    CUDAHY, Circuit Judge. Keystone Consolidated Indus-
    tries, Inc., and Valhi, Inc.1 (collectively, Keystone) operate
    a number of mills that manufacture wire products, chemi-
    cals and other industrial materials, and have done so in
    some capacity since the early 1900s. Beginning in 1942 and
    1
    In 1984, Keystone spun off some of its businesses, facilities
    and assets, including coverage rights associated with the trans-
    ferred facilities, to a predecessor of Valhi.
    2                                               No. 05-3412
    continuing through the late 1980s, Keystone purchased
    dozens of comprehensive general liability and excess
    umbrella insurance policies from Employers Insurance
    Company of Wausau (Wausau). Keystone
    seeks indemnification from Wausau for approximately $13.5
    million, which represents the costs it has incurred
    or expects to incur cleaning up environmental damage
    that its operations caused at four sites in Illinois and
    Indiana. Wausau has refused to indemnify Keystone on
    the theory that the policies require indemnification only
    when a lawsuit triggers its duty to defend. The district
    court agreed with Wausau and granted its motion for
    summary judgment. Because, under Illinois law, the duty
    to indemnify may arise even in absence of a lawsuit trigger-
    ing the duty to defend, we reverse the judgment of the
    district court and remand for further proceedings.
    I. Background
    Four of Keystone’s industrial sites are at issue in this
    case: Peoria, Impex, Chicago Steel & Wire and Ninth
    Avenue. Keystone has requested indemnification from
    Wausau for costs associated with cleaning up ground-
    water and other contamination at each site. The Peoria Site
    constitutes the most extensive claim by far; the
    others involve only a fraction of the Peoria Site’s cleanup
    costs. We summarize the relevant facts about each site
    and its attendant claims and costs below.
    Keystone opened a wire mill near Peoria, Illinois in 1901.
    This wire mill, which is one of the largest in North America,
    draws and finishes wire products such as fence materials
    and nails. In 1917, Keystone opened a steel mill, which
    produces steel rod coils, at the same facility in Peoria.
    Keystone began to use chlorinated solvents, including
    trichloroethylene (TCE), in vapor degreasing cabinets to
    clean nails in the wire mill at the Peoria Site in 1958. By
    No. 05-3412                                                  3
    the 1960s, Keystone was using four such vapor degreasing
    cabinets. Around 1976, Keystone switched from TCE
    to another chlorinated solvent known as 1, 1, 1—
    trichloroethane (TCA). Keystone abandoned the chlorinated
    solvents and converted to water-based cleaning agents in
    1993.
    During the time that Keystone used the chlorinated
    solvents in its degreasing cabinets, it—as part of the
    cleaning process—discharged wastewater containing
    spent pickle liquor, which is sulfuric acid used to clean steel
    rods for wire drawing. Because spent pickle liquor contains
    lead and chromium, the U.S. Environmental Protection
    Agency (U.S. EPA) has designated it a hazardous waste
    (known as K062). 
    40 C.F.R. § 261.32
     and Part 261 App. VII
    (2006).
    On July 18, 1986, the United States filed a complaint
    against Keystone alleging that its Peoria Site violated the
    Resource Conservation and Recovery Act, 
    42 U.S.C. § 6901
    -
    7000 (2006) (RCRA) and seeking to enjoin it from depositing
    spent pickle liquor into earthen impoundments at the site.
    On June 29, 1988, Keystone entered into a consent decree
    with the United States. In that consent decree, Keystone
    agreed to pay a civil penalty and to close its spent pickle
    liquor impoundments pursuant to a plan it would negotiate
    with the Illinois Environmental Protection Agency (IEPA).
    During a 1988 sampling required for the closing of the
    spent pickle liquor impoundments, Keystone discovered
    TCE and TCA contamination (collectively, the TCE contam-
    ination) in the groundwater beneath the Peoria Site.
    On October 31, 1989, Keystone began the installation and
    sampling of twenty-six groundwater monitoring wells to
    determine the extent of the TCE contamination. Keystone
    notified Wausau of its potential liability for TCE contami-
    nation on November 2, 1989. In 1993, the IEPA filed a
    complaint and proposed consent decree in Illinois state
    4                                                No. 05-3412
    court essentially alleging that Keystone failed to meet its
    obligations under the 1988 consent decree. In 2000, Key-
    stone submitted claims against the Wausau policies seeking
    indemnification for costs incurred in remediating the TCE
    contamination. Wausau has thus far refused to pay.
