Flammable or Combustible Tank Permits

The Calgary Fire Department is the authority in Calgary for the installation, removal or alteration of flammable and combustible liquid storage tanks. You can learn what classifies as a flammable or combustible liquid in the National Fire Code – Alberta Edition 2019 (NFC-AE) Division B Article Classification.

These requirements also apply to tanks that contain wind​shield washer antifreeze. Windshield washer antifreeze has been classified as a 1C flammable liquid.

When are permits required?

Permits are required for the installation, removal, or alteration of any flammable or combustible storage tanks with a capacity of over 230 litres. This includes outside aboveground storage tanks (AST), underground storage tanks (UST), inside building storage tanks (BST), and waste-oil storage tanks (WST).

How soon do I need a permit?

You need to have a permit before the installation, removal, or alteration of a storage tank. If you don’t have a permit you will be in violation of the Safety Codes Act of Alberta which can result in fines and/or jail time.

Permit process

  1. Complete the Application to Install/Remove/Alter Storage Tank Systems form for ins tallations or removals.

  4. Installation of the storage tank can begin as per the approved plans. In accordance with the National Fire Code - 2019 Alberta Edition, only individuals who are approved by the provincial Fire Administrator are permitted to install, remove, repair or conduct precision tests on petroleum storage tanks and equipment. The power to approve petroleum tank contractors has been delegated by Ministerial Order No. TCS:002/20 to the Administrator of Certification (Administrator) with the Safety Codes Council (Council). This power was formerly delegated to the Petroleum Tank Management Association of Alberta (PTMAA). All individuals with a valid certification as of June 8, 2020 remain approved to work in Alberta. View the list of approved contractors. Removal of underground tanks, or removal of systems with any underground components, must also have a certified remover present to supervise.
  5. When the installation is complete, a site inspection is required PRIOR to the storage tank being filled.
  6. Once the final inspection of the installation has been completed, a letter of approval and a storage tank certificate will be issued.

    • As of June 8, 2020, the administration of the storage tank system program in unaccredited areas of Alberta was transferred from the Petroleum Tank Management Association of Alberta (PTMAA) to the Alberta Safety Codes Authority (ASCA), a division of the Safety Codes Council. Further details regarding the transfer of authority can be found in the Fire STANDATA 19-FCB-007. A subsequent Fire Code Interpretation, STANDATA 19-FCI-015, was recently issued related to the National Fire Code - 2019 Alberta Edition regarding Storage Tank System Inspections and Inventory Control. ASCA has been delegated the authority for storage tank systems in unaccredited areas of Alberta.
    • The City of Calgary is an accredited jurisdiction, and has therefore assumed responsibility for the construction, upgrading, leak testing oversight, closure, removal, maintenance, operation standards and notification of leaks, spills, and contaminated soils. This is effective immediately.
    • Current holders of a PTMAA registration certificate (issued prior to June 8 2020, valid until August 31 2020) must retain/display this certificate for record, to show compliance PRIOR to June 8 2020.
