    Opinion for the Court filed by Circuit Judge PILLARD.
    2
    PILLARD, Circuit Judge: Coal powers almost 40% of the
    electricity used in the United States. Despite enormous safety
    advances in recent decades, underground coal mining remains
    one of the handful of the nation’s most dangerous jobs. Cave-
    ins, and dusts or gases that pose respiratory or explosion risks,
    are leading causes of harm to coal miners.1 Congress enacted
    the Federal Mine Safety and Health Amendments Act of 1977
    (the Mine Act) to protect America’s miners. The Mine Act
    subjects mine operators to substantial safety regulation, under
    rules generally applicable to all mines, as well as mine-
    specific safety plans suited to the particular geologic
    conditions and the operator’s chosen mining system.
    Operators must propose mine-specific plans for the approval
    of the Secretary of Labor, who acts for those purposes
    through a district manager in the Mine Safety and Health
    Administration (MSHA). The Mine Act established the
    Federal Mine Safety and Health Review Commission, an
    independent agency, to review operators’ challenges to
    citations and orders the Secretary imposes under the Act.
    Petitioner Prairie State Generating Company, LLC (Prairie
    State) challenges the Commission’s decision to sustain the
    Secretary’s citations against it for operating without approved,
    mine-specific plans for roof support and ventilation at Prairie

    State’s underground coal mine at Lively Grove in southern
    Illinois. After extensive consultation over the terms of mine-
    specific safety plans that would be suitable at Lively Grove,
    the MSHA district manager had declined to accept the final
    terms that Prairie State proposed. In order to create an
    opportunity to challenge the district manager’s plan-suitability
    decisions, Prairie State momentarily operated the mine
    without approved roof-support and ventilation plans and so
    incurred two citations, which it challenges here.
    The principal question before us is which standard the
    Commission should use when it reviews the Secretary’s
    citation of an operator for failure to follow an approved,
    mine-specific plan. The Secretary defends arbitrary-and-
    capricious review as appropriately deferential to his
    judgments because the Department of Labor is the agency
    charged under the Mine Act with expert policymaking
    discretion to evaluate and approve mine-specific safety plans.
    Prairie State, by contrast, argues for de novo review on the
    ground that the Secretary will not have carried his
    acknowledged burden to prove the basis for a citation unless
    he establishes, without the benefit of deference, the
    unsuitability of an operator’s proposed plan. Prairie State
    claims two further legal errors: First, that the Commission
    erred as a matter of law by not considering evidence that,
    Prairie State contends, is relevant notwithstanding that it was
    not submitted to the district manager when he decided plan
    suitability; and second, that the district manager erroneously
    relied on an MSHA Procedure Instruction Letter as a binding,
    across-the-board norm in derogation of his duty to make a
    case-specific judgment. Finally, Prairie State points out
    various ways in which, even if the suitability determinations
    were reviewed with deference, it believes the determinations
    were contrary to law and unsupported by substantial evidence.
    4
    We hold that that the Secretary’s judgments regarding the
    suitability of mine-specific safety plans are entitled to
    deference under the Mine Act, and reject the further claims of
    error.
    I.
    The Mine Act charges two separate agencies with
    complementary policymaking and adjudicative functions.2
    The Secretary, acting through MSHA, sets regulatory
    standards of mine safety, conducts regular mine inspections,
    and issues citations and orders in response to violations. 29
    U.S.C. § 557a; 
    30 U.S.C. §§ 813
    , 814; Thunder Basin Coal
    Co. v. Reich, 
    510 U.S. 200
    , 202-04 & n.5 (1994). The
    Commission, an adjudicatory body established as independent
    of the Secretary, reviews challenges to MSHA’s actions. 
    30 U.S.C. §§ 815
    (d), 823. The Mine Act’s split-function
    approach contrasts with the more typical administrative
    structure, in which rulemaking and adjudication are
    performed within a single agency. See generally Martin v.
    Occupational Safety & Health Review Comm’n, 
    499 U.S. 144
    ,
    151 (1991) (describing the analogous, split-function scheme
    under the Occupational Safety and Health Act (OSH Act)); 2
    Charles H. Koch, Jr. & Richard Murphy, Administrative Law
    & Practice § 5:29 (3d ed.). The extra institutional separation
    the Mine Act provides reflects Congress’s concern that the

    Pub. L. No. 95-164, 
    91 Stat. 1290
     (1977), codified as amended at
    
    30 U.S.C. § 801
     et seq. The Mine Act amended the Federal Coal
    Mine Health and Safety Act of 1969 (the Coal Act), Pub. L. No. 91-
    173, 
    83 Stat. 742
     (1969), by extending the coverage of the existing
    regulatory regime to non-coal mines and strengthening its
    protections of miners. See United Mine Workers of Am., Int’l
    Union v. Dole, 
    870 F.2d 662
    , 666 n.5 (D.C. Cir. 1989); S. Rep. No.
    95-181, at 9 (1977), reprinted in 1977 U.S.C.C.A.N. 3401, 3409.

    adjudicatory function be institutionally independent of
    potential influence by the agency responsible for
    policymaking and enforcement decisions. See S. Rep. No.
