I. Background 
The Administrative Procedure Act 
requires Federal agencies to give 
interested persons the right to petition an agency to issue, amend, or repeal a rule (See 5 U.S.C. 553(e)). PHMSA’s 
rulemaking procedure regulations (See 
VerDate Sep<11>2014 21:02 Aug 13, 2019 Jkt 247001 PO 00000 Frm 00002 Fmt 4701 Sfmt 4702 E:\FR\FM\14AUP4.SGM 14AUP4khammond on DSKBBV9HB2PROD with PROPOSALS441557 Federal Register / Vol. 84, No. 157 / Wednesday, August 14, 2019 / Proposed Rules 
49 Code of Federal Regulations (CFR) 
106.95) allows persons to ask PHMSA to add, revise, or delete a regulation by filing a petition for rulemaking containing adequate support for the requested action. In this NPRM, PHMSA (also ‘‘we’’ or ‘‘us’’) proposes to amend the HMR in response to petitions for rulemaking submitted by shippers, carriers, manufacturers, and industry representatives. These proposed revisions are intended to reduce regulatory burdens while maintaining, or enhancing, the existing level of safety. We discuss the petitions and proposals in detail in Section II of this NPRM. In this NPRM, PHMSA proposes to: 
•Prohibit after December 31, 2020, 
the use of rail tank cars with shells or heads constructed of non-normalized steel used for transportation of poison- by-inhalation (PIH) materials. 
•Harmonize the limited quantity 
exceptions for more than 100 entries for corrosive materials in the HMT. 
•Revise § 173.302(b)(2) to allow a 
minimum height of 12 mm (0.47 inches) for a proper shipping name marked on a portable tank with a capacity of less than 3,785 L (1,000 gallons). 
•Revise § 173.28(c)(1)(i) to add the 
words ‘‘substantially removed’’ in the context of cleaning metal drums for reuse and clarifying the requisite cleaning standard. 
•Revise § 173.5b to allow for the 
continued use of Portable and Mobile Refrigerator Systems placed into service prior to 1991 that are rated to a minimum service pressure of 250 pounds per square inch (psig). 
•Incorporate by reference updated 
versions of multiple CGA publications. 
•Remove the reference to Special 
Provision 103 in § 172.101 from Column (7) for four HMT entries to allow them to be shipped as safety devices. 
•Revise the HMT entry for ‘‘UN0503, 
Safety Devices, pyrotechnic’’ to allow the shipper to use the exceptions provided in § 173.166(d). 
•Remove the words ‘‘manufactured 
before September 1, 1995’’ from § 180.417(a)(3) to allow for an alternative report for cargo tanks manufactured after September 1, 1985. 
•Revise the basis weight tolerance 
provided in § 178.521 from ±5 percent to ±10 percent from the nominal basis 
weight reported in the initial design qualification test report for paper shipping sacks. 
•Revise § 173.308(d)(3) to harmonize 
with the IMDG Code by removing the requirement for a closed transport container to have the warning mark ‘‘WARNING—MAY CONTAIN EXPLOSIVE MIXTURES WITH AIR— KEEP IGNITION SOURCES AWAY WHEN OPENING’’ when transporting lighters. 
•Make the ‘‘interim’’ rail tank car 
specifications the ‘‘final’’ specifications for the transportation of PIH materials. 
•Prohibit after December 31, 2027, 
the use of certain rail tank cars for the transportation of PIH materials. 
•Allow for all waste materials to be 
managed in accordance with the lab pack exception and associated paragraphs in § 173.12 irrespective of whether they meet the definition of a hazardous waste per the EPA or the RCRA. 
•Incorporate by reference the 2017 
version of the ASME BPVC Sections II (Parts A and B, C and D), VIII (Division 1), and IX into the HMR. 
•Revise §§ 171.23, 173.302, and 
173.304 to permit the import of filled pi- marked foreign pressure receptacles for intermediate storage, transport to point of use, discharge, and export as well as the import of certain pi-marked foreign pressure receptacles filling, intermediate storage, and export. 
•Revise the language in § 173.166 to 
clarify the term ‘‘recycle’’ by adding the word ‘‘metal’’ in front of ‘‘recycling.’’ 
•Correct § 171.7(r) to include the 
address of the IME and to incorporate the IME/Association of Energy Service Companies (AESC) JPG Standard, also known as the ‘‘Guide to Obtaining DOT Approval of Jet Perforating Guns using AESC/IME Perforating Gun Specifications,’’ Ver. 02, dated September 1, 2017 as material incorporated by reference. 
•Update to the January 1, 2018 
version of the APA Standard 87–1, ‘‘Standard for Construction and Approval for Transportation of Fireworks, Novelties, and Theatrical Pyrotechnics’’, which is currently incorporated by reference in § 171.7(f) of the HMR. 
II. Review of Proposed Amendments 1. Phase-Out of Non-Normalized Tank 
Cars Used To Transport PIH Materials 
In its petition (P–1646), AAR 
requested that PHMSA consider an amendment to prohibit the use of rail tank cars with shells or heads constructed of non-normalized steel for transportation of PIH materials. In its petition, AAR states that the use of pressurized tank cars constructed from non-normalized steel for rail transportation of PIH materials poses an unnecessary risk to the public. AAR adds that non-normalized steel is susceptible to brittle fractures at lower temperatures, and brittle fractures are far more likely to result in a catastrophic failure and instantaneous release of a 
car’s entire contents than ductile fractures. While a slow release of contents generally has time to dissipate in the atmosphere, AAR notes that an instantaneous release creates a concentrated toxic cloud with potential catastrophic consequences for the nearby population. AAR has required that tank cars built since 1989 and used in PIH service must be constructed of normalized steel. 
PHMSA believes the phase-out of 
these legacy rail tank cars would have a positive impact on safety due to their replacement with more robust tanks cars used for the transportation of PIH materials. On April 7, 2017, AAR adopted CPC–1325, which implemented a phase-out of these non-normalized (legacy) steel tank cars in PIH service by July 1, 2019. On July 27, 2018, AAR revised CPC–1325 and re-issued it as CPC–1336, but kept the July 1, 2019 phase-out deadline for the non- normalized steel tank cars. CPC–1336 is incorporated into the AAR members’ railroad interchange rules that railroads require compliance with as a condition of shipping hazardous materials by rail. PHMSA proposes to respond to P–1646 by codifying a phase-out of these non- normalized steel tank cars in the HMR that would take effect as of December 31, 2020. PHMSA proposes this date as a general approximation of when this rulemaking is expected to be finalized. However, the AAR phase-out is expected to go into effect regardless of whether PHMSA adopts July 1, 2019, December 31, 2020, or another date into regulation. As a result, there is no cost associated with PHMSA aligning this date as a regulatory deadline. A more detailed discussion of this economic analysis can be found in the 
accompanying PRIA. 
Therefore, PHMSA believes there is 
merit in phasing-out these non- normalized rail tank cars used for the transportation of PIH materials. In this NPRM, PHMSA is proposing to revise § 173.31 to phase-out non-normalized steel rail tank cars for the transportation of PIH materials by December 31, 2020. 
2. Limited Quantity Shipments of 
Hydrogen Peroxide 
In its petition (P–1658), Steris 
requested a revision to the HMT for limited quantities of hydrogen peroxide. Specifically, this petition requests that PHMSA harmonize Column (8A) packaging exceptions for limited quantities of ‘‘UN2014, Hydrogen peroxide aqueous solution,’’ with the UN Model Regulations. Currently, the HMT does not allow the limited quantity exception for UN2014, while 
VerDate Sep<11>2014 21:02 Aug 13, 2019 Jkt 247001 PO 00000 Frm 00003 Fmt 4701 Sfmt 4702 E:\FR\FM\14AUP4.SGM 14AUP4khammond on DSKBBV9HB2PROD with PROPOSALS441558 Federal Register / Vol. 84, No. 157 / Wednesday, August 14, 2019 / Proposed Rules 
various other international standards 
and regulations such as the UN Model Regulations provide for transport of UN2014 in limited quantities, up to 60 percent concentration. Steris argues that harmonizing with the UN Model Regulations would provide economic and logistics consistency in global transport of this material in limited quantities and would facilitate commerce for domestic companies. 
The shipment of limited quantities of 
materials similar to those proposed in this petition is already permitted under the HMR. Therefore, PHMSA believes that expanding the exceptions to these additional materials would not cause a reduction in safety. In addition, because these are exceptions to the HMR, PHMSA would expect cost savings to be achieved if the proposal is finalized. However, due to a lack of national data on these types of shipments, PHMSA was unable to quantify the specific cost savings that would result from this change. A more detailed discussion of this economic analysis of this proposal can be found in the accompanying PRIA. 
Therefore, PHMSA believes there is 
merit in proposing this revision to the HMT. In this NPRM, PHMSA is proposing to revise Column (8A) of the HMT for ‘‘UN2014, Hydrogen peroxide aqueous solution’’ to allow limited quantities packaging exceptions for this material by referencing § 173.152 for exceptions for Division 5.1 oxidizers. 
3. Markings on Portable Tanks 
In his petition (P–1666), William J. 
Briner suggested that the HMR be 
revised, consistent with § 172.302(b)(2) and Section 5.3.2.0.2 of the IMDG Code, to allow a minimum height of 12 mm (0.47 inches) for proper shipping name markings on portable tanks with a capacity of less than 3,000 L (792.52 gallons). The revision would also eliminate confusion about the size of markings on portable tanks, as there is no requirement that they be marked with the proper shipping name under the HMR when they are placarded. 
