I. Background

In a final rule published under Docket HM-181 (55 FR 52402, December 21, 1990), the Research and Special Programs Administration (RSPA), the predecessor agency to the Pipeline and Hazardous Materials Safety Administration (PHMSA), comprehensively revised the Hazardous Materials Regulations (HMR; 49 CFR Parts 171 to 180) to harmonize U.S. hazardous materials transportation requirements with the United Nations Recommendations on the Transport of Dangerous Goods (UN Model Regulations). The UN Model Regulations are not regulations, but rather are recommendations issued by the UN Committee of Experts on the Transport of Dangerous Goods (UNSCOE) and the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). These Model Regulations are amended and updated biennially by the UNSCOE and serve as the basis for national, regional, and international modal regulations, including the International Maritime Organization's International Maritime Dangerous Goods Code (IMDG Code) and International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions).

Since publication of the 1990 rule, we have issued eight additional international harmonization rules (Dockets HM-215A (59 FR 67390, December 29, 1994); HM-215B (62 FR 24690, December 16, 1996); HM-215C (63 FR 57929, October 29, 1998); HM-215D (66 FR 8644, February 1, 2001); HM-215E (68 FR 1013, January 8, 2003); HM-215G (69 FR 76044, December 20, 2004); HM-215I (71 FR 78596, December 29, 2006); and HM-215J (74 FR 2200, January 14, 2009)) based on the corresponding biennial updates of the UN Model Regulations, the IMDG Code, and the ICAO Technical Instructions.

To maintain alignment of the HMR with international requirements, in this final rule, we are incorporating changes based on the sixteenth revised edition of the UN Model Regulations, Amendment 35-10 to the IMDG Code, and the 2011-2012 ICAO TI, which becomes effective January 1, 2011 (the IMDG Code is effective January 1, 2012).

Federal law and policy strongly favor the harmonization of domestic and international standards for hazardous materials transportation. The Federal hazardous materials transportation law (Federal hazmat law; 49 U.S.C. 5101 et seq.) permits PHMSA to depart from international standards in order to promote safety or other overriding public interest, but otherwise requires PHMSA to align the HMR with international transport standards and requirements to the extent practicable (see 49 U.S.C. 5120). Harmonization enhances international trade by minimizing the costs and other burdens of complying with multiple or inconsistent safety requirements for transportation of hazardous materials to and from the United States. This becomes increasingly important as the volume of international hazardous materials shipments grows. Harmonization also enhances safety for international movements, but only if the international standards themselves provide an appropriate level of safety. PHMSA actively participates in the development of international standards for the transportation of hazardous materials, frequently advocating the adoption in international standards of particular HMR requirements.

When considering the adoption of international standards under the HMR, we review and evaluate each amendment on its own merit, on the basis of its overall impact on transportation safety, and the economic implications associated with its adoption into the HMR. Our goal is to harmonize without diminishing the level of safety currently provided by the HMR and not impose undue burdens on the regulated public.

II. Primary Topics of Concern Discussed in the ANPRM

PHMSA published an advance notice of proposed rulemaking (ANPRM) (74 FR 53982, October 21, 2009) highlighting issues under consideration for harmonization with international standards and requesting comments as to whether the HMR should be amended to incorporate specific international standards and the potential benefits and costs of doing so.

Comments on specific harmonization issues covered in the ANPRM are discussed in brief below. Please review the notice of proposed rulemaking (NPRM) (75 FR 52070, August 24, 2010) for a complete discussion of comments to the ANPRM.

A. Limited Quantities and Consumer Commodities

PHMSA has long recognized the need to authorize limited exceptions for the transportation of classes and quantities of hazardous materials described as limited quantities, or consumer commodities reclassed as ORM-D. Considerable efforts have been made internationally to harmonize multi-modal standards with regard to the transport of limited quantities, including consumer commodities. PHMSA held public meetings on this issue in February 2006 and March 2008 to discuss potential impacts on domestic stakeholders. Additionally, this issue was discussed during the agency's pre-UN public meetings held in 2006 and 2007. There was considerable domestic interest in pursuing further harmonization internationally due to the potential for substantial savings in transportation costs and improved transportation efficiency. In the ANPRM (74 FR 53982, October 21, 2009), PHMSA invited comments on this issue with regard to aligning the HMR with the UN Model Regulations for the domestic and international transport of limited quantities and consumer commodities. Of particular concern was any potential negative impact on domestic transportation through the elimination of the transportation mechanism for limited quantity hazardous materials reclassed as ORM-D. While some changes adopted in the UN Model Regulations are similar to provisions currently in the HMR (e.g., inner packaging limits and authorized use of non-specification outer packagings), some changes are not (e.g., marking and labeling). In the ANPRM, PHMSA suggested that, depending on comments received and our own evaluation, the agency may determine that the significance of any amendments on this issue may warrant a separate rulemaking action.

We received several comments submitted in response to the ANPRM supporting adoption of the UN Model Regulation limited quantity provisions into the HMR. The commenters urged PHMSA to move forward and adopt the limited quantity provisions as prescribed in the sixteenth revised edition of the UN Model Regulations. However, several commenters expressed concern that this should not be done at the expense of the ORM-D provisions currently in the HMR. Some altogether opposed the elimination of the existing provisions for ORM-D materials as part of HM-215K and recommended that any changes to the requirements be made through a separate rulemaking.

In the NPRM (75 FR 52070, August 24, 2010), PHMSA outlined its determination, partially based on our perception of favorable comments received in response to the ANPRM, that aligning the existing limited quantity provisions in the HMR with the international standards and regulations (i.e., UN Model Regulations, IMDG Code and the ICAO TI) would enhance safety by facilitating a single, uniform system of transporting limited quantity materials. We emphasized the proposals did not include the immediate or short-term removal of the existing provisions in the HMR for limited quantities reclassed as ORM-D (including those for consumer commodities, cartridges, small arms and cartridges, power device) and included a delayed compliance period we believed was sufficient in length to allow stakeholders time to comply with the transition to the revised limited quantity requirements and eventual elimination of the ORM-D classification. Because the limited quantity provisions in the UN Model Regulations and the IMDG Code are closely aligned with those already contained in the HMR, we contended that domestic alignment for highway, rail and vessel transportation would result in minimal impact and regulatory burden. And, because of the inherent risk unique to air transportation, we believed full harmonization with the ICAO TI (where appropriate) was necessary with regard to the materials authorized and quantity limits for limited quantities (including consumer commodities) intended for transport by air.

B. Classification of Division 1.4S Explosives

For eight Division 1.4 explosive articles (UN0323, UN0366, UN0441, UN0445, UN0455, UN0456, UN0460, and UN0500), the UN Model Regulations have been amended to require a Type 6(d) test to determine whether such articles may be assigned to Compatibility Group S. Assignment to Compatibility Group S indicates that hazardous effects from accidental functioning are limited to the extent the article or substance does not significantly hinder or prohibit fire fighting or emergency response efforts in the immediate vicinity of a package containing the material. The test is designed to be performed on a single package containing an explosive article or explosive substance to determine if the package is capable of containing any hazardous effects in the event of an accidental functioning of its contents. The amendment is supplemented by revisions to the explosives testing standards in the UN Manual of Tests and Criteria as well as the adoption of a new special provision that would authorize the use of the above mentioned identification numbers only if the results of the Type 6(d) test successfully demonstrate that any hazardous effects are confined within a package. In the ANPRM, we invited commenters to provide data and information concerning the possible safety impacts of the new test provisions and compliance costs that would be incurred if the new test were adopted into the HMR. In addition, we invited commenters to provide suggestions or recommendations concerning whether to apply the test to already-approved explosives.

We received several comments both supporting and opposing adoption of the Type 6(d) test to determine whether a Division 1.4 explosive article may be assigned to Compatibility Group S. All the commenters who addressed this issue indicated that, if adopted, the test must be applied to previously-approved articles in a manner that is reasonable and not overly broad. One suggestion was to allow the classification of previously-approved explosive articles to be based on results of testing of product groups by a PHMSA-approved laboratory or on results of self-testing and video documentation by the manufacturer.

Commenters opposing adoption of the Type 6(d) test suggested that more research on the practical effect of this testing requirement is necessary and that the lack of grandfathering criteria for products already approved as Division 1.4S explosives (e.g., power device cartridges) is impractical, expensive, and impedes commerce. They also indicated concern regarding the cost of articles consumed in testing in addition to the cost of pre-testing or redesign of an article by a manufacturer to ensure passing the Type 6(d) test, but did not quantify these costs.

C. Classification of Sour Crude Oil

Currently, all types of petroleum crude oil are listed as a Class 3 flammable liquid in the § 172.101 Hazardous Materials Table (HMT). PHMSA is aware that transportation of a certain type of crude oil known as “sour” crude oil may pose risks not associated with other types of crude oil due to its inherent potential of evolving hydrogen sulfide, a highly toxic and flammable gas. Sour crude oil, commonly found in North America, contains a high concentration of sulfur. The evolution of hydrogen sulfide vapors from crude oil is dependent on temperature, packaging confinement, transport conditions (e.g., sloshing), bacteria, and sulfur concentration, among many other potential factors. When transported in bulk packagings such as cargo tanks or tank cars, the evolved hydrogen sulfide gas may build up in the vapor space of the packaging, posing a potential risk, particularly during loading and unloading.

Based on the risk of toxic vapors, the UN Model Regulations were amended by assigning a new identification number and shipping description for sour crude oil with a flammable primary hazard and a toxic subsidiary hazard. Additionally, a new special provision was added specifying the assignment of a Packing Group (PG) based on the degree of danger presented by either the flammability or toxicity hazard of the sour crude oil. For example, sour crude oil meeting flammability criteria for Class 3, PG II, and toxicity criteria for Division 6.1, PG I, poisonous-by-inhalation, would be classified as a Class 3, PG I material.

In the ANPRM, PHMSA invited commenters to provide data and information concerning the impact on domestic shippers and carriers if these requirements were adopted in the HMR. The agency also asked for comments addressing which hazard communication methods (e.g., package markings, shipping papers) and/or packaging requirements are most cost-effective for communicating the hazards and reducing the risks of transporting sour crude oil.

We received comments opposing adoption of the UN amendments for the description and classification of sour crude oil into the HMR. The commenters recommended against requiring domestic use of the new proper shipping name for sour crude oil with a Division 6.1 subsidiary risk and recommended that use be limited to international transport. Commenters further recommended that PHMSA should require drivers engaged in the loading and unloading of sour crude oil to wear a hydrogen sulfide monitoring device and have respiratory protection accessible, and require warning signs at the cargo tank manhole and area of operation. Additionally, commenters recognized that hydrogen sulfide gas is a hazard, but suggested that classification of crude oil at the time of shipment may not reflect the toxicity of hydrogen sulfide in the vapor space of a cargo tank or other packaging after the crude oil has been in transportation. They also noted that there are best industry practices already in place that address this issue and that the Occupational Safety and Health Administration (OSHA) has requirements in place to communicate the hazards of hydrogen sulfide in the workplace. They supported other means of hazard communication to ensure that workers are aware of the hazards of hydrogen sulfide such as a marking on a bulk packaging.

D. IBC Rebottling

Under both the UN Model Regulations and the HMR, replacement of the rigid plastic receptacle of a composite IBC is considered a “repair” under certain conditions and, thus not subject to design qualification testing as a new or different design. The UN Model Regulations were amended to specify that a replacement bottle (i.e., rigid plastic receptacle) must be of the original tested design type and limits the replacement to a bottle from the original manufacturer. In the ANPRM, we invited comments on this amendment and how, if adopted into the HMR, it would impact the use of IBCs in domestic or international commerce.

All commenters who addressed this issue supported the adoption of the UN Model Regulations definition of “repair” for IBC rebottling purposes. The comments included a request for an extended compliance date of January 1, 2012 to provide users and manufacturers of composite IBCs adequate time to implement the provision and not place them at an economic disadvantage with international counterparts.

E. Metal Hydride Storage Systems in Conveyances

A metal hydride storage system is a single complete hydrogen storage system that includes a receptacle, metal hydride, a pressure relief device, a shut-off valve, service equipment, and internal components. The HMR currently do not prescribe specific packaging or shipping methods for metal hydride storage systems containing hydrogen. However, PHMSA has issued a number of special permits to allow the use of these systems for transport. The UN Model Regulations, in new Packing Instruction P205, prescribe standards for the construction, qualification, marking and requalification of such systems. In the ANPRM, PHMSA invited comments on whether similar standards should be adopted into the HMR. One commenter supported adoption of the standards for the construction, qualification, marking, and requalification of metal hydride storage systems containing hydrogen.

F. In Vitro Testing for Corrosivity

In 1993, RSPA began recognizing an alternative test method (i.e., in vitro testing commercially available as Corrositex®), which is not carried out in live animals, to determine the corrosivity of a hazardous material for transportation purposes under the terms and conditions specified in a special permit (DOT-SP 10904). Similar in vitro test methods are prescribed in the following Organization for Economic Cooperation and Development (OECD) Guidelines for the Testing of Chemicals and were adopted in the UN Model Regulations:

• No. 430, “In Vitro Skin Corrosion: Transcutaneous Electrical Resistance Test (TER)” (2004);
• No. 431, “In Vitro Skin Corrosion: Human Skin Model Test” (2004); and,
• No. 435, “In Vitro Membrane Barrier Test Method for Skin Corrosion” (2006).

Because methods 430 and 431 can be used to determine corrosivity for other than transportation purposes, they cannot be used to determine the Packing Group (PG) assignment of a material that tests positive for corrosivity for the purposes of hazardous materials transportation. A negative result for corrosivity under methods 430 and 431 can, however, preclude further testing to determine PG assignment using method 404, the current OECD Guideline involving in vivo testing or method 435, the newly adopted OECD Guideline involving in vitro testing.

All commenters responding to the ANPRM supported adoption and use of the OECD in vitro test methods for determining corrosivity on the basis of reducing the number of tests requiring live animals.

III. Comments Submitted in Response to Noteworthy Harmonization Amendments Proposed in the August 24, 2010 NPRM; the Final Rule

A. Harmonization Amendments Adopted in This Final Rule

In this final rule, PHMSA is adopting the following amendments to harmonize the HMR with the most recent revisions to the UN Model Regulations, ICAO Technical Instructions, and the IMDG Code:

1. Petitions for Rulemaking

We are addressing one petition for rulemaking, P-1550, from PETA requesting that PHMSA incorporate by reference OECD Guidelines 430, 431 and 435 into the HMR that prescribe in vitro testing methods for determining corrosivity.

2. Hazardous Materials Table (HMT)

Amendments to the HMT to add, revise, or remove certain proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, bulk packaging requirements, passenger and cargo aircraft maximum quantity limitations, and vessel stowage provisions.

3. Organic Peroxide Tables

Amendments to the Organic Peroxide Tables to add, revise, or remove certain hazardous materials and provisions.

4. Incorporation by Reference

Amendments to incorporate by reference the 2011-2012 ICAO Technical Instructions, Amendment 35-10 to the IMDG Code, sixteenth revised edition of the UN Model Regulations and the fifth revised edition of the UN Manual of Tests and Criteria. Additionally, we are updating our incorporation by reference of the Canadian Transportation of Dangerous Goods Regulations to include Amendment 6 (SOR/2008-34) February 7, 2008 (pertains to miscellaneous amendments); and Amendment 7 (SOR/2007-179) August 22, 2007 (pertains to highway cargo tanks). This incorporation by reference augments the broad reciprocity provided in § 171.12 where the HMR allow the use of the Canadian TDG Regulations under certain conditions when transporting hazardous materials to or from Canada by highway or rail.

5. Limited Quantities

We received a number of comments in response to the limited quantity and ORM-D classification amendments proposed in the August 2010 NPRM. Commenters can basically be categorized into two groups: Those supporting harmonization with the international standards and regulations for limited quantities and those in opposition to the eventual elimination of the ORM-D classification. The remainder of the commenters offered suggestions or revisions to clarify or aid understanding of the proposed amendments.

Those commenters generally supporting harmonization of the limited quantity provisions include:

Alaska Airlines;

American Coatings Association;

American Trucking Associations;

Association of Hazmat Shipper, Inc.;

Council on Safe Transportation of Hazardous Articles, Inc.;

Dangerous Goods Advisory Council;

FedEx Express;

International Vessel Operators Dangerous Goods Association;

PPG Industries, Inc.;

Sporting Arms and Ammunition Manufacturers Institute, Inc.; and

United Parcel Service.

Those commenters opposing the eventual elimination of the ORM-D hazard classification include:

American Coatings Association;

Aviation Suppliers Association;

Healthcare Distribution Management Association;

Modification and Replacement Parts Association;

PPG Industries, Inc.;

Safety Specialists, Inc.;

Utility Solid Waste Activities Group; and

Valspar.

Due to the large number of commenters and the variety of comments provided, we outline pertinent topic areas to better address all the comments. The comments are discussed and addressed as follows:

a. Air-specific requirements. In the NPRM, we proposed to revise § 173.27 to add a new table outlining air transport requirements for limited quantity material including package quantity limits consistent with the ICAO Technical Instructions. The proposed quantity limits for air transport differ from the quantity limits for other modes, which was a point of contention for some commenters. Three commenters (ACA, DGAC, SSI) disagreed with the adoption of the proposed package limits in the table and one commenter (COSTHA) expressed concern that the table is too broad. ACA asserted:

Introducing these limits will only frustrate domestic transportation and introduce unnecessary complexity into a fairly simple process. In the coatings industry, air shipments are not the norm and are only used when there is some urgency or the destination is a remote location. Requiring different inner and outer packaging quantity limits for air will eliminate the efficiency of a “one size fits all LQ shipments” process.

SSI added:

Some materials that were ORM-D may not be eligible to be shipped as limited quantity. Most inner packagings have been severely reduced. Isopropanol UN1219 (rubbing alcohol) can be presently shipped in inner containers up to 1 liter. Under the new Table 3 the inner container is reduced to 500 milliliter. This product is normally sold in pints, quarts, and gallons. Quarts would not be eligible for limited quantity air shipments. This will require shippers to ship in UN standard packaging, apply hazard class labels and meet all other requirements for fully regulated shipments.

We understand that more inner packagings may be required of a material authorized to be shipped as a limited quantity by air. SSI used Isopropanol as an example in their comments where the inner packaging quantity limits are reduced from 1 liter to 500 milliliters for a Packing Group II Class 3 (flammable liquid) when the current limits of the HMR are compared with the ICAO Technical Instructions. SSI also stated that the product is sold in pints, quarts and gallons. Currently under the HMR, the gallon is ineligible as a limited quantity. Under the amendment proposed in the NPRM, the gallon and quart would be ineligible for air transport as a limited quantity. However, because the outer packaging quantity limit is 1 liter for a Packing Group II Class 3 (flammable liquid), SSI would just have to substitute 2 one-pint inner packagings for a one-quart container of product in the same package.

DGAC reasoned:

The HMR limited quantity provisions predate ICAO TI limited quantity provisions. When limited quantity provisions were introduced in the ICAO TI * * * on the basis of existing U.S. limited quantity provisions, additional limitations were included * * * RSPA and PHMSA have, up until now, not deemed it necessary to incorporate these limitations in the HMR. The long intervening period between when the limits were first introduced in the ICAO TI and the present suggests that it is unnecessary to adopt these limits for the sake of harmonization. Further, [we are] unaware of any new safety information that would justify introducing these limits at this time.

DGAC further argued:

Introducing these limits will serve to frustrate domestic transportation. A key objective of * * * PHMSA has been to provide multimodal harmonization * * * so that the same package will essentially be suitable by all modes of transportation. This is currently true for limited quantity packages * * * By introducing new limits, as shown in the table referenced by proposed § 173.27(f), limited quantity packages prepared for ground or sea transport may not necessarily be suitable for air transport. Most shippers commonly transport * * * limited quantity packages by modes other than air. Currently, with limited quantity package requirements for all modes closely aligned, transporting a limited quantity package is relatively straightforward. If the limitations on inner and outer package quantity limits and new performance requirements are introduced * * * it may be necessary to repackage ground/sea limited quantity packages for purposes of air transport. [We] are unaware of any safety concerns that would justify the imposition of these new limitations.

Major differences already exist under the HMR for the air transport of limited quantities as compared to other modes. For example, limited quantity and consumer commodity inner packagings containing liquids are subject to the pressure differential capability requirements in § 173.27(c).

COSTHA explained further confusion:

It is important for shippers to use the § 172.101 Table to determine eligibility for a limited quantity * * * However, if one uses only Table 3, the shipper may inappropriately determine that a material is eligible for shipment as a limited quantity. For example, [c]hlorosilanes are not permitted to be packaged in accordance with limited quantity provisions * * * however, [certain classes of PG II materials] (many chlorosilanes fall into these classes) are identified as having acceptable limits * * * according to the § 173.27 Table 3. Given that limited quantities is a source of confusion for many shippers and carriers, this table does less to clarify a point and more to confuse the reader.

Section 173.27(f) clearly states that, for transportation by aircraft, materials packaged as limited quantities must be eligible for transportation aboard a passenger-carrying aircraft. In this final rule, we are adding additional clarification in § 173.27(f) to emphasize this critical step in determining limited quantity eligibility by also referring the reader to Column (9A) of the HMT. As stated in the NPRM, PHMSA is studying the feasibility of revising the HMT to further assist in determining limited quantity eligibility by air or possibly by all modes of transportation.

Two commenters (ASA, MARPA) were critical of the nature of proposed regulatory changes without an apparent safety need, specifically with regard to the limited quantity marking for air transport consistent with the ICAO Technical Instructions. The commenters argued that the constant changes make compliance with the regulations difficult. ASA and MARPA stated:

The 2009-2010 [ICAO TI] authorized * * * the UN identification number in a diamond shape [as] the mandatory way to mark limited quantity packages starting in 2011 * * * Beginning in 2011, ICAO has abandoned the marking protocols announced in 2009, and established a new, different identification protocol for identifying limited quantities * * * Instead of placing the UN identification number in the diamond shape, shippers will be required to place a “Y” in the diamond shape * * * There appears to be no reason other than mere harmonization for the sake of harmonization for adopting the ICAO limited quantity marking. [The] marking provides no additional value * * * because many people in the United States system will have no idea what the “Y” marking means * * * Although “Y” is the letter that precedes limited quantity packing instructions in the ICAO system, the letter “Y” has no special meaning in the existing United States Regulations.

b. Dual marking system. Support for harmonization efforts including the adoption of the square-on-point limited quantity marking (i.e., the square-on-point with top and bottom portions black and the center white) generally coincided with support for the eventual elimination of the ORM-D classification along with the ORM-D marking. The basis for support was that this would eliminate a dual system of marking packages for domestic and international transportation. With regard to elimination of a dual marking system, some commenters (AA, FedEx, IVOGDA) indicated that a dual system of marking creates confusion and requires carriers and shippers to adjust their training programs to account for this dual system. They therefore recommend PHMSA consider an earlier implementation date than the proposed January 1, 2013 date. AA added:

We encounter almost every day reused boxes in the U.S. mail, passenger baggage, or cargo shipments that have old ORM-D marks. This takes considerable time to inspect and causes frustration to the public when non-hazardous shipments are denied transportation because of a marking they do not understand as an indication of hazardous materials.

PHMSA notes that adoption of a new limited quantity marking(s) may not necessarily alleviate or eliminate use of packaging premarked with the limited quantity square-on-point for non-hazardous materials.

Notwithstanding the general comments regarding dual marking, several commenters offered suggestions or revisions to improve or clarify the proposed requirements. As part of the NPRM, we authorized voluntary use of the limited quantity marking. UPS urged PHMSA to delay voluntary use to allow carriers time to develop appropriate training in response to a final rule, stating that:

In [our] experience, this kind of authorization * * * can lead to practical difficulties which in turn could have compliance and safety implications * * * Training in UPS will be needed to educate U.S. package handlers of the meaning of the limited quantity marking.

