On Oct. 23, Southern California Gas technicians discovered a leak of methane from a failed casing on one of the pipes in its Alisa Canyon storage facility, about 30 miles northwest of Los Angeles.
The company estimates it will be the end of March until it can plug that leak from the pipe that is about 9,000 feet deep.
About 77,000 tons of methane, a greenhouse gas that can widen the ozone hole in the atmosphere, have already gone into the air.
Residents in the area have complained of nausea, dizziness, headaches and nosebleeds from the sulfur-like odor that is put into natural gas to identify it.
Residents of about 3,000 households have been relocated. Hundreds are now living in hotel rooms, and will be there for at least two more months.
The L.A. Unified School District closed two schools until March 2016 . . .
The Federal Aviation Administration banned flights under 2,000 feet from going within a half-mile of the leak.
Gov. Jerry Brown has declared an emergency state for the area.
It is the worst methane leak in U.S. history, amounting to about 15 percent of all hourly greenhouse gas emissions in the U.S.
A reminder: The leak began almost three months ago.
