I. Executive Summary

    PHMSA is adopting several amendments proposed in the HM-265 notice 
of proposed rulemaking (NPRM) titled Hazardous Materials: Advancing 
Safety of Highway, Rail, and Vessel Transportation.\1\ These amendments 
will reduce costs and eliminate unnecessary regulatory burdens on the 
transportation of hazardous materials, including energy products, while 
maintaining the current level of safety provided by the Hazardous 
Materials Regulations (HMR; 49 CFR parts 171-180). The amendments 
adopted in this final rule are:
---------------------------------------------------------------------------

    \1\ 89 FR 85590 (Oct. 28, 2024).
---------------------------------------------------------------------------

     In part 107, subpart F, revise the cargo tank facility 
registration requirements to allow for electronic submission 
procedures.
     In section 171.7, replace the current incorporation by 
reference of Chlorine Institute (CI) drawings in paragraphs (l)(3) and 
(l)(4) with the entire CI Pamphlet 49, Recommended Practices for 
Handling Chlorine Bulk Highway Transports, which provides guidelines 
for the safe transportation of chlorine by highway. The updated 
incorporation by reference includes the use of the Midland Type 
pressure relief device (PRD) for cargo tanks transporting chlorine as 
referenced in updated section 173.315.
     In section 172.336, revise the marking requirements for 
multiple petroleum distillate fuels to allow the marking of the 
identification number of the fuel with the lowest flash point 
transported in the same or previous business day.
     In section 172.704, include hazmat employees who only 
manufacture packagings within the scope of the existing exception from 
safety training. Further, remove the security awareness training 
requirement for any hazmat employees who only perform hazmat activities 
related to packagings (e.g., employees who manufacture, repair, modify, 
recondition, or test packagings,

[[Page 1434]]

and do not offer for transportation or transport hazardous materials in 
commerce).
     In section 178.337-1(d), allow the use of external 
coverings other than paint that meet reflectivity requirements for 
Cargo Tank Motor Vehicles (CTMVs).
     In section 180.407(a)(7), allow the use of video cameras 
or video optics equipment for cargo tank inspections or tests.
    PHMSA included several other proposals in the NPRM that are not 
being advanced in this final rule. The proposals included, among other 
things, amendments to the HMR to address 2017 Rail Safety Advisory 
Committee (RSAC) consensus recommendations; the Association of American 
Railroads' (AAR) delegated authority to approve tank car designs and 
tank car facility quality assurance programs; revisions to the 
construction and qualification of highway CTMVs; revisions to improve 
the safe transport of hazardous materials by vessel; and other multi-
modal provisions. PHMSA is continuing to evaluate the merits of these 
proposals and may publish another final rule at a later date.\2\
---------------------------------------------------------------------------

    \2\ In response to the NPRM, PHMSA received 37 sets of 
comments--of which only nine are relevant to the issues included in 
this final rule. Only those nine comments relevant to the topics 
addressed in this final rule will be discussed in this final rule.
---------------------------------------------------------------------------

    The amendments adopted in this final rule provide substantial cost 
savings by reducing unnecessary burdens on the transportation of 
petroleum distillate fuels, such as gasoline and diesel fuel, by motor 
carriers. This final rule also provides cost savings to the hazardous 
materials packaging industry by removing an unnecessary training 
requirement and adopting measures allowing the use of technologies that 
introduce efficiencies for cargo tank tests and inspections. Together, 
the amendments adopted in this final rule provide a quantified cost 
savings of approximately $145.3 million per year, while also providing 
qualitative benefits to energy transportation through greater 
regulatory flexibility for cargo tank owners and cargo tank facility 
operators.

II. Incorporation by Reference Discussion Under 1 CFR Part 51

    PHMSA currently incorporates by reference into the HMR all or parts 
of numerous standards and specifications developed and published by 
standards development organizations (SDO). In general, SDOs accredited 
as voluntary consensus standards bodies develop, establish, or 
coordinate technical standards using agreed-upon procedures and update 
and revise their published standards every two to five years to reflect 
modern technology and best technical practices. The National Technology 
Transfer and Advancement Act of 1995 (NTTAA; Pub. L. 104-113) directs 
Federal agencies to use standards developed by voluntary consensus 
standards bodies in lieu of government-written standards whenever 
possible. The Office of Management and Budget (OMB) issued Circular A-
119, Federal Participation in the Development and Use of Voluntary 
Consensus Standards and in Conformity Assessment Activities,\3\ to 
implement section 12(d) of the NTTAA relative to the utilization of 
consensus technical standards by Federal agencies. This circular 
provides guidance for agencies participating in voluntary consensus 
standards bodies and describes procedures for satisfying the reporting 
requirements in the NTTAA.
---------------------------------------------------------------------------

    \3\ 81 FR 4673 (Jan. 27, 2016).
---------------------------------------------------------------------------

    PHMSA is responsible for determining which standards currently 
referenced in the HMR should be updated, revised, or removed, and which 
standards should be added to the HMR, under the NTTAA and OMB Circular 
A-119. Revisions to materials incorporated by reference in the HMR are 
handled via the rulemaking process, which allows for the public and 
regulated entities to provide input. During the rulemaking process, 
PHMSA must also obtain approval from the Office of the Federal Register 
to incorporate by reference any new materials. The Office of the 
Federal Register issued a rulemaking \4\ that revised 1 CFR 51.5 to 
require that an agency detail in the preamble of a rulemaking the ways 
the materials it proposes to incorporate by reference are reasonably 
available to interested parties, or how the agency worked to make those 
materials reasonably available to interested parties. Changes to the 
material incorporated by reference in the HMR are detailed in the 
section 171.7 discussion in ``Section V. Section-by-Section Review of 
Amendments.''
---------------------------------------------------------------------------

    \4\ See ``Incorporation by Reference,'' 79 FR 66267, 66278 (Nov. 
7, 2014).
---------------------------------------------------------------------------

    In this final rule, PHMSA incorporates by reference the CI Pamphlet 
49 in its entirety, rather than incorporating individual valve design 
drawings from the document as was done in the past. This authorizes an 
additional pressure relief valve design for cargo tanks in chlorine 
service. PHMSA has reviewed Pamphlet 49, including the valve design 
drawing mentioned, and found this new valve meets PHMSA's safety 
standards, and that incorporating this document by reference into the 
HMR will not reduce safety but instead will allow more flexibility for 
CTMV owners and operators.
    The Chlorine institute sells their standards one their website. The 
edition of the Pamphlet 49 incorporated by reference in this final rule 
can be obtained by contacting the Chlorine Institute bookstore by phone 
at (703) 894-4140, by email at [email protected], or at their contact page 
at https://www.chlorineinstitute.org/contact-us.

III. Identification Number Markings for Petroleum Distillate Fuels

A. Background

    The HMR require bulk packages containing hazardous materials to be 
marked with the identification number assigned to the hazardous 
material contained in the package--see section 172.302. This 
requirement is often met by displaying the required identification 
number inside the hazard class placard that is also displayed on the 
bulk package--see section 172.332(c) and (d). The requirement to mark 
the identification number on a cargo tank may also be met by using an 
orange panel or white square-on-point--see sections 172.328, 
172.332(b), and 172.336(b), respectively.
    The Hazardous Materials Table (HMT) in section 172.101 contains 
hundreds of identification numbers for flammable liquids. Flammable 
liquids, also known as Class 3 materials, are defined as liquids that 
have a flash point less than or equal to 60 [deg]C (140 [deg]F)--see 
section 173.120(a). Flash point means the minimum temperature at which 
a liquid gives off vapor within a test vessel in sufficient 
concentration to form an ignitable mixture with air near the surface of 
the liquid--see section 173.120(c). Generally, liquids with a lower 
flash point present a greater relative hazard than those with higher 
flash points because they can ignite at lower temperatures.
    Many of the fuels Americans rely on to power their cars, trucks, 
and boats, and to heat their homes are flammable liquids derived from 
the distillation of crude oil.\5\ These fuels, which include gasoline 
(UN1203), kerosene (UN1223), diesel fuel (NA1993/UN1202), and fuel oil 
(NA1993), are commonly referred to

[[Page 1435]]

as ``petroleum distillate fuels.'' Gasoline has a flash point of -45 
[deg]C (-49 [deg]F) \6\ compared to 52 [deg]C (126 [deg]F) for diesel 
fuel,\7\ 37.8 [deg]C (100 [deg]F) for kerosene, and 38 [deg]C (100.4 
[deg]F) \8\ to 58 [deg]C (136 [deg]F) \9\ for fuel oil. It is not 
uncommon for a CTMV in fuel delivery service to deliver multiple types 
of fuel requiring different identification numbers in a single day's 
operation--for instance, delivering gasoline on one trip, and diesel 
fuel on the next.
---------------------------------------------------------------------------

    \5\ The distillation process separates crude oil into its 
component hydrocarbons. During distillation, crude oil is heated, 
with different refined products recovered as the boil temperature is 
gradually increased. See U.S. Energy Information Administration, 
Crude Oil Distillation and the Definition of Refinery Capacity (July 
5, 2012), available at: https://www.eia.gov/todayinenergy/detail.php?id=6970#.

