The Trump administration has finalized a rule that legally permits oil and gas companies operating in Alaska's Beaufort Sea to harm, harass, and even kill polar bears and Pacific walruses through 2031 — as long as those actions are deemed unintentional. The five-year authorization, issued by the U.S. Fish and Wildlife Service in October 2026, applies to the full stretch of Beaufort Sea and North Slope operations where the industry has long sought regulatory cover for the disturbances that inevitably accompany drilling.

What the Rule Actually Allows

Under the Marine Mammal Protection Act, companies cannot take marine mammals without federal authorization — but the law does make room for "incidental" take, meaning harm that occurs as a byproduct of otherwise legal activity. This new rule formalizes that allowance for the oil and gas sector across a broad Arctic footprint. According to the Federal Register, the authorization covers activities including exploration, construction, and production operations — all of which generate noise, physical disruption, and industrial traffic in habitat these species depend on.

The rule's reach is significant. E&E News reported earlier this year that the proposed framework could authorize the killing of polar bear cubs — not just adults — near denning areas on the North Slope. Pregnant females dig dens in coastal snowpack to give birth and nurse through the winter. Industrial activity in those zones can cause mothers to abandon dens or be crushed under equipment.

Animals Already Under Pressure

Polar bears in the southern Beaufort Sea subpopulation have declined sharply over recent decades. NationofChange notes the subpopulation is already stressed by shrinking sea ice, which forces bears to travel farther for food and spend more time on land — directly in the path of North Slope operations. Pacific walruses face overlapping pressures: reduced ice coverage means larger numbers haul out on Alaskan beaches, where they are easily panicked by aircraft, ships, and industrial noise. Stampedes at these haul-out sites can be deadly, particularly for calves.

Truthout and Common Dreams both documented conservation groups' opposition to the rule, with critics arguing the authorization gives industry a blanket shield rather than a narrowly tailored accommodation. Bloomberg Law noted the rule runs parallel to broader administration efforts to expand Arctic energy development — the Beaufort Sea being a central piece of that agenda.

A Rule With Consequences That Last

The authorization runs until 2031. The harm it permits — disrupted dens, injured walruses, animals driven from critical habitat — can compound across years for species that reproduce slowly and recover slowly. Polar bears typically raise one to two cubs every few years. Walruses reach reproductive maturity late. Losses that seem incidental at the individual level accumulate at the population level.

The Fish and Wildlife Service has the authority to rescind or revise this rule. The decision of whether to let it stand is not final — it is a choice, and it is one that can still be changed.
