00-21417. Harmonization With the United Nations Recommendations, International Maritime Dangerous Goods Code, and International Civil Aviation Organization's Technical Instructions

AGENCY:

Research and Special Programs Administration (RSPA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

RSPA proposes to amend the Hazardous Materials Regulations (HMR) to maintain alignment with international standards by incorporating various changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations and vessel stowage requirements. In addition, RSPA proposes to revise the requirements for intermediate bulk containers and UN portable tanks for alignment with international requirements. Because of recent changes to the International Maritime Dangerous Goods Code (IMDG Code), the International Civil Aviation Organization's Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions), and the United Nations Recommendations on the Transport of Dangerous Goods (UN Recommendations), these proposed revisions are necessary to facilitate the transport of hazardous materials in international commerce.

SUPPLEMENTARY INFORMATION:

I. Background

On December 21, 1990, the Research and Special Programs Administration (RSPA) (hereafter, “we” and “our” means “RSPA”) published a final rule based on the UN Recommendations [Docket HM-181; 55 FR 52402] which comprehensively revised the Hazardous Materials Regulations (HMR), 49 CFR parts 171 to 180, with respect to hazard communication, classification, and packaging requirements. The intended effect of the rule was to facilitate the international transportation of hazardous materials by ensuring a basic consistency between the HMR and international regulations, while at the same time ensuring the safe transportation of hazardous materials.

The UN Recommendations are not regulations, but are recommendations issued by the UN Committee of Experts on the Transport of Dangerous Goods. These recommendations are amended and updated biennially by the UN Committee of Experts. They serve as the basis for national, regional, and international modal regulations (specifically, the IMDG Code, issued by the International Maritime Organization (IMO), and the ICAO Technical Instructions, issued by the ICAO Dangerous Goods Panel). In 49 CFR 171.12, the HMR authorize hazardous materials shipments prepared in accordance with the IMDG Code if all or part of the transportation is by vessel, subject to certain conditions and limitations. Offering, accepting and transporting hazardous materials by aircraft, in conformance with the ICAO Technical Instructions, and by motor vehicle either before or after being transported by aircraft, are authorized in § 171.11, subject to certain conditions and limitations.

Since publication of the 1990 final rule, we have issued three additional international harmonization final rules, (Dockets HM-215A, 59 FR 67390; HM-215B, 62 FR 24690; and HM-215C, 64 FR 10742). The rules provided additional harmonization with international air and sea transportation requirements by more fully aligning the HMR with the corresponding biennial updates of the UN Recommendations, the IMDG Code and the ICAO Technical Instructions.

The continually increasing amount of hazardous materials transported in international commerce warrants the harmonization of domestic and international requirements to the greatest extent possible. Harmonization serves to facilitate international transportation and at the same time ensures the safety of people, property and the environment. Therefore, in our efforts to continue the alignment of the HMR with international requirements, this NPRM proposes changes to the HMR based on the eleventh revised edition of the UN Recommendations, the 2001-2002 ICAO Technical Instructions and Amendment 30 to the IMDG Code, all of which become effective January 1, 2001. Petitions for rulemaking pertinent to harmonization with international standards and the facilitation of international transportation are also addressed in this NPRM and serve as the basis of certain proposed changes. Other proposed changes are based on feedback from the regulated industry, RSPA and other DOT modal administrations, including a few proposed editorial clarifications and a Class 1 (explosives) placarding allowance for certain compatibility groups. Unless otherwise stated, the revisions are proposed for harmonization with international standards.

II. Overview of Proposed Changes in this NPRM

Proposed amendments to the HMR in this NPRM include:

—Incorporation by reference of the updated ICAO Technical Instructions, IMDG Code and UN Recommendations and addition of incorporation by reference of six current standards which include an International Atomic Energy Agency (IAEA) safety standard, an IMO safety standard, three International Organization for Standardization (ISO) standards and one American Society for Testing Materials (ASTM) standard.

—Amendments to the Hazardous Materials Table (HMT) which would add, revise or remove certain proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, bulk packaging requirements, and passenger and cargo aircraft maximum quantity limitations. Proper shipping name amendments include the proposal to replace the word “inhibited” with “stabilized.” Entry removals include certain domestic entries for which corresponding UN entries are included in the HMT.

—Revision of vessel stowage category definitions and codes for Class 1 (explosive) materials.

—Revision of shipping paper requirements for sea transport.

—Addition, removal and revision of certain entries to the List of Marine Pollutants.

—Addition, removal and revision of special provisions, including removal of current T codes and IBC bulk provisions and addition of UN portable tank codes and IBC special packing provisions, consistent with those in the UN Recommendations.

—Removal of the requirement to distinguish between primary and subsidiary risk labels and placards.

—Addition and revision to the list of organic peroxides and the list of self-reactive substances.

—Revision of the requirements pertaining to the transportation of samples.

—Revision of intermediate bulk container (IBC) requirements including amendments to the IBC commodity sections in §§ 173.240, 173.241, 173.242, 173.243 and 173.247, and addition of UN IBC packing instructions and special IBC packing provisions in part 172.

—Incorporation of the design, construction and use requirements for UN portable tanks.

—Consolidation of current portable tank maintenance, approval and use requirements.

—Inclusion of flexible grandfather provisions for the continued use of IM 101, IM102 and DOT 51 portable tanks.

—Removal of specifications for DOT 52 and 53 portable tanks and the provisions for their continued use.

—Incorporation of a provision for the use of the “W” mark for IBCs.

—Inclusion of a 12 mm minimum marking size for IBCs.

—Revision of minimum thickness requirements for metal IBCs.

—Revision of several explosives packing methods to allow a broader selection of authorized packagings.

—Revision of provisions for cigarette lighters and alcoholic beverages carried aboard aircraft.

—Allowance of the display of one placard when certain explosive compatibility groups are transported together.

—Revision of lithium battery requirements.

III. Summary of Regulatory Changes by Section

Part 171

Section 171.7. We propose to update the incorporation by reference for the ICAO Technical Instructions, the IMDG Code, the UN Recommendations and the UN Manual of Tests and Criteria. In addition, we propose to add an ASTM standard, the current edition of the IAEA safety standard, an IMO standard, and three ISO standards.

All of the updated incorporation by reference material will become effective January 1, 2001 and would be updated as follows:

—The ICAO Technical Instructions—2001-2002 edition.

—The IMDG Code—Amendment 30.

—The UN Recommendations—eleventh revised edition.

—The UN Manual of Tests and Criteria—third revised edition.

Additionally, all of the proposed added incorporation by reference material would become effective January 1, 2001 and would be added as follows:

—ASTM's “E 112-96 Standard for Test Methods for Determining Average Grain Size” would be added to define “fine grain steel” as included in the proposed incorporation of the UN portable tank specifications in § 178.274.

—IAEA's current “Regulations for the Safe Transport of Radioactive Material, No. ST-1,” 1996 edition would be added while retaining the previous edition entitled, “Regulations for the Safe Transport of Radioactive Material, Safety Series No. 6.” The ST-1 requirements were incorporated in the IMDG Code and the ICAO Technical Instructions which will both be effective January 1, 2001. Adding the updated ST-1 edition and retaining Safety Series No. 6 would afford the flexibility necessary in an interim period when international shipments are required to be in accordance with the ST-1 edition. Domestic shipments would remain subject to the HMR requirements, which are based on Safety Series No. 6 pending amendment of these requirements under a separate rulemaking.

—IMO'S current “International Code for the Safe Carriage of Packaged Irradiated Nuclear Fuel, Plutonium and High-Level Radioactive Wastes on Board Ships' (INF Code) would be added. The IMO Maritime Safety Committee adopted the INF Code for incorporation into the IMDG Code. In addition, the INF Code is being made mandatory for international transportation effective January 1, 2001, through an amendment to Chapter VII of the International Convention for the Safety of Life at Sea, 1974 (SOLAS 1974, as amended). The incorporation by reference and inclusion of the proposed new § 176.720 requirement for a vessel carrying irradiated nuclear fuel, plutonium and high-level radioactive wastes would align the HMR with these international standards. (Also, see § 176.2. and § 176.720.)

—Finally, we are proposing to add three ISO standards to coincide with the proposed incorporation of the UN portable tank requirements. The standards are as follows: “ISO 1496-3 Series 1 freight containers—Specification and testing,” 1996 edition; “ISO 4126-1 Safety valves-Part 1: General Requirements,” 1991 edition; and, “ISO 6892 Metallic materials—Tensile testing,” 1984 edition.

Section 171.8. We would add four new definitions to § 171.8. “Large packaging” would be added to correspond with the proposed addition of an approval provision that would allow the use of large packagings which comply with requirements in the UN Recommendations (see § 178.801). Large packagings are UN-marked bulk packagings which are very similar to IBCs, with the exception that they contain inner packagings. “Liner” would be added for clarification purposes. “Stabilized” would be added in conjunction with the proposal to replace the word “inhibited” with “stabilized” in proper shipping names (see § 172.101). Finally, “UN portable tank” would be added in conjunction with the proposal to include requirements for the design, construction and use of UN portable tanks (see §§ 178.274, 178.275, 178.276, 178.277).

Section 171.10. To correspond with the proposed incorporation of the UN portable tank specifications, we would add the unit of measure for “Newton” into the Table of Conversion Factors in paragraph (c)(2).

Section 171.11. We propose to add a new paragraph (d)(17) to ensure conformance with the current approval provision in § 173.128(d) which requires an approval from the Associate Administrator for the offering for transportation or transport of organic peroxides that are not identified by technical name in the § 173.225(b) Organic Peroxide Table. (We also propose to add the new paragraph under §§ 171.12 and 171.12a.)

Section 171.12. Paragraph (b)(3) would be revised by adding a limitation to the use of the IMDG Code by requiring that viscous flammable liquids, which are excepted from the IMDG Code when in a packaging of less than 450 liters (118.9 gallons) capacity, are subject to the HMR. We do not agree that the IMDG Code exception provides an adequate level of safety and opposed its incorporation in the ICAO Technical Instructions, the IMDG Code and UN Recommendations. We believe this requirement is necessary to ensure that importers and exporters are aware that these viscous flammable liquids are regulated in the United States. We also propose to add a new paragraph (b)(19) to ensure conformance with the current approval provision in § 173.128(d), which requires an approval from the Associate Administrator for the offering for transportation or transport of organic peroxides that are not identified by technical name in the § 173.225(b) Organic Peroxide Table. Finally, we proposed to revise paragraph (d) to reflect the addition of the current edition of the IAEA “Regulations for the Safe Transport of Radioactive Material, No. ST-1,” 1996 edition. (See § 171.7 for discussion concerning the addition of the updated ST-1 standards.)

Section 171.12a. We propose to add a new paragraph (b)(18) to ensure conformance with the current approval provision in § 173.128(d) which requires an approval from the Associate Administrator for the offering for transportation or transport of organic peroxides that are not identified by technical name in the § 173.225(b) Organic Peroxide Table.

Section 171.14. We propose to revise paragraphs (d) and (d)(1) to authorize a delayed implementation date for the amendments adopted in the HM-215D final rule. The effective date of this final rule would be October 1, 2001. However, we would authorize a voluntary compliance date of January 1, 2001. This authorization would allow shippers to prepare their international shipments in accordance with the new ICAO Technical Instructions, the IMDG Code and the HMR provisions. We also would authorize a delayed mandatory compliance date comparable to the transition provisions provided in the final rule under Docket HM-215C. The delayed mandatory compliance date would offer sufficient time to implement the new provisions and deplete current stocks of shipping papers, labels, placards and packagings affected by the new requirements.

We would revise paragraph (d)(2) to permit intermixing old and new (HM-215D) hazard communication requirements until October 1, 2002.

We would add a new paragraph (d)(4) to allow the use of the T code special provisions (proposed to be assigned to a hazardous material in Column (7) of the HMT) in effect on December 31, 2000 until January 1, 2010 for hazardous materials offered for transportation in IM and IMO portable tanks. This proposal is consistent the IMDG Code and would minimize any undue regulatory burden.

Part 172

Section 172.101. For alignment with international standards, we would revise paragraph (c)(11) and add new paragraphs (k)(6) through (k)(20). Consistent with the eleventh revised edition of the UN Recommendations, we would revise paragraph (c)(11) for materials transported as samples which are assigned a tentative proper shipping name, hazard class, identification number and packing group. We would revise the requirements by requiring the word “SAMPLE” to be included in association with the proper shipping name and by prohibiting the samples from being packaged together with other hazardous materials. We also would add a new paragraph (c)(16) to allow for the inclusion of the qualifying words “liquid,” “solid” or “molten,” as applicable, to a proper shipping name.

Consistent with the new stowage categories and terminology contained in Amendment 30 of the IMDG Code, we would add new paragraphs (k)(6) through (k)(20) to include the IMDG vessel stowage category definitions for Class 1 (explosive) materials. (Also see preamble discussion under “The Hazardous Materials Table” and § 176.63.)

The Hazardous Materials Table (HMT). Proposed amendments to the HMT for the purpose of harmonizing with the eleventh revised edition of the UN Recommendations (unless otherwise stated) would include the following:

—For the entries, “Other regulated substances, liquid, n.o.s.” and “Other regulated substances, solid, n.o.s.,” we would add the letter “G” to Column (1). The letter “G,” which denotes the n.o.s. and generic proper shipping names which are required to be supplemented with the technical names of the hazardous material (in parentheses and in association with the basic description), was inadvertently omitted in Docket HM-215C (64 FR 10742).

—We would add the following new entries: “Nitroglycerin mixture, desensitized, liquid, n.o.s. with not more than 30% nitroglycerin by mass,” UN3357; “Propellant, solid,” UN0501; “Refrigerating machines containing flammable, non-toxic, liquefied gas,” UN3358; “Rockets with inert head,” UN0502; and “1H-Tetrazole,” UN0504.

—We would revise the entry, “Dangerous Goods in Machinery or Dangerous Goods in Apparatus” by replacing the identification number NA8001 with UN3363, designating a Class 9 assignment and revising Special Provision 136 (see § 172.102). These proposed changes reflect the adoption of the entry by the UN Committee of Experts and amendments agreed to by the ICAO Dangerous Goods Panel. The entry was added to the HMT under Docket HM-215C as NA8001 and assigned Special Provision 136 to prescribe the appropriate hazard class assignment. As explained in HM-215C, the entry was adopted in the ICAO Technical Instructions to provide an exception from the UN packaging performance tests for equipment, machinery or apparatus containing small quantities of hazardous materials. For machinery or apparatus not specifically listed in the HMT, the entry provides a practical means of describing and transporting machinery or apparatus containing small quantities of hazardous materials. In HM-215C, we stated that upon the assignment of a UN identification number, we would revise the entry accordingly. This was accomplished in the eleventh revised edition of the UN Recommendations in which UN3363 was assigned and this entry was assigned to Class 9. The ICAO Technical Instructions were amended consistent with this UN decision. Therefore, based on the above discussion, we are proposing to revise the entry, “Dangerous Goods in Machinery or Dangerous Goods in Apparatus” by assigning it to Class 9, replacing the domestic identification number with an international identification number, and revising Special Provision 136.

—We are proposing to revise all proper shipping names containing the word “inhibited” by replacing “inhibited” with the word “stabilized.” (Also, see proposed definition for “stabilized” in § 171.8.) Replacing the word “inhibited” with “stabilized” would recognize that, in addition to inhibition, other means of controlling self-reaction would be acceptable. The proposed allowance of additional means of stabilization and the proposed removal of certain domestic entries from the HMT (see domestic entry removals later in this section) would also address a petition for rulemaking (P-1304) requesting that we add a new domestic entry, “Methyl methacrylate monomer, uninhibited,” Class 3, NA1247, PG II to the HMT.

—We would revise the following proper shipping names: “Lithium hypochlorite, dry or Lithium hypochlorite mixtures, dry,” UN1471; “Printing ink, flammable,” UN1210; and “Nitrocellulose membrane filters,” UN3270.

—For the entry, “Methacrylic acid, inhibited,” UN2531, we would replace Packing Group III with Packing Group II.

—We propose to remove various domestic entries that have assigned “NA” identification numbers. After reviewing the domestic entries, we determined that the HMR includes “UN” identification numbers assigned to entries that are equally appropriate in a number of instances, and in these instances the NA numbers are no longer necessary. Included in the proposed removals are seven domestic pesticide proper shipping names identified by the pesticide industry as no longer being used. These entries are: “Aldrin, liquid,” NA2762; “Aldrin, solid,” NA2761; “Dieldrin,” NA2761; “Methyl parathion liquid,” NA3018; “Methyl parathion solid, NA2783; “Parathion,” NA2783 and “Tetraethyl pyrophosphate solid,” NA3018.

—We would add radioactive material (Class 7) entries consistent with new entries introduced in the UN Recommendations and IAEA's “Regulations for the Safe Transport of Radioactive Material, No. ST-1” and revise the current radioactive material entries in the HMR to allow for domestic shipment only.

—For Class 1 (explosive) entries, we would revise Columns (10A) and (10B) to reflect the vessel stowage codes as they are presented in Amendment 30 to the IMDG Code. (See § 172.101(k) and § 176.63.)

—For the international entry “Methanol,” we would add a plus mark (+) in Column (1) of the HMT to indicate that this entry is classified with a subsidiary hazard of Class 6.1 on the basis of human experience.

—We would remove the entry “Isobutyric anhydride,” UN2530.

—For the entry “Morpholine,” UN2054, we would replace Class 3 with Class 8, replace Packing Group III with Packing Group I , and add Class 3 as the subsidiary hazard.

—For “Organic peroxide type F, solid, temperature controlled,” (UN3120), we would remove the Packing Group III entry that was due to a printing error in 49 CFR. The PG II entry would remain.

