2013 Liquid Chemical Categorization Updates

AGENCY: Coast Guard, DHS.

ACTION: Supplemental notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard proposes additional updates and revisions to
regulatory tables that were amended by an interim rule published in
August 2013. The tables list liquid hazardous materials, liquefied
gases, and compressed gases approved for maritime transportation in
bulk, and indicate how each cargo is categorized by its pollution risk
and safe carriage requirements. These proposals would correct errors in
the interim rule and bring the tables current through December 2013.
Updated information is of value to shippers and to the owners and
operators of U.S.-flag tank and bulk cargo vessels in any waters, and
most foreign-flag tank and oceangoing bulk cargo vessels in U.S.
waters. The proposed rule promotes the Coast Guard's maritime safety
and stewardship (environmental protection) missions.

III. Discussion

    Basis and purpose. The legal basis of this rulemaking is 46 U.S.C.
3703, which requires the Secretary of the department in which the Coast
Guard is operating to prescribe regulations relating to the operation
of vessels that carry liquid bulk dangerous cargoes, and to the types
and grades of cargo those vessels carry. Additional regulatory
authority is provided by 33 U.S.C. 1903 (regulations to implement the
International Convention for the Prevention of Pollution from Ships,
1973, or ``MARPOL''), 46 U.S.C. 2103 (general merchant marine
regulatory authority), and 46 U.S.C. 3306 (regulations for the safety
of individuals and property on inspected vessels). The Secretary's
authority under these statutes is delegated to the Coast Guard in DHS
Delegation No. 0170.1, para.II (77), (92.a), and (92.b).
    The purpose of the rulemaking is to update and revise regulatory
tables that list liquid hazardous materials, liquefied gases, and
compressed gases that have been approved for maritime transportation in
bulk, and that indicate how each cargo is categorized by its pollution
risk and safe carriage requirements.
    2013 Interim Rule. The Coast Guard published an interim rule on
this topic in 2013.\2\ Acknowledging public comments that brought to
light certain errors in the interim rule, the Coast Guard delayed its
effective date, originally September 16, 2013, on three occasions, most
recently until January 16, 2017.\3\ We are correcting those errors

in this supplemental notice of proposed rulemaking (SNPRM). In
addition, given the lapse of time since we published the interim rule,
we propose updating the interim rule's tables as of December 2013.
Therefore, we are issuing an SNPRM, rather than proceeding directly
from the 2013 interim rule to a final rule, so that, in the interest of
ensuring the accuracy of our tables, we can take another round of
public comments before issuing a final rule.
---------------------------------------------------------------------------

    \2\ ``2012 Liquid Chemical Categorization Updates; Interim
Rule,'' 78 FR 50147 (Aug. 16, 2013). Because the interim rule
contained information updated only through December 2012, it bore
the heading ``2012 Liquid Chemical Categorization Updates.'' This
SNPRM is headed ``2013 Liquid Chemical Categorization Updates''
because it has been updated as of the December 2013 MEPC Circular,
but the SNPRM shares the same docket with the interim rule.
    \3\ See 78 FR 56837 (Sep. 16, 2013; delayed until Jan. 16,
2014); 79 FR 2106 (Jan. 13, 2014; delayed until Jan. 16, 2015); 79
FR 68131 (Nov. 14, 2014; delayed until Jan. 16, 2017).
---------------------------------------------------------------------------

    Purpose of tables. Coast Guard regulations in 46 CFR subchapter D
(tank vessels, parts 30 through 39) and subchapter O (certain bulk
dangerous cargoes, parts 150 through 155) contain requirements for
ensuring the safe maritime carriage (transportation) of certain bulk
liquid cargoes. Tables in subchapters D and O list the cargoes that
have been approved for maritime carriage. They also categorize each
cargo's pollution-hazard risk and safe carriage requirements in
accordance with the Coast Guard and International Maritime Organization
(IMO) assessment and review processes described in the following
paragraphs. This information is of value to vessel owners and operators
and to shippers of the cargoes involved.
    Initial cargo assessment. If a vessel owner or operator plans to
ship a newly-developed chemical substance internationally, as a bulk
liquid cargo, the new cargo's chemical properties need to be assessed
to ensure safe carriage.\4\ Our tables contain cargo categorization
information that derives from this initial assessment.
---------------------------------------------------------------------------

