I. Background

    On December 5, 2016, PHMSA (also ``we''), in consultation with the 

Federal Aviation Administration (FAA), published a notice of proposed 

rulemaking (NPRM) [Docket No. PHMSA-2015-0100 (HM-259); 81 FR 87510] to 

amend the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180) 

to align more closely with certain provisions of the International 

Civil Aviation Organization's Technical Instructions for the Safe 

Transport of Dangerous Goods by Air (ICAO Technical Instructions). 

These amendments update miscellaneous regulatory requirements for 

hazardous materials offered for transportation, or transported, in 

commerce by aircraft. In addition, the NPRM proposed amendments in 

response to four petitions for rulemaking submitted by the regulated 

community. The petitions are included in the docket for this proceeding 

and are discussed at length in Section II (Comment Discussion) of this 

rulemaking. In the NPRM, the phrase ``notification to the pilot-in-

command'' and the acronym ``NOTOC'' were used. In this final rule, 

consistent with the ICAO Technical Instructions, the phrase 

``information to the pilot-in-command'' is used.

II. Comment Discussion

    In response to the NPRM [81 FR 87510], PHMSA received comments from 

the following organizations:

 Air Line Pilots Association (ALPA)

 Airlines for America (A4A)

 Council on Safe Transportation of Hazardous Articles (COSTHA)

 Dangerous Goods Advisory Council (DGAC)

 United Parcel Service (UPS)

See below for discussion of the comments received and PHMSA's 

determined action in this final rule. This section addresses comments 

made to proposals to revise the HMR based on petitions for rulemaking. 

Additional comments are addressed in Section III (Section-by-Section 

Review) of this rulemaking.

A. Transportation by Air Intermediate Packaging Requirements for 

Certain Low and Medium Danger Hazardous Materials (P-1637)

    The DGAC 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\ See 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 Technical Instructions 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

[[Page 52879]]

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) of the HMR 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 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 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 for transport by air. It requires 

that inner packagings be packed in a rigid and leakproof receptacle or 

intermediate packaging that is sufficiently absorbent to absorb the 

entire contents of the inner packaging before the inner package is 

packed in the outer package.

    In the NPRM, PHMSA proposed 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.

    PHMSA received positive feedback from commenters. Specifically, 

ALPA and UPS expressed support for this amendment. The DGAC also 

expressed support for the proposed amendment; however, consistent with 

their petition, DGAC continues to believe that the secondary closure 

requirements in Sec.  173.27(d) satisfy the provisions in A3, making A3 

unnecessary for PG II and III materials.

    As stated in the NPRM, PHMSA agrees that current requirements in 

Sec.  173.27(d) and (e) make special provisions A3 and A6 unnecessarily 

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. As commenters did not provide any 

supplemental information or justification for the removal of special 

provision A3 from the assigned PG II and III entries other than 

originally included in the petition, PHMSA maintains its position 

stated in the NPRM that the material of construction of the inner 

packaging referenced in special provision A3 (glass) necessitates an 

intermediate packaging to perform a containment function in the event 

an inner packaging breaks. Therefore, PHMSA is maintaining the 

intermediate packaging requirements for PG II and III materials in 

special provision A3; however, we are amending special provision A3 to 

authorize rigid and leakproof receptacles for use as intermediate 

packagings that are currently limited to metal construction. This will 

provide a wider range of intermediate packaging options to shippers of 

hazardous materials subject to special provision A3.

    Additionally, in the NPRM, PHMSA solicited 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. Special provision A6 is currently 

assigned to four solid materials (UN Nos. 1326, 1390, 1889, and 3417) 

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 received two comments in 

support of removing special provision A6 from the currently assigned 

solid materials. The DGAC commented that the special provision is 

unnecessary because these solid materials are not subject to the 

intermediate or secondary packaging requirements. UPS supports removing 

the special provision provided the packaging provisions in Sec.  173.27 

are modified to require secondary or intermediate containment for these 

commodities. Based on the comments received, PHMSA will consider 

removing special provision A6 from the four solid materials 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 crewmembers for personal use to 

a lithium content of not more than 2 grams per battery. The ICAO 

Technical Instructions 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 

stated:

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

    \2\ See 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 asserted 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 noted 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 Technical Instructions.

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

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

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

    In the NPRM, PHMSA proposed 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.

    PHMSA received three comments from A4A, COSTHA, and DGAC in support 

of the proposed amendment.

[[Page 52880]]

A4A commented that the current inability of passengers and crewmembers 

to carry lithium metal battery-powered portable medical electronic 

devices exceeding 2 grams imposes unnecessary travel restrictions for 

passengers with medical needs requiring the equipment. DGAC commented 

that harmonization with the ICAO Technical Instructions on this issue 

will benefit the travelers by allowing them to carry life-saving 

medical devices.

    In contrast, ALPA provided comments that oppose the proposed 

amendment, stating that they do not support changing regulations based 

on the end use of batteries. Specifically, ALPA notes ``batteries 

installed in a medical device can be the same as used in a non-medical 

device . . . and are not inherently safer than non-medical devices.'' 

PHMSA agrees with ALPA that hazardous materials are not generally 

regulated by end-use application when offered as cargo, but rather on 

the hazard posed during transport. In addition, PHMSA does not dispute 

ALPA's assertion that lithium batteries used in medical devices present 

the same hazard as lithium batteries used in non-medical devices. 

However, the exceptions for passengers and crewmembers prescribed in 

Sec.  175.10 do not apply to cargo consignments. Instead, they are 

based on the need of individual passengers and crewmembers to carry 

personal items containing relatively small quantities of hazardous 

materials for common ``end-use'' items subject to certain conditions. 

In the 2011-2012 edition of the ICAO Technical Instructions, the 2-gram 

limit was expanded for medical devices only. Specifically, the limit 

was expanded to allow for medical devices known to exceed these limits, 

notably Automated External Defibrillators (AEDs), which typically had a 

lithium content between 4 and 8 grams.\4\ Therefore, PHMSA is adopting 

the amendment to Sec.  175.10(a)(18) as proposed in the NPRM consistent 

with the provisions of the ICAO Technical Instructions.

