More than 150 environmental and advocacy groups are asking EPA to halt carbon dioxide injections nationwide and stop permitting new wells until regulations are revised.
In a letter to EPA Administrator Michael Regan on Tuesday, the groups pressed the agency “to take immediate action to update rules and regulations for CO2 injection wells,” pointing to a leak detected earlier this year at a CO2 injection site in Decatur, Illinois.
Agribusiness company and well operator Archer-Daniels-Midland has said drinking water was not endangered by the leak, which was tied to corrosion in a monitoring well.
Although ADM paused injection last month after company tests pointed to a second suspected leak — this time of salty water — concern about the incident and EPA’s response hasn’t abated.
