Table of Contents
Floating hydrocarbon-on-water detectors will be used to detect any hydrocarbon sheens that develop on
the surface of the remote containment reservoir or on the firewater reservoir. If hydrocarbons are
detected, they will be removed and disposed of in a controlled manner.
The sewer will include a holding tank and a biokinetic system.
4.16.2 Solid Waste
Solid waste will be collected and compacted and then trucked off site as required.
4.17 Pollution Prevention Systems and Equipment
As described in the following sections, various pollution prevention systems and equipment will be used
at Kitimat Terminal to prevent system leaks and allow for the containment, isolation, and recovery of any
hydrocarbons that may be released (Reference 17, 18). These systems are described in greater detail in
TERMPOL Study 3.18.
4.17.1 Containment Boom
Each tanker berth will be equipped with a containment boom designed to maintain containment of any
potential oil spills that may occur during oil loading operations. The boom will be anchored to the loading
platform and will be deployed after a tanker has moored and before loading operations begin. Each half of
the boom will be floated out from under the berth platform and towed by utility boats around either end of
the vessel. The ends will be connected together encircling the ship and berth completely.
For safety reasons, it is not recommended that the boom be deployed during the discharging (unloading)
of condensate. This product is more volatile and poses certain explosion risks if released into the water
and contained around the ship within the confines of a boom.
4.17.2 Uplands Tank Overflow Systems
The main tank lot and the recovered oil tank at the marine terminal will have containment berms around
them. The berm wall design will be determined in detailed engineering and will likely be constructed of
either engineered fill or vertical concrete wall system. The area will be designed to collect liquids and
direct them through a pipe system to the remote impoundment reservoir. The main tank lot will be gravity
fed to the impoundment reservoir. The recovered oil tank at the marine terminal will have a sump system
to deliver any liquids to the impoundment reservoir. The main tank lot berm system will be designed to
allow overflow between tank lots prior to overflow of the perimeter walls.
The tanks will be equipped with safeguards to prevent tank overflow. Each tank will have a level
transmitter that will alarm when the normal fill level of the tank is exceeded. If the tank level continues to
rise, a level switch will be activated that causes the tank’s fill manifold valves to close (2 valves per tank).
The valve manifold will incorporate check valves to limit the ability for material to drain from one tank to
another. All remaining piping capable of transferring oil and condensate between tanks will be equipped
with isolation valves connected to an uninterruptible power supply generator.
