*382 OPINION OF THE COURT
Onсe again we address the applicability of a pollution exclusion endorsement in an insurance policy
(see e.g. Westview Assoc. v Guaranty Natl. Ins. Co.,
I.
Plaintiff, a painting subcontractor, purchased a commercial general liability (CGL) policy from defendant TIG Insurance Company. The policy provides that TIG would defend and indemnify plaintiff for claims of bodily injury and property damage up to one million dollars. The policy contains a standard form “Total Pollution Exclusion Endorsement,” which excludes coverage for “ ‘Bodily injury’ or ‘property damage’ which would not have occurred in whole or part but for the actual, alleged or threatened discharge, dispersal, seepagе, migration, release or escape of pollutants at any time.” “Pollutants” are defined as “any solid, liquid, gaseous or thermal irritant or contaminant including smoke, vapor, soot, fumes, acid, alkalis, chemicals and waste.”
In 1997, Joseph Cinquemani commenced an action аgainst plaintiff and several others, alleging that he was injured as a result of inhaling paint or solvent fumes in an office building where plaintiff insured was performing stripping and painting work. Plaintiff submitted the lawsuit to its insurer, seeking defense and indemnification. TIG responded that it would not cover Cinquemani’s claim, relying on the policy’s pollution exclusion.
Plaintiff then commenced the present action seeking a declaratory judgment that its insurer is obligated to defend *383 and indemnify it in the underlying personal injury action. Supreme Court granted TIG’s motion for summary judgment and denied plaintiffs cross motion, concluding that the underlying claim falls within the unambiguous language of the pollution exclusion. The court rejected plaintiffs contention that the exclusion is inapplicable because the underlying injury was not caused by environmental or industrial pollution, stating “it has been held that indoor аir contamination * * * can constitute environmental pollution.”
The Appellate Division reversed and granted summary judgment to plaintiff. Relying on
Westview Assoc. v Guaranty Natl. Ins. Co.
(
II.
We begin with fundamentals. We read an insurance policy in light of “common speech” and the reasonable expectations of a businessperson (Ace
Wire & Cable Co. v Aetna Cas. & Sur. Co.,
This is not the first time this Court has construed a pollution exclusion in the context of a personal injury claim. Indeed, two of our decisions have particular relevance to the issue now before us.
In
Continental Casualty,
the Court held that the pollution exclusion at issue was ambiguous as applied to the underlying asbestos exposure injuries and therefore found in favor of the
*384
insured.
1
We reasoned that, although asbestos may be an irritant, contaminant оr pollutant under the exclusion, the clause was ambiguous with regard to whether the asbestos fibers that caused the injuries were discharged into the atmosphere as contemplated by the exclusion (
Similarly, in
Westview
we rejected the insurer’s argument that a pollution exclusion negated coverage for claims based on lead paint poisoning, concluding that, among other things, the insurer failed to meet its heavy burden of showing that lead paint is unambiguously included within the exclusion’s definition of “pollutant” (
In the present matter, TIG contends that the endorsement at issue clearly and unambiguously applies to exclude coverage. The insurer argues that, unlike Westview, the injury-causing element here — paint or solvent fumes — is well within the defined pollutants, which specifically include “fumes.” Further, TIG argues that, unlike Continental Casualty, the clause at issue in this case does not include the language “into or upon land, the atmosphere or any water course or body of water.” That omission, the insurer contends, unambiguously renders the exclusion applicable. We disagree.
III.
Since their genesis approximately 30 years ago, pollution exclusion clauses in their various incarnations have engendered litigation, and divergent results.
Pollution exclusions actually originated in insurers’ efforts to avoid potentially open-ended liability for the type of long-term, gradual discharge of hazardous waste and byproducts exemplified by the Times Beach and Love Canal disasters
(see American States Ins. Co. v Koloms,
177 111 2d 473, 490,
In New York, the pollution exclusion was required in all commercial and industrial liability policies from 1971 to 1982 to “assure that corporate polluters bear the full burden of their own actions spoiling the environment” (Governor’s Mem approving L 1971, ch 765-766, 1971 McKinney’s Session Laws of NY, at 2633). When the law was amended to allow insurers to provide coverage for pollution, it was part of a “comprehensive effort to encourage industry responsibly to handle its hazardous wastes” and “safeguard the public from the adverse consequences of hazardous waste handlers which become financially disabled” (Governor’s Mem approving L 1982, ch 855-856, 1982 McKinney’s Session Laws of NY, at 2629).
