RALEIGH, N.C. (WNCN) – Raleigh police and fire crews responded to a diesel leak from a generator on South Wilmington Street, near the Duke Energy building Sunday morning.

The leak was reported around 9:30 a.m. by someone working inside the building.

Authorities said later Sunday that between 3,000 and 3,500 gallons of diesel spilled when a fuel line leaked.

Hazmat, firefighters and Prime Power crews contained the leak and are working to determine how much fuel spread.

Authorities say there is no threat to the public.

The diesel fuel leaked into the storm water system and crews are working to get it cleaned up.
