Hazardous Materials: Adoption of Special Permits (MAP-21) (RRR)

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA), 
DOT.

ACTION: Final rule.

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

SUMMARY: As required by the Moving Ahead for Progress in the 21st 
Century Act
    (MAP-21), the Pipeline and Hazardous Materials Safety 
Administration is amending the Hazardous Materials Regulations to adopt 
provisions contained in certain widely-used or long-standing special 
permits that have an established safety record. The adopted amendments 
are intended to provide wider access to the regulatory flexibility 
offered in special permits and eliminate the need for numerous renewal 
requests. The adopted amendments will also reduce paperwork burdens and 
facilitate commerce while maintaining an appropriate level of safety. 
PHMSA conducted an extensive analysis of all active special permits and 
codified, as appropriate, those special permits deemed suitable in this 
rulemaking.

DATES: Effective Date: The final rule will become effective on February 
22, 2016.
    Voluntary compliance date: PHMSA is authorizing voluntary 
compliance beginning February 22, 2016.
    Delayed compliance date: Unless otherwise specified, compliance 
with the amendments adopted in this final rule is required beginning 
January 23, 2017.

I. Executive Summary

    The Pipeline and Hazardous Materials Safety Administration (PHMSA) 
is amending the Hazardous Materials Regulations (HMR; 49 CFR parts 171-
180) by adopting requirements contained in 96 existing special permits 
(SP). These amendments are based on our review of all active SPs as of 
January 1, 2013, in which we originally identified 98 SPs containing 
requirements that appear suitable for adoption into the HMR as 
regulations of general applicability. Other SPs (1,070) were not 
proposed for adoption into the HMR because we concluded they contain 
requirements which (1) would not have, or are being applied in a manner 
which would not have, broad applicability; or (2) have already been 
adopted into the HMR, are covered by authorizations in the HMR, are 
being addressed in other rulemakings, or were removed from 
consideration after receiving public comments submitted in response to 
the January 30, 2015, notice of proposed rulemaking (NPRM) in this 
proceeding.
    In the NPRM published in the Federal Register on January 30, 2015 
[80 FR 5339], we encouraged all interested parties, particularly the 
holders of currently active SPs, to submit comments regarding the SPs 
we proposed to adopt into the HMR, the SPs we did not propose to adopt 
into the HMR, and the impacts, including costs and benefits, of the 
special permits proposed for incorporation.

II. Background

    PHMSA is amending the Hazardous Materials Regulations (HMR; 49 CFR 
Parts 171-180) by adopting certain requirements based on existing SPs 
issued by PHMSA under 49 CFR part 107, subpart B (Sec. Sec.  107.101 to 
107.127). SPs set forth alternative requirements--or a variance--to the 
requirements in the HMR in a way that achieves a safety level at least 
equal to the safety level required under the regulations, or, when the 
regulations do not establish a safety level, that is consistent with 
the public interest. Congress expressly authorized the Secretary of 
Transportation to issue these variances in the Hazardous Materials 
Transportation Act of 1975 (49 U.S.C. 5109) as amended.
    On July 6, 2013, President Obama signed legislation entitled 
``Moving Ahead for Progress in the 21st Century Act (MAP-21).'' Section 
33012 of this legislation required PHMSA to review and analyze SPs that 
have been in continuous effect for a 10-year period to determine which 
ones may be codified into the HMR.\1\ The legislation also required 
PHMSA to issue regulations to adopt any SPs identified as appropriate 
for adoption in a final rule by October 1, 2015. The legislation 
provided the following factors to consider during review and analysis 
to determine suitability for adoption into the HMR:
---------------------------------------------------------------------------

    \1\ Although MAP-21 only required PHMSA evaluate SPs that had 
been in continuous effect for a 10-year period, PHMSA reviewed all 
active SPs as of January 1, 2013.
---------------------------------------------------------------------------

    (1) The safety record of the hazardous materials (hazmat) 
transported under the SP;
    (2) The application of a SP;
    (3) The suitability of the provisions in the SP for incorporation 
into the hazmat regulations; and
    (4) Rulemaking activity in related areas.
    Prior to the passing of the MAP-21 legislation, PHMSA completed 
numerous rulemaking actions, through a comprehensive and refined 
approach, to convert long-standing SPs with an established safety 
record into the HMR.

[[Page 3637]]

Following the passage of the MAP-21 legislation, PHMSA modified its 
approach to align with the requirements of this legislation. 
Specifically, PHMSA established terms of reference and baseline 
criteria for the review of long-standing SPs, created tracking tools to 
monitor progress, and adopted a methodology and timeline to evaluate 
SPs.
    The January 30, 2015 NPRM provided an overview of the SP Program to 
date, a detailed review of the requirements of MAP-21 with regard to 
this initiative, and a comprehensive explanation of the rationale used 
to evaluate these SPs both prior to and after the implementation of 
MAP-21. Furthermore, the NPRM described in detail the SPs that were 
deemed not suitable for adoption into the HMR along with the 
corresponding reasoning, and proposed the adoption into the HMR of SPs 
that were deemed suitable through this review. The amendments adopted 
from the SPs in this final rule have broad applicability, fit into the 
scope of the HMR, increase flexibility in transportation, and provide 
an equivalent level of safety to that of the current regulations.

III. Overview

    Historically, PHMSA has reviewed widely used or long-standing 
special permits and adopted those that have an established safety 
record into the HMR. Since 2008, PHMSA has adopted 94 special permits 
under various rulemakings into the HMR, reducing the number of holders 
by 13,947. Rulemakings that stemmed from a special permit are noted in 
Table 1.

A. MAP-21 Legislation

    Section 33012 of the MAP-21 legislation revised section 5117 (f) of 
the Federal Hazardous Materials Transportation Law. As a result of this 
legislation, PHMSA was required to review and analyze SPs that have 
been in effect for 10 years or more and determine which could be 
converted into regulations. Additionally, PHMSA was required to set 
parameters for the review and issue regulations to adopt any SPs 
identified as appropriate for adoption in a final rule by October 1, 
2015. Following publication of this final rule, this process would be 
completed annually to ensure appropriate SPs are converted into the HMR 
on a consistent basis.
    The legislation also required PHMSA to address other issues related 
to the SP and approvals regulations and program processes. 
Specifically, PHMSA is required to issue regulations on standard 
operating procedures to support administration of the SP and approval 
programs. This requirement is being addressed under Docket No. PHMSA 
2012-0260 (HM-233E).
    Table 2 summarizes the MAP-21 requirements related to the SP 
program, the corresponding rulemaking actions, and required completion 
dates:

B. SP Conversion Project Methodology

    As previously stated, PHMSA has routinely analyzed, evaluated, and 
adopted SPs into the HMR through established procedures for decades. 
However, the specific provisions contained in MAP-21 necessitated PHMSA 
to modify and formalize its approach.
    The following table summarizes the different phases of the Special 
Permits Conversion Project (SPCP). Specifically, this table briefly 
discusses the efforts of each phase of the project and how the entire 
project was divided into the two primary stages of analysis and 
rulemaking. Each phase of the SPCP is described in Table 3.

                        Table 3--SPCP Methodology
------------------------------------------------------------------------
               Phase                        Description of action
------------------------------------------------------------------------
Analysis:
    Phase 1: Development of         The SPCP Management team developed a
     Methodology.                    methodology to consistently
                                     evaluate SPs, a system to track
                                     this analysis, sub-teams and sub-
                                     topic areas used to group similar
                                     SPs to be reviewed by the
                                     appropriate subject matter experts,
                                     and timelines and milestones.
    Phase 2: Preliminary Analysis.  An initial review of all SPs was
                                     conducted. SPs were divided by
                                     topics and sub-topics and each
                                     transportation regulations
                                     specialist was assigned a grouping.
                                     These specialists reviewed each
                                     permit and made a determination as
                                     to an SP's suitability for adoption
                                     into the HMR based on guidance
                                     provided by the SPCP Management
                                     team.
    Phase 3: Mentor Review........  The members of the SPCP Management
                                     were assigned topics and conducted
                                     a second review of the SPs deemed
                                     either not suitable or flagged for
                                     further review.
    Phase 4: Team Analysis........  PHMSA then established rulemaking
                                     teams for each topic composed of a
                                     team leader, mentor, and team
                                     members from each PHMSA Division
                                     and our modal partners. These teams
                                     then conducted a second review of
                                     those SPs deemed suitable and those
                                     flagged for follow-up.
Rulemaking:
    Phase 5: Drafting.............  For SPs deemed suitable, the team
                                     drafted regulatory text along with
                                     preamble language justifying
                                     inclusion into the HMR. The
                                     finalized draft of each topic was
                                     then submitted to the SPCP
                                     Management team for final review.
    Phase 6: Consolidate            Following review by the SPCP
     Rulemaking.                     Management team, the topic
                                     rulemakings were then combined into
                                     a master draft along with
                                     additional preamble language,

    PHMSA grouped each special permit into one of six topic areas, 
based on the utility of the special permit. These topic areas were 
established to reflect the main utility and purpose of the SP. These 
topic areas of the SPs, an overview of each topic area, and the 
affected number of SP holders are detailed in Table 4.

C. Petitions for Rulemaking

    PHMSA considered several petitions for rulemaking submitted in 
accordance with Sec.  106.105. The petitions are discussed as follows:
---------------------------------------------------------------------------

    \3\ For the purposes of this rulemaking Non-Destructive Testing 
(NDT) includes Ultrasonic Examination (UE) and Acoustic Emission 
(AE).
---------------------------------------------------------------------------

P-1607
    The Council on the Safe Transportation of Hazardous Articles 
(COSTHA) submitted a petition for rulemaking under P-1607 which PHMSA 
accepted and proposed in the January 30, 2015 NPRM. The purpose of this 
petition for rulemaking was to adopt the provisions of SP 11458 
authorizing display packs of consumer commodities that exceed the 30 kg 
gross weight limitation prescribed for limited quantity packages. See 
the discussions in Sec. Sec.  171.8 and 173.56 under the ``Operational 
Highway/Rail/Shipper/Other'' heading of this rulemaking.
P-1608
    The Truck Trailer Manufacturers Association (TTMA) submitted a 
petition for rulemaking under P-1608 to adopt the provisions of SP 
11903 into the HMR. Under P-1608, TTMA petitioned that PHMSA adopt 
standards for the construction and use of fiber reinforced plastic 
(FRP) cargo tanks. Currently, these tanks are constructed under SP 
11903 and used under party status to SP 9166. Other special permits 
also address these standards but PHMSA did not propose to adopt them in 
the NPRM because a uniform standard for FRP cargo tanks that is ready 
for adoption does not exist. However, PHMSA is working to develop a 
uniform standard for FRP cargo tanks, which we will address in a future 
rulemaking.
P-1610
    COSTHA submitted a petition for rulemaking under P-1610 to adopt 
the provisions of SP 11110 into the HMR. This SP authorizes cargo 
aircraft operators to stow Division 1.4S and Class 8, PG III materials 
in inaccessible cargo locations in excess of the limitations specified 
in Sec.  175.75(c). This petition has been accepted by PHMSA for 
consideration in a future rulemaking as more time is needed to research 
the potential impact of changes to Sec.  175.75 and to coordinate this 
review with the appropriate parties, including our modal partners.
P-1611
    COSTHA submitted a petition for rulemaking under P-1611 to adopt 
the provisions of SP 11470 into the HMR. This SP authorizes the 
transportation in commerce of shrink-wrapped pallets containing 
packages of waste ORM-D materials with the word ``WASTE'' marked on the 
outside of the pallet instead of each individual box. This petition was 
accepted by PHMSA and is being adopted as proposed in this final rule. 
See the discussion in Sec.  173.12 under the ``Operational Highway/
Rail/Shipper/Other'' heading of this preamble.

D. SP Evaluation Results

    PHMSA is committed to the SP adoption process established by 
Congress in MAP-21. To ensure that changes made under this action are 
as efficient and effective as possible, PHMSA solicited input from its 
stakeholders. We used several tables throughout the NPRM to identify 
SPs suitable for adoption and those that were deemed not suitable. As 
required by MAP-21, the initial review and analysis of SPs considered 
the following factors:
     The safety record of hazardous materials transported under 
the SP;
     The application of a SP;
     The suitability of provisions in the SP for adoption into 
the HMR; and
     Rulemaking activity in related areas.
    Based on these factors, PHMSA developed and assigned codes 
representing its reasoning for adopting or not adopting certain SPs 
into the regulations. Table 5 explains each code.

Code 2...........  Not Suitable for       SPs not suitable because of
                    Adoption: The          the manner in which applied.
                    application of the     Because the purpose of the
                    SP.                    MAP-21 directive was to
                                           reduce need for SPs where
                                           widely-used, many of these
                                           SPs were not considered
                                           suitable for adoption because
                                           of their application; i.e.,
                                           they were not widely-used,
                                           were too technical in nature,
                                           or were too specific to a SP
                                           holder. This Code was applied
                                           to both single and multiple
                                           holders of SPs.
Code 3...........  Not Suitable for       SPs not suitable for adoption
                    Adoption: The          because of the lack of broad
                    suitability of the     applicability. Similar to
                    provision in the SP    Code 2, many of these SPs
                    for adoption into      were not considered suitable
                    the HMR.               for adoption because of the
                                           specificity of the SP. The
                                           terms of these SPs often
                                           included an inability to
                                           provide the same exception in
                                           a broad manner applicable to
                                           certain geographical
                                           locations or safety controls.
                                           This Code was also applied to
                                           both single and multiple
                                           holders of SPs.
Code 4...........  Not Suitable for       SPs being addressed in other
                    Adoption: Rulemaking   rulemakings.
                    activity in related
                    areas.
Code 5...........  Already adopted or     SPs already adopted or
                    otherwise covered      authorizations already
                    under current          specified in the current HMR.
                    regulations.           For example, these SPs will
                                           be terminated as they are no
                                           longer necessary since the
                                           provisions contained within
                                           have already been adopted or
                                           have been covered under
                                           current regulations.
------------------------------------------------------------------------

    The SPCP evaluated 1,168 permits that represented 3,691 holders of 
SPs that were active on January 1, 2013. Once the evaluation segment of 
the SPCP was completed, PHMSA identified 98 active SPs that were 
suitable for adoption in this proceeding. Since that time, SP-14422 has 
become no longer active and its provisions are not adopted in this 
final rule. Additionally, SP 4850 is not adopted in this final rule 
based on concerns that certain elements in its codification no longer 
communicated the exceptions from the HMR provided by the SP. Thus, we 
believe any additional burden not proposed in the January 30, 2015 NPRM 
would require notice and comment
    Adoption of the 96 SPs in this final rule will impact 832 SP 
holders as indicated in Table 6. The SPs adopted in this rulemaking 
represent an approximate 8% reduction in the number of active SPs and 
an approximate 23% reduction in the number of holders of those SPs as 
indicated in Table 6.

    It is PHMSA's intent to annually review all SPs that have been in 
effect for more than 10 years. Further, PHMSA's ongoing review and 
analysis of SPs will use the same methodology and tools as in this 
proceeding. PHMSA anticipates that future analysis and review will be 
more streamlined due to the reduction in the number of SPs to be 
evaluated and the experience gained through this evaluation.

E. SPs Suitable for Adoption

    The original analysis phase of the SPCP NPRM identified 98 SPs (728 
holders) that were deemed suitable for adoption. Further, the analysis 
phase identified 1,070 SPs that were deemed not suitable for adoption. 
Please see the January 30, 2015 NPRM for more information on the SPs 
deemed not suitable, their assigned topic area, a summary of the 
permit, the number of SP holders, and each corresponding denial code. 
In this final rule, Table 8 summarizes the SPs deemed suitable, their 
assigned topic area, a summary of the permit, and the number of holders 
of SPs. The difference in the number of holders in the NPRM (728) and 
this final rule (832) are due to seven SPs proposed for adoption in the 
NPRM that are not being adopted in this final rule and four SPs that 
were not proposed for adoption in the NPRM that are being adopted in 
this final rule. All suitable SPs (96) ultimately adopted were deemed 
to be Code 1 and are adopted in this final rule.

IV. Public Comments

    In the NPRM, PHMSA welcomed comments concerning its proposed 
amendments. Specifically, PHMSA was interested in comments from SP 
holders (both those deemed suitable and those deemed not suitable for 
adoption) that are reviewed for this rulemaking.

[[Page 3647]]

    For holders of SPs deemed suitable for adoption, PHMSA requested 
comment on our determination. We stated that we were particularly 
interested in comments that confirm or refute the suitability, safety, 
and general applicability of the SPs. PHMSA also solicited comments on 
the regulatory text proposed in this proceeding. Specifically, PHMSA 
was interested in comments that address whether the proposed regulatory 
text accurately encompasses the requirements of the SP.
    For holders of SPs deemed not suitable for adoption, PHMSA also 
requested comment on our determination. We stated that we were 
particularly interested in comments that confirm or refute the 
suitability, safety, and general applicability of the SPs. We asked 
that if you are a holder of a SP that was not proposed to be adopted 
but believe it should be, you should submit material to support such an 
argument. Specifically, PHMSA requested:
     Information and arguments that support the proposed 
adoption including technical and scientific data;
     The impact of the proposed adoption including cost and 
benefits;
     The frequency of shipments made under the SP;
     The frequency of hazardous materials incidents (such as 
those described in
    Sec. Sec.  171.15 and 171.16) occurring during shipments made under 
the SP; and
     Proposed regulatory text.
    Lastly, PHMSA requested comment as it considers a future proposed 
requirement for a SP applicant to provide potential regulatory text as 
part of each SP application.
    In response to the January 30, 2015 NPRM, PHMSA received 22 sets of 
public comments. All were supportive of PHMSA's actions to reduce the 
number of active SPs. Specifically, commenters to the NPRM were as 
follows in Table 9:

A. General/Administrative

    DSC expresses its concern about the disposition of SPs adopted into 
the HMR. It asks what happens to SPs once they are adopted into the 
HMR, and if there will be a phase-in period. DSC also asks, if the 
adoption of a SP is unacceptable to a grantee or grantees, will the SP 
still be an available option? It also asks will this rulemaking affect 
the application of future SPs.
    PHMSA notes that as the intention of this rulemaking is to adopt 
the provisions of certain SPs into the HMR, those affected SPs will be 
allowed to expire. However, PHMSA is providing a one-year effective 
date to allow current grantees sufficient time to transition from the 
provisions of their SPs to the new requirements being adopted into the 
HMR. In addition, if the adoption of a SP proves to be unacceptable to 
a grantee, a renewal or modification in accordance with 49 CFR 107.121 
will still be allowed. This rulemaking will not affect the application 
for future SPs as the requirements to apply for a SP are not being 
revised, and the SP program will continue as permitted by law. Air 
Products asks if PHMSA will provide a timeline/updates for ``other'' 
rulemaking proceedings that may have SPs under consideration for 
adoption in the HMR. PHMSA will continue to provide updates pertaining 
to other rulemaking proceedings that may have SPs under consideration 
for adoption into the HMR through its existing channels which include 
the semi-annual agenda, rulemaking activities, and Federal Register 
notices.
    In the NPRM, PHMSA solicited input regarding applicants being 
required to submit proposed regulatory text with SP applications. PHMSA 
acknowledges mixed support from affected entities on this issue. For 
example, Veolia and Dow support adoption of such policy while COSTHA 
and ACA do not. IME supports such policy as an option for an applicant.
    IME is concerned that PHMSA will conduct SP reviews for potential 
adoption on a biennial basis rather than an annual basis as implied 
through MAP-21 legislation. As noted elsewhere in this preamble, PHMSA 
intends to perform SP evaluations on an annual basis; however, 
rulemaking actions as a result may take more time as necessary.
    Lastly, PHMSA's final regulations issued in its final rule entitled 
``Hazardous Materials: Special Permit and Approvals Standard Operating 
Procedures and Evaluation Process,'' under Docket No. PHMSA-2012-0260 
(HM-233E; 9/10/15, 80 FR 54418, FR Doc. 2015-22617), contain minor

[[Page 3648]]

editorial errors in two definitions in adopted in Sec.  107.1 
concerning special permits and approvals. PHMSA is correcting those 
definitions in this final rule.

