SUPPLEMENTARY INFORMATION:

Background

This final rule will primarily reduce regulatory burdens on industry by incorporating changes into the Hazardous Materials Regulations (HMR) based on RSPA's own initiatives and petitions for rulemaking submitted in accordance with 49 CFR 106.95. In a continuing effort to review the HMR for necessary revisions, RSPA (“we” and “us”) is eliminating, revising, clarifying and relaxing regulatory requirements. On January 21, 2003, RSPA published a Notice of Proposed Rulemaking (NPRM) under Docket RSPA-02-13773 (HM-218B; 68 FR 2734). The NPRM contained information concerning each proposal and invited public comment. Readers should refer to the NPRM for additional background discussion.

RSPA received eleven comments in response to the NPRM. These comments were submitted by representatives of trade associations, such as the American Chemical Council, the American Pyrotechnics Association, and the Chlorine Institute; hazardous materials consulting firms; chemical manufacturers; and carriers of hazardous materials. Most commenters expressed support for various proposals, but several commenters raised concerns about certain provisions in the proposal that are discussed below.

The following is a section-by-section summary of changes and, where applicable, a discussion of comments received.

Section-by-Section Review

Part 171

Section 171.7

We are revising this section to update certain incorporation by reference materials and are adding three new entries. We are updating the following previously approved pamphlets and standards:

—CGA Pamphlet C-6.2, Guidelines for Visual Inspection and Requalification of Fiber Reinforced High Pressure Cylinders, 1996 edition. The 1996 edition of CGA Pamphlet C-6.2 simply makes editorial changes to the 1988 edition.

—CGA Pamphlet C-11, Recommended Practices for Inspection of Compressed Gas Cylinders at Time of Manufacture, 2001 edition. This new edition of CGA Pamphlet C-11 adds Transport Canada requirements and clarifies existing text.

—CGA Pamphlet C-13, Guidelines for Periodic Visual Inspection and Requalification of Acetylene Cylinders, 2000 edition. This new edition of CGA Pamphlet C-13 adds acetylene cylinders to the rejection criteria, allows condemned acetylene cylinders to be permanently marked as such, and changes the time parameters for requalification of the porous mass.

—CGA Pamphlet S-1.1, Pressure Relief Device Standards—Part 1—Cylinders for Compressed Gases, 2001 edition (with the exception of paragraph 9.1.1.1). This new edition adds a definition and requirements for the new PRD CG-10 device.

—NFPA 58—Liquefied Petroleum Gas Code, 2001 edition.

We are also incorporating by reference the 2001 edition of the American Pyrotechnics Association's Standard 87-1, Standard for Construction and Approval for Transportation of Fireworks, Novelties, and Theatrical Pyrotechnics, which establishes a ten-inch limit on aerial shells for fireworks that may be classed as Division 1.3 explosives.

We are updating the entry for the Association of American Railroads (AAR) Manual of Standards and Recommended Practices, Section C—Part III, Specifications for Tank Cars, Specification M-1002 by adding the 2000 edition and removing the entries for the 1992 and 1996 edition.

We are adding the American Society for Testing and Materials (ASTM) E 114-95 test method for straight beam examination of the tubular surface of cylinders and tubes which is used in conjunction with ASTM E 213-98 to measure the wall thickness of a cylinder and to detect general corrosion and defects located in the path of the ultrasonic straight beam direction. ASTM E 213-98 was incorporated by reference in a final rule published in the Federal Register on August 8, 2002 (Docket HM-220D, 67 FR 51626). Two commenters requested we incorporate by reference the ASTM E 114-95 (2001) test method and the ASTM E 213-02 to reflect the latest version of these standards. Because we did not propose to incorporate the newer editions of these standards in the NPRM, we are not incorporating them at this time. These standards may be considered for incorporation by reference in a future rulemaking.

We are also adding the Chlorine Institute's booklets entitled “Chlorine Institute Emergency Kit ‘A’ for 100-lb. & 150-lb. Chlorine Cylinders” and “Chlorine Institute Emergency Kit ‘B’ for Chlorine Ton Containers”. (See § 173.3 preamble discussion.)