Additionally, on the basis of their opposition to adoption of the air transport requirements for limited quantities consistent with the ICAO TI, DGAC recommended that:

The “Y” package mark [proposed] in § 172.315 not be required * * * [and] recommend that [PHMSA] allow permissive use of the “Y” mark for all modes of transport when the package meets the relevant requirements of the ICAO TI.

We agree with the DGAC recommendation that a “Y” marked package in full conformance with the air transport requirements for a limited quantity package should be authorized transportation by all modes and are revising § 171.22 accordingly. However, we do not agree with their suggestion that the limited quantity “Y” mark be voluntary. There are currently two different ways to mark a package of limited quantities in the HMR and a third (four if counting packaged ORM-D-AIR materials) would be very disruptive. Therefore, in this final rule, PHMSA is adopting the “Y” mark as proposed and providing a transition period to allow for the continued use of existing markings until January 1, 2012.

c. Elimination of the ORM-D class. Most commenters opposing the elimination of the ORM-D classification recommend using a separate rulemaking to implement this proposal. Some question whether the costs of eliminating this classification have been fully considered; others question whether there is sufficient safety justification to warrant replacing the current domestic ORM-D provisions with internationally harmonized provisions. A sampling of comments received follows. ACA argued:

Although [we] supported harmonization of the limited quantities exceptions at the UN discussions, [there was an] understanding that the consumer commodity exception was a separate issue * * * In the coatings and adhesives industry, we are unaware of any major incidents with consumer commodity shipments. While PHMSA indicates that “aligning the existing limited quantity provisions in the HMR with the international standards will substantially enhance safety,” we question how this applies to the proposal to eliminate ORM-D consumer commodities.

Valspar asserted:

We believe PHMSA has overreached the HM-215 harmonization process by proposing * * * to eliminate the well-defined ORM-D (Consumer Commodity) hazard class. We believe any proposal * * * should not be linked to the international harmonization program. In several industry/regulatory conferences it has been proposed that Limited Quantity and Consumer Commodity are synonymous. We do not agree with this premise and strive to ensure that our “Consumer Commodities” meet the spirit and HMR definition of “* * * intended or suitable for sale through retail sales agencies or instrumentalities for consumption by individuals for purposes of personal care or household use.” [We ship] many items under Limited Quantity provisions that we do not believe meet the “suitability” test and assert there is an important distinction between the two. We applaud PHMSA for clearly defining the pathway to ORM-D through Limited Quantity and Special Provision options and can only imagine whether this can be misused through other less clear regulation * * * We challenge PHMSA to revisit the assertion to Executive Order 12866 cited in the HM-215K NPRM that only considers the listed harmonization to be beneficial, with no acknowledgement of the financial cost to ORM-D shippers.

DGAC expressed concern that:

Eliminating the ORM-D classification and package marking [will make it] that such packages will no longer be excepted from the § 175.75 requirements for air transport. No similar requirement applies under the ICAO TI so * * * this change cannot be justified on the basis of harmonization * * * [We believe] PHMSA considers limited quantity packages and currently classified ORM-D packages as posing comparable hazard[s]. Consistent with that approach, we recommend that PHMSA similarly except all limited quantity packages from the § 175.75 requirements.

We agree with DGAC regarding § 175.75 quantity limits for limited quantity packages and are revising the section accordingly. Limited quantity shipments will enjoy the same exception from the § 175.75 quantity limits as ORM-D-AIR materials currently receive.

USWAG stated:

We believe elimination of the ORM-D standards for transportation * * * will disrupt longstanding shipping practices while failing to provide commensurate safety benefits.

The commenter also expressed concern for downstream shippers who have received ORM-D packages but can no longer transport this package beginning on the January 1, 2014 proposed compliance date. USWAG encouraged PHMSA to implement a phased-in approach that would authorize downstream shippers (that do not repackage these materials) to use ORM-D provisions for an additional period of time.

One commenter (HDMA) provided information that the proposal as written would impose significant cost on the domestic transport of medicines and other healthcare or consumer products. HDMA members concluded that compliance with the regulations would require replacement of more than 10 million plastic totes embossed with the ORM-D marking, costing members an estimated $70 million to purchase new totes with the new limited quantity marking. HDMA is prepared to phase out the use of totes with the ORM-D marking but believes this should be done over an extended period of time to enable existing totes embossed with the marking to be used over their lifetime. HDMA stated:

PHMSA may not have recognized that some industries rely on containers that are embossed with the transport mark and hence conversion to a new mark is considerably more complicated than simply changing a label.

Just as PHMSA has done in the past, if there is merit to a particular segment of the regulated community requiring a longer transition period to be considered, it shall be observed on a case-by-case basis. In their comments, HDMA did not indicate what a “normal” lifetime would be. In their defense, however, they provided comments that were quantified and directly related to their concerns about the regulatory and economic burden placed upon their particular industry.

Finally, several commenters (e.g., COSTHA, FedEx) noted concern over use of the ORM-D mark after the transition period ends (i.e., beginning January 1, 2014). The commenters recommend that PHMSA clarify that at the end of the transition period, a package marked with the ORM-D mark will no longer indicate that a packaging contains a hazardous material (i.e., a consumer commodity).

d. Conclusion. In the August 2010 NPRM, PHMSA outlined our determination, partially based on our perception of favorable comments received in response to the ANPRM, that aligning the existing limited quantity provisions in the HMR with the international standards and regulations (i.e., UN Model Regulations, IMDG Code and the ICAO TI) would enhance safety by facilitating a single, uniform system of transporting limited quantity materials. We emphasized the proposals did not include the immediate or short-term removal of the existing provisions in the HMR for limited quantities reclassed as ORM-D (including those for consumer commodities, cartridges, small arms and cartridges, power device) and included a delayed compliance period we believed was sufficient in length to allow stakeholders time to comply with the transition to the revised limited quantity requirements and eventual elimination of the ORM-D classification.

Based on careful consideration of the comments received in response to the proposals made in the NPRM, PHMSA is moving forward with a substantially revised final rule that adopts the new limited quantity provisions and the eventual phase-out of the ORM-D hazard class. This will implement a standardized system for national and international multimodal transportation. The approach of deminimis quantities, excepted quantities, limited quantities and consumer commodities will all have the same provisions and requirements for international and national transportation in a system that will promote compliance, efficiency and consistent training and lower costs after implementation.

6. Classification of Certain Division 1.4S Explosives

In the August 24, 2010 NPRM, PHMSA stated it understood commenter concerns that prescribing additional tests usually results in increased research and development costs. PHMSA also acknowledged that it believed there was merit to additional prescribed tests when they result in a credible and measureable increase in safety. Consequently, in the NPRM we proposed to require the phased-in testing of all new and previously approved Division 1.4S explosives articles and substances, depending on the intended mode of transport. For newly produced explosive articles, a person who successfully performs the Type 6(d) test would not be required to also perform the Type 6(a) test. PHMSA believes such initiatives will greatly reduce research and development costs without compromising safety.

In the NPRM, PHMSA proposed to adopt the requirement for the Type 6(d) test as prescribed in Section 16.7 of the fifth revised edition of the UN Manual of Tests and Criteria in the new § 172.102(c)(1), special provision 347. For affected articles (or substances) intended for transportation by aircraft, the proposed compliance date of this new requirement was April 1, 2011. If a manufacturer or approval holder of affected articles that previously classed and approved an article as Division 1.4S chooses to continue offering such shipments by aircraft, we proposed the articles must be successfully tested under Test Series 6(d) and a new approval be obtained from PHMSA. Additionally, we proposed that a previously classed and approved Division 1.4S article that is not successfully tested under Test Series 6(d) must be assigned to a compatibility group other than “S” (e.g., B, C, or D) prior to the April 1, 2011 compliance date if intended for transportation by aircraft on or after that date. PHMSA also proposed that the effective date of testing to maintain Division 1.4S classification or reassignment to a higher compatibility group other than “S” be no later than January 1, 2014 for Division 1.4S articles approved prior to January 1, 2012 and are intended for domestic highway or rail transportation. For previously-approved affected articles transported by highway, rail and vessel, reassignment to a compatibility group other than “S” may be accomplished by using existing data and, when recommended by an authorized examination and testing agency, approved by PHMSA. For international highway, rail and vessel transportation, the effective date of Type 6(d) testing requirements or reassignment for new and previously produced affected articles would be January 1, 2012 (i.e., the compliance date of a final rule under this docket, if adopted as proposed).

A number of commenters (Baker, EBAD, ESD, IME, Infotrac, NNSA, OCS, SAAMI, and Titan) addressed our proposal to adopt the Type 6(d) test and associated requirements. Several commenters expressed support for comments submitted by IME and requested that PHMSA give consideration to their comments. Thus, our response to comments will primarily be structured based on the comments IME submitted.

a. Compliance dates (i) Air transport. IME expressed concern that the proposed compliance date for Type 6(d) testing to determine Division 1.4S classification for materials to be transported by air precedes the compliance date for the rulemaking in general. IME stated:

The “compliance date of a final rule under this docket” will be January 1, 2012. Simultaneously, however, the proposal establishes a compliance date for transportation by aircraft of April 1, 2011. Accordingly, the compliance date for an individual mode regulated under the rule would precede the compliance date for the rule itself, rendering the April 1, 2011 compliance date both unreasonable and unenforceable.

We disagree. As general policy, PHMSA implements a one-year transition period for international harmonization rulemakings. Thus, we typically publish a rulemaking under the HM-215 docket to be effective January 1 of a given year (to coincide with international effective dates) and require compliance one year later to afford stakeholders the opportunity to prepare for compliance. PHMSA is not bound to the one year transition period and has discretion to institute an earlier compliance date when circumstances warrant. The implementation of this requirement was viewed to be significant by the ICAO Dangerous Goods Panel and an emergency addendum was requested from the Air Navigation Commission. Preventing the transportation of an explosive article with the ability to exit its packaging that could result in collateral damage on a passenger aircraft was determined to be an immediate safety concern and was implemented on very short notice for international air transportation. Therefore, because of concern for the safety in transport of these articles by air and to affect a transition for international air transport with minimal disharmony in compliance dates (the Type 6(d) test is required under ICAO Technical Instructions as of January 1, 2011), we proposed to implement the April 1, 2011, compliance date for Type 6(d) testing for transport by aircraft.

IME also expressed concern that the proposed compliance date of April 1, 2011 for air transport is unattainable. IME stated further:

[T]hat PHMSA's internal policy establishes a 120-day review period for processing approvals * * *. [W]e have determined that in order to meet the April 1, 2011 compliance deadline for air transportation, approval applicants planning to continue shipping by air would have to ensure that all required testing is completed and the results submitted to PHMSA by December 2, 2010. The required testing must be performed or witnessed by “an authorized examination and testing agency approved by PHMSA.” On average, the lead time required to schedule testing with a PHMSA-approved laboratory is six weeks. An additional two weeks would then be required for testing the laboratory to perform the required tests and generate a report * * *. Accordingly, applicants intending to meet the April 1, 2011 deadline would have [had to] finalize arrangements with the testing laboratories by October 4, 2010—twenty-one days prior to the close of the public comment period * * *. Given the impossibility of timely compliance, the proposed April 1, 2011 date will function not as a compliance deadline, but as an automatic prohibition on [of] air transport of the affected 1.4S articles.

PHMSA acknowledges the strict compliance timeline proposed for the air transport of affected articles and substances. We note, however, that the PHMSA imposed 120-day period for processing of approvals is not a minimum time period but general guidance for estimating the time period to review and process an approval application dependent on multiple factors such as the complexity of an application or errors in its submittal. The approval process may take less than 120 days and routinely does. Additionally, PHMSA's Approvals and Permits Division recently streamlined the explosive approval process to accommodate an influx of approval requests based on adoption of Type 6(d) test prescribed in this rulemaking. Finally, shippers are not constrained to the use of domestic laboratories approved by PHMSA but may utilize the resources of laboratories under the umbrella of other competent authorities (e.g., Transport Canada). However, given the strict timeline proposed in the August 2010 NPRM, the significant number of approval applications we expect to receive, and the potential for delays at authorized testing laboratories attempting to accommodate the volume of testing or reclassification requests, we are extending the compliance date for air transport to July 1, 2011.

(ii) Vessel transport. IME noted our failure to indicate a compliance date for domestic vessel transportation. We agree. Our intent was to implement a compliance date that coincides with the effective date of the IMDG Code requirement for the Type 6(d) test (January 1, 2012). Therefore in this final rule, we will require the Type 6(d) test for Division 1.4S classification beginning January 1, 2012 for both domestic and international vessel transportation.

(iii) Modal variability. IME expressed concern that the varying compliance dates for air transport (proposed April 1, 2011), international highway, rail, and vessel (domestic and international) (proposed January 1, 2012), and domestic highway and rail (proposed January 1, 2014) will result in confusion and unintentional noncompliance with specific regard to downstream customers. IME reasoned:

The customer has no way of knowing that the manufacturer ships only domestically [by highway] and has not, therefore, reclassified the product to meet the earlier compliance date for international transport. This leads to unintentional noncompliance by the downstream customer * * *. We recommend that PHMSA promulgate a single compliance date for all modes and for domestic and international transportation.

We disagree. Unawareness of a requirement cannot be used as a defense for non-compliance. Downstream customers or shippers may utilize a number of resources to determine whether an explosive article or substance subject to the Type 6(d) test has been successfully tested. For example, they can obtain a copy of the approval issued by PHMSA. Additionally, it is the shipper's responsibility to properly class and describe a material (see § 173.22) and to be trained on any applicable requirements (see § 172.704) of the HMR. That said, the Approvals and Permits Division will issue guidance to all current approval holders for affected Division 1.4S articles and materials to provide detailed instruction on the new requirement for Type 6(d) testing. This will include issuing new or amended approvals indicating whether a Type 6(d) test has been successfully conducted which can then be used by downstream customers and shippers to aid in transport decision-making.

b. Testing requirements. (i) Self-testing. In response to the ANPRM, IME recommended allowing self-testing and video documentation for articles previously approved as Division 1.4S. IME continued to assert that testing requirements for previously approved articles not be overly broad and questioned why this recommendation was not addressed even though PHMSA specifically acknowledged IME's comments in the NPRM. IME reiterated:

Providing manufacturers with the option to self-test is an effective means of ensuring reasonable application of the new test. Additionally, allowing self-testing of already approved explosives articles will assist industry in minimizing the financial impact of implementation of a new test on already approved, safely transported, explosives.

We disagree. PHMSA believes a uniform process for testing using the Type 6(d) test to determine Division 1.4S classification is the best approach and we do not believe incorporating variability into the process by allowing self-testing and video-documentation for already approved articles complements this approach. PHMSA understands the need to facilitate any possible cost reduction regarding the application of this new testing requirement. We also maintain, however, that in the interest of uniform safety standards under the HMR, requiring that testing be observed or conducted by a PHMSA-approved laboratory is the best approach. This approach will not be codified in the HMR but rather will be incorporated into the explosives approval process as specified in § 173.56 of the HMR.

(ii) Clarification of NPRM preamble. Certain phrases and terms were used in the August 2010, NPRM which have caused confusion. We would like to clarify. Regarding the phrase “incremental testing,” use of the phrase refers to the staggered compliance dates depending on the mode of transport or domestic/international transport and does not indicate differences in reclassification testing. We are removing any reference to this phrase in the preamble to this final rule to avoid further confusion. Regarding the term “design,” as in “previously approved designs,” the term was meant to signify individual explosives articles or substances. We are also deleting any use of this term in the preamble to this final rule to avoid any ambiguity in the use of the term.

(iii) Modal difference. In response to our proposed implementation of the new testing requirement for Division 1.4S classification, IME objected to any varying testing criteria tied to the intended mode of transport, stating:

Such action is not consistent with the UN classification system; additionally, an explosive's reaction to stimuli is not affected by the mode of transport. PHMSA offers no rationale for excluding the use of existing test data for the reclassification of articles intended for air transport, and the distinction would inevitably result in confusion and unintended noncompliance in the regulated community.

We agree that there should be uniform testing criteria across all modes. We apologize for the lack of clarity in implementation of this new testing requirement and will clarify further in the following section (c) discussion of our implementation of the Type 6(d) test.

(iv) Laboratory recommendation. For previously approved articles, we proposed to allow reassignment to a compatibility group other than “S” using existing data and when recommended by a PHMSA-approved laboratory. IME did not support the proposal to require a recommendation from a PHMSA-approved laboratory where a previously approved article is being reassigned. IME argued:

Inability to successfully pass the new Type 6(d) test does not invalidate the original laboratory tests and recommendation[s] that were previously sufficient to attain 1.4S classification. Accordingly, there is no rational basis for requiring a laboratory recommendation to support a downgrade in classification. A laboratory recommendation should only be required where the original classification is not supported by laboratory testing and a corresponding recommendation * * * [W]e are also concerned that if the proposal is promulgated as drafted, some testing laboratories may be reticent to issue the required recommendation solely on the basis of existing test data, and may require new testing.

We appreciate the concerns presented by IME. Again, we apologize for any lack of clarity in implementing this new provision. As indicated previously, our Approvals and Permits Division will be issuing guidance and instruction on testing or reclassification of previously approved Division 1.4S articles or substances. As part of that instruction and in order to alleviate any potential problems from laboratories being reticent to provide a recommendation based on existing data, the Approvals and Permits Division will be providing guidelines to laboratories for which types or batches of already approved articles and substances should be reclassed into which type of downgraded compatibility group.

c. Implementation of the Type 6(d) test in the explosives approval process. As IME accurately summarized in its comments, there are three categories of explosive articles or substances affected by the test requirement: (1) Previously approved Division 1.4S articles that will pass the Type 6(d) test; (2) previously approved Division 1.4S articles that will not pass the Type 6(d) test and therefore need to be reassigned to a more conservative compatibility group other than “S”; and (3) new explosive articles for which Division 1.4S classification must be determined through successful Type 6(d) testing. All explosive articles affected by the Type 6(d) test requirement fit into these three categories regardless of the mode of transport. The compliance date for affected articles is dependent upon the intended mode of transport and whether they are to be transported domestically or internationally. Beginning January 1, 2012, any new explosive articles must be successfully subjected to the Type 6(d) test to determine whether Division 1.4S classification is appropriate. However, for a new explosive material intended for transport by aircraft, the compliance date for successful Type 6(d) testing is no later than July 1, 2011. For existing approved Division 1.4S articles intended for transport by air, successful Type 6(d) testing is also required no later than July 1, 2011; otherwise, the articles must be reassigned to another compatibility group and a new approval issued by PHMSA prior to being offered for transportation or transported by aircraft. Beginning January 1, 2012, existing approved Division 1.4S articles intended for international transport by highway, rail, or vessel and for domestic transport by vessel, successful Type 6(d) testing is required; otherwise, the articles must be reassigned to another compatibility group and a new approval issued by PHMSA prior to being offered for transportation. Finally, for existing approved Division 1.4S articles intended for domestic transportation by highway or rail, successful testing or compatibility group reassignment is required beginning January 1, 2014.

We realize the intended mode of transport may change as markets change and evolve but staggered compliance dates we believe are necessary in order to provide sufficient time to manufacturers, shippers, PHMSA-approved laboratories, and our Approvals and Permits Division to accommodate the number of approved Division 1.4S articles that will need testing or reclassification as well as attempting to allay some of the costs to manufacturers who only transport by domestic highway or rail.

d. Federal considerations. Two commenters (ESB, NNSA) within the Department of Defense and Department of Energy, respectively, objected to the Type 6(d) test requirement for previously approved Division 1.4S explosive material based on cost and logistical concerns. NNSA noted:

[M]ore significant than the added costs, are the limited testing assets available necessary to complete testing by the prescribed deadline in the NPRM. [We do not] recognize the need to conduct UN Test Series 6(d) testing on all future permanent hazard classification requests as specified in the NPRM.

ESB added:

[We object to] with applying the test Type 6(d) for articles previously classified. DOD has been assigning classifications using a methodology that includes assessing projections, fireballs, and jets of flame from unconfined initiation testing. DOD would consider this methodology as equivalent testing and criteria for the assignments of the eight Divisions 1.4 explosive [a]rticles. The DOD [has] not noted any transportation issues with the 378 articles assigned these UN numbers * * * Conducting test Type 6(d) for the 378 articles would take a considerable amount of time without any credible or measurable increase in safety * * * Reclassifying * * * by reassigning CGs other than S is also not a viable option due to the complexity of DOD logistics. Consolidating, and remarking each shipping container located at strategic positions around the world for [defense purposes] would be costly, time consuming and potentially have little safety improvements.

ESB recommended adding a grandfathered exception or issuing a special permit for previously approved DOD Division 1.4S material. We acknowledge concerns by Federal agencies regarding costs and time constraints in the interest of national security. We are currently working directly with potentially affected government stakeholders to remedy concerns regarding implementation of the new requirement for the Type 6(d) test on such entities.

7. Classification of Sour Crude Oil

PHMSA agreed with comments submitted in response to the October 2009 ANPRM that a new proper shipping name is not necessary and that there are more appropriate ways to communicate the potential inhalation hazard risk to transport workers. Therefore, in the August 2010 NPRM, PHMSA proposed to adopt the new proper shipping name found in the UN Model Regulations—“Petroleum sour crude oil, flammable, toxic”—with the letter “I” in Column (1) of the HMT indicating that this description is appropriate for use during international transportation. However, PHMSA did not propose to require use of the new proper shipping name for domestic transportation. PHMSA did propose that a new marking be applied to bulk packagings containing sour crude oil to communicate the potential inhalation risk in transportation.

Three commenters (API, ATA, DGAC) opposed our proposed requirements as ill-conceived and impractical and had concerns with the new marking. They believe the new marking is not necessary based on industry best practices already in place. One commenter (AAR) sought clarification of rail carrier requirements in relation to the proposed marking requirement. Although the commenters opposed our proposed requirements, they strongly support hazard communication processes and procedures to protect employees, the public and the environment from any unreasonable risk of danger from hydrogen sulfide gas. API noted:

Cargo specific testing of individual packages upon loading, followed by the required identification, classification, packaging selection, marks, labels, placards, and documentation process is impractical. The physical and chemical criteria of the DG/HazMat define the basic shipping information * * * The preparation of shipping information and selection of packagings is typically done well in advance of loading on the basis of known, reliably measured, physical and chemical criteria of the materials being transported. When a wide range of the test results is possible, the DG/HazMat classifiers generally utilize the most conservative data to develop the basic shipping information * * * It is impossible to predict the concentration of H2S in the head space vapors evolving from liquid petroleum crude oils. There is not [a] standardized test, statistical correlation, or known methodology to do this * * * Without a reliable, proven methodology, any attempt to develop a classification process regarding potential, future H2S vapor space concentrations is unrealistic * * * API could support the use of a differentiated graphic, unique in communicating the potential H2S vapor [but any] such mark should be considered voluntary and not mandated * * *. Companies should be allowed the flexibility in choosing an option that works best for their operations.

DGAC added:

[W]e are concerned that providing a warning for select crude oils may result in decreased vigilance when other substances also posing a potential hydrogen sulfide risk are handled * * *. If * * * PHMSA maintains that a mark is still necessary, we recommend that the applicability of any marking be limited to cargo tank truck operations * * * PHMSA should allow the warning to appear in the vicinity of the loading/unloading operation or on the vehicle at the loading location. This would avoid the need to add and remove the mark from the cargo tank truck * * * We consider the proposed GHS poison mark to be inappropriate * * * Applying the PHMSA proposed mark on crude oil tanks that do not meet the inhalation toxicity criteria results in a hazard communication conflict which should and can be avoided * * *. Should PHMSA maintain a warning is needed, we recommend a warning sign in English that conveys the message that there is a potential hydrogen sulfide hazard. An example could be * * * “Danger, Possible Hydrogen Sulfide Inhalation Hazard,” * * * [to be possibly] supplemented by pictograms.

