The Minnesota Pollution Control Agency (MPCA) is leading and coordinating the State of Minnesota’s oversight of the Xcel Monticello Plant tritium release. The MPCA, along with the Minnesota Department of Health (MDH) and Minnesota Department of Natural Resources (DNR), continues to review and assess Xcel’s actions to contain and prevent tritiated groundwater from discharging into the Mississippi River.
Each agency has specific roles. The MPCA provides input on the storage and management of tritiated water on the Xcel site and expediates any permit requests. MDH assesses the tritium release’s risk to human health and provides public updates regarding the risk. The DNR assesses ecological risks due to tritium concentrations and prepared to conduct fish and wildlife sampling, if needed.
The State continues to monitor and oversee Xcel’s activities to contain the tritium release and assess any potential impacts of tritium discharging to the Mississippi River. In addition, the State is reviewing permitting requests for storing the tritium groundwater. The MPCA and other state agencies will continue to provide timely public updates as significant developments in the monitoring and cleanup occur.
