On June 7, 2024, EPA Region 10 settled with Teck Alaska for violations of Subtitle C of the Resource Conservation and Recovery Act (RCRA) at its Red Dog Mine facility near Kotzebue, Alaska. The implementing regulations of RCRA require that generators of hazardous waste must manage the hazardous waste in compliance with the RCRA requirements in order to protect human health and the environment. EPA alleges that Teck Alaska failed to properly determine that wastes generated in its laboratory were hazardous wastes, and further stored, treated, and disposed of hazardous waste without a RCRA permit. As part of the terms of the settlement, Teck Alaska will spend approximately $50,000 to upgrade sump equipment to meet RCRA closure performance standards, which will result in preventing approximately 29,000 pounds of hazardous waste from entering the environment each year. Teck Alaska will also pay a civil penalty of $429,794.