ATA expressed concerns that:

Not every load of sour crude will form hydrogen sulfide during transportation, which will require carriers to repeatedly affix and remove markings * * * If carriers are required to repeatedly alter marking requirements, issues of employee safety from climbing on top of tank trucks as well as economic issues * * * must be better understood. [We] recommend that the warning be located at the loading or unloading facility rather than on the tank truck or other bulk container.

We agree in part with the comments. We continue to maintain that there is a safety risk to hazmat employees that may become exposed to hydrogen sulfide vapor in proximity to openings on packagings during a loading or unloading operation due to elevated concentrations of hydrogen sulfide vapors. We do not believe this risk is limited to cargo tank motor vehicles. It may be that the primary mode of transportation for petroleum crude oil is by cargo tank motor vehicle, but we also continue to maintain that any proposed requirement should apply to all bulk packagings as we believe this risk may be present in any packaging with a bulk quantity of petroleum crude oil.

PHMSA agrees with commenters who have stated that a hazard warning statement specific to hydrogen sulfide gas on bulk packagings would provide for appropriate communication of the risk of potential exposure to such gas. PHMSA notes that such a marking is both specific to the gas and aligns with corresponding warnings currently employed in practice on the shipping documentation. Therefore, in this final rule, PHMSA is amending the marking requirement originally proposed to provide more flexibility to shippers and carriers by allowing a text warning such as “Danger, Possible Hydrogen Sulfide Inhalation Hazard” on bulk packagings containing sour crude to communicate the potential inhalation risk in transportation. See Section 172.327 for a discussion of the new marking requirements.

8. IBC Rebottling

In the NPRM, PHMSA proposed to adopt the revised definition of “repair” for composite IBCs consistent with international standards. To specifically address commenters' concerns, PHMSA noted that any proposed compliance date would be no earlier than January 1, 2012, thus providing ample time to comply with the new IBC requirement. We did not receive any additional comments in response to the NPRM. Therefore, in this final rule we are adopting the revised definition of “repair” of an IBC as proposed. See Section 180.350 for a discussion of the revised requirement.

9. Metal Hydride Storage Systems in Conveyances

In the August 2010 NPRM, PHMSA proposed to adopt the standards for the construction, qualification, marking and requalification of hydrogen in metal hydride storage systems adopted in the UN Model Regulations. We did not receive any additional comments in response to the NPRM. Therefore, in this final rule we are adopting the requirements as proposed. See Section 173.311 for a discussion of requirements for hydrogen in a metal hydride storage system.

10. In Vitro Testing for Corrosivity

Based on the overwhelming support for adoption into the HMR, in the NPRM PHMSA proposed to adopt and authorize the use of the OECD in vitro methods. We received over 2,200 comments additional to that received from PETA, in response to the NPRM supporting the adoption of in vitro testing methods to determine corrosivity and urging PHMSA to stop the requirement for use of methods based on live animal testing. Therefore, in this final rule we are adopting the OECD in vitro testing methods as proposed. See Section 173.137 for further discussion of such methods.

B. Harmonization Amendments Not Considered for Adoption in This Final Rule

This final rule makes changes to the HMR based on amendments made in the UN Model Regulations (sixteenth revised edition), IMDG Code (Amendment 35-10) and the ICAO Technical Instructions (2011-2012), which becomes effective January 1, 2011 (the IMDG Code is effective January 1, 2012). We are not, however, adopting all the amendments made to the various international standards into the HMR. In many cases, we have not adopted amendments to the international recommendations and regulations because the framework or structure of the HMR makes adoption unnecessary. In other cases, we have handled, or will be handling, the amendments in separate rulemaking proceedings.

One of the goals of this rulemaking is to continue to maintain consistency between the HMR and the international requirements. We are not striving to make the HMR identical to the international regulations, but rather to remove or avoid potential barriers to international transportation.

Below is a listing of those significant amendments to the international regulations that we are not adopting in this final rule, with a brief explanation of why the amendment was not included:

1. Requirements for Radioactive Materials

In the NPRM, we did not propose to adopt provisions pertaining to the transportation of Class 7 (radioactive) materials into the HMR. Amendments to requirements pertaining to the transportation of Class 7 (radioactive) materials are based on changes contained in the International Atomic Energy Agency (IAEA) publication, “IAEA Safety Standards: Regulations for the Safe Transport of Radioactive Materials.” Due to their complexity, these changes are being addressed in a separate rulemaking.

2. Requirements for Lithium Batteries

PHMSA published an NPRM under Docket HM-224F (75 FR 1302, January 11, 2010) that proposed to adopt provisions to ensure all lithium batteries are packaged properly to reduce the possibility of damage to lithium batteries that could lead to a catastrophic incident, and to minimize the consequences of an incident should one occur. In addition, PHMSA proposed to require lithium battery shipments to be accompanied by hazard communication that ensures appropriate and careful handling by air carrier personnel, including the flight crew, and informs both transport workers and emergency response personnel of actions to be taken in an emergency. The NPRM, which PHMSA developed in close coordination with our colleagues in the Federal Aviation Administration, is the latest in a series of actions PHMSA has taken to address the very serious risks posed by lithium batteries in transportation. The NPRM included proposed revisions to the HMR that were based on lithium battery provisions in the sixteenth revised edition of the UN Model Regulations. Therefore, except for wheelchairs powered by lithium ion batteries, we are not adopting new provisions pertaining to the transportation of lithium cells and batteries in this rulemaking. The docket for the lithium battery rulemaking can be found elsewhere at http://www.regulations.gov under PHMSA-2009-0095.

We note that a number of commenters objected to our inclusion of limitations on the stowage of lithium batteries in § 175.75 of the HMR and strongly urged that the limitations be removed from this rulemaking and addressed in a separate lithium battery rulemaking such as HM-224F. We agree. All reference to lithium batteries in our revisions to § 175.75 are removed from this rulemaking.

3. Requirements for Air Packaging

We are not adopting provisions pertaining to certain packagings offered for transportation by aircraft under this rulemaking. PHMSA is considering certain amendments to the HMR related to requirements for the packaging of hazardous materials intended for transportation by aircraft under a separate docket (HM-231A). These would include amendments based on the reformatted packing instructions in the 2011-2012 ICAO Technical Instructions. PHMSA published an ANPRM (73 FR 38361, July 7, 2008) and an NPRM (75 FR 27273, May 14, 2010) related to combination packaging standards offered in air transportation. See http://www.regulations.gov under PHMSA-2007-29364 for more information.

IV. Section-by-Section Review

Following is a section-by-section review of the amendments in this final rule:

Part 171

Section 171.7

The “National Technology Transfer and Advancement Act of 1996” directs agencies to use voluntary consensus standards. According to the Office of Management and Budget (OMB) Circular A-119, “Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities,” government agencies must use voluntary consensus standards wherever practical in the development of regulations. Agency adoption of industry standards promotes productivity and efficiency in government and industry, expands opportunities for international trade, conserves resources, improves health and safety, and protects the environment.

To these ends, PHMSA actively participates in the development and updating of consensus standards through representation on more than 20 consensus standard bodies. PHMSA regularly reviews updated consensus standards and considers their merit for inclusion in the HMR.

Section 171.7 lists all materials incorporated by reference (IBR materials) into the HMR. For this rulemaking, we evaluated updated international consensus standards and regulations pertaining to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements and determined that the revised standards provide an enhanced level of safety without imposing significant compliance burdens. These materials have a well-established and documented safety history. Their adoption maintains the high safety standard currently achieved under the HMR.

Some commenters (IATA, PRBA, Saft) indicated concern that the fifth revised edition of the UN Recommendations on the Transportation of Dangerous Goods, Manual of Tests and Criteria (UN Manual) was not included among the IBR materials to be updated and suggest that PHMSA include the document.

We agree. PHMSA proposed to incorporate by reference the fifth revised edition of the UN Manual under docket HM-224F published January 11, 2010 (75 FR 1302) because the revised version of the manual contained updated tests for lithium cells and batteries. However, that rulemaking will have an effective date later than this final rule. This rule contains provisions regarding new test requirements for other materials (e.g., explosives) that are found in the updated edition of the UN Manual making it necessary for us to incorporate by reference the fifth edition. Therefore, we are including the updated fifth revised edition of the UN Manual and updating the IBR materials referenced in the HMR by adding and revising material under the following organizations:

Section 171.8

This section defines terms generally used throughout the HMR that have broad or multi-modal applicability. We received no comments regarding our proposed adoption of new definitions. Therefore, in this final rule PHMSA is adding the following defined terms based on their adoption in the UN Model Regulations:

Metal hydride storage system. This term means a single complete hydrogen storage system that includes a receptacle, metal hydride, pressure relief device, shut-off valve, service equipment and internal components used for the transportation of hydrogen only.

Open cryogenic receptacle. This term means a transportable thermally insulated receptacle for refrigerated liquefied gases maintained at atmospheric pressure by continuous venting of the refrigerated gas.

Additionally, we proposed to revise the definition of Oxidizing gas to specify that an oxidizing gas is a pure gas or gas mixture with an oxidizing power greater than 23.5% as determined by a method specified in ISO 10156:1996 or 10156-2:2005. See also Sections 172.101 and 173.115, for discussion of changes to the “Compressed gas, n.o.s., UN1956.” HMT entry and definition, respectively. We received no comments on the revised definition. Therefore, in this final rule we are adopting the revision as proposed.

Section 171.23

Section 171.23 prescribes the conditional requirements for specific materials and packages transported under the various international standards as permitted by the HMR. In this final rule we are removing the § 171.23(b)(9) requirement that stipulates Division 6.1 poisonous materials transported as limited quantities are not excepted from labeling. This change aligns the labeling requirements in the HMR for limited quantities with the international standards without compromising safety.

Section 171.25

Section 171.25 prescribes the additional requirements for specific materials and packages transported under the IMDG Code as permitted by the HMR. In this final rule, we are deleting paragraphs (c)(5) and (d)(3). Paragraphs (c)(5) and (d)(3) required portable tanks, cargo tanks, and tank cars containing cryogenic liquids transported by vessel to be stowed on deck regardless of the stowage requirements authorized under the IMDG Code. The IMDG Code now requires this same stowage for certain packagings containing cryogenic materials aboard a vessel, thus, paragraphs (c)(5) and (d)(3) are no longer necessary.

Effective January 1, 1997, vehicles and mechanical equipment containing internal combustion engines were no longer subject to the IMDG Code as conditionally designated under Amendment 28-96. Effective January 1, 2012, such articles will once again be subject to the IMDG Code under Amendment 35-10. Because the new requirements in the IMDG Code are more stringent than requirements for similar material in the HMR, PHMSA is amending § 171.25 by revising paragraph (b)(1) and adding a new paragraph (b)(4) permitting use of the IMDG Code or the HMR to prepare and stow vehicles and mechanical equipment containing internal combustion engines when offered for transport by vessel.

Part 172

Section 172.101

Introductory text to the § 172.101 HMT contains explanatory text for each of the columns that comprise the HMT. Currently, § 172.101(c)(10) provides specific requirements regarding the selection of an appropriate proper shipping name for mixtures and solutions containing more than one hazardous material of the same hazard class. In many cases, such mixtures and solutions are best described by a generic or “not otherwise specified” entry (i.e., an “n.o.s.” entry). For example, a solution containing two or more flammable liquid constituents may best be described under the entry “Flammable liquids, n.o.s., UN1993.” However, in some cases where two or more hazardous materials are present, a single hazardous material may predominate where the other hazardous materials may be present in only trace amounts. In such cases, a description applicable to the predominant material may be more appropriate. A recent incident underscores the importance of using the most specific and appropriate shipping description. In that incident, an aluminum cylinder containing 99.9% pure ethyl chloride ruptured in storage incidental to transport. It was determined that the root cause was a reaction between the cylinder's contents and the aluminum. The relevant construction standard for the cylinder indicated that ethyl chloride was reactive with aluminum and that aluminum was not recommended for the transport of ethyl chloride. However, the shipper selected a generic compressed gas shipping description rather than the ethyl chloride name due to the presence of trace amounts of other hazardous materials. While we note that the general requirements for packagings still broadly address the responsibility of the shipper in selecting a packaging that is compatible with its lading, and that these requirements were also applicable and apparently overlooked, the incident nonetheless highlights the benefit of using a more specific description, where appropriate, to help ensure that the most appropriate transport provisions are followed.

To address this issue, the UN Model Regulations were amended to require, except as otherwise specified, that a mixture or solution of a single predominant hazardous material containing only traces of one or more additional hazardous materials listed by name in the HMT or additional non-hazardous constituents be assigned the UN number and proper shipping name of the predominant material contributing to the overall hazard classification of the mixture or solution. Adopting a similar provision in the HMR will enhance a shipper's ability to select the most appropriate shipping description. In the NPRM, PHMSA proposed to add a new paragraph, § 172.101(c)(10)(iv), outlining the authorization to describe the mixture or solution based on the predominant material contributing to the hazard classification.

One commenter (DOE) suggested that we remove the reference to non-hazardous material in § 172.101(c)(10)(iv) because the mixture of hazardous material and non-hazardous material is already addressed in § 172.101(c)(10)(i). Additionally, the commenter asked for clarification of instances when the provision should be used and asked to define the meaning of “trace amounts.”

We agree. It is correct that § 172.101(c)(10)(i) already addresses a mixture or solution of a hazardous material and non-hazardous material. The provision pertains to a mixture or solution containing non-hazardous material in such quantities that it does not alter the physical state or purity of the hazardous material it is mixed with, as well as either the hazard classification, packing group, subsidiary hazard, or emergency response procedures. The intent of new paragraph § 172.101(c)(10)(iv) is to provide instruction for selecting the most appropriate proper shipping name for a mixture or solution of a hazardous material and traces of one or more other hazardous materials, one or more non-hazardous materials, or both. Where such a mixture or solution occurs that the trace amount of material does not affect the classification, the material must be described using the most appropriate proper shipping name for the predominant hazardous material. Based on the comment received and reconsideration of our proposal, we are instead revising paragraph (c)(10)(i) to provide clarification on properly describing a material that is a mixture or solution of a predominant hazardous material and trace amounts of hazardous or non-hazardous material, or both; rather than add a new paragraph (c)(10)(iv). The six conditions in § 172.101(c)(10)(i) that currently limit a mixture or solution of hazardous material with a non-hazardous material from being described using the proper shipping name of the hazardous material would also apply to a mixture or solution of a single predominant hazardous material and trace amounts of other hazardous or non-hazardous materials or both.

With regard to instances when the provision would be used, we would expect it to be applied in cases of mixtures or solutions of a hazardous material that contain small amounts of preservatives or are contaminated with trace amounts of hazardous material in such a way that the “trace amounts” do not affect the packaging, the hazard class, the packing group, etc of the hazardous material. As for defining “trace amounts” we do not specifically define this term because determination of when an amount of material affects the hazard classification is highly variable depending on the physical and chemical properties of the materials involved and the quantities of material involved. Therefore, in this final rule, we are revising § 172.101(c)(10)(i) to provide instruction on properly describing a material that is a mixture or solution of a predominant hazardous material and trace amounts of hazardous or non-hazardous material, or both.

Paragraph (e) of § 172.101 provides explanations for the letters that precede identification numbers assigned to proper shipping names in the HMT. In this final rule, PHMSA is adding an explanation for identification numbers associated with certain descriptions under the ICAO Technical Instructions and are preceded by the letters “ID.” Additionally, PHMSA is authorizing use of the international air description, “ID8000, Consumer commodity, 9” in the HMT with material and article eligibility for use of the description based on Special provision A112 and Packing Instruction Y963 of the 2011-2012 ICAO Technical Instructions.

Hazardous Materials Table (HMT)

In this final rule, PHMSA is making various amendments to the HMT. Readers should review all changes for a complete understanding of the amendments. For purposes of the Government Printing Office's typesetting procedures, changes to the HMT appear under three sections of the Table, “remove,” “add,” and “revise.” Certain entries in the HMT, such as those with revisions to the proper shipping names, appear as a “remove” and “add.” Amendments to the HMT include the following:

New HMT entries

UN3482	Alkali metal dispersions, flammable or Alkaline earth metal dispersions, flammable.
UN3496	Batteries, nickel-metal hydride.

This new HMT entry for UN3496 includes a W in Column (1) to indicate use of this hazardous materials description is limited to vessel transport of these materials.

Two commenters (Saft, PRBA) indicated concern with our proposed assignment of Special Provision 130 (for transportation of dry batteries—i.e., “Batteries, dry, sealed, n.o.s.”) to this entry and the potential for confusion leading to use of this entry for modes other than vessel.

We agree. To help clarify the use of this entry, we have included additional language in Column (2) to refer shippers transporting nickel-metal hydride batteries by modes other than vessel to the HMT entry “Batteries, dry, sealed, n.o.s.” for instruction on the transport requirements for nickel-metal hydride batteries. Additionally, we have revised Special Provision 130 to make clear that for other than nickel-metal hydride batteries transported by vessel subject to Special Provision 340, dry batteries must be transported in accordance with Special Provision 130.

UN3485	Calcium hypochlorite, dry, corrosive or Calcium hypochlorite mixtures, dry, corrosive with more than 39% available chlorine (8.8% available oxygen).
UN3487	Calcium hypochlorite, hydrated, corrosive or Calcium hypochlorite, hydrated mixture, corrosive with not less than 5.5% but not more than 16% water.
UN3486	Calcium hypochlorite mixture, dry, corrosive with more than 10% but not more than 39% available chlorine.
ID8000	Consumer commodity.

This shipping description is added to the HMT as a Class 9 miscellaneous hazardous material to be used for the air transportation of limited quantities of certain hazardous materials of Class 2 (non-toxic aerosols only), Class 3 (PG II and III only), Division 6.1 (PG III only), and of UN identification numbers UN3077, UN3082, and UN3175, provided such materials do not have a subsidiary risk and are authorized aboard a passenger-carrying aircraft. This amendment is based on changes incorporated into the 2011-2012 ICAO TI.

UN3484	Hydrazine aqueous solution, flammable with more than 37% hydrazine, by mass.
UN3495	Iodine.

Iodine is transported globally under a number of different shipping descriptions dependent on the shipper. In the interest of reducing risks associated with transport of iodine under various descriptions and therefore, various packaging, we are adding this unique UN identification number and shipping description to provide for specific packaging requirements and faster identification and access to emergency response information.

UN1471	Lithium hypochlorite, dry or Lithium hypochlorite mixture, Division 5.1, PG III.

Lithium hypochlorite is a common commercial product used as a disinfectant that is often mixed with other non-hazardous organic salts. Currently, the HMT only provides for a Division 5.1, PG II designation for this material, yet testing conducted in accordance with the UN Manual of Tests and Criteria has indicated that some common commercial mixtures meet the criteria for classification in Division 5.1, PG III. Therefore, PHMSA is adding a line to the current entry to allow for classification of lithium hypochlorite and mixtures of lithium hypochlorite in PG III, where appropriate.

One commenter (FMC) noted that the addition of the proposed PG III entry for the “Lithium hypochlorite, UN1471” shipping description retains the italicized text “with more than 39% available chlorine (8.8% available oxygen)” as well as the word “dry” for lithium hypochlorite mixtures and that this is not consistent with the hazardous materials description in the dangerous goods list in the UN Model Regulations, the ICAO Technical Instructions, and the soon to be adopted IMDG Code. FMC requested that PHMSA revise the entry by deleting the qualifying text as well as the word “dry” to be consistent with international standards and regulations and to provide shippers with the most appropriate shipping description for the transport of lithium hypochlorite materials. Additionally, FMC stated:

[M]ore fundamental and practical problems will arise if this qualifying text is retained in the HMR entry for UN1471. Some of the commercial lithium hypochlorite products shipped domestically and internationally by FMC have less than 39% available chlorine (8.8% available oxygen), and so would not be properly described by the entry as it is proposed to be modified. [T]hese products nevertheless meet the criteria for classification in Division 5.1, Packing Group II or III. Consequently, under the HMR, FMC must describe these products by an appropriate entry in the HMT associated with the correct class and packing group, namely “Hypochlorites, inorganic, n.o.s.” (UN3212) if the product meets Packing Group II criteria, or, since UN3212 does not provide a Packing Group III option, “Oxidizing solid, n.o.s.” (UN1479) if the product meets the criteria for assignment to Packing Group III. Thus, for road and rail transport within the United States FMC's lithium hypochlorite products would have to be described by one of three different entries.

We agree. Removing the italicized text would facilitate a uniform process of describing lithium hypochlorite materials for transport purposes without reducing the safety of transport when using this description in lieu the descriptions discussed in the comment by FMC. Additionally, we are making a conforming amendment (with the IMDG Code) to the PG II entry for UN1471 to assign special provisions T3 and TP33 applicable to a portable tank when used to transport this material. T3 outlines the minimum test pressure, minimum shell thickness, bottom opening requirements, and pressure relief requirements in addition to the design and constructions requirements for the portable tank. TP33 outlines provisions for transport of granular or powdered solids. Therefore, in this final rule, we are adopting the PG III entry for “Lithium hypochlorite, UN1471” without the italicized text and the word “dry,” as well as making a conforming revision to the shipping description for the PG II entry already in the HMT to read, “Lithium hypochlorite, dry or Lithium hypochlorite mixtures, UN1471.”

UN3483	Motor fuel anti-knock mixture, flammable.
UN3494	Petroleum sour crude oil, flammable, toxic (this entry is identified in the HMT as appropriate for international transportation under § 172.101(b)(5)).
UN3492	Toxic-by-inhalation liquid, corrosive, flammable, n.o.s. with an inhalation toxicity lower than or equal to 200 ml/m 3 and saturated vapor concentration greater than or equal to 500 LC 50.
UN3493	Toxic-by-inhalation liquid, corrosive, flammable, n.o.s. with an inhalation toxicity lower than or equal to 1000 ml/m 3 and saturated vapor concentration greater than or equal to 10 LC 50.
UN3488	Toxic-by-inhalation liquid, flammable, corrosive, n.o.s. with an inhalation toxicity lower than or equal to 200 ml/m 3 and saturated vapor concentration greater than or equal to 500 LC 50.
UN3489	Toxic-by-inhalation liquid, flammable, corrosive, n.o.s. with an inhalation toxicity lower than or equal to 1000 ml/m 3 and saturated vapor concentration greater than or equal to 10 LC 50.
UN3490	Toxic-by-inhalation liquid, water-reactive, flammable, n.o.s. with an inhalation toxicity lower than or equal to 200 ml/m 3 and saturated vapor concentration greater than or equal to 500 LC 50.
UN3491	Toxic-by-inhalation liquid, water-reactive, flammable, n.o.s. with an inhalation toxicity lower than or equal to 1000 ml/m 3 and saturated vapor concentration greater than or equal to 10 LC 50.

Based on a recommendation by a commenter (PPG), we note that two new entries for toxic-by-inhalation (TIH) material (i.e., UN3492 and UN3493) added in the sixteenth revised edition of the UN Model Regulations and in this final rule will likely be removed from the dangerous goods table in the seventeenth revised edition of the UN Model Regulations. Shippers who choose to use these new descriptions on shipping papers and markings on boxes may incur additional costs when having to change the material descriptions again should the descriptions be removed from the UN Model Regulations and subsequently, the HMR.

Additionally, because of the addition of generic TIH descriptions for toxic, flammable, corrosive material (i.e., UN 3488, UN3499), PPG believes the domestic entries for “sec-Butyl chloroformate, NA2742” and “Isobutyl chloroformate, NA2742” are obsolete and recommended that these materials be described using the generic TIH descriptions for consistent hazard communication of these materials between modes of transportation.

We agree. Therefore, in this final rule, as a conforming amendment to the addition of the generic TIH entries, we are deleting the domestic use entries “sec-Butyl chloroformate, NA2742” and “Isobutyl chloroformate, NA2742” from the HMT.

