AUSTIN (KXAN) — The Austin Fire Department said it can’t determine what caused a second fire at an illegal dumping site in southeast Austin.

But it said investigators could not rule out Sunday’s fire on Brandt Road was either intentionally set or a hotspot from the July 22 fire.

AFD said while the fire is under control, it will have crews monitor the fire overnight. The column of smoke from the 2100 block of Brandt Road, east of Interstate 35 but west of East Slaughter Lane, could be seen from miles away. Viewer Christa Wilke sent us these photos before crews had it knocked down.

It was the same area AFD and others responded to July 22, AFD said.

A STAR Flight helicopter helped get Sunday’s fire under control with water drops. Travis County ESD Nos. 5 and 11 also responded to the fire.

AFD said a U.S. Forest Service Strike Team helped with a bulldozer to cut a fire line around the burned area.

With another triple-digit temperature day in Central Texas, AFD said some of the firefighters were being treated by medics for heat exhaustion.

AFD said Austin-Travis County EMS paramedics took one firefighter to the hospital Sunday due to a heat injury.
