A top Interior Department official said the department is close to finishing a draft rule that toughens standards for subsea “blowout preventers,” the type of device that failed to halt BP’s runaway Gulf of Mexico oil well in 2010.

“We are near the completion of a proposed rule to enhance the reliability of blowout preventers based on studies of the Deepwater Horizon tragedy,” said Brian Salerno, director of Interior’s Bureau of Safety and Environmental Enforcement.

His comment is part of a broader speech delivered Tuesday at a regulatory conference in Australia.