    95-181, at 47 (1977), reprinted in 1977 U.S.C.C.A.N. 3401,
    3447 (“[A]n independent Commission is essential to provide
    administrative adjudication which preserves due process and
    instills much more confidence in the program.”).
    The Mine Act requires the Secretary, acting through an
    MSHA district manager assigned to one of the nation’s twelve
    mining districts, to negotiate mine-specific roof-support and
    ventilation plans with representatives of the companies that
    operate the mines. Congress decided that “individually
    tailored plans, with a nucleus of commonly accepted
    practices, are the best method of regulating such complex and
    potentially multifaceted problems as ventilation, roof control
    and the like.” Dole, 
    870 F.2d at
    669 n.10 (quoting S. Rep.
    No. 95-181 at 25, 1977 U.S.C.C.A.N. at 3425). As outlined
    below, the operators propose plans for the Secretary’s
    consideration that they believe are “suitable” to ensure
    adequate roof support and ventilation based on each mine’s
    unique geology and proposed mining system. 
    30 U.S.C. §§ 862
    (a), 863(o); see Mach Mining, LLC v. Sec’y of Labor,
    
    728 F.3d 643
    , 649 (7th Cir. 2013). No mine may operate
    without an approved plan, and once the Secretary has
    approved a plan, its terms are enforceable as if they were duly
    promulgated regulations. 
    30 C.F.R. §§ 75.220
    (c), 75.370(d);
    see Dole, 
    870 F.2d at
    667 & n.7; Zeigler Coal Co. v. Kleppe,
    
    536 F.2d 398
    , 409 (D.C. Cir. 1976) (interpreting the
    predecessor Coal Act).
    The first step in the process of plan approval is for a mine
    operator to develop roof-support and ventilation plans it
    thinks are suitable, and to submit the plans to the district
    manager for his or her consideration. 
    30 C.F.R. §§ 75.220
    (a),
    6
    75.370(a); see 
    30 U.S.C. §§ 862
    (a), 863(o); Dole, 
    870 F.2d at
    668-69 & n.10. The operator must also provide proposed
    plans to the mine workers’ representative prior to submitting
    them to the district manager, so that the representative may
    make comments for the district manager’s consideration. 
    30 C.F.R. § 75.370
    (a)(3), (b). The district manager evaluates the
    operator’s proposed plans (and miners’ comments) in
    accordance with the Secretary’s policy judgment, and in light
    of information about the prospective site and the agency’s
    accumulated knowledge and experience. See 
    30 U.S.C. §§ 862
    (a), 863(o); 
    30 C.F.R. §§ 75.220
    (a), 75.370(a); S. Rep.
    No. 95-181 at 25, 1977 U.S.C.C.A.N. at 3425. If the district
    manager deems an operator’s proposed plan insufficient to
    ensure miners’ health and safety, he or she denies approval,
    explaining relevant concerns to the operator and giving the
    operator a chance to address the identified deficiencies. 
    30 C.F.R. §§ 75.220
    (b), 75.370(c). The operator and the district
    manager then engage in a good-faith negotiation in an effort
    to formulate a plan with which they both are satisfied. 
    Id.
    §§ 75.220(a), 75.370(a), (c)(2); see Sec’y of Labor v. Carbon
    Cnty. Coal Co., 
    7 FMSHRC 1367
    , 1371 (1985). The operator
    “ha[s] a role to play in developing plan contents, [but] [the
    Secretary] always retain[s] final responsibility for deciding
    what ha[s] to be included in the plan.” Dole, 
    870 F.2d at
    669
    n.10; see 
    30 U.S.C. §§ 862
    (a), 863(o) (operators shall only
    adopt plans “approved by” the Secretary). In other words,
    “‘while the operator proposes a plan and is entitled . . . to
    further consultation with the Secretary over revisions, the
    Secretary must independently exercise his judgment with
    respect to the content of such plans in connection with his
    final approval of the plan.’” Dole, 
    870 F.2d at
    669 n.10
    (quoting S. Rep. No. 95-181 at 25, 1977 U.S.C.C.A.N. at
    3425). If a mine operates without an approved, mine-specific
    plan, the Secretary may issue citations, orders to withdraw
    7
    from the mine, civil fines, and criminal penalties. 
    30 U.S.C. §§ 814
    (a), (d), 815, 820.
    The independent Commission is the administrative
    adjudicator under the Mine Act. 
    30 U.S.C. §§ 815
    , 823. A
    mine operator may appeal a citation issued by the Secretary to
    an administrative law judge, who conducts a hearing on
    behalf of the Commission in accordance with the
    Administrative Procedure Act. 
    Id.
     §§ 815(d), 823(d)(1). At
    the hearing, the Secretary must support its citation by a
    preponderance of evidence in the record. See 
    5 U.S.C. §§ 554
    (c)(2), 556(d); Steadman v. SEC, 
    450 U.S. 91
    , 102
    (1981) (interpreting “substantial evidence” under APA
    Section 556 to mean a preponderance of evidence). Based on
    the hearing and any related briefing, the ALJ makes findings
    of fact and either affirms, modifies, or vacates the Secretary’s
    decisions. 
