SUPPLEMENTARY INFORMATION:

I. Background

    This final rule reduces regulatory burdens on industry by 
incorporating changes into the Hazardous Materials Regulations (HMR) 
based on PHMSA's own initiatives and petitions for rulemaking submitted 
in accordance with 49 CFR 106.95. In a continuing effort to review the 
HMR for necessary revisions, PHMSA (``we'' and ``us'') is eliminating, 
revising, clarifying and relaxing certain other regulatory 
requirements. On August 12, 2004, RSPA, the predecessor agency to 
PHMSA, published a notice of proposed rulemaking (NPRM) under Docket 
RSPA-04-18683 (HM-218C; 69 FR 49846). The NPRM contained information 
concerning each proposal and invited public comment. Readers should 
refer to the NPRM for additional background discussion. We received 
eight comments in response to the NPRM. These comments were submitted 
by trade associations, such as the Air Transport Association (ATA), the 
Chlorine Institute (CI), and the International Vessel Operators 
Hazardous Materials Association, Inc. (VOHMA); hazardous materials 
consulting firms; and providers of emergency response. Most commenters 
expressed support for various proposals, but some commenters raised 
concerns about certain provisions in the proposal that are discussed 
below. Certain commenters raised issues that are beyond the scope of 
this rulemaking; such comments will not be addressed.
    The following is a section-by-section summary of changes, and, 
where applicable, a discussion of comments received.

Section-by-Section Review

Part 171
Section 171.7
    In the NPRM, we proposed to incorporate by reference a document 
entitled ``An Example of a Test Method for Vent Sizing--OPPSD/SPI 
Methodology,'' which described an alternative method to determine the 
vent size of emergency relief devices on portable tanks transporting 
organic peroxides. This document was added to the Sec.  171.7(b) List 
of informational materials not requiring incorporation by reference in 
a final rule published December 20, 2004, under Docket No. RSPA-04-
17036 (HM-215G; 69 FR 76061); therefore, the proposal is not adopted in 
this final rule.
    Under the entry ``American Society for Testing and Materials'' 
(ASTM), we are incorporating by reference ASTM Standards A 1008/A 
1008M-03 ``Standard Specification for Steel, Sheet, Cold-Rolled, 
Carbon, Structural, High-Strength Low-Alloy and High-Strength Low-Alloy 
with Improved Formability'' and A 1011/A 1011M-03a ``Standard 
Specification for Steel, Sheet and Strip, Hot-Rolled, Carbon, 
Structural, High-Strength Low-Alloy and High-Strength Low-Alloy with 
Improved Formability.'' We received a comment from the ASTM requesting 
we incorporate by reference ASTM Standards A1008/A1008M-04b and A1011/
A1011M-04a to reflect the latest version of these standards. Because we 
did not propose to incorporate the newer edition of these standards in 
the NPRM, we are not incorporating them at this time. These standards 
may be considered for incorporation by reference in a future 
rulemaking.
    We are updating the Compressed Gas Association ``CGA Pamphlet C-
6.1, Standards for Visual Inspection of High Pressure Aluminum 
Compressed Gas Cylinders'' from the 1995 edition to the 2002 edition. 
We proposed to update CGA Pamphlet C-6.1 in an NPRM published on 
September 10, 2003, under Docket No. RSPA-03-14405 (HM-220F; 68 FR 
53318). Because of delay in finalizing HM-220F, we are incorporating 
the 2002 edition of CGA Pamphlet C-6.1 in this final rule. The 2002 
edition of the standard has provisions discussing cleaning methods that 
may result in the removal of cylinder wall material. It also contains a 
new requirement that all aluminum cylinders be internally inspected for 
cracks in the neck region. Also see Sec.  180.212 preamble discussion.
    We are incorporating by reference the Department of Defense's (DOD) 
``Packaging of Hazardous Material, DLAD 4145.41/AR 700-143/AFJI 24-210/
NAVSUPINST 4030.55B/MCO 4030.40B.''
    Also, we are updating the following documents which are 
incorporated by reference:

--Chlorine Institute instruction booklets entitled ``Chlorine Institute 
Emergency Kit `A' for 100-lb. & 150-lb. Chlorine Cylinders'' (Edition 
10, June 2003) and ``Chlorine Institute Emergency Kit `B' for Chlorine 
Ton Containers'' (Edition 9, June 2003);
--Transport Canada ``Transportation of Dangerous Goods Regulations 
(August 15, 2001)'' edition.

