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

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

Marking Requirements for Poison-by- 
Inhalation Materials (P–1591) 
Air Products and Chemicals, Inc. 
submitted a petition (P–1591) requesting that PHMSA amend the marking requirements for poison-by-inhalation hazard (PIH) materials that are shipped in accordance with the IMDG Code or Transport Canada’s Transportation of Dangerous Goods (TDG) Regulations. Specifically, the petitioner requested that PHMSA modify § 171.23(b)(10)(iv)(A) and (B) to remove the phrase ‘‘regardless of the total quantity contained in the transport vehicle or freight container’’ in both paragraphs to align part 171, subpart C requirements for use of international regulations with the poisonous hazardous material marking requirements in § 172.313(c), which offers exceptions based on Hazard Zone, quantity, and number of distinct materials. 
Subpart C of part 171 specifies 
requirements for shipments offered for transportation or transported in the United States under international regulations. For PIH material, subparagraphs (A) and (B) of § 171.23(b)(10)(iv) require that the transport vehicle or freight container must be marked with the identification numbers for the hazardous material, regardless of the total quantity contained in the transport vehicle or freight container, in the manner specified in § 172.313(c) [i.e., the HMR] 
and placarded as required by subpart F of part 172. The petitioner stated that the phrase ‘‘regardless of the total quantity contained in the transport vehicle or freight container’’ gives the appearance that the identification number marking requirement is applicable to any quantity, the remainder of the sentence states that the marking must be ‘‘in the manner specified in § 172.313(c) of this subchapter,’’ which provides an entirely different requirement. 
Section 172.313(c) specifies marking 
requirements for non-bulk packages of PIH material contained in transport vehicles or freight containers subject to certain provisions and limitations. Section 172.313(c)(2) states, the transport vehicle or freight container is loaded at one facility with 1,000 kg (2,205 pounds) or more aggregate gross weight of the material in non-bulk packages marked with the same proper shipping name and identification number, meaning that unless this criteria is met, marking the identification number on the transport vehicle or freight container is not required. The petitioner indicated that the inconsistency of §§ 171.23(b)(10)(iv)(A) and (B) and 172.313(c) is a source of confusion. 
Air Products and Chemicals, Inc. also 
identified a potential discrepancy when transporting internationally to or from the United States in accordance with § 171.23, as the requirement to mark all quantities of PIH material is more restrictive and costly than the current marking requirements for the same materials when transported domestically under the HMR in accordance with § 172.313(c). The petitioner points out that under both the IMDG and the TDG there are no additional marking requirements for transport units carrying PIH materials in non-bulk packages similar to the provisions found in § 172.313(c). Therefore, for quantities of PIH materials in non-bulk packages (less than 1,000 kg per UN number), all three regulations are not aligned. 
The petitioner states that it has had 
numerous shipments of PIH materials frustrated because of this confusing requirement and that the additional marking causes economic hardship and transit delays due to additional labor necessary to apply the extra UN identification numbers at the port. Air Products and Chemicals, Inc. provided neither a specific cost figure for these frustrated shipments nor the anticipated net savings of a regulatory change. 
In the NPRM, PHMSA stated that the 
intent of the requirements in § 171.23(b)(10)(iv) is to provide hazard communication for international shipments of PIH materials transiting the United States under either the IMDG Code or the TDG equivalent to those established in the HMR, not to impose more restrictive requirements. The removal of the phrase referring to a ‘‘total quantity’’ will reduce potential confusion due to differences in inspection interpretations, handling costs, and transit time while maintaining an acceptable level of hazard communication for PIH materials. Therefore, PHMSA proposed to amend § 171.23(b)(10)(iv)(A) and (B) by removing the phrase ‘‘regardless of the total quantity contained in the transport vehicle or freight container’’ from each subparagraph. 
In the NPRM, PHMSA solicited 
comment on the safety implications of such a change, as well as the net benefit (e.g., a decrease in the number of 
frustrated shipments). We received only positive comments on this proposal. Air Products and Chemicals, Inc. supported the proposed change and commented: 
The safety of transporting PIH materials 
will actually be improved with this proposed regulation change. The effectiveness of 
hazard communication will not be reduced as the current UN marking requirement (for all quantities) provides no additional benefit from a hazard communication or emergency response perspective. What we do see is elimination of confusion and a requirement that would be much more consistent with the IMDG and TDG regulations, as well. We understand the importance of consistency between the regulations. Consistency goes a long way in eliminating confusion, especially in an emergency response situation when effective accurate communication is extremely important. The display of UN ID numbers on a transport vehicle for small individual quantities falsely gives the impression that there are large amounts of the hazardous material. In an Emergency Response situation, it is not wise to cause reactions that are based on a representation 
of a large quantity, when in fact, there is no large quantity. Effective emergency response is based both on knowledge of the hazards and knowledge of the quantity. The more consistency we have for hazard communication processes, the better. 
The DGAC also supported the proposed 
change and commented: 
This revision will eliminate confusion 
between the requirements for domestic 
shipments and international shipments. In addition, this revision is consistent with the goal to harmonize domestic regulations with the international requirements. 
For these reasons, we are revising 
§ 171.23(b)(10)(iv)(A) and (B) as 
proposed in the January 23, 2015 NPRM. 
Emergency Response Telephone 
Number (P–1597) 
The DGAC submitted a petition 
(P–1597) requesting that PHMSA amend the emergency response telephone number requirements to prohibit the use of alphanumeric telephone numbers and only permit numeric telephone numbers since, currently, the HMR does not specifically limit the telephone numbers to be numeric under § 172.604(a). The DGAC stated that although telephone faces historically associated integers with letters (e.g., 2
ABC), this is no longer 
the case in all instances. As a result, emergency response telephone numbers presented alphanumerically could cause undesirable delays in acquiring emergency response information in time-sensitive situations as the first responder would have to first convert letters to numbers. 
The DGAC further noted that PHMSA 
issued a letter of interpretation (Ref. No. 04–0032) confirming that alphanumeric presentation of an emergency response telephone number was acceptable but expressing concern about the delays it may cause. 
In the NPRM, PHMSA proposed the 
revision to § 172.604(a) as outlined in 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00006 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335489 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
the petition and noted that the 
continued use of alphanumeric telephone numbers could cause unnecessary delays in emergency response situations. Additionally, PHMSA solicited comment on the cost implications of the proposed revision and, as a result, received four comments from AAR, ACA, ATA, and DGAC in support of this revision. The ATA commented that this revision will decrease chances of death or injury to transporters and emergency responders and that any minimal costs associated with transposing a number from its corresponding letter will be more than outweighed by the safety benefits. The ATA also noted that this revision will be beneficial to both non-English speakers and those unfamiliar with the traditional correspondence between numbers and letters on a telephone keypad. For these reasons, in this final rule we are revising § 172.604(a) as proposed in the January 23, 2015 NPRM. 
Packaging Requirements for Nitric Acid 
(P–1601) 
The UPS submitted a petition 
(P–1601) requesting that PHMSA revise the packaging requirements for ground shipments of nitric acid basing the petition on four loading and sorting operation incidents that occurred over a six-month period. The incidents did not result in any casualties, but varying degrees of property damage were assessed in each situation. The UPS noted that each incident involved the same packaging configuration—glass inner packagings within fiberboard outer packagings—and in each case, a breach of one or more inner packagings caused leakage, resulting in fumes, followed by the initiation of a fire involving the fiberboard outer packaging material. The UPS believes that the 
packaging requirements of the HMR applicable to ground shipments of nitric acid do not adequately address the hazards present. 
As provided in § 173.158, packaging 
for ground shipments of nitric acid prescribe either outer packaging that is not reactive to contents or a combination packaging that includes non-reactive intermediate packaging and absorbent material. However, for concentrations of less than 90 percent nitric acid, the HMR permits the use of glass inner packagings of less than 2.5 L placed inside UN Specification 4G, 4C1, 4C2, 4D, or 4F outer packagings. This latter configuration is associated with the four incidents referenced by UPS in its petition for rulemaking. 
The UPS proposed that PHMSA 
change § 173.158(e) to enhance the packaging requirements applicable to 
nitric acid in concentrations less than 90 percent. Under the proposal in P–1601, when in wooden or fiberboard outer packaging, glass inner packagings used in the configuration prescribed in § 173.158(e) would be required to be packed in tightly-closed, non-reactive intermediate packagings and cushioned with a non-reactive absorbent material. The UPS feels that the addition of this intermediate packaging would properly address the hazards present in this concentration of nitric acid and would have prevented the above incidents from occurring. 
In the NPRM, PHMSA proposed to 
require in § 173.158(e) that when nitric acid, in concentrations less than 90 percent, is placed in glass inner packagings to be packaged in wooden or fiberboard outer packaging, the glass inner packagings must be packed in tightly-closed, non-reactive intermediate packagings and cushioned with a non- reactive absorbent material. In addition, PHMSA solicited comment on whether or not the proposed packaging should be applied to other similar materials as well as on cost burdens from the increase in packaging requirements. PHMSA received four comments from ATA, James Scott, UPS, and Veolia in support of the proposed revision. Veolia commented that it is company policy to place the inner 2.5 L glass bottles in a poly pail intermediate packaging or the outer container must include a leak- proof poly liner, further stating that they have implemented the use of the additional intermediate packages as an additional precautionary safety measure to contain leaking nitric acid, should the inner glass bottle fail. After implementing these packaging procedures, Veolia has not had any incidents of leaking nitric acid initiating a fire, of fumes, or of leaking material breaching the outer packaging. James Scott commented that this packaging requirement would be a cost burden for companies that still pack nitric acid in glass and further noted that the addition of intermediate packagings and absorbent material may require current combination packagings to be modified. Mr. Scott suggested that this impact can be minimized if flexible intermediate packagings are allowed and that the word ‘‘rigid’’ should not appear as part of the requirement. 
PHMSA received only positive 
comments on this proposal. As proposed in the NPRM, the revised § 173.158(e) requires that when placed in wooden or fiberboard outer packagings, the glass inner packagings 
must be packed in tightly-closed, non- reactive intermediate packagings, cushioned with a non-reactive absorbent 
material. The use of a flexible intermediate packaging is authorized, provided it can be tightly-closed and is non-reactive to the nitric acid. A ‘‘rigid’’ intermediate packaging was not proposed. Therefore, in this final rule, PHMSA is adopting the revision to § 173.158(e) as proposed in the January 23, 2015 NPRM. PHMSA notes that we did not receive any comments in response to the NPRM solicitation asking that proposed packaging be applied to any other specific hazardous materials and therefore, we are limiting the revision to nitric acid as proposed. 
Pressure Test and Internal Visual 
Inspection Requirements for MC 331 Cargo Tanks (P–1604) 
The NPGA submitted a petition 
(P–1604) requesting that PHMSA modify the pressure test and visual inspection test requirements applicable to certain MC 331 specification cargo tanks in dedicated propane delivery service, commonly known as bobtails, found in § 180.407(c). Currently, the HMR requires periodic pressure testing and visual inspection every five years to remain in service; however, the NPGA petitions PHMSA to extend the requalification period for certain MC 331 cargo tanks from five years to ten years and provides a technical case for this change. 
The NPGA states in its petition that 
the five-year requalification period for bobtails is a burden to the propane industry further stating that these cargo tanks must be taken out of service for a period of up to a week and that water is introduced into the tank during the requalification process, which can be detrimental to both the tank and the contents. Before a tank can be returned to service, it must be completely free of any water. The NPGA states that this removal from service hinders a propane 
company’s operations. 
In 2001, the NPGA conducted a 
survey to determine whether companies that performed the five-year hydrostatic test requirement had experienced any failures. None of the 203 survey respondents reported a hydrostatic test failure for tanks of less than 3,500 gallons water capacity. Based on the results of this survey, the NPGA sponsored a study by the Battelle Memorial Institute (Battelle), a non- profit research and development organization, to determine whether a change to the requalification period would be technically feasible. Battelle developed crack growth models to estimate the time to failure of a tank that has undergone several pressure cycles. They also analyzed effects on the MC

service load conditions to determine the estimated life of the tank. 
Based on the results of this study, the 
NPGA and Battelle recommend that PHMSA modify the requalification period from five years to ten years for MC 331 cargo tanks that: (1) Are used in dedicated propane service; (2) have a water capacity less than 3,500 gallons; and (3) are constructed of non-quenched and tempered (NQT) SA–612 steel and NQT SA–202 or SA–455 steels, provided the materials have full-size equivalent (FSE) Charpy Vee notch energy test data that demonstrates 75 percent shear-area ductility at 32 °F 
with an average of three (3) or more samples greater than 15 ft-lb FSE, and none with less than 10 ft-lb FSE. A copy of this study is in the docket for this rulemaking. 
After considering the NPGA survey 
results, which cite no reported incidents, and the study commissioned by the NPGA, PHMSA determined that the petition merited consideration of a rulemaking change. The NPGA notes there is a strong safety record amongst its members regarding this issue and the cost savings to the industry would be significant. The NPGA commented in support of the proposed revision to the requalification requirements for MC 331 or bobtail cargo tanks and provided cost estimates as requested by PHMSA. They provide that requalification pressure tests can cost as much as $3,000 when factoring in the downtime of the bobtail as well as the labor and fuel required to drive it to the testing shop or facility. In addition, the NPGA estimates that there are approximately 18,000 bobtails in service that would be eligible for the extension to the requalification period. This represents a total industry cost of about $54 million to requalify these vehicles by hydrostatic test. If the proposed requirements are extended to ten years, it would reduce the industry’s costs by half, resulting in approximately $5.4 million on an annual basis. 
PHMSA received one anonymous 
comment concerning the provisions in Note 5 to the § 180.407(c) table. In addition to MC 331 cargo tanks constructed of nonquenched and tempered NQT SA–612 steel, Note 5 authorizes a ten-year inspection interval period applicable to cargo tanks 
constructed of NQT SA–202 or NQT SA–455 steel. This ten year interval applies if the materials have full-size equivalent (FSE) Charpy vee notch (CVN) energy test data that demonstrated 75 percent shear-area ductility at 32 °F with an average of 
three (3) or more samples greater than 15 ft-lb FSE with no sample less than 10 ft-lb FSE. The commenter states that 
Note 5 contains very specific information that is not available to most cargo tank owners or enforcement personnel. As such, the commenter states that there will be no way to determine that the cargo tank satisfies the Note 5 requirements on the roadside or at the cargo tanks owner’s place of business without the paperwork to verify compliance. The commenter also states that PHMSA needs to make clear that if a cargo tank owner cannot document this information, then the cargo tank is not eligible for the ten-year requalification period and would be subject to a five-year requalification interval. 
PHMSA agrees that if a cargo tank 
owner cannot produce documentation that a MC 331 cargo tank meets the requirements for a ten-year requalification interval, they are subject to the five-year requalification interval. Section 178.337–2(a)(3) requires that a MC 331 fabricator shall record the heat, and slab numbers, as well as the certified Charpy impact values where required, of each plate used in each cargo tank on a sketch showing the location of each plate in the shell and heads of the cargo tank. Copies of each sketch shall be provided to the owner, retained for at least five years by the fabricator, and made available to duly identified representatives of the Department of Transportation. PHMSA received no other comments on this issue and therefore, we are adopting as proposed to revise the pressure test and internal visual inspection requirements found in § 180.407(c) for certain MC 331 specification cargo tanks from a five- year requalification period to a ten-year period. 
Mobile Acetylene Trailer Systems 
(P–1605) and NTSB Safety 
Recommendations H–09–01 and H–09–02 
The CGA submitted a petition (P– 
1605) requesting that PHMSA amend the HMR to incorporate a reference to CGA G–1.6–2011, Standard for Mobile Acetylene Trailer Systems, Seventh Edition, copyright 2011. This standard provides minimum requirements necessary for the design, construction, and operation of mobile acetylene trailer systems, which consist of acetylene cylinders mounted and manifolded for the purposes of charging, transporting, and discharging acetylene. It also covers ground-mounted auxiliary equipment used with mobile acetylene trailers such as piping, meters, regulators, flash arrestors, and fire protection equipment. 
This petition coincides with two 
NTSB recommendations (H–09–01 and H–09–02) issued to PHMSA based on incidents involving mobile acetylene trailers.
1In response to the petition and 
recommendations, PHMSA determined that it would consider a rulemaking change. Further detailed discussion of this issue can be found in the Section- by-Section Review for § 173.301. 
Pressure Relief Devices for Cargo Tanks 
(P–1609) 
The TTMA submitted a petition 
(P–1609) requesting that PHMSA amend the requirements of § 180.407 applicable to pressure relief devices (PRDs). Specifically, TTMA requests that PHMSA revise the HMR to more clearly establish the set pressure of a PRD for each of the DOT specification cargo tank motor vehicles. The TTMA states that the wording of § 180.407(d)(3) and (g)(1)(ii), applicable to the testing requirements for PRDs, creates issues for persons performing the testing. 
The TTMA points out two specific 
issues with these paragraphs: The first is the term ‘‘set-to-discharge.’’ On April 9, 2009, PHMSA published a final rule [Docket No. PHMSA–2006–25910 (HM– 218E); 74 FR 16135; effective May 11, 2009], where in an attempt to harmonize with international standards, PHMSA replaced the phrase ‘‘set-to-discharge’’ with ‘‘start-to-discharge.’’ The TTMA explains that this is an issue because the discharge pressure referenced is used to figure the minimum pressure at which the PRD should reseat. By changing the wording from ‘‘set’’ to ‘‘start,’’ the reseating pressure changed from a design requirement to one based on what a given vent actually does under test. Therefore, instead of testing a PRD knowing its reseating requirements, testers must perform the test of a given PRD, calculate the reseating pressure of that particular PRD, and then, retest from that pressure. Essentially, testers of PRDs could test identical products at different pressures because the reseat pressure is no longer a fixed design requirement. This creates inconsistencies between the reseating pressures of comparable PRDs authorized for identical hazardous materials service. The TTMA states that this change compromises safety, instead of promoting it. 
The second issue TTMA points out in 
its petition is in regards to the term ‘‘the required set pressure.’’ This term is problematic in relation to the continuing operation of existing cargo tanks made to older specifications in § 180.405(c). As the codes for the older 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00008 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335491 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
specifications of cargo tanks are no 
longer published, determining ‘‘the required set pressure’’ is problematic. This is an issue for current specifications of cargo tanks as well. There are pressure allowances during the retesting of pressure relief devices of no more than 110 percent of the required set pressure (§ 180.407(d)(3)) and the same 10 percent allowance for DOT–400 series cargo tanks (§ 178.345– 10(d)) creates confusion for current specification cargo tanks. The TTMA believes this will create an unsafe condition for tanks, as a PRD is no longer functioning as designed by the manufacturer; thus the PRD may actually open at higher pressures (near a cargo tank’s test pressure) as opposed to the appropriate lower design pressure. 
The TTMA petitioned that PHMSA 
revise the HMR for testing of PRDs by replacing the current requirements found in § 180.407(d)(3) and (g)(1)(ii) with a reference to a new paragraph (j) that would detail the PRD test requirements. The TTMA believes this change will eliminate confusion for testers by clarifying the requirements for opening and reseating pressures when beginning the tests, while simultaneously enhancing the enforcement of these requirements by creating consistency in the testing requirements for cargo tank PRDs of the same design. 
PHMSA determined that TTMA’s 
petition merited consideration of a rulemaking change based on the need for consistent and clear testing requirements for PRDs on DOT specification cargo tanks, and as a result, PHMSA received five comments in support of the proposed revision. Girard Equipment, Inc., TTMA, Mr. Peter Weis, Betts Industries Inc., and Dow Chemical Company commented in support of the amendment. One anonymous commenter believed the proposed amendment is not in the best interest of safety, stating that the revision will allow for PRDs intended for the DOT–400 series of cargo tanks to be installed on DOT–300 series cargo tanks, therefore opening at well over the maximum allowable working pressure (MAWP) of the DOT–300 series. The TTMA responded to this commenter in a follow-up comment stating that the anonymous commenter is incorrect, further stating that the proposed amendment keeps PRDs on upgraded DOT–300 series cargo tanks functioning according to the requirements for DOT– 400 series cargo tanks and that this represents an improvement in safety, 
which is why they are required on current construction and why provision is made for upgrading older 
construction tanks. Due to the overwhelming support to TTMA’s petition and the NPRM, PHMSA is adopting the revisions to both § 180.407(d)(3) and (g)(1) as proposed to reference a new paragraph (j), which will outline the testing requirements applicable to PRDs. 
Application for Designation as a 
Certification Agency 
An anonymous commenter stated that 
§ 107.402(f) incorrectly cites the requirements for inspection and test marking in § 180.605(k) and further suggests that § 107.402(f) should cite the pressure test procedures in § 180.605(h). PHMSA disagrees, believing instead that § 107.402(f) should be revised to correctly reference Approval of Specification UN Portable Tanks, which would be consistent with § 107.402(f)(2). Therefore, in this final 
rule, PHMSA will revise § 107.402(f) to reference § 178.273 instead of § 180.605(k). 
B. Provisions Not Adopted in This Final 
Rule 
Based on an assessment of the 
proposed changes and the comments received, PHMSA identified four provisions that we are not adopting in this final rule: (1) The incorporation by reference into § 171.7 of the proposed edition of the Association of American Railroads (AAR) Manual of Standards and Recommended Practices, Section C–III, Specifications for Tank Cars, Specification M–1002 (Specifications for Tank Cars); (2) the revision to the forbidden material requirements in § 173.21(e); (3) the odorization of cylinders and certain cargo tanks containing liquefied petroleum gas (LPG); and (4) the revision to the definition of ‘‘person’’ in § 180.401. Below is a summary of the amendments proposed, the comments received, and PHMSA’s rationale for not adopting these proposed amendments. 
Incorporation by Reference of AAR 
Specifications for Tank Cars (M–1002) 
The National Technology Transfer 
and Advancement Act of 1995 (15 U.S.C. 272) directs agencies to use voluntary consensus standards in lieu of government-unique standards except where inconsistent with law or otherwise impractical. Section 171.7 lists all standards incorporated by reference into the HMR and informational materials not requiring incorporation by reference. One particular incorporation by reference is the AAR’s Specifications for Tank Cars, 
October 2000 edition for various tank car design, manufacture, inspection and 
testing, and qualification regulations set forth in parts 173, 179, and 180 of the HMR. As currently incorporated by reference, all sections refer to the October 2000 edition of this document. 
AAR frequently updates the 
specifications for tank cars; however, PHMSA has not formally received a petition for rulemaking to revise the HMR to reflect more current versions of the AAR Specifications for Tank Cars. 
In the NPRM, we proposed to revise 
the incorporation by reference for this document to include the 2007 edition of the AAR Specifications for Tank Cars and certain subsequent amendments. PHMSA also proposed to revise § 179.24(a)(2) to remove the reference to the December 2000 edition of this document and instead replace it with a generic reference to the AAR Specifications for Tank Cars. Additionally, we proposed to revise § 180.503 to replace the reference to the ‘‘AAR Tank Car Manual’’ with ‘‘AAR Specifications for Tank Cars’’ for consistency with references to this document elsewhere in the HMR. PHMSA also notes that the FRA had reviewed the 2007 standard and the subsequent amendments and determined not to incorporate the 2007 standard in its totality. 
PHMSA received three negative 
comments to this direct proposal for incorporation by reference. The Chlorine Institute (CI) commented that it is PHMSA’s assertion that FRA does not support certain amendments of a given chapter or appendix [of the Specifications for Tank Cars] due to ‘‘safety concerns,’’ furthermore stating that those concerns should be explained in the rulemaking. If FRA has determined that specific standards or practices are unsafe, CI questions if it should be required to comply with a different version of the M-1002 Tank Car Manual, per AAR requirements, as opposed to simply complying with what is currently in the HMR. The AAR requests that the final rule include the latest edition of the AAR Specification for Tank Cars that was published in November 2014 and that PHMSA provide it with a list of these ‘‘safety concerns’’ in reference to the AAR Specifications for Tank Cars. Moving forward AAR strongly supports working 
together with PHMSA and FRA on a scheduled implementation plan to evaluate and incorporate amendments made by the AAR to the incorporation by reference of the AAR Specifications for Tank Cars. Dow Chemical Company had concerns with PHMSA’s approach and believes the HMR should simply incorporate by reference the most

