I. Background

    In consultation with the Federal Aviation Administration (FAA), 
PHMSA (also ``we'' or ``us'') proposes to amend the Hazardous Materials 
Regulations (HMR; 49 CFR parts 171-180) to more closely align with 
certain provisions of the International Civil Aviation Organization's 
Technical Instructions for the Safe Transport of Dangerous Goods (ICAO 
TI). This NPRM also responds to four petitions for rulemaking submitted 
by the regulated community. The intended effect of these amendments is 
to update miscellaneous regulatory requirements for hazardous materials 
offered for transportation, or transported, in commerce by aircraft. 
The petitions are included in the docket for this proceeding and are 
discussed at length in Section II (``Overview of Proposals in this 
NPRM'') of this rulemaking.

[[Page 87511]]

II. Overview of Proposals in This NPRM

A. Transportation by Air Intermediate Packaging Requirements for 
Certain Low and Medium Danger Hazardous Materials (P-1637)

    The Dangerous Goods Advisory Council petitioned PHMSA to remove the 
additional intermediate packaging requirements found in special 
provisions A3 and A6, see 49 CFR 172.102(b)(2), by deleting these 
special provisions and all references to them in the Hazardous 
Materials Table (HMT) in Sec.  172.101. See P-1637.\1\ Special 
provisions A3 and A6 apply to certain commodities as assigned in column 
(7) of the HMT when transported by aircraft:
---------------------------------------------------------------------------

    \1\ https://www.regulations.gov/docket?D=PHMSA-2014-0094.
---------------------------------------------------------------------------

     Special provision A3 states that if glass inner packagings 
are used for transportation of referenced commodities, they must be 
packed with absorbent material in tightly closed metal receptacles 
before being packed in outer packagings.
     Special provision A6 states that if plastic inner 
packagings are used for transportation of referenced commodities, they 
must be packed in tightly closed metal receptacles before being packed 
in outer packagings.
    The petitioner notes that the packaging requirements imposed by 
special provisions A3 and A6 are domestic provisions not found in the 
ICAO TI and that maintaining these differences creates both a trade 
barrier to U.S. exports and a burden to the domestic market. The 
petitioner contends that the requirement for ``metal receptacles'' is 
overly restrictive and provides a competitive advantage to shippers in 
countries that allow these products to be shipped without additional 
intermediate packagings.

The petitioner further notes that the following requirements in Sec.  
173.27(d) and (e) of the HMR make special provisions A3 and A6 
unnecessary: (1) When transported by air, inner packagings of Packing 
Group (PG) I materials currently assigned A3, A6, or both are already 
required to be packed in either a rigid and leakproof receptacle or an 
intermediate packaging containing sufficient absorbent material to 
absorb the entire contents of the inner packaging before packing the 
inner packaging in its outer package; and (2) PG II and III commodities 
are already subject to secondary closure requirements. Therefore, the 
petitioner asks that the intermediate packaging requirements in special 
provisions A3 and A6 be removed.
    Section 173.27(d) establishes the type of closure required for 
transportation of liquid hazardous materials by air. It states that the 
inner packaging for PG I liquid hazardous materials must have a 
secondary means of closure applied. The inner packaging for PG II or PG 
III liquid hazardous materials must have a secondary closure applied 
unless the secondary closure is impracticable. If the secondary closure 
is impracticable, the closure requirements for PG II and PG III liquids 
may be satisfied by securely closing the inner packaging and placing it 
in a leakproof liner or bag before placing the inner packaging in the 
outer packaging.
    Section 173.27(e) sets the absorbency requirements for PG I liquid 
hazardous materials of Classes 3, 4, or 8, or Divisions 5.1 or 6.1, 
when the materials are packaged in glass, earthenware, plastic, or 
metal inner packagings and offered or transport by air. It requires 
that inner packagings be packed in a rigid and leakproof receptacle or 
intermediate packaging that that is sufficiently absorbent to absorb 
the entire contents of the inner packaging before the inner package is 
packed in the outer package.
    After reviewing the petition, PHMSA agrees that current 
requirements in Sec.  173.27(d) and (e) make special provisions A3 and 
A6 redundant for liquid PG I materials. We also agree that the 
requirements in Sec.  173.27(d) for inner packagings to have a 
secondary means of closure or a leakproof liner or bag adequately 
address the hazards that special provision A6 was designed to mitigate 
for PG II and III materials. However, we maintain that the material of 
construction of the inner packaging referenced in special provision A3 
(glass) necessitates an intermediate package to perform a containment 
function in the event an inner packaging breaks.
    Therefore, we propose to: (1) Amend special provision A3 in Sec.  
172.102 to authorize rigid and leakproof receptacles for intermediate 
packaging; (2) remove references to special provision A3 from assigned 
PG I entries in the HMT; and (3) remove references to special provision 
A6 from assigned liquids in the HMT.
    Four solid materials (UN Nos. 1326, 1390, 1889 and 3417) are 
currently assigned special provisions A6 in the HMT. Unlike the liquids 
currently assigned special provision A6, these solid materials are not 
subject to the intermediate or secondary packaging provisions in Sec.  
173.27. PHMSA solicits public comment on maintaining special provision 
A6 for currently assigned solid materials or whether revisions to the 
packaging provisions for these materials should be considered in a 
future rulemaking

B. Quantity Limits for Portable Electronic Medical Devices Carried by 
Passengers, Crewmembers, and Air Operators (P-1649)

    Phillips Healthcare petitioned PHMSA to revise Sec.  
175.10(a)(18)(i) to increase the quantity limits applicable to the 
transportation of portable medical electronic devices (e.g., automated 
external defibrillators (AED); nebulizers; continuous positive airway 
pressure (CPAP) devices containing lithium metal batteries; and spare 
batteries) carried on aircraft by passengers and crewmembers. See P-
1649.\2\ The current HMR requirements limit all lithium metal batteries 
carried on an aircraft by passengers or crew for personal use to a 
lithium content of not more than 2 grams per battery. The ICAO TI allow 
portable medical electronic devices containing lithium metal batteries 
and spare batteries for these devices to contain up to 8 grams of 
lithium content per battery to be carried by passengers with the 
approval of the operator. The petitioner states:
---------------------------------------------------------------------------

    \2\ https://www.regulations.gov/docket?D=PHMSA-2015-0107.

    A global increase in air travel, as well as a growing aged 
population in many countries, makes it reasonable to assume that 
there will be a significant increase in older passengers and 
passengers with illness. An automated external defibrillator can 
---------------------------------------------------------------------------
make the difference between life and death during cardiac arrest.

