    AGEE, Circuit Judge:
    Until 2011, Ergon-West Virginia, Inc. enjoyed an exemption as a small refinery
    from the Environmental Protection Agency’s renewable fuel standard program, which
    requires refineries and other facilities to allocate a certain percentage of their fuel
    production to renewable fuels. When Ergon filed for an extension of the small refinery
    exemption, the EPA denied its petition on the basis that Ergon’s participation in the
    program would not constitute a disproportionate economic hardship. Ergon petitions the
    Court for review of the EPA’s denial. Because we conclude that the EPA’s decision was
    arbitrary and capricious, we grant Ergon’s petition for review, vacate the EPA’s denial,
    and remand for further proceedings.
    I.
    We begin with the renewable fuels statute and its history and then turn to the
    proceedings in this case.
    A.
    With the Energy Policy Act of 2005, Congress added the renewable fuel standard
    program (the “RFS Program” or “Program”) as Section 211(o) of the Clean Air Act. See
    42 U.S.C. § 7545(o). The statute directs the EPA Administrator to promulgate regulations
    “to ensure that transportation fuel sold or introduced into commerce in the United States
    (except in noncontiguous States or territories), on an annual average basis, contains at
    least the applicable volume of renewable fuel, advanced biofuel, cellulosic biofuel, and
    3
    biomass-based diesel” 1 required by the Program. 
    Id. § 7545(o)(2)(A)(i).
    Renewable fuels,
    such as ethanol, are those that are “produced from renewable biomass and that [are] used
    to replace or reduce the quantity of fossil fuel present in a transportation fuel.” 
    Id. § 7545(o)(1)(J).
    Renewable biomass includes natural materials such as crops, trees, and
    animal byproducts. 
    Id. § 7545(o)(1)(I).
    The regulations apply “to refineries, blenders,
    distributors, and importers.” 
    Id. § 7545(o)(2)(A)(iii)(I).
    The applicable volumes of renewable fuel, advanced biofuel, cellulosic biofuel,
    and biomass-based diesel that transportation fuels must contain on an industry-wide basis
    are found in § 7545(o)(2)(B). For instance, the statute lists the applicable volume of
    renewable fuel for 2016 as 22.25 billion gallons. 
    Id. § 7545(o)(2)(B)(i)(I).
    To determine
    the “applicable percentages” of renewable fuel, advanced biofuel, cellulosic biofuel, and
    biomass-based diesel that a facility must use, the EPA first estimates “the volumes of
    transportation fuel, biomass-based diesel, and cellulosic biofuel projected to be sold or
    introduced into commerce in the United States” the following year. 
    Id. § 7545(o)(3)(A).
    The EPA then divides the applicable volume of the particular renewable fuel by the fuel
    estimate to arrive at the percentage every refinery must meet and publishes it in the
    Federal Register. 
    Id. § 7545(o)(3)(B);
    40 C.F.R. § 80.1405. For example, the percentage
    of renewable fuel for 2016 was 10.10%. 40 C.F.R. § 80.1405(a)(7)(iv). This
    1
    Although the RFS Program sometimes lists these four fuels separately, it also often
    terms them all as “renewable fuel,” perhaps because the definitions of advanced biofuel,
    cellulosic biofuel, and biomass-based diesel all refer to those fuels as renewable fuel. See 42
    U.S.C. § 7545(o)(1)(B), (D), (E); see also 40 C.F.R. § 80.1401. The U.S. Department of Energy
    has called the four fuel categories “‘nested’ standards.” J.A. 19.
    4
    percentage—or “renewable fuel obligation”—is “applicable to refineries, blenders, and
    importers, as appropriate,” 2 and is “expressed in terms of a volume percentage of
    transportation fuel sold or introduced into commerce in the United States.” 42 U.S.C.
    § 7545(o)(3)(B)(ii). A refinery will multiply the percentage by the volume of
    nonrenewable fuel that it produces or imports to determine its “renewable volume
    obligation.” 40 C.F.R. § 80.1407.
    All renewable fuels are identified by a renewable identification number (“RIN”),
    which “is a unique number generated to represent a volume of renewable fuel.” 40 C.F.R.
    § 80.1401. An obligated party must “separate” a sufficient number of RINs (i.e., blend
    the renewable fuel with nonrenewable fuel) to demonstrate compliance with the Program.
    See 
    id. §§ 80.1427–80.1429;
    see also 42 U.S.C. § 7545(o)(5) (establishing a credit
    program for blending renewable fuels with transportation fuels). If the obligated party
    fails to separate the required number of RINs, it can purchase separated RINs from a
    party who has separated more RINs than it needs and thereby avoid violating the
    Program’s    requirements and        incurring       penalties.   See 40   C.F.R. §§ 80.1428,
    80.1460(c)(1); see also 42 U.S.C. § 7545(o)(5)(B) (stating that “[a] person that generates
    credits . . . may use the credits, or transfer all or a portion of the credits to another person,
    for the purpose of complying with [the Program]”).
