B. No specific spillway design flood is required for a dam that meets the criteria established in subsection A of this section, although the recommended minimum spillway design flood is a 50-year flood.

C. Any owner of an impounding structure electing to utilize the requirements of subsection A of this section shall otherwise comply with all other requirements of this chapter applicable to low hazard impounding structures.

D. The owner shall notify the department immediately of any change in circumstances that would cause the impounding structure to no longer qualify to utilize the provisions of this section.
