In accordance with the requirements of 40 CFR Section 124.10, EPA’s Region 8 UIC Program is soliciting public comment on issuance of its permit-related actions under the authority of the Safe Drinking Water Act and UIC Program regulations. These actions, noted in the attachment below, would authorize the injection of fluids into the subsurface for the purpose of either enhancing the production of oil and gas resources or disposal of produced water associated with these operations, and may include a proposed Aquifer Exemption of the Proposed Injection Zone(s), per 40 CFR Section 146.4(b)(1). If an Aquifer Exemption is proposed, the portion(s) of the aquifer(s) to be exempted and the basis for EPA’s proposed exemption is included.

Comments are requested for no less than 30 calendar days from the last date EPA publishes its announcement of each action. All comments received by the end of the comment period will be considered in the formulation of any final decisions. If no comments are received by the comment deadline, the Regional Administrator of EPA Region 8 intends to issue a Final UIC Permit 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 call or email the EPA contact person listed with the permit.
