Managing the Nation's Cast Iron Inventory
The AGA Board of Directors has designated Pipeline Safety as the number one priority of its member companies. It encompasses the repair, replacement and reconditioning of pipelines and related facilities and is a primary focus of natural gas utilities as they maintain safe and reliable operations. In Section 7 of the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011, Congress directed the Secretary of Transportation to develop a report on the national cast iron inventory and the progress being made by owners and operators in implementing management and replacement plans for that inventory. This paper creates a foundation for framing the discussion of cast iron main in natural gas distribution systems nationwide.
