    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF NEW MEXICO
    (D.C. NO. 2:11-CV-00329-WJ-LAM)
    Jennifer L. Collins (Robert J. Mroz with her on the briefs), Madison & Mroz,
    P.A., Albuquerque, New Mexico, for Appellants.
    Ken Slavin (Shelly W. Rivas, with him on the brief), Kemp Smith LLP, El Paso,
    Texas, for Appellee.
    Before TYMKOVICH, SEYMOUR, and GORSUCH, Circuit Judges.
    TYMKOVICH, Circuit Judge.
    I&W, Inc. owned a solution mining operation in Carlsbad, New Mexico.
    Its operations formed a cavern under its own property, which grew so large it
    infringed upon the subsurface property of the nearby Circle S Feed Store, LLC.
    This cavern, in turn, caused subsidence and damages to Circle S’s surface
    property. A New Mexico state court found I&W negligent and liable for damages
    its solution mining operations caused to Circle S’s property.
    I&W sought indemnification for the damages under its commercial general
    liability (CGL) insurance policies, which had been issued by Mid-Continent
    Casualty Company. Mid-Continent, in turn, sought a declaratory judgment in
    federal court that it was not required to indemnify I&W for damages awarded in
    the state court action. The district court granted summary judgment for
    Mid-Continent, holding that a provision of the policies’ Oil Industries Limitation
    Endorsement (Oil Endorsement) excluded coverage of the damages awarded in
    state court.
    Exercising jurisdiction under 28 U.S.C. § 1291, we AFFIRM IN PART and
    REVERSE IN PART. We agree that the Oil Endorsement excludes coverage
    under the excess/umbrella policies issued to I&W, but we hold the Endorsement
    does not affect coverage under the primary policies.
    I. Background
    -2-
    Starting in 1995, I&W engaged in solution mining on its property in
    Carlsbad, New Mexico. Solution mining involves injecting fresh water into an
    underground salt formation to dissolve the salt for the creation of brine water.
    Brine water is then pumped from the formation and sold for use in the oil and gas
    industries. This process inevitably creates an underground cavern. As a
    regulated entity of the New Mexico Oil Conservation Division (NMOCD), I&W
    was required to monitor subsidence and ensure that its brine removal was not
    washing out salt from deep within the salt bed.
    In 2008, the NMOCD required I&W to plug its last open well because the
    well posed a threat to “life and property.” App. 58. I&W’s operations caused an
    underground cavern to form under its own property and the adjacent property
    owned by Circle S, where Circle S operated its feed store, and caused subsidence
    and movement of Circle S’s land. Circle S filed suit against I&W in state court,
    alleging negligence, negligent trespass, nuisance, withdrawal of lateral and
    subjacent support, interference with and interruption of enjoyment of property and
    operation of business, and unjust enrichment. Circle S alleged that I&W’s actions
    caused damages to real property and structures and reduced the value of its
    property and business operations. At trial, experts testified that the cavern had
    increased in size over the years and the risk of the cavern collapsing was
    significant. Circle S also introduced evidence of the physical damages already
    caused to the structures located on its property. One expert opined that, as a
    -3-
    result of I&W’s actions, the value of Circle S’s property declined from $703,000
    to zero. The jury ultimately found I&W 100% negligent and awarded Circle S
    compensatory damages of $703,000 and punitive damages of $300,000. 1
    From 2000 to 2009, Mid-Continent issued to I&W separate CGL primary
    insurance policies for successive twelve-month periods. Mid-Continent also
    issued five separate excess/umbrella policies to I&W for successive twelve-month
    periods from June 1, 2000 to June 1, 2005 that were distinct from the primary
    policies. The excess/umbrella policies provided coverage beyond what was
    covered in the primary policies and required I&W to maintain underlying primary
    insurance. The excess/umbrella policies also expressly incorporated the terms of
    a standard-form “Oil Industries Limitation Endorsement,” which excluded
    coverage for damages caused by I&W’s subsurface operations.
    During the pendency of the state court litigation, Mid-Continent sought a
    declaratory judgment in federal court that it owed no duty to indemnify I&W
    under the insurance policies it issued to I&W between 2000 and 2009. Mid-
    Continent and Circle S both filed motions for summary judgment. The court
    rejected Mid-Continent’s assertion that the damages to the Circle S property were
    not caused by an “occurrence” within the meaning of the policy. The district
    court also held that the policy’s “intentional injury” exclusion did not apply.
