AGENCY:

Pipeline and Hazardous Materials Safety Administration (PHMSA), DOT.

ACTION:

Final rule.

SUMMARY:

This final rule corrects editorial errors, makes minor regulatory changes and, in response to requests for clarification, improves the clarity of certain provisions in the Hazardous Materials Regulations (HMR). The intended effect of this rule is to enhance the accuracy and reduce misunderstandings of the regulations. The amendments contained in this rule are non-substantive changes.

DATES:

Effective date: October 1, 2008.

FOR FURTHER INFORMATION CONTACT:

SUPPLEMENTARY INFORMATION:

I. Background

PHMSA annually reviews the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180) to identify typographical and other errors, outdated addresses or other contact information, and similar errors. In this final rule, we are correcting typographical errors; incorrect CFR references and citations; an incorrect address; inaccurate office names; inconsistent use of terminology; misstatements of certain regulatory requirements; and inadvertent omissions of information. In addition, this final rule revises the address for PHMSA to indicate the new location for the headquarters office. Because these amendments do not impose new requirements, notice and public comment procedures are unnecessary. By making these amendments effective without the customary 30-day delay following publication, the changes will appear in the next revision of Title 49.

II. Section by Section Review

The following is a summary by section of the major changes made in this final rule. The summary does not include minor editorial corrections such as punctuation errors, or similar minor revisions.

Part 171

Section 171.3

This section prescribes requirements for transporting hazardous waste under the HMR. Paragraph (b)(1) requires each motor vehicle to be marked in accordance with 49 CFR 390.21 and 1058.2. Because § 1058.2 no longer exists, in this final rule we are removing this reference in paragraph (b)(1).

Section 171.7

Paragraph (a) of § 171.7 lists materials incorporated by reference into the HMR. In paragraph (a)(3), we are correcting the mailing address for the American Pyrotechnic Association.

Paragraph (b) of § 171.7 lists information materials that are not incorporated by reference. In a final rule published on January 28, 2008 (Docket No. 05-21812 (HM-218D); 73 FR 4699, effective October 1, 2008), we added in paragraph (b) an entry for the Compressed Gas Association's (CGA's) publication, CGA C-1.1 in § 171.7(b). A new paragraph (g)(6) in § 180.205 listed CGA C-1.1 as an example of training material that may be used by persons who requalify cylinders using the volumetric expansion test method. Following the publication of the HM-215D final rule, we received an appeal from Hydro-Test (PHMSA-2005-21812-0025) asking us to either remove this reference to CGA C-1.1 or add examples of other training materials that may be used. Hydro-Test noted that referencing only the CGA publication in the HMR could suggest that other training materials are not acceptable. We added CGA C-1.1 as an example of guidance material that may be used to assist requalifiers in setting up their cylinder training procedures and recordkeeping requirements. The publication is not a stand alone tool for training persons on how to perform requalification of cylinders using the volumetric expansion test method. However, to alleviate confusion for cylinder requalifiers, in this final rule, we are removing the new entry for CGA C-1.1 from § 171.7(b) and paragraph (g)(6) from § 180.205.

Section 171.8

This section contains definitions for terms used in the HMR. We inadvertently omitted replacing the name “Diagnostic specimens” with the name “Biological substances, category B” when we revised the HMR to harmonize its infectious substance requirements with international requirements and removed the name “Diagnostic specimens” under Docket No. PHMSA-2004-16895 (HM-226A; 71 FR 32244, 6/2/06). In this final rule, we are correcting this oversight. Also, we are revising the definitions for “Elevated temperature material” and “Liquid phase” to specify the metric conversion of 100 °F as 38 °C for consistency throughout the HMR and with that specified in the American Society for Testing and Materials (ASTM) Standard ASTM D 4359, “Standard Test Method for Determining Whether a Material is a Liquid or a Solid,” which the HMR incorporates by reference under § 171.7.

Section 171.23

This section prescribes requirements for specific materials and packagings transported under the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions), International Maritime Dangerous Goods Code (IMDG Code), Transport Canada's Transportation of Dangerous Goods Regulations (Transport Canada TDG Regulations), and the International Atomic Energy Agency Regulations for the Safe Transport of Radioactive Material (IAEA Regulations). In this final rule, we are revising paragraph (a)(3)(iii) to correct the reference “(a)(3)” to “(a)(4).”

