"Utility Steps Up Efforts To Plug Massive California Methane Leak"

"LOS ANGELES -- The head of Southern California Gas Co said it would take at least three more months to plug a massive underground leak of natural gas that has been seeping into the air since mid-October and now accounts for a quarter of the state's entire methane emissions.

The utility's president and chief executive officer, Dennis Arriola, also said on Tuesday the company would begin this week drilling a relief well designed to intersect the damaged pipeline hundreds of feet beneath the surface and inject it with fluids and cement.

The utility's latest strategy and time frame for addressing the stench of gas fumes that have sickened nearby residents for weeks and led to the temporary relocation of 200 families was laid out during a Los Angles City Council hearing."
