Upgrades to Bulk Hazardous Materials Tables
AGENCY: Coast Guard, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Coast Guard is amending its regulations on carriage of
bulk hazardous materials. These amendments assign additional carriage
requirements, a higher Pollution Category, or both to certain
commodities already listed in the tables. These amendments are
necessary to align the minimum requirements in the table with those
approved by the International Maritime Organization (IMO) for inclusion
in its Chemical Codes applicable to tankships. Additionally, the Coast
Guard is making various revisions to correct past errors.
EFFECTIVE DATES: September 30, 1994.
ADDRESSES: Unless otherwise indicated, documents referenced in this
preamble are available for inspection or copying at the office of the
Executive Secretary, Marine Safety Council (G-LRA/3406), U.S. Coast
Guard Headquarters, 2100 Second Street SW., room 3406, Washington, DC

The principal persons involved in drafting this document are Mr.
Curtis G. Payne, Project Manager, and Ms. Helen G. Boutrous, Project
Counsel, Office of Chief Counsel.
Related Rulemakings
On April 11, 1994, the Coast Guard published a final rule (FR)
entitled Bulk Hazardous Materials in the Federal Register (59 FR 16999)
updating its chemical tables to reflect the International Maritime
Organization's (IMO's) final and provisional determinations, with the
exception of ``upgrades'' to entries currently in the IMO Chemical
Code.
On October 17, 1991, the Coast Guard published a final rule
entitled ``Benzene'' in the Federal Register (56 FR 52122) which became
effective January 15, 1992. On December 13, 1991, the Coast Guard
published a correction to that final rule entitled ``Benzene;
Correction'' in the Federal Register (56 FR 65005) which became
effective January 15, 1992.
Elsewhere in this edition of the Federal Register, the Coast Guard
is publishing a final rule concerning upgrades to the noxious liquid
substances lists in 33 CFR 151.47 and 151.49 (CGD 94-901). Also in this
edition of the Federal Register, a notice and request for comments (CGD
94-902) is published concerning cargo entries the Coast Guard has
reason to believe are obsolete.
Background and Purpose
This rulemaking updates various Coast Guard hazardous materials
tables in 46 CFR parts 30, 150, 151, and 153 to include ``upgrades'' to
requirements authorized by Coast Guard regulations or international
law. An ``upgrade'' means that a commodity is assigned additional
carriage requirements, a higher Pollution Category (Pol. Cat.), or
both. The upgrades assigned by this final rule were determined by the
IMO for inclusion in the IMO Chemical Codes (``International Code for
the Construction and Equipment of Ships Carrying Dangerous Chemicals in
Bulk'' (IBC Code), and ``Code for the Construction and Equipment of
Ships Carrying Dangerous Chemicals in Bulk'' (BCH Code)). Adoption of
these upgrades in the Coast Guard regulations is necessary to ensure
consistency with international law. These upgrades were included, for
informational purposes, in an appendix to the Bulk Hazardous Materials
NPRM published on May 20, 1993 (58 FR 29937). At that time, the IMO had
determined the upgrades, but were not scheduled to become effective
until July 1, 1994. The upgrades, with brief explanations where
helpful, are shown in a table in the Discussion of Amendments section
below. The corrections and editorial revisions included in this rule
are also discussed below.
Discussion of Amendments
(a) Benzene and benzene containing cargoes. Concurrent with the
``upgrade'' actions, the IMO has revised the gauging requirement for
benzene and benzene containing cargoes to ``closed''. This revision has
been based upon the known human health hazards posed by the chemical
benzene. Today's rulemaking incorporates this revision in both the
Coast Guard's tankship table of minimum requirements, table 1, part 153
as well as its tank barge table of minimum requirements, table 151.05,
part 151. Compliance with the tankship requirements must be met as of
the effective date of this rule, to coincide, as closely as possible,
with the implementation of the amendment to the IMO Chemical Codes.
However, compliance with the new tank barge requirements of this rule
is not required until August 15, 1994.
(b) Corrections to listed electrical hazard class and group.
