Revised On: Nov. 13, 2023 - 6:00 p.m.

The Preapproval Program provides financial assistance to support facilities with contamination from a leaking underground storage tank (UST). As part of the preapproval application process, ADEQ helps customers focus on the specific tasks, schedules and expected budgets for completing the required cleanup work for their site.

For UST owners and operators who can demonstrate compliance with financial responsibility requirements, ADEQ provides reimbursement limited to costs not covered by the applicable financial assurance mechanism.

The ADEQ Preapproval Program does not provide federally and state required coverage for UST releases and third-party damages. This means funding through the ADEQ Preapproval Program is not financial assurance and cannot be used to demonstrate compliance with financial responsibility. The financial assurance mechanism(s) utilized by UST owners and operators to demonstrate compliance with financial responsibility requirements is primary to eligibility for state reimbursement funding.

UST owners and operators relying on UST insurance to demonstrate compliance with financial responsibility (FR), activities conducted, and costs incurred without following notification requirements under their UST insurance policy may be denied insurance coverage and may not be eligible for reimbursement under this program.