    From 2005 until 2011, small refineries—those “for which the average aggregate
    daily crude oil throughput for a calendar year . . . does not exceed 75,000 barrels,” 42
    2
    Despite the statute’s instruction, the EPA defines an “obligated party” under the RFS
    Program as a refiner or importer and specifically exempts blenders. 40 C.F.R. § 80.1406(a)(1).
    5
    U.S.C. § 7545(o)(1)(K); see also 40 C.F.R. § 80.1442—were exempt from the Program,
    42 U.S.C. § 7545(o)(9)(A)(i); see also 40 C.F.R. § 80.1441. The statute directed the
    Secretary of the Department of Energy to “conduct for the [EPA] Administrator a study
    to determine whether compliance with the [Program’s] requirements . . . would impose a
    disproportionate       economic      hardship        on    small    refineries.”      42   U.S.C.
    § 7545(o)(9)(A)(ii)(I) (emphasis added). If the DOE determined that a given refinery
    would experience disproportionate economic hardship, then the EPA Administrator was
    required   to   extend    the     facility’s   exemption     for   at   least   two    years.   
    Id. § 7545(o)(9)(A)(ii)(II).
    After this first mandatory extension period, the statute provides
    that a facility may petition the EPA for extension of the exemption “at any time” due to
    disproportionate economic hardship. 
    Id. § 7545(o)(9)(B)(i).
    This petition “must specify
    the factors that demonstrate a disproportionate economic hardship and must provide a
    detailed discussion regarding the hardship the refinery would face in producing
    transportation fuel meeting the [Program’s] requirements.” 40 C.F.R. § 80.1441(e)(2)(i).
    In evaluating the petition, the EPA—“in consultation with” the DOE—must “consider the
    findings of the [DOE’s] study             . . . and other economic factors.” 42 U.S.C.
    § 7545(o)(9)(B)(ii).
    B.
    In 2009, the DOE presented the EPA with the Small Refineries Exemption Study
    (the “2009 Study”), as required by 42 U.S.C. § 7545(o)(9)(A)(ii)(I). The 2009 Study
    recognized that “[o]bligated parties, such as refineries, may fulfill their renewable fuel
    requirements through either blending renewable fuels into their products or purchasing
    6
    credits from other parties who have exceeded their allocation of renewable fuel
    consumption.” J.A. 15. The DOE determined that, “[a]s long as credits are available for
    purchase and the market is competitive, small refineries should not be subject to
    disproportionate economic hardship from their choice to purchase credits rather than to
    generate them.” J.A. 15. 3 The 2009 Study concluded that the general small refinery
    exemption should not be extended beyond 2010, based largely on its determination that
    “credits are available at a nominal value and compliance volumes have been in excess of
    the RFS requirements.” J.A. 16.
    Unsatisfied with this result, Congress directed the DOE to conduct a new, more in-
    depth analysis. 4 The DOE released this new study in 2011 (the “2011 Study”). The 2011
    3
    The 2009 Study did recognize, however, that “[i]t [was] too early to project whether
    [RIN] markets will continue to be liquid and competitive.” J.A. 27.
    4
    Congress provided this directive in a Senate report, stating the following:
    The January 2009 Small Refineries Exemption Study issued by the
    Department of Energy was intended to determine whether small refineries faced a
    disproportionate economic hardship in meeting Renewable Fuel Standard [RFS]
    requirements beginning in 2011. The Committee understands the study contained
    inadequate small refinery input, did not assess the economic condition of the
    small refining sector, take into account regional factors or accurately project RFS
    compliance costs. Therefore, the Committee does not believe the study is
    complete, nor is the Department able to make the required determination at this
    time. In view of these deficiencies and the importance of the study, the
    Department is directed to reopen and reassess the Small Refineries Exemption
    Study by June 30, 2010. The Department is specifically directed to seek and invite
    comment from small refineries on the RFS exemption hardship question, assess
    RFS compliance impacts on small refinery utilization rates and profitability,
    evaluate the financial health and ability of small refineries to meet RFS
    requirements, study small refinery impacts and regional dynamics by PADD, and
    reassess the accuracy of small refinery compliance costs through the purchase of
    renewable fuel credits. Finally, the Committee notes that the 2009 study does not
    estimate the price of tradable fuel credits, but the Committee is aware that from
    2008 to 2009, price has increased nearly threefold. The Committee expects the
    (Continued)
    7
    Study defined disproportionate economic hardship as “increased cost of compliance to
    the point that the current or future viability of the refinery is impacted.” J.A. 47. The
    DOE recognized that:
    [s]mall refineries can suffer disproportionate economic hardship from
    compliance with the RFS program if blending renewable fuel into their
    transportation fuel or purchasing RINs increases their cost of products
    relative to competitors to the point that they are not viable, either due to
    loss of market share or lack of working capital to cover the costs of
    purchasing RINs.
