NYC Cooling Tower Regulations

     The City of New York recently passed Local Law 77 of 2015 which requires owners and operators of cooling towers to take certain actions.  Since the announcement, there has been some confusion on the specific mandates that have been established by NYC, so here are the main points you need to know:


Inspection & Testing:
  • Towers are to be inspected every 3 months while in use.
  • Cooling Towers that have been shut down for more than 5 days must be cleaned and disinfected within 15 days before intial use.
  • Water Treatment alone does not satisfy these NYC Requirements.

Annual Certification:
  • The owner or operator of a cooling tower must file certification each year that the tower has been inspected, tested, cleaned, and disinfected in compliance with section 17-194.1 of the administrative code.
  • Such certification shall be submitted by November 1, 2016 and each year thereafter.

What Paperwork Do I Need To Retain?:
  • Upon completion of services, you will be provided with a receipt and description of services.
  • Paperwork must be kept on site for at least six years.