current version of the AAR 
Specifications for Tank Cars. They go on to state that referencing certain previous amendments of older versions of the standards into the HMR will cause confusion and unnecessary burden. If, as PHMSA states in the NPRM, the FRA does not support specific current AAR standards or practices and deems them unsafe, then Dow Chemical Company believes those ‘‘safety concerns’’ should further be explained. 
After consideration of the comments 
received, PHMSA in consultation with FRA agrees with commenters and will not adopt the incorporation by reference as proposed. PHMSA and FRA agree that the safety concerns raised by FRA are not adequately explained and that a more current version of the AAR Specifications for Tank Cars is available and thus good cause reasons exist for not adopting the proposed amendment. The FRA will continue to evaluate amendments made to the AAR Specifications for Tank Cars and will update the effective dates for referenced chapters or appendices, as appropriate, when such amendments are supported by FRA. PHMSA and FRA agree with AAR that future collaborative efforts to update both the AAR Specifications for Tank Cars and the corresponding incorporation by reference into the HMR would be beneficial to stakeholders. 
PHMSA further notes that we 
received a negative joint comment from PublicResource.org and Greenpeace regarding our general practice of incorporating by reference. They did not comment on the substantive merits of the proposed rule. Instead, they ask PHMSA to recognize that it has acted illegally and arbitrarily at the NPRM stage in not making the standards— which are integral parts of the rule— available to the public for review without having to pay for them. They go on to state that the unwarranted action by PHMSA places an unreasonable burden on members of the public who wish to review the entire rule in order to fully understand it and to make appropriate comments. PHMSA disagrees with the basis for the joint comment as we have complied with the requirements in 1 CFR part 51 for incorporation by reference. However, as discussed above, we are not adopting the revision to the incorporation by reference of the AAR Specifications for Tank Cars as proposed. 
It is noted that the editorial revisions 
to §§ 179.24(a)(2) and 180.503 are being adopted as proposed as clarifying amendments. Prohibition of Materials in the Same 
Transport Vehicle 
Section 173.21 outlines forbidden 
materials and packages, with paragraph (e) of this section forbidding the transport of a material in the same packaging, freight container, or overpack with another material, that if mixed would likely cause a dangerous evolution of heat, flammable or poisonous gases or vapors, or the production of corrosive materials. While this prohibition prevents incidents from occurring within a freight container, overpack, or the same container, there is no prohibition on this type within a transport vehicle (e.g., a truck with 
single trailer). 
In May 2013, PHMSA received a 
request for a letter of interpretation (Ref. No. 13–0111) describing a potentially dangerous situation whereby a company offers for transportation ‘‘UN1908, Chlorite Solution, Class 8, Packing Group (PG) II,’’ ‘‘UN1791, Hypochlorite Solutions, Class 8, PG III’’ and ‘‘UN1789, Hydrochloric Acid Solution, Class 8, PG II’’ in separate intermediate bulk containers (IBCs) in the same transport vehicle. While there are no formal segregation requirements per § 177.848 of the HMR, data accompanying the letter indicated that in the event of co-mingling, these materials would create chlorine dioxide gas. ‘‘Chlorine dioxide (not hydrate)’’ is forbidden for transportation per the § 172.101 HMT. Thus, the transportation of these materials in the same transport vehicle would create a situation where the mixing of the materials would produce a poisonous gas and highly corrosive material, which happens to also be forbidden from transport; yet, under the current construct of § 173.21, there is no prohibition against this transport scenario. 
In the NPRM, PHMSA proposed to 
prohibit the transportation or offering for transportation of materials in the same transport vehicle (e.g., a trailer, a 
rail car) with another material that is likely to cause a dangerous evolution of heat, flammable or poisonous gases or vapors, or produce corrosive materials upon mixing for both rail and highway transport. 
PHMSA received 13 comments on the 
proposed amendment from AAR, ACC, ATA, CI, COSTHA, DGAC, IME, Jones Chemical, NACD, RIPA, UPS, USWAG, and Veolia. All of the comments strongly opposed the proposed amendment. The commenters addressed topics related to the proposed amendment such as the difficulty in implementing the prohibition; the impact on shipper and carrier operations; the economic implications; 
and the safety benefit, or lack thereof. An overview of these comments is provided below, and the complete list of comments pertaining to this amendment is available in the docket for this rulemaking. 
The majority of commenters stated 
that carriers, offerors, and other hazardous materials employees typically have neither sufficient information available nor the technical expertise to make the assessments necessary to comply with the proposed amendment. As such, a carrier cannot be expected to identify and evaluate each individual package consigned for carriage to determine whether the materials in those packages would be compatible with each other in the unlikely event they were to be unintentionally mixed. Further, shippers cannot possibly know what other packaged materials will be transported in the vehicle carrying their products and cannot be expected to determine whether any of the materials onboard the vehicle, if inadvertently mixed, would create a hazard. The DGAC commented that this prohibition would apply not only to materials identified as hazardous materials, but also to non-hazardous materials. 
The majority of commenters stated 
that the proposed prohibitions would result in increased costs as offerors and carriers would need to further segregate hazardous materials, thus creating the need for separate trucks to carry materials presently authorized for carriage in a single truck. Several of the commenters indicated that this would increase highway traffic as well as the probability of highway accidents. Veolia commented that many of their customers generate waste materials that would be deemed to be incompatible for shipment together if this new restriction is adopted further stating that this would result in the need to ship the wastes off-site for disposal using more than one transport vehicle to accommodate the proposed restrictions. Another commenter, NACD, notes there would be an increase in distributor costs, as distributors would need to purchase more trucks to increase their fleets. 
Several commenters stated their belief 
that the segregation provisions of 
§ 177.848 already sufficiently address the danger associated with co-loading incompatible materials and that these provisions have a proven and long- standing safety record. COSTHA commented that the § 177.848 segregation table clearly indicates when certain hazard classes or divisions are known to react dangerously and,

