IV. Discussion of Amendments and Applicable Comments

    Based on an assessment of the 24 petitions and the comments 
received, PHMSA is amending the HMR as detailed in this section.

1. Phase-Out of Non-Normalized Tank Cars Used To Transport PIH 
Materials

    In its petition (P-1646), the Association of American Railroads 
(AAR) requests that PHMSA consider an amendment to Sec.  173.31 to 
codify a prohibition on the use of rail tank cars with shells or heads 
constructed of non-normalized steel for transportation of PIH 
materials.\6\ In P-1646, AAR claims that the continued use of 
pressurized tank cars constructed from non-normalized steel for rail 
transportation of PIH materials poses an unnecessary risk to the public 
because at lower temperatures non-normalized steel is susceptible to 
brittle fractures, which are far more likely to result in a 
catastrophic failure and instantaneous release of a tank car's entire 
contents than ductile fractures. AAR notes that while a slow release of 
contents generally has time to dissipate in the atmosphere, an 
instantaneous release from a catastrophic failure creates a 
concentrated toxic cloud with potential catastrophic consequences for 
the nearby population.
---------------------------------------------------------------------------

    \6\ PHMSA notes that petition P-1646 (codifying an industry 
phase-out of legacy tank cars with non-normalized steel for PIH 
service by December 31, 2020) is related to two other AAR petitions 
addressed in this final rule: P-1691 (re-designating the ``interim'' 
HM-246 standard for PIH tank cars as a ``permanent'' standard), and 
P-1692 (codifying an industry phase-out of legacy tank cars not 
built to the HM-246 standard for PIH service by December 31, 2027). 
See Sections IV.13 (Finalization of the HM-246 Tank Car Standard) 
and IV.14 (Phase-out of Non-HM-246 Compliant Rail Tank Cars).
---------------------------------------------------------------------------

    PHMSA agrees with AAR's safety rationale for its recommendation of 
a regulatory prohibition on the use of rail tank cars with shells or 
heads constructed of non-normalized steel for transportation of PIH 
materials. Further, PHMSA expects that a regulatory phase-out of these 
rail tank cars would reinforce the voluntary phase-out of legacy PIH 
tank cars pursuant to current industry efforts. In 2008, PHMSA 
considered mandating a 5-year phase-out of non-normalized steel tank 
cars in

[[Page 75683]]

PIH service.\7\ However, in 2009, based in part on statements from 
owners that they were voluntarily phasing out such tank cars, PHMSA 
declined to require the phase-out but did require that owners 
prioritize replacement of the non-normalized steel tank cars from their 
PIH fleets.\8\ Those voluntary efforts have been memorialized in 
interchange rules issued by AAR requiring compliance with design 
standards or operating conditions as a condition of shipping hazardous 
materials by rail. On April 7, 2017, AAR adopted an interchange rule in 
Casualty Prevention Circular (CPC)-1325 \9\ that implemented a phase-
out of these non-normalized (legacy) steel tank cars in PIH service by 
July 1, 2019. On July 27, 2018, AAR revised CPC-1325 and re-issued it 
as CPC-1336, but retained the phase-out deadline for the non-normalized 
steel tank cars,\10\ effective July 1, 2019. Because AAR has already 
adopted a phase-out schedule, there are no additional costs associated 
with PHMSA implementing a December 31, 2020, date as a regulatory 
deadline. A more detailed discussion of this economic analysis can be 
found in the accompanying Regulatory Impact Analysis (RIA).
---------------------------------------------------------------------------

    \7\ See 73 FR 17817 (April 1, 2008).
    \8\ 74 FR 1770 (Jan. 13, 2009).
    \9\ CPCs are documents issued by AAR to its members outlining 
requirements for the transportation of hazardous materials by rail.
    \10\ A piece of rail equipment, such as a tank car, that does 
not meet AAR interchange standards is effectively prohibited from 
movement on the U.S., Canadian, and Mexican freight rail system. The 
AAR Tank Car Committee (TCC) initially developed a phase-out 
schedule for non-normalized tank cars in 2008 under AAR CPC-1187, 
which prohibited the use of non-normalized tank cars after December 
31, 2018. Prior to adoption of the final AAR interchange phase-out 
requirements in CPC-1325, AAR TCC solicited comments to amend CPC-
1187 via CPC-1324.
---------------------------------------------------------------------------

    PHMSA received comments from AAR, the Chemours Company (Chemours), 
and a joint comment from the American Chemistry Council (ACC), the 
Chlorine Institute (CI), and The Fertilizer Institute (TFI) in support 
of the proposal to amend the HMR to include a regulatory phase-out of 
the use of pressurized tank cars constructed from non-normalized steel 
for rail transportation of PIH materials. These associations represent 
major stakeholders impacted by this change, including the shippers who 
own or lease the tank cars, and may bear the cost of implementing any 
phase-out, and the railroads who must transport the freight under their 
obligations as common carriers. PHMSA's actions to align the HMR with 
industry's voluntary phase-out the use of non-normalized (legacy) steel 
tank cars in PIH service in this final rule provide both shippers and 
carriers with regulatory certainty on the transportation of PIH 
materials by rail. This regulatory certainty makes transportation cost 
known to industry and, more importantly, locks-in within the HMR safety 
benefits from the transportation of PIH materials by rail achieved by 
industry's voluntary efforts to phasing-out the use of tank cars with 
shells or heads constructed of non-normalized steel.
    Therefore, in this final rule, PHMSA is revising Sec.  173.31 to 
provide for a regulatory phase-out non-normalized steel rail tank cars 
for the transportation of PIH materials by December 31, 2020.

2. Limited Quantity Shipments of Hydrogen Peroxide

    In its petition (P-1658), Steris requests that PHMSA revise Column 
(8A) of the HMT to make available the limited quantity packaging 
exceptions at Sec.  173.152 for ``UN2014, Hydrogen peroxide aqueous 
solution.'' Steris notes that the United Nations (UN) Recommendations 
on the Transport of Dangerous Goods: Model Regulations (Model 
Regulations) authorize shipment of limited quantities of UN2014 
(Hydrogen peroxide). Steris contends that this amendment would provide 
economic and logistical consistency in global transportation and 
facilitate commerce for domestic companies without adversely impacting 
safety. PHMSA received no comments on this proposed revision in the 
NPRM.
    The HMR at subpart D of part 173 provides, among other provisions, 
exceptions for some classes of hazardous materials when shipped under 
certain limited quantity thresholds. However, while other international 
standards and regulations, such as the UN Model Regulations, provide 
for the transport of UN2014 in limited quantities (up to 60 percent 
concentration), UN2014 is not authorized a limited quantity exception 
within the HMR as currently written. PHMSA has considered the 
operational experience in international transportation of UN2014 
pursuant to the UN Model Regulations as well as in the domestic 
transport of materials of the same hazard class in limited quantities 
as allowed by current HMR exceptions and concluded that a limited 
quantity exception should be extended to UN2014 as well. PHMSA is 
unaware of any characteristics of UN2014 (Hydrogen peroxide) making it 
uniquely unsuitable for limited quantity shipment when other hazardous 
materials assigned the same hazard class can be shipped in limited 
quantities. Consequently, PHMSA expects that expanding the 
applicability of the limited quantity exception to this material will 
not adversely affect safety--particularly as other HMR requirements 
would still apply to assure safe shipment of limited quantities of 
UN2014 (Hydrogen peroxide). PHMSA expects cost savings to be achieved 
from this amendment to the HMR, as extension of the limited quantity 
exceptions to apply to another material will reduce regulatory burdens 
on regulated entities. However, since limited quantity shipments within 
the United States have not been authorized for UN2014 (Hydrogen 
peroxide) previously, there is inadequate domestic data available to 
quantify the specific cost savings that would result from this change. 
A more detailed discussion of the economic analysis can be found in the 
accompanying RIA.
    Therefore, in this final rule, PHMSA is revising Column (8A) of the 
HMT for ``UN2014, Hydrogen peroxide aqueous solution'' to allow limited 
quantity packaging for this material by referencing the exception in 
Sec.  173.152.

3. Markings on Portable Tanks

    In his petition (P-1666), William J. Briner requests that PHMSA 
revise Sec.  172.302(b)(2) of the HMR consistent with section 5.3.2.0.2 
of the IMDG Code to allow a minimum height of 12 mm (0.47 inches) for 
proper shipping name markings on portable tanks with a capacity of less 
than 3,785 L (1,000 gallons). The petitioner contends that the revision 
would provide regulatory flexibility for the size of markings on 
portable tanks without adversely impacting safety. PHMSA received no 
comments on this proposed revision in the NPRM.
    As currently codified in the HMR, Sec.  172.302(b)(2) requires 
markings on portable tanks with capacity less than 3,785 L (1,000 
gallons) to have a width of at least 4.0 mm (0.16 inch) and a height of 
at least 25 mm (1 inch). Through its technical review of this petition, 
PHMSA determined that harmonizing the height of this marking with that 
in the IMDG Code (12 mm) would not cause a reduction in hazard 
communication and, therefore, would not have a negative effect on 
safety. PHMSA expects that harmonizing this requirement with 
international standards would provide cost savings and efficiencies in 
transportation; however, PHMSA is unable to quantify these potential 
cost savings as there is no cost data on the savings gained from using 
smaller markings and the number of stakeholders affected. A more 
detailed discussion of the economic

[[Page 75684]]

analysis can be found in the accompanying RIA.
    Therefore, in this final rule, PHMSA is revising Sec.  
172.302(b)(2) to allow a minimum height of 12 mm (0.47 inches) for 
proper shipping name markings on portable tanks with a capacity of less 
than 3,785 L (1,000 gallons).

4. Reconditioning of Metal Drums

    In its petition (P-1670), the Reusable Industrial Packaging 
Association (RIPA) requests that PHMSA revise Sec.  173.28(c)(1)(i) to 
require that labels be substantially removed, rather than completely 
removed, during the reconditioning of metal drums. RIPA states that a 
strict reading of the current HMR requirement asks for an impossible 
standard, as the full removal of coatings and labels (including their 
adhesive residues) is practically impossible. RIPA justifies this 
request by noting that current cleaning and surface preparation 
processes have been utilized for decades and, from its standpoint, have 
never been considered a safety issue.
    In the NPRM, PHMSA responded to P-1670 by proposing to allow 
tightly adhering paint, mill scale, and rust to remain on no more than 
10 percent of the surface area of a drum being reconditioned. While 
supportive of revising this section, RIPA notes in its comments to the 
NPRM that the proposed revision fails to achieve PHMSA's goal of 
allowing some coating residue to remain on steel drums provided safety 
is not compromised. RIPA contends it is technically impossible to meet 
a requirement that entails the removal of 90 percent of ``tightly 
adhering paint . . .'' from the entire surface area of every steel drum 
and contends that the limit of 10 percent surface area for exterior 
coatings is arbitrary and will be difficult to enforce. Lastly, RIPA 
notes that mill scale does not appear on metal used to manufacture or 
recondition steel drums and should be removed from the proposed 
revisions to Sec.  173.28(c)(1)(i). Therefore, in its comments to the 
NPRM, RIPA suggests that Sec.  173.28(c)(1)(i) be revised to read, 
``Cleaning to base material of construction, with all former contents, 
internal and external corrosion removed, and any external coatings and 
labels sufficiently removed to expose any metal deterioration which 
adversely affects transportation safety.'' RIPA contends this will 
establish a workable safety standard based upon adequate removal of 
surface coating materials to expose evidence of metal deterioration. 
PHMSA received no other comments on this proposed change to the HMR.
    After further consideration, PHMSA agrees that identifying a 
specific numeric threshold for sufficient removal of coatings and 
labels to expose deterioration is impracticable and expects that the 
language RIPA suggests in its comments to the NPRM will appropriately 
address the issue by ensuring external coatings and labels are 
sufficiently removed to expose metal deterioration that could adversely 
impact transportation safety. Furthermore, PHMSA expects cost savings 
to be achieved through this amendment, as it provides for a partial 
relaxation of the requirements in the HMR; however, PHMSA is unable to 
quantify these potential cost savings because it does not have data on 
the cost differences between ``removed'' and ``substantially removed'' 
or the number of persons affected. A more detailed discussion of the 
economic analysis can be found in the accompanying RIA.
    Therefore, in this final rule, PHMSA is revising Sec.  
173.28(c)(1)(i) to read, ``Cleaning to base material of construction, 
with all former contents, internal and external corrosion removed, and 
any external coatings and labels sufficiently removed to expose any 
metal deterioration that adversely affects transportation safety.''

5. Limited Quantity Harmonization

    In its petition (P-1676), URS Corporation requests that PHMSA 
revise Column (8A) of the HMT to extend exceptions allowing for 
shipment of limited quantities of 45 additional hazardous materials. 
URS Corporation noted that the absence from the HMR of limited quantity 
exceptions for those materials is inconsistent with provisions under 
various international standards authorizing limited quantity shipment 
of the same materials. URS Corporation contends that this inconsistency 
between domestic and international standards regarding the limited 
quantity exception for these 45 proper shipping names causes confusion 
regarding the pertinent regulatory requirements with importing 
hazardous materials shipments into the United States that had been 
prepared as limited quantity shipments under international regulations.
    As noted in the NPRM, PHMSA conducted a technical review of the 
petition and identified a total of 114 entries in the HMT--including 
the 45 listed in URS Corporation's petition--that are not in alignment 
with the UN Model Regulations permitting limited quantity shipment of 
hazardous materials. In addition, PHMSA determined that HMR treatment 
of 64 of those 114 entries also diverged from the International Civil 
Aviation Organization Technical Instructions for the Safe Transport of 
Dangerous Goods (ICAO Technical Instructions) permitting limited 
quantity shipment of hazardous materials. Further, in reviewing the 
HMR, PHMSA determined that these hazardous materials currently without 
limited quantity exceptions are of the same hazard classes as materials 
for which the HMR already contains an exception allowing limited 
quantity shipment.
    PHMSA expects that expanding the applicability of the limited 
quantity exception to these additional materials would not adversely 
affect safety. PHMSA is unaware of any characteristics of the hazardous 
materials at issue that makes them uniquely unsuitable for limited 
quantity shipment when the HMR authorizes other hazardous materials 
assigned the same hazard class to be shipped in limited quantities. 
Consequently, PHMSA expects that expanding the applicability of the 
limited quantity exception to other materials that are within the same 
hazard class will not adversely affect safety--particularly as other 
HMR requirements would still apply to assure safe shipment of limited 
quantities of those materials. By way of example, limited quantities of 
these hazardous materials will still need to display a conspicuous 
marking indicating they are limited quantity shipments pursuant to 
Sec.  172.315, and will still need to be packaged in accordance with 
other requirements in 49 CFR part 173. The operational experience of 
safe transportation of limited quantities of these materials pursuant 
to UN Model Regulations provides additional evidence that extension of 
the HMR's limited quantity exceptions to those materials will not 
adversely affect safety. Furthermore, PHMSA expects cost savings to be 
achieved through this amendment, as it provides exceptions to the 
requirements in the HMR that impose compliance burdens on regulated 
entities; however, due to a lack of domestic data on these types of 
shipments, PHMSA is unable to quantify the specific cost savings that 
would result from this change. A more detailed discussion of the 
economic analysis can be found in the accompanying RIA.
    The Council on Safe Transportation of Hazardous Articles (COSTHA) 
and International Vessel Operators Dangerous Goods Association (IVODGA) 
submitted comments to the NPRM in support of this proposed revision, 
while also noting that PHMSA overlooked one listing in the HMT for 
harmonization. The commenters explain that the HMT

[[Page 75685]]

listing for ``UN3170, Aluminum smelting by-products or Aluminum 
remelting by-products'' includes a change in Column (8A) from ``None'' 
to ``151'' for Packing Group (PG) II but failed to revise the PG III 
entry. PHMSA acknowledges that this was an oversight and is revising 
the language in the HMT to include ``UN3170, Aluminum smelting by-
products or Aluminum remelting by-products'' PG III materials in this 
final rule.
    Therefore, in this final rule, PHMSA is revising Column (8A) 
(exceptions) of the HMT consistent with the UN Model Regulations to 
allow an additional 114 hazardous materials entries to be shipped as 
limited quantities under the HMR. The complete list of hazardous 
materials affected by this provision is in the amendments to the HMT at 
the end of this final rule.

