
    is therefore precluded from objecting to the ALJ’s conclusion
    establishing date of onset.
    21
    WILLIAMS, Chief Judge, dissenting:
    The regulations governing applications for benefits under the
    Federal Coal Mine Health and Safety Act of 1969, 30 U.S.C.A. §§
    901-945 (West 2007) (“the Black Lung Benefits Act” or “the Act”),
    set   forth   detailed   requirements     governing   the    development     of
    evidence at each stage of the administrative process through which
    such claims are adjudicated.        Among these provisions is 20 C.F.R.
    § 725.456(b)(1), which provides as follows:
    Documentary evidence pertaining to the liability of a
    potentially liable operator and/or the identification of
    a responsible operator which was not submitted to the
    district director shall not be admitted into the hearing
    record in the absence of extraordinary circumstances.
    Medical evidence in excess of the limitations contained
    in § 725.414 shall not be admitted into the hearing
    record in the absence of good cause.
    20 C.F.R. § 725.456(b)(1) (2007).           The majority arrives at its
    interpretation     of    §    725.456(b)(1)    by     taking     the   phrase
    “[d]ocumentary evidence pertaining to [] liability” out of context
    and concluding that, when viewed in isolation, the regulation’s
    reference to “[d]ocumentary evidence pertaining to [] liability” is
    “unqualified,”    ante   at   12,   and   therefore   must     encompass     all
    evidence submitted for the purpose of proving or disproving an
    operator’s liability that is documentary in form.              I disagree.
    For the reasons that follow, I agree with Marfork Coal Co.
    (“Marfork”) that the language and structure of § 725.456(b) (as
    well as the “regulatory history” on which the majority relies)
    reveal that the regulation delineates two distinct categories of
    22
    documentary evidence -- “medical evidence” and “evidence pertaining
    to the liability of a potentially liable operator and/or the
    identification of a responsible operator,” which the Department of
    Labor (“DOL”) did not anticipate would overlap.        Moreover, cross
    references between the regulations make clear that the category of
    evidence pertaining to liability in § 725.456(b) encompasses only
    that evidence which 20 C.F.R. §§ 725.408(b) and 725.414(b) (2007)
    authorize parties to submit to the district director.           I would
    therefore conclude that, because the phrase “[d]ocumentary evidence
    pertaining to [] liability” in § 725.456(b) references a narrow and
    specific   category   of   evidence    identified   elsewhere   in   the
    regulations, the Benefits Review Board (“BRB”) erred in construing
    the phrase as broadly encompassing any and all documentary evidence
    used to disprove liability.1   Accordingly, I respectfully dissent.
    1
    The majority states that an operator may avoid liability by,
    among other things, “prov[ing] that it did not cause, contribute
    to, or aggravate the miner’s pneumoconiosis” or “prov[ing] that the
    miner was already totally disabled by pneumoconiosis before he was
    hired.” Ante at 3. These alternatives, however, are one and the
    same.    Demonstrating that a miner was totally disabled from
    pneumoconiosis prior to his employment with the operator is simply
    one way of proving that the operator did not cause or contribute to
    the miner’s total disability. See, e.g., Truitt v. N. Am. Coal
    Co., 2 Black Lung Rep. 1-199, 1-204/05 (1979) (reasoning that
    because a miner with complicated pneumoconiosis is irrebutably
    presumed to be totally disabled due to pneumoconiosis, coal mine
    employment subsequent to the development of the complicated
    pneumoconiosis could not contribute to the disability).
    23
    I.
    We review the BRB’s decision for errors of law and to ensure
    that the BRB adhered to its statutory standard of review.      Dehue
    Coal Co. v. Ballard, 
    65 F.3d 1189
    , 1193 (4th Cir. 1995).    “To that
    end, we undertake an independent review of the record, as in the
    place of the BRB, to determine whether the ALJ’s factual findings
    were based upon substantial evidence in the record.”        
    Id. We review the
    BRB’s legal conclusions de novo.   