therefore, when they must be 
segregated. COSTHA further noted that the segregation table was developed on the basis that the current classification system is an adequate and appropriate manner to classify materials. Furthermore, Veolia pointed out PHMSA’s own words in letter Ref. No. 13–0111: ‘‘[w]e recognize the concerns that you have regarding the transport of Chlorite and Hypochlorite Solutions with Hydrochloric Acid in the same transport vehicle. However, we believe that the packaging requirements for these materials mitigate the potential for comingling and subsequent dangerous evolution of gas.’’ 
Based on the comments received, 
PHMSA will not be adopting any changes to the forbidden materials provisions specified in § 173.21(e). It was not PHMSA’s intent to propose an amendment that would impose a significant operational and economic burden on the regulated community; rather PHMSA’s intention was to address a safety issue identified through a request for a letter of interpretation. Based on further review and the rationale presented by commenters, PHMSA believes the current packaging and segregation requirements adequately address the unlikely scenario of a dangerous situation caused by the unintentional and unlikely mixing of materials during transport. 
Odorization of Cylinders and Certain 
Cargo Tanks Containing Liquefied Petroleum Gas (LPG) 
Section 172.304a prescribes the filling 
requirements for cylinders containing compressed gases. In the NPRM, PHMSA proposed to add new § 173.304a(d)(5) in addition to the proposed revised text in §§ 173.314(h) and 173.315(b)(1) that addresses the odorization of LPG in rail tank car tanks and cargo tanks, respectively. We also proposed to revise the existing § 173.315(b)(1) to add a performance standard to address the issues of ‘‘under-odorization’’ and ‘‘odor fade.’’ PHMSA received comments from the NPGA in opposition to extending the odorization standards proposed to cylinders and revision of the requirement to cargo tanks. They state that, while it may seem intuitive to simply apply the requirements to these additional containers, PHMSA was unaware of the impact this will have on retail propane marketers further downstream in the distribution chain, and as proposed, they believe the requirement would place an undue burden on retail propane marketers, particularly for the more than 90 percent of NPGA members designated as 
small businesses. 
On June 26, 2015, PHMSA met with 
representatives of NPGA and their membership, as well as the National Association of State Fire Marshalls (NASFM) to discuss the odorization provisions in the NPRM. In this meeting, NPGA and NASFM outlined in further detail their concerns with the proposed requirements. The NPGA reiterated the downstream consequences of the proposed requirement to fillers, distributors, and sellers of cylinders and smaller cargo tanks under 3,500 gallons capacity (previously mentioned as ‘‘bobtails’’). As stated in their comment, NPGA provides cost information associated with the proposed requirements, estimating that with 200,000 cylinder fillings daily, quantitative testing requirements for cylinders would likely exceed $480 million per year to the industry. Bobtails that experience high turnover (three to five fills per day) would be subject to the proposed odorant performance standard as well. These distributors of propane do not have the odorant chemical (ethyl mercaptan) on site, nor the trained personnel and experience to comply with the proposed requirement. They went on to state that applying the requirement to rail tank cars is the most effective means of addressing odorant fade as it is the furthest upstream transportation. If a rail tank car is effectively odorized, all movement downstream would meet the odorant requirements and presumably not fade. The NASFM commented in the meeting in support of NPGA on this issue. Furthermore, the NPGA claimed that odorant fade is most likely to occur in mixed-use rail tank cars as they are not used in ‘‘dedicated service’’ and are cleaned prior to filling with propane. Meanwhile, bobtails and bulk storage tanks are in ‘‘dedicated service’’ so they experience less odorant fade due to being ‘‘seasoned’’—i.e., there is less 
absorption of odorant into the tank walls and, thus, more odorant remains mixed with the LPG. 
In the meeting, the NPGA stated that 
the National Fire Protection Association (NFPA) already requires a ‘‘sniff-test’’ for odorized LPG and provided cost information on the existing ‘‘sniff test.’’ 
While this test is not in the HMR, the cost data provided by NPGA estimates an annual total of $9 million to the industry. The NPGA cost information, as well as the meeting notes can be found in the docket for this rulemaking. 
PHMSA recognizes the NPGA’s 
concerns and does not intend to place an undue economic burden on retail distributors of LPG. With an understanding of the propane industry’s 
supply chain, we hope to address odorization further up the transportation stream to avoid odorant fade or under-odorization occurring downstream. It is not our intent to require retail distributors offering for transport or transporting propane from their bulk storage facilities to end users in cylinders or bobtail cargo tanks to qualitatively test odorant levels in the LPG. Instead, our goal with the revisions adopted would be to require this testing for larger packages of LPG (rail tank cars or certain cargo tanks) from a refinery, gas plant, or pipeline terminal destined for those retail distributors. While provisions requiring odorization and measures to address odorant fade or under-odorization for cylinders, cargo tanks, or portable tanks not originating from a refinery, gas plant, or pipeline terminal are not being adopted in this rule, amendments addressing rail tank cars and other point-of-origin transportation are discussed further in the preamble. 
Applicability of the Word ‘‘person’’ 
§ 180.401 
In the NPRM, PHMSA proposed to 
revise the term ‘‘person’’ to ‘‘hazardous materials employee or hazardous materials employer.’’ The proposed revision was an attempt to clarify that subpart E of part 180 qualification and maintenance of cargo tank requirements applies not only to persons offering hazardous materials for transportation or transporting a hazardous material, but also to those involved with qualification, maintenance, or periodic testing of cargo tanks. PHMSA received an anonymous comment pointing out 
that the proposed revision is unnecessary because the definition for ‘‘person’’ in § 171.8 already applies to a person that designs, manufactures, fabricates, inspects, marks, maintains, reconditions, repairs, or tests a package, container, or packaging component that is represented, marked, certified, or sold as qualified for use in transporting hazardous material in commerce. We agree with the commenter that the definition for ‘‘person’’ in § 171.8 already adequately and accurately addresses the applicability of subpart E of part 180. Therefore, PHMSA will not be adopting the proposed revision to § 180.401. 
Reference to the Manufacturer’s Report 
Requirements in § 178.65(i)(1) 
In the NPRM, we proposed to revise 
§ 178.65(i)(1) to correctly reference the manufacturer’s report requirements in § 178.35(g). A final rule published July 20, 2011 [Docket No. PHMSA–2009– 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00011 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335494 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
0151 (HM–218F)] removed paragraph 
(h) and moved the manufacturer’s report retention requirements into paragraph (g). Although PHMSA did not receive any comments on this proposed revision, PHMSA did identify a letter of interpretation (Ref No. 01–0125) that noted an error in what is referenced in § 178.65(i)(1). In the letter, PHMSA agreed that § 178.65(i)(1) should include an exception from the marking requirements provided in § 178.35(f), not the manufacturer’s report requirements in paragraph (h) (and subsequently paragraph (g)), and noted that it warranted a rulemaking change. In light of the letter of interpretation, PHMSA believes that further review is needed to determine the full intent of the exception provided in § 178.65(i)(1). Thus, PHMSA will not be adopting the revision to § 178.65(i)(1) as proposed. 
C. Comments Outside the Scope of This 
Rulemaking 
PHMSA received eighteen (18) 
comments that were either outside the scope of the proposed rulemaking or not specifically addressing the proposed regulatory changes. Mr. Adrian Mendoza generally supported PHMSA’s rulemaking efforts in the interest of public health and safety. Mr. Aaron Adamczyk submitted a list of materials to be incorporated by reference but did not respond directly to any provisions in the NPRM. An anonymous commenter stated that the issue that caused the revision proposed in §§ 173.170 and 173.171 is also found in § 173.6 for materials of trade, and the term ‘‘motor vehicle,’’ which includes both the truck and trailer, limits the exception; the commenter further requested that we consider changing the term ‘‘motor vehicle’’ to ‘‘transport vehicle’’ to allow the materials of trade exception to apply to each unit. While 
PHMSA finds value in this comment, we did not propose this revision and therefore will not adopt the commenter’s suggestion. 
Another anonymous commenter 
stated that the definitions of cargo tank in §§ 171.8 and 178.320 do not match and further requests revising the definition in § 171.8 to be consistent with the definition in § 178.320, which includes solids and semi-solids. This revision was also not proposed in the NPRM, and therefore, PHMSA is not adopting the change. 
The remaining fourteen (14) 
comments addressed our August 1, 2014, ‘‘Enhanced Tank Car Standards and Operational Controls for High- Hazard Flammable Trains (HM–251),’’ proposed rule. That rulemaking covered several key issues related to the safe transport of crude oil and other flammable liquids by rail and its comment period closed on September 30, 2014 under Docket No. PHMSA– 2012–0082. As these issues raised by commenters under the docket for HM– 218H were not proposed in HM–218H, PHMSA will not address the comments in this final rule and consider the comments as outside the scope of the rulemaking. 
IV. Section-by-Section Review 
Part 107 
Section 107.402 
Section 107.402 sets forth the 
application requirements for 
designation as a certification agency to issue certificates and certifications for packagings designed, manufactured, tested, or maintained in conformance with the HMR and standards set forth in the UN Model Regulations. This section also sets forth the application requirements for designation as a certification agency to issue certificates and certifications for lighters, portable tanks, multi-element gas containers, and Division 1.4G consumer fireworks. 
PHMSA is revising § 107.402(d)(1)(i) 
to indicate that a fireworks certification agency applicant must be a U.S. resident or, for a non-U.S. resident, must have a designated U.S. agent representative as specified in § 105.40. The criteria for fireworks certification agencies were added to the HMR in a final rule published April 2, 2015 [Docket No. PHMSA–2010–0320 (HM–257); 78 FR 42457]. PHMSA intended for § 107.402(d)(1)(i) to correspond with the requirements of § 105.40, which specifies designated agents for non- residents; however, the term ‘‘citizen’’ was inadvertently substituted for ‘‘resident,’’ thus PHMSA is revising § 107.402(d)(1)(i) by replacing the term ‘‘citizen’’ with the term ‘‘resident.’’ 
PHMSA is also revising § 107.402(e) 
to require that a lighter certification agency submit a statement to the Associate Administrator explaining that the agency is independent of and not owned by a lighter manufacturer, distributor, import or export company, or proprietorship. Further, we are revising § 107.402(f) to require that a portable tank and MEGC certification agency submit a statement to the Associate Administrator indicating that the agency is independent of and not owned by a portable tank or MEGC manufacturer, owner, or distributor. This language was included in § 107.402 and pertained to all certification agencies, but it was removed inadvertently as a result of changes made to the HMR in rulemaking HM– 257. 
Section 107.402(f) sets forth the 
requirements for portable tank and MEGC certification agencies prior to inspecting for compliance with the HMR. PHMSA is revising § 107.402(f) to reference Approval of Specification Portable Tanks as provided in § 178.273, rather than § 180.605(k). This would be consistent with § 107.402(f)(2). 
Section 107.807 
Section 107.807 sets forth the 
requirements for authorizing chemical 
analyses and tests for non-domestic manufacturers of DOT specification or special permit cylinders. To maintain consistency with requirements of other independent inspection agencies, PHMSA is revising § 107.807(b)(3) to require that the agency submit a statement indicating that the inspection agency is independent of and not owned by a cylinder manufacturer, owner, or distributor. 
Part 171 Section 171.7 
As previously stated, the National 
Technology Transfer and Advancement 
Act of 1995 (15 U.S.C. 272) directs agencies to use voluntary consensus standards in lieu of government-unique standards except where inconsistent with law or otherwise impractical. Section 171.7 lists all standards incorporated by reference into the HMR and informational materials not requiring incorporation by reference. The informational materials not requiring incorporation by reference are noted throughout the HMR and provide best practices and additional safety measures that, while not mandatory, may enhance safety and compliance. Table 1 in § 171.7 lists informational materials that are not incorporated by reference. In a final rule published on January 28, 2008 [Docket No. 2005– 21812 (HM–218D); 73 FR 4699, effective October 1, 2008], PHMSA added in Table 1 (formerly paragraph (b) of the section) an entry for the CGA publication, CGA C–1.1, Personnel Training and Certification Guidelines for Cylinder Requalification by the Volumetric Expansion Method. Following the publication of HM–218D, PHMSA received an appeal from Hydro- Test Products, Inc. (PHMSA–2005– 21812–0025) asking us to either remove the reference to CGA C–1.1 or add examples of other training materials that may be used. Hydro-Test noted that referencing only the CGA publication in the HMR could suggest that other training materials are not acceptable. 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00012 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335495 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
PHMSA added CGA C–1.1 as an 
example of guidance material that may be used to assist requalifiers in creating their cylinder training procedures and recordkeeping requirements. The publication is not a standalone tool for training persons on how to perform requalification of cylinders using the volumetric expansion test method. To alleviate confusion for cylinder requalifiers, PHMSA intended to remove the reference to CGA C–1.1 in §§ 171.7 and 180.205 in a previous editorial final rule published on October 1, 2008 [Docket No. PHMSA–2008–0227 (HM–244A); 73 FR 57001, effective October 1, 2008]. However, PHMSA removed reference to the document only in § 180.205(g)(6) and inadvertently failed to remove the reference in § 171.7. In this final rule, PHMSA is amending Table 1 to § 171.7 by removing the entry for CGA C–1.1 to align the regulatory text with previous rulemaking actions. 
Additionally, as described in the 
Comment Discussion for petition for rulemaking P–1605 and more fully discussed in the Section-by-Section Review for § 173.301, PHMSA is amending the HMR to incorporate by reference CGA G–1.6–2011, Standard for Mobile Acetylene Trailer Systems, Seventh Edition, copyright 2011. 
Section 171.7(k) incorporates The 
AAR Manual of Standards and Recommended Practices, Section C— Part III, Specifications for Tank Cars, Specification M–1002, (AAR Specifications for Tank Cars), December 2000. This standard prescribes approval 
requirements, general design and test requirements, structural requirements, valves and fittings, marking, recommended maintenance practice, and certification of tank car facilities. In this final rule, PHMSA is amending paragraph (k) of this section to list 
sections §§ 179.24 and 180.503 that reference this standard but were inadvertently omitted in a final rule published June 25, 2012 [Docket No. PHMSA–2010–0018 (HM–216B); 77 FR 37961]. 
Section 171.22 
In a May 3, 2007 final rule [Docket 
No. PHMSA–2005–23141 (HM–215F); 
72 FR 25162], the importer responsibility requirements were transitioned from § 171.12(a) to § 171.22(f). When transitioning the requirement that a person importing a hazardous material into the United States must provide the shipper and forwarding agent with information required under the HMR, the shipper notification was inadvertently omitted. As a result, only the forwarding agent is presently required to be provided with information as to the requirements of the HMR applicable to the particular shipment. In this final rule, PHMSA is reinstating text in § 171.22(f) to clearly state that both the shipper and forwarding agent at the place of entry must be provided with written information on the requirements of the HMR applicable to the particular shipment. PHMSA received two comments from ACA and DGAC providing general support for the amendment as proposed. 
Part 172 Section 172.101 
Section 172.101 contains the HMT 
and explanatory text for using the table 
information and each of the columns. In this final rule, PHMSA is making a number of revisions to the § 172.101 HMT: including the special provisions listed in Column (7) and specified in § 172.102; removing the PG II designation from Column (5) of the HMT for organic peroxides (Division 5.2), self-reactive substances (Division 4.1), and explosives (Class 1) as requested in P–1590; and clarifying the regulations and correct inadvertent errors. Changes to the § 172.101 HMT will appear as a ‘‘revise,’’ and include changes to the following table entries: ‘‘Calcium nitrate, UN1454,’’ ‘‘Corrosive liquids, flammable, n.o.s., UN2920,’’ ‘‘Fire extinguishers, UN1044,’’ ‘‘Oxidizing solid, corrosive, n.o.s., UN3085,’’ ‘‘Propellant solid, UN0501,’’ ‘‘Trinitrophenol (picric acid), wetted, with not less than 10 percent water by mass, UN3364,’’ and ‘‘Trinitrophenol, wetted with not less than 30 percent water, by mass, UN1344.’’ 
The entry for ‘‘Calcium nitrate, 
UN1454’’ is being revised to reflect a change that was intended to be made when PHMSA published a final rule on January 7, 2013 [Docket No. PHMSA– 2012–0027 (HM–215L); 78 FR 987]. Special Provision B120 was inadvertently not assigned to the entry for ‘‘Calcium nitrate, UN1454’’ when several other HMT entries were revised to include it. Special Provision B120 indicates that the material, when offered in conformance with the applicable requirements of part 178 and general packaging requirements in part 173, may be offered for transportation in a flexible bulk container. PHMSA is revising the HMT to add Special Provision B120 to Column (7) for the entry ‘‘Calcium nitrate, UN1454.’’ 
The entry for ‘‘Corrosive liquids, 
flammable, n.o.s., UN2920’’ is being revised to harmonize the HMR with the UN Model Regulations, IMDG Code, and the ICAO TI by means of providing limited quantity exceptions for the PG II 
entry. Therefore, PHMSA is revising the entry for ‘‘Corrosive liquids, flammable, n.o.s., UN2920, PG II’’ to remove the word ‘‘None’’ from Column (8A) of the HMT and add ‘‘154.’’ This change will be consistent with similar PG II materials that are also provided the limited quantity exception. 
The entry for ‘‘Fire extinguishers, 
UN1044’’ is being revised to eliminate reference to Special Provision 18, which is no longer in the HMR. Special Provision 18 was removed from § 172.102(c)(1) in a January 7, 2013 final rule [Docket No. PHMSA–2009–0126 (HM–215K); 78 FR 1101] and combined into revised § 173.309(a). We did not make a conforming amendment to remove Special Provision 18 from this entry in the HMT; thus, in this final rule, we are to revising the entry for ‘‘Fire extinguishers, UN1044’’ by deleting the special provision. 
The NPRM proposed to revise the 
entry for ‘‘Oxidizing solid, corrosive, n.o.s., UN3085’’ to harmonize with the UN Model Regulations, IMDG Code, and the ICAO TI by means of providing limited quantity exceptions for the PG II entry. However, in between the publishing of the NPRM and this final rule, PHMSA inadvertently revised this entry as proposed in a previous final rule [Docket No. PHMSA–2015–0103 (HM–260); 80 FR 72914]. Therefore, PHMSA will not be revising this entry in this final rule. 
PHMSA received four comments on 
the proposed revisions to the UN3085 (as well as UN2920) in Column (8A). In their comments, ACA, Veolia, and URS supported the revision of these two entries to harmonize with UN Model Regulations, IMDG Code, and the ICAO TI. The URS provided a list of nine (9) additional PG II entries for which a limited quantity exception is provided under international standards but not in the HMR and requested the same revision made to UN2920 and UN3085 be made to these additional entries. An anonymous commenter requested that PHMSA make the same limited quantity exception revision to the UN3084, PG II entry. PHMSA agrees with the commenters that the HMR is not completely in alignment with the with UN Model Regulations, IMDG Code, and the ICAO TI limited quantity exceptions 
with regard to these additional PG II entries. However, given the lack of historical context and the need for a technical review of each entry, PHMSA will only be revising the limited quantity exception for the entries that have been proposed. PHMSA may consider the revision to additional entries offered by the commenters under 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00013 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335496 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
a future rulemaking. Additionally, 
PHMSA encourages the commenters to submit a petition for rulemaking in accordance with §§ 106.95 and 106.100 for entries that they believe should also be revised. 
The entry for ‘‘Propellant, solid, 
UN0501’’ is being revised to eliminate a reference to a requirement that is no longer in the HMR. Column (10B) of this entry lists vessel stowage provision 24E; however, vessel stowage provision 24E was removed from § 176.84(c)(2) when the Research and Special Programs Administration (RSPA), PHMSA’s predecessor, published a final rule on June 21, 2001 [Docket No. RSPA–2000– 7702 (HM–215D); 66 FR 33316, effective October 1, 2001] that revised the table of provisions applicable to vessel transportation of Class 1 (explosive) materials. As this provision is no longer in the HMR, PHMSA is revising the entry for ‘‘Propellant, solid, UN0501’’ to remove vessel stowage provision 24E from Column (10B) of the HMT. 
The HMT entries for ‘‘Trinitrophenol 
(picric acid), wetted, with not less than 10 percent water by mass, UN3364’’ and ‘‘Trinitrophenol, wetted with not less than 30 percent water, by mass, UN1344’’ are being revised to harmonize the HMR with the UN Model Regulations, IMDG Code, and the ICAO TI. Presently, Special Provision 162 is applied to UN3364 (not less than 10 percent water) and Special Provision 23 is applied to UN1344 (not less than 30 percent water). Special Provision 162 outlines a provision for transport of the material as Division 4.1: The material must be packed such that at no time during transport will the percentage of diluent fall below the percentage that is stated in the shipping description. Special Provision 23 is similar in that it also outlines this provision but includes an additional condition that quantities of not more than 500 grams per package with not less than 10 percent water by mass may also be classed in Division 4.1, provided a negative test result is obtained when tested in accordance with test series 6(c) of the UN Manual of Tests and Criteria. 
The special provisions are assigned in 
the reverse manner to the trinitrophenol entries in the UN Model Regulations, IMDG Code, and the ICAO TI. Special Provision 23 is applied to UN3364 with 
the lower minimum diluent percent of water while the 500 gram limit per package for 10 percent diluent does not apply to UN1344 with the larger minimum diluent percentage of water (i.e., 30 percent). Thus the special 
provision was incorrectly assigned in the HMR. For the entry ‘‘Trinitrophenol (picric acid), wetted, with not less than 10 percent water by mass, UN3364,’’ we 
are replacing Special Provision 162 in Column (7) of the HMT with Special Provision 23. Conversely, for the entry ‘‘Trinitrophenol, wetted, with not less than 30 percent water, by mass, UN1344,’’ we are replacing Special Provision 23 from Column (7) of the HMT with Special Provision 162. 
PHMSA is revising Column (8C) of 
the HMT for ‘‘Asbestos, NA2212,’’ ‘‘Blue asbestos (Crocidolite) or Brown asbestos 
(amosite, mysorite), UN2212,’’ and ‘‘White asbestos (chrysotile, actinolite, anthophyllite, tremolite), UN2590,’’ to refer to packaging instructions in § 173.216, instead of § 173.240. 
In a final rule published on November 
23, 2015 [Docket No. PHMSA–2015– 0103 (HM–260); 80 FR 72913], PHMSA revised the HMT entry ‘‘NA1993, Combustible liquid, n.o.s.’’ by removing special provision T4. In a subsequent final rule published on December 21, 2015 [Docket No. PHMSA–2011–0345 (HM–233D); 80 FR 79423] the same entry was revised by adding Special Provision 148. In making the addition of Special Provision of 148, the previously removed Special Provision T4 was inadvertently reinstated. This final rule corrects that error by removing Special Provision T4 from the entry for NA1993. 
In a final rule published on January 
21, 2016 [Docket No. PHMSA–2013– 0042 (HM–233F); 81 FR 3635], PHMSA 
did the following: 
•Inadvertently revised the 
‘‘Corrosive liquids, n.o.s., UN1760’’ entry by assigning it the incorrect NA prefix and inserting Special Provision 386 to the Packing Group II and III entries. The HM–233F final rule should have revised the ‘‘Compounds, cleaning liquid, NA1760’’ entry by adding Special Provision 386 to the Packing Group II and III entries. This final rule corrects those errors by removing Special Provision 386 from the ‘‘Corrosive liquids’’ entry and adding them to the ‘‘Compounds, cleaning liquid’’ entry, and re-assigning the ‘‘Corrosive liquids’’ entry the correct prefix of UN. 
•Inadvertently revised Column (10B) 
of the ‘‘Coating solution (includes surface treatments or coatings used for industrial or other purposes such as vehicle undercoating, drum or barrel lining), UN1139’’ entry by removing the 
vessel stowage provision E and replacing with the letter B. Consequently, PHMSA is restoring the letter E in Column (10B) for this entry. 
•Inadvertently revised Column (8B) 
of the ‘‘Printing ink, flammable or 
Printing ink related material (including printing ink thinning or reducing compound), flammable, UN1210’’ entry by changing the packaging section for 
Packing Group I from § 173.173 to § 173.201. Consequently, PHMSA is restoring § 173.173 in Column (8B) for this entry. Further, in this final rule, PHMSA is correcting the roman and italicized text for this entry in Column 
(2) of the HMT. 
•Inadvertently revised Column (7) of 
‘‘Self-heating solid, organic, n.o.s., UN3088’’ by removing UN portable tank code T1 from the Packing Group III entry. Consequently, PHMSA is restoring the code to Column (7) of the HMT. 
•Inadvertently revised Column (10B) 
of the ‘‘Potassium, UN2257’’, ‘‘Sodium, UN1428’’, and ‘‘Water reactive solid, n.o.s., UN2813’’ entries by removing vessel stowage provisions 13 and 148. Consequently, PHMSA is restoring the codes to Column (10B) of the HMT for each entry. 
Section 172.102 
Section 172.102 outlines special 
provisions that are listed in Column (7) 
of the § 172.101 HMT. Special Provision 136 is listed for the entry ‘‘Dangerous Goods in Machinery or Dangerous 
Goods in Apparatus, UN3363.’’ PHMSA received a request for a letter of interpretation (Ref. No. 12–0037) that sought confirmation that a material classed as a Class 2 gas that has packaging exceptions listed in Column (8A) of the HMT may be described as ‘‘Dangerous Goods in Apparatus, UN3363.’’ The requestor pointed out that the provisions in Special Provision 136 are inconsistent: Special Provision 136 currently states that except when approved by the Associate Administrator, machinery or apparatus may only contain hazardous materials for which exceptions are referenced in Column (8) of the HMT and are provided in part 173, subpart D. Subpart D contains the definitions, classification, packing group assignments, and exceptions for hazardous materials other than Class 1 and Class 7. However, preparation, packaging, and exceptions for Class 2 gases are located in subpart G of part 173. This should be indicated in Special Provision 136 to eliminate confusion that gases prepared in accordance with subpart G of part 173 would not be eligible to be described as ‘‘Dangerous Goods in Apparatus, UN3363.’’ It was not PHMSA’s intention to exclude Class 2 gases from using this proper shipping name, therefore, PHMSA is revising Special Provision 136 in § 172.102 to include reference to part 173, subpart G.