Section 171.15

In the NPRM we proposed to move a shipper requirement to notify the Bureau of Explosives (BOE) whenever a rail car containing a time-sensitive product is not received by the consignee within 20 days from shipment from Start Printed Page 48563§§ 173.314(g)(1) and 173.319(a)(3) to § 171.15. We also proposed to require notification to the Federal Railroad Administration (FRA) instead of the BOE by “the person with knowledge (shipper or carrier).” Commenters generally supported notification to the FRA, however, two commenters opposed moving the reporting requirements into § 171.15 because “the reporting requirement for late delivery of time sensitive materials does not meet the criteria of reporting under § 171.15.” The commenters opposed assignment of the reporting responsibility to “the person with knowledge (shipper or carrier)” and said this language is not specific enough and could cause “instances of noncompliance” where the shipper believes the carrier is the “person with knowledge” and vice versa. Commenters are also divided on who should be assigned the reporting responsibility. Some commenters want the responsibility assigned to the shipper, others to the carrier. Another commenter objected to having to choose from multiple telephone numbers depending on time of day to report these late shipments. Based on valid concerns from commenters that the reporting requirements for late shipments do not fit the reporting criteria under § 171.15 and the various other issues raised by commenters that we need to further review, we are not adopting this proposal at this time.

Part 172

Section 172.101

We are amending the entry for “Butylene” by adding a limited quantity exception for compressed gases (see § 173.306) in column (8A) of the Hazardous Materials Table (HMT). This amendment corrects an oversight in previous rulemakings and is consistent with the entries for “Petroleum gases, liquefied” and other hydrocarbons.

We are adding a new domestic entry for “Cartridges power devices, ORM-D” to the HMT for consistency with the packaging exceptions authorized in § 173.63(b). This entry is limited to those cartridges, small arms and cartridges power devices which are authorized to be reclassed and shipped as ORM-D in § 173.63(b)(1).

For Zone B Toxic Inhalation Hazard entries with ID numbers UN3303, UN3304, UN3305, UN3306, UN3307, UN3308, UN3309, and UN3310, we are amending the HMT by adding Special Provisions B9 and B14; and for Zone C Toxic Inhalation Hazard entries with the same ID numbers, we are adding Special Provision B14. The special provisions were inadvertently omitted in previous rulemakings.

In the NPRM, we proposed to remove the letter “I” in column (1) of the HMT for compressed gas entries with ID numbers UN 3304, UN 3305, and UN 3306 and liquefied gas entries with ID numbers UN 3308, UN 3309 and UN 3310. The letter “I” identifies proper shipping names which are appropriate for describing materials in international transportation. A commenter pointed out that removal of the letter “I” in column 1 of the HMT from these Division 2.3 materials, which show a Class 8 subsidiary hazard, is inappropriate because the definition of Class 8 in § 173.136 is limited to solid and liquid materials. A Class 8 subsidiary hazard for Division 2.3 materials is only prescribed under international regulations. RSPA agrees with the commenter; therefore, this proposal is not adopted.

For the entry “Liquefied gas, toxic, oxidizing, corrosive, n.o.s.” Hazard Zones B, C and D, we are correcting a typographical error in the subsidiary labeling requirements by removing the Division 2.1 label requirement and adding the Division 5.1 label in its place.

We are revising the entry for “Gas sample, non-pressurized, toxic, n.o.s., UN 3169” by adding Special Provision 6 in column (7) of the HMT. The entry is classed as a Division 2.3 poisonous gas and must be described as an inhalation hazard under the provisions of the HMR. A commenter pointed out that the entry “Gas sample, non-pressurized, toxic, flammable, n.o.s., UN 3168” which is also a Division 2.3 gas and must be described as an inhalation hazard material, should also be assigned Special Provision 6. We agree with the commenter and are revising the entry for “Gas sample, non-pressurized, toxic, flammable, n.o.s., UN 3168” in the HMT accordingly.

Section 172.504

We are revising paragraph (d) to clarify that the placarding exception for non-bulk packagings containing only the residue of a hazardous material covered by table 2 does not apply to materials subject to the subsidiary placarding requirements in § 172.505 (e.g., poison inhalation hazard). A material subject to the subsidiary placarding requirements in § 172.505 requires placarding for the subsidiary hazard in addition to any other required placards regardless of quantity.

