    Before: HENDERSON and ROGERS, Circuit Judges, and
    SENTELLE, Senior Circuit Judge.
    Opinion for the court by Circuit Judge ROGERS.
    ROGERS, Circuit Judge: In 1976, Congress enacted the
    Resource Conservation and Recovery Act of 1976 (“RCRA”),
    as amended, 42 U.S.C. §§ 6901–6992k, to address the
    environmental and health risks associated with hazardous solid
    waste. Subtitle C of RCRA required the Environmental
    Protection Agency to issue regulations governing the storage,
    treatment, and disposal of “solid waste,” which was defined as
    “discarded” material, 42 U.S.C. § 6903(27). Among RCRA’s
    stated objectives was “minimizing the generation of hazardous
    waste . . . by encouraging process substitution, materials
    recovery, properly conducted recycling and reuse, and
    treatment.” 
    Id. § 6902(a)(6)
    (emphasis added). In 2008, EPA
    promulgated a final rule that treated material transferred from
    a waste generator to a third-party reclaimer as legitimately
    recycled, rather than “discarded” and subject to Subtitle C
    regulation, if several conditions were met. This Transfer-
    Based Exclusion was replaced by another exclusion in 2015,
    reinstated by the court in 2017, and reissued by EPA as
    modified in 2018.
    Environmental petitioners consider the Transfer-Based
    Exclusion to be insufficiently protective of human health and
    the environment and bring two challenges: First, they contend
    3
    the Transfer-Based Exclusion exceeds EPA’s statutory
    authority under RCRA. In their view, a generator “discards”
    hazardous material whenever it pays a reclaimer to accept the
    material. Second, they contend the Transfer-Based Exclusion
    fails arbitrary and capricious review because EPA has not
    provided a reasoned explanation for treating hazardous
    material differently based on whether it is sent to a reclaimer
    instead of a storage, treatment, or disposal facility, and because
    EPA has already identified deficiencies in the Transfer-Based
    Exclusion.
    EPA initially raises a host of threshold objections to
    petitioners’ contentions, some of which industry intervenors
    join. Upon examination, we conclude none is persuasive. On
    the merits, EPA responds that neither the statutory text, case
    law, nor empirical data supports petitioners’ contentions. We
    conclude, in view of this court’s precedent, that EPA did not
    act contrary to RCRA in adopting the Transfer-Based
    Exclusion because hazardous secondary materials are not
    necessarily “discarded” each time they are transferred from a
    generator to a reclaimer along with payment. Further we
    conclude that EPA has provided a reasoned explanation for
    applying different standards to materials that are not yet part of
    the waste disposal problem RCRA addresses where they meet
    conditions EPA concluded were adequate for safe transfer and
    legitimate recycling. The Transfer-Based Exclusion therefore
    survives arbitrary and capricious review. Accordingly, we
    deny the petition for review.
    I.
    Some background is necessary before addressing the
    threshold objections to petitioners’ challenge.
    4
    A.
    In 2008, EPA promulgated a final rule intended to
    “encourage and expand the safe, beneficial recycling of
    additional hazardous secondary materials,” adopting the
    Generator-Controlled Exclusion and the Transfer-Based
    Exclusion. The Exclusions deal with “reclamation,” a type
    of recycling that occurs when secondary material is
    processed to recover a usable product or is regenerated. 40
    C.F.R. § 261.1(c)(4), (7). Secondary materials can include
    byproducts, spent materials, and sludges. 
    Id. § 261.1(c)(1)–
    (3). The final rule allowed generators of hazardous secondary
    materials to avoid Subtitle C regulation of those materials
    where the generator controls the recycling or where the
    generator transfers the materials to an off-site reclaimer.
    Revisions to the Definition of Solid Waste, 73 Fed. Reg. 64,668,
    64,669 (Oct. 30, 2008) (“2008 Rule”). Under the Transfer-
    Based Exclusion, generators, transporters, and reclaimers must
    meet “Transfer Conditions” to ensure hazardous materials are
    transferred securely and are actually recycled. 
    Id. at 64,669–
    70. For example, a generator must audit the reclaimer for
    compliance with proper recycling practices. 
    Id. at 64,683.
    “Legitimacy Factors” must also be satisfied so recycling is
    legitimate and not a “sham.” 
    Id. at 64,670.
    The history of the
    Rule is described in American Petroleum Institute v. EPA
    (“API III”), 
    862 F.3d 50
    (D.C. Cir. 2017).
    Suffice it to say, environmental groups challenged the
    2008 Rule as too lenient, and industry groups challenged the
    Rule as too strict. EPA eventually replaced the Transfer-Based
    Exclusion in 2015 with a similar but more restrictive Verified
    Recycler Exclusion, allowing generators to avoid Subtitle C
    requirements only when they transfer materials to verified
    recyclers that had obtained either permits or variances.
    Definition of Solid Waste, 80 Fed. Reg. 1694, 1695 (Jan. 13,
    2015) (“2015 Rule”). Environmental and industry groups
    5
    challenged this Exclusion, and in API III, the court vacated the
    permit and variance provisions, reinstated the 2008 Transfer-
    Based Exclusion, and upheld other requirements regarding
    emergency preparedness and containment added in 2015. On
    rehearing, the court expanded the Transfer-Based Exclusion to
    cover spent refinery catalysts. American Petroleum Institute v.
    EPA (“API IV”), 
    883 F.3d 918
    (D.C. Cir. 2018). Without
    further notice and comment, EPA then published in 2018 the
    Transfer-Based Exclusion as modified by this court, which
    petitioners now challenge. Response to Vacatur of Certain
    Provisions of the Definition of Solid Waste Rule, 83 Fed. Reg.
    24,664 (May 30, 2018) (“2018 Rule”). The court is presented
    with an unusual time warp in considering petitioners’
    challenges to the Transfer-Based Exclusion given the passage
    of 10 years during which EPA considered policy concerns and
    the court addressed legal challenges.