The petitioner further asserts that the current HMR requirements 
prohibit many people who need to travel with their portable medical 
electronic devices from doing so because the lithium content exceeds 
the amount allowed.
    In addition, the petitioner notes that increasing the quantity 
limits for portable medical electronic devices containing lithium metal 
batteries and spare batteries would be consistent with section 828 of 
the ``FAA Modernization and Reform Act of 2012'' (Pub. L. 112-98, 126 
Stat. 133; Feb. 14, 2012),\3\ which prohibits the Secretary of 
Transportation from issuing or enforcing any regulation or other 
requirement regarding the air transportation of lithium cells or 
batteries if the requirement is more stringent than the requirements of 
the ICAO TI.
---------------------------------------------------------------------------

    \3\ See http://www.gpo.gov/fdsys/pkg/CRPT-112hrpt381/pdf/CRPT-112hrpt381.pdf.
---------------------------------------------------------------------------

    PHMSA agrees that harmonizing the HMR with the ICAO TI on the issue

[[Page 87512]]

portable medical electronic devices with lithium batteries is 
consistent with the intent of section 828 of the FAA Modernization and 
Reform Act. Therefore, we propose to amend Sec.  175.10 to align HMR 
provisions with those in the ICAO TI.
    The petitioner further asks that portable medical electronic 
devices with increased lithium contents be authorized for transport by 
passengers or crew members without the approval of the operator. PHMSA 
points the petitioner to the ICAO TI part 8, table 8-1 provisions with 
which we are proposing to harmonize and notes that, under the ICAO TI, 
approval of the operator is required for lithium metal battery powered 
portable medical electronic devices and their spare batteries exceeding 
2 grams of lithium content but not exceeding 8 grams of lithium 
content. PHMSA is not compelled by the reasoning in the petition to be 
less restrictive than what international standards currently prescribe. 
Moreover, we believe that operator approval can be an important safety 
provision, especially in the context of large lithium metal batteries 
otherwise forbidden for transportation in carry-on or checked baggage. 
Accordingly, PHMSA does not propose to eliminate the operator approval 
provision.
    In this NPRM, we propose to amend Sec.  175.10(a)(18)(i) to 
authorize passengers and crewmembers to carry on board an aircraft 
lithium metal battery-powered portable medical electronic devices and 
two spare batteries for those devices exceeding 2 grams of lithium 
content per battery, but not exceeding 8 grams of lithium content per 
battery, with the approval of the operator.
    Consistent with the ICAO TI and the current HMR prohibitions, spare 
lithium batteries (i.e., batteries that are not packed with or 
contained in equipment) of any type and for any application continue to 
be prohibited from checked baggage. FAA's Safety Alert to Operators 
(SAFO) 15010 Carriage of Spare Lithium Batteries in Carry-on and 
Checked Baggage provides additional guidance to operators on this 
issue.

C. NOTOC Harmonization With the ICAO TI (P-1487)

    The United Parcel Service petitioned PHMSA to revise the 
notification of the captain/pilot-in-command (NOTOC) requirements to 
match the ICAO TI. The pilot-in-command must receive the NOTOC in order 
to appropriately consider the presence, amount and location of 
hazardous materials onboard the aircraft in an emergency. See P-
1487.\4\ This information, which also includes the hazard 
classification, proper shipping name, and packing group of the hazmat 
onboard the aircraft can help to inform the flight crew's decision-
making. If an in-flight emergency did occur, the flight crew or the air 
carrier's ground personnel would need to convey information to air 
traffic control and/or emergency responders in order to support a safe 
and effective response.
---------------------------------------------------------------------------

    \4\ https://www.regulations.gov/docket?D=PHMSA-2006-26159.
---------------------------------------------------------------------------

    In its petition, the United Parcel Services asks PHMSA to amend the 
domestic NOTOC requirements in Sec.  175.33 to reduce what it considers 
extraneous information and more closely align the HMR with existing 
international practices. The petitioner stated that harmonization with 
more elements of the ICAO TI's NOTOC requirements will reduce the 
regulatory burden for operators, as well as the costs associated with 
training employees and contract personnel to two sets of standards.
    PHMSA proposes adding each of the following requirements to the 
HMR: (a) The operator must provide to the flight dispatcher the same 
information as provided on the NOTOC; (b) the information must be 
provided to pilots and dispatchers prior to an aircraft moving under 
its own power; (c) the air operator must retain the pilot-in-command's 
confirmation via signature or other appropriate indication that the 
required information was received; and (d) the person responsible for 
loading must provide a signed confirmation or other form of indication 
that no damaged or leaking packages or packages showing evidence of 
damage or leakage were loaded on the aircraft. These changes and other 
general changes discussed below will result in PHMSA harmonizing more 
closely with the ICAO TI in regards to the information required to be 
provided in the NOTOC.
     Requirement that the operator provide the same information 
to the flight dispatcher that is required to be provided to the pilot-
in-command. In an emergency, a dispatcher may be more readily able to 
communicate with air traffic control and emergency responders about the 
nature and location of hazardous materials onboard an aircraft than the 
flight crew. Harmonizing with the ICAO TI and requiring dispatchers to 
have the same information as pilots regarding the nature, amounts, and 
locations of hazardous materials improves information sharing in an 
emergency situation. The current ICAO requirement to provide 
information to the dispatcher was proposed by the U.S. Panel Member on 
the ICAO Dangerous Goods Panel after consultation with stakeholders.\5\ 
Incorporating this provision into the HMR is also relevant to NTSB 
Safety Recommendation A-11-042, which recommends that the FAA ``develop 
a method to quickly communicate information regarding the number of 
persons on board and the presence of hazardous materials to emergency 
responders when airport emergency response or search and rescue is 
activated.'' \6\
---------------------------------------------------------------------------

    \5\ See ICAO Dangerous Goods Panel Working Paper DGP/23-WP/35 
(October 2011). In addition to regularly occurring public meetings 
before ICAO meetings, the FAA and PHMSA held a public meeting 
specific to NOTOCs in March 2011. For background information, visit: 
https://www.federalregister.gov/articles/2011/03/01/2011-4237/notification-of-pilot-in-command-notice-of-public-meeting.
    \6\ See http://www.ntsb.gov/safety/safety-recs/recletters/A-11-039-047.pdf.
---------------------------------------------------------------------------

    For operations subject to the HMR where no dispatcher is required, 
other personnel with responsibilities for operational control of the 
aircraft (e.g., the flight operations officer or designated ground 
personnel responsible for flight operations) would serve as the 
additional contact. Consistent with the ICAO TI, operators are 
responsible for addressing in their relevant manuals the job title and 
specific functions of the person who will receive this information.
    Providing an additional and potentially quicker means for airport 
rescue and firefighting (ARFF) personnel to receive the NOTOC 
underscores that the ARFF community is as much an intended consumer of 
the NOTOC as flight crews. We note that ARFF training in hazardous 
materials incidents is required under 14 CFR 139, which specifies the 
FAA's requirements for certificated airports.
     Requirement that the NOTOC be provided to pilots and 
dispatchers prior to an aircraft moving under its own power. The 
current HMR require pilots-in-command to receive written information 
meeting the requirements in Sec.  175.33 as early as practicable before 
departure of the aircraft. Consistent with the ICAO TI, PHMSA believes 
that this information should be provided to both the pilot-in-command 
and dispatchers prior to the aircraft moving under its own power. The 
flight crew should not be burdened with additional information or 
processes during taxiing and final preparations for takeoff. This 
proposed change would also allow the flight crew additional time to 
address any safety concerns identified after a

