    OPINION OF THE COURT
    _____________
    FUENTES, Circuit Judge:
    Petitioner Shamokin Filler Company, Inc., operates a
    coal preparation facility in Shamokin, Pennsylvania that has
    been regulated by the Federal Mine Safety and Health
    Administration (“MSHA”) since 1977. After a change in
    ownership in 2009, the new owners challenged MSHA’s
    jurisdiction over the Shamokin facility, contending that the
    2
    Occupational Safety and Health Administration (“OSHA”),
    not MSHA, should oversee it.1 The Secretary of Labor, along
    with an Administrative Law Judge for the Federal Mine
    Safety and Health Review Commission, and the same
    Commission’s appellate body, all disagreed and concluded
    that because Shamokin was engaged in the “work of
    preparing the coal,” as defined in the Federal Mine Safety and
    Health Act of 1977 (the “Mine Act”), 30 U.S.C. § 802(i),
    MSHA’s assertion of jurisdiction was proper. Shamokin
    petitions for review of the Commission’s final order, arguing
    that its plant does not engage in the “work of preparing the
    coal” because it makes its 100% coal products out of already
    processed coal.
    Shamokin’s interpretation of the statute lacks any basis
    in the text of the Mine Act, and we decline to adopt it.
    Shamokin also requests reversal of an evidentiary
    determination       excluding      evidence    of     MSHA’s
    non-jurisdiction over other plants. We find this evidentiary
    challenge to be without merit. For the reasons that follow, we
    will deny the petition for review.
    I. BACKGROUND2
    1
    Presumably the new owners desired to avoid the more
    stringent requirements imposed by MSHA regulations and the
    Federal Mine Safety and Health Act of 1977, 30 U.S.C. § 801
    et seq. As discussed in more detail below, MSHA, rather than
    OSHA, has much stricter oversight requirements including
    regarding respirable coal dust standards.
    2
    We have jurisdiction over this appeal under 30
    U.S.C. § 816(a). The Administrative Law Judge’s (“ALJ”)
    3
    A. Legal and Administrative Framework
    The U.S. Department of Labor oversees, in relevant
    part, two agencies devoted to workplace safety and worker
    health: OSHA and MSHA. OSHA administers the
    Occupational Health and Safety Act of 1970 (the “OSH Act”)
    and regulates workplace safety and worker health unless
    Congress has conferred jurisdiction on another agency in an
    industry-specific statute. See 29 U.S.C. § 653(b)(1). In this
    case, OSHA and the OSH Act govern Shamokin’s plant
    unless MSHA, administering the Mine Act, governs instead.
    The difference in jurisdiction results in a difference in
    oversight. MSHA’s regulatory framework is more specific
    and extensive than OSHA’s in regulating safety and health
    hazards associated with the handling of coal, particularly with
    final decision and order, entered on October 18, 2012, was
    not directed for review by the Mine Commission and by law
    became a final order of the Mine Commission on November
    26, 2012. We review the Mine Commission’s legal
    conclusions de novo. See Reich v. D.M. Sabia Co., 
    90 F.3d 854
    , 860 (3d Cir. 1996). We review evidentiary rulings for
    abuse of discretion. See Mach Min., LLC v. Sec’y of Labor,
    Mine Safety & Health Admin., 
    728 F.3d 643
    , 659 (7th Cir.
    2013); cf. Gunderson v. U.S. Dep’t of Labor, 
    601 F.3d 1013
    ,
    1021 (10th Cir. 2010) (reviewing evidentiary decisions of an
    ALJ of the Department of Labor’s Benefits Review Board
    under an abuse of discretion standard); R & B Transp., LLC v.
    U.S. Dep’t of Labor, Admin. Review Bd., 
    618 F.3d 37
    , 44 (1st
    Cir. 2010) (same as to decisions of an ALJ of the Department
    of Labor’s Administrative Review Board).

    regard to workers’ exposure to respirable coal dust. Compare
    30 C.F.R. Part 71 with 29 C.F.R. Part 1910, Subpart Z.
    Because of the dangers inherent in mining, Congress also
    gave the Secretary more rigorous enforcement mechanisms
    under the Mine Act than under the OSH Act. For example,
    the Mine Act, unlike the OSH Act, requires two inspections
    per year for surface mines, permits inspections to be
    conducted without a warrant, and in specified circumstances
    authorizes inspectors to issue orders requiring withdrawal of
    miners from the mine. See 30 U.S.C. §§ 813(a), 814(d),
    814(e), 817(a); Donovan v. Dewey, 
    452 U.S. 594
    , 606 (1981);
    RNS Servs., Inc. v. Sec'y of Labor, Mine Safety & Health
    Admin. (MSHA), 
    115 F.3d 182
    , 187 (3d Cir. 1997).
