ExxonMobil reaches $300m clean air settlement, facility upgrades with US regulators

ExxonMobil will spend $300 million to upgrade eight US chemical facilities and resolve allegations it spewed excess emissions of benzene and other dangerous chemicals into the air, US regulators announced Tuesday.

The US petroleum giant will install new pollution controls and monitoring equipment at plants in Texas and Louisiana, according to a consent decree announced by the Justice Department, the US Environmental Protection Agency and the Louisiana Department of Environmental Quality.

ExxonMobil also will pay a $2.5 million civil penalty.

“This settlement will improve air quality in Texas and Louisiana by eliminating thousands of tons of harmful air pollution each year,” said acting assistant attorney general Jeffrey Wood of the Justice Department’s environment and natural resources division.

The settlement comes after regulators charged that ExxonMobil failed to properly operate and monitor industrial flares, leading to excess emissions from the units, the Justice Department said in a news release.

Industrial flares are used at such chemical sites to burn off excess chemicals. Well-run flares do better at combusting harmful pollutants, such as benzene, a human carcinogen, and volatile organic compounds, which can exacerbate asthma and other respiratory ills.

As part of the settlement, ExxonMobil will upgrade flares at 26 industrial flares at the Texas and Louisiana plants, a shift that is expected to reduce emissions of volatile organic compounds by 7,000 tons a year and toxic air pollutants by 1,500 tons a year, regulators said.

The settlement requires the company to spend $1 million on a project to plant trees as a buffer to airborne pollutants.
