This bill introduces a new section to South Dakota law that allows lodging establishments with fifteen or fewer sleeping rooms to apply for a permit to use biological filtration systems in their water recreational facilities. The bill stipulates that only establishments with a valid permit may utilize such systems, which must be renewed annually. To obtain a permit, establishments must demonstrate compliance with water quality outcomes set by the department and ensure that their facilities meet minimum public health and safety requirements. Additionally, the bill mandates annual inspections of the biological filtration systems, with the possibility of permit revocation for establishments that fail inspections.

The legislation also outlines the department's authority to establish rules regarding the application process for permits, reapplication procedures after failed inspections, routine maintenance requirements for the filtration systems, permit fees (capped at fifty dollars), and water quality testing procedures. A biological filtration system is defined as one that filters water using natural processes, such as plants and beneficial microbes, without relying on continuous chemical disinfectants.
