On August 4, EPA announced a proposal to exempt from the Resource Conservation and Recovery Act’s federal hazardous waste regulations, carbon dioxide captured from coal-fired power and other industrial plants and injected underground for sequestration. The proposed rule would apply only to carbon dioxide streams injected into Class VI wells - specifically designed for CO2 geologic sequestration; however, as of today, there are no Class VI wells in operation. These wells are subject to more recent regulations under the Safe Drinking Water Act requiring them to be appropriately sited, constructed, tested, monitored, and closed to prevent groundwater contamination.
