Protection Against Legionella: Cooling Tower Requirements
Cooling Towers and Legionella Protection
Subpart 4-1 of the NYS Sanitary Code was passed in July 2016 requiring all cooling tower owners and/or operators in NY State to sample, maintain, register, disinfect, and notify the local health department and the public of any elevated levels of legionella.
Under the Legionella regulation, the term “cooling tower” means a cooling tower, evaporative condenser or fluid cooler that is part of a recirculated water system incorporated into a building’s cooling, industrial process, refrigeration, or energy production system. Most cooling towers are used for air conditioning and are shut down in the fall and opened again in the spring.
