Requires registration, inspection, testing, cleaning, and disinfection of cooling towers to control outbreaks of Legionnaire's Disease.

This bill requires building owners with cooling towers to register them with the Department of Health, conduct quarterly inspections and testing for contaminants and Legionella bacteria, and maintain proper cleaning and disinfection schedules. Owners must register new cooling towers before operation and existing towers within 30 days of the law's effective date, and must clean and disinfect towers within 48 hours if test results indicate maintenance issues or within 24 hours for serious health threats. Building owners must annually certify compliance by November 1 and maintain records of inspections, tests, and maintenance for three years. Non-compliance can result in civil penalties up to $10,000 for violations causing serious injury or death, or criminal charges for willful violations. The bill directly affects building owners who operate cooling towers, which are part of recirculated water systems in buildings.
