    SUMMARY**
    Environmental Law
    The panel affirmed in part and reversed in part the district
    court’s order approving consent decrees in an action under
    the Comprehensive Environmental Response Compensation
    and Liability Act.
    The panel reaffirmed that a district court has an obligation
    to independently scrutinize the terms of CERCLA consent
    decrees by, among other things, comparing the proportion of
    total projected costs to be paid by the settling parties with the
    proportion of liability attributable to them. The panel
    concluded that the district court properly declined to issue
    declaratory relief regarding intervening parties’ future
    CERCLA liability because the intervenors did not request
    such relief in their complaints. The panel further held that the
    district court erred in entering the parties’ proposed CERCLA

    consent decrees, because the court failed to independently
    scrutinize the terms of the agreements, and in so doing,
    afforded undue deference to the Arizona Department of
    Environmental Quality.
    Judge Callahan concurred in part and dissented in part.
    She agreed with Part I of the majority’s decision where it
    concluded that the district court properly denied the
    intervenors’ request for declaratory relief. She dissented
    from Part II of the majority’s decision because she would
    conclude that the district court properly approved the
    proposed consent decrees.

    6               ARIZONA V. RAYTHEON CO.
    OPINION
    M. SMITH, Circuit Judge:
    In this appeal, we address a district court’s obligation to
    scrutinize the terms of a proposed consent decree under the
    Comprehensive Environmental Response Compensation and
    Liability Act, 42 U.S.C. § 9601–75 (CERCLA). In so doing,
    we reaffirm that a district court has an “obligation to
    independently scrutinize the terms of [such agreements],” by,
    inter alia, comparing “the proportion of total projected costs
    to be paid by the [settling parties] with the proportion of
    liability attributable to them.” United States v. Montrose
    Chem. Corp. of Cal., 
    50 F.3d 741
    , 747 (9th Cir. 1995)
    (internal quotation marks and emphasis omitted).
    We conclude that the district court properly declined to
    issue declaratory relief regarding the intervening parties’
    (Intervenors) future CERCLA liability. We further hold that
    the district court erred in entering the parties’ proposed
    CERCLA consent decrees, because the court failed to
    independently scrutinize the terms of the agreements, and in
    so doing, afforded undue deference to the Arizona
    Department of Environmental Quality (ADEQ). We therefore
    affirm in part, reverse in part, and remand for further
    proceedings.
    FACTUAL AND PROCEDURAL BACKGROUND
    This case concerns liability under CERCLA and its state
    law counterpart, the Arizona Water Quality Assurance
    Revolving Funds (WQARF), A.R.S. § 49-281–391, for
    cleanup costs resulting from the contamination of the
    ARIZONA V. RAYTHEON CO.                      7
    Broadway-Patano Landfill Site (the Site)—a hazardous waste
    site in Tucson, Arizona.
    In January 2009, following an extensive investigation by
    the ADEQ, the State of Arizona filed a petition in the United
    States District Court for the District of Arizona, seeking to
    preserve the testimony of Ernest Joseph Blankinship—an
    elderly witness who had extensive knowledge of the Site’s
    contamination. During the course of the proceedings, several
    parties, who were potentially responsible for the Site’s
    contamination (i.e., potentially responsible parties),
    approached the State seeking to enter into early settlement
    agreements, releasing them from additional liability under
    CERCLA and WQARF.
    On June 18, 2010, the State sent early settlement offers to
    those parties who requested early agreements, and the State
    ultimately reached eighteen proposed agreements with
    twenty-two parties. The proposed agreements require the
    settling parties to pay specified damages to the State, in
    exchange for a full release of liability under CERCLA and
    WQARF. Consistent with Section 113(f)(2) of CERCLA, the
    proposed agreements further release the settling parties from
    any obligation to pay contribution to non-settling parties in
    the future. See 42 U.S.C. § 9613(f)(2).
    In order to obtain judicial approval of the proposed
    agreements under 42 U.S.C. § 9613(f)(2), the State initiated
    this action against the settling parties (Defendants-Appellees),
    alleging liability for the Site’s cleanup under CERCLA and
    WQARF. Shortly thereafter, the State filed public notice of
    its intent to enter into consent decrees with the Defendants-
    Appellees. A number of non-settling parties filed comments
    8                   ARIZONA V. RAYTHEON CO.
    objecting to the proposed consent decrees and the State filed
    responses.
    On March 11, 2011, the State filed a motion to enter the
    consent decrees. The State’s motion explained that the total
    estimated cost of remediation was $75 million, and that the
    State calculated the liability of the settling parties to be de
    minimis—0.01% to 0.2% of the total cost. Several potentially
    responsible parties, who were not parties to the settlements,
    subsequently moved to intervene in the action.1 The district
    court granted these motions over the State’s objection.2
    1
    The State informed Intervenors that the State considered them to be
    potentially responsible parties for contamination at the Site. The State sent
    each Intervenor a settlement offer, but Intervenors rejected these
    agreements.
    2
    After granting the motions to intervene, the court ordered the parties
    to brief whether additional discovery was necessary prior to the court’s
    ruling on the State’s motion to enter consent decrees. The State took the
    position that additional discovery was not necessary. Intervenors
    disagreed. The court ultimately declined to order formal discovery, but
    instead ordered the State to supplement its motion to enter consent decrees
    with “additional information regarding the [] formula/methodology used
    to calculate settlement amounts.” On appeal, Intervenors challenge the
    district court’s order denying formal discovery.
    “[B]road discretion is vested in the trial court to permit or deny
    discovery, and its decision to deny discovery will not be disturbed except
    upon the clearest showing that denial of discovery results in actual and
    substantial prejudice to the complaining litigant.” Hallett v. Morgan,
    
    296 F.3d 732
    , 751 (9th Cir. 2002) (internal quotation marks omitted).
    Here, the district court did not abuse its discretion in ordering the State to
    provide additional information through supplemental briefing, in lieu of
    ordering formal discovery.
    ARIZONA V. RAYTHEON CO.                               9
    Intervenors opposed the State’s motion to enter the
    consent decrees. In so doing, they primarily argued that the
    State did not provide sufficient information for the parties or
    the court to determine whether the consent decrees were
    substantively “fair, reasonable, and consistent with
    CERCLA’s objectives.” 
    Montrose, 50 F.3d at 748
    .
    Intervenors’ brief in opposition to the motion further
    requested a court order declaring that the State could not, in
    the future, hold Intervenors jointly and severally liable for
    costs related to the Site’s cleanup.3
    The district court denied Intervenors’ request for
    declaratory relief and issued a twelve-page opinion approving
    the consent decrees. The district court’s opinion lays out the
    procedural background of this case and the legal framework
    under which proposed CERCLA consent decrees are
    reviewed. Although the district court recognized its obligation
    to independently scrutinize the terms of the settlements, the
    district court did not engage in a substantive analysis of the
    settlements’ terms. In approving the consent decrees, the
    court declined to even discuss the parties’ individual or
    aggregate settlement amounts, and merely deferred to the
    ADEQ’s judgment that “the public interest is best served
    through entry of th[e] agreement[s].” Intervenors timely
    appealed.
    3
    Throughout this litigation, the State has asserted that WQARF
    prohibits the State from holding Intervenors jointly and severally liable in
    future litigation. CERCLA contains no such limitation. See Burlington N.
    & Santa Fe Ry. Co. v. United States, 
    556 U.S. 599
    , 614 (2009) (liability
    under CERCLA is generally joint and several).
    10               ARIZONA V. RAYTHEON CO.
    JURISDICTION AND STANDARD OF REVIEW
    We have jurisdiction under 28 U.S.C. § 1291. We review
    a district court’s grant or denial of declaratory relief for abuse
    of discretion. Cal. Ass’n of Rural Health Clinics v. Douglas,
    
