Abstract:This report is in response to a Congressional mandate in the ; Accountable Pipeline Safety and Partnership Act of 1996 to survey ; and assess the effectiveness of remotely controlled valves (RCVs) ; on interstate natural gas pipelines and to determine their ; technical and economical feasibility to shut off gas after a ; rupture. ; This report contains a discussion of the results of a public ; meeting held in Houston, Texas on October 30, 1997 for the ; purpose of gathering information and discussing issues relevant ; to the survey and assessment. The report also contains the ; results of an RCV field evaluation conducted by Texas Eastern ; Transmission Corporation (TETCO) as part of a Consent Order ; issued by the Office of Pipeline Safety (OPS) (CPF 15102) to ; provide information on TETCO’s experience with RCVs. There is ; also a discussion of status briefings before the Technical ; Pipeline Safety Standards Committee (TPSSC) and a cost versus ; benefit study. ; The report addresses the four main issues raised by the ; Congressional mandate to study RCVs, i.e., effectiveness, ; technical feasibility, economic feasibility, and risk reduction. ; The report concludes with a proposal for further action, which is ; a public meeting to seek input on information for specifying the ; time-to-isolate a ruptured pipeline section.
