Current through Register Vol. 48, No. 28, July 12, 2024
a) If
				it is found necessary to dispose of anhydrous ammonia, it shall be discharged
				into a vessel containing water sufficient to absorb it. Sufficient water shall
				be at least ten parts of water per one part anhydrous ammonia. The anhydrous
				ammonia shall be injected into the water as near the bottom of the vessel as
				practical. Provision must be made to prevent bleeding of transport and railroad
				tank car liquid lines or hoses into the atmosphere when disconnecting. This
				shall be done through the use of a wet hose with a shutoff valve at each end of
				the hose, by bleeding into water at no greater rate than one gallon of
				anhydrous ammonia to 10 gallons of ammonia-free water to prevent discharge of
				fumes into the atmosphere, or with a recovery system.
b) A certified competent attendant shall
				supervise the transfer of liquids from the time the connections are first made
				until the railroad tank car is finally disconnected or the transport truck is
				completely unloaded and finally disconnected. Any time the site is unattended,
				the railroad tank car shall not be connected to the unloading riser. During the
				transfer operations of the transport, chock blocks shall be so placed as to
				prevent rolling of the vehicle.
c)
				Containers shall be filled or used only upon authorization of owners.
d) Containers shall be gauged and charged
				only in the open air or in a building especially provided for that
				purpose.
e) Pumps used for
				transferring anhydrous ammonia shall be recommended for anhydrous ammonia
				service by the manufacturer or documented for such service by the
				owner/operator using recognized and accepted good engineering methods.
1) Liquid pumps may be piston, rotary,
				centrifugal or regenerative type for 250 psig working pressure.
2) Positive displacement pumps shall be
				equipped with a pressure actuated by-pass valve on the discharge side of the
				pump. This valve shall operate to limit the pressure developed by the pump to
				the maximum for which the pump is rated. Piping or tubing sized to carry the
				full capacity of the pump at the actuation pressure of this valve shall connect
				the discharge of this valve with the container from which ammonia is being
				pumped. If this line is capable of being closed off by a valve, an additional
				by-pass device shall be incorporated in the pump to by-pass back to the suction
				port. The pressure actuated by-pass valve and the return piping or tubing shall
				be installed in accordance with the pump manufacturer's recommendations or
				documented for such service by the owner/operator using recognized and
				generally accepted good engineering methods.
3) A pressure gauge graduated from at least 0
				to 400 psig shall be installed before the relief valve line on the discharge
				side of the pump.
4) Centrifugal or
				regenerative pumps do not require a bypass valve, but the installation shall
				incorporate a line from the discharge side of the pump to the vapor space of
				the supplying tank and a shutoff valve shall be installed in this
				line.
