SMITH, Circuit Judge.
       Land O' Lakes, Inc. ("Land O' Lakes") sued two of its insurers, Employers
Mutual Liability Insurance Company of Wausau1 ("Wausau") and The Travelers
Indemnity Company ("Travelers"), seeking payment of defense costs and
indemnification under commercial general liability (CGL) policies that Wausau and
Travelers (collectively, "the Insurers") issued in connection with an action that the
Environmental Protection Agency (EPA) brought against Land O' Lakes under the
Comprehensive Environmental Response, Compensation, and Liability Act of 1980,
42 U.S.C. § 9601 et seq. (CERCLA). The district court2 granted summary judgment
to the Insurers, concluding that (1) Minnesota's six-year statute of limitations on
contract actions barred Land O' Lakes's claim that the Insurers breached their duty to
defend and (2) the owned-property exclusion in the CGL policies that the Insurers
issued relieved them of any duty to indemnify Land O' Lakes for the costs of the
EPA-mandated cleanup. Land O' Lakes appeals, and we affirm the judgment of the
district court.

                                 I. Background
       Land O' Lakes, a member-owned agricultural cooperative, merged with
Midland Cooperatives, Inc., ("Midland") in January 1982. Midland operated an oil
refinery in Cushing, Oklahoma, from 1943 until 1977, when the facility was sold to
Hudson Oil Refinery Company ("Hudson Oil"). Hudson Oil, Midland's successor,
abandoned the refinery in 1982 and went bankrupt in 1984. Land O' Lakes acquired
Midland in 1982, including the now dormant refinery. The EPA eventually targeted
Hudson Oil in a cleanup action at the refinery site. In addition, the Oklahoma
Department of Environmental Quality (ODEQ) subjected the site to ongoing

of Minnesota.

monitoring. Hudson Oil cleaned up the refinery site for ten years, but ceased after
exhausting its funds, and in 1994, the EPA released Hudson Oil from further cleanup
obligations at the refinery site.

       In 1998, the EPA and the ODEQ conducted a joint inspection of the refinery
site and detected a number of serious problems involving the release of hazardous
materials. To address these immediate threats to human health and the environment,
EPA contractors began an emergency removal action in late 1998, and in July 1999,
the EPA placed the refinery site on the National Priorities List, thus designating the
refinery as a Superfund site under CERCLA. From 2001 to 2003, the EPA conducted
a second, non-time-critical removal action to clean up additional pollution on the site.

       In January 2001, the EPA sent Land O' Lakes a Special Notice Letter ("the
2001 PRP Letter"), informing Land O' Lakes that based on Midland's past ownership
of the refinery site and Land O' Lakes's later acquisition of Midland, the EPA
considered Land O' Lakes a Potentially Responsible Party (PRP) under CERCLA and
thus potentially liable for cleanup costs at the refinery site. See 42 U.S.C. § 9607(a);
40 C.F.R. § 304.12(m) (defining "potentially responsible party"). Under CERCLA,
a PRP may be required to pay the costs of cleaning up a Superfund site that it or its
predecessors previously owned. 42 U.S.C. § 9607(a). The 2001 PRP Letter, among
other things, (1) demanded that Land O' Lakes pay the roughly $8.9 million in costs
already incurred by the EPA in cleaning up the refinery site in the emergency and
non-time-critical actions;3 (2) invited Land O' Lakes to enter into negotiations with
the EPA for the performance of a Remedial Investigation and Feasibility Study
(RI/FS) at the refinery site; and (3) provided general and refinery-site-specific
information for purposes of negotiations with the agency. The EPA sent a draft

       The parties agree that the $8.9 million in removal costs attributable to the
EPA's emergency and non-time-critical removal actions is not covered under the CGL
policies that the Insurers issued.

                                          -3-
Administrative Order on Consent (AOC) for conducting the RI/FS along with the
2001 PRP Letter.

      In March 2001, Land O' Lakes responded to the 2001 PRP Letter by asserting
that Hudson Oil, not Midland, caused any contamination at the refinery site. Thus,
Land O' Lakes asserted that it bore no responsibility for the cleanup costs. Land O'
Lakes also refused to pay the $8.9 million in past cleanup costs that the EPA incurred
and to participate in or pay for an RI/FS.