    Keystone expects to incur a total cost of approximately $11
    million in cleaning up the Peoria Site. It has, to date,
    incurred costs of about $4.5 million.
    The Impex Site is a former metal-working plant located
    in Crawfordsville, Indiana. The National Lock Company, a
    subsidiary of Keystone, acquired the facility in 1964. While
    Keystone owned the plant, it used volatile organic com-
    pounds (VOCs) for metal cleaning and finishing. Keystone
    arranged for an environmental assessment of the property
    in preparation for its proposed sale. This assessment
    identified VOC contamination of the soil and groundwater
    exceeding permissible state and federal levels. Keystone
    submitted a voluntary cleanup plan to the Indiana Depart-
    ment of Environmental Management in 1991. Under that
    plan, Keystone installed and began to operate both a VOC
    soil vapor system and a groundwater pump-and-treat
    system at the Impex Site in 1992.
    Keystone’s investigation and cleanup costs at the Impex
    Site exceed $2.1 million. Keystone seeks indemnifica-
    tion from Wausau for expenses incurred and a declaration
    that Wausau will be liable for future costs.
    Keystone acquired the third site, the Chicago Steel &
    Wire Site, in 1964. During a site investigation in 2000,
    Keystone discovered VOC and lead contamination in the
    soil and groundwater. Keystone notified the IEPA of its
    findings and enrolled the site in Illinois’ pre-notice environ-
    mental remediation program. The IEPA approved Key-
    stone’s remediation in August 2002. Keystone incurred a
    total of about $500,000 relating to this remediation
    and seeks indemnification for those and future costs.
    No. 05-3412                                                  5
    The final site relating to this lawsuit is the Ninth Avenue
    Site, a former waste disposal site located in Gary, Indiana.
    Keystone transferred spent pickle liquor from the Chicago
    Steel & Wire Site to the Ninth Avenue Site for disposal
    between April 30, 1973, and November 6, 1975. In 1989, the
    U.S. EPA ordered Chicago Steel & Wire and other poten-
    tially responsible parties to investigate and remediate the
    site. Keystone has incurred costs of approximately $1.1
    million to date to remediate the Ninth Avenue Site.
    The district court granted Wausau’s motion for sum-
    mary judgment, concluding: (1) that Illinois courts require
    the filing of a formal complaint in a court of law to trigger
    the “duty to defend” clause of a comprehensive general
    liability insurance contract; and (2) that where there is no
    duty to defend, there will be no duty to indemnify. Keystone
    timely appealed and now seeks a reversal of summary
    judgment so that it may proceed to trial. Keystone also
    argues that, even if Illinois law requires a lawsuit to trigger
    an insurer’s duty to indemnify, the IEPA’s 1993 complaint
    alleging that Keystone failed to prevent and remediate the
    TCE contamination satisfies that standard for the Peoria
    Site.
    II. Discussion
    We review a district court’s grant of summary judg-
    ment de novo. Magin v. Monsanto Co., 
    420 F.3d 679
    , 686
    (7th Cir. 2005). Federal jurisdiction in this case rests upon
    diversity of citizenship. 
    28 U.S.C. § 1332
    (a)(1). The parties
    agree that Illinois law governs the substantive issues
    underlying the appeal.
    A. The Duty to Defend and the Duty to Indemnify Under
    Illinois Law
    The district court concluded that, under Illinois law,
    where an insurance policy includes both the duty to de-
    6                                                     No. 05-3412
    fend and the duty to indemnify, the duty to indemnify
    arises only in circumstances involving lawsuits. Proceed-
    ing from that conclusion, the district court then reasoned
    that since the insurance policies at issue contain both
    duties, Keystone’s indemnity rights must be limited to
    claims involving lawsuits. Both steps of the district
    court’s reasoning, however, are erroneous. First, although
    some authority suggests otherwise,2 it appears fairly
    well settled that under Illinois law, an insurance policy may
    2
    There appears to be some confusion in the Illinois courts on this
    point, which seems to stem primarily from Crum & Forster
    Managers Corp. v. Resolution Trust Corp., 
    620 N.E.2d 1073
     (Ill.
    1993). In Crum & Forster Managers Corp., the Illinois Supreme
    Court said that “[c]learly, where there is no duty to defend, there
    will be no duty to indemnify.” 
    Id. at 1081
    . Taken literally and
    ignoring context, this statement would seem to preclude indemni-
    fication in the absence of a lawsuit under any circumstances.
