A 10-mile stretch of the Lower Mississippi River was closed Friday due a mysterious white haze, the U.S. Coast Guard said.
Coast Guard watchstanders received reports of the haze at 9 a.m. and quickly closed the Mississippi River from mile marker 205 to 215 near Plaquemine Point in Louisiana.
Local fire departments, Louisiana Department of Environmental Quality, Louisiana State Police and the Coast Guard all responded, conducting air monitoring both on and off the river. Air monitoring showed no measurable levels of chemicals in the air and the mysterious haze was not located, the Coast Guard said. The initial source or cause of the reported haze is still unknown.
The Coast Guard said it was determined that there is no danger to waterways or surrounding communities and the Lower Mississippi River was been reopened to all traffic.
The Coast Guard did not say whether or not they thought the ‘white haze’ may have just been some fog.
