    EDITH H. JONES, Circuit Judge:
    Through       notice-and-comment          rulemaking,        the    Environmental
    Protection Agency (“EPA”) reviewed and decided to revise 1 the earliest
    1The original rule was titled: “Effluent Limitations Guidelines and Standards for the
    Steam Electric Power Generating Point Source Category,” 80 Fed. Reg. 67838 (Nov. 3, 2015)
    (the “2015 Rule”). The revision, which is the subject of this case, is titled: Postponement of
    Certain Compliance Dates for the Effluent Limitations Guidelines and Standards for the
    Steam Electric Power Generating Point Source Category, 82 Fed. Reg. 43,494 (Sept. 18, 2017)
    (the “Postponement Rule”).

    No. 18-60079
    compliance dates for new, stringent BAT (“best available technology
    economically achievable”) effluent limitations and PSES (“pretreatment
    standards for existing source”) concerning two waste streams from steam
    electric power generating point sources that had previously been promulgated
    in a 2015 Rule.
    More specifically, the agency postponed for two years only the earliest
    compliance dates mandated by the 2015 Rule for flue gas desulfurization
    (FGD) wastewater and bottom ash transport water, while (a) retaining the
    2015 Rule’s BAT limitations and pretreatment standards for other waste
    streams from such power plants, and (b) not altering either the last date for
    compliance (December 2023) or, pending reconsideration, the substantive
    limits required by the 2015 Rule for the two postponed stream modifications.
    A consortium of environmental groups has challenged the postponement, while
    EPA and the intervenor, Utility Water Act Group (“UWAG”), 2 defend the
    Postponement Rule. We conclude that the EPA had statutory authority to pass
    this tailored rule, the agency explained its decision adequately, its decision was
    reasonable, and it was thus neither arbitrary nor capricious. The petition for
    review is DENIED.
    BACKGROUND
    The 2015 Rule represented the culmination of ten years’ work by EPA to
    update steam electric power generating plant standards for compliance with
    the Clean Water Act, 33 U.S.C. § 1251 et seq., that had been in place since
    1982.       In that Rule, the agency, among other things, defined much more
    stringent BAT limits and pretreatment standards for seven defined
    wastestreams. Recognizing that power plants would need substantial lead
    UWAG is an ad hoc voluntary group of 145 individual energy companies and three
    2
    national energy trade associations.

    No. 18-60079
    time to plan, fund, and build necessary new facilities, the agency mandated in
    the 2015 Rule an earliest compliance date of November 2018 and delegated to
    permitting authorities the flexibility to approve individual point source
    compliance as feasible over a period extending until the end of 2023.
    Four lawsuits challenging the 2015 Rule were soon filed in the federal
    courts. 3 The petitions were consolidated by the Judicial Panel on Multidistrict
    Litigation and transferred to this court. 4 During these preliminaries, UWAG,
    later supplemented by the Small Business Administration’s Office of Advocacy,
    submitted petitions asking EPA to reconsider the entire 2015 Rule and
    suspend its approaching deadlines. 5               Among other things, these petitions
    raised substantial questions, based on newly discovered information, about the
    extraordinary costs of implementing the 2015 Rule and the infeasibility of
    EPA’s proposed technology as applied to certain power plants. Taking these
    petitions seriously, EPA’s Administrator determined that it was appropriate
    and in the public interest to reconsider the 2015 Rule.
    After an initial stay, a formal rulemaking procedure ensued, the notice
    of which generated thousands of written comments, and the agency conducted
    a public hearing on July 31, 2017. In the end, EPA decided to adhere to most
    aspects of the 2015 Rule. EPA left in place the legacy wastewater limitations,
    which are BAT limitations that apply to each of the regulated wastestreams