    When the statement is read in context, however, it becomes
    evident that Illinois law is significantly more nuanced. See
    generally Cent. Ill. Light Co. v. Home Ins. Co., 
    821 N.E.2d 206
     (Ill.
    2004); Sokol & Co. v. Atl. Mut. Ins. Co., 
    430 F.3d 417
     (7th Cir.
    2005). The statement, as originally appearing in Crum & Forster
    Managers Corp., was intended to summarize a more complex,
    case-specific, proposition: the insurer was not obligated to defend
    or indemnify the insured because those obligations arise only
    under circumstances stated in the policy. 
    620 N.E.2d at 1081
    ; see
    also Sokol & Co., 
    430 F.3d at 420-21
    . Under the facts of Crum &
    Forster Managers Corp., the activities for which the insured
    sought indemnification could never have fallen within the stated
    coverage of the policy. 
    620 N.E.2d at 1081
    . In fact, the only case
    we find that takes the proposition literally and at face value
    seems to be an anomaly. Zurich Ins. Co. v. Carus Corp., 
    689 N.E.2d 130
    , 133 (Ill. Ct. App. 1997) (concluding, without analysis,
    that the duty to indemnify hinged on the duty to defend); Sokol &
    Co., 
    430 F.3d at
    421 n.1. Given this context, it becomes apparent
    that Crum & Forster Managers Corp. does not establish a bright-
    line rule to preclude indemnification in the absence of a lawsuit.
    No. 05-3412                                                  7
    entitle the insured to indemnification for claims that do not
    arise from the resolution of a lawsuit, so long as those
    claims satisfy any requirements set forth in the relevant
    provisions of the policy. See Cent. Ill. Light Co. v. Home Ins.
    Co., 
    821 N.E.2d 206
    , 215-18 (Ill. 2004) (CILCO); see also
    Sokol & Co. v. Atl. Mut. Ins. Co., 
    430 F.3d 417
    , 420-21 (7th
    Cir. 2005). Second, the language of Keystone’s policies
    arguably supports a conclusion that Wausau has a duty to
    indemnify Keystone that is independent of its duty to
    defend.
    An insurer’s most fundamental duty under its insur-
    ance contracts is its duty to indemnify—that is, its duty
    either to reimburse the insured for losses it incurs directly
    or to pay sums that the insured becomes legally obligated
    to pay to others. ALAN D. WINDT, INSURANCE CLAIMS
    AND DISPUTES: REPRESENTATION OF INSURANCE COMPANIES
    AND INSUREDS § 6:1 (4th ed. Supp. 2006). An insurer’s duty
    to indemnify often involves its duty to defend the insured in
    the event of a lawsuit or its functional equivalent. Id. § 4:1;
    Lapham-Hickey Steel Corp. v. Nat’l Surety Corp., 
    633 N.E.2d 199
    , 201 (Ill. Ct. App. 1994). But although the duties
    to defend and to indemnify may be related, they are not
    necessarily mutually dependent or coextensive. See, e.g.,
    Sokol & Co., 
    430 F.3d at 421
     (“[W]hile the duty
    to indemnify may sometimes nest inside the duty to defend,
    that will not always be the case.”).
    Moreover, the fact that the duty to defend is generally
    broader than the duty to indemnify does not mean, as the
    district court believed, that where there is no duty to defend
    there can be no duty to indemnify. The duty to defend is
    generally broader because it arises in cases of arguable or
    potential coverage. That is, an insured need only put the
    insurer on notice of the claim in order to trigger the in-
    surer’s duty to defend. WINDT § 4:1. The duty to indemnify,
    however, arises only in circumstances of actual coverage; if
    the insurance policy does not cover what is alleged in the
    8                                               No. 05-3412
    claim, the insurer will not have a duty to indemnify based
    on that claim. Crum & Forster Managers Corp. v. Resolu-
    tion Trust Co., 
    620 N.E.2d 1073
    , 1081 (Ill. 1993); see also
    Sokol & Co., 
    430 F.3d at 421
    .
    But these characteristics do not lead to the conclusion
    that the factors required to trigger the generally broader
    duty to defend are always required to trigger the duty
    to indemnify. In many circumstances, the duty to indemnify
    explicitly involves the duty to defend a lawsuit or its
    functional equivalent. In other cases, however, the duty
    to indemnify is separate from and independent of the duty
    to defend. In short, while a lawsuit may be sufficient to
    trigger an insurer’s duty to indemnify, it is not a necessary
    condition under Illinois law.