6. Mobile Refrigeration Units

    In its petition (P-1677), the International Institute of Ammonia 
Refrigeration (IIAR) requests that PHMSA revise Sec.  173.5b to allow 
the continued use of mobile refrigeration units (which are commonly 
used by the U.S. produce industry) that were placed into service prior 
to 1991, provided they are tested to a service pressure of 250 psig. 
PHMSA received no comments on this proposed revision in the NPRM.
    As currently written, Sec.  173.5b(b)(6) of the HMR requires that 
mobile refrigeration systems placed into service prior to June 1, 1991 
be phased-out by October 1, 2017; however, PHMSA issued an enforcement 
discretion memorandum \11\ on September 28, 2017, permitting the 
continued use of mobile refrigeration units that are tested to a 
service pressure of 250 psig. In its technical review conducted in 
connection with the Enforcement Discretion Memorandum, PHMSA determined 
there is no reduction in safety by authorizing the continued use of 
mobile refrigeration units that are tested to a service pressure of 250 
psig because the purpose of Sec.  173.5b is to eliminate the use of 
systems with a maximum allowable working pressure (MAWP) of 150 psig. 
PHMSA consequently incorporated that conservatism within the 
Enforcement Discretion Memorandum in the proposed HMR amendments set 
forth in the NPRM. The proposed amendment would allow the system to be 
used if its components are designed for a MAWP of 250 psig regardless 
of whether it was put into service before June 1, 1991, or if the MAWP 
is a result of upgrading components.
---------------------------------------------------------------------------

    \11\ Enforcement Discretion Memorandum for Mobile Refrigeration 
Units--https://www.regulations.gov/document?D=PHMSA-2016-0085-0004.
---------------------------------------------------------------------------

    As described in the RIA, although PHMSA describes the nature of 
cost savings associated with adoption of this petition, PHMSA was 
unable to estimate the cost savings with sufficient accuracy to 
quantify them due to data uncertainties. Therefore, in this final rule, 
PHMSA is revising Sec.  173.5b to allow the continued use of certain 
portable and mobile refrigerator systems that meet the 250 psig service 
pressure specification by removing the prohibition on use of 
refrigeration systems placed into service before June 1, 1991. Further, 
PHMSA, as of the effective date of this final rule, withdraws its 
September 28, 2017, enforcement discretion regarding the phase-out of 
mobile refrigeration systems because it will no longer be necessary.

7. Incorporation by Reference of CGA Standards

    PHMSA received multiple petitions to update CGA standards currently 
incorporated by reference in Sec.  171.7 of the HMR. These petitions 
include:
     Petition P-1679. CGA requests that PHMSA incorporate by 
reference CGA C-6.3, ``Standard for Visual Inspection of Low Pressure 
Aluminum Alloy Cylinders, 2013, Third Edition'' \12\ into Sec.  171.7 
to replace the outdated reference to the First Edition of this standard 
published in 1991. This publication is an industry standard governing 
periodic inspection of aluminum alloy compressed gas cylinders with 
service pressures of 500 psi (3450 kPa) or less. Notable changes from 
the previous edition consist of updating HMR citations and changing the 
characterization of the document from a ``guideline'' to a 
``standard.''
---------------------------------------------------------------------------

    \12\ The previous edition of this document was titled, 
``Guidelines for Visual Inspection and Requalification of Low 
Pressure Aluminum Compressed Gas Cylinders, 1991, First Edition.''
---------------------------------------------------------------------------

     Petition P-1680. CGA requests that PHMSA incorporate by 
reference CGA S-7, ``Method for Selecting Pressure Relief Devices for 
Compressed Gas Mixtures in Cylinders, 2013, Fifth Edition'' into Sec.  
171.7 to replace the outdated reference to the Fourth Edition of this 
standard published in 2005. This industry standard governs methods for 
selecting pressure relief devices (PRDs) for compressed gas mixtures 
packaged in cylinders having water capacities of 1000 lb (454 kg) or 
less. Notable changes from the previous edition of this document 
includes revising reference temperatures, changing the characterization 
of this document from a ``publication'' to a ``standard,'' and 
expanding its scope to address PRDs for five additional gases.
     Petitions P-1684 and P-1693. In two separate petitions, 
Worthington Cylinders and CGA request that PHMSA incorporate by 
reference CGA C-11, ``Practices for Inspection of Compressed Gas 
Cylinders at Time of Manufacture, 2013, Fifth Edition'' into Sec.  
171.7 to replace the outdated reference to the Third Edition of this 
standard published in 2001. These petitions also request revisions to 
Sec.  178.35(b) and (c) to refer to CGA C-11. This updated publication 
outlines best practices for inspection of cylinders consistent with 
industry practice and clarifies the parameters of inspector actions 
when inspecting compressed gas cylinders.
     Petition P-1694. CGA requests that PHMSA incorporate by 
reference CGA C-6.1-2013, ``Standards for Visual Inspection of High 
Pressure Aluminum Compressed Gas Cylinders'' into Sec.  171.7 to 
replace the outdated reference to the Fourth Edition of this standard 
published in 2002. This standard was developed for the visual 
inspection of aluminum alloy compressed gas cylinders with service 
pressures of 1800 psi (12410 kPa) or greater. Notable changes from the 
previous edition of this publication include new guidelines for the use 
of ultrasonic inspection (UE), and incorporation by reference of 
another CGA publication (CGA Safety Bulletin 22 Aluminum Cylinders--
Guidelines for Heat Exposure) for use with aluminum cylinders.
    PHMSA evaluated the recommended CGA standards as part of its 
technical review of these petitions. In each instance, PHMSA compared 
the two editions--the edition currently incorporated by reference in 
the HMR and the update edition proposed to be incorporated by the 
petitioner--for any changes or substantial revisions. PHMSA found only 
non-substantial revisions during that review and determined that they 
would not result in a reduction in safety. Moreover, insofar as the 
revisions in the updated CGA standards reflect lessons learned from 
operational experience and best practices developed since the earlier 
standards were placed in effect, incorporation of those updated 
standards could promote safety. There were no quantifiable cost savings 
identified, as these revisions to the CGA standards incorporated by 
reference are primarily technical in nature and are not expected to 
have a material effect on the cost of business. A more detailed 
discussion of the economic analysis can be found in the accompanying 
RIA.

[[Page 75686]]

    PHMSA received comments from CGA, COSTHA, and Gentry Investigative 
Service (GIS) in support of this proposal. However, in its comment, GIS 
notes that there are newer editions of the CGA publications and 
suggests that these editions should be incorporated as part of this 
final rule. Although PHMSA acknowledges that newer editions have been 
recently developed, PHMSA declines to incorporate by reference in this 
rulemaking newer editions of CGA documents. PHMSA has yet to evaluate 
those more recent editions, which were not proposed in the HM-219C 
NPRM. PHMSA, however, encourages industry to petition PHMSA to include 
any newer edition of incorporated-by-reference publications as desired 
and supported by technical analysis within those petitions.
    Therefore, in this final rule, PHMSA is updating CGA standards 
incorporated by reference in Sec.  171.7 of the HMR as proposed in the 
NPRM.

8. Special Provision for Explosives

    In its petition (P-1681), IME requests that PHMSA remove special 
provision 103 from Sec.  172.102 and from Column (7) of the HMT for the 
following entries: ``UN0361, Detonator assemblies, non-electric, for 
blasting''; ``UN0365, Detonators for ammunition''; ``UN0255, 
Detonators, electric, for blasting''; and ``UN0267, Detonators, non-
electric, for blasting.'' IME explains that this change would harmonize 
the HMR with the UN Model Regulations, and would enhance continuity 
when transporting these materials domestically and internationally. 
PHMSA proposed these changes in the NPRM and PHMSA received comments in 
support from IME, Owen Compliance Services, and COSTHA.
    Special provision 103 restricts classification of detonators as 
Division 1.4B if they are shipped in packages containing more than 25 
grams of net explosive mass that could be involved in a limited 
propagation explosion. However, the UN Model Regulations contain no 
quantified mass restriction for the same materials: rather, they 
require only that detonators must pass the tests prescribed by the UN 
Manual of Tests and Criteria (MTC)--in this case, the UN Test Series 6 
requirements--to be classified as Division 1.4B. The UN MTC contains 
the criteria, test methods, and procedures used for the classification 
of dangerous goods (i.e., hazardous materials) per the provisions of UN 
Model Regulations to ensure an appropriate level of safety, and 
demonstrate whether exposure of the material to fire or explosion 
during shipment conditions will result in a mass detonation of the 
material. Only those detonators that successfully pass tests prescribed 
for Division 1.4B may be classed in this hazardous materials category.
    PHMSA agrees that the removal of special provision 103 would 
harmonize with the international regulations and would have no negative 
impact on safety. Special provision 103 is outdated, as the HMR has 
since aligned its classification methodologies with the UN performance-
based classification method to improve harmonization with the 
internationally-accepted system for the classification of explosives. 
Finally, the operational experience of safe transportation of these 
materials pursuant to UN Model Regulations provides further evidence 
that the amendments to the HMR as proposed will not adversely affect 
safety--particularly as other HMR requirements would still apply to 
assure safe shipment. However, since special provision 103 is no longer 
widely used, PHMSA does not expect there would be any quantifiable cost 
savings. A more detailed discussion of the economic analysis can be 
found in the accompanying RIA.
    Therefore, in this final rule, PHMSA is removing the references to 
special provision 103 from four entries in Column (7) (Special 
provisions) of the HMT, and removing special provision 103 from Sec.  
172.102 altogether.

9. Safety Devices

    In its petition (P-1683), the Ford Motor Company requests that 
PHMSA remove the word ``None'' from Column (8A) of the HMT for the 
proper shipping name ``UN0503, Safety Devices, pyrotechnic'' and 
replace it with ``166,'' which would allow for the packaging exceptions 
currently authorized for other safety devices in Sec.  173.166.
    PHMSA proposed this revision in the HM-219C NPRM. PHMSA separately 
published a notice of request for information (RFI) in the Federal 
Register soliciting information and data from stakeholders regarding 
the classification, testing, and conditions for transportation relevant 
to the potential classification of safety devices.\13\ To ensure a more 
fulsome safety analysis of the HMR amendments requested in P-1683, 
PHMSA is not adopting the amendments proposed in the NPRM at this time 
and may instead consider them in a future rulemaking that could be 
informed by the information and data received in response to the RFI.
---------------------------------------------------------------------------

    \13\ 85 FR 35368 (June 9, 2020). PHMSA has continued to see 
advancements in technologies for articles containing hazardous 
materials; those advancements have been the subject of requests for 
approvals or special permits for transportation as safety devices 
(UN0503 and UN3268). As such, PHMSA is, in the RFI, requesting 
information or data from stakeholders regarding the classification, 
testing, and conditions for transportation of these devices 
requesting an approval to be classified as safety devices.
---------------------------------------------------------------------------

10. Alternative Reports for Cargo Tanks

    In its petition (P-1685), Polar Service Systems requests that PHMSA 
revise Sec.  180.417(a)(3) to remove the words ``manufactured before 
September 1, 1995,'' thereby allowing an alternative report in lieu of 
obtaining the manufacturers certificate of compliance for cargo tanks 
manufactured after September 1, 1995. The petitioner notes that there 
is no provision to allow for the use of alternative reports when a 
certificate of compliance is unavailable for cargo tanks manufactured 
after September 1, 1995,\14\ and explains that some cargo tank 
manufacturers have gone out of business in the past 25 years, making it 
impossible for a tank owner to obtain a missing certificate of 
compliance from these manufacturers. Therefore, these alternative 
reports would replace a missing certificate of compliance for cargo 
tanks manufactured after September 1, 1995. PHMSA received no comments 
on this proposed revision in the NPRM.
---------------------------------------------------------------------------

    \14\ See 59 FR 1786 (Jan. 12, 1994).
---------------------------------------------------------------------------

    PHMSA's technical review of the petition determined there are 
challenges in maintaining the required documentation for cargo tanks 
and cargo tank motor vehicles when cargo tank manufacturers are no 
longer in business. This is true irrespective of the timeframe set 
forth in Sec.  180.417. Further, PHMSA does not expect there would be a 
reduction in safety in allowing alternative reports for cargo tanks 
manufactured after September 1, 1995, because the testing and 
recordkeeping requirements that PHMSA would demand in those alternative 
reports provide much of the same information that would be in a 
manufacturer's certificate. Further, PHMSA's experience administering 
the alternative reporting requirement under existing HMR provisions 
demonstrates that extension of this compliance flexibility to 
additional cargo tanks would not adversely affect safety. Similarly, 
this amendment is not expected to result in any material cost to 
industry; rather, cargo tanks manufactured after September 1, 1995, 
with useful life remaining would not be forced out of service, thereby 
saving regulated entities the cost of replacement. A more detailed

[[Page 75687]]

discussion of the economic analysis can be found in the accompanying 
RIA.
    Therefore, in this final rule, PHMSA is revising the language in 
Sec.  180.417(a)(3) to allow for alternative reports when a 
manufacturer's certificate is not available regardless of the date of 
manufacture of the cargo tank.

11. Weight Tolerances for Paper Shipping Sacks

    In its petition (P-1688), the Paper Shipping Sack Manufacturers 
Association requests that PHMSA amend Sec.  178.521 to revise the basis 
weight tolerances for liners and mediums used in the manufacture of 
multi-wall shipping sacks from 5 percent to 10 
percent from the nominal basis weight reported to PHMSA in the initial 
design qualification test. The petitioner explains that multi-wall 
sacks are manufactured on the same or technically equivalent machines 
that manufacture the liners for fiberboard boxes and further notes that 
PHMSA revised the basis weight tolerances from 5 percent to 
10 percent for fiberboard boxes in the HM-219A final 
rule.\15\
---------------------------------------------------------------------------

    \15\ 83 FR 55792 (Nov. 7, 2018).
---------------------------------------------------------------------------

    PHMSA notes that the petitioner is correct in that the paper used 
to manufacture multi-wall shipping sacks is made on the same or similar 
machines as those used to make fiberboard boxes. Given the technical 
data presented in the petition, which included linerboard drop and 
dynamic compression tests, PHMSA concluded that a small reduction (or a 
nearly infinite increase) in basis weight of the paper used in 
manufacturing fiberboard boxes would not affect the safety of the 
packaging, and PHMSA expects that multi-wall shipping sacks--made of 
similar materials and manufactured on the same or technically 
equivalent machines--will behave similarly such that there will be no 
adverse impact to safety. Furthermore, PHMSA estimates the total 
potential annualized cost savings to the industry of between $20,000 
and $200,000. A more detailed discussion of the economic analysis can 
be found in the accompanying RIA.
    PHMSA received one comment from David Carlson in support of this 
proposal. However, in addition to his support, Mr. Carlson requested 
that PHMSA extend a similar provision to 11G packagings in this final 
rule. PHMSA notes that 11G packagings were not discussed in the NPRM, 
and while there may be merits to this proposed revision, PHMSA has not 
conducted a technical analysis of that proposal and is not adopting it 
at this time. PHMSA would like to allow further stakeholder engagement 
and opportunity to comment on any proposed changes before making this 
specific determination. The commenter is encouraged to petition PHMSA 
with supporting data to include 11G packagings in a future rulemaking.
    Therefore, based on its technical analysis showing no negative 
impact on safety, PHMSA is amending Sec.  178.521 to revise the nominal 
basis weight reported in the initial design qualification test report 
from 5 percent to 10 percent.

12. Markings on Closed Transport Containers

    In its petition (P-1690), Matson requests that PHMSA amend Sec.  
173.308(d)(3) to remove the requirement for a warning to be placed on 
the access door of a closed transport vehicle or a closed freight 
container when lighters are transported by vessel. Matson explains that 
the IMDG Code does not require a similar warning, thereby noting 
inconsistencies between the HMR and the international requirements that 
could cause confusion regarding the pertinent requirements governing 
international shipments. PHMSA received one comment from IVODGA in 
support of this proposal. The petitioner is correct in that the current 
HMR requirement is inconsistent with the IMDG Code. The IMDG Code does 
not require this additional marking and has not experienced an 
appreciable adverse safety impact. PHMSA is, further, unaware of a 
compelling safety justification for requiring the marking--particularly 
as other HMR hazard communication requirements (such as transport 
documents and container placards) would remain operative even if the 
amendment is adopted. In addition, the amendment would improve the 
internal consistency of the HMR, which does not impose the same 
restriction on other packages containing a Division 2.1 flammable gas 
as it does packages composed of lighters containing Division 2.1 
flammable gasses. Furthermore, while PHMSA was unable to quantify any 
specific cost savings associated with this amendment, no costs are 
anticipated. A more detailed discussion of the economic analysis can be 
found in the accompanying RIA.
    Therefore, based on its technical analysis, PHMSA is amending Sec.  
173.308(d)(3) to remove the requirement for vessel transport of a 
closed transport vehicle or freight container to display the warning 
mark ``WARNING--MAY CONTAIN EXPLOSIVE MIXTURES WITH AIR--KEEP IGNITION 
SOURCES AWAY WHEN OPENING'' on the access door.