    738 F.3d 1007
    , 1011 (9th Cir. 2013). We also review the
    approval of a consent decree for abuse of discretion. Turtle
    Island Restoration Network v. U.S. Dep’t of Commerce, 
    672 F.3d 1160
    , 1165 (9th Cir. 2012) (citing 
    Montrose, 50 F.3d at 746
    ). For the following reasons, we affirm in part, vacate in
    part, and remand.
    DISCUSSION
    I. The District Court Properly Denied Intervenors’
    Request for Declaratory Relief
    We affirm the district court’s order denying Intervenors’
    request for declaratory relief, because this request was not
    properly before the district court.
    Under the Declaratory Judgment Act, 28 U.S.C.
    §§ 2201–02, “any court of the United States, upon the filing
    of an appropriate pleading, may declare the rights and other
    legal relations of any interested party seeking such
    declaration . . . .” 28 U.S.C. § 2201.
    A request for declaratory relief is properly before the
    court when it is pleaded in a complaint for declaratory
    judgment. Kam-Ko Bio-Pharm Trading Co. Ltd-Australasia
    v. Mayne Pharma (USA) Inc., 
    560 F.3d 935
    , 943 (9th Cir.
    2009). Requests for declaratory judgment are not properly
    before the court if raised only in passing, or by motion. 
    Id. (denying “motion
    for declaratory judgment” because such a
    ARIZONA V. RAYTHEON CO.                     11
    motion is “inconsistent with the Federal Rules” (internal
    quotations marks omitted)).
    Here, Intervenors’ request for declaratory relief was not
    properly before the district court. Intervenors did not request
    this relief in their complaints. Rather, they requested an order
    regarding their future liability in their brief opposing the
    State’s motion to enter the consent decrees. If Intervenors
    wish to obtain a declaratory judgment, they must either file a
    separate action seeking such relief, or move to amend their
    complaints on remand. 
    Id. II. The
    District Court Erred in Entering the Consent
    Decrees
    We vacate and remand the district court’s order approving
    the consent decrees, because the court failed to independently
    scrutinize the terms of the agreements, see 
    Montrose, 50 F.3d at 747
    –48, and in so doing, afforded undue deference to the
    ADEQ.
    A. Legal Standard
    1. CERCLA
    “CERCLA is a comprehensive statute that [among other
    things] grants the President broad power to command
    government agencies and private parties to clean up
    hazardous waste sites.” Key Tronic Corp. v. United States,
    
    511 U.S. 809
    , 814 (1994). We have explained:
    [T]he Federal Government may clean up a
    contaminated area itself . . . or it may [seek an
    injunction to] compel responsible parties to
    12               ARIZONA V. RAYTHEON CO.
    perform the cleanup . . . . Under the first
    option . . . the government pays for the
    cleanup [using Superfund money] under
    § 9604 and then seeks recovery for its costs
    from [potentially responsible parties] under
    § 9607. This option has an obvious drawback
    for the government: It must pay first and sue
    for recovery of costs later (often in protracted
    litigation). The second option—compelling
    [potentially responsible parties] to perform the
    cleanup—therefore has its advantages.
    City of Rialto v. W. Coast Loading Corp., 
    581 F.3d 865
    , 869
    (9th Cir. 2009) (internal quotations and citations omitted).
    CERCLA also encourages states, localities, and private
    parties to assist in the cleanup of hazardous waste sites.
    Under Section 104, a state may enter into a contract with the
    Environmental Protection Agency (EPA), pursuant to which
    both the state and the EPA engage in cleanup efforts on a
    cost-sharing basis. 42 U.S.C. § 9604(c), (d). A state may also
    independently engage in CERCLA remediation efforts, so
    long as those efforts are not inconsistent with the EPA’s
    National Contingency Plan. See New York v. Shore Realty
    Corp., 
    759 F.2d 1032
    , 1047–48 (2d Cir. 1985).
    CERCLA imposes strict liability on certain classes of
    parties who are potentially responsible for a site’s
    contamination. 
    Burlington, 556 U.S. at 608
    ; Anderson Bros.,
    Inc. v. St. Paul Fire and Marine Ins. Co., 
    729 F.3d 923
    , 929
    (9th Cir. 2013). Under Section 107(a), the federal government
    or a state can sue responsible parties for “all costs of removal
    or remedial action incurred by the United States Government
    ARIZONA V. RAYTHEON CO.                             13
    or a State . . . not inconsistent with the [EPA’s] [N]ational
    [C]ontingency [P]lan.” 42 U.S.C. § 9607(a)(4)(A).4
    CERCLA liability is generally joint and several, see
    
    Anderson, 729 F.3d at 926
    , 930, and a defendant seeking to
    avoid joint and several liability “bear[s] the burden of proving
    that a reasonable basis for apportionment exists,” 
    Burlington, 556 U.S. at 614
    . A defendant who is held jointly and
    severally liable under Section 107 may, however, seek
    contribution from other responsible parties under Section
    113(f)(1). 42 U.S.C. § 9613(f)(1); Cooper Indus., Inc. v.
    Aviall Servs., Inc., 
    543 U.S. 157
    , 162–63 (2004).
    2. Early Settlements
    “Congress sought through CERCLA . . . to encourage
    settlements that would reduce the inefficient expenditure of
    public funds on lengthy litigation.” Chubb Custom Ins. Co. v.
    Space Sys./Loral, Inc., 
    710 F.3d 946
    , 971 (9th Cir. 2013)
    (quoting In re Cuyahoga Equip. Corp., 
    980 F.2d 110
    , 119 (2d
    Cir. 1992)). Consistent with this objective, Section 113(f)(2)
    provides that a party who has resolved its CERCLA liability
    through a judicially approved consent decree “shall not be
    liable [to other responsible parties] for claims for contribution
    4
    The state need not obtain EPA authorization to engage in CERCLA
    remediation efforts and to recover costs under Section 107. Shore 
    Realty, 759 F.2d at 1047
    –48 (“[W]e reject [the] argument that the State’s response
    costs are not recoverable because the State has failed to . . . obtain[] EPA
    authorization . . . . Congress envisioned states’ using their own resources
    for cleanup and recovering those costs from polluters under section
    9607(a)(4)(A). We read section 9607(a)(4)(A)’s requirement of
    consistency with the [National Contingency Plan] to mean that states
    cannot recover costs inconsistent with the response methods outlined in
    the [EPA’s National Contingency Plan].”).
    14              ARIZONA V. RAYTHEON CO.
    regarding matters addressed in the settlement.” 42 U.S.C.
    § 9613(f)(2). This statutory framework contemplates that
    potentially responsible parties who do not enter into early
    settlement agreements may ultimately bear a disproportionate
    share of the CERCLA liability. For this reason, potentially
    responsible parties who do not enter into such agreements
    have standing to intervene in CERCLA actions to oppose the
    entry of CERCLA consent decrees. United States v. Aerojet
    Gen. Corp., 
    606 F.3d 1142
    , 1150–53 (9th Cir. 2010).
    3. Standard of Review
    In order to approve a CERCLA consent decree, a district
    court must conclude that the agreement is procedurally and
    substantively “fair, reasonable, and consistent with
    CERCLA’s objectives.” 
    Montrose, 50 F.3d at 748
    . “Fair” and
    “reasonable” are comparative terms. 
    Id. at 747.
    Thus, in order
    to approve a CERCLA consent decree, a district court must
    find that the agreement is “based upon, and roughly
    correlated with, some acceptable measure of comparative
    fault, apportioning liability among the settling parties
    according to rational (if necessarily imprecise) estimates of
    how much harm each [potentially responsible party] has
    done.” United States v. Charter Int’l Oil Co., 
    83 F.3d 510
    ,
    521 (1st Cir. 1996) (quoting United States v. Cannons Eng’g
    Corp., 
    899 F.2d 79
    , 87 (1st Cir. 1990)).
    In approving a CERCLA consent decree, the district court
    has an “obligation to independently scrutinize the terms of
    [the agreement].” 
    Montrose, 50 F.3d at 747
    (internal
    quotation marks omitted). In so doing, the court must “gauge
    the adequacy of settlement amounts to be paid by settling
    [parties by comparing] the proportion of total projected costs
    to be paid by the settlors with the proportion of liability
    ARIZONA V. RAYTHEON CO.                      15
    attributable to them, and then . . . factor into the equation any
    reasonable discount for litigation risks, time savings, and the
    like . . . .” 
    Id. (emphasis omitted);
    Charter Int’l 
    Oil, 83 F.3d at 515
    (holding that the district court’s assessment must
    include “an appraisal of what the government is being given
    by the [settling party] relative to what the [settling party] is
    receiving”). A district court abuses its discretion where it
    does not fulfill its obligation to engage in this comparative
    analysis. 
    Montrose, 50 F.3d at 746
    –47.
    We have further explained that the district court’s review
    of a CERCLA consent decree may not be made in an
    “informational vacuum,” or where the record contains “no
    evidence at all on an important point.” 
    Id. But, the
    mere fact
    that evidence sufficient to evaluate the terms of an agreement
    is either before the court or purportedly in the parties’
    possession is not alone sufficient. The district court must
    actually engage with that information and explain in a
    reasoned disposition why the evidence indicates that the
    consent decrees are procedurally and substantively “fair,
    reasonable, and consistent with CERCLA’s objectives.” 
    Id. at 748.
    As we have explained in other contexts: “Without
    some indication or explanation of how the district court
    arrived at [its conclusion], it is simply not possible for this
    court to review [the district court’s determination] in a
    meaningful manner,” and we have no way of knowing
    whether the district court abused its discretion. Padgett v.
    Loventhal, 
    706 F.3d 1205
    , 1208 (9th Cir. 2013) (internal
    quotation marks omitted).
    B. Application
    Although the district court recognized its obligation to
    independently scrutinize the settlements, “[a]cknowledging
    16               ARIZONA V. RAYTHEON CO.
    that obligation and fulfilling it . . . are two different things.”
    
