Hazardous Materials: Miscellaneous Amendments (RRR)

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA), 
DOT.

ACTION: Notice of Proposed Rulemaking (NPRM).

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

SUMMARY: PHMSA proposes to make miscellaneous amendments to the 
Hazardous Materials Regulations to update and clarify certain 
regulatory requirements. These proposed amendments are designed to 
promote safer transportation practices, address petitions for 
rulemaking, respond to National Transportation Safety Board (NTSB) 
Safety Recommendations, facilitate international commerce, make 
editorial corrections, and simplify the regulations. The proposed 
provisions in this rulemaking include, but are not limited to, removing 
the packing group (PG) II designation for certain organic peroxides, 
self-reactive substances and explosives, incorporating requirements for 
trailers of manifolded acetylene cylinders, and providing requirements 
to allow for shipments of damaged wet electric batteries. In addition, 
this rulemaking proposes to revise the requirements for the packaging 
of nitric acid, testing of pressure relief devices on cargo tanks, and 
shipments of black or smokeless powder for small arms.

I. Background

    The purpose of this NPRM is to update and clarify the Hazardous 
Materials Regulations (HMR; 49 CFR parts 171-180) based on PHMSA's own 
initiatives. The proposed changes were identified through an extensive 
review of the HMR and letters of interpretation issued to the public. 
In addition, this NPRM proposes regulatory requirements that respond to 
seven petitions for rulemaking and addresses two NTSB Safety 
Recommendations. To this end, PHMSA is proposing to revise, clarify, 
and ease certain regulatory requirements.

II. Incorporation by Reference Discussion Under 1 CFR Part 51

    The American Association of Railroads (AAR) Manual of Standards and 
Recommended Practices, Section C-III, Specifications for Tank Cars, 
Specification M-1002 and the Compressed Gas Association (CGA) pamphlet 
G-1.6, Standard for Mobile Acetylene Trailer Systems, Seventh Edition 
(G-1.6, 2011) are available for interested parties to purchase in 
either print or electronic versions through the parent organization Web 
sites. The price charged for these standards to interested parties 
helps to cover the cost of developing, maintaining, hosting, and 
accessing these standards. The specific standards are discussed in 
greater detail in the following analysis.

III. Petitions for Rulemaking and National Transportation Safety Board 
Recommendations

A. Amendments to the HMR for Organic Peroxides, Self-Reactive 
Substances and Explosives (P-1590)

    In P-1590, DGAC requests that PHMSA amend the HMR by removing the 
PG II designation in Column (5) of the Sec.  172.101 HMT for all 
organic peroxides (Division 5.2), self-reactive substances (Division 
4.1), and explosives (Class 1). DGAC states that under both the HMR and 
international regulations, organic peroxides, self-reactive substances 
and explosives are not assigned a packing group. Despite the absence of 
regulatory language for determining a packing group assignment for 
these materials, proper shipping names for these materials listed in 
the HMT are assigned a default PG II. DGAC asserts that the presence of 
a PG assignment for these entries is a constant source of confusion 
which leads to frustration of shipments. DGAC further indicates that 
frustration typically occurs when shipping papers are inspected by 
carrier staff and enforcement personnel along the transport chain with 
respect to the Sec.  172.202(a)(4) requirement to include the ``packing 
group in Roman numerals, as designated for the hazardous material in 
Column (5) of the Sec.  172.101 table.''
    DGAC notes that while Sec.  172.202(a)(4) also excepts organic 
peroxides, self-reactive substances and explosives from the requirement 
to provide a PG as part of the required description, a great deal of 
confusion is created given that, irrespective of this exception, PGs 
are provided for these materials in the Sec.  172.101 HMT. DGAC also 
states that the HMR are inconsistent with international regulations as 
a PG is not indicated for these materials in the hazardous materials 
tables in the ICAO TI, IMDG Code, and the UN Model Regulations. In 
addition, those regulations restrict the provision of a PG in the 
transport document basic description to materials where a PG has been 
assigned in accordance with classification requirements. With no PG 
indicated for these substances in the respective lists, it is 
inappropriate to provide a PG in the hazardous materials description on 
a shipping paper under international regulations. Consequently, 
provision of a PG for domestic transportation would constitute a 
violation of international regulations for international 
transportation.
    DGAC states that removing the PG for these materials from the HMT 
would impose no additional costs and would result in a net savings 
since many unnecessary delays in hazardous material shipments would be 
avoided. DGAC did not provide a specific figure for the anticipated net 
savings.
    DGAC also states that the packaging provisions in Part 173 for 
these materials indicate the level of performance required. Therefore, 
although certain packagings must meet PG II performance levels, they do 
not indicate a degree of danger or the variation to PG I or PG III 
packagings.
    In response to DGAC's petition, PHMSA agreed that it merited a 
rulemaking change. We recognize that when the PG does not relate to the 
degree of hazard of the material based on classification criteria but 
rather is broadly assigned to an entire group of materials for purposes 
of applying regulatory requirements, there is limited value in 
requiring an indication of the PG on a shipping paper. Therefore PHMSA 
is proposing to remove the PG II designation from Column (5) of the HMT 
for organic peroxides (Division 5.2), self-reactive substances 
(Division 4.1), and explosives (Class 1). PHMSA seeks comment on the 
safety implications of such a change as well as the net benefit such a 
change (i.e., decrease in the number of frustrated shipments) would 
provide.

B. Marking Requirements for Poison by Inhalation Materials (P-1591)

    In P-1591, Air Products and Chemicals, Inc., requests that PHMSA 
amend the marking requirements for poison inhalation hazard (PIH) 
materials that are shipped in accordance with the IMDG Code or TDG 
Regulations. Specifically, the petitioner requests that PHMSA modify 
Sec. Sec.  171.23(b)(10)(iv)(A) and 171.23(b)(10)(iv)(B) to remove the 
phrase ``regardless of the total quantity contained in the transport 
vehicle or freight container'' in both paragraphs to align Part 171, 
Subpart C requirements for use of international regulations with the 
poisonous hazardous material marking requirements in Sec.  172.313(c), 
which offers exceptions based on Hazard Zone, quantity, and number of 
distinct materials.
    Specifically, subpart C of Part 171 specifies requirements for 
shipments offered for transportation or transported in the United 
States under international regulations. For PIH material, subparagraphs 
(A) and (B) of Sec.  171.23(b)(10)(iv) require that ``the transport 
vehicle or freight container must be marked with the identification 
numbers for the hazardous material, regardless of the total quantity 
contained in the transport vehicle or freight container, in the manner 
specified in Sec.  172.313(c) of this subchapter and placarded as 
required by subpart F of part 172 of this subchapter.'' The petitioner 
states that the phrase ``regardless of the total quantity contained in 
the transport vehicle or freight container'' gives the appearance that 
the identification number marking requirement is applicable to any 
quantity. However, the remainder of the sentence states that the 
marking must be ``in the manner specified in in Sec.  172.313(c) of 
this subchapter,'' which indicates an entirely different requirement.
    Section 172.313(c) specifies marking requirements for non-bulk 
packages of PIH material contained in transport vehicles or freight 
containers subject to certain provisions and limitations. Section Sec.  
172.313(c)(2) states, ``the transport vehicle or freight container is 
loaded at one facility with 1,000 kg (2,205 pounds) or more aggregate 
gross weight of the material in non-bulk packages marked with the same 
proper shipping name and identification number'' meaning that unless 
this criteria is met, marking the identification number on the 
transport vehicle or freight container is not required. The petitioner 
indicates the inconsistency of Sec. Sec.  171.23(b)(10)(iv)(A), 
171.23(b)(10)(iv)(B) and 172.313(c) is a source of confusion.
    The petitioner also identifies a potential discrepancy when 
transporting internationally to or from the United States in accordance 
with Sec.  171.23. The requirement to mark all quantities of PIH 
material is more restrictive and costly than the current marking 
requirements for the same materials when transported domestically under 
the HMR in accordance with Sec.  172.313(c). The petitioner points out 
that under both the IMDG and TDG there are no additional marking 
requirements for transport units carrying PIH materials in non-bulk 
packages similar to the provisions found in Sec.  172.313(c). 
Therefore, for quantities of PIH materials in non-bulk packages (less 
than 1,000 kg per UN number) all three regulations are not aligned.
    The petitioner states they have had numerous shipments of PIH 
materials frustrated because of this confusing requirement, and that 
the additional marking causes economic hardship and transit delays due 
to additional labor necessary to apply the extra UN identification 
numbers at the port. The petitioner did not provide a specific cost 
figure for these frustrated shipments or anticipated net savings of a 
regulatory change.
    In response to Air Products' petition, PHMSA agreed that it merited 
a rulemaking change. The intent of the requirements in Sec.  
171.23(b)(10)(iv) is to provide hazard communication for international 
shipments of PIH materials transiting the United States under either 
the IMDG Code or TDG equivalent to those established in the HMR, not to 
impose more restrictive requirements. The removal of the phrase 
referring to a ``total quantity'' will reduce potential confusion due 
to differences in inspection interpretations and will reduce handling 
costs and transit time while maintaining an acceptable level of hazard 
communication for PIH materials. Therefore, PHMSA is proposing to amend 
Sec. Sec.  171.23(b)(10)(iv)(A) and 171.23(b)(10)(iv)(B) by removing 
the phrase ``regardless of the total quantity contained in the 
transport vehicle or freight container'' from each subparagraph. PHMSA 
seeks comment on the safety implications of such a change as well as 
the net benefit such a change (i.e., decrease in the number of 
frustrated shipments) would provide.

C. Emergency Response Telephone Number (P-1597)

    In P-1597, DGAC requests that PHMSA amend the emergency response 
telephone number requirements to prohibit the use of alphanumeric 
telephone numbers and only permit numeric telephone numbers. Currently, 
the HMR do not limit the telephone numbers to be numeric under Sec.  
172.604(a). DGAC states that historically telephone faces associated 
integers with letters (e.g., 2\ABC\), but this is no longer the case in 
all instances of phones. As a result, emergency response telephone 
numbers presented alphanumerically could cause delays in acquiring 
emergency response information as the first responder would have to 
first convert letters to numbers. These delays are undesirable in time 
sensitive emergency response situations.
    DGAC further points out that PHMSA issued a letter of 
interpretation (Ref. No. 04-0032) confirming that alphanumeric 
presentation of an emergency response telephone number was acceptable 
but expressed concern in the delays it may cause.
    In response to DGAC's petition, PHMSA agreed that it merited a 
rulemaking change. We agree that the continued use of alphanumeric 
telephone numbers could cause unnecessary delays in emergency response 
situations, therefore, PHMSA is proposing to revise Sec.  172.604(a) to 
require a numeric format for the presentation of emergency response 
telephone numbers in association with a shipping paper. Additionally, 
we request specific comment on the cost implications of this proposed 
revision.

D. Packaging Requirements for Nitric Acid (P-1601)

    In P-1601, the United Parcel Service (UPS) requests that PHMSA 
revise the packaging requirements for ground shipments of nitric acid. 
Its petition was based on four loading and sorting operation incidents 
which occurred over a six-month period. The incidents did not result in 
any casualties, but varying degrees of property damage were assessed in 
each situation. UPS notes that each incident involved the same 
packaging configuration--glass inner packagings within fiberboard outer 
packagings. In each case, a breach of one or more inner packagings 
caused leakage, resulting in fumes, followed by the initiation of a 
fire involving the fiberboard outer packaging material. UPS believes 
that the packaging requirements of the HMR applicable to ground 
shipments of nitric acid do not adequately address the hazards present.
    As provided in Sec.  173.158, packaging for ground shipments of 
nitric acid prescribe either outer packaging that is not reactive to 
contents, or a combination packaging that includes non-reactive 
intermediate packaging

[[Page 3792]]

and absorbent material. However, for concentrations of less than 90% 
nitric acid, the HMR permit the use of glass inner packagings of less 
than 2.5 L placed inside UN Specification 4G, 4C1, 4C2, 4D or 4F outer 
packagings. This latter configuration is associated with the four 
incidents referenced by UPS in its petition for rulemaking.
    UPS proposes that PHMSA change Sec.  173.158(e) to enhance the 
packaging requirements applicable to nitric acid in concentrations less 
than 90%. Under the proposal in P-1601, when in wooden or fiberboard 
outer packaging, glass inner packagings used in the configuration 
prescribed in Sec.  173.158(e) would be required to be packed in 
tightly-closed, non-reactive intermediate packagings and cushioned with 
a non-reactive absorbent material. UPS feels that the addition of this 
intermediate packaging would properly address the hazards present in 
this concentration of nitric acid and would have prevented the above 
incidents from occurring.
    The UPS petition identified an increase in the number of fires 
caused by spilled nitric acid reacting with fiberboard packaging. In 
this NPRM, PHMSA is considering a performance standard for packaging 
and handling the product that would prevent breakages and spills 
involving nitric acid. Based on the number of incidents noted in the 
petition for rulemaking and the cost incurred, in response to UPS's 
petition, PHMSA agreed that it merited consideration of a rulemaking 
change. Therefore, PHMSA is proposing to require in Sec.  173.158(e) 
that when nitric acid, in concentrations less than 90%, is placed in 
glass inner packagings to be packaged in wooden or fiberboard outer 
packaging, the glass inner packagings must be packed in tightly-closed, 
non-reactive intermediate packagings and cushioned with a non-reactive 
absorbent material. PHMSA is seeking comment on whether or not this 
proposed packaging should be applied to other similar materials as well 
as cost burdens from the increase in packaging requirements.

