    TYMKOVICH, Chief Judge.
    In an amendment to the Clean Air Act (CAA), Congress directed the EPA
    to operate a Renewable Fuel Standards Program (the RFS Program) to increase oil
    refineries’ use of renewable fuels. But for small refineries that would suffer a
    “disproportionate economic hardship” in complying with the RFS Program, the
    statute required the EPA to grant exemptions on a case-by-case basis.
    We conclude the EPA has exceeded its statutory authority under the CAA
    in interpreting the hardship exemption to require a threat to a refinery’s survival
    as an ongoing operation. That interpretation is outside the range of permissible
    interpretations of the statute and therefore inconsistent with Congress’s statutory
    mandate. Because we find that the EPA exceeded its statutory authority, we
    vacate the EPA’s decisions and remand to the EPA for further proceedings.
    I. Background
    In the Energy Policy Act of 2005, Congress amended the CAA to encourage
    the use of renewable fuels. The statute’s RFS program requires oil refineries to
    either produce a sufficient proportion of renewable fuels as part of their output or
    purchase credits generated by other refineries to meet their increased renewable-
    fuel obligations. See 42 U.S.C. § 7545(o); 40 C.F.R. § 80.1429. But Congress
    -2-
    also directed that small refineries may receive a statutory exemption if
    participation in the program would cause them “disproportionate economic
    hardship.” 42 U.S.C. § 7545(o)(9)(B).
    A. The Renewable Fuel Standards Program
    Through the RFS Program, Congress prescribed annual target volumes for
    renewable fuel sales, which increase each year until reaching a maximum level in
    2022. 1 Congress charged the EPA with implementing the RFS Program and
    empowered it with authority to alter the statutory volumes of renewable fuel if the
    EPA finds that the RFS Program is causing severe economic or environmental
    harm or there is an inadequate supply of domestic renewable fuels. The EPA must
    also consult with the Department of Energy (DOE) in exercising this power. See
    42 U.S.C. § 7545(o)(7). The statute further requires “obligated parties,” including
    “refineries, blenders, and importers,” to comply with the RFS Program. 42 U.S.C.
    § 7545(o)(3)(B)(ii).
    Under the EPA’s accompanying regulations, an obligated party must satisfy
    its Renewable Volume Obligation each year by holding sufficient credits, known
    as Renewable Identification Numbers (RINs), at the end of each compliance year.
    A RIN is created when a producer makes a gallon of renewable fuel, blends the
    renewable fuel with petroleum-based fuel, and sells the resulting product
    1
    The RFS Program is codified as Clean Air Act § 211(o), 42 U.S.C.
    § 7545(o)(7).
    -3-
    domestically. 40 C.F.R. § 80.1429. An obligated-party can accumulate RINs to
    meet its RFS Program requirement by: (1) blending renewable fuels into
    petroleum-based fuel and selling the product domestically; or (2) obtaining RINs
    through another source, such as the RIN trading system Congress directed the EPA
    to establish. See 42 U.S.C. § 7545(o)(5). Put simply, the program induces
    refineries to produce renewable fuel products (e.g., ethanol), and if they cannot, to
    purchase biofuel-generated credits from refineries that can.
    B. Small Refinery Exemptions
    Congress was aware the RFS Program might disproportionately impact small
    refineries because of the inherent scale advantages of large refineries and therefore
    created three classes of exemptions to protect these small refineries.
    First, the statute exempted all small refineries from the RFS Program until
    2011. 42 U.S.C. § 7545(o)(9).
    Second, in the meantime, Congress directed DOE to conduct a study “to
    determine whether compliance [with the RFS Program] . . . would impose a
    disproportionate economic hardship on small refineries” after the program’s
    implementation. 42 U.S.C. § 7545(o)(9)(A)(ii)(I). DOE conducted the study in
    2011 and determined that a number of small refineries, including Sinclair’s two
    Wyoming refineries, would suffer “disproportionate economic hardship” if they
    -4-
    were required to comply with the RFS Program. 2 Accordingly, the EPA extended
    the blanket exemption for two more years.
    Third, after the exemption period expired, Congress provided a process for
    small refineries to petition the EPA “at any time” for an extension of the initial
    exemption “for reason of disproportionate economic hardship.” 42 U.S.C.
    § 7545(o)(9)(B)(i). In evaluating these petitions, the EPA must consult with DOE
    and consider the findings of DOE’s study in addition to “other economic factors.”
    42 U.S.C. § 7545(o)(9)(B)(ii).
    This third exemption is at issue in this case.