    J.A. 47. 5 After conducting a survey of small refineries, the DOE created a scoring matrix
    composed of two indices—the “Disproportionate Impact Index” and the “Viability
    Index”—to be used to determine whether a small refinery suffers disproportionate
    economic hardship:
    Department to undertake an economic review to estimate the actual economic
    impact of the RFS on small refineries on a regional basis.
    S. Rep. No. 111-45, at 109 (2009).
    5
    The EPA later disagreed with the DOE’s statement that purchasing RINs may put a
    small refinery at an economic disadvantage, stating the following:
    EPA notes that after further review, contrary to statements in [the 2011 Study], it
    has been found that a refinery does not experience disproportionate economic
    hardship simply because it may need to purchase a significant percentage of its
    RINs for compliance from other parties, even though RIN prices have increased
    since the DOE study, because the RIN prices lead to higher sales prices obtained
    for the refineries’ blendstock, resulting in no net cost of compliance for the
    refinery.
    J.A. 317.
    8
    9
    J.A. 82, 85.
    In Section 1(a) of the Disproportionate Impact Index, the DOE assesses the small
    refinery’s access to capital and credit, primarily through its credit rating. Section 1(b)
    considers a refinery’s business lines other than refining and marketing—“in particular
    upstream operations such as exploration and development that are less correlated with
    refining”—which may insulate the refinery from the volatility of refining margins. J.A.
    83. Section 1(c) accounts for the refinery’s geographic location by evaluating how likely
    the local market will accept transportation fuels blended with renewable fuels. Although
    the category lists subcategories for E10 (a fuel mixture of 10% ethanol and 90%
    gasoline), E85 (a fuel mixture of 85% ethanol and 15% gasoline), and biodiesel, the latter
    two are “[r]eserved for later evaluation.” J.A. 83. Section 1(d) evaluates a refinery’s
    percentage of diesel production in recognition of the fact that “refineries that
    disproportionately favor diesel production over gasoline inherently have a more difficult
    compliance pathway, as the percentage of renewable fuel available to blend into diesel is
    much lower than the 10 percent of ethanol that can be blended into gasoline.” J.A. 83.
    10
    Section 1(e) contemplates abnormally strict state regulations, such as those states that
    “require refiners to sell unblended fuel.” J.A. 83.
    In Section 2(a), the DOE scores the refinery for its relative refining margin—
    essentially its refining revenue minus its refining costs, or refining profit—compared to
    the three-year industry average. Section 2(b) evaluates the capacity of the refinery to
    blend its nonrenewable fuels with renewable fuels, with a lower capacity indicating
    greater impairment. Although Section 2(b) has subcategories of ethanol, biodiesel, and
    advanced biofuels, only the first is scored, with the others “[r]eserved for later
    evaluation.” J.A. 84. Section 2(c) considers whether a refinery operates in a niche
    market—such as a refinery that is located in a region “with limited alternative finished
    product supply or access to distressed crude oil supply” or one that produces “a specialty
    slate of products” like “lube oils, greases, asphalt, etc.” in addition to transportation
    fuels—as the refinery’s participation in the niche market may “result in higher than
    industry refining margins.” J.A. 84. In Section 2(d), the DOE determines whether the
    refinery generates revenue by selling RINs or must purchase RINs in the market. The
    2011 Study stated that “[t]his criterion was not utilized in the current assessment due to
    lack of consistency among the survey participants.” J.A. 84.
    The Viability Index analyzes “the ability of the refiners to remain competitive and
    profitable” while complying with the Program. J.A. 85. In Section 3(a), the DOE
    determines the degree to which a facility’s cost of compliance impairs its ability to make
    efficiency improvements. Section 3(b) accounts for any events such as a temporary
    shutdown that may prevent the facility from fully complying with the RFS Program’s
    11
    requirements. Section 3(c) evaluates the likelihood that compliance costs will cause a
    refinery to shut down.
    The DOE averages the scores in a given index and divides the average by 2. A
    refinery is entitled to an exemption if it achieves a score greater than 1 in both indices. To
    obtain this score, a facility must earn “a score equivalent to at least four of the eight
    metrics for disproportionate impact at the moderate level (5)” and “a positive value for at
    least one of the three metrics for” the Viability Index. J.A. 86.
    In 2015, Congress directed the DOE “to recommend to the EPA Administrator a
    50 percent waiver of RFS requirements” if a refinery reaches the requisite score on only
    one of the two indices. 161 Cong. Rec. H10,105 (daily ed. Dec. 17, 2015). Congress also
    stated the following:
    The [DOE] Secretary is reminded that the RFS program may impose a
    disproportionate economic hardship on a small refinery even if the refinery
    makes enough profit to cover the cost of complying with the program.
    Small refinery profitability does not justify a disproportionate regulatory
    burden where Congress has explicitly given EPA authority, in consultation
    with the Secretary, to reduce or eliminate this burden.
