    This case concerns the valuation of royalties to be paid on carbon dioxide
    (“CO2”) produced from federal oil and gas leases now owned by OXY USA, Inc.
    (“OXY”). OXY appeals the decision of the U.S. Department of the Interior’s Office
    of Natural Resources Revenue (“ONRR”) ordering it to pay an additional
    $1,820,652.66 in royalty payments on federal gas leases that are committed to the
    Bravo Dome Unit (“the Unit”). Under the Mineral Leasing Act, federal lessees must
    pay royalties of at least 12.5 percent on the value of the CO2 removed or sold from
    their lease properties. When lessees sell their gas in arm’s-length transactions, 1 the
    sales price can generally be used to determine value for royalty purposes. But during
    the relevant audit period, the owner of the leases OXY subsequently acquired—
    Amerada Hess Corporation (“Hess”)—used almost all of the CO2 it produced in the
    Unit for its own purposes rather than sale. 2
    Following an audit, ONRR rejected Hess’s valuation method and established
    its own. Hess appealed, and ONRR’s Director issued a decision reducing the amount
    Hess owed but affirming the remainder of ONRR’s order. Hess appealed to the
    1
    Arm’s-length transactions involve contracts or agreements that have been
    arrived at in the marketplace between independent, nonaffiliated persons with
    opposing economic interests regarding those contracts. 
    30 C.F.R. § 206.151
    .
    2
    During the relevant audit period, Hess was the lessee of the federal leases at
    issue in this appeal. OXY obtained the leases from Hess in 2017, after ONRR’s
    order was issued. Unless otherwise indicated herein, we refer to Hess for time
    periods before 2017 and to OXY for later periods. Beyond the leases OXY acquired
    from Hess, OXY holds other federal Unit leases, but they are not at issue in this case
    because the agency’s decision does not cover them.

    prior to the 33-month limitations period. On appeal to the United States District
    Court for the District of New Mexico, the district court rejected OXY’s challenge to
    the amount of royalties owed and affirmed the Director’s decision.
    Exercising jurisdiction under 
    28 U.S.C. § 1291
    , we affirm.
    I
    A.    Statutory and Regulatory Background
    1.     Mineral Leasing Act of 1920 and Federal Oil and Gas Royalty
    Management Act of 1982
    The Mineral Leasing Act of 1920 regulates the leasing of public lands for
    developing deposits of federally owned coal, petroleum, natural gas, and other
    minerals. 
    30 U.S.C. § 181
     et seq. Lessees must pay a royalty “at a rate of not less
    than 12.5 percent in amount or value of the production removed or sold from the
    lease.” 
    30 U.S.C. § 226
    (b)(1)(A).
    In 1982, Congress passed the Federal Oil and Gas Royalty Management Act in
    order “to ensure the prompt and proper collection and disbursement of oil and gas
    revenues.” H.R. Rep. No. 97-859, at *1 (1982). The Act directs the Secretary of the
    Interior to “establish a comprehensive inspection, collection and fiscal and
    production accounting and auditing system” to determine and collect oil and gas
    royalties. 
    30 U.S.C. § 1711
    (a). The Secretary of the Interior also is required to
    “audit and reconcile, to the extent practicable, all current and past lease accounts for
    3
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022     Page: 4
    leases of oil or gas and take appropriate actions to make additional collections or
    refunds as warranted.” § 1711(c)(1).
    2.     ONRR’s 1988 Valuation Regulations
    The regulations in effect during the relevant period were issued by the Interior
    Department’s Minerals Management Service in 1988 and codified at 
    30 C.F.R. § 206
    . 3 See 
    53 Fed. Reg. 1230
     (Jan. 15, 1988). The regulations provide that with
    narrow exceptions, if a lessee disposed of its production pursuant to an arm’s-length
    contract, the gross proceeds accruing to the lessee under that contract determine the
    value of the gas for royalty purposes. 
    30 C.F.R. §§ 206.152
    (b)(1)(i)–(iv). For gas
    production not disposed of pursuant to an arm’s-length contract, the lessee must
    value its gas pursuant to the “first applicable” of three possible benchmarks:
    (1) The gross proceeds accruing to the lessee pursuant to a sale under its
    non-arm’s-length contract (or other disposition other than by an
    arm’s-length contract), provided that those gross proceeds are
    equivalent to the gross proceeds derived from, or paid under,
    comparable arm’s-length contracts for purchase, sales, or other
    dispositions of like-quality gas in the same field (or, if necessary to
    obtain a reasonable sample, from the same area). In evaluating the
    comparability of arm’s-length contracts for the purposes of these
    regulations, the following factors shall be considered: price, time of
    execution, duration, market or markets served, terms, quality of gas,
    volume, and such other factors as may be appropriate to reflect the
    value of the gas.
    3
    In 2010, ONRR replaced the Minerals Management Service, and the
    regulations at 
    30 C.F.R. § 206
     were redesignated as 
    30 C.F.R. § 1206
     without
    material change. See 
    75 Fed. Reg. 61,051
     (Oct. 4, 2010). The regulations have since
    been amended further and are the subject of both litigation and additional proposed
    rulemaking, but none of these subsequent developments are relevant to this case. For
    consistency, we cite to the 1988 regulations using the 
    30 C.F.R. § 206
     citations.
    4
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022       Page: 5
    (2) A value determined by consideration of other information relevant in
    valuing like-quality gas, including gross proceeds under arm’s-length
    contracts for like-quality gas in the same field or nearby fields or areas,
    posted prices for gas, prices received in arm’s-length spot of sales of
    gas, other reliable public sources of price or market information, and
    other information as to the particular lease operation or the saleability of
    the gas; or
    (3) A net-back method or any other reasonable method to determine
    value.
    §§ 206.152(c)(1)–(3). Put another way, if gas is not sold pursuant to an arm’s-length
    contract but is sold pursuant to an equivalent non-arm’s-length contract, the lessee
    must value its gas pursuant to the first regulatory benchmark. 4 If gas is not sold
    pursuant to an arm’s-length contract or an equivalent non-arm’s-length contract (as
    in OXY’s case), a lessee must turn to the second regulatory benchmark, which is
    more open-ended. § 206.152(c)(2).
    After a lessee calculates the value of gas, ONRR allows the lessee to take a
    transportation allowance, or “a deduction for the reasonable actual costs incurred by
    the lessee to transport unprocessed gas, residue gas, and gas plant products from a
    lease to a point off the lease.” § 206.156(a). The regulations clarify that “[t]he
    lessee must place gas in marketable condition . . . at no cost to the Federal
    Government,” which means that the lessee cannot include the costs required to place
    the gas in marketable condition in the transportation allowance. § 206.152(i)
    4
    The parties do not dispute ONRR’s conclusion that the first regulatory
    benchmark does not apply because Hess took the majority of its CO2 production from
    the Unit in-kind and did not accrue gross proceeds under a non-arm’s-length contract.
    5
    Appellate Case: 21-2011     Document: 010110678144        Date Filed: 05/02/2022        Page: 6
    (emphasis added). All transportation allowances deducted under a non-arm’s-length
    or no contract situation are subject to ONRR’s monitoring, review, audit, and
    adjustment, and the agency “may direct a lessee to modify its estimated or actual
    transportation allowance deduction.” § 206.157(b).
    In determining a non-arm’s-length transportation allowance, a lessee also may
    include certain “allowable costs.” § 206.157(f). The regulations directly address the
    two costs at issue in OXY’s case: compression and dehydration. 5 The regulations
    allow a lessee to include “[s]upplemental costs for compression, dehydration, and
    treatment of gas . . . only if such services [1] are required for transportation and
    [2] exceed the services necessary to place production into marketable condition.”
    § 206.157(f)(9) (emphasis added).
    All royalty payments then are subject to ONRR’s audit and adjustment, and
    ONRR “will direct a lessee to use a different value if it determines that the reported
    value is inconsistent with the requirements of these regulations.” §§ 206.150(c),
    206.152(e)(1).
