Tennessee Code Title 68. Health, Safety and Environmental Protection § 68-14-323

The commissioner may grant waivers from rules and regulations governing public swimming pools in excess of fifty thousand square feet (50,000 sq. ft.), or may promulgate additional rules and regulations governing such pools. Waivers or regulations shall be designed to protect the health, safety, and welfare of patrons when adequate standards do not exist to provide sufficient guidance regarding preventive maintenance, pool structure, operating systems, water turnover, circulatory systems, or innovative designs due to the size of the public swimming pools or due to the source of water supply for such pools.