    B.
    The court first must address the threshold objections raised
    by EPA and joined in part by industry intervenors.
    1. Standing. To satisfy “the irreducible constitutional
    minimum of standing,” a party must establish (1) that it has
    “suffered an injury in fact” that is both “concrete and
    particularized” and “actual or imminent,” (2) that the injury is
    “fairly trace[able] to the challenged action of the defendant,”
    and (3) that the injury is “likely . . . [to] be redressed by a
    favorable decision.” Lujan v. Defs. of Wildlife, 
    504 U.S. 555
    ,
    560–61 (1992) (first alteration in original). Contrary to EPA’s
    objection, petitioners have established standing.
    For an organization to bring suit on behalf of its members,
    it must show (1) at least one of “its members would otherwise
    have standing to sue in [his or her] own right,” (2) “the interests
    it seeks to protect are germane to the organization’s purpose,”
    6
    and (3) “neither the claim asserted nor the relief requested
    requires the participation of individual members.” Defs. of
    Wildlife v. Perciasepe, 
    714 F.3d 1317
    , 1323 (D.C. Cir. 2013).
    Petitioners’ members live, commute, work, and recreate near
    generators of hazardous materials that used the Transfer-Based
    Exclusion before 2015 or that are likely to use it now. See
    Feldman Decl. ¶¶ 3–4; Ford Decl. ¶ 3; Kilgour Decl. ¶¶ 5–7;
    Rhodes Decl. ¶¶ 2–3. By parity of reasoning, just as the court
    has recognized industry groups’ standing based on injury
    caused by elimination of parts of the Exclusion, e.g., API 
    III, 862 F.3d at 66
    , the Transfer-Based Exclusion deprives
    petitioners’ members of Subtitle C protections that Congress
    deemed necessary to address health or environmental risks.
    Congress acknowledged the potential threat to human health
    and the environment associated with hazardous wastes when it
    required EPA to promulgate regulations governing their
    storage, treatment, and disposal. 42 U.S.C. § 6903(5)(B). By
    definition, the existing Subtitle C regulations are those EPA has
    determined to be “necessary to protect human health and the
    environment.” 
    Id. §§ 6922(a),
    6923(a), 6924(a). In their
    declarations, petitioners’ members describe how their
    reasonable fear of those same health or environmental risks
    impairs their ability to feel safe and to enjoy the outdoors.
    Several declarants state that they spend less time outdoors
    exercising, gardening, walking their dogs, or fishing, or do not
    enjoy these outdoor activities as much, due to their worries
    about health and environmental harms. Cheung Decl. ¶¶ 10–
    11; Feldman Decl. ¶¶ 6–9; Ford Decl. ¶¶ 6–8; Kilgour Decl.
    ¶ 10.
    This court has concluded in similar circumstances that
    environmental petitioners have standing to challenge
    regulatory actions under RCRA. In Sierra Club v. EPA, 
    755 F.3d 968
    (D.C. Cir. 2014), the court held that similar
    declarations explaining “individuals’ particularized fears of
    7
    serious health and environmental consequences” and “their
    individual behavioral changes” resulting from the regulatory
    change established injury in fact for Article III standing. 
    Id. at 974–75.
    Similarly, in NRDC v. EPA, 
    755 F.3d 1010
    (D.C. Cir.
    2014), the court deemed sufficient “declarations of long-time
    members who spend time near facilities which, as a result of
    the [challenged] Exclusion, now burn comparable fuels” and
    who “spend less time outdoors” due to their “concern[] about
    the emissions’ effects on their health.” 
    Id. at 1016–17.
    If a
    challenged regulation causes individuals to reasonably fear
    health or environmental harms and thus prevents them from
    using or enjoying the aesthetic or recreational value of their
    area, their injury suffices for Article III standing. See Friends
    of the Earth, Inc. v. Laidlaw Envtl. Servs. (TOC), Inc., 
    528 U.S. 167
    , 182–83 (2000); Ass’n of Battery Recyclers, Inc. v. EPA,
    
    716 F.3d 667
    , 672–73 (D.C. Cir. 2013).
    The seven years the Transfer-Based Exclusion was in
    effect have not, as EPA suggests, rendered petitioners’
    concerns speculative. During that time, only a small subset of
    the industry facilities eligible for the Exclusion took advantage
    of it. See API 
    III, 862 F.3d at 66
    ; compare 2008 Rule, 73 Fed.
    Reg. at 64,668 (5,600 facilities eligible for 2008 Exclusion),
    with 2015 Rule, 80 Fed. Reg. at 1,708 (65 facilities utilizing
    Exclusion in April 2014). Industry intervenors acknowledge
    that most states refrained from adopting the Transfer-Based
    Exclusion “due to uncertainty over the long-term status of the
    exclusion.” Intervenor-Respondents’ Br. 12–13. But facilities
    now qualifying for the Exclusion are likely to “take advantage
    of the Exclusion for which they lobbied” EPA, Sierra 
    Club, 755 F.3d at 975
    , as indicated by industry intervenors’ claim of
    standing on this basis. See Intervenor-Respondents’ Br. 3.
    2. Waiver. Generally, “a party must initially present its
    comments to the agency during the rulemaking in order for the
    8
    court to consider the issue.” Tex Tin Corp. v. EPA, 
    935 F.2d 1321
    , 1323 (D.C. Cir. 1991). Its objections must be stated
    “with sufficient specificity reasonably to alert the agency.”
    Appalachian Power Co. v. EPA, 
    251 F.3d 1026
    , 1036 (D.C.
    Cir. 2001) (quoting Tex Tin 
    Corp., 935 F.2d at 1323
    ). There is
    no waiver here.
    The waiver rule exists to “ensure an agency has had ‘an
    opportunity to consider the matter, make its ruling, and state
    the reasons for its action.’” Okla. Dep’t of Envtl. Quality v.