    C. Sinclair’s Petitions for Small Refinery Exemptions
    Sinclair owns and operates two refineries in Wyoming: one located in
    Sinclair, Wyoming, and another in Casper, Wyoming. Both fall within the RFS
    2
    DOE actually completed its first study in 2009, concluding that no small
    refineries would suffer “disproportionate economic hardship” if they were
    required to comply with the RFS Program. But Congress was unhappy with
    DOE’s methodology and directed the Agency to conduct a new study, requiring it
    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.” See S. Rep. No. 111-45, at 109 (2009), 
    2009 WL 1994747
    .
    DOE completed its second study in 2011, concluding that “[i]f certain small
    refineries must purchase RINs that are far more expensive than those that may be
    generated through blending, this will lead to disproportionate economic hardship
    for those effected entities.” J.A. Vol. 1 at 69 (alteration incorporated).
    -5-
    Program’s definition of “small refinery” and were exempt from the RFS
    requirements until 2011. Those exemptions were extended until 2013 after DOE
    found Sinclair’s Wyoming refineries to be among the 13 of 59 small refineries that
    would continue to face “disproportionate economic hardship” if required to
    comply with the RFS Program.
    Sinclair then petitioned the EPA to extend their small-refinery exemptions,
    arguing that both refineries would continue to suffer “disproportionate economic
    hardship” under the RFS Program. The EPA denied Sinclair’s petitions in two
    separate decisions, finding that both refineries appeared to be profitable enough to
    pay the cost of the RFS Program. Sinclair filed a timely petition for review with
    this court. We grant Sinclair’s petition for review, vacate the EPA’s decisions for
    both of Sinclair’s refineries, and remand for further proceedings consistent with
    this opinion.
    II. Analysis
    We review Sinclair’s petitions under the Administrative Procedure Act
    (APA). The APA requires courts to consider agency action in conformity with the
    agency’s statutory grant of power, and agency action is unlawful if it is “in excess
    of statutory jurisdiction, authority, or limitations, or short of statutory right.” 5
    U.S.C. § 706(2)(C). See generally 
    id. § 706
    (describing additional agency actions
    that reviewing courts can hold unlawful and set aside, including arbitrary and
    capricious rulings).
    -6-
    We review questions of statutory interpretation de novo. EnergySolutions,
    LLC v. Utah, 
    625 F.3d 1261
    , 1271 (10th Cir. 2010).
    A. Judicial Review of Agency Action
    When a court reviews an agency’s legal determination, it generally applies
    the analysis set out by the Supreme Court in Chevron v. Natural Resources Defense
    Council, 
    467 U.S. 837
    (1984). Under Chevron, reviewing courts apply a two-step
    analysis. Chevron step one asks “whether Congress has directly spoken to the
    precise question at issue.” 
    Id. at 842–43.
    If Congress’s intent is clear, then both
    the court and the agency “must give effect to the unambiguously expressed intent
    of Congress.” 
    Id. at 843.
    Courts determine Congress’s intent by employing the
    traditional tools of statutory interpretation, beginning—as always—with an
    examination of the statute’s text. See New Mexico v. Dep’t of Interior, 
    854 F.3d 1207
    , 1223–24 (10th Cir. 2017). But, if Congress has “not directly addressed the
    precise question at issue”—if “the statute is silent or ambiguous with respect to the
    specific issue”—the court must determine at Chevron step two “whether the
    agency’s answer is based on a permissible construction of the statute.” 
    Chevron, 467 U.S. at 843
    –44.
    In some circumstances, however, a court never reaches the Chevron analysis.
    In such cases, we do not need to answer the step one or step two questions. As the
    Supreme Court explained in United States v. Mead Corp., 
    533 U.S. 218
    (2001), the
    initial step of the Chevron inquiry is actually to determine whether Chevron should
    -7-
    apply at all. See Cass R. Sunstein, Chevron Step Zero, 
    92 Va. L
    . Rev. 187, 247
    (2006) (conceptualizing the inquiry of whether Chevron applies as “Chevron step
    zero”); see also Gutierrez-Brizuela v. Lynch, 
    834 F.3d 1142
    , 1157 (10th Cir. 2016)
    (Gorsuch, J., concurring) (discussing the step zero inquiry and the confusion
    created by Mead). 3
    In Mead, the Court held that Chevron applies only where “it appears that
    Congress delegated authority to the agency generally to make rules carrying the
    force of law, and that the agency interpretation claiming deference was
    promulgated in the exercise of that authority.” 
    Mead, 533 U.S. at 226
    –27. This
    context-driven determination requires us to examine the method by which the
    agency exercised its delegated authority. Mead instructs: “It is fair to assume
    generally that Congress contemplates administrative action with the effect of law
    when it provides for a relatively formal administrative procedure tending to foster
    the fairness and deliberation that should underlie a pronouncement of such force.”
    
    Id. at 229–30.