—For approximately 14 Zone A and B toxic-by-inhalation entries, we would revise the quantity limits for transport by air to “forbidden.” These revisions would be consistent with other toxic-by-inhalation entries in the HMT.

—For the entry “Fire extinguishers containing compressed or liquefied gas” we would add Special Provision 110 to Column (7).

—Based on a petition for rulemaking (P-1338) that we received from the Aluminum Company of America (Alcoa), we propose to add Special Provisions 128 and B115 to the entry, “Magnesium granules, coated, particle size not less than 149 microns,” UN2950. Special Provision 128 allows material meeting the Class 8 definition to be classed as a Division 4.3 with a Class 8 subsidiary hazard. Special Provision B115 authorizes the use of certain non-specification bulk packagings when the material being transported is loaded dry. Special Provisions 128 and B115 are currently assigned to “Aluminum smelting by-products or Aluminum remelting by-products.” Alcoa states that magnesium granules exhibit the same hazard properties as aluminum smelting and remelting by-products and behave similarly to these materials by occasionally meeting the criteria for both Division 4.3 and Class 8 materials. We agree with the petitioner and propose to add Special Provisions 128 and B115 to the entry “Magnesium granules, coated, particle size not less than 149 microns,” UN2950. (Also, see § 172.102, Special Provision 128.)

—For approximately 1,600 entries, we would revise Column (7) by harmonizing the HMR authorizations for IBCs with those contained in the UN Recommendations. In most cases, the UN Recommendations provide for greater flexibility in the use of different types of IBCs. However, in a few instances, the incorporation of the UN IBC requirements would further restrict the types of IBCs that are currently authorized for certain hazardous materials. For example, some Packing Group II liquid hazardous materials of Class 3, Division 6.1 and Class 8 that are currently authorized to be transported in composite IBCs with flexible inner receptacles (such as 31HZ2) would not be authorized in these types of IBCs if the UN provisions are adopted. For the benefit of the reader and to facilitate a review of the proposed amendments, we have included a table identifying all of the affected hazardous materials and indicating the current bulk assignments and the proposed IBC assignments. We would set out the IBC packaging requirements in a newly-created IBC Table under the Special Provisions section in § 172.102(c)(4). The table would consist of IBC Codes (using the designations 1B1-1B99) corresponding to the UN IBC packing instructions, and BB Codes corresponding to the UN IBC special packing provisions. We would assign the IBC packing instructions and the BB codes to specific hazardous materials in Column (7) of the § 172.101 HMT consistent with assignments in the UN Recommendations. In addition, we believe that consolidating the IBC requirements into one table would make it easier for readers to identify the authorized IBCs for specific hazardous materials and would enhance safety and international harmonization. As a result of this proposal, we would revise the bulk special provisions in § 172.102 (c)(3) to remove the current bulk codes relevant to the use of IBCs. We would also revise the current IBC packaging authorizations under §§ 173.240(d), 173.241(d), 173.242(d) and 173.243(d).

This proposal also addresses a petition we received from the Rigid Intermediate Bulk Container Association (RIBCA) (P-1395) requesting that we amend the HMR to expand the use of IBCs consistent with new UN provisions. Specifically, the petitioner requested uniformity with the UN Recommendations by requesting that the HMR allow the use of rigid plastic IBCs and composite IBCs with a rigid plastic inner receptacle for certain liquids. We are in agreement with RIBCA's request; however, in the interest of harmonization, we believe it would be more beneficial to adopt the UN Recommendations' IBC packing instructions in totality, and, as such, present the proposal as discussed above.

For purposes of the Government Printing Office's typesetting procedures, readers should be aware that for certain entries in the HMT, such as those with revised proper shipping names, the change may appear as a removal and addition, as opposed to a revision of the regulatory text in the Column (2) changes. Readers should review all changes appearing in the § 172.101 regulatory text for a complete view of the proposed changes.

Appendix B to § 172.101. For the readers' convenience, in Appendix B to § 172.101, List of Marine Pollutants, we would revise paragraph “1” by referencing § 171.4, which contains the applicability and exceptions for offering for transportation or transporting marine pollutants. We would revise paragraph “2” to reflect the IMDG Code's provision for the use of two Class 9 proper shipping names when a marine pollutant is not listed by name or by synonym in the HMT and does not meet the definitions of Class 1 through 8. In addition, a number of materials would be added, removed or amended in the List of Marine Pollutants. Included is the proposed removal of the entry “EPTC (ISO)” which also was the subject of a petition for rulemaking (P-1360) requesting removal of the entry based on its removal from the IMDG Code. Various other entries previously identified as marine pollutants are proposed to be removed. All of the proposed amendments to the List of Marine Pollutants are consistent with the marine pollutants provided in Amendment 30 of the IMDG Code.

Section 172.102. We propose to revise, add and remove special provisions as follows:

—Special Provision 43 would be revised to include a provision which would except “Nitrocellulose membrane filters,” UN3270 from the HMR requirements if shown not to meet the criteria for a Division 4.1 hazardous material, according to burn rate tests in Sub-section 33.2.1. of the UN Manual of Tests and Criteria, Part III.

—Special Provision 110 would be revised to more fully identify fire extinguishers that may be assigned to certain proper shipping names. The proposal would also provide for harmonization with the ICAO Technical Instructions. (We also propose to add the special provision to the entry, “Fire extinguishers containing compressed or liquefied gas.” See § 172.101 proposed HMT changes.)

—Special Provision 128 would be revised based on the proposal to assign it to “Magnesium granules, coated, particle size not less than 149 microns.” (See § 172.101, proposed Column (7) changes.)

—Special Provision 136 would be revised to reflect the changes adopted by the UN Committee of Experts and the ICAO Dangerous Goods Panel for the entry “Dangerous Goods in Machinery or Dangerous Goods in Apparatus.” (Also see § 172.101.) We would revise the special provision by removing the text specific to the determination of the hazard class based on the UN Committee of Experts' decision that items under this entry should be assigned to Class 9.

—A new Special Provision 139 would be added for two new proposed entries, “Radioactive material, transported under special arrangement, fissile” and “Radioactive material, transported under special arrangement non-fissile or fissile-excepted.” The special provision requires international shipments using the two entries to be made under an IAEA Certificate of Competent Authority to be issued by the U.S. Competent Authority. Domestic shipments transported under the two entries would be allowed only under a DOT exemption.

—A new Special Provision 142 would be assigned for the new entry “Nitroglycerin mixture, desensitized, liquid, n.o.s.” The special provision would require the material to be approved by the Associate Administrator.

—A new Special Provision 143 would be added for the entry “Life-saving appliances, not self-inflating, containing dangerous goods as equipment.” The special provision would clarify which articles may be transported under this entry.

— In conjunction with the proposal to revise and consolidate the IBC requirements (see § 172.101, Column (7) changes), we would make the following changes: revise the special provisions for bulk packagings in paragraph (c)(3) to exclude IBCs by revising Special Provisions B53 and B69 and removing Special Provisions B100, B101, B103 through B106 and B108 through B110, and a new paragraph (c)(4) would be added for special provisions specific to IBCs (BB Codes).

—The current T codes in paragraph (c)(7) would be revised to reflect the proposed incorporation of requirements for UN portable tanks and would apply to hazardous materials of Classes 2 through 9. The revised T codes would be consistent with those in the UN Recommendations and the IMDG Code and would supersede the current HMR IM portable tank T codes. The T code provisions would be required in addition to the proposed requirements in part 178. The codes specify the types of authorized portable tanks according to the specific hazardous material transported in the portable tank. Portable tank assignments for Zone A and Zone B toxic-by-inhalation liquids would remain consistent with their current assignments in the HMR. In instances where the UN requires a competent authority approval for transportation in portable tanks (such as when TP9 is assigned in the UN Recommendations), we have removed the approval provision. A transition period would be provided for the continued use of the existing T codes for IM portable tanks (see § 171.14(d)(5)).

—A new Special Provision W7 would be added for seven proposed new Class 7 entries and would assign the vessel stowage category “D,” as defined in § 172.101(k)(4), to uranyl nitrate hexahydrate solution.

—A new Special Provision W8 would be added for four proposed new Class 7 entries and would assign the vessel stowage category “D,” as defined in § 172.101(k)(4), to pyrophoric thorium metal or pyrophoric uranium metal.

—Finally, a new Special Provision W9 would be added for assignment to the entries, “Calcium hypochlorite, dry or Calcium hypochlorite mixtures dry with more than 39 percent available chlorine (8.8 percent available oxygen,” UN1748; “Calcium hypochlorite, hydrated or Calcium hypochlorite, hydrated mixtures with not less than 5.5 percent but not more than 10 percent water,” UN2880; and “Calcium hypochlorite mixtures, dry, with more than 10 percent but not more than 39 percent available chlorine.” UN2208. This proposed action would align the packaging requirements for these entries with those contained in Amendment 30 to the IMDG Code by authorizing certain packagings only when approved by the Associate Administrator.

Section 172.203. We are proposing to revise paragraphs (d)(11), (i) and (n). In paragraph (d)(11), we propose to allow an exception from the requirement to add the appropriate group notation to the shipping description for a shipment of low specific activity material or surface contaminated objects provided the symbols are contained in the proper shipping name.

In paragraph (i), we would add two additional shipping paper description requirements for transportation by vessel. The first amendment would be added as new paragraph (i)(5) and would require the flashpoint for a liquid hazardous material with a flashpoint of 61 °C or below to be included on shipping papers when transported by water. We received a petition (P-1402) from the Vessel Operators Hazardous Materials Association (VOHMA) requesting that we add an additional shipping paper description requirement to include the minimum flashpoint in degrees Celsius for Class 3 (flammable) or combustible liquid hazardous materials. VOHMA stated that the amendment would help support compliance with the current stowage requirements in § 176.305(c) and the segregation requirements (Code 22 and 23, see § 176.84) as designated in Column (10B) of the § 172.101 Hazardous Materials Table. We agree with the petitioner's reasoning; however, for consistency with the IMDG Code, we propose to add the requirement to specify the flashpoint when it is 61 °C or below for all such liquid hazardous materials whether or not the primary hazard is Class 3. The second amendment to the additional shipping paper description requirements for transportation by vessel would be added as new paragraph (i)(6) and is based on comments from the USCG regarding further harmonization with the IMDG Code. The amendment would require subsidiary risks of a hazardous material that are not reflected in the proper shipping name to be included on shipping papers.

Finally, in paragraph (n), we are proposing to clarify that the shipping paper requirement for the word “HOT” to be placed immediately preceding the proper shipping names of hazardous materials that are transported as elevated temperature materials, is not required for proper shipping names containing the words “Molten” or “Elevated temperature.”

Sections 172.402, 172.405 and 172.411. Consistent with the eleventh revised edition of the UN Recommendations, we are removing the requirement to differentiate between primary and subsidiary labels. Currently, primary labels are required to display the hazard class or division number in the lower corner of the label, while subsidiary labels may not display these numbers. We are proposing to amend the requirement which provides for two label specifications (one for primary hazards and one for subsidiary hazards) by removing the subsidiary hazard label specification. Upon adoption of this proposal, labels used to convey both primary and subsidiary hazards would display the appropriate hazard class or division number at the bottom of the label. This proposed change would provide relief by eliminating the need for shippers to stock two sets of labels. We also propose to allow labels meeting the current label specifications to continue to be displayed until October 1, 2005.

Section 172.504. Based on comments and our own initiative, we are proposing to allow the display of only one placard displaying one compatibility letter when certain Class 1 materials (explosives) of different compatibility groups are transported together in a single transport vehicle or container. This proposal is consistent with the mixed packaging allowances in § 173.61.

Section 172.519. Consistent with the proposal to eliminate the distinction between primary and subsidiary labels, we would revise paragraph (b)(4) to eliminate the requirement for placards. In addition, we would incorporate a new paragraph (b)(4)(i) to permit subsidiary placards meeting the current placarding specifications (such as placards without the hazard class or division number displayed in the lower corner of the placard) to continue to be displayed provided they were permanently affixed before January 1, 2001. Non-permanently affixed subsidiary placards meeting the current placarding specifications would be allowed to be displayed until October 1, 2005 or until current stocks are depleted, whichever occurs first.

Part 173

Section 173.2a. Consistent with the eleventh revised edition of the UN Recommendations, we would revise Note 2 to exclude liquid and solid desensitized explosives. In addition, we would add the revised Note 2 to Class 3, PG I, II and III.

Section 173.4. Based on a request for clarification, we would revise paragraph (a) to clarify that the small quantity exceptions apply to packagings containing articles, as well as inner receptacles.

Section 173.24b. We would add a new paragraph (e) to address acceptance of foreign manufactured UN portable tanks that conform to the applicable provisions in the UN Recommendations on the Transport of Dangerous Goods and are manufactured in countries that provide reciprocal treatment for UN portable tanks manufactured in the United States.

Section 173.28. We would correct a reference in paragraph (d)(1)(ii). The paragraph currently references “§ 173.225(c)(5)” and would be corrected to read § 173.225(c)(3).”

Section 173.32. We are proposing to revise this section to provide requirements for all portable tanks by consolidating the requirements for the use of IM portable tanks currently in § 173.32(c) into a single section. We are proposing to consolidate the qualification and maintenance requirements in § 173.32(c) and move them to part 180, subpart G, with the qualification and maintenance requirements for IBCs, cargo tanks and tank cars. We are also proposing to include a grandfather clause in this section (§ 173.32) to allow IM 101, 102 and DOT 51 portable tanks to continue to be constructed in accordance with the HMR until January 1, 2003. IM 101, 102 and DOT 51 portable tanks which are certified and approved prior to this date would be authorized for continued use provided they meet the applicable periodic inspection and test requirements proposed in part 180, subpart G. These requirements are currently in § 173.32b. On January 1, 2003, all newly manufactured portable tanks would be required to conform to the requirements for the design, construction and approval of UN portable tanks (see §§ 178.274, 178.275, 178.276 and 178.277). In addition, we are proposing to remove the provisions for the continued use of DOT Specification 52 and 53 portable tanks and ICC Specification portable tanks based on information we received that these portable tanks are no longer used. We specifically request comments with regard to removing these provisions.

Section 173.32a. We are proposing to remove § 173.32a and move its approval requirements for Specification portable tanks to proposed § 178.273. We believe that part 178 is a more appropriate location for these requirements and that the new section will prove to be more convenient for users of the HMR. We also propose to include similar requirements for the proposed incorporation of requirements for UN portable tanks.

Section 173.32b. We are proposing to remove § 173.32b and relocate the test requirements to part 180, subpart G, as discussed in § 173.32.

Section 173.32c. We are proposing to remove § 173.32c. The requirements for the use of all Specification portable tanks would be included in § 173.32, thereby precluding the need for this section.

Section 173.61. Based on our own initiative, for Class 1 (explosives) mixed packaging requirements, we would revise paragraph (e)(3) to allow explosives of compatibility group S that are allowed to be packaged with explosives of all other compatibility groups, except A and L, to be treated as belonging to any of the packaged compatibility groups except S. In addition, we would add a new paragraph (e)(8) to allow explosive articles of compatibility groups C, D, E and G, except for fireworks and articles requiring special packaging, to be treated as belonging to compatibility group E. This proposed revision corresponds with the current allowance contained in § 177.848(g).

Section 173.62. In paragraph (c), we would revise the Explosives Packing Instructions Table to authorize additional types of outer packagings in the following packing instructions: 112(a), 112(b), 112(c), 113, 115, 116, 130, 131, 134, 135, 136, 138, 140, 141,142 and 144.

Section 173.150. We would revise paragraph (d) by clarifying that alcoholic beverages containing over 24% alcohol by volume are not excepted from regulation when transported by a passenger or crewmember on passenger-carrying aircraft. (See preamble discussion under § 175.10.)

Section 173.162. We would revise paragraph (a)(1) by clarifying that the types of packagings specified in the paragraph are combination packagings and that the glass, earthenware or rigid plastics are inner packagings. In addition, for these packagings, we would increase the net mass of 10 kg (22 pounds) for each packaging to15 kg (33 pounds). This is consistent with Packing Instruction 800 in the UN Recommendations.

Section 173.185. We would revise § 173.185 to include a definition for equivalent lithium content for lithium ion cells and batteries and to provide the applicable aggregate lithium quantities relevant to excepting lithium ion cells and batteries from the requirements of the HMR.

Section 173.224. Consistent with the UN Recommendations, we would add the entry “2,2'-Azodi(isobutyronitrile) as a water-based paste” to the Self-Reactive Substances Table for substances that are not subject to the approval provisions of § 173.124(a)(2)(iii), provided all applicable provisions in the table are met. Finally, we would revise paragraph (b)(4) and remove paragraph (d) to allow Type F self-reaction substances to be transported in portable tanks under conditions specified in § 173.225(e) (see preamble discussion under § 173.225).

Section 173.225. We are proposing to amend the paragraph (b) Organic Peroxide Table by making various changes, such as revising several technical names, packing method authorizations and control temperatures. These proposed changes are consistent with the UN Recommendations. We are proposing to remove Notes “7” and “10” consistent with our proposed adoption of UN IBC 520 and add Notes “26” and “27” to specify the available oxygen content limitations for certain new organic peroxides formulations. We would revise paragraph (e) to incorporate the requirements from the eleventh revised edition of the UN Recommendations relevant to the emergency venting devices for portable tanks used for the transportation of organic peroxides and self-reactive substances. This responds to NTSB recommendation (I-92-2) that asked us to “revise the requirements for pressure relief venting on DOT specification 57 portable tanks used to transport dicumyl peroxides and other products with similar rapid decomposition characteristics to ensure that the pressure relief systems prevent overpressure rupture of tanks from a rapid product decomposition reaction.” We propose to apply the recommended venting requirements to all portable tanks and IBCs, rather than just DOT Specification portable tanks. Additionally, the types of portable tanks authorized for type F organic peroxide and self-reactive substances would be expanded to include UN portable tanks. We propose to adopt the requirements in Portable Tank Instruction T23 and IBC Special Provision , IBC 520.