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

    \4\ See paragraph 5.4.10 of ICAO Dangerous Goods Panel Working 

Paper DGP/22-WP/100 (October 2009).

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

    In addition to the comments above, A4A and COSTHA recommended that 

PHMSA extend this allowance for lithium metal battery-powered portable 

medical electronic devices exceeding current regulatory limits to all 

portable electronic devices powered by lithium metal batteries. They 

stated that maintaining differences between medical and non-medical 

devices increases training costs, adds confusion, and the risk of 

potential inadvertent non-compliance by aircraft operators who elect to 

approve portable medical devices exceeding 2 grams of lithium content 

per battery, but not exceeding 8 grams of lithium content per battery. 

As this proposal was not presented in the December 5, 2016 NPRM, it is 

considered beyond the scope of the rulemaking and is not addressed in 

this final rule.

C. Information to the Pilot-in-Command, Harmonization With the ICAO 

Technical Instructions (P-1487)

    UPS petitioned PHMSA to revise the information to the pilot-in-

command requirements to match the ICAO Technical Instructions. The 

pilot-in-command must receive the information in order to appropriately 

consider the presence, amount, and location of hazardous materials 

onboard the aircraft in an emergency. See P-1487.\5\ This information, 

which also includes the hazard classification, proper shipping name, 

and packing group of the hazardous materials onboard the aircraft can 

help inform the decision-making of the pilot-in-command. If an in-

flight emergency did occur, the pilot-in-command or the operator'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.

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

    \5\ See https://www.regulations.gov/docket?D=PHMSA-2006-26159.

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

    In its petition, UPS asked PHMSA to amend the domestic information 

to the pilot-in-command 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 Technical Instructions' 

information to the pilot-in-command 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.

    In the NPRM, PHMSA proposed adding each of the following 

requirements to the HMR:

    1. The operator must provide to the flight dispatcher \6\ the same 

information as provided on the information to the pilot-in-command;

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

    \6\ For the purposes of this rulemaking the ``flight 

dispatcher'' refers to the personnel with responsibilities for 

operational control of the aircraft (e.g., the flight operations 

officer, flight dispatcher, or designated ground personnel 

responsible for flight operations).

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

    2. The information must be provided to the pilot-in-command and 

flight dispatchers prior to an aircraft moving under its own power;

    3. The air operator must retain the pilot-in-command's confirmation 

via signature or other appropriate indication that the required 

information was received; and

    4. The person responsible for loading the aircraft 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.

    PHMSA received comments from A4A, ALPA, DGAC, COSTHA, and UPS 

providing general support for aligning the information to the pilot-in-

command requirements with the ICAO Technical Instructions. UPS 

commented, ``This action will improve consistency between the HMR and 

ICAO, thereby promoting clarity of requirements, and overall compliance 

and safety in flight for operations around the world.'' DGAC commented, 

``. . . Harmonizing the provisions of the HMR with those in the ICAO 

will provide for enhanced safety, minimize potential for errors, 

enhance training in only one set of harmonized requirements, and 

otherwise minimize costs of maintaining two systems of operations.''

    These and other general changes discussed below will result in 

PHMSA harmonizing with the ICAO Technical Instructions in regards to 

the information required to be provided in the information to the 

pilot-in-command.

     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 flight 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 pilot-in-command. Harmonizing with the ICAO Technical 

Instructions and requiring flight dispatchers to have the same 

information as the pilot-in-command regarding the nature, amounts, and 

locations of hazardous materials improves information sharing in an 

emergency situation. Incorporating this provision into the HMR is also 

relevant to the National Transportation Safety Board's (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

[[Page 52881]]

emergency response or search and rescue is activated.'' \7\

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

    \7\ See http://www.ntsb.gov/safety/safety-recs/recletters/A-11-039-047.pdf.

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

    Consistent with the ICAO Technical Instructions, operators are 

responsible to specify the personnel to be provided the information to 

the pilot-in-command in their operations manual and/or other 

appropriate manuals. The term ``provided'' covers the information to 

the pilot-in-command when made available in a handwritten, printed, or 

electronic format.

    Providing an additional and potentially quicker means for airport 

rescue and firefighting (ARFF) personnel to receive the information to 

the pilot-in-command underscores that the ARFF community is as much an 

intended consumer of the information as is the pilot-in-command. ARFF 

training in hazardous materials incidents is required under 14 CFR part 

139, which specifies the FAA's requirements for certificated airports.

    PHMSA received comments from A4A, COSTHA, and UPS concerning use of 

the term ``written'' in the proposed paragraphs Sec.  175.33(a) and 

(b)(2). A4A and COSTHA commented that the ``accurate and legible 

written information'' language in proposed Sec.  175.33(a) and the 

``copy of the written notification'' language in proposed Sec.  

175.33(b)(2) do not support electronic notification method as air 

operators continue to move away from paper documents towards electronic 

systems for messaging and direct information upload to, and retrieval 

from, the cockpit. In their comments, A4A stated, ``Electronic storage 

and messaging allows the most up-to-date and accurate documentation to 

be retrieved by flight crews, dispatchers and ground personnel at any 

time, providing a safety enhancement in addition to considerable cost 

and environmental benefits.'' UPS commented that including the 

``legible written'' language in the proposed Sec.  175.33(a) allows for 

the interpretation that a printed information to the pilot-in-command 

is required for issuance to the pilot-in-command, as well as having the 

unintended effect of requiring printed information to be furnished to a 

flight dispatcher or equivalent operator employee. UPS explained that 

large carrier operations such as theirs would face difficulties as 

``information is readily available in other formats and the task of 

managing printed copies would be inefficient and contrary to 

technological advances.'' The three commenters provided similar 

alternative language removing the word ``written'' from paragraphs (a) 

and (b)(2).

