Granting the insured's motion for partial judgment on the pleadings, the court determined the insurers had a duty to defend. Suez Treatment Solutions, Inc. v. Ace Am. Ins. Co. & Liberty Mut. Fire Ins. Co., 2022 U.S. Dist. LEXIS 59044 (S. D. N. Y. March 30, 2022).

Suez Treatment Solutions, Inc. held policies from Chubb and Liberty Mutual Fire Insurance Company to cover its operations in connection with the development of a pollution treatment system in North Carolina. When the project ultimately failed, an underlying action sought damages from Suez, alleging breach of contract, negligence, and fraud. Suez filed this case seeking a declaratory judgment that Chubb and Liberty were each obligated to defend and indemnify Suez in the underlying case.

The City of High Point hired Suez to upgrade the facilities at its wastewater treatment plant staring in 2021. Because mercury levels were too high in emissions from sewage-sludge incinerators, Suez began working on the installation of a Mercury Removal System. After installation, a leak occurred in a component known as the heat exchanger. The leak caused the system to shut down and weeks-long repairs began.
