I. Background
On January 23, 2015, PHMSA published a notice of proposed
rulemaking (NPRM) [Docket No. PHMSA-2013-0225 (HM-218H); 80 FR 3787]
that proposed amendments to update and clarify existing requirements of
the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180). Both
the NPRM and this final rule are part of the Department of
Transportation's Retrospective Regulatory Review (RRR) process designed
to identify ways to improve the HMR through the extensive review of
both the HMR and previously issued letters of interpretation. In
addition, the NPRM proposed regulatory requirements in response to
seven (7) petitions for rulemaking and two (2) NTSB Safety
Recommendations. The changes proposed in the NPRM are summarized below:

A discussion of the comments and PHMSA's position regarding action
in this final rule is provided below. We begin with a discussion of
comments on the proposals to revise the HMR based on petitions for
rulemaking and NTSB Safety Recommendations. Note that additional
comments are addressed in the Section-by-Section Review. Further, we
discuss comments and proposals not adopted under this final rule, later
discussing comments that are outside the scope of the proposals of this
rulemaking.
A. Petitions for Rulemaking and NTSB Safety Recommendations
Amendments to the HMR for Organic Peroxides, Self-Reactive Substances
and Explosives (P-1590)
The DGAC submitted a petition (P-1590) requesting that PHMSA amend
the HMR by removing the PG II designation in Column (5) of the Sec.
172.101 HMT for all organic peroxides (Division 5.2), self-reactive
substances (Division 4.1), and explosives (Class 1). The DGAC states
that organic peroxides, self-reactive substances, and explosives are
not assigned a packing group in accordance with either the HMR or
international regulations. Despite the absence of regulatory language
for determining a packing group assignment for these materials, proper
shipping names for these materials listed in the HMT are assigned a
default PG II. The DGAC asserts that the presence of a PG assignment
for these entries is a constant source of confusion that leads to
frustration of shipments, further indicating that the frustration
typically occurs when shipping papers are inspected by carrier staff
and enforcement personnel along the transport chain with respect to the
Sec. 172.202(a)(4) requirement to include the ``packing group in Roman
numerals, as designated for the hazardous material in Column (5) of the
Sec. 172.101 table.''
The DGAC notes that while Sec. 172.202(a)(4) also excepts organic
peroxides, self-reactive substances, and explosives from the
requirement to provide a PG as part of the required description, a
great deal of confusion is created given that, irrespective of this
exception, PGs are provided for these materials in the Sec. 172.101
HMT. Furthermore, the DGAC also states that the HMR are inconsistent
with international regulations, as a PG is not indicated for these
materials in their respective hazardous materials (dangerous goods)
tables. In addition, those regulations restrict the provision of a PG
in the transport document basic description to materials where a PG has
been assigned in accordance with classification requirements: Thus,
with no PG indicated for these substances in the respective lists, it
is inappropriate to provide a PG in the hazardous materials description
on a shipping paper under international regulations. Consequently,
provision of a PG for domestic transportation would constitute a
violation of international regulations for international
transportation.
The DGAC states that removing the PG for these materials from the
HMT would impose no additional costs and would, in fact, result in a
net savings since many unnecessary delays in hazardous material
shipments would be avoided. However, the DGAC did not provide a
specific figure for the anticipated net savings.
The DGAC also states that the packaging provisions in Part 173 for
these materials indicate the level of performance required. Therefore,
although certain packagings must meet PG II performance levels, they do
not indicate a degree of danger or the variation to PG I or PG III
packagings.
In the NPRM, PHMSA proposed to remove the PG II designation from
Column (5) of the HMT for organic peroxides (Division 5.2), self-
reactive substances (Division 4.1), and explosives (Class 1) as
requested in the petition. We agree with the petitioner that, when the
PG does not relate to the degree of hazard of the material based on
classification criteria but rather is broadly assigned to an entire
group of materials for purposes of applying regulatory requirements,
there is limited value in requiring an indication of the PG on a
shipping paper. PHMSA solicited comment on the safety implications and
net benefits of such a change and, as a result, received three comments
from ACA, IME, and DGAC in support of the proposed revision. The ACA
commented that international harmony is vitally important and will help
maintain the exemplary safety record for the transport of hazardous
materials. In its comments, IME stated that in a letter to PHMSA dated
June 20, 2012, it supported the petition submitted by DGAC,
acknowledging that ``IME has encountered enforcement officials'
confusion over not showing the packing group on Class 1 shipping
papers, as is allowed by regulation. Shipping paper violations can lead
to out-of-service orders and have serious consequences to IME members'
ability to operate as a motor carrier or hold special permits and
approvals.'' IME noted that its ``experience has not changed in the
intervening time period, and we continue to support the position
advocated by DGAC. We believe that the action being contemplated by
PHMSA will eliminate the confusion that is engendered by the current
default assignment.'' IME further commented that the removal of the PG
II designation would not result in the incorrect packaging of Class 1
explosives in other than an approved package because of the Sec.
173.60(a) requirement that a packaging used for Class 1 (explosives)
materials must meet the PG II requirements. In addition to its
supporting comments, IME requested that shippers who currently include
the PG designation on shipping papers continue to be able to do so
without risk of incurring a violation.
Taking into account the reasons for the removal of the PG II
designation from Column (5) of the HMT for organic peroxides, self-
reactive substances, and explosives, PHMSA disagrees with IME that
shippers should be provided the option of electively indicating a PG on
a shipping paper for a HMT entry that is no longer assigned a PG
designation. PHMSA believes that allowing this practice would continue
to perpetuate confusion and result in the continued frustration of
shipments. Further, allowing a PG on a shipping paper for a HMT entry
that is not assigned a PG designation for domestic transportation would
not be in alignment with, and would continue to constitute a violation
of, international regulations for international transportation. For
these reasons, we are revising Column (5) of the HMT as proposed in the
NPRM without an exception to voluntarily apply the PG II designation on
a shipping paper.

Marking Requirements for Poison-by-Inhalation Materials (P-1591)
Air Products and Chemicals, Inc. submitted a petition (P-1591)
requesting that PHMSA amend the marking requirements for poison-by-
inhalation hazard (PIH) materials that are shipped in accordance with
the IMDG Code or Transport Canada's Transportation of Dangerous Goods
(TDG) Regulations. Specifically, the petitioner requested that PHMSA
modify Sec. 171.23(b)(10)(iv)(A) and (B) to remove the phrase
``regardless of the total quantity contained in the transport vehicle
or freight container'' in both paragraphs to align part 171, subpart C
requirements for use of international regulations with the poisonous
hazardous material marking requirements in Sec. 172.313(c), which
offers exceptions based on Hazard Zone, quantity, and number of
distinct materials.
Subpart C of part 171 specifies requirements for shipments offered
for transportation or transported in the United States under
international regulations. For PIH material, subparagraphs (A) and (B)
of Sec. 171.23(b)(10)(iv) require that the transport vehicle or
freight container must be marked with the identification numbers for
the hazardous material, regardless of the total quantity contained in
the transport vehicle or freight container, in the manner specified in
Sec. 172.313(c) [i.e., the HMR] and placarded as required by subpart F
of part 172. The petitioner stated that the phrase ``regardless of the
total quantity contained in the transport vehicle or freight
container'' gives the appearance that the identification number marking
requirement is applicable to any quantity, the remainder of the
sentence states that the marking must be ``in the manner specified in
Sec. 172.313(c) of this subchapter,'' which provides an entirely
different requirement.
Section 172.313(c) specifies marking requirements for non-bulk
packages of PIH material contained in transport vehicles or freight
containers subject to certain provisions and limitations. Section
172.313(c)(2) states, the transport vehicle or freight container is
loaded at one facility with 1,000 kg (2,205 pounds) or more aggregate
gross weight of the material in non-bulk packages marked with the same
proper shipping name and identification number, meaning that unless
this criteria is met, marking the identification number on the
transport vehicle or freight container is not required. The petitioner
indicated that the inconsistency of Sec. Sec. 171.23(b)(10)(iv)(A) and
(B) and 172.313(c) is a source of confusion.
Air Products and Chemicals, Inc. also identified a potential
discrepancy when transporting internationally to or from the United
States in accordance with Sec. 171.23, as the requirement to mark all
quantities of PIH material is more restrictive and costly than the
current marking requirements for the same materials when transported
domestically under the HMR in accordance with Sec. 172.313(c). The
petitioner points out that under both the IMDG and the TDG there are no
additional marking requirements for transport units carrying PIH
materials in non-bulk packages similar to the provisions found in Sec.
172.313(c). Therefore, for quantities of PIH materials in non-bulk
packages (less than 1,000 kg per UN number), all three regulations are
not aligned.
The petitioner states that it has had numerous shipments of PIH
materials frustrated because of this confusing requirement and that the
additional marking causes economic hardship and transit delays due to
additional labor necessary to apply the extra UN identification numbers
at the port. Air Products and Chemicals, Inc. provided neither a
specific cost figure for these frustrated shipments nor the anticipated
net savings of a regulatory change.
In the NPRM, PHMSA stated that the intent of the requirements in
Sec. 171.23(b)(10)(iv) is to provide hazard communication for
international shipments of PIH materials transiting the United States
under either the IMDG Code or the TDG equivalent to those established
in the HMR, not to impose more restrictive requirements. The removal of
the phrase referring to a ``total quantity'' will reduce potential
confusion due to differences in inspection interpretations, handling
costs, and transit time while maintaining an acceptable level of hazard
communication for PIH materials. Therefore, PHMSA proposed to amend
Sec. 171.23(b)(10)(iv)(A) and (B) by removing the phrase ``regardless
of the total quantity contained in the transport vehicle or freight
container'' from each subparagraph.
In the NPRM, PHMSA solicited comment on the safety implications of
such a change, as well as the net benefit (e.g., a decrease in the
number of frustrated shipments). We received only positive comments on
this proposal. Air Products and Chemicals, Inc. supported the proposed
change and commented:
The safety of transporting PIH materials will actually be
improved with this proposed regulation change. The effectiveness of
hazard communication will not be reduced as the current UN marking
requirement (for all quantities) provides no additional benefit from
a hazard communication or emergency response perspective. What we do
see is elimination of confusion and a requirement that would be much
more consistent with the IMDG and TDG regulations, as well. We
understand the importance of consistency between the regulations.
Consistency goes a long way in eliminating confusion, especially in
an emergency response situation when effective accurate
communication is extremely important. The display of UN ID numbers
on a transport vehicle for small individual quantities falsely gives
the impression that there are large amounts of the hazardous
material. In an Emergency Response situation, it is not wise to
cause reactions that are based on a representation of a large
quantity, when in fact, there is no large quantity. Effective
emergency response is based both on knowledge of the hazards and
knowledge of the quantity. The more consistency we have for hazard
communication processes, the better.
The DGAC also supported the proposed change and commented:
This revision will eliminate confusion between the requirements
for domestic shipments and international shipments. In addition,
this revision is consistent with the goal to harmonize domestic
regulations with the international requirements.
For these reasons, we are revising Sec. 171.23(b)(10)(iv)(A) and
(B) as proposed in the January 23, 2015 NPRM.
Emergency Response Telephone Number (P-1597)
The DGAC submitted a petition (P-1597) requesting that PHMSA amend
the emergency response telephone number requirements to prohibit the
use of alphanumeric telephone numbers and only permit numeric telephone
numbers since, currently, the HMR does not specifically limit the
telephone numbers to be numeric under Sec. 172.604(a). The DGAC stated
that although telephone faces historically associated integers with
letters (e.g., 2\ABC\), this is no longer the case in all instances. As
a result, emergency response telephone numbers presented
alphanumerically could cause undesirable delays in acquiring emergency
response information in time-sensitive situations as the first
responder would have to first convert letters to numbers.
The DGAC further noted that PHMSA issued a letter of interpretation
(Ref. No. 04-0032) confirming that alphanumeric presentation of an
emergency response telephone number was acceptable but expressing
concern about the delays it may cause.
In the NPRM, PHMSA proposed the revision to Sec. 172.604(a) as
outlined in
[[Page 35489]]
the petition and noted that the continued use of alphanumeric telephone
numbers could cause unnecessary delays in emergency response
situations. Additionally, PHMSA solicited comment on the cost
implications of the proposed revision and, as a result, received four
comments from AAR, ACA, ATA, and DGAC in support of this revision. The
ATA commented that this revision will decrease chances of death or
injury to transporters and emergency responders and that any minimal
costs associated with transposing a number from its corresponding
letter will be more than outweighed by the safety benefits. The ATA
also noted that this revision will be beneficial to both non-English
speakers and those unfamiliar with the traditional correspondence
between numbers and letters on a telephone keypad. For these reasons,
in this final rule we are revising Sec. 172.604(a) as proposed in the
January 23, 2015 NPRM.
Packaging Requirements for Nitric Acid (P-1601)
The UPS submitted a petition (P-1601) requesting that PHMSA revise
the packaging requirements for ground shipments of nitric acid basing
the petition on four loading and sorting operation incidents that
occurred over a six-month period. The incidents did not result in any
casualties, but varying degrees of property damage were assessed in
each situation. The UPS noted that each incident involved the same
packaging configuration--glass inner packagings within fiberboard outer
packagings--and in each case, a breach of one or more inner packagings
caused leakage, resulting in fumes, followed by the initiation of a
fire involving the fiberboard outer packaging material. The UPS
believes that the packaging requirements of the HMR applicable to
ground shipments of nitric acid do not adequately address the hazards
present.
As provided in Sec. 173.158, packaging for ground shipments of
nitric acid prescribe either outer packaging that is not reactive to
contents or a combination packaging that includes non-reactive
intermediate packaging and absorbent material. However, for
concentrations of less than 90 percent nitric acid, the HMR permits the
use of glass inner packagings of less than 2.5 L placed inside UN
Specification 4G, 4C1, 4C2, 4D, or 4F outer packagings. This latter
configuration is associated with the four incidents referenced by UPS
in its petition for rulemaking.
The UPS proposed that PHMSA change Sec. 173.158(e) to enhance the
packaging requirements applicable to nitric acid in concentrations less
than 90 percent. Under the proposal in P-1601, when in wooden or
fiberboard outer packaging, glass inner packagings used in the
configuration prescribed in Sec. 173.158(e) would be required to be
packed in tightly-closed, non-reactive intermediate packagings and
cushioned with a non-reactive absorbent material. The UPS feels that
the addition of this intermediate packaging would properly address the
hazards present in this concentration of nitric acid and would have
prevented the above incidents from occurring.
In the NPRM, PHMSA proposed to require in Sec. 173.158(e) that
when nitric acid, in concentrations less than 90 percent, is placed in
glass inner packagings to be packaged in wooden or fiberboard outer
packaging, the glass inner packagings must be packed in tightly-closed,
non-reactive intermediate packagings and cushioned with a non-reactive
absorbent material. In addition, PHMSA solicited comment on whether or
not the proposed packaging should be applied to other similar materials
as well as on cost burdens from the increase in packaging requirements.
PHMSA received four comments from ATA, James Scott, UPS, and Veolia in
support of the proposed revision. Veolia commented that it is company
policy to place the inner 2.5 L glass bottles in a poly pail
intermediate packaging or the outer container must include a leak-proof
poly liner, further stating that they have implemented the use of the
additional intermediate packages as an additional precautionary safety
measure to contain leaking nitric acid, should the inner glass bottle
fail. After implementing these packaging procedures, Veolia has not had
any incidents of leaking nitric acid initiating a fire, of fumes, or of
leaking material breaching the outer packaging. James Scott commented
that this packaging requirement would be a cost burden for companies
that still pack nitric acid in glass and further noted that the
addition of intermediate packagings and absorbent material may require
current combination packagings to be modified. Mr. Scott suggested that
this impact can be minimized if flexible intermediate packagings are
allowed and that the word ``rigid'' should not appear as part of the
requirement.
PHMSA received only positive comments on this proposal. As proposed
in the NPRM, the revised Sec. 173.158(e) requires that when placed in
wooden or fiberboard outer packagings, the glass inner packagings must
be packed in tightly-closed, non-reactive intermediate packagings,
cushioned with a non-reactive absorbent material. The use of a flexible
intermediate packaging is authorized, provided it can be tightly-closed
and is non-reactive to the nitric acid. A ``rigid'' intermediate
packaging was not proposed. Therefore, in this final rule, PHMSA is
adopting the revision to Sec. 173.158(e) as proposed in the January
23, 2015 NPRM. PHMSA notes that we did not receive any comments in
response to the NPRM solicitation asking that proposed packaging be
applied to any other specific hazardous materials and therefore, we are
limiting the revision to nitric acid as proposed.
Pressure Test and Internal Visual Inspection Requirements for MC 331
Cargo Tanks (P-1604)
The NPGA submitted a petition (P-1604) requesting that PHMSA modify
the pressure test and visual inspection test requirements applicable to
certain MC 331 specification cargo tanks in dedicated propane delivery
service, commonly known as bobtails, found in Sec. 180.407(c).
Currently, the HMR requires periodic pressure testing and visual
inspection every five years to remain in service; however, the NPGA
petitions PHMSA to extend the requalification period for certain MC 331
cargo tanks from five years to ten years and provides a technical case
for this change.
The NPGA states in its petition that the five-year requalification
period for bobtails is a burden to the propane industry further stating
that these cargo tanks must be taken out of service for a period of up
to a week and that water is introduced into the tank during the
requalification process, which can be detrimental to both the tank and
the contents. Before a tank can be returned to service, it must be
completely free of any water. The NPGA states that this removal from
service hinders a propane company's operations.
In 2001, the NPGA conducted a survey to determine whether companies
that performed the five-year hydrostatic test requirement had
experienced any failures. None of the 203 survey respondents reported a
hydrostatic test failure for tanks of less than 3,500 gallons water
capacity. Based on the results of this survey, the NPGA sponsored a
study by the Battelle Memorial Institute (Battelle), a non-profit
research and development organization, to determine whether a change to
the requalification period would be technically feasible. Battelle
developed crack growth models to estimate the time to failure of a tank
that has undergone several pressure cycles. They also analyzed effects
on the MC
[[Page 35490]]
331 cargo tank under the delivery service load conditions to determine
the estimated life of the tank.
Based on the results of this study, the NPGA and Battelle recommend
that PHMSA modify the requalification period from five years to ten
years for MC 331 cargo tanks that: (1) Are used in dedicated propane
service; (2) have a water capacity less than 3,500 gallons; and (3) are
constructed of non-quenched and tempered (NQT) SA-612 steel and NQT SA-
202 or SA-455 steels, provided the materials have full-size equivalent
(FSE) Charpy Vee notch energy test data that demonstrates 75 percent
shear-area ductility at 32[emsp14][deg]F with an average of three (3)
or more samples greater than 15 ft-lb FSE, and none with less than 10
ft-lb FSE. A copy of this study is in the docket for this rulemaking.