2R–07–4: With the assistance of the Federal 
Railroad Administration, require that railroads 
immediately provide to emergency responders accurate, real-time information regarding the identity and location of all hazardous materials on a train. Section 172.201 
Section 172.201 prescribes the 
requirements for the preparation and 
retention of shipping papers. This paragraph requires that, except as provided in § 172.604(c), a shipping paper must contain an emergency response telephone number. The reference in this paragraph to § 172.604(c) is inaccurate. The requirements in § 172.604 applicable to emergency response telephone numbers were changed when PHMSA published a final rule on October 19, 2009 [Docket No. PHMSA–2006–26322 (HM–206F); 74 FR 53413, effective November 18, 2009]. This rulemaking action moved the exceptions regarding the requirement to provide an emergency response telephone number to a new paragraph (d). PHMSA received one comment from the American Coatings Association (ACA) in support of this change without further issue. In this final rule, PHMSA is revising § 172.201(d) to accurately reference the exception from the emergency response telephone number requirement found in § 172.604(d). 
Sections 172.301, 172.326, 172.328, and 
172.330 
Sections 172.301, 172.326, 172.328, 
and 172.330 prescribe marking requirements for non-bulk packagings, portable tanks, cargo tanks, tank cars, and multi-unit tank car tanks, respectively. Each of these sections contains a paragraph (specifically, §§ 172.301(f), 172.326(d), 172.328(e), and 172.330(c)) prescribing requirements for packages containing unodorized LPG to be legibly marked with ‘‘NON-ODORIZED’’ or ‘‘NOT- ODORIZED.’’ PHMSA received a request for a letter of interpretation (Ref. No. 06–0235) requesting clarification that the ‘‘NON-ODORIZED’’ or ‘‘NOT- ODORIZED’’ mark may also appear on a package containing odorized LPG. In the response letter, we noted that PHMSA addressed this issue in part in a final rule published by its predecessor agency, RSPA, on November 4, 2004 [RSPA–03–15327 (HM–206B); 69 FR 64462, effective October 1, 2006]. Final rule HM–206B changed the hazard communication requirements applicable to certain packages containing unodorized LPG, including the requirement to mark with ‘‘NON- ODORIZED’’ or ‘‘NOT-ODORIZED.’’ Specifically, it also clarified that the ‘‘NON-ODORIZED’’ or ‘‘NOT- ODORIZED’’ marking may appear on a tank car or multi-unit tank car tanks used for both unodorized and odorized LPG. This was implemented to address the concerns expressed by a commenter 
about the logistics of tracking, inspecting, and stenciling tank cars to ensure proper marking. However, this clarification was not extended to cylinders, cargo tanks, and portable tanks containing LPG in that final rule. We further noted in the response letter that we intended to revisit this issue in a future rulemaking to extend this clarification to other packaging types that are filled with unodorized or odorized LPG. 
PHMSA received negative comments 
from the NASFM, the NTSB, the IAFC, and the New Hampshire Office of the State Fire Marshall. The NTSB disagrees with the proposed exception, citing a 2005 railroad incident involving the release of diesel fuel from a locomotive and Safety Recommendation R–07–4 as grounds for their dissent.
2The NTSB 
disagrees with both the proposed exception to expand eligible packaging types and the existing exception for tanks cars, stating that it is concerned that the ‘‘NON-ODORIZED’’ or ‘‘NOT- ODORIZED’’ package markings would be rendered meaningless by the proposal to allow such a marking on a tank containing odorized LPG. It believes it is poor policy to allow ‘‘mislabeling’’ of LPG tanks merely for logistical convenience, further stating that while the HMR does not require odorization in all cases, the requirement to properly mark these packages as ‘‘ODORIZED’’ or ‘‘NOT-ODORIZED’’ based on the actual condition of the LPG being transported (odorized or not odorized) should be a fundamental tenet to emergency response planning and execution involving hazardous materials in transportation. Therefore, the NTSB urged PHMSA not to approve the proposed rule changes and suggests that instead, PHMSA approve an acceptable means for the ‘‘NON-ODORIZED’’ or ‘‘NOT-ODORIZED’’ marking to be temporarily covered whenever the container is used to transport odorized LPG. PHMSA disagrees with this comment and is puzzled as to how the incident cited in NTSB’s comment, which involved a collision of two trains and a release of diesel fuel from locomotives, is relevant to the proposed language from the NPRM. The allowance for the marking to remain on a package already exists for tank cars, so PHMSA simply proposed to extend this exception to other packaging types. We also disagree that the marking would be rendered meaningless if allowed to remain on odorized tanks of LPG. If the contents were to undergo odorant fade during the course of transportation, this marking would provide an additional level of safety. Additionally, we fail to see how extending the requirement to existing package types is a detriment to the safety benefit provided by that mark existing on non-odorized packages of LPG. 
The NASFM, IAFC, and the New 
Hampshire Office of the State Fire Marshall also provided negative comment; however, they did not comment on the proposed exception, instead focusing on the existing regulatory allowance for the marking to remain on tank cars and multi-unit tank car tanks. The three commenters all stated that the allowance of the marking to remain on odorized packages will create confusion for first responders when looking for leaks from containers with odorized LPG. They state that if the mark is seen on a tank that is actually odorized, they will skip over that tank and may miss a leak. PHMSA disagrees with the commenters and while we fully appreciate the benefit that odorization has for leak detection in an emergency response situation, we do not feel that it is the sole method to detect such leaks. 
Thus, PHMSA is revising 
§§ 172.301(f), 172.326(d) and 172.328(e) to include the clarification that the marking may appear on these packagings used for both unodorized 
and odorized LPG and to remove the effective date of October 1, 2006. PHMSA is also removing the effective date referenced in paragraph § 172.330(c) for consistency. 
Section 172.406 
Section 172.406 specifies the 
placement of labels on a package. 
Paragraph (d) of this section prescribes requirements that labels be printed or affixed to a background of contrasting color, or they must have a dotted or solid line outer border. Further, § 172.407(b)(2) provides that the dotted line border on each label shown in §§ 172.411 through 172.448 is not part of the label specification, except when used as an alternative for the solid line outer border to meet the requirements of § 172.406(d). Based on this language, it appears that labels with a dotted or solid line outer border are permitted only if the surface of the package is not a contrasting color, thus causing confusion. 
In this rulemaking, we are amending 
§ 172.406(d) by expressly authorizing the use of labels described in part 172, subpart E with a dotted or solid line

outer border on a background of 
contrasting color. There is no reduction in hazard communication with this revision, and it will provide cost savings to shippers by eliminating the need to acquire and store two types of labels (one with a border and the other without) depending on the surface color of the package. PHMSA received one comment from ACA providing support for this amendment as proposed. 
Section 172.407 
Section 172.407 contains label 
specifications. Paragraph (d) of this 
section contains color specifications for labels including a requirement for color tolerances according to color charts referenced in appendix A to part 172 of the HMR. Paragraph (d)(4)(ii) states that the color charts are on display at the Office of Hazardous Materials Safety, Office of Hazardous Materials Standards, Room 8422, Nassif Building, 400 Seventh Street SW., Washington, DC 20590–0001. This address does not reflect the current address of the Office; thus PHMSA is amending the address in § 172.407(d)(4)(ii) to read Standards and Rulemaking Division, Pipeline and Hazardous Materials Safety Administration, U.S. Department of Transportation, 2nd Floor, East Building, 1200 New Jersey Avenue SE., Washington, DC 20590–0001. 
Section 172.514 
Section 172.514 prescribes the 
placarding requirements and exceptions 
for a bulk packaging containing a hazardous material. Paragraph (c)(4) provides an exception for an IBC that is labeled in accordance with part 172, subpart E, instead of placarded. IBCs that are labeled instead of placarded are authorized to display the proper shipping name and UN identification 
number in accordance with the bulk package marking size requirements of § 172.302(b)(2) in place of the UN number on an orange panel, placard, or white square-on-point. Section 172.302(b)(2) requires that for IBCs, markings have a width of at least 4.0 mm (0.16 inch) and a height of at least 25 mm (one inch). This is inconsistent with the UN Model Regulations, IMDG Code, and ICAO TI, which all require a height of 12 mm (0.47 inch). The international size requirement is equivalent to the non-bulk marking size requirement provided in § 172.301(a)(1). In addition, the reference to the bulk packaging marking requirements of § 172.302(b)(2) in § 172.514(c)(4) conflicts with § 172.336(d) identification number marking requirements, which states that when a bulk packaging is labeled instead of placarded in accordance with 
§ 172.514(c), identification number markings may be displayed on the package in accordance with the marking requirements of § 172.301(a)(1). 
In the NPRM, we proposed to clarify 
that the proper shipping name and identification number marking size for an IBC that is labeled instead of placarded is at least 12 mm (0.47 inch), doing so by replacing the bulk package marking reference in § 172.514(c) with the non-bulk marking reference, specifically, § 172.301(a)(1). PHMSA received four comments from ACA, DGAC, DOW, and URS providing support for this international harmonization action. In their comments DGAC, DOW, and URS all correctly point out that the UN Model Regulations, IMDG Code, and ICAO TI require a 12 mm (0.47 inch) minimum height requirement for the identification number on an IBC that is labeled rather than placarded, although, a minimum height for the proper shipping name is not prescribed. The DGAC and DOW suggested § 172.514(c) be revised by removing the words ‘‘size requirements’’ from the proposed text which currently reads ‘‘. . . the IBC may display the proper shipping name and UN identification number markings in accordance with the size requirements of § 172.301(a)(1) . . .’’ Additionally, URS suggested that § 172.301(a)(1) should be revised to clarify that the size of the proper shipping name marking is not prescribed by the regulations. 
The intent of the proposed action was 
to clarify that IBCs that are labeled instead of placarded can be marked in accordance with the non-bulk size requirements in § 172.301(a)(1) consistent with international standards. As § 172.301(a)(1) does not prescribe a size requirement for the proper shipping name, only the UN identification number would need to meet the 12 mm requirement. In the § 172.514 preamble we inadvertently stated, ‘‘[I]n this rulemaking, we are proposing to clarify that the marking size requirement, for both the proper shipping name and identification number, is at least 12 mm (0.47 inch) for an IBC that is labeled instead of placarded.’’ We agree with the comments from DGAC, DOW, and URS; thus, in this final rule, PHMSA is revising § 172.514(c)(4) for clarity as suggested by both DGAC and DOW. As § 172.301(a)(1) does not impose a size requirement for a proper shipping name, the removal of the words ‘‘size requirements’’ from § 172.514(c) clarifies that the 12 mm (0.47 inch) size requirement prescribed in 
§ 172.301(a)(1) applicable to UN identification numbers does not also apply to the proper shipping name. The 
reduced minimum marking size will alleviate the existing discrepancy 
between §§ 172.514(c)(4) and 172.336(d) and decrease frustration of shipments by harmonizing with international regulations, thus ensuring IBCs marked in accordance with these regulations are consistent with the HMR. 
Part 173 Section 173.4a 
Section 173.4a prescribes the 
requirements for excepted quantities of 
hazardous materials. The excepted quantities provisions were added to the HMR under an international harmonization final rule published on January 14, 2009 [Docket Nos. PHMSA– 2007–0065 (HM–224D) and PHMSA– 2008–0005 (HM–215J); 74 FR 2254, effective February 13, 2009]. Excepted quantities provisions in § 173.4a are intended to be consistent with the existing exception in the ICAO TI. Paragraph (a) states that excepted quantities of materials other than articles transported in accordance with this section are not subject to any additional requirements of this subchapter except for. The language is unclear as to whether articles (including aerosols) may use the excepted quantities provisions. As a result, PHMSA is revising this paragraph to clarify that articles (including aerosols) are not eligible for excepted quantity reclassification under § 173.4a, although some aerosols are eligible to be shipped as small quantities by highway and rail in § 173.4. This will eliminate confusion as to the status of articles (including aerosols) in the context of this exception, while providing consistent language structure with Part 3, Chapter 5, Section 5.1 of the ICAO TI. 
Section 173.24a 
Section 173.24a prescribes additional 
general requirements for non-bulk 
packages. Paragraph (c)(1)(iv) provides the quantity limits for mixed contents packages (when multiple hazardous materials are packed within the same package) transported by aircraft. In this rulemaking, we are clarifying that the requirements provided in paragraph (c)(1)(iv) do not apply to limited quantity materials packaged in accordance with § 173.27(f)(2). This change is for clarification purposes only. Misapplication of § 173.24a(c)(1)(iv) would be duplicative and, in certain cases, would place unintended restrictions on the net quantity of hazardous materials per package.

Section 173.27 
Section 173.27 prescribes general 
requirements for the transportation of 
hazardous material by aircraft. Paragraph (f)(2) contains the provisions for limited quantities but does not expressly address limited quantity packages of mixed contents. PHMSA received a request for a letter of interpretation (Ref. No. 13–0094) to clarify, for transportation by aircraft, the applicable section to reference. Specifically, the requester asked whether Table 3 in § 173.27(f)(3) or the general provisions in § 173.24a(c)(1)(iv) should be used when determining the maximum net quantity of each inner and outer packaging for limited quantity packages of mixed contents. In response, we stated that, as provided in § 173.27(f)(2), when a limited quantity of a hazardous material is packaged in a combination packaging and is intended for transportation aboard an aircraft, the inner and outer packagings must both conform to the quantity limitations set forth in Table 3, which provides the maximum net quantity of each inner and outer packaging for materials authorized for transportation as a limited quantity by aircraft. For mixed contents of limited quantities by air, the shipper must comply with the maximum authorized net quantity of each outer package (Column 4 of 5 in Table 3) and ensure that the total net quantity does not exceed the lowest permitted maximum net quantity per package as shown by hazard class or division for the hazardous materials in the mixed contents package. 
In this rulemaking, we are revising 
§ 173.27(f)(2)(i) to clarify that the maximum net quantity for limited quantity packages of mixed contents must conform to the quantity limitations provided in Table 3 of § 173.27(f)(3). PHMSA received one comment from UPS providing support for this revision. 
Section 173.150 
Section 173.150 provides exceptions 
for Class 3 (flammable and combustible 
liquid) hazardous materials. The requirements for combustible liquids in bulk packagings are found in § 173.150(f)(3). Although placarding under subpart F of part 172 is specified as a requirement in § 173.150(f)(3)(iv), registration requirements of § 107.601 are not included among the subject requirements. Given that § 173.150(f)(3) provides a list of subject requirements for combustible liquids in bulk packaging, PHMSA is revising this section through additions of a new subparagraph § 173.150(f)(3)(xi) stating that the registration requirements in subpart G of part 107 are also 
applicable, for bulk packagings only. PHMSA is also revising § 173.150(f)(3)(ix) and (x) for punctuation applicable to the listing of requirements. PHMSA received one comment from ACA providing support for the amendments as proposed. 
Section 173.159 
Section 173.159 prescribes 
requirements applicable to the 
transportation of electric storage batteries containing electrolyte acid or alkaline corrosive battery fluid (i.e., wet 
batteries). This section outlines packaging requirements, exceptions for highway or rail transport, and tests that batteries must be capable of withstanding to be considered as non- spillable. However, there is no authorization to transport nor are there any requirements or instructions for shippers of damaged or leaking wet batteries on how to prepare these items for transport. PHMSA received a request for a letter of interpretation (Ref. No. 06–0031) to clarify whether a shipper of a damaged wet battery may utilize the exception from full regulation provided in § 173.159(e). In response, we stated that a damaged battery may be shipped in accordance with § 173.159(e) provided: (1) It has been drained of battery fluid to eliminate the potential for leakage during transportation; (2) it is repaired and/or packaged in such a manner that leakage of battery fluid is not likely to occur under conditions normally incident to transportation; or 
(3) the damaged or leaking battery is transported under the provisions of § 173.3(c). 
PHMSA proposed adding a new 
paragraph (j) to § 173.159 to address this provision. However, a final rule published January 21, 2016 [Docket No. PHMSA–2013–0042 (HM–233F); 81 FR 3635] added a paragraph (j) to account for nickel cadmium batteries containing liquid potassium hydroxide. Therefore, all references to the previously proposed paragraph (j) will be to the new paragraph (k). 
PHMSA received positive feedback 
from commenters with the ATA, the UPS, the USWAG, and Veolia voicing general support for this amendment. Veolia requested that ‘‘cargo vessel’’ be added as a mode of transportation; however, as this was not proposed and that inclusion would need an analysis from both PHMSA and the USCG, and we will not be authorizing vessel transportation in this final rule. 
The Battery Council International 
(BCI) also commented on this provision. While they voiced strong support for the creation of a new paragraph to address damaged wet batteries, they had concerns that the proposed regulatory text was unclear, did not take into account the industry standard, and may inadvertently eliminate existing exceptions for wet batteries. To supplement their comments, a meeting was requested by representatives of BCI with PHMSA to clarify their comments. Notes from that August 11 meeting can be found in the docket for this rulemaking. The BCI’s primary concern is that a different packaging method referenced in previous PHMSA letters of interpretation (Ref. Nos. 09–0227 and 06–0062) that utilizes leak-proof packaging in other than an intermediate/outer configuration ( i.e., 
single polyethylene bag) is absent from paragraph (j). BCI asserts that the single polyethylene bag method is sufficient to prevent leakage of the battery acid during transportation and that changing this standard industry practice will be highly disruptive, costly, and likely to result in considerable confusion. During the meeting, it emphasized that this was the predominant method of transporting damaged wet batteries by a vast majority of industry. 
PHMSA agrees with BCI’s concerns 
and it was not our intent to undo progress made to address safety concerns by industry and PHMSA in the past by not allowing for this packaging configuration. Therefore, we are amending paragraph (k) (i.e., previously 
proposed paragraph (j)) to allow for this packing method. PHMSA believes that public safety would be better served by allowing the use of a method that is known and widely used by industry, that has a strong safety record for transporting damaged wet batteries, and on which affected hazmat employees are trained. The BCI further points out confusion in the proposed regulatory text in paragraphs (j)(2) and (3), stating that it is unclear how a shipper could comply with the packaging requirement in § 173.159(j)(2) without also complying with § 173.159(j)(3). PHMSA agrees with this comment; although, paragraphs (j)(2) and (3) are intended to be used in tandem, they currently appear to be separate conditions for transport. Therefore, we are amending the regulatory text to consolidate the previously proposed (j)(2) and (3) into one paragraph, now (k)(2). Lastly, BCI requests that clarification be added to ensure that there is no confusion that the batteries shipped under this paragraph are still eligible to be shipped using the exception found in § 173.159(e). PHMSA agrees. It was never our intent to prohibit the use of this exception, and it was an oversight

