Bulk Solid Hazardous Materials: Harmonization With the

International Maritime Solid Bulk Cargoes (IMSBC) Code

AGENCY: Coast Guard, DHS.

ACTION: Notice of proposed rulemaking.

SUMMARY: The Coast Guard proposes to harmonize its regulations with

International Maritime Organization (IMO) amendments to Chapter VI and

Chapter VII to the International Convention for the Safety of Life at

Sea, 1974, as amended, (SOLAS) that make the International Maritime

Solid Bulk Cargoes (IMSBC) Code mandatory. The amendments require that all vessels subject to SOLAS and carrying bulk solid cargoes other than grain must comply with the IMSBC Code. The Coast Guard proposes to amend its regulations governing the carriage of solid hazardous materials in bulk to allow use of the IMSBC Code as an equivalent form of compliance for all domestic and foreign vessels operating in U.S. navigable waters. Proposed changes to the Coast Guard regulations will also expand the list of solid hazardous materials authorized for bulk transportation by vessel and include special handling procedures based on the IMSBC Code and existing special permits. These proposed changes would reduce the need for the current special permits for the carriage of certain solid hazardous materials in bulk.

III. Background
Summary of Existing Regulations

The Coast Guard regulations governing the carriage of solid hazardous materials in bulk are found in 46 CFR parts 97 and 148. Part 148 prescribes regulations for the transport of solid hazardous materials in bulk by vessel on U.S. navigable waters. Subpart 148.01 includes information on applicability, special permits, and certification. This subpart also includes a list of permitted solid cargoes that may be transported without special permit from the Coast

Guard; the list was last revised in 1984 (49 FR 16794). The list does not cover 30 additional solid cargoes that are now shipped in bulk by vessel and that require special handling procedures to ensure safety in transportation. The Coast Guard issues special permits specifying conditions under which it allows transport of these bulk solid cargoes by vessel.

Subpart 148.02 includes vessel requirements for shipping papers, dangerous cargo manifests (DCMs), and reporting of incidents. Subparts 148.03 and 148.04 include minimum transportation requirements for all bulk solid cargoes subject to Part 148, and special additional requirements for certain material. The special additional requirements are applied to solid cargoes permitted to be carried in bulk by vessel in accordance with Subpart 148.01.
Regulatory History

This rulemaking is based on a previous rulemaking (CGD 87-069), which the Coast Guard closed in 1995. On April 28, 1989, the Coast

Guard published an advance notice of proposed rulemaking (ANPRM) titled

``Marine Transport of Bulk Solid Hazardous Materials'' in the Federal

Register (54 FR 18308). During the 60-day comment period, the Coast

Guard received 16 comment letters on the ANPRM, which we considered in developing a notice of proposed rulemaking (NPRM). The comments did not request a public meeting, and we did not hold one.

On April 12, 1994, the Coast Guard published an NPRM titled

``Carriage of Bulk Solid Materials Requiring Special Handling'' in the

Federal Register (59 FR 17418) with a 90-day comment period. On August 5, 1994, we extended the comment period for 30 days (59 FR 40004). The 1994 NPRM addressed comments received on the ANPRM. The NPRM also included a provision regarding the carriage of coal (proposed in the 1994 NPRM as Sec. 148.240), which was based on a report by the

Chemical Transportation Advisory Committee (CTAC) Subcommittee on Coal

Transportation. That CTAC report is discussed in the 1994 NPRM at 59 FR 17420. In response to the 1994 NPRM, the Coast Guard received 65 letters and communications containing more than 200 comments. No public meeting was requested, and we did not hold one.

On April 13, 1995, the Coast Guard published a notice of termination in the Federal Register (60 FR 18793). At that time, we closed the rulemaking to focus resources on other matters. We resolved those matters and we are now proceeding with the rulemaking. A copy of the 1994 NPRM and the 1995 Termination Notice have been placed in the public docket for reference.

Page 34576

In 2008 and 2009, the CTAC Subcommittee on Solid Bulk Cargoes held several meetings regarding the IMSBC Code and specific requirements for the carriage of all bulk solid cargoes by vessel. Industry provided extensive recommendations during these public meetings, which the Coast

Guard considered and incorporated when developing this proposed rule.

The meetings occurred on April 23, 2008 (73 FR 17369), September 9 and 10, 2008 (73 FR 47202), April 21 and 22, 2009, and August 12, 2009 (74

FR 39090). The rulemaking docket (USCG-2009-0091) contains minutes of these public meetings as well as the subcommittee's final report. The

Coast Guard used CTAC's report in preparing this NPRM.

At the time the Coast Guard published the 1994 NPRM, the international standard for the marine transport of solid materials in bulk was the Code of Safe Practice for Solid Bulk Cargoes (BC Code).

Since the 1994 NPRM, the IMO has updated the BC Code periodically and renamed it the IMSBC Code. Therefore, this proposed rule is similar, but not identical, to that proposed in the 1994 NPRM. The Coast Guard encourages members of the public to comment on this NPRM, even if they may have submitted a similar comment in the 1994 rulemaking.

The period for comment on this NPRM is 30 days. We believe that a 30-day comment period is adequate in light of the long history of this rulemaking and the multiple opportunities for comment. As described in detail above, the public has commented on an ANPRM as well as an NPRM very similar to the rule proposed in this document, and at four public meetings in the last 2 years. In addition, the Coast Guard participated in the development of the IMSBC Code, and held public meetings prior to each meeting with the IMO to give shipping and cargo interests the opportunity to comment on IMO activities (see, e.g., 74 FR 40632, 73 FR 51876, and 72 FR 44213). For these reasons, we believe that a comment period of 30 days is appropriate.
Changes to International Regulations That Led to This Rulemaking

The carriage of hazardous materials in international maritime commerce is now governed by Chapter VII of the International Convention for the Safety of Life at Sea, 1974, as amended (SOLAS). In 1990 and 1991, the IMO amended Chapter VI of SOLAS, which formerly applied only to grain cargoes, to include all bulk solid cargoes. The amended

Chapter VI of SOLAS requires that the master receive written cargo information, that the vessel carry oxygen analysis and gas detection equipment on board when the cargoes to be carried are likely to emit toxic or flammable gases, and that the master possess information regarding the ship's stability and the distribution of cargo after loading.

On January 1, 1994, these amendments became binding for all nations signatory to SOLAS, including the United States. In December, 2008, IMO further amended SOLAS Chapter VI and Chapter VII, to require compliance with the relevant provisions of the IMSBC Code for the carriage of bulk solid cargoes other than grain. This amendment will become binding for all nations signatory to the SOLAS Convention on January 1, 2011.

The IMSBC Code, formerly known as the BC Code, is the international standard for the marine transport of solid materials in bulk. The IMO first issued it in 1965 and has amended it several times since, most recently in 2008. The IMSBC Code provides standards for shippers, vessel operators, and masters to ensure the safe handling and carriage of bulk solid cargoes. Implementation of the IMSBC Code will not become mandatory until January 1, 2011, but several countries have already adopted the Code, in whole or in part, as national regulation.

Countries that are party to SOLAS will require compliance with the

IMSBC Code for all bulk solid shipments occurring in their jurisdiction. Several bulk solid cargoes covered by the IMSBC Code are also regulated by the Coast Guard under 46 CFR part 148, under either the list of permitted cargoes or the terms of a special permit.

The Secretary of Homeland Security delegated to the Coast Guard the authority necessary to conduct this rulemaking, including the authority to carry out the functions and exercise the authorities in 46 U.S.C. 3306 and 5111, and to carry out the functions of 46 U.S.C. 3306(a)(5) and 49 U.S.C. 5101 et seq. relating to the regulation of bulk transportation of hazardous materials loaded or carried on board a vessel without benefit of containers or labels. Under these and other authorities, the Coast Guard proposes in this NPRM regulations that would allow the use of the IMSBC Code as an equivalent form of compliance with 46 CFR part 148 for international shipments originating or concluding in the United States, subject to conditions and limitations.

IV. Discussion of Comments on the 1994 Notice of Proposed Rulemaking

In response to the April 1994 NPRM, the Coast Guard received 65 letters and communications containing more than 200 comments. Those commenting included shippers, carriers, terminal operators, marine surveyors, trade associations, private individuals, and the Canadian

Coast Guard. No public meeting was requested, and we did not hold one.

In this section, we discuss the comments received on the 1994 NPRM, including, where appropriate, instances in which comments led to changes between the 1994 NPRM and this NPRM. In many cases, we no longer have the original comment letters submitted in 1994; instead, we based our discussion of those comments on summaries created in 1994, which we have made available in the docket. Following the discussion of the public comments, we summarize additional changes made to this proposed rule as the result of actions by the Coast Guard, the IMO, and the Pipeline and Hazardous Materials Safety Administration (PHMSA) since publication of the 1994 NPRM.
General Comments

Two comments objected to the rulemaking in general, stating that the regulations are burdensome and unnecessary.

We have regulated shipment of bulk solid hazardous materials for more than 30 years. All of the materials previously regulated and those to be regulated under this rulemaking have been determined through experience and/or scientific investigation to have characteristics that could endanger human life or harm the marine environment. Before participating in any action by IMO to develop the IMSBC Code, the Coast

Guard sought advice from the affected segments of American industry.

The coal industry is a particularly good example. A special working group from American coal and marine transportation interests participated in the development of the international requirements. The adoption of amendments to Chapter VI and Chapter VII of SOLAS require that all vessels subject to SOLAS and carrying bulk solid cargoes other than grain must comply with the IMSBC Code. It is necessary for the

United States to update its regulations to harmonize with SOLAS requirements. Allowing for the use of the IMSBC Code as an equivalent form of compliance with 46 CFR part 148, and reducing the number of special permits requested and issued, will reduce some burden on both the Coast Guard and the shipper. The United States has been, and expects to continue being, a leader in international maritime safety.

Page 34577

One comment noted that the Coast Guard was regulating in an area where each circumstance is different and calls for different measures.

This comment recommended that the Coast Guard require companies conducting potentially risky operations to conduct a systems analysis similar to the process hazards analysis now required by both the

Occupational Safety and Health Administration (OSHA) and the

Environmental Protection Agency (EPA).

We determined that the comment's recommendation transcends the scope of the present rulemaking. None of the materials regulated under the former rules or proposed for regulating by this NPRM have a history of catastrophic events that would put an entire community at risk. Only a few are environmentally hazardous substances of significance. The issue of systems analysis as proposed by the comment would be better addressed under a comprehensive review of the Coast Guard's port safety regulations.

Ten comments proposed that the rules in Part 148 should not apply to unmanned barges in domestic rivers or coastwise service. We agree in part. We revised proposed Sec. 148.1 to exclude unmanned barges transporting potentially dangerous materials (PDM), such as coal and wood chips, from this part except when such a barge is on an international voyage. PDM materials have characteristics of self- heating, flammable/toxic gas emission, or oxygen depletion. These materials pose little danger when transported in open hopper barges.

This part would continue to apply to all unmanned barges transporting bulk materials meeting the hazardous class definitions in 49 CFR

Chapter I, Subchapter C; for example, ammonium nitrate fertilizer and ferrosilicon. The term PDM is functionally equivalent to term

``material hazardous only in bulk'' (MHB), which is used in the IMSBC

Code.
Comments Relating to Specific Provisions 1. Section 97.12-1. Four comments found the applicability statement confusing and the applicability of Subpart 97.12 to foreign flag vessels and barges unclear.

