    Before: TATEL * and PILLARD, Circuit Judges; and
    SENTELLE, Senior Circuit Judge.
    Opinion for the Court filed by Senior Circuit Judge
    SENTELLE.
    SENTELLE, Senior Circuit Judge: Appellants brought an
    action contesting a Department of Agriculture rulemaking in
    the district court. There, Appellants argued that the rule
    violated both the Food, Agriculture, Conservation, and Trade
    Act of 1990, as well as the Administrative Procedure Act. The
    district court granted summary judgment in favor of Appellees,
    and Appellants have appealed that decision to this Court. For
    the reasons stated herein, we affirm the district court’s
    judgment in part, reverse it insofar as the challenged rule
    authorizes collecting fees to fund a reserve after 2002, and
    remand for proceedings consistent with this opinion.
    I.     Background
    The Animal and Plant Health Inspection Service
    (“APHIS”) is a federal agency, housed within the Department
    of Agriculture, responsible for administering the Agricultural
    Quarantine and Inspection Program (“Inspection Program”).
    Whenever an international air, rail, truck, or maritime shipment
    arrives at a United States port, APHIS may inspect the
    shipment, vessel, and any passengers for foreign animal and
    plant materials, pests, and diseases.
    Originally, the Inspection Program was funded
    exclusively through congressional appropriations, but in 1990,
    *
    Judge Tatel assumed senior status after this case was argued and
    before the date of this opinion.
    3
    Congress enacted the Food, Agricultural, Conservation, and
    Trade Act (“FACT Act”) of 1990. Pub. L. No. 101-624,
    § 2509, 
    104 Stat. 3359
     (1990) (current version at 21 U.S.C.
    § 136a (2020)). The FACT Act provided for the Inspection
    Program to be, at least in part, funded by user fees rather than
    by appropriations.
    When first enacted, the FACT Act authorized the
    Secretary of Agriculture to collect user fees for only one
    purpose: “to cover the cost of providing agricultural quarantine
    and inspection services . . . .” 21 U.S.C. § 136a(a)(1)(A)
    (1990). Congress modified the Secretary’s authority to collect
    fees in 1996. Pub. L. 104-127, Title IX, § 917, Apr. 4, 1996,
    
    110 Stat. 1187
    . Since then, the statute has authorized the
    Secretary to collect fees to cover three distinct costs. 21 U.S.C.
    § 136a(a)(1) (2020). First, the Secretary may collect fees
    “sufficient to cover the cost of providing agricultural
    quarantine and inspection services . . . .” § 136a(a)(1)(A).
    Second, the Secretary may collect fees “to cover the cost of
    administering this subsection.” § 136a(a)(1)(B). Third, the
    Secretary, “through fiscal year 2002,” is authorized to collect
    fees sufficient “to maintain a reasonable balance in the
    Agricultural Quarantine Inspection User Fee Account . . . .”
    § 136a(a)(1)(C).
    In setting these fees, APHIS must “ensure that the amount
    of the fees is commensurate with the costs of agricultural
    quarantine and inspection services with respect to the class of
    persons or entities paying the fees.” § 136a(a)(2). “The costs of
    the services with respect to passengers as a class includes the
    costs of related inspections of the aircraft or other vehicle.” Id.
    Between 2007 and 2012, APHIS received criticism from
    the Inspectors General of the Departments of Homeland
    Security and Agriculture as well as the Government
    4
    Accountability Office that APHIS was not providing proper
    justification for its fees. In response to this criticism, APHIS
    retained Grant Thornton LLP, an audit, tax, and advisory firm,
    to develop a model to better align fees with costs.
    In a 2012 Report, Grant Thornton proposed new fee levels
    for the various Inspection Program user classes. After
    publishing a proposed rule in 2014, APHIS adopted its final
    rule in 2015 increasing the Commercial Aircraft User Fee to
    $225 for commercial flights and reducing the Commercial Air
    Passenger Fee from $5 to $3.96. Notably, these fees were
    calculated in a way to fund not only the costs of the inspections,
    but also a reserve balance. In the Final Rule, eight user classes
    were exempted from paying any inspection fees at all.
