Utah’s most famous salt mine is expected to close this week after a massive spill of sand from a sand mining operation.
The state Department of Mineral Resources said Thursday that the spill occurred at a salt mine in Veruca, south of Salt Lake City.
State law requires the state to close the mines if there is a health risk to humans or the environment.
The mine was operated by Veruca Mineral Products, based in Salt Lake.
State regulators are inspecting the mine, which is about 20 miles north of Salt City.
It has about 1.5 million cubic yards of sand.
A sand mine has long been a source of controversy in Utah.
It was the subject of a 2012 federal lawsuit alleging it contaminated drinking water wells in the state.
A lawsuit against the state over the spill, which spilled more than 1,000 gallons of sand, was dismissed in June by a federal judge.
The state says it was not aware of the spill until a complaint was filed.
