13. In Appendix B to Sec. 172.101, paragraphs 1. and 2. would be
revised and the List of Marine Pollutants would be amended by removing
73 entries, adding 2 entries and revising 2 entries in appropriate
alphabetical order to read as follows:
Appendix B to Sec. 172.101--List of Marine Pollutants
1. See Sec. 171.4 of this subchapter for applicability of marine
pollutants. This appendix lists potential marine pollutants as
defined in Sec. 171.8 of this subchapter.
2. Marine pollutants listed in this appendix are not necessarily
listed by name in the Sec. 172.101 Table. If a marine pollutant not
listed by name or by synonym in the Sec. 172.101 Table meets the
definition of any hazard Class 1 through 8, then you must determine
the class and division of the material in accordance with
Sec. 173.2a of this subchapter. You must also select the most
appropriate hazardous material description and proper shipping name.
If a marine pollutant not listed by name or by synonym in the
Sec. 172.101 Table does not meet the definition of any Class 1
through 8, then you must offer it for transportation under the most
appropriate of the following two Class 9 entries: ``Environmentally
hazardous substances, liquid, n.o.s.,'' UN3082, or ``Environmentally
hazardous substances, solid, n.o.s.,'' UN3077.

or backing materials, that are present in transport, must not be
able to propagate a detonation as tested by one of the tests
described in the UN Manual of Tests and Criteria, Part I, Test
series 1(a). On the basis of the results of suitable burning rate
tests, and taking into account the standard tests in the UN Manual
of Tests and Criteria, Part III, subsection 33.2.1, nitrocellulose
membrane filters in the form in which they are to be transported
that do not meet the criteria for a Division 4.1 material are not
subject to the requirements of this subchapter. Packagings must be
so constructed that explosion is not possible by reason of increased
internal pressure. Nitrocellulose membrane filters covered by this
entry, each with a mass not exceeding 0.5 g, are not subject to the
requirements of this subchapter when contained individually in an
article or a sealed packet.

(7) ``T'' codes. (i) These provisions apply to the transportation
of UN portable tanks. Portable tank instructions specify the
requirements applicable to a portable tank when used for the
transportation of a specific hazardous material. These requirements
must be met in addition to the design and construction specifications
in part 178 of this subchapter. Portable tank instructions T1 through
T22 specify the applicable minimum test pressure, the minimum shell
thickness (in reference steel), bottom opening requirements and
pressure relief requirements. In T23, the organic peroxides and self-
reactive substances which are authorized to be transported in portable
tanks are listed along with the applicable control and emergency
temperatures. Liquefied compressed gases are assigned to portable tank
instruction T50. T50 provides the maximum allowable working pressures,
bottom opening requirements, pressure relief requirements and degree of
filling requirements for liquefied compressed gases permitted for
transport in portable tanks. Refrigerated liquefied gases which are
authorized to be transported in portable tanks are specified in tank
instruction T75.
(ii) The following table specifies the portable tank requirements
applicable to T Codes T1 through T22. Column 1 specifies the T Code.
Column 2 specifies the minimum test pressure, in bar (1 bar = 14.5
psig), at which the periodic hydrostatic testing required by
Sec. 173.32b of this subchapter must be conducted. Column 3 specifies
the section reference for minimum shell thickness or, alternatively,
the minimum shell thickness value. Column 4 specifies the applicability
of Sec. 178.275(f)(3) of this subchapter for the pressure relief
devices. When the word ``Normal'' is indicated, Sec. 178.275(f)(3) of
this subchapter does not apply. Column 5 either references the
applicable requirements for bottom openings in part 178 of this
subchapter, or references ``Prohibited'' which means bottom openings
are prohibited. The table follows:

[GRAPHIC] [TIFF OMITTED] TP23OC00.001
TP3 a. For liquids transported under elevated temperature, the
maximum degree of filling is determined by the following:
[GRAPHIC] [TIFF OMITTED] TP23OC00.002
Where: is the mean coefficient of cubical expansion of
the liquid between the mean temperature of the liquid during filling
(tf) and the maximum mean bulk temperature during
transportation (tr) both in degrees celsius.
b. For liquids transported under ambient conditions
may be calculated using the formula:
[GRAPHIC] [TIFF OMITTED] TP23OC00.003
Where: d15 and d50 are the densities of
the liquid at 15 deg.C (59 deg.F) and 50 deg.C (122 deg.F),
respectively.