    
    Id. Finally, in
    December 2016, the EPA issued a memorandum that detailed how it
    evaluates small-refinery-exemption petitions. The EPA “considers the findings of the
    DOE Small Refinery Study and a variety of economic factors.” J.A. 201. Some of those
    factors include “profitability, net income, cash flow and cash balances, gross and net
    refining margins, ability to pay for small refinery improvement projects, corporate
    structure, debt and other financial obligations, RIN prices, and the cost of compliance
    12
    through RIN purchases.” J.A. 201. Petitioning facilities include financial information
    with their petitions to aid the EPA in its analysis.
    C.
    Ergon owns a refinery in Newell, West Virginia, with a maximum crude oil
    capacity of 23,000 barrels per day, well under the small refinery threshold. The facility
    primarily produces paraffinic lube oils, and the transportation fuels it produces are
    byproducts of that lube oil production. 6 Nearly all (99%) of Ergon’s transportation fuels
    are sold within a 170-mile radius of the facility.
    In April 2016, Ergon filed a petition with the EPA for a small refinery exemption
    for compliance years 2014, 2015, and 2016. In its petition, Ergon claimed that it is at an
    economic disadvantage because, while there was a widespread market for blended
    gasoline, there was no such market for blended diesel. Ergon also claimed that its ability
    to comply with the Program was limited by its geographic location because customers in
    Ergon’s market chose its main competitor’s unblended diesel over Ergon’s blended
    diesel. See J.A. 216 (“Because [Ergon] produces diesel at nearly twice the industry
    average and biodiesel is blended at lower rates than gasoline, [Ergon] generates fewer
    RINs for compliance than a large, vertically integrated refiner like [Ergon’s main
    competitor].”). 7
    6
    Approximately two-thirds of the transportation fuel Ergon produces is diesel, with the
    other third gasoline.
    7
    Ergon does have the infrastructure to blend ethanol into its gasoline.
    13
    In June 2016, the EPA denied Ergon’s petition for years 2014 and 2015. The DOE
    applied the scoring matrix for those years and concluded that Ergon did not achieve the
    requisite scores on either the Disproportionate Impact Index or the Viability Index. For
    both years, the DOE gave Ergon scores of 0 for Sections 1(a), 1(b), 1(c), 1(e), and 2(a)
    through 2(c) in the Disproportionate Impact Index. However, the DOE gave Ergon a
    score of 10 for Section 1(d) due to its high level of diesel production. The DOE did not
    give Ergon a score for Section 2(d)—the “RINs net revenue or cost” factor—because it
    “has not scored this category for any hardship petition evaluations.” J.A. 260. With a total
    of ten points, the average across the eight scored sections was 1.25. After dividing that
    figure by 2, Ergon’s overall score for the Disproportionate Impact Index was 0.6. The
    DOE gave Ergon a score of 0 for each of the three sections of the Viability Index,
    resulting in an overall score of 0. The EPA reviewed the DOE’s scoring matrix and
    “independently determine[d]” that Ergon “w[ould] not experience ‘disproportionate
    economic hardship’ from compliance with the RFS program for 2014 and 2015.” J.A.
    262. In short, the EPA “agree[d] with DOE’s determination in reviewing [Ergon’s]
    petition that [Ergon’s] 2014 and 2015 RFS compliance costs do not threaten [Ergon’s]
    viability.” J.A. 264.
    In August 2016, Ergon withdrew its 2016 petition, informed the EPA that it would
    file a revised petition for that year, and asked the EPA to reconsider its decision for
    14
    2015. 8 In December 2016, Ergon submitted the revised petition for the 2016 compliance
    year. In May 2017, the EPA denied Ergon’s 2016 petition for a small refinery exemption.
    The EPA again relied on the DOE’s determination (the “DOE’s Report”) that Ergon
    achieved the same deficient scores as in the 2014 and 2015 evaluations:
    8
    Ergon did not request reconsideration of the 2014 decision “because the compliance
    deadline ha[d] passed.” J.A. 268.
    15
    16
    J.A. 326–27. Unlike the 2014 and 2015 denials, however, the EPA did not focus on
    Ergon’s viability specifically in its denial of the 2016 petition.
    Ergon filed a timely petition for review of the EPA’s final agency action regarding
    only the 2016 petition. The Court has jurisdiction pursuant to 42 U.S.C. § 7607(b)(1).
    II.
    Ergon makes two overarching arguments in its challenge of the EPA’s denial of its
    2016 petition. 9 First, Ergon argues that the EPA’s decision was arbitrary, capricious, and
    contrary to law because it adopted the DOE’s “error-riddled analysis” of Ergon’s petition.
    Opening Br. 23. Second, Ergon contends that the EPA’s conclusion was contrary to law
    insofar as it read an extra-statutory “viability requirement” into § 7545(o)(9)(B)’s
    “disproportionate economic hardship” determination. While we reject the latter argument,
    the former is well-taken. We therefore vacate the EPA’s decision and remand for further
    proceedings. 10
    9
    At the outset, we reject the EPA’s assertion that Ergon has waived some of its legal
    arguments because it did not raise them during the administrative process. We fail to see how
    Ergon could have raised legal arguments addressing the EPA’s alleged errors in denying its
    petition before the EPA had actually denied the petition. Nor do we accept the EPA’s contention
    that Ergon should have made those legal arguments within its 2016 petition because it knew the
    bases for the EPA’s denial of its petition for compliance years 2014 and 2015. See Sinclair Wyo.
