SUPPLEMENTARY INFORMATION: Background This NPRM is designed primarily to reduce regulatory burden on industry by incorporating changes into the HMR based on RSPA's own initiative and petitions for rulemaking submitted in accordance with 49 CFR 106.31. This NPRM also is consistent with the goals of the President's Regulatory Reinvention Initiative. On March 4, 1995, the President directed Federal agencies to perform an extensive review of all agency regulations and eliminate or revise those requirements that are outdated or in need of reform. In a continuing effort to review the HMR for necessary revisions, RSPA is also proposing to eliminate, revise, clarify and relax certain other regulatory requirements. The following is a section-by-section summary of the proposed changes. Section-by-Section Review Part 171 Section 171.7 RSPA proposes to update the incorporation by reference of the American Society of Mechanical Engineers (ASME) Code to the 1998 Edition. Currently, the 1992 Edition and the Addenda through December 31, 1993 are incorporated by reference. After a review, RSPA believes that the 1998 Edition should be incorporated by reference. However, at this time RSPA is not proposing to adopt any Addenda to the 1998 Edition of the ASME Code because we have not fully reviewed them. Section 171.8 The definition for ``Aerosol'' would be revised to remove reference to a ``metal'' receptacle to align the HMR with the UN Recommendations. RSPA proposes to revise the definition for ``EX number.'' Currently, the definition states that an EX number is assigned by the Associate Administrator for Hazardous Materials Safety (AAHMS) to identify an explosive which has been approved. However, RSPA presently assigns EX numbers to track materials evaluated by the AAHMS under the provisions of Sec. 173.56, regardless of whether or not they are approved under a different hazard class. The definition for ``Placarded car'' would be revised to remove reference to a ``FUMIGATION placard.'' As used in the HMR, a railcar containing lading which has been fumigated or is undergoing fumigation is required to display the ``FUMIGANT marking'' shown in Sec. 173.9. Section 171.11 RSPA is proposing to remove paragraph (d)(5), which requires the identification of a poison material on the shipping paper. The International Civil Aviation Organization (ICAO) Technical Instruction already requires the shipping paper to identify subrisks and RSPA believes paragraph (d)(5) is unnecessary. RSPA is proposing to add a new paragraph (d)(5) to require that the original approval (EX) number or traceable product code issued to an air bag inflator or seat-belt pretensioner be entered on the shipping paper in association with the basic description, as specified in Sec. 173.166 (c). Currently, shipping papers for devices offered under the ICAO Technical Instruction are not required to contain the EX number or product code for an approved inflator or pretensioner. RSPA believes this shipping paper provision should include air bags or seat-belt pretensioners when offered and transported in the United States under the authority of international regulations. Devices containing a pressure vessel and transported as Division 2.2 (UN3353) would be excluded from this shipping paper notation requirement. In addition, paragraph (d)(14) would be revised to clarify that ``Aerosols'' transported in the U.S. under the provisions of the ICAO Technical Instructions must be in metal packagings if the packaging exceeds 7.22 cubic inches. Section 171.12 RSPA is proposing to revise paragraph (a) to clarify that the shipping paper documentation required under the International Maritime Dangerous Goods Code (IMDG) or International Atomic Energy Agency (IAEA) must be written in English as currently required by Sec. 172.201(a)(2). Similar to the proposed change to Sec. 171.11 above, RSPA proposes to add paragraph (b)(5) to require that the approval (EX) number or traceable product code be entered on shipping papers for airbag inflators and seat belt pretensioners offered under the International Maritime Dangerous Goods (IMDG) Code. Part 172 Section 172.101 Paragraphs (b)(2) and (b)(6) would be revised to clarify that proper shipping names denoted with an ``A'' or ``W'' in Column (1), in the HMT, may be used to describe hazardous materials transported by all modes when all applicable requirements are met. RSPA proposes to remove paragraph (c)(8), which is specific to determining [[Page 53167]] a proper shipping description for hazardous substances as it is redundant with Sec. 172.101(c). Paragraph (c)(8) would be replaced to allow the words ``liquid'' or ``solid'' to be added to a proper shipping name when a hazardous material specifically listed by name may due to differing physical states be a liquid or solid. This is consistent with existing provisions in the UN Recommendations, the ICAO TI and the IMDG Code. The entry ``Chemical kits or First aid kits (containing hazardous materials)'' would be separated into two individual entries for easier reference. In addition, the wording ``(containing hazardous materials)'' is unnecessary and would be removed. The entry `` 1-chloro-3-bromopropane'' would be changed to read ``1-bromo-3-chloropropane'' to be in accordance with the UN Recommendations. A new entry ``Fumigated transport vehicle or freight container, see Sec. 173.9'' would be added to reference Sec. 173.9 which contains requirements for transporting fumigated lading. This change would facilitate the location of these requirements by readers. For the entries, ``Polychlorinated biphenyls, liquid'' and ``Polychlorinated biphenyls, solid,'' UN2315, in Column 1, the symbols ``A, W'' would be removed and a new Special Provision 140 would be added in Column 7. Special Provision 140 would state that the material is only regulated when it meets the defining criteria for a hazardous substance or a marine pollutant. For the entry ``Air, compressed,'' Special Provision 78 would be added in Column 7 to specify that only mixtures with not more than 23.5 percent oxygen may be transported under this entry. An OXIDIZER label is not required for mixtures containing not more than 23.5 percent oxygen. This change will align the HMR with a recent amendment adopted in the eleventh revised edition of the UN Recommendations. In addition, for the entry ``Rare gases and oxygen mixtures, compressed,'' Special Provision 79 would be added to state that this entry may not be used for mixtures meeting the criteria for oxidizing gas in Sec. 171.8. RSPA believes that it is more appropriate to use a generic oxidizing gas entry (i.e., Compressed gas, oxidizing, n.o.s.) when such mixtures meet the criteria of an oxidizing gas. For the entry, ``Sodium chlorate, aqueous solution,'' PG II, Special Provision ``B6'' would be removed. It was pointed out to RSPA that similar entries (Potassium chlorate, aqueous solution and Chlorates, inorganic, aqueous solution) are not assigned this Special Provision. RSPA agrees that the Special Provision was mistakenly assigned. In response to comments submitted by the Vessel Operators Hazardous Materials Association (VOHMA), in response to the NPRM of HM-215C, RSPA is proposing to revise a number of HMT entries with inconsistently applied Codes 34 and 95 in column 10B. These codes pertain to segregation of Division 2.3 and 6.1 and Class 8 hazardous materials with foodstuffs. These changes will align the HMR with the IMDG Code. In total, there are twenty (20) deletions of Code 95, nine (9) additions of Code 95, three (3) changes from Code 34 to 95, and three (3) deletions of Code 34 from Column 10B. Section 172.102 In paragraph (c)(1), a new Special Provision 78 would be added to specify that the entry ``Air, compressed'' may not be used to describe compressed air which contains more than 23.5% of oxygen. This change would align the HMR with a recent amendment adopted in the eleventh revised edition of the UN Recommendations. In addition, a new Special Provision 79 would be added to specify that the entry ``Rare gases and oxygen mixtures, compressed'' may not be used for gas mixtures which meet the criteria for an oxidizing gas. This change would ensure that the correct emergency response information is provided for mixtures which meet the criteria for oxidizing gas. We are also proposing to add a new Special Provision 140 to the entries ``Polychlorinated biphenyls, liquid'' and ``Polychorinated biphenyl, solid,'' UN 2315 to state that the material is only regulated when it meets the defining criteria for a hazardous substance or marine pollutant. This change would be consistent with international regulations. We propose, in paragraph (c)(5), to revise Special Provision N10 regarding lighters. Currently, approvals for lighters require the approval number to be marked on the package and on the shipping papers. We believe that this requirement should be contained in the regulations. Section 172.201 Paragraph (a)(1)(ii) would be revised to clarify that when a reproduced shipping paper identifies hazardous materials entries by highlighting the basic description in a contrasting color, the packing group must be highlighted. The packing group is identified as a basic description element by Sec. 172.202(a)(4) and (b). Section 172.204 For consistency with paragraphs (a)(1), (a)(2) and the ICAO Technical Instructions, paragraph (c)(1) would be revised to change the word ``packed'' to read ``packaged.'' A transition period of 10 years would be provided for depletion of preprinted shipping papers showing the word ``packed'' to reduce costs. Sections 172.332 and 172.336 In response to a petition for rulemaking from the American Trucking Association (ATA) [P-1364], RSPA proposes to amend Secs. 172.332(a) and 172.336(b) to authorize the use of white square-on-point configurations for display of identification number markings regardless of whether a placard is required for that material. RSPA agrees with ATA that it is unnecessarily restrictive to prevent the use of identification number markings displayed on square-on-point configurations in conjunction with placards. Section 172.504 RSPA proposes to revise the Class 9 table entry to reference Sec. 172.504(f)(9), which provides an exception from displaying a Class 9 placard for domestic transportation. In