PORT HURON, Michigan — A long-idle paper manufacturing site in Port Huron is moving closer to redevelopment with new state support. Governor Gretchen Whitmer announced Wednesday that Legacy Port Huron Paper Company plans a 24.5-million-dollar investment at the former Domtar paper mill site in Port Huron. …According to the Michigan Economic Development Corporation, the Port Huron project will be supported by a one-million-dollar performance-based grant. The full funds will only be distributed if the company meets agreed-upon investment and job-creation milestones. Legacy Port Huron Paper, a subsidiary of the Ontario-based BMI Group, plans to repurpose nearly 400,000 square feet across nine buildings at the former Domtar site, converting the space for paper manufacturing, warehousing, and other industrial uses.
