Wetlands Information Resource Locator

Most states have enacted laws and regulations to protect wetlands. In many cases, these rules are established to define the state's role in the §404 permit/§401 certification process. However, some state laws have other impacts. For example, states may adopt a definition of wetlands or regulated activities that are different than the federal definitions. This could for example, qualify an area as a wetland that does not meet the federal definition.
