Appeal from an order of the Supreme Court (Work, J.), entered September 26, 2006 in Ulster County, which, among other things, denied the motion of defendant Harco National Insurance Company for summary judgment declaring that it had no duty to defend or indemnify plaintiff in certain actions commenced against it.
In January 2004, a sewer main ruptured in the City of Kingston, Ulster County, discharging a flood of water and sewage into multiple homes and forcing evacuations. The affected residents (hereinafter collectively referred to as defendants) filed notices of claim and, ultimately, suit against plaintiff seek-
Plaintiff thereafter commenced this declaratory judgment action seeking, among other things, a declaration that Harco was required to defend and indemnify it for any resulting liability to defendants. Following joinder of issue and discovery, Harco moved for summary judgment and plaintiff cross-moved for similar relief. Supreme Court denied Harco’s motion in its entirety and partially granted plaintiffs motion, declaring that Harco was required to provide plaintiff with a defense in the underlying actions. This appeal by Harco ensued.
We affirm. Preliminarily, we reject Harco’s assertion that the fungi or bacterial exclusion contained in the policy provides an alternate basis for denying coverage. The case law makes abundantly clear that “an insurer’s disclaimer is strictly limited to those grounds stated in the notice of disclaimer, which disclaimer must clearly apprise the insured of the grounds on which the disclaimer is based” (Maroney v New York Cent. Mut. Fire Ins. Co., 10 AD3d 778, 780-781 [2004], affd 5 NY3d 467 [2005] [internal quotation marks and citation omitted]; see Kokonis v Hanover Ins. Co., 279 AD2d 868, 870 [2001]). Having failed to invoke the fungi or bacterial exclusion in the April 2004 disclaimer letter, Harco cannot now be heard to complain.
Turning to the issue of Harco’s duty to defend, it is well settled that “an insurer’s duty to defend its insured arises whenever the allegations in a complaint state a cause of action that gives rise to the reasonable possibility of recovery under the policy” (Fitzpatrick v American Honda Motor Co., 78 NY2d 61, 65 [1991]). Stated another way, “[i]f any of the claims against [an] insured arguably arise from covered events, the insurer is required to defend the entire action” (Town of Massena v
Assuming, without deciding, that raw sewage unambiguously constitutes a “contaminant” and, hence, falls within the scope of the policy exclusion invoked here, Harco nonetheless failed to demonstrate that the underlying complaints cast those pleadings wholly within that exclusion and, further, that there is no possible factual or legal basis upon which it ultimately could be obligated to indemnify plaintiff. A review of the relevant complaints, as well as the examination before trial testimony of certain defendants (see Durant v North Country Adirondack Coop. Ins. Co., 24 AD3d 1165, 1166 [2005] [“extrinsic evidence may be used to expand the insurer’s duty to defend”]), makes clear that at least some of the damages incurred by defendants arguably is attributable to the force of the rushing of water, variously described as a “flood” or “river” flowing like “Niagara Falls,” that passed through and over defendants’ respective properties. Contrary to Harco’s assertion, it cannot be said that the erosion and structural damage alleged in the form of shifted foundations and cracked interior walls would not have occurred “but for” the presence of raw sewage. Accordingly, we agree with Supreme Court that Harco plainly has a duty to defend plaintiff in the underlying actions and, further, that the issue of its duty to indemnify must await the proof at trial.
Cardona, P.J., Mercure, Carpinello and Lahtinen, JJ., concur. Ordered that the order is affirmed, without costs.
