ADM's "Carbon Capture" Site In Illinois Sprang Leaks; ADM Didn't Disclose This For Months While Pressing For An Easement

EDIT

In September, the public learned of a leak at ADM’s Decatur site after it was reported by E&E News, which covers energy and environmental issues. Additional testing mandated by the EPA turned up a second leak later that month. The EPA has confirmed these leaks posed no threat to water sources. Still, they raise concern about whether more leaks are likely, whether the public has any right to know when leaks occur, and if CCS technology is really a viable climate solution. Officials with Chicago-based ADM spoke at the Decatur City Council meeting immediately after Rosenberger. They tried to assuage her concerns. “We simply wouldn’t do this if we didn’t believe that it was safe,” said Greg Webb, ADM’s vice president of state-government relations.

But ADM kept local and state officials in the dark for months about the first leak. They detected it back in March, five months after discovering corrosion in the tubing in the sequestration well. However, neither leak was disclosed as the company this spring petitioned the city of Decatur for an easement to expand its operations. The company also remained tight-lipped about the leak as it took part in major negotiations over the state’s first CCS regulations, the SAFE CCS Act, between April and May, according to several parties involved.

As a result, when Illinois Governor J.B. Pritzker signed those CCS regulations into law at ADM’s Decatur facility in July, he was unaware of the leak that had occurred more than 5,000 feet below his seat, his office confirmed. “I thought we were negotiating in good faith with ADM,” bill sponsor and state Senator Laura Fine, a Democrat, said in a statement. “When negotiating complex legislation, we expect all parties to be forthcoming and transparent in order to ensure we enact effective legislation.”

It’s unclear whether ADM was required by law to report the leaks any sooner than it did. According to the company’s permits, it only has to notify state and local officials if there are “major” or “serious” emergencies. The EPA wouldn’t comment on whether ADM was required to disclose, and neither the EPA nor ADM would confirm if the two leaks in Decatur qualified as “minor” emergencies.

Central Illinois is becoming a hotspot nationwide for the nascent CCS industry because of the Mt. Simon Sandstone, a deep saline formation of porous rock especially suitable for CO2 storage. It underlies the majority of Illinois and spills into parts of Indiana and Kentucky. It has an estimated storage capacity of up to 150 billion tons of CO2, making it the largest reservoir of its kind anywhere in the Midwest. However, there is concern that pumping CO2 into saline reservoirs near subsurface water risks pushing pressurized CO2 and brine toward those resources, which would pose additional contamination risks. “Brine is pretty nasty stuff,” said Dominic Diguilio, a retired geoscientist from the EPA Office of Research and Development. “It has a very high concentration of salts, heavy metals, sometimes volatile organic compounds and radionuclides like radium.”
