N.Y. Comp. Codes R. & Regs. tit. 16, § 420.11 – Leaks.

(a) Any notification of a steam leak, or any notification of damage to facilities by contractors or other outside sources shall constitute the need for prompt action.
(b) Each steam corporation shall be responsible for the investigation, prioritization, and repair of each leak found on its system.
(c) Emergency leaks require an immediate response to protect life and property and must be worked continuously until repairs are completed or until the condition is no longer hazardous. Emergency leaks include, but are not limited to:
1. (1) any leak on the bellows of an expansion joint;
2. (2) any leak which could cause property damage or personal injury or any leak which, in the judgment of the operating personnel at the scene, is regarded as potentially hazardous; or
3. (3) any leak resulting from damage by contractors or other outside forces.
(d) Nonemergency leaks include any leak which is not immediately hazardous at the time of discovery and can be reasonably expected to remain that way. Nonemergency leaks shall be repaired within six months from the date of discovery.
(e) A steam leak record, identified by number shall be used to depict the entire history of a leak from the time of discovery through repair. The record shall contain information as to the nature of the repair.
