Opinion

CARTER, Justice.

Interstate Power Company (Interstate), the plaintiff in this declaratory judgment *753 action, appeals from a summary judgment in favor of the defendant Insurance Company of North America (INA) with respect to Interstate’s allegations that INA insured it against liability for environmental cleanup costs at several locations. After reviewing the record and considering the arguments presented, we affirm the judgment in part, reverse it in part, and remand the case to the district court for further proceedings.

The environmental damage that precipitated the present litigation occurred at nine sites owned or formerly owned by Interstate. Manufactured gas had been produced on these sites by Interstate, its predecessors in interest, or third parties. These sites are located in Clinton, Iowa; Mason City, Iowa; Galena, Illinois; Savanna, Illinois; Albert Lea, Minnesota; Austin, Minnesota; New Ulm, Minnesota; Owatonna, Minnesota; and Rochester, Minnesota. A chronology of the operations at these locations is listed below:

During the period from May 1, 1946, until May 1, 1964, INA provided general comprehensive liability insurance to Interstate. Interstate is claiming under the provisions of that insurance coverage relating to “property damage.” It urges that such coverage extends to'the liability imposed upon it by state and federal agencies for environmental cleanup costs at the sites that we have described.

■ During the years from May 1, 1946, to May 1, 1961, the INA policy provided that liability for property damage extended to “damages because of injury to or destruction of property including the loss of use thereof, caused by accident.” In contrast, personal injury coverage under the policy during this period was provided on an “occurrence” basis. Interstate concedes that, in order for INA’s liability policy to be triggered for the 1946-1961 period, it must establish that the environmental contamination that it is required to remediate was the result of accident.

In ruling on INA’s summary judgment motion, the district court concluded that it was undisputed in the motion papers that the contamination at issue occurred as a result of coal tar, coke, and other residues from the manufacturing process being allowed to accumulate on the unprotected earth, and thereafter be dissolved by rain, melting snow, or other sources of moisture. This process occurred over a period of decades. The court concluded from these circumstances that the environmental damages at issue here were the result of natural causes rather than being accidental. Although evidence was presented that some fuel spills may have occasionally occurred on these properties, Interstate no longer asserts that such spilling, accidental or otherwise, constitutes an accident or accidents triggering liability coverage under the INA policy. Rather, Interstate contends that the exposure of the coal tar, coke, and other residual solids from the manufacturing operations to natural precipitation is the defining event that constitutes an “accident” for purposes of INA’s policy. Other facts which bear upon our decision will be considered in our discussion of the legal issues presented.

I. Whether the Alleged Property Damage was Caused by Accident.

In seeking to overturn the ruling of the district court on the policies in effect *754 for the years 1946 to 1961, Interstate asserts that the district court improperly focused on whether there had been a causative event during the policy period that qualified as an accident. It argues that based on the language of the policy any accidental property damage during the policy period triggered coverage regardless of when and how the subsequent contamination took place. This assertion is designed to controvert temporal considerations contained in the district court’s ruling. We believe, however, that it is not necessary to decide the motion for summary judgment based on temporal considerations. What happened here simply does not constitute an accident at any point in time.

The controlling consideration in interpreting insurance policies is the intent of the parties. Iowa Comprehensive Petroleum Underground Storage Tank Fund Bd. v. Farmland Mut. Ins. Co., 568 N.W.2d 815, 818 (Iowa 1997); Pierce v. Farm Bureau Mut. Ins. Co., 548 N.W.2d 551, 555 (Iowa 1996). We ordinarily determine that intent from the language of the policy itself unless the policy is ambiguous. Farmland Mut., 568 N.W.2d at 818; Kibbee v. State Farm Fire & Cas. Co., 525 N.W.2d 866, 868 (Iowa 1994). When a policy term is not defined in the policy as in this case, we give the term its ordinary meaning. Pierce, 548 N.W.2d at 555.

The critical policy language in the present case provides:

I. Coverage.
The company hereby agrees to indemnify the insured [against]....

(b) Property Damage Liability.
For damages because of injury to or destruction of property, including the loss thereof, caused by accident.
