 +====== Aliso Canyon Methane (Natural Gas) Storage ======
  
 +=====Intro from Wikipedia====
 +
 +From WikiPedia: at [[https://​en.wikipedia.org/​wiki/​Aliso_Canyon_gas_leak |Aliso Canyon gas leak ]]
 +
 +The Aliso Canyon gas leak (also called Porter Ranch gas leak[1] and Porter Ranch gas blowout[2]) was a massive natural gas leak that was discovered by SoCalGas employees on October 23, 2015.[3] Gas was escaping from a well within the Aliso Canyon'​s underground storage facility in the Santa Susana Mountains near Porter Ranch, Los Angeles.[4] This second-largest gas storage facility of its kind in the United States belongs to the Southern California Gas Company, a subsidiary of Sempra Energy. On January 6, 2016, Governor Jerry Brown issued a state of emergency.[5] The Aliso gas leak's carbon footprint is said to be larger than the Deepwater Horizon leak in the Gulf of Mexico.[6] On February 11, 2016, the gas company reported that it had the leak under control.[7] On February 18, 2016, state officials announced that the leak was permanently plugged.
 +
 +An estimated 97,100 tonnes (95,600 long tons; 107,000 short tons) (0.000097 Gt) of methane and 7,300 tonnes (7,200 long tons; 8,000 short tons) of ethane were released into the atmosphere,​[8] The initial effect of the release increased the estimated 5.3 Gt of methane in the Earth'​s atmosphere by about 0.002%, diminishing to half that in 6-8 years.
 +
 +It was widely reported to have been the worst single natural gas leak in U.S. history in terms of its environmental impact.[9][10][11] By comparison, the entire rest of the South Coast Air Basin combined emits approximately 413,000 tonnes of methane and 23,000 tonnes of ethane annually.[12]

So do the number of lawsuits it's triggered, according to  Southern California Gas Company'​s third quarter report, released this week.The cost of the Aliso Canyon gas leak is up to $841 million as of Sept. 30. That’s up $9 million dollars over the last three months, the report said. One of the expenses stemming from the leak is an independent study to pinpoint why the well failed.

 +Nordella said different patients were exposed to different levels for different times, and it won’t be clear how people are affected unless researchers follow them for at least three to five years.

 +"A smart and successful natural gas storage program must include proper risk management and emergency response planning. That’s a lot of the secret sauce right there. These plans should outline the risks each facility faces, the practices and procedures for reducing those risks, and the playbook for dealing with problems. "
