ExxonMobil has promised to upgrade pollution controls at eight of its manufacturing facilities along the U.S. Gulf Coast under an agreement it reached with federal authorities.

The petrochemical giant will spend about $300 million to install pollution controls at the plants to settle allegations that it violated U.S. environmental law by failing to properly monitor industrial flares at its petrochemical plants, resulting in illegal air pollution.

The U.S. Justice Department, in a statement, said the Exxon facilities — located in Louisiana and Texas — will operate new air pollution control and monitoring technology to reduce the harmful emissions.

“Once fully implemented, the pollution controls required by the settlement are estimated to reduce harmful air emissions of volatile organic compounds (VOCs) by more than 7,000 tons per year,” the DOJ said in a statement. “The settlement is also expected to reduce toxic air pollutants, including benzene, by more than 1,500 tons per year.”

The Justice Department describes VOCs as key components in the formation of smog, which can irritate lungs and inflame respiratory issues like asthma. Chronic exposure can lead to leukemia and adverse reproductive effects in women, the DOJ said.

Exxon also will be required to spend $1 million on a project to plant trees in Baytown, Texas, and purchase a $1.5 million mobile air quality monitoring vehicle for use by Louisiana’s environmental protection agency.
