Comparison: State vs. Federal

Rules. In addition to the federal dredge and fill permit requirements administered by the U.S. Army Corps of Engineers (Corps) and the U.S. Environmental Protection Agency (EPA), Oregon has a separate permitting program for removal and fill activities that may affect waters of the state. See the national section WETLANDS, and contact the Oregon Department of Environmental Quality (DEQ) for more information. In addition to federal and state regulation, a third level of regulation governs development that may affect wetlands—local governments must prepare and submit to the Oregon Division of State Lands (DSL) local Wetland Conservation Plans (WCPs). Contact the DSL for local plan requirements.

Under state law, all "waters of the state" are protected and defined as natural waterways, including all tidal and nontidal bays, intermittent streams, wetlands and other bodies, both navigable and nonnavigable.