A technical review of this petition 
found that harmonizing the size of this marking with the IMDG Code would not have a negative effect on safety. While this proposal would allow for smaller markings on portable tanks with a capacity of less than 3,000 L (792.52 gallons), PHMSA is unable to quantify these cost savings as it does not have cost data on the savings gained from using smaller markings and to how many stakeholders they might apply. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. Therefore, PHMSA believes there is 
merit in proposing this revision. 
However, PHMSA believes the size limit of the container should be consistent with the 3,785 L (1,000 gallon) limit currently in this section. In this NPRM, PHSMA is proposing to revise § 172.302(b)(2) to allow that proper shipping name markings on portable tanks with a capacity of less than 3,785 L (1,000 gallons) to be a minimum of 12 mm (0.47 inches). 
4. Reconditioning of Metal Drums 
In its petition (P–1670), RIPA 
requested a revision to § 173.28(c)(1)(i) 
to require that labels be substantially removed, rather than simply removed. RIPA believes that a strict reading of the current regulation asks for an impossible standard, as the full removal of coatings and labels (including their adhesive residues) is practically impossible. RIPA justifies this request by noting that current cleaning and surface preparation processes have been generally accepted for the last 60 years and have never been considered a safety 
issue. 
A technical review of the petition 
found there is no evidence that allowing for minimal amounts of residual glue to remain on a drum after cleaning would have any effect on safety. However, PHMSA asserts that there must be a standard to which the drums are cleaned for the coatings and labels to be considered substantially removed. While this proposal is a relaxation of the requirements in the HMR, PHMSA is unable to quantify these cost savings because it does not have data on the cost differences between ‘‘removed’’ and ‘‘substantially removed,’’ or to how many firms they might apply. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA found that there is 
merit to proposing this revision to the HMR. In this NPRM, PHMSA is also proposing to revise § 173.28(c)(1)(i) to allow tightly adhering paint, mill scale, and rust to remain on no more than 10 percent of each unit’s surface area. 
5. Limited Quantity Harmonization 
In its petition (P–1676), URS 
Corporation requests revisions to 
Column (8A) of the HMT to allow for the shipment of several hazardous materials to be shipped as limited quantities. Specifically, this petition requests that PHMSA harmonize Column (8A) of the HMT for limited quantities for 45 proper shipping names. Currently, the HMT does not allow the limited quantity exception for the materials listed by the petitioner. URS Corporation indicates that if the limited 
quantity exception is not added to the HMT as proposed, then there would continue to be confusion about hazardous materials shipments imported into the United States that are prepared as limited quantity shipments under international regulations. 
A technical review of the petition 
identified a total of 114 entries in HMT that are not in alignment with the UN Model Regulations, including all of those listed in the petition. The review found that 64 of the 114 entries diverge from the International Civil Aviation Organization (ICAO) Technical Instructions for the Safe Transport of Dangerous Goods (ICAO Technical Instructions). The ICAO Technical Instructions permit all 64 entries to be shipped as a limited quantity. The shipment of limited quantities of similar materials is already permitted under the HMR, and expanding the exceptions to these additional materials would not cause a reduction in safety. Because these are exceptions to the HMR, PHMSA would expect cost savings to be achieved if the proposal is finalized. However, due to a lack of national data on these types of shipments, PHMSA was unable to quantify the specific cost savings that would result from this change. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA found there is 
merit to proposing this revision to the HMR. In this NPRM, PHMSA is 
proposing to revise Column (8A) (exceptions) of the HMT consistent with the UN Model Regulations for 114 identified entries. 
6. Mobile Refrigeration Units 
In its petition (P–1677), the IIAR 
requests that PHMSA consider changes 
to § 173.5b for portable and mobile refrigerator systems commonly used in the produce industry. Specifically, this petition proposes to allow the continued use of mobile refrigeration units placed into service prior to 1991 that meet the 250 pounds per square inch (psig) service pressure specification. PHMSA also issued an enforcement discretion memo on September 28, 2017 allowing the continued use of mobile refrigeration units that are tested to a service pressure of 250 psig. 
A technical review of this petition 
found there should be no reduction in safety by allowing the continued use of mobile refrigeration units that are tested to a service pressure of 250 psig. PHMSA believes allowing the continued use of these mobile refrigeration units would allow the agricultural industry to accrue substantial cost savings. In the 
VerDate Sep<11>2014 21:02 Aug 13, 2019 Jkt 247001 PO 00000 Frm 00004 Fmt 4701 Sfmt 4702 E:\FR\FM\14AUP4.SGM 14AUP4khammond on DSKBBV9HB2PROD with PROPOSALS441559 Federal Register / Vol. 84, No. 157 / Wednesday, August 14, 2019 / Proposed Rules 
1Previous edition of this document was titled 
‘‘Guidelines for Visual Inspection and 
Requalification of Low Pressure Aluminum Compressed Gas Cylinders, 1991, First Edition.’’ PRIA, PHMSA estimates there would be 
approximately $1,000,000 in annualized costs savings to the agricultural industry resulting from the continued use of mobile refrigeration units currently in service. A more detailed accounting of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA believes there is 
merit to allowing the continued use of these mobile refrigeration units, under certain conditions. In this NPRM, PHMSA is proposing to revise § 173.5b to allow the continued used of certain portable and mobile refrigerator systems that meet the 250 psig service pressure specification by removing the prohibition of use of refrigeration systems placed into service before June 1, 1991, specified in paragraph (b)(6). 
7. Incorporation by Reference of CGA 
Standards 
Certain CGA standards are 
incorporated by reference in § 171.7 of the HMR. Multiple petitions to update CGA standards were submitted to PHMSA for review. These petitions include: 
•Petition (P–1679)—CGA proposed 
that PHMSA IBR CGA C–6.3, ‘‘Standard for Visual Inspection of Low Pressure Aluminum Alloy Cylinders, 2013, Third Edition’’
1into § 171.7 to replace the 
outdated reference to the First Edition of this standard published in 1991. 
•Petition (P–1680)—CGA proposed 
that PHMSA IBR CGA S–7, ‘‘Method for Selecting Pressure Relief Devices for Compressed Gas Mixtures in Cylinders, 2013, Fifth Edition’’ into § 171.7 to replace the outdated reference to the 2005 Fourth Edition of this standard. 
•Petitions (P–1684) and (P–1693)—In 
two separate petitions, Worthington Cylinders and CGA requested that § 171.7 be updated to include the most recent version of the CGA C–11, ‘‘Practices for Inspection of Compressed Gas Cylinders at Time of Manufacture, 2013, Fifth Edition’’ and that references to the outdated Third Edition of this standard published in 2001 be removed. These petitions also request modifications to § 178.35(b) and (c) to refer to CGA C–11. 
•In petition (P–1694)—CGA 
proposes that PHMSA IBR C–6.1–2013, ‘‘Standards for Visual Inspection of High Pressure Aluminum Compressed Gas Cylinders’’ into § 171.7 of the HMR. This sixth edition of CGA C–6.1–2013 would update and replace current references to the 2002 Fourth Edition. A technical review of these petitions 
found that the IBR of revised standards 
would not result in a reduction in safety and would likely enhance safety. It is important for the HMR to reflect the most recent version of these cylinder IBR documents to ensure the safe transportation of compressed gases. There were no quantifiable cost savings identified with these IBR documents. These IBR revisions are primarily technical in nature and do not have a material effect on the cost of business. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA believes there is 
merit in proposing updates to these IBRs in § 171.7 of the HMR. In this NPRM, PHMSA is proposing to IBR the updated CGA publications in § 171.7 of the HMR. 
8. Special Provision for Explosives 
In its petition (P–1681), the IME 
proposed that PHMSA remove Special 
Provision (SP) 103 from § 172.102, as well as remove references to SP 103 from Column (7) of the HMT for the following entries: ‘‘UN 0361, Detonator assemblies, non-electric, for blasting’’; ‘‘UN 0365, Detonators for ammunition’’; ‘‘UN 0255, Detonators, electric, for blasting’’; and ‘‘UN 0267, Detonators, non-electric, for blasting.’’ 
IME requests this change to 
harmonize the HMR with the UN Model Regulations, which has no provision capping the net explosive mass that may be involved in a limited propagation of detonators within a package classed as Division 1.4B at 25 grams as described 
in SP 103. Detonators must only pass the tests prescribed by the UN MTC to be transported (in this case pass the UN Test Series 6 requirements). The manual contains the criteria, test methods, and procedures used for the classification of dangerous goods (i.e., hazardous 
materials) per the provisions of UN Model Regulations to ensure an appropriate level of safety. Only those detonators that successfully pass tests prescribed for Division 1.4B may be classed in this hazardous materials category. The changes IME requests would align the HMR with the UN Model Regulations. 
A technical review of this petition 
found that the removal of this special provision is necessary to harmonize with the international regulations and would have no effect on safety. Since these special provisions are no longer in wide use, PHMSA does not believe there would be any quantifiable cost savings. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. Therefore, PHMSA believes there is 
merit in removing this special provision 
from the four entries in the HMT. In this NPRM, PHMSA is proposing to remove the references to SP 103 for these four entries in Column (7) of the HMT. Also, because SP 103 is only assigned to these four entries, PHMSA is proposing to delete SP 103 from § 172.102. 
