Hibbing, MN (NNCNOW.com) --- The Minnesota Pollution Control Agency has penalized the Hibbing Utilities Commission for air quality violations at its electricity and heating plant in Hibbing.
Officials say the commission’s boilers have been the source of excess dust and carbon monoxide emissions for more than five years. Subsequent enforcement actions have not resulted in improved air quality and permit compliance.
The latest requirement of adding natural gas as a supplemental fuel source for the wood-fired boilers should increase boiler efficiency and eliminate future carbon monoxide violations.
The Hibbing Public Utilities Commission must complete eighteen required corrective actions and will pay a penalty of $17,250 . It will also spend the same amount to make voluntary dust-emission-control improvements.