    The intent of the NPRM was to more closely align the information to 

the pilot-in-command provisions in the HMR with those in the ICAO 

Technical Instructions. Consistent with the language in the NPRM, the 

current requirements in both regulations require that the operator of 

the aircraft provide the pilot-in-command with ``accurate and legible 

written information.'' Chapter 7;4.1.1 b) of the ICAO Technical 

Instructions requires that the aircraft operator provide personnel with 

responsibilities for operation control of the aircraft (e.g., flight 

dispatcher) with the same information required to be provided to the 

pilot-in-command. The ICAO requirement is followed by an example 

indicating that an operator may satisfy this requirement by providing 

the flight dispatcher with a copy of the written information provided 

to the pilot-in-command. However, the requirement in the ICAO Technical 

Instructions, while using the phrase ``copy of the written 

information'' as an example, does not specify the format or method in 

which the information is provided to the flight dispatcher, but rather 

only that the information is the same as provided to the pilot-in-

command.

    PHMSA agrees that the term ``written'' may not be clear to everyone 

that the use of an electronic format for the information to the pilot-

in-command is allowed. Based on the information provided by the three 

commenters, this final rule revises paragraphs (a) and (b)(2) to 

clarify that for the purposes of Sec.  175.33, ``written'' means in a 

handwritten, printed, or an electronic format. Therefore, the 

information provided to both the pilot-in-command and the flight 

dispatcher may be provided legibly in writing (e.g. handwritten, 

printed, or electronic format) provided all requirements of the section 

are met. We recognize the trend of providing the pilot-in-command and 

flight dispatchers with operational data through electronic means and 

that the use of electronic means to supplement the pilot-in-command 

with information about cargo, including hazardous materials, is 

consistent with current practices. The FAA recognizes that there are 

multiple electronic means that operators may use to provide information 

to their pilot-in-command and flight dispatchers.

     Requirement that the information to the pilot-in-command 

be provided to the pilot and flight dispatchers prior to an aircraft 

moving under its own power. The current HMR require the pilot-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 Technical Instructions, PHMSA believes that 

this information should be provided to both the pilot-in-command and 

flight dispatchers prior to the aircraft moving under its own power. 

The pilot-in-command should not be burdened with additional information 

or processes during taxiing and final preparations for takeoff. This 

change would also allow the pilot-in-command additional time to address 

any safety concerns identified after a review of the information before 

taxiing. For example, the pilot-in-command will be more likely to have 

the opportunity to physically inspect (e.g., packages, paperwork, 

etc.), ask questions, or otherwise act on the information if they 

receive the information prior to the aircraft moving.

     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 information 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 information to the pilot-

in-command for 90 days, but there is no requirement for the pilot-in-

command to indicate receipt of the information. To be consistent with 

the ICAO Technical Instructions, PHMSA is requiring the operator to 

obtain and retain documentation of the pilot-in-command's receipt of 

the information.

     Requirement for the information provided to the pilot-in-

command to have 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. The requirement for the information provided to the pilot-in-

command to have a signed confirmation or other indication from the 

person responsible for loading ensures 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 which provides for a more 

accountable safety system.

     General harmonization with the ICAO Technical Instructions 

in regards to information required to be provided in the information to 

the pilot-in-

[[Page 52882]]

command 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 information to 

the pilot-in-command. 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 

aligning with the ICAO Technical Instructions, PHMSA believes that the 

removal of additional description requirements from the information to 

the pilot-in-command will result in decreased complexity and training 

costs for operators without negatively impacting safety. In the NPRM, 

we invited comment from the ARFF community pertaining to the effect 

this proposed rule would have had on past incident or accident 

responses; however, as no comments were received, we are removing the 

additional description requirements from the information to the pilot-

in-command requirements as proposed.

    The current HMR contain a requirement that the information to the 

pilot-in-command prepared in accordance with the ICAO Technical 

Instructions 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 is removing the 

requirement for the information to the pilot-in-command made in 

accordance with the ICAO Technical Instructions to include these 

additional elements. This information will still be required on 

shipping papers.

    General harmonization between the HMR information to the pilot-in-

command requirements and those found in the ICAO Technical Instructions 

ensures consistency for operators subject to both regulatory systems, 

thus reducing the cost of complying with two different sets of 

standards. However, the HMR will continue to require that the date of 

the flight be included on the information to the pilot-in-command, 

while the current ICAO Technical Instructions do not. Maintaining the 

flight date adds another safety control to ensure the pilot-in-command 

has the correct form. As many operators already include the date as a 

part of their information provided to the pilot-in-command, this 

amendment will not create an undue administrative burden. PHMSA 

received one comment from UPS providing support for maintaining the 

flight date on the information to the pilot-in-command. The ICAO 

Dangerous Goods Panel (DGP) took action in October 2016 to amend the 

ICAO Technical Instructions to include the flight date as one of the 

required fields on the information to the pilot-in-command. This change 

will align with the HMR and is expected to be reflected in the 2019-

2020 ICAO Technical Instructions.

    In the NPRM, PHMSA proposed maintaining the existing requirement 

that a hazardous material carried under the terms of a special permit 

must be indicated on the information to the pilot-in-command. PHMSA 

received a comment from UPS stating that the existing term ``special 

permit'' is too focused on U.S. regulations. They note that parallel 

ICAO provision, in Part 7; Section 4.1.1.1 j) refers to a requirement 

to include, ``where applicable, an indication that the dangerous goods 

are being carried under a State exemption.'' UPS suggested that the 

proposed language should be broadened to include a reference to an 

``equivalent document issued by the appropriate authority of another 

country,'' thereby reducing potential variation from the ICAO 

requirement. PHMSA agrees. Therefore, consistent with the ICAO 

Technical Instructions, this final rule adds ``or under a State 

exemption as prescribed in the ICAO Technical Instructions'' in 

addition to ``special permit.'' ICAO defines ``exemption'' as being 

equivalent to a special permit under the HMR. An ``exemption'' does not 

include approvals, which are not required to be indicated on the 

information to the pilot-in-command.