    In order to determine whether MSHA and the Mine
    Act govern, we must decide whether the facility to be
    regulated is a “coal or other mine, the products of which enter
    commerce, or the operations or products of which affect
    commerce.” 30 U.S.C. § 803; see RNS Servs., 
    Inc., 115 F.3d at 183
    . In relevant part, a “coal or other mine” under the Mine
    Act includes “lands, . . . facilities, equipment, machines,
    tools, or other property, . . . used in, or to be used in, . . . the
    work of preparing coal . . . and includes custom coal
    preparation facilities.” 30 U.S.C. § 802(h)(1)-(h)(2). We have
    found this provision to be “so expansively worded as to
    indicate an intention on the part of Congress to authorize the
    Secretary to assert jurisdiction over any lands integral to the
    process of preparing coal for its ultimate consumer.” RNS
    Servs., 
    Inc., 115 F.3d at 186
    (emphasis added). The Mine Act
    defines “the work of preparing the coal” as “the breaking,
    crushing, sizing, cleaning, washing, drying, mixing, storing,
    and loading of bituminous coal, lignite, or anthracite, and
    5
    such other work of preparing such coal as is usually done by
    the operator of the coal mine.” 30 U.S.C. § 802(i).
    We employ a “functional analysis” in assessing
    whether MSHA has jurisdiction, under which we give the
    “broadest possible scope to [M]ine Act coverage.” Pa. Elec.
    Co. v. Fed. Mine Safety & Health Review Comm’n
    (“Penelec”), 
    969 F.2d 1501
    , 1503 (3d Cir. 1992) (quotation
    marks omitted). What matters most is how the company uses
    the coal:
    Turning to the case law, in [Penelec], we held
    that “the delivery of raw coal to a coal
    processing facility is an activity within the Mine
    Act, but not the delivery of completely
    processed coal to the ultimate consumer.” 
    969 F.2d 1501
    [at 1504] (citing Stroh v. Director,
    Office of Workers’ Comp. Progs., 
    810 F.2d 61
    ,
    64 (3d Cir. 1987)). See also Hanna v. Director,
    Office of Workers’ Comp. Progs., 
    860 F.2d 88
    ,
    92-93 (3d Cir.1988). In Stroh, we found that
    “shovel[ing coal] into [a] truck, and haul[ing] it
    to independently owned coal processing plants”
    was integral to the work of preparing the coal.
    [810 F.2d] at 62. We further noted that the
    loaded coal’s subsequent transportation over
    public roads did not alter its status as an activity
    that is part of the work of preparing the coal. 
    Id. at 65.
    Penelec applied a functional analysis, wherein
    the propriety of Mine Act jurisdiction is
    determined by the nature of the functions that
    6
    occur at a site. That analysis has its roots in
    Wisor v. Director, Office of Workers’ Comp.
    Progs., 
    748 F.2d 176
    , 178 (3d Cir.1984), was
    applied in 
    Stroh, 810 F.2d at 64
    , and has been
    adopted by the Fourth Circuit. See United
    Energy Servs., Inc. v. Federal Mine Safety &
    Health Admin.,

    B. Procedural History
    Between 1977 and 2009, MSHA treated Shamokin’s
    facility, operated by another owner, as a mine and inspected it
    for compliance with the Mine Act. In 2009, Shamokin
    changed ownership. The current owners (children of the
    former owners) wrote to the Secretary of Labor requesting
    that MSHA relinquish jurisdiction over the plant. The
    Secretary refused. Between 2009 and 2011, the Secretary,
    through MSHA, issued a number of citations against
    Shamokin for violations of the Mine Act that MSHA
    inspectors found at Shamokin’s plant. Among the most
    serious of these citations were numerous violations of
    MSHA’s respirable dust standards.
    Shamokin contested the citations in front of an ALJ of
    the Federal Mine Safety and Health Review Commission.
    Shamokin stipulated that it was liable for the violations and
    associated penalties to the extent that MSHA appropriately
    exercised jurisdiction over the plant. However, Shamokin
    objected to MSHA’s jurisdiction, on the grounds that it was
    not operating a “coal or other mine,” but instead was mainly
    7
    engaged in the manufacture of products made out of coal
    rather than the preparation of anthracite coal. After an ALJ
    found that MSHA had jurisdiction, Shamokin appealed to the
    Mine Commission’s appellate body, which affirmed the ALJ.