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

    PHMSA's Emergency Response Guidebook (ERG) provides the same 
initial emergency response instructions for all petroleum distillate 
fuels-see Guide 128.\10\ Because the initial emergency response 
instructions are the same, PHMSA proposed allowing cargo tanks to 
display the identification number of the petroleum distillate fuel with 
the lowest flash point transported in the cargo tank in the HM-265 
NPRM. As discussed in more detail below, this proposal is aligned with 
regulatory history and the original intent of the provisions when they 
were first added to the HMR.

1. HM-118
    In the HM-118 final rule \11\ titled Identification Numbers, 
Hazardous Wastes, Hazardous Substances, International Descriptions, 
Improved Descriptions, Forbidden Materials, and Organic Peroxides, the 
Research and Special Programs Administration (RSPA)--PHMSA's 
predecessor agency--amended the requirements in section 172.336 to 
allow the identification number of the lowest flash point fuel 
transported in a cargo tank to be displayed during shipment. RSPA 
adopted this amendment in section 172.336(c)(5) ``to eliminate the need 
for continuous changes in identification numbers in many operations 
where gasoline and fuel oil are transported in the same cargo tank on 
different trips during the same day.'' \12\ This amendment remained in 
place for more than 30 years until PHMSA inadvertently eliminated the 
provision in a subsequent final rule.

2. HM-219
    In 2013, PHMSA published another final rule titled Hazardous 
Materials: Miscellaneous Petitions for Rulemaking (RRR) (HM-219).\13\ 
In HM-219, PHMSA replaced sections 172.336(c)(1)-(6) with a table to 
``more clearly indicate hazard communication requirements.'' \14\ In 
the new table, PHMSA added paragraphs (c)(1)-(3) and (c)(6) as 
individual entries but consolidated the language in paragraphs (c)(4) 
and (5) into a single entry. PHMSA did not intend to change the 
original intent of paragraphs (c)(4) and (5) in consolidating these 
provisions, but the language used in the new table had that effect.

3. 2016 PIPES Act
    In 2016, Congress passed a statute addressing the identification 
number marking requirements for petroleum distillate fuels. 
Specifically, in the Protecting our Infrastructure of Pipelines and 
Enhancing Safety Act of 2016 (2016 PIPES Act),\15\ Congress included a 
mandate stating that, ``[n]ot later than 90 days after the date of 
enactment of this Act, the Secretary of Transportation shall issue an 
[ANPRM] to take public comment on the petition for rulemaking dated 
October 28, 2015, titled `Corrections to Title 49 CFR 172.336 
Identification numbers; special provisions' (P-1667).'' The rulemaking 
petition referenced in the mandate (P-1667 \16\)--and an additional 
petition (P-1668 \17\)--had been filed after PHMSA inadvertently 
altered the identification number marking requirements for petroleum 
distillate fuels in HM-219.

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

4. HM-213E
    Shortly after the passage of the 2016 PIPES Act, PHMSA published 
the advance notice of proposed rulemaking (ANPRM) titled Hazardous 
Materials: PIPES Act Requirements for Identification Numbers on Cargo 
Tanks Containing Petroleum Based Fuel (HM -213E).\18\ The central issue 
addressed in the HM-213E ANPRM was whether a CTMV transporting 
different types of petroleum distillate fuels (e.g., gasoline, diesel 
fuel, kerosene, and fuel oil) over the course of multiple trips should 
be permitted to display the identification number of the fuel with the 
lowest flash point previously transported, even when that fuel is not 
currently contained in the cargo tank (e.g., display ``1203''--the 
identification number for gasoline--when the cargo tank contains only 
diesel fuel on that trip).\19\
---------------------------------------------------------------------------

    \18\ 81 FR 83190 (Nov. 21, 2016).
    \19\ The HM-265 NPRM includes a discussion of comments received 
in response to the HM-213E ANPRM because certain portions of the HM-
213E rulemaking were incorporated into this HM-265 rulemaking.
---------------------------------------------------------------------------

    PHMSA received 14 sets of comments to the HM-213E ANPRM, split 
between those supporting the provisions allowing the display of the 
identification number of the fuel with the lowest flash point 
previously transported, and those opposed. PHMSA received no specific 
information describing actual instances in which the marking exception 
led to increased risks in transportation.\20\
---------------------------------------------------------------------------

    \20\ Please see the HM-265 NPRM's discussion of the HM-213E 
ANPRM comments for details on the commenters, comments, and PHMSA's 
responses. 89 FR at 85599.
---------------------------------------------------------------------------

5. DOT-SP 21104
    After publishing the HM-213E ANPRM, PHMSA issued Department of 
Transportation (DOT) Special Permit (SP) 21104 \21\ on November 11, 
2020. DOT-SP 21104, as further modified on February 26, 2021, allows 
for the transportation of gasoline, diesel fuel, kerosene, and fuel oil 
in a CTMV marked with the identification number ``1203'' provided 
gasoline, which has the lowest flash point of the fuels listed, had 
been transported in the cargo tank during the previous or current 
business day. DOT-SP 21104 has been in place for almost five years, and 
PHMSA is not aware of any safety issues associated with its use.
---------------------------------------------------------------------------

    \21\ See DOT-SP 21104, available at: https://www.phmsa.dot.gov/hazmat/documents/offer/SP21104.pdf/2021014464/SP21104.
---------------------------------------------------------------------------

6. HM-265
    Consistent with the rulemaking history and requirements in DOT-SP 
21104, PHMSA proposed to reinstate the original exception to the 
identification number marking requirements for petroleum distillate 
fuels in HM-265. PHMSA estimated that this amendment would generate 
cost savings of $145.3 million per year in 2024 dollars, primarily in 
time savings for petroleum distillate fuel carriers who would no longer 
be required to change the identification number displayed on their 
vehicle as frequently. Note that gasoline and ethanol blends that 
contain more than 10 percent ethanol have different physical properties 
and may require the

[[Page 1436]]

application of different types of fire suppression foam. Therefore, 
these fuels, including ``UN3475, Ethanol and gasoline mixture or 
Ethanol and motor spirit mixture or Ethanol and petrol mixture, with 
more than 10% ethanol, 3, PGII'' and ``UN1987, Alcohols, n.o.s., 3, PG 
I, II or III'' are not included in this marking provision. The ID 
numbers ``UN3475'' and ``UN1987'' must be displayed if those products 
are contained in the packaging and may not be displayed if the products 
are not contained in the packaging.

B. Action Taken in This Final Rule

    PHMSA is adopting the amendments as proposed.

C. Response to NPRM Comments

    PHMSA received nine sets of comments addressing the proposal to 
authorize cargo tanks and tank cars to display the identification 
number of the petroleum distillate fuel with the lowest flash point 
transported on that day or the previous business day. The following 
table identifies each of these commenters and the unique docket 
identifier for their comment.

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

    PHMSA received supportive comments from United States 
Representative Pete Stauber, EMA, Dow Chemical Company, and DGAC. PHMSA 
received opposing comments from the IAFF, IAFC, CVSA, PVA, and KHP. 
Both sets of comments are summarized and addressed below.
1. Supportive Stakeholder Comments for This Provision
    PHMSA received supportive comments from Representative Pete 
Stauber, EMA, Dow Chemical Company, and DGAC. Dow Chemical Company and 
DGAC expressed general support for proposed markings for petroleum 
distillate fuels changes, while Rep. Pete Stauber and EMA provided more 
detailed comments.
    Specifically, Rep. Pete Stauber accurately noted that the proposed 
amendment restores a previously authorized exception in the HMR. 
Shippers that transported diesel fuel, heating oil, and gasoline in 
separate loads were allowed to affix permanent placards with the 
``UN1203'' marking to their CTMVs rather than changing the placard with 
each subsequent load of a different material. Rep. Pete Stauber also 
presented information from his constituents indicating that the cost of 
complying with the current marking requirements is up to $800 per 
truck.\22\ Rep. Pete Stauber presented information from local fire 
chiefs as well, most of whom provided feedback agreeing that in their 
firefighting operations they respond the same way with the same type of 
foam, regardless of whether the placard is marked as 1203 or 1993.
---------------------------------------------------------------------------

    \22\ This estimate did not include potential penalties or red 
tagging from marking errors, when compared to the previously 
permissible marking requirements.
---------------------------------------------------------------------------

