Statement from the Mayor on the Xcel Energy Shutdown of the Monticello Nuclear Plant

The safety of Monticello’s residents has been and continues to be our number one priority. We are glad Xcel Energy was closely monitoring the situation and decided to shut down the plant to make permanent repairs immediately to address the recurring issue of water containing tritium leaking from the Monticello Nuclear Generating Plant.  

City Staff have spoken with Xcel Energy and learned that it was discovered yesterday that the temporary patch on the pipe at the Monticello Plant began leaking again. Xcel Energy is following protocols and submitted a notice to the Nuclear Regulatory Commission and the State of Minnesota. Those notices will be posted as a secondary leak alert; however, Xcel Energy officials want to emphasize to the Monticello community that this is not a new leak in a new location on the plant, but the existing leak location. They would also like to note that this leak did not leave their facility’s property and merged in the same area as the existing tritium water accumulation.

The Minnesota Pollution Control Agency (MPCA) says, “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. The MPCA 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.”

The public water system operated by the City of Monticello has been unaffected by the leak at Xcel. The leak occurred outside of Monticello’s Wellhead Protection Area, the specific area surrounding our public water supply that contributes groundwater to municipal wells. We will continue to monitor the situation and are testing the municipal water supply as a precaution.

If residents would like to know more about the situation, Xcel Energy and staff from the State of Minnesota will be hosting informational open houses for the Monticello community on Friday, March 24 from 10 a.m. to 1 p.m. and Monday, March 27 from 5 p.m. to 8 p.m. in the Bridge Room at the Monticello Community Center. 

The public is invited to stop by whenever they’re available during the scheduled times, get their questions answered, and learn more about the resources available for our community. If you have any questions about the open houses, please visit Xcel Energy’s Contact Us page.

A Statement from the City of Monticello:

We understand the notifications today from Xcel Energy and the Minnesota Pollution Control Agency will be particularly concerning to our community.

The public water system operated by the City of Monticello has been unaffected by the leak at Xcel. The leak occurred outside of Monticello’s Wellhead Protection Area, the specific area surrounding our public water supply that contributes groundwater to municipal wells.

We encourage members of the public to use the resources and contact information provided by Xcel Energy for questions about the leak and the plant. City leaders will continue to participate in the process on behalf of the community and share information as it becomes available. Helpful information, FAQs, and other resources for residents regarding the Xcel water leak in Monticello can be found here on our website.

A Statement from Xcel Energy regarding the progress to recover and treat water leaked at the Monticello Nuclear Plant:

MINNEAPOLIS (March 16, 2023) – Xcel Energy today reported on steps taken to contain and manage a water leak detected by routine groundwater monitoring systems at its Monticello Nuclear Generating Plant late last year. Xcel Energy took swift action to contain the leak to the plant site, which poses no health and safety risk to the local community or the environment. 

Xcel Energy notified the Nuclear Regulatory Commission (NRC) as well as the state on Nov. 22, 2022, the day the leak was confirmed. The company has since coordinated regularly with state and federal regulators, as well as local officials. The company has been pumping, storing, treating and reusing the leaked water, which contains levels of tritium that are below the NRC safety thresholds. Tritium is a compound that is naturally present in the environment and is commonly created in the operation of nuclear power plants. It emits low levels of radiation, similar to everyday materials people use and the food we all eat.   

Ongoing monitoring from over two dozen on-site monitoring wells confirms that the leaked water is fully contained on-site and has not been detected beyond the facility or in any local drinking water. State agencies continue to monitor Xcel Energy’s remediation work to ensure the continued safety of the local community and surrounding environment.

“We have taken comprehensive measures to address this situation on-site at the plant. While this leak does not pose a risk to the public or the environment, we take this very seriously and are working to safely address the situation,” said Chris Clark, president of Xcel Energy–Minnesota, North Dakota and South Dakota. “We continue to gather and treat all potentially affected water while regularly monitoring nearby groundwater sources. We will continue to partner with local groundwater specialists, and we remain in close cooperation with the MPCA, along with other state and federal regulators and our local community throughout the remediation effort.”

The radiation levels in the leaked water are so low that, even if the water were to reach a drinking water source, it would be as safe for a person to drink as the food they eat on an average day. To date, Xcel Energy has recovered about 25% of the tritium released and will work to recover the rest over the course of the next year. 