9. EX Numbers and Safety Devices 
In its petition (P–1683), the Ford 
Motor Company requested a change to 
the HMT to remove the word ‘‘None’’ and replace with ‘‘166’’ in Column (8A) for the proper shipping name ‘‘UN 0503, Safety Devices, pyrotechnic.’’ This is a reference to authorized packaging for safety devices found in § 173.166. Ford Motor Company believes this omission prevents the shipper of these devices from applying the requirement to include the EX number on the shipping document as found in § 173.166(c), and does not allow the shipper to use the exceptions provided in § 173.166(d). Ford believes the omission is a typo in the HMT and should be corrected. 
PHMSA’s technical review of this 
petition determined, consistent with the 
Ford Motor Company petition, that the exclusion of ‘‘166’’ in Column 8A of HMT for ‘‘UN 0503, Safety Devices, pyrotechnic’’ was an oversight from a previous rulemaking. There is no reason from a safety perspective why ‘‘UN 0503, Safety Devices, pyrotechnic’’ would not be eligible for shipment as a safety device in accordance with § 173.166. Insufficient data on the number of shipments effected limits PHMSA’s ability to quantify potential cost savings. In addition, it is perhaps likely that industry is already taking advantage of the exceptions in paragraph (d)(1) whenever the situation allows, and existing requirements in § 172.320(b) already require the EX number. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA found there is 
merit to proposing this revision to the HMT. In this NPRM, PHMSA is proposing to remove the word ‘‘None’’ from Column (8A) for the proper shipping name ‘‘UN 0503, Safety Devices, pyrotechnic’’ in the HMT and replace it with ‘‘166’’ to authorize use of packaging requirements for safety devices. 
10. Alternative Reports for Cargo Tanks 
In its petition (P–1685), Polar Service 
Systems proposes revising the HMR to 
allow an alternative report for cargo tanks to replace a missing certificate of compliance for cargo tanks manufactured before September 1, 1995. 
VerDate Sep<11>2014 21:02 Aug 13, 2019 Jkt 247001 PO 00000 Frm 00005 Fmt 4701 Sfmt 4702 E:\FR\FM\14AUP4.SGM 14AUP4khammond on DSKBBV9HB2PROD with PROPOSALS441560 Federal Register / Vol. 84, No. 157 / Wednesday, August 14, 2019 / Proposed Rules 
2The ATCCRP coordinates research efforts to 
enhance the safety and security of rail tank car 
shipments of toxic inhalation hazard (TIH) materials. It is a joint effort comprised of shippers of tank cars carrying TIH materials (represented by ACC, the Chlorine Institute, and the Fertilizer Institute); railroads that transport hazardous materials (represented by AAR); and rail tank car builders and lessors (represented by RSI). For more information, see https://tankcarresourcecenter.com/ wp-content/uploads/2017/11/ATCCRP-Research- Background-2016.pdf. The petition recommends 
accomplishing this by removing the words ‘‘manufactured before September 1, 1995’’ from § 180.417(a)(3). The petitioner indicates that there is currently no provision to allow the use of alternative reports when a certificate of compliance is unavailable for cargo tanks manufactured after September 1, 1995. Some cargo tank manufacturers have gone out of business in the past 20 years, making it impossible for a tank owner to obtain a missing certificate of compliance from the manufacturer. 
PHMSA’s technical review of the 
petition found there are existing problems with maintaining the required documentation of Cargo Tanks and Cargo Tank Motor Vehicles (CTMVs) when manufacturers are no longer in business. This is true irrespective of the date to which alternative documentation is allowed in § 180.417. PHMSA does not believe there would be an effect on safety because the same testing and recordkeeping requirements would apply to manufacturers that could take advantage of this proposed revision. Alternatively, in the absence of this proposed change, packages with useful life remaining could be forced out of service. This petition is not expected to result in any material cost to industry. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA believes there is 
merit to proposing this revision to the HMR. In this NPRM, PHMSA is proposing to revise the language in § 180.417(a)(3) to allow for alternative reports when a manufacturer’s certificate is not available regardless of date of manufacture. 
11. Weight Tolerances for Paper 
Shipping Sacks 
In its petition (P–1688), the Paper 
Shipping Sack Manufacturers Association proposes that PHMSA revise the basis weight tolerances for liners and mediums used in the manufacture of multiwall shipping sacks. Specifically, this petition requests that PHMSA revise the basis weight tolerance provided in § 178.521 from ±5 percent to ±10 percent from the nominal basis weight reported in the initial design qualification test report. The petitioner notes that multiwall sacks are manufactured on the same or technically equivalent machines that manufacture the liners for fiberboard boxes. PHMSA revised the basis weight tolerances from ±5 percent to ±10 percent for fiberboard boxes in the HM– 219A final rule, published on November 7, 2018 [83 FR 55792]. PHMSA’s technical review of this 
petition found that the paper used to 
manufacture paper bags is made on the same machines or similar machines as that used to make fiberboard boxes. Given the technical data presented in the petition, which included linerboard drop and dynamic compression tests, PHMSA concluded that a small reduction (or a nearly infinite increase) in basis weight of the paper used in manufacturing fiberboard boxes does not affect performance, it is expected that paper bags will behave similarly. PHMSA estimates the total potential annualized cost savings to the industry of $20,000 to $200,000. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA found there is 
merit to proposing this revision to the HMR. In this NPRM, PHMSA is proposing to revise § 178.521 to revise the nominal basis weight reported in the initial design qualification test report from ±5 percent to ±10 percent. 
12. Markings on Closed Transport Containers 
In its petition (P–1690), Matson 
proposes that PHMSA amend § 173.308(d)(3) to remove the requirement for a warning to be placed on the access door of a closed transport vehicle or a closed freight container when lighters are transported by vessel. Matson notes that a similar warning is not required by the IMDG Code, meaning that the HMR is not harmonized in this respect. 
As noted above, this requirement is 
only in the HMR and is not required in 
the IMDG Code. PHMSA’s technical review of this petition found that harmonizing this section with the IMDG Code would not result in a reduction in safety. PHMSA believes the existing hazard communication requirements (transport documents, container placard, etc.) provide a sufficient level of safety that is consistent with requirements for other Division 2.1 materials. As the petition eliminates a warning marking requirement and provides regulatory clarity through harmonization, we anticipate no associated costs from this proposal. However, PHMSA was unable to quantify any cost savings associated with this petition. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA found there is 
merit to proposing this revision to the HMR. In this NPRM, PHMSA is proposing to amend the lighter transportation requirement in § 173.308(d)(3) to remove the requirement for vessel transport of a closed transport vehicle or freight 
container to display the warning mark ‘‘WARNING—MAY CONTAIN EXPLOSIVE MIXTURES WITH AIR— KEEP IGNITION SOURCES AWAY WHEN OPENING’’ on the access door. 
13. Finalization of the HM–246 Tank 
Car Standard 
In a joint petition (P–1691), AAR, the 
Chlorine Institute, ACC, the Fertilizer Institute, and RSI request that PHMSA convert certain ‘‘interim’’ rail tank car specifications to ‘‘final’’ tank car specifications. The subject tank car 
specifications were issued as part of the January 13, 2009, final rule entitled ‘‘Improving the Safety of Railroad Tank Car Transportation of Hazardous Materials (HM–246),’’ (74 FR 1769), which was targeted at improving the safe transportation of PIH materials by rail. 
The HM–246 final rule contained 
interim design standards for rail tank cars transporting PIH materials to be used until a permanent standard could be issued by PHMSA. The final rule prescribed enhanced safety measures for PIH materials transported in rail tank cars, primarily stronger tanks with higher tank test pressures, fittings, tank head-puncture resistance protection and, for some commodities, thermal protection. The HM–246 final rule was the result of industry consensus that an updated standard was necessary to improve accident survivability, even as research continued to develop a long- term PIH tank car specification. 
The ATCCRP
2suggests the HM–246 
interim specification provides a significant level of improvement over the legacy designs and there are few additional economical options to improve standards beyond the interim standard. According to the petitioner, PIH tank cars built in compliance with the HM–246 interim standards have performed well in service. In addition, conclusions from the various ATCCRP projects provide scientific support to make the interim specifications permanent. Conclusions resulting from these safety research efforts, as reported by ATCCRP, include: 
•The ‘‘interim’’ standard designs 
finalized in 2009 provide significant

specifications; and 
•No design feature or material was 
identified that would provide a significantly greater level of improvement, or would be a reasonable alternative (from an economic or manufacturability standpoint) that should be required industry-wide. 
PHMSA’s technical review of this 
petition found that the HM–246 compliant rail tank cars have an established safety record with no major incidents attributed to the design of the tank car. The petitioner’s requested changes are not expected to result in any material costs to industry, as the costs of this proposed amendment are already accounted for in the analysis of HM–246 final rule, which adopted the interim tank car standard. A more detailed discussion of this economic 
analysis can be found in the accompanying PRIA. 
Therefore, PHMSA found there is 
merit to proposing this revision to the HMR. In this NPRM, PHMSA is proposing to revise §§ 173.314(c) and 173.244(a)(2) of the HMR to make the HM–246 rail tank car specification permanent for the transportation of PIH materials. 
14. Phase-Out of Non-HM–246 
Compliant Rail Tank Cars 
In 2006, after several major PIH rail 
tank car accidents, AAR began to release a series of CPCs that mandated the use of a safer design for tank cars that transport PIH materials. On March 31, 2008, AAR published CPC–1187 implementing design specifications for tank cars used in PIH service. CPC–1187 also included a 10-year phase-out schedule for tank cars that did not meet the CPC–1187 specification. According to the new AAR standard, non- compliant tank cars would not be accepted for interchange after December 31, 2018. 