    An important feature of the regulations at issue in this case is that “[i]f the
    specific provisions of any [Federal oil or gas lease] . . . are inconsistent with any
    regulation [applicable to the gas production from Federal oil and gas leases], then the
    lease . . . shall govern to the extent of that inconsistency.” § 206.150(b). The
    5
    Compression and dehydration are processes that remove unacceptable liquids
    and impurities from natural gas extracted from the ground and prepare the gas for
    safe transport and use.
    6
    Appellate Case: 21-2011    Document: 010110678144         Date Filed: 05/02/2022      Page: 7
    regulations explain that their purpose “is to establish the value of production for
    royalty purposes consistent with . . . lease terms” and they “are intended to ensure
    that the administration of oil and gas leases is discharged in accordance with the
    requirements of the governing mineral leasing laws and lease terms.” §§ 206.150(a),
    (d). In short, the relevant regulations are meant to be applied as follows: If the
    regulation is inconsistent with a lease, then the lease governs to the extent of that
    inconsistency.
    B.    Factual and Procedural Background
    1.     The Bravo Dome Unit and Unit Agreement
    Hess produced CO2 from numerous federal leases (“Leases”) in Harding,
    Quay, and Union Counties in northern New Mexico. 6 Under the Leases’ terms, Hess
    agreed to pay the United States, as lessor, “12 ½ percent royalty on the production
    removed or sold from the leased lands computed in accordance with the Oil and Gas
    Operating Regulations (30 C.F.R. Pt. 221).” ROA, at 442b, 446b, 450b, 454b
    [Sec. 2(d)(l)]. The Leases further state:
    It is expressly agreed that the Secretary of the Interior may establish
    reasonable minimum values for purposes of computing royalty on any
    or all oil, gas, natural gasoline, and other products obtained from gas,
    due consideration being given [1] to the highest price paid for a part or
    for a majority of production of like quality in the same field, [2] to the
    price received by the lessee, [3] to posted prices, and [4] to other
    relevant matters and, whenever appropriate, after notice and opportunity
    to be heard.
    6
    The record contains a total of four Leases, and their relevant terms are
    identical. See ROA, at 442, 446, 450, 454.
    7
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022       Page: 8
    Id. [Sec. 2(d)(2)] (“Lease valuation factors”). The Leases clarified that Hess was
    “subject to any unit agreement heretofore or hereafter approved by the Secretary of
    the Interior, the provisions of said agreement to govern the lands subject thereto
    where inconsistent with the terms of this lease.” Id. at 442a, 446a, 450a, 454a
    [Sec. 1].
    Bravo Dome is a natural carbon source field located in northeastern New
    Mexico. In 1979, the Bravo Dome Unit was formed under the Bravo Dome Carbon
    Dioxide Unit Agreement (“Unit Agreement”) to consolidate and coordinate CO2
    production from a number of both federal and non-federal leases in the Bravo Dome
    area, including Hess’s Leases. Id. at 415–40. Under the terms of the Unit
    Agreement, once the Unit Operator allocated CO2 to each tract in the Unit, each
    working-interest owner 7 remitted payment to its royalty-interest owners. Id. at 429
    [§ 6.3]. The original Unit Operator was Amoco Production Company (“Amoco”),
    but Amoco’s successor-in-interest OXY was the Unit Operator during the relevant
    audit period.
    The Unit Agreement modified the underlying Leases to the extent of any
    inconsistencies, and it incorporated the federal oil and gas operating regulations
    “provided such regulations are not inconsistent with the terms of this Agreement.”
    Id. at 417, 424 [§ 3.3], 438 [§ 15.1]. The Unit Agreement also attempted to modify
    A working-interest owner is someone who owns the right to search, develop,
    7
    and produce oil and gas on the leased property as well as pay all costs. ROA, at 219.
    8
    Appellate Case: 21-2011    Document: 010110678144         Date Filed: 05/02/2022       Page: 9
    the royalty clauses in the Leases committed to the Unit in two ways. First, royalty
    was due on CO2 at “the standard conditions of measurement for natural gases which
    are at 60° Fahrenheit and 15.025 pounds per square inch absolute [‘psia’] pressure
    base.” Id. at 429 [§ 6.2]. Second, the Unit Agreement attempted to amend the
    royalty clauses to base royalty payments on the higher of “(a) the net proceeds
    derived from the sale of Carbon Dioxide Gas at the well whether such sale is to one
    or more of the parties to this agreement or to any other party or parties; or (b) a
    minimum value at the well of twelve cents per thousand cubic feet ($0.12/mcf).” Id.
    [§ 6.3].
    For the Unit Agreement to be effective, Amoco was required to submit it to the
    United States Geological Survey (“USGS”) for approval. 8 On August 29, 1980,
    USGS approved the Unit Agreement, with a few exceptions. Id. at 465. In the
    Determination approving the Unit Agreement, USGS certified that the Unit
    Agreement modified the Leases’ terms to the extent of any inconsistencies. Id. But
    USGS excluded some provisions of the Unit Agreement from its approval, the
    relevant exclusion being § 6.3(b)—the twelve cents per thousand cubic feet minimum
    value. Id. The Determination stated that “the provisions of Article 6.3(b) shall not
    apply to the Federal lands and the United States reserves the right to establish higher
    8
    In 1980, when the Unit was formed, the applicable regulations required a
    supervisor of the USGS to approve unit agreements. The supervisor was required to
    make a determination that the unit was necessary or advisable in the public interest
    and was for the purpose of conserving the natural resource. See 
    30 U.S.C. § 226.8
    (1980); ROA, at 220.
    9
    Appellate Case: 21-2011     Document: 010110678144        Date Filed: 05/02/2022    Page: 10
    minimum values for Federal substances.” 
    Id.
     Therefore, the approved Unit
    Agreement required federal lessees to pay royalties on the higher of either (1) the net
    proceeds derived from the sale of CO2 gas at the well, or (2) a minimum value
    established by the United States. 
    Id.
     at 429 [§ 6.3], 465.
    2.     Hess Operations and Royalty Payments
    Hess owned approximately ten percent of the working interest in the Unit since
    it was formed. During the relevant audit period, Hess sold a small percentage of the
    CO2 it produced from the Unit under an arm’s-length contract with Fasken Oil and
    Ranch, Ltd. (“Fasken Contract”). Id. at 222. Hess had no other sales of CO2 during
    the relevant period. Id. at 224. Hess instead used the vast majority of the CO2
    allocated to its Leases for its own use in enhanced oil recovery (“EOR”) projects in
    the Permian Basin in West Texas and New Mexico. 9 Id. at 223–24. In addition to
    sourcing its own CO2 from the Unit, Hess also purchased a large volume of CO2 from
    other Unit working-interest owners to use in its EOR operations (“Hess Purchase
    Contracts”). Id.
    To transport the CO2 from the Unit to the Permian Basin EOR units, Hess first
    transported the CO2 through the Rosebud Pipeline and Sheep Mountain Pipeline to a
    9
    Enhanced oil recovery is the extraction of crude oil from an oil field that
    cannot be extracted otherwise. The process involves injecting liquified CO2 into the
    pore space of reservoir rock to help displace oil and drive it to a production wellbore.
    At the surface, the CO2 is separated from the oil, the oil is sold, and the CO2 is reused
    again in the EOR reservoir. This means that the CO2 used in EOR operations is part
    of a continual process and is not sold. See, e.g., ROA, at 223–24.
    10
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022    Page: 11
    hub in Denver City, Texas (“Denver Hub”). Id. at 221. From the Denver Hub, Hess
    transferred the CO2 into two other pipelines for delivery into the Permian Basin EOR
    units. Id. Each step of transportation required the CO2 to be at a particular pressure.
    The wellhead pressure of the CO2 in the Unit ranged from 16 to 78 pounds per square
    inch gauge (“psig”), but the pressure necessary to enter the Rosebud Pipeline was
    1,850 psig. Id. Accordingly, before the CO2 could enter the Rosebud Pipeline, Hess
    gathered the CO2 on the Unit and compressed it to 1,850 psig. Along the route to the
    Permian Basin EOR units, the pressure of the CO2 again was appropriately adjusted
    to meet the varying pressure requirements: 1,925 psig at the interconnect between the
    Rosebud Pipeline and Sheep Mountain Pipeline; 2,150 psig at the outlet of the Sheep
    Mountain Pipeline at the Denver Hub; and upwards of 2,500 psig to enter the
    Permian Basin EOR units. Id. at 221–22.