    1
    I&W subsequently declared bankruptcy. Although I&W is joined in this
    case as a necessary party, the bankruptcy court gave Circle S the authority to
    control the litigation of this case.
    -4-
    Finally, the court concluded that the state court did not award damages for the
    property’s diminution in value, a type of damages not covered by the policy.
    Nevertheless, the district court granted summary judgment for Mid-Continent
    because it concluded that the Oil Endorsement excluded damages caused by
    I&W’s subsurface mining operations.
    Circle S filed a motion to alter or amend the final judgment, asserting that
    the district court erred in holding that the Oil Endorsement applied to the primary
    policies issued to I&W and requesting the court to clarify its holding. The district
    court declined to reconsider its holding, but declared that it would have found
    coverage but for the language in the Oil Endorsement. This appeal followed.
    II. Analysis
    Circle S argues for reversal on the grounds that the Oil Endorsement does
    not apply to the primary policies. Mid-Continent asks us to affirm the grant of its
    motion for summary judgment, noting that we may adopt alternate grounds for
    excluding coverage that the district court rejected. We agree with Circle S that
    the primary policies cover its damages, as we explain further below.
    We review a grant of summary judgment de novo. See Timmons v. White,
    
    314 F.3d 1229
    , 1232 (10th Cir. 2003). Because this is a diversity case, we
    ascertain and apply state law—in this case, New Mexico law. See McIntosh v.
    Scottsdale Ins. Co., 
    992 F.2d 251
    , 253 (10th Cir. 1993). Under New Mexico law,
    the construction of an insurance policy is a legal question that is reviewed de
    -5-
    novo. See United Nuclear Corp. v. Allstate Ins. Co., 
    285 P.3d 644
    , 647 (N.M.
    2012).
    We first explain why the Oil Endorsement exclusion does not apply to the
    primary policies. We then explain why the subsidence was a covered
    “occurrence” under the primary policies and that the state court’s damages
    calculation reasonably covers the physical damage to Circle S’s property. We
    conclude the district court erred in granting summary judgment for Mid-
    Continent.
    A. Application of Oil Endorsement Exclusion
    I&W purchased CGL policies from Mid-Continent to cover its general
    business operations. In addition to the primary policies, I&W purchased
    additional coverage in the form of excess/umbrella policies. As a part of this
    additional coverage, I&W and Mid-Continent agreed to an exclusion for damages
    arising from I&W’s subsurface operations, the so-called “Oil Industries
    Limitation Endorsement.” The Oil Endorsement, labeled Endorsement MU6057,
    operates to exclude coverage for damages caused by subsurface mining.
    Specifically, the Oil Endorsement states,
    It is agreed that this insurance does not apply to:
    1. . . . .
    2. Loss of, damage to, or loss of use of property directly
    or indirectly resulting from subsidence caused by
    subsurface operations of the Insured.
    3. Removal of, loss of, or damage to subsurface oil, gas
    or any other substance, the property of others.
    -6-
    App. 574 (emphasis added). The district court reasoned that subsection A.2
    clearly applied to exclude the damages to Circle S’s property caused by I&W’s
    solution mining operations. The court applied the Oil Endorsement to exclude all
    coverage under the primary and excess/umbrella policies, even though Mid-
    Continent did not argue for such a broad exclusion before the district court.
    Circle S argues that the Oil Endorsement does not exclude coverage under
    the primary policies because the primary policies do not incorporate the Oil
    Endorsement. We agree.
    The primary policies and excess/umbrella policies issued to I&W are
    distinct sets of policies, serve different purposes, and incorporate different forms
    and endorsements. An excess policy provides secondary coverage only after the
    primary coverage limits have been exhausted. An umbrella policy, meanwhile,
    “provide[s] primary coverage for risks that the underlying policy does not cover.”
    15 Steven Plitt et al., Couch on Insurance § 220:32 (3d ed. 2013). The term
    “umbrella” does not mean that every one of the umbrella policy’s terms is
    applicable to an underlying primary policy—the umbrella policy is a separate and
    distinct policy. See Commercial Union Ins. Co. v. Walbrook Ins. Co., 
    7 F.3d 1047
    , 1053 (1st Cir. 1993) (“Umbrella policies differ from standard excess
    insurance policies in that they are designed to fill gaps in coverage both vertically
    (by providing excess coverage) and horizontally (by providing primary
    -7-
    coverage).”). Because excess and umbrella policies are distinct from underlying
    primary policies, their endorsements are not automatically incorporated into and
    do not affect the terms of the primary policies. Cf. Empire Fire & Marine Ins.
