Coast Guard Responds to Report of Mysterious Haze

The U.S. Coast Guard temporarily closed the Mississippi River from mile marker 205 to 215 near Plaquemine Point due to an unknown white haze, Friday morning

Watchstanders at Coast Guard Marine Safety Unit Baton Rouge received notifications about the haze at 9 a.m.

The Coast Guard, in conjunction with several first responders including local parish fire departments, Louisiana Department of Environmental Quality, and Louisiana State Police, responded. Air monitoring was conducted, both on and off the river, throughout the response.  Air monitoring showed no measurable levels of chemicals in the air and the mysterious haze was not located. The initial source or cause of the reported haze remains unknown.

There is no danger to waterways or the surrounding communities and the Lower Mississippi River has been reopened to all traffic.