Section 171.25

This section prescribes additional requirements for the use of the IMDG Code under the HMR. In this final rule, we are correcting several inadvertent errors in this section. In paragraph (b)(1), we are revising the regulatory text to clarify that the segregation requirements in Part 7 of the IMDG Code may be utilized for both rail and highway transportation. The rail mode was inadvertently removed in the printing of the HM-215F final rule published on May 3, 2007. We are also correcting the word “subpart” to read “subchapter” in the second sentence of this paragraph, and the reference to “Part 7, Chapter 2,” of the IMDG Code to read “Part 7, Chapter 7.2” in the last sentence. In paragraph (b)(2), we are clarifying that the paragraph applies to transportation by vessel.

Part 172

In the heading to Part 172, we are adding the words “Security Plans” to reflect the security plan requirements in Subpart I of Part 172.

Section 172.201

This section prescribes requirements on the preparation and retention of shipping papers. Paragraph (a)(1)(iii) is corrected to clarify the use of the letter “X” to identify hazardous materials on a shipping paper. The clarification allows the letter “X” to be placed in a column titled “HM” appearing before the basic shipping description instead of the proper shipping name of a hazardous material to recognize that the identification number may appear first in the basic shipping description as provided in § 172.202(b).

Section 172.202

This section prescribes requirements for shipping descriptions on shipping papers. In paragraphs (a)(5) and (a)(6)(ii), we are inserting the U.S. standard measurement conversions after the metric measurements for clarity.

Section 172.203

This section prescribes additional description requirements for hazardous materials on shipping papers. In this final rule, we are correcting the examples provided in this section as follows:

• We are revising paragraph (c)(2) to reflect in the example the basic shipping description sequence prescribed in § 172.202(b), with the UN identification number appearing first, and to correct the example of the basic description for “Allyl alcohol” to state that this material is a Zone B toxic inhalation hazard.
• We are revising paragraph (d)(1) to correct the spelling of the word “radionuclides” in the second sentence.
• We are revising paragraph (i)(2), which contains additional shipping paper description requirements for flammable liquids transported by vessel, to reflect a flash point at 60 °C (140 °F) in place of 61 °C for consistency with the provisions contained in 49 CFR 173.120(a) and paragraph 5.4.1.4.3 of the IMDG Code.
• Paragraph (k) requires the use of a technical name with a proper shipping name designated as generic with the letter “G” in Column 1 of the § 172.101 Table. We are making a minor editorial revision to the last sentence in paragraph (k) and adding two new sentences to refer readers to the definition of “Technical name” in § 171.8 and to other relevant information in § 172.301.

Section 172.320

This section prescribes the marking requirements for explosive hazardous materials. In paragraph (b), we are correcting the reference to the regulation requiring a product code for commercial explosives from “27 CFR part 55” to read “27 CFR part 555.”

In addition, we are removing current paragraph (e)(4), which contains an expired transitional provision, and redesignating current paragraph (e)(5) as paragraph (e)(4).

Section 172.704

This section prescribes training requirements for hazmat employees. In paragraph (a)(2)(ii), we are revising the reference to “§§ 171.11 and 171.12” to read “authorized by subpart C of part 171 of this subchapter” to be consistent with revisions adopted in the final rule issued under Docket No. PHMSA-2005-24131 (HM-215F, 72 FR 25162, 3/5/07).

Part 173

Section 173.21

This section prescribes the hazardous materials and packages that are forbidden in transportation. In this final rule, we are revising paragraph (f)(3) to clearly state that approvals issued by the Bureau of Explosives are no longer valid.

Section 173.25

This section prescribes requirements for transporting hazardous materials packages in overpacks. In this final rule, we are removing the second sentence in paragraph (a)(4) because it contains an expired compliance date.

Section 173.219

This section prescribes requirements for transporting life-saving appliances and matches. In this final rule, we are amending paragraph (a) by replacing the word “movement” with “shifting” to clarify the devices must be placed in inner packagings that are packed in outer packagings in a manner to prevent the devices from shifting within the outer packaging.