    In their comments, A4A and COSTHA stated that carriers do not 

prepare the information to the pilot-in-command when the hazardous 

material does not require a shipping paper, noting that the HMR do not 

require a shipping paper for lithium cells or batteries prepared in 

accordance with Sec.  173.185(c) or the corresponding Section II of 

ICAO Packing Instructions (PI) 965-970. The commenters noted that part 

7;4.1.11, Table 7-9 provides a list of dangerous goods not required to 

appear in the information to the pilot-in-command. The list includes 

entries for lithium batteries consigned under the entries UN3090, 

UN3091, UN3480, and UN3481 when meeting the requirements of Section II 

of PI 965-970. The commenters noted that the HMR do not have a 

corresponding exception for these same materials prepared even though a 

shipping paper is not required. Both commenters suggested incorporating 

the ICAO provisions by either adding Table 7-9 into Sec.  175.33 or by 

adding a specific exception stating that lithium batteries prepared in 

accordance with Sec.  173.185(c) are not required to appear on the 

information to the pilot-in-command. COSTHA suggested adding exceptions 

in Sec.  175.33 for all materials listed in Table 7-9 of the ICAO 

Technical Instructions such as excepted quantities and ``UN3373 and 

Biological substance, Category B'' among others.

    PHMSA agrees that in instances when a shipping paper is not 

required, the information for that material is generally not required 

to appear on the information to the pilot-in-command either. Because a 

shipping paper contains the information from which the elements of the 

information to the pilot-in-command are derived, it is impracticable to 

prepare the information for materials not requiring a shipping paper. 

We also agree that the HMR do not have a clear exception from the 

information to the pilot-in-command requirement for lithium batteries 

prepared in accordance with Sec.  173.185(c), which corresponds with 

Section II of ICAO PI 965-970. Other materials listed in Table 7-9, 

such as those offered in excepted quantities (Sec.  173.4a), and 

``UN3373 and Biological substance, Category B'' (Sec.  173.199) are 

sufficiently addressed in their relevant section of the HMR, with an 

indication that the materials are not otherwise subject to the 

requirements of the subchapter, to include the requirements of Sec.  

175.33, if the applicable conditions are met. Therefore, this final 

rule clarifies in Sec.  175.33(a)(13) that lithium batteries prepared 

in accordance with Sec.  173.185(c) are not required to appear on the 

information to the pilot-in-command, which corresponds with Section II 

of the applicable ICAO packing instruction.

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

[[Page 52883]]

containing hazardous materials from being transported on an aircraft if 

it has holes. See P-1671.\8\ The petitioner noted that operators 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, operators and freight forwarders declined to transport them 

on the basis of Sec.  175.30(c)(1).

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

    \8\ See https://www.regulations.gov/docket?D=PHMSA-2015-0281.

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

    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 the NPRM, consistent with the ICAO Technical 

Instructions, PHMSA proposed to amend Sec.  175.30(c)(1) to remove 

language prohibiting packages 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.

    PHMSA received comments from A4A, COSTHA, DGAC, and UPS in response 

to the proposed revision. The DGAC commented in support of the proposed 

revision as it enhances harmonization and does not compromise safety. 

UPS commented in support of the proposed revision, noting that the risk 

of transporting such packages aboard aircraft would not be elevated, 

and was also supportive of the NPRM preamble language, stating 

operators are ultimately responsible for the decision to accept such a 

package for transportation. In their comments, A4A and COSTHA provided 

support for the NPRM preamble language, stating that operators may 

continue to have more restrictive standards as a part of their business 

practice; however, they expressed concern on how package integrity 

determinations are to be made and whether enforcement officials will 

accept the aircraft operator's conclusion. COSTHA also commented that 

aircraft operators receive ``knowing'' or ``constructive knowledge'' 

violations for non-compliance with the HMR, further noting that 

accidental damage is not a ``knowing'' violation but that an operator 

accepting a package with a small hole or abrasion could be considered a 

``knowing'' violation as operators are prohibited from transporting 

damaged packages aboard aircraft.

    PHMSA expects that the majority of determinations applicable to 

small holes on the integrity of a package or overpack will be quite 

evident. If an air operator has any doubt on whether the integrity of 

the package or overpack has been compromised, and potentially is not 

suitable for transportation aboard aircraft, it should not be accepted 

for transport in its present condition. Further, a package or overpack 

containing only superficial damage not affecting the integrity, and not 

prohibited by Sec.  175.30(c)(1), would not be considered a damaged 

package or overpack.

    As stated in the NPRM, PHMSA believes the current restriction 

prohibiting acceptance of any package or overpack 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. Therefore, this final rule 

adopts the revision to Sec.  175.30 as proposed in the December 5, 2016 

NPRM with minor editorial clarifications. In reviewing the section 

during development of the final rule, PHMSA determined that the term 

``outside container'' is not applicable. As per the definition of 

``strong outer packaging'' in Sec.  171.8, it is synonymous with 

``strong outer container''. Therefore ``outside container'' has the 

same meaning as outer packaging. Outer packaging is a component of a 

package, which is already listed. As a result, in this final rule PHMSA 

is removing ``outside container'' from paragraphs (b) and (c). In 

addition, in the NPRM, PHMSA proposed to include ``freight container'' 

and ``unit load device'' in the list of containment devices contained 

in paragraph (c). The intent was to align with the provisions in ICAO 

Technical Instructions, but further review found that there is no such 

provision in the ICAO Technical Instructions. In Part 7;1.3.1 i) of the 

ICAO Technical Instructions there is a requirement to verify freight 

containers and unit load devices are not leaking and there is no 

indication that the integrity has been compromised; however, this is 

under the activity of conducting an acceptance checklist which the HMR 

do not require. As a result, in this final rule, we are not listing 

``freight containers'' or ``unit load devices'' in paragraph (c).

    Section 175.88 prescribes requirements for inspection, orientation, 

and securing packages of hazardous materials aboard aircraft. In the 

NPRM, PHMSA proposed 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, 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 Technical Instructions. 

Specifically, PHMSA proposed to revise Sec.  175.88(c) by separating 

the provisions of the existing paragraph (c) into new subparagraphs (1) 

and (4), and adding subparagraphs (2) and (3) to align with part 

7;2.4.3 of the ICAO Technical Instructions that reads as follows:

    When dangerous goods subject to the provisions herein are loaded 

in an aircraft, the operator must protect the packages of dangerous 

goods from being damaged, including by the movement of baggage, 

mail, stores or other cargo. Particular attention must be paid to 

the handling of packages during their preparation for transport, the 

type of aircraft on which they are to be carried and the method 

required to load that aircraft, so that accidental damage is not 

caused through dragging or mishandling of the packages.