    To comply with the applicable laws, Hess was required to value its CO2
    production for royalty purposes. Because Hess transported the majority of its federal
    CO2 production to the Permian Basin EOR units (only a small percentage went to the
    Fasken Contract) and the CO2 continued to be reused in the Permian Basin EOR
    units, Hess had no other sales of CO2 to use as reference for royalty valuation. Id.
    at 224. During the audit period, Hess paid royalties based on “the Unit Average,”
    which the Unit Operator provided lessees on a monthly basis using a “netback
    approach.” Id. Under the netback approach, the Unit Operator determined the Unit
    Average by taking the price or value lessees in the Unit received for their sale of the
    CO2 at the Denver Hub. Id. The Unit Operator then deducted transportation costs
    11
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022       Page: 12
    from those values and prices to arrive at a value for the CO2 removed at the Unit. Id.
    Hess reported these prices as the basis of its royalty payments throughout the audit
    period. Id.
    Beginning in March 2004, Hess also started reporting the compression and
    dehydration costs it incurred for delivery to the Permian Basin EOR units as a
    transportation allowance. Id. Hess reported compression and dehydration costs in
    the amount of $806,290.73 during the audit period. Id. at 276.
    3.      Smithson Litigation and Arbitration Decision
    During the audit period, Hess also was a working-interest owner and operator
    in some of the EOR units in West Texas. Id. at 222. In 2006, a group of private
    lease royalty owners sued Hess in the District of New Mexico, alleging that Hess
    undervalued royalties by intentionally negotiating lower prices for the CO2 in its
    purchase contracts and then using that lower price to value its in-kind sales to
    determine the amount of royalties it owed. See Smithson v. Amerada Hess Corp.,
    No. 06-624-MCA (D.N.M. 2006).
    The matter proceeded to arbitration. A three-member arbitration panel
    determined that from October 2003 through December 2008, Hess had breached its
    duty of good faith and fair dealing to the royalty owners by obtaining the lowest
    fixed price possible for CO2 and using this “improper benchmark” to value its in-kind
    sales to them. ROA, at 351. To calculate a proper price, the panel “considered the
    numerous options of benchmarks and methodologies offered by the parties at the
    arbitration,” as well as the trove of evidence the parties provided that included
    12
    Appellate Case: 21-2011     Document: 010110678144         Date Filed: 05/02/2022      Page: 13
    contracts and relevant pricing mechanisms. Id. at 353, 356–66. The panel also
    considered the testimony of Hess’s valuation specialist, who indicated that the proper
    formula “should be reflective of the market conditions in the fall of 2003, as well as
    reflecting the historical contracting practices from the . . . pool of contracts [that the
    parties provided].” Id. at 274. The panel ultimately determined that “the ‘blend’ of
    the 2 methods suggested by [Hess’s valuation specialist] . . . [was] the proper
    benchmark for the applicable period” (“the Smithson formula”). Id.; see also id.
    at 356–66 (detailing the Smithson formula).
    Hess sought vacatur of the arbitration panel’s decision, but the parties then
    entered a settlement agreement. Id. at 263–69. In March 2010, the district court
    approved the settlement agreement. Id. at 489–94.
    4.     New Mexico Audit
    Pursuant to 
    30 U.S.C. § 1735
    , ONRR delegated authority to audit Hess’s
    royalty reports and payments for the period of January 1, 2002, to November 30,
    2010, to New Mexico’s Taxation and Revenue Department (“New Mexico”).
    On September 22, 2009, New Mexico sent Hess an initial audit issue letter
    stating that Hess owed an additional $1,458,127.94 for the period of January 2002
    through December 2005. 
    Id.
     at 292–97. The letter suggested that the third regulatory
    benchmark applied (the net-back method, 
    30 C.F.R. § 206.152
    (c)(3)) and valued
    Hess’s CO2 based on the single arm’s-length Fasken Contract. 
    Id. at 295
    .
    New Mexico then corresponded with ONRR regarding Hess’s CO2 valuation
    and allowable transportation deductions. On January 12, 2011, ONRR sent New

    Mexico a response letter. 
    Id.
     at 407–11. In the response letter, ONRR explained that
    although the Minerals Management Service had in the past directed the Unit’s
    producers to value their gas based on the Unit Average, “under different market
    scenarios and dispositions of Bravo Dome production, it does not dictate how value
    for royalty purposes must be established during later time periods.” 
    Id. at 410
    . In
    doing so, ONRR noted that the Unit Average “falls short” because CO2 values
    determined by other Unit producers, including non-federal lessees, would not
    necessarily be relevant and ONRR could not easily verify whether such valuations
    met federal requirements. 
    Id.
    ONRR went on to explain that “absent lack of significant arm’s-length sales in
    the Bravo Dome field, royalty value must be determined in the Permian Basin EOR
    units where there is an established market for CO2”—i.e., where Hess ultimately used
    the CO2. 
    Id.
     But ONRR observed that Hess purchased large quantities of CO2 for its
    own use and on behalf of other working-interest owners in its Permian Basin EOR
    operations. 
    Id.
     Hess therefore had “far more incentive to obtain the lowest possible
    price for CO2 used in its Permian Basin EOR Units than it [did] to obtain a reasonable
    value for the government’s royalty share of CO2 from the Bravo Dome Unit” and was
    arguably “able to depress the market price of CO2 in order to obtain the highest
    possible return on its Permian Basin oil production.” 
    Id.
     Consequently, ONRR
    concluded that the Smithson formula was a reasonable valuation under the second
    regulatory benchmark. 
    Id.
     (citing 
    30 C.F.R. § 206.152
    (c)(2)).
    14
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022      Page: 15
    Regarding whether Hess’s compression and dehydration costs could be
    deducted as a transportation allowance, ONRR determined that “since the Permian
    Basin [where Hess used the CO2 in EOR units] is the market for Bravo Dome CO2,
    the requirements to place CO2 into marketable condition would be established there.”
    
    Id. at 411
    . This meant that “[a]ny costs incurred to compress the CO2 up to [the
    required pressure for injection at the Permian Basin EOR units] would not be
    deductible from royalties as a transportation allowance.” 
    Id.
    On February 1, 2011, New Mexico sent Hess a revised issue letter that was
    generally consistent with ONRR’s January 12, 2011 letter. 
    Id.
     at 285–91. The
    revised letter acknowledged that although the Unit Average valuation method “may
    have been acceptable in the past under different market scenarios and dispositions of
    Bravo Dome production, it does not dictate how value for royalty purposes must be
    established during the later periods.” 
    Id. at 286
    . In Hess’s case, the lack of
    arm’s-length sales of significant volumes in the Bravo Dome field meant that
    “royalty value must be determined in the Permian Basin EOR units where there is an
    established market for CO2.” 
    Id.
     at 286–87. The revised letter further explained that
    because Hess did not dispose of the majority of its CO2 under arm’s-length contracts,
    Hess should value its production using the Smithson formula under the second
    regulatory benchmark. 
    Id.
     Regarding transportation deductions, the revised letter
    stated that “[c]ompression and dehydration costs are costs to get the CO2 gas to
    marketable condition needed for EOR production,” so Hess could not deduct the
    costs incurred to compress the CO2 up to the pressure requirement for the EOR
    15
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022    Page: 16
    delivery pipelines as a transportation allowance. 
    Id. at 288
    . The revised letter also
    expanded the audit period to run from January 1, 2002, through November 30, 2010.
    
    Id. at 285
    .
    On March 11, 2011, Hess responded to the revised issue letter and raised
    arguments regarding valuation and marketable condition. 