    In paragraph (b), we are removing the table entry ``National 
Association of Corrosive Engineers (NACE)'' and NACE Standard TM-01-69 
which described an acceptable test for a liquid corrosive material. 
This entry is obsolete because the definition and testing methods for 
corrosive materials have been revised.
Section 171.8
    In the NPRM, we proposed to revise the definition for ``Materials 
of trade'' (MOTS) by removing the phrase ``in direct support of a 
principal business that is other than transportation by motor 
vehicle.'' This would allow private carriage of qualified hazardous 
materials under the MOTs exception regardless of the principal business 
of the carrier. We received one comment in favor of this proposal. 
Since publication of the NPRM, we have identified additional issues 
pertaining to the transportation of hazardous materials under the MOTs 
exception that require further study; therefore, we are not adopting 
the proposal in this final rule.
Section 171.12a
    In paragraph (b)(2), we are clarifying that certain exceptions in 
Transport Canada's Transportation of Dangerous Goods (TDG) Regulations 
are not

[[Page 34067]]

recognized under the reciprocity provisions; specifically, materials 
subject to the 500 kg exception in paragraph 1.16 of the TDG 
Regulations may not be transported under the provisions of Sec.  
171.12a and are subject to the requirements of the HMR.
Section 171.14
    We are removing paragraph (d)(3) because the transition period for 
use of the KEEP AWAY FROM FOOD label and placard has expired.
Part 172
Section 172.101
    We are adding a statement in Sec.  172.101(i)(3) and a new 
paragraph (i)(5) to clarify that some bulk packaging authorizations are 
found in column (8B) and the special provisions in column (7) of the 
HMT.
    We are revising the entry for ``Bromine'' and adding two new 
entries, one for bromine solution, PIH Zone A and one for bromine 
solution, PIH Zone B. This recognizes that some bromine solutions do 
not meet the criteria for a PIH Zone A material and are, in fact, in 
Hazard Zone B. Also, for the entry ``Bromine'' we are adding stowage 
category ``D'' for vessel transportation in column (10A) of the HMT. In 
the NPRM, we proposed to remove Special provisions A3 and A6 in column 
(7) for the entry ``Bromine.'' Special provisions A3 and A6 were 
removed in a final rule published December 20, 2004, under Docket No. 
RSPA-04-17036 (HM-215G; 69 FR 76075).
    We are reinstating the entry ``Denatured Alcohol, NA 1987'' in 
response to a petition by the Renewable Fuels Association (P-1430). We 
are also adding a new Special provision 172 for the entries ``Denatured 
Alcohol, NA 1987'' and ``Alcohols, n.o.s., UN 1987'' to allow solutions 
of alcohol and petroleum products to be described as either ``Denatured 
Alcohol'' or ``Alcohols, n.o.s.'' provided the solution contains no 
more than 5% petroleum products.
    For the entries ``sec-Butyl chloroformate, NA 2742'' and ``Isobutyl 
chloroformate, NA 2742'' we are adding the word ``Forbidden'' in 
columns (9A) and (9B). These materials are poisonous by inhalation in 
Hazard Zone B and are forbidden on passenger and cargo only aircraft.
    For the entry ``Refrigerating machines, containing flammable, non-
toxic, liquefied gas, UN 3358'' we are adding a reference to Sec.  
173.307 in column (8A) of the HMT. This will except refrigerating 
machines containing 12 kg (25 pounds) or less of a flammable, non-toxic 
gas from the HMR, except when offered or transported by air or vessel. 
We are also correcting inconsistencies with the International Maritime 
Dangerous Goods (IMDG) Code pertaining to vessel stowage for this 
entry.
    In the NPRM, we proposed to add a reference to the limited quantity 
exception for flammable liquids in Column (8A) of the HMT for the entry 
``1,3,5-Trimethylbenzene, UN 2325.'' We revised the entry ``1,3,5-
Trimethylbenzene, UN 2325'' in a final rule published December 20, 