E. Pressure Test and Internal Visual Inspection Requirements for MC 331 
Cargo Tanks (P-1604)

    In P-1604, the National Propane Gas Association (NPGA) requests 
PHMSA modify the pressure test and visual inspection test requirements 
applicable to certain MC 331 specification cargo tanks in dedicated 
propane delivery service, commonly known as bobtails, found in Sec.  
180.407(c) . Currently, the HMR require periodic pressure testing and 
visual inspection every five years to remain in service. NPGA petitions 
PHMSA to extend the requalification period for certain MC 331 cargo 
tanks from five years to ten years and provides a technical case for 
this change.
    NPGA states in its petition that the five-year requalification 
period for bobtails is a burden to the propane industry. It states that 
these cargo tanks must be taken out of service for a period of up to a 
week and that water is introduced into the tank during the 
requalification process, which can be detrimental to the tank and 
product contained in the tank. Before a tank can be returned to 
service, it must be completely free of any water. NPGA states that this 
removal from service hinders a propane company's operations.
    In 2001, NPGA conducted a survey to determine whether companies 
that performed the five-year hydrostatic test requirement had 
experienced any failures. None of the 203 survey respondents reported a 
hydrotest failure for tanks of less than 3,500 gallons water capacity. 
Based on the results of this survey, the NPGA sponsored a study by a 
non-profit research and development organization (the Battelle Memorial 
Institute) to determine whether a change to the requalification period 
would be technically feasible. Battelle developed crack growth models 
to estimate the time to failure of a tank that has undergone several 
pressure cycles. They also analyzed effects on the MC 331 cargo tank 
under the delivery service load conditions to determine the estimated 
life of the tank.
    Based on the results of this study, the NPGA and Battelle recommend 
that PHMSA modify the requalification period from five years to ten 
years for MC 331 cargo tanks that: (1) Are used in dedicated propane 
service; (2) have a water capacity less than 3,500 gallons; and (3) are 
constructed of: non-quenched and tempered (NQT) SA-612 steel and NQT 
SA-202 or SA-455 steels, provided the materials have full-size 
equivalent (FSE) Charpy-V notch energy test data that demonstrates 75% 
shear-area ductility at 32[emsp14][deg]F with an average of three or 
more samples greater than 15 ft-lb FSE, and with none less than 10 ft-
lb FSE. A copy of this study is in the docket for this rulemaking.
    After considering the NPGA survey results, which cite no reported 
incidents, and the study commissioned by the NPGA, PHMSA determined 
that the petition merited consideration of a rulemaking change. NPGA 
notes there is a strong safety record amongst its members regarding 
this issue and the cost savings to the industry would be significant (a 
specific benefit was not provided by the NPGA). Therefore, PHMSA is 
proposing to revise the pressure test and internal visual inspection 
requirements found in Sec.  180.407(c) for certain MC 331 Specification 
cargo tanks from a five-year requalification period to a ten-year 
period. PHMSA seeks comment on the safety implications of such a change 
as well as the net benefit such a change (i.e., decrease in time out of 
service) would provide.

F. Mobile Acetylene Trailer Systems (P-1605) and NTSB Safety 
Recommendations H-09-01 and H-09-02

    In P-1605, the CGA requests that PHMSA amend the HMR to incorporate 
a reference to CGA pamphlet G-1.6, Standard for Mobile Acetylene 
Trailer Systems, Seventh Edition (G-1.6, 2011). This standard provides 
minimum requirements necessary for the design, construction, and 
operation of mobile acetylene trailer systems, which consist of 
acetylene cylinders mounted and manifolded for the purposes of 
charging, transporting, and discharging acetylene. It also covers 
ground-mounted auxiliary equipment used with mobile acetylene trailers 
such as piping, meters, regulators, flash arrestors, and fire 
protection equipment.
    This petition coincides with two NTSB recommendations (H-09-01 and 
H-09-02) issued to PHMSA based on incidents involving mobile acetylene 
trailers.\1\ In response to CGA's petition and its appropriateness to 
addressing the NTSB recommendations, PHMSA determined that it warranted 
consideration of a rulemaking change. Further detailed discussion of 
this issue can be found in the Section-by-Section review for Sec.  
173.301.

G. Pressure Relief Devices for Cargo Tanks (P-1609)

    In P-1609, the Truck Trailer Manufacturers Association (TTMA) 
requests that PHMSA amend the Sec.  180.407 requirements applicable to 
pressure relief devices (PRDs). Specifically, TTMA requests that PHMSA 
revise the HMR to more clearly establish the set pressure of a PRD for 
each of the DOT specification cargo tank motor vehicles. TTMA states 
that the wording of Sec. Sec.  180.407(d)(3) and 180.407(g)(1)(ii), 
applicable to the testing requirements for PRDs, creates issues for 
persons performing the testing of a PRD.
    TTMA points out two specific issues with these paragraphs. The 
first is the

[[Page 3793]]

term ``set-to-discharge.'' On April 9, 2009 PHMSA published a final 
rule (Docket No. PHMSA-2006-25910 (HM-218E); 74 FR 16135; effective May 
11, 2009), where in an attempt to harmonize with international 
standards, PHMSA removed the phrase ``set-to-discharge,'' and ``start-
to-discharge'' was substituted in its place. TTMA explains that this is 
an issue because the discharge pressure referenced is used to figure 
the minimum pressure at which the PRD should reseat. By changing the 
wording from ``set'' to ``start,'' the reseating pressure changed from 
a design requirement, to one based on what a given vent actually does 
under test. Therefore, instead of testing a PRD knowing its reseating 
requirements, testers must perform the test of a given PRD and 
calculate the reseating pressure of that particular PRD and retest from 
that pressure. Essentially, testers of PRDs could test identical 
products at different pressures because the reseat pressure is no 
longer a fixed design requirement. This creates inconsistencies between 
the reseating pressures of comparable PRDs authorized for identical 
hazardous materials service. TTMA states that this compromises safety, 
instead of promoting it.
    The second issue TTMA points out in its petition is in regards to 
the term ``the required set pressure.'' This term is problematic in 
relation to the continuing operation of existing cargo tanks made to 
older specifications in Sec.  180.405(c). As the codes for the older 
specifications of cargo tanks are no longer published, determining 
``the required set pressure'' is problematic. This is an issue for 
current specifications of cargo tanks as well. There are pressure 
allowances during the retesting of pressure relief devices of no more 
than 110% of the required set pressure (Sec.  180.407(d)(3)) and the 
same 10% allowance for DOT 400 series cargo tanks (Sec.  178.345-10(d)) 
creates confusion for current specification cargo tanks. TTMA believes 
this will create an unsafe condition for tanks, as a PRD is no longer 
functioning as designed by the manufacturer. The PRD may actually open 
at higher pressures (near a cargo tank's test pressure) as opposed to 
the appropriate lower design pressure.
    TTMA petitions that PHMSA revise the HMR for testing of PRDs by 
replacing the current requirements found in Sec. Sec.  180.407(d)(3) 
and 180.407(g)(1)(ii) with a reference to a new paragraph, Sec.  
180.407(j) which would detail the PRD test requirements. TTMA believes 
this change will eliminate confusion for testers by clarifying the 
requirements for opening and reseating pressures when beginning the 
tests. This will also enhance the enforcement of these requirements by 
creating consistency in the testing requirements for cargo tank PRDs of 
the same design.
    PHMSA determined that TTMA's petition merited consideration of a 
rulemaking change based on the need for consistent and clear testing 
requirements for PRDs on DOT specification cargo tanks. Therefore, 
PHMSA is revising Sec. Sec.  180.407(d)(3) and 180.407(g)(1) to 
reference a new section Sec.  180.407(j), which will outline the 
testing requirements applicable to PRDs.

IV. Section-by-Section Review

Part 107

Section 107.402
    This section sets forth the application requirements for 
designation as a certification agency to issue certificates and 
certifications for packagings designed, manufactured, tested, or 
maintained in conformance with the HMR and standards set forth in the 
UN Model Regulations. This section also sets forth the application 
requirements for designation as a certification agency to issue 
certificates and certifications for lighters, portable tanks, multi-
element gas containers, and Division 1.4G consumer fireworks.
    PHMSA is proposing to revise Sec.  107.402(d)(1)(i) to indicate 
that a fireworks certification agency applicant must be a U.S. 
resident, or for a non-U.S. resident, must have a designated U.S. agent 
representative as specified in Sec.  105.40. The criteria for fireworks 
certification agencies were added to the HMR in Docket No. PHMSA-2010-
0320 (78 FR 42457) (HM-257). PHMSA intended for Sec.  107.402(d)(1)(i) 
to correspond with the requirements of Sec.  105.40, which specifies 
designated agents for non-residents; however, the term ``citizen'' was 
inadvertently substituted for ``resident.'' PHMSA is proposing to 
revise Sec.  107.402(d)(1)(i) by replacing the term ``citizen'' with 
the term ``resident.''
    PHMSA is also proposing to revise Sec.  107.402(e) to require that 
a lighter certification agency submit a statement to the Associate 
Administrator that the agency is independent of and not owned by a 
lighter manufacturer, distributor, import or export company, or 
proprietorship. Further, we propose to revise Sec.  107.402(f) to 
require that a portable tank and MEGC certification agency submit a 
statement to the Associate Administrator indicating that the agency is 
independent of and not owned by a portable tank or MEGC manufacturer, 
owner, or distributor. This language was included in Sec.  107.402 and 
pertained to all certification agencies, but was removed inadvertently 
as a result of changes made to the HMR in Docket No. PHMSA-2010-0320 
(78 FR 42457) (HM-257).
Section 107.807
    This section sets forth the requirements for authorizing chemical 
analyses and tests for non-domestic manufacturers of DOT specification 
or special permit cylinders. To maintain consistency with requirements 
of other independent inspection agencies, PHMSA is proposing to revise 
Sec.  107.807 to require that the agency submit a statement indicating 
that the inspection agency is independent of and not owned by a 
cylinder manufacturer, owner, or distributor.

Part 171

Section 171.7
    The National Technology Transfer and Advancement Act of 1995 (15 
U.S.C. 272) directs agencies to use voluntary consensus standards in 
lieu of government-unique standards except where inconsistent with law 
or otherwise impractical. Section 171.7 lists all standards 
incorporated by reference into the HMR and informational materials not 
requiring incorporation by reference. The informational materials not 
requiring incorporation by reference are noted throughout the HMR and 
provide best practices and additional safety measures that while not 
mandatory, may enhance safety and compliance. Table 1 to Sec.  171.7 
lists informational materials that are not incorporated by reference. 
In a final rule published on January 28, 2008 (Docket No. 05-21812 (HM-
218D); 73 FR 4699, effective October 1, 2008), PHMSA added in Table 1 
(formerly paragraph (b) of the section) an entry for the Compressed Gas 
Association (CGA) publication, CGA C-1.1, Personnel Training and 
Certification Guidelines for Cylinder Requalification by the Volumetric 
Expansion Method. Following the publication of the final rule (HM-
218D), PHMSA received an appeal from Hydro-Test Products, Inc. (PHMSA-
2005 21812-0025) asking us to either remove the reference to CGA C-1.1 
or add examples of other training materials that may be used. Hydro-
Test noted that referencing only the CGA publication in the HMR could 
suggest that other training materials are not acceptable. PHMSA added 
CGA C-1.1 as an example of guidance material that may be used to assist 
requalifiers in creating their cylinder training

[[Page 3794]]

procedures and recordkeeping requirements. The publication is not a 
standalone tool for training persons on how to perform requalification 
of cylinders using the volumetric expansion test method. To alleviate 
confusion for cylinder requalifiers, PHMSA intended to remove the 
reference to CGA C-1.1 in Sec. Sec.  171.7 and 180.205 in a previous 
editorial final rule published on October 1, 2008 (Docket No. PHMSA-
2008-0227 (HM-244A); 73 FR 57001, effective October 1, 2008). However, 
PHMSA removed reference to the document only in Sec.  180.205(g)(6) and 
inadvertently failed to remove the reference in Sec.  171.7. PHMSA is 
proposing to amend Table 1 to Sec.  171.7 to remove the entry for CGA 
C-1.1 to align the regulatory text with previous rulemaking actions.
    Additionally, Sec.  171.7 incorporates by reference the American 
Association of Railroad's (AAR's) Manual of Standards and Recommended 
Practices, Section C-III, Specifications for Tank Cars, Specification 
M-1002 (AAR Specifications for Tank Cars), October 2000 edition for 
various tank car design, manufacture, inspection and testing, and 
qualification regulations set forth in Parts 173, 179, and 180 of the 
HMR. As currently incorporated by reference, all sections refer to the 
October 2000 edition of this document.
    AAR frequently updates the AAR Specifications for Tank Cars. While 
the AAR updates this document, PHMSA has not received a petition for 
rulemaking to revise the HMR to reflect more current versions of the 
AAR Specifications for Tank Cars.
    In this proposed rule, we are proposing to update the incorporation 
by reference for this document to include revisions published by the 
AAR in the 2007 edition of the AAR Specifications for Tank Cars and 
certain subsequent amendments. PHMSA is also proposing to revise Sec.  
179.24(a)(2) to remove the reference to the December 2000 edition of 
this document and instead replace it with a generic reference to the 
AAR Specifications for Tank Cars. Additionally, we are proposing to 
revise Sec.  180.503 to replace the reference to the ``AAR Tank Car 
Manual'' with ``AAR Specifications for Tank Cars'' for consistency with 
references to this document elsewhere in the HMR. The FRA reviewed the 
2007 standard and the subsequent amendments and determined not to 
incorporate the 2007 standard in its totality. Under this proposed 
rule, each chapter and appendix of the AAR Specifications for Tank Cars 
will be listed in Sec.  171.7 with an effective date to account for the 
most recent AAR amendments supported by FRA. In cases where FRA does 
not support amendments made to the AAR Specifications for Tank Cars due 
to safety concerns a prior effective date for that specific chapter or 
appendix will be referenced, and in some cases, specific sections of 
the chapter or appendix will be specifically not included. Upon 
adoption into the HMR, entities subject to compliance with the HMR must 
comply with the version of the chapters and appendices referred to in 
Sec.  171.7 and effective on the date specified therein. AAR 
publications such as this are available through the AAR as a benefit of 
membership. We anticipate that affected entities already have access to 
the AAR Specifications for Tank Cars we are proposing to incorporate. 
Other interested parties may purchase these standards from the AAR for 
$390.00. Moving forward, FRA will continue to evaluate amendments made 
to the AAR Specifications for Tank Cars and will update the effective 
dates for referenced chapters or appendices of the tank car manual, as 
appropriate, when such amendments are supported by FRA.
    Lastly, as described in Section IIF for petition for rulemaking P-
1605 and further discussed in the Section-by-Section review for Sec.  
173.30, PHMSA proposes to amend the HMR to incorporate a reference to 
CGA pamphlet G-1.6, Standard for Mobile Acetylene Trailer Systems, 
Seventh Edition (G-1.6, 2011). Interested parties may purchase a copy 
of this standard from the CGA starting at $37.00.
Section 171.22
    In a May 3, 2007 final rule (Docket No. PHMSA-2005-23141 (HM-215F); 
72 FR 25162), the importer responsibility requirements were 
transitioned from Sec.  171.12(a) to Sec.  171.22. When transitioning 
the requirement that a person importing a hazardous material into the 
United States must provide the shipper and forwarding agent with 
information required under the HMR, the shipper notification was 
inadvertently omitted. As a result, only the forwarding agent is 
presently required to be provided with information as to the 
requirements of the HMR applicable to the particular shipment. In this 
NPRM, PHMSA is proposing to reinstate text in Sec.  171.22(f) that was 
inadvertently removed during the transition by requiring both the 
foreign shipper and forwarding agent at the place of entry to be 
provided with the requirements of the HMR applicable to the particular 
shipment.