[[Page 87513]]

review of the NOTOC before taxiing. For example, flight crews will be 
more likely to have the opportunity to physically inspect (e.g., 
packages, paperwork, etc.), ask questions, or otherwise act on the 
information in the NOTOC if they so choose.
     Requirement that the air operator obtains and retains a 
confirmation (e.g., a signed confirmation from the pilot-in-command or 
notation via an operator's computer system) that the NOTOC was received 
by the pilot in command. The current HMR require the information to be 
provided to the pilot-in-command by the operator and for the operator 
to maintain a record of the NOTOC for 90 days, but there is no 
requirement for the pilot to indicate receipt of the NOTOC. To be 
consistent with the ICAO TI, PHMSA is proposing to require the operator 
to obtain and retain documentation of the pilot-in-command's receipt of 
the NOTOC.
     Requirement for a signed confirmation or some other 
indication from the person responsible for loading the aircraft that no 
evidence of damaged or leaking packages were loaded on the aircraft. 
The current HMR require a confirmation that no damaged or leaking 
packages were loaded on board an aircraft, but there is no requirement 
for a signature or other means of verification from the person 
responsible for loading the aircraft. Requiring a signed confirmation 
or other indication from the person responsible for loading results in 
a more accountable safety system that helps to ensure that there is no 
evidence of damage to or leakage from the packages or evidence of 
leakage from the unit load device loaded on an aircraft. Operators are 
responsible for addressing in their relevant manuals the job title and 
specific functions of the ``responsible loader,'' as well as how 
information should be communicated from other loaders to the 
responsible loader for each flight prior to this confirmation/
indication being provided on the NOTOC.
     General harmonization with the ICAO TI in regards to 
information required to be provided in the NOTOC associated with (and 
linked to) requirements for shipping papers. The current HMR require 
the additional description requirements of Sec. Sec.  172.202 and 
172.203 to be provided in the NOTOC. These additional information 
requirements necessitate the inclusion of items such as descriptions of 
the physical or chemical form of radioactive materials, an indication 
that the materials being transported are packaged under limited 
quantity exceptions, an indication that marine pollutants are present, 
etc. By more closely aligning with the ICAO TI, PHMSA believes that the 
removal of additional description requirements from the NOTOC will 
result in decreased complexity and training costs for operators without 
negatively impacting safety. However, we invite comment from the ARFF 
community pertaining to the effect this proposed rule would have had on 
past incident or accident responses.
    The current HMR contain a requirement that a notification prepared 
in accordance with the ICAO TI must also include any additional 
elements required to be shown on shipping papers by subpart C of part 
171 of this subchapter. The additional elements currently required are: 
An indication of the ``EX Number'' for Division 1.4G safety devices; an 
indication of ``RQ'' and technical names if applicable for hazardous 
substances; an indication that the hazardous material is a ``Waste'' 
for hazardous wastes; and the inclusion of the words ``Poison-
Inhalation Hazard'' or ``Toxic-Inhalation Hazard'' and the words ``Zone 
A,'' ``Zone B,'' ``Zone C,'' or ``Zone D'' for gases, or ``Zone A'' or 
``Zone B'' for liquids, as appropriate for Division 2.3 materials 
meeting the definition of a material poisonous by inhalation. PHMSA 
proposes to remove the requirement for a NOTOC made in accordance with 
the ICAO TI to include these additional elements. This information 
would still be required on shipping papers.
    General harmonization between the HMR NOTOC requirements and those 
found in the ICAO TI will ensure consistency for operators subject to 
both regulatory systems, thus reducing inconsistencies and the cost of 
complying with two different sets of standards. However, minor 
differences between the two regulations will remain even if PHMSA 
adopts the provisions of this NPRM into a final rule. One noteworthy 
difference is that the HMR requires that the date of the flight be 
included on the NOTOC. We believe that maintaining the flight date 
provides a benefit by adding another safety control to ensure pilots 
have the correct form and will result in a negligible compliance burden 
by those required to prepare and maintain a NOTOC under the HMR.

D. Amendments to Package Inspection (P-1671) and Securing Requirements

    Labelmaster Services petitioned PHMSA to amend Sec.  175.30(c)(1) 
by removing language prohibiting any package, outside container, or 
overpack containing hazardous materials from being transported on an 
aircraft if it has holes. See P-1671.\7\ The petitioner notes that 
airlines and freight forwarders have declined to transport packages 
with minor abrasions, tears, dents, cuts, small holes, or other minor 
damage from normal conditions of transportation and handling. Even 
where these examples of minor damage or holes did not compromise the 
packaging's integrity, airlines and freight forwarders declined to 
transport them on the basis of Sec.  175.30(c)(1). The petitioner asks 
that PHMSA add a new paragraph Sec.  173.24(b)(5) to provide transport 
guidance on packages with minor damage, as the HMR do not presently 
address this issue.
---------------------------------------------------------------------------

    \7\ https://www.regulations.gov/docket?D=PHMSA-2015-0281.
---------------------------------------------------------------------------

    PHMSA agrees that the wording of the current requirement may be 
construed to prohibit carriage of such items whenever any hole is found 
in the package, outside container, or overpack. PHMSA believes the 
current restriction prohibiting acceptance of any of these containment 
methods with holes to be overly prescriptive, especially as the 
paramount safety requirement is that there must not be any indication 
that the integrity of the containment method has been compromised. In 
this NPRM, consistent with the ICAO TI, PHMSA proposes to amend Sec.  
175.30(c)(1) to remove language prohibiting packages, outside 
containers, or overpacks containing hazardous materials from being 
transported on an aircraft simply due to the presence of holes when the 
holes do not compromise the integrity of the containment device. Under 
the proposed amendment to Sec.  175.30(c)(1), aircraft operators would 
be authorized to accept packages with small holes that do not 
compromise the integrity of the containment method during 
transportation aboard an aircraft. However, we note that operators may 
continue to have more restrictive standards as a part of their business 
practice. Moreover, operators are ultimately responsible for their 
decision to accept such a package for transportation, as the acceptance 
of the package is tantamount to the operator's determination that the 
hole will not compromise the integrity of the package.
    The petitioner's request to add a new paragraph in Sec.  173.24 is 
outside the scope of this rulemaking and may be considered in a future 
rule.
    Additionally, we propose to amend Sec.  175.88(c) to require 
hazardous materials loaded in an aircraft be protected from damage, 
including by the

[[Page 87514]]

movement of baggage, mail, stores,\8\ or other cargo and during loading 
operations, so that accidental damage is not caused through dragging or 
mishandling.
---------------------------------------------------------------------------

    \8\ References to stores in this rule are consistent the ICAO 
TI's definition under ICAO TI Part 1; 3.1.1.
    Stores (supplies). a) Stores (supplies) for consumption; and b) 
Stores (supplies) to be taken away.
    Stores (supplies) for consumption. Goods, whether or not sold, 
intended for consumption by the passengers and the crew on board 
aircraft, and goods necessary for the operation and maintenance of 
aircraft, including fuel and lubricants.
    Stores (supplies) to be taken away. Goods for sale to the 
passengers and the crew of aircraft with a view to being landed.
---------------------------------------------------------------------------

III. Section-by-Section Review

    The following is a section-by-section review of the amendments 
proposed in this NPRM:

Part 172

Section 172.101
    Section 172.101 contains the Hazardous Materials Table (HMT) and 
provides instructions for its use. Section 172.101(h) describes column 
(7) of the HMT, which specifies codes for special provisions applicable 
to hazardous materials. PHMSA proposes revisions to the column (7) 
special provisions. Please review all changes for a complete 
understanding of the amendments and see ``Section 172.102 special 
provisions'' for a detailed discussion of the proposed deletions to the 
special provisions addressed in this NPRM.
    PHMSA specifically proposes to remove: (1) Special provision A3 
from all assigned PG I HMT entries in column (7); and (2) special 
provision A6 from all assigned liquid HMT entries in column (7). Table 
1 illustrates the HMT entries for which changes are proposed:

Section 172.102 Special Provisions
    Section 172.102 lists special provisions applicable to the 
transportation of specific hazardous materials. Special provisions 
contain packaging requirements, prohibitions, and exceptions applicable 
to particular quantities or forms of hazardous materials. PHMSA 
proposes, to replace the existing requirement for tightly closed metal 
receptacles in special provision A3 from Sec.  172.102(b)(2), which 
applies only to transportation by aircraft, with a requirement for 
rigid and leakproof receptacles or intermediate packaging packed with 
absorbent material.

