Class VI Primacy for authority to regulate Geologic Storage of Carbon Dioxide

Return to Oil & Gas Home Page
The Oil and Gas Division primary regulatory authority (Primacy) over Class VI injection well activities in the State of North Dakota.  
On December 10, 2010 the EPA finalized federal requirements for the geologic storage of carbon dioxide under the authority of the federal Safe Drinking Water Actís Underground Injection Control (UIC) Program, creating a new class of injection well, Class VI.  These requirements, also known as the Class VI Rule, are designed to protect underground sources of drinking water based on the UIC Program regulatory framework with modifications to address the unique nature of carbon dioxide injection for the primary purpose of long term storage.  As of September 7, 2011 the EPA is the acting regulatory authority in all States, including North Dakota.  Under the federal UIC program each State must apply for primacy by demonstrating, through application, to the EPA that its Class VI UIC Program is at least as stringent as the federal standards.  

On June 21, 2013 the official North Dakota Class VI primacy application was submitted to the EPA and was approved April 24, 2018.
