Intermediate Bulk Containers for Hazardous Materials

AGENCY: Research and Special Programs Administration (RSPA), DOT.

ACTION: Final rule; revisions and response to petitions for 
reconsideration.

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

SUMMARY: This amendment makes revisions to a final rule published in 
the Federal Register under Docket HM-181E (59 FR 38040, July 26, 1994) 
in response to a number of petitions for reconsideration. This document 
also clarifies and makes corrections to the final rule. That final rule 
established requirements for the construction, maintenance and use of 
intermediate bulk containers (IBCs) for the transportation of hazardous 
materials. These changes respond to petitions for reconsideration 
regarding IBC authorizations, design, construction and use, and align 
requirements for IBCs with revisions in the 8th edition of the U.N. 
Recommendations on the Transport of Dangerous Goods and the 27th 
revision of the International Maritime Organization's International 
Maritime Dangerous Goods (IMDG) Code.

DATES: This amendment is effective on October 1, 1995. However, 
immediate compliance with the regulations as amended herein is 
authorized.
    Incorporation by reference: The incorporation by reference listed 
in this final rule is approved by the Director of the Office of the 
Federal Register as of October 1, 1995.

FOR FURTHER INFORMATION CONTACT: John Potter, Office of Hazardous 
Materials Standards, (202) 366-8553 or William Gramer, Office of 
Hazardous Materials Technology, (202) 366-4545, RSPA, U.S. Department 
of Transportation, 400 Seventh Street SW., Washington DC 20590-0001.

SUPPLEMENTARY INFORMATION: On July 26, 1994, the Research and Special 
Programs Administration published a final rule under Docket HM-181E (59 
FR 38040) that revised the Hazardous Materials Regulations (HMR; 49 CFR 
Parts 171-180) by incorporating requirements for the construction, 
maintenance and use of IBCs for the transportation of hazardous 
materials. In response to 29 petitions for reconsideration, this 
document revises, clarifies and makes corrections to the final rule. 
Petitioners recommended revisions to: (1) The policy stated in the 
preamble at 59 FR 38040 addressing exemption packagings affected by 
this final rule; (2) the special provisions for IBCs contained in 
Sec. 172.102; (3) the provision for the manufacture and use of DOT 
specification 56 and 57 portable tanks provided in Sec. 173.32(d); (4) 
operational requirements for reuse of IBCs in Sec. 173.35(b); (5) 
generic authorizations for use of IBCs in Secs. 173.240, 173.241, 
173.242, and 173.243; (6) standards for rigid plastic and composite 
IBCs in Secs. 178.706 and 178.707; (7) responsibility for the 
performance of UN-certified IBCs in Sec. 178.801(b); (8) testing and 
certification of IBCs in Sec. 178.803; and (9) application of the IBC 
vibration test in Sec. 178.819.
    Several petitions relating to IBC commodity authorizations, such as 
hydrogen peroxide aqueous solutions, were addressed in a final rule 
published under Docket HM-215A (59 FR 67390-67522, December 29, 1994).

