Intent 1:
To exempt pier storage tanks from the application
of Sentence 4.6.6.5.(1), which would otherwise require the
tanks to be located on the shore or a solid-fill type pier, if certain
measures are taken.
These measures are to limit
the probability that the escape of liquid from the tanks:
- will spread beyond the tank area, which could lead to
the ignition of vapour from a nearby ignition source, which could
lead to damage to the building or facility, and
- will be in such large quantities that it cannot be controlled
by emergency responders, which could lead to the spread of fire, which
could lead to damage to the building or facility.
