Just two weeks after the nine-year anniversary of the BP Deepwater Horizon disaster—the largest ocean oil spill in U.S. history—the Trump administration on Thursday moved to dismantle offshore drilling regulations aimed at preventing another catastrophic leak.

The White House’s revised Well Control Rule—which could save the fossil fuel industry close to a billion dollars over the next decade—was unveiled by Interior Secretary David Bernhardt, a former oil lobbyist who advocacy groups have described as a “walking, talking conflict of interest.”

Diane Hoskins, campaign director at Oceana, called the Trump administration’s move “a major step backward in offshore drilling safety.”

“Gutting the few offshore drilling safeguards established in wake of the BP Deepwater Horizon disaster is reckless and wrong,” Hoskins said in a statement. “More drilling and less safety is a recipe for disaster. We should be implementing new safety reforms, not rolling back the few safety measures currently in place.”

The Trump administration today weakened crucial offshore drilling safety standards that were put in place after the 2010 BP Deepwater Horizon oil disaster, which killed 11 people and covered the seas with millions of barrels of oil. https://t.co/y9MY87Vuuk