    beginning on the effective dates set out in the 2015 Rule; the new and more
    stringent limitations and quantitative standards (i.e., the permissible amount
    of discharges); and the latest compliance date for NPDES permitting
    authorities to impose those limitations. 6 See generally, Postponement Rule,
    82 Fed. Reg. at 43,494. But the agency also decided it must reconsider the
    2015 Rule’s regulations governing two wastestreams (FGD wastewater and
    bottom ash transport water) in light of “new information not contained in the
    record for the 2015 Rule.” 
    Id. at 43,496.
    As support for reconsideration, EPA
    cited “the inherent discretion the Agency has to reconsider past policy decisions
    consistent with the CWA and other applicable law.” 
    Id. EPA’s expressed
    purpose for postponing the earliest effective compliance dates for these
    wastestreams during reconsideration was to “prevent the potentially needless
    expenditure of resources during a rulemaking that may ultimately change the
    2015 Rule . . . .” 
    Id. The agency,
    however, specifically declined to forecast
    whether, after reconsideration, it will substantially revise the 2015 Rule. 7
    STANDARD OF REVIEW
    The standard of review here is deferential, focusing on whether the
    agency action is “arbitrary, capricious, an abuse of discretion, or otherwise not
    in accordance with law.” 5 U.S.C. § 706(2)(A). “If the agency’s reasons and
    policy choices conform to minimal standards of rationality, then its actions are
    reasonable and must be upheld.” Tex. Oil & Gas Ass’n v. EPA, 
    161 F.3d 923
    ,
    6 The Postponement Rule extended the “as soon as possible” date for these two effluent
    limitations by two years, from November 1, 2018 until November 1, 2020. Postponement
    Rule, 82 Fed. Reg. at 43,496. The Postponement Rule did not modify the “no later than” date
    of December 31, 2023, since EPA had no reason to believe that date was driving compliance
    costs. 
    Id. at 43,496.
    7At oral argument, the court was informed that, in response to the uncertainty
    pending reconsideration, permitting authorities may continue to require compliance with the
    2015 Rule as to these wastestreams while extending the deadlines.

    , 824 (1971).
    EPA must provide a reasoned explanation for its revisions and follow the
    same process to revise a rule as it used to promulgate it. See Perez v. Mortg.
    Bankers Ass’n, 
    135 S. Ct. 1199
    , 1206 (2015). Even “a decision based on an
    administrative record of less than ideal clarity will be upheld if the agency’s
    path may reasonably be discerned.” United States v. Garner, 
    767 F.2d 104
    , 118
    (5th Cir. 1985). This court, however, “‘may not supply a reasoned basis for the
    agency’s action that the agency itself has not given.’” Motor Vehicle Mfrs. Ass'n

    DISCUSSION
    In this instance, EPA went out of its way to issue a narrow
    reconsideration decision, leaving intact the bulk of the 2015 Rule, and to
    substantiate its course of action legally through notice-and-comment
    rulemaking. 8 According to the Petitioners, that was not enough. Petitioners
    fault the EPA for issuing the Postponement Rule without legal authority
    because they argue it is an unauthorized stay or the “functional equivalent” of
    a stay of the 2015 Rule; for failing to consider mandatory statutory factors
    before promulgating a revision; and for failing to comply with what they take
    to be a three-year ELG compliance deadline in the CWA. We address each of
    8 EPA’s earlier stay applied to five wastestreams, since the EPA was considering
    revising compliance dates for the limitations and standards for all of them. See EPA,
    Postponement of Certain Compliance Dates for Effluent Limitations Guidelines and
    Standards for the Steam Electric Power Generating Point Source Category, 82 Fed. Reg.
    19,005 (Apr. 25, 2017). Reflecting EPA’s thoughtful and narrow decision, the Postponement
    Rule challenged here applies only to the FGD and ash transport water ELGs since the EPA
    ceased reconsidering the limitations and standards applicable to the other wastestreams.

