Officials said a shelter has been opened at the Amite Community Center, 101 W. Chestnut St., Amite. The oil plant in Roseland where a mid-day explosion turned into a massive fire has a history of environmental regulations in recent years, including a $250,000 fine levied just two years ago. That fine stemmed from an oil spill into a nearby roadside ditch in 2021, according to court records of the settlement. In the settlement, Smitty’s did not admit to liability, but agreed to pay the fine pursuant findings by the Louisiana Department of Environmental Quality. Federal and state records show that Smitty’s Supply, Inc. also was cited for violations and forced to pay fines in several other mishaps at the plant over the past six years.