This section has been deleted from the proposed rule. The vessel applicability rules from Part 90 apply. 2. Section 97.12-3. One comment remarked that not all vessels subject to the rules would have masters.

We determined that no change is necessary. Unmanned barges are exempt from Subpart 97.12 and all other vessels have masters. 3. Section 148.3. a. Adjacent space. Two comments questioned the definition of

``adjacent space.'' One asked whether an adjacent space included penetrations, such as cable runs and pipes, in a bulkhead separating a space from a cargo hold, if those penetrations were gas-tight. The other stated that spaces having a high rate of air exchange that negates the potential for the accumulation of toxic or flammable gases should not be considered adjacent spaces.

To the first comment, the Coast Guard explains that if a cable or pipe passes through the common bulkhead or deck in a stuffing tube or packing gland, the space is considered an adjacent space. If a pipe is welded where it passes through the common bulkhead or deck, it is not a penetration for the purposes of this definition.

To the second comment, we point out that the definition of adjacent space relates only to the location of a space in relation to a cargo hold containing bulk solid materials requiring special handling. The atmospheric conditions in the space are not addressed in the definition. Ventilation of adjacent spaces is addressed for specified cargoes. b. Hot-molded briquettes. One comment pointed out that the definition of ``hot-molded briquettes'' is not consistent with the BC

Code (now replaced by the IMSBC Code).

The IMSBC Code defines hot molded direct reduced iron (DRI) as briquettes molded at a temperature of 650 [deg]C or higher that have a density of 5.0 g/cm[sup3] or greater. The 1994 NPRM had stated that DRI briquettes were either molded at a temperature of 650 [deg]C or higher or had a density of 5.0 g/cm[sup3] or greater. In this proposed rule, we have revised the proposed definition to match the IMSBC Code. c. Surface ventilation. One comment asked if the definition of

``surface ventilation'' included both active (fan-induced) and passive

(hatch cover vents) ventilation.

The answer is yes. In this proposed rule, we have expanded the definition accordingly. 4. Section 148.5. One comment supported acceptance of alternative procedures set out in Sec. 148.5. 5. Section 148.8. One comment proposed that Section 4 of the BC

Code (now IMSBC Code) be incorporated by reference. The section deals with assessing the acceptability of consignments for safe shipment.

Section 4 of the IMSBC Code contains provisions for information to be given to the master prior to loading, and retained on board during carriage. This section of the IMSBC Code is incorporated by reference for international shipments under Sec. 148.55 of the proposed rule.

For domestic shipments, equivalent measures are contained in Sec. Sec. 148.60 and 148.70. 6. Section 148.10. a. One comment found the proposed rules ``grossly inadequate'' in how they protect merchant mariners from exposure to hazardous substances. Commenting on footnotes 7, 8, 10, 12, and 15 of proposed

Table 148.10, this comment recommended that the Coast Guard either adopt OSHA standards for personal protective equipment or develop its own equivalent standards.

We recognize that this regulation does not contain all the requirements necessary for a comprehensive health and safety program.

In our Navigation and Vessel Inspection Circular (NVIC) 3-92 of

February 24, 1992, however, we provide the marine industry with guidance for such a program.

In this proposed rule, we have retained requirements for the most important health and safety issues related to the transportation of materials regulated in Part 148. These include general requirements to treat all cargo holds as confined spaces, and specific requirements that are deemed necessary due to unique hazards of certain bulk solid materials. In this proposed rule, a new section, Sec. 148.86, containing requirements for confined space entry has replaced the

``special requirements'' proposed in Sec. Sec. 148.425 and 148.430 in the 1994 NPRM Sec. 1. Also, we have added a definition of ``confined space'' to Sec. 148.3. b. One comment suggested that an entry for ``ammonium nitrate, UN 1942'' be added to Table 148.10.

We agree and we have adjusted this proposed rule accordingly. The footnotes and special requirements in the new entry would be the same as for ammonium nitrate fertilizer, UN 2067. c. Four comments opposed the classification of coal as PDM and/or requested that the transport of coal be removed from the rulemaking.

We did not adopt this request. The IMSBC Code provisions for transport of coal are the result of a U.S. initiative developed with the knowledge, assistance, and concurrence of the U.S. coal industry.

Where the 1994 rulemaking was not in harmony with the IMSBC Code, we have revised this proposed rule accordingly. The burden on the coal industry would be lessened by exempting domestic barge shipments of

PDM, as is provided by this rulemaking.

Page 34578

d. Concerning the list of sections containing special requirements for coal, one comment observed that Sec. Sec. 148.15, 148.80, 148.90, 148.100, 148.110, 148.115, and 148.120 also apply to coal.

Although this is generally true, Sec. 148.15 does not apply to coal; therefore, no change to Table 148.10 is necessary to make reference to this section. The other sections cited by the comment contain general requirements that apply to all commodities listed in the table, and are not specific to coal. e. One comment questioned the applicability to coal of footnote 24 of proposed Table 148.10, cargoes subject to liquefaction, stating that liquefaction cannot occur with coal.

Based on the IMSBC Code and other information available to the

Coast Guard, we believe liquefaction can indeed occur with coal if the coal is in a finely divided form. In order to clarify this, proposed

Sec. 148.450, ``Cargoes subject to liquefaction,'' states that it does not apply to cargoes of coal that have an average particle size of 10 mm (.394 in.) or greater. The average particle size is based on the definition of ``fine-grained materials'' in Appendix 2 of the IMSBC

Code. f. One comment requested that footnote 11, which indicates that petroleum coke is susceptible to spontaneous heating and ignition, be removed from the entry for petroleum coke in Table 148.10. The comment states that this footnote is not appropriate.

We found that the IMSBC Code identifies spontaneous heating and ignition as a characteristic of petroleum coke, and we have left this as a hazardous or potentially dangerous description for petroleum coke. g. One comment opposed classification of sawdust and wood chips as

PDM.

We disagree. The Coast Guard's Bulk Solid Cargoes regulations have listed sawdust as a regulated material since before 1976. Under this proposed rule, we would regulate sawdust as PDM when carried by cargo vessel; it is currently regulated as an Other Regulated Material--Class

C (ORM-C). However, the proposed rule does not apply to domestic barge shipments. The principal hazard associated with these materials, sawdust and wood chips, is oxygen depletion in confined spaces. Since these materials are usually transported domestically in open hopper barges, oxygen depletion is not a significant hazard. h. One comment recommended that an entry for Sulfur, NA 1350,

Hazard Class 9, be added to 49 CFR Table 172.101 to be used for domestic transportation of sulfur.

We agree that this addition would be consistent with the entries for sulfur in 49 CFR Table 172.101. The entry for sulfur that is assigned to NA 1350 may be used only for domestic transportation. The proposed entry for Sulfur UN 1350, Hazard Class 4.1, has been retained for international transportation. The footnotes and special requirements of both entries are the same. 7. Section 148.12. a. This was one of the most controversial provisions of the 1994

NPRM. Seventeen comments objected to this provision on the grounds that it would create a monopoly by naming the National Cargo Bureau, Inc.

(NCB), as the exclusive agency for assisting the Coast Guard in administering Part 148. The comments requested that we authorize other competent entities to assist in the administration of these regulations.

Since 1952, the Coast Guard's hazardous materials regulations

(HMRs) have contained a provision recognizing NCB. As proposed in 1994,

Sec. 148.12 (to replace existing Sec. 148.01-13) granted no monopoly to the NCB, did not require that its services be used, and did not prohibit carriers from employing other surveyors. In this proposed rule, we have retained this section with only minor revisions. b. One comment noted that Sec. 148.12 implies mandatory Coast

Guard inspection of each barge, creating a delay that would have an adverse economic impact.

This is not the case. Proposed Sec. 148.12 in no way mandates inspection of every barge. We have the authority to inspect barges or other vessels to ensure compliance with the regulations, but in practice we do not carry out inspections of 100 percent of the affected vessels. The employment of NCB or any recognized marine surveying organization is voluntary on the part of a vessel operator. 8. Section 148.55. One comment noted that proposed paragraph (b) of this section, by authorizing compliance with international requirements in lieu of compliance with Part 148, may preclude some other regulations in Part 148.

As the rule was proposed in the 1994 NPRM, this would have been true. However, it was not the Coast Guard's intent that this provision should obviate the requirements concerning environmentally hazardous substances or zinc ashes. In this proposed rule, we have revised paragraph (b) of this section to require that these commodities must comply with Part 148 in addition to the IMSBC Code. We are not aware of any other provisions in this rulemaking that are significantly more stringent than the IMSBC Code. 9. Section 148.60. a. One comment recommended that shipping papers include the shipper's and transporter's Hazardous Materials Registration Number.

Under PHMSA regulations at 49 CFR part 107, subpart G, registration is required only for shippers and transporters of certain packaged hazardous materials. Registration is not required for shippers or transporters of bulk materials, including solid materials, liquid chemicals, and compressed gases. Therefore, not all shippers and transporters of bulk solid materials will have Hazardous Materials

Registration Numbers. b. One comment stated that the proposed regulation provided inadequate protection regarding shipment by barge. Because barges do not have masters, there is no one to hold responsible for accepting the commodity.

We point to Sec. 148.2, proposed in this rulemaking, which places the duty to comply with these regulations on ``each master of a vessel, person in charge of a barge, owner, operator, charterer, or agent.'' We propose to revise the definition of ``master'' in Sec. 148.3 to indicate that the person in charge of a barge may perform the functions of a master for the purposes of this proposed rule. We also propose to add the definition of ``person in charge of a barge'' to Sec. 148.3. c. One comment requested that the Coast Guard define the format or document to be used for notification of the master.

We do not intend to impose a format for communications between shipper and carrier. A single format cannot take into account all forms of communication between all types of shippers and carriers.

Documentation should be in a form acceptable to both parties. d. One comment suggested that it may be good practice to have a material safety data sheet (MSDS) address some portions of proposed

Sec. 148.60.

We agree with the comment, but point out that proposed Sec. 148.61 already allows hazardous materials information to be provided in the form of an MSDS. e. One comment observed that, as proposed in the 1994 NPRM, Sec. 148.60(d) negated the requirement for shipping papers for shipments of

PDM, including coal.

In this proposed rule, we have resolved this issue by removing

Page 34579

paragraph (d) of Sec. 148.60. Because of the proposed applicability provisions at Sec. 148.1, shipping papers would be required for all shipments of hazardous materials and PDM by cargo vessel, and by unmanned barge if the barge is on an international voyage. Shipping papers are not required for PDM when transported by barge in domestic transportation. f. One comment stated that the shipping paper requirements for PDM in the 1994 proposal were not clear; this comment proposed that the requirement for shipper advice be dropped.

Shippers' advice to the master is essential for many materials. The shipper has the most knowledge of the characteristics and hazards of the material and therefore can provide the best advice for shipping.

This information most commonly is conveyed through shipping papers and

DCMs. Under SOLAS, shipping papers and a DCM are required for all hazardous cargoes. Therefore, in this proposed rule, we removed the exception for PDM in international commerce. Because of the proposed revision to the applicability provisions at Sec. 148.1, neither shipping papers nor a DCM are needed for shipments of PDM by unmanned barge in domestic transportation. 10. Section 148.62. Two comments did not believe safety would be meaningfully enhanced by a requirement to transfer and maintain aboard an unmanned barge written information on the hazards of these cargoes.

