(b) an overfill protection device;
(c) a fill pipe spill containment device;
(d) containment sumps, as applicable;
(e) leak detection in conformance with
Part 6;
(f) except for venting purposes, liquid-
and vapour-tight connections, caps
and adapters; and
(g) corrosion protection, as applicable.
4.2.4(2) An underground storage tank system for
storing used oil shall be designed and
installed to have:
(a) double-wall tank(s) with monitorable

for product removal that can be removed
for the purpose of clearing a blockage;
(d) product removal or transfer connections
located within a spill containment device;
(e) an overfill protection device where the
storage tank is filled by pump or remote
manual fill;
(f) where the fill port is outside, it shall
be fitted with a spill containment device
having a capacity of at least 25 L and
the spill containment device shall be fitted
with:
(i) a rain cover; and
(ii) a screen to prevent nuts, bolts, rags,
and other such objects from entering
the storage tank;
(g) in-take venting with an open area at least
twice the open area of the suction pipe as
specified in 4.2.4(2)(c) to avoid vacuum
collapse from high rate of product
removal; and
(h) leak detection in conformance with
Part 6.
4.2.5 A company or individual that is authorized
