Federal permits are required for all Class I, II, and III wells, and some Class V wells. For a permit application or related information, please see Region 9 contacts or visit the UIC Reporting Forms site. Region 9 states that have delegated programs have permit requirements that vary by jurisdiction and well type. Injection well owners are responsible for determining all applicable requirements. Permit requirements can be found in 40 CFR parts 124, 144 and 146.
Additional UIC information can be found at EPA's National UIC web site. For general questions, call the Safe Drinking Water Act Hotline at (800) 426-4791.
EPA is supporting national Environmental Justice (EJ) goals by inviting communities to provide input during the permit application review process. To support early engagement between permittees and overburdened communities, EPA's Region 9 office has developed an Environmental Justice and Permitting Implementation Plan which the region follows in processing applications for EPA-issued UIC permits. In addition, EPA has developed a community engagement guide for potential permitees, entitled Promising Practices for Permit Applicants Seeking EPA-Issued Permits: Ways to Engage Neighboring Communities.