    Id. Because the Director
    of the Office of Workers’ Compensation
    (“the Director”) administers the regulations implementing the Black
    Lung Benefits Act, we accord his interpretation of an ambiguous
    regulatory provision “substantial deference unless it is plainly
    erroneous or inconsistent with the regulation.”     Mullins Coal Co.
    v. Director, O.W.C.P., 
    484 U.S. 135
    , 159 (1987) (internal quotation
    marks omitted).   In this case, however, the majority relies on the
    “plain language and history of the regulation,” ante at 2, in
    embracing the Director’s view, not deference to its proponent.    In
    addition, the Director himself has asserted that because “the
    regulatory language is clear and unambiguous,” no deference is due.
    (J.A. at 355.)    Although I read the regulations differently than
    the Director, I agree that their meaning is plain.    Accordingly, I
    too would accord no deference to the Director’s interpretation.
    24
    A.
    As with the interpretation of statutes, our interpretation of
    federal regulations begins with their language.          See Robinson v.
    Shell Oil Co., 
    519 U.S. 337
    , 340 (1997) (“Our first step in
    interpreting a statute is to determine whether the language at
    issue has a plain and unambiguous meaning with regard to the
    particular dispute in the case.”).           Questions concerning the
    plainness or the ambiguity of the statutory language are resolved
    “by reference to the language itself, the specific context in which
    that language is used, and the broader context of the statute as a
    whole.”    
    Id. at 341; see
    also Ayes v. U.S. Dept. of Veterans
    Affairs, 
    473 F.3d 104
    , 108 (4th Cir. 2006) (“Of course, in looking
    to the plain meaning, we must consider the context in which the
    statutory words are used because we do not construe statutory
    phrases in isolation; we read statutes as a whole.” (internal
    quotation marks omitted)).
    The language and structure of § 725.456(b) make clear that §
    725.456(b)(1)’s reference to “[d]ocumentary evidence pertaining to
    []   liability”   does   not   encompass   medical   evidence.   Section
    725.456(b)(1) provides that:
    Documentary evidence pertaining to the liability of a
    potentially liable operator and/or the identification of
    a responsible operator which was not submitted to the
    district director shall not be admitted into the hearing
    record in the absence of extraordinary circumstances.
    Medical evidence in excess of the limitations contained
    in § 725.414 shall not be admitted into the hearing
    record in the absence of good cause.
    25
    20 C.F.R. § 725.456(b)(1).             Thus, § 725.456(b)(1) sets forth
    separate requirements for “[d]ocumentary evidence pertaining to
    the   liability      of   a    potentially     liable   operator     and/or     the
    identification of a responsible operator” and “[m]edical evidence.”
    
    Id. Section 725.456(b)(2), in
    contrast, provides that
    [s]ubject to the limitations in paragraph (b)(1) of this
    section, any other documentary material, including
    medical reports, which was not submitted to the district
    director, may be received in evidence subject to the
    objection of any party, if such evidence is sent to all
    other parties at least 20 days before a hearing is held
    in connection with the claim.
    
    Id. § 725.456(b)(2) (emphasis
    added).            In § 725.456(b)(2), the DOL
    did   not    leave   it   to    the   reader    to   assume   that   “any     other
    documentary material” could include medical reports. Instead, that
    subsection explicitly states that the reference to documentary
    material included medical reports.             Applying the rule of statutory
    construction expressio unius est exclusio alterius (“the expression
    of one thing implies the exclusion of another”), the omission of a
    reference to medical evidence in § 725.456(b)(1)’s pronouncement
    regarding     “[d]ocumentary      evidence     pertaining     to   liability”    is
    properly understood as an exclusion of that evidence.                  See 
    Ayes, 473 F.3d at 110-11
    (“The time-honored maxim expressio unius est
    exclusio alterius . . . applies with great force here.”); 2A Norman
    J. Singer, Sutherland on Statutory Construction § 47.23 (6th ed.
    2000).      Thus, given the language of § 725.456(b)(2), it is clear
    26
    that the phrase “[d]ocumentary evidence pertaining to [] liability”
    in § 725.456(b)(1) does not encompass medical evidence.
