The refinery is in the 3700 block of West 190th Street.

KCAL9’s Peter Daut reported from the scene.

Police say the burn-off is producing a large amount of heat, and they’re also concerned about the smoke not dissipating because of the thick marine layer.

The flares, some on social media called them fireballs, were first spotted around 6 p.m

The spectacle stirred up residents already on edge after a massive  explosion at the refinery in February 2015. During that incident, residents had to deal with ash, concerns over poor air quality and a surge in gas prices.
