Huber Engineered Woods has resubmitted an environmental analysis for its planned $440 million Iron Range plant following pushback from environmentalists, business groups and a rival mill that demanded a more thorough review.
Last year, the state Legislature approved a carve-out for the plant allowing it to, for now, avoid undergoing the lengthier environmental impact statement process typically required for a project of this size.
The updated environmental assessment worksheet (EAW) amends the initial version of the shorter form filed last fall. It provides more detail on Minnesota's timber supply and specifics on greenhouse gas emissions for Huber's plant in Cohasset, Minn., where it will make oriented strand board.
The facility will emit nearly 450,000 tons of carbon dioxide per year, making it the state's 13th largest generator of greenhouse gases, according to the U.S. Environmental Protection Agency.
Huber says "the project will be a net carbon sink" as those emissions will be more than offset by the use of "carbon-neutral" wood-burning furnaces and carbon captured in the wood products it sells.
The Minnesota Center for Environmental Advocacy wrote that oriented strand board, which is similar to particle board, "may have some positive climate effects, due to the sequestration of carbon within the product and its use in place of other, more carbon-intensive construction materials."
But the group urged a deeper review and wrote last fall that "like other corporations engaged in activities that affect Minnesota's environment, [Huber] has the resources and the responsibility to fully study and disclose those impacts before receiving governmental approval for this project."
The mill is expected to annually consume 400,000 cords of mostly aspen wood, or about 900,000 tons. The Bemidji Chamber of Commerce said last fall it opposed the project without an accounting of how an increased timber harvest would affect the environment — and West Fraser's Norbord mill in Solway, Minn.
