According to Sedalia Fire Chief Matt Irwin, The incident was deemed stabilized as of 11:15 a.m. However, the immediate area remains closed as an overabundance of caution, he said.

Irwin said a tank failure behind MWP is what caused the incident, reported just before 7:30 a.m. Hydrochloric acid was released into the air, with prevailing winds at the time around 8 - 9 miles per hour.

The confinement system worked as it was supposed to, Irwin added. Some of the acid spilled onto a set of metal stairs, which reacted and caused the plume of smoke to rise.

The Sedalia Fire Department poured 10,000 gallons of water into the confinement system, and there no hazard for area residents to be concerned about at the moment. Employees of Pro Energy were asked to shelter in place when the incident first happened.

The prevailing winds are no out of the east and south.

MPW will bring in a professional clean-up crew, Irwin said.

Irwin noted that Hydrochloric Acid is considered a breathing hazard.