      Despite Land O' Lakes's denial of responsibility for cleanup at the refinery site,
Land O' Lakes notified the Insurers of the EPA's claims and sought a defense and
indemnification under various CGL policies that the Insurers issued to Land O' Lakes
and Midland. In November 2001, Wausau declined to defend Land O' Lakes,
concluding that the 2001 PRP Letter was not a covered "suit" under the CGL policies.
Land O' Lakes challenged this determination by letter in January 2002, noting that
most courts considering the issue had ruled "that the duty to defend is triggered by
an EPA demand letter." Land O' Lakes contended that Wausau's actions amounted to
"a declination of coverage and a breach of [Wausau's] duty to defend." For the next
six years, however, Land O' Lakes took no further action to challenge Wausau's
denial of defense and indemnification obligations under the policies.

       Travelers also declined to defend Land O' Lakes after receiving notice of the
2001 PRP Letter. Travelers concluded that, because its CGL policies had been issued
to Land O' Lakes prior to Land O' Lakes's acquisition of Midland in January 1982,
those CGL policies would not provide any coverage to Midland before Land O' Lakes
acquired Midland. For the next seven years, Land O' Lakes took no further action to
challenge Travelers's denial of defense and indemnification obligations under the
policies.




                                          -4-
       Meanwhile, without Land O' Lakes's participation, the EPA continued its
cleanup activities at the refinery site, completing its non-time-critical removal action
in June 2003. From 2004 to 2007, the ODEQ, on behalf of the EPA, completed an
RI/FS that outlined the contamination on the site and proposed alternatives to finally
complete the cleanup. In November 2007, the EPA issued a Record of Decision
(ROD) in which it selected an approach to completing the cleanup of the site. The
ROD described the history of activities on the site, evaluated the contamination found
at the site, listed and compared the alternative approaches for remedying the
contamination, and ultimately selected a remedy to "treat[] and/or remove[] the source
materials constituting principal threats at the site." The ROD estimated that the
selected remedy would cost $9.65 million.

       The EPA sent Land O' Lakes a second Special Notice Letter in February 2008
("the 2008 PRP Letter"), inviting Land O' Lakes to enter negotiations regarding the
continued cleanup activities at the refinery site. The EPA also demanded that Land
O' Lakes reimburse it for approximately $21 million in prior cleanup expenditures at
the site. Included with the 2008 PRP Letter was a draft consent decree and a draft
Remedial Design/Remedial Action plan (RD/RA) for implementing the cleanup
remedy the EPA had earlier selected in the ROD.

       In May 2008, Land O' Lakes responded to the EPA by reiterating its earlier
denial. It contended that Midland had caused any contamination at the site, refused
to reimburse the EPA for past cleanup costs, and declined to participate in or pay for
any future cleanup activities. Land O' Lakes notified the Insurers of the 2008 PRP
Letter, and it again asked for a defense and indemnification. The Insurers again
denied that they had any obligation to defend or indemnify Land O' Lakes in
connection with the cleanup of the refinery site.

     In January 2009, the EPA rejected Land O' Lakes's denial of responsibility for
remediation at the refinery site and issued a Unilateral Administrative Order (UAO),

                                          -5-
                                           5
directing Land O' Lakes to implement the cleanup remedy the EPA had selected in
the ROD. The UAO ordered Land O' Lakes to "perform a remedial design for the
remedy described in the [ROD]" and to "implement the design by performing a
remedial action." In February 2009, shortly after receiving the UAO, Land O' Lakes
informed the EPA that it would comply with the agency's directives regarding the
refinery site. Although Land O' Lakes objected to several details, it initiated the
cleanup activities dictated in the UAO. Land O' Lakes hired contractors to implement
the selected remedy, and in November 2010, the EPA issued a report indicating that
the site had been cleaned up in accordance with the ROD. At present, the remediation
is largely complete. The site will, however, remain subject to periodic inspections by
the EPA or the ODEQ.

       After initiating its cleanup efforts, Land O' Lakes filed a breach-of-contract
action against the Insurers. Land O' Lakes demanded reimbursement of the costs it
had incurred in defending the EPA action and a declaration that the Insurers were
required to indemnify Land O' Lakes for its costs in cleaning up the refinery site. The
Insurers moved for summary judgment, which the district court granted. With respect
to Land O' Lakes's duty-to-defend claim, the court concluded that (1) the EPA's 2001
PRP Letter was a suit for arguably-covered damages under the relevant CGL policies;
(2) the Insurers' refusal in 2001 to defend against the EPA's suit constituted a breach
of their duty to defend under the respective CGL policies; (3) this breach triggered
the six-year limitations period on contract actions under Minnesota law;4 and (4)
because Land O' Lakes did not file its lawsuit against the Insurers until 2009, the
duty-to-defend claim was untimely. With respect to Land O' Lakes's duty-to-
indemnify claim, the court concluded that the owned-property exclusion in the CGL


      4
        None of the parties challenge the district court's determination that
Minnesota's six-year statute of limitations applies to Land O' Lakes's claim that the
Insurers breached their duty to defend. See Minn. Stat. § 541.05, subd. 1(1)
(establishing a six-year limitations period for contract actions).

