(d) The regulations in this part have preemptive impact over State
law on the same subject. The Coast Guard has determined, after
considering the factors developed by the Supreme Court in U.S. v.
Locke, 529 U.S. 89 (2000), that in directing the Secretary to regulate
the safe transportation of hazardous material and the safety of
individuals and property on board vessels subject to inspection, as
well as the provision of loading information, Congress intended to
preempt the field of safety standards for solid materials requiring
special handling when transported in bulk on vessels.

Sec.  148.2  Responsibility and compliance.

    Each master of a vessel, person in charge of a barge, owner,
operator, shipper, charterer, or agent must ensure compliance with this
part. These persons are also responsible for communicating requirements
to every person performing any function covered by this part.

Sec.  148.3  Definitions.

    As used in this part--
    A-60 class division means a division as defined in Sec.  32.57-5 of
this chapter.
    Adjacent space means any enclosed space on a vessel, such as a
cargo hold, cargo compartment, accommodation space, working space,
storeroom, passageway, or tunnel, that shares a common bulkhead or deck
with a hatch, door, scuttle, cable fitting or other penetration, with a
cargo hold or compartment containing a material listed in Table 148.10
of this part.

owner or operator of a barge to have charge of the barge.
    Potentially dangerous material or PDM means a material that does
not fall into a particular hazard class but can present a danger when
carried in bulk aboard a vessel. The dangers often result from the
material's tendency to self-heat or cause oxygen depletion. Materials
that present a potential danger due solely to their tendency to shift
in the cargo hold are not PDMs. For international shipments prepared in
accordance with the IMSBC Code (incorporated by reference, see Sec.
148.8), equivalent terminology to PDM is Material Hazardous only in
Bulk (MHB).
    Readily combustible material means a material that may not be a

(0.984 long tons) of a bulk solid material.
    Threshold limit value or TLV means the time-weighted average
concentration of a material that the average worker can be exposed to
over a normal eight-hour working day, day after day, without adverse
effect. This is a trademark term of the American Conference of
Governmental Industrial Hygienists (ACGIH).
    Transported includes the various operations associated with cargo
transportation, such as loading, off-loading, handling, stowing,
carrying, and conveying.
    Trimming means any leveling of a cargo within a cargo hold or
compartment, either partial or total.
    Tripartite agreement means an agreement between the national
administrations of the port of loading, the port of discharge, and the
flag state of the vessel, on the conditions of carriage of a cargo.

the Coast Guard that the requirement is impracticable or unnecessary
and that an equivalent level of safety can be maintained.
    (b) Each request for authorization of an alternative procedure
must--
    (1) Be in writing;
    (2) Name the requirement for which the alternative is requested;
and
    (3) Contain a detailed explanation of--
    (i) Why the requirement is impractical or unnecessary; and

removed before a material required to be separated from it is loaded.
    (c) Definitions and application of segregation terms:
    (1) ``Separated from'' means located in different cargo
compartments or holds when stowed under deck. If the intervening deck
is resistant to fire and

liquid, a vertical separation, i.e., in different cargo compartments,
is acceptable as equivalent to this segregation.
    (2) ``Separated by a complete cargo compartment or hold from''
means either a vertical or horizontal separation, for example, by a
complete cargo compartment or hold. If the intervening decks are not
resistant to fire and liquid, only horizontal separation is acceptable.
    (3) ``Separated longitudinally by an intervening complete cargo
compartment or hold from'' means that vertical separation alone does
not meet this requirement.

