ポーターランチで新たなガス漏れ 止めたと会社側

RT2016/7/7
A natural gas leak discovered near Porter Ranch in an Aliso Canyon storage facility has been quickly eliminated by SoCalGas. A similar leak last fall wasn’t contained until February and sent over 100 metric tons of natural gas into the atmosphere.

The new leak, according to the utility company, was discovered on Saturday during a routine inspection, forcing company personnel to perform necessary inspections.

The Southern California Gas Company (SoCalGas) determined that the leak came from a “buried three-inch-diameter pipeline not associated with the well’s operation,” the utility company's spokeswoman, Melissa Bailey, said in a statement.

“This was a very small leak and did not present a safety risk to SoCalGas employees or nearby communities,” she continued, adding that the leak was isolated by repairs made Sunday.

More than 4,400 households were displaced after the Porter Ranch natural gas leak was discovered in October 2015. The leak, over the next 16 weeks, vented an estimated 107,000 tons of methane, making it one of the worst leaks in US history. In February, state officials announced that the leaking natural gas well in Porter Ranch had been sealed.

In December, an anonymous video captured with an infrared camera surfaced online, showing a cloud of methane gas reigning over Porter Ranch.