Part 172

Section 172.101
    This section contains the HMT and explanatory text for each of the 
columns in the table. In this NPRM, PHMSA is proposing a number of 
revisions to the Sec.  172.101 HMT, including the special provisions 
listed in Column (7) of the table and specified in Sec.  172.102, to 
clarify the regulations and correct inadvertent errors. Proposed 
changes to the Sec.  172.101 HMT will appear as an ``add,'' ``remove,'' 
or ``revise,'' and include changes to the following table entries: 
``Calcium nitrate, UN1454,'' ``Corrosive liquids, flammable, n.o.s., 
UN2920,'' ``Fire extinguishers, UN1044,'' ``Oxidizing solid, corrosive, 
n.o.s., UN3085,'' ``Propellant solid, UN0501,'' ``Trinitrophenol 
(picric acid), wetted, with not less than 10 percent water by mass, 
UN3364,'' and ``Trinitrophenol, wetted with not less than 30 percent 
water, by mass, UN1344.''
    The entry for ``Calcium nitrate, UN1454'' is being revised to 
reflect a change that was intended to be made when PHMSA published a 
final rule on January 7, 2013 (Docket No. PHMSA-2012-0027 (HM-215L); 78 
FR 987). Special Provision B120 was inadvertently not assigned to the 
entry for ``Calcium nitrate, UN1454'' when several HMT other entries 
were revised to include Special Provision B120. Special Provision B120 
indicates that the material, when offered in conformance with the 
applicable requirements of Part 178 and general packaging requirements 
in Part 173, may be offered for transportation in a flexible bulk 
container. PHMSA is proposing to revise the HMT to add Special 
Provision B120 to Column (7) for the entry ``Calcium nitrate, UN1454.''
    The entry for ``Corrosive liquids, flammable, n.o.s., UN2920'' is 
being revised to harmonize the HMR with the UN Model Regulations, IMDG 
Code, and the ICAO TI. The UN Model Regulations, IMDG Code, and ICAO TI 
provide limited quantity exceptions for the PG II entry. Therefore, 
PHMSA is proposing to revise the entry for ``Corrosive liquids, 
flammable, n.o.s., UN2920, PG II'' to remove the word ``None'' from 
Column (8A) of the HMT and add ``154.'' This change will be consistent 
with similar PG II materials that are also provided the limited 
quantity exception.
    The entry for ``Fire extinguishers, UN1044'' is being revised to 
eliminate reference to a Special Provision 18 which is no longer in the 
HMR. Special Provision 18 was removed from

[[Page 3795]]

Sec.  172.102(c)(1) in a January 7, 2013 final rule (Docket No. PHMSA-
2009-0126 (HM-215K); 78 FR 1101) and combined into revised Sec.  
173.309(a). We did not make a conforming amendment to remove Special 
Provision 18 from this entry in the HMT, thus, in this NPRM, we are 
proposing to revise the entry for ``Fire extinguishers, UN1044'' by 
deleting the special provision.
    The entry for ``Oxidizing solid, corrosive, n.o.s., UN3085'' is 
being revised to harmonize with the UN Model Regulations, IMDG Code, 
and the ICAO TI. The UN Model Regulations, IMDG Code, and ICAO TI 
provide limited quantity exceptions for the PG II entry. Therefore, 
PHMSA is proposing to revise the entry for ``Oxidizing solid, 
corrosive, n.o.s., UN3085, PG II'' to remove the word ``None'' from 
Column (8A) of the HMT and add ``152.''
    The entry for ``Propellant, solid, UN0501' is being revised to 
eliminate a reference to a requirement that is no longer is in the HMR. 
Column (10B) of this entry lists vessel stowage provision 24E. Vessel 
stowage provision 24E was removed from Sec.  176.84(c)(2) when the 
Research and Special Programs Administration (RSPA), PHMSA's 
predecessor, published a final rule on June 21, 2001 (Docket No. RSPA-
2000-7702 (HM-215D); 66 FR 33316, effective October 1, 2001) that 
revised the table of provisions applicable to vessel transportation of 
Class 1 (explosive) materials. As this provision is no longer in the 
HMR, PHMSA is proposing to revise the entry for ``Propellant, solid, 
UN0501'' to remove vessel stowage provision 24E from Column (10B) of 
the HMT.
    The HMT entries for ``Trinitrophenol (picric acid), wetted, with 
not less than 10 percent water by mass, UN3364'' and ``Trinitrophenol, 
wetted with not less than 30 percent water, by mass, UN1344,'' are 
being revised to harmonize the HMR with the UN Model Regulations, IMDG 
Code, and the ICAO TI. Presently, Special Provision 162 is applied to 
UN3364 (not less than 10 percent water) and Special Provision 23 is 
applied to UN1344 (not less than 30 percent water). Special Provision 
162 outlines a provision for transport of the material as a Division 
4.1. The material must be packed such that at no time during transport 
will the percentage of diluent fall below the percentage that is stated 
in the shipping description. Special Provision 23 is similar in that it 
also outlines this provision but includes an additional condition that 
quantities of not more than 500 grams per package with not less than 10 
percent water by mass may also be classed in Division 4.1, provided a 
negative test result is obtained when tested in accordance with test 
series 6(c) of the UN Manual of Tests and Criteria.
    The special provisions are assigned in the reverse manner to the 
trinitrophenol entries in the UN Model Regulations, IMDG Code, and the 
ICAO TI. Special Provision 23 is applied to UN3364 with the lower 
minimum diluent percent of water while the 500 gram limit per package 
for 10% diluent does not apply to UN1344 with the larger minimum 
diluent percentage of water (i.e., 30%). Thus the special provision was 
inadvertently incorrectly assigned in the HMR. For the entry 
``Trinitrophenol (picric acid), wetted, with not less than 10 percent 
water by mass, UN3364,'' we propose to replace Special Provision 162 in 
Column (7) of the HMT with Special Provision 23. Conversely, for the 
entry ``Trinitrophenol, wetted, with not less than 30 percent water, by 
mass, UN1344,'' we propose to replace Special Provision 23 from Column 
(7) of the HMT with Special Provision 162.
Section 172.102
    This section outlines special provisions that are listed in Column 
(7) of the Sec.  172.101 HMT. Special Provision 136 is listed for the 
entry ``Dangerous Goods in Machinery or Dangerous Goods in Apparatus, 
UN3363.'' PHMSA received a request for a letter of interpretation (Ref. 
No. 12-0037) which sought confirmation that a material classified as a 
Class 2 gas that has packaging exceptions listed in Column (8A) of the 
HMT may be described as ``Dangerous Goods in Apparatus, UN3363.'' The 
requestor pointed out that the provisions in Special Provision 136 are 
inconsistent. Special Provision 136 states that except when approved by 
the Associate Administrator, machinery or apparatus may only contain 
hazardous materials for which exceptions are referenced in Column (8) 
of the HMT and are provided in Part 173, Subpart D of Subchapter C. 
Subpart D of Part 173 contains the definitions, classification, packing 
group assignments and exceptions for hazardous materials other than 
Class 1 and Class 7. However, preparation, packaging and exceptions for 
Class 2 gases are located in Subpart G of Part 173. This should be 
indicated in Special Provision 136 to eliminate confusion that gases 
prepared in accordance with Subpart G of Part 173 would not be eligible 
to be described as ``Dangerous Goods in Apparatus, UN3363.'' It was not 
PHMSA's intention to exclude Class 2 gases from using this proper 
shipping name, therefore, PHMSA is proposing to revise Special 
Provision 136 in Sec.  172.102 to include reference to subpart G of 
part 173.
Section 172.201
    This section prescribes the requirements for the preparation and 
retention of shipping papers. Paragraph (d) of this section states the 
requirements for shipping papers to contain an emergency response 
telephone number. This paragraph states that except as provided in 
Sec.  172.604(c), a shipping paper must contain an emergency response 
telephone number. The reference in this paragraph to Sec.  172.604(c) 
is inaccurate. The requirements in Sec.  172.604 applicable to 
emergency response telephone numbers were changed when PHMSA published 
a final rule on October 19, 2009 (Docket No. PHMSA-2006-26322 (HM-
206F); 74 FR 53413, effective November 18, 2009). This rulemaking 
action moved the exceptions to the requirement to provide an emergency 
response telephone number to a new paragraph (d). PHMSA is proposing a 
conforming revision to Sec.  172.201(d) to accurately reference the 
exception from the emergency response telephone number requirement 
found in Sec.  172.604(d).
Sections 172.301, 172.326, 172.328, and 172.330
    These sections prescribe marking requirements for non-bulk 
packagings, portable tanks, cargo tanks, tank cars and multi-unit tank 
car tanks. Each of these sections contains a paragraph (Sec. Sec.  
172.301(f), 172.326(d), 172.328(e), and 172.330(c)) prescribing 
requirements for legible marking of packages containing unodorized LPG 
with NON-ODORIZED or NOT-ODORIZED. PHMSA received a request for a 
letter of interpretation (Ref. No. 06-0235) requesting clarification 
that the NON-ODORIZED or NOT-ODORIZED mark may also appear on a package 
containing odorized LPG. In the letter, we noted that PHMSA addressed 
this issue in part in a final rule published by its predecessor agency, 
RSPA, on November 4, 2004 (RSPA-03-15327 (HM-206B); 69 FR 64462, 
effective October 1, 2006). Final rule HM-206B changed the hazard 
communication requirements applicable to certain packages containing 
unodorized LPG, including the requirement to mark with NON-ODORIZED or 
NOT-ODORIZED. Specifically, it also clarified that the NON-ODORIZED or 
NOT-ODORIZED marking may appear on a tank car or multi-unit tank car 
tanks used for both unodorized and odorized LPG. This was implemented 
to address the concerns

[[Page 3796]]

expressed by a commenter to the rule about the logistics of tracking, 
inspecting, and stenciling tank cars to ensure proper marking. However, 
this clarification was not extended to cylinders, cargo tanks and 
portable tanks containing LPG in that final rule. We further noted in 
the response letter that we intended to revisit this issue in a future 
rulemaking to extend this clarification to other packaging types that 
are filled with unodorized or odorized LPG.
    We see no compelling argument not to extend this allowance further 
to other packaging types, thus, PHMSA is proposing to revise Sec. Sec.  
172.301(f), 172.326(d) and 172.328(e) to include the clarification that 
the marking may appear on these packagings used for both unodorized and 
odorized LPG, and remove the effective date of October 1, 2006 that 
appears in these paragraphs, as the effective date has long passed. 
PHMSA is also removing the effective date referenced in paragraph Sec.  
172.330(c).
Section 172.406
    This section specifies the placement of labels on a package. 
Paragraph (d) of this section prescribes requirements that labels be 
printed or affixed to a background of contrasting color, or must have a 
dotted or solid line outer border. Further, Sec.  172.407(b)(2) 
provides that the dotted line border on each label shown in Sec. Sec.  
172.411 through 172.448 is not part of the label specification, except 
when used as an alternative for the solid line outer border to meet the 
requirements of Sec.  172.406(d). Based on this language, it appears 
that labels with a dotted or solid line outer border are permitted only 
if the surface of the package is not a contrasting color.
    In this rulemaking, we are proposing to amend Sec.  172.406(d) by 
expressly authorizing the use of labels described in Part 172, Subpart 
E with a dotted or solid line outer border on a surface background of 
contrasting color. There is no reduction in hazard communication and 
this revision will provide cost savings to shippers by eliminating the 
need to acquire and store two types of labels (one with a border and 
the other without) depending on the surface color of the package.
Section 172.407
    This section contains label specifications. Paragraph (d) of this 
section contains color specifications for labels including a 
requirement for color tolerances according to color charts referenced 
in Appendix A to Part 172 of the HMR. Paragraph (d)(4)(ii) states that 
the color charts are on display at the Office of Hazardous Materials 
Safety, Office of Hazardous Materials Standards, Room 8422, Nassif 
Building, 400 Seventh Street SW., Washington, DC 20590-0001. This 
address does not reflect the current address of the Office. PHMSA is 
amending the address in Sec.  172.407(d)(4)(ii) to read Standards and 
Rulemaking Division, Pipeline and Hazardous Materials Safety 
Administration, U.S. Department of Transportation, East Building, 1200 
New Jersey Avenue SE., Washington, DC 20590-0001.
Section 172.514
    This section prescribes the placarding requirements and exceptions 
for a bulk packaging containing a hazardous material. In paragraph 
(c)(4), an exception is provided for an IBC that is labeled in 
accordance with Part 172, Subpart E instead of placarded. IBCs that are 
labeled instead of placarded are authorized to display the proper 
shipping name and UN identification number in accordance with the bulk 
package marking size requirements of Sec.  172.302(b)(2) in place of 
the UN number on an orange panel, placard or white square-on-point. 
Section 172.302(b)(2) requires that for IBCs, markings have a width of 
at least 4.0 mm (0.16 inch) and a height of at least 25 mm (one inch). 
This is inconsistent with the UN Model Regulations, IMDG Code, and ICAO 
TI that all require a height of 12 mm (0.47 inch). The international 
size requirement is equivalent to the non-bulk marking size requirement 
provided in Sec.  172.301(a)(1). In addition, the reference to the bulk 
packaging marking requirements of Sec.  172.302(b)(2) in Sec.  
172.514(c)(4) conflicts with Sec.  172.336(d) identification number 
marking requirements which states ``[w]hen a bulk packaging is labeled 
instead of placarded in accordance with Sec.  172.514(c) of this 
subchapter, identification number markings may be displayed on the 
package in accordance with the marking requirements of Sec.  
172.301(a)(1) of this subchapter.''
    In this rulemaking, we are proposing to clarify that the marking 
size requirement, for both the proper shipping name and identification 
number, is at least 12 mm (0.47 inch) for an IBC that is labeled 
instead of placarded. PHMSA proposes replacing the bulk package marking 
reference in Sec.  172.514(c) with the non-bulk marking reference, 
specifically, Sec.  172.301(a)(1). The reduced minimum marking size 
will alleviate the existing discrepancy between Sec.  172.514(c)(4) and 
Sec.  172.336(d) and decrease frustration of shipments by harmonizing 
with international regulations thus ensuring IBC's marked in accordance 
with these regulations are consistent with the HMR.