After considering the NPGA survey results, which cite no reported
incidents, and the study commissioned by the NPGA, PHMSA determined
that the petition merited consideration of a rulemaking change. The
NPGA notes there is a strong safety record amongst its members
regarding this issue and the cost savings to the industry would be
significant. The NPGA commented in support of the proposed revision to
the requalification requirements for MC 331 or bobtail cargo tanks and
provided cost estimates as requested by PHMSA. They provide that
requalification pressure tests can cost as much as $3,000 when
factoring in the downtime of the bobtail as well as the labor and fuel
required to drive it to the testing shop or facility. In addition, the
NPGA estimates that there are approximately 18,000 bobtails in service
that would be eligible for the extension to the requalification period.
This represents a total industry cost of about $54 million to requalify
these vehicles by hydrostatic test. If the proposed requirements are
extended to ten years, it would reduce the industry's costs by half,
resulting in approximately $5.4 million on an annual basis.
PHMSA received one anonymous comment concerning the provisions in
Note 5 to the Sec. 180.407(c) table. In addition to MC 331 cargo tanks
constructed of nonquenched and tempered NQT SA-612 steel, Note 5
authorizes a ten-year inspection interval period applicable to cargo
tanks constructed of NQT SA-202 or NQT SA-455 steel. This ten year
interval applies if the materials have full-size equivalent (FSE)
Charpy vee notch (CVN) energy test data that demonstrated 75 percent
shear-area ductility at 32[emsp14][deg]F with an average of three (3)
or more samples greater than 15 ft-lb FSE with no sample less than 10
ft-lb FSE. The commenter states that Note 5 contains very specific
information that is not available to most cargo tank owners or
enforcement personnel. As such, the commenter states that there will be
no way to determine that the cargo tank satisfies the Note 5
requirements on the roadside or at the cargo tanks owner's place of
business without the paperwork to verify compliance. The commenter also
states that PHMSA needs to make clear that if a cargo tank owner cannot
document this information, then the cargo tank is not eligible for the
ten-year requalification period and would be subject to a five-year
requalification interval.
PHMSA agrees that if a cargo tank owner cannot produce
documentation that a MC 331 cargo tank meets the requirements for a
ten-year requalification interval, they are subject to the five-year
requalification interval. Section 178.337-2(a)(3) requires that a MC
331 fabricator shall record the heat, and slab numbers, as well as the
certified Charpy impact values where required, of each plate used in
each cargo tank on a sketch showing the location of each plate in the
shell and heads of the cargo tank. Copies of each sketch shall be
provided to the owner, retained for at least five years by the
fabricator, and made available to duly identified representatives of
the Department of Transportation. PHMSA received no other comments on
this issue and therefore, we are adopting as proposed to revise the
pressure test and internal visual inspection requirements found in
Sec. 180.407(c) for certain MC 331 specification cargo tanks from a
five-year requalification period to a ten-year period.
Mobile Acetylene Trailer Systems (P-1605) and NTSB Safety
Recommendations H-09-01 and H-09-02
The CGA submitted a petition (P-1605) requesting that PHMSA amend
the HMR to incorporate a reference to CGA G-1.6-2011, Standard for
Mobile Acetylene Trailer Systems, Seventh Edition, copyright 2011. This
standard provides minimum requirements necessary for the design,
construction, and operation of mobile acetylene trailer systems, which
consist of acetylene cylinders mounted and manifolded for the purposes
of charging, transporting, and discharging acetylene. It also covers
ground-mounted auxiliary equipment used with mobile acetylene trailers
such as piping, meters, regulators, flash arrestors, and fire
protection equipment.
This petition coincides with two NTSB recommendations (H-09-01 and
H-09-02) issued to PHMSA based on incidents involving mobile acetylene
trailers.\1\ In response to the petition and recommendations, PHMSA
determined that it would consider a rulemaking change. Further detailed
discussion of this issue can be found in the Section-by-Section Review
for Sec. 173.301.

Pressure Relief Devices for Cargo Tanks (P-1609)
The TTMA submitted a petition (P-1609) requesting that PHMSA amend
the requirements of Sec. 180.407 applicable to pressure relief devices
(PRDs). Specifically, TTMA requests that PHMSA revise the HMR to more
clearly establish the set pressure of a PRD for each of the DOT
specification cargo tank motor vehicles. The TTMA states that the
wording of Sec. 180.407(d)(3) and (g)(1)(ii), applicable to the
testing requirements for PRDs, creates issues for persons performing
the testing.
The TTMA points out two specific issues with these paragraphs: The
first is the term ``set-to-discharge.'' On April 9, 2009, PHMSA
published a final rule [Docket No. PHMSA-2006-25910 (HM-218E); 74 FR
16135; effective May 11, 2009], where in an attempt to harmonize with
international standards, PHMSA replaced the phrase ``set-to-discharge''
with ``start-to-discharge.'' The TTMA explains that this is an issue
because the discharge pressure referenced is used to figure the minimum
pressure at which the PRD should reseat. By changing the wording from
``set'' to ``start,'' the reseating pressure changed from a design
requirement to one based on what a given vent actually does under test.
Therefore, instead of testing a PRD knowing its reseating requirements,
testers must perform the test of a given PRD, calculate the reseating
pressure of that particular PRD, and then, retest from that pressure.
Essentially, testers of PRDs could test identical products at different
pressures because the reseat pressure is no longer a fixed design
requirement. This creates inconsistencies between the reseating
pressures of comparable PRDs authorized for identical hazardous
materials service. The TTMA states that this change compromises safety,
instead of promoting it.
The second issue TTMA points out in its petition is in regards to
the term ``the required set pressure.'' This term is problematic in
relation to the continuing operation of existing cargo tanks made to
older specifications in Sec. 180.405(c). As the codes for the older
[[Page 35491]]
specifications of cargo tanks are no longer published, determining
``the required set pressure'' is problematic. This is an issue for
current specifications of cargo tanks as well. There are pressure
allowances during the retesting of pressure relief devices of no more
than 110 percent of the required set pressure (Sec. 180.407(d)(3)) and
the same 10 percent allowance for DOT-400 series cargo tanks (Sec.
178.345-10(d)) creates confusion for current specification cargo tanks.
The TTMA believes this will create an unsafe condition for tanks, as a
PRD is no longer functioning as designed by the manufacturer; thus the
PRD may actually open at higher pressures (near a cargo tank's test
pressure) as opposed to the appropriate lower design pressure.
The TTMA petitioned that PHMSA revise the HMR for testing of PRDs
by replacing the current requirements found in Sec. 180.407(d)(3) and
(g)(1)(ii) with a reference to a new paragraph (j) that would detail
the PRD test requirements. The TTMA believes this change will eliminate
confusion for testers by clarifying the requirements for opening and
reseating pressures when beginning the tests, while simultaneously
enhancing the enforcement of these requirements by creating consistency
in the testing requirements for cargo tank PRDs of the same design.
PHMSA determined that TTMA's petition merited consideration of a
rulemaking change based on the need for consistent and clear testing
requirements for PRDs on DOT specification cargo tanks, and as a
result, PHMSA received five comments in support of the proposed
revision. Girard Equipment, Inc., TTMA, Mr. Peter Weis, Betts
Industries Inc., and Dow Chemical Company commented in support of the
amendment. One anonymous commenter believed the proposed amendment is
not in the best interest of safety, stating that the revision will
allow for PRDs intended for the DOT-400 series of cargo tanks to be
installed on DOT-300 series cargo tanks, therefore opening at well over
the maximum allowable working pressure (MAWP) of the DOT-300 series.
The TTMA responded to this commenter in a follow-up comment stating
that the anonymous commenter is incorrect, further stating that the
proposed amendment keeps PRDs on upgraded DOT-300 series cargo tanks
functioning according to the requirements for DOT-400 series cargo
tanks and that this represents an improvement in safety, which is why
they are required on current construction and why provision is made for
upgrading older construction tanks. Due to the overwhelming support to
TTMA's petition and the NPRM, PHMSA is adopting the revisions to both
Sec. 180.407(d)(3) and (g)(1) as proposed to reference a new paragraph
(j), which will outline the testing requirements applicable to PRDs.
Application for Designation as a Certification Agency
An anonymous commenter stated that Sec. 107.402(f) incorrectly
cites the requirements for inspection and test marking in Sec.
180.605(k) and further suggests that Sec. 107.402(f) should cite the
pressure test procedures in Sec. 180.605(h). PHMSA disagrees,
believing instead that Sec. 107.402(f) should be revised to correctly
reference Approval of Specification UN Portable Tanks, which would be
consistent with Sec. 107.402(f)(2). Therefore, in this final rule,
PHMSA will revise Sec. 107.402(f) to reference Sec. 178.273 instead
of Sec. 180.605(k).
B. Provisions Not Adopted in This Final Rule
Based on an assessment of the proposed changes and the comments
received, PHMSA identified four provisions that we are not adopting in
this final rule: (1) The incorporation by reference into Sec. 171.7 of
the proposed edition of the Association of American Railroads (AAR)
Manual of Standards and Recommended Practices, Section C-III,
Specifications for Tank Cars, Specification M-1002 (Specifications for
Tank Cars); (2) the revision to the forbidden material requirements in
Sec. 173.21(e); (3) the odorization of cylinders and certain cargo
tanks containing liquefied petroleum gas (LPG); and (4) the revision to
the definition of ``person'' in Sec. 180.401. Below is a summary of
the amendments proposed, the comments received, and PHMSA's rationale
for not adopting these proposed amendments.
Incorporation by Reference of AAR Specifications for Tank Cars (M-1002)
The National Technology Transfer and Advancement Act of 1995 (15
U.S.C. 272) directs agencies to use voluntary consensus standards in
lieu of government-unique standards except where inconsistent with law
or otherwise impractical. Section 171.7 lists all standards
incorporated by reference into the HMR and informational materials not
requiring incorporation by reference. One particular incorporation by
reference is the AAR's Specifications for Tank Cars, October 2000
edition for various tank car design, manufacture, inspection and
testing, and qualification regulations set forth in parts 173, 179, and
180 of the HMR. As currently incorporated by reference, all sections
refer to the October 2000 edition of this document.
AAR frequently updates the specifications for tank cars; however,
PHMSA has not formally received a petition for rulemaking to revise the
HMR to reflect more current versions of the AAR Specifications for Tank
Cars.
In the NPRM, we proposed to revise the incorporation by reference
for this document to include the 2007 edition of the AAR Specifications
for Tank Cars and certain subsequent amendments. PHMSA also proposed to
revise Sec. 179.24(a)(2) to remove the reference to the December 2000
edition of this document and instead replace it with a generic
reference to the AAR Specifications for Tank Cars. Additionally, we
proposed to revise Sec. 180.503 to replace the reference to the ``AAR
Tank Car Manual'' with ``AAR Specifications for Tank Cars'' for
consistency with references to this document elsewhere in the HMR.
PHMSA also notes that the FRA had reviewed the 2007 standard and the
subsequent amendments and determined not to incorporate the 2007
standard in its totality.
PHMSA received three negative comments to this direct proposal for
incorporation by reference. The Chlorine Institute (CI) commented that
it is PHMSA's assertion that FRA does not support certain amendments of
a given chapter or appendix [of the Specifications for Tank Cars] due
to ``safety concerns,'' furthermore stating that those concerns should
be explained in the rulemaking. If FRA has determined that specific
standards or practices are unsafe, CI questions if it should be
required to comply with a different version of the M[hyphen]1002 Tank
Car Manual, per AAR requirements, as opposed to simply complying with
what is currently in the HMR. The AAR requests that the final rule
include the latest edition of the AAR Specification for Tank Cars that
was published in November 2014 and that PHMSA provide it with a list of
these ``safety concerns'' in reference to the AAR Specifications for
Tank Cars. Moving forward AAR strongly supports working together with
PHMSA and FRA on a scheduled implementation plan to evaluate and
incorporate amendments made by the AAR to the incorporation by
reference of the AAR Specifications for Tank Cars. Dow Chemical Company
had concerns with PHMSA's approach and believes the HMR should simply
incorporate by reference the most
[[Page 35492]]
current version of the AAR Specifications for Tank Cars. They go on to
state that referencing certain previous amendments of older versions of
the standards into the HMR will cause confusion and unnecessary burden.
If, as PHMSA states in the NPRM, the FRA does not support specific
current AAR standards or practices and deems them unsafe, then Dow
Chemical Company believes those ``safety concerns'' should further be
explained.
After consideration of the comments received, PHMSA in consultation
with FRA agrees with commenters and will not adopt the incorporation by
reference as proposed. PHMSA and FRA agree that the safety concerns
raised by FRA are not adequately explained and that a more current
version of the AAR Specifications for Tank Cars is available and thus
good cause reasons exist for not adopting the proposed amendment. The
FRA will continue to evaluate amendments made to the AAR Specifications
for Tank Cars and will update the effective dates for referenced
chapters or appendices, as appropriate, when such amendments are
supported by FRA. PHMSA and FRA agree with AAR that future
collaborative efforts to update both the AAR Specifications for Tank
Cars and the corresponding incorporation by reference into the HMR
would be beneficial to stakeholders.
PHMSA further notes that we received a negative joint comment from
PublicResource.org and Greenpeace regarding our general practice of
incorporating by reference. They did not comment on the substantive
merits of the proposed rule. Instead, they ask PHMSA to recognize that
it has acted illegally and arbitrarily at the NPRM stage in not making
the standards--which are integral parts of the rule--available to the
public for review without having to pay for them. They go on to state
that the unwarranted action by PHMSA places an unreasonable burden on
members of the public who wish to review the entire rule in order to
fully understand it and to make appropriate comments. PHMSA disagrees
with the basis for the joint comment as we have complied with the
requirements in 1 CFR part 51 for incorporation by reference. However,
as discussed above, we are not adopting the revision to the
incorporation by reference of the AAR Specifications for Tank Cars as
proposed.
It is noted that the editorial revisions to Sec. Sec. 179.24(a)(2)
and 180.503 are being adopted as proposed as clarifying amendments.
Prohibition of Materials in the Same Transport Vehicle
Section 173.21 outlines forbidden materials and packages, with
paragraph (e) of this section forbidding the transport of a material in
the same packaging, freight container, or overpack with another
material, that if mixed would likely cause a dangerous evolution of
heat, flammable or poisonous gases or vapors, or the production of
corrosive materials. While this prohibition prevents incidents from
occurring within a freight container, overpack, or the same container,
there is no prohibition on this type within a transport vehicle (e.g.,
a truck with single trailer).
In May 2013, PHMSA received a request for a letter of
interpretation (Ref. No. 13-0111) describing a potentially dangerous
situation whereby a company offers for transportation ``UN1908,
Chlorite Solution, Class 8, Packing Group (PG) II,'' ``UN1791,
Hypochlorite Solutions, Class 8, PG III'' and ``UN1789, Hydrochloric
Acid Solution, Class 8, PG II'' in separate intermediate bulk
containers (IBCs) in the same transport vehicle. While there are no
formal segregation requirements per Sec. 177.848 of the HMR, data
accompanying the letter indicated that in the event of co-mingling,
these materials would create chlorine dioxide gas. ``Chlorine dioxide
(not hydrate)'' is forbidden for transportation per the Sec. 172.101
HMT. Thus, the transportation of these materials in the same transport
vehicle would create a situation where the mixing of the materials
would produce a poisonous gas and highly corrosive material, which
happens to also be forbidden from transport; yet, under the current
construct of Sec. 173.21, there is no prohibition against this
transport scenario.
In the NPRM, PHMSA proposed to prohibit the transportation or
offering for transportation of materials in the same transport vehicle
(e.g., a trailer, a rail car) with another material that is likely to
cause a dangerous evolution of heat, flammable or poisonous gases or
vapors, or produce corrosive materials upon mixing for both rail and
highway transport.
PHMSA received 13 comments on the proposed amendment from AAR, ACC,
ATA, CI, COSTHA, DGAC, IME, Jones Chemical, NACD, RIPA, UPS, USWAG, and
Veolia. All of the comments strongly opposed the proposed amendment.
The commenters addressed topics related to the proposed amendment such
as the difficulty in implementing the prohibition; the impact on
shipper and carrier operations; the economic implications; and the
safety benefit, or lack thereof. An overview of these comments is
provided below, and the complete list of comments pertaining to this
amendment is available in the docket for this rulemaking.
The majority of commenters stated that carriers, offerors, and
other hazardous materials employees typically have neither sufficient
information available nor the technical expertise to make the
assessments necessary to comply with the proposed amendment. As such, a
carrier cannot be expected to identify and evaluate each individual
package consigned for carriage to determine whether the materials in
those packages would be compatible with each other in the unlikely
event they were to be unintentionally mixed. Further, shippers cannot
possibly know what other packaged materials will be transported in the
vehicle carrying their products and cannot be expected to determine
whether any of the materials onboard the vehicle, if inadvertently
mixed, would create a hazard. The DGAC commented that this prohibition
would apply not only to materials identified as hazardous materials,
but also to non-hazardous materials.
The majority of commenters stated that the proposed prohibitions
would result in increased costs as offerors and carriers would need to
further segregate hazardous materials, thus creating the need for
separate trucks to carry materials presently authorized for carriage in
a single truck. Several of the commenters indicated that this would
increase highway traffic as well as the probability of highway
accidents. Veolia commented that many of their customers generate waste
materials that would be deemed to be incompatible for shipment together
if this new restriction is adopted further stating that this would
result in the need to ship the wastes off-site for disposal using more
than one transport vehicle to accommodate the proposed restrictions.
Another commenter, NACD, notes there would be an increase in
distributor costs, as distributors would need to purchase more trucks
to increase their fleets.
Several commenters stated their belief that the segregation
provisions of Sec. 177.848 already sufficiently address the danger
associated with co-loading incompatible materials and that these
provisions have a proven and long-standing safety record. COSTHA
commented that the Sec. 177.848 segregation table clearly indicates
when certain hazard classes or divisions are known to react dangerously
and,
[[Page 35493]]
therefore, when they must be segregated. COSTHA further noted that the
segregation table was developed on the basis that the current
classification system is an adequate and appropriate manner to classify
materials. Furthermore, Veolia pointed out PHMSA's own words in letter
Ref. No. 13-0111: ``[w]e recognize the concerns that you have regarding
the transport of Chlorite and Hypochlorite Solutions with Hydrochloric
Acid in the same transport vehicle. However, we believe that the
packaging requirements for these materials mitigate the potential for
comingling and subsequent dangerous evolution of gas.''
Based on the comments received, PHMSA will not be adopting any
changes to the forbidden materials provisions specified in Sec.
173.21(e). It was not PHMSA's intent to propose an amendment that would
impose a significant operational and economic burden on the regulated
community; rather PHMSA's intention was to address a safety issue
identified through a request for a letter of interpretation. Based on
further review and the rationale presented by commenters, PHMSA
believes the current packaging and segregation requirements adequately
address the unlikely scenario of a dangerous situation caused by the
unintentional and unlikely mixing of materials during transport.
