MILPITAS -- Crews worked Wednesday night to snuff out a hard-to-reach fire that broke out in 20-foot-high piles of debris inside a large warehouse at the Newby Island Landfill, according to fire officials.

The fire was reported around 7:15 p.m. at the site at 1601 Dixon Landing Road, and went to two alarms shortly before 8 p.m.

"Basically, we got a dump facility where they have a lot of piles inside a metal-clad building," said Capt. Rob Brown of the San Jose Fire Department, which is handling the bulk of the operation. "One of those piles started smoldering, and it's being stubborn."

He described the site as a six-bay transfer facility, about 150 feet wide. He said crews from the facility were using equipment to move some of the debris so firefighters could better access the burning pile.

Brown said it is expected to be an extended operation. Milpitas crews are assisting.