Part 173

Section 173.3

We are revising § 173.3 to allow a DOT 3A480 or 3AA480 cylinder containing chlorine or sulphur dioxide (both materials poisonous by inhalation) that has developed a leak in the valve or fusible plug to be temporarily repaired using a Chlorine Institute Emergency Kit “A” and be transported by private or contract carrier one time, one way, from the point of discovery to the appropriate facility for discharge and examination. Similarly, we are allowing a DOT 106A500 multi-unit tank car tank containing chlorine or sulphur dioxide that has developed a leak in the valve or fusible plug to be temporarily repaired using a Chlorine Institute Emergency Kit “B.” We have authorized the use of the kits under the exemption program for several years with satisfactory shipping experience. Adopting these exemption provisions into the regulations will eliminate the need for an exemption and facilitate the movement of affected containers to appropriate facilities. We are also correcting a typographical error in the paragraph (d) heading to read “DOT 106A500” instead of “DOT 105A500”. The commenters supported the proposal; however, several commenters requested that use of the “A” and “B” kits be extended to other specification packagings as well as to other compressed gases. Our proposal in the NPRM is based on a satisfactory shipping record under the exemption program using the “A” kits to temporarily repair leaking 3A480 and 3AA480 cylinders and the “B” kits to temporarily repair DOT 106A500 multi-unit tank car tanks containing chlorine or sulphur dioxide. Therefore, we are adopting the amendment as proposed. While other materials might develop a satisfactory shipping record if tested, neither RSPA nor FRA is aware of significant experience in the use of “A” or “B” kits for commodities other than chlorine or sulphur dioxide or for containers other than the specification 3A480/3AA480 cylinders or DOT 106A500 multi-unit tank car tanks. Proponents of this expansion have not presented sufficient or convincing evidence to substantiate a more extensive amendment to the HMR. Including other types of packagings and materials is outside the scope of this rulemaking and may be considered in a future rulemaking.

Section 173.12

We are revising § 173.12(c) to authorize the reuse of packagings for shipments of all wastes, not just waste Start Printed Page 48564materials subject to EPA waste manifest requirements, to designated facilities. This includes shipments of spent/waste materials which are being returned to or shipped to an EPA licensed and certified Storage or Disposal facility, but are not subject to the Uniform Hazardous Waste Manifest requirements of the U.S. Environmental Protection Agency.

Section 173.29

We are revising paragraph (c) to clarify that the placarding exceptions for non-bulk packages containing only the residue of a § 172.504 Table 2 material do not apply to materials subject to the subsidiary placarding requirements in § 172.505. A material subject to the subsidiary placarding requirements in § 172.505 requires placarding for the subsidiary hazard in addition to any other required placards regardless of quantity.

Section 173.31

We are adding a new paragraph authorizing the continued use of existing DOT-103 and 104 tank cars, if they meet all applicable requirements. No new construction of these tanks is authorized. We are also revising paragraph (b)(2)(ii) for clarity by removing the reference to “Chloroprene, inhibited” since Special Provision B57 addresses the requirements for chloroprene in class DOT-115A tank cars, and by removing the last sentence since “breather holes” are not authorized in the HMR. In addition, we are revising paragraph (b)(5) to reflect changes to Appendix Y of the AAR Specifications for Tank Cars. This change recognizes the 2000 edition of Appendix Y in the AAR Tank Car Manual.

Section 173.35

In paragraph (b), we are adding, for purposes of clarification, a parenthetical cross-reference to § 180.352 that contains detailed requirements for retest and inspection of IBCs.

Section 173.50

We are adding a statement indicating that pyrotechnic substances and articles are considered explosives unless otherwise classed. The definition of “explosive” in § 173.50 previously did not specifically include pyrotechnics.

Section 173.54

We are revising paragraph (c) to forbid offering for transportation a leaking or damaged article, even if not in a package. This is in addition to the existing prohibition of offering a leaking or damaged package of explosives for transportation.

Section 173.62

We are revising paragraph (c), in the table of Packing Methods, to clarify that Packing Instruction 132(a) applies to articles with closed casings and Packing Instruction 132(b) applies to articles without closed casings.

Section 173.314

We are removing the wording “safety relief” and adding the wording “reclosing pressure relief” in its place in paragraphs (k) and (m) for consistency.

Section 173.315

Currently, the HMR appear to require that cargo tank motor vehicles (CTMVs) that transport Division 2.2 materials with a subsidiary hazard, Division 2.1 materials, and anhydrous ammonia in both metered and other than metered delivery service must be equipped with both a passive and an off-truck remote means of emergency discharge control. We are revising § 173.315(n)(1)(vi) to permit CTMVs in both metered and other than metered delivery service, with capacities of more than 3,500 water gallons, used to transport Division 2.2 materials with a subsidiary hazard, Division 2.1 materials, and anhydrous ammonia to be equipped with only a passive means of emergency discharge control, provided that the system functions for both metered and non-metered deliveries. If the system functions only for non-metered deliveries, then the CTMV must also be equipped with an off-truck remote emergency discharge control system.

Section 173.320

We are amending paragraph (a)(2) by adding the requirements in subparts G (Emergency Response Information) and H (Training) of part 172 for transportation of cryogenic liquids by rail or highway. We never intended to except shipments of cryogenic liquids from these requirements.