    Co. v. Guaranty Nat’l Ins. Co., 
    868 F.2d 357
    , 363 (10th Cir. 1989) (declining to
    apply one policy’s endorsement to other policies because the endorsement does
    not “purport to limit or delete clauses in other policies”), overruled on other
    grounds by Carolina Cas. Ins. Co. v. Yeates, 
    584 F.3d 868
    (10th Cir. 2009).
    Mid-Continent issued excess/umbrella policies to I&W that contain policy
    numbers distinct from the primary policies and for which Mid-Continent collected
    separate premiums. And each of the excess/umbrella policies issued to I&W
    incorporates the Oil Endorsement into its terms. The primary policies, however,
    list several forms and endorsements incorporated into the policies; none of them
    contain Endorsement MU6057. Because the express terms of the policies limit
    the application of the Oil Endorsement to the excess/umbrella policies, the district
    court erred in concluding that the Oil Endorsement applied to exclude all
    coverage under the primary policies. 2
    2
    Mid-Continent does not attempt to argue that the Oil Endorsement
    excludes coverage under the primary policies, and conceded as much at oral
    argument. Instead, it asserts Circle S cannot make the argument on appeal
    because Circle S did not argue against the Endorsement’s applicability in the
    district court. But Circle S had no opportunity to raise this issue to the court
    because Mid-Continent did not address it in its motion for summary judgment and
    the district court ruled on it sua sponte. Because Circle S was not on notice that
    it would have to argue against the applicability of the Endorsement to the primary
    (continued...)
    -8-
    Circle S also asks us to find the Oil Endorsement does not exclude
    coverage under the excess/umbrella policies, even though these policies
    incorporate the Oil Endorsement. Circle S contends the district court erred in its
    interpretation of subsection A.2 to exclude coverage for solution mining because
    the provisions of the Oil Endorsement are ambiguous, in that they seemingly
    apply only to subsurface operations related to oil and gas extraction, rather than
    to solution mining. It argues the ambiguity should be construed against the
    insurer. See United 
    Nuclear, 285 P.3d at 648
    .
    We agree with the district court that the plain language of the Oil
    Endorsement is not ambiguous and expressly applies to I&W’s solution mining
    operations. The specific language, “subsurface operations of the Insured,”
    plainly applies to I&W’s business and thus excludes coverage for damages to
    Circle S’s property under the excess/umbrella policies.
    In sum, the district court should not have applied the Oil Endorsement to
    exclude primary coverage for damages caused by I&W’s solution mining
    operations. But the Oil Endorsement does exclude coverage under the
    excess/umbrella policies.

    (...continued)
    policies, the argument is not considered waived. See Kannady v. City of Kiowa,
    
    590 F.3d 1161
    , 1170–71 (10th Cir. 2010).
    -9-
    B. Other Contract Provisions
    Since we conclude the Oil Endorsement does not bar coverage under the
    primary policies, we must consider the district court’s resolution of the remaining
    issues. In its order, the district court stated that, but for the Oil Endorsement, it
    would have found coverage for the damages caused to Circle S’s property, in
    three steps: (1) the subsidence I&W caused was an “occurrence” within the
    meaning of the policies; (2) the policies’ “intentional injury” exclusion did not
    apply to exclude coverage; and (3) the damages awarded to Circle S were for a
    “physical injury to tangible property,” which is covered, rather than for pure
    diminution in value, which is not.
    We address each in turn.
    1. “Occurrence”
    Mid-Continent argues the district court was incorrect to conclude that the
    damage caused by the underground cavern and subsidence was an “occurrence”
    within the meaning of the primary policies.
    CGL policies provide coverage for the insured’s “tort liability for physical
    injury to the person or property of others,” but not for the insured’s “contractual
    liability which merely causes economic losses.” 9A Steven Plitt et al., Couch on
    Insurance § 129:4 (3d ed. 2013). They “are intended to provide coverage only for
    events which are fortuitous, unforeseeable events, and not for the foreseeable
    results of an insured’s deliberate conduct . . . .” 
    Id. -10- The
    primary policies issued to I&W require coverage for “property
    damage” caused by an “occurrence” within the coverage territory. The policies
    define an occurrence as an “accident, including continuous or repeated exposure
    to substantially the same general harmful conditions.” App. 318. Because the
    policies do not define “accident,” we look to state law to define this term.