in the NPRM not to specify this. 
Therefore, we are including a provision to clarify the eligibility of damaged wet batteries for exception under paragraph (e) when transported in accordance with § 173.159(k). 
PHMSA is adding a new paragraph (k) 
in § 173.159 to address the need for provisions that allow shippers to prepare for transport and offer into transportation damaged wet electric storage batteries for purposes of recycling. Note that in addition to the conditions listed in paragraph (k), damaged wet electric storage batteries must also meet requirements of § 173.159(a). 
PHMSA is reinserting language into 
§ 173.159(e)(4) of the HMR indicating that the transport vehicle may not carry material shipped by any person other than the shipper of the batteries. This language was inadvertently deleted from the HMR when PHMSA published a final rule titled ‘‘Hazardous Materials: Reverse Logistics’’ under Docket HM– 253 (81 FR 18527; March 31, 2016). As revised by HM–253, § 173.159(e)(4) now states that a carrier may accept shipments of batteries from multiple locations for the purpose of consolidating shipments of batteries for recycling, which creates confusion in the context of the section. The intent of the HM–253 final rule was to allow carriers to consolidate shipments of batteries from multiple locations for the purpose of recycling. To correct this inadvertent deletion, in this final rule 
we are revising § 173.159(e)(4) by retaining the previous text and providing a clear exception when batteries are consolidated for recycling. 
Section 173.166 
Section 173.166 prescribes 
requirements applicable to the 
transportation of safety devices. In a final rule published on July 30, 2013 [Docket No. PHMSA–2010–0201 (HM– 254); 78 FR 45880], PHMSA revised the requirements applicable to these materials. Among the changes made was the adoption of Special Permit DOT–SP 12332 into the HMR. This special permit excepted Class 9 air bag inflators, air bag modules, or seat-belt pretensioners assigned to UN3268 from the requirement to provide the EX number (i.e., the approval number) on 
the shipping paper. 
Under § 173.166, paragraph (e)(6) 
authorizes packaging alternatives for air bag inflators, air bag modules, and seat- belt pretensioners that have been removed from, or were intended to be used in, a motor vehicle, as well as those devices that meet the requirements for use in the United States and are being transported to 
recycling or waste disposal facilities. When adopted in HM–254, a provision in § 173.166(e)(6) stated ‘‘for domestic transportation by highway,’’ thereby limiting the use of this exception to ground transport, yet DOT–SP 12332 specifically permitted transport by ‘‘cargo vessel’’ as an authorized mode of transportation. For greater consistency with the special permit language adopted in HM–254, PHMSA is revising paragraph (e)(6) to add the words ‘‘or cargo vessel,’’ and as a result, PHMSA received one comment from Veolia providing support for this revision. Veolia noted that this revision will remove the administrative burden from both PHMSA and the Special Permit holders necessary for maintaining the special permit. 
Sections 173.170 and 173.171 
Sections 173.170 and 173.171 
prescribe exceptions for the 
transportation of black powder for small arms classed as a Division 1.1 explosive and the transportation of smokeless powder for small arms classed as a Division 1.3 or Division 1.4 explosive. These exceptions permit these materials to be reclassed as Division 4.1 flammable solid material for domestic transportation. In both sections, the total quantity of black or smokeless powder for small arms is limited to 45.4 kg (100 pounds) net mass in a motor vehicle (other modes are authorized as well). PHMSA believes the exception should be updated to account for modern highway transportation. Currently, the HMR defines ‘‘motor vehicle’’ in § 171.8 to include a vehicle, machine, tractor, trailer, or semitrailer, or any combination thereof. The use of the term in this exception limits a carrier with multiple trailers to 100 pounds total of black or smokeless powder, reclassed as Division 4.1. Carriers who commonly transport double- or triple- trailer loads by highway may find it difficult to ensure that each trailer contains an amount of black or smokeless powder, reclassed as Division 4.1 that would keep the total quantity in all trailers under 100 pounds. 
PHMSA believes the term ‘‘motor 
vehicle’’ should be replaced with 
‘‘transport vehicle’’ in the context of this exception and that doing so will not decrease the level of safety for the transport of these materials. The term ‘‘transport vehicle’’ is defined in § 171.8 as a cargo-carrying vehicle, such as an automobile, van, tractor, truck, semitrailer, tank car, or rail car, used for the transportation of cargo by any mode. Each cargo-carrying body (a trailer, a rail car, etc.) is a separate transport vehicle. Changing the term ‘‘motor vehicle’’ to 
‘‘transport vehicle’’ would reflect a consistency in the ability to use exceptions for black or smokeless powder with the other modes, such as rail and vessel, whereby each rail car or freight container is permitted to have 100 pounds total. 
In the NPRM, PHMSA solicited 
comment from stakeholders on this issue and requested any available data relating to incidents involving transport of black or smokeless powder for small arms reclassed as Division 4.1 by motor vehicle. PHMSA received four comments from ATA, DGAC, SAAMI, and UPS in support of this revision. The SAAMI, noted,, ‘‘[w]e are aware of no 
incidents involving transporting black or smokeless powder for small arms reclassed as Division 4.1 by motor vehicle. These products are subject to a testing regime to ensure that they meet the rigid requirements for transport as a flammable solid.’’ Thus, in this final rule, PHMSA is revising §§ 173.170 and 173.171 as proposed in the January 23, 2015 NPRM to replace the term ‘‘motor vehicle’’ with ‘‘transport vehicle.’’ 
Section 173.199 
Section 173.199 prescribes the 
packaging requirements for Category B 
infectious substances. Paragraph (a)(4) of this section requires that the packaging be capable of successfully passing the drop test in § 178.609(d) and the steel rod impact test in § 178.609(h) at a drop height of at least 1.2 meters (3.9 feet). 
PHMSA received a request for a letter 
of interpretation (Ref. No. 07–0018) regarding the test requirements in § 173.199(a)(4). The request pointed out that in the preamble to the final rule published on June 2, 2006 [Docket No. PHMSA–2004–16895 (HM–226A); 71 FR 32244] states that Category B packagings must be capable of passing a drop test, but need not be capable of passing a puncture or other performance test. The requester asked if the regulatory text requiring the steel rod impact test for this packaging was an error. 
As we clarified in our response, 
PHMSA did not intend to require the steel rod impact test in § 178.609(h) for a packaging used to transport a Category B infectious substance. Therefore, in this rulemaking, we are revising the provisions in § 173.199(a)(4) by removing the reference to the steel rod impact test in § 178.609(h). 
Section 173.216 
Section 173.216 establishes the 
transportation requirements for 
asbestos. Paragraph (c) of this section

