2022 Liquid Chemical Categorization Updates

AGENCY: Coast Guard, DHS.

ACTION: Final rule.

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

SUMMARY: The Coast Guard is issuing this final rule to align liquid
chemical categorization tables in its tank vessels and bulk dangerous
cargo regulations with the 2020 Edition of the International Code for
the Construction and Equipment of Ships Carrying Dangerous Chemicals in
Bulk. The updated tables provide a list of the liquid hazardous
materials, liquefied gases, and compressed gases approved for
international and domestic maritime transportation and indicate how
each substance is categorized by its pollution potential, safe carriage
requirements, chemical flammability, combustibility, and compatibility
with other substances. This rule imposes no additional costs to
chemical shippers or vessel owners.

DATES: This final rule is effective December 21, 2023.

Sec.  Section
U.S.C. United States Code

II. Basis and Purpose

    The legal basis of this rulemaking is title 46 of the United States
Code (U.S.C.), Section 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
(Administration and enforcement, regulations to implement the
International Convention for the Prevention of Pollution from Ships
(MARPOL) Protocol of 1978 relating to the International Convention for
the Prevention of Pollution from Ships, 1973), 46 U.S.C. 2103
(Superintendence of the merchant marine, general merchant marine
regulatory authority), and 46 U.S.C. 3306 (Regulations, 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 the Department of Homeland Security (DHS) Delegation 00170.1,
Revision No. 01.3, paragraphs (II)(77) and (92)(a) and (b).
    The purpose of this rulemaking is to provide updates to regulatory
tables that list liquid hazardous materials, liquefied gases, and
compressed gases that have been approved for maritime transportation in
bulk, and to indicate how each cargo is categorized by its pollution
risk and safe carriage requirements.

III. Background

    The Coast Guard is tasked by Congress with promulgating regulations
to improve the shipping practices in the United States. Since 1983, the
Coast Guard has published tables with chemicals that are safe to ship
together, and others that are incompatible for shipping, in order to
improve their shipping safety.
    Each December, the International Maritime Organization's (IMO)
Marine Environment Protection Committee (MEPC) releases an annual
circular that lists cargoes which have undergone a multi-year review to
determine safe carriage requirements. A cargo is listed in the circular
if a tripartite agreement approved it for international bulk maritime
transportation and the MEPC validated the approval. The International
Code for the Construction and Equipment of Ships Carrying Dangerous
Chemicals in Bulk (IBC Code) is periodically revised by parties to the
IBC Code to include the updated cargoes listed in the MEPC annual
circulars.
    The Coast Guard, as the administrator of regulations that control
liquid chemical shipping practices, has endeavored to update these
regulations to keep the Code of Federal Regulations (CFR) aligned with
international standards. This rulemaking is one in a planned series of
rulemakings that will periodically update the Code of Federal
Regulations (CFR) to align with latest updates of the IBC Code (2020).
The last time the Coast Guard updated these regulations was in a final
rule published April 17, 2020 entitled ``2013 Liquid Chemical
Categorization Updates'' (85 FR 21660).\1\ In addition, the Coast Guard
corrected minor typographical errors in a correcting amendments
document published May 8, 2020 and effective May 18, 2020 and entitled
``2013 Liquid Chemical Categorization Updates; Correction'' (85 FR
27308).\2\ The Coast Guard corrected additional minor errors in a
correcting amendments document published and effective on August 5,
2021 and entitled ``2013 Liquid

Chemical Categorization Updates'' (86 FR 42738).\3\

IV. Discussion of Comments

    On September 22, 2022, the Coast Guard published a notice of
proposed rulemaking (NPRM) titled ``2022 Liquid Chemical Categorization
Updates'' (87 FR 57984) requesting comments on the proposed changes
implemented by this final rule.\4\ The comment period for the NPRM
ended on December 21, 2022. The Coast Guard received no comments on the
proposed rule.