    Mead thus created, in effect, a “safe harbor of Chevron deference”
    3
    We note that neither party discussed the Supreme Court’s decision in City
    of Arlington v. Federal Communications Commission, 
    133 S. Ct. 1863
    (2013), in
    their supplemental briefs. We have not previously addressed the effect—if
    any—City of Arlington might have on our application of the Mead inquiry. But
    we do note that Justice Scalia, writing for the majority in City of Arlington,
    reaffirmed that courts must determine whether Chevron or Mead controls at step
    zero. 
    See 133 S. Ct. at 1874
    (“The dissent is correct that United States v. Mead
    requires that, for Chevron deference to apply, the agency must have received
    congressional authority to determine the particular matter at issue in the particular
    manner adopted. No one disputes that.” (emphasis added)).
    -8-
    for agency interpretations produced via formal agency action—formal rulemaking
    or adjudication—and those produced via informal notice-and-comment rulemaking.
    Charles H. Koch, Jr. & Richard Murphy, 3 Admin. L. & Prac. § 10:12 (Feb. 2017
    update); see also Richard J. Pierce, Jr., Administrative Law Treatise, § 3.5 (2010)
    (“After Mead, it is possible to know only that legislative rules and formal
    adjudications are always entitled to Chevron deference, while less formal
    pronouncements like interpretative rules and informal adjudications may or may not
    be entitled to Chevron deference.”).
    In situations where Chevron does not apply, Mead requires us to examine the
    persuasiveness of agency action with no thumb on the scale of judicial deference.
    As Mead explained, we follow the analysis set forth in Skidmore v. Swift & Co.,
    
    323 U.S. 134
    (1944). In that case, the Court explained that the weight courts
    provide an administrative judgment “will depend upon the thoroughness evident in
    [the agency’s] 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.” 
    Id. at 140.
    Following Mead, the Court examined agency action that was less formal than
    notice-and-comment rulemaking when it reviewed an opinion letter issued by the
    Social Security Administration. See Barnhart v. Walton, 
    535 U.S. 212
    , 221–22
    (2002). It found that such informal agency action “does not automatically deprive
    that interpretation of the judicial deference otherwise its due,” but rather, whether
    -9-
    courts provide Chevron deference “depends in significant part upon the interpretive
    method used and the nature of the question at issue.” 
    Id. The factors
    the Court
    considered included the interstitial nature of the legal question, the related
    expertise of the agency, the importance of the question to administration of the
    statute, the complexity of that administration, and the careful consideration the
    agency had given the question over a long period of time. 
    Id. at 222.
    The question we must answer, then, is whether to apply Chevron or Skidmore
    deference to the EPA’s use of informal adjudications to resolve Sinclair’s petitions.
    See WildEarth Guardians v. Nat’l Park Serv., 
    703 F.3d 1178
    , 1188 (10th Cir.
    2013). Sinclair argues that we should review the EPA’s decisions using only
    Skidmore deference, but maintains it would still prevail under a more deferential
    Chevron review. Aplt. Supp. Br. at 1–2. The EPA, of course, argues the opposite.
    As a preliminary matter, we acknowledge that the EPA’s decisions resolving
    Sinclair’s hardship petitions were conducted via informal adjudication (the same
    procedure employed by the U.S. Customs Service in Mead). The parties do not
    seriously contest this conclusion. The decisions were adjudications because they
    were specific to the parties at issue—in fact, they were specific even to the
    individual refineries at issue (the EPA produced separate decisions for the Sinclair,
    Wyoming and Casper, Wyoming refineries)—and were resolving petitions for
    Sinclair’s exemptions from the RFS Program. The decisions were also informal
    because they were resolved on the basis of Sinclair’s submissions and involved no
    -10-
    oral argument, opportunity for cross-examination, or other “trial-like” procedures
    generally required by the APA. See 
    Pierce, supra
    , at Vol. 1 § 8.2 (describing the
    trial-like procedures the APA requires for formal adjudications); see also J.A. Vol.
    1 at 31 (the Casper, Wyoming refinery opinion describing Sinclair’s submission).
    Under Mead, we conclude that Skidmore deference applies to the EPA’s
    decision here. First of all, Congress specifically authorized the EPA to promulgate
    regulations on aspects of the RFS Program, but not for the small refinery
    exemptions. This means the agency did not have the benefit of notice-and-
    comment about its interpretation of the term “disproportionate economic hardship.”
    See, e.g., 42 U.S.C. § 7545(o)(2)(A)(i) (requiring the EPA to promulgate
    regulations to “ensure that gasoline sold or introduced into commerce in the United
    States . . . contains the applicable volume of renewable fuel”). Instead, the EPA
    conducted its interpretation via informal adjudication. And the fact that the
    adjudication was informal is also important—Sinclair’s involvement in the
    decision-making was limited to submitting petitions and the EPA did not have the
    benefit of hearing expert testimony on the topic. See 
    Pierce, supra
    , at Vol. 1 § 8.2
    (describing the trial-like procedures required for formal adjudications).
