I. Executive Summary

    In response to petitions for rulemaking submitted by the regulated 
community, PHMSA is amending the Hazardous Materials Regulations (HMR; 
49 CFR parts 171-180) to update, clarify, streamline, or provide relief 
from miscellaneous regulatory requirements. Specifically, PHMSA is:
     Incorporating by Reference (IBR) multiple publications 
from the Compressed Gas Association (CGA), the Chlorine Institute, and 
the Department of Defense (DoD).
     Revising the table in Sec.  180.407(g)(1)(iv) to make this 
section consistent with the applicable packaging specification (e.g., 
Sec.  178.347).
     Addressing inconsistencies with domestic and international 
labels and placards.
     Revising Sec.  173.150(g) include the use of the 
International System of Units (SI).
     Excepting limited quantities of ``UN1942, Ammonium 
nitrate'' from requiring permission from the Captain of the Port (COTP) 
before being loaded or unloaded from a vessel at a waterfront facility.
     Allowing for combination non-bulk packagings that are 
tested and marked for a liquid hazardous material to be filled with a 
solid hazardous material.
     Including an additional hazardous material description for 
transport in roadway striping vehicles.
     Extending the service life of interim compliant toxic 
inhalation hazard (TIH) tank cars to the full service life of all other 
tank cars.
     Allowing the use of plastic, metal, or composite pallets 
to transport materials classed and marked as limited quantities.
     No longer mandating that excepted quantities comply with 
the emergency response telephone requirement.
     Harmonizing the recordkeeping requirements for portable 
tanks.
     Allowing for printing tolerances for labels and placards.
     Allowing electronic signatures for Environmental 
Protection Agency (EPA) manifest forms.
     No longer requiring the service pressure to be marked on 
Department of Transportation (DOT) 8 and 8L cylinders.
     Acknowledging that the marked date of manufacture on a 
composite intermediate bulk container (IBC) may differ from the marked 
date of manufacture on the inner receptacle of that IBC.
     Revising the basis weight tolerance for fiberboard boxes 
from +/- 5% to +/- 10% from the nominal basis weight reported in the 
initial design qualification test report.

II. Background

A. Notice of Proposed Rulemaking

    On June 30, 2016, PHMSA (also ``we'' or ``us'') published in the 
Federal Register a notice of proposed rulemaking (NPRM) titled, 
``Hazardous Materials: Miscellaneous Petitions for Rulemaking (RRR)'' 
under Docket No. PHMSA-2016-0102 (HM-219A). This deregulatory 
rulemaking action is part of PHMSA's retrospective review efforts that 
are designed to identify ways to improve the HMR.

[[Page 55793]]

    The Administrative Procedure Act (APA) requires Federal agencies to 
give interested persons the right to petition an agency to issue, 
amend, or repeal a rule. See 5 U.S.C. 553(e). PHMSA's rulemaking 
procedure regulations in 49 CFR 106.95 establish a process for persons 
to ask PHMSA to add, amend, or delete a regulation by filing a petition 
for rulemaking containing adequate support for the requested action. 
The HM-219A NPRM responded to 19 petitions for rulemaking submitted to 
PHMSA by various stakeholders. In the NPRM, we proposed to amend the 
HMR to update, clarify, or provide relief from miscellaneous regulatory 
requirements at the request of the regulated community.
    PHMSA received 26 public comments in response to the above 
amendments proposed in the June 30, 2016 NPRM. These comments are 
discussed in further detail in this final rule.

B. Commenters

    The comment period for the June 30, 2016, NPRM closed on August 29, 
2016. PHMSA received a total of 26 comments from 25 separate entities, 
seven of which submitted petitions discussed in the NPRM. PHMSA 
developed this final rule in consideration of the comments received to 
the public docket. The comments submitted to this docket may be 
accessed via http://www.regulations.gov. The following persons, 
companies, and associations submitted comments to the HM-219A NPRM:

III. Discussion of Amendments and Applicable Comments

    Section III discusses the proposals that are being adopted, as well 
as those not being adopted, into the HMR as part of this rulemaking.

A. General Comments

    This final rule, and the NPRM that preceded it, are part of PHMSA's 
retrospective regulatory review efforts, and is in response to 
petitions for rulemaking by the regulated community. Its intent is to 
update, clarify, or provide relief from miscellaneous regulatory 
requirements. The NPRM provided an opportunity for further public 
participation in the development of the regulatory amendments and 
promoted exchange of information and perspectives among the various 
stakeholders.
    PHMSA received comments from 25 entities. The comments were 
comprehensive and raised important issues to be addressed. PHMSA fully 
considered all comments in the development of this final rule. This 
final rule preamble contains a detailed description of the original 
proposals in the June 30, 2016 NPRM, a summary of the comments 
received, a response to those comments, and an explanation of PHMSA's 
decisions for each petition proposed in the NPRM.

B. Comments Beyond the Scope of This Rulemaking

    This section discusses the comments to the HM-219A NPRM that 
provided suggestions for additional revisions that were not 
specifically addressed in the NPRM. Based on an assessment of the 
proposed changes and the comments received, PHMSA identified two 
comments as beyond the scope of this rulemaking action.
    PHMSA received a comment from the Association of American Railroads 
(AAR) related to petition P-1646 and the phase out of tank cars 
constructed of non-normalized steel. While PHMSA has accepted this 
petition for a future rulemaking, it is not being addressed in this 
final rule. PHMSA will use AAR's comments if a future NPRM is developed 
on the referenced petition P-1646.
    PHMSA also received a comment from Mr. Adam Adamczyk, who suggested 
that PHMSA incorporate by reference numerous standards from the 
American National Standards Institute (ANSI), American Society of 
Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE), 
American Society for Testing and Materials (ASTM), and the American 
Welding Society (AWS). PHMSA did not propose the incorporation of these 
standards in the NPRM and thus is not incorporating the standards in 
this final rule. However, PHMSA suggests the commenter submit a 
petition in accordance with Sec.  106.95 of the HMR for any IBR 
standards the

[[Page 55794]]

commenter would suggest including in a future rulemaking.

C. Provisions Not Adopted in This Final Rule and Discussion of Comments

    This section discusses the changes proposed in the NPRM that are 
not being adopted in this final rule. In the preamble to the NPRM, 
PHMSA inadvertently included a section on petition P-1655 from the 
Dangerous Goods Trainers Association (DGTA). PHMSA did not propose any 
regulatory text and is therefore not addressing this petition at this 
time. PHMSA anticipates addressing this petition in a future 
rulemaking.

