ST. ROSE, La. -- Numerous residents from St. Rose reported smelling a strong chemical odor over the weekend as authorities in St. Charles Parish worked to pinpoint the source.
According to the St. Charles Parish Emergency Operations Center, residents first started reporting the odor Saturday morning. By Sunday evening, the Louisiana Department of Environmental Quality confirmed they had received numerous reports about the strong smell of sulfur.
After the odor dissipated Saturday, it returned Sunday morning, and increased in strength around 5 p.m. Sunday.
According to DEQ, either the International Matex Tank Terminals, or IMTT, facility in St Rose or Shell Asphalt facility in Norco are considered potential sources of the odor.
St. Charles Parish officials said Sunday that IMTT shut down its operations at 3 p.m. Sunday in case their facility is, in fact, the source of the odor.
The two companies were conducting air monitoring Sunday and "didn't detect any quantities harmful to human health," according to DEQ Press Secretary Greg Langley.
St. Charles emergency management officials, local fire departments and DEQ reps were at the facilities Sunday trying to pinpoint the source of the odor.
DEQ could return to conduct its own air monitoring Monday if the odor hasn't dissipated.
