APPEAL
from an order of the circuit court for Waukesha County: ROBERT G. MAWDSLEY, Judge. Affirmed.
Before
Anderson, P.J., Nettesheim and Snyder, JJ.
NETTESHEIM,
J. Urban Land Interests, Inc., (ULI) appeals
from the trial court’s grant of summary judgment to its insurer, The Hanover
Insurance Company. The trial court
ruled that the pollution exclusion clauses in the Hanover policies barred
coverage to ULI. Specifically, the
court ruled that exhaled carbon dioxide is a “pollutant” which was “discharged, dispersed or
released” within the meaning of the pollution exclusion clauses. We agree with the court's construction of
the policies. We therefore affirm the
grant of summary judgment to Hanover.
BACKGROUND
The
factual background of the case is not in dispute. Both Sandy Donaldson and April Schmitt worked in the clerical
room of the Barstow building managed by ULI.
During the course of their employment, Donaldson and Schmitt began to
suffer from a number of symptoms, most of which would occur shortly after
arriving at work and resolve within two hours of leaving work. Donaldson complained of headaches, sinus
infections, eye irritation, extreme fatigue, upset stomachs, sinus drainage and
asthma. Schmitt suffered from a sore
throat, nausea, ear pounding, sinus pain and congestion.
As
a result, both Donaldson and Schmitt sought medical treatment from Dr. Jordan
Fink of the Medical College of Wisconsin.
Fink concluded that both Schmitt and Donaldson had symptoms which were
“consistent with a diagnosis of ‘sick building syndrome.’” In a letter to a worker’s compensation
claims examiner regarding Donaldson, Fink stated:
I believe that many of Ms. Donaldson’s reported symptoms
were causally related to exposures of excessive concentrations of air
contaminants in the basement of the Barstow Building. While specific irritants and air concentrations were not
determined, the accumulation of excessive concentrations of carbon dioxide
provide sufficient factual foundation to conclude that the ventilation was
inadequate and, as a result, a variety of other air contaminants likely
accumulated as well.
Fink's
diagnosis was based in part upon an industrial hygiene survey conducted by the
Safety and Buildings Division of DILHR in response to employee concerns about
the quality of air in the Barstow building.
The results of the survey indicated that while certain areas of the
Barstow building met or exceeded air exchange standards, other areas had little
or no ventilation. The survey stated in
relevant part that there “was not the required air circulation of 6 air changes
per hour. The clerical area (Room 100)
did not have any circulation.” Fink
therefore recommended that Donaldson and Schmitt avoid exposure to the clerical
area until the ventilation system in the building had been repaired.
In
July 1994, Donaldson and Schmitt brought the instant action against ULI and
Hanover. Their complaint alleged
injuries caused by the “poor air quality” in the Barstow building.[1] Hanover denied its duty to defend claiming
that its policy did not afford coverage.
Hanover brought a motion for summary judgment to resolve this
issue. Specifically, Hanover relied on
the pollution exclusion provision recited in both the comprehensive general
liability policy and the umbrella excess liability policy issued to ULI. Hanover claimed that these provisions
precluded coverage for bodily injury arising from airborne contaminants. ULI filed a cross-motion for summary
judgment on the same issue, requesting the court to find that the exclusion
clauses did not bar coverage and to require Hanover to defend on the
plaintiffs' claims.
The
trial court granted Hanover’s motion for summary judgment. The court also denied ULI’s reconsideration
motion and confirmed the grant of summary judgment to Hanover. ULI appeals.
DISCUSSION
The
Insurance Policy
The
Hanover policies each contain an “absolute”[2]
pollution exclusion clause which excludes coverage for:
(1) “bodily injury” or “property damage” arising
out of the actual, alleged or threatened discharge, dispersal, seepage,
migration, release or escape of pollutants:
(a) At or from any premises, site, or location
which is or was at any time owned or occupied by, or rented or loaned to, any
insured
(2) ¼ Pollutants means any
solid, liquid, gaseous or thermal irritant or contaminant, including smoke,
vapor, soot, fumes, acids, alkalis, chemicals and waste. Waste includes materials to be recycled,
reconditioned or reclaimed.