As indicated in the Table of Changes below, the currently listed
electrical hazard class and group of various entries in table 151.05 of
46 CFR part 151 are corrected. The entries below were identified by the
Cargo Classification Working Group of the Chemical Transportation
Advisory Committee (CTAC) 151 Subcommittee as having erroneous
electrical hazard class-group listed in the tank barge table. The
revised electrical hazard class and group listings shown below have
been verified using the National Fire Protection Association's NFPA
497M, ``Manual for Classification of Gases, Vapors and Dusts for
Electrical Equipment in Hazardous (Classified) Locations,'' 1991, or
the National Academy Press's NMAB 353-5, ``Classification of Gases,
Liquids and Volatile Solids Relative to Explosion-Proof Electrical
Equipment,'' 1982. These revisions merely correct errors contained in
the informational electrical hazard class and group column in the table
and represent no change in requirements for the industry.
The electrical hazard class-group of the entries listed below from
table 151.05, part 151 will be corrected as indicated:

This rulemaking also makes other non-substantive editorial changes
and corrections, including a correction to an error contained in the
final rule entitled ``Bulk Hazardous Materials'' published April 11,
1994, in the Federal Register. In revising the section heading to
Sec. 153.560, the Coast Guard inadvertently revised the section number
to incorrectly read as ``Sec. 153.60'' (59 FR 17028). This error is
corrected in this final rule. The correct section number is 153.560.
The Table of ``Upgrade'' Changes below lists all changes by the
IMO, as ``upgrades'' to current entries in the IMO Chemical Codes and
Coast Guard regulations with a brief explanation where helpful.

Because the United States is a party to the International
Convention for the Prevention of Pollution from Ships, 1973 as modified
by the protocol of 1978 relating thereto (MARPOL 73/78), these
amendments are required to ensure that the Coast Guard regulations are
consistent with revisions to IMO's chemical codes, which took effect
July 1, 1994. Accordingly, the Coast Guard finds that good cause exists
under 5 U.S.C. 553(b) to publish this rule without opportunity for
comment. On May 24, 1993, in an appendix to the Bulk Hazardous
Materials NPRM (58 FR 29937), the public was notified of the IMO
revisions that are being adopted into Coast Guard regulations by this
final rule.
Future rulemaking
The IMO reevaluated the Pol. Cat. and ship type of a number of
entries based upon revised Hazard Profiles from the Working Group on
the Evaluation of the Hazards of Harmful Substances Carried by Ships
(EHS), EHS 28 meeting held in February 1993. This action resulted in
several entries in the IMO's Chemical Codes having their Pol. Cat. or
carriage requirements ``downgraded'' or ``upgraded''. All
``downgrades'' have been incorporated into Coast Guard regulations by
the final rule, CGD 92-100 published April 11, 1994. The ``upgrades''
from the EHS 28 meeting will be incorporated into Coast Guard
regulations by a future rulemaking. A new Table of ``Upgrades'', as are
known at this time is set out in Appendix I to this rulemaking for the
information of interested parties.
Regulatory Assessment
This rulemaking is not a significant regulatory action under
section 3(f) of Executive Order 12866 and does not require an
assessment of potential costs and benefits under section 6(a)(3) of
that order. It has not been reviewed by the Office of Management and
Budget under that order. It is not significant under the Department of
Transportation Regulatory Policies and Procedures (44 FR 11040;
February 26, 1979). The Coast Guard expects the economic impact of this
final rule to be so minimal that a full Regulatory Evaluation under
paragraph 10e of the regulatory policies and procedures is unnecessary.
This rulemaking is largely administrative in nature and updates the
chemical tables by adding cargoes recently authorized by the Coast
Guard or added to the IMO Chemical Codes and makes other non-
substantive editorial changes and corrections. Some costs are
associated with the changes instituted by the IMO. Many U.S. flagged
tank ships covered by these regulations are already in compliance with
these requirements which coincide with existing regulatory
requirements.
The Coast Guard has identified costs associated with the
``upgrade'' from open or restricted gauging to closed gauging. However,
because of the marine vapor control systems regulations (final rule CGD
88-102, 55 FR 25396, June 21, 1990), the Coast Guard has reason to
believe that most U.S. tank vessels, barge or ship certificated to
carry any commodity affected by this rulemaking, will have or is having
its gauging refitted to be in compliance with the vapor control
regulations. A sampling of barge operators and tank ship operators
supports this position.