Odorization of Cylinders and Certain Cargo Tanks Containing Liquefied
Petroleum Gas (LPG)
Section 172.304a prescribes the filling requirements for cylinders
containing compressed gases. In the NPRM, PHMSA proposed to add new
Sec. 173.304a(d)(5) in addition to the proposed revised text in
Sec. Sec. 173.314(h) and 173.315(b)(1) that addresses the odorization
of LPG in rail tank car tanks and cargo tanks, respectively. We also
proposed to revise the existing Sec. 173.315(b)(1) to add a
performance standard to address the issues of ``under-odorization'' and
``odor fade.'' PHMSA received comments from the NPGA in opposition to
extending the odorization standards proposed to cylinders and revision
of the requirement to cargo tanks. They state that, while it may seem
intuitive to simply apply the requirements to these additional
containers, PHMSA was unaware of the impact this will have on retail
propane marketers further downstream in the distribution chain, and as
proposed, they believe the requirement would place an undue burden on
retail propane marketers, particularly for the more than 90 percent of
NPGA members designated as small businesses.
On June 26, 2015, PHMSA met with representatives of NPGA and their
membership, as well as the National Association of State Fire Marshalls
(NASFM) to discuss the odorization provisions in the NPRM. In this
meeting, NPGA and NASFM outlined in further detail their concerns with
the proposed requirements. The NPGA reiterated the downstream
consequences of the proposed requirement to fillers, distributors, and
sellers of cylinders and smaller cargo tanks under 3,500 gallons
capacity (previously mentioned as ``bobtails''). As stated in their
comment, NPGA provides cost information associated with the proposed
requirements, estimating that with 200,000 cylinder fillings daily,
quantitative testing requirements for cylinders would likely exceed
$480 million per year to the industry. Bobtails that experience high
turnover (three to five fills per day) would be subject to the proposed
odorant performance standard as well. These distributors of propane do
not have the odorant chemical (ethyl mercaptan) on site, nor the
trained personnel and experience to comply with the proposed
requirement. They went on to state that applying the requirement to
rail tank cars is the most effective means of addressing odorant fade
as it is the furthest upstream transportation. If a rail tank car is
effectively odorized, all movement downstream would meet the odorant
requirements and presumably not fade. The NASFM commented in the
meeting in support of NPGA on this issue. Furthermore, the NPGA claimed
that odorant fade is most likely to occur in mixed-use rail tank cars
as they are not used in ``dedicated service'' and are cleaned prior to
filling with propane. Meanwhile, bobtails and bulk storage tanks are in
``dedicated service'' so they experience less odorant fade due to being
``seasoned''--i.e., there is less absorption of odorant into the tank
walls and, thus, more odorant remains mixed with the LPG.
In the meeting, the NPGA stated that the National Fire Protection
Association (NFPA) already requires a ``sniff-test'' for odorized LPG
and provided cost information on the existing ``sniff test.'' While
this test is not in the HMR, the cost data provided by NPGA estimates
an annual total of $9 million to the industry. The NPGA cost
information, as well as the meeting notes can be found in the docket
for this rulemaking.
PHMSA recognizes the NPGA's concerns and does not intend to place
an undue economic burden on retail distributors of LPG. With an
understanding of the propane industry's supply chain, we hope to
address odorization further up the transportation stream to avoid
odorant fade or under-odorization occurring downstream. It is not our
intent to require retail distributors offering for transport or
transporting propane from their bulk storage facilities to end users in
cylinders or bobtail cargo tanks to qualitatively test odorant levels
in the LPG. Instead, our goal with the revisions adopted would be to
require this testing for larger packages of LPG (rail tank cars or
certain cargo tanks) from a refinery, gas plant, or pipeline terminal
destined for those retail distributors. While provisions requiring
odorization and measures to address odorant fade or under-odorization
for cylinders, cargo tanks, or portable tanks not originating from a
refinery, gas plant, or pipeline terminal are not being adopted in this
rule, amendments addressing rail tank cars and other point-of-origin
transportation are discussed further in the preamble.
Applicability of the Word ``person'' Sec. 180.401
In the NPRM, PHMSA proposed to revise the term ``person'' to
``hazardous materials employee or hazardous materials employer.'' The
proposed revision was an attempt to clarify that subpart E of part 180
qualification and maintenance of cargo tank requirements applies not
only to persons offering hazardous materials for transportation or
transporting a hazardous material, but also to those involved with
qualification, maintenance, or periodic testing of cargo tanks. PHMSA
received an anonymous comment pointing out that the proposed revision
is unnecessary because the definition for ``person'' in Sec. 171.8
already applies to a person that designs, manufactures, fabricates,
inspects, marks, maintains, reconditions, repairs, or tests a package,
container, or packaging component that is represented, marked,
certified, or sold as qualified for use in transporting hazardous
material in commerce. We agree with the commenter that the definition
for ``person'' in Sec. 171.8 already adequately and accurately
addresses the applicability of subpart E of part 180. Therefore, PHMSA
will not be adopting the proposed revision to Sec. 180.401.
Reference to the Manufacturer's Report Requirements in Sec.
178.65(i)(1)
In the NPRM, we proposed to revise Sec. 178.65(i)(1) to correctly
reference the manufacturer's report requirements in Sec. 178.35(g). A
final rule published July 20, 2011 [Docket No. PHMSA-2009-
[[Page 35494]]
0151 (HM-218F)] removed paragraph (h) and moved the manufacturer's
report retention requirements into paragraph (g). Although PHMSA did
not receive any comments on this proposed revision, PHMSA did identify
a letter of interpretation (Ref No. 01-0125) that noted an error in
what is referenced in Sec. 178.65(i)(1). In the letter, PHMSA agreed
that Sec. 178.65(i)(1) should include an exception from the marking
requirements provided in Sec. 178.35(f), not the manufacturer's report
requirements in paragraph (h) (and subsequently paragraph (g)), and
noted that it warranted a rulemaking change. In light of the letter of
interpretation, PHMSA believes that further review is needed to
determine the full intent of the exception provided in Sec.
178.65(i)(1). Thus, PHMSA will not be adopting the revision to Sec.
178.65(i)(1) as proposed.
C. Comments Outside the Scope of This Rulemaking
PHMSA received eighteen (18) comments that were either outside the
scope of the proposed rulemaking or not specifically addressing the
proposed regulatory changes. Mr. Adrian Mendoza generally supported
PHMSA's rulemaking efforts in the interest of public health and safety.
Mr. Aaron Adamczyk submitted a list of materials to be incorporated by
reference but did not respond directly to any provisions in the NPRM.
An anonymous commenter stated that the issue that caused the revision
proposed in Sec. Sec. 173.170 and 173.171 is also found in Sec. 173.6
for materials of trade, and the term ``motor vehicle,'' which includes
both the truck and trailer, limits the exception; the commenter further
requested that we consider changing the term ``motor vehicle'' to
``transport vehicle'' to allow the materials of trade exception to
apply to each unit. While PHMSA finds value in this comment, we did not
propose this revision and therefore will not adopt the commenter's
suggestion.
Another anonymous commenter stated that the definitions of cargo
tank in Sec. Sec. 171.8 and 178.320 do not match and further requests
revising the definition in Sec. 171.8 to be consistent with the
definition in Sec. 178.320, which includes solids and semi-solids.
This revision was also not proposed in the NPRM, and therefore, PHMSA
is not adopting the change.
The remaining fourteen (14) comments addressed our August 1, 2014,
``Enhanced Tank Car Standards and Operational Controls for High-Hazard
Flammable Trains (HM-251),'' proposed rule. That rulemaking covered
several key issues related to the safe transport of crude oil and other
flammable liquids by rail and its comment period closed on September
30, 2014 under Docket No. PHMSA-2012-0082. As these issues raised by
commenters under the docket for HM-218H were not proposed in HM-218H,
PHMSA will not address the comments in this final rule and consider the
comments as outside the scope of the rulemaking.
IV. Section-by-Section Review
Part 107
Section 107.402
Section 107.402 sets forth the application requirements for
designation as a certification agency to issue certificates and
certifications for packagings designed, manufactured, tested, or
maintained in conformance with the HMR and standards set forth in the
UN Model Regulations. This section also sets forth the application
requirements for designation as a certification agency to issue
certificates and certifications for lighters, portable tanks, multi-
element gas containers, and Division 1.4G consumer fireworks.
PHMSA is revising Sec. 107.402(d)(1)(i) to indicate that a
fireworks certification agency applicant must be a U.S. resident or,
for a non-U.S. resident, must have a designated U.S. agent
representative as specified in Sec. 105.40. The criteria for fireworks
certification agencies were added to the HMR in a final rule published
April 2, 2015 [Docket No. PHMSA-2010-0320 (HM-257); 78 FR 42457]. PHMSA
intended for Sec. 107.402(d)(1)(i) to correspond with the requirements
of Sec. 105.40, which specifies designated agents for non-residents;
however, the term ``citizen'' was inadvertently substituted for
``resident,'' thus PHMSA is revising Sec. 107.402(d)(1)(i) by
replacing the term ``citizen'' with the term ``resident.''
PHMSA is also revising Sec. 107.402(e) to require that a lighter
certification agency submit a statement to the Associate Administrator
explaining that the agency is independent of and not owned by a lighter
manufacturer, distributor, import or export company, or proprietorship.
Further, we are revising Sec. 107.402(f) to require that a portable
tank and MEGC certification agency submit a statement to the Associate
Administrator indicating that the agency is independent of and not
owned by a portable tank or MEGC manufacturer, owner, or distributor.
This language was included in Sec. 107.402 and pertained to all
certification agencies, but it was removed inadvertently as a result of
changes made to the HMR in rulemaking HM-257.
Section 107.402(f) sets forth the requirements for portable tank
and MEGC certification agencies prior to inspecting for compliance with
the HMR. PHMSA is revising Sec. 107.402(f) to reference Approval of
Specification Portable Tanks as provided in Sec. 178.273, rather than
Sec. 180.605(k). This would be consistent with Sec. 107.402(f)(2).
Section 107.807
Section 107.807 sets forth the requirements for authorizing
chemical analyses and tests for non-domestic manufacturers of DOT
specification or special permit cylinders. To maintain consistency with
requirements of other independent inspection agencies, PHMSA is
revising Sec. 107.807(b)(3) to require that the agency submit a
statement indicating that the inspection agency is independent of and
not owned by a cylinder manufacturer, owner, or distributor.
Part 171
Section 171.7
As previously stated, the National Technology Transfer and
Advancement Act of 1995 (15 U.S.C. 272) directs agencies to use
voluntary consensus standards in lieu of government-unique standards
except where inconsistent with law or otherwise impractical. Section
171.7 lists all standards incorporated by reference into the HMR and
informational materials not requiring incorporation by reference. The
informational materials not requiring incorporation by reference are
noted throughout the HMR and provide best practices and additional
safety measures that, while not mandatory, may enhance safety and
compliance. Table 1 in Sec. 171.7 lists informational materials that
are not incorporated by reference. In a final rule published on January
28, 2008 [Docket No. 2005-21812 (HM-218D); 73 FR 4699, effective
October 1, 2008], PHMSA added in Table 1 (formerly paragraph (b) of the
section) an entry for the CGA publication, CGA C-1.1, Personnel
Training and Certification Guidelines for Cylinder Requalification by
the Volumetric Expansion Method. Following the publication of HM-218D,
PHMSA received an appeal from Hydro-Test Products, Inc. (PHMSA-2005-
21812-0025) asking us to either remove the reference to CGA C-1.1 or
add examples of other training materials that may be used. Hydro-Test
noted that referencing only the CGA publication in the HMR could
suggest that other training materials are not acceptable.
[[Page 35495]]
PHMSA added CGA C-1.1 as an example of guidance material that may be
used to assist requalifiers in creating their cylinder training
procedures and recordkeeping requirements. The publication is not a
standalone tool for training persons on how to perform requalification
of cylinders using the volumetric expansion test method. To alleviate
confusion for cylinder requalifiers, PHMSA intended to remove the
reference to CGA C-1.1 in Sec. Sec. 171.7 and 180.205 in a previous
editorial final rule published on October 1, 2008 [Docket No. PHMSA-
2008-0227 (HM-244A); 73 FR 57001, effective October 1, 2008]. However,
PHMSA removed reference to the document only in Sec. 180.205(g)(6) and
inadvertently failed to remove the reference in Sec. 171.7. In this
final rule, PHMSA is amending Table 1 to Sec. 171.7 by removing the
entry for CGA C-1.1 to align the regulatory text with previous
rulemaking actions.
Additionally, as described in the Comment Discussion for petition
for rulemaking P-1605 and more fully discussed in the Section-by-
Section Review for Sec. 173.301, PHMSA is amending the HMR to
incorporate by reference CGA G-1.6-2011, Standard for Mobile Acetylene
Trailer Systems, Seventh Edition, copyright 2011.
Section 171.7(k) incorporates The AAR Manual of Standards and
Recommended Practices, Section C--Part III, Specifications for Tank
Cars, Specification M-1002, (AAR Specifications for Tank Cars),
December 2000. This standard prescribes approval requirements, general
design and test requirements, structural requirements, valves and
fittings, marking, recommended maintenance practice, and certification
of tank car facilities. In this final rule, PHMSA is amending paragraph
(k) of this section to list sections Sec. Sec. 179.24 and 180.503 that
reference this standard but were inadvertently omitted in a final rule
published June 25, 2012 [Docket No. PHMSA-2010-0018 (HM-216B); 77 FR
37961].
Section 171.22
In a May 3, 2007 final rule [Docket No. PHMSA-2005-23141 (HM-215F);
72 FR 25162], the importer responsibility requirements were
transitioned from Sec. 171.12(a) to Sec. 171.22(f). When
transitioning the requirement that a person importing a hazardous
material into the United States must provide the shipper and forwarding
agent with information required under the HMR, the shipper notification
was inadvertently omitted. As a result, only the forwarding agent is
presently required to be provided with information as to the
requirements of the HMR applicable to the particular shipment. In this
final rule, PHMSA is reinstating text in Sec. 171.22(f) to clearly
state that both the shipper and forwarding agent at the place of entry
must be provided with written information on the requirements of the
HMR applicable to the particular shipment. PHMSA received two comments
from ACA and DGAC providing general support for the amendment as
proposed.
Part 172
Section 172.101
Section 172.101 contains the HMT and explanatory text for using the
table information and each of the columns. In this final rule, PHMSA is
making a number of revisions to the Sec. 172.101 HMT: including the
special provisions listed in Column (7) and specified in Sec. 172.102;
removing the PG II designation from Column (5) of the HMT for organic
peroxides (Division 5.2), self-reactive substances (Division 4.1), and
explosives (Class 1) as requested in P-1590; and clarifying the
regulations and correct inadvertent errors. Changes to the Sec.
172.101 HMT will appear as a ``revise,'' and include changes to the
following table entries: ``Calcium nitrate, UN1454,'' ``Corrosive
liquids, flammable, n.o.s., UN2920,'' ``Fire extinguishers, UN1044,''
``Oxidizing solid, corrosive, n.o.s., UN3085,'' ``Propellant solid,
UN0501,'' ``Trinitrophenol (picric acid), wetted, with not less than 10
percent water by mass, UN3364,'' and ``Trinitrophenol, wetted with not
less than 30 percent water, by mass, UN1344.''
The entry for ``Calcium nitrate, UN1454'' is being revised to
reflect a change that was intended to be made when PHMSA published a
final rule on January 7, 2013 [Docket No. PHMSA-2012-0027 (HM-215L); 78
FR 987]. Special Provision B120 was inadvertently not assigned to the
entry for ``Calcium nitrate, UN1454'' when several other HMT entries
were revised to include it. Special Provision B120 indicates that the
material, when offered in conformance with the applicable requirements
of part 178 and general packaging requirements in part 173, may be
offered for transportation in a flexible bulk container. PHMSA is
revising the HMT to add Special Provision B120 to Column (7) for the
entry ``Calcium nitrate, UN1454.''
The entry for ``Corrosive liquids, flammable, n.o.s., UN2920'' is
being revised to harmonize the HMR with the UN Model Regulations, IMDG
Code, and the ICAO TI by means of providing limited quantity exceptions
for the PG II entry. Therefore, PHMSA is revising the entry for
``Corrosive liquids, flammable, n.o.s., UN2920, PG II'' to remove the
word ``None'' from Column (8A) of the HMT and add ``154.'' This change
will be consistent with similar PG II materials that are also provided
the limited quantity exception.
The entry for ``Fire extinguishers, UN1044'' is being revised to
eliminate reference to Special Provision 18, which is no longer in the
HMR. Special Provision 18 was removed from Sec. 172.102(c)(1) in a
January 7, 2013 final rule [Docket No. PHMSA-2009-0126 (HM-215K); 78 FR
1101] and combined into revised Sec. 173.309(a). We did not make a
conforming amendment to remove Special Provision 18 from this entry in
the HMT; thus, in this final rule, we are to revising the entry for
``Fire extinguishers, UN1044'' by deleting the special provision.
The NPRM proposed to revise the entry for ``Oxidizing solid,
corrosive, n.o.s., UN3085'' to harmonize with the UN Model Regulations,
IMDG Code, and the ICAO TI by means of providing limited quantity
exceptions for the PG II entry. However, in between the publishing of
the NPRM and this final rule, PHMSA inadvertently revised this entry as
proposed in a previous final rule [Docket No. PHMSA-2015-0103 (HM-260);
80 FR 72914]. Therefore, PHMSA will not be revising this entry in this
final rule.
PHMSA received four comments on the proposed revisions to the
UN3085 (as well as UN2920) in Column (8A). In their comments, ACA,
Veolia, and URS supported the revision of these two entries to
harmonize with UN Model Regulations, IMDG Code, and the ICAO TI. The
URS provided a list of nine (9) additional PG II entries for which a
limited quantity exception is provided under international standards
but not in the HMR and requested the same revision made to UN2920 and
UN3085 be made to these additional entries. An anonymous commenter
requested that PHMSA make the same limited quantity exception revision
to the UN3084, PG II entry. PHMSA agrees with the commenters that the
HMR is not completely in alignment with the with UN Model Regulations,
IMDG Code, and the ICAO TI limited quantity exceptions with regard to
these additional PG II entries. However, given the lack of historical
context and the need for a technical review of each entry, PHMSA will
only be revising the limited quantity exception for the entries that
have been proposed. PHMSA may consider the revision to additional
entries offered by the commenters under
[[Page 35496]]
a future rulemaking. Additionally, PHMSA encourages the commenters to
submit a petition for rulemaking in accordance with Sec. Sec. 106.95
and 106.100 for entries that they believe should also be revised.
The entry for ``Propellant, solid, UN0501'' is being revised to
eliminate a reference to a requirement that is no longer in the HMR.
Column (10B) of this entry lists vessel stowage provision 24E; however,
vessel stowage provision 24E was removed from Sec. 176.84(c)(2) when
the Research and Special Programs Administration (RSPA), PHMSA's
predecessor, published a final rule on June 21, 2001 [Docket No. RSPA-
2000-7702 (HM-215D); 66 FR 33316, effective October 1, 2001] that
revised the table of provisions applicable to vessel transportation of
Class 1 (explosive) materials. As this provision is no longer in the
HMR, PHMSA is revising the entry for ``Propellant, solid, UN0501'' to
remove vessel stowage provision 24E from Column (10B) of the HMT.
