As a result of ABC 7's reporting, regulators and elected officials will conduct two separate investigations in Maryland and Virginia into whether Washington Gas neglects gas leaks.
Two Maryland Delegates -- Melony Griffith and Derek Davis -- this week revealed plans for their own investigation.
The Virginia State Corporation Commission has indicated previously it would investigate.
Virginia State Senator Mark Herring also wrote a letter to the Commission.
"I will make sure that regulators take [these concerns] seriously," he told ABC 7 via phone. "The public has a right to know that regulators are going toget to the bottom of this."
Carl Weimer, the director of the Pipeline Safety Trust, a national advocacy group, added: "Interestingly, we have been increasingly contacted by ex-employees in other areas of the country (New England, Texas, California) with similar claims of downgrading of leaks and reprisals against employees who try to question the downgrading. Really makes me wonder if the story you have written is the tip of a much larger iceberg."