    B.
    Moreover,   even   absent   the   explicit   language   in    §
    725.456(b)(2),   the interplay among the regulations governing the
    adjudication of claims for benefits under the Black Lung Benefits
    Act further demonstrates that the reference to “[d]ocumentary
    evidence pertaining to [] liability” in § 725.456(b)(1) is not an
    unqualified phrase encompassing all evidence having any bearing on
    an operator’s liability.   As explained below, that phrase merely
    references specific evidence identified elsewhere in the regulatory
    scheme.
    The DOL’s regulations detail the mechanism through which an
    operator’s liability and a claimant’s entitlement to benefits are
    established. With regard to liability, the district director first
    uses the information provided in an applicant’s claim form to
    identify one or more potentially liable operators and sends those
    operators a notice of claim.     20 C.F.R. § 725.407 (2007).      An
    operator receiving such a notice has thirty days within which to
    file a response “indicating its intent to accept or contest its
    identification as a potentially liable operator.”     20 C.F.R. §
    725.408(a)(1) (2007). If the operator contests its identification,
    it must, “on a form supplied by the district director, state the
    precise nature of its disagreement by admitting or denying each of
    27
    [the five] assertions” listed in 20 C.F.R. § 725.408(a)(2).     20
    C.F.R. § 725.408(a)(2).   The five assertions in § 725.408(a)(2)
    relate only to the operator’s employment of the claimant and
    ability to make payments.2   The operator “may submit documentary
    evidence in support of its position” within 90 days of the date on
    which it received the notice of claim.   20 C.F.R. § 725.408(b)(1).
    An operator that does not submit documentary evidence relevant to
    the five assertions in § 725.408(a)(2) within the 90-day period is
    precluded from introducing the evidence at a later date. 20 C.F.R.
    § 725.408(b)(2) (“No documentary evidence relevant to the grounds
    set forth in [§ 725.408(a)(2)] may be admitted in any further
    proceedings unless it is submitted within the time limits set forth
    in this section.”).
    After receiving the responses and evidence submitted pursuant
    to § 725.408, the district director designates a “responsible
    operator” liable for the payment of benefits and issues a schedule
    2
    Specifically, the five assertions that the operator must
    admit or deny are:
    (I) That the named operator was an operator for any
    period after June 30, 1973;
    (ii) That the operator employed the miner as a miner for
    a cumulative period of not less than one year;
    (iii) That the miner was exposed to coal mine dust while
    working for the operator;
    (iv) That the miner’s employment with the operator
    included at least one working day after December 31,
    1969; and
    (v) That the operator is capable of assuming liability
    for the payment of benefits.
    20 C.F.R. § 725.408(a)(2) (2007).
    28
    for the submission of additional evidence.                     20 C.F.R. § 725.410
    (2007).    The schedule must allow the parties “not less than sixty
    days within which to submit additional evidence, including evidence
    . . . relevant to the liability of the designated responsible
    operator.” 20 C.F.R. § 725.410(b). This additional evidence must,
    however, “meet the requirements set forth in § 725.414 in order to
    be admitted into the record.”            20 C.F.R. § 725.410(b).
    Section     725.414,     in    turn,        contains   separate     subsections
    entitled “medical evidence” and “evidence pertaining to liability.”
