(2) The unaffected storage assembly is being used with a distribution point.
(3) To temporarily adapt TWDS operation, proceed as follows:
(a) Close gate valve connected to defective storage tank.
(b) If distribution point is being used with defective storage tank, shut down distribution point (para. 2-13).
Shutdown engine on 125 GPM pump (refer to applicable technical manual).
(c) Notify operators at other stations of equipment failure. Pumps may require adjustment.
d. Failure of Distribution Point. If a distribution point fails, TWDS operation is possible ONLY if two distribution points
