Michael Bromwich, who heads the agency that has replaced the Interior Department’s Minerals Management Service, will hold a series of public forums starting Wednesday in New Orleans. The meetings will explore the current system for drilling and workplace safety, oil and gas containment, and spill response. The eight hearings on the Gulf Coast and in Anchorage, he said, will determine “whether we can develop a level of comfort on all three issues that would enable the [interior] secretary to lift the moratorium in a principled way” before Nov. 30.