    EMA supported the proposed change to section 172.336(c), stating 
that removing the requirement to change identification numbers with 
each load when hauling multiple fuels of differing flashpoints in 
alternating trips provides meaningful economic benefits without 
reducing the margin of safety. Similar to other commenters, EMA noted 
that the proposed practice of marking the lowest flashpoint materials 
transported on a CTMV was previously allowed. Industry consistently 
used the identification number with the lowest flash point (typically 
gasoline) for alternating straight loads involving diesel fuel. EMA 
added that there were no recorded safety concerns with this practice. 
Since the removal of the prior identification number marking exception, 
energy marketers have had to implement inefficient workarounds, such as 
load sequencing or running diesel shipments with one empty compartment 
containing gasoline residue. EMA noted that these practices are 
burdensome, inefficient, and costly, and eliminating such 
inefficiencies, as proposed in the NPRM, will produce tangible cost 
savings across thousands of cargo tank operations.\23\
---------------------------------------------------------------------------

    \23\ EMA also requested that PHMSA expand this marking exception 
to petroleum distillate fuels with up to 15 percent ethanol content. 
Petroleum distillate fuels with more than 10 percent ethanol are 
water-miscible materials, while those 10 percent or below are water-
immiscible materials. These two categories are separate entries in 
the ERG and responders need to treat them differently, including 
using different categories of firefighting foam. Expanding the 
marking exception beyond what was proposed in the NPRM would reduce 
safety and potentially put first responders at unnecessary risk. For 
these reasons PHMSA will not be moving forward with this request.
---------------------------------------------------------------------------

2. Stakeholder Concerns With Emergency Response Efforts
    PHMSA received several comments indicating concern with the 
proposed changes regarding the marking of CTMVs containing petroleum 
distillate fuels, including comments from IAFF, IAFC, CVSA, PVA, and 
KHP. In its comments, IAFF stated that PHMSA's proposal would 
intentionally create discrepancies between a vehicle's placarding and 
the contents of the cargo tank. In addition, IAFF stated that failure 
to disclose all hazardous contents will result in firefighters and 
other responders following incorrect emergency response procedures. 
IAFF provided hypothetical operational examples, including a situation 
where a cargo tank marked ``UN1203'' (gasoline) is involved in a fire 
or spill, noting that it could cause firefighters to assume they are 
dealing with gasoline, which has a low flash point and can ignite 
easily. According to IAFF, if the tank instead contains diesel (UN1202 
or NA1993), which requires higher temperatures for ignition, 
firefighters may misinterpret the absence of fire as an indication of 
safety. IAFF further stated that this false sense of security could 
delay deploying suppression agents tailored specifically for diesel. 
IAFF also described a scenario with multi-compartmented cargo tanks 
transporting multiple fuels on separate trips, suggesting that relying 
on the identification number of the lowest flash point fuel--without 
clarity on the actual contents at the time of the incident--could lead 
to confusion

[[Page 1437]]

among emergency responders. According to IAFF, this confusion could 
delay critical containment actions and increase the risk of errors in 
evacuation and decontamination procedures. Lastly, IAFF claimed that 
using water-based agents, which are effective for gasoline fires, but 
not for diesel spills, could exacerbate emergency incidents.
    In its comments, KHP shared views similar to IAFF, stating that 
while UN1203 and NA1993 direct emergency responders to the same ERG 
response procedure, it is important to remember that the ERG is for use 
by first responders during the initial phase of a transportation 
incident involving hazardous materials.
    The IAFC comments also shared concerns about emergency responders, 
stating that PHMSA's proposal aims to simplify processes for shippers 
but overlooks bill of lading requirements (i.e., shipping paper 
requirements). IAFC maintained that the different information provided 
on the shipping paper and the vehicle marking creates confusion for 
first responders. As described above, IAFC stated that correct markings 
are necessary when formulating a proper emergency response action plan 
and, in their view, the rule would have an overall negative impact on 
first responders.
    Finally, PVA echoed IAFF's concerns, stating that vessel operators 
transporting fuels via tank truck or trailer must be able to identify 
quickly the contents to respond effectively to an onboard emergency. 
PVA was concerned this proposal could impede crew members' ability to 
serve as first responders when a shipment is underway or at the dock.
PHMSA Response to Stakeholder Concerns With Emergency Response Efforts
    PHMSA acknowledges the commenters' concerns regarding markings for 
petroleum distillate fuels and the importance of those markings to 
emergency responders. As noted in the NPRM, for NA1993, UN1202, UN1203, 
UN1223, and other petroleum distillate fuels, the ERG directs the 
reader to the same guide page for initial emergency response 
instructions. The ERG is designed to aid emergency responders in their 
initial response to transportation incidents involving hazardous 
materials and groups materials with similar hazards and properties into 
specific ``guides.'' In the case of petroleum distillate fuels, all 
relevant UN numbers direct the reader to Guide 128, meaning that all 
petroleum distillate fuels have identical initial response procedures.
    As mentioned by some commentors, marking and placarding of the 
transport vehicle is not the only form of hazardous materials 
communications that first responders have available to rely on. The HMR 
also require carriers to maintain a shipping paper onboard the vehicle 
which provides the proper shipping name, identification number, and 
hazard class, among other information, of the materials onboard the 
vehicle. First responders will, in most cases, refer to that document 
to confirm the specific material involved.
    PHMSA is unaware of any fire suppression foams that are 
specifically tailored for diesel fuel rather than gasoline. For 
example, readily available literature from a trade association \24\ 
that represents manufacturers of fire suppression equipment, and the 
State of Tennessee,\25\ indicates that Class B foam--both polar and 
non-polar formulations--is effective in fighting fires caused by non-
polar hydrocarbon fuels, like gasoline and diesel fuel. Using this type 
of foam, or a similar one, could address any concerns emergency 
responders might have about the exact contents of the tank. In 
contrast, there are foams specifically tailored for high-ethanol 
content gasoline--gasoline with more than 10 percent ethanol. However, 
PHMSA has specifically excluded ``UN3475, Ethanol and gasoline mixture 
or Ethanol and motor spirit mixture or Ethanol and petrol mixture, with 
more than 10 percent ethanol, 3, PGII'' from this marking exception 
because of the different fire suppression media required for this type 
of material. PHMSA believes that any risks and burdens to emergency 
responders raised by the commenters' hypothetical scenarios are minimal 
and can be mitigated--if not completely eliminated--by responding to 
incidents involving petroleum distillate fuels as highly flammable 
materials.

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

    As previously discussed in the NPRM, the flexibility allowed for 
markings for petroleum distillate fuels was previously permissible 
under the HMR. For approximately 33 years, from the publication of HM-
118 \26\ in 1980 until the publication of HM-219 \27\ in 2013, the HMR 
allowed a cargo tank transporting more than one petroleum distillate 
fuel in different trips to display the identification number for the 
petroleum distillate fuel with the lowest flash point. In that time 
frame, PHMSA is unaware of any increase in the number of hazardous 
materials incidents involving petroleum distillate fuels and resulting 
in injuries to first responders. Similarly, since the unintentional 
removal of the exception in the HM-219 final rule, PHMSA is unaware of 
any decrease in hazardous materials incidents involving petroleum 
distillate fuels and resulting in injuries to first responders.

3. Stakeholder Concerns With Enforcement
    The comments from the KHP expressed opposition to the proposed 
change to section 172.336 for petroleum distillate fuels from a law 
enforcement perspective. The KHP stated that the new marking provision 
will create unnecessary burdens on law enforcement by requiring law 
enforcement to decipher what the tank was hauling on the previous 
business day, which, depending on the day of the week, could have been 
several days prior. The KHP went on to provide an example of an 
extended holiday weekend where the previous business day was four days 
prior. According to the KHP, it is typical for a truck driver not to 
know the previous contents of the tank for various reasons, such as the 
vehicle was driven by someone else on the previous business day or the 
driver just picked up the tank as a contracted carrier.
    The KHP further stated that this uncertainty by the driver would 
lead to increased roadside inspection times and significantly hinder 
the officer from performing his or her duty because commercial vehicle 
inspectors must be certain of violations before recording them on an 
inspection report. The KHP continued that if the inspector is wrong in 
writing up the carrier, it may result in the carrier being erroneously 
taken out of service, in addition to the costs associated with 
reversing the citation, including personnel time to remove violations, 
dismiss citations, or even refund civil penalties.
    Finally, the KHP pointed to a potential conflict with CVSA's out of 
service criteria, which direct law enforcement to take a vehicle marked 
with identification number(s) for material(s) that are not present on 
the vehicle out of service. The commenter notes that CVSA inspection 
bulletin

[[Page 1438]]

#2022-06 \28\ states placards must accurately communicate the hazardous 
materials transported on the vehicle.
---------------------------------------------------------------------------

2022-06--Placards on Flammable and Combustible Liquids (Dec. 14, 
2022), https://cvsa.org/wp-content/uploads/2022-06-Inspection-Bulletin.pdf.
---------------------------------------------------------------------------