D. Provisions Adopted in This Final Rule and Discussion of Comments

    This section discusses the changes proposed in the NPRM and the 
comments received in response. Based on an assessment of the proposed 
changes and the comments received, PHMSA is adopting the following 
provisions in this final rule. Also, to clearly identify the issues 
addressed in this rule, PHMSA provides the following list of adopted 
amendments discussed in this section:
1. Cargo Tank Specification
    In petition P-1615, The Walker Group requested revisions to the 
table in Sec.  180.407(g)(1)(iv) to make this section consistent with 
the applicable packaging specification (e.g., Sec.  178.347). A cargo 
tank manufactured to the requirements of the applicable DOT 
specifications has to be tested in accordance with the HMR. Currently, 
the design specifications for cargo tanks in Sec.  178.320 contain 
general requirements applicable to all cargo tanks. The design 
specifications, including the test pressures for older cargo tanks that 
are no longer authorized for manufacture but still authorized for use, 
were last found in the 1985 edition of the HMR (e.g., MC 306--Sec.  
178.341-7; MC 307--Sec.  178.342-7; MC 312--Sec.  178.343-7).
    This petition seeks to eliminate confusion by changing the 
regulations to allow the use of the marked test pressure on the cargo 
tank nameplate as the requalification test pressure and to amend every 
entry in the Sec.  180.407(g)(1)(iv) test pressure table by beginning 
the entries with the phrase, ``[t]he test pressure on the nameplate 
(specification plate).'' PHMSA conducted a technical and policy review 
of the petition. Instead of modifying every test pressure entry as 
suggested by the petitioner, PHMSA proposed in the NPRM that revisions 
should only apply to certain cargo tank specifications (DOT 407, MC 
304, and MC 307) to harmonize the periodic hydrostatic testing required 
by part 180 with the initial testing for the applicable packaging 
specification prescribed in part 178. The proposed revisions aimed to 
further clarify that test pressures (in case of periodic pneumatic 
testing required by part 180) are already consistent with the initial 
testing for the applicable packaging specification prescribed in part 
178.
    In response to the proposal, PHMSA received comments from Daniel 
Shelton, Truck Trailer Manufacturers Association (TTMA), and National 
Propane Gas Association (NPGA). NPGA noted a discrepancy in the 
preamble text and proposed regulatory text. Specifically, NPGA 
referenced the preamble text that identifies revisions to certain cargo 
tank specifications for hydrostatic testing of DOT 407, MC 304, and MC 
307. However, NPGA noted that the proposed regulatory text adds the 
increased test pressure for all cargo tanks, rather than just those 
specifications identified in the preamble. NPGA requested that PHMSA 
resolve the discrepancy to ensure it is consistent with both the 
administration and the petitioner's intent. PHMSA agrees with the 
commenter and is adding to each entry the phrase, ``The test pressure 
on the name plate or specification plate, or 1.5 times the MAWP, 
whichever is greater.''
    Daniel Shelton requested PHMSA adopt the increased test pressure 
requirements for MC 306 cargo tanks in addition to the proposed 
language. Specifically, the suggestion stemmed from industry confusion 
on the appropriate test pressure that should be used for cargo tanks. 
PHMSA agrees and, as stated above, is adding the revised language to 
all entries in Sec.  180.407(g)(1)(iv).
    TTMA supported the petition and the proposed amendment but noted a 
minor error in the table for the DOT 412 entry. TTMA believed this note 
should read: ``[t]he test pressure on the name plate or specification 
plate, or 1.5 times the MAWP, whichever is greater.'' PHMSA agrees with 
TTMA and is adding ``or'' as appropriate to the table in Sec.  
180.407(g)(1)(iv).
2. Chlorine Institute Publications
    In petition P-1619, the Chlorine Institute requested that updates 
to publications currently listed in Sec.  171.7(l)--specifically Sec.  
171.7(l)(1), (2), (5), and (12)--and referenced in various sections of 
the HMR be incorporated by reference. PHMSA conducted a review of these 
publications and found them suitable to propose incorporation into the 
HMR. In the NPRM, PHMSA proposed to include the following updated 
documents in the referenced material:
     Chlorine Institute Emergency Kit ``A'' for 100-lb. & 150-
lb. Chlorine Cylinders, Edition 12, Revision 2, July 2014. Emergency 
Kit ``A'' is designed for use with the standard DOT 3A480 and 3AA480 
100 and 150-pound capacity cylinders in chlorine service only. 
Emergency Kit ``A'' contains devices and tools to contain leaks in and 
around the cylinder valve and in the side wall of chlorine cylinders. 
The Chlorine Institute Emergency Kit ``A'' is the only chlorine 
emergency kit for chlorine cylinders that is manufactured to the design 
specifications of the Chlorine Institute. Under certain circumstances 
U.S. DOT regulations permit transportation of a chlorine cylinder with 
an Emergency Kit ``A''. See 49 CFR 173.3(e).
     Chlorine Institute Emergency Kit ``B'' for Chlorine Ton 
Containers, Edition 11, Revision 1, July 2014. Emergency Kit ``B'' is 
designed for use with the standard DOT 106A500X chlorine ton container 
and can also be used with 110A500W in chlorine service. Emergency Kit 
``B'' contains devices and tools to contain leaks in and around the ton 
container valves and in the side wall of ton containers. The Chlorine 
Institute Emergency Kit ``B'' is the only chlorine emergency kit for 
ton containers that is manufactured to the design specifications of The 
Chlorine Institute. Under certain circumstances U.S. DOT regulations 
permit transportation of a chlorine ton container with an Emergency Kit 
``B''. See 49 CFR 173.3(e).
     Pamphlet 57, Emergency Shut-Off Systems for Bulk Transfer 
of Chlorine, Edition 6, June 2015. This pamphlet covers the recommended 
practices for emergency shut-off protection during chlorine transfers 
involving bulk containers.
     Pamphlet 168, Guidelines for Dual Valve Systems for Bulk 
Chlorine Transport, Edition 2, July 2015. The purpose of this pamphlet 
is to set forth performance/selection criteria that should be utilized 
in identifying dual valve systems for bulk chlorine transportation 
applications (i.e., tank cars, cargo tanks and barges). These 
configurations are intended to meet U.S. Department of Transportation 
(DOT) and Transport Canada (TC) performance requirements. This pamphlet 
contains information pertaining to standardizations, performance/design 
criteria, operational considerations and installation considerations, 
as well as an

[[Page 55795]]

appendix that includes valve manufacturer information.
    PHMSA received comments from the Chlorine Institute in relation to 
this petition. The Chlorine Institute supported PHMSA's incorporation 
of the IBR documents. The Chlorine Institute further believed that this 
would eliminate the need for certain special permits (specifically SP-
16102, which allows transportation of equipment designed in accordance 
with Edition 11, Revision 1, of the Emergency Kit ``B'' (B-Kit) 
instruction booklet). PHMSA agrees and is therefore adopting the 
changes in Sec.  171.7(l) to incorporate the most recent Chlorine 
Institute publications as proposed.
3. International Label and Placard Consistency
    In petition P-1620, Labelmaster Services requested revisions to the 
HMR to address inconsistencies between international and domestic 
labels and placards. Specifically, the petition requested revisions to 
Sec. Sec.  172.519(f) and 172.407(f) of the HMR to allow for the use of 
labels and placards conforming to the specifications in the United 
Nations Recommendations on the Transport of Dangerous Goods (UN 
Recommendations), the International Civil Aviation Organization 
Technical Instructions on the Safe Transport of Dangerous Goods by Air 
(ICAO Technical Instructions), the International Maritime Dangerous 
Goods (IMDG) Code, or the Transport Canada Transportation of Dangerous 
Goods (TDG) Regulations.
    Upon reviewing the petition, PHMSA found that the requested changes 
are likely to clarify some regulatory requirements and provisions that 
exist for the transportation of hazardous materials internationally, 
and are not likely to be onerous or costly for the regulated community. 
In the NPRM, PHMSA proposed revisions to Sec. Sec.  172.519(f) and 
172.407(f) of the HMR to allow for the use of labels and placards 
conforming to the specifications in the UN Recommendations, ICAO 
Technical Instructions, IMDG Code, or TDG Regulations.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from Clifford Bartley, Council on the Safe Transport of 
Hazardous Articles (COSTHA), and International Vessel Operators 
Dangerous Goods Association (IVODGA). All commenters expressed support 
for PHMSA adopting these provisions as written. Additionally, COSTHA 
added that the proposed changes would not increase the burden on 
shippers. PHMSA agrees with the commenters and is therefore 
incorporating the changes in Sec. Sec.  172.519(f) and 172.407(f) of 
the HMR as proposed.
4. Limited Quantities of Ammonium Nitrate by Vessel
    In petition P-1624, Horizon Lines, LLC requested that Sec.  
176.415(b) be revised to except limited quantities of ``UN1942, 
Ammonium nitrate'' from requiring permission from the Captain of the 
Port (COTP) before being loaded or unloaded from a vessel at a 
waterfront facility. This petition for rulemaking is in response to 
previous changes to the HMR that will eliminate the Other Regulated 
Materials Domestic (ORM-D) classification.
    Specifically, Horizon Lines expressed concern that while the change 
from ORM-D to limited quantities is good for harmonization and the 
industry overall, the change has had some unintended negative 
consequences for shippers and vessel operators. Specifically, Horizon 
Lines identified having to reclassify ``UN1942, Ammonium nitrate'' 
products that would have previously shipped as ORM-D as being shipped 
under the limited quantities exception. Horizon Lines believes the HMR 
requires that ``UN1942, Ammonium nitrate, 5.1'' be moved under a United 
States Coast Guard (USCG) permit regardless of the quantity shipped.
    Upon review of the petition, PHMSA found that shipping ``UN1942, 
Ammonium nitrate, 5.1'' as a limited quantity instead of ORM-D will put 
a higher burden of cost on both the shipper and the vessel operator, 
without increasing safety, because they must continue to abide by the 
requirements in Sec.  176.415(c)(4) to obtain a permit. Section 
176.415(b) already provides exceptions for ``UN1942, Ammonium nitrate'' 
when shipped in a rigid packaging with a noncombustible inside 
packaging and ``UN2067, Ammonium nitrate fertilizer'' when the nearest 
COTP is notified at least 24 hours in advance of any loading or 
unloading in excess of 454 kg (1,000 pounds). In the NPRM, PHMSA 
proposed an exception for ``UN1942, Ammonium nitrate'' when shipped as 
a limited quantity to require written notification to the USCG at least 
24 hours prior to loading this type of cargo.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from Clifford Bartley, Institute of Makers of Explosives 
(IME), COSTHA, and IVODGA. All commenters expressed support for PHMSA 
adopting these provisions. However, IME disagreed that the proposed 
exception should only apply to ``limited quantities'' of ``UN1942, 
Ammonium nitrate fertilizer.'' IME recommended that PHMSA extend the 
proposed exception to any amount of UN1942, not just limited 
quantities.
    IME's comment is outside the scope of the petition. One of the main 
justifications for supporting P-1624 was limiting the scope of the 
exception to ``limited quantities,'' as these materials were previously 
classed ORM-D at the same quantity limits and therefore were exempt 
from Sec.  176.11(e). It is also unclear from the comment what IME is 
proposing or why any exemptions should apply regardless of whether or 
not they are limited quantities.
5. Use of Combination Packages Tested With a Liquid
    In petition P-1625, HAZMATPAC requested the allowance of the 
shipment of solid materials in a package when that package has been 
tested with a liquid material. Currently, Sec.  173.24a(b)(3) allows a 
single or composite non-bulk packaging that is tested and marked for a 
liquid hazardous material to be filled with a solid hazardous material 
up to a gross mass in kilograms not exceeding the rated capacity of the 
packaging in liters, multiplied by the specific gravity of the 
packaging, or 1.2 if not marked. In addition, paragraphs (i), (ii), and 
(iii) allow a packaging rated for a liquid Packing Group (PG) I to be 
filled with a solid PG II hazardous material, a packaging rated for a 
liquid PG I to be filled with a solid PG III hazardous material, and a 
packaging rated for a liquid PG II to be filled with a solid PG III 
hazardous material.
    In the NPRM, PHMSA proposed to revise Sec.  173.24a(b)(3) to allow 
combination packages tested with liquids to transport solid materials. 
In response to the proposed changes in the NPRM, PHMSA received 
comments from COSTHA, Dangerous Goods Advisory Council (DGAC), Reusable 
Industrial Packaging Association (RIPA), and Donald Hausmann. Mr. 
Hausmann supported the proposed requirement, stating that these 
revisions would improve shipping options for solid material shippers 
without hindering safety concerns. In its comments, COSTHA stated it 
cannot support or oppose the proposed revision, as further 
clarification is needed on PHMSA's intentions for revising Sec.  
173.24a(b)(1) and (3). Specifically, COSTHA indicated that the proposed 
regulatory language erroneously compares specific gravity to the gross 
mass of the package and vice versa. COSTHA provided the following 
language, which they believe PHMSA

