Kennecott Refinery Evacuated After Chemical Spill

MAGNA, Utah — A refinery near the Kennecott mine was evacuated and shut down after a 5.7-magnitude earthquake rocked the Wasatch Front, causing a chemical spill in a warehouse building. The leak has since been contained.

Crews have been monitoring the scene and working to clean up the spill, but it could still be days before the refinery will re-open.

Witnesses reported seeing plumes of smoke coming from the area a few hours after an earthquake rocked northern Utah at 7:09 a.m. Wednesday.

Firefighters from eight different agencies responded to the scene, including the Utah National Guard. The 85th Civil Support Team was deployed by Governor Gary Herbert just after noon to assess the damage.

Unified Fire Authority Chief Dan Petersen said a material had spilled inside a large warehouse on the Kennecott property as a result of the quake. They discovered about 8,200 gallons of a 12,000-gallon tank had leaked out onto the catch basin, which caused plumes to rise from the building.

Crews were able to identify the material as hydrochloric acid. They were originally concerned that the chemical had mixed with something, potentially causing more danger to the public, but they were able to rule that out.

Most of the emergency responders ended up simply standing by near Saltair in the event that their help would be needed.

“We’ve provided some air-monitoring and some other equipment,” said Mathew McFarland, UFA spokesman. “We’ve spoken directly with them throughout the process (to) help them determine what the best course of action is.”

McFarland said UFA has trained alongside Kennecott teams often to be ready for situations like this.

All operations have been temporarily halted as a precaution, but Kennecott officials said all team members and contractors were safe and accounted for. No was injured in the spill or in response to the spill, and there was no immediate danger to the public.

Six hazmat crews have been left on site to monitor the situation. They’ve had to double-check the area for damage after each aftershock.

SR-201 was temporarily closed while crews completed an inspection of the tailings facility. It eventually opened back up after about 30 hours.

Officials said the refinery will re-open once they feel it is safe to do so.