The
trial court held that the exhaled carbon dioxide was a “gaseous irritant” which
constituted a pollutant, and that the expelled accumulation of carbon dioxide
qualified as a “discharge, dispersal, seepage, migration, release or escape of
pollutants”[3]
within the meaning of the policy. Thus,
the court granted summary judgment to Hanover.
We
review summary judgment de novo, using the same standards and methodology
applied by the trial court. Voss
v. City of Middleton, 162 Wis.2d 737, 748, 470 N.W.2d 625, 629
(1991). The court must grant summary
judgment if the pleadings, depositions, answers, admissions and affidavits show
that there is no genuine issue of material fact and, as a matter of law, the
moving party is entitled to judgment. Id.
Whether
the pollution exclusion clause of the Hanover policy is applicable to the
situation at bar breaks down into two inquiries: 1) is exhaled carbon dioxide a pollutant under the terms of the
policy; and, if so (2) was the exhaled carbon dioxide discharged, dispersed,
etc., within the meaning of the policy?
Both inquiries must be answered in the positive for the pollution
exclusion clause to apply.
Two
court of appeals decisions involving pollution exclusion clauses are relevant
to our discussion. In United
States Fire Ins. Co. v. Ace Baking Co., 164 Wis.2d 499, 476 N.W.2d 280
(Ct. App. 1991), the court concluded that the exclusion clause barred
coverage. In Leverence v. United
States Fidelity & Guar., 158 Wis.2d 64, 462 N.W.2d 218 (Ct. App.
1990), the court concluded that the exclusion clause did not bar coverage. Despite the opposite conclusions, we
conclude that the cases are not in conflict and that they support Hanover's
argument for no coverage.
Pollutant
We
first consider whether exhaled carbon dioxide is a “pollutant” within the
meaning of the exclusion clause.
In
Ace Baking, ice cream cones manufactured by Ace Baking were
stored in the same warehouse as the fabric softener Bounce. Ace Baking, 164 Wis.2d at 501,
476 N.W.2d at 281. Following a
complaint by one of its customers, an investigation revealed that the fragrance
additive, linalool, from the fabric softener caused the ice cream cones to
become unusable. Id. Ace Baking presented a claim to its insurer
for damage to its cones. The insurer
refused coverage under the policy’s pollution exclusion clause. Id.
Similar
to the Hanover policy, the pollution exclusion clause in Ace Baking
barred recovery for losses “caused by or resulting from ¼ release, discharge
or dispersal of ‘pollutants.’” Id.
at 502, 476 N.W.2d at 281. However,
unlike the Hanover policy, the Ace Baking policy did not define
the term “pollutant.” Id.
at 502, 476 N.W.2d at 281-82. Thus, the
decision in Ace Baking focused on the meaning to be given to that
term.
The
trial court in Ace Baking had concluded that the term “pollutant”
should be given a narrow meaning: “The
ordinary person would interpret pollutant as something that would adversely
affect the environment or a person’s health.”
Id. at 502, 476 N.W.2d at 282. Under this definition, the trial court concluded that linalool
was not such a pollutant as indicated by the affidavits but could and
apparently did affect a product’s taste or smell. See id.
The court of appeals disagreed.
The court held that if the substance which contaminated the ice cream
cones was “foreign” to the cones, the substance qualified as a pollutant. Id. at 505, 476 N.W.2d at
283. The court noted:
it is
a rare substance indeed that is always a pollutant; the most noxious of
materials have their appropriate and non-polluting uses. ¼ Here, although linalool is a valued
ingredient for some uses, it fouled Ace Baking’s products. Accordingly, it was a “pollutant” in
relation to those products, and coverage for the resulting damages is excluded
from the United States Fire policy.