    Montrose, 50 F.3d at 746
    . And here, the district court failed
    to adequately review the agreements.
    Montrose requires that the district court “gauge the
    adequacy of settlement amounts to be paid by settling
    [parties]” by engaging in a comparative analysis. 
    Id. at 747.
    But nowhere in the district court’s opinion is there an analysis
    comparing each party’s estimated liability with its settlement
    amount, or an explanation of why the settlements are “fair,
    reasonable, and consistent with CERCLA’s objectives.” 
    Id. at 748.
    The court’s entire numerical analysis is found in a
    single footnote, which provides: “The State’s analysis
    indicates that, based upon a preliminary estimate of remedial
    action costs of $75 Million, the range of liability for each
    settling party extended from 0.01% of the estimated total
    clean up costs to 0.2%, or as expressed in dollar figures, from
    $10,000.00 to $150,750.00.” The opinion goes on to
    acknowledge, however, that the State did not provide any
    evidence supporting this estimated liability, or even
    “information from which the [district court could] confirm
    that the settling parties are [in fact] de minimis contributors.”
    The opinion even fails to mention the parties’ individual or
    aggregate settlement amounts.
    Rather than engaging in the analysis that Montrose
    requires, the district court merely accepted the State’s
    representation that the settlements were substantively fair and
    reasonable because: “[t]he State . . . informed the Court of the
    factual bases (files, interviews, documents) for its conclusions
    . . . [and] explained the methods (software, past costs,
    estimates) to reach remediation costs.” In so doing, the court
    did not fulfill its responsibilities to independently assess the
    ARIZONA V. RAYTHEON CO.                             17
    adequacy of the agreements and to provide a reasoned
    explanation for its decision.
    In declining to substantively engage with the parties’
    proposed agreements, the district court further explained that
    “review of the specific evidence relating to each party would
    require [the district court] to conduct an in-depth review of
    the evidence, second guess the agency, and deny the required
    deference to [the] ADEQ.” According to the district court, it
    must defer to the ADEQ’s judgment “unless it is arbitrary,
    capricious, and devoid of any rational basis.”5
    As the First Circuit has observed, “almost all of the law
    regarding approval of CERCLA consent decrees comes from
    cases in which the [EPA is] a party.” City of Bangor v.
    Citizens Commc’ns Co., 
    532 F.3d 70
    , 89 (1st Cir. 2008). In
    such cases, the approval of a CERCLA consent decree
    “reaches the appellate level ‘encased in a double layer of
    swaddling.’” 
    Montrose, 50 F.3d at 746
    (quoting 
    Cannons, 899 F.2d at 84
    ); see also United States. v. George A. Whiting
    Paper Co., 
    644 F.3d 368
    , 372 (7th Cir. 2011). The first layer
    of swaddling requires the district court to “refrain from
    second-guessing the Executive” and to defer to the EPA’s
    expertise. 
    Montrose, 50 F.3d at 746
    (quoting Cannons,
    5
    The State argues that under 42 U.S.C. § 9607(f)(2)(C) the State’s
    judgment is entitled to a “rebuttable presumption of correctness.” But this
    “presumption of correctness” specifically applies to an appointed trustee’s
    natural resource damage assessment that is performed pursuant to the
    procedures set out in 42 U.S.C. § 9651(c). No such assessment is at issue
    here.

    The deference we owe to a federal agency’s administration of statutes
    it is charged with enforcing varies with the circumstances. United States
    v. Mead Corp., 
    533 U.S. 218
    , 227–28 (2001). While the courts of appeals
    agree that the EPA is afforded significant deference when it seeks judicial
    approval of a proposed CERCLA consent decree, courts have not
    established whether the deference that we afford the EPA is the deference
    described in Chevron U.S.A., Inc. v. Natural Resources Defense Council,
    Inc., 
    467 U.S. 837
    (1984), the deference described in Skidmore v. Swift &
    Co., 
    323 U.S. 134
    (1944), or some other type of deference.
    7
    Our dissenting colleague faults us for discussing deference and
    suggests that the issue of whether the district court abused its discretion
    in approving the consent decrees can be separated from “[the] different
    issue” of the degree to which a district court ought to defer to a state’s
    decision to enter into an early settlement under CERCLA. While these two
    issues may be “different,” they are inextricably intertwined. We cannot
    decide whether a judge abused her discretion in approving a consent
    decree without deciding what degree of deference is owed to the party
    proposing the agreement. This is so because the threshold issue in
    deciding whether a district court abused its discretion is whether the
    district court “identified the correct legal rule to apply to the relief
    requested.” Perry v. Brown, 
    667 F.3d 1078
    , 1084 (9th Cir. 2012) (internal
    quotation marks omitted). For this reason, if the district court applied the
    wrong deferential standard of review in assessing the consent decrees, we
    must hold that the court abused its discretion for that reason alone.
    ARIZONA V. RAYTHEON CO.                     19
    adopted the First Circuit’s “double-swaddling” test to review
    CERCLA consent decrees sponsored by the EPA.
    Nonetheless, we declined to apply or discuss this test in
    Arizona v. Components Inc., 
    66 F.3d 213
    , 215 (9th Cir. 1995),
    a case involving a state sponsored CERCLA settlement,
    which we decided just six months after Montrose. In
    Components, we merely held that there was sufficient
    evidence before the district court for it to review the state-
    sponsored consent decree and that the district court properly
    reviewed that evidence. 
    Id. at 216–17.
    We declined to discuss
    what, if any deference, was owed to the state agency’s
    interpretation of CERCLA.
    The First Circuit has similarly declined to apply its
    “double-swaddling” standard to CERCLA consent decrees
    sponsored by state agencies. In Bangor, the First Circuit held:
    Federal courts generally defer to a state
    agency’s interpretation of those statutes it is
    charged with enforcing, but not to its
    interpretation of federal statutes it is not
    charged with enforcing.
    We choose to accord some deference to [the
    state’s] decision to sign onto the [c]onsent
    [d]ecree, but not the same amount of
    deference we would accord the EPA in a
    consent decree involving the United States.
    We give deference in recognition that the state
    agency has some expertise. This lesser
    deference does not displace the baseline
    standard of review for abuse of discretion.
    
    Bangor, 532 F.3d at 94
    (internal citations omitted).
    20                   ARIZONA V. RAYTHEON CO.
    We find the reasoning of the First Circuit on this issue
    persuasive, and we hold that where state agencies have
    environmental expertise they are entitled to “some deference”
    with regard to questions concerning their area of expertise.
    But “[a] state agency’s interpretation of federal statutes is not
    entitled to the deference afforded [to] a federal agency’s
    interpretation of . . . statutes” that it is charged with
    enforcing. Orthopaedic Hosp. v. Belshe, 
    103 F.3d 1491
    , 1495
    (9th Cir. 1997) (emphasis added); see also 
    Bangor, 532 F.3d at 94
    . Applying these principles, if the district court finds that
    the ADEQ has expertise concerning the cleanup of the Site,
    it may afford “some deference” to the ADEQ’s judgment
    concerning the environmental issues underlying the CERCLA
    consent decrees at issue in this case.8 The ADEQ is not
    entitled to deference, however, concerning its interpretation
    of CERCLA’s mandate. Nor may the district court abdicate
    its responsibility to independently determine that the
    agreements are “fair, reasonable, and consistent with
    CERCLA’s objectives,” 
    Montrose, 50 F.3d at 748
    , by
    deferring to the ADEQ’s judgment that the agreements satisfy
    Montrose.9
    8
    State agencies, including those charged with enforcing environmental
    laws, may vary from state to state in terms of their competence, their
    resources, and their philosophies concerning the enforcement of
    environmental laws. These considerations are ones that a district judge
    may properly take into account in assessing the deference owed to an
    agency’s expertise.
    9
    The dissent concedes that whether a particular agreement is “fair,
    reasonable, and consistent with CERCLA’s objectives,” 
    Montrose, 50 F.3d at 748
    , “may present questions of statutory interpretation.” See
    Orthopaedic 
    Hosp., 103 F.3d at 1495
    –96 (“[a] state agency’s
    interpretation of federal statutes is not entitled to the deference afforded
    [to] a federal agency’s interpretation of . . . statutes” that it is charged with
    enforcing).

