§ 8-03 Maintenance Program and Plan.
RCNY § 8-03
For each cooling tower system the owner must have a maintenance program and plan prepared by a qualified person in accordance with professional or industry bodies with expertise in cooling tower regulations and guidance, such as ANSI/ASHRAE 188, the manufacturer’s instructions, and the requirements of this Chapter. The plan must be retained and produced in accordance with subdivision (a) of 24 RCNY § 8-07. At a minimum, the plan must include and describe: (a) Management and maintenance team. Identification, including names and contact information (mail and email addresses and telephone numbers) and description of the function of each person on the cooling tower system management and maintenance team in a manner specified by the Department, including: (1) The owner of the building where each cooling tower system is located and any manager or other person designated by the owner as responsible for compliance with the requirements of Administrative Code § 17-194.1 and this Chapter.
(2)Any person designated by the owner as a responsible person, as defined in 24 RCNY § 8-02.
(3)Every consultant, service company and qualified person who cleans, disinfects, delivers chemicals or services the cooling tower system.
(b)Cooling tower system. Identification, specifications and description of each cooling tower system and all components located at a specific address, including: (1) The number of cooling towers in the cooling tower system.
(4)The purpose of the cooling tower system and seasonal or year-round operation including start and end date, if applicable. For systems with multiple cooling towers, conditional operation, such as cycling or scaling related to cooling demand, must also be noted.
(5)The New York City Department of Buildings registration number for each cooling tower.
(6)The cooling tower manufacturer, model number and serial number, if applicable.
(7)A flow diagram or schematic of the cooling tower system, identifying all of the principal components and appurtenances of the cooling tower system including makeup water and waste stream plumbing locations.
(c)Risk management assessment. The assessment must identify risk factors for Legionella proliferation and specify risk management procedures for all or parts of each cooling tower system, and anticipated conditions including: (1) Any dead legs or stagnant water in the recirculation system.

Where there is a conflict between the requirements of this Chapter, Part 4 of the State Sanitary Code, § 17-194.1 of the Administrative Code, and the manufacturer's instructions, the maintenance program and plan must reflect the most stringent requirement.
