In Porter Ranch, residents are reporting a range of symptoms related to the gas leak. Some with bloody noses and headaches; others with nothing -- even within the same family. Resident Patrick Perez shares how his family has been affected.
Our family is divided. My wife thinks that her health and my kids’ health has been adversely affected. I spend time away at work and I have not been feeling anything.

The government agency that regulates Southern California's air quality sued Southern California Gas Co. on Tuesday, accusing the company of negligence in a massive gas well leak that has forced thousands to leave their homes.
The South Coast Air Quality Management District said the utility's negligence extended to the design, construction, operation and inspection of one of the wells at the Aliso Canyon Natural Gas Storage Facility near Porter Ranch, according to the civil complaint filed in Los Angeles County Superior Court.
On Saturday, regulators approved a comprehensive abatement order that requires the Southern California Gas Co. to take immediate steps to contain the leak affecting Porter Ranch, permanently shut down the damaged well, establish a leak-detection system and conduct an independent health study.
Many of the hundreds of residents and activists who attended Saturday’s hearing expressed disappointment over the order, saying it fell short of calling for the gas company to shut down all of its wells on the site.
There should be no other choice but to shut down the dangerous Aliso Canyon facility and look to close every urban oil and gas facility throughout California and our country, to ensure the health of our communities and our climate is never again sacrificed for corporate polluter profits.
Southern California Gas Co. said Monday, Jan. 18 that it has abandoned a plan to capture and burn the leaking natural gas that has forced thousands of Porter Ranch residents to relocate, citing safety concerns.
The company made the decision after consulting with state agencies, including the South Coast Air Quality Management District, before concluding that none of the designs could provide “the safety level that SoCalGas believes is required.”
The state Public Utilities Commission had given the gas company a Jan. 19 deadline to address concerns about capturing and burning the gas, noting that the design calls for blowers with electric motors that could spark an explosion.
State senators made the case on Monday to shut older natural gas wells at Aliso Canyon until officials and an outside agency can verify that they do not pose a risk to public health.