                                         -6-
                                          6
policies at issue precluded coverage for Land O' Lakes's costs to comply with the
EPA-mandated cleanup.

                                    II. Discussion
       In this appeal, Land O' Lakes argues that the 2008 PRP Letter constitutes a
"suit," but the 2001 PRP Letter was not a "suit"—and, thus, the Minnesota statute of
limitations does not bar its claims. It contends that the 2001 and 2008 letters were
distinct claims and have separate accrual dates as it relates to the statute of
limitations. Land O' Lakes also argues that the owned property exclusions to its
insurance policies are inapplicable because the refinery cleanup was conducted to
address an existing threat. We review de novo a district court's interpretation of an
insurance contract and its decision to grant summary judgment. Face, Festivals &
Concert Events, Inc. v. Scottsdale Ins. Co., 632 F.3d 417, 419 (8th Cir. 2011).

                             A. Effect of 2001 PRP Letter
       Land O' Lakes first argues that the district court erred in holding that the 2001
PRP Letter triggered the Insurers' duty to defend and thus that Minnesota's six-year
statute of limitations on contract actions barred Land O' Lakes's claims. An insurer's
duty to defend is generally determined based on the allegations in the underlying
complaint, and the duty extends to every claim that arguably falls within the scope of
coverage provided under the relevant insurance policy. Wooddale Builders, Inc. v.
Md. Cas. Co., 722 N.W.2d 283, 302 (Minn. 2006). This is true regardless of the
merits of the claims asserted. Id. Land O' Lakes argues that the 2001 PRP Letter did
not trigger the Insurers' duty to defend because the 2001 PRP Letter was not a "'suit'
seeking damages because of 'property damage,'" as the CGL policies define those
terms. In other words, according to Land O' Lakes, the 2001 PRP Letter was not a suit
for arguably-covered damages. Rather, according to Land O' Lakes, the 2001 PRP
Letter was nothing more than an "invitation to participate in an investigation" into
whether remediation would be necessary at the refinery site. We disagree.

                                           7
        The district court applied Minnesota choice of law rules to determine whether
Minnesota or Oklahoma law governed the insurance contract. The court determined
that Minnesota law applied to the Travelers Insurance policy because Travelers issued
the policy before Land O' Lakes acquired the Oklahoma refinery. Also, the court
determined that Oklahoma law applied to the Wausau policy because Wausau issued
it specifically to cover the refinery. The Minnesota Supreme Court has concluded that
a PRP letter is a "suit" as that term is used in various CGL policies. See SCSC Corp.
v. Allied Mut. Ins. Co., 536 N.W.2d 305, 315 (Minn. 1995), overruled on other
grounds by Bahr v. Boise Cascade Corp., 766 N.W.2d 910, 919 (Minn. 1995). The
Oklahoma Supreme Court has not yet addressed the issue. Based on its assessment,
the district court determined that the Oklahoma Supreme Court would rule consistent
with Minnesota. Land O' Lakes, Inc. v. Emp'rs Mut. Liab. Ins. Co. of Wis., 846 F.
Supp. 2d 1007, 1019–22 (D. Minn. 2012). Neither Land O' Lakes nor the Insurers
contest this determination on appeal, and we therefore adopt the district court's
conclusion. See Hallquist v. United Home Loans, Inc., 715 F.3d 1040, 1046 (8th Cir.
2013) ("Claims not raised in an opening brief are deemed waived." (Quotations and
citations omitted)).