The proposed regulations require that the shipping paper and emergency response information be kept on the tug or towing vessel, or, in the case of a moored barge, in a readily retrievable location. The purpose of this requirement includes the safety of first responders. If an incident should occur on board the barge, it is essential that personnel responding can obtain emergency response information. If the shipper or the master of a vessel or person in charge is not available, this may be the only source of information on the cargo. 11. Section 148.70. a. One comment requested that barges be exempt from the requirement for a DCM.

Under the revised applicability provisions of this proposed rule, barges are exempt from DCM requirements unless they are on an international voyage. On international voyages, barges carrying Class 4 through 9 hazardous materials in bulk must comply with SOLAS and therefore must have a DCM. b. Another comment questioned whether a DCM is required for materials classed as PDM.

The answer is no. A DCM is required only when a cargo vessel (or a barge on an international voyage) transports bulk materials of Hazard

Classes 4 through 9. c. One comment recommended that a DCM be required for unmanned barges.

We partially agree. Under SOLAS, an unmanned barge carrying bulk hazardous materials other than PDM on an international voyage must have a DCM on board. For barges in domestic transportation, however, the information required to be on the DCM is either not applicable or is redundant to information presented on the shipping paper. The shipping paper required on board the towing vessel or on the barge under proposed Sec. 148.60 provides sufficient information. 12. Section 148.80. a. One comment asked whether the definition of ``responsible person'' included members of a ship's crew designated by the master or his deputy and noted that, if so, no changes in current practices are implied.

This definition as referenced by the comment is the intended definition of ``responsible person.'' The responsible person must be a person empowered by the master of a vessel or the owner or operator of a barge to make all decisions relating to his or her specific task and must have the necessary knowledge and experience for that purpose. We have added this definition of ``responsible person'' to proposed Sec. 148.3. b. Another comment asked whether these regulations would require either the vessel or the shipper to provide a ``responsible person'' to supervise the loading.

The answer is yes. The proposed rule requires that a responsible person be assigned by either the master of the vessel or the owner or operator of a barge. 13. Section 148.90. a. Eighteen comments questioned the need for holds to be thoroughly cleaned of the previous cargo when the same cargo is to be loaded again.

We believe that the 1994 NPRM was ambiguously worded with regard to the cleaning of cargo holds. The current proposed rule clarifies that thorough cleaning is required only when the previous cargo is incompatible with the cargo being loaded. Compatibility is determined by reference to the stowage and segregation requirements in Subpart D of Part 148. b. Four comments stated that the requirement that each cargo hold be as dry as practicable was in itself not practical.

The proposed rule clarifies that this requirement applies only to bulk solids that are dangerous when wet or that are subject to liquefaction. c. Two comments expressed the need for shippers to advise masters of Great Lakes vessels regarding stowage factors and trimming, because of the unique design and operating mode of these vessels. According to the comments, the best course of action is to test every coal cargo for methane regardless of information provided by the shipper.

We agree. The IMSBC Code requires that the atmosphere above the cargo in each hold containing coal be regularly monitored for the concentration of methane, oxygen, and carbon monoxide with procedures outlined in Appendix 1. d. Another comment recommended that the requirement to provide information on the chemical properties and related hazards of coal and petroleum coke should be omitted.

We disagree. In the interest of safety, the master of the vessel must be fully informed of the nature of the material to be loaded. The regulations, it should be noted, do not stipulate that the chemical properties and related hazards information must be provided for each shipment. For repetitious shipments by a single shipper of a material whose characteristics remain unchanged, this information need only be provided once and retained on file. 14. Section 148.100. One comment recommended that recording the details of cargo monitoring and gas testing in a separate dedicated book should be allowed to continue. The ship's log need only make reference to such testing or monitoring.

We agree with the comment and revised proposed Sec. 148.100 requiring that the date and time be recorded in the ship's log. The proposed rule requires only that the detailed information be recorded, and does not specifically require that it be recorded in the ship's log. 15. Section 148.110. One comment stated that a cautionary statement referring to 33 CFR part 151 might be appropriate for inclusion in

Sec. 148.110.

We agree. Under 33 CFR part 151, operational and maintenance wastes such as cargo residues and deck sweepings are considered ``garbage.''

When on U.S. territorial seas or inland waters, cargo residues and deck sweepings must be retained on the vessel and disposed of as specified in that part; therefore, we included this information in the proposed

Sec. 148.110. 16. Section 148.150. One comment requested that a provision be added under Sec. 148.150 to read ``sulfur must be

Page 34580

segregated as required in Sec. 148.120 for Class 4.1 materials.''

We agree with the comment and made this revision. 17. Section 148.155. One comment interpreted this section as requiring separation by one complete cargo compartment between two PDM commodities. They doubted that a vessel would be capable of sailing with an empty intermediate cargo compartment without stressing the vessel.

This comment likely refers to proposed Sec. 148.155(d)(2). The separation provision applies only when the temperature of petroleum coke is 55 [deg]C (131 [deg]F) or higher when loaded. The purpose of this requirement is to prevent contact between a bulkhead of a cargo hold containing hot hazardous material and a cargo in an adjacent cargo hold that is sensitive to heat. If it is necessary to transport petroleum coke in a hold adjacent to other hazardous materials, the solution is to not load hot petroleum coke until its temperature decreases to below 55[deg]C. Alternatively, if possible, nonhazardous cargo could be stowed in the intervening hold. 18. Section 148.205. a. One comment stated that the temperature limitations for ammonium nitrate fertilizer should be ensured by monitoring and controlling temperature at the output from the manufacturing process rather than by temperature probes once the material is loaded.

We agree that the temperature of ammonium nitrate fertilizer or any other bulk commodity is best controlled through the manufacturing process. However, only monitoring immediately before loading would ensure that the temperature of the cargo on the vessel is within safe limits. b. One comment asked if the detonation test prescribed by The

Fertilizer Institute was acceptable as an equivalent test under Sec. 148.205(b).

In this proposed rule this test has not been added to the list of allowable tests because it is no longer being maintained by The

Fertilizer Institute. Therefore, the detonation test prescribed by The

Fertilizer Institute is not acceptable as an equivalent. c. One comment stated that Sec. 148.205(c)(1) is a reasonable requirement provided it does not mean that each load offered for shipment has to be tested. According to the comment, test data on file supporting the classification by the manufacturer should be sufficient.

This proposed provision does not imply that testing is required for each shipment as long as the chemical composition of the material being shipped has not changed. d. One comment noted that this section is deficient because it refers only to the ``master'' when the vessel may be a barge.

To clarify the applicability of this and similar provisions, we proposed to revise the definition of ``master'' in Sec. 148.3 to include the ``person in charge of a barge,'' and add a definition of

``person in charge of a barge'' to that section. e. One comment questioned the prohibition on fuel oil transfer during loading of ammonium nitrate fertilizers. This comment saw no reason why internal fuel transfers should not be permitted.

The purpose of prohibiting bunkering and fuel transfers during the handling of ammonium nitrate and ammonium nitrate fertilizers is to preclude any possibility of forming an explosive mixture through the contamination of the ammonium nitrate. This prohibition does not extend to transfers of fuel on board the vessel through the vessel's fixed piping system. We have reworded the section to clarify this. 19. Section 148.225. One comment recommended that Sec. Sec. 148.225 and 148.315 address the proper disposal of residue that has been ``hosed down'' or ``washed down with fresh water.'' Another similar comment recommended that Sec. 148.315 should address proper disposal of sulfur residue that has been ``hosed down'' or ``washed down with fresh water.''

Although the provision for washing down with fresh water is a direct quotation from the IMSBC Code, we recognize that it conflicts with Annex V of The International Convention for the Prevention of

Pollution from Ships (MARPOL 73/78) and 33 CFR part 151. Instead, in these sections, we propose to refer to 33 CFR parts 151.55 through 151.77. 20. Section 148.240. a. One comment believed there should be some discrimination between supply and exhaust fans in determining which must be ``safe for use in an explosive gas atmosphere.'' The comment recommended that all existing fans should be ``grandfathered.''

We disagree. Both intake and exhaust fans must be explosion-proof for two reasons. First, ventilation fans on board a vessel are often dual purpose, serving as both intake and exhaust. Second, pockets of gas may accumulate within the housings of both intake and exhaust fans during periods of non-use, creating the possibility of explosion. b. Two comments expressed an objection to any broad-brush statement classifying all coals as hazardous material.

We support the determination by the IMO that, while some coals are more hazardous than others, all have the potential to be hazardous. We note that the U.S. coal industry was represented on the working group that recommended provisions eventually included in the IMSBC Code. c. One comment remarked that the requirements for coal were different and less demanding than the current recommendations contained in the BC Code (now the IMSBC Code).

Although phrased differently from the IMSBC Code, the proposed provisions of this chapter concerning coal (not limited to Sec. 148.240) are neither different nor less demanding than those of the

IMSBC Code. d. Another comment proposed that some recognition be shown for the unique construction of the Great Lakes self-unloading vessel.

We accept the fact that Great Lakes vessels may have certain unique features. However, they are exceptions to the general case addressed in these regulations. If owners/operators of Great Lakes vessels cannot comply with this proposed rule, but can provide equivalent safety through alternative means, they may take advantage of the alternative procedures provisions of Sec. 148.5. e. One comment found Sec. 148.240(a) not specific enough to establish the types of electrical fittings that are required.

We determined that 46 CFR part 111, subpart 111.105, is sufficient in clarity. An item of electrical equipment must be tested or approved in order to comply with IEC 79 series publications. The specific requirements are stated in 111.105-7(a) and (b) and a reference is made to this section in 148.240. f. Another comment noted that Sec. 148.240(a) did not apply to adjacent spaces because Sec. 148.18(b) recognized that such spaces may have electrical equipment that is not certified safe for use in an explosive gas atmosphere.

This comment is correct. Paragraph Sec. 148.240(a) has been revised so that it refers only to electrical equipment in cargo holds. g. Fifteen comments expressed very serious objections to the provision that the temperature of coal at the time of loading not exceed 41 [deg]C (105 [deg]F), or 15 [deg]C (27 [deg]F) above the ambient temperature.

We agree with the comments. The temperature requirements in the 1994 NPRM were not consistent with the IMSBC Code and have been removed from this proposed rule.

Page 34581

h. Three comments stated that the wording of the requirement for trimming, i.e., ``reasonably level,'' was subject to various interpretations. They recommended that the subjective nature of this section be eliminated by incorporating some quantitative factor, such as a maximum height of the peak of the pile expressed as a percentage of the vessel's beam.

We recognize the subjective nature of this provision but find it to be impractical to impose an arbitrary quantitative standard for

``level.'' We have therefore removed this language from the proposed rule. The shipper will be responsible for providing trimming information in accordance with the new proposed shipping paper requirements. i. Two comments observed that Sec. 148.240(c)(1) provided no definition of ``sealed'', but advised that self-unloading vessels cannot meet this sort of ``sealing'' requirement in all cases. The comments noted that a number of obvious exemptions would be necessary.

We find that the concept of ``sealed'' requires no regulatory definition. The purpose of sealing the accesses and hatches is to prevent the escape of methane from the hold into other spaces on the vessel. This paragraph has been revised to clarify that, because of their design, the unloading gates on self-unloading vessels are not required to be sealed. j. One comment found the 1994 NPRM unclear as to the meaning of the word ``casing,'' and assumed that this refers to access trunks.