Id.
In
the instant case, we need not search for a definition for “pollutant,” since
the Hanover policy defines it as “any solid, liquid, gaseous or thermal
irritant or contaminant, including smoke, vapor, soot, fumes, acids, alkalis,
chemicals and waste.” The summary
judgment record, as well as common knowledge, demonstrates that carbon dioxide
is a gaseous substance which, at certain levels, can become an irritant or
contaminant.[4]
ULI
argues, however, that the pollution exclusion clause should not apply to carbon
dioxide, a naturally created substance which, absent concentrated levels, is
harmless. However, as Ace Baking
notes, “it is a rare substance indeed that is always a pollutant.” Id. Carbon dioxide is such a substance. In its ordinary state, it is a harmless substance. But in concentrated levels, it can become
injurious, even lethal. At those
levels, it is “foreign” to a safe human environment. See id.
We
affirm the trial court's ruling that the exhaled carbon dioxide was a pollutant
within the meaning of the Hanover policy.
Discharge of
Pollutants
Having
held that the carbon dioxide constituted a pollutant, we next address whether
the carbon dioxide was discharged within the meaning of the exclusion clause.
In
Leverence, the occupants of prefabricated homes manufactured by
Tri-State Homes alleged that their homes retained excessive moisture within the
exterior walls. Leverence,
158 Wis.2d at 72, 462 N.W.2d at 222.
The retained moisture promoted the growth of mold, mildew, fungus,
spores and other toxins which posed a continuing health risk and adversely
affected the value of the units. Id. The occupants sought damages against
Tri-State and its insurer for their bodily injuries and costs of repairs. Id. Tri-State’s insurer denied coverage relying on the policies’
pollution exclusion clauses. Id.
at 96, 462 N.W.2d at 232. The pollution
exclusion clause precluded coverage for:
bodily
injury or property damage arising out of the discharge, dispersal, release or
escape of smoke, vapors, soot, fumes, acids, alkalis, toxic chemicals, liquids
or gases, waste materials or other irritants, contaminants or pollutants into
or upon land, the atmosphere or any water course or body of water; but this
exclusion does not apply if such discharge, dispersal, release or escape is
sudden or accidental.
Id.
The
Leverence court held that the exclusion clause did not bar
coverage because the growth of the microorganisms was the result of water vapor
trapped in the walls. Id.
at 97, 462 N.W.2d at 232. As such, the
court concluded that the contaminants were not released within the meaning of
the policy, “but rather formed over time as a result of environmental
conditions.” Id.[5]
ULI
argues that the same situation exists here.
We disagree. In this case, the
exhaled carbon dioxide was not converted from one substance to another; nor was
it formed over time; nor was it trapped in some unknown confined area. To the contrary, the carbon dioxide was in
its potentially harmful state immediately upon being expelled directly into
atmosphere of the work environment by the human act of breathing.
We
affirm the trial court's ruling that the pollutant was discharged within the
meaning of the exclusion clause.
Environmental vs.
Nonenvironmental Damage
ULI
also argues that the insurance industry intends pollution exclusion clauses to
apply only in situations of environmental injury or damage to soil, air or
water—not to nonenvironmental injury situations such as the instant case. ULI presents insurance industry history to
support this argument. However, our
first and principal focus is on the language of the insurance policy
itself. As our previous discussion
reveals, we construe the exclusion clause to cover the facts of this case.
Moreover,
Ace Baking already demonstrates a scenario in which a pollution
exclusion clause governed a nonenvironmental damage situation. The same is suggested by Leverence
where, were it not for the absence of a discharge or release of the
contaminant, the exclusion clause would have applied to bar coverage in a
nonenvironmental injury setting.
CONCLUSION
We
conclude that the pollution exclusion clause precludes coverage to ULI for the
claims of the plaintiffs in this case.
