GLENN BURNEY MARINA LTD - Approval for variance from the Liquid Fuels Handling Code

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

5.5.4. At a marina, every product dispenser shall be firmly installed on shore, or on a

stationary dock, wharf, or pier.

Why the Code Would Not be Met

A stationary dock is not feasible in this location due to the depth of the water.

Safety Assessment

A pipe attached to a dock must be suitable for aboveground installation. Rigid steel piping was the only type of pipe that was suitable for aboveground installation in the past.  Dispensers were prohibited on floating docks since the wave action could stress the pipe and possibly cause it to fail.

The installation drawings and the risk and safety management plan are approved by a professional engineer.

The proposed installation comprises a floating fuel service dock which will house two gasoline dispensers. The fuel service dock will be connected to the shoreline via a 105-metre-long main dock.  

Horizontal movement will be restricted by anchors fixed to the dock.

Secondary chains will be used to restrain dock movement in addition to the primary dock connections.

DoubleTrac by Omega Flex piping will be used to convey the fuel from the shore along the length of the main dock to the two dispensers on the dock.

DoubleTrac pipe is a flexible double-wall pipe that has been certified by the Underwriters’ Laboratories of Canada (ULC) for both aboveground and underground installation and acceptable for floating dock installations.

DoubleTrac piping is vacuum monitored. A pipe failure in either the primary or secondary pipe will result in a loss of vacuum.

A breakaway fitting will be in place at the shoreline end of the main pipe which will fail closed in the event of a pipe separation.

Emergency stop will be located near dispensers.

Under-dispenser sumps will be equipped with leak sensors.

Dispensers will be equipped with shear valves.

The floating dock components will be inspected weekly during the operating season (May - September) and monthly during the off-season (October - April). The inspection routine is as follows:

• Inspect the vacuum gauge at both ends of the DoubleTrac piping. If either gauge reads below -12 in Hg, close the shut-off valve at the shore;
  • • In the off-season, the shut-off valve at the shore should remain closed at all times when not in use;
• Visually inspect the hinge connections between the main dock and the fuel service dock;
• Visually inspect the hinge connections between the main dock and the shoreline;
• Visually inspect the under-dispenser sumps on the fuel service dock for any build up of fluid or damage to the sump wall.

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