    No. 18-60079
    these arguments in turn.
    A. Whether the Postponement Rule effects a “stay” or its
    “functional equivalent” concerning the 2015 Rule.
    Petitioners do not challenge EPA’s statutory authority to revise the 2015
    Rule’s ELGs because the CWA explicitly authorizes EPA to revise previously-
    promulgated rules.          See 33 U.S.C. §§ 1311(d), 1314(b), (g)(1), (m)(1)(A),
    1317(b)(2).    Instead, they contend that the Postponement Rule was not a
    revision, but either a stay or the functional equivalent of a stay of the earlier
    Rule.
    The Postponement Rule is not a stay. In so characterizing it, Petitioners
    misstate the agency’s position and rely on inapposite legal authority. 9 EPA
    has consistently justified the Postponement Rule as a revision under both its
    inherent authority to reconsider past decisions and as an action authorized
    under the Clean Water Act. See Postponement Rule, 82 Fed. Reg. at 43,496
    (“Agencies have inherent authority to reconsider past decisions and to revise,
    replace or repeal a decision to the extent permitted by law and supported by a
    reasoned explanation . . . Particularly relevant here, the CWA expressly
    authorizes EPA to revise effluent limitations and standards.”) (citations
    omitted). Petitioners chiefly cite cases discussing administrative stays under
    the APA. But, as they admit, although EPA’s earlier stay relied on Section 705
    Of course, EPA may not offer post-hoc rationales justifying its decision, and so careful
    9
    attention must be paid to the express rationale offered in the rulemaking. Motor Vehicle
    Mfrs. 
    Ass'n, 463 U.S. at 50
    , 103 S. Ct. at 2870. But Petitioners offer only snippets of EPA
    language taken out of context to imply that EPA did not consider the Postponement Rule to
    be a revision of the 2015 Rule. See, e.g., Postponement Rule, 82 Fed. Reg. at 43,496 (“EPA
    has decided to undertake a new rulemaking, which may result in substantive changes to the
    2015 Rule”); see also 
    id. at 43,497
    (stating that in “the next rulemaking,” EPA would consider
    issues raised by petitions for reconsideration of the ELG Rule, “in conjunction with the
    statutory factors for determining BAT for these waste streams”); 
    id. at 43,498
    (EPA
    indicating that it “anticipates that [its] next rulemaking will necessarily address compliance
    dates in some fashion.”).

    No. 18-60079
    of the APA, EPA did not cite the APA as authorizing this Postponement Rule.
    EPA at all times claimed to be revising the prior rule. Consequently, cases like
    Clean Air Council v. Pruitt, 
    862 F.3d 1
    , 9 (D.C. Cir. 2017) and Air Alliance
    Houston v. EPA, 
    906 F.3d 1049
    (D.C. Cir. 2018) (per curiam), cited by
    Petitioners, are inapposite because they interpreted the stay provision in the
    Clean Air Act and the APA, neither of which is germane to this case. 10
    EPA correctly surmised that, in addition to its statutory authority to
    revise rules under the CWA, administrative agencies possess the inherent
    authority to revise previously-promulgated rules, so long as they follow the
    proper administrative requirements and provide a reasoned basis for the
    agency decision. See FCC v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 515,
    129 S. Ct., 1800, 1811 (2009) (recognizing that the Administrative Procedure
    Act “makes no distinction . . . between initial agency action and subsequent
    agency action undoing or revising that action”); Motor Vehicle Mfrs. 
    Ass’n, 463 U.S. at 42
    , 103 S Ct. at 2866 (“[W]e fully recognize that ‘regulatory
    agencies do not establish rules of conduct to last forever,’ and that an agency
    must be given ample latitude to ‘adapt their rules and policies to the demands
    of changing circumstances.’”) (citation omitted); 
    Perez, 135 S. Ct. at 1206
    (agencies may amend rules provided that they “use the same procedures when
    they amend . . . a rule as they used to issue the rule in the first instance”). In
    10 Petitioners also argue that the CWA, unlike the Clean Air Act (“CAA”), contains no
    provision for a stay pending reconsideration and this court should interpret the silence of the
    CWA in light of the CAA. To be sure, agencies, as mere creatures of statute, must point to
    explicit Congressional authority justifying their decisions. Bowen v. Georgetown Univ. Hosp.,
    
    488 U.S. 204
    , 208, 
    109 S. Ct. 468
    , 471 (1988) (“It is axiomatic that an administrative agency’s
    power to promulgate legislative regulations is limited to the authority delegated by
    Congress.”). But EPA implemented the Postponement Rule through the rulemaking process,
    not as a discretionary stay. Petitioners cite no authority suggesting that statutory grants of
    power must be read as narrowly as possible, nor do they cite any authority suggesting that
    the EPA’s power to revise under the CWA does not extend to effective dates and compliance
    dates.
    7
    Case: 18-60079        Document: 00515094677           Page: 8     Date Filed: 08/28/2019
    No. 18-60079
    accord with these authorities, EPA issued the Postponement Rule following
    notice-and-comment rulemaking after evaluating legitimate concerns about
    compliance costs and achievability.
    Petitioners alternatively contend that even if the Postponement Rule is
    not actually a stay of the 2015 Rule, then its relaxation of certain compliance
    dates is the “functional equivalent” of a stay, which the Clean Water Act does
    not authorize. But courts have rejected EPA delay actions undertaken without
    notice and comment rulemaking precisely because they recognize that the
    modification of effective dates is itself a rulemaking. See, e.g., Envtl. Def. Fund
    v. Gorsuch, 
    713 F.2d 802
    , 815–17 (D.C. Cir. 1983) (stating general rule that
    changes to effective dates constitute rulemaking and rejecting agency's
    argument that its decision not to call for hazardous waste permits from a whole
    class of facilities was a policy statement); Council of S. Mountains, Inc. v.
    Donovan, 
    653 F.2d 573
    , 580 n.28 (D.C. Cir. 1981); Envt’l Def. Fund, Inc. v. EPA,
    