B. Cylinders--General

    No comments were received regarding the SPs proposed for adoption 
under this category. PHMSA did, however, receive comments requesting 
reconsideration of certain SPs not proposed for adoption.
Comments Requesting Reconsideration
    COSTHA requests that reconsideration be given to adopt portions of 
SPs 12726 and 15277 (aircraft fire extinguishers) to allow them to be 
described in transportation as UN1044, Fire extinguishers. PHMSA notes 
this issue is under consideration in another rulemaking action under 
docket PHMSA-2011-0140 (RIN 2137-AE80 (HM-234)). COSTHA also requests 
that reconsideration be given to adopt SP 10898 in Sec.  173.306(f) 
related to accumulators. Because neither SP was proposed for adoption 
in the NPRM, neither SP is being adopted in this final rule.

C. Cylinders--NDT/Aerosols

    CSPA is supportive of the adoption of SP 11296 and its expansion 
beyond flammable aerosols only (as proposed in the NPRM).
    CSPA and DSC generally support adoption of SP 12573 (and the 
consolidation with SP 13581) as proposed. They are, however, concerned 
with the supposed arbitrary increase in reference temperature and 
pressure with the new DOT 2Q1 standard currently authorized for 
refrigerant gases in Sec.  173.304. DSC suggests a single requirement 
of 210 psig at 55 [deg]C (131 [deg]F). It also suggests that such 
arbitrary actions if adopted could increase the number of SP 
applications submitted as a result. PHMSA recognizes the commenters' 
concerns; however, changing the reference temperature for the 
refrigerant gases to 54.4 [deg]C (130 [deg]F) would make section 
173.304(d) inconsistent with the other sections for the filling of 
gases. As noted in the NPRM, PHMSA sought to have consistency where 
some sections referred to 54.4 [deg]C (130 [deg]F) and some to 55 
[deg]C (131 [deg]F). PHMSA is therefore keeping the reference 
temperature used for maximum pressure in a container at 55 [deg]C (131 
[deg]F) as proposed in the NPRM. In order to address the commenters' 
concerns, PHMSA is raising the proposed maximum pressure authorized in 
the new DOT 2Q1 container to 210 psig at 55 [deg]C (131 [deg]F) as 
authorized in Sec. Sec.  173.304 and 173.306. The burst pressure of the 
DOT 2Q1 will have to be raised slightly accordingly to provide for the 
same safety factor. This will be discussed in a later section.
    CSPA and DSC generally support adoption of the consolidated SPs 
7951, 13601, and 14503 as proposed. They are again, however, concerned 
with the increase in reference temperature and pressure. CSPA is also 
concerned that the new relationship proposed between a pressure relief 
device (PRD) and an end expansion device, and the arbitrary upper 
boundaries adopted should instead be simply required to operate prior 
to burst. CSPA and DSC suggest as an alternative that ``the requirement 
could be defined differently for an end expansion device specifically 
versus the PRD using the language in SP 13601 that requires that the 
end buckle before burst and that the container not burst below 270 
psig.''
    CSPA and DSC correctly point out that the methodology used in the 
``if/then'' table for the use of a DOT 2P or DOT 2Q aerosol on page 
5439 [of the NPRM] is actually reversed and would lead to not allowing 
(by choice) a higher integrity container as a result. PHMSA agrees with 
the commenters and is revising the tables in Sec.  173.306 accordingly.
    CSPA generally supports adoption of the new DOT 2Q1 container as 
proposed.
    DSC suggests that the new DOT 2P1 specification should be limited 
to refrigerated foodstuffs only as prescribed in SPs 13601, 14503, and 
7951. Further, DSC recommends that the new DOT 2P1 specification not be 
expanded to authorize Division 2.1 flammable gases. However, in its 
comments, DSC does not provide support as to why the new DOT 2P1 
specification should be limited to refrigerated foodstuffs and Division 
2.2 (nonflammable) gases only.
    DSC recommends that foodstuffs in refrigerated DOT 2P1 cans be 
excepted, as they currently are under the SPs, from the hot water bath 
test. PHMSA notes that refrigerated foodstuffs in aerosol cans under 
Sec.  173.306(b) will continue to be excepted from hot water bath 
testing when the three SPs are adopted in the HMR.
    CSPA supports consolidation of SPs 14429, 14623, 14625, 14627, 
14723, 14724, 14786, 14842, 14887, 14953, 15135, 15265, 15427, and 
15972 (hot water bath test alternative), SP 14440 (weight test), and SP 
14544 (weight and leakage test) as proposed.
    DSC is concerned as to what will happen to SPs once adopted into 
the HMR and whether there will be a phase-in period. It asks because of 
substantial costs and other impacts due to relabeling of product, etc. 
Dow and CSPA support adoption of SP 12995, with Dow asking that 
sufficient time be allotted to deplete existing inventory.
    In response, PHMSA notes there is a one-year transition period 
provided to affected entities in this final rule. Further, as 
prescribed in Sec.  173.23(h), a packaging that is permanently marked 
with a SP number, ``DOT-SP'' or ``DOT-E,'' for which the provisions of 
the SP have been incorporated into the HMR may continue to be used for 
the life of the packaging without obliterating or otherwise removing 
the SP number.
Comments Requesting Reconsideration
    CSPA strongly asserts that reconsideration should be given to 
adopting SP 11516, which authorizes transportation in commerce of 
aerosols that do not meet the HMR definition of an aerosol (e.g., 
expels propellant only). CSPA suggests that PHMSA should adopt the 
international United Nations (UN) and the Globally Harmonized System 
(GHS) definition of an aerosol. In its comments, CSPA claims that DOT 
committed to adopting the international aerosol definition while it was 
involved with developing the GHS flammability standard. CSPA also 
states ``it is vitally important that DOT maintain 11516 (and other 
related SPs) as is.''
    Although PHMSA appreciates the comments pertaining to SP 11516, 
until such a time that PHMSA participates in an open and transparent 
debate on this issue (redefining the term ``aerosol''), SPs such as SP 
11516 and the like will remain valid under current policy and 
definitions.

D. Cargo Tanks/Rail Cars/Portable Tanks

    No comments were received regarding the SPs proposed for adoption 
under this category. PHMSA did, however, receive comments requesting 
reconsideration of certain SPs not proposed for adoption.
Comments Requesting Reconsideration
    In its comments, The Chlorine Institute (CI) recommends that 
reconsideration be given to adopt SP 9694 and 10457. These SPs 
authorize the transportation in commerce of chlorine contained in MC 
331 cargo tanks equipped with angle valves, excess flow valves and 
pressure relief valves not presently authorized in the HMR. Because 
neither SP was proposed for adoption in the NPRM, neither SP is being 
adopted in this final rule.
    In its comments, The CI recommends that reconsideration should be 
given to

[[Page 3649]]

adopt SP 15647. This SP authorizes the retesting of certain DOT 
specification and non-DOT specification multi-unit tank car tanks 
without approval from the Association of American Railroads (AAR). 
PHMSA notes that SP 15647 is under consideration for adoption into the 
HMR in a separate advance notice of proposed rulemaking (ANPRM) under 
docket PHMSA-2012-0082 (HM-251).
    Lastly, the CI recommends that reconsideration should be given to 
adopt SP 9166 and SP 11903 under Petition for Rulemaking (P-1608) and 
related SPs 10878, 12516, 14275, 14277, 14779, and 15552. These SPs 
authorize the manufacture, marking, sale, and use of a non-DOT 
specification glass fiber reinforced plastic (GFRP) cargo tank 
conforming with all regulations applicable to a DOT specification 407/
412 for transportation in commerce of certain hazardous materials. 
PHMSA notes it is working to develop a uniform standard for FRP cargo 
tanks and will address this issue in a future rulemaking.

E. Operational Air/Vessel

    COSTHA supports future consideration of SP 11110 under Petition for 
Rulemaking P-1610. As previously noted, COSTHA submitted a petition for 
rulemaking under P-1610 to adopt the provisions of SP 11110 into the 
HMR. This SP authorizes cargo aircraft operators to stow Division 1.4S 
and Class 8, PG III materials in inaccessible cargo locations in excess 
of the limitations specified in Sec.  175.75(c). This petition has been 
accepted by PHMSA for consideration in a future rulemaking; however, 
more time is needed to research the potential impact of changes to 
Sec.  175.75 and to coordinate this review with the appropriate 
parties, including our modal partners.
    Based on comments from PCSD, proposed Special provision ``W11'' in 
Sec.  172.102 is being replaced by revising Sec.  176.800(a) to allow 
Class 8 (corrosive) materials that are also foodstuffs or foodstuff 
ingredients intended for human consumption to not be considered 
incompatible for segregation purposes in conformance with SP 11691.
Comments Requesting Reconsideration
    Some commenters recommended that reconsideration be given to adopt 
SP 11502 (use of International Civil Aviation Organization Technical 
Instructions (ICAO TI) for highway shipments). In their comments, 
COSTHA and UPS firmly support adoption and provide justification as to 
why the SP should be adopted. However, PHMSA notes SP 11502 is under 
consideration for adoption into the HMR in a separate, broader, and yet 
unassigned air-specific rulemaking action.
    Arkema recommends that reconsideration should be given to adopt SP 
12879 into the HMR. This SP authorizes the transport of IBCs containing 
combustible liquids without placards or identification numbers in 
sealed freight containers consigned for export. Because SP 12879 was 
not proposed for adoption in the NPRM, the SP is not being adopted in 
this final rule; however, we may reconsider its codification in a 
future proceeding as appropriate.

F. Operational Highway/Rail/Shipper/Other

    PHMSA acknowledges COSTHA's support for the adoption of petitions 
for rulemaking P-1607 (SP 11458) and P-1611 (SP 11470) into the HMR in 
this proceeding.
    IME supports the adoption of SP 4850 as proposed. This SP 
authorizes the transportation in commerce by motor vehicle, rail 
freight, cargo vessel, and cargo aircraft of limited quantities of 
certain approved explosive articles (UN0237, charges, shaped, flexible, 
linear; and UN0104, cord, detonating, mild effect or fuse, detonating, 
mild effect metal clad) re-classed as Division 1.4D in prescribed 
packagings, subject to certain special provisions.
    Veolia supports the adoption of SP 11055. Further, Veolia supports 
adoption of SP 11470 with one major modification--the HMR should not be 
limited to ``expired'' products but rather should include all consumer 
commodities shipped for disposal/recycling under manufacturer recalls, 
off-spec/unwanted/unneeded product, etc. PHMSA agrees with Veolia and 
is revising Sec.  173.306(k) accordingly.
    COSTHA and DGAC support the adoption of SPs 11352, 12207, 12306, 
13165, and 14945. However, according to COSTHA, the proposed regulatory 
text in Sec.  177.820 appears to be more restrictive than the 
exceptions currently in Sec.  171.1(d)(4). After further consideration, 
we agree with COSTHA and are not adopting the five SPs in this final 
rule as proposed in the NPRM.
    Dow supports the adoption of SP 9874, SP 14822, and the eight 
related SPs. In its comments, Dow supports codification of the SPs but 
has specific concerns: (1) SP 9874 and 14822 authorize instrumentation 
and signaling systems such as sensors, alarms, and electronic 
surveillance equipment in addition to video monitoring; (2) SP 9874 and 
14822 do not require a video camera with a ``motorized zoom lens 
capable of panning and zooming from the remote control station''; (3) 
SP 9874 and 14822 do not require that the view capability must include 
the entire containment area; and (4) Dow wants assurance that the 
attendance requirements in Sec.  177.834 (i) apply to motor carriers 
only. We agree that Dow's comments have merit and, in this final rule, 
except for number (4), the regulatory text in Sec.  177.834(i) is 
revised accordingly. Regarding issue number (4), long-standing 
interpretations preclude the need to revise the attendance 
applicability provisions of the HMR. As a result of Dow's concerns, 
Sec.  177.834 (i) is revised accordingly in this final rule.
    In its comments, Eli expresses it support for the adoption of SP 
14150 in Sec.  177.834(i)(3)(ii) as proposed. SP 14150 authorizes use 
of video cameras and monitors to observe the loading and unloading 
operations of certain Class 3 and Class 8 hazardous materials from a 
remote control station in place of personnel remaining within 7.62 
meters (25 feet) of cargo tank motor vehicles. Lastly, PCTI supports 
adoption of SP 11352 as proposed in Sec.  177.820.
    Veolia supports the adoption of SP 11043. However, it notes that 
the regulatory text proposed in Sec.  177.840(a)(3)(i) should be 
revised to require a 4-foot separation rather than a 5-foot separation 
for consistency with the segregation spacing requirements found in 
Sec.  173.12(e). We agree with Veolia's comment and are revising Sec.  
177.840(a)(3)(i)(C) accordingly.
    Veolia supports adoption of SP 11984 with one major modification--
the HMR should require flame-proof outer packaging for chemical oxygen 
generators shipped with only one positive means of preventing 
unintentional activation as expressed in concern for equivalent level 
of safety in proposed SP modification in August 2011. After additional 
review, in this final rule, we are adopting the provisions of SP 11984 
as proposed into Sec.  173.168.
    In the NPRM, PHMSA proposed to add Special Provision 383 to adopt 
SP 11356. This SP authorizes certain materials meeting the conditions 
for high viscosity flammable liquids specified in Sec.  
173.121(b)(1)(i), (b)(1)(ii), and (b)(1)(iv), to be reassigned to 
Packing Group (PG) III for transportation by motor vehicle. The SP 
prescribes packaging, capacity limitations, and load securement 
requirements. We proposed to adopt the provisions of the SP in its 
entirety in this new special provision for the following entries: 
Coating solution (UN1139, PG II) and paint (UN1263, PG II). In its 
comments,

[[Page 3650]]

ACA requests that PHMSA expand the materials authorized for 
reclassification to include: (1) UN1866, Resin solution, PG II; (2) 
UN1210, Printing ink, PG II; and (3) UN1133, Adhesives, PG II. We agree 
with ACA and are revising the HMT for the requested entries 
accordingly.
    In the NPRM, we proposed to add a new paragraph (h) to Sec.  173.12 
to adopt the provisions of SP 11470 in its entirety. In its comments, 
ACA is concerned that ``stretch-wrapped'' pallets would not be able to 
take advantage of the exceptions provided for ``shrink-wrapped'' 
pallets. Further, ACA suggests that the proposed regulatory text limits 
the type of packages to ``boxes.'' We agree and are revising Sec.  
173.12(h) to explicitly allow ``stretch-wrapped'' pallets and any 
authorized type of packaging.
    Section 174.67 establishes specific operational requirements for 
railroad tank car unloading. For combustible liquids or Class 3 liquid 
petroleum distillate fuels, SP 12002 authorizes clearing frozen liquid 
blockages from the outlet by attaching a fitting to the outlet line and 
applying nitrogen at a pressure of 50 to 100 psi. In the NPRM, we 
proposed to revise paragraph (g) to Sec.  174.67 to adopt the 
provisions of SP 12002 in its entirety. In its comments, ACA recommends 
that the use of nitrogen should be permitted ``at a pressure of up to 
100 psi'' for clarity. We agree with ACA and are revising Sec.  
174.67(g) accordingly.
    In its comments, DGAC supports adoption of SP 11666 as Sec.  
172.102(c)(1), Special Provision 384. It does, however, comment on the 
use of the word ``sifting'' which should actually be ``shifting'' and, 
further, the SP permits stacking two or more levels high to achieve 
maximum allowable utilization of the designated vehicle, rail car 
weight, or intermodal freight container weight or vessel hold volume. 
We agree with DGAC's comments and the special provision is revised 
accordingly.
    DGAC supports the adoption of SP 14525 and correctly points-out 
some discrepancies in preamble discussion of its adoption in new Sec.  
172.102(c)(3), Special Provision B130. We agree with DGAC's comments 
and revise the preamble discussion and regulatory text accordingly.
Comments Requesting Reconsideration
    IME and COSTHA firmly support that reconsideration should be given 
to adopt SP 14282. This SP authorizes transportation in commerce of 
certain detonators, detonator assemblies, detonators for ammunition, 
detonating fuses and igniting fuses on the same motor vehicle with any 
other Class 1 explosives. Because SP 14282 was not proposed for 
adoption in the NPRM, the SP is not being adopted in this final rule.
    Veolia comments that reconsideration should be given to adopt SP 
12998. This SP authorizes the transportation in commerce of lab packs 
containing materials that are not waste materials by private or 
contract carrier from one laboratory to another within the same 
company. Because SP 12998 was not proposed for adoption in the NPRM, 
the SP is not being adopted in this final rule.
    Veolia comments that reconsideration should be given to adopt SP 
12102. This SP authorizes transportation in commerce of certain 
unapproved desensitized explosives. Because SP 12102 was not proposed 
for adoption in the NPRM, the SP is not being adopted in this final 
rule.
    Veolia comments that reconsideration should be given to adopt SP 
13179. This SP authorizes transportation in commerce of certain 
approved lighters which have been removed from their inner packaging 
and are being sent for disposal. Because the SP indicated Code 5 
(already adopted or otherwise covered under current regulations as the 
reason it was considered not suitable for adoption), Veolia asserts 
PHMSA will terminate the SP and therefore, its provisions either need 
to be adopted into the HMR in this rulemaking or the SP should not be 
terminated. We sincerely apologize for any confusion this may have 
caused as we mistakenly miscoded SP 13179 in the NPRM. In hindsight, SP 
13179 should have been a Code 2 or 3 as not suitable for adoption. 
Further, because SP 13179 was not proposed for adoption in the NPRM, 
the SP is not being adopted in this final rule nor do we intend to 
terminate it at this time.
    For highway transportation by private carrier, SP 11197 provides 
relief from the requirement to display the limited quantity marking on 
packages containing materials assigned to PG II and III and prepared in 
accordance with the limited quantity requirements in Part 173. In its 
comments, ACA claims the regulatory text is not clear regarding its 
application but did not provide alternative language. Consequently, the 
language is adopted as proposed.
    Gulf Coast, RIBCA-NA, and CI recommend that reconsideration should 
be given to adopt SP 12412 into the HMR as there are 322 companies as 
grantees. This SP authorizes discharge of liquid hazardous materials 
from certain UN intermediate bulk containers (IBCs) and DOT 
specification 57 portable tanks without removing them from the vehicle 
on which they are transported. Because SP 12412 was not proposed for 
adoption in the NPRM, the SP is not being adopted in this final rule.
    Estes-Cox firmly supports the adoption of SP 7887 and comments that 
reconsideration should be given. This SP authorizes certain Class 1 
articles in small amounts to be reclassed as Division 4.1 flammable 
solid, organic, n.o.s. It applies to small ``single-use expendable'' or 
``reloadable'' rocket motors first classed as Division 1.4C or 1.4S 
(NA0323 or NA0276) shipped with or without their igniters classed as 
Division 1.4G or 1.4S under Sec.  173.56. Because SP 7887 was not 
proposed for adoption in the NPRM, the SP is not being adopted in this 
final rule.