    \4\ For Coast Guard approval to ship a cargo not previously
approved for carriage, see 46 CFR 153.900.
---------------------------------------------------------------------------

    Agencies responsible for administering international maritime
treaties (for the U.S., this is the Coast Guard) must agree on the new
cargo's assessment before the cargo can be approved for transportation.
This is done by a ``tripartite agreement'' entered into by the
administrations of the exporting country, the importing country, and
the country in which the ship that will carry the cargo is registered.
The tripartite agreement categorizes the cargo's pollution-hazard risk
and flammability/combustibility in accordance with the International
Code for the Construction and Equipment of Ships Carrying Dangerous
Chemicals in Bulk (IBC Code).\5\ A copy of the tripartite agreement is
forwarded to the IMO's Marine Environment Protection Committee (MEPC)
and to the administration of every country that is signatory to the IBC
Code.
---------------------------------------------------------------------------

    \5\ The IBC Code contains international standards for the safe
maritime bulk transportation of dangerous and noxious liquid
chemicals in accordance with MARPOL and the International Convention
for the Safety of Life at Sea (SOLAS).
---------------------------------------------------------------------------

    The Coast Guard is unique among IBC Code-signatory administrations
because, in addition to the categorizations contained in the tripartite
agreement, it also assigns each cargo to a ``compatibility group.''
This grouping guides IBC signatories and shippers in determining which
cargoes, based on chemical analyses and test data submitted by
manufacturers, would be chemically incompatible with other cargoes and
therefore cannot safely be shipped with those other cargoes in adjacent
tanks, without special precautions.\6\ Our tables also reflect these
compatibility groupings.
---------------------------------------------------------------------------

    \6\ See 46 CFR 150.120, 150.130, and Figure 1 to Part 150 (a
compatibility matrix for determining how cargoes should be grouped).
---------------------------------------------------------------------------

    IMO assessment. Upon receipt of a tripartite agreement, the MEPC
conducts its own multi-year review and assessment of the information
contained in the tripartite agreement, and following that review,
either validates or modifies the agreement's information. Our tables
also reflect any modifications resulting from this IMO assessment.
    Each December, the MEPC releases a circular listing each new cargo
for which it has completed its review of the cargo's tripartite
agreement. The circular lists the countries that have approved
international maritime transportation of each new cargo, and provides
information about the cargo's pollution-hazard risk and flammability/
combustibility. Thus, if a tripartite agreement has approved a cargo
for international bulk maritime transportation and the MEPC validates
or modifies that information, eventually it will be listed in the MEPC
circular.
    Periodically, the IBC Code is revised, and cargoes listed in MEPC
annual circulars since the last edition of the IBC Code are
incorporated. The IBC Code was last comprehensively revised in 2007, at
which time the previous pollution categorization scheme (categories A,
B, C, and D, which indicate a cargo's relative pollution-hazard risk)
were replaced by categories X, Y, Z, and OS (for ``other cargoes,''
which at present are considered to pose no risk).\7\ Our tables are
intended to reflect the latest IBC Code revision, but until this
rulemaking, they were not updated to incorporate the changes made by
the 2007 IBC Code revision.
---------------------------------------------------------------------------

    \7\ See MARPOL, Annex II, Chapter 2, Regulation 6. With respect
to the discharge of a cargo into the sea from tank cleaning or
deballasting operations and the resulting hazard posed to marine
resources or human health, the new categories indicate:
     X = Major hazard justifying prohibition of the
discharge;
     Y = Hazard justifying a limitation on the quality and
quantity of the discharge;
     Z = Minor hazard justifying less stringent restrictions
on the quality and quantity of the discharge; and
     OS = No harm that justifies special discharge
requirements
---------------------------------------------------------------------------

