Sulphur, LA, residents were reporting a stench in the air July 23 after a gas release from the CITGO refinery, officials said.
The gas emissions were caused by a unit upset at the site off Highway 108, said CITGO spokeswoman Dana Keel.
Dick Gremillion, director of Calcasieu’s Homeland Security and Emergency Preparedness, said he received word sulfur dioxide and hydrogen sulfide released from the refinery Sunday afternoon.
There were no evacuations from the refinery, no reported injuries, and no reported offsite impact from the incident, Gremillion said.
Keel released the following statement from CITGO:
“A unit upset took place at approximately 11: 00 a.m. on Jul 23, 2017 causing elevated emissions levels. All appropriate regulatory agencies have been notified. All personnel have been accounted for and no injuries have been reported. There is no action required by the surrounding community at the present time. Perimeter and on-site air monitoring are on-going and operations are returning to normal. The cause of the incident is under investigation. As always, the safety of our employees and the surrounding community remains our first priority.”
