NEW ORLEANS — An expanse of Gulf Coast federal waters larger than the state of Colorado was unlawfully opened up for offshore drilling leases, according to a ruling by a federal judge, who said the Department of Interior did not adequately account for the offshore drilling leases’ impacts on planet-warming greenhouse gas emissions and an endangered whale species.
The future of one of the most recent offshore drilling lease sales authorized under the Biden administration is in jeopardy after District Court for the District of Columbia Judge Amit Mehta’s finding on Thursday that the federal agency violated bedrock environmental regulations when it allowed bidding on 109,375 square miles (283,280 square kilometers) of Gulf Coast waters.
Environmental groups, the federal government and the oil and gas industry are now discussing remedies. Earth Justice Attorney George Torgun, representing the plaintiffs, said one outcome on the table is invalidating the sale of leases worth $250 million across 2,500 square miles (6,475 square kilometers) of Gulf federal waters successfully bid on by companies.
The leases in the Gulf Coast were expected to produce up to 1.1 billion barrels of oil and more than 4 trillion cubic feet (113 billion cubic meters) of natural gas over 50 years, according to a government analysis. Burning that oil would increase carbon dioxide emissions by tens of millions of tons, the analysis found.
The agency “failed to take a ‘hard look’” at the full extent of the carbon footprint of expanding drilling in the Gulf Coast, the judge wrote.
The auction was one of three offshore oil and gas lease sales mandated as part of a 2022 climate bill compromise designed to ensure support from now-retired Sen. Joe Manchin, a leading recipient of oil and gas industry donations. Another of the mandated oil and gas lease sales, in Alaska’s Cook Inlet, was overturned by a federal judge last July on similar grounds.
“If federal officials are going to continue greenlighting offshore drilling, the least they can do is fully analyze its harms,” said Hallie Templeton, legal director at Friends of the Earth, a nonprofit that is of the plaintiffs in the lawsuit. “We will keep fighting to put a full stop to this destructive industry, and in the meantime, we will keep a close watch on the government to ensure compliance with all applicable laws and mandates.”
The drilling would also threaten the Rice’s whale, a species with less than 100 individuals estimated to remain and which lives exclusively in the Gulf Coast, according to court records filed by environmental advocacy groups.
A Department of the Interior spokesperson said the agency could not comment on pending litigation.
The process did not meet the standards of the National Environmental Policy Act, or NEPA, which requires federal agencies analyzes the environmental impacts of their actions prior to decision-making around federal lands.
While Joe Biden later sought to ban offshore drilling in his last days in office, President Donald Trump’s administration has pushed a “drill, baby, drill” agenda expanding the fossil fuel industry, withdrawing the U.S. from the Paris climate agreement and rolling back environmental regulations — including for NEPA.
The American Petroleum Institute, or API, an oil and gas trade association representing more than 600 firms and a party to the Gulf Coast case, said it is evaluating its options after this week’s ruling.
API spokesperson Scott Lauermann said the case is an example of activists “weaponizing” a permitting process, “underscoring how permitting reform is essential to ensuring access to affordable, reliable energy.”
Chevron, a defendant in the lawsuit, declined to comment and referred The Associated Press to the API’s statement.
Three offshore oil and gas lease sales are scheduled over the course of the next five years.