    Ref. Co. v. U.S. EPA, 
    887 F.3d 986
    , 992 (10th Cir. 2017) (“Indeed, the [EPA’s] decisions have
    no precedential value even for the refiner, since each petition must be resolved on a case-by-case
    basis . . . .”).
    10
    This is a case of first impression in this Court. In fact, the EPA’s application of the
    small refinery exemption has been challenged only three times, with each of those cases focused
    on the EPA’s application of a viability requirement. In Hermes Consol., LLC v. EPA, 
    787 F.3d 568
    , 574–75, 579–80 (D.C. Cir. 2015), the court rejected a refinery’s challenge to the EPA’s
    heavy reliance on the DOE’s analysis of its petition, particularly the Viability Index, but it

    This Court must “hold unlawful and set aside agency action, findings, and
    conclusions” that are “arbitrary, capricious, an abuse of discretion, or otherwise not in
    accordance with law.” 5 U.S.C. § 706(2)(A). Although we accord substantial deference to
    an agency’s final action and presume it valid, “the arbitrary-and-capricious standard does
    not reduce judicial review to a rubber stamp of agency action.” Friends of Back Bay v.

    Congress did not intend for it to consider, entirely ignores important aspects of the
    problem, explains its decision in a manner contrary to the evidence before it, or reaches a
    decision that is so implausible that it cannot be ascribed to a difference in view.” United

    792 F.3d 978
    , 982–83, 984 (8th
    Cir. 2015), the court likewise rejected a refinery’s contention that the EPA erred in relying on the
    DOE’s analysis of its petition, with the EPA’s denial again focusing on the Viability Index. And
    in Sinclair, the Tenth Circuit found reversible error when the EPA rejected the DOE’s
    recommendation that a refinery receive a 50% waiver of the RFS Program requirements because
    the EPA had determined that the Program would not affect the refinery’s viability. 
    See 887 F.3d at 995
    –99. Again, all of these cases involve the EPA’s rejection of the refineries’ petitions
    because it concluded that the RFS Program did not threaten their viability. None of the cases
    specifically address the Disproportionate Impact Index—primarily the metric at issue here.
    18
    reliance on the DOE’s analysis of Ergon’s 2016 petition; and (2) acted contrary to law in
    determining that Ergon would not receive a waiver because compliance with the RFS
    Program would not threaten its viability. We address each argument in turn.
    1.
    Ergon makes several arguments attacking the DOE’s conclusions, but we are
    limited in our consideration of these arguments. The DOE’s Report itself cannot be
    challenged directly in this case. Ergon did not sue the DOE for issuing its
    recommendation; 11 rather, it sued the EPA—the action agency—for denying its 2016
    waiver petition. Therefore, instead of determining whether the DOE’s Report is arbitrary
    and capricious, we may consider only whether the EPA’s reliance on the DOE’s Report
    is arbitrary and capricious. See Dow AgroSciences LLC v. Nat’l Marine Fisheries Serv.,
    
    637 F.3d 259
    , 266–67 (4th Cir. 2011) (“When a court of appeals reviews the EPA’s
    reliance on a [report issued by another agency], it would determine only whether the
    EPA’s reliance was arbitrary and capricious.”); City of Tacoma v. FERC, 
    460 F.3d 53
    , 75
    (D.C. Cir. 2006) (“Accordingly, when we are reviewing the decision of an action agency
    to rely on [another agency’s report], the focus of our review is quite different than when
    we are reviewing a [report] directly. In the former case, the critical question is whether
    the action agency’s reliance was arbitrary and capricious, not whether the [report] itself is
    somehow flawed.”). While the action agency is not required “to undertake an
    independent analysis” of another agency’s conclusions, it may not “blindly adopt [those]

    We express no opinion on whether such a report might be subject to direct judicial
    review in a separate action.
    19
    conclusions.” City of 
    Tacoma, 460 F.3d at 76
    . Thus, an action agency’s reliance on a
    facially-flawed report is arbitrary and capricious. See 
    id. at 75.
    With these legal principles
    in mind, we turn to Ergon’s arguments.
    2.
    Ergon first contends that the DOE erred in scoring two factors within the
    Disproportionate Impact Index by arbitrarily defining “refining” to Ergon’s detriment. In
    Section 1(b) (the “other business lines besides refining and marketing” factor), the DOE
    separated Ergon’s refining from its lube oil production, considered the latter as an “other
    business line[] besides refining and marketing,” and gave Ergon a score of 0 for this
    factor. Then, in Section 2(a) (the “relative refining margin” factor), the DOE treated
    Ergon’s lube oil production as refining for purposes of the relative refining margin
    measure, again resulting in a score of 0. Both of these decisions negatively impacted
    Ergon’s score. Despite this apparent contradiction, however, these arguments go to the
    DOE’s scoring methodology and are not apparent on the face of the DOE’s Report.
