New York City and New York State Cooling Tower Compliance 

New York City:


The City’s requirements are found in Local Law 77 of 2015. Local Law 77 requires registration, inspection, cleaning, disinfection, and testing of all Cooling Towers in NYC. Local Law 77 also requires building owners to annually certify that they are in compliance with the law. 

The New York City Department of Health and Mental Hygiene (DOHMH) also created new rules to implement Local Law 77. The new rules are Chapter 8 of Title 24 of the Rules of the City of New York. The rules require building owners to establish routine and long-term maintenance procedures for their cooling towers and for owners to register their towers with the City.