Petitions Granted

    In response to petitions, authorizations for use of IBCs for a 
number of materials are added to the Sec. 172.101 Hazardous Materials 
Table. Some of these changes are consistent with many of the latest 
revised IBC authorizations in the International Maritime Organization's 
International Maritime Dangerous Goods (IMDG) Code. Others reflect 
prior safe hazardous materials shipping experience in DOT exemption 
bulk packagings. For example, IBC authorizations are revised for a 
number of Division 4.3 DANGEROUS WHEN WET materials in Packing Groups 
II and III, which were previously forbidden for transportation in IBCs. 
Many of these materials now are permitted in all sift-proof and water-
resistant IBCs. In addition, certain Division 4.3 Packing Group I solid 
materials are authorized for transportation in IBCs, consistent with 
the IMDG Code. Prohibitions against use of IBCs are removed from 
``Cyclohexylamine'' and ``Hafnium powder, dry.'' A wider range of IBCs 
is permitted for ``Toxic, liquids, organic, n.o.s.,'' and ``Toxic 
liquid, inorganic, n.o.s.,'' Packing Group II.
    One petitioner asked RSPA to add filling limit provisions to the 
IBC operational requirements in Sec. 173.35 similar to those provided 
in Sec. 173.24a(b) for non-bulk packagings. For example, the gross mass 
(or net mass in the case of flexible IBCs) marked on the IBC can be 
exceeded when the IBC is tested and certified for a Packing Group II 
liquid and filled with a Packing Group III solid; or an IBC is tested 
and certified for a Packing Group I solid and filled with a Packing 
Group II or Packing Group III solid. RSPA concurs and, accordingly, is 
adding a paragraph (l) to provide for this flexibility in IBC use. RSPA 
notes that the amount by which the gross mass of IBCs can be exceeded 
in these cases is based on the ratios between drop heights specified 
for Packing Groups I and III (2.25) and Packing Groups I and II, and II 
and III (1.5). IBCs certified for liquids may also be used for solids.
    In response to a petition, a maximum net mass capacity standard of 
not less than 400 kilograms (882 pounds) is added in Sec. 178.700(c)(1) 
for consistency with similar standards for non-bulk packagings in 
subpart L. To reduce the need for IBC retesting, RSPA grants a petition 
from the Rigid Intermediate Bulk Container Association by adding Note 6 
to the table of IBC tests in Sec. 178.803 to permit any desired 
sequencing of the vibration test for dual-marked, exemption IBCs and 
non-DOT specification portable tanks intended for export that were 
tested before October 1, 1994.
    Several petitioners requested removal of the word ``rotate'' from 
the vibration test method prescribed for IBCs in Sec. 178.819(b)(2). 
They contend that allowing an IBC to rotate would involve a ``major 
redesign of all known testing platforms and restraining members.'' 
Section 178.608(b)(2) requires that non-bulk packagings be left free to 
rotate, a standard that may be inappropriate for IBCs which are 
unlikely to experience the same vibration stresses in transportation. 
RSPA further acknowledges that the vibration test requirement for DOT 
56 and 57 portable tanks in Secs. 178.252-3 and 178.253-5 allows only 
vertical motion. Therefore, the word ``rotate'' is removed from the 
test method stated in Sec. 178.819(b)(2). However, RSPA will not 
restrict rotation if it is included in an established vibration test 
protocol.
    One petitioner stated that general requirements in Sec. 178.801(b) 
for assuring that each IBC is capable of meeting Part 178 performance 
standards are inconsistent with other provisions in the HMR. As 
written, the petitioner said, paragraph (b) makes the shipper 
``responsible for every aspect of [IBC] fabrication and testing, 
including those aspects that were not performed by the shipper.'' The 
petitioner suggested that paragraph (b) conform with final rules 
published under HM-215A clarifying Secs. 173.22, 178.2 and 178.601(b) 

[[Page 40031]]
requiring shippers to be responsible for only the manufacturing 
functions they perform. RSPA concurs and paragraph (b) is revised 
accordingly.
Petitions Denied