       Land O' Lakes takes issue with the district court's conclusion that the 2001 PRP
Letter was a "suit" for arguably-covered damages for purposes of the CGL policies
that the Insurers issued. But contrary to Land O' Lakes's characterization of the 2001
PRP Letter, it was not simply an invitation to participate in an investigation. The 2001
PRP Letter marked the beginning of an adversarial administrative process that
ultimately sought to impose liability upon Land O' Lakes for remediation costs
associated with the refinery site. The 2001 PRP Letter served purposes in addition to
requesting Land O' Lakes's voluntary participation. Specifically, the 2001 PRP letter:
(1) notified Land O' Lakes of its "potential liability under CERCLA . . . with respect
to" the refinery site; (2) informed Land O' Lakes that a "60-day formal negotiation
period" would commence upon Land O' Lakes's receipt of the Letter; (3) asked Land
O' Lakes "to participate in formal negotiations" toward a settlement and future

                                          -8-
                                           8
response actions at the refinery site, including an RI/FS to determine the nature and
extent of the contamination and an RD/RA to design and implement the EPA's
selected remedy; (4) advised Land O' Lakes that it was "potentially liable for" the
payment of necessary future investigation, remediation, and maintenance costs; and
(5) warned Land O' Lakes that if it did not agree to perform or finance the necessary
actions after good-faith negotiations, the EPA would commence cleanup and issue an
administrative order or pursue civil litigation for reimbursement of its costs. The 2001
PRP Letter also cautioned that failure to comply could result in fines under CERCLA
of up to $27,500 per day or treble damages. Included with the 2001 PRP Letter was
the draft AOC, which alleged that contamination originating at the refinery site had
already damaged off-site property and might continue to do so. As the district court
noted, the 2001 PRP Letter was "not a polite invitation from the EPA to engage in
conversation." Emp'rs Mut. Liab., 846 F. Supp. 2d at 1020. Taken as a whole, the
information relayed in the 2001 PRP Letter alerted Land O' Lakes that a suit for
arguably-covered damages had commenced.

       In fact, Land O' Lakes originally took the position that it now attempts to
disavow, namely, that the 2001 PRP Letter was a suit for arguably-covered damages.
Specifically, Land O' Lakes advised in a November 2001 letter to Wausau that "the
majority rule is that the duty to defend is triggered by an EPA demand letter" and
further stated that Land O' Lakes considered Wausau's determination to the contrary
"a declination of coverage and a breach of [Wausau's] duty to defend." It is apparent
that Land O' Lakes itself considered the 2001 PRP Letter a suit for arguably-covered
damages and the Insurers' refusal to defend a breach of their duty.

       Alternatively, Land O' Lakes contends that even if the 2001 PRP Letter
constituted a suit, no claim for arguably-covered damages was made until the EPA
sent the 2008 PRP Letter. It was that letter, according to Land O' Lakes, that required
implementation of the remedy selected in the ROD and provided an estimation of the
cleanup costs that marked the point at which coverage became enforceable. This

                                          -9-
                                           9
argument is unavailing. We agree with the district court that the 2008 PRP Letter was
"simply a continuation of the claims made by the EPA in the 2001 PRP [L]etter."
Emp'rs Mut. Liab., 846 F. Supp. 2d at 1026. The 2008 PRP Letter was not, as Land
O' Lakes urges, the commencement of an entirely new and distinct enforcement action
that initially triggered the Insurers' duty to defend. Rather, it was another step "in a
single, continuous process of EPA enforcement" related to the refinery site. Id. Land
O' Lakes recognized as much at the time.

       In sum, the 2001 PRP Letter put Land O' Lakes on notice that additional
investigation that the Letter mandated might reveal injury to property that would
arguably be covered by the CGL policies that the Insurers issued. It did not matter
that, in 2001, no one knew the full nature and extent of the contamination at the
refinery site. In other words, the EPA's allegations arguably fell within the scope of
coverage provided under the CGL policies and thus triggered the Insurers' duty to
defend. Wooddale Builders, Inc., 722 N.W.2d at 302 (holding that the duty to defend
extends to every claim that arguably falls within the scope of coverage). We agree
with the district court that the Insurers breached their duty to defend in 2001 because
the 2001 PRP Letter was a "suit" for arguably-covered damages as contemplated
under the pertinent CGL policies and that the 2008 PRP Letter was not the
commencement of an entirely new enforcement action. We, therefore, hold that Land
O' Lakes's 2009 duty-to-defend claims were barred by the Minnesota statute of
limitations.5

                         B. Owned-Property Exclusion
     Land O' Lakes next argues that the district court erred in holding that the
owned-property exclusion in the CGL policies relieved the Insurers from any duty to

      5
       Because we affirm the district court's holding that Land O' Lakes's duty-to-
defend claim against Travelers was barred by the statute of limitations, we need not
address Travelers's argument that the district court erred in ruling that Midland was
a "named insured" under the 1965–1970 Travelers policies.