G. Non-Bulk Packaging Specifications/IBCs

    IME supports the adoption of SP 12335, which authorizes 
transportation in commerce of certain Division 1.1D and 1.4D detonating 
cords without the ends being sealed in alternative packaging.
    SP 8230 authorizes the transportation in commerce of PG I and II 
nitric acids in certain combination packagings by motor vehicle, rail 
freight, cargo vessel and cargo-only aircraft. Specifically, ``Nitric 
acid, other than red fuming, with more than 70% nitric acid'' and 
``Nitric acid, other than red fuming, with not more than 70% nitric 
acid'' is authorized to be transported in inner plastic bottles in 
rigid foam plastic receptacles or plastic bags lined with absorbent 
material in outer packagings. In its comments, UPS supports adoption of 
SP 8230 in Sec.  173.158(j) as proposed.
    Section 173.158 provides general requirements and exceptions for 
shipments and packagings of nitric acid. In the NPRM, we proposed to 
establish a new paragraph (i) to authorize ``Nitric acid of up to 40% 
concentration'' in a UN1H1 non-removable head plastic drums with 
certain conditions as prescribed in SP 14213. In its comments, Mauser 
questioned why SP 9722 was not also proposed for adoption as it is 
identical to Greif's SP 14213. After additional review, we agree and in 
this final rule are also adopting the provisions of SP 9722 into Sec.  
173.158 accordingly.
    DGAC supports the adoption of SP 9610 with edits. However, the SP 
was revised in November 2014 after review of the SPs as part of this 
proceeding. We agree with the revisions made to the SP. Therefore, in 
this final rule, we are revising new paragraph Sec.  173.29(f) to 
address the DGAC edits and the 2014

[[Page 3651]]

revisions to the SP, specifically, to include fiberboard boxes as 
authorized packagings for empty packagings containing the residue of 
smokeless powders.
Comments Requesting Reconsideration
    IME and COSTHA firmly support that reconsideration should be given 
to adopt SP 8451. This SP authorizes transportation in commerce of not 
more than 25 grams of solid explosive or pyrotechnic material, 
including waste-containing explosives that have an energy density not 
significantly greater than that of pentaerythritol tetranitrate (PETN), 
classed as Division 1.4E, when packed in a special shipping container. 
Because SP 8451 was not proposed for adoption in the NPRM, the SP is 
not being adopted in this final rule.
    IME firmly supports that reconsideration should be given to adopt 
SP 10880. This SP authorizes the transportation in commerce of ammonium 
nitrate-fuel oil mixture (ANFO), Division 1.5, in reusable, flexible 
intermediate bulk containers (IBCs) type UN 13H3 or UN 13H4 conforming 
to Subpart N and O of Part 178. Because SP 10880 was not proposed for 
adoption in the NPRM, the SP is not being adopted in this final rule.
    IME and COSTHA firmly support that reconsideration should be given 
to adopt SP 11156. This SP authorizes transportation in commerce of 
NA0331, UN1942 and UN0331 in non-DOT specification multi-wall plastic-
lined paper bags. Because SP 11156 was not proposed for adoption in the 
NPRM, the SP is not being adopted in this final rule.
    SP 11624 was not proposed for adoption in the NPRM. The SP is in 
its fifteenth revision and has 114 grantees. The SP authorizes 
transportation in commerce of certain waste Class 3 paint and paint 
related material (UN1263; PG II and PG III) contained in metal or 
plastic pails further packed in non-specification bulk packagings such 
as cubic yard boxes, plastic rigid-wall bulk containers, dump trailers, 
and roll-off containers. In their comments, Veolia, ACA, and DGAC 
provided substantial justification why reconsideration should be given 
to adopt SP 11624 into the HMR. Therefore, after revaluation, SP 11624 
and three related packaging SPs (i.e., SP 13052, SP 14712, and 15235) 
are adopted as new Sec.  172.102(c)(3), Special Provision B131.

V. Section-by-Section Review by Topic Area

A. Cylinders--General

Part 172
Section 172.102--Special Provisions
    Section 172.102(c) lists special provisions applicable to specific 
entries in the Hazardous Materials Table (HMT). Special provisions may 
contain packaging requirements, conditions or limitations, and 
exceptions applicable to particular quantities or forms of hazardous 
materials.
    In general, non-bulk packagings must be marked with an 
identification number and proper shipping name and bear labels 
communicating the hazard of the material contained in the package. SP 
13544 authorizes the transportation in commerce of DOT Specification 
4BA240 cylinders containing liquefied petroleum gas (LPG) and propane 
and/or residue of LPG or propane without hazard warnings (i.e., hazard 
communication) provided the materials are transported in a closed and 
placarded transport vehicle. This SP supports the propane cylinder 
exchange programs that accept expended cylinders in exchange for full 
cylinders. Cylinders collected during the course of these programs may 
not always bear the appropriate hazard markings and labels as required 
by the HMR. SP 13544 prescribes certain operational controls to ensure 
appropriate hazard communication, driver training, and appropriate 
securement of the cylinder on the transport vehicle.
    In this final rule, PHMSA is adopting SP 13544 as proposed by 
adding new Special Provision, ``N95'' to Sec.  172.102(c)(5) that 
excepts cylinders containing UN1075, Liquefied petroleum gas and 
UN1978, Propane from marking the identification number and proper 
shipping name or bear hazard labels provided certain conditions are 
met. Because we did not receive public comment on this amendment, 
supportive or otherwise, it is adopted as proposed in the NPRM.
Section 172.400a
    Section 172.400a provides exceptions or alternatives to the HMR 
labeling requirements under specific circumstances. One such 
alternative permits the use of a neckring marking, under certain 
conditions, in accordance with the Compressed Gas Association (CGA) 
Pamphlet C-7, Guide to Preparation of Precautionary Labeling and 
Marking of Compressed Gas Containers, Appendix A, 8th Edition (2004). 
Section 172.400a permits the use of a CGA Pamphlet C-7 marking in lieu 
of the required 100 mm x 100 mm square-on-point labels on a Dewar flask 
meeting the requirements in Sec.  173.320 and on cylinders containing 
Division 2.1, 2.2, and 2.3 materials that are not overpacked.
    SP 14251 authorizes the transportation of overpacked cylinders, 
containing Class 2 materials, with CGA C-7 neckring markings provided 
the overpack is labeled in accordance with Sec.  172.400. Additionally, 
the CGA petitioned PHMSA (under petition P-1521) to allow cylinders to 
display the neckring marking even when overpacked. The petition, if 
adopted, would still require the overpack to display the 100 mm x 100 
mm square-on-point labels in accordance with 49 CFR Part 172, Subpart 
E. The marking prescribed in Appendix A to CGA Pamphlet C-7 provides 
useful information in a clear and consistent manner and its widespread 
use on cylinders over the course of several years has enhanced its 
recognition. The adoption of SP 14251 and CGA's petition would provide 
greater flexibility for shipments of cylinders while ensuring adequate 
hazard communication. Therefore, PHMSA is revising as proposed Sec.  
172.400a by authorizing the transportation of overpacked cylinders 
marked in accordance with CGA Pamphlet C-7 provided the overpacks are 
properly labeled.
Part 173
Section 173.181
    Section 173.181 prescribes authorized packagings for the 
transportation of pyrophoric materials (liquids).
    SP 14419 authorizes the use of DOT Specification 3AL cylinders 
constructed from aluminum alloy 6061-T6 for the transportation of 
pyrophoric liquids provided: (1) The cylinders are constructed of 6061-
T6 aluminum; (2) have a minimum marked service pressure of 1800 psig; 
(3) have a maximum water capacity of 49 liters; and (4) any preheating 
or heating of the cylinders is limited to a maximum temperature of 
175[emsp14][deg]F. In this final rule, PHMSA is revising Sec.  
173.181(a) as proposed to permit the use of DOT Specification 3AL 
cylinders constructed from aluminum alloy 6061-T6, with the same 
specified conditions for the transport of pyrophoric materials.
Section 173.193
    Section 173.193(b) requires that ``Bromoacetone, Methyl bromide, 
Chloropicrin and Methyl bromide mixtures, Chloropicrin and Methyl 
chloride mixtures, and Chloropicrin

[[Page 3652]]

mixtures charged with non-flammable, non-liquefied compressed gas be 
packaged in DOT Specification 3A, 3AA, 3B, 3C, 3E, 4A, 4B, 4BA, 4BW, or 
4C cylinders having not over 113 kg (250 pounds) water capacity 
(nominal).''
    SP 12301 authorizes the transportation in commerce of Chloropicrin 
and Methyl bromide mixtures in DOT 4BW cylinders with water capacity 
(nominal) not over 454 kg (1,000 pounds). In this final rule, PHMSA is 
adopting as proposed the revisions to Sec.  173.193(b) that allow for 
Chloropicrin and Methyl bromide mixtures to be packaged in DOT 
specification 4BW cylinders with a water capacity of not over 454 kg 
(1,000 pounds).
Section 173.301
    Section 173.301 prescribes the general requirements for the use of 
cylinders including a list of authorized cylinders, general filling 
requirements, valve protection, and pressure relief device 
requirements. In the NPRM, we proposed revisions that would amend 
certain pressure relief device requirements and permit the use of valve 
caps made from a material other than metal as authorized under the 
terms of three SPs.
    SP 13318 authorizes the transportation in commerce of DOT 
Specification 39 cylinders of 75 cubic inches or less volume, without 
the PRD in direct communication with the vapor space. PHMSA proposed to 
amend paragraph (f)(2) to state that this provision does not apply to 
cylinders of 75 cubic inches or less in volume filled with a Liquefied 
petroleum gas, Methyl acetylene and Propadiene mixtures, stabilized, 
Propylene, Propane or Butane. Because we did not receive public comment 
on this amendment, supportive or otherwise, it is adopted as proposed 
in the NPRM.
    SP 8074 provides an exception from the PRD requirements for a DOT 
Specification 3E cylinder up to 12 inches long and 2 inches in diameter 
when filled with the following gases and associated quantity limits: 
Carbon dioxide, liquefied 0.24L (8 oz.), Ethane 0.12L (4 oz.), Ethylene 
(4 oz.), Hydrogen chloride, anhydrous 0.24L (8 oz.), Nitrous oxide 
0.24L (8 oz.), Vinyl fluoride, stabilized 0.24L (8 oz.) and 
Monochlorotrifluoromethane 0.35L (12 oz.). In the NPRM, PHMSA proposed 
to create an additional exception to PRD requirements for DOT-3E 
cylinders under limited circumstances in new paragraph Sec.  
173.301(f)(7). Because we did not receive public comment on this 
amendment, supportive or otherwise, it is adopted as proposed in the 
NPRM.
    SP 12782 authorizes plastic valve protection caps for certain 
Division 2.1, 2.2, and 2.3 materials when the valve protection is 
sufficient to prevent leakage when the cylinder, with the valve 
installed, is dropped from 2.0 m (7 ft) or more onto a non-yielding 
floor, impacting the valve assembly or cap at the orientation most 
likely to cause damage. The HMR require that each cylinder with a valve 
must have a protective metal cap, other valve protection device, or an 
overpack which is sufficient to protect the valve from damage during 
transportation. In the NPRM, PHMSA proposed to amend Sec. Sec.  
173.40(d) and 173.301(h) to allow for the new valve protection 
standard, including the valve cap, to be made from plastic as 
authorized in SP 12782. Because we did not receive public comment on 
this amendment, supportive or otherwise, it is adopted as proposed in 
the NPRM.
Section 173.302a
    Sections 173.302, 173.302a, 173.304 and 173.304a prescribe 
additional requirements for the transport of non-liquefied (permanent) 
and liquefied compressed gases in DOT specification cylinders. These 
requirements include authorized cylinders and filling limits. Section 
173.302a(b) states that a DOT 3A, 3AA, 3AX, 3AAX, and 3T cylinder may 
be filled with a compressed gas, other than a liquefied, dissolved, 
Division 2.1, or Division 2.3 gas, to a pressure 10% in excess of its 
marked service pressure, subject to certain criteria.
    SP 6530 authorizes the transport in commerce of hydrogen and 
mixtures of hydrogen with helium, argon, or nitrogen, in certain 
cylinders filled to 10% in excess of their marked service pressure. In 
the NPRM, PHMSA proposed to add a new paragraph (c) to include this 
exception and to redesignate the other paragraphs in this section to 
reflect this addition. Because we did not receive public comment on 
this amendment, supportive or otherwise, it is adopted as proposed in 
the NPRM with the exception of an editorial correction. In the NPRM, 
paragraph (c)(3)(ii) stated that cylinders manufactured with chrome 
moly steel must have been normalized. The paragraph has been corrected 
to state that the steel must have been quenched and tempered, not 
normalized. In addition the paragraph (c)(4) the term safety relief 
devices has been corrected to pressure relief devices for consistency 
with current regulations.
Section 173.304a
    In Sec.  173.304a(a)(2), a table provides the maximum filling 
densities and permissible cylinder types for certain named gases. 
Currently, Sec.  173.304a(a)(2) permits a maximum filling density of 
68% for carbon dioxide and nitrous oxide in DOT 3, DOT 3HT2000 and DOT 
39 cylinders, and DOT 3A, 3AA, 3AX, 3AAX, 3E, 3T, and 3AL cylinders 
with a marked service pressure of 1800 psi.
    SP 13599 authorizes additional maximum filling densities for carbon 
dioxide and nitrous oxide to include 70.3%, 73.2%, and 74.5% 
respectively in DOT 3A, 3AA, 3AX, 3AAX, 3AL, and 3T cylinders with 
marked service pressures of 2000, 2265, and 2400 psig, subject to 
operational controls. Air Products and Chemicals Inc. (Air Products) 
submitted a petition for rulemaking (P-1560) requesting PHMSA revise 
Sec.  173.304a(a)(2) to adopt the provisions of SP 13599. In the NPRM, 
PHMSA proposed to modify the entries currently in the table in Sec.  
173.304a(a)(2) to add additional filling densities for carbon dioxide 
and nitrous oxide. Because we did not receive public comment on this 
amendment, supportive or otherwise, it is adopted as proposed in the 
NPRM.
Part 180, Subpart C
Qualification, Maintenance and Use of Cylinders
    The HMR prescribe requirements for the continuing qualification, 
maintenance, and periodic requalification of DOT specification 
cylinders, DOT SP cylinders, and UN pressure receptacles. These 
requirements ensure that cylinders conform to the appropriate 
specification and compromised cylinders are not filled with hazardous 
materials. The discussion of the proposed amendments includes a 
section-by-section review of the current requirements, and a brief 
discussion of SPs considered for adoption and proposed amendments.
Section 180.209
    Paragraph (e) of Sec.  180.209 authorizes a proof pressure test in 
lieu of the volumetric expansion test for 4B, 4BA, 4BW, or 4E cylinders 
protected with a corrosion resistant coating and used exclusively for 
the gases specified in that paragraph.
    SP 12084 expands the list of authorized gases in paragraph (e). 
These gases include refrigerated and liquefied gases similar to those 
already permitted by Sec.  180.209(e). In the NPRM, PHMSA proposed to 
adopt the provisions in SP 12084 by removing the list of authorized

[[Page 3653]]

gases and authorizing the use of the proof pressure test for DOT-4B, 
4BA, 4BW, or 4E cylinders protected externally by a suitable corrosion 
resistant coating and used exclusively for non-corrosive gases. The 
authorized specifications limit the total pressure in the cylinder to 
500 psi or less. Because we did not receive public comment on this 
amendment, supportive or otherwise, it is adopted as proposed in the 
NPRM.
Section 180.213
    Cylinders requalified in accordance with the HMR must bear 
requalification markings in accordance with Sec.  180.213. As provided 
in Sec.  180.213(c), ``The depth of requalification markings may not be 
greater than specified in the applicable specification. The markings 
must be made by stamping, engraving, scribing or other method that 
produces a legible, durable mark.''
    SP 14937 allows the use of a label embedded in epoxy in lieu of 
other methods prescribed in Sec.  180.213. In the NPRM, PHMSA proposed 
to amend paragraph (c) to allow the use of a label embedded in epoxy in 
lieu of stamping provided the marking is legible and durable. Because 
we did not receive public comment on this amendment, supportive or 
otherwise, it is adopted as proposed in the NPRM.