[[Page 55796]]

intended to incorporate in this section: ``A Packing Group I packaging 
may be used for a Packing Group II material with a specific gravity not 
exceeding the greater of 1.8, or 1.5 times the specific gravity marked 
on the packaging, or with the gross mass of the package not exceeding 
1.5 times the gross mass marked on the packaging, provided all the 
performance criteria can still be met with the higher specific gravity 
material.'' RIPA also noted that the proposed language to Sec.  173.24a 
as ``or gross mass of the package'' is inexact and confusing. RIPA 
commented that in most cases ``gross mass'' is not marked on package 
tested for a liquid. RIPA believed PHMSA should ensure that the upper 
limit of 400 kg net mass for the definition of non-bulk packages would 
not be exceeded when using this section. RIPA also noted that PHMSA 
specified in the preamble that the adoption of P-1625 was for 
combination packages; however, combination packages are not referenced 
in the proposed regulatory text of Sec.  173.24a. RIPA indicated their 
belief that combination packages were not eligible for filling 
provisions of solids in liquid rated packages because of safety 
concerns and that the exclusion of combination packages is correct if 
safety can be shown as a risk.
    PHMSA agrees with COSTHA's proposed language with respect to the 
gross mass of the package and is updating the language in this final 
rule to accurately reflect the intention of the NPRM. PHMSA is also 
adding a statement stating that ``packages shall not exceed 400 kg'' to 
ensure only non-bulk packages could be used in this section. PHMSA is 
also removing the text for single and composite (thus encompassing all 
non-bulk packages) to clarify that it was PHMSA's intent in the NPRM to 
allow for single, combination, and composite packages to be able to use 
this section. While RIPA did note some safety concerns with including 
combination packages in this section, PHMSA believes the concerns are 
unfounded. PHMSA believes the factors used to convert between the 
different packing groups correspond with the multiples between the drop 
test heights, accounting for the change in testing needed to certify a 
package for a greater weight at a lower packing group.
6. Shipping Names for Roadway Striping Vehicles
    In petition P-1634, 3M Company requested an amendment to the table 
in Sec.  173.5a(c)(l) to include an additional hazardous material 
description for transport in roadway striping vehicles. Specifically, 
3M requested the addition of UN2735 ``Amines, Liquid, Corrosive, 
n.o.s., 8, III'' or ``Polyamines, Liquid, Corrosive, n.o.s., 8, III'' 
when used as a catalyst.
    The table in Sec.  173.5a(c)(1) currently lists ``UN3267, Corrosive 
liquid basic, organic, n.o.s.'' as a catchall for corrosive liquids, 
while at the same time Sec.  172.101(c)(10)(iii) reads, ``[a] mixture 
or solution meeting the definition of one or more hazard class that is 
not identified in the Table specifically by name, comprised of two or 
more hazardous materials in the same hazard class, must be described 
using an appropriate shipping description (e.g., `Flammable liquid, 
n.o.s.').'' Further, commodities that can be described explicitly (not 
comprised of two or more hazardous materials) should be listed by ``the 
name that most appropriately describes the material,'' with the example 
being an alcohol not listed by its technical name in the table being 
described as ``Alcohol, n.o.s'' rather than ``Flammable liquid, 
n.o.s.'' Because an amine compound is the single hazardous corrosive 
component in 3M's pavement marking liquid, PHMSA believes this change 
will not result in measurable economic or safety impacts. In the NPRM, 
PHMSA proposed to add proper shipping names to the list of authorized 
materials in Sec.  173.5a(c)(1).
    PHMSA received no comments either supporting or opposing this 
proposal. Therefore, PHMSA is incorporating the changes to Sec.  
173.5a(c)(l) as proposed to allow the shipping descriptions ``UN2735, 
Amines, Liquid, Corrosive, n.o.s., 8, III'' or ``Polyamines, Liquid, 
Corrosive, n.o.s., 8, III'' when used as a catalyst.
7. Toxic by Inhalation Tank Car Lifespan
    In petition P-1636, the Chlorine Institute requested that PHMSA 
extend the service life of interim compliant toxic inhalation hazard 
(TIH) tank cars to the full service life of all other tank cars as 
allowed in Sec.  215.203 of the Federal Railroad Administration (FRA) 
regulations. Specifically, the Chlorine Institute requested a revision 
to paragraph Sec.  173.31(e)(2)(iii), which specifies a 20-year 
allowable service life for tank cars transporting TIH materials that 
were built to specifications contemplated in the HM-246 rulemaking 
because of an expected delay of at least 8 to 10 years before a 
permanent TIH design standard and specification would be available from 
the Advanced Tank Car Collaborative Research Program (ATCCRP).
    Although the plain language of Sec.  173.31(e)(2)(iii) limits the 
authorized service life of tank cars meeting the relevant 
specifications to 20 years from the date of the cars' construction, the 
final rule in which PHMSA adopted this 20-year service life made clear 
that tank cars built to these specifications were intended as an 
interim solution to then-existing market conditions. (74 FR 1770; Jan. 
13, 2009). These interim tank car specifications were intended to make 
immediate safety improvements in tank car construction and to ensure 
the ongoing availability of tank cars for the transportation of TIH 
materials while the Department moved forward with the development and 
validation of an enhanced performance standard for TIH tank cars and 
the incorporation of such an enhanced standard into the HMR. With the 
understanding of the interim nature of these cars, PHMSA intended the 
20-year authorized service life to guarantee tank car owners a 
reasonable service life for the cars, even if the Department were to 
issue a new tank car standard in the years immediately following the 
2009 final rule [74 FR 1770]. The Department is still working towards 
developing and implementing an enhanced performance standard for TIH 
materials tank cars. PHMSA's review of the petition found that there is 
likely economic merit in undertaking a rulemaking as requested. In the 
NPRM, PHMSA proposed to revise Sec.  173.31(e)(2)(iii) to remove the 
20-year service life, which will allow continued use of the interim 
compliant TIH tank cars to the full service life of all other tank 
cars, as allowed in Sec.  215.203.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from American Chemistry Council (ACC), Railway Supply 
Institute (RSI), Dow Chemical, Railway Supply Institute Committee on 
Tank Cars (RSICTC), and DGAC. All commenters expressed support to 
extend the service life of TIH tank cars as proposed. RSICTC added that 
extending the service life of the TIH tank cars would provide an 
economic incentive for further investment in tank cars with at least a 
50 percent improvement in crashworthiness. PHMSA agrees with the 
commenters and is therefore incorporating the changes in Sec.  
173.31(e)(2)(iii) to remove the 20-year service life, which will extend 
the use of the interim compliant TIH tank cars to the full service life 
of all other tank cars as allowed in Sec.  215.203.
    PHMSA received a petition for rulemaking (P-1691) from the American 
Association of Railroads (AAR)/The Chlorine Institute/American 
Chemistry Council (ACC)/The Fertilizer Institute/Railway Supply 
Institute (RSI) on December 16, 2016, requesting that PHMSA revise the 
HMR to make the

[[Page 55797]]

``interim'' tank car specifications issued as part of the HM-246 final 
rule be considered the ``final'' specifications. On September 18, 2017, 
PHMSA accepted the petition, and if a future NPRM is developed PHMSA 
will address the issue in that rulemaking. Please see the docket for P-
1691 \1\ for additional information.