    A petitioner claimed that RSPA's exemption policy for IBCs 
established in the final rule (59 FR 38040) is unworkable for every 
exemption IBC considered to be ``equivalent'' to IBCs already meeting 
UN standards. The petitioner said no exemption IBC could meet terms in 
option 2 permitting exemption IBCs to be certified as UN standard 
packagings if they already conform with subpart N and O requirements. 
The petitioner said, ``A builder of existing exemption tanks would have 
had to predict the tests and their order in testing that DOT 
prescribes.'' The petitioner observed that the proposed testing 
differed from tests prescribed in the final rule. The petitioner asked 
RSPA to add a note to the table of IBC tests in Sec. 178.803 allowing 
exemption IBCs to be marked to indicate compliance with subparts N and 
O but that they need not ``be tested as prescribed in this section.'' 
However, the petitioner said such IBCs ``must be capable of passing all 
the applicable tests.''
    This request is denied. Exemption IBCs that meet new construction 
and performance testing standards in subparts N and O, under option 2, 
``may be remarked and certified as UN standard packagings.'' Under 
option 3, existing exemption IBCs developed under standards different 
from those adopted under subparts N and O ``may be approved as a UN 
standard packaging'' under the approval process provided in 
Sec. 178.801(i) if they are shown to be equally effective and testing 
methods used are equivalent to UN standards. With respect to the 
petitioner's request, under option 3, manufacturers or users of IBCs 
differing from subpart O requirements in the way they were tested, 
including test sequences differing from the order of tests established 
in Sec. 178.803, may demonstrate that IBCs developed under exemption 
are equally effective, including test methods.
    Several petitioners requested indefinite use of exemption IBCs as 
long as they meet applicable periodic retest requirements. These 
requests are denied. Under the exemption policy stated at 59 FR 38040, 
an equivalent packaging may be approved by RSPA as a UN standard 
packaging under the provision in Sec. 178.801(i).
    A petitioner's request to revise Sec. 173.35(b) to permit reuse of 
flexible IBCs is denied. As RSPA pointed out in the preamble to the 
final rule in HM-181E (59 FR 38042), there is a lack of sufficient 
evidence ``that fiberboard, wooden or flexible IBCs are designed to be, 
or are suitable for, reuse in hazardous materials service.''
    Two petitioners asked RSPA to amend paragraph (c) of Secs. 173.240 
and 173.241 by adding the phrase ``rigid intermediate bulk containers 
`` to the titles of these paragraphs. They requested revisions to 
Sec. 173.240(c) to authorize ``sift-proof non-DOT specification 
portable tanks, closed bulk bins and rigid intermediate bulk containers 
suitable for transport of liquids,'' and to Sec. 173.241(c) to 
authorize ``non-DOT specification portable tanks and intermediate bulk 
containers suitable for transport of liquids.'' The petitions are 
denied since a non-specification bulk packaging fitting this 
description currently is permitted by paragraph (c) of these sections. 
In effect, any rigid enclosed packaging that is strong and tight (but 
not a flexible IBC), and constructed so that its contents will not leak 
under conditions normally incident to transportation meets requirements 
for a ``closed bulk bin'' in Sec. 173.240(c), a ``sift-proof non-DOT 
specification portable tank'' in Sec. 173.240(c), or a ``non-DOT 
specification portable tank suitable for transport of liquids'' in 
Sec. 173.241(c).
    Petitioners asked RSPA to authorize, under Sec. 173.242, rigid 
plastic and composite IBCs for ``Oxidizing substances, liquid, 
corrosive, n.o.s.,'' Packing Group II, and ``Corrosive liquids, 
oxidizing, n.o.s.,'' Packing Group II. In the final rule, these 
materials are authorized in metal-only IBCs under Sec. 173.243. The 
petitions are denied. RSPA believes there is an insufficient shipment 
history of these materials in a wide range of IBC design types to 
warrant broader IBC authorization.
    RSPA is denying a petition to restore DOT 56 and 57 portable tank 
design and construction requirements in Secs. 178.251 through 178.251-
7, 178.252 and 178.253. The petitioner claimed that removal of these 
sections would lead to ``unnecessary confusion and uncertainty'' since 
new construction of these tanks is authorized through September 30, 
1996. Removal of construction requirements for DOT Specification 56 and 
57 portable tanks is consistent with removal of pre-HM-181 non-bulk 
packaging specifications four years prior to the date on which they 
were no longer permitted to be manufactured. For reference to DOT 56 
and 57 specifications, manufacturers and users can retain the 1993 
edition of 49 CFR Parts 100-199, as amended. However, RSPA encourages 
them to convert to the new standards as soon as practicable. A 
petitioner asked RSPA to add a ``fusible'' device to the pressure 
relief devices specified for metal, rigid plastic and composite IBCs in 
Secs. 178.705(c)(2)(i), 178.706(c)(4) and 178.707(c)(3)(iv). This 
petition is denied as unnecessary. Fusible devices are currently 
permitted by the provision in each section that states pressure relief 
may be achieved by ``other means of construction.''
    Petitions requesting revisions to Secs. 178.706(c)(3) and 
178.707(c)(3)(iii) to permit use of recycled materials for the 
construction of plastic and composite IBCs are denied. Although RSPA 
recognizes the benefits of recycling plastic waste, RSPA has not been 
provided with sufficient information to justify use of recycled plastic 
materials in the construction of IBCs.
    Petitions to allow use of the ``USA'' mark on IBCs manufactured in 
other countries and intended for sale and use in the U.S. are denied. 
As clarified in Sec. 178.3(b)(3) under Docket HM-215A (59 FR 67519, 
December 29, 1994), ``the letters `USA' may only be used to indicate 
that the IBC was manufactured in the United States.'' IBCs manufactured 
in a foreign country should conform to requirements of the competent 
authority of that country.
Clarifications and Corrections

    In other revisions to this final rule, RSPA corrects U.S. standard 
conversions relating to the upper capacity for IBCs authorized for 
Packing Group I solids in Sec. 173.242(d)(2)(i) to read ``53 cubic 
feet'' and ``106 cubic feet,'' respectively. Also in 
Sec. 173.242(d)(2), ``flexible'' and ``fiberboard'' IBCs (inadvertently 
omitted in the final rule) are authorized. In Sec. 173.243(d)(2)(i), 
Packing Group I solids are authorized for transportation in metal IBCs 
with capacities up to three cubic meters (106 cubic feet). In 
Sec. 178.700(c)(1)(i), the volumetric capacity for the body of a 
receptacle is specified as not more than three cubic meters (3,000 
liters, 793 gallons, or 106 cubic feet) and not less than 0.45 meters 
(450 liters, 119 gallons, or 15.9 cubic feet).
    RSPA is correcting Sec. 173.243(d)(2) by removing references to 
IBCs other than metal. Section 178.705(c)(2)(ii) is clarified to show 
that the pressure relief requirement for metal IBCs is measured in 
gauge pressure and not absolute pressure. Thus, reference to the 
subtraction of atmospheric pressure is removed and reference to 
measurement of gauge pressure of the hazardous 