Because of the IMO requirements which ``upgrade'' ``motor fuel
anti-knock compounds'' from the current ship type II to ship type I,
there may be an economic impact on vessels certificated to carry this
material. No U.S. flagged vessels are certificated to carry this
material. World-wide there are six vessels certificated to carry this
commodity, of which four are operated by a U.S. company, the remaining
two are operated by an overseas company. All six vessels are
certificated under foreign flags; four Liberian and two Norwegian.
These ships currently may meet the requirements of ship type I vessels,
in which case, there will be no economic impact. However, the Coast
Guard has no information on these foreign flagged vessels to indicate
whether the ships certificated to carry this material currently meet
those requirements.
Small Entities
Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), the
Coast Guard must consider the economic impact on small entities of a
rule for which a general notice of proposed rulemaking is required.
``Small entities'' may include (1) small businesses and not-for-profit
organizations that are independently owned and operated and are not
dominant in their fields and (2) governmental jurisdictions with
populations of less than 50,000. This rule does not require a general
notice of proposed rulemaking and, therefore, is exempt from the
requirements of the Act. Although this rule is exempt, the Coast Guard
has reviewed it for potential impact on small entities.
This final rule is largely administrative in nature. Some costs are
associated with the IMO requirments implemented by this final rule. As
discussed above, most U.S. flagships that are covered by this
rulemaking are in compliance with this rule due to existing regulatory
requirements.
Therefore, the Coast Guard certifies under section 605(b) of the
Regulatory Flexibility Act (5 U.S.C. 601 et seq.) that this rule will
not have a significant economic impact on a substantial number of small
entities.
Collection of Information
This final rule contains no collection of information requirements
under the Paperwork Reduction Act (44 U.S.C. 3501 et seq.).
Federalism
The Coast Guard has analyzed this rulemaking in accordance with the
principles and criteria contained in Executive Order 12612 and has
determined that this rulemaking does not have sufficient federalism
implications to warrant the preparation of a Federalism Assessment.
This rulemaking is largely administrative in nature and will merely
update current chemical tables in Coast Guard regulations and will have
no Federalism implications. However, the authority to implement the
requirements of this rule has been committed to the Coast Guard by
Federal statutes and the importance of uniform requirements in the
carriage of bulk hazardous cargo aboard ships moving from port to port
requires that the Coast Guard preempt conflicting State and local
requirements in the same subject area.
Environment
The Coast Guard has considered the environmental impact of this
final rule and concluded that, under section 2.B.2 of Commandant
Instruction M16475.1B, this action is categorically excluded from
further environmental documentation. This rulemaking is an
administrative update of current tables to add chemicals already
approved under Coast Guard regulation or international law. Any impact
on the environment will be positive because the carriage requirements
established by the IMO could result in a reduction in maritime
pollution from tankships. A Categorical Exclusion Determination is
available in the docket for inspection or copying where indicated under
``ADDRESSES.''

Appendix to this Final Rule
Note: The following appendix will not appear in the Code of
Federal Regulations.
SUMMARY: The information contained in this appendix is for
informational purposes only, and is intended to provide mariners
with insight into revisions that may be adopted in future
rulelmaking actions. It does not change existing regulations. The
table below lists ``upgrades'' to current entries in the IMO
Chemical Codes and Coast Guard tables and lists that, if adopted by
the IMO as anticipated, would take effect sometime in mid-1997. This
table was prepared from documents from the IMO Evaluation of Hazards
Working Group (BCH), BCH 23 meeting (September 13-17, 1993).
The IMO reevaluated the Pol. Cat. and ship type of a number of
entries based upon decisions reached at the EHS 28 meeting held in
February 1993. The decisions were based on the Group of Experts on
the Scientific Aspects of Marine Pollution (GESAMP) Hazard Profiles
from the Working Group on the Evaluation of the Hazards of Harmful
Substances Carried by Ships (EHS). The reevaluations resulted in
several ``downgrades'' and ``upgrades''. All ``downgrades''
established at that meeting have been incorporated into Coast Guard
regulations by the final rule, CGD 92-100, published April 11, 1994.
