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 existing public health and safety standards. Additionally, the bill mandates annual inspections of the biological filtration systems, with provisions for permit revocation in the event of a failed inspection.

The legislation also empowers the department to establish rules regarding the application process for permits, reapplication procedures after failed inspections, maintenance requirements for the filtration systems, permit fees (capped at fifty dollars), and water quality testing protocols. A biological filtration system is defined as one that uses natural processes, such as plants and beneficial microbes, rather than relying on continuous chemical disinfectants. This bill aims to promote environmentally friendly water filtration methods in smaller lodging facilities while ensuring public health and safety standards are maintained.