    EPA, 
    740 F.3d 185
    , 192 (D.C. Cir. 2014) (quoting
    Unemployment Comp. Comm’n of Alaska v. Aragon, 
    329 U.S. 143
    , 155 (1946)). EPA had an opportunity to and did address
    petitioners’ contentions during the notice-and-comment period
    for the 2008 Rule. Although EPA attempts to recast
    petitioners’ current contentions as new, Sierra Club raised the
    same concerns in 2007 as petitioners here about the relevance
    of generators’ payment to recyclers and the insufficiency of the
    Transfer Conditions. EPA’s Response to Comments shows it
    was aware of these objections to the proposed rule. See 
    NRDC, 755 F.3d at 1022
    –23.
    Regarding the payment issue, EPA quoted Sierra Club’s
    concerns, see Revisions to the Definition of Solid Waste,
    Response to Comments Document, 88 (Oct. 1, 2008), and
    explained that although it would not “mak[e] its finding on
    discard solely based on the ‘value’ of the recycled material[,]
    ‘[v]alue’ is one aspect of the Agency’s findings and[]
    contributes to the ultimate determination that materials
    complying with the conditions and restrictions of this
    regulation are not discarded,” 
    id. at 91.
    Regarding the sufficiency of the Transfer Conditions, EPA
    noted commenters’ views that “before EPA can lawfully claim
    that excluded materials are not discarded, the Agency would
    9
    need to strengthen the conditions to protect human health and
    the environment” and that “the minimal conditions in the
    proposal are not sufficient to protect against discard.” 
    Id. at 86.
    EPA disagreed that the Transfer Conditions were inadequate,
    stating that “[e]ach of the restrictions and/or conditions is
    specifically linked to defining when the hazardous secondary
    materials are not discarded.” 
    Id. at 91–95.
    3. Timeliness. RCRA provides that parties may seek
    review in this court of EPA regulations “within ninety days
    from the date of such promulgation . . . or after such date if
    such petition for review is based solely on grounds arising after
    such ninetieth day.” 42 U.S.C. § 6976(a)(1) (emphasis added).
    The circumstances leading to the instant petition are a classic
    example of the “after-arising grounds” exception. Petitioners
    timely raised their challenges to the Transfer-Based Exclusions
    of 2008 and 2018.
    Petitioners filed the instant challenge to the 2008 Rule and
    the Transfer-Based Exclusion reissued in 2018 on June 12,
    2018 (within 90 days of the 2018 issuance but not within 90
    days of the 2008 Rule). The after-arising grounds exception to
    the 90-day time limit “encompasses the occurrence of an event
    that ripens a claim.” Coal. for Responsible Regulation, Inc. v.
    EPA, 
    684 F.3d 102
    , 129–30 (D.C. Cir. 2012). In January 2009,
    Sierra Club petitioned for review of the 2008 Rule and sought
    reconsideration by EPA. Within a month EPA indicated it
    would consider withdrawing the rule and proposing a new one
    to address Sierra Club’s concerns. The court granted the joint
    motion of Sierra Club and EPA to hold the petition in abeyance.
    EPA promulgated a new rule in 2015, at which point Sierra
    Club dismissed its petition for review without prejudice to
    challenges to future rules, in accordance with its 2010
    settlement agreement with EPA. See API 
    III, 862 F.3d at 56
    .
    10
    Sierra Club’s challenge to the 2008 Rule would have been
    unripe in view of EPA’s expressed intention to withdraw the
    Transfer-Based Exclusion. The court so held with regard to
    industry groups’ petition challenging the 2008 Rule. See Am.
    Petroleum Inst. v. EPA (“API II”), 
    683 F.3d 382
    , 384, 387–88
    (D.C. Cir. 2012). The court’s decisions in 2017 and 2018 and
    EPA’s reissuance in 2018 of a Transfer-Based Exclusion had
    the effect of re-ripening Sierra Club’s challenge. See Coal. for
    Responsible 
    Regulation, 684 F.3d at 131
    . The court’s “‘finding
    of unripeness gives petitioners the needed assurance’ that they
    will not be foreclosed from judicial review when the
    appropriate time comes.” Grand Canyon Air Tour Coal. v.
    FAA, 
    154 F.3d 455
    , 473 (D.C. Cir. 1998) (quoting Public
    Citizen v. Nuclear Regulatory Comm’n, 
    940 F.2d 679
    , 683
    (D.C. Cir. 1991)).
    The court’s decision in Alaska v. Department of
    Agriculture, 
    772 F.3d 899
    (D.C. Cir. 2014), is to similar effect.
    A 2001 Forest Service rule prohibited road construction on
    national forest lands. The Forest Service repealed the rule in
    2005, but a district court reinstated it in 2006. 
    Id. at 900.
    This
    court rejected the Forest Service’s timeliness objection,
    holding that when the rule was reinstated in 2006 after its prior
    repeal, a new right of action accrued under the reopening
    doctrine “even though the regulation challenged is no
    different.” 
    Id. (citing Ohio
    v. EPA, 
    838 F.2d 1325
    , 1328 (D.C.
    Cir. 1988)). The case for timeliness here is stronger than in
    Alaska because the 2018 Transfer-Based Exclusion differs
    from the 2008 version of the Transfer-Based Exclusion. For
    example, the 2018 version includes emergency preparedness
    and containment requirements first added in 2015 and also now
    applies to spent refinery catalysts. See API 
    III, 862 F.3d at 66
    –
    67, 75; API 
    IV, 883 F.3d at 923
    .
    11
    4. Claim Preclusion. Under the doctrine of claim
    preclusion, “a final judgment on the merits of an action
    precludes the parties or their privies from relitigating issues
    that were or could have been raised in that action.” Allen v.