    CONCLUSION
    Even if the EPA had been a party to the proposed consent
    decrees in this case, the district court would have failed to
    fulfill its duty to independently scrutinize the parties’
    agreements, as required by Montrose. That error is
    compounded where, as here, the court deferred completely to
    a state agency’s judgment that the proposed agreements were
    fair, reasonable, and consistent with federal law. See 
    id. For these
    reasons, we vacate the district court’s order
    entering the consent decrees, and we remand for the court to
    reconsider the agreements under the principles set forth in
    this opinion. In reaching this conclusion, we express no
    opinion as to whether the consent decrees at issue in this case
    ought to be affirmed on remand, after the district court has
    fulfilled the responsibilities discussed in this opinion.10

    REMANDED.

    The dissent has undertaken a review of the record de novo, and,
    having done so, concludes that there is sufficient evidence in the record to
    approve the consent decrees. This is contrary to the law of our circuit. The
    decision of whether to approve consent decrees in the first instance is
    entrusted to the sound discretion of the district court, not to our court. For
    this reason, if a district court fails to engage in the appropriate analysis, we
    are required to remand for the district court to complete its work. See

    , 748.
    22              ARIZONA V. RAYTHEON CO.
    CALLAHAN, Circuit Judge, concurring, in part, and
    dissenting, in part:
    I agree with Part I of the majority’s decision where it
    concludes that the district court properly denied the
    intervening parties’ (“Intervenors”) request for declaratory
    relief and did not abuse its discretion in denying the
    Intervenors’ request for formal discovery. However, because
    I would conclude that the district court properly approved the
    proposed consent decrees, I dissent from Part II of the
    majority’s decision.
    The issue on appeal is whether the district court abused
    its discretion in approving consent decrees that the State
    of Arizona entered into with a number of potentially
    responsible parties (“PRPs”) under the Comprehensive
    Environmental Response, Compensation, and Liability Act
    (“CERCLA”), 42 U.S.C. §§ 9601–75. In the process of
    deciding that question, however, the majority raises and
    decides— incorrectly in my opinion—a different issue: the
    degree to which a district court ought to defer to a state’s
    decision to enter into an early settlement with PRPs under
    CERCLA. Although the majority recognizes that state
    agencies may have environmental expertise and be entitled to
    “some deference” with regard to “environmental issues,” it
    goes on to suggest that the states and their environmental
    agencies are entitled to no deference in their decisions to
    enter into early settlements with PRPs. In doing so, the
    majority fails to recognize the critical role that Congress
    envisioned for the states under CERCLA and expands the
    level of scrutiny required for state-sponsored CERCLA
    settlements. The majority’s decision is inconsistent with the
    principles that guide our review of consent decrees in general
    and the decisions of our sister circuits in this context. The
    ARIZONA V. RAYTHEON CO.                      23
    decision will ultimately make it more difficult for states to
    play the role that Congress envisioned for them in
    remediating the numerous polluted sites that blight our
    nation. Applying the proper level of deference in this case,
    I would hold that the district court did not abuse its discretion
    when it approved the consent decrees.
    I
    Arizona brought this action seeking remediation costs that
    it incurred and expected to incur under CERCLA, 42 U.S.C.
    § 9607(a), and Arizona’s parallel law, the Water Quality
    Assurance Revolving Fund (“WQARF”), Arizona Revised
    Statutes § 49-285. As the majority acknowledges, several
    PRPs approached Arizona early on during its investigation
    seeking to enter into settlements. Arizona sent early
    settlement offers to all PRPs. After reaching agreements with
    some of them, Arizona filed the present action and shortly
    thereafter, filed a motion seeking approval of the consent
    decrees.
    The district court subsequently ordered Arizona to
    supplement its motion. Arizona then submitted an affidavit
    with supporting materials from Ana I. Vargas, an Arizona
    Department of Environmental Quality (“ADEQ”) chemical
    engineer. Vargas explained that ADEQ relied on EPA
    guidelines that allocate responsibility by PRP category (i.e.,
    owner/operator, transporter, generator/arranger). Applying
    these guidelines, ADEQ reviewed the available information
    to come up with responsibility allocations for each PRP. For
    example, owners’ and operators’ allocations were largely
    based on length of ownership or operation, while generators’
    and transporters’ allocations were based primarily on volume.
    Thus, ADEQ allocated each generator a share of liability
    24              ARIZONA V. RAYTHEON CO.
    based on volume and other factors which was multiplied by
    0.60 (corresponding to the 60% allocation for
    generators/arrangers), which resulted in a final apportionment
    of liability for the generator. Vargas also provided a
    breakdown of ADEQ’s $75 million total cost estimate, of
    which, the settlements totaled $512,000. ADEQ then
    multiplied each PRP’s share of liability by the cost estimate
    to arrive at an individualized settlement offer for each PRP.
    Accordingly, under ADEQ’s formula, each settling defendant
    paid damages directly corresponding to ADEQ’s estimated
    apportionment of liability.
    The allocations were based upon ADEQ’s review of 800
    witness interviews and 100,000 pages of documents and its
    analysis of “information about the site to determine those
    areas about which it had no information.” Arizona provided
    that information to the Intervenors. Although Vargas did not
    specify how ADEQ arrived at each PRP’s specific allocation
    or settlement figure, she explained that ADEQ had proceeded
    in accord with EPA guidelines, which provide that “EPA will
    not provide a detailed explanation for the results due to the
    enforcement-sensitive nature of the discussions involved.”
    The Intervenors argued that Arizona had not supplied
    enough information for the court to approve the consent
    decrees because it had not specified what information it used
    to arrive at each PRP’s apportionment of liability or the cost
    calculation for each PRP. In its decision approving the
    consent decrees, the district court observed that courts “give
    deference to the government’s evaluation of” proposed
    consent decrees, citing Arizona ex rel. Woods v. Nucor Corp.,
    