    Employers Mut. Cas. Co. v. Bartile Roofs, Inc., 
    618 F.3d 1153
    , 1173 (10th Cir.
    2010). Under New Mexico law, the term “accident” in an insurance policy
    “expresses the thought of an event occurring without design or purpose, or
    unintentionally on the part of the [insured]. Given the latter meaning, it does not
    negative the idea of negligence on the part of one whose physical act the
    occurrence follows.” King v. Travelers Ins. Co., 
    505 P.2d 1226
    , 1229 (N.M.
    1973) (internal quotation marks and citation omitted). It is “an unexpected,
    unforeseen, or undesigned happening or consequence from either a known or an
    unknown cause.” Vihstadt v. Travelers Ins. Co., 
    709 P.2d 187
    , 188 (N.M. 1985)
    (quoting 
    King, 505 P.2d at 1229
    –30).
    Mid-Continent argues that there was no “occurrence” under the policies
    because I&W deliberately created the underground cavern that damaged Circle
    S’s property through intentional conduct. According to Mid-Continent’s
    interpretation of what constitutes an “occurrence,” the relevant question is
    whether the act giving rise to the harm was deliberate, rather than whether the
    resulting injury was deliberate. Mid-Continent maintains that, because the
    -11-
    removal of brine water, whether done correctly or negligently, inevitably results
    in an underground cavity, I&W’s intentional removal of brine water and
    knowledge of the resulting cavity are enough to establish deliberateness. See
    Greystone Constr., Inc. v. Nat’l Fire & Marine Ins. Co., 
    661 F.3d 1272
    , 1283
    (10th Cir. 2011) (“[A] deliberate act, performed negligently, is an accident if the
    effect is not the intended or expected result; that is, the result would have been
    different had the deliberate act been performed correctly.”). Mid-Continent urges
    us to adopt a “natural and probable consequences” approach to the definition of
    accident. This approach typically excludes coverage for injuries resulting from
    the negligent acts of the insured. See, e.g., Bartile 
    Roofs, 618 F.3d at 1174
    (interpreting Utah and Wyoming law).
    But under the majority approach, the insured’s act is not accidental only if
    the insured “intended both the act and to cause some kind of injury or damage.
    Intent to cause the injury or damage can be actual or it can be inferred from the
    nature of the act when the consequences are substantially certain to result from
    the act.” Thomas v. Benchmark Ins. Co., 
    179 P.3d 421
    , 431 (Kan. 2008); see also
    
    Greystone, 661 F.3d at 1285
    (“[T]he term ‘occurrence’ excludes from coverage
    only those damages that the insured knew would flow directly and immediately
    from its intentional act.” (internal quotation marks omitted) (interpreting
    Colorado law)); Sena v. Travelers Ins. Co., 
    801 F. Supp. 471
    , 476 (D.N.M. 1992)
    (holding the injury must be the “direct, natural result” of an “inherently harmful”
    -12-
    act for a court to find the injury outside the scope of coverage (citing 
    Vihstadt, 709 P.2d at 189
    )); Robert H. Jerry & Douglas R. Richmond, Understanding
    Insurance Law § 63C(b) (5th ed. 2012) (describing that a majority of jurisdictions
    require an intent to act and to cause some kind of injury for the damage to be
    excluded); Eric Mills Holmes, Appleman on Insurance 2d (archive file) § 117.4
    (“For purposes of determining whether recovery can be had under an ‘accident’
    provision of a liability policy, the resulting damage can be unintentional and
    therefore accidental even though the original acts were intentional.”); 
    id. (“The majority
    insurance rule is that loss resulting from ordinary negligence of an
    insured or the insured’s agent may be considered as injury or damage caused by
    ‘accident’ . . . .”).
    The New Mexico Supreme Court endorsed the majority approach in the
    context of defining an “intentional injury” exclusion. Knowles v. United Servs.
    Auto. Ass’n, 
    832 P.2d 394
    , 397 (N.M. 1992). 3 The court held that the insurance
    policy at issue, which excluded “damage expected or intended” by the insured,
    “excludes harm of the same general type as the insured intended.” 
