CO2 sequestration well approved for Arizona

EPA this afternoon announced, "The Arizona Department of Environmental Quality [ADEQ] and U.S. Environmental Protection Agency have issued permits authorizing the West Coast Regional Carbon Sequestration Partnership (WESTCARB) to inject 2,000 tons of carbon dioxide into an underground saline formation in Joseph City, west of Holbrook.

The carbon dioxide injection will occur on Arizona Public Service Company’s Cholla Power Plant property in Navajo County at a depth of about 3,500 feet. We expect drilling to commence fairly soon.

The WESTCARB injection project is sponsored by APS with funding from the Department of Energy. AZGS is a member of WESTCARB.