    CVSA, the organization that KHP referenced in its comment, also 
submitted comments on the topic of enforcement. CVSA stated that both 
industry and enforcement personnel have adapted to the current marking 
requirements in place and a change at this point would be costly to 
implement, as both enforcement and industry personnel would have to be 
retrained. CVSA did not support making the proposed change at this time 
given what it perceives as the potential risk to first responders 
associated with the change and the fact that industry has largely 
adjusted to the status quo of often-frequent placard changes.
PHMSA Response to Stakeholder Concerns With Enforcement
    As PHMSA stated in the NPRM, law enforcement personnel may use 
shipping paper records to determine whether a cargo tank was used to 
transport petroleum distillate fuel with a lower flashpoint than the 
fuel currently onboard the previous business day. And while there may 
be scenarios where this change could impose an additional burden on law 
enforcement personnel, PHMSA is confident that petroleum distillate 
fuel transporters will have access to the information necessary to 
assist investigators in making appropriate determinations of 
compliance.
    In response to the KHP's concerns regarding extended roadside 
inspection times and potential for incorrect citations, PHMSA expects 
investigators and law enforcement officers to familiarize themselves 
promptly with the identification number marking requirements for 
petroleum distillate fuels. As PHMSA expressed in the NPRM, and 
elsewhere in this rulemaking, the initial emergency response 
instructions for petroleum distillate fuels are the same, should an 
incident occur.
4. Stakeholder Concerns With Training
    The KHP stated that from an instructor's standpoint it is much 
easier to explain to students that the operator of a CTMV must display 
identification numbers for the material currently onboard. The KHP 
further stated that it is difficult for a new student to understand how 
a CTMV can display an identification number for a material that is not 
present on the vehicle and will be particularly difficult for students 
to grasp after listening to instructors spend considerable time in the 
classroom emphasizing that a vehicle must not display an identification 
number for a material it is not carrying.
PHMSA Response to Stakeholder Concerns With Training
    PHMSA appreciates the comments regarding training challenges for 
inspectors and law enforcement, but notes that this concern is not 
unique as PHMSA continuously updates the HMR with new rules on a 
regular basis. While the HMR generally states that no one may represent 
through hazard communication that a hazardous material is present in 
the package, motor vehicle, freight container, or other packaging if 
the hazardous material is not present, it is not uncommon for PHMSA to 
provide exceptions from general requirements if economic benefits can 
be produced while minimizing or limiting any potential negative safety 
impact. For example, a hazardous material that meets the general 
classification criteria for a flammable liquid may be reclassed and 
transported as a combustible liquid under certain conditions. In this 
specific case, the costs of constantly changing the identification 
number marking for each different petroleum distillate fuel having the 
same hazard and requiring the same response in case of emergency 
substantially outweighs the benefit of maintaining each marking and can 
be done while maintaining safety. Any change PHMSA makes requires 
shippers, offerors, first responders, and others in the hazardous 
materials industry to stay up-to-date with the latest regulations, 
including updating any trainings that may no longer be accurate.
5. Stakeholder Concerns With Exposure and Personal Protection Equipment
    The IAFF comments also address concerns about potential exposure 
issues, having claimed that firefighters adjust their personal 
protection equipment (PPE) based on the anticipated hazards of the 
material involved in a given incident. The IAFF claimed that incorrect 
identification of the specific hazardous material involved in an 
incident can result in insufficient PPE, increasing the risk of 
chemical exposure, thermal burns, or inhalation of toxic fumes if the 
substances differ significantly from the identification number 
indicated on the vehicle. For instance, the IAFF asserted that diesel 
(UN1202) presents different exposure risks compared to gasoline, but 
that both might be marked as ``UN1203'' under the proposed rule, which 
could lead to inadequate protective measures.
PHMSA Response to Stakeholder Concerns With Exposure and PPE
    While PHMSA does not regulate the uses of or specifications for 
PPE, PHMSA is unaware of any meaningful differences in PPE requirements 
for incidents involving the various petroleum distillate fuels. In 
reviewing several publicly available safety data sheets for various 
petroleum distillate fuels, PHMSA has found no meaningful variation 
between the different materials in terms of recommended PPE. While 
safety data sheets for the same identification numbers can vary 
depending on the manufacturer, the safety data sheets reviewed by 
PHMSA, such as those for Marathon Petroleum Corporation, for diesel and 
gasoline produced by the same company generally included identical PPE 
recommendations. Furthermore, as previously discussed in this final 
rule, PHMSA's ERG provides the same initial emergency response 
instructions for all petroleum distillate fuels, including recommended 
protective clothing--see Guide 128.\29\ The ERG instructs that 
regardless of the type of petroleum distillate fuel involved, first 
responders should equip themselves with: (1) a positive pressure self-
contained breathing apparatus (SCBA); and (2) structural firefighters' 
protective clothing that provides thermal protection. Provided that 
emergency responders are prepared for an incident involving a petroleum 
distillate fuel, the initial emergency response instructions for the 
marked material should be effective and have no detrimental safety 
impact until the actual material is determined.

IV. Response to NPRM Comments on the Other Final Rule Provisions

    PHMSA received limited comments on the other topics addressed in 
this final rule. These comments are addressed in this section.

A. Electronic Submission of Cargo Tank Facility Registration

    PHMSA proposed to revise paragraph section 107.502(d) to include a 
reference to the electronic method for submitting registration 
statements. One commenter noted that allowing electronic submission of 
cargo tank registration statements could pose cybersecurity risks due 
to the data being collected via

[[Page 1439]]

an online portal as opposed to physical media.\30\ PHMSA appreciates 
the comment and notes that the Federal Motor Carrier Safety 
Administration (FMCSA) already has security measures in place to store 
electronic data safely on more than 750,000 active motor carriers and 
millions of drivers. The same security measures cover the electronic 
acceptance and storage of cargo tank facility registration statements. 
PHMSA is not aware of any instances where FMCSA's data security 
protection measures have failed. Having received no other comments, 
PHMSA is adopting this change as proposed.
---------------------------------------------------------------------------

    \30\ See rulemaking docket, available at: https://www.regulations.gov/comment/PHMSA-2018-0080-0004.
---------------------------------------------------------------------------

B. The Chlorine Institute Publication

    PHMSA proposed to revise section 171.7 to replace the current 
incorporation by reference of CI drawings for PRDs found in section 
171.7(l)(3) and (l)(4) with the entire CI Pamphlet 49 titled, 
Recommended Practices for Handling Chlorine Bulk Highway Transports in 
section 171.7(l)(3). CI Pamphlet 49 includes the use of the Midland 
Type PRD for chlorine cargo tanks in addition to those already 
permitted in section 173.315. CI provided comments in support of 
PHMSA's proposal to adopt CI Pamphlet 49 and reference the standard in 
section 173.315(i)(13).\31\ PHMSA did not receive any other comments on 
this proposal.
---------------------------------------------------------------------------

    \31\ CI previously submitted a petition for rulemaking (P-1712) 
to update the incorporation by reference of Pamphlet 49 to the 2016 
version. However, since CI submitted petition P-1712, Pamphlet 49 
has been updated to a more current version. In its comment, CI 
recommends that PHMSA incorporate by reference Edition 11 (2022) 
instead of Edition 10 (2016).
---------------------------------------------------------------------------

    Updating the incorporation by reference of Pamphlet 49 to the 2022 
version is beyond the scope of this rulemaking. CI may submit a 
petition for rulemaking to further update the incorporation by 
reference of Pamphlet 49. Therefore, PHMSA is adopting the revision to 
incorporate by reference the 2016 version of Pamphlet 49 as proposed.

C. Exception From Security Awareness Training

    PHMSA proposed to revise section 172.704(a)(4) to include hazmat 
employees who only manufacture packagings in the current exception from 
safety training. Further, PHMSA proposed to except any hazmat employees 
who only perform hazmat activities related to packagings (e.g., 
employees who manufacture, repair, modify, recondition, or test 
packagings, and do not offer for transportation or transport hazardous 
materials in commerce) from security awareness training as long as they 
do not perform any other HMR function. PHMSA received no comments on 
this proposal and is adopting the change as proposed. For more 
information on this change please see the section-by-section review 
discussion elsewhere in this document.

D. Reflective Design of Uninsulated Cargo Tanks

    PHMSA proposed to modify the requirement in section 178.337-1(d) 
for uninsulated cargo tanks to be painted, which would allow for the 
use of alternative means of providing reflectivity such as a wrap or 
cover. PHMSA received no comments on this proposal and is adopting the 
change as proposed. For more information on this change please see the 
section-by-section review discussion elsewhere in this document.

E. Use of Video Cameras for Cargo Tank Inspections and Tests

    PHMSA proposed to allow for the use of video cameras or video 
optics equipment for any cargo tank inspection or test. PHMSA received 
no comments on this proposal and is adopting the change as proposed, 
except that the provision is provided in paragraph (a)(7) rather than 
(a)(8). For more information on this change please see the section-by-
section review discussion elsewhere in this document.

V. Section-by-Section Review of Amendments

A. Section 107.502

    Section 107.502 contains the general registration requirements for 
persons who engage in the manufacture, assembly, certification, 
inspection, or repair of a cargo tank or CTMV manufactured under the 
terms of a DOT specification or a special permit. PHMSA proposed to 
revise paragraph (d) to clarify that persons registering with the 
Department may submit their registration electronically through FMCSA's 
existing online portal (https://portal.fmcsa.dot.gov/UrsRegistrationWizard/) or continue to mail a hard copy of their 
registration statement to FMCSA. In this final rule, PHMSA is adopting 
this revision as proposed.