    30 U.S.C. §§ 815
    (d), 823(d)(1). A mine operator
    may petition the Commission for discretionary review of an
    ALJ’s order. 
    Id.
     § 823(a), (d)(2)(A). The Commission sits in
    Washington, D.C., and is comprised of five members, each
    appointed by the President with the advice and consent of the
    Senate, to a tenure-protected, six-year term. Id. § 823(a), (b).
    If the Commission denies review, the ALJ’s decision becomes
    final. Id. § 823(d)(1). A person affected by a Commission
    decision has a right to review in this court or the court of
    appeals for the circuit in which the alleged violation
    occurred.3 Id. § 816(a)(1).
    3
    By contrast, anyone affected by the promulgation of a generally
    applicable rule may directly petition the Courts of Appeals for
    review; in those cases, the Mine Act does not call for administrative
    review by the Commission (or its ALJs). 
    30 U.S.C. § 811
    (d). The
    Secretary’s exercise of his general rulemaking authority is subject
    to deferential judicial review. Dole, 
    870 F.2d at 666-67
    .
    8
    An operator may only commence mining under a plan the
    Secretary has approved, through a district manager, as
    “suitable.” 
    30 U.S.C. §§ 862
    (a), 863(o); 
    30 C.F.R. §§ 75.220
    ,
    75.370. Sometimes, as in this case, an operator and district
    manager fail to reach agreement on suitable plan terms. The
    statute does not explicitly provide for administrative and
    judicial review of a district manager’s refusal to accept the
    operator’s proposed plan terms as suitable, but the Secretary
    and operators have developed a “technical citation” practice
    in order to enable review. See Mach Mining, 728 F.3d at 651-
    54. An operator that wishes to challenge a district manager’s
    suitability decision momentarily commences operations under
    its preferred terms, without the requisite approval by the
    Secretary, prompting the Secretary to issue a technical
    citation that carries a nominal monetary penalty. Id. at 655-
    56. The operator then appeals the technical citation to the
    Commission and, as appropriate, a federal court of appeals.
    The technical citation process is described in the Secretary’s
    policy manual. MSHA, Program Policy Manual Vol. V (Dec.
    2013, Release V-48), at 5.4
    II.
    In 2008, Prairie State proposed to construct an
    underground coal mine at the Lively Grove site in southern
    Illinois. At Lively Grove, Prairie State prepared to use large,
    remote-controlled, continuous mining machines that take cuts
    into the coal seam, convey the cut coal back to be carted out
    4
    A 2006 amendment to the Mine Act codified the technical citation
    route to obtaining review in the face of disagreement over mine-
    specific accident response plans, 
    30 U.S.C. § 876
    (b)(2)(G), but not
    with respect to disagreements regarding the suitability of roof-
    support and ventilation plans, see Mach Mining, 728 F.3d at 655.
    The validity of the technical citation process is not at issue here.
    9
    of the mine, and—once they have tunneled into the seam to a
    target depth—withdraw from the coal face so that miners can
    use roofbolts or other supports to secure the roof above where
    the coal was removed. Prairie State proposed to make 40-foot
    deep cuts into the seam, and to create openings 20 feet across
    and, at tunnel intersections, 68 feet in diagonal span. For
    ventilation, Prairie State proposed to use a “fishtail”
    ventilation system, which circulates fresh air into the mine
    and splits the air stream, ensuring fresher air to more mine
    areas than a single stream that travels further and, it claims,
    can carry contaminants within the mine. Prairie State’s
    position was that, with the fishtail system, ventilating 9,000 to
    12,000 cubic feet per minute of air would suffice, depending
    on the number of open crosscuts.
    Area geology around Lively Grove was known to the
    Secretary to present risks of roof falls and hazardous methane
    emissions. The district manager and his staff reviewed Prairie
    State’s submissions in this case, determined that Prairie
    State’s proposed plans were inadequate, and communicated
    their concerns to Prairie State along with suggested plan
    revisions. Over the ensuing year, Prairie State and the district
    manager traded written correspondence and engaged in more
    than thirty discussions regarding plan terms. They failed to
    reach agreement, however, on the issues of maximum
    permissible cut depth, tunnel entry width, diagonal span of
    tunnel intersections, and the adequacy of the ventilation
    system Prairie State proposed in the mine. The district
    manager declined to approve, at least at the outset in the
    absence of mining history at the site, cuts deeper than 20 feet,
    tunnel entries wider than 18 feet, and intersection diagonals
    longer than 64 feet. With respect to air quantities, the district
    manager called for ventilation of 20,000 to 25,000 cubic feet
    per minute—more than twice Prairie State’s proposed
    volume. In light of the district manager’s disapproval of
    10
    Prairie State’s proposed terms, Prairie State triggered
    technical citations regarding roof-support and ventilation
    plans, which it challenged before the Commission.
    The Commission assigned the citation challenges to an
    ALJ to conduct a hearing. The ALJ heard testimony on the
    merits of Prairie State’s claims. The district manager, along
    with the roof-support and ventilation specialists working
    under his supervision, testified on the Secretary’s behalf.