TP4 The maximum degree of filling for portable tanks must not
exceed 90%.
TP5 [Reserved.]
TP6 To prevent the tank from bursting in an event, including fire
engulfment under the conditions prescribed in CGA pamphlet S-1.2
(see Sec. 171.7 of this subchapter), it must be equipped with
pressure relief devices that are adequate in relation to the
capacity of the tank and the nature of the hazardous material
transported.
TP7 The vapor space must be purged of air by nitrogen or other

thermal insulation of the tank.
TP18 The temperature of this material must be maintained between 18
deg.C (64.4 deg.F) and 40 deg.C (104 deg.F) while in
transportation. Portable tanks containing solidified methacrylic
acid must not be reheated during transportation.
TP19 The calculated wall thickness must be increased by 3 mm at the
time of construction. Wall thickness must be verified ultrasonically
at intervals midway between periodic hydraulic tests (every 2.5
years). The portable tank must not be used if the wall thickness is
less than that prescribed by the applicable T code in Column (7) of
the Table for this material.
TP20 This hazardous material must only be transported in insulated
tanks under a nitrogen blanket.
TP21 The wall thickness must not be less than 8 mm. Tanks must be
hydraulically tested and internally inspected at intervals not
exceeding 2.5 years.
TP22 Lubricants for portable tank fittings must be oxygen
compatible.
TP24 The portable tank may be fitted with a device to prevent the
build up of excess pressure due to the slow decomposition of the
hazardous material being transported. The device must be in the
vapor space when the tank is filled under maximum filling
conditions. This device must also prevent an unacceptable amount of
leakage of liquid in the case of overturning.
TP25 Sulphur trioxide 99.95% pure and above may be transported in
tanks without an inhibitor provided that it is maintained at a
temperature equal to or above 32.5 deg.C (90.5 deg.F).

25. Section 173.32 would be revised to read as follows:
Sec. 173.32 Requirements for the use of portable tanks.
(a) General requirements. No person may offer a hazardous material
for transportation in a portable tank except as authorized by this
subchapter.
(1) Except as otherwise provided in this subpart, a portable tank
may not be used for the transportation of a hazardous material unless
it meets the requirements of this subchapter.
(2) No person may fill and offer for transportation a portable tank
when the prescribed periodic test or inspection under subpart G of part
180 of this subchapter has become due until the test or inspection has
been successfully completed. This requirement does not apply to any
portable tank filled prior to the test or inspection due date.
(3) When a portable tank is used as a cargo tank container, it
shall conform to all the requirements prescribed for cargo tank
containers. (See Sec. 173.33.)
(b) Substitute packagings. A particular Specification portable tank
may be substituted for another portable tank as follows:
(1) An IM or UN portable tank may be used whenever an IM or UN
portable tank having less stringent requirements is authorized provided
the portable tank meets or exceeds the requirements for pressure-relief
devices, bottom outlets and any other special provisions specified in
Sec. 172.102(c)(7)(vi) of this subchapter.
(2) Where a Specification IM101 or IM102 portable tank is
prescribed, a Specification 51 portable tank otherwise conforming to
the special commodity requirements of Sec. 172.102(c)(7) of this
subchapter may be used.
(3) A DOT Specification 51 portable tank may be used whenever a DOT
Specification 56, 57, or 60 portable tank is authorized. A DOT
Specification 60 portable tank may be used whenever a DOT Specification
56 or 57 portable tank is authorized. A higher integrity tank used
instead of a specified portable tank must meet the same design profile;
for example, a DOT Specification 51 portable tank must be lined if used
instead of a lined DOT Specification 60 portable tank.