The HMT entries for ``Trinitrophenol (picric acid), wetted, with
not less than 10 percent water by mass, UN3364'' and ``Trinitrophenol,
wetted with not less than 30 percent water, by mass, UN1344'' are being
revised to harmonize the HMR with the UN Model Regulations, IMDG Code,
and the ICAO TI. Presently, Special Provision 162 is applied to UN3364
(not less than 10 percent water) and Special Provision 23 is applied to
UN1344 (not less than 30 percent water). Special Provision 162 outlines
a provision for transport of the material as Division 4.1: The material
must be packed such that at no time during transport will the
percentage of diluent fall below the percentage that is stated in the
shipping description. Special Provision 23 is similar in that it also
outlines this provision but includes an additional condition that
quantities of not more than 500 grams per package with not less than 10
percent water by mass may also be classed in Division 4.1, provided a
negative test result is obtained when tested in accordance with test
series 6(c) of the UN Manual of Tests and Criteria.
The special provisions are assigned in the reverse manner to the
trinitrophenol entries in the UN Model Regulations, IMDG Code, and the
ICAO TI. Special Provision 23 is applied to UN3364 with the lower
minimum diluent percent of water while the 500 gram limit per package
for 10 percent diluent does not apply to UN1344 with the larger minimum
diluent percentage of water (i.e., 30 percent). Thus the special
provision was incorrectly assigned in the HMR. For the entry
``Trinitrophenol (picric acid), wetted, with not less than 10 percent
water by mass, UN3364,'' we are replacing Special Provision 162 in
Column (7) of the HMT with Special Provision 23. Conversely, for the
entry ``Trinitrophenol, wetted, with not less than 30 percent water, by
mass, UN1344,'' we are replacing Special Provision 23 from Column (7)
of the HMT with Special Provision 162.
PHMSA is revising Column (8C) of the HMT for ``Asbestos, NA2212,''
``Blue asbestos (Crocidolite) or Brown asbestos (amosite, mysorite),
UN2212,'' and ``White asbestos (chrysotile, actinolite, anthophyllite,
tremolite), UN2590,'' to refer to packaging instructions in Sec.
173.216, instead of Sec. 173.240.
In a final rule published on November 23, 2015 [Docket No. PHMSA-
2015-0103 (HM-260); 80 FR 72913], PHMSA revised the HMT entry ``NA1993,
Combustible liquid, n.o.s.'' by removing special provision T4. In a
subsequent final rule published on December 21, 2015 [Docket No. PHMSA-
2011-0345 (HM-233D); 80 FR 79423] the same entry was revised by adding
Special Provision 148. In making the addition of Special Provision of
148, the previously removed Special Provision T4 was inadvertently
reinstated. This final rule corrects that error by removing Special
Provision T4 from the entry for NA1993.
In a final rule published on January 21, 2016 [Docket No. PHMSA-
2013-0042 (HM-233F); 81 FR 3635], PHMSA did the following:
Inadvertently revised the ``Corrosive liquids, n.o.s.,
UN1760'' entry by assigning it the incorrect NA prefix and inserting
Special Provision 386 to the Packing Group II and III entries. The HM-
233F final rule should have revised the ``Compounds, cleaning liquid,
NA1760'' entry by adding Special Provision 386 to the Packing Group II
and III entries. This final rule corrects those errors by removing
Special Provision 386 from the ``Corrosive liquids'' entry and adding
them to the ``Compounds, cleaning liquid'' entry, and re-assigning the
``Corrosive liquids'' entry the correct prefix of UN.
Inadvertently revised Column (10B) of the ``Coating
solution (includes surface treatments or coatings used for industrial
or other purposes such as vehicle undercoating, drum or barrel lining),
UN1139'' entry by removing the vessel stowage provision E and replacing
with the letter B. Consequently, PHMSA is restoring the letter E in
Column (10B) for this entry.
Inadvertently revised Column (8B) of the ``Printing ink,
flammable or Printing ink related material (including printing ink
thinning or reducing compound), flammable, UN1210'' entry by changing
the packaging section for Packing Group I from Sec. 173.173 to Sec.
173.201. Consequently, PHMSA is restoring Sec. 173.173 in Column (8B)
for this entry. Further, in this final rule, PHMSA is correcting the
roman and italicized text for this entry in Column (2) of the HMT.
Inadvertently revised Column (7) of ``Self-heating solid,
organic, n.o.s., UN3088'' by removing UN portable tank code T1 from the
Packing Group III entry. Consequently, PHMSA is restoring the code to
Column (7) of the HMT.
Inadvertently revised Column (10B) of the ``Potassium,
UN2257'', ``Sodium, UN1428'', and ``Water reactive solid, n.o.s.,
UN2813'' entries by removing vessel stowage provisions 13 and 148.
Consequently, PHMSA is restoring the codes to Column (10B) of the HMT
for each entry.
Section 172.102
Section 172.102 outlines special provisions that are listed in
Column (7) of the Sec. 172.101 HMT. Special Provision 136 is listed
for the entry ``Dangerous Goods in Machinery or Dangerous Goods in
Apparatus, UN3363.'' PHMSA received a request for a letter of
interpretation (Ref. No. 12-0037) that sought confirmation that a
material classed as a Class 2 gas that has packaging exceptions listed
in Column (8A) of the HMT may be described as ``Dangerous Goods in
Apparatus, UN3363.'' The requestor pointed out that the provisions in
Special Provision 136 are inconsistent: Special Provision 136 currently
states that except when approved by the Associate Administrator,
machinery or apparatus may only contain hazardous materials for which
exceptions are referenced in Column (8) of the HMT and are provided in
part 173, subpart D. Subpart D contains the definitions,
classification, packing group assignments, and exceptions for hazardous
materials other than Class 1 and Class 7. However, preparation,
packaging, and exceptions for Class 2 gases are located in subpart G of
part 173. This should be indicated in Special Provision 136 to
eliminate confusion that gases prepared in accordance with subpart G of
part 173 would not be eligible to be described as ``Dangerous Goods in
Apparatus, UN3363.'' It was not PHMSA's intention to exclude Class 2
gases from using this proper shipping name, therefore, PHMSA is
revising Special Provision 136 in Sec. 172.102 to include reference to
part 173, subpart G.
[[Page 35497]]
Section 172.201
Section 172.201 prescribes the requirements for the preparation and
retention of shipping papers. This paragraph requires that, except as
provided in Sec. 172.604(c), a shipping paper must contain an
emergency response telephone number. The reference in this paragraph to
Sec. 172.604(c) is inaccurate. The requirements in Sec. 172.604
applicable to emergency response telephone numbers were changed when
PHMSA published a final rule on October 19, 2009 [Docket No. PHMSA-
2006-26322 (HM-206F); 74 FR 53413, effective November 18, 2009]. This
rulemaking action moved the exceptions regarding the requirement to
provide an emergency response telephone number to a new paragraph (d).
PHMSA received one comment from the American Coatings Association (ACA)
in support of this change without further issue. In this final rule,
PHMSA is revising Sec. 172.201(d) to accurately reference the
exception from the emergency response telephone number requirement
found in Sec. 172.604(d).
Sections 172.301, 172.326, 172.328, and 172.330
Sections 172.301, 172.326, 172.328, and 172.330 prescribe marking
requirements for non-bulk packagings, portable tanks, cargo tanks, tank
cars, and multi-unit tank car tanks, respectively. Each of these
sections contains a paragraph (specifically, Sec. Sec. 172.301(f),
172.326(d), 172.328(e), and 172.330(c)) prescribing requirements for
packages containing unodorized LPG to be legibly marked with ``NON-
ODORIZED'' or ``NOT-ODORIZED.'' PHMSA received a request for a letter
of interpretation (Ref. No. 06-0235) requesting clarification that the
``NON-ODORIZED'' or ``NOT-ODORIZED'' mark may also appear on a package
containing odorized LPG. In the response letter, we noted that PHMSA
addressed this issue in part in a final rule published by its
predecessor agency, RSPA, on November 4, 2004 [RSPA-03-15327 (HM-206B);
69 FR 64462, effective October 1, 2006]. Final rule HM-206B changed the
hazard communication requirements applicable to certain packages
containing unodorized LPG, including the requirement to mark with
``NON-ODORIZED'' or ``NOT-ODORIZED.'' Specifically, it also clarified
that the ``NON-ODORIZED'' or ``NOT-ODORIZED'' marking may appear on a
tank car or multi-unit tank car tanks used for both unodorized and
odorized LPG. This was implemented to address the concerns expressed by
a commenter about the logistics of tracking, inspecting, and stenciling
tank cars to ensure proper marking. However, this clarification was not
extended to cylinders, cargo tanks, and portable tanks containing LPG
in that final rule. We further noted in the response letter that we
intended to revisit this issue in a future rulemaking to extend this
clarification to other packaging types that are filled with unodorized
or odorized LPG.
PHMSA received negative comments from the NASFM, the NTSB, the
IAFC, and the New Hampshire Office of the State Fire Marshall. The NTSB
disagrees with the proposed exception, citing a 2005 railroad incident
involving the release of diesel fuel from a locomotive and Safety
Recommendation R-07-4 as grounds for their dissent.\2\ The NTSB
disagrees with both the proposed exception to expand eligible packaging
types and the existing exception for tanks cars, stating that it is
concerned that the ``NON-ODORIZED'' or ``NOT-ODORIZED'' package
markings would be rendered meaningless by the proposal to allow such a
marking on a tank containing odorized LPG. It believes it is poor
policy to allow ``mislabeling'' of LPG tanks merely for logistical
convenience, further stating that while the HMR does not require
odorization in all cases, the requirement to properly mark these
packages as ``ODORIZED'' or ``NOT-ODORIZED'' based on the actual
condition of the LPG being transported (odorized or not odorized)
should be a fundamental tenet to emergency response planning and
execution involving hazardous materials in transportation. Therefore,
the NTSB urged PHMSA not to approve the proposed rule changes and
suggests that instead, PHMSA approve an acceptable means for the ``NON-
ODORIZED'' or ``NOT-ODORIZED'' marking to be temporarily covered
whenever the container is used to transport odorized LPG. PHMSA
disagrees with this comment and is puzzled as to how the incident cited
in NTSB's comment, which involved a collision of two trains and a
release of diesel fuel from locomotives, is relevant to the proposed
language from the NPRM. The allowance for the marking to remain on a
package already exists for tank cars, so PHMSA simply proposed to
extend this exception to other packaging types. We also disagree that
the marking would be rendered meaningless if allowed to remain on
odorized tanks of LPG. If the contents were to undergo odorant fade
during the course of transportation, this marking would provide an
additional level of safety. Additionally, we fail to see how extending
the requirement to existing package types is a detriment to the safety
benefit provided by that mark existing on non-odorized packages of LPG.
---------------------------------------------------------------------------
\2\ R-07-4: With the assistance of the Federal Railroad
Administration, require that railroads immediately provide to
emergency responders accurate, real-time information regarding the
identity and location of all hazardous materials on a train.
---------------------------------------------------------------------------
The NASFM, IAFC, and the New Hampshire Office of the State Fire
Marshall also provided negative comment; however, they did not comment
on the proposed exception, instead focusing on the existing regulatory
allowance for the marking to remain on tank cars and multi-unit tank
car tanks. The three commenters all stated that the allowance of the
marking to remain on odorized packages will create confusion for first
responders when looking for leaks from containers with odorized LPG.
They state that if the mark is seen on a tank that is actually
odorized, they will skip over that tank and may miss a leak. PHMSA
disagrees with the commenters and while we fully appreciate the benefit
that odorization has for leak detection in an emergency response
situation, we do not feel that it is the sole method to detect such
leaks.
Thus, PHMSA is revising Sec. Sec. 172.301(f), 172.326(d) and
172.328(e) to include the clarification that the marking may appear on
these packagings used for both unodorized and odorized LPG and to
remove the effective date of October 1, 2006. PHMSA is also removing
the effective date referenced in paragraph Sec. 172.330(c) for
consistency.
Section 172.406
Section 172.406 specifies the placement of labels on a package.
Paragraph (d) of this section prescribes requirements that labels be
printed or affixed to a background of contrasting color, or they must
have a dotted or solid line outer border. Further, Sec. 172.407(b)(2)
provides that the dotted line border on each label shown in Sec. Sec.
172.411 through 172.448 is not part of the label specification, except
when used as an alternative for the solid line outer border to meet the
requirements of Sec. 172.406(d). Based on this language, it appears
that labels with a dotted or solid line outer border are permitted only
if the surface of the package is not a contrasting color, thus causing
confusion.
In this rulemaking, we are amending Sec. 172.406(d) by expressly
authorizing the use of labels described in part 172, subpart E with a
dotted or solid line
[[Page 35498]]
outer border on a background of contrasting color. There is no
reduction in hazard communication with this revision, and it will
provide cost savings to shippers by eliminating the need to acquire and
store two types of labels (one with a border and the other without)
depending on the surface color of the package. PHMSA received one
comment from ACA providing support for this amendment as proposed.
Section 172.407
Section 172.407 contains label specifications. Paragraph (d) of
this section contains color specifications for labels including a
requirement for color tolerances according to color charts referenced
in appendix A to part 172 of the HMR. Paragraph (d)(4)(ii) states that
the color charts are on display at the Office of Hazardous Materials
Safety, Office of Hazardous Materials Standards, Room 8422, Nassif
Building, 400 Seventh Street SW., Washington, DC 20590-0001. This
address does not reflect the current address of the Office; thus PHMSA
is amending the address in Sec. 172.407(d)(4)(ii) to read Standards
and Rulemaking Division, Pipeline and Hazardous Materials Safety
Administration, U.S. Department of Transportation, 2nd Floor, East
Building, 1200 New Jersey Avenue SE., Washington, DC 20590-0001.
Section 172.514
Section 172.514 prescribes the placarding requirements and
exceptions for a bulk packaging containing a hazardous material.
Paragraph (c)(4) provides an exception for an IBC that is labeled in
accordance with part 172, subpart E, instead of placarded. IBCs that
are labeled instead of placarded are authorized to display the proper
shipping name and UN identification number in accordance with the bulk
package marking size requirements of Sec. 172.302(b)(2) in place of
the UN number on an orange panel, placard, or white square-on-point.
Section 172.302(b)(2) requires that for IBCs, markings have a width of
at least 4.0 mm (0.16 inch) and a height of at least 25 mm (one inch).
This is inconsistent with the UN Model Regulations, IMDG Code, and ICAO
TI, which all require a height of 12 mm (0.47 inch). The international
size requirement is equivalent to the non-bulk marking size requirement
provided in Sec. 172.301(a)(1). In addition, the reference to the bulk
packaging marking requirements of Sec. 172.302(b)(2) in Sec.
172.514(c)(4) conflicts with Sec. 172.336(d) identification number
marking requirements, which states that when a bulk packaging is
labeled instead of placarded in accordance with Sec. 172.514(c),
identification number markings may be displayed on the package in
accordance with the marking requirements of Sec. 172.301(a)(1).
In the NPRM, we proposed to clarify that the proper shipping name
and identification number marking size for an IBC that is labeled
instead of placarded is at least 12 mm (0.47 inch), doing so by
replacing the bulk package marking reference in Sec. 172.514(c) with
the non-bulk marking reference, specifically, Sec. 172.301(a)(1).
PHMSA received four comments from ACA, DGAC, DOW, and URS providing
support for this international harmonization action. In their comments
DGAC, DOW, and URS all correctly point out that the UN Model
Regulations, IMDG Code, and ICAO TI require a 12 mm (0.47 inch) minimum
height requirement for the identification number on an IBC that is
labeled rather than placarded, although, a minimum height for the
proper shipping name is not prescribed. The DGAC and DOW suggested
Sec. 172.514(c) be revised by removing the words ``size requirements''
from the proposed text which currently reads ``. . . the IBC may
display the proper shipping name and UN identification number markings
in accordance with the size requirements of Sec. 172.301(a)(1) . . .''
Additionally, URS suggested that Sec. 172.301(a)(1) should be revised
to clarify that the size of the proper shipping name marking is not
prescribed by the regulations.
The intent of the proposed action was to clarify that IBCs that are
labeled instead of placarded can be marked in accordance with the non-
bulk size requirements in Sec. 172.301(a)(1) consistent with
international standards. As Sec. 172.301(a)(1) does not prescribe a
size requirement for the proper shipping name, only the UN
identification number would need to meet the 12 mm requirement. In the
Sec. 172.514 preamble we inadvertently stated, ``[I]n this rulemaking,
we are proposing to clarify that the marking size requirement, for both
the proper shipping name and identification number, is at least 12 mm
(0.47 inch) for an IBC that is labeled instead of placarded.'' We agree
with the comments from DGAC, DOW, and URS; thus, in this final rule,
PHMSA is revising Sec. 172.514(c)(4) for clarity as suggested by both
DGAC and DOW. As Sec. 172.301(a)(1) does not impose a size requirement
for a proper shipping name, the removal of the words ``size
requirements'' from Sec. 172.514(c) clarifies that the 12 mm (0.47
inch) size requirement prescribed in Sec. 172.301(a)(1) applicable to
UN identification numbers does not also apply to the proper shipping
name. The reduced minimum marking size will alleviate the existing
discrepancy between Sec. Sec. 172.514(c)(4) and 172.336(d) and
decrease frustration of shipments by harmonizing with international
regulations, thus ensuring IBCs marked in accordance with these
regulations are consistent with the HMR.
Part 173
Section 173.4a
Section 173.4a prescribes the requirements for excepted quantities
of hazardous materials. The excepted quantities provisions were added
to the HMR under an international harmonization final rule published on
January 14, 2009 [Docket Nos. PHMSA-2007-0065 (HM-224D) and PHMSA-2008-
0005 (HM-215J); 74 FR 2254, effective February 13, 2009]. Excepted
quantities provisions in Sec. 173.4a are intended to be consistent
with the existing exception in the ICAO TI. Paragraph (a) states that
excepted quantities of materials other than articles transported in
accordance with this section are not subject to any additional
requirements of this subchapter except for. The language is unclear as
to whether articles (including aerosols) may use the excepted
quantities provisions. As a result, PHMSA is revising this paragraph to
clarify that articles (including aerosols) are not eligible for
excepted quantity reclassification under Sec. 173.4a, although some
aerosols are eligible to be shipped as small quantities by highway and
rail in Sec. 173.4. This will eliminate confusion as to the status of
articles (including aerosols) in the context of this exception, while
providing consistent language structure with Part 3, Chapter 5, Section
5.1 of the ICAO TI.
Section 173.24a
Section 173.24a prescribes additional general requirements for non-
bulk packages. Paragraph (c)(1)(iv) provides the quantity limits for
mixed contents packages (when multiple hazardous materials are packed
within the same package) transported by aircraft. In this rulemaking,
we are clarifying that the requirements provided in paragraph
(c)(1)(iv) do not apply to limited quantity materials packaged in
accordance with Sec. 173.27(f)(2). This change is for clarification
purposes only. Misapplication of Sec. 173.24a(c)(1)(iv) would be
duplicative and, in certain cases, would place unintended restrictions
on the net quantity of hazardous materials per package.