Part 175

Section 175.10
    Section 175.10 provides exceptions for passengers, crewmembers, and 
air operators. PHMSA proposes to revise Sec.  175.10(a)(18)(i) to 
authorize passengers and crewmembers to carry on board aircraft 
portable medical electronic devices containing lithium metal batteries 
with a lithium content exceeding 2 grams per battery, but not exceeding 
8 grams of lithium content per battery, and no more than two 
individually protected lithium metal spare batteries for these portable 
medical electronic devices each exceeding 2 grams of lithium content, 
but not exceeding 8 grams of lithium content, with the approval of the 
operator. Consistent with the ICAO TI and the current HMR prohibitions, 
spare lithium batteries (i.e. batteries that are not packed with or 
contained in equipment) of any type and for any application continue to 
be prohibited from checked baggage. FAA's Safety Alert to Operators 
(SAFO) 15010 Carriage of Spare Lithium Batteries in Carry-on and 
Checked Baggage provides additional guidance to operators on this 
issue.
Section 175.30
    Section 175.30 prescribes requirements for the inspection and 
acceptance of hazardous materials. PHMSA proposes revising Sec.  
175.30(c)(1) to no longer prohibit packages, outside containers, 
overpacks, or ULDs containing hazardous materials from being 
transported on an aircraft if there are one or more holes present when 
the hole(s) or other indications do not indicate compromised integrity 
to the package, overpack, freight container, or ULD. This change will 
harmonize the HMR with language in ICAO TI part 7; 1.3.1(i), which 
states ``the package, overpack, freight container or unit load device 
is not leaking and there is no indication that its integrity has been 
compromised.''
Section 175.33
    Section 175.33 establishes requirements for shipping papers and for 
the notification of the pilot-in-command (NOTOC) when hazardous 
materials are transported by aircraft. PHMSA proposes to harmonize the 
HMR NOTOC requirements with those found in the ICAO TI. Specifically, 
we propose to more closely align the information that is required to be 
provided in the NOTOC; ensure the NOTOC is provided to dispatchers or 
when dispatchers are not utilized, other ground support personnel 
designated in the operator's manual assigned to the flight; harmonize 
with ICAO requirements addressing when the NOTOC must be provided to 
the pilots and dispatchers; require confirmation via signature or other 
appropriate indication by the pilot-in-command (PIC) to indicate that 
the required information was received; and require confirmation via 
signature or other appropriate indication by the person responsible for 
loading the aircraft that no damaged or leaking packages or packages 
showing evidence of damage or leakage have been loaded on the aircraft.

[[Page 87516]]

    Finally, and consistent with the ICAO TI, we propose to amend Sec.  
175.33 by removing the requirement to include additional informational 
requirements in Sec.  175.33(a)(1)(i) and (ii). This information will 
continue to be required on shipping papers.
Section 175.88
    Section 175.88 prescribes requirements for inspection, orientation, 
and securing packages of hazardous materials aboard aircraft. PHMSA 
proposes revisions to Sec.  175.88(c) to require hazardous materials 
loaded in an aircraft to be protected from damage, including by the 
movement of baggage, mail, stores, or other cargo, consistent with 
general loading requirements found in the ICAO TI. This proposed change 
would require that packages be protected from damage during loading 
operations through dragging or mishandling of packages containing 
hazardous materials and further harmonize specific portions of the 
general loading/securement requirements pertaining to appropriate 
securing and loading practices of the HMR with those found in the ICAO 
TI.

IV. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This proposed rule is published under the statutory authority of 
the Federal hazardous materials transportation law (Federal hazmat 
law). 49 U.S.C. 5101 et seq. Section 5103(b) of the Federal hazmat law 
authorizes the Secretary of Transportation to prescribe regulations for 
the safe transportation, including security, of hazardous materials in 
intrastate, interstate, and foreign commerce. Section 5120(b) of the 
Federal hazmat law authorizes the Secretary of Transportation to ensure 
that, to the extent practicable, regulations governing the 
transportation of hazardous materials in commerce are consistent with 
standards adopted by international authorities. The Secretary has 
delegated these authorizations to the Administrator for PHMSA. See 49 
CFR 1.97.
    This rule proposes to amend regulations to increase alignment with 
international standards by incorporating various amendments, including 
changes to special provisions, packaging requirements, air transport 
notification of pilot-in-command (NOTOC) requirements, and allowances 
for hazardous materials to be carried on board an aircraft by 
passengers and crewmembers. To this end, this rule proposes to more 
fully align the HMR with the ICAO TI. The large volume of hazardous 
materials transported in international commerce warrants the 
harmonization of domestic and international requirements to the 
greatest extent possible.
    Harmonization serves to facilitate international commerce, while 
also promoting the safety of people, property, and the environment by 
reducing the potential for confusion and misunderstanding that could 
result if shippers and operators were required to comply with two or 
more conflicting sets of regulatory requirements. PHMSA's goal is to 
harmonize without sacrificing the current HMR level of safety or 
imposing undue burdens on the regulated community. Additionally, we 
consulted the Federal Aviation Administration in the development of 
this rule.

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) of Executive Order 12866, ``Regulatory 
Planning and Review,'' 58 FR 51735 (Oct. 4, 1993), and, therefore, was 
not reviewed by the Office of Management and Budget. This proposed rule 
is not considered a significant rule under the Regulatory Policies and 
Procedures of the Department of Transportation. 44 FR 11034 (Feb. 26, 
1979).
    Executive Order 13563, ``Improving Regulation and Regulatory 
Review,'' 76 FR 3821 (Jan. 21, 2011), supplements and reaffirms 
Executive Order 12866, stressing that, to the extent permitted by law, 
an agency rulemaking action must be based on benefits that justify its 
costs, impose the least burden, consider cumulative burdens, maximize 
benefits, use performance objectives, and assess available 
alternatives.
Benefits of Harmonization
    Pursuant to Executive Order 13563, PHMSA analyzed the expected 
benefits of these proposed provisions. Typically the benefits of rules 
are derived from (1) enhanced health and safety factors and (2) reduced 
expenditures, such as private-sector savings, government administrative 
savings, gains in work time, harmonization impacts, and costs of 
compliance. In the case of this NPRM, most of the benefits from the 
rule will be derived from health and safety factors, and reduced 
compliance costs.
    The quantifying health and safety benefits specifically 
attributable to modifications of the NOTOC requirements are not easily 
calculable with any degree of accuracy. The pilot signature and 
stronger confirmation requirements from the person responsible for 
loading the aircraft will result in more effective and efficient 
response in the event of an aviation incident. The proposed requirement 
that packages be protected from damage during loading operations will 
result in increased safety and environmental protection. Benefits would 
also be realized through a more efficient response time as a result of 
emergency response personnel having quicker access to hazardous 
materials information for each flight.
    The primary reduced expenditures benefits expected from this NPRM 
result from reduced packaging costs in relation to the removal of 
special provision A3 from all assigned PG I HMT entries and special 
provision A6 from all assigned liquid HMT entries, as well as cost 
savings from general harmonization of NOTOC requirements.
    Currently, compliance with special provisions A3 and A6 requires 
domestic shippers to use extra \9\ or more expensive \10\ materials. 
Shippers also incur higher freight charges for shipping packages with 
higher package weights.\11\ PHMSA estimates that the partial removal of 
A3 and complete removal of A6 for liquids, as well as that of the 
associated intermediate packaging requirements, from the HMR will 
provide an undiscounted annual benefit of $1,814,643 in reduced 
packaging costs to shippers.
---------------------------------------------------------------------------

