Investigators are still trying to figure out what caused a storage tank to leak in Yakima River on Sunday.
The cause of the spill on Sunday from the tank at a former feed lot near Sunnyside, about 170 miles southeast of Seattle, was under investigation.
Department of Ecology spokeswoman Joye Redfield-Wilder said the oil posed a threat to otters, waterfowl and fish as well as orchards and other crops in the area.
"In a couple of weeks, the canals will all be full and (farmers) will be watering their crops and their orchards, so we want to get this cleaned up," Redfield-Wilder said.