Sections 173.240, 173.241, 173.242 and 173.243. In each section's paragraph (c), we would remove Specification DOT 52 and 53 portable tanks as authorized packagings (see § 173.32 ) because we believe that these portable tanks are no longer used. In addition, we would authorize UN portable tanks. In conjunction with the proposal to revise the requirements for IBCs for alignment with international standards, we would revise paragraph (d) which specifies authorized IBCs in §§ 173.240, 173.241, 173.242 and 173.243 to reflect the proposed incorporation of IBC packing instructions and BB codes (see § 172.101, Column (7)).

Section 173.247. In paragraph (c), we would remove Specification DOT 52 and 53 portable tanks as authorized packagings (see § 173.32).

Section 173.306. Consistent with Packing Instruction P201 in the UN Recommendations, we would amend the paragraph (a)(4)(iii) conditions for transporting flammable, non-pressurized gas samples by revising the inner packagings limit from 2.5 L (0.66 gallons) to 5 L (1.3 gallons).

Section 173.315. We would revise paragraphs (a) and (i) to incorporate provisions for the use of UN portable tanks for the transportation of liquefied compressed gases, in addition to the requirements for DOT Specification 51 portable tanks. Revisions would refer to tank instruction T50 (see UN T Codes under § 172.102) for the transportation of liquefied compressed gases in UN portable tanks and would include minor differences in pressure relief device requirements applicable to UN portable tanks.

Part 175

Section 175.10. For consistency with the ICAO Technical Instructions, we are proposing to revise paragraph (a)(10) to clarify that lighters containing “unabsorbed liquid fuel” are prohibited on one's person or in checked or carry-on baggage. We are proposing to revise exclusions for alcoholic beverages as carry-on and checked baggage to impose a per passenger quantity limit and to restrict the exceptions to alcoholic beverages in retail packagings containing not more than 70% alcohol. We are proposing to revise paragraph (a)(16) to exclude alcoholic beverages. Also, we are proposing to add new paragraph (a)(17) to specify that alcoholic beverages containing more than 24% and not more than 70% alcohol by volume, when carried by passengers or crew in checked or carry-on baggage, are not subject to the HMR if in retail packagings not exceeding 5 liters (1.3 gallons) with a total net quantity per person of 5 liters (1.3 gallons). These proposed changes are consistent with the ICAO Technical Instructions.

Section 175.33. For harmonization with the ICAO Technical Instructions, we would revise paragraph (a) introductory text to add a requirement that the written pilot notification must be accurate and legible.

Section 175.78. We would revise this section to update and align segregation requirements with recent changes adopted in the ICAO Technical Instructions which were based on a UN decision to remove the distinction between primary and subsidiary risk labels. Separate rows and columns would be provided for Divisions 5.1 and 5.2. We would add a new provision to clarify that packages with multiple risks would not need to be segregated from other packages bearing the same UN number.

Section 175.85. Consistent with a new provision adopted in the ICAO Technical Instructions, we would revise paragraph (a) to authorize main deck Class C cargo compartments. Currently, hazardous materials may be carried in a main deck cargo compartment of a passenger aircraft provided the compartment is inaccessible to passengers and it meets certification requirements for a Class B cargo compartment. (Class C cargo compartments differ from Class B cargo compartments in that Class C compartments are required to have a built-in fire extinguishing system, in addition to smoke or fire detection systems.)

Part 176

Section 176.2. In conjunction with the proposal to incorporate a requirement for vessel cargo to be in compliance with the INF Code (see § 176.720), we would add a definition for “INF cargo” under the § 176.2 definitions.

Section 176.63. For the stowage of Class 1 (explosive) materials on board a vessel, we would add a stowage location definition for “closed cargo transport unit.” This proposed addition coincides with the proposed addition of the vessel stowage category definitions contained in Amendment 30 to the IMDG Code. (See § 172.101(k).)

Section 176.84. Consistent with the IMDG Code we would revise paragraph (b) Table of provisions and paragraph (c)(2) stowage provisions. In the paragraph (b) Table of provisions, we would add two new stowage provisions for assignment to the entries, “Calcium hypochlorite, dry or Calcium hypochlorite mixtures dry with more than 39 percent available chlorine (8.8 percent available oxygen),” “Calcium hypochlorite, hydrated or Calcium hypochlorite hydrated mixtures with not less than 5.5 percent but not more than 10 percent water,” and “Calcium hypochlorite mixtures, dry with more than 10 percent but not more than 39 percent available chlorine.” In the paragraph (c)(2), we would revise the list of notes for the stowage of Class 1 (explosive) material provisions.

Section 176.128. We would make an editorial change in § 176.128(c) by correcting an identification number.

Section 176.136. We would make an editorial change in § 176.136 by removing the word “portable.”

Section 176.142. Based on a comment from the National Cargo Bureau, Inc., in § 176.142, paragraph (a), we would revise the list of hazardous materials that may not be transported in a vessel carrying Class 1 (explosive) materials to reflect the most current proper shipping names and to add one extremely flammable material, “Methyl phosphonous dichloride, pyrophoric liquid,” NA2845.

Section 176.720. We would add a new section to require a vessel carrying INF cargo in international transportation to comply with the “International Code for the Safe Carriage of Packaged Irradiated Nuclear Fuel, Plutonium and High-Level Radioactive Wastes on Board Ships,” (INF Code, 1998, English edition). The INF Code was adopted by the International Maritime Safety Committee and will be effective January 1, 2001 under the IMDG Code.

Part 177

Section 177.848. In paragraph (g)(3)(vi), we inadvertently added the terms “special stowage” and “stowed” from the corresponding vessel section of the HMR (§ 174.81) under HM-215C (64 FR 10742). In this NPRM, we propose to correct the wording by removing “special stowage,” which is not applicable to this section, and replacing “stowed” with “loaded, transported and stored.” We received a joint petition from the American Trucking Associations (ATA) and the Institute of Makers of Explosives (IME) (P-1396) requesting additional clarification of this paragraph. The paragraph reads:

“(vi) “6” means explosive articles in compatibility group G, other than fireworks and those requiring special stowage, may be stowed with articles of compatibility groups C, D and E, provided no explosive substances are carried in the same vehicle.”

In this paragraph and the corresponding paragraph in § 174.81, the petitioners request that the word “other” be inserted before the wording “explosive substances.” However, there is a distinction between the words “articles” and “substances.” This paragraph pertains to certain explosive articles allowed to be stowed if no explosive substances (not articles) are carried on the same vehicle.

Part 178

Section 178.273. We are proposing to add a new section by moving the current requirements for the approval of Specification portable tanks from § 173.32a to the proposed § 178.273. These current approval provisions will precede the requirements for UN portable tanks (as proposed in §§ 178.274 through 178.277).

Sections 178.274, 178.275, 178.276 and 178.277. Based on the eleventh revised edition of the UN Recommendations, we are proposing to incorporate four new sections into the HMR for the UN portable tank requirements. This proposed action is based on our own initiative and responds to a petition for rulemaking (P-1373). The requirements apply to the design and construction of portable tanks. The IMO Dangerous Goods, Solid Cargoes and Containers (DSC) Sub-Committee agreed to incorporate the new harmonized UN multimodal portable tank requirements into the reformatted IMDG Code, Amendment 30. The reformatted IMDG Code is scheduled to become effective on January 1, 2001. The IMDG Code also includes a provision to allow for the continued use of portable tanks designed and constructed under the current requirements (those in Amendments 29 or previous amendments to the IMDG Code as applicable, depending on the date of construction).

The IMO intends to allow construction under the new requirements on January 1, 2001, on a voluntary compliance basis, with a mandatory compliance date of January 1, 2003. On January 1, 2003, all new portable tanks will be required to be manufactured in accordance with the new requirements. For purposes of harmonization, we are proposing to incorporate the corresponding design, construction and use requirements for UN portable tanks in the HMR. In addition, in § 173.32 we are proposing to provide for the continued use of IM 101, 102 and DOT Specification 51 portable tanks, which is consistent with the provisions adopted by the IMO.

The design and construction requirements for UN portable tanks do not differ significantly from the existing IM 101 and 102 portable tanks and the DOT Specification 51 requirements. In general, the UN requirements are less restrictive. For example, 6 mm (0.2 inches) minimum thickness is required for most portable tanks, as opposed to the current minimum thickness of 6.35 mm (0.3 inches) for IM 101 and 102 portable tanks. While the majority of the proposed changes involve relaxations of the regulatory requirements, there would be implications for portable tank manufacturers, shippers and operators who transport hazardous materials in portable tanks, and efforts would need to be undertaken to familiarize those affected with the differences. For example, we would require UN portable tanks used for the transportation of liquefied compressed gases to be approved by a DOT-designated approval agency, and we would require all UN portable tanks to meet a 4 g impact test. In addition to portable tanks for liquids and liquefied compressed gases, we propose to incorporate requirements for portable tanks that are used to transport refrigerated liquified gases (cryogenic liquids). Currently, requirements for portable tanks used for refrigerated liquefied gases are not specified in the HMR, and we authorize their use only under DOT exemptions. The differences between UN portable tanks and the current portable tank requirements include, but are not limited to the following:

—The proposed definition for portable tank includes multimodal tanks with a capacity of more than 450 liters (118.9 gallons). Previously, IMO Type 5 and DOT Specification 51 tanks intended for the transport of liquefied compressed gases were limited to a capacity of more than 1000 liters (264.2 gallons).

—The proposed design temperature range is defined as −40 °C to 50 °C (−40 °F to 122.0 °F). This NPRM also proposes design temperatures to be considered for portable tanks subjected to severe climatic conditions. Current regulations specify −20 °C to 50 °C (−4.0 °F to 122.0 °F).

—The proposed UN leakage test for liquids specifies a test pressure not less than 25% of Maximum Allowable Working Pressure (MAWP). The current HMR requirements specify an internal pressure equivalent to MAWP, but not less than 0.2 bar (20.0 kPa) for liquids.

—The proposed test requires that the design and construction of portable tanks must take into account the effects of fatigue during normal conditions of transport. Currently, this is not required in the HMR.

—The proposed requirements specify an absolute minimum thickness of 3 mm (0.1 inches), regardless of the material used and regardless of whether additional protection is provided.

—A rail impact test of 4 g would be required for all portable tanks meeting the definition of “Container” in the International Convention for Safe Containers (CSC).

—The proposed requirements specify that the test pressure be 1.3 times the design pressure. Currently, under the HMR, DOT 51 portable tanks are required to have a test pressure of 1.5 times the design pressure; however, this is based on the vapor pressure of the hazardous material at 115 °F (46.1 °C), whereas the UN calculates the vapor pressure at 65 °C (149 °F). Therefore, the differences between 1.5 at 46 °C and 1.3 at 65 °C would not be significant.

—The proposed requirements include a figure for thermal conductance for the thermal insulation systems of shells intended for the transport of liquefied compressed gases.

—The proposed requirements include a definition for “Holding time” relevant to portable tanks used for the transportation of refrigerated liquefied gases. This is consistent with current HMR requirements in § 178.338-9 for cargo tanks.

—The proposed requirements specify the effectiveness of the insulation system (heat influx in watts) based on a test using the portable tank.

—The proposal allows the specified minimum values for austenitic steels to be increased by 15% according to recognized material standards when greater values are provided in the material inspection certificates.

—The proposed requirements allow the combined capacity of all pressure relief devices to be sufficient to limit the pressure to 120% of the MAWP for liquefied compressed gases.

—The proposed requirements include a new filling limit for the transport of helium.

Based on the above discussion (§§ 178.273 through 178.277), five new sections are proposed to be added as follows: § 178.273 would be added by moving the current requirements for the approval of Specification portable tanks from § 173.32a and introducing similar requirements for UN portable tanks; § 178.274 would be added for the UN portable tank general design and construction requirements; § 178.275 would be added for the additional specifications for UN portable tanks intended for the transportation of liquid and solid materials of Classes 3 through 9; § 178.276 would be added for the additional requirements for UN portable tanks intended for the transportation of liquefied compressed gases; and § 178.277 would be added for the additional requirements for the design, construction, inspection and testing of UN portable tanks intended for the transport of refrigerated liquefied gases.

Section 178.703. Paragraph (a)(1) would be revised by incorporating a minimum height of 12 mm (0.5 inches) for IBC markings and by adding a requirement to allow use of the “W” mark for approval of equivalent IBC packagings, as provided for in § 178.801(i).

Section 178.705. We are proposing to revise the minimum wall thickness requirements to take into account the capacity of the IBC, as well as the IBC design type.

Section 178.801. In paragraph (i), we are proposing to add an approval provision for the use of large packagings, as defined in § 171.8 of this NPRM, provided the large packagings conform to the construction standards, performance testing and packaging marking as specified in UN Recommendations.

Section 178.812. Based on our own initiative, we would revise paragraph (c)(1) and add a new paragraph (c)(3) to add an alternate method for conducting the top lift test for flexible IBCs. Currently, the proposed alternate method is authorized in several approvals issued by the Associate Administrator.

Part 180

Sections 180.601, 180.603, 180.605. We propose to move the qualification and maintenance requirements for portable tanks to part 180. We believe that these requirements would be more appropriately placed in part 180 along with the qualification and maintenance requirements for cargo tanks, IBCs and tank cars. Therefore, we propose to add a new subpart, subpart G, to part 180 for the qualification and maintenance of portable tanks, and to include the incorporation of UN portable tanks as proposed in this NPRM.

IV. Rulemaking Analyses and Notices

A. Executive Order 12866 and DOT Regulatory Policies and Procedures

This proposed 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 proposed rule is not considered a significant rule under the Regulatory Policies and Procedures of the Department of Transportation [44 FR 11034]. Because of the minimal economic impact of this proposed rule, preparation of a regulatory impact analysis or regulatory evaluation is not warranted.

B. Executive Order 13132

This proposed rule has been analyzed in accordance with the principles and criteria contained in Executive Order 13132 (“Federalism”). This proposed rule would preempt State, local and Indian tribe requirements but does not propose any regulation that has substantial direct effects on the States, the relationship between the national government and the States, or the distribution of power and responsibilities among the various levels of government. Therefore, the consultation and funding requirements of Executive Order 13132 do not apply.

The Federal hazardous material transportation law, 49 U.S.C. 5101-5127, contains an express preemption provision (49 U.S.C. 5125(b)) that preempts State, local, and Indian tribe requirements on certain covered subjects. Covered subjects are:

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

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

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

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

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

This proposed rule addresses covered subject items (1), (2), (3), and (5) above and would preempt State, local, and Indian tribe requirements not meeting the “substantively the same” standard. This proposed rule is necessary to incorporate changes already adopted in international standards. If the changes proposed in this NPRM are not adopted in the HMR, U.S. companies, including numerous small entities competing in foreign markets, will be at an economic disadvantage. These companies would be forced to comply with a dual system of regulation. The proposed changes are intended to avoid this result.

Federal hazardous materials transportation law provides at 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 may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. Thus, RSPA lacks discretion in this area. RSPA proposes that the effective date of Federal preemption will be 180 days from publication of a final rule in this matter in the Federal Register.

C. Executive Order 13084

This proposed rule has been analyzed in accordance with the principles and criteria contained in Executive Order 13084 (“Consultation and Coordination with Indian Tribal Governments”). Because this proposed rule does not significantly or uniquely affect the communities of the Indian tribal governments and does not impose substantial direct compliance costs, the funding and consultation requirements of Executive Order 13084 do not apply.

D. Regulatory Flexibility Act

This proposed rule would incorporate changes introduced in the eleventh revised edition of the UN Recommendations, the 2001-2002 ICAO Technical Instructions, and Amendment 30 to the IMDG Code. It would apply to offerors and carriers of hazardous materials and would facilitate the transportation of hazardous materials in international commerce by providing consistency with international requirements.

The costs associated with this proposed rule are considered to be so minimal as to not warrant preparation of a regulatory impact analysis or regulatory evaluation. The majority of amendments should result in cost savings and would ease the regulatory compliance burden for shippers engaged in international commerce, including trans-border shipments within North America. For example, cost savings will be realized by shippers and carriers as a result of eliminating the differences between primary and subsidiary labels. As a result of this change, it will no longer be necessary to stock two sets of labels for each hazard class. To ease any burden associated with this change, we are proposing a reasonable transition period where labels meeting current and proposed requirements may be used. Other cost savings include: revising minimum thickness requirements for metal IBCs; providing greater harmonization with international regulations and flexibility for IBCs and portable tanks that may be used for the transportation of hazardous materials; authorizing the use of UN portable tanks while retaining current IM 101, 102 and DOT Specification 51 portable tank requirements and authorizations for their use; numerous deletions from the hazardous materials table and the marine pollutant list; more flexible requirements for transporting samples of hazardous materials; authorization to use a single explosives placard when explosives of several compatibility groups are transported in a single freight container or vehicle; several clarifications of existing regulatory requirements; and revised requirements for large lithium batteries which will simplify the regulatory requirements applicable to batteries used in high energy efficient hybrid vehicles. We are proposing immediate voluntary compliance (as of January 1, 2001 or the date of publication of the final rule, whichever occurs first), a delayed effective date and a one-year transition period to allow for training of employees and to ease any burden on entities affected by the proposed amendments. Many companies involved in domestic, as well as global operations, will realize economic benefits as a result of the proposed amendments in this rulemaking. Therefore, I certify that this proposed rule will not, if promulgated, have a significant economic impact on a substantial number of small entities. This certification is subject to modification as a result of a review of comments received in response to this proposal.