    \9\ A metal container enclosing either a plastic or glass 
container.
    \10\ A metal or glass container rather than a plastic container.
    \11\ Having a metal container enclosing a plastic/glass 
container will add weight. Likewise using a metal or glass container 
rather than a plastic container will add weight.
---------------------------------------------------------------------------

    To arrive at this benefit, PHMSA (1) analyzed commodity flow survey 
data for commodities assigned A3, A6, or both in the HMR, (2) 
determined an estimate of total tons of freight for affected 
commodities offered for transportation by aircraft annually, (3) used 
this general commodity flow survey data to estimate the number of 
impacted packages, and (4) determined a cost basis for packages 
prepared under existing requirements versus proposed requirements.
    The reduced expenditure cost savings associated with general 
harmonization are not easily calculable with any degree of accuracy. 
Inconsistent hazardous materials regulations result in additional 
compliance costs for industry and increase compliance training efforts, 
whereas consistency of regulations reduces regulatory compliance costs 
and helps to avoid rejected or frustrated shipments.

[[Page 87517]]

PHMSA expects the increased harmonization of the HMR and ICAO TI NOTOC 
provisions to generate cost savings by streamlining the processes for 
NOTOC generation.
Costs of Harmonization
    The primary costs associated with this NPRM are time costs related 
to proposed requirements for (1) confirmation via signature or other 
appropriate indication by the person responsible for loading the 
aircraft that no damaged or leaking packages were loaded on the 
aircraft, and (2) confirmation via signature or other appropriate 
indication by the pilot-in-command to indicate that the required 
information was received. PHMSA estimates the annual costs associated 
with harmonizing the HMR NOTOC requirements with those found in the 
ICAO TI to be $705,590. PHMSA notes that many air operators already 
comply with the ICAO TI NOTOC requirements; therefore, the estimated 
cost of harmonizing likely is overestimated in this analysis. The HMR 
currently requires confirmation that no damaged or leaking packages 
have been loaded on the aircraft. In satisfying this current 
requirement, it is assumed that many operators are already using the 
proposed specific confirmation requirement (signature or other 
indication) from the person responsible loading the aircraft and are 
already be accounted for in time costs. Under current practice, the 
NOTOC is transmitted to the pilot-in-command. We assume the additional 
provision of identical NOTOC information to the dispatcher (or other 
personnel) will incur negligible costs, if any, especially as we 
understand this to be a common industry practice. PHMSA invites 
comments on this assumption and on any unanticipated costs associated 
with this proposed requirement.
    PHMSA expects the adoption of the proposal to eliminate the 
intermediate packaging requirements provided in special provision A6 
for liquids (and A3 for PG I materials) to yield a modest increase in 
safety costs due to increased transport volumes that may result from 
the reduced packaging costs. Based on an estimated 10 percent increase 
in transport volumes of commodities currently assigned special 
provisions A3 and A6, PHMSA estimates the annual increased safety cost 
attributable to the removal of these special provisions as proposed in 
this NPRM is $2,051.
Net Benefit
    Based on the previous discussions of benefits and costs, PHMSA 
estimates the net benefit associated with this NPRM (2137-AF10) to be 
$1,107,002.

C. Executive Order 13132

    This proposed rule was analyzed in accordance with the principles 
and criteria contained in Executive Order 13132, ``Federalism,'' 64 FR 
43255 (Aug. 10, 1999). This proposed rule may 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. 5101-
5128, contains an express preemption provision, 49 U.S.C. 5125(b), that 
preempts State, local, and Indian tribe requirements on certain covered 
subjects, as follows:
    (1) The designation, description, and classification of hazardous 
material;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous material;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous material and requirements related to the number, 
contents, and placement of those documents;
    (4) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; and
    (5) The design, manufacture, fabrication, inspection, marking, 
maintenance, recondition, repair, or testing of a packaging or 
container represented, marked, certified, or sold as qualified for use 
in transporting hazardous material in commerce.
    This proposed rule addresses covered subject items (2), (3), and 
(5) above and preempts State, local, and Indian tribe requirements not 
meeting the ``substantively the same'' standard. This proposed rule is 
necessary to harmonize with international standards. If the proposed 
changes are not adopted into the HMR, U.S. companies--including 
numerous small entities competing in foreign markets--would be at an 
economic disadvantage because of their need to comply with a dual 
system of regulations. The changes in this proposed rulemaking are 
intended to avoid this result. Federal hazardous materials 
transportation law provides at 49 U.S.C. 5125(b)(2) that, if DOT issues 
a regulation concerning any of the covered subjects, DOT must determine 
and publish in the Federal Register the effective date of Federal 
preemption. The effective date may not be earlier than the 90th day 
following the date of issuance of the final rule and 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.

D. Executive Order 13175

    This proposed rule was analyzed in accordance with the principles 
and criteria contained in Executive Order 13175, ``Consultation and 
Coordination with Indian Tribal Governments,'' 65 FR 67249 (Nov. 9, 
2000). Because this proposed rule does not have tribal implications, 
does not impose substantial direct compliance costs, and is required by 
statute, the funding and consultation requirements of Executive Order 
13175 do not apply.

E. Regulatory Flexibility Act, Executive Order 13272, and DOT Policies 
and Procedures

    This proposed rule was developed in accordance with Executive Order 
13272, ``Proper Consideration of Small Entities in Agency Rulemaking,'' 
67 FR 53461 (Aug. 16, 2002), and DOT's Policies and Procedures to 
promote compliance with the Regulatory Flexibility Act, 5 U.S.C. 601 et 
seq., and ensure that potential impacts of draft rules on small 
entities are properly considered. The Regulatory Flexibility Act 
requires an agency to review regulations to assess their impact on 
small entities, unless the agency determines that a rule is not 
expected to have a significant impact on a substantial number of small 
entities.
    This proposed rule facilitates the transportation of hazardous 
materials in international commerce by increasing consistency with 
international standards. It applies to offerors and carriers of 
hazardous materials, some of whom are small entities, such as chemical 
manufacturers, users and suppliers, packaging manufacturers, 
distributors, aircraft operators, and training companies. As previously 
discussed in Section IV, Subsection B (``Executive Order 12866, 
Executive Order 13563, and DOT Regulatory Policies and Procedures''), 
PHMSA expects that the majority of amendments in this proposed rule 
will result in cost savings and ease the regulatory compliance burden 
for shippers engaged in domestic and international commerce, including 
trans-border shipments within North America. Many companies will 
realize economic benefits as a result of these amendments. 
Additionally, the changes effected by this NPRM will relieve U.S. 
companies, including small entities competing in foreign markets, from 
the

[[Page 87518]]

burden of complying with a dual system of regulations. However, PHMSA 
requests comment on the economic impacts of the proposed rule on a 
small entities.

