The federal government is withdrawing a proposal that would require more ships to slow down in East Coast waters to try to save a vanishing species of whale, officials said Wednesday.

The move in the waning days of the Biden administration will leave the endangered North Atlantic right whale vulnerable to extinction as the Trump administration is signaling a shift from environmental conservation to support for marine industries, conservation groups said. But federal authorities said there’s no way to implement the rules before President-elect Donald Trump takes office Monday.

The new vessel speed rules proposed by the National Marine Fisheries Service more than two years ago have been the topic of much debate among shippers, commercial fishermen and wildlife conservationists, all of whom have a stake in the whale’s fate.

The whale — which is vulnerable to collisions with ships — numbers fewer than 380, and its population has plummeted in recent years, though the most recent annual population estimate found the number of whales increased slightly in 2023.

The Trump administration is likely to be less enthusiastic about new restrictions on shipping, said Gib Brogan, a campaign director with conservation group Oceana.

“While we’ve been waiting and watching the proposed rule move forward, and ultimately stall, we’ve watched on-the-water outcomes of the current insufficient protections,” Brogan said. “And we’ve watched whales be killed by speeding boats.”

THOUSANDS OF PUBLIC COMMENTS

The proposed rules would have expanded slow zones off the East Coast as well as the size and classes of boats and ships that must slow down.

The fisheries service received about 90,000 public comments about them, according to documents set to be published in the Federal Register on Thursday. The filing says the service “does not have sufficient time to finalize this regulation in this administration due to the scope and volume of public comments.”

The final rule to modify North Atlantic right whale vessel speed regulations had been with the White House Office of Information and Regulatory Affairs, which reviews new regulations before they are implemented, said Katherine Silverstein, a spokesperson for the National Marine Fisheries Service. She confirmed the fisheries service withdrew the rule on Wednesday.

Conservation groups have long argued that tighter ship speed rules are necessary to protect the whales, in part because warm ocean waters appear to be causing the animals to stray from protected zones. The federal government first announced the proposal in summer 2022 and a coalition of environmental groups sued to try to speed up the finalization of the rules last year.

Some shippers, however, have argued that the rules could be economically devastating to boating and shipping industries.

“This is a huge step forward for American boat manufacturers, coastal economies, and outdoor enthusiasts across the U.S.,” said Frank Hugelmeyer, president and CEO of the National Marine Manufacturers Association, the largest trade association in North America for the recreational boating industry. “The way this rule was drafted gave rulemaking a bad name and created an entirely preventable dynamic.”

THE RIGHT WHALE IS DISAPPEARING

Right whales were once numerous off the East Coast, but their numbers were devastated during the commercial whaling era. They have been a protected species for many years but have been slow to recover.

The whales migrate from their calving grounds off Florida and Georgia in the winter to feeding grounds off New England and Canada in the spring, summer and fall. The journey has become increasingly perilous as the tiny organisms they eat seek colder waters, causing the whales to leave established protected areas, scientists have said.

Conservation groups that have pushed for the finalization of the rules said they were motivated in part by documented collision deaths of right whales in recent years. In one much-publicized case last year, a calf stranded off the state of Georgia had head injuries consistent with a vessel strike, according to government investigators.

The whales numbered more than 480 in 2010, but that fell by more than 25% over the following decade. It has ticked up slightly more recently, but the animal remains critically endangered. Vessel strikes are “a leading cause of the species’ decline,” the National Marine Fisheries Service said in documents.