B. Section 171.7

    Section 171.7 contains the list of material incorporated by 
reference into the HMR. PHMSA proposed to revise paragraphs (l)(3) and 
(4) by incorporating by reference CI Pamphlet 49 (Edition 10 (2016)) in 
its entirety, rather than incorporating by reference individual PRD 
design drawings from the document. This has the effect of authorizing 
the Midland Type A-14227-ML PRD design for cargo tanks used in chlorine 
service. In this final rule, PHMSA is adopting the revision as 
proposed.

C. Section 172.303

    Section 172.303 contains prohibitions on the display of markings 
that indicate that a specific hazardous material is present when that 
material is not present in transportation. In response to comments, 
PHMSA is adding an exception in (b)(4) to this general prohibition for 
CTMVs that are marked in accordance with the petroleum distillate fuel 
marking requirements adopted in section 172.336 in this rulemaking. 
This amendment is a conforming amendment to the section 172.336 marking 
exception that allows CTMVs to display the identification number of the 
lowest flash point petroleum distillate fuel transported in the tank on 
that day or the previous business day. This makes it clear to both 
motor carriers and enforcement agencies that a CTMV is allowed to 
display the identification number of the petroleum distillate fuel with 
the lowest flash point transported in the current or previous business 
day. In this final rule, PHMSA is adopting the revision as proposed.

D. Section 172.336

    Section 172.336 outlines special provisions for the display of 
identification numbers. PHMSA proposed to revise the section 172.336(c) 
table, which provides scenarios where identification numbers are either 
not required or an exception applies. The proposal added a sixth row to 
Table 1 to Paragraph (c)--Identification Numbers Are Not Required, to 
authorize the display of the identification number representing the 
petroleum distillate fuel with the lowest flash point that is 
transported in a cargo tank in different trips on the previous or 
current business day. However, due to different emergency response 
procedures, PHMSA also proposed the exception would not be applicable 
when the cargo tank transported gasoline and alcohol fuel blends 
consisting of more than 10 percent ethanol. This is consistent with the 
current requirements in the fifth row of the table. Specifically, PHMSA 
proposed that in this circumstance, the identification numbers ``3475'' 
or ``1987'' must also be displayed, as appropriate, and the cargo tank 
may only display ``3475'' or ``1987'' when

[[Page 1440]]

the material is in the cargo tank. Therefore, if the liquid petroleum 
distillate fuel with the lowest flash point transported in the cargo 
tank in different trips on the previous or current business day was a 
gasoline and alcohol fuel blend consisting of more than 10 percent 
ethanol, and it is not being transported in the cargo tank currently, 
``3475'' or ``1987'' may not be displayed on the cargo tank. In this 
scenario, the cargo tank should display either the identification 
number of the liquid petroleum distillate fuel with the next lowest 
flash point transported in different trips on the previous or current 
business day or the liquid petroleum distillate fuel that is currently 
being transported.
    PHMSA also proposed to specify that the exception in the fifth row 
only applies to compartmented cargo tanks and compartmented tank cars. 
This will distinguish clearly the fifth and sixth row exceptions. The 
fifth row authorizes the display of the identification number of the 
petroleum distillate fuel with the lowest flash point when the cargo 
tank or tank car contains more than one petroleum distillate fuel. The 
fifth-row exception is only possible when the cargo tank or the tank 
car is compartmented--i.e., it has multiple compartments each with a 
different petroleum distillate fuel. Therefore, PHMSA proposed to 
remove the term ``cargo tank'' to indicate clearly the exception only 
applies to ``compartmented cargo tanks or compartmented tank cars.'' In 
this final rule, PHMSA is adopting the revisions to section 172.336 as 
proposed. Refer to Section III. ``Identification Number Markings for 
Petroleum Distillate Fuels'' for further discussion on this issue.

E. Section 172.704

    Section 172.704 contains the training requirements for hazmat 
employees. Currently, paragraph (e)(1) excepts from safety training 
hazmat employees who only repair, modify, recondition, or test 
packagings and who do not perform any other function in the HMR. PHMSA 
proposed to also include hazmat employees who only manufacture 
packagings. Further, PHMSA proposed to except these hazmat employees 
from security awareness training. Security awareness training imposed 
on hazmat employees who only manufacture, repair, modify, recondition, 
or test packagings, and do not perform any other function subject to 
the HMR, does not present the same security benefit as for those hazmat 
employees who offer for transportation, transport, or handle hazardous 
materials. In this final rule, PHMSA is adopting the revisions to 
section 172.704(e)(1) as proposed.

F. Section 173.315

    Section 173.315 describes the requirements for the transportation 
of compressed gases in cargo tanks and portable tanks. Paragraph (i) 
provides cargo tank and portable tank requirements for pressure relief 
devices, with paragraph (i)(13) detailing the specifications for safety 
relief valves on chlorine cargo tanks. PHMSA is revising section 
173.315(i)(13) to replace the reference to specific PRD drawings with a 
general reference to CI Pamphlet 49 for authorized safety relief 
valves. This allows the use of the Midland PRD in addition to the 
Crosby PRD on cargo tanks transporting inhalation hazards to provide 
additional regulatory flexibility without reducing safety. In this 
final rule, PHMSA is adopting the revision to section 173.315 as 
proposed.

G. Section 178.337-1

    Section 178.337-1 contains the general requirements applicable to 
constructing an MC-331 cargo tank designed to transport compressed 
gases. Paragraph (d) addresses the requirement for uninsulated tanks to 
have a reflective metal surface or a reflecting color to limit heat 
transfer to the contents in the tank. PHMSA proposed to remove the 
requirement that the tank be ``painted'' to allow for the use of 
reflective vinyl wraps or other innovative reflective coatings. In this 
final rule, PHMSA is adopting the revision to section 178.337-1(d) as 
proposed.

H. Section 180.407

    Section 180.407 contains requirements for the periodic inspection 
of CTMVs to qualify them for continued hazardous materials service. 
PHMSA proposed to authorize, in a new paragraph (a)(7), the use of 
video cameras and fiber optics equipment for any visual inspection 
required for CTMVs in part 180, subpart E. In this final rule, PHMSA is 
adopting the revision to section 180.407 as proposed. This revision 
allows video cameras or fiber optics equipment to be used for visual 
inspections, provided that all of the required areas and elements that 
need to be tested or inspected can be viewed and evaluated in 
accordance with part 180, subpart E.

VI. Regulatory Analysis

A. Statutory/Legal Authority

    This final rule is published under the authority of Federal 
Hazardous Materials Transportation Act (HMTA; 49 U.S.C. 5101-5127). 
Section 5103(b) of the HMTA authorizes the Secretary of Transportation 
to ``prescribe regulations for the safe transportation, including 
security, of hazardous materials in intrastate, interstate, and foreign 
commerce.'' The Secretary has delegated his authority as granted in the 
HMTA to the PHMSA Administrator in 49 CFR 1.97(b).

B. Executive Order 12866; Regulatory Planning and Review

    Executive Order (E.O.) 12866 (Regulatory Planning and Review), as 
implemented by DOT Order 2100.6B (Policies and Procedures for 
Rulemaking), requires agencies to regulate in the ``most cost-effective 
manner,'' to make a ``reasoned determination that the benefits of the 
intended regulation justify its costs,'' and to develop regulations 
that ``impose the least burden on society.'' \32\ DOT Order 2100.6B 
specifies that regulations should generally ``not be issued unless 
their benefits are expected to exceed their costs.'' In arriving at 
those conclusions, E.O. 12866 requires that agencies should consider 
``both quantifiable measures . . . and qualitative measures of costs 
and benefits that are difficult to quantify'' and ``maximize net 
benefits . . . unless a statute requires another regulatory approach.'' 
E.O. 12866 also requires that ``agencies should assess all costs and 
benefits of available regulatory alternatives, including the 
alternative of not regulating.'' DOT Order 2100.6B directs that PHMSA 
and other Operating Administrations must generally choose the ``least 
costly regulatory alternative that achieves the relevant objectives'' 
unless required by law or compelling safety need.
---------------------------------------------------------------------------

    \32\ See also Dep't of Transportation, DOT Order 2100.7, 
Ensuring Reliance Upon Sound Economic Analysis in Department of 
Transportation Policies, Programs, and Activities (requiring DOT 
rulemaking activities to be based on sound economic principles and 
analysis supported by rigorous cost-benefit analysis).
---------------------------------------------------------------------------

    E.O. 12866 and DOT Order 2100.6B also require that PHMSA submit 
``significant regulatory actions'' to the Office of Information and 
Regulatory Affairs (OIRA) within the Executive Office of the 
President's Office of Management and Budget (OMB) for review. This 
action is a significant regulatory action that was submitted to OIRA 
and OMB for review. Any changes made during E.O. 12866 review have been 
documented in the docket. PHMSA prepared an analysis of the potential 
costs and benefits associated with this action. This analysis, 
Regulatory Impact Analysis for Hazardous Materials: Eliminating

Unnecessary Regulatory Burdens on Fuel Transportation (the ``RIA'') is 
available in the docket.

