New Clean Water Act Regulations

In late May, the U.S. Supreme Court issued a landmark Clean Water Act (CWA) decision, significantly narrowing the scope of what “Waters of The United States” means under federal law. This new interpretation reduces the number of wetlands that are regulated under the CWA. In Oregon, Washington, and California, state wetland regulations continue to be strong, and impacts to wetlands will continue to require permitting and mitigation. MB&G’s environmental services group are closely following these changes and have extensive experience with regulatory compliance needs triggered by Sections 404/401 of the Clean Water Act, and other federal, state, and local environmental regulations.