    Additionally, the decisions were not made by the head of the EPA but instead
    by a mid-level Agency official. See Aplt. Supp. Br. at 7–8; see also, e.g., Groff v.
    United States, 
    493 F.3d 1343
    , 1352 (Fed. Cir. 2000) (one factor in the court’s
    conclusion that it should provide Chevron deference to the agency action was that
    -11-
    the adjudication at issue was “formal and culminate[d] in a formal written decision
    by the head of the agency, not a nonbinding disposition by a low-level agency
    official”).
    Next, the decisions hold no precedential value for third parties. Indeed, the
    decisions have no precedential value even for the refiner, since each petition must
    be resolved on a case-by-case basis (again, the EPA produced two decisions, one
    for each of Sinclair’s refineries). Nor do third parties have access to the decisions,
    since the EPA does not publicly release its decisions because they contain
    confidential business information. Aple. Supp. Br. at 8.
    Finally, the EPA’s viability analysis is not a longstanding practice, but is,
    instead, only a few years old. 4
    Thus, Mead and Barnhart compel our conclusion that Congress did not
    intend the EPA’s interpretation of “disproportionate economic hardship” to have
    the “force of law.” We therefore apply Skidmore deference in reviewing the EPA’s
    interpretation.
    B. The “Disproportionate Economic Hardship” Exemption
    In analyzing Congress’s grant of power to the EPA to administer the RFS
    Program, we begin, as always, with the statutory text. “Unless otherwise defined,
    4
    Although the record does not indicate exactly how long the EPA’s
    interpretation of “disproportionate economic hardship” has been in place, as a
    matter of logic, the EPA’s interpretation must have been derived in 2011 at the
    earliest (the year that DOE released its second study).
    -12-
    statutory terms are generally interpreted in accordance with their ordinary
    meaning.” BP Am. Prod. Co. v. Burton, 
    549 U.S. 84
    , 91 (2006); see also Engine
    Mfrs. Ass’n v. S. Coast Air Quality Mgmt. Dist., 
    541 U.S. 246
    , 252 (2004)
    (“Statutory construction must begin with the language employed by Congress and
    the assumption that the ordinary meaning of that language accurately expresses the
    legislative purpose.”).
    1. The Statutory Requirement
    As previously mentioned, Congress provided that small refineries could
    petition the EPA to extend their initial exemption from the RFS Program “for
    reason of disproportionate economic hardship.” 42 U.S.C. § 7545(o)(9)(B)(i). The
    relevant statutory provision reads in full:
    (B) Petitions based on disproportionate economic
    hardship
    (i) Extension of exemption
    A small refinery may at any time petition the [EPA]
    Administrator for an extension of the exemption
    under subparagraph (A) for the reason of
    disproportionate economic hardship.
    (ii) Evaluation of petitions
    In evaluating a petition under clause (i), the [EPA]
    Administrator, in consultation with the Secretary of
    Energy, shall consider the findings of the study under
    subparagraph (A)(ii) and other economic factors.
    42 U.S.C. § 7545(o)(9) (emphasis added).
    -13-
    Although Congress did not define the term “disproportionate economic
    hardship” in the statute, the provision makes clear that Congress provided the EPA
    with a comprehensive directive in analyzing and evaluating RFS Program
    exemptions. The statute prescribes the overall process: (1) when petitions can be
    made: “at any time”; (2) the relevant agency actors: the EPA must make decisions
    in “consultation with” DOE; (3) the relevant question: whether a refinery will
    suffer “disproportionate economic hardship” if it is required to participate in the
    RFS Program for a given year; and (4) the methodology the agency is to use: the
    EPA must consider the findings of DOE’s 2011 study and “other economic
    factors.” 42 U.S.C. § 7545(o)(9)(B).
    With this statutory background, we turn to whether the EPA’s decisions
    comport with Congress’s directive to grant exemptions when a small refinery
    demonstrates that complying with the RFS Program would cause it to suffer a
    “disproportionate economic hardship.”
    2. The EPA’s Decisions
    Prior to considering a refinery’s petition for a hardship exemption, the EPA
    receives a recommendation on the petition from DOE. In its 2011 study, DOE
    created a scoring matrix for determining its recommendations for granting
    exemptions. The first part of the matrix assesses the “disproportionate structural
    and economic” impacts of the RFS Program on the refinery, looking both at (1)
    “disproportionate structural impact metrics” (a refinery’s percentage of diesel
    -14-
    production, access to credit, local market acceptance of renewable fuels, etc.) and
    (2) “disproportionate economic impact metrics” (the firm’s relative refining
    margin, the degree to which the refiner can blend renewable fuels, whether RINs
    are a net source of revenue, etc.). J.A. Vol. 1 at 99–102 (DOE’s 2011 Small
    Refinery Exemption Study).
