A ruptured gas line poured about 100 gallons of gasoline into Newport Harbor on Sunday, authorities said.
The 3:30 p.m. incident occurred at the dockside Texaco gas station near the Balboa Island Ferry on the 500 block of East Edgewater Avenue, Newport Beach Fire Battalion Chief Don Jones said.
Firefighters placed a boom around a 100-by-200-foot area in the harbor, Jones said. The ruptured line, equipped with a spill sensor, was shut off automatically, he said.
Jones said the line appeared to be frayed from normal use, but an investigation will be conducted.
"It's not a real significant fire hazard, but it is an environmental hazard," Jones said.
Officials from the U.S. Coast Guard, Orange County Environmental Management Agency and California Department of Fish and Game were notified of the spill.