E. Paperwork Reduction Act

We have current information collection approvals under OMB No. 2137-0557, Approvals for Hazardous Materials, which expires March 31, 2002, with 18,302 burden hours and $413,737.40 annual costs, and OMB No. 2137-0018, Inspection and Testing of Portable Tanks and Intermediate Bulk Containers, which expires March 31, 2002, with 51,340 burden hours and $10,235,000 annual costs. We believe that this proposed rule may result in minor incremental increases in the annual burden hours and costs. If these proposals are finalized, the current approvals would be revised and resubmitted to OMB for extension and re-approval.

Section 1320.8(d), Title 5, Code of Federal Regulations requires that RSPA provide interested members of the public and affected agencies an opportunity to comment on information collection and recordkeeping requests. This notice identifies information collections that we may submit to OMB for extension and re-approval based on the requirements in this proposed rule. We have revised burden estimates, where appropriate, to reflect current reporting levels or adjustments based on changes in this proposed rule since the information collections were last approved. We estimate that the total information collection and recordkeeping burdens as proposed in this rule would be revised as follows:

We specifically request comments on the information collection and recordkeeping burdens associated with developing, implementing, and maintaining these requirements for approval under this proposed rule.

Requests for a copy of the information collection approvals, requests and data should be directed to Deborah Boothe, Office of Hazardous Materials Standards (DHM-10), Research and Special Programs Administration, Room 8102, 400 Seventh Street, SW, Washington, DC 20590-0001, Telephone [phone].

Written comments should be addressed to the Dockets Management System as identified in the ADDRESSES section of this rulemaking. Comments should be received prior to the close of comment period identified in the DATES section of this rulemaking. Under the Paperwork Reduction Act of 1995, no person is required to respond to an information collection unless it displays a valid OMB control number. If these proposed requirements are adopted in a final rule, we will submit the revised information collection and recordkeeping requirements to the Office of Management and Budget for approval.

F. 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.

G. Unfunded Mandates Reform Act

This proposed rule does not impose unfunded mandates under the Unfunded Mandates Reform Act of 1995. It does not result in costs of $100 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 objective of the rule.

13. In Appendix B to § 172.101, paragraphs 1. and 2. would be revised and the List of Marine Pollutants would be amended by removing 73 entries, adding 2 entries and revising 2 entries in appropriate alphabetical order to read as follows:

Appendix B to § 172.101—List of Marine Pollutants

1. See § 171.4 of this subchapter for applicability of marine pollutants. This appendix lists potential marine pollutants as defined in § 171.8 of this subchapter.

2. Marine pollutants listed in this appendix are not necessarily listed by name in the § 172.101 Table. If a marine pollutant not listed by name or by synonym in the § 172.101 Table meets the definition of any hazard Class 1 through 8, then you must determine the class and division of the material in accordance with § 173.2a of this subchapter. You must also select the most appropriate hazardous material description and proper shipping name. If a marine pollutant not listed by name or by synonym in the § 172.101 Table does not meet the definition of any Class 1 through 8, then you must offer it for transportation under the most appropriate of the following two Class 9 entries: “Environmentally hazardous substances, liquid, n.o.s.,” UN3082, or “Environmentally hazardous substances, solid, n.o.s.,” UN3077.

Portable tank instructions specify the requirements applicable to a portable tank when used for the transportation of a specific hazardous material. These requirements must be met in addition to the design and construction specifications in part 178 of this subchapter. Portable tank instructions T1 through T22 specify the applicable minimum test pressure, the minimum shell thickness (in reference steel), bottom opening requirements and pressure relief requirements. In T23, the organic peroxides and self-reactive substances which are authorized to be transported in portable tanks are listed along with the applicable control and emergency temperatures. Liquefied compressed gases are assigned to portable tank instruction T50. T50 provides the maximum allowable working pressures, bottom opening requirements, pressure relief requirements and degree of filling requirements for liquefied compressed gases permitted for transport in portable tanks. Refrigerated liquefied gases which are authorized to be transported in portable tanks are specified in tank instruction T75.

(ii) The following table specifies the portable tank requirements applicable to T Codes T1 through T22. Column 1 specifies the T Code. Column 2 specifies the minimum test pressure, in bar (1 bar = 14.5 psig), at which the periodic hydrostatic testing required by § 173.32b of this subchapter must be conducted. Column 3 specifies the section reference for minimum shell thickness or, alternatively, the minimum shell thickness value. Column 4 specifies the applicability of § 178.275(f)(3) of this subchapter for the pressure relief devices. When the word “Normal” is indicated, § 178.275(f)(3) of this subchapter does not apply.

25. Section 173.32 would be revised to read as follows:

§ 173.32

Requirements for the use of portable tanks.

(a) General requirements. No person may offer a hazardous material for transportation in a portable tank except as authorized by this subchapter.

(1) Except as otherwise provided in this subpart, a portable tank may not be used for the transportation of a hazardous material unless it meets the requirements of this subchapter.

(2) No person may fill and offer for transportation a portable tank when the prescribed periodic test or inspection under subpart G of part 180 of this subchapter has become due until the test or inspection has been successfully completed. This requirement does not apply to any portable tank filled prior to the test or inspection due date.

(3) When a portable tank is used as a cargo tank container, it shall conform to all the requirements prescribed for cargo tank containers. (See § 173.33.)

(b) Substitute packagings. A particular Specification portable tank may be substituted for another portable tank as follows:

(1) An IM or UN portable tank may be used whenever an IM or UN portable tank having less stringent requirements is authorized provided the portable tank meets or exceeds the requirements for pressure-relief devices, bottom outlets and any other special provisions specified in § 172.102(c)(7)(vi) of this subchapter.

(2) Where a Specification IM101 or IM102 portable tank is prescribed, a Specification 51 portable tank otherwise conforming to the special commodity requirements of § 172.102(c)(7) of this subchapter may be used.

(3) A DOT Specification 51 portable tank may be used whenever a DOT Specification 56, 57, or 60 portable tank is authorized. A DOT Specification 60 portable tank may be used whenever a DOT Specification 56 or 57 portable tank is authorized. A higher integrity tank used instead of a specified portable tank must meet the same design profile; for example, a DOT Specification 51 portable tank must be lined if used instead of a lined DOT Specification 60 portable tank.

(c) Grandfather provisions for portable tanks— (1) Continued use of specification 56 and 57 portable tanks. Continued use of an existing portable tank constructed to DOT Specification 56 or 57 is authorized only for a tank constructed before October 1, 1996. A stainless steel portable tank internally lined with polyethylene that was constructed on or before October 1, 1996, and that meets all requirements of DOT Specification 57 except for being equipped with a polypropylene discharge ball valve and polypropylene secondary discharge opening closure, may be marked as a Specification 57 portable tank and used in accordance with the provisions of this section.

(2) A DOT Specification 51 and IM 101 or IM 102 portable tank may not be manufactured after January 1, 2003 may continue to be used for the transportation of a hazardous material provided they fulfill the requirements of this subchapter, including the specification requirements and the requirements of this subchapter for the transportation of the particular hazardous material (see § 171.14(d)(5) of this subchapter), and provided it conforms to the periodic inspection and tests specified for the particular portable tank in subpart G of part 180 of this subchapter. On and after January 1, 2003, all newly manufactured portable tanks must conform to the requirements for the design, construction and approval of UN portable tanks as specified in §§ 178.273, 178.274, 178.275, 178.276 and 178.277 of this subchapter.

(3) A DOT Specification portable tank manufactured prior to January 1, 1992 that is equipped with a non-reclosable pressure relief device may continue in service for the hazardous materials for which it is authorized. Except for a DOT Specification 56 or 57 portable tank, a DOT Specification portable tank manufactured after January 1, 1992, used for materials meeting the definition for Division 6.1 liquids, Packing Group I or II, Class 2 gases, or Class 3 or 4 liquids, must be equipped with a re-closing pressure relief valve having adequately sized venting capacity.

(d) Maximum Allowable Working Pressure. (1) Prior to filling and offering a portable tank for transportation, the shipper must confirm that the portable tank conforms to the specification required for the hazardous material and that the maximum allowable working pressure (MAWP) of the portable tank is greater than or equal to the highest pressure obtained under the following conditions:

(i) For compressed gases and certain refrigerated liquids that are not cryogenic liquids and that are not transported in a UN portable tank, the pressure prescribed in § 173.315. For liquefied compressed gases transported in a UN portable tank, the pressures prescribed in T50 in § 172.102 of this subchapter.

(ii) For liquid hazardous materials the pressures specified in § 178.275(a) of this subchapter used for determining the MAWP.

(iii) The maximum pressure used to load or unload the hazardous material.

(2) Unless otherwise specified, where a portable tank is authorized, the minimum tank design pressure is 172 kPa (25 psig) for any Packing Group I or Packing Group II liquid hazardous material that meets more than one hazard class definition.

(e) External inspection prior to filling. Each portable tank must be given a complete external inspection. Any unsafe condition must be corrected prior to its being offered for transportation. The external inspection shall include a visual inspection of:

(1) The shell, piping, valves and other appurtenances for corroded areas, dents, defects in welds and other defects such as missing, damaged, or leaking gaskets;

(2) All flanged connections or blank flanges for missing or loose nuts and bolts;

(3) All emergency devices for corrosion, distortion, or any damage or defect that could prevent their normal operation;

(4) All required markings on the tank for legibility; and

(5) Any device for tightening manhole covers to ensure such devices are operative and adequate to prevent leakage at the manhole cover.

(f) Loading requirements. (1) A hazardous material may not be loaded in a portable tank if the part of the tank or any of its appurtenances having contact with the material during transportation would be damaged, would cause a dangerous reaction with the material or would compromise the ability of the portable tank to retain the hazardous material.

(2) A hazardous material may not be loaded in a portable tank unless it has pressure relief devices providing total relieving capacity meeting the requirements of this subchapter.

(3) Except during a hydrostatic test, a portable tank may not be subjected to a pressure greater than its maximum allowable working pressure.

(4) A portable tank may not be loaded to a gross weight greater than the maximum allowable gross weight specified on its identification plate.

(5) Except for a non-flowable solid or a liquid with a viscosity of 2,680 centistokes (millimeters squared per second) or greater at 20°C (68 °F), a portable tank or compartment thereof having a volume greater than 7,500 L (1,980 gallons) may not be loaded to a filling density of more than 20% and less than 80% by volume. This filling restriction does not apply if a portable tank is divided by partitions or surge plates into compartments of not more than 7,500 L (1,980) capacity. Portable tanks must not be offered for transportation in an ullage condition liable to produce an unacceptable hydraulic force due to surge.

(6) The outage for a portable tank may not be less than 2% at a temperature of 50 °C (122 °F). For UN portable tanks, the applicable maximum filling limits apply as specified according to the assigned TP codes in Column (7) of the § 172.101 Table of this subchapter except when transported domestically.

(7) Each tell-tale indicator for the space between a frangible disc and a safety relief valve mounted in series must be checked after the tank is filled and prior to transportation to ensure that the frangible disc is leak free. Any leakage through the frangible disc must be corrected prior to offering the tank for transportation. The tell-tale device must be designed to prevent the loss of any hazardous material through the device itself while the tank is in transportation.

(8) During filling, the temperature of the hazardous materials shall not exceed the limits of the design temperature range of the portable tank.

(9) The maximum mass of liquefied compressed gas per liter (gallon) of shell capacity (kg/L or lbs./gal.) may not exceed the density of the liquefied compressed gas at 50 °C (122 °F). The portable tank must not be liquid full at 60 °C (140 °F).

(g) Relief system. Any DOT Specification portable tank manufactured prior to January 1, 1992 that is equipped with a non-reclosable pressure relief device may continue in service for the hazardous materials for which it it is authorized. Except for DOT Specification 56 and 57 portable tanks, any DOT Specification portable tank manufactured after January 1, 1992 used for materials meeting the definition for Division 6.1 liquids Packing Group I or II, Class 2 gases, or Class 3 or 4 liquids must be equipped with a reclosing pressure relief valve having adequately sized venting capacity.

(h) Additional requirements for specific modal transport. In addition to other applicable requirements, the following apply:

(1) A portable tank containing a hazardous material may not be loaded on a highway or rail transport vehicle unless loaded entirely within the horizontal outline thereof, without overhang or projection of any part of the tank assembly. In addition, for unloading a portable tank, see § 177.834(h) of this subchapter.

(2) A portable tank used for the transportation of flammable liquids by rail may not be fitted with non-reclosing pressure relief devices except in series with reclosing pressure relief valves.

(3) A portable tank or Specification 106A or 110A multi-unit tank car containing a hazardous material may not be offered for transportation aboard a passenger vessel unless:

(i) The vessel is operating under a change to its character of vessel certification as defined in § 171.8 of this subchapter; and

(ii) The material is permitted to be transported aboard a passenger vessel in the § 172.101 Table of this subchapter.

(i) Additional general commodity specific requirements. In addition to other applicable requirements, the following requirements apply:

(1) Each uninsulated portable tank used for the transportation of liquefied compressed gases must have an exterior surface finish that is significantly reflective, such as a light-reflecting color if painted, or a bright reflective metal or other material if unpainted.

(2) If a hazardous material is being transported in a molten state, the portable tank must be thermally insulated with suitable insulation material of sufficient thickness that the overall thermal conductance is not more than 0.080 Btu per hour per square foot per degree Fahrenheit differential.

(j) Additional requirements for portable tanks other than IM specification and UN portable tanks. (1) The bursting strength of any piping and fittings must be at least four times the design pressure of the tank, and at least four times the pressure to which, in any instance, it may be subjected in service by the action of a pump or other device (not including safety relief valves) that may subject piping to pressures greater than the design pressure of the tank.

(2) Pipe joints must be threaded, welded or flanged. If threaded pipe is used, the pipe and pipe fittings must not be lighter than (Schedule 80) weight. Non-malleable metals must not be used in the construction of valves or fittings. Where copper tubing is permitted, joints must be brazed or be of equally strong metal union type. The melting point of brazing material may not be lower than 1,000 °F (537.8°C). The method of joining tubing must not decrease the strength of the tubing such as by the cutting of threads.

(3) Non-malleable metals may not be used in the construction of valves or fittings.

(4) Suitable provision must be made in every case to allow for expansion, contraction, jarring and vibration of all pipe. Slip joints may not be used for this purpose.

(5) Piping and fittings must be grouped in the smallest practicable space and must be protected from damage as required by the specification.

(6) All piping, valves and fittings on every portable tank must be leakage tested with gas or air after installation and proved tight at not less than the design pressure of the portable tank on which they are used. In the event of replacement, all such piping, valves, or fittings so replaced must be tested in accordance with the requirements of this section before the portable tank is returned to transportation service. The requirements of this section apply to all hoses used on portable tanks, except that hoses may be tested either before or after installation on the portable tank.

(7) All materials used in the construction of portable tanks and their appurtenances may not be subject to destructive attack by the contents of the tank.

(8) All parts of the portable tanks and appurtenances for anhydrous ammonia must be steel. No aluminum, copper, silver, zinc, nor their alloys may be used. Brazed joints may not be used.

(9) Each outlet of a portable tank used for the transportation of liquefied compressed gases, except carbon dioxide, must be provided with a suitable automatic excess-flow valve (see definition in § 178.337-1(g) of this subchapter). These valves must be located inside the portable tank or at a point outside the portable tank where the line enters or leaves the portable tank. The valve seat must be located inside the portable tank or may be located within a welded flange or its companion flange, or within a nozzle or within a coupling. The installation must be made in such a manner as to reasonably assure that any undue strain which causes failure requiring functioning of the valve shall cause failure in such a manner that it will not impair the operation of the valve.

(i) Safety device connections and liquid level gauging devices that are constructed so that the outward flow of tank contents willl not exceed that passed by an opening of 0.1397 cm (0.0550 inches) are not required to be equipped with excess-flow valves.

(ii) An excess-flow valve must close automatically if the flow reaches the rated flow of gas or liquid specified by the original valve manufacturer when piping mounted directly on the valve is sheared off before the first valve, pump, or fitting downstream from the excess flow valve.

(iii) An excess-flow valve may be designed with a by-pass, not to exceed a 0.1016 cm (0.040 inches) diameter opening to allow equalization of pressure.

(iv) Filling and discharge lines must be provided with manually operated shut-off valves located as close to the tank as practical. The use of “Stop-Check” valves to satisfy with one valve the requirements of this section is forbidden.

(10) Each portable tank used for carbon dioxide and nitrous oxide must be lagged with a suitable insulation material of such thickness that the overall thermal conductance is not more than 0.08 Btu per square foot per degree Fahrenheit differential in temperature per hour. The conductance must be determined at 60° Fahrenheit. Insulation material used on portable tanks for nitrous oxide must be noncombustible.

(11) A refrigerating and/or heating coil or coils must be installed in portable tanks used for carbon dioxide and nitrous oxide. Such coils must be tested externally to at least the same pressure as the test pressure of the portable tank. The coils must also be tested internally to at least twice the working pressure of the heating or refrigerating system to be used, but in no case less than the test pressure of the portable tank. Such coils must be securely anchored. The refrigerant or heating medium to be circulated through the coil or coils must be such as to cause no adverse chemical reaction with the portable tank or its contents in the event of leakage.

(e) Bulk packagings for organic peroxides. The following bulk packagings are authorized:

* * * * *

(3) Portable tanks. The following requirements apply to portable tanks intended for the transport of Type F organic peroxides or Type F self-reactive substances. DOT 51, 57, IM 101 portable tanks, and UN portable tanks that conform to the requirements of T23 (see § 172.102(c)(7) of this subchapter), when T23 is specified in Column (7) of the § 171.101 Table of this subchapter for the Type F organic peroxide or Type F self-reactive substance. Type F organic peroxide or self-reactive substance formulations other than those indicated in T23 may be transported in portable tanks if approved by the Associate Administrator. The following conditions also apply:

(i) The portable tank must be designed for a test pressure of at least 0.4 MPa (4 bar).

