Alaska DEC proposes reissuing statewide suction dredge mining permit

The Alaska Department of Environmental Conservation posted a formal notice on May 5, 2026, proposing to reissue APDES General Permit AKG371000, the statewide authorization that allows medium suction dredge placer miners to discharge process water into rivers and streams across Alaska. The permit covers suction dredges with intake diameters greater than six inches and less than or equal to ten inches, and authorizes those discharges subject to APDES effluent limits and monitoring requirements. Miners operating in that size range depend on the permit to run seasonal operations; a lapse or changed conditions could affect work mid-season.

What the Permit Covers and Who Has a Stake

The reissuance would continue statewide authorization for placer mining operations using medium suction dredges, subject to APDES effluent limits and monitoring requirements. Alaska's placer districts overlap with rivers that support salmon and subsistence fishing, and tribal governments and fishing interests have raised concerns about suction dredge operations in those watersheds. The Karuk Tribe has argued that suction dredges use "motorized vacuums to extract gold from riverbeds" in ways that "release toxic mercury left over from historic mining, destroy fish spawning habitat, and damage Tribal cultural sites." Whether those concerns are shared by Alaska tribal governments and subsistence users in affected watersheds is a question the public comment process may surface.

The draft permit and fact sheet are available for review at DEC administrative offices in Anchorage, Fairbanks, Juneau, Soldotna, and Wasilla, as well as through the DEC website. The designated permit contact is Nick Dallman. DEC will issue a response-to-comments document when the final permit is released.