    Id. The court
    reasoned that this approach “balances the policy of construing ambiguous clauses
    3
    The inquiry into whether an injury is accidental informs the court’s
    determinations as to whether an “occurrence” is present and whether the
    “intentional injury” exclusion applies. See Hartford Fire Ins. Co. v. Gandy
    Dancer, LLC, 
    864 F. Supp. 2d 1157
    , 1197 n.13 (D.N.M. 2012), other grounds
    reconsidered in CIV 10-0137 JB/RHS, 
    2013 WL 5934489
    (D.N.M. Aug. 30,
    2013).
    -13-
    in favor of the insured against an insurance company’s right to not insure against
    harm deliberately caused by the insured.” 
    Id. at 397–98.
    The court explicitly
    rejected the “natural and probable consequences” approach to determining
    whether an injury is intended. See 
    id. at 397.
    Based on this legal framework, the damages I&W’s negligence caused to
    Circle S’s property are within the scope of coverage of the primary policies
    because I&W neither intended the injuries to Circle S’s property nor knew that
    injuries were likely to result. No evidence in the record suggests I&W knew that
    damages to Circle S’s property “would flow directly and immediately from its
    intentional act.” 
    Greystone, 661 F.3d at 1285
    . To the contrary, the record
    discloses I&W was not aware that its underground cavern had grown dangerously
    large or that the cavern infringed upon Circle S’s subsurface property. All
    solution mining causes an underground cavern to form, but it is not true that
    subsidence or damages to an adjoining property and its surface structures are
    “substantially certain to result from” all solution mining operations. 
    Thomas, 179 P.3d at 431
    . Generalized knowledge that solution mining causes cavern growth is
    not enough to establish constructive intent. Without evidence of I&W having
    actual or constructive intent to cause a dangerously large cavern to form in the
    course of its solution mining operations, we must conclude that the damages were
    caused by an “occurrence” within the meaning of the primary policies.
    -14-
    The rule Mid-Continent has presented to us would swallow the insurance.
    Every harm flowing from intentional acts, whether driving a tractor or drilling a
    well, would not be covered because the tortfeasor intended to drive the tractor or
    drill the well. This narrow scope of coverage is inconsistent with New Mexico
    law. See, e.g., 
    King, 505 P.2d at 1229
    (“[A]n insurance policy designed to
    compensate for damages suffered by ‘accidental means’ is no less effective when
    the damages result from negligence.”).
    In support of its position that the relevant inquiry is whether the insured’s
    act was deliberate, Mid-Continent points to Red Ball Leasing, Inc. v. Hartford
    Accident & Indem. Co., 
    915 F.2d 306
    (7th Cir. 1990). In Red Ball, the Seventh
    Circuit held that the insured’s intentional repossession of trucks to which it
    believed it held a right of repossession did not constitute an “occurrence” under
    the policy. The insured had argued that, because it believed it had the right to
    repossession, its tortious conversion of the trucks was accidental. The court
    disagreed, concluding that the resulting damage of the insured’s act—
    repossession of the trucks—was intentional. Even though the insured’s
    negligence in its accounting procedures caused it to seek repossession of the
    trucks, the court held that, “whether prompted by negligence or malice, (1)
    appellant’s acts were committed consciously and deliberately, without the
    unexpected intervention of any third force, and (2) the likely (and actual) effect of
    those acts was well within appellant’s foresight and anticipation.” 
    Id. at 310
    -15-
    (internal quotation marks omitted). That the insured was unaware of the legal
    consequences of its volitional act was not material.
    Unlike the insured in Red Ball, the result of I&W’s solution mining was not
    “well within” I&W’s “foresight and anticipation.” I&W intended to conduct
    solution mining in its subsurface property and anticipated that an underground
    cavern would form. But the resulting damage—infringement on Circle S’s
    subsurface property, subsidence, and damage to surface structures—was not the
    anticipated result. There is no allegation that I&W intentionally infringed upon
    Circle S’s property under a mistaken belief that it had a right to do so. The
    infringement was accidental and the result of I&W’s negligence.
    The district court correctly concluded that the damages to Circle S’s
    property were caused by an “occurrence” and are thus covered under the primary
    policies.
    2. “Intentional Injury” Exclusion
    Mid-Continent next argues that the “intentional injury” exclusion applies to
    exclude coverage under the policies.
    The primary policies issued to I&W exclude from coverage “intentional
    injuries” caused by the insured. As an initial matter, the legal framework for
    determining whether an “occurrence” is present also controls whether a CGL
    policy’s “intentional injury” exclusion applies. As explained above, New Mexico
    construes an “intentional injury” provision “to exclude harm of the same general
    -16-
    type as intended by the insured.” 
