Announcements and Public Notice of Proposed Actions

EPA Region 8 solicits public comment on issuance of permit-related actions under the authority of the Safe Drinking Water Act and UIC Program regulations for a minimum of 30 calendar days on this website and publishes a courtesy announcement in one or more local newspapers.

All comments received by the end of the comment period will be considered in the formulation of any final decision. Due to office closures related to the COVID-19 outbreak, at this time please do not submit comments via regular mail. Notification and any details of a public comment period extension will be provided at the web links below and will not be published in local newspapers. Interested parties on our email list will be notified of any extension of the public comment period by email.

If you wish to be added to our email list, please notify the EPA staff listed for the proposed action. After the comment period has closed, the Director intends to issue a Final UIC Permit, Permit Modification and/or Aquifer Exemption decision. EPA will hold a public hearing if the response to a specific action indicates significant public interest, or if requested.

For additional information on a specific action, please contact the EPA staff listed for that proposed action.

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.


Resources for Owners and Operators

  • 7520 reporting forms for owners or operators
  • Class II Permit Application Checklist & Spreadsheet
  • Mechanical Integrity Test (MIT) Form
  • UIC Inspector Training 2018
  • UIC Inspector Training 2019
  • 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.