                                         -10-
                                          1
indemnify Land O' Lakes for the cleanup costs. The court based its conclusion on the
fact that the costs to comply with the EPA-mandated cleanup relate solely to
remediation on Land O' Lakes's property and not to remediation on property that
others owned. Although claims that are even arguably covered under a CGL policy
give rise to the duty to defend, only claims that are actually covered under a CGL
policy give rise to the duty to indemnify. See Remodeling Dimensions, Inc. v.
Integrity Mut. Ins. Co., 819 N.W.2d 602, 616–17 (Minn. 2012).

      The CGL policies provide, in general, that the Insurers will pay "on behalf of
[Land O' Lakes] all sums which [Land O' Lakes becomes] legally obligated to pay as
damages because of . . . property damage" to third-party property on account of a
covered occurrence. The Minnesota Supreme Court has interpreted this language to
mean that a causal relationship must exist between the damages for which
indemnification is sought and a covered occurrence that injured third-party property.
SCSC Corp., 536 N.W.2d at 311–12; Minn. Mining and Mfg. Co. v. Travelers Indem.
Co., 457 N.W.2d 175, 182, 184 (Minn. 1990) ("3M") (holding that cleanup costs may
be "damages" under an insurance policy if the damages "are causally related to
covered 'property damage'").

       The CGL policies also provide that the Insurers will not pay for damages to
Land O' Lakes's own property—the so-called owned-property exclusion. Under
Minnesota law, the owned-property exclusion precludes coverage for costs incurred
by an insured to remediate contamination that is "confined to the insured's property
and unrelated to preventing off-site contamination." Domtar Inc. v. Niagra Fire Ins.
Co., 563 N.W.2d 724, 734 (Minn. 1997). If contamination on an insured's own
property has already damaged third-party property, however, government-mandated
"[c]osts and expenses for the cleanup of" the contamination on both the insured's own
property and third-party property may be covered. N. States Power Co. v. Fid. & Cas.
Co. of N.Y., 504 N.W.2d 240, 245 (Minn. Ct. App. 1993), aff'd as modified, 523
N.W.2d 657 (Minn. 1994). But costs and expenses to clean up the insured's own

                                        -11-
                                         1
property in order "to prevent future pollution of a type which has yet to occur or from
a source which has yet to cause pollution . . . are not covered because these costs are
not causally related to the [third-party] property damage." Id. (emphasis added); see
also 3M, 457 N.W.2d at 184 (noting that the costs of "[p]urely preventative measures
are not covered in the absence of property damage"). The Minnesota Supreme Court
held in Domtar that "if there is actual injury and an existing threat to third-party
property (whether private or public), then clean-up on the insured's own property that
is designed to protect third-party property" may be covered despite an owned-
property exclusion. 563 N.W.2d at 734.

       Land O' Lakes first asserts that the district court erred in concluding that it
failed to show that third-party property had been damaged by contamination from the
refinery site—the "actual injury" component of the Domtar test. According to Land
O' Lakes, any contamination of third-party property attributable to the refinery site
is sufficient to satisfy the actual-injury requirement. Because the EPA-ordered
cleanup did not involve any off-site contamination that would satisfy the actual-injury
requirement, Land O' Lakes points to off-site contamination that occurred during
Midland's 1953–1977 operation of the refinery to show the requisite third-party
property damage. According to Land O' Lakes, contaminants released from the
refinery damaged Skull Creek and Cimarron River in the 1970s. These waterways
belonged to third parties and thus satisfied the actual-injury-to-third-party-property
requirement. Land O' Lakes avers, therefore, that all the costs it must now incur to
clean up the refinery site in order to prevent any future damage to any third-party
property fall outside the exclusion—it is irrelevant that the third-party property
actually injured in 1970 is different from the third-party property subject to an
existing threat that the current cleanup is designed to protect against in the future. See
Domtar, 563 N.W.2d at 734.

      The district court provided the following helpful example to illustrate Land O'
Lakes's argument. The owned-property exclusion would deny coverage to a

                                          -12-
                                           1
hypothetical insured who incurs costs to comply with a 2013 order by the EPA to
repair a corroded storage tank that could leak chemicals onto and damage adjoining
third-party Property X at some point in the future. The insured's costs to repair the
tank would not be covered because there had been no prior contamination of the
insured's own property. This is true even if the purpose of the 2013 repair is to protect
third-party Property X from future damage caused by an existing threat. Assuming the
same set of facts, assume further that in 1950, a pipe on the insured's property had
leaked a small amount of oil onto the insured's property that seeped onto adjoining
third-party Property Y. Under Land O' Lakes's theory, the cost of replacing the
chemical-storage tank that threatens Property X in 2013 must now be borne by the
insurer because of an actual injury to third-party Property Y in 1950—even though
the 1950 oil-pipe leak onto Property Y is completely unrelated to the threatened
chemical-storage-tank leak onto Property X in 2013. See Emp'rs Mut. Liab., 846 F.
Supp. 2d at 1032.