    716 F.2d 915
    , 920 (D.C. Cir. 1983) (“[S]uspension or delayed implementation
    of a final regulation normally constitutes substantive rulemaking under APA
    § 553.”). As the Second Circuit explained, “altering the effective date of a duly
    promulgated standard could be, in substance, tantamount to an amendment or
    rescission of the standards.” Nat. Res. Def. Council v. Abraham, 
    355 F.3d 179
    ,
    194 (2d Cir. 2004). 11 Courts have rebuked EPA delays as illegitimate where
    11Intentionally delaying implementation of a duly promulgated rule may be analogous
    to an agency’s issuing a rule that is inconsistent with a prior rule. In the latter situation, the
    D.C. Circuit, quoting Judge Easterbrook, holds that such a rule is necessarily a revision of
    the prior rule, which is permissible as long as pursued through the appropriate
    administrative processes:
    It is a maxim of administrative law that: “If a second rule repudiates or is
    irreconcilable with [a prior legislative rule], the second rule must be an
    amendment of the first; and, of course, an amendment to a legislative rule must
    itself be legislative.” Michael Asimow, Nonlegislative Rulemaking and
    Regulatory Reform, 1985 Duke L.J. 381, 396. Judge Easterbrook has lucidly
    explained why in such circumstances notice and comment rulemaking must be
    followed: A volte face . . . may be an attempt to avoid the notice and opportunity

    No. 18-60079
    the agency did not go through notice and comment procedures. See, e.g., Nat.
    Res. Def. Council v. Nat’l Highway Traffic Safety Admin., 
    894 F.3d 98
    , 113–14
    (2d Cir. 2018); Air Alliance 
    Houston, 906 F.3d at 1065
    (“EPA may not employ
    delay tactics to effectively repeal a final rule while sidestepping the statutorily
    mandated process for revising or repealing that rule on the merits”) (citation
    omitted); Clean Air 
    Council, 862 F.3d at 9
    (agency “issuing a legislative rule is
    itself bound by the rule until that rule is amended or revoked” and “may not
    alter [that rule] without notice and comment”). EPA obviated the Petitioners’
    complaint because the way in which it modified the 2015 Rule is a rulemaking
    that may properly issue after notice and comment.
    B. Whether the Postponement Rule complied with the APA.
    Petitioners do not prevail by describing the Postponement Rule as a stay
    or something other than a notice-and-comment rulemaking. They next assert
    that “[d]espite citing the Clean Water Act provisions for issuing or revising
    effluent limitations as the authority for the [Postponement] Rule, EPA failed
    to consider all of the factors that the statute requires to be considered when
    promulgating effluent limits.” They point to the various statutory factors that
    for comment that the Administrative Procedure Act requires for the alteration
    of a rule. When an agency gets out the Dictionary of Newspeak and pronounces
    that for purposes of its regulation war is peace, it has made a substantive
    change for which the APA may require procedures. If in the air bags case,

    Insurance Co.,

    77 L. Ed. 2d 443
    (1983), instead of
    repealing the rule the agency had proclaimed that an ordinary seat belt is a
    “passive restraint”, the Court would have treated this the same as it treated
    revocation of the rule. Both require notice, an opportunity for comment, and
    an adequate record. Homemakers North Shore, Inc. v. Bowen,