Amendments to the Column (1) Symbols

The entries “Elevated temperature liquid, flammable, n.o.s., with flash point above 37.8 °C, at or above its flash point, UN3256,” “Elevated temperature liquid, n.o.s., at or above 100 °C and below its flash point (including molten metals, molten salts, etc.), UN3257,” and “Elevated temperature solid, n.o.s., at or above 240 °C, UN3258” are revised by adding the symbol G. The symbol G identifies proper shipping names for which a technical name of the hazardous material is required in parentheses in association with the basic description. Requiring the technical name(s) for certain elevated temperatures materials will help emergency responders in selecting the proper materials for extinguishing a fire involving these hazardous materials and will aid in estimating the temperature properties of the materials (e.g., the melting point).

The entries “Metal catalyst, dry, UN2881” and “Metal catalyst, wetted with a visible excess of liquid, UN1378” are revised by adding the symbol G. The symbol G identifies proper shipping names for which a technical name of the hazardous material is required in parentheses in association with the basic description. Requiring the technical name(s) for metal catalysts will aid emergency responders in selecting the proper fire suppressant (e.g., CO₂) if the hazardous material is involved in a fire or in identifying other materials the metal catalyst could react with.

The entry “Powder, smokeless, UN0509,” is revised by deleting the symbol D. The symbol D identifies a proper shipping name for domestic use only. This entry has been adopted into the UN Model Regulations, the ICAO TI, and the IMDG Code. This deletion is consistent with our final rule published under Docket HM-215J (74 FR 2200, January 14, 2009) in which we indicated our intent to remove the symbol D in a future rulemaking upon adoption of the entry into international regulations.

For the following Division 5.1 (oxidizer) materials and Division 6.1 (toxic) materials, the entries are revised by adding the symbol G. The symbol G identifies proper shipping names for which one or more technical names of the hazardous material must be entered in parentheses in association with the basic description on a shipping paper. Knowledge of the technical name of toxic materials may aid emergency responders with implementing more appropriate first aid measures:

UN3141	Antimony compounds, inorganic, liquid, n.o.s.
UN1549	Antimony compounds, inorganic, solid, n.o.s.

UN1566	Beryllium compounds, n.o.s.
UN3213	Bromates, inorganic, aqueous solution, n.o.s.
UN1450	Bromates, inorganic, n.o.s.
UN2570	Cadmium compounds.
UN3210	Chlorates, inorganic, aqueous solution, n.o.s.

UN2025	Mercury compounds, solid, n.o.s.
UN3144	Nicotine compounds, liquid, n.o.s. or Nicotine preparations, liquid, n.o.s.
UN1665	Nicotine compounds, solid, n.o.s. or Nicotine preparations, solid, n.o.s.
UN3219	Nitrites, inorganic, aqueous solution, n.o.s.
UN2627	Nitrites, inorganic, n.o.s.
UN3214	Permanganates, inorganic, aqueous solution, n.o.s.
UN1482	Permanganates, inorganic, n.o.s.
UN2026	Phenylmercuric compounds, n.o.s.
UN2630	Selenates or Selenites.
UN3440	Selenium compound, liquid, n.o.s.
UN3283	Selenium compound, solid, n.o.s.
UN3284	Tellurium compound, solid, n.o.s.
UN3285	Vanadium compound, solid, n.o.s.

Amendments to the Column (2) Hazardous Materials Descriptions and Proper Shipping Names

The proper shipping name for the entry “Detonator, assemblies, non-electric, for blasting, UN0500,” is revised by removing the comma after “Detonator” to read “Detonator assemblies, non-electric, for blasting.” This revision appears as a “Remove/Add” in this rulemaking.

The proper shipping name for the entry “Engines, internal combustion, flammable gas powered, UN3166,” is revised to read “Engines, internal combustion or Engines, fuel cell, flammable gas powered.” This revision appears as a “Remove/Add” in this rulemaking.

One commenter (IATA) suggests that we revise this proper shipping name to the singular “engine” in alignment with use of the singular form for the entries in the UN Model Regulations. We disagree. As indicated by the commenter, § 172.101(c)(1) authorizes use of proper shipping names in the singular or plural form. Therefore, we believe it is not necessary to revise the proper shipping name to the singular “engine” when the shipper is authorized to modify the proper shipping name between singular and plural forms.

The proper shipping name for the entry “Engines, internal combustion, flammable liquid powered, UN3166,” is revised to read “Engines, internal combustion or Engines, fuel cell, flammable liquid powered.” This revision appears as a “Remove/Add” in this rulemaking.

One commenter (IATA) suggests that we revise this proper shipping name to the singular “engine” in alignment with use of the singular form for the entries in the UN Model Regulations. We disagree. As indicated by the commenter, § 172.101(c)(1) authorizes use of proper shipping names in the singular or plural form. Therefore, we believe it is not necessary to revise the proper shipping name to the singular “engine.”

The proper shipping names “Formaldehyde, solutions, flammable, UN1198” and “Formaldehyde, solutions, with not less than 25 percent formaldehyde, UN2209” are revised to remove an errant comma between the words “Formaldehyde” and “solutions.” This revision appears as a “Remove/Add” in this rulemaking.

The proper shipping name for the entry “1-Hydroxybenzotriazole, anhydrous, wetted with not less than 20 percent water, by mass, UN3474” is revised to read “1-Hydroxybenzotriazole, monohydrate.” This revision appears as a “Remove/Add” in this rulemaking.

The proper shipping name for the PG II entry for Lithium hypochlorite, dry with more than 39% available chlorine (8.8% available oxygen) or Lithium hypochlorite mixture, dry with more than 39% available chlorine (8.8% available oxygen), UN1471” is revised to read “Lithium hypochlorite, dry or Lithium hypochlorite mixture” to conform with the addition of the new PG III entry and international use of this proper shipping name. This revision appears as a “Remove/Add” in this rulemaking.

The proper shipping name for the entry “Nitric acid other than red fuming, with less than 65 percent nitric acid, UN2031” is revised to read “Nitric acid other than red fuming, with more than 20 percent and less than 65 percent nitric acid, UN2031.” The proper shipping name for the Packing Group I entry “Nitric acid other than red fuming, with more than 70 percent nitric acid, UN2031” is added to the HMT. In a final rule published on January 14, 2009 (HM-215J; 74 FR 2200), errors were made to both nitric acid entries and in this final rule, PHMSA aligns them correctly in accordance with the various international standards. Additionally, we are removing the outdated Packing Group II entry “Nitric acid other than red fuming, with not more than 70 percent nitric acid, UN2031” that should have been removed from the HMT in the same final rule.

The proper shipping name for the entry “Tars, liquid including road asphalt and oils, bitumen and cut backs, UN1999” is revised to read “Tars, liquid including road oils and cutback bitumens.” The entries in the HMT applicable to transport of bitumen may cause confusion with respect to the proper classification of the material. The entries include “Combustible liquid, n.o.s., NA1993, combustible liquid” and “Tars, liquid including road asphalt and oils, bitumen and cut backs, UN1999, 3,” and the entries “Elevated temperature liquid, flammable, n.o.s., UN3256, 3” and “Elevated temperature liquid, n.o.s., UN3257, 9,” when the material is heated and offered for transport. Bitumen is a hydrocarbon material derived from crude oil having a flashpoint of 160 °C or greater. Bitumens typically do not meet the classification for a Class 3 flammable liquid except for cutback bitumens which are blended with a flammable material such as kerosene. Also, road asphalt is bitumen mixed with sand and fillers which also does not meet the classification for a Class 3 flammable liquid. Therefore, we are revising the proper shipping name “Tars, liquid including road asphalt and oils, bitumen and cut backs” by removing reference to asphalt and clarifying applicability to cutback bitumens to read “Tars, liquid including road oils and cutback bitumens.” This revision appears as a “Remove/Add” in this rulemaking.

The proper shipping name for the entry “Trinitro-meta-cresol, UN0216” is revised to read “Trinitro-m-cresol.” This revision appears as a “Remove/Add” in this rulemaking.

The proper shipping name for the entry “Vehicle, flammable gas powered, UN3166,” is revised to read “Vehicle, flammable gas powered or Vehicle, fuel cell, flammable gas powered.” This revision appears as a “Remove/Add” in this rulemaking.

The proper shipping name for the entry “Vehicle, flammable liquid powered, UN3166,” is revised to read “Vehicle, flammable liquid powered or Vehicle, fuel cell, flammable liquid powered.” This revision appears as a “Remove/Add” in this rulemaking.

Amendments to the Column (3) Hazard Class or Division

PHMSA is revising the classification of a number of entries to Division 6.1 poisonous primary hazards for consistency with the adoption of classification changes into the sixteenth revised edition of the UN Model Regulations. The changes are based on data provided from a thorough review of literature on toxic-by-inhalation materials. The review of literature is provided in Informal Document UN/SCETDG/33/INF.8 submitted to the 33rd session of the UN Sub-Committee of Experts on the Transport of Dangerous Goods which is available at http://www.unece.org/​trans/​main/​dgdb/​dgsubc/​c3inf33.html.

For the entry “Tetranitromethane, UN1510,” the Class 5 (oxidizer) material's primary hazard is revised to a Division 6.1 (poisonous) material primary hazard.

For the following Class 3 (flammable liquid) materials, the Class 3 primary hazard is revised to a Division 6.1 (poisonous) material primary hazard.

UN2481	Ethyl isocyanate.
UN2486	Isobutyl isocyanate.
UN2483	Isopropyl isocyanate.
UN3079	Methacrylonitrile, stabilized.
UN2605	Methoxymethyl isocyanate.

For the following Class 8 (corrosive) materials, the Class 8 primary hazard is revised to a Division 6.1 (poisonous) material primary hazard.

UN1810	Phosphorous oxychloride.
UN1834	Sulfur chloride.
UN1838	Titanium tetrachloride.

Amendments to the Column (5) Packing Group (PG)

The entry “Carbon dioxide, solid or Dry ice, UN1845” is revised by deleting the PG III designation. In general, the PG assigned to a material identifies the degree of hazard the material represents and determines the performance level of the packaging required for the material. For example, a PG II material (i.e., a moderate hazard material) is considered more hazardous and requires more stringent packaging than a PG III material (i.e., a low hazard material). Dry ice presents minimal risk during transport except where concentrations may build up in a confined space. Therefore, in this final rule, PHMSA is deleting the PG III designation from the entry.

For the following Division 6.1 poisonous materials, the PG is revised to read PG I.

UN2668	Chloroacetonitrile.
UN1810	Phosphorous oxychloride.
UN2474	Thiophosgene.
UN1838	Titanium tetrachloride.

PHMSA is making this revision to the PG assignment for these entries for consistency with the adoption of changes into the sixteenth revised edition of the UN Model Regulations. The changes are based on data provided from a thorough review of literature on toxic-by-inhalation materials. The review of literature is provided in Informal Document UN/SCETDG/33/INF.8 submitted to the 33rd session of the UN Sub-Committee of Experts on the Transport of Dangerous Goods which is available at http://www.unece.org/​trans/​main/​dgdb/​dgsubc/​c3inf33.html.

Amendments to the Column (6) Label(s)

For the following hazardous material entries, PHMSA is revising the label requirements for consistency with changes made to the classification of these materials under amendments to Column (3) (see above). The Class 3 (flammable liquid), Class 8 (corrosive), or Division 5.1 (oxidizer) primary hazard labels, as appropriate, and the Division 6.1 (poisonous) subsidiary hazard label are revised to a Division 6.1 (poisonous) material primary hazard label and Class 3, Class 8, or Division 5.1 subsidiary hazard label to read “6.1, 3,” “6.1, 8,” or “6.1, 5.1,” as appropriate.

UN2481	Ethyl isocyanate.
UN2486	Isobutyl isocyanate.
UN2483	Isopropyl isocyanate.
UN3079	Methacrylonitrile, stabilized.
UN2605	Methoxymethyl isocyanate.
UN1810	Phosphorous oxychloride.
UN1834	Sulfur chloride.
UN1838	Titanium tetrachloride.

The entry “Chlorosilanes, toxic, corrosive, flammable, n.o.s., UN3362” is revised by correctly ordering the sequence of labeling hazards to reflect the proper shipping name to read “6.1, 8, 3.”

Amendments to the Column (7) Special Provisions

The entry “Chloropicrin, UN1580” is revised by replacing the portable tank instruction T Code T14 with T22. The UN Committee of Experts on the Transport of Dangerous Goods revised the T Code assignment for a number of Division 6.1 (toxic-by-inhalation) materials from T14 to T22. Assigning T22 requires a higher pressure for the periodic hydrostatic test (6 bar to 10 bar) and a thicker minimum shell thickness (6 mm to 10 mm). Therefore, for consistency with revisions made to the T Code assignments under the sixteenth revised edition of the UN Model Regulations, we are revising the T Code to read T22.

The entry “Compressed gas, n.o.s., UN1956” is revised by deleting special provision 77 which authorizes the use of this entry for mixtures of gases with less than 23.5% oxygen when no other oxidizing gases are present. Because we are modifying the definition of oxidizing gas in § 171.8 of the HMR to indicate that “a gas which may, by providing oxygen, cause or contribute to the combustion of other material more than air does means pure gases or gas mixtures with an oxidizing power greater than 23.5% oxygen” and because the entry “Compressed gas, oxidizing, n.o.s., UN3156” is currently available in the HMT, the special provision is redundant and no longer necessary.

The entry “Environmentally hazardous substance, solid, UN3077” is revised by adding new special provision A112 authorizing the transportation of certain IBCs containing this material up to a maximum net quantity of 1,000 kg by passenger or cargo-only aircraft.

The entry “Ethylene oxide or Ethylene oxide with nitrogen up to a total pressure of 1 MPa (10 bar) at 50 degrees C, UN1040 is revised by deleting special provision A59 and adding new special provision 342. The provisions in A59 applied only to air transport but they now apply to all modes under new Special provision 342. See Section 172.102 special provisions for a discussion of new special provision 342.

The entry “1-Hydroxybenzotriazole, monohydrate, UN3474” is revised by deleting special provision 162. Special provision 162 requires that for the material to be transported as a Division 4.1 desensitized material, it must be transported in such a manner that at no time during the course of transportation does the percentage concentration of water fall below 20%. Anhydrous hydroxybenzotriazole rapidly converts to the monohydrate form in the presence of water, that is, the thermally stable form of the substance. Additionally, tests have indicated that the monohydrate maintains its water content under temperature conditions encountered in storage and transport over extended periods of time. This conforms to the intent of the provisions specified in special provision 162 and therefore, we are deleting special provision 162 from the entry.

The entry “Motor fuel anti-knock mixtures, UN1649” is revised by deleting special provision 151. Special provision 151 requires that if this material also meets the definition of a Class 3 (flammable) liquid under § 173.120 of the HMR, a FLAMMABLE LIQUID label is required and the basic description on the shipping paper must indicate the Class 3 subsidiary hazard. However, because of the addition of the new entry “Motor fuel anti-knock mixtures, flammable, UN3483” which indicates a Class 3 subsidiary hazard, we believe it is no longer necessary to assign special provision 151 to this entry.

The entry “Nitrogen, refrigerated liquid cryogenic liquid, UN1977” is revised by adding new special provisions 345 and 346. See Section 172.102 special provisions for a discussion of new special provisions 345 and 346.

The entry “Oxygen, compressed, UN1072” is revised by adding special provision 110 authorizing an actuating cartridge (e.g., power device cartridges of Division 1.4, compatibility groups C and S) to be installed on a cylinder containing oxygen without changing the classification of Division 2.2. See Section 172.102 special provisions for a discussion of our revision to special provision 110.

The entry “Pentaerythrite tetranitrate or Pentaerythritol tetranitrate or PETN, with not less than 7 percent wax by mass, 0411)” is revised by assigning special provision 120 to the entry. A final rule published in the Federal Register under Docket HM-215B (62 FR 24689, May 6, 1997), added special provision 120 to § 172.102(c)(1) of the HMR and assigned it to one of the phlegmatized HMT entries for PETN (UN0411). In this final rule, PHMSA is reassigning special provision 120 to UN0411 in Column (7) of the HMT because it never appeared in the subsequent printing of the HMR but the requirement remains valid.

The entry “Petroleum crude oil, UN1267” is revised by adding new special provision 357 instructing a shipper, if applicable, to use the entry “Petroleum sour crude oil, flammable, toxic, UN3494” for petroleum crude oil containing hydrogen sulfide in sufficient concentration that vapors evolved from the crude oil can present an inhalation hazard when this material is offered for transportation internationally. See Section 172.102 Special provisions for a discussion of special provision 357.

The entry “Zinc ammonium nitrate, UN1512” is revised by deleting special provision IP2 which requires IBCs other than metal or rigid plastic IBCs to be offered for transportation in a closed freight container or a closed transport vehicle.

The following Division 1.4, Compatibility Group S (1.4S) explosive article entries in the HMT are revised by adding new special provision 347 which limits the use of the entries to only those articles that have successfully passed Test series 6(d) of Part I of the UN Manual of Tests and Criteria. For clarity, we are also adding the special provision to the entry “Cartridges, power device (used to project fastening devices), ORM-D” to indicate that the requirements for special provision 347 also apply to Division 1.4S articles that may be reclassed as ORM-D. See Section 172.102 Special Provisions for a discussion of new special provision 347.

UN0323	Cartridges, power device.
UN0460	Charges, bursting, plastics bonded.
UN0445	Charges, explosive, commercial without detonator.
UN0441	Charges, shaped without detonator.
UN0500	Detonator assemblies, non-electric for blasting.
UN0456	Detonators, electric for blasting.
UN0366	Detonators for ammunition.
UN0455	Detonators, non-electric for blasting.

The following Division 6.1 (toxic-by-inhalation) materials entries are revised by replacing the portable tank instruction T Code T22 with T20. The UN Committee of Experts on the Transport of Dangerous Goods revised the T Code assignment for a number of Division 6.1 (toxic-by-inhalation) materials from T14 to T20. Assigning T20 requires a higher pressure for the periodic hydrostatic test (6 bar to 10 bar) and a thicker minimum shell thickness (6 mm to 8 mm). This change is consistent with the T Code assigned to the same materials in the HMT. However, for the materials listed below, we assigned a T Code T22 which requires a minimum shell thickness of 10 mm. We do not believe there would be a safety risk in reducing the minimum shell thickness for portable tanks containing these materials from 10 mm to 8 mm. Therefore, for consistency with revisions made to the T Code assignments under the sixteenth revised edition of the UN Model Regulations as well as consistency with the current assignment of T20 to a number of other Division 6.1 (toxic-by-inhalation material) entries, the T Code T20 would be assigned for the following materials.

UN2484	tert-Butyl isocyanate.
UN2481	Ethyl isocyanate.
UN2486	Isobutyl isocyanate.
UN2483	Isopropyl isocyanate.
UN2605	Methoxymethyl isocyanate.
UN2482	n-Propyl isocyanate.

The following Division 6.1 (toxic-by-inhalation) material entries are revised by adding the portable tank special provision TP13 as a conforming amendment to the changes to the PG assignment for these materials (see Amendments to Column (5) above). Special provision TP13 requires the use of self-contained breathing apparatus when the hazardous material is transported by vessel.

UN2668	Chloroacetonitrile.
UN1810	Phosphorous oxychloride.
UN1834	Sulfur chloride.
UN2474	Thiophosgene.

The following organometallic substance entries are revised by adding portable tank special provision TP36 which authorizes use of fusible elements in the vapor space on portable tanks transporting these materials. See Section 178.275 for a discussion of the authorized use of fusible elements on portable tanks.

UN3392	Organometallic substance, liquid, pyrophoric.
UN3394	Organometallic substance, liquid, pyrophoric, water-reactive.
UN3398	Organometallic substance, liquid, water-reactive.
UN3399	Organometallic substance, liquid, water-reactive, flammable.
UN3391	Organometallic substance, solid, pyrophoric.
UN3393	Organometallic substance, solid, pyrophoric, water-reactive.
UN3400	Organometallic substance, solid, self-heating.
UN3395	Organometallic substance, solid, water-reactive.
UN3396	Organometallic substance, solid, water-reactive, flammable.
UN3397	Organometallic substance, solid, water-reactive, self-heating.

The following Division 5.1 (oxidizer) substance entries are revised by adding new special provision W1. Special provision W1 excepts these substances from the HMR for vessel transport when transported in non-friable prill or granule form provided the substance has been successfully tested in accordance with the UN Manual of Tests and Criteria.

UN1486	Potassium nitrate.
UN1498	Sodium nitrate.
UN1499	Sodium nitrate and potassium nitrate mixtures.

Amendments to the Column (8) Packaging Authorizations

The four flammable liquid entries “Alcohols, n.o.s., UN1987,” “Ethanol, UN1170,” “Formaldehyde solutions, flammable, UN1198” and “Isopropanol, UN1219” are revised in Column (8A) by adding reference to § 173.4b for additional exceptions for these materials. Section 173.4b prescribes the requirements for de minimis quantities of hazardous materials offered for transportation and transported by all modes, domestic or international. We are adding a new paragraph (b) to except non-infectious specimens (e.g., museum specimens) preserved with small amounts of certain Class 3 materials from the HMR as recently adopted in the international standards. This amendment is consistent with previous interpretations we have issued on this matter.

The entry “Hydrogen in a metal hydride storage system or Hydrogen in a metal hydride storage system contained in equipment or Hydrogen in a metal hydride storage system packed with equipment, UN3468” is revised in Column (8B) by deleting the reference to § 173.214 for authorized non-bulk packaging and adding new section reference § 173.311. See Section 173.311 for a discussion of authorized packaging provisions for hydrogen in a metal hydride storage system.

The entry “Polyester resin kit, UN3269” is revised by amending Columns (8A) and (8B) to read 165 in reference to packaging provisions in § 173.165. Column (8A) previously referred to § 173.152 and Column (8B) referred to § 173.225 for authorized packaging. For clarity and consistency, such articles are now subject to packaging provisions incorporated into the HMR specific to these articles.

Amendments to the Column (9) Quantity Limitations

We received three comments (3M, IATA, UPS) requesting that PHMSA harmonize with ICAO Technical Instructions amendments that forbid the transport of certain chlorosilane materials in passenger aircraft (UN1818, UN2434, UN2437, UN2986, and UN2987).

We agree. Our original intent was to incorporate these amendments in the August 2010 proposed rule. Therefore, based on our intent and comments received, the following entries are revised by amending the Column (9A) package quantity limitations for passenger air and rail to read “Forbidden,” consistent with the 2011-2012 ICAO Technical Instructions:

UN1818	Silicon tetrachloride.
UN2434	Diphenyldichlorosilane.
UN2437	Methylphenyldichlorosilane.
UN2986	Chlorosilanes, corrosive, flammable, n.o.s.
UN2987	Chlorosilanes, corrosive, n.o.s.

The entries “Medicine, liquid, flammable, toxic, n.o.s., UN3248,” “Medicine, liquid, toxic, n.o.s., UN1851,” and “Medicine, solid, toxic, n.o.s., UN3249” are revised in the Column (9A) and (9B) package quantity limitations authorizing a greater maximum quantity per package consistent an changes made to the 2011-2012 ICAO TI.

Amendments to the Column (10) Vessel Stowage Requirements

Vessel stowage location (10A). For the following materials, we are revising the authorized stowage locations in Column (10A) by revising the stowage category to read D. Assignment of stowage category D means the material must be stowed “on deck only” on a cargo vessel and on a passenger vessel carrying a number of passengers limited to not more than the larger of 25 passengers or one passenger per each 3 meters of overall vessel length. The material is prohibited on passenger vessels in which the limiting number is exceeded.

UN1951	Argon, refrigerated liquid (cryogenic liquid).
UN2187	Carbon dioxide, refrigerated liquid.
UN1143	Crotonaldehyde or Crotonaldehyde, stabilized.
UN1963	Helium, refrigerated liquid (cryogenic liquid).
UN1970	Krypton, refrigerated liquid (cryogenic liquid).
UN1647	Methyl bromide and ethylene dibromide mixtures, liquid.
UN2644	Methyl iodide.
UN2477	Methyl isothiocyanate.
UN2606	Methyl orthosilicate.
UN1913	Neon, refrigerated liquid (cryogenic liquid).
UN2201	Nitrous oxide, refrigerated liquid.
UN2337	Phenyl mercaptan.
UN1810	Phosphorous oxychloride.
UN1834	Sulfur chloride.
UN2474	Thiophosgene.
UN1838	Titanium tetrachloride.
UN2591	Xenon, refrigerated liquid (cryogenic liquids).