Section 173.227

This section prescribes requirements for packaging poisonous-by-inhalation materials, in Division 6.1, Packing Group I, Hazard Zone B. We are revising paragraph (b) to include UN 6HH1 composite packagings with an inner protective plastic drum. This revision was inadvertently omitted in a final rule issued under Docket No. RSPA-04-17036 (HM-215G, 69 FR 76043, 12/20/04).

Section 173.308

This section sets forth requirements for the transportation of lighters. In this final rule, we are revising paragraph (b)(3)(ii) to specify the metric conversion of 100 °F as 38 °C for consistency throughout the HMR.

Part 175

Section 175.30

This section prescribes requirements for inspecting hazardous materials shipments aboard an aircraft. A capitalization error is corrected in paragraph (a)(2). In paragraph (a)(3), we are revising the reference to § 171.11 to read “as authorized by subpart C of part 171 of this subchapter” to be consistent with the revisions adopted under HM-215F.

Part 176

Section 176.83

This section prescribes segregation requirements for hazardous materials transported by vessel. In this final rule, we are revising paragraph (b) to clarify that although Column 1 of Table § 176.83(b) is titled “Class,” it also lists certain hazard class divisions.

Part 178

Section 178.36

This section contains the design and manufacture requirements for DOT 3A and 3AX seamless steel cylinders. In paragraph (a)(2), we are correcting the wording “seamless stainless steel cylinder” to remove the word stainless, and in the first sentence in paragraph (f), the wording “service pressure less than 900 pounds” to read “service pressure less than 900 psig”.

Section 178.275

This section prescribes design and manufacture standards for UN portable tanks intended for the transportation of liquid and solid hazardous materials. In the HM-215G final rule, paragraph (i)(2), the introductory text was revised to clarify the combined delivery capacity of a UN portable tank's relief system. However, the amendatory language incorrectly stated that paragraph (i)(2) was revised. As a result, all the vent capacity formulas and tables referenced in the paragraph were removed. We are reinstating paragraphs (i)(2)(i)-(iv) in this final rule. In addition, in paragraph (d)(3), the reference to “(c)(2)” is corrected to read “(d)(2).”

Section 178.605

This section prescribes the hydrostatic test requirements for non-bulk UN standard packagings. In this final rule, we are relocating the last sentence in paragraph (d)(3) requiring the performance of a pressure test on packagings intended to contain Packing Group I hazardous materials at a minimum test pressure of 250 kPa (36 psig) to paragraph (d) introductory text, preceding the list of methods contained in paragraphs (d)(1)-(d)(3). We are making this revision to clarify that this pressure test requirement applies regardless of the method chosen to determine the pressure.

Part 179

Section 179.400-18

This section prescribes pressure test requirements for the inner tanks of DOT-113 and DOT-107A cryogenic liquid tank car tanks and seamless steel tanks. Paragraph (a) is revised to specify the metric conversion of 100 °F as 38 °C for consistency throughout the HMR.

Part 180

Section 180.209

This section prescribes requirements for the periodic requalification of DOT specification cylinders. We are revising paragraph (l) introductory text to change “§ 171.12a” to correctly reference §§ 171.12(a) and 171.23(a), and paragraph (l)(2) to correctly reference certain export requirements contained in § 171.23(a)(4).

III. Regulatory Analyses and Notices

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. This rule is not significant under the Regulatory Policies and Procedures of the Department of Transportation (44 FR 11034). This final rule does not impose new or revised requirements for hazardous materials shippers or carriers; therefore, it is not necessary to prepare a regulatory impact analysis.

Executive Order 13132

This final rule has been analyzed in accordance with the principles and criteria in Executive Order 13132 (“Federalism”). This final rule does not adopt any regulation that: (1) 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; or (2) imposes substantial direct compliance costs on state and local governments. PHMSA is not aware of any state, local, or Indian tribe requirements that would be preempted by correcting editorial errors and making minor regulatory changes. This final rule does not have sufficient federalism impacts to warrant the preparation of a federalism assessment.