(c) Grandfather provisions for portable tanks--(1) Continued use of
specification 56 and 57 portable tanks. Continued use of an existing
portable tank constructed to DOT Specification 56 or 57 is authorized
only for a tank constructed before October 1, 1996. A stainless steel
portable tank internally lined with polyethylene that was constructed
on or before October 1, 1996, and that meets all requirements of DOT
Specification 57 except for being equipped with a polypropylene
discharge ball valve and polypropylene secondary discharge opening
closure, may be marked as a Specification 57 portable tank and used in
accordance with the provisions of this section.
(2) A DOT Specification 51 and IM 101 or IM 102 portable tank may
not be manufactured after January 1, 2003 may continue to be used for
the transportation of a hazardous material provided they fulfill the
requirements of
[[Page 63411]]
this subchapter, including the specification requirements and the
requirements of this subchapter for the transportation of the
particular hazardous material (see Sec. 171.14(d)(5) of this
subchapter), and provided it conforms to the periodic inspection and
tests specified for the particular portable tank in subpart G of part
180 of this subchapter. On and after January 1, 2003, all newly
manufactured portable tanks must conform to the requirements for the
design, construction and approval of UN portable tanks as specified in
Secs. 178.273, 178.274, 178.275, 178.276 and 178.277 of this
subchapter.
(3) A DOT Specification portable tank manufactured prior to January
1, 1992 that is equipped with a non-reclosable pressure relief device
may continue in service for the hazardous materials for which it is
authorized. Except for a DOT Specification 56 or 57 portable tank, a
DOT Specification portable tank manufactured after January 1, 1992,
used for materials meeting the definition for Division 6.1 liquids,
Packing Group I or II, Class 2 gases, or Class 3 or 4 liquids, must be
equipped with a re-closing pressure relief valve having adequately
sized venting capacity.
(d) Maximum Allowable Working Pressure. (1) Prior to filling and
offering a portable tank for transportation, the shipper must confirm
that the portable tank conforms to the specification required for the
hazardous material and that the maximum allowable working pressure
(MAWP) of the portable tank is greater than or equal to the highest
pressure obtained under the following conditions:
(i) For compressed gases and certain refrigerated liquids that are
not cryogenic liquids and that are not transported in a UN portable
tank, the pressure prescribed in Sec. 173.315. For liquefied compressed
gases transported in a UN portable tank, the pressures prescribed in
T50 in Sec. 172.102 of this subchapter.
(ii) For liquid hazardous materials the pressures specified in
Sec. 178.275(a) of this subchapter used for determining the MAWP.
(iii) The maximum pressure used to load or unload the hazardous
material.
(2) Unless otherwise specified, where a portable tank is
authorized, the minimum tank design pressure is 172 kPa (25 psig) for
any Packing Group I or Packing Group II liquid hazardous material that
meets more than one hazard class definition.
(e) External inspection prior to filling. Each portable tank must
be given a complete external inspection. Any unsafe condition must be
corrected prior to its being offered for transportation. The external
inspection shall include a visual inspection of:
(1) The shell, piping, valves and other appurtenances for corroded
areas, dents, defects in welds and other defects such as missing,
damaged, or leaking gaskets;
(2) All flanged connections or blank flanges for missing or loose
nuts and bolts;
(3) All emergency devices for corrosion, distortion, or any damage
or defect that could prevent their normal operation;
(4) All required markings on the tank for legibility; and
(5) Any device for tightening manhole covers to ensure such devices
are operative and adequate to prevent leakage at the manhole cover.
(f) Loading requirements. (1) A hazardous material may not be
loaded in a portable tank if the part of the tank or any of its
appurtenances having contact with the material during transportation
would be damaged, would cause a dangerous reaction with the material or
would compromise the ability of the portable tank to retain the
hazardous material.
(2) A hazardous material may not be loaded in a portable tank
unless it has pressure relief devices providing total relieving
capacity meeting the requirements of this subchapter.
(3) Except during a hydrostatic test, a portable tank may not be
subjected to a pressure greater than its maximum allowable working
pressure.
