FILE - This Sept. 28, 2010 file photo shows Pipeline and Hazardous Materials Safety Administration Administrator Cynthia L. Quarterman testifying on Capitol Hill in Washington. Senators say they’re frustrated with the government’s slow pace at writing new rail safety regulations in light of recent fiery freight train accidents and a deadly commuter train derailment. Sen. Richard Blumenthal, D-Conn., warned witnesses at a Senate hearing Thursday, “one of the things we're going to do here is impose accountability.” Quarterman said her agency is working as fast as possible drafting new standards for rail tank cars used to transport crude oil, but it takes time to address the more than 100,000 public comments the agency has received.