    Id.
     at 276–79. After
    reviewing Hess’s response, New Mexico reevaluated its proposed valuation method
    but adhered to its position that the Unit Average was an inappropriate valuation
    method and that Hess’s claimed compression and dehydration costs were not
    deductible as a transportation allowance. 
    Id.
     at 225–26.
    5.     Administrative Proceedings
    On December 19, 2011, ONRR issued an Order to Report and Pay Additional
    Royalties based on New Mexico’s audit that ordered Hess to report and pay
    additional royalties of $1,874,524.54 for the audit period of January 1, 2002, through
    November 30, 2010. 
    Id.
     at 270–82. Additionally, in its royalty reports, Hess had
    reported CO2 volumes based on a pressure base of 15.025 psia in accordance with the
    terms of the Unit Agreement. 
    Id.
     at 429 [§ 6.2]. The Order required Hess to correct
    its royalty reports to report CO2 volumes based on a pressure base of 14.73 psia in
    accordance with the 1988 regulations. See 
    30 C.F.R. § 202.152
    .
    In the Order, ONRR explained that Hess’s use of the Unit Average price to
    value its CO2 production was unacceptable because no mechanism was in place to
    verify (1) if the Unit sales price reported by all producers to the Unit Operator was in
    accordance with federal regulations; (2) how the price was derived from producers;
    16
    Appellate Case: 21-2011    Document: 010110678144         Date Filed: 05/02/2022    Page: 17
    (3) if producers reduced their reported Unit prices, as provided to the Unit Operator,
    by the cost of placing the CO2 production into marketable condition; (4) if calculated
    transportation costs were in accordance with federal regulations; or (5) if all federal
    lessees were using the Unit Average price when paying royalties. 
    Id. at 272
    . Put
    simply, ONRR rejected Hess’s supplied Unit Average valuation because it included
    unverified arm’s-length and non-arm’s-length sales.
    ONRR then outlined how Hess was required to value its CO2 production for
    royalty purposes. The majority of the CO2 that Hess produced (more than 99%) was
    transported for use in the Permian Basin EOR units, and while Hess sold a de
    minimus volume of CO2 under the single arm’s-length Fasken Contract, “the gross
    proceeds were not equivalent to the gross proceeds derived from, or paid under,
    comparable arm’s-length contracts.” 
    Id. at 271
    . Taking this into consideration along
    with the variability of pricing mechanisms present in the Hess Purchase Contracts,
    ONRR directed the use of the following valuations for the audit period:
    • January 2002–September 2003 & April 2008–November 2010: The
    best representation of value for these periods was a “weighted average,”
    which included only Hess’s verified purchases of CO2 in the Permian
    Basin as well as the Fasken Contract.
    • October 2003–March 2008: The best representation of value for this
    period was the Smithson formula because this formula was based on
    transparent, reliable, and relevant evidence including expert testimony
    17
    Appellate Case: 21-2011    Document: 010110678144       Date Filed: 05/02/2022   Page: 18
    from Hess’s valuation specialist and CO2 purchase contracts, pricing
    mechanisms, and historical contracting practices from this time. 10
    
    Id.
     at 273–74.
    ONRR further agreed with New Mexico’s conclusion that Hess could not
    deduct its compression and dehydration costs as a transportation allowance. 
    Id.
    at 275–76. ONRR observed that the pressure required for CO2 delivery along the
    pipelines to the Permian Basin did not exceed the pressure requirements for use in the
    Permian Basin EOR units, plus typical sales or purchases contracts for the Unit’s
    CO2 production also contained these pressure requirements as a condition for use in
    the Permian Basin EOR units. 
    Id. at 275
    . The costs of compression and dehydration
    up to the EOR requirements, ONRR reasoned, therefore were costs of placing the
    CO2 into marketable condition. 
    Id.
     ONRR noted that substantial case law supported
    its position to disallow the costs of compression and dehydration necessary to meet
    pressure requirements for CO2 delivery to EOR operations.

    10
    OXY asserts that ONRR “ordered Hess to use three different values for the
    same CO2 during the Audit Period,” but the record shows that the agency directed the
    use of only two values: the “weighted average” and the Smithson formula. Compare
    Aplt. Br. at 12 with ROA, 273–74.
    18
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022    Page: 19
    On September 13, 2016, ONRR’s Director issued a decision, which largely
    affirmed the agency’s Order to Report and Pay Additional Royalties. 
    Id.
     at 217–54.
    The Director determined that ONRR reasonably established a minimum value for
    Hess to use to calculate the value of its federal CO2 production based on Hess’s gross
    proceeds under the Fasken Contract, the price that Hess purchased CO2 from other
    lessees, and the Smithson formula. In reaching this conclusion, the Director found
    that ONRR never had required Hess to only use the Unit Average valuation and that
    the terms of the Unit Agreement and underlying Leases actually allowed ONRR,
    independent of the 1988 regulations, to establish a reasonable value for Hess’s CO2
    within the bounds of the Lease valuation factors. 
    Id.
     at 227–28, 248–53. But the
    Director also analyzed ONRR’s valuation under the applicable 1988 regulations,
    specifically the second regulatory benchmark, and determined that the result would
    be the same. 
    Id.
     at 239–43. The Director then determined that ONRR properly
    denied Hess’s claimed compression and dehydration costs as a transportation
    allowance because these costs were necessary to place the CO2 in marketable
    condition. 
    Id.
     at 243–47.
    Lastly, regarding the pressure base calculation, the Director realized that the
    regulations and Unit Agreement were in conflict on this point. 
    Id.
     at 247–48. In
    1980, when USGS approved the Unit Agreement, the regulations required lessees to
    base royalty payments on “10 ounces above an atmospheric pressure of 14.4 pounds
    to the square inch, regardless of the atmospheric pressure at the point of
    measurement.” 
    Id.
     (citing 
    30 C.F.R. § 221.44
     (1980)). The regulations required
    19
    Appellate Case: 21-2011    Document: 010110678144       Date Filed: 05/02/2022       Page: 20
    lessees to adjust their royalty computation to those standards “unless otherwise
    authorized in writing by the supervisor.” 
    Id.
     Because USGS approved the Unit
    Agreement in writing and the Unit Agreement required Hess to remit royalties on
    CO2 volumes at a pressure base on 15.025 psia, the Director determined that Hess
    needed to report and pay royalties on volumes at the 15.025 psia pressure base. 
    Id.
    The Director applied the correct pressure base and reduced the royalty amount due
    accordingly. 11 
    Id.
    Hess appealed to the Interior Board of Land Appeals, which exercises the
    Secretary of the Interior’s de novo review authority for subordinate agency decisions.
    
    Id. at 330
    . The Board did not issue a final merits decision prior to the 33-month
    limitations period. See 
    30 U.S.C. § 1724
    (h)(1); ROA, at 321–23. The Director’s
    decision thus became the agency’s final decision ripe for judicial review. 
    30 U.S.C. § 1724
    (h)(2)(B); 
    43 C.F.R. § 4.906
    (a).
    6.     District Court Opinion
    OXY then brought this lawsuit, challenging the decision of ONRR’s Director
    under the Administrative Procedure Act (“APA”), 
    5 U.S.C. § 706
    (2)(A). ROA,
    at 19–22. Applying the appropriate deferential standard of review, the district court
    affirmed the Director’s decision. 
    Id.
     at 70–93. The district court first acknowledged
    11
    The Director reduced the amount due from $1,874,524.54 to $1,820,652.66
    (a difference of $53,891.88), which reflects the amount due as a result of previously
    requiring Hess to report its CO2 volumes on a 14.73 psia pressure base. ROA,
    at 247–48, 253. OXY does not challenge the Director’s calculation of the pressure
    base or that the Unit Agreement is controlling in this aspect.
    20
    Appellate Case: 21-2011      Document: 010110678144      Date Filed: 05/02/2022      Page: 21
    the Director’s conclusion that ONRR’s valuation was to be assessed under the Lease
    valuation factors, and it observed that ONRR had considered the relevant factors and
    evidence in establishing a reasonable minimum value and had thoroughly explained
    its decision. 