2004, under Docket No. RSPA-04-17036 (HM-215G; 69 FR 76145) to include 
the limited quantity exception.
Section 172.102
    We are revising Special provision 53 to provide relief from the 
subsidiary hazard class/division entry on the shipping paper if the 
material is excepted from the subsidiary label requirements. We are 
also adding a new Special provision 172 for alcohol mixtures containing 
up to 5% petroleum products.
Section 172.203
    We are adding a new paragraph (l)(4) that cross-references the 
requirements and exceptions for marine pollutants in Sec.  171.4. A 
commenter suggests that the language proposed in the NPRM might suggest 
``the consignor who packs the freight container or other cargo 
transport unit and offers it in intermodal transportation has no 
obligation to declare the marine pollutant on the shipping paper, or 
mark the inner packages and the CTU with the MARINE POLLUTANT mark 
since the initial transport is by road or rail.'' The commenter asks us 
to exclude shipments that are ``intended for vessel transportation'' 
from the exception in Sec.  171.4. We disagree. Marine pollutants in 
non-bulk packagings transported domestically by rail or motor vehicle 
are not subject to the HMR. If subsequent transportation is by vessel, 
the shipment must be brought into compliance. The HMR do not prescribe 
how this is to be accomplished; it is left to the shippers' discretion. 
Mandating compliance with the vessel transportation requirements of the 
HMR or the IMDG Code from the original point of origin may impose 
additional burdens and costs to the offeror. We did not consider such 
burdens and associated costs and consider this comment beyond the scope 
of this rulemaking. We disagree with the commenter that the proposed 
language creates difficulties for the shipper; it is a cross-reference 
to existing language in Sec.  171.4 and does not impose additional 
burdens. We are adopting the paragraph as proposed.
Section 172.205
    We are adding a new paragraph (i) alerting the user that the word 
``Waste'' must precede the proper shipping name as provided by Sec.  
172.101(c)(9).
Section 172.504
    We are amending Sec.  172.504(g)(2) to clarify that explosives 
articles of compatibility groups C, D, or E when transported with 
explosives articles in compatibility group N may be placarded with a 
Class 1 compatibility group D placard. The display of only one placard 
bearing one compatibility letter when certain Class 1 materials of 
different compatibility groups are transported together in a single 
transport vehicle or container is authorized in the HMR.
Section 172.519
    We are editorially revising paragraph (f) by adding the 
parenthetical phrase ``(IBR, see Sec.  171.7 of this subchapter),'' 
after the wording ``ICAO Technical Instructions, the IMDG Code, or the 
TDG Regulations.''
Part 173
Section 173.7
    We are authorizing military shipments of hazardous materials to be 
packaged in accordance with the procedures prescribed in the DOD 
document ``Packaging of Hazardous Material, DLAD 4145.41/AR 700-143/
AFJI 24-210/NAVSUPINST 4030.55B/MCO 4030.40B'' as an alternative to the 
HMR. This document replaces the packaging standards in the document 
``Performance Oriented Packagings of Hazardous Material, DLAR 4145.41/
AR 700-143/AFR 71-5/NAVSUPINST 4030.55/MCO 4030.40.''
Section 173.28
    In paragraph (b)(3), we are clarifying that packagings made of 
fiberboard are authorized for reuse.
Section 173.31
    We are amending paragraph (b) to except tank cars transporting 
elevated temperature materials and molten sulfur from retrofit bottom 
discontinuity protection requirements. Based on past risk-analysis 
evaluations conducted by the Federal Railroad Administration (FRA) and 
industry, it was determined that tank cars transporting elevated 
temperature materials and molten sulfur do not require retrofit 
protection.
Section 173.150
    In the NPRM, we proposed to remove paragraph (f)(1), which contains 
the