    825 F. Supp. 1452
    , 1456 (D. Ariz. 1992), aff’d on other
    grounds sub nom. Arizona v. Components Inc., 
    66 F.3d 213
    ,
    215 (9th Cir. 1995). The court then reviewed the record, and
    ARIZONA V. RAYTHEON CO.                     25
    relying heavily on Vargas’s affidavit, determined that
    Arizona had provided sufficient information for it to evaluate
    the settlements. The district court noted: “The State’s
    analysis indicates that, based upon a preliminary estimate of
    remedial action costs of $75 Million, the range of liability for
    each settling party extended from 0.01% of the estimated
    total clean up costs to 0.2%, or as expressed in dollar figures,
    from $10,000.00 to $150,750.00.” The district court further
    explained:
    The State has informed the Court of the
    factual bases (files, interviews, documents)
    for its conclusions. It has explained the
    methods (software, past costs, estimates) to
    reach remediation costs. Although the Court
    agrees with Intervenors that the State has not
    provided the Court with specific factual
    details as to each settling party (e.g., witness
    N of the 800 witnesses stated that settling
    party X deposited a specified tonnage of a
    specified type of waste), such in-depth review
    of the facts and circumstances is not
    appropriate. Indeed, although Intervenors
    argue that such review is needed, Intervenors
    have not pointed to any controlling precedent
    that requires such in-depth review.
    The district court observed that it was not its “role to
    determine whether the settlement agreement is the best
    possible settlement that ADEQ could have achieved, but
    rather whether it is within the reaches of the public interest.”
    It concluded that the proposed consent decrees were
    reasonable and in the best interests of the public.
    26                  ARIZONA V. RAYTHEON CO.
    II
    The majority concludes that the district court applied the
    wrong level of deference to ADEQ’s judgment. It declares
    that “where state agencies have environmental expertise they
    are entitled to ‘some deference’ with regard to questions
    concerning their area of expertise.” However, it then
    concludes that the district court erred in deferring to ADEQ’s
    judgment that the agreements were “fair, reasonable, and
    consistent with CERCLA’s objectives.”1
    I cannot agree. Congress gave the states a critical role to
    play in CERCLA enforcement that will be severely
    undermined by the majority’s decision. Moreover, we defer
    to the EPA’s decision to settle with PRPs in light of: (a) our
    recognition of CERCLA’s policy of encouraging settlements;
    (b) recognition that the settlements are constructed by a party
    acting in the public interest; (c) respect for the EPA’s
    expertise; and (d) respect for an arms-length agreement.
    These considerations are equally applicable to state
    1
    I note that the parties did not raise the level of deference owed to
    ADEQ as a consequence of it being a state agency before the district court
    or on appeal. I would hold that the Intervenors forfeited any such
    argument by failing to raise it in their opening brief. See Avenetti v.
    Barnhart, 
    456 F.3d 1122
    , 1125 (9th Cir. 2006) (finding that the Social
    Security Commissioner waived an argument that deference applies to an
    administrative law judge’s interpretation of a disability listing by failing
    to argue it in his opening brief). The majority reaches this issue by
    proclaiming ipse dixit that it is “inextricably intertwined” with the “correct
    legal rule.” Curiously, although we were confronted with the same exact
    scenario in Arizona v. Components, 
    66 F.3d 213
    , 215 (9th Cir. 1995), we
    affirmed the district court. What the majority has really done is invented
    a new legal rule, retroactively evaluated the district court’s decision
    against it, and faulted the district court for failing to anticipate it.
    ARIZONA V. RAYTHEON CO.                            27
    environmental agencies, which accordingly are also entitled
    to significant deference.2
    A
    Congress enacted CERCLA “in response to the serious
    environmental and health risks posed by industrial pollution.”
    Burlington N. & Santa Fe Ry. Co. v. United States, 
    556 U.S. 599
    , 602 (2009). “The Act was designed to promote the
    timely cleanup of hazardous waste sites and to ensure that the
    costs of such cleanup efforts were borne by those responsible
    for the contamination.” 
    Id. (internal quotation
    marks
    omitted). CERCLA provides a number of powers to the
    President, who has delegated most of his authority to the
    EPA, “[t]o ensure the prompt cleanup of hazardous waste
    sites.” Pakootas v. Teck Cominco Metals, Ltd., 
    452 F.3d 1066
    , 1072 & n.11 (9th Cir. 2006).
    Although states do not have as large of a role as the EPA
    does in enforcing CERCLA, Congress envisioned a crucial
    role for the states in remediating hazardous waste sites. Most
    significantly, Congress provided that the various categories
    of PRPs “shall be liable for” certain remediation costs
    “incurred by the United States Government or a State or an
    Indian Tribe.” 42 U.S.C. § 9607(a) (emphasis added); see
    also Niagara Mohawk Power Corp. v. Chevron U.S.A., Inc.,
    
    596 F.3d 112
    , 120 (2d Cir. 2010) (“CERCLA empowers the
    federal government and the states to initiate comprehensive
    cleanups and to seek recovery of expenses associated with
    those cleanups.” (emphasis added)).
    2
    The importance of this issue is underscored by the fact that the States
    of Colorado and Nevada filed a letter brief supporting Arizona’s position
    less than one month after the issue was initially raised.
    28               ARIZONA V. RAYTHEON CO.
    Congress also envisioned that states would play a central
    role by enforcing CERCLA through early settlements. One
    of CERCLA’s central purposes is to encourage “early
    settlement between PRPs and environmental regulators.”
    Anderson Bros., Inc. v. St. Paul Fire & Marine Ins. Co.,
    
    729 F.3d 923
    , 929–30 (9th Cir. 2013) (citation and alteration
    marks omitted). PRPs have a strong incentive “to participate
    in settlement talks at the earliest possible opportunity because
    ‘non-settling PRPs may be held jointly and severally liable
    for the entire amount of response costs minus the amount of
    the settlement.’” 
    Id. at 930
    (citation and alteration marks
    omitted). This is because settlements provide settling parties
    with protection against contribution actions from other PRPs:
    A person who has resolved its liability to the
    United States or a State in an administrative
    or judicially approved settlement shall not be
    liable for claims for contribution regarding
    matters addressed in the settlement. Such
    settlement does not discharge any of the other
    potentially liable persons unless its terms so
    provide, but it reduces the potential liability of
    the others by the amount of the settlement.
    42 U.S.C. § 9613(f)(2) (emphasis added). Nonetheless, a
    settling PRP may still seek contribution from non-settling
    PRPs. § 9613(f)(3)(B). Thus, as the First Circuit has
    observed: “Congress has . . . recognized a special role for
    states in authorizing judicial approval for consent decrees in
    which the state is a party, and then authorizing both
    contribution protection and contribution claims.” City of
    Bangor v. Citizens Commc’ns Co., 
    532 F.3d 70
    , 90 (1st Cir.
    2008). States can therefore act independently to definitely
    ARIZONA V. RAYTHEON CO.                            29

    Indeed, the EPA itself has recognized that “because of the
    number and variety of contaminated sites across the country,
    states play a critical role in effectuating the purposes of
    CERCLA.” 
    Id. at 126
    (alteration marks omitted) (quoting the
    EPA’s amicus brief). The EPA has elaborated:
    When Congress first enacted [CERCLA] in
    1980, it required States to be active partners in
    conducting Superfund response actions. . . .
    CERCLA, as amended, strengthens the
    partnership between the Federal Government
    and State and local authorities. State and
    local governments play an important role in
    ensuring effective, efficient and well-
    coordinated cleanups.
    EPA, Pub. No. 9375.5-01/FS, State and Local Involvement In
    the Superfund Program (1989).
    As a practical matter, state participation in CERCLA
    enforcement is absolutely necessary because there are more
    contaminated sites than the EPA is capable of addressing on
    3
    CERCLA also provides special roles for states in other contexts, such
    as allowing them to pursue claims for damages to their natural resources.
    See § 9607(f). States are also “given a special role in defining allowable
    costs and cleanup standards.” City of 
    Bangor, 532 F.3d at 91
    .
    Specifically, state remediation efforts are presumed to be consistent with
    the “national contingency plan,” which consists of EPA “procedures for
    preparing and responding to contaminations.”

    also gives states the authority to enforce any applicable state or federal
    standard.

    its own. As several commentators have explained, under
    CERCLA:
    the role of the States at national priorities list
    (NPL) sites ranges from required cost sharing
    at federally funded cleanups to active site
    management. A vast number of contaminated
    sites do not meet the criteria for inclusion on
    the NPL. For these non-NPL sites the federal
    government’s role is likely to be limited to
    site assessment and emergency response or
    removal activities. For many non-NPL sites,
    the federal government may not be involved
    at all. Thus, if any government-supervised
    activity is to occur at non-NPL sites, States
    will have to oversee, enforce, or fund
    cleanups. For these reasons, the role of the
    States in addressing contaminated sites,
    independently and in concert with the federal
    government, has become increasingly
    important.