8. Limited Quantity Pallets
    In petition P-1638, Labelmaster Services requested a revision to 
the HMR that would allow the use of plastic or metal pallets to 
transport materials classed and marked as limited quantities. The 
petition specifically requested that PHMSA revise Sec.  
173.156(b)(2)(iii), which specifies these materials be secured to a 
wooden pallet, to also specify that they could be secured to a plastic 
or metal pallet.
    PHMSA's review of the petition found that there is likely economic 
merit in undertaking a rulemaking as requested. In addition, a 
technical review of the petition found there should be no decrease in 
safety due to the proposed change. The changes suggested by this 
petition would allow transporters greater flexibility in their choice 
of pallets, with possible accompanying cost savings. In the NPRM, PHMSA 
proposed to revise Sec.  173.156(b)(2)(iii) to allow for the use of 
metal, plastic, or composite pallets used to ship limited quantities of 
hazardous materials.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from Healthcare Distribution Alliance (HDA), COSTHA, and DGAC. 
All commenters expressed support for the proposal. In addition, COSTHA 
specified that it should be reiterated that the hazardous materials 
should be compatible with the pallet material. PHMSA agrees and is 
revising Sec.  173.156(b)(2)(iii) to allow for the use of metal, 
plastic, or composite pallets to ship limited quantities of hazardous 
materials, provided the hazardous materials will not react with the 
pallet material.
9. Emergency Response Numbers
    In petition P-1639, Horizon Lines, LLC requested an exception to 
the requirement in Sec.  172.604(d)(1) to provide an emergency response 
telephone number, suggesting that an emergency response telephone 
number no longer be required on a shipping paper for excepted 
quantities of hazardous materials. This change would be consistent with 
how PHMSA treats limited quantities of hazardous materials. 
Specifically, the petitioner asked PHMSA to revise Sec.  172.604(d)(1) 
so that it may be applicable to limited quantities and excepted 
quantities.
    This modification is justified because excepted quantity weights 
are less than the already exempted limited quantity weights. In 
addition, this revision will harmonize the emergency response number 
requirements with the IMDG Code, which does not require an emergency 
response telephone number on the dangerous goods documentation (or 
anywhere else) for any excepted material; however, all hazardous 
materials, including those in excepted quantities, must comply with 
Section 5.4.3.2 of the IMDG Code, which requires emergency response 
information to be communicated in ways other than a phone number, such 
as a Safety Data Sheet (SDS). PHMSA's review of the petition found that 
there is likely economic merit in undertaking a rulemaking as requested 
without any decrease to safety. In the NPRM, PHMSA proposed to revise 
Sec.  172.604(d)(1) to no longer require an emergency response 
telephone number on a shipping paper be provided for excepted 
quantities of hazardous materials.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from AAR, COSTHA, IVODGA, DGAC, Clifford Bartley, the 
Fertilizer Institute (TFI), HAD, and the Chlorine Institute. All 
commenters expressed support for the proposal. Therefore, PHMSA is 
incorporating the changes to Sec.  172.604(d)(1) as proposed to no 
longer require an emergency response telephone number be provided on a 
shipping paper for excepted quantities of hazardous materials.
10. Units of Measurement for Limited Quantities of Ethyl Alcohol
    In petition P-1640, the Association of HAZMAT Shippers (AHS) 
requested that the units of measure included in Sec.  173.150(g), which 
addresses limited quantities of retail products containing ethyl 
alcohol, be converted to the International System of Units (SI units) 
because SI units are used elsewhere in the HMR. SI units are typically 
used in the manufacturing of inner receptacles. PHMSA's review of the 
petition found that there is likely economic merit in undertaking a 
rulemaking as requested without any decrease to safety. In the NPRM, 
PHMSA proposed to revise Sec.  173.150(g) to convert measurements to SI 
units.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from AHS, VWR International, LLC, and COSTHA. AHS expressed 
appreciation for incorporation of its petition, which addressed the 
lack of metric units in Sec.  173.150(g). However, AHS noted that the 
NPRM did not fully address the original petition, which further 
requested incorporation of the original scope of Special Permit 9275 
into Sec.  173.150(g) that included language allowing ``items suitable 
for retail sale'' to be included in the exception. PHMSA notes that in 
our response to AHS's petition, we denied the portion requesting the 
incorporation of the term ``suitable for retail'' sale in Sec.  
173.150(g). Therefore, PHMSA did not propose in the NPRM to include the 
terms ``suitable for retail sale'' and as such we are not incorporating 
the term ``suitable for retail sale'' in this final rule.
    AHS also commented that there are inconsistencies with the 
incorporation of SI units in Sec.  173.150(g). Specifically, AHS noted 
that as specified in Sec.  171.10, when SI units are displayed, they 
are the controlling standard, and when U.S. units appear in 
parentheses, they are for additional information. AHS noted that their 
petition originally requested that PHMSA incorporate SI units as the 
controlling standard and U.S. units in parentheses, which is opposite 
to the proposed language in the NPRM. Therefore, AHS requested that the 
intent of the original petition be incorporated. Furthermore, AHS, VWR 
International, LLC, and COSTHA provided conversions between SI and U.S. 
units, which they ask to be changed. PHMSA agrees with the commenters 
and is correcting the regulatory text in Sec.  173.150(g) to show the 
SI unit as the controlling units in this final rule.
11. Cylinder Valves and Protection Caps
    In petition P-1641, CGA proposed to add new paragraphs Sec.  
173.301(a)(11) and (12). The proposed changes concern valve 
requirements for cylinders as outlined in ``CGA V-9-2012, Compressed 
Gas Association Standard for Compressed Gas Cylinder Valves, Seventh 
Edition.'' Specifically, CGA requested that cylinder valves and 
cylinder valve protection caps manufactured on or after May 4, 2019, be 
required to conform to the requirements in ``CGA V-9-2012, Compressed 
Gas Association Standard for Compressed Cylinder Valves, Seventh 
Edition.'' Justifications for this request include ensuring 
standardization of cylinder valve designs and providing guidance to 
users on proper selection of valves. PHMSA's review of the petition 
found that there is likely economic merit in undertaking a rulemaking 
as requested without any decrease to safety. In the NPRM,

[[Page 55798]]

PHMSA proposed to add new paragraphs to Sec.  173.301(a)(11) and (12) 
to the HMR to conform to the new standards for cylinder valves and caps 
as outlined in ``CGA V-9-2012, Compressed Gas Association Standard for 
Compressed Gas Cylinder Valves, Seventh Edition.''
    In response to the proposed changes in the NPRM, PHMSA received 
comments from Dow Chemical, COSTHA, NPGA, and DGAC. While commenters 
expressed support for the proposed changes, DGAC and Dow were concerned 
that the proposed requirements may not be appropriate or feasible for 
materials identified under the Hazardous Materials Table (HMT) entries 
for ``chemical under pressure,'' such as UN3500 and UN3503. 
Specifically, DGAC noted that the valves may not be appropriate for 
dispensing liquids, since they are more suitable for dispensing a 
``true gas'' and may not be suitable for valves meeting CGA V-9-2012 
requirements. As an alternative to the proposed regulatory language, 
Dow suggested revising the requirement for CGA V-9-2012 valves to 
exclude ``chemical under pressure'' from the requirements. 
Alternatively, Dow suggested revising Sec.  173.335(a) to except these 
materials from the proposed requirements in Sec.  173.301(a)(11) and 
(12). In addition, Dow, DGAC, COSTHA, and NPGA requested a sufficient 
and significant delay to allow time to comply with the retrofit in 
replacing existing valves. DGAC noted that a May 4, 2015, retrofit date 
would cause significant cost to industry in order to replace stainless 
steel valves for these cylinders, with a cost estimate of approximately 
$2.3 million. COSTHA also commented that it is unclear if the second 
sentence in proposed Sec.  173.301(a)(11) and (12) provides mandatory 
exceptions for UN Pressure Receptacles or additional requirements.
    PHMSA's Office of Hazardous Materials Safety is revising the HMR to 
ensure that cylinder valves follow uniform construction and performance 
standards for improved transportation safety of cylinders containing 
hazardous materials. PHMSA agrees with commenters that an exception 
from the valve requirements should be made for those chemicals under 
pressure regulated under Sec.  173.335. Therefore, PHMSA is 
implementing Dow's proposal to revise the requirements for chemicals 
under pressure in Sec.  173.335(a) to provide an exception to conform 
to the new standards for cylinder valves and caps in the new 
requirements in Sec.  173.301(a)(11) and (12). PHMSA is also extending 
the compliance date to give a grace period of one year after the 
rulemaking becomes effective to comply with the new valve cap 
requirements in Sec.  173.301(a)(11) and (12). PHMSA is further 
clarifying that the second sentence in Sec.  173.301(a)(11) and (12) 
provides additional requirements for UN Pressure Receptacles.
    NPGA noted that CGA's petition states that Liquefied Petroleum Gas 
(LPG) cylinder valves and valve protection systems would not be 
affected by the adoption of CGA V-9-2012 because LPG cylinders are 
already listed by National Fire Protection Association (NFPA) 58. 
However, NPGA noted that NPFA 58 does not require cylinder valves to be 
listed but does require that they comply with ANSI 1769, which is 
different than being listed. Therefore, NPGA expressed concern that the 
adoption of CGA V-9-2012 would conflict with the cylinder valve 
requirement for cylinders used in LPG service under NFPA 58. NPGA also 
noted that the proposed regulatory text for Sec.  171.7 does not 
include CGA-V-9-2012.
    To address the concerns of NPGA, PHMSA is revising Sec.  
173.301(a)(11) to read: ``Cylinder valves used on cylinders in 
liquefied petroleum gas (LPG) service are permitted to comply with the 
requirements of NFPA 58, Liquefied Petroleum Gas Code.'' PHMSA also 
agrees that the CGA V-9-2012 standard should be cited in Sec.  171.7 
and is adding applicable regulatory text to this section.
12. Recordkeeping Requirements for Portable Tanks
    In petition P-1644, HAZMAT Resources proposed to add text to Sec.  
180.605(l) to address recordkeeping requirements for portable tanks. 
This revision would harmonize this recordkeeping requirement with Sec.  
180.417(a)(3)(ii), which addresses recordkeeping requirements for 
certain cargo tank motor vehicles constructed and certified in 
accordance with the ASME Code. The petitioner recommended renaming 
Sec.  180.605(l) as Sec.  180.605(l)(1) and adding an additional Sec.  
180.605(l)(2). This new section would include recordkeeping 
requirements in line with Sec.  180.417(a)(3)(ii). PHMSA agrees this 
revision as proposed would provide an alternative means of compliance 
for portable tanks that has already been provided for cargo tanks. 
PHMSA believes there is likely economic merit in revising this section 
without a reduction in safety. In the NPRM, PHMSA proposed to revise 
Sec.  180.605(l) to allow the owner of a portable tank to contact the 
National Board for a copy of the manufacturer's data report, if the 
portable tank was registered with the National Board, or copy the 
information contained on the portable tanks specification plate and 
ASME Code data plates.
    PHMSA received no comments either supporting or opposing this 
proposal. Therefore, PHMSA is incorporating the changes to Sec.  
180.605(l) as proposed to allow the owner of a portable tank to contact 
the National Board for a copy of the manufacturer's data report, if the 
portable tank was registered with the National Board, or copy the 
information contained on the portable tanks specification plate and 
ASME Code data plates.
13. Printing Tolerances for Labels and Placards
    In petition P-1650, Labelmaster Services proposed to revise 
Sec. Sec.  172.407(c) and 172.519(c) of the HMR to allow printing 
tolerances for labels and placards. Labelmaster noted that the printing 
tolerances specified for the solid-line inner border that is parallel 
to the edge is extremely difficult to maintain with standard printing 
processes.
    After a policy review of the petition, PHMSA agrees with 
Labelmaster that the absence of a tolerance will increase printing 
costs, as well as lead to inconsistent enforcement practices and 
confusion on the part of businesses attempting to remain compliant, 
without providing any increase in safety or hazard communication. In 
the NPRM, PHMSA proposed to revise Sec. Sec.  172.407(c) and 172.519(c) 
to add the word ``approximately'' to these sections to allow for 
printing tolerances with respect to the solid inner border for labels 
and placards. PHMSA believes that this simple fix and small change in 
the HMR could reduce costs with no degradation in safety.
    In response to the NPRM, PHMSA received comments from COSTHA and 
DGAC in support of the proposed changes. Therefore, PHMSA is revising 
Sec. Sec.  172.407(c) and 172.519(c) as proposed to add the word 
``approximately'' to these sections to allow for printing tolerances 
with respect to the solid inner border for labels and placards.
14. Incorporation of Department of Defense Standards
    In petition P-1651, the Department of Defense (DoD) Explosives 
Safety Board requested that PHMSA amend the citations in Sec.  
171.7(o)(1) and (2) to include the latest detailed publications used by 
the DoD in its examination and classification of explosives. PHMSA