(4) A portable tank may not be loaded to a gross weight greater
than the maximum allowable gross weight specified on its identification
plate.
(5) Except for a non-flowable solid or a liquid with a viscosity of
2,680 centistokes (millimeters squared per second) or greater at
20 deg.C (68 deg.F), a portable tank or compartment thereof having a
volume greater than 7,500 L (1,980 gallons) may not be loaded to a
filling density of more than 20% and less than 80% by volume. This
filling restriction does not apply if a portable tank is divided by
partitions or surge plates into compartments of not more than 7,500 L
(1,980) capacity. Portable tanks must not be offered for transportation
in an ullage condition liable to produce an unacceptable hydraulic
force due to surge.
(6) The outage for a portable tank may not be less than 2% at a
temperature of 50 deg.C (122 deg.F). For UN portable tanks, the
applicable maximum filling limits apply as specified according to the
assigned TP codes in Column (7) of the Sec. 172.101 Table of this
subchapter except when transported domestically.
(7) Each tell-tale indicator for the space between a frangible disc
and a safety relief valve mounted in series must be checked after the
tank is filled and prior to transportation to ensure that the frangible
disc is leak free. Any leakage through the frangible disc must be
corrected prior to offering the tank for transportation. The tell-tale
device must be designed to prevent the loss of any hazardous material
through the device itself while the tank is in transportation.
(8) During filling, the temperature of the hazardous materials
shall not exceed the limits of the design temperature range of the
portable tank.
(9) The maximum mass of liquefied compressed gas per liter (gallon)
of shell capacity (kg/L or lbs./gal.) may not exceed the density of the
liquefied compressed gas at 50 deg.C (122 deg.F). The portable tank
must not be liquid full at 60 deg.C (140 deg.F).
(g) Relief system. Any DOT Specification portable tank manufactured
prior to January 1, 1992 that is equipped with a non-reclosable
pressure relief device may continue in service for the hazardous
materials for which it it is authorized. Except for DOT Specification
56 and 57 portable tanks, any DOT Specification portable tank
manufactured after January 1, 1992 used for materials meeting the
definition for Division 6.1 liquids Packing Group I or II, Class 2
gases, or Class 3 or 4 liquids must be equipped with a reclosing
pressure relief valve having adequately sized venting capacity.
(h) Additional requirements for specific modal transport. In
addition to other applicable requirements, the following apply:
(1) A portable tank containing a hazardous material may not be
loaded on a highway or rail transport vehicle unless loaded entirely
within the horizontal outline thereof, without overhang or projection
of any part of the tank assembly. In addition, for unloading a portable
tank, see Sec. 177.834(h) of this subchapter.
(2) A portable tank used for the transportation of flammable
liquids by rail may not be fitted with non-reclosing pressure relief
devices except in series with reclosing pressure relief valves.
(3) A portable tank or Specification 106A or 110A multi-unit tank
car containing a hazardous material may not be offered for
transportation aboard a passenger vessel unless:
(i) The vessel is operating under a change to its character of
vessel certification as defined in Sec. 171.8 of this subchapter; and
[[Page 63412]]
(ii) The material is permitted to be transported aboard a passenger
vessel in the Sec. 172.101 Table of this subchapter.
(i) Additional general commodity specific requirements. In addition
to other applicable requirements, the following requirements apply:
(1) Each uninsulated portable tank used for the transportation of
liquefied compressed gases must have an exterior surface finish that is
significantly reflective, such as a light-reflecting color if painted,
or a bright reflective metal or other material if unpainted.
(2) If a hazardous material is being transported in a molten state,
the portable tank must be thermally insulated with suitable insulation
material of sufficient thickness that the overall thermal conductance
is not more than 0.080 Btu per hour per square foot per degree
Fahrenheit differential.
(j) Additional requirements for portable tanks other than IM
specification and UN portable tanks. (1) The bursting strength of any
piping and fittings must be at least four times the design pressure of
the tank, and at least four times the pressure to which, in any
instance, it may be subjected in service by the action of a pump or
other device (not including safety relief valves) that may subject
piping to pressures greater than the design pressure of the tank.
