UPDATE: Natural Gas Tank Explosion

A Williams Northwest Pipeline natural gas tank is still in the process of being drained after an explosion last month.

A Williams spokesperson said shrapenal from the tank in Plymouth has been sent to labs across the country for further investigation to get a better understanding of what caused a vessel to rupture.

It could be another week or so before the tank is completely drained into the tank next to it.

It will be months before we have a more clear idea of what went wrong to cause the explosion that caused hundreds to evacuate their homes.
