protection system meets the requirements as
specified in Section 8.6 and report in writing
to the authority having jurisdiction the
measured voltage potential(s) and whether
or not cathodic protection has been achieved.
4.5.3(1) A new steel storage tank added to an existing
system that already has an impressed current
cathodic protection system shall:
(a) be in conformance with CAN/ULC-
S603-1992, “Underground Steel Tanks”;
and
(b) be electrically bonded into the impressed
current cathodic protection system. (See
Appendix B, note B.4.5.3(1)(b))
4.5.3(2) When a new storage tank built in
conformance with CAN/ULC-S603.1-1992,
“Galvanic Corrosion Protection Systems for
Underground Steel Tanks” is installed near
an existing CAN/ULC S603.1-1992,
“Galvanic Corrosion Protection Systems for
Underground Steel Tanks” storage tank,
precautions shall be taken to ensure both the
new and existing tanks are adequately
protected. (See Appendix B, note B.4.5.3(2))
4.5.4(1) Impressed current cathodic protection shall
be interlocked in such a manner that if the
cathodic-protection system is turned off or
bypassed either:
(a) power to the pump will be shut off; or
(b) audible and visual alarms will be
turned on.
4.5.5 Impressed current cathodic-protection
systems shall be equipped with a running
time or a downtime totalizer. (See Appendix
B, note B.4.5.5)
4.5.6(1) Cathodically protected storage tanks shall be
installed with:
(a) test wires brought to the surface and
fastened at an accessible location; or
(b) a permanent reference electrode and
approved monitoring station, including
test wires for each tank.
