Red Dog's port has carried a top-tier air violation for years with no penalty

The Arctic port that ships ore from the Red Dog mine has carried the federal government's most serious class of air-pollution violation — for airborne dust — for nearly six years, and the state has yet to resolve it through formal enforcement or impose any penalty, according to EPA compliance records.

The violation, for total particulate matter, has stood on the federal record since November 2019 and appears in every quarter the EPA currently displays, flagged as a high-priority case. The record shows no formal enforcement action against the port and total penalties of zero.

Two things temper that picture. The classification is generated by EPA rules from data the state itself supplies, not the state's own account of its enforcement decisions — and the record does not show the state doing nothing. Alaska's Department of Environmental Conservation has evaluated the port 33 times over the five years the EPA displays, issued the operator two warning letters in 2022, and reissued the port's air-quality operating permit in 2023. What the federal record reflects is that none of that has risen to formal enforcement that closes the violation.

The operation behind the violation has a long, documented dust problem. The port ships zinc and lead concentrate from Red Dog, about 55 miles northwest of Kotzebue, on land owned by NANA Regional Corporation, with the operator, Teck, trucking concentrate year-round down a haul road through Cape Krusenstern National Monument to the coast. The nearest tribe, the Native Village of Kivalina, sits about 17 miles away. Dust from that operation has been studied for two decades: after a 2001 federal moss study found elevated metals in the tundra, sampling has since detected lead, zinc and cadmium in road soil, creek water, vegetation, and in marine sediment and water at the port. Monitoring has run since 2004 and now tracks everything from dustfall and soil to caribou tissue and workers' blood-lead levels.

What that monitoring has concluded, so far, is largely reassuring on human health. A risk assessment the state approved in 2007 found no current risks to human health, though it did identify potential risks to the surrounding ecosystem. An earlier state study concluded it remained safe to keep eating subsistence foods from the area. Teck, in materials tied to its 2023 permit, says its own monitoring found no detectable trend in fugitive dust emissions in the port-area records it reviewed.

The federal record leaves open what the state's evaluations actually found and what its warning letters demanded — details that live in DEC's own permit and inspection files, available through a public-records request but not part of the EPA data. Those records also carry no statement from DEC, Teck, the Native Village of Kivalina, the Northwest Arctic Borough or NANA. What the federal database establishes is narrower but not nothing: the most serious tier of Clean Air Act violation, at a still-operating major source next to an Alaska Native village, unresolved on the federal books for close to six years, with no penalty recorded.
