The first-ever "permanent" CCS site in the country is in Decatur, IL. Permanent is in quotes because the project, which has been in operation for only 13 years, has already had two leaks, one of which migrated above the capstone that ADM said would contain it "forever."
While hiding the leak from the city, the public, elected officials, and the EPA, ADM negotiated a 99-year easement from the city to expand their project. The expanded project's Area of Review (a term used to indicate the area at greatest risk for water contamination) covers 224 acres of the county's 580 acres of land, including the entire city of Decatur and Lake Decatur, the city's water supply.