    Therefore, we cannot say that the EPA’s reliance on the DOE’s scoring of these factors
    was arbitrary and capricious.
    3.
    Ergon next posits that the DOE erred by failing to score Section 1(c) (the “local
    market acceptance of renewables” factor), Section 2(b) (the “renewable fuel blending”
    factor), and Section 2(d) (the “RINs net revenue or cost” factor). The DOE’s failure to
    score these factors is apparent on its face, and Ergon contends that the DOE’s arbitrary
    treatment of these sections actively hurt its petition. Because our analysis of Sections 1(c)
    20
    and 2(b) differs slightly from that of Section 2(d), we provide separate discussions of
    these factors below.
    a.
    In Section 1(c), the DOE accords points depending on the acceptance of renewable
    fuel in the refinery’s local market. There are three subcategories within this factor: E10,
    E85, and biodiesel renewables. The DOE did not score the latter two subcategories at all
    in analyzing Ergon’s petition and has apparently never scored those subcategories in any
    refinery’s petition. Instead, the DOE gave Ergon’s petition a score of 0 for the local
    market’s acceptance of E10, completely disregarding the fact that approximately two-
    thirds of Ergon’s transportation fuel production is diesel, which must be mixed with
    biodiesel. The DOE treated Section 2(b)—which measures a refinery’s capacity for
    blending renewable fuels with nonrenewable fuels—similarly. Although Section 2(b) has
    subcategories for ethanol, biodiesel, and advanced biofuel blending, the DOE scored only
    the first, ignoring Ergon’s biodiesel blending and giving Ergon a score of 0 for this
    category. Had Ergon achieved a score of 10 on either Section 1(c) or Section 2(b), it
    would have achieved a score greater than 1 and likely earned a small refinery
    exemption. 12
    12
    The DOE’s analysis of Ergon’s 2016 petition resulted in a total score of 0.6 for the
    Disproportionate Impact Index and a total score of 0 for the Viability Index. In the
    Disproportionate Impact Index, the DOE gave Ergon ten points for Section 1(d) (the “percentage
    of diesel production” factor) and no points for the other factors. With eight sections in this index
    (not counting the “RINs net revenue or cost” factor, which the DOE did not score and has never
    applied to any facility), the average was 1.25. After dividing by 2, the DOE reached the total
    score of 0.6. Ergon needed a total of twenty points in this Index to achieve a score greater than 1.
    (Continued)
    21
    The DOE’s treatment of these two factors—Sections 1(c) and 2(b)—is plainly
    arbitrary as it treats unfairly those facilities where diesel makes up a substantial
    percentage 13 of their transportation fuel production. For Section 1(c), despite the
    widespread acceptance of E10 gasoline, a local market may not readily accept diesel
    blended with biodiesel, placing refineries with higher-than-average production of diesel,
    like Ergon, at a measurable disadvantage, as the DOE recognized in its 2011 Study. See
    J.A. 71 (noting that, “[i]n most states, biodiesel blending is limited because biodiesel
    feedstock is expensive and consumer resistance to the blend exists”). Similarly, in
    Section 2(b), while a facility may have a high capacity to blend ethanol with its
    nonrenewable fuel, it may not have the same capacity to blend biodiesel, so failing to
    score this factor again harms those facilities with higher-than-average production of
    diesel, like Ergon. These errors are readily apparent on the face of the DOE’s Report as
    the index lists “[n]ot available” next to biodiesel in Section 1(c) and “not used” next to
    biodiesel blending in Section 2(b). J.A. 326. Because the DOE’s recommendation was
    clearly flawed on its face, “a clear error of judgment was made” when the EPA relied
    without explanation on the DOE’s Report for its denial of Ergon’s 2016 waiver petition.
    Ohio Valley Envtl. Coal. v. Aracoma Coal Co., 
    556 F.3d 177
    , 192 (4th Cir. 2009). In
    Had the DOE scored either Section 1(c) or Section 2(b), Ergon likely would have earned at least
    a partial exemption.
    13
    While diesel makes up almost two-thirds of Ergon’s transportation fuel production, the
    industry average is for diesel to constitute less than one-third of a given refinery’s transportation
    fuel production.
    22
    addition, the EPA did not conduct any independent analysis regarding the subject matter
    of Sections 1(c) and 2(b).