C. Executive Orders 14192 and 14219

    This final rule is an E.O. 14192 deregulatory action.\33\ PHMSA has 
determined the total costs of the rule to the regulated community will 
be less than zero and estimates annualized net benefits at a seven 
percent discount rate of approximately $145.3 million per year. Details 
on the costs, cost savings, and benefits of this rulemaking can be 
found in the RIA, which is available in the public docket.
---------------------------------------------------------------------------

    \33\ 90 FR 9065 (Jan. 31, 2025).
---------------------------------------------------------------------------

    Overall, the revisions adopted in this rulemaking promote the 
continued safe transportation of hazardous materials while producing a 
net cost savings. Cost savings are derived from allowing the continued 
display of the identification number of the lowest flash point fuel 
transported in a cargo tank motor vehicle in the same or previous 
business day. In addition, PHMSA finds this final rule does not 
implicate any of the factors identified in section 2(a) of E.O. 14219 
indicative of a regulation that is ``unlawful . . . [or] that 
undermine[s] the national interest.'' \34\

D. Executive Order 13132

    PHMSA analyzed this rulemaking in accordance with E.O. 13132 
(Federalism) \35\ and the Presidential Memorandum (Preemption) that was 
published in the Federal Register on May 22, 2009.\36\ E.O. 13132 
requires agencies to assure meaningful and timely input by State and 
local officials in the development of regulatory policies that may have 
``substantial direct effects on the states, on the relationship between 
the national government and the states, or on the distribution of power 
and responsibilities among the various levels of government.''
---------------------------------------------------------------------------

    \35\ 64 FR 43255 (Aug. 10, 1999).
    \36\ 74 FR 24693 (May 22, 2009).
---------------------------------------------------------------------------

    This rulemaking may preempt State, local, and Native American 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.
    The Federal Hazmat Law contains an express preemption provision, 49 
U.S.C. 5125(b), that preempts State, local, and Tribal requirements on 
certain covered subjects, unless the non-Federal requirements are 
``substantively the same'' as the Federal requirements, including:
    (1) Designation, description, and classification of hazardous 
materials;
    (2) Packing, repacking, handling, labeling, marking, and placarding 
of hazardous materials;
    (3) Preparation, execution, and use of shipping documents related 
to hazardous materials and requirements related to the number, 
contents, and placement of those documents;
    (4) Written notification, recording, and reporting of the 
unintentional release in transportation of hazardous material; and
    (5) Design, manufacture, fabrication, marking, maintenance, 
recondition, repair, or testing of a packaging or container 
represented, marked, certified, or sold as qualified for use in 
transporting hazardous material.
    This rule addresses subject items (2) and (5) above, which are 
covered subjects, and, therefore, non-Federal requirements that fail to 
meet the ``substantively the same'' standard are vulnerable to 
preemption under the Federal Hazmat Law. Moreover, PHMSA will continue 
to make preemption determinations applicable to specific non-Federal 
requirements on a case-by-case basis, using the obstacle, dual 
compliance, and covered subjects tests provided in Federal Hazmat Law.

E. Executive Order 13175

    This document was analyzed in accordance with the principles and 
criteria contained in E.O. 13175 (Consultation and Coordination with 
Indian Tribal Governments) and DOT Order 5301.1A (Department of 
Transportation Tribal Consultation Policies and Procedures). Because 
none of the changes in this final rule have Tribal implications or 
impose substantial direct compliance costs on Indian Tribal 
governments, the funding and consultation requirements of E.O. 13175 do 
not apply. In addition, PHMSA notes that it received no comments from 
Native American tribes.

F. Regulatory Flexibility Act and Executive Order 13272

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
agencies to consider whether a rulemaking would have a ``significant 
economic impact on a substantial number of small entities'' to include 
small businesses, small not-for-profit organizations that are 
independently owned and operated and are not dominant in their fields, 
and small governmental jurisdictions with populations under 50,000 
people. The Regulatory Flexibility Act directs agencies to establish 
exceptions and differing compliance standards for small businesses, 
where possible to do so and still meet the objectives of applicable 
regulatory statutes. E.O. 13272 (Proper Consideration of Small Entities 
in Agency Rulemaking) \37\ requires agencies to establish procedures 
and policies to promote compliance with the Regulatory Flexibility Act 
and to ``thoroughly review draft rules to assess and take appropriate 
account of the potential impact'' of the rules on small businesses, 
governmental jurisdictions, and small organizations. The DOT posts its 
implementing guidance on a dedicated web page.\38\

Small Entities (May 18, 2012), available at: https://www.transportation.gov/regulations/rulemaking-requirements-concerning-small-entities.
---------------------------------------------------------------------------

    This rulemaking has been developed in accordance with E.O. 13272 
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. PHMSA has developed a 
final regulatory flexibility analysis (RFA), which is included in the 
docket. As detailed in the RFA, based on a query of FMCSA data and 
Census Bureau data, trucking companies that haul hazardous materials 
possess an average of 3.3 CTMVs. Assuming 85,658 CTMVs will be affected 
by the placarding exemption (see Section 3.1.2 for data and 
calculations), then a figure of 3.3 CTMVs per firm implies that 25,957 
trucking companies will be impacted. Further, assuming the industry 
structure of trucking companies hauling petroleum distillates mirrors 
that of the trucking industry overall, we can conclude that 23,101 
companies (i.e., 89 percent of 25,957) qualify as small businesses 
affected by the placarding exemption. This final rule facilitates more 
efficient movement of hazardous materials by highway and inspection of 
hazardous materials packagings, while ensuring that safety is 
maintained or enhanced. It applies to shippers and carriers of 
hazardous materials as well as entities that inspect hazardous 
materials packaging, some of whom are small entities. The changes 
affected by this rule would relieve the regulatory burdens of U.S. 
companies, including small entities, by removing costly requirements 
that do not contribute to safety. Based on this information, PHMSA 
expects to affect 25,957 small business with annualized cost savings 
per small business of $5,603. As described in the FRFA section of the 
accompanying RIA document (Section

[[Page 1442]]

4), PHMSA has assessed this cost against average industry revenue for 
small trucking entities and concluded that it amounts to 1.22-1.27 
percent of average small entity annual revenues. There is no set 
threshold for determining what constitutes a significant impact, but a 
rule of thumb used by many Agencies is impacts that are over 3 percent 
of annual revenue are likely to be significant. Those above 1 percent 
may be significant in certain instances but may not amount to a 
significant impact. In this case impacts are close enough to the lower 
bound that impacts on small entities are unlikely to be significant. 
The changes are generally intended to provide regulatory flexibility 
and cost savings to industry members, while increasing safety. The FRFA 
asks Agencies to describe actions taken to minimize impacts on small 
entities but in the context of deregulatory cost savings such a mandate 
would tend to disadvantage small entities relative to large and implies 
that beneficial impacts can be considered to be non-significant within 
the context of the RFA. PHMSA did not receive comments on the 
anticipated economic impacts to small entities and the RFA.

G. Paperwork Reduction Act

    Under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.), 
no person is required to respond to any information collection unless 
it has been approved by OMB and displays a valid OMB control number. 
Pursuant to 44 U.S.C Sec.  3506(c)(2)(B) and 5 CFR 1320.8(d), PHMSA 
must provide interested members of the public and affected agencies an 
opportunity to comment on information collection and recordkeeping 
requests.
    PHMSA has analyzed this final rule in accordance with the Paperwork 
Reduction Act. PHMSA did not receive any comments regarding information 
collections associated with the changes adopted in this final rule. In 
addition, some information collections proposed in the NPRM were not 
adopted in this final rule and are therefore excluded.
    Requests for a copy of this information collection should be 
directed to Steven Andrews, Office of Hazardous Materials Standards, 
Pipeline and Hazardous Materials Safety Administration, 1200 New Jersey 
Avenue SE, Washington, DC 20590-0001, 202-366-8553.

H. Unfunded Mandates Reform Act of 1995

    The Unfunded Mandates Reform Act of 1995 (UMRA; 2 U.S.C. 1501 et 
seq.) requires agencies to assess the effects of Federal regulatory 
action on State, local, or Tribal governments, and the private sector. 
For any NPRM or final rule that includes a Federal mandate that may 
result in the expenditure by State, local, and Tribal governments, or 
by the private sector of $100 million or more in 1996 dollars in any 
given year, an agency must prepare, amongst other things, a written 
statement that qualitatively and quantitatively assesses the costs and 
benefits of the Federal mandate.
    This rulemaking does not impose unfunded mandates under UMRA. As 
explained in the RIA, it is not expected to result in costs of $100 
million or more in 1996 dollars on either State, local, or Tribal 
governments, in the aggregate, or to the private sector in any one 
year. This is the least burdensome alternative that achieves the 
objective of the rule.

