Underground Injection Control (UIC)

UIC Permit Application Completeness Checklist

This checklist is provided to help permit applicants provide the appropriate material that the EPA permit writers need to evaluate the application. Much of the application was originally developed for UIC Class 2 wells and is not always appropriate for UIC Class 5 wells. The BOLD print is the added information. It is advised to organize the permit application in sections that match these sections A‐U. One paper copy of the application with maps shall be provided to EPA. Also provide an electronic copy of the application. A CD included with the paper application works well.
