The BAAQMD says the Oct. 15 fire sent high levels of smoke particles into the air, but county health officials say smoke did not contain unusually high levels of toxins.

"During this event, I got a lot of emails from the board (asking), 'Why aren't you out there?'" CEO Jack Broadbent said. "We were too busy trying to communicate to the public and try to coordinate our activities to really explain roles and things like that."
The BAAQMD's announcement comes at the same time that ABC7 News learned the NuStar Energy Plant resumed partial operations following the fire in Crockett.
The cause of the mid-October fire is still not yet known.
