In response to an inquiry by the National Commission on the BP Oil Spill and Offshore Drilling, Michael Bromwich, head of the new Bureau of Ocean Energy Management, Regulation and Enforcement, explained that there is a possibility that the moratorium on deepwater drilling could be lifted before November 30, 2010, for “certain categories of rigs.” As the Houston Chronicle reports, such rigs may include those that “present fewer risks than others and are sufficiently safe.” No specific details were provided on which rigs would fall under these categories.