[[Page 55799]]

reviewed and provided feedback to DoD on the proposed changes to the 
manuals. Updating this manual is essential to allowing the DoD to 
safely move explosives in the interest of national security.
    PHMSA received no comments either supporting or opposing this 
proposal. Therefore, PHMSA is incorporating the latest publications 
used by the DoD in its examination and classification of explosives in 
Sec.  171.7(o)(1) and (2) as proposed.
15. Service Pressure Marking for DOT 8 and DOT 8L Cylinders
    In petition P-1656, Norris Cylinder proposed that PHMSA revise 
Sec.  178.35(f)(7) to no longer require the marking of the service 
pressure on DOT 8 and DOT 8L cylinders. After both a technical and 
policy review of the petition, PHMSA agrees with Norris Cylinder there 
is no safety reason to require marking the service pressure on DOT 8 
and DOT 8L cylinders. In the NPRM, PHMSA proposed to revise this 
section as requested by the petitioner.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from Norris Cylinder and COSTHA. Both commenters noted a 
typographical error in the proposed language in Sec.  178.35(f)(7) 
specifying ``DOT 4 or 4AL cylinders,'' which should actually read ``DOT 
8 and 8AL cylinders.'' This correction aligns with the original 
petition, as well as the preamble text in the NPRM. Therefore, PHMSA is 
revising Sec.  178.35(f)(7) to no longer require DOT 8 and 8AL 
cylinders to be marked with the service pressure.
16. Incorporation of CGA Publication
    In petition P-1657, CGA proposed IBR updates to the CGA publication 
``CGA C-7-2014, Guide to Classification and Labeling of Compressed 
Gases, Tenth Edition'' currently listed in Sec.  171.7(n)(7). This 
publication has been updated to meet requirements for the U.S. 
Occupational Safety and Health Administration (OSHA) and was previously 
incorporated into OSHA's regulations in 2012. CGA requested that PHMSA 
permit the use of the 2014 edition of CGA C-7 to keep current with 
industry practices that are incorporated into Appendix A of C-7.
    PHMSA's review of the petition found that there are some editorial 
changes to the text of Appendix A in the 2014 edition that were added 
for clarity but do not impact the use of the required labels. In the 
NPRM, PHMSA proposed the incorporation by reference of ``CGA C-7-2014, 
Guide to Classification and Labeling of Compressed Gases, Tenth 
Edition'' into the HMR.
    PHMSA received no comments either supporting or opposing this 
proposal. Therefore, PHMSA is incorporating by reference ``CGA C-7-
2014, Guide to Classification and Labeling of Compressed Gases, Tenth 
Edition'' as proposed.
17. Use of Electronic Manifest
    In petition P-1659, COSTHA proposed to revise Sec.  172.205 to 
permit the use of electronic signatures when completing an EPA form 
8700-22 and 8700-22A. PHMSA reviewed and concurred with this proposed 
change, believing there is likely merit without a reduction in safety. 
In the NPRM, PHMSA proposed to add paragraph (j) to permit the use of 
electronic signatures when completing an EPA form 8700-22 and 8700-22A.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from HDA, AAR, COSTHA, DGAC, and Clifford Bartley. All 
commenters expressed support for the proposal. Additionally, AAR noted 
that ``it should be recognized that an electronic copy of the manifest 
can be used to meet the three-year retention requirement.'' Therefore, 
PHMSA is revising Sec.  172.205 to permit the use of electronic 
signatures when completing an EPA form 8700-22 and 8700-22A and 
recognizing that the electronic manifest can be used to meet the 3-year 
retention requirement.
18. Marked Date of Manufacture on Composite IBCs
    In petition P-1662, Rigid Intermediate Bulk Container Association 
of North America (RIBCA) proposed to amend Sec.  178.703(b) to 
acknowledge that the marked date of manufacture on a composite IBC may 
differ from the marked date of manufacture on the inner receptacle of 
that IBC. RIBCA petitioned PHMSA to propose the substance of the UN 
adopted note, ``The date of manufacture of the inner receptacle may be 
different from the marked date of manufacture (see 6.5.2.1), repair 
(see 6.5.4.5.3) or remanufacture (see 6.5.2.4) of the composite IBC,'' 
as a final sentence in Sec.  178.703(b)(6)(i) to read as follows: ``The 
date of manufacture of the inner receptacle may be different from the 
marked date of manufacture required by Sec.  178.703(a)(1)(iv) or by 
Sec.  180.352(d)(1)(iv).''
    Upon review of the petition, PHMSA found that allowing the inner 
receptacle and the composite IBC to have different date markings will 
have no effect on the safety of the use and manufacture of IBCs. 
Integrating the proposed language into the current HMR will also bring 
rules for the marking of dates of manufacture on IBCs in line with 
current international standards. In the NPRM, PHMSA proposed to revise 
the HMR to allow the date of manufacture on the inner receptacle to be 
different than on the composite IBC.
    In response to the proposed changes in the NPRM, PHMSA received a 
comment from RIBCA. RIBCA noted that this change will have no effect on 
safety when inner receptacles and composite IBCs are stamped with 
different dates reflecting manufacture or repair of a completed IBC. 
However, RIBCA disagreed with the language in the NPRM that states 
``provided that the retest and inspection of the IBCs be based on the 
earliest marked date.'' RIBCA contested that this language should be 
deleted because it is unnecessary from a safety perspective since inner 
packagings are sometimes built and stored well before being installed 
in composite IBCs. Therefore, as proposed, the retest and inspection 
would apply to an IBC well before an inner package becomes subject to 
detrimental effects, which begins when it is installed in the IBC. 
RIBCA noted that this language is inconsistent with other requirements 
in the regulations and more restrictive than the UN Model Regulations/
International Regulations, further noting that it would create an 
additional complexity for an IBC user because they will need to compare 
two different dates when determining required periodic tests and 
inspection dates.
    In response to these comment, PHMSA agrees to remove the language 
stating ``provided that the retest and inspection of IBCs be based on 
the earliest marked date.'' While PHMSA believes that including 
multiple dates may make it confusing to users and may make it difficult 
to know which to use, the marked date of repair is ultimately the date 
that must be used to determine the next inspection date. Also, because 
the repair phase of an IBC includes a leakproofness test, the 2.5-year 
time period should start from that point. However, comments from 
members of industry suggest that they are typically replaced in a 
timeframe less than 2.5 years, so this should not make a difference. 
Therefore, PHMSA is revising the changes to Sec.  178.703(b) to remove 
the above language.
19. Basis Weight Tolerances for Liners and Mediums Used in the 
Manufacture of Specification UN 4G Fiberboard Boxes
    In petition P-1663, COSTHA requested PHMSA revise the basis weight 
tolerance provided in