The first pollution exclusion clause — the “qualified pollution exclusion” — appeared in most CGL policies issued between the early 1970s and 1985. It broadly excluded coverage for damages “arising out of the discharge, dispersal, release or escapе of smoke, vapors, fumes, acids, alkalis, toxic chemicals, liquids or gases, waste material or other irritants, contaminants or pollutants into or upon land, the atmosphere or any water course or body of water.” The exclusion typically provided that it would
not
apрly where the polluting discharge or release is “sudden and accidental.” Courts nationwide split on the interpretation of that clause, most pointedly diverging on the application of the terms “sudden and accidental” to instances of gradual pollution
(compare e.g. Northville Indus. Corp.,
The next generation of pollution exclusions began about 1985, when insurers replaced the qualified pollution exclusion with the “absolute” or “total” pollution exclusion, which contains no exception for sudden and accidental incidents
(see
9 Couсh on Insurance 3d § 127:14; 2 Stempel, Insurance Contract Disputes § 14.11 [a] [2d ed]). While ending the debate surrounding “sudden and accidental,” the absolute or total pol
*386
lution exclusion sparked new controversy.
3
Many courts have pronounced the exclusion unambiguous and applied it broadly, even to incidents that are not classiс environmental pollution
(see e.g. Deni Assoc. of Fla., Inc. v State Farm Fire & Cas. Ins. Co., 711
So 2d 1135 [Fla 1998] [ammonia spill in insured’s office building];
Assicurazioni Generali, S.p.A. v Neil,
Courts following the latter approach have done so for a variety of reasons: because terms such as “dispersal,” “discharge,” “irritant” or “contaminant” are terms of art in environmental law
(see Nautilus Ins. Co.,
The absolute or total pollution exclusions also typically dropped the language “into or upon land, the atmosphere or any water course or body of water.” This has generated yet another controversy: does the deletion of the “land,” “atmosphere” and “water” language make a difference? Some courts have held that the omission expands the scope of the exclusion beyond classic environmental pollution
(see Oates v State of New York,
With this background in mind, we turn to the question whether the clause now before us unambiguously excludes coverage for injuries caused by inhalation of paint or solvent fumes in an office the insured was painting. We conclude that it does not.
IV.
Neither the inclusion of “fumes” in the definition of “pollutant,” nor the absence of the “land,” “atmosphere” or “water” language, persuades us that the exclusion is unambiguous as applied in this case. Reasonable minds can disagree as to whether the exclusion аpplies here.
Although the ambiguity in
Continental Casualty
began with a focus on the term “atmosphere,” we rested our holding additionally on the fact that the terms used in the exclusion to describe the method of pollution — such as “discharge” and “dispersal” — are “terms of art in environmental law used with reference to damage or injury caused by disposal or containment of hazardous waste”
(Continental Cas.,
TIG understandably relies on the policy definition of “pollutants” as “any solid, liquid, gaseous or thermal irritant or contaminant including * * * fumes.” (Emphasis added.) This argument, however, proves too much. Were we to adopt TIG’s interpretation, under the language of this exclusion any “chemical,” or indeed, any “material to be recycled,” that could “irritate” person or property would be a “pollutant.” We are reluctant to adopt an interpretation that would infinitely enlarge the scope of the term “pollutants,” and seemingly contradict both a “common speech” understanding of the relevant terms and the reasonable expectations of a businessperson.
Nor can the word “fumes” be isolated from its context in the endorsement. Even if the paint or solvent fumes are within the definition of “pollutant,” the exclusion applies only if the underlying injury is caused by “discharge, dispersal, seepage, migration, release or escape” of the fumes. It cannot be said
*388
that this language unambiguously appliеs to ordinary paint or solvent fumes that drifted a short distance from the area of the insured’s intended use and allegedly caused inhalation injuries to a bystander
(see Roofers’ Joint Training, Apprentice & Educ. Comm. v General Acc. Ins. Co., 275
AD2d 90 [4th Dept 2000]). As one court noted in a similar factual setting, “it strains the plain meaning, and obvious intent, of the language to suggest that these fumes, as they went from the container to [the injured party’s] lungs, had somehow been ‘discharged, dispersed, released or escaped’ ”
(Meridian Mut. Ins. Co.,
Finally, we reject TIG’s contention that the absence of the language “into or upon land, the atmosphere or any water cоurse or body of water” is a material difference that indicates an intent to extend the exclusion to indoor, as well as outdoor, pollution. Because any pollution will necessarily involve discharge or release into land, atmosphere or water, the omission of such language in the present policy simply removes a redundancy in the exclusion. It does not eliminate or overcome the environmental implications of the terms “discharge, dispersal, seepage, migration, release or escape”
(see Tufco,
104 NC App at 324-325,
Having concluded that the endorsement is ambiguous as applied here, we agree with the Appellate Division that summary judgment should be awarded to plaintiff insured.
Accordingly, the order of the Appellate Division should be affirmed, with costs.
Judges Smith, Ciparick, Rosenblatt, Graffeo and Read concur.
Order affirmed, with costs.