    On May 13, 2016, the Air Transport Association of
    America, Inc. and International Air Transport Association
    (“Appellants”), two air carrier trade associations, filed suit
    against the Department of Agriculture and its Secretary,
    APHIS and its administrator, the Department of Homeland
    Security and its Secretary, and Customs and Border Protection
    and its Commissioner (collectively referred to as “Appellees”
    or “APHIS”) in the district court contesting the Final Rule
    under both the FACT Act and the Administrative Procedure
    Act. In Count I, Appellants asserted that APHIS exceeded its
    Authority under the Act and the APA by charging both a per-
    passenger and a per-aircraft fee to fund inspections of a single
    aircraft. In Count II, Appellants alleged that the Final Rule
    violated the FACT Act by imposing incommensurately high
    fees—the surplus from which allegedly cross-subsidized non-
    fee-paying exempt user class inspections—and violated the
    APA by failing to explain how the $225 Commercial Aircraft
    User Fee was “commensurate” with inspection costs, or
    necessary at all given the Commercial Air Passenger Fee. In
    Count III, Appellants alleged that the Final Rule’s imposition
    5
    of a reserve surcharge exceeded the authority granted to the
    Secretary because the Act authorized a reserve charge until
    only 2002. Finally, in Count IV, Appellants alleged that the
    Final Rule violated the APA because APHIS withheld key
    information during the rulemaking.
    APHIS responded, asserting, among other things, that
    despite the time limitation in 21 U.S.C. § 136a(a)(1)(C), it
    retained the authority to collect fees to fund a reserve under that
    subparagraph past fiscal year 2002. Ultimately, the district
    court granted summary judgment on Counts I, II, and IV in
    favor of Appellees. Air Transp. Assoc. of Am., Inc. v. United
    States Dep’t of Agric., 
    303 F. Supp. 3d 28
    , 57 (D.D.C. 2018).
    As for Count III, the district court held that due to the time
    limitation, subparagraph (a)(1)(C) does not authorize APHIS
    to collect fees to fund a reserve after fiscal year 2002 and
    granted summary judgment on Count III in favor of Appellants.
    Id. at 52. The district court then remanded the reserve surcharge
    portion of the rulemaking for further consideration and possible
    rulemaking by APHIS. Id. at 57.
    On remand, APHIS issued a final interpretive rule insisting
    that even if it no longer had the authority to collect a reserve
    surcharge under § 136a(a)(1)(C), it retained the authority to
    collect a reserve surcharge under §§ 136a(a)(1)(A), (B).
    Appellants then amended their original complaint, challenging
    APHIS’s new rationalization for collecting a reserve surcharge.
    Ultimately, the district court granted summary judgment in
    favor of Appellees, holding that subparagraphs (A) and (B)
    support APHIS’s authority to collect a reserve surcharge
    despite the expiration of the explicit authorization to do so in
    subparagraph (C). Air Transport Assoc. of Am., Inc. v. Dep’t of
    Agric., Case No. 1:16-cv-00919-PLF, 
    2021 WL 1166928
    , at
    *14 (D.D.C. March 26, 2021). Appellants timely appealed the
    district court’s decisions to this Court.
    6
    We have jurisdiction over this appeal under 
    28 U.S.C. § 1291
    . We review the district court’s grant of summary
    judgment de novo. AquAlliance v. United States Bureau of
    Reclamation, 
    856 F.3d 101
    , 104 (D.C. Cir. 2017).
    II.      Analysis
    Appellants contest four aspects of the Final Rule: (1) that
    the collection of a reserve surcharge violates the FACT Act; (2)
    that the Final Rule violates the FACT Act’s prohibition on
    cross-subsidization; (3) that the Final Rule violates the FACT
    Act and the APA by charging both a per-passenger and a per-
    aircraft fee on one aircraft; and (4) that APHIS violated the
    APA by withholding certain information during the rulemaking
    process.
    A. The Reserve Surcharge
    In its 1996 amendments to the FACT Act, Congress
    clarified when APHIS is permitted to collect user fees: (A) “to
    cover the cost of providing agricultural quarantine and
    inspection services”; (B) “to cover the cost of administering
    this subsection”; and (C) “through fiscal year 2002, to maintain
    a reasonable balance in the Agricultural Quarantine Inspection
    User Fee Account . . . .” §§ 136a(a)(1)(A)-(C). Appellants’
    argument regarding the reserve surcharge is quite simple: the
    authority to collect fees sufficient to maintain a reserve in
    § 136a(a)(1)(C) expired after fiscal year 2002, and therefore
    the Final Rule violates the FACT Act by continuing to do so.