    The second part of DOE’s matrix assigns scores for three “viability metrics”:
    “(1) whether the cost of compliance ‘would reduce the profitability of the firm
    enough to impair future efficiency improvements;’ (2) whether ‘individual special
    events’ have had ‘a temporary negative impact on the ability of the refinery to
    comply;’ and (3) whether compliance costs are ‘likely to lead to shutdown’ of the
    refinery.” Aplt. Br. at 13–14 (quoting J.A. Vol. 1 at 103–04).
    DOE’s interpretation of its methodology does not require that the cost of
    compliance threaten a refinery’s long-term viability. Instead, DOE recommends a
    50 percent waiver if the ranking meets a certain threshold on either side of the
    matrix, although the DOE previously required the ranking meet certain thresholds
    on both sides of the matrix. J.A. Vol. 1 at 17. DOE’s scoring change “is due to
    language included in an explanatory statement accompanying the 2016
    Consolidated Appropriations Act,” which instructed the DOE as follows: “‘If the
    Secretary finds that either of these two components exists, the Secretary is directed
    to recommend to the EPA Administrator a 50 percent waiver of RFS requirements
    -15-
    for the petitioner.’” 
    Id. (quoting Consolidated
    Appropriations Act, 2016, Pub. L.
    No. 114-113 (2015)).
    Here, DOE applied its matrix methodology and recommended the EPA
    provide a 50 percent waiver of the RFS Program’s requirements for both of
    Sinclair’s refineries. See J.A. Vol. I at 15–17 (Sinclair, Wyoming refinery
    decision); J.A. Vol. I at 35–37 (Casper, Wyoming refinery decision).
    The EPA rejected DOE’s recommendations and denied both petitions.
    In denying Sinclair’s exemption for the Sinclair, Wyoming refinery, the EPA
    explained its view that “disproportionate economic hardship” requires a threat to
    the “longer term prospects” of a refinery:
    EPA believes viability continues to be an important
    economic factor for determining “disproportionate
    economic hardship.” . . . . We consider whether [the
    Sinclair, Wyoming refinery] will remain a competitive and
    profitable refinery while satisfying its RFS obligations.
    EPA notes that it considers profitability not merely in the
    context of a single year’s financial statements, but also in
    the context of assessing the longer term prospects for the
    refinery. EPA also evaluates viability using metrics
    considered by DOE in its viability index: (a) compliance
    costs eliminate efficiency gains (impairment); (b) individual
    special events; and (c) compliance costs likely to lead to
    shut down. In reaching our conclusion, we consider all of
    this information on viability, and additional relevant
    information as available, to determine whether [the Sinclair,
    Wyoming refinery] faces a “disproportionate economic
    hardship” from compliance, and not merely an economic
    impact.

    J.A. Vol. 1 at 18–19 (quoting DOE 2011 Small Refinery Study) (citations omitted)
    (emphasis added in first sentence); see also 
    id. at 38–39
    (EPA’s identical analysis
    in its denial of Sinclair’s petition for the Casper, Wyoming refinery).
    In applying this long-term viability interpretation, the EPA rejected DOE’s
    matrix scores for both Sinclair refineries. The EPA concluded that “viability”
    meant only that program costs threatened the “long-term” survival of the refinery,
    not a short-term comparison to other industry actors:
    In the discussion that follows, EPA independently reviews
    the information as we consider other economic factors in our
    analysis, including, but not limited to, profitability, net
    income, cash flow and cash balances, gross and net refining
    margins, ability to pay for refinery improvement projects,
    corporate structure, debt and other financial obligations,
    RIN prices, and the cost of compliance through RIN
    purchases. After considering all of this information, EPA
    finds [the Sinclair, Wyoming refinery] will not experience
    “disproportionate economic hardship” from compliance with
    the RFS program.
    As an initial matter, EPA recognizes its decision differs from
    DOE’s recommendation. The CAA requires that EPA act on
    a small refinery’s petition “in consultation with” DOE,
    “consider[ing] the findings of” the DOE Small Refinery
    Study and “other economic factors.” EPA gives weight to
    DOE’s technical evaluation and scoring of the refinery,
    recognizing that DOE has more experience in assessing,
    e.g., the impact of a particular special event, and how to
    balance short-term events with longer term planning and
    concerns over viability. However, EPA has responsibility
    for making the ultimate decision after considering DOE’s
    evaluation and recommendation, and continues to believe
    that the proper interpretation of the statutory
    prerequisite—disproportionate economic hardship—involves
    “examining the impact of compliance costs on a refinery’s
    -17-
    ability to maintain profitability and competitiveness—i.e.
    viability—in the long term.”
