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. Notification and any details of a public comment period extension will be provided at the web links below and will not be published in local newspapers.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. If no comments are received by the comment deadline, the Director intends to issue a Final UIC Permit, Permit Modification and/or Aquifer Exemption. 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.