Part 173

Section 173.4a
    This section prescribes the requirements for excepted quantities of 
hazardous materials. The excepted quantities provisions were added to 
the HMR when PHMSA published a final rule on January 14, 2009 (Docket 
Nos. PHMSA-2007-0065 (HM-224D) and PHMSA-2008-0005 (HM-215J); 74 FR 
2254, effective February 13, 2009) in an effort to harmonize with 
international standards. Excepted quantities provisions in Sec.  173.4a 
are intended to be consistent with the existing exception in the ICAO 
TI. Paragraph (a) reads ``[e]xcepted quantities of materials other than 
articles transported in accordance with this section are not subject to 
any additional requirements of this subchapter except for . . .'' This 
language is unclear as to whether articles (including aerosols) may use 
the excepted quantities provisions. PHMSA is revising this paragraph to 
clarify that articles (including aerosols) are not eligible for 
excepted quantity reclassification under Sec.  173.4a, although some 
aerosols are eligible to be shipped as small quantities by highway and 
rail in Sec.  173.4. This will eliminate confusion as to the status of 
articles (including aerosols) in the context of this exception, while 
providing consistent language structure with part 3, chapter 5, section 
5.1 of the ICAO TI.
Section 173.21
    This section outlines forbidden materials and packages. Paragraph 
(e) of this section forbids transport of a material in the same 
packaging, freight container, or overpack with another material, that 
if mixed would likely cause a dangerous evolution of heat, flammable or 
poisonous gases or vapors, or produce corrosive materials. While this 
prohibition prevents incidents from occurring within a freight 
container, overpack or the same container, there is no prohibition on 
this type within a transport vehicle (e.g., a truck with single 
trailer). A transport vehicle is defined in Sec.  171.8 as a cargo-
carrying vehicle such as an automobile, van, tractor, truck, 
semitrailer, tank car or rail car used for the transportation of cargo 
by any mode. Each cargo-carrying body is a separate transport vehicle. 
Allowing materials within a single cargo-carrying body (e.g., a 
trailer, a rail car, etc.) that, if mixed, could cause a

[[Page 3797]]

dangerous evolution of heat, flammable or poisonous gases or vapors, or 
create corrosive materials poses a significant safety risk. This method 
of transportation is forbidden within a freight container, packaging, 
or overpack, and while a transport vehicle is slightly different than a 
packaging or overpack, it is similar to a freight container.
    PHMSA received a request for a letter of interpretation (Ref. No. 
13-0111) describing a potentially dangerous situation. In the letter, 
the requestor described a scenario whereby a company offers for 
transportation ``UN1908, Chlorite Solution, Class 8, Packing Group (PG) 
II;'' ``UN1791, Hypochlorite Solutions, Class 8, PG III;'' and 
``UN1789, Hydrochloric Acid Solution, Class 8, PG II'' in separate 
intermediate bulk containers (IBCs) in the same transport vehicle. 
While there are no formal segregation requirements per Sec.  177.848 of 
the HMR, data accompanying the letter indicated that in the event of 
commingling, these materials would create chlorine dioxide gas. 
``Chlorine dioxide (not hydrate)'' is forbidden for transportation per 
the Sec.  172.101 HMT. Thus, the transportation of these materials in 
the same transport vehicle would create a situation where the mixing of 
the materials would produce a poisonous gas and highly corrosive 
material, which happens to also be forbidden from transport; yet, under 
the current construct of Sec.  173.21, there is no prohibition against 
this transport scenario.
    The concern is that a single cargo-carrying body, such as a trailer 
or rail car, does not provide a level of safety equivalent to if these 
materials were intended to be in the same freight container, yet it is 
permitted in the HMR. Additionally, the loading and unloading 
requirements for Class 8 materials in Sec.  177.839 or part 174 do not 
address the loading of chlorite solutions and hypochloric acid in the 
same transport vehicle.
    Prohibiting the transportation or offering for transportation of 
materials in the same transport vehicle (e.g., a trailer, a rail car) 
with another material which is likely to cause a dangerous evolution of 
heat, flammable or poisonous gases or vapors, or produce corrosive 
materials upon mixing would address the safety risk referenced in the 
letter of interpretation Ref. No. 13-0111, for both rail and highway 
transport. This change would afford these modes of transportation the 
same level of safety seen in intermodal transportation and the 
forbidden materials restrictions for freight containers. Therefore, 
PHMSA is proposing to revise Sec.  173.21(e) to include the term 
transport vehicle.
Section 173.24a
    Section 173.24a prescribes additional general requirements for non-
bulk packages. Paragraph (c)(1)(iv) provides the quantity limits for 
mixed contents packages (when multiple hazardous materials are packed 
within the same package) transported by aircraft. In this rulemaking, 
we are proposing to clarify that the requirements provided in paragraph 
(c)(1)(iv) do not apply to limited quantity materials packaged in 
accordance with Sec.  173.27(f)(2). This change is proposed for 
clarification purposes only. Misapplication of Sec.  173.24a(c)(1)(iv) 
would be duplicative and, in certain cases, would place unintended 
restrictions on the net quantity of hazardous materials per package.
Section 173.27
    This section prescribes general requirements for the transportation 
of hazardous material by aircraft. Paragraph (f)(2) contains the 
provisions for limited quantities but does not expressly address 
limited quantity packages of mixed contents. PHMSA received a request 
for a letter of interpretation (Ref. No. 13-0094) to clarify, for 
transportation by aircraft, the applicable section to reference. 
Specifically, the requester asked whether Table 3 in Sec.  
173.27(f)(3), or the general provisions in Sec.  173.24a(c)(1)(iv) 
should be used when determining the maximum net quantity of each inner 
and outer packaging for limited quantity packages of mixed contents. In 
response, we stated that as provided in Sec.  173.27(f)(2), when a 
limited quantity of a hazardous material is packaged in a combination 
packaging and is intended for transportation aboard an aircraft, the 
inner and outer packagings must conform to the quantity limitations set 
forth in Table 3. Table 3 provides the maximum net quantity of each 
inner and outer packaging for materials authorized for transportation 
as a limited quantity by aircraft. For mixed contents of limited 
quantities by air, the shipper must comply with the maximum authorized 
net quantity of each outer package (column 4 of 5 in Table 3) and 
ensure that the total net quantity does not exceed the lowest permitted 
maximum net quantity per package as shown by hazard class or division 
for the hazardous materials in the mixed contents package.
    In this rulemaking, we are proposing to revise Sec.  
173.27(f)(2)(i) to clarify that the maximum net quantity for limited 
quantity packages of mixed contents must conform to the quantity 
limitations provided in Sec.  173.27(f)(3), Table 3.
Section 173.150
    This section provides exceptions for Class 3 (flammable and 
combustible liquid) hazardous materials. The requirements for 
combustible liquids in bulk packagings are found in Sec. Sec.  
173.150(f)(3). Although placarding under Subpart F of Part 172 is 
specified as a requirement in Sec.  173.150(f)(3)(iv), registration 
requirements of Sec.  107.601 are not included among the subject 
requirements. Given that Sec.  173.150(f)(3) provides a list of subject 
requirements for combustible liquids in bulk packaging, PHMSA is 
revising this section by adding a new subparagraph Sec.  
173.150(f)(3)(xi) stating that the registration requirements in Subpart 
G of Part 107 are also applicable, for bulk packagings only. PHMSA is 
also revising Sec. Sec.  173.150(f)(3)(ix) and 173.150(f)(3)(x) for 
punctuation applicable to the listing of requirements.
Section 173.159
    This section prescribes requirements applicable to the 
transportation of electric storage batteries containing electrolyte 
acid or alkaline corrosive battery fluid (i.e., wet batteries). This 
section outlines packaging requirements, exceptions for highway or rail 
transport, and tests which batteries must be capable of withstanding to 
be considered as non-spillable. However, there are no requirements or 
instructions for shippers of damaged or leaking wet batteries to 
prepare these items for transport. PHMSA received a request for a 
letter of interpretation (Ref. No. 06-0031) to clarify whether a 
shipper of a damaged wet battery may utilize the exception from full 
regulation provided in Sec.  173.159(e). In response, we stated that a 
damaged battery may be shipped in accordance with Sec.  173.159(e) 
provided: (1) It has been drained of battery fluid to eliminate the 
potential for leakage during transportation; (2) it is repaired and/or 
packaged in such a manner that leakage of battery fluid is not likely 
to occur under conditions normally incident to transportation; or (3) 
the damaged or leaking battery is transported under the provisions of 
Sec.  173.3(c).
    PHMSA is proposing to create a new paragraph (j) in Sec.  173.159 
to address the need for provisions that allow shippers to prepare for 
transport and offer into transportation damaged wet electric storage 
batteries. This paragraph will permit the transportation, by highway or 
rail, of damaged wet electric storage batteries under the conditions 
outlined

[[Page 3798]]

in the letter of interpretation. In addition to the conditions listed 
in paragraph (j), damaged wet electric storage batteries must also meet 
all other applicable requirements of Sec.  173.159.
Section 173.166
    This section prescribes requirements applicable to the 
transportation of air bag inflators, air bag modules, and seat-belt 
pretensioners. In a final rule (Docket No. PHMSA-2010-0201 (HM-254)) 
published on July 30, 2013 (78 FR 45880), PHMSA revised the 
requirements applicable to these materials. Among the changes made was 
the adoption of Special Permit DOT SP-12332 into the HMR, This special 
permit excepted Class 9 air bag inflators, air bag modules, or seat-
belt pretensioners assigned to UN3268 from the requirement to provide 
the EX number (i.e., the approval number) on the shipping paper.
    Under Sec.  173.166, paragraph (e)(6) authorizes packaging 
alternatives for air bag inflators, air bag modules, and seat-belt 
pretensioners that have been removed from, or were intended to be used 
in, a motor vehicle; and those devices meet the requirements for use in 
the United States and are being transported to recycling or waste 
disposal facilities. When adopted in HM-254, a provision in Sec.  
173.166 (e)(6) stated ``for domestic transportation by highway'' 
thereby limiting the use of this exception to ground transport, yet DOT 
SP-12332 specifically permitted transport by ``cargo vessel'' as an 
authorized mode of transportation. For greater consistency with the 
special permit language adopted in HM-254, PHMSA is revising paragraph 
(e)(6) to add the words ``or cargo vessel.''
Sections 173.170 and 173.171
    These sections prescribe exceptions for the transportation of black 
powder for small arms classed as a Division 1.1 explosive and smokeless 
powder for small arms classed as a Division 1.3 explosive. These 
exceptions permit these materials to be reclassed as Division 4.1 
flammable solid material for domestic transportation. In both sections, 
the total quantity of black or smokeless powder for small arms is 
limited to 45.4 kg (100 pounds) net mass in a motor vehicle (other 
modes are authorized as well). PHMSA believes the exception should be 
updated to account for modern highway transportation. Currently, the 
HMR defines motor vehicle in Sec.  171.8 to include a vehicle, machine, 
tractor, trailer, or semitrailer, or any combination thereof. The use 
of the term motor vehicle in this exception limits a carrier with 
multiple trailers to 100 pounds total of black or smokeless powder, 
reclassed as Division 4.1. Carriers who commonly transport double or 
triple trailer loads by highway may find it difficult to ensure that 
each trailer contains an amount of black or smokeless powder, reclassed 
as Division 4.1 that would keep the total quantity in all trailers 
under 100 pounds.
    PHMSA believes the term motor vehicle should be replaced with 
transport vehicle in the context of this exception and we believe doing 
so will not decrease the level of safety for the transport of these 
materials. The term transport vehicle is defined in Sec.  171.8 as a 
cargo-carrying vehicle such as an automobile, van, tractor, truck, 
semitrailer, tank car or rail car used for the transportation of cargo 
by any mode. Each cargo-carrying body (a trailer, a rail car, etc.) is 
a separate transport vehicle. Changing the term motor vehicle to 
transport vehicle would reflect a consistency in the ability to use 
exceptions for black or smokeless powder with the other modes, such as 
rail and vessel, whereby each rail car or freight container is 
permitted to have 100 pounds total. Thus, PHMSA proposes to revise 
Sec. Sec.  173.170 and 173.171 to replace the term ``motor vehicle'' 
with ``transport vehicle.'' Additionally, PHMSA is requesting specific 
comment from stakeholders on this issue and any data they have relating 
to noted incidents involving transporting black or smokeless powder for 
small arms reclassed as Division 4.1 by motor vehicle.
Section 173.199
    This section prescribes the packaging requirements for Category B 
infectious substances. Paragraph (a)(4) of this section requires that 
the packaging be capable of successfully passing the drop test in Sec.  
178.609(d) and the steel rod impact test in Sec.  178.609(h) at a drop 
height of at least 1.2 meters (3.9 feet).
    PHMSA received a request for a letter of interpretation regarding 
the test requirements in Sec.  173.199(a)(4) (Ref. No. 07-0018). The 
request pointed out that in the preamble to the final rule published on 
June 2, 2006 under Docket Number PHMSA-2004-16895 (HM-226A) [71 FR 
32244], we state that Category B packagings must be capable of passing 
a drop test, but need not be capable of passing a puncture or other 
performance test. The requester asked if the regulatory text requiring 
the steel rod impact test for this packaging was an error.
    As we clarified in our response, PHMSA did not intend to require 
the steel rod impact test in Sec.  178.609(h) for a packaging used to 
transport a Category B infectious substance. Therefore, in this 
rulemaking, we are proposing to revise the provisions in Sec.  
173.199(a)(4) by removing the reference to the steel rod impact test in 
Sec.  178.609(h).
Section 173.216
    This section establishes the transportation requirements for blue, 
brown, or white asbestos. Paragraph (c) of this section provides 
packaging requirements for asbestos including both ``non-bulk'' and 
``bulk'' packaging options.
    PHMSA received a request for a letter of interpretation regarding 
the applicability of bulk and non-bulk packaging instructions for 
asbestos (Ref. No. 11-0169). The letter expressed confusion regarding 
whether Sec.  173.216 should apply to both ``bulk'' and ``non-bulk'' 
packages of asbestos, because as the requester noted in the letter, in 
the Sec.  172.101 HMT, the entry for ``Asbestos,'' NA2212 refers to 
packaging instructions specified in Sec.  173.216 for non-bulk 
packaging requirements, and Sec.  173.240 for bulk packaging 
requirements. It was also noted in the letter that some of the 
packaging options specified in Sec.  173.216 are considered bulk 
packagings.
    PHMSA acknowledged that some of the packaging options provided in 
Sec.  173.216(c) meet the bulk packaging definition specified in Sec.  
171.8 and, therefore, would be considered a bulk packaging for 
transportation purposes. In this rulemaking, we are proposing to amend 
the bulk packaging section reference in Column (8C) of the HMT from 
``240'' to ``216'' for the table entries associated with the following 
identification numbers: NA2212, UN2212, and UN2590. In addition, we are 
proposing to revise paragraph (c)(1) in Sec.  173.216 by authorizing 
the use of bulk packages prescribed in Sec.  173.240. These proposed 
amendments will: (1) Eliminate the confusion pertaining to bulk 
packaging specifications contained in a section referenced in the 
authorized non-bulk Column (8B) of HMT; and (2) allow for the continued 
use of bulk packages in Sec.  173.240, while also providing examples of 
specific bulk packagings authorized for asbestos such as hopper-type 
rail cars and hopper-type motor vehicles currently found in Sec.  
173.216(c)(1).
Section 173.225
    This section contains the packaging requirements and other 
provisions applicable to the transportation of organic peroxides. 
Paragraph (d) of this section contains the Packing Method table, which 
provides packagings

[[Page 3799]]

authorized for organic peroxides and the maximum quantity permitted in 
each package or packaging. The table is missing information and PHMSA 
is proposing to revise the table to add a reference to note 1 for OP2, 
which states that if two values are given, the first applies to the 
maximum net mass per inner packaging and the second to the maximum net 
mass of the complete package. Additionally, PHMSA is proposing to 
revise the maximum quantity for solids and combination packagings 
(liquid and solid) for OP4. This quantity should read as ``5/25'' kg 
instead of only ``5.''
Section 173.301
    This section applies to general requirements for shipment of 
compressed gases and other hazardous materials in cylinders, UN 
pressure receptacles and spherical pressure vessels. Paragraph (g) of 
this section describes the requirements to manifold cylinders in 
transportation. A manifold system is a single pipe or chamber connected 
to a group of cylinders, which allows for a single point of loading and 
unloading.
    Incidents investigated by the NTSB have highlighted potential risks 
when transporting manifolded acetylene trailers.\2\ These incidents 
included overturned vehicles and two unloading releases. As a result of 
the impact caused by ejection of the cylinders from the vehicle during 
overturn incidents, cylinders have shown signs of broken valves, burst 
heads, burst walls, as well as bulging and denting of the walls. The 
impact resulting from the ejection of the cylinders from the vehicle 
also can cause the valves to break, which may ignite the acetylene. The 
NTSB's investigation also concluded that the unloading sequence is 
occasionally done out of order from what is specified in the standard 
operating procedures and this can be a contributing factor to 
incidents.