    Indeed, there are an estimated 450,000 contaminated sites
    in the nation. See Ronald G. Aronovsky, A Preemption

    the EPA’s national priorities list. See U.S. Environmental
    Protection Agency, National Priorities List (NPL),

    (“The federal government, through
    the . . . EPA[], plays an active regulatory role at only a small
    percentage of the nation’s contaminated sites. Instead, a state
    or local government agency serves as the lead regulatory
    authority at the vast majority of sites.”).            Practical
    considerations also preclude states from proceeding solely
    under state law. Although many states—like Arizona—have
    their own parallel laws, settling parties, desiring greater
    certainty, will insist on CERCLA contribution protection and
    judicial approval.4

    The seminal decision on CERCLA consent decrees is

    Cir. 1990). Drawing on the legislative history of § 9613, the
    First Circuit concluded that, when evaluating consent decrees,
    “the trial court’s review function is only to ‘satisfy itself that
    the settlement is reasonable, fair, and consistent with the
    purposes that CERCLA is intended to serve.’”5 
    Id. at 85

    in 1986 U.S.C.C.A.N. 3038, 3042). Thus, the First Circuit
    determined that district courts should evaluate consent
    decrees according to their fairness, reasonableness, and
    fidelity to the statute. 
    Id. at 85
    –90. As that court
    subsequently observed, these factors are “similar to the one[s]
    used by courts when reviewing consent decrees generally.”
    City of 
    Bangor, 532 F.3d at 93
    . We are in accord. See Turtle
    Island Restoration Network v. U.S. Dep’t of Commerce,
    
    672 F.3d 1160
    , 1165 (9th Cir. 2012) (“A district court may
    approve a consent decree when the decree is ‘fair, reasonable
    and equitable and does not violate the law or public policy.’”
    (citation omitted)).
    In Cannons, the First Circuit further observed that:
    We approach our task mindful that, on
    appeal, a district court’s approval of a consent
    decree in CERCLA litigation is encased in a
    double layer of swaddling. In the first place,
    it is the policy of the law to encourage
    5
    As is relevant here, the courts’ judicial review function originates with
    42 U.S.C. § 9613(f)(2). CERCLA separately sets forth procedures—
    including judicial approval—for settlements between the United States
    and private parties under § 9622, which do not apply here. See City of
    
    Bangor, 532 F.3d at 93
    . Notably, § 9613(f)(2) refers to “an administrative
    or judicially approved settlement,” indicating that administrative
    approval is sufficient to provide contribution protection to PRPs settling
    with state agencies.
    ARIZONA V. RAYTHEON CO.                   33
    settlements. That policy has particular force
    where, as here, a government actor committed
    to the protection of the public interest has
    pulled the laboring oar in constructing the
    proposed settlement. While “the true measure
    of the deference due depends on the
    persuasive power of the agency’s proposal
    and rationale, given whatever practical
    considerations may impinge and the full
    panoply of the attendant circumstances,” the
    district court must refrain from second-
    guessing the Executive Branch.
    Respect for the agency’s role is
    heightened in a situation where the cards have
    been dealt face up and a crew of sophisticated
    players, with sharply conflicting interests, sit
    at the table. That so many affected parties,
    themselves knowledgeable and represented by
    experienced lawyers, have hammered out an
    agreement at arm’s length and advocate its
    embodiment in a judicial decree, itself
    deserves weight in the ensuing balance. The
    relevant standard, after all, is not whether the
    settlement is one which the court itself might
    have fashioned, or considers as ideal, but
    whether the proposed decree is fair,
    reasonable, and faithful to the objectives of
    the governing statute. Thus, the first layer of
    insulation implicates the trial court’s
    deference to the agency’s expertise and to the
    parties’ agreement. While the district court
    should not mechanistically rubberstamp the
    agency’s suggestions, neither should it
    34              ARIZONA V. RAYTHEON CO.
    approach the merits of the contemplated
    settlement de 
    novo. 899 F.2d at 84
    (citations omitted). Thus, the First Circuit’s
    rationale for deferring to the EPA rested on: (a) CERCLA’s
    policy of encouraging settlements; (b) its recognition that the
    settlements are constructed by a government actor committed
    to protect the public interest; (c) respect for the agency’s
    expertise; and (d) respect for an arms-length agreement
    reached by sophisticated parties. The court distilled these
    factors from decisions discussing judicial approval of consent
    decrees in a variety of circumstances. See 
    id. (citing cases).
    The court further explained that the “second layer of
    swaddling” is the deferential nature of appellate review for a
    district court’s decision approving a consent decree. 
    Id. We adopted
    this framework in United States v. Montrose
    Chemical Corp., 
    50 F.3d 741
    , 743, 746 (9th Cir. 1995).
    C
    Few courts have been called upon to consider what level
    of deference district courts should accord to state-sponsored
    consent decrees. Nonetheless, two of our sister circuits have
    addressed this issue and provided persuasive guidance. In
    City of Bangor v. Citizens Communications Co., 
    532 F.3d 70
    (1st Cir. 2008), the First Circuit decided to accord “some
    deference” to the state agency. It explained:
    The question becomes what deference, if
    any, should be given to a state agency which
    is not charged with implementing CERCLA.
    We recognize the [Maine Department of
    Environmental Protection (“DEP”)] does have
    a mandate under state law to “prevent, abate
    ARIZONA V. RAYTHEON CO.                   35
    and control the pollution of the air, water and
    land and preserve, improve and prevent
    diminution of the natural environment of the
    State.”
    Federal courts generally defer to a state
    agency’s interpretation of those statutes it is
    charged with enforcing, but not to its
    interpretation of federal statutes it is not
    charged with enforcing.
    We choose to accord some deference to
    Maine’s decision to sign onto the Consent
    Decree, but not the same amount of deference
    we would accord to the EPA in a consent
    decree involving the United States. We give
    deference in recognition that the state agency
    has some expertise. The lesser deference does
    not displace the baseline standard of review
    for abuse of discretion.
    
    Id. at 94
    (citations omitted). Arguably, the First Circuit
    overstated the case when it suggested that states are “not
    charged with implementing CERCLA,” as they do have
    substantial roles under the statute as discussed above.
    Nonetheless, the First Circuit recognized that state agencies
    are still due “some deference” when courts evaluate a state
    environmental agency’s decision to enter into a consent
    decree.
    In Commissioner v. Esso Standard, Oil S.A., 
    326 F.3d 201
    , 205 (3d Cir. 2003), the district court approved a
    CERCLA consent decree between the Virgin Islands’
    Department of Planning and Natural Resources and several
    36               ARIZONA V. RAYTHEON CO.
    settling PRPs. The Third Circuit affirmed. 
    Id. at 210.
    In
    doing so, the court accorded deference to the territorial
    agency, explaining: “there is deference to the administrative
    agencies’ input during consent decree negotiations and the
    law’s policy of encouraging settlement.            Where the
    appropriate agency has reviewed the record and has made a
    reasonable determination of fault and damages, that
    determination is owed some deference.” 
    Id. at 207.
    Thus,
    although the Third Circuit did not explicitly address how this
    level of deference differed from the level of deference owed
    to the EPA, it plainly recognized that the EPA was not a party
    and still accorded deference to the territorial agency.
    We previously had an opportunity to address this issue,
    but declined to do so. In Arizona ex rel. Woods v. Nucor
    Corp., 
    825 F. Supp. 1452
    , 1459 (D. Ariz. 1992), the non-
    settling PRPs argued that the district court lacked sufficient
    technical data to approve the settlement, including
    information regarding the extent of contamination, cleanup
    cost, and apportionment of liability. The district court
    reviewed the information submitted by Arizona (including an
    affidavit from Vargas) and found that the there was adequate
    support for the settlement. See 
    id. at 1459–65.
    Throughout
    its analysis, the court suggested that it was according ADEQ
    deference, noting that its role was “not to determine the best
    method for measuring fault and apportioning liability, but
    rather to uphold the method proposed by the ADEQ unless it
    is ‘arbitrary, capricious, and devoid of a rational basis.’” 
    Id. at 1459.
    We affirmed on appeal without discussing the level
    of deference owed to a state environmental agency, holding
    that the district court did not abuse its discretion. See Arizona
    v. Components Inc., 
    66 F.3d 213
    , 215 (9th Cir. 1995). The
    most noteworthy aspect of our decision in Components is that
    ARIZONA V. RAYTHEON CO.                             37
    we did not do what the majority does here: fault the district
    court for deferring to ADEQ.
    Thus, although we have not specifically addressed the
    issue, both the First and Third Circuits have accorded at least
    some deference to state or territorial agencies that entered
    into CERCLA consent decrees. City of 
    Bangor, 532 F.3d at 94
    ; Esso 
    Standard, 326 F.3d at 207
    . The Eighth Circuit has
    also suggested that state agencies are entitled to deference
    when enforcing federal environmental laws. See Comfort
    Lake Ass’n, Inc. v. Dresel Contracting, Inc., 
    138 F.3d 351
    ,
    357 (8th Cir. 1998) (according “considerable deference” to
    administrative enforcement agreement between a state agency
    and a polluter for violations of the federal Clean Water Act).
    These decisions conflict with the majority’s suggestion that
    state environmental agencies are entitled to no deference in
    determining whether an agreement is fair, reasonable, and
    consistent with CERCLA’s objectives.6
    Moreover, the factors discussed by the First Circuit in
    Cannons support extending significant deference to state
    environmental agencies. 
    See 899 F.2d at 84
    . Like the EPA,
    state environmental agencies possess expertise and are
    charged with protecting the public interest. Although
    Congress did not give state agencies as large a role in
    CERCLA enforcement as the EPA, Congress still
    contemplated extensive state involvement. Moreover, given
    the scope of the environmental problems we face as a nation,
    6
    Although the majority indicates that it finds City of Bangor
    “persuasive,” in that case, the First Circuit “accord[ed] some deference to
    [the state agency’s] decision to sign onto the Consent 
    Decree.” 532 F.3d at 94
    . The majority proclaims that the district court erred by doing so
    here.
    38              ARIZONA V. RAYTHEON CO.
    as a practical matter, state involvement is absolutely
    necessary. Similarly, CERCLA’s policy of encouraging
    settlements is not diminished merely because a state entity is
    involved rather than the federal government. Furthermore,
    just as EPA-sponsored settlements may result from arms-
    length agreements reached by sophisticated parties, so may
    those involving state environmental agencies. Thus, most of
    the reasons favoring deference to EPA-sponsored settlements
    also favor deference to state-sponsored settlements.
    In any event, the proper level of deference in any given
    case is not strictly dictated by the identity of the
    governmental actor involved. As the First Circuit explained
    in Cannons, even in cases involving the EPA, there is no set
    level of deference. Rather, the level of deference depends
    upon the “the persuasive power of the agency’s proposal and
    rationale, given whatever practical considerations may
    impinge and the full panoply of the attendant circumstances.”
    
