(11) The bags must be blocked and
braced as necessary to prevent shifting
of the bagged cargo adjacent to any

(e) Notwithstanding § 176.83(b) of this
part, ammonium nitrate and ammonium nitrate fertilizers classed as Division 5.1 (oxidizers) materials, may be
stowed in the same hold, compartment,
magazine, or freight container with

(b) Any of the following may be loaded on or unloaded from a vessel at any
waterfront facility without a permit:
(1) Ammonium nitrate, Division 5.1
(oxidizer) UN1942, in a rigid packaging
with a noncombustible inside packaging.
(2) Ammonium nitrate fertilizer, Division 5.1 (oxidizer) UN 2067, if the
nearest COTP is notified at least 24
hours in advance of any loading or unloading in excess of 454 kg (1,000
pounds).
(3) Division 1.5 compatibility group D
material in a rigid packaging with noncombustible inside packaging.
(4) Ammonium nitrate fertilizer,
Class 9, UN 2071.
(c) Before a permit may be issued,
the following requirements must be
met in addition to any others the
COTP may impose:
(1) If the material is Explosives,
blasting, type E, Division 1.5 compatibility group D, UN0332 in a combustible packaging or in a rigid packaging
with a combustible inside packaging, it
must be loaded or unloaded at a facility remote from populous areas, or
high-value or high-hazard industrial facilities, so that in the event of fire or
explosion, loss of lives and property
may be minimized;
(2) If the material is a Division 1.5
compatibility group D material in a
non-rigid combustible packaging and
loaded in a freight container or transport vehicle, it may be loaded or unloaded at a non-isolated facility if the
facility is approved by the COTP;
(3) Each facility at which the material is to be loaded or unloaded must
conform with the requirements of the
port security and local regulations and
must have an abundance of water readily available for fire fighting and
(4) Each facility at which the material is to be loaded or unloaded must be
located so that each vessel to be loaded
or unloaded has an unrestricted passage to open water. Each vessel must
be moored bow to seaward, and must be
maintained in a mobile status during
loading, unloading, or handling operations by the presence of tugs or the
readiness of engines. Each vessel must
have two wire towing hawsers, each
having an eye splice, lowered to the

water’s edge, one at the bow and the
other at the stern.