I. National Environmental Policy Act: Environmental Assessment

1. Introduction
    The National Environmental Policy Act of 1969 (NEPA; 42 U.S.C. 4321 
et seq.), requires Federal agencies to assess and consider the impacts 
on the human and natural environment of their proposed actions. Unless 
a categorical exclusion applies, when a proposed action does not have a 
reasonably foreseeable significant effect on the quality of the human 
environment, or if the significance of such effect is unknown, Federal 
agencies are required to prepare an environmental assessment. If, based 
on the finding of the environmental review, the agency determines not 
to prepare an environmental impact statement (EIS) because the proposed 
action will not have significant effects on the human or natural 
environment, the agency can conclude the NEPA process with a finding of 
no significant impact (FONSI) (42 U.S.C. 4336(b)(2)). PHMSA did not 
consider a categorical exclusion because at the time of the NPRM 
issuance, no categorical exclusion applied. PHMSA is finalizing the 
action based on a completed 2025 Environmental Assessment and 
subsequent Finding of No Significant Impact.
2. Purpose and Need
    The purpose of this final rule is to provide greater clarity and 
regulatory flexibility in the Hazardous Materials Regulations (HMR; 49 
CFR parts 171-180). This final rule reduces unnecessary burdens 
associated with safe transportation of hazardous materials, including 
energy products, in commerce. It revises provisions specific to the 
highway transportation of hazardous materials. The amendments will 
reduce costs on hazardous materials transporters and packaging 
manufacturers while maintaining the high level of safety provided in 
the HMR.
3. Description of Alternatives
3.1 No Action Alternative
    If PHMSA were to select the No Action Alternative, current 
regulations would remain in place, and no new provisions would be 
amended or added. This alternative does not provide the necessary 
amendments to provide greater clarity and regulatory flexibility, nor 
does it address the PIPES Act of 2016 and petitions for rulemaking. 
Thus, the no action alternative does not meet the purpose and need of 
this action.
3.2 Selected Alternative (Final Rule)
    PHMSA is adopting several amendments originally proposed in the 
Notice of Proposed Rulemaking (NPRM) version of this rule.\39\ The 
amendments chosen for adoption are summarized below and more fully 
discussed in the preamble and regulatory text sections of this Final 
Rule.

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

3.3 Alternatives Dismissed From Further Consideration
Proposed Rule Alternative (NPRM)
    PHMSA assessed an alternative that would have finalized the 
requirements as proposed in the NPRM. This alternative includes 
adoption of the 2017 RSAC proposals for rail transportation; revision 
to the approval process for tank car designs and Quality Assurance 
Programs (QAPs); miscellaneous amendments to highway cargo tank 
specification and requalification requirements; and an amendment to 
cargo tank marking requirements for the transportation of petroleum 
distillate fuels. This alternative applies to the transportation of 
hazardous materials by highway, rail, and vessel. The potential 
environmental effects of the NPRM as proposed are described in detail 
in the Draft Environmental Assessment (DEA), which is incorporated here 
by reference.\40\
---------------------------------------------------------------------------

    \40\ 89 FR 85590, Section V.H (Oct. 28, 2024).
---------------------------------------------------------------------------

    PHMSA is no longer considering this alternative and instead is 
moving forward with the six amendments specifically identified in the 
final rule. These amendments were selected because they align with the 
Administration's priorities of unleashing American energy and reducing 
other unnecessary regulatory burdens constraining interstate commerce. 
PHMSA will continue to evaluate the other provisions included in the 
NPRM and may choose to address them at a later date.
4. Affected Environment
    The final rule amends certain provisions of the HMR to increase 
regulatory clarity and consistency; to update requirements to reflect 
changing conditions and trends; and to improve the safe transportation 
of hazardous materials. The final rule would apply to the transport of 
hazardous materials by various transportation modes that occur 
nationwide.
5. Environmental Consequences
5.1 No Action Alternative
    The No Action Alternative would not adopt enhanced and clarified 
regulatory requirements expected to maintain the high level of safety 
in transportation of hazardous materials provided by the HMR. If PHMSA 
were to select the No Action Alternative, the HMR would remain 
unchanged, and no new provisions would be amended or added. There would 
be no new environmental impacts from adopting the No Action 
Alternative, and any additional regulatory clarity and flexibility, 
their associated efficiencies, and economic benefits gained through 
these amendments would not be realized.
5.2 Selected Alternative (Final Rule)
    The changes under the Proposed Action Alternative will maintain the 
high safety standards currently achieved under the HMR. The reasonably 
foreseeable environmental impacts are described by section below.
A. Section 172.336
    PHMSA is revising the identification number marking requirements 
for cargo tanks transporting multiple petroleum distillate fuels in the 
current or previous business day, which is defined as a day that the 
operator of the cargo tank motor vehicle is open and operating in 
commerce. This amendment authorizes a carrier to display the marking of 
the identification number for the petroleum distillate fuel with the 
lowest flashpoint transported in that cargo tank during the current or 
previous business day. For example, a cargo tank used to transport 
gasoline on Day 1, and diesel fuel only on Day 2, may display ``1203'' 
on Day 2, because gasoline has a lower flash point than diesel fuel.
    This change to markings for petroleum distillate fuels was 
previously permissible under the HMR and HM-118 \41\ from 1980 until 
the publication of HM-219 \42\ in 2013. The HMR allowed a cargo tank 
transporting more than one petroleum distillate fuel in different trips 
to display the identification number for the petroleum distillate fuel 
with the lowest flash point. PHMSA's removal of this exception in HM-
219 was unintentional, as discussed in section III.A of the Final Rule. 
PHMSA requested comments related to safety and environmental impacts of 
this amendment in the DEA and received no incident data in the time 
frame the exception was allowed. PHMSA is unaware of any significant 
increase in hazardous materials incidents involving petroleum 
distillate fuels resulting in injuries to first responders in that time 
frame. Similarly, PHMSA is unaware of any decrease in hazardous 
materials incidents involving petroleum distillate fuels resulting in 
injuries to first responders. In addition, PHMSA's Emergency Response 
Guidebook (ERG) provides the same initial emergency response 
instructions for all petroleum distillate fuels (Guide 128).\43\ This 
amendment is discussed in full detail in section III of the Final Rule.
---------------------------------------------------------------------------

    \41\ 45 FR 74640 (Nov. 10, 1980).
    \42\ 78 FR 14702 (Mar. 7, 2013).
    \43\ PHMSA, Emergency Response Guidebook (2024), available at: 
https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/2024-04/ERG2024-Eng-Web-a.pdf.
---------------------------------------------------------------------------

    There is no evidence of an increase in the risk of an incident nor 
a delay in emergency response to incidents as a result of this 
amendment. This amendment would improve efficiency during fuel 
deliveries, as operators would no longer be required to change the 
identification number displayed inside the placard. Thus, there are no 
reasonably foreseeable impacts to the human or natural environment.
B. Part 107 Subpart F
    PHMSA is amending part 107 subpart F of the HMR to allow for 
electronic submission procedures under the cargo tank facility 
registration requirements. This would be in addition to the existing 
procedure of mailing a hard copy of the registration statement to 
FMCSA. This amendment provides flexibility, has no impact on the high 
level of safety provided in the HMR, and has no reasonably foreseeable 
impacts to the human or natural environment.
C. Section 171.7
    PHMSA is amending section 171.7 to replace the current 
incorporation by

[[Page 1444]]