(ii) Portable tanks must be fitted with temperature-sensing devices.

(iii) Portable tanks must be fitted with pressure relief devices and emergency-relief devices. Vacuum-relief devices may also be used. Pressure relief devices must operate at pressures determined according to both the properties of the hazardous material and the construction characteristics of the portable tank. Fusible elements are not allowed in the shell.

(iv) The pressure relief devices must consist of reclosing devices fitted to prevent significant build-up within the portable tank of the decomposition products and vapors released at a temperature of 50 °C (122 °F). The capacity and start-to-discharge pressure of the relief devices must be in accordance with the applicable requirements of this subchapter specified for the portable tank. The start-to-discharge pressure must in no case be such that liquid would escape from the pressure relief devices if the portable tank were overturned.

(v)(A) The emergency-relief devices may be of the reclosing or frangible types, or a combination of the two, designed to vent all the decomposition products and vapors evolved during a period of not less than one hour of complete fire engulfment as calculated by the following formula:

Where:

q = heat absorption (W)

A = wetted area (m²)

(B) Insulation factor (F) in the formula in paragraph (e)(3)(v)(A) of this section equals 1 for non-insulated vessels and for insulated vessels F is calculated using the following formula:

Where:

U = K/L = heat transfer coefficient of the insulation (W·m⁻²·K⁻¹); where K = heat conductivity of insulation layer (W·m⁻¹·K⁻¹), and L = thickness of insulation layer (m).

T_PO = temperature of material at relieving conditions (K).

(vi) The start-to-discharge pressure of emergency-relief devices must be higher than that specified for the pressure relief devices in paragraph (e)(3)(iv) of this section. The emergency-relief devices must be sized and designed in such a way that the maximum pressure in the shell never exceeds the test pressure of the portable tank.

Note to Paragraph (e)(3)(vi):

An example of a method to determine the size of emergency-relief devices is given in Appendix 5 of the UN Manual of Tests and Criteria (incorporated by reference, see § 171.7 of this subchapter).

(vii) For insulated portable tanks, the capacity and setting of emergency-relief devices must be determined assuming a loss of insulation from 1 percent of the surface area.

(ix) Vacuum-relief devices and reclosing devices on portable tanks used for flammable hazardous materials must be provided with flame arresters. Any reduction of the relief capacity caused by the flame arrester must be taken into account and the appropriate relief capacity must be provided.

(x) Service equipment such as devices and external piping must be designed and constructed so that no hazardous material remains in them after filling the portable tank.

(xi) Portable tanks may be either insulated or protected by a sun-shield. If the SADT of the hazardous material in the portable tank is 55 °C (131 °F) or less, the portable tank must be completely insulated. The outer surface must be finished in white or bright metal.

(xii) The degree of filling must not exceed 90% at 15 °C (59 °F).

(xiii) DOT 57 metal portable tanks are authorized only for tert-butyl cumyl peroxide, di-(2-tert-butylperoxyisopropyl-benzene(s), dicumyl peroxide and mixtures of two or more of these peroxides.

* * * * *

(5) IBCs. IBCs are authorized subject to the conditions and limitations of this section provided the IBC type is authorized according to IB52 (see 172.102(c)(4) of this subchapter), as applicable, and the IBC conforms to the requirements in part 178 of this subchapter at the Packing Group II performance level. The following additional requirements also apply:

(i) IBCs shall be provided with a device to allow venting during transportation. The inlet to the pressure relief device shall be sited in the vapor space of the IBC under maximum filling conditions during transportation.

(ii) To prevent explosive rupture of metal IBCs or composite IBCs with complete metal casing, the emergency-relief devices shall be designed to vent all the decomposition products and vapors evolved during self-accelerating decomposition or during a period of not less than one hour of complete fire-engulfment as calculated by the formula in paragraph (e)(3)(v) of this section. The control and emergency temperatures specified in IB52 are based on a non-insulated IBC.

47. Section 175.78 would be revised to read as follows:

§ 175.78

Stowage compatibility of cargo.

(a) For stowage on an aircraft, in a cargo facility, or in any other area at an airport designated for the stowage of hazardous materials, packages containing hazardous materials which might react dangerously with one another may not be placed next to each other or in a position that would allow a dangerous interaction in the event of leakage.

(b) As a minimum, the segregation instructions prescribed in the following Segregation Table must be followed to maintain acceptable segregation between packages containing hazardous materials with different hazards. The Segregation Table instructions in paragraph (c) of this section apply whether or not the class or division is the primary or subsidiary risk. The Segregation Table follows:

Segregation Table

Hazard label	Class or division
	1	2	3	4.2	4.3	5.1	5.2	8
1	Note 1	Note 2	Note 2	Note 2	Note 2	Note 2	Note 2	Note 2
1	Note 2
2	Note 2
3	Note 2					X
4.2	Note 2					X
4.3	Note 2					X		X
5.1	Note 2		X	X
5.2	Note 2
8	Note 2				X

(c) Instructions for using the Segregation Table are as follows:

(1) The dots at the intersection of a row and column indicate that no restrictions apply.

(2) The letter “X” at the intersection of a row and column indicates that packages containing these classes of hazardous materials may not be stowed next to or in contact with each other, or in a position which would allow interaction in the event of leakage of the contents.

(3) Note 1. “Note 1” at the intersection of a row and column means the following:

(i) For explosives in compatibility groups A through K and N—

(A) Packages bearing the same compatibility group letter and the same division number may be stowed together.

(B) Explosives of the same compatibility group, but different divisions may be stowed together provided the whole shipment is treated as belonging to the division having the smaller number. However, when explosives of Division 1.5 Compatibility Group D are stowed together with explosives of Division 1.2 Compatibility Group D, the whole shipment must be treated as Division 1.1, Compatibility Group D.

(C) Packages bearing different compatibility group letters may not be stowed , whether or not they belong to the same division, except as provided in paragraphs (c)(3)(ii) and (iii) of this section.

(ii) Explosives in Compatibility Group L may not be stowed with explosives in other compatibility groups. They may only be stowed with the same type of explosives in Compatibility Group L.

(iii) Explosives of Division 1.4, Compatibility Group S, may be stowed with explosives of all compatibility groups except for Compatibility Groups A and L.

(iv) Other than explosives of Division 1.4, Compatibility Group S (see paragraph (c)(3)(iii) of this section), and Compatibility Groups C, D and E that may be stowed together, explosives that do not belong in the same compatibility group may not be stowed together.

(A) Any combination of substances in Compatibility Groups C and D must be assigned to the most appropriate compatibility group shown in the § 172.101 Hazardous Materials Table.

(B) Explosives in Compatibility Group N may be stowed together with explosives in Compatibility Groups C, D and E when the combination is assigned Compatibility Group D.

(4) Note 2. “Note 2” at the intersection of a row and column means that other than explosives of Division 1.4, Compatibility Group S, explosives may not be stowed together with that class.

(5) Packages containing hazardous materials with multiple hazards in the class or divisions, which require segregation in accordance with the Segregation Table need not be segregated from other packages bearing the same UN number.

(6) A package labeled “BLASTING AGENT” may not be stowed next to or in a position that will allow contact with a package of special fireworks or railway torpedoes.

48. In § 175.85 paragraph (a) would be revised to read as follows:

§ 175.85

Cargo location.

(a) Except as provided in § 175.10, no person may carry a hazardous material subject to the requirements of this subchapter in the cabin of a passenger-carrying aircraft or on the flight deck of any aircraft. Hazardous materials may be carried in a main deck cargo compartment of a passenger aircraft provided that the compartment is inaccessible to passengers and that it meets all certification requirements for a Class B aircraft cargo compartment in 14 CFR 25.857(b) or for a Class C aircraft cargo compartment in 14 CFR 25.857(c).

In addition to the requirements of this section, requirements specific to UN portable tanks used for liquid and solid hazardous materials, liquefied compressed gases and refrigerated liquefied gases are provided in §§ 178.275, 178.276 and 178.277, respectively. Requirements for approval, maintenance, inspection, testing and use are provided in § 178.273 and part 180, subpart G, of this subchapter. Any portable tank which meets the definition of a “container” within the terms of the International Convention for Safe Containers (CSC) must meet the requirements of the CSC as amended and 49 CFR parts 450 through 453 and must have a CSC safety approval plate.

(2) In recognition of scientific and technological advances, the technical requirements applicable to UN portable tanks may be varied if approved by the Associate Administrator and the portable tank is shown to provide a level of safety equal to or exceeding the requirements of this subchapter with respect to the compatibility of the transported hazardous materials and the ability of the portable tank to withstand impact, loading and fire conditions. Portable tanks approved to alternative technical requirements must be marked “Alternative Arrangement” as specified in paragraph (i) of this section.

(3) Definitions. The following definitions apply for the purposes of design and construction of UN portable tanks under this subpart:

Alternate Arrangement portable tank means a UN portable tank that has been approved to alternative technical requirements or testing methods other than those specified for UN portable tanks in part 178 or part 180 of this subchapter.

Approval agency means the designated approval agency authorized to approve the portable tank in accordance with the procedures in subpart E, part 107 of this subchapter.

Design pressure is defined differently depending on the hazardous materials intended to be transported in the portable tank. See §§ 178.275, 178.276 and 178.277 as applicable.

Design type means a portable tank or series of portable tanks made of materials of the same material specifications and thicknesses, manufactured by a single manufacturer, using the same fabrication techniques (for example, welding procedures) and made with equivalent structural equipment, closures, and service equipment.

Fine grain steel means steel which has a ferritic grain size of 6 or finer when determined in accordance with ASTM E 112 (incorporated by reference, see § 171.7 of this subchapter).

Jacket means the outer insulation cover or cladding which may be part of the insulation system.

Leakage test means a test using gas to subject the shell and its service equipment to an effective internal pressure of not less than 25% of the MAWP. For portable tanks used for refrigerated liquefied gases the leakage test must be conducted at an effective internal pressure of not less than 90% of the MAWP.

Maximum allowable working pressure (MAWP) is defined differently depending on the hazardous materials intended to be transported in the portable tank. See §§ 178.275, 178.276 and 178.277, as applicable.

Maximum permissible gross mass (MPGM) means the sum of the tare mass of the portable tank and the heaviest hazardous material authorized for transportation.

Mild steel means a steel with a guaranteed minimum tensile strength of 360 N/mm² to 440 N/mm² and a guaranteed minimum elongation at fracture as specified in paragraph § 178.274(c)(11).

Offshore portable tank means a portable tank specially designed for repeated use in the transportation of hazardous materials to, from and between offshore facilities. An offshore portable tank is designed and constructed in accordance with the Guidelines for the Approval of Containers Handled in Open Seas specified in the IMDG Code (incorporated by reference, see § 171.7 of this subchapter).

Reference steel means a steel with a tensile strength of 370 N/mm² and an elongation at fracture of 27%.

Service equipment means measuring instruments and filling, discharge, venting, safety, heating, cooling and insulating devices.

Shell means the part of the portable tank which retains the hazardous materials intended for transportation, including openings and their closures, but does not include service equipment or external structural equipment.

Structural equipment means the reinforcing, fastening, protective and stabilizing members external to the shell.

Test pressure means the maximum gauge pressure at the top of the shell during the hydraulic pressure test equal to not less than 1.5 times the design pressure for liquids and 1.3 for liquefied compressed gases. The minimum test pressure for portable tanks intended for specific hazardous materials is specified in the applicable portable tank T code assigned to a particular hazardous material in the § 172.101 Table of this subchapter.

(b) General design and construction requirements. (1) The design temperature range for the shell must be −40 °C to 50 °C (−40 °F to 122 °F) for hazardous materials transported under normal conditions of transportation, except for portable tanks used for refrigerated liquefied gases where the minimum design temperature must not be higher than the lowest (coldest) temperature (for example, service temperature) of the contents during filling, discharge or transportation. For hazardous materials handled under elevated temperature conditions, the design temperature must not be less than the maximum temperature of the hazardous material during filling, discharge or transportation. More severe design temperatures must be considered for portable tanks subjected to severe climatic conditions (for example, portable tanks transported in arctic regions). Shells must be designed and constructed in accordance with the requirements of the ASME Code, Section VIII, Division 1 (incorporated by reference, see § 171.7 of this subchapter), except as limited or modified in this subchapter. For portable tanks used for liquid or solid hazardous materials, a design code other than the ASME Code may be used if approved by the Associate Administrator. Portable tanks used for liquified compressed gases require an ASME certification and U stamp. Shells must be made of metallic materials suitable for forming. Non-metallic materials may be used for the attachments and supports between the shell and jacket, provided their material properties at the minimum and maximum design temperatures are proven to be sufficient. For welded shells, only a material whose weldability has been fully demonstrated may be used. Welds must be of high quality and conform to a level of integrity at least equivalent to the welding requirements specified in the ASME Code, Section VIII for the welding of pressure vessels. When the manufacturing process or the materials make it necessary, the shells must be suitably heat-treated to guarantee adequate toughness in the weld and in the heat affected zones. In choosing the material, the design temperature range must be taken into account with respect to risk of brittle fracture, stress corrosion cracking, resistance to impact, and suitability for the hazardous materials intended for transportation in the portable tank. When fine grain steel is used, the guaranteed value of the yield strength must be not more than 460 N/mm² and the guaranteed value of the upper limit of the tensile strength must be not more than 725 N/mm² according to the material specification. Aluminum may not be used as a construction material for the shell. Portable tank materials must be suitable for the external environment where they will be transported taking into account the determined design temperature range. Portable tanks must be designed to withstand, without loss of contents, at least the internal pressure due to the contents and the static, dynamic and thermal loads during normal conditions of handling and transportation. The design must take into account the effects of fatigue, caused by repeated application of these loads through the expected life of the portable tank.

(2) Portable tank shells, fittings, and pipework must be constructed from materials that are:

(i) Compatible with the hazardous materials intended to be transported; or

(ii) Properly passivated or neutralized by chemical reaction, if applicable; or

(iii) For portable tanks used for liquid and solid materials, lined with corrosion-resistant material directly bonded to the shell or attached by equivalent means.

(3) Gaskets and seals must be made of materials that are compatible with the hazardous materials intended to be transported.

(4) When shells are lined, the lining must be compatible with the hazardous materials intended to be transported, homogeneous, non-porous, free from perforations, sufficiently elastic and compatible with the thermal expansion characteristics of the shell. The lining of every shell, shell fittings and piping must be continuous and must extend around the face of any flange. Where external fittings are welded to the tank, the lining must be continuous through the fitting and around the face of external flanges. Joints and seams in the lining must be made by fusing the material together or by other equally effective means.

(5) Contact between dissimilar metals which could result in damage by galvanic action must be prevented by appropriate measures.

(6) The construction materials of the portable tank, including any devices, gaskets, linings and accessories, must not adversely affect or react with the hazardous materials intended to be transported in the portable tank.

(7) Portable tanks must be designed and constructed with supports that provide a secure base during transportation and with suitable lifting and tie-down attachments.

(c) Design criteria. (1) Portable tanks and their fastenings must, under the maximum permissible load, be capable of absorbing the following separately applied static forces (for calculation purposes, acceleration due to gravity (g) = 9.81m/s²):

(i) In the direction of travel: 2g (twice the MPGM multiplied by the acceleration due to gravity);

(ii) Horizontally at right angles to the direction of travel: 1g (the MPGM multiplied by the acceleration due to gravity);

(iii) Vertically upwards: 1g (the MPGM multiplied by the acceleration due to gravity); and

(iv) Vertically downwards: 2g (twice the MPGM multiplied by the acceleration due to gravity).

(2) Under each of the forces specified in paragraph (c)(1) of this section, the safety factor must be as follows:

(i) For metals having a clearly defined yield point, a design margin of 1.5 in relation to the guaranteed yield strength; or

(ii) For metals with no clearly defined yield point, a design margin of 1.5 in relation to the guaranteed 0.2% proof strength and, for austenitic steels, the 1% proof strength.

(3) The values of yield strength or proof strength must be the values according to recognized material standards. When austenitic steels are used, the specified minimum values of yield strength or proof strength according to the material standards may be increased by up to 15% when these greater values are attested in the material inspection certificate.

(4) Portable tanks must be capable of being electrically grounded to prevent dangerous electrostatic discharge when they are used for Class 2 flammable gases or Class 3 flammable liquids, including elevated temperature materials transported at or above their flash point.

(5) For shells of portable tanks used for liquefied compressed gases, the shell must consist of a circular cross section. Shells must be of a design capable of being stress-analysed mathematically or experimentally by resistance strain gauges as specified in UG-101 of the ASME Code (incorporated by reference, see § 171.7 of this subchapter), or other methods approved by the Associate Administrator.

(6) Shells must be designed and constructed to withstand a hydraulic test pressure of not less than 1.5 times the design pressure for portable tanks used for liquids and 1.3 times the design pressure for portable tanks used for liquefied compressed gases. Specific requirements are provided for each hazardous material in the applicable T Code or portable tank special provision specified in the § 172.101 Table of this subchapter. The minimum shell thickness requirements must also be taken into account.

(7) For metals exhibiting a clearly defined yield point or characterized by a guaranteed proof strength (0.2% proof strength, generally, or 1% proof strength for austenitic steels), the primary membrane stress (sigma) in the shell must not exceed 0.75 Re or 0.50 Rm, whichever is lower, at the test pressure, where:

Re = yield strength in N/mm², or 0.2% proof strength or, for austenitic steels, 1% proof strength;

Rm = minimum tensile strength in N/mm².