    Prairie State’s representatives and expert witnesses also
    testified. With the benefit of post-hearing briefing, the ALJ
    affirmed both citations in a written opinion. The ALJ made
    factual findings describing the plan proposal, evaluation,
    negotiation, and plan-suitability determinations at Lively
    Grove.
    The ALJ sustained the Secretary’s determination that
    Prairie State’s proposed plans were unsuitable. Over Prairie
    State’s objection, the ALJ held as a matter of law that plan
    suitability is appropriately assessed “in terms of the discretion
    of the district manager” under a “standard of review [that]
    incorporates an element of reasonableness.” 
    32 FMSHRC 602
    , 608 (May 2010). The ALJ then rejected Prairie State’s
    assertion that the district manager’s discretion was
    impermissibly constrained by a Procedure Instruction Letter
    that the Secretary had issued outlining procedures for
    evaluating operators’ requests for extended cuts. The ALJ
    also excluded evidence about plans at other mines that Prairie
    State sought to introduce at the hearing on the ground that
    Prairie State had not submitted that evidence to the Secretary
    during plan negotiations.
    The Commission granted Prairie State’s petition for
    discretionary review and affirmed the ALJ on most issues.
    The Commission agreed with the ALJ’s determination that the
    11
    citations were subject to arbitrary-and-capricious review by
    the Commission and its ALJs because that standard
    “appropriately respects the Secretary’s judgment while
    allowing review for abuse of discretion, errors of law, and
    review of the record under the substantial evidence test.” 
    35 FMSHRC 1985
    , 1990, 
    2013 WL 3947974
     (July 2013)
    (internal quotation marks omitted). Deference is warranted in
    this context, the Commission reasoned, because ALJs and
    Commissioners “are not always best-equipped to decide
    technical issues regarding ventilation and roof control,” and
    “are instead charged with deciding whether the district
    manager has made a fair and informed suitability
    determination.” 
    Id.
     at 1989 n.6. One Commissioner
    dissented, stating that Commission precedent “ha[d] long held
    that the Secretary bears the burden of establishing that the
    operator’s plan . . . was unsuitable,” and that the ALJ had
    “short-circuited the [review] process by avoiding the
    threshold question of unsuitability,” “effectively replac[ing]
    the burden of proof with a deferential ‘review’ of the
    rationality of the District Manager’s negotiating position.” 
    Id. at 1998-99
     (Young, Comm’r, dissenting).
    The Commission affirmed the ALJ’s rulings regarding
    evidentiary exclusions, reliance on the Procedure Instruction
    Letter, and the merits of Prairie State’s challenges regarding
    cut depth, entry width, and diagonals. The Commission
    ordered a limited remand for the ALJ to explain her
    conclusion regarding ventilation. On remand, the ALJ
    provided further reasoning regarding the ventilation plan
    issue, and assessed a $200 penalty for Prairie State’s two
    technical citations. Prairie State again appealed to the
    Commission, which denied further review. Prairie State then
    timely petitioned this court.

    We review the legal determinations of the Commission
    and its ALJs de novo and factual findings for substantial
    evidentiary support.

    A.
    The threshold question in this case concerns the standard
    under which the Commission and its ALJs review the
    Secretary’s plan-suitability determinations in the context of a
    challenge to a technical citation. We may assume, without
    deciding, that Chevron governs our consideration of that
    question, as Prairie State failed to contest the Secretary’s
    assertion that it does.5 Because the Mine Act itself does not
    provide a definitive answer, see 
    30 U.S.C. § 815
    (d), we

    But see Steadman, 
    450 U.S. at 95
     (“Where Congress has not
    prescribed the degree of proof which must be adduced by the
    proponent of a rule or order to carry its burden of persuasion in an
    administrative proceeding, this Court has felt at liberty to prescribe
    the standard, for it is the kind of question which has traditionally
    been left to the judiciary to resolve.”) (internal quotation marks &
    alteration marks omitted); Mach Mining, 728 F.3d at 647

    to apply a deferential standard of review to the Secretary’s approval

    consider it under Chevron’s second step, deferring to the
    Commission’s reasonable interpretation of the Act, see
    Chevron, U.S.A., Inc. v. Natural Res. Def. Council, Inc., 
    467 U.S. 837
    , 842-43 (1984).
    The Commission has chosen to review the Secretary’s
    plan determinations deferentially, and the Mine Act allows
    that choice. It is well established that the Commission and the
    courts owe deference to the Secretary’s interpretation of the
    Mine Act and generally-applicable regulations promulgated
    thereunder. See, e.g., Akzo Nobel Salt, Inc. v. Fed. Mine
    Safety & Health Review Comm’n, 
    212 F.3d 1301
    , 1303 (D.C.
    Cir. 2000); Sec’y of Labor v. Cannelton Indus., Inc., 
    867 F.2d 1432
    , 1435 (D.C. Cir. 1989); see generally 2 Koch &
    Murphy, Administrative Law & Practice § 5:29. The plans at
    issue here are sufficiently analogous to render reasonable the
    Commission’s approach.