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

    These recent incidents involving manifolded acetylene trailers have 
caused the National Transportation Safety Board (NTSB) to issue two 
Safety Recommendations (H-09-01 and H-09-02) to PHMSA.\3\ The NTSB 
investigations resulted in the issuance of the following Safety 
Recommendations:

    \3\ https://phmsa.dot.gov/staticfiles/PHMSA/DownloadableFiles/Files/NTSB%20Files/H_09_1_2_Original.pdf.
---------------------------------------------------------------------------

    H-09-01: Modify 49 CFR 173.301 to clearly require (1) that 
cylinders be securely mounted on mobile acetylene trailers and other 
trailers with manifolded cylinders to reduce the likelihood of 
cylinders being ejected during an accident and (2) that the cylinder 
valves, piping, and fittings be protected from multidirectional 
impact forces that are likely to occur during highway accidents, 
including rollovers.
    H-09-02: Require fail-safe equipment that ensures that operators 
of mobile acetylene trailers can perform unloading procedures only 
correctly and in sequence.

    Given the results of the NTSB investigations and the associated 
safety risks of mobile acetylene trailer overturns and unloading 
operations, PHMSA proposes to incorporate by reference in Sec.  171.7 
of the HMR the CGA pamphlet G-1.6-2001, Standard for Mobile Acetylene 
Trailer Systems (7th ed.). CGA G-1.6 would serve to address the NTSB 
Safety Recommendations specific to mobile acetylene trailers. This 
pamphlet was updated with input from PHMSA and the industry to address 
cylinder securement under accident conditions, valve protection from 
multidirectional impact forces and unloading fail-safe procedures 
specific to mobile acetylene trailers.
    Specifically, PHMSA proposes to incorporate the CGA pamphlet into 
Sec.  171.7, and revise Sec.  173.301(g)(1)(iii) to indicate that 
mobile acetylene trailers must be maintained, operated and transported 
in accordance with CGA Pamphlet G-1.6. In addition, PHMSA seeks 
specific comment on the inclusion of CGA Technical Bulletin (TB) TB-25 
to address structural integrity requirements. PHMSA is also proposing 
to revise Sec.  177.840, by adding paragraph (a)(3) to state that 
cylinders containing acetylene and manifolded as part of a mobile 
acetylene trailer system must be transported in accordance with Sec.  
173.301(g) to ensure that this requirement is addressed in the carriage 
by highway portion of the HMR. PHMSA seeks comment on the number of 
entities affected by this proposal, if any. Finally, PHMSA seeks 
comment on safety implications of such a change as well as the net 
benefit such a change (i.e., decrease in the number of frustrated 
shipments) would provide.
Sections 173.304a(d)(5), 173.314(h) and 173.315(b)(1)
    Section 173.304a establishes additional requirements for the 
shipment of LPG in specification cylinders. Section 173.314 establishes 
requirements for compressed gases in tank cars and multi-unit tank cars 
and Sec.  173.315 establishes requirements for compressed gases in 
cargo tanks and portable tanks. PHMSA is aware of several incidents 
possibly attributed to either the under-odorization or odorant fade of 
LPG. Most notable of these incidents is one that happened in Norfolk, 
MA on July 30, 2010 where an explosion occurred at a residential 
condominium complex that was under construction. Emergency responders 
from 21 cities/towns deployed personnel to the accident site. The 
accident resulted in seven injuries and one fatality.
    The subsequent investigation raised questions as to whether there 
was a sufficient level of odorant in the LPG contained in the on-site 
storage tanks. In accordance with Federal and State laws and 
regulations, LPG intended for use by non-industrial entities is 
generally required to be odorized, or stenched, to enable the detection 
of any unintended release or leak of the gas. LPG is highly flammable 
and dangerous to inhale in large quantities. The added odorant is a 
safety precaution that helps warn those in the area that a release of 
gas has occurred. In the Norfolk incident, there appeared to be no 
warning, i.e. there was no noticeable evidence of odorant that would 
indicate the on-site LPG storage tank was leaking prior to the 
explosion. PHMSA has consulted with stakeholders from industry, fire 
fighter associations, and other regulatory agencies in order to better 
understand the root cause of incidents like the one in Norfolk. 
Although additional research may be necessary in order to come to more 
definitive conclusions, PHMSA has identified the following situations 
in which the risks of under-odorization or odorant fade are more likely 
to occur:
    Injection Process: On December 13, 2012, PHMSA met with 
representatives from the National Propane Gas Association (NPGA) to 
gain a better understanding of the LPG odorization process. During this 
meeting, representatives from the NPGA stated that the most common 
method for the odorization of LPG is through an automated system. 
However, the NPGA also noted there are situations where the odorization 
process is manually performed. Preliminary investigations into the 
Norfolk, MA incident suggest that the lack of sufficient odorization 
rendered the LPG undetectable when the on-site storage tank began to 
leak. In situations where the injection process is not fully automated, 
the potential for human error may increase the possibility of under-
odorization. We believe that the insufficient level of odorant in the 
LPG contained in the on-site storage tank involved in the Norfolk, MA 
incident was likely a major contributing factor in limiting the ability 
of on-site personnel to readily detect the leak.

[[Page 3800]]

    New Tanks or Freshly Cleaned Tanks: During our meetings with 
various stakeholders, several indicated that a phenomenon known as 
``odor fade'' may be a problem when new or recently cleaned tanks are 
used. New or recently cleaned tanks may absorb the odorant into the 
metal shell of these tanks leading to an ``odorant fade,'' and thus 
limiting the effectiveness of the remaining odorant in the LPG.
    Odorization Standards: The odorization of LPG is addressed by 
Federal and state laws and regulations, as well as generally accepted 
industry standards and practices. When offered and transported in 
commerce, the HMR specifies that all LPG in cargo and portable tanks be 
effectively odorized using either 1.0 pound of ethyl mercaptan, 1.0 
pound of thiopane, or 1.4 pounds of amyl mercaptan per 10,000 gallons 
of LPG, in the event of an unintended release or leak to indicate the 
presence of gas. The HMR do not, however, require LPG to be odorized if 
odorization would be harmful in the use or further processing of the 
LPG, or if odorization will serve no useful purpose as a warning agent 
in such use or further processing. Essentially, this exception applies 
to LPG being transported to industrial end-users.
    Although the HMR requires odorization of LPG in cargo tanks and 
portable tanks, there are no such parallel requirements in the HMR for 
rail tank car tanks and cylinders. Therefore, in this NPRM, we are 
proposing to add new Sec. Sec.  173.304a(d)(5) and 173.314(h) 
consistent with the revised text in Sec.  173.315(b)(1) to address the 
odorization of LPG in cylinders and rail tank car tanks, respectively. 
We are also proposing to revise Sec.  173.315(b)(1) to add a 
performance standard to address the issues of ``under odorization'' and 
``odor fade.''
Section 173.306
    This section provides exceptions from the HMR for compressed gases, 
including aerosols, when transported in limited quantities. In a final 
rule published May 14, 2010, under PHMSA-2009-0289 (HM-233A) [75 FR 
27205], PHMSA added a new paragraph (k) to Sec.  173.306 adopting 
provisions from DOT-SP 12842. These provisions authorized an increase 
in gross weight per package for the purpose of packaging discarded 
empty, partially used, and full aerosol containers to be transported to 
a recycling or disposal facility.
    PHMSA received a request for a letter of interpretation (Ref. No. 
12-0004) seeking confirmation that aerosols shipped for disposal or 
recycling in compliance with Sec.  173.306(k) are permitted the same 
exceptions (i.e., the marking and labeling requirements of Part 172 
Subparts D and E respectively, and shipping paper requirements, unless 
it is a hazardous waste or hazardous substance, of 172 Subpart C) 
granted under Sec. Sec.  173.306(i) and 173.156(b) without being 
reclassified as an ORM-D material. The requester also pointed out that 
under DOT-SP 12842, aerosols shipped for disposal or recycling were 
excepted from the marking, labeling and shipping paper requirements, 
unless they were considered a hazardous waste or hazardous substance, 
without being reclassified as an ORM-D material.
    PHMSA stated that the intention of HM-233A was to adopt DOT-SP 
12842 into the HMR as was designed. Therefore, in this rulemaking, we 
propose to amend Sec.  173.306(k) by clarifying that aerosols shipped 
for recycling or disposal by motor vehicle, containing a limited 
quantity under the specific conditions provided in Sec.  173.306(k), 
are afforded the applicable exceptions provided for ORM-D materials 
granted under Sec. Sec.  173.306(i) and 173.156(b). The letter provides 
that, consistent with Sec.  173.306(i), packages containing aerosols 
meeting the limited quantity requirements of Sec.  173.306(k) must be 
marked in accordance with Sec.  172.315(b). In addition, the letter 
also clarifies that the language ``INSIDE CONTAINERS COMPLY WITH 
PRESCRIBED REGULATIONS'' is required for shipments of aerosols shipped 
for disposal or recycling in compliance with paragraphs (a)(3), (a)(5), 
or (b)(1) of Sec.  173.306.

Part 175

Section 175.1
    This section describes the purpose, scope and applicability of Part 
175 to air operations, specifically, the transportation of hazardous 
materials in commerce by air. Exceptions for certain aircraft 
operations are listed in Sec.  175.9(b). Paragraph (b)(4) of Sec.  
175.9 excepts hazardous materials carried and used during dedicated air 
ambulance, firefighting, or search and rescue operations. To clarify 
that these operations are not subject to the HMR when in compliance 
with applicable Federal Aviation Regulations (FAR; 14 CFR) and any 
additional FAA requirements, PHMSA proposes to create a new paragraph 
(d) in Sec.  175.1 stating that the HMR does not apply to dedicated air 
ambulance, firefighting, or search and rescue operations. This will 
eliminate any confusion that these air operations would otherwise be 
subject to requirements in the HMR (e.g., passenger notification 
requirements). PHMSA also proposes to remove Sec.  175.9(b)(4) for 
consistency.
    As with other conditional exceptions to the HMR, non-compliance 
with the FAR could subject operators to enforcement under the HMR. 
PHMSA does not anticipate any adverse safety consequences with this 
proposed revision due to the existing training requirements in the FAR 
on the proper handling and stowage of hazardous materials carried 
onboard aircraft.
    The FAA and PHMSA recognize that certain operators do not solely 
utilize their aircraft for purposes under Sec.  175.9(b)(4). Normal 
transport operations (i.e., the transport of either passengers or cargo 
not required for performance of, or associated with, the specialized 
emergency function) would continue to be subject to the HMR. However, 
staging operations and other operations related to dedicated air 
ambulance, firefighting, or search and rescue operations are intended 
to be excepted from the HMR when in compliance with the FAR. We note 
the following definitions in FAA Order 8900.1 (Vol. 3, Chapter 14, 
Section 1, 3-529(C)):

    (1) Firefighting. This term includes the drop of fire 
retardants, water, and smoke jumpers. It also includes the transport 
of firefighters and equipment to a fire or to a base camp from which 
they would be dispersed to conduct the firefighting activities.
    (2) Search and Rescue. Search and rescue is a term of art 
meaning aircraft operations that are flown to locate people who 
cannot be located from the ground. The term includes operations 
where the aircraft is indispensable to the search, or is the only 
feasible means of reaching the victim. Victims would be considered 
to be ``associated with'' the search and rescue operation. The term 
``search and rescue'' does not include routine medical evacuation of 
persons due to traffic accidents and other similar incidents.

    Air ambulance operators are required by the FAR to utilize either 
Operational Specification (OpSpec) A021 ((Helicopter Emergency Medical 
Services (HEMS) Operations) or A024 (Air Ambulance Operations-Airplane) 
and must obtain and adhere to the appropriate OpSpec to be excepted 
from the HMR.
Section 175.8
    This section provides exceptions from certain regulations for air 
carrier operator equipment and items of replacement. Paragraph (b)(1) 
provides that oxygen, or any hazardous material used for the generation 
of oxygen, for