[[Page 35499]]
Section 173.27
Section 173.27 prescribes general requirements for the
transportation of hazardous material by aircraft. Paragraph (f)(2)
contains the provisions for limited quantities but does not expressly
address limited quantity packages of mixed contents. PHMSA received a
request for a letter of interpretation (Ref. No. 13-0094) to clarify,
for transportation by aircraft, the applicable section to reference.
Specifically, the requester asked whether Table 3 in Sec. 173.27(f)(3)
or the general provisions in Sec. 173.24a(c)(1)(iv) should be used
when determining the maximum net quantity of each inner and outer
packaging for limited quantity packages of mixed contents. In response,
we stated that, as provided in Sec. 173.27(f)(2), when a limited
quantity of a hazardous material is packaged in a combination packaging
and is intended for transportation aboard an aircraft, the inner and
outer packagings must both conform to the quantity limitations set
forth in Table 3, which provides the maximum net quantity of each inner
and outer packaging for materials authorized for transportation as a
limited quantity by aircraft. For mixed contents of limited quantities
by air, the shipper must comply with the maximum authorized net
quantity of each outer package (Column 4 of 5 in Table 3) and ensure
that the total net quantity does not exceed the lowest permitted
maximum net quantity per package as shown by hazard class or division
for the hazardous materials in the mixed contents package.
In this rulemaking, we are revising Sec. 173.27(f)(2)(i) to
clarify that the maximum net quantity for limited quantity packages of
mixed contents must conform to the quantity limitations provided in
Table 3 of Sec. 173.27(f)(3). PHMSA received one comment from UPS
providing support for this revision.
Section 173.150
Section 173.150 provides exceptions for Class 3 (flammable and
combustible liquid) hazardous materials. The requirements for
combustible liquids in bulk packagings are found in Sec.
173.150(f)(3). Although placarding under subpart F of part 172 is
specified as a requirement in Sec. 173.150(f)(3)(iv), registration
requirements of Sec. 107.601 are not included among the subject
requirements. Given that Sec. 173.150(f)(3) provides a list of subject
requirements for combustible liquids in bulk packaging, PHMSA is
revising this section through additions of a new subparagraph Sec.
173.150(f)(3)(xi) stating that the registration requirements in subpart
G of part 107 are also applicable, for bulk packagings only. PHMSA is
also revising Sec. 173.150(f)(3)(ix) and (x) for punctuation
applicable to the listing of requirements. PHMSA received one comment
from ACA providing support for the amendments as proposed.
Section 173.159
Section 173.159 prescribes requirements applicable to the
transportation of electric storage batteries containing electrolyte
acid or alkaline corrosive battery fluid (i.e., wet batteries). This
section outlines packaging requirements, exceptions for highway or rail
transport, and tests that batteries must be capable of withstanding to
be considered as non-spillable. However, there is no authorization to
transport nor are there any requirements or instructions for shippers
of damaged or leaking wet batteries on how to prepare these items for
transport. PHMSA received a request for a letter of interpretation
(Ref. No. 06-0031) to clarify whether a shipper of a damaged wet
battery may utilize the exception from full regulation provided in
Sec. 173.159(e). In response, we stated that a damaged battery may be
shipped in accordance with Sec. 173.159(e) provided: (1) It has been
drained of battery fluid to eliminate the potential for leakage during
transportation; (2) it is repaired and/or packaged in such a manner
that leakage of battery fluid is not likely to occur under conditions
normally incident to transportation; or (3) the damaged or leaking
battery is transported under the provisions of Sec. 173.3(c).
PHMSA proposed adding a new paragraph (j) to Sec. 173.159 to
address this provision. However, a final rule published January 21,
2016 [Docket No. PHMSA-2013-0042 (HM-233F); 81 FR 3635] added a
paragraph (j) to account for nickel cadmium batteries containing liquid
potassium hydroxide. Therefore, all references to the previously
proposed paragraph (j) will be to the new paragraph (k).
PHMSA received positive feedback from commenters with the ATA, the
UPS, the USWAG, and Veolia voicing general support for this amendment.
Veolia requested that ``cargo vessel'' be added as a mode of
transportation; however, as this was not proposed and that inclusion
would need an analysis from both PHMSA and the USCG, and we will not be
authorizing vessel transportation in this final rule.
The Battery Council International (BCI) also commented on this
provision. While they voiced strong support for the creation of a new
paragraph to address damaged wet batteries, they had concerns that the
proposed regulatory text was unclear, did not take into account the
industry standard, and may inadvertently eliminate existing exceptions
for wet batteries. To supplement their comments, a meeting was
requested by representatives of BCI with PHMSA to clarify their
comments. Notes from that August 11 meeting can be found in the docket
for this rulemaking. The BCI's primary concern is that a different
packaging method referenced in previous PHMSA letters of interpretation
(Ref. Nos. 09-0227 and 06-0062) that utilizes leak-proof packaging in
other than an intermediate/outer configuration (i.e., single
polyethylene bag) is absent from paragraph (j). BCI asserts that the
single polyethylene bag method is sufficient to prevent leakage of the
battery acid during transportation and that changing this standard
industry practice will be highly disruptive, costly, and likely to
result in considerable confusion. During the meeting, it emphasized
that this was the predominant method of transporting damaged wet
batteries by a vast majority of industry.
PHMSA agrees with BCI's concerns and it was not our intent to undo
progress made to address safety concerns by industry and PHMSA in the
past by not allowing for this packaging configuration. Therefore, we
are amending paragraph (k) (i.e., previously proposed paragraph (j)) to
allow for this packing method. PHMSA believes that public safety would
be better served by allowing the use of a method that is known and
widely used by industry, that has a strong safety record for
transporting damaged wet batteries, and on which affected hazmat
employees are trained. The BCI further points out confusion in the
proposed regulatory text in paragraphs (j)(2) and (3), stating that it
is unclear how a shipper could comply with the packaging requirement in
Sec. 173.159(j)(2) without also complying with Sec. 173.159(j)(3).
PHMSA agrees with this comment; although, paragraphs (j)(2) and (3) are
intended to be used in tandem, they currently appear to be separate
conditions for transport. Therefore, we are amending the regulatory
text to consolidate the previously proposed (j)(2) and (3) into one
paragraph, now (k)(2). Lastly, BCI requests that clarification be added
to ensure that there is no confusion that the batteries shipped under
this paragraph are still eligible to be shipped using the exception
found in Sec. 173.159(e). PHMSA agrees. It was never our intent to
prohibit the use of this exception, and it was an oversight
[[Page 35500]]
in the NPRM not to specify this. Therefore, we are including a
provision to clarify the eligibility of damaged wet batteries for
exception under paragraph (e) when transported in accordance with Sec.
173.159(k).
PHMSA is adding a new paragraph (k) in Sec. 173.159 to address the
need for provisions that allow shippers to prepare for transport and
offer into transportation damaged wet electric storage batteries for
purposes of recycling. Note that in addition to the conditions listed
in paragraph (k), damaged wet electric storage batteries must also meet
requirements of Sec. 173.159(a).
PHMSA is reinserting language into Sec. 173.159(e)(4) of the HMR
indicating that the transport vehicle may not carry material shipped by
any person other than the shipper of the batteries. This language was
inadvertently deleted from the HMR when PHMSA published a final rule
titled ``Hazardous Materials: Reverse Logistics'' under Docket HM-253
(81 FR 18527; March 31, 2016). As revised by HM-253, Sec.
173.159(e)(4) now states that a carrier may accept shipments of
batteries from multiple locations for the purpose of consolidating
shipments of batteries for recycling, which creates confusion in the
context of the section. The intent of the HM-253 final rule was to
allow carriers to consolidate shipments of batteries from multiple
locations for the purpose of recycling. To correct this inadvertent
deletion, in this final rule we are revising Sec. 173.159(e)(4) by
retaining the previous text and providing a clear exception when
batteries are consolidated for recycling.
Section 173.166
Section 173.166 prescribes requirements applicable to the
transportation of safety devices. In a final rule published on July 30,
2013 [Docket No. PHMSA-2010-0201 (HM-254); 78 FR 45880], PHMSA revised
the requirements applicable to these materials. Among the changes made
was the adoption of Special Permit DOT-SP 12332 into the HMR. This
special permit excepted Class 9 air bag inflators, air bag modules, or
seat-belt pretensioners assigned to UN3268 from the requirement to
provide the EX number (i.e., the approval number) on the shipping
paper.
Under Sec. 173.166, paragraph (e)(6) authorizes packaging
alternatives for air bag inflators, air bag modules, and seat-belt
pretensioners that have been removed from, or were intended to be used
in, a motor vehicle, as well as those devices that meet the
requirements for use in the United States and are being transported to
recycling or waste disposal facilities. When adopted in HM-254, a
provision in Sec. 173.166(e)(6) stated ``for domestic transportation
by highway,'' thereby limiting the use of this exception to ground
transport, yet DOT-SP 12332 specifically permitted transport by ``cargo
vessel'' as an authorized mode of transportation. For greater
consistency with the special permit language adopted in HM-254, PHMSA
is revising paragraph (e)(6) to add the words ``or cargo vessel,'' and
as a result, PHMSA received one comment from Veolia providing support
for this revision. Veolia noted that this revision will remove the
administrative burden from both PHMSA and the Special Permit holders
necessary for maintaining the special permit.
Sections 173.170 and 173.171
Sections 173.170 and 173.171 prescribe exceptions for the
transportation of black powder for small arms classed as a Division 1.1
explosive and the transportation of smokeless powder for small arms
classed as a Division 1.3 or Division 1.4 explosive. These exceptions
permit these materials to be reclassed as Division 4.1 flammable solid
material for domestic transportation. In both sections, the total
quantity of black or smokeless powder for small arms is limited to 45.4
kg (100 pounds) net mass in a motor vehicle (other modes are authorized
as well). PHMSA believes the exception should be updated to account for
modern highway transportation. Currently, the HMR defines ``motor
vehicle'' in Sec. 171.8 to include a vehicle, machine, tractor,
trailer, or semitrailer, or any combination thereof. The use of the
term in this exception limits a carrier with multiple trailers to 100
pounds total of black or smokeless powder, reclassed as Division 4.1.
Carriers who commonly transport double- or triple-trailer loads by
highway may find it difficult to ensure that each trailer contains an
amount of black or smokeless powder, reclassed as Division 4.1 that
would keep the total quantity in all trailers under 100 pounds.
PHMSA believes the term ``motor vehicle'' should be replaced with
``transport vehicle'' in the context of this exception and that doing
so will not decrease the level of safety for the transport of these
materials. The term ``transport vehicle'' is defined in Sec. 171.8 as
a cargo-carrying vehicle, such as an automobile, van, tractor, truck,
semitrailer, tank car, or rail car, used for the transportation of
cargo by any mode. Each cargo-carrying body (a trailer, a rail car,
etc.) is a separate transport vehicle. Changing the term ``motor
vehicle'' to ``transport vehicle'' would reflect a consistency in the
ability to use exceptions for black or smokeless powder with the other
modes, such as rail and vessel, whereby each rail car or freight
container is permitted to have 100 pounds total.
In the NPRM, PHMSA solicited comment from stakeholders on this
issue and requested any available data relating to incidents involving
transport of black or smokeless powder for small arms reclassed as
Division 4.1 by motor vehicle. PHMSA received four comments from ATA,
DGAC, SAAMI, and UPS in support of this revision. The SAAMI, noted,,
``[w]e are aware of no incidents involving transporting black or
smokeless powder for small arms reclassed as Division 4.1 by motor
vehicle. These products are subject to a testing regime to ensure that
they meet the rigid requirements for transport as a flammable solid.''
Thus, in this final rule, PHMSA is revising Sec. Sec. 173.170 and
173.171 as proposed in the January 23, 2015 NPRM to replace the term
``motor vehicle'' with ``transport vehicle.''
Section 173.199
Section 173.199 prescribes the packaging requirements for Category
B infectious substances. Paragraph (a)(4) of this section requires that
the packaging be capable of successfully passing the drop test in Sec.
178.609(d) and the steel rod impact test in Sec. 178.609(h) at a drop
height of at least 1.2 meters (3.9 feet).
PHMSA received a request for a letter of interpretation (Ref. No.
07-0018) regarding the test requirements in Sec. 173.199(a)(4). The
request pointed out that in the preamble to the final rule published on
June 2, 2006 [Docket No. PHMSA-2004-16895 (HM-226A); 71 FR 32244]
states that Category B packagings must be capable of passing a drop
test, but need not be capable of passing a puncture or other
performance test. The requester asked if the regulatory text requiring
the steel rod impact test for this packaging was an error.
As we clarified in our response, PHMSA did not intend to require
the steel rod impact test in Sec. 178.609(h) for a packaging used to
transport a Category B infectious substance. Therefore, in this
rulemaking, we are revising the provisions in Sec. 173.199(a)(4) by
removing the reference to the steel rod impact test in Sec.
178.609(h).
Section 173.216
Section 173.216 establishes the transportation requirements for
asbestos. Paragraph (c) of this section
[[Page 35501]]
provides packaging requirements for asbestos including both ``bulk''
and ``non-bulk'' packaging options.
PHMSA received a request for a letter of interpretation (Ref. No.
11-0169) regarding the applicability of bulk and non-bulk packaging
instructions for asbestos. The letter expressed confusion regarding
whether Sec. 173.216 should apply to both ``bulk'' and ``non-bulk''
packages of asbestos, because as the requester noted in the letter, the
Sec. 172.101 HMT entry for ``Asbestos,'' NA2212 refers to packaging
instructions specified in Sec. 173.216 for non-bulk packaging
requirements and Sec. 173.240 for bulk packaging requirements. It was
also noted in the letter that some of the packaging options specified
in Sec. 173.216 are considered bulk packagings.
PHMSA acknowledged that some of the packaging options provided in
Sec. 173.216(c) meet the bulk packaging definition specified in Sec.
171.8 and, therefore, would be considered a bulk packaging for
transportation purposes. In this rulemaking, we are revising the bulk
packaging section reference in Column (8C) of the HMT to add a
reference to ``216'' for the table entries associated with the
following identification numbers: NA2212, UN2212, and UN2590. This
revision will: (1) Eliminate the confusion pertaining to authorized
bulk packaging specifications contained in a section previously only
referenced in the authorized non-bulk Column (8B) of HMT and (2) allow
for the continued use of bulk packages in Sec. 173.240.
Section 173.225
Section 173.225 contains the packaging requirements and other
provisions applicable to the transportation of organic peroxides.
Paragraph (d) of this section contains the Packing Method table, which
provides packagings authorized for organic peroxides and the maximum
quantity permitted in each package or packaging. The table is missing
pertinent information, so PHMSA is revising the table to add a
reference to Note 1 for OP2, which states that if two values are given,
the first applies to the maximum net mass per inner packaging and the
second to the maximum net mass of the complete package. Additionally,
PHMSA is revising the maximum quantity for solids and combination
packagings (liquid and solid) for OP4 to read as ``5/25'' kg instead of
only ``5.''
Section 173.301
Section 173.301 applies to general requirements for shipment of
compressed gases and other hazardous materials in cylinders, UN
pressure receptacles, and spherical pressure vessels. Paragraph (g) of
this section describes the requirements to manifold cylinders in
transportation. A manifold system is a single pipe or chamber connected
to a group of cylinders, which allows for a single point of loading and
unloading.
Incidents investigated by the NTSB have highlighted potential risks
when transporting manifolded acetylene trailers.\3\ These incidents
included overturned vehicles and two unloading releases. As a result of
the impact caused by ejection of the cylinders from the vehicle during
overturn incidents, cylinders have shown signs of broken valves, burst
heads, burst walls, as well as bulging and denting of the walls. The
impact resulting from the ejection of the cylinders from the vehicle
also can cause the valves to break, which may ignite the acetylene. The
NTSB's investigation also concluded that the unloading sequence is
occasionally done out of order from what is specified in the standard
operating procedures and that this can be a contributing factor to
incidents.
---------------------------------------------------------------------------
\3\ https://www.ntsb.gov/doclib/safetystudies/SIR0901.pdf.
---------------------------------------------------------------------------
The NTSB has issued two Safety Recommendations \4\ to PHMSA based
on recent incidents involving manifolded acetylene trailers:
---------------------------------------------------------------------------
\4\ http://phmsa.dot.gov/staticfiles/PHMSA/DownloadableFiles/Files/NTSB%20Files/H_09_1_2_Original.pdf.
H-09-01: Modify 49 CFR 173.301 to clearly require (1) that
cylinders be securely mounted on mobile acetylene trailers and other
trailers with manifolded cylinders to reduce the likelihood of
cylinders being ejected during an accident and (2) that the cylinder
valves, piping, and fittings be protected from multidirectional
impact forces that are likely to occur during highway accidents,
including rollovers.
H-09-02: Require fail-safe equipment that ensures that operators
of mobile acetylene trailers can perform unloading procedures only
correctly and in sequence.
Given the results of the NTSB investigations, as well as the
associated safety risks of mobile acetylene trailer overturns and
unloading operations, PHMSA proposed in the NPRM to incorporate by
reference in Sec. 171.7 of the HMR the CGA G-1.6-2011, Standard for
Mobile Acetylene Trailer Systems, Seventh Edition, copyright 2011. CGA
G-1.6 would serve to address the NTSB Safety Recommendations specific
to mobile acetylene trailers. This pamphlet was updated by the CGA with
input from both PHMSA and the industry to address cylinder securement
under accident conditions, valve protection from multidirectional
impact forces, and unloading procedures specific to mobile acetylene
trailers.
Specifically, PHMSA proposed to incorporate the CGA pamphlet into
Sec. 171.7 and to revise Sec. 173.301(g)(1)(iii) to indicate that
mobile acetylene trailers must be maintained, operated, and transported
in accordance with CGA Pamphlet G-1.6. In addition, PHMSA sought
specific comment on the inclusion of CGA Technical Bulletin (TB) TB-25
to address structural integrity requirements. PHMSA also proposed to
revise Sec. 177.840 by adding paragraph (a)(3) to state that cylinders
containing acetylene and manifolded as part of a mobile acetylene
trailer system must be transported in accordance with Sec. 173.301(g)
to ensure that this requirement is addressed in the carriage by highway
portion of the HMR.
PHMSA received two comments on this provision. The CGA, who
petitioned to incorporate by reference CGA Pamphlet G-1.6, stated
continued support for the adoption of this provision. Additionally,
they comment that TB-25 ought not to be included in the adopted
regulations, stating that it would be incorrectly applied. TB-25
addresses tubes that are mounted horizontally on a trailer chassis
whereas acetylene cylinders are required to be mounted vertically with
individual valve protection. Thus, while tubes are permanently mounted
onto a trailer chassis, acetylene cylinders are not permanently
attached to the trailer to allow for periodic maintenance (i.e.,
resolventing).