       As the district court observed, "[t]his is a facially absurd result" that disregards
the requirement under Minnesota law and the CGL policies that a causal relationship
exist between the cleanup activities and the injury to third-party property. Id.
Moreover, it impermissibly broadens the scope of coverage provided under the CGL
policies. Based on the foregoing, we conclude that Land O' Lakes has failed to
establish an "actual injury" to third-party property.

       Land O' Lakes next argues that the district court erred in holding that it cannot
satisfy Domtar's existing-threat-to-third-party-property requirement with evidence of
"a threat to the general environment." As explained above, Domtar requires both
actual injury to third-party property and an existing threat to the same third-party
property that the current cleanup is designed to protect. Because we have already
concluded that Land O' Lakes has failed to establish an actual injury to third-party
property as required under Domtar, we need not address Land O' Lakes's assertions
of error in the district court's determination that Land O' Lakes failed to show an

existing threat to third-party property. In any event, we agree with the district court
that Land O' Lakes cannot establish an existing threat to third-party property
sufficient to overcome the application of the owned-property exclusion by merely
adducing evidence of a threat to the environment in general.

       Land O' Lakes argues that the district court's ruling cannot be reconciled with
this court's opinion in Continental Insurance Companies v. Northeastern.
Pharmaceutical & Chemical Company, 811 F.2d 1180 (8th Cir. 1987).6 Land O'
Lakes contends that Continental stands for the proposition that because a state or
federal government suffers actual "property damage" when the land, water, or air in
its particular jurisdiction is contaminated, damage to the environment in general is
"property damage" to third-party property. It follows, according to Land O' Lakes,
that "if actual damage to the general environment constitutes 'property damage'" to
third-party property, "then a threat [of damage] to the general environment" must also
constitute a threat of damage to third-party property. Assuming for the sake of
argument that Cont'l Ins. Cos., which applied Missouri law, has any bearing on this
case, Land O' Lakes's interpretation of Cont'l Ins. Cos. overstates the scope of the
decision. In Cont'l Ins. Cos., the court considered whether "the improper release of
toxic wastes may cause property damage not only to the actual owner of the land,
water, or air, but also to state and federal governments because of their interest
independent of and behind the titles of its citizens in all the earth and air within their
domain." Cont'l Ins. Cos., 811 F.2d at 1187 (quotations, alteration, and citation
omitted). Just because a state or the federal government may possess some theoretical

       We note that the panel opinion upon which Land O' Lakes relies was vacated
by our court en banc. See Continental Insurance Companies v. Northeastern
Pharmaceutical & Chemical Company, Inc., et. al., 842 F.2d 977 (1988) (en banc).
Subsequently, the Missouri Supreme Court expressly repudiated a portion of our en
banc court's statement of Missouri law concluding that our decision "misconstrues
and circumvents Missouri law" with respect to defining damages. See Farmland
Indus. v. Republic Ins. Co., 941 S.W. 2d 505, 510 ( Mo. 1997) (en banc).

interest in an insured's property does not mean that the property is not owned by the
insured for purposes of insurance contract interpretation. As the district court noted,
if third-party property under the CGL policies included the "environment" in general,
the owned-property exclusion would be "vitiate[d] . . . because every blade of grass
on every plot of land is both the property of the land's owner and a part of the
'environment.'" Emp'rs Mut. Liab., 846 F. Supp. 2d at 1035. Land O' Lakes cannot
satisfy Domtar's existing-threat-to-third-party-property requirement with evidence of
damage only to the general environment, and the district court did not err in so
holding.

       We agree with the district court's conclusion that Land O' Lakes's costs to
remediate the refinery site fall within the owned-property exclusion because Land O'
Lakes has not established that (1) third-party property had been contaminated by
hazardous materials from the refinery site; (2) that same third-party property remained
contaminated at the time the EPA ordered Land O' Lakes to clean up the refinery site;
(3) the hazardous materials from the refinery site posed a continuing threat of
contamination to that same third-party property; and (4) the EPA-mandated cleanup
of the refinery site was designed to protect that same piece of third-party property
from further contamination by hazardous materials from the refinery site.

                                  III. Conclusion
      For the foregoing reasons, we affirm the judgment of the district court.