    APHIS would have us read § 136a(a)(1)(C) in conjunction with
    §§ 136a(a)(5)-(6) to mean that between 1990 and 2002,
    Congress explicitly authorized APHIS to collect fees to
    maintain a reserve in the User Fee Account and that after 2002,
    Congress authorized APHIS to collect fees to maintain a
    7
    reserve in its own account by saying nothing at all. This blinks
    reality. The text’s plain meaning and applicable canons of
    statutory construction support Appellants’ reading of the
    statute.
    Appellants’ argument raises a question of statutory
    interpretation. We review an agency’s interpretation of a
    statute using the familiar Chevron framework. Chevron,
    U.S.A., Inc. v. Natural Def. Council, Inc., 
    467 U.S. 837
    , 843–
    44 (1984). In Step One of the Chevron analysis, we apply
    ordinary tools of statutory construction to determine “whether
    Congress has directly spoken to the precise question at issue.”
    Merck & Co., Inc. v. United States Dep’t of Health & Human
    Servs., 
    962 F.3d 531
    , 535 (D.C. Cir. 2020) (citation omitted).
    Should we conclude that the statute does speak to the matter at
    hand, our analysis ends there. However, if the statute is
    ambiguous, we defer to an agency’s interpretation of the statute
    so long as it is reasonable. Id. at 536.
    In this case, the question at issue is whether the FACT Act
    authorizes APHIS to collect a reserve surcharge after fiscal
    year 2002. Appellants offer that Congress spoke to this issue in
    § 136a(a)(1)(C), where it stated that APHIS had the authority
    to collect fees to maintain a reserve “through fiscal year 2002.”
    APHIS counters that subparagraph (a)(1)(C) functioned
    independently to specify the location for storing the reserve
    surcharge—the “Agricultural Inspection User Fee Account”—
    through 2002, rather than merely speaking to the authority to
    collect fees. Therefore, APHIS argues that Congress only
    limited the location for the surcharge funds after 2002 and not
    the agency’s authority to collect them, and that we must defer
    to its interpretation of the FACT Act so long as it is reasonable.
    APHIS contends that the authority to continue collecting a
    reserve fee after 2002 exists in subparagraphs (a)(1)(A)-(B)
    8
    and that (a)(1)(C) is of no consequence now that fiscal year
    2002 has come and gone. But this reading of the statute
    conflicts with its plain meaning and violates the canon against
    surplusage. “It is a familiar canon of statutory construction that,
    ‘if possible’, we are to construe a statute so as to give effect to
    ‘every clause and word.’” Amoco Production Co. v. Watson,
    
    410 F.3d 722
    , 733 (D.C. Cir. 2005) (quoting United States v.
    Menasche, 
    348 U.S. 528
    , 538–39 (1955)). Surplusage can
    significantly weaken a Chevron Step One argument. See
    N.L.R.B. v. Fed. Labor Relations Auth., 
    952 F.2d 523
    , 532
    (D.C. Cir. 1992).
    Per APHIS’s reading of the statute, its authority to collect
    a fee to fund a reserve in its account is included in the authority
    to collect fees covering the cost of providing services,
    § 136a(a)(1)(A), and “the cost of administering this
    subsection,” § 136a(a)(1)(B). If we were to accept this reading,
    then APHIS would have always had, and will always have, the
    authority to collect fees to fund a reserve balance in its account
    unless the statute is amended to say otherwise. Were this the
    case, subparagraph (a)(1)(C), which explicitly limits APHIS’s
    authority to collect fees to fund a reserve through fiscal year
    2002, would be rendered meaningless.
    APHIS’s argument that subparagraph (a)(1)(C) merely
    specifies that the reserve will be housed in the Agricultural
    Quarantine Inspection User Fee Account (“the User Fee
    Account”) through fiscal year 2002 does not rescue it from this
    death knell. Rather, §§ 136a(a)(5)-(6), which created and
    regulated the User Fee Account, provide further support to our,
    and therefore Appellants’, reading of subparagraph (a)(1)(C).
    Subparagraph (a)(5) established the User Fee Account and
    provides that its funds were to be used “to cover the costs
    associated with the provision of agricultural quarantine and
    inspection services and the administration of this subsection”
    9
    through fiscal year 2002. § 136a(a)(5)(B). Subparagraph (a)(6)
    provides that after fiscal year 2002, all remaining funds in the
    User Fee Account were to be transferred to Department of
    Agriculture accounts that incur the costs of running the
    Inspection Program. § 136a(a)(6).
