The EPA is investigating whether Westwater Resources is violating Clean Water Act rules when it supplies solar power to nearby homes.
The solar company said it would work with the agency to help resolve the matter.
The EPA has been investigating whether solar power is harming water resources, and Westwater says it is complying with Clean Water act rules.
Westwater said in a statement that it would “exercise its full rights and authority” to address the issue.
The agency said it was still working to resolve the issue with the company, which is headquartered in the state of Oregon.
The company’s solar panels are part of a series of projects it’s making in Oregon to reduce water pollution, which has led to concerns about the environmental impact of its installations.
Earlier this month, the EPA confirmed it was investigating a series to address water pollution in Oregon.