Xcel Energy identified the source of the leak as a water pipe running between two buildings. To contain the leak, the facility is diverting the water to an in-plant water treatment system, preventing additional water from leaving the plant, and will install a permanent solution in the spring of 2023. A thorough inspection was conducted of all piping in all locations where a leak could occur, to verify that no other area of the facility was facing this issue. The company will also be examining the one pipe that did leak in a laboratory to better understand why this happened. These findings will help Xcel Energy ensure it does not encounter the same issue moving forward.

The company has constructed new monitoring and recovery wells and has increased the frequency of measurements from its network of over two-dozen groundwater monitoring wells to enhance its monitoring and recovery efforts. Large storage tanks are also likely to be constructed on-site to store recovered water until it can be treated and reused.

The nuclear industry initiated an advanced groundwater monitoring program in 2007, which the Monticello plant has implemented, and industry experience with the successful containment and treatment of this substance has helped inform steps that have been taken at the plant.

Media availability: Interviews are available with Xcel Energy as well as with the Minnesota Pollution Control Agency and other state agencies.

The Minnesota Pollution Control Agency (MPCA), in coordination with the Minnesota Department of Health, and the Minnesota Department of Natural Resources, is monitoring Xcel Energy’s efforts to clean up a release of water contaminated with tritium detected at the company’s Monticello nuclear generating plant.

Xcel Energy reported the leak to the Minnesota Duty Officer and the Nuclear Regulatory Commission (NRC) in late November 2022 after finding unusual results during routine groundwater monitoring. The leak has been stopped and has not reached the Mississippi River or contaminated drinking water sources. There is no evidence at this time to indicate a risk to any drinking water wells in the vicinity of the plant.  

Tritium is a naturally occurring radioactive form of hydrogen that is produced in the atmosphere. It is a byproduct of the production of electricity by nuclear power plants.

State agencies are actively reviewing data, including well sampling results provided by Xcel Energy, and overseeing remediation efforts. The company continues to update state agencies about cleanup efforts and share data from ongoing groundwater monitoring.

The company reported about 400,000 gallons of the water containing tritium leaked from a water pipe running between two buildings at its Monticello facility. The leak was stopped and the company is monitoring the groundwater plume through two dozen wells. Xcel Energy is also pumping contaminated groundwater through extraction wells. The pumped water is being stored and some is being reused on site.

“Our top priority is protecting residents and the environment, and the MPCA is working closely with other state agencies to oversee Xcel Energy’s monitoring data and cleanup activities,” said Kirk Koudelka, MPCA assistant commissioner for land and strategic initiatives. “We are working to ensure this cleanup is concluded as thoroughly as possible with minimal or no risk to drinking water supplies.”

Xcel Energy is exploring building aboveground storage tanks or installing a retention pond to store water containing tritium that has been collected during ongoing recovery activities. The company is also considering options for treatment, reuse, or final disposal of the collected tritium and water. Minnesota state agencies will review any options selected by Xcel Energy.

City Council Approves ‘No Mow May’

Monticello, MN – On Monday, March 13 City Council approved ‘No Mow May’ in Monticello. For the second consecutive year, the City will suspend nuisance enforcement on grass lengths during the month of May. 

No Mow May is a conservation initiative recommended by the Minnesota DNR. The goal is to allow grass to grow unmown during the month, creating habitat and forage for early season pollinators. Pollinators play a critical role in our food supply and keeping our natural resources healthy. No Mow May1

Residents are encouraged to suspend mowing for the month, but it is not required. There are other ways you can help Minnesota’s pollinators if you want to continue to mow. The public can also plant bee flowers and native plants as well as keep plants pesticide free.

During the month of May, City staff will continue mowing around rental structures in the parks, and around City buildings to ensure accessibility.  We’re excited to participate in No Mow May in other ways, like adding native prairie grasses and wildflowers throughout our parks system.

If residents plan on participating, please note that enforcement will resume Thursday, June 1. At that time, all lawns must be maintained per the City’s Code (grass cannot be over 8 inches). We recommend giving yourself a few days to safely manage your lawn. Here are a couple of tips from the University of Minnesota for mowing long grass:

  • Adjust your mower to the highest setting, you will have to make more than one pass over the grass.
  • After you have reduced the grass height to a more manageable length, change the mower setting by reducing the height of the blade, before making a second pass.
  • Do not cut more than 1/3 of the grass blade at a time in a single mowing. This helps prevent root stress and promotes a healthy lawn.

For more information visit the City’s website or check out the University of Minnesota’s Bee Lab for other actions you can take to help our local pollinators.
