No structural damage has resulted from a fast moving grass fire that broke out at the U.S. Department of Energy’s Lawrence Livermore National Laboratory (LLNL) Site 300, an experimental testing facility located in San Joaquin county, about 15 miles east of the main lab site.

The fire consumed a total of 2,173 acres, mostly dry brush.

The flames were spread by high winds, which pushed the flames eastward onto private property adjoining Site 300. It eventually reached Interstate-580 west of Tracy.

No injuries nor damage to structures was reported.

The fire began around 4:30 p.m.

It apparently was caused when high winds shorted out overhead power lines.

Laboratory emergency personnel and mutual aid fire units from 40 engine companies responded.

They included Livermore-Pleasanton, Fremont, Alameda County, Camp Parks, Hayward, East Bay Regional Parks, Tracy, and Contra Costa county, under the command of the California Department of Forestry.

At the height of the fire, 160 firefighters were at the scene, along with six air tankers and two helicopters.

The fire was 90-percent contained by 8 p.m., and was fully contained about an hour later.

A much smaller grass fire burned about five acres at a different location on Site 300 a week earlier, but the two fires were completely unrelated.