    Given these conclusions, the next logical question is what
    is required to trigger an employer’s duty to indemnify. The
    answer to that question is found in the language of the
    policies. Under Illinois law, construction of insurance
    policies is a question of law. Outboard Marine Corp. v.
    Liberty Mut. Ins. Co., 
    607 N.E.2d 1204
    , 1212 (Ill. 1992).
    Policies will be construed as a whole; if the words used
    in the policies are clear, then they must be given their
    “plain, ordinary, and popular meaning.” CILCO, 
    821 N.E.2d at
    213 (citing Outboard Marine Corp, 
    607 N.E.2d at 1212
    ).
    With those principles in mind, we turn next to the Wausau
    policies.
    B. The Wausau Policies
    Keystone purchased both general liability and excess
    umbrella policies from Wausau beginning in 1942 and
    continuing through 1987. The general liability policies cover
    Keystone from 1942 into the 1980s; the excess umbrella
    policies cover Keystone from 1969 through 1979. Although
    each of the general liability and excess umbrella policies is
    somewhat unique, Wausau used two basic insuring agree-
    No. 05-3412                                                       9
    ments for the general policies and two basic insuring
    agreements for the excess umbrella policies.
    Each of Keystone’s general liability policies contains a
    duty-to-defend provision requiring Wausau to defend any
    “suit” against the insured “seeking damages” on account of
    property damage. Keystone concedes that under these
    general liability policies, Wausau’s obligation to defend is
    triggered only by the filing of a “suit.” The term “suit,”
    under Illinois law, “requires the commencement of some
    action in a court of law before an insurer’s duty to defend is
    triggered.” Lapham-Hickey Steel Corp. v. Prot. Mut. Ins.
    Co., 
    655 N.E.2d 842
    , 847 (Ill. 1995).
    But, as earlier explained, the fact that Wausau’s duty
    to defend does not arise unless a lawsuit is filed does not
    mean that Wausau’s duty to indemnify depends on the
    filing of that lawsuit. In fact, the policies here support a
    conclusion that the duty to indemnify is separate and
    independent. The pre-1968 general liability policies grant
    Keystone coverage for property damage so long as the
    liability is “imposed by law” and is “caused by accident.”3
    The 1969-1985 general liability policy language changed
    slightly, in that liability under these policies are based
    on an “occurrence” rather than on an “accident.” Under
    the general liability policies, Wausau pledged to “pay on
    behalf of the insured all sums which the insured shall
    3
    Both Keystone and Wausau reproduce the relevant policy
    language in their briefs. The specific language of the pre-1968
    policies states that:
    To pay on behalf to the insured all sums which the insured
    shall become obligated to pay by reason of liability imposed
    upon him by law or assumed by him under any written
    contract for damages, because of injury to or destruction of
    property, including the loss of use thereof, caused by accident.
    (Appellant’s Br. 5; Appellee’s Br. 13.)
    10                                                     No. 05-3412
    become legally obligated to pay as damages because of”
    bodily injury or property damage “caused by an occurrence.”
    The policy further states that Wausau “shall have the right
    and duty to defend any suit against the insured seeking
    damages” on account of bodily injury or property damage
    “and may make such investigation and settlement of any
    claim or suit” but Wausau “shall not be obligated to pay any
    claim or judgment or to defend any suit after the applicable
    limit of the company’s liability has been exhausted by
    payment of judgments or settlements” (emphasis added).
    To unpack that language a bit, although the general
    liability policies base Wausau’s obligation to defend not
    illogically on the filing of a “suit,” the indemnity terms
    require Wausau to “pay on behalf of the insured all sums
    which the insured shall become legally obligated to pay
    as damages.”4 In addition, the indemnity terms also state
    that Wausau “shall not be obligated to pay any claim or
    judgment” once the policy limits are exhausted. The
    disjunctive reference to claims or judgments is significant;
    4
    The full text of the 1969-1985 policies reads:
    The company will pay on behalf of the insured all sums which
    the insured shall become legally obligated to pay as damages
    because of
    Coverage A, bodily injury or
    Coverage B, property damage
    to which this insurance applies, caused by an occurrence, and
    the company shall have the right and duty to defend any suit
    against the insured seeking damages on account of
    such bodily injury or property damages, even if any of the
    allegations of the suit are groundless, false or fraudulent, and
    may make such investigation and settlement of any claim or
    suit as it deems expedient, but the company shall not be
    obligated to pay any claim or judgment or to defend any suit
    after the applicable limit of the company’s liability has been
    exhausted by payment of judgments or settlements.