(8) The values of Re and Rm to be used must be the specified minimum values according to recognized material standards. When austenitic steels are used, the specified minimum values for Re and Rm according to the material standards may be increased by up to 15% when greater values are attested in the material inspection certificate.

(9) Steels which have a Re/Rm ratio of more than 0.85 are not allowed for the construction of welded shells. The values of Re and Rm to be used in determining this ratio must be the values specified in the material inspection certificate.

(10) Steels used in the construction of shells must have an elongation at fracture, in percentage, of not less than 10,000/Rm with an absolute minimum of 16% for fine grain steels and 20% for other steels.

(11) For the purpose of determining actual values for materials for sheet metal, the axis of the tensile test specimen must be at right angles (transversely) to the direction of rolling. The permanent elongation at fracture must be measured on test specimens of rectangular cross sections in accordance with ISO 6892 (see § 171.7 of this subchapter), using a 50 mm gauge length.

(d) Minimum shell thickness. (1) The minimum shell thickness must be the greatest thickness of the following:

(i) the minimum thickness determined in accordance with the requirements of paragraphs (d)(2) through (d)(10) of this section;

(ii) the minimum thickness determined in accordance with the ASME Code (incorporated by reference, see § 171.7 of this subchapter) or other approved pressure vessel code; or

(iii) the minimum thickness specified in the applicable T code or portable tank special provision indicated for each hazardous material in the § 172.101 Table of this subchapter.

(2) Shells (cylindrical portions, heads and manhole covers) not more than 1.80 m in diameter may not be less than 5 mm thick in the reference steel or of equivalent thickness in the metal to be used. Shells more than 1.80 m in diameter may not be less than 6 mm thick in the reference steel or of equivalent thickness in the metal to be used. For portable tanks used only for the transportation of powdered or granular solid hazardous materials of Packing Group II or III, the minimum thickness requirement may be reduced to 5 mm in the reference steel or of equivalent thickness in the metal to be used regardless of the shell diameter. For vacuum-insulated tanks, the aggregate thickness of the jacket and the shell must correspond to the minimum thickness prescribed in this paragraph, with the thickness of the shell itself not less than the minimum thickness prescribed in paragraph (d)(3) of this section.

(3) When additional protection against shell damage is provided in the case of portable tanks used for liquid and solid hazardous materials requiring test pressures less than 2.65 bar (265.0 kPa), subject to certain limitations specified in the UN Recommendations (incorporated by reference, see § 171.7 of this subchapter), the Associate Administrator may approve a reduced minimum shell thickness.

(4) The cylindrical portions, heads and manhole covers of all shells must not be less than 3 mm (0.1 inch) thick regardless of the material of construction, except for portable tanks used for liquefied compressed gases where the cylindrical portions, ends (heads) and manhole covers of all shells must not be less than 4 mm (0.2 inch) thick regardless of the material of construction.

(5) When steel that has characteristics other than that of reference steel is used, the equivalent thickness of the shell and heads must be determined according to the following formula:

Where:

e₁ = required equivalent thickness (in mm) of the metal to be used;

e₀ = minimum thickness (in mm) of the reference steel specified in the applicable T code or portable tank special provision indicated for each material in the § 172.101 Table of this subchapter;

d₁ = 1.8m, unless the formula is used to determine the equivalent minimum thickness for a portable tank shell that is required to have a minimum thickness of 8mm or 10mm according to the applicable T code indicated in the § 172.101 Table of this subchapter. When reference steel thicknesses of 8mm or 10mm are specified, d₁ is equal to the actual diameter of the shell but not less than 1.8m;

Rm₁ = guaranteed minimum tensile strength (in N/mm²) of the metal to be used;

A₁ = guaranteed minimum elongation at fracture (in %) of the metal to be used according to recognized material standards.

(6) The wall and all parts of the shell may not have a thickness less than that prescribed in paragraphs (d)(2), (d)(3) and (d)(4) of this section. This thickness must be exclusive of any corrosion allowance.

(7) There must be no sudden change of plate thickness at the attachment of the heads to the cylindrical portion of the shell.

(e) Service equipment. (1) Service equipment must be arranged so that it is protected against the risk of mechanical damage by external forces during handling and transportation. When the connections between the frame and the shell allow relative movement between the sub-assemblies, the equipment must be fastened to allow such movement without risk of damage to working parts. The external discharge fittings (pipe sockets, shut-off devices) and the internal stop-valve and its seating must be protected against mechanical damage by external forces (for example, by using shear sections). The filling and discharge devices (including flanges or threaded plugs) and any protective caps must be capable of being secured against unintended opening.

(2) Each connection to a portable tank must be clearly marked to indicate its function.

(3) Each stop-valve or other means of closure must be designed and constructed to a rated pressure not less than the MAWP of the shell taking into account the temperatures expected during transport. All stop-valves with screwed spindles must close by a clockwise motion of the handwheel. For other stop-valves the position (open and closed) and direction of closure must be clearly indicated. All stop-valves must be designed to prevent unintentional opening.

(4) Piping must be designed, constructed and installed to avoid the risk of damage due to thermal expansion and contraction, mechanical shock and vibration. All piping must be of a suitable metallic material. Welded pipe joints must be used wherever possible.

(5) Joints in copper tubing must be brazed or have an equally strong metal union. The melting point of brazing materials must be no lower than 525 °C (977 °F). The joints must not decrease the strength of the tubing, such as may happen when cutting threads.

(6) The burst pressure of all piping and pipe fittings must be greater than the highest of four times the MAWP of the shell or four times the pressure to which it may be subjected in service by the action of a pump or other device (except pressure relief devices).

(7) External fittings must be grouped together. Filling and discharge connections may be installed below the normal liquid level of the tank if the tank design conforms to the following requirements:

(i) The portable tank must be permanently mounted in a full framework for containerized transport. For each portable tank design, a prototype portable tank, must fulfill the requirements of parts 450 through 453 of this title for compliance with the requirements of Annex II of the International Convention for Safe Containers.

(ii) Each filling and discharge connection must be equipped with an internal self-closing stop-valve capable of closing within 30 seconds of actuation. Each internal self-closing stop-valve must be protected by a shear section or sacrificial device located outboard of the valve. The shear section or sacrificial device must break at no more than 70 percent of the load that would cause failure of the internal self-closing stop-valve.

(iii) Each internal self-closing stop-valve must be provided with remote means of automatic closure, both thermal and mechanical. The thermal means of automatic closure must actuate at a temperature of not over 121 °C (250 °F).

(8) Ductile metals must be used in the construction of valves and accessories.

(f) Pressure relief devices.—(1) Marking of pressure relief devices. Every pressure relief device must be clearly and permanently marked with the following:

(i) the pressure (in bar or kPa) or temperature for fusible elements (in °C) at which it is set to discharge;

(ii) the allowable tolerance at the discharge pressure for reclosing devices;

(iii) the reference temperature corresponding to the rated pressure for frangible discs;

(iv) the allowable temperature tolerance for fusible elements;

(v) the rated flow capacity of the device in standard cubic meters of air per second (m³/s) determined according to ISO 4126-1 (incorporated by reference, see § 171.7 of this subchapter); and

(vi) when practicable, the device must show the manufacturer's name and product number.

(2) Connections to pressure relief devices. Connections to pressure relief devices must be of sufficient size to enable the required discharge to pass unrestricted to the safety device. No stop-valve may be installed between the shell and the pressure relief devices except where duplicate devices are provided for maintenance or other reasons and the stop-valves serving the devices actually in use are locked open or the stop-valves are interlocked so that at least one of the duplicate devices is always in use. There must be no obstruction in an opening leading to a vent or pressure relief device which might restrict or cut-off the flow from the shell to that device. Vents or pipes from the pressure relief device outlets, when used, must deliver the relieved vapor or liquid to the atmosphere in conditions of minimum back-pressure on the relieving devices.

(3) Location of pressure relief devices. (i) Each pressure relief device inlet must be situated on top of the shell in a position as near the longitudinal and transverse center of the shell as reasonably practicable. All pressure relief device inlets must, under maximum filling conditions, be situated in the vapor space of the shell and the devices must be so arranged as to ensure that escaping vapor is discharged unrestrictedly. For flammable hazardous materials, the escaping vapor must be directed away from the shell in such a manner that it cannot impinge upon the shell. For refrigerated liquefied gases, the escaping vapor must be directed away from the tank and in such a manner that it cannot impinge upon the tank. Protective devices which deflect the flow of vapor are permissible provided the required relief-device capacity is not reduced.

(ii) Arrangements must be made to prevent unauthorized persons from access to the pressure relief devices and to protect the devices from damage caused by the portable tank overturning.

(g) Gauging devices. Unless a portable tank is intended to be filled by weight, it must be equipped with one or more gauging devices. Glass level-gauges and gauges made of other fragile material, which are in direct communication with the contents of the tank are prohibited. A connection for a vacuum gauge must be provided in the jacket of a vacuum-insulated portable tank.

(h) Portable tank supports, frameworks, lifting and tie-down attachments. (1) Portable tanks must be designed and constructed with a support structure to provide a secure base during transport. The forces and safety factors specified in paragraphs (c)(1) and (c)(2) of this section, respectively, must be taken into account in this aspect of the design. Skids, frameworks, cradles or other similar structures are acceptable.

(2) The combined stresses caused by portable tank mountings (for example, cradles, framework, etc.) and portable tank lifting and tie-down attachments must not cause excessive stress in any portion of the shell. Permanent lifting and tie-down attachments must be fitted to all portable tanks. Preferably they should be fitted to the portable tank supports but may be secured to reinforcing plates located on the shell at the points of support. Each portable tank must be designed so that the center of gravity of the filled tank is approximately centered within the points of attachment for lifting devices.

(3) In the design of supports and frameworks, the effects of environmental corrosion must be taken into account.

(4) Forklift pockets must be capable of being closed off. The means of closing forklift pockets must be a permanent part of the framework or permanently attached to the framework. Single compartment portable tanks with a length less than 3.65 m need not have forklift pockets that are capable of being closed off provided that:

(i) The shell, including all the fittings, are well protected from being hit by the forklift blades; and

(ii) The distance between forklift pockets (measured from the center of each pocket) is at least half of the maximum length of the portable tank.

(5) During transport, portable tanks must be adequately protected against damage to the shell, and service equipment resulting from lateral and longitudinal impact and overturning on the shell and service equipment must be constructed to withstand impact or overturning. External fittings must be protected so as to preclude the release of the shell contents upon impact or overturning of the portable tank on its fittings. Examples of protection include:

(i) Protection against lateral impact which may consist of longitudinal bars protecting the shell on both sides at the level of the median line;

(ii) Protection of the portable tank against overturning which may consist of reinforcement rings or bars fixed across the frame;

(iii) Protection against rear impact which may consist of a bumper or frame;

(iv) Protection of the shell against damage from impact or overturning by use of an ISO frame in accordance with ISO 1496-3 (incorporated by reference, see § 171.7 of this subchapter); and

(v) Protection of the portable tank from impact or overturning by a vacuum insulation jacket.

(i) Marking. (1) Every portable tank must be fitted with a corrosion resistant metal plate permanently attached to the portable tank in a conspicuous place and readily accessible for inspection. When the plate cannot be permanently attached to the shell, the shell must be marked with at least the information required by the ASME Code (incorporated by reference, see § 171.7 of this subchapter). At a minimum, the following information must be marked on the plate by stamping or by any other similar method:

62. Section 178.275 would be added to subpart H to read as follows:

§ 178.275

Specification for UN Portable Tanks intended for the transportation of liquid and solid hazardous materials.

(a) In addition to the requirements of § 178.274, the following definitions and requirements apply to UN portable tanks intended for the transportation of liquid and solid hazardous materials:

(1) Design pressure means the pressure to be used in calculations required by the recognized pressure vessel code. The design pressure must not be less than the highest of the following pressures:

(i) The maximum effective gauge pressure allowed in the shell during filling or discharge; or

(ii) The sum of:

(A) The absolute vapor pressure (in bar) of the hazardous material at 65 °C, minus 1 bar (149 °F, minus 100 kPa);

(B) The partial pressure (in bar) of air or other gases in the ullage space, resulting from their compression during filling without pressure relief by a maximum ullage temperature of 65 °C (149 °F) and a liquid expansion due to an increase in mean bulk temperature of 35 °C (95 °F); and

(C) A head pressure determined on the basis of the forces specified in § 178.274(c), but not less than 0.35 bar (35 kPa).

(2) Maximum allowable working pressure (MAWP) means a pressure that must not be less than the highest of the following pressures measured at the top of the shell while in operating position:

(ii) The maximum effective gauge pressure to which the shell is designed which must be not less than the design pressure.

(b) Service equipment. (1) In addition to the requirements specified in § 178.274, for service equipment, all openings in the shell, intended for filling or discharging the portable tank must be fitted with a manually operated stop-valve located as close to the shell as reasonably practicable. Other openings, except for openings leading to venting or pressure relief devices, must be equipped with either a stop-valve or another suitable means of closure located as close to the shell as reasonably practicable.

(2) All portable tanks must be fitted with a manhole or other inspection openings of a suitable size to allow for internal inspection and adequate access for maintenance and repair of the interior. Compartmented portable tanks must have a manhole or other inspection openings for each compartment.

(3) For insulated portable tanks, top fittings must be surrounded by a spill collection reservoir with suitable drains.

(4) Piping must be designed, constructed and installed to avoid the risk of damage due to thermal expansion and contraction, mechanical shock and vibration. All piping must be of a suitable metallic material. Welded pipe joints must be used wherever possible.

(c) Bottom openings. (1) Certain hazardous materials may not be transported in portable tanks with bottom openings. When the applicable T code or portable tank special provision, as referenced for materials in the § 172.101 Table of this subchapter, specifies that bottom openings are prohibited, there must be no openings below the liquid level of the shell when it is filled to its maximum permissible filling limit. When an existing opening is closed, it must be accomplished by internally and externally welding one plate to the shell.

(2) Bottom discharge outlets for portable tanks carrying certain solid, crystallizable or highly viscous hazardous materials must be equipped with at least two serially fitted and mutually independent shut-off devices. Use of only two shut-off devices is only authorized when this paragraph is referenced in the applicable T Code indicated for each hazardous material in the § 172.101 Table of this subchapter. The design of the equipment must be to the satisfaction of the approval agency and must include:

(i) An external stop-valve fitted as close to the shell as reasonably practicable; and

(ii) A liquid tight closure at the end of the discharge pipe, which may be a bolted blank flange or a screw cap.

(3) Except as provided in paragraph (c)(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 be to the satisfaction of the approval agency and must include:

(i) A self-closing internal stop-valve, which is a stop-valve within the shell or within a welded flange or its companion flange, such that:

(A) The control devices for the operation of the valve are designed to prevent any unintended opening through impact or other inadvertent act;

(B) The valve is operable from above or below;

(C) If possible, the setting of the valve (open or closed) must be capable of being verified from the ground;

(D) Except for portable tanks having a capacity less than 1,000 liters (264.2 gallons), it must be possible to close the valve from an accessible position of the portable tank that is remote from the valve itself; and

(E) The valve must continue to be effective in the event of damage to the external device for controlling the operation of the valve;

(ii) An external stop-valve fitted as close to the shell as reasonably practicable; and

(iii) A liquid tight closure at the end of the discharge pipe, which may be a bolted blank flange or a screw cap.

(4) For a lined shell, the internal stop-valve required by paragraph (c)(3)(i) of this section may be replaced by an additional external stop-valve.

(d) Pressure relief devices. All portable tanks must be fitted with at least one pressure relief device. All relief devices must be designed, constructed and marked in accordance with the requirements of this subchapter.

(e) Vacuum-relief devices. (1) A shell which is to be equipped with a vacuum-relief device must be designed to withstand, without permanent deformation, an external pressure of not less than 0.21 bar (21.0 kPa) above the internal pressure. The vacuum-relief device must be set to relieve at a vacuum setting not greater than minus (−) 0.21 bar (−21.0 kPa) unless the shell is designed for a higher external over pressure, in which case the vacuum-relief pressure of the device to be fitted must not be greater than the tank design vacuum pressure. A shell that is not fitted with a vacuum-relief device must be designed to withstand, without permanent deformation, an external pressure of not less than 0.4 bar (40.0 kPa) above the internal pressure.

(2) Vacuum-relief devices used on portable tanks intended for the transportation of hazardous materials meeting the criteria of Class 3, including elevated temperature hazardous materials transported at or above their flash point, must prevent the immediate passage of flame into the shell or the portable tank must have a shell capable of withstanding, without leakage, an internal explosion resulting from the passage of flame into the shell.

(f) Pressure relief devices. (1) Each portable tank with a capacity not less than 1,900 liters (501.9 gallons) and every independent compartment of a portable tank with a similar capacity, must be provided with one or more pressure relief devices of the reclosing type. Such portable tanks may, in addition, have a frangible disc or fusible element in parallel with the reclosing devices, except when the applicable T code assigned to a hazardous material requires that the frangible disc precede the pressure relief device, according to paragraph (f)(3) of this section, or when no bottom openings are allowed. The pressure relief devices must have sufficient capacity to prevent rupture of the shell due to over pressurization or vacuum resulting from filling, discharging, from heating of the contents or fire.

(2) Pressure relief devices must be designed to prevent the entry of foreign matter, the leakage of liquid and the development of any dangerous excess pressure.

(3) When required for certain hazardous materials by the applicable T code or portable tank special provision specified for a hazardous material in the § 172.101 Table of this subchapter, portable tanks must have a pressure relief device consistent with the requirements of this subchapter. Except for a portable tank in dedicated service that is fitted with an approved relief device constructed of materials compatible with the hazardous material, the relief device system must include a frangible disc preceding a reclosing pressure relief device. A pressure gauge or suitable tell-tale indicator for the detection of disc rupture, pin-holing or leakage must provide the space between the frangible disc and the pressure relief device. The frangible disc must rupture at a nominal pressure 10% above the start to discharge pressure of the relief device.