addition, paragraph (f)(8), regarding the placarding of a material classed as a combustible liquid that also meets the definition of a Class 9, would be removed. A new paragraph (f)(8) would be added to provide an exception, in domestic transportation, for placarding a transport vehicle displaying a POISON INHALATION placard if it is already placarded with a POISON GAS placard. Section 172.516 Paragraph (a) would be revised by changing the wording ``motor vehicle'' to ``transport vehicle'' the second time it appears in the first sentence, to correct an inaccurate usage of the term ``motor vehicle''. This change clarifies that each placard on a motor vehicle must be clearly visible from the direction it faces, except from the direction of another transport vehicle to which the motor vehicle is coupled. Section 172.519 Paragraph (b)(3) would be revised to clarify that text is required on the DANGEROUS placard. In addition, the provision would be revised to clarify that text is not required on an OXYGEN placard when the specific identification number is displayed. [[Page 53168]] Section 172.604 Paragraph (c)(2) would be revised to clarify that hazardous materials transported under the proper shipping name ``Consumer commodity'' do not require emergency response information, regardless of whether the hazard class is ``ORM-D'' as provided by the HMR, or ``9'' as provided by the ICAO Technical Instructions. Section 172.704 In Sec. 172.704, paragraph (b) would be revised to add the reference, ``29 CFR 1910.1200,'' in addition to 29 CFR 1910.120 of the Department of Labor's Occupational Safety and Health Administration (OSHA). This change is needed to clarify that any training received due to OSHA's requirements need not be repeated to meet DOT training requirements. Part 173 Section 173.4 RSPA proposed to revise paragraphs (a)(1)(i) (ii) and (iii) to clarify that the limit of one gram for Division 6.1 material per inner receptacle applies only to materials that are poisonous by inhalation. In addition, RSPA proposes to add a note to Sec. 173.4(a)(6)(ii) to clarify that one package need not be subjected to all of the tests specified in Sec. 173.4; a separate, but identical, packaging may be used for each test. Section 173.5 In Sec. 173.5, paragraph (a) would be revised to grant an exception from the emergency response and training requirements in subparts G and H of Part 172 respectively to Class 2 agricultural products that are transported over local roads between fields of the same farm. Currently, agricultural products other than Class 2 materials are completely excepted from the HMR when transported between fields of the same farm. RSPA believes that similar relief is warranted for Class 2 materials. Section 173.7 We are proposing to add a new paragraph (e) which would incorporate and expand the existing exception in Sec. 173.62, paragraph (d) for Class 1 explosives owned by the Department of Defense (DOD). Section 173.62, paragraph (d) would be deleted. Currently DOD is authorized to ship their Class 1 materials that were packaged prior to January 1, 1990, without regard to the current packaging requirements in Part 178. In addition to the existing exception, we are proposing to also except these packagings from the marking and labeling requirements. This would alleviate the need to remark and re-label DOD stockpiled hazardous materials. Considering that the revised exception applies to marking and labeling of DOD packagings in addition to packaging requirements, RSPA believes it is more appropriate that the exceptions appear in Sec. 173.7. Section 173.12 In Sec. 173.12, paragraph (b)(3) would be revised to clarify that materials poisonous by inhalation are not authorized for the lab pack provisions. Section 173.13 In Sec. 173.13, paragraph (a) would be revised to clarify that use of the CARGO AIRCRAFT ONLY label is required. As discussed in the preamble to Docket HM-222 [May 30,1996; 61 FR 27169], it was RSPA's intention to except use of primary and subsidiary hazard labels only. Hazardous materials transported under the provisions of Sec. 173.13 are not authorized for transportation by passenger carrying aircraft. When transported without the CARGO AIRCRAFT ONLY label, RSPA believes that some packagings offered for transportation under Sec. 173.13 may inadvertently be placed on a passenger carrying aircraft in violation of the HMR. This change would be consistent with Sec. 172.402(c) regarding display of the CARGO AIRCRAFT ONLY label. Section 173.32 In Sec. 173.32, we propose to amend paragraph (e)(3) to authorize smaller markings on specification portable tanks that were originally authorized to be marked with letters and numerals as small as 1/8 of an inch in height. The specification plates originally attached to these packagings do not have sufficient space to accommodate larger size markings after retesting. Section 173.60 In Sec. 173.60, a new paragraph (b)(14) would be added consistent with the UN Recommendations to allow large explosive articles normally intended for military use, to be transported unpackaged under specific conditions. This provision is currently found in Sec. 173.62 Packing