Utah's $1.9 billion claim against the Environmental Protection Agency for a multi-state mine waste spill says Utah's water, soil and wildlife were damaged, but it offers no specifics.
State officials provided a copy of the claim to The Associated Press Wednesday.
The claim stems from the August 2015 release of 3 million gallons of wastewater from an inactive gold mine in southwestern Colorado. An EPA-led contractor crew inadvertently triggered the spill.
Rivers in Colorado, New Mexico and Utah were polluted. Indian lands were also affected.
Farmers, ranchers and utilities temporarily stopped drawing water from the rivers, and rafting companies had to suspend operations.
Utah's claim from the spill is believed to be the largest of 144 filed under a law that allows people to seek government compensation without a lawsuit.