(4) Every portable tank with a capacity less than 1,900 liters (501.9 gallons) must be fitted with a pressure relief device, which may be a frangible disc when this disc is set to rupture at a nominal pressure equal to the test pressure at any temperature within the design temperature range.

(5) When the shell is fitted for pressure discharge, a suitable pressure relief device must provide the inlet line to the portable tank set to operate at a pressure not higher than the MAWP of the shell, and a stop-valve must be fitted as close to the shell to minimize the potential for damage.

(6) Setting of pressure relief devices. (i) Pressure relief devices must operate only in conditions of excessive rise in temperature, since the shell must not be subject to undue fluctuations of pressure during normal conditions of transportation.

(ii) The required pressure relief device must be set to start-to-discharge at a nominal pressure of five-sixths of the test pressure for shells having a test pressure of not more than 4.5 bar (450 kPa) and 110% of two-thirds of the test pressure for shells having a test pressure of more than 4.5 bar (450 kPa). A self-closing relief device must close at a pressure not more than 10% below the pressure at which the discharge starts. The device must remain closed at all lower pressures. This requirement does not prevent the use of vacuum-relief or combination pressure relief and vacuum-relief devices.

(g) Fusible elements. Fusible elements must operate at a temperature between 110 °C (230 °F) and 149 °C (300.2 °F) provided that the pressure in the shell at the fusing temperature will not exceed the test pressure. They must be placed at the top of the shell with their inlets in the vapor space and in no case may they be shielded from external heat. Fusible elements must not be utilized on portable tanks with a test pressure which exceeds 2.65 bar (265.0 kPa). Fusible elements used on portable tanks intended for the transport of elevated temperature hazardous materials must be designed to operate at a temperature higher than the maximum temperature that will be experienced during transport and must be to the satisfaction of the approval agency.

(h) Capacity of pressure relief devices. (1) The reclosing pressure relief device required by paragraph (f)(1) must have a minimum cross sectional flow area equivalent to an orifice of 31.75 mm (1.3 inches) diameter. Vacuum-relief devices, when used, must have a cross sectional flow area not less than 284 mm² (11.2 inches²).

(2) Under conditions of complete fire engulfment of the portable tank, the combined delivery capacity of the relief devices must be sufficient to limit the pressure in the shell to 20% above the start-to-discharge pressure specified in paragraph(f)(6) of this section. Emergency pressure relief devices may be used to achieve the full relief capacity prescribed. The total required capacity of the relief devices may be determined using the formula in paragraph (h)(2)(i) of this section or the table in paragraph (h)(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 standard 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⁻²·K⁻¹, at 38 °C; and t = actual temperature of the hazardous material during filling (in °C) or when this temperature is unknown, let t = 15 °C. The value of F given above for insulated shells may only be used if the insulation is in conformance with paragraph (h)(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 (h)(2)(i)(A) of this section, is derived from one of the following formula 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:

C Constant Value Table

(ii) As an alternative to the formula in paragraph (h)(2)(i) of this section, relief devices for shells used for transporting liquids may be sized in accordance with the table in paragraph (h)(2)(iii) of this section. The table in paragraph (h)(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 (h)(2)(iii) of this section are: L = 334.94 kJ/kg; M = 86.7; T = 394 K; Z = 1; and C = 0.607.

(iii) Minimum emergency vent capacity, Q, in cubic meters per air per second at 1 bar and 0 °C (273 K), as shown in the following table:

63. Section 178.276 would be added to subpart H to read as follows:

§ 178.276

Requirements for the design, construction, inspection and testing of portable tanks intended for the transportation of liquefied compressed gases.

(a) In addition to the requirements of § 178.274 applicable to UN portable tanks, the following requirements apply to UN portable tanks used for liquefied compressed gases. In addition to the definitions in § 178.274, the following definitions apply:

Design pressure means the pressure to be used in calculations required by the ASME Code (incorporated by reference, see § 171.7 of this subchapter). The design pressure must be not less than the highest of the following pressures:

(i) The maximum effective gauge pressure allowed in the shell during filling or discharge; or

Note to Paragraph (a)(1):

For the purpose of this section, the term “design pressure” as used in this specification is identical to the term “maximum allowable working pressure” as used in the ASME Code, Section VIII.

(2) Design reference temperature means the temperature at which the vapor pressure of the contents is determined for the purpose of calculating the MAWP. The value for each portable tank type is as follows:

(i) Shell with a diameter of 1.5 meters or less: 65 °C; or

(A) Without insulation or sun shield: 60 °C;

(B) With sun shield: 55 °C; and

(C) With insulation: 50 °C.

(3) Filling density means the average mass of liquefied compressed gas per liter of shell capacity (kg/l).

(4) Maximum allowable working pressure (MAWP) means a pressure that must be not less than the highest of the following pressures measured at the top of the shell while in operating position, but in no case less than 7 bar (700 kPa):

(i) The maximum effective gauge pressure allowed in the shell during filling or discharge; or

(ii) The maximum effective gauge pressure to which the shell is designed, which must be:

(A) Not less than the pressure specified for each liquefied compressed gas listed in portable tank special provision T50; and

(B) Not less than the sum of:

(1) The absolute vapor pressure (in bar) of the liquefied compressed gas at the design reference temperature minus 1 bar; and

(2) The partial pressure (in bar) of air or other gases in the ullage space which is determined by the design reference temperature and the liquid phase expansion due to the increase of the mean bulk temperature of t_r-t_f (t_f = filling temperature, usually 15 °C, t_r = 50 °C maximum mean bulk temperature);

(b) General design and construction requirements. (1) Tanks must be of seamless or welded steel construction, or combination of both, and have a water capacity greater than 450 liters (118.9 gallons). Tanks must be designed, constructed, certified and stamped in accordance with the ASME Code, Section VIII (incorporated by reference, see § 171.7 of this subchapter).

(2) Portable tanks must be postweld heat-treated and radiographed as prescribed in the ASME Code, except that each portable tank constructed in accordance with part UHT of the ASME Code must be postweld heat-treated. Where postweld heat treatment is required, the portable tank must be treated as a unit after completion of all the welds in and/or to the shell and heads. The method must be as prescribed in the ASME Code. Welded attachments to pads may be made after postweld heat treatment is made. A portable tank used for anhydrous ammonia must be postweld heat-treated. The postweld heat treatment must be as prescribed in the ASME Code, but in no event at less than 1050 °F tank metal temperature. Additionally, portable tanks constructed in accordance with part UHT of the ASME Code must conform to the following requirements:

In addition to the essential variables named therein, the following must be considered to be essential variables: number of passes, thickness of plate, heat input per pass, and manufacturer's identification of rod and flux. The number of passes, thickness of plate and heat input per pass may not vary more than 25 percent from the procedure qualification. Records of the qualification must be retained for at least 5 years by the tank manufacturer and made available to duly identified representatives of the Department of Transportation or the owner of the tank.

(ii) Impact tests must be made on a lot basis. A lot is defined as 100 tons or less of the same heat and having a thickness variation no greater than plus or minus 25 percent. The minimum impact required for full-sized specimens shall be 20 foot-pounds (or 10 foot-pounds for half-sized specimens) at 0° F Charpy V-Notch in both the longitudinal and transverse direction. If the lot test does not pass this requirement, individual plates may be accepted if they individually meet this impact requirement.

(3) Welding procedures and welder performance tests must be made annually in accordance with Section IX of the ASME Code. In addition to the essential variables named therein, the following must be considered to be essential variables: number of passes, thickness of plate, heat input per pass, and manufacturer's identification of rod and flux. The number of passes, thickness of plate and heat input per pass may not vary more than 25% from the procedure qualification. Records of the qualification must be retained for at least 5 years by the portable tank manufacturer and made available to the approval agency and the owner of the tank as specified in § 178.273.

(4) Impact tests must be made on a lot basis. A lot is defined as 100 tons or less of raw material of the same heat and having a thickness variation no greater than plus or minus 25%. The minimum impact required for full-sized specimens must be 20 foot-pounds (or 10 foot-pounds for half-sized specimens) at 0° F Charpy V-Notch in both the longitudinal and transverse direction. If the lot test does not pass this requirement, individual plates may be accepted if they individually meet this impact requirement.

(5) When the shells intended for the transportation of liquefied compressed gases are equipped with thermal insulation, a device must be provided to prevent any dangerous pressure from developing in the insulating layer in the event of a leak, when the protective covering is so closed as to be gas-tight. The thermal insulation must not inhibit access to the fittings and discharge devices. In addition, the thermal insulation systems must satisfy the following requirements:

(i) Consist of a shield covering not less than the upper third, but not more than the upper half of the surface of the shell, and separated from the shell by an air space of approximately 40 mm across; or

(ii) Consist of a complete cladding of insulating materials. The insulation must be of adequate thickness and constructed to prevent the ingress of moisture and damage to the insulation. The insulation and cladding must have a thermal conductance of not more than 0.67 (W·m⁻²·K⁻¹) under normal conditions of transportation.

(c) Service equipment. (1) All openings with a diameter of more than 1.5 mm (.1 inch) in shells of portable tanks, except openings for pressure-relief devices, inspection openings and closed bleed holes, must be fitted with at least three mutually independent shut-off devices in series: the first being an internal stop-valve, excess flow valve, integral excess flow valve, or excess flow feature device (see § 178.337-1(g)), the second being an external stop-valve and the third being a blank flange or equivalent device.

(2) When a portable tank is fitted with an excess flow valve, the excess flow valve must be so fitted that its seating is inside the shell or inside a welded flange or, when fitted externally, its mountings must be designed so that in the event of impact it must maintain its effectiveness. The excess flow valves must be selected and fitted so as to close automatically when the rated flow specified by the manufacturer is reached. Connections and accessories leading to or from such a valve must have a capacity for a flow more than the excess flow valve's rated flow.

(3) For filling and discharge openings, the first shut-off device must be an internal stop-valve and the second must be a stop-valve placed in an accessible position on each discharge and filling pipe.

(4) For filling and discharge bottom openings of portable tanks intended for the transportation of flammable and/or toxic liquefied compressed gases, the internal stop-valve must be a quick closing safety device that closes automatically in the event of unintended movement of the portable tank during filling or discharge or fire engulfment. Except for portable tanks having a capacity of not more than 1,000 liters (264.2 gallons), it must be possible to operate this device by remote control.

(5) In addition to filling, discharge and gas pressure equalizing orifices, shells may have openings in which gauges, thermometers and manometers can be fitted. Connections for such instruments must be made by suitable welded nozzles or pockets and may not be connected by screwed connections through the shell.

(6) All portable tanks must be fitted with manholes or other inspection openings of suitable size to allow for internal inspection and adequate access for maintenance and repair of the interior.

(d) Bottom openings. Bottom openings are prohibited on portable tanks when the portable tank special provision T50 in § 172.102(c)(7) of this subchapter indicates that bottom openings are not allowed. In this case, there may be no openings located below the liquid level of the shell when it is filled to its maximum permissible filling limit.

(e) Pressure relief devices. (1) Portable tanks must be provided with one or more reclosing pressure relief devices. The pressure relief devices must open automatically at a pressure not less than the MAWP and be fully open at a pressure equal to 110% of the MAWP. These devices must, after discharge, close at a pressure not less than 10% below the pressure at which discharge starts and must remain closed at all lower pressures. The pressure relief devices must be of a type that will resist dynamic forces including liquid surge. A frangible disc may only be used in series with a reclosing pressure relief device.

(2) Pressure relief devices must be designed to prevent the entry of foreign matter, the leakage of gas and the development of any dangerous excess pressure.

(3) Portable tanks intended for the transportation of certain liquefied compressed gases identified in portable tank special provision T50 in § 172.102 of this subchapter must have a pressure relief device which conforms to the requirements of this subchapter. Unless a portable tank in dedicated service is fitted with a relief device constructed of materials compatible with the hazardous material, the relief device must comprise a frangible disc preceded by a reclosing device. The space between the frangible disc and the device must be provided with a pressure gauge or a suitable tell-tale indicator. This arrangement must facilitate the detection of disc rupture, pinholing or leakage which could cause a malfunction of the pressure relief device. The frangible discs must rupture at a nominal pressure 10% above the start-to-discharge pressure of the relief device.

(4) In the case of portable tanks used for more than one gas, the pressure relief devices must open at a pressure indicated in paragraph (f) of this section for the gas having the highest maximum allowable pressure of the gases allowed to be transported in the portable tank.

(f) Capacity of relief devices. The combined delivery capacity of the relief devices must be sufficient so that, in the event of total fire engulfment, the pressure inside the shell cannot exceed 120% of the MAWP. Reclosing relief devices must be used to achieve the full relief capacity prescribed. In the case of portable tanks used for more than gas, the combined delivery capacity of the pressure relief devices must be taken for the liquefied compressed gas which requires the highest delivery capacity of the liquefied compressed gases allowed to be transported in the portable tank. The total required capacity of the relief devices must be determined according to the requirements in § 178.275(h). These requirements apply only to liquefied compressed gases which have critical temperatures well above the temperature at the accumulating condition. For gases which have critical temperatures near or below the temperature at the accumulating condition, the calculation of the pressure relief device delivery capacity must consider the additional thermodynamic properties of the gas (for example, CGA S-1.2-1995; incorporated by reference, see § 171.7 of this subchapter).

64. A new § 178.277 would be added to subpart H to read as follows:

§ 178.277

Requirements for the design, construction, inspection and testing of portable tanks intended for the transportation of refrigerated liquefied gases.

(a) In addition to the requirements of § 178.274 applicable to UN portable tanks, the following requirements and definitions apply to UN portable tanks used for refrigerated liquefied gases:

(1) Design pressure. For the purpose of this section the term design pressure is consistent with the definition for design pressure in the ASME Code, Section VIII (incorporated by reference, see § 171.7 of this subchapter).

(2) Holding time is the time, as determined by testing, that will elapse from loading until the pressure of the contents, under equilibrium conditions, reaches the lowest set pressure of the pressure limiting device(s) (for example, pressure control valve or pressure relief device). Holding time must be determined as specified in § 178.338-9.

(3) Maximum allowable working pressure (MAWP) means the maximum effective gauge pressure permissible at the top of the shell of a loaded portable tank in its operating position including the highest effective pressure during filling and discharge;

(4) Minimum design temperature means the temperature which is used for the design and construction of the shell not higher than the lowest (coldest) service temperature of the contents during normal conditions of filling, discharge and transportation.

(5) Shell means the part of the portable tank which retains the refrigerated liquefied gas intended for transport, including openings and their closures, but does not include service equipment or external structural equipment.

(6) Tank means a construction which normally consists of either :

(i) A jacket and one or more inner shells where the space between the shell(s) and the jacket is exhausted of air (vacuum insulation) and may incorporate a thermal insulation system; or

(ii) A jacket and an inner shell with an intermediate layer of solid thermally insulating material (for example, solid foam).

(b) General design and construction requirements. (1) Portable tanks must be of seamless or welded steel construction and have a water capacity of more than 450 liters (118.9 gallons). Portable tanks must be designed, constructed, certified and stamped in accordance with the ASME Code (incorporated by reference, see § 171.7 of this subchapter).

(2) Portable tanks must be postweld heat treated and radiographed as prescribed in the ASME Code except that each tank constructed in accordance with part UHT of the ASME Code must be postweld heat treated. Where postweld heat treatment is required, the tank must be treated as a unit after completion of all the welds to the shell and heads. The method must be as prescribed in the ASME Code. Welded attachments to pads may be made after postweld heat treatment is made. The postweld heat treatment must be as prescribed in the ASME Code, but in no event at less than 1050 °F tank metal temperature.

(3) Welding procedure and welder performance tests must be made annually in accordance with Section IX of the ASME Code (incorporated by reference, see § 171.7 of this subchapter). In addition to the essential variables named in the ASME Code, the following must be considered as essential variables: number of passes, thickness of plate, heat input per pass, and the specified rod and flux. The number of passes, thickness of plate and heat input per pass may not vary more than 25% from the procedure qualification. Records of the qualification must be retained for at least 5 years by the portable tank manufacturer and made available to the approval agency and the owner of the portable tank as specified in § 178.273.

(4) Impact tests must be made on a lot basis. A lot is defined as 100 tons or less of the same heat and having a thickness variation no greater than plus or minus 25%. The minimum impact required for full-sized specimens must be 20 foot-pounds (or 10 foot-pounds for half-sized specimens) at 0 °F Charpy V-Notch in both the longitudinal and transverse direction. If the lot test does not pass this requirement, individual plates may be accepted if they individually meet this impact requirement.

(5) Shells and jackets must be made of metallic materials suitable for forming. Jackets must be made of steel. Non-metallic materials may be used for the attachments and supports between the shell and jacket, provided their material properties at the minimum design temperature are proven to be sufficient. In choosing the material, the minimum design temperature must be taken into account with respect to risk of brittle fracture, to hydrogen embrittlement, to stress corrosion cracking and to resistance to impact.

(6) Any part of a portable tank, including fittings, gaskets and pipe-work, which can be expected normally to come into contact with the refrigerated liquefied gas transported must be compatible with that refrigerated liquefied gas.

(7) The thermal insulation system must include a complete covering of the shell with effective insulating materials. External insulation must be protected by a jacket so as to prevent the ingress of moisture and other damage under normal transport conditions.

(8) When a jacket is so closed as to be gas-tight, a device must be provided to prevent any dangerous pressure from developing in the insulation space.

(9) Materials which may react with oxygen or oxygen enriched atmospheres in a dangerous manner may not be used in portable tanks intended for the transport of refrigerated liquefied gases having a boiling point below minus 182 °C at atmospheric pressure in locations with the thermal insulation where there is a risk of contact with oxygen or with oxygen enriched fluid.