B. Cylinders--Non-Destructive Testing/Aerosols

Part 173
Section 173.304
    Section 173.304 prescribes requirements for the filling of 
cylinders with liquefied compressed gases. Paragraph (d) of this 
section provides for authorized containers for the filling of cylinders 
with refrigerant and dispersant gases. Current regulations authorize 
these gases in DOT 2Q non-refillable metal containers.
    SP 12573 authorizes a refrigerant gas R 134a, (UN3159), in a non-
DOT specification container similar to a DOT 2Q container with a 
maximum allowable pressure for the contents of 198 psig at 54.4 [deg]C 
(130[emsp14][deg]F). In the NPRM, we differed marginally from the SP 
and proposed to adopt a maximum pressure threshold of 200 psig at 55 
[deg]C (131[emsp14][deg]F) for the container's contents. We indicated 
there was no safety basis for the 200 psig ceiling other than we 
believed it was a cleaner cutoff point than the 198 psig maximum found 
in the SP. In addition, as part of the variation on the design of a DOT 
2Q container, we proposed the modified container would be marked as a 
``DOT 2Q1.''
    Current regulations require that the pressure of the contents of 
the metal containers not exceed 87 psig at 21 [deg]C 
(70[emsp14][deg]F). In the NPRM, we invited comment on whether the 
requirement for a maximum pressure should be specified at 21 [deg]C 
(70[emsp14][deg]F) for the 2Q1 container in addition to the limit at 55 
[deg]C (131[emsp14][deg]F). If so, we invited comment on what the upper 
limit should be for a typical refrigerant or dispersant gas such as 
1,1,1,2 Tetrafluoroethane, R134a.
    In its comments, DSC suggests a single requirement of 210 psig at 
55 [deg]C (131[emsp14][deg]F). It also suggests that such arbitrary 
actions if adopted could increase the number of SP applications 
submitted as a result. PHMSA recognizes the commenters concerns, 
however, changing the reference temperature for the refrigerant gases 
to 54.4 [deg]C (130[emsp14][deg]F) would make section 173.304(d) 
inconsistent with the other sections for filling of gases. As noted in 
the NPRM, PHMSA sought to have consistency where some sections referred 
to 54.4 [deg]C (130[emsp14][deg]F) and some to 55 [deg]C 
(131[emsp14][deg]F). In order to address the commenters concerns, PHMSA 
is raising the proposed maximum pressure authorized in the new DOT 2Q1 
container to 210 psig at 55[deg]C (131[emsp14][deg]F) as authorized in 
Sec. Sec.  173.304 and 173.306. The burst pressure of the DOT 2Q1 will 
have to be slightly raised accordingly to provide for the same safety 
factor. This will be discussed in a later section. See the associated 
discussion in the comments received from Dow earlier in this preamble.
Section 173.306
    Section 173.306 prescribes the general requirements and exceptions 
for limited quantities of compressed gases. In the NPRM, we proposed 
numerous changes to this section. The proposed changes and resolutions 
are discussed in the following.
Conforming Revisions
    Throughout Sec.  173.306 of the HMR and within related SPs that 
provide exemptions from these regulations for gases, pressure standards 
are indicated at either 130[emsp14][deg]F or 131[emsp14][deg]F. In the 
interest of consistency and conformity with the general requirements 
for compressed gases in Sec.  173.301 and 173.301a, in the NPRM we 
proposed to change all references of 54.4 [deg]C (130[emsp14][deg]F) to 
55 [deg]C (131[emsp14][deg]F). We invited comment on whether there 
would be any negative impacts in making this conforming change. We also 
proposed making revisions to the construction and formatting of how 
this section is presented (e.g., insertion of an ``if, then'' table) in 
an effort to make the requirements more reader-friendly.
Authorized Metal Containers
DOT 2P Inner Nonrefillable Metal Containers
    Under Sec.  173.306, limited quantities of foodstuffs or soaps with 
soluble or emulsified compressed gas are authorized in nonrefillable 
metal or plastic containers. The paragraph (b)(1) introductory text 
authorizes these containers subject to a pressure not to exceed 140 
psig at 54.4 [deg]C (130[emsp14][deg]F). SP 13601 and SP 14503 
authorize the transportation of ``UN1950, Aerosols, non-flammable (each 
not exceeding 1 L capacity), 2.2,'' and SP 7951 authorizes the 
transportation of ``UN1956, Compressed gas, n.o.s., 2.2,'' in 
containers that otherwise conform to DOT 2P or DOT 2Q specifications 
with some modifications. Under the terms of SP 13601, the containers 
must have a maximum pressure for the contents not to exceed 160 psig at 
54.4 [deg]C (130[emsp14][deg]F) and, for SP 7951 and SP 14503, the 
containers must have a maximum pressure for the contents not to exceed 
150 psig at 23.9 [deg]C (75[emsp14][deg]F) and must be transported in a 
refrigerated state.
    In the NPRM, we requested comments on whether refrigeration should 
be a condition of transport of these foodstuffs under pressure. In 
their comments, DSC and CSPA both recommend that PHMSA continue to 
require refrigeration as a condition of transport of these foodstuffs 
under pressure. See the comment summary section for a more detailed 
discussion of this issue. Because at least one of the special permits 
to be incorporated (SP 13601) does not explicitly require 
refrigeration, this requirement will not be adopted. Note that the 
additional limit of 150 psig at 23.9 [deg]C (75[emsp14][deg]F) is 
required. The shipper may use refrigeration if needed to achieve this 
pressure. As part of the variation of the DOT 2P containers, the 
modified containers are to be marked as ``DOT 2P1'' under the 
provisions of new Sec.  178.33c discussed separately in this 
rulemaking.
    We also proposed in the NPRM to include the specification DOT 2P1 
as an authorized metal aerosol container under Sec.  173.306(a)(3)(ii). 
We saw no reason to limit the container to foodstuffs or soaps under 
paragraph (b)(1) because the pressure limit for the contents is the 
same as the current requirement for a standard DOT 2P container. 
Lastly, we proposed that the DOT 2P1 would be authorized for both 
Division 2.1 (flammable) and 2.2 (non-flammable) aerosols under

[[Page 3654]]

Sec.  173.306(a)(3)(ii). PHMSA received negative comments on the use of 
the DOT 2P1 container for flammable gases. Because there has been no 
experience with this type of container equipped with a pressure relief 
device in flammable gas service, we will not adopt the 2P1 for any 
materials other than those authorized in the special permits 
incorporated at this time.
DOT 2Q Inner Nonrefillable Metal Containers
    Under Sec.  173.306, limited quantities of compressed gas are 
authorized in metal aerosol containers as defined in Sec.  171.8 of the 
HMR. Paragraph (a)(3) introductory text of this section authorizes 
metal aerosol containers under certain conditions to include packaging 
types and pressure thresholds. Section 173.306(a)(3)(ii) currently 
requires the use of a DOT 2Q container for pressures exceeding 160 psig 
at 54.4 [deg]C (130[emsp14][deg]F) but not to exceed 180 psig. Except 
for some modifications, SP 12573 authorizes the packaging of UN1950, 
Aerosols, non-flammable, in non-DOT specification containers that 
otherwise conform to the DOT 2Q specification with a maximum pressure 
of 198 psig at 54.4 [deg]C (130[emsp14][deg]F).
    In the NPRM, we proposed to adopt the modified DOT 2Q as an 
authorized metal aerosol container. We differed marginally from the SP 
in that we proposed to adopt a maximum pressure threshold of 200 psig 
at 55 [deg]C (131[emsp14][deg]F). We stated that there was no safety 
basis for the 200 psig ceiling other than we believed it was a cleaner 
cutoff point than the 198 psig maximum found in the SP. Additionally, 
we sought to provide consistency by using a reference temperature of 55 
[deg]C (131[emsp14][deg]F). PHMSA received comments about the negative 
impact of raising the reference temperature from 54.4 [deg]C 
(130[emsp14][deg]F) to 55 [deg]C (131[emsp14][deg]F) particularly for 
shippers of R134a which has a pressure of 198 psig at 54.4 [deg]C 
(130[emsp14][deg]F). The commenters further stated that the pressure of 
R134a at 55 [deg]C (131[emsp14][deg]F) is 202 psig and that a pressure 
of 210 psig should be adopted. Consequently, in this final rule, PHMSA 
will adopt a pressure of 210 psig at 55 [deg]C (131[emsp14][deg]F) in 
order to allow for small variations; however, the reference temperature 
will remain at 54.4 [deg]C (130[emsp14][deg]F). As part of the 
variation of the specification of a DOT 2Q container, we stated the 
modified container will be marked as ``DOT 2Q1.''
    In the NPRM, the proposed design burst pressure of the DOT 2Q1 was 
300 psig. Because the fill pressure of the DOT 2Q1 will be 210 psig at 
55 [deg]C (131 [deg]F), PHMSA will raise the design burst pressure to 
320 psig in this final rule. The pressure of 320 psig is consistent 
with the minimum design burst pressure in SP 12573.
    The NPRM also proposed to expand authorized materials to include 
Division 2.1 aerosols for the DOT 2Q1 specification. At that time, we 
saw no reason to limit the use of this container to non-flammable 
aerosols based on its record of use and that DOT 2Q containers 
currently authorized in the HMR are authorized to be used for all 
aerosol types. We also invited comment on the suitability of the 
container for all aerosol types. See the associated comment summary 
discussions for Sec. Sec.  173.304 and 178.33d. PHMSA received mixed 
comments on the use of the DOT 2Q1 container for flammable gases. 
Because there has been no experience with this type of container 
equipped with a pressure relief device in flammable gas service, we 
will not adopt the DOT 2Q1 for any materials other than those 
authorized in the special permits incorporated at this time.
    SP 13581 is linked to the above proposed provision in that it 
authorizes the use of metal aerosol containers manufactured, tested, 
and marked according to SP 12573. We believe this SP will no longer be 
needed with the adoption of the modified DOT 2Q container (i.e., a DOT 
2Q1 container).
Alternatives to Testing of Metal Aerosol Containers by a Hot Water Bath 
Test
    As a condition of the use of a metal aerosol container used for 
certain commodities, each container, after being filled, must be 
subjected to a hot water bath to raise the internal pressure to such a 
degree that leakage or permanent deformation, if any, can be determined 
[see Sec.  173.306(a)(3)(v)]. The provision also provides for a testing 
protocol for a container where the contents may be sensitive to heat. 
Currently, this is the only method authorized for determining leakage 
or permanent deformation. Thus, fillers that have developed other 
testing protocols or do not want to subject their products to a hot 
water bath test, must obtain a SP to do so. A number of SPs that 
authorize the use of alternative methods to determine leakage or 
permanent deformation are discussed as follows:
    (1) Alternate hot water bath test. SP 12995 authorizes a 
methodology that is a combination of a hot water bath test, a weight 
test, and visual inspection. Rather than subjecting each filled 
container to a hot water bath test, only one container out of each lot 
is subjected to the hot water bath test, a second is subjected to a 
weight test, the results of which must be compared to weight 
specification for the container as outlined in quality control 
procedures, and finally, the remainder of the lot must be visually 
inspected by examining the valve, crimp, and seam areas for evidence of 
leakage.
    In the NPRM, we proposed to adopt SP 12995. The permit authorizes 
only DOT 2Q containers but we are applying it to all authorized metal 
aerosol containers. While determining if SP 12995 was suitable for 
inclusion in this rulemaking, PHMSA's technical evaluators confirmed 
that the methodology that includes a combination of hot water bath 
test, weight test, and visual inspection may be performed on a DOT 2P 
as well as a DOT 2Q. Since these containers are similar designs except 
in terms of strength, this alternative to the hot water bath test is 
applicable to any metal container. Previously, most applicants of SP 
12995 only requested 2Q because that is what they needed for their 
particular hazmat, but that does not mean that alternative testing is 
not acceptable for similar containers. Additionally, the permit applies 
to specific filling conditions but we will apply this testing method to 
containers complying with the current filling conditions in Sec.  
173.306(a)(3). Finally, we vary from the permit with our proposed 
language in that we require maintenance and access to operating 
procedures especially with regard to the weight test and specification 
in order to effect a broader application of this alternative. Rather 
than specify standards, we will allow persons to develop their own 
procedures that best fit their product on the condition that DOT has 
access to these procedures. Commenters were very supportive of our 
proposals to adopt such testing alternatives and, in this final rule, 
we are codifying them as proposed.
    (2) Automated in-line pressure test. SPs 14429, 14623, 14625, 
14627, 14723, 14724, 14786, 14842, 14887, 14953, 15135, 15265, 15427, 
and 15972 all authorize the use of an automated process to check the 
pressure of filled containers (i.e., an ``automated in-line pressure 
check'') instead of subjecting the containers to a hot water bath. In 
this final rule, we are adopting the provisions of these SPs as 
proposed that authorize the use of an automated process for pressure 
checks that does not involve a hot water bath.
    (3) Weight test. SP 14440 authorizes the use of a process to check 
the weight of filled containers (i.e., an ``automated in-line pressure 
check'') instead of subjecting the containers to a hot water bath. In 
this final rule, we are adopting the provisions of the SP as proposed 
to

[[Page 3655]]

authorize the use of weight checks as a means to determine compliance 
with pressure requirements.
    (4) Leakage test. SP 14544 authorizes the use of a high pressure 
air test on empty containers combined with a leakage test for filled 
containers instead of subjecting the containers to a hot water bath. 
The testing protocol for filled containers found in this SP is 
currently applied to plastic containers under paragraph (a)(5) of this 
section in the HMR, however, the pressure and leakage test of the empty 
containers differs in its application. Under SP 14544, each empty 
container must be pressure tested at 120 psig instead of the HMR 
requirement that each empty container must be subjected to a pressure 
equal to or in excess of the maximum expected in the filled containers 
at 55 [deg]C (131 [deg]F), and that is at least two-thirds of the 
design pressure of the container. Under both tests, if there is 
evidence of leakage, the container must be rejected. In this final 
rule, we are adopting the provisions of the SP as proposed to authorize 
the use of a leakage test as a means to determine compliance with 
pressure requirements. Our implementation differs from the SP in that 
we are adopting the leakage testing requirements under Sec.  
173.306(a)(5)(v), but including the SP 14544 testing protocol for empty 
containers as an alternative.
Accumulators
    The HMR provide special considerations for compressed gases in 
accumulators. SP 8786 authorizes the transport of accumulators under an 
alternative testing procedure than what is prescribed in paragraphs 
(f)(2) and (f)(3) of this section. Rather than testing each accumulator 
to three times (3x) the charge pressure, the SP provides for conditions 
to test one accumulator out of each lot of 1,000 to the burst design 
pressure, and two accumulators to two and a half times (2.5x) the 
charge pressure. In the NPRM, we proposed to adopt most of SP 8786 into 
Sec.  173.306. Because we did not receive public comment on this 
amendment, supportive or otherwise, it is adopted as proposed in the 
NPRM.
Aerosol Disposal
    The general packaging requirements of the HMR forbid the transport 
of leaking or improperly-filled packages. This includes aerosol 
containers that are found to be leaking or improperly filled as part of 
a combination packaging. SP 11296 provides an option to transport these 
containers to an offsite facility for disposal under certain conditions 
(e.g., overpacking in DOT specification packagings, modal restrictions, 
etc.). In the NPRM, we proposed to adopt the general scope of SP 11296 
with some differences. We proposed to also permit non-flammable 
aerosols. Further, the proposed regulatory language was modeled after 
the salvage packaging requirements of Sec.  173.3(c) in that: (1) The 
authorized outer packaging for overpacking the defective cylinders has 
been expanded to include other metal drums (i.e., 1B2 and 1N2); (2) a 
condition for cushioning and absorbent material, when necessary, has 
been added; and (3) an ``aerosol salvage'' drum marking has been 
adopted. Commenters were very supportive of our proposals to adopt such 
provisions for aerosol disposal and, in this final rule, we are 
codifying them as proposed.
Part 178
Section 178.33c
    Under the HMR, certain DOT specification containers with restricted 
capacity and commonly referred to as ``aerosol containers'' are 
authorized for the transportation of compressed and liquefied 
compressed gases under certain scenarios. These containers include DOT 
2P (inner non-refillable metal) containers. The specification standards 
are prescribed in Sec.  178.33 of the HMR and do not provide for 
variations of those standards. Thus, technological advances or design 
modifications to satisfy customer needs are such that the resulting 
metal containers would not conform to the standards for a DOT 2P 
container, nor any other container authorized under Sec. Sec.  173.304 
or 173.306 of the HMR. SPs 13601 and 14503 (also 7951) provide for a 
variation of the DOT 2P container specifications by authorizing 
construction of the container according to modifications of the 
standards for manufacture and testing.
    The special permits authorized variations of a DOT 2P container 
that are equipped with some manner of pressure relief system (e.g., a 
rim-vent release device or a dome expansion device). The rim vent 
release devices must function within a certain pressure range, 
otherwise the container is rejected. The dome expansion devices are 
designed to buckle to relieve pressure before bursting. For example, 
for a container built to SP 13601, the pressure relief system must 
function between 175 psig and 210 psig or be rejected.
    In the NPRM, we stated that we have no specific information in the 
SP(s) on the relationship between the functional range and the tested 
burst pressure. The current minimum burst pressure for a DOT 2P 
container is 240 psig (Sec.  178.33-8). Using the SP 13601 construction 
requirements, the minimum burst pressure is indicated as 270 psig 
(assumed at 130 [deg]F) and pressure of the contents at 130 [deg]F may 
not exceed 160 psig thus, equating to approximately 1.7x the contents 
at 130 [deg]F without bursting (which is more stringent than for a DOT 
2P under the HMR). Thus, the upper pressure range of the relief system 
is 77.8% of the design burst pressure of 270 psig.
    This is further complicated under SP 14503 (and 7951) where the 
standard for the pressure of the contents is set at 23.9 [deg]C (75 
[deg]F) for which we do not have an equivalent requirement under the 
HMR. Additionally, the ranges for functioning of the relief systems 
have a higher upper bound, 175 psig to 250 psig and 175 psig to 235 
psig, respectively. Lastly, there is no minimum burst pressure 
specified in SP 14503 (and 7951); therefore, we must default to the DOT 
2P minimum burst pressure of 240 psig. Again, the circumstances are 
unclear in that the upper bounds for the functional ranges approach or 
exceed the DOT 2P minimum burst pressure yet we do not have information 
on the actual tested burst pressure which could be much larger. 
Therefore, based on the requirements of SP 13601, we proposed to 
implement a requirement that for containers with pressure relief 
systems, the upper bound of the functional range for a pressure relief 
system must be no greater than 85% of the minimum burst pressure. In 
the NPRM, we proposed to incorporate the standards for the modified DOT 
2P container described in SP 13601 (and likely 14503 (7951)) as a 
variation of the DOT 2P container design. As adopted in this final 
rule, the variation is required to be marked as a ``DOT 2P1.'' All 
standards for a DOT 2P1 remain the same as those for a DOT 2P except 
for the variations prescribed in new Sec.  178.33c-2.
    Commenters expressed concerns about imposing pressure limits on the 
range of the pressure relief systems although there are various 
pressure limits in each special permit that incorporates a rim vent 
release type of device in the container design. The commenters state 
that the actual activation range of the pressure relief system design 
is not as important to safety as that the system must function before 
the container bursts. We agree with the commenters. In the testing 
requirement of DOT 2P1, the performance standard is that the containers 
must fail at the location of the pressure relief system or the lot will 
be rejected. PHMSA believes that incorporating the DOT 2P1 without a

