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. 

A. Petitions for Rulemaking 

The following table provides a brief 

summary of the petitions addressed in 

this NPRM and affected sections. These 

petitions are included in the docket for 

this proceeding:

Petition Petitioner Summary 

P–1609 .... Truck Trailer Manufacturers Association (TTMA).Clarify the requirements applicable to the testing of pressure relief devices for cargo tank motor 

vehicles (§ 180.407). 

B. NTSB Safety Recommendations 

The following table provides a brief 

summary of the NTSB recommendations 

addressed in this NPRM and affected 

sections. These recommendations are 

included in the docket for this 

proceeding: 

Recommendation Summary 

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. 

C. Amendments Based on PHMSA 

Review 

In addition to addressing the petitions 

for rulemaking and the NTSB 

recommendations listed above, this 

rulemaking proposes the following 

amendments that were identified 

through our retrospective review of the 

49 CFR. We summarize the changes as 

follows: 

• Revise § 107.402(d)(2) to replace the 

term ‘‘citizen’’ with the term ‘‘resident.’’ 

• Revise § 107.402(e) to require that a 

lighter certification agency submits a 

statement that the agency is 

independent of and not owned by a 

lighter manufacturer, distributor, import 

or export company, or proprietorship. 

• Revise § 107.402(f) to require 

portable tank and multi-element gas 

container (MEGC) certification agencies 

to submit a statement indicating that the 

agency is independent of and not owned 

by a portable tank or MEGC 

manufacturer, owner, or distributor. 

• Revise § 107.807 to require a 

cylinder inspection agency to be 

independent of and not owned by a 

cylinder manufacturer, owner, or 

distributor. 

• Remove the entry for CGA 

Pamphlet C–1.1 in Table 1 to § 171.7. 

• Incorporate by reference updated 

versions of the American Association of 

Railroads (AAR) Manual of Standards 

and Recommended Practices, Section 

C–III, Specifications for Tank Cars, 

Specification M–1002 in § 171.7. 

• Revise the § 172.101 table to add 

Special Provision B120 to Column (7) 

for the entry ‘‘Calcium nitrate, 

UN1454.’’

solid, UN0501’’ to remove vessel 

stowage provision 24E from Column 

(10B) of the HMT. 

• Revise the PG II HMT entry for 

‘‘UN2920, Corrosive liquids, flammable, 

n.o.s.,’’ to for consistency with the UN 

Model Regulations, IMDG Code, and the 

ICAO TI such that this entry is eligible 

for the limited quantity exceptions. 

• Revise the PG II HMT entry for 

‘‘UN3085, Oxidizing solid, corrosive, 

n.o.s.’’ for consistency with the UN 

Model Regulations, IMDG Code and the 

ICAO TI such that this entry is eligible 

for the limited quantity exceptions. 

• Revise 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’’ 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 UN1344 but 

does apply to UN3364. 

• Revise Special Provision 136, 

assigned to the proper shipping name 

‘‘UN3363, Dangerous goods in 

machinery or apparatus,’’ in § 172.102 

to include reference to Subpart G of Part 

173. 

• Remove reference to obsolete 

Special Provision 18 for the HMT entry 

‘‘UN1044, Fire extinguishers’’ and in 

§ 180.209(j) and provide correct cross 

reference to § 173.309.

exceptions for the requirement to 

provide an emergency response 

telephone number on a shipping paper. 

• Revise §§ 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 liquefied petroleum gas 

(LPG), and remove the effective date of 

October 1, 2006 or ‘‘after September 30, 

2006,’’ if it appears in these paragraphs, 

as the effective date has passed. 

• Amend § 172.406(d) by clearly 

authorizing the use of labels described 

in Subpart E with a dotted or solid line 

outer border on a surface background of 

contrasting color. 

• Update a mailing address in 

§ 172.407(d)(4)(ii). 

• Clarify the marking size 

requirements for an intermediate bulk 

container (IBC) that is labeled instead of 

placarded by replacing the bulk package 

marking reference in § 172.514(c) with 

the non-bulk marking reference, 

specifically, § 172.301(a)(1). 

• Revise § 173.4a(a) to clarify that 

articles (including aerosols) are not 

eligible for excepted quantity 

reclassification under § 173.4a, although 

some are eligible to be shipped as small 

quantities by highway and rail in 

§ 173.4. 