In its comment, the NTSB agrees with PHMSA's intent to address
mobile acetylene trailers but states that CGA Pamphlet G-1.6 does not
fully address accident impact protection from multidirectional forces
that are likely to be encountered during highway accidents, including
rollover. Additionally, they believe TB-25 should be included to
address manifolded acetylene cylinders and state that a revision to TB-
25 to include vertically-mounted, manifolded cylinders would provide a
standard for accurate and verifiable performance testing, analytical
methods, or a combination thereof, to prove the adequacy of mobile
acetylene trailer designs in both normal operation and accident
conditions. The NTSB also disagrees with PHMSA that the proposed
changes address cylinder securement, vehicle accident impact, or
rollover protection as recommended in Safety Recommendation H-09-01.
Lastly, it states that CGA Pamphlet G-1.6 does not mandate operator
[[Page 35502]]
equipment that would require them to perform unloading procedures in
the correct sequence and that it only requires that instructions are
readily available to the operator.
PHMSA appreciates both CGA and NTSB's comments on this provision.
We recognize NTSB's concerns regarding the nature of its
recommendations and what was proposed in the NPRM. Its comments
demonstrate that further examination of this issue regarding
performance in accident conditions is necessary. While we cannot adopt
additional provisions at this time as they are beyond the scope of this
rulemaking, we will work with both the NTSB and the CGA to address
remaining concerns and additional action may be taken in a future
rulemaking. However, at this time PHMSA is adopting as proposed the
incorporation by reference of CGA Pamphlet G-1.6.
Section 173.306
Section 173.306 provides exceptions from the HMR for compressed
gases, including aerosols, when transported in limited quantities. In a
final rule published May 14, 2010 [Docket No. PHMSA-2009-0289 (HM-
233A); 75 FR 27205], PHMSA added a new paragraph (k) to Sec. 173.306
adopting provisions from DOT-SP 12842. These provisions authorized an
increase in gross weight per package for the purpose of packaging
discarded empty, partially used, and full aerosol containers to be
transported to a recycling or disposal facility.
PHMSA received a request for a letter of interpretation (Ref. No.
12-0004) seeking confirmation that aerosols shipped for disposal or
recycling in compliance with Sec. 173.306(k) are permitted the same
exceptions (i.e., the marking and labeling requirements of part 172,
subparts D and E, respectively, and shipping paper requirements, unless
it is a hazardous waste or hazardous substance, of part 172, subpart C)
granted under Sec. Sec. 173.306(i) and 173.156(b) without being
reclassified as an ORM-D material. The requester also pointed out that
under DOT-SP 12842, aerosols shipped for disposal or recycling were
excepted from the marking, labeling, and shipping paper requirements,
unless they were considered a hazardous waste or hazardous substance,
without being reclassified as an ORM-D material.
In response to the NPRM, PHMSA received three comments on this
proposed change. Two commenters, the USWAG and Veolia voiced general
support for the revision. However, both Veolia and ACA noted a mistake
in the preamble language of the NPRM and believe the applicable marking
section referenced in the discussion was in error and should be Sec.
172.315(a)--for modes other than air transport, not paragraph (b).
Though, Veolia does note that the proposed revised text included by
PHMSA in Sec. 173.306(k)(3) is correct by referencing Sec.
172.315(a). PHMSA appreciates the comment from Veolia and agrees that
they are correct. Additionally, in its comment, ACA questions the need
for the proposed marking requirement in Sec. 173.306(k)(4) requiring
that limited quantity packages containing aerosols for recycling or
disposal conforming to the provisions of paragraph (a)(3), (a)(5), or
(b)(1) must also be marked ``INSIDE CONTAINERS COMPLY WITH PRESCRIBED
REGULATIONS'' in addition to marking in accordance with Sec.
172.315(a). The ACA commented that the ``INSIDE CONTAINERS COMPLY WITH
PRESCRIBED REGULATIONS'' marking is explicitly not required by Sec.
173.306(i) and therefore an original (not for recycling or disposal)
shipment of aerosols meeting the requirements of a limited quantity is
not required to be marked ``INSIDE CONTAINERS COMPLY WITH PRESCRIBED
REGULATIONS''. The ACA contends that when an aerosol is ready for
disposal or recycling it is presumably empty or less than full and that
the risk is lower, and as such, it questions the need for this
additional marking. The ACA commented that this situation is somewhat
confusing and will likely lead to mistakes and in addition, will
require shippers of aerosols to stock two different boxes or a roll of
labels for the disposal or recycling shipments, incurring additional
costs for very low-risk commodities.
PHMSA agrees that the proposed marking of packages with ``INSIDE
CONTAINERS COMPLY WITH PRESCRIBED REGULATIONS'' is not necessary, as
the presence of a Sec. 172.315(a) limited quantity mark on a package
prepared in accordance with Sec. 172.306(k) sufficiently communicates
conformance with applicable requirements, and although PHMSA does not
necessarily agree that the risk of empty or partially full aerosols is
lower due to the much larger quantity authorized per package (i.e., 500
kg gross) compared to the standard limitation of 30 kg gross, we
believe the safety concern of the larger quantity is offset by the
conditions of the exception in Sec. 172.306(k), specifically,
protecting or removing the valve stem of the aerosols and limiting
carriage to private or contract carriers, or under exclusive use
service by common carriers. The former protects against the release of
contents and while the latter prevents introduction into common
transportation channels where transport personnel do not have as much
expertise and knowledge of the package and its contents. Therefore, in
this rulemaking, we are revising Sec. 173.306(k) by clarifying that
aerosols shipped for recycling or disposal by motor vehicle, under the
specific conditions provided in Sec. 173.306(k), are afforded the
applicable exceptions provided for ORM-D materials granted under
Sec. Sec. 173.306(i) and 173.156(b). In addition, Sec. 173.306(k)
packages must be marked in accordance with Sec. 172.315(a).
Sections 173.314(h) and 173.315(b)(1)
Section 173.314 establishes requirements for compressed gases in
tank cars and multi-unit tank cars, and Sec. 173.315 establishes
requirements for compressed gases in cargo tanks and portable tanks.
PHMSA is aware of several incidents possibly attributed to either the
under-odorization or odorant fade of LPG. Although not transportation
related, most notable of these incidents is one that happened in
Norfolk, MA on July 30, 2010, where an explosion occurred at a
residential condominium complex that was under construction. Emergency
responders from 21 cities and towns deployed personnel to the accident
site. The accident resulted in seven injuries and one fatality.
The subsequent investigation raised questions as to whether there
was a sufficient level of odorant in the LPG contained in the on-site
storage tanks. In accordance with Federal and State laws and
regulations, LPG intended for use by non-industrial entities is
generally required to be odorized, or stenched, to enable the detection
of any unintended release or leak of the gas. LPG is highly flammable,
and is dangerous to inhale in large quantities; thus the addition of an
odorant is a safety precaution that helps warn those in the area that a
release of gas has occurred. In the Norfolk incident, there was no
noticeable evidence of odorant that would indicate a leaking. PHMSA has
consulted with stakeholders from industry, fire fighter associations,
and other regulatory agencies in order to better understand the root
cause of incidents like the one in Norfolk. Although additional
research may be necessary in order to come to more definitive
conclusions, PHMSA has identified the following situations in which the
risks of under-odorization or odorant fade are more likely to occur:
[[Page 35503]]
Injection Process: On December 13, 2012, PHMSA met with
representatives from the NPGA to gain a better understanding of the LPG
odorization process. During this meeting, representatives from the NPGA
stated that the most common method for the odorization of LPG is
through an automated system. However, the NPGA also noted there are
situations where the odorization process is manually performed.
Preliminary investigations into the Norfolk, MA incident suggest that
the lack of sufficient odorization rendered the LPG undetectable when
the on-site storage tank began to leak. In situations where the
injection process is not fully automated, the potential for human error
may increase the possibility of under-odorization. We believe that the
insufficient level of odorant in the LPG contained in the on-site
storage tank involved in the Norfolk, MA incident was likely a major
contributing factor in limiting the ability of on-site personnel to
readily detect the leak.
New Tanks or Freshly Cleaned Tanks: During our meetings with
various stakeholders, several indicated that a phenomenon known as
``odor fade'' may be a problem when new or recently cleaned tanks are
used. New or recently cleaned tanks may absorb the odorant into the
metal shell of these tanks leading to an ``odorant fade,'' thus
limiting the effectiveness of the remaining odorant in the LPG.
Odorization Standards: The odorization of LPG is addressed by
Federal and State laws and regulations, as well as by generally
accepted industry standards and practices. When offered and transported
in commerce, the HMR specifies that all LPG in cargo and portable tanks
be effectively odorized using either 1.0 pound of ethyl mercaptan, 1.0
pound of thiopane, or 1.4 pounds of amyl mercaptan per 10,000 gallons
of LPG, in the event of an unintended release or leak to indicate the
presence of gas. The HMR does not, however, require LPG to be odorized
if odorization would be harmful in the use or further processing of the
LPG, or if odorization will serve no useful purpose as a warning agent
in such use or further processing. Essentially, this exception applies
to LPG being transported to industrial end-users.
In response to the NPRM, PHMSA received comments from the
Massachusetts Department of Fire Services, the NASFM, the NTSB, the
IAFC, the NPGA, Trammo Inc., and the New Hampshire Office of the State
Fire Marshall on the proposed odorization requirements. All of the
commenters supported the development of an odorization standard for
rail tank cars as it exists for cargo tanks and portable tanks.
Additionally, support for qualitative testing to address under-
odorization or odorant fade was voiced.
The Massachusetts Department of Fire Services generally support
PHMSA's proposal to address odorization of LPG in both cylinders and
rail cars, as well as the creation of a performance standard to address
issues of under-odorization and odorant fade of LPG in transportation.
They believe that the proposals could be strengthened in two ways: (1)
Mandate qualitative testing equivalent to the Code of Massachusetts
Regulations, which specifies the tests that can be used to satisfy this
requirement; and (2) mandate recordkeeping requirements that can be
made available upon request. Records should include: The process of
odorization, testing and test results, and if necessary, remediation by
injection of additional odorant. The odorization in cylinders is not
being adopted as proposed. While PHMSA appreciates the prescriptive
additional requirements for odorization offered in the comment from the
Massachusetts Department of Fire Services we disagree with specifying
the tests that can be used and requiring recordkeeping. These measures
were not proposed in the NPRM and PHMSA sees specifying the tests as a
limiting factor to addressing odorization qualitative testing. While we
do not take issue with using the tests outlined in the Code of
Massachusetts Regulations, we are not prescribing specific tests. In
addition, the requirement for recordkeeping was not proposed in the
NPRM, so obligatory paperwork burdens were not accounted for: PHMSA is
required by Federal law to reduce the paperwork burdens it imposes on
private citizens and businesses. Accordingly, we do not agree that the
safety benefits achieved by requiring recordkeeping are justified.
These comments by the Massachusetts Department of Fire Services were
echoed by the NASFM, the IAFC, and the New Hampshire Office of the
State Fire Marshall.
As discussed in the section referencing the Provisions Not Adopted
in This Final Rule, the NPGA opposed an odorization testing requirement
for cylinders and cargo tanks. Although PHMSA disagrees with NPGA that
cargo tanks should be excluded from the requirements to address odorant
fade or under-odorization, we agree with its comment that it should be
addressed ``upstream'' in transportation. Therefore, we are only
applying the revised text in Sec. 173.315(b)(1) to cargo tanks and
portable tanks being offered for transport from a refinery, gas plant,
or pipeline terminal.
The NPGA also provided suggestions to improve the proposed Sec.
173.314(h) language. It suggests deleting the references to thiophane
and amyl mercaptan as these materials are no longer used as odorant in
LPG. PHMSA agrees with this comment and will remove those references.
Due to universal support by commenters for requiring an odorant
performance standard as well as measures to address odorant fade and
under-odorization in rail tank car tanks, we are adopting new Sec.
173.314(h) provisions with minor changes.
Trammo Inc. generally supported the proposed changes, but expressed
concern about the odorization requirements regarding exporting propane.
They note that odorized propane cannot be shipped internationally
because it may be sold for industrial purposes for which odorization
may be harmful, and that a small specialized fleet of refrigerated gas
carriers refuse to carry odorized products because of persistent cargo
residue and contamination. Trammo Inc. notes that receiving odorized
propane would have negative consequences for the company and its
customers. PHMSA notes these concerns; however, PHMSA points out that
Sec. Sec. 173.314(h) and 173.315(b)(1) provide an exception that
addresses this scenario indicating that odorization is not required if
harmful in the use or further processing of the liquefied petroleum gas
or if odorization will serve no useful purpose as a warning agent in
such use or further processing. This exception would apply to the
exportation and further distribution of liquefied propane gas
internationally if it cannot be offered as odorized.
Part 175
Sections 175.1 and 175.9
Section 175.1 describes the purpose, scope, and applicability of
part 175 to air operations, specifically, the transportation of
hazardous materials in commerce by air. Section 175.9 provides
exceptions from regulation under the HMR for certain special aircraft
operations. Specifically, paragraph (b)(4) of Sec. 175.9 excepts
hazardous materials carried and used during dedicated air ambulance,
firefighting, or search and rescue operations. To clarify that these
operations are not subject to the HMR when in compliance with
applicable Federal Aviation Regulations (FAR; 14 CFR) and any
additional Federal Aviation Administration (FAA)
[[Page 35504]]
requirements, PHMSA is adding a new paragraph (d) in Sec. 175.1
stating that the HMR does not apply to dedicated air ambulance,
firefighting, or search and rescue operations. This will eliminate any
confusion that these air operations would otherwise be subject to
requirements in the HMR (e.g., passenger notification requirements).
PHMSA is also removing Sec. 175.9(b)(4) for consistency.
As with other conditional exceptions to the HMR, non-compliance
with the FAR could subject operators to enforcement under the HMR, but
PHMSA does not anticipate any adverse safety consequences with this
proposed revision due to the existing training requirements in the FAR
on the proper handling and stowage of hazardous materials carried
onboard aircraft.
The FAA and PHMSA recognize that certain operators do not solely
utilize their aircraft for purposes under Sec. 175.9(b)(4). Normal
transport operations (i.e., the transport of passengers or cargo not
required for performance of, or associated with, the specialized
emergency function) would continue to be subject to the HMR. However,
staging operations and other operations related to dedicated air
ambulance, firefighting, or search and rescue operations are intended
to be excepted from the HMR when in compliance with the FAR. We note
the following definitions in FAA Order 8900.1 (Vol. 3, Chapter 14,
Section 1, 3-529(C)):
(1) Firefighting. This term includes the drop of fire
retardants, water, and smoke jumpers. It also includes the transport
of firefighters and equipment to a fire or to a base camp from which
they would be dispersed to conduct the firefighting activities.
(2) Search and Rescue. Search and rescue is a term of art
meaning aircraft operations that are flown to locate people who
cannot be located from the ground. The term includes operations
where the aircraft is indispensable to the search, or is the only
feasible means of reaching the victim. Victims would be considered
to be ``associated with'' the search and rescue operation. The term
``search and rescue'' does not include routine medical evacuation of
persons due to traffic accidents and other similar incidents.
Air ambulance operators are required by the FAR to utilize either
Operational Specification (OpSpec) A021 (Helicopter Emergency Medical
Services (HEMS) Operations) or A024 (Air Ambulance Operations--
Airplane) and must obtain and adhere to the appropriate OpSpec to be
excepted from the HMR.
Section 175.8
Section 175.8 provides exceptions from certain regulations for air
carrier operator equipment and items of replacement. Paragraph (b)(1)
provides that oxygen, or any hazardous material used for the generation
of oxygen, for medical use by a passenger, which is furnished by the
aircraft operator in accordance with certain FAR (14 CFR) requirements
is not subject to the requirements of the HMR. The provisions of the
FAR, at Sec. 125.219, Oxygen for medical use by passengers, was
inadvertently left out of paragraph (b)(1). In this rulemaking, we are
revising paragraph (b)(1) by adding the appropriate FAR, part 125
citation.
Section 175.10
Section 175.10 provides exceptions for passengers, crewmembers, and
air operators. Paragraph (a) of this section lists a number of
hazardous materials that are permitted for carriage by passengers or
crewmembers provided the requirements of Sec. Sec. 171.15 and 171.16
and the conditions of this section are met. PHMSA is proposing
revisions to some of these provisions to promote clarity.
In paragraph (a)(6), hair curlers (curling irons) containing a
hydrocarbon gas, such as butane, and carried in carry-on or checked
baggage, are excepted from the requirements of the HMR. However, gas
refills for such curlers are not permitted in carry-on or checked
baggage. In this final rule, PHMSA is prohibiting such hair curlers in
checked baggage due to the risk posed by flammable gases in an
inaccessible compartment on a passenger-carrying aircraft. Flammable
gases will burn if mixed with an appropriate amount of air and confined
burning of a flammable gas can lead to detonation. As a result, we
remain concerned with the flammability hazard posed by butane and other
flammable gases and the ability of such gases to propagate or
contribute to a fire in the cargo compartment of an aircraft. This
concern is particularly relevant to carriage in checked baggage, where
damage to the curling iron and the subsequent release of a flammable
gas may occur if the baggage is mishandled or the article itself is
compromised.
Because of the risks posed by flammable gas, a number of safety
requirements apply to cargo shipments of flammable gas on passenger-
carrying aircraft. Most Division 2.1 flammable gas substances and
articles are generally forbidden from transportation as cargo aboard
passenger-carrying aircraft, and PHMSA's prohibition of the carriage of
butane-powered curling irons in checked baggage is consistent with this
provision. In the area of aviation safety, where the high volume of
travel and the catastrophic consequences of failure lead to a very low
tolerance for risk, we firmly believe the known risks of flammable gas
are sufficient basis for our decision. In the NPRM, we solicited public
comment on any impact our proposed action may impose upon passengers,
crew members, and air operators; however, PHMSA did not receive any
comments.
In paragraph (a)(22) of this section, non-infectious specimens
transported in accordance with Sec. 173.4b(b) (de minimus quantities)
are permitted for carriage by passengers or crewmembers. PHMSA is
clarifying this exception to include the phrase ``in preservative
solutions'' to clarify the intended use of this exception. Non-
infectious substances would not be subject to the HMR if they did not
otherwise meet the definition of any other hazard classes. This
clarification signals that the exception refers to specimens in
solutions that may contain preservatives that are hazardous materials,
such as formaldehyde and alcohol solutions.
Additionally, PHMSA is revising paragraph (a)(24) of this section,
which refers to small cartridges of carbon dioxide or other suitable
gas of Division 2.2. The exception states that small cartridges fitted
into devices with no more than four small cartridges are permitted.
This is inconsistent with the ICAO TI, which permits cartridges for
other devices indicating that spares are permitted. As Sec.
175.10(a)(24) currently reads, there is no mention of spare cartridges.
The HMR currently permits up to four small cartridges, and therefore,
PHMSA is revising this paragraph to state that small cartridges fitted
into or securely packed with devices with no more than four small
cylinders of carbon dioxide or other suitable gas in Division 2.2 are
permitted for carriage by passengers or crewmembers. This change
harmonizes the exception with international standards to clarify that
spares are permitted in addition to the cartridges already fitted into
the device, provided they are securely packed with the devices for
intended use.