    IMO actions reflected in this rulemaking. In March 2012, the IMO
published an Annex to the 2007 IBC Code, listing additional cargoes
with their pollution categorizations.
    Until we published our 2013 interim rule, the tables in subchapter
D and subchapter O had gone unamended for several years, and still
contained the pre-2007 pollution categorizations. The interim rule
updated the following tables as of the December 2012 MEPC circular:
     ``Table 30.25-1'' in subchapter D;
     ``Table I to Part 150'' in subchapter O;
     ``Table II to Part 150'' in subchapter O; and
     ``Table 2 to Part 153'' in subchapter O.
    This supplemental notice of proposed rulemaking (SNPRM) proposes
updating these tables as of the December 2013 circular. All four tables
include cargoes that are listed either in MEPC circulars, or in
tripartite agreements to which the U.S. is a party. (Information from
other tripartite agreements is excluded pending MEPC review.)
    Table contents. Table 30.25-1 lists flammable or combustible
cargoes that, when transported in bulk, must be certificated under
subchapter D regulations.
    The two tables in part 150 contain the Coast Guard chemical
compatibility categorization for each cargo. Table I lists all cargoes
alphabetically and provides a category group for each. Table II lists
cargoes by group.
    Table 2 to Part 153 lists cargoes that, when carried in bulk on
non-oceangoing barges, are not subject to subchapter D or O
regulations, but that must comply with subchapter O if they are carried
on oceangoing ships.\8\
---------------------------------------------------------------------------

    \8\ Table 1 to Part 153, ``Summary of Minimum Requirements [for
safe carriage]'' is not amended by this rulemaking. It lists a
fuller list of minimum safe carriage requirements than those
contained in the tables that this rulemaking amends. Because of
Table 1's greater complexity, it may be the subject of a future
rulemaking, pending study and recommendations from the Coast Guard's
Chemical Transportation Advisory Committee.
---------------------------------------------------------------------------

    Comments on 2013 interim rule and resulting changes. Our interim
rule prompted comments from two individuals and four industry
representatives, one of whom made multiple submissions. The two

individuals commented on the safety of food containing genetically
modified organisms. That is not an issue raised by our rulemaking and
therefore is beyond its scope.
    Three commenters asked why we had not discussed draft table updates
with the Chemical Transportation Advisory Committee (CTAC), a group
that advises the Coast Guard on chemical transportation matters, and
suggested that consultation with CTAC could be helpful, along with more
time for industry to review the interim rule before it took effect.
CTAC operates pursuant to the Federal Advisory Committee Act, which
requires advisory committees to operate under a valid charter.\9\ From
2009 until 2013, the period during which we developed the interim rule,
CTAC lacked such a charter and therefore was not operational. Since its
reestablishment in 2013, we have kept CTAC apprised as to this
rulemaking's status, but at no time has CTAC expressed the desire to
make formal recommendations to the Coast Guard as to the rulemaking's
direction. We are open to future CTAC recommendations, and individual
CTAC members are welcome to comment on this SNPRM, as they are on any
Coast Guard rulemaking. As to additional industry time for review, we
believe the continuing delay in the interim rule's effective date has
provided ample additional review time.
---------------------------------------------------------------------------

    \9\ 5 U.S.C. Appendix 2, sec. 9(c).
---------------------------------------------------------------------------

    Three commenters said that, in Table I to Part 150, we mistakenly
listed several cargoes in compatibility group 4, when in the past they
have been listed in group 34 and not group 4. We agree this was a
mistake and this SNPRM shows the cargoes in group 34.
    One commenter asked if we consider that all cargoes shown in Table
30.25-1 or Table 2 to Part 153 as ``n.o.s.'' (``not otherwise
specified'') should be assigned in Table I to Part 150 in group 0. We
do not. Group 0 is the default assignment for a cargo that we have
either determined cannot be shipped safely with any other cargo, or for
a cargo for which we are unable to make any other assignment because we
lack sufficient chemical analysis and test data on which to make that
assignment. These criteria do not necessarily apply to an ``n.o.s.''
cargo, and therefore we assign many ``n.o.s.'' cargoes to compatibility
groups other than group 0.
    One commenter said that sodium methylate 21-30%, instead of being
listed in compatibility group 20, should be listed in group 0 due to
its highly reactive nature, and that diglycidyl ether of bisphenol A
and F should be listed in compatibility group 18 rather than in group
41. We agree that the interim rule incorrectly listed these cargoes and
this SNPRM shows sodium methylate 21-30% in group 0 and diglycidyl
ether of bisphenol A and F in group 18.
    One commenter addressed the interim rule's amendment to ``Appendix
I to Part 150--Exceptions to the Chart.'' The ``chart'' referred to is
Figure 1 to Part 150, a matrix showing how cargo compatibility can be
determined. Appendix I lists binary combinations of substances that are
treated as exceptions to Figure 1 because they have been tested and
found not to be dangerously reactive. One commenter said that our
revision of Appendix I failed to list between 10 and 15 previously
approved exceptions. We agree and this SNPRM restores those exceptions
to Appendix I.
    One commenter said we should have expanded the interim rule's
discussion of tripartite agreements, and we have done so accordingly in
the ``Background'' section of this SNPRM. In addition to the changes we
have made in response to comments, we are also restoring liquefied
flammable gas listings in subchapter D's Table 30.25-1. We removed
those listings in the interim rule, in anticipation of a policy change
that would have allowed them to fall exclusively under subchapter O.
That policy change has not occurred and we have restored the listings
in this SNPRM.
    It is our intention, for future years, to keep the tables updated
annually.This SNPRM proposes the addition of new entries that would
bring them up to date as of the December 2013 MEPC Circular.
    We specifically request public comment on whether or not this
SNPRM's information is correct, and in particular whether or not we
have correctly and fully responded to comments on the interim rule and
brought our information up to date as of December 2013.