• Revise § 173.21(e) to prohibit 

transportation or offering for 

transportation materials in the same 

transport vehicle (e.g., a trailer, a rail 

car) with another material, that could 

cause a dangerous evolution of heat, 

flammable or poisonous gases or vapors, 

or produce corrosive materials if mixed. 

• Clarify that the requirements 

provided in paragraph 

§ 173.24a(c)(1)(iv) do not apply to 

limited quantities packaged in 

accordance with § 173.27(f)(2).

to bulk transportation of combustible 

liquids by adding new subparagraph 

§ 173.150(f)(3)(xi) stating that the 

registration requirements in Subpart G 

of Part 107 are applicable and revising 

§§ 173.150(f)(3)(ix) and 173.150(f)(3)(x) 

for punctuation applicable to a listing of 

requirements. 

• Add a new paragraph (j) in 

§ 173.159 to allow shippers to prepare 

for transport and offer into

• Revise § 173.166(e)(6) to add the 

words ‘‘or cargo vessel.’’ 

• Revise §§ 173.170 and 173.171 by 

changing the term motor vehicle to 

transport vehicle to allow for motor 

vehicles comprised of more than one 

cargo-carrying body to carry 100 pounds 

of black or smokeless powder reclassed 

as Division 4.1 in each cargo-carrying 

body instead of 100 pounds total in the 

motor vehicle. 

• Revise § 173.199(a)(4) by removing 

the reference to the steel rod impact test 

in § 178.609(h). 

• Clarify the Packing Method table for 

organic peroxide materials in § 173.225. 

• Amend the bulk packaging section 

reference in Column (8C) of the HMT 

from § 173.240 to § 173.216 for the 

entries ‘‘Asbestos, NA2212,’’ ‘‘Blue

(amosite, mysorite) UN2212,’’ and 

‘‘White asbestos (chrysotile, actinolite, 

anthophyllite, tremolite), UN2590.’’ In 

addition, we are proposing to revise 

paragraph (c)(1) in § 173.216 by 

authorizing the use of bulk packages 

prescribed in § 173.240. 

• Add a new paragraph (d)(5) to 

§ 173.304a, a new paragraph (h) to 

§ 173.314 and revise § 173.315(b)(1) to 

require odorization of liquefied 

petroleum gas when contained in 

cylinders and rail cars. 

• Amend § 173.306(k) to clarify that 

aerosols shipped for recycling or

hazmat employer’’ to clarify that 

Subpart E of Part 180 does not only 

apply to persons offering or transporting 

hazardous materials. 

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 § 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, selfreactive 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 

§ 172.202(a)(4) requirement to include 

the ‘‘packing group in Roman numerals, 

as designated for the hazardous material 

in Column (5) of the § 172.101 table.’’ 

DGAC notes that while § 172.202(a)(4) 

also excepts organic peroxides, selfreactive 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 

§ 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.

Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 3791 

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 §§ 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 § 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 

§ 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 § 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 § 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 § 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 §§ 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 § 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 

§ 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 § 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 § 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 

§§ 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 

§ 172.604(a). DGAC states that 

historically telephone faces associated 

integers with letters (e.g., 2ABC), 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 § 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 § 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

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 

§ 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 § 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 § 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, nonreactive 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 § 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: nonquenched and tempered (NQT) SA–612 

steel and NQT SA–202 or SA–455 

steels, provided the materials have fullsize equivalent (FSE) Charpy-V notch 

energy test data that demonstrates 75% 

shear-area ductility at 32 °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 

§ 180.407(c) for certain MC 331 

Specification cargo tanks from a fiveyear 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 § 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 

§ 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 §§ 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 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 

§ 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 (§ 180.407(d)(3)) and the same 

10% allowance for DOT 400 series cargo 

tanks (§ 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 §§ 180.407(d)(3) and 

180.407(g)(1)(ii) with a reference to a 

new paragraph, § 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 §§ 180.407(d)(3) and 

180.407(g)(1) to reference a new section 

§ 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 

§ 107.402(d)(1)(i) to indicate that a 

fireworks certification agency applicant 

must be a U.S. resident, or for a nonU.S. resident, must have a designated 

U.S. agent representative as specified in 

§ 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 § 107.402(d)(1)(i) to 

correspond with the requirements of 

§ 105.40, which specifies designated 

agents for non-residents; however, the 

term ‘‘citizen’’ was inadvertently 

substituted for ‘‘resident.’’ PHMSA is 

proposing to revise § 107.402(d)(1)(i) by 

replacing the term ‘‘citizen’’ with the 

term ‘‘resident.’’ 

