LOS ANGELES (CNS) - Crews are continuing to clean up and repair an oil leak Wednesday in the Rancho Park area, and say it might take two or three days to complete.
The Hazmat crew working to clean up the leak told ABC 7 there is a lot of work ahead of them and the northbound lanes of Sepulveda Boulevard would be closed during the repairs. The southbound lanes were expected to open Tuesday night.
The exact source of a leak that caused as many as 1,000 gallons oil to seep through the ground in the Rancho Park area, prompting the closure of a heavily traveled stretch of Sepulveda Boulevard, has yet to be determined.
The seeping oil was first detected Monday night, with Los Angeles Fire Department crews responding just before 6 p.m. to the 2800 block of South Sepulveda Boulevard. Fire crews discovered oil bubbling out of the ground at a rate of about 3 to 5 gallons per minute, according to LAFD spokesman Nicholas Prange.
Prange said 500 to 1,000 gallons were believed to have seeped to the surface as of Monday night, and about 20 to 40 gallons escaped into a storm drain before crews were able to contain the leaking material.
Repair crews were brought in, but the oil continued seeping to the surface until around noon Tuesday, according to reports from the scene.
Multiple oil pipes run through the area and various agencies were working to determine which line was compromised. JoJo Comandante, a hazardous materials specialist with the Los Angeles County Fire Department, said the leak may have occurred simultaneously with a leak in a Los Angeles city water line. He noted that the oil managed to leak into a storm drain "unnoticed for 2 miles downstream."
Prange said officials requested a vacuum truck from the waste management company Clean Harbors and sand from the Los Angeles Bureau of Street Services to help mitigate environmental effects of the flow of the oil.
With the leak contained, there was no widespread public hazard, but crews were digging into the street to fully repair the damage.
Sepulveda Boulevard was closed between National and Exposition boulevards, and officials said the stretch could potentially remain blocked into Wednesday.
No injuries were reported and no evacuation orders were issued.