[[Page 55800]]

Sec.  178.516(b)(7) from +/- 5 percent to +/- 10 percent from the 
nominal basis weight reported in the initial design qualification test 
report.
    PHMSA conducted a review of the petition and found that the 
requested change is unlikely to affect safety and is largely following 
industry practices. The realities of paper manufacturing are such that 
a wide range of basis weights can be found on any large enough sample 
of fiberboard run on the same line to the same specification. This 
revision would only modify the percentage threshold for the allowable 
nominal basis weight for fiberboard boxes and would not result in any 
fundamental changes to testing, recordkeeping, or approval processes by 
either PHMSA or the regulated community. In the NPRM, PHMSA proposed to 
revise the basis weight tolerance provided in Sec.  178.516(b)(7) from 
+/- 5 percent to +/- 10 percent from the nominal basis weight reported 
in the initial design qualification test report.
    In response to the proposed changes in the NPRM, PHMSA received 
comments from DGAC, Clifford Bartley, Fibre Box Association, and 
COSTHA. All commenters expressed support for the proposal. Therefore, 
PHMSA is incorporating the changes as proposed to revise the basis 
weight tolerance provided in Sec.  178.516(b)(7) from +/- 5 percent to 
+/- 10 percent from the nominal basis weight reported in the initial 
design qualification test report.

IV. Section-by-Section Review

    Below is a section-by-section description of the changes being 
adopted in this final rule.

A. Section 171.7

    Section 171.7 lists all standards incorporated by reference into 
the HMR that are not specifically set forth in the regulations. This 
final rule incorporates by reference publications by the Chlorine 
Institute, the DoD, and the CGA.

Gas Cylinder Valves, Seventh Edition. This publication specifies 
general cylinder valve design, design qualification, required markings, 
and performance requirements such as operating temperature limits, 
pressure ranges, operating torque limits, and flow capabilities. It 
also provides testing and maintenance requirements.

B. Section 172.205

    Section 172.205 describes the requirements for the use of hazardous 
waste manifest. This final rule revises paragraph (j) to permit the use 
of electronic signatures when completing an EPA form 8700-22 and 8700-
22A.

C. Section 172.407

    Section 172.407 describes the label specifications for packages 
shipping hazardous materials under the HMR. This final rule revises 
paragraph (c) to allow for size tolerances for the labels by inserting 
the term ``approximately'' for the inner border to be 5 mm. This final 
rule also revises paragraph (f) to address inconsistencies between 
international and domestic labels.

D. Section 172.519

    Section 172.519 describes placard specification for shipments of 
hazardous materials that require placards. This final rule revises 
paragraph (c) to allow for size tolerances for the placards by 
inserting the term ``approximately'' for the inner border to be 5 mm. 
This final rule also revises paragraph (f) to address inconsistencies 
between international and domestic placards.

E. Section 172.604

    Section 172.604 describes the requirements to have an emergency 
response number on shipping papers for shipments of hazardous 
materials. This final rule revises Sec.  172.604(d) to no longer 
require an emergency response number for excepted quantities of 
hazardous materials.

F. Section 173.5a

    Section 173.5a outlines the requirements for cargo tank motor 
vehicles used for roadway striping. This final rule adds proper 
shipping names in Sec.  173.5a(c)(1) to the list of authorized 
materials that can be used under this section.

G. Section 173.24a

    Section 173.24a outlines the general requirements for non-bulk 
packages. This final rule revises each paragraph in this section to 
allow for packages tested with a liquid material to be filled with a 
solid material of the equivalent packing group.

H. Section 173.31

    Section 173.31 outlines the specifications for the use of tank 
cars. Specifically, Sec.  173.31(e) outlines the specifications for 
tank cars used to transport materials that are poisonous by inhalation. 
This final rule removes the reference to the 20-year service life for 
these tank cars in Sec.  173.31(e)(2)(iii), thus extending the service 
life to the standard for all tank cars set forth at Sec.  215.203 of 
the FRA regulations.

I. Section 173.150

    Section 173.150 outlines exceptions for Class 3 flammable and 
combustible liquids. This final rule changes the units in Sec.  
173.150(g) from imperial units to the International System of Units and 
revises all the units in this section to the International System of 
Units.

J. Section 173.156

    Section 173.156 outlines exceptions for limited quantities and ORM-
D materials. This final rule revises Sec.  173.156(b)(2)(iii) to allow 
for pallets to be made of metal, plastic, or composite materials in 
addition to wood.

K. Section 173.301

    Section 173.301 outlines the general requirements for the shipment 
of compressed gases and other hazardous materials in cylinders, UN 
pressure receptacles, and spherical pressure vessels. This final rule 
revises Sec.  173.301(a) by adding subparagraphs (11) and (12). 
Paragraph (11) will require all cylinder valves manufactured on or 
after May 4, 2015, to conform to the requirements in CGA V-9-2012, as 
well as requiring UN pressure receptacles to conform to the 
requirements of Sec.  173.301b(c)(1). Paragraph (12) will require that 
cylinder valve protection caps manufactured on or after May 4, 2015, 
conform to the requirements of CGA V-9-2012. Cylinder valve protection 
caps used on UN cylinders must conform to the requirements in Sec.  
173.301b(c)(2)(ii).

L. Section 173.335

    Section 173.335 outlines the requirements for chemicals under 
pressure, n.o.s. This final rule revises Sec.  173.335(a) to clarify 
that these materials are not subject to the cylinder valve requirements 
finalized in Sec.  173.301(a)(11).

M. Section 176.415

    Section 176.415 outlines permit requirements for Division 1.5, 
ammonium nitrates, as well as certain ammonium nitrate fertilizers. 
This final rule revises the HMR to no longer require written permission 
from the COTP to load or unload limited quantities of ammonium 
nitrates.

N. Section 178.35

    Section 178.35 outlines the general requirements for specification 
cylinders. This final rule revises Sec.  178.35 to no longer require 
the marking of the service pressure for DOT 8 and DOT 8 AL cylinders.

O. Section 178.337

    Section 178.337-9 outlines the requirements for pressure relief 
devices, piping, valves, hoses, and fittings. This final rule revises 
Sec.  178.337-9(b)(8) to add a reference to allow the use of ``Sections 
4 through 6, Pamphlet 168, Guidelines for Dual Valve Systems for Bulk 
Chlorine Transport, Edition 2, July 2015'' under this section.

P. Section 178.516

    Section 178.516 outlines the standards for fiberboard boxes. This 
final rule revises Sec.  178.516(b)(7) to allow for the paper wall 
basis weights that vary by not more than +/- 10 percent from the 
nominal basis weight reported in the initial design qualification test 
report.

Q. Section 178.703

    Section 178.703 outlines the marking requirements for IBCs. This 
final rule revises Sec.  178.703(b)(6)(i) by clarifying that the date 
of manufacture of the inner receptacle may be different from the marked 
date of manufacturer required by Sec.  178.703(a)(1)(iv) or Sec.  
180.352(d)(1)(iv).

R. Section 180.407

    Section 180.407 outlines the requirements for the testing and 
inspection of specification cargo tanks. This final rule revises the 
table in Sec.  180.407(g)(1)(iv) to put the words ``The test pressure 
on the name plate or specification plate, or 1.5 times the MAWP, 
whichever is greater'' in the test pressure column before each test 
pressure specification.

S. Section 180.605

    Section 180.605 outlines the requirements for periodic testing, 
inspection, and repair of portable tanks. This final rule revises Sec.  
180.605(l) by adding Sec.  180.605(l)(2) to allow the owner of a 
portable tank to contact the National Board for a copy of the 
manufacture's data report, if the portable tank was registered with the 
National Board, or copy the information contained on the portable 
tank's specification plate and ASME Code data plates.

V. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This final rule is published under authority of the Federal 
Hazardous Materials Transportation Law (Federal Hazmat Law; 49 U.S.C. 
5101 et seq.). Section 5103(b) of 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 delegated 
her authority to PHMSA at 49 CFR 1.97.