    The Commission treats mine-specific safety plans as, in
    effect, contextually specific, mini regulations, similarly
    entitled to deference. The Senate Report supports the
    analogy. In discussing the Act’s requirement of mine-specific
    plans to govern certain safety issues, the Report stated that
    “[s]uch individually tailored plans, with a nucleus of
    commonly accepted practices, are the best method of
    regulating such complex and potentially multifaceted
    problems as ventilation, roof control and the like.” S. Rep.
    No. 95-181, at 25, 1977 U.S.C.C.A.N. at 3425. Once the
    Secretary approves them, the provisions of a mine-specific
    plan are as binding as a generally-applicable, duly-
    promulgated rule. Dole, 
    870 F.2d at
    667 & n.7; Zeigler, 536
    F.2d at 409. The Commission reasonably deemed the
    Secretary’s determinations regarding roof support and
    ventilation as worthy of deference, given that they entail case-
    by-case judgments in the field based on unique geological
    14
    conditions and mining systems—judgments that the expert,
    policymaking agency is charged with and better equipped to
    make. See id.; 
    30 U.S.C. §§ 862
    (a), 863(o).
    The statutory requirements of negotiation between the
    Secretary and an operator in the development of suitable,
    mine-specific plans, and the Mine Act’s provision for miners’
    input during the plan-approval process, can be thought to play
    a role in the development of mine-specific plans akin to that
    of notice and comment in formal administrative rulemaking.
    Mine operators receive written notice of the reasoning and
    bases for the Secretary’s initial plan-suitability determinations
    and have multiple opportunities to respond with arguments
    and supplemental data. Carbon County, 7 FMSHRC at 1370-
    71; 
    30 C.F.R. §§ 75.220
    , 75.370. Plan negotiations thus may
    reasonably be characterized as serving the same interests as
    notice and comment, albeit less formally: notice to affected
    parties, opportunities for such parties to develop the record by
    submitting factual and legal support, and improvement of the
    agency’s decisionmaking. See, e.g., Small Refiner Lead
    Phase-Down Task Force v. EPA, 
    705 F.2d 506
    , 547 (D.C.
    Cir. 1983). Prairie State objects that the Secretary has
    effectively imposed rules without the protection of notice and
    comment, but the Commission reasonably treated the plan-
    negotiation process as giving operators adequate opportunity
    to frame the issues, have their views heard, and persuade the
    agency to make salutary changes.
    The Supreme Court’s treatment of the split-function
    structure created by the OSH Act, which closely parallels the
    Mine Act, also supports that analysis. See Martin, 
    499 U.S. at 152-55
    . The OSH Act’s “administrative and judicial review
    procedures . . . are nearly identical to those in the Mine Act,”
    which is “hardly surprising since . . . the Mine Act’s review
    process was written to conform to the review process of the
    15
    OSH Act.” Sturm, Ruger & Co. v. Chao, 
    300 F.3d 867
    , 872
    (D.C. Cir. 2002) (internal quotation marks omitted). In
    Martin, the Supreme Court distinguished the split-function
    occupational health and safety regime from the typical,
    unitary agency that uses adjudication as a policymaking tool,
    emphasizing that the independent OSH Review Commission
    lacks delegated power to make law and policy. 
    499 U.S. at 154
    . The Court stated that “Congress intended to delegate to
    the Commission the type of nonpolicymaking adjudicatory
    powers typically exercised by a court in the agency-review
    context,” and that, “[u]nder this conception of adjudication,
    the Commission is authorized to review the Secretary’s
    interpretations only for consistency with the regulatory
    language and for reasonableness.” 
    Id. at 154-55
    .
    Just as deference to the Secretary is warranted in the
    split-function administrative regime governing occupational
    health and safety, the institutional division and allocation of
    distinct functions under the Mine Act is fully consistent with
    limited, reasonableness review by the Commission of the
    Secretary’s plan-suitability determinations.       This court,
    following Martin, has recognized that the considered position
    of the Secretary in issuing a citation for violation of a
    generally-applicable mine safety regulation and defending it
    before the Commission is an exercise of delegated lawmaking
    power, and so entitled to deference. “The Secretary’s
    interpretation before the Commission is ‘agency action, not a
    post hoc rationalization of it.’ And, ‘when embodied in a
    citation, the Secretary’s interpretation assumes a form
    expressly provided for by Congress,’ and is therefore ‘as
    much an exercise of delegated lawmaking powers as is the
    Secretary’s promulgation of’ a regulation.” Akzo Nobel Salt,
    
    212 F.3d at 1304
     (quoting Martin, 
    499 U.S. at 157
    ).
