The Environmental Protection Agency (EPA) withdrew a permit Monday it gave to the Four Corners Power Plant. The EPA said it will review the impact of pollutants the plant discharges into nearby waterways.

This comes after environmental groups filed a lawsuit saying the EPA did not do their due diligence before renewing the APS-operated plant's discharge permit.

The Clean Water Act requires that a special permit be issued for the discharging of pollutants into navigable water. The one the EPA had earlier issued allowed the coal-fired Four Corners Power Plant to empty water from a man-made cooling pond named Morgan Lake into a wash that flows into the Chaco and San Juan Rivers.

The permit allows the plant to discharge set amounts of heavy metals, arsenic and other pollutants.

EPA anticipates publishing a draft of an updated permit in March.