Vessel stowage codes (10B). For the following hazardous materials, we are removing from Column (10B) stowage code 18 (stowage code 143 for UN3392), which prohibits the material from being transported on any vessel carrying explosives (except Division 1.4S explosives), and we are adding in its place stowage code 78, which requires the materials to be stowed “separated longitudinally by an intervening complete compartment or hold from” explosives.

UN1131	Carbon disulfide.
UN1259	Nickel carbonyl.
UN3392	Organometallic substance, liquid, pyrophoric.
UN3394	Organometallic substance, liquid, pyrophoric, water-reactive.
UN3194	Pyrophoric liquid, inorganic, n.o.s.
UN2845	Pyrophoric liquids, organic, n.o.s.

Section 172.102 Special Provisions

Section 172.102 lists special provisions applicable to the transportation of specific hazardous materials. Special provisions contain packaging requirements, prohibitions, and exceptions applicable to particular quantities or forms of hazardous materials. PHMSA is adopting the following revisions to § 172.102, special provisions.

Special provision 15 is revised by removing redundant regulatory text applicable to “Chemical kits, UN3316” and “First aid kits, UN3316.”

Special provision 40 is revised to indicate that “Polyester resin kit, UN3269” requires specification outer packaging based on the PG assigned to the base (Class 3) material unless excepted as a limited or excepted quantity material. This revision is a clarification of the existing requirement.

Special provision 77 is deleted. Special provision 77 allows use of the entry “Compressed gas, n.o.s., UN1956” for mixtures of gases with less than 23.5% oxygen when no other oxidizing gases are present. PHMSA is modifying the definition of oxidizing gas in § 171.8 to state that “a gas which may, by providing oxygen, cause or contribute to the combustion of other material more than air does,” meaning, pure gases or gas mixtures with an oxidizing power greater than 23.5% oxygen. Because of the availability of the entry “Compressed gas, oxidizing, n.o.s., UN3156” in the HMT, we believe special provision 77 is no longer necessary.

Special provision 78 is revised to direct shippers to use the entry “Compressed gas, oxidizing, n.o.s., UN3156” to describe compressed air that contains pure gases or gas mixtures with an oxidizing power greater than 23.5% oxygen. PHMSA is modifying the definition of oxidizing gas in § 171.8 of the HMR to indicate that “a gas which may, by providing oxygen, cause or contribute to the combustion of other material more than air does,” meaning, pure gases or gas mixtures with an oxidizing power greater than 23.5% oxygen. Therefore, we are revising this special provision to emphasize the revised definition and use of the proper shipping description.

Special provision 110 is revised to include oxygen cylinders for emergency use. Fire extinguishers (UN1044) are assigned special provision 110, which authorizes the installation of a cartridge power device (of Divisions 1.4C and S) on the fire extinguisher without changing its classification from Division 2.2, provided the actuating cartridge does not contain deflagrating (propellant) explosives exceeding 3.2 g. Many of these types of fire extinguishers are used in commercial aircraft applications where the actuating cartridge is necessary for remote activation to discharge the fire suppressant contained in the cylinder. Similarly, commercial aircraft are being designed to incorporate small oxygen cylinders in the overhead panels above passenger seats to provide emergency oxygen in the event of a depressurization. The design of the system is that a small actuating cartridge attached to each cylinder will be initiated once the passenger starts breathing into the mask, which will allow the flow of oxygen from these cylinders. In connection with the manufacturing and maintenance of the aircraft, it is necessary for these small cylinders to be transported with the actuator installed. The principal hazard presented by these oxygen cylinders remains that of Division 2.2, and not the Division 1.4 explosive hazard of the actuating cartridge. Therefore, in this final rule PHMSA is authorizing the transport of oxygen cylinders for emergency use with an installed actuating cartridge without changing the classification of Division 2.2 provided that the total quantity of deflagrating (propellant) explosives does not exceed 3.2 g per oxygen cylinder, and further provided that the cylinders have an effective means of preventing inadvertent activation.

Special provision 130 is revised in conformance with adoption of new special provision 340 and new § 172.101 HMT entry, “Batteries, nickel-metal hydride, UN3496,” applicable to nickel-metal hydride batteries transported by vessel. Two commenters (PRBA, Saft) requested a revision to clarify the appropriate use of this special provision for the transport of nickel-metal hydride batteries. We agree that special provision 130 should be clarified to avoid confusion over appropriate use of entries applying to nickel-metal hydride batteries. Because these batteries are dry batteries, they are subject to conditions in special provision 130, which outlines that the provision applies to dry batteries when not specifically covered by another entry in the HMT. Because there is now another entry for nickel-metal hydride batteries that is modal specific, there is potential for confusion. We are therefore adding language to special provision 130 clarifying that, except for nickel-hydride batteries shipped under conditions specified in special provision 340 for vessel transportation, nickel-metal hydride batteries are covered by the entry “Batteries, dry, sealed, n.o.s.”

In addition, one commenter (PRBA) suggested that we codify guidance offered in several recently issued letters of interpretation (e.g., Ref. No. 09-0194) indicating our determination that spent or used dry batteries of not more than 9 volts are not likely to generate a dangerous quantity of heat, short circuit, or create sparks during the normal course of transportation and thus, are not subject to the HMR when transported for purposes of recycling, reconditioning, or disposal. We agree. Therefore, in this final rule we are revising special provision 130 by adding a conditional exception for the ground transportation of spent or used dry batteries.

For conformance with the addition of new proper shipping names for UN3166, special provision 134 is revised to specify that a battery-powered vehicle or equipment that also contains an internal combustion engine must be consigned under the entry “Engine, internal combustion, flammable gas powered” or “Engine, internal combustion, flammable liquid powered” or “Vehicle, flammable gas powered” or “Vehicle, flammable liquid powered,” as appropriate. These entries include hybrid electric vehicles powered by both an internal combustion engine and batteries. Furthermore, a battery-powered vehicle or equipment that contains a fuel cell-powered engine must be consigned under the entry “Engine, fuel cell, flammable gas powered” or “Engine, fuel cell, flammable liquid powered” or “Vehicle, fuel cell, flammable gas powered” or “Vehicle, fuel cell, flammable liquid powered,” as appropriate. These entries include hybrid electric vehicles powered by a fuel cell, an internal combustion engine, and batteries.

Special provision 135 is revised to specify that an internal combustion engine installed in a vehicle must be consigned to the entry “Vehicle, flammable gas powered” or “Vehicle, flammable liquid powered,” as appropriate. These entries include hybrid electric vehicles powered by both an internal combustion engine and installed wet, sodium or lithium batteries. If a fuel cell-powered engine is installed in a vehicle, the vehicle must be consigned using the entry “Vehicle, fuel cell, flammable gas powered” or “Vehicle, fuel cell, flammable liquid powered,” as appropriate. These entries include hybrid electric vehicles powered by a fuel cell, an internal combustion engine, and batteries.

Special provision 149 is revised to indicate the exception provided may not be used for transportation by aircraft. This special provision authorizes an increased amount of certain Class 3 (flammable liquid) materials in PG II that are also consumer commodities. We received one comment, from Safety Specialists, Inc. (SSI), opposing the elimination of air eligibility for use of the exception provided in the special provision. SSI asserts that because the materials currently authorized to use the packaging exception provided by special provision 149 are not “extremely” hazardous materials, they should continue to be authorized in air transportation in far greater quantities per inner packaging than are limited quantities packaged under the ICAO Technical Instructions. We disagree. Standardization in today's safety culture enhances safety, lowers training costs and facilitates commerce through greater productivity. PHMSA has made concessions in this final rule, such as lifting the § 175.75 cargo compartment loading restriction on packages of limited quantity materials, to offset per inner and outer packaging limitations adopted through harmonization with the ICAO Technical Instructions. We will also vigorously advocate for change at the international level when warranted.

Special provision 157 is deleted because the language of this provision has been combined with the language of revised special provision 135. Special provision 157 was assigned to the entries “Vehicle, flammable gas powered” and “Vehicle, flammable liquid powered” and instructed shippers that these entries include hybrid electric vehicles powered by both internal combustion engines and installed wet, sodium or lithium batteries. This language is now in special provision 135.

Special provision 167 is revised to require a metal hydride storage system installed in conveyances, to be approved by the Associate Administrator before acceptance for transport. Special provision 167 is also applicable, where appropriate, to UN3166 entries powered by fuel cells.

Special provision 198 is revised to include “Perfumery products, UN1266” among the list of products that nitrocellulose solutions containing not more than 20% nitrocellulose can be transported as. PHMSA is also revising this provision to clarify that the nitrocellulose may not contain more that 12.6% nitrogen by dry mass.

A new special provision 340 is added to provide special instruction for the vessel transport of nickel-metal hydride batteries (including cells). Except for nickel-metal hydride button cells or nickel-metal hydride cells or batteries packed with or contained in equipment, when nickel-metal hydride batteries are loaded in a vessel cargo transport unit in a total quantity of 100 kg gross mass or more, shipment of the nickel-metal hydride batteries is subject to the shipping paper, dangerous cargo manifest requirements under § 176.30, and stowage conditions assigned to the “Batteries, nickel-metal hydride, UN3496” entry in the § 172.101 HMT. Additionally, the nickel-metal hydride batteries are required to be securely packed and protected against a dangerous evolution of heat, short circuits and damage to terminals.

A new special provision 342 is added to be consistent with the adoption of the same provisions in the UN Model Regulations and the IMDG Code as well as amendments made to special provision A131 in the ICAO Technical Instructions. The special provision allows sterilization devices containing ethylene oxide conforming to the conditions in the special provision and packaged in accordance with § 173.4a of the HMR to be offered for transportation and transported by all modes even though Column (9A) of the § 172.101 HMT lists the material as forbidden by passenger aircraft. The addition of this special provision coincides with the deletion of special provision A59 which restricted the applicability of the special provision to air transport. See Special provision A59 for additional discussion of this amendment.

A new special provision 343 is added and assigned to the new HMT entry “Petroleum sour crude oil, flammable, toxic, UN3494,” indicating that for international transportation, this entry in the HMT must be used for petroleum crude oil containing hydrogen sulfide in sufficient concentration that vapors evolved from the crude oil can present an inhalation hazard. However, any bulk packaging used for the domestic transport of petroleum crude oil would be required to be marked in accordance with the new markings prescribed in § 172.327 of the HMR to provide warning of the potential hazard from inhalation of hydrogen sulfide vapors.

A new special provision 345 is added excepting from the requirements of the HMR “Nitrogen, refrigerated liquid cryogenic liquid, UN1977” transported in open cryogenic receptacles with a maximum capacity of 1 L. The receptacles must be constructed with glass double walls having the space between the walls vacuum insulated and each receptacle must be transported in an outer packaging with sufficient cushioning and absorbent materials to protect the receptacle from damage.

A new special provision 346 is added excepting from the requirements of the HMR “Nitrogen, refrigerated liquid cryogenic liquid, UN1977” transported in accordance with the requirements for open cryogenic receptacles in § 173.320 of the HMR. The receptacle must contain no hazardous materials other than the liquid nitrogen which must be fully absorbed in a porous material in the receptacle.

A new special provision 347 is added restricting the use of certain HMT entries classed as Division 1.4S explosive materials to those articles successfully passing Test series 6(d) of Part I of the UN Manual of Tests and Criteria. See Section 172.101 Hazardous Materials Table (HMT) for the list of proper shipping names that are assigned special provision 347. A Division 1.4 explosive is defined as an explosive that presents a minor explosion hazard such that hazardous effects are confined to a package and no projection of fragments of appreciable size or range are expected; and that an external fire must not cause virtually instantaneous explosion of almost the entire contents of a package containing a Division 1.4 explosive. Under § 173.58 of the HMR, an explosive article or substance is subjected to Test Series 6(a), 6(b), and 6(c) for assignment to an appropriate division (e.g. Division 1.4). Explosive articles or substances are assigned to Division 1.4, Compatibility Group S (1.4S) if hazardous effects are confined within a package or the blast and projection effects do not significantly hinder emergency response efforts. Test Series 6(a), 6(b), and 6(c) address hazard effects from exposure of the package to a fire but do not address whether hazardous effects from functioning of the articles or substances is confined within the package. PHMSA is concerned that there is a possibility that products classified as Division 1.4S based on behavior in a fire according to test procedures of Type 6(c) may still produce a hazardous effect that, when initiated, is not confined to a package. Initiation or ignition as a result of fire, after the package is degraded, may produce different results from functioning with the intended means of ignition or initiation. Knowledge of the behavior of the article or substance in both cases is needed to allow proper classification.

As discussed in the comment summary in response to the NPRM, PHMSA is requiring the Type 6(d) test as prescribed in Section 16.7 of the fifth revised edition of the UN Manual of Tests and Criteria in the new special provision 347. For affected articles intended for transportation by aircraft, the compliance date of this new requirement is July 1, 2011. If a manufacturer or approval holder of affected articles previously classed and approved as Division 1.4S chooses to continue offering such shipments as Division 1.4S material by aircraft, the articles must be successfully tested under Test Series 6(d) and a new approval obtained from PHMSA. Additionally, a previously classed and approved Division 1.4S article that is not successfully tested under Test Series 6(d) must be assigned to a compatibility group other than S (e.g., B, C, or D) prior to being transported by aircraft. Based on knowledge that an article or substance will not pass the Type 6(d) test, a manufacturer or approval holder may choose to have a previously approved Division 1.4S explosive reassigned to a different compatibility group based on existing data and recommendation by a PHMSA-approved explosives testing and examination facility in lieu of conducting the Type 6(d) test. For new Division 1.4S articles approved prior to January 1, 2012 intended for domestic highway or rail transportation only, the compliance date for testing to maintain Division 1.4S classification or reassignment to a higher compatibility group other than S is January 1, 2014. For international highway, rail and vessel transportation and domestic vessel transportation, the compliance date for Type 6(d) testing or reassignment for new and previously produced affected articles is January 1, 2012.

A new special provision 349 is added and assigned to “Hypochlorites, inorganic, n.o.s., UN3212” to specify that transport of mixtures of hypochlorite and an ammonium salt is forbidden.

A new special provision 350 is added and assigned to “Bromates, inorganic, n.o.s., UN1450” and “Bromates, inorganic, aqueous solution, n.o.s., UN3213” to specify that transport of ammonium bromate and its aqueous solutions and mixtures of a bromate and an ammonium salt is forbidden.

A new special provision 351 is added and assigned to “Chlorates, inorganic, n.o.s., UN1461” and “Chlorates, inorganic, aqueous solution, n.o.s., UN3210” to specify that transport of ammonium chlorate and its aqueous solutions and mixtures of a chlorate and an ammonium salt is forbidden.

A new special provision 352 is added and assigned to “Chlorites, inorganic, n.o.s., UN1462” to specify that transport of ammonium chlorite and its aqueous solutions and mixtures of a chlorite and an ammonium salt is forbidden.

A new special provision 353 is added and assigned to “Permanganates, inorganic, n.o.s., UN1482” and “Permanganates, inorganic, aqueous solution, n.o.s., UN3214” to specify that transport of ammonium permanganate and its aqueous solutions and mixtures of a permanganate and an ammonium salt is forbidden.

A new special provision 357 is added and assigned to the entry “Petroleum crude oil, UN1267” to clarify that when transported internationally, petroleum crude oil containing hydrogen sulfide in sufficient concentration that vapors evolved from the crude oil can present an inhalation hazard must be transported under the entry “Petroleum sour crude oil, flammable, toxic, UN3494.” As discussed in detail in response to comments submitted to the ANPRM, for domestic transportation, use of the toxic description is not required; however, a bulk package is required to be marked in accordance with the requirement of new § 172.327 of the HMR. See Section 173.327 for a discussion of the marking requirement.

In the August 2010 NPRM, PHMSA proposed to revise special provision A59 for consistency with amendments made to special provision A131 of the 2011-2012 ICAO Technical Instructions. Special provision A59 allows sterilization devices containing ethylene oxide to be offered for transportation and transported by air under the excepted quantity provisions of § 173.4a of the HMR. One commenter (Andersen) supported the amendments to A59 but noted that the special provision originally appearing in the ICAO Technical Instructions (as special provision A131) applicable to air transport has been adopted in the UN Model Regulations as special provision 342 for use by other modes of transport. Additionally, special provision 342 is also to be incorporated into the IMDG Code. The commenter questioned the appropriateness of adopting an “A” prefix special provision which limits the special provision, to air transport only. Andersen stated:

In the preamble to the [NPRM], on page 53085, PHMSA observes that “Special provision A59 allows for sterilization devices containing ethylene oxide to be offered for transportation and transported by air (and thereby all modes) under the excepted quantity provisions of § 173.4a” (emphasis added) * * * notwithstanding PHMSA's statement in regard to the multi-modal applicability of this special provision, it is not at all clear from the wording of § 172.102(c)(2) [A59] * * * that this special provision extends to all modes of transport.

The commenter suggested that, in order to achieve complete harmonization and for greater clarity of the applicability of the special provision, PHMSA revise the applicability of the special provision to all modes and not restrict the special provision to air transport through the use of the “A” prefix as currently implemented.

We agree. Therefore, in this final rule we are deleting Special provision A59 and adopting new Special provision 342 which applies conditions for transportation of sterilization devices containing ethylene oxide to all modes of transportation.

A new Special provision A112 is added authorizing the transportation of certain IBCs by passenger and cargo-only aircraft that contain up to a maximum net quantity of 1,000 kg of an “Environmentally hazardous substance, solid, n.o.s. UN3077.” This amendment is consistent with the authorization in the 2011-2012 ICAO Technical Instructions.

In paragraph (c)(4), the Table 1 (IBC Codes) are editorially revised to remove UN Specifications 31A, 31B and 31N from IBC Codes IB4, IB5, IB6, IB7, and IB8. This revision is consistent with amendments to international standards and removes the specifications from the indicated codes in the table because IBC Codes IB4 through IB8 are assigned to solids, whereas, UN Specifications 31A, 31B, and 31N are authorized for transportation of liquids in IBC Codes IB1 through IB3 which are assigned to liquid materials only.

Paragraph (c)(7) outlines provisions that apply to the transportation of hazardous materials in UN portable tanks. Two commenters (DGAC, PSA) requested that PHMSA revise § 172.102(c)(7) to allow shipment of solid materials in certain portable tanks using bottom outlets. PSA stated:

At the recommendation of the United States, new provisions governing the use of bottom outlets on portable tanks were adopted in the [UN] Model Regulations * * * However, the United States does not follow its own recommendation in the Proposed Rule * * * To date * * * the HMRs flatly prohibit the use of bottom outlets for solids referenced in the American proposal to the U.N. In the Table of Portable Tank T Codes T1-22, which appears in 49 C.F.R. § 172.102(c)(7), instructions T9 and T21 indicate “prohibited” in the column designated “bottom outlet requirements.” The text of § 172.101(c)(7)(ii) explains that the word “prohibited” in that column of the Table “means bottom openings are prohibited.” In the Proposed Rule, and without explanation, the agency did not propose to adopt its own bottom outlet provision.

In the interest of harmonization with specific regard to the January 1, 2011 effective date for international regulations, the commenters urged PHMSA to adopt the provisions we successfully persuaded international organizations to adopt.

We agree. In the paper submitted to the UN Sub-Committee of Experts (UNSCOE) on the Transport of Dangerous Goods (see UN document ST/SG/AC.10/C.3/2007/24 available at http://www.unece.org/​trans/​main/​dgdb/​dgsubc/​c32007.html), the U.S. successfully persuaded UNSCOE to adopt provisions authorizing the use of bottom outlets on portable tanks used to transport PG I solid material on the basis that (1) transport of these materials in portable tanks without bottom openings is impractical and it is virtually impossible to unload the material from the portable tank through top openings; and (2) there is no compelling safety reason to prohibit bottom openings in portable tanks suitable for such material when the authorized portable tanks afford a level of safety in transport substantially greater than that afforded by other packagings authorized for the material (e.g., UN1A2 removable head steel drums). Although PHMSA did not propose this amendment in the August 2010 NPRM, based on comments received and the relief provided to industry by authorizing an alternative method of unloading PG I solid material without a reduction in packaging safety, in this final rule we are revising § 172.101(c)(7) by revising T Codes T9 and T21 to prohibit bottom openings for liquid only and specify applicable requirements for the bottom openings. The revision includes adding clarifying language to § 172.101(c)(7)(ii) to specify the meaning of “prohibited” for liquids in the appropriate context. With regard to PSA's suggested revised regulatory text, we do not believe it is necessary to add language specifying that the bottom outlets must conform to 6.7.2.6.2 of the UN Model Regulations (bottom opening requirements for portable tanks used for solid material) because these provisions are dealt with under § 178.275(d)(2), which we are referencing in the revised entries for portable tank T Codes T9 and T22.

A new portable tank special provision TP36 is added authorizing the use of fusible elements in the vapor space of portable tanks with a gauge test pressure that exceeds 265 kPa (38.4 psig/2.65 bar). See Section 178.275 for a detailed discussion. See Section 172.101 Hazardous Materials Table for a listing of materials assigned this special provision.

A new special provision W1 is added indicating that the hazardous materials “Potassium nitrate, UN1486,” “Sodium nitrate, UN1498,” and “Sodium nitrate and Potassium nitrate mixtures, UN1499” are not subject to the HMR when transported by vessel in non-friable prills or granules form. The material must be accompanied by a certificate from an accredited laboratory stating that the product has been properly sampled and tested by the laboratory according to the UN Manual of Tests and Criteria.

Section 172.200

Section 172.200 prescribes the applicability of shipping paper requirements for the transportation of hazardous materials. Paragraph (b)(3) is revised to remove the exceptions for ORM-D material in conformance with the changes made to the limited quantities requirements under this final rule.

Section 172.203

Section 172.203 specifies additional hazardous materials description requirements on shipping papers. Paragraph (b) is revised to indicate that when a shipping paper is required, a limited quantity must be indicated as such. This revision is necessary due to the shipping paper exception adopted in this final rule for limited quantities intended for transportation by highway or rail.

Section 172.300

Section 172.300 prescribes the applicability of the HMR marking requirements incorporated in subpart D of Part 172. Paragraph (l)(1)(ii) of § 172.101 authorizes up to a one-year transition period for continued use of stock of pre-printed packaging marked with proper shipping names revised in the HMT under a rulemaking. Consistent with the transition period authorized in § 172.101(l)(1)(ii), in this final rule we are amending § 172.300 of the HMR to authorize the continued use of stock of preprinted packaging for one year from the date of compliance or until depleted (whichever is less) for a revision to a required marking. This amendment allows the continued use of preprinted packaging stock that is marked in accordance with the manner previously authorized.

Section 172.301

Section 172.301 prescribes general marking requirements for non-bulk packagings. In this final rule, PHMSA is amending paragraph (a) to clarify that a proper shipping name and identification number is not required to be marked on package containing only limited quantity material marked in accordance with § 172.315(a). Additionally, it is amended by adding that until January 1, 2014 (January 1, 2013 if intended for transportation by aircraft), an identification number is not required to be marked on package containing only a Consumer commodity, ORM-D or ORM-D-AIR material, as defined in § 171.8 of this subchapter in effect on October 1, 2010, provided the package is marked in accordance with § 172.316.

Section 172.312

Section 172.312 prescribes the required orientation markings for non-bulk packages containing liquids. PHMSA is amending paragraph (c)(5) to clarify that the exception applies only to a hermetically sealed inner packaging or receptacle not exceeding 500 mL each.

