Requires biannual certification of cooling towers

This bill requires building owners in New York City to submit biannual certification (in January and July) proving cooling towers were inspected, tested, cleaned, and disinfected according to health rules. It mandates weekly microbial testing during use and requires immediate cleaning if unsafe levels are found. Owners face increased penalties: $2,500 for a first violation, $7,000 for repeat offenses, and up to $12,500 if violations cause serious injury or death. The law directly affects all commercial and residential building operators with cooling towers, focusing on preventing health risks from contaminated water systems.