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

V. Discussion of the Rule

    Coast Guard regulations in 46 CFR chapter I subchapters D (Tank
vessels, parts 30 through 40) and 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. The tables also categorize each cargo's
pollution-hazard risk and safe carriage requirements. The categories
are developed during the Coast Guard and MEPC's assessment and review
processes, which are described in the following paragraphs. This rule
incorporates information from MEPC Resolution number 2, Circular 25,
dated December 1, 2019 (MEPC.2/Circ.25) \5\ that vessel owners and
operators, and shippers use to transport such cargoes safely and so
brings 46 CFR chapter I subchapters D and O into closer conformity with
the IBC Code (2020).
---------------------------------------------------------------------------

    \5\ This document is available in the docket and accessible
online at https://docs.imo.org/Shared/Download.aspx?did=119893.
---------------------------------------------------------------------------

    The agencies administering international treaties must agree on the
new cargo's assessment before the cargo can be approved for
transportation. This is done by a tripartite agreement between 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,
flammability, and combustibility in accordance with the IBC Code. A
copy of the tripartite agreement is forwarded to the MEPC and to the
administration of every country that is signatory to the IBC Code.
    The Coast Guard is unique among IBC Code-signatory administrations
because, in addition to categorizing the cargo in the tripartite
agreement, the Coast Guard also assigns each cargo to a compatibility
group. The compatibility grouping guides IBC signatories and shippers
in determining which cargoes cannot safely be shipped with other
cargoes in adjacent tanks, without special precautions. The
compatibility grouping is informed by chemical analyses and test data
submitted by manufacturers. 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 assessment. Each December, the MEPC releases a
circular listing each new cargo for which it has completed its review.
The circular lists the countries that have approved each new cargo for
international maritime transportation and provides information about
each cargo's pollution-hazard risk, flammability and combustibility.
Periodically, the IBC Code is revised to update the cargoes listed in
the MEPC's annual circulars.
    This rule brings the following tables in 46 CFR chapter I into
closer conformity with the IBC Code (2020) by incorporating information
from MEPC.2/Circ.25:
     Table 30.25-1, List of Flammable and Combustible Bulk
Liquid Cargoes, in subchapter D;
     Table 1 to Part 150, Alphabetical List of Cargoes, in
subchapter O;
     Table 2 to Part 150, Grouping of Cargoes, in subchapter O;
and
     Appendix I to Part 150, Exceptions to the Chart, in
subchapter O.
    Table 30.25-1 lists flammable or combustible cargoes that, when
transported in bulk, must be in vessels certificated under subchapter D
regulations. We are updating Table 30.25-1 to add flammable or
combustible chemicals that are approved for shipping by the IBC Code
(2020) and appear in the MEPC.2/Circ.25. The circular is available
online at http://ocn.cl/wp-content/uploads/2021/03/IMO-MEPC-2-CIRC-25-2019.pdf.
    Table 1 to Part 150 is a comprehensive table that includes all
cargoes subject to the regulations in subchapter D. Table 1 lists these
cargoes alphabetically and lists the chemical compatibility group
number assigned to each cargo. We are updating Table 1 to include
cargoes that have been approved for shipping by the IBC Code (2020) and
MEPC.2/Circ.25.
    Table 2 to Part 150 contains the proper shipping names of all the
cargoes listed in Table 1, sorted by chemical compatibility group
numbers instead of listed alphabetically. We align Table 2 with Table 1
to Part 150 and so update it to include cargoes that have been approved
for shipping by the IBC Code (2020) and MEPC.2/Circ.25.
    Appendix I to Part 150 contains cargoes listed in Tables 1 and 2 to
Part 150 that have positive chemical compatibility exceptions. To
illustrate, consider the following: cargoes in group X and cargoes in
group Y are generally incompatible for co-shipping. However, there is
one cargo in group X and one cargo in group Y that, for whatever
reason, can be shipped together safely. This is an example of a
positive chemical compatibility exception, and it would be listed in
Appendix I so that stakeholders can maximize the efficiency of their
shipping practices. We are updating Appendix I to include cargoes from
the updated tables 1 and 2 that have such positive exceptions.
    To further illustrate how the chemical categorization tables work
together, Section (b) of Appendix I to Part 150 contains cargoes listed
in tables 1 and 2 that have negative chemical compatibility exceptions.
Even if cargoes from hypothetical group X and group Y are generally
compatible for co-shipping, there may be a particular chemical in group
X that, when stored with a particular chemical from group Y, can react
dangerously. This is an example of a negative chemical compatibility
exception and would be listed in Appendix I(b) so that stakeholders can
be sure to ship such cargoes safely.
    We are including one addition to section (b) of Appendix I to Part
150 that was not included in the proposed rule. On March 2, 2023, the
Coast Guard received a report from industry stakeholders detailing
testing procedures that demonstrated the incompatibility of Glycol
ethers (Group 40) and Acrylonitrile (Group 15). According to the
report, which is available in the docket, the chemical reaction that
resulted from the reactivity test released gas and increased
temperatures. We have decided to include this negative chemical
compatibility exception in this final rule in the interest of public
safety.
    In addition to the introduction of new chemicals into these tables,
the Coast Guard is adding a new column to Table 1 to Part 150 that
contains a CAS Registry Number (RN). CAS, a division of the non-profit
organization American Chemical Society, designed the CAS Registry to
prevent the frustration, delays, and safety concerns that can come with
a convoluted system of

