Alameda County Fire: Crashed big rig carrying aluminum sulfate was not leaking

A big-rig hauling aluminum sulfate that crashed and ended up on its side Wednesday in Sunol is not leaking fluid, Alameda County fire officials said around 2:30 p.m

The 18-wheel double tanker was headed to the Sunol Water Treatment Plant and crashed while trying to navigate a tight turn just after noon at Felter and Calaveras roads.

The California Highway Patrol reported the big-rig was stuck in a gully, which fire officials said was difficult to access. There was concern that the tanker was leaking. However, the fluid turned out to be coolant from the vehicle.

No major injuries were reported and fire personnel said the driver was declining transport to a hospital. 

Roads in the area have been closed.