[[Page 3656]]

specific functional range or limit for a rim vent release system will 
make the container specification more suitable for incorporation into 
the HMR because of broader applications rather than prescriptive 
regulatory text based on specific special permits. In this final rule, 
PHMSA will incorporate the requirements for the end expansion devices 
as proposed. The containers with an end expansion device must buckle 
prior to burst.
Section 178.33d
    Under the HMR, certain DOT specification containers with restricted 
capacity and commonly referred to as ``aerosol containers'' are 
authorized for the transportation of compressed and liquefied 
compressed gases under certain scenarios. These containers include DOT 
2Q (inner non-refillable metal) containers. Though the DOT 2Q 
specification is prescribed in Sec.  178.33a of the HMR, it does not 
provide for variations of those standards. Thus, technological advances 
or design changes to satisfy customer needs are such that the resulting 
metal containers would not conform to the standards of a DOT 2Q 
container, nor any other container authorized under either Sec. Sec.  
173.304 or 173.306 of the HMR. SP 12573 provides for a variation of the 
DOT 2Q container specifications by authorizing construction of the 
container according to modifications to the standards for type and 
size, manufacture, wall thickness, and testing. SP 14503 also provides 
for a variation of the DOT 2Q container specification by authorizing 
construction of the container according to modifications to its 
manufacture and testing criteria.
    Variations provided in the SPs for DOT 2Q containers require that 
they are equipped with some type of pressure relief system (e.g., a 
rim-vent release device or a dome expansion device), that must function 
by a certain threshold level or within a certain pressure range, 
otherwise the container is rejected. In effect, these containers are 
designed to buckle to relieve pressure before bursting. For example, 
for a container built to SP 12573, the minimum pressure before the 
system buckles is 220 psig (and if not equipped with a pressure relief 
system, the container may not burst below 320 psig). The maximum 
pressure of the contents authorized under this SP is 198 psig at 54.4 
[deg]C (130 [deg]F) (in the NPRM, we proposed a maximum pressure of 200 
psig based on this SP in the Sec.  173.306 discussion for DOT 2Q 
containers). After reviewing comments to the NPRM, we will adopt a 
maximum pressure of 210 psig at 55 [deg]C (131 [deg]F) in this final 
rule. The current requirements for a DOT 2Q container under Sec.  
173.306(a)(3)(ii) is that the pressure of the contents cannot exceed 
180 psig at 54.4 [deg]C (130 [deg]F) and the container must be capable 
of withstanding a pressure of 1.5x the contents at 54.4 [deg]C (130 
[deg]F) without bursting. Applying the same multiplier to 210 psig, the 
container must withstand at least 305 psig without bursting. The SP 
12573 minimum burst pressure of 320 psig is more than the current 
required minimum burst pressure of 270 psig for a DOT 2Q container; 
however, it provides approximately the same safety factor of 1.52. In 
this final rule, we are adopting as proposed the standards for the 
modified DOT 2Q container found in SP 12573 as a variation of the DOT 
2Q container design. This variation is required to be marked ``DOT 
2Q1.''
    The requirements under SP 14503 operate differently in that the 
standard for the pressure of the contents is set at 23.9 [deg]C (75 
[deg]F) to which we do not have an equivalent requirement under the 
HMR. Additionally, the SP provides for a range of pressure for 
functioning of the relief systems, specifically, 180 to 300 psig. 
Lastly, there is no minimum burst pressure specified in SP 14503 so we 
must default to the DOT 2Q minimum burst pressure of 270 psig. The 
upper bound for the functional range exceeds the 2Q minimum burst 
pressure yet we do not have information on the actual tested burst 
pressure which could be much larger. Therefore, based on a similar 
proposal to implement provisions of SP 13601 for 2P containers (see 
Sec.  178.33c preamble discussion), the upper bound of the functional 
range for a pressure relief system must be no greater than 80% of the 
test pressure. In the NPRM, we invited comment on using this approach 
and whether it would be preferable to implement a requirement for the 
upper bound of the range based on the pressure of the contents.
    Commenters did not respond specifically to the question of 
functional range for the DOT 2Q1 or 2Q2; however, they expressed 
concerns about imposing pressure limits on the range of the pressure 
relief systems of the DOT 2P1 which incorporates a similar pressure 
relief system design. The commenters state that the actual activation 
range of the pressure relief system design is not as important to 
safety as that the system must function before the container bursts. We 
agree with the commenter. We are imposing the same testing requirement 
as that for the DOT 2P1 in that the containers must fail at the 
location of the pressure relief system or the lot will be rejected. The 
containers with an end expansion device must buckle prior to burst.
    In this final rule, we are adopting as proposed the standards for 
the modified DOT 2Q container described in SP 14503 as a variation on 
the DOT 2Q container design. This variation is required to be marked as 
a ``DOT 2Q2.'' Further, the pressure relief device requirements for the 
DOT 2Q2 will be the same as that for the DOT 2P1 and 2Q1.

C. Cargo Tanks/Rail Cars/Portable Tanks

Part 173
Section 173.315
    Section 173.315 prescribes bulk packaging provisions for liquefied 
compressed gases in UN and DOT specification cargo tanks and portable 
tanks.
    SP 12576 authorizes non-DOT specification cargo tanks for the 
transportation of ``UN1080, Sulfur hexafluoride'' that otherwise 
conform to the MC 331 specifications except for design pressure, 
capacity, and marking. In the NPRM, we proposed to revise the Sec.  
173.315(a)(2) table by referring to a new note 28 in the entry for 
``Division 2.2, materials not specifically provided for in this table'' 
as Sulfur hexafluoride is not listed by name in the table. New note 28 
codifies such tanks specified in SP 12576 for the transportation of 
sulfur hexafluoride. Because we did not receive public comment on this 
amendment, supportive or otherwise, it is adopted as proposed in the 
NPRM.
Section 173.319
    Section 173.319 prescribes the loading and packaging provisions for 
cryogenic liquids transported in rail tank cars.
    SP 12039 authorizes the transportation in commerce of DOT 113C120W 
rail tank cars containing ``UN1038, Ethylene, refrigerated liquid,'' at 
an internal pressure of 20 psig instead of the maximum 10 psig. 
Currently, the HMR authorizes a maximum of 10 psig in a DOT 113C120W 
rail tank car containing cryogenic ethylene when offered for 
transportation by rail. Because we did not receive public comment on 
this amendment, supportive or otherwise, it is adopted as proposed in 
the NPRM.

D. Operational Air/Vessel

Part 176
Section 176.90
    Section 176.90 prescribes requirements for private automobiles

[[Page 3657]]

carrying Class 1 hazardous materials on board ferry vessels. There are 
four SPs that provide relief for ferry transport of private automobiles 
carrying engines, gasoline, and propane. SP 7465, 11150, 13213, and 
14458 all contain slightly different provisions to facilitate this 
process safely. Where differences exist between these permits, PHMSA 
has attempted to choose the least restrictive provision for adoption.
    In the NPRM, PHMSA proposed to renumber the existing paragraph in 
Sec.  176.90 as paragraph (a), and add a new paragraph (b) to adopt an 
exception for ``UN3166, Engines, internal combustion, flammable gas 
powered or flammable liquid powered, including when fitted in machinery 
or vehicles (i.e. motor vehicles, recreational vehicles, campers, 
trailers), vehicle flammable liquid or flammable gas powered, gasoline, 
and petroleum gases, liquefied or liquefied petroleum gas'' when 
included as part of a motor home, recreational vehicle, camper, or 
trailer and carried aboard ferry vessels subject to certain operational 
controls. Because we did not receive public comment on this amendment, 
supportive or otherwise, it is adopted as proposed in the NPRM.
Section 176.800
    Section 176.800 of the HMR prescribes general vessel stowage 
requirements for corrosive materials.
    SP 11691 authorizes transportation in commerce of certain flammable 
and corrosive liquids, which are the ingredients of soft drinks 
(beverages), not subject to the segregation requirements for vessel 
stowage when shipped in the same transport unit. In the NPRM, we 
proposed to add a new special provision, W11, to Sec.  172.102, 
regarding vessel segregation of corrosive and combustible materials and 
foodstuffs. Based on comments from PCSD, proposed Special provision W11 
is being replaced by revising paragraph (a) of Sec.  176.800 to allow 
Class 8 (corrosive) materials that are also foodstuffs or foodstuff 
ingredients intended for human consumption to not be considered 
incompatible for segregation purposes.

E. Operational Highway/Rail/Shipper/Other

Part 171
Section 171.8
    Section 171.8 defines terms generally used throughout the HMR that 
have broad or multi-modal applicability.
    In the NPRM, PHMSA proposed to add the following definition based 
on the adoption of SP 11458:
    Display pack means a package intended to be placed at retail 
locations which provide direct customer access to consumer commodities 
contained within the package when all or part of the outer fiberboard 
packaging is removed.
    SP 11458 authorizes the transportation in commerce of display packs 
of consumer commodity packages or limited quantity packages that exceed 
the 30 kg gross weight limit. The provisions of SP 11458 were proposed 
for adoption into Sec.  173.156. However, the term ``display pack'' is 
not currently defined in the HMR. In the NPRM we proposed to adopt the 
definition of ``display pack'' in Sec.  171.8 based upon its definition 
in SP 11458. Commenters were very supportive of our proposal to adopt a 
definition of display packs in Sec.  171.8 and, in this final rule, we 
are codifying it as proposed.
Part 172
Sections 172.101 (Hazardous Materials Table) and 172.102 Special 
Provisions
    Section 172.101 provides instructions for using the Hazardous 
Materials Table (HMT) and the HMT itself. Column 7 of the HMT provides 
codes for special provisions applicable to specific hazardous materials 
descriptions. Special provisions may contain unique packaging 
requirements, prohibitions, and exceptions applicable to particular 
quantities or forms of hazardous materials. When Column 7 of the HMT 
refers to a special provision, the requirements of that special 
provision are as set forth in Sec.  172.102. In the NPRM, PHMSA 
proposed the following revisions to Sec.  172.102:
Special Provision 380
    SP 10705 provides relief from the segregation requirements of Sec.  
177.848(d) for the transport of ``UN1092, Acrolein, stabilized,'' by 
private carrier in a motor vehicle. In the NPRM, PHMSA proposed to add 
Special Provision 380 to Sec.  172.102(c)(1) to codify SP 10705. The SP 
prescribes the packaging that must be used and the materials in which 
it may be loaded. Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendment as proposed.
Special Provision 381
    SP 7991 provides relief from the HMR for the transportation of 
railroad flagging kits by highway. See Sec.  173.184 for a detailed 
discussion of the adoption of SP 7991. In the NPRM, PHMSA proposed to 
add Special Provision 381 to Sec.  172.102(c)(1) to codify SP 7991. As 
adopted in this final rule, Special Provision 381 will be assigned to 
the following HMT entries: Fusee (rail or highway) (NA1325, Division 
4.1, PG II); Articles, pyrotechnic (UN0431, Division 1.4G, PG II); 
Signal Devices, hand (UN0373, Division 1.4S, PG II); Signal Devices, 
hand (UN0191, Division 1.4G, PG II); and Signals, railway track, 
explosive (UN0193, Division 1.4S, PG II). Because we did not receive 
public comment on the proposal, adverse or otherwise, in this final 
rule, we are adopting the amendment as proposed.
Special Provision 382
    SP 8006 provides relief from the labeling requirements of Sec.  
172.400(a) for the transportation of toy plastic or paper caps for toy 
pistols by motor vehicle, railcar, cargo vessel, and cargo aircraft. 
See Sec.  172.400a(a)(8) for a detailed discussion of the adoption of 
SP 8006. In the NPRM, PHMSA proposed to add Special Provision 382 to 
Sec.  172.102(c)(1) to codify SP 8006. Special Provision 382 will be 
assigned to the following HMT entries: Articles, explosive, n.o.s. 
(UN0349) and Toy caps (NA0337). Because we did not receive public 
comment on the proposal, adverse or otherwise, in this final rule, we 
are adopting the amendment as proposed.
Special Provision 383
    SP 11356 authorizes material meeting the conditions for high 
viscosity flammable liquids specified in Sec.  173.121(b)(1)(i), 
(b)(1)(ii), and (b)(1)(iv), to be re-classed to Packing Group III for 
transportation by motor vehicle. In the NPRM, PHMSA proposed to add 
Special Provision 383 to Sec.  172.102(c)(1) to codify SP 11356. The SP 
prescribes packaging, capacity limitations, and load securement 
requirements. Special Provision 383 will be assigned to the following 
HMT entries: Coating solution (UN1139, PG II) and Paint (and Paint 
related material) (UN1263, PG II). Because we did not receive public 
comment on the proposal, adverse or otherwise, in this final rule, we 
are adopting the amendment as proposed.
Special Provision 384
    SP 11666 authorizes the transportation of green graphite electrodes 
and shapes that are large single component solid objects not subject to 
sifting, in open rail flat cars, open bed motor vehicles, and 
intermodal containers. In the NPRM, PHMSA proposed to add Special 
Provision 384 to Sec.  172.102(c)(1) to codify SP 11666. The SP 
prescribes load securement requirements for the electrodes and shapes. 
Further, the SP permits stacking two or more levels high

[[Page 3658]]

to achieve maximum allowable utilization of the designated vehicle, 
rail car weight, or intermodal freight container weight or vessel hold 
volume. Special Provision 384 will be assigned to the following HMT 
entries: Other regulated substances, n.o.s. (NA3077, PG III) and 
Environmentally hazardous substances, solid, n.o.s. (UN3077, PG III). 
In this final rule, we are adopting the amendments as proposed with 
minor editorial clarifications.
Special Provision 385
    SP 13343 authorizes the use of cargo heaters when weather 
conditions are such that the freezing of certain wetted explosive 
material is likely. In the NPRM, PHMSA proposed to add Special 
Provision 385 to Sec.  172.102(c)(1) to codify SP 13343. Transportation 
must be performed by private, leased or contract carrier vehicles in 
exclusive use. Further, cargo heaters must be reverse refrigeration 
(heat pump) units. Shipments made in accordance with the SP are 
excepted from the anti-freeze requirements of Sec.  173.60(b)(4). The 
provisions of SP 13343 are specific to ``UN0394, Trinitroresorcinol, 
wetted or Styphnic acid, wetted with not less than 20% water, or 
mixture of alcohol and water by mass''; therefore, Special Provision 
385 will be assigned exclusively to those HMT entries. Because we did 
not receive public comment on the proposal, adverse or otherwise, in 
this final rule, we are adopting the amendment as proposed.
Special Provision 386
    In the NPRM, we proposed to codify SP 6614 by establishing a new 
paragraph (b)(3) to authorize polyethylene bottles with rated 
capacities of one gallon (3.785 liters), packed inside an open-top, 
heavy wall, high density polyethylene box for shipping certain PG II 
and III corrosive liquids by private motor carrier. In this final rule, 
we are adopting SP 6614 as proposed; however, we are moving the 
amendment from paragraph (b) to new Sec.  172.102(c)(1), Special 
provision 386, as it is a more appropriate location in the HMR for it.
Special Provision B130
    SP 14525 provides relief from the HMR except for the shipping paper 
requirements of Subpart C of Part 172, emergency response information 
as required by Sec.  172.602, and the marking requirements of Sec.  
172.302(a), (b), and (d) when transporting used diatomaceous earth 
filter material by highway. In the NPRM, PHMSA proposed to add Special 
Provision B130 to Sec.  172.102(c)(3) to codify SP 14525. The SP 
prescribes packaging, quantity limitations, and the required method of 
storing the packages within the motor vehicle. The provisions of SP 
14525 are specific to ``UN3088, Self-heating solid, organic, n.o.s'' 
(PG III); therefore, Special Provision B130 will be assigned 
exclusively to that HMT entry. Because we received minimal public 
comment on the proposal, in this final rule, we are adopting the 
amendment as proposed.
Special Provision B131
    As previously discussed, SP 11624 was not proposed for adoption in 
the NPRM. The SP is in its fifteenth revision and has 114 grantees. The 
SP authorizes transportation in commerce of certain waste Class 3 paint 
and paint related material (UN1263; PG II and PG III) contained in 
metal or plastic pails further packed in non-specification bulk 
packagings such as cubic yard boxes, plastic rigid-wall bulk 
containers, dump trailers, and roll-off containers. After careful 
reevaluation, SP 11624 and three related packaging SPs (i.e., SP 13052, 
SP 14712, and 15235) are adopted as new Sec.  172.102(c)(3), Special 
Provision B131.
Special Provision B132
    SP 11602 authorizes the transportation in commerce of certain 
Division 4.3 materials contained in sift-proof closed bulk packagings 
that prevent water from reaching the hazmat and have sufficient venting 
to preclude a dangerous accumulation of gaseous emissions. In the NPRM, 
we proposed to adopt the provisions of SP 11602 in its entirety in 
Sec.  173.151(g). Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendment as proposed. However, in this final rule, we are moving the 
amendment to new Sec.  172.102(c)(3), Special provision B132 as it is a 
more appropriate section for these provisions.
Section 172.202
    Section 172.202 prescribes requirements for describing hazardous 
materials on shipping papers. In many scenarios, a net or gross 
quantity of the hazardous materials must be included.
    SP 11811 provides relief from this requirement for local 
collections operations transporting hazardous materials and hazardous 
substances by highway that are ``household wastes'' as defined in 40 
CFR 261.4 and not subject to the Environmental Protection Agency's 
hazardous waste regulations in 40 CFR, Parts 262 and 263. In the NPRM, 
we proposed to revise paragraph (c) of Sec.  172.202 to adopt the 
provisions of SP 11811 in its entirety. Because we did not receive 
public comment on the proposal, adverse or otherwise, in this final 
rule, we are adopting the amendment as proposed.
Section 172.315
    Section 172.315 prescribes marking requirements for packages of 
limited quantities of hazardous materials.
    SP 11197 provides relief from the requirement to display the 
limited quantity marking on packages containing certain low-risk 
materials assigned to PG II and III prepared in accordance with the 
limited quantity provisions in Subpart B of part 173 of the HMR for 
highway transportation by private motor carrier. The SP prescribes 
inner packaging and package quantity limitations; the maximum gross 
weight of packages that may be transported in one vehicle; and special 
package marking requirements. In the NPRM, we proposed to add a new 
paragraph (a)(3) to Sec.  172.315 to adopt the provisions of SP 11197 
in its entirety. Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendment as proposed.
Section 172.400a
    Section 172.400a provides exceptions from the Sec.  172.400 general 
labeling requirements for packages or containment devices of hazardous 
materials.
    SP 8006 provides relief from the Sec.  172.400 general labeling 
requirements for toy plastic or paper caps for toy pistols described as 
``UN0349, Articles, explosive, n.o.s. (Toy caps), 1.4S'' or ``NA0337, 
Toy caps, 1.4S'' when offered for transportation by motor vehicle, rail 
freight, cargo vessel, and cargo aircraft. The toy plastic or paper 
caps must have been examined in conformance with Sec.  173.56 and 
approved by the Associate Administrator. In the NPRM, we proposed to 
add a new paragraph (a)(8) to Sec.  172.400a to adopt the provisions of 
SP 8006 in its entirety. Because we did not receive public comment on 
the proposal, adverse or otherwise, in this final rule, we are adopting 
the amendment as proposed.
Part 173
Section 173.12
    Section 173.12 provides certain exceptions and authorizations for 
the transportation of waste hazardous materials.
    SP 11470 authorizes transportation by motor vehicle and cargo 
vessel of shrink-wrapped pallets containing boxes of waste ORM-D or 
limited quantity materials when marked with the word ``WASTE'' on the 
outside of

