(1) All indoor pools, spas, or other water features and their decking areas that operate at night or that have insufficient natural light to meet the clarity requirements in ARM 37.115.1315 must install and use safe artificial light that is adequate to meet those clarity requirements at all times during operation of the pool, spa, or other water feature. Such lights shall be spaced to provide illumination so that all portions of the pool, spa, or other water feature, including the bottom, may be readily seen without glare.

(2) If lighting is not provided as required by this section, the facility operator shall not permit any use of the facility at any time there is insufficient light to clearly view the main drain of the pool from any location on the perimeter or deck surrounding the pool.