13. Finalization of the HM-246 Tank Car Standard

    In a joint petition (P-1691), AAR, CI, ACC, TFI, and the Railway 
Supply Institute (RSI) request that PHMSA revise Sec. Sec.  173.314(c) 
and 173.244(a)(2) of the HMR to convert ``interim'' rail tank car 
specifications to ``final'' tank car specifications. The interim tank 
car specifications were issued as part of the HM-246 final rule titled, 
``Hazardous Materials: Improving the Safety of Railroad Tank Car 
Transportation of Hazardous Materials'' \16\ to be used for rail tank 
cars transporting PIH materials until PHMSA issued a permanent 
standard. The petitioners note that the PIH tank cars built in 
compliance with the HM-246 interim specifications have performed well 
and with no noteworthy safety concerns.
---------------------------------------------------------------------------

    \16\ 74 FR 1769 (Jan. 13, 2009).
---------------------------------------------------------------------------

    The HM-246 final rule prescribed enhanced safety measures for PIH 
materials transported in rail tank cars. These safety measures include 
stronger tanks made from normalized steel and capable of withstanding 
higher tank test pressures, fittings, tank head-puncture resistance 
protection, and thermal protection for some commodities. The HM-246 
final rule was the result of industry consensus that an updated 
regulatory standard was necessary to improve accident survivability, 
even as research continued to develop a long-term PIH tank car 
specification. Following publication of the HM-246 final rule and 
adoption of the interim specifications, the Advanced Tank Car 
Collaborative Research Program (ATCCRP) \17\ suggested the HM-246 
interim specifications provide significant safety improvements over 
legacy designs and noted a scarcity of other feasible options beyond 
the interim specifications. In addition, conclusions from various 
ATCCRP projects provide scientific support to make the interim 
specifications permanent. Conclusions resulting from these safety 
research efforts, as reported by ATCCRP, include:
---------------------------------------------------------------------------

    \17\ The ATCCRP coordinates research efforts to enhance the 
safety and security of rail tank car shipments of toxic-by-
inhalation hazard (TIH) materials. It is a joint effort comprised of 
shippers of tank cars carrying TIH materials (represented by ACC, 
CI, and TFI); railroads that transport hazardous materials 
(represented by AAR); and rail tank car builders and lessors 
(represented by RSI). For more information, see https://tankcarresourcecenter.com/wp-cojntent/uploads/2017/11/ATCCRP-Research-Background-2016.pdf.
---------------------------------------------------------------------------

     The interim specifications provide significant improvement 
in accident

[[Page 75688]]

survivability over the legacy designs (i.e., legacy specifications); 
and
     No design feature or material was identified that would 
provide a significantly greater level of improvement, or would be a 
reasonable alternative (from an economic or manufacturability 
standpoint) that should be required industry-wide.
    PHMSA received comments to the HM-219C NPRM from AAR, The Dow 
Chemical Company, Chemours, and a joint comment from ACC, CI, and TFI 
in support of this proposal. These commenters noted that by re-
designating the HM-246 specifications as permanent, PHMSA will provide 
regulatory certainty to the stakeholder community that an ``interim'' 
standard cannot. In its comment, AAR recommended that PHMSA coordinate 
with Transport Canada (TC) to assign a unique designator when 
translating the interim tank car specifications into permanent tank car 
specifications. PHMSA agrees with AAR and collaborated with TC during 
the final rule drafting stage to assign a unique designator to denote 
those permanent tank car specifications. This unique identifier will 
help ensure that tank cars used to transport PIH materials built to the 
permanent specifications can more easily move between the United States 
and Canada without encountering delays.
    PHMSA's technical review of this petition determined that the HM-
246 compliant rail tank cars have an established safety record with no 
major incidents attributed to the tank car design. As explained by 
ATCCRP and discussed at greater length in Section IV.14. (Phase-out of 
Non-HM-246 Compliant Rail Tank Cars), the HM-246 interim specifications 
represent a substantial safety improvement over legacy tank cars in PIH 
service. This amendment is not expected to result in any new material 
costs to industry. Any costs associated with phasing out legacy tank 
cars result from the decision by AAR to utilize interchange agreements 
to mandate retirement of these cars from PIH service by the date 
(December 31, 2027) specified in CPC-1336; this final rule would align 
the HMR with those industry efforts. A more detailed discussion of this 
economic analysis can be found in the accompanying RIA.
    Therefore, in this final rule, PHMSA is amending Sec. Sec.  
173.314(c) and 173.244(a)(2) of the HMR to make the HM-246 rail tank 
car specifications permanent for the transportation of PIH materials 
and is assigning the unique identifier of ``DOT-105H600W'' for HM-246 
tank cars transporting PIH materials by rail.

14. Phase-Out of Non-HM-246 Compliant Rail Tank Cars

    In its petition (P-1692), AAR requests that PHMSA amend Sec.  
173.31 to adopt a 6-year phase-out for PIH rail tank cars that do not 
meet the interim HM-246 specifications as implemented in the HM-246 
final rule published on January 13, 2009. Specifically, AAR argues that 
collaborative research undertaken by industry and government partners 
(through ATCCRP) has confirmed that HM-246 specification cars have the 
highest accident survivability rate over other designs and are the most 
feasible available technology to transport PIH materials.
    In 2006, after several major PIH rail tank car accidents, AAR began 
to release a series of CPCs that mandated the use of a safer design for 
tank cars that transport PIH materials. On March 31, 2008, AAR 
published CPC-1187, which implemented design specifications for tank 
cars used in PIH service and included a 10-year phase-out schedule for 
tank cars that did not meet the CPC-1187 specifications. According to 
CPC-1187, non-compliant tank cars would not be accepted for interchange 
after December 31, 2018. PHMSA published an NPRM \18\ proposing 
revisions to the HMR to improve the crashworthiness protection of rail 
tank cars designed to transport PIH materials on April 1, 2008 and 
later issued a final rule establishing the interim HM-246 
specifications in January 13, 2009. The interim HM-246 specifications 
effectively adopted AAR's CPC-1187 tank car specifications for the 
transportation of PIH materials until further research could be 
completed on enhanced tank car specifications.
---------------------------------------------------------------------------

    \18\ 73 FR 17817 (Apr. 1, 2008).
---------------------------------------------------------------------------

    In the HM-246 NPRM, PHMSA considered adopting a phase-out of tank 
cars that did not meet the proposed interim specifications. However, 
PHMSA did not codify a phase-out timeline in the final rule, stating 
``[a]lthough PHMSA continues to expect that an accelerated phase-out of 
these cars is justified, PHMSA recognizes the voluntary efforts already 
underway by many fleet owners to phase out these cars, in many cases on 
schedules more aggressive than the five-year deadline proposed in the 
NPRM.'' \19\ Instead, the HM-246 final rule adopted the interim tank 
car specifications; subsequently, AAR suspended CPC-1187 until new tank 
car specifications could be finalized and suspended the December 2018 
retirement deadline for non-compliant tank cars.
---------------------------------------------------------------------------

    \19\ 74 FR at 1777-78.
---------------------------------------------------------------------------

    As discussed in the previous sub-section (``Finalization of the HM-
246 Tank Car Standard''), research conducted under the ATCCRP has since 
demonstrated that the HM-246 interim tank car specifications provide 
significant improvements in survivability and there is no reason to 
expect a different design would provide a significantly greater level 
of improvement. However, despite initial indications in 2009 that 
voluntary efforts would result in an accelerated phase-out of those 
tank cars in PIH service that failed to comply with the HM-246 interim 
specifications, the industry had not adopted a voluntary phase-out 
schedule as of December 2016 that would eliminate such tank cars from 
PIH service.
    On December 16, 2016, AAR submitted its petition (P-1692) 
requesting that PHMSA adopt a 6-year phase-out for PIH rail tank cars 
that do not meet the interim specifications as implemented in the HM-
246 final rule published on January 13, 2009. AAR argued that 
collaborative research undertaken by industry and government partners 
(through ATCCRP) over the last 7 years had confirmed that HM-246 
specification cars have the highest accident survivability rate over 
other designs and are the most feasible technology to transport PIH 
materials.
    Before PHMSA completed its review of P-1692, AAR adopted CPC-1325 
in April 2017, which implemented a mandatory phase-out by July 1, 2023, 
of any tank car in PIH service that does not comply with the HM-246 
interim specifications. Prior to AAR's adoption of CPC-1325, TFI 
commented to the P-1692 docket \20\ that it opposed implementation of 
the July 1, 2023, phase-out schedule. TFI contended that DOT has sole 
authority over hazardous materials packaging and that because AAR's 
adoption of the phase-out schedule was done without performing an 
economic analysis, it was impossible to estimate the full extent of its 
potential costs or benefits.
---------------------------------------------------------------------------

    Similar comments were relayed to PHMSA by a group of shipper 
associations during a January 13, 2017 meeting.\21\ AAR met with PHMSA 
and the Federal Railroad Administration (FRA) on August 1, 2017, during 
which AAR suggested its phase-out schedule did not conflict with DOT 
regulations and that the phase-out schedule was intended to remove an 
older, less-safe

[[Page 75689]]

car design from PIH service.\22\ PHMSA later notified AAR on December 
7, 2017, that it was accepting P-1692 and would conduct a ``safety and 
policy review that will aid in determining whether the HMR should 
mandate a phase-out period and, if so, what period would ensure safety 
and protect the public interest.'' \23\

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

    On July 27, 2018, AAR revised CPC-1325 and re-issued it as CPC-
1336, extending the phase-out schedule for non-HM-246 compliant tank 
cars from 6 years (July 1, 2023) to 10 years (December 31, 2027). On 
August 15, 2018, the railroads (represented by AAR) and a group of 
leading PIH material shippers (represented by ACC, CI, and TFI) 
submitted a joint comment to P-1692 proposing a phase-out date of 
December 31, 2027, for all non-HM-246 specification rail tank cars. The 
December 31, 2027, phase-out date is in lieu of the 6-year timeline 
requested in AAR's original petition. The joint commenters met with 
PHMSA on September 6, 2018, and urged PHMSA to act quickly in 
completing a rulemaking that would adopt the petition's proposed 10-
year phase-out timeline.\24\ The joint commenters contend that 
codifying the phase-out in the HMR would improve safety and increase 
market certainty. PHMSA in the NPRM proposed revision of the HMR to 
adopt the joint commenters' December 31, 2027 deadline. PHMSA received 
no adverse comments in response to that NPRM proposal. PHMSA received 
comments in support of this proposal from AAR, the Dow Chemical 
Company, Chemours, and a joint comment by ACC, CI, and TFI.
---------------------------------------------------------------------------

    \24\ Meeting Summary, available at https://www.regulations.gov/document?D=PHMSA-2016-0165-0014.
---------------------------------------------------------------------------

    PHMSA expects the phase-out of legacy rail tank cars for PIH 
service will have a positive impact on safety because they would be 
replaced with more robust tank cars for use in the transportation of 
PIH materials and because regulatory certainty could foster market 
certainty. In the NPRM, PHMSA proposed a phase-out deadline of December 
31, 2027; however, the phase-out will go into effect under mandatory 
railroad interchange rules regardless of whether PHMSA adopts this date 
into regulation. As a result, there is no cost associated with PHMSA 
promulgating this date as a regulatory deadline for the phase-out. A 
more detailed discussion of the economic analysis can be found in the 
accompanying RIA.
    As such, PHMSA is codifying the phase-out of all non-HM-246 rail 
tank cars for use in the transportation of PIH materials. PHMSA's 
actions in this final rule provide both shippers and carriers with 
regulatory certainty on the transportation of PIH materials by rail. 
This regulatory certainty makes transportation cost predictable to 
industry and--more importantly--locks-in safety benefits associated 
with industry's movement to phase-out non-HM-246 tank cars in the 
transportation of PIH materials by rail.
    Therefore, PHMSA is revising Sec.  173.31 to phase-out all non-HM-
246 rail tank cars for the transportation of PIH materials by December 
31, 2027, to align with the agreed upon phase-out dates between AAR and 
leading PIH material shippers.

15. Allow Non-RCRA Waste To Use Lab Pack Exception

    In its petition (P-1695), Veolia requests that PHMSA amend Sec.  
171.8 by adding a definition of ``waste material'' to allow for all 
waste material to be managed in accordance with the lab packs exception 
and associated paragraphs in Sec.  173.12, regardless of whether it 
meets the definition of a ``hazardous waste'' in EPA regulations 
implementing RCRA at 40 CFR 261.3. The ``lab pack exception'' for waste 
under Sec.  173.12(b) provides for exceptions from some HMR packaging 
requirements (such as those pertaining to chemical constituent marking 
and specification packaging requirements for combination packages) to 
facilitate transportation for disposal of certain waste materials when 
shipped in packages satisfying packaging requirements identified in 
that section. The petitioner notes that PHMSA has stated in a letter of 
interpretation (16-0099) \25\ that this exception only applies to 
``hazardous wastes'' as defined by EPA's regulations implementing RCRA; 
amendment of the HMR to make the lab pack exception in Sec.  173.12 
more broadly available to ``waste materials'' would provide regulatory 
relief in the disposal and recovery of hazardous materials. PHMSA 
received comments from Veolia and COSTHA in support of this proposal.
---------------------------------------------------------------------------

    \25\ PHMSA Letter of Interpretation, Reference No. 16-0099, 
available at https://www.phmsa.dot.gov/regulations/title49/interp/16-0099.
---------------------------------------------------------------------------

    PHMSA's technical review of the petition supports the petitioner's 
interpretation. Neither the regulatory text nor the preamble of the 
December 21, 1990 final rule codifying Sec.  173.12(b) indicate the lab 
pack exception is limited to ``hazardous wastes'' as that term is 
defined under the EPA's RCRA regulations.\26\ PHMSA expects that making 
all waste material eligible for the lab pack exception would not lead 
to a reduction in safety because waste materials present no greater 
hazard than materials defined as a hazardous waste according to the 
EPA's RCRA regulations. Further, insofar as the lab pack exception 
would make it easier for regulated entities without sophisticated 
compliance programs, or limited storage space, to dispose of waste 
consistent with the HMR, the final rule could improve safety. In 
addition, there are no costs expected based on this revision. Extension 
of the lab pack exception offers additional flexibility for 
transporting waste materials; it does not increase compliance costs or 
changes to how waste material is handled. A more detailed discussion of 
the economic analysis can be found in the accompanying RIA.
---------------------------------------------------------------------------

    \26\ See 55 FR 52402, 52423 (Dec. 21, 1990).
---------------------------------------------------------------------------

    Therefore, in this final rule, PHMSA is adding a definition of 
``waste material'' to allow for all waste material to be managed in 
accordance with the lab packs exception and associated paragraphs in 
Sec.  173.12.

