Is Minnesota Power’s Boswell 3 Environmental Improvement Plan (Boswell 3 Plan) required (i.e., needed now to comply with new state or federal air quality standards)?
Yes. Minnesota Power must make significant reductions in mercury, oxides of nitrogen (NOx), sulfur dioxide (SO2) and particulate matter (PM) emissions at Boswell Unit 3 to meet the requirements of the Mercury Emissions Reduction Act of 2006 and comply with other recently established and fast-approaching state and federal emission requirements.
