  •  Is that a good or bad response time? (1+ / 0-)

    Serious question.

    This is an old pipeline, after you shut of pressure downstream (however far that is) how long is it before all the oil that's going to flow out of the pipeline does so?

    Was the shut-off remote controlled, or did someone have to go out there and turn a valve?  It's buried, so presumably there's only a couple of access points.

      the streets of Mayflower. Another witness said it was more like 90 minutes. Stories vary of course. Most witnesses are not scientists with stop watches.

      •  Regarding response time, here's an example (2+ / 0-)

        [Enbridge's] emergency response plan the company keeps on file with PHMSA [Pipeline and Hazardous Materials Safety Administration (a perennially underfunded and understaffed division of the US Department of Transportation)] is more specific. It says a rupture on the Lakehead system would be detected within five minutes and the damaged segment closed in three minutes.

        I am assuming that ExxonMobile or any other such company would have a similar emergency response plan filed. Here's their website on emergency response.

        They claim their personnel "were on the ground within 30 minutes after the leak was detected." Witnesses on the ground have different stories. It will be confirmed in court since there is a class action law suit pending against the company. They have till April 10 to produce "investigative reports, inspection documents and other information connected to the incident."