PHMSA is also proposing to revise 

§ 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 § 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 § 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 § 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 

§ 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
3794 Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 

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 §§ 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 § 180.205(g)(6) 

and inadvertently failed to remove the 

reference in § 171.7. PHMSA is 

proposing to amend Table 1 to § 171.7 

to remove the entry for CGA C–1.1 to 

align the regulatory text with previous 

rulemaking actions. 

Additionally, § 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 § 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 § 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 § 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 § 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-bySection review for § 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 § 171.12(a) to 

§ 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 § 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 

§ 172.101 HMT, including the special 

provisions listed in Column (7) of the 

table and specified in § 172.102, to 

clarify the regulations and correct 

inadvertent errors. Proposed changes to 

the § 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 3795 

§ 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 § 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 § 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 § 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 

§ 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 

§ 172.604(c), a shipping paper must 

contain an emergency response 

telephone number. The reference in this 

paragraph to § 172.604(c) is inaccurate. 

The requirements in § 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 

§ 172.201(d) to accurately reference the 

exception from the emergency response 

telephone number requirement found in 

§ 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 

(§§ 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 NOTODORIZED. PHMSA received a request 

for a letter of interpretation (Ref. No. 

06–0235) requesting clarification that 

the NON-ODORIZED or NOTODORIZED 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 NONODORIZED 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
3796 Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 

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 §§ 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 

§ 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, § 172.407(b)(2) provides that 

the dotted line border on each label 

shown in §§ 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 § 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 § 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 

§ 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 

§ 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 § 172.301(a)(1). 

In addition, the reference to the bulk 

packaging marking requirements of 

§ 172.302(b)(2) in § 172.514(c)(4) 

conflicts with § 172.336(d) 

identification number marking 

requirements which states ‘‘[w]hen a 

bulk packaging is labeled instead of 

placarded in accordance with 

§ 172.514(c) of this subchapter, 

identification number markings may be 

displayed on the package in accordance 

with the marking requirements of 

§ 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 

§ 172.514(c) with the non-bulk marking 

reference, specifically, § 172.301(a)(1). 

The reduced minimum marking size 

will alleviate the existing discrepancy 

between § 172.514(c)(4) and 

§ 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 § 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 § 173.4a, although 

some aerosols are eligible to be shipped 

as small quantities by highway and rail 

in § 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 § 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 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 § 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 

§ 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 § 173.21, 

there is no prohibition against this 

transport scenario. 

The concern is that a single cargocarrying 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 § 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 § 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 § 173.27(f)(2). This 

change is proposed for clarification 

purposes only. Misapplication of 

§ 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 § 173.27(f)(3), or the 

general provisions in § 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 

§ 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 § 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 § 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 

§§ 173.150(f)(3). Although placarding 

under Subpart F of Part 172 is specified 

as a requirement in § 173.150(f)(3)(iv), 

registration requirements of § 107.601 

are not included among the subject 

requirements. Given that § 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 

§ 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 §§ 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 § 173.159(e). In 

response, we stated that a damaged 

battery may be shipped in accordance 

with § 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 

§ 173.3(c). 

PHMSA is proposing to create a new 

paragraph (j) in § 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
3798 Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 

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 § 173.159. 

Section 173.166 

This section prescribes requirements 

applicable to the transportation of air 

bag inflators, air bag modules, and seatbelt 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 § 173.166, paragraph (e)(6) 

authorizes packaging alternatives for air 

bag inflators, air bag modules, and seatbelt 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 § 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 § 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 § 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 §§ 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 § 178.609(d) and the steel rod 

impact test in § 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 § 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 § 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 § 173.199(a)(4) 

by removing the reference to the steel 

rod impact test in § 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 § 173.216 

should apply to both ‘‘bulk’’ and ‘‘nonbulk’’ packages of asbestos, because as 

the requester noted in the letter, in the 

§ 172.101 HMT, the entry for 

‘‘Asbestos,’’ NA2212 refers to packaging 

instructions specified in § 173.216 for 

non-bulk packaging requirements, and 

§ 173.240 for bulk packaging 

requirements. It was also noted in the 

letter that some of the packaging options 

specified in § 173.216 are considered 

bulk packagings. 