Section 172.315

Section 172.315 specifies the markings required on a package containing limited quantities of hazardous materials. These new markings are consistent with the UN Model Regulations, ICAO TI and IMDG Code and are required on packages of limited quantities offered for transportation by highway, rail, air and vessel. Additionally, PHMSA received positive comments submitted in response to the ANPRM concerning the new marking because the requirement specifies minimum dimensions on each side (100 mm) that substantially increases the visibility of the marking when compared with the current ORM-D marking prescribed in § 172.316 of the HMR. Commenters stated that increased visibility of the mark will enhance safety while reducing regulatory burden.

For limited quantities intended for transportation by vessel, this new marking with minimum dimensions of 250 mm on each side is required on cargo transport units containing limited quantities and no other hazardous materials. For limited quantities intended for transportation by aircraft, the marking requirements are consistent with the 2011-2012 ICAO TI (i.e., “Y” mark on a white square on point) in addition to any required labels.

Section 172.316

Section 172.316 prescribes marking requirements for packages containing materials classed as ORM-D and ORM-D-AIR. The marking prescribed in this section will no longer be authorized for limited quantities effective January 1, 2014.

Section 172.322

Section 172.322 prescribes marking requirements for packages containing marine pollutants. PHMSA is adding an exception from the marking requirement in new paragraph (d)(4) for packages of limited quantities marked in accordance with § 172.315.

Section 172.324

Section 172.324 prescribes marking requirements for packages containing hazardous substances in non-bulk packagings. PHMSA is revising paragraph (b) for packages containing hazardous substances marked in accordance with the limited quantity marking prescribed in § 172.315.

Section 172.326

Section 172.326 prescribes the marking requirements for portable tanks. In this final rule, we are revising paragraph (a) to align with the IMDG Code the minimum height for a proper shipping name marked on a portable tank to 65 mm when offered for transportation and transported by vessel. This amendment is in response to a revision made in Amendment 35-10 of the IMDG Code.

One commenter (Arkema) requests that we allow a one year transition period from the publication of the final rule to allow for depletion of label inventory and/or restenciling of portable tanks. We agree that there should be a transition period and note that, in this final rule, we are implementing a delayed compliance date of January 1, 2012, which is one year from the effective date of the rule, unless otherwise specified in provisions adopted or revised in this final rule.

Section 172.327

New section 172.327 specifies the marking required for a bulk packaging containing petroleum crude oil to warn of the potential toxic inhalation hazard from vapors evolved from hydrogen sulfide present in the crude oil. PHMSA proposed to require placement of the marking used for toxic materials under the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in the immediate vicinity of any location on a bulk packaging that could pose a health risk to transportation workers if exposed to hydrogen sulfide vapors emitted from that location, such as loading heads and manholes. This proposed hazard communication marking requirement is applicable to bulk packagings in domestic transportation only. The new hazardous materials description for “Petroleum sour crude oil, flammable, toxic, UN3494” added to the HMT must be used for international transportation of petroleum crude oil with hydrogen sulfide in sufficient concentration that vapors evolved from the crude oil present an inhalation hazard (for both bulk and non-bulk packagings).

One commenter (AAR) expressed concern that this new marking requirement would place an undue burden on rail carriers with regard to inspection requirements under § 174.9 of the HMR. The commenter had concerns regarding the safety of rail carrier employees having to climb tank cars to determine whether markings are present or correct. AAR stated:

[We] we would not oppose the proposed marking if it were made clear that railroads have no obligation to inspect for markings. Accordingly, [we suggest] amending [§ 173.127 to indicate] carrier personnel are not required to inspect for markings that would not be visible or legible from the ground.

We agree, although we do not believe a regulatory revision is warranted. Section 174.9 requires a rail carrier to inspect each rail car containing a hazardous material, at ground level, for required markings, labels, and placards, etc. This requirement already limits the inspection to ground level and predisposes the carrier from having to climb onto a rail car to inspect for hazard communications. As indicated in the comments by AAR, the intent of this marking is to alert hazmat employees who may be exposed to hydrogen sulfide vapors during a loading or unloading operation to a potential hazard and not to communicate the hazard for emergency response purposes. Thus, carriers will not be obligated to inspect for markings placed in the vicinity of tank car openings on a rail car that are not readily visible or legible from ground level.

Based on comments received, we are revising our proposed requirements to authorize an alternative marking to the GHS toxic material pictogram. See the Sections II.C and III.A.7 discussion of the classification of petroleum sour crude oil.

Section 172.500

Section 172.500 specifies the applicability of placarding requirements to certain materials. PHMSA is amending paragraph (b)(3) to clarify that limited quantities marked in accordance with revised § 172.315 of the HMR are not subject to placarding requirements.

Section 172.502

Section 172.502 specifies prohibited and permissive placarding requirements. In this final rule, PHMSA is revising the exceptions provided in paragraph (b)(2) to include the petroleum sour crude oil marking and the limited quantity marking in §§ 172.315 and 172.327 of the HMR, respectively.

Part 173

Section 173.4

Section 173.4 prescribes the requirements for small quantities of hazardous materials offered for transportation and transported by domestic highway or rail. PHMSA is revising paragraph (a) and adding new paragraph (a)(1)(v) to allow Division 2.2 (non-flammable, non-poisonous, compressed gas) material without a subsidiary hazard (except for aerosols) without applying for an approval from the Associate Administrator as prescribed under paragraph (c) of this section. Other Class 2 materials, including Division 2.2 aerosols, will still require approval under § 173.4(c) of the HMR. These amendments are consistent with the authorization under § 173.4a(b)(1) for Division 2.2 gases without a subsidiary hazard in addition to the new restriction to exclude aerosols from authorized materials in § 173.4a of the HMR. See Section 173.4a for a discussion of revisions for excepted quantities of hazardous materials.

Section 173.4a

Section 173.4a prescribes the requirements for excepted quantities of hazardous materials offered for transportation and transported by all modes, domestic or international. PHMSA is amending paragraph (a) by adding a new paragraph (a)(4) regarding pressure differential capability for packages intended for transportation by aircraft in accordance with § 173.27(c) of the HMR. PHMSA is also amending paragraph (b)(1) to clarify that the authorization for Division 2.2 (non-flammable, non-poisonous, compressed gas) excludes aerosols as an excepted quantity material. Such articles are authorized as a limited quantity under both domestic and international standards. Additionally, PHMSA is revising paragraph (b)(5) to add polyester resin kits to the types of Division 5.2 (organic peroxide) material authorized as an excepted quantity and is revising paragraph (d)(3) by correcting the outer packaging aggregate quantity limit for Division 5.2 liquids from 250 mL to 500 mL. Lastly, PHMSA is adding a new paragraph (g)(3) that requires when packages of excepted quantities (see the Section 173.25 discussion) are contained in an overpack, and the package markings required by this section are not visible inside the overpack, the excepted quantities marking must also be placed on the overpack. Additionally, an overpack containing packages of excepted quantities is not required to be marked with the word “OVERPACK.”

Section 173.4b

Section 173.4b prescribes the requirements for de minimis quantities of hazardous materials offered for transportation and transported by all modes, domestic or international. Consistent with the international standards, PHMSA is adding a new paragraph (b) to except non-infectious specimens (e.g., museum specimens) preserved with small amounts of certain Class 3 (flammable liquid) materials for scientific purposes from the requirements of the HMR. This amendment is consistent with previous interpretations we have issued on this matter indicating these specimens do not pose a risk to safety during the course of transportations.

One commenter (AVMA) expressed support for the adoption of this exception as essential to the conduct of professional work of veterinarians. Therefore, in this final rule, we are adopting the exception from full regulation under the HMR for non-infectious specimens preserved with small amounts of certain Class 3 (flammable liquid) material for scientific purposes.

Section 173.25

Section 173.25 prescribes the requirements for certain authorized packagings and overpacks. Consistent with the international standards, PHMSA is requiring an overpack containing packages of limited quantity material marked with the new limited quantities marking required by this final rule (see the Section 172.315 discussion) to be marked with the word “OVERPACK” if the markings are not visible, in addition to all other required package markings. This mark is an indication that the packages contained within the overpack are in accordance with the HMR. Additionally, for excepted quantities (see the Section 173.4a discussion) where the required package markings are not visible inside an overpack, the excepted quantities marking must also be placed on the overpack. An overpack containing packages of excepted quantities is not required to be marked with the word “OVERPACK.”

Section 173.27

Section 173.27 prescribes the general requirements for packaging offered or intended for air transportation. In this final rule, PHMSA is amending paragraph (f) by adding a new Table 3 that outlines the requirements for limited quantities intended for air transportation consistent with the 2011-2012 ICAO Technical Instructions, where appropriate. See the limited quantity, consumer commodity and ICAO Technical Instructions alignment NPRM comment discussion in Section III.A.5 of this rule.

Section 173.40

Section 173.40 specifies the general packaging requirements for toxic materials packaged in cylinders. PHMSA is amending paragraph (c)(1) concerning closure requirements by requiring the valve connections on UN Specification cylinders to be made by a taper thread or some other means in accordance with ISO Standard 10692-2:2001.

Section 173.58

Section 173.58 outlines the assignment of class and division for new explosives. Based on a recommendation from comments provided by IME, we are revising paragraph (a)(5) to include a reference to the Type 6(d) test for determination of Division 1.4S classification for consistency with the adoption of the new test.

Section 173.59

Section 173.59 provides definitions of explosive terms that are intended for information only. The UN Committee of Experts (COE) recently defined the term “phlegmatized” to meaning the addition of a substance to an explosive to enhance its safety in handling and transport. One commenter indicated support for adoption of the proposed definition of “phlegmatized,” therefore, in this final rule PHMSA is adopting the definition in the HMR as proposed.

Section 173.63

Section 173.63 specifies packaging exceptions for limited quantities of certain Division 1.4S explosive articles authorized for reclassification and transport as ORM-D material. Prior to offering for transportation by aircraft, “Cartridges, power devices, ORM-D-AIR” (UN0323), must have been successfully tested in accordance with the new UN Test Series Type 6(d) test beginning July 1, 2011. See the Section 172.102, Special Provision 347 discussion. This requirement is a condition for the continuation of a Division 1.4S classification and for reclassification to ORM-D for limited quantities of such articles intended for transportation by international highway, rail and vessel and domestic vessel effective January 1, 2012. Limited quantities of such articles approved as Division 1.4S prior to January 1, 2012, may continue to be reclassed as ORM-D and offered for domestic highway and rail transportation only until January 1, 2014.

Section 173.120

Section 173.120 defines Class 3 (flammable liquid) material. PHMSA is revising paragraph (c) to add new testing methods for determining the flash point of a liquid. See Section 171.7 for a listing of materials incorporated by reference pertaining to § 173.120.

Section 173.121

Section 173.121 prescribes the packing group assignment for flammable liquids. The HMR do not specify a test method for determining the boiling point of a liquid which may be necessary for liquids with very low flash points. PHMSA is revising paragraph (a) to add new testing methods for determining the boiling point of a liquid. See Section 171.7 for a listing of materials incorporated by reference pertaining to § 173.121.

Section 173.124

Section 173.124 defines Class 4 material. For consistency with a revision adopted in the UN Model Regulations, PHMSA is amending the definition of “self-heating” in § 173.124(b)(2) of the HMR to read: “Self-heating of a substance is a process where the gradual reaction of that substance with oxygen (in air) generates heat. If the rate of heat production exceeds the rate of heat loss, then the temperature of the substance will rise which, after an induction time, may lead to self-ignition and combustion.”

Section 173.137

Section 173.137 establishes test criteria and packing group assignments for Class 8 (corrosive) material. Since 1993, PHMSA has authorized under the terms of a special permit (i.e., DOT-SP 10904) an in vitro test method (available commercially as Corrositex®) as an alternative form of testing to that specified in the HMR, which is based on live animal test results, to determine the corrosivity of certain materials. Materials authorized for analysis using the alternative test method include acids (and their derivatives), acyl halides, alkylamines and polyalkylamines, bases, chlorosilanes, metal halides, and oxyhalides.

The UN COE recently recognized and adopted in vitro test methods in the UN Model Regulations as an alternative form of testing to that specified in OECD Guideline for Testing of Chemicals, Number 404, “Acute Dermal Irritation/Corrosion.” The following alternative in vitro test methods include OECD Guidelines for the Testing of Chemicals:

• No. 430, “In Vitro Skin Corrosion: Transcutaneous Electrical Resistance Test (TER)” (2004);
• No. 431, “In Vitro Skin Corrosion: Human Skin Model Test” (2004); and
• No. 435, “In Vitro Membrane Barrier Test Method for Skin Corrosion” (2006).

A positive test result under in vitro methods 430 and 431 may be used to determine corrosivity for transportation purposes but cannot be used to determine the PG assignment. A negative result for corrosivity under in vitro methods 430 and 431 can preclude further testing to determine PG assignment using method 404, the current OECD Guideline involving in vivo testing, or method 435, the newly adopted OECD Guideline involving in vitro testing.

Based on the adoption of three new OECD guidelines for the in vitro testing of materials for corrosivity in the UN Model Regulations and through encouragement from PETA to adopt these new test methods in a petition for rulemaking (P-1550), we proposed to adopt such guidelines as matter incorporated by reference (IBR) in §§ 171.7 and 173.137 of the HMR.

In response to our proposal to incorporate several in vitro test methods for determination of corrosivity, PHMSA has received over 900 comments supporting the proposal, including a comment from PETA. We received no opposition. Therefore, we are adopting the OECD Guideline Test Nos. 430, 431, and 435, and revising Test No. 404 as proposed. Further, PETA urged PHMSA to facilitate access to DOT-SP 10904 through our Web site until such a time that this final rule becomes effective, and requested that PHMSA remove letters of interpretation that they believe recommend the use of in vivo testing even though alternative in vitro testing is available.

With regard to PETA's additional requests, they are beyond the scope of this rulemaking. However, we note that in prior correspondence with PETA, PHMSA has indicated that information about DOT-SP 10904 can be obtained by entering “Corrositex” in the search feature of the PHMSA Office of Hazmat Safety Web site. Also, the special permit may be accessed by entering “10904” in the search feature on our special permits Web site or by conducting a group number search.

We agree with PETA that non-live animal testing should be used where available and encourage shippers to use the in vitro test methods to determine the classification of a material as corrosive and assignment of a packing group. We also remind shippers that historical data may also be used to classify a material in accordance with § 173.136(c). Thus, in this final rule we are revising § 173.136(a) to codify the authorization to use in vitro test methods and to highlight the availability of classifying a material based on historical data.

Sections 173.150, 173.151, 173.152, 173.153, 173.154 and 173.155

Sections 173.150 through 173.155 prescribe the exceptions for certain Class 3, 8 and 9 and Division 4.1, 4.2, 4.3, 5.1, 5.2, 6.1 hazardous materials under the HMR. In this final rule, PHMSA is revising each of these sections to recognize the UN Model Regulations and IMDG Code package quantity limits for the highway, rail, and vessel transportation of limited quantities. No limited quantity limits decrease and two increase slightly to maintain alignment with the international standards for transport by other than aircraft. Additionally, the packaging provisions for “Polyester resin kits” are removed from § 173.152, as proposed, and placed in new § 173.165 for clarity.

When PHMSA lowered the quantity limits for Division 6.1 (poisonous) materials of PG II (primary or subsidiary) authorized as a limited quantity in a final rule published under Docket HM-215G (70 FR 34065, June 13, 2005), it did not authorize the labeling exception for such packages when intended for transportation by highway, rail and vessel, nor did it authorize renaming and reclassification as “Consumer commodity, ORM-D” for such materials. In this final rule, except for transportation by aircraft, we are authorizing the labeling exception for packages of limited quantity material with a Division 6.1, PG II primary or subsidiary hazard and, until December 31, 2013, we are authorizing renaming and reclassification as “Consumer commodity, ORM-D”. Additionally, until December 31, 2012, a consumer commodity as defined in § 171.8 in effect on October 1, 2010 may continue to be packaged, reclassed and marked “ORM-D-AIR” either in accordance with the new Table 3 of § 173.27(f) or §§ 173.150 through 173.155 and 173.306, as applicable. PHMSA fully believes this eventual alignment with international standards will improve clarity, promote regulatory compliance, reduce employee training costs and enhance safety overall.

Section 173.161

Section 173.161 prescribes packaging requirements for chemical kits and first aid kits containing small amounts of hazardous materials. In this final rule, PHMSA is editorially revising the section. In addition, PHMSA is authorizing transport of dry ice in accordance with § 173.217 in packaging authorized under this section when used as a refrigerant for the contents of a kit.

Section 173.165

A new section 173.165 is added to prescribe packaging and other requirements for “Polyester resin kits, UN3269” formerly contained in § 172.102, special provision 40 and § 173.152(b)(4) of the HMR. This amendment is intended to provide clarification of existing requirements while also harmonizing the HMR with international standards.

Section 173.167

A new section 173.167 is added to indicate authorized materials and quantity limits for articles and substances that may be described as “ID8000, Consumer commodity,” when intended for transportation by all modes of transport provided all or some of the transportation is by aircraft. Such articles and substances eligible for classification or reclassification to Class 9 are Class 2 materials (non-toxic aerosols only), Class 3 materials (Packing Group II and III only), Division 6.1 (Packing Group III only), UN/NA3077, UN/NA3082, and UN3175, provided such materials do not have a subsidiary risk and are authorized aboard a passenger-carrying aircraft. Inner and outer packaging quantity limits are based on Packing Instruction Y963 of the 2011-2012 ICAO TI. Specification outer packagings are not required under the conditions prescribed in this section. Additionally, the pressure differential capability of the inner packagings of a combination packaging intended to contain liquids is reduced from 95 kPa to 75 kPa for materials offered for transportation and transported by aircraft under the provisions of this section.

Section 173.220

Section 173.220 provides exceptions from regulation under the HMR for the transport of internal combustion engines, self-propelled vehicles, mechanical equipment containing internal combustion engines, and battery-powered vehicles or equipment. This section is revised to include engines, vehicles, and equipment powered by fuel cells consistent with similar provisions under international standards.

Section 173.225

Section 173.225 specifies packaging requirements and other provisions for organic peroxides. When the § 172.101 HMT specifies this section, the organic peroxide must be packaged and offered for transportation in accordance with the provisions of this section. Each packaging must also conform to the general requirements of Subpart B of Part 173 and to the applicable requirements of Part 178 of the HMR. Specifically, organic peroxides that require temperature control are subject to § 173.21(f). When an IBC or bulk packaging is authorized and meets the requirements of paragraph (f) or (h) of § 173.225, respectively, lower control temperatures than those specified for non-bulk packaging may be required. An organic peroxide not identified in paragraph (c), (e), or (g) of § 173.225 by technical name, or not assigned to a generic type in accordance with paragraph (b)(3) of this section, must conform to the requirements in paragraph (c) of § 173.128.

The Organic Peroxides Table specifies by technical name those organic peroxides that are authorized for transportation and not subject to the approval provisions of § 173.128. An organic peroxide identified by technical name is authorized for transportation only if it conforms to all applicable provisions of the table. In this final rule, PHMSA is amending the Organic Peroxide Table in § 173.225(c)(8) by adding a new entry and revising current entries. We are revising an entry to the Organic Peroxide IBC Table in paragraph (e) of this section.

The following entries in the Organic Peroxide Table are being revised:

UN3106	Di-(2-tert-butylperoxyisopropyl) benzene(s).
Exempt	Di-(2-tert-butylperoxyisopropyl) benzene(s).
UN3105	2,5-Dimethyl-2, 5-di-(tert-butyl­peroxy) hexane.

The following entry is added to the Organic Peroxide Table:

UN3103	2,5-Dimethyl-2, 5-di-(tert-butyl­peroxy) hexane.

One commenter (Arkema) requested that PHMSA provide a packing method exception for domestic transportation of greater than 90% concentrations of this material based on a history of safe transportation. The proposed revision to this entry changed the packing method for this material in concentrations of 90-100% from OP7 to OP5, reducing the maximum quantity per package from 60 L to 30 L per package. Arkema stated:

[We ship] a 97% solution in 100 pound drums. Since August 2005 we have shipped [approximately] 1,800,000 pounds. We have had only one incident in the 5 year time period. This incident was the result of a pallet nail puncture. We suggest that a note be added to column (8) for domestic shipments [that] OP7 is authorized.

We disagree. The UN Committee of Experts adopted the reclassification of 90-100% concentrations of 2, 5-Dimethyl-2, 5-di-(tert-butylperoxy) hexane, which entails the more conservative packing method OP5, based on a proposal submitted by the German competent authority. Available industry test data from results on this material at concentrations greater than 90% using the E1 Koenen test in the UN Manual of Tests and Criteria varies from 1.5-2.0 mm. Based on differences in industry test results, the German competent authority conducted a number of E1 Koenen tests on various concentrations of 2, 5-Dimethyl-2, 5-di-(tert-butylperoxy) hexane exceeding 90%. Their conclusion was that the limiting diameter is 2.0 mm at concentrations above 90%, and therefore, they proposed a reclassification from an “Organic Peroxide, Type D, liquid, UN3105” to an “Organic Peroxide, Type C, liquid, UN3103” for 90-100% concentrations of 2, 5-Dimethyl-2, 5-di-(tert-butylperoxy) hexane to the UNSCOE (see UN working document ST/SG/AC.10/C.3/2008/66 available on the UNSCOE Web site).

We applaud Arkema's safe record of transportation using packing method OP7 for a greater than 90% concentration of material. However, based on data provided by the German competent authority indicating a more conservative classification, in this final rule, we are keeping this entry as proposed. We invite Arkema to submit test results for their 97% solution of 2, 5-Dimethyl-2, 5-di-(tert-butylperoxy) hexane should the results indicate a classification that differs from the entry adopted in this final rule.

The following entry in the Organic Peroxide IBC Table is being revised to authorize a 31H2 freestanding, rigid plastic IBC:

UN3109	Peroxyacetic acid, stabilized, not more than 17%.

Section 173.230

Section 173.230 prescribes the requirements for fuel cells offered for transportation by all modes. In paragraph (g), PHMSA proposed to allow only those fuel cells containing flammable liquids and corrosive materials to be transported as a limited quantity by aircraft. In paragraph (h), PHMSA also proposed prohibiting the reclassification to “Consumer commodity, ORM-D-AIR” for transportation by aircraft. Several commenters (BIC, COSTHA, DGAC, IATA, LSI, Signa, Trulite, USFCC) expressed strong disapproval to not extending the limited quantity provisions to fuel cell cartridges containing either Division 2.1 (flammable) gas or water-reactive solids. They noted that the only difference between authorizing and not authorizing these materials as limited quantities is the required use of UN specification packaging and that PHMSA offers no safety rationale for this exclusion as the fuel cell cartridges themselves are subject to much more stringent construction, testing, and packaging requirements than for similar articles (e.g., aerosols).

We agree. In this final rule, based on comments received, we are authorizing the transportation of flammable gas and water-reactive solid fuel cell cartridges as limited quantities in addition to authorizing their transport as consumer commodities (except for transportation by aircraft) if all conditions for limited quantity provisions are met.

Section 173.301b

Section 173.301b prescribes general requirements for shipment of UN pressure receptacles. PHMSA is revising paragraph (c)(2)(iii) to indicate that valve protection requirements for metal hydride storage systems are specified in ISO 16111. Additionally, we are revising paragraph (e) regarding the integrity of UN pressure receptacles used for pyrophoric gases or flammable mixtures of gases containing more than 1% pyrophoric compounds in accordance with the sixteenth revised edition of the UN Model Regulations.

Section 173.306

Section 173.306 prescribes the requirements for limited quantities of compressed gases. PHMSA is revising paragraph (h) to clarify that, except for transportation by aircraft, lighter refills in the ORM-D hazard class are eligible for the exceptions in paragraph (i) of this section and in § 173.156. Additionally, PHMSA is revising paragraph (i) of the section to recognize the new marking for limited quantities of such materials and to provide a transitional period for the eventual elimination of the ORM-D hazard class. PHMSA is also editorially revising paragraph (l) for clarity.

Section 173.307

Section 173.307 establishes exceptions for compressed gases. In this final rule, PHMSA is adding certain types of light bulbs to the section provided they are packaged appropriately so that if a bulb ruptures all pieces are contained within the package.

