US pressure group Louisiana Environmental Action Network has filed a lawsuit against ExxonMobil, claiming the oil and petrochemicals group’s Baton Rouge, Louisiana, chemical plant continues to violate the US Clean Air Act despite a 2014 settlement with the state.

The suit alleges that pollution from the plant jeopardizes the health of nearby residents of a predominantly black, low-income area.

In 2014, the state called for ExxonMobil to pay more than $2.3 million to resolve alleged permit violations over chemical releases and spills at four of its Louisiana facilities. However, but the environmental group claims the Baton Rouge plant has continued to violate environmental regulations and failed to properly notify the state Department of Environmental Quality.
