EPA Seeks Public Comment on Draft Carbon Storage Permit for Company in Randolph County, Indiana
EPA will host a public availability session and public hearing on Dec. 4
Today, U.S. Environmental Protection Agency (EPA) announced a 49-day public comment period on its intent to issue a permit for One Carbon Partnership to inject and store carbon dioxide underground at the Cardinal Ethanol facility in Randolph County, Indiana.
The process of permanently storing carbon underground is known as “carbon sequestration.” Under the proposed plan, One Carbon Partnership would be permitted to inject up to 450,000 metric tons of carbon dioxide per year for 30 years, and 13.5 million metric tons in total. One Carbon Partnership would be required to monitor the well throughout the injection phase, and for 50 years post-site injection to ensure the stored carbon dioxide remains confined within the injection zone and underground sources of drinking water (USDWs) are not endangered.
The deep formation where the injected carbon would be permanently stored is between 3,100 and 3,659 feet beneath the surface and is protected by a 487-foot-thick confining zone composed of caprock preventing the upward migration of sequestered carbon from the storage reservoir into USDWs. EPA has concluded that One Carbon Partnership’s well materials, intended operation of the well, and the underlying geology of the proposed storage site are appropriate to prevent endangerment of USDWs.
EPA will host a public availability session followed by a public hearing on December 4 to engage in conversation, answer questions on the draft permit and record public comments. Comments may also be submitted in writing.

- Thursday, December 4