16. Incorporation of ASME Code Sections II, V, VIII, and IX

    In its petition (P-1700), Trinity Containers requests that PHMSA 
incorporate by reference the 2017 edition of the ASME BPVC Sections II 
(Parts A and B), V, VIII (Division 1), and IX into Sec.  171.7(g)(1) of 
the HMR. The ASME BPVC is a consensus industry standard for the design 
and construction of boilers and pressure vessels. Significant revisions 
to the relevant portions of the ASME BPVC introduced in the 2017 
edition include the following:
     ASME BPVC Section II, Part A: Incorporation of 25 new 
American Society for Testing and Materials (ASTM) and 7 new 
international specifications authorized in connection within ferrous 
material within ASME-compliant boilers and pressure vessels;
     ASME BPVC Section II, Part B: Incorporation of 10 new ASTM 
specifications authorized for use in connection with non-ferrous 
material within ASME-compliant boilers and pressure vessels;
     ASME BPVC Section V: Incorporation of 19 new ASTM 
specifications providing for ASME-compliant methodologies in conducting 
non-destructive examination of boilers

[[Page 75690]]

and pressure vessels, as well as revisions of existing standards 
pertaining to acoustic emissions testing and block calibration;
     ASME BPVC Section VIII, Division 1: Revision of existing 
specifications for the construction of pressure vessels to expand 
coverage of openings and quick-action/actuation closures, clarify 
guidelines on performance of manual and automated ultrasonic testing, 
and provide new procedural pathways for manufacturers to obtain ASME 
certifications; and
     ASME BPVC Section IX: Revision of existing specifications 
for welding, brazing and fusing qualifications to expand acceptable 
testing methods and clarify welder personnel qualification 
requirements.
    The petitioner contends that without regulatory amendment, ASME 
certificate holders would be obliged to comply with obsolete industry 
standards for manufacturing cargo tanks, non-specification tanks, and 
implements of husbandry to the ASME BPVC referenced in Sec.  
171.7(g)(1).
    PHMSA received comments on this proposal from Global Transport Tank 
Consultants (GTTC), GIS, and NJP Engineering. GTTC requests that PHMSA 
clarify which sections are being updated and whether the updated ASME 
BPVC Section VIII, Division 1 ``Design Margin'' would be applicable to 
any of the cargo tank packaging ``designed'' to the requirements of 
ASME BVCP Section VIII, Division 1. In addition, GTTC asks if it was 
PHMSA's intention to require the repair of ASME ``marked'' packaging to 
meet the requirements of the 1992 edition of the National Board 
Inspection Code (NBIC) currently incorporated by reference in to HMR. 
GTTC and GIS request that PHMSA incorporate the 2019 editions of the 
ASME BPVC and the NBIC since they are currently available.
    NJP Engineering supports the HMR amendments proposed in the NPRM 
but requests correction of an alleged oversight by PHMSA in 
incorporating the 2015 edition of the ASME BPVC.\27\ NJP Engineering 
notes that the ASME BPVC standard contains a requirement for a 6 
percent knuckle radius on torispherical heads that is the subject of 
exception in three places (see Sec. Sec.  178.346-1(d)(8), 178.347-
1(d)(8), and 178.348(e)(2)(viii)) within the HMR. These HMR exceptions 
reference standard ASME BPVC standard UG-32(e) and were added to the 
HMR in response to the incorporation of the previous 1998 edition of 
the ASME BPVC. However, prior to the incorporation of the 2015 edition, 
ASME removed paragraph (b) from UG-32, resulting in the re-designation 
of the former UG-32(e) as UG-32(d). NJP Engineering seeks clarification 
that it was PHMSA's intention to retain those exceptions and recommends 
that ``UG-32(e)'' be replaced with ``UG-32(d)'' accordingly.
---------------------------------------------------------------------------

    \27\ See 81 FR 25613 (Apr. 29, 2016).
---------------------------------------------------------------------------

    In this final rule, PHMSA is incorporating by reference the 2017 
editions of the ASME BPVC Section II, Part A (Ferrous Materials 
Specifications); Section II, Part B (Nonferrous Material 
Specifications); Section V (Nondestructive Examination); Section VIII, 
Division 1 (Rules for Construction of Pressure Vessels Division); and 
Section IX (Welding, Brazing, and Fusing Qualifications). PHMSA's 
technical review of P-1700 determined that the HMR's incorporation by 
reference of the obsolete 2015 edition of the ASME BPVC could induce 
confusion among stakeholders about the controlling edition of the ASME 
BPVC. PHMSA agrees with the petitioner that adopting the updated 
edition would help ensure that the HMR remains consistent with the best 
practices used by the industry.
    The design margin(s) in the HMR for DOT specification cargo tanks 
remain as currently authorized; \28\ this rulemaking does not authorize 
the ``design margin'' described in the 2017 edition of the ASME BPVC 
Sections II (Parts A and B), V, VIII (Division 1), and IX into the HMR 
for DOT specification cargo tanks, even as it would apply to 
specification portable tanks. This distinction was clarified in a 
letter of interpretation (17-0083 \29\) published in response to 
PHMSA's incorporation by reference of the 2015 edition of the ASME BPVC 
Section VIII Division. This rulemaking did not consider incorporating 
the updated NBIC; however, the 2017 edition is under review currently 
as part of the HM-241 \30\ rulemaking. The 1992 edition of the NBIC 
currently incorporated by reference into the HMR will remain in effect 
for the repair of ASME packagings manufactured in accordance with the 
HMR. PHMSA will retain the exceptions in Sec. Sec.  178.346-1(d)(8), 
178.347-1(d)(8), and 178.348(e)(2)(viii), and agrees that ``UG-32(e)'' 
should be replaced with ``UG-32(d)'' provisions. PHMSA is making an 
additional editorial change to the HMR to update the references to UG-
32 as recommended by NJP Engineering. PHMSA expects that the cost-
savings associated with P-1700 would be modest. A more detailed 
discussion of this economic analysis can be found in the accompanying 
RIA.
---------------------------------------------------------------------------

    \28\ The ASME design margin does not apply to DOT specification 
cargo tanks because of the structural integrity sections in part 
178, which specify alternative design margins. In contrast, the ASME 
design margin applies to portable tanks as the HMR contains no 
exception allowing the use of an alternative design margin.

17. Import of Foreign Pi-Marked Cylinders

    In its petition (P-1701), CGA requests that PHMSA modify Sec. Sec.  
171.23, 173.302, and 173.304 to permit the transportation of filled pi-
marked foreign pressure receptacles in compliance with applicable 
requirements of the European Agreement Concerning the International 
Carriage of Dangerous Goods by Road (ADR) and EU Directive 2010/35/EU 
of the European Parliament and of the Council. The HMR currently allows 
pi-marked cylinders (which are filled and shipped within the EU and 
marked with a pi ([pi]) symbol to denote compliance with the ADR and EU 
Directive 2010/35/EU) to be imported through use of special permits. 
The petitioner requests revisions to the HMR authorizing without the 
need for a special permit, the (1) import, intermediate storage, 
transport to point of use, discharge, and export, as well as (2) import 
of empty pi-marked foreign pressure receptacles for filling, 
intermediate storage, and export. Entegris provided comments to the P-
1701 docket \31\ and requested additional revisions to Sec. Sec.  
171.23(a) and 173.302(a)(2) to allow shipment of adsorbed gasses within 
those pi-marked cylinders that were the subject of CGA's petition for 
rulemaking. The changes to Sec.  171.23(a)(3) requested by Entegris are 
intended to allow for domestic sourcing as well as the import of empty 
pi-marked pressure receptacles for filling and export.
---------------------------------------------------------------------------

    \31\ https://www.regulations.gov/docket?D=PHMSA-2017-0026.
---------------------------------------------------------------------------

    PHMSA's technical review did not find evidence to suggest there 
would be any adverse safety impacts resulting from those HMR 
amendments. The shipping of pi-marked cylinders within the United 
States has been allowed for many years through special permits--with at 
least 3,000 shipments occurring since the special permits were first 
issued; there is also extensive operational experience in the safe 
international shipment of pi-marked cylinders. Although there is 
limited market data on the current export of pi-marked cylinders 
pursuant to special permit, PHMSA expects that adopting

[[Page 75691]]

these amendments would not result in a change to the number of pi-
marked cylinders that are transported or the risk profile of their 
transportation. Nonetheless, cost savings are expected to be minimal, 
resulting primarily from the potential time savings for industry and 
government due to the elimination of the need for a special permit. A 
more detailed discussion of the economic analysis can be found in the 
accompanying RIA.
    PHMSA received comments from CGA and Chemours in support of this 
proposal. COSTHA notes that the 2017 edition of the ADR is being 
referenced in Sec.  171.7 of the NPRM. COSTHA also notes that as of 
September 2019, the most current edition of the ADR is the 2019 edition 
that became effective July 1, 2019. PHMSA will consider updating this 
reference in a future rulemaking, as it has yet to conduct a technical 
evaluation of the 2019 edition of the ADR.
    In this final rule, PHMSA is modifying Sec. Sec.  171.23, 173.302, 
and 173.304 to permit the import of filled pi-marked foreign pressure 
receptacles for storage incidental to movement, transport to point of 
use, discharge, and export. PHMSA is also permitting the transportation 
of pi-marked foreign pressure receptacles for export, including filling 
and storage incidental to movement. In addition, PHMSA is revising 
Sec. Sec.  171.23(a) and 173.302(a)(2) to ensure that the authorization 
for pi-marked cylinders is applicable to adsorbed gas packages. 
Finally, to align with similar ADR provisions and increase shipper and 
carrier awareness of the requirements for pi-marked cylinders, PHMSA is 
requiring a notation on the shipping paper following the basic 
description of the hazardous material to certify compliance with the 
pi-marked cylinder requirements. PHMSA is updating Sec.  171.7 to 
include the ADR and EU Directive 2010/35/EU of the European Parliament 
and of the Council into the HMR.

18. Placement of the Word ``Stabilized'' in Shipping Description

    In its petition (P-1706), Evonik requests that PHMSA revise how the 
word ``stabilized'' should appear when providing the shipping name for 
a hazardous material to maintain consistency with the IMDG Code. The 
HMR does not allow the word ``stabilized'' to appear as part of the 
proper shipping name, whereas the IMDG Code requires it, when 
stabilization is required prior to transportation. The petitioner 
claims that this causes needless discrepancies with the IMDG Code in 
connection with international shipments. PHMSA received comments from 
the Dow Chemical Company, Dangerous Goods Advisory Council (DGAC), and 
IVODGA supporting this proposal.
    PHMSA's technical review confirmed inconsistency between the HMR 
and the IMDG Code and revealed that hazardous materials that have some 
instability but that are not specifically identified or classified as 
self-reactive substances or organic peroxides cannot be shipped in 
compliance with both the IMDG Code and the HMR as currently written. In 
addition, PHMSA determined that requiring the use of the word 
``stabilized'' when stabilization is required by Sec.  173.21(f) would 
not result in any reduction in safety, but would instead increase 
safety by indicating that a material has been stabilized in preparing 
it for transportation. Although this amendment may incur costs for 
manufacturers and shippers related to training and compliance, costs 
are expected to be negligible because affected entities that engage in 
international commerce are already aware of the requirement under the 
IMDG Code. A more detailed discussion of the economic analysis can be 
found in the accompanying RIA.
    Therefore, in this final rule, PHMSA is revising Sec.  172.101(c) 
to clarify that the word ``stabilized'' must be included as part of the 
proper shipping name when the HMR requires stabilization before 
transportation.

19. Incorporation by Reference of an AESC/IME Standard

    In its petition (P-1710), IME requests that PHMSA update Sec.  
171.7(r) to update IME's corporate address and incorporate by reference 
the AESC/IME JPG Standard, also called the ``Guide to Obtaining DOT 
Approval of Jet Perforating Guns using AESC/IME Perforating Gun 
Specifications,'' Version 02, dated September 1, 2017. IME also 
proposes that PHMSA include a new Sec.  173.67 codifying PHMSA's 
current practice excepting JPGs conforming to the AESC/IME JPG Standard 
from the exhaustive testing generally required pursuant to Sec.  173.56 
to receive an EX number authorizing transportation of a new 
explosive.\32\
---------------------------------------------------------------------------

    \32\ PHMSA's use of the 2008 version of the AESC/IME JPG 
Standard in its Sec.  173.56 reviews is an informal practice and not 
a regulatory requirement. See Correspondence from Theodore L. Willke 
(PHMSA) to Lon Santis (IME) (Nov. 19, 2008), http://www.ocsresponds.com/ref/AESC-IMEPerfGunApproval(2008.11.19).pdf.
---------------------------------------------------------------------------

    JPGs use shaped explosive charges to produce a high-pressure jet 
penetrating the liner or casing of a wellbore to enhance production of 
oil and gas wells. The petitioners note that the initial version of the 
AESC/IME JPG Standard has been used by PHMSA since 2008. Entities 
seeking PHMSA's assignment of an EX number for a JPG product submit 
applications demonstrating conformity with one of 13 standard design 
templates within the AESC/IME JPG Standard, thereby avoiding having to 
submit their product for explosive laboratory testing normally required 
under Sec.  173.56. IME submits that the HMR amendments identified in 
its petition would codify existing PHMSA practices for review of JPG 
products under Sec.  173.56. PHMSA received no adverse comments on the 
petition or the proposals in the NPRM.
    PHMSA expects that adoption of the petition as proposed in the NPRM 
will not have an adverse effect on safety. PHMSA has relied on AESC/
IME's JPG Standard to expedite its review of applications since 2008; 
PHMSA is unaware any significant operational or testing experience 
indicating that historical practice is unsafe. Further, the most recent 
version of the AESC/IME JPG Standard is potentially more conservative 
than the current standard, as it would narrow the universe of JPG 
product designs (from 13 to 8) eligible for expedited review to only 
those 1.1D products without a detonator. Furthermore, the economic 
analysis suggests potential annualized cost savings of approximately 
$360,000 for manufacturers of JPGs that would avail themselves of the 
newly-codified regulations incorporating the updated AESC/IME JPG 
Standard to avoid the need for explosives laboratory testing. 
Additional cost savings are expected for both manufacturers and PHMSA 
due to reduced labor requirements for processing applications for EX 
approvals. A more detailed discussion of the economic analysis can be 
found in the accompanying RIA.
    Therefore, in this final rule, PHMSA is updating IME's address in 
Sec.  171.7(r), incorporating the updated AESC/IME JPG Standard into a 
new Sec.  171.7(r)(3) of the HMR, and adding a new Sec.  173.67 
codifying existing practice allowing AESC/IME JPG Standard-compliant 
products access to expedited PHMSA review under Sec.  173.56.

20. Incorporation by Reference of an Updated APA Standard 87-1

    In its petition (P-1711), the APA requests that PHMSA incorporate 
by reference the 2018 edition of APA Standard 87-1, ``Standard for 
Construction and Approval for Transportation of Fireworks, Novelties,

[[Page 75692]]

and Theatrical Pyrotechnics'' \33\ to replace the outdated reference to 
the 2001 edition of this standard, noting advances in product safety 
and design in the fireworks industry over the last 15 years. 
Significant changes from the previous edition of APA Standard 87-1 
include the following:
---------------------------------------------------------------------------

    \33\ APA Standard 87-1 is a consensus industry standard in which 
fireworks classifications are assigned based upon the weight and 
type of chemical composition for each type of device, including 
specific permissible and restricted chemicals.
---------------------------------------------------------------------------

     Re-organizing Standard 87-1 into three parts: APA Standard 
87-1A (consumer fireworks), APA Standard 87-1B (display fireworks), and 
APA Standard 87-1C (entertainment and technical industry fireworks, 
otherwise referred to as articles pyrotechnics).
     Updating the product descriptions throughout each of those 
parts to accommodate new types and configurations popularized since the 
2001 edition of APA Standard 87-1.
    The petitioner contends that because the classification system in 
the 2001 edition of APA Standard 87-1 does not reflect new product 
types and configurations (e.g., combination devices containing multiple 
tubes, and combinations of effects previously limited to single tubes), 
those new products are not eligible pursuant to Sec. Sec.  173.64 and 
173.65 for expedited PHMSA review and approval.\34\ The petitioner 
submits that incorporation by reference of the updated version of APA 
Standard 87-1 would relieve administrative burdens on industry by 
facilitating expedited PHMSA review and approval of fireworks products 
and provide regulatory certainty regarding compliance with the HMR.
---------------------------------------------------------------------------

    \34\ Sections 173.64 and 173.65 permit fireworks manufactured in 
compliance with APA Standard 87-1 to be classified and approved on 
an expedited basis, as each application for a new fireworks product 
would otherwise have to provide product-specific testing required 
under Sec.  173.56 to obtain an EX number from PHMSA authorizing 
their transportation.
---------------------------------------------------------------------------