combustible material, including the residue of previous cargoes if
other than coal.
    (c) The master of each vessel carrying coal must ensure that--
    (1) All openings to the cargo hold, except for unloading gates on
self-unloading vessels, are sealed before loading the coal and, unless
the coal is as described in paragraph (f) of this section, the hatches
must also be sealed after loading;
    (2) As far as practical, gases emitted by the coal do not
accumulate in enclosed working spaces such as storerooms, shops, or
passageways, and tunnel spaces on self-unloading vessels, and that such
spaces are adequately ventilated;

explosive gas atmosphere. The master of the vessel must ensure that the
affected equipment and cables remain de-energized as long as this coal
remains in the hold.
    (h) For all coal loaded on a vessel, other than an unmanned barge,
the atmosphere above the coal must be routinely tested for the presence
of methane, carbon monoxide, and oxygen, following the procedures in
the Appendices to the schedules for Coal and Brown Coal Briquettes as
contained in the IMSBC Code (incorporated by reference, see Sec.
148.8). This testing must be performed in such a way that the cargo
hatches are not opened and entry into the hold is not necessary.
    (i) When carrying a coal described in paragraph (e) of this
section, the atmosphere above the coal must be monitored for the
presence of carbon

monoxide as prescribed in paragraph (h) of this section. The results of
this monitoring must be recorded at least twice in every 24-hour
period, unless the conditions of paragraph (m) of this section are met.
If the level of carbon monoxide is increasing rapidly or reaches 20
percent of the lower flammability limit (LFL), the frequency of
monitoring must be increased.
    (j) When a cargo of coal has a potential to self-heat or has been
observed to be heating, the hatches should be closed and sealed and all
surface ventilation halted except as necessary to remove any methane
that may have accumulated.
    (k) If the level of carbon monoxide monitored under paragraph (i)
of this section continues to increase rapidly or the temperature of
coal carried on board a vessel exceeds 55 [deg]C (131 [deg]F) and is
increasing rapidly, the master must notify the nearest Coast Guard
Captain of the Port of--
    (1) The name, nationality, and position of the vessel;
    (2) The most recent temperature, if measured, and levels of carbon
monoxide and methane;

coal;
    (4) The last port of call of the vessel and its next port of call;
and
    (5) What action has been taken.
    (l) If the level of methane as monitored under paragraph (h) of
this section reaches 20 percent of the LFL or is increasing rapidly,
ventilation of the cargo hold, under paragraph (f) of this section,
must be initiated. If this ventilation is provided by opening the cargo
hatches, care must be taken to avoid generating sparks.
    (m) The frequency of monitoring required by paragraph (l) of this
section may be reduced at the discretion of the master provided that--
    (1) The level of gas measured is less than 20 percent of the LFL;
    (2) The level of gas measured has remained steady or decreased over
three consecutive readings, or has increased by less than 5 percent
over four consecutive readings spanning at least 48 hours; and
    (3) Monitoring continues at intervals sufficient to determine that
the level of gas remains within the parameters of paragraphs (n)(1) and
(n)(2) of this section.

    (h) Temperature readings of the seed cake must be taken at least
once in every 24-hour period. If the temperature exceeds 55 [deg]C (131
[deg]F) and continues to increase, ventilation to the cargo hold must
be discontinued. If heating continues after ventilation has been
discontinued, carbon dioxide or the inert gas required under paragraph
(g) of this section must be introduced into the hold. If the seed cake
is solvent-extracted, the use of inert gas must not be introduced until
fire is apparent, to avoid the possibility of igniting the solvent
vapors by the generation of static electricity.
    (i) Seed cake must be carried under the terms of a Special Permit
issued by the Commandant (CG-5223) per subpart B of this part if--
    (1) The oil was mechanically expelled; and
    (2) It contains more than 10 percent vegetable oil or more than 20
percent vegetable oil and moisture combined.

Sec.  148.315  Sulfur.

    (a) This part applies to lump or coarse grain powder sulfur only.
Fine-grained powder (``flowers of sulfur'') may not be transported in
bulk.
    (b) After the loading or unloading of lump or coarse grain powder
sulfur has been completed, sulfur dust must be removed from the
vessel's decks, bulkheads, and overheads. Cargo residues and deck
sweepings must be disposed of pursuant to 33 CFR parts 151.55 through
151.77.
    (c) A cargo space that contains sulfur or the residue of a sulfur
cargo must be adequately ventilated, preferably by mechanical means.
Each ventilator intake must be fitted with a spark-arresting screen.