    Nonetheless, the EPA argues that its consideration of the DOE’s analysis was only
    one of several grounds for denying Ergon’s petition. To be sure, the EPA stated in its
    denial letter that it “independently review[ed] the information” and “consider[ed] other
    economic factors in [its] analysis.” J.A. 327. But the extent to which the EPA relied on
    the DOE’s Report and the relative weight of Sections 1(c) and 2(b) are unknown. In its
    denial letter to Ergon, the EPA stated, “In determining whether [Ergon] will experience
    disproportionate economic hardship, EPA considers whether compliance with its RFS
    obligations disproportionately impacts [Ergon]. EPA generally defers to DOE’s
    assessment due to DOE’s expertise on the refining industry.” J.A. 327 (emphasis added);
    accord J.A. 320 (“EPA considers DOE’s assessment of whether a small refinery will face
    disproportionate impacts in complying with its RFS obligations. The DOE analysis
    informs EPA’s finding of whether ‘disproportionate economic hardship’ exists and in
    turn EPA’s resulting decision about whether to grant or deny a petition for an extension
    of the RFS temporary exemption for a small refinery.”). On this record, we cannot
    determine whether the EPA would have reached the same conclusion had the DOE
    submitted a proper analysis or had the EPA addressed the DOE’s failure to analyze
    Sections 1(c) and 2(b). Although the EPA acknowledged that “disproportionate impacts
    could disadvantage a refinery relative to the industry average and make compliance with
    RFS obligations relatively more burdensome,” it specifically recognized that the “DOE
    did not find that [Ergon] demonstrated disproportionate economic and structural impacts”
    23
    (i.e., did not achieve the requisite score in the Disproportionate Impact Index). J.A. 328.
    Although the EPA is statutorily required to consider the DOE’s recommendation, it may
    not turn a blind eye to errors and omissions apparent on the face of the report, which
    Ergon pointed out and the EPA did not address in any meaningful way. City of 
    Tacoma, 460 F.3d at 76
    (“[T]he action agency must not blindly adopt the conclusions of the
    consultant agency, citing that agency’s expertise.”). In doing so, the EPA “ignore[d]
    important aspects of the problem.” F/V Alice 
    Amanda, 987 F.2d at 1085
    .
    b.
    Section 2(d) considers whether a facility generates revenue by selling RINs or
    suffers costs by purchasing RINs on the market. Like Sections 1(c) and 2(b), the DOE’s
    failure to score this section is apparent on the face of the DOE’s Report, and that failure
    negatively impacted Ergon’s petition. Unlike Sections 1(c) and 2(b), however, the EPA’s
    reliance on the DOE’s Report regarding Section 2(d) was not arbitrary and capricious in
    and of itself as the EPA did not rely on that factor in its determination. See J.A. 317
    (discussing the 2011 Study in general and stating that “EPA notes that after further
    review, contrary to statements [in the 2011 Study], it has been found [in an EPA study]
    that a refinery does not experience disproportionate economic hardship simply because it
    may need to purchase a significant percentage of its RINs for compliance from other
    parties, even though RIN prices have increased since the [2011 Study], because the RIN
    prices lead to higher sales prices obtained for the refineries’ blendstock, resulting in no
    net cost of compliance for the refinery”). Because the EPA provided a specific response
    addressing why it did not consider the 2011 Study’s conclusions concerning RIN
    24
    prices—thereby implicitly disregarding the scoring of the factor in the DOE’s Report—
    the EPA’s reliance on the DOE’s Report as to Section 2(d) was not arbitrary and
    capricious.
    Even so, the EPA’s analysis of the effect of RIN prices on Ergon’s refining facility
    was arbitrary and capricious on this record because the EPA ignored specific evidence
    suggesting that those prices had a negative effect. In that regard, Ergon points out that the
    EPA’s analysis of its RIN costs consists of a solitary statement: “EPA acknowledges that
    [Ergon] may not be able to satisfy its [Program obligations] exclusively through the
    blending of ethanol and biodiesel into its gasoline and diesel; however, the mere fact that
    [Ergon] needs to purchase RINs for compliance does not necessarily entitle [Ergon] to an
    exemption.” J.A. 330. The EPA cites to an EPA study titled “A Preliminary Assessment
    of RIN Market Dynamics, RIN Prices, and Their Effects” for this conclusion. That study,
    according to the EPA, merely determined that the refining industry as a whole is not
    burdened by rising RIN prices because refineries may pass that cost to purchasers of the
    blended fuel. Ergon’s 2016 petition, however, maintains that its refinery cannot pass the
    RIN costs on to purchasers because of the local market’s low acceptance of blended
    diesel. See 161 Cong. Rec. H10,105 (daily ed. Dec. 17, 2015) (“Since [the 2011 Study],
    the dramatic rise in RIN prices has amplified RFS compliance and competitive
    disparities, especially where unique regional factors exist, including high diesel demand,
    no export access, and limited biodiesel infrastructure and production.”); J.A. 71
    (recognizing in the 2011 Study that, “[i]n most states, biodiesel blending is limited
    because biodiesel feedstock is expensive and consumer resistance to the blend exists”).