We agree. ``Casing'' is the term employed by the IMSBC Code. By common definition, a ``casing'' is the metal enclosure around a space such as an ``access trunk.'' To eliminate confusion, the word

``casing'' has been removed in this proposed rule. k. One comment noted that there was no reference to the tunnel spaces on self-unloading vessels in the section on coal, and suggested they be included in Sec. 148.240(c)(2).

We have adopted this suggestion in the proposed rule. l. Three comments inquired as to what specifically are ``hot areas'' and what is considered adequate ventilation.

We agree that the use of the term ``hot areas'' in the 1994 NPRM was vague, and we have deleted it from this rulemaking.

In the context of Sec. 148.240(c)(2), adequate ventilation means an air exchange that prevents an accumulation of gas that may be harmful to personnel in working spaces. The ventilation may be natural or mechanical and should be commensurate with the risk of exposure of the space to harmful gases.

In the context of Sec. 148.240(c)(3), adequate ventilation means surface ventilation as defined in Sec. 148.240(f). Ventilation has been defined in the definition section, Sec. 148.3. m. One comment stated that paragraph (d) of this section was redundant by virtue of paragraphs (e), (f), and (i).

We do not agree. Paragraph (d) states a general prohibition on ventilation applicable to all shipments of coal. Paragraph (e) requires the temperature of coal, known to be, or suspected of being, susceptible to self-heating, to be monitored. Paragraph (f) provides an exception to paragraph (d) for coals that generate methane. Paragraph

(i) prescribes that the atmosphere in a hold containing a coal described in paragraph (e) must be monitored for carbon monoxide. There is no redundancy between paragraph (d) and any other paragraph or combination of paragraphs. n. One comment asserted that the requirement to provide characteristics of the cargo is the responsibility of the shipper or his appointed agent, and objected to the reference in the 1994 NPRM to information about the cargo possessed by the terminal operator and/or vessel operator. Another comment noted that the requirement to monitor coal temperatures before loading should be the responsibility of the shipper. Three other comments stated the view that shippers at times may find it difficult or impossible to obtain the required information.

These comments stated that shippers should not be liable for information they do not have.

In response to all of these comments, the Coast Guard replies that someone in the transportation chain must accept responsibility for the condition of a material to be loaded aboard a vessel. Logically, the primary responsibility resides with the person who offers the material for shipment. This person is responsible for knowing the specific types of cargoes being shipped and their hazardous characteristics. This responsibility does not absolve the terminal operator, who may have information about cargoes obtained through experience or observation, from an obligation to pass such information on to the master, nor does it absolve the master, who has the final responsibility for the safety of his vessel. This proposed rule clarifies that the master is responsible for monitoring the temperature of the coal. o. Several comments requested clarification as to what triggers the requirement for ventilation of the cargo space. Three comments stated that the term ``freshly mined'' was a subjective judgment and needed to be clarified. One comment requested clarification of what ``history'' would trigger the ventilation requirements for coal.

This section has been revised in the proposed rule to emphasize the coal's potential for emitting methane as the trigger for requiring ventilation of the cargo space. p. One comment requested that temperature monitoring be waived with respect to coal stored in rail cars before loading.

As amended, the proposed rule does not specifically require monitoring the temperature of coal that is stored in rail cars before it is loaded. q. One commenter asked if there is a specific standard for electrical equipment and cables in a hold containing coal, to ensure that they are suitable for use in a potentially explosive atmosphere.

Proposed Sec. 148.240(g) specifies that the electrical equipment, and by implication its associated fittings, must comply with 46 CFR 111.105, which applies to installation of electrical equipment in hazardous locations. r. One comment noted that the meaning of the expression ``may not be de-energized'' was not clear, and asked whether this statement was prohibitive or permissive.

According to Federal Register drafting conventions, the term ``may not'' or ``No person may'' always implies a prohibition. However, we have rephrased this paragraph for clarity. s. Two comments recommended that electrical equipment in adjacent spaces be allowed to meet then-current Coast Guard requirements as long as these spaces are periodically monitored for the presence of explosive gas.

Under 46 CFR 111.105-35, existing electrical equipment in cargo holds containing coal must now be suitable for use in an explosive gas atmosphere. In adjacent spaces, electrical equipment may be suitable for use in nonhazardous atmospheres provided such equipment is de- energized if the concentration of flammable gas in the space reaches a dangerous level. Because this proposed rule introduces no new requirements, there is no need to ``grandfather'' existing installations. t. One comment questioned the exception from gas emission monitoring for voyages of 72 hours or less, noting that all research data indicates that methane has the potential to leak from coal immediately and that occurrences of this sort have resulted in several accidents.

This exception was included in the 1994 NPRM to account for vessels

Page 34582

operating on the Great Lakes. The Coast Guard recognized the merit of the comment and removed the exception from this proposed rule. u. One comment assumed that opening a ``booby hatch'' or vent pipe would not be construed as ``opening the cargo hatches or entering the cargo hold.''

The comment's assumption is correct. v. Three comments noted that it had been the Chemical

Transportation Advisory Committee (CTAC) Subcommittee's intent to exempt unmanned barges from all requirements to test the atmosphere above the coal.

The Coast Guard has proposed to exempt unmanned barges that are carrying any PDM, including coal, from the applicability of this part unless the barges are on an international voyage. w. Two comments noted that, for coal, the procedure in this section for taking pre-loading temperature readings would not always be effective in determining the true status of the stockpile or cargo.

Additionally, they questioned the absence of a provision for continuous electronic (infrared) temperature monitoring, a procedure that is available at some export terminals and that has been proven effective and reliable.

We removed the pre-loading temperature limitations for coal. As a means of monitoring the temperature increase for self-heating coal in the cargo hold of a vessel, we believe the procedure outlined in Sec. 148.240(e) is satisfactory. The Coast Guard does not discount continuous electronic (infrared) temperature monitoring but has not had an opportunity to assess its equivalence to the method specified.

Anyone wishing to use continuous electronic monitoring may request authorization under Sec. 148.5. 21. Section 148.245. a. Two comments noted that the procedures for loading DRI and metal sulfide concentrates in rain or snow were not addressed. They proposed that the rule include detailed procedures for monitoring rainfall and calculating the resulting moisture content, and provisions for communicating this information with the vessel master and terminal.

The Code of Federal Regulations (CFR) cannot serve as a detailed instruction manual for safe handling and loading of cargoes. It is the shipper's responsibility to provide DRI to the master of the vessel in an acceptable condition. Section 148.245.3(c) prohibits acceptance for transport of DRI or cold-molded briquettes that are wet or are known to have been wetted. How this condition is achieved and maintained is left to the shipper's good judgment. b. One commenter felt that Sec. 148.250(d), which prohibits the loading of DRI hot-molded briquettes during periods of rain or snow, was overstated.

We do not agree with this comment. This prohibition is a precautionary measure for keeping cargoes as dry as practicable. When

DRI hot-molded briquettes are exposed to water, they react, releasing hydrogen that initiates self-heating of the cargo. As seen in several incidents over the past years, this self-heating can ultimately lead to auto ignition of the cargo, causing a fire or an explosion within the hold and endangering the life of the crew. c. One comment requested a definition of ``short international voyage.''

After further review, we have removed this terminology from the proposed rule. d. Another comment stated that while this section offers protection to radar and RDF scanners on board the vessel transporting DRI, it fails to offer any protection to the crew, adjacent property owners, etc., from the same dust which would damage the radar.

The Coast Guard's statutory mandate is to protect life and property at sea and to assure preservation of the marine environment. A ship's navigation systems are vital to such protection. Under this rulemaking and OSHA regulations, crewmembers and other persons engaged in cargo handling operations must wear protective clothing and respiratory devices when handling dusty cargoes. The protection of adjacent property and persons not employed by the terminal or the carrier is under the purview of EPA air pollution regulations or local statutes and is beyond the scope of this project. If cargo is appropriately loaded and shipped, the amount of dust released into the environment should be minimal. 22. Section 148.265(g). One comment felt that the requirement to take and record the temperature of fish meal or fish scrap three times a day during a voyage was particularly onerous for unmanned barges.

We agree that taking the temperature three times a day is impractical on an unmanned barge, especially when that barge is part of a multi-barge tow. The proposed rule excludes unmanned barges from the temperature-measurement requirement. 23. Section 148.270. One comment found Sec. 148.270(d) misleading and thought that it might exceed Coast Guard authority.

What specifically was ``misleading'' was not stated. However, this provision does not exceed Coast Guard authority. It merely directs those persons responsible for loading or unloading a vessel to take all reasonable precautions to prevent dispersal of a hazardous substance into the environment, and to report any spill to the National Response

Center in accordance with EPA regulations. In the proposed rule, the final sentence has been revised to refer to the ``garbage'' disposal requirements of 33 CFR part 151. 24. Section 148.285. a. One comment asked the Coast Guard to advise on the format or type of document to be used for notifications to the master of the vessel.

We do not intend to impose a format for communications between shipper and carrier. Documentation should be in a form acceptable to both parties. The language of notification to the master has been removed from this section because that information is already contained in the proposed Sec. 148.60. b. One comment stated that if the sampling of metal sulfide concentrates is not conducted correctly, and, in fact, is not representative of the entire consignment at the time of shipment, then the test procedures may show the cargo safe to transport when this is not the case.

The statement is correct. We expect the information a shipper provides to the master to be both accurate and detailed. 25. Section 148.295. One comment noted that the 1994 NPRM Sec. 148.295 made no mention of the self-heating or spontaneous ignition characteristic of petroleum coke, despite a reference to it in the hazardous or potentially dangerous characteristic column of Table 148.10, footnote 10, found in Sec. 148.11.

This comment is correct. Text has been added to 148.295(g) regarding spontaneous heating of this cargo and the necessity of temperature monitoring during transport. 26. Section 148.310. a. One comment suggested removing seed cake identification numbers

UN 1386 and UN 2217 from the rule.

We have not accepted this suggestion. The United Nations Committee of Experts and the IMO recognize seed cake as a material that may self- heat and, if containing an excessive amount of oil, may be spontaneously combustible. Further, when transported in packages, this commodity is regulated as a hazardous material of Class 4.2 in all modes under PHMSA regulations at 49 CFR Chapter I, Subchapter C.

Page 34583

b. One comment recommended that the Coast Guard amend the rule to be consistent with long-established industry standards for seed cake.

Two comments proposed that the exemption from Special Permit requirements not be limited to solvent-extracted rapeseed meal, pellets, and soya bean meal, but should be extended to other types of seed cake if they meet the prescribed oil and moisture content levels.

A fourth comment requested that the total oil and moisture requirement for cottonseed meal be raised to a maximum of 6 percent.

The criteria for seed cake, UN 1386, are based on the established criteria for classification of hazardous materials as contained in

Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) and the

United Nations Recommendations on the Transport of Dangerous Goods.

Exemptions that were granted to rapeseed meal, pellets, and soya bean meal were based on testing conducted on a world-wide basis that showed these specific products, with varying moisture content, did not qualify as hazardous materials. The oil and moisture requirement for cottonseed meal could possibly be amended if tests are conducted using approved methods and the results show that it is not dangerous. If the seed cake industry wishes to have certain materials deregulated when transported in bulk, they may petition the Coast Guard following the process in 33

CFR 1.05-20. 27. Section 148.325. a. Two comments requested that sawdust and wood chips not be included in these regulations.

