Case Summary

This case involves a dispute between Sterigenics U.S., LLC and its insurer, National Union Fire Insurance Company of Pittsburg, over insurance coverage for environmental liabilities. Sterigenics sought coverage for costs related to environmental contamination at its facilities. The core issue revolved around whether certain costs, specifically those incurred for investigating and remediating pollution, were covered under the 'property damage' provisions of the insurance policies. The district court initially ruled in favor of the insurer, finding that Sterigenics' claims were not covered. The Seventh Circuit Court of Appeals reviewed the district court's decision. The appellate court focused on the interpretation of the insurance policies, particularly the definition of 'property damage' and the application of pollution exclusions. The court ultimately affirmed the district court's judgment, concluding that the costs Sterigenics sought to recover did not fall within the scope of 'property damage' as defined by the policies, nor were they covered due to the specific exclusions for pollution-related incidents. Therefore, Sterigenics was not entitled to coverage from National Union for these environmental liabilities.