F. Paperwork Reduction Act

    PHMSA currently has approved information collection under Office of 
Management and Budget (OMB) Control Number 2137-0034, ``Hazardous 
Materials Shipping Papers and Emergency Response Information.'' We 
anticipate that this proposed rule will result in an increase in the 
annual burden of this information collection because of an increase in 
the amount of time needed to complete the NOTOC due to additional 
requirements for (1) confirmation via signature or other appropriate 
indication by the person responsible for loading the aircraft that no 
damaged or leaking packages were loaded on the aircraft, and (2) 
confirmation via signature or other appropriate indication by the 
pilot-in-command that the required information was received.
    This rulemaking identifies a revised information collection that 
PHMSA will submit to OMB for approval based on the requirements in this 
NPRM. PHMSA has developed burden estimates to reflect changes in this 
NPRM and estimates that the information collection and recordkeeping 
burden in this rule are as follows:
    OMB Control Number: 2137-0034.
    Annual Increase in Number of Respondents: 150.
    Annual Increase in Annual Number of Responses: 1,976,475.

    Under the Paperwork Reduction Act of 1995, no person is required to 
respond to an information collection unless it has been approved by OMB 
and displays a valid OMB control number. Section 1320.8(d) of 5 CFR 
requires that PHMSA provide interested members of the public and 
affected agencies an opportunity to comment on information and 
recordkeeping requests. PHMSA specifically invites comments on the 
information collection and recordkeeping burdens associated with 
developing, implementing, and maintaining these proposed requirements. 
Address written comments to the Dockets Unit as identified in the 
ADDRESSES section of this rulemaking. We must receive comments 
regarding information collection burdens prior to the close of the 
comment period as identified in the DATES section of this rulemaking. 
In addition, you may submit comments specifically related to the 
information collection burden to PHMSA Desk Officer, Office of 
Management and Budget, at fax number 202-395-6974. Requests for a copy 
of this information collection should be directed to Steven Andrews or 
T. Glenn Foster, Standards and Rulemaking Division (PHH-10), Pipeline 
and Hazardous Materials Safety Administration, 1200 New Jersey Avenue 
SE., Washington, DC 20590-0001. If these proposed requirements are 
adopted in a final rule, PHMSA will submit the revised information 
collection and recordkeeping requirements to OMB for approval.

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 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 
$141.3 million or more, adjusted for inflation, to either State, local, 
or tribal governments, in the aggregate, or to the private sector in 
any one year, 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 
that implement NEPA, 40 CFR parts 1500-1508, 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 both the proposed action and the 
alternatives, and (4) the agencies and persons consulted during the 
consideration process. 40 CFR 1508.9(b).
1. Purpose and Need
    In this NPRM, PHMSA proposes to amend the HMR in to increase 
harmonization with international standards and to address four 
petitions for rulemaking submitted by shippers, carriers, 
manufacturers, and industry representatives. These proposed revisions 
are intended to harmonize with international standards, while also 
maintaining or enhancing safety. Specifically, PHMSA, consistent with 
P-1487, proposes to harmonize the HMR with the 2015-2016 ICAO TI 
requirements for the NOTOC, the ICAO TI requirement for the air 
operator to provide a copy of the NOTOC to the flight dispatcher, and 
the ICAO TI requirement for the air operator to obtain and retain a 
confirmation that the NOTOC was received and agreed to by the pilot. 
This NPRM addresses three additional petitions for rulemaking (P-1637, 
P-1649, and P-1671), proposing to: (1) More closely harmonize with the 
ICAO TI in regard to intermediate packaging requirements for certain 
low and medium danger hazardous materials; (2) add an exception to 
allow passengers to bring on board an aircraft portable medical 
electronic devices containing lithium batteries that exceed the lithium 
battery limits in Sec.  175.10(a)(18)(i), as well as spare batteries 
for these devices with the approval of the operator; and (3) remove 
language prohibiting any package, outside container, or overpack 
containing hazardous materials from being transported on an aircraft if 
it has holes when there is no indication that the integrity of the 
containment method has been compromised. All of these proposals more 
closely harmonize U.S. regulations with international standards.
    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) align the HMR with 
international transport standards and requirements to the extent 
practicable in accordance with Federal hazmat law, see 49 U.S.C. 5120; 
and (4) simplify and clarify the regulations in order to promote 
understanding and compliance. Specifically, this rulemaking achieves 
these goals by responding to petitions (P-1487, P-1637, P-1649, and P-
1671).
    With this action, we intend to more closely align the HMR with 
international transport standards and requirements, without diminishing 
the level of safety currently provided by the HMR or imposing undue 
burdens on the regulated public.

[[Page 87519]]