    (Appellant’s Br. 6-7; Appellee’s Br. 14.)
    No. 05-3412                                                     11
    it lends some support to reasoning that a lawsuit is not
    necessary to trigger the duty to indemnify. If it were, the
    policies likely would not make a disjunctive reference to
    “claims.”
    Keystone’s excess umbrella policies likewise indicate that
    Wausau’s duty to indemnify is separate from and independ-
    ent of the duty to defend. The 1969-71 excess umbrella
    policies require Wausau to pay on Keystone’s behalf “all
    sums” which Keystone becomes obligated to pay “by reason
    of liability imposed . . . by law.” The policies define “sums”
    as the insured “loss.” The policies also expressly provide
    that defense costs for either “claims” or “suits” are covered,
    with “expenses” to be included within the definition of
    “loss.”5
    5
    The 1969-1971 excess umbrella policies provide that:
    Wausau agrees:
    COVERAGE. To pay on behalf of the insured all sums
    which the insured shall become obligated to pay, either
    by adjudication or compromise, by reason of the liability
    imposed upon the insured by law or assumed by the
    insured under any contract for damages because of
    personal injury and property damage, and all expenses
    incurred by the insured or the company, hereinafter
    called “loss.”
    The term “expenses” as used herein shall mean expenses
    incurred by the insured or the company in connection
    with the investigation, negotiation, adjustment, settle-
    ment and defense of any claims or suits alleging personal
    injury or property damage and seeking damages which
    are payable under the terms of this policy.
    ...
    It is agreed that with respect to any occurrence not

    The 1972-79 excess umbrella policies require Wausau to
    pay “all sums in excess of the retained limit which the
    insured shall become legally obligated to pay . . . as dam-
    ages because of . . . property damage.” Additionally, the
    policies require Wausau to pay Keystone’s defense costs
    once the primary coverage is exhausted for claims or suits.6

    (...continued)
    the terms and conditions of this policy except for the
    amount of the retained limit, the company shall:
    (A) Defend any suit against the insured alleging
    such injury, sickness, disease or destruction and
    seeking damages on account thereof . . . .
    (Appellant’s Br. 9; Appellee’s Br. 15-16.)
    6
    The 1972-1979 excess umbrella policies provide that:
    Wausau agrees:
    I. COVERAGE. To pay on behalf of the insured all sums
    in excess of the retained limit which the insured shall
    become legally obligated to pay, or with the consent of
    the company agrees to pay, as damages because of
    Coverage A—Personal Injury,
    Coverage B—Property Damage, or
    Coverage C—Advertising Injury
    To which this policy applies arising out of an occurrence.
    II. INVESTIGATION, DEFENSE, SETTLEMENT,
    ASSISTANCE AND COOPERATION. With respect to
    any claim or suit seeking damages payable under this
    policy and for which no defense is provided by underlying
    insurance of by any other valid and collectible insurance
    available to the insured,
    (A) The Company may elect, but shall not be re-
    quired, to assume the investigation, defense or

    Both the 1969-71 and the 1972-79 excess umbrella policies
    refer to claims or suits. Once again, the disjunctive “or” is
    significant. Its inclusion suggests that claims are to be
    distinguished from “suits.” This language suggests that,
    under the excess umbrella policies, Wausau’s duty to
    defend, like its duty to indemnify, may be triggered by
    something less than a lawsuit.
    The excess umbrella policies here are fundamentally
    different from policies imposing a duty to defend only in the
    event of lawsuits. If Wausau is correct that its duty to
    defend requires a formal suit, then the reference to “claims”
    would be mere surplusage, which is problematic. It is well
    settled that reviewing courts will give meaning to each term
    in an insurance policy. See CILCO, 
    821 N.E.2d at 214
    .
    There is a colorable argument, then, that the excess
    umbrella policies impose upon Wausau a duty to defend not
    only in the event of lawsuits but also in the event of claims
    not taking the form of suits. If, under the excess umbrella
    policies, a lawsuit is not necessary to trigger Wausau’s duty

    to defend, then—even under a narrow reading of the duty
    to indemnify—a lawsuit certainly would not be required to
    trigger the duty to indemnify.
