Xcel Energy - Monticello Nuclear Generating Facility - Wastewater Permit
We invite you to comment on the draft wastewater permit for the Xcel Energy - Monticello nuclear generating facility.
This permit allows Xcel Energy - Monticello nuclear generating facility to discharge treated wastewater to the Mississippi River. Water used at the plant for cooling and fire protection is withdrawn from wells and the Mississippi River, is treated after use before being discharged back to the Mississippi River. A number of new pollutant limits and monitoring regulations were added to the permit.
Wastewater from industrial and commercial sources may contain pollutants at levels that could adversely affect the water quality in area wetlands, streams, rivers, and lakes. Water quality permits - or National Pollutant Discharge Elimination System (NPDES) permits - establish specific limits and requirements to protect Minnesota's surface and groundwater quality. All wastewater must be treated before it goes into surface water to protect human health and aquatic life. Permits are regularly reviewed and updated as they expire, allowing the MPCA to incorporate new information about the impacts of pollutants on the environment in future permits.
All fields are optional unless otherwise indicated.
