Between 800 and 1000 gallons of gasoline spilled into the drain after it leaked from a gas station at Glenarm and Arroyo in the City of Pasadena at around 5 p.m. on Sunday.

The gas spill was reportedly the result of a pump at the gas station being struck by a car, and the emergency shutoff on the gasoline pumps malfunctioning, reported KABC.

The storm drain empties into the Alhambra wash and enters into the City of San Marino at Monterey Road and Mission Street. All residents bordering the wash have been advised to stay indoors with windows closed. Residents can expect a gasoline odor coming from the wash.

Speaking to KTLA, Raymond Rindone, a San Marino resident, said the “annoying” smell coming from the spill is “everywhere.”

“It’s literally like smelling gas out of a gas can, like nonstop,” Rindone said.

The average price for a gallon of gas in California is around $4.67, meaning more than $3,700 worth of gasoline was lost in the spill.

The City of Alhambra posted photos of the gasoline in the drain on social media while advising those along the wash to stay indoors.

The City of San Marino said the Los Angeles County Health Hazardous Materials Division is on-site conducting evaluations of the situation.

A clean-up process is set to take place over the next several hours.

The City of San Marino also tweeted out a map of the affected area.

In a statement, the San Marino Police Department said: “Approximately several hundred gallons of gasoline spilled into the Alhambra wash and is traveling south towards San Marino.

“As a result, there is a smell of gasoline on the west side of San Marino coming from the Alhambra wash. San Marino Fire and San Marino Police are aware of the situation and request that residents stay inside with all doors and windows closed.

“If anybody is experiencing severe illness, call 9-1-1. The duration of this incident is expected to last approximately six hours.”

There have been no reports of any injuries so far as a result of the spill.

“There is no current threat to the public,” Pasadena Fire Department spokesperson Lisa Derderian told The Los Angeles Times.

The Los Angeles County Department of Public Works is handling all runoff outside the city, Derderian said.

Newsweek has contacted the City of Pasadena for an update on the clean-up operation.
