Maximum Tank Capacity

Maximum Tank Capacity

The Fire Code limits individual capacity of storage tanks (where flammable liquids are stored) at fuel dispensing facilities to 50,000 litres. Regardless of the number of compartments in an individual vessel, the maximum capacity of all compartments added together may not exceed 50,000 litres. An exception to this requirement is where only diesel fuel is stored and dispensed at the facility. In that case an individual storage tank may be up to 75,000 litres. The maximum total capacity for a fuel dispensing facility is 150,000 litres.

A province-wide variance has been released by Alberta Municipal Affairs permitting individual tank size to be a maximum of 80,000 litres. The maximum aggregate capacity will change to 200,000 litres. An option is available to have individual tank capacity larger than 80,000 litres but the tank must be constructed to the protected tank standard of ULC-S655.

The PTMAA strongly supports this change which we believe will result in fewer spills and hazardous conditions with tanks able to accept larger deliveries.