    C. Factual Findings of the Mine Commission
    The facts as found by the Mine Commission are
    conclusive as Shamokin mounts no argument to show that
    they are not supported by substantial evidence. See 30
    U.S.C. § 816(a). The ALJ specifically found that, “the Carbon
    Plant is a custom coal preparation facility that stores, sizes,
    dries and loads coal to make it suitable for subsequent
    industrial use.” App. at A25. The ALJ also determined
    Shamokin’s key witness “offered contradictory, inconsistent,
    and suspect testimony.” 
    Id. Specifically, there
    was “an
    attempt by the owners to obstruct the amount of coal used by
    the Carbon Plant, the percentage of coal versus non-mined
    materials, and the actual nature and extent of its coal versus
    non-coal operations.” 
    Id. The ALJ
    determined that
    Shamokin’s assertion that it was principally engaged in
    manufacturing coal products, rather than coal processing, was
    belied by the evidence: “over 6,000 tons of [Shamokin’s]
    product, ‘carb-o-cite,’ made of 100% anthracite coal, was
    sold in 2009, as compared to only a few tons of multiple
    products containing no coal or coal mixtures. . . . This Court
    noted that neither inspector . . . observed any mixing of coal
    with non-coal materials at the plant.” 
    Id. at A26.
    The ALJ
    concluded that “[Shamokin] is storing large amounts of coal,
    screening it to remove impurities and ensure size quality,
    drying it, and loading it in bags appropriately sized to be sold
    in the stream of commerce.” 
    Id. at A28.
    The Mine
    8
    Commission’s appellate body affirmed the ALJ’s decision as
    supported by “substantial evidence.” 
    Id. at A36.
    D. Conclusions of Law of the Mine Commission
    The ALJ determined that “[t]he fact that [Shamokin] is
    customizing the formulas to meet industry and customer
    specifications only strengthens the Secretary’s position that
    [Shamokin] is operating a custom coal preparation facility
    and should, therefore, continue to be covered under MSHA’s
    jurisdiction.” 
    Id. at A28.
    The Mine Commission affirmed,
    concluding that that the ALJ “was correct in concluding that
    the Carbon Plant performs the ‘work of preparing the coal,’
    and thus is a ‘mine’ . . . subject to jurisdiction under the Mine
    Act.” 
    Id. at A38.
    E. Evidentiary Ruling
    The ALJ granted the Secretary’s motion seeking to
    exclude evidence gathered by a 2004 MSHA fact-finding
    committee that had reviewed operations at seven facilities
    that Shamokin claimed were similar to its carbon plant. The
    ALJ first found that the evidence of MSHA’s oversight over
    other facilities was irrelevant because MSHA jurisdiction
    should be determined on a “case-by-case basis.” 
    Id. at A2.
    It
    also found that, even if it were relevant, it should be excluded
    because “its probative value [was] . . . substantially
    outweighed by a danger of unfair prejudice, confusion of the
    issues, or . . . a waste of time or needless presentation of
    cumulative evidence.” 
    Id. (relying on
    29 C.F.R. § 2700.63(a),
    which provides, “relevant evidence, including hearsay
    evidence, that is not unduly repetitious or cumulative is
    admissible,” and Federal Rule of Evidence 403). The ALJ
    9
    reasoned that the balance in this case weighed in favor of
    exclusion given the case-by-case nature of the inquiry over
    whether MSHA jurisdiction is proper; the fact that it would
    be “cumbersome and impractical” to review “whether and
    why MSHA has exercised or should exercise jurisdiction over
    similar ‘bagging facilities’”; and that Shamokin would be not
    be prejudiced given the otherwise wide breadth of the
    evidentiary hearing. App. at A2-3.
    The ALJ revisited the evidentiary determination after
    the hearing itself, adding that there was no appellate case law
    on the question of whether “a comparative facility analysis
    approach” was proper. 
    Id. at A9.
    Accordingly, the ALJ found
    that the approach Shamokin requested would detract from
    analysis of the particular facility at issue, sending the tribunal
    on a “jurisdictional safari, searching out all similar facilities
    in the country and comparing alike and non-alike activities,
    structures, operations, and products with that of the subject
    Carbon Plant. [] The collateral inquiries would be endless.”
    
    Id. at A10.
