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 4.1.2.1 Classification.

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

Please review the information below. If you have further questions, please call 311 and ask for a ‘Technical Services Review’ request to be created on your behalf.

When are permits required?

Permits are required for the installation, removal, or alteration of any flammable or combustible storage tanks with a capacity greater than 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

Follow these steps to obtain a permit:

  1. Complete the Application to Install/Remove/Alter Storage Tank Systems form.

  2. Submit a completed application to FireTechServices@calgary.ca. Send the required documentation and details to the address listed in our required documentation PDF.

  3. We will review your documentation to verify that you are in full compliance with the National Fire Code (Alberta Edition). If you are in compliance, a storage tank installation permit will be issued. We do charge fees to review plans, please see below.

  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. Standata 19-FCI-018 was issued August 2020 to provide guidance on certification of contractors.

  5. When the installation is complete, a site inspection is required PRIOR to the storage tank being filled. Any Storage Tank Systems with underground components will require additional progress inspections.

  6. Once the final inspection of the installation has been completed, a letter of approval and a storage tank certificate will be issued, unless step 7 (below) applies.

  7. Effective August 31, 2020, Alberta Safety Codes Authority implemented a Storage Tank Inventory Control system for unaccredited areas of the province only, to replace the previous storage tank registration system (Standata 19-FCI-015).

    Calgary Fire Department is accredited (National Fire Code – Alberta Edition 2019 enforcement), and therefore responsible for all Storage Tank Inventory Control system requirements within the City of Calgary.

    For tanks having a capacity of 2500 litres and above, or any tank system with underground components, a Storage Tank System Registration form (listed below) must also be submitted. Once received and reviewed, an Storage Tank System Operator’s Certificate will be issued, allowing the tank to receive product.

    This certificate will be valid for a period of one year from the date of issue. At least 30 days prior to expiry, the tank system owner (or representative) must call 311 to book a “Tank Inspection”. Receiving product (flammable/combustible liquids) without a valid Certificate could result in penalties under the Safety Codes Act.

  8. Commencing January 1 2021, the Calgary Fire Department will begin site inspections of any existing tank system included in the scope of step 7. All records, as required by NFC-AE 2019, must be available upon request by the AHJ. This may include (but is not limited to) periodic testing and inventory control records. A fee will be levied for this inspection and certificate.

    Operators who were required to hold a valid PTMAA registration certificate prior to June 8, 2020, must retain/display this certificate for record. This certificate will be used to receive/store product, until a compliant site inspection outlined above is completed by the Calgary Fire Department (before November 30, 2021).

  9. Should you have further questions, please email FireTechServices@Calgary.ca.

Required documents

When you submit your application for a permit you will need to also submit a variety of documentation for review, which can include three sets of professional drawings. Check the sheets below for the list of required documents.

Professional drawings

Plans, drawings, and specifications need to be submitted in a legible and complete format unless the exemption below applies to your tank. They also require the stamp and seal of a professional engineer who is licensed to practice in Alberta. The plans, drawings, and specifications need to contain sufficient information to allow a Fire Safety Codes Officer to verify full compliance with the National Fir​e Code (Alberta Edition) during an examination of the plans and site inspections.

Exemption - when is a stamp and seal not needed?

A Safety Codes Officer is permitted to review storage tank plans, drawings, and specifications that don’t have an engineered stamp. This only applies to:

  • Individual storage tanks installed outdoors with a capacity less than 8,000 L (including compartments)
  • Tank installations with aggregate capacity less than 20,000 L where all storage tanks and piping are above ground and visible for inspection.

If this applies to your tank then fill out and submit the Small Tank Permit Application to FireTechServices@calgary.ca. If the Officer determines that the installation is of a complex nature, stamped drawings from an engineer may be required.

Penalties for failure to comply?

Failure to comply with the National Fire Code (Alberta Edition) can result in fines and even jail time as outlined in the Safety Codes Act. Failure to comply applies to:

  • Failure to get the necessary permits prior to installing, removing or altering a storage tank.
  • Filling and using a storage tank that contains flammable or combustible liquids, without having a final inspection completed or having prior approval to fill it.

If you are found guilty of non-compliance the consequences can be:

  • For a first offence:
    • Fines up to $100,000 and up to $1,000 for each day where the offense continues and/or
    • Imprisonment for up to 6 months
  • For second offence:
    • Fines up to $500,000 and up to $2,000 for each day where the offence continues and/or
    • Imprisonment up to 12 months