Part 177

Section 177.834

We are amending § 177.834(a) to require that any packaging containing a hazardous material, regardless of Class or Division, be secured against movement if the packaging is not permanently attached to a motor vehicle. We are also incorporating into paragraph (a) the closely related requirements in § 177.834(g) to prevent relative motion between the hazardous material packages themselves and between packages and the vehicle and to ensure that packages that have valves or other fittings be loaded in a manner that minimizes the likelihood of damage during transportation to the valves, other fittings or, as clarified in this final rule, other hazardous materials packages. Securement of packages containing hazardous materials to prevent movement during transportation reduces the potential for damage to packages and thus, enhances transportation safety.

Also, for consistency with similar requirements in Parts 174, 175, and 176, we are adding a new paragraph (b) to clarify that packages bearing orientation markings must be loaded in such a way that they remain in the correct position as indicated by the markings.

Section 177.835

Currently § 177.835 prohibits carrying a Division 1.1 or Division 1.2 material on any vehicle or a combination of vehicles if the other vehicle is carrying a Division 2.3 or Division 6.1 material. The segregation table in § 177.848 restricts loading and transporting of a Division 1.1 or 1.2 material with a material in Division 2.3, Hazard Zone A or B, and in Division 6.1, PG I, Hazard Zone A. For consistency with the provisions in § 177.848(d), we are revising § 177.835(c)(4)(iii) to limit the segregation restriction for a Division 1.1 or Division 1.2 explosive material to Division 2.3 materials in Hazard Zone A or B and to Division 6.1, PG I materials in Hazard Zone A.

Section 177.837

We are amending paragraph (a) to permit the diesel engine of a cargo tank motor vehicle to be running during loading and unloading of Class 3 materials if the ambient temperature is at or below −12 °C (10 °F). A motor vehicle's diesel engine is very difficult to restart if the engine is turned off in extremely cold weather for loading or unloading of product. Leaving a motor vehicle engine running in ambient temperatures of below −12 °C (10 °F) enhances operating benefits without compromising safety.

Section 177.841

We are revising paragraph (e) to expand the prohibition of transporting packagings bearing or required to bear a POISON or POISON INHALATION HAZARD label to include packagings that are placarded or required to be placarded POISON or POISON INHALATION HAZARD. Under § 172.514(c) certain small bulk packagings may either be placarded or labeled. Start Printed Page 48565

Part 178

Section 178.45

We are revising paragraph (h) to authorize use of the ASTM E 114 test method for straight beam examinations on the tubular surface of cylinders and tubes as stated earlier in this preamble in the discussion to § 171.7.

Part 179

We are removing the specifications and all references to class DOT-103 and 104 tanks cars from this part since new construction of these tank cars is no longer authorized. (Continued use of class DOT-103 and 104 tank cars is authorized in §§ 173.31 and 180.507.)

Section 179.1

Paragraph (a) implies that only tanks used to transport hazardous materials are subject to the jurisdiction of DOT. For consistency with §§ 171.2(c) and 180.3(a), we are revising paragraph (a) to clarify that any tank represented as a DOT specification tank, even when used to transport non-regulated commodities, is subject to the HMR.

Section 179.3

We are revising § 179.3 for clarity.

Section 179.5

We are revising this section by removing an obsolete requirement to furnish a Certificate of Construction to DOT.

Section 179.7

In paragraph (f), we are removing an outdated compliance date.

Section 179.100-13

In paragraphs (b) and (c), we are adding, for purposes of clarification, a reference to § 173.314(j), which contains excess flow valve requirements for flammable gases.

Part 179 Subpart D

In the heading for Subpart D, we are removing the reference to class DOT-103 and DOT-104 tank cars.

Section 179.200

In the section heading, we are removing the reference to class DOT-103 and DOT-104 tank cars.

Section 179.200-14

In the NPRM, we proposed to remove the reference to class DOT-103 and DOT-104 tank cars in paragraph (a). In this section, for the convenience of HMR readers, because the continued use of Class DOT 103 and 104 tank cars is authorized, we are not adopting this proposal.

Section 179.200-23

We are amending the section heading by removing the words “safety relief” and adding “pressure relief” in their place.

Section 179.200-24

We are amending the table by removing the reference to a class DOT-103W tank car and adding a reference to a class DOT-111A tank car in its place.

Section 179.201-1

We are amending the table by removing the entries for class DOT-103 and DOT-104 tank cars because new construction of these tank cars is no longer authorized. (Continued use of class DOT-103 and 104 tank cars is authorized in §§ 173.31 and 180.507.)