    The Mine Commission’s appellate body affirmed
    under an abuse of discretion standard, adding that
    Administrative Procedure Act § 556(d) imposes an obligation
    on the agency to have a policy to exclude “irrelevant,
    immaterial, or unduly repetitious evidence.” 
    Id. at A39
    (citing
    5 U.S.C. § 556(d)). The Mine Commission agreed that the
    evidence was not relevant because “[i]t is unlikely that any
    two facilities would be identical and warrant the same
    conclusion on jurisdiction,” and jurisdiction is “governed by
    the statute, rather than by which of two conflicting
    interpretations by the Solicitor is correct.” App. at A39
    (internal quotation marks and citations omitted). Moreover,
    10
    given that the evidence was of “limited probative value,” its
    introduction would have “unduly delayed the trial”—
    Shamokin would have had to present “a significant number of
    additional witnesses” to “demonstrate the similarities between
    those facilities and its Carbon Plant.” 
    Id. at A40.
    Finally, the
    appellate body noted that MSHA has asserted jurisdiction
    over Shamokin’s plant for decades, and that there has been no
    change in Shamokin’s operations. 
    Id. II. DISCUSSION
    A. 30 U.S.C. § 802: “work of preparing the coal”
    Under our functional analysis, Shomakin is engaged in
    “the work of preparing the coal.” In RNS, the loading of coal
    for transport to another facility for further processing was
    considered “the work of preparing the coal,” because the
    “storage and loading of the coal is a critical step in the
    processing of minerals extracted from the earth in preparation
    for their receipt by an end-user, and the Mine Act was
    intended to reach all such 
    activities.” 115 F.3d at 185
    .
    Shamokin does more than the facility in RNS: Shamokin
    admits that it stores, dries, screens, and bags coal. Under RNS,
    it is subject to MSHA jurisdiction.
    Shamokin nonetheless argues that it is not engaged in
    the work of preparing coal under the Mine Act definition
    because it purchases coal that has already been processed.
    Shamokin supports its argument in four ways worth
    addressing: first, through statutory interpretation, second,
    through relying on a definition of “coal preparation” from the
    now defunct U.S. Bureau of Mines, third, by arguing that the
    statute would lack meaningful boundaries without its
    11
    proposed limitation, and finally, by relying on case law from
    various Courts of Appeals. Each argument will be addressed
    in turn.
    Shamokin first makes a statutory argument.             It
    contends that the last phrase in § 802(i), “and such other work
    of preparing such coal as is usually done by the operator of
    the coal mine,” modifies the earlier items in the list such that
    only functions that are usually done by the “operator of a coal
    mine” are regulated under the Mine Act. Petitioner’s Br. at 13
    (emphasis added). In turn, only processing of “raw,” “run-of-
    mill” or unprepared coal, not the processing of coal that is
    already in “usable or marketable condition,” would usually be
    done by an operator of a coal mine. 
    Id. The Secretary
    responds that the Mine Act contains no such limitation.
    We believe the Secretary is correct. The words “raw”
    or “unprepared” or “run-of-mill” never appear anywhere in
    the Mine Act definitions, a strong indication that Congress
    never restricted Mine Act coverage to those facilities that
    begin with coal in these states. Additionally, in RNS, we
    addressed the last phrase in § 802(i), and rejected the
    predicate of the argument that Shamokin raises here—
    whether the activities at the plant are usually done by the
    operator of a hypothetical coal mine is not relevant in the
    analysis. In RNS, we placed emphasis on the definite article in
    the phrase “as is usually done by the operator of the coal
    
    mine.” 115 F.3d at 185
    (emphasis added) (internal quotation
    marks omitted). We decided that if 802(i) had an indefinite
    article in place of the definite article, reading instead “the
    operator of a coal mine,” this clause could imply that “one
    might have to compare the activities at the alleged coal mine
    with those of a typical, paradigmatic, ‘usual’ coal mine.” RNS
    12
    Servs. 
    Inc., 115 F.3d at 185
    . However, the sentence as
    written differs. It “simply explains that the work of the coal
    mine is the work that is usually done in that particular place.
    The fact that [a] [s]ite is perhaps an unconventional coal mine
    does not defeat its status as a coal mine for the purposes of
    [§] 802.” 
    Id. Shamokin’s statutory
    argument is therefore
    without merit.
