Regulations and permits

The regulations and permits for removing old fuel tanks vary depending on the location and type of tank. Here are some general guidelines:

Regulations

The Technical Standards and Safety Authority (TSSA) regulates aboveground and underground fuel oil storage tanks. There is no mandatory age for replacing an approved aboveground tank as long as it is not leaking. Aboveground fuel oil tanks are considered approved if they were installed following the code at the time of installation. However, installing an "Inside Tank" (certified for indoor use) outdoors would void its approval.

For underground tanks, it is challenging to detect leaks, and small leaks may go unnoticed for years. If you suspect a leak, contact your fuel supplier for assistance in finding underground tank testing companies. In the event of a fuel oil spill during tank removal, you must notify the Spills Action Centre of the Ministry of Environment and Energy.

Permits

In some states, such as Florida, a permit may be required before removing a fuel tank. It is essential to check with your state or local regulatory agency, as non-adherence can lead to penalties. For example, in Massachusetts, a permit from the fire department is necessary for removing an old fuel tank, and the tank must be taken to a licensed recycling facility.

Additionally, only a TSSA-registered petroleum contractor is qualified to remove underground or buried fuel oil tanks. Before hiring a contractor, ensure they are registered with TSSA and ask for their registration number.

When removing an old fuel tank, it is crucial to consult with a fuel tank disposal expert or an environmental consulting company to ensure compliance with all applicable regulations and to avoid any safety hazards.
