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 harm to persons, 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 harm to persons.
