PHMSA Issues Advisory on Cast-Iron System Repairs
Date:2013-11-14
Accelerated repair of more "leak-prone" natural gas distribution system components is an issue of focus for PHMSA - the Pipeline and Hazardous Materials Safety Administration (PHMSA) of the U.S. Department of Transportation. On March 23, PHMSA published in the Federal Register an advisory bulletin to owners and operators of natural gas cast iron distribution pipelines and state pipeline safety representatives - highlighting "the need for continued safety improvements to aging gas pipeline systems."
This advisory bulletin, among other points, urges owners and operators to conduct a comprehensive review of their cast iron distribution pipelines and replacement programs; and accelerate pipeline repair, rehabilitation and replacement of high-risk pipelines. It also requests state agencies to consider enhancements to cast iron replacement plans and programs.
