The dataset contains the location, legionella sampling results and operational status of cooling towers operating in New York State. The data is self-reported by the cooling tower operator according to Public Health Law, Section 225(5)(a) Subpart 4-1 – Cooling Towers. This dataset is a weekly snapshot of the data collected from the NYS Cooling Tower Registry Website it does not contain historical data.

This dataset includes cooling tower regulatory inspection results from the NYC Health Department’s Office of Building Water Systems Oversight (BWSO).

The dataset includes results from two inspection types: cycle or non-cycle. Cycle inspections are regular compliance inspections conducted by BWSO to confirm adherence with cooling tower regulations. Non-cycle may include follow-up inspections or other regulatory inspections to evaluate public health risks.Cooling tower systems that are compliant at the time of inspection have the inspection date with blank values for the violation and citation columns. Building owners that are subject to financial penalties for a cited violation receive a notice of violation with a summons number, as shown in the dataset. The Office of Administrative Trial and Hearings (OATH) adjudicates the summons.

Hearing status and adjudication result are shown separately in the Cooling Tower Hearings dataset (a subset of the OATH Hearings Division Case Status dataset). The summons number in this dataset corresponds with the ticket number field in the Cooling Towers Hearings dataset.