[[Page 3801]]

medical use by a passenger, which is furnished by the aircraft operator 
in accordance with certain 14 CFR requirements is not subject to the 
requirements of the HMR. The provisions of 14 CFR, Sec.  125.219, 
Oxygen for medical use by passengers, was inadvertently left out of 
paragraph (b)(1). In this rulemaking, we are proposing to correct the 
paragraph by adding the appropriate 14 CFR, Part 125 citation.
Section 175.10
    This section provides exceptions for passengers, crewmembers, and 
air operators. Paragraph (a) of this section lists a number of 
hazardous materials that are permitted for carriage by passengers or 
crewmembers provided the requirements of Sec. Sec.  171.15 and 171.16 
and the conditions of this section are met. PHMSA is proposing 
revisions to some of these provisions to promote clarity.
    In paragraph (a)(6), hair curlers (curling irons) containing a 
hydrocarbon gas such as butane and carried in carry-on or checked 
baggage, are excepted from the requirements of the HMR. Gas refills for 
such curlers are not permitted in carry-on or checked baggage. In this 
NPRM, PHMSA proposes to prohibit such hair curlers in checked baggage. 
We believe the risk posed by flammable gases in an inaccessible 
compartment on a passenger-carrying aircraft is obvious. Flammable 
gases will burn if mixed with an appropriate amount of air and confined 
burning of a flammable gas can lead to detonation. As a result, we 
remain concerned with the flammability hazard posed by butane and other 
flammable gases and the ability of such gases to propagate or 
contribute to a fire in the cargo compartment of an aircraft. This 
concern is particularly relevant to carriage in checked baggage where 
damage to the curling iron and the subsequent release of a flammable 
gas may occur if the baggage is mishandled or the article itself is 
compromised.
    Because of the risks posed by flammable gas, a number of safety 
requirements apply to cargo shipments of flammable gas on passenger-
carrying aircraft. Most Division 2.1 flammable gas substances and 
articles are generally forbidden from transportation as cargo aboard 
passenger-carrying aircraft and prohibiting the carriage of butane-
powered curling irons in checked baggage is consistent with this 
provision. In the area of aviation safety, where the high volume of 
travel and the catastrophic consequences of failure lead to a very low 
tolerance for risk, we firmly believe the known risks of flammable gas 
are sufficient basis for our decision. We solicit public comment on any 
impact our proposed action may impose upon passengers, crew members, 
and air operators.
    In paragraph (a)(22) of this section, non-infectious specimens 
transported in accordance with Sec.  173.4b(b) (de minimus quantities) 
are permitted for carriage by passengers or crewmembers. PHMSA is 
clarifying this exception to include the phrase ``in preservative 
solutions'' to clarify the intended use of this exception. Non-
infectious substances would not otherwise be subject to the HMR if they 
did not otherwise meet the definition of any other hazard classes. This 
clarification will signal that the exception refers to specimens in 
solutions that may contain preservatives that are hazardous materials 
such as formaldehyde and alcohol solutions.
    Additionally PHMSA is revising paragraph (a)(24) of this section, 
which refers to small cartridges of carbon dioxide or other suitable 
gas of Division 2.2. The exception states that small cartridges fitted 
into devices with no more than four small cylinders are permitted. This 
is inconsistent with the ICAO TI, which permits cartridges for other 
devices indicating that spares are permitted. As Sec.  175.10(a)(24) 
currently reads, there is no mention of spare cartridges. The HMR 
currently permits up to four small cartridges and therefore, PHMSA is 
proposing to revise this paragraph to state that small cartridges 
fitted into or securely packed with devices with no more than four 
small cylinders of carbon dioxide or other suitable gas in Division 2.2 
are permitted for carriage by passengers or crewmembers. This change 
will harmonize with international standards to clarify that spares are 
permitted in addition to the cartridges already fitted into the device, 
provided they are securely packed with the devices for intended use.
Section 175.75
    This section describes the quantity limitations and cargo locations 
for carriage by aircraft. Paragraph (e)(2) excepts packages of 
hazardous materials transported aboard a cargo aircraft, when other 
means of transportation are impracticable or not available, in 
accordance with procedures approved in writing by the FAA Regional or 
Field Security Office in the region where the operator is located from 
the requirements of paragraphs (c) and (d) of Sec.  175.75. PHMSA is 
revising this paragraph by removing the word ``located'' and adding the 
word ``certificated'' in its place. The words ``or Field Security'' are 
also removed. This amendment will ensure operators interact with the 
Hazardous Materials Division Manager (HMDM) who has already reviewed 
and recommended for approval the certificate's HazMat-related manual(s) 
required under 14 CFR 14 CFR 121.135. The HMDM (or designee) will 
already have an understanding of the certificate's operations and, as 
needed, will interact with the local resources and/or the operator's 
certificate management team to assess the impracticability or lack of 
availability of other cargo operations--as well as what alternative 
procedures should be prescribed.

Part 176

Section 176.30
    This section prescribes the information required on dangerous cargo 
manifests for vessel transport. Paragraph (a)(4) requires ``the number 
and description of packages (barrels, drums, cylinders, boxes, etc.) 
and gross weight for each type of packaging.'' In this rulemaking, we 
are proposing to replace the word ``packaging'' with ``package'' as the 
term ``packaging'' refers to the means of containment and not the 
completed package.

Part 177

Section 177.848
    This section addresses segregation requirements for hazardous 
materials transported by motor carrier. PHMSA received a request for a 
letter of interpretation (Ref. No. 09-0268) requesting clarification 
whether ``UN0042, Boosters, 1.1D, PG II'' and ``UN1942, Ammonium 
nitrate, 5.1, PG III'' can be transported in the same vehicle. The 
requester noted seemingly conflicting requirements in Sec. Sec.  
177.835 and 177.848 applicable to the segregation of ammonium nitrate 
fertilizer and explosive materials.
    Section 177.848(e) provides instructions for using the segregation 
table in Sec.  177.848(d). Presently, under Sec.  177.848(e)(5) 
assignment of note ``A'' authorizes ammonium nitrate (UN1942) and 
ammonium nitrate fertilizer to be loaded or stored with Division 1.1 
(explosive) or Division 1.5 materials. However, Sec.  177.835(c) 
provides that Division 1.1 or 1.2 (explosive) materials may not be 
loaded into or carried on any vehicle or a combination of vehicles 
under certain conditions outlined in paragraphs (c)(1) through (c)(4). 
PHMSA clarified in the letter that a Division 1.1 or 1.2 explosive may 
not be loaded into or carried on any vehicle or a combination of 
vehicles that does not conform to Sec. Sec.  177.835(c)(1) through (4), 
regardless of the note ``A'' exception for

[[Page 3802]]

UN1942 in Sec.  177.848(e)(5). In this rulemaking, we are proposing to 
clarify that the loading restrictions in Sec.  177.835(c)(1) through 
(4) are applicable to Sec.  177.848(e).

Part 178

Section 178.65
    This section applies to the manufacture of DOT Specification 39 
non-reusable (non-refillable) cylinders. Paragraph (i) of this section 
describes the required markings for DOT 39 cylinders. The reference to 
Sec.  178.35(h) in Sec.  178.65(i)(1) is incorrect, as Sec.  178.35(h) 
was removed under a final rule published July 20, 2011 (Docket No. 
PHMSA-2009-0151 (HM-218F). The final rule consolidated the inspector's 
report requirements found in Sec.  178.35(g) into paragraph (c)(4) of 
that section, moved the manufacturer's report retention requirements 
into paragraph (g) and removed paragraph (h). PHMSA is proposing to 
revise Sec.  178.65(i)(1) to correctly reference the manufacturer's 
report requirements in Sec.  178.35(g).
Section 178.337-17
    This section prescribes the marking requirements applicable to MC 
331 cargo tank motor vehicles. Paragraph (a) of this section outlines 
general requirements for marking of MC 331 cargo tank motor vehicles. 
PHMSA received a request for a letter of interpretation to clarify the 
applicability of these markings in Sec.  178.337-17(a) (Ref. No. 04-
0206). The request pointed out an incorrect use of the term cargo tank 
as it applies to the requirement for specification plates found in 
paragraph (a), which states that:

    ``Each cargo tank certified after October 1, 2004 must have a 
corrosion-resistant metal name plate (ASME Plate) and specification 
plate permanently attached to the cargo tank by brazing, welding or 
other suitable means on the left side near the front, in a place 
accessible for inspection.''

    In response, we stated that an MC 331 cargo tank must have a metal 
name plate (also referred to as an ASME plate) permanently attached to 
the cargo tank. In addition, an MC 331 cargo tank motor vehicle 
certified after October 1, 2004, must have a specification plate that 
includes the information specified in Sec.  178.337-17(c). PHMSA is 
proposing to clarify Sec.  178.337-17(a) to eliminate confusion of the 
name plate and specification plate requirements.
Section 178.345-3
    This section prescribes general requirements for the structural 
integrity of specification cargo tanks. Paragraph (c)(1) of this 
section addresses stress in the cargo tank shell resulting from normal 
operating loadings. PHMSA published a final rule on October 2, 2013 
(Docket No. PHMSA-2013-0158 (HM-244F); 78 FR 60745; effective October 
1, 2013) intending to correct the formula presented in paragraph (c)(1) 
for the figure ``SS2'' to read ``SS\2\.'' This correction 
correctly adjusted the standard ``2'' in the term to be a superscript 
``\2\,'' but inadvertently adjusted the second ``S'' from a subscript 
``S'' to a standard ``S.'' This is incorrect and PHMSA is 
proposing to revise this portion of the formula in Sec.  178.345-
3(c)(1) to read ``SS\2\.''
Section 178.955
    This section prescribes the design and testing criteria for Large 
Packagings. Presently, if a manufacturer of a Large Packaging wishes to 
construct a Large Packaging that differs from a listed specification 
there is no Associate Administrator approval provision outlined in the 
HMR. However, the HMR allude to the need for an approval in the Large 
Packaging marking requirements in Sec.  178.910(a)(1)(ii). The HMR has 
approval provisions in Part 178 for manufacturers of both non-bulk 
packagings and IBCs when constructing packagings that differ from 
listed specifications. In this rulemaking, we are proposing to include 
provisions consistent with the non-bulk packaging and IBC approval 
provisions for Large Packagings in Sec.  178.955. Such Large Packagings 
must be shown to be equally effective, and testing methods used must be 
equivalent. This change will resolve the issue with Sec.  
178.910(a)(1)(ii) and would be consistent with the UN Model Regulations 
and the IMDG Code, which provide approval provisions for non-bulk 
packagings, IBCs, and Large Packagings.

Part 179

Section 179.13
    This section includes limitations on rail tank car capacity and 
gross weight. With certain exceptions, this section generally limits 
the gross weight on rail of tank cars to 263,000 pounds. This section 
has been revised numerous times over the last several years. In 2009, 
PHMSA added paragraph (b) to this section authorizing tank cars 
designed to transport poisonous-by-inhalation (PIH) materials and built 
with certain mandated safety improvements (tank cars meeting the 
specifications of Sec.  173.244(a)(2) or (3) or Sec.  173.314(c) or 
(d)) to have a gross weight on rail of up to 286,000 pounds provided 
any weight increase was not used to increase product capacity. 74 FR 
1770 (Jan. 13, 2009). Subsequently, in an effort to incorporate several 
widely used special permits providing relief from the gross weight 
limitations of Sec.  179.13, PHMSA revised the section to provide FRA 
the authority to approve the operation of tank cars containing 
materials other than PIH materials at gross weights of up to 286,000 
pounds. 75 FR 27205 (May 14, 2010). FRA published notice of its 
approvals under this section on January 25, 2011. 76 FR 4250.
    In 2011, noting that the agency's stated intent in the 2010 rule 
was to incorporate into the HMR existing special permits related to 
tank car gross weight for tank cars carrying both non-PIH materials and 
PIH materials by giving FRA authority to approve tank car weights up to 
286,000 pounds for both types of tank cars, PHMSA proposed to revise 
Sec.  179.13 to correct the omission of PIH material tank cars from 
FRA's approval authority. See 76 FR 51324, 51331. However, when adopted 
as a final rule, the regulatory language did not correct this 
inadvertent omission. See 77 FR 37962, 37985 (HM-218B) (June 25, 2012). 
Instead, in the final HM-218B rule, Sec.  179.13 was revised to provide 
that tank cars designed to transport PIH materials and built with the 
mandated safety improvements set forth in Sec.  173.244(a)(2) or (3) or 
Sec.  173.314(c) or (d)) ``may have a gross weight on rail of up to 
286,000 pounds upon approval by the Associate Administrator for 
Railroad Safety, FRA.'' As clearly demonstrated by the 2009 and 2010 
rules, it was not the intent of either PHMSA or FRA to require FRA 
approval of tank cars built to the enhanced standards of Sec.  
173.244(a)(2) or (3) or Sec.  173.314(c) or (d) for those cars to 
operate at a gross rail load of 286,000 pounds. Accordingly, in this 
rule PHMSA is proposing to revise Sec.  179.13 to correct this error 
and (1) make it clear that tank cars built to the enhanced standards of 
Sec.  173.244(a)(2) or (3) or Sec.  173.314(c) or (d) do not need FRA 
approval to operate at gross rail loads of up to 286,000 pounds; and 
(2) to provide for FRA approval of tank cars containing PIH materials 
that do not meet the enhanced standards to operate at gross rail loads 
of up to 286,000 pounds.

Part 180

Section 180.209
    This section prescribes requalification requirements for DOT 
specification cylinders. Paragraph (j) contains a reference to an 
obsolete special provision. In a January 7, 2013 final rule (78 FR 
1101), we removed and relocated

[[Page 3803]]

regulatory text from Sec.  172.102(c)(1) Special Provision 18 to Sec.  
173.309(a), which prescribes the conditions when specification 
cylinders may be described, offered, and transported in commerce as 
fire extinguishers. In relocating the text, we did not update this 
section to reflect the change. In this rulemaking, we are proposing to 
correct this inconsistency by replacing the reference to Sec.  
172.102(c)(1) Special Provision 18 with Sec.  173.309(a).
Section 180.401
    This section provides the applicability of the requirements of 
Subpart E of Part 180. It states that Subpart E prescribes 
requirements, in addition to those contained in Parts 107, 171, 172, 
173 and 178 of this subchapter, applicable to any person responsible 
for the continuing qualification, maintenance or periodic testing of a 
cargo tank.
    The term ``person,'' as defined in Sec.  171.8, means an 
individual, corporation, company, association, firm, partnership, 
society, joint stock company; or a government, Indian tribe, or 
authority of a government or tribe offering a hazardous material for 
transportation in commerce or transporting a hazardous material to 
support a commercial enterprise. This term does not include the United 
States Postal Service or, for purposes of 49 U.S.C. 5123 and 5124, a 
Department, agency, or instrumentality of the government.
    The intent of Sec.  180.401 is to require a person involved with 
continuing qualification, maintenance or periodic testing of a cargo 
tank to comply with the requirements of Subpart E, even if they are not 
offering a hazardous material for transportation in commerce or 
transporting a hazardous material to support a commercial enterprise. 
In this rulemaking, we are proposing to revise the term ``person'' to 
``hazardous materials employee or hazardous materials employer.'' This 
will clarify that Subpart E of Part 180 not only applies to persons 
offering hazardous materials for transportation or transporting a 
hazardous material, but also those involved with qualification, 
maintenance or periodic testing.

V. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This NPRM 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 hazardous materials law authorizes 
the Secretary of Transportation to prescribe regulations for the safe 
transportation, including security, of hazardous materials in 
intrastate, interstate, and foreign commerce. If adopted as proposed, 
this NPRM would make miscellaneous amendments to the HMR, correct 
errors in the Sec.  172.101 HMT and corresponding special provisions, 
and respond to NTSB Safety Recommendations related to the safe 
transportation of manifolded acetylene cylinders.
    Additionally, this NPRM will respond to petitions for rulemaking 
related to the allowable format for emergency telephone numbers on 
shipping papers, relax the pressure test interval for certain cargo 
tanks in dedicated propane service, enhance the safe packaging for 
nitric acid, clarify the testing requirements for specification cargo 
tank pressure relief devices, harmonize the hazard communication 
requirements for poisonous by inhalation materials transported by 
vessel and eliminate a potentially confusing packing group designation 
for certain organic peroxides, self-reactive materials and explosives. 
These amendments clarify regulatory requirements and, where 
appropriate, decrease the regulatory burden without compromising the 
safe transportation of hazardous materials in commerce.