Section 175.75
Section 175.75 describes the quantity limitations and cargo
locations for carriage by aircraft. Paragraph (e)(2) excepts packages
of hazardous materials transported aboard a cargo aircraft, when other
means of transportation are impracticable or not available, in
accordance with procedures approved
[[Page 35505]]
in writing by the FAA Regional or Field Security Office in the region
where the operator is located, from the requirements of paragraphs (c)
and (d) of Sec. 175.75. PHMSA is revising this paragraph by removing
the word ``located'' and replacing it with ``certificated.'' The words
``or Field Security'' are also removed. This amendment ensures that
operators interact with the Hazardous Materials Division Manager (HMDM)
who has already reviewed and recommended for approval the certificate's
hazmat-related manual(s) required under FAR Sec. 121.135. The HMDM (or
designee) will already have an understanding of the certificate's
operations and, as needed, will interact with the local resources and/
or the operator's certificate management team to assess the
impracticability or lack of availability of other cargo operations--as
well as what alternative procedures should be prescribed.
Part 176
Section 176.30
Section 176.30 prescribes the information required on dangerous
cargo manifests for vessel transport. Paragraph (a)(4) requires ``the
number and description of packages (e.g., barrels, drums, cylinders,
boxes, etc.) and gross weight for each type of packaging.'' In this
final rule, PHMSA is replacing the word ``packaging'' with ``package,''
as the term ``packaging'' refers to the means of containment and not
the completed package.
Part 177
Section 177.834
Section 177.834 establishes general operational requirements for
hazardous materials transportation by highway. Section 177.934(i)
prescribes attendance requirements for loading and unloading
operations. In a final rule published on January 21, 2016 [Docket No.
PHMSA-2013-0042 (HM-233F); 81 FR 3635], PHMSA codified DOT Special
Permits 9874, 13190, 13424, 13959, 14141, 14150, 14680, 14822, 14827,
and 14840 into Sec. 177.834(i) that 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 same final rule, PHMSA codified DOT Special
Permits 13484 and 14447 also into Sec. 177.834(i) that 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 final rule,
however, PHMSA inadvertently omitted the word ``or'' between each of
the four acceptable methods of determining compliance with the
attendance requirements adopted by the codification of the 12 special
permits. Thus, in this final rule, PHMSA is inserting the word ``or''
between each acceptable method in Sec. 177.834(i) as proposed in the
January 30, 2015 NPRM.
Section 177.848
Section 177.848 addresses segregation requirements for hazardous
materials transported by motor carrier. PHMSA received a request for a
letter of interpretation (Ref. No. 09-0268) requesting clarification
whether ``Boosters, 1.1D, UN0042, PG II'' and ``Ammonium nitrate, 5.1,
UN1942, PG III'' can be transported in the same vehicle. The requester
noted seemingly conflicting requirements in Sec. Sec. 177.835 and
177.848 applicable to the segregation of ammonium nitrate fertilizer
and explosive materials.
Section 177.848(e) provides instructions for using the segregation
table in Sec. 177.848(d). Presently, under Sec. 177.848(e)(5)
assignment of note ``A'' authorizes ammonium nitrate (UN1942) and
ammonium nitrate fertilizer to be loaded or stored with Division 1.1 or
Division 1.5 (explosive) materials. However, Sec. 177.835(c) provides
that Division 1.1 or 1.2 (explosive) materials may not be loaded into
or carried on any vehicle or a combination of vehicles under certain
conditions outlined in paragraphs (c)(1) through (4). PHMSA clarified
in the response letter that a Division 1.1 or 1.2 explosive may not be
loaded into or carried on any vehicle or a combination of vehicles that
does not conform to Sec. Sec. 177.835(c)(1) through (4), regardless of
the note ``A'' exception for UN1942 in Sec. 177.848(e)(5). In this
rulemaking, we are clarifying that the loading restrictions in Sec.
177.835(c)(1) through (4) are applicable to Sec. 177.848(e).
Part 178
Section 178.65
Section 178.65 applies to the manufacture of DOT Specification 39
non-reusable (non-refillable) cylinders. Paragraph (i) of this section
describes the required markings for DOT 39 cylinders. The reference to
Sec. 178.35(h) in Sec. 178.65(i)(1) is incorrect, as Sec. 178.35(h)
was removed under a final rule published July 20, 2011 [Docket No.
PHMSA-2009-0151 (HM-218F); 76 FR 43509], which consolidated the
inspector's report requirements found in Sec. 178.35(g) into paragraph
(c)(4) of that section, moved the manufacturer's report retention
requirements into paragraph (g) and removed paragraph (h). In this
final rule, PHMSA is revising Sec. 178.65(i)(1) to correctly reference
the manufacturer's report requirements in Sec. 178.35(g).
Section 178.337-17
Section 178.337-17 prescribes the marking requirements applicable
to MC 331 cargo tank motor vehicles. Paragraph (a) of this section
outlines general requirements for marking of MC 331 cargo tank motor
vehicles. PHMSA received a request for a letter of interpretation (Ref.
No. 04-0206) to clarify the applicability of these markings in Sec.
178.337-17(a). The request pointed out an incorrect use of the term
cargo tank as it applies to the requirement for specification plates
found in paragraph (a), which states that each cargo tank certified
after October 1, 2004 must have a corrosion-resistant metal name plate
(ASME Plate) and specification plate permanently attached to the cargo
tank by brazing, welding or other suitable means on the left side near
the front, in a place accessible for inspection.
In response, we stated that an MC 331 cargo tank must have a metal
name plate (also referred to as an ASME plate) permanently attached to
the cargo tank. In addition, an MC 331 cargo tank motor vehicle
certified after October 1, 2004, must have a specification plate that
includes the information specified in Sec. 178.337-17(c). In this
final rule, PHMSA is revising Sec. 178.337-17(a) to eliminate
confusion of the name plate and specification plate requirements.
Section 178.345-3
Section 178.345-3 prescribes general requirements for the
structural integrity of specification cargo tanks. Paragraph (c)(1) of
this section addresses stress in the cargo tank shell resulting from
normal operating loadings. PHMSA published a final rule on October 2,
2013 [Docket No. PHMSA-2013-0158 (HM-244F); 78 FR 60745; effective
October 1, 2013] intending to correct the formula presented in
paragraph (c)(1) for the figure ``SS2'' to read ``SS\2\.''
This correction correctly adjusted the
[[Page 35506]]
standard ``2'' in the term to be a superscript ``\2\'' but
inadvertently adjusted the second ``S'' from a subscript
``S'' to a standard ``S.'' This is incorrect, and in this
final rule, PHMSA is revising this portion of the formula in Sec.
178.345-3(c)(1) to read ``SS\2\''.
Section 178.955
Section 178.955 prescribes the design and testing criteria for
Large Packagings. Presently, if a manufacturer of a Large Packaging
wishes to construct a Large Packaging that differs from a listed
specification, there is no Associate Administrator approval provision
outlined in the HMR. However, the HMR alludes to the need for an
approval in the Large Packaging marking requirements in Sec.
178.910(a)(1)(ii). The HMR have approval provisions in Part 178 for
manufacturers of both non-bulk packagings and IBCs when constructing
packagings that differ from listed specifications. In this rulemaking,
we are proposing to include provisions consistent with the non-bulk
packaging and IBC approval provisions for Large Packagings in Sec.
178.955. Such Large Packagings must be shown to be equally as
effective, and the testing methods used must be equivalent. This change
resolves the issue with Sec. 178.910(a)(1)(ii) and is consistent with
both the UN Model Regulations and the IMDG Code, which prescribe
approval provisions for non-bulk packagings, IBCs, and Large
Packagings.
Part 179
Section 179.13
Section 179.13 includes limitations on rail tank car capacity and
gross weight. With certain exceptions, this section generally limits
the gross weight on rail of tank cars to 263,000 pounds. However, this
section has been revised numerous times over the last several years. On
January 13, 2009 [74 FR 1770], PHMSA added paragraph (b) to this
section authorizing tank cars designed to transport poisonous-by-
inhalation (PIH) materials and built with certain mandated safety
improvements (tank cars meeting the specifications of Sec.
173.244(a)(2) or (3) or Sec. 173.314(c) or (d)) to have a gross weight
on rail of up to 286,000 pounds provided any weight increase was not
used to increase product capacity. Subsequently, in an effort to
incorporate several widely used special permits providing relief from
the gross weight limitations of Sec. 179.13, PHMSA revised the section
on May 14, 2010 [75 FR 27205], to provide FRA with the authority to
approve the operation of tank cars containing materials other than PIH
materials at gross weights of up to 286,000 pounds. FRA published
notice of its approvals under this section on January 25, 2011 [76 FR
4250].
In 2011 [76 FR 51324; 51331], noting that the agency's stated
intent in the 2010 rule was to incorporate into the HMR existing
special permits related to tank car gross weight for tank cars carrying
both non-PIH materials and PIH materials by giving FRA authority to
approve tank car weights up to 286,000 pounds for both types of tank
cars, PHMSA proposed to revise Sec. 179.13 to correct the omission of
PIH material tank cars from FRA's approval authority. However, when
adopted as a final rule on June 25, 2012 [(HM-216B); 77 FR 37962;
37985], the regulatory language did not correct this inadvertent
omission. Instead, in the final HM-216B rule, Sec. 179.13 was revised
to provide that tank cars designed to transport PIH materials and built
with the required safety improvements set forth in Sec. 173.244(a)(2)
or (3) or Sec. 173.314(c) or (d)) ``may have a gross weight on rail of
up to 286,000 pounds upon approval by the Associate Administrator for
Railroad Safety, FRA.''
As clearly demonstrated by the 2009 and 2010 rules, it was not the
intent of either PHMSA or FRA to require FRA approval of tank cars
built to the enhanced standards of Sec. Sec. 173.244(a)(2) or (3) or
173.314(c) or (d) for those cars to operate at a gross rail load of
286,000 pounds. Accordingly, in this final rule PHMSA is revising Sec.
179.13 to correct this error by (1) making it clear that tank cars
containing PIH materials built to the enhanced standards of Sec.
173.244(a)(2) or (3) or Sec. 173.314(c) or (d) do not need FRA
approval to operate at gross rail loads of up to 286,000 pounds and (2)
providing for FRA approval of tank cars containing PIH materials that
do not meet the enhanced standards to operate at gross rail loads of up
to 286,000 pounds. PHMSA received one comment from The Chlorine
Institute in support of this revision.
Part 180
Section 180.209
Section 180.209 prescribes requalification requirements for DOT
specification cylinders. Paragraph (j) contains a reference to an
obsolete special provision. In a January 7, 2013 final rule [Docket No.
PHMSA-2009-0126 (HM-215K); 78 FR 1101], we removed and relocated
regulatory text from Sec. 172.102(c)(1) Special Provision 18 to Sec.
173.309(a), which prescribes the conditions when specification
cylinders may be described, offered, and transported in commerce as
fire extinguishers. In relocating the text, PHMSA did not update this
section to reflect the change. In this final rule, we are correcting
this inconsistency by replacing the reference to Sec. 172.102(c)(1)
Special Provision 18 with Sec. 173.309(a).
V. Regulatory Analyses and Notices
A. Statutory/Legal Authority for This Rulemaking
The Federal Hazardous Materials Transportation Law (49 U.S.C. 5101-
5128) authorizes the Secretary of Transportation (Secretary) to
``prescribe regulations for the safe transportation, including
security, of hazardous material in intrastate, interstate, and foreign
commerce.'' The Secretary delegated this authority to PHMSA in 49 CFR
1.97(b). If adopted as proposed, this final rule would make
miscellaneous amendments to the HMR, correct errors in the Sec.
172.101 HMT and corresponding special provisions, and respond to NTSB
Safety Recommendations related to the safe transportation of manifolded
acetylene cylinders.
Additionally, this final rule will respond to petitions for
rulemaking related to the allowable format for emergency telephone
numbers on shipping papers; relax the pressure test interval for
certain cargo tanks in dedicated propane service; enhance the safe
packaging for nitric acid; clarify the testing requirements for
specification cargo tank pressure relief devices; harmonize the hazard
communication requirements for poisonous-by-inhalation materials
transported by vessel; and eliminate a potentially confusing packing
group designation for certain organic peroxides, self-reactive
materials, and explosives. These amendments clarify regulatory
requirements and, where appropriate, decrease the regulatory burden
without compromising the safe transportation of hazardous materials in
commerce.
B. Executive Order 12866, Executive Order 13563, and DOT Regulatory
Policies and Procedures
This final rule is not considered a significant regulatory action
within the meaning of Executive Order 12866 (``Regulatory Planning and
Review'') and the Regulatory Policies and Procedures of the Department
of Transportation [44 FR 11034].
In this final rule, we amend miscellaneous provisions in the HMR
for clarification and relaxation of overly burdensome requirements,
with the intent of, thereby, increasing voluntary compliance while
reducing compliance
[[Page 35507]]
costs. As a result, PHMSA anticipates the amendments contained in this
rule will have economic benefits to the regulated community. Executive
Order 13563 (``Improving Regulation and Regulatory Review'') is
supplemental to and reaffirms the principles, structures, and
definitions governing regulatory review that were established in
Executive Order 12866 (``Regulatory Planning and Review'') of September
30, 1993. In addition, Executive Order 13563 specifically requires
agencies to: (1) Involve the public in the regulatory process; (2)
promote simplification and harmonization through interagency
coordination; (3) identify and consider regulatory approaches that
reduce burden and maintain flexibility; (4) ensure the objectivity of
any scientific or technological information used to support regulatory
action; and (5) consider how to best promote retrospective analysis to
modify, streamline, expand, or repeal existing rules that are outmoded,
ineffective, insufficient, or excessively burdensome.
In this final rule, PHMSA has involved the public in the regulatory
process in a variety of ways: Specifically, PHMSA is addressing issues
and errors that were identified for future rulemaking both through
letters of interpretation and other correspondence with PHMSA
stakeholders who brought editorial errors in the HMR to our attention.
In addition, PHMSA has responded to seven petitions for rulemaking and
two NTSB Safety Recommendations. PHMSA asked for public comments based
on the proposals in this NPRM, and upon receipt of public comment,
PHMSA has addressed all substantive comments in this rulemaking action.
The amendments in the final rule promote simplification and
harmonization through interagency coordination. In this final rule,
PHMSA is revising 49 CFR part 175, in a collaborative effort with the
Federal Aviation Administration (FAA), to: clarify the applicability of
the HMR to certain aircraft operators, clarify exceptions for
passengers and crewmembers, correct inaccurate references to title 14
of the CFR, and make minor editorial corrections applicable to air
operations to improve overall clarity. There are minimal additional
costs associated with these proposals; however, increased clarity will
result in net benefits.
This final rule also promotes harmonization with international
standards, such as the IMDG Code, Canada's TDG requirements, and the
ICAO TI. These efforts include:
Harmonizing hazard communication for poisonous-by-
inhalation materials with the IMDG Code and TDG regulations;
Removing the packing group II designation for certain
organic peroxides, self-reactive substances, and explosives to be
consistent with the UN Recommendations, IMDG Code, and ICAO TI, thus
facilitating international transport;
Harmonizing entries in the HMT with the above listed
international standards;
Revising the passenger exceptions applicable to small
cartridges containing Division 2.2 gas with the ICAO TI;
Harmonizing the excepted quantities requirements to mirror
language employed in the ICAO TI as they apply to articles.
These revisions to the Sec. 172.101 HMT will eliminate errors,
reduce ambiguity, harmonize the HMR with international regulations, and
improve clarity. Although these revisions are minor, they are expected
to produce a safety benefit derived from the increased clarity and
accuracy of the text in the Sec. 172.101 HMT.
This final rule permits flexibility in achieving compliance when
transporting damaged wet electric storage batteries; extends the
requalification interval for certain MC 331 cargo tanks in dedicated
propane service from five years to ten years for a pressure test and
internal visual inspection, therefore, fostering greater regulatory
flexibility without compromising transportation safety; clarifies the
regulations to provide flexibility in the ability to use the ``NOT-
ODORIZED'' or ``NON-ODORIZED'' marking on cargo tanks, cylinders, and
portable tanks containing odorized or unodorized LPG. Additionally, by
allowing 100 pounds of black or smokeless powder for small arms
reclassed as Division 4.1 in each transport vehicle, instead of each
motor vehicle, the regulated community can reduce the number of motor
vehicles needed to transport these goods.
Where PHMSA identified potential costs to stakeholders, specific
comment was requested to clarify such costs. We requested and responded
to specific comments on potential cost impacts of the proposals in
Sec. 172.604.
A majority of the amendments in this rulemaking are simple
clarifications and do not require significant scientific or
technological information. However, when necessary in this final rule,
PHMSA used scientific or technological information to support its
regulatory action. Specifically, such data was considered when
structuring alternatives on how to best deal with issues regarding the
testing of pressure relief devices for cargo tank motor vehicles, as
well as with issues regarding the extension of the pressure test and
internal visual inspection test interval from five to ten years for
certain MC 331 cargo tanks in dedicated propane delivery service. This
information was used in the evaluation of alternative proposals, and
ultimately this information determined how best to promote
retrospective analysis to modify and streamline existing requirements
that are outmoded, ineffective, insufficient, or excessively
burdensome.
C. Executive Order 13132
This final rule has been analyzed in accordance with the principles
and criteria contained in Executive Order 13132 (``Federalism''). This
final rule would preempt State, local, and Indian tribe requirements
but does not propose any regulation that has substantial direct effects
on the states, the relationship between the national government and the
states, or the distribution of power and responsibilities among the
various levels of government. Therefore, the consultation and funding
requirements of Executive Order 13132 do not apply.
The Federal Hazardous Material Transportation Law, 49 U.S.C.
5125(b)(1), contains an express preemption provision (49 U.S.C.
5125(b)) preempting State, local, and Indian tribe requirements on
certain covered subjects. Covered subjects are as follows:
(i) The designation, description, and classification of hazardous
materials;
(ii) The packing, repacking, handling, labeling, marking, and
placarding of hazardous materials;
(iii) The preparation, execution, and use of shipping documents
related to hazardous materials and requirements related to the number,
content, and placement of those documents;
(iv) The written notification, recording, and reporting of the
unintentional release in transportation of hazardous materials;
(v) The design, manufacture, fabrication, marking, maintenance,
reconditioning, repair, or testing of a packaging or container which is
represented, marked, certified, or sold as qualified for use in the
transport of hazardous materials.
This final rule concerns the classification, packaging, and
handling of hazardous materials, among other covered subjects. If
adopted, this rule would preempt any State, local, or Indian tribe
requirements concerning
[[Page 35508]]
these subjects unless the non-Federal requirements are ``substantively
the same'' (See 49 CFR 107.202(d) the Federal requirements.)
