About 8,200 gallons of hydrochloric acid leaked from a tank at a Kennecott facility in Magna following Wednesday morning’s earthquake.

Unified Fire Authority Chief Dan Petersen said most of the chemical, which leaked out of a 12,000-gallon tank, was contained to a catch basin in the facility. It was fully contained within the Kennecott building, he said.

State Route 201 will be closed in the area as crews continue cleaning up the