Executive Order 13175

This final rule has been analyzed in accordance with the principles and criteria contained in Executive Order 13175 (“Consultation and Coordination with Indian Tribal Governments”). Because this final rule does not have tribal implications, does not impose substantial direct compliance costs on Indian tribal governments, and does not preempt tribal law, the funding and consultation requirements of Executive Order 13175 do not apply, and a tribal summary impact statement is not required.

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

I certify that this final rule will not have a significant economic impact on a substantial number of small entities. This rule makes minor editorial changes which will not impose any new requirements on persons subject to the HMR; thus, there are no direct or indirect adverse economic impacts for small units of government, businesses, or other organizations.

Unfunded Mandates Reform Act of 1995

This rule does not impose unfunded mandates under the Unfunded Mandates Reform Act of 1995. It does not result in costs of $120.7 million or more to either state, local, or tribal governments, in the aggregate, or to the private sector, and is the least burdensome alternative that achieves the objectives of the rule.

Paperwork Reduction Act

There are no new information collection requirements in this final rule.

Environmental Impact Analysis

There are no environmental impacts associated with this final rule.

Regulation Identifier Number (RIN)

A regulation identifier number (RIN) is assigned to each regulatory action listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN number contained in the heading of this document can be used to cross-reference this action with the Unified Agenda.

§ 178.275

Specification for UN portable tanks intended for the transportation of liquid and solid hazardous materials.

* * * * *

(d) * * *

(3) Except as provided in paragraph (d)(2) of this section, every bottom discharge outlet must be equipped with three serially fitted and mutually independent shut-off devices. The design of the equipment must include: * * *

* * * * *

(i) * * *

(2) The combined delivery capacity of the pressure relief system (taking into account the reduction of the flow when the portable tank is fitted with frangible-discs preceding spring-loaded pressure-relief devices or when the spring-loaded pressure-relief devices are provided with a device to prevent the passage of the flame), in condition of complete fire engulfment of the portable tank must be sufficient to limit the pressure in the shell to 20% above the start to discharge pressure limiting device (pressure relief device). The total required capacity of the relief devices may be determined using the formula in paragraph (i)(2)(i)(A) of this section or the table in paragraph (i)(2)(iii) of this section.

(i)(A) To determine the total required capacity of the relief devices, which must be regarded as being the sum of the individual capacities of all the contributing devices, the following formula must be used:

Where:

Q = minimum required rate of discharge in cubic meters of air per second (^m3/_s) at conditions: 1 bar and 0 °C (273 °K);

F = for uninsulated shells: 1; for insulated shells: U(649−t)/13.6 but in no case is less than 0.25

Where:

U = thermal conductance of the insulation, in kW m⁻²K⁻¹, at 38 °C (100 °F); and t = actual temperature of the hazardous material during filling (in °C) or when this temperature is unknown, let t = 15 °C (59 °F). The value of F given in this paragraph (i)(2)(i)(A) for insulated shells may only be used if the insulation is in conformance with paragraph (i)(2)(iv) of this section;

A = total external surface area of shell in square meters;

Z = the gas compressibility factor in the accumulating condition (when this factor is unknown, let Z equal 1.0);

T = absolute temperature in Kelvin (°C + 273) above the pressure relief devices in the accumulating condition;

L = the latent heat of vaporization of the liquid, in kJ/kg, in the accumulating condition;

M = molecular weight of the hazardous material.

(B) The constant C, as shown in the formula in paragraph (i)(2)(i)(A) of this section, is derived from one of the following formulas as a function of the ratio k of specific heats:

Where:

c_p is the specific heat at constant pressure; and

c_v is the specific heat at constant volume.

(C) When k >1:

(D) When k = 1 or k is unknown, a value of 0.607 may be used for the constant C. C may also be taken from the following table:

(ii) As an alternative to the formula in paragraph (i)(2)(i)(A) of this section, relief devices for shells used for transporting liquids may be sized in accordance with the table in paragraph (i)(2)(iii) of this section. The table in paragraph (i)(2)(iii) of this section assumes an insulation value of F = 1 and must be adjusted accordingly when the shell is insulated. Other values used in determining the table in paragraph (i)(2)(iii) of this section are: L = 334.94 kJ/kg; M = 86.7; T = 394 °K; Z = 1; and C = 0.607.