[[Page 34068]]

definition of ``combustible liquid.'' The definition is also found in 
Sec.  173.120 Class 3--Definitions. VOHMA requested we reconsider this 
proposal because of problems that are encountered in intermodal 
transportation. Combustible liquids in non-bulk packagings are not 
subject to the HMR when transported domestically. VOHMA states that 
when these shipments are subsequently offered for international 
transportation, re-shippers may be unaware that these materials are 
regulated in international commerce and may fail to comply with the 
applicable regulations. VOHMA suggests that retaining the 
classification criteria for a combustible liquid in Sec.  173.150 may 
alert shippers to the classification differences between the HMR and 
international regulations and prevent undeclared hazardous materials 
from entering the transportation system. We agree, and are not adopting 
this proposal.
Section 173.225
    In the NPRM, we proposed to revise the Note to paragraph (e)(3)(vi) 
by authorizing an alternative method to determine the size of 
emergency-relief devices on portable tanks. In a final rule published 
on December 20, 2004, under Docket No. RSPA 04-17036 (HM-215G; 69 FR 
76172), we redesignated paragraph (e) as paragraph (h) and authorized 
this alternative method of an emergency-relief device sizing.
Section 173.241
    For clarity, in paragraph (c), we are adding a reference to certain 
additional requirements in Sec.  176.340 that apply when offering 
combustible liquids in portable tanks for transportation by vessel.
Section 173.301
    In the NPRM, we proposed to revise the requirement in paragraph 
(a)(9) that a strong outer packaging containing specification 2P, 2Q, 
3E, 3HT, spherical 4BA, 4D, 4DA, 4DS, and 39 cylinders must conform to 
the requirements in Sec.  173.25. Instead of referencing Sec.  173.25, 
we proposed to require the outside of the combination packaging to be 
marked with an indication that the inner packagings conform to the 
prescribed specification. Our intention was to clarify that the outer 
packaging is not an overpack and, thus, each inner cylinder must comply 
with the Part 172 marking and labeling requirements. The Air Transport 
Association (ATA) objects to marking the outer packaging with a 
statement indicating that the inner packagings conform to the 
prescribed specifications because it implies ``that the outer 
packagings are in fact overpacks and would create inconsistency with 
the International Civil Aviation Organization's Technical Instructions, 
where, beginning in 2005, an overpack must be marked with the word 
`Overpack.' '' ATA also requests that we delete the reference to an 
overpack in Special provision A52. ATA states that air carriers use 
many thin walled DOT 3HT cylinders that are required to be placed in 
outer packagings meeting the ATA specification 300 standard and meet 
the strong outer packaging requirement in Sec.  173.302a(a)(2) of the 
HMR. ATA states that, should the proposed marking be finalized, air 
carriers will be forced to use separate marked packagings for their DOT 
3HT cylinders. Also, ATA suggests that operational confusion regarding 
the appropriate use or reuse of outer packagings marked with the 
proposed marking instead of the ``Overpack'' marking could lead to 
unwarranted actions by enforcement personnel.
    We disagree with ATA that a marking indicating the inner packagings 
conforming to the prescribed specification implies the packaging is an 
overpack. There are other instances in the HMR where this marking is 
required, e.g., in Sec.  173.306 where DOT 2P and 2Q containers must be 
