Current Class VI Projects under Review at EPA

The dashboard below contains information on Class VI permit applications that are currently under review at EPA. Please note that each Class VI well requires an individual well application and permit. However, wells are grouped by project in the dashboard below for ease of viewing. This data is updated periodically.

Class VI applications in states that have been granted Class VI Primary Enforcement Responsibility (primacy) have been transferred to those respective states and are not tracked here. Please see the links below for more information on Class VI projects in states with primacy.

For more information on Class VI primacy, please see EPA's UIC Primacy webpage.

EPA aims to review complete Class VI applications and issue permits when appropriate within approximately 24 months. This timeframe is dependent on several factors, including the complexity of the project and the quality and completeness of the submitted application. It is important for the applicant to submit a complete application and provide any information requested by the permitting agency in a timely manner so as not to extend the overall time for the review.

See below for an explanation of the steps in the permitting process shown in the tracker:

Completeness Review: The first step of the review is determining that the permit application is complete and contains all of the required information. Completeness reviews typically take 30 days for applications where Notice of Deficiencies (NODs) are not needed. EPA has developed a series of templates to help applicants develop a complete permit application.
- Review the Class VI permit application completeness checklist.
- Notice of Deficiency: A NOD identifies any required information that is missing from an application. NODs are sent to the applicant, who must provide the missing information before the application can be deemed complete.
Technical Review: After an application is determined to be complete, the Technical Review will begin. This involves a thorough review of all application materials and an ongoing dialogue with the applicant to understand the proposed project and ensure that it will be constructed and operated in a manner that will not endanger USDWs. This is accomplished through an ongoing dialogue between the applicant and the permitting authority.
- Request for Additional Information (RAI): An RAI is a formal request from the permitting authority that additional information be provided to address questions that arise during the Technical Review of the application. RAIs are sent to applicants, who must provide the requested information for the agency to evaluate the suitability of the proposed project. Applicants should respond with 30 days or provide an alternative timeline if necessary to prepare the response.
Prepare Draft Permit: If the technical review determines that the permit application meets the requirements of the Class VI Rule and the proposed project is suitable for CO₂ injection for GS, a draft permit will be prepared, specifying the conditions that the well would be able to operate under. The permit includes the Class VI Project Plans as enforceable conditions.
Public Comment Period: Public comment periods allow the public an opportunity to review and provide comment on the draft permit. The public comment period is also when the public can request the Agency to conduct a hearing on the draft permitting decision.
Prepare Final Permit: The final permit is prepared with modifications based on feedback received during the Public Comment Period, where appropriate. Additionally, the agency prepares a document with responses to comments received. A final permit authorizes the applicant to construct or convert the injection well and monitoring wells and perform required preoperational testing.