We affirm the trial court's grant of summary judgment to Hanover.
By
the Court.—Order affirmed.
No. 95-3015(D)
ANDERSON,
J. (dissenting). I respectfully dissent
from the majority’s conclusions that concentrated levels of carbon dioxide are
a pollutant and that carbon dioxide was discharged within the meaning of the
insurance contract’s exclusion clause.
The majority’s opinion unnecessarily broadens the coverage of the
pollution exclusion clause.
Recently,
we held that one form of a pollution exclusion clause was ambiguous because
there were two reasonable interpretations of the clause.[6] In Beahm v. Pautsch, 180
Wis.2d 574, 584, 510 N.W.2d 702, 706 (Ct. App. 1993), we held that the clause
could be read to exclude coverage for liability that accrues from the discharge
of smoke into the atmosphere or it could be read to exclude coverage for
liability where the discharged substance caused harm because of its toxic
nature. In adopting a limiting
interpretation of the pollution exclusion clause, we noted that “[n]owhere in
its history is there any suggestion that the pollution exclusion clause was
intended to exclude more than coverage for liability for environmental
damages.” Id.[7]
I
am convinced that the language in the pollution exclusion clause under analysis
in this case is also ambiguous. There
are at least two interpretations of the clause. First, it can be interpreted as the majority interprets it, to exclude
coverage for damages arising from an accumulation of carbon dioxide due to
inadequate building ventilation; or, second, it can be read to limit coverage
to liability for industrial environmental damages as that is understood by a
reasonable person.
When
confronted with an ambiguous exclusionary clause, the rule of construction is
that the clause is to be strictly construed against the insurer and must also
be interpreted to mean what a reasonable person in the position of the insured
would have understood the words of the contract to mean. Tara N. v. Economy Fire & Casualty
Ins. Co., 197 Wis.2d 77, 90-91, 540 N.W.2d 26, 32 (Ct. App. 1995). I conclude that a reasonable person would
narrowly interpret the pollution exclusion clause to situations involving
environmental catastrophes related to industrial pollution. This interpretation is consistent with the
principle that we narrowly construe exclusionary clauses, rather than broaden
them to include the concentration of “foreign” substances due to poor building
ventilation. A reasonable person would
expect the clause to avoid liability for the spillage of petroleum products in
a creek, but would not expect it to include the avoidance of liability for the
accumulation of carbon dioxide in an office because provisions were not made
for introducing fresh air into the office.
The
majority relies upon United States Fire Ins. Co. v. Ace Baking Co.,
164 Wis.2d 499, 476 N.W.2d 280 (Ct. App. 1991), for the proposition that the
term “pollutant,” as used in the absolute pollution exclusion clause, is not
ambiguous because it is not “reasonably or fairly susceptible to more than one
construction.” Id. at
503-05, 476 N.W.2d at 282-83. In Ace
Baking, it was concluded that a “pollutant” can be any substance,
foreign to another substance, that makes it physically impure or unclean. Id. at 505, 476 N.W.2d at
283. Using this language, the majority
concludes that in concentrated levels carbon dioxide “can become injurious,
even lethal. At those levels, it is ‘foreign’
to a safe human environment.” Majority
op. at 9.
The
majority's conclusion is imprecise because it does not identify at what level
concentrations of carbon dioxide qualify as a foreign substance. It also fails to specify how much exposure,
at that level, is required before the carbon dioxide becomes injurious to human
health. For example, OSHA has
established a limit of exposure of 5000 ppm for an eight-hour shift. See Occupational Safety and Health
Standards, Subpart Z--Toxic And Hazardous Substances, 29 C.F.R.
§ 1910.1000 (1996).
