Anybody hear about the rail car leaking styrene in Cincinnati?

"A tanker continues leaking styrene gas into the air near Lunken Airport and crews aren't sure when the situation will be resolved."

Full story here

Seems like a little overreaction to me.. but then again, I haven't been to the scene, nor do I know how much it is leaking.
At last check, they've had 4 unmanned Monitors on the railcar all day trying to cool it off, I guess.
