In response to the 2015 outbreak of Legionnaires' Disease that was attributed to cooling towers, the City requires all building owners to register, maintain, and test their cooling towers, fluid coolers, and evaporative condensers.
Building owners and property managers are required to register cooling towers, fluid coolers and evaporative condensers with the City. If you own or manage cooling towers, fluid coolers, or evaporative condensers, you must register them through Cooling Tower Web Portal.
In addition to initial registration, building owners must file an Annual Certification each year attesting that all cooling equipment was inspected, tested, cleaned and disinfected in accordance with the Maintenance Program and Plan (MPP). The certification must document any lapses in compliance with the MPP, as well as the corrective actions taken to address the deficiencies. Registered users can upload their annual certifications to the Cooling Tower Web Portal.
Failure to register or upload an Annual Certification may result in a fine issued by the Department of Buildings.
Building owners and property managers must follow the cooling tower maintenance and testing regulations — Chapter 8 of the Rules of the City of New York (PDF), in compliance with Local Law 77 of 2015 (PDF).
As a building owner, you must retain a qualified person to develop and implement a Maintenance Program and Plan (MPP) for your cooling tower system. The MPP describes procedures for describing monitoring, cleaning, disinfection, and all other activities taken to prevent and control Legionella growth.
Building owners are required to ensure cooling tower maintenance and management activities are conducted appropriately. You must log and maintain all records regarding cooling tower system:
The City conducts yearly inspections of cooling tower systems, Maintenance Program and Plans, and operational records. You can look up inspection results of cooling tower systems by building address or building identification number (BIN).

If an inspection finds potential violations, building owners may receive summonses subject to fines.