Section 179.201-2

Section 179.201-2 addresses minimum plate thickness for DOT specification tank cars that may no longer be constructed. Therefore, § 179.201-2 is removed and reserved.

Section 179.201-3

We are amending paragraph (b) by removing the reference to DOT-103 tank cars.

Section 179.300-17

In this final rule, in § 171.7 we are amending the “Table of material incorporated by reference” by updating the entry for the AAR Specifications for Tank Cars from the 1996 edition to the 2000 edition. See § 171.7 preamble discussion. Therefore, we are amending paragraph (b) for clarity and removing the reference to the January 1996 edition of the AAR Specifications for Tank Cars.

Part 180

Section 180.209

In this final rule, we are incorporating by reference CGA Pamphlet C-13, Guidelines for Periodic Visual Inspection and Requalification of Acetylene Cylinders (see § 171.7 preamble). CGA Pamphlet C-13 changes the time parameters for requalification of the porous mass of acetylene cylinders from “no sooner than 3 years” to “no sooner than 5 years.” Consequently, we are also revising paragraph § 180.209(i) to reflect this change.

Section 180.507

We are adding a new paragraph authorizing the continued use of DOT 103 and 104 tank cars, which may no longer be constructed.

Regulatory Analyses and Notices

A. Executive Order 12866 and DOT Regulatory Policies and Procedures

This final rule is not considered a significant regulatory action under section 3(f) of Executive Order 12866. Therefore, it was not reviewed by the Office of Management and Budget (OMB), and a regulatory assessment was not required for OMB. This final rule is not considered to be significant under the Regulatory Policies and Procedures order issued by the U.S. Department of Transportation (44 FR 11034) and, therefore, a Regulatory Analysis under the DOT order is not required.

In this final rule, we are amending miscellaneous provisions in the HMR to clarify the provisions and to relax requirements where warranted; responding to requests from industry associations to update references to standards that are incorporated in the HMR, and making certain technical corrections. These changes will enhance safety. The impact of these amendments is believed to be so minimal that a regulatory evaluation is not warranted. In the NPRM, we invited public comments on any impacts of the proposed changes. We did not receive any comments regarding the impacts of these changes.

B. Executive Order 13132

This final rule was analyzed in accordance with the principles and criteria contained in Executive Order 13132 (“Federalism”). Federal law expressly preempts State, local, and Indian tribe requirements, applicable to the transportation of hazardous materials, that cover certain subjects and are not substantively the same as the Federal requirements. 49 U.S.C. 5125(b)(1). These subjects are:

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

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

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

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

(v) The design, manufacturing, fabricating, marking, maintenance, reconditioning, repairing, or testing of a packaging or container which is represented, marked, certified, or sold as qualified for use in the transport of hazardous materials. Start Printed Page 48566

This final rule concerns the classification, packaging, marking, labeling, and handling of hazardous materials, among other covered subjects and preempts any State, local, or Indian tribe requirements concerning these subjects unless the non-Federal requirements are “substantively the same” (see 49 CFR 107.202(d)) as the Federal requirements.

Federal hazardous materials transportation law provides at 49 U.S.C. 5125(b)(2) that if RSPA issues a regulation concerning any of the covered subjects, RSPA 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. The effective date of preemption is 90 days from the publication of this final rule in the Federal Register.

C. Executive Order 13175

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

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

The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an agency to review regulations to assess their impact on small entities. An agency must conduct a regulatory flexibility analysis unless it determines and certifies that a rule is not expected to have a significant impact on a substantial number of small entities. This final rule amends miscellaneous provisions in the HMR to clarify provisions based on our own initiative and also on petitions for rulemaking. While maintaining safety, it relaxes certain requirements that are overly burdensome and updates references to consensus standards that are incorporated in the HMR.

These amendments are generally intended to provide relief to shippers, carriers, and packaging manufacturers, including small entities. In addition, we are updating references to standards that are incorporated in the HMR; industry associations, representing large and small entities, requested these changes.

This final rule enhances safety, and I certify that this final rule does not have a significant economic impact on a substantial number of small entities.

This final rule has been developed in accordance with Executive Order 13272 (“Proper Consideration of Small Entities in Agency Rulemaking”) and DOT's procedures and policies to promote compliance with the Regulatory Flexibility Act to ensure that potential impacts of draft rules on small entities are properly considered.

E. Paperwork Reduction Act

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

F. Unfunded Mandates Reform Act

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

G. Environmental Assessment

There are no significant environmental impacts associated with this final rule. An environmental assessment is available in the docket for this rulemaking. We received no comments concerning environmental impacts.

H. 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.
