Pump Controls. Where necessary, provide remote-
operated valves on storage tank inlet and outlet lines,
suction and discharge of transfer pumps, and transfer lines at
fuel piers and other locations. Operation of pump suction and
discharge valves may be a part of the automatic sequence for
the starting of a centrifugal pump and for shutting it down,
remotely, locally, or by a protective shutdown device.
Remote-operated valves can be either motor-operated or the
solenoid pilot-type, hydraulically operated diaphragm control
valves. Equip these valves with green and red (open and
closed) indicating lights at their pushbutton control
Provide the following controls:
a) A stop-lockout button at each remotely operated
pump for maintenance operation.
b) Indicator lights at the control station to give
positive indications both when a pump is operating and when it
is not energized. Use the "push-to-test" type.
c) A signal light or alarm to indicate pump failure
when a pump is controlled automatically.
d) Reduced voltage starting if required by electric
utility supplier or in all cases for pump motors greater than
e) Emergency fuel shut-off (EFSO) buttons with lock-
key reset at all pump locations and at the central supervisory
Transfer Pumps. Transfer pumps are used to supply
fuel to a tank truck loading facility, tank car loading
facility, or transfer fuel from one place on the installation
to another (e.g., bulk facility to ready issue tank). If
these pumps exceed 150 horsepower (112 kW), comply with
Paragraph 220.127.116.11 of this handbook. In addition to
requirements in Paragraph 18.104.22.168 of this handbook, provide
transfer pumps with push button start/stop stations. Where
these pumps are used for truck and/or car loading, provide
push button controls adjacent to the pumps and at each loading
