A strip club was evacuated and some commercial businesses were affected. The major threat was related to a possible entrance of the polluting substance in the city’s storm drains, which carry excess rain water into the Los Angeles River. It’s estimated there is no evidence for this but according to LAFD spokesman Erik Scott it was possible that the oil had seeped under manhole covers in the area. A LAFD team was at the scene to remove the crude oil which was flowing down the street. As calculated, 10,000 gallons (45,000 litres) had spilled, fortunately much less than was first originally estimated. The leak came from a pump station on one of its pipelines, the company Plains All American said in statement. More specifically, it was due to a faulty valve. Crude oil is a flammable mixture of hydrocarbons but in this case a fire was prevented.
