The Details

What you need

Under the federal Clean Water Act, a 401 Water Quality Certification is required for certain activities in wetlands and waters. This law gives states the authority to review projects that must obtain federal licenses or permits and that result in a discharge to state waters, including excavating and fill in wetlands. The purpose of state 401 review is to ensure that a project will comply with state water-quality standards and other appropriate requirements of state law.