On April 1, 2008, PHMSA published 
an NPRM proposing revisions to the HMR to improve the crashworthiness protection of railroad tank cars designed to transport PIH materials. (73 FR 17817). On January 13, 2009, PHMSA issued a final rule establishing the ‘‘Interim HM–246 Standard.’’ (74 FR 1769). The Interim HM–246 Standard effectively adopted AAR’s CPC–1187 tank car specification for the transportation of PIH materials until further research could be completed on enhanced tank car specifications. 
In the NPRM for HM–246, PHMSA 
considered adopting a phase-out of tank cars that did not meet the proposed standard. However, in the HM–246 final rule, PHMSA decided not to adopt a 
phase-out schedule for legacy cars stating, ‘‘[a]lthough we continue to believe that an accelerated phase out of these cars is justified, we recognize the voluntary efforts already underway by many fleet owners to phase out these cars, in many cases on schedules more aggressive than the five-year deadline proposed in the NPRM.’’ (74 FR at 1777–1778). After PHMSA published the HM–246 final rule adopting an interim tank car standard, AAR suspended CPC–1187 until a new tank car standard could be finalized and suspended the December 2018 retirement deadline for non-compliant tank cars. 
As discussed in Section II.13, 
‘‘Finalization of the HM–246 Tank Car Standard,’’ above, research conducted under the ATCCRP has since demonstrated that the HM–246 interim tank car design provides significant improvements in survivability and in their view, no other design would provide significantly greater level of improvement. However, despite initial indications in 2009 that voluntary efforts would result in an accelerated phase-out of those tank cars in PIH service that failed to comply with the HM–246 interim standard, the industry 
had not adopted a voluntary phase-out schedule as of December 2016 that would eliminate less safe tank cars from PIH service. 
On December 16, 2016, AAR 
submitted a petition (P–1692) requesting that PHMSA adopt a six-year phase-out for PIH rail tank cars that do not meet the interim HM–246 specification standard as implemented in the HM– 246 final rule published on January 13, 2009. AAR argued that collaborative research undertaken by industry and government partners (through ATCCRP) over the last seven years has confirmed that HM–246 specification cars have the highest accident survivability rate over other designs and are the most feasible technology to transport PIH materials. 
On April 7, 2017, before PHMSA 
acted on P–1692, AAR adopted CPC– 1325, which implemented a phase-out by July 1, 2023 of any tank car in PIH service that does not comply with the HM–246 interim standard. Prior to AAR’s adoption of CPC–1325, the Fertilizer Institute commented to the petition for rulemaking docket (P– 1692)
3that it opposed AAR’s 
implementation of the July 1, 2023, phase-out schedule arguing, among other things, that DOT has sole authority over hazardous materials packaging and that AAR’s adoption of the phase-out schedule was done without performing a cost-benefit analysis. As a result, the Fertilizer Institute asserted that the phase-out was being implemented without a full understanding of the extent of its potential costs or benefits. Similar comments were relayed to PHMSA by a group of shipper associations during a January 13, 2017 meeting.
4AAR met 
with PHMSA and FRA on August 1, 2017, during which AAR suggested its phase-out schedule did not conflict with DOT regulations and that the phase-out schedule was intended to remove an older, less-safe car design from PIH service.
5PHMSA sees no need to take a 
position on these specific arguments, as they are rendered moot by subsequent actions. However, it is with a view towards this history that PHMSA notified AAR on December 7, 2017, that it was accepting P–1692 and would conduct a ‘‘safety and policy review that will aid in determining whether the HMR should mandate a phase-out period and, if so, what period would ensure safety and protect the public interest.’’
6 
On July 27, 2018, AAR revised CPC– 
1325 and re-issued it as CPC–1336, extending the phase-out schedule for non-HM–246 compliant tank cars from six (July 1, 2023) to ten years (December 31, 2027). On August 15, 2018, the railroads (represented by AAR) and a group of PIH material shippers (represented by ACC, the Chlorine Institute, and the Fertilizer Institute) submitted a joint comment to P–1692 proposing a phase-out date of December 31, 2027, for all non-HM–246 specification rail tank cars. The December 31, 2027, phase-out date would be in lieu of the six-year timeline requested in AAR’s original petition. The joint commenters met with PHMSA on September 6, 2018, and urged PHMSA to act quickly in completing a rulemaking that would adopt the petition’s proposed 10-year phase-out timeline.
7The joint commenters 
contend that codifying the phase-out in the HMR would improve safety and increase market certainty. 
PHMSA believes the phase-out of 
these legacy rail tank cars would have

a positive impact on safety due to their 
replacement with more robust tanks cars used for the transportation of PIH materials and that regulatory certainty could foster market certainty. PHMSA proposes to respond to P–1692 by codifying the 10-year phase-out schedule in the HMR; however, the phase-out is expected to go into effect under railroad interchange rules regardless of whether PHMSA adopts this date into regulation. As a result, there is no cost associated with PHMSA promulgating this date as a regulatory deadline for the phase-out. 
As such, PHMSA believes there is 
merit in proposing the phasing-out of all non-HM–246 rail tank cars for use in the transportation of PIH materials. In this NPRM, PHMSA proposes to revise § 173.31 to phase-out all non-HM–246 rail tank cars for the transportation of PIH materials by December 31, 2027. PHMSA encourages stakeholder comments assessing the potential impacts of the proposed phase-out and whether the proposed phase-out period in this NPRM is an appropriate timeframe. 
15. Allow Non-RCRA Waste To Use Lab 
Pack Exception 
In its petition (P–1695), Veolia 
requests that PHMSA amend § 171.8 by adding a definition of ‘‘waste material.’’ The purpose of this petition is to allow for all waste material, whether or not it meets the definition of a hazardous waste according to the EPA’s RCRA, to be managed in accordance with the lab packs exception and associated paragraphs in § 173.12. Currently, lab packs in § 173.12 provide relief for ‘‘waste materials’’ that are being offered for disposal and recovery; this has been clarified by PHMSA to only apply to ‘‘hazardous wastes’’ as defined by the EPA. Veolia believes this does not reflect the intention of the regulation, 
and that adding a definition would resolve the issue. 
PHMSA’s technical review of the 
petition supports the petitioner’s interpretation. When PHMSA codified § 173.12, the intention was to apply it to all waste materials, and was not specific to ‘‘hazardous wastes.’’ PHMSA believes that clarifying this intention to include all waste would not lead to a reduction in safety. There are no costs that are expected based on the adoption of this petition. The lab pack exception offers flexibility for transporting waste materials, but does not require changes to business operations or changes to how the waste material is ultimately handled. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. Therefore, PHMSA believes there is 
merit in this proposal. In this NPRM, 
PHMSA is proposing to allow waste materials, irrespective of whether they meet the definition of a EPA/RCRA hazardous waste to be shipped under § 173.12 by adopting a definition of waste material. 
16. Incorporation of ASME Code 
Sections II, VIII, and IX 
In its petition (P–1700), Trinity 
Containers requests that PHMSA IBR the 2017 version of the ASME BPVC, Sections II (Parts A and B, C and D), VIII (Division 1), and IX into the HMR. The ASME BPVC is a standard for the design and construction of boilers and pressure vessels. The petitioner indicates that if changes are not made, ASME Code certificate holders will be in violation of the HMR for manufacturing cargo tanks, non-specification tanks, and implements of husbandry to the ASME Code referenced in § 171.7. 
PHMSA’s technical review of this 
petition found that for certificate holders to remain in compliance with ASME, they must follow this latest 
edition of the ASME Code. Currently, the HMR IBRs the 2015 edition which is already causing issues with compliance if manufacturers or repair facilities choose to use the latest edition of the ASME Code. Adopting the latest version of the ASME Code would ensure that the HMR remains consistent with the best practices used by the industry. A review of PHMSA’s Civil Penalty Action Reports between 2015 and 2016 revealed no citations that were like the example provided by the petitioner. This suggests that these types of citations are infrequent, and that the cost-savings associated with this petition would be modest. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA believes there is 
merit in this proposal. Note that ASME Code Section V (nondestructive examination) is incorporated by reference in the HMR but that ASME Code Section II, Parts C and D are not. In this NPRM, PHMSA is proposing to IBR the latest version of the ASME BPVC Sections II (Parts A and B), V, VIII (Division 1), and IX. 
17. Import of Foreign Pi-Marked 
Cylinders 
In its petition (P–1701), CGA requests 
that PHMSA modify §§ 171.23, 173.302, and 173.304 to permit the transportation of filled pi-marked foreign pressure receptacles that comply with applicable ADR requirements. Pi-marked pressure receptacles are currently allowed to be imported through special permits and 
approvals. P–1701 requests authorization for import, immediate storage, transport to point of use, discharge, and export, as well as the import of empty pi-marked foreign pressure receptacles for filling, immediate storage, and export. In an addendum to the P–1701 petition, Entegris requests additional revisions to §§ 171.23(a) and 173.302(a)(2) to explicitly ensure that the proposed rulemaking is applicable to adsorbed gas packages. The changes to § 171.23(a)(3) requested by Entegris are intended to allow for domestic sourcing as well as import of empty pi-marked pressure receptacles for filling and export. 
