Regional Guidance Documents

EPA Region 8 directly implements the Underground Injection Control Program under the SDWA in Indian country and the UIC programs for non-oil and gas related activities in Colorado, Montana, and South Dakota. These guidance assist the regulated community - which consists of hundreds of drinking waters systems and injection well operators, many of which are small and in rural areas – in complying with program requirements.

Permit Applicant:

The Class II Permit Application Completeness Review Checklist is intended to assist EPA staff’s review of the permit application during the Administrative Review process. This checklist can also serve as a useful guide as you prepare your Class II permit application and can be used for other well class applications.

Attachment K lists additional federal laws that EPA must comply with before a new permit can be issued. The National Historic Preservation Act and Endangered Species Act requirements will apply to most permits issued by EPA Region 8. If the applicant is willing and able to initiate and complete the cultural resource and endangered or threatened species surveys, inclusion of the survey and/or consultant’s reports with the permit application can significantly expedite the permitting process. If previous, recent surveys have already been conducted, the results of those surveys are acceptable to include with the application.

In addition to the permit application, Region 8 also requests that the applicant complete the attached spreadsheet to assist the EPA in technical review of the permit application.