PHMSA acknowledged that some of 

the packaging options provided in 

§ 173.216(c) meet the bulk packaging 

definition specified in § 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 § 173.216 by authorizing the use of 

bulk packages prescribed in § 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 § 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 

§ 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

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: 

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 § 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 

§ 171.7, and revise § 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 § 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 

§ 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 

§ 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 underodorization 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 onsite 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.

3800 Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 

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 endusers. 

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 §§ 173.304a(d)(5) 

and 173.314(h) consistent with the 

revised text in § 173.315(b)(1) to address 

the odorization of LPG in cylinders and 

rail tank car tanks, respectively. We are 

also proposing to revise § 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 § 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 § 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 §§ 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 § 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 

§ 173.306(k), are afforded the applicable 

exceptions provided for ORM–D 

materials granted under §§ 173.306(i) 

and 173.156(b). The letter provides that, 

consistent with § 173.306(i), packages 

containing aerosols meeting the limited 

quantity requirements of § 173.306(k) 

must be marked in accordance with 

§ 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 § 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 

§ 175.9(b). Paragraph (b)(4) of § 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 § 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 

§ 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 

§ 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 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, § 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 §§ 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 carryon 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 butanepowered 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 § 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 § 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 § 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 §§ 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 § 177.848(d). Presently, under 

§ 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, § 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 §§ 177.835(c)(1) through (4), 

regardless of the note ‘‘A’’ exception for 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
3802 Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 

UN1942 in § 177.848(e)(5). In this 

rulemaking, we are proposing to clarify 

that the loading restrictions in 

§ 177.835(c)(1) through (4) are 

applicable to § 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 § 178.35(h) 

in § 178.65(i)(1) is incorrect, as 

§ 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 § 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 § 178.65(i)(1) to 

correctly reference the manufacturer’s 

report requirements in § 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 § 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 

§ 178.337–17(c). PHMSA is proposing to 

clarify § 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 ‘‘SS2.’’ 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 

§ 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 § 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 § 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 § 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-byinhalation (PIH) materials and built 

with certain mandated safety 

improvements (tank cars meeting the 

specifications of § 173.244(a)(2) or (3) or 

§ 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 

§ 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 nonPIH 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 § 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, § 179.13 was 

revised to provide that tank cars 

designed to transport PIH materials and 

built with the mandated safety 

improvements set forth in 

§ 173.244(a)(2) or (3) or § 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 

§ 173.244(a)(2) or (3) or § 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 § 179.13 to correct 

this error and (1) make it clear that tank 

cars built to the enhanced standards of 

§ 173.244(a)(2) or (3) or § 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 3803 

regulatory text from § 172.102(c)(1) 

Special Provision 18 to § 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 § 172.102(c)(1) Special 

Provision 18 with § 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 

§ 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 § 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 § 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 § 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-byinhalation 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
3804 Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 

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 § 172.101 HMT 

will eliminate errors in the § 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 § 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 NONODORIZED 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 

§ 172.604 and § 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; 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 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 

§ 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 

§ 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 

§ 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

173.150(f)(3)(x) for punctuation 

applicable to a listing of requirements. 

• Require that certain shipments of 

nitric acid utilizing glass inner 

packagings be contained in intermediate 

packaging (responds to petition for 

rulemaking P–1601). 

• Add a new paragraph (j) in 

§ 173.159 to address the need for 

provisions that allow shippers to 

prepare for transport and offer into 

transportation damaged wet electric 

storage batteries. 

• Revise § 173.166(e)(6) to add the 

words ‘‘or cargo vessel.’’ 

• Revise §§ 173.170 and 173.171 by

transport vehicle to allow for motor 

vehicles comprised of more than one 

cargo-carrying body to carry 100 pounds 

of black or smokeless powder reclassed 

as Division 4.1 in each cargo-carrying 

body instead of 100 lbs total in the 

motor vehicle. 

• Revise the provisions in 

§ 173.199(a)(4) by removing the 

reference to the steel rod impact test in 

§ 178.609(h). 

• Amend the bulk packaging section 

reference in Column (8C) of the HMT 

from § 173.240 to § 173.216 for the

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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
3808 Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 

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 § 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 downtime and man-hours to perform, has 

been shown to achieve no additional 

safety or environmental protection 

when performed at a five- versus a tenyear 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 


tkelley on DSK3SPTVN1PROD with PROPOSALS3
Federal Register / Vol. 80, No. 15 / Friday, January 23, 2015 / Proposed Rules 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.