reference of CI drawings with the entire CI Pamphlet 49, which would 
include the use of Midland Type PRD for chlorine cargo tanks in section 
173.315, as Midland manufacturing entered the market after the 
requirements of section 173.315(i) were established. This amendment 
does not delete the specific limitations of the type of PRD authorized, 
and PHMSA will continue to work with CI to develop generally applicable 
specifications for PRDs used on cargo tanks transporting inhalation 
hazards. Thus, this amendment provides regulatory flexibility, 
maintains the current level of safety, and has no reasonably 
foreseeable impacts to the human or natural environment.
D. Section 172.704
    PHMSA is amending section 172.704(a)(4) to remove security 
awareness training for hazmat employees who perform hazmat activities 
related only to packagings. These employees are responsible for 
manufacturing, repairing, modifying, reconditioning, or testing 
packagings and do not offer or transport hazardous materials. PHMSA is 
also expanding the eligibility of hazmat employees excepted from safety 
and security trainings to include package ``manufacturers.'' Though 
these changes broaden the population of persons excepted from safety 
and security awareness training, the primary focus of the training is 
related to the offering or transportation of hazardous materials. This 
amendment will maintain the current level of safety of the HMR and has 
no reasonably foreseeable impacts to the human or natural environment.
E. Section 173.315
    PHMSA is amending section 173.315(i)(13) to conform with the 
changes made in Section 171.7. This change replaces the reference to 
specific PRD drawings with a general reference to CI Pamphlet 49 for 
authorized safety release valves. Similarly to the section 171.7 
amendment, this amendment does not delete the specific limitations of 
the type of PRD authorized. PHMSA will continue to work with CI to 
develop generally applicable specifications for PRDs used on cargo 
tanks transporting inhalation hazards. Thus, this amendment provides 
regulatory flexibility, maintains the current level of safety, and has 
no reasonably foreseeable impacts to the human or natural environment.
F. Section 178.337-1(d)
    PHMSA is amending section 178.337-1(d) to allow the use of other 
external coverings besides paint, such as reflective vinyl wraps, to 
meet reflectivity requirements. Uninsulated tanks are required to have 
a reflective metal surface or a reflecting color to limit heat transfer 
to the contents of the tank. This amendment would still require 
uninsulated MC-311 tanks to be a white, aluminum, or similar reflecting 
color on the upper two-thirds area of the cargo tank. Thus, this 
amendment will provide regulatory flexibility, maintain the current 
level of safety of the HMR, and has no reasonably foreseeable impacts 
to the human or natural environment.
G. Section 180.407(a)(7)
    PHMSA is amending section 180.407(a)(7) to allow for the use of 
video cameras or video optics equipment for cargo tank inspections or 
tests provided that all of the required areas and elements that need to 
be tested or inspected can be viewed and evaluated in accordance with 
part 180 subpart E. Under current regulations, a human must enter a 
cargo tank to inspect the interior visually. There are risks associated 
with the current practice, such as injury from slipping and falling and 
exposure to residual fumes or hazardous materials. This amendment 
allows operators to avoid these risks, while still performing the 
inspections to an equal standard. Thus, this amendment will provide 
regulatory flexibility, maintain the current level of safety of the 
HMR, and has no reasonably foreseeable impacts to the human or natural 
environment.
6. Public Involvement
    PHMSA issued a DEA with the NPRM on October 28, 2024, which 
proposed to revise the HMR to adopt several modal-specific amendments 
to enhance safe transportation of materials in commerce.\44\ These 
include RSAC proposals for rail transportation; revisions to the 
approval process for tank car designs and QAPs; miscellaneous 
amendments to highway cargo tank specification and requalification 
requirements; and an amendment to cargo tank marking requirements for 
the transportation of petroleum distillate fuels.
---------------------------------------------------------------------------

    \44\ 89 FR 85590 (Oct. 28, 2024).
---------------------------------------------------------------------------

    The comment period for the NPRM and DEA closed on April 28, 2025. 
PHMSA received 37 sets of comments, of which nine are relevant to the 
issues addressed in this final rule. Three comments received discussed 
general environmental concepts, none of which are covered by the scope 
of this final rule. No comments were related to the environmental 
effects analysis of the NPRM as described in the DEA. All relevant 
comments are discussed in detail in Section III.C and Section IV of 
this final rule.
7. Agencies and Persons Consulted During the Consideration Process
    PHMSA has coordinated with FAA, FMCSA, FRA, and the United States 
Coast Guard in the development of this rulemaking. The NPRM was also 
made available to other Federal agencies within the interagency review 
process contemplated under E.O. 12866. No E.O. 12866 meetings were 
requested.
8. Finding of No Significant Impact
    Based on the analysis summarized in this EA, RIA, and the 
accompanying final rule, PHMSA finds that the Selected Alternative 
(final rule) will not have a significant impact on the human or natural 
environment. A majority of the amendments are administrative in nature 
and allow for greater regulatory flexibility in the HMR. They will 
reduce unnecessary burdens associated with the safe transportation of 
hazardous materials, including energy products, in commerce and will 
maintain the high level of safety required by the HMR.

J. Privacy Act

    In accordance with 5 U.S.C. 553(c), PHMSA solicits comments from 
the public to inform its rulemaking process. PHMSA posts these 
comments, without edit, including any personal information the 
commenter provides, to www.regulations.gov, as described in the system 
of records notice (DOT/ALL-14 FDMS), which can be reviewed at http://www.dot.gov/privacy. The complete Privacy Act Statement in the Federal

K. Executive Order 13609 and International Trade Analysis

    E.O. 13609 (Promoting International Regulatory Cooperation) \46\ 
requires that agencies must consider whether the impacts associated 
with significant variations between domestic and

[[Page 1445]]

international regulatory approaches are unnecessary or may impair the 
ability of American business to export and compete internationally. In 
meeting shared challenges involving health, safety, labor, security, 
environmental, and other issues, international regulatory cooperation 
can identify approaches that are at least as protective as those that 
are or would be adopted in the absence of such cooperation. 
International regulatory cooperation can also reduce, eliminate, or 
prevent unnecessary differences in regulatory requirements.
---------------------------------------------------------------------------

    \46\ 77 FR 26413 (May 4, 2012).
---------------------------------------------------------------------------

    Similarly, the Trade Agreements Act of 1979 (Pub. L. 96-39), as 
amended by the Uruguay Round Agreements Act (Pub. L. 103-465), 
prohibits Federal agencies from establishing any standards or engaging 
in related activities that create unnecessary obstacles to the foreign 
commerce of the United States. Pursuant to the Trade Agreements Act, 
the establishment of 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 providing for 
safety, and do not operate to exclude imports that meet this objective. 
The statute also requires consideration of international standards and, 
where appropriate, that they be the basis for U.S. standards.
    PHMSA participates in the establishment of international standards 
in order to protect the safety of the American public. PHMSA has 
assessed the effects of this rulemaking to ensure that it does not 
cause unnecessary obstacles to foreign trade. While the rulemaking 
would clarify and elaborate on existing PHMSA regulations, PHMSA 
expects the rulemaking will result in cost savings and greater 
regulatory flexibility for entities engaged in international commerce. 
Accordingly, this rulemaking is consistent with E.O. 13609 and PHMSA's 
obligations under the Trade Agreement Act, as amended.

L. National Technology Transfer and Advancement Act

    The National Technology Transfer and Advancement Act of 1995 (15 
U.S.C. 272 note) directs Federal agencies to use voluntary consensus 
standards in their regulatory activities unless doing so would be 
inconsistent with applicable law or otherwise impractical. Voluntary 
consensus standards are technical standards (e.g., specification of 
materials, test methods, or performance requirements) that are 
developed or adopted by voluntary consensus standard bodies. This 
rulemaking adopts one voluntary consensus standard published by CI that 
is discussed in the discussion on Sec.  171.7. See ``Section IV. 
Section-by-Section Review; Section 171.7'' for further details.

M. Energy-Related Executive Orders 13211, 14154, and 14156

    E.O. 13211 (Actions Concerning Regulations That Significantly 
Affect Energy Supply, Distribution, or Use) \47\ requires Federal 
agencies to prepare a Statement of Energy Effects for any ``significant 
energy action.'' E.O. 13211 defines a ``significant energy action'' as 
any action by an agency (normally published in the Federal Register) 
that promulgates, or is expected to lead to the promulgation of, a 
final rule or regulation that (1)(i) is a significant regulatory action 
under E.O. 12866 or any successor order and (ii) is likely to have a 
significant adverse effect on the supply, distribution, or use of 
energy (including a shortfall in supply, price increases, and increased 
use of foreign supplies); or (2) is designated by the Administrator of 
the Office of Information and Regulatory Affairs (OIRA) as a 
significant energy action.
---------------------------------------------------------------------------

    \47\ 66 FR 28355 (May 22, 2001).
---------------------------------------------------------------------------

    This final rule is not a ``significant energy action'' under E.O. 
13211 because it is not likely to have a significant adverse effect on 
supply, distribution, or energy use. In addition, because this is not a 
``significant energy action'' under E.O. 13211, it is therefore not 
necessary to consider the requirements of E.O. 14154 (Unleashing 
American Energy) \48\ and E.O. 14156 (Declaring a National Energy 
Emergency).\49\ For additional discussion of the anticipated economic 
impact of this rulemaking, please review the RIA in the rulemaking 
docket.

N. Cybersecurity and Executive Order 14028

    E.O. 14028 (Improving the Nation's Cybersecurity) \50\ expressed 
the Administration policy that ``the prevention, detection, assessment, 
and remediation of cyber incidents is a top priority and essential to 
national and economic security.'' E.O. 14028 directed the Federal 
Government to improve its efforts to identify, deter, and respond to 
``persistent and increasingly sophisticated malicious cyber 
campaigns.'' PHMSA has considered the effects of the final rule and has 
determined that its proposed regulatory amendments would not materially 
affect the cybersecurity risk profile for transportation of hazardous 
materials.

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

O. Severability

    The purpose of this final rule is to operate holistically in 
addressing different issues related to safety and environmental hazards 
associated with the transportation of hazardous materials. However, 
PHMSA recognizes that certain provisions focus on unique topics. 
Therefore, PHMSA finds that the various provisions of this rule are 
severable and able to function independently if severed from each 
other. Thus, in the event a court were to invalidate one or more of 
this final rule's unique provisions, the remaining provisions stand and 
continue in effect.
