Oil spilled from a tank farm at Signal Hill in Los Angeles, California on 23 October following a pumping fault.
The oil entered a public neighbourhood and was seen flowing down streets, resulting in a shutdown of roads and a major intersection. Police urged drivers to steer clear of the area.
According to Los Angeles County Fire Inspector Quvondo Johnson, some oil did flow into the storm drain system, although the exact volume is not yet known. The storm drain empties into local waterways and authorities from the California Department of Fish and Game and the US Coast Guard responded to the leak for fear of contamination.
Los Angeles County Health and Hazmat crews were also called the incident, which was reported just before 8am.
The spill was caused when a high pressure line pumping crude oil into a tank backed up and overflowed.
The oil was contained within 30 minutes, with clean-up expected to take around one day. Johnson said the spill is 'static' and 'under control', with the team now 'working on clean-up'.
It is now up to state authorities to determine whether the tank farm should be fined.