    16
    The Seventh Circuit, the only other federal court of
    appeals to have decided this issue, held that the process the
    Mine Act put in place for developing mine-specific plans is
    incompatible with de novo review of such plans by the
    Commission:
    [T]he process of approving a ventilation plan
    proposed by the mine operator . . . involves the
    formulation of a standard, not the enforcement of a
    standard. It requires the gathering of information by
    the mine operator and its presentation to the district
    manager, the manager’s examining and assessing that
    material and considering the views of the operator on
    the appropriateness of the plan. At bottom, it entails
    the exercise of the Secretary’s independent judgment
    as to the appropriateness of the plan to ensure the
    health and safety of the miners. There is, in other
    words, a congressional mandate that the Secretary
    exercise independent judgment that the plan
    safeguards those whom it is designed to protect. . . .
    [T]he Secretary’s role of approving the plan is not
    really an enforcement role susceptible to de novo
    review, but rather a role imbued with a legislative or
    policy-making dimension to ensure that the plan is
    reflective of the public interest in mine safety.
    Mach Mining, 728 F.3d at 657. In short, the process of
    developing mine-specific plans requires the Secretary,
    through the district manager, to engage in detail with mine
    operators and bring to bear expertise and experience.
    Whether the Act thus requires the Commission’s deferential
    review, as Mach Mining held, or at least permits it, as we
    conclude, deferential review appropriately respects the
    Secretary’s policymaking prerogative and ensures that his
    determinations are reasonable and adequately supported by
    17
    the evidence. See Motor Vehicle Mfrs. Ass’n of U.S., Inc. v.
    Ruckelshaus, 
    719 F.2d 1159
    , 1164 (D.C. Cir. 1983).
    We reject Prairie State’s argument that the Mine Act’s
    incorporation of APA procedures necessarily puts the onus on
    the Secretary to prove to the Commission de novo the
    unsuitability of Prairie State’s preferred, mine-specific safety
    plans. Prairie State conflates the burden of proof with the
    standard of review. The statute requires the Secretary to
    prove, by a preponderance of evidence, the bases of citations
    it issues. 
    30 U.S.C. § 815
    (d); 
    5 U.S.C. §§ 554
    (c)(2), 556(d);
    see Steadman, 
    450 U.S. at 102
    . In this case, the “order” of
    which the Secretary is a “proponent,” 
    5 U.S.C. § 556
    (d), is the
    technical citation, and the basis of that citation is that the
    operator mined without an approved, suitable plan, see 
    30 U.S.C. § 814
    (a); 
    30 C.F.R. §§ 75.220
    (c), 75.370(d). That fact
    is not disputed here; the parties stipulated as much in order to
    trigger review.
    It does not follow from the Secretary’s burden under the
    APA to establish the grounds of a citation that the
    Commission must review de novo the Secretary’s underlying
    suitability determination. Consistent with the statute, the
    Commission has held that the Secretary’s burden is to
    persuade the Commission that the district manager did not
    abuse his discretion or act arbitrarily and capriciously in
    making his suitability determination, for instance by failing to
    examine relevant facts and draw reasonable conclusions. See,
    e.g., Sec’y of Labor v. Mach Mining, LLC, 
    34 FMSHRC 1784
    , 1790 & n.13 (Aug. 2012). As discussed below, the
    Commission correctly held the Secretary to that standard in
    this case. 35 FMSHRC at 1989-90; see infra Section III-B.
    We accept the Commission’s approach as a permissible
    reading of the Mine Act.
    18
    Prairie State relies on our decision in Zeigler for the
    proposition that, in reviewing a technical citation for
    operating without an approved safety plan, the Commission
    must presume the suitability of Prairie State’s preferred plan,
    and so require the Secretary to establish its unsuitability.
    Zeigler held that mine-specific plan requirements are
    enforceable on the same terms as generally-applicable
    regulatory standards. 536 F.2d at 409. Prairie State draws
    from Zeigler’s observation that a ventilation plan “is not
    formulated by the Secretary, but is ‘adopted by the operator,’”
    id. at 406, a presumptive legal primacy for the operator’s
    plan: It is, in Prairie State’s view, “[i]nherent in the Zeigler
    holding is that it is the operator’s proposal that is being
    evaluated, not the Secretary’s,” and thus the district manager
    may impose no different requirements until the operator’s
    plan has been proved to be unsuitable, Petitioner Br. 22. But
    that language in Zeigler aimed primarily at quelling operators’
    concerns that regulation through mine-specific plans might
    lead to “mine inspectors run riot,” using such plans as a
    means to evade the process for promulgating general rules on
    issues properly subject to general rulemaking by instead
    “simply insisting that newly formulated standards be included
    in one or another of the plans each operator must adopt.” 536
    F.2d at 406. No such end-run around the Mine Act’s general
    rulemaking is claimed here. Moreover, Zeigler recognizes, as
    do we, both the regulatory character of mine-specific plans,
    and the Secretary’s paramount control over and responsibility
    for mine-specific plans, which “must also be approved by the
    Secretary.” Id.; see also Dole, 
    870 F.2d at
    669 n.10 (although
    the operator “ha[s] a role to play in developing plan contents,
    [the Secretary] always retain[s] final responsibility for
    deciding what ha[s] to be included in the plan”).
    The nub of the parties’ dispute is whether the
    Commission reasonably concluded that it owes deference to
    19
    the Secretary’s action in this kind of case, involving a
    challenge to a technical citation on the ground that the district
    manager unlawfully eschewed Prairie State’s preferred terms.
