Narrative
On 10/3/11, the torrance refinery experienced a pinhole leak near the torrance meter station for the 8" truck unload relief pipeline. The leak resulted in a 41 bbl loss of primary containment of which all was contained within the confines and property of the exxonmobil refinery. This is a relief pipeline that protects exxonmobil pipeline company commodity pipelines which are upstream from the torrance meter station. This section of relief piping runs from the meter station to the 2 designated breakout tanks inside the refinery. As a result of the leak, the relief piping and exxonmobil pipeline commodity pipelines were immediately taken out of service. There was not a pressure surge incident, but rather, a pinhole leak had developed on the external relief piping that resulted in a loss of containment. Note: the ca state fire marshal's office of pipeline safety is aware of this incident and a csfm representative visited the site to review post incident, and reviewed the required hydrotesting that was conducted as part of recommissioning of the relief pipeline. Part e5f update was made 1/21/14 by thad massengale, exxonmobil pipeline co.