IV. Regulatory Analyses

A. Regulatory Planning and Review

    Executive Orders (E.O.s) 12866 (``Regulatory Planning and Review'')
and 13563 (``Improving Regulation and Regulatory Review'') direct
agencies to assess the costs and benefits of available regulatory
alternatives and, if regulation is necessary, to select regulatory
approaches that maximize net benefits (including potential economic,
environmental, public health and safety effects, distributive impacts,
and equity). Executive Order 13563 emphasizes the importance of
quantifying both costs and benefits, of reducing costs, of harmonizing
rules, and of promoting flexibility. This proposed rule has not been
designated a ``significant regulatory action'' under section 3(f) of
E.O. 12866. Accordingly, the proposed rule has not been reviewed by the
Office of Management and Budget. A draft regulatory assessment is
included herein.
Affected Population
    This proposed rule updates tables that list the names, pollution
risk categorizations, and safe carriage requirements of liquid chemical
cargoes that have already been categorized and approved for maritime
transportation in bulk, either permanently or on a provisional basis.
This proposed rule makes no new decisions about whether any specific
chemical cargo should be approved for bulk maritime transportation,
about how any specific cargo should be categorized, or about carriage
requirements that should apply to any specific cargo. It simply
provides updated information about cargoes that are currently approved
for maritime transportation in bulk, and the cargo's pollution
categorization and minimum transportation safety requirements. This
proposed rule indirectly applies to the carriage of the subject cargoes
from the following tank vessel populations as described in 46 CFR
30.01-5, 150.115 (with exceptions described in 46 U.S.C. 3702), 153.1,
and 154.5 as described therein. All U.S. tank vessels are included.
Foreign tank vessels are, in general, exempt from this regulation when
on innocent passage through U.S. waters, except for liquefied gas
cargo/cargo residue or vapor carriers. Also included are self-propelled
bulk cargo carrying oceangoing/non-oceangoing U.S.-flag and oceangoing
foreign-flag vessels when in U.S. waters.
Costs
    This proposed rule updates tables that list the names, pollution
risk categorizations, and safe carriage requirements of liquid chemical
cargoes that have already been categorized and approved by the United
States and the IMO for maritime transportation in bulk, either
permanently or on a provisional basis. Since this proposed rule simply
updates tables and a table preface to reflect decisions already made
under international law about which liquid chemical cargoes are
approved for bulk maritime transportation, and about how those cargoes
should be categorized with respect to their pollution potential, it
does not change established shipping requirements and there are no
private sector costs expected from this supplemental notice of proposed
rule.

The only party that will incur any cost will be the Coast Guard. This
cost is for 40 hours total of updating work on approximately 50
chemicals per year, for an approximate annual cost of $3,200. The cost
is based on 40 hours times the loaded hourly cost to the Coast Guard
(wages and employee benefits) of employing a GS-13 or equivalent ($80).
The source for this is Commandant Instruction 7310.1P (http://www.uscg.mil/directives/ci/7000-7999/CI_7310_1P.pdf).
    In addition, the proposals would correct errors and omissions in
the interim rule and bring the tables current through December 2013.
This proposed rule incorporates Coast Guard compatibility
categorizations and chemical cargoes and categorizations listed by the
IMO through its December 2013 MEPC Circular.
Benefits
    The primary benefit of this proposed rule is to conform regulatory
language to practices currently allowed by the Coast Guard through
either individual letters of approval or the IBC Code as discussed
above, which we expect will result in the benefit of improved service
to the public through improved clarity and transparency.

B. Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612) (RFA), we
have considered whether this proposed rule would have a significant
economic impact on a substantial number of small entities. The term
``small entities'' comprises small businesses, not-for-profit
organizations that are independently owned and operated and are not
dominant in their fields, and governmental jurisdictions with
populations of less than 50,000. Since this proposed rule does not
impose any additional direct costs, it does not impose any additional
direct costs on small entities as defined by the RFA. Therefore, the
Coast Guard certifies that under 5 U.S.C. 605(b), the proposed rule
will not have a significant economic impact on a substantial number of
small entities.
    If you think that your business, organization, or governmental
jurisdiction qualifies as a small entity and that this rule would have
a significant economic impact on it, please submit a comment to the
Docket Management Facility at the address under ADDRESSES. In your
comment, explain why you think it qualifies and how and to what degree
this rule would economically affect it.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small
entities in understanding this rule so that they can better evaluate
its effects on them and participate in the rulemaking. If this proposed
rule would affect your small business, organization, or governmental
jurisdiction and you have questions concerning its provisions or
options for compliance, please consult Mr. Patrick Keffler at
<EMAIL_ADDRESS>The Coast Guard will not retaliate against
small entities that question or complain about this proposed rule or
any policy or action of the Coast Guard.

D. Collection of Information

    This proposed rule would call for no new collection of information
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). This
proposed rule simply updates and revises tables that list cargoes that
have been approved and categorized for bulk maritime transportation,
which does not involve information collection.

E. Federalism

    A rule has implications for federalism under E.O. 13132
(``Federalism'') if it has a substantial direct effect on the States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government. We have analyzed this proposed rule under that
E.O. and have determined that it is consistent with the fundamental
federalism principles and preemption requirements described in the E.O.
Our analysis follows.
    It is well-settled that States may not regulate in categories
reserved for regulation by the Coast Guard, including categories for
inspected vessels. It is also well-settled, that all of the categories
covered in 46 U.S.C. 3306, 3703, 7101, and 8101 (design, construction,
alteration, repair, maintenance, operation, equipping, personnel
qualification, and manning of vessels), as well as the reporting of
casualties and any other category in which Congress intended the Coast
Guard to be the sole source of a vessel's obligations, are within
fields foreclosed from regulation by the States (See the decision of
the Supreme Court in the consolidated cases of United States v. Locke
and Intertanko v. Locke, 529 U.S. 89 (2000). This proposed rule amends
existing regulations for inspected vessels carrying certain bulk
dangerous cargoes, which, under the principles discussed in Locke, fall
within the categories enumerated in 46 U.S.C. 3306 and 3703, which are
themselves within fields in which the states are foreclosed from
regulating. Therefore, because the States may not regulate within these
categories, this rule is consistent with the fundamental federalism
principles and preemption requirements described in E.O. 13132.
    While it is well settled that States may not regulate in categories
in which Congress intended the Coast Guard to be the sole source of a
vessel's obligations, the Coast Guard recognizes the key role that
State and local governments may have in making regulatory
determinations. Additionally, for rules with federalism implications
and preemptive effect, Executive Order 13132 specifically directs
agencies to consult with State and local governments during the
rulemaking process. If you believe this proposed rule has implications
for federalism under Executive Order 13132, please contact the person
listed in the FOR FURTHER INFORMATION CONTACT section of this preamble.

F. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538)
requires Federal agencies to assess the effects of their discretionary
regulatory actions. In particular, the Act addresses actions that may
result in the expenditure by a State, local, or tribal government, in
the aggregate, or by the private sector of $100,000,000 (adjusted for
inflation) or more in any one year. Though this proposed rule will not
result in such an expenditure, we do discuss the effects of this rule
elsewhere in this preamble.

G. Taking of Private Property

    This proposed rule will not cause a taking of private property or
otherwise have taking implications under E.O. 12630 (``Governmental
Actions and Interference with Constitutionally Protected Property
Rights'').

H. Civil Justice Reform

    This proposed rule meets applicable standards in sections 3(a) and
3(b)(2) of E.O. 12988 (``Civil Justice Reform'') to minimize
litigation, eliminate ambiguity, and reduce burden.

I. Protection of Children

    We have analyzed this proposed rule under E.O. 13045 (``Protection
of Children from Environmental Health Risks and Safety Risks''). This
proposed rule is not an economically significant rule and does not
create an environmental risk to health or risk to

safety that may disproportionately affect children.