    Id.
     at 78–84. ONRR also had “appropriately considered and rejected
    the Unit Average,” as the Director’s decision “extensively explained why the Unit
    Average was not satisfactory and why [the agency] was using a new valuation
    method.” 
    Id.
     at 84–85.
    The district court then considered the Director’s alternative conclusion that
    ONRR’s valuation also was reasonable under the second regulatory benchmark. 
    Id. at 87
    . Because the Director had analyzed the relevant facts and articulated what
    evidence he considered under each regulatory valuation factor, the district court
    determined that it “[would] not second-guess the Director’s decision in weighing the
    regulatory factors.” 
    Id.
    Finally, regarding whether compression and dehydration costs were deductible
    as a transportation allowance, the district court concluded that the Director’s decision
    “cogently explain[ed] that the costs are not deductible because they are necessary to
    place the carbon dioxide in marketable condition.” 
    Id. at 88
    . In particular, the
    Director’s interpretation and application of the marketable-condition rule to OXY’s
    case was “not plainly erroneous or inconsistent with the regulation.” 
    Id. at 91
    .
    OXY now appeals to this court.

    abuse of discretion, or otherwise not in accordance with law.”

    An agency’s decision is arbitrary and capricious if the agency (1) “entirely failed to
    consider an important aspect of the problem,” (2) “offered an explanation for its
    decision that runs counter to the evidence before the agency, or is so implausible that
    it could not be ascribed to a difference in view or the product of agency expertise,”
    (3) “failed to base its decision on consideration of the relevant factors,” or (4) made

    III
    OXY argues on appeal that ONRR’s decision is arbitrary, unsubstantiated, and
    internally inconsistent and the district court erred in affirming the agency’s decision.
    OXY asserts that ONRR’s Director incorrectly found the agency’s valuation
    reasonable under the Lease valuation factors, improperly rejected Hess’s Unit
    Average as the valuation method, and misapplied the 1988 regulatory factors to
    alternatively affirm the agency’s valuation under the second regulatory benchmark.
    OXY further asserts that the Director erred in determining that Hess’s compression
    and dehydration costs are not deductible as a transportation allowance.
    23
    Appellate Case: 21-2011     Document: 010110678144        Date Filed: 05/02/2022    Page: 24
    We conclude that ONRR’s valuation is not arbitrary or capricious, is supported
    by substantial evidence, and is otherwise in accordance with law, and we affirm the
    Director’s decision. We will address each of OXY’s contentions in turn.
    A.    ONRR’s Valuation
    We first will consider whether the Director erred in determining that ONRR
    reasonably established a minimum value for Hess to use to calculate the value of its
    federal CO2 production. ONRR’s valuation used (1) the “weighted average” from
    January 2002 to September 2003 and April 2008 to November 2010, and (2) the
    Smithson formula from October 2003 to March 2008. ROA, at 273–74.
    At the outset of the Director’s decision, the Director noted that the approved
    Unit Agreement, along with the underlying Leases, required the federal lessees to pay
    royalties on the higher of either (1) the net proceeds derived from the sale of CO2 gas
    at the well, or (2) a minimum value established by the United States. 
    Id.
     at 429
    [§ 6.3], 465. Recall that if the applicable 1988 regulation is inconsistent with a lease,
    then the lease governs to the extent of that inconsistency. 
    30 C.F.R. § 206.150
    (b).
    The 1988 regulations authorize a lessee to first compute the minimum royalty value
    through the benchmark system, and ONRR is then empowered to determine whether
    the lessee’s valuation is inconsistent with the applicable regulations.
    §§ 206.152(c)(1)–(3), 206.152(e)(1). In contrast, under the Unit Agreement and
    underlying Leases, the Secretary retains the right to establish the royalty value on
    CO2 production based on the Lease valuation factors following notice and an
    opportunity to be heard when appropriate. After comparing the regulations and the
    24
    Appellate Case: 21-2011    Document: 010110678144       Date Filed: 05/02/2022      Page: 25
    Unit Agreement, the Director determined that “[t]he Leases and Unit Agreement
    govern the value of Hess’s CO2 for federal royalty purposes” because “the Secretary
    retained the right to establish a minimum value for federal CO2 production in the
    Unit in its approval of the Unit Agreement.” ROA, at 227–28, 239.
    Because Hess did not sell the CO2 production at issue, the Director evaluated
    ONRR’s valuation under the Lease valuation factors to see if ONRR had properly
    established a reasonable minimum value, after giving Hess notice and an opportunity
    to be heard:
    (1) The Highest Price Paid for a Part or for a Majority of Production of
    Like Quality in the Same Field: The Director explained that federal
    lessees in the Unit (holding less than ten percent of an interest in the
    Unit) sell less than one percent of the CO2 produced from the federal
    lands. Federal lessees use the remainder in their EOR operations.
    ONRR only had data for the federal CO2 production and considered that
    data set, but the agency reasonably concluded that the data set was too
    small to accurately establish a minimum value. ONRR also could not
    consider the Hess Purchase Contracts under the first factor because the
    agency could not determine whether such contracts represented the
    “highest price paid” for a part or majority of production from the Unit.
    The Director concluded that ONRR had properly considered this factor.
    (2) The Price Hess Received for the CO2: ONRR considered the Fasken
    Contract in the context of the “weighted average” calculation, but
    because this represented a very small fraction of Hess’s federal CO2
    disposition, ONRR determined that it could not solely rely on these
    prices alone. The Director concluded that ONRR had properly
    considered this factor.
    (3) Posted Prices: ONRR could not consider posted prices for CO2
    production because no posted prices for CO2 in the Unit existed during
    the audit period. The Director concluded that ONRR had properly
    considered this factor.
    (4) Other Relevant Matters: ONRR considered the Unit Average, the
    prices at which Hess purchased CO2 under the Hess Purchase Contracts,
    25
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022     Page: 26
    and pricing mechanisms used in Hess’s settlements and arbitrations,
    including the Smithson formula. The Director found that these
    considerations were reasonable, as they helped ONRR identify reliable
    indicators of value. The Director concluded that ONRR had properly
    considered this factor.
    Id. at 227–39; see also id. at 442b, 446b, 450b, 454b [Sec. 2(d)(2)]. The Director
    concluded overall that there was insufficient information as to the first and third
    factors, so ONRR’s reliance on the second and fourth factors to establish its valuation
    was reasonable.
    In determining that ONRR’s valuation was reasonable, the Director explained
    why ONRR’s consideration of the Smithson arbitration was proper: (1) the arbitration
    panel found that Hess had negotiated lower fixed prices for its CO2 purchases and
    then had used those lower prices to value the CO2 for royalty purposes; (2) Hess “had
    the full opportunity to challenge and offer alternatives to the method the arbitration
    panel used to calculate value and damages”; and (3) the arbitration panel “used a
    formula price that took into account Hess’s argument for a flat price,” as well as the
    suggestions of Hess’s valuation specialist. Id. at 236–37.
    The Director also explained why Hess’s Unit Average could not be used to
    determine the value of Hess’s CO2 production: (1) it was “extremely difficult to
    verify the prices under the Unit Average are consistent with federal valuation
    requirements”; (2) the Unit Average “results in a value that is less than the price Hess
    is willing to pay for CO2”; and (3) the Unit Average likely included prices from
    non-arm’s-length CO2 sales. Id. at 234–36, 253. The Director observed that ONRR
    and New Mexico had provided Hess ample notice through correspondence that the
    26
    Appellate Case: 21-2011    Document: 010110678144       Date Filed: 05/02/2022     Page: 27
    agency was considering a different valuation method than the Unit Average. New
    Mexico sent Hess two audit letters indicating that the Unit Average was not an
    appropriate basis for Hess to use to value its federal CO2 production, to which Hess
    responded. Id. at 238.
    The Director further concluded that ONRR never had demanded that Hess use
    the Unit Average valuation in perpetuity, as Hess seemed to claim. Id. at 248–53.
