Section 195.444 - Leak detection(a)Scope. Except for offshore gathering and regulated rural gathering pipelines, this section applies to all hazardous liquid pipelines transporting liquid in single phase (without gas in the liquid).(b)General. A pipeline must have an effective system for detecting leaks in accordance with §§ 195.134 or 195.452 , as appropriate. An operator must evaluate the capability of its leak detection system to protect the public, property, and the environment and modify it as necessary to do so. At a minimum, an operator's evaluation must consider the following factors-length and size of the pipeline, type of product carried, the swiftness of leak detection, location of nearest response personnel, and leak history.(c)CPM leak detection systems. Each computational pipeline monitoring (CPM) leak detection system installed on a hazardous liquid pipeline must comply with API RP 1130 (incorporated by reference, see § 195.3 ) in operating, maintaining, testing, record keeping, and dispatcher training of the system.Amdt. 195-102, 84 FR 52296 , Oct. 1, 2019
