LOBLAW COMPANIES LIMITED - Approval for variance from the Liquid Fuels Handling Code

Liquid Fuels Handling Code (LFHC) Requirements that Would Not be Met:

3.3.1.1.1 An aboveground storage tank shall be diked in accordance with

(a) this Code; or

(b) in the absence of requirements for such systems in this Code, the

provisions of the Ontario Fire Code (notwithstanding any exemption in

the Ontario Fire Code from the Technical Standards and Safety Act,

2000).

Why the Code Would Not be Met

• A 100,000 L double wall tank will keep the previous site design as standard to have additional capacity in case of change in codes.

Safety Assessment

• The tank will meet the intent of clause 3.3.2.1 of the LFHC 2017 that allows tanks with a maximum capacity 80,000 L and conforming to an approved standard for tanks with secondary containment to be installed without a dike:
• The tank conforms to an approved standard for tanks with secondary containment (certified to ULC S601, vacuum monitored)
• The control system in conjunction with the electronic tank inventory system will stop the pump and close the motor operated tank fill valve when the tank is filled to 72,000 Litres under normal operating conditions.
• The overfill switch independent of tank inventory system will limit the maximum over fill level to 76,000 Litres and will sound audible alarm, close the motor operated tank fill valve and shutdown the tank filling pump. This switch is mounted on top of the tank and is testable.

TSSA assesses that there is likely to be no environmental impact should this variance be granted.