    Hess argued that ONRR consistently had required Hess to use the Unit Average to
    value its CO2 and that the Unit Average originated from an Amoco proposal to
    ONRR on how Amoco should value its federal CO2 production from the Unit. Id.
    at 248. The Director examined the sources on which Hess relied and explained in
    detail that they did not amount to the agency’s endorsement of the Unit Average, but
    to the extent they did, any such guidance was based on the facts presented at the time
    and did not bind the agency to the Unit Average methodology decades later. Id.
    at 248–53.
    After analyzing the reasonableness of ONRR’s valuation under the Lease
    valuation factors and rejecting the Unit Average, the Director determined that “the
    result would be the same even if the federal gas royalty valuation regulations
    controlled the outcome of this case.” Id. at 239 (citing 
    30 C.F.R. § 206.152
    (c)(2)).
    The Director considered ONRR’s valuation under each of the second benchmark
    regulatory factors:
    (1) The Gross Proceeds Under Arm’s-Length Contracts for Like-Quality
    Gas in the Same Field or Nearby Fields or Areas: ONRR considered
    the gross proceeds under arm’s-length contracts for like quality gas,
    27
    Appellate Case: 21-2011    Document: 010110678144       Date Filed: 05/02/2022      Page: 28
    including the arm’s-length Fasken Contract. The Fasken Contract was
    the only contract in the record that ONRR could verify as an
    arm’s-length contract. The Director concluded that ONRR had properly
    considered this factor.
    (2) Posted Prices: ONRR observed that the record did not include any
    evidence of posted prices, so the agency could not evaluate this factor.
    The Director concluded that ONRR had properly considered this factor.
    (3) Prices Received in Arm’s-Length Spot Sales: ONRR observed that the
    record did not include any evidence of prices received in arm’s-length
    spot sales, so the agency could not evaluate this factor. The Director
    concluded that ONRR had properly considered this factor.
    (4) Other Reliable Public Sources of Price or Market Information:
    ONRR considered the Smithson formula and Hess’s other settlements as
    a means to determine value, but as discussed, it determined that the
    Smithson formula was a more appropriate and reliable indicator of value
    for the period of October 2003 through December 2008. The Director
    concluded that ONRR had properly considered this factor.
    (5) Other Information Particular to a Lease Operation or Saleability of
    the Gas: Here ONRR considered the Hess Purchase Contracts and the
    Unit Average that Hess had used as the basis for its royalty payments.
    ONRR ultimately concluded that the Hess Purchase Contracts were a
    more appropriate indicator of value than the Unit Average and used the
    Hess Purchase Contracts as part of its final “weighted average”
    valuation. The Director concluded that ONRR had properly considered
    this factor.
    
    Id.
     at 242–43. The Director concluded overall that ONRR had considered every
    potential indicator of value in the record under the second regulatory benchmark.
    On appeal, OXY raises three issues regarding ONRR’s valuation: (1) the
    Director incorrectly concluded that ONRR’s valuation was reasonable under the
    Lease valuation factors; (2) the Director improperly rejected Hess’s Unit Average as
    the valuation method; and (3) the Director misapplied the 1988 regulatory factors to
    alternatively affirm the agency’s valuation under the second regulatory benchmark.
    28
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022    Page: 29
    1.     Reasonableness of ONRR’s Valuation
    OXY first argues that ONRR’s valuation is unreasonable and arbitrary. While
    OXY does not provide any meaningful challenge to ONRR’s consideration of the
    Fasken Contract or the Hess Purchase Contracts, OXY repeatedly asserts that
    ONRR’s consideration of the Smithson formula was inappropriate because the
    arbitration decision did not involve federal leases and only resolved a royalty dispute
    between Hess and private lease owners. Aplt. Br. at 11–12, 45–47. In making this
    argument, OXY contends that the Smithson formula never had been used to buy or
    sell any CO2; the Smithson formula was not legally binding because the parties
    settled after arbitration and the Smithson formula was not agreed to in the settlement;
    arbitration awards and decisions have no precedential effect in other cases; and the
    Smithson formula does not qualify as relevant evidence under the Lease valuation
    factors or the 1988 regulatory factors. 
    Id.
     at 46–49. Relatedly, OXY argues that if
    the agency rejected the Unit Average due to the inclusion of non-arm’s-length
    transactions, then it should not have considered the Smithson formula because it
    included non-arm’s-length transactions. 12 
    Id. at 43, 49
    .
    12
    OXY also argues that ONRR’s valuation is arbitrary and inconsistent
    because “[t]he history of this matter involves no less than four administrative
    decisions differently valuing [Hess’s] Audit Period CO2 production.” Aplt. Br. at 19
    (emphasis in original). OXY characterizes this history as “a vacillating scattershot of
    substitute methodologies to re-value [Hess’s CO2 production].” 
    Id.
     In actuality,
    OXY is referencing the aforementioned correspondence that occurred among New
    Mexico, ONRR, and Hess during the audit process, and as discussed, the record
    shows that ONRR only issued one Order to Report and Pay Additional Royalties on
    29
    Appellate Case: 21-2011    Document: 010110678144       Date Filed: 05/02/2022     Page: 30
    We conclude that the Director considered all relevant evidence and provided
    sufficient reasoning for each of ONRR’s determinations regarding the valuation.
    Under the deferential APA standard, we ask whether the agency’s decision was based
    on an examination of the relevant evidence and if the agency “articulated a rational
    connection between the facts found and the decision made.” Payton, 
    337 F.3d at 1168
    . The Director’s methodology and detailed explanations certainly pass muster
    under the APA’s deferential framework. The agency considered all relevant
    information that was reasonably available, including the single arm’s-length Fasken
    Contract, the Hess Purchase Contracts, and the Smithson formula for production
    occurring between October 2003 and March 2008. ROA, at 233–37. The Director
    then articulated a rational connection between the relevant information and ONRR’s
    valuation under the Lease valuation factors and weighed the factors accordingly. 
    Id.
    The Director then analyzed the second regulatory benchmark factors at length and
    explained why the result would be the same if the regulatory valuation factors
    applied. Echoing the district court, we cannot reweigh the evidence, which seems to
    be what OXY is requesting.
    As to the Smithson formula, the agency was clear that consideration of this
    formula was appropriate because the question under both Hess’s Leases and the 1988
    regulations—the reasonable value of Hess’s CO2 based on all relevant and reliable
    December 19, 2011, which ONRR’s Director then reduced in OXY’s favor on
    review. See ROA, at 217–54, 270–82.
    30
    Appellate Case: 21-2011       Document: 010110678144      Date Filed: 05/02/2022     Page: 31
    information—was fundamentally the same inquiry that the Smithson arbitration panel
    conducted. During the audit, the agency discovered that Hess did not have other
    reliable public sources of price or market information for the audit period, except for
    the negligible Fasken Contract. The agency realized that the Smithson formula
    provided an appropriate and reliable indicator of value from October 2003 through
    December 2008 and therefore considered the formula in its analysis of “other
    relevant matters” under the Lease valuation factors, as well as under “other reliable
    public sources of price or market information” in its alternative analysis of the 1988
    regulatory factors. 
    Id.
     at 227–39, 242–43. As the Director explained, the formula
    was the result of a neutral arbitration panel with full transparency into the basis for
    the formula price, whereas Hess’s other settlement agreements did not “provide any
    information on what was at issue, how the parties came to the formula price, or how
    that price pertains to Hess’s CO2 purchases or sales.” Id. at 236. Moreover, the
    arbitration panel set the formula price by blending two valuation methodologies
    based on expert testimony proffered by each of the parties, and the formula reflected
    “market conditions in the fall of 2003, [and] historical contracting practices.” Id.
    at 230–37. It was proper for the agency to rely on the Smithson formula, not for its
    precedential value, but rather for the relevant and reliable information it provided
    about Hess’s CO2 purchase contracts, pricing mechanisms, and historical contracting
    practices from this time.