B. Executive Order 12866, Executive Order 13563 and DOT Regulatory 
Policies and Procedures

    This proposed rule is not considered a significant regulatory 
action under section 3(f) and was not reviewed by the Office of 
Management and Budget (OMB). The proposed rule is not considered a 
significant rule under the Regulatory Policies and Procedures order 
issued by the Department of Transportation [44 FR 11034].
    In this notice of proposed rulemaking, we propose to amend 
miscellaneous provisions in the HMR to clarify the provisions and to 
relax overly burdensome requirements. PHMSA anticipates the proposals 
contained in this rule will have economic benefits to the regulated 
community. This NPRM is designed to increase the clarity of the HMR, 
thereby increasing voluntary compliance while reducing compliance 
costs.
    Executive Order 13563 is supplemental to and reaffirms the 
principles, structures, and definitions governing regulatory review 
that were established in Executive Order 12866 Regulatory Planning and 
Review of September 30, 1993. In addition, Executive Order 13563 
specifically requires agencies to: (1) Involve the public in the 
regulatory process; (2) promote simplification and harmonization 
through interagency coordination; (3) identify and consider regulatory 
approaches that reduce burden and maintain flexibility; (4) ensure the 
objectivity of any scientific or technological information used to 
support regulatory action; and (5) consider how to best promote 
retrospective analysis to modify, streamline, expand, or repeal 
existing rules that are outmoded, ineffective, insufficient, or 
excessively burdensome.
    In this NPRM, PHMSA has involved the public in the regulatory 
process in a variety of ways. Specifically, PHMSA is addressing issues 
and errors that were identified for future rulemaking in letters of 
interpretation and through other correspondence with PHMSA stakeholders 
who bring editorial errors in the HMR to our attention. In addition, 
PHMSA has responded to seven petitions for rulemaking and two NTSB 
Safety Recommendations. PHMSA is asking for public comments based on 
the proposals in this NPRM. Upon receipt of public comment, PHMSA will 
address all substantive comments in the next rulemaking action under 
this docket number.
    The proposed amendments in the NPRM promote simplification and 
harmonization through interagency coordination. In this NPRM, PHMSA is 
proposing to revise 49 CFR part 175, in a collaborative effort with the 
Federal Aviation Administration (FAA), to clarify the applicability of 
the HMR to certain aircraft operators, clarify exceptions for 
passengers and crewmembers, correct inaccurate references to the 14 
CFR, as well as make minor editorial corrections applicable to air 
operations to improve overall clarity. There are minimal additional 
costs associated with these proposals, however increased clarity will 
result in net benefits. Additionally, by updating references to the AAR 
Tank Car Manual in Sec.  171.7, PHMSA worked collaboratively with FRA, 
promoting interagency coordination.
    This NPRM also promotes harmonization with international standards, 
such as the IMDG Code, Canada's TDG requirements and the ICAO TI. These 
efforts include:
     Harmonizing hazard communication for poisonous-by-
inhalation materials with the IMDG Code and TDG regulations;
     Removing the packing group II designation for certain 
organic peroxides, self-reactive substances and explosives to be 
consistent with the UN Recommendations, IMDG Code and

[[Page 3804]]

ICAO TI and thus, facilitate international transport;
     Harmonizing entries in the HMT with the above listed 
international standards;
     Revising the passenger exceptions applicable to small 
cartridges containing Division 2.2 gas with the ICAO TI; and
     Harmonizing the excepted quantities requirements to mirror 
language employed in the ICAO TI as they apply to articles.
    These revisions to the Sec.  172.101 HMT will eliminate errors in 
the Sec.  172.101 HMT, reduce ambiguity, harmonize the HMR with 
international regulations, and improve clarity. Although these 
revisions are minor, they are expected to produce a safety benefit 
derived from the increased clarity and accuracy of the text in the 
Sec.  172.101 HMT.
    This NPRM permits flexibility in achieving compliance when 
transporting damaged wet electric storage batteries. This NPRM also 
extends the requalification interval for certain MC 331 cargo tanks in 
dedicated propane service from five years to ten years for a pressure 
test and internal visual inspection, therefore, fostering greater 
regulatory flexibility without compromising transportation safety. 
PHMSA is also clarifying the regulations to provide flexibility in the 
ability to use the NOT-ODORIZED or NON-ODORIZED marking on cargo tanks, 
cylinders and portable tanks containing odorized or unodorized LPG. 
Additionally, by allowing 100 pounds of black or smokeless powder for 
small arms reclassed as Division 4.1 in each transport vehicle, instead 
of each motor vehicle, the regulated community can reduce the number of 
motor vehicles needed to transport these goods.
    Where PHMSA identified potential costs to stakeholders, specific 
comment was requested to clarify such costs. We request specific 
comment on potential cost impacts of the proposals in Sec.  172.604 and 
Sec.  173.158(e).
    A majority of the amendments in this rulemaking are simple 
clarifications and do not require significant scientific or 
technological information. However, when necessary in this NPRM, PHMSA 
used scientific or technological information to support its regulatory 
action. Specifically, such data was considered when structuring 
alternatives on how to best deal with issues regarding the testing of 
pressure relief devices for cargo tank motor vehicles and extending the 
pressure test and internal visual inspection test interval from five to 
ten years for certain MC 331 cargo tanks in dedicated propane delivery 
service. This information was used in the evaluation of alternative 
proposals and ultimately this information determined how best to 
promote retrospective analysis to modify and streamline existing 
requirements that are outmoded, ineffective, insufficient, or 
excessively burdensome.

C. Executive Order 13132

    This proposed rule was analyzed in accordance with the principles 
and criteria contained in Executive Order 13132 (``Federalism''). This 
proposed rule would preempt state, local and Indian tribe requirements 
but does not propose 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.
    The 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. 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 
related to hazardous materials and requirements related to the number, 
content, and placement of those documents;
    (iv) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous materials; or
    (v) 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 materials.
    This proposed rule concerns the classification, packaging, and 
handling of hazardous materials, among other covered subjects. If 
adopted, this rule would preempt 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. 
PHMSA proposes the effective date of federal preemption be 90 days from 
publication of a final rule in this matter in the Federal Register.

D. Executive Order 13175

    This proposed 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 proposed rule does not have tribal implications and does 
not impose substantial direct compliance costs on Indian tribal 
governments, the funding and consultation requirements of Executive 
Order 13175 do not apply, and a tribal summary impact statement is not 
required.

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 
unless the agency determines the rule is not expected to have a 
significant impact on a substantial number of small entities. This 
proposed rule would clarify provisions based on PHMSA's initiatives and 
correspondence with the regulated community. The proposed changes are 
generally intended to provide relief to shippers, carriers, and 
packaging manufacturers, including small entities, by easing overly 
burdensome requirements with no reduction in safety.
    Consideration of alternative proposals for small businesses. The 
Regulatory Flexibility Act directs agencies to establish exceptions and 
differing compliance standards for small businesses, where it is 
possible to do so and still meet the objectives of applicable 
regulatory statutes. In the case of hazardous materials transportation, 
it is not possible to establish exceptions or differing standards and 
still accomplish our safety objectives.
    The impact of this proposed rule is not expected to be significant. 
The proposed changes are generally intended to provide relief to 
shippers, carriers, and packaging manufactures and testers, including 
small entities. This relief will provide marginal positive economic 
benefits to shippers, carriers, and packaging manufactures and testers, 
including small entities. These benefits are not at a level that can be 
considered economically significant;

[[Page 3805]]

therefore, this proposed rule will not have a significant economic 
impact on a substantial number of small entities.
    This proposed 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.

F. Paperwork Reduction Act

    PHMSA currently has an approved information collection under Office 
of Management and Budget (OMB) Control Number 2137-0557, entitled 
``Approvals for Hazardous Materials.'' This proposed rule does not 
propose any changes that would affect the burden for this or any other 
information collection.
    Prior to the publication of a final rule entitled ``Hazardous 
Materials: Revisions to Fireworks Regulation'' under Docket No. PHMSA-
2010-0320 (HM-257) published in the Federal Register on July, 6 2013 
[78 FR 42457], the HMR contained a requirement that all certification 
agencies provide a statement that it would perform its functions 
independent of the owners and manufacturers of the packagings in its 
field. The burden for this requirement was accounted for under OMB 
Control Number 2137-0557. However, the HM-257 final rule inadvertently 
removed this language from the HMR. Therefore, in this NPRM, PHMSA is 
proposing to reinsert the language for certification agencies to 
confirm that they are independent and not owned by a company in its 
field. For ease of the reader, this language is being proposed to be 
inserted as follows:
     PHMSA is proposing to revise Sec.  107.402(f) to require 
that a portable tank and MEGC certification agency submit a statement 
indicating that the agency is independent of and not owned by a 
portable tank or MEGC manufacturer, owner, or distributor as part of 
the Portable tank and MECG Certification Agency application.
     PHMSA is proposing to revise Sec.  107.402(e) to require 
that a lighter certification agency submit a statement that the agency 
is independent of and not owned by a lighter manufacturer, distributor, 
import or export company, or proprietorship as part of the Lighter 
Certification Agency application.
     PHMSA is proposing to revise Sec.  107.807 to require that 
person who seeks to manufacture DOT specification cylinders and special 
permit cylinders, or perform chemical analysis and tests of those 
cylinders outside the United States submits a statement, as part of the 
application, indicating that the inspection agency is independent of 
and not owned by a cylinder manufacturer, owner, or distributor.

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 proposed rule does not impose unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. It does not result in costs of 
$141,300,000 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 objective of the rule.

I. Environmental Assessment

    The National Environmental Policy Act of 1969, 42 U.S.C. 4321-4375, 
requires that federal agencies analyze proposed actions to determine 
whether the action will have a significant impact on the human 
environment. The Council on Environmental Quality (CEQ) regulations 
require federal agencies to conduct an environmental review considering 
(1) the need for the proposed action, (2) alternatives to the proposed 
action, (3) probable environmental impacts of the proposed action and 
alternatives, and (4) the agencies and persons consulted during the 
consideration process (40 CFR 1508.9(b)).
    This NPRM would amend the Hazardous Materials Regulations (HMR; 49 
CFR parts 171-180) by making miscellaneous revisions to update and 
clarify certain regulatory requirements, responds to seven petitions 
for rulemaking submitted to PHMSA by various stakeholders, and 
addresses two NTSB recommendations. These amendments are intended to 
promote safety, regulatory relief, and clarity. The proposed changes 
were identified through an internal review of the HMR as well as in 
response to communications with various stakeholders affected by the 
HMR, through letters of interpretation and editorial issues being 
brought to our attention. These proposed minor changes will clarify the 
HMR and enhance safety, while offering net economic benefits.
    This action is necessary to: (1) Fulfill our statutory directive to 
promote transportation safety; (2) fulfill our statutory directive 
under the Administrative Procedure Act (APA) that requires Federal 
agencies to give interested persons the right to petition an agency to 
issue, amend, or repeal a rule (5 U.S.C. 553(e)); (3) support 
governmental efforts to provide regulatory relief to the regulated 
community; (4) address safety concerns raised by the NTSB and remove 
regulatory ambiguity identified by the regulated community; and (5) 
simplify and clarify the regulations in order to promote understanding 
and compliance.
    The intended effect of this action is to enhance the safe 
transportation of hazardous materials and, in conjunction, clarify, 
simplify and relax certain regulatory requirements for carriers, 
shippers, and other stakeholders. These regulatory revisions will offer 
more efficient and effective ways of achieving safe and secure 
transportation of hazardous materials in commerce.
Description of Action: Docket No. PHMSA-2013-0225 (HM-218H), NPRM
    Transportation of hazardous materials in commerce is subject to 
requirements in the HMR, issued under authority of Federal hazardous 
materials transportation law, codified at 49 U.S.C. 5001 et seq. To 
facilitate the safe and efficient transportation of hazardous materials 
in international commerce, the HMR provide that both domestic and 
international shipments of hazardous materials may be offered for 
transportation and transported under provisions of the international 
regulations.
    In proposing this rulemaking, PHMSA is considering the following 
alternatives:
Alternative 1: No Action
    If PHMSA chose this alternative, it would not proceed with any 
rulemaking on this subject and the current regulatory standards would 
remain in effect. This option would not address outstanding petitions 
for rulemaking or NTSB Safety Recommendations. We rejected the no 
action alternative.
Alternative 2: Go Forward With the Proposed Amendments to the HMR in 
This NPRM
    This alternative is the current proposal as it appears in this 
NPRM, applying to transportation of hazardous materials by various 
modes (highway, rail, vessel and aircraft). The proposed amendments 
encompassed in this alternative are more fully addressed in

[[Page 3806]]

the preamble and regulatory text sections. However, they generally 
include the following changes to the HMR, grouped below for ease of 
discussion:
    Incorporation by Reference and Use of International Standards:
     Remove the entry for CGA Publication C-1.1 in Table 1 to 
Sec.  171.7.
     Incorporate by reference in Sec.  171.7 CGA Publication G-
1.6, Standard for Mobile Acetylene Trailer Systems, Seventh Edition 
(responds to petition P-1605 and two NTSB Safety Recommendations, H-09-
01 and H-09-02).
     Incorporate by reference in Sec.  171.7 AAR Manual of 
Standards and Recommended Practices, Section C-III, Specifications for 
Tank Cars, Specification M-1002 (AAR Specifications for Tank Cars).
     Amend the marking requirements for poisonous by inhalation 
shipments transported in accordance with the IMDG Code or TDG 
Regulations (responds to petition for rulemaking P-1591).
    Sec.  172.101 Hazardous Materials Table and Sec.  172.102 Special 
Provisions:
     Remove the packing group II designation for certain 
organic peroxides, self-reactive substances and explosives (responds to 
petition for rulemaking P-1590).
     Revise the Sec.  172.101 table to add Special Provision 
B120 to column 7 for the entry ``Calcium nitrate, UN1454.''
     Revise the entry for ``Propellant, solid, UN0501'' to 
remove vessel stowage provision 24E from column 10B of the HMT.
     Revise the packing group II HMT entry for UN 2920, 
Corrosive liquids, flammable, n.o.s., to harmonize the HMR with the UN 
Model Regulations, IMDG Code and the ICAO TI by adding a reference to 
Sec.  173.154 to column 8A of the HMT.
     Revise the entry for ``Oxidizing solid, corrosive, n.o.s., 
UN 3085, PG II'' to harmonize the HMR with the UN Model Regulations, 
the IMDG Code and the ICAO TI by adding a reference to Sec.  173.152 to 
column 8A of the HMT.
     Revise the HMT entries for ``Trinitrophenol (picric acid), 
wetted, with not less than 10 percent water by mass, UN 3364'' and 
``Trinitrophenol, wetted with not less than 30 percent water, by mass, 
UN 1344'' to harmonize the HMR with the UN Model Regulations, IMDG 
Code, and the ICAO TI to clarify that the 500 gram limit per package 
does not apply to UN 1344 but does apply to UN 3364.
     Revise Special Provision 136, for Dangerous goods in 
machinery or apparatus, in Sec.  172.102 to include reference to 
subpart G of part 173.
     Remove reference to obsolete Special Provision 18 for the 
HMT entry ``UN 1044, Fire extinguishers'' and in Sec.  180.209(j).
    Hazard Communication (Marking, Labeling, Placarding, Emergency 
Response):
     Correct a reference in Sec.  172.201 to exceptions for the 
requirement to provide an emergency response telephone number on a 
shipping paper.
     Revise Sec. Sec.  172.301(f), 172.326(d) and 172.328(e) to 
include the clarification that the NOT-ODORIZED or NON-ODORIZED marking 
may appear on packagings used for both unodorized and odorized LPG, and 
remove the effective date of October 1, 2006 if it appears these 
paragraphs, as the effective date has passed.
     Amend Sec.  172.406(d) by expressly authorizing the use of 
labels described in subpart E with a dotted or solid line outer border 
on a surface background of contrasting color.
     Amend the address in Sec.  172.407(d)(4)(ii) to read 
Standards and Rulemaking Division, Pipeline and Hazardous Materials 
Safety Administration, U.S. Department of Transportation, East 
Building, 1200 New Jersey Avenue SE., Washington, DC 20590-0001.
     Clarify the marking size requirements for an IBC that is 
labeled instead of placarded by replacing the bulk package marking 
reference in Sec.  172.514(c) with the non-bulk marking reference, 
Sec.  172.301(a)(1).
     Require that emergency response telephone numbers be 
displayed on shipping papers numerically (responds to petition for 
rulemaking P-1597).
    Shipper Requirements:
     Revise Sec.  173.4a(a) to clarify that articles (including 
aerosols) are not eligible for excepted quantity reclassification under 
Sec.  173.4a, although some are eligible to be shipped as small 
quantities by highway and rail in Sec.  173.4.
     Revise Sec.  173.21(e) to include the prohibition of 
transporting or offering for transport materials in the same transport 
vehicle (e.g. trailer, rail car) with another material, the mixing of 
which is likely to cause a dangerous evolution of heat, flammable or 
poisonous gases or vapors, or to produce corrosive materials.
     Clarify that the requirements provided in paragraph Sec.  
173.24a(c)(1)(iv) do not apply to limited quantities packaged in 
accordance with Sec.  173.27(f)(2).
     Clarify the quantity limits for mixed contents packages 
prepared in accordance with Sec.  173.27(f)(2).
     Clarify the requirements applicable to bulk transportation

