The federal government is now taking comments on alternatives to a project in western Colorado notorious for causing earthquakes.
The Bureau of Reclamation is looking for replacements for the Paradox Valley Unit, located in a remote part of western Colorado’s Montrose County. The agency released a draft environmental impact statement for those replacements Friday.
The project intercepts briny groundwater before it can seep into the Dolores River, and injects it deep underground, where it can lubricate fault lines. The project is meant to control salinity levels in the Dolores River, which is a tributary to the Colorado River. Elevated salt levels degrade water quality and increase costs to treat the river’s water.
The most recent quake in March of this year was large enough to cause the facility to shut down. Since then, Paradox Valley has experienced more than 30 smaller earthquakes, likely caused by lingering pressure created by the facility’s operations.
The federal government is asking for public comments on four alternatives to the existing well, which the Bureau of Reclamation says has reached the end of its usable life.
Those alternatives are:
