No river or river segment may be eligible as a state scenic river and accorded the protection of this chapter, except upon formal action by the department. Following action by the department declaring a river or river segment eligible as a state scenic river, the department shall publish a notice of the eligibility in the State Register and provide written notice to the Department of Administration, the Department of Revenue, and the affected units of local government. Notice of eligibility also must be published in a newspaper of general circulation in the State to apprise interested parties of the opportunities under Section 49-29-100. The notice must describe the boundaries of the river or river segment. Following notice of eligibility, the department shall submit the same to the General Assembly for review. No river or river segment may be designated a state scenic river until the General Assembly has duly enacted legislation ratifying such designation.
