Company: Leak at Pennsylvania gas storage well plugged

The operator of a natural gas storage well in Western Pennsylvania says workers have successfully plugged a leak that had been spewing massive amounts of planet-warming methane into the atmosphere for two weeks. 

Equitrans Midstream said the well at its Rager Mountain storage facility, located in a rural area about 1.5 hours east of Pittsburgh, was sealed shut with concrete on Sunday. The well had been venting about 100 million cubic feet of natural gas per day since Nov. 6, according to initial estimates. 

If accurate, that would total more than 1.4 billion cubic feet in methane, equal to the greenhouse gas emissions from burning more than 7,200 tanker trucks of gasoline. 

Pennsylvania environmental regulators have issued the company notice of five potential violations of state law.