    Congress spoke to the question of whether APHIS could
    collect fees to fund a reserve in subparagraph (a)(1)(C). It
    specified when APHIS was allowed to do so (through fiscal
    year 2002) and where that reserve should be housed (the User
    Fee Account). We will not read meaning into statutory silence
    when Congress has demonstrated that it is perfectly capable of
    delegating this authority to APHIS when it so chooses. Accord
    D. Ginsberg & Sons v. Popkin, 
    285 U.S. 204
    , 208 (1932)
    (“General language of a statutory provision, although broad
    enough to include it, will not be held to apply to a matter
    specifically dealt with in another part of the same enactment.”);
    RadLAX Gateway Hotel, LLC v. Amalgamated Bank, 
    566 U.S. 639
    , 645 (2012).
    Appellants’ reading of the statute is further supported by
    the FACT Act’s revision history. When originally enacted, the
    authority to collect fees to maintain a reasonable balance in the
    User Fee Account did not include the “through fiscal year
    2002” limitation. Pub. L. 101-624, Title XXV, § 2509, Nov.
    28, 1990, 104 Stat. at 4069, 4071. The time limitation was
    added to APHIS’s authority to collect fees for maintaining a
    reserve in the 1996 amendments to the FACT Act. Pub. L. 104-
    127, Title IX, § 917, Apr. 4, 1996, 110 Stat. at 1187. That the
    time limitation was added to the statute after its original
    enactment supports the idea that Congress meant to sunset the
    authority it delegated to APHIS to collect fees to fund a reserve
    after fiscal year 2002.
    10
    Congress has directly addressed the question of whether
    APHIS may continue to collect fees to fund a reserve after
    fiscal year 2002. They may not do so. We will remand this case
    to the district court for vacating insofar as the Final Rule
    authorizes collecting fees to maintain a reserve account.
    Appellants’ other arguments do not fare so well.
    B. The Aircraft Fees
    Under the Final Rule, it is possible for inspections of a
    single aircraft to be funded by two different fees. The
    Commercial Aircraft User Fee is charged to all arriving
    international commercial aircraft with more than 64 seats. The
    Commercial Air Passenger Fee is charged to passengers
    arriving on international commercial aircraft. Commercial
    aircraft are subject to the Commercial Aircraft User Fee
    regardless of whether a particular flight is carrying cargo.
    Appellants contend that charging both fees to the same
    arriving aircraft violates the FACT Act’s requirement that
    APHIS “ensure that the amount of [Inspection Program] fees is
    commensurate with the costs of agricultural quarantine and
    inspection services with respect to the class of persons or
    entities paying the fees,” 21 U.S.C. § 136a(a)(2), because “[t]he
    costs of the services with respect to passengers as a class
    includes the costs of related inspections of the aircraft or other
    vehicle,” id. APHIS argues that this challenge to the Final Rule
    is time barred, as it comes more than “six years after the right
    of action first accrue[d].” 
    28 U.S.C. § 2401
    (a). But since the
    time bar is non-jurisdictional and does not change our
    conclusion, we need not address it. See Jackson v. Modly, 
    949 F.3d 763
    , 778 (D.C. Cir. 2020) (“[W]e hold that § 2401(a)’s
    time bar is nonjurisdictional and subject to equitable tolling.”).
    Therefore, we proceed to the merits of this argument.
    11
    1. The Costs of “Related” Inspections
    Section 136a(a)(2) requires that APHIS “ensure that the
    amount of [Inspection Program] fees is commensurate with the
    costs of agricultural quarantine and inspection services with
    respect to the class of persons or entities paying the fees.” 21
    U.S.C. § 136a(a)(2). Further, “[t]he costs of the services with
    respect to passengers as a class includes the costs of related
    inspections of the aircraft or other vehicle.” Id.
    Our review of agency statutory interpretation, like the
    reserve fee issue above, is governed by the Chevron
    framework. First, we look to whether Congress has directly
    addressed the question at issue in the statute. If it has not, we
    defer to an agency’s interpretation of the statute so long as it is
    reasonable. Chevron, U.S.A., Inc. v. Natural Def. Council, Inc.,
    
    467 U.S. 837
    , 843–44 (1984).