(2) Pipe joints must be threaded, welded or flanged. If threaded
pipe is used, the pipe and pipe fittings must not be lighter than
(Schedule 80) weight. Non-malleable metals must not be used in the
construction of valves or fittings. Where copper tubing is permitted,
joints must be brazed or be of equally strong metal union type. The
melting point of brazing material may not be lower than 1,000 deg.F
(537.8 deg.C). The method of joining tubing must not decrease the
strength of the tubing such as by the cutting of threads.
(3) Non-malleable metals may not be used in the construction of
valves or fittings.
(4) Suitable provision must be made in every case to allow for
expansion, contraction, jarring and vibration of all pipe. Slip joints
may not be used for this purpose.
(5) Piping and fittings must be grouped in the smallest practicable
space and must be protected from damage as required by the
specification.
(6) All piping, valves and fittings on every portable tank must be
leakage tested with gas or air after installation and proved tight at
not less than the design pressure of the portable tank on which they
are used. In the event of replacement, all such piping, valves, or
fittings so replaced must be tested in accordance with the requirements
of this section before the portable tank is returned to transportation
service. The requirements of this section apply to all hoses used on
portable tanks, except that hoses may be tested either before or after
installation on the portable tank.
(7) All materials used in the construction of portable tanks and
their appurtenances may not be subject to destructive attack by the
contents of the tank.
(8) All parts of the portable tanks and appurtenances for anhydrous
ammonia must be steel. No aluminum, copper, silver, zinc, nor their
alloys may be used. Brazed joints may not be used.
(9) Each outlet of a portable tank used for the transportation of
liquefied compressed gases, except carbon dioxide, must be provided
with a suitable automatic excess-flow valve (see definition in
Sec. 178.337-1(g) of this subchapter). These valves must be located
inside the portable tank or at a point outside the portable tank where
the line enters or leaves the portable tank. The valve seat must be
located inside the portable tank or may be located within a welded
flange or its companion flange, or within a nozzle or within a
coupling. The installation must be made in such a manner as to
reasonably assure that any undue strain which causes failure requiring
functioning of the valve shall cause failure in such a manner that it
will not impair the operation of the valve.
(i) Safety device connections and liquid level gauging devices that
are constructed so that the outward flow of tank contents willl not
exceed that passed by an opening of 0.1397 cm (0.0550 inches) are not
required to be equipped with excess-flow valves.
(ii) An excess-flow valve must close automatically if the flow
reaches the rated flow of gas or liquid specified by the original valve
manufacturer when piping mounted directly on the valve is sheared off
before the first valve, pump, or fitting downstream from the excess
flow valve.
(iii) An excess-flow valve may be designed with a by-pass, not to
exceed a 0.1016 cm (0.040 inches) diameter opening to allow
equalization of pressure.
(iv) Filling and discharge lines must be provided with manually
operated shut-off valves located as close to the tank as practical. The
use of ``Stop-Check'' valves to satisfy with one valve the requirements
of this section is forbidden.
(10) Each portable tank used for carbon dioxide and nitrous oxide
must be lagged with a suitable insulation material of such thickness
that the overall thermal conductance is not more than 0.08 Btu per
square foot per degree Fahrenheit differential in temperature per hour.
The conductance must be determined at 60 deg. Fahrenheit. Insulation
material used on portable tanks for nitrous oxide must be
noncombustible.
(11) A refrigerating and/or heating coil or coils must be installed
in portable tanks used for carbon dioxide and nitrous oxide. Such coils
must be tested externally to at least the same pressure as the test
pressure of the portable tank. The coils must also be tested internally
to at least twice the working pressure of the heating or refrigerating
system to be used, but in no case less than the test pressure of the
portable tank. Such coils must be securely anchored. The refrigerant or
heating medium to be circulated through the coil or coils must be such
as to cause no adverse chemical reaction with the portable tank or its
contents in the event of leakage.
