ANSI-GPTC G-192-11, found within the GPTC Guide for Gas Pipeline Systems, is the primary industry guide material for leak survey requirements. It is the document PHMSA and state regulators look to when evaluating an operator’s survey program. 

Picarro’s Advanced Mobile Leak Detection (AMLD) and Picarro Handheld leak detection integrated platform is a recognized surface gas detection survey method under G-192-11 Section 4.4. In this white paper we discuss how, with sub-ppb CRDS sensitivity and patented Field of View (FOV) technology, the Picarro solution not only aligns with the GPTC guidelines, it helps operators:

• Survey networks efficiently at traffic speed
• Document actual pipeline coverage—not just routes driven

• Make annual, full-network surveys operationally achievable