2. Alternatives
    In proposing this rulemaking, PHMSA is considering the following 
alternatives:
    No Action Alternative:
    If PHMSA were to choose this alternative, we would not proceed with 
any rulemaking on this subject and the current regulatory standards 
would remain in effect.
    Preferred Alternative:
    This alternative is the current proposal as it appears in this 
NPRM, applying to transport of hazardous materials by air. The proposed 
amendments included in this alternative are more fully addressed in the 
preamble and regulatory text sections of this NPRM. However, they 
generally include the following:
    (1) More closely harmonize the HMR and ICAO TI notification 
requirements. In this NPRM, PHMSA proposes to more closely align NOTOC 
requirements between the HMR and the ICAO TI. This includes information 
required in the notification, when the NOTOC must be provided to pilots 
and dispatchers, and requirements for verifying that the information 
was received by the pilot-in-command.
    (2) More closely harmonize with ICAO TI in regard to intermediate 
packaging requirements for certain low and medium danger hazardous 
materials. In this NPRM, PHMSA proposes to remove all references to 
special provision A6 assigned to liquids in the Hazardous Materials 
Table. Additionally, this NPRM proposes to amend special provision A3 
to authorize additional intermediate packagings.
    (3) Add an exception to allow passengers, with the approval of the 
operator, to bring on board an aircraft a portable medical electronic 
device that exceeds the lithium battery limits in Sec.  
175.10(a)(18)(i). In this NPRM, PHMSA proposes to amend Sec.  
175.10(a)(18)(i) to increase the quantity limits applicable to the 
transportation of portable medical electronic devices containing 
lithium metal batteries and spare batteries for these devices carried 
on an aircraft. The current HMR limit all lithium metal batteries to a 
lithium content of not more than 2 grams per battery regardless of end 
use, whereas the ICAO TI allow portable medical electronic devices 
containing lithium metal batteries to contain up to 8 grams of lithium 
(as well as spare batteries for these devices) to be carried on board 
an aircraft.
    (4) Amend the Package Inspection and Securing Requirements. In this 
NPRM, PHMSA proposes to amend Sec.  175.30(c)(1) to remove language 
prohibiting any package, outside container, or overpack containing 
hazardous materials from being transported on an aircraft if it has 
holes. Additionally, PHMSA proposes revisions to Sec.  175.88(c) to 
require hazardous materials loaded in an aircraft to be protected from 
damage, including by the movement of baggage, mail, stores, or other 
cargo, consistent with general loading requirements found in the ICAO 
TI.
3. Probable Environmental Impacts of the Alternatives
    No Action Alternative:
    If PHMSA were to choose the No Action Alternative, we would not 
proceed with any rulemaking on this subject and the current regulatory 
standards would remain in effect. However, efficiencies gained through 
harmonization in updates to transport standards would not be realized. 
Foregone efficiencies in the No Action Alternative include freeing up 
limited resources to concentrate on air transport hazard communication 
(hazcom) issues of potentially much greater environmental impact.
    Additionally, the Preferred Alternative encompasses enhanced and 
clarified regulatory requirements, which would result in increased 
compliance and less 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.
    Preferred Alternative:
    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. Consistency between U.S. and international notification 
requirements can enhance the safety and environmental protection of 
hazardous materials transportation, reduce compliance costs, increase 
the flow of hazardous materials from their points of origin to their 
points of destination (or diversion airport when required), and improve 
the emergency response in the event of a hazardous materials incident 
or accident.
    Overall, harmonization will result in more targeted and effective 
training and thereby enhanced environmental protection. These proposed 
amendments will reduce inconsistent hazardous materials regulations, 
which can increase the time and cost of compliance training. For ease 
of compliance with appropriate regulations, air carriers engaged in the 
transportation of hazardous materials generally elect to accept and 
transport hazardous materials in accordance with the ICAO TI, as 
appropriate. Increasing consistency between these international 
regulations and the HMR allows shippers and carriers to more 
efficiently train hazmat employees in their responsible functions. 
PHMSA believes that these proposed amendments, which will increase 
standardization and consistency of regulations, will result in greater 
protection of human health and the environment:
    (1) More closely harmonize the HMR and ICAO TI notification 
requirements. Harmonizing the HMR and ICAO TI notification requirements 
will (1) allow air carriers to streamline compliance and training 
programs, (2) result in emergency response personnel having quicker 
access to hazmat information for each flight, (3) remove the 
requirement to supply data elements required under shipping paper 
provisions, and (4) provide dispatchers access to hazmat information 
and relieve the flight crew of the responsibility of communicating this 
information to Air Traffic Control (ATC) and Aircraft Rescue and 
Firefighting (ARFF) personnel.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    (2) More closely harmonize with the ICAO TI in regard to 
intermediate packaging requirements for certain low and medium danger 
hazardous materials. Deleting the assignment of special provisions A3 
(partial) and A6 (for liquids) more closely harmonizes the HMR with the 
packing instructions of the ICAO TI and removes a requirement that, 
according to the petitioner, is a barrier to trade for U.S. exports, 
while still maintaining an appropriate level of safety. Existing 
requirements in Sec.  173.27(d) and (e) for inner packagings to have a 
secondary means of closure and to be placed in either a rigid and 
leakproof receptacle or an intermediate packaging with absorbent 
material make special provisions A3 and A6 redundant for PG I 
commodities. Additionally, the requirements in Sec.  173.27(d) for 
inner packagings to have a secondary means of closure or a leakproof 
liner or bag adequately address the hazards that special provision A6 
was designed to mitigate for PG II and III liquid materials.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.

[[Page 87520]]

    (3) Add an exception to allow passengers, with the approval of the 
operator, to bring on board an aircraft a portable medical electronic 
device that exceeds the lithium battery limits in Sec.  
175.10(a)(18)(i). Harmonizing with the ICAO TI in this area would 
assist the traveling public who rely on their portable medical 
electronic devices. This revision will be consistent with the FAA 
Modernization and Reform Act. PHMSA has found no data on increased 
incidents in countries allowing the ICAO TI lithium battery limits for 
portable electronic medical devices.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
    (4) Amend the Package Inspection and Securing Requirements. 
Harmonizing with the ICAO TI in this area will address the overly 
prescriptive requirements for package inspection and securing, which 
currently result in acceptance rejections from airlines and freight 
forwarders. Further, harmonization will result in more targeted and 
effective training and thereby enhanced environmental protection. These 
proposed amendments will reduce inconsistent hazardous materials 
regulations, which hamper compliance training efforts.
    Greenhouse gas emissions would remain the same under this proposed 
amendment.
4. Agencies Consulted
    PHMSA has coordinated with the U.S. Federal Aviation Administration 
in the development of this proposed rule. PHMSA will consider the views 
expressed in comments to the NPRM submitted by members of the public, 
State and local governments, and industry.
5. Conclusion
    The provisions of this proposed rule build on current regulatory 
requirements to enhance the transportation safety and security of 
shipments of hazardous materials transported by aircraft, thereby 
reducing the risks of an accidental or intentional release of hazardous 
materials and consequent environmental damage. PHMSA believes the net 
environmental impact will be positive and that there are no significant 
environmental impacts associated with this proposed rule.
    PHMSA welcomes any views, data, or information related to 
environmental impacts that may result if the proposed requirements are 
adopted, as well as possible alternatives and their environmental 
impacts.

J. Privacy Act

    Anyone is able to search the electronic form of any written 
communications and comments received into any of our dockets by the 
name of the individual submitting the document (or signing the 
document, if submitted on behalf of an association, business, labor

K. Executive Order 13609 and International Trade Analysis

    Under Executive Order 13609, ``Promoting International Regulatory 
Cooperation,'' 77 FR 26413 (May 4, 2012), agencies must consider 
whether the impacts associated with significant variations between 
domestic and international regulatory approaches are unnecessary or may 
impair the ability of American business to export and compete 
internationally. In meeting shared challenges involving health, safety, 
labor, security, environmental, and other issues, international 
regulatory cooperation can identify approaches that are at least as 
protective as those that are or would be adopted in the absence of such 
cooperation. International regulatory cooperation can also reduce, 
eliminate, or prevent unnecessary differences in regulatory 
requirements.
    Similarly, the Trade Agreements Act of 1979, Public Law 96-39, as 
amended by the Uruguay Round Agreements Act, Public Law 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. For purposes of these requirements, 
Federal agencies may participate in the establishment of international 
standards, so long as the standards have a legitimate domestic 
objective, such as providing for safety, and do not operate to exclude 
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 and the FAA participate in the establishment of international 
standards to protect the safety of the American public, and we have 
assessed the effects of the proposed rule to ensure that it does not 
cause unnecessary obstacles to foreign trade. In fact, the proposed 
rule is designed to facilitate international trade by eliminating 
differences between the domestic and international air transportation 
requirements. Accordingly, this rulemaking is consistent with Executive 
Order 13609 and PHMSA's obligations under the Trade Agreement Act, as 
amended.

L. National Technology Transfer and Advancement Act

    The National Technology Transfer and Advancement Act of 1995, 15 
U.S.C. 272 note, directs Federal agencies to use voluntary consensus 
standards in their regulatory activities unless doing so would be 
inconsistent with applicable law or otherwise impractical. Voluntary 
consensus standards are technical standards (e.g., specification of 
materials, test methods, or performance requirements) that are 
developed or adopted by voluntary consensus standard bodies. This 
proposed rule does not involve voluntary consensus standards.

5. In Sec.  175.10, paragraphs (a)(18) and (a)(18)(i) are revised to 
read as follows:

Sec.  175.10   Exceptions for passengers, crewmembers, and air 
operators.

