On September 27, 2022, EPA Region 10 settled with Northern Star (Pogo) LLC for violations of Subtitle C of the Resource Conservation and Recovery Act (RCRA) at its Pogo Mine facility in Delta Junction, 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 Northern Star (Pogo) LLC 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, Northern Star (Pogo) LLC will spend over $100,000 to upgrade sump equipment to meet RCRA closure performance standards, which will result in preventing over 400,000 pounds of hazardous waste from entering the environment. Northern Star (Pogo) LLC will also pay a civil penalty of $600,000.