    PHMSA received three comments from A4A, COSTHA, and UPS in response 

to the proposed revisions. The commenters stated that the manner in 

which the proposed paragraphs are structured may have the unintended 

effect of applying to activities outside of the aircraft loading 

process, resulting in subjective conditions that could lead to 

inappropriate enforcement. COSTHA commented that the proposed 

requirements ``could be interpreted to prohibit industry standard 

processing and movement of packages and baggage at sorting facilities 

or conveyor belt operations used to move packages.'' A4A and UPS 

commented on the use of ``dragging'' in proposed paragraph (c)(3). A4A 

asserted that normal cargo handling practices could be ``construed by 

an inspector'' as ``dragging'' or inadequate protection resulting in a 

violation and that ``such practices include loading of unit load 

devices and the holds of narrow-body, non-containerized aircraft by 

leveraging smooth floor surfaces to slide packages into place.'' UPS 

commented that the established industry practice of sliding of packages 

on surfaces (e.g., tables, conveyor belts, floors and other surfaces) 

may be subject to proposed language in Sec.  175.88(c)(3), noting that 

the term ``dragging'' would introduce a basis for enforcement personnel 

to misinterpret industry package handling methods. UPS further 

commented that there are aircraft holds, such as those with low 

ceilings, in which the positioning of or removal of packages

[[Page 52884]]

necessitates the sliding or dragging of such packages.

    In addition, the commenters suggested that the proposed text is 

unnecessary because other requirements in the HMR, such as those in 

Sec. Sec.  175.30 and 175.90(c), already prevent the loading of damaged 

packages containing hazardous materials aboard aircraft.

    The intent of the revisions to Sec.  175.88(c) is to ensure that 

hazardous materials are not loaded in an inappropriate manner and that 

accidental damage is not caused during the loading process. The safety 

gap addressed in this final rule covers the movement of hazardous 

materials during the aircraft loading process until the cargo is 

secured aboard the aircraft. PHMSA acknowledges that certain aircraft 

types or configurations necessitate sliding or dragging to position the 

cargo aboard the aircraft. An example of this type of aircraft would be 

passenger aircraft, which contain smaller ``lower hold'' cargo 

configurations. These ``lower hold'' configurations are typically 3-4 

feet in height, in which operator personnel must get on their knees due 

to the small hold area and items must be maneuvered by pushing, 

pulling, and sliding cargo.

    PHMSA has reviewed the existing requirements in Sec.  175.88(c), 

and while these requirements ensure that packages are inspected for 

damage upon initial acceptance by the operator and forbid placing 

aboard an aircraft baggage or cargo that is contaminated with hazardous 

material or appears to be leaking, they do not address accidental 

damage that may be caused through mishandling of the packages during 

the loading process. PHMSA agrees that the paragraph structure could be 

misinterpreted to apply to situations outside of the loading process. 

Therefore, this final rule revises paragraph (c)(3) consistent with the 

language suggested by COSTHA in their comments.

III. Section-by-Section Review

    The following is a section-by-section review of the amendments in 

this final rule:

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. In this final rule, PHMSA is revising the 

column (7) special provisions.

    Specifically, PHMSA is removing: (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 is 

replacing 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 is revising 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 Technical Instructions 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 \9\ provides additional 

guidance to operators on this issue.

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

    \9\ (SAFO) 15010 Carriage of Spare Lithium Batteries in Carry-on 

and Checked Baggage.

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

Section 175.30

    Section 175.30 prescribes requirements for the inspection and 

acceptance of hazardous materials.

[[Page 52886]]

PHMSA is revising Sec.  175.30(c)(1) to no longer prohibit packages or 

overpacks 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 

or overpack.

Section 175.33

    Section 175.33 establishes requirements for shipping papers and the 

information to the pilot-in-command when hazardous materials are 

transported by aircraft. PHMSA is making revisions to harmonize the 

information to the pilot-in-command requirements in the HMR with those 

found in the ICAO Technical Instructions. Specifically, we are making 

revisions to:

     Align the elements that are required to be provided in the 

information to the pilot-in-command;

     Clarify that information to the pilot-in-command may be in 

an electronic form;

     Ensure the information to the pilot-in-command is provided 

to flight dispatchers or, when flight dispatchers are not utilized, 

other ground support personnel with operational control of the 

aircraft;

     Harmonize with ICAO requirements addressing when the 

information must be provided to the pilot-in-command and flight 

dispatchers;

     Require confirmation via signature or other appropriate 

indication by the pilot-in-command to indicate that the required 

information was received;

     Clarify that UN3480, UN3481, UN3090, and UN3091 prepared 

in accordance with Sec.  173.185(c), except Sec.  173.185(c)(4)(vi), 

are not required to appear on the information to the pilot-in-command; 

and

     Require that the information provided to the pilot-in-

command contain 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.

    Consistent with the ICAO Technical Instructions, we are also 

amending 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.

    PHMSA has restructured Sec.  175.33 to separate the requirements 

for the information to the pilot-in-command from those for shipping 

papers to address comments to the NPRM from UPS stating that the 

proposed text is confusing and suggesting revisions to improve clarity.

Section 175.88

    Section 175.88 prescribes requirements for inspection, orientation, 

and securing packages of hazardous materials aboard aircraft. PHMSA is 

amending Sec.  175.88(c) by separating the provisions of the existing 

paragraph (c) into new subparagraphs (1) and (4), and adding 

subparagraphs (2) and (3) to align with part 7;2.4.3 of the ICAO 

Technical Instructions. Specifically, these new paragraphs will require 

that hazardous materials be: (1) Secured in an aircraft in a manner 

that will prevent any change in the orientation of the packages; (2) 

protected from damage, including by the movement of baggage, mail, 

stores, or other cargo; (3) loaded so that accidental damage is not 

caused through dragging or mishandling; and (4) Class 7 (radioactive) 

materials be 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.