    (a) * * *
    (18) Except as provided in Sec.  173.21 of this subchapter, 
portable electronic devices (e.g., watches, calculating machines, 
cameras, cellular phones, laptop and notebook computers, camcorders, 
medical devices etc.) containing dry cells or dry batteries (including 
lithium cells or batteries) and spare dry cells or batteries for these 
devices, when carried by passengers or crew members for personal use. 
Portable electronic devices powered by lithium batteries may be carried 
in either checked or carry-on baggage. Spare lithium batteries must be 
carried in carry-on baggage only. Each installed or spare lithium 
battery must be of a type proven to meet the requirements of each test 
in the UN Manual of Tests and Criteria, part III, sub-section 38.3 and 
each spare lithium battery must be individually protected so as to 
prevent short circuits (e.g., by placement in original retail 
packaging, by otherwise insulating terminals by taping over exposed 
terminals, or placing each battery in a separate plastic bag or 
protective pouch). In addition, each installed or spare lithium battery 
must not exceed the following:
    (i) For a lithium metal battery, the lithium content must not 
exceed 2 grams. With the approval of the operator, portable medical 
electronic devices (e.g. automated external defibrillators (AED), 
nebulizer, continuous positive airway pressure (CPAP), etc.) may 
contain lithium metal batteries exceeding 2 grams but not exceeding 8 
grams. No more than two individually protected lithium metal batteries 
each exceeding 2 grams, but not exceeding 8 grams, may be carried as 
spare batteries for portable medical electronic devices in carry-on 
baggage and must be carried with the portable medical electronic device 
they are intended to operate;

7. Section 175.33 is revised to read as follows:

Sec.  175.33  Shipping paper and notification of pilot-in-command.

    (a) When a hazardous material subject to the provisions of this 
subchapter is carried in an aircraft, a copy of the shipping paper 
required by Sec.  175.30(a)(2) must accompany the shipment it covers 
during transportation aboard the aircraft. The operator of the aircraft 
must provide the pilot-in-command and dispatcher (or other ground 
support personnel with responsibilities for operational control of the 
aircraft as designated in the operator's manual) assigned to the flight 
with accurate and legible written information as early as practicable 
before departure of the aircraft, but in no case later than when the 
aircraft moves under its own power, which specifies at least the 
following:
    (1) The air waybill number (when issued);
    (2) The proper shipping name, hazard class, subsidiary risk(s) 
corresponding to a required label(s), packing group and identification 
number of the material, including any remaining aboard from prior 
stops, as specified in Sec.  172.101 of this subchapter or the ICAO 
Technical Instructions (IBR, see Sec.  171.7 of this subchapter). In 
the case of Class 1 materials, the compatibility group letter also must 
be shown.
    (3) The total number of packages;
    (4) The location of the packages aboard the aircraft;
    (5) The net quantity or gross weight, as applicable, for each 
package except those containing Class 7 (radioactive) materials. For a 
shipment consisting of multiple packages containing hazardous materials 
bearing the same proper shipping name and identification number, only 
the total quantity and an indication of the quantity of the largest and 
smallest package at each loading location need to be provided. For 
consumer commodities, the information provided may be either the gross 
mass of each package or the average gross mass of the packages as shown 
on the shipping paper;
    (6) For Class 7 (radioactive) materials, the number of packages, 
overpacks or freight containers, their category, transport index (if 
applicable), and their location aboard the aircraft;
    (7) Confirmation that the package must be carried only on cargo 
aircraft if its transportation aboard passenger-carrying aircraft is 
forbidden;
    (8) The airport at which the package(s) is to be unloaded;
    (9) An indication, when applicable, that a hazardous material is 
being carried under terms of a special permit;
    (10) The telephone number of a person not aboard the aircraft from 
whom the information contained in the notification of pilot-in-command 
can be obtained. The aircraft operator must ensure the telephone number 
is monitored at all times the aircraft is in flight. The telephone 
number is not required to be placed on the notification of pilot-in-
command if the phone number is in a location in the cockpit available 
and known to the flight crew; and
    (11) The date of the flight;
    (12) For UN1845, Carbon dioxide, solid (dry ice), only the UN 
number, proper shipping name, hazard class, total quantity in each hold 
aboard the aircraft, and the airport at which the package(s) is to be 
unloaded must be provided.
    (13) For UN 3480, Lithium ion batteries, and UN 3090, Lithium metal 
batteries, the information required by paragraph (a) of this section 
may be replaced by the UN number, proper shipping name, class, total 
quantity at each specific loading location, and whether the package 
must be carried on cargo aircraft only. UN 3480 (Lithium ion batteries) 
and UN 3090 (Lithium metal batteries) carried under an approval must 
meet all of the requirements of this section.
    (b)(1) The information provided to the pilot-in-command must also 
include a signed confirmation or some other indication from the person 
responsible for loading the aircraft that there was no evidence of any 
damage to or leakage from the packages or any leakage from the unit 
load devices loaded on the aircraft;

[[Page 87529]]

    (2) A copy of the written notification to pilot-in-command shall be 
readily available to the pilot-in-command and dispatcher during flight. 
Emergency response information required by subpart G of part 172 of 
this subchapter must be maintained in the same manner as the written 
notification to pilot-in-command during transport of the hazardous 
material aboard the aircraft.
    (3) The pilot-in-command must indicate on a copy of the information 
provided to the pilot-in-command, or in some other way, that the 
information has been received.
    (c) The aircraft operator must--
    (1) Retain a copy of the shipping paper required by Sec.  
175.30(a)(2) or an electronic image thereof, that is accessible at or 
through its principal place of business and must make the shipping 
paper available, upon request, to an authorized official of a federal, 
state, or local government agency at reasonable times and locations. 
For a hazardous waste, each shipping paper copy must be retained for 
three years after the material is accepted by the initial carrier. For 
all other hazardous materials, each shipping paper copy must be 
retained by the operator for one year after the material is accepted by 
the initial carrier. Each shipping paper copy must include the date of 
acceptance by the carrier. The date on the shipping paper may be the 
date a shipper notifies the air carrier that a shipment is ready for 
transportation, as indicated on the air waybill or bill of lading, as 
an alternative to the date the shipment is picked up or accepted by the 
carrier. Only an initial carrier must receive and retain a copy of the 
shipper's certification, as required by Sec.  172.204 of this 
subchapter.
    (2) Retain a copy of each notification of pilot-in-command, an 
electronic image thereof, or the information contained therein for 90 
days at the airport of departure or the operator's principal place of 
business.
    (3) Have the information required to be retained under this 
paragraph readily accessible at the airport of departure and the 
intended airport of arrival for the duration of the flight leg.
    (4) Make available, upon request, to an authorized official of a 
Federal, State, or local government agency (which includes emergency 
responders) at reasonable times and locations, the documents or 
information required to be retained by this paragraph. In the event of 
a reportable incident, as defined in Sec.  171.15 of this subchapter, 
the aircraft operator must make immediately available to an authorized 
official of a Federal, State, or local government agency (which 
includes emergency responders), the documents or information required 
to be retained by this paragraph.
    (d) The documents required by paragraphs (a) and (b) this section 
may be combined into one document if it is given to the pilot-in-
command before departure of the aircraft.

hazardous materials.

* * * * *
    (c) Packages containing hazardous materials must be:
    (1) Secured in an aircraft in a manner that will prevent any 
shifting or change in the orientation of the packages;
    (2) Protected from being damaged, including by the movement of 
baggage, mail, stores, or other cargo;
    (3) Handled so that accidental damage is not caused through 
dragging or mishandling; and
    (4) When containing Class 7 (radioactive) materials, secured in a 
manner that ensures that the separation requirements of Sec. Sec.  
175.701 and 175.702 will be maintained at all times during flight.