[[Page 3659]]

the pallet instead of each individual box. The SP also prescribes 
packaging requirements for the waste materials. COSTHA requested that 
PHMSA adopt this SP into the HMR under petition for rulemaking P-1611. 
In the NPRM, we proposed to add a new paragraph (h) to Sec.  173.12 to 
adopt the provisions of SP 11470 in its entirety. Because of the 
supportive public comments received as a result of our proposal, in 
this final rule, we are adopting the amendments as revised. Based on 
comments from Veolia, the revisions include authorizing ``stretch-
wrapped'' pallets in addition to shrink-wrapped pallets and 
``packages'' rather than boxes only.
Section 173.29
    Section 173.29 prescribes certain requirements, exceptions, and 
authorizations for the transportation of empty packagings.
    SP 9610 provides relief from shipping paper and placarding 
requirements of Subparts C and F of part 172, respectively, for 
smokeless powder residue when transported by motor vehicle or railcar 
in ``Container-on-flat-car'' (COFC) or ``Trailer-on-flat-car'' (TOFC) 
service. The smokeless powder must be approved in conformance with 
Sec.  173.56 as a Class 1 explosive substance. The SP prescribes 
packaging requirements, quantity limitations, operational controls, and 
a specific shipping description for the material. In the NPRM, we 
proposed to revise paragraph (f) of Sec.  173.29 to adopt the 
provisions of SP 9610 in its entirety. Because of the supportive public 
comments received as a result of our proposal, in this final rule, we 
are adopting the amendments as proposed with minor revisions to allow 
additional packaging types.
Section 173.63
    Section 173.63 provides packaging exceptions for certain Class 1 
(explosive) materials.
    SP 4850 authorizes Cord, detonating, or Fuse detonating, metal clad 
(UN0290, Div. 1.1D) to be renamed and reclassed as Cord, detonating, 
mild effect, or Fuse, detonating, mild effect, metal clad (UN0104, Div. 
1.4D); and Charges, shaped, flexible, linear (UN0288, Div. 1.1D) to be 
renamed and reclassed Charges, shaped, flexible, linear (UN0237, Div. 
1.4D) and transported by motor vehicle, railcar, cargo vessel, and 
cargo aircraft. The SP prescribes packaging requirements and quantity 
limitations. In the NPRM, we proposed to revise paragraph (a) of Sec.  
173.63 to adopt the provisions of SP 4850 in its entirety. However, 
during review of the final rule, concerns that there was insufficient 
hazard communication to prevent the reclassed shipments from finding 
their way into the air mode were raised. In addition, concerns 
regarding the distinctions between shipping being offered domestically 
versus internationally were discussed. Because additional conditions 
for its adoption were not proposed in the January 30, 2015 NPRM, in 
this final rule, we are not codifying SP 4850 into the HMR at this time 
but intend to consider it for incorporation in the near future 
considering the hazard communication concerns. We will include any 
proposals in upcoming NPRMs for comment.
Section 173.156
    Section 173.156 provides exceptions for the transportation of 
certain limited quantities and other regulated materials (ORM).
    SP 11458 authorizes display packs of consumer commodity packages 
that exceed 30 kg gross weight for transportation by railcar in 
trailer-on-flat-car (TOFC) or container-on-flat-car (COFC) service, or 
roadrailer and/or railrunner trailers or by motor vehicle, or cargo 
vessel. See Sec.  171.8 for a discussion of the addition of the 
definition of display pack. In a petition for rulemaking (P-1607), 
COSTHA requested PHMSA adopt this SP into the HMR. In the NPRM, we 
proposed to add a new paragraph (c) to Sec.  173.156 to adopt the 
provisions of SP 11458 in its entirety. Because of the supportive 
public comments received as a result of our proposal, in this final 
rule, we are adopting the amendment as proposed.
    SP 11470 authorizes transportation by motor vehicle and cargo 
vessel of shrink-wrapped pallets containing boxes of waste ORM-D or 
limited quantity materials when marked with the word ``WASTE'' on the 
outside of the pallet instead of each individual box. The adoption of 
SP 11470 relating to exceptions for waste limited quantity and ORM-D 
materials is discussed in the preamble for Sec.  173.12. In the NPRM, 
we proposed to add a new paragraph (d) to Sec.  173.156 that directs 
the reader to the new paragraph (h) of Sec.  173.12 which codifies the 
provisions of SP 11470. Because of the supportive public comments 
received as a result of our proposal, in this final rule, we are 
adopting the amendment as proposed with one modification. Veolia 
supports adoption of SP 11470 with one substantial modification--the 
HMR should not limit to ``expired'' consumer products but rather all 
consumer commodities shipped for disposal/recycling under manufacturer 
recalls, off-spec/unwanted/unneeded product, etc. We recognized the 
merit of Veolia's comment and revised Sec.  173.12 accordingly.
Section 173.159
    Section 173.159 prescribes requirements for the transportation of 
wet electric storage batteries.
    SP 11078 conditionally excepts the transportation of nickel cadmium 
batteries containing potassium hydroxide, a Class 8 material, from 
other requirements of the HMR when transported by motor vehicle, 
railcar, cargo vessel and passenger and cargo aircraft. In the NPRM, we 
proposed to add a new paragraph (j) to Sec.  173.159 to codify the 
provisions of SP 11078 in its entirety. Because we did not receive 
public comment on the proposal, adverse or otherwise, in this final 
rule, we are adopting the amendment as proposed.
    SP 13548 authorizes transportation in commerce of lead acid 
batteries and packages of battery acid (with two different 
identification numbers) on the same vehicle. Commenters were supportive 
of its adoption in the HMR. In this final rule, the introductory text 
in paragraph (e) is revised accordingly.
Section 173.168
    Section 173.168 prescribes specific approval, testing, protection, 
packaging, and equipment marking requirements for chemical oxygen 
generators.
    SP 11984 authorizes certain unapproved chemical oxygen generators 
with only one positive means of preventing unintentional actuation of 
the generator, and without the required approval number marked on the 
outside of the package, to be transported by motor vehicle, railcar, 
and cargo vessel. In the NPRM, we proposed to add a new paragraph (g) 
to Sec.  173.168 to adopt the provisions of SP 11984 in its entirety. 
Veolia supports adoption of SP 11984 with one modification--the HMR 
should require flame-proof outer packaging for chemical oxygen 
generators shipped with only one positive means of preventing 
unintentional activation as expressed in concern for equivalent level 
of safety in proposed SP modification in August 2011. Veolia's comments 
notwithstanding, because of the mainly supportive public comment 
received and safety evaluation as a result of our proposal, in this 
final rule, we are adopting the amendment as proposed.
Section 173.184
    Section 173.184 prescribes packaging requirements for the 
transportation of highway or rail fusees.

[[Page 3660]]

    When in conformance with SP 7991, flagging kits transported on 
railroad motor vehicles including privately-owned motor vehicles under 
the direct control of on-duty railroad employees, are excepted from the 
requirements of the HMR. Flagging kits may only contain fusees and 
railroad torpedoes described as: Fusee (rail or highway) (NA1325, 
Division 4.1, PG II); Articles, pyrotechnic (UN0431, Division 1.4G, PG 
II); Signal devices, hand (UN0373, Division 1.4S, PG II); Signal 
devices, hand (UN0191, Division 1.4G, PG II); and Signals, railway 
track, explosive (UN0193, Division 1.4S, PG II). This SP prescribes 
packaging requirements, quantity limitations, and operational controls. 
In the NPRM, we proposed to add a new paragraph (c) to Sec.  173.184 to 
adopt the provisions of SP 7991 in its entirety. Because we did not 
receive public comment on the proposal, adverse or otherwise, in this 
final rule, we are adopting the amendment as proposed.
Section 173.226
    Section 173.226 prescribes specific packaging requirements for the 
transportation of materials poisonous by inhalation, Division 6.1, PG 
I, Hazard Zone A.
    When transported as prescribed in SP 11055, liquid hazardous 
materials in Division 6.1, PG I, Hazard Zone A, are excepted from the 
segregation requirements of Sec. Sec.  174.81, 176.83, and 177.848(d). 
The SP prescribes packaging and testing requirements, quantity 
limitations, and cushioning and absorbent material requirements. In the 
NPRM, we proposed to add a new paragraph (f) to Sec.  173.226 to adopt 
the provisions of SP 11055 in its entirety. Because we did not receive 
public comment on the proposal, adverse or otherwise, in this final 
rule, we are adopting the amendment as proposed.
Section 173.306
    Section 173.306 provides exceptions for limited quantities of 
compressed gas. Section 173.306(e) currently permits only new (unused) 
refrigerating machines to be excepted from specification packaging, 
placarding, and certain rail and highway modal requirements.
    SP 13199 permits reconditioned (used) refrigerating machines 
(UN2857, Div. 2.2) to be transported under the requirements prescribed 
in Sec.  173.306(e) and excepted from the marking requirements of Sec.  
172.302(c) when transported by motor vehicle and meeting certain 
structure and Class A refrigerant gas weight requirements. In the NPRM, 
we proposed to add new paragraph (e)(2) to Sec.  173.306 to adopt the 
provisions of SP 13199 in its entirety. Because we did not receive 
public comment on the proposal, adverse or otherwise, in this final 
rule, we are adopting the amendment as proposed.
Section 173.322
    Section 173.322 prescribes packaging requirements for ethyl 
chloride. In the January 30, 2015 NPRM, we proposed to add a new 
paragraph (f) to Sec.  173.322 to adopt the provisions of SP 14422 in 
its entirety. Because SP 14422 is no longer an active special permit, 
in this final rule, we are not adopting the amendment as proposed.
Part 174
Section 174.67
    Section 174.67 prescribes operational requirements for the railroad 
tank car unloading of hazardous materials.
    SP 12002 authorizes the clearing of frozen liquid blockages from 
tank car outlets by attaching a fitting to the outlet line and applying 
nitrogen at a pressure of 50 to 100 psi for combustible liquid or Class 
3 liquid petroleum distillate fuels. In the NPRM, we proposed to revise 
paragraph (g) to Sec.  174.67 to adopt the provisions of SP 12002 in 
its entirety. In its comments, ACA recommends that the use of nitrogen 
should be permitted ``at a pressure of up to 100 psi'' for clarity. We 
agree and revise Sec.  174.67(g) accordingly.
Part 177
Section 177.820
    Currently there is no Sec.  177.820 in the HMR. However, in the 
NPRM, we proposed to add a new Sec.  177.820 that authorizes the 
movement of certain hazardous materials across public roads with 
limited exceptions.
    SPs 11352, 12207, 12306, 13165, and 14945 authorize the movement of 
certain hazardous materials across public roads. Such movements are not 
subject to Subparts C (Shipping Papers), D (Marking), E (Labeling), and 
F (Placarding) of Part 172. The SPs prescribe specific operational 
controls. In the NPRM, we proposed to add a new Sec.  177.820 to adopt 
the provisions of these SPs in their entirety. COSTHA and DGAC support 
the adoption of SPs 11352, 12207, 12306, 13165, and 14945; however, 
according to COSTHA, the proposed regulatory text in Sec.  177.820 
appears to be more restrictive than the HMR applicability exceptions 
currently in Sec.  171.1(d)(4). We agree with COSTHA and are not 
adopting the five SPs and new Section 177.820 as proposed in the NPRM.
Section 177.834
    Section 177.834 establishes general operational requirements for 
hazardous materials transportation by highway.
    SPs 9874, 13190, 13424, 13959, 14141, 14150, 14680, 14822, 14827, 
and 14840 authorize ``attendance'' of the loading or unloading of a 
cargo tank by a qualified person observing all loading or unloading 
operations by means of video cameras and monitors or instrumentation 
and signaling systems such as sensors, alarms, and electronic 
surveillance equipment located at a remote control station. In the 
NPRM, we proposed to revise paragraphs (i)(3) and (i)(4) of Sec.  
177.834 to adopt the provisions of these SPs in their entirety.
    In its comments, Dow supports codification of the SPs but has 
specific concerns: (1) SP 9874 and 14822 authorize instrumentation and 
signaling systems such as sensors, alarms, and electronic surveillance 
equipment in addition to video monitoring; (2) SPs 9874 and 14822 do 
not require a video camera with a ``motorized zoom lens capable of 
panning and zooming from the remote control station''; (3) SPs 9874 and 
14822 do not require that the view capability must include the entire 
containment area; and (4) the need for assurance that the attendance 
requirements in Sec.  177.834 (i) apply to motor carriers only. We 
agree that Dow's comments have merit and, in this final rule, except 
for number (4), the regulatory text in Sec.  177.834(i) is revised 
accordingly. Regarding issue number (4), long-standing interpretations 
preclude the need to revise the attendance applicability provisions of 
the HMR.
    SPs 13484 and 14447 authorize ``attendance'' of the loading or 
unloading of a cargo tank through the use of hoses equipped with cable 
connected wedges, plungers, or flapper valves located at each end of 
the hose, able to stop the flow of product from both the source and the 
receiving tank within one second without human intervention in the 
event of a hose rupture, disconnection, or separation. The SPs 
prescribe inspection requirements and operational controls for use of 
the hoses. In the NPRM, we proposed to revise paragraphs (i)(3) and 
(i)(4) of Sec.  177.834 to adopt the provisions of SPs 13484 and 14447 
in their entirety. Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendments as proposed.
    SPs 10597, 10803, 10882, 14618, and 14726 authorize the use of 
diesel or propane fueled combustion cargo

[[Page 3661]]

heaters in motor vehicles used to transport Class 3 (flammable liquid) 
or Division 2.1 (flammable gas) materials. The SPs prescribe 
operational controls for use of heaters. In the NPRM, we proposed to 
revise paragraph (l)(2)(i) of Sec.  177.834 to adopt the provisions of 
these SPs in their entirety. In this final rule, because the existing 
paragraph (l)(2)(ii) of Sec.  177.834 relating to the Effective date 
for combustion heater requirements is obsolete, we are removing it as 
proposed. In addition, we are redesignating paragraph (l)(2)(iii) of 
Sec.  177.834 as paragraph (l)(2)(ii) as proposed in the NPRM. Because 
we did not receive public comment on the proposal, adverse or 
otherwise, in this final rule, we are adopting the amendment as 
proposed.
Section 177.838
    Section 177.838 prescribes operational requirements for the 
transportation of Class 4 (flammable solid) materials, Class 5 
(oxidizing) materials, and Division 4.2 (self-heating and pyrophoric 
liquid) materials.
    Notwithstanding the segregation requirements of Sec.  177.848(d), 
SP 11373 authorizes the transport on the same transport vehicle of 
``UN1384, Sodium hydrosulfite or sodium dithionite'' (PG II or III), 
``UN3341, Thiourea dioxide'' (PG II or III); and ``UN3088, Self-
heating, solid, organic, n.o.s.'' (PG II or III) with Class 8 
materials. The SP prescribes packaging and separation requirements. In 
the NPRM, we proposed to revise the title of Sec.  177.838 and add a 
new paragraph (i) to Sec.  177.838 to adopt the provisions of SP 11373 
in its entirety. Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendment as proposed.
Section 177.840
    Section 177.840 establishes specific operational requirements for 
the transportation of Class 2 (gases) materials.
    Notwithstanding the segregation requirements of Sec.  177.848(d), 
SP 11043 authorizes the transport on the same transport vehicle of 
Division 2.3, Hazard Zone A materials with materials classed as 
Division 2.1, Class 3, Class 4, Class 5, and Class 8. The SP prescribes 
packaging, marking, separation requirements.
    Notwithstanding the segregation requirements of Sec.  177.848(d), 
SP 14335 authorizes the transport on the same transport vehicle of 
Division 2.3, Hazard Zone A materials with specification non-bulk 
packagings and IBCs containing only the residue of Division 2.1, 4.3, 
5.1, and Class 3 and 8 materials. The SP prescribes separation and 
securement requirements, operational controls, quantity limitations, 
and carrier safety rating requirements.
    In the NPRM, we proposed to add a new paragraph (a)(3) to Sec.  
177.840 to adopt the provisions of SPs 11043 and 14335 in their 
entirety. Veolia supports the adoption of SP 11043; however, they 
recommend the regulatory text proposed in Sec.  177.840(a)(3)(i) should 
be revised to require a 4-foot separation rather than a 5-foot 
separation for consistency with the segregation spacing requirements in 
Sec.  173.12(e). We agree and are revising Sec.  177.840(a)(3)(i) 
accordingly.
Section 177.841
    Section 177.841 establishes specific operational requirements for 
the transportation of Division 6.1 and Division 2.3 materials.
    Notwithstanding the segregation requirements of Sec.  177.848(d), 
SP 11151 authorizes transportation by private or contract motor carrier 
of Division 6.1 PG I, Hazard Zone A materials meeting the definition of 
a hazardous waste as defined in Sec.  171.8 on the same transport 
vehicle with materials classed as Class 3, Class 4, Class 5, and Class 
8. The Division 6.1 PG I, Hazard Zone A materials must be loaded on 
pallets and separated from the Class 3, Class 4, Class 5, and Class 8 
materials by a minimum horizontal distance of 2.74 m (9 feet). In the 
NPRM, we proposed to add a new paragraph (f) to Sec.  177.841 to adopt 
the provisions of SP 11151 in its entirety. Because we did not receive 
public comment on the proposal, adverse or otherwise, in this final 
rule, we are adopting the amendment as proposed.

F. Non-Bulk Packaging Specifications/IBCs

Part 172
Section 172.101
    The Sec.  172.101 HMT designates the materials listed therein as 
hazardous materials for the purpose of transportation of those 
materials. For each listed material, the HMT identifies the hazard 
class or specifies that the material is forbidden in transportation, 
and provides the proper shipping name or directs the user to the 
preferred proper shipping name. In addition, the HMT specifies or 
references requirements in this subchapter pertaining to labeling, 
packaging, quantity limits aboard aircraft, and stowage of hazardous 
materials aboard vessels. In the NPRM, we proposed to revise several 
entries in the HMT to adopt SPs relating to non-bulk packagings and 
IBCs. Specifically, for ``UN1415, Lithium,'' ``UN2257, Potassium,'' 
``UN3190, Self-heating solid, inorganic, n.o.s.,'' ``UN1428, Sodium,'' 
``UN1381, Phosphorus, yellow, under water'' and ``UN2813, Water-
reactive solid, n.o.s.'' (Packing Group II and III), we proposed to add 
a reference to Sec.  173.151 to provide packaging exceptions for 
relevant Hazard Class 4 materials. In this final rule, the provisions 
adopted for ``UN1381, Phosphorus, yellow, under water'' and ``UN2813, 
Water-reactive solid, n.o.s.'' (Packing Group II and III) are moved to 
the more appropriate Sec. Sec.  173.188 and the new Sec.  
172.102(c)(3), Special provision B132 respectively. The revisions are 
discussed in the following sections.
Part 173
Section 173.62
    Section 173.62 prescribes packaging instructions for explosives.
    SP 12335 authorizes the transportation by motor vehicle, cargo 
vessel, and cargo aircraft when authorized in the HMT, and passenger-
carrying aircraft when authorized for carriage by the HMT and used 
exclusively to transport personnel to remote work sites certain 
Division 1.1D and 1.4D detonating cords without the ends being sealed 
in alternative packaging, provided that the inner packaging containing 
the detonating cord is made of a static-resistant plastic bag of at 
least 3 mil thickness and the bag is securely closed for 
transportation. In the NPRM, we proposed to adopt the provisions of SP 
12335 in its entirety in Sec.  173.62. Because we did not receive 
public comment on the proposal, adverse or otherwise, in this final 
rule, we are adopting the amendment as proposed.
Section 173.150
    Section 173.150 provides exceptions from the HMR for certain Class 
3 (flammable liquid) material.
    To codify SP 13217, in the NPRM, PHMSA proposed to add a paragraph 
(h) to Sec.  173.150 that included an exception to permit Diesel fuel 
(UN1202 or NA1993) and Gasoline (UN1203) to be transported one way, by 
motor vehicle, directly from the loading location to an equipment 
repair facility in non-specification non-bulk packaging, known as a 
gasoline dispenser. Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendment as proposed.
Section 173.151
    Section 173.151 provides exceptions for certain Class 4 materials.