in a combination packaging and the outer packaging is a non-
specification packaging. Because the outer packaging does not have 
specification markings, the proposed marking alerts anyone coming into 
contact with the package that the inner container is a specification 
packaging.
    We also disagree with ATA that Special provision A52 should be 
revised to remove the word ``overpack.'' The special provision requires 
an oxygen cylinder that is loaded into a passenger-carrying aircraft or 
into an inaccessible cargo location on a cargo-only aircraft to be 
placed in an overpack or an outer packaging meeting the performance 
criteria in ATA specification 300 for Category I. The current HMR 
requirements authorize compressed oxygen to be packaged in DOT 3, 3A, 
3AA, 3AL, 3B, 3E, 3HT, 4B, 4BA and 4BW cylinders. Of these cylinders, 
only the DOT 3E, 3HT and spherical 4BA cylinders are considered to be 
inner packagings. The other cylinders must be properly marked and 
labeled individually in accordance with Part 172 and, when offered for 
air transportation, placed in an overpack conforming to Sec.  173.25.
    In this final rule, we are revising paragraph (a)(9) to require an 
outer packaging containing specification 2P, 2Q, 3E, 3HT, spherical 
4BA, 4D, 4DA, 4DS, and 39 cylinders to be marked to indicate that the 
inner packagings conform to the prescribed specifications, as proposed 
in the NPRM. Consistent with this change, we are also revising the last 
sentence in Sec.  173.302a(a)(2) and Note 7 following the table in 
Sec.  173.304a(a)(2) by adding a reference to Sec.  173.301(a)(9).
    In paragraph (l)(2), we are revising the wording to state clearly 
that foreign cylinders filled for export, in addition to meeting the 
maximum filling density and service pressure requirements, must be 
fitted with pressure relief devices when required by the HMR for the 
gas contained within the cylinder.
    We are editorially revising paragraph (m) by adding the 
parenthetical phrase ``(IBR, see Sec.  171.7 of this subchapter)'' 
after the first occurrence of the term ``Canadian Transport of 
Dangerous Goods (TDG) Regulations.''
Section 173.302a
    In paragraph (a)(2), we are removing the reference to the overpack 
provisions in Sec.  173.25 and adding a reference to Sec.  
173.301(a)(9).
    We are editorially revising paragraph (a)(3).
    In paragraph (d), we are authorizing use of a DOT 3AL1800 cylinder 
for the transportation of diborane and diborane mixtures.
    We are adding new paragraph (e) to reinstate the requirement that a 
cylinder containing fluorine may not be charged to over 400 psig at 21 
[deg]C (70 [deg]F) and may not contain more than 2.7 kg (6 lbs) of gas.
Section 173.304a
    In the paragraph (a)(2) table, in column 3, we are removing several 
references to DOT specification 4, 4A, 9, 38, 40 and 41 cylinders that 
are no longer authorized for use. Also, for the entry 
Bromotrifluoromethane, in column 3, we are correcting the reference 
``DOT-3AL40'' to read ``DOT-3AL400.'' We are revising the last sentence 
in Note 7 following the table to reference the packaging provisions in 
Sec.  173.301(a)(9). We are also correcting a typographical error in 
Note 8.
Sections 173.314 and 173.319
    In the NPRM, we proposed to require notification of delayed rail 
cars containing a time-sensitive product to the FRA instead of the 
Bureau of Explosives (BOE). Two commenters, the Chlorine Institute and 
the BOE, support moving the reporting requirements to FRA. The Chlorine 
Institute also states that the carrier, not the shipper, should be 
reporting the delay since the carrier knows where the rail car is. In 
the NPRM, we did not propose to transfer