    See   20   C.F.R.   §   725.414(a),(b).3              The    subsection    addressing
    evidence pertaining to liability, § 725.414(b), provides that
    “[e]xcept    as     provided        by   §    725.408(b)(2),       the     designated
    responsible operator may submit evidence to demonstrate that it is
    not the potentially liable operator that most recently employed the
    claimant.”      20 C.F.R. § 725.414(b)(1).              Thus, the only “evidence
    pertaining to liability” that § 725.414 permits a designated
    responsible operator to submit to the district director is evidence
    that (1) demonstrates that it is not the potentially responsible
    operator that most recently employed the claimant, and (2) does not
    go to the five assertions in § 725.408(a)(2).                     See 20 C.F.R. §§
    725.408(b)(2), 725.414(b)(1).            Section 725.414 does not authorize

    Section 725.414 distinguishes between documentary evidence
    and testimony. Section 725.414(a) & (b) apply only to documentary
    evidence. Section 725.414(c) addresses testimony. See 20 C.F.R.
    § 725.414 (2007).
    29
    the designated responsible operator to submit any other type of
    evidence pertaining to liability.
    Pursuant to § 725.414(d), parties must submit the “evidence
    pertaining to liability” detailed in § 725.414(b) within the time
    period allotted in the schedule set by the district director; it
    cannot be introduced into the record at a later stage of the
    proceedings.   See 20 C.F.R. § 725.414(d).   Section 725.414(d) does
    not apply to medical evidence submitted in accordance with §
    725.414(a).    In   addition,   §   725.414(d)’s   limitation    on    the
    submission of evidence pertaining to liability is not absolute --
    it excepts evidence admissible under §§ 725.456 and 725.310(b). 20
    C.F.R. § 725.414(d) (“Except to the extent permitted by § 725.456
    and § 725.310(b), the limitations set forth in this section shall
    apply to all proceedings conducted with respect to a claim, and no
    documentary evidence pertaining to liability shall be admitted in
    any further proceeding conducted with respect to a claim unless it
    is submitted to the district director in accordance with this
    section.”).4
    Accordingly,   evidence    pertaining   to    liability    that   is
    admissible under § 725.414(b) may be submitted after a case has
    4
    Section 725.310(b) addresses the submission of additional
    medical evidence in modification proceedings (proceedings in which
    the district director may reconsider the terms of an award or the
    denial of benefits), and has no applicability to the introduction
    of liability evidence while a claim is before the ALJ.      See 20
    C.F.R. § 725.310(b) (2007).
    30
    been transferred from the district director to the Office of
    Administrative     Law    Judges    (ALJs)    only     if    it    falls      within   an
    exception   contained      in   §   725.456.       One      such   exception      is    §
    725.456(b)(1), the provision discussed in Part A, which allows the
    admission   into    the    hearing    record      of   “[d]ocumentary          evidence
    pertaining to liability” that was not submitted to the district
    director    in     “extraordinary       circumstances.”              20       C.F.R.   §
    725.456(b)(1) (stating that “[d]ocumentary evidence pertaining to
    the liability of a potentially liable operator which was not
    submitted to the district director shall not be admitted into the
    hearing record in the absence of extraordinary circumstances”).
    Thus, contrary to the majority’s view, § 725.456(b)(1) does
    not represent an independent requirement governing a category of
    “evidence pertaining to [] liability” broader than or otherwise
    different from the “evidence pertaining to liability” described in
    §§   725.408(b)    and    725.414(b).        It   simply     places       a   qualified
    limitation on the parties’ ability to introduce to the ALJ evidence
    that they could have submitted to the district director pursuant to
    §§ 725.408(b) and 725.414(b).
    C.
    Contrary to the majority’s assertion, the comments to the
    regulations governing the adjudication of claims for Black Lung
    benefits do not countenance an expansive interpretation of §
    725.456(b)(1).      To the contrary, an examination of these comments
    31
    further demonstrates that the DOL intended to allow potentially
    liable operators to defer the development of medical evidence until
    after a case was referred to the Office of ALJs.
    The majority correctly notes that when the DOL revised the
    regulations in 2000, it sought to streamline the processing of
    claims.   Regulations Implementing the Federal Coal Mine Health and
    Safety Act of 1969, as Amended, 65 Fed. Reg. 79920, 79990 (Dec. 20,
    2000). To this end, the revised regulations prohibit remand to the
    district director for the designation of a new responsible operator
    in the event that the ALJ determines the district director erred in
    its original selection.        