    The question is whether judgments about suitable roof support
    and ventilation in a particular underground mine—made by
    the specialized, on-the-ground official of the agency that
    Congress vested with policymaking authority over mine
    safety decisions—are entitled to deference, or whether a
    national administrative adjudicator independent of that agency
    should exercise its judgment on those issues afresh, without
    giving any special weight to the policymaking agency’s
    determinations. Given that suitability is a discretionary,
    contextual exercise of expert judgment regarding the
    safeguards needed to keep miners safe, established principles
    of administrative law support the Commission’s deference to
    the Secretary here. See, e.g., Martin, 
    499 U.S. at 154-56
    .
    We therefore hold that the standard of review applied by
    the Commission was at least a permissible one.
    B.
    Prairie State further contends that, even under deferential
    review, the Commission reversibly erred in sustaining the
    district manager’s decisions regarding cut depth, entry widths,
    diagonals, and ventilation. We disagree.
    1.
    Prairie State asserts that the Commission’s ALJ
    incorrectly refused to consider evidence Prairie State
    proffered about plans approved for other mines—information
    that it concededly had not submitted or cited to the district
    manager during the plan-development process. Prairie State
    contends that the ALJ incorrectly “limited the evidence that
    the District Manager should have considered to the specific
    20
    mine rather tha[n] what was readily available to him.”
    Petitioner Br. 34. It asserts that consideration of practices at
    other mines was necessary both to comport with the plan-
    approval process and to be fair to operators who seek
    approval at new mines of practices already approved
    elsewhere.
    We note that, at least ordinarily, the information relevant
    to the Secretary’s decision will be that which was before the
    agency during the plan-development process. See, e.g., Camp
    v. Pitts, 
    411 U.S. 138
    , 142 (1973) (the “focal point” in
    arbitrary-and-capricious review is “the administrative record
    already in existence”); Ass’n of Private Sector Colls. & Univs.
    v. Duncan, 
    681 F.3d 427
    , 441 (D.C. Cir. 2012) (review is
    “limited to assessing the record that was actually before the
    agency”); James Madison Ltd. ex rel. Hecht v. Ludwig, 
    82 F.3d 1085
    , 1095 (D.C. Cir. 1996). There is no reason to
    believe that expecting operators ordinarily to bring probative
    information to the attention of the front-line agency decision
    maker would encourage them to engage in excessive,
    wasteful, and distracting tactics of bombarding the agency
    with immaterial information.
    We need not decide, however, whether the ALJ abused
    her discretion by declining to consider information that Prairie
    State did not cite in the plan-development process, because
    Prairie State has failed to explain how admission of such
    evidence at the review hearing might have changed the ALJ’s
    decision regarding the reasonableness of the Secretary’s plan.
    See, e.g., PDK Labs. Inc. v. DEA, 
    362 F.3d 786
    , 799 (D.C.
    Cir. 2004) (“If the agency’s mistake did not affect the
    outcome, if it did not prejudice the petitioner, it would be
    senseless to vacate and remand for reconsideration.”). Prairie
    State objects that the ALJ refused to consider “plans that were
    approved at other mines in District 8,” as well as “studies
    21
    conducted in District 8 concerning the taking of 40-foot
    extended cuts.” Petitioner Br. 34. Prairie State does not,
    however, establish the comparability and pertinence of those
    other mines and studies. We therefore lack a basis on which
    to conclude that the proffered evidence might have shown that
    the plan-suitability determinations at Lively Grove were
    arbitrary or impermissibly inconsistent with determinations at
    other mines. Thus, assuming arguendo the ALJ abused her
    discretion by concluding that Prairie State could not rely on
    materials it failed to reference during plan discussions, we
    cannot say that such error harmed Prairie State. See PDK
    Labs., 
    362 F.3d at 799
    .
    2.
    Prairie State argues that the Commission erred by failing
    to reverse as arbitrary and capricious the Secretary’s cut-depth
    determination, which it contends should have authorized
    extended, 40-foot cuts immediately upon the opening of the
    mine. In particular, Prairie State contends that the district
    manager failed to make a mine-specific cut-length
    determination, instead unlawfully treating the cut-length
    guidance expressed in the Secretary’s internal Procedure
    Instruction Letter, No. I08-V-03 (eff. June 6, 2008), as an
    across-the-board, binding rule. That Letter defines as an
    “extended cut” any instance of continuing to dig into a
    working coal face more than twenty feet beyond the last row
    of permanent roof supports without stopping to place
    additional supports in the newly excavated area. J.A. 293.
    The Letter advises against approval of extended cuts until an
    operator has first begun mining with standard, 20-foot cuts, so
    that a new mine’s roof-support and ventilation needs can be
    evaluated under actual operating conditions before extended
    cuts are considered. J.A. 293-98; see Nat’l Mining Ass’n v.
    Sec’y of Labor, 
    589 F.3d 1368
    , 1371-73 (11th Cir. 2009).
    22
    Prairie State argues that, by following the Letter, the district
    manager failed to give mine-specific consideration to the
    merits of its request immediately to begin mining at Lively
    Grove with 40-foot cuts.