Sawdust and wood chips, which are classed as PDM, would not be regulated when transported domestically in unmanned barges. However, the regulations would continue to apply to sawdust and wood chips transported by cargo vessel in international commerce. b. One comment requested that the Coast Guard clarify that having hatch covers completely open when loading wood chips would negate the need for self-contained breathing apparatus (SCBA).

No change to the rule is necessary. Under this rule, SCBA is required for entry into confined spaces containing sawdust or wood chips unless the atmosphere in the space has been tested and determined to contain sufficient oxygen to support life. In an emergency when testing is not possible, entry into an unventilated space is permitted only when wearing SCBA. Loading operations are not an emergency. If the cargo hold to be loaded with wood chips has been opened and ventilated, and has been determined to be safe for human occupancy, there is no reason for a worker engaged in loading operations to have to wear SCBA. 28. Section 148.15. Another comment proposed that the Coast Guard establish a fee schedule to issue special permits.

The Coast Guard does not charge a fee for special permits and does not plan to do so. 29. Section 148.405. One comment recommended that the Coast Guard recognize hot work practices for individual companies; specifically, approval of hot work by the Chief Engineer.

No change to the rule is needed. Hot work may be authorized by the vessel's master, which by definition includes ``an authorized representative of the master.'' A ship's officer, such as the Chief

Engineer, would fall under this definition of master as proposed in

Sec. 148.3. 30. Section 148.407. Three comments stated that it would be impractical and unnecessary to prohibit smoking anywhere on a vessel at any time.

We agree with the comments. In this proposed rule, smoking is prohibited on the weather deck of the vessel during loading and unloading. At all times while cargo is on board, smoking is prohibited in adjacent spaces and in the vicinity of hatch covers, ventilator outlets, and other accesses to the hold containing the cargo. 31. Section 148.410. Two comments questioned the need for a shore- supplied fire main and also the need for fresh water. The ship's supply, they stated, is more reliable, particularly in cold weather.

We agree that the requirement proposed in 1994 exceeds both the

IMSBC Code and recommended industry practice. We have removed from this proposed rule the requirement for fresh water from a shore source. 32. Section 148.415. a. One comment noted that there are no requirements for the gas and oxygen analyzers to be calibrated at specified intervals.

In this proposed rule, we have added a provision to Sec. Sec. 148.415 and 148.85 specifying that the gas analyzing equipment must be calibrated in accordance with the manufacturer's instructions. b. One comment stated that there was no sustainable justification for exempting unmanned barges from these requirements.

We disagree and believe there is ample reason to exclude unmanned barges from the requirement to have flammable gas analyzers on board.

First, the proposed rule does not apply to barges carrying PDM, except when the barges are on an international voyage. In domestic transportation, these materials are normally carried in open hopper barges, in which gases emitted by the material would be unlikely to reach flammable concentrations. Second, for barges carrying cargoes other than PDM, it would be impractical and expensive to require a gas analyzer and tubes on each barge. An unmanned barge is not likely to have a safe and secure place to stow such delicate and sensitive devices. Finally, there is no reason for the crew of a towing vessel to enter the cargo space of a barge while underway. Apart from the potential danger to personnel working on the deck of a barge in a typical multi-barge tow, it would be difficult, if not impossible, to remove the hatch covers to gain access for entry. 33. Section 148.430. One comment agreed with Sec. 148.430 as proposed in the 1994 NPRM, but noted that, in some cases, it may mean providing some additional SCBA units.

In this proposed rule, we have removed Sec. 148.430 and incorporated its provisions into Sec. 148.85. The substance of the observation is correct: At least two SCBA units are required under proposed Sec. 148.85 and vessels may carry more if they deem it is necessary. 34. Section 148.450. One comment objected to the inclusion of coal as a cargo subject to liquefaction, because liquefaction as a practical occurrence cannot occur with coal.

This issue was addressed earlier under a comment on the entry for coal in Table 148.10. Liquefaction can occur in a cargo of coal consisting of fine-grained particles. In this proposed rule, this section has been revised to specify the maximum particle size of coal to which the section applies.
Changes Between the 1994 NPRM and This NPRM, Not Prompted by

Specific Comments 1. Section 148.3. We added the definition of ``threshold limit value'' (TLV), and based the definition on that used by the American

Conference of Governmental Industrial Hygienists (ACGIH). 2. Section 148.10. To conform to recent amendments to the IMSBC

Code, we changed the material description ``aluminum processing byproducts'' to ``aluminum smelting byproducts or aluminum remelting byproducts.'' For the same reason, we added to Table 148.10 the following language under ``Characteristics'' at the entry for silicomanganese: ``With known hazard profile or known to evolve gases.

With silicon content of 25 percent or more.''

Page 34584

Additionally, we added entries for peat moss and ferrous sulfate to

Table 148.10 to conform to recent addition to the IMSBC Code. 3. Section 148.15. We propose to set the maximum term of validity for Coast Guard special permits to 4 years. This would reduce the paperwork burden for applicants for Coast Guard special permits, and would reduce the Coast Guard's administrative burden. 4. Section 148.145. Paragraphs (b) and (c) of this section, as they appeared in the 1994 NPRM, were not stowage or segregation requirements, which this section addresses. We have transferred these provisions to Sec. 148.300. 5. Section 148.240. To reflect a recent decision by the IMO, we revised paragraphs (e), (h), (i), and (j) to permit the monitoring of carbon monoxide emissions as an alternative means of determining rising temperature in a cargo of self-heating coal. Also, we lowered the gas emission threshold at which corrective action must be initiated from 30 percent to 20 percent. 6. Section 148.242. This new section contains special carriage and handling requirements for copra, based on the provisions of the IMSBC

Code. 7. Section 148.265. Coast Guard Special Permit 14-95 authorizes treating fishmeal with a tocopherol (vitamin E) based liquid antioxidant in lieu of the antioxidants specified in the former regulations. Paragraphs (c) and (e) of this section have been revised to include this practice. 8. Section 148.290. This new section contains special carriage and handling provisions for peat moss, based on the provisions of the IMSBC

Code. 9. Section 148.300. On September 28, 1995, the U.S. Department of

Transportation Research and Special Programs Administration (now PHMSA) published a rulemaking in Docket HM-169A that made their regulations at

Title 49 of the CFR governing the transport of radioactive materials compatible with the regulations of the International Atomic Energy

Agency (IAEA). Because 49 CFR 173.403 now contains a definition of

``Surface Contaminated Object'' (SCO-I), this definition need not appear in Coast Guard regulations. Consequently, the term ``Surface

Contaminated Object'' is defined in Sec. 148.300 by reference to 49

CFR 173.403.

V. Discussion of Proposed Rule

The proposed rule would expand the list of materials that may be transported in bulk without applying for a special permit and would detail the special handling requirements. The new list aligns the CFR with mandatory international code, including requirements in Chapter VI and Chapter VII of SOLAS. The proposed rule includes materials already listed in the IMSBC Code and adds materials that have a safe transport history under existing Coast Guard special permits. The proposed rule also eliminates applications and renewals for most special permits now required when carrying materials regulated under this part.

This rulemaking would add 21 new materials to 46 CFR part 148. Some of these materials are covered by the IMSBC Code, some are covered by the HMR (49 CFR chapter I, subchapter C), and some are currently subject to Coast Guard special permits.
Proposed Changes to Part 97

This proposed rule would add a definition of ``bulk solid cargo'' and revise Subpart 97.12 to clarify that the subpart applies to bulk solid cargoes in general, rather than only to ores and ore concentrates. The new proposed rule also clarifies that this section does not apply to grain, as was the original intent of this part, although this was not specified. Further, existing Sec. 97.12-5, which has not been revised since 1965, references a manual that was the predecessor of the IMSBC Code and is no longer in print. The proposed rule eliminates that reference and refers the reader to Part 148 as a source of information for complying with the requirement to provide guidance on safe loading and stowage to the master.

We have also added new proposed Sec. 97.12-5 on liquefaction in order to bring forward the requirements contained in Sec. 148.450 and apply them to all cargoes that are prone to liquefaction. We also propose to modify Sec. 97.55-1 to apply to any bulk solid cargo to which Sec. 148.435 applies.

In the proposed rule we have updated the authority citation for

Part 97 to include 46 U.S.C. 5111 regarding the provision of loading information to the master or individual in charge of the vessel.
Proposed Changes to Part 148

We propose to revise the title of 46 CFR part 148 to read

``Carriage of Bulk Solid Materials that Require Special Handling.'' We propose to update the authority citation for Part 148 to include 33

U.S.C. 1602 and Executive Order 12234 regarding international regulations, as well as 46 U.S.C. 3306 and 5111 regarding regulation of inspected vessels and provision of loading information to the master or individual in charge of the vessel.

We propose to divide Part 148 into six subparts. Within those subparts, the proposed rule reorganizes and renumbers existing sections and adds new sections. We discuss these changes in detail below. 1. Proposed Subpart A--General

The first 12 sections of the revised Part 148 would include general information applicable to the entire Part. We propose to revise the applicability section (formerly Sec. 148.01-1, now proposed Sec. 148.1) to align with the IMSBC Code. Specifically, this change would apply Part 148 to all foreign-flag and U.S.-flag vessels operating in

U.S. waters. The proposed regulations would also apply to all classes of vessels that transport bulk solid cargoes, including unmanned barges and barge-carrying vessels. The regulations would not apply to unmanned barges when carrying cargoes classed as PDM in domestic transportation.

We propose to add a new ``responsibility and compliance'' section at Sec. 148.2, making the vessel master, person in charge of a barge, owner, operator, charterer, or agent responsible for compliance with this part.

We propose to add a new ``definitions'' section at Sec. 148.3.

This section would contain definitions that currently are located throughout Part 148, as well as new definitions that were included for clarity and consistency with the IMSBC Code, including ``away from,''

``Bulk Cargo Shipping Name,'' ``compartment,'' ``confined space,''

``domestic voyage,'' and ``hazard class.'' We also propose to revise the definition of ``bulk'' for clarity and consistency with the IMSBC

Code.

We propose to add a new ``alternative procedures'' section at Sec. 148.5 that outlines the procedures for requesting permission to use alternative procedures, including exemptions to the IMSBC Code, in place of any requirement of this part. We propose to revise the section on permitted cargoes (formerly Sec. 148.01-7, now proposed Sec. 148.10 and Table 148.10) to improve usability and add additional bulk solid cargoes that appear in the IMSBC Code or are authorized under a

Coast Guard special permit. In revising the table, the Coast Guard proposes to add 4 additional columns describing: the identification number; a reference to the preferred BCSN, if needed; cargo characteristics; and the applicable CFR sections containing detailed special requirements for transporting that material. These revisions would make it easier to determine the exact

Page 34585

requirements for carriage of each approved material.

In Table 148.10, the entry for ``aluminum dross, class PDM'' would read ``aluminum processing byproducts or aluminum re-melting byproducts, UN 3170, Class 4.3,'' and the entry for ``zinc ashes, dross, residues and skimmings'' would read ``zinc ashes, UN 1435, Class 4.3.'' These changes reflect reclassification of the materials by the

United Nations Committee of Experts on the Transport of Dangerous

Goods. In addition, the revised table would add the following to the list of permitted cargoes, to maintain consistency with the IMSBC Code and current Coast Guard special permits: aluminum ferrosilicon powder; aluminum silicon powder, uncoated, brown coal briquettes; castor beans; coal; DRI (A); DRI (B); environmentally hazardous substances, solid, n.o.s.; ferrous sulfate, fluorospar; iron oxide, spent, or iron sponge, spent; linted cotton seed; magnesia, unslaked; metal sulfide concentrates; peat moss with moisture content of more than 65 percent by weight; pitch prill; pyrites, calcined; seed cake; silicomanganese with silicon content of 25 percent or more; vanadium ore; and wood chips, wood pellets, and wood pulp pellets.

