Ban on Carbon Injections Within Mahomet Aquifer Heads to Pritzker's Desk
- The Illinois General Assembly passed Senate Bill 2317 on May 20, 2025, banning carbon sequestration within the Mahomet Aquifer footprint and sent it to Gov. JB Pritzker.
- The bill followed concerns arising from a carbon leak at Archer Daniels Midland's Decatur facility, which temporarily paused injections after a corroded well pipe released 8,000 metric tons underground last October.
- The Mahomet Aquifer underlies 15 counties in Central Illinois, supplying over 100 million gallons daily as the sole drinking water source for nearly one million residents, including Normal and Champaign.
- The bill passed the House 91-19 and the Senate unanimously 55-0, though it excludes some recharge areas to accommodate One Earth Energy's pending pipeline permit, and some business groups urge a veto citing concerns over clean energy investment.
- The legislation includes the formation of a commission to examine carbon sequestration activities near the Mahomet Aquifer, reflecting a careful stance due to the absence of alternative water supplies and contrasting opinions on the safety of sequestration in Illinois.