    Knowles, 832 P.2d at 398
    . In Knowles, the
    court held that the exclusion applied because the insured erected a gate on a road
    across his property with the intent to exclude others from accessing the road.
    This interfered with another individual’s right to access an easement, and this
    individual sued for wrongful eviction. Even though the insured did not intend to
    commit the intentional tort of wrongful eviction, the court applied the “intentional
    injury” exclusion because the harm alleged in the complaint was of the same
    general type expected or intended by the insured in erecting the gate.
    But here, as we have described, the harm caused to Circle S was not
    expected or intended by I&W. There is no evidence to conclude that I&W
    expected or intended the underground cavern to grow dangerously large or
    infringe upon Circle S’s property. The district court was correct to hold the
    “intentional injury” exclusion does not apply.
    3. Diminution in Value Damages
    Lastly, Mid-Continent argues that the district court erred in finding the
    damages awarded to Circle S were for “property damage” within the meaning of
    the policies. The company contends that the damages awarded were for the
    diminution in value of Circle S’s property. Because diminution in value is not
    “property damage” within the meaning of the policies, Mid-Continent contends,
    the court erred in finding coverage for these damages. We disagree.

    Like all standard CGL policies, the primary policies at issue in this case
    cover “damages because of . . . ‘property damage’ to which this insurance
    applies.” App. 305 (emphasis added). The policy defines “property damage” as
    “physical injury to tangible property, including all resulting loss of use of that
    property.” 
    Id. at 319.
    Under a CGL policy, intangible losses, such as diminution
    in value, do not constitute “property damage” within the meaning of the policy.
    See Hartford Accident & Indem. Co. v. Pac. Mut. Life Ins. Co., 
    861 F.2d 250
    , 254
    (10th Cir. 1988); see also Goodstein v. Cont’l Cas. Co., 
    509 F.3d 1042
    , 1054 (9th
    Cir. 2007) (“[D]iminution in value does not alone constitute ‘property damage’
    where the policy language requires ‘physical injury to tangible property.’”). 4
    Damages that result from “property damage” within the meaning of a CGL
    policy may be measured according to the diminution in value of the property, as
    long as the diminution in value is attributable to the covered damage. See, e.g.,
    Mid-Continent Cas. Co. v. Acad. Dev., Inc., 476 F. App’x 316, 319 (5th Cir.
    2012) (“A damages because of . . . ‘property damage’ provision in a CGL policy
    includes recovery sought for economic losses, such as diminution in value, that
    are ‘attributable’ to property damage.”); Helm v. Bd. of Cnty. Comm’rs, Teton
    4
    Before revisions to the standard CGL policy form in 1973, CGL policies
    typically covered losses for diminution in value as an “injury . . . to property.”
    The revisions made in 1973 limited coverage to physical injury to or loss of use
    of tangible property. See 
    Hartford, 861 F.2d at 254
    (“The definition of property
    damage incorporated into the standard CGLP form by the 1973 revision and found
    in the umbrella policy here, was intended to preclude coverage for intangible
    injuries such as diminution in value.”).

    directly from the damage to the property occasioned by the builders’ installation
    of a defect and/or from the loss of use of the property. This injury falls squarely
    within the plain language of the insurance policy exclusion.”); 9 Steven Plitt et
    al., Couch on Insurance § 126:38 (3d ed. 2013) (“There are two views regarding
    whether the diminution in value of tangible property constitutes property damage.
    One view holds that such damages are compensable only when they are the result
    of physical damage. . . . Other courts hold to the view that the diminution of value
    of tangible property constitutes ‘property damage’ in and of itself.”); Jeffrey E.
    Thomas, New Appleman on Insurance Law § 18.02 (“Because the insuring
    agreement refers to liability imposed ‘because of . . . property damage,’ an
    economic loss that causally follows from a direct physical injury to tangible
    property or a loss of use of tangible property is within the coverage of the
    CGL.”).
    Mid-Continent points to our decision in Hartford as contrary authority.
    There, a sub-contractor installed a defective exterior wall system in a building.
    The system failed, causing physical damage to parts of the building and requiring
    the building owner to undertake a major restoration project and replace parts of
    the system. The district court had to construe two separate policies: a pre-1973
    primary policy and an excess/umbrella policy incorporating the 1973 revisions.