We further propose to add a new section on hazardous or potentially dangerous characteristics at Sec. 148.11. This section would incorporate information currently contained in column 3 of the table of permitted cargoes. The new section would set forth the meaning of the

``hazardous or potentially dangerous characteristics'' codes given in the revised Table 148.10. This includes code 27, a reference to the

Certain Dangerous Cargoes (CDC) regulations found in 33 CFR 160.204, that apply to ammonium nitrate.

Finally, we propose to renumber the existing Sec. 148.01-13,

``Assignment and certification,'' as Sec. 148.12. 2. Proposed Subpart B--Special Permits

As proposed, Subpart B would set the guidelines for petitions and use of special permits. The proposed revisions to Subpart A should greatly reduce the need for special permits. However, in the event a person wishes to ship a bulk solid material not listed in Table 148.10, the proposed Subpart B allows that person to petition for authorization from the Coast Guard. The revised process for requesting a special permit remains substantively similar to the existing process, but places more responsibility on the shipper to determine the appropriate conditions of carriage. The proposed Subpart B also clarifies who must apply for a special permit, what information is required to obtain a special permit, what activities are covered by a special permit, how long a special permit remains valid, and how to obtain copies of special permits. These proposed sections are more detailed than the current regulations, and are designed to resolve recurring misunderstandings concerning the applicability of the special permit.

In addition, requiring applicants to submit more detailed information about the material carried would greatly decrease the amount of research time needed by the Coast Guard when processing requests for special permits.

Included within the proposed Subpart B is a revision of existing

Sec. 148.01-11 designed to simplify the standard conditions contained in special permits, and to renumber it as Sec. Sec. 148.15 through 148.30. In addition, the Coast Guard proposes to remove the current

Sec. 148.01-11(b)(1) because it describes requirements imposed by special permits. 3. Proposed Subpart C--Minimum Transportation Requirements

As proposed, Subpart C would outline minimum transportation requirements for cargoes subject to this chapter, including temperature readings, shipping paper requirements, emergency response information,

DCMs, preparation and supervision of cargo transfers, confined space entry and equipment, preparations for loading, procedures after unloading, log book entries, and incident reports.

The Coast Guard proposes to clarify the proper conduct of temperature readings (formerly Sec. 148.03-7, now proposed Sec. 148.51), and to require log book entries (proposed Sec. 148.90) to record each temperature measurement and each required test for toxic or flammable gases.

The Coast Guard also proposes to revise shipping paper requirements

(formerly Sec. 148.02-1, now Sec. 148.60) to align with the IMSBC

Code while requiring the shipping papers be provided in English. With regard to emergency response information, the Coast Guard proposes new

Sec. 148.61 requiring that the shipper of a material listed in Table 148.10 provide the master or his representative with appropriate emergency response information, including preliminary first aid measures and emergency procedures to be carried out in the event of an incident or fire involving the cargo. Provision of an MSDS would satisfy this requirement.

With regard to DCMs (formerly Sec. 148.02-3, now proposed

Sec. Sec. 148.70 through 148.72), the Coast Guard proposes to revise the requirements for carriage and contents of the DCM. As proposed, the

DCM requirements would not apply to unmanned barges not on international voyages.

With regard to confined space entry and equipment, the Coast Guard proposes new Sec. 148.85, which would require that vessels, with the exception of unmanned barges, that carry a material listed in Table 148.10 also carry equipment capable of measuring atmospheric oxygen and at least two approved SCBA that each have at least a 30-minute air supply. Proposed Sec. 148.86 would prohibit entry into a confined space unless the space has been tested to ensure there is sufficient oxygen to support life; in case of emergency, a person may enter a confined space without testing it if that person is wearing a SCBA, suitable protective clothing as necessary, and a wire rope safety line tended by a trained person outside the space, and if the entry is supervised by a responsible person.

With regard to procedures to be followed after unloading, the Coast

Guard proposes to renumber existing Sec. 148.03-13 as Sec. 148.110 and revise it to require retention and proper disposal of cargo- associated wastes, cargo residue, and deck sweepings when in U.S. territorial seas or inland waters.

In addition, the Coast Guard proposes to add new Sec. 148.55

``International Shipments,'' which would enable the use of the IMSBC

Code as an alternate method of compliance with Part 148, as long as the bulk solid material being transported is subject to the requirements of the IMSBC Code. However, transport of zinc ashes must comply with Part 148 because zinc ashes pose environmental hazards that would not otherwise be addressed. In addition, the proposed Sec. 148.55 would include new paragraphs (b)(3) and (b)(4) to require Coast Guard approval of any exemption granted by another government before reliance on that exemption for compliance with Part 148. Finally, Sec. 148.55 would make the person importing a bulk solid responsible for ensuring the foreign shipper is aware of U.S. requirements. 4. Proposed Subpart D--Stowage and Segregation

Proposed Subpart D would set stowage and segregation requirements for cargoes. These proposed requirements are in addition to the minimum requirements for all materials and the general requirements for their respective hazard classes contained in Subpart A. The Coast Guard proposes to require segregation of cargoes from

Page 34586

incompatible materials as shown in new Tables 148.120A and B. These tables present the requirements for, respectively, segregating incompatible bulk solid cargoes, and segregating bulk solid cargoes from incompatible packaged cargoes. The segregation requirements set out in Tables 148.120A and B are based on a rational approach established by the IMO, and are identical to the IMSBC Code. The Coast

Guard proposes additional stowage and segregation requirements, detailed by class, in the remainder of Subpart D. 5. Proposed Subpart E--Special Requirements for Certain Materials

Proposed Subpart E would set forth special requirements for certain hazardous materials, including ammonium nitrate, DRI, seed cake, and zinc ashes. For clarity, the requirements are presented in tabular form at new proposed Table 148.155. Many of the requirements are drawn from the IMSBC Code, or are required already under applicable special permits. The addition of Table 148.155 will reduce the number of special permits issued and harmonize these regulations with the IMSBC

Code.

In addition to listing special requirements for certain hazardous materials, this subpart proposes requirements for bulk shipment of hazardous substances as defined by PHMSA regulations at 49 CFR 171.8, which in turn are based on Environmental Protection Agency (EPA) regulations implementing the Comprehensive Environmental Response,

Compensation, and Liability Act (CERCLA). The EPA classifies materials as hazardous substances based on the material's potential to endanger public health or welfare, or the environment, if the material is accidentally released. Materials classified as hazardous substances under 49 CFR 172.101, Table 1 to Appendix A, previously were carried only pursuant to special permits on a case-by-case basis. This section would not relieve the shipper or the master from any of the reporting requirements set forth in 40 CFR part 302, but would set out minimum requirements for the safe carriage of solid hazardous substances in bulk.

Within Subpart E, the Coast Guard proposes to revise current Sec. 148.04-13 so that a vessel may not leave port unless the Captain of the

Port (COTP) is satisfied that the temperature of ferrous metal is within the limits set by the applicable provisions of this section. The current regulation merely specifies that the COTP must be notified if the temperature exceeds those limits.

In the specific context of petroleum coke, the Coast Guard proposes to combine two existing sections (Sec. Sec. 148.04-15 and 148.04-17) into one section at Sec. 148.295. The proposed requirements at new

Sec. 148.295 align with the IMSBC Code and already are required under applicable special permits.

With regard to radioactive materials, the Coast Guard proposes to revise the current Sec. 148.04-1 as Sec. 148.300 and align it with the IMSBC Code, which has re-defined low specific activity (LSA) radioactive materials and added a new entry for SCO-I. As a result, the proposed regulations would apply to surface contaminated objects.

In the specific context of seed cake, we have proposed to exempt from this regulation citrus pulp pellets containing not more than 2.5 percent oil and a maximum of 14 percent oil and moisture combined. Our decision was based on extensive testing at various moisture and oil levels from several countries currently transporting the product. It was found that within these limits, the product should not be considered a hazardous material.

Although the Coast Guard intends to harmonize U.S. regulations with the IMSBC Code, the proposed Sec. 148.330, which applies to zinc ashes, zinc dross, zinc residues, and zinc skimmings in bulk, would differ significantly from the IMSBC Code. As proposed, Sec. 148.330 requires COTP notification in advance of any cargo transfer operations involving these cargoes. The provisions of this section are based on two Coast Guard special permits, SP 8-83 and SP 4-84, which we developed as the result of incidents involving fires or explosions in cargoes of zinc skimmings, including at least one with loss of life.

The intent of this section would be to reduce the possibility of generating hydrogen gas through the reaction of seawater and zinc.

Therefore, the aging, storage, and temperature requirements in this proposed section exceed those in the IMSBC Code. Both the IMSBC Code and the proposed regulations require mechanical ventilation, explosion- proof fans, and installed thermocouples for temperature gauging in the cargo hold. 6. Proposed Subpart F--Additional Special Requirements

Proposed column 7 of Table 148.10, ``Special Requirements,'' refers readers to other sections containing additional requirements. Many of those sections are contained in proposed Subpart F, which would set forth requirements for safety equipment and procedures when handling certain cargoes. The types of special requirements that may apply to certain cargoes include: prohibition on sources of ignition including, in some cases, smoking or electrical circuits; a requirement that fire hoses be available at each hatch through which a covered material is being loaded; requirements for toxic gas and flammable gas analyzers and testing; stowage precautions; and special precautions for cargoes subject to liquefaction.

With regard to cargoes subject to liquefaction, the Coast Guard's proposed rule results from specific experience. On April 11, 1991, off the California coast, a foreign-flag vessel that had loaded a bulk solid material in a U.S. port developed a severe list when the cargo shifted. Fortunately, this vessel was able to return to port and off- load. The Coast Guard investigation determined that the cargo shifted because its moisture content exceeded the safe Transportable Moisture

Limit (TML). This condition caused the material to behave like a liquid. Because of this marine casualty and others of a similar nature, the Coast Guard proposes to add new Sec. 148.450 to prescribe requirements for transporting bulk solids that are subject to liquefaction. These proposed rules are adapted from the IMSBC Code and only apply to calcined pyrites, fluorospar, fine particle coal, metal sulfide concentrates, and peat moss, as indicated in Table 148.10, and to other cargoes that exhibit the potential for liquefaction as indicated by information provided to the master in accordance with 97.12-3. The proposed rules would not apply to shipments by unmanned barges or cargoes of coal that have an average particle size of 10 mm

(0.394 in) or greater. The moisture content and TML may be determined using test procedures in Appendix 2 of the IMSBC Code.
Distribution Table for Part 148

The Coast Guard proposes to replace existing Part 148 with a completely revised and renumbered Part 148. The following distribution table shows which sections of the proposed rule address the substance of each existing section.

VI. Incorporation by Reference

Material proposed for incorporation by reference appears in Sec. 148.8 of the proposed rule. You may inspect this material at U.S. Coast

Guard Headquarters where indicated under ADDRESSES. Copies of the material are available from the sources listed in Sec. 148.8.