The Federal Hazardous Materials Transportation Law provides at 49
U.S.C. 5125(b)(2) that if PHMSA issues a regulation concerning any of
the covered subjects, PHMSA must determine and publish in the Federal
Register the effective date of Federal preemption. That effective date
may not be earlier than the 90th day following the date of issuance of
the final rule and not later than two years after the date of issuance.
The effective date of Federal preemption will be 90 days from
publication of a final rule on this matter in the Federal Register.
D. Executive Order 13175
This final rule has been analyzed in accordance with the principles
and criteria contained in Executive Order 13175 (``Consultation and
Coordination with Indian Tribal Governments''). Because this final rule
does not have tribal implications and does not impose substantial
direct compliance costs on Indian tribal governments, the funding and
consultation requirements of Executive Order 13175 do not apply and a
tribal summary impact statement is not required.
E. Regulatory Flexibility Act, Executive Order 13272, and DOT
Procedures and Policies
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an
agency to review regulations to assess their impact on small entities
unless the agency determines the rule is not expected to have a
significant impact on a substantial number of small entities. In
addition, the Regulatory Flexibility Act directs agencies to establish
exceptions and differing compliance standards for small businesses,
where it is possible to do so while still meeting the objectives of
applicable regulatory statutes. However, in the case of hazardous
materials transportation, it is not possible to establish exceptions or
differing standards and still accomplish our safety objectives.
As this final rule would clarify provisions based on PHMSA's
initiatives and correspondence with the regulated community, the impact
that it will have on small entities is not expected to be significant.
The changes are generally intended to provide relief and, as a result,
marginal positive economic benefits to shippers, carriers, and
packaging manufactures and testers, including small entities. These
benefits are not at a level that can be considered economically
significant. Consequently, this final rule will not have a significant
economic impact on a substantial number of small entities.
This final rule has been developed in accordance with Executive
Order 13272 (``Proper Consideration of Small Entities in Agency
Rulemaking'') and DOT's Procedures and Policies to promote compliance
with the Regulatory Flexibility Act to ensure that potential impacts of
draft rules on small entities are properly considered.
F. Paperwork Reduction Act
PHMSA currently has an approved information collection under Office
of Management and Budget (OMB) Control Number 2137-0557, entitled
``Approvals for Hazardous Materials.'' This final rule does not make
any changes that would affect the burden for this or any other
information collection.
Prior to the publication of a final rule entitled ``Hazardous
Materials: Revisions to Fireworks Regulation'' published in the Federal
Register on July 6, 2013 [Docket No. PHMSA-2010-0320 (HM-257); 78 FR
42457], the HMR contained a requirement that all certification agencies
provide a statement confirming that it would perform its functions
independent of the owners and manufacturers of the packagings in its
field. The burden for this requirement was accounted for under OMB
Control Number 2137-0557. However, the HM-257 final rule inadvertently
removed this language from the HMR. Therefore, in this final rule,
PHMSA is reinserting the language for certification agencies to confirm
that they are independent and not owned by a company in its field. For
ease of the reader, this language is to be inserted as follows:
PHMSA is revising Sec. 107.402(f) to require that a
portable tank and MEGC certification agency submit a statement
indicating that the agency is independent of and not owned by a
portable tank or MEGC manufacturer, owner, or distributor as part of
the Portable tank and MECG Certification Agency application.
PHMSA is revising Sec. 107.402(e) to require that a
lighter certification agency submit a statement that the agency is
independent of and not owned by a lighter manufacturer, distributor,
import or export company, or proprietorship as part of the Lighter
Certification Agency application.
PHMSA is revising Sec. 107.807 to require that a person
who seeks to manufacture DOT specification cylinders and special permit
cylinders, or perform chemical analysis and tests of those cylinders
outside the United States submits a statement, as part of the
application, indicating that the inspection agency is independent of
and not owned by a cylinder manufacturer, owner, or distributor.
G. Regulation Identifier Number (RIN)
A regulation identifier number (RIN) is assigned to each regulatory
action listed in the Unified Agenda of Federal Regulations. The
Regulatory Information Service Center publishes the Unified Agenda in
April and October of each year. The RIN number contained in the heading
of this document can be used to cross-reference this action with the
Unified Agenda.
H. Unfunded Mandates Reform Act
This final rule does not impose unfunded mandates under the
Unfunded Mandates Reform Act of 1995. It does not result in costs of
$141,300,000 or more to either State, local, or tribal governments, in
the aggregate, or to the private sector, and it is the least burdensome
alternative that achieves the objective of the rule.
I. Environmental Assessment
The National Environmental Policy Act of 1969 (NEPA), 42 U.S.C.
4321-4375, requires that Federal agencies analyze proposed actions to
determine whether the action will have a significant impact on the
human environment. In accordance with the Council on Environmental
Quality (CEQ) regulations (40 CFR parts 1500-1508), which implement
NEPA, an agency may prepare an Environmental Assessment (EA) when it
does not anticipate that the final action will have significant
environmental effects. They must consider the following: (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)).
1. Purpose and Need
The purpose of this final rule is to amend the Hazardous Materials
Regulations (HMR; 49 CFR parts 171-180) by making miscellaneous
revisions to update and clarify certain regulatory requirements, to
respond to seven petitions for rulemaking submitted to PHMSA by various
stakeholders, and to address two NTSB recommendations. These
amendments, which were identified through an internal review of the HMR
as well as in response to communications with various stakeholders, are
intended to promote safety, regulatory relief, and clarity. This action
is necessary in order to: (1) Fulfill
[[Page 35509]]
our statutory directive to promote transportation safety; (2) fulfill
our statutory directive under the Administrative Procedure Act (APA)
that requires Federal agencies to give interested persons the right to
petition an agency to issue, amend, or repeal a rule (5 U.S.C. 553(e));
(3) support governmental efforts to provide regulatory relief to the
regulated community; (4) address safety concerns raised by the NTSB and
remove regulatory ambiguity identified by the regulated community; and
(5) simplify and clarify the regulations in order to promote
understanding and compliance.
The intended effect of this action is to enhance the safe
transportation of hazardous materials and, in conjunction, clarify,
simplify, and relax certain regulatory requirements for carriers,
shippers, and other stakeholders. These regulatory revisions will offer
more efficient and effective ways of achieving safe and secure
transportation of hazardous materials in commerce.
2. Alternatives
The alternatives considered in this Environmental Assessment
include the following:
Alternative 1: No Action
Alternative 1 would not result in any rulemakings on this subject,
leaving the current regulatory standards to remain in effect. As a
result, this option would not address outstanding petitions for
rulemaking or NTSB Safety Recommendations. While this alternative would
not impose any new costs or change any environmental impacts, neither
would it account for the outstanding petitions for rulemaking, NTSB
Safety Recommendations, and regulatory concerns reviewed by PHMSA;
thus, we have rejected the no action alternative.
Alternative 2: Go Forward With the Proposed Amendments to the HMR in
This NPRM
Alternative 2 revises the HMR as proposed in the NPRM and,
accounting for public comment, applies to transportation of hazardous
materials by various modes (highway, rail, vessel and aircraft). The
amendments encompassed in this alternative are more fully addressed in
the preamble and regulatory text sections. However, they generally
include the following changes to the HMR, grouped below for ease of
discussion:
Incorporation by Reference and Use of International Standards:
Remove the entry for CGA Publication C-1.1 in Table 1 to
Sec. 171.7.
Incorporate by reference in Sec. 171.7 CGA Publication G-
1.6, Standard for Mobile Acetylene Trailer Systems, Seventh Edition
(responds to petition P-1605 and two NTSB Safety Recommendations, H-09-
01 and H-09-02).
Amend Sec. 171.7(k) to include Sec. Sec. 179.24 and
180.503.
Amend the marking requirements for poisonous-by-inhalation
shipments transported in accordance with the IMDG Code or TDG
Regulations (responds to petition for rulemaking P-1591).
Sec. 172.101 Hazardous Materials Table and Sec. 172.102 Special
Provisions:
Remove the Packing Group (PG) II designation for certain
organic peroxides, self-reactive substances and explosives (responds to
petition for rulemaking P-1590).
Revise the Sec. 172.101 table to add Special Provision
B120 to Column 7 for the entry ``Calcium nitrate, UN1454.''
Revise the entry for ``Propellant, solid, UN0501'' to
remove vessel stowage provision 24E from Column (10B) of the HMT.
Revise the PG II HMT entry for ``Corrosive liquids,
flammable, n.o.s., UN2920,'' to harmonize the HMR with the UN Model
Regulations, IMDG Code, and the ICAO TI by adding a reference to Sec.
173.154 to Column (8A) of the HMT.

1. Probable Environmental Impacts of the Alternatives
Hazardous materials are substances that may pose a threat to public
safety or the environment during transportation because of their
physical, chemical, or nuclear properties. Under the HMR, hazardous
materials are transported by aircraft, vessel, rail, and highway. The
potential for environmental damage or contamination exists when
packages of hazardous materials are involved in accidents or en route
incidents resulting from cargo shifts, valve failures, package
failures, loading, unloading, collisions, handling problems, or
deliberate sabotage. The release of hazardous materials can cause the
loss of ecological resources (e.g. wildlife habitats) and the
contamination of air, aquatic environments, and soil.
When developing potential regulatory requirements, PHMSA evaluates
those requirements to consider the environmental impact of each
amendment. Specifically, PHMSA evaluates the following: The risk of
release of hazmat and resulting environmental impact; the risk to human
safety, including any risk to first responders; the longevity of the
packaging; and the circumstances in which the regulations would be
carried out (i.e., the defined geographic area, the resources, any
sensitive areas) and how they could thus be impacted.
PHMSA has determined that most of the regulatory changes proposed
in this rulemaking are editorial in nature. As such, these amendments
have no impact on the risk of release and resulting environmental
impact, human safety, longevity of the packaging, and none of these
amendments would be carried out in a defined geographic area. General
possible environmental benefits, and detriments, are discussed below.
Alternative 1
The no-action alternative would result in no changes. The current
regulations would remain in place, and no new provisions would be
added. However, this option would not address outstanding petitions for
rulemaking, NTSB Safety Recommendations or consider amendments based on
PHMSA's own initiatives intended to update, clarify, or provide relief
from certain existing regulatory requirements. Foregone efficiencies in
the Alternative 1 also include freeing up limited resources to
concentrate on hazardous materials transportation issues of potentially
much greater environmental impact.
Not adopting the proposed environmental and safety requirements in
the final rule under the Alternative 1 would result in a lost
opportunity for reducing environmental and safety-related incidents.
In addition, greenhouse gas emissions would remain the same under
the Alternative 1.
Alternative 2
If PHMSA selects the provisions as amended in this final rule, we
believe that safety and environmental risks would be reduced and that
protections to human health and environmental resources would be
increased.
Alternative 2 will enhance environmental protection through more
targeted and effective training. This set of amendments will eliminate
inconsistent hazardous materials regulations, which hamper compliance
training efforts. By maintaining consistency between these
international regulations and the HMR, shippers and carriers are able
to train their hazardous materials employees in a single set of
requirements for classification, packaging, hazard communication,
handling, and stowage, thereby minimizing the possibility of improperly
preparing and transporting a shipment of hazardous materials because of
differences between domestic and international regulations.
In addition, Alternative 2 will create more streamlined hazardous
regulations, resulting in compliance training efforts which facilitate
the regulated community's ability to comply with the HMR. Potential
environmental impacts of each group of amendments in Alternative 2
(selected for this final rule) are discussed individually below:
Incorporation by Reference and Use of International Standards:
PHMSA believes that this set of amendments, which will increase
standardization and consistency of regulations, will result in greater
protection of human health and the environment. Consistency between
U.S. and international regulations enhances the safety and
environmental protection of international hazardous materials
transportation through better understanding of the regulations, an
increased level of industry compliance, the smooth flow of hazardous
materials from origin to destination, and consistent emergency response
in the event of a hazardous materials incident. Incorporation of the
CGA Publication G-1.6, Standard for Mobile Acetylene Trailer Systems,
will mitigate acetylene release and enhance environmental protection
during overturn incidents and unloading.
[[Page 35511]]
Current greenhouse gas emissions would be unaffected under this
proposed set of amendments.
Sec. 172.101 Hazardous Materials Table and Sec. 172.102 Special
Provisions:
PHMSA believes that this set of amendments, which will increase
standardization and consistency of regulations, will result in greater
protection of human health and the environment. As previously stated,
consistency between U.S. and international regulations enhances the
safety and environmental protection of international hazardous
materials transportation through better understanding of the
regulations, an increased level of industry compliance, the smooth flow
of hazardous materials from their points of origin to their points of
destination, and consistent emergency response in the event of a
hazardous materials incident. New and revised entries to the HMT
reflect emerging technologies and the need to better describe or
differentiate between existing entries. These changes mirror those in
the Dangerous Goods list of The 18th Revised Edition of the UN Model
Regulations, the 2013-2014 ICAO TI and the 37-14 amendments to the IMDG
Code. It is extremely important for the domestic HMR to mirror the UN
Model Regulations, the ICAO TI, and the IMDG Code with respect to the
entries in the HMT to ensure consistent naming conventions across modes
and international borders.
The packing group assignment reflects a degree of danger associated
with a particular material and identifies appropriate packaging.
However, assignment of a packing group is not appropriate in all cases
(e.g. explosives, gases, radioactive material). In such cases the
packing group does not indicate a degree of danger, and the packaging
requirements for those materials are specified in the appropriate
section in part 173. The change to eliminate a packing group
designation for materials classified as explosives and organic
peroxides specifically listed in the HMT provides a level of
consistency, without diminishing environmental protection and safety.
Current greenhouse gas emissions would be unaffected under this set
of amendments.
Hazard Communication (Marking, Labeling, Placarding, Emergency
Response):
PHMSA believes that this set of amendments, which will provide for
enhanced hazard communication (hazcom), will result in greater
protection of human health and the environment. The proposed changes
communicate the nature of various specialized packaging configurations
to package handlers and emergency responders. The amendments would
ensure that hazard markings are visible, universally recognizable, and
that they contain all information needed by emergency responders, thus
resulting in fewer incidents with impacts to the environment and
safety.
Similar to the above sets of amendments, PHMSA believes consistency
between U.S. and international regulations enhances the safety and
environmental protection of international hazardous materials
transportation through better understanding of the regulations, an
increased level of industry compliance, the smooth flow of hazardous
materials from their points of origin to their points of destination,
and consistent emergency response in the event of a hazardous materials
incident.
Current greenhouse gas emissions would be unaffected under this
proposed set of amendments.
Shipper Requirements:
PHMSA believes that this amendment, which will revise, clarify and
enhance current regulations, will result in greater protection of human
health and the environment. Shippers and transporters of hazardous
materials will more easily be able to comply with the HMR through
regulations that are easier to understand and more streamlined.
Specific to this set of amendments, improving the packaging
requirements applicable to glass packages of nitric acid reduces the
occurrences of fires caused by broken inner containers and enhances
human health and environmental protection. PHMSA believes that the
additional intermediate packaging required by this particular amendment
will add another layer of protection in preventing breakage, leakage,
and fires. Additionally, this particular amendment creates a more
streamlined and efficient HMR through incorporation of a petition for
rulemaking (P-1601), whic allows both regulators and the regulated
community to target limited resources at the most pressing hazmat
compliance issues.
Current greenhouse gas emissions would be unaffected under this
proposed set of amendments.
Modal Requirements (Air, Vessel, and Highway):
PHMSA believes that this amendment, which will revise, clarify, and
enhance current regulations, will result in greater protection of human
health and the environment. Air, vessel, and highway shippers and
transporters of hazardous materials will more easily be able to comply
with the HMR through regulations that are easier to understand and more
streamlined. Additionally, the revisions include emphasis being placed
in areas requiring more attention.
Current greenhouse gas emissions would be unaffected under this
proposed set of amendments.
Packaging Design and Requalification:
PHMSA believes that this amendment, which will revise, clarify, and
enhance current regulations, will result in greater protection of human
health and the environment. Shippers and transporters of hazardous
materials will more easily be able to comply with the HMR through
regulations which are easier to understand and more streamlined.
Additionally, the revisions include emphasis being placed in areas
requiring more attention.
Specific to this set of amendments, decreasing the required
frequency for pressure testing and visual inspection of certain cargo
tanks in dedicated propane service by extending the requalification
period from five years to ten years will ease the burden on regulators
and the regulated community. This test, which requires significant
equipment down-time and man-hours to perform, has been shown to achieve
no additional safety or environmental protection when performed at a
five- versus a ten-year interval. In addition, pressure testing
requires a significant amount of water usage. Decreasing the testing
frequency by half will result in significant volumes of water being
conserved. Additionally, this particular amendment creates a more
streamlined and efficient HMR through incorporation of a petition for
rulemaking (P-1609). A more streamlined and efficient HMR allows both
regulators and the regulated community to target limited resources at
the most pressing hazmat compliance issues.
Current greenhouse gas emissions would be unaffected under these
amendments.
1. Agencies Consulted
This final rule would affect some PHMSA stakeholders, including
hazardous materials shippers and carriers by highway, rail, vessel, and
aircraft, as well as package manufacturers and testers. PHMSA sought
comment on the environmental assessment contained in the NPRM. In
addition, PHMSA specifically coordinated with the following Federal
agencies and modal partners:
Department of Justice
[[Page 35512]]
Environmental Protection Agency
Health and Human Services
Occupational Safety and Health Administration
Federal Aviation Administration
Federal Motor Carrier Safety Administration
Federal Railroad Administration
United States Coast Guard
2. Conclusion
PHMSA is adopting miscellaneous amendments to the HMR based on
comments from the regulated community, NTSB recommendations, and
PHMSA's own rulemaking initiatives. The amendments are intended to
update, clarify, or provide relief from certain existing regulatory
requirements to promote safer transportation practices; eliminate
unnecessary regulatory requirements; facilitate international commerce;
and make these requirements easier to understand. These clarifications
of regulatory requirements will foster a greater level of compliance
with the HMR and, thus, diminish levels of hazardous materials
transportation incidents affecting the health and safety of the
environment. Therefore, the net environmental impact of this proposal
will be positive.
J. Privacy Act
In accordance with 5 U.S.C. 553(c), DOT solicits comments from the
public to better inform its rulemaking process. The DOT posts these
comments, without edit, including any personal information the
commenter provides, to www.regulations.gov. The electronic form of
these written communications and comments can be searched by the name
of the individual submitting the document (or signing the document, if
submitted on behalf of an association, business, labor union, etc.).
The DOT's complete Privacy Act Statement is available at http://www.dot.gov/privacy.
K. International Trade Analysis
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. Pursuant to these Acts, establishing standards is
not considered an unnecessary obstacle to the foreign commerce of the
United States, so long as the standards have a legitimate domestic
objective, such as the protection of safety, and do not operate in a
manner that excludes imports that meet this objective. This statute
also requires consideration of international standards and, where
appropriate, that they be the basis for U.S. standards. PHMSA notes the
purpose is to ensure the safety of the American public and has assessed
the effects of this rule to ensure that it does not exclude imports
that meet this objective. As a result, this final rule is not
considered as creating an unnecessary obstacle to foreign commerce.