    Appellants contend that Congress has spoken precisely to
    the issue of whether a single aircraft may be subject to both
    fees in the statute and that the analysis should conclude at
    Chevron Step One. We agree that the analysis concludes at
    Chevron Step One, but we disagree with Appellants’ ultimate
    conclusion.
    The construction of this statute hinges on the word
    “related” in § 136a(a)(2)’s “[t]he costs of the services with
    respect to passengers as a class includes the costs of related
    inspections of the aircraft or other vehicle.” Appellants aver
    that because the section requires that passengers be responsible
    for the costs of “related inspections of the aircraft,” those
    passengers are responsible for the costs of inspecting the entire
    aircraft. But this reading of the statute would give no meaning
    to the word “related” in the statute. Appellants’ reading would
    not change if “related” were deleted from the statute.
    12
    As above, we “construe a statute so as to give effect to
    ‘every clause and word.’” Amoco Production Co. v. Watson,
    
    410 F.3d 722
    , 733 (D.C. Cir. 2005) (quoting United States v.
    Menasche, 
    348 U.S. 528
    , 538–39 (1955)). We will not interpret
    a statute to be read the same way regardless of whether a
    substantive term is included in the reading. In this statute,
    “related” performs an important narrowing function. “Related”
    is defined as “[c]onnected by reason of an established or
    discoverable relation,” Related, def. 1, Merriam-Webster’s
    Unabridged Dictionary (2022), and “[c]onnected in some way;
    having relationship to or with something else,” Related,
    Black’s Law Dictionary (11th ed. 2019).
    The inclusion of “related” in the statute clearly limits
    which inspections commercial air passengers are responsible
    for funding. This statute does not say that they are responsible
    for the costs of the inspection of the entire aircraft; they are
    responsible for the costs of inspections related to themselves
    and their presence on the aircraft. This is further supported by
    the use of the plural “inspections” in the statute. 21 U.S.C.
    § 136a(a)(2). Clearly, Congress contemplated that a single
    aircraft could undergo multiple inspections and would not
    necessarily be subject to one single inspection paid for by one
    single user class. Congress has spoken to the question of
    whether APHIS may charge different user classes for different
    inspections of a single vehicle, and therefore our analysis of
    whether the application of both fees violates the FACT Act
    ends here. However, even if the statute were ambiguous,
    APHIS’s interpretation of the statute is reasonable, and
    Appellants’ challenge of the application of both fees would fail
    at Chevron Step Two as well.
    13
    2. The Application of Both Fees and the APA
    Appellants further contend that the imposition of a
    Commercial Aircraft User Fee on aircraft with passengers
    paying a Commercial Air Passenger Fee is arbitrary and
    capricious because the Grant Thornton analysis did not support
    the imposition of both fees and APHIS failed to explain why it
    deviated from this recommendation. We will hold an agency
    action unlawful and set it aside when it is “arbitrary, capricious,
    an abuse of discretion, or otherwise not in accordance with
    law.” 
    5 U.S.C. § 706
    (2)(A). In rulemaking, an agency must
    “examine the relevant data and articulate a satisfactory
    explanation for its action including a ‘rational connection
    between the facts found and the choice made.’” Motor Vehicle
    Mfrs. Ass’n of the U.S., Inc. v. State Farm Mut. Auto Ins. Co.,
    
    463 U.S. 29
    , 43 (1983) (quoting Burlington Truck Lines v.
    United States, 
    371 U.S. 156
    , 168 (1962)).
    a. The Grant Thornton Analysis
    According to Appellants, APHIS acted arbitrarily and
    capriciously because the reports prepared by Grant Thornton,
    which were relied upon in establishing the Final Rule, assumed
    that individual aircraft would be assessed only the Commercial
    Air Passenger Fee if they carried passengers, and APHIS
    neither acknowledged this nor explained why it rejected this
    assumption in the Final Rule. However, no explanation was
    necessary because Appellants misconstrue the Grant Thornton
    reports. Appellants’ argument emphasizes statements
    throughout the Grant Thornton reports that appear to indicate
    that the Commercial Air Passenger Fee would cover the cost of
    inspecting the entirety of the aircraft. JA 510; JA 373–74; JA
    356. However, as argued by APHIS and found by the district
    court, these statements and distinctions do not tell the entire
    story. Grant Thornton’s calculations of fee amounts clearly
    14
    presume that APHIS will continue funding inspections of
    arriving aircraft by charging both the Commercial Aircraft
    User Fee and the Commercial Air Passenger Fee. APHIS relied
    on this methodology when promulgating the Final Rule.