identifying chemicals. A CAS RN is a unique and unambiguous identifier
for a specific substance that allows clear communication and links
together all available data and research about that substance.
Government agencies rely on CAS RNs for substance identification in
regulatory applications because they are unique, easily validated, and
internationally recognized. The addition of the CAS RNs makes it easier
to use the information and leads to safer shipping practices.
    The Coast Guard considered proposing the removal of Chemical
Hazards Response Information System (CHRIS) codes from the tables.
While the Coast Guard decided not to propose such a removal in the
proposed rule, we solicited comments from the public on the utility of
CHRIS codes. Having received no comments, the Coast Guard will not
remove the CHRIS codes in this final rule. However, the next iteration
of updates to these tables will most likely propose the removal of the
CHRIS codes, which are no longer used in practice.
    The rule also revises the authority citation to 46 CFR part 150 so
that it no longer cites 44 U.S.C. 3507 in citing DHS Delegation No.
00170.1. This was done because DHS Delegation No. 00170.1 does not
address 44 U.S.C. 3507 and that statute dictates the manner in which
the Coast Guard may seek approval to collect information, rather than
delegating authority to edit the CFR. The authority citation is further
revised to reflect another revision to the citation of DHS Delegation
No. 00170.1.
    In this final rule, we also add clarifying language to the chemical
entries, make conforming edits across the tables, and correct
typographical and punctuation errors. We have also edited the Notes and
formatting in the tables to make them easier to understand.

VI. Regulatory Analyses

    We developed this rule after considering numerous statutes and
Executive orders related to rulemaking. Below we summarize our analyses
based on these statutes or Executive orders.

A. Regulatory Planning and Review

    Executive Orders 12866 (Regulatory Planning and Review), as amended
by Executive Order 14094 (Modernizing Regulatory 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.
    Executive Order 13610 (Identifying and Reducing Regulatory Burdens)
promotes the goals of Executive Order 13563. Executive Order 13610 aims
to modernize the regulatory systems and to reduce unjustified
regulatory burdens and costs on the public.
    The Office of Management and Budget (OMB) has not designated this
rule a significant regulatory action under section 3(f) of Executive
Order 12866, as amended by Executive Order 14094. Accordingly, OMB has
not reviewed this regulatory action. A regulatory analysis (RA)
follows.
    The Coast Guard received no comments from the public on the
proposed rule. Since there was no feedback from public commenters that
would require changes to the regulatory analysis for this final rule,
we adopt the regulatory analysis that we presented in the proposed
rule.
Summary of Impacts of This Rule
    In this rule, the Coast Guard incorporates information from MEPC.2/
Circ.25 into the tables of subchapters D and O to conform the tables
with the IBC Code (2020). In subchapter D, we revise table 30.25-1; in
subchapter O, we revise tables 1 and 2 and Appendix I to part 150. A
summary of the impacts from the rule follows.

                                     I to Part 150 in subchapter O to
                                     incorporate information from MEPC.2/
                                     Circ.25.

                                     incorporating information from
                                     MEPC.2/Circ.25.
                                    Clarifies regulatory requirements
                                     and makes the updated chemical
                                     information easier to use.
------------------------------------------------------------------------

