TOLEDO, Ohio — Five companies have agreed to pay the federal government more than $7.2 million overall to resolve claims stemming from longstanding pollution in two adjacent creeks in the Maumee River watershed in northwestern Ohio.

The settlement with Ohio Refining Co., Chevron USA, Energy Transfer LLC, Pilkington North America and Chemtrade Logistics was announced Monday by the U.S. Department of Justice. Officials said a federal judge must approve the deal before it takes effect.

According to a complaint, the companies are liable for historic industrial discharges of oil or hazardous substances at the Duck & Otter Creeks site near Toledo. The site is just east of the Maumee River and encompasses the creeks, adjoining wetlands, floodplain areas and uplands.

The two creeks flow into Maumee Bay in Lake Erie and provide key habitats for migratory birds and fish, and also support hunting and fishing activities for local residents, according to federal wildlife officials.