PHMSA’s technical review did not 
find any evidence to suggest that there would be any changes with respect to risk and safety resulting from this proposed regulatory change. The shipping of pi-marked cylinders has been allowed for many years through special permits. There is limited available market data on the current export of pi-marked cylinders. The information provided by the petitioner suggests that adopting the proposed amendment would not result in a change to the number of pi-marked cylinders that are transported or the risk profile of the cylinder transportation. Cost savings are expected to be minimal, resulting primarily from the potential time savings for industry and governments due to the elimination of the need for a special permit or approval. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA believes there is 
merit in this proposal. In this NPRM, PHMSA is proposing to modify §§ 171.23, 173.302, and 173.304 to permit the import of filled pi-marked foreign pressure receptacles for storage incidental to movement, transport to point of use, discharge, and export. PHMSA is also proposing to permit the transportation of pi-marked foreign pressure receptacles for export, including filling and storage incident to movement. In addition, PHMSA is proposing to revise §§ 171.23(a) and 173.302(a)(2) to explicitly ensure that the proposed authorization for pi- marked cylinders is applicable to adsorbed gas packages. Finally, to align with similar ADR provisions, and increase shipper and carrier awareness of the requirements for pi-marked cylinders, we are proposing to require a notation on the shipping paper following the basic description of the hazardous material certifying 
compliance with the pi-marked cylinder requirements. PHMSA is also proposing

to IBR the ADR and European Union 
(EU) ‘‘Directive 2010/35/EU of the European Parliament and of the Council’’ into § 171.7 of the HMR. 
18. Placement of the Word ‘‘Stabilized’’ 
in Shipping Description 
In its petition (P–1706), Evonik 
requested that PHMSA clarify how the 
word ‘‘stabilized’’ should appear when providing the shipping description for a hazardous material. There is currently disharmony between the IMDG Code and the HMR that causes confusion with respect to materials that required the word ‘‘stabilized’’ to appear in the proper shipping name. The HMR does not allow the word ‘‘stabilized’’ to appear as part of the proper shipping name. The IMDG Code requires it in 
certain instances. The petitioner claims that this causes needless discrepancies for international shipments under the IMDG Code. 
PHMSA’s technical review found that 
hazardous materials that have some instability but are not specifically identified or classified as self-reactive substances or organic peroxides currently cannot be shipped in compliance with both the HMR and the IMDG Code. This disharmony causes problems with transportation documents. 
Amending the HMR to allow the use 
of the word ‘‘stabilized’’ in the proper shipping name may require manufacturers and shippers to cover labor costs related to training and ensuring compliance with this new requirement. To the extent that these costs exist, they are expected to be negligible. This is because affected entities that engage in international commerce are expected to already be aware of the requirement, and would simply need to know that international and domestic shipments of stabilized materials can be treated the same on the shipping paper. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA believes there is 
merit in this proposal. In this NPRM, PHMSA is proposing to revise § 172.101(c) to clarify that the word ‘‘stabilized’’ can be added as part of the proper shipping name. 
19. Incorporation by Reference of an 
IME Standard 
In its petition (P–1710), IME 
requested that PHMSA incorporate by reference the IME/AESC JPG Standard, also called the ‘‘Guide to Obtaining DOT Approval of Jet Perforating Guns using AESC/IME Perforating Gun Specifications,’’ Version 02, dated September 1, 2017. IME notes that JPGs use shaped explosive charges to 
produce a high-pressure jet that penetrates the liner or casing of a wellbore in order to enhance production of oil and gas wells. Testing of early JPG systems in 2007 suggested the potential for JPGs to improve flow performance by 35 percent. In addition to the IBR, IME proposes that PHMSA include a new § 173.67 to outline exceptions for Division 1.1 JPGs subject to this new IBR material. 
The IME JPG Standard has been used 
since 2008 by PHMSA to aid in the review of EX approval applications for articles meeting the JPG Standard templates as either 1.1D or 1.4D. The standard includes parameters for 13 JPG designs and requires that the individual energetic components (e.g., detonation 
cord, shaped charges, explosive transfer device, etc.) be individually approved. IBR of this standard into the HMR would help to ensure the safe and efficient transportation of JPGs, and provides adequate safety protocols for the transportation of JPGs. 
The economic analysis suggests 
potential annualized cost savings of approximately $360,000 for manufacturers of JPGs compliant with the IME/AESC Standard. Additional cost savings are expected for both manufacturers and PHMSA due to reduced labor requirements for processing applications for EX approvals. A more detailed discussion of this economic analysis can be found in the accompanying PRIA. 
Therefore, PHMSA believes there is 
merit in this proposal. In this NPRM, 
PHMSA is proposing to incorporate this standard into § 171.7 of the HMR and include a new § 173.67 to outline exceptions for Division 1.1 JPGs subject to this new IBR material. 
20. Incorporation by Reference of an 
APA Standard 
In its petition (P–1711), the APA 
requested PHMSA update references in the HMR to incorporate the new version of APA Standard 87–1, ‘‘Standard for Construction and Approval for Transportation of Fireworks, Novelties, and Theatrical Pyrotechnics,’’ which is currently incorporated by reference in § 171.7(f)(1) of the HMR. The APA states that this 2001 edition of the standard needs to be updated, because of advances in the fireworks industry over the last 15 years. For consumer fireworks, new devices have been developed including combination devices, and more devices now contain multiple tubes and combinations of effects that were previously limited to single tubes. The petitioner elaborates that these new products do not fit into the existing classification system under the current standard. 
The National Fireworks Association 
(NFA) submitted a letter in opposition to this petition. The NFA is a domestic fireworks trade organization with 1,200 members. In the letter, NFA states that proposed changes have a substantial impact on the fireworks industry and, in particular, small businesses. In the letter of opposition, NFA states that the proposed action ‘‘imposes new restrictions, prohibitions, and specifications that do not exist under the current standard.’’ In a letter to its members, NFA provides an explanation of its opposition letter. NFA states that although the revised 87–1A standard has ‘‘many good updates, including new design categories that would make EX approvals easier for some items,’’ the updated standard also includes restrictions that are inconsistent with industry practices. 
PHMSA is choosing to propose to IBR 
the new APA standard despite NFA’s opposition to the petition. NFA objected to PHMSA accepting the APA petition on the assertion that the APA petition lacked the information described in § 106.100(b) of the HMR. This section only states that PHMSA may require more information to evaluate a petition for rulemaking; it is not required. In the case of P–1711, PHMSA determined that additional information was not necessary to accept the petition for rulemaking. The revised APA 87–1 is expected to provide clarity to the fireworks industry, while maintaining the composition limits developed by PHMSA for classification that are needed to ensure the safe transportation of fireworks. Furthermore, PHMSA’s decision to propose IBR the revised APA standards was informed by its review of the explicit requirements for consumer fireworks in APA 87–1A, display fireworks in APA 87–1B, and professional fireworks (classed as articles pyrotechnics) in APA 87–1C. These standards add numerous new devices, expand the permitted chemical list, and focus solely on hazard classification for transportation. However, PHMSA will consider comments on whether we should move forward with incorporating this standard in a final rule. PHMSA estimates that adoption of this petition would provide an annualized cost savings of approximately $270,000 to industry, through expanding the approval process to reduce testing requirements for theatrical pyrotechnics. A more detailed discussion of this economic analysis can be found in the accompanying PRIA.

PHMSA believes there is merit in this 
proposal. Therefore, PHMSA is 
proposing to incorporate this updated standard into § 171.7 of the HMR. However, PHMSA is seeking comments on both what is proposed in the APA petition and comments submitted by the NFA on the merits of this proposal.

III. Section-by-Section 
Below is a section-by-section 
description of the changes being 
proposed in this NPRM. 
A. Appendix A to Subpart D, Part 107 
Appendix A to Subpart D, of Part 107 
sets forth the guidelines PHMSA uses 
(as of October 2, 2013) in making initial baseline determinations for civil penalties. In this NPRM, PHMSA is proposing to update the references to the APA documents to reflect the proposed new versions of the 87–1 Standard. 
B. Section 107.402 
Section 107.402 outlines how to 
submit an application for designation as 
a certification agency. PHMSA is proposing to update a reference to the APA documents to reflect the proposed new version of the 87–1 Standard in § 107.402(d). 
C. Section 171.7 
Section 171.7 lists all standards 
incorporated by reference into the HMR 
that are not specifically set forth in the regulations. In this NPRM, PHMSA is proposing to IBR the following publications by APA, ASME, CGA, and IME: 
1. European Agreement concerning 
the International Carriage of Dangerous Goods by Road, 2017, into § 171.23. The ADR outlines the European regulations concerning the international carriage of dangerous goods by road within the EU, and this publication presents the European Agreement, the Protocol Signatures, the annexes, and the amendments. The ADR can be found at https://www.unece.org/trans/danger/ publi/adr/adr_ e.html. 
2. Directive 2010/35/EU of the 
European Parliament and of the council, June 16, 2010, into § 171.23. 
The aim of Directive 2010/35/EU of the European Parliament and of the Council on Transportable Pressure Equipment (2010 TPED) is to promote the free movement of transportable pressure equipment (TPE) within the European Community (EC). This directive provides for a legal structure whereby TPE can be manufactured, sold, and

restricted chemicals. A copy of this 
standard can be found in this rulemaking docket at https://www.regulations.gov/ docket?D=PHMSA-2017-0120. 
D. Section 171.8 
Section 171.8 defines terms generally 
used throughout the HMR that have 
broad or multi-modal applicability. PHMSA is proposing to add a definition for ‘‘waste material’’ to allow wastes that do not meet the EPA/RCRA definition of hazardous waste to be managed in accordance with the lab pack exception and associated 
paragraphs in § 173.12. 