My
principal disagreement with the majority is the conclusion that this case is
different from Leverence v. United States Fidelity & Guar.,
158 Wis.2d 64, 462 N.W.2d 218 (Ct. App. 1990).
The majority distinguishes Leverence as follows:
In
this case, the exhaled carbon dioxide was not converted from one substance to
another; nor was it formed over time; nor was it trapped in some unknown
confined area. To the contrary, the
carbon dioxide was in its potentially harmful state immediately upon being
expelled directly into the atmosphere of the work environment by the human act
of breathing.
Majority op. at 11.
This conclusion that carbon dioxide is potentially harmful as soon as it
is expelled is inconsistent with the majority’s earlier conclusion that “[i]n
its ordinary state [carbon dioxide] ¼ is a harmless substance. But in concentrated levels, it can become injurious, even
lethal. At those levels, it is
‘foreign’ to a safe human environment.”
Majority op. at 9.
The
differences between Leverence and this case are
insignificant. In Leverence,
the allegation was that the construction methods and materials allowed water
vapor to accumulate in the walls. Id.,
158 Wis.2d at 72, 462 N.W.2d at 222. In
this case, the allegation is that improper construction—the failure to provide
outside air intake—caused the accumulation of carbon dioxide. In Leverence, no contaminants
were released but rather they formed over time because of environmental
conditions. Id. at 97,
462 N.W.2d at 232. In this case, the
concentrations of carbon dioxide formed over time due to environmental
conditions created by the failure to introduce fresh air into the building. The only difference in Leverence
and this case is that in Leverence it was microorganisms that
were promoted by the presence of accumulated water vapor that did the damage, id.
at 72, 97, 462 N.W.2d at 222, 232; and here, it is the level of carbon dioxide
that allegedly caused the damage. Because
the operative facts are parallel between Leverence and this case,
I would conclude that the pollution exclusion clause does not apply.
I
also believe the pollution exclusion clause is inapplicable because the
presence of carbon dioxide was not the result of “actual, alleged or threatened
discharge, dispersal, seepage, migration, release or escape of
pollutants.” First, the involuntary human
act of exhaling waste products from the act of breathing cannot reasonably be
made to fit within the insurance policy’s alternatives of how a pollutant
becomes present in the environment.
Second, the insurance policy language indicates that the pollutant’s
presence must result from some form of action; in this case, the presence of
carbon dioxide is the result of inaction—failing to provide fresh outside air
to the office.
The
Seventh Circuit has had the occasion to discuss a pollution exclusion clause
similar to the one in this case. I find
that court’s discussion to be persuasive.
Without
some limiting principle, the pollution exclusion clause would extend far beyond
its intended scope, and lead to some absurd results. To take but two simple
examples, reading the clause broadly would bar coverage for bodily injuries
suffered by one who slips and falls on the spilled contents of a bottle of
Drano, and for bodily injury caused by an allergic reaction to chlorine in a
public pool. Although Drano and chlorine
are both irritants or contaminants that cause, under certain conditions, bodily
injury or property damage, one would not ordinarily characterize these events
as pollution.
To
redress this problem, courts have taken a common sense approach when
determining the scope of pollution exclusion clauses. Westchester Fire Ins. Co. v. City of Pittsburg, 768
F.Supp. 1463 (D. Kan. 1991), aff'd, 987 F.2d 1516 (10th Cir. 1993), for
instance, held that the clause did not bar coverage for injuries arising from
an individual's ingestion of malathion during a municipal pesticide‑spraying
operation. Id. at 1468‑71. Similarly, A‑1 Sandblasting
& Steamcleaning Co. v. Baiden, 53 Or.App. 890, 632 P.2d 1377, 1379‑80
(1981), aff'd, 293 Or. 17, 643 P.2d 1260 (1982), held that coverage was
not barred for paint damage to vehicles which occurred during the spraypainting
of a bridge. See also Atlantic
Mut. Ins. Co. v. McFadden, No. 90‑5487, slip op. (Mass.Super.Ct.