    No. 18-60079
    must govern BAT findings that undergirded the ELGs in the 2015 Rule. 12 They
    contend that because EPA failed to repeat, restate, re-evaluate and re-explain
    each of those “mandatory” factors, its Postponement Rule was invalid as “in
    excess of statutory authority” pursuant to the APA, 5 U.S.C. § 706(2). We
    disagree.
    In this rulemaking proceeding, EPA revised only a subset of the 2015
    Rule in response to serious issues raised about the availability and
    achievability of those particular regulations.           The agency sought to avoid
    imposing potentially needless compliance costs, carefully considered which
    portions of the Rule to revise, and ultimately chose to modify only the earliest
    compliance dates for only two of the wastestreams. As EPA emphasizes, all of
    the relevant statutory factors were considered in the 2015 Rule. See, e.g., EPA,
    Technical Development Document for the Effluent Limitations Guidelines and
    Standards for the Steam Electric Power Generating Point Source Category,
    Index. 12840, at 8-6 to 8-25 (discussing evidence in the record on each of the
    statutory factors for BAT) (Sept. 2015); 80 Fed. Reg. at 67,846–47, 67,854–56,
    67,863–69 (same). All of the findings were incorporated in the administrative
    record for the Postponement Rule. See Administrative Record Index, Mar. 19,
    2018, ECF No. 00514391502.                Finally, EPA expressly identified the
    Postponement Rule as a follow-on rulemaking to the 2015 Rule. In large part,
    the Postponement Rule repeats the substance of the 2015 Rule.
    Moreover, EPA has significant discretion to weigh the statutory factors
    and re-evaluate the policy arguments supporting the rule. See Nat’l Ass’n of
    Home Builders v. EPA, 
    682 F.3d 1032
    , 1038 (D.C. Cir. 2012) (stating that “a
    12The CWA requires that BAT be based on a consideration of “the age of equipment
    and facilities involved, the process employed, the engineering aspects of the application of
    various types of control techniques, process changes, the cost of achieving such effluent
    reduction, non-water quality environmental impact (including energy requirements), and
    such other factors as the Administrator deems appropriate.” 33 U.S.C. § 1314(b)(2)(B).

    reappraisal of the costs and benefits of its programs and regulations” (citing
    Motor Vehicle Mfrs. 
    Ass’n, 463 U.S. at 59
    (Rehnquist, J., concurring in part and
    dissenting in part)). The CWA allows the Administrator discretion, in addition
    to applying the other enumerated factors, to consider “other factors as the
    Administrator deems appropriate.”       33 U.S.C. § 1314(b)(2)(B).    The “other
    factor” deemed important here had to do with the 2015 Rule’s technology:
    “serious concerns about the availability and affordability of the technology
    basis for the FGD wastewater and bottom ash transport water requirements
    in the 2015 [ELG] Rule” were “important issues that warrant further
    consideration.” Postponement Rule, 82 Fed. Reg. at 43,496–97.
    Under these circumstances, EPA violated no statutory command by
    revising a small portion of the 2015 Rule pursuant to transparent, careful and
    targeted study.    The agency supplied a reasoned basis for its decision to
    postpone two earliest compliance dates for the two specific waste streams,
    while retaining not only the ultimate compliance deadline specified in the 2015
    Rule for those waste streams but practically the entirety of the 2015 Rule itself.
    The agency supplied a reasoned basis for its action, and accomplished the
    revision using “the same procedures when they amend[ed] . . . a rule as they
    used to issue the rule in the first instance.”

    C. Whether the Postponement Rule complies with 33 U.S.C.
    § 1311(b)(2).
    Petitioners’ last contention is that the Postponement Rule violates what
    they assert is a mandatory maximum three-year compliance deadline for any
    BAT effluent limitations promulgated under the CWA. The CWA requires that
    “there shall be achieved . . . compliance with [BAT] effluent limitations . . . as
    expeditiously as practicable but in no case later than three years after the date
    such limitations are promulgated . . . , and in no case later than March 31,
    1989.”       33 U.S.C. § 1311(b)(2)(C). 13      Petitioners argue that this provision
    forbids EPA from extending compliance dates for any BAT effluent limitations
    beyond three years from the date of promulgation. Since the BAT effluent
    limitations in the 2015 Rule were promulgated on November 3, 2015, the
    deadline by this reckoning would be November 3, 2018. In its own terms, of
    course, the Postponement Rule extends the earliest compliance dates to
    November 1, 2020, which would run afoul of Petitioners’ interpretation.
    EPA argues that this statutory language dealt only with the initial
    promulgation of BAT effluent limitations, and the agency retains discretion to
    set compliance dates for any BAT subsequent effluent limitations. We agree
    with the agency. The plain text of the statute indicates that the three-year
    compliance deadline refers only to promulgation of the initial BAT effluent
    limitations. 14 The “in no case later than three years” language is modified by
    13   Subsections (D) and (F) include identical language.
    14 Because the text is clear, there is no occasion here for deference to the
    administrative agency’s reading of the statute under Chevron, U.S.A., Inc. v. Nat. Res. Def.
    Council, Inc., 
    467 U.S. 837
    , 
    104 S. Ct. 2778
    (1984). Under “step one” of Chevron, courts
    analyze the statutory text for ambiguity. 
    Id. at 843–44,
    104 S. Ct. at 2781–82. If the text is
    ambiguous, courts defer to the agency’s reasonable interpretation of the statute. 
    Id. But if
    the meaning of the law is clear – if there is no ambiguity – this court applies the law without
    deference to the agency. See Luminant Generation Co. v. EPA, 
    714 F.3d 841
    , 850–52 (5th
    Cir. 2013).

