Waste Programs Division: State Lead Program
State Lead Program

Since 1989, Arizona statutes have included provisions for ADEQ to take corrective actions to address releases of regulated substances (petroleum) from Underground Storage Tank(UST) systems. State action is authorized if ADEQ's Director determines that it's necessary to protect public health and the environment.

ADEQ's State Lead program manages these projects based on the statutes listed below:

State Lead projects have included site assessments, off-site investigations, remediation, risk assessments, and UST removals. In accordance with state procurement requirements, State Lead projects are contracted using a bid process among qualified contractors. Projects are prioritized based on threat to human health and the environment.

Persons potentially eligible for the State Lead program include:

  • Property owners who did not own or operate the UST system associated with the release (referred to as an “orphan” releases)
  • Leaking Underground Storage Tank Owner/Operators who are financially and/or technically incapable of managing the cleanup
  • LUST Owner/Operators who are required to provide State Lead access to conduct corrective actions under an enforcement action

If a viable LUST owner/operator exists, cost recovery will be made against them as the responsible party. LUST Owner/Operators may apply for a financial need evaluation and may qualify for a financial settlement. See Arizona Revised Statute §49-1017.01 for more information.

State Lead ARRA projects

EPA Region 9 gave ADEQ a Recovery Act grant of $3,219,000 for UST cleanup releases. ADEQ used the funds to perform site assessments and remediations at 26 sites located throughout Arizona. The grant started in July, 2009 and ended in September, 2011.

LUST sites that were addressed using ARRA funds were located primarily in rural parts of Arizona, including gasoline service stations or other businesses in Prescott, Holbrook, Parker, Willcox , Dewey-Humboldt, Coolidge, Safford, Winslow, Globe, Williams, Wellton, and Somerton, the communities of Clay Springs, Greer, Sonoita and Truxton, and a school in Yuma.

“EPA is extremely pleased with ADEQ's efforts to work with us to speed environmental cleanups that support jobs and economic development,” said Jeff Scott, director of the Waste Management Division for EPA’s Region 9 in San Francisco.

Red Rock UST Removal

Located between Phoenix and Tucson off Interstate 10, Red Rock, Arizona is a mostly an agricultural area, although the city has recently seen construction of tract home communities. ADEQ was at an abandoned gas station as part of their State Lead program where they removed three 8,000 gallon steel tanks used for gasoline storage and one 550 gallon tank used to house hazardous materials in order to adequately assess contamination risks.

LUST Grant Projects

EPA Region 9 has provided special project funding to assist ADEQ in completing site assessments on several abandoned UST sites across Arizona. The EPA's funding has allowed ADEQ to work on 15 UST sites, removing USTs and completing assessments. Several of those sites required additional cleanup which is being managed by the State Lead program with the costs being covered through the regulated substance fund.

Route 66 InitiativeRoute 66 Initiative

The goal of the Route 66 initiative focused on the removal of abandoned (orphan) underground storage tanks and the identification and remediation of releases from USTs. ADEQ provided both technical and financial assistance to eligible persons towards cleaning up UST contamination. This successful program required communication and cooperation among ADEQ, EPA, UST owners, operators, and property owners, local officials, and the communities along Route 66.

Benefits of the Initiative:

  • Reduction in risk to human health and the environment
  • Revitalization of cities and towns
  • Increased property values

County and Municipal Tank Closure Program (MTCP)

MTCP assisted small communities by removing abandoned USTs and cleaning up the contamination from UST releases. The program operated at no cost to the property owner or the community. Program funding of approximately $2,000,000 provided for the removal of 250 tanks at 115 facilities and included the cleanup of 17 releases. This program is no longer supported. For more information, you can read the Arizona Revised Statute § 49-1073.

On May 2 and 3, 2011 the ADEQ State Lead Unit supervised the removal and off-site disposal of three underground storage tanks (USTs) from a former gasoline service station located along Highway 77 in Mammoth, Arizona owned by the Cittadini Family. Funding for the removal operations was provided through the agency’s Municipal Tank Removal Program. The analytical results for soil samples collected beneath the UST system components did not indicate that a gasoline release(s) had occurred at the site and no further action was required.

Route 66 InitiativeNonCorrective Action Program

To view the most updated information on the UST NonCorrective Action Program, visit the new website at www.azdeq.gov/ust-state-lead-noncorrective-action-program


2015 legislation expanded the abilities of ADEQ’s State Lead Program to conduct three types of “noncorrective” actions. ADEQ’s State Lead program will be responsible for hiring and overseeing the qualified professionals needed to perform the actions. In accordance with A.R.S. 49-1017.02, the noncorrective actions included in the State Lead Program include the following:

Type of Action
UST for permanent closure
Confirmation of a suspected release
Baseline Assessments

Eligible applicants include UST owners, operators and property owners. An applicant may request more than one type of action for the UST facility. Participation requires the State Lead Program to have permission from the current property owner to conduct the work. 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.

If LUST cleanup is needed, the applicant may request that the State Lead Program conduct corrective actions at the facility.

If you have questions regarding this program, please contact [email protected] or Michael Latin by phone at (602) 771-4308.

Application Forms:

Note: To complete the application, you will need the ADEQ assigned facility ID number, and the name and address of the UST facility. If you do not have this information readily available, you may search for it online using ADEQ’s UST database: http://www.azdeq.gov/databases/ustsearch.html.
