claimed for a declaration that Western World was obligated to indemnify it. The district court held that a “Total Pollution Exclusion” endorsement to the policy totally excluded coverage for Stack’s clean-up expenses and related costs. We agree with the district court and affirm the judgment.
BACKGROUND
Stack sells fuel oil. On September 26, 1985, Western World issued to Stack a Manufacturer’s and Contractor’s Liability Insurance Policy (the “policy”). The policy was effective for one year from September 26, 1985. One month later, on October 22, 1985, vandals entered Stack’s property and opened a storage tank valve, causing approximately 70,000-80,000 gallons of fuel oil to flow into nearby waterways. Stack incurred massive clean-up costs, and demanded that Western World cover approximately $240,000 of these expenditures. In the belief that the act of vandalism was “sudden and accidental,” Stack based its demand upon the following clause in the policy:
This insurance does not apply ... to 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 and accidental.
(emphasis added).
Western World denied coverage, citing an endorsement to the policy entitled “Total Pollution Exclusion.” The endorsement, dated the same day as the oil spill, October 22, 1985, but effective retroactive to September 26, 1985, provides:
This insurance does not apply to bodily injury, personal injury, or property damage arising out of pollution or contamination caused by the discharge or escape of any pollutants or contaminants.
Thus, the endorsement, if effective, excludes all pollution damage, whether accidental or otherwise.
Stack disclaims all knowledge of the Total Pollution Exclusion endorsement and argues that it is simply not part of the policy. Accordingly, the facts surrounding the procurement of the policy with Western World are crucial.
Stack had previously placed its insurance with Security Insurance Company (“Security”), but its policy with Security had been cancelled effective August 20, 1985. Stack then directed William Guerrera, its insurance agent, to get the same coverage with some other company as soon as possible.
Guerrera contacted Continental Insurance Agency of Connecticut (“Continental”), which had authority to bind coverage on behalf of Western World, to discuss Western World’s willingness to issue Stack the required insurance. Denise Borrelli, a Continental employee, discussed with Guerrera the terms of Western World’s policy, including the fact that the policy did not afford coverage for pollution. Guerr-era admitted at his deposition that he informed a principal at Stack that Western World’s policy “contained no pollution [coverage].”
Anxious to remedy its uninsured status but unable to obtain insurance elsewhere, Stack authorized Guerrera to secure the policy from Western World. On or about September 26, 1985, Guerrera contacted Continental and agreed to take the coverage provided by Western World. Guerrera was admittedly not an agent of Western World, yet for reasons not entirely clear from the record, Guerrera issued to Stack a certificate of insurance, which did not contain the Total Pollution Exclusion endorsement. When Continental learned this, it reissued the certificate of insurance containing the Total Pollution Exclusion endorsement. As fate would have it, the endorsement was dated the very day of the oil spill.
Western World commenced this action for declaratory relief to determine its liability under the policy. The district court granted Western World’s motion for sum