May 28, 1991) (clause does not bar recovery for apartment‑dweller's
ingestion of lead paint) aff'd, 595 N.E.2d 762 (Mass. 1992); Cole v. Celotex Corp., No. 87‑
6170 (La.Dist. Feb. 15, 1990) (recovery not barred for release of asbestos
particles during installation, handling and removal of insulation). The bond that links these cases is plain. All involve injuries resulting from everyday
activities gone slightly, but not surprisingly, awry. There is nothing that unusual about paint peeling off of a wall,
asbestos particles escaping during the installation or removal of insulation,
or paint drifting off the mark during a spraypainting job. A reasonable policyholder, these courts
apparently believed, would not characterize such routine incidents as
pollution.
Pipefitters Welfare Educ. Fund v. Westchester Fire Ins.
Co., 976 F.2d 1037,
1043-44 (7th Cir. 1993).
I
dissent because I believe the majority opinion broadens the scope of the
pollution exclusion clause bringing within its exclusion many incidents that
are not, historically, industrial pollution.
The accumulation of carbon dioxide in a building and the resulting
injuries are the result of the everyday activity of exhaling gone slightly awry
because the building owner failed to ventilate the building. Under such circumstances the pollution
exclusion clause should not apply.
[2] As ULI explains in its brief:
The exclusion clause ¼ is called ‘absolute’ to distinguish it from the ‘sudden and accidental’ pollution exclusion clause which was the industry standard until 1985. Both clauses exclude coverage for injuries caused by the ‘discharge, dispersal, seepage, migration, release or escape of pollutants.’ The ‘sudden and accidental’ clause, however, does not exclude such injuries if the release was ‘sudden and accidental.’ Compare the ‘absolute’ exclusion in this case ... with the ‘sudden and accidental' exclusion discussed in Just v. Land Reclamation Ltd., 155 Wis.2d 737, 456 N.W.2d 570 (1990).
[4] Fink, the treating physician for two of the plaintiffs, used the term “contaminants” throughout his reports regarding the plaintiffs' conditions. Fink concluded that “the accumulation of excessive concentrations of carbon dioxide provide sufficient factual foundation to conclude that the ventilation was inadequate and, as a result a variety of other air contaminants likely accumulated as well.” (Emphasis added.)
[5] In addition, the court held that the pollution exclusion clause was inapplicable despite the coverage preclusion for discharge, dispersal, release or escape which was “sudden and accidental.” Citing the Wisconsin Supreme Court's definition of “sudden and accidental” to mean “unexpected and unintended,” Just, 155 Wis.2d at 746, 456 N.W.2d at 573, the court found that the growth of the molds, fungus and mildew were unexpected and unintended and, therefore, found, in addition, that the exclusion was inapplicable based on the Just decision. Leverence v. United States Fidelity & Guar., 158 Wis.2d 64, 97, 462 N.W.2d 218, 232 (Ct. App. 1990). This determination, however, was secondary to the court's holding that the exclusion was inapplicable because the contaminants had not been released.
[6] The clause under scrutiny in Beahm v.
Pautsch, 180 Wis.2d 574, 580, 510 N.W.2d 702, 705 (Ct. App. 1993),
provided in part:
This policy does not apply to liability
which results directly or indirectly from:
the discharge, dispersal, release or escape of smoke, soot, fumes, acids, alkalis, toxic chemicals, liquids or gases, waste materials or other irritants, contaminants or pollutants into or upon the land, the atmosphere or a water course, body of water, bog, marsh, swamp or wetland.
[7] In Motorists Mut. Ins. Co. v. RSJ, Inc., 926 S.W.2d 679, 681 (Ky. Ct. App. 1996), the Kentucky court commented that “[t]he drafters’ utilization of environmental law terms of art (‘discharge,’ ‘dispersal,’ ‘seepage,’ ‘migration,’ ‘release,’ or ‘escape’ of pollutants) reflects the exclusion's historical objective—avoidance of liability for environmental catastrophes related to intentional industrial pollution.”