    Shamokin’s second argument borrows from the
    Dictionary of Mining, Mineral and Related Terms published
    by the U.S. Bureau of Mines, a now defunct federal agency
    that conducted scientific research on the extraction,
    processing, use, and conservation of mineral resources until
    its closure in 1995. The Bureau had defined “coal
    preparation” as “[t]he various physical and mechanical
    processes in which raw coal is dedusted, graded, and treated
    by dry methods (rarely) or water methods, using dense-media
    separation (sink-float), jigs, tables, and flotation. The
    objective is the removal of free dirt, sulfur, and other
    undesirable constituents.” 3 This definition is at least eighteen
    years old and is from an agency that was tasked not with
    safety but rather research. In any event, the words “raw coal”
    do not appear in the Mine Act, and Shamokin has failed to
    show why this definition should take precedence over the one
    in the Mine Act.
    Third, Shamokin asserts that unless the work of
    preparing coal ends “when the raw, run-of-mill extracted
    material has been processed into a usable condition,” the list
    3
    Available at
    http://webharvest.gov/peth04/20041015011634/imcg.wr.usgs.
    gov/dmmrt/ (last accessed June 30, 2014) (emphasis added).
    13
    of activities enumerated in § 802(i) would be unworkably
    broad. Petitioner’s Br. at 14. Such an interpretation, the
    argument runs, could include “anyone who handles coal, no
    matter how far down the stream of commerce,” subsuming
    non-mining activities such as operations “that use processed
    coal for heating, powering equipment, as a feedstock in
    producing other products, or which merely transport the
    processed coal.” 
    Id. at 14-15.
    But this Court’s functional
    approach has already managed to weed out such activities.
    For example, without Shamokin’s proposed limitation, we
    determined that delivery of raw coal to a processing facility,
    but not delivery of processed coal to the consumer, counts as
    the work of preparing the coal. See RNS Servs., 
    Inc., 115 F.3d at 184
    . In RNS, the loading of coal for transport to another
    facility for further processing was considered “the work of
    preparing the coal” because the “storage and loading of the
    coal is a critical step in the processing of minerals extracted
    from the earth in preparation for their receipt by an end-user,
    and the Mine Act was intended to reach all such activities.”
    
    Id. at 185.
    Thus, through the rubric of the functional test,
    activities that are too far attenuated from the actual processing
    of coal, and which are not “critical” or “integral,” see 
    id. at 185-86,
    in preparation of receipt by the end user, will not be
    subsumed under the Mine Act definition and in fact have not
    been.
    Contrary to Shamokin’s assertion, our opinion in
    Dowd v. Director, Office of Workers’ Compensation
    Programs, 
    846 F.2d 193
    , 194-195 (3d Cir. 1988) does not
    counsel in favor of another result. 4 In Dowd, we determined
    4
    Dowd is of limited import here because it was decided under
    Title IV of the Mine Act, or the Black Lung Benefits Act of
    14
    that a worker was involved in the preparation of coal at a
    “custom coal preparation facility” because his employer dried
    and crushed “unprepared anthracite [coal].” 
    Id. at 195.
    Shamokin asks us to extrapolate from this that the work of
    further preparing prepared coal would thus not be considered
    coal preparation. In so doing, it requests that we convert a
    sufficient condition into a necessary one, but nothing about
    the opinion implies that the facilities have to begin with
    unprepared anthracite to be “custom coal preparation
    facilities.”
    Finally, Shamokin attempts to demonstrate that courts
    routinely cut off Mine Act jurisdiction at the point where raw
    coal becomes usable. Having reviewed the cases cited, we
    agree with the Secretary that none of these cases stands for

    It is also worth noting that Shamokin’s most serious
    mine safety citations involved violations of MSHA’s
    respirable dust standards. Given that the activities at
    Shamokin’s plant trigger the types of safety concerns that the
    Mine Act was intended to remedy, it would defy Congress’s
    intent to allow Shamokin to escape Mine Act jurisdiction
    based on a formality. See RNS Servs., 
    Inc., 115 F.3d at 187
    (noting that the Mine Commission had “legitimate concerns
    about worker safety and health at the Site,” which included
    “[t]rue potential hazards” such as “circulation of dust”).
    Thus, we decline Shamokin’s invitation to impose
    additional limitations not in the statute and find that MSHA’s
    assertion of jurisdiction over the plant was proper.

    impose a bright line rule that preparation ends “at the point
    when the coal is placed into the processing tipple because we
    are not convinced that each step essential to the preparation of
    the coal for entry into the stream of commerce is completed at
    that point. Thus, [the employer’s] participation in the removal
    of the coal from the tipple was a step, if only the very last
    step, in the preparation of the coal.” Hanna v. Dir., Office of

    B. Evidentiary Appeal
    Shamokin also challenges the ALJ’s decision to
    exclude evidence of MSHA’s non-assertion of jurisdiction
    over plants that Shamokin claims are its competitors.