    Id. at 79986. This
    restriction reduces
    delay in the adjudication of claims but also “places the risk that
    the district director has not named the proper operator on the
    Black Lung Disability Trust Fund [(the “Fund”)].”             
    Id. The Director argues
    that the DOL proved willing to place this
    risk on the Fund because the DOL believed that the regulations
    governing    evidence   pertaining    to   liability      would   provide   the
    district director with the information necessary to designate the
    correct responsible operator and avoid subjecting the Fund to
    unwarranted liability.        The majority accepts this contention, and
    reads the Federal Register commentary as evincing the DOL’s belief
    that,   in   revising   the    regulations,    it   had   provided   for    the
    submission of all evidence relevant to liability to the district
    director.    That the DOL sought to provide the district director
    32
    with       all   of    the   information    necessary     to   correctly      identify
    responsible operators, however, does not mean that the regulations
    the DOL enacted in fact accomplished this goal.
    In support of its view, the majority seizes on fragments of
    the    commentary        stating    that    operators     must   “submit      evidence
    regarding their potential liability for the claim” and that the
    regulations require the “submission of any evidence relevant to the
    liability of another party during the district director's claims
    processing.”           
    Id. at 79999. To
    be sure, the comments do indicate
    that “the evidentiary limitations of §§ 725.408 and 725.414 are
    designed         to    provide   the   district     director     with   all    of   the
    documentary           evidence   relevant     to    the    determination      of    the
    responsible operator liable for the payment of benefits.”                      
    Id. at 79976.5 The
    DOL’s belief that it had identified all of the
    documentary           evidence   relevant   to     an   operator’s   liability      and
    provided for its submission to the district director pursuant to §§
    5
    The comments, like the regulations, recognize two types of
    evidence relevant to liability “(1) [d]ocumentary evidence relevant
    to an operator’s identification as a potentially liable operator,
    governed by § 725.408; and (2) documentary evidence relevant to the
    identity of the responsible operator, governed by § 725.414 and
    725.456(b)(1).”   Regulations Implementing the Federal Coal Mine
    Health and Safety Act of 1969, as Amended, 65 Fed. Reg. 79920,
    79976 (Dec. 20, 2000). The comments also describe the two types of
    evidence. With regard to the documentary evidence relevant to the
    identity of the responsible operator, they state that, “[u]nder §
    725.414, an operator may submit documentary evidence to prove that
    a company that more recently employed the miner should be the
    responsible operator.” 
    Id. They do not,
    however, reference any
    other evidence as potentially relevant to liability.
    33
    725.408 and 725.414, however, has no bearing on whether § 725.456
    properly can be construed as creating an independent requirement
    that operators submit medical evidence bearing on liability to the
    district director.6
    Moreover, the commentary explicitly states that the revised
    regulations “permit parties to maintain their current practice of
    deferring the development of medical evidence until after a case
    had been referred to the Office of Administrative Law Judges.” 
    Id. at 79984. The
    DOL addressed the anticipated costs of compliance
    with the revised regulations in some detail, explaining that “while
    potentially    liable   operators   [would]   be   required   to   develop
    evidence relevant to their liability while claims [were] pending
    before district directors, they [would] no longer need to expend
    money on the development of medical evidence in those cases . . .
    that do not proceed beyond the district director level.”             
    Id. Accordingly, “in the
    small number of cases in which the Department
    [did] not name the miner’s most recent employer as the responsible
    6
    The DOL may have overlooked this possibility because cases in
    which medical evidence is relevant to the identification of the
    responsible operator are rare. Medical evidence is irrelevant in
    cases involving simple pneumoconiosis, and these cases account for
    the majority of claims under the Act. And, as the Director has
    acknowledged, complicated pneumoconiosis cases in which liability
    is disputed are rare. Rarer still are cases in which a miner is
    presumed totally disabled from complicated pneumoconiosis but works
    for several more years before filing for benefits. Moreover, even
    in these unusual circumstances, the claimant would ordinarily seek
    out evidence relevant to the onset date of his complicated
    pneumoconiosis in order to obtain the full amount of benefits
    available under the Act.