These new, and any other ``upgrades'' established in the future
will be included in future Coast Guard rulemaking(s) to coincide
with amendments to the IMO Chemical Codes. As stated above, at this
time, the next set of amendments is scheduled for adoption in mid-
1997.
``Upgrades'' to current entries in the various tables consist of
increased carriage requirements or revised, higher Pol. Cat.'s. The
Coast Guard does not consider a change in Pol. Cat. from a
provisional category, designated by having square brackets ``[ ]''
around it, to a final Pol. Cat. as an ``upgrade'' or ``downgrade''.
It is considered a final assignment and takes effect immediately
upon IMO's removal of provisional status.
All ``upgrades'' as are currently known are addressed in this
appendix.

1. In its continued effort to maintain consistency between the
requirements of the tank ship regulations (part 153) and the
tankbarge (part 151) where applicable, the Coast Guard, in a future
rulemaking, will be changing, modifying or adding carriage
requirements as discussed in paragraphs (a) and (b) below.
(a) In order to conform tank ship and tankbarge requirements,
special requirement 151.50-5 - ``Cargoes having toxic properties''
will be added to the entries in table 151.01 of part 151 of the
tankbarge regulations for the commodities listed below. This is in
conformance with the current special requirement for these
comodities found in tank ship regulations at Sec. 153.525,
``Special requirements for unusually toxic cargoes''.
Acetonitrile
Acrylonitrile
Ammonium hydroxide
Butylamine
Carbon tetrachloride
Crotonaldehyde
Chloroform
Dichlorobenzene
1,1-Dichloropropane
1,2-Dichloropropane
1,3-Dichloropropane
1,3-Dichloropropene
Diisobutylamine
Diisopropylamine
N,N-Dimethylacetamide
Di-n-propylamine
Ethylamine solution (72% or less)
N-Ethylbutylamine
2-Methylpyridine
1,1,2-Trichloroethane
1,2,3-Trichloropropane
Trichloroethylene
Triethylamine
These discrepancies between the special requirements in the tank
ship table and the tankbarge table were identified by the Cargo
Classification Working Group of the Chemical Transportation Advisory
Committee (CTAC) Subcommittee on the Revision of Title 46 CFR part
151. These changes, to be included in a future rulemaking, would
conform the requirements for unusually toxic cargoes in table 151.05
of part 151 with the requirements in table 1 of part 153 for the
same material.
(b) In addition, the entries in table 151.05, part 151 listed
below were identified as having discrepancies between the
requirements for venting, or gauging, or both, as indicated by an
``X'' in the chart below when compared to the tank ship
requirements:

151. The tankbarge requirements for venting and gauging will be
reviewed by the Coast Guard to insure that these requirements meet a
minimum level of safety. The changes will be part of a future
rulemaking to conform the requirements of the two tables.
2. Coal tar. The Coast Guard is considering whether to initiate
a future rulemaking to remove the entry ``coal tar'' from table
30.25-1 and from the list of flammable and combustible bulk liquid
cargoes in parts 30-40, and then adding it to table 151.05 of part
151. The addition of this entry to table 151.05 is consistent with
the inclusion of other members of the coal tar ``family'' of
commodities already in the table because of similar health safety
hazards. This action would also make the tankbarge and tank ship
tables consistent with respect to this family of commodities. The
Coast Guard is coordinating this action with the American Coke and
Coal Chemicals Institute's Task Force on Marine Shipping Regulations
for Coal Tar Products under the guidance of the Chemical
Transportation Advisory Committee (CTAC).
The entry ``coal tar'', and its family members are currently
included in table 1 of part 153, and no action affecting this table
is planned.
3. Hydrogen peroxide (H2O2) solutions. In a future rulemaking,
the Coast Guard will revise the carriage requirements of the two
hydrogen peroxide solution entries in table 1 of part 153, and add
requirements to table 151.05 of part 151. The revision of the tank
ship requirements in table 1 will correct omissions when these
entries were first entered into the table. The addition of these
entries to the tankbarge table will permit carriage of this material
by barge.
