FERC Approves Second of Three Oregon LNG/Pipeline Projects

PHMSA Announces Final Control Room Management Rule, Controversial Elements Dumped From DIMP
February 2010 Vol. 65 No. 2

A separate annual report on failure of compression couplings resulting in only hazardous leaks is also required. The first report is due March 15, 2011. This information must include, at a minimum, location of the failure in the system, nominal pipe size, material type, nature of failure including any contribution of local pipeline environment, coupling manufacturer, lot number and date of manufacture, and other information that can be found in markings on the failed coupling.

While PHMSA ditched the controversial human resources component in the IM plan, as distribution companies requested, it did not grant another request: that it reclassify low stress pipelines now classified as gas transmission lines – and thus under the much more onerous interstate IM program – as distribution lines if they operate below 30 percent specified minimum yield strength (SMYS). Laclede Gas Co., the major gas utility in Missouri, had said it was costing it $10,000 a mile to assess the 134 miles of its low stress pipelines running through high consequence areas. Of those 134 miles, 84 percent operate below 30 percent SMYS. The final rule says PHMSA may consider this change later but that additional research is required to support such a change.
