Regulatory Context

Ohio regulates isolated wetlands under the Ohio Isolated Wetland Permit program, filling the gap left by federal jurisdiction post-SWANCC (2001) and Rapanos (2006). The Huntington District covers the Ohio River corridor and most of the state. Ohio EPA uses the Ohio Rapid Assessment Method (ORAM) to assess wetland quality for 401 certification purposes, requiring delineators to understand both standard methods and Ohio-specific assessment tools.