    Cannons, 899 F.2d at 84
    (citation omitted). Thus, in all cases
    involving CERCLA consent decrees, there is a spectrum of
    possible deference that a district court may accord to the
    decision to settle, depending on the particular circumstances
    of the case. At its zenith, deference will be highest for well-
    supported consent decrees involving the EPA. As our sister
    circuits have acknowledged, however, it does not follow that
    state agencies are not entitled to deference concerning their
    decision to sign on to a consent decree. Accordingly, while
    the degree of deference may vary depending on the
    circumstances of the particular case, state-sponsored
    settlements are entitled to deference when a court assesses a
    settlement’s fairness, reasonableness, and benefit to the
    public.
    ARIZONA V. RAYTHEON CO.                        39
    D
    As explained above, judicial deference to the EPA in
    CERCLA consent decrees evolved from the standards courts
    use when evaluating consent decrees in general. Instead of
    focusing on the grounds for deference, the majority seems to
    treat this case as if it presented a statutory interpretation issue.
    Statutory interpretation is the focus of cases such as United
    States v. Mead Corp., 
    533 U.S. 218
    (2001), Chevron, U.S.A.,
    Inc. v. Natural Resources Defense Council, Inc., 
    467 U.S. 837
    (1984), and Skidmore v. Swift & Co., 
    323 U.S. 134
    (1944).
    Similarly, our opinion in Orthopaedic Hospital v. Belshe,
    
    103 F.3d 1491
    , 1495–96 (9th Cir. 1997), stands for the
    unremarkable proposition that state agency interpretations of
    federal statutes that the agencies are not charged with
    enforcing are not entitled to Chevron deference. But this case
    does not turn on a question of statutory interpretation.
    Most CERCLA consent decree actions do not present
    questions about whether the agency’s implementation of a
    particular statutory provision (or filling of a statutory gap) is
    entitled to deference. Cf. 
    Mead, 533 U.S. at 229
    . Nor do
    they generally involve an agency regulatory or adjudicatory
    rulemaking—or even less formal agency policy statements,
    manuals, or enforcement guidelines—which may have broad
    implications for third parties and unrelated controversies. Cf.
    
    id. at 233–34.
    Instead, most cases involving CERCLA
    consent decrees focus primarily on whether the agency made
    a reasonable and fair assessment in a particular case. This is
    not a question of statutory interpretation, but rather of the
    exercise of the authority and discretion lodged with the
    agency.      Considerably more so than judges, state
    environmental agencies are perfectly capable of making those
    determinations.
    40                 ARIZONA V. RAYTHEON CO.
    One of the factors that we use when evaluating consent
    decrees is whether they are “consistent with the purposes that
    CERCLA is intended to serve.” 
    Montrose, 50 F.3d at 743
    (citation omitted). In some cases—but not here—applying
    this factor may present questions of statutory interpretation.
    In those cases, all other things being equal, a state sponsored-
    consent decree would be entitled to less deference than an
    EPA-sponsored consent decree. But most often, determining
    consistency with CERCLA will only require a rote
    assessment of whether the decree complies with CERCLA’s
    well-pronounced goals and is in the public interest.7 Cf.
    United States v. Charles George Trucking, Inc., 
    34 F.3d 1081
    ,
    1086 (1st Cir. 1994) (indicating that the “overarching goals
    of CERCLA” include “accountability, the desirability of an
    unsullied environment, and promptness of response
    activities” (quoting 
    Cannons, 899 F.2d at 91
    )). State agencies
    are equally capable of undertaking this assessment as is the
    EPA. Thus, a state agency like ADEQ is entitled to some
    deference concerning its determination that a particular
    agreement is “fair, reasonable, and consistent with
    CERCLA’s objectives.”
    III
    Applying the proper level of deference owed to a state
    environmental agency, I would hold that the district court did
    not abuse its discretion in approving the consent decrees here.
    The majority’s reliance on Montrose to reach the opposite
    conclusion is misplaced. In 
    Montrose, 50 F.3d at 743
    , we
    vacated the district court’s approval of the consent decree and
    7
    Indeed, we, along with our sister circuits, have occasionally formulated
    this factor as whether the settlement is consistent with “the public
    interest.”

    remanded. We explained that the district court had to
    compare the proportion of projected costs to be paid by the
    settling defendants with the proportion of liability attributable
    to them, taking into account “reasonable discounts for
    litigation risks, time savings, and the like that may be
    justified.” 
    Id. at 747
    (citing Charles George 
    Trucking, 34 F.3d at 1087
    ). The district court had “no evidence at all”
    upon which to base any assessment of the government’s
    estimates of responsibility and damage, and thus it could not
    evaluate the reasonableness and fairness of the decree. 
    Id. at 746–48.
    In particular, the district court had largely relied on
    a special master’s assessment of the settlement without
    independently evaluating the damage estimate. 
    Id. at 746.
    Thus, we found that the district court had neglected its
    “obligation to independently ‘scrutinize’ the terms of [the]
    settlement.”8 
    Id. at 747.
    We accordingly remanded for the
    district court to:
    determine the proportional relationship
    between the [amount] to be paid by the
    settling defendants and the governments’
    current estimate of total potential damages.
    The court should evaluate the fairness of that
    proportional relationship in light of the degree
    of liability attributable to settling defendants.
    
    Id. at 747
    (citing Charles George 
    Trucking, 34 F.3d at 1087

    The majority repeatedly suggests that the district court here failed to
    independently scrutinize the agreements, citing this language. Unlike
    Montrose, where the district court had relied on the special master almost
    completely, the district court evaluated the agreements itself in this case.
    42              ARIZONA V. RAYTHEON CO.
    2011), Montrose remains the only example of a circuit court
    reversing a district court’s approval of a CERCLA consent
    decree for lack of a factual basis before the majority’s
    decision in this case.
    Here, the record before the district court shows that under
    ADEQ’s formula, each settling defendant paid damages
    directly corresponding to ADEQ’s estimated degree of
    liability. It does not appear that ADEQ provided the settling
    defendants with any discount for litigation risks or time
    savings, even though such discounts are permissible under
    
    Montrose, 50 F.3d at 747
    . A settlement corresponding
    precisely to the settling defendant’s estimated share of
    liability is necessarily reasonable. See Charles George
    