    McCurry, 
    449 U.S. 90
    , 94 (1980). “A subsequent lawsuit is
    barred by claim preclusion ‘if there has been prior litigation
    (1) involving the same claims or cause of action, (2) between
    the same parties or their privies, and (3) there has been a final,
    valid judgment on the merits, (4) by a court of competent
    jurisdiction.’” NRDC v. EPA, 
    513 F.3d 257
    , 260 (D.C. Cir.
    2008) (quoting Smalls v. United States, 
    471 F.3d 186
    , 192
    (D.C. Cir. 2006)). Because the instant petition involves a
    different Transfer-Based Exclusion, claim preclusion does not
    bar petitioners’ contentions.
    Petitioners do not raise the same claims as they raised or
    could have raised in 2015 because the Verified Recycler
    Exclusion and the 2018 Transfer-Based Exclusion are
    different. See API 
    III, 862 F.3d at 64
    –65, 75. A judgment “bars
    any further claim based on the same ‘nucleus of facts,’” but
    where an earlier action “could not have asserted claims based
    on facts that were not yet in existence,” dismissal based on
    claim preclusion is not allowed. Page v. United States, 
    729 F.2d 818
    , 820 (D.C. Cir. 1984); see also Drake v. FAA, 
    291 F.3d 59
    , 66 (D.C. Cir. 2002). Claim preclusion “does not
    preclude a suit arising from a completely different event, no
    matter how similar the defendant’s []conduct.” Russian Media
    Grp., LLC v. Cable Am., Inc., 
    598 F.3d 302
    , 311 (7th Cir. 2010)
    (citing Lawlor v. Nat’l Screen Serv. Corp., 
    349 U.S. 322
    , 328
    (1955)). As petitioners note, the Transfer-Based Exclusion did
    not exist in its current form when they challenged the 2015
    Rule in API III & IV; therefore, the causes of action here and
    there are not the same.
    12
    5. Issue Preclusion. Under the doctrine of issue
    preclusion, “once a court has decided an issue of fact or law
    necessary to its judgment, that decision may preclude
    relitigation of the issue in a suit on a different cause of action
    involving a party to the first case.” 
    Allen, 449 U.S. at 94
    . A
    prior holding has preclusive effect if three requirements are
    met: (1) “the same issue now being raised must have been
    contested by the parties and submitted for judicial
    determination in the prior case;” (2) “the issue must have been
    actually and necessarily determined by a court of competent
    jurisdiction in that prior case;” and (3) “preclusion in the
    second case must not work a basic unfairness to the party
    bound by the first determination.” Yamaha Corp. of Am. v.
    United States, 
    961 F.2d 245
    , 254 (D.C. Cir. 1992). For an issue
    to be actually and necessarily decided by a prior court, the
    determination must be essential to the court’s judgment. 
    Id. That is
    not the case here.
    Although petitioners raised the same issues in API III, the
    court did not actually and necessarily decide them. In API III,
    the court identified the issues before it:
    Industry Petitioners argue that both the legitimacy test
    and the Verified Recycler Exclusion exceed EPA’s
    RCRA authority. Industry Petitioners also challenge
    EPA’s treatment of two specific materials: spent
    catalysts and off-specification commercial chemical
    products. Environmental Petitioners argue that the
    Verified Recycler Exclusion is too permissive and that
    EPA should have added containment and notification
    conditions to the 32 pre-2008 exclusions. We consider
    these challenges in 
    turn. 862 F.3d at 56
    . The court also was careful to identify that it
    resolved only the issues raised by industry petitioners. The
    13
    court agreed that EPA had not sufficiently justified its decision
    to tighten the conditions to require administrative approval
    through a permit or variance, 
    id. at 65,
    and therefore vacated
    the Verified Recycler Exclusion, 
    id. at 71.
    As a result, the court
    stated it “need not address Environmental Petitioners’
    argument that the exclusion is too lenient.” 
    Id. at 72.
    Nothing in the opinions in API III or API IV indicates the
    court rejected petitioners’ contention that generators discard
    such materials by paying to get rid of them. This makes sense
    because the court had no need to consider petitioners’
    challenges once it decided to vacate the Exclusion based on
    industry groups’ challenge. See Cement Kiln Recycling Coal.
    v. EPA, 
    255 F.3d 855
    , 872 (D.C. Cir. 2001).
    6. Stare Decisis. Stare decisis means that “the same issue
    presented in a later case in the same court should lead to the
    same result.” In re Grant, 
    635 F.3d 1227
    , 1232 (D.C. Cir.
    2011) (emphasis omitted) (quoting LaShawn A. v. Barry, 
    87 F.3d 1389
    , 1393 (D.C. Cir. 1996)). “Stare decisis compels
    adherence” only if the prior court reached a “factually
    indistinguishable decision.” Brewster v. Comm’r, 
    607 F.2d 1369
    , 1373 (D.C. Cir. 1979). No court has expressly decided
    whether hazardous materials that a generator pays a reclaimer
    to accept are necessarily “discarded” under RCRA.
    Petitioners’ challenges are not barred by stare decisis.
    In API III, 
    862 F.3d 50
    , the court discussed the confluence
    of transfer and low-value materials, but it did so only in the
    context of the industry groups’ arbitrary-and-capricious
    challenge to the 2015 Verified Recycler Exclusion. See 
    id. at 67–71.
    The court held that, in the absence of supporting data,
    EPA’s theory was insufficient to justify the administrative
    approval requirements. The court did not address petitioners’
    contention that payment from a generator to a recycler
    14
    necessarily makes material “discarded” as a matter of statutory
    interpretation. See generally 
    id. No party
    has identified an
    opinion that has decided that issue. The court in API III also
    did not address petitioners’ contention that the Transfer
    Conditions are insufficient to protect human health and the
    environment because they are less stringent than Subtitle C
    requirements. See generally 
    id. II. On
    the merits, petitioners seek vacatur of the Transfer-
    Based Exclusion, 40 C.F.R. § 261.4(a)(24)–(25), as contrary to
    RCRA. The court may set aside the Transfer-Based Exclusion
    if it is “arbitrary, capricious, an abuse of discretion, or
    otherwise not in accordance with law,” 5 U.S.C. § 706(2)(A),
    or “in excess of statutory jurisdiction, authority, or limitations,”
    
    id. § 706(2)(C).