    Shamokin contends that the evidence would have showed an
    inconsistent position regarding MSHA’s exercise of
    jurisdiction over carbon products plants such as Shamokin’s,
    which could call into question the propriety of the Secretary’s
    assertion of jurisdiction here.
    Shamokin submits that a number of memoranda are
    relevant to the question of whether MSHA has consistently
    interpreted the statute to allow for jurisdiction over the further
    processing of non-raw coal. In its brief, Shamokin discusses
    only the operations of the Keystone Filler & Manufacturing
    plant, highlighting a June 22, 2004 memorandum as
    representative, so that is the plant and memorandum we will
    address. According to this memorandum, written by Counsel
    for Standards, Mine Safety and Health, to a District Manager
    of MSHA, Keystone’s facility was not engaged in the “work
    of preparing the coal” because,
    once the coal arrives at this facility, it is already
    fully prepared and ready to be used by Keystone
    as a chemical compound ingredient in the
    manufacture of saleable products for the rubber,
    plastics, and steel products industries. . . . Other
    ingredients are added to it such as coke,
    petroleum laced coke and graphite. Any
    oversized pieces are crushed at Keystone, but
    this crushing is incidental to the manufacturing
    process. As a consumer of fully processed coal
    17
    sold in the open market, Keystone’s work
    constitutes manufacturing rather than mining,
    and as such, not subject to MSHA jurisdiction. .
    . . [P]reparation ends when the coal is ready for
    use.
    App. at A184.
    We agree that the consistency of an agency’s
    application of a statute might be relevant. See, e.g., Westar
    Energy, Inc. v. Fed. Energy Regulatory Comm’n, 
    473 F.3d 1239
    , 1243 (D.C. Cir. 2007) (“The Order under review is
    arbitrary and capricious in that it provides no basis in fact or
    in logic for the Commission’s refusal to treat Westar as it had
    treated KCPL.”). However, this memorandum is not relevant.
    Keystone was engaged in manufacturing, not coal processing.
    Shamokin argued unsuccessfully to the Mine Commission
    that it, like Keystone, was mainly engaged in the manufacture
    of carbon-based products for the steel, rubber, and plastics
    industries. The Mine Commission determined this assertion
    was factually without merit, as inspectors found no mixing of
    coal with non-coal materials at the plant, and the records
    supplied by Shamokin confirmed that it sold only a few tons
    of products containing no coal or coal mixtures. As such,
    Shamokin’s comparison to Keystone is not apt, as Shamokin
    was mainly engaged in coal processing, not manufacturing of
    other products using coal.
    Furthermore, as the Mine Commission pointed out,
    better evidence on the consistency of MSHA’s jurisdictional
    decisions is the fact that the Secretary through MSHA has
    asserted jurisdiction over Shamokin from 1977 to 2009
    without a change in its operations when the new owners
    18
    assumed the helm. Indeed, this demonstrates that the
    Secretary has consistently interpreted the statute. We also
    agree with the ALJ’s assessment that the introduction of this
    evidence could have opened up a stream of requests for
    comparisons to facilities all around the country, causing an
    unnecessary delay in the proceedings to address collateral
    matters.
    Given the limited probative value of the evidence, and
    the potential it had to unnecessarily delay the hearing, we
    affirm the Mine Commission’s decision to exclude the
    evidence of MSHA’s non-assertion of jurisdiction over other
    facilities. We find that the agency’s decision was not an abuse
    of discretion. Cf. Bhaya v. Westinghouse Elec. Corp., 
    922 F.2d 184
    , 187 (3d Cir. 1990); see also United States v. Long,
    
    574 F.2d 761
    , 767 (3d Cir. 1978) (“If judicial self-restraint is
    ever desirable, it is when a Rule 403 analysis of a trial court is
    reviewed by an appellate tribunal.”).
    III. CONCLUSION
    For the foregoing reasons, we will deny the Petition
    for Review of the Mine Commission’s final order. The
    Secretary’s exercise of jurisdiction over Shamokin through
    MSHA was proper. Furthermore, the ALJ did not commit an
    abuse of discretion by failing to allow into evidence internal
    memoranda between MSHA employees regarding the
    non-assertion of jurisdiction over other facilities.
