The WET-NZ deployment is authorized by a Nationwide Permit from the US Army Corps of Engineers, as required under Section 404 of the Clean Water Act and Section 10 of the Rivers and Harbors Act. In addition, the Fish and Wildlife Service and the National Marine Fisheries Service evaluated the project to ensure it would not adversely affect threatened or endangered species or their critical habitats, pursuant to the federal Endangered Species Act. The project is also authorized by a Private Aids to Navigation Permit from the US Coast Guard for the navigational markers and lighting in and around the project site.
The project also received various permissions from the State of Oregon, including a Temporary Use Authorization from the Department of State Lands, as well as review by the Department of Fish and Wildlife. In accordance with the Coastal Zone Management Act, the Department of Land Conservation and Development reviewed the project for consistency with the goals and policies of the Oregon Coastal Management Plan, which include the recently revised Territorial Sea Plan. Similarly, the Lincoln County Department of Planning and Development reviewed the project to ensure compliance with local land use plans.
In addition to the reviews conducted as part of the permitting process, the US Department of Energy prepared an Environmental Assessment for its funding of the project, in accordance with the National Environmental Policy Act. After reviewing public and agency comments, DOE issued a Finding of No Significant Impact for the project.
