The shelter-in-place was given as a precaution to those living in Texas City after a leak was discovered at the Marathon refinery on 10th St.
It was described by emergency officials as a pinhole leak and a small amount of hydrofluoric acid may have been escaping
Those living east of 21st St. had to spend a couple hours indoors. By early evening, they were able to go back outside.
"They call you from Texas City and tell you to stay in the house and shut the doors. That's all you do. It happens pretty regular," resident Matt Azzano said. "I work at BP and it seems like this happens all the time, so I don't get concerned."
Resident Joseph Toney had a similar attitude.
"At least times a month there will be a chemical spill it seems like, here recently," Toney said. "It's real alarming to all our kids and it's kind of a hassle. I mean, just like spring break. All of our kids, they play in these areas."
The cause of the leak was not known late Sunday.
We contacted Marathon about the leak and the company gave us the following statement: "The source of the release has been located, and crews are working on isolating it. There has been no off-site impact."