    See 42 U.S.C. §§ 6903(27), 6922–6924. In
    reviewing an agency’s interpretation of a statute it administers,
    the court applies the familiar two-step test of Chevron, U.S.A.,
    Inc. v. NRDC, 
    467 U.S. 837
    (1984): If Congress has “directly
    spoken to the precise question at issue,” then the court must
    “give effect to the unambiguously expressed intent of
    Congress”; otherwise the court defers to the agency’s
    reasonable interpretation of a statute it administers, 
    id. at 842–
    43.
    In RCRA, Congress required EPA to regulate both
    hazardous and non-hazardous “solid waste,” with more
    stringent requirements applying to hazardous waste. Subtitle
    C of RCRA establishes a “cradle-to-grave” regulatory structure
    for handling hazardous solid waste. 42 U.S.C. §§ 6921–6939g;
    Shell Oil Co. v. EPA, 
    950 F.2d 741
    , 745 (D.C. Cir. 1991). These
    provisions apply only to materials first qualifying as “solid
    waste,” and hence the statutory definition of “solid waste”
    underlies the EPA regulations at issue here. RCRA defines
    15
    “solid waste” as “any garbage, refuse, sludge from a waste
    treatment plant, water supply treatment plant, or air pollution
    control facility and other discarded material.” 42 U.S.C.
    § 6903(27) (emphasis added). If a material is “discarded,” it is
    a solid waste and “falls within the jurisdiction of [] EPA.” Shell
    
    Oil, 950 F.2d at 754
    . RCRA does not define “discarded
    material” as used in the statutory definition of “solid waste,”
    but by regulation EPA has clarified that the term includes
    recycled material in certain circumstances, 40 C.F.R.
    § 261.2(a)(2), (c). In 2008, EPA interpreted the term
    “discarded material” not to include hazardous secondary
    materials that are transferred to a reclaimer if they meet
    Transfer Conditions to ensure the materials are actually and
    properly recycled. See 2008 Rule, 73 Fed. Reg. at 64,675.
    Petitioners challenge the Transfer-Based Exclusion in the
    2008 Rule and as issued in 2018 following this court’s remand,
    40 C.F.R. §§ 261.2(a)(1), 261.4(a)(24), on the principal ground
    that material a generator pays to get rid of is “discarded” under
    the ordinary meaning of that term and thus constitutes “solid
    waste” that EPA lacks authority to exclude from Subtitle C
    requirements. See Pet’rs’ Br. 22. In their view, any ambiguity
    about the meaning of “discard” does not extend to materials
    generators pay to get rid of, which “fall so easily into the
    ordinary meaning of discarded.” 
    Id. Petitioners consider
    EPA’s focus on the Transfer Conditions to prevent secondary
    spills and leaks during transport to be irrelevant to the question
    of “discard,” noting EPA’s acknowledgement that generators
    “often ship these materials . . . to avoid the costs of disposing
    of the material” and “typically pay the reclamation facility to
    accept [them].” 
    Id. at 30
    (alterations in original) (quoting 2015
    Rule, 80 Fed. Reg. at 1707).
    Petitioners do not contend that either transfer or
    reclamation necessarily constitutes “discard.” They also do not
    16
    contend that hazardous secondary materials must always be
    treated as hazardous waste under RCRA. Instead, they contend
    that a generator’s payment to a reclaimer to accept such
    material necessarily indicates the material has negative value
    to the generator and the transfer is a means of getting rid of, or
    “discarding,” the material. See 
    id. at 31–32.
    Congress has not directly answered the question whether
    “discarded material” under RCRA includes hazardous
    secondary material that a generator has paid a reclaimer to
    accept. The parties do not point to anything in the statutory
    text, structure, or legislative history of RCRA that clearly
    answers whether “discarded” includes or excludes materials
    that a generator pays to transfer to a reclamation facility and
    that meet the Transfer Conditions. But this court’s precedent
    effectively forecloses petitioners’ plain-meaning contention
    that payment is determinative of “discard.”
    In American Mining Congress v. EPA (“AMC I”), 
    824 F.2d 1177
    (D.C. Cir. 1987), the court agreed with industry
    groups challenging EPA’s authority under RCRA to regulate
    materials destined for immediate recycling or reuse within an
    ongoing production process. The court concluded these
    materials were not “discarded” because they “ha[d] not yet
    become part of the waste disposal problem.” 
    Id. at 1186.
    The
    court recognized that the “ordinary, plain-English meaning of
    the word ‘discarded’ is ‘disposed of,’ ‘thrown away,’ or
    ‘abandoned.’” 
    Id. at 1184.
    Notably, the court declined to
    “attribute decisive significance to the ordinary meaning of [the]
    statutory language” because the court viewed EPA’s expansive
    plain-meaning interpretation not to comport with Congress’s
    objectives. 
    Id. In particular,
    the court was of the opinion that
    Congress’s likely intent was that the term “discarded” be read
    consistent with “everyday parlance” rather than “in its broadest
    sense.” 
    Id. at 1187.
    That is, in RCRA Congress sought to
    17
    address the “ever-increasing problem of solid waste disposal
    by encouraging the search for and use of alternatives to existing
    methods of disposal (including recycling).” 
    Id. at 1185–86
    (emphasis omitted). Critically for the instant case, the court
    held that EPA lacked authority under Subtitle C to regulate
    materials “destined for beneficial reuse or recycling in a
    continuous process by the generating industry itself.” 