J. Indian Tribal Governments

    This proposed rule does not have tribal implications under E.O.
13175 (``Consultation and Coordination with Indian Tribal
Governments'') because it does not have a substantial direct effect on
one or more Indian tribes, on the relationship between the Federal
Government and Indian tribes, or on the distribution of power and
responsibilities between the Federal Government and Indian tribes.

K. Energy Effects

    We have analyzed this proposed rule under E.O. 13211 (``Actions
Concerning Regulations That Significantly Affect Energy Supply,
Distribution, or Use''). We have determined that it is not a
``significant energy action'' under that E.O. because it is not a
``significant regulatory action'' under E.O. 12866 and is not likely to
have a significant adverse effect on the supply, distribution, or use
of energy. The Administrator of the Office of Information and
Regulatory Affairs has not designated it as a significant energy
action. Therefore, it does not require a Statement of Energy Effects
under E.O. 13211.

L. Technical Standards

    The National Technology Transfer and Advancement Act (15 U.S.C. 272
note) directs agencies to use voluntary consensus standards in their
regulatory activities unless the agency provides Congress, through the
OMB, with an explanation of why using these standards would be
inconsistent with applicable law or otherwise impractical. Voluntary
consensus standards are technical standards (e.g., specifications of
materials, performance, design, or operation; test methods; sampling
procedures; and related management systems practices) that are
developed or adopted by voluntary consensus standards bodies. This
proposed rule does not use technical standards. Therefore, we did not
consider the use of voluntary consensus standards.

M. Environment

    We have analyzed this proposed rule under Department of Homeland
Security Management Directive 023-01 and Commandant Instruction
M16475.lD, which guide the Coast Guard in complying with the National
Environmental Policy Act of 1969 (NEPA)(42 U.S.C. 4321-4370f), and have
made a preliminary determination that this action is one of a category
of actions that do not individually or cumulatively have a significant
effect on the human environment. A preliminary environmental analysis
checklist supporting this determination is available in the docket
where indicated under the ``Public Participation and Comments'' section
of this preamble. This proposed rule involves administrative updates of
existing chemical transport regulations and updates provisions relating
to the chemical properties of liquid chemical cargoes approved for
maritime transportation in bulk. The update incorporates changes in how
approved cargoes are categorized by their chemical properties. This
proposed rule promotes the Coast Guard's maritime safety and
stewardship missions. It is therefore included in the Coast Guard's
Commandant Instruction (COMDTINST) M16475.1D, Figure 2-1, which
includes categorical exclusions (CEs) under categories (34)(a),
``regulations which are editorial or procedural, such as those updating
addresses or establishing application procedures,'' and 34 (d),
``regulations concerning manning, documentation, admeasurement,
inspection, and equipping of vessels,'' as well as in the ``Appendix to
National Environmental Policy Act: Coast Guard Procedures for
Categorical Exclusions, Notice of Final Agency Policy'' (see 67 FR
48243, July 23, 2002) under paragraph 6 (a), ``regulations concerning
vessel operation safety standards . . . equipment approval, and/or
equipment carriage requirements . . . and visual distress signals.'' We
seek any comments or information that may lead to the discovery of a
significant environmental impact from this proposed rule.

August 16, 2013 (78 FR 50148), effective January 16, 2017, as delayed
at 79 FR 68132, November 14, 2014, to read as follows:

Sec.  30.25-1  Cargoes carried in vessels certificated under the rules
of this subchapter.

    (a) Table 30.25-1 lists flammable or combustible cargoes that, when
transported in bulk, must be in vessels certificated under this
subchapter D.
    (b) A mixture or blend of two or more cargoes appearing in Table
30.25-1 may be transported under this subchapter D.
    (c) A mixture or blend of one or more cargoes appearing in Table
30.25-1 and one or more cargoes appearing in Table 2, 46 CFR part 153,
may be carried under this subchapter D if the mixture is flammable or
combustible.
    (d) Any mixture containing one or more cargoes categorized by the
International Maritime Organization (IMO) and listed in Table 30.25-1
as a category X, Y, or Z noxious liquid substance (NLS) may be carried
in bulk--
    (1) Under this subchapter D if the vessel is not regulated under 46
CFR part 153; or
    (2) Under part 153 if the vessel is regulated under that part; or
alternatively under 33 CFR part 151 if the cargo is listed in 33 CFR
151.49; or
    (3) Under 33 CFR part 151 if the cargo is listed in 33 CFR 151.47.