Sec.  148.320  Tankage; garbage tankage; rough ammonia tankage; or
tankage fertilizer.

    (a) This part applies to rough ammonia tankage in bulk that
contains 7 percent or more moisture by weight, and garbage tankage and
tankage fertilizer that contains 8 percent or more moisture by weight.
    (b) Tankage to which this part applies may not be loaded in bulk if
its temperature exceeds 38 [deg]C (100 [deg]F).
    (c) During the voyage, the temperature of the tankage must be
monitored often enough to detect spontaneous heating.

Sec.  148.325  Wood chips; wood pellets; wood pulp pellets.

    (a) This part applies to wood chips and wood pulp pellets in bulk
that may oxidize, leading to depletion of oxygen and an increase in
carbon dioxide in the cargo hold.
    (b) No person may enter a cargo hold containing wood chips, wood
pellets, or wood pulp pellets, unless--
    (1) The atmosphere in the cargo hold has been tested and contains
enough oxygen to support life; or
    (2) The person entering the cargo hold is wearing the appropriate
self-contained breathing apparatus.

Sec.  148.330  Zinc ashes; zinc dross; zinc residues; zinc skimmings.

    (a) The shipper must inform the cognizant Coast Guard Captain of
the Port in advance of any cargo transfer operations involving zinc
ashes, zinc dross, zinc residues, or zinc skimmings (collectively,
``zinc material'') in bulk.
    (b) Zinc material must be aged by exposure to the elements for at
least one year before shipment in bulk.
    (c) Before loading in bulk, zinc material must be stored under
cover for a period of time to ensure that it is as dry as practical. No
zinc material that is wet may be accepted for shipment.
    (d) Zinc material may not be loaded in bulk if its temperature is
greater than 11.1 [deg]C (52 [deg]F) in excess of the ambient
temperature.
    (e) Paragraphs (e)(1) through (e)(5) of this section apply only
when zinc materials are carried by a cargo vessel:
    (1) Zinc material in bulk must be stowed in a mechanically
ventilated hold that--
    (i) Is designed for at least one complete air change every 30
minutes based on the empty hold;
    (ii) Has explosion-proof motors approved for use in Class I,
Division 1, Group B atmospheres or equivalent motors approved by the
vessel's flag state administration for use in hydrogen atmospheres; and
    (iii) Has nonsparking fans.
    (2) Combustible gas detectors capable of measuring hydrogen
concentrations of 0 to 4.1 percent by volume must be permanently
installed in holds that will carry zinc material. If the concentration
of hydrogen in the space above the cargo exceeds 1 percent by volume,
the ventilation system must be run until the concentration drops below
1 percent by volume.
    (3) Thermocouples must be installed approximately 6 inches below
the surface of the zinc material or in the space immediately above the
zinc material. If an increase in temperature is detected, the
mechanical ventilation system required by paragraph (d) of this section
must be used until the temperature of the zinc material is below 55
[deg]C (131 [deg]F).
    (4) Except as provided in paragraph (e)(5) of this section, the
cargo hatches of holds containing zinc material must remain sealed to
prevent the entry of seawater.
    (5) If the concentration of hydrogen is near 4.1 percent by volume
and increasing, despite ventilation, or the temperature of the zinc
material reaches 65 [deg]C (150 [deg]F), the cargo hatches should be
opened provided that weather and sea conditions are favorable. When
hatches are opened take care to prevent sparks and minimize the entry
of water.

to moisture migration and subsequent liquefaction if shipped with
moisture content in excess of the transportable moisture limit.
    (2) Moisture migration is the movement of moisture by settling and
consolidation of a material, which may result in the development of a
flow state in the material.
    (3) Transportable moisture limit or TML of a cargo that may liquefy
is the maximum moisture content that is considered safe for carriage on
vessels.
    (d) Except on a vessel that is specially constructed or specially
fitted for the purpose of carrying such cargoes (see also section 7 of
the IMSBC Code, incorporated by reference, see Sec.  148.8), a cargo
subject to liquefaction may not be transported by vessel if its