    J.A. Vol. 1 at 17–18 (quoting CAA section 211(o)(9)(B)(ii) and, in last sentence,
    Hermes Consol., LLC v. EPA, 
    787 F.3d 568
    , 575 (D.C. Cir. 2015)) (emphasis
    added).
    Thus, according to the EPA, to show “disproportionate economic hardship” a
    small refinery must demonstrate an existential threat: it “faces RFS compliance
    costs that would ‘significantly impact the operation of the firm, leading eventually
    to an inability to increase efficiency to remain competitive, eventually resulting in
    closure.’” 5 J.A. Vol. 1 at 19–20 (quoting DOE Small Refinery Study) (emphasis
    added); see also 
    id. at 39–40
    (EPA’s identical analysis in its denial of Sinclair’s
    petition for the Casper, Wyoming refinery).

    The dissent describes this sentence as “regrettably inartful,” claiming that
    the EPA did not mean what it said, but rather applied DOE’s viability metrics in a
    “nuanced analysis.” Diss. at 1. But, as we have shown above, we do not read this
    sentence in isolation. And, in any event, the EPA repeats this language in its
    advocacy before us, using it to describe the test it applied in resolving Sinclair’s
    petitions.
    “Viability” is a term of art for purposes of EPA’s
    assessment of petitions for small refinery
    exemptions. . . . EPA has also described this factor as
    requiring a small refinery to “show that it faces RFS
    compliance costs that would ‘significantly impact the
    operation of the firm, leading eventually to an inability
    to increase efficiency to remain competitive, eventually
    resulting in closure.’”
    Aple. Br. at 40 n.11 (internal citations omitted) (emphasis added).
    -18-
    As we discuss next, the EPA’s long-term threat of closure requirement is
    inconsistent with the plain meaning of “disproportionate economic hardship.”
    3. The Plain Meaning of “Disproportionate Economic Hardship”
    Sinclair claims the EPA’s position is that “no matter how disproportionate
    the economic impact of the RFS Program on other refineries, there can be no
    ‘disproportionate economic hardship’ unless compliance with the RFS Program is
    so costly that it will eventually force a small refinery to shut down,” and argues
    that this position is contrary to the plain language of the term “disproportionate
    economic hardship.” Aplt. Br. at 34. Sinclair also maintains that the EPA’s
    “viability” test not only fails the agency’s statutory duty to compare the refinery at
    issue with its competitors, but also requires significantly more “hardship” to the
    refinery than the statute instructs. 6
    The statutory text at issue allows a range of linguistic possibilities in
    defining “disproportionate economic hardship.” But as we discuss below, the
    EPA’s interpretation falls outside the boundaries of permissible choice. It chose a
    6
    We reject the EPA’s argument that Sinclair “waived” its statutory
    interpretation argument by failing to raise it during the administrative
    proceedings. See Aple. Br. at 32–33. Sinclair fully explained its understanding
    of the statutory term as informed by DOE’s exemption study and recommendation
    that Sinclair was eligible for a 50 percent exemption. And, in any event, statutory
    interpretation is the specialization of the courts, not the agencies. See Frontier
    Airlines, Inc. v. Civil Aeronautics Bd., 
    621 F.2d 369
    , 371 (10th Cir. 1980) (“The
    general rule requiring exhaustion of remedies before an administrative agency is
    subject to an exception where the question is solely one of statutory
    interpretation.”).
    -19-
    definition of economic hardship plainly at odds with Congress’s statutory command
    by reading a “viability” requirement into the statute and the “disproportionate”
    requirement out of it.
    We first evaluate Sinclair’s argument that the EPA improperly imported a
    condition of future long-term viability into the statutory language. This question is
    hardly in dispute, because the EPA admits as much. The EPA concluded its
    decision for the Sinclair, Wyoming refinery with the following statement:
    EPA does not doubt that Sinclair incurred costs, both
    planned and unplanned, which affected profitability.
    However, as discussed above, EPA believes that it is
    necessary to show that RFS compliance will have an impact
    on the refinery’s ongoing future viability to be eligible for
    an exemption. After considering the full financial picture of
    [the Sinclair, Wyoming refinery] for 2014 and prior years,
    EPA does not find that compliance with RFS for 2014 would
    threaten [the Sinclair refinery]’s viability. Given [the
    Sinclair refinery]’s situation, we do not believe that an RFS
    exemption for [the Sinclair refinery] is justified under the
    statutory requirement of a disproportionate economic
    hardship.
    J.A. Vol. 1 at 20–21 (emphasis added); see also 
    id. at 39–40
    (similar language in
    the Casper, Wyoming refinery opinion).