[[Page 34069]]

this requirement from the shipper to the carrier. At this time, we 
prefer to retain the reporting requirement as a shipper responsibility 
and are adopting the change as proposed.
    We also received a comment from the AAR regarding our statement in 
the Regulatory Analyses and Notices section of this rule that ``BOE no 
longer exists.'' We apologize for this misstatement. Since 1997 the 
Bureau of Explosives Field Force and associated activities have been 
under the direction of The Transportation Technology Center, Inc., 
which is a wholly owned subsidiary of the AAR.
Section 173.315
    In the paragraph (a) table, column 4, we are adding a reference to 
Note 27 for the entry ``Ammonia, anhydrous or Ammonia solutions, with 
greater than 50 percent ammonia,'' and following the table, we are 
adding a new Note 27 to authorize the use of non-specification cargo 
tanks.
Section 173.337
    In the introductory text, we are reinstating a requirement that a 
cylinder containing nitric oxide may be charged to a pressure of not 
more than 5,170 kPa (750 psig) at 21[deg] C (70[deg] F).
Part 178
Sections 178.338-2 and 178.345-2
    We are removing the reference to ASTM Standard A 607 and adding 
ASTM Standards A 1008/A 1008M and A 1011/A 1011M in its place.
Section 178.606
    In paragraph (c)(2), we are correcting the formula for calculating 
the pressure to be applied when a packaging containing a solid is 
subjected to a dynamic compression test.
Part 179
Section 179.200-7
    In paragraph (e), we are adding a reference to Sec.  171.7 for a 
standard that is incorporated by reference.
Part 180
Section 180.205
    In paragraph (c)(2), we are adding a reference to new Sec.  
180.212. See Sec.  180.212 preamble discussion. Also, we are broadening 
the provisions in paragraph (i)(2) to allow a composite cylinder that 
is condemned to have the wording ``CONDEMNED'' displayed instead of 
stamped on the cylinder. The use of a label is currently authorized in 
some exemptions.
Section 180.212
    We are adding a new section allowing repairs to a DOT 3-series 
cylinder under the terms of an approval issued by the Associate 
Administrator under Subpart I of Part 107. In addition, the person who 
performs the repair work must have an approval as currently required 
under Subpart H of Part 107. An approval will not be required for the 
removal and replacement of non-pressure components on a DOT 3-series 
cylinder, such as a neck ring or foot ring; the replacement material 
must be equivalent to that used at the time of original manufacture.
    Additionally, in the NPRM, we proposed that an approval would not 
be required for the repair of worn or damaged cylinder neck threads 
when performed by the original cylinder manufacturer in accordance with 
the cylinder's specification requirements and under the supervision of 
an independent inspection agency. We are relaxing this provision to 
permit re-threading to be performed by any manufacturer of these types 
of cylinders. CGA Pamphlets C-6 and C-6.1 contain guidelines for 
inspection of the cylinder neck areas for damaged threads. The cylinder 
must be rejected if the required number of effective threads are not 
engaged to provide a gas-tight seal. The rejected cylinder may qualify 
for repair to restore the effectiveness of the threads. If the threads 
cannot be repaired, the cylinder must be condemned. We proposed to 
update the reference to CGA Pamphlet C-6.1 from the 1995 to the 2002 
edition in an NPRM published on September 10, 2003 (HM-220F; 68 FR 
53318). The 2002 edition contains criteria for inspection of cylinder 
neck threads for abnormal thread conditions resulting from structural 
defects, corrosion, or damage. Because of delay in finalizing HM-220F, 
we are incorporating the 2002 edition of CGA Pamphlet C-6.1 in this 
final rule. Currently CGA is updating CGA Pamphlet C-6 to better 
address inspection for neck areas on high pressure and low pressure 
steel cylinders. We will consider adopting the revised pamphlet in a 
future rulemaking.
Section 180.417
    In paragraph (b)(2)(v), we are reinstating the requirement that 
each test or inspection report completed for a repaired cargo tank must 
include the ASME or National Board Certificate of Authorization number 
of the facility performing the repairs.

Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking
    This final rule is published under authority of Federal hazardous 
materials transportation law (Federal hazmat law; 49 U.S.C. 5101 et 
seq.) Section 5103(b) of Federal hazmat law authorizes the Secretary of 
Transportation to prescribe regulations for the safe transportation, 
including security, of hazardous materials in intrastate, interstate, 
and foreign commere.
B. Executive Order 12866 and DOT Regulatory Policies and Procedures
    This final rule is not considered a significant regulatory action 
under section 3(f) and was not reviewed by the Office of Management and 
Budget (OMB). This final rule is not considered a significant rule 
under the Regulatory Policies and Procedures of the U.S. Department of 
Transportation (44 FR 11034). The costs and benefits of this rule are 
considered to be so minimal as to not warrant preparation of a 
regulatory evaluation.
    In this final rule, we are amending miscellaneous provisions in the 
HMR to clarify the provisions and to relax overly burdensome 
requirements. We are also responding to requests from industry 
associations to update and add references to standards that are 
incorporated in the HMR. These clarifications and updates of the HMR 
will enhance safety while reducing the compliance burden on the 
regulated industry. In the NPRM, we invited public comment on any 
impacts of the proposed changes. We did not receive any comments 
regarding the impacts of these changes.
C. Executive Order 13132
    This final rule was analyzed in accordance with the principles and 
criteria contained in Executive Order 13132 (``Federalism''). This 
final rule preempts state, local and Indian tribe requirements but does 
not impose any regulation that has substantial direct effects on the 
States, the relationship between the national government and the 
States, or the distribution of power and responsibilities among the 
various levels of government. Therefore, the consultation and funding 
requirements of Executive Order 13132 do not apply.
    Federal hazardous material transportation law, 49 U.S.C. 
5125(b)(1), contains an express preemption provision (49 U.S.C. 
5125(b)) preempting State, local, and Indian tribe requirements on 
certain covered subjects:

