The U.S. Environmental Protection Agency (EPA or the Agency) is revising the regulations for hazardous waste management under the Resource Conservation and Recovery Act (RCRA) to conditionally exclude carbon dioxide (CO<INF>2</INF>) streams that are hazardous from the definition of hazardous waste, provided these hazardous CO<INF>2</INF> streams are captured from emission sources, are injected into Underground Injection Control (UIC) Class VI wells for purposes of geologic sequestration (GS), and meet certain other conditions. EPA is taking this action because the Agency believes that the management of these CO<INF>2</INF> streams, when meeting certain conditions, does not present a substantial risk to human health or the environment, and therefore additional regulation pursuant to RCRA's hazardous waste regulations is unnecessary. EPA expects that this amendment will substantially reduce the uncertainty associated with identifying these CO<INF>2</INF> streams under RCRA subtitle C, and will also facilitate the deployment of GS by providing additional regulatory certainty.