IV. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This final 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 final rule amends regulations to increase alignment with 

international standards by incorporating various amendments, including 

changes to special provisions, packaging requirements, air transport 

information to the pilot-in-command requirements, and allowances for 

hazardous materials to be carried on board an aircraft by passengers 

and crewmembers. To this end, this final rule amends regulations to 

more fully align the HMR with the ICAO Technical Instructions. 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. We consulted the FAA 

in the development of this rule.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

    This final rule is not considered a significant regulatory action 

under section 3(f) of Executive Order 12866, ``Regulatory Planning and 

Review,'' 58 FR 51735 (Oct. 4, 1993) and, therefore, was not reviewed 

by the Office of Management and Budget. Accordingly, this final rule is 

not considered a significant rule under the Regulatory Policies and 

Procedures of the Department of Transportation. 44 FR 11034 (Feb. 26, 

1979).

Benefits of the Rule

    PHMSA analyzed the expected benefits of these provisions in this 

final rule. 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 final rule, most of the benefits will be derived from health 

and safety factors, as well as reduced compliance costs.

    The health and safety benefits specifically attributable to 

modifications of the information to the pilot-in-command requirements 

are not easily calculable with any degree of accuracy. The requirements 

for pilot-in-command's signature and confirmation from the person 

responsible for loading the aircraft will result in more effective and 

efficient response in the event of an aviation incident. The 

requirement that packages be protected from damage during loading 

operations will result in increased safety and environmental 

protection. Benefits will also be realized through a more efficient 

response time because of emergency response personnel having quicker 

access to hazardous materials information for each flight.

[[Page 52887]]

Cost Reducing Aspects of Harmonization

    The primary cost savings expected from this final rule 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. Additionally, while they have not been 

quantified, PHMSA expects cost savings from the final rule's general 

harmonization of information to the pilot-in-command requirements and 

support for the use of electronic formats.

    Currently, compliance with special provisions A3 and A6 requires 

domestic shippers to use extra \10\ or more expensive \11\ materials. 

Shippers also incur higher freight charges for shipping packages with 

higher package weights.\12\ 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, will provide 

undiscounted annual cost savings of $1,814,643 in reduced packaging 

costs to shippers.

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

    \10\ A metal container enclosing either a plastic or glass 

container.

    \11\ A metal or glass container rather than a plastic container.

    \12\ 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 these cost savings, 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 requirements in this final 

rule.

    A summary of the cost savings calculation method is as follows. 

PHMSA estimated the cost savings by comparing the difference in costs 

between the pre- and post-final rule options for each shipping scenario 

identified for commodities potentially subject to A3 or A6. For the 

purposes of this analysis, we assumed that relatively inexpensive 

metal, plastic, and glass packaging could be used for inner and 

intermediate receptacles. There are no costs specifically attributable 

to the A3 compliance requirements because the least cost option for 

shipping is to use metal or plastic containers, and A3 applies to 

shipments in glass containers. While some commodities are shipped in 

glass containers due to various factors (e.g. ensuring product 

composition is maintained, customer demand, or specific retail 

requirements), the analysis assumed that shippers always choose the 

least cost option. We were unable to quantify the number of A3 

shipments that are currently voluntarily offered in glass inner 

packagings. The potential cost savings per package are due to increased 

flexibility posed by the use of any rigid intermediate packaging 

instead of the single metal type currently required.

    PHMSA estimated the compliance costs attributable to A6 compliance 

requirements, which vary by type of shipment and packaging type. For 

example, the difference in the compliance cost for a one-gallon 

shipment using UN specification packaging for materials corrosive to 

metal is estimated at $3.82 for Packing Groups I, II or III. The 

estimated number of tons subject to A6 for UN specification packaging 

(corrosive to metal and PG I) is 641. The number of packages affected 

depends on the average inner receptacle volumes applicable to each 

packing group and restriction type. These calculations assume that the 

density of the chemicals is the same as that of water (i.e., one ton of 

each affected commodity has a volume of 239.65 gallons). Therefore, if 

the number of gallons per package for a commodity corrosive to metal 

and PG I is 0.66, the estimated number of packages per ton for that 

commodity is 363 (239.65/0.66). Thus, the total number of packages is 

232,683 packages = 363 packages/ton multiplied by 641 tons. The total 

annual shipping cost difference is estimated at $889,434 by multiplying 

the cost difference per package noted above of $3.82 by the number of 

affected packages, 232,836. Similarly, PHMSA estimates the annual 

shipping cost difference for UN specification packaging for PG I 

materials not corrosive to metal at $159,150 and the total annual 

shipping cost difference for PG II materials corrosive and not 

corrosive to metal at $766,059. Therefore, the annual shipping cost 

difference for all PGs is estimated at $1,814,643 ($889,434 + $159,150 

+ $766,059).

    The reduced expenditure cost savings associated with the general 

harmonization of the information to the pilot-in-command requirements 

are not easily calculable. 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. Clarifying that the term ``written'' in the information to 

the pilot-in-command applies to handwritten, printed, or electronic 

formats supports the use of electronic methods as air operators 

continue to move away from paper documents and towards electronic 

systems. Cost savings may be realized by utilizing existing messaging 

systems for direct upload of information to and retrieval from, the 

cockpit. In addition, there may be cost savings for operators electing 

to use electronic information methods as they will not have to 

physically print the information for use and retention purposes. PHMSA 

expects the increased harmonization of the HMR and ICAO Technical 

Instructions to generate cost savings by streamlining the processes for 

information to the pilot-in-command generation.

Costs of Harmonization

    The primary costs associated with this final rule are time costs 

related to 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 information to the pilot-in-command 

requirements with those found in the ICAO Technical Instructions to be 

$795,318. This estimate is the total annual costs in 2016 dollars of 

the additional costs for pilot ($465,966) and loader ($106,845) 

acknowledgements plus HMR training costs ($222,507).

