They did issue an "all clear" so I turned on my air conditioning and now I don't care if I go outside or not. LOL

It was the Marathon Galveston Bay Refinery and the warning was issued because of a unit disruption that "caused a heavy smell of sulfur to fill the air." I also heard that everyone was accounted for and there were no injuries.

I did hear a lot of helicopters and sirens, which could have been related just as a precaution, but I'm glad there are no injuries.