    Trucking, 34 F.3d at 1087
    (noting that a settlement was
    favorable to the government agencies where the payment
    corresponded to the group’s share of responsibility multiplied
    by the highest estimate of clean-up costs). Moreover,
    although ADEQ did not specifically set forth the settlement
    amount and share for each settling defendant, it did provide
    the district court with a basis for evaluating its estimates by
    explaining its methodology in detail and setting out the total
    value of the settlements and anticipated costs. Requiring
    ADEQ to list the settlement amounts and share of liability for
    each settling defendant would be pointless when there is no
    dispute that the estimate and settlement share are the same.
    Cf. 
    Cannons, 899 F.2d at 87
    (“The logic behind these
    concepts dictates that settlement terms must be based upon,
    and roughly correlated with, some acceptable measure of
    comparative fault, apportioning liability among the settling
    parties according to rational (if necessarily imprecise)
    estimates of how much harm each PRP has done.”).
    ARIZONA V. RAYTHEON CO.                             43
    The Intervenors’ arguments here resemble arguments that
    the First Circuit rejected in Charles George Trucking. In that
    case, the First Circuit affirmed a settlement even though the
    appellants contended that the district court had failed to
    explain the allocation of responsibility either within or among
    the classes of 
    defendants. 34 F.3d at 1086
    –88. The First
    Circuit observed that it is not always possible to explain an
    allocation of liability in minute detail given an incomplete
    historical record. 
    Id. at 1088.
    Although we did not
    specifically discuss these arguments, we repeatedly cited
    Charles George Trucking with approval in 
    Montrose, 50 F.3d at 746
    –47.
    The question here is whether the PRPs are entitled to
    know specifically how ADEQ developed its estimate for the
    shares of liability attributable to each settling defendant. As
    the First Circuit explained in Cannons, however, this is an
    area where the courts will typically defer to the EPA in light
    of its 
    expertise. 899 F.2d at 87
    (“[W]hat constitutes the best
    measure of comparative fault at a particular Superfund site
    under particular factual circumstances should be left largely
    to the EPA’s expertise.”). Indeed, at an early stage in the
    process, some of the state’s allocations are necessarily based
    on qualitative information and expert experience rather than
    strict quantitative analysis. Accordingly, the district court
    properly deferred to ADEQ’s choice of measuring
    comparative fault, which was adequately explained and
    supported.9
    9
    Even the majority concedes that ADEQ may have similar expertise to
    the EPA. Indeed, among other things, ADEQ is statutorily charged with:
    protecting the environment; protecting the quality of the air and water;
    abating air and water pollution; restoring and reclaiming polluted areas;
    regulating the storage, handling, and transportation of pollutants; ensuring
    44                  ARIZONA V. RAYTHEON CO.
    Instead of following our precedents, the majority takes the
    district court to task for failing to “substantively engage with
    the parties’ proposed agreements.” The majority requires the
    district court on remand to wade deep into the abyss of
    liability allocation and decide not only whether the settlement
    amounts are fair and reasonable, but also gauge the accuracy
    of ADEQ’s allocation against a 100,000 page record and
    technical guidelines. As a practical matter, requiring a
    district court to delve into the details of how an agency
    allocated responsibility within a category of PRPs based on
    factual information concerning a variety of measures (e.g.,
    volume, toxicity, etc.) will consume considerable resources
    and require expertise that most judges do not possess. See
    Gen. Elec. Co. v. Joiner, 
    522 U.S. 136
    , 148 (1997) (Breyer,
    J., concurring) (noting that “judges are not scientists and do
    not have the scientific training that can facilitate the making
    of such decisions”). A district court should not have to
    that state environmental laws and regulations are consistent with
    corresponding federal laws; and approving remediation levels. Ariz. Rev.
    Stat. § 49-104. More specifically, as it relates to ADEQ’s work on this
    case, Vargas averred that she has 23 years of experience at ADEQ and
    was the same engineer who performed the analysis at issue in Nucor.
    Notably, when we affirmed in the district court’s decision in Nucor, we
    took no issue with the district court’s deference to ADEQ. See
    
    Components, 66 F.3d at 215
    .
    For recognizing the factual and legal backdrop underlying the district
    court’s decision, the majority accuses me of undertaking a de novo review
    and usurping the district court’s role. Not so. Although I have the benefit
    of a post hoc perspective that necessarily comes with appellate review (not
    to mention knowledge of the majority’s newly-fashioned legal standards),
    I have simply evaluated the district court’s reasoning in light of the record
    as a whole, which we are required to do when reviewing a decision for
    abuse of discretion. See, e.g., McKinley v. City of Eloy, 
    705 F.2d 1110
    ,
    1117 (9th Cir. 1983).
    ARIZONA V. RAYTHEON CO.                              45
    undertake the equivalent of an expert deposition every time
    it is asked to approve a state-sponsored CERCLA consent
    decree.10
    Here, the Intervenors have not suggested that the
    information in the record points to some other estimate of the
    settling defendants’ liability; they simply claim that the
    record was inadequate. This is insufficient to carry the
    “heavy burden” that the Intervenors bear to show that district
    court’s approval of the consent decree was an abuse of
    discretion. See Esso 
    Standard, 326 F.3d at 207
    . It is obvious
    that the Intervenors are contesting the consent decrees
    because they do not like the deals they were offered by
    ADEQ. As is their right, they refused ADEQ’s settlement
    offers. But they have no right to a settlement offer of their
    choice. Indeed, the purpose of judicial review is to ensure
    that proposed settlements further the public interest by
    holding polluters responsible for the damage that they
    caused.11 It is not to guarantee PRPs a good deal.
    The Intervenors’ intent appears to be to hold up fair and
    reasonable consent decrees with settling PRPs in order to
    10
    To the extent that the majority’s opinion merely requires the district
    court to further explain its findings that are obvious from the record, it is
    promoting form over substance.
    11
    See United States v. Rohm & Haas Co., 
    721 F. Supp. 666
    , 680 (D.N.J.
    1989) (“The court’s core concern in deciding whether to approve this
    proposed decree is with ensuring that the decree furthers the public
    interest as expressed in CERCLA.”); H.R. Rep. No. 99-253, pt. III, at 19
    (1985) (indicating that the primary reason for judicial review was to
    “protect against improper or ‘bad faith’ settlements.”); H.R. Rep. No. 99-
    253, pt. I, at 59 (1985), reprinted in 1986 U.S.C.C.A.N. 2835, 2841
    (stating that judicial review was intended to guard against “[s]weetheart
    deals” and ensure that agreements were “in the public interest.”).
    46                   ARIZONA V. RAYTHEON CO.
    create more leverage in their negotiations with ADEQ.12
    Such delay is not in the public interest. Cf. United States v.
    Asarco, Inc., 
    430 F.3d 972
    , 983 (9th Cir. 2005) (noting that
    the purpose of a consent decree is “to enable parties to avoid
    the expense and risk of litigation while still obtaining the
    greater enforceability (compared to an ordinary settlement
    agreement) that a court judgment provides”). The majority’s
    approach gives polluters more power in their negotiations
    with the states and is more likely to push the states to bypass
    judicial approval and opt for administrative settlements (as
    they are entitled to do under 42 U.S.C. § 9613(f)(2)), denying
    the judiciary the opportunity to protect the public interest by
    ensuring that the states are not cutting sweetheart deals with
    those polluters.
    IV
    The majority’s conclusion appears to be founded upon the
    flawed premise that state environmental agencies entering
    consent settlements under CERCLA are entitled to no
    deference concerning their conclusion that a settlement is fair
    and reasonable. In doing so, the majority fails to appreciate
    the origins of CERCLA deference. Moreover, the majority
    12
    The Intervenors claim that they fear being held jointly and severally
    liable for the settling parties’ shares of liability should those shares exceed
    the settlement amounts. However, the consent decrees provide that if the
    settling parties’ shares are eventually deemed to be greater than the
    settlement amount, “the difference shall be deemed an orphan share of
    liability pursuant to” Arizona Revised Statutes § 49-281(10). Under state
    law, Arizona is responsible for funding orphan shares. See Ariz. Rev.
    Stat. § 49-282(E)(2)(e). At oral argument, the Intervenors expressed a fear
    that the law could change. However, the consent decrees provide that the
    terms “have the meanings assigned to them under WQARF and CERCLA
    as of the date this Consent Decree becomes final.”
    ARIZONA V. RAYTHEON CO.                     47
    vastly and unwisely expands the required level of judicial
    scrutiny for CERCLA consent decrees. The majority’s
    decision will significantly restrict state agencies’ ability to
    enter into early CERCLA consent decrees to the detriment of
    the environment, the statutory framework envisioned by
    Congress, and PRPs seeking to resolve their liability early in
    the process. I respectfully dissent.
