WASHINGTON (AP) — The federal agency that regulates pipelines has announced new rules aimed at reducing leaks of methane, a potent greenhouse gas, from a network of nearly 3 million miles of natural gas pipelines that crisscross the country. The proposal Friday by the Transportation Department’s Pipeline and Hazardous Materials Safety Administration would significantly improve the detection and repair of leaks from gas pipelines, keep more product in the pipes and prevent dangerous accidents, officials said.
