Statement on Xcel Energy shutdown of Monticello nuclear plant

The Minnesota Pollution Control Agency and Minnesota Department of Health are encouraged that Xcel Energy is taking immediate action to address the recurring issue of water containing tritium leaking from the Monticello Nuclear Generating Plant.

State agencies were made aware this afternoon of an additional water leak at the Monticello facility following previous news about the leak of 400,000 gallons of water containing tritium. In the State Duty Office report filed today, Xcel Energy states that the new leak, located near the spot of the previously reported release, is still ongoing.

State agencies have no evidence at this point to indicate a current or imminent risk to the public and will continue to monitor groundwater samples. Should an imminent risk arise, we will inform the public promptly.

We encourage the U.S. Nuclear Regulatory Commission (NRC), which has regulatory oversight of the plant’s operations, to share ongoing public communications on the leak and on mitigation efforts to help residents best understand the situation.

The Minnesota Pollution Control Agency and the Minnesota Department of Health will continue to review Xcel’s response to the groundwater contamination and oversee the recovery, storage, and disposal of the impacted groundwater. We will also continue to coordinate with city, county, and other local officials to make sure the public is kept informed of developments.