    The district court concluded, with respect to the primary policy, that the correct
    -19-
    measure of damages that a defective integral part of a building caused to the
    whole is the lesser of the diminution in market value of the building or the costs
    of restoration plus losses for deprivation of use. 
    Hartford, 861 F.2d at 252
    .
    We disagreed, holding that, because the primary policy excluded coverage
    for repair or replacement of a faulty work product but permitted recovery of
    diminution in value damages, the correct measure of damages was the diminution
    in value minus the costs of restoration of the wall system. 
    Id. at 254.
    But,
    because the excess/umbrella policy incorporated the 1973 revisions, the
    excess/umbrella policy did not cover damages for the diminution in value of the
    building. 
    Id. Finally, we
    concluded the policies did not cover any consequential
    damages because the policies provided coverage only for damages caused by
    “property damage to which this insurance applies.” 
    Id. at 254–55
    (emphasis in
    original). Because the insured’s defective work product was not property damage
    to which the insurance applied, any consequential damages were not covered.
    Mid-Continent asks us to read our decision in Hartford to exclude coverage
    for diminution in value arising out of a covered “physical injury to tangible
    property” because we found no coverage for diminution in value of the building
    even though there was accompanying physical damage. See Scott Turner,
    Insurance Coverage of Construction Disputes § 6:28 (2d ed.) (commenting on
    Hartford and other similar cases) (“After the physical injury qualification was
    added in the 1973 revision of the standard policies, a few courts held that
    -20-
    diminution in value did not satisfy the ‘physical injury to the real property’
    requirement. That analysis misses the point. The physical injury under this
    approach is not the diminution in value itself. Diminution in value is only the
    measure of damages.”).
    Such a broad reading of Hartford, however, is unwarranted. In Hartford,
    we found no underlying “property damage” within the meaning of the
    excess/umbrella policy, which incorporated the 1973 revisions. Although there
    was physical damage to other parts of the building, as we explained above, those
    damages were not covered because they did not derive from “property damage to
    which the insurance applie[d].” 
    Hartford, 861 F.2d at 255
    . Consequently, there
    was no “property damage” from which diminution in value damages could have
    arisen. We declined coverage under the excess/umbrella policy at issue in
    Hartford because the damages were pure diminution in value damages,
    unconnected to any form of covered “property damage.” See 46 C.J.S. Insurance
    § 1406 (“While a diminution in the value of property caused by insured’s faulty
    workmanship does not constitute property damage, a diminution in the value of
    property caused by physical damage to the property constitutes property
    damage.”); New Hampshire Ins. Co. v. Vieira, 
    930 F.2d 696
    , 701 (9th Cir. 1991)
    (“Diminution in value and cost of repair are not two separate harms—they are two
    different ways of measuring the same harm.”). Therefore, we cannot read
    -21-
    Hartford to exclude coverage for diminution in value that arises from covered
    property damage.
    In the underlying lawsuit in this case, the state trial court awarded damages
    for the diminution in value of Circle S’s property caused by physical injury to the
    property. The judge instructed the jury that, if it found damages were
    appropriate, the proper measure of damages was the difference in value of Circle
    S’s property before and after the subsidence occurred, since the property had little
    or no resale value for surface operations. The figure awarded, $703,000, matches
    the figure an expert testified was the diminution in market value of the property.
    But the figure awarded reasonably measures the damages arising out of the
    physical injury to the property.
    In sum, we conclude that the district court was correct: the primary
    policies cover the damages awarded to Circle S. The loss of value of Circle S’s
    property stemmed directly from a physical injury to Circle S’s real property. It is
    uncontested the subsidence and cavern growth in Circle S’s subsurface property
    qualifies as a physical injury to Circle S’s property. This physical injury resulted
    in a danger of collapse of Circle S’s property, which renders the property
    completely valueless. Under these circumstances, diminution in value damages
    constitute “damages because of . . . ‘property damage’ to which this insurance
    applies.” App. 305.

    III. Conclusion
    In sum, we AFFIRM IN PART and REVERSE IN PART. We agree with
    the district court that the Oil Endorsement excludes coverage under the
    excess/umbrella policies. But we hold that the Oil Endorsement does not exclude
    coverage that otherwise exists under the primary policies. We REVERSE the
    district court’s ruling that Circle S’s cross-motion for summary judgment and
    Mid-Continent’s motion on punitive damages were moot. We REMAND for
    further proceedings consistent with this opinion.