Instruction (PI) 130; however, the provision only applies to those explosives assigned to PI 130. Inclusion of this new paragraph would allow any large explosive article normally intended for military use to be transported unpackaged under the specified conditions. Section 173.61 In Sec. 173.61, paragraph (a) would be revised to clarify that explosives may be packed with non hazardous materials that will not adversely affect the explosive. RSPA believes that relaxation of this provision will avoid the need for exemptions. Section 173.62 In Sec. 173.62, paragraph (d) would be removed. Reference the preamble discussion under Sec. 173.7. Section 173.150 RSPA proposes to remove the wording ``and combustible liquids'' in the first sentence of Sec. 173.150(b). Referring to combustible liquids is unnecessary because there is no requirement for labeling or specification packaging. In addition, paragraph (f)(3)(iv) would be revised to clarify that placards are not required for a combustible liquid that is a hazardous substance, hazardous waste or marine pollutant in a non-bulk packaging. We propose to revise paragraph (f)(3)(viii) by changing a reference from Sec. 177.834 to Sec. 177.834(j). Paragraph (j) requires that manholes and valves be closed during transportation. This proposed change would clarify that combustible liquids are not subject to other provisions of Sec. 177.834, such as those pertaining to attendance, and is responsive to a petition for rulemaking (P-1386) from the Petroleum Marketers Association of America. Section 173.166 We propose to revise the introductory text in paragraph (e) to clarify that all airbag modules and inflators and seat belt pretensioners including those in Division 2.2 that are transported under UN 3353 must be packaged in UN packagings meeting the Packing Group III performance level. At present, since no packing group is provided in Sec. 172.101 for UN 3353, the required level of testing for UN packagings authorized for use in paragraph (e) for devices transported under UN 3353 is not stated in the HMR. The proposal to require a Packing Group III performance level is consistent with the provisions in the eleventh revised edition of the UN Recommendations. We also propose to authorize an air bag module or a seat belt pretensioner that has been removed from a motor vehicle that was manufactured as required for use in the United States to be offered for transportation in commerce without marking the EX number or product code on the shipping paper, as required by current paragraph (c). Instead, the word ``Recycled'' would [[Page 53169]] be entered immediately after the basic description prescribed in Sec. 172.202. This proposed change will facilitate transportation of these devices for recycling and eliminate the need for exemption, DOT-E 12189 granted to the Automotive Recyclers Association and several other grantees. Section 173.242 In paragraph (c)(1), a reference to obsolete Sec. 178.253-4 would be removed and replaced with the specific portable tank venting requirements that were contained in that section. Section 173.247 Paragraph (g)(1)(iii)(C) would be revised to clarify the pressure relief device requirements for bulk packagings transported by rail. The current regulatory text may be misunderstood as requiring the use of a combination pressure relief device, such as a reclosing pressure relief device (a safety valve) incorporating a rupture disc on the upstream side. The paragraph would be revised to clarify the requirement for a nonreclosing pressure relief device that incorporates a rupture disc conforming to the requirements of Sec. 179.15. Section 173.306 Paragraph (h)(2) would be revised to clarify that shipping papers are required for a Class 2 material that has been reclassed as a consumer commodity if it also meets the definition for ``marine pollutant.'' This change would provide consistency with corresponding HMR limited quantity provisions. Section 173.307 Paragraph (a)(4) would be revised to except from the HMR, refrigerating machines, including dehumidifiers and air conditioners and components thereof, containing up to 12 kg (25 pounds) or less of a non-flammable, non-toxic gas; 12 L (3 gallons) or less of ammonia solution (UN2672) and except for air transportation, 12 kg (25 pounds) of flammable non-toxic gas, and 20 kg (44 pounds) or less of a Group A1 refrigerant specified in ANSI/ASHRAE Standard 15. In addition, for air transportation consistent with Special Provision A103 of the ICAO Technical Instructions an exception would be provided for refrigerating machines containing 100 g (4 ounces) or less of a flammable, non-toxic liquified gas. This paragraph is also revised for clarity and to reference both International System of Units (SI) and customary units. Part 174 Section 174.26 The section heading would be revised by removing the phrase ``of placarded cars.'' This change clarifies that the prescribed shipping paper requirements apply to any person who accepts hazardous materials for transportation by rail. Section 174.50 As set forth in Sec. 174.50, the Federal Railroad Administration (FRA) has authority to approve for movement a