[[Page 3662]]

    In the NPRM, we proposed to add new paragraph (e) that would except 
``UN1415, Lithium,'' ``UN2257, Potassium,'' and ``UN1428, Sodium,'' 
with a net quantity of material per inner packaging not exceeding 25 
grams, from the labeling requirements of Part 172, Subpart E and the 
placarding requirements of Part 172 Subpart F, if they are offered for 
transportation or are transported in the packagings with conditions set 
forth in that paragraph. We also proposed to codify SP 11736 by 
establishing a new paragraph (f) to authorize shipments of ``UN3190, 
Self-heating solid, inorganic, n.o.s,'' in unlined, non-DOT 
specification multi-wall paper bags containing a maximum of 55 pounds 
(net) weight. Because SP 11736 is no longer active, in this final rule, 
we are not amending Sec.  173.151 to codify the SP. We further proposed 
adding new paragraph (g) to authorize ``UN2813, Water reactive solid, 
n.o.s. (contains magnesium, magnesium nitrides)'' in PG II or III to be 
packaged in sift-proof bulk packagings. These revisions codify SPs 
11602, 11736, 13796, and 15373. Because we did not receive public 
comment on the proposals, adverse or otherwise, in this final rule, we 
are adopting the amendments as proposed.
    SP 11602 authorizes the transportation in commerce of certain 
Division 4.3 materials contained in sift-proof closed bulk packagings 
that prevent water from reaching the hazmat and have sufficient venting 
to preclude a dangerous accumulation of gaseous emissions. In the NPRM, 
we proposed to adopt the provisions of SP 11602 in its entirety in 
Sec.  173.151(g). Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendment as proposed. However, in this final rule, we are moving the 
amendment to new Sec.  172.102(c)(3), Special provision B132 as it is a 
more appropriate section for these provisions.
    SP 13796 authorizes the transportation in commerce of ``UN1381, 
Phosphorus, yellow, under water,'' in a 30 gallon UN 1A2 steel drum 
certified at a minimum to the PG I performance level for solids and the 
PG II performance level for liquids and, as a minimum, dual marked as 
UN1A2/X400/S (for solids) and UN1A2 Y/1.4/150 (for liquids). In the 
NPRM, we proposed to adopt the provisions of SP 13796 in its entirety 
in Sec.  173.151. Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendment as proposed. However, in this final rule, we are moving the 
amendment to the most appropriate section for yellow phosphorus, Sec.  
173.188; we are also removing the Sec.  173.151 column (8A) exception 
reference to its HMT entry.
    SP 15373 authorizes the manufacture, mark, sale and use of the 
specially designed combination packagings for ``UN1415, Lithium,'' 
``UN2257, Potassium,'' and ``UN1428, Sodium,'' without hazard labels or 
placards, for quantity limits not exceeding 25 grams. In the NPRM, we 
proposed to adopt the provisions of SP 15373 in its entirety in new 
Sec.  173.151(e). Because we did not receive public comment on the 
proposal, adverse or otherwise, in this final rule, we are adopting the 
amendment as proposed.
Section 173.154
    Section 173.154 provides exceptions for Class 8, (corrosive) 
materials.
    In the NPRM, we proposed to codify SP 6614 by establishing a new 
paragraph (b)(3) to authorize polyethylene bottles with rated 
capacities of one gallon (3.785 liters), packed inside an open-top, 
heavy wall, high density polyethylene box for shipping certain Packing 
Group II and III corrosive liquids by private motor carrier. In this 
final rule, we are adopting SP 6614 as proposed; however, we are moving 
the amendment from paragraph (b) to new Sec.  172.102(c)(1), Special 
provision 386, as it is a more appropriate location in the HMR.
    In the NPRM, we also proposed to codify SP 14137 in new paragraph 
(e) to authorize hydrochloric acid concentration not exceeding 38%, in 
Packing Group II, to be packaged in UN31H1 or UN31HH1 intermediate bulk 
containers when loaded in accordance with the requirements of Sec.  
173.35(h). In this final rule, we are adopting SP 14137 as proposed; 
however, we are moving the amendment from Sec.  173.154(e) to new Sec.  
172.102(c)(3), Special provision B133, as it is a more appropriate 
location in the HMR.
    These amendments to Sec.  173.154 codify SP 6614 and 14137. Because 
we did not receive public comment on the proposals, adverse or 
otherwise, in this final rule, we are adopting the amendments as 
proposed. However, the proposed provisions of SP 12030 are now codified 
in Sec.  173.159(h)(2), as it is a more appropriate location in the HMR 
for battery fluid packaging provisions.
Section 173.158
    Section 173.158 prescribes the general requirements, authorized 
packagings, and exceptions for nitric acid.
    To codify SPs 8230, 9722, and 14213, we proposed in the NPRM to 
establish a new paragraph (i) to authorize ``Nitric acid of up to 40% 
concentration'' in a UN1H1 non-removable head plastic drum with certain 
conditions set forth in that paragraph and add new paragraph (j) for 
the transportation of ``Nitric acid, other than red fuming, with more 
than 70% nitric acid'' and ``Nitric acid, other than red fuming, with 
not more than 70% nitric acid'' in a combination packaging when offered 
for transportation by rail, highway, or cargo vessel. Because of the 
supportive public comments received as a result of our proposal, in 
this final rule, we are adopting the amendments as proposed.
Section 173.159
    Section 173.159 prescribes packaging, shipping specifications, and 
exceptions for the transportation of wet electric storage batteries.
    To codify SP 13548, in the NPRM, we proposed to revise paragraph 
(e) to include shipments of electric storage batteries containing 
electrolyte or corrosive battery fluid, and electric storage batteries 
and battery acid. SP 13548 authorizes the transportation in commerce of 
lead acid batteries and packages of battery acid with two different UN 
numbers on the same motor vehicle with the packages secured against 
shifting. Because of the supportive public comments received as a 
result of our proposal, in this final rule, we are adopting the 
amendments as proposed.
    In the NPRM, we proposed to revise Sec.  173.154 by codifying SP 
12030 in new paragraph (f). After comment review and our own analysis, 
we believe this amendment is more appropriately codified in new Sec.  
173.159(h)(2) along with the existing provision in new Sec.  
173.159(h)(1). Special provision N6 of Sec.  172.102 specifies that 
battery fluid, acid or alkali, when packaged with an electric storage 
battery, wet or dry, is to be packaged as prescribed in Sec.  
173.159(g) or (h). Thus, in this final rule, we are moving the 
amendment from Sec.  173.154(f) to Sec.  173.159(h)(2) and codifying it 
as proposed.
Section 173.181
    Section 173.181 sets forth packaging and other requirements for 
pyrophoric materials (liquids).
    To codify SP 12920, in the NPRM, we proposed to add new paragraph 
(d) to Sec.  173.181 that authorizes the transportation of certain 
pyrophoric materials in a combination package consisting of UN1A2 outer 
package and a UN1A1 inner package. Because we did not receive public 
comment on the proposal, adverse or otherwise, in this final rule, we 
are adopting the amendment as proposed.

[[Page 3663]]

Section 173.188
    Section 173.188 prescribes the packaging instructions for white and 
yellow phosphorus.
    SP 13796 authorizes the transportation of ``UN1381, Phosphorus, 
yellow, under water,'' in a 30 gallon UN 1A2 steel drum certified as a 
minimum to the PG I performance level for solids and the PG II 
performance level for liquids and, as a minimum, dual marked as UN1A2/
X400/S (for solids) and UN1A2 Y/1.4/150 (for liquids). In the NPRM, we 
proposed to adopt the provisions of SP 13796 in its entirety in Sec.  
173.151. Because we did not receive public comment on the proposal, 
adverse or otherwise, in this final rule, we are adopting the amendment 
as proposed. However, in this final rule, we are moving the amendment 
to the most appropriate section for yellow phosphorus, Sec.  173.188; 
we are also removing the Sec.  173.151 column (8A) exception reference 
to its HMT entry.

VI. Regulatory Analyses and Notices

A. Statutory/Legal Authority for This Rulemaking

    This rulemaking is issued under the authority of the Federal 
hazardous materials transportation law (49 U.S.C. 5101 et seq.). 
Section 5103(b) authorizes the Secretary of Transportation to prescribe 
regulations for the safe transportation, including security, of 
hazardous materials in intrastate, interstate, and foreign commerce. 
This rulemaking codifies certain SPs into the HMR.

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

    This final rule is not considered a significant regulatory action 
under Executive Order 12866 (``Regulatory Planning and Review''), as 
supplemented and reaffirmed by Executive Order 13563 (``Improving 
Regulation and Regulatory Review''), stressing that, to the extent 
permitted by law, an agency rulemaking action must be based on benefits 
that justify its costs, impose the least burden, consider cumulative 
burdens, maximize benefits, use performance objectives, and assess 
available alternatives, and the Regulatory Policies and Procedures of 
the Department of Transportation (44 FR 11034). Executive Orders 12866 
and 13563 require 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 regulations 
that ``impose the least burden on society.''
    Executive Order 13610, issued May 10, 2012, urges agencies to 
conduct retrospective analyses of existing rules to examine whether 
they remain justified and whether they should be modified or 
streamlined in light of changed circumstances, including the rise of 
new technologies. By building off of each other, these three Executive 
Orders require 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 regulations 
that ``impose the least burden on society.''
    In this final rule, PHMSA is amending the HMR to adopt provisions 
contained in certain widely-used or long-standing SPs that have an 
established safety record. The revisions are intended to provide wider 
access to the regulatory flexibility offered in SPs and eliminate the 
need for numerous renewal requests, thus reducing paperwork burdens and 
facilitating commerce while maintaining an appropriate level of safety. 
Although difficult to quantify, PHMSA assumes that for most regulated 
entities in these categories, the revisions in this final rule require 
little or no change to existing practice or behavior and incremental 
compliance costs will thus be close to zero. At the same time, the 
potential for additional safety benefits is also very limited in these 
cases, as existing practice and operations are already minimizing the 
number of incidents.
    Estimated benefits associated with this rule result from the 
regulated community no longer being required to apply for an SP and 
amount to approximately $14,000 annually. Costs associated with the 
rule are estimated to be negligible annually. Since existing SP holders 
are already complying with the specifications of the current SPs, the 
amendments adopted in this final rule would not impose new obligations 
on current non-holders of SPs. The overall costs and benefits of the 
rule are dependent on the level of pre-existing compliance and the 
overall effectiveness of the new requirements specified in this 
rulemaking.

C. Executive Order 13132

    This final rule has been analyzed in accordance with the principles 
and criteria contained in Executive Order 13132 (``Federalism''), 64 FR 
43255 (Aug. 10. 1999) and the President's May 20, 2009 memorandum (74 
FR 24693 [May 22, 2009]). The requirements in this final rule would 
preempt state, local, and Indian tribe requirements but would not have 
substantial direct effects on the States, the relationship between the 
national government and the States, or the distribution of power and 
responsibilities among the various levels of government. Therefore, the 
consultation and funding requirements of Executive Order 13132 do not 
apply.
    The Federal hazardous materials transportation law, 49 U.S.C. 5101 
et seq., contains an express preemption provision (49 U.S.C. 5125(b)) 
preempting State, local, and Indian tribe 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; or
    (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.
    Federal hazardous materials transportation law provides at 49 
U.S.C. 5125(b)(2) that, if DOT issues a regulation concerning any of 
these subjects, DOT must determine and publish in the Federal Register 
the effective date of Federal preemption. The effective date may not be 
earlier than the 90th day following the date of issuance of the final 
rule and not later than 2 years after the date of issuance.
    This rule would address subject areas (1), (2), (3), and (5) above 
and 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. The effective 
date of Federal preemption is April 20, 2016.

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''). Because this final rule 
does not have tribal implications and does not impose substantial 
direct compliance costs, the funding and consultation requirements of 
Executive Order 13175 do not apply.

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

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an 
agency to review regulations to assess their impact on small entities 
unless the agency determines that a rule is not expected to have a 
significant impact on a substantial number of small entities. The 
primary costs to small entities associated with this rule include 
developing and updating a risk assessment, developing and updating 
operating procedures, and additional training for hazmat employees who 
perform loading and unloading operations.
    PHMSA expects the impacts of this rule will be limited for many 
small entities due to their compliance with other existing Federal 
regulations. In this rulemaking, PHMSA also explicitly acknowledges 
that many regulated entities are holders of SPs or are part of industry 
associations with voluntary codes of safe practice, and that these may 
be sufficient for compliance with the final rule as long as all of the 
relevant safety areas are addressed and documented. For regulated 
entities in these categories, the rulemaking requires little or no 
change to existing practices or behavior and incremental compliance 
costs will thus be close to zero. Therefore, the benefit and cost 
figures discussed below should be viewed as upper bounds, both of which 
will be reduced by the extent of current practice.
    PHMSA estimates that there are 50 potentially affected small 
entities. The annualized documentation cost for developing and updating 
the risk assessment and the operating procedures is estimated to be 
$375 per small entity. The annualized cost of additional training for 
affected employees is estimated to be approximately $5.50 per employee. 
Further, PHMSA estimates that approximately 50% of small businesses are 
already implementing procedures that would be compliant with this 
rulemaking. Based upon the above estimates and assumptions, PHMSA 
certifies that this rulemaking does not have a significant economic 
impact on a substantial number of small entities. Further information 
on the estimates and assumptions used to evaluate the potential impacts 
to small entities is available in the Regulatory Impact Assessment that 
has been placed in the public docket for this rulemaking.

F. Paperwork Reduction Act

    PHMSA currently has an approved information collection under OMB 
Control No. 2137-0051, entitled ``Special Permits and Approvals,'' 
expiring on May 31, 2018. Section 1320.8(d), Title 5, Code of Federal 
Regulations, requires PHMSA to provide interested members of the public 
and affected agencies an opportunity to comment on information 
collection and recordkeeping requests. This rulemaking adds new 
exceptions to the HMR while eliminating the need for persons to apply 
for a SP, resulting in a decrease in burden. PHMSA estimates the 
reduction in information collection burden as follows:

OMB Control No. 2137-0051: SPs and Approvals
Decrease in Annual Number of Respondents: 96
Decrease in Annual Responses: 96
Decrease in Annual Burden Hours: 194
Decrease in Annual Burden Cost: $14,027

    There are 832 grantees associated with the 96 SPs being adopted in 
this rulemaking. Over 10 years, a SP would on average be renewed twice, 
resulting in 1,664 renewals (832 x 2). The average number of 
applications per year would be approximately 166 (1,664/10). The annual 
estimated cost savings would total $14,027 (166 number of renewals per 
year x $39.50/hr. preparation cost + 166 renewals per year x $45.00/hr 
compliance cost).
    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. Regulatory Identifier Number (RIN)

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

H. Unfunded Mandates Reform Act

    This rulemaking does not impose unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. PHMSA has concluded that the rule 
will not impose annual expenditures of $141.3 million on State, local, 
or tribal governments or the private sector, and thus does not require 
an Unfunded Mandates Act analysis.

I. Executive Order 13609 and International Trade Analysis

    Under E.O. 13609, 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 rule to ensure that it does not cause 
unnecessary obstacles to foreign trade. Accordingly, this rulemaking is 
consistent with E.O. 13609 and PHMSA's obligations under the Trade 
Agreement Act, as amended.

J. Environmental Assessment and NEPA Analysis

    PHMSA is amending the HMR by adopting provisions contained in 
certain widely-used or long-standing SPs that have an established 
safety record. The revisions are intended to provide wider access to 
the regulatory flexibility offered in SPs and eliminate the need for 
numerous renewal requests, thus reducing paperwork burdens and 
facilitating commerce while maintaining an appropriate level of safety.
    The National Environmental Policy Act (NEPA), 42 U.S.C. 4321-4375, 
requires that federal agencies analyze

[[Page 3665]]

proposed actions to determine whether the action will have a 
significant impact on the human environment. The Council on 
Environmental Quality (CEQ) regulations order federal agencies to 
conduct an environmental review considering (1) the need for the 
proposed action (2) alternatives to the proposed action (3) probable 
environmental impacts of the proposed action and alternatives and (4) 
the agencies and persons consulted during the consideration process. 40 
CFR 1508.9(b). A detailed NEPA assessment has been placed in the docket 
for this rulemaking for public review.

K. 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.). You may review DOT's complete Privacy Act Statement in 
the Federal Register published on April 11, 2000 (65 FR 19477) which 
may be viewed at: http://www.gpo.gov/fdsys/pkg/FR-2000-04-11/pdf/00-8505.pdf.

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 does not involve voluntary consensus standards.

