• Notice on the End of SAF Eligibility
• Attention UST Owners

The mission of the Tank Programs Division is to protect public health and the environment by preventing regulated substance releases and reducing the risk associated with contaminated sites.

Our core responsibilities include:

• Assuring the proper operation and maintenance of underground storage tank (UST) systems
• Overseeing the cleanup of soil and groundwater contamination from leaking underground storage tanks
• Providing outreach and compliance assistance to keep customers informed and aware of compliance requirements
• Investigating complaints and violations of Arizona's underground storage tanks laws
• Administering payments from the State Assurance Fund (SAF) for reimbursement of eligible costs associated with removal and remediation of leaking USTs.

Phase I and Phase II Reports
The ADEQ UST program does not require and will not review copies of Phase I or Phase II environmental assessment reports. However, if a Phase I or Phase II investigation discovers a UST release, the owner must report the release to ADEQ within 24 hours. If you wish to obtain a no-further-action determination from ADEQ without the involvement of the Tank Programs Division, please contact the ADEQ Volunteer Remediation Program at (602) 771-4809. Please do not call this number if you are seeking information about a UST or LUST.

ADEQ routinely responds to verbal Phase I and Phase II information requests with information obtained from our database. Although the information may be valid, ADEQ recommends that persons preparing Phase I or Phase II reports review the actual UST and leaking UST (LUST) files for factual and detailed information for these reports. The UST/LUST file room can be reached at (602) 771-4344.