[[Page 40032]]
material measured in the IBC is added in its place.
    RSPA is aligning the table of IBC tests in Sec. 178.803 with new 
provisions in the 8th revision of the UN Recommendations on the 
Transport of Dangerous Goods for the bottom lift and stacking tests. 
Therefore, in this final rule, rigid plastic and composite IBCs are 
required to be bottom lift-tested without qualification. References to 
Note 2 in the table specifying that test only if IBCs are ``designed to 
be handled'' this way are removed from rigid plastic and composite IBC 
design types. RSPA also is changing Note 2 to require metal IBCs to 
withstand either the top lift test or the bottom lift test. Note 7 is 
added to except metal, rigid plastic, composite, fiberboard and wooden 
IBCs from the stacking test if the IBC is not designed to be stacked.
    In this final rule, RSPA also is making an editorial correction to 
Sec. 173.306(e) by updating a reference to a national consensus 
standard for refrigerating machines. Section 173.306(e) is amended to 
replace the reference to ANSI B9.1 with a reference to ANSI/ASHRAE 15-
1994, which has superseded ANSI B9.1.

Regulatory Analyses and Notices

Executive Order 12866 and DOT Regulatory Policies and Procedures

    This final rule is not considered a significant regulatory action 
under section 3(f) of Executive Order 12866 and was not reviewed by the 
Office of Management and Budget. The rule is not considered significant 
under the Regulatory Policies and Procedures of the Department of 
Transportation (44 FR 11034).

Executive Order 12612

    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 12612 (``Federalism''). 
Federal law expressly preempts State, local, and Indian tribe 
requirements applicable to the transportation of hazardous materials 
that cover certain subjects and are not substantively the same as 
Federal requirements. 49 U.S.C. 5125(b)(1). Covered subjects are:
    (i) The designation, description, and classification of hazardous 
materials;
    (ii) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous materials;
    (iii) The preparation, execution, and use of shipping documents 
pertaining to hazardous materials and requirements respecting the 
number, content, and placement of such documents;
    (iv) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous materials; or
    (v) The design, manufacturing, fabrication, marking, maintenance, 
reconditioning, repairing, or testing of a package or container which 
is represented, marked, certified, or sold as qualified for use in the 
transportation of hazardous materials.
    This final rule addresses covered subjects, under items (ii) and 
(v) above and, therefore, preempts State, local, or Indian tribe 
requirements not meeting the ``substantively the same'' standard. The 
Federal hazardous materials transportation law (49 U.S.C. 5125(b)(2)) 
provides that if DOT issues a regulation concerning any of the covered 
subjects after November 16, 1990, DOT must determine and publish in the 
Federal Register the effective date of Federal preemption. The 
effective date may not be earlier than the 90th day following the date 
of issuance of the final rule and no later than two years after the 
date of issuance. RSPA has determined that the effective date of 
Federal preemption of the July 26, 1994 final rule was January 13, 
1995. RSPA has determined that the effective date of Federal preemption 
for this final rule will be November 1, 1995. Because RSPA lacks 
discretion in this area, preparation of a federalism assessment is not 
warranted.

Regulatory Flexibility Act

    I certify that this final rule will not have a significant economic 
impact on a substantial number of small entities. Although this rule 
applies to certain shippers and carriers of hazardous materials in 
intermediate bulk containers, some of whom may be small entities, its 
economic impacts are minimal.

Paperwork Reduction Act

    The information collection requirements contained in this rule have 
been approved by the Office of Management and Budget under the 
provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3504(h)) 
and assigned control number 2137-0510.

Regulation Identifier Number (RIN)

    A regulation identifier number (RIN) is assigned to each regulatory 
action listed in the Unified Agenda of Federal Regulations. The 
Regulatory Information Service Center publishes the Unified Agenda in 
April and October of each year. The RIN number contained in the heading 
of this document can be used to cross-reference this action with the 
Unified Agenda.