(10) Insulating materials must not deteriorate unduly in service.

(11) A reference holding time must be determined for each refrigerated liquefied gas intended for transport in a portable tank. The reference holding time must be determined by testing in accordance with the requirements of § 178.338-9, considering the following factors:

(i) The effectiveness of the insulation system, determined in accordance with paragraph (b)(12) of this section;

(ii) The lowest set pressure of the pressure limiting device;

(iii) The initial filling conditions;

(iv) An assumed ambient temperature of 30 °C (86 °F);

(v) The physical properties of the individual refrigerated liquefied gas intended to be transported.

(12) The effectiveness of the insulation system (heat influx in watts) may be determined by type testing the portable tank in accordance with a procedure specified in § 178.338-9(c) or by using the holding time test in § 178.338-9(b). This test must consist of either:

(i) A constant pressure test (for example, at atmospheric pressure) when the loss of refrigerated liquefied gas is measured over a period of time; or

(ii) A closed system test when the rise in pressure in the shell is measured over a period of time.

(13) When performing the constant pressure test, variations in atmospheric pressure must be taken into account. When performing either test, corrections must be made for any variation of the ambient temperature from the assumed ambient temperature reference value of 30 °C (86 °F).

(14) The jacket of a vacuum-insulated double-wall tank must have either an external design pressure not less than 100 kPa (1 bar) gauge pressure calculated in accordance with the ASME Code or a calculated critical collapsing pressure of not less than 200 kPa (2 bar) gauge pressure. Internal and external reinforcements may be included in calculating the ability of the jacket to resist the external pressure.

Note to paragraph (b):

For the determination of the actual holding time as indicated by paragraphs (b)(11), (12) and (13) of this section, before each journey, refer to § 178.338-9(b).

(c) Design criteria. For shells with vacuum insulation, the test pressure must not be less than 1.3 times the sum of the MAWP and 100 kPa (1 bar). In no case may the test pressure be less than 300 kPa (3 bar) gauge pressure.

(d) Service equipment. (1) Each filling and discharge opening in portable tanks used for the transport of flammable refrigerated liquefied gases must be fitted with at least three mutually independent shut-off devices in series: the first being a stop-valve situated as close as reasonably practicable to the jacket, the second being a stop-valve and the third being a blank flange or equivalent device. The shut-off device closest to the jacket must be a quick closing device, which closes automatically in the event of unintended movement of the portable tank during filling or discharge or fire engulfment. This device must be operable by remote control.

(2) Each filling and discharge opening in portable tanks used for the transport of non-flammable refrigerated liquefied gases must be fitted with at least two mutually independent shut-off devices in series: the first being a stop-valve situated as close as reasonably practicable to the jacket and the second a blank flange or equivalent device.

(3) For sections of piping which can be closed at both ends and where liquid product can be trapped, a method of automatic pressure relief must be provided to prevent excess pressure build-up within the piping.

(4) Each connection on a portable tank must be clearly marked to indicate its function.

(5) When pressure-building units are used, the liquid and vapor connections to that unit must be provided with a valve as close to the jacket as reasonably practicable to prevent the loss of contents in case of damage to the pressure-building unit.

(6) The materials of construction of valves and accessories must have satisfactory properties at the lowest operating temperature of the portable tank.

(e) Pressure relief devices. (1) Every shell must be provided with not less than two independent reclosing pressure relief devices. The pressure relief devices must open automatically at a pressure not less than the MAWP and be fully open at a pressure equal to 110% of the MAWP. These devices must, after discharge, close at a pressure not lower than 10% below the pressure at which discharge starts and must remain closed at all lower pressures. The pressure relief devices must be of the type that will resist dynamic forces including surge.

(2) Except for portable tanks used for oxygen, portable tanks for non-flammable refrigerated liquefied gases (except oxygen) and hydrogen may in addition have frangible discs in parallel with the reclosing devices as specified in paragraphs (e)(4)(ii) and (e)(4)(iii) of this section.

(3) Pressure relief devices must be designed to prevent the entry of foreign matter, the leakage of gas and the development of any dangerous excess pressure.

(4) Capacity and setting of pressure relief devices. (i) In the case of the loss of vacuum in a vacuum-insulated tank or of loss of 20% of the insulation of a tank insulated with solid materials, the combined capacity of all pressure relief devices installed must be sufficient so that the pressure (including accumulation) inside the shell does not exceed 120% of the MAWP.

(ii) For non-flammable refrigerated liquefied gases (except oxygen) and hydrogen, this capacity may be achieved by the use of frangible discs in parallel with the required safety-relief devices. Frangible discs must rupture at nominal pressure equal to the test pressure of the shell.

(iii) Under the circumstances described in paragraphs (e)(4)(i) and (e)(4)(ii) of this section, together with complete fire engulfment, the combined capacity of all pressure relief devices installed must be sufficient to limit the pressure in the shell to the test pressure.

(iv) The required capacity of the relief devices must be calculated in accordance with CGA Pamphlet S-1-1.2 (incorporated by reference, see § 171.7 of this subchapter).

65. In § 178.703, paragraph (a)(1) introductory text would be revised and in paragraph (a)(1)(ii), a new sentence would be added at the end of the paragraph to read as follows:

§ 178.703

PART 180—CONTINUING QUALIFICATION AND MAINTENANCE OF PACKAGINGS

69. The authority citation for part 180 would continue to read as follows:

Authority: 49 U.S.C. 5101-5127; 49 CFR 1.53.

70. Subpart G would be added to part 180 to read as follows:

Subpart G—Qualification and Maintenance of Portable Tanks

180.601 180.603 180.605

Subpart G—Qualification and Maintenance of Portable Tanks

§ 180.601

Applicability.

This subpart prescribes requirements, in addition to those contained in parts 107, 171, 172, 173, and 178 of this subchapter, applicable to any person responsible for the continuing qualification, maintenance or periodic retesting of a portable tank.

§ 180.603

Qualification of portable tanks.

(a) Each portable tank used for the transportation of hazardous materials must be an authorized packaging.

(b) To qualify as an authorized packaging, each portable tank must conform to the requirements of this subchapter or the applicable specification to which the portable tank was constructed.

(c) The following portable tanks are authorized for use provided they conform to all applicable safety requirements of this subchapter: 51, 56, 57, 60, IM 101, IM 102 and UN portable tanks.

(d) A portable tank that also meets the definition of “container” in 49 CFR 450.3(a)(3) must conform to the requirements in parts 450 through 453 of this tile for compliance with Annex II of the Convention for Safe Containers (CSC).

(e) Exemption portable tanks based on DOT 51 portable tanks. The owner of a portable tank constructed in accordance with and used under an exemption issued prior to August 31, 1996, which was in conformance with the requirements for Specification DOT 51 portable tanks with the exception of the location of fill and discharge outlets, shall examine the portable tank and its design to determine if it meets the outlet requirements in effect on October 1, 1999. If the owner determines that the portable tank is in compliance with all requirements of the DOT 51 specification, the exemption number stenciled on the portable tank shall be removed and the specification plate (or a plate placed adjacent to the specification plate) shall be durably marked “DOT 51-E*****” (where ***** is to be replaced by the exemption number). During the period the portable tank is in service, and for one year thereafter, the owner of the portable tank must retain on file at its principal place of business a copy of the last exemption in effect.

§ 180.605

Requirements for retest, inspection or repair of portable tanks.

(a) A portable tank constructed in accordance with a DOT specification for which a test or inspection specified in this section has become due, may not be filled and offered for transportation or transported until the test or inspection has been successfully completed. This paragraph (a) does not apply to any portable tank filled prior to the test or inspection due date.

(b) Conditions requiring test and inspection of portable tanks. Without regard to any other test or inspection requirements, a Specification or UN portable tank must be tested and inspected in accordance with this section prior to further use if any of the following conditions exist:

(1) The portable tank shows evidence of bad dents, corroded or abraded areas, leakage, or any other condition that might render it unsafe for transportation service.

(2) The portable tank has been in an accident and has been damaged to an extent that may adversely affect its ability to retain the hazardous material.

(3) The portable tank has been out of hazardous materials transportation service for a period of one year or more.

(4) The portable tank has been modified from its original design specification.

(5) The Department so requires based on the existence of probable cause that the portable tank is in an unsafe operating condition.

(c) Schedule for initial and periodic inspections and tests. Each Specification portable tank must be tested and inspected in accordance with the following schedule:

(1) Each IM or UN portable tank must be given an initial inspection and test before being placed into service, a periodic inspection and test at least once every five years, and an intermediate periodic inspection and test at least every 2.5 years following the last five-year periodic inspection and test.

(2) Each Specification 51 portable tank must be given a periodic inspection and test at least once every five years.

(3) Each Specification 56 or 57 portable tank must be given a periodic inspection and test at least once every 2.5 years.

(4) Each Specification 60 portable tank must be given a periodic inspection and test at the end of the first 4-year period after the original test; at least once every 2 years thereafter up to a total of 12 years of service; and at least once annually thereafter. Retesting is not required on a rubber-lined tank except before each relining.

(d) Initial inspection and test. The initial inspection and test of a portable tank must include the following:

(1) A check of the design characteristics;

(2) An internal and external examination of the portable tank and its fittings, taking into account the hazardous materials to be transported;

(3) A hydrostatic pressure test as specified in paragraph (i) of this section;

(4) A leakage test;

(5) A test of the satisfactory operation of all service equipment including pressure relief devices must also be performed. When the shell and its fittings have been pressure-tested separately, they must be subjected to a leakage test after reassembly. All welds subject to full stress level in the shell must be inspected during the initial test by radiographic, ultrasonic, or another suitable non-destructive test method. This does not apply to the jacket;

(6) A UN portable tank that meets the definition of “container” in the CSC (see 49 CFR 450.3(a)(2)) must be subjected to an impact test using a prototype representing each design type. The prototype portable tank must be shown to be capable of absorbing the forces resulting from an impact not less than 4 times (4 g) the maximum permissable gross mass of the fully loaded portable tank at a duration typical of the mechanical shocks experienced in rail transportation. A listing of standards describing methods acceptable for performing the impact test are provided in the UN Recommendations (incorporated by reference, see § 171.7 of this subchapter);

(7) The following tests must be completed on a portable tank that is also a CSC container without leakage or deformation that would render the tank unsuitable for transportation and use:

(i) Longitudinal inertia. The tank loaded to its maximum gross weight must be positioned with its longitudinal axis vertical. It shall be held in this position for five minutes by support at the lower end of the base structure providing vertical and lateral restraint and by support at the upper end of the base structure providing lateral restraint only.

(ii) Lateral inertia. The tank loaded to its maximum gross weight must be positioned for five minutes with its transverse axis vertical. It shall be held in this position for five minutes by support at the lower side of the base structure providing vertical and lateral restraint and by support at the upper side of the base structure providing lateral restraint only.

(e) Intermediate periodic inspection and test. The intermediate periodic inspection and test must include at least an internal and external examination of the portable tank and its fittings taking into account the hazardous materials intended to be transported; a leakage test; and a test of the satisfactory operation of all service equipment. Sheathing, thermal insulation, etc. need only to be removed to the extent required for reliable appraisal of the condition of the portable tank. For portable tanks intended for the transportation of a single hazardous material, the internal examination may be waived if it is leakage tested in accordance with the procedures in paragraph (i) of this section prior to each filling, or if approved by the Associate Administrator.

(f) Periodic inspection and test. The periodic inspection and test must include an internal and external examination and, unless excepted, a hydraulic pressure test as specified in this section. Sheathing, thermal insulation, etc. need only to be removed to the extent required for reliable appraisal of the condition of the portable tank. Reclosing pressure relief devices must be removed from the tank and tested separately. For portable tanks where the shell and equipment have been pressure-tested separately, after assembly they must be subjected together to a leakage test.

(g) Exceptional inspection and test. The exceptional inspection and test is necessary when a portable tank shows evidence of damaged or corroded areas, or leakage, or other conditions that indicate a deficiency that could affect the integrity of the portable tank. The extent of the exceptional inspection and test must depend on the amount of damage or deterioration of the portable tank. It must include at least the intermediate inspection and a hydrostatic test according paragraph (e) of this section. Pressure relief devices need not be tested or replaced unless there is reason to believe the relief devices have been affected by the damage or deterioration.

(h) Internal and external examination. The internal and external examinations must ensure that:

(1) The shell is inspected for pitting, corrosion, or abrasions, dents, distortions, defects in welds or any other conditions, including leakage, that might render the portable tank unsafe for transportation;

(2) The piping, valves, and gaskets are inspected for corroded areas, defects, and other conditions, including leakage, that might render the portable tank unsafe for filling, discharge or transportation;

(3) Devices for tightening manhole covers are operative and there is no leakage at manhole covers or gaskets;

(4) Missing or loose bolts or nuts on any flanged connection or blank flange are replaced or tightened;

(5) All emergency devices and valves are free from corrosion, distortion and any damage or defect that could prevent their normal operation. Remote closure devices and self-closing stop-valves must be operated to demonstrate proper operation;

(6) Required markings on the portable tank are legible and in accordance with the applicable requirements; and

(7) The framework, the supports and the arrangements for lifting the portable tank are in satisfactory condition.

(i) Pressure test procedures for specification 51, 57, 60, IM or UN portable tanks. (1) Each Specification 57 portable tank must be leak tested by a minimum sustained air pressure of at least three psig applied to the entire tank. Each Specification 51 or 56 portable tank must be tested by a minimum pressure (air or hydrostatic) of at least 2 psig or at least one and one-half times the design pressure (maximum allowable working pressure, or re-rated pressure) of the tank, whichever is greater. Leakage tests for all other portable tanks must be at a pressure of at least 25% of MAWP. During each air pressure test, the entire surface of all joints under pressure must be coated with or immersed in a solution of soap and water, heavy oil, or other material suitable for the purpose of detecting leaks, but in no case less than five minutes. The pressure must be held for a period of time sufficiently long to assure detection of leaks. During the air or hydrostatic test, relief devices may be removed, but all the closure fittings must be in place and the relief device openings plugged. Lagging need not be removed from a lagged tank if it is possible to maintain the required test pressure at constant temperature with the tank disconnected from the source of pressure.

(2) Each Specification 60 portable tank must be retested by completely filling the tank with water or other liquid having a similar viscosity, the temperature of which shall not exceed 100 °F during the test, and applying a pressure of 60 psig. The tank shall be capable of holding the prescribed pressure for at least 10 minutes without leakage, evidence of impending failure, or failure. All closures shall be in place while the test is made and the pressure shall be gauged at the top of the tank. Safety devices and/or vents shall be plugged during this test.

(3) Each Specification IM or UN portable tank, except for UN portable tanks used for liquefied compressed gases and all piping, valves and accessories, except pressure relief devices, must be hydrostatically tested with water, or other liquid of similar density and viscosity, to a pressure not less than 150% of its maximum allowable working pressure. UN portable tanks used for liquefied compressed gases must be hydrostatically tested with water, or other liquid of similar density and viscosity, to a pressure not less than 130% of its maximum allowable working pressure. The minimum test pressure for a portable tank is determined on the basis of the hazardous materials that are intended to be transported in the tanks. Minimum test pressure for specific hazardous materials are specified in the applicable T Codes assigned to a particular hazardous material in the § 172.101 Table of this subchapter. While under pressure the tank shall be inspected for leakage, distortion, or any other condition which might render the tank unsafe for service. A portable tank fails to meet the requirements of the pressure test if, during the test, there is permanent distortion of the tank exceeding that permitted by the applicable specification; if there is any leakage; or if there are any deficiencies. Any portable tank that fails must be rejected and may not be used again for the transportation of a hazardous material unless the tank is adequately repaired, and, thereafter, a successful test is conducted in accordance with the requirements of this paragraph. An approval agency shall witness the hydrostatic test. Any damage or deficiency that might render the portable tank unsafe for service shall be repaired to the satisfaction of the witnessing approval agency. The repaired tank must be hydrostatically retested. Upon successful completion of the hydrostatic test, the witnessing approval agency shall apply its name, identifying mark or identifying number in accordance with paragraph (l) of this section.

(j) Rejection criteria. When evidence of any unsafe condition is discovered, the portable tank may not be returned to service until it has been corrected and the pressure test is repeated and passed.

(k) Repair. The repair of a portable tank is authorized, provided such repairs are made in accordance with the requirements prescribed in the specification for the tank's original design and construction. In addition to any other provisions of the specification, no portable tank may be repaired so as to cause leakage or cracks or the likelihood of leakage or cracks near areas of stress concentration due to cooling metal shrinkage in welding operations, sharp fillets, reversal of stresses, or otherwise. No field welding may be done except to non-pressure parts. In all cases, when cutting, burning or welding operations on the shell have been affected, that work must be done with the approval of the approval agency and be done in accordance with the requirements of this subchapter, taking into account the pressure vessel code used for the construction of the shell. A pressure test to the original test pressure must be performed after the work is completed.

(l) Inspection and test markings. Each portable tank must be durably and legibly marked, in English, with the date (month and year) of the last hydrostatic test, the identification markings of the approval agency witnessing the test when required, and the date of the last visual inspection. The marking must be placed on or near the metal identification plate in letters not less than 3 mm (0.118 inches) high when on the metal identification plate and 32 mm (1.25 inches) high when on the portable tank.

(m) Record retention. The owner of each portable tank or his authorized agent shall retain a written record of the date and results of all required inspections and tests, and the name and address of the person performing the inspection or test, until the next retest has been satisfactorily completed and recorded. In addition, a manufacturer's data report of the portable tank must be procured and retained in the files of the owner during the time that such portable tank is used for such service, except for Specifications 56 and 57 portable tanks.
