As a result of Section 404 of the Clean Water Act, there is not only a professional interest but a legal mandate to protect wetland resources in the United States. Jurisdictional wetlands can no longer be destroyed or degraded without review by a regulatory agency. The construction or restoration of wetlands as mitigation for unavoidable impacts to existing wetlands is a common agency action. In West Virginia, dozens of wetlands have been constructed. Some have been mitigated for extractive mineral operations and highway construction; others have been created as treatment facilities for land fill leachate and domestic sewage plant discharge. The use of constructed wetlands for mitigation is commonly associated with highway construction projects. The West Virginia Division of Highways (DOH) has constructed or restored more than 12 wetlands as mitigation for unavoidable environmental impacts. Because wetland construction is a relatively new technology, few wetland designs have been thoroughly evaluated. In the central Appalachian Mountain region, there have been no published evaluations of the ecological functioning of constructed wetlands. |
