Smoke spreading from a large hay facility fire in Yolo County drifted into the Livermore Valley Friday, causing discomfort for some but no health threatening issues.
By last night, the skies were clear as firefighters at the hay storage facility near Winters kept the fire from spreading and gradually extinguished the blaze.
People from Pleasanton to Santa Cruz have been complaining all day about an odor that's spreading though the region, but officials say there's no cause for alarm.
The culprit, according to Jim Miguel, Livermore-Pleasanton Fire Department Chief, is a large fire burning in Yolo County.
"They have a large hay facility that's on fire up there," said Jim Miguel, Livermore-Pleasanton Fire Department Chief. "It's been on fire since (Thursday) night and its likely to smolder for days if not weeks. There are tons of hay up there," Miguel said.
He said the LPFD started getting calls early Friday morning.
Miguel said there's little danger to Livermore Valley residents.
"If people have respiratory disorders, they may want to stay inside and turn on their air conditioners, but there's no particular danger from the smell," he said.
The fire is at Hay Kingdom, a hay exporting company, about 10 miles north of Vacaville, on the Yolo and Solano County line. Officials say it will continue sending plumes of smoke into the air for the next several days.
The pungent smoke could be seen in Fairfield and as far away as eastern Contra Costa County.
Mark Persons, a spokesman for the Yolo County Sheriff's Department said the cause is still undetermined.
He said the value of the 10 acres of hay that has burned so far is estimated at $2 million.
According to Persons, the fire started around 10 p.m. Thursday.