Section 173.311

PHMSA is adding a new § 173.311 to prescribe the packaging requirements for “Metal hydride storage systems, UN3468” used for the transport of hydrogen as proposed. A metal hydride storage system is a single complete hydrogen storage system that includes a receptacle, metal hydride, a pressure relief device, a shut-off valve, service equipment and internal components.

The HMR do not prescribe specific packaging or shipping methods for metal hydride storage systems containing hydrogen. However, PHMSA has issued a number of special permits to allow the use of these systems for transport. The UN Model Regulations, in new Packing Instruction P205, prescribe standards for the construction, qualification, marking and requalification of such systems and are the basis for the new HMR requirements. Some amendments in new § 173.311 include:

• Application to transportable metal hydride storage systems with pressure receptacles not exceeding 150 liters in water capacity and having a maximum developed pressure not exceeding 25 MPa.
• Requirement that transportable metal hydride storage systems be designed, constructed, initially inspected and tested in accordance with ISO standard 16111:2008, “Transportable gas storage devices—Hydrogen absorbed in reversible metal hydride,” as authorized under § 178.71(f) (formerly reserved).
• Requirement that steel pressure receptacles or composite pressure receptacles with steel liners be marked in accordance with § 173.301b(f) of the HMR, which specifies that a steel UN pressure receptacle bearing an “H” mark must be used for hydrogen bearing gases or other gases that may cause hydrogen embrittlement.
• Requirement of a requalification interval of no more than five years as specified in § 180.207 of the HMR in accordance with the requalification procedures prescribed in ISO 16111.

Section 173.322

Section 173.322 prescribes various packaging methods for ethyl chloride. In this final rule, PHMSA is adopting the amended provisions from packaging instruction P200 of the UN Model Regulations for ethyl chloride in a new paragraph (e). This new packaging method authorizes ethyl chloride in capsules not exceeding 150 g of gas each, closed with a secondary means applied, and placed in a strong outer packaging not to exceed 75 kg gross mass.

Part 175

Section 175.8

Section 175.8 provides exceptions from certain regulations for air carrier operator equipment and items of replacement. PHMSA is revising paragraph (b)(3) to clarify that transportation of alcoholic beverages, perfumes, colognes, and liquefied gas lighters carried aboard a passenger-carrying aircraft by an operator must be for use or sale of those items on that specific aircraft.

Two commenters (AA, COSTHA) requested that PHMSA align paragraph (b)(3) with the ICAO TI to permit onboard use of aerosols. COSTHA noted:

A number of carriers currently are required to obtain a special permit to transport aerosols in Division 2.2, specifically for the dispensing of whipped cream or other food products * * * We believe if this list was amended by including “aerosols” this issue would be resolved.

We agree. Therefore, in this final rule we are revising paragraph (b)(3) to authorize use of Division 2.2 aerosols to dispense food products.

Section 175.9

Section 175.9 prescribes the applicability of the HMR to special aircraft and rotocraft operations. This section also prescribes the conditions under which certain operations may be performed in accordance with 14 CFR and 49 CFR (e.g., avalanche and weather control). In this final rule, PHMSA is emphasizing that rotocraft operations are fully subject to both sets of regulations.

One commenter suggested revising paragraph (b)(6) to provide clarity. IME stated:

This suggested language is consistent with [§] 177.835(g), which addressed the identical compatibility issue between explosives and detonators that are transported on the same conveyance. In addition, use of the terms “dynamite” and “blasting caps” without the additional reference to Division 1.1, 1.2, and 1.3 material could lead to the unintentional misinterpretation or misapplication of the rule.

We agree. Based on the comment provided, we are revising § 173.59(b)(6) to provide clarification.

Section 175.10

Section 175.10 specifies the conditions for which passengers, crew members or an operator may carry hazardous materials aboard an aircraft. PHMSA is adding a new paragraph (a)(17) to permit a mobility aid such as a wheelchair, containing a lithium ion battery, to be transported in accordance with the exceptions provided in this section. A wheelchair or other mobility aid that contains a lithium metal battery is not permitted aboard a passenger-carrying aircraft. As a result of this amendment, current paragraph (a)(17) is redesignated as paragraph (a)(18) and current paragraph (a)(18) is redesignated as paragraph (a)(19).

Three commenters (IATA, PRBA, Scoot) supported our proposal to add a new paragraph providing an exception for wheelchairs or other mobility aids containing a lithium ion battery, but requested that for consistency, we further align with the ICAO TI and accommodate carriage of these items by disabled passengers by allowing carriage in the aircraft cabin. For instance, Scoot shared:

Our mobility scooter [is] designed to fold up and be stowed in the passenger cabin * * *. They are often small enough to fit in the overhead bin. [T]he lithium-ion batteries are removed and hand-carried by the passenger in the same manner as * * * lithium-ion batteries used for consumer electronics.

PRBA expressed disappointment that PHMSA did not address authorizing passenger transport of certain medical devices powered by lithium metal batteries in this final rulemaking. We recognize the need for persons with medical disabilities to be able to carry devices powered by lithium metal batteries aboard a passenger-carrying aircraft. However, such a provision will be addressed in a separate rulemaking.

Paragraph (a)(19) is being revised to allow passengers and crew members to place certain spare fuel cell cartridges in checked baggage. This exception currently does not apply to Divisions 2.1 or 4.3 materials contained in spare fuel cell cartridges. Although the ICAO TI only restricts spare fuel cell cartridges containing Division 4.3 liquid materials from checked baggage, PHMSA strongly believes that the restriction must also include spare cartridges containing Division 2.1 materials. Thus, PHMSA proposed to allow spare fuel cell cartridges containing flammable and corrosive liquids in checked baggage while continuing to require spare fuel cell cartridges containing Division 2.1 and 4.3 materials to be carried aboard an aircraft in carry-on baggage only.

One commenter (ALPA) supported our position while several commenters (COSTHA, DGAC, IATA, JEMA, PRBA, TAEC, Trulite, USFCC) voiced strong opposition to our proposal to limit fuel cell cartridges permitted in checked baggage to those with flammable liquid or corrosive liquid fuels. As several commenters indicated, PHMSA did not provide data or analysis supporting the proposal, while tests performed at the FAA Technical Center on fuel cell cartridges containing flammable liquid material indicated that in the case of a fire involving these materials, the fire can be readily extinguished with current fire suppression systems onboard an aircraft.

Because Division 2.1 flammable gases are generally prohibited in air transportation on a passenger-carrying aircraft as cargo and due to the questionable integrity of such articles when packed in a passenger's checked baggage, PHMSA is adopting the prohibition in checked baggage of fuel cell cartridges containing Division 2.1 flammable gases and Division 4.3 solid dangerous when wet materials as proposed.

Section 175.25

PHMSA currently requires operators to provide certain information to passengers regarding what hazardous materials they may check-in or carry-on a flight. Effective January 1, 2013, this information is to be provided at points of ticket sale and at automated or remote passenger check-in. Consistent with the ICAO TI, these amendments will require a passenger to acknowledge such limitations before a ticket purchase and automated or remote check-in can be finalized. PHMSA believes these amendments only clarify existing regulatory requirements in § 175.25 that have not been updated due to changing technologies used by air carriers to either sell tickets (Internet) or check-in passengers (automated kiosks). Additionally, these amendments provide air carriers greater flexibility in how the information they are required to provide passengers on hazardous materials is disseminated to them.

Section 175.30

Section 175.30 prescribes inspection procedures for operators. PHMSA is revising paragraph (e) regarding overpack marking requirements for packages of limited and excepted quantities offered for transportation by aircraft.

Section 175.75

Section 175.75 prescribes quantity limitations and cargo location requirements for hazardous materials transported by aircraft. PHMSA is revising paragraph (e) to correct an inadvertent cargo compartment restriction for passenger-authorized materials carried aboard a cargo-only aircraft published in a final rule under Docket HM-215J (74 FR 2267, January 14, 2009). PHMSA is also revising paragraph (f) Quantity and Loading Tables for clarity.

Several commenters (ALPA, COSTHA, PRBA, UPS) objected to our inclusion of limitations on the stowage of lithium batteries in § 175.75 of the HMR and strongly urged that the limitations be removed from this rulemaking and addressed in a separate lithium battery rulemaking such as HM-224F. We agree. All reference to lithium batteries in our revisions to § 175.75 are removed from this rulemaking.

One commenter (UPS) fully supported our proposed clarification of the use of the Class C cargo compartment for shipments of material eligible for passenger aircraft under § 175.75(d); however, UPS did recommend an additional revision for clarity. Therefore, in this final rule we are revising paragraph (d) further to incorporate a second note into the table to clarify that for cargo-only aircraft, packages required to be loaded in a position considered accessible include those loaded into a Class C cargo compartment.

Several commenters requested that PHMSA offer the same exception from the loading restrictions in § 175.75 for limited quantity packages as are currently authorized for Class 9 and ORM-D-AIR materials. We agree that such packages should be afforded the same exceptions from the loading restrictions of § 175.75 as ORM-D-AIR materials and are revising the section accordingly.

Section 175.78

Section 175.78 prescribes the stowage compatibility of hazardous materials offered for transportation by aircraft. PHMSA is revising paragraph (c)(4)(iii) to specify that, except as provided in paragraph (c)(4)(iv) of § 175.78, Division 1.4B explosive materials may only be stowed together with Division 1.4S explosive materials. This revision is in accordance with an amendment made in the 2011-2012 ICAO Technical Instructions.

Part 176

Section 176.2

Section 176.2 establishes definitions specific to the transportation of hazardous materials by vessel. PHMSA is revising the definition for “Cargo transport unit” to include a multiple-element gas container or MEGC.

Section 176.63

Section 176.63 sets forth and describes the basic physical requirements for authorized stowage locations of hazardous materials on board vessels. PHMSA is amending paragraph (f)(2) by removing reference to the specific year of SOLAS, Chapter II-2/Regulation 19 (i.e., 1974, as amended) for consistency with the manner in which IBR material is indicated throughout the HMR in outlying sections.

Section 176.76

Section 176.76 prescribes certain requirements for transport vehicles, freight containers, and portable tanks containing hazardous materials transported by vessel. In this final rule, we are revising paragraph (a)(9) to require that when security devices, beacons or other tracking or monitoring equipment are used, they must be securely installed and must be of a certified safe type for the hazardous materials that will be carried within the freight container or transport vehicle.

Section 176.84

Section 176.84 outlines additional requirements for stowage and segregation of hazardous materials transported by cargo and passenger vessels. In this final rule, PHMSA is removing the redundant stowage code 143. This provision is currently assigned to UN1259, UN2845, UN3194, UN3392, and UN3394, and prohibits the carriage of the materials aboard a vessel transporting Class 1 (explosive) material (except for explosives of Division 1.4S). See Section 172.101 Hazardous Materials Table for the amendment that adds stowage code 78 to the above materials of extreme flammability. Such materials are now required to be “separated longitudinally by an intervening complete compartment or hold from explosives” based on amendments adopted in the IMDG Code.

Section 176.142

Section 176.142 prescribes the requirements for hazardous materials of extreme flammability transported on the same vessel as Class 1 (explosive) materials. In this final rule, PHMSA is deleting this section as the restriction no longer exists. Hazardous materials of extreme flammability are no longer prohibited from stowage on the same vessel as explosives. For entries previously affected by this section, the most restrictive stowage requirements are required.

Section 176.905

Section 176.905 prescribes specific requirements for motor vehicles or mechanical equipment powered by internal combustion engines that are offered for transportation and transported by vessel. For consistency with Amendment 35-10 of the IMDG Code, PHMSA is removing the signage requirement for such articles in paragraph (a)(5) and the ignition key removal provisions from paragraph (a)(6). Additionally, we are revising this section to account for modern designs of vehicles and equipment that are powered by engines other than internal combustion engines (e.g., electric engines powered by a fuel cell, hybrid vehicles). We are revising this section to include language applicable to address these new designs. We did not propose these changes in the August 24, 2010 NPRM, but we do not believe including language to account for new designs imposes new restrictions or any greater burdens than currently in the regulations.

Part 178

Section 178.71

Section 178.71 establishes the specifications for UN pressure receptacles. In this final rule, PHMSA is adopting the regulatory relief proposed in Docket HM-218F (75 FR 60017, 75 FR 60017) by revising the requirements in paragraph (c)(1) to allow the use of a proof pressure test in addition to the volumetric expansion test. The ISO 7866 and 9809 standards permit either the proof pressure test or volumetric expansion test to be used. The volumetric expansion test measures the cylinder's elastic expansion and assures the cylinder received a proper heat treatment. However, the ISO standards also require each cylinder be subjected to a hardness test and a comprehensive shear wave ultrasonic examination (UE). PHMSA believes the combination of the proof pressure test, hardness test, and UE should provide adequate assurance that each cylinder received a proper heat treatment. This limitation (i.e., volumetric expansion test only) is also removed from the test pressure marking requirement in the redesignated paragraph (p)(6).

In this final rule, PHMSA is also amending the cylinder bundle marking requirements in § 178.71(e) by adding a new paragraph (e)(8) specifying that pressure vessel markings only apply to the pressure vessel itself and not to the assembly structure of the bundle. Additionally, we are adding new paragraphs (f) and (m) that establish the design and construction requirements for UN metal hydride storage systems and refillable welded cylinders, respectively. To accomplish this, we are redesignating paragraphs (m) through (r) as paragraphs (n) through (s), and revising paragraphs (q) and (s) accordingly to correct paragraph references. Further, we are adding three ISO standards to the IBR table in § 171.7 of the HMR for UN refillable welded cylinders (ISO 4706, 18172-1 and 20703). Lastly, we are requiring that transportable metal hydride storage systems (see § 173.311) be designed, constructed, initially inspected and tested in accordance with ISO 16111:2008, “Transportable gas storage devices—Hydrogen absorbed in reversible metal hydride,” as authorized under § 178.71(m).

Section 178.275

Section 178.275 prescribes requirements for UN portable tanks intended for transportation of liquid and solid hazardous materials. Section 178.275(h) prohibits the use of fusible elements on portable tanks with a test pressure which exceeds 2.65 bar (265 kPa). In § 172.102(c)(8), we are adding a new portable tank special provision TP36 authorizing the use of fusible elements in the vapor space of portable tanks with a gauge test pressure that exceeds 265 kPa (38.4 psig/2.65 bar) for certain organometallic substances. In this final rule, we are authorizing use of fusible elements based on a well-established history of safe transportation of these substances in portable tanks equipped with fusible elements capable of properly functioning at pressure of at least 1,000 kPa (145 psig/10 bar). Past experience of the use of fusible elements indicates reliability and a proper functioning even in the event of a release during loading or unloading. Additionally, for organometallic materials that are shipped in rigid portable tanks with a minimum test pressure of more than 265 kPa (38.4 psig/2.65 bar), the tanks are required to be equipped with a depressurizing system that releases the inside pressure to avoid rupturing the tank as a result of an inadvertent release or fire. Fusible elements are used by shippers as a secondary pressure relief device, in addition to a re-closing pressure relief device. Therefore, we are revising § 178.275(h) to reference special provision TP36 authorizing the use of fusible elements in the vapor space of a portable tank used for the transport of certain organometallic materials.

Section 178.347-1

Section 178.347-1 prescribes the general requirements for DOT Specification 407 cargo tank motor vehicles. Paragraph (d)(9) prescribes weld integrity, compliance and acceptance criteria for bulkheads.

The exception in § 178.347-1(d)(8) currently provides an unconditional exception from UW-12 for all joints. Section 178.347-1(d)(9) applies a condition to one particular joint configuration in a head. In petition P-1333, TTMA requested that we adopt a weld joint efficiency of 0.85 for head seams in bulkheads on DOT 407 cargo tanks. Based on review of the TTMA petition and additional information that was provided, we proposed in the HM-213 NPRM (66 FR 63095, December 4, 2001) that the strength of a weld seam in a bulkhead without radiographic examination of the weld must be 0.85 of the strength of the bulkhead. The welded seam must be a full penetration butt weld, no more than one seam may be used per bulkhead, and the welded seam must be completed before forming the dish radius and knuckle radius.

TTMA commented on the proposal stating, “[w]hile we agree with the proposal to allow a provisional 85% weld joint efficiency for DOT 407 heads with butt-welded seams, we would like to see the requirements of UW-12 of the ASME Code specifically exempted for this welded joint. Even though this section implies an exemption, the exemption is not specific. We suggest the following wording, “[t]he strength of a weld seam in a bulkhead that has not been radiographically examined shall be 0.85 of the strength of the bulkhead and be exempted from the requirements of UW-12 of the ASME Code under the following condition”.

In the HM-213 final rule, we agreed with TTMA's comment and agreed to make the change though the change occurred in a corrections document (68 FR 52363, September 3, 2003). The final rule stated: “[I]n its comments to the NPRM, TTMA agrees with the provisional 85% weld joint efficiency for DOT 407 heads with butt-welded seams. However, TTMA suggests that we include the requirements of Part UW-12 of the ASME Code to the list of excepted requirements in § 178.347-1(d)(8). We agree with TTMA. In this final rule, we are adding Part UW-12 of the ASME Code to the list of excepted requirements.”

In October 2004, we added an exception from the radiography/joint efficiency requirements of ASME VIII section UW-12 for DOT 407 cargo tanks with MAWP of 35 psig and less in § 178.347-1(d)(8) and (9). The intent was to provide a conditional alternate means of determining a joint efficiency for certain head welds. Listing UW-12 in § 178.347-1(d)(8) instead of (9), however, results in an unconditional exception from UW-12 in all welds on these tanks. Therefore, because we believe the revision is appropriate, we are revising § 178.347-1(d)(9), as proposed, by adding a new subparagraph (i) and renumbering the section accordingly.

Section 178.603

Section 178.603 prescribes the drop test requirements for non-bulk packagings in the HMR. In this final rule, PHMSA is revising paragraph (f)(4) to amend the criteria for passing the tests. The HMR require only that there is no leakage of filling substance from the inner packaging. In this final rule, we are also requiring that inner receptacles, inner packagings and articles remain completely within the outer package when drop tested.

Section 178.703

Section 178.703 prescribes the marking requirements for IBCs. PHMSA is aligning paragraph (a)(1)(viii) with the UN Model Regulations by requiring the gross mass, in kilograms, to be marked on all IBC types. The HMR require a net mass to be marked on flexible IBCs which is inconsistent with international standards. PHMSA inadvertently did not revise the HMR under a previous harmonization rulemaking when the international standards were amended to specify that a maximum permissible gross mass be marked on all IBC types.

Section 178.955

Section 178.955 establishes definitions used with regard to subpart Q of part 178, which prescribes the design and testing criteria for Large Packagings. PHMSA is adding the following two new definitions, “Remanufactured Large Packaging” and “Reused Large Packaging,” in new paragraphs (c)(6) and (c)(7), respectively. A “remanufactured” large packaging is defined as a metal or rigid plastic large packaging that is produced as a UN type from a non-UN type or is converted from one UN design type to another UN design type. Remanufactured large packagings are subject to the same HMR requirements that apply to a new large packaging. A “reused” large packaging is defined as a large packaging to be refilled that has been examined and found free of defects affecting the ability to withstand the performance tests. The term includes those that are refilled with the same or similar compatible contents and are transported within distribution chains controlled by the consignor of the product.

Part 180

Section 180.207

Section 180.207 prescribes the requirements for the requalification of UN pressure receptacles. In this final rule, PHMSA is requiring that metal hydride storage systems be requalified every five years in accordance with ISO 16111:2008 and that the records of that requalification be retained in accordance with § 180.215 of the HMR.

Section 180.350

Section 180.350 prescribes applicability and defines certain terms regarding the qualification and maintenance of IBCs. PHMSA is revising paragraph (b) to indicate that the replacement of the inner receptacle of a composite IBC with one from the original manufacturer is considered a repair. This revision is consistent with the recent change in the definition of “repair” in the UN Model Regulations.

V. Regulatory Analyses and Notices

A. Statutory/legal Authority for This Rulemaking

This final rule is published under the following statutory authorities:

1. 49 U.S.C. 5103(b) authorizes the Secretary of Transportation to prescribe regulations for the safe transportation, including security, of hazardous materials in intrastate, interstate, and foreign commerce. This final rule amends regulations to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations and vessel stowage requirements. To this end, as discussed in detail above, the final rule amends the HMR to more fully align them with the biennial updates of the UN Model Regulations, the IMDG Code and the ICAO TI.

Harmonization serves to facilitate international commerce. At the same time, harmonization promotes the safety of people, property, and the environment by reducing the potential for confusion and misunderstanding that could result if shippers and transporters were required to comply with two or more conflicting sets of regulatory requirements. While the intent of this rulemaking is to align the HMR with international standards, we review and consider each amendment on its own merit based on its overall impact on transportation safety and the economic implications associated with its adoption into the HMR. Our goal is to harmonize without sacrificing the current HMR level of safety and without imposing undue burdens on the regulated public. Thus, as explained in the corresponding sections above, we are not harmonizing with certain specific provisions of the UN Model Regulations, the IMDG Code, and the ICAO TI. Moreover, we are maintaining a number of current exceptions for domestic transportation that should minimize the compliance burden on the regulated community.

2. 49 U.S.C. 5120(b) authorizes the Secretary of Transportation to ensure that, to the extent practicable, regulations governing the transportation of hazardous materials in commerce are consistent with standards adopted by international authorities. This rule amends the HMR to maintain alignment with international standards by incorporating various amendments to facilitate the transport of hazardous material in international commerce. To this end, as discussed in detail above, PHMSA incorporates changes into the HMR based on the sixteenth revised edition of the UN Model Regulations and the 2011-2012 ICAO Technical Instructions, which become effective January 1, 2011, and Amendment 35-10 to the IMDG Code which becomes effective January 1, 2012. The continually increasing amount of hazardous materials transported in international commerce warrants the harmonization of domestic and international requirements to the greatest extent possible.

B. Executive Order 12866 and DOT Regulatory Policies and Procedures

This final rule is not considered a significant regulatory action under section 3(f) of Executive Order 12866 and, therefore, was not reviewed by the Office of Management and Budget. The final rule is not considered a significant rule under the Regulatory Policies and Procedures of the Department of Transportation (44 FR 11034). This final rule applies to offerors and carriers of hazardous materials, such as chemical manufacturers, chemical users and suppliers, packaging manufacturers, distributors, radiopharmaceutical companies, and training companies. Benefits resulting from the adoption of the amendments in this final rule include enhanced transportation safety resulting from the consistency of domestic and international hazard communications and continued access to foreign markets by U.S. manufacturers of hazardous materials.

The majority of amendments in this final rule should result in cost savings and ease the regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America.

We authorize a one year transition period to allow for training of employees and to ease any burden on entities affected by the amendments. The total net increase in costs to businesses in implementing the final rule is considered to be minimal. Initial start-up and inventory costs will result from these changes. However, the costs are offset by greater long term savings of conformance with one set of regulations and a one-year transition period. A regulatory evaluation is available for review in the public docket for this rulemaking.

C. Executive Order 13132

This final rule has been analyzed in accordance with the principles and criteria contained in Executive Order 13132 (“Federalism”). This final rule preempts 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. 5101-5128, contains an express preemption provision (49 U.S.C. 5125(b)) that preempts State, local and Indian Tribe requirements on certain covered subjects, as follows:

(1) The designation, description, and classification of hazardous material;

(2) The packing, repacking, handling, labeling, marking, and placarding of hazardous material;

(3) The preparation, execution, and use of shipping documents related to hazardous material and requirements related to the number, contents, and placement of those documents;

(4) The written notification, recording, and reporting of the unintentional release in transportation of hazardous material; and

(5) The design, manufacture, fabrication, inspection, marking, maintenance, recondition, repair, or testing of a packaging or container represented, marked, certified, or sold as qualified for use in transporting hazardous material in commerce.