B. Executive Order 12866, Executive Order 13563, Executive Order 13610, 
Executive Order 13771, and DOT Regulatory Policies and Procedures

    This final rule is not considered a significant regulatory action 
under section 3(f) of Executive Order 12866, ``Regulatory Planning and 
Review'' (58 FR 51735; Oct. 4, 1993), and was not reviewed by the 
Office of Management and Budget (OMB). This final rule is also not 
considered a significant rule under the Regulatory Policies and 
Procedures order issued by the U.S. Department of Transportation on 
February 26, 1979. See 44 FR 11034.
Background
    PHMSA has involved the public in the regulatory process in a 
variety of ways for this final rule. Specifically, in this rulemaking 
PHMSA is responding to 19 petitions that have been submitted by the 
public in accordance with the APA and PHMSA's rulemaking procedure 
regulations (49 CFR 106.95).
    Overall, this rulemaking maintains the continued safe 
transportation of hazardous materials while producing a net cost 
savings. PHMSA's findings are summarized here and described in further 
detail in the Regulatory Impact Analysis (RIA), which can be found in 
the regulatory docket (Docket ID: PHMSA-2015-0102) at 
www.regulations.gov.
Summary of Findings
    PHMSA estimates a present value of quantified net cost savings of 
approximately $237 million over 10 years and $16.5 million annualized 
at a 7 percent discount rate. 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 five petitions included in this final rule. Three of the 
petitions that were monetized contained cost savings, while two 
petitions have minor costs. One provision in particular is responsible 
for the vast majority of the cost savings estimated: The extension of 
the regulatory life of HM-246-compliant PIH tank cars from 20 years to 
50 years, as allowed by FRA regulation, see 49 CFR 215.203, for other 
tank cars in its class. This regulatory life extension is expected to 
reduce PIH tank car replacement costs that would occur in the absence 
of rulemaking. Moreover, these tank cars are more robust and less 
likely to release material than legacy PIH tank cars, resulting in 
safety benefits such as reduced incident damages. The following table 
presents a summary of the five petitions that have monetized impacts 
upon codification and contribute to PHMSA's estimation of quantified 
net cost savings.

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

    In addition to these five items, PHMSA described an additional 14 
items that are deregulatory in nature but lack of monetization of their 
cost savings impacts. While information gaps prevent quantification of 
cost savings for these items, PHMSA believes that they relax current 
requirements or provide additional flexibility, and therefore should be 
considered deregulatory in nature.
Conclusion
    In conclusion, PHMSA estimates a present value of quantified net 
cost savings of approximately $237 million over a perpetual time 
horizon and $16.5 million annualized at a 7 percent discount rate. 
Please see the RIA in the regulatory docket for additional detail and a 
description of PHMSA's methods and calculations.

C. Executive Order 13132

    This final rule was analyzed in accordance with the principles and 
criteria contained in Executive Order 13132, ``Federalism'' (64 FR 
43255; Aug. 10, 1999). This final rule would preempt State, local, and 
Indian tribe requirements but does not impose any regulation that has 
substantial direct effects on the States, the relationship between the 
national government and the States, or the distribution of power and 
responsibilities among the various levels of government. Therefore, the 
consultation and funding requirements of Executive Order 13132 do not 
apply.
    Federal Hazmat Law, 49 U.S.C. 5125(b)(1), contains an express 
preemption provision (49 U.S.C. 5125(b)) preempting State, local, and 
Indian tribe requirements on certain covered subjects. Covered subjects 
are:
    (i) The designation, description, and classification of hazardous 
materials;
    (ii) The packing, repacking, handling, labeling, marking, and 
placarding of hazardous materials;
    (iii) The preparation, execution, and use of shipping documents 
related to hazardous materials and requirements related to the number, 
content, and placement of those documents;
    (iv) The written notification, recording, and reporting of the 
unintentional release in transportation of hazardous materials; or
    (v) The design, manufacture, fabrication, marking, maintenance, 
reconditioning, repair, or testing of a packaging or container which is 
represented, marked, certified, or sold as qualified for use in the 
transport of hazardous materials.

[[Page 55803]]

    This final rule concerns the classification, packaging, marking, 
labeling, and handling of hazardous materials, among other covered 
subjects. This rule would preempt any State, local, or Indian tribe 
requirements concerning these subjects unless the non-Federal 
requirements are ``substantively the same'' as the Federal 
requirements. See 49 CFR 107.202(d).
    Federal Hazmat Law provides at 49 U.S.C. 5125(b)(2) that if PHMSA 
issues a regulation concerning any of the covered subjects, the 
administration must determine and publish in the Federal Register the 
effective date of Federal preemption. That effective date may not be 
earlier than the 90th day following the date of issuance of the final 
rule and not later than 2 years after the date of issuance. PHMSA 
proposes the effective date of Federal preemption be 90 days from 
publication of a final rule in this matter in the Federal Register.

D. Executive Order 13175

    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 13175, ``Consultation and 
Coordination with Indian Tribal Governments'' (65 FR 67249; Nov. 9, 
2000). Because this final rule does not have Tribal implications and 
does not impose substantial direct compliance costs on Indian tribal 
governments, the funding and consultation requirements of Executive 
Order 13175 do not apply, and a Tribal summary impact statement is not 
required.

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

    The Regulatory Flexibility Act, 5 U.S.C. 601 requires an agency to 
review regulations to assess their impact on small entities unless the 
agency determines the rule is not expected to have a significant impact 
on a substantial number of small entities. This final rule amends 
miscellaneous provisions in the HMR for clarification based on 
petitions for rulemaking. While maintaining safety, this final rule 
would relax certain requirements that are overly burdensome and provide 
clarity where requested by the regulated community. The changes are 
generally intended to provide relief to shippers, carriers, and 
packaging manufacturers, including small entities.
    The Regulatory Flexibility Act directs agencies to establish 
exceptions and differing compliance standards for small businesses, 
where it is possible to do so and still meet the objectives of 
applicable regulatory statutes. In the case of hazardous materials 
transportation, it is not possible to establish exceptions or differing 
standards and still accomplish our safety objectives.
    The changes are generally intended to provide relief to shippers, 
carriers, and packaging manufactures and testers, including small 
entities. Therefore, PHMSA certifies that this final rule will not have 
a significant economic impact on a substantial number of small 
entities.
    This final rule has been developed in accordance with Executive 
Order 13272, ``Proper Consideration of Small Entities in Agency 
Rulemaking'' (67 FR 53461; Aug. 16, 2002) and DOT's Policies and 
Procedures to promote compliance with the Regulatory Flexibility Act to 
ensure that potential impacts of draft rules on small entities are 
properly considered.

F. Paperwork Reduction Act

    This final rule does not impose any new information collection 
requirements and, in one instance, marginally decreases the information 
collection burden on the regulated community. Specifically, the 
following information collection requirement is affected by this 
rulemaking:
    OMB Control No. 2137-0034: Hazardous Materials Shipping Papers and 
Emergency Response Information.
    Decrease in Annual Number of Respondents: 1,000.
    Decrease in Annual Responses: 1,666,667.
    Decrease in Annual Burden Hours: 4,629.
    Decrease in Annual Burden Cost: $95,403.69.
    PHMSA estimates that no longer requiring the emergency response 
number for limited quantity shipments by vessel will reduce the number 
of burden hours by 4,629. PHMSA estimates that no longer requiring the 
emergency response number on shipping paper will save 10 seconds per 
shipping paper and affect 1,666,667 shipments per year. PHMSA estimates 
a savings of $.06 per shipment resulting in cost savings of $95,403.69.
    Please direct your requests for a copy of this final information 
collection to Steven Andrews or T. Glenn Foster, Office of Hazardous 
Materials Standards (PHH-12), Pipeline and Hazardous Materials Safety 
Administration, 1200 New Jersey Avenue SE, 2nd Floor, Washington, DC 
20590-0001.

G. Regulation Identifier Number (RIN)

    A regulation identifier number (RIN) is assigned to each regulatory 
action listed in the Unified Agenda of Federal Regulations. The 
Regulatory Information Service Center publishes the Unified Agenda in 
spring and fall of each year. The RIN number contained in the heading 
of this document can be used to cross-reference this action with the 
Unified Agenda.

H. Unfunded Mandates Reform Act

    This final rule does not impose unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. Public Law 104-4 (Mar. 22, 1995). 
It does not result in costs in any one year of $141.3 million or more 
to either State, local, or Tribal governments, in the aggregate, or to 
the private sector, and is the least burdensome alternative that 
achieves the objective of the rule.