Affected Population
    This rule updates the Liquid Chemical Categorization (LCC) tables
that list the names, pollution risk categorization, safe carriage
requirements, chemical flammability, combustibility, and chemical
compatibility of each liquid hazardous material, liquefied gas, and
compressed gas that has been categorized and approved for maritime
transportation in bulk by the IMO and the Coast Guard. In this rule,
the Coast Guard is making no additional changes about whether any
specific liquid bulk dangerous cargo is approved for maritime
transportation, about how any specific cargo is categorized, or about
carriage requirements that apply to any specific cargo. The rule
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. The rule
also adds a column to Table 1 of part 150 containing the applicable CAS
RNs. This rule applies to the carriage of the cargoes by the vessel
population described in 46 CFR 30.01-5, 150.110 (with exceptions
outlined in 46 U.S.C. 3702), 153.1, and 154.5. All U.S.- and foreign-
flagged tank vessels are included, unless exempted by 46 CFR 30.01-5 or
46 CFR 153.1. This rule also applies to U.S.- and foreign-flagged self-
propelled bulk cargo-carrying vessels when in U.S. waters, see 46 CFR
153.1. Foreign tank vessels are exempt from this regulation when on
innocent passage through U.S. waters, see 33 CFR 157.01.
Costs
    This rule updates the tables to reflect changes already made under
MEPC approved tripartite agreements regarding which liquid chemical
substances are approved for bulk maritime transportation, and how those
substances are categorized with respect to their pollution risk. The
Coast Guard already applies these standards when assessing ad hoc
domestic carriage requests for liquid chemicals. Vessel owners and
chemical shippers will have to comply with these standards to receive
Coast Guard approval for carriage. Industry is aware of this

procedure, and we believe that chemical shippers already comply with
these standards. Therefore, the Coast Guard does not expect that this
rule will change established shipping requirements or current practices
among chemical shippers. No additional labor or equipment will be
required because of this rule. As a result, we expect that there will
be no incremental private sector costs to chemical shippers or vessel
owners. Further, we do not anticipate that the rule will impose any
additional costs on the Coast Guard. This rule incorporates the Coast
Guard's compatibility categorizations, as well as chemical cargoes and
categorizations listed in IMO's IBC Code (2020) and MEPC.2/Circ.25.
Benefits
    The rule provides qualitative benefits by updating the LCC tables,
thereby aligning the domestic shipping requirements for liquid bulk
dangerous cargoes with current international standards. The Coast Guard
expects this rule to serve the public through greater clarity regarding
the regulatory requirements in the LCC tables and through easier use of
chemical safety information. This rule codifies existing industry
practices which will add clarity about regulatory requirements in the
LCC tables.

B. Small Entities

    Under the Regulatory Flexibility Act, 5 U.S.C. 601-612, we have
considered whether this rule has 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.
    There are no small vessel owners or chemical shippers engaged in
the transport of the LCC chemicals. In addition, the rule does not
impose economic costs on the regulated public. The Coast Guard does not
expect that small entities will incur any incremental costs; therefore,
the Coast Guard finds that there is no significant impact on small
entities nor are a substantial number of small entities incurring
impacts. Therefore, the Coast Guard certifies under 5 U.S.C. 605(b)
that this rule will not have a significant economic impact on a
substantial number of small entities.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement
Fairness Act of 1996, Public Law 104-121, we offer to assist small
entities in understanding this rule so that they can better evaluate
its effects on them and participate in the rulemaking. The Coast Guard
will not retaliate against small entities that question or complain
about this rule or any policy or action of the Coast Guard.
    Small businesses may send comments on the actions of Federal
employees who enforce, or otherwise determine compliance with, Federal
regulations to the Small Business and Agriculture Regulatory
Enforcement Ombudsman and the Regional Small Business Regulatory
Fairness Boards. The Ombudsman evaluates these actions annually and
rates each agency's responsiveness to small business. If you wish to
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR
(1-888-734-3247).

D. Collection of Information

    This rule calls for no new or revised collection of information
under the Paperwork Reduction Act of 1995, 44 U.S.C. 3501-3520. This
rule simply updates tables that list liquid bulk dangerous 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 Executive Order 13132
(Federalism) if it has a substantial direct effect on 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 rule under Executive Order 13132 and
have determined that it is consistent with the fundamental federalism
principles and preemption requirements described in Executive Order
13132. Our analysis follows.
    It is well settled that States may not regulate in categories
reserved for regulation by the Coast Guard. 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 the field foreclosed from regulation by the
States. This rule would amend existing regulations for inspected tank
vessels carrying certain bulk dangerous cargoes. These cargoes fall
within the categories in 46 U.S.C. 3703 and 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 Executive Order 13132.

F. Unfunded Mandates

    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. Although this rule will not result
in such expenditure, we do discuss the effects of this rule elsewhere
in this preamble.