[[Page 34070]]

    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous material and requirements related to the number, 
content, and placement of those documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; or
    (5) The design, manufacture, fabrication, marking, maintenance, 
reconditioning, repair, or testing of a packaging or container which is 
represented, marked, certified, or sold as qualified for use in the 
transport of hazardous material.
    This final rule addresses covered subject items (1), (2), and (5) 
described above and preempts any State, local, or Indian tribe 
requirements concerning these subjects unless the non-Federal 
requirements are ``substantively the same'' (see 49 CFR 107.202(d)) as 
the Federal requirements.
    Federal hazardous materials transportation law provides at 49 
U.S.C. 5125(b)(2) that if PHMSA issues a regulation concerning any of 
the covered subjects, PHMSA must determine and publish in the Federal 
Register the effective date of Federal preemption. That effective date 
may not be earlier than the 90th day following the date of issuance of 
the final rule and not later than two years after the date of issuance. 
The effective date of preemption of this final rule is 90 days from 
publication of this final rule in the Federal Register.
D. Executive Order 13175
    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 13175 (``Consultation and 
Coordination with Indian Tribal Governments''). Because this final rule 
does not have tribal implications and does not impose substantial 
direct compliance costs, the funding and consultation requirements of 
Executive Order 13175 do not apply.
E. Regulatory Flexibility Act, Executive Order 13272, and DOT 
Procedures and Policies
    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
agency to review regulations to assess their impact on small entities. 
An agency must conduct a regulatory flexibility analysis unless it 
determines and certifies that a rule is not expected to have a 
significant impact on a substantial number of small entities. This 
final rule amends miscellaneous provisions in the HMR to clarify 
provisions based on our own initiatives and also on petitions for 
rulemaking. While maintaining safety, it relaxes certain requirements 
that are overly burdensome and updates references to consensus 
standards that are incorporated in the HMR. These amendments are 
intended to provide relief to shippers, carriers, and packaging 
manufacturers, including small entities.
    This final rule has been developed in accordance with Executive 
Order 13272 (``Proper Consideration of Small Entities in Agency 
Rulemaking'') and DOT's procedures and policies to promote compliance 
with the Regulatory Flexibility Act to ensure that potential impacts of 
draft rules on small entities are properly considered. The changes 
proposed in this Notice will enhance safety while reducing the 
compliance burden on the regulated industry. I certify that this final 
rule does not have a significant economic impact on a substantial 
number of small entities.
F. Paperwork Reduction Act
    PHMSA currently has an approved information collection under OMB 
Control Number 2137-0559, ``Requirements for Rail Tank Car Tanks--
Transportation of Hazardous Materials by Rail'' with 2,759 burden 
hours, and an expiration date of May 31, 2006. This final rule will 
result in a minimal increase in information collection and 
recordkeeping burden under OMB Control Number 2137-0559, due to 
editorial changes to Sec. Sec.  173.314 and 173.319. We are removing 
references to BOE in Sec. Sec.  173.314 and 173.319, and replacing them 
with references to FRA. Therefore, this final rule will result in a 
minimal increase in burden since FRA instead of BOE will now be 
notified if a rail car containing a time-sensitive product is not 
received within 20 days from shipment.
    Section 1320.8(d), Title 5, Code of Federal Regulations requires 
that PHMSA provide interested members of the public and affected 
agencies an opportunity to comment on information collection and 
recordkeeping requests. This final rule identifies a revised 
information collection request that PHMSA will submit to OMB for 
approval based on the requirements in this final rule.
    PHMSA has developed burden estimates to reflect changes in this 
final rule. The revised burden indicated below includes revisions in 
this final rule and corrections of previous mathematical errors 
discovered during the review process. PHMSA estimates the net total of 
information and recordkeeping burden in this final rule as: 
``Requirements for Rail Tank Car Tanks--Transportation of Hazardous 
Materials by Rail'' OMB Number 2137-0559:
    Total Annual Number of Respondents: 266.
    Total Annual Responses: 16,781.
    Total Annual Burden Hours: 2,689.
    Total Annual Burden Cost: $102,586.25.
    Requests for a copy of this information collection should be 
directed to Deborah Boothe or T. Glenn Foster, Office of Hazardous 
Materials Standards (PHH-11), Pipeline and Hazardous Materials Safety 
Administration, Room 8430, 400 Seventh Street, SW., Washington, DC 
20590-0001, Telephone (202) 366-8553. We will publish a notice advising 
interested parties of the OMB approval for this information collection 
request when approved by OMB.
    In addition, you may submit comments specifically related to the 
information collection burden to the PHMSA Desk Officer, OMB, at fax 
number 202-395-6974. Under the Paperwork Reduction Act of 1995, no 
person is required to respond to an information collection unless it 
displays a valid OMB control number.
G. 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.
H. Unfunded Mandates Reform Act
    This final rule does not impose unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. It does not result in costs of 
$120.7 million or more to either state, local, or tribal governments, 
in the aggregate, or to the private sector, and is the least burdensome 
alternative that achieves the objectives of the rule.
I. Environmental Assessment
    The National Environmental Policy Act of 1969 (NEPA), as amended 
(42 U.S.C. 4321-4347) requires Federal agencies to consider the 
consequences of major Federal actions and prepare a detailed statement 
on actions significantly affecting the quality of the human 
environment. We developed an assessment to determine the effects of 
this final rule on the environment and have concluded that there would 
be no