    The Final Rule bears this out. In both the Grant Thornton
    documentation and the Final Rule, the Commercial Aircraft
    User Fee was calculated by dividing the total costs of
    inspecting Commercial Aircraft by the total number of
    Commercial Aircraft (cargo-only and aircraft with passengers).
    See JA 471–72 (Grant Thornton Model Documentation stating
    that there were 139,798 cargo-only aircraft and 517,629
    commercial aircraft in Fiscal Year 2010 totaling 657,427 total
    aircraft); JA 244 (Final Rule listing costs and calculating the
    Commercial Aircraft User Fee based on 657,427 aircraft in
    Fiscal Year 2010). Had Grant Thornton included only the
    139,798 cargo-only aircraft in its calculation of the
    Commercial Aircraft User Fee, its proposed fee would have
    been hundreds of dollars higher than the $225 fee it did
    propose.
    All of Appellants’ arguments regarding the dual
    application of the Commercial Aircraft User Fee and the
    Commercial Air Passenger Fee fail.
    C. Cross-subsidization
    Appellants further argue that the Final Rule violates the
    FACT Act by permitting two forms of unlawful cross-
    subsidization. First, Appellants claim that the Final Rule
    overcharges certain user classes to pay for the inspections of
    user classes that are exempt from being charged for
    inspections. Second, Appellants contend that APHIS is
    improperly comingling fees collected from various user classes
    15
    into a single account that funds the inspections of all user
    classes.
    Appellants’ ground their cross-subsidization arguments in
    the FACT Act’s “commensurate” requirement. Per the FACT
    Act, APHIS must “ensure that the amount of the fees is
    commensurate with the costs of agricultural quarantine and
    inspection services with respect to the class of persons or
    entities paying the fees.” 21 U.S.C. § 136a(a)(2). The district
    court concluded that APHIS had not engaged in any “cross-
    subsidization” that would violate this requirement. Air Transp.
    Assoc. of Am., Inc. v. United States Dep’t of Agric., 
    303 F. Supp. 3d 28
    , 52–54 (D.D.C. 2018). First, the court found no
    violation where APHIS provided fee-exempt inspections to
    certain user classes because those inspections were paid for by
    appropriations. 
    Id.
     at 52–53. Second, the court held that APHIS
    could fund inspections for fee-paying user classes from an
    account that comingled fees collected from multiple user
    classes so long as “the fees charged” were commensurate to
    costs because the FACT Act “instructs the Secretary on how to
    set the fees, not how to use [them].” Id. at 53; see id. at 53–54.
    Appellants challenge both of those conclusions, and APHIS
    defends them.
    There are eight user classes of the Inspection Program that
    are exempt from paying any fees at all. These are private
    vehicles, pedestrians, buses, private vessels, private aircraft,
    military inspections, rail passengers, and passenger aircraft
    with 64 or fewer seats. While all are subject to the same
    inspections as other Inspection Program users, they are not
    required to pay for the service. APHIS offers that the
    inspections for these exempted user classes are funded through
    congressional appropriations.
    16
    Appellants have two overarching arguments about that
    form of alleged cross-subsidization. First, Appellants aver that
    any reliance on appropriations violates Congress’s intent that
    the Inspection Program be self-funded through user fees rather
    than through appropriations. Second, they argue that the record
    does not support that any supposed appropriations cover the
    costs of the inspections for exempted user classes. But these
    arguments rely on a distorted interpretation of the FACT Act
    and cannot succeed.
    Appellants argue that the use of appropriations to fund
    inspections of the exempt user classes is contrary to the FACT
    Act because it prohibits the use of appropriations to fund the
    Inspection Program. This is not the case. There is no language
    in the Act that prohibits APHIS from funding parts of the
    Inspection Program via appropriations. The FACT Act
    provides that APHIS “may prescribe and collect fees . . . .” 21
    U.S.C. § 136a(a)(1) (emphasis added). There is no requirement
    in the FACT Act that APHIS actually do so, and therefore,
    certainly no requirement that APHIS cover all of its costs
    through user fees.