tank car not conforming to the HMR. Since the adoption of the provision, FRA has issued approximately 400 movement approvals for tank cars that no longer conform to the regulations, for reasons such as leaking fittings, accident damage and exceeding the gross rail load. RSPA proposes to expand FRA's approval authority from tank cars to all rail cars. This would allow FRA to grant approval for the movement of covered hopper cars, gondola cars, and other types of railroad equipment when they no longer conform to Federal law, but may safely be moved to a repair location and eliminate the need for exemption for such movements. Part 175 Section 175.25 Paragraph (a)(2)(ii) would be revised to authorize lettering of at least 4 mm (.16 inch) in height, based on RSPA initiative. Currently, the height requirement is 6mm (0.2 inch) minimum for some of the information required on the notification to air passengers of hazardous materials restrictions. The smaller lettering does not significantly impact readability and encourages use of space on signs for other information such as graphics. Section 175.30 An exception in paragraph (d)(1) for inspecting packages of consumer commodities packaged in a freight container would be expanded to include consumer commodities that are palletized or overpacked. RSPA believes that it is impracticable for consumer commodities that are palletized or overpacked to be broken down and inspected by the operator of the aircraft. This amendment would allow consumer commodities that are overpacked or palletized to be handled in the same manner as consumer commodities in freight containers. Part 177 Section 177.848 Paragraph (c) would be revised to clarify that the prohibition against loading or storing cyanides or cyanide mixtures with acids applies only if hydrogen cyanide would be generated when the materials come into contact with each other. Part 178 Section 178.3 RSPA proposes to amend the introductory text to paragraph (a) to clarify that the specification markings on a UN standard packaging may not be marked on a removable component of a packaging. Section 178.345-13 In paragraph (a), a reference to obsolete Secs. 178.346-13(a), 178.347-13(a), and 178.348-13(a) would be removed. Section 178.603 RSPA proposes to revise paragraph (f)(5) to allow a slight discharge from a closure if it ceases immediately after impact with no further leakage. Currently this allowance applied only to drums, jerricans or bags. This proposed change would align the criteria for passing the drop test with international regulations. Section 178.605 RSPA proposes to revise the last sentence in paragraph (d)(1) to correctly reference the maximum filling limits in Sec. 173.24a(d). Section 178.703 RSPA proposes to revise Sec. 178.703(a)(1)(ii) to correctly reference all of paragraph (a) of Sec. 178.702, and not merely paragraphs (a)(1) and (2), for the code number used to designate an IBC design type. Section 178.815 Paragraph (c)(4)(iii) would be added to authorize dynamic compression testing for IBCs in the same manner as is currently authorized for non-bulk packagings. RSPA considers the dynamic compression test to be an equivalent test method and that by allowing more flexibility in the stacking test requirements will provide a cost saving to the regulated industry. Part 179 Section 179.100-20 RSPA proposes to remove the water capacity entry in the table that requires each DOT-105A100W tank car to be [[Page 53170]] stamped with the water capacity in pounds because it is redundant. Section 179.22 requires a tank car to be marked in accordance with Appendix C of the Association of American Railroads (AAR) Tank Car Manual. Section C3.03 of the AAR manual already requires marking the water capacity, in gallons and liters, on the side of the tank car. Consequently, the requirement proposed for deletion is redundant and conflicting with other requirements. Therefore, as a result, its removal will have no effect on safety. Part 180 Section 180.417 RSPA proposes to revise paragraph (a)(2) to allow a cargo tank owner to retain the vehicle certification report and related papers at a company's principal place of business or at the location where the vehicle is housed or maintained, without obtaining prior approval from the Regional Director, Office of Motor Carrier Safety, Federal Highway Administration. This change offers motor carriers greater flexibility in the location where these documents are retained. Regulatory 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. This rule is not significant under the Regulatory Policies and Procedures of the Department of Transportation (44 FR 11034). The costs and benefits associated with this proposed rule are considered to be so minimal as to not warrant preparation of a regulatory impact analysis or regulatory evaluation. This determination may be revised as a result of public comment. B. Executive Order 12612 This proposed rule has been analyzed in accordance with the principles and criteria contained in Executive Order 12612 (``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 pertaining to hazardous materials and requirements respecting 