Energy Fuels has received approval from the US Environmental Protection Agency (EPA) to construct tailings impoundment and evaporation pond facilities for the Piñon Ridge uranium and vanadium mill.

The approval follows the radioactive materials licence received in March and allows the firm to construct and operate the Piñon Ridge mill.

The Piñon Ridge Mill will be located in Uravan Mineral Belt, which is the most significant uranium and vanadium producing region in the US.

Currently, the firm is awaiting the construction permit from the Colorado Air Pollution Control Division for non-radioactive air emissions.

The firm is also acquiring, permitting and rehabilitating additional mines in the region with significant remaining uranium and vanadium resources.