    A summary of the annual cost calculation is as follows. PHMSA 

estimates there are between 1,056 and 9,920 projected flights \13\ 

daily carrying hazmat that would be subject to harmonized HMR and ICAO 

information to the pilot-in-command requirements with a mean daily 

value of 5,415 (1,976,475 annual). The estimated pilot acknowledgement 

cost of $0.24\14\ (based on average pilot salary and five seconds per 

action) per information received by the pilot-in-command multiplied by 

the estimated annual number of associated flights results in a total 

cost of $465,966. Person(s) responsible for loading the aircraft costs 

were calculated in the same manner as pilots but with an estimated

[[Page 52888]]

acknowledgement cost of $0.05 \15\ per information to the pilot-in-

command resulting in an estimated cost of $106,845. Based on FAA air 

operator data, the number of additional employees requiring training is 

estimated at 2,086 at an estimated training cost of $107 per trainee 

per year. The estimated annual expected industry training costs in 2016 

dollars would then be $222,507 = 2,086 employees multiplied by $107 per 

employee. PHMSA notes that many air operators already comply with 

ICAO's information to the pilot-in-command requirements; therefore, it 

is likely that this analysis has overestimated the cost of 

harmonization. The HMR currently require 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 specific confirmation requirement (signature or other 

indication) from the person responsible for loading the aircraft, which 

would already be accounted for in time costs.

affected flights subject to this requirement.

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

    Under current practice, the information is transmitted to the 

pilot-in-command. We assume the additional provision of identical 

information to the flight dispatcher (or other personnel) will incur 

negligible costs, if any, especially as we understand this to be a 

common industry practice. In the NPRM, PHMSA invited comments on this 

assumption and on any unanticipated costs associated with the proposed 

requirement. While PHMSA did not receive any specific comments on 

additional costs associated with providing the same information to the 

flight dispatcher, all of the commenters provided strong support for 

harmonizing with the information to the pilot-in-command provisions of 

the ICAO Technical Instructions.

Net Cost Savings

    Based on the previous discussions of benefits, costs, and cost 

savings PHMSA estimates the net annual cost savings associated with 

this final rule (2137-AF10) to be $1,019,325.

C. Executive Order 13771

    Executive Order 13771 (``Reducing Regulation and Controlling 

Regulatory Costs''), issued January 30, 2017, provides that ``it is 

essential to manage the costs associated with the governmental 

imposition of private expenditures required to comply with Federal 

regulations.'' Toward that end, E.O. 13771 directs agencies to (1) 

identify two potential deregulatory actions for each new E.O. 13771 

regulatory action, and (2) limit the incremental costs of new 

regulations overall on a fiscal year basis. This final rule is 

considered an E.O. 13771 deregulatory action. Details on the estimated 

cost savings of this final rule are described above.

D. Executive Order 13132

    This final rule has been analyzed in accordance with the principles 

and criteria contained in Executive Order 13132, ``Federalism,'' 64 FR 

43255 (Aug. 10, 1999). The regulatory changes in this final rule 

preempt State, local, and Indian tribe requirements but do not have 

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 materials 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, reconditioning, repair, or testing of a packaging or 

container represented, marked, certified, or sold as qualified for use 

in transporting hazardous material in commerce.

    This final 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 final rule is 

necessary to harmonize with international standards. If the 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 rulemaking are intended to avoid this 

result. Federal hazardous materials transportation law provides 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. 49 U.S.C. 5125(b)(2). 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 is setting the effective date of Federal preemption to be 90 days 

from publication of a final rule in this matter.

E. Executive Order 13175

    This final 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 final 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.

F. Regulatory Flexibility Act, Executive Order 13272, and DOT Policies 

and Procedures

    This final 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 economic 

impact on small entities, unless the agency determines that a rule is 

not expected to have a significant economic impact on a substantial 

number of small entities.

    This final 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 final rule will result in cost 

savings and ease the regulatory compliance burden for shippers engaged 

in domestic and international

[[Page 52889]]

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 final rule will 

relieve U.S. companies, including small entities competing in foreign 

markets, from the burden of complying with a dual system of 

regulations. Therefore, we certify that these amendments will not have 

a significant economic impact on a substantial number of small 

entities.

G. Paperwork Reduction Act

    PHMSA currently has an 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 final 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 information to the pilot-in-

command 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. PHMSA did not receive any comments on the changes to this 

information collection burden in response to the NPRM.

    This rulemaking identifies a revised information collection that 

PHMSA will submit to OMB for approval based on the requirements in this 

final rule. PHMSA has developed burden estimates to reflect changes 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.

    Annual Increase in Annual Burden Hours: 5,474.

    Annual Increase in Annual Burden Costs: $572,811.

    PHMSA will submit the revised information collection and 

recordkeeping requirements to OMB for approval.

H. 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 

the Spring and Fall of each year. The RIN contained in the heading of 

this document can be used to cross-reference this action with the 

Unified Agenda.

I. Unfunded Mandates Reform Act

    This final rule does not impose unfunded mandates under the 

Unfunded Mandates Reform Act of 1995. It does not result in costs of 

$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.

J. 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 requires 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 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 final rule, PHMSA is amending the HMR to increase 

harmonization with international standards and to address four 

petitions for rulemaking submitted by shippers, carriers, 

manufacturers, and industry representatives. These revisions are 

intended to harmonize with international standards, while also 

maintaining or enhancing safety. Specifically, PHMSA, consistent with 

P-1487, is harmonizing the HMR with the 2017-2018 ICAO Technical 

Instructions' requirements for the information to the pilot-in-command, 

for the air operator to provide the information to the pilot-in-command 

to the flight dispatcher, and for the air operator to obtain and retain 

a confirmation that the information to the pilot-in-command was 

received by the pilot-in-command. This final rule addresses three 

additional petitions for rulemaking (P-1637, P-1649, and P-1671) to: 

(1) More closely harmonize with the ICAO Technical Instructions 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 metal batteries that exceed the current 

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 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 package or 

overpack has been compromised. All of these amendments more closely 

harmonize U.S. regulations with international standards.