E. Section 171.23 
Section 171.23 covers the 
requirements for specific materials and 
packagings transported under the ICAO Technical Instructions, IMDG Code, Transport Canada TDG Regulations, or the IAEA Regulations. PHMSA is proposing to revise § 171.23(a)(3) to allow for the use of pressure vessels and pressure receptacles that are marked with a pi mark in accordance with the European Directive 2010/35/EU on transportable pressure equipment (TPED) and that comply with the requirements of Packing Instruction P200, P208 and 6.2.2 of ADR concerning PRD use, test period, filling ratios, test pressure, maximum working pressure, and material compatibility for the lading contained or gas being filled. This proposal would allow for intermediate storage, transport to point of use, discharge, and export of pi-marked cylinder. 
F. Section 172.101 
The HMT is contained in § 172.101. 
The HMT lists alphabetically, by proper 
shipping name, those materials that have been designated hazardous materials for the purpose of transportation. It provides information used on shipping papers, package marking, and labeling, as well as other pertinent shipping information for hazardous materials. In this NPRM, PHMSA is proposing to amend the HMT in the following ways. 
PHMSA is proposing to remove 
reference to SP 103 from Column (7) of the HMT for the following four explosive entries ‘‘UN0361, —Detonator assemblies, non-electric, for blasting’’; ‘‘UN0365, —Detonators for ammunition’’; ‘‘UN0255, —Detonators, electric, for blasting’’; and ‘‘UN0267, —Detonators, non-electric, for blasting.’’ PHMSA is also proposing to remove the word ‘‘None’’ from Column (8A) for the entry ‘‘UN0503, Safety Devices, pyrotechnic’’ and replacing it with a reference to § 173.166 (‘‘166’’). Finally, PHMSA is also proposing to revise 114 entries to harmonize the limited quantity exceptions in Column (8A) with the ICAO Technical Instructions and the UN Model Regulations. 
G. Section 172.102 
Section 172.102 lists special 
provisions applicable to the 
transportation of specific hazardous materials. Special provisions contain packaging requirements, prohibitions, and exceptions applicable to particular quantities or forms of hazardous materials. Consistent with the § 172.101 Column (7) revisions to ‘‘UN0361, —Detonator assemblies, non-electric, for blasting’’; ‘‘UN0365, —Detonators for ammunition’’; ‘‘UN0255, —Detonators, electric, for blasting’’; and ‘‘UN0267, —Detonators, non-electric, for blasting,’’ in this NPRM, PHMSA is proposing to remove SP 103 as it would no longer apply to any HMT entry. 
H. Section 172.302 
Section 172.302 describes the general 
marking requirements for bulk 
packagings. In this NPRM, PHMSA is proposing to revise the minimum size of the marking requirement on portable tanks in § 172.302(b)(2). This revision would require a minimum marking of 12 mm (0.47 inch) in height. The minimum size requirement would apply to portable tanks with capacities less than 3,785 L (1,000 gallons). 
I. Section 173.5b 
Section 173.5b authorizes the 
transportation by highway of residual 
amounts of Division 2.2 refrigerant gases or anhydrous ammonia contained in non-specification pressure vessels that are components of refrigeration systems. PHMSA is proposing to remove paragraph (b)(6) to indefinitely allow the use of refrigeration systems placed into service prior to June 1, 1991 under specified conditions. 
J. Section 173.28 
Section 173.28 outlines the 
requirements for the reuse, 
reconditioning and re-manufacture of packagings. PHMSA is proposing to modify language in § 173.28(c)(1)(i) to clarify requirements for reconditioning metal drums. PHMSA is proposing to revise § 173.28(c)(1)(i) to read: ‘‘Cleaning to base material of construction, with all former contents and internal and external corrosion removed, and any external coatings and labels sufficiently substantially removed to the extent that tightly adherent paint, mill scale, and rust remain on no more than 10 percent of each unit’s surface area.’’ 
K. Section 173.31 
Section 173.31 outlines the 
requirements for shipping hazardous 
materials in tank cars. In this NPRM, PHMSA is proposing to prohibit the use of tank cars that were manufactured using non-normalized steel for head or shell construction for the transportation of PIH materials after December 31, 2020. PHMSA is also proposing the phase-out of all non-HM–246 compliant tank cars for the transportation of PIH materials by December 31, 2027. 
L. Section 173.56 
Section 173.56 outlines the 
definitions and procedures for the 
classification and approval of a new explosive. PHMSA is proposing to add a reference to a new paragraph in § 173.67, which would apply to exceptions for Division 1.1 JPGs. 
M. Section 173.59 
Section 173.59 outlines the 
description of terms for explosives. 
PHMSA is proposing to update a reference to the APA documents in the definition for consumer firework. 
N. Section 173.64 
Section 173.64 outlines the 
exceptions for Division 1.3 and 1.4 
fireworks. PHMSA is proposing to update a reference to the APA documents in § 173.64(a)(1) and (3). 
O. Section 173.65 
Section 173.65 outlines the 
exceptions for Division 1.4G consumer 
fireworks. PHMSA is proposing to update a reference to the APA documents in § 173.65(a)(1), (a)(3)(i), and (a)(4)(iv). 
P. Section 173.67 
PHMSA is proposing to add a new 
§ 173.67 to outline exceptions for 
Division 1.1 JPGs. 
Q. Section 173.151 
Section 173.151 outlines exceptions 
for Class 4 materials. PHMSA is 
proposing to edit the limited quantities provisions in this section to present limited quantities in appropriate SI units in liters in addition to kilograms. 
R. Section 173.244 
Section 173.244 outlines the 
requirements for bulk packaging for 
certain pyrophoric liquids, dangerous when wet (Division 4.3) materials, and poisonous liquids with inhalation hazards (Division 6.1). PHMSA is proposing to modify the list of

authorized tank car specifications in the 
table of PIH materials (§ 173.244(a)(2)) by replacing the last specification delimiter ‘‘I’’ with ‘‘W’’ to reflect the change of the interim tank car standard to a permanent standard. 
S. Section 173.302 
Section 173.302 outlines the 
requirements for the filling of cylinders 
with nonliquefied (permanent) compressed gases or adsorbed gases. In this NPRM, PHMSA is proposing to revise § 173.302(a)(1) to refer to exceptions in § 171.23(a)(3) for the importation of pi-marked cylinders. PHMSA is also proposing to revise § 173.302(a)(2) to allow adsorbed gases the exceptions provided in § 171.23(a)(3). 
T. Section 173.304 
Section 173.304 outlines the 
requirements for the filling of cylinders 
with liquefied compressed gases. In this NPRM, PHMSA is proposing to revise § 173.304(a) to refer to exceptions in § 171.23(a)(3) for the importation of pi- marked cylinders. 
U. Section 173.308 
Section 173.308 outlines the 
requirements for the shipment of 
lighters. In this NPRM, PHMSA is proposing to delete § 173.308(d)(3), which requires a closed transport vehicle or closed freight container being transported by vessel to contain the marking, ‘‘WARNING—MAY CONTAIN EXPLOSIVE MIXTURES WITH AIR— KEEP IGNITION SOURCES AWAY WHEN OPENING.’’ 
V. Section 173.314 
Section 173.314 outlines the 
requirements for transporting 
compressed gases in tank cars and multi-unit tank cars. PHMSA is proposing to modify the table in § 173.314(c), which lists the authorized tank car specifications for specific compressed gases. The changes replace the last specification delimiter ‘‘I’’ with ‘‘W’’ to reflect the change of the interim HM–246 tank car specification standard for PIH materials to a permanent standard. W. Section 178.35 
Section 178.35 prescribes the 
manufacturing and testing specifications for cylinders used for the transportation of hazardous materials in commerce. PHMSA is proposing to modify § 178.35(b) and (c) to clarify inspection requirements as stipulated in CGA C– 11. 
X. Section 178.521 
Section 178.521 prescribes the 
requirements for paper bags used as 
non-bulk packagings for hazardous materials. In this NPRM, PHMSA is proposing to revise § 178.521(b)(4) to allow for a weight tolerance of ±10 percent from the nominal basis weight reported in the initial design qualification test report instead of ±5 percent. 
Y. Section 179.22 
Section 179.22 specifies additional 
marking requirements for tank cars. In 
this NPRM, PHMSA is proposing to modify § 179.22(e) to replace the letter ‘‘I’’ with the letter ‘‘W’’ to facilitate making the interim HM–246 tank car specification standards permanent for the transportation of PIH materials by rail. 
Z. Section 180.417 
Section 180.417 prescribes the 
reporting and record retention 
requirements pertaining to cargo tanks. Currently § 180.417(a)(3)(i) and § 180.417(a)(3)(ii) allow the use of alternative reports when a manufacturer’s certificate and related papers are not available for DOT specification cargo tanks that were manufactured before September 1, 1995. PHMSA is proposing to remove the provision that limits alternative reports to those DOT specification cargo tanks ‘‘manufactured before September 1, 1995’’ from § 180.417(a)(3). 
IV. Regulatory Analyses and Notices A. Statutory/Legal Authority for This 
Rulemaking 
This rulemaking is published under 
the authority of Federal Hazardous Materials Transportation Law (Federal hazmat law; 49 U.S.C. 5101 et seq.), 
which 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 the authority granted in the Federal Hazardous Materials Law to the PHMSA Administrator at 49 CFR 1.97. This rulemaking proposes to amend several sections of the HMR in response to 24 petitions for rulemaking received from the regulated community. 
