Concerning water recreation facilities.

HB 1684 updates Washington State's definitions and regulatory requirements for water recreation facilities, including pools, water slides, wave pools, and natural areas with artificial boundaries used for public recreation. It clarifies that permits are required for construction or modifications of such facilities and ensures operators need only apply to one agency (local health jurisdiction or the state Department of Health), not both. The bill maintains exemptions for small residential complexes (under 15 units) and natural water areas like lakes or streams not intended for public recreation. These changes streamline oversight while requiring facilities to meet safety, sanitation, and water quality standards under updated state rules.