    34
    operator,” the earlier employer might “incur additional costs in
    attempting to establish that a more recent employer should be held
    liable for the payment of benefits.”                    
    Id. The DOL believed,
    however, that “[i]n comparison to the costs of developing medical
    evidence . . . the additional costs imposed by the regulations
    [would] not be significant.”            
    Id. Thus, the comments
    reveal that
    the DOL intended the revised regulations to allow operators to
    defer the development of medical evidence until the case reached
    the ALJ.
    D.
    In sum, the language and structure of 20 C.F.R. § 725.456(b)
    itself,    the    interplay      among    the    regulations        governing   the
    development      of   evidence    at    each    stage    of   the   administrative
    process, and the Federal Register comments to the regulations make
    clear that § 725.456(b) differentiates between “medical evidence”
    and “evidence pertaining to liability.”             These sources also reveal
    that whether a particular piece of documentary evidence constitutes
    medical evidence or evidence pertaining to liability depends on
    what the evidence is, not the purpose for which it is offered.
    Only evidence relevant to the five assertions in § 725.408(a)(2)
    and evidence demonstrating that an operator was not the potentially
    liable     operator     that     most    recently       employed    the   claimant
    constitutes “evidence pertaining to liability” within the meaning
    of §§ 725.414(b)&(d) and 725.456(b)(1).             The evidence that Marfork
    35
    sought to introduce to the ALJ -- interpretations of a 1992 x-ray
    demonstrating that Weis suffered from complicated pneumoconiosis
    prior to his employment with Marfork -- was neither.          Accordingly,
    the BRB erred in concluding that § 725.456(b)(1) precluded the
    introduction into the record of the 1992 x-ray interpretations.7
    II.
    In sum, I believe that the BRB erred in concluding that
    medical   evidence    may   constitute      “evidence   pertaining       to   []
    liability”   within   the   meaning    of   §   725.456(b)(1).       I    would
    7
    I also wish to note that, even were I to agree with my
    colleagues’ interpretation of § 725.456(b), I would be inclined to
    find that submission of the 1992 x-ray before the Administrative
    Law Judge (“ALJ”) was proper because § 725.456(b)(1) permits
    submission of documentary evidence to the ALJ in extraordinary
    circumstances. Given that the comments to the regulations indicate
    that the regulations “permit parties to maintain their current
    practice of deferring the development of medical evidence until
    after a case had been referred to the Office of Administrative Law
    Judges,” 65 Fed. Reg. at 79984, and promise that the regulations
    will not be a trap for the unwary litigant, see Fed. Reg. at 79986
    (rejecting such criticism because “the nature of the evidence
    required . . . and the time limits for submitting that evidence,
    are clearly set forth in the regulations, and will be communicated
    to potentially liable operators who are notified of a claim by the
    district director”), it seems unduly harsh to presume Marfork had
    notice that it needed to present the 1992 x-ray to the district
    director.
    Moreover, in this case, permitting Marfork to introduce the
    1992 x-ray would not have worked prejudice upon the Fund.      The
    record instead reveals that Weis’s employer in 1992, Maben Energy
    Co., went bankrupt while self-insured and that its liability
    transferred to the Fund. See C.F.R. § 725.495(a)(4)(2007). Thus,
    the Fund would have been liable in any event and, if anything, is
    now receiving a windfall in that a demonstrably innocent operator
    is left to provide Weis’s benefits.
    36
    therefore reverse the BRB’s determination that the ALJ properly
    ignored the 1992 x-ray interpretations in adjudicating Marfork’s
    liability for Weis’s Black Lung benefits and remand for further
    proceedings.   Accordingly, I respectfully dissent.
    37