[[Page 34071]]

significant environmental impacts associated with this final rule.
J. Privacy Act
    Anyone is able to search the electronic form of any written 
communications and comments received into any of our dockets by the 
name of the individual submitting the document (or signing the 
document, if submitted on behalf of an association, business, labor 
union, etc.). You may review DOT's complete Privacy Act Statement in 
the Federal Register published on April 11, 2000 (65 FR 19477) or you

    (a) General requirements for repair of DOT 3 series cylinders. (1) 
No person may repair a DOT 3-series cylinder unless--
    (i) The repair facility holds an approval issued under the 
provisions of subpart I of part 107 of subchapter A of this chapter; 
and
    (ii) Except as provided in paragraph (b) of this section, the 
repair and the inspection are performed under the provisions of an 
approval issued under subpart H of part 107 of subchapter A of this 
chapter and conform to the applicable cylinder specification contained 
in Part 178 of this subchapter.
    (2) The person performing the repair must prepare a report 
containing, at a minimum, the results prescribed in Sec.  180.215.
    (b) Repairs not requiring prior approval. Approval is not required 
for the following specific repairs:
    (1) The removal and replacement of a neck ring or foot ring on a 
DOT 3A, 3AA, or 3B cylinder that does not affect a pressure part of the 
cylinder when the repair is performed by a repair facility or a 
cylinder manufacturer of these types of cylinders. The repair may be 
made by welding or brazing in conformance with the original 
specification. After removal and before replacement, the cylinder must 
be visually inspected and any defective cylinder must be rejected. The 
heat treatment, testing and inspection of the repair must be performed 
under the supervision of an inspector and in accordance with the 
original specification.
    (2) External re-threading of a DOT 3AX, 3AAX or 3T cylinder or 
internal re-threading of a DOT-3 series cylinder to restore the total 
number of neck threads engaged to the condition specified in the 
applicable specification. The repair work must be performed by a 
manufacturer of these types of cylinders. Upon completion of the re-
threading, the threaded opening must be inspected by an independent 
inspection agency and gauged in accordance with Federal Standard H-28 
or an equivalent standard containing the same specification limits. The 
re-threaded cylinder must be stamped clearly and legibly with the word 
``RETHREAD'' on the shoulder, head, or neck. No cylinder may be re-
threaded more than one time without approval of the Associate 
Administrator.