    OXY also contends that the Director’s decision to consider ONRR’s valuation
    under the Lease valuation factors, instead of only the 1988 regulatory factors,
    31
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022    Page: 32
    warrants reversal because this court’s affirmance “would inject substantial
    uncertainty to royalty valuation for thousands of similarly-situated federal oil and gas
    [standard-form] leases” and the 1988 regulations “cabin ONRR’s ability to substitute
    its own royalty value.” Aplt. Br. at 21–31; Aplt. Reply Br. at 4–5. But the Director’s
    decision was clear that it analyzed ONRR’s valuation in OXY’s case under the Lease
    valuation factors because the specific Bravo Dome Unit Agreement controlled: The
    Secretary “retained the right to establish a minimum value for federal CO2 production
    in the Unit in its approval of the [Bravo Dome] Unit Agreement,” which modified
    Hess’s underlying standard-form Leases to the extent they were inconsistent with the
    Unit Agreement. ROA, at 227–28, 424. The Director applied this same logic to
    reduce the pressure base calculation in accordance with the Unit Agreement in
    OXY’s favor, which OXY does not dispute. Id. at 247–48. Further, any such
    procedural inconsistency authorizing the Secretary to determine royalty valuation in
    the first instance in OXY’s case ultimately is irrelevant because (1) the Director
    reasonably articulated why the Unit Average is unreliable and (2) the Director
    independently analyzed ONRR’s valuation under the second regulatory benchmark in
    the alternative and came to the same conclusion. The Director also noted that while
    the Order had not explicitly mentioned the Lease valuation factors in its analysis of
    the second regulatory benchmark, the valuation factors overlapped, so the agency had
    thoroughly considered the Lease valuation factors in the process of analyzing the
    second regulatory benchmark. Id. at 228–38.
    32
    Appellate Case: 21-2011    Document: 010110678144        Date Filed: 05/02/2022     Page: 33
    Because the Director weighed the relevant factors and evidence and adequately
    explained the agency’s decision, ONRR’s valuation is not arbitrary or capricious.
    2.     Unit Average Valuation
    OXY next argues that the Director improperly rejected Hess’s Unit Average as
    the valuation method. OXY asserts that ONRR previously had approved the Unit
    Average, and while ONRR is not estopped from conducting audits or reexamining a
    valuation methodology, the Director’s decision and administrative record do not
    clearly support a reversal of the Unit Average. ONRR merely substituted its own
    methodology for the Unit Average “to extract more royalty dollars” without actually
    finding that the Unit Average was inconsistent with the regulations. Aplt. Br. at 17.
    OXY contends that ONRR instead should have conducted additional investigation
    into the pricing practices of other Unit entities before rejecting the Unit Average. Id.
    at 36–46.
    We conclude that the Director’s decision to reject the Unit Average valuation
    methodology is not arbitrary or capricious. In order for this court to reverse ONRR’s
    decision, we would have to conclude that the agency failed to consider an important
    aspect of the problem, offered an explanation for its decision that runs counter to the
    evidence before the agency, or failed to base its decision on consideration of the
    relevant factors. Utah Env’t Cong., 
    479 F.3d at 1280
    . The record presented does not
    support our reaching any of these conclusions in this case. ONRR provided a
    reasoned basis for rejecting the Unit Average price methodology under the applicable
    regulations. ROA, at 234–36. ONRR’s justifications collectively reinforce each
    33
    Appellate Case: 21-2011    Document: 010110678144       Date Filed: 05/02/2022     Page: 34
    other: It was reasonable for ONRR to determine that the Unit Average—comprised
    primarily of non-federal lessees that are not subject to ONRR’s regulations or
    oversight mechanisms, that ONRR cannot audit, and that use valuation
    methodologies both largely unknown to ONRR and likely based at least in part on
    non-arm’s-length sales—was not an appropriate measure of value, particularly since
    the Unit Average resulted in a price lower than the Hess Purchase Contracts that
    ONRR was able to examine.
    The Director also explained in detail why any previous guidance or orders
    Hess received (namely 1980s-era correspondence between Amoco and the Minerals
    Management Service) that supported Hess using the Unit Average to calculate its
    royalties on its federal CO2 production were not germane. 
    Id.
     at 248–53. As ONRR
    points out, none of the guidance OXY invokes had the force of law or was otherwise
    binding on the agency. Aple. Br. at 31–37. And even if OXY was correct that
    ONRR’s rejection of the Unit Average here conflicts with prior agency policy,
    nothing prevented ONRR from changing its position so long as it provided a
    reasonable explanation for doing so—and ONRR plainly provided a reasonable
    explanation for rejecting the Unit Average.
    The agency’s decision to reject the Unit Average is supported by substantial
    evidence and is not arbitrary or capricious.
    3.     Second Regulatory Benchmark
    OXY then argues that the Director misapplied the 1988 regulatory factors to
    alternatively affirm the agency’s valuation under the second regulatory benchmark.
    34
    Appellate Case: 21-2011     Document: 010110678144        Date Filed: 05/02/2022        Page: 35
    Here, OXY’s challenge focuses on the district court’s analysis, rather than
    maintaining the required focus on the Director’s analysis under the APA. Aplt. Br.
    at 32–36. In affirming the Director’s alternative analysis under the 1988 regulatory
    factors, the district court stated that it “[would] not second-guess the Director’s
    decision in weighing the regulatory factors where the Director considered and
    analyzed the relevant factors and evidence.” ROA, at 87 (emphasis added). OXY
    takes issue with this statement because the district court “overlook[ed] the threshold
    point that the Director had no occasion to second-guess Hess’[s] valuation in the first
    instance.” Aplt. Br. at 35.
    OXY’s assertion is plainly wrong under the 1988 regulations, as well as the
    Unit Agreement and underlying Leases. Under the 1988 regulations, ONRR is
    required to audit the valuations that lessees supply and provide reasons for rejecting a
    lessee’s application of the regulatory benchmarks. 
    30 U.S.C. § 1711
    (c). Under the
    Unit Agreement and Leases, their terms dictate that ONRR retains the authority to
    establish a reasonable minimum valuation in accordance with the Lease valuation
    factors. ROA, at 442b, 446b, 450b, 454b [Sec. 2(d)(2)]. As demonstrated, ONRR
    did that here. 
    Id.
     at 242–43. Moreover, we use ordinary APA deference principles to
    review the Director’s reasons for rejecting Hess’s Unit Average and approving
    ONRR’s valuation under the second regulatory benchmark. We cannot reweigh the
    regulatory factors if substantial evidence supports the Director’s reasoning—we
    cannot even displace ONRR’s choice “between two fairly conflicting views, even
    though the court would justifiably have made a different choice had the matter been
    35
    Appellate Case: 21-2011      Document: 010110678144         Date Filed: 05/02/2022     Page: 36
    before it de novo.” Wyo. Farm Bureau Fed’n, 
    199 F.3d at 1231
     (internal citations
    omitted).
    Because the record reveals substantial evidence in support of the Director’s
    analysis of the regulatory valuation factors, the Director’s decision to alternatively
    affirm the agency’s valuation under the second regulatory benchmark is not arbitrary
    or capricious.
    B.     Transportation Costs
    The final issue OXY raises is whether the Director correctly determined that
    Hess’s compression and dehydration costs are not deductible as a transportation
    allowance because they were necessary to place Hess’s CO2 in marketable condition and
    not just transport the CO2. 13 ONRR regulations allow a lessee to deduct some, but not
    all, of the costs of transporting the gas from the lease to a downstream location.
    
    30 C.F.R. § 206.156
    (a). Under ONRR regulations and the relevant case law, a reasonable
    minimum value will not include any costs that a lessee must incur to place gas in
    marketable condition. See § 206.152(i); see, e.g., Devon Energy Corp., 
    551 F.3d at
    1036–40; Amoco Prod. Co., 410 F.3d at 729–31; Amerada Hess Corp. v. Dep’t of the
    Interior, 
    170 F.3d 1032
    , 1036–37 (10th Cir. 1999); Mesa Operating Ltd P’ship v. Dep’t
    13
    We note that while the Order appears to deduct “some transportation costs”
    from both the “weighted average” and the Smithson formula price, the Order
    explicitly disallows Hess’s reported costs associated with compression and
    dehydration that are at issue here. ROA, at 253. OXY only challenges the agency’s
    denial of these compression and dehydration costs as a transportation allowance and
    does not discuss or challenge any other transportation costs that the Order deducted
    from its valuation.