    Id. In response
    to industry and environmental challenges, the
    court has since clarified how AMC I is properly understood,
    explaining that “discarded” is, in some circumstances,
    ambiguous with respect to EPA’s regulatory authority. See
    Am. Petroleum Inst. v. EPA (“API I”), 
    906 F.2d 729
    , 740 (D.C.
    Cir. 1990); Am. Mining Cong. v. EPA (“AMC II”), 
    907 F.2d 1179
    , 1186 (D.C. Cir. 1990); cf. Ass’n of Battery Recyclers,
    Inc. v. EPA, 
    208 F.3d 1047
    , 1056 (D.C. Cir. 2000). In API I,
    
    906 F.2d 729
    , the court acknowledged the ambiguity about
    EPA’s authority to regulate K061 slag, which is a “sludge” and
    therefore a “solid waste” when it leaves the electric furnace that
    generated it. 
    Id. at 740.
    There, EPA had promulgated a rule
    declining to regulate K061 slag once it reached a metal
    reclamation facility because it was no longer “discarded.” 
    Id. The court
    held EPA had overread AMC I and vacated the rule.
    An “equally plausible reading” of RCRA’s definition of “solid
    waste,” the court stated, “is that K061 remains ‘discarded’
    throughout the ‘waste treatment’ process dictated by the
    agency.” 
    Id. Therefore EPA’s
    contrary interpretation would
    be inconsistent with “RCRA’s acknowledged objective to
    ‘establish[] a cradle-to-grave regulatory structure’ for the safe
    handling of hazardous wastes.” 
    Id. at 741
    (alteration in
    original) (quoting United Techs. Corp. v. EPA, 
    821 F.2d 714
    ,
    716 (D.C. Cir. 1987)).
    In Shell Oil, 
    950 F.2d 741
    , the court confirmed that AMC
    I does not affect “EPA’s ability to regulate hazardous materials
    18
    after they have been discarded.” 
    Id. at 756.
    It upheld EPA’s
    interpretation that “[i]f a hazardous material has been
    discarded, it becomes subject to Subtitle C regulation even if it
    is sent to a resource recovery facility.” 
    Id. But in
    Association of Battery Recyclers, 
    208 F.3d 1047
    ,
    the court rejected EPA’s interpretation that materials are
    “discarded” if they are not immediately reused where they are
    destined for reclamation within an ongoing production process.
    
    Id. at 1052.
    The court held EPA had “misread[] passages [in
    AMC I] to mean that it may treat secondary materials as
    ‘discarded’ whenever they leave the production process and are
    stored for any length of time.” 
    Id. The court
    explained:
    “Congress clearly and unambiguously expressed its intent that
    ‘solid waste’ . . . be limited to materials that are ‘discarded’ by
    virtue of being disposed of, abandoned, or thrown away,” 
    id. at 1051
    (quoting AMC 
    I, 824 F.2d at 1193
    ), and “material stored
    for recycling is plainly not in that category,” 
    id. at 1053.
    The
    court reiterated AMC I’s conclusion that “secondary materials
    which are treated prior to recycling cannot be considered
    discarded if they are ‘reused within an ongoing industrial
    process.’” 
    Id. at 1054
    (quoting AMC 
    I, 824 F.2d at 1182
    )).
    Similarly, in Safe Food & Fertilizer v. EPA, 
    350 F.3d 1263
    (D.C. Cir. 2003), the court rejected environmental petitioners’
    contention, relying on AMC I, that transfer to another firm or
    industry for recycling necessarily means materials are
    “discarded.” 
    Id. at 1268.
    As the court explained, “we have
    never said that RCRA compels the conclusion that material
    destined for recycling in another industry is necessarily
    ‘discarded.’” 
    Id. The court
    pointed out that because “firms
    have ample reasons to avoid complete vertical integration,
    firm-to-firm transfers are hardly good indicia of a ‘discard’ as
    the term is ordinarily understood.” 
    Id. (citation omitted).
    The
    court accepted EPA’s exclusion of certain materials from
    19
    Subtitle C regulation if they met certain conditions under which
    “market participants treat the exempted materials more like
    valuable products than like negatively-valued wastes,
    managing them in ways inconsistent with discard.” 
    Id. at 1269.
    Finally, in API III, 
    862 F.3d 50
    , the court rejected EPA’s
    theory that additional stringency in the 2015 Verified Recycler
    Exclusion requiring a permit or variance was justified because
    the confluence of transfer and low-value materials creates
    perverse incentives for facilities to over-accumulate hazardous
    secondary materials without recycling them, resulting in
    “discard.” 
    Id. at 68–69.
    Because EPA “fail[ed] to provide
    sufficient linkage between theory, reality, and the result
    reached,” as required under State Farm, 
    id. at 68,
    EPA lacked
    a sufficient basis to issue a blanket rule finding “discard” and
    applying Subtitle C when the recycled material is transferred
    and of low value. 
    Id. at 65.
    The court’s precedent thus leaves no room to conclude that
    Congress directly resolved that “discarded material” must
    include hazardous secondary materials that a generator has paid
    a reclaimer to accept. Under the second part of the Chevron
    
    test, 467 U.S. at 843
    , the question is whether EPA’s
    interpretation is “based on a permissible construction of the
    statute.” It need not be “the only permissible construction, nor
    ‘the reading the court would have reached if the question
    initially had arisen in a judicial proceeding.’” Northpoint
    Techn., Ltd. v. FCC, 
    414 F.3d 61
    , 69 (D.C. Cir. 2005) (quoting
    
    Chevron, 467 U.S. at 843
    n.11). Deference is due to the
    agency’s permissible interpretation “if the agency has offered
    a reasoned explanation for why it chose that interpretation.”
    Vill. of Barrington, Ill. v. Surface Transp. Bd., 
    636 F.3d 650
    ,
    660 (D.C. Cir. 2011).
    20
    Petitioners contend EPA is not entitled to Chevron
    deference because it did not give a reasoned explanation for its
    interpretation of “discarded.” We disagree.
