AGA developed this webpage to compile information available on MAOP record verification and testing. The information presented has been developed by AGA, government entities, and other pipeline safety stakeholders. The information is already in the public domain. AGA assertively supported the MAOP verification and testing provisions in the Pipeline Safety Act of 2011. The gas transmission pipeline structure is very complex. The diversity of the transmission pipe is so complex that no single process will provide solutions for every pipeline operator. The information on the webpage will help operators develop pipeline testing and replacement plans and aid regulators in reviewing rate cases to support implementation.
