Storage Tanks

Storing products and chemicals such as heating oil, diesel fuel, gasoline, acids, and bases in tanks, whether underground or above ground, raises concerns about leaks, spills, and overfills. Environment, Health & Safety (EHS), Environmental Protection & Permitting Program (EP3) manages the above ground and underground tank systems at University of Michigan (U-M).  EP3:

  • Oversees environmental issues, such as leaks, spills, and overfills, associated with U-M tank systems
  • Reviews tank system installation information and facility site plans prior to being submitted to the State of Michigan
  • Communicates with the State of Michigan on behalf of U-M

Contact EP3 at (734) 936-1920 when needing to communicate or submit information to the State of Michigan.

Plan Review and Certification for Above-ground Storage Tanks

The State of Michigan must review and certify:

  • A facility that supplies flammable liquids or combustible liquids (FL/CL) which has an individual tank storage capacity of more than 1,100 gallons and contains a liquid with a flash point of less than 200 degrees Fahrenheit.
  • A flammable compressed gas or liquefied petroleum gas container filling location
  • A facility that supplies flammable compressed gas or any liquefied petroleum gas which has a tank with a water capacity of:
    • More than 2,000 gallons
    • Two or more tanks with an aggregate water capacity of more than 4,000 gallons

Process for Installing Above-ground Storage Tanks

Project managers must:

  • Complete the Application for Installation of Aboveground Storage Tanks for tanks needing to be certified (see list above)
  • Submit to EP3:
    • A completed Application for Installation of Aboveground Storage Tanks
    • A facility site plan showing locations of storage tanks, buildings, property lines, etc must be submitted with the application
    • $203/tank certification fee
  • Have the State of Michigan inspect and certify the AST prior to service

Inspection and Registration

All ASTs must be inspected on a triennial basis and registered annually.  The registration fee is $61.50.

Plan Review and Certification for Underground Storage Tanks

The State of Michigan must review and certify any Underground Storage Tank (UST) system that stores a hazardous substance.

Process for Installing Underground Storage Tanks

Forty-five days prior to installing a UST system, project managers must:

  • Complete the pre-registration form Notice of Proposed Installation of Underground Storage Tank Registration
  • Submit to EP3:
    • The completed pre-registration form Notice of Proposed Installation of Underground Storage Tank Registration
    • The requested additional information according to the pre-registration form Notice of Proposed Installation of Underground Storage Tank Registration form

Inspection and Registration

The State of Michigan conducts two inspections for UST installations.  Project managers must:

  • For the first inspection by the State of Michigan, notify EP3 no less than seven days before installation of the UST
  • For the second inspection by the State of Michigan, complete the Registration of Underground Storage Tanks form
  • Submit to EP3 the:
    • The completed Registration of Underground Storage Tanks form
    • $100 registration fee (an annual fee)

NOTE: All UST systems must be registered annually.  The registration fee is $100.00.

Decommissioning Above-ground and Underground Storage Tanks

For tanks that are no longer needed, or have been orphaned (found with no indication of ownership), contact EP3 at (734) 936-1920 as soon as possible.  U-M only has a limited time to remove these tanks.  EP3 will manage the project to remove the tank.  However, departments may incur costs to register the tank, conduct an environmental assessment, or both.

Noticeable Release of Tank Contents

Contact EP3 is a suspect release of tank contents is found.  EP3 will manage the remediation project.