    EPA stated in the Preamble to the 2008 Rule that its
    interpretation of “discarded” “reflects the fundamental logic of
    the RCRA statute” and accords with this court’s “plain
    language definition of discard.” 2008 Rule, 73 Fed. Reg. at
    64,675–76. Although Congress’s “overriding concern” in
    enacting RCRA was to ensure proper waste management, H.R.
    REP. NO. 94-1491, at 3 (1976), it also aimed to encourage
    proper recycling and recovery of hazardous materials as an
    alternative to disposal, see 42 U.S.C. § 6902(a)(6). The House
    Committee’s Report concludes that properly conducted reuse,
    recycling, and reclamation are inconsistent with “discard,”
    stating that “[m]uch industrial and agricultural waste is
    reclaimed or put to new use and is therefore not a part of the
    discarded materials disposal problem the committee
    addresses.” H.R. REP. NO. 94-1491, at 2. In promulgating the
    2008 Rule, EPA acknowledged that Congress intended certain
    hazardous materials destined for recycling to be regulated.
    Excluding all hazardous secondary materials destined for
    recycling, EPA stated, “seems inconsistent with the mandate to
    track hazardous wastes and control them from ‘cradle to
    grave.’” 2008 Rule, 73 Fed. Reg. at 64,671. This court has
    embraced the view that if materials never become part of the
    waste disposal problem, then they are not “discarded” and need
    not be regulated under Subtitle C. E.g., AMC 
    I, 824 F.2d at 1179
    , 1186.
    In these circumstances, EPA has reasonably equated
    legitimate recycling with lack of “discard.” If the Transfer
    Conditions and Legitimacy Factors adequately ensure
    legitimate recycling, as EPA has determined, see 2018 Rule, 83
    Fed. Reg. at 24,665; 2008 Rule, 73 Fed. Reg. at 64,677–79,
    21
    then materials conforming to them are not “discarded.” The
    fact that generators pay reclaimers to accept certain materials
    may indicate the material has negative value and the generator
    is “getting rid of” it, as petitioners contend. On the other hand,
    EPA explained that payment may indicate only that a generator
    seeks alternatives to costly Subtitle C requirements and is
    willing to pay anything less than the compliance costs in order
    to recycle materials. See 2008 Rule, 73 Fed. Reg. at 64,675,
    64,677, 64,707. EPA relied on its market forces study to
    conclude that reclaimers may charge such a fee not because
    they must, but rather because they can as a result of a lack of
    competition in certain recycling markets. 
    Id. at 64,707.
    EPA
    also explained that generators may have to pay reclaimers to
    offset the reclaimers’ upfront capital costs to develop and
    implement the necessary recycling infrastructure and market.
    
    Id. Moreover, EPA’s
    Transfer-Based Exclusion does not
    ignore the potential relevance of payment as an indicator of
    “discard.” Instead these economic issues are part of its
    Legitimacy Factors analysis, see 
    id. at 64,706–07,
    which
    require that hazardous secondary material “provide[] a useful
    contribution to the recycling process,” that the recycling
    process “produce a valuable product or intermediate,” and that
    the generator and recycler manage the material “as a valuable
    commodity when it is under their control.” 40 C.F.R. § 260.43.
    Consequently, EPA’s decision in adopting the Transfer-
    Based Exclusion not to make payment from a generator to a
    reclaimer dispositive in assessing whether material is
    “discarded” is a permissible interpretation of “discard.”
    III.
    Agency action is arbitrary and capricious if it “has relied
    on factors which Congress has not intended it to consider,
    entirely failed to consider an important aspect of the problem,
    22
    offered an explanation for its decision that runs counter to the
    evidence before the agency, or is so implausible that it could
    not be ascribed to a difference in view or the product of agency
    expertise.” Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto.
    Ins. Co., 
    463 U.S. 29
    , 43 (1983). An agency must “articulate a
    satisfactory explanation for its action including a rational
    connection between the facts found and the choice made.” 
    Id. Agency action
    is also arbitrary and capricious if it “offered
    insufficient reasons for treating similar situations differently.”
    Transactive Corp. v. United States, 
    91 F.3d 232
    , 237 (D.C. Cir.
    1996).
    Petitioners contend the Transfer-Based Exclusion is
    arbitrary and capricious because EPA failed to provide a
    reasoned basis for treating the same hazardous materials
    differently and to account for its prior findings that the Transfer
    Conditions are inadequate. Given EPA’s reasoned explanation
    of the Transfer-Based Exclusion, we conclude these
    contentions are unpersuasive.
    A.
    EPA has sufficiently explained its different treatment of
    similar materials. Hazardous secondary materials destined for
    legitimate recycling are dissimilar in one key respect.
    Application of RCRA’s Subtitle C cradle-to-grave regulatory
    scheme depends on whether materials first qualify as “solid
    waste” because they are “discarded.”            See 42 U.S.C.
    § 6903(27). Materials that are not “discarded” are not subject
    to Subtitle C. Shell 
    Oil, 950 F.2d at 754
    . Subtitle C regulations
    aim to ensure that hazardous waste, once “discarded,” is
    transported, treated, and stored safely. See 42 U.S.C. §§ 6921–
    6939g. These regulations focus on waste that has made its way
    to a landfill, an incinerator, or a similar waste storage or
    treatment facility, in order to ensure that such waste does not
    contaminate local water supplies, generate toxic gases and
    23
    cause air pollution, combust, etc. See 
    id. § 6901(b).
    The
    Transfer Conditions, by contrast, seek to ensure that hazardous
    secondary materials do not end up in a landfill, incinerator, or
    similar facility but instead remain in a continuous stream or
    flow of production within industry processes. See AMC 
    I, 824 F.2d at 1190
    . They address potential risks by requiring the
    third-party reclaimers that accept such materials to handle them
    properly and safely and not to discard them. See 2008 Rule, 73
    Fed. Reg. at 64,673.