Before publishing a binding rule, we will submit this material to the Director of the Federal Register for approval of the incorporation by reference.

VII. Regulatory Analyses

We developed this proposed rule after considering numerous statutes and executive orders related to rulemaking. Below we summarize our analysis based on 13 of these statutes or executive orders.
Regulatory Planning and Review

This proposed rule is not a significant regulatory action under section 3(f) of Executive Order 12866, Regulatory Planning and Review, and does not require an assessment of potential costs and benefits under section 6(a)(3) of that Order. The Office of Management and

Budget (OMB) has not reviewed it under that Order.

A combined ``Preliminary Regulatory Assessment and Initial

Regulatory Flexibility Analysis'' report discussing the impact of this proposed rule is available in the docket where indicated under

ADDRESSES. A summary of the report follows:

The Coast Guard proposes to harmonize its regulations with recent

IMO amendments to Chapter VI and Chapter VII of SOLAS that make the

IMSBC Code mandatory for operations involving handling and carriage of solid bulk cargoes by vessel. The amendments require that all vessels subject to SOLAS that carry bulk solid cargoes other than grain to comply with the IMSBC Code. This proposed rule also would amend the

Coast Guard regulations governing the carriage of solid hazardous materials in bulk to allow use of the IMSBC as an equivalent form of compliance. Proposed changes to the Coast Guard regulations would also expand the list of solid hazardous materials authorized for bulk transportation by vessel and include special handling procedures based on the IMSBC Code and existing special permits. These proposed changes would reduce the need for the current special permits required for the carriage of certain solid hazardous materials in bulk and result in a cost savings to industry.

The IMSBC Code facilitates safe stowage and shipment of solid bulk cargoes. It provides information on the dangers associated with shipping certain types of solid bulk cargoes and instructions on procedures for handling said cargoes. The IMSBC Code will be mandatory under the amendments to the SOLAS Convention as of January 1, 2011.

Affected Population

Based on information from the Coast Guard's Marine Information for

Safety and Law Enforcement (MISLE) data system, we estimate the proposed rule would affect approximately 115 vessels, consisting of 75

U.S. vessels in coastwise service and 40 U.S. vessels operating under

SOLAS that ship hazardous solid cargoes in bulk.

Costs

We estimate the proposed rule would result in additional equipment, training, and operating costs to industry. Under the provisions of this proposed rule, each vessel would be required to have onboard non- sparking fans, an oxygen meter, a carbon monoxide meter, a temperature probe, two SCBA, goggles and a dust mask, and a multi-gas detector. We estimate that industry would incur equipment costs during the implementation period (Year 1) of $2.7 million undiscounted. We also estimate there will be annual recurring costs due to equipment maintenance and replacement (see the Preliminary Regulatory Analysis report available in the docket for additional details).

The use of the equipment described above would require additional training. We estimate industry would incur initial training costs in the first year of $33,900 and annual recurring training costs due to labor turnover of about $6,800 each year thereafter (estimates undiscounted). Operating costs would consist of testing, recording keeping, and vessel preparation. The equipment described above would be used to periodically test the temperature and atmospheric conditions of certain cargoes. All tests and readings must be recorded, and the date and time of testing recorded in the vessel's log book. We estimate industry would incur an annual recurring operating cost of $7.4 million undiscounted.

Cost Savings

This proposed rule would also result in cost savings to certain vessels, as preparation of permit renewals will no longer be needed. We estimate this regulation would reduce the need for ten permit requests per year. Based on information provided in the OMB-approved Information

Collection Request (Carriage of Bulk Solid Materials Requiring Special

Handling: 1625-0025), annual cost savings for both industry and government are estimated at $15,390 undiscounted.

Table 1 below provides the net costs (adjusted for savings) of this proposed rule. We estimate the undiscounted first-year cost of the rulemaking to be about $10.1 million. Over a 10-year period, the total present value costs of the proposed rule would be $57.2 million at a 7 percent discount rate and $69.3 million at a 3 percent discount rate.

Benefits

In this rulemaking, the Coast Guard anticipates that benefits would include a reduction in the risks associated with off-gassing and self- heating cargoes. These proposed standards are comprehensive safety requirements that would align with international regulations (the IMSBC

Code), and are intended to increase information dissemination regarding the safe handling of hazardous cargoes.

These safety standards would extend to all U.S.-flagged vessels carrying hazardous bulk solid cargoes. A lack of safe handling of hazardous cargoes, such as coal or wood, can cause combustion of cargoes and the release of gases that could result in the loss of life, injuries, and property damage, among others. The proposed rule would also improve the efficiency of government by reducing the administrative costs associated with special permit applications.
Small Entities

Under the Regulatory Flexibility Act (5 U.S.C. 601-612), 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.

A combined ``Preliminary Regulatory Assessment and Initial

Regulatory Flexibility Analysis'' report discussing the impact of this proposed rule on small entities is available in the docket where indicated under the ``Public Participation and Request for Comments'' section of this preamble. A summary of this report follows:

For this proposed rule, we reviewed size and ownership data of affected entities by using the Coast Guard's MISLE database and public and proprietary data sources for company revenue and employee size data. We determined that 86 entities own the 115 vessels that would be impacted by this regulation. We found revenue and employment information on 33 of the 86 entities. We found that all affected entities would be businesses. Among these, eight would be considered small entities under the Small Business Administration (SBA) standard.

We take a conservative approach by assuming vessels listed as

``unspecified'' and those with no available information are small (of which there are 52). Therefore, we estimate that 70 percent of the entities meet the SBA standards of a small entity.

Using the highest single year cost (Year 1) in the Total 10-Year

Costs table above, we estimate that 75 percent of the small entities would have an annual cost impact of greater than or equal to 3 percent of annual revenue.

If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and that the proposed regulation will 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 proposed rule will economically affect it.
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 proposed rule so that they can better evaluate its effects on them and participate in the rule. If the proposed rule would affect your small business, organization, or governmental jurisdiction and you have questions concerning its provisions or options for compliance, please contact Richard Bornhorst at the telephone number or e-mail address indicated under the FOR

FURTHER INFORMATION CONTACT section of this notice. 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).
Collection of Information

This proposed rule would revise an existing collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501- 3520). As defined in 5 CFR 1320.3(c), ``collection of information'' comprises reporting, recordkeeping, monitoring, posting, labeling, and other similar actions. The title and description of the information collection, a description of those who must collect the information, and an estimate of the change in annual burden follow. The estimated change covers the time for preparing or renewing permit requests for hazardous solid bulk cargoes.

Under the conditions of the proposed rule, vessels and barge companies would no longer submit special permit renewal requests to the

U.S. Coast Guard. Handling requirements related to previously permitted cargoes would be part of 46 CFR part 148. Eliminating these permits would reduce the burden associated with 1625-0025 by reducing the number of respondents, responses, and burden hours associated with permits requests.

Title: Carriage of Bulk Solid Materials Requiring Special Handling.

Page 34589

OMB Control Number: 1625-0025.

Summary of the Collection of Information: The U.S. Coast Guard administers and enforces the law, regulations, and international conventions for the safe transportation and stowage of hazardous materials, including bulk solids. Consequently, the Coast Guard is authorized to issue special permits for the handling of hazardous solid bulk cargo as part of its missions to ensure maritime safety and facilitate U.S. commerce. In addition to special permits, this collection of information also authorizes the preparation and display of shipping papers and cargo manifests. However, the proposed rule will change only the burden estimates associated with special permits.

Need for Information: The Special Permits allow the Coast Guard to control the conditions under which shipments of hazardous materials can be made, while giving the shipping industry a greater amount of flexibility than would be afforded without the Special Permit provision. If the required information were not submitted, the Coast

Guard would be unable to issue Special Permits with adequate precautions for shipping the cargo, and thus could not permit shipment.

Proposed Use of Information: The Coast Guard uses this information to make a well-informed determination as to the severity of the hazard posed by the material in question. This information allows the Coast

Guard to set specific guidelines for safe carriage or, if determined that a material presents too great a hazard, to deny permission for shipping the material.

Description of the Respondents: The respondents are owners and operators of bulk carrier vessels and barges carrying hazardous solid cargo.

Number of Respondents: The existing OMB-approved number of respondents for this collection, including permit requests, shipping papers, and cargo manifest, is 583. We estimate the number of respondents will decrease by seven as the proposed rule eliminates the need for all but one special permit. The total number of respondents would be 576.

Number of Responses: The existing OMB-approved number of responses is 771. The proposed rule would decrease that number by 10. The total number of responses would be 761 per year as a result of a decrease in special permit requests.

Frequency of Response: The proposed regulation will not alter the frequency of response for permits that remain active. Since this regulation does not impact shipping papers or cargo manifests, frequency of responses for those items remain unchanged.

Burden of Response: The estimated burden for preparation of a permit request remains at 15 hours per permit.

Estimate of Total Annual Burden: This regulation will eliminate the need for all but one of the special permits associated with this collection of information. Therefore, the annual burden associated with special permits will decline from 165 hours to 15 hours. The total burden for the collection of information, including cargo manifests and shipping papers, decreases from 895 hours to 745 hours per year.

Reason for Change: The decrease in burden is the result of a program change that eliminates the need for most of the special permits in this collection of information.

As required by the Paperwork Reduction Act of 1995 (44 USC 3507(d)), we have submitted a copy of this proposed rule to the OMB for its review of the collection of information.

We ask for public comment on the proposed collection of information to help us determine how useful the information is; whether it can help us perform our functions better; whether it is readily available elsewhere; how accurate our estimate of the burden of collection is; how valid our methods for determining burden are; how we can improve the quality, usefulness, and clarity of the information; and how we can minimize the burden of collection.

If you submit comments on the collection of information, submit them both to OMB and to the Docket Management Facility where indicated under ADDRESSES, by the date under DATES.

You need not respond to a collection of information unless it displays a currently valid control number from OMB. Before the requirements for this collection of information become effective, we will publish a notice in the Federal Register of OMB's decision to approve, modify, or disapprove the collection.
Federalism

A rule has implications for federalism under Executive Order 13132,

Federalism, if it has a substantial direct effect on State or local governments and would either preempt state law or impose a substantial direct cost of compliance on them.

It is well settled that States may not regulate in categories reserved for regulation by the Coast Guard. It is also well settled, now, 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. (See the decision of the Supreme Court in the consolidated cases of United States v. Locke and Intertanko v. Locke, 529 U.S. 89

(Mar. 6, 2000)).

This proposed rule includes requirements under which certain solid materials requiring special handling may be transported in bulk by vessel. The revised regulations apply to all domestic and foreign vessels in the navigable waters of the United States that transport bulk solid materials requiring special handling. The authority to establish such regulations for vessels operating in the navigable waters of the United States has been committed to the Coast Guard by

Federal statutes. Furthermore, since vessels tend to move from port to port in the national and international marketplace, the safety standards included in this rule are of national scope to avoid burdensome variances. Therefore, the Coast Guard intends this rule to preempt state action addressing the same subject matter.

Because the states may not regulate within this category, preemption considerations set forth in Executive Order 13132 are not applicable.
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 1 year. Though this proposed rule would not result in such an expenditure, we do discuss the effects of this rule elsewhere in this preamble.
Taking of Private Property

This proposed rule would not cause a taking of private property or otherwise have taking implications under Executive Order 12630,

Government Actions and Interference with Constitutionally Protected

Property Rights.
Civil Justice Reform

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

Page 34590

eliminate ambiguity, and reduce burden.

