Flammable or Combustible Tank Permits
The Calgary Fire Department is the authority having jurisdiction in the City of 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 Alberta Fire Code (AFC) Division B Article 220.127.116.11. Classification.
These requirements also apply to tanks that contain windshield 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 L. 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.
Follow these steps to obtain a permit:
- Complete the Application to Install/Remove/Alter Storage Tank Systems form.
- Submit a completed application to FireTechServices@calgary.ca. Send the required documentation and details to the address listed in our required documentation pdf.
- 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.
- Installation of the storage tank can begin, as per the approved plans. The installation needs to be performed by an accredited installer who is registered in good standing with either the Petroleum Tank Management Association of Alberta (PTMAA) or the Canadian Petroleum Contractors Association (CPCA).
- When the installation is complete, a site inspection is required PRIOR to the storage tank being filled.
- Once the final inspection of the installation has been completed, a letter of approval and a storage tank certificate will be issued. If the storage tank has a capacity over 2500 L, a notification letter will be sent to the Petroleum Tank Management Association of Alberta.
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.
- Underground Storage Tanks
- Aboveground Storage Tanks
- Building Storage Tanks (Inside buildings)
- Waste-oil Storage Tanks
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 Fire 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.
Are there consequences for not complying?
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
