A malfunctioning vehicle was leaking burning matter from its exhaust pipe, triggering three separate blazes that eventually merged into one about 5 p.m. Friday in the area of Apple Tree Lane and Oak Glen Road.
“The determination is reinforced by multiple independent witnesses, as well as supporting physical evidence,'' according to a Riverside County Fire Department statement. “Officers are seeking information from anyone who may have seen a vehicle which appeared to have mechanical problems, or unusual smoke emitting from it. If you were driving on Oak Glen Road at the time the fires were small, Cal Fire peace officers want to talk to you.''
Anyone with information was urged to call the Cal Fire hotline at 800-633-2836. Callers may remain anonymous.
There had been unverified reports of a man walking along the roadway, igniting fires amid dry and brittle conditions and triple-digit heat, but Cal Fire debunked those rumors and said black soot belching from a diesel exhaust pipe sparked the fire.
“Diesel vehicles shoot out that black soot,'' Cal Fire Capt. Fernando Herrera told the Press Enterprise. ``When that is shooting out, it does form some small particles, they can be from a pebble size, even up to a quarter size. And as those are emitted through the exhaust they are extremely hot, so when they land on any type of dry fuel, it will ignite.''
The head of the Apple Fire is on a mountainside in San Bernardino County, according to the U.S. Forest Service. Two Cal Fire air tankers and 12 water-dropping helicopters were working to establish containment boundaries, as more than 2,500 personnel on the ground gradually attempted to encircle the brusher. As the fire burns into the wilderness, vegetation is becoming sparse, helping to limit the fire’s intensity.
Gov. Gavin Newsom announced the state will receive a Fire Management Assistance Grant from the Federal Emergency Management Agency to help ensure resources will be available to fight the brush fire. The grant will also allow local, state and tribal agencies responding to the fire to apply for 75% reimbursement of their eligible costs, the governor said.