I. Environmental Assessment

    The National Environmental Policy Act, 42 U.S.C. 4321-4375, 
requires Federal agencies to analyze proposed actions to determine 
whether the action will have a significant impact on the human 
environment. The Council on Environmental Quality (CEQ) regulations 
require Federal agencies to conduct an environmental review 
considering: (1) The need for the proposed action; (2) alternatives to 
the proposed action; (3) probable environmental impacts of the proposed 
action and alternatives; and (4) the agencies and persons consulted 
during the consideration process.
Need for the Proposed Action
    In response to petitions for rulemaking submitted by the regulated 
community, PHMSA is amending the HMR to update, clarify, or provide 
relief from miscellaneous regulatory requirements. In this final rule, 
PHMSA is implementing amendments that include, but are not limited to, 
the following: Incorporating by Reference multiple publications from 
the CGA, the Chlorine Institute, and DoD; addressing inconsistencies 
with domestic and international labels and placards; excepting excepted 
quantities from the emergency response telephone requirement; allowing 
electronic signatures for EPA manifest forms; and no longer requiring 
the service pressure to be marked on DOT 8 and 8AL cylinders.
    These amendments are intended to promote safety, regulatory relief, 
and clarity. The proposed changes were identified in response to 
petitions from stakeholders affected by the HMR. These minor changes 
will clarify the HMR and enhance safety, while offering some net 
economic benefits.
    This action is necessary to: (1) Fulfill our statutory directive to 
promote transportation safety; (2) fulfill our

[[Page 55804]]

statutory directive under the Administrative Procedure Act (APA) that 
requires Federal agencies to give interested persons the right to 
petition an agency to issue, amend, or repeal a rule (5 U.S.C. 553(e)); 
(3) support governmental efforts to provide regulatory relief to the 
regulated community; (4) address safety concerns raised by petitioners 
and remove identified regulatory ambiguity; and (5) simplify and 
clarify the regulations in order to promote understanding and 
compliance.
    The intended effect of this action is to enhance the safe 
transportation of hazardous materials and, in conjunction, clarify, 
simplify, and relax certain regulatory requirements for carriers, 
shippers, and other stakeholders. These regulatory revisions will offer 
more efficient and effective ways of achieving PHMSA's goal of safe and 
secure transportation, protecting both people and the environment, of 
hazardous materials in commerce.
Alternatives
    In developing the final rule, PHMSA considered the following 
alternatives:
Alternative 1: No Action
    If PHMSA chose this alternative, we would not proceed with any 
rulemaking on this subject and the current regulatory standards would 
remain in effect. This option would not address outstanding petitions 
for rulemaking. We rejected the No Action Alternative.
Alternative 2: Go Forward With the Proposed Amendments to the HMR in 
This NPRM
    This alternative is the current proposal as it appears in this 
final rule, applying to transport of hazardous materials by highway, 
rail, vessel, and aircraft. The amendments encompassed in this 
alternative are more fully addressed in the preamble and regulatory 
text sections of this rulemaking.
Probable Environmental Impacts of the Alternatives
    When developing potential regulatory requirements, PHMSA considers 
the environmental impact of each amendment. Specifically, PHMSA 
evaluates the: Risk of release and resulting environmental impact; risk 
to human safety, including any risk to first responders; longevity of 
the packaging; and if the proposed regulation would be carried out in a 
defined geographic area, the resources, especially any sensitive areas, 
and how they could be impacted by any proposed regulations. Of the 
regulatory changes proposed in this rulemaking, most have been 
determined to be clarification, technology/design updates, 
harmonization, regulatory flexibility, standard incorporation, or 
editorial in nature. As such, these amendments have little or no impact 
on the risk of release and resulting environmental impact; human 
safety; or longevity of the packaging. None of these amendments would 
be carried out in a defined geographic area (i.e., this is a nationwide 
rulemaking).
Alternative 1: No Action
    If PHMSA were to select the No Action Alternative, current 
regulations would remain in place and no new provisions would be added. 
However, efficiencies gained through harmonization in updates to 
transport standards, lists of regulated substances, definitions, 
packagings, markings requirements, shipper requirements, modal 
requirements, etc., would not be realized. Foregone efficiencies in the 
No Action Alternative also include freeing up limited resources to 
concentrate on hazardous materials transportation issues of potentially 
much greater environmental impact. Not adopting the proposed 
environmental and safety requirements under the No Action Alternative 
would result in a lost opportunity for reducing negative environmental 
and safety-related impacts. Greenhouse gas emissions would remain the 
same under the No Action Alternative.
Alternative 2: Go forward With the Proposed Amendments to the HMR in 
This NPRM
    This Preferred Alternative encompasses enhanced and clarified 
regulatory requirements, which would result in increased compliance and 
fewer negative environmental and safety impacts. The table below 
summarizes possible environmental benefits and any potential negative 
impacts for the amendments in this final rule. A detailed discussion on 
the potential environmental impacts of each type of amendment is 
included in the complete Environmental Assessment placed in the docket 
for this rulemaking.

Preferred Alternative
    PHMSA has selected the Preferred Alternative. As discussed in the 
table above, we expect no or very slight positive environmental impacts 
from the Preferred Alternative.
Agencies Consulted
    This final rule would affect some PHMSA stakeholders, including 
hazardous materials shippers and carriers by highway, rail, vessel, and 
aircraft, as well as package manufacturers and testers. PHMSA sought 
comment on the Environmental Assessment contained in the June 30, 2016, 
NPRM published under Docket No. PHMSA 2015-0102 [81 FR 42609] (HM-
219A); however, PHMSA did not receive any comments. In addition, PHMSA 
sought comment from the following Federal agencies and modal partners:

 Department of Defense
 Environmental Protection Agency
 Federal Aviation Administration
 Federal Motor Carrier Safety Administration
 Federal Railroad Administration
 United States Coast Guard (USCG)

    These Federal agencies did not submit to PHMSA any adverse comments 
on the amendments proposed in the NPRM.
Conclusion
    The revisions in this final rule are intended to update, clarify, 
or provide relief from certain existing regulatory requirements to 
promote safer transportation practices; eliminate unnecessary 
regulatory requirements; facilitate international commerce; and make 
these requirements easier to understand. These amendments will foster a 
greater level of compliance with the HMR, and thus the net 
environmental impact of this proposal will be slightly positive.
    The provisions of this final rule build on current regulatory 
requirements to enhance the transportation safety and security of 
shipments of hazardous materials transported by highway, rail, 
aircraft, and vessel, thereby reducing the risks of an accidental or 
intentional release of hazardous materials and consequent environmental 
damage. PHMSA believes that there are no non-negligible environmental 
impacts associated with this final rule.

J. Privacy Act

    Anyone is able to search the electronic form of any written 
communications and comments received into any of our dockets by the 
name of the individual submitting the document (or signing the 
document, if submitted on behalf of an association, business, labor 
union, etc.). DOT posts these comments, without edit, including any 
personal information the commenter provides, to www.regulations.gov, as 
described in the system of records notice (DOT/ALL-14 FDMS), which can 
be reviewed at www.dot.gov/privacy.

K. Executive Order 13609 and International Trade Analysis

    Under Executive Order 13609, ``Promoting International Regulatory 
Cooperation'' (77 FR 26413; May 4, 2012), agencies must consider 
whether the impacts associated with significant variations between 
domestic and international regulatory approaches are unnecessary or may 
impair the ability of American business to export and compete 
internationally. In meeting shared challenges involving health, safety, 
labor, security, environmental, and other issues, international 
regulatory cooperation can identify approaches that are at least as 
protective as those that are or would be adopted in the absence of such 
cooperation. International regulatory cooperation can also reduce, 
eliminate, or prevent unnecessary differences in regulatory 
requirements.
    Similarly, the Trade Agreements Act of 1979 (Pub. L. 96-39), as 
amended by the Uruguay Round Agreements Act (Pub. L. 103-465), 
prohibits Federal agencies from establishing any standards or engaging 
in related activities that create unnecessary obstacles to the foreign 
commerce of the United States. For purposes of these requirements, 
Federal agencies may participate in the establishment of international 
standards, so long as the standards have a legitimate domestic 
objective, such as providing for safety, and do not operate to exclude 
imports that meet this objective. The statute also requires 
consideration of international standards and, where appropriate, that 
they be the basis for U.S. standards.
    PHMSA participates in the establishment of international standards 
in order to protect the safety of the American public, and we have 
assessed the effects of the final rule to ensure that it does not cause 
unnecessary obstacles to foreign trade. Accordingly, this rulemaking is 
consistent with Executive Order 13609 and PHMSA's obligations under the 
Trade Agreement Act, as amended.

L. National Technology Transfer and Advancement Act

    The National Technology Transfer and Advancement Act of 1995 (15 
U.S.C. 272 note) directs Federal agencies to use voluntary consensus 
standards in their regulatory activities unless doing so would be 
inconsistent with applicable law or otherwise impractical. Voluntary 
consensus standards are technical standards (e.g., specification of 
materials, test methods, or performance requirements) that are 
developed or adopted by voluntary consensus standard bodies. This final 
rule involves multiple voluntary consensus standards which are 
discussed at length in the ``Section-by-Section Review'' for Sec.  
171.7.

    (l) Record retention. (1) The owner of each portable tank or his 
authorized agent shall retain a written record of the date and results 
of all required inspections and tests, including an ASME manufacturer's 
date report, if applicable, and the name and address of the person 
performing the inspection or test, in accordance with the applicable 
specification. The manufacturer's data report, including a 
certificate(s) signed by the manufacturer, and the authorized design 
approval agency, as applicable, indicating compliance with the 
applicable specification of the portable tank, and related papers 
certifying that the portable tank was manufactured and tested in 
accordance with the applicable specification must be retained in the 
files of the owner, or his authorized agent, during the time that such 
portable tank is used for such service, except for Specifications 56 
and 57 portable tanks.
    (2) If the owner does not have the manufacturer's certificate 
required by the specification and the manufacturer's data report 
required by the ASME, the owner may contact the National Board for a 
copy of the manufacturer's data report, if the portable tank was 
registered with the National Board, or copy the information contained 
on the portable tanks specification plate and ASME Code data plates.