B. Executive Order 12866 and DOT 
Regulatory Policies and Procedures 
Background 
In this NPRM, PHMSA is responding 
to 24 petitions that have been submitted 
by the public in accordance with the Administrative Procedure Act (5 U.S.C. 553(e)) and PHMSA’s rulemaking procedure regulations (49 CFR 106.95). Overall, this rulemaking maintains the continued safe transportation of hazardous materials while producing a net cost savings. PHMSA’s findings are summarized here and described in further detail in the preliminary Regulatory Impact Analysis (PRIA), which can be found in the regulatory docket (Docket ID: PHMSA–2017–0120) at www.regulations.gov. 
Summary of Findings 
PHMSA estimates a present value of 
quantified net cost savings of approximately $1.74 million annualized at a 7 percent discount rate. These estimates do not include non-monetized and qualitative cost/cost savings discussed in the PRIA. 
PHMSA’s cost/cost savings analysis 
relies on the monetization of impacts for four petitions included in this rulemaking. All of these petitions have 
annualized cost savings. The following table presents a summary of the four petitions that would have monetized impacts upon codification and contribute to PHMSA’s estimation of quantified net cost savings.

In addition to these four items, 
PHMSA described an additional 19 
items that are deregulatory in nature but lack of monetization of their cost savings impacts. While information gaps prevent quantification of cost savings for these items, PHMSA believes that they provide relief from unnecessary requirements or provide additional flexibility, and therefore should be considered deregulatory in nature. 
Conclusion 
In conclusion, this NPRM is not 
considered a significant regulatory 
action within the meaning of Executive Order 12866 (E.O. 12866) and DOT policies and procedures. See 44 FR 
11034 (Feb. 26, 1979). PHMSA made this determination by finding that the economic effects of this regulatory action would not have an effect on the economy that exceeds the $100 million annual threshold defined by E.O. 12866 and that the regulatory action is not otherwise significant. PHMSA estimates a present value of quantified net cost savings of approximately $25 million over a perpetual time horizon and $1.74 million annualized at a 7 percent discount rate. Please see the PRIA in the regulatory docket for additional detail and a description of PHMSA’s methods and calculations. 
C. Executive Order 13771 
This proposed rule is expected to be 
an E.O. 13771 deregulatory action. 
Details on the estimated cost savings of this proposed rule can be found in the rule’s economic analysis. 
D. Executive Order 13132 
This rulemaking was analyzed in 
accordance with the principles and 
criteria contained in Executive Order 13132 (‘‘Federalism’’) and the presidential memorandum (‘‘Preemption’’) that was published in the Federal Register on May 22, 2009 
[74 FR 24693]. Executive Order 13132 requires agencies to assure meaningful 
and timely input by State and local officials in the development of regulatory policies that may have ‘‘substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various 
levels of government.’’ This rulemaking may preempt State, local, and Tribal requirements, but does not propose any regulation that has substantial direct effects on the States, the relationship between the national government and the States, or the distribution of power and responsibilities among the various levels of government. Therefore, the consultation and funding requirements of Executive Order 13132 do not apply. 
The Federal hazmat law (49 U.S.C. 
5101–5128) contains an express preemption provision [49 U.S.C. 5125(b)] that preempts State, local, and Indian tribal requirements on the following subjects: 
(1) The designation, description, and 
classification of hazardous materials; 
(2) The packing, repacking, handling, 
labeling, marking, and placarding of hazardous materials; 
(3) The preparation, execution, and 
use of shipping documents related to hazardous materials and requirements related to the number, contents, and placement of those documents; 
(4) The written notification, 
recording, and reporting of the unintentional release in transportation of hazardous material; and 
(5) The design, manufacture, 
fabrication, marking, maintenance, 
recondition, repair, or testing of a packaging or container represented, marked, certified, or sold as qualified for use in transporting hazardous material. 
This proposed rule addresses covered 
subject items above and preempts State, local, and Indian tribe requirements not meeting the ‘‘substantively the same’’ standard. This proposed rule is necessary to provide cost savings and regulatory flexibility to the regulated community. This rulemaking proposes to address 24 petitions for rulemaking submitted by the regulated community. PHMSA invites those with an interest in the issues presented in this NPRM to comment on the effect that the adoption of specific proposals may have on State or local governments. 
E. Executive Order 13175 
This rulemaking was analyzed in 
accordance with the principles and 
criteria contained in Executive Order 13175 (‘‘Consultation and Coordination with Indian Tribal Governments’’). Executive Order 13175 requires agencies to assure meaningful and timely input from Indian tribal government representatives in the development of rules that significantly or uniquely affect Tribal communities by imposing ‘‘substantial direct compliance costs’’ or ‘‘substantial direct effects’’ on such communities or the relationship and distribution of power between the Federal Government and Indian tribes. PHMSA does not view this rulemaking as having substantial tribal implications. Therefore, the funding and consultation requirements of Executive Order 13175 do not apply. 
However, we invite Indian tribal 
governments to provide comments on the costs and effects that this or a future rulemaking could potentially have on Tribal communities. 
F. Regulatory Flexibility Act, Executive 
Order 13272, and DOT Procedures and Policies 
The Regulatory Flexibility Act (RFA), 
as amended by the Small Business Regulatory Flexibility Fairness Act of 1996, requires Federal regulatory agencies to prepare an Interim Regulatory Flexibility Analysis (IRFA) for any NPRM subject to notice-and- comment rulemaking under the Administrative Procedure Act unless the agency head certifies that the rule would not have a significant economic impact on a substantial number of small entities. While PHMSA expects that this proposed rule would facilitate new technologies or other changes that provide safety equivalence at lower cost, streamline or reduce recordkeeping and other paperwork and reporting requirements, and address other changes to reduce the regulatory burden of the hazardous materials regulations (HMR), PHMSA has limited data on how the proposed rule would impact small entities. Therefore, PHMSA prepared an IRFA which is available in the docket for the rulemaking. 
G. Paperwork Reduction Act 
This NPRM does not impose new 
information collection requirements. 
Depending on the results of our request

for comments to this NPRM, there may 
be a decrease in the annual burden and costs under OMB-proposed changes to incorporate provisions contained in certain widely used or longstanding special permits with an established safety record. 
PHMSA specifically requests 
comments on the information collection and recordkeeping burdens associated with developing, implementing, and maintaining these requirements for approval under this NPRM. 
Address written comments to the 
Dockets Unit as identified in the 
ADDRESSES section of this NPRM. We 
must receive comments regarding information collection burdens prior to the close of the comment period identified in the 
DATES section of this 
NPRM. 
H. Regulation Identifier Number (RIN) 
A regulation identifier number (RIN) 
is assigned to each regulatory action 
listed in the Unified Agenda of Federal Regulatory and Deregulatory Actions (‘‘Unified Agenda’’). The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN number contained in the heading of this document can be used to cross-reference this action with the Unified Agenda. 
I. Unfunded Mandates Reform Act 
This proposed rule does not impose 
unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. It does not result in costs of $160.8 million or more, adjusted for inflation, to either State, local, or tribal governments, in the aggregate, or to the private sector in any one year, and is the least burdensome alternative that achieves the objective of the rule. 
J. Environmental Assessment 
The National Environmental Policy 
Act, 42 U.S.C. 4321–4375, requires 
Federal agencies to analyze proposed actions to determine whether the action would have a significant impact on the human environment. The Council on Environmental Quality (CEQ) regulations require Federal agencies to conduct an environmental review considering: (1) The need for the proposed action; (2) alternatives to the proposed action; (3) probable environmental impacts of the proposed action and alternatives; and (4) the agencies and persons consulted during the consideration process. 
Need for the Proposed Action 
In response to petitions for 
rulemaking submitted by the regulated 
community, PHMSA proposes to amend the Hazardous Materials Regulations 
(HMR; 49 CFR parts 171–180) to update, clarify, or provide relief from miscellaneous regulatory requirements. Specifically, PHMSA is proposing amendments that include, but are not limited to, the following: Incorporating by Reference (IBR) multiple publications from both the CGA, IME, the American Society of Mechanical Engineers (ASME) and the APA; Phase- out of non-normalized steel for transportation of PIH materials, harmonizing the limited quantity exceptions for more than 100 entries for corrosive materials in the HMT, allowing for the continued use of 
Portable and Mobile Refrigerator Systems placed into service prior to 1991 that are rated to a minimum service pressure of 250 pounds per square inch (psi), revising the basis weight tolerance for paper shipping sacks, and allowing non-EPA waste to be managed in accordance with the Lab Pack exception. 
These amendments are intended to 
promote safety and provide clarity and regulatory relief. The proposed changes were identified in response to petitions from stakeholders affected by the HMR. These proposed minor changes would clarify the HMR and enhance safety, while offering some net economic benefits. 
This action is necessary to: (1) Fulfill 
our statutory directive to promote transportation safety; (2) fulfill our statutory directive under the Administrative Procedure Act 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 eliminate unnecessary burdens on the regulated community; (4) address safety concerns raised by petitioners and remove identified regulatory ambiguity; and (5) simplify and clarify the regulations in order to promote understanding and compliance. 
These regulatory revisions would 
offer more efficient and effective ways of achieving the PHMSA goal of safe and secure transportation, protecting both people and the environment, of hazardous materials in commerce. 
Alternatives 
In proposing this rulemaking, PHMSA 
is considering the following 
alternatives: 
Alternative 1: No Action 
If PHMSA chose this alternative, it 
would not proceed with any rulemaking 
on this subject and the current regulatory standards would remain in effect. This option would not address 
outstanding petitions for rulemaking. We rejected the no action alternative. 
