Appellant, Wrecking Corporation of America, Virginia, Inc. (WCA), appeals from the grant of summary judgment to appellee, Insurance Company of North America (INA), on the ground that the trial judge erred in ruling that INA had no duty to defend WCA since the property damage (the compensable occurrence under the insurance policy) occurred after the policy had been cancelled. Appellant contends that the policy was an occurrence policy and hence covered property damage as a result of alleged negligence during the period the policy was in effect. We affirm. 1
I
In March 1979, WCA, a demolition subcontractor, began doing demolition work at the Papermill Project and completed its work on August 12, 1979. A portion of a wall on which WCA had worked collapsed in October 1979. WCA had obtained a general liability policy from INA covering WCA for property damage (other than caused by blasting) at the site. The policy provided that “property damage” is
physical injury to or destruction of tangible property which occurs during the policy period, including the loss thereof at any time resulting therefrom....
The policy defined “occurrence” to mean
an accident, including continuous or repeated exposure to conditions, which results in bodily injury or property damage neither expected nor intended from the standpoint of the insured.
The policy was in effect from March 1, 1979, until August 27, 1979, when it was cancelled at the request of WCA.
INA also insured the contractor at the Papermill Project for all of the damage caused by the collapse of the wall. Having paid the contractor’s claim, INA sought subrogation against WCA alleging that the collapse of the wall was due solely to WCA’s negligence. WCA notified INA of the claim and requested that INA appoint an attorney to defend it. INA refused because, although it agreed that the insurance policy was in effect while WCA worked at the project, the collapse and the property damage occurred after the insurance policy was cancelled.
WCA filed for a declaratory judgment that INA should have provided a defense for it and cross motions for summary judgment were filed. The judge granted INA’s motion. WCA appealed and the case was remanded to the trial court with instructions to rule on the motion in light of the entire insurance policy. Wrecking Corporation of America, Virginia Inc. v. Insurance Company of America, No. 86-18 (D.C. May 5, 1987) (unpublished order). On remand, the trial judge granted INA’s motion on the ground that the insurance policy limited the insurer’s liability to compensation for property damage occurring during the policy period and the damage that was the subject of the litigation occurred in October 1979 after the policy had been terminated; in other words, the compensa-ble occurrence did not take place when the damage-causing activity was performed but when the resulting damage occurred.
II
On appeal WCA contends that the damage at Papermill Project was caused by a *1350 process set in motion by appellant’s actions, rather than by a single act. There are several problems with this contention.
First, the prevailing rule is that “property damage occurs” at the time the damage is discovered or when it has manifested itself.
See, e.g., Aetna Casualty & Surety Co. v. PPG Industries, Inc.,
Second, a limited exception exists where the damage can be characterized as being “continuous or progressive.”
E.g., California Union Ins. Co. v. Landmark Ins. Co.,
As the trial judge noted, the court has previously held that “there is nothing [in the legal nature of the duty to defend] that requires that the duty to defend be larger than the scope of the policy.”
S. Freedman & Sons v. Hartford Fire Ins. Co.,
Notes
. Our review of the grant of summary judgment motion is de novo.
Holland v. Hannan,
. WCA first contended that the "occurrence” took place when the negligent process began, rather than when the damage occurred, in its memorandum of points and authorities in opposition to its [renewed] motion for summary judgment and its [renewed] cross motion for summary judgment, but never alleged specific facts to support this argument.
. WCA analogizes this .case to
Kissel v. Aetna Casualty & Surety Co.,
WCA also relies on cases where insureds developed diseases which were linked to exposure or accidents that occurred during the policy period but did not manifest until after the policy expired.
E.g., Lac D’Amiante Du Quebec v. American Home Assurance Co.,