G. Taking of Private Property

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

H. Civil Justice Reform

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

I. Protection of Children

    We have analyzed this rule under Executive Order 13045 (Protection
of Children from Environmental Health Risks and Safety Risks). This
rule is not an economically significant rule and will not create an
environmental risk to health or risk to safety that might
disproportionately affect children.

J. Indian Tribal Governments

    This rule does not have tribal implications under Executive Order
13175 (Consultation and Coordination with Indian Tribal Governments),
because it will 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 rule under Executive Order 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 order because

it is not a ``significant regulatory action'' under Executive Order
12866 and is not likely to have a significant adverse effect on the
supply, distribution, or use of energy.

L. Technical Standards

    The National Technology Transfer and Advancement Act, codified as a
note to 15 U.S.C. 272, directs agencies to use voluntary consensus
standards in their regulatory activities unless the agency provides
Congress, through 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 rule does not use technical standards. It is based on
international standards that were developed using consensus standards
development processes. Therefore, we did not consider the use of
voluntary consensus standards.

M. Environment

    We have analyzed this rule under Department of Homeland Security
Management Directive 023-01, Rev. 1, associated implementing
instructions, and Environmental Planning COMDTINST 5090.1 (series),
which guide the Coast Guard in complying with the National
Environmental Policy Act of 1969 (42 U.S.C. 4321-4370f), and have made
a 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 Record of Environmental Consideration supporting
this determination is available in the docket. For instructions on
locating the docket, see the ADDRESSES section of this preamble.
    This rule meets the criteria for categorical exclusions L52 and L54
of Appendix A, Table 1 of DHS Instruction Manual 023-01-001-01,
Rev.1.\6\ Paragraph L52 pertains to regulations concerning vessel
operation safety standards, equipment approval, and or equipment
carriage requirements; paragraph L54 pertains to promulgation of
regulations that are editorial or procedural. This rule updates the LCC
tables by incorporating information from MEPC.2/Circ.25 to more closely
conform the tables with the IBC Code (2020). These tables provide a
list of liquid hazardous material, liquefied gases, and compressed
gases that are approved for international and domestic maritime
transportation and indicate how each substance is categorized by its
pollution potential, safe carriage requirements, chemical flammability,
combustibility, and compatibility with other substances. All these
changes are consistent with the Coast Guard's maritime safety and
stewardship missions.

Notes:
``#'' = The noxious liquid substance status is undetermined--see 46 CFR
  153.900(c) for shipping on an oceangoing vessel.
``[dagger]'' = Marine occupational safety and health regulations for
  benzene, 46 CFR part 197, subpart C, may apply to this cargo.
``[ ]'' = Provisional categorization to which the United States is
  party.
``@'' = The noxious liquid substance category has been assigned by the
  Coast Guard, in the absence of one assigned by the IMO. The category
  is based on a GESAMP Hazard Profile or, by analogy, to a closely
  related product having a noxious liquid substance assigned.
Bolded entries were added from the March 2012 Annex to the 2007 edition
  of the IBC Code (MEPC 63/23/Add.1), the December 2012 IMO Marine
  Environmental Protection Committee Circular (MEPC.2/Circ.18), or the
  December 2013 IMO Marine Environmental Protection Committee Circular
  (MEPC.2/Circ.19).
``Cat'' = Pollution category.
``F'' = Flammable (flash point less than or equal to 60 [deg]C (140
  [deg]F).
``I'' = An ``oil'' under MARPOL Annex I.
Italicized words are not part of the cargo name, but may be used in
  addition to the cargo name.
``LFG'' = Liquid flammable gas.
``n.o.s.'' = Not otherwise specified.
``OS'' = An ``other substance'' considered at present to pose no harm to
  marine resources, human health, amenities, or other legitimate uses of
  the sea when discharged into the sea from tank cleaning or
  deballasting operations.
``see'' = A redirection to the preferred, alternative cargo name--for
  example, in ``Diethyl ether, see Ethyl ether,'' the pollution category
  for ``diethyl ether'' will be found under the preferred, alternative
  cargo name ``ethyl ether.''
``ST'' = Ship type, as defined in Chapter 2 of the IBC Code (2020).
``X,'' ``Y,'' and ``Z'' = Noxious liquid substance categories under
  MARPOL Annex II.