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, fabrication, marking, maintenance, reconditioning, repairing, or testing of a package or container which is represented, marked, certified, or sold as qualified for use in the transportation of hazardous materials. This proposed rule concerns the classification, packaging, marking, labeling, and handling of hazardous materials, among other covered subjects. If adopted as final, this rule would preempt 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 law (49 U.S.C. 5125(b)(2)) provides that if DOT issues a regulation concerning any of the covered subjects after November 16, 1990, DOT must determine and publish in the Federal Register the effective date of Federal preemption. That effective date may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. RSPA requests comments on what the effective date of Federal preemption should be for the requirements in this proposed rule that concern covered subjects. C. Executive Order 13084 This propose 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 would not significantly or uniquely affect the communities, the funding and consultation requirements of the Executive Order do not apply. D. Regulatory Flexibility Act The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an agency to review regulations to assess their impact on small entities unless the agency determines that a rule is not expected to have a significant impact on a substantial number of small entities. This proposed rule would amend miscellaneous provisions in the HMR, generally to clarify those provisions and to relax requirements that are overly burdensome. The proposed changes in this rule are generally intended to provide relief to shippers, carriers, and packaging manufacturers, some of whom are small entities (e.g., governmental jurisdictions and not-for-profit organizations). The costs and benefits associated with this proposed rule are considered to be so minimal as to not warrant preparation of a regulatory impact analysis or regulatory evaluation. Therefore, I certify that this proposal will not, if promulgated, have a significant economic impact on a substantial number of small entities. E. Paperwork Reduction Act Under the Paperwork Reduction Act of 1995, no person is required to respond to a collection of information unless it displays a valid Office of Management and Budget (OMB) control number. This NPRM does not propose any new information collection burdens. The information collection associated with the proposal to provide for nonconforming railcars under Sec. 174.50 is currently being reported under the information collection for exemption applications under Sec. 107.105. Information collection requirements contained in Sec. 174.50 have been approved by the OMB under control number 2137-0559. 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. H. Impact on Business Processes and Computer Systems Many computers that use two digits to keep track of dates will, on January 1, 2000, recognize ``double zero'' not as 2000 but as 1900. This glitch, the year 2000 problem, could cause computers to stop running or to start generating erroneous data. The Year 2000 problem poses a threat to the global economy in which Americans live and work. With the help of the President's Council on Year 2000 Conversion, Federal agencies are reaching out to increase awareness [[Page 53171]] of the problem and to offer support. We do not want to impose new requirements that would mandate business process changes when the resources necessary to implement those requirements would otherwise be applied to the Year 2000 problem. This proposed rule does not mandate business process changes or require modifications to computer systems. Because this proposed rule does not affect organizations' ability to respond to the Year 2000 problem, we do not intend to delay the effectiveness of the requirements.

The test must be conducted at room temperature on an empty, unsealed packaging. The test sample must be centered on the bottom platen of the testing machine. The top platen must be lowered until it comes in contact with the test sample. Compression must be applied end to end. The speed of the compression tester must be one- half inch plus or minus one-fourth inch per minute. An initial preload of 50 pounds must be applied to ensure a definite contact between the test sample and the platens. The distance between the platens at this time must be recorded as zero deformation. The force ``A'' to then be applied must be calculated using the applicable formula: Liquids: A=(n-1)[w+(s x v x 8.3 x .98)] x 1.5; or Solids: A=(n-1)[w+(s x v x 8.3 x .95)] x 1.5 Where: A=applied load in pounds. n=minimum number of containers that, when stacked, reach a height of 3 m. s=specific gravity of lading. w=maximum weight of one empty container in pounds. v=actual capacity of container (rated capacity + outage) in gallons. And: 8.3 corresponds to the weight in pounds of 1.0 gallon of water. 1.5 is a compensation factor that converts the static load of the stacking test into a load suitable for dynamic compression testing. * * * * * PART 179--SPECIFICATIONS FOR TANK CARS 52.
