St. Paul, MN (NNCNOW.com) - The Minnesota Public Utilities Commission has cleared the way for the environmental retrofitting of Boswell Energy Center's Unit Four.
Minnesota Power is applauding the move which it says will help reduce mercury emissions by 90 percent at the company's largest and newest coal-fired unit.
The $350 million project will meet requirements in the EPA's Mercury Air Toxics Standards Rule and the Minnesota Mercury Emission Reduction Act.
The Commission approved a motion that the installation of new environmental controls did not require an environmental assessment worksheet.
The Minnesota Center for Environmental Advocacy had petitioned for a worksheet.
Thursday's decision will allow Minnesota Power to progress on the project without what the company calls an unjustified and costly delay.
Construction will begin this summer.
