“Class VI UIC; What is it? Where is it? How does it work?“

Presented by: 

Lisa Alpert

Abstract: 

UIC Class VI (CO 2 injection) projects are regulated by the Environmental Protection Agency (EPA) unless a state receives primacy through the EPA primacy application process. The current state of Class VI primacy will be discussed, with a focus on the status of Class VI projects in California, which are dominated by California Resources Corporation (through Carbon TerraVault, LLC) projects. The most advanced Class VI project in California is CTV’s Elk Hills 26R Project, which is currently the only project to receive approval to construct injection wells in the EPA Region 9, which encompasses California, Arizona, Hawaii, Nevada, Guam, and American Samoa. An overview of the general requirements for Class VI projects will be discussed.