    This action is necessary to: (1) Fulfill PHMSA's statutory 

directive to promote transportation safety; (2) fulfill PHMSA's 

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, 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 are 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.

2. Alternatives

    In developing this rulemaking, PHMSA considered the following 

alternatives:

    No Action Alternative:

    If PHMSA had selected the No Action Alternative, regulations would 

remain in place and no new provisions would be added. However, 

efficiencies gained through harmonization in updates to information to 

the pilot-in-command requirements; intermediate packaging requirements; 

passenger carriage of portable medical electronic devices containing 

certain lithium metal batteries; acceptance/transport of packages with 

small holes that do not compromise the package integrity; ensuring that 

hazardous materials loaded in an aircraft are protected from damage; 

etc., would not be realized.

    Preferred Alternative:

    PHMSA selected the Preferred Alternative. The amendments included 

in this alternative are more fully addressed in the preamble and 

regulatory text sections of this final rule. However, they include the 

following:

[[Page 52890]]

    (1) Harmonize the HMR and ICAO Technical Instructions information 

to the pilot-in-command requirements. In this final rule, PHMSA is more 

closely aligning the information to the pilot-in-command requirements 

in the HMR to the ICAO Technical Instructions. This includes 

information required, when the information must be provided to the 

pilot-in-command and flight dispatchers, and requirements for verifying 

that the information was received by the pilot-in-command.

    (2) More closely harmonize with the ICAO Technical Instructions in 

regard to intermediate packaging requirements for certain low and 

medium danger hazardous materials. In this final rule, PHMSA is 

removing all references to special provision A6 assigned to liquids in 

the Hazardous Materials Table. Additionally, this final rule amends 

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 final rule, PHMSA is amending 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 Technical Instructions allow portable medical 

electronic devices containing lithium metal batteries with 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 

final rule, PHMSA is amending Sec.  175.30(c)(1) to remove language 

prohibiting any package or overpack containing hazardous materials from 

being transported on an aircraft if it has holes. Additionally, PHMSA 

is revising 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 Technical Instructions.

3. Probable Environmental Impacts of the Alternatives

    No Action Alternative:

    If PHMSA had selected the No Action Alternative, regulations would 

remain in place and no new provisions would be added. However, 

efficiencies gained through harmonization of 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 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 environmental and safety requirements 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:

    PHMSA selected the Preferred Alternative. We believe that safety 

and environmental risks will be reduced and that protections to human 

health and environmental resources will be increased. Consistency 

between U.S. and international information to the pilot-in-command 

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 

amendments will reduce inconsistent hazardous materials regulations, 

which can increase the time and cost of compliance training. For ease 

of compliance with appropriate regulations, operators engaged in the 

transportation of hazardous materials generally elect to accept and 

transport hazardous materials in accordance with the ICAO Technical 

Instructions, 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 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 Technical Instructions 

information to the pilot-in-command requirements. Harmonization of 

information to the pilot-in-command requirements will (1) allow 

operators 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 

flight dispatchers access to hazmat information and relieve the pilot-

in-command 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 

amendment.

    (2) More closely harmonize with the ICAO Technical Instructions 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 ICAO's packing instructions 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 

amendment.

    (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 metal battery limits in Sec.  

175.10(a)(18)(i). Harmonizing with the ICAO Technical Instructions in 

this area will assist the traveling public who rely on their portable 

medical electronic devices powered by lithium metal batteries. This 

revision will be consistent with the FAA Modernization and Reform Act.

    Greenhouse gas emissions would remain the same under this 

amendment.

    (4) Amend the package inspection and securing requirements. 

Harmonizing with the ICAO Technical Instructions in this area will 

address the overly prescriptive requirements for package inspection and 

securing, which

[[Page 52891]]

currently result in acceptance rejections from operators and freight 

forwarders. Further, harmonization will result in more targeted and 

effective training and thereby enhanced environmental protection. These 

amendments will reduce inconsistent hazardous materials regulations, 

which hamper compliance training efforts.

    Greenhouse gas emissions would remain the same under this 

amendment.

4. Agencies Consulted

    PHMSA coordinated with the U.S. Federal Aviation Administration, 

the Federal Motor Carrier Safety Administration, the Federal Railroad 

Administration, and the U.S. Coast Guard, in the development of this 

final rule. PHMSA considered 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 final 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 concludes that the 

net environmental impact will be positive and that there are no 

significant environmental impacts associated with this final rule.

K. Privacy Act

    In accordance with 5 U.S.C. 553(c), DOT solicits comments from the 

public to better inform its rulemaking process. DOT posts these 

comments, without edit, including any personal information the 

commenter provides, to www.regulations.gov, as described in the system 

of records notice (DOT/ALL-14 FDMS), which can be reviewed at 

www.dot.gov/privacy.

L. 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. We have 

assessed the effects of this final rule to ensure that it does not 

cause unnecessary obstacles to foreign trade. In fact, the final 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.

M. 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 final 

rule does not involve voluntary consensus standards.

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 crewmembers 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. With the approval of the operator, no more than two 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 the spare batteries are intended to operate;

7. Section 175.33 is revised to read as follows:

Sec.  175.33   Shipping paper and information to the pilot-in-command.

    (a) When a hazardous material subject to the provisions of this 

subchapter is carried in an aircraft, the operator of the aircraft must 

provide the pilot-in-command and the flight dispatcher or other ground 

support personnel with responsibilities for operational control of the 

aircraft with accurate and legible written information (e.g., 

handwritten, printed, or electronic form) 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 date of the flight;

    (2) The air waybill number (when issued);

    (3) The proper shipping name (the technical name(s) shown on the 

shipping paper is not required), hazard class or division, subsidiary 

risk(s) corresponding to a required label(s), packing group and 

identification number of the material 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.

    (4) The total number of packages;

    (5) The exact loading location of the packages;

    (6) The net quantity or gross mass, 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;

    (7) For Class 7 (radioactive) materials, the number of packages 

overpacks or freight containers, their category, transport index (if 

applicable), and their exact loading location;

    (8) Confirmation that the package must be carried on cargo-only 

aircraft;

    (9) The airport at which the package(s) is to be unloaded;