    EPA’s adoption of the Transfer-Based Exclusion and its
    conditions rests on the premise that materials sent to a
    reclamation facility to be stripped and reused or recycled are
    not part of the waste disposal problem targeted by Subtitle C
    regulations. Although “[h]azardous secondary materials stored
    or transported prior to recycling have the potential to present
    the same types of threats to human health and the environment
    as hazardous wastes stored or transported prior to disposal,” 
    id. at 64,671,
    EPA explained that “recycling of these materials
    often closely resembles industrial manufacturing rather than
    waste management,” 
    id. at 64,670.
    EPA also acknowledged
    that when hazardous secondary materials have negative rather
    than positive value (e.g., raw materials), reclaimers may
    respond differently than traditional manufacturers “to
    economic forces and incentives,” causing them to
    “accumulat[e] more inputs.” 
    Id. at 64,678.
    Responding to that concern, EPA adopted Transfer
    Conditions and Legitimacy Factors to ensure that, under the
    Transfer-Based Exclusion, materials may be sent only to
    reclaimers that have economic incentives to responsibly
    manage and recycle them. See 
    id. at 64,671;
    40 C.F.R.
    § 261.4(a)(24)(iv). Specifically, EPA addressed possible
    points of “discard,” whether unintended or surreptitious, during
    the transfer process. Although materials falling under the
    24
    Transfer-Based Exclusion need not comply with RCRA’s
    prescriptive containment requirements, see 40 C.F.R. § 262.17,
    the Transfer Conditions prohibit intermediate facilities from
    holding any material in storage for longer than 10 days, 
    id. § 261.4(a)(24)(ii),
    and therefore prohibit reclaimers from
    abandoning materials in warehouses or other facilities, see
    2008 Rule, 73 Fed. Reg. at 64,673. Generators, intermediate
    facilities, and reclaimers are required to maintain records of
    shipments and receipts of hazardous secondary materials, 40
    C.F.R. § 261.4(a)(24)(v)(D)–(E), (vi)(A)–(C), in order to
    enable EPA and the states to determine that materials “arrived
    at the intended facility and were not discarded in transit,” 2008
    Rule, 73 Fed. Reg. at 64,679. The Transfer Conditions also
    require a reclamation facility to reclaim at least 75% of
    hazardous secondary materials it obtains over a calendar year,
    see 40 C.F.R. § 261.4(a)(24)(i); 
    id. § 261.1(c)(8),
    as a means of
    ensuring reclaimers fulfill their role of facilitating resource
    conservation and preventing hazardous materials from entering
    landfills or other facilities, see 2008 Rule, 73 Fed. Reg. at
    64,685. The reclaimer must manage the material in a manner
    at least as protective as it handles analogous raw material. 40
    C.F.R. § 261.4(a)(24)(vi)(D).         Any residual materials
    generated by reclamation operations must be regulated under
    RCRA, including under Subtitle C if they are “discarded,” 
    id. § 261.4(a)(24)(vi)(E),
    so reclamation does not become a means
    of “discard” of unwanted material without complying with
    Subtitle C regulations, see 2008 Rule, 73 Fed. Reg. at 64,691.
    Enforcement mechanisms can also include imposition of
    Subtitle C requirements upon noncompliance with these
    conditions. See

    The Transfer Conditions thereby advance RCRA’s
    objectives by encouraging properly conducted recycling and
    promoting preservation of limited material resources and space
    for storing “solid waste.” Absent a statutory requirement that
    25
    these conditions be identical to Subtitle C requirements, EPA’s
    response was not arbitrary and capricious.
    B.
    EPA has also adequately addressed why it considers the
    Transfer-Based Exclusion’s conditions sufficient when it had
    expressed concern they might not be implemented as expected.
    Pet’rs’ Br. 44 (citing 2015 Rule, 80 Fed. Reg. at 1707–08).
    Although EPA had previously questioned the adequacy of
    the Transfer Conditions, the circumstances of recycling by the
    time EPA issued the Transfer-Based Exclusion in 2008 were
    different than the recycling landscape dating back to the 1980s
    that EPA’s environmental problems study had examined. See
    2015 Rule, 80 Fed. Reg. at 1708–09. Industry pointed to
    evidence of improved recycling management and controls over
    time in response to the rigor of enforcement efforts and
    industry’s interest in avoiding costly Subtitle C requirements
    by properly recycling or reusing materials. See 2008 Rule, 73
    Fed. Reg. at 64,673.
    Agreeing the environmental problems highlighted in the
    study “demonstrate[d] the need” for “restrictions and
    conditions for the exclusions,” 
    id. at 64,722–23,
    EPA proposed
    requirements for financial assurance, reasonable efforts,
    shipping documentation, hazardous secondary materials
    management, legitimate recycling, and speculative
    accumulation that became part of the Transfer Conditions.
    EPA’s study of successful recycling had shown that
    “generators who could otherwise bear a large liability from
    poorly-managed recycling at other companies have addressed
    [these] issue[s] by carefully examining the recyclers to which
    they send their hazardous secondary materials, such as through
    audits to ensure that they are technically and financially
    capable of performing the recycling.” 2015 Rule, 80 Fed. Reg.
    26
    at 1699. Based on best practices many industry facilities were
    already implementing with success in preventing discard and
    curbing environmental and health risks, 2008 Rule, 73 Fed.
    Reg. at 64,673–74, 64,683, EPA adopted restrictions and
    conditions that it determined were “sufficient to ensure safe
    recycling activities,” 
    id. at 64,722.
    Accordingly, we deny the petition. Under this court’s
    precedent EPA did not exceed its authority under RCRA in
    adopting the Transfer-Based Exclusion because hazardous
    secondary materials are not necessarily “discarded” each time
    they are transferred from a generator to a reclaimer along with
    payment. EPA has also adequately explained why such
    materials may be subject to the Transfer Conditions rather than
    full Subtitle C requirements.
