The Minnesota Public Utilities Commission recently approved a motion that installation of new environmental controls at the Boswell Energy Center would not require an environmental assessment worksheet, allowing the project to move forward in the regulatory process.
The controls are to be installed on the 585 MW capacity Unit 4 of the coal-fired power plant and will reduce mercury emissions by 90 percent, according to Boswell owner Minnesota Power. The project, which was first announced in May 2012, will meet requirements in the Mercury Air Toxics Standards Rule and the Minnesota Mercury Emission Reduction Act.
According to Minnesota Power, the project at Boswell Unit 4, along with $355 million in other emission reduction investments made by the company since 2006, will result in system-wide emission reductions of 70 percent by 2016.
Minnesota Power plans to begin construction on the $350 million project this summer, pending approval of an air permit from the MPCA.