Alternative 2: Go Forward With the 
Proposed Amendments to the HMR in This NPRM 
This alternative is the current 
proposal as it appears in this NPRM, applying to transport of hazardous materials by highway, rail, vessel, and aircraft. The proposed amendments encompassed in this alternative are more fully addressed in the preamble and regulatory text sections of the NPRM. 
Probable Environmental Impacts of the 
Alternatives 
When developing potential regulatory 
requirements, PHMSA evaluates those requirements to consider the environmental impact of each amendment. Specifically, PHMSA evaluates the: Risk of release and resulting environmental impact; risk to human safety, including any risk to first 
responders; longevity of the packaging; and if the proposed regulation would be carried out in a defined geographic area, the resources, especially any sensitive areas, and how they could be impacted by any proposed regulations. The regulatory changes proposed in this rulemaking have been determined to be clarification, technology/design updates, harmonization, regulatory flexibility, standard incorporation, or editorial in nature. As such, these amendments have little or no impact on: The risk of release and resulting environmental impact; human safety; or longevity of the packaging. None of these amendments would be carried out in a defined geographic area, i.e., this is 
a nationwide rulemaking. 
Alternative 1: No Action 
If PHMSA were to select the No 
Action Alternative, current regulations 
would remain in place, and no new provisions would be added. However, efficiencies gained through harmonization in updates to transport standards, lists of regulated substances, definitions, packagings, markings requirements, shipper requirements, modal requirements, etc., would not be realized. Foregone efficiencies in the No Action Alternative also include freeing up limited resources to concentrate on hazardous materials transportation issues of potentially much greater environmental impact. Not adopting the proposed environmental and safety requirements in the NPRM under the No Action Alternative would result in a lost opportunity for reducing negative environmental and safety-related

impacts. Greenhouse gas emissions 
would remain the same under the No Action Alternative. Alternative 2: Go Forward With the 
Proposed Amendments to the HMR in This NPRM: 
The Preferred Alternative 
encompasses enhanced and clarified 
regulatory requirements, which would result in increased compliance and 
fewer negative environmental and safety impacts. The table below summarizes the possible environmental benefits, and any potential negative impacts, for the amendments proposed in the NPRM.

Agencies Consulted 
This NPRM 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 from the following Federal Agencies and modal partners: 
•Federal Aviation Administration 
•Federal Motor Carrier Safety 
Administration 
•Federal Railroad Administration 
•U.S. Coast Guard 
PHMSA did not receive any adverse 
comments on the amendments proposed 
in this NPRM from these Federal Agencies. 
Conclusion 
The proposed 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 proposed amendments, if adopted, would foster a greater level of compliance with the HMR because they offer clarity and regulatory flexibility, making it easier for the regulated community to comply with the HMR. Accordingly, the net environmental impact of this proposal would be slightly positive. 
The provisions of this proposed rule 
build on current regulatory requirements to enhance the transportation safety and security of shipments of hazardous materials transported by highway, rail, aircraft and vessel, thereby reducing the risks of an accidental or intentional release of hazardous materials and consequent environmental damage. PHMSA believes that there are no non-negligible environmental impacts associated with this proposed rule. 
PHMSA welcomes any views, data, or 
information related to environmental impacts that may result if the proposed requirements are adopted, as well as possible alternatives and their environmental impacts. 
K. Privacy Act 
In accordance with 5 U.S.C. 553(c), 
DOT solicits comments from the public 
to better inform its rulemaking process. DOT posts these comments, without edit, including any personal information the commenter provides, to http://www.regulations.gov, as described in 
the system of records notice (DOT/ALL– 14 FDMS), which can be reviewed at http://www.dot.gov/privacy. 
L. Executive Order 13609 and 
International Trade Analysis 
Under Executive Order 13609, 
‘‘Promoting International Regulatory Cooperation,’’ agencies must consider whether the impacts associated with significant variations between domestic and international regulatory approaches are unnecessary or may impair the ability of American business to export and compete internationally. See 77 FR 
26413 (May 4, 2012). 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. This proposed rule does

not negatively impact international 
trade. 
M. Executive Order 13211 
Executive Order 13211 (‘‘Actions 
Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use’’) [66 FR 28355; May 22, 2001] requires Federal agencies to prepare a Statement of Energy Effects for any ‘‘significant energy action.’’ Under the executive order, a ‘‘significant energy action’’ is defined 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 (including a notice of inquiry, ANPRM, and NPRM) that: (1)(i) Is a significant regulatory action under Executive Order 12866 or any successor order, and (ii) is likely to have a significant adverse effect on the supply, distribution, or use of energy; or (2) is designated by the Administrator of the Office of Information and Regulatory Affairs as a significant energy action. 
PHMSA does not anticipate that this 
rulemaking would result in significant energy action, but welcomes any data or information related to energy impacts that may result from this NPRM, as well as possible alternatives and their energy impacts. Please describe the impacts 
and the basis for the comment. 
N. 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 standards bodies. This NPRM involves multiple voluntary consensus standards which are listed in § 171.7.

Notes: 1. The percent filling density for liquefied gases is hereby defined as the percent ratio of the mass of gas in the tank to the mass of 
water that the tank will hold. For determining the water capacity of the tank in kilograms, the mass of 1 L of water at 15.5 °C in air is 1 kg. (the 
mass of one gallon of water at 60 °F in air is 8.32828 pounds). 
2. The liquefied gas must be loaded so that the outage is at least two percent of the total capacity of the tank at the reference temperature of 
46 °C (115 °F) for a noninsulated tank; 43 °C (110 °F) for a tank having a thermal protection system incorporating a metal jacket that provides an 
overall thermal conductance at 15.5 °C (60 °F) of no more than 10.22 kilojoules per hour per square meter per degree Celsius (0.5 Btu per hour/ 
per square foot/per degree F) temperature differential; and 41 °C (105 °F) for an insulated tank having an insulation system incorporating a metal 
jacket that provides an overall thermal conductance at 15.5 °C (60 °F) of no more than 1.5333 kilojoules per hour per square meter per degree 
Celsius (0.075 Btu per hour/per square foot/per degree F) temperature differential. 
3. The requirements of § 173.24b(a) apply. 
4. The gas pressure at 54.44 °C (130 °F.) in any non-insulated tank car may not exceed 7⁄10of the marked test pressure, except that a tank 
may be charged with helium to a pressure 10 percent in excess of the marked maximum gas pressure at 54.44 °C (130 °F.) of each tank. 
5. The liquid portion of the gas at ¥17.77 °C (0 °F.) must not completely fill the tank. 
6. The maximum permitted filling density is 125 percent. The quantity of chlorine loaded into a single unit-tank car may not be loaded in ex-
cess of the normal lading weights nor in excess of 81.65 Mg (90 tons). 
7. 89 percent maximum to 80.1 percent minimum at a test pressure of 6.2 Bar (90 psig). 8. 59.6 percent maximum to 53.6 percent minimum at a test pressure of 7.2 Bar (105 psig). 9. For a liquefied petroleum gas, the liquefied gas must be loaded so that the outage is at least one percent of the total capacity of the tank at 
the reference temperature of 46 °C (115 °F) for a noninsulated tank; 43 °C (110 °F) for a tank having a thermal protection system incorporating a 
metal jacket that provides an overall thermal conductance at 15.5 °C (60 °F) of no more than 10.22 kilojoules per hour per square meter per de-
gree Celsius (0.5 Btu per hour/per square foot/per degree F) temperature differential; and 41 °C (105 °F) for an insulated tank having an insula-
tion system incorporating a metal jacket that provides an overall thermal conductance at 15.5 °C (60 °F) of no more than 1.5333 kilojoules per 
hour per square meter per degree Celsius (0.075 Btu per hour/per square foot/per degree F) temperature differential. 
10. For liquefied petroleum gas and anhydrous ammonia, during the months of November through March (winter), the following reference tem-
peratures may be used: 38 °C (100 °F) for a noninsulated tank; 32 °C (90 °F) for a tank having a thermal protection system incorporating a metal 
jacket that provides an overall thermal conductance at 15.5 °C (60 °F) of no more than 10.22 kilojoules per hour per square meter per degree 
Celsius (0.5 Btu per hour/per square foot/per degree F) temperature differential; and 29 °C (85 °F) for an insulated tank having an insulation sys-
tem incorporating a metal jacket and insulation that provides an overall thermal conductance at 15.5 °C (60 °F) of no more than 1.5333 kilojoules 
per hour per square meter per degree Celsius (0.075 Btu per hour/per square foot/per degree F) temperature differential. The winter reference temperatures may only be used for a tank car shipped directly to a consumer for unloading and not stored in transit. The offeror of the tank must inform each customer that the tank car was filled based on winter reference temperatures. The tank must be unloaded as soon as possible after March in order to retain the specified outage and to prevent a release of hazardous material which might occur due to the tank car becoming liq-uid full at higher temperatures. 
11. For materials poisonous by inhalation, the single unit tank car tanks authorized are only those cars approved by the Tank Car Committee 
for transportation of the specified material and built prior to March 16, 2009. 
12. Except as provided by paragraph (d) of this section, for materials poisonous by inhalation, fusion-welded tank car tanks built on or after 
March 16, 2009 used for the transportation of the PIH materials noted, must meet the applicable authorized tank car specification and must be equipped with a head shield as prescribed in § 179.16(c)(1).
