Damage Prevention
|
Outstanding . With the assistance of the Minerals Management Service, U.S. Coast Guard, and U.S. Army Corps of Engineers, develop and implement effective methods and requirements to bury, protect, inspect the burial depth of, and maintain all submerged pipelines in areas subject to damage by surface vessels and their operations. |
Open – acceptable response . Study completed in January 1998. Final rule published on August 10, 2004. On August 17, 2004, PHMSA submitted a letter requesting closure. NTSB responded by encouraging PHMSA to conduct further studies on risks associated with offshore areas. OPS is evaluating other options. |
Complete additional evaluation. |

Plastic Pipe
|
Outstanding . Determine the extent of the susceptibility to premature brittle-like cracking of older plastic piping that remains in use for gas service nationwide. |
Open – acceptable response . The Plastic Pipe Database Committee, with representatives from PHMSA, NTSB, American Gas Association, American Public Gas Association, Plastics Pipe Institute, Gas Research Institute, industry and the states, continue to collect data on in-service plastic piping material failures. Data collection will continue until January 2006. |

Fatigue Report
|
Fatigue
(Hours of Service)
|
Establish within 2 years scientifically based hours-of-service regulations that set limits on hours of service, provide predictable work and rest schedules, and consider circadian rhythms and human sleep and rest requirements. |
Open – acceptable response . PHMSA continues its assessment of human fatigue in pipeline operations in a variety of research and standards efforts. The study results are expected in June 2006. PHMSA published guidance in advisory bulletin ADB-05-06 (70 FR 46917; August 11, 2005). PHMSA is await NTSB feedback on P-98-30 and results of its study. |
Complete study and amend regulation, as necessary, based on study results. |

Pipeline Technology
(Excess Flow Valves) |
Require that excess flow valves be installed in all new and renewed gas service lines, regardless of a customer’s classification, when the operating conditions are compatible with readily available valves. |
Open – acceptable response . PHMSA is considering incorporating requirements for these valves in the upcoming integrity management rule for gas distribution pipeline. NTSB does not agree with that approach. Public meetings were held on June 17 and September 22, 2005, to discuss the use of these valves in gas distribution pipelines. The results of the meetings will be presented to the technical advisory committees at meetings scheduled for December 13 & 14, 2005. |
Amend regulations, as necessary. |

Pipeline Technology
(Internal Corrosion)
|
Revise regulations to require that new or replaced pipelines be designed and constructed with features to mitigate internal corrosion. |
Open – acceptable response . PHMSA is preparing an NPRM and expects to publish it in November 2005. |
Issue final rule. |

Pipeline
Intergrity
|
Remove the exemption in regulations that permits pipe to be placed in natural gas service after pressure testing when the pipe cannot be verified to have been transported in accordance with the American Petroleum Institute’s (API) recommended practice RP5L1. |
Open – acceptable response .
PHMSA plans to explore the technical feasibility of removing the exemption or other alternative action. This notice will also address recommendations P-04-02 and P-04-03.

Pipeline
Intergrity |
Evaluate the need for a truck transportation standard to prevent damage to pipe and, if needed, develop the standard and incorporate it into regulations for both natural gas and hazardous liquid line pipe. |
Open – acceptable response . PHMSA plans to explore the technical feasibility of removing the exemption or other alternative action. This notice will also address recommendations P-04-02 and P-04-03. |
