AWARENESS MEMORANDUM

Purpose: To provide information as a reminder about alarms and warning signals in the Marcus Hook berthing areas to all who transit past Marcus Hook Industrial Complex including but not limited to, Pilots, tug/barge companies, assist tug companies, and the marine community through the Mariners Advisory Committee.

Objective: Thankfully there has not been an emergency in quite some time and as a result certain warning signals may be misconstrued when those who transit the river are not reminded from time to time. Basically the objective is safety awareness. Please give a wide berth or avoid the area altogether if the warning signal is seen/heard as much as safe navigation will allow. Note: testing before each vessel arrival at MHIC will only be approximately 30 seconds.

(a) Each marine transfer area for LHG must have a rotating or flashing amber light that is visible for at least 1,600 meters (1 mile) from the transfer connection in all directions.
(b) Each marine transfer area for LHG must also have a siren that is audible for at least 1,600 meters (1 mile) from the transfer connection in all directions.
(c) Each light and siren required by this section must be located so as to minimize obstructions.