    PHMSA received numerous comments to the NPRM regarding this 
petition, and to address each issue, PHMSA broke them out into the 
following sub-sections for detailed discussion.
General Comments: Support
    PHMSA received comments in support of this proposal from Charles 
Ward; Huang Johnson; Western Enterprises Inc.; ResPyro (Steve Comen); 
StageFX (Lyle Salmi); Galaxy Fireworks, Inc.; ResPyro (Kent Orwoll); 
NextFX; Fireworks Over America; Dennis Slicer; Santore and Sons; 
Pyrotechnics Guild International (Paul Smith); Garrett's Fireworks; 
ICON Pyrotechnics Internationals; American Fireworks Standards 
Laboratory (AFSL); Inter-Oriental Fireworks LTD; APA; APA Rebuttal to 
National Fireworks Association (NFA); and Matthew Jones. These 
commenters generally supported incorporating the updated APA Standard 
87-1, noting that it will add numerous new devices, expand the 
permitted chemical list, and is directed toward hazard classification 
for transportation. The commenters add that the updated APA Standard 
87-1 provides defined criteria that will relieve the burden of 
submitting new fireworks designs to a third-party test lab for 
classification and will reduce the regulatory burden on industry, 
including manufacturers and small business importers, who often have to 
spend their time helping their foreign manufacturers obtain EX 
approvals.
General Comment: Opposed
    PHMSA received comments opposing incorporation of APA Standard 87-
1A from Yienger Fireworks, NFA, and Crazy Debbie's Fireworks. NFA and 
Crazy Debbie's Fireworks explain that while many of the proposed 
revisions to APA Standards 87-1A, B, and C would clarify the 
requirements applicable to fireworks devices, there are certain 
revisions in APA Standard 87-1A that will not reduce regulatory burdens 
and do not relate to improving transportation safety. These commenters 
further contend that APA Standard 87-1A would conflict with the 
regulatory regime of the Consumer Product Safety Commission (CPSC) 
governing the safety of fireworks from a consumer-use standpoint.
    Instead, PHMSA's incorporation of APA Standard 87-1 pertains to its 
distinguishable jurisdictional responsibility over regulation of 
packaging and transportation of fireworks and other hazardous 
materials. PHMSA-imposed restrictions on packaging and shipment of 
hazardous materials for transportation that give rise to incidental 
effects on the way those materials are marketed to consumers are, 
therefore, not duplicative or conflicting regulations. In addition, 
PHMSA notes that the APA 87-1 standards were developed with the 
resources of the APA, which welcomed broad input and participation from 
the fireworks industry. APA allowed organizations, including the NFA, 
to participate in that process as an organization.
Comments Regarding Section 2.4: Break/Burst Charge Limits
    PHMSA received several comments on section 2.4 of APA Standard 87-
1A, which outlines the general requirements that must be met for 
construction and design of consumer firework devices and novelties. 
Jake's Fireworks, NFA, Crazy Debbie's Fireworks, Ultratec Special 
Effects and the APA provided comments specifically on the break/burst 
charge limits outlined in this section of APA Standard 87-1A:
     Jake's Fireworks contends that APA Standard 87-1A's 
limitation on metals in the composition of a break/burst charges was 
rejected by the CPSC commissioners, alleging that in doing so, the CPSC 
rejected metal composition as a factor in the safety of break/burst 
charges.
     Ultratec Special Effects states that some of the weight 
limit increases for devices per tube in APA Standard 87-1A will allow 
for a break/burst charge of 42.5 grams, which is more than enough to 
produce a salute device. It also claims that if these devices were 
subject to UN Series 6 testing, they would likely be classified as 1.3G 
or 1.1G devices, further adding that reports and airburst reports 
should always be subject to UN Series 6 testing since these devices are 
highly energetic and should be scrutinized for proper construction and 
packing techniques to ensure safe transportation. Ultratec Special 
Effects adds that many of these devices are currently unregulated due 
to older issued EX numbers that have vague specifications and no 
specified part numbers.
     NFA asserts that adoption of the language for break/burst 
charges in APA Standard 87-1A will not reduce regulatory burdens and 
will create conflict and confusion between agency regulations instead, 
further claiming that it is unrelated to safe transportation of 
hazardous materials in commerce.
     Crazy Debbie's Fireworks alleges that APA Standards 87-1A 
and C should have identical break/burst charge limits for the same 
fireworks. By way of example, Crazy Debbie's Fireworks notes that for 
the same firework--``UN0336, Fireworks, 1.4G''--each of APA Standard 
87-1A and Standard 87-1C impose two different break/burst composition 
restrictions. Under APA Standard 87-1A, this material is limited to 
less than 149 microns (100 mesh) metals in the break/burst charges, but 
APA Standard 87-1C states that aluminum particles greater than 53 
microns in diameter must not exceed 10 percent by weight of the break/
burst charge.

[[Page 75693]]

    APA Standard 87-1A's restrictions on metal size and chemical 
composition within break/burst charges for consumer fireworks are not 
new regulatory requirements; rather, they have been in place since the 
2001 edition of APA Standard 87-1 currently incorporated into Sec.  
171.7, as metal size and chemical composition directly impact hazard 
classification. For this reason, PHMSA is not persuaded by the 
commenters' arguments that APA Standard 87-1A's limitations on break/
burst device metal composition are unnecessary; rather, PHMSA 
understands those metal size limitations to be essential to safe 
transportation of consumer fireworks whose chemical structure and metal 
composition makes them inherently more dangerous than fireworks with 
different constituents. Further, even if the CPSC may not have had 
reservations about whether an adequate technical basis to conclude that 
the precise metal composition limits at issue in its rulemaking would 
ensure consumer product safety, PHMSA is satisfied, based on its 
experience regulating transportation of hazardous materials (an 
activity that involves a different risk profile than use of fireworks 
by individual consumers) that the approach taken in APA Standard 87-1 
and 87-1A is appropriate for its transportation regulatory oversight 
activities. PHMSA notes that none of the commenters on the NPRM 
provided technical or operational data supporting a contrary 
conclusion.
    In addition, Ultratec Special Effects' assertion that APA Standard 
87-1A will allow for an increased break/burst charge of 42.5 grams, and 
therefore allow salute device access to the expedited review processes 
under Sec. Sec.  173.64 and 173.65, is incorrect. A device containing a 
burst charge weight of 42.5 grams would not comply with either the 
existing APA Standard 87-1 nor the updated APA Standard 87-1A. The only 
weight increases in the updated APA Standard 87-1A pertain to fountain 
devices, which do not contain burst/break charges; the break/burst 
charge weight limit of 15 grams for aerial shells did not change. 
Devices with break/burst charges exceeding 15 grams would have to be 
submitted to a DOT-approved test laboratory pursuant to Sec.  173.56, 
where the device would be subjected to the UN Series 6 testing and 
subsequently reviewed by PHMSA.
    Further, although PHMSA acknowledges that the HMR allows the use of 
the default UN classification testing (including UN Series 6 testing) 
instead of reliance on compliance with APA Standard 87-1A, PHMSA is not 
convinced that UN Series 6 testing is necessarily superior to APA 
Standard 87-1A's approach of limiting the metal particle sizes and 
chemical composition. Indeed, insofar as both APA Standards (87-1 and 
87-1A) as well as the UN Model Regulations classify fireworks with an 
eye toward limiting the amount of flash powder compositions that can be 
present in fireworks, they do so by different approaches: APA Standard 
87-1 and the updated 87-1A do so by way of adjusting chemical 
composition and metal particle sizes to control flash powder 
compositions, while the UN Model Regulations rely on the use of a flash 
powder test to determine the presence of flash powder compositions. 
Based on its long experience regulating safe transportation of 
fireworks, PHMSA is satisfied that both the APA Standard (87 and 87-1A) 
and UN approaches are appropriate. PHMSA notes that none of the 
commenters on the NPRM provided technical or operational data 
supporting a contrary conclusion.
    PHMSA is aware of the different limits on metal size permitted 
under APA Standards 87-1A and C for the same UN0336, 1.4G firework. As 
explained above, PHMSA understands metal size to be an important factor 
in classifying fireworks to ensure their safe transportation. But metal 
size is not necessarily the only component that should be considered in 
the classification of fireworks under the HMR. Indeed, the differences 
between APA Standards 87-1A and C with respect to the same fireworks 
reflect the common-sense proposition that other characteristics of 
fireworks can influence their classification for regulation of their 
transportation--and that those transportation-relevant characteristics 
often derive from (or incidentally effect) the end uses of the 
fireworks. As explained by APA in supplemental comments submitted in 
response to Crazy Debbie's Fireworks et al., the chemical composition 
and design of articles pyrotechnics governed by APA Standard 87-1C are 
much more energetic than the consumer fireworks governed by APA 
Standard 87-1A--hence, the difference in authorized metal sizes despite 
the same 1.4G classification. PHMSA understands the different metal 
size limits for consumer applications (APA Standard 87-1A) and articles 
pyrotechnics applications (APA Standard 87-1C) to be appropriate.
Comments Regarding Reloadable Aerial Shell Kits
    PHMSA received comments from Jake's Fireworks, NFA, and Crazy 
Debbie's Fireworks, on sections 2.4 and 3.2.5.1 of APA Standard 87-1A 
pertaining to reloadable aerial shell kits. These commenters do not 
view those requirements (for fully assembled tubes, inner packaging and 
a base) as being related to the risk of harm in the transportation of 
these products, instead claiming they relate to the kits' packaging and 
design as it interfaces with the consumer, which they allege is subject 
to the jurisdiction of the CPSC and distinct from transportation safety 
regulated by PHMSA. NFA further claims adoption of this portion of the 
proposed language under section 3.2.5.1 will not reduce regulatory 
burdens, may create conflict and confusion between CPSC and PHMSA 
regulations, and eliminate a currently-allowed industry practice prior 
to an item being offered for retail sale.
    However, APA submitted supplemental comments noting that NFA, et 
al. were not criticizing the NPRM so much as existing HMR requirements 
as elaborated by PHMSA safety guidance \35\ on reloadable aerial shell 
kits. APA further explained that the transportation of completed kits 
with inner packaging significantly increases safety in the event of an 
incident occurring during transportation: If a trailer load or shipping 
container of reloadable shells did not have the separation provided by 
inner packaging required under APA Standard 87-1A, the product could 
behave as a 1.3G explosive and pose far more serious transportation 
risks than a 1.4G incident.

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

    PHMSA agrees with APA that Standard 87-1A's requirement for 
reloadable aerial shell kits to contain fully assembled tube and be 
packaged in an inner packaging with base is not a new regulatory 
requirement: Those elements are in the 2001 edition of APA Standard 87-
1, in addition to the PHMSA guidance identified above. PHMSA further 
agrees with APA that the requirements for inner packagings and bases 
for reloadable aerial shell kits in APA Standard 87-1A are important 
contributors to the safe shipment of aerial shell kits. Indeed, PHMSA's 
technical review regarding P-1710 included research yielding a 
preliminary conclusion that reloadable aerial shell kits can be shipped 
in bulk safely as 1.4G explosives.
Comments Regarding Appendices
    PHMSA received comments from Jake's Fireworks and the NFA on 
``Appendix VI: General Requirements

[[Page 75694]]

Pertaining to the Consumer Product Safety Commission.'' The commenters 
note that the requirements in Appendix VI do not relate to matters of 
transportation safety, but rather concern consumer safety issues which 
are within the jurisdiction of the CPSC.
    PHMSA agrees with the commenters that Appendix VI of APA Standard 
87-1A is within the jurisdiction of CPSC, and will therefore not 
incorporate it by reference in this final rule. Nor will PHMSA 
incorporate by reference any of Appendices II-V of APA Standard 87-1A, 
Appendices II-IV of APA Standard 87-1B, and Appendices II-IV of APA 
Standard 87-1C, as PHMSA has not conducted a technical evaluation of 
those Appendices.
Conclusion Regarding Incorporation by Reference of Updated APA Standard
    Based on PHMSA's technical analysis and the comments received on 
the NPRM, PHMSA will in this final rule incorporate by reference the 
updated APA Standards 87-1A, B, and C, with their respective Appendix I 
Permitted and Restricted Chemicals lists. Other Appendices of APA 
Standard 87-1A (Appendices II-VI), APA Standard 87-1B (Appendices II-
IV), and APA Standard 87-1C (Appendices II-IV) will not be incorporated 
by reference. PHMSA expects the updated APA Standards 87-1A, B, and C 
will provide clarity to the fireworks industry, while maintaining the 
composition restrictions for classification that are needed to ensure 
the safe transportation of fireworks. Furthermore, PHMSA's decision to 
incorporate by reference the updated APA Standard 87-1 is based on its 
review of the requirements for consumer fireworks in APA Standard 87-
1A, display fireworks in APA Standard 87-1B, and professional fireworks 
(classed as articles pyrotechnics) in APA Standard 87-1C. These 
standards add numerous new devices, expand the permitted chemical list, 
and are directed toward hazard classification for transportation. PHMSA 
is also clarifying that in incorporating Appendix I of each of APA 
Standards 87-1A, B, and C, it will adopt a one-percent manufacturing 
tolerance for the application of the chemical constituent limits in 
updated APA Standard 87-1. This would mean that for individual chemical 
constituents, an increase or decrease of one-percent of that material's 
share of the composition compared to the limits set forth in the 
updated APA Standard will be permitted for chemicals (other than red 
phosphorous and silver fulminate).
    PHMSA expects its incorporation of the updated APA Standard 87-1 
will provide cost savings to the fireworks industry by streamlining the 
EX approval process for many types of pyrotechnic devices. The EX 
approval processes within the updated APA Standard 87-1 will relieve 
the burden of submitting new fireworks designs to a third-party test 
lab for classification--a compliance cost often borne by distributors 
and small business importers, who often must contract to assist foreign 
manufacturing sources in obtaining EX approvals for their manufactured 
products. In addition, PHMSA expects that the incorporation of the 
revised APA standards will provide opportunities for the fireworks 
industry to work with the Department of Defense in developing 
incendiary type devices for training exercises. PHMSA estimates that 
adoption of this petition would provide an annualized cost savings of 
approximately $270,000 to industry through expediting the approval 
process to reduce explosives lab testing requirements. A more detailed 
discussion of the economic analysis can be found in the accompanying 
RIA.

V. Section-by-Section Review

    Below is a section-by-section description of the amendments in this 
final rule.

1. Appendix A to Part 107, Subpart D

    Appendix A to Part 107, Subpart D sets forth the guidelines PHMSA 
uses (as of October 2, 2013) in making initial baseline determinations 
for civil penalties. In this final rule, PHMSA is updating the 
references to APA Standard 87-1 to reflect the new edition of this 
standard.

2. Section 107.402

    Section 107.402 outlines how to apply for designation as a 
certification agency. PHMSA is updating the references to the APA 
Standard 87-1 to reflect the new edition of this standard in Sec.  
107.402(d).

3. Section 171.7

    Section 171.7 lists all standards incorporated by reference into 
the HMR that are not specifically set forth in the regulations. In this 
final rule, PHMSA is incorporating by reference the following 
publications by the APA, ASME, CGA, EU, and AESC/IME:

Ver. 02, dated September 1, 2017, into Sec.  173.67. The AESC/IME JPG 
Standard was developed by IME, AESC, and PHMSA to provide an efficient 
and economical mechanism to obtain explosives approvals of JPGs in 
compliance with the HMR. Applications that are prepared and submitted 
using the standard are processed by PHMSA with minimal delay and 
without the need for expensive and time-consuming testing.
     APA Standards: 87-1A Standard for the Construction, 
Classification, Approval and Transportation of Consumer Fireworks, 
January 1, 2018 edition into Sec. Sec.  107.402(d), 173.59, 173.64, 
173.65, and Appendix A to Part 107, Subpart D (Guidelines for Civil 
Penalties); 87-1B Standard for the Construction, Classification, 
Approval, and Transportation of Display Fireworks, January 1, 2018 
edition into Sec.  173.64 and Appendix C to Part 107, Subpart D 
(Guidelines for Civil Penalties); and 87-1C Standard for the 
Construction, Classification, Approval, and Transportation of 
Entertainment Industry and Technical (EI&T) Pyrotechnics, January 1, 
2018 edition version into Sec.  173.64 and Appendix A to Part 107, 
Subpart D (Guidelines for Civil Penalties). APA Standard 87-1A, B, and 
C is a consensus standard in which fireworks classifications are 
assigned based upon the weight and type of chemical composition 
contained for each specific type of device, including specific 
permissible and restricted chemicals.

4. Section 171.8

    Section 171.8 defines terms generally used throughout the HMR that 
have broad or multi-modal applicability. PHMSA is adding a definition 
for ``waste material'' to allow wastes that do not meet the EPA/RCRA 
definition of hazardous waste to be managed in accordance with the lab 
pack exception and associated paragraphs in Sec.  171.23.