    Probable Environmental Impacts of the Alternatives:
    Background: Hazardous materials are substances that may pose a 
threat to public safety or the environment during transportation 
because of their physical, chemical, or nuclear properties. The 
hazardous materials regulatory system is a risk management system that 
is prevention-oriented and focused on reducing the probability and 
quantity of a hazardous material release. Hazardous materials are 
categorized by hazard analysis and experience into hazard classes and 
packing groups. The regulations require each shipper to classify a 
material in accordance with these hazard classes and packing groups. 
The process of classifying a hazardous material is itself a form of 
hazard analysis. Further, the regulations require the shipper to 
communicate a material's hazards through use of the hazard class, 
packing group, and proper shipping name on the shipping paper and the 
use of labels on packages and placards on transport vehicles. Thus, the 
shipping paper, labels, and placards communicate the most significant 
findings of the shipper's hazard analysis. A hazardous material is 
assigned to one of three packing groups based upon its degree of 
hazard, from a high hazard, Packing Group I to a low hazard, Packing 
Group III material. The quality, damage resistance, and performance 
standards of the packaging in each packing group are appropriate for 
the hazards of the material transported.
    Under the HMR, hazardous materials are transported by aircraft, 
vessel, rail, and highway. The potential for environmental damage or 
contamination exists when packages of hazardous materials are involved 
in accidents or en route incidents resulting from cargo shifts, valve 
failures, package failures, loading, unloading, collisions, handling 
problems, or deliberate sabotage. The release of hazardous materials 
can cause the loss of ecological resources (e.g. wildlife habitats) and 
the contamination of air, aquatic environments, and soil. Contamination 
of soil can lead to the contamination of ground water. Compliance with 
the HMR substantially reduces the possibility of accidental release of 
hazardous materials.
    When developing potential regulatory requirements, PHMSA evaluates 
those requirements to consider the environmental impact of each 
amendment. Specifically, PHMSA evaluates the risk of release and 
resulting environmental impact, risk to human safety, including any 
risk to first responders, longevity of the packaging, and potential 
impact of a proposed regulation in a defined area. We have determined 
that most of the regulatory changes proposed in this rulemaking are 
editorial in nature. As such, these amendments have no impact on the 
risk of release and resulting environmental impact, human safety, 
longevity of the packaging, and none of these amendments would be 
carried out in a defined geographic area. General possible 
environmental benefits, and detriments, are discussed below.
Alternative 1: No Action
    If PHMSA were to select the No Action Alternative, current 
regulations would remain in place, and no new provisions would be 
added. However, this option would not address outstanding petitions for 
rulemaking, NTSB Safety Recommendations or consider amendments based on 
PHMSA's own initiatives intended to update, clarify, or provide relief 
from certain existing regulatory requirements. Foregone efficiencies in 
the No Action Alternative also include freeing up limited resources to 
concentrate on hazardous materials transportation issues of potentially 
much greater environmental impact.
    Additionally, the Preferred Alternative encompasses enhanced and 
clarified regulatory requirements, which would result in increased 
compliance and fewer environmental and safety incidents. Not adopting 
the proposed environmental and safety requirements in the NPRM under 
the No Action Alternative would result in a lost opportunity for 
reducing environmental and safety-related incidents.
    Greenhouse gas emissions would remain the same under the No Action 
Alternative.
Alternative 2: Go Forward With the Proposed Amendments to the HMR in 
This NPRM
    If PHMSA selects the provisions as proposed in this NPRM, we 
believe that safety and environmental risks would be reduced and that 
protections to human health and environmental resources would be 
increased.
    Enhanced environmental protection will also be achieved through 
more targeted and effective training. This proposed set of amendments 
will eliminate inconsistent hazardous materials regulations, which 
hamper compliance training efforts. By maintaining consistency between 
these international regulations and the HMR, shippers and carriers are 
able to train their hazardous materials employees in a single set of 
requirements for classification, packaging, hazard communication, 
handling, and stowage, thereby minimizing the possibility of improperly 
preparing and transporting a shipment of hazardous materials because of 
differences between domestic and international regulations. This 
proposed set of amendments will create more streamlined hazardous 
regulations, resulting in compliance training efforts which facilitate 
the regulated community's ability to comply with the HMR. Potential 
environmental impacts of each proposed group of amendments in 
Alternative 2 (selected for NPRM) are discussed individually below.
    Incorporation by Reference and Use of International Standards:
    PHMSA believes that this proposed set of amendments, which will 
increase standardization and consistency of regulations, will result in 
greater protection of human health and the environment. Consistency 
between US and international regulations enhances the safety and 
environmental protection of international hazardous materials 
transportation through better understanding of the regulations, an 
increased level of industry compliance, the smooth flow of hazardous 
materials from origin to destination, and consistent emergency response 
in the event of a hazardous materials incident. Incorporation of the 
CGA Publication G-1.6, Standard for Mobile Acetylene Trailer Systems, 
will mitigate acetylene release and enhance environmental protection 
during overturn incidents

[[Page 3808]]

and unloading. Incorporation of AAR Manual of Standards and Recommended 
Practices, Section C-III, Specifications for Tank Cars, Specification 
M-1002 (AAR Specifications for Tank Cars) and certain subsequent 
amendments will update the previously incorporated 2000 edition 
ensuring increased safety through compliance with revised tank car 
standards.
    Current greenhouse gas emissions would be unaffected under this 
proposed set of amendments.
    Section 172.101 Hazardous Materials Table and Sec.  172.102 Special 
Provisions:
    PHMSA believes that this proposed set of amendments, which will 
increase standardization and consistency of regulations, will result in 
greater protection of human health and the environment. Consistency 
between U.S. and international regulations enhances the safety and 
environmental protection of international hazardous materials 
transportation through better understanding of the regulations, an 
increased level of industry compliance, the smooth flow of hazardous 
materials from their points of origin to their points of destination, 
and consistent emergency response in the event of a hazardous materials 
incident. New and revised entries to the HMT reflect emerging 
technologies, and a need to better describe or differentiate between 
existing entries. These proposed changes mirror changes in the 
Dangerous Goods list of The 18th Revised Edition of the UN Model 
Regulations, the 2013-2014 ICAO TI and the 37-14 amendments to the IMDG 
Code. It is extremely important for the domestic HMR to mirror the UN 
Model Regulations, the ICAO TI, and the IMDG Code with respect to the 
entries in the HMT to ensure consistent naming conventions across modes 
and international borders.
    The packing group assignment reflects a degree of danger associated 
with a particular material and identifies appropriate packaging. 
However, assignment of a packing group is not appropriate in all cases 
(e.g. explosives, gases, radioactive material). In such cases the 
packing group does not indicate a degree of danger and the packaging 
requirements for those materials are specified in the appropriate 
section in part 173. The proposed change to eliminate a packing group 
designation for materials classified as explosives and organic 
peroxides specifically listed in the HMT provides a level of 
consistency, without diminishing environmental protection and safety.
    Current greenhouse gas emissions would be unaffected under this 
proposed set of amendments.
    Hazard Communication (Marking, Labeling, Placarding, Emergency 
Response):
    PHMSA believes that this proposed set of amendments, which will 
provide for enhanced hazard communication (hazcom), will result in 
greater protection of human health and the environment. The proposed 
changes communicate the nature of various specialized packaging 
configurations to package handlers and emergency responders. The 
proposed amendments would ensure that hazard markings are visible, 
universally recognizable, and that they contain all information needed 
by emergency responders, thus resulting in fewer incidents with impacts 
to the environment and safety.
    Similar to the above sets of amendments, PHMSA believes that this 
proposed set of amendments, which will increase standardization and 
consistency of regulations, will result in greater protection of human 
health and the environment. Consistency between U.S. and international 
regulations enhances the safety and environmental protection of 
international hazardous materials transportation through better 
understanding of the regulations, an increased level of industry 
compliance, the smooth flow of hazardous materials from their points of 
origin to their points of destination, and consistent emergency 
response in the event of a hazardous materials incident.
    Current greenhouse gas emissions would be unaffected under this 
proposed set of amendments.
    Shipper Requirements:
    PHMSA believes that this proposed amendment, which will revise, 
clarify and enhance current regulations, will result in greater 
protection of human health and the environment. Compliance with the HMR 
will be facilitated for shippers and transporters of hazardous 
materials through regulations which are easier to understand and more 
streamlined. Additionally, the revisions include emphasis being placed 
in areas requiring more attention.
    Specific to this set of amendments, improving the packaging 
requirements applicable to glass packages of nitric acid reduces the 
occurrences of fires caused by broken inner containers and enhances 
human health and environmental protection. PHMSA believes that the 
additional intermediate packaging required by this particular amendment 
will add another layer of protection in preventing breakage, leakage 
and fires. Additionally, this particular amendment creates a more 
streamlined and efficient HMR through incorporation of a petition for 
rulemaking, P-1601. A more streamlined and efficient HMR allows both 
regulators and the regulated community to target limited resources at 
the most pressing hazmat compliance issues.
    Current greenhouse gas emissions would be unaffected under this 
proposed set of amendments.
    Modal Requirements (Air, Vessel, and Highway):
    PHMSA believes that this proposed amendment, which will revise, 
clarify and enhance current regulations, will result in greater 
protection of human health and the environment. Compliance with the HMR 
will be facilitated for air, vessel and highway shippers and 
transporters of hazardous materials through regulations which are 
easier to understand and more streamlined. Additionally, the revisions 
include emphasis being placed in areas requiring more attention.
    Current greenhouse gas emissions would be unaffected under this 
proposed set of amendments.
    Packaging design and requalification:
    PHMSA believes that this proposed amendment, which will revise, 
clarify and enhance current regulations, will result in greater 
protection of human health and the environment. Compliance with the HMR 
will be facilitated for shippers and transporters of hazardous 
materials through regulations which are easier to understand and more 
streamlined. Additionally, the revisions include emphasis being placed 
in areas requiring more attention.
    Specific to this set of amendments, decreasing the required 
frequency for pressure testing and visual inspection of certain cargo 
tanks in dedicated propane service by extending the requalification 
period from five years to ten years will ease the burden on regulators 
and the regulated community. This test, which requires significant 
equipment down-time and man-hours to perform, has been shown to achieve 
no additional safety or environmental protection when performed at a 
five- versus a ten-year interval. Pressure testing requires a 
significant amount of water usage. Decreasing the testing frequency by 
half will result in significant volumes of water being conserved. 
Additionally, this particular amendment creates a more streamlined and 
efficient HMR through incorporation of a petition for rulemaking, P-
1609. A more streamlined and efficient HMR allows both regulators and 
the regulated community to target limited resources at

[[Page 3809]]

the most pressing hazmat compliance issues.
    Current greenhouse gas emissions would be unaffected under these 
amendments.
Agencies Consulted
    This NPRM would affect some PHMSA stakeholders, including hazardous 
materials shippers and carriers by highway, rail, vessel, and aircraft, 
as well as package manufacturers and testers. PHMSA is seeking comment 
on the environmental assessment contained in this NPRM. In addition, 
PHMSA specifically coordinated with the following Federal Agencies and 
modal partners:

 Department of Justice
 Environmental Protection Agency
 Health and Human Services
 Occupational Safety and Health Administration
 Federal Aviation Administration
 Federal Motor Carrier Safety Administration
 Federal Railroad Administration
 United States Coast Guard
Conclusion
    PHMSA proposes to make miscellaneous amendments to the HMR based on 
comments from the regulated community, NTSB recommendations, and 
PHMSA's own rulemaking initiatives. The proposed amendments are 
intended to update, clarify, or provide relief from certain existing 
regulatory requirements to promote safer transportation practices; 
eliminate unnecessary regulatory requirements; facilitate international 
commerce; and make these requirements easier to understand. These 
proposed clarifications of regulatory requirements, if adopted, will 
foster a greater level of compliance with the HMR and thus, diminished 
levels of hazardous materials transportation incidents affecting the 
health and safety of the environment. Therefore, the net environmental 
impact of this proposal will be positive.

K. International Trade Analysis

    The Trade Agreements Act of 1979 (Pub. L. 96-39), as amended by the 
Uruguay Round Agreements Act (Pub. L. 103-465), prohibits Federal 
agencies from establishing any standards or engaging in related 
activities that create unnecessary obstacles to the foreign commerce of 
the United States. Pursuant to these Acts, establishing standards is 
not considered an unnecessary obstacle to the foreign commerce of the 
United States, so long as the standards have a legitimate domestic 
objective, such as the protection of safety, and do not operate in a 
manner that excludes imports that meet this objective. The statute also 
requires consideration of international standards and, where 
appropriate, that they be the basis for U.S. standards. PHMSA notes the 
purpose is to ensure the safety of the American public, and has 
assessed the effects of this rule to ensure that it does not exclude 
imports that meet this objective. As a result, this proposed rule is 
not considered as creating an unnecessary obstacle to foreign commerce.
