Emergency crews were called to the Mobile gas station on Route 303 in West Nyack around 7:30 a.m. today for a large fuel spill.
News 12 is told about 100 gallons of diesel spilled from a truck as it was filling an underground tank.
At least three separate fire departments responded along with the county hazmat team.
Hazmat crews had the spill cleaned up in less than an hour.
It does not appear any fuel ended up in a storm drain or a nearby creek.
The Rockland County Office of Emergency Management is now looking into what caused the spill.