5. Section 171.23

    Section 171.23 covers the requirements for specific materials and 
packagings transported under the ICAO Technical Instructions, IMDG 
Code, TC Transport of Dangerous Goods (TDG) Regulations, or the 
International Atomic Energy Agency (IAEA) Regulations. PHMSA is 
revising Sec.  171.23(a)(3) to allow for the use of pressure vessels 
and pressure receptacles that are marked with a pi mark in accordance 
with the European Directive 2010/35/EU on TPED and that comply with the 
requirements of Packing Instruction P200, P208 and 6.2 of ADR 
concerning PRD use, test period, filling ratios, test pressure, maximum 
working pressure, and material compatibility for the lading contained 
or gas being filled. This revision allows for import, intermediate 
storage, transport to point of use, discharge, and export of pi-marked 
cylinders. Note that since the publication of the NPRM, PHMSA has made 
minor editorial revisions to this section such as revising Sec.  
171.23(a)(3) to refer to 6.2.2. of the ADR instead of 6.2. PHMSA also 
removed the word ``import'' from Sec.  171.23(a)(3)(i) and ``export'' 
from Sec.  171.23(a)(3)(ii).

6. Section 172.101

    The HMT is contained in Sec.  172.101. The HMT lists 
alphabetically, by proper shipping name, those materials that have been 
designated hazardous materials for transportation purpose. It provides 
information used on shipping papers, package marking, and labeling, as 
well as other pertinent shipping information for hazardous materials. 
In this final rule, PHMSA is removing references to special provision 
103 from Column (7) of the HMT for the following four explosive 
entries: ``UN0361, Detonator assemblies, non-electric, for blasting''; 
``UN0365, Detonators for ammunition''; ``UN0255, Detonators, electric, 
for blasting''; and ``UN0267, Detonators, non-electric, for blasting.'' 
PHMSA is also revising more than 100 entries to harmonize the limited 
quantity exceptions in Column (8A) with the ICAO Technical Instructions 
and the UN Model Regulations.

7. Section 172.102

    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. Consistent 
with the Sec.  172.101 Column (7) revisions to ``UN0361, Detonator 
assemblies, non-electric, for blasting''; ``UN0365, Detonators for 
ammunition''; ``UN0255, Detonators, electric, for blasting''; and 
``UN0267, Detonators, non-electric, for blasting,'' PHMSA is removing 
special provision 103 as it would no longer apply to any HMT entry.

8. Section 172.302

    Section 172.302 describes the general marking requirements for bulk 
packagings. In this final rule, PHMSA is revising the minimum size of 
the marking requirement on certain portable tanks in Sec.  
172.302(b)(2). This revision requires a minimum marking of 12 mm (0.47 
inch) in height as applicable to portable tanks with capacities less 
than 3,785 L (1,000 gallons).

9. Section 173.5b

    Section 173.5b authorizes the transportation by highway of residual 
amounts of Division 2.2 refrigerant gases or anhydrous ammonia 
contained in non-specification pressure vessels that are components of 
refrigeration systems. PHMSA is revising paragraph (b) to indefinitely 
allow the use of refrigeration systems placed into service prior to 
June 1, 1991 under specified conditions.

10. Section 173.28

    Section 173.28 outlines the requirements for the reuse, 
reconditioning, and re-manufacture of packagings. In this final rule, 
PHMSA is modifying language in Sec.  173.28(c)(1)(i) to clarify 
requirements for reconditioning metal drums and to allow for the 
sufficient removal of external coatings to ensure there is no adverse 
effect on transportation safety.

11. Section 173.31

    Section 173.31 outlines the requirements for shipping hazardous 
materials in tank cars. In this final rule, PHMSA is prohibiting the 
use of tank cars that were manufactured using non-normalized steel for 
head or shell construction for the transportation of PIH materials 
after December 31, 2020. Furthermore, PHMSA is phasing out all non-HM-
246 compliant tank cars for the transportation of PIH materials by 
December 31, 2027.

12. Section 173.56

    Section 173.56 outlines the definitions and procedures for the 
classification and approval of a new explosive. In this final rule, 
PHMSA is adding a reference to the new Sec.  173.67, which would apply 
to exceptions for Division 1.1 JPGs.

13. Section 173.59

    Section 173.59 outlines the description of terms for explosives. In 
this final rule, PHMSA is updating a reference to the APA documents in 
the definition of consumer fireworks.

[[Page 75696]]

14. Section 173.64

    Section 173.64 outlines the exceptions for Division 1.3 and 1.4 
fireworks. In this final rule, PHMSA is updating a reference to the APA 
documents in Sec.  173.64(a)(1) and (3).

15. Section 173.65

    Section 173.65 outlines the exceptions for Division 1.4G consumer 
fireworks. In this final rule, PHMSA is updating a reference to the APA 
documents in Sec.  173.65(a)(1), (a)(3)(i), and (a)(4)(iv).

16. Section 173.67

    In this final rule, PHMSA is adding a new Sec.  173.67 to outline 
exceptions for Division 1.1 JPGs.

17. Section 173.151

    Section 173.151 outlines exceptions for Class 4 materials. In this 
final rule, PHMSA is revising the limited quantities provisions in this 
section to present limited quantities in appropriate SI units in liters 
in addition to kilograms.

18. Section 173.244

    Section 173.244 outlines the requirements for bulk packaging for 
certain pyrophoric liquids, dangerous when wet (Division 4.3) 
materials, and poisonous liquids with inhalation hazards (Division 
6.1). In this final rule, PHMSA is modifying the list of authorized 
tank car specifications in the table of PIH materials (Sec.  
173.244(a)(2)) by replacing the delimiter ``I'' with ``W'' to reflect 
the change of the interim tank car standard to a permanent standard.

19. Section 173.302

    Section 173.302 outlines the requirements for the filling of 
cylinders with nonliquefied (permanent) compressed gases or adsorbed 
gases. In this final rule, PHMSA is revising Sec.  173.302(a)(1) to 
refer to exceptions in Sec.  171.23(a)(3) for the importation of pi-
marked cylinders. PHMSA is also revising Sec.  173.302(a)(2) to make 
adsorbed gases eligible for the exceptions provided in Sec.  
171.23(a)(3).

20. Section 173.304

    Section 173.304 outlines the requirements for the filling of 
cylinders with liquefied compressed gases. In this final rule, PHMSA is 
revising Sec.  173.304(a) to refer to exceptions in Sec.  171.23(a)(3) 
for the importation of pi-marked cylinders.

21. Section 173.308

    Section 173.308 outlines the requirements for the shipment of 
lighters. In this final rule, PHMSA is deleting Sec.  173.308(d)(3), 
which requires a closed transport vehicle or closed freight container 
being transported by vessel to contain the marking, ``WARNING--MAY 
CONTAIN EXPLOSIVE MIXTURES WITH AIR--KEEP IGNITION SOURCES AWAY WHEN 
OPENING.''

22. Section 173.314

    Section 173.314 outlines the requirements for transporting 
compressed gases in tank cars and multi-unit tank cars. In this final 
rule, PHMSA is modifying the table in Sec.  173.314(c), which lists the 
authorized tank car specifications for specific compressed gases. The 
changes replace the last specification delimiter ``J'' with ``H'' and 
``I'' with ``W'' to reflect the change of the interim HM-246 tank car 
specification standard for PIH materials to a permanent standard.

23. Section 178.35

    Section 178.35 prescribes the manufacturing and testing 
specifications for cylinders used for the transportation of hazardous 
materials in commerce. In this final rule, PHMSA is modifying Sec.  
178.35(b) and (c) to clarify inspection requirements as stipulated in 
CGA C-11. This includes revision to the inspector duties as consistent 
with CGA C-11.

24. Section 178.521

    Section 178.521 prescribes the requirements for paper bags used as 
non-bulk packagings for hazardous materials. In this final rule, PHMSA 
is revising Sec.  178.521(b)(4) to allow for a weight tolerance of 
10 percent from the nominal basis weight reported in the 
initial design qualification test report instead of 5 
percent.

25. Section 179.22

    Section 179.22 specifies additional marking requirements for tank 
cars. In this final rule, PHMSA is modifying Sec.  179.22(e) to provide 
for new markings for tank cars manufactured after March 16, 2009, to 
meet the requirements of Sec. Sec.  173.244(a)(2) or (3) or 173.314(c) 
or (d) to reflect the change of the interim tank car standard to a 
permanent standard. PHMSA is replacing ``I'' with ``W'' for cars 
manufactured before the effective date of this final rule and 
specifying that tank cars manufactured after the effective date will be 
marked with ``W'' following the test pressure and with a delimiter of 
``H.''

26. Section 180.209

    Section 180.209 specifies requirements for requalification of 
specification cylinders. In this final rule, PHMSA is modifying Sec.  
180.209(l)(2) to reference Sec.  171.23(a)(5) in lieu of paragraph (4).

27. Section 180.213

    Section 180.213 specifies requirements for requalification 
markings. In this final rule, PHMSA is modifying Sec.  180.213(d)(2) to 
reference Sec.  171.23(a)(5) in lieu of paragraph (4).

28. Section 180.417

    Section 180.417 prescribes the reporting and record retention 
requirements pertaining to cargo tanks. Currently, Sec. Sec.  
180.417(a)(3)(i) and (ii) allow the use of alternative reports when a 
manufacturer's certificate and related papers are not available for DOT 
specification cargo tanks that were manufactured before September 1, 
1995. In this final rule, PHMSA is removing the provision that limits 
use of alternative reports to those DOT specification cargo tanks 
``manufactured before September 1, 1995'' from Sec.  180.417(a)(3).

VI. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This rulemaking is published under the authority of Federal 
hazardous materials transportation law \36\ (Federal hazmat law.). 
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.'' The Secretary's authority regarding hazardous 
materials safety is delegated to PHMSA at 49 CFR 1.97. This rulemaking 
amends several sections of the HMR in response to petitions for 
rulemaking received from the regulated community.
---------------------------------------------------------------------------

    \36\ 49 U.S.C. 5101 et seq.
---------------------------------------------------------------------------

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 E.O. 12866, ``Regulatory Planning and Review'' 
\37\ and, therefore, was not formally reviewed by the Office of 
Management and Budget (OMB). This rulemaking is also not considered a 
significant rulemaking under the DOT regulations governing rulemaking 
procedures at 49 CFR part 5, subpart B. E.O. 12866 requires agencies to 
regulate in the ``most cost-effective manner,'' to make a ``reasoned 
determination that the benefits of the intended regulation justify its 
costs,'' and to develop

[[Page 75697]]

regulations that ``impose the least burden on society.'' Similarly, DOT 
regulations at Sec.  5.5(f)-(g) require that regulations issued by 
PHMSA and other DOT Operating Administrations ``should be designed to 
minimize burdens and reduce barriers to market entry whenever possible, 
consistent with the effective promotion of safety'' and should 
generally ``not be issued unless their benefits are expected to exceed 
their costs.''
---------------------------------------------------------------------------

    \37\ 58 FR 51735 (Oct. 4, 1993).
---------------------------------------------------------------------------

    In addition, E.O. 12866 and DOT implementing regulations at 49 CFR 
5.5(i) require PHMSA to provide a meaningful opportunity for public 
participation, which also reinforces requirements for notice and 
comment under the Administrative Procedure Act. Therefore, in the NPRM, 
PHMSA sought public comment on its proposed revisions to the HMR, the 
preliminary cost and cost savings analyses in the Preliminary RIA, as 
well as any information that could assist in quantifying the benefits 
of this rulemaking. Those comments are addressed in this final rule, 
and additional discussion about the economic impacts of the final rule 
are provided within the RIA posted in the docket.
    In this final rule, PHMSA is introducing amendments to the HMR 
responding to 24 petitions that have been submitted by stakeholders. 
Overall, this rulemaking maintains the continued safe transportation of 
hazardous materials while producing a net cost savings. PHMSA estimates 
a present value of quantified net cost savings of approximately $0.72 
million annualized at a 7 percent discount rate over a perpetual time 
horizon. These estimates do not include non-monetized and qualitative 
cost/cost savings discussed in the RIA.
    PHMSA's cost/cost savings analysis relies on the monetization of 
impacts for three petitions included in this rulemaking. The following 
table presents a summary of the three petitions that would have 
monetized impacts upon codification and contribute to PHMSA's 
estimation of quantified net cost savings.

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

    In addition to those three items, this rulemaking amends the HMR in 
response to other petitions that are either (1) cost neutral or (2) 
deregulatory in nature in that they provide relief from unnecessary 
requirements or provide additional flexibility, but which have not been 
monetized due to information gaps preventing quantification of cost 
savings. Furthermore, PHMSA's actions in this final rule provide 
regulatory certainty to industry and allow efficient movement of 
hazardous materials resulting in increased economic activity.
    PHMSA's findings are described in further detail in the RIA posted 
in the docket.

C. Executive Order 13771

    This final rule is a deregulatory action under E.O. 13771, 
``Reducing Regulation and Controlling Regulatory Costs.'' \38\ Details 
on the estimated cost savings of this final rule can be found in the 
RIA posted in the docket.
---------------------------------------------------------------------------

    \38\ 82 FR 9339 (Jan. 30, 2017).
---------------------------------------------------------------------------

D. Executive Order 13132

    This rulemaking was analyzed in accordance with the principles and 
criteria contained in E.O. 13132, ``Federalism'', \39\ and the 
presidential memorandum (``Preemption'') that was published in the 
Federal Register. \40\ E.O. 13132 requires agencies to assure 
meaningful and timely input by State and local officials in the 
development of regulatory policies that may have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.'' This 
rulemaking may preempt State, local, and Tribal requirements, but does 
not propose any regulation that has substantial direct effects on the 
States, the relationship between the national government and the 
States, or the distribution of power and responsibilities among the 
various levels of government. Therefore, the consultation and funding 
requirements of E.O. 13132 do not apply.
---------------------------------------------------------------------------

    \39\ 64 FR 43255 (Aug. 10, 1999).
    \40\ 74 FR 24693 (May 22, 2009).
---------------------------------------------------------------------------

    The Federal hazmat law contains an express preemption provision, 49 
U.S.C. 5125(b), that preempts State, local, and Indian Tribal 
requirements on the following subjects:
    (1) The designation, description, and classification of hazardous 
materials;
    (2) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous materials;
    (3) The preparation, execution, and use of shipping documents 
related to hazardous materials 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, marking, maintenance, 
recondition, repair, or testing of a packaging or container 
represented, marked, certified, or sold as qualified for use in 
transporting hazardous material.
    This final rule addresses covered certain of the subject items 
above and preempts State, local, and Indian Tribe requirements 
concerning those subjects unless the non-Federal requirements are 
``substantively the same'' as the Federal requirements. PHMSA received 
no comments on the NPRM regarding the effect of the adoption of the 
specific proposals on State, local or tribal governments.

E. Executive Order 13175

    This rulemaking was analyzed in accordance with the principles and 
criteria contained in E.O. 13175, ``Consultation and Coordination with 
Indian Tribal Governments'' \41\ and DOT Order 5301.1, ``Department of

[[Page 75698]]

Transportation Policies, Programs, and Procedures Affecting American 
Indians, Alaska Natives, and Tribes.'' E.O. 13175 requires agencies to 
assure meaningful and timely input from Tribal government 
representatives in the development of rules that significantly or 
uniquely affect Tribal communities by imposing ``substantial direct 
compliance costs'' or ``substantial direct effects'' on such 
communities or the relationship and distribution of power between the 
Federal Government and Tribes. PHMSA assessed the impact of the 
rulemaking on Indian Tribal communities and determined that it would 
not significantly or uniquely affect Tribal communities or Indian 
Tribal governments. Therefore, the funding and consultation 
requirements of E.O. 13175 do not apply. Further, PHMSA did not receive 
comments on the Tribal implications of the rulemaking.

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

    The Regulatory Flexibility Act \42\ requires agencies to consider 
whether their rulemakings will have a ``significant economic impact on 
a substantial number of small entities'' to include small businesses, 
not-for-profit organizations that are independently owned and operated 
and are not dominant in their fields, and governmental jurisdictions 
with populations under 50,000. This rulemaking has been developed in 
accordance with E.O. 13272, ``Proper Consideration of Small Entities in 
Agency Rulemaking,'' \43\ and DOT implementing regulations at 49 CFR 
5.13(f) to ensure compliance with the Regulatory Flexibility Act 
requirements regarding evaluation of potential impacts of draft rules 
on small entities.