    36
    Appellate Case: 21-2011      Document: 010110678144         Date Filed: 05/02/2022        Page: 37
    of the Interior, 
    931 F.2d 318
    , 323–27 (5th Cir. 1991). Hess, as lessee, was responsible
    for the costs to gather, compress, dehydrate, and remove any impurities from the CO2 to
    meet marketable condition requirements. However, the regulations allow a lessee to
    include “[s]upplemental costs for compression, dehydration, and treatment of gas . . .
    only if such services [1] are required for transportation and [2] exceed the services
    necessary to place production into marketable condition.” § 206.157(f)(9) (emphasis
    added). So if Hess’s compression and dehydration costs (1) were required for
    transportation and (2) exceeded what was necessary to compress and dehydrate the CO2
    to place it in marketable condition, Hess could claim those costs as a transportation
    allowance.
    As the Director discussed, marketable condition means “lease products which are
    sufficiently free from impurities and otherwise in a condition that they will be accepted
    by a purchaser under a sales contract typical for the field or area.” § 206.151. The
    Director noted that “treating gas to put it in marketable condition includes gathering
    (transporting gas from individual wells to a central accumulation point . . . on or near the
    lease or unit), compression (increasing the pressure of gas), dehydration (removing
    water), and sweetening (removing acid gases, such [sic] CO2 and hydrogen sulfide
    (H2S)).” ROA, at 244–45 (citing relevant case law). In the context of Hess’s CO2
    production, the Director interpreted this marketable-condition rule as requiring Hess to
    treat its CO2 to conform with the pipeline requirements that served the markets into
    which the CO2 was sold—the Permian Basin EOR units. Id. To meet the pressure and
    quality requirements of the Permian Basin EOR units, treatment included compressing
    37
    Appellate Case: 21-2011      Document: 010110678144           Date Filed: 05/02/2022      Page: 38
    and dehydrating the CO2 to meet specifications regarding water vapor, hydrogen sulfide,
    sulfur, oxygen, nitrogen, and hydrocarbons. Id. at 245–46 (citing the terms of the Hess
    Purchase Contracts). The Director determined that “[b]ecause the ultimate use of Hess’s
    CO2 production is to inject the CO2 into the EOR facility, the EOR Delivery Pipelines
    represent the pressure and quality requirements for Hess’s CO2 to be in marketable
    condition.” Id. at 246. Accordingly, ONRR correctly concluded that Hess could not
    deduct the costs it incurred to get the CO2 to the pressure and purity specifications
    required to enter the EOR delivery pipelines. Id.
    The Director also acknowledged Hess’s argument that the compression costs were
    necessary for transport as well but explained that “even though the compressors operate
    to put the CO2 in a super critical state for transportation, they also operate to place the
    CO2 in marketable condition.” Id. The Director noted that such dual-purpose costs are
    deductible “only if such services are required for transportation and exceed the services
    necessary to place production into marketable condition,” which Hess did not establish.
    Id. at 246–47 (citing § 206.157(f)(9)) (quotations omitted).
    OXY responds that CO2 is “different from other produced federal gas” and has a
    “unique nature,” so “[c]ertain dehydration and compression costs are essential for CO2
    transportation from the [Unit] Leases to its destination in West Texas, and therefore are
    properly deductible.” Aplt. Br. at 49; Aplt. Reply Br. at 18–19. OXY contends that the
    real issue is “whether transportation is the primary, not the only, reason for dehydrating
    and compressing [its CO2].” Aplt. Br. at 49.
    38
    Appellate Case: 21-2011      Document: 010110678144         Date Filed: 05/02/2022     Page: 39
    But the Director already addressed and rejected OXY’s transportation arguments
    based on the applicable regulations and case law and in the process explained why the
    regulations do not embrace such a distinction. 14 ROA, at 243–47. We may reject the
    Director’s interpretation and application of the marketable-condition rule to this case only
    when the interpretation is “unreasonable, plainly erroneous, or inconsistent with the
    regulation’s plain meaning.” Biodiversity Conservation All., 762 F.3d at 1060. The
    regulations dictate that “costs for compression, dehydration, and treatment of gas” may
    be deducted only to the extent “such services [1] are required for transportation and
    [2] exceed the services necessary to place production into marketable condition.”
    § 206.157(f)(9). Contrary to OXY’s claims, Hess’s compression and dehydration costs
    are not “unique costs related to transportation.” Aplt. Br. at 50. For CO2 to be
    compatible with EOR operations, operators must remove impurities from the CO2 and
    increase the gas’s pressure to transform it into a critical phase—essentially, the increased
    pressure liquefies the CO2 so it can be injected at the EOR units. ROA, at 223–24. These
    compression and dehydration costs are essential to bringing Hess’s CO2 to market for its
    ultimate use in the EOR operations, even if they serve the dual purpose of helping
    transport the gas.
    14
    The sources OXY cites similarly do not support its “primary purpose” theory.
    Aplt. Br. at 49–53 (citing Shell Offshore Inc., 142 IBLA 71, 74 (1997) (allowing the
    enlargement of a floating drilling platform to buoy a compressor and other gas
    transportation equipment to be a transportation allowance under § 206.157) and Exxon
    Corp., 118 IBLA 221, 240–41 (1991) (allowing dehydration of gas streams to be a
    transportation allowance under § 206.157 because the dehydration in this instance
    “serve[d] only one purpose: transportation”)).

    Furthermore, OXY never has demonstrated or even contended that the costs to
    transport Hess’s CO2 exceeded the costs necessary to meet the minimum pressure
    requirements for the EOR delivery pipelines, let alone attempted to quantify the amount
    of any excess costs. And a review of the record reveals that the ultimate compression
    required for transport along the pipelines to the EOR units was less than the compression
    required to enter the EOR facilities. 15 As a result, OXY has not shown that the
    transportation costs “exceed[ed] the services necessary to place production into
    marketable condition.” § 206.157(f)(9).
    OXY also asserts that the record shows ONRR allowed Hess to deduct these
    compression and dehydration costs as transportation costs in the past, citing a 2002
    guidance letter from ONRR. ROA, at 412–14. But as ONRR points out, this letter does
    not support OXY’s claim that compression costs are deductible whenever they are
    “primarily required to place the CO2 into single phase to enter a large pipeline for long
    distance transport to a delivery point remote from the lease (in West Texas).” Aplt. Br.
    at 52. Rather, the letter explains that a deduction is permitted only if “this compression is
    solely to keep the CO2 in single-phase flow for transportation through a large diameter
    pipeline to a sales point remote from the lease.” ROA, at 413 (emphasis added). And
    “[i]f compression is performed to place the CO2 in marketable condition,” as OXY does
    15
    As OXY discusses in its briefing, Hess had to compress the CO2 to upwards of
    2,500 psig to enter the EOR facilities and therefore be in marketable condition. Aplt. Br.
    at 9. But Hess only had to compress the CO2 to a maximum of 2,150 psig to transport the
    CO2 to the EOR facilities along the pipelines. Id.; see also ROA, at 221–22.

    not dispute is the case here, ONRR “will not allow any deductions for compression.” 16
    Id.
    The Director’s interpretation and application of the marketable-condition rule to
    this case is not plainly erroneous or inconsistent with the applicable regulations.
    IV
    For the foregoing reasons, we AFFIRM.
    16
    OXY also argues in passing that the Director erred by relying on the regulations
    to deny transportation cost deductions because the Director had valued the CO2 under the
    Lease valuation factors. Aplt. Br. at 14, 16–17. However, as the district court observed,
    the Director’s approach is consistent with the regulations. The regulations provide that
    they should apply to the extent they are not inconsistent with the terms of the underlying
    lease. 
    30 C.F.R. § 206.150
    (b). Because OXY has not pointed to any term of the Unit
    Agreement or Leases inconsistent with the regulation’s marketable-condition rule, the
    Director appropriately applied the regulations.