    But although the potential construction of Wausau’s
    duty to defend under the excess umbrella policies pro-
    vides interpretative support for the conclusion that a
    lawsuit is also not required to trigger its duty to indemnify,
    the duty to defend is not directly before us. The claims in
    this case center on Wausau’s duty to indemnify. Because a
    duty to indemnify separate from and independent of a duty
    to defend is cognizable under Illinois law and because both
    Keystone’s general liability and excess umbrella policies
    suggest that Wausau’s duty to indemnify is in fact based on
    different conditions from its duty to defend, the district
    court erred in granting summary judgment to Wausau on
    the grounds that a lawsuit was necessary to trigger the
    duty to indemnify.
    Yet that does not end our inquiry. Although the duty
    to indemnify and the duty to defend are separate and
    independent in Keystone’s policies, those policies require
    that Keystone be legally obligated to pay damages before
    Wausau’s duty to indemnify attaches. Understanding
    CILCO is therefore critical to understanding the indemnifi-
    cation terms of the Keystone policies. The CILCO policies,
    like those at issue here, also hinged indemnification on the
    insured’s “legal obligation” to pay damages. But CILCO
    specifically held that a statutory obligation standing alone
    was insufficient to trigger the duty to indemnify. 
    Id.
     at 224-
    25. In so holding, the Illinois Supreme Court concluded that
    “[a]t a minimum, the insured must be acting in response to
    a claim.” 
    Id. at 225
    . That claim, however, “need not neces-
    sarily be in the form of a demand letter, particularly when
    the legal obligation being asserted is based on a strict
    liability statute.” 
    Id.
     Thus, although a lawsuit is not always
    required to trigger an insurer’s duty to indemnify, here (as
    in CILCO) the policies require that some claim or articu-
    No. 05-3412                                                  15
    lated demand assert a legal obligation on the part of
    Keystone to remediate the environmental contamination.
    The key question with regard to each of the four sites,
    then, is whether Keystone undertook its cleanup measures
    gratuitously or in response to a demand or coercive or
    intimidating suggestion by an enforcement agency. See 
    id. at 225
     (concluding that CILCO was operating under a legal
    obligation when it agreed to participate in a voluntary
    cleanup program because the IEPA suggested that it
    could do the necessary cleanup “the easy way or the hard
    way”). No lawsuit was filed in connection with the Impex
    Site, the Chicago Steel & Wire Site or the Ninth Avenue
    Site. Keystone admits that it discovered contamination at
    the Impex Site and the Chicago Steel & Wire Site on its
    own initiative. Keystone also admits that it enrolled these
    sites in voluntary remediation programs. But the district
    court did not consider whether coercive suggestions
    caused Keystone to undertake this remedial action. Al-
    though CILCO precludes the argument that mere statutory
    liability is sufficient to trigger an insured’s legal obligation
    to remediate, this requirement does not eliminate the
    circumstance of demands or coercive suggestions made by
    enforcement agencies.
    Likewise, although there was no formal lawsuit against
    Keystone relating to the Ninth Avenue Site, the record
    indicates that Keystone undertook remedial action there
    only after the U.S. EPA ordered it to investigate and
    remediate. Since CILCO contemplates the possibility that
    such pressure may be sufficient to constitute a “claim” and
    to impose a sufficiently focused legal obligation on Key-
    stone, the lack of a formal lawsuit does not seem to preclude
    indemnification under the policies. 
    Id. at 225-26
    .
    Finally, Keystone contends that it undertook remedial
    action at the Peoria Site only in response to pressure from
    the IEPA, including the 1993 complaint alleging that
    16                                               No. 05-3412
    Keystone failed to meet its obligations under the 1988
    consent decree. The district court concluded that the 1993
    complaint did not trigger Wausau’s duty to defend (and
    therefore its duty to indemnify) because the complaint
    alleged only procedural violations on the part of Keystone.
    But this analysis does not consider whether Keystone acted
    voluntarily or in response to coercive invocation of its
    obligation to remediate. In addition, the district court’s
    statement is incorrect insofar as its rests on the belief that
    a lawsuit is necessary under Illinois law to trigger an
    insurer’s duty to indemnify.
    Thus, because the district court erroneously concluded
    that Wausau’s duty to indemnify depended on its duty
    to defend, it never reached the key issue whether Keystone
    undertook its remedial action voluntarily. The court’s
    incorrect interpretation of Illinois law is enough to justify
    reversal.

    III. Conclusion
    In sum, we REVERSE the judgment of the district court
    and REMAND for further proceedings consistent with
    this opinion.
