Michigan Bill Proposes Aligning State Wetland Protections with Narrowed Federal Standards

A new bill introduced in the Michigan House, HB 5536, seeks to redefine state wetlands to align with recently narrowed federal standards under the Clean Water Act. Sponsored by Republican Representative David Martin, the legislation aims to reduce regulatory burdens on farmers, developers, and residents who face confusing and costly permitting requirements. However, environmental advocates warn that adopting the stricter federal definition, influenced by the 2023 Sackett v. EPA Supreme Court decision, would strip protections from hundreds of thousands of acres of wetlands. Critics argue this change ignores the ecological importance of wetlands without continuous surface connections to navigable waters, potentially degrading habitats and water quality. The proposal comes as Michigan faces increased flooding risks and reduced state funding for wetland restoration. While supporters claim the bill enhances clarity and trust in government operations, opponents highlight that it could leave up to 95 percent of Michigan’s regulatory wetlands vulnerable to development, threatening critical natural buffers against pollution and extreme weather events.
