With the rapid increase in carbon capture and sequestration (CCS) projects around the country, including right here in the Marcellus/Utica region, a key issue has arisen. Where does one store (sequester) all that carbon dioxide (CO2)? The answer is underground in a Class VI injection well. Class VI wells are a relatively new classification for injection wells, created by the federal EPA in 2010. Who regulates Class VI wells is a current flashpoint of controversy. Right now, the EPA is the primary regulator (has “primacy”) in regulating Class VI wells in all but two states (neither of which is a Marcellus/Utica state).