I. Protection of Children

We have analyzed this proposed rule under Executive Order 13045,

Protection of Children from Environmental Health Risks and Safety

Risks. This rule is not an economically significant rule and would not create an environmental risk to health or risk to safety that might disproportionately affect children.
Indian Tribal Governments

This proposed rule does not have tribal implications under

Executive Order 13175, Consultation and Coordination with Indian Tribal

Governments, because it would 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.
Energy Effects

We have analyzed this proposed 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. 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 Executive Order 13211.

L. Technical Standards

The National Technology Transfer and Advancement Act (NTTAA) (15

U.S.C. 272 note) directs agencies to use voluntary consensus standards in their regulatory activities unless the agency provides Congress, through the Office of Management and Budget, 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 incorporates by reference the IMSBC Code, which was developed by the IMO as a voluntary consensus standard. The proposed sections that reference this voluntary consensus standard and the locations where this standard is available are listed in the proposed 46 CFR 148.8.
Environment

We have analyzed this proposed rule under Department of Homeland

Security 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. Therefore, this rule is categorically excluded under section 2.B.2. Figure 2-1, paragraphs 34(c), (d), and

(e), of the Instruction, and neither an environmental assessment nor an environmental impact statement is required. This rule affects crew training, inspection and equipping of vessels, equipment approval and carriage requirements. A preliminary ``Environmental Analysis Check

List'' supporting this determination is available in the docket where indicated under the ``Public Participation and Request for Comments'' section of this preamble. We seek any comments or information that may lead to the discovery of a significant environmental impact from this proposed rule.

Subpart A--General

Sec. 148.1 Purpose and applicability.

(
1. This part prescribes special handling procedures for certain solid materials that present hazards when transported in bulk by vessel.
(b) Except as noted in paragraph (c) of this section, this part applies to all domestic and foreign vessels in the navigable waters of the U.S that transport bulk solid materials requiring special handling.

(c) This part does not apply to an unmanned barge on a domestic voyage carrying a Potentially Dangerous Material (PDM) found in Table 148.10 of this part. All barges on international voyages must follow the requirements for PDM.

(d) The regulations in this part have preemptive impact over State law on the same subject. The Coast Guard has determined, after considering the factors developed by the Supreme Court in U.S. v.

Locke, 529 U.S. 89 (2000), that in directing the Secretary to regulate the safe transportation of hazardous material and the safety of individuals and property on board vessels subject to inspection, as well as the provision of loading information, Congress intended to preempt the field of safety standards for solid materials requiring special handling when transported in bulk on vessels.

Sec. 148.2 Responsibility and compliance.

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

Sec. 148.3 Definitions.

As used in this part--

A-60 class division means a division as defined in Sec. 32.57-5 of this chapter.

Adjacent space means any enclosed space on a vessel, such as a cargo hold, cargo compartment, accommodation space, working space, storeroom, passageway, or tunnel, that shares a common bulkhead or deck with a hatch, door, scuttle, cable fitting or other penetration, with a cargo hold or compartment containing a material listed in Table 148.10 of this part.

Away from means a horizontal separation of at least 3 meters (10 feet) projected vertically is maintained between incompatible materials carried in the same hold or on deck.

Bulk applies to any solid material, consisting of a combination of particles, granules, or any larger pieces of material generally uniform in composition, that is loaded directly into the cargo spaces of a vessel without any intermediate form of containment.

Bulk Cargo Shipping Name or BCSN identifies a bulk solid material during transport by sea. When a cargo is listed in this Part, the BCSN of the cargo is identified by Roman type and is listed in Column 1 of

Table 148.10 of this part. When the cargo is a hazardous material, as defined in 49 CFR part 173, the proper shipping name of that material is the BCSN.

Cold-molded briquettes are briquettes of direct reduced iron (DRI) that have been molded at a temperature of under 650 [deg]C (1202

deg
or that have a density of under 5.0 g/cm[sup3].

Hazardous Material.

Hazardous substance is a hazardous substance as defined in 49 CFR 171.8.

Hold means a compartment below deck that is used exclusively for the stowage of cargo.

Hot-molded briquettes are briquettes of DRI that have been molded at a temperature of 650 [deg]C (1202 [deg]F) or higher, and that have a density of 5.0 g/cm\3\ (312 lb/ft\3\) or greater.

IMSBC Code means the English version of the ``International

Maritime Solid Bulk Cargoes Code'' published by the International

Maritime Organization (incorporated by reference, see Sec. 148.8).

Incompatible materials means two materials whose stowage together may result in undue hazards in the case of leakage, spillage, or other accident.

International voyage means voyages--

(1) Between any place in the United States and any place in a foreign country;

(2) Between places in the United States through a foreign country; or

(3) Between places in one or more foreign countries through the

United States.

Lower flammability limit or LFL means the lowest concentration of a material or gas that will propagate a flame. The LFL is usually expressed as a percent by volume of a material or gas in air.

Master means the officer having command of a vessel. The functions assigned to the master in this part may also be performed by a representative of the master or by a person in charge of a barge.

Material safety data sheet or MSDS is as defined in 29 CFR 1910.1200.

Person in charge of a barge means an individual designated by the owner or operator of a barge to have charge of the barge.

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

Bulk (MHB).

Readily combustible material means a material that may not be a hazardous material but that can easily ignite and support combustion.

Examples are wood, straw, vegetable fibers, and products made from these materials, and coal lubricants and oils. The term does not include packaging material or dunnage.

Reportable quantity or RQ means the quantity of a hazardous substance spilled or released that requires a report to the National

Response Center. The specific RQs for each hazardous substance are available in 49 CFR 172.101, Appendix A.

Responsible person means a knowledgeable person who the master of a vessel or owner or operator of a barge makes responsible for all decisions relating to his or her specific task.

Seed cake means the residue remaining after vegetable oil has been extracted by a solvent or mechanical process from oil-bearing seeds, such as coconuts, cotton seed, peanuts, and linseed.

Shipper means any person by whom, or in whose name, or on whose behalf, a contract of carriage of goods by sea has been concluded with a carrier; or any person by whom or in whose name, or on whose behalf, the goods are actually delivered to the carrier in relation to the contract of carriage by sea.

Shipping paper means a shipping order, bill of lading, manifest, or other shipping document serving a similar purpose.

Stowage factor means the volume in cubic meters of 1,000 kilograms

(0.984 long tons) of a bulk solid material.

Threshold limit value or TLV means the time-weighted average concentration of a material that the average worker can be exposed to over a normal eight-hour working day, day after day, without adverse effect. This is a trademark term of the American Conference of

Governmental Industrial Hygienists (ACGIH).

Transported includes the various operations associated with cargo transportation, such as loading, off-loading, handling, stowing, carrying, and conveying.

Trimming means any leveling of a cargo within a cargo hold or compartment, either partial or total.

Tripartite agreement means an agreement between the national administrations of the port of loading, the port of discharge, and the flag state of the vessel, on the conditions of carriage of a cargo.

Page 34593

Ventilation means exchange of air from outside to inside a cargo space and includes the following types:

(1) Continuous ventilation means ventilation that is operating at all times. Continuous ventilation may be either natural or mechanical;

(2) Mechanical ventilation means power-generated ventilation;

(3) Natural ventilation means ventilation that is not power- generated; and

(4) Surface ventilation means ventilation of the space above the cargo. Surface ventilation may be either natural or mechanical.

Vessel means a cargo ship or barge.

Sec. 148.5 Alternative procedures.

(
1. The Commandant (CG-5223) may authorize the use of an alternative procedure, including exemptions to the IMSBC Code
  
  (incorporated by reference, see Sec. 148.8), in place of any requirement of this part if it is demonstrated to the satisfaction of the Coast Guard that the requirement is impracticable or unnecessary and that an equivalent level of safety can be maintained.
  
  (b) Each request for authorization of an alternative procedure must--
  
  (1) Be in writing;
  
  (2) Name the requirement for which the alternative is requested; and
  
  (3) Contain a detailed explanation of--
  
  (i) Why the requirement is impractical or unnecessary; and
  
  (ii) How an equivalent level of safety will be maintained.

3. A material listed in Table 148.10 of this section may be transported as a bulk solid cargo on a vessel if it is carried according to this part. A material that is not listed in Table 148.10 of this section, but which is hazardous or a potentially dangerous material (PDM), requires a Special Permit under Sec. 148.15 to be transported on the navigable waters of the United States.
  
  (b) For each listed material, Table 148.10 identifies the hazard class and gives the BCSN or directs the user to the preferred BCSN. In addition, the table lists specific hazardous or potentially dangerous characteristics associated with each material and specifies or references detailed special requirements in this part pertaining to the stowage or transport of specific bulk solid materials. The column descriptions for Table 148.10 are defined as follows:
  
  (1) Column 1: Bulk Solid Material Descriptions and Bulk Cargo
  
  Shipping Names (BCSN). Column 1 lists the bulk solid material descriptions and the BCSNs of materials designated as hazardous or PDM.
  
  BCSNs are limited to those shown in Roman type. Trade names and additional descriptive text are shown in italics.
  
  (2) Column 2: I.D. Number. Column 2 lists the identification number assigned to each BCSN associated with a hazardous material. Those preceded by the letters ``UN'' are associated with BCSNs considered appropriate for international voyages as well as domestic voyages.
  
  Those preceded by the letters ``NA'' are associated with BCSNs not recognized for international voyages, except to and from Canada.
  
  (3) Column 3: Hazard Class or Division. Column 3 designates the hazard class or division, or PDM, as appropriate, corresponding to each
  
  BCSN.
  
  (4) Column 4: References. Column 4 refers the user to the preferred
  
  BCSN corresponding to bulk solid material descriptions listed in Column 1.
  
  (5) Column 5: Hazardous or Potentially Dangerous Characteristics.
  
  Column 5 specifies codes for hazardous or potentially dangerous characteristics applicable to specific hazardous materials or PDMs.
  
  Refer to Sec. 148.11 for the meaning of each code.
  
  (6) Column 6: Other Characteristics. Column 6 contains other pertinent characteristics applicable to specific bulk solid materials listed in Column 1.
  
  (7) Column 7: Special Requirements. Column 7 specifies the applicable sections of Part 148 of this chapter that contain detailed special requirements pertaining to stowage and/or transportation of specific bulk solid materials in this part. This column is completed in a manner which indicates that ``Sec. 148.'' precedes the designated numerical entry.

  (2) Any specific requirements in Subpart D of this part.
  
  (b) Materials that are required to be separated during stowage must not be handled at the same time. Any residue from a material must be removed before a material required to be separated from it is loaded.
  
  (c) Definitions and application of segregation terms:
  
  (1) ``Separated from'' means located in different cargo compartments or holds when stowed under deck. If the intervening deck is resistant to fire and
  
  Page 34600
  
  liquid, a vertical separation, i.e., in different cargo compartments, is acceptable as equivalent to this segregation.
  
  (2) ``Separated by a complete cargo compartment or hold from'' means either a vertical or horizontal separation, for example, by a complete cargo compartment or hold. If the intervening decks are not resistant to fire and liquid, only horizontal separation is acceptable.
  
  (3) ``Separated longitudinally by an intervening complete cargo compartment or hold from'' means that vertical separation alone does not meet this requirement.