This final rule addresses covered subject items (1), (2), (3), (4) and (5) above and preempts State, local, and Indian Tribe requirements not meeting the “substantively the same” standard. This final rule is necessary to incorporate changes adopted in international standards, effective January 1, 2011. If the changes in this final rule are not adopted into the HMR, U.S. companies, including numerous small entities competing in foreign markets, would be at an economic disadvantage. These companies would be forced to comply with a dual system of regulations. The changes in this final rulemaking are intended to avoid this result. Federal hazardous materials transportation law provides at 49 U.S.C. 5125(b)(2) that, if DOT issues a regulation concerning any of the covered subjects, DOT must determine and publish in the Federal Register the effective date of Federal preemption. The effective date of Federal preemption is 90 days from publication of the final rule in this matter.

D. Executive Order 13175

This final rule was 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, does not impose substantial direct compliance costs, and is required by statute, the funding and consultation requirements of Executive Order 13175 do not apply.

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

The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an agency to review regulations to assess their impact on small entities, unless the agency determines that a rule is not expected to have a significant impact on a substantial number of small entities. This final rule facilitates the transportation of hazardous materials in international commerce by providing consistency with international standards. This final rule applies to offerors and carriers of hazardous materials, some of whom are small entities, such as chemical manufacturers, users and suppliers, packaging manufacturers, distributors and training companies. As discussed above, under Executive Order 12866, the majority of amendments in this final rule should result in cost savings and ease the regulatory compliance burden for shippers engaged in domestic and international commerce, including trans-border shipments within North America.

Many companies will realize economic benefits as a result of these amendments. Additionally, the changes effected by this final rule will relieve U.S. companies, including small entities competing in foreign markets, from the burden of complying with a dual system of regulations. Therefore, I certify that these amendments will not, if promulgated, 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 approved information collections under Office of Management and Budget (OMB) Control Number 2137-0034, “Hazardous Materials Shipping Papers and Emergency Response Information,” with an expiration date of May 31, 2011, and OMB Control Number 2137-0557, “Approvals for Hazardous Materials,” with an expiration date of June 30, 2011. This final rule may result in a decrease in the annual burden and costs of OMB Control Number 2137-0034 due to amendments to the exceptions for shipping paper requirements for limited quantities of Class 3, Division 4.1, Division 4.2, Division 4.3, Division 5.1, Division 5.2, Division 6.1, Class 8, and Class 9 materials for those limited quantities that are defined as consumer commodities. This final rule may result in an increase in the annual burden and costs of OMB Control Number 2137-0557 due to amendments to the classification criteria for eight Division 1.4 explosive articles to add the Type 6(d) test as prescribed in the fifth revised edition of the UN Manual of Tests and Criteria.

Under the Paperwork Reduction Act of 1995, no person is required to respond to an information collection unless it has been approved by OMB and displays a valid OMB control number. Section 1320.8(d), Title 5, Code of Federal Regulations requires that PHMSA provide interested members of the public and affected agencies an opportunity to comment on information and recordkeeping requests.

This final rule identifies revised information collection requests that PHMSA will submit to OMB for approval based on the requirements in this final rule. PHMSA has developed burden estimates to reflect changes in this final rule, and estimates the information collection and recordkeeping burden as proposed in this rule to be as follows:

OMB Control No.	2137-0034
Annual Decrease in Number of Respondents	75,000,000
Annual Decrease in Annual Number of Responses	75,000,000
Annual Decrease in Annual Burden Hours	1,875,000
Annual Decrease in Annual Burden Costs	$1,875,000.00
OMB Control No.	2137-0557
Annual Increase in Number of Respondents	465
Annual Increase in Annual Number of Responses	465
Annual Increase in Annual Burden Hours	2,325
Annual Increase in Annual Burden Costs	$58,125

PHMSA will submit the revised information collection and recordkeeping requirements to OMB for approval.

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 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 $141.3 million or more, adjusted for inflation, to either State, local or Tribal governments, in the aggregate, or to the private sector in any one year, and is the least burdensome alternative that achieves the objective of the rule.

I. Environmental Assessment

The National Environmental Policy Act, 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. The Council on Environmental Quality (CEQ) regulations order Federal agencies to conduct an environmental review considering (1) the need for the proposed action, (2) alternatives to the proposed action, (3) probable environmental impacts of the proposed action and alternatives, and (4) the agencies and persons consulted during the consideration process. 40 CFR 1508.9(b).

1. Purpose and Need

PHMSA proposed to amend the Hazardous Materials Regulations to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. These revisions are necessary to harmonize the Hazardous Materials Regulations with recent changes to the International Maritime Dangerous Goods Code, the International Civil Aviation Organization's Technical Instructions for the Transport of Dangerous Goods by Air, and the United Nations Recommendations on the Transport of Dangerous Goods. The amendments are intended to enhance the safety 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 effective emergency response in the event of a hazardous materials incident.

The HMR regulate materials that meet the definition of a marine pollutant in all modes of transportation. The intended effect is to increase the level of safety associated with the transportation of substances hazardous to the marine environment by way of improved communication of their presence in transportation and establishing appropriate requirements for their packaging. The HMR uses a list-based system designed to help shippers determine if a material meets the definition of a marine pollutant. Recently, the IMO adopted a criteria based system for identification of materials hazardous to the marine environment based on the Globally Harmonized System of Classification and Labeling of Chemicals (GHS).

2. Alternatives

In developing this proposed rule, we considered three alternatives:

(1) Do nothing.

(2) Adopt the international standards in their entirety.

(3) Adopt most of the international standards, with certain modifications based on safety or economic considerations.

Alternative 1: Because our goal is to facilitate uniformity, compliance, commerce and safety in the transportation of hazardous materials, we rejected this alternative.

Alternative 2: By adopting the international standards in their entirety, PHMSA could potentially adopt provisions that, in our view, do not provide an adequate safety level. Further, because we provide for domestic exceptions and extended compliance periods to minimize the potential economic impact of any revisions on the regulated community, this alternative was also rejected.

Alternative 3: Consistency between U.S. and international regulations helps to assure the safety 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 effective emergency response in the event of a hazardous materials incident. Under Alternative 3, we would harmonize the HMR with international standards to the extent consistent with U.S. safety and economic goals.

Alternative 3 is the only alternative that addresses, in all respects, the purpose of this regulatory action, which is to facilitate the safe and efficient transportation of hazardous materials in international commerce. These actions will provide the greatest possible harmonization with international requirements without posing an undue increased cost burden on industry. For these reasons, Alternative 3 is our recommended alternative.

3. Analysis of Environmental Impacts

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, or loading, unloading, or handling problems. The ecosystems that could be affected by a release include air, water, soil, and ecological resources (e.g., wildlife habitats). The adverse environmental impacts associated with releases of most hazardous materials are short-term impacts that can be greatly reduced or eliminated through prompt clean-up of the accident scene. Most hazardous materials are not transported in quantities sufficient to cause significant, long-term environmental damage if they are released.

The hazardous material regulatory system is a risk-management system that is prevention-oriented and focused on identifying hazards and reducing the probability and quantity of a hazardous material release. Amending the HMR to maintain alignment with international standards enhances the safe transportation of hazardous materials in domestic and international commerce. When considering the adoption of international standards under the HMR, we review and consider each amendment on its own merit and assess its impact on transportation safety and the environment. Based on the lack of public comment on the issue, it is our conclusion that the amendments adopted in this final rule will have no adverse affect on the environment.

4. Consultations and Public Comment

On June 20, 2007, November 27, 2007, June 18, 2008, and November 19, 2008, PHMSA hosted public meetings with public and private stakeholders to discuss draft U.S. positions on the United Nation's Sub-Committee of Experts on the Transport of Dangerous Goods (UNSCOE) proposals for the sixteenth revised edition of the UN Recommendations on the Transport of Dangerous Goods Model Regulations. In addition, PHMSA and the U.S. Coast Guard hosted a public meeting on September 17, 2008, and hosted a second meeting on September 10, 2009, to discuss amendments to the IMDG Code. A public meeting was held on September 29, 2009 to discuss amendments to the ICAO Technical Instructions. During these public meetings, U.S. positions on proposed amendments to the UN Recommendations were considered and discussed. Positions were established based on input received during these meetings in conjunction with internal review, including thorough technical review.

We have identified a number of immediate and long-term actions that participants in the international community are taking or will take to enhance the safe transportation of hazardous materials. Through this integrated and cooperative approach, we believe we can be most successful in reducing incidents, enhancing safety, and protecting the public.

J. Privacy Act

Anyone is able to search the electronic form of any written communications and comments received into any of our dockets by the name of the individual submitting the document (or signing the document, if submitted on behalf of an association, business, labor union, etc.). You may review DOT's complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477) or you may visit http://www.dot.gov/​privacy.html.

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. For purposes of these requirements, Federal agencies may participate in the establishment of international standards, so long as the standards have a legitimate domestic objective, such as providing for safety, and do not operate to exclude imports that meet this objective. The statute also requires consideration of international standards and, where appropriate, that they be the basis for U.S. standards. PHMSA participates in the establishment of international standards to protect the safety of the American public, and we have assessed the effects of the proposed rule to ensure that it does not exclude imports that meet this objective. Accordingly, this rulemaking is consistent with PHMSA's obligations under the Trade Agreement Act, as amended.

3. In § 171.8, the definitions for “Metal hydride storage system” and “Open cryogenic receptacle” are added and the definitions for “Oxidizing gas” and “UN Recommendations” are revised to read as follows:

§ 171.8

Definitions and abbreviations.

* * * * *

Metal hydride storage system means a single complete hydrogen storage system that includes a receptacle, metal hydride, pressure relief device, shut-off valve, service equipment and internal components used for the transportation of hydrogen only.

* * * * *

Open cryogenic receptacle means a transportable thermally insulated receptacle for refrigerated liquefied gases maintained at atmospheric pressure by continuous venting of the refrigerated gas.

* * * * *

Oxidizing gas means a gas that may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does. Specifically, this means a pure gas or gas mixture with an oxidizing power greater than 23.5% as determined by a method specified in ISO 10156: or 10156-2: (IBR, see § 171.7 of this subchapter) (see also § 173.115(k)).

* * * * *

U.N. Recommendations means the U.N. Recommendations on the Transport of Dangerous Goods, Model Regulations (IBR, see § 171.7 of this subchapter).

* * * * *

§ 171.23

[Amended]

4. In § 171.23, paragraph (b)(9) is removed and reserved.

5. In § 171.25, the first sentence in paragraph (b)(1) is revised, paragraph (b)(4) is added, and paragraphs (c)(5) and (d)(3) are removed.

The revision and addition read as follows:

§ 171.25

Additional requirements for the use of the IMDG Code.

* * * * *

(b) * * *

(1) Unless specified otherwise in this subchapter, a shipment must conform to the requirements in part 176 of this subchapter. * * *

* * * * *

(4) Material consigned under UN3166 and UN3171 (e.g., Engines, internal combustion, etc., Vehicles, etc. and Battery-powered equipment) may be prepared in accordance with the IMDG Code or this subchapter.

* * * * *

PART 172—HAZARDOUS MATERIALS TABLE, SPECIAL PROVISIONS, HAZARDOUS MATERIALS COMMUNICATIONS, EMERGENCY RESPONSE INFORMATION, TRAINING REQUIREMENTS, AND SECURITY PLANS

6. The authority citation for part 172 continues to read as follows:

Authority: 49 U.S.C. 5101-5128; 44701; 49 CFR 1.53.

7. In § 172.101, the following amendments are made:

a. Paragraph (c)(10)(i) is revised;

b. Paragraph (e) is amended by adding a sentence at the end of the paragraph; and

c. The Hazardous Materials Table is amended by removing those entries under [REMOVE], adding entries under [ADD], and revising entries under [REVISE] as shown below.

The revisions and additions read as follows:

§ 172.101

Purpose and use of hazardous materials table.

* * * * *

(c) * * *

(10) * * *

(i) A mixture or solution not identified specifically by name, comprised of a single predominant hazardous material identified in the Table by technical name and one or more hazardous and/or non-hazardous material, must be described using the proper shipping name of the hazardous material and the qualifying word “mixture” or “solution”, as appropriate, unless—

(A) Except as provided in § 172.101(i)(4) the packaging specified in Column 8 is inappropriate to the physical state of the material;

(B) The shipping description indicates that the proper shipping name applies only to the pure or technically pure hazardous material;

(C) The hazard class, packing group, or subsidiary hazard of the mixture or solution is different from that specified for the entry;

(D) There is a significant change in the measures to be taken in emergencies;

(E) The material is identified by special provision in Column 7 of the § 172.101 Table as a material poisonous by inhalation; however, it no longer meets the definition of poisonous by inhalation or it falls within a different hazard zone than that specified in the special provision; or

(F) The material can be appropriately described by a shipping name that describes its intended application, such as “Coating solution”, “Extracts, flavoring” or “Compound, cleaning liquid.”

* * * * *

(e) * * * Those preceded by the letters “ID” are associated with proper shipping names recognized by the ICAO Technical Instructions (IBR, see § 171.7 of this subchapter).

The revisions and additions read as follows:

§ 172.102

Special provisions.

* * * * *

(c) * * *

(1) * * *

Code/Special Provisions

* * * * *

15 This entry applies to “Chemical kits” and “First aid kits” containing one or more compatible items of hazardous materials in boxes, cases, etc. that, for example, are used for medical, analytical, diagnostic, testing, or repair purposes. Kits that are carried on board transport vehicles for first aid or operating purposes are not subject to the requirements of this subchapter.

* * * * *

40 Polyester resin kits consist of two components: A base material (Class 3, Packing Group II or III) and an activator (organic peroxide), each separately packed in an inner packaging. The organic peroxide must be type D, E, or F, not requiring temperature control. The components may be placed in the same outer packaging provided they will not interact dangerously in the event of leakage. The Packing Group assigned will be II or III, according to the classification criteria for Class 3, applied to the base material. Additionally, unless otherwise excepted in this subchapter, polyester resin kits must be packaged in specification combination packagings based on the performance level of the base material contained within the kit.

* * * * *

78 This entry may not be used to describe compressed air which contains more than 23.5 percent oxygen. Compressed air containing greater than 23.5 percent oxygen must be shipped using the description “Compressed gas, oxidizing, n.o.s., UN3156.”

* * * * *

110 Fire extinguishers transported under UN1044 and oxygen cylinders transported for emergency use under UN1072 may include installed actuating cartridges (cartridges, power device of Division 1.4C or 1.4S), without changing the classification of Division 2.2, provided the aggregate quantity of deflagrating (propellant) explosives does not exceed 3.2 grams per cylinder. Oxygen cylinders with installed actuating cartridges as prepared for transportation must have an effective means of preventing inadvertent activation.

* * * * *

130 “Batteries, dry, sealed, n.o.s.,” commonly referred to as dry batteries, are hermetically sealed and generally utilize metals (other than lead) and/or carbon as electrodes. These batteries are typically used for portable power applications. The rechargeable (and some non-rechargeable) types have gelled alkaline electrolytes (rather than acidic) making it difficult for them to generate hydrogen or oxygen when overcharged and therefore, differentiating them from non-spillable batteries. Dry batteries specifically covered by another entry in the § 172.101 Table must be transported in accordance with the requirements applicable to that entry. For example, nickel-metal hydride batteries transported by vessel in certain quantities are covered by another entry (see Batteries, nickel-metal hydride, UN3496). Dry batteries not specifically covered by another entry in the § 172.101 Table are covered by this entry (i.e., Batteries, dry, sealed, n.o.s.) and are not subject to requirements of this subchapter except for the following:

(a) Incident reporting. For transportation by aircraft, a telephone report in accordance with § 171.15(a) is required if a fire, violent rupture, explosion or dangerous evolution of heat (i.e., an amount of heat sufficient to be dangerous to packaging or personal safety to include charring of packaging, melting of packaging, scorching of packaging, or other evidence) occurs as a direct result of a dry battery. For all modes of transportation, a written report submitted, retained, and updated in accordance with § 171.16 is required if a fire, violent rupture, explosion or dangerous evolution of heat occurs as a direct result of a dry battery or battery-powered device.

(b) Preparation for transport. Batteries and battery-powered device(s) containing batteries must be prepared and packaged for transport in a manner to prevent:

(1) A dangerous evolution of heat;

(2) Short circuits, including but not limited to the following methods:

(i) Packaging each battery or each battery-powered device when practicable, in fully enclosed inner packagings made of non-conductive material;

(ii) Separating or packaging batteries in a manner to prevent contact with other batteries, devices or conductive materials (e.g., metal) in the packagings; or

(iii) Ensuring exposed terminals or connectors are protected with non-conductive caps, non-conductive tape, or by other appropriate means; and

(3) Damage to terminals. If not impact resistant, the outer packaging should not be used as the sole means of protecting the battery terminals from damage or short circuiting. Batteries must be securely cushioned and packed to prevent shifting which could loosen terminal caps or reorient the terminals to produce short circuits. Batteries contained in devices must be securely installed. Terminal protection methods include but are not limited to the following:

(i) Securely attaching covers of sufficient strength to protect the terminals;

(ii) Packaging the battery in a rigid plastic packaging; or

(iii) Constructing the battery with terminals that are recessed or otherwise protected so that the terminals will not be subjected to damage if the package is dropped.

(c) Additional air transport requirements. For a battery whose voltage (electrical potential) exceeds 9 volts—

(1) When contained in a device, the device must be packaged in a manner that prevents unintentional activation or must have an independent means of preventing unintentional activation (e.g., packaging restricts access to activation switch, switch caps or locks, recessed switches, trigger locks, temperature sensitive circuit breakers, etc.); and

(2) An indication of compliance with this special provision must be provided by marking each package with the words “not restricted” or by including the words “not restricted” on a transport document such as an air waybill accompanying the shipment.

(d) Used or spent battery exception. Used or spent dry batteries of both non-rechargeable and rechargeable designs, with a marked rating up to 9-volt that are combined in the same package and transported by highway or rail for recycling, reconditioning, or disposal are not subject to this special provision or any other requirement of the HMR. Note that batteries utilizing different chemistries (i.e., those battery chemistries specifically covered by another entry in the § 172.101 Table) as well as dry batteries with a marked rating greater than 9-volt may not be combined with used or spent batteries in the same package. Note also that this exception does not apply to batteries that have been reconditioned for reuse.

* * * * *

134 This entry only applies to vehicles, machinery and equipment powered by wet batteries, sodium batteries, or lithium batteries that are transported with these batteries installed. Examples of such items are electrically-powered cars, lawn mowers, wheelchairs, and other mobility aids. Self-propelled vehicles or equipment that also contain an internal combustion engine must be consigned under the entry “Engine, internal combustion, flammable gas powered” or “Engine, internal combustion, flammable liquid powered” or “Vehicle, flammable gas powered” or “Vehicle, flammable liquid powered,” as appropriate. These entries include hybrid electric vehicles powered by both an internal combustion engine and batteries. Additionally, self-propelled vehicles or equipment that contain a fuel cell engine must be consigned under the entries “Engine, fuel cell, flammable gas powered” or “Engine, fuel cell, flammable liquid powered” or “Vehicle, fuel cell, flammable gas powered” or “Vehicle, fuel cell, flammable liquid powered,” as appropriate. These entries include hybrid electric vehicles powered by a fuel cell engine, an internal combustion engine, and batteries.

135 Internal combustion engines installed in a vehicle must be consigned under the entries “Vehicle, flammable gas powered” or “Vehicle, flammable liquid powered,” as appropriate. These entries include hybrid electric vehicles powered by both an internal combustion engine and wet, sodium or lithium batteries installed. If a fuel cell engine is installed in a vehicle, the vehicle must be consigned using the entries “Vehicle, fuel cell, flammable gas powered” or “Vehicle, fuel cell, flammable liquid powered,” as appropriate. These entries include hybrid electric vehicles powered by a fuel cell, an internal combustion engine, and wet, sodium or lithium batteries installed.

71. The authority citation for part 178 continues to read as follows:

Authority: 49 U.S.C. 5101-5128; 49 CFR 1.53.

72. Section 178.71 is revised to read as follows:

§ 178.71

Specifications for UN pressure receptacles.

(a) General. Each UN pressure receptacle must meet the requirements of this section. Requirements for approval, qualification, maintenance, and testing are contained in § 178.70, and subpart C of part 180 of this subchapter.

(b) Definitions. The following definitions apply for the purposes of design and construction of UN pressure receptacles under this subpart:

Alternative arrangement means an approval granted by the Associate Administrator for a MEGC that has been designed, constructed or tested to the technical requirements or testing methods other than those specified for UN pressure receptacles in part 178 or part 180 of this subchapter.

Bundle of cylinders. See § 171.8 of this subchapter.

Design type means a pressure receptacle design as specified by a particular pressure receptacle standard.

Design type approval means an overall approval of the manufacturer's quality system and design type of each pressure receptacle to be produced within the manufacturer's facility.

UN tube. See § 171.8 of this subchapter.

(c) General design and construction. UN pressure receptacles and their closures must be designed, manufactured, tested and equipped in accordance with the requirements contained in this section. The ISO standard requirements applicable to UN pressure receptacles may be varied only if approved in writing by the Associate Administrator.

(d) Service equipment. (1) Except for pressure relief devices, UN pressure receptacle equipment, including valves, piping, fittings, and other equipment subjected to pressure must be designed and constructed to withstand at least 1.5 times the test pressure of the pressure receptacle.

(2) Service equipment must be configured or designed to prevent damage that could result in the release of the pressure receptacle contents during normal conditions of handling and transport. Manifold piping leading to shut-off valves must be sufficiently flexible to protect the valves and the piping from shearing or releasing the pressure receptacle contents. The filling and discharge valves and any protective caps must be secured against unintended opening. The valves must conform to ISO 10297 (IBR, see § 171.7 of this subchapter) and be protected as specified in § 173.301b(f) of this subchapter.

(3) UN pressure receptacles that cannot be handled manually or rolled, must be equipped with devices (e.g., skids, rings, straps) ensuring that they can be safely handled by mechanical means and so arranged as not to impair the strength of, nor cause undue stresses, in the pressure receptacle.

(4) Pressure receptacles filled by volume must be equipped with a level indicator.

(e) Bundles of cylinders. UN pressure receptacles assembled in bundles must be structurally supported and held together as a unit and secured in a manner that prevents movement in relation to the structural assembly and movement that would result in the concentration of harmful local stresses. The frame design must ensure stability under normal operating conditions.

(1) The frame must securely retain all the components of the bundle and must protect them from damage during conditions normally incident to transportation. The method of cylinder restraint must prevent any vertical or horizontal movement or rotation of the cylinder that could cause undue strain on the manifold. The total assembly must be able to withstand rough handling, including being dropped or overturned.

(2) The frame must include features designed for the handling and transportation of the bundle. The lifting rings must be designed to withstand a design load of 2 times the maximum gross weight. Bundles with more than one lifting ring must be designed such that a minimum sling angle of 45 degrees to the horizontal can be achieved during lifting using the lifting rings. If four lifting rings are used, their design must be strong enough to allow the bundle to be lifted by two rings. Where two or four lifting rings are used, diametrically opposite lifting rings must be aligned with each other to allow for correct lifting using shackle pins. If the bundle is filled with forklift pockets, it must contain two forklift pockets on each side from which it is to be lifted. The forklift pockets must be positioned symmetrically consistent with the bundle center of gravity.

(3) The frame structural members must be designed for a vertical load of 2 times the maximum gross weight of the bundle. Design stress levels may not exceed 0.9 times the yield strength of the material.

(4) The frame must not contain any protrusions from the exterior frame structure that could cause a hazardous condition.

(5) The frame design must prevent collection of water or other debris that would increase the tare weight of bundles filled by weight.

(6) The floor of the bundle frame must not buckle during normal operating conditions and must allow for the drainage of water and debris from around the base of the cylinders.

(7) If the frame design includes movable doors or covers, they must be capable of being secured with latches or other means that will not become dislodged by operational impact loads. Valves that need to be operated in normal service or in an emergency must be accessible.

(8) For bundles of cylinders, pressure receptacle marking requirements only apply to the individual cylinders of a bundle and not to any assembly structure.