2_Original.pdf. provides packaging requirements for 
asbestos including both ‘‘bulk’’ and ‘‘non-bulk’’ packaging options. 
PHMSA received a request for a letter 
of interpretation (Ref. No. 11–0169) regarding the applicability of bulk and non-bulk packaging instructions for asbestos. The letter expressed confusion regarding whether § 173.216 should apply to both ‘‘bulk’’ and ‘‘non-bulk’’ packages of asbestos, because as the requester noted in the letter, the § 172.101 HMT entry for ‘‘Asbestos,’’ NA2212 refers to packaging instructions specified in § 173.216 for non-bulk packaging requirements and § 173.240 for bulk packaging requirements. It was also noted in the letter that some of the packaging options specified in § 173.216 are considered bulk packagings. 
PHMSA acknowledged that some of 
the packaging options provided in § 173.216(c) meet the bulk packaging definition specified in § 171.8 and, therefore, would be considered a bulk packaging for transportation purposes. In this rulemaking, we are revising the 
bulk packaging section reference in Column (8C) of the HMT to add a reference to ‘‘216’’ for the table entries associated with the following identification numbers: NA2212, UN2212, and UN2590. This revision will: (1) Eliminate the confusion pertaining to authorized bulk packaging specifications contained in a section previously only referenced in the authorized non-bulk Column (8B) of HMT and (2) allow for the continued use of bulk packages in § 173.240. 
Section 173.225 
Section 173.225 contains the 
packaging requirements and other 
provisions applicable to the transportation of organic peroxides. Paragraph (d) of this section contains the Packing Method table, which provides packagings authorized for organic peroxides and the maximum quantity permitted in each package or packaging. The table is missing pertinent information, so PHMSA is revising the table to add a reference to Note 1 for OP2, which states that if two values are given, the first applies to the maximum net mass per inner packaging and the second to the maximum net mass of the complete package. Additionally, PHMSA is revising the maximum quantity for solids and combination packagings (liquid and solid) for OP4 to read as ‘‘5/25’’ kg instead of only ‘‘5.’’ 
Section 173.301 
Section 173.301 applies to general 
requirements for shipment of 
compressed gases and other hazardous materials in cylinders, UN pressure receptacles, and spherical pressure vessels. Paragraph (g) of this section describes the requirements to manifold cylinders in transportation. A manifold system is a single pipe or chamber connected to a group of cylinders, which allows for a single point of loading and unloading. 
Incidents investigated by the NTSB 
have highlighted potential risks when transporting manifolded acetylene trailers.
3These incidents included 
overturned vehicles and two unloading releases. As a result of the impact caused by ejection of the cylinders from the vehicle during overturn incidents, cylinders have shown signs of broken valves, burst heads, burst walls, as well as bulging and denting of the walls. The impact resulting from the ejection of the cylinders from the vehicle also can cause the valves to break, which may ignite the acetylene. The NTSB’s investigation also concluded that the unloading sequence is occasionally done out of order from what is specified in the standard operating procedures and that this can be a contributing factor to incidents. 
The NTSB has issued two Safety 
Recommendations
4to PHMSA based on 
recent incidents involving manifolded acetylene trailers: 
H–09–01: Modify 49 CFR 173.301 to 
clearly require (1) that cylinders be securely 
mounted on mobile acetylene trailers and other trailers with manifolded cylinders to reduce the likelihood of cylinders being ejected during an accident and (2) that the cylinder valves, piping, and fittings be 
protected from multidirectional impact forces that are likely to occur during highway accidents, including rollovers. 
H–09–02: Require fail-safe equipment that 
ensures that operators of mobile acetylene trailers can perform unloading procedures only correctly and in sequence. 
Given the results of the NTSB 
investigations, as well as the associated 
safety risks of mobile acetylene trailer overturns and unloading operations, PHMSA proposed in the NPRM to incorporate by reference in § 171.7 of the HMR the CGA G–1.6–2011, Standard for Mobile Acetylene Trailer Systems, Seventh Edition, copyright 
2011. CGA G–1.6 would serve to address the NTSB Safety Recommendations specific to mobile acetylene trailers. This pamphlet was updated by the CGA with input from both PHMSA and the industry to address cylinder securement under accident conditions, valve protection 
from multidirectional impact forces, and unloading procedures specific to mobile acetylene trailers. 
Specifically, PHMSA proposed to 
incorporate the CGA pamphlet into § 171.7 and to revise § 173.301(g)(1)(iii) to indicate that mobile acetylene trailers must be maintained, operated, and transported in accordance with CGA Pamphlet G–1.6. In addition, PHMSA sought specific comment on the inclusion of CGA Technical Bulletin (TB) TB–25 to address structural integrity requirements. PHMSA also proposed to revise § 177.840 by adding paragraph (a)(3) to state that cylinders containing acetylene and manifolded as part of a mobile acetylene trailer system must be transported in accordance with § 173.301(g) to ensure that this requirement is addressed in the carriage by highway portion of the HMR. 
PHMSA received two comments on 
this provision. The CGA, who petitioned to incorporate by reference CGA Pamphlet G–1.6, stated continued support for the adoption of this provision. Additionally, they comment that TB–25 ought not to be included in the adopted regulations, stating that it would be incorrectly applied. TB–25 addresses tubes that are mounted horizontally on a trailer chassis whereas acetylene cylinders are required to be mounted vertically with individual valve protection. Thus, while tubes are permanently mounted onto a trailer chassis, acetylene cylinders are not permanently attached to the trailer to allow for periodic maintenance (i.e., resolventing). 
In its comment, the NTSB agrees with 
PHMSA’s intent to address mobile acetylene trailers but states that CGA Pamphlet G–1.6 does not fully address accident impact protection from multidirectional forces that are likely to be encountered during highway accidents, including rollover. Additionally, they believe TB–25 should be included to address manifolded acetylene cylinders and state that a revision to TB–25 to include vertically-mounted, manifolded cylinders would provide a standard for accurate and verifiable performance testing, analytical methods, or a combination thereof, to prove the adequacy of mobile acetylene trailer 
designs in both normal operation and accident conditions. The NTSB also disagrees with PHMSA that the proposed changes address cylinder securement, vehicle accident impact, or rollover protection as recommended in Safety Recommendation H–09–01. Lastly, it states that CGA Pamphlet G– 1.6 does not mandate operator 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00019 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335502 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
equipment that would require them to 
perform unloading procedures in the correct sequence and that it only requires that instructions are readily available to the operator. 
PHMSA appreciates both CGA and 
NTSB’s comments on this provision. We recognize NTSB’s concerns regarding the nature of its recommendations and what was proposed in the NPRM. Its comments demonstrate that further examination of this issue regarding performance in accident conditions is necessary. While we cannot adopt additional provisions at this time as they are beyond the scope of this rulemaking, we will work with both the NTSB and the CGA to address remaining concerns and additional action may be taken in a future rulemaking. However, at this time PHMSA is adopting as proposed the incorporation by reference of CGA Pamphlet G–1.6. 
Section 173.306 
Section 173.306 provides exceptions 
from the HMR for compressed gases, 
including aerosols, when transported in limited quantities. In a final rule published May 14, 2010 [Docket No. PHMSA–2009–0289 (HM–233A); 75 FR 27205], PHMSA added a new paragraph (k) to § 173.306 adopting provisions from DOT–SP 12842. These provisions authorized an increase in gross weight per package for the purpose of packaging discarded empty, partially used, and full aerosol containers to be transported to a recycling or disposal facility. 
PHMSA received a request for a letter 
of interpretation (Ref. No. 12–0004) 
seeking confirmation that aerosols shipped for disposal or recycling in compliance with § 173.306(k) are permitted the same exceptions (i.e., the 
marking and labeling requirements of part 172, subparts D and E, respectively, and shipping paper requirements, unless it is a hazardous waste or hazardous substance, of part 172, subpart C) granted under §§ 173.306(i) and 173.156(b) without being reclassified as an ORM–D material. The requester also pointed out that under DOT–SP 12842, aerosols shipped for disposal or recycling were excepted from the marking, labeling, and shipping paper requirements, unless they were considered a hazardous waste or hazardous substance, without being reclassified as an ORM–D material. 
In response to the NPRM, PHMSA 
received three comments on this proposed change. Two commenters, the USWAG and Veolia voiced general support for the revision. However, both Veolia and ACA noted a mistake in the preamble language of the NPRM and believe the applicable marking section referenced in the discussion was in error and should be § 172.315(a)—for modes other than air transport, not paragraph (b). Though, Veolia does note that the proposed revised text included by PHMSA in § 173.306(k)(3) is correct by referencing § 172.315(a). PHMSA appreciates the comment from Veolia and agrees that they are correct. Additionally, in its comment, ACA questions the need for the proposed marking requirement in § 173.306(k)(4) requiring that limited quantity packages containing aerosols for recycling or disposal conforming to the provisions of paragraph (a)(3), (a)(5), or (b)(1) must also be marked ‘‘INSIDE CONTAINERS COMPLY WITH PRESCRIBED REGULATIONS’’ in addition to marking in accordance with § 172.315(a). The ACA commented that the ‘‘INSIDE CONTAINERS COMPLY WITH PRESCRIBED REGULATIONS’’ marking is explicitly not required by § 173.306(i) and therefore an original (not for recycling or disposal) shipment of aerosols meeting the requirements of a limited quantity is not required to be marked ‘‘INSIDE CONTAINERS COMPLY WITH PRESCRIBED REGULATIONS’’. The ACA contends that when an aerosol is ready for disposal or recycling it is presumably empty or less than full and that the risk is lower, and as such, it questions the need for this additional marking. The ACA commented that this situation is somewhat confusing and will likely lead to mistakes and in addition, will require shippers of aerosols to stock two different boxes or a roll of labels for the disposal or recycling shipments, incurring additional costs for very low- risk commodities. 
PHMSA agrees that the proposed 
marking of packages with ‘‘INSIDE CONTAINERS COMPLY WITH PRESCRIBED REGULATIONS’’ is not necessary, as the presence of a § 172.315(a) limited quantity mark on a package prepared in accordance with § 172.306(k) sufficiently communicates conformance with applicable requirements, and although PHMSA does not necessarily agree that the risk of empty or partially full aerosols is lower due to the much larger quantity authorized per package (i.e., 500 kg 
gross) compared to the standard limitation of 30 kg gross, we believe the safety concern of the larger quantity is offset by the conditions of the exception in § 172.306(k), specifically, protecting or removing the valve stem of the aerosols and limiting carriage to private or contract carriers, or under exclusive use service by common carriers. The former protects against the release of contents and while the latter prevents introduction into common transportation channels where transport personnel do not have as much expertise and knowledge of the package and its contents. Therefore, in this rulemaking, we are revising § 173.306(k) by clarifying that aerosols shipped for recycling or disposal by motor vehicle, under the specific conditions provided in § 173.306(k), are afforded the applicable exceptions provided for ORM–D materials granted under §§ 173.306(i) and 173.156(b). In addition, § 173.306(k) packages must be marked in accordance with § 172.315(a). 
Sections 173.314(h) and 173.315(b)(1) 
Section 173.314 establishes 
requirements for compressed gases in 
tank cars and multi-unit tank cars, and § 173.315 establishes requirements for compressed gases in cargo tanks and portable tanks. PHMSA is aware of several incidents possibly attributed to either the under-odorization or odorant fade of LPG. Although not transportation related, most notable of these incidents is one that happened in Norfolk, MA on July 30, 2010, where an explosion occurred at a residential condominium complex that was under construction. Emergency responders from 21 cities and towns deployed personnel to the accident site. The accident resulted in seven injuries and one fatality. 
The subsequent investigation raised 
questions as to whether there was a sufficient level of odorant in the LPG contained in the on-site storage tanks. In accordance with Federal and State laws and regulations, LPG intended for use by non-industrial entities is generally required to be odorized, or stenched, to enable the detection of any unintended release or leak of the gas. LPG is highly flammable, and is dangerous to inhale in large quantities; thus the addition of an odorant is a safety precaution that helps warn those in the area that a release of gas has occurred. In the Norfolk incident, there was no noticeable evidence of odorant that would indicate a leaking. PHMSA has consulted with stakeholders from industry, fire fighter associations, and other regulatory agencies in order to better understand the root cause of incidents like the one in Norfolk. Although additional research may be necessary in order to come to more definitive conclusions, PHMSA has identified the following situations in which the risks of under-odorization or odorant fade are more likely to occur: 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00020 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335503 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
Injection Process: On December 13, 
2012, PHMSA met with representatives 
from the NPGA to gain a better understanding of the LPG odorization process. During this meeting, representatives from the NPGA stated that the most common method for the odorization of LPG is through an automated system. However, the NPGA also noted there are situations where the odorization process is manually performed. Preliminary investigations into the Norfolk, MA incident suggest that the lack of sufficient odorization rendered the LPG undetectable when the on-site storage tank began to leak. In situations where the injection process is not fully automated, the potential for human error may increase the possibility of under-odorization. We believe that the insufficient level of odorant in the LPG contained in the on- site storage tank involved in the Norfolk, MA incident was likely a major contributing factor in limiting the ability of on-site personnel to readily detect the leak. 
New Tanks or Freshly Cleaned Tanks: 
During our meetings with various stakeholders, several indicated that a phenomenon known as ‘‘odor fade’’ may be a problem when new or recently cleaned tanks are used. New or recently cleaned tanks may absorb the odorant into the metal shell of these tanks leading to an ‘‘odorant fade,’’ thus limiting the effectiveness of the remaining odorant in the LPG. 
Odorization Standards: The 
odorization of LPG is addressed by Federal and State laws and regulations, as well as by generally accepted industry standards and practices. When offered and transported in commerce, the HMR specifies that all LPG in cargo and portable tanks be effectively odorized using either 1.0 pound of ethyl mercaptan, 1.0 pound of thiopane, or 1.4 pounds of amyl mercaptan per 10,000 gallons of LPG, in the event of an unintended release or leak to indicate the presence of gas. The HMR does not, however, require LPG to be odorized if odorization would be harmful in the use or further processing of the LPG, or if odorization will serve no useful purpose as a warning agent in such use or further processing. Essentially, this exception applies to 
LPG being transported to industrial end- users. 
In response to the NPRM, PHMSA 
received comments from the Massachusetts Department of Fire Services, the NASFM, the NTSB, the IAFC, the NPGA, Trammo Inc., and the New Hampshire Office of the State Fire Marshall on the proposed odorization requirements. All of the commenters supported the development of an 
odorization standard for rail tank cars as it exists for cargo tanks and portable tanks. Additionally, support for qualitative testing to address under- odorization or odorant fade was voiced. 
The Massachusetts Department of Fire 
Services generally support PHMSA’s proposal to address odorization of LPG in both cylinders and rail cars, as well as the creation of a performance standard to address issues of under- odorization and odorant fade of LPG in transportation. They believe that the proposals could be strengthened in two ways: (1) Mandate qualitative testing equivalent to the Code of Massachusetts Regulations, which specifies the tests that can be used to satisfy this requirement; and (2) mandate recordkeeping requirements that can be made available upon request. Records should include: The process of odorization, testing and test results, and if necessary, remediation by injection of additional odorant. The odorization in cylinders is not being adopted as proposed. While PHMSA appreciates the prescriptive additional requirements for odorization offered in the comment from the Massachusetts Department of Fire Services we disagree with specifying the tests that can be used and requiring recordkeeping. These measures were not proposed in the NPRM and PHMSA sees specifying the tests as a limiting factor to addressing odorization qualitative testing. While we do not take issue with using the tests outlined in the Code of Massachusetts Regulations, we are not prescribing specific tests. In addition, the requirement for recordkeeping was not proposed in the NPRM, so obligatory paperwork burdens were not accounted for: PHMSA is required by Federal law to reduce the paperwork burdens it imposes on private citizens and businesses. Accordingly, we do not agree that the safety benefits achieved by requiring recordkeeping are justified. These comments by the Massachusetts Department of Fire Services were echoed by the NASFM, the IAFC, and the New Hampshire Office of the State Fire Marshall. 
As discussed in the section 
referencing the Provisions Not Adopted in This Final Rule, the NPGA opposed an odorization testing requirement for cylinders and cargo tanks. Although PHMSA disagrees with NPGA that cargo tanks should be excluded from the requirements to address odorant fade or under-odorization, we agree with its comment that it should be addressed ‘‘upstream’’ in transportation. Therefore, 
we are only applying the revised text in § 173.315(b)(1) to cargo tanks and portable tanks being offered for transport from a refinery, gas plant, or pipeline terminal. 
The NPGA also provided suggestions 
to improve the proposed § 173.314(h) language. It suggests deleting the references to thiophane and amyl mercaptan as these materials are no longer used as odorant in LPG. PHMSA agrees with this comment and will remove those references. Due to universal support by commenters for requiring an odorant performance standard as well as measures to address odorant fade and under-odorization in rail tank car tanks, we are adopting new § 173.314(h) provisions with minor changes. 
Trammo Inc. generally supported the 
proposed changes, but expressed concern about the odorization requirements regarding exporting propane. They note that odorized propane cannot be shipped internationally because it may be sold for industrial purposes for which odorization may be harmful, and that a small specialized fleet of refrigerated gas carriers refuse to carry odorized products because of persistent cargo residue and contamination. Trammo Inc. notes that receiving odorized propane would have negative consequences for the company and its customers. PHMSA notes these concerns; however, PHMSA points out that §§ 173.314(h) and 173.315(b)(1) provide an exception that addresses this scenario indicating that odorization is not required if harmful in the use or further processing of the liquefied petroleum gas or if odorization will serve no useful purpose as a warning agent in such use or further processing. This exception would apply to the exportation and further distribution of liquefied propane gas internationally if it cannot be offered as odorized. 
Part 175 Sections 175.1 and 175.9 
Section 175.1 describes the purpose, 
scope, and applicability of part 175 to 
air operations, specifically, the transportation of hazardous materials in commerce by air. Section 175.9 provides exceptions from regulation under the HMR for certain special aircraft operations. Specifically, paragraph (b)(4) of § 175.9 excepts hazardous materials carried and used during dedicated air ambulance, firefighting, or search and rescue operations. To clarify that these operations are not subject to the HMR when in compliance with applicable Federal Aviation Regulations (FAR; 14 CFR) and any additional Federal Aviation Administration (FAA) 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00021 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335504 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
requirements, PHMSA is adding a new 
paragraph (d) in § 175.1 stating that the HMR does not apply to dedicated air ambulance, firefighting, or search and rescue operations. This will eliminate any confusion that these air operations would otherwise be subject to requirements in the HMR (e.g., passenger notification requirements). PHMSA is also removing § 175.9(b)(4) for consistency. 
As with other conditional exceptions 
to the HMR, non-compliance with the FAR could subject operators to enforcement under the HMR, but PHMSA does not anticipate any adverse safety consequences with this proposed revision due to the existing training requirements in the FAR on the proper handling and stowage of hazardous materials carried onboard aircraft. 
The FAA and PHMSA recognize that 
certain operators do not solely utilize their aircraft for purposes under § 175.9(b)(4). Normal transport operations (i.e., the transport of 
passengers or cargo not required for performance of, or associated with, the specialized emergency function) would continue to be subject to the HMR. However, staging operations and other operations related to dedicated air ambulance, firefighting, or search and rescue operations are intended to be excepted from the HMR when in compliance with the FAR. We note the following definitions in FAA Order 8900.1 (Vol. 3, Chapter 14, Section 1, 3– 529(C)): 
(1) Firefighting. This term includes the 
drop of fire retardants, water, and smoke 
jumpers. It also includes the transport of firefighters and equipment to a fire or to a 
base camp from which they would be dispersed to conduct the firefighting activities. 
(2) Search and Rescue. Search and rescue 
is a term of art meaning aircraft operations that are flown to locate people who cannot be located from the ground. The term includes operations where the aircraft is indispensable to the search, or is the only feasible means of reaching the victim. Victims would be considered to be ‘‘associated with’’ the search and rescue operation. The term ‘‘search and rescue’’ does not include routine medical evacuation of persons due to traffic accidents and other similar incidents. 
Air ambulance operators are required 
by the FAR to utilize either Operational 
Specification (OpSpec) A021 (Helicopter Emergency Medical Services (HEMS) Operations) or A024 (Air Ambulance Operations—Airplane) and must obtain and adhere to the appropriate OpSpec to be excepted from the HMR. Section 175.8 
Section 175.8 provides exceptions 
from certain regulations for air carrier operator equipment and items of replacement. Paragraph (b)(1) provides that oxygen, or any hazardous material used for the generation of oxygen, for medical use by a passenger, which is furnished by the aircraft operator in accordance with certain FAR (14 CFR) requirements is not subject to the requirements of the HMR. The provisions of the FAR, at § 125.219, Oxygen for medical use by passengers, was inadvertently left out of paragraph (b)(1). In this rulemaking, we are revising paragraph (b)(1) by adding the appropriate FAR, part 125 citation. 
Section 175.10 
Section 175.10 provides exceptions 
for passengers, crewmembers, and air 
operators. Paragraph (a) of this section lists a number of hazardous materials that are permitted for carriage by passengers or crewmembers provided the requirements of §§ 171.15 and 171.16 and the conditions of this section are met. PHMSA is proposing revisions to some of these provisions to promote clarity. 
In paragraph (a)(6), hair curlers 
(curling irons) containing a hydrocarbon gas, such as butane, and carried in carry-on or checked baggage, are excepted from the requirements of the HMR. However, gas refills for such curlers are not permitted in carry-on or checked baggage. In this final rule, PHMSA is prohibiting such hair curlers in checked baggage due to the risk posed by flammable gases in an inaccessible compartment on a passenger-carrying aircraft. Flammable gases will burn if mixed with an appropriate amount of air and confined burning of a flammable gas can lead to detonation. As a result, we remain concerned with the flammability hazard posed by butane and other flammable gases and the ability of such gases to propagate or contribute to a fire in the cargo compartment of an aircraft. This concern is particularly relevant to carriage in checked baggage, where damage to the curling iron and the subsequent release of a flammable gas may occur if the baggage is mishandled or the article itself is compromised. 
Because of the risks posed by 
flammable gas, a number of safety requirements apply to cargo shipments of flammable gas on passenger-carrying aircraft. Most Division 2.1 flammable gas substances and articles are generally forbidden from transportation as cargo aboard passenger-carrying aircraft, and PHMSA’s prohibition of the carriage of butane-powered curling irons in 
checked baggage is consistent with this provision. In the area of aviation safety, where the high volume of travel and the catastrophic consequences of failure lead to a very low tolerance for risk, we firmly believe the known risks of flammable gas are sufficient basis for our decision. In the NPRM, we solicited public comment on any impact our proposed action may impose upon passengers, crew members, and air operators; however, PHMSA did not receive any comments. 
In paragraph (a)(22) of this section, 
non-infectious specimens transported in accordance with § 173.4b(b) (de minimus quantities) are permitted for carriage by passengers or crewmembers. PHMSA is clarifying this exception to include the phrase ‘‘in preservative solutions’’ to clarify the intended use of this exception. Non-infectious substances would not be subject to the HMR if they did not otherwise meet the definition of any other hazard classes. This clarification signals that the exception refers to specimens in solutions that may contain preservatives that are hazardous materials, such as formaldehyde and alcohol solutions. 
Additionally, PHMSA is revising 
paragraph (a)(24) of this section, which refers to small cartridges of carbon dioxide or other suitable gas of Division 2.2. The exception states that small cartridges fitted into devices with no more than four small cartridges are permitted. This is inconsistent with the ICAO TI, which permits cartridges for other devices indicating that spares are permitted. As § 175.10(a)(24) currently reads, there is no mention of spare cartridges. The HMR currently permits up to four small cartridges, and therefore, PHMSA is revising this paragraph to state that small cartridges 
fitted into or securely packed with devices with no more than four small cylinders of carbon dioxide or other suitable gas in Division 2.2 are permitted for carriage by passengers or crewmembers. This change harmonizes the exception with international standards to clarify that spares are permitted in addition to the cartridges already fitted into the device, provided they are securely packed with the devices for intended use. 
Section 175.75 
Section 175.75 describes the quantity 
limitations and cargo locations for 
carriage by aircraft. Paragraph (e)(2) excepts packages of hazardous materials transported aboard a cargo aircraft, when other means of transportation are impracticable or not available, in accordance with procedures approved 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00022 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335505 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
in writing by the FAA Regional or Field 
Security Office in the region where the operator is located, from the requirements of paragraphs (c) and (d) of § 175.75. PHMSA is revising this paragraph by removing the word ‘‘located’’ and replacing it with ‘‘certificated.’’ The words ‘‘or Field Security’’ are also removed. This amendment ensures that operators interact with the Hazardous Materials Division Manager (HMDM) who has already reviewed and recommended for approval the certificate’s hazmat-related manual(s) required under FAR § 121.135. The HMDM (or designee) will already have an understanding of the certificate’s operations and, as needed, will interact with the local resources and/or the operator’s certificate management team to assess the impracticability or lack of availability of other cargo operations—as well as what alternative procedures should be prescribed. 
Part 176 Section 176.30 
Section 176.30 prescribes the 
information required on dangerous 
cargo manifests for vessel transport. Paragraph (a)(4) requires ‘‘the number and description of packages (e.g., barrels, drums, cylinders, boxes, etc.) and gross weight for each type of packaging.’’ In this final rule, PHMSA is replacing the word ‘‘packaging’’ with ‘‘package,’’ as the term ‘‘packaging’’ refers to the means of containment and not the completed package. 
Part 177 Section 177.834 
Section 177.834 establishes general 
operational requirements for hazardous 
materials transportation by highway. Section 177.934(i) prescribes attendance requirements for loading and unloading operations. In a final rule published on January 21, 2016 [Docket No. PHMSA– 2013–0042 (HM–233F); 81 FR 3635], PHMSA codified DOT Special Permits 9874, 13190, 13424, 13959, 14141, 14150, 14680, 14822, 14827, and 14840 into § 177.834(i) that authorize ‘‘attendance’’ of the loading or unloading of a cargo tank by a qualified person observing all loading or unloading operations by means of video cameras and monitors or instrumentation and signaling systems such as sensors, alarms, and electronic surveillance equipment located at a remote control station. In the same final rule, PHMSA codified DOT Special Permits 13484 and 14447 also into § 177.834(i) that authorize ‘‘attendance’’ of the loading or unloading of a cargo tank through the use of hoses equipped with cable connected wedges, plungers, or flapper valves located at each end of the hose, able to stop the flow of product from both the source and the receiving tank within one second without human intervention in the event of a hose rupture, disconnection, or separation. The SPs prescribe inspection requirements and operational controls for use of the hoses. In the final rule, however, PHMSA inadvertently omitted the word ‘‘or’’ between each of the four acceptable methods of determining compliance with the attendance requirements adopted by the codification of the 12 special permits. Thus, in this final rule, PHMSA is inserting the word ‘‘or’’ between each acceptable method in § 177.834(i) as proposed in the January 30, 2015 NPRM. 
Section 177.848 
Section 177.848 addresses segregation 
requirements for hazardous materials 
transported by motor carrier. PHMSA received a request for a letter of interpretation (Ref. No. 09–0268) requesting clarification whether ‘‘Boosters, 1.1D, UN0042, PG II’’ and ‘‘Ammonium nitrate, 5.1, UN1942, PG III’’ can be transported in the same vehicle. The requester noted seemingly conflicting requirements in §§ 177.835 and 177.848 applicable to the segregation of ammonium nitrate fertilizer and explosive materials. 
Section 177.848(e) provides 
instructions for using the segregation table in § 177.848(d). Presently, under § 177.848(e)(5) assignment of note ‘‘A’’ authorizes ammonium nitrate (UN1942) and ammonium nitrate fertilizer to be loaded or stored with Division 1.1 or Division 1.5 (explosive) materials. However, § 177.835(c) provides that Division 1.1 or 1.2 (explosive) materials may not be loaded into or carried on any vehicle or a combination of vehicles under certain conditions outlined in paragraphs (c)(1) through (4). PHMSA clarified in the response letter that a Division 1.1 or 1.2 explosive may not be loaded into or carried on any vehicle or a combination of vehicles that does not conform to §§ 177.835(c)(1) through (4), regardless of the note ‘‘A’’ exception for UN1942 in § 177.848(e)(5). In this rulemaking, we are clarifying that the loading restrictions in § 177.835(c)(1) through (4) are applicable to § 177.848(e). 
Part 178 Section 178.65 
Section 178.65 applies to the 
manufacture of DOT Specification 39 non-reusable (non-refillable) cylinders. 
Paragraph (i) of this section describes the required markings for DOT 39 cylinders. The reference to § 178.35(h) in § 178.65(i)(1) is incorrect, as § 178.35(h) was removed under a final rule published July 20, 2011 [Docket No. PHMSA–2009–0151 (HM–218F); 76 FR 43509], which consolidated the inspector’s report requirements found in § 178.35(g) into paragraph (c)(4) of that section, moved the manufacturer’s report retention requirements into paragraph (g) and removed paragraph (h). In this final rule, PHMSA is revising § 178.65(i)(1) to correctly reference the manufacturer’s report requirements in § 178.35(g). 
Section 178.337–17 
Section 178.337–17 prescribes the 
marking requirements applicable to MC 
331 cargo tank motor vehicles. Paragraph (a) of this section outlines general requirements for marking of MC 331 cargo tank motor vehicles. PHMSA received a request for a letter of interpretation (Ref. No. 04–0206) to clarify the applicability of these markings in § 178.337–17(a). The request pointed out an incorrect use of the term cargo tank as it applies to the requirement for specification plates found in paragraph (a), which states that each cargo tank certified after October 1, 2004 must have a corrosion-resistant 
metal name plate (ASME Plate) and specification plate permanently attached to the cargo tank by brazing, welding or other suitable means on the left side near the front, in a place accessible for inspection. 
In response, we stated that an MC 331 
cargo tank must have a metal name plate (also referred to as an ASME plate) permanently attached to the cargo tank. In addition, an MC 331 cargo tank motor vehicle certified after October 1, 2004, must have a specification plate that includes the information specified in § 178.337–17(c). In this final rule, PHMSA is revising § 178.337–17(a) to eliminate confusion of the name plate and specification plate requirements. 
Section 178.345–3 
Section 178.345–3 prescribes general 
requirements for the structural integrity 
of specification cargo tanks. Paragraph (c)(1) of this section addresses stress in the cargo tank shell resulting from normal operating loadings. PHMSA published a final rule on October 2, 2013 [Docket No. PHMSA–2013–0158 (HM–244F); 78 FR 60745; effective October 1, 2013] intending to correct the formula presented in paragraph (c)(1) for the figure ‘‘S
S2’’ to read ‘‘SS2.’’ This 
correction correctly adjusted the

