ST. PAUL, MN (KDAL) - The Minnesota Pollution Control Agency has penalized the Hibbing Utilities Commission for air quality violations at its electric and heating plant. The district heating plant uses biomass and coal fired boilers to produce electricity and steam heat for downtown Hibbing buildings. Those boilers have been the source of excess particulate matter and carbon monoxide emissions since 2008. The Utilities Commission has submitted an 18 item compliance plan to eliminate the carbon monoxide violations and properly operate and maintain the filter equipment. They will pay a 17,250 dollar civil penalty and spend an equal amount to perform voluntary actions to reduce dust emissions.
