Oil & Gas Journal: US Sen. Edward J. Markey (D-Mass.) introduced a bill on Apr. 8 that would require the use of professional engineers to approve local natural gas delivery system changes and on-site monitoring of pressure regulation stations so that qualified employees could quickly shut off gas flow in an emergency. Rep. Lori Trahan (D-Mass.) introduced a similar measure, HR 2139, in the US House the same day.
The bills were responses to explosions resulting from over-pressurization of Columbia Gas of Massachusetts pipes, which were being replaced in the Merrimack Valley near Boston on Sept. 13, 2018.