standard ‘‘2’’ in the term to be a 
superscript ‘‘2’’ but inadvertently 
adjusted the second ‘‘S’’ from a subscript ‘‘
S’’ to a standard ‘‘S.’’ This is 
incorrect, and in this final rule, PHMSA is revising this portion of the formula in § 178.345–3(c)(1) to read ‘‘S
S2’’. 
Section 178.955 
Section 178.955 prescribes the design 
and testing criteria for Large Packagings. Presently, if a manufacturer of a Large Packaging wishes to construct a Large Packaging that differs from a listed specification, there is no Associate Administrator approval provision outlined in the HMR. However, the HMR alludes to the need for an approval in the Large Packaging marking requirements in § 178.910(a)(1)(ii). The HMR have approval provisions in Part 178 for manufacturers of both non-bulk packagings and IBCs when constructing packagings that differ from listed specifications. In this rulemaking, we are proposing to include provisions consistent with the non-bulk packaging and IBC approval provisions for Large Packagings in § 178.955. Such Large Packagings must be shown to be equally as effective, and the testing methods used must be equivalent. This change resolves the issue with § 178.910(a)(1)(ii) and is consistent with both the UN Model Regulations and the IMDG Code, which prescribe approval provisions for non-bulk packagings, IBCs, and Large Packagings. 
Part 179 Section 179.13 
Section 179.13 includes limitations 
on rail tank car capacity and gross 
weight. With certain exceptions, this section generally limits the gross weight on rail of tank cars to 263,000 pounds. However, this section has been revised numerous times over the last several years. On January 13, 2009 [74 FR 1770], PHMSA added paragraph (b) to this section authorizing tank cars designed to transport poisonous-by-inhalation (PIH) materials and built with certain mandated safety improvements (tank cars meeting the specifications of § 173.244(a)(2) or (3) or § 173.314(c) or (d)) to have a gross weight on rail of up to 286,000 pounds provided any weight increase was not used to increase product capacity. Subsequently, in an effort to incorporate several widely used special permits providing relief from the gross weight limitations of § 179.13, PHMSA revised the section on May 14, 2010 [75 FR 27205], to provide FRA with the authority to approve the operation of tank cars containing materials other than PIH materials at gross weights of up to 286,000 pounds. FRA published notice of its approvals under this section on January 25, 2011 [76 FR 4250]. 
In 2011 [76 FR 51324; 51331], noting 
that the agency’s stated intent in the 2010 rule was to incorporate into the HMR existing special permits related to tank car gross weight for tank cars carrying both non-PIH materials and PIH materials by giving FRA authority to approve tank car weights up to 286,000 pounds for both types of tank cars, PHMSA proposed to revise § 179.13 to correct the omission of PIH material tank cars from FRA’s approval authority. However, when adopted as a final rule on June 25, 2012 [(HM–216B); 77 FR 37962; 37985], the regulatory language did not correct this inadvertent omission. Instead, in the final HM–216B rule, § 179.13 was revised to provide that tank cars designed to transport PIH materials and built with the required safety improvements set forth in § 173.244(a)(2) or (3) or § 173.314(c) or (d)) ‘‘may have a gross weight on rail of up to 286,000 pounds upon approval by the Associate Administrator for Railroad Safety, FRA.’’ 
As clearly demonstrated by the 2009 
and 2010 rules, it was not the intent of either PHMSA or FRA to require FRA approval of tank cars built to the enhanced standards of §§ 173.244(a)(2) or (3) or 173.314(c) or (d) for those cars to operate at a gross rail load of 286,000 pounds. Accordingly, in this final rule PHMSA is revising § 179.13 to correct this error by (1) making it clear that tank cars containing PIH materials built to the enhanced standards of § 173.244(a)(2) or (3) or § 173.314(c) or (d) do not need FRA approval to operate at gross rail loads of up to 286,000 pounds and (2) providing for FRA approval of tank cars containing PIH materials that do not meet the enhanced standards to operate at gross rail loads of up to 286,000 pounds. PHMSA received one comment from The Chlorine Institute in support of this revision. 
Part 180 Section 180.209 
Section 180.209 prescribes 
requalification requirements for DOT 
specification cylinders. Paragraph (j) contains a reference to an obsolete special provision. In a January 7, 2013 final rule [Docket No. PHMSA–2009– 0126 (HM–215K); 78 FR 1101], we removed and relocated regulatory text from § 172.102(c)(1) Special Provision 18 to § 173.309(a), which prescribes the conditions when specification cylinders may be described, offered, and transported in commerce as fire extinguishers. In relocating the text, PHMSA did not update this section to reflect the change. In this final rule, we are correcting this inconsistency by replacing the reference to § 172.102(c)(1) Special Provision 18 with § 173.309(a). 
V. Regulatory Analyses and Notices A. Statutory/Legal Authority for This 
Rulemaking 
The Federal Hazardous Materials 
Transportation Law (49 U.S.C. 5101– 5128) authorizes the Secretary of Transportation (Secretary) to ‘‘prescribe regulations for the safe transportation, including security, of hazardous material in intrastate, interstate, and foreign commerce.’’ The Secretary delegated this authority to PHMSA in 49 CFR 1.97(b). If adopted as proposed, this final rule would make miscellaneous amendments to the HMR, correct errors in the § 172.101 HMT and corresponding special provisions, and respond to NTSB Safety Recommendations related to the safe transportation of manifolded acetylene cylinders. 
Additionally, this final rule will 
respond to petitions for rulemaking related to the allowable format for emergency telephone numbers on shipping papers; relax the pressure test interval for certain cargo tanks in dedicated propane service; enhance the safe packaging for nitric acid; clarify the testing requirements for specification cargo tank pressure relief devices; harmonize the hazard communication requirements for poisonous-by- inhalation materials transported by vessel; and eliminate a potentially confusing packing group designation for certain organic peroxides, self-reactive materials, and explosives. These amendments clarify regulatory requirements and, where appropriate, decrease the regulatory burden without compromising the safe transportation of hazardous materials in commerce. 
B. Executive Order 12866, Executive 
Order 13563, and DOT Regulatory Policies and Procedures 
This final rule is not considered a 
significant regulatory action within the meaning of Executive Order 12866 (‘‘Regulatory Planning and Review’’) and the Regulatory Policies and Procedures of the Department of Transportation [44 FR 11034]. 
In this final rule, we amend 
miscellaneous provisions in the HMR for clarification and relaxation of overly burdensome requirements, with the intent of, thereby, increasing voluntary compliance while reducing compliance 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00024 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335507 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
costs. As a result, PHMSA anticipates 
the amendments contained in this rule will have economic benefits to the regulated community. Executive Order 13563 (‘‘Improving Regulation and Regulatory Review’’) is supplemental to and reaffirms the principles, structures, and definitions governing regulatory review that were established in Executive Order 12866 (‘‘Regulatory Planning and Review’’) of September 30, 1993. In addition, Executive Order 13563 specifically requires agencies to: (1) Involve the public in the regulatory process; (2) promote simplification and harmonization through interagency coordination; (3) identify and consider regulatory approaches that reduce burden and maintain flexibility; (4) ensure the objectivity of any scientific or technological information used to support regulatory action; and (5) consider how to best promote retrospective analysis to modify, streamline, expand, or repeal existing rules that are outmoded, ineffective, insufficient, or excessively burdensome. 
In this final rule, PHMSA has 
involved the public in the regulatory process in a variety of ways: Specifically, PHMSA is addressing issues and errors that were identified for future rulemaking both through letters of interpretation and other correspondence with PHMSA stakeholders who brought editorial errors in the HMR to our attention. In addition, PHMSA has responded to seven petitions for rulemaking and two NTSB Safety Recommendations. PHMSA asked for public comments based on the proposals in this NPRM, and upon receipt of public comment, PHMSA has addressed all substantive comments in this rulemaking action. 
The amendments in the final rule 
promote simplification and harmonization through interagency coordination. In this final rule, PHMSA is revising 49 CFR part 175, in a collaborative effort with the Federal Aviation Administration (FAA), to: clarify the applicability of the HMR to certain aircraft operators, clarify exceptions for passengers and crewmembers, correct inaccurate references to title 14 of the CFR, and make minor editorial corrections applicable to air operations to improve overall clarity. There are minimal additional costs associated with these proposals; however, increased clarity will result in net benefits. 
This final rule also promotes 
harmonization with international standards, such as the IMDG Code, Canada’s TDG requirements, and the ICAO TI. These efforts include: •Harmonizing hazard 
communication for poisonous-by- 
inhalation materials with the IMDG Code and TDG regulations; 
•Removing the packing group II 
designation for certain organic peroxides, self-reactive substances, and explosives to be consistent with the UN Recommendations, IMDG Code, and ICAO TI, thus facilitating international transport; 
•Harmonizing entries in the HMT 
with the above listed international standards; 
•Revising the passenger exceptions 
applicable to small cartridges containing Division 2.2 gas with the ICAO TI; 
•Harmonizing the excepted 
quantities requirements to mirror language employed in the ICAO TI as they apply to articles. 
These revisions to the § 172.101 HMT 
will eliminate errors, reduce ambiguity, 
harmonize the HMR with international regulations, and improve clarity. Although these revisions are minor, they are expected to produce a safety benefit derived from the increased clarity and accuracy of the text in the § 172.101 HMT. 
This final rule permits flexibility in 
achieving compliance when transporting damaged wet electric storage batteries; extends the requalification interval for certain MC 331 cargo tanks in dedicated propane service from five years to ten years for a pressure test and internal visual inspection, therefore, fostering greater regulatory flexibility without compromising transportation safety; clarifies the regulations to provide flexibility in the ability to use the ‘‘NOT-ODORIZED’’ or ‘‘NON- ODORIZED’’ marking on cargo tanks, cylinders, and portable tanks containing odorized or unodorized LPG. Additionally, by allowing 100 pounds of black or smokeless powder for small arms reclassed as Division 4.1 in each transport vehicle, instead of each motor vehicle, the regulated community can reduce the number of motor vehicles needed to transport these goods. 
Where PHMSA identified potential 
costs to stakeholders, specific comment was requested to clarify such costs. We requested and responded to specific comments on potential cost impacts of the proposals in § 172.604. 
A majority of the amendments in this 
rulemaking are simple clarifications and do not require significant scientific or technological information. However, when necessary in this final rule, PHMSA used scientific or technological information to support its regulatory action. Specifically, such data was considered when structuring alternatives on how to best deal with 
issues regarding the testing of pressure relief devices for cargo tank motor vehicles, as well as with issues regarding the extension of the pressure 
test and internal visual inspection test interval from five to ten years for certain MC 331 cargo tanks in dedicated propane delivery service. This information was used in the evaluation of alternative proposals, and ultimately this information determined how best to promote retrospective analysis to modify and streamline existing requirements that are outmoded, ineffective, insufficient, or excessively burdensome. 
C. Executive Order 13132 
This final rule has been analyzed in 
accordance with the principles and 
criteria contained in Executive Order 13132 (‘‘Federalism’’). This final rule would preempt State, local, and Indian tribe requirements but does not propose any regulation that has substantial direct effects on the states, the relationship between the national government and the states, or the distribution of power and responsibilities among the various levels of government. Therefore, the consultation and funding requirements of Executive Order 13132 do not apply. 
The Federal Hazardous Material 
Transportation Law, 49 U.S.C. 5125(b)(1), contains an express preemption provision (49 U.S.C. 5125(b)) preempting State, local, and Indian tribe requirements on certain covered subjects. Covered subjects are as follows: 
(i) The designation, description, and 
classification of hazardous materials; 
(ii) The packing, repacking, handling, 
labeling, marking, and placarding of hazardous materials; 
(iii) The preparation, execution, and 
use of shipping documents related to hazardous materials and requirements related to the number, content, and placement of those documents; 
(iv) The written notification, 
recording, and reporting of the unintentional release in transportation of hazardous materials; 
(v) The design, manufacture, 
fabrication, marking, maintenance, reconditioning, repair, or testing of a packaging or container which is represented, marked, certified, or sold as qualified for use in the transport of hazardous materials. 
This final rule concerns the 
classification, packaging, and handling of hazardous materials, among other covered subjects. If adopted, this rule would preempt any State, local, or Indian tribe requirements concerning 
VerDate Sep<11>2014 19:50 Jun 01, 2016 Jkt 238001 PO 00000 Frm 00025 Fmt 4701 Sfmt 4700 E:\FR\FM\02JNR3.SGM 02JNR3asabaliauskas on DSK3SPTVN1PROD with RULES335508 Federal Register / Vol. 81, No. 106 / Thursday, June 2, 2016 / Rules and Regulations 
these subjects unless the non-Federal 
requirements are ‘‘substantively the same’’ (See 49 CFR 107.202(d) the Federal requirements.) 
The Federal Hazardous Materials 
Transportation Law provides at 49 U.S.C. 5125(b)(2) that if PHMSA issues a regulation concerning any of the covered subjects, PHMSA must determine and publish in the Federal Register the effective date of Federal 
preemption. That effective date may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. The effective date of Federal preemption will be 90 days from publication of a final rule on this matter in the Federal Register. 
D. Executive Order 13175 
This final rule has been analyzed in 
accordance with the principles and 
criteria contained in Executive Order 13175 (‘‘Consultation and Coordination with Indian Tribal Governments’’). Because this final rule does not have tribal implications and does not impose substantial direct compliance costs on 
Indian tribal governments, the funding and consultation requirements of Executive Order 13175 do not apply and a tribal summary impact statement is not required. 
E. Regulatory Flexibility Act, Executive 
Order 13272, and DOT Procedures and Policies 
The Regulatory Flexibility Act (5 
U.S.C. 601 et seq.) requires an agency to review regulations to assess their impact on small entities unless the agency determines the rule is not expected to have a significant impact on a substantial number of small entities. In addition, the Regulatory Flexibility Act directs agencies to establish exceptions and differing compliance standards for small businesses, where it is possible to do so while still meeting the objectives of applicable regulatory statutes. However, in the case of hazardous materials transportation, it is not possible to establish exceptions or differing standards and still accomplish our safety objectives. 
As this final rule would clarify 
provisions based on PHMSA’s initiatives and correspondence with the regulated community, the impact that it will have on small entities is not expected to be significant. The changes are generally intended to provide relief and, as a result, marginal positive economic benefits to shippers, carriers, and packaging manufactures and testers, including small entities. These benefits are not at a level that can be considered economically significant. Consequently, this final rule will not have a significant 
economic impact on a substantial number of small entities. 
This final rule has been developed in 
accordance with Executive Order 13272 (‘‘Proper Consideration of Small Entities in Agency Rulemaking’’) and DOT’s Procedures and Policies to promote compliance with the Regulatory Flexibility Act to ensure that potential impacts of draft rules on small entities are properly considered. 
F. Paperwork Reduction Act 
PHMSA currently has an approved 
information collection under Office of 
Management and Budget (OMB) Control Number 2137–0557, entitled ‘‘Approvals for Hazardous Materials.’’ This final rule does not make any changes that would affect the burden for this or any other information collection. 
Prior to the publication of a final rule 
entitled ‘‘Hazardous Materials: Revisions to Fireworks Regulation’’ published in the Federal Register on 
July 6, 2013 [Docket No. PHMSA–2010– 0320 (HM–257); 78 FR 42457], the HMR contained a requirement that all certification agencies provide a statement confirming that it would perform its functions independent of the owners and manufacturers of the packagings in its field. The burden for this requirement was accounted for under OMB Control Number 2137–0557. However, the HM–257 final rule inadvertently removed this language from the HMR. Therefore, in this final rule, PHMSA is reinserting the language for certification agencies to confirm that they are independent and not owned by a company in its field. For ease of the reader, this language is to be inserted as follows: 
•PHMSA is revising § 107.402(f) to 
require that a portable tank and MEGC certification agency submit a statement indicating that the agency is independent of and not owned by a portable tank or MEGC manufacturer, owner, or distributor as part of the Portable tank and MECG Certification Agency application. 
•PHMSA is revising § 107.402(e) to 
require that a lighter certification agency submit a statement that the agency is independent of and not owned by a lighter manufacturer, distributor, import or export company, or proprietorship as part of the Lighter Certification Agency application. 
•PHMSA is revising § 107.807 to 
require that a person who seeks to manufacture DOT specification cylinders and special permit cylinders, or perform chemical analysis and tests of those cylinders outside the United States submits a statement, as part of the application, indicating that the inspection agency is independent of and not owned by a cylinder manufacturer, owner, or distributor. 
G. Regulation Identifier Number (RIN) 
A regulation identifier number (RIN) 
is assigned to each regulatory action 
listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN number contained in the heading of this document can be used to cross-reference this action with the Unified Agenda. 
H. Unfunded Mandates Reform Act 
This final rule does not impose 
unfunded mandates under the 
Unfunded Mandates Reform Act of 1995. It does not result in costs of $141,300,000 or more to either State, local, or tribal governments, in the aggregate, or to the private sector, and it is the least burdensome alternative that achieves the objective of the rule. 
I. Environmental Assessment 
The National Environmental Policy 
Act of 1969 (NEPA), 42 U.S.C. 4321– 
4375, requires that Federal agencies analyze proposed actions to determine whether the action will have a significant impact on the human environment. In accordance with the Council on Environmental Quality (CEQ) regulations (40 CFR parts 1500– 1508), which implement NEPA, an agency may prepare an Environmental Assessment (EA) when it does not anticipate that the final action will have significant environmental effects. They must consider the following: (1) The need for the proposed action, (2) alternatives to the proposed action, (3) probable environmental impacts of the proposed action and alternatives, and (4) the agencies and persons consulted during the consideration process (40 CFR 1508.9(b)). 
1. Purpose and Need 
The purpose of this final rule is to 
amend the Hazardous Materials 
Regulations (HMR; 49 CFR parts 171– 180) by making miscellaneous revisions to update and clarify certain regulatory requirements, to respond to seven petitions for rulemaking submitted to PHMSA by various stakeholders, and to address two NTSB recommendations. These amendments, which were identified through an internal review of the HMR as well as in response to communications with various stakeholders, are intended to promote safety, regulatory relief, and clarity. This action is necessary in order to: (1) Fulfill