    No. 18-60079
    the deadline “and in no case later than March 31, 1989.” Petitioners’ reading
    of the statute is absurd, as it is impossible to require compliance with BAT
    effluent limitations both within three years of the 2015 Rule and by March 31,
    1989. EPA’s reading of the text accords the language its natural meaning: the
    initial BAT effluent limitations were to be complied with as expeditiously as
    practicable, but in no case later than three years after promulgation, with a
    final compliance date of March 31, 1989 at the latest. Regulated parties had
    to comply with EPA’s initial BAT effluent limitations either within three years
    of promulgation or by March 31, 1989 – whichever came first. This reading is
    supported by § 1311(d), which requires EPA periodically to review BAT
    limitations, including after 1989, but contains no such compliance deadline.
    See 33 U.S.C. § 1311(d) (“Any effluent limitation required by paragraph (2) of
    subsection (b) of this section shall be reviewed at least every five years and, if
    appropriate, revised pursuant to the procedure established under such
    paragraph.”). And Petitioners must concede that, contrary to their argument,
    even the 2015 Rule allowed for compliance dates later than three years after it
    first took effect.
    Petitioners’ additional contentions are unavailing.       First, Petitioners
    argue that the statutory purposes and legislative history suggest that reading
    a three-year compliance requirement even after 1989 would be most consistent
    with the CWA’s “overall goal to eliminate all discharges of pollution into
    navigable waters.” Pretermitting the propriety of this reading, courts cannot
    resort to statutory purposes and legislative history and set aside the plain
    meaning of the statute. Second, Petitioners cite Chem. Mfrs. Ass’n v. EPA,
    
    870 F.2d 177
    , 242 (5th Cir.), clarified on reh’g, 
    885 F.2d 253
    (5th Cir. 1989), for
    the proposition that the three-year statutory deadline is mandatory, and EPA’s
    discretion extends only to deciding how to enforce the deadline. But that case
    13
    Case: 18-60079    Document: 00515094677      Page: 14   Date Filed: 08/28/2019

    concerned only a challenge to the original 1989 deadline, and did not address
    whether the statute also required maximum three-year compliance deadlines
    for any BAT effluent limitations promulgated thereafter. Petitioners identify
    no case law in support of their atextual interpretation. Finally, Petitioners
    suggest that the CWA’s system of periodic review and revision would be
    meaningless without mandatory deadlines for compliance. But it was not
    meaningless for Congress to require three-year compliance deadlines for the
    initial promulgation of BAT effluent limitations, given the pressing need for
    regulation at that time. Even without specific Congressional direction, EPA
    has not been powerless in setting appropriate compliance deadlines for later
    revised BAT effluent limitations.
    CONCLUSION
    In response to new information provided to it about the availability and
    achievability of a subset of regulations contained in a previously-promulgated
    rule, EPA revised its prior rule by changing only the earliest compliance dates
    applicable only to that subset of the regulations which had the potential to
    impose needless compliance costs. EPA engaged in incremental and targeted
    rulemaking following a period of notice and comment.         In the end, most
    elements of the prior rule remained intact. EPA had statutory authority to
    pass this tailored Postponement Rule, the agency provided a reasoned basis for
    its decision, and its decision was reasonable, not arbitrary or capricious. The
    petition for review is DENIED.