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

    1. Need for and objectives of the final rule.
    This final rule amends miscellaneous provisions in the HMR in 
response to 24 petitions for rulemaking. While maintaining safety, this 
final rule would amend certain requirements that are overly burdensome 
and provide clarity and flexibility where requested by the regulated 
community. The changes are generally intended to provide relief to 
shippers, carriers, and packaging manufacturers, including small 
entities.
    2. Significant issues raised by the public comments, a statement of 
the assessment by PHMSA regarding such issues, and a statement of any 
changes made in the proposed rule as a result of such comments.
    PHMSA did not receive any public comments suggesting that the 
proposed amendments would have a significant impact on small entities. 
Please refer to Section IV. (Discussion of Amendments and Applicable 
Comments) above and the RIA for PHMSA's responses to comments submitted 
in the rulemaking docket.
    3. PHMSA's response to any comments of the Chief Counsel for 
Advocacy of the Small Business Association (SBA).
    PHMSA received no comments filed by the SBA in response to the 
NPRM, and therefore has introduced no changes to this final rule in 
response.
    4. An estimate of the number of small entities to which the rule 
will apply or an explanation of why no such estimate is available.
    This final rule affects numerous small entities across a wide range 
of industries. However, quantified impacts on entities, large or small, 
could only be assessed for a few of the changes incorporated in this 
final rule due to data limitations. These impacts are explained, 
discussed and assessed in the accompanying RIA. For the purposes of 
identifying affected small entities, PHMSA focused on the industries 
for which quantified impacts could be estimated. PHMSA assumes that any 
change that did not draw comment from the industry and could not be 
quantified is unlikely to have a significant economic or other impact 
on small entities. PHMSA therefore limits the discussion here to the 
three items for which impacts could be quantified: (1) The adoption of 
petition P-1688 adopting a wider range of basis weight for the paper 
stock used to manufacture UN specification paper sacks; (2) P-1710 
adopting a new AESC/IME standard for JPGs; and (3) P-1711 incorporating 
by reference an updated APA Standard 87-1 pertaining to fireworks.
    The table below presents the U.S. Census Bureau Statistics of U.S. 
Businesses (SUBS) revenue data for each relevant NAICS Code that could 
be affected by incorporating P-1688.

                                         Manufacturing.
----------------------------------------------------------------------------------------------------------------

    Depending on the industrial sector, the SBA defines small entities 
either by a revenue threshold or by the number of employees. As 
identified in the accompanying RIA, the entities affected by the 
adoption of petition P-1688 are in North American Industrial 
Classification System (NAICS) code 322220--Paper Bag and Coated and 
Treated Paper Products Manufacturing. Firms in this NAICS sector 
manufacture a wide range of products, of which only a small subset are 
shipping sacks or shipping sack feed stock. Data are not available that 
would enable PHMSA to identify how many firms within the larger NAICS 
manufacture both shipping sacks and feed stock for shipping sacks, much 
less identify the number of small entities. Neither can PHMSA estimate 
the revenues for those small entities with any degree of certainty. As 
noted in the RIA, the high-end cost savings estimate is roughly 
$160,000 in cost savings per year. PHMSA does not believe these modest 
cost savings, spread among all affected manufacturers, would rise to 
the level of a significant impact for affected small entities.
    The second industry to consider is associated with petition P-1710 
and affects manufacturers of JPGs. As described in the RIA, there are 
five NAICS sectors that manufacture, operate or contract JPG services. 
These sectors include:
 NAICS Code 325920, Explosives Manufacturing
 NAICS Code 213111, Drilling Oil and Gas Wells
 NAICS Code 213112, Support Activities for Oil and Gas 
Operations

[[Page 75699]]

 NAICS Code 333132, Oil and Gas Field Machinery and Equipment 
Manufacturing
 NAICS Code 423830, Industrial Machinery and Equipment Merchant 
Wholesalers

    The RIA quantifies impacts related to elimination of testing 
requirements. The entities most directly impacted by this elimination 
are manufacturers of JPGs. While the firms involved in drilling wells, 
and equipment wholesalers, and support activities for oil and gas 
operations may use JPGs they are unlikely to manufacture them. PHMSA 
therefore uses NAICS codes 325920 and 333132 to identify the entities 
most likely to be affected by the cost savings associated with the 
changes associated with adoption of this petition. The small business 
size threshold for NAICS 325920--Explosives Manufacturing--is fewer 
than 750 employees. For NAICS 333132 the threshold for a small business 
is fewer than 1,250 employees. Given the size threshold for NAICS 
333132--Oil and Gas Field Machinery and Equipment Manufacturing, and 
looking at the Census Bureau SUBS tables, for this NAICS, it seems 
likely that virtually all firms in this industry qualify as small 
businesses. The average number of employees per firm with 500 employees 
or more is essentially 500 employees, indicating that even the largest 
firms in this industry are not much larger than 500 employees. Given 
that the threshold is more than double 500 employees, it seems 
reasonable to assume that essentially all firms in this industry fall

    The other NAICS under consideration (Explosives Manufacturing) has 
a threshold of 750 employees. 15 of the 52 firms in this sector have 
more than 500 employees. Again, it appears likely that the larger firms 
are clustered nearer the 500-employee threshold and hence would qualify 
as small businesses given a threshold of 750 employees.
    Both industrial sectors manufacture a wide range of products: 
Explosives range from munitions, to fireworks, demolitions explosives, 
etc. JPGs make up a small fraction of the product output for these 
firms. Similarly, there is a wide range of drilling and other equipment 
manufactured for oil and gas exploration, of which JPGs make up a small 
fraction. Given the nature of the data available from the Census Bureau 
or other sources, PHMSA is unable to identify the number of firms in 
either of these broader industrial sectors that manufacture JPGs, much 
less those that would qualify as small entities. Nor could PHMSA 
identify revenues for small entities for use in making a significance 
determination with any degree of certainty. Although PHMSA cannot 
determine the number of JPG manufacturers or their revenues with any 
degree of specificity, PHMSA does not believe that the cost savings 
would amount to a significant impact on small entities, as estimated 
cost savings would be $360,000 split among all manufacturers of JPGs.
    PHMSA concludes by evaluating the last provision of this final rule 
for which it has quantified the economic impacts: That element 
responding to petition P-1711 by incorporating an updated edition of 
APA Standard 87-1 by reference. This provision is the only element of 
the NPRM that drew adverse comments. These adverse comments are 
addressed above in the preamble. To summarize PHMSA's response, the 
items that drew the most concern appear to be unchanged from the 
existing regulatory requirements. Insofar as that is the case, the 
negative consequences for small entities alleged by the comments on the 
NPRM do not result from adoption of the updated APA Standard 87-1.
    PHMSA did quantify some cost savings related to testing fireworks 
associated with adoption of the updated APA Standard 87-1. These cost 
savings result from reducing UN series 5 and 6 testing requirements for 
certain classes of fireworks. As described in the RIA, PHMSA estimated 
that this change may reduce testing costs by roughly $270,000 per year. 
Such a reduction in costs would be to the benefit of the fireworks 
industry, and PHMSA does not interpret these cost savings to be 
significant.
    As described in the RIA, virtually all consumer fireworks, and 
roughly 75 percent of display fireworks, are manufactured in China. The 
RIA describes the U.S. fireworks industry as having about $1.2 billion 
in revenue, of which consumer fireworks revenues account for about $885 
million and display fireworks account for the remaining $353 million.
    Fireworks manufacturers fall into a miscellaneous NAICS code--NAICS 
325998--All Other Miscellaneous Chemical Product and Preparation 
Manufacturing. Fireworks manufacturing makes up a small fraction of the 
economic activity in this industry, which has a total revenue of 
roughly $22 billion according to the Census Bureau SUBS data. The SBA 
size threshold for this industry is 500 employees: Firms with fewer 
than 500 employees are defined as small entities and those with 500 or 
more employees are not defined as small entities. The table below 
presents the relevant SUBS data for this NAICS code.

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

    As with other sectors assessed in this section, PHMSA cannot 
estimate the number of entities within the broader NAICS category that 
manufacture fireworks. The NAICS category in question contains firms 
that manufacture a wide range of products, only one small subset of 
which are fireworks. Given the lack of data with more detailed 
specificity, PHMSA cannot identify firms that manufacture fireworks, 
much less identify small entities that manufacture fireworks, or 
estimate revenue for those small entities. Given the relatively modest 
estimate of $270,000 in annual cost savings, and that those savings 
would be split among multiple firms, PHMSA does not expect the impacts 
to be significant.
    5. A description of the projected reporting, recordkeeping and 
other compliance requirements of the rule, including an estimate of the 
classes of small entities which will be subject to the requirement and 
the type of professional skills necessary for preparation of the report 
or record.
    There are no reporting or recordkeeping requirements under the 
``Paperwork Reduction Act'' associated with this final rule.
    6. Alternative proposals for small entities.
    The Regulatory Flexibility Act directs agencies to establish 
exceptions and differing compliance standards for small entities, where 
it is possible to do so and still meet the objectives of the applicable 
regulatory statutes.
    To the extent that PHMSA received adverse comments, they were not 
targeted at alleviating burdens on small entities. While PHMSA may 
consider guidance to the extent that it is necessary to help clarify 
responsibilities for small entities, PHMSA does not expect that 
establishing exceptions to the HMR amendments in this final rule or 
alternative requirements for small entities to address potential 
concerns about the impact on small entities would accomplish the safety 
objectives of Federal hazmat law. Moreover, many of the HMR amendments 
introduced in this final rule--insofar as they relate to or incorporate 
by reference technical specifications or industry standards--do not 
accommodate different regulatory approaches based on whether the entity 
is small entity or not. Further, as explained at length in Section IV. 
(Discussion of Amendments and Applicable Comments) of this final rule, 
the HMR amendments introduced in this final rule are generally 
deregulatory in nature and intended to provide reduce regulatory 
burdens on small entities and other members of the regulated community.
    7. Conclusion.
    The changes in this final rule are generally intended to provide 
relief to shippers, carriers, and packaging manufactures and testers, 
including small entities. As discussed above, a shortage of pertinent 
data prevents PHMSA from quantifying economic impacts on small entities 
potentially affected by most of the HMR amendments introduced in this 
final rule. However, PHMSA has developed estimates for the numbers of 
small businesses that may be affected by the HMR revisions introduced 
in this final rule for which PHMSA has provided quantified cost 
benefits. For those HMR amendments, PHMSA has compared cost savings 
impacts to average small entity annual revenue and in none of those 
cases does an impact rise to even 1 percent of average small entity 
revenue, and in all cases the impacts reduce costs for the entities 
affected. Therefore, PHMSA determines that this final rule will not 
have a significant economic impact on a substantial number of small 
entities.

G. Paperwork Reduction Act

    PHMSA has analyzed this final rule in accordance with the Paperwork 
Reduction Act of 1995.\44\ This final rule does not impose new 
information collection requirements. PHMSA did not receive any comments 
regarding information collection activities under this final rule.

H. Regulation Identifier Number (RIN)

    A regulation identifier number (RIN) is assigned to each regulatory 
action listed in the Unified Agenda of Federal Regulatory and 
Deregulatory Actions (Unified Agenda). The Regulatory Information 
Service Center publishes the Unified Agenda in April and October of 
each year. The RIN contained in the heading of this final rule can be 
used to cross-reference this action with the Unified Agenda.

I. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act (UMRA) \45\ requires agencies to 
prepare a written assessment of the costs, benefits, and other effects 
of proposed or final rules that include a Federal mandate likely to 
result in the expenditure by State, local, or Tribal governments, in 
the aggregate, or by the private sector, of $100 million or more 
annually, adjusted for inflation. A Federal mandate is defined, in 
part, as a regulation that imposes an enforceable duty upon State, 
local, or Tribal governments or would reduce or eliminate the amount of 
authorization of appropriation for Federal financial assistance that 
would be provided to State, local, or Tribal governments for the 
purpose of complying with a previous Federal mandate.
---------------------------------------------------------------------------

    \45\ 2 U.S.C. 1501 et seq.
---------------------------------------------------------------------------

    This final rule does not impose unfunded mandates under the UMRA. 
It does not result in costs of $100 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 (NEPA) \46\ requires 
Federal agencies to consider the consequences of major Federal actions 
and prepare a detailed statement on actions significantly affecting the 
quality of the human environment. The Council on Environmental Quality 
(CEQ)

[[Page 75701]]

implementing regulations (40 CFR part 1500-1508) require Federal 
agencies to conduct an environmental review considering (1) the need 
for the action, (2) a description of the action and alternatives, (3) 
probable environmental impacts of the action and alternatives, and (4) 
comments from the public and the agencies and persons consulted during 
the consideration process. DOT Order 5610.1C, ``Procedures for 
Considering Environmental Impacts,'' establishes departmental 
procedures for evaluation of environmental impacts under NEPA and its 
implementing regulations.
---------------------------------------------------------------------------

    \46\ 42 U.S.C. 4321 et seq.
---------------------------------------------------------------------------

    PHMSA has completed its NEPA analysis. Based on the environmental 
assessment herein, PHMSA determined that an environmental impact 
statement is not required for this final rule because the HMR 
amendments introduced will not result in a significant environmental 
impact requiring the preparation of an environmental impact statement. 
PHMSA notes that it received no comments from the public on the NEPA 
analysis within the NPRM.
1. Need for the Action
    PHMSA is amending the HMR in response to petitions for rulemaking 
submitted by the regulated community to update, clarify, or provide 
relief from miscellaneous regulatory requirements. PHMSA expects that 
the HMR revisions in this final rule will provide cost benefits to the 
regulated community without adversely affecting safety. PHMSA has 
provided a brief summary of each of those HMR revisions, including 
their impact on safety, in Section IV (Discussion of Amendments and 
Applicable Comments) of this final rule.
2. Alternatives
    In this rulemaking, PHMSA considered the following alternatives:
Alternative 1: No Action
    The No Action Alternative would not proceed with a rulemaking on 
any of the previously-accepted petitions for rulemaking submitted by 
stakeholders. In the No Action Alternative, current HMR provisions 
would remain in effect.
Alternative 2: Amend the HMR as Provided in This Final Rule
    The Final Rule Alternative would adopt the HMR amendments set forth 
in this final rule.
3. Environmental Impacts
    Hazardous materials are substances that may pose a threat to public 
safety or the environment during transportation because of their 
physical, chemical, or nuclear properties. Under the HMR, hazardous 
materials are transported by aircraft, vessel, rail, and highway. The 
HMR embodies a risk management approach that is prevention-oriented and 
focused on identifying a safety hazard and reducing the probability and 
quantity of a hazardous material release. The potential for 
environmental damage or contamination exists when packages of hazardous 
materials are involved in accidents or en route incidents resulting 
from cargo shifts, valve failures, package failures, loading, 
unloading, collisions, handling problems, or deliberate sabotage. The 
release of hazardous materials can cause the loss of ecological 
resources (e.g., wildlife habitats) and the contamination of air, 
aquatic environments, and soil. Contamination of soil can lead to the 
contamination of ground water. Compliance with the HMR substantially 
reduces the possibility of accidental release of hazardous materials, 
thereby minimizing the potential a significant impact on public health 
and the environment.
Alternative 1: No Action
    If PHMSA were to select the No Action Alternative, current 
regulations would remain in place. However, efficiencies gained through 
harmonization of HMR provisions with international (UN, ICAO, IMDG, and 
EU) and consensus standards (AAR, APA, ASME, CGA, IME) for domestic 
U.S. industry would not be realized, thereby foregoing cost and safety 
benefits identified in Section IV. (Discussion of Amendments and 
Applicable Comments) of this final rule. Consistency between HMR 
requirements and international regulations and updated industry 
standards can promote the safety of international hazardous materials 
transportation through a better understanding of HMR requirements, an 
increased level of industry compliance, and fewer disruptions in 
transport of hazardous materials from their points of origin to their 
points of destination. Each of those consequences promote protection of 
human health and the environment; they also result in decreased 
compliance costs for regulated entities.
    Nor, moreover, would the No Action Alternative provide meaningful 
safety benefits in declining to adopt HMR revisions in this final rule 
affording regulated entities greater flexibility in complying with HMR 
requirements. As explained in greater detail in Section IV. (Discussion 
of Amendments and Applicable Comments) PHMSA does not expect those 
flexibility-affording HMR amendments in the final rule (including, but 
not limited to, extension of regulatory exceptions to additional 
commodities; relaxation of labelling requirements or cleaning 
requirements) to adversely affect safety. Further, the regulatory 
flexibilities foregone in the No Action Alternative do not exist in 
isolation: Rather, they are each backstopped by the robust, proven 
safety framework provided by other HMR requirements governing the 
transportation of hazardous materials.
Alternative 2: Go Forward With the Proposed Amendments to the HMR in 
This Final Rule
    PHMSA selected the Final Rule Alternative as the preferred 
alternative. The Final Rule Alternative updates, clarifies, or provides 
relief from a variety of HMR regulatory requirements. As explained at 
greater length in Section IV (Discussion of Amendments and Applicable 
Comments) of this final rule and the above discussion of the No Action 
Alternative, PHMSA expects the Final Rule Alternative will realize cost 
benefits from providing greater compliance flexibility for regulated 
entities without adversely affecting safety. Further, PHMSA expects 
cost and safety benefits from harmonizing HMR requirements with 
international and domestic U.S. industry standards can also promote 
safety, thereby minimizing the risk of environmental impacts from the 
release of hazardous materials to the environment during shipment. For 
example, the Final Rule Alternative's regulatory phase out of legacy-
specification PIH tank cars consistent with industry (AAR) consensus 
standards and contractual practices (e.g., interchange rules) 
permanently locks-in the safety benefits associated with a more robust 
tank car design for transporting PIH material.
    The table below summarizes the anticipated environmental impacts 
from each of the elements of the final rule alternative:

4. Agencies consulted
    PHMSA expects this final rule would affect hazardous materials 
shippers and carriers by highway, rail, vessel, and aircraft, as well 
as package manufacturers and testers. PHMSA sought therefore sought 
comment from the following Federal Agencies and modal partners:

 Federal Aviation Administration
 Federal Motor Carrier Safety Administration
 Federal Railroad Administration
 U.S. Coast Guard

    PHMSA did not receive any adverse comments on the amendments in 
this final rule from these or any other Federal Agencies.
5. Conclusion
    PHMSA finds that no significant environmental impacts will result 
from this final rule. The revisions in the final rule are intended to 
update, clarify, or provide relief from certain existing HMR 
requirements by eliminating unnecessary regulatory requirements; 
aligning HMR requirements with international and industry standards; 
and introducing editorial clarifications to make HMR requirements 
easier to understand. PHMSA does not expect those HMR revisions to 
adversely impact safety, much less cause a significant environmental 
impact under NEPA.

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 http://www.regulations.gov, as described in the 
system of records notice (DOT/ALL-14 FDMS), which can be reviewed at

L. Executive Order 13609 and International Trade Analysis

    Under E.O. 13609, ``Promoting International Regulatory 
Cooperation,'' \47\ 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.
---------------------------------------------------------------------------

    \47\ 77 FR 26413 (May 4, 2012).
---------------------------------------------------------------------------

    Similarly, the Trade Agreements Act of 1979,\48\ as amended by the 
Uruguay Round Agreements Act,\49\ 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.
---------------------------------------------------------------------------

    \48\ Public Law 96-39.
    \49\ Public Law 103-465.
---------------------------------------------------------------------------

    PHMSA participates in the establishment of international standards 
to protect the safety of the American public. PHMSA has assessed the 
effects of the rulemaking to ensure that it does not cause unnecessary 
obstacles to foreign trade. As explained in greater detail in Section 
IV. (Discussion of Amendments and Applicable Comments) of the preamble 
to this final rule, several of the HMR amendments introduced in this 
rulemaking better align U.S. requirements for transportation of 
hazardous materials with international (e.g., UN, IMDG) standards. 
Further, insofar as those and other HMR amendments in this final rule 
are expected to reduce regulatory burdens, improve the clarity of HMR 
provisions, and afford regulated entities greater flexibility in 
satisfying HMR requirements, PHMSA expects the final rule to make a 
positive contribution to U.S. domestic and international trade. 
Accordingly, this final rule is consistent with E.O. 13609 and PHMSA's 
obligations under the Trade Agreement Act, as amended.

M. Executive Order 13211

    E.O. 13211, ``Actions Concerning Regulations That Significantly 
Affect Energy Supply, Distribution, or Use'' \50\ requires Federal 
agencies to prepare a Statement of Energy Effects for any ``significant 
energy action.'' Under E.O. 13211, a ``significant energy action'' is 
defined as any action by an agency

[[Page 75703]]

(normally published in the Federal Register) that promulgates, or is 
expected to lead to the promulgation of, a final rule or regulation 
(including a notice of inquiry, ANPRM, and NPRM) that: (1)(i) Is a 
significant regulatory action under E.O. 12866 or any successor order, 
and (ii) is likely to have a significant adverse effect on the supply, 
distribution, or use of energy; or (2) is designated by the 
Administrator of the Office of Information and Regulatory Affairs as a 
significant energy action.
---------------------------------------------------------------------------

    \50\ 66 FR 28355 (May 22, 2001).
---------------------------------------------------------------------------

    This final rule is not significant energy action as contemplated by 
E.O. 13211. It is neither a ``significant regulatory action'' under 
E.O. 12866, nor expected to have a significant adverse effect on the 
supply, distribution or use of energy in the United States. The 
Administrator of OIRA has not designated the final rule as a 
significant energy action.

N. National Technology Transfer and Advancement Act

    The National Technology Transfer and Advancement Act of 1995 \51\ 
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 standards bodies. This final rule incorporates 
updates to multiple voluntary consensus standards which are listed in 
Sec.  171.7. See Section II, ``Incorporation by Reference Discussion 
Under 1 CFR part 51'' for availability.

Canada TDG Regulations, or the IAEA Regulations.

* * * * *
    (a) Conditions and requirements for cylinders and pressure 
receptacles--(1) Applicability. Except as provided in this paragraph 
(a), a filled cylinder (pressure receptacle) manufactured to other than 
a DOT specification or a UN standard in accordance with part 178 of 
this subchapter, a DOT exemption or special permit cylinder, a TC, CTC, 
CRC, or BTC cylinder authorized under Sec.  171.12, or a cylinder used 
as a fire extinguisher in conformance with Sec.  173.309(a) of this 
subchapter, may not be transported to, from, or within the United 
States.
    (2) Conditions. Cylinders (including UN pressure receptacles) 
transported to, from, or within the United States must conform to the 
applicable requirements of this subchapter. Unless otherwise excepted 
in this subchapter, a cylinder must not be transported unless--
    (i) The cylinder is manufactured, inspected and tested in 
accordance with a DOT specification or a UN standard prescribed in part 
178 of this subchapter, or a TC, CTC, CRC, or BTC specification set out 
in the Transport Canada TDG Regulations (IBR, see Sec.  171.7), except 
that cylinders not conforming to these requirements must meet the 
requirements in paragraph (a)(3), (4), or (5) of this section;
    (ii) The cylinder is equipped with a pressure relief device in 
accordance with Sec.  173.301(f) of this subchapter and conforms to the 
applicable requirements in part 173 of this subchapter for the 
hazardous material involved;
    (iii) The openings on an aluminum cylinder in oxygen service 
conform to the requirements of this paragraph, except when the cylinder 
is used for aircraft parts or used aboard an aircraft in accordance 
with the applicable airworthiness requirements and operating 
regulations. An aluminum DOT specification cylinder must have an 
opening configured with straight (parallel) threads. A UN pressure 
receptacle may have straight (parallel) or tapered threads provided the 
UN pressure receptacle is marked with the thread type, e.g. ``17E, 25E, 
18P, or 25P'' and fitted with the properly marked valve; and
    (iv) A UN pressure receptacle is marked with ``USA'' as a country 
of approval in conformance with Sec. Sec.  178.69 and 178.70 of this 
subchapter, or ``CAN'' for Canada.
    (3) Pi-marked pressure receptacles. Pressure receptacles that are 
marked with a pi mark in accordance with the European Directive 2010/
35/EU (IBR, see Sec.  171.7) on transportable pressure equipment (TPED) 
and that comply with the requirements of Packing Instruction P200 or 
P208 and 6.2 of ECE/TRANS/257 (Vol. I), the Agreement Concerning the 
International Carriage of Dangerous Goods by Road (ADR) (IBR, see Sec.  
171.7) concerning pressure relief device use, test period, filling 
ratios, test pressure, maximum working pressure, and material 
compatibility for the lading contained or gas being filled, are 
authorized as follows:
    (i) Filled pressure receptacles imported for intermediate storage, 
transport to point of use, discharge, and export without further 
filling; and
    (ii) Pressure receptacles imported or domestically sourced for the 
purpose of filling, intermediate storage, and export.
    (iii) The bill of lading or other shipping paper must identify the 
cylinder and include the following certification: ``This cylinder 
(These cylinders) conform(s) to the requirements for pi-marked 
cylinders found in 171.23(a)(3).''
    (4) Importation of cylinders for discharge within a single port 
area. Except as provided in Sec.  171.23(a)(3), a cylinder manufactured 
to other than a DOT specification or UN standard in accordance with 
part 178 of this subchapter, or a TC, CTC, BTC, or CRC specification 
cylinder set out in the Transport Canada TDG Regulations (IBR, see 
Sec.  171.7), and certified as being in conformance with the 
transportation regulations of another country may be authorized, upon 
written request to and approval by the Associate Administrator, for 
transportation within a single port area, provided--
    (i) The cylinder is transported in a closed freight container;
    (ii) The cylinder is certified by the importer to provide a level 
of safety at least equivalent to that required by the regulations in 
this subchapter for a comparable DOT, TC, CTC, BTC, or CRC 
specification or UN cylinder; and
    (iii) The cylinder is not refilled for export unless in compliance 
with paragraph (a)(5) of this section.
    (5) Filling of cylinders for export or for use on board a vessel. A 
cylinder not manufactured, inspected, tested and marked in accordance 
with part 178 of this subchapter, or a cylinder manufactured to other 
than a UN standard, DOT specification, exemption or special permit, or 
other than a TC, CTC, BTC, or CRC specification, may be filled with a 
gas in the United States and offered for transportation and transported 
for export or alternatively, for use on board a vessel, if the 
following conditions are met:
    (i) The cylinder has been requalified and marked with the month and 
year of requalification in accordance with subpart C of part 180 of 
this subchapter, or has been requalified as authorized by the Associate 
Administrator;
    (ii) In addition to other requirements of this subchapter, the 
maximum filling density, service pressure, and pressure relief device 
for each cylinder conform to the requirements of this part for the gas 
involved; and
    (iii) The bill of lading or other shipping paper identifies the 
cylinder and includes the following certification: ``This cylinder has 
(These cylinders have) been qualified, as required, and filled in 
accordance with the DOT requirements for export.''
    (6) Cylinders not equipped with pressure relief devices. A DOT 
specification or a UN cylinder manufactured, inspected, tested and 
marked in accordance with part 178 of this subchapter and otherwise 
conforms to the requirements of part 173 of this subchapter for the gas 
involved, except that the cylinder is not equipped with a pressure 
relief device may be filled with a gas and offered for transportation 
and transported for export if the following conditions are met:
    (i) Each DOT specification cylinder or UN pressure receptacle must 
be plainly and durably marked ``For Export Only'';
    (ii) The shipping paper must carry the following certification: 
``This cylinder has (These cylinders have) been retested and refilled 
in accordance with the DOT requirements for export.''; and
    (iii) The emergency response information provided with the shipment 
and available from the emergency response telephone contact person must 
indicate that the pressure receptacles are not fitted with pressure 
relief devices and provide appropriate guidance for exposure to fire.

Notes to table 1 to paragraph (c): 1. The percent filling density for liquefied gases is hereby defined as the
  percent ratio of the mass of gas in the tank to the mass of water that the tank will hold. For determining the
  water capacity of the tank in kilograms, the mass of 1 L of water at 15.5 [deg]C in air is 1 kg. (the mass of
  one gallon of water at 60 [deg]F in air is 8.32828 pounds).
2. The liquefied gas must be loaded so that the outage is at least two percent of the total capacity of the tank
  at the reference temperature of 46 [deg]C (115 [deg]F) for a noninsulated tank; 43 [deg]C (110 [deg]F) for a
  tank having a thermal protection system incorporating a metal jacket that provides an overall thermal
  conductance at 15.5 [deg]C (60 [deg]F) of no more than 10.22 kilojoules per hour per square meter per degree
  Celsius (0.5 Btu per hour/per square foot/per degree F) temperature differential; and 41 [deg]C (105 [deg]F)
  for an insulated tank having an insulation system incorporating a metal jacket that provides an overall
  thermal conductance at 15.5 [deg]C (60 [deg]F) of no more than 1.5333 kilojoules per hour per square meter per
  degree Celsius (0.075 Btu per hour/per square foot/per degree F) temperature differential.
3. The requirements of Sec.   173.24b(a) apply.

[[Page 75716]]

 
4. The gas pressure at 54.44 [deg]C (130 [deg]F.) in any non-insulated tank car may not exceed \7/10\ of the
  marked test pressure, except that a tank may be charged with helium to a pressure 10 percent in excess of the
  marked maximum gas pressure at 54.44 [deg]C (130 [deg]F.) of each tank.
5. The liquid portion of the gas at -17.77 [deg]C (0 [deg]F.) must not completely fill the tank.
6. The maximum permitted filling density is 125 percent. The quantity of chlorine loaded into a single unit-tank
  car may not be loaded in excess of the normal lading weights nor in excess of 81.65 Mg (90 tons).
7. 89 percent maximum to 80.1 percent minimum at a test pressure of 6.2 Bar (90 psig).
8. 59.6 percent maximum to 53.6 percent minimum at a test pressure of 7.2 Bar (105 psig).
9. For a liquefied petroleum gas, the liquefied gas must be loaded so that the outage is at least one percent of
  the total capacity of the tank at the reference temperature of 46 [deg]C (115 [deg]F) for a noninsulated tank;
  43 [deg]C (110 [deg]F) for a tank having a thermal protection system incorporating a metal jacket that
  provides an overall thermal conductance at 15.5 [deg]C (60 [deg]F) of no more than 10.22 kilojoules per hour
  per square meter per degree Celsius (0.5 Btu per hour/per square foot/per degree F) temperature differential;
  and 41 [deg]C (105 [deg]F) for an insulated tank having an insulation system incorporating a metal jacket that
  provides an overall thermal conductance at 15.5 [deg]C (60 [deg]F) of no more than 1.5333 kilojoules per hour
  per square meter per degree Celsius (0.075 Btu per hour/per square foot/per degree F) temperature
  differential.
10. For liquefied petroleum gas and anhydrous ammonia, during the months of November through March (winter), the
  following reference temperatures may be used: 38 [deg]C (100 [deg]F) for a noninsulated tank; 32 [deg]C (90
  [deg]F) for a tank having a thermal protection system incorporating a metal jacket that provides an overall
  thermal conductance at 15.5 [deg]C (60 [deg]F) of no more than 10.22 kilojoules per hour per square meter per
  degree Celsius (0.5 Btu per hour/per square foot/per degree F) temperature differential; and 29 [deg]C (85
  [deg]F) for an insulated tank having an insulation system incorporating a metal jacket and insulation that
  provides an overall thermal conductance at 15.5 [deg]C (60 [deg]F) of no more than 1.5333 kilojoules per hour
  per square meter per degree Celsius (0.075 Btu per hour/per square foot/per degree F) temperature
  differential. The winter reference temperatures may only be used for a tank car shipped directly to a consumer
  for unloading and not stored in transit. The offeror of the tank must inform each customer that the tank car
  was filled based on winter reference temperatures. The tank must be unloaded as soon as possible after March
  in order to retain the specified outage and to prevent a release of hazardous material which might occur due
  to the tank car becoming liquid full at higher temperatures.
11. For materials poisonous by inhalation, the single unit tank car tanks authorized are only those cars
  approved by the Tank Car Committee for transportation of the specified material and built prior to March 16,
  2009.
12. Except as provided by paragraph (d) of this section, for materials poisonous by inhalation, fusion-welded
  tank car tanks built on or after March 16, 2009 used for the transportation of the PIH materials noted, must
  meet the applicable authorized tank car specification and must be equipped with a head shield as prescribed in
  Sec.   179.16(c)(1).