    Further, the record demonstrates that no such cross-
    subsidization is occurring. According to the record before us,
    the cost of providing inspection services to the exempted user
    classes makes up approximately 24% of all Inspection Program
    costs. Appellant Opening Br. 47 (citing JA 17–18, 237). Per
    APHIS’s Regulatory Impact & Final Regulatory Flexibility
    Analysis, appropriations were expected to cover up to 30% of
    total inspection costs. JA 149. Therefore, the funds received
    through appropriations are more than sufficient to cover the
    costs of inspecting the exempted user classes.
    Appellants’ argument that APHIS may not comingle funds
    collected from various user classes into a single account fails
    17
    as well. The statute does not include any prohibition on funds
    collected from one user class being used to fund inspections of
    another fee-paying user class. The section containing the
    “commensurate” language is a limitation on how much can be
    collected in fees from a particular user class. It is not a
    limitation on how those fees may be spent. Therefore,
    Appellants’ argument that fees collected from multiple user
    classes cannot be comingled in a fund that pays for the
    inspections of fee-paying user classes fails because the FACT
    Act does not prohibit this form of cross-subsidization. The
    district court reached this same conclusion. Air Transp., 303 F.
    Supp. 3d at 53–54.
    D. The Withheld Information
    Appellants’ final argument is that APHIS violated the
    APA by relying on unreleased information. Specifically,
    Appellants contend that APHIS violated the APA by
    withholding underlying Grant Thornton fee model
    documentation that was central to its analysis and the Final
    Rule.
    The APA requires that “interested persons” have “an
    opportunity to participate in the rule making through
    submission of written data, views, or arguments with or
    without opportunity for oral presentation.” 
    5 U.S.C. § 553
    (c).
    We have interpreted this requirement to mean that an agency
    must make “at least the most critical factual material that is
    used to support the agency’s position on review” public.
    Association of Data Processing Serv. Orgs., Inc. v. Board of
    Governors of the Fed. Reserve Sys., 
    745 F.2d 677
    , 684 (D.C.
    Cir. 1984). “[A]n agency cannot rest a rule on data that, in
    critical degree, is known only to the agency.” Time Warner
    Entm’t Co. v. FCC, 
    240 F.3d 1126
    , 1140 (D.C. Cir. 2001). To
    succeed on this argument, Appellants must demonstrate that
    18
    they were prejudiced by the withholding of this data. They do
    not need to prove that their comments would have changed the
    terms of the Final Rule, only that they “had something useful
    to say about this critical data.” Chamber of Commerce v. SEC,
    
    443 F.3d 890
    , 905 (D.C. Cir. 2006). But if Appellants cannot
    produce “substantive challenges which differ in kind from the
    original comments,” then no harm has occurred. Florida Power
    & Light Co. v. United States, 
    846 F.2d 765
    , 772 (D.C. Cir.
    1988).
    Appellants contend that they were denied a meaningful
    chance to comment on the rulemaking because APHIS did not
    release the underlying Grant Thornton fee model
    documentation, JA 304–496, and cost output data, AR 656–
    69780, before promulgating the Final Rule. According to
    Appellants, this additional information would have further
    supported their position that Grant Thornton did include the
    costs of inspecting the entire aircraft in its calculation of the
    Commercial Air Passenger Fee, which we held not to be the
    case above.
    In this case, after receiving the withheld information,
    Appellants have provided no arguments substantively different
    from their original arguments. Appellants argue that they
    would have been able to further support their arguments that
    APHIS violated the APA in the Final Rule by applying the
    Commercial Aircraft User Fee and the Commercial Air
    Passenger fee to arriving passenger aircraft. But Appellants
    point to the information that they were denied only once in their
    brief. Appellant Br. 42. Appellants use this information merely
    to provide additional support for their argument that Grant
    Thornton always intended for the Commercial Air Passenger
    Fee to cover the costs of inspecting the entire aircraft. This is
    not substantively different than the arguments made prior to
    their receipt of this information.
    19
    Appellants have not shown a harm from the withholding
    of this data. Therefore, the failure to release the requested data
    prior to the promulgation of the Final Rule did not violate the
    APA.
    III.    Conclusion
    For the reasons stated above, we affirm the district court’s
    judgment in part, reverse it insofar as the challenged rule
    authorizes collecting fees to fund a reserve after 2002, and
    remand for proceedings consistent with this opinion.