    The EPA’s use of the word “necessary” proves Sinclair’s point. If long-term
    “viability” was merely one element the EPA considered in its “disproportionate
    economic hardship” analysis, that would be a different story. But by stating that
    future viability (meaning whether the firm will go out of business) is necessary
    -20-
    to—in effect, the sine qua non of—its decision, the EPA demonstrates it will not
    grant an exemption unless there is a threat to a refinery’s long-term viability.
    The EPA’s interpretation takes the statutory language too far. First, as a
    matter of textual exegesis, a “‘hardship’” is something that “makes one’s life hard
    or difficult—not just something that makes continued existence impossible.” Aplt.
    Br. at 35; see Oxford English Dictionary (2017) (defining “hardship” as
    “[s]omething which is hard to bear”); Black’s Law Dictionary (10th ed. 2014)
    (defining “hardship” as “[p]rivation; suffering or adversity”); Webster’s Third New
    Int’l Dictionary 1033 (1971) (defining “hardship” as “something that causes or
    entails suffering or privation”).
    “[V]iability,” on the other hand, is the “ability to continue or be continued;
    the state of being financially sustainable.” Oxford English Dictionary (2017); see
    also Webster’s Third New Int’l Dictionary 2548 (1971) (defining “viability” as “the
    quality or state of being viable,” and defining “viable,” in turn, as “capable of
    living”). As a matter of common sense, an experience that causes hardship is less
    burdensome than an experience that threatens one’s very existence. Our law clerks,
    for example, might say their first year of law school was a “hardship” they
    suffered, but they could hardly claim that the experience of learning the law
    threatened their very “viability” (we hope).
    The EPA argues that “viability” and “hardship” are the same, since
    “hardship” can be defined as “suffering” and “privation.” Aple. Br. at 38. But as
    -21-
    we just explained, “suffering” and “privation” may be difficult to bear, but they do
    not necessarily rise to the level of threatening one’s very existence. And the EPA’s
    interpretation of “viability” is akin to a death knell, not simple privation. In any
    event, DOE’s matrix analysis supplied three “viability metrics” that collectively
    determine hardship: (1) reduced profitability; (2) temporary negative events; and
    (3) risk of closure. See J.A. Vol. 1 at 103. The EPA’s interpretation ignores two-
    thirds of this analysis and selects only risk of closure as the appropriate measure of
    hardship. This is not a reasonable interpretation of the statutory term. In short, the
    EPA’s equation of “hardship” and “viability” improperly transforms Congress’s
    statutory text into something far beyond what Congress plausibly intended.
    The statute also commands the EPA to consider the disproportionate impact
    of the RFS Program, which inherently requires a comparative evaluation. The EPA
    must compare the effect of the RFS Program compliance costs on a given refinery
    with the economic state of other refineries. The EPA’s viability test involves no
    such comparison, but instead looks at each refinery in isolation and asks whether
    the cost of long-term compliance with the RFS Program would force the refinery to
    shut down. By making long-term viability a necessary factor in its analysis, the
    EPA impermissibly reads the word “disproportionate” out of the statute. See Clark
    v. Rameker, 
    134 S. Ct. 2242
    , 2248 (2014) (“a statute should be construed so that
    effect is given to all its provisions, so that no part will be inoperative or
    superfluous”). The EPA tries to sidestep the comparative nature of the
    -22-
    “disproportionate economic hardship” by pointing out that the statute requires the
    EPA to consider DOE’s study and “other economic factors.” Because viability is
    one of the factors considered by DOE, the EPA argues it is also an appropriate
    consideration for the EPA. See Reply Br. at 11. But as we explained above, the
    statutory requirements for what sources the EPA must consider in evaluating the
    petitions are distinct from the overall purpose of the inquiry. In effect, the EPA
    takes the holistic evaluation required by Congress and morphs it into a single
    question: a threat of closure inquiry.
    The EPA’s narrow viability evaluation is also not supported by contextual
    clues in the statutory scheme. Congress, in fact, directed the EPA to apply a
    closure test for another part of the CAA involving primary nonferrous smelter
    orders. 42 U.S.C. § 7419(d)(2) (requirement to use continuous emission reduction
    technology can be waived “upon a showing by the owner or operator of the smelter
    that such requirement would be so costly as to necessitate permanent or prolonged
    temporary cessation of operations of the smelter.” (emphasis added)). Although
    this CAA provision is not part of the RFS Program, it makes the basic point that
    Congress knows how to supply a closure test when it intends to do so. See Antonin
    Scalia & Bryan A. Garner, Reading Law: The Interpretation of Legal Texts 170–73
    (2012) (discussing the presumption of consistent usage).
