I figured this was breaking news, as they are surely talking about it around here, but since it wasn't proceeded by a big explosion, it's not really making much news.
Right now they aren't sure where it's coming from. This is literally miles from where I'm typing this right now.

Edit: A texas based company has claimed responsibility for the leak while capping a well. The well is now capped and the source of the leak has been closed.