our statutory directive to promote 
transportation safety; (2) fulfill our statutory directive under the Administrative Procedure Act (APA) that requires Federal agencies to give interested persons the right to petition an agency to issue, amend, or repeal a rule (5 U.S.C. 553(e)); (3) support governmental efforts to provide regulatory relief to the regulated community; (4) address safety concerns raised by the NTSB and remove regulatory ambiguity identified by the regulated community; and (5) simplify and clarify the regulations in order to promote understanding and compliance. 
The intended effect of this action is to 
enhance the safe transportation of hazardous materials and, in conjunction, clarify, simplify, and relax certain regulatory requirements for carriers, shippers, and other stakeholders. These regulatory revisions will offer more efficient and effective ways of achieving safe and secure transportation of hazardous materials in commerce. 
2. Alternatives 
The alternatives considered in this 
Environmental Assessment include the 
following: 
Alternative 1: No Action 
Alternative 1 would not result in any 
rulemakings on this subject, leaving the 
current regulatory standards to remain in effect. As a result, this option would not address outstanding petitions for rulemaking or NTSB Safety Recommendations. While this alternative would not impose any new costs or change any environmental impacts, neither would it account for the outstanding petitions for rulemaking, NTSB Safety Recommendations, and regulatory concerns reviewed by PHMSA; thus, we have rejected the no action alternative. 
Alternative 2: Go Forward With the 
Proposed Amendments to the HMR in This NPRM 
Alternative 2 revises the HMR as 
proposed in the NPRM and, accounting for public comment, applies to transportation of hazardous materials by various modes (highway, rail, vessel and aircraft). The amendments encompassed in this alternative are more fully addressed in the preamble and regulatory text sections. However, they generally include the following changes to the HMR, grouped below for ease of discussion:

•Clarify the requirements applicable 
to the testing of pressure relief devices for cargo tank motor vehicles (responds to petition for rulemaking P–1609). 1. Probable Environmental Impacts of the Alternatives 
Hazardous materials are substances 
that may pose a threat to public safety or the environment during transportation because of their physical, chemical, or nuclear properties. Under the HMR, hazardous materials are transported by aircraft, vessel, rail, and highway. The potential for environmental damage or contamination exists when packages of hazardous materials are involved in accidents or en route incidents resulting from cargo shifts, valve failures, package failures, loading, unloading, collisions, handling problems, or deliberate sabotage. The release of hazardous materials can cause the loss of ecological resources (e.g. wildlife habitats) and the contamination of air, aquatic environments, and soil. 
When developing potential regulatory 
requirements, PHMSA evaluates those requirements to consider the environmental impact of each amendment. Specifically, PHMSA evaluates the following: The risk of release of hazmat and resulting environmental impact; the risk to human safety, including any risk to first responders; the longevity of the packaging; and the circumstances in which the regulations would be carried out (i.e., the defined geographic area, 
the resources, any sensitive areas) and how they could thus be impacted. 
PHMSA has determined that most of 
the regulatory changes proposed in this rulemaking are editorial in nature. As such, these amendments have no impact on the risk of release and resulting environmental impact, human safety, longevity of the packaging, and none of these amendments would be carried out in a defined geographic area. General possible environmental benefits, and detriments, are discussed below. 
Alternative 1 
The no-action alternative would result 
in no changes. The current regulations 
would remain in place, and no new provisions would be added. However, this option would not address outstanding petitions for rulemaking, NTSB Safety Recommendations or consider amendments based on PHMSA’s own initiatives intended to update, clarify, or provide relief from certain existing regulatory requirements. Foregone efficiencies in the Alternative 1 also include freeing up limited resources to concentrate on hazardous materials transportation issues of potentially much greater environmental impact. 
Not adopting the proposed 
environmental and safety requirements in the final rule under the Alternative 1 would result in a lost opportunity for reducing environmental and safety- related incidents. 
In addition, greenhouse gas emissions 
would remain the same under the Alternative 1. 
Alternative 2 
If PHMSA selects the provisions as 
amended in this final rule, we believe 
that safety and environmental risks would be reduced and that protections to human health and environmental resources would be increased. 
Alternative 2 will enhance 
environmental protection through more targeted and effective training. This set of amendments will eliminate inconsistent hazardous materials regulations, which hamper compliance training efforts. By maintaining consistency between these international regulations and the HMR, shippers and carriers are able to train their hazardous materials employees in a single set of requirements for classification, packaging, hazard communication, handling, and stowage, thereby minimizing the possibility of improperly preparing and transporting a shipment of hazardous materials because of differences between domestic and international regulations. 
In addition, Alternative 2 will create 
more streamlined hazardous regulations, resulting in compliance training efforts which facilitate the regulated community’s ability to comply with the HMR. Potential environmental impacts of each group of amendments in Alternative 2 (selected for this final rule) are discussed individually below: 
Incorporation by Reference and Use of 
International Standards: 
PHMSA believes that this set of 
amendments, which will increase standardization and consistency of regulations, will result in greater protection of human health and the environment. Consistency between U.S. and international regulations enhances the safety and environmental protection of international hazardous materials transportation through better understanding of the regulations, an increased level of industry compliance, the smooth flow of hazardous materials from origin to destination, and consistent emergency response in the event of a hazardous materials incident. Incorporation of the CGA Publication G– 1.6, Standard for Mobile Acetylene Trailer Systems, will mitigate acetylene release and enhance environmental protection during overturn incidents and unloading.

Current greenhouse gas emissions 
would be unaffected under this 
proposed set of amendments. 
§ 172.101 Hazardous Materials 
Table and § 172.102 Special Provisions: 
PHMSA believes that this set of 
amendments, which will increase standardization and consistency of regulations, will result in greater protection of human health and the environment. As previously stated, consistency between U.S. and international regulations enhances the safety and environmental protection of international hazardous materials transportation through better understanding of the regulations, an increased level of industry compliance, the smooth flow of hazardous materials from their points of origin to their points of destination, and consistent emergency response in the event of a hazardous materials incident. New and revised entries to the HMT reflect emerging technologies and the need to better describe or differentiate between existing entries. These changes mirror those in the Dangerous Goods list of The 18th Revised Edition of the UN Model Regulations, the 2013–2014 ICAO TI and the 37–14 amendments to the IMDG Code. It is extremely important for the domestic HMR to mirror the UN Model Regulations, the ICAO TI, and the IMDG 
Code with respect to the entries in the HMT to ensure consistent naming conventions across modes and international borders. 
The packing group assignment reflects 
a degree of danger associated with a particular material and identifies appropriate packaging. However, assignment of a packing group is not appropriate in all cases (e.g. explosives, 
gases, radioactive material). In such cases the packing group does not indicate a degree of danger, and the packaging requirements for those materials are specified in the appropriate section in part 173. The change to eliminate a packing group designation for materials classified as explosives and organic peroxides specifically listed in the HMT provides a level of consistency, without diminishing environmental protection and safety. 
Current greenhouse gas emissions 
would be unaffected under this set of amendments. 
Hazard Communication (Marking, 
Labeling, Placarding, Emergency Response): 
PHMSA believes that this set of 
amendments, which will provide for enhanced hazard communication (hazcom), will result in greater protection of human health and the environment. The proposed changes 
communicate the nature of various specialized packaging configurations to package handlers and emergency responders. The amendments would ensure that hazard markings are visible, universally recognizable, and that they contain all information needed by emergency responders, thus resulting in fewer incidents with impacts to the environment and safety. 
Similar to the above sets of 
amendments, PHMSA believes consistency between U.S. and international regulations enhances the safety and environmental protection of international hazardous materials transportation through better 
understanding of the regulations, an increased level of industry compliance, the smooth flow of hazardous materials from their points of origin to their points of destination, and consistent emergency response in the event of a hazardous materials incident. 
Current greenhouse gas emissions 
would be unaffected under this proposed set of amendments. 
Shipper Requirements: 
PHMSA believes that this 
amendment, which will revise, clarify 
and enhance current regulations, will result in greater protection of human health and the environment. Shippers and transporters of hazardous materials will more easily be able to comply with the HMR through regulations that are easier to understand and more streamlined. 
Specific to this set of amendments, 
improving the packaging requirements applicable to glass packages of nitric acid reduces the occurrences of fires caused by broken inner containers and enhances human health and environmental protection. PHMSA believes that the additional intermediate packaging required by this particular amendment will add another layer of protection in preventing breakage, leakage, and fires. Additionally, this particular amendment creates a more streamlined and efficient HMR through incorporation of a petition for rulemaking (P–1601), whic allows both regulators and the regulated community to target limited resources at the most pressing hazmat compliance issues. 
Current greenhouse gas emissions 
would be unaffected under this proposed set of amendments. 
Modal Requirements (Air, Vessel, and 
Highway): 
PHMSA believes that this 
amendment, which will revise, clarify, and enhance current regulations, will result in greater protection of human health and the environment. Air, vessel, and highway shippers and transporters of hazardous materials will more easily 
be able to comply with the HMR through regulations that are easier to understand and more streamlined. Additionally, the revisions include emphasis being placed in areas requiring more attention. 
Current greenhouse gas emissions 
would be unaffected under this proposed set of amendments. 
Packaging Design and 
Requalification: 
PHMSA believes that this 
amendment, which will revise, clarify, and enhance current regulations, will result in greater protection of human health and the environment. Shippers and transporters of hazardous materials will more easily be able to comply with the HMR through regulations which are easier to understand and more streamlined. Additionally, the revisions include emphasis being placed in areas requiring more attention. 
Specific to this set of amendments, 
decreasing the required frequency for pressure testing and visual inspection of certain cargo tanks in dedicated propane service by extending the requalification period from five years to ten years will ease the burden on regulators and the regulated community. This test, which requires significant equipment down- time and man-hours to perform, has been shown to achieve no additional safety or environmental protection when performed at a five- versus a ten- 
year interval. In addition, pressure testing requires a significant amount of water usage. Decreasing the testing frequency by half will result in significant volumes of water being conserved. Additionally, this particular amendment creates a more streamlined and efficient HMR through incorporation of a petition for rulemaking (P–1609). A more streamlined and efficient HMR allows both regulators and the regulated community to target limited resources at the most pressing hazmat compliance issues. 
Current greenhouse gas emissions 
would be unaffected under these amendments. 
1. Agencies Consulted 
This final rule would affect some 
PHMSA stakeholders, including 
hazardous materials shippers and carriers by highway, rail, vessel, and aircraft, as well as package manufacturers and testers. PHMSA sought comment on the environmental assessment contained in the NPRM. In addition, PHMSA specifically coordinated with the following Federal agencies and modal partners: 
•Department of Justice

•United States Coast Guard 
2. Conclusion 
PHMSA is adopting miscellaneous 
amendments to the HMR based on 
comments from the regulated community, NTSB recommendations, and PHMSA’s own rulemaking initiatives. The amendments are intended to update, clarify, or provide relief from certain existing regulatory requirements to promote safer transportation practices; eliminate unnecessary regulatory requirements; facilitate international commerce; and make these requirements easier to understand. These clarifications of regulatory requirements will foster a greater level of compliance with the HMR and, thus, diminish levels of hazardous materials transportation incidents affecting the health and safety of the environment. Therefore, the net environmental impact of this proposal will be positive. 
J. Privacy Act 
In accordance with 5 U.S.C. 553(c), 
DOT solicits comments from the public 
to better inform its rulemaking process. The DOT posts these comments, without edit, including any personal information the commenter provides, to www.regulations.gov. The electronic form of these written communications and comments can be searched by the name of the individual submitting the document (or signing the document, if submitted on behalf of an association, business, labor union, etc.). The DOT’s complete Privacy Act Statement is available at http://www.dot.gov/privacy. 
K. International Trade Analysis 
The Trade Agreements Act of 1979 
(Pub. L. 96–39), as amended by the 
Uruguay Round Agreements Act (Pub. L. 103–465), prohibits Federal agencies from establishing any standards or engaging in related activities that create unnecessary obstacles to the foreign commerce of the United States. Pursuant to these Acts, establishing standards is not considered an unnecessary obstacle to the foreign commerce of the United States, so long as the standards have a legitimate domestic objective, such as the protection of safety, and do not operate in a manner that excludes imports that meet this objective. This statute also requires consideration of international standards and, where appropriate, that they be the basis for U.S. standards. PHMSA notes the purpose is to ensure the safety of the American public and has assessed the effects of this rule to ensure that it does not exclude imports that meet this objective. As a result, this final rule is not considered as creating an unnecessary obstacle to foreign commerce.

Note 3: Pressure testing is not required for uninsulated lined cargo tanks, with a design pressure MAWP 15 psig or less, which receive an ex-
ternal visual inspection and lining inspection at least once each year. 
Note 4: Insulated cargo tanks equipped with manholes or inspection openings may perform either an internal visual inspection in conjunc tion 
with the external visual inspection or a hydrostatic or pneumatic pressure-test of the cargo tank. 
Note 5: A 10-year inspection interval period also applies to cargo tanks constructed of NQT SA–202, NQT SA–455, or NQT SA–612 steels 
provided the materials have full-size equivalent (FSE) Charpy vee notch (CVN) energy test data that demonstrated 75% shear-area ductility at 
32°F with an average of 3 or more samples >15 ft-lb FSE with no sample <10 ft-lb FSE.

(j) Pressure vent bench test. When 
required by this section, pressure relief 
valves must be tested for proper function as follows: 
(1) Each self-closing pressure relief 
valve must open and reseat to a leaktight condition at the pressures prescribed for the applicable cargo tank specification or at the following pressures: 
(i) For MC 306 cargo tanks: (A) With MC 306 reclosing pressure 
relief valves, it must open at not less than 3 psi and not more than 4.4 psi and must reseat to a leak tight-condition at no less than 2.7 psi. (B) With reclosing pressure relief 
valves modified as provided in § 180.405(c) to conform with DOT 406 specifications, according to the pressures set forth for a DOT 406 cargo tank in § 178.346–3 of this subchapter. 
(ii) For MC 307 cargo tanks: 
(A) With MC 307 reclosing pressure 
relief valves, it must open at not less 
than the cargo tank MAWP and not more than 110% of the cargo tank MAWP and must reseat to a leak tight- condition at no less than 90% of the cargo tank MAWP. 
(B) With reclosing pressure relief 
valves modified as provided in § 180.405(c) to conform with DOT 407 specifications, according to the pressures set forth for a DOT 407 cargo tank in § 178.347–4 of this subchapter. 
(iii) For MC 312 cargo tanks: 
(A) With MC 312 reclosing pressure 
relief valves, it must open at not less 
than the cargo tank MAWP and not more than 110% of the cargo tank MAWP and must reseat to a leak tight- condition at no less than 90% of the cargo tank MAWP. 
(B) With reclosing pressure relief 
valves modified as provided in § 180.405(c) to conform with DOT 412 specifications, according to the pressures set forth for a DOT 412 cargo tank in § 178.348–4 of this subchapter. 
(iv) For MC 330 or MC 331 cargo 
tanks, it must open at not less than the required set pressure and not more than 110% of the required set pressure and must reseat to a leak-tight condition at no less than 90% of the required set pressure. 
(v) For DOT 400-series cargo tanks, 
according to the pressures set forth for the applicable cargo tank specification in §§ 178.346–3, 178.347–4, and 178.348–4, respectively, of this subchapter. 
(vi) For cargo tanks not specified in 
this paragraph, it must open at not less than the required set pressure and not more than 110% of the required set pressure and must reseat to a leak-tight condition at no less than 90% of the required set pressure or the pressure prescribed for the applicable cargo tank specification. 
(2) Normal vents (1 psig vents) must 
be tested according to the testing criteria established by the valve manufacturer. 
(3) Self-closing pressure relief devices 
not tested or failing the tests in paragraph (j)(1) of this section must be repaired or replaced.
