Duty to defend suit by EPA seeking remediation

The EPA and its state equivalent sued the owner of the “Big Cajun II,” a coal power plant in Louisiana, seeking penalties, injunctive relief, and remediation of alleged environmental damage.  Louisiana Generating LLC v. Illinois Union Ins. Co., No. 12-30651 (May 15, 2013).  Applying New York law, the Fifth Circuit found that “Claims, remediation costs, and associated legal defense expenses . . . as a result of a pollution condition” potentially encompassed some of the relief sought by the EPA for past environmental problems.  The Court also found that an exclusion for “[p]ayment of criminal fines, criminal penalties, punitive, exemplary or injunctive relief” did not unambiguously exclude coverage for remediation required by an injunction order, reasoning that such a broad reading “would potentially swallow” the coverage for remediation costs.  Having found a duty to defend, the Court did not reach a question about whether New York law allowed indemnification for civil penalties imposed under the Clean Air Act.
