Inspecting & Disinfecting Cooling Towers
The Department of Health and Mental Hygiene (DOHMH) Commissioner’s order requires building owners to hire environmental consultants with demonstrated experience performing disinfection using current industry standard protocols including the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE), Standard 188P, and Cooling Technology Institute Guidelines WTB-148.
Disinfection requires the use of biocides, which requires commercial pesticide applicator certification in Category 7G – Cooling Towers, Pulp & Paper Process issued by the NYS Department of Environmental Conservation (NYS DEC).Current information on all registered pesticide businesses in Category 7G (Cooling Towers)
can be found on the New York State Department of Environmental Conservation (NYS DEC)
web site through the Pesticide Business/Agency icon
. Options to narrow search include by category (7G- Cooling Towers) and by location (Region 2 for New York City).
If an evaluation or test indicates microbial levels signifying a maintenance deficiency that requires mitigation, building owners are responsible for notifying DOHMH, cleaning and disinfecting the tower in accordance with Local Law 77 of 2015