    The Commission appropriately concluded, based on the
    record, that the district manager fulfilled his obligation to
    make a mine-specific determination on maximum permissible
    cut length.     The Letter was not an across-the-board,
    substantive requirement, but gave guidance for site-specific
    consideration of operators’ requests for extended cuts. See
    Nat’l Mining Ass’n, 
    589 F.3d at 1370-72
    . The district
    manager testified that he understood the Letter as counseling
    him “to look at developing a 20-foot [cut]” rather than a 40-
    foot cut, J.A. 111, and that an operator “couldn’t get 40-foot
    cuts without going through [the Letter’s] evaluation process,”
    J.A. 112. That directive is consistent with the statutory
    requirement that the Secretary’s plan approvals be based on
    the conditions prevailing at particular mines. See 
    30 U.S.C. §§ 862
    (a), 863(o). Indeed, the thrust of the Letter is to ensure
    that operators and district managers have data from initial
    operating experience at a site to inform the decision about cut
    length appropriate to the mine. The Commission noted that
    the district manager considered evidence that the coal seam at
    Lively Grove was gassy and that starting with shorter cuts
    would allow better methane and dust control. 35 FMSHRC at
    1991-92. It concluded that, in applying the Letter, the district
    manager reasonably exercised informed discretion in light of
    the information available about mine-specific circumstances
    before the mine opened. Id. at 1994-95. We agree that the
    record supports that conclusion.6
    6
    See, e.g., J.A. 105-06 (hearing testimony from roof support
    specialist, on whom the district manager relied, regarding the
    23
    Prairie State similarly contends that the Secretary
    impermissibly applied a binding, across-the-board norm in
    refusing to approve Prairie State’s requested terms governing
    entry widths, diagonals, and ventilation.         The district
    manager, in Prairie State’s view, engaged in “rote
    application” of “District-wide rules,” rather than tailoring the
    plan to the specific conditions prevailing at the mine.
    Petitioner Br. 41-42. Those contentions are not based on the
    Letter as such, as the relevant Letter guidance deals only with
    cut depth, but similarly assert that the district manager
    derogated from his statutory duty to make mine-specific
    suitability determinations.       The record supports the
    Commission’s conclusion, however, that the district manager
    exercised discretion based on substantial evidence of safety
    and health considerations at Lively Grove.7
    practice of starting with 20-foot cuts: “[Y]ou’re trying to make me
    sound like I’m implementing a rule or some sort of regulation. . . . I
    suppose if the mine wanted to address it in another fashion as to
    how they would best support that intersection and protect the miner
    operator in the making of that first cut, that we would certainly look
    at that.”); J.A. 109 (district manager’s testimony that he relied on
    the input of his specialists, inter alia, for information and analysis).
    Once the district manager observed the mine’s initial, safe
    operation with 20-foot cuts, he proceeded to authorize the requested
    extended cuts.
    7
    See, e.g., J.A. 93 (roof support specialist’s testimony that starting
    with 18-foot entry widths was reasonable based on prior
    experience, but no suggestion that he interpreted that starting point
    as required across the board); J.A. 112 (district manager’s
    testimony that approving 18-foot entry width was his standard
    practice, but stating that his decisions were “based upon
    recommendations from” the specialists advising him, and never
    indicating he felt bound by any rule depriving him of discretion).
    24
    3.
    Finally, Prairie State argues that the Commission erred in
    upholding the Secretary’s plan-specific determinations
    regarding cut depth, entry width, diagonals, and ventilation on
    the ground that they were not supported by substantial
    evidence. We disagree. The Commission relied on testimony
    of the district manager and his technical team, as well as
    correspondence and other documentation concerning safety
    and health advantages of the plan terms the district manager
    deemed suitable regarding cut depth, entry width, and
    diagonals. See 35 FMSHRC at 1990-93; 32 FMSHRC at 604-
    10 (ALJ findings and determinations).8 On limited remand,
    the ALJ similarly based her findings regarding ventilation on
    sufficient evidence in the record, and the Commission denied
    further review. 
    35 FMSHRC 3272
    , 3274-75 (Oct. 2013).9
    Prairie State’s other arguments that the Secretary’s
    determinations were arbitrary and capricious or contrary to
    law all lack merit. The Secretary did not ignore, as Prairie
    State asserts, certain alleged safety advantages of extended
    cuts. Rather, as noted above, the agency determined, in
    reasoned fashion and based on substantial evidence, that
    8
    See, e.g., J.A. at 111 (district manager’s conclusion that 20-foot
    cut depths, 18-foot entry widths, and 64-foot diagonals would be
    safer than Prairie State’s proposed corresponding alternatives); J.A.
    103 (roof support specialist’s testimony that 20-foot cuts are safer).
    9
    See, e.g., J.A. at 84 (ventilation specialist’s testimony that 40-foot
    cuts have different impact on ventilation and dust control than 20-
    foot cuts).
    25
    extended cuts were not the safer, prudent practice that should
    initially be implemented at the mine.10

    We deny the petition for review.
