Permitting Assistance, Wetland Mitigation and Stream Relocation


King & MacGregor Environmental (KME) has been the primary natural resource consultant for Hemlock Semiconductor Corporation (HSC) since 1996. HSC is the world's leading producer of polycrystalline, a base material utilized for solar panel and computer chip manufacturing. KME has been able to assist HSC in obtaining Michigan Department of Environmental Quality (MDEQ) and U.S. Environmental Protection Agency (EPA) permits for three major facility expansions requiring over 40 acres of wetland impact and over two billion dollars of capital investment. KME has designed and supervised the construction of over 50 acres of compensatory wetland mitigation. Each expansion has involved a complex set of circumstances, extensive interagency coordination, and time sensitive results while maintaining confidentiality over proprietary processes.
