UST State Lead Corrective Action Program

Under the State Lead Corrective Action Program, Underground Storage Tank (UST) owners, operators and property owners can apply to have ADEQ manage the hiring and overseeing of qualified professionals needed to perform investigative and cleanup actions in response to a release.1

Application Information

Applications may be prioritized based on site-specific criteria related to risk and available financial resources in the UST revolving fund that have been allocated for this purpose. Application process steps:

  1. Applicant completes and submits the State Lead Program application for corrective action | Download Application >
  2. ADEQ reviews the application and contacts the applicant if any further information or clarification is required. 
  3. ADEQ notifies the applicant once the application is approved, explains next project steps and keeps the applicant informed throughout the corrective action process until the release is closed.


Only complete application submittals (including attachments) will be processed. You are eligible to apply if you are a:

  • Leaking UST owner
  • Leaking UST operator
  • Current property owner of a site where a leaking UST release occurred

Financial Options

Leaking UST owners and operators and leaking UST owners or operators who also own the property where the release occurred may request a financial need evaluation by completing Appendix B (Pages 11 through 22) of the State Lead program application.

Property owners who are not also leaking UST owners or operators are encouraged to contact ADEQ directly to discuss available options.
