EPA proposed draft permits Tuesday for Exxon Mobil’s planned storage of carbon dioxide in southeast Texas.
The Region 6 office issued a public notice saying the agency plans to issue three Class VI well permits for Exxon’s Rose Carbon Capture and Storage project in Jefferson County that would draw CO2 from unidentified industrial emitters.
The project would store the climate-warming gas in rock formations that are between 3,400 and 7,800 feet beneath sea level, an EPA fact sheet said. The company would be able to inject a total of 5 million metric tons per year across all three wells, the document also said, and Exxon requested a 13-year injection period.
The project would take CO2 from “high-concentration” sources like “clean” hydrogen and ammonia facilities, according to EPA’s fact sheet. The three draft permits, along with Exxon’s application, were all posted to an online docket.