    The EPA places significant weight on two recent circuit court decisions
    addressing § 7545(o)(9)(B)(ii), which it claims support its interpretation of the
    -23-
    statute: Hermes Consolidated, LLC v. EPA, 
    787 F.3d 568
    (D.C. Cir. 2015) and Lion
    Oil Company v. EPA, 
    792 F.3d 978
    (8th Cir. 2015). In Hermes, a refinery
    challenged the EPA’s denial of its extension for an economic hardship exemption
    from the RFS Program (a denial supported by DOE’s matrix scheme). The court
    rejected the refinery’s challenge under Chevron step one, concluding that the
    EPA’s reliance on a viability index did not contradict the plain language of
    § 7545(o)(9)(B) because so long as “EPA consults with DOE and considers the
    2011 Study and ‘other economic factors,’ EPA retains substantial discretion to
    decide how to evaluate hardship petitions.” 
    Hermes, 787 F.3d at 574
    –75 (internal
    citation omitted). The D.C. Circuit also rejected the refinery’s Chevron step two
    argument, concluding that the EPA’s method of evaluating “‘disproportionate
    economic hardship’ is ‘based on a permissible construction of the statute.’” 
    Id. at 575
    (quoting 
    Chevron, 467 U.S. at 843
    ). In other words, the court found it
    reasonable for the EPA to incorporate the methodology from the 2011 DOE study,
    and the viability matrix in particular, because the statute requires the EPA to
    consider the findings of the study and “other economic factors” in evaluating
    hardship petitions. Thus, the court concluded the EPA’s choice was within its
    discretion under Chevron step two. See 
    id. In Lion
    Oil, the Eighth Circuit also rejected the refinery’s Chevron step one
    argument. The court stated that since the statute does not define “disproportionate
    economic hardship,” and Congress delegated authority to the agency to implement
    -24-
    an ambiguous statute, the court was “‘required to accept the agency’s statutory
    interpretation, so long as it is 
    reasonable.’” 792 F.3d at 984
    (quoting Fast v.
    Applebee’s Int’l, Inc., 
    638 F.3d 872
    , 876 (8th Cir. 2011). The Eighth Circuit
    concluded that the EPA’s choice to measure “hardship” by examining the refinery’s
    viability in the long run was within the agency’s discretion, and was thus
    reasonable. 
    Id. But these
    cases are distinguishable. As an initial matter, neither the D.C.
    Circuit nor the Eighth Circuit considered whether Mead should control its
    interpretation of the statute; instead, both courts assumed that Chevron applied.
    Regardless, as we explained above, Mead instructs us that Skidmore deference is
    the appropriate standard of review to apply to an informal adjudication that does
    not carry “the force of law.”
    The petitioner in Hermes argued that mere “[c]onsideration of a viability
    index” was “inconsistent with [the EPA’s] statutory 
    mandate.” 787 F.3d at 574
    . In
    other words, the EPA could not consider a refinery’s viability at all, even if
    viability was considered along with a host of other economic factors. The D.C.
    Circuit properly rejected that argument. The statutory scheme does not prohibit the
    EPA from considering viability as a factor. But as we explained above, when the
    EPA makes long-term viability the necessary, if not the sole, factor—refusing to
    grant an exemption unless there is a threat to a refinery’s long-term viability—it
    renders an interpretation outside the bounds of permissible statutory choice.
    -25-
    As for Lion Oil, the Eighth Circuit’s decision does not make clear whether
    the petitioner argued it was impermissible for the EPA to consider viability as a
    factor in its analysis (as in Hermes) or as the sole factor in its analysis (as in this
    case). 
    See 792 F.3d at 984
    . Either way, we are unpersuaded. If the former, our
    analysis of Hermes applies. If the latter, Lion Oil improperly interpreted Hermes as
    rejecting the EPA’s use of viability as the sole factor in its “disproportionate
    economic hardship” analysis before relying entirely on the D.C. Circuit’s
    reasoning. See 
    id. Consequently, we
    are unpersuaded by the court’s analysis in
    Lion Oil.
    Mead instructs us to defer to agency interpretations of a statute only to the
    extent those decisions have the “power to 
    persuade.” 533 U.S. at 220
    . Since our
    textual and contextual analyses demonstrate that the EPA’s interpretation of
    § 7545(o)(9)(B) is contrary to the meaning and purpose of the statute, the EPA has
    failed to persuade us here.
    III. Conclusion
    By reading a necessary “viability” requirement into its statutory directive to
    evaluate a refinery’s petition for exemption from the RFS program based on
    “disproportionate economic hardship,” the EPA exceeded its statutory authority.
    We therefore GRANT Sinclair’s petition for review, VACATE the EPA’s decisions
    for Sinclair’s two Wyoming refineries, and REMAND for further proceedings
    consistent with this opinion.
