[DOCKET NO. PHMSA-2013-0255 Amdt. Nos. 192-130 195-105 ] Document Number: 2022-07133 CFR: 49 CFR 192 49 CFR 195
The Pipeline and Hazardous Materials Safety Administration (PHMSA) has announced a new final rule that took effect on October 5, 2022. The rule includes several highlights specific to leak detection, such as the application to most Type A gas gathering, gas transmission, and hazardous liquid pipelines with diameters of 6 inches or greater. A small subset of rural gathering pipelines that cross bodies of water greater than 100 feet wide are also included.
Under the new rule, a rupture is defined as an “unanticipated or unplanned flow rate change of 10 percent or greater or a pressure loss of 10 percent or greater, occurring within a time interval of 15 minutes or less.” Relevant requirements include leveraging upstream/downstream pressure monitoring and effective leak detection systems, establishing written procedures for identifying and responding to a rupture, and responding to an identified rupture by closing Remote Mainline Valves (RMVs) to isolate the segment within 30 minutes.
However, gathering pipelines that connect terminals and processing facilities typically lack proper instrumentation such as SCADA and flow meters. That’s where Vanmok® Cloud technology comes in. Our technology provides a cost-effective solution for notification and identification of ruptures of 5% or greater within 15 minutes, relying solely on pressure transmitter data. This eliminates the need for SCADA and flow meters, making compliance with the new rule easier and more efficient.
*PHMSA initially suggested a 10 minute time limit but after receiving industry feedback, decided to exclude a time specification in the final rule

Find out how Vanmok Leak Detection helped a major USA pipeline operating company achieve regulatory compliance with the new PHMSA final rule for rupture detection on Short Lines.
This case study explores how Vanmok Leak Detection assisted a major USA pipeline operating company in achieving regulatory compliance with the new Pipeline and Hazardous Materials Safety Administration (PHMSA) final rule for rupture detection on Short Lines. The customer sought a leak detection solution that offered high sensitivity and reliability while minimizing costs. Vanmok’s cost-effective LD Cloud solution, which relies solely on pressure data, proved to be an ideal choice. By utilizing Vanmok Gateways connected to pressure transmitters and leveraging cloud-based technology, the system achieved leak detection sensitivity up to 1 m³/hr or 3% of the delivery flow rate. The solution surpassed API-1130 performance metrics, demonstrated reliability during abnormal operating conditions, and required no flowmeters or modifications to existing infrastructure. With fast implementation and scalability, Vanmok’s solution proved to be an efficient and compliant choice for the pipeline operating company.