    25
    Insomuch as the EPA cited generally to an industry-wide study and a nonspecific
    nationwide trend to find that RIN prices would not harm Ergon although Ergon provided
    specific, contradictory evidence of hardship particular to its refinery due to RIN costs,
    the EPA failed to squarely address Ergon’s petition with regards to RIN costs and
    “explain[ed] its decision in a manner contrary to the evidence before it.” F/V Alice
    
    Amanda, 987 F.2d at 1085
    . Furthermore, the EPA’s disregard for Ergon’s RIN arguments
    appears inconsistent with its statement earlier in the 2016 decision that the EPA considers
    “RIN prices[] and the cost of compliance through RIN purchases” in making its
    determination. J.A. 327; accord J.A. 201 (explaining in a December 2016 memorandum
    that the EPA considers “RIN prices[] and the cost of compliance through RIN purchases”
    in evaluating a petition). Consequently, the EPA’s cursory consideration and failure to
    address Ergon’s specific evidence regarding RIN costs was an arbitrary and capricious
    action. This failure alone warrants granting Ergon’s petition for review.
    ****
    Because the EPA relied on the DOE’s facially-deficient recommendation to an
    unexplained and unknown degree, and because the EPA failed to properly address
    Ergon’s petition with regard to RIN costs, we must vacate the EPA’s decision to deny
    Ergon’s 2016 petition as arbitrary and capricious. See Hermes Consol., LLC v. EPA, 787
    
    26 F.3d 568
    , 571 (D.C. Cir. 2015) (“[W]e are unable to conclude that EPA would have
    reached the same decision absent its mistakes.”). 14
    4.
    Ergon next argues that the EPA read a viability requirement into the definition of
    “disproportionate economic hardship” 15 and rejected Ergon’s waiver petition primarily
    because compliance with the RFS Program would not threaten Ergon’s viability. 16 Ergon
    urges us to adopt the Tenth Circuit’s reasoning in Sinclair Wyoming Refining Co. v. U.S.
    EPA, 
    887 F.3d 986
    (10th Cir. 2017), and hold that the EPA erred in this case by applying
    this viability requirement. However, while it does appear that the EPA applied some sort
    14
    At this time, we neither endorse nor find fault with the remaining grounds that the EPA
    contends support its denial of Ergon’s petition.
    15
    The parties dispute whether the Court should accord Chevron or Skidmore deference to
    the EPA’s interpretation of the term “disproportionate economic hardship” found in 42 U.S.C.
    § 7545(o)(9). Compare Chevron, U.S.A., Inc. v. Nat. Res. Def. Council, Inc., 
    467 U.S. 837
    , 843
    (1984) (holding that, “if the statute is silent or ambiguous with respect to the specific issue, the
    question for the court is whether the agency’s answer is based on a permissible construction of
    the statute”), with Skidmore v. Swift & Co., 
    323 U.S. 134
    , 140 (1944) (holding that a court will
    determine how much weight to give an agency’s rulings “depend[ing] upon the thoroughness
    evident in its consideration, the validity of its reasoning, its consistency with earlier and later
    pronouncements, and all those factors which give it power to persuade, if lacking power to
    control”). We do not decide this standard-of-review question because we otherwise find no merit
    in Ergon’s argument on the issue raised.
    16
    Couched within the viability argument section of Ergon’s opening brief, Ergon
    discusses at some length the DOE’s allegedly erroneous calculation of the industry average
    refining margins and comparison of those margins to Ergon’s refining margins. From that
    discussion, Ergon presumably argues that the EPA erred in relying on those figures when
    assessing Ergon’s 2016 petition. Assuming without deciding that blind reliance on the DOE’s
    calculations would constitute per se error, Ergon fails to recognize that the EPA independently
    calculated the industry average refining margins. Compare J.A. 323–24 (the EPA’s calculation
    of three-year average refining margins for the years 2014 through 2016), with J.A. 326 (the
    DOE’s calculation of three-year average refining margins for the years 2013 through 2015).
    Because Ergon does not challenge the EPA’s independent calculation, we do not consider
    Ergon’s argument.
    27
    of viability test in its denial of Ergon’s petition for compliance years 2014 and 2015,
    there is no indication it used a similar viability requirement in the 2016 petition denial—
    the sole decision of the EPA at issue in this case. Compare J.A. 262–65 (2014 & 2015
    denial), with J.A. 327–30 (2016 denial); see also J.A. 320 (“In prior decisions, EPA
    considered that a small refinery could not show disproportionate economic hardship
    without showing an effect on ‘viability,’ but we are changing our approach. While a
    showing of a significant impairment of refinery operations may help establish
    disproportionate economic hardship, compliance with RFS obligations may impose a
    disproportionate economic hardship when it is disproportionately difficult for a refinery
    to comply with its RFS obligations—even if the refinery’s operations are not significantly
    impaired.”). At most, it appears that the EPA considered viability as only one factor in its
    2016 decision, which it was permitted to do. 
    Sinclair, 887 F.3d at 996
    (“If long-term
    ‘viability’ was merely one element the EPA considered in its ‘disproportionate economic
    hardship’ analysis, that would be a different story.”). Accordingly, we find no merit to
    Ergon’s contention on this issue.
    III.
    For these reasons, we grant Ergon’s petition for review, vacate the EPA’s
    decision, and remand the case to the EPA for further proceedings consistent with this
    opinion.