    381 For railroad flagging kits, see Sec.  173.184 (c) of this 
subchapter.
    382 Packages containing toy plastic or paper caps for toy pistols 
described as ``UN0349, Articles, explosive, n.o.s. (Toy caps), 1.4S'' 
or ``NA0337, Toy caps, 1.4S'' are not subject to the subpart E 
(labeling) requirements of this part when offered for transportation by 
motor vehicle, rail freight, cargo vessel, and cargo aircraft and, 
notwithstanding the packing method assigned in Sec.  173.62 of this 
subchapter, in conformance with the following conditions:
    a. The toy plastic or paper caps must be in the form of sheets, 
strips, rolls, or individual caps;
    b. The caps must not contain more than an average of twenty-five 
hundredths of a grain of explosive composition per cap;
    c. The caps must be packed inside packagings constructed of 
cardboard not less than 0.013-inch in thickness, metal not less than 
0.008-inch in thickness, non-combustible plastic not less than 0.015-
inch in thickness, or a composite blister package consisting of 
cardboard not less than 0.013-inch in thickness and non-combustible 
plastic not less than 0.005-inch in thickness that completely encloses 
the caps;
    d. The minimum dimensions of each side and each end of the 
cardboard packaging must be 1/8th inch in height or more;
    e. The number of caps inside each packaging must be limited so that 
not more than 10 grains of explosives composition may be packed into 
one cubic inch of space, and not more than 17.5 grains of the explosive 
composition of toy caps may be packed in any inner packaging;
    f. Inner packagings must be packed in outer packagings meeting PG 
II performance criteria;
    g. Toy caps may be packed with non-explosive or non-flammable 
articles provided the outer packagings are marked as prescribed in this 
paragraph;

must be packed in a strong outer packaging; or
    (ii) The container is not over 114 L (30 gallons) capacity and 
charged to not more than 75 psig (517.1 kPa) at 21.1 [deg]C (70 
[deg]F).
    (3) When in a metal aerosol container (see Sec.  171.8 of this 
subchapter for the definition of aerosol). Authorized containers 
include non-specification, DOT 2P (Sec.  178.33 of this subchapter), 
DOT 2Q (Sec.  178.33a of this subchapter), or DOT 2Q1 (Sec.  178.33(d)

    (iii) Liquid fill. The liquid content of the material and gas must 
not completely fill the container at 54.4 [deg]C (130 [deg]F).
    (iv) Outer packaging. The containers must be packed in strong outer 
packagings.
    (v) Pressure testing. Except as otherwise provided in this 
paragraph, each container, after it is filled, must be subjected to a 
test performed in a hot water bath; the temperature of the bath and the 
duration of the test must be such that the internal pressure reaches 
that which would be reached at 55 [deg]C (131 [deg]F), or 50 [deg]C 
(122 [deg]F) if the liquid phase does not exceed 95% of the capacity of 
the container at 50 [deg]C (122 [deg]F)). If the contents are sensitive 
to heat, the temperature of the bath must be set at between 20 [deg]C 
(68 [deg]F) and 30 [deg]C (86 [deg]F) but, in addition, one container 
in 2,000 must be tested at the higher temperature. No leakage or 
permanent deformation of a container may occur. However, instead of 
this standard water bath test, container(s) may be tested using one of 
the following methods subject to certain conditions--
    (A) Alternative water bath test. (1) One filled container in a lot 
of 2,000 must be subjected to a test performed in a hot water bath; the 
temperature of the bath and the duration of the test must be such that 
the internal pressure reaches that which would be reached at 55 [deg]C 
(131 [deg]F). If the container shows evidence of leakage or permanent

[[Page 3678]]

deformation, the lot of 2,000 containers must be rejected;
    (2) A second filled container in the lot of 2,000 must be weighed 
and compared to the weight specification for the containers as 
documented in the operating procedures for the weight test. Failure of 
the container to meet the weight specification is evidence of leakage 
or overfilling and the lot of 2,000 must be rejected;
    (3) The remainder of the containers in the lot of 2,000 must be 
visually inspected (e.g, examination of the seams). Containers showing 
evidence of leakage or overfilling must not be transported; and
    (4) Each person employing this test must maintain a copy of the 
operating procedures (or an electronic file thereof) that is accessible 
at, or through, its principal place of business and must make the 
procedures available upon request, at a reasonable time and location, 
to an authorized official of the Department.
    (B) Automated pressure test. Each person employing an automated 
process for pressure testing of filled containers must develop 
procedures for implementation of the test. Each person must maintain a 
copy of the procedures (or an electronic file thereof) that is 
accessible at, or through, its principal place of business and must 
make the procedures available upon request, at a reasonable time and 
location, to an authorized official of the Department. The procedures 
must, at a minimum, include instruction on the following:
    (1) Pressure specifications. Each person must specify pressure 
standard(s) (e.g. a pressure limit or range) for a container respective 
of the design and/or contents. Each container, after it is filled, must 
be pressure checked and compared to the standards. For a pressure 
limit, any container exceeding the pressure limit must be rejected. For 
a pressure range, any container outside of the set range must be 
rejected. The instruments used to determine the pressure must be 
properly calibrated before a production run to an accuracy of +/- or 
better; and
    (2) Periodic inspection. At designated intervals, a randomly 
selected container must be inspected for proper closure and 
verification of filling pressure. If a container shows signs of 
improper closure or over-filling, five (5) additional randomly selected 
containers must be inspected. If any of the additional containers show 
signs of improper closure or over-filling, all containers produced 
since the last inspection must be rejected.
    (C) Weight test. Each person employing a weight test of filled 
containers must develop procedures for implementation of the test. Each 
person must maintain a copy of the procedures (or an electronic file 
thereof) that is accessible at, or through, its principal place of 
business and must make the procedures available upon request, at a 
reasonable time and location, to an authorized official of the 
Department. The procedures must, at a minimum, include instruction on 
the following:
    (1) Weight specifications. Each person must specify target weight 
specifications for a particular container. Each container, after it is 
filled, must be weighed and compared to the target weight specification 
for the container. Any container outside the target weight 
specification is an indication of leakage or overfilling and must be 
rejected. The instruments used to determine the weight must be properly 
calibrated before a testing run and be sufficiently sensitive to 
measure within 0.10 g of the true weight of the container;
    (2) Heat testing and pressure limits. One container out of each lot 
of successfully filled containers must be heat tested by raising the 
internal pressure until it reaches that which would be reached at 55 
[deg]C (131 [deg]F). The lot size should be no greater than 2,000. If 
the pressure in the container exceeds the maximum pressure allowed for 
the container type or if the container shows signs of leakage or 
permanent deformation, the lot must be rejected. Alternatively, five 
(5) additional randomly selected containers from the lot may be tested 
to qualify the lot but if any of the five containers fail the test, the 
entire lot must be rejected;
    (3) Periodic inspection. At intervals of not more than 10 minutes, 
a randomly selected container must be inspected for proper closure and 
verification of filling pressure. If a container shows signs of 
improper closure or over-filling, five (5) additional randomly selected 
containers must be inspected. If any of the additional containers show 
signs of improper closure or over-filling, all containers produced 
since the last inspection must be rejected; and
    (4) Visual inspection. Each container must be visually inspected 
prior to being packed. Any container showing signs of leakage or 
permanent deformation must be rejected.
    (D) Leakage test. (1) Pressure and leak testing before filling. 
Each empty container must be subjected to a pressure equal to or in 
excess of the maximum expected in the filled containers at 55 [deg]C 
(131 [deg]F) or 50 [deg]C (122 [deg]F) if the liquid phase does not 
exceed 95% of the capacity of the container at 50 [deg]C (122 [deg]F). 
This must be at least two-thirds of the design pressure of the 
container. If any container shows evidence of leakage at a rate equal 
to or greater than 3.3 x 10-2 mbar L/s at the test pressure, 
distortion or other defect, it must be rejected; and
    (2) Testing after filling. The person filling each container must 
ensure that the crimping equipment is set appropriately and the 
specified propellant is used before filling a container. Once filled, 
each container must be weighed and leak tested. The leak detection 
equipment must be sufficiently sensitive to detect at least a leak rate 
of 2.0 x 10-3 mbar L/s at 20 [deg]C (68 [deg]F). Any filled 
container which shows evidence of leakage, deformation, or overfilling 
must be rejected.
    (vi) Each outer packaging must be marked ``INSIDE CONTAINERS COMPLY 
WITH PRESCRIBED REGULATIONS.''
    (4) Gas samples must be transported under the following conditions:
    (i) A gas sample may only be transported as non-pressurized gas 
when its pressure corresponding to ambient atmospheric pressure in the 
container is not more than 105 kPa absolute (15.22 psia).
    (ii) Non-pressurized gases, toxic (or toxic and flammable) must be 
packed in hermetically sealed glass or metal inner packagings of not 
more than one L (0.3 gallons) overpacked in a strong outer packaging.
    (iii) Non-pressurized gases, flammable must be packed in 
hermetically sealed glass or metal inner packagings of not more than 5 
L (1.3 gallons) and overpacked in a strong outer packaging.
    (5) For limited quantities of Division 2.2 gases with no subsidiary 
risk, when in a non-DOT specification or a specification DOT 2S (Sec.  
178.33b of this subchapter) plastic aerosol container (see Sec.  171.8 
of this subchapter for the definition of aerosol) provided all of the 
following conditions are met. Additional exceptions for aerosols 
conforming to this paragraph (a)(5) are provided in paragraph (i) of 
this section.
    (i) Capacity. The capacity of the container must not exceed 1 L 
(61.0 cubic inches).
    (ii) General pressure conditions. Authorized plastic aerosol 
containers and associated pressure limitations are provided in the 
following table. The pressure in the container must not exceed 160 psig 
at 54.4 [deg]C (130 [deg]F). The container must be capable of 
withstanding without bursting a pressure of at least one and one-half 
times the equilibrium pressure of the contents at 54.4 [deg]C (130 
[deg]F).

    (iii) Liquid fill. Liquid content of the material and gas must not 
completely fill the container at 54.4 [deg]C (130 [deg]F).
    (iv) Outer packaging. The containers must be packed in strong outer 
packagings.
    (v) Pressure testing. Except as provided in paragraph (a)(5)(vi) of 
this section, each container must be subjected to a test performed in a 
hot water bath. The temperature of the bath and the duration of the 
test must be such that the internal pressure reaches that which would 
be reached at 55 [deg]C (131 [deg]F) or 50 [deg]C (122 [deg]F) if the 
liquid phase does not exceed 95% of the capacity of the container at 50 
[deg]C (122 [deg]F). If the contents are sensitive to heat, or if the 
container is made of plastic material which softens at this test 
temperature, the temperature of the bath must be set at between 20 
[deg]C (68 [deg]F) and 30 [deg]C (86 [deg]F) but, in addition, one 
container in 2,000 must be tested at the higher temperature. No leakage 
or permanent deformation of a container is permitted except that a 
plastic container may be deformed through softening provided that it 
does not leak.
    (vi) Leakage test. As an alternative to the hot water bath test in 
paragraph (a)(5)(v) of this section, testing may be performed as 
follows:
    (A) Pressure and leak testing before filling. Each empty container 
must be subjected to a pressure equal to or in excess of the maximum 
expected in the filled containers at 55 [deg]C (131 [deg]F) or 50 
[deg]C (122 [deg]F) if the liquid phase does not exceed 95% of the 
capacity of the container at 50 [deg]C (122 [deg]F). This must be at 
least two-thirds of the design pressure of the container. If any 
container shows evidence of leakage at a rate equal to or greater than 
3.3 x 10-2 mbar L/s at the test pressure, distortion or 
other defect, it must be rejected; and
    (B) Testing after filling. Prior to filling, the filler must ensure 
that the crimping equipment is set appropriately and the specified 
propellant is used before filling the container. Once filled, each 
container must be weighed and leak tested. The leak detection equipment 
must be sufficiently sensitive to detect at least a leak rate of 2.0 x 
10-3 mbar L/s at 20 [deg]C (68 [deg]F). Any filled container 
that shows evidence of leakage, deformation, or excessive weight must 
be rejected.
    (vii) Each outer packaging must be marked ``INSIDE CONTAINERS 
COMPLY WITH PRESCRIBED REGULATIONS.''
    (b) Exceptions for foodstuffs, soap, biologicals, electronic tubes, 
and audible fire alarm systems. Limited quantities of compressed gases 
(except Division 2.3 gases) for which exceptions are provided as 
indicated by reference to this section in Sec.  172.101 of this 
subchapter, when in conformance with one of the following paragraphs, 
are excepted from labeling, except when offered for transportation or 
transported by aircraft, and the specification packaging requirements 
of this subchapter. For transportation by aircraft, the package must 
conform to the applicable requirements of Sec.  173.27 and only 
packages of hazardous materials authorized aboard passenger-carrying 
aircraft may be transported as a limited quantity. In addition, 
shipments are not subject to subpart F (Placarding) of part 172 of this 
subchapter, to part 174 of this subchapter, except Sec.  174.24, and to 
part 177 of this subchapter, except Sec.  177.817. Additional 
exceptions for certain compressed gases in limited quantities and the 
ORM-D hazard class are provided in paragraph (i) of this section.
    (1) Foodstuffs or soaps with soluble or emulsified compressed gas 
are authorized in non-refillable metal or plastic containers not to 
exceed 1 L (61.0 cubic inches) capacity provided the pressure in each 
container does not exceed 140 psig at 54.4 [deg]C (130 [deg]F) unless 
authorized by variation of a container type. For pressures ranging from 
greater than 140 psig to 160 psig, a variation DOT 2P1 or DOT 2Q2 
(Sec. Sec.  178.33(c) and (d) of this subchapter, respectively) 
container must be used. However, the pressure of the contents in the 
container may not be greater than 150 psig at 23.9 [deg]C (75 [deg]F). 
Plastic containers may only contain Division 2.2 non-flammable soluble 
or emulsified compressed gas. Metal or plastic containers must be 
capable of withstanding, without bursting, a pressure of at least one 
and one-half times the equilibrium pressure of the contents at 54.4 
[deg]C (130 [deg]F).

to the motor vehicle, and are:
    (A) Permanently affixed to a steel base structure,
    (B) Permanently affixed to a trailer, or
    (C) Manufactured with a rigid internal structure designed for 
transportation and stacking conditions such that they do not leak and 
do not deteriorate, distort, or become damaged in a manner that could 
adversely affect their safety or reduce their strength in 
transportation, cause instability in stacks of refrigerating machines, 
or cause damage to these machines in a way that is likely to reduce 
safety in transportation.
    (ii) Testing. Used refrigerating machines returned from their 
rental locations must be transported back to an authorized original 
equipment manufacturer service facility and undergo maintenance, repair 
and/or replacement that renders these machines operational at the same 
level as that of new refrigerating machines, and must undergo a leak 
test by a certified technician, prior to re-shipment.
    (f) Accumulators (Articles, pressurized pneumatic or hydraulic 
containing non-flammable gas). The following applies to accumulators, 
which are hydraulic accumulators containing nonliquefied, nonflammable 
gas, and nonflammable liquids or pneumatic accumulators containing 
nonliquefied, nonflammable gas, fabricated from materials which will 
not fragment upon rupture.
    (1) Accumulators installed in motor vehicles, construction

Sec.  174.67  Tank car unloading.

* * * * *
    (g) The valve cap, or the reducer when a large outlet is to be 
used, must be removed with a suitable wrench after the set screws are 
loosened and a pail must be placed in position to catch any liquid that 
may be in the outlet chamber. If the valve cap or reducer does not 
unscrew easily, it may be tapped lightly with a mallet or wooden block 
in an upward direction. If leakage shows upon starting the removal, the 
cap or reducer may not be entirely unscrewed. Sufficient threads must 
be left engaged and sufficient time allowed to permit the controlled 
escape of any accumulation of liquid in the outlet chamber. If the 
leakage stops or the rate of leakage diminishes materially, the cap or 
reducer may be entirely removed. If the initial rate of leakage 
continues, further efforts must be made to seat the outlet valve (see 
paragraph (f) of this section). If this fails, the cap or reducer must 
be screwed up tight and the tank must be unloaded through the dome. If 
upon removal of the outlet cap the outlet chamber is found to be 
blocked with frozen liquid or any other matter, the cap must be 
replaced immediately and a careful examination must be made to 
determine whether the outlet casting has been cracked. If the 
obstruction is not frozen liquid, the car must be unloaded through the 
dome. If the obstruction is frozen liquid and no crack has been found 
in the outlet casting, the car may, if circumstances require it, be 
unloaded from the bottom by removing the cap and attaching unloading 
connections immediately. Before opening the valve inside the tank car 
with a frozen liquid blockage:
    (1) Steam must be applied to the outside of the outlet casting or 
the outlet casting must be wrapped with burlap or other rags and hot 
water applied to the wrapped casting to melt the frozen liquid; or
    (2) For combustible liquid or Class 3 liquid petroleum distillate 
fuels, the blockage may be cleared by attaching a fitting to the outlet 
line and applying nitrogen at a pressure not to exceed 100 psig.

rejected. All containers constituting a lot shall be of like material, 
size, design construction, finish, and quality.
    (c) Marking. By means of printing, lithographing, embossing, or 
stamping, each container must be marked:
    (1) DOT-2P1.
    (2) With the name or symbol of the person making the mark. A 
symbol, if used, must be registered with the Associate Administrator.

47. Sections 178.33d, 178.33d-1, 178.33d-2 and 178.33d-3 are added to 
subpart B to read as follows:


Sec.  178.33d  Specification 2Q; inner nonrefillable metal receptacle 
variations.


Sec.  178.33d-1  Compliance.

    Required in all details.


Sec.  178.33d-2  Variation 1.

    Notwithstanding the variation provided in this paragraph, each 
container must otherwise conform to a DOT 2Q container in accordance 
with Sec.  178.33a. The following conditions also apply under Variation 
1--
    (a) Type and size. The maximum capacity of containers in this class 
may not exceed 0.40 L (24.4 cubic inches). The maximum inside diameter 
shall not exceed 2.1 inches.
    (b) Manufacture. Ends: The top of the container must be designed 
with a pressure relief system consisting of radial scores on the top 
seam(s). The bottom of the container must be designed to buckle at a 
pressure greater than the pressure at which the top buckles and vents.
    (c) Wall thickness. The minimum wall thickness for any container 
shall be 0.0085 inches.
    (d) Tests. (1) Two containers (one without a pressure relief system 
and one with) out of each lot of 25,000 or less, successively produced 
per day shall be pressure tested to destruction at gauge pressure. The 
container without a pressure relief system must not burst below 320 
psig. The container assembled with a pressure relief system as 
described in paragraph (b) of this section must be tested to 
destruction. The bottom of the container must buckle at a pressure 
greater than the pressure at which the top buckles and vents.
    (2) Each such 25,000 containers or less, successively produced per 
day, shall constitute a lot and if the test container(s) shall fail, 
the lot shall be rejected. Otherwise, ten (10) additional pairs of 
containers may be selected at random and subjected to the test under 
which failure occurred. Should any of the containers thus tested fail, 
the entire lot must be rejected. All containers constituting a lot 
shall be of like material, size, design construction, finish, and 
quality.
    (e) Marking. By means of printing, lithographing, embossing, or 
stamping, each container must be marked:
    (1) DOT-2Q1.
    (2) With the name or symbol of the person making the mark. A 
symbol, if used, must be registered with the Associate Administrator.


Sec.  178.33d-3  Variation 2.

    Notwithstanding the variation provided in this paragraph, each 
container must otherwise conform to a DOT 2Q container in accordance 
with Sec.  178.33a. The following conditions also apply under Variation 
2--
    (a) Manufacture. Ends: The ends shall be designed to withstand 
pressure and the container equipped with a pressure relief system 
(e.g., rim-venting release or a dome expansion device) designed to 
buckle prior to the burst of the container.
    (b) Tests. (1) One out of each lot of 25,000 containers or less, 
successively produced per day shall be pressure tested to destruction 
at gauge pressure and must not burst below 270 psig. For containers 
with a pressure relief system as described in paragraph (a) of this 
section and assembled, failure at a location other than the pressure 
relief system will reject the lot.
    (2) Each such 25,000 containers or less, successively produced per 
day, shall constitute a lot and if the test container(s) shall fail, 
the lot shall be rejected. Otherwise, ten (10) additional containers of 
each container design produced may be selected at random and subjected 
to the test. These containers shall be complete with ends assembled. 
Should any of the containers thus tested fail, the entire lot must be 
rejected. All containers constituting a lot shall be of like material, 
size, design construction, finish, and quality.
    (c) Marking. By means of printing, lithographing, embossing, or 
stamping, each container must be marked:
    (1) DOT-2Q2.
    (2) With the name or symbol of the person making the mark. A 
symbol, if used, must be registered with the Associate Administrator.
